JPH04114666U - Coin feeding disk of coin dispensing device - Google Patents

Abstract

(57) [Summary] [Purpose] To prevent a situation in which there are no coins in the coin receiving hole, and to prevent an increase in the load on the drive device caused by the increase in weight due to an increase in the number of coins held, and stop deviation due to an increase in inertia force. This is an attempt to solve these problems by reducing the weight of the coin feed disk itself. [Structure] The present invention is characterized in that the coin receiving hole of the coin feeding disk of the coin dispensing device is deep enough to accommodate three or more coins, and the coin feeding disk is made of a synthetic resin material.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention can be used for dispensing coins in game machines, vending machines, currency exchange machines, etc. A coin for dispensing one coin in the hopper of the coin dispensing device. This relates to the feeding disk.

0002

[Conventional technology]

Previously, this type of coin feeding disk was described in Utility Model Publication No. 58-19646. Something like that is known. Coin feeding disks of the format described in this bulletin As shown in Figure 6, the thickness of the coin feeding disk 1 is approximately equal to that of one coin. The coin feeding disk 1 is made of a metal disk with a certain thickness, and a plurality of coins can be stored in this coin feeding disk 1. Receiving holes 2 are provided through the coils at positions spaced apart from each other in the circumferential direction, and each adjacent coil A coin feeder with a thickness of approximately one coin is placed on the bottom surface of the coin feeder disk 1 between the coin receiving holes 2. A protruding piece 3 is provided for attaching the coin feeding disk to a rotating shaft (not shown). It has a central boss 4, and a trapezoidal protrusion 5 at the upper end of the central boss is connected to the coin feeding disk 1. It is protruded from the center of the top surface.

0003 The above-mentioned coin feeding disk was published in Japanese Patent Publication No. 55-48634 and Special Publication No. 48634. Used in a coin dispensing device as described in No. 63-36040, No. 5 As shown in the figure, inside the cylindrical hopper 5, on the hopper bottom plate 7 inclined with respect to the horizontal, A rotating shaft rotatably supported and driven by a motor 9 via a transmission gear device 10 A central boss 4 is attached to the hopper 8 as the coin feeding disk 1 rotates. - 6 is received in the coin receiving hole 2 and placed on the bottom plate 7 by the coin feeding piece 3. Push the coin forward and send one coin out of the hopper through the exit hole formed in the hopper peripheral wall. You can extrude them one by one.

0004 And, as a recent trend, this type of coin dispensing device, for example, is Miniaturization is required because it can be installed and used in a small space between coins per second to shorten the time to pay out a large amount of coins that are stored at a time. There is a demand for an increase in the number of coins that can be dispensed.

[0005]

[Problem that the idea aims to solve]

As a result of reducing the diameter of the coin feed disk in response to the above requirements, If the number of coin receiving holes that can be provided in the coin feeding disk is small, for example, three, Also, as a result of increasing the rotation speed of the coin feed disk, the inside of the coin receiving hole Coins entering the disk become difficult and the coin dispensing efficiency, that is, per one rotation of the disk, decreases. The number of coins thrown out has decreased, causing a problem where coins are not thrown out as calculated. There is. This invention is designed to solve these problems, especially for small-diameter coin feed disks. We provide coin feeding disks suitable for coin dispensing devices that rotate at high speed using This is what we are trying to do.

[0006]

[Means to solve the problem]

Therefore, according to the present invention, the plurality of coin receiving holes are spaced apart from each other in the circumferential direction. Place the coin feed disk, which is provided through the hole, on the bottom plate of the cylindrical coin hopper. The central boss of the coin feeding disk is connected to the rotating shaft of the drive device. In the coin feeding disk of the coin dispensing device, the coin receiving hole is It has a depth that allows three or more coins to be stacked, and the entire coin feeding disk It is characterized by being made of synthetic resin material.

[0007] Glass fiber-containing polyamide is suitable as the synthetic resin material.

[0008] An insert pin having a center hole into which the rotation shaft of the drive device is inserted is inserted into the center. It is best to install it by fitting it into the center hole drilled in the boss.

[0009]

[Effect]

According to the present invention, the depth of the coin receiving hole 2 can be increased by three or more coins stacked up. Due to this depth, a situation may occur in which there is no coin in the coin receiving hole. This improves coin dispensing efficiency and reduces the number of rotations of the coin feed disc. This ensures an increase in the number of coins paid out by increasing the number of coins.

0010 Furthermore, compared to conventional metal materials, the coin-feed disc is made from a lightweight material. By using a plastic material, the coin feed disc itself is lightweight. However, This occurs as a result of holding a larger number of coins in the coin receiving hole than in the past. This increase in weight is offset by the lighter weight of the coin feed disc itself. Despite the increase in the number of coins held in the receiving hole, the transmission gear 9 and the motor This prevents an increase in the load on the motor 10, and also prevents an increase in inertia and allows a predetermined number of coins to be collected. This ensures that the coin feeding disk can suddenly stop at the moment the coin is thrown out. to this Therefore, it is possible to ensure that a predetermined number of coins are thrown out.

[0011]

【Example】

An embodiment of the present invention will be described with reference to FIGS. 1 to 4.

0012 In the illustrated example, the coin feeding disk 1 is provided with penetrating holes at circumferentially spaced positions. The depth d of the three coin receiving holes 2 is as shown in Figure 3. It is large enough to fit inside. 4 is a coin holder on the bottom surface of the coin feed disk 1. A coin feeding piece protruding between two holes is shown.

[0013] The coin feeding disc 1 is made of glass fiber reinforced polyamide and the central boss 4 The rotation shaft 8 of the drive device 9, 10 of the coin dispensing device (see Fig. 5) is inserted into the center hole 11 provided in the The metal insert pin 12 into which the coin feed disc 1 is inserted It is inserted so that it can rotate.

[0014]

[Effect of the idea]

According to the present invention, it is possible to increase the probability that a coin always exists in the coin receiving hole 2. This increases coin dispensing efficiency and increases the number of coins held by the coin feeding disk. The increase in mass and inertia caused by This prevents an increase in the load on the drive device of the coin dispensing device, and It is possible to suddenly stop the coin feeding disk using the conventional control device when dispensing coins. This has the effect of ensuring an accurate number of coins to be paid out.
