Description

  The present invention relates to a transport path switching device that switches a transport path for transporting paper sheets such as banknotes and forms, particularly in connection with a system for processing paper sheets.

  An example of a conventional paper sheet conveyance direction switching device is shown in FIG. This apparatus is a device for switching paper sheets conveyed from the conveyance path A to either one of the two directions of the conveyance path B or the conveyance path C. The apparatus transfers the paper sheets from the conveyance path A to the conveyance path B or C. A gate main body 101 as a gate means for switching the conveyance direction while conveying and guiding, a rotating shaft 102 as a supporting means to which the gate main body is fixedly attached, and a rotating shaft connected to the rotating shaft are necessary for switching the conveying path. Link mechanisms 103, 104, and 105 for rotating the rotation shaft by a predetermined angle, solenoid means 106 and spring means 107 as drive sources for driving the link mechanism 103, and stop means (not shown) for stopping the rotation shaft at a predetermined angle. It is configured.

  In this paper sheet conveyance direction switching device, when a paper sheet is conveyed from the conveyance path A to the conveyance path B, a predetermined voltage is applied to the solenoid 106 so that the gate body 101 is positioned at a position shown by a solid line in FIG. When the paper sheet is transported from the transport path A to the transport path C, the gate body 101 is reversely rotated by the restoring force of the spring 107 without applying a voltage to the solenoid 106. In this way, the gate body 101 is positioned at the position shown by the broken line in FIG. 4 by the stopping means, and the transport direction of the sheets is thus switched.

  FIG. 5 shows a conventional example of switching the sheet transport direction in three directions. This device is a device that switches the conveyance direction while conveying and guiding bills from the conveyance path A to the conveyance path B or the conveyance path C or from the conveyance path B to the conveyance path A or the conveyance path C. A gate main body 101 as a gate means for switching the conveyance direction while guiding, a rotating shaft 102 as a supporting means to which the gate main body 101 is fixedly attached, and a stepping motor 108 as a drive source connected to the rotating shaft. It is comprised from.

  In this three-direction paper sheet conveyance direction switching device, the number of steps of the stepping motor 108 is controlled by a predetermined angle so that the gate main body 101 comes to a position necessary for switching the conveyance path. The paper transport direction was switched.

  In the first conventional example, paper sheets can be switched only in two directions. For this reason, in order to switch paper sheets in three directions, another similar transport path switching device is required, and there is a problem that the switching mechanism becomes large.

  As another problem, there is a problem that the gate main body cannot be stopped at three locations even if only the gate main body has a shape that can be conveyed and guided in three directions.

  In the apparatus for switching the conveyance path in the three directions of the second conventional example, the paper sheets can be switched in the three directions. However, since the stepping motor is used as the drive source, if the switching operation becomes fast, a step out occurs when the gate body is driven, and the gate body does not rotate at a predetermined angle, so that the sheet switching error occurs at the switching unit. In addition, there is a problem that a conveyance jam easily occurs due to a switching failure. Further, in order to keep the gate main body at a predetermined position, it is necessary to continuously excite the stepping motor, which causes a problem in terms of power saving.

  In order to solve the above problems, one gate means having a function of switching the conveyance direction from one conveyance path to another conveyance path while conveying and guiding the paper sheet, and the gate means are fixedly attached. Rotating shaft means, a bracket fixedly attached to the rotating shaft means, a pin attached to a part of the bracket, a link means that is rotatable with respect to the pin, and a gate attached to the link means. A drive source for driving the means, a spring means having one end attached to a part of the bracket, a stop member means attached to be in contact with a part of the bracket, and a rotating shaft for rotating the stop member means Means, a pin attached to a part of the rotating shaft means, and a link means that is rotatable with respect to the pin, and is connected to the link means. It is provided with a driving source for driving the stop member.

  According to the present invention, it is possible to realize a paper sheet conveyance direction switching device in three directions that is compact and highly reliable.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a view showing an embodiment of an apparatus for switching the transport direction of paper sheets of the present invention. In this embodiment, the apparatus for switching the conveyance direction is configured such that the sheet is transferred from the first sheet conveyance path A to the second sheet conveyance path B, which is composed of a belt and a roller indicated by broken lines in FIG. Operation for switching the transport direction, operation for switching the transport direction of the paper sheet from the first transport path A to the third transport path C, and transport direction of the paper sheet from the second transport path B to the first transport path A And the operation of switching the transport direction of the paper sheet from the second transport path B to the third transport path C are shown.

  The sheet conveyance direction switching device in this embodiment is a gate body 1 and gate body as one gate means having a function of switching the conveyance direction from one conveyance path to another conveyance path while conveying and guiding the sheet. Is fixedly attached to the rotating shaft 2, the bracket 3 fixedly attached to the rotating shaft 2, the pin 4 attached to a part of the bracket 3, and the link that moves rotatably with respect to the pin 4. 5, a solenoid 6 as a drive source that is connected to the link 5 and drives the gate body, a coil spring 7 having one end attached to a part of the bracket 3 and the other end attached to a frame (not shown), Attached to a stop member 8 attached so as to be in contact with a part of the bracket 3, a rotating shaft 9 for rotating the stop member 8, and a part of the rotating shaft 9 Pin 10, a link 11 that is rotatable with respect to the pin 10, a solenoid 12 that is connected to the link 11 and is attached to drive the stop member, and one end of a part of the stop member 8. The coil spring 13 is attached and the other end is attached to a frame (not shown).

  Next, the operation of the paper sheet transport direction switching device of this embodiment will be described.

