Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a coin push-up guide device. More specifically, the present invention relates to a coin push-up guide device that is provided in the middle of a guide of a coin feeding device, particularly an upward guide, to pass coins only in the feeding direction and prevent the coins from returning in the opposite direction.

[Conventional technology] Utility Model No. 59-37667 as a conventional coin feeding device
There is one shown in the publication. As shown in Figure 1 of the above-mentioned publication, in this device, the coins sent from the upward guide are collected in a lateral hopper, and then sent from the lateral hopper in a horizontal direction on a lateral guide. The coins are distributed to each game machine using a coin takeout device provided at a suitable position on the lateral guide. Although the means for feeding coins into the upward guide is not specified, a hopper device is usually used.

In this device, the ascending guide is a guide rail with a C-shaped cross section, and the coins are pushed up while being lined up in a row.

[Problems to be Solved by the Invention] In the conventional coin feeding device, the ascending guide is a mere guide rail and does not itself have the function of supporting the coins inside. Therefore, Hoppa, who is responsible for sending coins to the ascending guide,
Even when the coin is not being fed, it must support the weight of the coin to prevent it from falling. Furthermore, since a falling load is constantly acting when driving the coin upward, there is a problem in that the load becomes large and a large driving force is required. Furthermore, since the coin is pushed in with a large force, the coin itself is easily bent or deformed, which causes a problem in that it is likely to become jammed in the guide.

In view of the above circumstances, it is an object of the present invention to provide a coin push-up guide device that is effective in reducing the coin push force of the ascending guide and preventing coin deformation.

[Means for Solving the Problems] The coin push-up guide device of the present invention includes an ascending guide for guiding coins that are pushed up sequentially from below to above in a line, and a reverse movement preventive device provided in the middle of the ascending guide. The backlight prevention device includes a support part provided on the ascending guide, an arm member rotatably provided on the support part and extending in the coin traveling direction, and a tip of the arm member is a guide member. a biasing member for elastically biasing the arm member so as to be pressed against the arm member; and two claws formed at the tip of the arm member and inserted into gaps between coins in the guide that are adjacent to each other. The claw has a lower surface formed in a tapered shape and an upper end surface formed flat, and a groove into which the tip of the claw sinks is formed in the guide surface of the ascending guide facing the claw. The configuration is as follows.

[Operation and Effects of the Invention] In the coin push-up guide device of the present invention, a large number of coins fed into the upward guide by the vertical feed hopper are pushed up one after another in a state where they are packed in a line.

The weight of the coins in this ascending guide is supported by a reverse movement preventer having a tab that is inserted into the gap between adjacent coins. Coins are sent one after another to the entrance of the ascending guide, but 1
The coins in the upward guide will no longer descend between the time one coin is sent in and the next coin is sent in.

The anti-reverse tool of the present invention has a short operating distance because the claw moves at right angles to the guide, and the operating speed is fast due to the elastic bias, so when the coin passes over the top surface of the claw, it instantly moves downward. It protrudes and supports a coin. Therefore, even if coins are sent at high speed, the device will surely follow and operate, and even if a large number of coins are sent in a row, each coin can be supported reliably. Then,
As soon as the coin feeding is stopped, malfunctions such as coins falling in the guide will not occur.

Furthermore, since the arm extends in the direction of coin travel, when the coin presses the bottom of the claw, only a tensile force is applied to the arm, and no force is applied to bend the arm, so it can be used for a long time. However, no deformation occurs. Furthermore, when the tab supports the coin, the tip of the tab sinks into the groove of the guide surface of the guide, so there is no problem such as the tip of the tab being scraped by the coin and becoming deformed. Therefore, the present invention is durable enough to withstand long-term use. Furthermore, the feeding power of the vertical feed hopper is reduced, and smooth pushing up operation is performed.

[Example] Next, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view showing one embodiment of the coin push-up guide device of the present invention, FIG. 2 is a front view of the coin push-up guide device shown in FIG. 1, and FIGS.
The figures are a sectional view taken along line X-X and Y-
The Y-line sectional view and FIG. 5 are schematic front views showing the entire coin feeding device using the present invention.

First, the entire coin feeding device P in which the coin push-up guide device of the present invention is used will be explained based on FIG.

In FIG. 5, the coin feeding device P has a vertical feed hopper 1 placed on a floor F and a horizontal feed hopper 2 placed above the vertical feed hopper 1. An upward guide 3 extends upward from the outlet 1a of the vertical feed hopper 1 and reaches the horizontal feed hopper 2. A lateral guide 4 extends substantially horizontally from the lateral feed hopper 2. In the middle of the lateral guide 4, coin ejectors 7 are provided at desired intervals for distributing coins C to a coin lending device 5 or a game machine 6, which are coin supply destinations. Furthermore, an intermediate drive device 8 is provided in the middle of the lateral guide 4 for driving the coin C within the lateral guide 4 in the feeding direction. In FIG. 5, reference numeral 9 denotes a belt conveyor for collecting coins C from the coin dispenser 5 or the game machine 6 and returning them to the vertical feed hopper 1.

Note that a polisher (not shown) that can automatically polish randomly sent coins may be interposed between the belt conveyor 9 and the vertical hopper 1, or a polisher (not shown) may be provided in the middle of the upward guide 3 in an aligned state. A polisher (not shown) that can polish the surface of the coin C to be sent may be provided. As a result, coins can be polished automatically while the coin feeder is in operation, which prevents coins from clogging the guide and ensures safe operation of the coin feeder. .

