[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to punching of a laminated body for card production required in the production process of various cards such as a magnetic card, an IC card, and the like used as a cash card, a credit card, a member's card, and a leaving / managing card. In particular, the present invention relates to a technique for improving work efficiency and punching dimensional accuracy in a punching step of a laminated body for card production.

2. Description of the Related Art A magnetic card MD having a two-layer type core is:
As shown in the perspective view of FIG. 21 and the exploded perspective view of FIG. 22, the printed two-layer plastic plate PL
A transparent plastic film overlay PL4, PL5 is attached to the front and back of a core (substrate) PL3 composed of PL1, PL2, and an overlay PL serving as a surface thereof.
4 has a small-width magnetic tape PL6 attached to the outer surface thereof. In this specification, the magnetic tape P
The description will be made assuming that the attachment side of L6 is basically the front side of the magnetic card MD.

[0003] Conventionally, the magnetic card as described above is manufactured as follows. (1) After a large number of card units are stacked vertically and horizontally on a rectangular large-sheet-like sheet-like front-side core material and back-side core raw material, a magnetic tape is further adhered to the front side. A temporary fixing laminate is prepared by laminating an overlay with a tape and an overlay having no magnetic tape adhered to the back surface side. (2) Next, when the temporarily-fixed laminate is thermocompressed between layers by a hot press, a laminate for manufacturing a magnetic card in the form of a rectangular large-sized sheet in which a number of magnetic card units are arranged vertically and horizontally is obtained. (3) Subsequently, the rectangular magnetic card manufacturing laminate is punched by a punching machine, and the magnetic card units are punched line by line while being pitch-fed in the longitudinal (longitudinal) direction at the pitch of the magnetic card units. , Get a magnetic card.

[0004]

However, in the conventional magnetic card manufacturing method, there is a problem that the working efficiency in the punching step of the laminated body for manufacturing a magnetic card is not good, and the punching dimensional accuracy is not sufficient. Since a dimensional change due to heat shrinkage occurs before and after thermocompression bonding by a heating press in the laminated body for manufacturing a magnetic card, in the punching step, first, the arrangement interval of the magnetic card units in the vertical direction which is the pitch feed direction of the laminated body is set. Measure by sampling. As a result, it takes a lot of time and labor to measure the vertical arrangement interval of each magnetic card. As a result, the work efficiency is not good in the whole punching process.

On the other hand, when the laminated body for manufacturing a magnetic card is different or the location is different even in the same laminated body, the arrangement interval does not always coincide with the arrangement interval obtained by sampling measurement. The heat shrinkage differs depending on the difference in the laminate and the location on the laminate, and the actual arrangement interval varies considerably, and may be different from the arrangement interval obtained by measurement. On the other hand, when the laminated body for magnetic card production is punched in units of magnetic cards, the laminate is pitch-fed to the die of the punching machine at the arrangement interval determined by the measurement. Therefore, when punching a portion at an array interval different from the array interval determined by the measurement, the pitch is different, so that the position of the magnetic card unit does not match the position of the mold, resulting in poor punching dimensional accuracy and improper punching. You will see the generation of non-defective products.

Before the magnetic card manufacturing laminate is pitch-fed to a die of a punching machine, the magnetic card manufacturing laminate is positioned on a positioning stage in a direction orthogonal to the pitch feeding direction. That is, if the magnetic card manufacturing laminate is not positioned in the direction perpendicular to the pitch feed direction, a misalignment occurs between the punching die and the card unit in the laminate even if the pitch is correctly fed. It is because it is not punched correctly. Conventionally, this type of positioning is performed by the operator by aligning the positioning mark optically projected on the positioning stage with the positioning index on the magnetic card manufacturing laminate, so that the work efficiency is improved. And the positioning accuracy itself was poor.

The present invention has been made in view of the above circumstances, and provides a punching apparatus for card production which can improve the working efficiency in the step of punching a laminate for card production and can always punch out a card with high dimensional accuracy. As an issue.

