DETAILED DESCRIPTION

(13) Referring to FIG. 1, a product bagging system 20 includes a product loading station or product bagging assembly 22 according to the present invention. Product bagging system 20 includes a bag feeder/loader or bag delivery 23 that is associated with a payoff system 24 that includes a roll support or loading station 26. A bulk volume, such as a roll or folded supply, of web material is associated with or supported by loading station 26, passed through payoff system 24, and delivered to a printing station 28 prior to being communicated to a product pass through 30 associated with product bagging assembly 22 via bag delivery system 23.

(14) In one embodiment, a roll, which can be a continuous roll of plastic material bags, which may be partially perforated along intended tear or bag opening lines, is fed from roll loading station 26, up through a number of rollers associated with payoff system 24, to the printing station 28. In one embodiment, each bag, while in the continuous roll or folded arrangement of what will ultimately define multiple discrete product containing bags, is attached to the neighboring bags by perforations. Each bag is generally defined by a front side and a back side that are bounded by edges. One or more of the left side edges, right side edges, and bottom edges can be sealed and the top edge or area proximate thereto can be provided with an open or partially perforated top edge portion which can be selectively opened or severed during the product loading process and subsequently sealed to secure the packaged contents within the confines of a respective bag.

(15) In some configurations, the top of the rear or back portion of the bag is attached to the neighboring bag by the above described perforations. Disposed generally proximate the top of the front of the bag is a mouth or lip of the bag that is only attached to the rear portion of the bag at the right side and left side and is free to be manipulated as will be further discussed below. Alternatively, selectively tearable perforations can be formed proximate or at the top edge associated with the front and rear sides of a respective bag and severable to define a desired opening size and shape of each respective bag during product loading. It should, be appreciated that the description above is merely exemplary of a few of many web material containers useable with product bagging system 20.

(16) Regardless of the web material utilized, at the printing station 28, signage, such as a graphic associated with identification of the contents of a package, product or supplier designs such as a company's logo or trademark, as well as shipping information and/or instructions, for example fragile, is preferably printed directly on the bag or printed to a label adhered to a respective bag. After a portion of the web material or a respective label has been printed and/or adhered to a respective bag, a portion of the web material associated with forming a discrete product bag advances to product pass through 30 and is manipulated by operation of product bagging assembly 22 to open the respective bag to have a desired opening, throat, or mouth size and shape for receipt of respective product as described further below.

(17) Product bagging system 20 includes a control system 32, such as computer, that is configured to control the desired sequential operation of one or more of bag feeding system 20, payoff system 24, loading station 26, and/or printing station 28 to effectuate the desired respective operations thereof during a product packaging process. It is appreciated that control system 32 can be configured to receive operational instructions directly from user personnel, such as via a mouse, keyboard, touch screen, or other inputs such as flash drives and/or network connections. As disclosed further below, control system 32 may be programmed to determine how much stroke is available and/or needed from each set of actuators for any given bag opening width and, length desired. In one embodiment, control system 32 is pre-programmed with the available stroke for each set of actuators and configured to allow each set of actuators to be selected for use alone or in combination. Such a consideration reduces the user interaction required to effectuate operation of product bagging assembly 22 in a desired manner from various available product throughput configurations as disclosed further below.

(18) Still referring to FIG. 1, product bagging assembly 22 of product bagging system 20 includes a chassis 34 and a shroud 36 or the like associated with selectively isolating the internal workings of product bagging assembly 22 from dirt, debris, product to be packaged, as well as users or operators. Product loading station 20 can further include one or more hand stations or contacts associated with providing a user's confirmation that the desired product has been associated with pass through 30 and/or the open bag disposed generally thereunder. Although shown in what is commonly understood as a vertical loading configuration, it is appreciated that one or more of product loading station 20, printing station 28, payoff system 24, and/or bag feeding system 20 can be rotationally supported so as to provide vertical, horizontal, or canted or pitched user interaction with product packaging system 20 and specifically product loading station 20. In a preferred embodiment, product packaging system 20 is supported by a cart 38 having one or more casters 40 to accommodate desired or various placement of system 20 within a given operating environment.

