Abstract

The present invention discloses a re-transfer printing card machine capable of excluding overlapping card insertion and its control method. The re-transfer printing card machine capable of excluding overlapping card insertion includes a card supply unit (2), a card cleaning unit (3), a card flipping unit (4), a record electronic information unit, a ribbon transmission unit (8), a transfer film transmission unit (9), a printing unit (10), a transfer unit (11), a card flattening mechanism (12), a completed card storage slot (13), and a failed card storage slot (14). During the process of card insertion, it can be determined whether there is overlapping card insertion, and by judging the total length of the overlapping card insertion, it can be determined whether to allow the cards with overlapping card insertion to be discharged into the failed card storage slot or to discharge the cards into the card collection box.

Description

Technical Field

[0001] The invention relates to a card printing machine, and in particular to a re-transfer card printing machine capable of eliminating overlapping card feeding and a control method thereof. Background Art

[0002] The retransfer card machine is a machine used to make credit cards, bank cards, and membership cards. The printing medium of the retransfer card machine is cards. The thickness of the cards is generally 0.3mm~2mm. Most of the common ones are 0.3mm (about 10mil.), 0.5mm (about 20mil.), 0.76mm (about 30mil.), and 1.0mm (about 40mil.). In order to cope with the above different card thicknesses, the card supply unit generally has a Go-No-Go mechanism to screen cards of specific thickness and ensure that the cards can enter the machine one at a time. Even so, there is still a chance that more than two cards will overlap and enter the card at the same time. The serious malfunction is usually caused by overlapping cards that are staggered and overlapped in the direction of card movement. When the overlapping cards in the above situation enter the machine, it will most likely cause a machine jam.

[0003] Therefore, how to design a re-transfer card machine and a control method thereof that can detect the overlapping card feeding state and automatically eliminate the overlapping cards is a technical problem that needs to be solved urgently in the industry. Summary of the invention

[0004] In order to solve the above defects in the prior art, the present invention provides a re-transfer card machine and a control method thereof which can eliminate overlapping card feeding.

[0005] The technical solution adopted by the present invention is to design a re-transfer printing card machine capable of excluding overlapping card feeding, which includes a printer bracket 1, and a card supply unit 2, a card cleaning unit 3, a card flipping unit 4, a record electronic information unit, a ribbon transmission unit 8, a transfer film transmission unit 9, a printing unit 10, a transfer unit 11, a card flattening mechanism 12, a completed card receiving slot 13, and a failed card receiving slot 14 installed thereon. Among them, the card supply unit is used to supply and stack blank cards to be printed; the card cleaning unit is used to clean the surface of the blank cards entering the card flipping unit; the card flipping unit can parallelly transfer the cards sent by the card supply unit to the transfer plane, or send the other side of the card for transfer through flipping to achieve double-sided transfer, and can also distribute the cards to the record electronic information unit through flipping; the record electronic information unit records the information on the cards and judges whether the cards are failed cards. If they are failed cards, they are discharged into the failed card receiving slot; the ribbon transmission unit provides a ribbon to the printing unit; the transfer film transmission unit provides a transfer film to the printing unit and the transfer unit; the printing unit orderly prints the dyes on the ribbon onto the transfer film to form an image; the transfer unit transfers the image on the transfer film onto the surface of the card; the card flattening mechanism flattens and corrects the cards passing through the transfer unit; the completed card receiving slot is used to collect the printed cards and failed cards; the failed card receiving slot is connected to the record electronic information unit to collect failed cards or cards with the transfer instruction cancelled.

[0006] The card supply unit 2 includes a spare card storage box 16 and a card capture roller 15. The wheel surface of the card capture roller 15 is rubber with a high friction coefficient. The card capture roller 15 is installed on the printer bracket 1 and is close to the bottom of the spare card storage box. The spare card storage box 16 is used to place cards.

