Description

[Detailed description of the invention] "Industrial application field" The present invention allows coins or game coins, etc. accumulated in a coin accumulation tube to be thrown one by one by a coin feeding disc rotating inside the accumulation tube. This invention relates to a coin dispensing device that dispenses coins.

``Prior Art'' Conventionally, this type of device has a coin accumulation tube for accumulating coins and a flat coin feeding disk which are installed at an angle with respect to the horizontal line, and the coins are fed by the disk rotating within the accumulation tube. The coins are scooped up one by one, guided to a discharge guide member, and sent out to the outside via a coin delivery passage. FIGS. 9 and 10 show an example of the structure of such a coin dispensing device. That is, this device includes a main body part 2 equipped with a coin feeding disc 1 for scooping up coins C and sending them out to the outside, and a coin accumulating tube 3 connected to the upper side of this main body part 2 to accumulate and store the coins C. It is mainly composed of.

The main body section 2 includes a support main body 2a that rotatably supports the coin feeding disk 1 in a state inclined with respect to the horizontal line, and this support main body 2a
An electric motor M for driving the coin feeding disk 1 is attached to the lower surface of the support body 2a, and a coin feeding passage 4 is provided on the upper surface of the support body 2a to guide the coins C scooped up by the coin feeding disk 1 to the outside. is provided.

In the illustrated example, the coin feeding passage 4 has a structure in which the coins C scooped up by the coin feeding disc 1 and guided by the ejection guide member 4a are guided to the count switch 5 at the end of the passage. Specifically, it is mainly composed of a guide rail 4b erected on the upper surface of the support body 2a, and a lead plate 4c contiguous to the tip of the ejection guide member 4a and forming a passage for the coins C.

Note that a pressing spring 4d is attached to the guide rail 4b to press the coin C against the bottom surface of the coin sending passage 4, so that the coin C sent out by the coin sending disk 1 is replaced by the coin sent out after that. It is designed to ensure that it can be pushed out toward the passage 4 by C.

Further, on the upper surface of the coin feeding disk 1 that scoops up the coin C and sends it out to the outside, a plurality of locking pins 1a for locking the coin C on the disk are protruded along the circumferential direction. A stirring rod 6 is attached to the center of the plate 1 to prevent the coins C from getting caught in the collecting tube 3 (see FIG. 10).

On the other hand, the coin accumulation tube 3 that accumulates and accommodates the coins C is
As shown in FIG. 10, there is a hopper section 3a for storing coins C, and a support body 2a that supports the hopper section 3a.
It is composed of a cylindrical main cylinder part 3b for attachment to the main cylinder part 3b.

The hopper part 3a is supported by a leg plate 3c provided on its side surface via a screw 7 fixed to the upper surface of the main cylinder part 3b, and a coil spring 8 is interposed between the screw 7 and the leg plate 3c. The hopper section 3a is arranged so that the entire hopper section 3a can swing freely relative to the main cylinder section 3b.

Note that the lower end 3d of the hopper part 3a is located at the first
As shown in FIGS. 1 and 12, the diameter of the hopper 3a is enlarged in a taper shape, and the coin C in the hopper portion 3a can be dropped into the coin feeding disk 1.

According to the coin dispensing device having the above configuration, by rotating the coin dispensing disk 1 of the main body 2 in the counterclockwise direction,
The coins C in the stacking tube 3 are scooped up to the discharge guide member 4a while being locked to the locking pin 1a of the disc 1, and sent to the coin delivery passage 4 via the discharge guide member 4a.
Since the coins C stored in the stacking cylinder 3 can be smoothly and accurately delivered through the passage 4 through the delivery port at the tip thereof, the coins C can be pushed out to the outside through the delivery port. It is possible to count each sheet by a count switch 5.

