The present invention relates to a device for imprinting cans, especially aluminum cans having more than one finished art on its surface. The invention also relates to a process for imprinting the respective can, as well as to the can obtained by this imprinting process.
Currently, packaging cans of drinks or liquids have impressions on their outer surface, mainly due to the fact that the contents of the can have to be communicated to the consumer because there is a market need related to the printing in different colors.
The most common printing type performed on the cans is the dry rotary offset-type which is made by a specific printer for this purpose.
This type of printing enables one to apply a plurality of colors onto the cans that are metallic, preferably, made of either aluminum or steel. Such an imprinting is carried out on cans during their manufacturing process, which consists of a sequence of cutting, mechanical shaping, the imprinting itself and subsequent shaping, until the can reaches its final desired shape to receive the liquid contents and corresponding closure.
Of course, the steps to which the cans are submitted in the manufacture process will not be described in the present specification, since the object of the invention in question is directed to the imprinting itself.
In any event, an imprinting device or a printer, as it is usually known, can be seen in
The device 1 of
Thus, it is necessary for the imprinting device to be provided with an ink cartridge 2a-2f for each of the colors that one wishes to apply onto the cans, i.e., if a can is to be printed with three colors, namely black, red and white, three of the six ink-cartridge 2a-2f should be supplied with the necessary dye. It should be noted that in this type of equipment there is a limitation of the number of colors to be applied to the can imprinting that is linked to the number of ink-cartridge available. In other words, if there is interest in imprinting, for instance, ten different colors onto the can, it is necessary that the imprinting device should have at least ten ink-holders 2a-2f.
The ink-holders 2a-2h in turn, supply ink to transferring or printing plates 3a-3f which have the finished art to be imprinted onto the can. This finished art may be a text, a figure or any type of graphic which one wishes to make on a can, wherein it is of the utmost importance to position the printing plate correctly, so that it receives the ink from the ink-cartridge. For this purpose, the printing plate, for example, 3a, which is generally produced from a magnetic material, has a precise alignment on the plate cylinder 4a.
This alignment is achieved from the guide-bores existing in the printing plate (not shown in the Figure), which are aligned to guide-pins on the plate cylinder 4; which in turn is formed by a substantially cylindrical body, on which the printing plate involves its outer surface in an aligned and well-fixed manner. This is possible because the outer surface of the plate cylinder is formed by magnets that attract said printing plate 3a and keep it in the desired position.
It is also important to point out that the finished art present on the printing plate 4a is in relief, so that it transfers the ink supplied by the ink cartridge 2a to a transfer blanket 5a. This transfer blanket 5a is an ink transferring means between the printing plate 3a and the can to be imprinted.
Thus, the relief on the printing plate 3a that has the finished art comes into contact with the transfer blankets; thus transferring only the ink that is present thereon to said transfer blanket 5a. This is carried out by rotation of the printing plate 3; which transfers the ink present in relief to the transfer blankets; which is fixed on the transfer blanket drum 6, which is a device with rotation synchronized with (i) the cans to be imprinted, (ii) the positioning of the transfer blankets 5a-5l that are on the surface of such a transfer blanket drum 6, and (iii) the printing plates 3a-3f.
Indeed, if there is synchronization between these elements, it is possible that the cans will be imprinted in a quite precise manner. This is of the utmost importance for can imprinting, since there is no overlapping of the imprint on the can when it receives more than one finished art on its surface. In other words, the finished art of a first printing plate 3a will transfer ink only to a determined area of the transfer blankets 5a-5l, whereby a second printing plate 3b-3f will transfer ink present only on its surface to another area that did not receive ink from the first printing plate 3; and so on. Of course, this depends on the number of imprinting colors on the cans.
Thus, there is the possibility of imprinting the whole can surface, without occurring ink overlapping, which would impair the imprint on the can in this type of rotary dry offset imprinting, since such overlapping would cause an imprinting defect, for example stain.
