There is a problem in that the width of the material feeding device becomes wider and the space of the material feeding device is not used effectively.

This is because normally, it is rather rare to use only fixed length workpieces, and it is becoming more common to use short workpieces such as end length materials and workpiece materials to take out products.

The purpose of the present invention is to improve the above-mentioned problems by making it possible to place end lengths of workpieces and unfinished materials in the same line in the longitudinal direction of the material feeding device, thereby making effective use of space, and to provide a wide An object of the present invention is to provide a material feeding device for a cutting machine that can load many workpieces and feeding the material, and a material feeding management method using this material feeding device.

There are multiple feeding devices, and each feeding device is driven independently by each drive device, so the end posts of the workpiece and the materials in progress can be placed on each feeding device in a line in the longitudinal direction of the feeding device, and then fed. The material is fed to the equipment.

When the drive devices of each material feeding device are driven in synchronization, a work such as a fixed length material placed across each material feeding device is also fed to the material feeding device.
