As described above, in the present invention, the supply unit 20 adopts a motor driving method, for the following reasons.

Conventionally, using the elasticity of the spring, the plate 21 is adopted to push the paper to push the paper waiting to be inserted,

When the thickness of the sheets waiting to be loaded changes, the elastic force of the spring is changed so that the plate 21 cannot push the sheets waiting to be loaded at a constant pressure,

In particular, when there are few papers waiting to be loaded, the elastic force of the spring is drastically reduced, which makes it difficult to insert the paper smoothly.

In addition, in order to solve the problem as described above, there is a problem in that workability is inferior due to the inconvenience that the worker waiting to supply a certain amount of paper regularly to maintain the elastic force by the spring.

Therefore, according to the present invention, the push plate 21 is always pushed at a constant pressure by the driving of the operation motor 27a of the supply unit 20 as described above, so that the paper regardless of the thickness of the remaining ballot papers (S) It is possible to improve the workability of the operation can be smoothly.

This operation motor 27a is to rotate without being stopped at a constant speed so that the plate 21 has a constant pressure,

In this case, all of the ballot papers (S) waiting to be put are put in and the plate 21 is brought into contact with the support 5 to stop, or all of the waiting ballots (S) are put in to supply new ballots (S). Move the plate 21 in a direction opposite to the pressure direction (hereinafter referred to as a 'push direction'),

Or to prevent the overload is transmitted to the operating unit 27 during abnormal operation of the plate 21, such as when the external force applied by the abnormal force acts more than the pressure of the plate 21.

That is, the second torque limiter 25 includes a second driving body 25a connected by the operating motor 27a, the pulley P, and the timing belt B1 as described above;

It is comprised in the 2nd drive body 25b provided in the said 2nd drive body 25a, and connected with the said 1st rotation shaft 23a.

First, when the close plate 21 is in normal operation, the second driving member 25a and the second driven member 25b are connected to transmit the rotational force of the operating motor 27a to the first rotation shaft 23a.

At this time, the first rotating shaft 23a is rotated forward to push the ballot paper (S) waiting to be put at a constant pressure push plate 21 in the push direction.

However, in the case where the plate 21 has an abnormal operation

The first rotary shaft 23a stops when the plate 21 stops, and when the plate 21 moves in a direction opposite to the push direction, reverse rotation is applied.

At this time, when the second torque limiter 25, the second driving member 25a and the second driven member 25b are connected as in the normal operation, the rotational force in the reverse direction is transmitted to the operating motor 27a that rotates forward. Thus, the operating motor 27a is overloaded.

Accordingly, the second driving body 25a and the second driven body 25b of the second torque limiter 25 are separated from each other during abnormal operation of the close plate 21, thereby preventing overload of the operating motor 27a. By protecting the operating motor (27a) it is possible to ensure the stability and reliability of the device.

In FIG. 1, the counter 90 is provided at the inlet side of each stacker 50 to display the number of ballot papers S accommodated in each stacker 50.

In this case, the counting of the ballot paper S accommodated in each stacker 50 calculates and transmits the information in which the controller 10 is data to the counter 90,

At this time, the seven segments 91 can display the transmitted information numerically.

In addition to the seven segments, the display of the number of ballots in the counter may be replaced with display means for display such as an LED and the like.

And the supply unit and the pulley and timing belt and belt for transmitting power in the position adjusting unit according to the present invention, although not shown in the accompanying drawings, it is possible to replace the power transmission means such as sprockets and chains, gears, etc. ,

In addition, each of the transfer rollers is provided with a friction member having elasticity, such as rubber, elastomer, etc. It is preferable to increase the contact force with the ballot paper to facilitate the transfer of the ballot paper.

Furthermore, the supply unit and the position adjusting unit according to the present invention may be used in place of an actuator such as an LM guide instead of the same motor driving method as described above.

In addition, it is also possible to use various types of power transmission means.

In addition, the first and second torque limiters according to the present invention are of the type known in the art, it is possible to use those having a variety of operating mechanisms,

Although not shown in the accompanying drawings, the driving body and the driven body of the respective torque limiter block the overload transmitted to the motor by a conventional operating mechanism such as a friction lining slip method or a ball bearing disengagement method when overloading.

In describing the paper sorting apparatus of the present invention with reference to the accompanying drawings, the present invention has been described based on a specific shape and direction, but the present invention can be variously modified and changed by those skilled in the art, and such variations and modifications are within the scope of the present invention.
