Abstract

Disclosed is a mechanism for singling bills being fed out of a stacker or cartridge by pick rollers embedded with diamonds and stop rollers covered with rubber in a bill-handling unit, such as the bill- dispensing machine. By pushing the stop roller against the metal pick roller directly, the bill-singling mechanism can be adjustment and maintenance free.

Bill-Singling Mechanism

Disclosed is a mechanism for singling bills being fed out of a stacker or cartridge by pick rollers embedded with diamonds and stop rollers covered with rubber in a bill-handling unit, such as the bill- dispensing machine. By pushing the stop roller against the metal pick roller directly, the bill-singling mechanism can be adjustment and maintenance free.

This bill-singling mechanism shown in the side view of Fig. 1 and the front view in Fig. 2 consists of three kinds of rollers: (1) metal pick roller 1 is embedded with diamond particles on a part of the periphery, which enables high co-friction force against bills when an appropriate pressure exists, (2) stop roller 2, which surface is covered by rubber, does not rotate in the bill feed direction. Spring 4 force keeps stop roller 2 against metal pick roller 1, and (3) subroller 3 is synchronously rotated with metal pick roller 1 to help bills to be fed. A part of subroller's periphery is made of rubber. As the stop roller is biased against the pick roller with an appropriate force, the stop roller rubber does not wear and the ink of bill does not adhere to the surface of pick roller rubber.

This mechanism can be free from requiring periodical maintenance because:
1. Abrasion of the stop roller rubber against the diamond particles is very little. As the stop roller is pushed against the pick roller by spring tension directly, the small amount of abrasion of the rubber has n...
