DETAILED DESCRIPTION

[0065] The present disclosure relates generally to electronic cutting systems, methods, and apparatus. In particular, the present disclosure relates to matless cutting machines and provides technical solutions to a number of technical problems in the art discussed above.

[0066] For example, in one aspect of the matless cutting machines disclosed herein, the machines are configured to receive a material to be cut and to feed that material back and forth through the cutting machine without placing the material on a cutting mat.

[0067] In addition, in one aspect of the cutting machines disclosed herein, the cutting machines automatically align the material being cut without the user manually releasing the material and aligning or realigning the material before and/or during a project. Again, the disclosed cutting machines may do so without the use of more rigid cutting mats.

[0068] Because cutting machines of the present disclosure do not require cutting mats, one aspect of the cutting machines described herein allow for an unlimited length of material to be cut. That is, because the cutting machines described herein do not require the use of cutting mats, the cutting machines are not restricted to cutting only the area provided by a cutting mat. Rather, matless materials of theoretically indefinite length can be fed into the cutting machines and continuously cut while maintaining automatic alignment throughout the project.

[0069] In general, there are four categories of features of cutting machines and materials used with matless cutting machines, as disclosed herein, that enable effective, easy-to-use, automatic alignment of an unlimited length of material without the use of cutting mats. These features allow an unlimited length of material to be fed into a self-aligning cutting machine without the need for cutting mats or manual alignment of material being cut by the user. These four general categories of features include: 1) physical material alignment features of cutting machines; 2) materials and geometries of certain roller system components, including upper and lower rollers, within cutting machines; 3) roller system pinch pressures; and 4) matless material construction and configuration. There are also other categories of features beyond these four listed, as disclosed herein, that enhance the functionality and user interface experience with matless cutting machines.

[0070] One will appreciate, from the present disclosure, that any of the four categories of matless cutting features noted above and further described below may be employed individually, collectively, or in combination with any one or more other category of features, to enhance the matless cutting capabilities of an electronic cutting machine. As such, while some features may be described individually herein, any of the disclosed features and embodiments of matless cutting machines described may be combined with one or more other features or embodiments.

[0071] Example configurations will now be described more fully with reference to the accompanying drawings. Example configurations are provided so that this disclosure will be thorough, and will fully convey the scope of the disclosure to those of ordinary skill in the art. Specific details are set forth such as examples of specific components, devices, and methods, to provide a thorough understanding of configurations of the present disclosure. It will be apparent to those of ordinary skill in the art that specific details need not be employed, that example configurations may be embodied in many different forms, and that the specific details and the example configurations should not be construed to limit the scope of the disclosure.

[0072] With reference to FIGS. 1-2, implementations of the present disclosure relate generally to an exemplary “matless” cutting machine 10, components thereof, and methods of use. Although the term “matless” infers that the cutting machine 10 may operate without conventional cutting mats, which are very rigid, the cutting machine 10 is uniquely configured to operate with a non-conventional workpiece support material that is a component of a non-conventional workpiece (see, e.g., FIGS. 8A, 8B, 9, and 10 illustrating a workpiece 36 including an upper layer 38 defining a workpiece material and a lower layer 40 defining a workpiece support material) that is non-rigid, flexible, rollable, or the like. Accordingly, the term “matless” can be construed to mean and be defined as including the workpiece support material layer 40 that is non-rigid, flexible, rollable, or the like. In other instances, the term “matless” should be construed to mean and be defined as a workpiece support material layer 40 that is “consumable” in the context that the workpiece 36 (that also includes the workpiece material layer 38 that is removably-secured to the workpiece support material layer 40) may be deformed (e.g., cut C as illustrated in FIG. 16A) after being interfaced with the cutting machine 10. Accordingly, as seen at FIGS. 17 and 17A, after the workpiece material 38 is cut C, a first portion 381 of the workpiece material layer 38 may be subsequently removed from the workpiece support material layer 40 while a second portion 382 of the workpiece material layer 38 remains removably-secured to the workpiece support material layer 40. As such, the workpiece support material layer 40 that forms a portion of the workpiece 36 may be configured for single use and disposal thereafter.

[0073] As seen at FIG. 1 the cutting machine 10 includes an outer housing 12 and a door 14. The door 14 is may be arranged in an open configuration to allow material to be inserted into the cutting machine 10. The door 14 may be selectively opened and closed via a hinge mechanism where door 14 connects to the outer housing 12. With reference to FIGS. 1-5, the door 14 is shown arranged in an open configuration in order to illustrate a plurality of internal cutting components of the cutting machine 10. The plurality of internal cutting components may include, but are not limited to, a carriage 16, a roller assembly 18, and other components that will be described in more detail below with reference to other figures.

[0074] When the door 14 is arranged in an open configuration, the workpiece 36, which is fed into cutting machine 10, may be at least partially supported on a working surface 22 of the cutting machine 10. The combination of the workpiece material layer 38 and the workpiece support material layer 40 is hereinafter collectively referred to as a workpiece 36. Thereafter, a tool 20 (e.g., a cutting blade) is configured to impinge into the workpiece 36 (see, e.g., the workpiece material layer 38 of the workpiece 36 at FIGS. 8A, 8B, 9, and 10). In some instances, an upwardly-facing surface of the door 14 (when arranged in an open configuration) may also at least partially define a portion of the working surface 22 that supports the workpiece 36 that is fed into and through the cutting machine 10. In this regard, in some implementations, the upper surface of the door 14 is substantially parallel (e.g., +/−10 degrees) to the working surface 22. In some implementations, the upper surface of the door 14 is substantially coplanar with the working surface 22. Additionally, or alternatively, in at least one embodiment, the cutting machine 10 may not include a door, but, rather, the working surface 22 may be otherwise extendable (e.g., in a telescoping arrangement) in order to increase the surface area of working surface 22.

