Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a card reversal transport mechanism. More specifically, the present invention relates to an improvement in the structure of a card reversing transport mechanism used for reversing a card in the course of transport in a card issuing device, for example.
[0002]
[Prior art]
2. Description of the Related Art A card reversing transport mechanism for reversing a card is used, for example, in a printing apparatus for performing printing on a card surface in a card issuing apparatus. The card reversing transport mechanism has, for example, a reversing member that reverses while holding the card, a transport roller and a driven roller that rotates on the reversing member, and rotates the reversing member during card transport to transfer the card together with the reversing member. Turn it over. As such a card reversing and transporting mechanism, there has been devised one that does not have a transporting power source for rotating the transporting roller in the reversing member itself, but transmits the power of the card main transporting section to the transporting roller and rotates it. (For example, see Patent Documents 1 and 2).
[0003]
By the way, in the conventional card reversing transport mechanism, it is possible to feed or remove the card only in the card transport direction, but it is possible to remove the card not only in this direction but also in a direction perpendicular to this, that is, in the direction of the rotation axis. If possible, the card can be fed sideways during the card issuance process, and it is expected that the number of variations in the configuration of the card issuance device will increase, which will lead to a reduction in the size of the device.

[Problems to be solved by the invention]
However, in the conventional card reversing transport mechanism, the card on the reversing member cannot be taken out on both sides in the transport direction. For example, when the reversing member has a structure in which both sides are supported by a support arm, the support arm or the like may be in the way and the card cannot be taken out on both sides in some cases. Further, when the reversing power for reversing the reversing member and the transport power for rotating the transport roller are transmitted from both sides of the reversing member, the transmission mechanism also obstructs the removal of the card from both sides. There were times when I could not do that.
[0006]
Therefore, an object of the present invention is to provide a card reversing and conveying mechanism capable of taking out a card not only in the card conveying direction but also in a direction perpendicular thereto.
[0007]
[Means for Solving the Problems]
In order to achieve this object, an invention according to claim 1 provides a card reversing transport mechanism capable of reversing a card transported on a transport path, a rotatable drive transmission shaft pivotally supported by a base frame, and the drive transmission shaft. A rotating body that is provided coaxially with the shaft and can rotate independently of the drive transmission shaft, and is fixed to this rotating body and is cantilevered, and the unsupported side is open so that the card can be taken out to this open side. Roller, which is driven by the drive transmission shaft and rotates on the reversal member, and which transports the card in a direction perpendicular to the drive transmission shaft while pressing the card with a force capable of being taken out to the open side. And a transport drive source for rotating the transport roller via a drive transmission shaft, and a reversal drive source for rotating the reversal member via a rotator.
[0008]
In this card reversing transport mechanism, a reversing member is cantilevered by a rotating body, and transport power for rotating a transport roller is transmitted by a drive transmission shaft provided coaxially with the rotating body. In other words, in this card reversing and transporting mechanism, a supporting mechanism for rotatably supporting the reversing member and a transmission mechanism for transmitting the conveying power are gathered on one side of the reversing member to open the non-supporting side of the reversing member. It is possible. Therefore, according to the card reversing transport mechanism, the card held on the reversing member can be taken out from the open side.
[0009]
In the card reversing transport mechanism, when the rotational power of the card main transport section is taken out as it is and used as the transport drive source of the transport roller, the transport drive source and the drive transmission shaft It is preferable that a one-way clutch is provided between the first clutch and the second clutch to output either one of the inputs in one direction or the opposite direction and output the rotation in one direction. In this case, the transport roller also rotates reversely with the reverse rotation of the main transport unit, and when the card is reversed with the reversing member, the card transport direction is reversed between the main transport unit and the reversing member, so that the card and the roller collide. However, such a situation can be prevented by always rotating the transport roller in a fixed direction by the one-way clutch.
[0010]

[0012]
Hereinafter, an embodiment in which the card reversing and conveying mechanism according to the present invention is applied to a card issuing device will be described (see FIG. 7 and the like). Although not particularly shown, the card issuing device includes a device for printing on the card surface, for example, a thermal transfer printer using an ink ribbon, or an embosser for providing irregularities on the card 30. Behind the reversing member 7 in the card conveyance direction, a columnar conveyance roller 34 constituting a main conveyance unit for further conveying the card 30 to the back of the card issuing device, and fixed to the ends of these conveyance rollers 34. Provided are pulleys 35, belts 36 wound around these pulleys 35 and transmitting rotational driving force, and the like (see FIG. 1 and the like).
