摘要:
The present invention provides a coin counting and sorting module (100) comprising a coin sorter (102); a coin bowl (118) for receiving a deposited mass of coins to be sorted, said coin bowl (118) having an inner surface intended to be in contact with the coins to be sorted, the inner surface comprising a rotating surface (116) adapted for being rotated when the module (100) is in operation; a front coin sensor (108) for detecting and removing counterfeit coins; a coin separating rail knife (128) for receiving coins one by one at a first end (120) thereof from the rotating surface (116) and for guiding the coins past the front coin sensor (108); the coin sorter (102), the coin bowl (118), the front coin sensor (108), and the coin separating knife (128) being mounted on a front plate (126) of the coin counting and sorting module (100), wherein the coin counting and sorting module (100) also comprises an inclined rail block (112) for receiving accepted coins from the second end (114) of the coin separating rail knife (128) and forwarding these coins to the coin sorter (102), said inclined rail block (112) being mounted on the front plate (126) of the coin counting and sorting module (100), and where an anti-bounce block (110) is firmly fastened to the inclined rail block (112) by a finite number of fastening elements. The invention also provides a coin handling apparatus comprising such a coin counting and sorting module (100).

The apparatus is intended to determine the value of a batch of mixed coins inserted by the user into a hopper unit (1) in which there is a rotatable disc (2) for feeding the coins in single file past a coin discriminator (6) to an escrow region (11). The total value of the coins retained temporarily in the escrow region (11) is displayed on a suitable display to the user, who can then choose either to have the coins returned to him, or allow the transaction to proceed for which the coins are payment. The apparatus may be used in a bank to issue a receipt for coins inserted, or as a lottery machine to issue lottery tickets. The machine can be arranged to return the coins in the escrow automatically to the user if the value of such retained coins does not, after a certain time, fall within a preset range.

A coin (1) is tested for its thickness by bouncing a wave packet of ultrasound off the surface (1′) of the coin, and timing the arrival of an identifiable element (7) of the reflected wave packet at a sound receiver (Rx). A zero-crossing point (7) of the reflected wave packet is used as the element, and is detected by converting the output (B) of the receiver (Rx) into a rectangular waveform (C) by using a comparator (8), and then using a microcomputer (10) with a timing function to time a particular edge of the rectangular wave. A flip-flop (11) is armed by an arm signal (D) from the microcomputer to await receipt of that pulse edge, and the time of clearing of the flip-flop is measured by the microcomputer to determine the coin thickness. Measurements are also periodically made with no coin present of the position of the coin support surface (2) to take account of any change in position of the transmitter (Tx) and receiver (Rx).