[0075] As the workpiece 36 is fed forward-and-backward by the roller assembly 18, the carriage 16 manipulates the tool 20 for selectively impinging downwardly onto the workpiece material layer 38 of the workpiece 36. The carriage 16 can also move back-and-forth across the workpiece 36 in order to form cuts in any region of the workpiece material layer 38. Although the Figures illustrate the tool 20 including a cutting blade, the tool 20 being defined by a cutting blade is for exemplary purposes only, and, as such, one skilled in the art will appreciate that other tools (e.g., a scoring tool, an ink pen, or the like) may alternatively be secured and manipulated by the carriage 16.

[0076] The roller assembly 18 is said to move the workpiece 36 forward-and-backward in a Y-direction as the carriage 16 moves back-and-forth in an X-direction, as indicated by a reference coordinate system seen at FIG. 1. As noted above, the carriage 16 houses the tool 20; the tool 20 can be manipulated up-and-down vertically (i.e., a Z-direction) relative to the workpiece 36.

[0077] A rear, top, left perspective view of cutting machine 10 is seen at FIG. 2; in this view, a rear side of the outer housing 12 forms a pass-through slot 24 that allows the workpiece 36 to pass through cutting machine 10 without limiting the length of workpiece 36 being interfaced with the cutting machine 10. During operation, the workpiece 36 may pass into and out of the pass-through slot 24 as needed depending on, for example, one or both of: (1) the length of workpiece 36; and (2) the pattern being cut into the workpiece material layer 38. Thus, exemplary embodiments of the cutting machine 10 described here may include internal cutting components and other operating components such as, for example, motors, gears, belts, and other electronics, arranged so as to not interfere with the workpiece 36 passing all the way through the cutting machine 10 and through pass-through slot 24 during use.

[0078] FIG. 3 illustrates a close-up view of an exemplary implementation of the matless cutting machine with the door 14 arranged in an open configuration whereby a first pair of workpiece guides 26 are shown extending away from the upwardly-facing surface of the door 14. In some instances, the first pair of workpiece guides 26 may define upwardly extending walls oriented longitudinally in the Y-direction. Furthermore, the first pair of workpiece guides 26 may vary in height, length, and shape, so long as the first pair of workpiece guides 26 do not interfere with other components of the cutting machine 10 when the door 14 is arranged in either of the open configuration or the closed configuration.

[0079] Yet even further, the lateral distance in the X-direction between the first pair of workpiece guides 26 is not limited to the arrangement seen at FIG. 3. Accordingly, the first pair of workpiece guides 26 may be fixedly configured in a number of predetermined lateral distances or dynamically selectively spaced apart to a desired lateral distance in order to accommodate a variety materials having different widths that may be interfaced with the cutting machine 10 by being arranged over or upon the working surface 22. As will be described in the following disclosure at FIGS. 8A, 8B, 9, and 10, various embodiments of workpiece support material layers 40 defining the workpiece 36 may be fed into the cutting machine 10 may be constrained laterally in the X-direction by the first pair of workpiece guides 26 as the roller assembly 18 feeds the workpiece 36 forward-and-backward in the Y-direction.

[0080] In addition to the first pair of workpiece guides 26 that are disposed on or extend away from the inner surface of the door 14, with reference to FIG. 4, the cutting machine 10 may also include one or both of an optional second pair of workpiece guides 28 and an optional third pair of workpiece guides 30. Each of the second pair of workpiece guides 28 and the third pair of workpiece guides 30 do not extend from or are disposed on the inner surface of the door 14, but, rather, are disposed on or extend from the working surface 22 of the cutting machine 10 and may be spaced apart at a lateral distance in the X-direction in a substantially similar manner as that of the first pair of workpiece guides 26. The view of FIG. 4 represents an exemplary close-up view of only one side of working surface 22 for illustrative purposes with various guide bars and belts of cutting machine 10 being removed in order to show an unobstructed view of the first, second, and third pairs of workpiece guides 26, 28, 30.

[0081] As shown, the second pair of workpiece guides 28 and the third pair of workpiece guides 30 are aligned longitudinally in the Y-direction with the first pair of workpiece guides 26 in order to accommodate the same width of a workpiece 36 that is fed into cutting machine 10. Each of the first paid of workpiece guides 26, the second set of workpiece guides 28, and the third set of workpiece guides 30 prevent a workpiece 36 from being fed into the cutting machine 10 from travelling too much laterally in the X-direction as the workpiece 36 is fed through cutting machine 10 forward-and-backward in the Y-direction by the roller assembly 18. In effect, the first pair of workpiece guides 26, the second paid of workpiece guides 28, and the third pair of workpiece guides 30 act as bumpers that contact the side edges of the workpiece 36 that are arranged upon or over the working surface 22.

