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.

Method and apparatus for conditioning coins prior to discrimination

Methods and systems for cleaning coins and issuing a redeemable voucher for same. In one embodiment, an apparatus for issuing a redeemable voucher includes a coin input region configured to receive a plurality of coins, and a user interface configured to receive a request for a redeemable voucher. The apparatus can further include a debris separation device having a first opening configured to receive the plurality of coins from the coin input region, and at least a first wall forming an interior surface and an exterior surface. The first wall of the debris separation device includes at least one second opening smaller than the first opening and sized to prevent passage therethrough of the smallest coin of the plurality of coins. A driver can be configured to move the debris separation device and agitate the plurality of coins.

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 centrifuigal 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.

An automatic response to a detected jam or other slowing or stoppage in a coin handler, such as a coin counter and/or sorter, is provided. Such automatic dejamming is particularly useful for unattended operation of coin handlers. Preferably the response is substantially flexible, such as by providing different responses depending on the type of jam and/or the history of jamming. In one embodiment, potential responses include initiating a wait period, providing mechanical energy (such as causing vibration by controllably activating transducers, preferably addressable transducers which perform a second function in the apparatus), and/or impact. When the coin handler uses a rail mechanism, reliable, reduced-jam operation is enhanced by a ribbed rail structure that reduces or minimized the amount of surface area in contact with the coin face, consistent with providing the support desired for assuring accurate counting. Preferably the ribs are relatively deep, and have a rounded profile.
