JPH0680304A - Paper sheet stacking device - Google Patents

Abstract

PURPOSE:To detect difference between paper sheet amounts in two steps by one sensor, in the case of detecting the stacking amount of paper sheets. CONSTITUTION:Paper sheets 1 are held between a belt 3 hanging on a roller 2 so as to be carried in an arrow mark direction (a) and guided downward by a switch 4 so as to be stacked in a stacking box 5. When the paper sheets 6 reach a certain amount after continuing stacking, a lever 7 is pushed up and a sensor 8 is pushed up in an arrow mark (b) direction. Then, a first switch turns on and a second switch turns on when stacking is continued as it is.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper sheet stacking device,
In particular, the present invention relates to a paper sheet stacking device having a mechanism for detecting that the stacked paper sheets have reached a certain amount.

[0002]

2. Description of the Related Art In a conventional paper sheet stacking device of this type, as shown in FIG.
It is sandwiched between the sheets and conveyed in the direction of the arrow a, guided downward by the switch 4, and accumulated in the accumulation box 5. Paper sheets accumulated 6
When it reaches a constant amount, it contacts the lower surface of the lever 7, pushes up the lever 7 in the direction of the arrow b, and the sensor 9 connected to the lever 7 is also pushed up. When the sensor 9 is pushed up, the switch is turned on, and it can be detected that the paper sheet 6 has reached a certain amount.

[0003]

The above-mentioned conventional stacking apparatus detects when the paper sheets are full in the stacking box, so that the stacking is stopped immediately or the stacked paper sheets are taken out. Must-have. Also, if the sensor is adjusted to detect before it is full, it must be monitored until it is full.

[0004]

The paper sheet stacking device of the present invention is a paper sheet stacking mechanism having a sensor that switches the connection state by being pressed by the paper sheets stacked in a container. It is characterized in that it is provided with a switch whose connection is switched in a plurality of stages in accordance with the accumulation amount of the paper sheets.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIG. 1 is a side view of an embodiment of the present invention.
The paper sheet 1 is sandwiched by the belt 3 that is wound around the roller 2, and the arrow a
Is conveyed in the direction, is guided downward by the switch 4, and is accumulated in the accumulation box 5.

FIG. 2 is a perspective view of the sensor 8 of this embodiment. When the sheets 6 are stacked up to a certain amount in FIG. 1, the lever 7 is pushed up as shown by an arrow b, and is attached to the lever 7. The existing sensor 8 is pushed down in the direction of arrow c and first turned on to the contact 12 of the switch 10 to detect that the stacking box 5 is almost full. Paper sheets 6 as they are
If they are left without being taken out, they will continue to be accumulated and the inside of the accumulation box 5 will be full. At that time, the contact 13 of the switch 11 is turned on to detect that it is full.

[0008]

As described above, according to the present invention, by using a switch that is turned on in two steps for detecting the amount of accumulation, one sensor can detect two steps, that is, just before full and two full.