[0082] Accordingly, if a user (not shown) feeds the workpiece 36 into the cutting machine 10 in a misaligned orientation longitudinally in the Y-direction (or, furthermore, in some instances in a further rotated/skewed direction about the Z-axis), the first pair of workpiece guides 26, the second pair of workpiece guides 28, and the third pair of workpiece guides 30 push against the side edges of the workpiece 36 in order to align the workpiece 36 as it is fed into cutting machine 10 through the roller assembly 18. Yet even further, if the workpiece 36 becomes misaligned during an ongoing project or during a cutting procedure, either due to the cutting machine 10 getting bumped or by way of the application of an external force that may knock or jar the workpiece 36 out of alignment, one or more of the first pair of workpiece guides 26, the second pair of workpiece guides 28, and the third pair of workpiece guides 30 protect the workpiece 36 from becoming misaligned, and, as a result, function in a manner that will automatically guide the workpiece 36 back into alignment. Accordingly, one or more of the first pair of workpiece guides 26, the second pair of workpiece guides 28, and the third pair of workpiece guides 30 automatically align and maintain alignment of the workpiece 36 that is fed into the cutting machine 10 during the initial feeding of the workpiece 36 into the cutting machine 10 that may occur, for example, during ongoing projects or during a cutting operation. As such, the function of automatic alignment of a workpiece 36 is effective without the user manually noticing a misalignment of the workpiece 36 and thereafter manually adjusting or successively readjusting the workpiece 36 before use of the cutting machine 10 or during use of the matless cutting machine.

[0083] To further illustrate an exemplary implementation of how the first pair of workpiece guides 26, the optional second pair of workpiece guides 28, and the optional third pair of workpiece guides 30 work in concert in order to align the workpiece 36 fed into the cutting machine 10, with reference to FIG. 5, a top view of an exemplary implementation of the cutting machine 10 is shown. As seen at FIG. 5, the first pair of workpiece guides 26 are disposed or arranged forwardly of or upstream of the tool 20, whereas the third pair of workpiece guides 30 are disposed or arranged rearwardly of or downstream of the tool 20, while the second pair of workpiece guides 28 are arranged between or intermediately (or generally at or near the position of the tool 20 in the Y-direction) with respect to both of the first pair of workpiece guides 26 and the third pair of workpiece guides 30. Other exemplary implementations of the cutting machine 10 may include more than or less than the three workpiece guides 26, 28, 30 that are shown in the exemplary implementation of the cutting machine 10 of FIG. 5; furthermore, each set of the three workpiece guides 26, 28, 30 may be disposed or arranged at other positions, either closer to one another or further apart than that shown at FIG. 5.

[0084] Functionally, the first pair of workpiece guides 26, the optional second pair of workpiece guides 28, and the optional third pair of workpiece guides 30 effectively contribute to automatic alignment of the workpiece 36 (that is non-rigid, flexible, rollable, or the like) as a result of the workpiece 36 not being defined to have a rigid quality like conventional workpiece support mats. Accordingly, the first, second, and third pairs of workpiece guides 26, 28, 30 are sufficiently spaced far enough longitudinally (in the Y-direction) with respect to a predetermined width of the workpiece 36 that is to be guided through the cutting machine 10. For example, a length L (see, e.g., FIG. 5), is the longitudinal moment arm provided by one or more of the first, second, and third pairs of workpiece guides 26, 28, 30 for rotating/realigning a width W (see, e.g., FIG. 5) of the workpiece 36 being fed through the cutting machine 10. The longer the moment arm (i.e., the length L of FIG. 5) provided, the automatic alignment and realignment of the workpiece 36 will be more effective. However, the longitudinal distance in the Y-direction that is available for one or more of the first, second, and third pairs of workpiece guides 26, 28, 30 is limited by the size of cutting machine 10. In one aspect, as noted above, an exemplary arrangement of the first pair of workpiece guides 26 disposed on the upper surface of the door 14 or extendable working surface 22 as described herein increases the available moment arm of one or more of the first, second, and third pairs of workpiece guides 26, 28, 30 extending longitudinally in the Y-direction.

[0085] Along these lines, in some configurations, in order to achieve the function of automatic alignment of a workpiece 36 as noted above, in one or more embodiments, the total length L along which one, some, or all of the first, second, and third pairs of workpiece guides 26, 28, 30 extend longitudinally on the working surface 22 may be at least about 30% of the width W between one, some, or all of the first, second, and third pairs of workpiece guides 26, 28, 30 (or the approximate width W of the workpiece material layer 38 that is to be cut while being supported by the workpiece support material layer 40). In some configurations, the total length L along which some, or all of the first, second, and third pairs of workpiece guides 26, 28, 30 extend longitudinally on the working surface 22 is at least about 40% or at least about 50% of the width W between one, some, or all of the first, second, and third pairs of workpiece guides 26, 28, 30. In other configurations, the total length L along which one, some, or all of the first, second, and third pairs of workpiece guides 26, 28, 30 extend longitudinally on the working surface 22 is at least about 55% of the width W between one, some, or all of the first, second, and third pairs of workpiece guides 26, 28, 30. In yet other configurations, the total length L of one, some, or all of the first, second, and third pairs of workpiece guides 26, 28, 30 that is/are disposed longitudinally on the working surface 22 is at least about 60% of the width W between one, some, or all of the first, second, and third pairs of workpiece guides 26, 28, 30.

