Abstract

Chip sorting devices include a rotatable disc having a plurality of wells for receiving chips therein, a plurality of channels for holding stacks of chips, at least one ejector for ejecting chips from the wells of the disc into the channels, and at least one removal lever associated with at least one of the channels. The removal lever has an arm configured to extend adjacent at least a portion of a stack of chips when the stack of chips is in a channel. Other chip sorting devices include a plurality of wells for receiving chips therein, a plurality of channels for holding stacks of chips, at least one ejector for ejecting chips from the wells of the disc into the channels, and at least one spring member configured to bias the ejector to a position.

Claims (24)

1. A chip sorting and stacking device, comprising:

a disc rotatable about an axis and comprising a plurality of chip receiving wells proximate an outer edge of the disc;

a plurality of channels each configured to hold a stack of chips;

at least one ejector for ejecting chips from the chip receiving wells of the disc into a channel of the plurality of channels; and

at least one removal lever associated with at least one channel of the plurality of channels, the at least one removal lever having an elongated pivot arm configured to extend adjacent at least a portion of a stack of chips when the stack of chips is held within the at least one channel of the plurality of channels;

wherein the at least one removal lever is mounted to a body configured to slide within a groove associated with the at least one channel of the plurality of channels.

2. The device of claim 1 , further comprising an adjustment device configured to adjust a number of chips in the stack of chips that may be displaced upon causing the pivot arm to pivot against the at least a portion of the stack of chips.

3. The device of claim 2 , wherein the adjustment device comprises an adjustable screw.

4. The device of claim 1 , further comprising a sensor configured to detect when the stack of chips comprises a predetermined number of chips.

5. The device of claim 4 , further comprising a microprocessor configured to prevent the at least one ejector from ejecting additional chips into the stack of chips when the sensor detects that the stack of chips comprises the predetermined number of chips.

6. The device of claim 1 , further comprising a spring member configured to bias the at least one removal lever in a position relative to the stack of chips when the stack of chips is held within the at least one channel of the plurality of channels.

7. A chip sorting and stacking device, comprising:

a disc rotatable about an axis and comprising a plurality of chip receiving wells proximate an outer edge of the disc;

a plurality of channels each configured to hold a stack of chips;

at least one ejector for ejecting chips from the chip receiving wells of the disc into a channel of the plurality of channels; and

at least one spring member located to bias the at least one ejector against a rotatable non-circular cam member positioned to cause the at least one ejector to move between a retracted position and an extended position responsive to rotation of the cam member.

8. The device of claim 7 , wherein the at least one ejector is biased to the retracted position in which the at least one ejector is retracted from the disc.

9. The device of claim 7 , wherein the at least one ejector is configured to eject chips from the plurality of chip receiving wells of the disc directly into the channel of the plurality of channels.

10. The device of claim 7 , wherein rotation of the disc causes rotation of the rotatable non-circular cam member when the at least one ejector is actuated.

11. The device of claim 7 , further comprising a roller mounted to the at least one ejector, the roller configured to roll over a surface of the rotatable non-circular cam member as the rotatable non-circular cam member is rotated.

12. The device of claim 7 , further comprising a gaming chip characteristic identification system positioned adjacent the disc.

13. The device of claim 10 , further comprising:

a gear associated with the disc; and

a pinion associated with the rotatable non-circular cam member, the pinion engaged with the gear when the at least one ejector is actuated and disengaged with the gear when the at least one ejector is not actuated.