The side wall of the spare card storage box 16 is provided with guide ribs on the outside, and the printer bracket 1 is provided with a track groove. The spare card storage box 16 can slide in and out of the printer bracket 1 along the track groove. A window is provided at the bottom of the spare card storage box. The card capture roller contacts the bottom card in the spare card storage box through the window, and uses the weight of the card to make the card and the card capture roller contact each other. The roller 15 generates friction, and when the card capture roller rolls, it can bring the card in contact with its wheel surface out of the spare card storage box and transport it to the card flipping part. A card thickness selection paddle 161 is provided on the end surface of the spare card storage box facing the card flipping part. The card thickness screening paddle includes a cam plate 161a and a handle 161b. The center of the cam plate is fixed to the side wall of the end surface of the spare card storage box through a rotating shaft 161c. The cam plate can be rotated by turning the handle. The cam plate has four cam surfaces with different radii around the rotating shaft. When a cam surface of the card thickness selection paddle 161 is rotated to face directly below the spare card storage box 16, the distance between the cam surface and the wheel surface of the card capture roller 15 is slightly larger than the card thickness set by the card thickness selection paddle 161 to be allowed to pass.

The magnetic stripe information recording plane 29 forms an angle of approximately 120 degrees with the transfer plane 17. A flip sensor DSD is provided between the card flipping unit 4 and the magnetic stripe information recording unit 5. When magnetic stripe information needs to be recorded on the card, the turntable 22 of the card flipping unit flips the card to the magnetic stripe information recording plane 29. After the card is sent out from the turntable 22 of the card flipping unit, when the leading edge of the advancing card is detected by the flip sensor DSD, the contact head 501 in the magnetic stripe information recording unit records or reads the magnetic stripe information on the card; the contact chip information recording unit 6 is located on the side diagonally below the card flipping unit 4 and away from the card cleaning unit 3. The card handling path plane of the contact chip information recording unit 6 is the contact chip information recording plane 30. The contact chip information recording plane 30 passes through the rotation axis 23 of the flipper. The contact chip information recording plane 30 forms an angle of 30 degrees with the transfer plane 17. A flip sensor ESE is provided between the card flipping unit 4 and the contact chip information recording unit 6. When chip information needs to be recorded on the card, the turntable 22 of the card flipping unit flips the card to the contact chip information recording plane 30. After the card is sent out from the turntable 22 of the card flipping unit, when the leading edge of the advancing card is detected by the flip sensor ESE, the chip reading head 601 in the contact chip information recording unit records or reads the chip information on the card; the radio frequency chip information recording unit 7 is located below the transfer plane 17 above the contact chip information recording unit 6.

[0010] The ribbon conveying unit 8 is located below the card flipping unit 4 and between the angles of the magnetic stripe information recording plane 29 and the contact chip information recording plane 30. The ribbon conveying unit 8 includes a ribbon supply shaft 32 and a ribbon recovery shaft 33, which are respectively driven by a digital controller through a motor.

[0011] The printing unit 10 includes a thermal print head 40, which is located within the area surrounded by the ribbon transfer path 34 of the ribbon transfer unit 8, and the plane where the heating wires on the thermal print head 40 are located faces the transfer film transfer unit 9; the printing roller swing bracket 41 of the printing unit 10 is located within the area surrounded by the transfer film transfer path 38.

[0013] The present invention discloses a control method for a re-transfer ID card printer. The re-transfer ID card printer uses the above-mentioned re-transfer ID card printer capable of excluding overlapping card feeding. The control method includes determining whether to discharge the overlapping card into the failed card storage slot or the completed card storage slot according to the length of the overlapping card detected by the card feeding sensor SA, the flip sensor SB, and the flip sensor SC; when the flip sensor SB and the flip sensor SC detect an overlapping card, the card flip unit 4 transports the overlapping card to the record electronic information unit and discharges it into the failed card storage slot through the record electronic information unit; when the card feeding sensor SA, the flip sensor SB, and the flip sensor SC detect an overlapping card, the card flip unit 4 transports the overlapping card to the transfer unit and discharges it into the completed card storage slot through the transfer unit.

[0014] After the card feeding sensor SA detects that the leading edge of the card enters the card cleaning section 3, the active cleaning roller 24 with a known diameter D and the passive cleaning roller 25 take over to transport the card forward. When the leading edge of the card is detected by the flipping sensor SB, at this time, the active cleaning roller 24 is driven by the digital controller through the stepping motor, and the digital controller starts to count until the trailing edge of the card is detected by the card feeding sensor SA, and records the rotation angle N of the stepping motor driving the active cleaning roller 24 during this period. COUNT , the preset distance L between the card feeding sensor SA and the flipping sensor SB AB , calculate the calculated length L of the card according to formula 1 COUNT ;

[0015] L COUNT = L AB + πDN COUNT / 360 (Formula 1)

