Description

[Detailed Description of the Invention] The present invention relates to a paper sheet sorting and stacking device that sorts and stacks conveyed paper sheets.

2. Description of the Related Art Conventionally, a paper sheet processing apparatus is known in which a sorter for sorting paper sheets and a stacking device are separately arranged on a conveyance path. Therefore, the above-mentioned stacking device utilizes the tension of a spring or the like as a means of increasing the stacking density of paper sheets to constantly apply a pressing force to the stacked paper sheets. Therefore, a roller device or the like is required to forcibly feed the paper sheets accumulated in the stacking section against the pressing force. Moreover, there is a drawback that it is difficult to employ the above-mentioned method when the paper sheets to be conveyed are weak.

In addition, the amount of accumulated paper sheets was detected using the weight of the paper sheets accumulated in the stacking section or a pressure device installed in the stacking section, but this method had problems with the structure, cost, detection accuracy, etc. .

The present invention was developed in view of the above circumstances, and its purpose is to have a relatively simple structure, but with functions for sorting paper sheets, increasing the density of stacking, and detecting the amount of stacking. It is an object of the present invention to provide a paper sheet sorting and stacking device from which paper sheets can be easily taken out.

The present invention will be explained below based on an embodiment shown in FIGS. 1 to 3. In FIGS. 1 and 2, paper sheets P processed in a processing section at a front stage (not shown) are held and conveyed in the direction of arrow A by a pair of carry-in belts 1, and passed through a sorting device 2 to a stage provided at a rear stage. It is delivered to a pair of delivery belts 3, and is gripped and transported in the direction of arrow B. Therefore, the sorting device 2 has a rotary solenoid 4 whose excitation is controlled according to a signal based on the content of the processing of the paper sheets P in the processing section at the previous stage, and a rotary solenoid 4 that is perpendicular to the axis 5 of the rotary solenoid 4. a lever 8 whose base end is fixed to the shaft 5 at a constant angle with respect to the flapper 6 and a spring 7 is tensioned at the free end; The first detector 9 detects the position. Further, a storage box 10 is provided below the flapper 6. Fratupa 6
By rotating, the sorted paper sheets P are stacked horizontally. Furthermore, the above storage box 1
A second detector 11 is disposed on one side wall of 0, that is, on the carry-in belt 1 side, and generates an output when the storage box 10 is pulled out in the direction of arrow C and when it is being pulled out. Therefore, the rotary solenoid 4 is deenergized. Therefore, the flapper 6 is returned to the position 6'' shown by the dashed line in FIG. 2 under the tension of the spring 7. In FIG. This is a control circuit that controls the excitation of the rotary solenoid 4 based on the output signal from the detector 11.

Next, the operation of the present invention based on the above configuration will be explained. Now, when paper sheets P that have passed through the processing section in the previous stage are picked up and conveyed in the direction of arrow A by the carry-in belt 1, a signal based on the content processed in the processing section is transmitted to the rotary solenoid 4, and the rotary solenoid - Since the excitation of the solenoid 4 is controlled, the flapper 6 integrally formed on the shaft 5 of the rotary solenoid 4 rotates in the arrow x or y direction, and the conveyance direction of the conveyed paper sheet P is rotated. Specify. That is, in the normal state and when transferring paper sheets P in the direction of arrow B, the flapper 6 rotates in the direction of arrow x by energizing the rotary solenoid 4, and transfers the paper sheets P accumulated in the storage box 10. Press the top of P. (6 shown in Figure 2,
On the other hand, when stacking the paper sheets P in the storage box 10, the rotary solenoid 4 is de-energized so that the flapper 6 rotates in the direction of the arrow y under the tension of the spring 7, and the second Since the paper sheet P is set at the position 6' shown in the figure, the paper sheets P are guided by the flapper 6 and stacked in the storage box 10 in a horizontal state.
Since the rotary solenoid 4 is energized again after a predetermined period of time, the flapper 6 returns to the position 6 or 6' shown in FIG. The pressure is applied quickly to improve the stacking density.

In this way, the flapper 6 is connected to the storage box 10.
When the accumulated amount of paper sheets P is pushed up in the direction of the arrow y and reaches a set value or more, the lever 8 fixed coaxially at a predetermined angle with the flapper 6 also moves in the direction of the arrow y at the same time. Since the first detector 9 is operated by the first detector 9, the amount of paper sheets P accumulated in the storage box 10 can be detected based on the output signal of the first detector 9.

Further, when the storage box 10 is set at a predetermined position, the second detector 11 is in an OFF state, and when the storage box 10 is pulled out in the direction of arrow C, the second detector 11 is activated. Since the rotary solenoid 4 is deenergized by this output, the flapper 6 is returned to the 6'' position shown by the dashed line in FIG. 2 under the tension of the spring 7.

Therefore, the flapper 6 is rotated upward from the state where it presses the paper sheets P accumulated in the storage box 10 and is separated from the paper sheets, and when the storage box 10 is pulled out, the paper sheets P are pushed against the flapper. It is possible to prevent the inconvenience of being dragged by the robot and falling backwards.

As explained above, according to the present invention, in addition to the original sorting which is the function of the flapper, it is also possible to improve the accumulation density of paper sheets accumulated in the storage box and also to detect the accumulation amount. In addition, when compared with the conventional method of detecting the amount of accumulated paper sheets based on the weight of the accumulated paper sheets, the accumulated amount of paper sheets falls from the storage box without being affected by the light weight of the paper sheets. It has the advantage that it can be detected earlier. Furthermore, it has excellent effects such as a simple structure, multifunctionality, improved assemblability, improved reliability, and low cost.
