[0015] FIG. 1 is an exemplary can decorator;

[0016] FIG. 2 is an exemplary automatic registration and color adjustment system according to a non-limiting, example embodiment of the disclosed concept;

[0017] FIG. 3 is a schematic diagram of a plate cylinder with an associated inking station having an ink fountain and a roller assembly with temperature sensing and adjustment in accordance with a non-limiting, example embodiment of the disclosed concept; and

[0018] FIG. 4 is a flow chart for a method of automatic registration and color adjustment according to a non-limiting, example embodiment of the disclosed concept.

DETAILED DESCRIPTION OF THE INVENTION

[0019] It will be appreciated that the specific elements illustrated in the figures herein and described in the following specification are simply exemplary embodiments of the disclosed concept, which are provided as non-limiting examples solely for the purpose of illustration. Therefore, specific dimensions, orientations, assembly, number of components used, embodiment configurations and other physical characteristics related to the embodiments disclosed herein are not to be considered limiting on the scope of the disclosed concept.

[0020] Directional phrases used herein, such as, for example, clockwise, counterclockwise, left, right, top, bottom, upwards, downwards and derivatives thereof, relate to the orientation of the elements shown in the drawings and are not limiting upon the claims unless expressly recited therein.

[0021] As used herein, the singular form of a, an, and the include plural references unless the context clearly dictates otherwise.

[0022] As used herein, structured to [verb] means that the identified element or assembly has a structure that is shaped, sized, disposed, coupled and/or configured to perform the identified verb. For example, a member that is structured to move is movably coupled to another element and includes elements that cause the member to move or the member is otherwise configured to move in response to other elements or assemblies. As such, as used herein, structured to [verb] recites structure and not function. Further, as used herein, structured to [verb] means that the identified element or assembly is intended to, and is designed to, perform the identified verb. Thus, an element that is merely capable of performing the identified verb but which is not intended to, and is not designed to, perform the identified verb is not structured to [verb].

[0023] As used herein, associated means that the elements are part of the same assembly and/or operate together or act upon/with each other in some manner. For example, an automobile has four tires and four hub caps. While all the elements are coupled as part of the automobile, it is understood that each hubcap is associated with a specific tire.

[0024] As used herein, the statement that two or more parts or components are coupled shall mean that the parts are joined or operate together either directly or indirectly, i.e., through one or more intermediate parts or components, so long as a link occurs. As used herein, directly coupled means that two elements are directly in contact with each other. As used herein, fixedly coupled or fixed means that two components are coupled so as to move as one while maintaining a constant orientation relative to each other. As used herein, adjustably fixed means that two components are coupled so as to move as one while maintaining a constant general orientation or position relative to each other while being able to move in a limited range or about a single axis. For example, a doorknob is adjustably fixed to a door in that the doorknob is rotatable, but generally the doorknob remains in a single position relative to the door. Further, a cartridge (nib and ink reservoir) in a retractable pen is adjustably fixed relative to the housing in that the cartridge moves between a retracted and extended position, but generally maintains its orientation relative to the housing. Accordingly, when two elements are coupled, all portions of those elements are coupled. A description, however, of a specific portion of a first element being coupled to a second element, e.g., an axle first end being coupled to a first wheel, means that the specific portion of the first element is disposed closer to the second element than the other portions thereof. Further, an object resting on another object held in place only by gravity is not coupled to the lower object unless the upper object is otherwise maintained substantially in place. That is, for example, a book on a table is not coupled thereto, but a book glued to a table is coupled thereto.

[0025] As used herein, the statement that two or more parts or components engage one another means that the elements exert a force or bias against one another either directly or through one or more intermediate elements or components. Further, as used herein with regard to moving parts, a moving part may engage another element during the motion from one position to another and/or may engage another element once in the described position. Thus, it is understood that the statements, when element A moves to element A first position, element A engages element B, and when element A is in element A first position, element A engages element B are equivalent statements and mean that element A either engages element B while moving to element A first position and/or element A either engages element B while in element A first position.

[0026] As used herein, correspond indicates that two structural components are sized and shaped to be similar to each other and may be coupled with a minimum amount of friction. Thus, an opening which corresponds to a member is sized slightly larger than the member so that the member may pass through the opening with a minimum amount of friction. This definition is modified if the two components are to fit snugly together. In that situation, the difference between the size of the components is even smaller whereby the amount of friction increases. If the element defining the opening and/or the component inserted into the opening are made from a deformable or compressible material, the opening may even be slightly smaller than the component being inserted into the opening. With regard to surfaces, shapes, and lines, two, or more, corresponding surfaces, shapes, or lines have generally the same size, shape, and contours.

