Description

Card dispenser

The present invention relates to a card dispenser (Card dispenser or Card Hopper), in particular, even if the amount of loading of the card in the stacking box, the load in the card supply portion is always kept constant and the card feed to ensure that only one card is conveyed Relates to a device.

Generally, a card feeder that can be automatically supplied with a card loaded to print pictures, graphics, texts, etc. on a plastic card such as a credit card, or to input and read information on a magnetic tape or a smart chip of a card. Is needed.

1A and 1B are an overall schematic view of a conventional card supply apparatus. As shown in Fig. 1A, a general card supply apparatus loads a plurality of cards 8 for printing or inputting and reading information on a card support plate 6 supported upward by an elastic force of a spring 5, A rubber roller device 2 is installed on the upper side of the card feeder to drive the uppermost card while driving through the motor 1, and only one card is passed through the lower end of the rubber roller device 2 to be conveyed. The card thickness adjusting device 7 is provided, and is attached to the side wall of the card thickness adjusting device 7 through screws 4 and 4 ', and constitutes a rubber plate 3 for adjusting the thickness of a single card. , The position of the rubber plate 3 to a height through which one card is passed while loosening or tightening the screws 4 and 4 'with a plurality of cards 8 loaded on the upper surface of the support plate 6 of the card feeder. , Adjust the screws (4, 4 ') again, then reassemble the motor (1). To transfer the card.

However, the above-mentioned conventional card feeder is generally susceptible to card scratches when the first card is transferred, so that the rubber plate 3 is placed on the underside of the card to prevent scratches and to allow only one card to pass. In order to install, for the friction with the rubber roller device (2) in contact with the upper surface of the card is required a spring (5) for supporting the card with a strong force.

Therefore, due to the tension force limit of the spring (5), only a small amount of card loading should be set, and the last few cards due to the lack of restoring force of the spring (5), which occurs when a large number of cards are loaded for a long period of time, the card feed cannot be supplied for the last few cards. It didn't happen. In addition, after adjusting the rubber plate 3 up and down little by little in setting the thickness of the card, and experimenting with dozens of card sheet feeding conditions, if it does not work normally, the rubber plate is adjusted up and down again to check dozens of card sheet feeding conditions. The rubber plate 3 was fixed after continuing the repetition function.

On the other hand, as shown in Figure 1b, in order to solve the above problems, the card 114 'from the top to enable a small amount of the last card transfer to the rubber roller device 112 and the card storage 119 driven by the motor (11). To prevent the left and right movement of the card opening 113 and the metal plate 114, which outputs the metal plate 114 and the card 114 ', which can be manually inserted / extracted, to press the), and supports the back of the card. It has been proposed a card supply device consisting of a circular rod 110. However, the card supply device described above is limited to 0.2 in accordance with normal use by limiting the card opening 113 to the current credit card thickness (0.76 mm). Cards between mm and 2mm should be configured as a separate set for each card type, since cards that are more than two thin cards and 0.76mm or larger cards cannot be transported at all in one operation. (110) Due to the inability to insert the card at the back of the card loading box 119, the card angle is tilted back and forth at the side of the card loading box 119, and it is inconvenient to load the card several times in small quantities or several times on the card loading box 119. And because the card thickness adjustment is fixed, there was a problem that only cards of a specified thickness are supplied in sheets.

Accordingly, the present invention has been made in order to solve the above problems, the card is supplied so that the load is distributed in the middle part even if a large amount of cards are loaded so that a large amount of cards can be easily loaded at a time. The purpose is to provide a device.

Yet another object of the present invention is to enable accurate and easy adjustment of card openings according to card thickness. In addition, the present invention is to supply only one card so that the next card does not receive a transfer force until it is completely discharged by supplying one card.

In addition, the card supply apparatus of the present invention, by opening the back of the card loading box to load the card and then closing the rear cap of the loading box to prevent the card from being pushed back or moving, and easy to insert the card and keep the loading state accurately It is to make it possible.

And the card supply apparatus of this invention can provide not only the card supply apparatus for card printers, but also as a card vending machine or various card supply apparatuses for storing and supplying each card one by one.

And to guide the transfer of the card. Here, in the drawings of the reduction gear 22 and the transfer roller 23 is illustrated as being connected to the belt, but is not limited to this can be configured to be transmitted through a power transmission means such as a gear bite.

