DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for cutting a plate material or the like, which cuts a work material such as a large plate material in a vertical and horizontal direction according to a predetermined cutting pattern and divides the work material into a number of small pieces having different dimensions. .

[0002]

2. Description of the Related Art A processing machine equipped with a circular saw for vertical grinding and a circular saw for horizontal grinding and for cutting a large plate into products of various dimensions is known from Japanese Patent Publication No. 52-44040. This conventional processing machine includes a large number of vertical saw circular means arranged in the width direction of the work material, a horizontal circular saw means running in the width direction of the work material, a large number of clamper means arranged in the width direction, It is provided with a transfer means for controlling the transfer of the work material gripped by the clamper in the longitudinal direction.

In this conventional processing machine, a workpiece gripped by a clamp is traveled in the longitudinal direction to perform a vertical divisional cut, and a circular saw for horizontal grinding is traveled while the workpiece is stationary. In this way, the horizontal divisional cutting is performed. For example, the cutting processing of the wood cutting pattern shown in FIG. 17 is performed as follows.

That is, as shown in FIG. 12, a workpiece W is gripped by clampers S1 to S8 at the front side of a table (not shown), and is transported rearward (R direction in the figure) by a transport means F. At this time, vertical cutting is performed by selectively using the circular saws T1, T2, T4, and T5. As shown in FIG.
Of the three divided workpieces W1 to W3, the left and right small pieces are released at the transfer end position with the clampers S1, S7 and S8 released.

Thereafter, when the transfer means F is driven in the reverse direction, only the divided small piece W2 can be returned to the original position on the table as shown by the imaginary line in FIG. The returned small piece W2 is further cut. That is, as shown by the solid line in FIG.
Are controlled in sequence by successively moving the circular saw for horizontal grinding Y1 each time.
4, W5, and W6.

Next, the remaining divided piece W2 is pulled back forward as shown by the imaginary line in FIG. 15, and is transported backward, and cut using the vertical saw C3.
It can be divided into two small pieces W7 and W8 as shown by the solid line in FIG. Further, if the small pieces W7 and W8 are pulled back forward as shown by the imaginary line in FIG. 16 and cut by the horizontal saw Y1 while positioning the workpiece in a stepwise manner, the solid line in FIG. Can be cut out.

[0007]

As described above, in the conventional processing machine, in the processing material remaining after the cutting in the vertical direction is completed, a wood saw through which a horizontal saw can be temporarily passed. There is no problem with patterns. However, as shown in FIG. 8, when it is necessary to perform the horizontal cutting at an arbitrary position of the small piece W3 in addition to the above-described wood removal pattern, there is a problem that the processing cannot be performed.

That is, after the first vertical cutting, since the divided pieces W2 and W3 have an unprocessed portion, both pieces must be pulled back. Therefore, looking at the remaining small pieces W2 and W3, the small piece W3 has a circular saw Y1 for horizontal grinding.
Since there is a cutting line through which the vehicle cannot travel, it is impossible to perform any more desired cutting.

Conventionally, there has been no solution to such a processing problem except that the operator sets a possible tree-cutting pattern in consideration of the tree-cutting pattern. Therefore, it requires a skill and is very troublesome. However, waste cutting was unavoidable in many cases, and the waste of materials was extremely large. In addition, although the work material divided and cut is once carried out and supplied to the table again to carry out the working work, there arises a problem that the working efficiency is poor and the quality is deteriorated.

The present invention has been made in view of the above-mentioned problems of the prior art, and does not require skilled skills.
An object of the present invention is to provide a novel cutting method capable of performing divided cutting in accordance with any wood-cutting pattern and performing cutting efficiently and with high precision.

[0011]

Means for Solving the Problems To achieve the above object, a cutting method according to the present invention is as follows.

That is, the gist of the invention is a step of holding a plurality of divided workpieces cut into two or more pieces by a circular saw for vertical grinding with a clamper and returning them to a fixed position on a table. A step of pressing and fixing the plurality of divided work materials that have been pulled back at fixed positions. A step of releasing a clamper other than a part and releasing the corresponding divided material. A step of releasing the press-fixing of a part of the divided material, transferring the material, and cutting the material with a circular saw for vertical grinding and / or a circular saw for horizontal grinding. Return the clamper to the fixed position on the table,
A step of gripping some of the divided workpieces remaining on the table. A step of releasing the press-fixing of a part of the divided material, transferring the material, and cutting the material with a circular saw for vertical grinding and / or a circular saw for horizontal grinding. The cutting process is performed according to the above steps.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a method for cutting a plate or the like according to the present invention will be described in detail with reference to an embodiment. First, a number of clampers S1 to S1 set at the base position of table 1
It is gripped by S8. The configuration of the clampers S1 to S8 is as shown in FIG.
1 and an upper pawl 12, wherein the upper pawl 12 is a pneumatic cylinder 13
It is designed to move up and down. When the piston rod in the pneumatic cylinder 13 contracts, the clampers S1 to S8 close and grip the workpiece W.

