[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plate material draining device for a deburring machine.

[0002]

2. Description of the Related Art In a conventional plate material draining device, a plate member is held down by the weight of an upper draining roller of a pair of upper and lower draining rollers, thereby cutting off water sprayed when removing burrs and dust.

[0003]

However, in the above-described conventional plate dewatering device in the deburring machine, the draining capability is always constant, the capability is often insufficient, and it is possible to cope with changes in the plate thickness. For this reason, there has been a problem that the draining capacity must be increased, and when the thickness of the plate material changes, the interval between the pair of upper and lower drainers must be adjusted each time.

[0004]

In view of the above-mentioned conventional problems, the present invention has a structure in which a plate material conveyed by a conveyor belt in a work carrying-in device is nipped by a pair of upper and lower draining rollers to drain the water. In the plate material draining device, a cleaner device for removing burrs remaining on the surface of the conveyor belt is provided above the conveyor belt at an upstream side of the draining roller, and an upper draining device of the pair of upper and lower draining rollers is provided. The roller is provided so as to be vertically movable and urged downward.
