[Detailed description of the device]

[0001]

[Industrial applications]

 According to the present invention, since the paper sheets discharged from the upstream device are taken into the post-processing device in one of two directions set, the downstream side of the take-in roller provided at the take-in port is considered. The present invention relates to a paper sheet fetching device having a switching gate for switching a fetching direction.

[0002]

[Prior art]

 1 to 3 show a paper sheet fetching device according to a conventional example. FIG. 1 is a cross-sectional view showing a state in which a paper sheet is taken in in the A direction out of two directions A and B, FIG. 2 is a cross-sectional view showing a state in which a paper sheet is taken in in the B direction, and FIG. FIG. 6 is a partial perspective view showing an example of a structure of a roller and a switching gate.

Reference numerals 1 and 2 in FIGS. 1 and 2 denote inlets for taking in the paper sheets P discharged from the upstream device, and reference numeral 2 denotes an upper roller 3 and a lower roller 4 which are arranged and opposed at equal intervals in the axial direction. The take-in rollers 5 are switching gates provided adjacently to the downstream side of the take-in roller 2, and as shown in FIG. Correspondingly arranged and fixed, a drive unit 7 such as a solenoid is connected to the support shaft 6. When the paper sheet P from the upstream device is taken in the A direction by this paper sheet taking-in device, when the take-in direction designating button "A" provided on the operation panel (not shown) is pressed, As shown in FIG. 1, the control unit (not shown) causes the drive unit 7 to rotate the switching gate 5 in the counterclockwise direction, and when the take-in direction designation button “B” is pressed, the result shown in FIG. As shown in the figure, the control unit causes the drive unit 7 to rotate the switching gate 7 in the clockwise direction.

In this way, when the taking-in direction is designated as the A-direction, as shown in FIG. 1, the path in the B-direction is blocked through the switching gate 5 which is being rotated in the counterclockwise direction during that time, and the paper sheet is closed. The class P is guided in the A direction so as to be stacked on the tray 8.

On the other hand, when the take-in direction is designated as the B direction, as shown in FIG. 2, the path in the A direction is blocked through the switching gate 5 which is being rotated in the clockwise direction during that time, and the paper sheet is cut. The class P is guided in the B direction and discharged to the tray 10 by the discharge roller 9.

[0006]

[Problems to be solved by the device]

 As described above, in the conventional paper sheet taking-in device, the switching gate is rotated to the predetermined side corresponding to the designated taking-in direction and fixed until another taking-in direction is designated. . Therefore, a free space 11 is provided between the switching gate 5 and the tray 8 as in the case of taking in the direction A by the switching gate 5, and the sheets are stacked on the tray 8 through the free space. When the paper fed out from the take-in roller 3 has a weak stiffness, the paper is curled immediately after being guided to the switching gate, and is turned over or buckled, and The flight of the leaves was not good, which could cause jams. Such curling, reversing and buckling of the paper sheets are inconvenient because they interfere with post-processing such as alignment, binding and sealing of the stacked paper sheets.

The present invention solves the above-mentioned drawbacks of the conventional apparatus and improves the straight flight of the paper sheet by using the switching gate for switching the capturing direction, so that the capturing can be performed smoothly and surely. It is an object of the present invention to provide a paper sheet uptake device adapted to be opened.

[0008]

[Means for Solving the Problems]

 In order to achieve this object, the present invention is directed to a paper sheet intake device for stacking paper sheets discharged from an upstream device on a tray in at least one direction in two directions through a free space. The take-in roller provided on the upper side, the switching gate provided on the downstream side of the take-up roller for rotating and switching the taking-in direction between two directions, and the leading edge of the paper sheet discharged from the upstream device has passed through the change-over gate. A sensor for detecting such a situation, a drive unit for rotating the switching gate, and a control unit for controlling the rotation direction of the drive unit so as to set the capturing direction by the switching gate to the first direction and the second direction. The control unit causes the drive unit to rotate in the second intake direction based on the passage detection signal from the sensor when the intake direction is set to at least the first direction. It is characterized by

[0009]

[Action]

 When at least one capture direction is specified, the control unit controls the drive unit when a signal that the sensor detects that the sheets to be captured have passed the tip of the switching gate is input. , Rotate the switching gate in the other direction. As a result, the switching gate is moved to the B-direction take-in position while the paper sheet is being taken in the A direction, so that the switching gate forms a wave in the traveling direction, that is, a corrugate. As a result, the stiffness of the taken-in paper sheets is strengthened, so that the flight performance in the free space formed on the downstream side of the switching gate is improved, and the paper sheets are reliably advanced in the A direction.

【Example】

 Hereinafter, an embodiment of the present invention will be described with reference to the drawings of FIGS. The same members as those in the conventional example shown in FIGS. 1 to 3 are designated by the same reference numerals, and a duplicate description will be omitted.

FIG. 4 is a cross-sectional view for explaining the operation of the switching gate at the time of taking in the direction A by causing the free gate provided on the downstream side of the switching gate to fly over the tray, and FIG. The position when the take-in direction is designated is shown, and (b) shows the position of the switching gate during the taking-in of sheets. Further, FIG. 5 is a sectional view taken along line AA of FIG.

In the paper sheet pick-up device according to the present invention, a sensor for detecting that the paper sheet taken in by the take-in roller near the downstream side of the take-in roller 2 has passed the tip of the switching gate. 12 are provided. In particular, the tray 8 aligns the paper sheets taken in on the tray, binds them with a stapler, or just aligns them without binding them, and transfers them to a sealing part provided on the downstream side. Is used.

Further, in the paper sheet fetching device according to the present invention, in order to achieve the object of the present invention, a control unit for controlling the driving unit 7 is provided on an operation panel (not shown) of the device. The drive unit 7 is driven in the following manner based on the input from the A-direction designating button among the direction-designating buttons and the input of the detection signal from the sensor 12.

That is, when the A direction designation button is pressed, the control unit causes the drive unit 7 to rotate in the counterclockwise direction as shown in FIG. Wait for paper sheet P to enter from the upstream device. Then, when the front end of the paper sheet taken in by the take-in roller 3 has passed the sensor 12, that is, when it is detected that the paper sheet P has passed the front end of the switching gate 5, it is detected from the sensor. Based on the input of the detection signal, the control unit causes the drive unit 7 to rotate the switching gate 5 in the clockwise direction as shown in FIG. As a result, as shown in FIG. 5, the switching gate 5 comes into contact with the paper sheet P taken in by the take-in roller 3 and forms a corrugate projecting downward at the abutting portion. Since the waist of the paper sheet is reinforced by this, the straight flight performance of the paper sheet P is improved, and the paper sheet P can fly far in the free space 11 and reach a desired position on the upper surface of the tray 8. They are aligned and loaded.

If desired, even when the take-in direction is designated as B, if the switching gate is rotated counterclockwise when the leading edge of the paper sheet is detected by the sensor 12, Even when the leaves are taken in in the B direction, it is possible to strengthen the waist of the paper sheets and improve the flight property to the tray 10 side.

[0016]

[Effect of device]

 As described above, according to the present invention, when the paper sheet is taken in one direction, the switching gate is rotated to the position when the paper sheet is taken in the other direction. Since the corrugates are formed on the paper sheets to be reinforced to strengthen the waist, it is possible to improve the straight flight performance of the paper sheets in the free space.
