Abstract

A card picking mechanism shown at A includes a transversely aligned pair of thin, flexible, low inertia drive bands 3 that are each mounted about rollers 4 and 5 and secured to move in unison with roller 4. Bands 3 each carry a picker knife 6 with the generally horizontal band stretch 7 reciprocating as roller 4 angularly oscillates to pick the lowermost card from a deck positioned in hopper 8. Cards are driven beneath throat knife 9 to be transported by continuously running roll 10 and cooperating idler 11.

Card Picker Knife System

A card picking mechanism shown at A includes a transversely aligned pair of thin, flexible, low inertia drive bands 3 that are each mounted about rollers 4 and 5 and secured to move in unison with roller 4. Bands 3 each carry a picker knife 6 with the generally horizontal band stretch 7 reciprocating as roller 4 angularly oscillates to pick the lowermost card from a deck positioned in hopper 8. Cards are driven beneath throat knife 9 to be transported by continuously running roll 10 and cooperating idler 11.

Drive arm 12 rotates continuously in unison with shaft 13, causing the drive magnet arm 14, connected through drive link 15 to angularly oscillate about the axis of shaft 16 upon which it is supported by bearing 17. Clamp arm 18 is secured to shaft 16 for unitary motion therewith and carries an armature 19 disposed between hold magnet poles 20 and the poles 21 of drive magnet which forms a portion of drive magnet arm 14. Normally hold magnet coil 22 is energized retaining armature 19, thereby holding armature 19, roller 4 and band 3 in a stationary position. Upon issuance of a feed command, hold coil 22 is de- energized and drive arm coil 23 is energized causing clamp arm 18 and roller 4 to oscillate in unison with arm 14 and bands 3 to reciprocate. As bands 3 move forward the lowermost card in hopper 8 is held down by a vacuum exerted through apertures 24 by vacuum shoe 25 to assure proper driving engagement between card and picker k...