[0016] Compare L COUNT with the standard card length L, and preset the distance L between the flipping sensor SB and the flipping sensor SC BC ;

[0017] When L - 1mm < L COUNT < L + 1mm, the card entering the card flipping section 4 is a normal single card and can continue the subsequent information recording or transfer operation;

[0018] When L + 1mm < L COUNT < L BC - 1mm, the card entering the card flipping section 4 is an overlapping card with a total length less than the distance L between the flipping sensor SB and the flipping sensor SC BC , and the card flipping section 4 is flipped to the magnetic stripe information recording plane 29, and the overlapping card is discharged into the failed card receiving slot 14 through the magnetic stripe information recording section 5;

[0019] When L BC - 1mm < L COUNT when, the card entering the card flipping section 4 is an overlapping card with a total length greater than the distance L between the flipping sensor SB and the flipping sensor SC BC - 1mm, and the card flipping section 4 directly sends the overlapping card to the transfer section 11 and discharges it into the completed card receiving slot 13 through the card flattening mechanism 12.

[0020] The beneficial effects of the technical solution provided by the present invention are:

[0021] During the process of card feeding in the present invention, it is possible to determine whether there is overlapping card feeding, and by judging the total length of the overlapping card feeding, it can be determined whether to allow the cards with overlapping card feeding to be discharged into the failed card storage slot or to discharge the cards into the card collection box. There is no need for manual troubleshooting caused by overlapping card feeding, avoiding the need to stop the printing operation and wait for troubleshooting due to overlapping card feeding, which can improve the working efficiency of the re-transfer card printing machine; at the same time, it has the advantages of not increasing material costs, having a compact structure, and being convenient to operate.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0028] The general principle of the present invention is that a strip-shaped ribbon and a strip-shaped transfer film are tightly pressed between a thermal print head and a rubber roller. The ribbon is a strip-shaped plastic base film with a dye coated on one side, and the dye can be printed onto the receiving layer of the transfer film through heating and pressing. The transfer film is a strip-shaped plastic base film coated with a receiving layer that can receive the dye. The receiving layer transfers to the card surface by heating, pressing and an appropriate peeling angle, leaving the plastic base film. The digitally controlled thermal print head orderly prints the dye on the ribbon onto the transfer film to form an image. Subsequently, the above-mentioned transfer film with the printed image and the card are tightly pressed between a heating roller and another rubber roller for heating and pressing, and the image on the transfer film is transferred onto the card surface.

[0029] The present invention discloses a re-transfer card printing machine capable of eliminating overlapping card feeding.

The active cleaning roller 24 and the passive cleaning roller 25 are parallel to each other in axis. There is a spring force between the active cleaning roller 24 and the passive cleaning roller 25 to pressurize their wheel surfaces against each other. The junction of the two wheel surfaces is a card cleaning plane, and the card cleaning plane coincides with the transfer plane 17. The active cleaning roller 24 is connected to the stepping motor through a power mechanism, and the digital controller drives the active cleaning roller 24 to rotate through the stepping motor. The card cleaning unit 3 includes a dust collecting rubber wheel 26 and a dust collecting rubber wheel bracket 27. The dust collecting rubber wheel 26 is covered with double-sided adhesive, and the double-sided adhesive is used to stick the attachments stuck on the card by the active cleaning roller.

[0033] See also Figure 2 In the preferred embodiment shown, the card flattening mechanism 12 is disposed between the transfer unit 11 and the finished card receiving slot 13. When only one-sided transfer is required, the card undergoes a pressurized heating process in the transfer unit 11. Since only one side of the card is heated during the transfer, the two sides are heated unevenly. If the card is directly discharged, the cooled card will bend toward the overheated side. The present invention uses the card flattening mechanism 12 to straighten the bent card when the card is still warm. The card leveling mechanism 12 is located on the side of the transfer section 11 in the horizontal direction away from the card feeding section 2, and includes a first leveling mechanism active roller 54 and a second leveling mechanism active roller 55. The two active rollers are horizontally arranged and assembled on the printer bracket 1 and are located below the transfer plane 17. Both active rollers are driven by the digital controller through a stepper motor. Above the transfer plane 17, there is a leveling mechanism bracket 60 assembled on the printer bracket 1. At the positions where the first and second leveling mechanism active rollers 54 and 55 are mirrored by the transfer plane 17, there are first leveling mechanism idler wheels 56 and second leveling mechanism idler wheels 57 assembled respectively. A leveling spring 59 is installed in the sliding groove on the leveling mechanism bracket 60 to provide clamping force for the two idle wheels and the first and second leveling mechanism active rollers 54 and 55 to clamp the card; above the leveling mechanism bracket 60, there is a leveling mechanism cam 61 driven by a digital controller through a motor, and the wheel surface of the leveling mechanism cam 61 contacts the leveling mechanism bracket 60 to control the up and down swinging position of the leveling mechanism bracket 60. A leveling roller 58 is arranged on the leveling mechanism bracket 60 and between the first and second leveling mechanism idle wheels, and the axis of the leveling roller 58 passes through the fixing hole of the leveling mechanism bracket 60 and can rotate freely.

