Field of the Invention The present invention relates to a material feeding method and apparatus for a cutting machine, and more particularly to a material feeding method for a cutting machine capable of automatically continuously feeding materials having different material diameters. And its equipment.

[0002]

2. Description of the Related Art Conventionally, as a material supplying device for supplying a work to a material conveying conveyor provided on one side of a cutting machine, for example, a structure as shown in FIG. 6 has been widely adopted.

That is, the work W is fed to the material feeding conveyor 101.
The material supply device 103 for supplying a large number of workpieces W is provided with an inclined surface 105 that rolls due to the weight of the workpieces.
A stopper 107 and a lifter 109 are provided on the carry-out side. The position indicated by the line XX in the drawing of FIG. 6 is the material parting line.

With the above structure, when the position of the stopper 107 is set according to the outer diameter of the work W and the lifter 109 is operated to push up the work W, the work W is stopped by the stopper 1.
It rolls to the upper surface of 07 and rolls along the slope to be supplied to the material feeding conveyor 101.

[0005]

By the way, in the above-described conventional material supplying apparatus, since the stopper 107 receives the total weight of the work W, rigidity is required and the material supplying apparatus 10 is used.
It is necessary to move the position of the stopper 107 in accordance with the outer diameter of the work W placed on the inclined surface 105 on the upper part 3, and it is difficult to achieve automation. The sound is even louder.

An object of the present invention is to provide a material feeding method and a device for a cutting machine capable of automatically and continuously feeding workpieces having different outer diameters.

[0007]

In order to achieve the above object, a material feeding method in a cutting machine according to a first aspect of the present invention is a material feeding device for feeding a work to a material feeding conveyor provided on one side of the cutting machine. In the material feeding method, a plurality of workpieces having different outer diameters, the positions of which are regulated by a stopper provided on the work unloading side of the material feeding device and mounted, are provided on a kicker plate adjacent to the stopper. Among multiple types of kicker devices with different pusher widths, a kicker device with a work pusher having a width corresponding to the diameter of the work can be selectively operated to transfer the work to the feeding conveyor side. It is a feature.

According to a second aspect of the present invention, there is provided a material supply device for a cutting machine, wherein a material supply conveyor is provided on one side of the cutting machine, and a material supply device for supplying a work is provided adjacent to the material supply conveyor.
