Description

  The present invention relates to a medium stacking apparatus including a holding medium take-out prevention mechanism due to electrostatic sticking.

Some devices that process media such as cards and tickets insert a plurality of media, perform predetermined processing on these media, and return them. In this type of apparatus, there is an apparatus that includes a superimposing device that emits after superimposing a plurality of media inside the apparatus so that a customer or an operator can receive a plurality of media at once (see, for example, Patent Document 1). .
In the conventional superimposing apparatus, a stopper is provided so as to be able to protrude and retract in the conveyance path of the medium conveyed by the belt. When the stopper is raised, the leading edge of the medium comes into contact with the stopper and stops, so that another medium conveyed later is superimposed on the previous medium that is stopped.

Here, when carrying out a predetermined process such as information recording by unloading the overlapped medium to the processing unit, the medium is unloaded to the processing unit one by one by rotation of a roller or a belt. At this time, the medium may be attracted to static electricity generated on the roller or the belt, and another medium may be taken out to the medium processing unit. If the medium is carried out to the wrong processing unit, it causes a conveyance abnormality or a processing abnormality. For this reason, the overlay apparatus is provided with means for preventing such a take-out phenomenon. As conventional take-out prevention means, there are those that use antistatic processed products for rollers and belts or use antistatic spray. In addition, when the medium is transported, there is a case in which the neutralization brush is brought into contact with the medium to prevent the medium from being charged, or the peeling plate is brought into contact with the medium to forcibly peel off.
JP-A-2005-85013

However, depending on the charged state of the medium or the belt, the medium may not be prevented from being adsorbed. It may be adsorbed on the member itself provided for peeling, and it is difficult to obtain a stable effect. When transporting the media (when the overlay function is disabled), the media is transported while the surface is rubbed by the stripping member in a configuration in which the stripping member that prevents electrostatic sticking is pushed away by the stiffness of the media itself. As a result, the surface of the medium is easily scratched, and the medium is easily clogged or skewed.
The present invention has been made in view of such circumstances, and its main object is to reliably prevent the medium from being taken out in a state where the medium is stuck due to static electricity.

  The present invention that solves the above problems is provided at one end of the first transport unit, the second transport unit, and the first and second transport units that transport the sheet-like medium. A medium delivery opening, a throw-in conveyance roller provided in contact with the medium at the other end of the first and second conveyance units and having a groove formed in the circumferential direction, and the second An overlap holding portion formed when the second transport portion is rotated with respect to the first transport portion with the one end side of the transport portion as a fulcrum, and a plurality of the media can be stacked. And a take-out prevention stopper that is disposed on the conveyance path of the medium while entering the groove of the throwing conveyance roller in a state where the superposition holding portion is formed. The device.

  In this medium superimposing device, when a take-out prevention stopper is arranged in the transport path, the end of the medium hits the take-out prevention stopper to prevent the medium from being taken out. When the medium is transported in a normal state, if the take-out prevention stopper is retracted from the transport path, contact between the take-out prevention stopper and the medium is prevented. When the medium is carried into the stacking holding unit, the medium is fed into the stacking holding unit so that the medium is sandwiched between the take-out prevention stopper and the throw-in transport roller arranged in the transport path.

According to the present invention, in the medium superimposing device according to claim 1, when the medium is overlapped, a discharge-side stopper capable of contacting the medium in the opening-side transport path can be moved forward and backward with respect to the transport path. It is characterized by being provided in.
In this medium superimposing apparatus, when the emission side stopper is disposed in the transport path, the medium is prevented from moving in the direction toward the opening, and the medium can be reliably collected. When ejecting the medium, if the ejection-side stopper is retracted from the conveyance path, contact between the ejection-side stopper and the medium is prevented, and ejection can be performed from the opening.

According to the present invention, in the medium stacking apparatus according to claim 1, the take-out prevention stopper is movable in a direction in which the medium is fed into the stack holding section, and the medium is moved from the stack holding section. It is provided so that it cannot move in the direction of carrying out.
In this medium superposing apparatus, when the medium sent to the superposition holding part is electrostatically attached to the transport part, the medium moves according to the driving of the transport part. The edge hits the take-out prevention stopper. The take-out prevention stopper does not prevent the transport unit from being driven, but does not allow the medium to move in this direction, so that the medium is detached from the transport unit.

  According to the present invention, since the take-out prevention stopper is provided so as to protrude and retract in the transport path, when the take-out prevention stopper is disposed in the transport path, it is possible to reliably prevent the medium from being taken out. When the second conveyance unit is opened with respect to the first conveyance unit to form the stacking holding unit, the medium is fed into the stacking holding unit so that the medium is sandwiched between the take-out prevention stopper and the throwing conveyance roller, thereby conveying It becomes possible to reliably feed the medium into the space formed by opening the part.

