Description

DETAILED DESCRIPTION OF THE INVENTION The present invention mainly relates to a wire clamping device used in a removing device for removing wires that bind compressed waste paper or the like.

After waste paper such as newspapers and magazines is collected, it is recycled by waste paper companies.
It is formed of compressed waste paper 10 as shown in FIG. This compressed waste paper is transported, crushed in a crusher at a paper mill, melted, and recycled. When using the crusher, it is necessary to remove the wire from the compressed waste paper.

As a device for performing this work, a removal device 14 shown in FIG.
has been devised. This device 14 detects and stops compressed waste paper 10 transported by a conveyor 16 with an optical sensor 18, and cuts the wire 12 with a cutting device 20 at approximately the center of one side of the compressed waste paper. ), then near the corners 22 at both ends of this side, the wire 12 is loosened by the loosening device 24.
Then, hold it between the two sides and move it away from the corner 22 (see Figure C), and then take it off from the opposite side with the hook 26 (see Figure C). The reason why the wire 12 is separated from the corner 22 in this operation is because the wire 12 is still biting into the corner 22 and cannot be pulled out with the hook 26 if the wire 12 is simply cut. Note that the contact between the corner 28 on the side of the hook 26 and the wire 12 does not hinder the work in any way.

The present invention mainly relates to a clamping device used for clamping the wire 12 in the loosening device 24 of the removing device 14.

Since the wire 12 that binds the compressed waste paper 10 is not necessarily in a fixed position, this clamping device is
It must be able to securely hold the wire 12 regardless of the situation.

The present invention is aimed at answering these demands, and has two clamping pieces in which a plurality of rod-shaped bodies are protruded in a line at regular intervals, and these clamping pieces are put together to form a structure in which both clamping pieces are assembled. Compressed waste paper, etc. characterized by having a drive unit that moves one clamping piece relative to the other clamping piece from a state in which the rod-shaped bodies of the pieces are put together and clamps a wire between the rod-shaped bodies of both clamping pieces. This is a wire clamping device.

Hereinafter, an example in which the present invention is applied to the loosening device 24 will be described with reference to FIGS. 4 to 7.

In the loosening device 24, 30.30 is a column mounted on a rail 32 running parallel to the side of the conveyor 16. A fixed column 34 is fixed on the rail 32 on the side of this column 30, and both columns 30.30 are moved left and right on the rail 32 as one by an air cylinder 36.36 attached to this fixed column 34. .

At the bottom of the column 30.30 there is a support rod 38. extending forward.
38 is provided protrudingly, and the clamping piece 42 of 1 of the clamping device 40 is attached here.
The lower part of the is slidably connected. Also, this clamping piece 42
is the column 30 at the upper and lower support points 44 and 46.
．． 30, and the operation of these air cylinders 48.50 allows the entire clamping device 40 to move back and forth and tilt.

The clamping device 40 includes a clamping piece 42, a clamping piece 52, and a driving section 54 made of an air cylinder or the like. The entire clamping piece 42 extends vertically, is attached to the column 30.30 as described above, and has six rod-shaped bodies 56.30 in front. ... are protruding in a row at regular intervals. The clamping pieces 52 are almost the same as the clamping pieces 42 and the six rod-shaped bodies 62 of the gate structure. They protrude in a row with the same spacing as... The drive part 54 is the clamping piece 4
2, and is combined with the clamping piece 52, and the clamping piece 5
2 is moved up and down along the clamping piece 42. At this time, when the clamping piece 52 is raised, the rod-shaped body 56. ..., 62.・
Five of them come together, and in the lowered state, all six come together. Incidentally, by raising the clamping piece 52, each rod-shaped body 56..., 62. When put together, the tip will have a sharp shape.

Limit switches 64 and 66 projecting forward are provided near the support points 44 and 46 of the clamping piece 42, respectively, and the upper limit switch 64 is connected to the upper air cylinder 48,
The lower limit switch 66 is connected to the lower air cylinder 50.
The clamping device id 40 is coupled to the rod-shaped body 56.・・・
・,62. ... is detected to be close enough to slightly enter the compressed waste paper 10, and the air cylinders 48 and 50 are stopped.

The loosening device 24 has the above-described structure, and is operated by a control section (not shown) as follows.

Firstly, the column 30.30 is the rod-shaped body 56 of the clamping device 40.
．． ..., 62. ... is positioned so that it is slightly closer to the corner 22 area of the compressed waste paper 10, and after the wire 12 is cut, the air cylinders 48, 50 are activated, the clamping device 1i40 begins to move forward, and the limit switch is activated. 64.66
Stops when activated. At this time, the clamping piece 52 is in a raised state, and the clamping pieces 42, 52 are set parallel to the side surface of the compressed waste paper 10 due to the limit switches 64, 66, and the rod-shaped body 56. ..., 62. . . . are all in a state in which they have slightly entered the side surface of the compressed waste paper 10. Next, actuate the drive unit 54 to lower the clamping piece 52 and move the wire 12 to the rod-shaped body 56. ... and stick state 62. Sandwiched between...
While retracting the entire clamping device 40 using the air cylinders 48 and 50, the air 7 cylinders 36 and 36 are operated to move the column 30° 30 along the rail 32 in the direction away from the cutting device JR20, and the wire 12 is removed from the compressed waste paper 10. Separate from corner 22. After completing the work of loosening the wire 12, the clamping device 40
raises the clamping piece 52 to release the wire 12, and the column 30.
30 moves and returns to its original position.

As is clear from the above-mentioned operation, this gripping device [η40] is activated by the movement of the rod-shaped B56 by the advancement of the clamping device 40, no matter where the chute 12 is located. ..., 62°... 1131, and the lowering of the clamping piece 52 ensures that 1 is held in the shape body 56.
..., 62. ...is held in between.

Therefore, according to the clamping device of the present invention, even if the wire is deviated from its normal position or the standard of the position where the wire is tied is different, the wire can be held as is without making any adjustments to the device. Can be held.

Therefore, the invention is not limited to the above-mentioned wire loosening device for compressed waste paper.
It can be widely used for gripping 63 binding wires, strings, etc. of pulp, cotton, etc.