The card thickness setting means is provided on the outside of the front of the stacking box 10, the control plate 31 to block the opening of the front of the stacking box 10 to pass only one card, and in the center of the control plate 31 A fixing rod 32 is fixed to the lower end and penetrates the upper protrusion of the front plate of the loading box 10, and a spring is installed on the upper end of the fixing rod 32 to elastically support the fixing rod 32 downward. 33) and the fixing rod 32 is fixed to the middle of the front plate of the loading box 10 and the fixing rod 32 is coupled to be freely moved up and down to set the position of the adjusting plate 31, the fixing rod 32 It is composed of a fixing means for fixing the fixing bolt 34. Here, in the present invention as a means for fixing the fixing rod 32 is fixed to the cylindrical member on the front plate and the cylindrical portion of the cylindrical member of the front plate Load by configuring to protrude inward It is configured to form a convex portion 51 of the means, and forms a vertical through-hole on the outside of the front plate so that the fixing rod 32 is inserted through, and the bolt is coupled to the cylindrical member to fix the fixing rod 32 Configure it to work.

The opening and closing means of the loading box is installed through the rotation shaft 44 at the lower end of the loading box 10, that is, the rear side of the side plate, and closes the loading box 10 to prevent the card from being separated, and the rotation shaft 44 is centered. When the loading box rear cap 41 is rotated, a leaf spring 43 is provided to provide elastic force at the time of opening and closing, and the elastic force of the leaf spring 43 provides the elastic force in the direction of travel when opened and closed. The support piece 42 for this is formed and comprised.

The load distributing means has a convex portion 51 and a concave portion 52 corresponding to the loading box 10 and the rear cap 41 on an upper portion of a predetermined height from the bottom surface 11 of the loading box 10. ) Is formed to distribute the load of the stacked card so as not to affect the lower portion, and the weight 60 is provided on the upper portion of the stacked card to provide the load to the lower portion of the card at a predetermined weight.

On the other hand, although not shown in the drawings, in order to maintain a more stable state when the rear cap 41 is closed to form a coupling hole on both sides of the middle portion of the rear cap 41, The elastic pieces formed on both sides of the middle portion are installed, respectively, and end portions of the elastic pieces may be formed to have a locking protrusion coupled to the coupling hole of the rear cap 41 to flexibly fix the closed state of the rear cap.

The operation of the card supply apparatus for a card printer according to the present invention configured as described above will be described.

First, it is important to load a large number of cards and to supply one by one by loading the cards in the stacking box and supplying them one by one according to card printing. So that the structure of the stacking box 10 is composed of a side plate and a bottom plate with the front plate and the rear portion open so that a large number of cards from the rear can be loaded at once. Then, the rear cap 41 is configured to be closed after the card is loaded in a locked form to prevent the card from being separated from the side and rear of the loading box.

Further, the leaf spring 43 is installed in the lower portion of the rear cap 41, that is, in the closing path of the rear cap, and both the directions of the rear cap 41 are opened and closed by the elastic force of the leaf spring 43. The positions of the two support pieces 42 and the rotational shaft 44 were designed and configured to receive the elastic force. That is, the corner portion of the support piece 42 is rounded, and the position of the pivot shaft 44 is located inside the corner of the support piece 42 so that the opening of the leaf spring 43 is closed. Since the elastic force is received at each corner of the support piece 42, the elastic force can be received in both the opening and closing directions in the advancing direction.

On the other hand, the load distributing means forms a convex portion 51 and a concave portion 52 corresponding to each other in the stacking box 10 and the rear cap 41 so that the load of the loaded card is lowered by the convex / concave portion. It is not delivered. The guide piece 45 is formed to protrude on the inner surface of the rear cap 41 at regular intervals, and a concave portion 52 concave rounded is formed on the guide piece 45. A convex portion 51 having a convex shape corresponding to the concave shape of the concave portion 52 is formed in the middle of the plate. In the embodiment of the present invention, the cylindrical member is fixed to the outside of the front plate and a portion of the cylindrical member protrudes to the inside of the front plate to form a convex portion 51, and the fixing rod 32 is formed on the outside of the front plate. In addition to being penetrated, the fixing rod 32 is configured to be fixed by a fixing bolt 34. Therefore, when the card is loaded in the stacking box 10, the load of the card loaded on the upper part by the relationship between the convex part 51 and the concave part 52 is caught in contact with the convex part 51 and the concave part 52. Therefore, almost no load is transmitted to the lower part of the convex / concave part. Therefore, the load of the card loaded on the bottom surface 11 is loaded by the number of cards loaded up to the convex / concave part, and on the contrary, the transfer roller The reaction acting upward by the friction with 23 is blocked by the convex / concave portion, so that the feed roller 23 and the card at the bottom end act as a constant load to transfer the card.

