[0002]

[Prior art]

 In the industrial world, a chip is installed in a tank of a chip processing device for processing chips generated by metal processing by a machine tool, etc., and the chip discharged from the machine tool into the tank is collected and placed outside the tank. In the chip conveyor device for discharging, a scraper that is attached to the endless rotating belt of the chip conveyor device at regular intervals and moves in the tank in the chip discharging direction as the endless rotating band moves in the chip discharging direction, A chip conveyor device capable of transporting the chips settled in the tank without remaining in the tank and moving the scraper in the tank in the direction opposite to the chip discharging direction is desired. ing. FIGS. 4, 5, and 6 are schematic explanatory diagrams of a typical processing device for cutting chips contained in coolant discharged from a machine tool that performs cutting using a coolant, which is conventionally provided. It is. Chips contained in the coolant discharged from the machine tool flow into the dirty tank 12 of the chip processing device together with the coolant. In the dirty tank 12, an L-shaped scraper 32 is attached to the endless chain belt 16 at regular intervals, and the endless chain belt 16 driven by the motor 19 with a speed reducer moves the endless chain belt 16 to remove chips on the entire surface of the scraper 32. The chip conveyor device 15 for transporting the chips is provided, and the chips settled in the dirty tank 12 are transferred by the chip conveyor device 15 along the inclined rising plate 13 on the bottom surface 11 of the dirty tank 12 into the receiving box 20 outside the dirty tank 12. It is scraped. The lower end 25 of the scraper 32 for transporting chips in the chip conveyor device 15 is provided to prevent occurrence of abnormalities such as overload of the motor 19 with a speed reducer due to interference with the bottom surface 11 of the dirty tank 12. Alternatively, a gap 33 is provided between the lower end 25 of the scraper 32 and the bottom surface 11 of the dirty tank 12 so that the scraper 11 can be moved in the direction opposite to the chip discharge direction. Fine chips that cannot be settled in the dirty tank 12 are filtered by a filter device 29 such as a paper filter, flow into a clean tank 30, and fed to a machine tool by a coolant pump 31.
