Abstract

PURPOSE:To surely discharge even fine chips and withdraw them by washing away the chips falling on a groove shaped chute by water. CONSTITUTION:When chips 5 of a work piece are let fall on a groove shaped chute 4 and intermittently removed, water stored in an overhead water tank 1 is intermittently jetted from the rear end part of the groove shaped chute 4, so as to wash away the chips 5 deposited on the chute 4. Next, the chips 5 and the water washing away the chips are collected into a catchment box 6. The water collected in the catchment box 6 is returned to the overhead water tank 1 by means of a drainage pump 7, and the chips 4 are taken out by a take-out means. By washing away the chips 5 falling on the groove shaped chute 4 by water in this way, even fine chips 5 can be surely discharged and withdrawn, and further cushioning effect is exhibited by the washing away water so as to hardly make the chip 5 in direct contact with the chute 4 and reduce abrasion of the chute 4.

However, there are the following problems in the above-mentioned conventional method of treating cutting waste by collecting the cutting waste in the groove-shaped chute and treating it.

(1) Hapun type 1) Fine cutting chips cannot be transported. 2) The long cutting waste is generally coiled, so it catches on the fins and stays as it is. Then, the cutting chips that have moved afterward may be caught and retained by the retained cutting chips. 3) Sliding surface is worn by fine cutting debris. Moreover, since metal parts such as the chute and the scrap scraping shaft are worn or deformed due to contact with the scrap, maintenance requires labor and cost.

(2) Conveyor system 1) Fine cutting dust may get into the connecting portion of the conveyor and become inoperable. 2) Especially when installed underground, if a large amount of cutting waste is transported and used together, the cutting waste will fall from the conveyor. Cutting dust is compressed between the chute and the lid, and the conveyor becomes inoperable. Repairing due to deformation, wear, etc. requires labor and cost.

The present invention has been made in order to solve the above-mentioned problems of the prior art, and the chute is not worn, fine cutting dust can be reliably discharged, and the cutting does not require labor or cost for maintenance. It is intended to provide a method for treating waste.

A method for treating cutting chips according to the present invention is a method for treating cutting chips, wherein cutting chips of a material to be cut are dropped on a groove-shaped chute and are intermittently removed.
The water stored in the elevated water tank is intermittently jetted from the rear end of the groove-shaped chute to wash away the cutting debris accumulated on the chute and the debris and cutting debris to the tip of the groove-shaped chute. We set up a water collecting basin to collect water,
The water collected in the water collecting tank is returned to the elevated water tank by a drainage pump, and the cutting waste is taken out by a taking-out means.

Another processing method for cutting chips according to the present invention is a method for processing cutting chips, in which cutting chips of a material to be cut are dropped on a grooved chute and removed intermittently. A water collecting basin is provided at the tip to collect cutting debris and water for rinsing the cutting debris. The cutting debris on the chute is washed off in a water collecting basin, and the cutting debris collected in the water collecting basin is taken out by a take-out means.

[0012]

In the method of treating cutting waste according to the present invention,
Since the cutting debris that has fallen onto the groove-shaped chute is washed away with water, even small cutting debris can be reliably discharged. Further, since the rinsed water exerts a buffering effect, the cutting debris rarely directly contacts the chute, and the chute is less worn. Furthermore, maintenance is easy because the only equipment required is water.
