Coin handling device with an improved lubrication system

A coin sorter system, comprising:

• a rotatable disc having a resilient top surface for receiving a plurality of coins thereon;
• a stationary sorting head having a lower surface being positioned generally parallel to the resilient top surface of the disc and spaced slightly therefrom, the lower surface of the sorting head having formed therein a queuing region for aligning edges of the coins on the top surface of the disc at a common radius, a periphery of the lower surface of the sorting head forming a plurality of exit stations for selectively allowing exiting of the queued coins based upon their respective diameters;
• a cavity formed in the lower surface of the sorting head;
• reservoir storing a lubrication fluid;
• a supply tubing for conveying the lubrication fluid from the reservoir to the cavity;
• and
• a control system regulating the flow of the lubrication fluid from the reservoir to the cavity via the supply tubing.

A method of lubricating a coin handling device including (a) a coin-driving member having a resilient surface, and (b) a stationary coin-guiding member having a coin-guiding surface opposing the resilient surface of the coin-driving member, the coin-guiding surface being positioned generally parallel to the resilient surface and spaced slightly therefrom, the resilient surface of the coin-driving member moving coins along the coin-guiding surface of the coin-guiding member, the method comprising the steps of:

• forming a cavity in the coin-guiding surface of the coin-guiding member;
• storing a lubrication fluid in a reservoir;
• coupling the reservoir to the cavity using a supply tubing;
• and
• regulating the flow of the lubrication fluid from the reservoir to the cavity via the supply tubing.