In the coin feeding device P configured as described above, the coins C that are manually fed to the vertical hopper 1 or collected by the belt conveyor 9 are sent out by the vertical hopper 1 and are sent upward by the ascending guide 3. After being guided to the hopper 2, it is retained in the traverse feed hopper 2. Further, the coins C in the traverse feed hopper 2 are guided by a lateral guide 4 and are transferred to the end portion 11 of the line while being driven by an intermediate drive device 8 along the way. During the transfer, the coins C are supplied to the coin dispenser 5 or game machine 6 in an aligned state by a coin ejector 7 that opens upon receiving a signal from the coin dispenser 5 or game machine 6 when the remaining amount is low. be done. At this time, the required number of coins can be supplied to the coin lending device 5 or the like while being counted.

The lateral guide 4 is suspended from, for example, a groove shaped steel with a lip placed in the ceiling, or is fixed by being attached inside the groove.

The basic structure of both the vertical hopper 1 and the horizontal hopper 2 is the same as that of a commercially available hopper feeder. A direction change guide 14 is provided for changing the direction.

A push-up guide device 20 according to the present invention is provided near the lower end of the ascending guide 3.

The ascending guide (hereinafter simply referred to as guide) 3 has a coin C as shown in its cross section in Figures 3 and 4.
It is formed into a flat C-shape to guide both side edges of. Therefore, the only parts visible to the outside in the gaps between the coins C are two small triangular parts, which are extremely narrow (see Figure 2).

Therefore, the retrograde prevention device described in detail below can be suitably employed.

As shown in FIG. 1, the reverse movement prevention device 21 according to the present invention includes a support portion 23 fixed to the surface of the guide 3 with a bolt 22, and a pin 24 attached to the support portion 23.
an arm member 25 rotatably attached to the
It has a biasing member for biasing the arm member 25 so as to constantly press the tip of the arm member 25 toward the guide 3 side. In the reverse movement prevention device 21 shown in FIGS. 1 to 4, a torsion coil spring 26 is employed as the biasing member.

The support part 23 consists of a bottom part 28 extending over the opening 27 on the surface of the guide 3, and two rising parts 29 rising from the bottom part 28 at regular intervals. The pin 24 has a rising portion 2
9 is inserted at a position a certain distance away from the guide surface 30 of the guide 3. The arm member 25 consists of two plate parts 31 and a spacer 32 that holds the plate parts 31 at an appropriate distance. The arm member 25 is moved from the support portion 23 in the direction in which the coin flows (arrow A in FIG.
A claw 33 is formed at the tip of the arm member 25.

The claw 33 is formed as two protrusions that protrude toward the guide 3 so that it can be inserted into the gap between adjacent coins C as shown in FIG. The upper end surface 34 that presses the
It is formed so that it is approximately perpendicular to the guide surface 30 when it comes into contact with the guide surface 30. Furthermore, the upper end surface 34
A tapered surface 35 is formed on the inside so that it can reliably support a circular coin.

As shown in FIGS. 1 and 4, when forming a groove 36 on the guide surface 30 of the guide 3 to receive the tip of the claw 33 so as to sink it from the guide surface 30, the outer periphery of the coin C This is preferable because the engagement between the surface and the claw 33 is ensured.

The lower surface 37 of the protrusion constituting the claw 33, that is, the portion that the pushed-up coin C hits from below, is formed into a tapered shape so that the pushed-up coin can easily pass through.

In the retrograde prevention device 21 shown in FIG.
A torsion coil spring 26 wound around the outer periphery of the pin 24 is used as a biasing member for biasing the arm member 25 in the direction of arrow B. One end 38 of the torsion coil spring 26 is engaged with a spacer 32 provided on an extension portion 39 extending from the support portion 23 in a direction opposite to the coin traveling direction, and the other end 40 is engaged with the bottom portion 28 of the support portion 23, for example. engaged.

However, the biasing member in the present invention is not limited to the torsion coil spring 26, but may be any member that can bias the arm member 25 to rotate in the direction of arrow B. For example, various biasing members may be employed, such as a tension spring for pulling the tip of the arm member 25 in the direction of the guide 3 or a compression spring for biasing the extension portion 39 away from the guide 3. .

Furthermore, the shapes of the arm member 25 and the support part 23 are not particularly limited to those shown in FIGS. An arm member or a support part can be used.

Next, the operation of the coin push-up guide device constructed as described above will be explained.

When no external force is applied, the front surface 41 of the claw 33 is in contact with the guide surface 30 of the guide 3 or the groove 36 formed in the guide surface. This is due to the urging force of the torsion coil spring 26.

The coin C pushed up from below pushes up the coin above the claw 33 and pushes the lower surface 37 of the claw 33 upward. As a result, the arm member 25 rotates in the direction of arrow D, allowing the coin C to pass through. After passing, the arm member 25 rotates in the direction of arrow B again.

The coin C that passed under the claw 33 is
When the driving force pushing it up from below weakens, it tries to fall downward, but it comes into contact with the upper end surface 34 or tapered surface 35 of the claw 33, and tries to rotate the claw 33 in the direction of arrow B. However, since the front surface 40 of the claw 33 is in contact with the guide surface 30 or the like, the claw 33 does not rotate in the direction of the arrow B and can reliably support the weight of the coin C.

The coin push-down guide device of the present invention is installed near the exit of the vertical feed hopper 1 as shown in FIG. They may be provided along the same line.

In that case, the reverse movement preventive devices 21 may be provided alternately on the front side and the back side of the guide 3, or the backward movement preventive devices 21 may be provided on the front side and the back side of the guide 3 at the same position.

In addition, several retrograde prevention devices 21 are attached to a circulating endless chain or a rotating disc, etc.
The coin may be actively driven upwards.

Also, the horizontal guide 4 in Fig. 4 is the coin C.
When the coin pushing device is arranged in an oblique direction such that it rises toward the feeding direction, the coin pushing device may be installed along the transverse guide 4.