[0013]
A cylindrical sleeve 8 with a flange 8a is fixed to a left plate (hereinafter, simply referred to as "left plate 1") of the base frame 1 (see FIG. 2). A cylindrical member 10 is fitted inside the sleeve 8, and is rotatably supported by the sleeve 8. Inside the cylindrical member 10, for example, a solid drive transmission shaft 9 is provided rotatably with respect to the cylindrical member 10. Further, a cylindrical rotating body 6 is fixed to the outer periphery of the cylindrical member 10 by, for example, press fitting or screwing. The rotating body 6 and the cylindrical member 10 are provided coaxially with the drive transmission shaft 9 and the sleeve 8. The one in which the rotating body 6 and the cylindrical member 10 are integrated, and the drive transmission shaft 9 can be independently rotated with respect to the sleeve 8 (see FIG. 2).
[0014]
The rotating body 6 is a member, for example, a pulley (hereinafter, referred to as a “pulley 6”) that rotates with the tubular member 10 by receiving a driving force of a reversing motor (hereinafter, “reversing motor 2”) that is the reversing drive source 2. A belt 5 that transmits the rotational driving force of the reversing motor 2 is wound around the pulley 6 (see FIG. 2). Further, the pulley 6 cantileverly supports the reversing member 7 via an arm 7a fixed to an end portion of the pulley 6 via a cylindrical member 10, and the pulley 6 is integrated with the rotation of the pulley 6 itself. The reversing member 7 is rotated by the same amount.
[0015]
The reversing member 7 is a member for changing the direction of the card 30 during conveyance, and is rotatable with respect to the left side plate 1 (see FIG. 2). The reversing member 7 of the present embodiment transports the card 30 sandwiched by the transport roller 23 and the driven roller 24 in one direction, and also reverses the sandwiched card 30 by rotating the reversing member 7 itself. As described above, the reversing member 7 is cantilevered by the pulley 6 and rotates integrally with the pulley 6 by the same amount. The non-supporting side (that is, the side opposite to the arm 7a) of the cantilevered reversing member 7 is opened, and the card 30 on the reversing member 7 is opened as shown by a thick arrow in FIGS. It is possible to take it out in different directions. Here, the release means a card on the reversing member 7 such as a guide for restricting the width direction position of the card 30 in contact with the edge of the conveyed card, an arm for supporting the rotating member 7 at both ends, and the like. This refers to a state in which there is no member, component, device, or the like that hinders when the 30 is pulled out to one side, and the card can be drawn in that direction. The reversing member 7 is provided with a card sensor including, for example, photo interrupters 25a and 25b to detect the presence or absence of the card 30 (see FIG. 5 and the like). Reference numeral 7b denotes a guide support, and 7c denotes a card guide.
[0016]
Further, a roller rotation shaft 27 is provided in parallel with a rotation shaft such as the drive transmission shaft 9 (see FIG. 2). The roller rotation shaft 27 is a shaft for rotating the transport roller 23 fixed around the roller rotation shaft 27, and a transmission gear 22 is provided at an end thereof. The transport roller 23 contacts the surface of the card 30 and moves the card 30 in the transport direction. On the other hand, the driven roller 24 is supported by the rotating shaft 29 and is pressed toward the transport roller 23, and rotates in contact with the transport roller 23 or the back surface of the card. The transport roller 23 and the driven roller 24 pinch the card 30 from both sides. The pressing force is a force enough to take out the card 30 to the open side, and the card 30 is allowed to be pulled out even in the pinched state. I do. In this case, if, for example, a roller made of Duracon is used as the driven roller 24, the frictional resistance in the axial direction when the card 30 is taken out can be reduced.
