The above-mentioned object of the present invention is to provide a paper sheet conveyance device having a conveyance path equipped with a plurality of sensors for detecting the passage and accumulation of paper sheets, and a switching gate for switching the conveyance direction of the paper sheets. This is achieved by a paper sheet conveying apparatus characterized in that it is provided with means for temporarily retracting the switching gate and means for conveying the conveyance path at a low speed in response to a signal for detecting paper sheet accumulation.

[Effect]

In the present invention, a plurality of sensors that detect the passage and accumulation of paper sheets detect the accumulation of paper sheets and the accumulation of paper sheets based on the paper conveyance speed.
A jam etc. is detected, and based on this result, the stepping motor for gate evacuation is operated to evacuate the switching gate from the conveyance section, and while the conveyance motor rotates at low speed, the paper sheets accumulated in the conveyance path are conveyed at low speed and conveyed to the next stage. It is to let them do so.

It is attached to the bracket. The bracket 47 is attached to the shaft 58, and the shaft 58 is supported by 31 bearings attached to the frames 52a and 52b. On the axis of the shaft 58 are a sensor plate 49b and a sensor plate 49 for detecting the fixed position of the switching gate 17b.
23 stepping motors are connected to drive the motor. Opposing the sensor plate 49b, the sensor plate 49b
A 48b fixed position detection sensor is attached to detect the fixed position of the machine. Further, 30 rollers integrated with 31 bearings are mounted on the axis of the shaft 58, contacting the roller 330, and being rotated by the rotation of the roller 33. The roller 33 is fixed to a shaft 59 and is driven by a drive source (not shown). A conveyor belt 29 is rotated by a conveyor roller 44, and a conveyor roller 43 is rotated by a conveyor belt 29. 28 is a conveyor belt which is rotated by rollers 45. , 60
is a tension roller which functions to adjust the tension of the conveyor belt 28. The conveyance rollers 44 and 45 are driven by a drive source (not shown).

34a and 34b are guides that help convey paper sheets;
Paper sheets are transferred to the downstream roller 33. It helps guide the user to the rollers 30.

The following is a second explanation of the operation of this embodiment configured as described above.
This will be explained using FIG. Paper sheets conveyed from the upstream Z direction are conveyed between the conveyor belts 28, 29, pass through the sensor sections 24, 25, 26, 27, and then reach the switching gate section 1.
7b. The switching gate 17b is controlled to switch the gate and pass the transport rollers 30, 33, or to transport downstream without switching the gate, depending on the determination result of the discrimination section described later. Further, the following explanation will describe the operation when gate switching is performed.

Normal paper sheets that have passed through the switching gate 17b pass between the sensor light receiving sections 53 and 54 in a predetermined time corresponding to the transport speed, and then pass between the transport rollers 30 and 33 while being guided by the guides 34a and 34b. However, paper sheets that are stacked in the stack section described later but are in bad shape, such as folded edges, half-rips in the center, or badly creased sheets, cannot properly pass through the switching gate I7b, which has a narrow gap, and are placed in the vicinity of the switching gate 17b. This causes a jam, and further increases the jam as it collides with subsequent paper sheets. The sensor light receiving sections 26, 27, and 53.54 detect the passage time of the paper sheet, and when the paper sheet remains for a predetermined time or more, the sensor drive circuit 36 detects a jam.

When a jam is detected, the control unit 40 stops the rotation of a transport motor (not shown) and stops the rotation of the transport path connected to the transport motor. Next, the control section 40 controls the stepping motor drive circuit 38. The stepping motor 23 is controlled to rotate by a predetermined number of rotations via the signal line 51. When the stepping motor 23 rotates by a predetermined number of rotations, the switching gate 17b is rotated by the conveyance roller 43. It retreats by a predetermined amount from the conveyance path constituted by the conveyor belt 29. This widens the gap between the switching gates 17b. Next, under the control of the control unit 40, the stopped conveyance motor (not shown) is rotated at low speed, and while the conveyance path linked thereto is rotated, the switching gate 1
At 7b, the jammed paper sheets are conveyed to the next stacking section, which will be described later. Jammed paper sheets conveyed to the stack section can be easily removed by the intervention of an attendant. The above describes a method for automatically transporting paper sheets that have jammed in the switching gate 17b to the next stage.
Jam release switch section 42 attached via 141
By pressing , the switching gate 17b can be retracted by a predetermined gap via the control section 40, the signal line 39, the stepping motor drive circuit 38, the signal M51, and the stepping motor 23 as described above.
