Automatic Vacuum Feed Hopper

The feed hopper shown selectively takes cards one at a time from tray 2 and drops them through slot 3 onto belt 4. Two rotatable bearings 5 and 6 are located on the sides of the tray 2. These bearings normally hold the credit cards from moving forward.

Cylinder 10 moves forward so that the end of cylinder 10 just touches the surface of the first card in the tray 2. The end of cylinder 10 has a suction cup 11 thereon. As the cylinder 10 moves forward, a switch 19 is activated by the forward movement thereby turning on a vacuum in the suction cup 11. The suction cup 11 thereby holds onto the credit card. When the piston 10 is retracted, it pulls the credit card forward. As the credit card is pulled forward, switch 19 is activated turning off the vacuum in cup 11. When the vacuum is turned off the credit card drops through the slot 3 to belt 4.

Belt 4 could be replaced by a card holding mechanism which receives and holds each card after it passes through slot 3. A cover can be placed on tray 2 to keep the cards in alignment while in the tray.