  When a paper sheet is transported from the transport path A to the transport path B, the gate body 1 of the transport direction switching device is stopped at a position indicated by a solid line in FIG. At this time, no voltage is applied to the solenoid 6 that drives the gate body 1 and the solenoid 12 that drives the stop member 8. For this reason, only the moment in the clockwise direction in the figure acts on the gate body 1 by the restoring force of the coil spring 7, and the gate body 1 rotates in the clockwise direction around the rotation axis 2.

  On the other hand, since no voltage is applied to the solenoid that drives the stop member 8 at this time, only the moment in the clockwise direction in FIG. It rotates clockwise around 9 and stops at the position shown in FIG. 1 by a stopper (not shown).

  Since the stop member 8 is thus stopped at the position shown in FIG. 1, a part of the bracket 3 attached to the rotating shaft 2 that rotates together with the gate body 1 comes into contact with the stop member 8, thereby rotating. The gate main body 1 stops at the position shown in FIG. The bracket 3 is shaped so as to contact the stop member 8.

  When transporting a paper sheet from the transport path A to the transport path C, the gate body 2 of the transport direction switching device is stopped at the position indicated by the solid line in FIG. At this time, a voltage is applied to the solenoid 6 that drives the gate body 1 in order to drive the gate body 1, but no voltage is applied to the solenoid 12 that drives the stop member 8. For this reason, the gate main body 1 acts in the counterclockwise direction in the figure to overcome the restoring force of the coil spring 7, and the gate main body 1 rotates counterclockwise around the rotation axis 2. And it stops at the position of the continuous line of FIG. 2 by the stopper which is not illustrated.

  On the other hand, since no voltage is applied to the solenoid that drives the stop member 8 at this time, only the moment in the clockwise direction in the figure acts on the stop member 8 by the restoring force of the coil spring 13 as in FIG. The stop member 8 rotates clockwise around the rotation shaft 9 and remains stopped at the position shown in FIG. 2 by a stopper (not shown).

As described above, the stop member 8 remains stopped at the position shown in FIG. 2, and the bracket 3 attached to the rotating shaft 2 rotating together with the gate body 1 rotates counterclockwise, whereby the bracket 3 is stopped. No contact with 8.
When the paper sheet is transported from the transport path B to the transport path C, the gate body 1 of the transport direction switching device is stopped at the position indicated by the solid line in FIG. At this time, no voltage is applied to the solenoid 6 that drives the gate body 1, but a voltage is applied to the solenoid 12 that drives the stop member 8. For this reason, a moment in the clockwise direction in the figure acts on the gate body 1 by the restoring force of the coil spring 7, and the gate body 1 tries to rotate in the clockwise direction around the rotation axis 2.

  On the other hand, at this time, a voltage is also applied to the solenoid that drives the stop member 8, and a moment in the counterclockwise direction in the figure that overcomes the restoring force of the coil spring 13 acts on the stop member 8, and the stop member 8 rotates. It rotates clockwise around the shaft 9 and stops at a position indicated by a solid line in FIG. 3 by a stopper (not shown).

  As described above, when the stop member 8 is rotated to the position shown in FIG. 3 and stopped, the gate body 1 rotates in the clockwise direction larger than the position shown in FIG. A part of the bracket 3 attached to the rotary shaft 2 comes into contact with the stop member 8 so that the gate body 1 stops at the position shown in FIG. As in the case of FIG. 1, the bracket 3 is shaped so as to contact the stop member 8.

  When transporting paper sheets from transport path B to transport path A, the gate is the same as when transporting paper sheets from transport path A to transport path B shown in FIG. That is, the gate body 1 of the transport direction switching device is stopped at the position indicated by the solid line in FIG. At this time, no voltage is applied to the solenoid 6 that drives the gate body 1 and the solenoid 12 that drives the stop member 8. For this reason, only the moment in the clockwise direction in the figure acts on the gate body 1 by the restoring force of the coil spring 7, and the gate body 1 rotates in the clockwise direction around the rotation axis 2.

  On the other hand, since no voltage is applied to the solenoid that drives the stop member 8 at this time, only the moment in the clockwise direction in FIG. It rotates clockwise around 9 and stops at the position shown in FIG. 1 by a stopper (not shown).

  Since the stop member 8 is thus stopped at the position shown in FIG. 1, a part of the bracket 3 attached to the rotating shaft 2 that rotates together with the gate body 1 comes into contact with the stop member 8, thereby rotating. The gate main body 1 stops at the position shown in FIG.

  By configuring and driving the switching device as described above, it is possible to switch the sheet transport direction to three directions. In the above embodiment, the transport direction of the paper sheets in the case shown in FIG. 3 is opposite to that shown in FIGS. 1 and 2, but the transport paths A, B, and C are thus in the forward and reverse directions. Of course, it is the structure which can convey a paper sheet.

  Further, the gate means shown in the present embodiment, the rotating shaft means to which the gate means is fixedly attached, the bracket fixedly attached to the rotating shaft means and the pin attached to a part of the bracket, And a link means that is rotatable with respect to the pin, a drive source that is connected to the link means and drives the gate means, a spring means having one end attached to a part of the bracket, and a part of the bracket Stop member means attached so as to come into contact, rotation shaft means for rotation of the stop member means, a pin attached to a part of the rotation shaft means, and a link means that is rotatable with respect to the pin, The drive source connected to the link means and driving the stop member is limited to the means shown here as long as it has a similar function. No it is a matter of course.
