By adjusting the gap with the belt 12, the number of sheets coming out can be adjusted depending on the size of the gap. It has become.

  The roller 18 is a paper feeding auxiliary roller that is pressed against the belt 12 by an appropriate pressure by the spring 17 and adjusts the conveying force of the paper that comes out, and also has a function of changing the discharge direction downward.

An embodiment corresponding to claim 4 will be described with reference to FIGS.

  A paper deflection sensor 20 is attached near the discharge port of the waste paper supply device. When the paper to be supplied is bent, it is detected and the paper discharge speed is reduced to synchronize with the paper processing speed of the shredder body. Yes.

  FIG. 1 shows an embodiment according to the present invention.

  The main body 1 is fixedly installed on the shredder main body 10, and has a built-in mechanism unit including a paper discharge control unit and a discharge roller 3. The paper storage box 2 is detachable from the main body 1 and is usually disposed at a waste paper collection site to store paper. The paper storage box 2 is provided with an opening 5 for storing paper, and the paper 24 is inserted into the inside through the opening 5 and stacked on the bottom of the paper storage box.

  When a certain amount of paper is stored in the paper storage box 2, it is transported to the main body 1 and installed at a predetermined position. The bottom of the paper storage box 2 is provided with a plurality of openings 17 through which the discharge rollers 3 enter. When installed in the main body, the discharge rollers 3 enter the inside of the paper storage box 2 and come into contact with the paper 24. It has become.

  When the paper storage box 2 is installed in the main body 1 and starts operating by an operation button or the like, the discharge roller 3 is rotated by an internal driving force to feed the paper toward the discharge port. The sheet separating plate 4 can be adjusted up and down with, for example, a high-friction rubber material, and the number of sheets ejected at a time can be adjusted by adjusting the gap between the discharge ports.

  The paper fed by the discharge roller 3 is conveyed through the paper guide 6 to the paper insertion port 8 of the shredder device. The shredder device operates automatically, sends the paper to the grinding blade 7 that rotates at high speed, and pulverizes it into fine paper pieces 9 for storage in the waste box 11.

  The paper storage box 2 has a lid fixed by a hinge 25 and is normally closed by a key or the like so that it can be opened as necessary.

  Another embodiment will be described with reference to FIGS.

  Inside the paper storage box 19, a control unit and a mechanism unit for paper conveyance are incorporated. The bottom of the paper storage box 19 is a belt paper transport device composed of a belt wheel 13 and a belt 12, and is rotated by the power of the motor 21 so that the stored paper can be transported from the bottom.

  The gears 15 and 22 transmit power to the paper separation roller 14 and the roller 18, and each element is connected by a crank 16 so that it can rotate to a certain extent around each fulcrum. The gap between the belt 14 and the belt 12 can also be adjusted.

  The rotation of the belt wheel 13 is transmitted as a reverse force to the paper separation roller 14 through the gears 15 and 22 and as a forward rotation force to the roller 18. Power is transmitted to the paper separation roller 14 through, for example, a torque limiter so that an excessive torque load at the time of paper separation is not directly transmitted to the power side.

  Since a part of the plurality of sheets conveyed by the belt 12 is held by the sheet separation roller 14, the number of sheets that are ejected at a time is adjusted, and the rollers 18 change the angle downward and are discharged. The spring 17 has a role of pressing the roller 18 against the belt 12 with an appropriate pressure, and always plays the role regardless of the position of the paper separation roller 14.

  The sensor 20 provided for detecting the sheet deflection is, for example, a general reflection type photoelectric sensor, and operates when the sheet approaches the deflection sensor side when the sheet supply speed of the main body is larger than the processing speed on the shredder apparatus side. When the sensor 20 is activated, the control unit decreases the rotation speed of the motor 14 and adjusts the paper supply speed.

The invention's effect

  According to the present invention, since the paper in the paper storage boxes installed in a plurality of dispersions is pulverized by one shredder capable of high-speed processing, the operating efficiency of the expensive shredder is dramatically improved and the total cost is reduced. It becomes. In particular, a shredder apparatus that holds paper fibers for a long time and is suitable for recycling has a high processing speed but is expensive. Therefore, the number of installation is greatly limited, but the present invention is very effective in effectively operating the shredder apparatus.

  Since paper storage boxes are cheap and can be installed on-site in the same way as ordinary trash cans, it is possible to thoroughly manage the confidentiality of documents that have been randomly thrown away in trash cans.