The drive connecting shaft 26 is connected to the rotating shaft of the roller 24 and can be rotated by a motor (not shown). As shown in FIG. 1, the three rollers 21 to 23 on the insertion port 3 side (hereinafter referred to as one end side) are positions substantially corresponding to the three rollers 13 to 15 of the lower transport unit 10 in the vertical direction. The medium is sandwiched and conveyed via the conveyor belts 16 and 25. In the upper transport unit 20, the roller 24 closest to the medium processing unit (hereinafter referred to as the other end) on the side opposite to the insertion port 3 is disposed at a position corresponding to the throwing transport roller 30 in the vertical direction. Yes.

  The throwing conveyance roller 30 is rotatably supported by a processing unit conveyance unit 31 provided on the other end side of the lower conveyance unit 10 and the upper conveyance unit 20. The processing unit conveyance unit 31 conveys a medium to each medium processing unit of the medium processing apparatus, and includes a plurality of rollers and a conveyance belt. As shown in FIG. 3, a groove 32 is provided in the thrown conveyance roller 30 along the circumferential direction at the approximate center in the rotation axis direction.

  A driving device 40 is provided at the bottom of the housing 2. The drive device 40 includes a solenoid and the like, and is configured to drive and control the link mechanism 41. The distal end portion of the link mechanism 41 enters the lower conveyance unit 10, and the emission side stopper 42 is fixed thereto. The ejection-side stopper 42 is rotatably attached to the housing 2 and is connected to the link mechanism 41. By driving the link mechanism 41, the first stopper 42 protrudes into the medium conveyance path in the vicinity of the roller 13. And a second position retracted from the transmission path.

  Further, the overlapping device 1 is provided with a moving mechanism 50 from the vicinity of the roller 22 of the upper transport unit 20 to the other end. The moving mechanism 50 has a superposition motor 51 fixed to the housing 2 above the roller 22. A superposition mechanism operating cam (hereinafter referred to as a cam) 52 is attached to the rotation shaft of the superposition motor 51. A bearing 53 that contacts the outer periphery of the cam 52 is disposed below the superposition motor 51. The bearing 53 is attached to the upper part of the overlapping lever 54. As shown in FIG. 4, the overlapping lever 54 has an arm portion 55 fixed to the overlapping arm 11 (see FIG. 1), and is rotatable around the rotation axis 12 </ b> A of the roller 12. Further, as shown in FIGS. 3 and 4, the end 54 </ b> A on the other end side of the overlapping lever 54 extends above the transport path. A take-out prevention stopper 56 is rotatably attached to the end portion 54A. The take-out prevention stopper 56 is urged by a return spring 57 and is in contact with the take-out prevention stopper regulating portion 58 in the no-load state. At this time, the lower end of the take-out prevention stopper 56 is slightly inclined toward the other end side from the vertically lower side. The stacking prevention stopper 56 has a width in a direction substantially perpendicular to the transport direction so as to be inserted into the groove 32 of the throwing transport roller 30. Note that the overlapping lever 54 is biased by a return spring (not shown) so that the take-out prevention stopper 56 comes to a position retracted from the conveyance path as an initial state.

Next, the operation of this embodiment will be described.
As shown in FIG. 1, when the lower transport unit 10 and the upper transport unit 20 are arranged in parallel, that is, when the overlapping function is disabled, the lower transport unit 10 follows the upper transport unit 20. Are arranged as follows. At this time, the ejection side stopper 42 is retracted to a second position below the conveyance path. The take-out prevention stopper 56 is retracted above the conveyance path. When the roller 24 of the upper transport unit 20 is rotated counterclockwise in FIG. 1 by the drive connecting shaft 26, the transport belt 25 rotates counterclockwise. The transport belt 16 of the lower transport unit 10 is rotated by the transport belt 25. The medium inserted from the insertion port 3 is sent to the other end so as to be sandwiched between the two transport units 10 and 20, and delivered to the processing unit transport unit 31. The processing unit conveyance unit 31 conveys the medium carried out by the roller 24 and the throwing conveyance roller 30 of the upper conveyance unit 20 to a medium processing unit suitable for the medium.

  When the medium is returned after a predetermined process is performed by a medium processing unit (not shown), the driving device 40 and the moving mechanism 50 are driven to enable the overlapping mechanism. More specifically, the superposition motor 51 rotates the cam 52. The bearing 53 is pressed downward by the cam 52. As shown in FIG. 5, the overlapping lever 54 rotates around the rotation shaft 12 </ b> A, and the lower end portion of the take-out prevention stopper 56 enters the groove 32 of the throwing conveyance roller 30. At this position, the take-out prevention stopper 56 is arranged in the transport path. At the same time, the lower conveying unit 10 rotates around the rotation shaft 12A together with the overlapping lever 54, and the lower conveying unit 10 opens with respect to the upper conveying unit 20 on the other end side, and the overlapping holding unit 60 is formed. Since the lower conveyance unit 10 is driven to rotate by being driven by the conveyance belt 25 of the upper conveyance unit 20, the conveyance belt 16 stops in the opened state. Further, the driving device 40 operates the link mechanism 41 to cause the emission side stopper 42 to protrude to the first position in the conveyance path.

