Description

[Detailed description of the invention] Industrial application field The present invention is particularly concerned with sorting genuine coins and counterfeit coins in a sorting section, and then sorting coins with different diameters, intermediate-sized coins, and larger and smaller coins. The present invention relates to a coin diameter sorting mechanism in a coin sorting device.

BACKGROUND ART Conventionally, a cradle that receives coins introduced from an input slot and rotates, and a rotatable control lever that controls the rotation are disposed on a vertical base plate, and a rotation center of the cradle is provided. facing diagonally in an inactive state at an inner surface location away from the
The cradle is provided with two projecting rods that support large-diameter coins and are spaced apart to allow passage of small-diameter coins, and a locking protrusion is provided on the outer surface of the cradle, and the control lever is provided with a locking protrusion that supports the cradle. When a large-diameter coin is supported by the two rods and rotates together with the cradle, a locking portion that can lock with the locking protrusion in the rotational direction of the coin acts on the periphery of the coin to lock the locking portion. A coin sorting device which is provided with a restriction piece that applies a rotational force to the control lever in a direction in which the stop portion moves away from the locking protrusion is known, for example, in Japanese Patent Publication No. 56-51395.

Problems to be Solved by the Invention By the way, according to the above-mentioned conventional configuration, a large-diameter coin guided from a passage piece is supported by two rods provided on the inner surface of the cradle and rotated by its weight. At this time, the rod with the biased passage moves to a position facing the edge of the passage piece, and as a result, the large-diameter coin rotates with the cradle and moves away from the two rods before the cradle returns to the resting position. During the reversal process, subsequent coins guided by the passage piece become caught between the passage piece and one of the holders that has moved to the opposite position, preventing the cradle from restoring and preventing coin jams. There is a risk of triggering the cause.

Therefore, the present application aims to improve the above-mentioned fear of coin jamming.

Means for Solving the Problems In order to achieve the above-mentioned object, the present application provides a passage piece for guiding input coins to a vertical base plate, a cradle that receives and rotates the coin guided by the passage piece, and A rotatable control lever for controlling the rotation of the cradle is disposed on the inner surface of the cradle away from the center of rotation, and is diagonally opposed to the cradle in an inoperative state, supporting a large diameter coin and supporting a small diameter coin. two rods are provided protrudingly spaced apart from each other to allow coins to pass therethrough, and a locking protrusion is provided on the outer surface of the cradle, and the locking protrusion is provided on the control lever in the direction of rotation of the cradle. When a large diameter coin is supported by the two rods and rotates together with the cradle, the locking portion acts on the periphery of the coin to cause the locking portion to move away from the locking protrusion. A regulating piece is provided on the inner surface of the cradle to apply rotational force to the control lever in the direction of separation, and further, when the cradle is rotated, one holder provided on the cradle and a passage on one side of the passage are provided. This feature is characterized by the provision of a guide tongue piece located between the two pieces.

Function: The genuine coins that have been input into the coin sorting device and sorted by the sorting section are guided by the passage piece and guided between two receiving rods provided in the cradle.

When the specie just introduced is a large diameter coin,
The coin is supported between two receivers, and its weight causes the coin to rotate clockwise in the figure together with the cradle. Then, the circumferential edge of the large-diameter coin presses the regulating piece outward, so that the locking protrusion does not lock with the locking part, and the cradle rotates further and the coin is moved, for example, to the first passage. guided by.

Further, the small diameter coin guided into the cradle passes between two receivers and is guided, for example, to a second passage.

Furthermore, when the coin to be guided is an intermediate-sized coin, it is supported between the two rods and tries to rotate together with the cradle in this state, but the periphery of the coin does not act on the regulating piece. The control lever does not rotate, but the locking protrusion provided on the cradle locks with the locking portion provided on the control lever, preventing rotation of the cradle. The coins supported by the two rods of the cradle whose rotation is prevented are ejected into the return path by a conventional ejecting mechanism.

In the above, when the cradle rotates greatly together with the large-diameter coin, the guide tongue piece provided on the inner surface of the cradle is located between the passage piece and one of the receivers provided on the cradle on the side of the passage. There is no risk that subsequent coins guided by the passage piece will be caught between the passage piece and one of the holders of the cradle by the guide tongue piece during the restoration of the cradle, and therefore coin jamming will not occur. There isn't.

Try to rotate clockwise in the figure. However, since the peripheral edge of the coin c does not act on the regulating piece 10, the cradle 1
A locking protrusion 6 provided on the control lever 7 locks on a locking portion 9 provided on the control lever 7, thereby preventing the cradle 1 from rotating. The coin c, which is supported by the two rods 5a and 5b of the cradle 1 whose rotation is prevented, is ejected to the return path by a conventional ejection mechanism.

In addition, in the above, the large diameter coin a rotates together with the cradle 1, and in the middle of restoring the rotation,
When the subsequent coin is guided from the passage piece 11 to the cradle 1 side, one of the guide tongue pieces 3a moves between the passage piece 11 and the receiving rod 5a near the passage piece 11, as shown in FIG.
Since the subsequent coin is located between the passage piece 11 and
There is no risk of the coin b getting caught between the two receivers 5a and one receiver 5a, and due to the formation of the other guide tongue 3b, small-diameter coins b passing through the two receivers 5a and 5b can be As shown in FIG. 7, the discharge guidance in the direction of arrow B is smoothly performed.

Effects of the invention As described above, the present application does not restrict the rotation of the cradle when sorting large-diameter coins and small-diameter coins, but only controls the rotation of the cradle when a coin of intermediate size enters the coins. Since it has a restraining structure, it is extremely effective as a mechanism for sorting two types of coins with different diameters.Furthermore, according to the present application,
On the inner surface of the cradle, when the cradle rotates, a guide tongue piece is provided that is located between the passage piece and one of the holder rods provided on the cradle, so that when the cradle rotates, the cradle rotates together with large-diameter coins. There is no risk that subsequent coins will be caught between one holder of the cradle and the passage piece by the guide tongue piece in the process of restoring the coins, and the cause of coin jams can therefore be eliminated.
