Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a strip trim processing device for compressing trim scrap produced in a trimming process for continuously cutting both widthwise ends of a metal strip.

[0002]

2. Description of the Related Art Trim scraps generated during continuous trimming of a running strip are compressed and processed into block-shaped trim scraps (hereinafter referred to as "veils").
Such an apparatus has been disclosed by the trim waste processing apparatus disclosed in Japanese Patent Laid-Open No. 62-123396. The device disclosed in the above publication, as shown in FIG. 4, FIG. 5 and FIG.
Trim waste 4 generated by cutting both ends of the strip 1 by the side trimmer 2 is accumulated in the trim waste accumulating chamber 12 by the hopper 3, and first, by the first pressurizing head 13 operated by the cylinder 20, the line direction is set. To the chamber 15 and then compressed by the second pressure head 14 operated by the cylinder 22 from above to the block 11 and then the third pressure head 5 operated by the cylinder 6. Is pressed and compressed in the width direction of the strip 1 and further compressed and compressed in the line direction by the fourth pressing head 7 operated by the cylinder 8 to form a bale.

[0003]

The conventional apparatus shown in FIGS. 4 to 6 requires four steps of pressurizing and compressing, which increases the processing time and complicates the structure of the apparatus. there were. Moreover, since a large amount of trim waste is supplied in a short time on the high-speed running line of the strip,
There is a problem that the processing cannot be done in time, and the manufacturing cost of the device becomes high. The present invention is intended to solve the above-mentioned conventional problems by shortening the processing time of trim scraps and making it possible to cope with high-speed running of the strip, and by providing an inexpensive device.

[0004]

Therefore, according to the present invention, trim scraps produced by cutting both edge portions of a traveling strip by side trimmers are accumulated in a pressurizing chamber in a casing by a hopper, and the added waste is removed. In a strip trim treatment device that pressurizes in a pressure chamber and compresses into blocks, a first pressure chamber and a first pressure device that press the trim waste in a line direction in a pressure chamber of the casing, A second pressure chamber and a second pressure device which apply pressure in the width direction of the strip, and a third pressure chamber which applies pressure in the vertical direction.
It is provided with a pressurizing chamber, a third pressurizing device, and a bale discharging device, which is a means for solving the problem.

[0005]

[Function] Trim scraps cut from the running strip by the side trimmer are accumulated in the first pressure chamber through the hopper,
The first pressurizing device pressurizes in the line direction to compress it into the second pressurizing chamber, and the trim scraps pressurize in the width direction of the strip by the second pressurizing device to compress it into the third pressurizing chamber. The waste is pressed in the vertical direction by the third pressurizing device to form a bale of a predetermined size. Then, the bale is discharged to the outside of the third pressurizing chamber by the discharging device and is conveyed to a predetermined place by the conveying device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the accompanying drawings. FIG. 1 to FIG. 3 show an embodiment of the present invention, FIG. 1 is a side sectional view of a trim waste processing apparatus, and FIG. A sectional view and FIG. 3 are sectional views taken along line BB of FIG. 1 is a strip plate,
Reference numeral 2 is a side trimmer, and 4 is a trim scrap, which are the same as those shown in FIGS. 4 to 6. 1 to 3, reference numeral 31 denotes a casing, and inside thereof, a first pressure chamber 31a is formed by a first pressure head 33, a second pressure head 37, and a third pressure head 39. A blade 34 and a partition plate 36 are mounted on the first pressurizing head 33, and the head 33 is moved in the line direction by the first pressurizing cylinder 35. The second pressure head 37 is moved by the second pressure cylinder 38 in the strip plate width direction. The third pressure head 39 is configured to move in the vertical direction by the third pressure cylinder 40.

When the first pressurizing head 33 moves as shown by the chain double-dashed line in FIG. 2, a second pressurizing chamber 31b is formed, and the second pressurizing head 37 further moves as shown by the chain double-dashed line in FIG. When moved to, the third pressure chamber 39 is formed by the third pressure head 39, the gate 41, and the discharge head 44. The gate 41 is moved by the air cylinder 42 in the strip width direction, and the discharge head 44 is moved by the air cylinder 45 in the line direction. Reference numeral 46 denotes a transfer device, which is connected to the third pressurizing chamber 31c. A hopper 48 is mounted on the upper part of the casing 31.

The operation of the embodiment configured as described above will now be described. The trim scrap 4 obtained by cutting both ends of the running strip 1 by the side trimmer 2 is passed through the hopper 48 to the first pressurizing chamber 31a. Accumulate inside. When the trim waste 4 reaches a predetermined weight, the first pressurizing head 33 is moved by the first pressurizing cylinder 35, and the trim waste 4 is moved to the second pressurizing chamber 31.
Press b. At this time, the trim waste 4 protruding upward from the first pressure chamber 31a is cut by the blades 32 and 34 and remains on the upper surface of the partition plate 36 that has moved together with the first pressure head 33, and further the upper surface of the partition plate 36. The trim scraps 4 that are continuously cut are accumulated one after another. Next, the first pressurizing head 33 is fixed as it is, and the second pressurizing head 37 is moved by the second pressurizing cylinder 38, so that the second pressurizing chamber 31b is pressurized and compressed by the first pressurizing head 33. The trim waste 4 is pressed into the third pressurizing chamber 31c and compressed. Next, the third pressurizing head 39 is lowered by the third pressurizing cylinder 40 to pressurize and compress the trim waste 4 to form the bale 4a having a predetermined size, and the air cylinder 42 opens the gate 41, By moving the discharge head 44 with the air cylinder 45, the bail 4a is pressed and moved onto the transfer device 46, and the transfer device is transferred to the next step.
Next, when the first pressure head 33, the second pressure head 37, the third pressure head 39, the gate 41, the discharge head 44, etc. are returned to their original positions, the trim scraps 4 accumulated on the partition plate 36 are removed.
Falls into the first pressure chamber 31a. The third pressure head 39 may be configured to apply pressure from below to above.

[0009]

As described in detail above, according to the present invention, trim chips that are continuously cut are accumulated in the first pressurizing chamber via the hopper and are pressurized in the line direction by the first pressurizing device. Are compressed in the second pressurizing chamber, the trim scraps are compressed in the width direction of the strip by the second pressurizing device and compressed in the third pressurizing chamber, and the trim scraps are vertically moved by the third pressurizing device. By pressurizing and molding into a bale of a predetermined size, it becomes possible to reduce the pressurizing and compressing step to three stages and shorten the processing time, and the apparatus can be simplified. Therefore, it is possible to obtain a high production amount by coping with the speeding up of the line, and it is possible to reduce the device manufacturing cost.