In this regard, it should be stressed that there is transfer of more than one finished art with a different color to one or more than one transfer blanket 5a-5l present on the transfer blanket drum 6 from the respective printing plates 3a-3f that are in communication with the respective ink-cartridges. Hence, upon continuous rotation of the transfer blanket drum, the latter comes into contact with the cans to be imprinted from the transfer blankets positioned there.
It is reiterated that each of the transfer blankets 5a-5l can receive, on its surface, a plurality of different colors coming from more than one printing plate 3a-3f but the transfer blankets 5a-5l do not have any over-lapping of finished art with different colors.
The cans to be imprinted may even be colorful, but when they are examined in detail one can see that with this type of imprinting there is no color overlapping. Despite the proximity of the different colors that are on the can surface, there will always be a small space between the imprinting of different colors.
It is also important to note that, when one wishes to change the finished art present on the cans that are being imprinted, it is necessary to interrupt the production, that is, the imprinting device 1 should necessarily be stopped, and so it cannot make the imprint the cans any longer. Such stoppage is necessary, because there may be the need to change the printing color of the can, or to change a can for a different product. For example, when one is carrying out a type of can imprinting and wishes to change the finished art present on the cans, it is necessary to interrupt the imprinting process. In short, with the existing process and equipment, it is only possible to achieve one type of finished art printed on the can with the same imprinting device. If it is necessary to change the imprint on the can, the production will necessarily have to be interrupted, which for economical reason should be minimized as much as possible.
This can be easily observed through the order or magnitude of can imprinting, which is very significant. With the present-day pieces of equipment, one can imprint approximately 2.5 million cans in a single day.
Thus, at present there are a number of studies with a view to minimize, as much as possible, the stoppages of this type of equipment, so that the production will not be interrupted. It is noted that these stoppages are, as a rule, compulsory, because the same production line is intended for cans with the most varied finished arts, as for example, a can intended for beer or soft drinks.
In turn, in the face of the significant amount of production of cans and the substantial imprinting speed, the cans that have been imprinted are packed for delivery to clients of the can manufacturers. Then, as an example, when there is production of a given type of can, the produced cans are packed in pallets, wherein each of the pallets have about 6,000-15,000 units of imprinted cans, and all of them with the same imprint, that is, with the same finished art printed on them.
Thus, the client of the can manufacturers, mainly companies that produce beverages, receive loadings of pallets with an expressive number of cans, which follow the production line of this type of company which will fill the can beverages and deliver them to wholesalers, as for example, supermarkets. In other words, the supermarkets will also receive a large number of cans with beverages having the same finished art imprinted thereon.
In order to show an example of this, one can see in
However, as said before, the same sequence of production of cans has necessarily the same imprint arrangement, that is, the cans are virtually identical.
If there is the intention to make cans with different imprint arrangements, it is necessary, in the prior art, to interrupt the production line in order to change the printing plates 3a-3f.
In this regard, it is reminded that the beverage market is greatly influenced by the marketing of the companies of such segment. Thus, the imprint arrangements or finished arts on the cans are considered extremely important to such companies. This is because the consumer is often influenced to buy a given product by the visual aspect brought by the imprint on the cans.
This influence in the decision of the consumer has put more and more pressure on the marketing sectors of the beverage companies, since they require the launching of new and different imprint arrangements. However, in spite of the effort in these sectors, the professionals acting in this segment have significant limitation in their creation, namely due to the fact that the same type of beverage can produced in the same series (in the production of the can or in the packing of the product) necessarily always has the same finished art. This is not related to the limitation of the professionals involved in the creation of the layout or imprint arrangement of the cans, but to the fact that the same production in series and without interruption necessarily has the same imprint.
The present invention is provided to solve the problems discussed above and other problems, and to provide advantages and aspects not provided by prior apparatuses of this type. A full discussion of the features and advantages of the present invention is deferred to the following detailed description, which proceeds with reference to the accompanying drawings.
The invention in question relates to a can imprinting device that has a number of ink-cartridges depending on the need for colors to be printed onto the cans. These ink-cartridges supply ink to a number of printing plates that have finished arts that will impart the shapes and colorful imprint arrangements to the cans.
