DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a processing apparatus for disposing of an enormous amount of waste paper generated in government offices and offices.

[0002]

2. Description of the Related Art A huge amount of waste paper is generated every day in government offices and offices, but it is difficult to discard it mainly for security reasons. Is the reality. As a method for treating such waste paper, incineration or shredding is usually performed. However, the incineration method is not applicable in suburban areas, and in the city center, each office cannot be equipped with a small incinerator because of safety and smoke exhaust treatment, and the disposal of waste paper is usually cut by shredders. It is up to you.

[0003]

The shredder cuts the waste paper into small pieces so that characters and the like written on the waste paper cannot be read. Although it is a method, since the fibers of the waste paper are cut at the same time, it is difficult to use the waste paper after cutting as a raw material of the recycled paper. Another disadvantage is that the volume of the waste paper increases due to the cutting, and the disposal of the waste paper after the cutting is not easy.

The present invention has been made in order to solve the above-mentioned problems of the conventional waste paper processing by cutting, and is thorough in terms of maintaining confidentiality, and the waste paper after processing can be used as a raw material of recycled paper. It is an object of the present invention to provide an effective waste paper processing apparatus.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, a waste paper processing apparatus according to the present invention is provided for softening a waste paper by infiltrating a liquid into the waste paper and for making the waste paper into small pieces. Means, and means for molding the small piece of waste paper into small blocks. In order to rapidly penetrate and soften the liquid into the waste paper, a surfactant is used in the treatment liquid. Alternatively, water or a surfactant may be used as the treatment liquid, and ultrasonic waves may be oscillated in the liquid. A stirrer is used to make the softened waste paper into small pieces.

[0006]

[Function] There are two types of paper, one having good water absorption and the other having poor water absorption. Generally, paper having poor water absorption is often used for confidential paper and office paper. Therefore, simply immersing the waste paper in water requires a long time for the water to permeate the waste paper, and even if the water permeates, the waste paper is simply wetted and hardly loosened. Therefore, characters on the surface of the waste paper can be seen through, and there remains a problem in terms of maintaining confidentiality.

In this respect, the waste paper processing apparatus according to the present invention comprises:
Since a surfactant is used for the treatment liquid or ultrasonic waves are used, the liquid can permeate and soften the waste paper in a short time. Furthermore, since the pieces are loosened into small pieces by the stirrer, characters on the surface of the waste paper disappear, which is perfect in terms of maintaining confidentiality. Even if the waste paper is softened into small pieces, the fibers are not cut, so that it is effective as a raw material for recycled paper. Furthermore, since there is provided a means for molding the waste paper after loosening into a small block, the waste paper after treatment is not bulky and is easy to handle.

Embodiment 1 FIG. 1 is a front sectional view of a waste paper processing apparatus according to an embodiment of the present invention, FIGS. 2 and 3 are side views, and FIG. 4 is a plan view. In the drawing, 1 is a casing, 2 is a waste paper insertion table, 3 is a waste paper feeder, 4 is a liquid tank, 5 is a stirrer, 6 is a drop port, 7 is a feeder, 8 is a press cylinder, 9 is a press plate, 10 Is an extrusion plate, 11 is a bucket, 12 is a pump, 13 is a processing liquid, 1
4 is a level switch, 15 is a cover, 16 is a press container, 17 is a tray, 18 is a processing liquid tank, 20 and 21 are hydraulic cylinders, and 22 is a block of waste paper. As shown in the figure, the waste paper processing apparatus according to the present invention has a waste paper insertion table provided with a waste paper feeder 3 and a stirrer 5 disposed at the bottom of the waste paper insertion table at the bottom. A block manufacturing machine including a liquid tank 4, a feeder 7 connected to a drop port 6 below the liquid tank 4, a cylinder 8, a holding plate 9, and an extrusion plate 10;
A bucket 11 arranged below the block manufacturing machine, a processing liquid tank 18 for storing the processing liquid 13, and a pump 12 for supplying the processing liquid in the processing liquid tank 18 to the liquid tank 4 are housed in the casing 1. It is configured.

Next, the operation will be described. When processing the waste paper, the cover 15 of the processing apparatus is opened, the waste paper is placed on the insertion table 2 in an overlapping manner, and the cover 15 is closed. Stirrer 5
When it is determined that there is more room for loading waste paper in the liquid tank 4 based on the load current of
The above-mentioned waste paper is charged into the liquid tank 4 by one or two sheets. The waste paper charged into the liquid tank 4 is softened by the permeation of the treatment liquid 13 and further loosened by the swirling flow generated by the stirring of the stirrer 5 in the liquid tank and the blades of the stirrer 5 to be cut into small pieces. Become. The waste paper in the liquid tank, which has been turned into small pieces, is charged into the press container 16 of the block manufacturing machine via the dropper 6 at the lower part of the liquid tank 4 and the feeder 7 which is constantly rotating. The load current of the feeder 7 is checked, and when it is detected that the amount of waste paper in the press container 16 has reached a predetermined amount, the press cylinder 8 operates to start pressing the waste paper in the press container 16. I do. When the completion of the press is detected based on the press pressure and the elapsed time, the hydraulic cylinder 20 operates to open the presser plate 9 to the position shown by the dotted line, and then the extruding plate 10 is lowered by the cylinder 21 to the position shown by the dotted line. The waste paper extruded from the inside 16 is formed into a small block 22 and falls into the bucket 11. By repeating the above operation continuously, a block 22 formed of waste paper is produced.

During this time, the level of the processing liquid in the liquid tank 4 is checked by the level switch 14. If the liquid level falls, the processing liquid 13 is replenished from the processing liquid tank 18 via the pump 12, so that Of the processing liquid 13 always holds a fixed amount. In addition, the processing liquid 13 caused by overflow or leakage from around the block manufacturing machine is entirely passed through the tray 17 to the processing liquid tank 1.
Returned within 8.

Embodiment 2 The important thing in this type of waste paper processing apparatus is to soften the waste paper to be treated without losing the fiber quality. For this purpose, ultrasonic waves may be used instead of using a surfactant. Another embodiment shown in FIG.
And the ultrasonic oscillator 19 is arranged.
Vibration is applied to the water by the generated ultrasonic waves, so that the water easily permeates the waste paper immersed in the water. In this way, the waste paper that has been softened by the permeation of water can be stirred and loosened by the stirrer 5. Even better results can be obtained if a surfactant is used instead of water, and the surfactant is vibrated by the ultrasonic oscillator 19 and stirred by the stirrer 5.

[0012]

According to the present invention, a waste paper treating apparatus is softened by infiltrating liquid into the waste paper to form a small piece, and the small piece of waste paper is formed into a small block. Therefore, the following advantageous effects can be obtained. (1) Since the discarded paper is loosened up into small pieces, it is completely impossible to read characters and the like written on the discarded paper. (2) Since no fibers are cut, waste paper of any paper quality can be treated, and the treated waste paper can be used as recycled paper. (3) The waste paper after being processed by the processing equipment is a small block, so it is not bulky and convenient for transportation and handling. (4) Since the processing equipment is almost automated, it is easy to use.