(19) Still referring to FIG. 1, bag deliver system 23 includes a conveyor 42 configured to move the web material associated with the strip of bags, toward pass through 30 via a channel or slot 44 formed through facing sides of the bag delivery system 23 and the product bagging assembly 22. Product bagging assembly 22 opens respective bags and then, after product loading, seals the respective bags prior to introduction of a subsequent bag to the space associated with product pass through 30. It is appreciated that chassis 34 and shroud 36 of product bagging assembly 22 could be formed of multiple connected panel-like structures and/or formed as a more unitary structure such that product pass through 30 defines a product inlet 48 and a bagged product outlet 50 that generally overly one another.

(20) It is further appreciated that shroud 36 and chassis 34 can optionally cooperate with one another in a movable manner such that the guard can slide in and out in a direction aligned with the direction of bag introduction, as indicated by arrow 52, relative to one another to provide variable sized product pass through inlet 48 sizes based upon the size of products intended to be packaged. The ability to adjust shroud 36 relative to chassis 34 ensures that, when product is manually loaded, loading personnel are permitted as close as operational permitted relative to inlet 48 to provide an ergonomically desirable position of loading personnel across a range of usable product and bag sizes. Other means of providing an adjustable shroud 36 are envisioned and would not defeat the spirit of the invention.

(21) FIGS. 2-4 show product bagging assembly 22 with shroud 36, various chassis portions, and various bag opening or manipulating assemblies selectively removed from bagging assembly 22. As described further below, it will be appreciated that product bagging assembly can be individualized to achieve the desired operation of product bagging assembly 22 associated with different product and bag shape, size, and configurations.

(22) Product bagging assembly 22 is configured to receive or cooperate with various bag manipulating structures to effectuate a desired opening, packaging, closing, and sealing of a respective empty and packaged product bag. Referring to FIG. 2, product bagging assembly 22 can include one or more product guides 60, supported by a rotatable shaft 62 that is fixed or slideably supported by chassis 34. Upon introduction of a bag to product pass through 30 via slot 44, guides 60 are shaped to accommodate passage of a product along an upper surface 64 generally between the guides and into the volume of an opened bag. Preferably, guides 60 slideably cooperate with shaft 62 in a generally lateral direction, indicated by arrow 67, to accommodate use of guides 60 with bags of various widths.

(23) A drive device 66, such as a motor, cooperates with shaft 62, to attain the desired orientation of guides 60, relative to a staging and loading process. One or more slots 68 associated with chassis 34 can be provided to accommodate a slideable cooperation of shaft 62 in bag opening and closing direction 52 relative to slot 44 to facilitate use of guides 60 throughout the loading process or use of a guide or guides having other shapes. Alternatively, it is appreciated that guides 60 could be biased out of interference with manipulation of bag opening assembly and deflectable in response to user interaction to tilt product into an underlying open bag. It is further appreciated that for some manual and many automated product packaging processes, guides 60 may be omitted or removed from product bagging assembly 22.

(24) As alluded to above, a bag opening assembly 70 is supported by a carriage 72 that is slideable relative to chassis 34 in directions 52. A pressure plate or cross member 74 supports one or more bag tensioning or opening devices 76, such as vacuum assist devices, configured to engage a front facing side of each respective bag. During packaging processes, cross member 74 moves in a closing direction 75 or toward slot 44 to engage bag and subsequently an opening direction 78 to effectuate separation of the alternate sides of a respective bag and thereby forming the opening or mouth associated with the underlying bag. It is appreciated that in some applications, air knife 43 may provide a sufficient open configuration for bags having a hysteresis capable of maintaining an open mouth orientation such that cross member 74 need not engage a respective bag. Commonly, only smaller sized bags are capable of such use of product bagging assembly 22.

(25) In one mode of operation, after a product has been disposed in a respective bag, cross member 54 returns toward slot 44 and compresses a respective bag 21 against a sealing assembly disposed proximate thereof. Before the pressure bar or cross member 54 retracts or disengages the top of a respective bag 21, conveyor 42 can operate in a reverse direction to tear perforations between discrete bags 21 associated with a roll 25 of bags to effectuate separation of a packaged bag 21 from the remaining web material. Once a packaged bag 21 is torn from the roll 25 of bags, cross member 74 can translate in an opening direction associated with product pass through 30 such that the packaged bag 21 drops out of the product bagging assembly. Understandably, other means are known in the industry for separating perforations or even bags, for example using a knife, pulling, pinching or burning, and the use of which would not defeat the spirit of the invention.