Further, the coins C in the stacking tube 3 are, for example,
As shown in Fig. 1, a large number of coins are dropped from the lower end 3d of the hopper part 3a toward the coin feeding disk 1, but at this time, the hopper part 3a resists the coil spring 8 due to the dropped coins C. Since it moves in the direction of arrow A and widens the space into which the coins C are dropped, the coins C can be scooped up one by one between the tip of the hopper part 3a and the coin feeding disc 1.

"Problems to be Solved by the Invention" The present invention attempts to solve the following problems in the prior art described above.

First, in the device, as shown in FIGS. 11 and 12, between the lower end 3c of the hopper part 3a and the coin feeding disk 1, a large number of coins C are piled up, or a single coin C is When the hopper part 3a is squeezed or narrowed, the hopper part 3a pushes up against the biasing force of the coil spring 8 and acts to place the coin C on the coin feeding disk 1, but normally the hopper part Since a large number of coins C are stored in the hopper section 3a, a large amount of force is required to move the entire hopper section 3a, resulting in problems such as the need to increase the power of the electric motor M.

Second, as described above, the hopper section 3a stores a large number of coins C, and since the weight of these coins C is applied, the movement of the hopper section 3a becomes slow, and the lower end 3d of the hopper section 3a and the coins Even if the coin C caught between the feed disk 1 is scooped up and the hopper part 3a tries to return to its original position, it cannot return suddenly, and a large number of coins are collected again in a state wider than the initial gap width. C gets stuck, and by repeating this operation, finally the hopper part 3a
can no longer escape in the direction of arrow A, and as a result, there is a risk that the coin C will be caught and the electric motor M will be stopped.

Incidentally, if an attempt is made to reduce the weight of the hopper part 3a in order to solve the second difficulty,
The size of the hopper portion 3a must be made small, which causes problems such as the amount of coins C that can be collected is limited. In addition, in order to increase the amount of coins C accumulated, a method has been proposed in which an increase tank T is provided above the hopper section 3a, as shown in FIG. 13, for example. A supporting member 9 is provided separately from the portion 3a.
etc., and consideration must be given so that only the hopper part 3a can swing, so there is a gap between the upper part of the hopper part 3a and the volume increase tank T to allow the swing of the hopper part 3a. In some cases, the coin C may fall out from this gap, which is inconvenient. Moreover, when such an increase tank T is provided, if the hopper section 3a is clogged with foreign matter, the increase tank T must be removed and the foreign matter inside the hopper section 3a must be removed, which leads to problems such as poor maintenance. There is.

This invention was proposed in view of the above circumstances.
The purpose of this is to allow the coins in the coin stacking cylinder to be scooped up smoothly by the coin feeding disc without clogging or jamming the coins in the stacking cylinder, and to have an effect on the electric motor. By reducing the load on
Moreover, it is an object of the present invention to provide a coin dispensing device which can have a large hopper section for storing coins and is easy to maintain.

``Means for Solving the Problems'' In order to achieve the above object, the present invention includes a coin accumulation tube for accumulating and storing coins, a support body for supporting the coin accumulation tube, and a support body rotatably provided on the support body. and a coin feeding disk that places the coins in the coin accumulating cylinder on its upper surface and feeds the coins one by one to a discharge position, and a driving means that rotationally drives the coin feeding disk in its circumferential direction, and a cylindrical tube that forms a space for dropping coins between a hopper section for storing coins and a coin feeding disk, which is integrally provided with the hopper section on the discharge port side of the hopper section. A push-out plate is provided at a position facing the coin-feeding disc of the main cylinder part to press a coin dropped into the coin-dropping space toward the coin-feeding disc. A resilient member is provided between the extrusion plate and the main cylinder portion for biasing the extrusion plate toward the coin feeding disk, and further, the extrusion plate is movable in the direction of the coin feeding disk. A flange portion facing the feeding disk and extending along the circumferential direction of the coin feeding disk and formed in a horseshoe shape; The guide plate part is configured to be inserted into the discharge port and extend toward the discharge port.

