Hydraulic Operated Vacuum Card Feed

This card feed apparatus serially moves card 1 from hopper 2 to work station 3, i.e., card punch or card reader, and to stacker 4.

The device comprises stationary rail 5 spanning three card stations 2, 3 and 4, and parallel-spaced shorter transport rail 6 movable in the direction of its extension. Rail 6 has a length spanning across two card stations. Each of the adjacent edges, at the front face of rails 5 and 6, is grooved to form, respectively, spaced seats 7 and 8 for lateral edge portions of the cards.

Seat 8 of rail 6 is perforated or slotted at longitudinally spaced points to provide spaced apertures 9 in communication with two chambers 10 and 11 disposed within rail 6 and separated by internal partition 12. Chambers 10 and 11 are, respectively, provided with inlets 13 and 14 for controlled communication with a source of vacuum.

Rail 6 is actuated by a hydraulic piston unit 15 for movement in one direction. Rail 6 is actuated by spring 16 for return of rail 6 to its start position.

In operation, section 17 of rail 6 in its start position, is disposed in front of hopper 2. Vacuum is applied in chamber 10 to grip and hold the top edge of card 1 in a corresponding portion of seat 8. Unit 15 is controllably pressurized to advance rail 6 which carries card 1 to work station 3 and also positions transport rail section 18 in front of feed hopper 2. Vacuum is applied to chamber 11 to grip and hold the top edge of second card la...