[0086] Furthermore, in some configurations, one, some, or all of the first, second, and third pairs of workpiece guides 26, 28, 30 may be one, or a combination, of removable, retractable, and movable in order to accommodate situations when one or both of the workpiece material layer 38 and the workpiece support material layer 40 is/are wider than the width W such that the workpiece 36 can be fed into the cutting machine 10. Such exemplary configurations enable the cutting machine 10 to be compatible with other non-standard dimensions of workpieces 36 and cutting mats, or, for example, when automatic alignment is not utilized and also to guide workpieces 36 defined by any number of widths.

[0087] Referring to FIG. 6, a portion of the exemplary roller system 18 of the cutting machine 10 is shown. The roller assembly 18 is configured to feed the workpiece 36 backward-and-forward in the Y-direction through the cutting machine 10. In some instances, the roller assembly 18 includes upper roller 32 and lower roller 34, which are biased towards each other by a spring or other biasing mechanism (not shown). The upper roller 32 may be rigidly secured to an upper roller bar 35, and the lower roller 34 may be rigidly secured to a lower roller bar (not shown). Alternatively, one or both of the upper roller 32 and the lower roller 34 may not be respectively fixed to a roller bar but otherwise fixed relative to one another as shown. As seen at FIG. 6, in some configurations, the lower roller 34 may be driven by a motor (not shown) while the upper roller 32 is passive (i.e., the upper roller is not driven by a motor). However, in one or more embodiments, the upper roller 32 or both of the upper roller 32 and the lower roller 34 may be actively driven by a motor (not shown). In embodiments where only one of the upper roller 32 or the lower roller 34 is actively driven by, for example, a motor, the other of the upper roller 32 and the lower roller 34 is rotated due to the biasing of the upper roll 32 and the lower roller 34 together. In some configurations, the upper roller 32 and the lower roller 34 are biased together with a large enough force to grip and actuate the workpiece 36 passing between the upper roller 32 and the lower roller 34 without slipping but with a small enough force to allow the workpiece 36 to pass there-between after being loaded into the cutting machine 10.

[0088] The material(s) and geometry of the upper roller 32 and the lower roller 34 at least partially dictate the biasing force provided by the upper roller 32 and the lower roller 34. For example, in general, the force provided by the upper roller 32 and the lower roller 34 acts as the normal force component of the friction between the workpiece 36 and the upper and lower rollers 32, 34; thus, the coefficient of friction of each of the upper roller 32 and the lower roller 34 determines the force necessary for precise and consistent actuation of the workpiece 36 (i.e., the higher the coefficient of friction of the lower roller 34 when the lower roller 34 is driven, for example, the lower the biasing force necessary to create sufficient friction with the workpiece 36 and vice versa).

[0089] In addition, the higher the friction between upper roller 32 and the lower roller 34 and the workpiece 36, the less likely it will be that the workpiece 36 erroneously slips between the upper roller 32 and the lower roller 34. However, as noted above with reference to the exemplary configurations of the first, second, and third pairs of workpiece guides 26, 28, 30 located within cutting machine 10, as the workpiece 36 could be potentially misaligned within the cutting machine 10 (i.e., either when initially fed between the upper roller 32 and the lower roller 34 or during cutting), one or more of the first, second, and third pairs of workpiece guides 26, 28, 30 function as “bumpers” to force the workpiece 36 back-and-forth in the X-direction and into alignment as the workpiece 36 is actuated forward-and-backward in the Y-direction. Accordingly, for the most effective automatic alignment of the workpiece 36 in the cutting machine 10, when the workpiece 36 is pinched between the upper roller 32 and the lower roller 34, the workpiece 36 is preferably able to travel back and forth laterally in the X-direction as the roller assembly 18 draws the workpiece 36 forward-and-backward in the Y-direction between the upper roller 32 and the lower roller 34. Accordingly, the lateral travel of the workpiece 36 between the upper roller 32 and the lower roller 34, while small enough to not negatively affect the accuracy of a certain cut or operation of the tool 20, allows one or more of the first, second, and third pairs of workpiece guides 26, 28, 30 to automatically maintain good material alignment.

[0090] In some configurations, the combination of the biasing force between the upper roller 32 and the lower roller 34 and the material(s) defining each of the upper roller 32 and the lower roller 34, including coefficients of friction thereof, may be balanced such that: 1) the coefficient of friction between the upper roller 32 and the lower roller 34 and the material are small enough (or that the upper roller 32 and the lower roller 34 are “slick” enough) to allow lateral movement (in the X-direction) of the workpiece 36 between the upper roller 32 and the lower roller 34 under the given biasing force; and 2) the biasing force creates enough friction to maintain precise actuation of the workpiece 36, without slippage, in the Y-direction.