[0027] As used herein, the term number shall mean one or an integer greater than one (i.e., a plurality). That is, for example, the phrase a number of elements means one element or a plurality of elements. It is specifically noted that the term a number of [X] includes a single [X].

[0028] As used herein, about in a phrase such as disposed about [an element, point or axis] or extend about [an element, point or axis] or [X]degrees about an [an element, point or axis], means encircle, extend around, or measured around. When used in reference to a measurement or in a similar manner, about means approximately, i.e., in an approximate range relevant to the measurement as would be understood by one of ordinary skill in the art.

[0029] As used herein, an elongated element inherently includes a longitudinal axis and/or longitudinal line extending in the direction of the elongation.

[0030] As used herein, generally means in a general manner relevant to the term being modified as would be understood by one of ordinary skill in the art.

[0031] As used herein, substantially means for the most part relevant to the term being modified as would be understood by one of ordinary skill in the art.

[0032] As used herein. at means on and/or near relevant to the term being modified as would be understood by one of ordinary skill in the art.

[0033] Example embodiments of the disclosed concept provide an automatic registration and color adjustment device, system and method for printing labels on undecorated cans during a can manufacturing process. Upon receiving outputs of a plurality of sensors including an ambient temperature sensor and a component temperature sensor, the automatic registration and color adjustment device determines an adjustment to one or more components of a can decorator based on the outputs and previous adjustments information associated with the can decorator made to one or more can decorator components in response to a specific temperature change associated with the adjusted can decorator components, and controls the can decorator to make the determined adjustment. Such automatic registration and color adjustment is advantageous in that it proactively adjusts the can decorator immediately upon detecting temperature change that requires the adjustment, rather than waiting until detection of a defect in printed labels subsequently as required by the conventional registration and color adjustment systems and methods, thereby significantly reducing can spoilage and saving time. Based on collected and stored data including at least previous adjustments made and corresponding sensor information that are typically discarded, the automatic registration and color adjustment device instantly determines a type and/or a degree of adjustment required for corresponding current temperature change, and immediately controls the can decorator to make the adjustment required, thereby significantly reducing the amount of can spoilage that would otherwise result when the conventional registration and color adjustment systems using ad hoc manual adjustments based on the guesswork are applied.

[0034] FIG. 2 illustrates an automatic registration and color adjustment system 10 in accordance with a non-limiting, example embodiment of the disclosed concept. FIG. 3 is a schematic diagram of a plate cylinder 31 with an associated inking station 32 having an ink fountain 33 and a roller assembly 34 with temperature sensing and adjustment in accordance with a non-limiting, example embodiment of the disclosed concept. The automatic registration and color adjustment system 10 is described with reference to FIGS. 2-3. The automatic registration and color adjustment system 10 includes a can decorator 2, a plurality of sensors 200,202,204,210,212,220, a plurality of temperature control elements 300,302, and an automatic registration and color adjustment device 1. The plurality of sensors include, e.g., without limitation, ambient temperature sensors 204 structured to sense an ambient temperature associated with the can decorator 2 and component temperature sensors structured to sense a component temperature associated with one or more components of the can decorator 2, such as ink temperature sensors 200,202. The plurality of sensors may also include humidity sensors 210,212 and visual sensors 220.

[0035] Ink temperature sensors 200,202 may be, for example, a contact ink temperature sensor 200 that senses temperature via direct contact with the ink, or a non-contact ink temperature sensor 202 that senses temperature without direct contact. The ink temperature sensors 200,202 may be disposed at any suitable location in each inking station 32, e.g., without limitation, at the blanket wheel, at a mandrel, at various points on the roller assembly, in the fountain 33, etc. Humidity sensors 210,212 may be disposed adjacent to or in proximity to the one or more ink temperature sensors 200,202 and structured to measure humidity associated with respective components of the inking station 32. An ambient temperature sensor 204 may be disposed at any suitable location, e.g., at or in proximity to the can decorator 2. If the ambient temperature sensor 204 is disposed in close proximity to a can decorator component, e.g., a plate cylinder, it may detect temperature of the can decorator component. The visual sensors 220 may be cameras that are disposed at any suitable locations in the can making process such as, for example and without limitation, at a chain-type output conveyor 30, a transfer wheel, inside a curing oven, or any other suitable locations, and structured to capture images of cans 16 as they pass through an inspection window.

[0036] Temperature control elements 300,302 may be disposed at any suitable location. For example, a temperature control element may be, e.g., without limitation, a heating element 300 disposed at the fountain 33 of each inking station 32. In another example, a temperature control element 302 may be, e.g., without limitation, cooling ports that are included in one or more of the rolls of the roller assembly and/or the plate cylinder 31.

