Card snuffler with gravity feed system for playing cards
View Patent ↗A card feed system for feeding cards into a card handling system. The card feed system includes a card input compartment with a playing card support surface, a front wall, a rear wall and two side walls. The playing card support surface slopes toward the front wall at an angle between 12 degrees and 22 degrees. A slot is provided in the front wall to allow single cards to pass into the card handling system. The card feed system also includes a card moving system to advance cards through the slot.
1. A feed system for feeding playing cards into a card handling system, the feed system comprising:
a support frame;
a playing card input compartment having a playing card support surface, a front wall, a rear wall and two side walls;
the playing card support surface having a slope toward the front wall of between 12 and 22 degrees with respect to the horizontal;
the front wall having a slot to allow single playing cards to pass from the playing card support surface through the slot into the card handling system;
a playing card moving system associated with the playing card input compartment to advance single playing cards through the slot;
wherein playing cards in the playing card input compartment are pressed against the playing card moving system by gravity and without other mechanical pressure; and
wherein a blocking element is mounted for pivotal rotation with respect to the support frame, wherein in a first position the blocking element prevent a card from passing through the slot and in a second position the blocking element allows a card to pass through the slot.
2. The feed system of claim 1 , wherein the blocking element comprises at least one blocking lever.
3. The feed system of claim 2 , wherein the at least one blocking lever has an elongated body, and further comprising a pivot pin, wherein one end of the elongated body is mounted for rotation about the pivot pin.
4. The feed system of claim 3 , wherein an axis of rotation of the pivot pin is spaced apart from the slot.
5. The feed system of claim 1 , wherein the blocking element comprises at least two blocking levers.
6. The feed system of claim 1 , wherein the playing card moving system comprises at least one feed roller that extends through the playing card support surface to contact a lowermost card in the playing card input compartment.
7. The feed system of claim 1 , further comprising a guide fixedly mounted to the rear wall.
8. A method of transporting cards, comprising:
supporting cards in a playing card input compartment with a declining support surface at an angle between 12 and 22 degrees with respect to the horizontal;
providing a card slot in a front wall of the playing card input compartment of a size sufficient to allow a single card to pass;
providing a card mover comprising at least one card roller that extends through the declining support surface for contacting a lowermost card on the declining support surface; and
controlling movement of cards out of the playing card input compartment by blocking and unblocking the card slot.
9. The method of claim 8 , wherein the card mover comprises a pair of spaced apart rollers.
10. The method of claim 9 , wherein the rollers are positioned to move a lowermost card when the card slot is unblocked.
11. The method of claim 8 , further comprising blocking and unblocking the card slot with at least one blocking lever.
12. The method of claim 11 , further comprising rotating the at least one blocking lever about a pivotal axis to block and unblock the card slot.