[0091] In other configurations, the roller assembly 18 may include an upper roller 32 made of polytetrafluoroethylene (PTFE)-filled polycarbonate material having a static coefficient of friction against a workpiece 36 being actuated of less than 1 (e.g., in some configurations, the average coefficient of friction of the upper roller 32 may be between about 0.05 and 0.50 according to the ASTM D1984 friction test). In other configurations, the roller assembly 18 may include a biasing force between the upper roller 32 and the lower roller 34 of at least about 10 kg-f. In yet other configurations, the roller assembly 18 may include a biasing force between the upper roller 32 and the lower roller 34 between about 10 kg-f (+/−10%) and 14 kg-f (+/−10%). In further configurations, the roller assembly 18 may include a biasing force between the upper roller 32 and the lower roller 34 more than 14 kg-f.

[0092] Also, for example, in some configurations, the average coefficient of friction of the upper roller 32 is between about 0.10 and 0.26 according to the ASTM D1984 friction test. In some instances, the average coefficient of friction of the upper roller 32 is about 0.18 according to the ASTM D1984 friction test. In some instances, the roller assembly 18 may include a biasing force between the upper roller 32 and the lower roller 34 of at least about 10 kg-f. In other instances, the roller assembly 18 may include a biasing force between the upper roller 32 and the lower roller 34 between about 10 kg-f and 14 kg-f. In yet other instances, the roller assembly 18 may include a biasing force between the upper roller 32 and the lower roller 34 more than 14 kg-f. In some embodiments, similar materials having similar properties may also be employed, such as other hard plastics with similarly low static coefficients of friction and so forth. For example, in an exemplary configuration, the upper roller 32 (or either the upper roller 32 and the lower roller 34, if passive) may be formed of polycarbonate, TEFLON®, or a composite polycarbonate-TEFLON® material as noted above.

[0093] In some configurations, if a material defining one or more of the upper roller 32 and the lower roller 34 are defined by a softer, higher friction material, and, thus, a lower force, the lower roller 34 may be defined by a needle-like surface geometry. The needle-like geometry may provide a gripping characteristic that reduces slippage of the workpiece 36 between the upper roller 32 and the lower roller 34.

[0094] Referring to FIG. 7, a perspective view of an exemplary lower roller 34 used in the roller assembly 18 is shown. The lower roller 34 of FIG. 7 is robust enough to withstand the higher forces (e.g., 10 kg-f or more) while maintaining a good grip on the workpiece 36. The lower roller 34 may be defined by a generally cylindrical shape and further includes a textured surface having a plurality of robust, square pyramid-shaped protrusions; such protrusions may be manufactured/formed by milling, lathing, or using other manufacturing methods. One or more other exemplary protrusions shapes may be incorporated into the design of the lower roller 34. In general, the lower roller 34 may include any desirable protrusion surface geometry that provides geometric features that improve gripping with the workpiece 36 while withstanding biasing forces from the opposing configuration of the upper roller 32 and the lower roller 34 of 10 kg-f (+/−10%) or more without breaking with repeated use.

[0095] In other configurations, the upper roller 32 may be formed (e.g., milled) in a substantially similar manner as described above to define protrusions like that of the lower roller 34 while the lower roller 34 is formed from a slick plastic material and operates in a passive manner, so long as the passive roller (e.g., the lower roller 34) includes the slick material described above and the actively driven roller (e.g., the upper roller 32) includes the higher traction, contoured surface geometry noted above, without departing from the functionalities of the roller assembly 18 described herein.

[0096] Furthermore, in other configurations, the cutting machine 10 may include more rollers than the upper roller 32 and the lower roller 34 extending laterally across upper roller bar 35 and the lower roller bar (e.g., some configurations of the cutting machine 10 may include three lower rollers and three upper rollers, four lower rollers and four upper rollers, or more). In order to ensure the best automatic alignment of the workpiece 36 fed through the cutting machine 10, however, multiple upper rollers 32 and lower rollers 34 may be defined by the same (or close to the same) diameter. For example, in at least one exemplary configuration, the diameter of each of a set of multiple lower rollers 34 may be configured to be about plus-or-minus about 5-microns of one another.

[0097] With reference to FIG. 8A, a perspective view of an exemplary workpiece 36 that is configured for use with the cutting machine 10 is shown. The workpiece 36 may include an upper layer defining the workpiece material layer 38 and a lower backing layer defining the workpiece support material layer 40. In some configurations, the tool 20 of the cutting machine 10 may be configured to impinge upon the workpiece material layer 38 but not the workpiece support material layer 40. For example, in some instances, where the tool 20 is a cutting blade, the cutting tool 20 will cut through the workpiece material layer 38 but not the workpiece support material layer 40. More details regarding the material properties and dimensions (including, e.g., a thickness) of the various layers of the workpiece 36 are described in the following disclosure, but, in general, the workpiece support material layer 40 may be configured to withstand the impinging force of the cutting tool 20 or other tools 20 while the workpiece material layer 38 may be a peelable vinyl or other material that may be configured to be penetrated by the cutting tool 20, a scoring tool, or other tools, and subsequently removed from the workpiece support material layer 40 after being deformed by the tool 20. In addition, in some instances, the workpiece support material layer 40 may be more rigid than the workpiece material layer 38 in order to promote automatic alignment of the workpiece 36 as the workpiece 36 is guided by material one or more of the first, second, and third pairs of workpiece guides 26, 28, 30 during use as described above.