[0010]

The operation of punching a card manufacturing laminate by the card manufacturing punching device according to claim 1 (hereinafter referred to as "punching device" as appropriate) will be described. First, when the laminate carrying means is carried into a positioning stage for performing positioning in a direction perpendicular to the direction of pitch feed at the time of punching, a sheet-like card-forming laminate including card units arranged and arranged, Positioning means provided on this stage performs positioning in a direction perpendicular to the pitch feed direction based on a positioning index provided on the card manufacturing laminate. After the positioning is completed, the laminated body for card production is transported by the laminated body transporting means to the punching stage having the laminated body punching means. In the punching stage, the feed index detecting means detects pitch feed indexes attached to the card manufacturing laminate at intervals corresponding to the arrangement intervals of the card units along the alignment direction of the card units, while the feed index detecting means In accordance with the detection result obtained in step (a), the transport control means feeds the card manufacturing laminate to the laminate punching means at a pitch, and the punch control means punches the card manufacturing laminate in conjunction with the pitch feeding of the card manufacturing laminate. By performing the operation, the punching operation for each card unit proceeds promptly.

Next, the operation of the above-described punching device in the positioning stage will be described. At least the stack moving means on the fixed reference position side, which is also the center of rotation of the semi-fixed gripping means, independently grips the card manufacturing laminate with the claws to perform horizontal movement, and the optical index detecting means for the positioning index. Stops horizontal movement when is detected. Then, while the gripping claws of the stack moving means are opened, the stack for card production is held by the semi-fixed holding means. After that, another stack moving means alone moves horizontally by gripping the card manufacturing stack with the claws and the optical index detecting means corresponding to the stack moving means detects the positioning index. Stop horizontal movement. This completes the positioning.
In the case of this positioning, while the card manufacturing laminate is being pulled by another stack moving means later, the portion of the card manufacturing laminate that has reached the fixed reference position first (that is, the positioning index is drawn). Since a certain part) is gripped by the semi-fixed gripping means, the positioning index previously reached the fixed reference position does not deviate from the fixed reference position, and the other positioning index reaches the fixed reference position. Then, both positioning indices are both at their respective fixed reference positions, and precise positioning is achieved.

On the other hand, as shown in FIG. 10, the upper ends 16a and 17a of the support arms 16 and 17 are connected by a connection bar 25. Both ends 25a and 25b of the connection bar 25 are supported by the screw members 26, respectively.
The screw members 26 are rotatively attached to the upper end portions 16a and 17a of the sixth and the 17th. Therefore, the movement of the other supporting arm is stopped by the connecting bar 2.
5, the groove 24 moves and the support arm 16 slides slightly in the pitch feed direction.
The rotational displacement of the magnetic card manufacturing laminate 1 due to the movement of the other support arm alone is performed without difficulty.

As shown in FIG. 11, each of the gripping claws 14 and 15 comprises an upper claw piece 31 and a lower claw piece 32.
The upper claw piece 31 and the lower claw piece 32 are moved in the approaching direction or the separating direction by the driving of, and the gripping operation and the releasing operation are performed. The gripping surface of the upper claw piece 31 is constituted by the spherical surface of the ball 33, and the gripping surface of the lower claw piece 32 is constituted by a flat upper surface of a cylinder 34 provided rotatably in the circumferential direction by a bearing 35. . That is, the gripping claws 14, 15

(2) When the gripping claws 14 and 15 are pulled down in a direction perpendicular to the pitch feed direction while holding the magnetic card manufacturing laminate 1, as shown in FIG. The optical index detector 38 on the side of the fixed reference position 36 detects the positioning index Mb and stops the movement of the gripping claws 14.

(3) On the other hand, the gripping claws 15 are pulled down in the direction perpendicular to the pitch feed direction while holding the magnetic card manufacturing laminate 1, and fixed as shown in FIG. 13 (c). The optical index detector 39 on the reference position 37 side eventually detects the positioning index Mb and stops the movement of the gripper 15. Thus, the rough positioning is completed. At this time,
At the fixed reference position 37, the positioning index Mb is exactly aligned, but at the fixed reference position 36, when only the gripper 15 is pulled down, the magnetic card manufacturing laminate 1 rotates around the stopped gripper 14. As a result, the positioning index Mb on the side of the gripper 14 slightly deviates from the fixed reference position 36.

(4) Next, both gripping claws 14 and 15 are
As shown in FIG. 4 (a), the magnetic card manufacturing laminate 1 is simultaneously pushed back by the same distance until both positioning indices Mb are slightly above the fixed reference positions 36 and 37.