(26) When utilized, bag opening devices 76 can slideably cooperate with cross member 74 to achieve the desired positioning of opening devices 76 relative to discrete bags 21 delivered through slot 44. That is, devices 76 can be positioned nearer one another for smaller bags 21 and further from one another for larger bags 21. Bag opening assembly 70 can also include one or more optional tensioners or bag edge retainers 90 that are rotatable about an axis generally aligned with direction 52. Initial opening of a bag 21 can be effectuated by air knife 43 and/or the rotation of one or more fingers 92 associated with retainers 90 into the opening of a respective bag 21 during the opening, loading, and closing of a respective bag 21. Depending on the configuration of the utilized bags 21, fingers 92 and the translation of cross member 74 may cooperate with one another to form a desired bag mouth opening by separation of a partial opening perforation associated with the underlying bag 21. When used to effectuate such manipulation, fingers 92 and cross member 74 cooperate with one another to maintain a secure edge between the opposing faces of each respective bag 21.

(27) Depending on the operational packaging parameters, in some situations it may be preferred to have a wide, but narrow opening, a generally rectilinear or square shaped bag opening, or other bag opening shapes. Cross member 74 and fingers 92, or other finger orientations as described above and below, can each be adjusted to provide the desired bag opening shape. The fingers 92 could also be positioned laterally to help create the rear boundary or trapezoidal shapes associated with the bag openings. If suction mechanisms are utilized as bag opening devices 76, the suction mechanisms can be laterally set relative to shaft 62 to create the desired width of the bag opening. The exact distance between the guides 60 fingers 92, and suction mechanisms 76 can each be independently adjusted to create a bag opening having a desired shape associated with the size of the bag 21 utilized for various bag 21 sizes.

(28) In a preferred embodiment, retainers 80 are also translatable in directions 52 to provide securing of sides of the respective bag 21 that extends between slot 44 and cross member 74 defining the bag 21 opening and closing operations. Such a consideration allows each bag 21 to be presented with a generally taut edge associated with the mouth of a respective bag 21 and generation of flat bag edge during the closing and sealing processes. Understandably, such manipulations may only be utilized during operation of bagging assembly with larger bags 21 suitable to larger product shapes.

(29) Referring to FIGS. 3 and 4, retainers 90 and the drive system associated therewith, may be omitted or removed if utilization of product bagging assembly 22 is intended to be utilized with bags 21 having smaller cross-sectional opening shapes or if other retaining assemblies are utilized. For instance, as shown in FIG. 4, one or more forward oriented retainers 90 may be supported by cross member 74 and movable with carriage 72. Retainers 90 include a finger 92 and are connected to a drive arrangement 94 configured to provide selective rotation of retainers 90 in a direction generally aligned with cross member 74 to allow the selective cooperation of fingers 92, with the volume associated with a respective bag 21.

(30) It is envisioned that for some applications, retainers 90 will provide sufficient bag tension to tolerate operation of product bagging assembly without or without operation of vacuum tensioners 76. It is further appreciated that product guides 60 and the drive arrangement or device 66 associated therewith, may also be omitted or selectively included with product bagging assembly 22 depending upon the nature of the product and the size of the bags associated with use thereof. When utilized, each retainer 90 is supported by a shaft 86 that extends to a retainer drive assembly 88 associated with carriage 74. Drive assembly 88 is operable to effectuate the desired rotation of fingers 82 into and out of the cavity associated with a respective bag.

(31) Referring to FIGS. 5-8, cross member 74 is movable in directions 52 between a bag close position or orientation 100 (FIG. 5), a first bag open position, 102 (FIG. 6), and a second bag open position, 104 (FIGS. 6 and 7) via, operation of one or more prime movers or actuators 106, 108; 110, 112. As explained further below with respect to FIGS. 9-11, a third bag open position can be attained between first and second bag open positions 102, 104 via controlled or desired operation of actuators 106, 108; 110, 112. As disclosed further below, it is further appreciated that each of the various bag open positions can be adjusted such that infinite bag open or product pass through dimensions can be achieved with product bagging assembly 22.