[0098] With reference to FIG. 16B, in some configurations, the workpiece material layer 38 may be narrower than the workpiece support material layer 40 such that side portions of the workpiece support material layer 40 extend beyond the workpiece material layer 38 on either edge of the workpiece 36. In such exemplary configurations, the workpiece 36 is configured to be fed into the cutting machine 10 so that side portions of the workpiece support material layer 40 that extend laterally beyond the workpiece material layer 38, as shown at FIGS. 16 and 16B, are the portions of the workpiece 36 that are pinched between the upper roller 32 and the lower roller 34 of the roller assembly 18; in this way, the workpiece material layer 38 is not contacted by the upper roller 32 and the lower roller 34 and is less prone to separating or otherwise bunching, tunneling, or slipping from the workpiece support material layer 40 as side edges of the workpiece 36 contact one or more of the first, second, and third pairs of workpiece guides 26, 28, 30, and/or the upper roller 32 and the lower roller 34 during use. With reference to FIG. 8B, a cross-sectional view of the workpiece 36 is shown whereby the workpiece support material layer 40 extends laterally beyond the workpiece material layer 38 on either end.

[0099] In some configurations, the width of the workpiece support material layer 40 is the same as the workpiece material layer 38 such that no portions of the workpiece support material layer 40 extends beyond the workpiece material layer 38. In such exemplary configurations of the workpiece 36, the workpiece material layer 38 may be pinched between the upper roller 32 and the lower roller 34 when the workpiece 36 is fed into the cutting machine 10; however, in such configurations, the workpiece material layer 38 may be adhered securely enough to the workpiece support material layer 40 so that the workpiece material layer 38 is not negatively affected by forces from the upper roller 32 and the lower roller 34 or one or more of the first, second, and third pairs of workpiece guides 26, 28, 30.

[0100] With reference to FIG. 9, a cross-sectional view of an exemplary workpiece 36′ is shown. As seen at FIG. 9, an exemplary workpiece material layer 38′ may be removably secured to an exemplary workpiece support material layer 40′ by an acrylic release adhesive layer 39′. Furthermore, in some configurations, the workpiece support material layer 40′ may be comprised of polyethylene terephthalate (PET); in some instances, the workpiece support material layer 40′ may be about 0.175 mm thick. In a substantially similar manner as noted above, the workpiece support material layer 40′ may be configured to withstand forces from the tool 20 without being penetrated; as such, the workpiece support material layer 40′ may generally form a substantial portion of the total thickness of the workpiece 36′. For example, in some configurations, the workpiece support material layer 40′ may be at least about 30% of the total thickness of the workpiece 36′. In other configurations, the workpiece support material layer 40′ may be at least about 35% of the total thickness of the workpiece 36′. In yet other configurations, the workpiece support material layer 40′ may be at least about 40% of the total thickness of the workpiece 36′.

[0101] Referring to FIG. 10, a cross-sectional view of another exemplary of a workpiece 36″ is shown. As seen at FIG. 10, an exemplary workpiece material layer 38″ is releasably secured to an exemplary multi-layered workpiece support material layer 40″, which may include an intermediate PET liner layer 41″ that may be about 0.15 um thick and a silicone release adhesive layer 43″. In other configurations, the intermediate PET liner layer 41″ may be secured to a 0.025 mm thick PET workpiece support material layer 40″ by a Sum print adhesive layer 45″. In some configurations, the workpiece support material layer 40″ may include a polypropylene (PP) or PET film having a thickness approximately equal to about 0.12 mm.

[0102] Other combinations of layers, including various materials, thicknesses, and arrangement may also be formed to be used as a workpiece that is configured for use in the cutting machine 10. Accordingly, the exemplary workpieces 36, 36′, 36″ described herein and other embodiments thereof may be configured to be rigid enough to be automatically guided and aligned within the cutting machine 10 described herein without the use of conventional, relatively rigid, heavy-duty cutting mats. However, one skilled in the art will appreciate that the materials, thicknesses, and arrangement of layers of defining the exemplary workpieces 36, 36′, 36″ described herein are given only as non-limiting examples of appropriate materials. Other combinations, material layers, and thicknesses thereof, can also be used with the cutting machine 10. In general, a total thickness of the exemplary workpieces 36, 36′, 36″ may vary between about 0.15 mm to about 0.40 mm or thicker.

[0103] The exemplary workpieces 36′, 36″ shown in FIGS. 9 and 10 are examples of workpieces that are configured for use that results in auto-alignment within the cutting machine 10, but also inexpensive enough to produce at a large scale with a low enough consumer price point to be repeatably purchased and used as a consumable. In addition, the exemplary workpieces 36, 36′, 36″ of the present disclosure are flexible enough to be rolled or otherwise efficiently packaged in large quantities without plastically or permanently deformation (as opposed to conventional, rigid, heavy-duty, and expensive cutting mats) that are made with more expensive, thicker materials. Because of the associated expense of conventional, rigid, heavy duty cutting mats, such cutting mats are meant to be reused, thus limiting cutting area and the length as described above that are associated with the exemplary “consumable” workpieces 36, 36′, 36″. In contrast, the exemplary workpieces 36, 36′, 36″ of the present disclosure can be inexpensively sold in large quantities and cut as a consumable product, thus enabling cost-effective, limitless cutting lengths for end users.

