Automatic discard rack
View Patent ↗A device, referred to as the “automatic discard rack” for use on casino gaming tables or elsewhere to hold and mix playing cards, such as cards discarded following each hand of a played game. The device includes features for randomly picking up a portion of cards placed in the rack to allow cards inserted into the rack to be randomly inserted into cards already in the rack, and the cards to be repeatedly mixed by the device. Variations of the device include a housing, clamping portion, a moveable lifting portion for moving the clamping portion, a moving engine for causing the movement, including clamping, of the clamping portion, a controller for controlling all movement, sensor for sensing placement of cards in the device and initiating movement, a “kill switch,” and an on/off switch.
1. An automatic card mixing device, comprising:
a base;
a moving engine attached to the base;
a movable lifting portion coupled to the moving engine, the movable lifting portion being movable among a plurality of random locations and a stop location;
a clamping device attached to the movable lifting portion;
a sensor for sensing the placement of at least one card on the base; and
a controller for controlling the movable lifting portion and the clamping device;
wherein, upon the sensor sensing the placement of at least one card on the base, the controller causes the movable lifting portion to move to one from the plurality of random locations, the clamping device to clamp, and the movable lifting portion to move to the stop location.
2. The device of claim 1 , further comprising at least one side attached to the base, wherein the base with the attached at least one side has an opening for receiving the at least one card for placement on the base.
3. The device of claim 1 , wherein the controller includes a randomizer.
4. The device of claim 1 , wherein the clamping portion comprises a pair of arms.
5. The device of claim 4 , wherein each of the pair of arms includes a clamp end.
6. The device of claim 5 , wherein the clamp end comprises rubber.
7. The device of claim 4 , further comprising:
a knife portion attached to at least one of the pair of arms.
8. The device of claim 1 , wherein the moving engine and the controller are attached to a power supply.
9. The device of claim 8 , wherein the moving engine and the processor are attached to the power supply via a coupling.
10. The device of claim 9 , wherein the coupling is an alternating current (AC) power connector.
11. The device of claim 1 , further comprising a housing for enclosing the moving engine and the controller.
12. The device of claim 1 , wherein the sensor comprises an electric eye.
13. The device of claim 2 , further comprising a cover attached to the at least one side.
14. The device of claim 1 , wherein the movable lifting portion comprises a ratcheting mechanism.
15. The device of claim 1 , wherein a delay occurs prior to the processor causing the movable lifting portion to move to a random location.
16. The device of claim 15 , wherein the delay is about five seconds.
17. The device of claim 1 , wherein the moving engine comprises an electric motor.
18. The device of claim 1 , wherein the controller comprises a processor.
19. An automatic card mixing device, comprising:
a base;
a motor attached to the base;
a movable lifting portion attached to the base, the movable lifting portion being movable among a plurality of random locations and a stop location;
a clamping device attached to the movable lifting portion;
a sensor for sensing the placement of at least one card on the base; and
a processor for controlling the movable lifting portion and the clamping device;
wherein, upon the sensor sensing the placement of at least one card on the base, the processor causes the movable lifting portion to move to a random location, the clamping device to clamp, and the movable lifting portion to move to the stop location.
20. A method of automatically mixing a plurality of cards, the method comprising:
placing at least one of the plurality of cards in a card mixing device, such that a pile of cards is placed in the mixing device on a base portion of the card mixing device, the pile of cards including the plurality of cards;
randomly determining a height above the base portion;
a grasper within the card mixing device moving from a predetermined location relative to the base portion to the randomly determined height;
the grasper grasping for the plurality of cards at the randomly determined height; and
the grasper returning to the predetermined location.
