Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a work transfer device in a cutting machine.

(Prior Art) Conventionally, for example, a horizontal band saw machine is known as a cutting machine for performing a cutting process on a work with a cutting tool. The work cut by the horizontal band saw machine is dropped and stored in a work storage device provided on at least one side along a path line in front of the horizontal band saw machine, for example.

When dropping a cut work into the work storage device, there are known a method of swinging a portion for supporting the weight of the work, and a method of extruding the work by a movable vise so that a fixed vise escapes.

(Problems to be solved by the invention) By the way, of the above-mentioned conventional techniques, the former method is:
It is good for relatively small diameter and light weight materials, but when processing heavy weight materials, there is a problem that the part supporting the work must be moved, which causes structural unreasonability.

Further, the latter method has a problem that the cut work can be carried out only on one side with respect to the pass line.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems by moving a vise body of a transfer vise device in a direction perpendicular to a pass line and storing a cut work in a work storage device. The object of the present invention is to provide a work transfer device.
