[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a card reverse conveyance mechanism. More specifically, the present invention relates to an improvement in the structure of a card reversing / conveying mechanism used for reversing a card in the middle of conveying, for example, in a card issuing device.
[0002]
[Prior art]
A card reversing conveyance mechanism for reversing a card is used in, for example, a printing apparatus that performs printing on a card surface in a card issuing apparatus. The card reverse conveyance mechanism has, for example, a reversal member that reverses while holding the card, a conveyance roller that rotates on the reversal member, a driven roller, and the like. Invert. As such a card reverse conveyance mechanism, a device that does not have a conveyance power source for rotating the conveyance roller in the reversing member itself but transmits the power of the card main conveyance unit to the conveyance roller for rotation is devised. (For example, see Patent Documents 1 and 2).
[0003]
By the way, in the conventional card reversing and transporting mechanism, it is possible to send or take out the card only in the card transporting direction. If possible, it is possible to cross-feed cards in the card issuing process, increasing the number of variations in the configuration of the card issuing device, which is expected to lead to miniaturization of the device.

[Problems to be solved by the invention]
However, in the conventional card reverse transfer mechanism, the card on the reverse member cannot be taken out on both sides in the transfer direction. For example, in the case where the reversing member has a structure in which both ends 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. Further, when the reversing power for reversing the reversing member and the transporting power for rotating the transport roller are transmitted from both sides of the reversing member, the transmission mechanism is also obstructed to take out the card from both sides. There was a case that could not be done.
[0006]
Accordingly, an object of the present invention is to provide a card reversing / 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, the invention according to claim 1 is a card reversing / conveying mechanism capable of reversing a card conveyed on a conveying path, a rotatable drive transmission shaft supported by a base frame, and this drive transmission. A rotating body that is coaxial with the shaft and can rotate independently of the drive transmission shaft, is fixed to the rotating body and is cantilevered, and the unsupported side is opened so that the card can be taken out to the opened side. A reversing member that is held in a stable state and a roller that is driven by a drive transmission shaft and rotates on the reversing member, and conveys the card in a direction perpendicular to the drive transmission shaft while pressing the card with a force capable of taking out the card to the open side. And a conveyance drive source that rotates the conveyance roller via the drive transmission shaft, and a reversal drive source that rotates the reversal member via the rotating body.
[0008]
In this card reverse conveying mechanism, the reversing member is cantilevered by the rotating body, and the conveying power for rotating the conveying roller is transmitted by a drive transmission shaft provided coaxially with the rotating body. That is, in this card reverse conveyance mechanism, the support mechanism for rotatably supporting the reverse member and the transmission mechanism for transmitting the conveyance power are collected on one side of the reverse member, and the non-support side of the reverse member is opened. It is possible. Therefore, according to this card reversing and conveying mechanism, it is possible to take out the card held on the reversing member from the open side.
[0009]
Further, in this card reverse transport mechanism, when the rotational power of the card main transport unit 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 as claimed in claim 2. Is preferably provided with a one-way clutch that outputs a rotation in one direction in either one direction or the opposite direction. In this case, the conveying roller also rotates in reverse with the reverse rotation of the main conveying unit, and when the card is reversed together with the reversing member, the card conveying direction is reversed between the main conveying unit and the reversing member, and the card and roller collide. However, such a situation can be prevented by always rotating the conveying roller in a fixed direction by the one-way clutch.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the configuration of the present invention will be described in detail based on an example of an embodiment shown in the drawings.
[0011]

The card reversing / conveying mechanism according to the present invention includes a rotatable drive transmission shaft 9 that is pivotally supported by the base frame 1, and is provided coaxially with the drive transmission shaft 9 and can rotate independently of the drive transmission shaft 9. A rotating body 6, a reversing member 7 fixed to the rotating body 6 and supported in a cantilever manner and having an unsupported side opened and holding the card 30 in a state where it can be taken out to the opened side, and a drive transmission shaft 9. A roller that is driven and rotates on the reversing member 7 and that conveys the card 30 in a direction perpendicular to the drive transmission shaft 9 while pressing the card 30 with a force capable of being taken out to the open side, and the drive transmission shaft 9 A conveyance drive source 11 that rotates the conveyance roller 23 and a reversal drive source 2 that rotates the reversal member 7 via the rotating body 6 are provided.
[0012]
In the following, an embodiment in which the card reverse 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 illustrated, 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. At the back side of the reversing member 7 in the card transport direction, a cylindrical transport roller 34 constituting a main transport unit for transporting the card 30 further to the back side of the card issuing device, and fixed to the end portions of the transport rollers 34 And a belt 36 that is wound around the pulley 35 and transmits a rotational driving force (see FIG. 1 and the like).