The magnetic stripe information recording plane 29 forms an angle of about 120 degrees with the transfer plane 17. A flip sensor DSD is provided between the card flipping unit 4 and the magnetic stripe information recording unit 5. When magnetic stripe information needs to be recorded on the card, the turntable 22 of the card flipping unit flips the card to the magnetic stripe information recording plane 29. After the card is sent out from the turntable 22 of the card flipping unit, when the leading edge of the advancing card is confirmed by the flip sensor DSD to enter the magnetic stripe information recording unit 5, the distance between the leading edge of the card and the magnetic head 501 is calculated. When the leading edge of the card contacts the magnetic head 501, magnetic stripe information recording or reading starts.

[0036] The contact chip information recording unit 6 is located on the side diagonally below the card flipping unit 4 and away from the card cleaning unit 3. The card transport path plane of the contact chip information recording unit 6 is the contact chip information recording plane 30.

The distance between the flip sensor SE and the rotation axis 23 of the flipper is greater than the distance between the flip sensor SB and the rotation axis 23 of the flipper, so that the card will not touch the flip sensor SE when the turntable 22 of the card flipping unit flips. When chip information needs to be recorded on the card, the turntable 22 of the card flipping unit flips the card to the contact chip information recording plane 30. After the card is sent out from the turntable 22 of the card flipping unit, when the leading edge of the advancing card is detected by the flip sensor SE, the sensor confirms that the card enters the contact chip information recording unit 6 and starts to calculate the distance between the leading edge of the card and the chip reading head 601. When the chip on the card contacts the chip reading head 601, chip information recording or reading starts.

[0037] The radio frequency chip information recording unit 7 is located above the contact chip information recording unit 6 and below the transfer plane 17. The radio frequency chip recording antenna board 701 is parallel to the transfer plane 17 and is about 5 - 30 mm apart. When the leading edge of the card passes through the flip sensor SC, the distance between the leading edge of the card and the radio frequency chip recording antenna board 701 is calculated. When the chip antenna on the card approaches the radio frequency chip recording antenna board 701, radio frequency chip information recording or reading starts.

[0038] See Figure 3Schematic diagram of the relationships of the various sensors shown. The flipping sensor SB and the flipping sensor SC are separated by a distance LBC, and LBC is greater than the length L of the card. The card insertion sensor SA and the flipping sensor SB are separated by a distance LAB, and LAB is less than the length L of the card. The above-mentioned card insertion sensor SA, flipping sensor SB, flipping sensor SC, flipping sensor SD, and flipping sensor ESE can adopt a break-type sensor or a microswitch sensor. The flipping sensor SB and the flipping sensor SC are used to detect and ensure that the card remains centered when entering the card flipping part bracket 22, and the card will not touch the above two sensors when the card flipping part bracket 22 flips. The distance between the flipping sensor SD and the axis of rotation 23 of the flipper is greater than the distance between the flipping sensor SB and the axis of rotation 23 of the flipper, so that the card will not touch the flipping sensor SD when the card flipping part turntable 22 flips.

