Abstract

A concept is disclosed which provides a normal force directed on the forward portion of the magnetic cards in a card feeder near the card gate and directed in a direction to iron the magnetic cards flat to the gate floor. Also disclosed is a concept for removing the normal force and moving the tray or floor of the card feeder to allow the insertion of magnetic cards into position for subsequent feeding.

NORMAL FORCE SYSTEM FOR MAGNETIC CARD FEEDER (Cont'd)

A concept is disclosed which provides a normal force directed on the forward portion of the magnetic cards in a card feeder near the card gate and directed in a direction to iron the magnetic cards flat to the gate floor. Also disclosed is a concept for removing the normal force and moving the tray or floor of the card feeder to allow the insertion of magnetic cards into position for subsequent feeding.

With reference to Figure 1, the magnetic card feeder 10, together with the normal force system 12, is shown in its operating position to feed magnetic cards 14 from their rest position on tray 16. Endless feed belt 18 is supported by and around rotatably mounted pulleys 20 and 22, one of which is driven by conventional means (not shown). Magnetic cards 14 rest on tray 16 and gate floor 24. Deadweight 16 is positioned to rest on the forward portion of cards 14 near gate floor 24 and gate disk 28. Deadweight 26 provides two forces, which are positioned normal to the cards 14. Normal force 30 forces magnetic cards 14 flat with respect to gate floor 24 so the bottom magnetic card 14 will pass through the aperture formed by the gate floor 24 and the gate disk 28 when feed belt 18 is driven to feed a magnetic card 14 from the magnetic card feeder 10. Normal force 32 is positioned to force the bottom magnetic card 14 against feed belt 18 so the bottom magnetic card 14 will be fed from the magnetic card feeder 10 when the feed belt 18 is activated for feeding a magnetic card. An aperture 34 is provided in tray 16 to allow feed belt 18 to be in contact with the lower magnetic card 14.

With reference to Figure 2, the magnetic card feeder 10 is shown in the position to allow insertion of magnetic cards 14 into the feeder 10. Door 36 is rotated CW about pin 38, which positions lift cam 40 under tray 16 such that the end o...
