ABSTRACT:
A vibratory feeder device has a forward moving mechanism and recirculating, or return, mechanism side by side and separately and independently controllable. The forward feeding mechanism has a feeder track that includes an angularly sloping surface down which devices to be fed, such as transistor chips, slide under the influence of gravity into the return chute unless caught by the terminals of the fed devices. The angularly sloping surface has a groove in the feed direction in which the terminals become engaged. If the device's terminals are engaged by the groove so that they are in the proper attitude, the devices are fed along under the vibratory feed forces. If not, they are brushed off onto the angularly sloping surface by a blade or fall through a hole adjacent a deflector. In either case the rejected devices are returned to the supply hopper. Devices that are properly oriented are moved with their terminals out of the groove and onto the ledge of a lower rail that guides them into a feed pathway formed with a second or upper rail. Adjacent the entry to the feed pathway there is a further hole through which rectangular devices, oriented vertically rather than horizontally, fall. The further hole also enables the row, or file, of properly oriented devices to buckle and spill into the return chute when the oriented devices at the end of the feed pathway are not being moved away fast enough.
