ABSTRACT:
A filter feeder for automatically feeding filters one by one to casting molds traveling in a mold transfer line includes a rotatably arranged table and a plurality of cartridges vertically arranged on the table. Each of the cartridges accommodates a plurality of filters placed one upon another. A filter discharge mechanism is provided at a lower end of each cartridge to discharge a lowermost filter of the filters accommodated in the cartridge. The filter discharge mechanism includes a pair of shutter plates pivotally mounted on the lower end of the cartridge so that the lowermost filter may be discharged from the filter discharge mechanism when the shutter plates are opened. The filter feeder is further provided with a receiving mechanism for receiving the filter discharged from the filter discharge mechanism at a first location below the cartridge. The receiving mechanism is capable of pivoting between the first location and a second location from which the filter discharged from the filter discharge mechanism is transferred towards one of the casting molds. The shutter plates are opened in association with the pivotal movement of the receiving mechanism to the first location.