[0017]
The belt 5 is wound around the small-diameter portions of the pulley 6 and the reduction pulley 4 described above (see FIGS. 3 and 6). A belt 3 is wound around a large diameter portion of the speed reduction pulley 4 and the reversing motor 2. The reversing power of the reversing motor 2 is transmitted to the belt 3 → the reduction pulley 4 → the belt 5 → the pulley 6 → the reversing member 7. In this case, it is preferable that a reversible motor be used as the reversing motor 2 because the reversing member 7 can be rotated in any direction. In addition, the rotatable angle of the reversing member 7 may be unlimited, but it is sufficient that the reversing member 7 can rotate at least an angle required for reversing or changing the direction of the card 30. In the present embodiment, the rotation amount of the reversing member 7 is set to a maximum of 270 degrees by, for example, providing a limiter such as a stopper for restricting a rotatable area of the reversing member 7 (see FIGS. 8 to 11). 1 and 2 show a state in which the rotation angle of the reversing member 7 is 0 degree and the surface of the card 30 faces upward, and FIGS. 3 to 6 show a state in which the reversing member 7 is rotated 180 degrees and reversed. This shows a state in which the surface of the card 30 faces downward. Further, the reversing member 7 is provided with a light shielding portion 7d that blocks the sensor 26 when the rotation angle is 270 degrees (see FIGS. 3 and 4).
[0018]
The drive transmission shaft 9 is a member that transmits the rotational drive of the transport drive source 11 to rotate the roller rotation shaft 27 and the transport roller 23. For example, in the present embodiment, the drive transmission shaft 9 passes through the inside of the tubular member 10 and It is rotatably supported by the member 10. On the reversing member 7 side of the drive transmission shaft 9, a transmission gear 21 that meshes with the transmission gear 22 of the roller rotation shaft 27 is provided (see FIG. 2). A pulley 20 is fixed near the shaft end on the opposite side. A belt 19 that transmits the rotational driving force of the transport driving source 11 is wound around the pulley 20. At the end of the drive transmission shaft 9 on the pulley 20 side, a thrust bearing 28 that receives the end surface of the pulley 20 is provided.
[0019]
The belt 19 is provided so as to transmit the rotational driving force of the transport drive source 11 to the drive transmission shaft 9 via the pulley 20. The transport drive source 11 may be taken out from a cylindrical transport roller 34 constituting the main transport section, or may be directly taken out from a transport motor for driving these main transport sections. The power transmission path from the transport drive source 11 to the belt 19 will be described. First, the belt 13 is wound directly or indirectly around the transport motor to transmit the driving force of the transport motor (see FIG. 5). The belt 13 is wound around a pulley 14 and a plurality of other pulleys. A transmission gear 15 is provided coaxially with the pulley 14, and rotates by the same amount as the pulley 14 (see FIG. 4). Further, a transmission gear 16 that meshes with the transmission gear 15 and a one-way clutch 17 that meshes with the transmission gear 16 are provided (see FIGS. 4 and 5). The one-way clutch 17 has, for example, gears 17a and 17b having the same diameter on the same axis. Even if the gears 17a and 17b rotate in any direction due to the operation of a clutch (not shown) provided therein, the output shaft 17c is one. It is provided so as to rotate only in the direction. A pulley 18 is provided on the output shaft 17c of the one-way clutch 17, and a belt 19 is wound between the pulley 18 and the above-described pulley 20 (see FIGS. 3 and 6). In the present embodiment, pulleys 31 and 32 are provided in addition to the pulleys 18 and 20, and the belt 19 is wound around the pulleys 31 and 32 (see FIGS. 3 and 6).
[0020]
As described above, the transport driving force of the transport drive source 11 is: the transport drive source 11 → the belt 13 → the pulley 14 → the transmission gear 15 → the transmission gear 16 → the one-way clutch 17 → the pulley 18 → the belt 19 → the pulley 20 → the drive transmission shaft 9 → The transmission is performed in the order of the transmission gear 21 → the transmission gear 22 → the roller rotating shaft 27 → the transport roller 23. Further, in the present embodiment, the one-way clutch 17 is used so that the mechanism after the one-way clutch 17 rotates only in one direction regardless of the direction in which the mechanism after the transport driving source 11 is rotated. Therefore, the rotation direction of the transport roller 23 is always constant.
[0021]
The operation of the card reversal transport mechanism of the present embodiment will be described.
