Abstract
Card processing mechanisms and methods whereby after a card has been processed on one surface thereof at a card processing station such as, but not limited to, a card printing mechanism, the card can be recirculated back upstream of the card processing station along a return card travel path that is separate from the primary card travel path through the card processing station where the card can then be reintroduced back into the primary card travel path and transported through the card processing station a second time. As the card is being returned along the return card travel path, the card can be flipped over so that when the card is transported back through the card processing station, the opposite surface of the card can be processed.

DETAILED DESCRIPTION
(6)
(7) In the example illustrated in
(8) The mechanisms 14, 16, 18 can be arranged in any order in the system 10. In addition, not all of the mechanisms 14, 16, 18 need to be utilized. For example, in one embodiment, the mechanism 16 can be used by itself without the other mechanisms 14, 18. In addition, additional card processing mechanisms can be utilized with the mechanisms 14, 16, 18.
(9) The card feed mechanism 12 feeds cards to be processed by the system 10 onto a card processing path 22 at up to a first card rate. The card rate of the feed mechanism 12 refers to how fast the mechanism 12 can feed cards one by one into the processing path 22. In one embodiment, the first card rate can be up to about 3000 cards per hour. The card feed mechanism 12 can include one or more card hoppers containing cards waiting to be fed one-by-one onto the card processing path 22.
(10) The card processing mechanism 16 is disposed on and along the card processing path 22 to receive cards. The card processing mechanism 16 is configured to perform a processing operation on each card. In one embodiment, the card processing mechanism 16 is configured to perform printing. Examples of printing include drop-on-demand printing with a UV curable ink, printing using a thermal dye transfer ribbon, retransfer printing, laser marking using a laser, and other card printing techniques.
(11) As discussed in further detail below with respect to
(12) Returning to
(13) In the embodiment illustrated in
(14) The embodiment illustrated in
(15) Cards that have been processed are collected in the card output 20 that is disposed along the card processing path 22 downstream of the card processing mechanism 16. The processed cards can then be distributed to their intended recipients, for example by attaching the cards to mailer forms and mailing to the intended recipients.
(16) Many other card processing mechanisms can be used in addition to, or in place of, the processing mechanisms illustrated in
(17) Referring now to
(18) The mechanism 16 includes the at least one print station 26 on the primary card travel path 24 that performs a printing operation on surface A or B of each card 30 on the primary card travel path 24. The print station 26 can include a plurality of print heads 27 (shown in
(19) The return card travel path 28 intersects the primary card travel path 24 both downstream of and upstream of the print station 26. The return card travel path 28 is configured to divert or recirculate a card that has been fed through the print station 26 from the primary card travel path 24 and return the card back to the primary card travel path 24 at a location upstream of the print station 26 so that the card can again be fed through the print station 26. In addition, in some embodiments, as the card is being recirculated along the return card travel path 28, the card can be flipped 180 degrees so that the surface A or B that was previously printed on is now facing downward and the non-printed surface A or B is facing upward ready to be printed on.
(20) The return card travel path 28 can have any configuration and location that is suitable for recirculating the cards upstream of the print station 26 so they can fed through the print station 26 a second time, or even more than two times. The card return travel path 28 can have any general shape as long as it functions to efficiently return cards to the primary card travel path 24 upstream of the print station for a second pass through the print station 26. In some embodiments, the return card travel path 28 can be on substantially the same plane as the primary card path 24. Alternatively, the return card travel path 28 can be located on a plane that is above or below the plane of the primary card travel path 24. In addition, the return card travel path 28 can be substantially linear or it can be curved. In addition, any mechanism(s) for selectively recirculating the cards along the return card travel path 28 and optionally flipping the cards 180 degrees can be used.
(21) For example, in the embodiment illustrated in
(22) The mechanisms 36, 40 can have any configuration that can suitably transport the cards between the primary card travel path 24 and the portion 28a of the return card travel path 28. For example, as discussed further below in
(23) In other embodiments, the mechanisms 36, 40 can be elevator mechanisms that transport the cards between the card travel paths. An example of a card elevator mechanism is disclosed in U.S. Pat. No. 6,105,493 the entire contents of which are incorporated herein by reference. In other embodiments, a sequence of card flippers can be used to transport cards between the card travel paths. Examples of card flippers are disclosed in U.S. Published Application No. 2013/0220984 and U.S. Pat. No. 7,398,972 the entire contents of each are incorporated herein by reference.
(24) Referring to
(25)
(26)
(27) Once a card reaches the mechanism 36, if no further printing is required on the card, the card can be advanced through the mechanism 36 and out of the mechanism 16. At the same time, if a card is advanced out of the mechanism 16, a new card can be transported into the mechanism 16 via the mechanism 40 to begin the process of printing on a surface of the new card. After a surface of the new card is printed, it can be recirculated back upstream of the print station 26 along the return card travel path 28 and flipped so that the other side of the new card faces upward, so that printing can occur on the other side of the new card.