[0104] Although the following disclosure is directed to the exemplary workpiece 36, the following disclosure may also apply to the exemplary workpieces 36′, 36″. The material defining the workpiece material layer 38 may vary depending on the needs or wants of the end user. For example, some materials defining the workpiece material layer 38 may be opaque, whereas other materials defining the workpiece material layer 38 may be transparent, and yet other materials defining the workpiece material layer 38 may be semi-transparent, or a combination thereof. In at least some configurations of the cutting machine 10 described herein, a material sensor (not shown) may be disposed above working surface 22, which may detect the type and/or color of the material defining the workpiece material layer 38 being fed though the cutting machine 10. In some configurations, such a material sensor may be disposed rearwardly of the tool 20. In other configurations, such a sensor may be disposed elsewhere within the cutting machine 10. In order to detect a range of materials defining the workpiece material layer 38, including transparent or semi-transparent materials defining the workpiece material layer 38, the material sensor may be disposed at an angle with respect to the working surface 22. The specific angle of the material sensor may vary but is such that a wide range of transparencies can be detected by the sensor. In some examples, transparent materials defining the workpiece material layer 38 are more difficult to detect with the sensor aligned normal to the material defining the workpiece material layer 38 than opaque materials. However, the angle of the sensor and/or a light source detected by the sensor in relation to the material defining the workpiece material layer 38 being detected is optimized based on a range of transparent material properties, such as angle of incidence, to more effectively detect transparent and semi-transparent materials defining the workpiece material layer 38.

[0105] In addition to the various embodiments of the first, second, and third pairs of workpiece guides 26, 28, 30, the roller assembly 18, and the workpiece 36 described herein, other features of the cutting machine 10 may be utilized to enhance matless cutting and improve user experiences. For example, with reference to FIG. 11, an exemplary material sensing mechanism 42 is shown disposed in front of the upper roller 32 and adjacent to a workpiece guide of the second pair of workpiece guides 28. The sensing mechanism 42 may also be disposed elsewhere in one or more other embodiments, such as, for example, next to the upper roller 32 and the workpiece guide of the second pair of workpiece guides 28 or elsewhere within the cutting machine 10. The sensing mechanism 42 may function in a manner that detects the presence and thickness of the workpiece 36 that is fed into the cutting machine 10 upon or over the working surface 22.

[0106] With reference to FIG. 11, a first end portion 48 of a rocker arm 44 is shown extending upwardly through an opening in working surface 22. The first end portion 48 may be rounded in order to allow the workpiece 36 to be inserted between the first end portion 48 and an upper wall 46 of the workpiece guide of the second pair of workpiece guides 28, thereby forcing the rocker arm 44 downward (e.g., Z-direction). With reference to FIG. 12, the rocker arm 44 is shown disposed below the working surface 22. The rocker arm 44 may be rotationally connected to a housing at a pivot point 52 such that when the workpiece 36 is inserted into the cutting machine 10 as described above, the first end portion 48 of the rocker arm 44 is pushed downwardly and then the second end portion 50 of the rocker arm 44 is rotated up. The second end portion 50 interfaces with a sensor near the second end portion 50, which detects the movement and/or presence of the second end portion 50 relative to the sensor, thus detecting when the workpiece 36 has been fed into the cutting machine 10 as well as the thickness of the workpiece support material layer 40.

[0107] The upper wall 46 that extends horizontally from the second material guide 28 is advantageously arranged so as to keep the workpiece 36 from raising off the working surface 22 during use. In some configurations, the rocker arm 44 may be disposed within the X-Z plane. In this way, regardless of whether the workpiece 36 is actuated forward or backward in the Y-direction, any risk of friction lock against the upper wall 46 is mitigated because the horizontal component (in the X-direction) of the rotation of the first end 48 of the rocker arm 44 is perpendicular to the Y-direction of the workpiece 36 traveling between the first end 48 of the rocker arm 44 and the upper wall 46. In addition, the lateral disposition of the rocker arm 44 within the X-Z plane (e.g., for pivotal movement about an axis extending substantially (e.g., +/−10%) parallel to the Y-axis) allows for a thinner form factor of the cutting machine 10 in the Y-direction in general, as compared to a rocker arm 44 extending in the Y-Z plane (e.g., for pivotal movement about an axis extending substantially parallel to the X-axis).

[0108] Once the workpiece 36 is detected, the upper roller 32 and the lower roller 34 may be activated to auto-feed the workpiece 36 into the cutting machine 10. The upper roller 32 and the lower roller 34 or motor(s) (not shown) actuating one or both of the upper roller 32 and the lower roller 34 may also include one or more sensors (not shown) that detect resistance to rolling (e.g., if a user tries to pull the workpiece 36 out during an ongoing project, one or more of the upper roller 32 and the lower roller 34 may be activated in order to push the workpiece 36 out of the cutting machine 10).

[0109] In some configurations, the sensing mechanism 42 may include a rib 43 protruding downwardly from a lower surface of the upper wall 46. The rib 43 may functionally decrease the space between the upper wall 46 and the working surface 22, which allows for a shorter arm at the second end portion 50 of the rocker arm 44 that interfaces with the sensor. This allows for a smaller space provided for the sensor while maintaining a larger detecting range using easily moldable parts. In some configurations, the sensing mechanism 42 may be capable of detecting workpiece 36 ranging between about 0.18 mm thick to about 0.5 mm thick.