The clampers S1 to S8 are provided at intervals on the mounting beam 14 disposed in the width direction, and include a driving motor 15 composed of a servomotor, a feed screw shaft 16 connected to an output shaft of the driving motor 15, A transfer means F comprising a passive nut 17 of a mounting beam 14 screwed to a feed screw shaft 16
As a result, it is controlled to move rightward in FIG. 1 (longitudinal direction of the workpiece W).

Work material W gripped by clampers S1 to S8
During transfer, four vertical circular saws T1, T2, T4, T5
, And cut into three divided pieces W1 to W3 before reaching the transfer end in FIG. The divided small pieces W1 that do not require the post-processing release the clamper S1 and are discharged outward at this end position.

The other divided pieces W2 and W3 are gripped by the clampers S2 to S8 and pulled back forward. Divided small pieces W2,
When W3 is transferred onto the table 1 and the clampers S1 to S8 reach the base position, the movement is stopped. Then, the pressing pieces P1 to P9 are operated to press and fix the divided small pieces W2 and W3 on the table 1. After fixing, all clampers S1 to S8
Are released, and the clampers S1 to S8 are retracted forward by a fixed amount from the base position. (The imaginary line position in FIG. 9) Even when the clamper is released in this manner, the pressing piece P1
Workpieces W2 and W3 do not shift due to the pressing action of P9.

Thereafter, which of the two small pieces W2 and W3 on the table 1 is to be cut first is set. The processing order is set in advance in a program, but in the wood cutting pattern of one embodiment, since one small piece W2 is processed more than the other, this piece is cut first. When a machining command is given, one of the clampers S1 to S8 at the retracted position corresponding to one of the small pieces W2 (S
2 to S6) hold the open state, and the remaining ones (S1, S6)
7, S8) performs the closing operation. The upper claw 11 of the clamper to be closed is immersed in the table 1 surface.

After the closing operation described above, each clamper S
1 to S8 move to the base position, and the opened one closes to clamp and hold the small piece W2. Then, the pressing pieces P2 to P6 corresponding to the small piece W2 retreat upward. The pressing pieces P1, P7 to P9 other than those described above keep the pressed state, and continue to fix the other small piece W3 to the table 1.

One of the divided pieces W2 is clamped to clampers S2 to S6.
This is the same as in the conventional example until the workpiece is cut into strips W7 and W8. That is, as shown by the solid line in FIG. 3, three small pieces W4 and W
5, W6 is cut out, and thereafter, the small piece W2 is vertically divided using a vertical saw circular saw T3 as shown in FIG. As shown in FIG. 5, the two divided pieces W7 and W8 are divided into twelve small pieces W9 to W12 by cutting the circular saw Y1 six times. The ends gripped by the clampers S2 to S6 are discharged at the moving end by opening.

During the above-mentioned processing, the other clampers S7 and S8 are immersed in the table 1, so that they do not interfere with the remaining divided small pieces W3.

When the machining of one of the divided small pieces W2 is completed as described above, the clamper is returned to the retracted position in front of the base position by the transfer means F, and then the clamper S7 is moved to the base position in FIG. The small piece W3 is clamped by S8. When the holding of the small piece W3 is completed, the pressing piece P
7 to P9 are retracted, and the small piece W3 is positioned by the transfer means F as shown in FIG.

Then, the circular saw for horizontal turning Y1 is sequentially moved and moved in conjunction with the positioning operation. Thereby, the divided small piece W3
Strips W13 and W14 can be cut out from the sheet. After cutting the strips W13 and W14, the clamper S7,
S8 is transferred to the moving end, and the end material is discharged at this position.
In this way, all the cutting processes in accordance with the predetermined cutting pattern are completed. After the end of the cutting process, the clamper is returned to the front base position to prepare for the supply of the next workpiece W.

According to the cutting method according to the present invention,
It is possible to adapt to various tree cutting patterns other than the above. FIG. 10 and FIG. 11 show an example.
The cutting lines indicated by the XX line and the YY line in the drawing are for edge trimming, and the dimensions are determined based on these. The scraps (hatched portions in the figure) generated by the above trimming are discarded after cutting.

[0024]

As described above, in the method of cutting a plate material or the like according to the present invention, the divided small pieces are pulled back onto the table, fixed and held, and necessary pieces are sequentially taken out from these pieces and cut. Since the processing is performed, it is possible to perform the cutting processing particularly in the horizontal direction in a divided manner, and it is possible to efficiently and highly accurately perform the cutting processing in response to the wood cutting pattern which was impossible in the past without difficulty. Demonstrates excellent effects.
