METHOD AND APPARATUS FOR CONDITIONING 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 (1302) and move down the length of a perforated tumbler (1314), preferably without the use of gravity, such as under screw...

Beschreibung
Zusammenfassung:	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 (1302) and move down the length of a perforated tumbler (1314), 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 (1352). 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 (1922a), fins, ridges, dimples (1820), 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.
