Description

  The present invention relates to an improvement of a traveling circular saw machine that can efficiently perform a longitudinal cutting process (lip cut) of a large plate material and a transverse cutting process (cross cut) of a small material.

  A traveling circular saw with a plurality of ruler plates arranged for one saw traveling slit, each of which is controlled and moved to efficiently perform lip cutting of large plates and cross cutting of small materials. The board is well known by the invention of Japanese Patent Laid-Open No. 4-125102 relating to the applicant's previous proposal.

  As shown in FIG. 8, the traveling circular saw machine according to the present invention has a table area for receiving a large plate material and performing a lip cut, and a table area for receiving a split material and performing a cross cut independently. It is. For this reason, as shown in the figure, a saw travel stroke, that is, a table width, which is the sum of the length Lh of the largest large plate material Wa and the width Wh of the largest piece material Wb, is required. It was pointed out that the cost would increase. In addition, because of the structural members that divide the two table areas, there is a problem in that work materials cannot be freely transferred on the table and workability is poor.

In addition, the ruler means Ma and Mb of the traveling circular saw machine according to the previous proposal only contact the workpieces Wa and Wb. For this reason, manual work is required to transfer the processed material to the back side of the table. Further, even when the workpiece is transferred to the front side and used for cutting, there is a drawback in that high-precision positioning cannot be performed due to deviation.

The configuration of the traveling circular saw machine according to one embodiment is as described above, and the workpiece is cut as follows.

First, when performing a longitudinal cutting process (lip cut) of a large plate material, the processing material W is placed on the table 4 so that the long side is parallel to the saw travel slit 19. And the edge part of this workpiece W is clamped with both the clamp claws 48 and 58 in the 1st and 2nd ruler means Ea and Eb, and it transfers to the position of FIG. Thereafter, the first and second control driving means Da and Db are driven in an interlocked manner, and the workpiece W is sequentially moved to the planned cutting position indicated by the one-dot chain line in FIG. Make a cutting process.

Here, since the table area corresponding to the first ruler means Ea and the table area corresponding to the second ruler means Eb are formed in series, the entire area of the table is shared to receive the large work material W. be able to. For this reason, an effective cutting process can be performed.

The processed materials W1 and W2 after the lip cut are temporarily stocked on the front side of the table 4.
