Description

[Detailed description of the invention] Industrial field of application The present application relates to a counterfeit coin sorting device, and particularly relates to a counterfeit coin sorting device that can detect unperforated coins, such as 100 yen coins, and coins with holes of the same diameter, such as 50 yen coins.
The present invention relates to a counterfeit coin sorting device intended to separate counterfeit coins made by wrapping a tape around the outer circumferential surface of yen coins and counterfeiting the diameter of the yen coins.

BACKGROUND ART Conventionally, in order to detect a coin with a hole and a coin without a hole, a control piece that extends in the vertical direction and has a protrusion that projects in the coin passage direction is provided, and when a cradle supports a coin with a hole, A coin sorting device in which the protruding portion faces the hole and the rotation of the cradle is prevented by tilting the control piece at this time is known, for example, in Japanese Utility Model Publication No. 11004/1983. .

Problems to be Solved by the Invention However, according to the conventional configuration, the middle part of the control piece extending in the vertical direction is tiltably supported, and a protrusion is provided at the upper end of the control piece, and a vertical weight is provided at the lower end of the control piece. Since the upper part of the control piece is in contact with the outer surface of the cradle, when this coin sorting device is tilted to the coin passage side, the control piece has a protruding part that does not hold the coins. It tilts away from the passageway, making it impossible to correctly detect the presence or absence of holes.
Also, if the coin is tilted to the opposite side of the coin passage,
The control piece has the risk of tilting so that its upper part presses against the cradle and restricting the smooth rotation of the cradle. It required advanced technology and had flaws that impaired reliability.

Means for Solving the Problems Therefore, in order to improve the above-mentioned defects of the conventional device, the present application provides a pair of support pieces, a weight, and a locking portion on the outer surface of the opening/closing plate operated by the return lever. a rotatable cradle having a rotatable cradle; a restriction hole that allows movement of the pair of branch pieces and projects toward the passage formed between the inner surface of the opening/closing plate and the frame; and a protrusion portion to be described later. and a through hole through which the push rod passes;
A control that is rotatably attached and has a protrusion that protrudes at a position facing the center of a specific coin supported by the cradle, and a claw piece that engages with the engagement part when the cradle is rotated. and a spring piece that constantly presses the control piece in the direction of the passage so that the protruding part crosses the passage and abuts the frame, and further includes a spring piece that presses the control piece in the direction of the passageway, and further The fixed cover facing the cradle is provided with a push rod that protrudes inward at a position facing the coin supported by the cradle.

For example, when a 100 yen non-perforated coin, that is, a genuine coin, falls into the passageway and is supported by the branch of the cradle, the control piece presses the protrusion protruding into the passageway, and the control piece presses the spring part. The cradle is tilted towards the cover against the arm, and in this state the cradle is rotated by the weight of the coin, and the specie supported by the arm is guided into a predetermined path.

On the other hand, when a perforated coin, i.e. a counterfeit coin, falls into the channel and is supported by a branch of the cradle, within the channel the protrusion faces into the hole of the coin and the control piece moves towards the cover. Since the cradle does not tilt, even if the cradle tries to rotate due to the weight of the coin, the rotation is prevented by the locking part between the locking part and the claw of the control piece, and the counterfeit coin is not supported. It is held in a cradle while being supported by one piece.

When removing the held counterfeit coins, the return lever is operated to activate the opening/closing plate. Then, the opening/closing plate moves toward the cover, enlarging the passage, and the push rod protrudes toward the passage through the through hole, so the counterfeit coins are pressed and separated by the support piece.
For example, you will be guided to the return aisle.