(6) Subsequently, the gripping claw 15 on the fixed reference position 37 side grips the magnetic card manufacturing laminate 1 and pulls down in a direction perpendicular to the pitch feed direction to detect the optical index on the fixed reference position 37 side. When the device 39 detects the positioning index Mb and stops the movement of the gripper 15, as shown in FIG. 14C, the positioning index Mb is set at both the fixed reference positions 36 and 37.
Are aligned, and the magnetic card manufacturing laminate 1 is precisely positioned. In the above case, the grip portion 41 was not used at all, but depending on the situation of misalignment of the magnetic card manufacturing laminate 1, only the grip portion 41 was used, and conversely, the grip portion 40 was not used at all. Absent.

Next, a description will be given of the structure of the laminate conveying means for sending the magnetic card production laminate 1 whose positioning has been completed to the punching stage. In the embodiment, two sets of transfer means are provided. Each of the stacked body conveying means includes two conveying claws 53 for gripping the short side edge of the laminated body 1 for magnetic card production. As shown in FIGS. The body 1 is configured to be conveyed by grasping and pressing the short side edge of the body 1. The transport claw 53 is attached to one side 54a of the L-shaped support arm 54 in parallel with a slight space therebetween, while the other side 54b is attached to a moving piece 55 that moves in the transport direction via a rodless cylinder 56. ing. A screw shaft 58 and a moving piece 55 which are rotationally driven by the rotation of the motor 59 shown in FIG. 1 and are installed with their longitudinal direction oriented in the transport direction (pitch feed direction) are screwed together. The moving piece 55 reciprocates by the rotation of 58. Therefore, as the moving piece 55 reciprocates due to the rotation of the motor 59, the transport claws 53 move, and the magnetic card manufacturing laminate 1 is transported.

As shown in FIG. 16, the transfer claw 53 includes an upper claw piece 61 and a lower claw piece 62 that perform gripping / releasing operations by driving the cylinder 60. When the transfer operation is performed, the cylinder 60 is driven. The upper claw piece 61 and the lower claw piece 62 are brought closer to each other to grasp the edge of the shorter side of the back of the magnetic card manufacturing laminate 1, and then, as the motor 59 rotates, the transport claw 53 is moved to the magnetic card manufacturing laminate. 1 will be pushed and conveyed. Then, in the apparatus of the embodiment, as shown in FIG. 15, when one of the stacked body transfer means is performing the transfer operation, the other stacked body transfer means is waiting on the lower side, and the upper stacked body transfer means. When the means completes the transport operation of one magnetic card manufacturing laminate 1, the support arm 54 of the laminate transport means that has completed the transport operation is lowered by driving the cylinder 56, as indicated by the dashed line in FIG. On the other hand, the support arm 54 of the other stacked body transporting unit, which has been waiting, rises in the opposite direction, and enters the state of transporting the next stacked body 1 for magnetic card production. Thus, the waiting time can be reduced by alternately performing the transport operation by the two stacked body transport units.

Next, the configuration of the punching machine (punching means) 65 installed on the punching stage F3 will be described.
As shown in FIGS. 3 and 17, the punching machine 65 includes a die 66 having a punching shape of the magnetic card unit CU of the magnetic card manufacturing laminate 1. The mold 66 includes a fixed mold 67 located below the magnetic card manufacturing laminate 1 that is conveyed, and a movable mold 68 located above the laminate 1. The movable mold 68 is a support block 69 that moves up and down.
It is attached in the form that it is hung underneath. On the other hand, as shown in FIGS. 2 and 3, a motor (not shown)
Is transmitted to the crank 72 via the clutch 71 and converted into a reciprocating motion. And this crank 7
Each time the support block 69 moves up and down by the two reciprocating motions, the movable die 68 moves in and out of the fixed die 67, so that the punching operation by the die 66 is performed. The punched and completed magnetic card MD is placed on a conveyor 73 below the mold 66 and is carried from the shooter 74 to a carry-out conveyor CB2.