(28) If printing on both sides A and B of the card is not required, the card can be passed a single time through the print station 26 and then output from the mechanism 16 without recirculating the card through the return card travel path 28.
(29) A method of processing cards in the card processing system 10 that results from the example system 10 and the example sequencing illustrated in
(30) As is apparent from
(31) With drop-on-demand printing, it is preferable that the card being printed on in the print station 26 is oriented such that the card is oriented substantially flat or horizontal relative to the ground. However, in some card processing systems, cards may be transported along the card processing path 22 in a second orientation where the cards are oriented substantially vertically relative to the ground. Therefore, in such an embodiment, upon reaching the mechanism 16, the cards need to be reoriented by rotating the cards 90 degrees, for example from a vertical orientation to a horizontal orientation, and upon exiting the mechanism 16, the cards may need to be reoriented by rotating the cards 90 degrees, for example from the horizontal orientation back to the vertical orientation.
(32)
(33) The cards can initially enter the mechanism 16 into an optional input roller mechanism 50. The mechanism 50 can rotate about a vertical axis A-A. The mechanism 50 is useful for, if necessary, flipping the cards about the axis A-A so that if side A of a card is facing forward upon entry into the mechanism 16, the mechanism 50 can rotate the card so that side B faces forward. If flipping of a card is not required, the card can simply pass through the mechanism 50 without being flipped about the axis A-A.
(34) Each vertically oriented card is then fed into a first rotation mechanism 52. The rotation mechanism 52 is configured to receive each card, and then rotate in either direction about an axis that is substantially parallel to the primary card travel path 24 to rotate the card from its vertical orientation to a horizontal orientation that is aligned with the primary card travel path 24. The now horizontal card can then be transported from the mechanism 52 and onto the primary card travel path 24. The mechanism 52 can rotate 90 degrees in either direction to bring the now horizontal card into alignment with the primary card travel path 24. The mechanism 52 is also configured to receive a card from the portion 28b of the return card travel path 28 and rotate 180 degrees along with the card about the axis that is substantially parallel to the primary card travel path 24 to bring the card back to the primary card travel path 24.
(35) The now horizontal card is then transported past the print head(s) 27 of the print station 26 for printing on whichever surface is facing upwardly toward the print head(s) 27. Once printing is complete, the card is fed into the UV curing station 34. After curing, the card is fed into a second rotation mechanism 54 near the output of the mechanism 16. The rotation mechanism 54 is configured to receive each card, and then rotate in either direction about an axis that is substantially parallel to the primary card travel path 24 to transport the horizontally oriented card from the primary card travel path 24 to the portion 28b of the return card travel path 28. In one embodiment, the rotation mechanism 54 rotates 180 degrees to transport the card from the primary card travel path 24 to the portion 28b of the return card travel path 28 with the card still in its horizontal orientation. The card can then be transported along the portion 28b of the card travel path 28 to the flipper 38 which can flip the card (if necessary) so that the appropriate side faces upward. The card is then transported into the first rotation mechanism 52 which rotates to transport the can back to the primary card travel path 24.
(36) An optional output roller mechanism 56 can be provided adjacent to the output of the mechanism 16. The mechanism 56 is similar in construction and operation to the mechanism 50 in that the mechanism 56 can rotate about a vertical axis A-A. The mechanism 56 is useful for, if necessary, flipping the cards about the axis A-A so that if side A of a card is facing forward as it is about the exit the mechanism 16, the mechanism 56 can rotate the card so that side B faces forward. If flipping of a card is not required, the card can simply pass through the mechanism 56 without being flipped about the axis A-A.
(37) The techniques described herein can be used with printing other than drop-on-demand printing. For example, in the case of thermal dye diffusion printing, if printing is required on both sides A and B of the card, the card can be recirculated back to the thermal dye diffusion printhead. In the case of thermal dye diffusion printing, the stations 32, 34 in
(38) The cards can be transported along the primary card travel path 24 and the portion 28b of the return card travel path 28, as well as along the card processing path 22 through the mechanisms 14, 18 using any card transport mechanisms that are well understood by people of ordinary skill in the art. For example, the cards can be transported using rollers, belts, and combinations thereof.
(39) The mechanisms 12, 14 and 18 have been described as having card rates approximately equal to one another (for example each up to about 300 cards per hour), and the mechanism 16 has been described as having a card rate (for example up to about 6000 cards per hour or even greater) that is greater than the card rates of the mechanisms 12, 14, 18. However, the mechanisms 12, 14, 16 and 18 can have card rates that are approximately equal to one another.
(40) The examples disclosed in this application are to be considered in all respects as illustrative and not limitative. The scope of the invention is indicated by the appended claims rather than by the foregoing description; and all changes which come within the meaning and range of equivalency of the claims are intended to be embraced therein.
