Abstract

In the production of electrical components where a large number of contact pins are to be fed to an assembly, there is always the possibility of the pins becoming jammed in the feeding mechanism. This is a pin feeder which reduces such disadvantageous jamming.

High Speed Pin Feeder

In the production of electrical components where a large number of contact pins are to be fed to an assembly, there is always the possibility of the pins becoming jammed in the feeding mechanism. This is a pin feeder which reduces such disadvantageous jamming.

The pins are drawn from a loading chamber into the feeding chamber of a pneumatic conveyor by a venturi action. This is created by a baffle placed over the orifice between the two chambers. Once in the feeding chamber, the pins are forced along grooves in the periphery of this chamber and then into escapement tubes leading to the assembly.

To prevent jamming of the pins as they leave the grooves in the feeding chamber, there is a gap across which the pins must traverse in free light. The escapement tubes are aligned to receive pins from respective grooves.

The gap is of just sufficient length, i. e., slightly longer than the pin length, so as to provide a region in which the pins not entering the gap have sufficient room to fall away. The gap is sufficiently small as to provide maximum guidance of the pins toward the tubes.