[0013]
A cylindrical sleeve 8 with a flange 8a is fixed to the left side plate (hereinafter simply referred to as “left side plate 1”) of the base frame 1 (see FIG. 2). A tubular member 10 is fitted inside the sleeve 8 and is rotatably supported by the sleeve 8. For example, a solid drive transmission shaft 9 is provided inside the cylindrical member 10 so as to be rotatable 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 press-fitting or screwing, for example. The rotating body 6 and the cylindrical member 10 are provided coaxially with the drive transmission shaft 9 and the sleeve 8. The rotating body 6 and the cylindrical member 10 integrated with each other and the drive transmission shaft 9 can rotate independently with respect to the sleeve 8 (see FIG. 2).
[0014]
The rotating body 6 is a member such as a pulley (hereinafter referred to as “pulley 6”) that rotates with the cylindrical member 10 under the driving force of a reversing motor (hereinafter referred to as “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 cantilever-supports the reversing member 7 via an arm 7a fixed to the end portion thereof via the cylindrical member 10, and this pulley 6 itself is integrated as the pulley 6 rotates. 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 in the middle of 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 between the transport roller 23 and the driven roller 24 in one direction, and reverses the sandwiched card 30 as the reversing member 7 itself rotates. As described above, the reversing member 7 is cantilevered by the pulley 6 and rotates integrally with the pulley 6 by the same amount. Further, the non-supporting side (that is, the side opposite to the arm 7a) of the reversing member 7 that is cantilevered is opened, and the card 30 on the reversing member 7 is opened as shown by the thick arrows in FIGS. It is possible to take out in the direction. The term “open” as used herein refers to, for example, a card on the reversing member 7 such as a guide that contacts the edge of the card to be conveyed and restricts the position in the width direction of the card 30 or an arm that supports the rotating member 7 at both ends. This means that there is no member, part, device, or the like that will obstruct the case when the card 30 is pulled out to one side, and the card can be pulled out in that direction. The reversing member 7 is provided with a card sensor composed of, for example, photo interrupters 25a and 25b in order to detect the presence / absence of the card 30 (see FIG. 5 and the like). Reference numeral 7b denotes a guide support portion, and 7c denotes a card guide.
[0016]
Further, the roller rotation shaft 27 is provided in parallel with the 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 the end thereof. The conveyance roller 23 contacts the surface of the card 30 and moves the card 30 in the conveyance 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 is driven to rotate while contacting the transport roller 23 or the back surface of the card. The transport roller 23 and the follower roller 24 hold the card 30 from both sides, but the pressing force is such a force that the card 30 can be taken out to the open side, and the card 30 is allowed to be pulled out even when held. To do. In this case, if, for example, a Duracon roller 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 the large diameter portion of the speed reduction pulley 4 and the reversing motor 2. The reversing power of the reversing motor 2 is transmitted in the order of belt 3 → deceleration pulley 4 → belt 5 → pulley 6 → reversing member 7. In this case, it is preferable to employ a motor capable of forward and reverse rotation as the reversing motor 2 because the reversing member 7 can be rotated in any direction. In addition, although the rotation possible angle of the reversing member 7 may be unlimited, it is sufficient if at least an angle necessary for reversing or changing the direction of the card 30 can be rotated. In the present embodiment, the rotation amount of the reversing member 7 is set to a maximum of 270 degrees, for example, by providing a limiting means such as a stopper that restricts the rotatable region 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 degrees 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. The state where the surface of the card 30 faces downward is shown. 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 conveyance drive source 11 and rotates the roller rotation shaft 27 and the conveyance roller 23. For example, in the present embodiment, the drive transmission shaft 9 passes through the inside of the cylindrical member 10 and forms this cylindrical shape. The member 10 is rotatably supported by the member 10. A transmission gear 21 that meshes with the transmission gear 22 of the roller rotation shaft 27 is provided on the reversing member 7 side of the drive transmission shaft 9 (see FIG. 2). A pulley 20 is fixed in the vicinity of the opposite shaft end. A belt 19 that transmits the rotational driving force of the transport driving source 11 is wound around the pulley 20. A thrust bearing 28 that receives the end face of the pulley 20 is provided at the end of the drive transmission shaft 9 on the pulley 20 side.
