Description

  The present invention relates to a method and apparatus for cutting a processed material for processing four surfaces of a processed material (hereinafter simply referred to as a processed material) such as a column material, a beam material, and a girder material, in particular, the upper and lower sides of the processed material with distortion, The present invention relates to a workpiece conveying method and apparatus capable of cutting a surface including a distorted portion of the left and right surfaces and taking out a workpiece having a specified dimension with a maximum common divisor with good yield.

  In general, a square member such as a columnar material or a beam member is dried before being processed and strained as much as possible, and then processed into a specified size using a two-sided or four-sided grid. However, when moisture or the like is removed during the drying of the wood, width warping, bending, twisting, and the like as shown in FIG. 6 occur, so that a portion that cannot be finished to a specified size appears. Particularly for “twisting”, in the conventional four-sided board machine, the tip of the material is pressed by the feed roller when the workpiece is put in, so the entire reference surface (lower surface) of the tip hits the table or lower roller of the board machine, At the rear end, the reference surface (lower surface) is cut in a state where it is raised above the cutting allowance of the lower arm, so that there is a problem that the cutting residue is left and the material thickness becomes thinner than the specified dimension.

  As described above, as a conventional planer board that properly removes distortion before processing of a workpiece and finishes it to a specified size, for example, a slide beam is placed in the transfer direction of the workpiece on the upper side of the casing. A movable body that extends horizontally along the sland beam is movably disposed along the sland beam. The workpiece is moved from the width direction intersecting the transfer direction by the clamp mechanism. The workpiece, which is gripped and positioned in a state of being cut larger than the maximum bending amount of the workpiece with respect to the highest position of the saddle drum, is gripped by the clamp mechanism, and the movable body is used as a slide beam. A non-uniformity cutting board has been proposed in which the lower surface of the workpiece is cut by a required amount by removing the unevenness by moving along the surface (Patent Document 1).

  In addition, as another conventional shading machine, a woodworking machine is equipped with an endless (endless) caterpillar drive device for feeding materials on the front and rear tables of the main shaft, and above this is a support head for several material pressing rollers. It is supported so that it can be adjusted up and down by supporting screws provided at the front and rear of the main body head, and a vertical axis rod for side correction of the material is installed at the upper right side of the rear table, and a control panel is installed at the rear of the main body head, There has been proposed a caterpillar lower feed automatic right angle turret board with an operation panel switch box installed at the front (Patent Document 2).

  When processing a workpiece with distortion on a two-sided or four-sided grid, if it is processed with a cylinder while being pressed by a pressing means such as a pressing roller, it will be processed with distortion after processing. . An apparatus that grips with a clamp mechanism in a state where distortion occurs and performs processing while being transferred in that state is complicated and the apparatus becomes complicated and the operation is unavoidable. In addition, since the deformation of the workpieces is not uniform and often varies, it is difficult to cut all the workpieces to the specified dimensions.

  The present invention has been made in order to address the above-described problems, and removes distortions such as “unevenness” and “twist” of a workpiece appropriately with a relatively simple mechanism, and defines a workpiece after processing. The surface including the strained parts of the upper and lower surfaces and the left and right surfaces of the workpiece that is distorted is retained while maintaining the dimensions of the workpiece, and the workpiece of the specified dimension is taken out with the greatest common divisor with good yield, and there is no "cutting residue" It aims at providing the cutting method and apparatus of a workpiece.

  According to the method and apparatus for cutting a workpiece according to the present invention as the above means, only the surface portion of the workpiece having warpage, bending, or twisting, which has caused warping, bending, twisting, or the like is scraped off. It is possible to take out square bars and beam materials with specified dimensions without cutting residue. In addition, there is almost no problem of cutting with a lower cutting allowance due to the lower barrel, which has been a problem in the past, or lack of specified dimensions due to the remaining cutting. Furthermore, according to the method and apparatus for cutting a workpiece according to the present invention, even if the workpiece has a twist or the like, a workpiece having a specified dimension is taken out with a maximum common divisor with a good yield, and a “cutting residue” is obtained. It is possible to take out a processed material that is not easily generated.