At this time, since the vertical movement direction of the card is moved in a zigzag form by the convex part 51 and the concave part 52 when the loaded card is lowered according to the supply of the card, both ends of the card are caught by the convex / concave part. In addition, the effects of falling one by one can prevent the card supply malfunction due to the close contact between the cards. In addition, if more convex / concave portions are provided with electrostatic absorbing contact means for dissipating static electricity, the static electricity can be more effectively dissipated.

Therefore, by distributing the load of the card loaded in the stacking box 10, the frictional force between the lower transfer device and the card is always constant, thereby preventing supply errors due to damage to the surface of the card or close contact between the card and the card. It can be increased, so that management for card supply becomes very convenient, for example, in a high speed large capacity card printer or a vending machine.

On the other hand, the card thickness setting means of the present invention is to block the opening of the front plate of the stacking box 10 by elevating the control plate 31 to adjust so that only one card can pass. At this time, the fixing rod 32 is fixed upward in the center of the adjustment plate 31, the fixing rod 32 is fitted into the protrusion projecting to the upper end of the front plate through the cylindrical member, the elastic force downward to the protrusion This working spring 33 is fixed to the fixed rod (32).

Accordingly, the spring is compressed by holding the upper end of the fixing rod 32 in a state in which the fixing bolt 34 is fixed to the cylindrical member to loosen the fixing bolt 34 so that the fixing rod 32 can be freely moved up and down. Lifting up, inserting one card into the lower part of the adjusting plate 31 and placing the fixing rod 32, the height of the adjusting plate 31 is naturally set by the force of the spring 33. In this state, the card can be freely transferred. Tighten the fixing bolts 34 again while finely adjusting the height of the adjusting plate 31 using the fixing bolts 34 so that the card thickness can be accurately set to match the thickness of one card. Only chapters are discharged.

At this time, the conveying apparatus, the surface of the conveying roller 23 in the center using a roller formed with a surface of the rubber material that can increase the friction force with the card, the first and second guide rollers (24, 25) ) Is configured to guide the card transfer while the card is naturally rotated. That is, the power of the transfer motor 21 is transmitted only to the feed roller 23, and the first and second guide rollers 24 and 25 are powered. It is rotated to be transported without scratching the card to be transported without it plays a role to help the transfer.

In addition, by setting the height of the conveying roller 23 and the height of the front second guide roller 25 to be the same, and lowering the height of the rear first guide roller 24, a single card is conveyed and the conveying roller ( In a state in which the frictional force of 23 is no longer transmitted, the next card does not come into contact with the transfer roller 23 due to the card which is not completely released. Accordingly, the next card is not supplied until the card discharged from the card feeder is taken from the print head installed at the front end.

Effects of the card supply apparatus according to the present invention as described in detail above are as follows.

First, by having a rear cap that opens and closes to open and close the rear side of the stacker, a large amount of cards can be loaded at a time, and the rear cap can receive elastic force in both open / closed and semi-locked state when closed. It is effective to maintain.

Second, the load can be increased in a large amount by spreading the load by forming a convex / concave in the middle of the loading box and the rear cap, and the frictional force between the transfer device and the card is always constant, resulting in damage to the surface of the card or close contact between the card and the card. Supply errors due to static electricity can be prevented.

Third, by supplying power only to the feed rollers and by providing a height difference from the guide rollers, after one card is supplied and the supplied card is completely ejected, the next card is transferred and only one card is supplied. .

Fourth, it is possible to set the opening size of the card supply part easily and accurately according to the thickness of one card by installing the fixing rod on the adjusting plate and providing proper downward contact force by spring to prevent the error of misalignment or misalignment when the card is inserted. There is an advantage.
