Feed mechanisms
Abstract:
A feed mechanism suitable for a coining press comprising two or more feed members which are adapted to reciprocate along respective longitudinal axes and which reciprocate in synchronism so that each in turn feeds a workpiece from an associated feed station to a work station which is common to all of the feed members. Preferably, each feed member is adapted so as to feed workpieces one at a time from the feed station to the work station and back to a separate unloading station associated with the feed member, the feed station and unloading station for each feed member lying on the same side of the work station. Further each feed member is preferably a plate with a hole therethrough to receive a workpiece in the form of a flat blank, and the blank is worked on through the hole at the work station and is withdrawn in the hole to the unloading station where it is removed by a blast of air. Most simply, the workpiece is blown downwards and falls from the hole, a shutter being provided below the feed plate at the work station which opens in synchronism with the movement of the feed plate to allow the workpieces to be so removed.