Such printing plates having finished arts are fixed to respective plate cylinders, so as to communicate with transfer blankets fixed to a transfer blanket drum to supply ink, whereby this ink comes from the ink-cartridges.
Thus, the transfer blankets arc, in turn, moved to transfer ink from the ink-cartridges to the cans, each of the transfer blankets having respective finished arts in low relief and free from ink from the ink-holders.
Moreover, it is also an objective of the invention to provide a process for the production of cans that use the above-described imprinting device. The steps of this process are: (i) supplying ink from the ink-holders to the printing plates present on the respective plate cylinders; (ii) supplying ink from the printing plates to transfer blankets by rotation of the printing plates; (iii) transferring ink from the transfer blankets to the cans; and (iv) forming finished arts of low relief present in the transfer blankets on the cans.
Other features and advantages of the invention will be apparent from the following specification taken in conjunction with the following drawings.
To understand the present invention, it will now be described by way of example, with reference to the accompanying drawings in which:
While this invention is susceptible of embodiments in many different forms, there is shown in the drawings and will herein be described in detail preferred embodiments of the invention with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the broad aspect of the invention to the embodiments illustrated.
The object of
In this way, it is possible to obtain, at the end of the can production line, pallets with different finished arts or imprint arrangements, i.e., instead of having the same sequence of can production with equal imprints, it is possible to have cans with different imprint arrangements, which has a substantially significant commercial effect. This is because it is possible for the same commercial establishment to receive cans containing, for example, the same product, but in cans which are different from each other.
This becomes very important because there is the possibility of a wide range of different creations for the marketing sectors of the companies that produce beverages. Thus, for instance, if there is a determined promotion or festivity of great magnitude, the object of the present invention enables the production of cans from the same production series, i.e. sequentially and continuously manufactured, to have different imprint arrangements, as for example cartoons, animal drawings, person names, country names, or still of sports activities. In short, the imprint arrangements or finished arts may be of different kinds and depend basically on the respective creativity of the creator of cans, since in light of the present invention there is no longer any technical limit that requires the interruption of imprinting to provide cans with different imprint arrangements or finished arts from the same uninterrupted sequence of production.
The imprinting device 1 can be observed in greater detail in
On the can indexer 11, the cans are then displaced in a circle around said indexer 11. Although the cans 8 are retained in the can chain 7, they still have the possibility of turning around their main axis, i.e. a central longitudinal axis about which the can is formed.
In the right portion of
In
However, the ink-cartridges 2a-2h do not rest on the transfer blanket drum 6, since between each ink cartridge 2a-2h and the transfer blanket drum 6 there are respective plate cylinders 4a-4h. As mentioned above, on the plate cylinders 4a-4h there are respective printing plates that have the finished arts in relief on their outer surface facing the transfer blanket drum 6.
Moreover, the printing plates 4a-4h are responsible for the communication between the ink-cartridges 2a-2h and the transfer blankets 5a-5l, which are placed on the outer surface of the transfer blanket drum 6. Obviously, there should be a positioning/interaction between the printing plates 4a-4h and the transfer blankets 5a-5l, so that the transfer blankets 5a-5l can interact in a precise manner with the cans 8 to be imprinted.
With a view to exemplify how the interaction between the components responsible for the imprinting takes place,
In
The plate cylinder 4a, upon coming into synchronized contact by the printing plate 3a with the transfer blankets drum 6, supplies ink from its high relief to the transfer blanket 5a, wherein this takes place by rotation of the printing plate that transfers the ink present on high relief to the transfer blanket 5a.
Afterwards, and by opposite directions rotation of the transfer blanket drum 6 and the can indexer 11, the transfer blanket 5a that has the ink from the printing plate 3a transfers the ink present on the transfer blanket 5a to the can 8, which is rotated under some pressure against the transfer blanket 5a.
It is pointed out that, if it is necessary to imprint more than one finished art or different colors onto the can 8, the transfer blanket 5a will also have passed through the other printing plates 3b-3h present on the respective plate cylinders 4b-4h. The same occurs successively with the other transfer blankets 5b-5l that have the finished art coming from any printing plates that are necessary for obtaining all the finished art of different colors on the cans 8 to be imprinted.