On the other hand, as shown in FIGS. 17 and 18,
A little before the die 65 of the punching machine 65, an optical (pitch feed) index detector (feed index detecting means) 7 for detecting the pitch feed index Ma of the magnetic card manufacturing laminate 1 7
5 is attached to the support piece 76 and installed.
The optical index detector 75 is provided at a pitch feed direction arrangement interval for one magnetic card unit in a direction opposite to the transport direction, that is, at a position in front of the pitch by one pitch in the feed direction. This optical index detector 75 is a pitch feed index M
Each time a is detected, a detection signal is sent to the transport control means (not shown) and the punching control means (not shown). The transport control means having received the detection signal controls the laminate transport means so as to temporarily stop the transport of the magnetic card manufacturing laminate 1 to execute pitch feed, and simultaneously performs the punching control which has received the detection signal. The means controls the punching machine 65 to perform the punching operation once while the conveyance is stopped, and executes the punching process on the magnetic card manufacturing laminate 1 one after another. These transport control means and punching control means are mainly constituted by electronic circuits.

When the punching process by the punching machine 65 is completed, as shown in FIG. 19, the unnecessary stacked body 81 is dropped into the waste basket 82 without the feed roller 80 at the tip of the punching machine 65. The feed roller 80 includes a lower roll 83 and an upper roll 84. The upper roll 84 moves up and down by driving a cylinder 85, so that the upper roll 84 is separated from and brought into contact with the lower roll 83. During the punching process, as shown in FIG. 19, the upper roll 84 is at the raised position, and the magnetic card manufacturing laminate 1 is fed in a pitch without sandwiching the gap between the two rolls 83, 84. When the punching process is completed, the upper roll 84 descends and the two rolls 83, 84 pinch and rotate the punched laminated body 81, whereby the punched laminated body 81 is sent to the front scrap basket 82. . Wheels are attached to the bottom side of the scrap basket 82. When the scrap basket 82 becomes full with the punched laminated body 81, the empty scrap basket is replaced.

[Step S13] Following the stop of the magnetic card manufacturing laminate 1, a punching operation is performed to complete the magnetic card MD. Thereafter, each time the pitch feed index Ma is detected, the magnetic card manufacturing laminate 1 is stopped and punched.

[Step S14] When the number of punching operations reaches a predetermined number, the punching processing of the magnetic card manufacturing laminate 1 in units of magnetic cards being transported is completed, and the transport claws 53 are released and The punched laminated body 81 is fed into a scrap basket 82 by a feed roller 80.

The punching device of the present invention can be modified as follows.

(1) The device of the present invention is not limited to the production of magnetic cards, but also includes the production of cards without magnetic tape and IC cards.

(2) In the apparatus of the embodiment, a semi-fixed type gripping portion for gripping the magnetic card manufacturing laminate so as to allow only rotation is provided at both fixed reference positions. The semi-fixed grip may be provided only at the reference position. However, in this case, at the time of a precise positioning operation, the gripping claw near the semi-fixed gripping portion grips the magnetic card manufacturing laminate first and pulls down.

(3) In the apparatus of the embodiment, when positioning the laminated body for manufacturing a magnetic card in the direction perpendicular to the pitch feed direction, rough positioning is performed first, and then fine positioning is performed. Fine positioning may be performed without going through a rough positioning process.
That is, when the magnetic card manufacturing laminate 1 is carried into the positioning stage F2, the edge of the long side thereof is grasped and the claws 14, 1 are gripped.
Grab with 5. Next, one gripping claw (in the case where only one semi-fixed gripping portion is provided, the gripping claw on the side where the semi-fixed gripping portion is provided) is horizontally moved, and the optical portion on the gripping claw side is moved. It stops when the expression index detector detects the positioning index Mb. Then, the gripping claws are released, and the magnetic card manufacturing laminate 1 is gripped by the gripping portion.
Thereafter, the other gripping claw is moved horizontally, and stopped when the optical index detector on the gripping claw side detects the positioning index Mb. This completes the positioning. According to such a positioning method, the processing efficiency of the positioning is improved by the amount that the rough positioning is not performed.

[0056]

According to the punching apparatus for manufacturing a card according to the first aspect of the present invention, the pitch index Ma is automatically detected by the optical index detecting means of the punching stage, so that each card unit can be used. Since the punching is performed while detecting the arrangement intervals mechanically one by one without manual operation, the working efficiency in the punching process can be improved, and the card can always be punched with high dimensional accuracy.

According to the punching apparatus for manufacturing a card according to the first aspect of the present invention, in addition, the positioning in the direction orthogonal to the direction of the pitch feed of the laminated body for manufacturing a card is precisely performed. The card can be punched with high dimensional accuracy.
