Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for unwrapping bale waste paper, and more specifically, when unwrapping bale waste paper in which waste paper is compression molded by a baler machine and wrapped with a number line, A device for automatically cutting and removing.

[0002]

2. Description of the Related Art Conventionally, newspapers, magazines, which are raw materials for papermaking,
Used paper such as corrugated cardboard is compressed by a baler machine by hydraulic pressure to facilitate transportation and inventory, and is usually 1 × 1 × 2.
It is solidified into a rectangular shape of m, and the number wire of about 3φ is 5
It is packed with ~ 6 pieces.

[0003]

In order to use the bale waste paper thus packed as a raw material for papermaking, first, the number line must be cut and removed. Conventionally, the worker removes the numbered wire manually by using a tool such as pliers or a clipper. However, the work environment is deteriorated by dust and the work place is dangerous. For this reason, there have been proposed some devices for cutting and removing the number line of such waste bale paper, but none of them is satisfactory.

For example, as a device for cutting the number line, a blade for pushing the number line is attached to the tip of the hydraulic cylinder, the blade is pressed against the waste bale paper, and the number line is sandwiched between the waste paper and the blade to cut. However, if the packing pressure of the waste paper is weak, even if the blade is pressed with a strong force, the number line will get into the waste paper, so that the waste paper cannot be cut. Also, when the shape of waste bale paper is extremely deformed,
I can't cut the number line. In addition, there is also one that cuts the number line by pressing the cutting teeth of the shape that combines two saw-toothed cutters against the waste bale paper to operate the cutter, but again, the number line that cuts into the waste paper is also cut. I couldn't cut it.

On the other hand, as a device for removing the numbered wire after cutting, one side of the inverted U-shaped metal article is inserted between the numbered wire that has been cut and loosened and the used paper, and the metal article is rotated to rotate the numbered wire. Although there is one in which the metal wire is wound, it was not possible to reliably insert one side of the metal piece between the metal wire and the waste paper because of the degree of looseness of the metal wire.

Therefore, an object of the present invention is to provide a device for unpacking waste bale paper, which is capable of improving the above-mentioned drawbacks of the conventional device and reliably cutting and removing the numbering wire.

[0007]

In order to achieve the above-mentioned object, a baling waste paper unpacking device of the present invention is provided with a numbering line cutting device and a numbering line winding device on both sides of a conveyor which conveys the bale waste paper packed by a numbering line.