[0037] In general, the properties of the ink can be altered as a result of a change in ambient temperature and component temperature, and allow for the most optimal and efficient ink application to the print blanket and can 16 for each ink type. As a result of the change in temperature, the printed cans 16 may include, e.g., without limitation, image registration error, ink density error, ink color error, ink smearing, other image defects. In order to eliminate or reduce such defects, an adjustment to one or more can decorator components needs to be made in response to detecting the temperature change. Conventionally, can decorator operators manually adjust can decorator components by looking at the defects on the cans. However, by the time the defects are detected, thousands of can spoilage have already occurred. Further, such manual adjustment is based on the guesswork of the operators and repeated until the defects are corrected, resulting further can spoilage and wasting manufacturing time. In addition, any information used to make the manual adjustments as well as the adjustments are not stored, thereby wasting useful information that can be utilized for future adjustments. The automatic registration and color adjustment device 1 of the disclosed concept advantageously collects and stores such previous adjustment information and significantly reduces such can spoilage by automatically making appropriate adjustments to can decorator components based on the previous adjustment information.

[0038] The automatic registration and color adjustment device 1 is coupled to at least the can decorator 2, sensors 200,202,204,210,212,220 and the ink temperature control element 300,302. The automatic registration and color adjustment device 1 may be disposed within a control station 100 structured to control the operation of the can decorator 2 and the components thereof. The control station 100 may be, e.g., without limitation, a computer, a workstation, etc. disposed in vicinity of the can decorator 2. While FIGS. 2 and 3 illustrate the automatic registration and color adjustment device 1 disposed within the control station 100, it will be appreciated that the automatic registration and color adjustment device 1 may be a standalone device, e.g., without limitation, a PC or workstation solely structured to automatically create labels without departing from the scope of the disclosed concept. The automatic registration and color adjustment device 1 may be, for example and without limitation, a microprocessor, a microcontroller, or some other suitable processing device or circuitry. It may include memory, which can be any of one or more of a variety of types of internal and/or external storage media such as, without limitation, RAM, ROM, EPROM(s), EEPROM(s), FLASH, and the like that provide a storage register, i.e., a machine readable medium, for data storage such as in the fashion of an internal storage area of a computer, and can be volatile memory or nonvolatile memory. The memory includes instructions or codes for performing the automatic registration and color adjustment operations. It is structured to also store current and previous adjustment information. The memory may also include machine learning algorithm configured to train based on the stored data and execute the instructions based on the training.

[0039] The automatic registration and color adjustment device 1 is communicatively coupled to the can decorator 2 in a wired or wireless connection and structured to receive outputs of the plurality of sensors 200,202,204,210,212,220, determine an adjustment to a one or more components of the can decorator 2 based on the outputs and previous adjustment information, and control the can decorator 2 to make the determined adjustment. The previous adjustment information is collected and stored over a predefined period, e.g., without limitation, at least a day, and updated continuously by the automatic registration and color adjustment device 1. The previous adjustment information includes a specific temperature change, date and time associated with the specific temperature change, effects of the specific temperature change on one or more specific can decorator components, a specific type and/or a degree of adjustment made to the one or more specific can decorator components in response to the specific temperature change, and correlation data between the specific temperature change, the date and time associated with the specific temperature change, the effects thereof and the specific type and/or degree of adjustment made. It is to be understood that a temperature change may accompany corresponding humidity change, and thus the previous adjustment information may be based on the temperature change as well as the corresponding humidity change where it may not be specifically stated as such. For determining an adjustment to one or more components of the can decorator 2, the automatic registration and color adjustment device 1 is further structured to compare current temperature change to the previous temperature changes in the correlation data and determine a type and/or a degree of the adjustment. The automatic registration and color adjustment device 1 controls the can decorator 2 to make the adjustment based on the determined type and/or degree.

[0040] For example, the ink temperature sensor 200 outputs temperature information at respective ink fountain 33 to the automatic registration and color adjustment device 1. The automatic registration and color adjustment device 1 receives and analyzes the output of the ink temperature sensor 200, and determines if an adjustment to the respective ink fountain 33 is to be made based on the output and the correlation data. For example, if the automatic registration and color adjustment device 1 detects temperature changing at the respective ink fountain 33 to be outside of a threshold (e.g., without limitation, an optimal ink temperature ranging between 95 and 105 F.), it causes the temperature control element 300 disposed at the respective ink fountain 33 to control the temperature thereof. That is, the automatic registration and color adjustment device 1 activates the temperature control element 300 and raises the temperature at the ink fountain 33 to be within the threshold such that any further detects can be prevented immediately. In another example, the ink temperature sensor 202 outputs temperature information associated with adjacent ink rollers, fountain blades, and/or plate cylinder 31. The automatic registration and color adjustment device 1 receives and analyzes at least the output of the ink temperature sensor 202, and determines if an adjustment to the associated roller(s), fountain blades, and/or plate cylinder 31 (e.g., translational, circumferential, and/or plate pressure adjustments) is to be made based on the output and the correlation data. That is, if the automatic registration and color adjustment device 1 detects temperature changing at one or more ink rollers to be outside of the threshold, it causes the temperature control element 302 disposed adjacent to the one or more ink rollers to control the temperature thereof. For example, if the temperature at one or more ink rollers has risen, e.g., without limitation, due to overheating of the ink rollers as a result of continuous operation, the automatic registration and color adjustment device 1 activates the temperature control element 302, which in turn cools down the temperature at the overheated ink roller(s) to be within the threshold such that any further detects can be prevented immediately.