Thus, the finished arts present on the printing plates are transferred to the transfer blankets, which in turn transfer ink to the cans 8.
The transfer blankets of the present invention can be seen in
Usually, that is, in the prior art, these transfer blankets are only smooth surfaces that are used as ink transferring means between the printing plates 3a-3h and the cans 8 to be imprinted. However, in the present invention the transfer blankets also have the function of being a graphics mean that has influence on the finished arts of the cans 8 to be imprinted.
In the example of
In the preferred embodiment of the present invention one has opted for using a transfer blanket drum with twelve blankets 5a-5l, but, as mentioned before, only three blankets are shown in
It is of the utmost importance to note that the transfer blankets 5a-5c have respective low reliefs 13a-13c, wherein the low reliefs of finished arts are in reality low relief 13a-13e with different shapes. Therefore, there is a finished art in low relief 13a present on the blanket 5a, a finished art in low relief 13b present on the blanket 5b and another finished art in low relief 13c present on the blanket 5c.
Thus, when there are three types of blankets 5a-5c with different finished arts in low relief it is possible that all the finished arts coming from printing plates will be transferred by ink to the transfer blankets 5a-5e, so that the cans 6 will be imprinted in this way.
However, since each of the finished arts 13a-13c is in low relief, there will be no ink in this low-relief portion of each of the blankets. There will be no contact, in this low-relief region, between the blanket and the cans 8 to be imprinted. Indeed, the original color of the can 8 will remain in this region free from ink or free from contact between the can 8 and the respective blanket that is transferring the ink from the transferring blankets to the can 8.
Therefore, if there is a low-relief finished art 13a on the blanket 5a which, in the present example, a circle, there will be no imprint or ink transfer from this low-relief region to the can 8. Therefore, a first finished art is formed on the can 8, as shown in
Thus, the next can 8 to be imprinted will also receive ink from the printing plates, but from the next blanket. In this example, the transfer blanket 5a has a low-relief finished art 13b in the form of a rectangle. In this way, the can to be imprinted will have a second finished art in the form of a rectangle in the original color of the can.
Following the same logic, a third can to be imprinted will also receive ink from the printing plates, but from a subsequent blanket other than the first two ones. This third transfer blanket 5c has a low-relief finished art 13c in the form of a pentagon, so that the can to be imprinted will have a third finished art in the form of a pentagon in the original color of the can.
As already mentioned, the number of different finished art on the cans will only be limited to the number of blankets present on the blanket drum 6.
It is further stressed that the finished arts present on the blankets—that are portions of removed material of the blankets—are arranged directly on the blankets without any other type of layer on the blanket, so that the latter can have the printing function, i.e., the function of having a finished art that will be present on the imprinted can.
It is reiterated that the low reliefs or portions of material removal will represent absence of ink, which will enable one to view the original color of the can, be it the color of the aluminum or of a coating of other coloring that the can to be imprinted already has.
The finished art produced by the low relief will be a final contour on the imprinted can, which will provide a clearer finished art, and the low relief present on the blanket will have less problems with usual imprinting aspects, such as, for instance, ink stains, smears or any other type of problem related to the high-precision imprinting or detailing.
In
Obviously, the finished arts or graphic arrangements are not limited to geometric shapes, but may be any type of graphic means that one desires to print on the cans 8, as for example, names of persons, of teams, figures, etc. In this regard, the limitation is no longer in the imprinting process, but rather in the creativity of those who develop the finished arts to be applied to the imprinted cans.
In the view of the foregoing, it is possible to have, in the same uninterrupted production line, cans with different finished arts, which was possible only with the interruption of the production line until the advent of the present invention.
However, it was not feasible, in terms of logistics, to obtain cans from the same production sequence with different finished arts on the same pallet, or still delivered to the beverage manufacturers, such as supermarkets. However, this has become possible with the present invention.
