Method and apparatus for conditioning coins prior to discrimination
View Patent ↗A coin conditioner is provided for cleaning or otherwise conditioning coins in a coin discriminator apparatus prior to transfer to a coin sensor. Coins enter through a feed tray and move down the length of a perforated tumbler, preferably without the use of gravity, such as under screw force, mechanical or centrifugal force. The spinning tumbler is preferably rotated about its longitudinal axis by a motor. In one embodiment, a blower or vacuum draws or moves air from one area to another, with the air preferably being filtered. As coins move through and down a tumbler, projections such as vanes, fins, ridges, dimples, spines or other raised features cause mechanical agitation and/or abrasion as coins are lifted and dropped while passing longitudinally through the tumbler. The coins are conditioned and non-coin matter is collected as it is separated and/or abraded from the coin surfaces. Tumbler perforations permit non-coin matter to pass through the perforations into a collection tray or other apparatus and/or are collected into filter media as a result of the air flow. In one embodiment, the air pressure system eliminates or reduces the occurrence of low density or light non-coin matter, such as hair or dust, and prevents these materials from settling or being carried through downstream portions of the coin processing system.

11. An apparatus for issuing a redeemable voucher, the apparatus comprising:
means for receiving a plurality of randomly oriented coins from a user;
means for separating debris from the plurality of coins received from the user, the means for separating defining an interior space having a flat interior surface with at least a first opening sized to let dirt and other non-coin items exit the means for separating to the exclusion of any one of the plurality of coins;
means for lifting the plurality of coins in the interior space of the means for separating debris, the means for lifting including a first portion attached to the flat interior surface and a second free end portion extending inwardly from the first portion and away from the flat interior surface at an angle relative to the first portion;
means for discriminating the plurality of coins received from the user to determine a total of acceptable coins; and
means for dispensing a redeemable voucher for at least one of the total and a value related to the total.
12. The apparatus of claim 11 , further comprising motive means operably coupled to the means for separating, wherein the motive means are configured to move the means for separating to cause at least some of the plurality of coins to exit the interior space.
13. The apparatus of claim 11 , further comprising means for reversing the means for separating in response to sensing a slowing or halting of movement of the means for separating.
14. The apparatus of claim 11 , further comprising means for flowing air through the means for separating.
15. The apparatus of claim 11 wherein the means for dispensing a redeemable voucher include means for dispensing a voucher that is redeemable at a point of sale in a non-bank retail location for products sold at the retail location.
16. The apparatus of claim 11 wherein the means for dispensing a redeemable voucher include means for dispensing a voucher that includes a security feature configured to prevent voucher fraud.
17. The apparatus of claim 11 , further comprising:
means for displaying at least one of the total and a value related to the total, wherein the means for dispensing a redeemable voucher include means for dispensing a redeemable voucher in response to a first user selection accepting of at least one of the total and the value related to the total; and
means for returning the plurality of held coins to the user in response to a second user selection rejecting at least one of the total and the value related to the total.
18. A method for counting coins, the method comprising:
receiving a randomly oriented plurality of coins in a coin input region;
transferring the plurality of coins from the coin input region to a debris separation device positioned to receive coins from the coin input region, the debris separation device having at least a first flat wall with a plurality of holes sized to prevent passage therethrough of the smallest coin of the plurality of coins, the debris separation device further including at least a first vane having a lower portion attached to an interior surface of the first flat wall and an upper free end portion extending inwardly from the lower portion and away from the first flat wall at an angle relative to the lower portion;
moving the debris separation device to agitate the plurality of coins and let non-coin matter within the debris separation device pass through one or more of the plurality of holes and exit the debris separation device;
transferring the plurality of coins from the debris separation device to a coin discriminator, the coin discriminator including at least one coin sensor configured to discriminate the plurality of coins to determine a total; and
dispensing a redeemable voucher for at least one of the total and a value related to the total.
