DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a crusher or a disintegrator (hereinafter referred to as a crusher or a disintegrator) for automatically separating sheet-like materials such as paper, pulp and film into a desired thickness or number of sheets. (Pulper), a disintegrator and the like.

[0002]

2. Description of the Related Art A process of unpacking a pulp sheet bale at a papermaking or viscose fiber (rayon, cellophane, etc.) plant and putting it into a disintegrator or a dissolving machine.
When a certain stack of pulp sheets is put in at once, undisintegrated sheets remain, causing various troubles in the subsequent steps. Therefore, it is necessary for two workers to stand at the loading port on both sides of the conveyor and to sort and feed both sides of the sheet with a certain thickness or one sheet at a time, which is a bottleneck in labor saving.

[0003]

On the other hand, a pulp sheet is made into a very thick sheet by a pulp sheet making machine at a pulp mill, cut to a certain size by an on-machine, and weighed in a range of approximately 200 to 300 kg by a Revoy. Stack up,
After that, via a conveyor line, a pressing process of compressing the volume to almost half by a hydraulic press, a baling process of covering the bottom and top with a bale, and further packing while strongly tightening the length and width in a cross or cross-shaped Through the wiring process, it is completed and shipped as packing pulp.

[0004] When pulp compressed and packed through the above-described steps is stacked one by one with a cutter, the thickness of the pulp is as large as 1000 g / m ² when the sheets destined for one sheet are stacked in a Rayboy of a paper machine. Is irregular, its ends are not always aligned in a line, it may slip back and forth due to the recoil at the time of collision with the stopper, and several sheets may be manually pulled in order to obtain a constant weight when weighing. The pulp waste paper when the sheet runs out is properly folded and inserted.

[0005] The pulp sheet that has slipped back and forth, left and right, or has been folded in an overlapping manner is covered with a bale up and down and strongly tightened with a thick iron wire, and then tied with a motor-driven wire clamp machine to further tighten the pulp bale. ,
The outer shape of the packaging pulp is not a rectangular parallelepiped but a rounded shape, and each ridge is in a state where the wire is tightened in a curved shape by the wire by a strong tightening operation of the wire and bites into the inside.

[0006] Therefore, even if the bale is removed by cutting the pulp wire, the individual pulp sheets are in a state of biting each other. However, even if it can be divided into large chunks, each chunk has a block-like shape of the pulp sheet that has penetrated each other, causing unpulverized or uneven pulverization, damage to some fibers, and the like.

On the other hand, in order to automate the division of the pulp bale, it is conceivable to use a separator knife having a sharp cutting edge to push the bale from both sides or the rear of the bale with a chain drive by a motor or a hydraulic cylinder.
As described above, the pulp sheets are not aligned in a fixed posture, and are often bitten into each other to form blocks, which makes it difficult to divide easily.

[0008]

DISCLOSURE OF THE INVENTION The present invention overcomes the above technical difficulties, and even if the pulp bale has a pulp sheet in which one pulp sheet is densely packed in one block, the pulp bale can have any thickness or number of sheets.
