Examples

A specific embodiment of the present invention includes a turntable body provided in the base body 10 below the coin storage bucket 9, which is characterized by: (1) the turntable body is formed by a plurality of coin capture holes 11 uniformly distributed along the circumference of the turntable body; The coin catching tray 12 and the coin falling stop receiving plate 13 fixed below it are composed; (2) There is a coin slot 14 and a coin pusher which open to the outside of the turntable body between the bottom surface of the coin catching plate and the upper surface of the receiving plate. Guide body 15; (3) said turntable body is located above the base body, said turntable position receiving plate is provided with a circular through hole 16, and the base body corresponding to the coin outlet is provided with a downward through circular ring opening The convex body 17 is used to stop the bottommost part of the coin catching hole that moves with the turntable body. The coins are discharged along the guiding work of the coin exit slot 14 and the coin pushing guide 15 toward the coin exit.

The coin pushing guide 15 described above is disposed between the bottom ends of two adjacent coin capturing holes. The guiding working surface of the coin pushing guide is arc-shaped and extends from the position near the middle of the turntable body to the outer edge of the turntable in a counter-rotating direction to the turntable body. Outer circumferential surface.

5 The center of the turntable body is connected with the motor driving mechanism 18 on the machine body. The coin guide is provided with a channel 19 with an opening facing the annular opening of the receiving plate, so that the turntable body can follow the machine when it rotates. The convex body on the seat passes.

In order to allow the coins to be ejected smoothly, the above-mentioned slot is adapted to the thickness of a coin. During the coin dispensing process, when the coin does not fall into the bottom of the coin capture hole properly and cannot slide out of the coin slot, it will jam the turntable body, so the bottom side of the above-mentioned convex body is hinged in the slot cavity 20 of the base body. The bottom of the groove cavity is provided with a return spring 21 acting on the lower side of the convex body. When the coin slot is clogged, the convex body compresses the reset spring 21 under the reaction force of the coin, and it rotates to make way around the hinge point with the base body to release the blocking effect on the coin in the coin capture hole. Make the turntable body continue to rotate (as shown in Figure 8, the arrow in the figure indicates the running direction of the turntable body, 22 is the coin that has not completely fallen on the receiving plate at the bottom of the coin capture hole), thereby preventing the turntable body from being stuck15 The phenomenon.

During work, in order to make coins of different denominations with large diameter differences reliable, the coin-blocking working surface of the convex body should be wide, but at the same time, the convex running channel 19 on the coin guide is also wide. The phenomenon that small-diameter coins are stuck in the channel is easy to occur, so the top of the convex body is provided with a groove 23, and the slot of the coin pushing guide body facing the annular opening of the receiving plate is provided above the convex body groove. 'S anti-coin stop 24.

Z0 In order to improve the efficiency of coin capture and reduce the probability of blockage of the coin capture hole, the upper surface of the above-mentioned turntable body has an inverted tapered surface with a high outer edge and a low center portion, thereby solving the contradiction between the inclination of the turntable body and the efficiency of coin capture It is good for coins lying flat on the working surface of the turntable body to fall into the coin catching holes, but it is not good for upright coins to change their attitude, and the inclination angle is large, and vice versa). In order to make it easier for coins to be captured by the coin catching hole, a coin catching introduction chute 25 is provided on the front side of the upper edge of the coin catching hole toward the direction of operation, and a coin overflow chute 26 is provided on the rear side, so that it cannot lie flat. The coins in the coin catching hole can overflow during the rotation of the turntable body, so as not to block the coin catching hole.

In order to control the width of the coin outlet channel to accommodate coins of different diameters, a pair of elastic swing arm assemblies 29 are hinged on both sides of the coin outlet channel 28 on the seat 27 on the periphery of the turntable body of the machine body. The two swing arms 29 of the module are controlled by the spring 30 to face each other in the center of the coin outlet channel. In the present invention, the coin outlet channel 28 It is located on the lowermost side of the slanted base body 10, which makes the overall structure more compact, and does not need to leave a coin space on the side during installation, so it is particularly suitable for group installation side by side.

In addition, a light reflecting mirror group 31 of the coin counting photoelectric sensor is provided above the coin dispensing channel, and a dustproof light transmission window 32 of the coin counting photoelectric sensor is provided below the coin dispensing channel, thereby avoiding the separate installation of the sensor at the relevant detection point This eliminates flying leads that are prone to failure, and enables all electrical control and detection components of this design to be concentrated on one control circuit board, simplifying production processes and improving work reliability.

For small-diameter coins, the smaller width of the coin outlet channel formed after the two swing arms are closed can prevent coins from leaking out after the turntable body stops rotating, while large-diameter coins can overcome the resistance of the spring under the push of the coin guide of the turntable body Make the swing arm wide and squeeze out. On the other hand, the elastic swing arm assembly also plays the role of guiding the movement direction of the coin to ensure that it passes through the coin counting channel to detect the light reflecting mirror.

The product of the utility model has a reasonable design, and its structure realizes the function of making a large number of coins with the same face value that are disorderly stacked in the coin storage bucket to accurately and accurately issue coins one by one according to real-time needs. As a basic functional component, this device can be used singly or in groups. It is used in vending machines and other equipment and occasions that need to find and exchange coins. It can realize the automation of coin exchange and exchange services, and its application prospects are very promising.