[0019]
The belt 19 is provided so as to transmit the rotational driving force of the transport driving source 11 to the drive transmission shaft 9 via the pulley 20. The conveyance drive source 11 may be taken out from a cylindrical conveyance roller 34 constituting the main conveyance unit, or may be taken out directly from a conveyance motor for driving the main conveyance unit. The power transmission path from the conveyance drive source 11 to the belt 19 will be described. First, the belt 13 is directly or indirectly wound around the conveyance motor to transmit the driving force of the conveyance motor (see FIG. 5). The belt 13 is wound around the pulley 14 and other pulleys. A transmission gear 15 is provided coaxially with the pulley 14 and rotates the same amount as the pulley 14 (see FIG. 4). Further, a transmission gear 16 meshing with the transmission gear 15 and a one-way clutch 17 meshing with the transmission gear 16 are provided (see FIGS. 4 and 5). The one-way clutch 17 is provided with gears 17a and 17b having the same diameter on the same axis, for example, and the output shaft 17c is united even if the gears 17a and 17b rotate in any direction by the operation of a clutch (not shown) provided therein. It is provided 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 pulley 20 described above (see FIGS. 3 and 6). In this 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 conveyance driving force of the conveyance driving source 11 is the conveyance driving 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 → Transmission gear 21 → transmission gear 22 → roller rotating shaft 27 → conveying 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 which direction the mechanism after the conveyance drive source 11 is rotated. For this reason, the rotation direction of the conveyance roller 23 is always constant.
[0021]
The operation of the card reverse conveyance mechanism of the present embodiment will be described.
[0022]
In order to convey the card 30 on the reversing member 7, the conveyance drive source 11 is driven to rotate the conveyance roller 23 so that the card 30 sandwiched between the conveyance roller 23 and the driven roller 24 is sent in one direction. To. Further, 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 sandwiched between the conveying roller 23 and the driven roller 24, even if the reversing member 7 is reversed in this state, it does not fall from the reversing member 7. The card 30 can be transported even when the reversing member 7 is rotated at any angle of 0 to 270 degrees (see FIGS. 8 to 11).
[0023]
In addition, the reversing motor 2 may be driven to reverse the reversing member 7 and change the direction while the card 30 is sandwiched. As a result, the reversing member 7 rotates within a range of 0 to 270 degrees while holding the card 30 (see FIGS. 8 to 11). However, at this time, the transmission gear 22 meshed with the transmission gear 21 revolves around the transmission gear 21 so that the transmission gear 22 itself rotates and rotates the transport roller 23 to feed the card 30. The position of the held card 30 may be shifted, and the card 30 may be dropped in some cases. Therefore, when the reversing member 7 is reversed, it is desirable to perform card position control in anticipation of the card shift amount accompanying the reversal amount. For example, when the amount of card displacement can be grasped, the displacement at the time of reversal is offset by preliminarily shifting the card 30 by the amount of the displacement toward the back side or the near side in the card transport direction. It is possible to hold at a desirable predetermined clamping position. Or you may make it eliminate the card | curd deviation amount at the time of inversion by rotating the drive transmission shaft 9 while inverting the inversion member 7. FIG. 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 influenced by the drive side, the stop side motor (reverse motor 2 or transport drive source 11 and The motor may be maintained in a non-rotatable brake mode.
[0024]
Further, according to the card reversing and conveying mechanism of the present embodiment, the card 30 held on the reversing member 7 in a stopped state can be shifted to the open side and taken out. At this time, the card 30 is pressed against the driven roller 24 side by the conveying roller 23, but when the card 30 is taken out, the card 30 is pressed against the driven roller 24 side and taken out to reduce the influence of the pressing by the driving roller 23. And 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 orientation of the card 30 and send it. Therefore, for example, various devices such as a printing device, an embossing device, and a card ejection device are preliminarily installed in a radial manner centering on the reversing member 7 according to the card type, printing process, and the like, and the cards 30 are distributed radially. The card can be ejected and each device can perform various processes.
[0026]
The above-described embodiment is an example of a preferred embodiment of the present invention, but is not limited thereto, and various modifications can be made without departing from the scope of the present invention. For example, in the present embodiment, the cylindrical member 10 is interposed between the sleeve 8 and the drive transmission shaft 9 to indirectly support the drive transmission shaft 9, and the end surface of the cylindrical member 10 is used for inversion. 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 using such a cylindrical member 10.
[0027]
【The invention's effect】
As is clear from the above description, according to the card reversing and conveying mechanism according to claim 1, the reversing member is cantilevered by the rotating body, and the conveying power of the conveying roller is transmitted by the drive transmission shaft coaxial with the rotating body. Since this is done, it is possible to open the non-supporting side of the reversing member. Therefore, the card held on the reversing member can be taken out in the direction perpendicular to the card conveying direction from the open side provided on the non-supporting side, and the card is laterally fed in the card issuing process in the card issuing device or the like. It becomes possible. For example, when a printer to which the card reverse conveying mechanism is applied and a magnetic card encoder are arranged in parallel, the card ejected from the printer can be directly slid laterally and sent to the magnetic card encoder side. Therefore, less space is required than when the paper 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 apparatus. In addition, variations in the configuration of the card issuing device can be increased.
[0028]
According to the card reversing and conveying mechanism according to claim 2, since the one-way clutch is provided between the conveying drive source and the drive transmission shaft so that the conveying roller is always rotated in a fixed direction, When reversed, it is possible to prevent a situation such as a card collision from occurring.