[0022]
To transport the card 30 on the reversing member 7, the transport drive source 11 is driven to rotate the transport roller 23 so that the card 30 sandwiched between the transport roller 23 and the driven roller 24 is sent in one direction. To To stop the card 30 on the reversing member 7, the transport roller 23 is stopped (see FIG. 1). At this time, since the card 30 is nipped by the transport roller 23 and the driven roller 24, the card 30 does not fall from the reversing member 7 even if the reversing member 7 is reversed in this state. The card 30 can be transported even when the reversing member 7 is rotated at any angle between 0 and 270 degrees (see FIGS. 8 to 11).
[0023]
In addition, in order to turn the reversing member 7 and change the direction while holding the card 30, the reversing motor 2 may be driven. As a result, the reversing member 7 rotates within the range of 0 to 270 degrees while holding the card 30 (see FIGS. 8 to 11). However, at this time, since the transmission gear 22 meshing with the transmission gear 21 revolves around the transmission gear 21, the transmission gear 22 itself rotates by itself, and rotates the transport roller 23 to feed the card 30. In some cases, the position of the held card 30 is shifted, and in some cases, the card 30 is dropped. Therefore, when reversing the reversing member 7, it is desirable to perform the card position control in anticipation of the card shift amount accompanying the reversal amount. For example, when the card shift amount can be grasped, the card 30 is shifted in advance in the card conveying direction to the back side or the near side by the shift amount to cancel the shift at the time of inversion, and the card 30 is placed on the inversion member 7 after the inversion. Can be held at the desired predetermined holding position. Alternatively, the card shift amount at the time of reversing may be eliminated by rotating the drive transmission shaft 9 while reversing the reversing member 7. In the case where only one of the pulley 6 and the drive transmission shaft 9 is driven, in order to prevent the stop side from being affected by the drive side, the stop side motor (the reverse motor 2 or the transport drive source 11 may be used). ) In a non-rotatable brake mode.
[0024]
Further, according to the card reversing and transporting mechanism of the present embodiment, the card 30 held thereon can be shifted to the open side and taken out while the reversing member 7 is stopped.
At this time, the card 30 is pressed against the driven roller 24 by the transport roller 23. When the card 30 is taken out, the card 30 is pressed against the driven roller 24 to take out the card 30 so that the influence of the pressing by the driving roller 23 is reduced. It can be easily taken out.
[0025]
Further, according to the card reversing and conveying mechanism of the present embodiment, the reversing member 7 can be rotated at an arbitrary angle within the range of 0 to 270 degrees to change the direction of the card 30 and feed the card 30. Therefore, for example, various devices such as a printing device, an embossing device, and a card ejection device are radially installed around the reversing member 7 in advance according to the card type, the printing process, and the like, and the cards 30 are radially distributed so as to be defective. The card can be ejected, and each device can perform various processes.
[0026]
The above embodiment is an example of a preferred embodiment of the present invention, but the present invention is not limited to this, and various modifications can be made without departing from the gist of the present invention. For example, in this embodiment, the tubular member 10 is interposed between the sleeve 8 and the drive transmission shaft 9 to indirectly support the drive transmission shaft 9 and to be inverted by using the end surface of the tubular member 10. Although the member 7 is positioned in the thrust direction, the drive transmission shaft 9 may be directly supported by the left side plate 1 or the sleeve 8 without such a cylindrical member 10 interposed therebetween.
[0027]
【The invention's effect】
As is apparent from the above description, according to the card reversing transport mechanism of the first aspect, the reversing member is cantilevered by the rotating body, and the transport power of the transport roller is transmitted by the drive transmission shaft coaxial with the rotating body. Therefore, the non-supporting side of the reversing member can be opened. Therefore, the card held on the reversing member can be taken out from the open side provided on the non-support side in the direction perpendicular to the card transport direction, and the card is laterally fed in the card issuing process in a card issuing device or the like. It becomes possible. For example, when a printer to which the card reversing and conveying mechanism is applied and a magnetic card encoder are arranged in parallel, the card discharged from the printer can be directly slid laterally toward the magnetic card encoder to be fed. Therefore, a smaller space is required compared to a case where the printer is once pulled back to the front side of the printer and then sent to the card encoder side. Therefore, it is advantageous in reducing the size of the device. In addition, it is possible to increase the variations of the configuration of the card issuing device.
[0028]
According to the card reversing transport mechanism of the second aspect, a one-way clutch is provided between the transport drive source and the drive transmission shaft so that the transport roller is always rotated in a fixed direction. It is possible to prevent the occurrence of a situation such as a card collision when inverted.