According to another embodiment of the present invention, artwork with improved resolution and/or increasing complexity can be generated using transfer blankets 5a-5l with improved, highly detailed low-relief features. In the prior art, the printing plates 3a-3h carry detailed art in high relief as described above. The high relief art is transferred to a transfer blanket 5a-5l which then prints the can 8. As described above, the transfer blankets 5a-5l may be supplied with low relief art wherein the can 8 will have an area devoid of ink corresponding to the low relief art on the transfer blankets 5a-5l. By way of example, under a prior art printing process, printing plate 3a-3h will have a relief feature. To print, for example, “BRAND X SODA” on a can, a printing plate 3a-3h has “BRAND X SODA” in high relief on a surface of the printing plate 3a-3h. Then the ink is applied to the high relief on the surface of the printing plate in the shape of “BRAND X SODA”.
In the present invention, it is contemplated that improved and more flexible high resolution low-relief features can be generated by treating the transfer blankets 5a-5l with a suitable laser beam. In this embodiment, portions of the blanket 5a-5l are removed by laser treatment. Through laser ablation, very different, highly complex and detailed relief patterns can be created on each of the transfer blankets 5a-5l, rather than simple shapes and the like as discussed above.
For example, each blanket 5a-5l is typically produced from a non-metallic material such as a rubber (or a polymer or composite) rectangle the size of a legal paper. Each blanket is typically ⅛ to ¼ inch thick (3.2 mm to 6.4 mm). Shading can be generated by varying the depth and size of the low-relief features. In practice, printed areas on a finished can be made lighter or darker depending on how much of the surface of a particular transfer blanket 5a-5l is removed during the laser treatment process.
Basically, there are two different properties that are essential to the laser treatment discussed herein: tolerance of the cut and surface finish. Standard technology laser cutting equipment that has been in use for 5+ years uses a focused laser beam. The spot size of the laser beam determines the tolerance and the surface finish. Older laser cutting machines that have been in service for 5+ years, have 0.008 to 0.010 inches spot diameter size (0.2 mm to 0.3 mm). Newer laser cutting machines a focus within a spot diameter size of 1-2 thousandths (0.001 to 0.002 inches) of an inch (0.03 mm to 0.05 mm). Generally, using a laser as contemplated by the inventors, a low-relief feature having a surface finish or depth as little as 0.001 inches (0.03 mm) or less can be created.
In creating high resolution low-relief features on a transfer blanket 5a-5l using a laser cutting apparatus, the apparatus must position and move the beam accurately. Because the beam is moving in two dimensions (e.g., an X & Y coordinate system) speed of the laser beam movement must be controlled. For example, if a straight cut is being generated, the laser beam speed across the surface of the transfer blanket needs to be constant. Once a curved cut or low-relief pattern is desired, the speed at which the laser beam travels must be varied so that the laser beam can affect the cut itself. Software and algorithms calculate the proper speed of the laser beam along the surface as cuts are made. Suitable transfer blankets have been manufactured using a 420W Stork® brand laser engraver set at a speed of about 12 m/s. The result is a smooth cut and a smooth surface finish.
To avoid a resultant blurring effect on a finished can caused by the low-relief features produced by laser ablation on the transfer blankets 5a-5l, the surface of the transfer blanket 5a-5l must have a better surface finish, especially, or primarily, an edge of the transfer blanket surface between the low-relief laser ablated surface and an untreated surface. The better the edge surface the laser creates, the better the printed edge of the finished product. This better surface finish will result in a cleaner, crisper image.
Final surface finish of a laser treated transfer blanket 5a-5l is dependent on the transfer blanket 5a-5l thickness prior to laser treatment. A thicker transfer blanket will have a rougher final surface finish. The laser does not cut as smoothly in thicker substrates.
However, depending on the algorithm, the speed, and the arc, smoothness of the laser cut can be improved. When a laser is cutting an arc or intricate shapes, the algorithm will change the speed and how the laser beam is moving. This results in a cleaner shape.