  When the medium is returned from the medium processing unit through the processing unit transport unit 31, the end surface of the medium contacts the take-out prevention stopper 56. When the take-out prevention stopper 56 is pressed by the medium, the take-out prevention stopper 56 rotates in the direction indicated by the arrow in FIG. 4 and opens in the ejection direction. This allows passage of the medium. The take-out prevention stopper 56 is urged to return to the original position by the action of the return spring 57, so that the medium being conveyed is thrown and pressed against the conveyance roller 30. As a result, the medium is completely fed into the stacking holding unit 60 by the rotation of the throwing conveyance roller 30. After the medium is fed, the take-out prevention stopper 56 returns to the original position by the action of the return spring 57.

  Here, the medium sent to the stacking holding unit 60 may stick to the transport belt 25 of the upper transport unit 20 due to the action of static electricity or the like. When the drive connecting shaft 26 is rotated in this state to cause the transport belt 25 to rotate forward, the medium attached to the transport belt 25 comes into contact with a take-out prevention stopper 56 on the other end side of the transport path. The take-out prevention stopper 56 does not disturb the driving of the upper transport unit 20. However, the take-out prevention stopper 56 hits the take-out prevention stopper restricting portion 58 and does not move in the direction in which the medium is sent from the other end portion to the medium processing portion. For this reason, the medium is detached from the conveyance belt 25 and falls to the stacking holding unit 60.

  In addition, as a case where the upper conveyance unit 20 is rotated in the direction opposite to the ejection direction in a state where the medium is detained in the stacking reservation unit 60, there is a case where a plurality of processes are performed on the medium. For example, if the medium is a magnetic card, the medium processing unit punches the remaining amount as a guide, prints, writes data with the magnetic head, performs read verification, and then puts it in the overlay holding unit 60 Then, punch another number of magnetic cards previously held in the mechanism on the medium processing unit side by punching as a guide for the remaining amount one by one, printing, writing data with the magnetic head, and performing read verification After that, there is a case where it is put in the superposition holding part 60.

  When the necessary processing is completed for all the media, the ejection side stopper 42 is retracted from the conveyance path and the upper conveyance unit 20 is driven to eject the medium from the insertion port 3.

According to this embodiment, by rotating the upper transport unit 20 so as to open the lower transport unit 10, it is possible to form the stacking storage unit 60 that accumulates a plurality of media, and the other end. Since the take-out prevention stopper 56 is provided on the part side, the medium can be conveyed while being held between the take-out prevention stopper 56 and the throw-in conveyance roller 30. Since the stacking holding unit 60 is formed by lowering the lower transport unit 10, the medium cannot be transported so as to be sandwiched between the upper transport unit 20 and the lower transport unit 10. By transporting the medium so as to be sandwiched by the throw-in transport roller 30, the medium can be reliably sent to the stacking holding unit 60. Therefore, the medium can be reliably transported and stored in the overlapping storage unit 60 until it reaches the rear end.
Since the take-out prevention stopper 56 does not allow the medium to move in the direction from the stacking holding unit 60 to the medium processing unit, even if the medium causes electrostatic sticking to the upper transport unit 20, Therefore, it is possible to reliably prevent integration failure.
Since the ejection-side stopper 42 is provided in the transport path so as to be able to appear and retract, the medium can be reliably aligned with the stacking reservation unit 60. When the ejection-side stopper 42 or the take-out prevention stopper 56 is retracted from the conveyance path, the stoppers 42 and 56 do not come into contact with the medium, so that no skew of the medium, that is, no damage occurs. In addition, when the take-out prevention stopper 56 is in the transport path, the medium is only thrown and pressed to the transport roller 30 so that the surface of the medium is not damaged.

The present invention can be widely applied without being limited to the above-described embodiment.
For example, as a sheet-like medium, a magnetic card, a medium without a magnetic coating film, a ticket, an IC (Integrated Circuit) card, a combination thereof, or the like can be used.
The arrangement of the stoppers 42 and 56 and the conveying units 10 and 20 may be reversed upside down. These mechanisms may be arranged in an inclined manner. The groove 32 of the throwing conveyance roller 30 may be plural. In this case, the take-out prevention stopper 56 may enter only one of the plurality of grooves 32 or may be configured to enter the plurality of grooves 32.