(32) Although each of prime movers 106, 108, 110, 112 are shown as pneumatic linear actuators, it is appreciated that prime movers 106, 108, 110, 112 having other operational methodologies, such as electric, pneumatic and/or combinations thereof, may be utilized. Preferably, prime movers 106, 108, 110, 112 are configured to operate a rate that is not detrimental to product throughput and can accommodate the desired manipulations of the underlying bag between the open, load, close, and seal process without damaging the underlying bag and/or packaged product.

(33) Prime movers 106, 108 each include a housing 114 having a first end 116 that is supported by carriage 72 and a second end 118 associated with a shaft 120 (FIG. 5) that is extendable and retractable relative to the respective housing 114. Opposite ends 122 of cross member 74 slideably cooperate with a shaft 124 during operation of actuators 106, 108, 110, 112 to accommodate the slideable motion of cross member 74 between the fully closed orientation 100, as shown in FIG. 5, and the fully open orientation 104, as shown in FIG. 7. As disclosed further below, it is appreciated that cross member 74 can achieve virtually infinite bag open orientations between the bag close position 100 and a maximum bag open position 104.

(34) Referring to FIGS. 5 and 6, when in the closed orientation 100 shown in FIG. 5, cross member 74 presses a bag disposed against the cross member against a seal 128 disposed proximate bag slot 44. A bag seal element (not visible), such as a heat bar, is extendable and retractable relative to seal 128 such that the bag seal element can be selectively exposed to the pass through 30 to be proximate to or contact a respective bag disposed against cross member 74 to effectuate the bag sealing process alter a bag has been loaded and closed via operation of movable members of the product bagging assembly 22.

(35) It is further appreciated that a cutting element could be disposed proximate seal 128 generally above and/or below the seal element to effectuate separation between adjacent bags daring product packaging operations for bags that are not provided with a pullable separation structure, such as a bag edge or end perforation feature. It is further appreciated that other bag sealing methodologies can be utilized such as gluing, bonding, crimping, etc., such that the heat bar could be omitted depending the users preferences.

(36) Referring to FIGS. 8-11, actuators 110, 112, each include a housing 130 that is positionally secured to a frame 132 that generally underlies bag feeder/loader 23. A ram or shaft 134 slideably cooperates with housing 130 of each respective actuator 110, 112, to extend and retract an arm 136 secured to a distal end 138 of each respective shaft 134. Operation of actuators 110, 112 effectuate translation of arms 136 in bag open and close directions 52.

(37) Arms 136 cooperate with shafts 124 and carriage 72 to effectuate translation of the entirety of actuators 106, 108 during operation of actuators 110, 112 relative to chassis 34 and in direction 52 independent of the operation of actuators 106, 108. Conversely, actuators 106, 108 cooperate with cross member 74 such that cross member 74 is independently movable in direction 52 in response to operation of either of actuators 106, 108 or actuators 110, 112.

(38) Referring to FIGS. 8 and 9, when actuators 106, 108 are fully retracted and actuators 110, 112 are fully extended, the orientation of cross member 74 relative to chassis 34 defines a maximum dimension of the cross-sectional shape associated with product pass through 30. In a preferred embodiment, the distance between seal 128, and a bag facing face 140 associated with product pass through 30 is approximately at least 10 inches. Concurrent operation of actuators 106, 108 in an extension direction and actuators 110, 112 in a retraction direction allows translation of cross member 74 in bag closing direction 75 at nearly twice the operational speed associated with operation of only set of actuators 106, 108 or 110, 112. The speed of operation associated with translation of cross member 74 in bag opening direction 78 is similarly increased by concurrent actuation of actuators 106, 108, 110, 112. Said in another way, the operation of actuators 106, 108, 110, 112 is stacked to accommodate greater translation dimensions without substantially detracting from cycle times associated with use of product bagging assemblies 22 for larger sized bags. It should be appreciated that faster operating actuators, such as electric actuators could be utilized as a viable alternative to providing a desired larger product throughput dimension while maintaining desired product packaging cycle times.

(39) Referring to FIG. 10, when actuators 106, 108 and actuators 110, 112 are extended, the distance between seal 128 and face 140 of cross member 74 associated with product pass through 30 is approximately 6 inches. Operation of actuators 110, 112 between the extended and retracted position allows cyclic operation of product bagging assembly 22 between a bag closed position wherein cross member 74 touches or approximately touches seal 128 and a fully open orientation wherein approximately six inches is associated with the depth of the product pass through 30. Said in another way, if an approximately six inch pass through dimension is all that is required for a given product packaging sequence, actuators 106, 108 can be maintained in an in-active state such that the cyclic translation of cross member 74 is effectuated by operation of actuators 110, 112.