The printing roller swing bracket 41 of the printing unit 10 is located within the area surrounded by the transfer film transfer path 38. One end of the printing roller swing bracket 41 is fixed to the printer bracket 1 through a rotating shaft, which is the swing rotation center of the printing roller swing bracket 41. The rubber printing roller 42 of the printing unit 10 is installed on the swing end of the printing roller swing bracket 41, and the rubber printing roller 42 can freely rotate on the printing roller swing bracket 41 through a bearing. The printing cam 43 of the printing unit 10 is assembled on the printer bracket 1. The rotation direction of the printing cam 43 is controlled by a digital controller through a motor. The rotation position of the printing cam 43 determines the swing direction of the printing roller swing bracket 41, swinging the rubber printing roller 42 on the printing roller swing bracket 41 towards the thermal print head 40 or swinging the rubber printing roller 42 away from the thermal print head 40. When the rubber printing roller 42 swings towards the thermal print head 40, the rubber printing roller 42 presses the transfer film 45 and the ribbon 44 onto the heating wires of the thermal print head 40, printing the ribbon color on the transfer film to form a pattern.

[0042] The present invention discloses a control method for a re-transfer printing card machine. The re-transfer printing card machine adopts the above-mentioned re-transfer printing card machine capable of excluding overlapping card feeding. The control method includes determining whether to discharge the overlapping card into the failed card receiving slot or the completed card receiving slot according to the lengths of the overlapping cards detected by the card feeding sensor SA, the flipping sensor SB, and the flipping sensor SC; when the flipping sensors SB and SC detect overlapping cards, the card flipping unit 4 transports the overlapping cards to the electronic information recording unit and discharges them into the failed card receiving slot through the electronic information recording unit; when the card feeding sensor SA, the flipping sensor SB, and the flipping sensor SC detect overlapping cards, the card flipping unit 4 transports the overlapping cards to the transfer unit and discharges them into the completed card receiving slot through the transfer unit.

[0043] After the leading edge of the card is detected by the card feeding sensor SA and enters the card cleaning unit 3, the card is continuously transported forward by the cooperation of the driving cleaning roller 24 with a known diameter D and the driven cleaning roller 25. When the leading edge of the card is detected by the flipping sensor SB, at this time, the driving cleaning roller 24 is driven by the digital controller through the stepping motor, and the digital controller starts to count until the trailing edge of the card is detected by the card feeding sensor SA, and records the rotation angle N of the driving cleaning roller 24 driven by the stepping motor during this period. COUNT , preset the distance L between the card feeding sensor SA and the flipping sensor SB AB , calculate the calculated length L of the card according to formula 1 COUNT ;

[0044] L COUNT = L AB + πDN COUNT / 360 (Formula 1)

[0045] where L COUNT is the calculated length of the card entering the flipping unit 4, L AB is the distance between the card sensor SA and the flipping sensor SB, D is the diameter of the driving cleaning roller 24, and N COUNT is the rotation angle of the driving cleaning roller 24 during the card entering the flipping unit 4.

[0046] Compare L COUNT with the standard card length L, and preset the distance L between the flipping sensor SB and the flipping sensor SC BC ;

[0047] When L - 1mm < L COUNT < L + 1mm, the card entering the card flipping unit 4 is a normal single card and can continue the subsequent information recording or transfer operation;

[0048] When L + 1mm < L COUNT < L BCWhen it is -1 mm, it means that multiple cards must have been fed in overlapping. However, since the total length under the overlap is less than the distance LBC between the flipping sensor SB and the flipping sensor SC, and its length will not touch the flipping sensor SB, the flipping sensor SC, and the flipping sensor SD during flipping, the above-mentioned overlapping cards are flipped by the card flipping unit 4 to the magnetic stripe information recording plane 29, and are discharged into the failed card receiving slot 14 by the card flipping unit 4 through the magnetic stripe information recording unit 5. At this time, the transfer task can be completed by setting whether to immediately let the card supply unit 2 feed the next card, without manual intervention for troubleshooting.

[0049] When L BC -1 mm < L COUNT When it is, it means that multiple cards must have been fed in overlapping. Since the total length under the overlap is already greater than the distance LBC - 1 mm between the flipping sensor SB and the flipping sensor SC, the length under the overlap may touch the flipping sensor SB, the flipping sensor SC, and the flipping sensor SD during flipping. Therefore, the above-mentioned overlapping cards are directly discharged by the card flipping unit 4 from the transfer plane 17 to the completed card receiving slot 13 through the transfer unit 11 and the card flattening mechanism 12. At this time, the transfer task can be completed by setting whether to immediately let the card supply unit 2 feed the next card, without manual intervention for troubleshooting.

[0050] The above embodiments are only for illustrative purposes and not restrictive. Any equivalent modification or change made without departing from the spirit and scope of this application shall be included in the scope of the claims of this application.