[0110] With reference to FIG. 13, other configurations of the cutting machine 10 may include a material roll holder 54. As noted above, the workpiece 36 may be configured to be flexible enough to be efficiently packaged and shipped, for example in a roll. A roll (see, e.g., 36R at FIGS. 14-17) of workpiece 36 allows large lengths of workpiece 36 to be stored in a small or reduced volume. However, long lengths of rolled workpiece 36 may be difficult to handle during cutting operations of the cutting machine 10. By incorporating or associating the roll holder 54 with the cutting machine 10, an end user can place a roll 36R of workpiece 36 to be cut near the cutting machine 10 between sidewalls 58 of the material roll holder 54 and on top of roll guides 56 of the material roll holder 54. With reference to FIGS. 14-15, the roll 36R of workpiece 36 can rotate in place on top of the roll guides 56 and between the sidewalls 58; furthermore, in some configurations, the roll 36R of workpiece 36 can rotate in place on top of the roll guides 56 and between the sidewalls 58 after a distal end 36D is disposed within the cutting machine 10 such that the upper roller 32 and the lower roller 34 of the cutting machine 10 pull or reel a portion of the length (see, e.g., L.sub.36 at FIG. 15) of the roll 36R of workpiece 36 into the cutting machine 10. Accordingly, in some configurations, the reeled portion of the length L.sub.36 of the workpiece 36 from the roll 36R of the workpiece 36 can be fed through a guide slot 60 of the material roll holder 54 in order to ensure horizontal alignment of the workpiece 36 with the working surface 22 of the cutting machine 10 as the workpiece 36 is reeled from the roll 36R of the workpiece 36 for subsequent feeding into the cutting machine 10 by the upper roller 32 and the lower roller 34. In other configurations, the roll holder 54 may also include a razor blade 62 or other cutting mechanism guided by an upper wall of the guide slot 60 that permits easy and convenient cutting of a reeled length L.sub.36 of the workpiece 36 from the roll 36R of the workpiece 36 when a project is finished.

[0111] In yet other configurations of the roll holder 54, one or more damping mechanisms and/or springs (not shown) may be included in order to control a rate of rotation of the roll 36R of the workpiece 36 that is reeled from the roll holder 54 during use. Damping mechanisms may, for example, prevent the workpiece 36 that is reeled from the roll 36R of the workpiece 36 from over-rotation due to the inertia of the roll 36R of the workpiece 36 being further rotated even after one or both of the upper roller 32 and the lower roller 34 has/have stopped feeding a desired amount of reeled length L.sub.36 the workpiece 36 from the roll 36R of the workpiece 36 into the cutting machine 10.

[0112] Conversely, spring loaded mechanisms may also function to oppose forces from the upper roller 32 and the lower roller 34 so that the roll 36R of the workpiece 36 extending from or being reeled from the roll holder 54 into the cutting machine 10 remains taut, particularly when the upper roller 32 and the lower roller 34 push the workpiece 36 back out toward the roll holder 54 during a cutting operation.

[0156] The articles “a,” “an,” and “the” are intended to mean that there are one or more of the elements in the preceding descriptions. The terms “comprising,” “including,” and “having” are intended to be inclusive and mean that there may be additional elements other than the listed elements. Additionally, it should be understood that references to “one embodiment” or “an embodiment” of the present disclosure are not intended to be interpreted as excluding the existence of additional implementations that also incorporate the recited features. Numbers, percentages, ratios, or other values stated herein are intended to include that value, and also other values that are “about” or “approximately” the stated value, as would be appreciated by one of ordinary skill in the art encompassed by implementations of the present disclosure. A stated value should therefore be interpreted broadly enough to encompass values that are at least close enough to the stated value to perform a desired function or achieve a desired result. The stated values include at least the variation to be expected in a suitable manufacturing or production process, and may include values that are within 5%, within 1%, within 0.1%, or within 0.01% of a stated value.

[0157] A person having ordinary skill in the art should realize in view of the present disclosure that equivalent constructions do not depart from the spirit and scope of the present disclosure, and that various changes, substitutions, and alterations may be made to implementations disclosed herein without departing from the spirit and scope of the present disclosure. Equivalent constructions, including functional “means-plus-function” clauses are intended to cover the structures described herein as performing the recited function, including both structural equivalents that operate in the same manner, and equivalent structures that provide the same function. It is the express intention of the applicant not to invoke means-plus-function or other functional claiming for any claim except for those in which the words ‘means for’ appear together with an associated function. Each addition, deletion, and modification to the implementations that falls within the meaning and scope of the claims is to be embraced by the claims.

[0158] The terms “approximately,” “about,” and “substantially” as used herein represent an amount close to the stated amount that still performs a desired function or achieves a desired result. For example, the terms “approximately,” “about,” and “substantially” may refer to an amount that is within less than 5% of, within less than 1% of, within less than 0.1% of, and within less than 0.01% of a stated amount. Further, it should be understood that any directions or reference frames in the preceding description are merely relative directions or movements. For example, any references to “up” and “down” or “above” or “below” are merely descriptive of the relative position or movement of the related elements.

[0159] The present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The described embodiments are to be considered in all respects only as illustrative and not restrictive. The scope of the invention is, therefore, indicated by the appended claims rather than by the foregoing description. All changes that come within the meaning and range of equivalency of the claims are to be embraced within their scope.