[0041] In yet another example, the ink temperature sensor 202 or an ambient temperature sensor 204 in proximity to a plate cylinder 31 outputs temperature information associated with the plate cylinder 31 to the automatic registration and color adjustment device 1. The automatic registration and color adjustment device 1 receives and analyzes the output of the ink temperature sensor 202 or the ambient temperature sensor 204, and determines an adjustment to the plate cylinder 31. For example, upon detecting a temperature change that has been shown to cause expansion or contraction of the plate cylinder 31 (e.g., without limitation, a translational adjustment assembly, a circumferential adjustment assembly of respective plate cylinder shaft, and/or plate pressure, etc.) based on the correlation data, the automatic registration and color adjustment device 1 may, e.g., without limitation, cause an affected can decorator component (e.g., without limitation, the translational adjustment assembly, the circumferential assembly, and/or plate pressure) to be moved such that the image registration and ink on the cans 16 are printed as specified by the label specification; and/or activate the temperature control element 302 until the temperature returns to the threshold. In some examples, the affected can decorator components include e.g., without limitation, a plate cylinder(s) and/or can decorators components surrounding the plate cylinder(s), e.g., without limitation, a translational adjustment assembly of plates, a circumferential assembly of the plates, a plate pressure (e.g., without limitation, a plate pressure spring), fountain blades, rollers, and/or any other can decorator components that may be affected by temperature changes.

[0042] In yet another example, if the automatic registration and color adjustment device 1 receives outputs of ink temperature sensors 200,202 and detects a temperature change at one or more elements in the associated inking station 32 that requires color adjustment based on the correlation data, the automatic registration and color adjustment device 1 determines a type of color adjustment to be made and automatically causes the color adjustment to occur immediately. For example, if the automatic registration and color adjustment device 1 detects a temperature change that has been shown to alter the ink density based on the correlation data, it automatically controls various components of the can decorator 2 such as, for example, plate pressure or pneumatic ductor interval to adjust ink density to a desired or specified level by a label specification.

[0043] These examples are for illustrative purposes only, and thus it will be appreciated that other types and/or degrees of adjustments to the can decorator 2 may be made as appropriate without departing from the scope of the disclosed concept. For example, the automatic registration and color adjustment device may determine that an affected plate cylinder 31 or ink fountain 33 should be replaced.

[0044] FIG. 4 is a flow chart for a method 4000 of automatic registration and color adjustment using an automatic registration and color adjustment system according to a non-limiting, example embodiment of the disclosed concept. The automatic registration and color adjustment system is similar to the automatic registration and color adjustment system 10 as described with reference to FIGS. 2-3. The method 4000 may be performed by the automatic registration and color adjustment system 10 or the components thereof.

[0045] At 4010, an automatic registration and color adjustment system is provided. The automatic registration and color adjustment system comprises: (i) a can decorator including a plurality of plate cylinders and a plurality of inking stations, each plate cylinder being associated with an individual inking station; (ii) a plurality of sensors including an ambient temperature sensor structured to sense an ambient temperature associated with the can decorator and a component temperature sensor structured to sense a component temperature associated with one or more components of the can decorator; and (iii) an automatic registration and color adjustment device communicatively coupled to the can decorator and the plurality of sensors and including a memory structured to store previous adjustment information associated with the can decorator.

[0046] At 4020, the automatic registration and color adjustment device receives outputs of the plurality of sensors.

[0047] At 4030, the automatic registration and color adjustment device determines an adjustment to one or more components of the can decorator based on the outputs of the plurality of sensors and the previous adjustment information.

[0048] At 4040, the automatic registration and color adjustment device controls the can decorator to make the determined adjustment.

[0049] While specific embodiments of the invention have been described in detail, it will be appreciated by those skilled in the art that various modifications and alternatives to those details could be developed in light of the overall teachings of the disclosure. Accordingly, the particular arrangements disclosed are meant to be illustrative only and not limiting as to the scope of disclosed concept which is to be given the full breadth of the claims appended and any and all equivalents thereof.
