Abstract: A collapsible chip conveyer includes a conveying member having a forwarding portion and a return portion. The conveying member receives chips discharged from a machining tool at a receiving position set on the forwarding portion, conveys the chips to a discharge position, which is located on the forward portion and spaced from the receiving position by a predetermined distance, and discharges the chips from the discharge position. The conveying member has a guide rail, a frame, and a hinge mechanism. Also, the conveying member includes a plurality of separation portions, each of which includes a part of the guide rail and a part of the frame. The hinge mechanism has a rotation axis, which is located between the forwarding portion and the return portion, and couples the separation portions such that the separation portions pivots about the rotation axis between a collapsed position and an opened position.

Abstract: A chip conveyor (K) which receives chips delivered from a machine tool (MC) in a receiving area (R1) transfers chips to a delivery position a specified distance apart from the receiving area, and is provided with an endless carrier (18) rotatably in a specified direction to deliver chips at the delivery position, characterized in that a passage ranging from the receiving area to the delivery position is used as a go route (R2) for the carrier, a passage ranging from the delivery position back to the receiving position is used as a return route (R3) for the carrier, and a separating device (25) which separates chips from the carrier by allowing liquid to act on the chips adhering to the carrier which passes the delivery position so that their adhesiveness is reduced or eliminated is installed in the return route, whereby the residual chips can be removed efficiently from the carrier so as to increase the durability of the carrier and a drive mechanism.

Abstract: An apparatus electrochemically removes fine metal particles from an oil in water emulsion. The apparatus has a container for accommodating the emulsion. A supply port supplies the emulsion to the container. A plurality of cathode plates and anode plates are located in the container to face each other. The water in the emulsion is electrolyzed when a predetermined direct voltage is applied between the plates. The fine metal particles float with hydrogen generated by the electrolysis. Al(OH)3 attaches to H2 bubbles. A discharge port is located in a lower part of the container for discharging the emulsion from which the fine metal particles, sludge, oil and greese have been removed.

Abstract: A conveyor is provided with a casing (2), an endless conveyor belt (9) located in the casing (2) to circulate. The conveyor belt (9) has a pair of roller chains (11) attached to the peripheral edges on each side of the belt. Each roller chain (11) has a plurality of rollers (13). The casing (2) is provided with a lower split body (14) and an upper split body (15) fixed on the lower split body (14). The lower split body (14) has a pair of side frame members (17 and 18) formed by press molding. The side frames (17 and 18) each have a lower supporting portion (20) and an upper supporting portion (22), for supporting the rollers (13). That is, some portions of the casing (2) serve as the roller supporting portions (20,22). This reduces the number of steps in the manufacture of conveyors, facilitates manufacture of the same, and reduces the manufacturers' cost.

Abstract: A chip conveyor includes an endless carrier that circulates in a predetermined direction such that chips discharged by machine tools are collected at a collecting position, are carried to a discharging position, which is spaced from the collecting position by a predetermined distance, and are discharged at the discharging position. The carrier follows an upper path from the collecting position to the discharging position and returns through a lower path from the discharging position to the collecting position. A reservoir tank is provided to correspond to the lower path of the carrier. The carrier passes through the reservoir tank, and chips attached to the carrier are separated from the carrier in a liquid in the reservoir tank.

Abstract: A chip transporting conveyor includes a conveyor frame and an endless conveyor belt mounted on the conveyor frame and movable in circulatory motion for transporting and discharging chips at a terminal end of a conveyor zone. The endless conveyor belt having at least one magnet housing extending transversely of the endless conveyor belt. A permanent magnet body is accommodated in the magnet housing and movable therein between an attractive position in which the permanent magnet body is located adjacent to an inner wall surface of the magnet housing for attracting the chips to an attracting surface of the magnet housing while the chips are being transported and an unattractive position in which the permanent magnet body is located remotely from the inner wall surface for discharging the chips off the magnet housing when the latter is inverted around the terminal end.