(40) Referring to FIG. 11, when actuators 106, 108 and actuators 110, 112 are in a retracted orientations, the distance between seal 128 and face 140 of cross member 74 is approximately four inches such that actuation of only actuators 106, 108 between the extended and retracted positions provides a product pass through dimension of between approximately zero and approximately four inches. Said in another way, if smaller stroke sizes are desired for packaging of a given product, actuators 110, 112 can be maintained in a static or non-operational condition such that the packaging cycle is accommodated by the cyclic operation of only actuator 106, 108.

(41) It should be appreciated that the various dimensions of approximately four, six, and ten inches associated with product pass through 30 provided above with respect to the extension and retraction or cyclic operation of actuators 106, 108, 110, 112 are merely exemplary and that other product pass through dimensions are envisioned. That is, it is appreciated that there are various methodologies associated with adjusting the stroke length and/or the available translation associated with operation of actuators 106, 108, 110, 112.

(42) For instance, one or both of sets of actuators 106, 108 and 110, 112 could be replaced with actuators having other operating dimensions or stroke lengths. It is further appreciated that when provided as electric actuators, various operational stroke lengths can be defined by operational signals communicated to the respective actuators. As another alternatively, product bagging assembly 22 can include one or more spacers and/or variable length bumpers 146, 148 that could be associated with one or more of shafts 124 and/or the respective shafts associated with one or more of actuators 106, 108, 110, 112. It is further appreciated that one or more lock collars 150 could be associated with shafts 124 and/or the shafts associated with actuators 106, 108, 110, 112, to achieve the desired operating or stroke length and/or translation of cross member 74 and/or carriage 72 relative to product pass through 30. Alternatively, adjustable position limit switches may be implemented and connected to control system 32 to designate the desired operating stroke associated with operation of one or more of actuators 106, 108, 110, 112.

(43) It is further appreciated that arm 136 could also be provided with an adjustment assembly 154, configured to manipulate the operating length associated with extension and retraction of the shaft associated with one or both of actuators 110, 112. It is further appreciated that the mounting arrangement associated with one or both of sets of actuators 106, 108, 110, 112 could be adjusted to manipulate the effective operating stroke associated with the respective set of actuators.

(44) The exemplary adjustment methodologies disclosed, above should not be considered exhaustive and/or mutually exclusive. That is, product bagging assembly 22 may include none, one, or multiple of the features discussed above to achieve the desired degree of adjustability associated with the desired or intended utilization product bagging assembly 22. That is, whereas some user may only consume one bag size or type and not desire or require some or any of the adjustability features disclosed above, more product dynamic users may desire one or more or comparable adjustability features to accommodate utilization of product bagging assembly 22 with various bag and product shapes and sizes within the operable range associate with product bagging assembly 22. Regardless of the adjustability methodology utilized, each allows product bagging assembly 22 to be quickly and conveniently configured for the desired operation associated with the use of product bagging assembly 22 with bags and products having different shapes and sizes.

(45) It is further appreciated that many consumers may already have access to or own bag feeder/loader devices 23 configured to communicate web material bags to product bag loading assemblies similar to product bagging assembly 22. As such, it is envisioned that product bagging assembly 22 be provided as a kit constructed to cooperate with previously acquired bag feeder/loader assemblies 23. It is further appreciated that one or more of actuators 110, 112 may be included in such a kit or omitted if the previously, acquired bag feeder/loader assembly includes a suitable actuator configured to interact with the previously acquired product bagging assembly.

(46) Upon acquisition, connection of product bagging assembly 22 to the pre-acquired bag feeder/loader, and connection of the various actuators/operators to power or pneumatic systems associated with the underlying system and controller 32 allow product bagging assembly 22 to be quickly and conveniently configured to satisfy various user packaging demands and/or preferences. The adjustability and various operating states associated with use of product bagging assembly 22 allows a single bagging assembly to satisfy the various know and possible unknown demands or desires of various types of users, greater product size throughputs than previously available, and at product throughput rates that negligibly affect or improve product bagging process efficiency.