In generating transfer blankets of the present invention, laser beam spot size was generally on the order of 0.003 inches (0.08 mm). However, such a spot size is inadequate for producing cans with high resolution graphics devoid of ink as contemplated herein. More specifically, the inventors determined that transfer blanket low-relief pattern quality suffers when a laser beam spot size greater than 0.002 inches (0.05 mm) is employed. This will result in a target surface finish of about 125 to 250 micro inches (about 0.002 inches or 0.05 mm).
To illustrate this aspect of the invention, referring to
Referring to
Referring to
Further, the corner 66 forming the contour of the rectangle is critical in establishing the high level of graphic quality discussed hereinafter. A surface finish of the transition between an upper surface of a blanket 5 on which ink is deposited by a printing plate 3 (high relief portion) and the recessed portion of the blanket 5 (low relief portion) is less than or equal to 3.5 Ra, preferably less than 3.5 Ra, and more preferably 3.0 Ra±0.1 Ra. Additionally, the most preferable surface finish in this region has 3.33 Rmax. Adequate blankets have been manufactured having a surface finish of about 3.03 Ra.
In zone C, the rectangle floor's surface finish is a function of laser technology and blanket material. A target of 125 to 250 micro inches (about 0.002 inches or 0.05 mm) for the surface finish is preferred to achieve desired results. Suitable blankets having a surface roughness of 3.03 Ra (3.33 Rmax) have been produced having a floor depth of about 0.015 inches (0.38 mm). It has been determined that the floor depth of about 0.015 inches (0.38 mm) performs well in that ink is not transferred from the low relief floor to the beverage container 8 when the floor is at least 0.015 inches (0.38 mm).
More particularly to
According to the invention, finished art may be delivered to each container in a sequence of continuously, individually decorated beverage cans. Printing plates may be provided to indirectly deliver (via transfer blankets) identical finished art to each beverage can in a sequence. Individual transfer blankets may have high and low relief features to deliver unique art to each beverage can in the sequence, such that two or more adjacent beverage cans in a sequence of decorated beverage cans may each exhibit some identical decorations or art (originating from the printing plates) and some unique art (originating from the transfer blankets).
According to an embodiment of the invention and further to the features described above, a can imprinting apparatus 1 has a plurality of ink cartridges 2a-2h, preferably each of a different color. A plurality of printing plates 3a-3h are rotationally mounted on the apparatus 1, preferably as described above. Each printing plate 3a-3h is in communication with a corresponding ink cartridge of the plurality of ink cartridges 2a-2h and has a finished art in high relief. A first printing plate in the plurality of printing plates 3a-3h has a first finished art comprising a high relief portion of the first printing plate. This high relief portion comprises a portion of an upper surface of the first printing plate and is adapted to receive an ink from one of the plurality of ink cartridges.
The apparatus 1 further has a plurality of transfer blankets 5a-5l. The plurality of transfer blankets 5a-5l are rotationally mounted to the apparatus such that each transfer blanket rotates about a single central hub or axel. A first transfer blanket has a plurality of low relief features and a plurality of high relief features on an upper surface thereof. The plurality of low relief features cooperate with the plurality of high relief features to form a second finished art comprising a first character. The first character includes a shading pattern to simulate depth and contour. A second transfer blanket also has a plurality of low relief features and a plurality of high relief features on an upper surface thereof. These plurality of low relief features cooperate with the plurality of high relief features to form a third finished art comprising a second character. The second character includes a shading pattern to simulate depth and contour which is unique relative to the first character on the first transfer blanket. The high relief features on the first and second transfer blankets are engageable with the first printing plate and receive a supply of ink therefrom.
The apparatus 1 also includes a can indexer 11. The can indexer is rotationally mounted to the apparatus 1 and has a plurality of stations for receiving cans 8 therein. The can indexer 11 rotationally delivers a plurality of cans 8 sequentially and continuously to a printing site 15 where a first can 8 engages the first blanket and receives ink therefrom at the printing site 15. The can indexer 11 transfers the first can 8 from the printing site 15 while simultaneously transferring a second can 8 to the printing site 15 wherein the second can 8 engages the second blanket and receives ink therefrom.
