Abstract

PROBLEM TO BE SOLVED: To accurately cut a work after truing up the side edge to a vice reference line over the total length of the work even if the work is in heavy weight. SOLUTION: The work W is carried on a material sending line to a cutting position CL of a cutter 1 having a cutting tool 7 for cutting the work W. When cutting the work W by truing up the side edge to a work width reference line DL of the material sending line, the tip side of the work W is trued up in the side edge to the work width reference line DL by a vice device 13 of the cutter 1 arranged in the vicinity of the cutting position CL. The rear side of the work W is trued up in the side edge to the work width reference line DL by a work side edge truing-up device 31 in a position passing through by a proper interval to the rear side by the cutting position CL. Even if the work W is carried on the material sending line in a state of obliquely including relative to the work width reference line DL, the work W is surely positioned on the work width reference line DL over the total length, and can be accurately cut.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cutting machine, such as a band saw machine or a circular saw machine, which performs a cutting process on a portion to be cut of the work with a cutting tool such as a band saw blade or a circular saw blade. The present invention relates to a work cutting method and a work processing system for cutting a work by shifting the work to a work width reference line in a material feeding line to be conveyed.

[0002]

2. Description of the Related Art Briefly, for example, a band sawing machine as a general cutting machine has a box-shaped base.
A saw blade housing having a movable endless band saw blade is provided on the base so as to be able to move up and down. Also,
The saw blade housing is provided so as to be horizontally pivotable about a central axis erected on the base. Accordingly, the cutting position of the band saw blade is freely changed from a position where the band saw blade is cut in a direction orthogonal to the material feeding direction to a position where the band is turned at a desired angle.

Further, a main body vise device is provided at a position behind the cutting position and close to the cutting position as viewed from the material feeding direction on the base, and the main body vice device is provided with a clamp cylinder. A pair of main body vice jaws for clamping a work by operation are provided.

[0004] A material supply conveyor is provided on the rear side of the main body vise apparatus in the material feeding direction, which constitutes a material feeding line for transferring a work.

After the portion to be cut of the work is conveyed and positioned at the cutting position, the work is clamped by the pair of main body vice jaws. Then, while the band saw blade is running, the saw blade housing is moved down, so that the cut portion of the workpiece is cut.

[0006]

On the other hand, in a conventional material feeding line of a cutting machine, if a workpiece is loaded with an inclination with respect to a vice reference line and the workpiece becomes heavier, the workpiece may be moved to the main body vise apparatus. However, since the work cannot be brought close to the vise reference line even if the work is clamped, the work is cut while being bent, resulting in a defective product. Or,
There is a problem that the cutting processing system is stopped due to a feeding failure.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and an object of the present invention is to cut a work even if the work is heavy, by shifting the work to a vise reference line over the entire length of the work. It is an object of the present invention to provide a work cutting method and a work processing system capable of accurately performing the work.

And positioning the cut portion of the work at a cutting position of the cutting machine, and moving the leading end side of the work to the work width reference line by a vice device of a cutting machine provided near the cutting position, thereby performing the cutting. A cutting process is performed after the rear side of the work is shifted to the work width reference line at a position behind the position at an appropriate distance from the work.

Therefore, even if the work is conveyed on the material feeding line in a state of being inclined with respect to the work width reference line, the leading end side of the work is shifted to the work width reference line by the vise device, and The rear side is also clamped by being moved to the work width reference line by the work width adjustment device, so that the work is reliably positioned on the work width reference line over the entire length.

[0010] According to a second aspect of the present invention, there is provided a workpiece cutting and processing system provided with a material feed line for transporting a work to a cutting position of a cutting machine provided with a cutting tool for cutting the work, and a work width reference in the material feed line. In a work cutting processing system for performing a cutting process after shifting the workpiece to a line, a vise apparatus for clamping the tip side of the workpiece positioned at a cutting position of the cutting machine to the workpiece width reference line. Is provided in the cutting machine, a movable vise for moving the rear side of the work to the work width reference line at a position appropriately spaced behind the cutting position, and the work width reference for abutting the work. A work width shifting device including a fixed vise positioned on a line is provided.

Therefore, the operation is the same as that of the first aspect, and even if the work is conveyed on the material feeding line in a state of being inclined with respect to the work width reference line, the tip end side of the work is controlled by the vise device. The work is aligned to the work width reference line, and the rear side of the work is pressed and clamped by the fixed vise located on the work width reference line by the movable vise of the work width adjustment device. It is located on the width reference line.

According to a third aspect of the present invention, in the system for cutting and processing a work according to the second aspect, the work width shifter is provided on at least one of a fixed vise and a movable vise, and a side surface of the work. And a vertical roller capable of abutting the roller.

Accordingly, the rear side of the work to be widened by the work width adjusting device is clamped via the vertical roller provided on at least one of the fixed vice and the movable vise, so that the work is clamped by the work width adjusting device. However, the workpiece is easily moved in the material feeding direction and positioned at the cutting position.