"Operation" According to the coin dispensing device having such a configuration, the coins stored in the hopper section of the coin accumulating tube are dropped into the coin dropping space of the main cylinder section through the outlet of the hopper section, and are dropped therein into the coin dropping space of the main cylinder section. The coins are scooped up one by one by the coin feeding disk, but if a large number of coins enter the coin dropping space, the pushing plate is pushed up against the biasing force of the elastic member and the coins are dropped. Since the space is expanded, coins will not get caught or jammed between the extrusion plate and the coin feeding disk.

Moreover, in the above method, the coin tries to expand the coin dropping space by pushing up only the extrusion plate attached to the main cylinder part, so the response of the extrusion plate is good, and the hopper is pushed up by the action of this extrusion plate. Since there is no need to make the hopper part a movable structure, it is possible to increase the size of the hopper part. In addition, in the present invention, the guide plate part integrally provided on the inner peripheral side of the flange part of the extrusion plate is inserted with its tip facing the discharge port of the hopper part, so that the extrusion plate is dropped into the drop space. When the coins are pushed out against the biasing force of the resilient member, the coins accumulated at the discharge port of the hopper section are poked and agitated by the tip of the guide plate section.

"Embodiments" Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, the same reference numerals are given to the same components as those of the coin dispensing device shown in FIGS. 9 and 10 to simplify the description.

Figures 1 to 7 show an embodiment of the present invention, and the coin dispensing device shown here also basically has the following features:
As in the conventional case, the electric motor M rotates the coin feeding disk 1 provided in the main body 2, and the coins C scooped up by the coin feeding disk 1 are delivered to the coins through the ejection guide member 4a. The basic configuration is such that the coins are pushed out one by one from the outlet at the end of the passage through the passage 4 while being fed out one by one to the passage 4.

However, the main feature of the device according to the present invention is that instead of the coin accumulating tube 3 shown in FIG. 10, a coin accumulating tube 10 having a structure as shown in FIG. 3 is attached to the support body 2a. It is.

Hereinafter, this coin accumulating tube 10 will be specifically explained. This coin accumulating tube 10 includes a hopper section 11 for storing coins C, and a hopper section 11 provided integrally with the hopper section 11 on the discharge port side of this hopper section 11. The main cylinder part 12 forms a space for dropping coins C between the main cylinder part 12 and the coin feeding disk 1, and a space for dropping coins C is provided at a position of the main cylinder part 12 facing the coin feeding disk 1. Pushing plate 13 that pushes the coin C dropped into the space toward the coin feeding disk 1
is provided to be movable in the axial direction of the coin feeding disk 1, and between the pushing plate 13 and the main cylinder part 12 is a resilient member ( In the example shown, the coil spring) 14
is provided.

In the illustrated example, the hopper portion 11 is formed into a square tube shape whose diameter increases upward.
At its lower part, there is a discharge port 11 that communicates with the inside of the main cylinder part 12.
a is formed, and on the inner surface of the hopper part 11 facing the discharge port 11a, a partition plate 15 whose lower end protrudes from the discharge port 11a is swingably suspended via a pin 16 (a third (see Figures and Figure 4).

On the other hand, the main cylindrical portion 12 is formed into a cylindrical shape that surrounds the coin feeding disk 1 and has a notch on the top surface, and in the illustrated example, a top plate 12a continuous from the hopper portion 11, It is composed of an outer circumferential wall 12b extending from the periphery of the top plate 12a, and a flange portion 12c provided at the tip end face of the outer circumferential wall 12b and screwed to the support body 2a.

The push-out plate 13 movably disposed within the main cylinder portion 12 has a horseshoe-shaped flange portion 13a facing the coin feeding disk 1, and a flange portion 13a facing the coin feeding disk 1.
Mainly composed of a guide plate part 13b provided on the inner peripheral side of the hopper part 11 and extending along the discharge port 11a of the hopper part 11, and end plate parts 13c provided at both ends of the flange part 13a and the guide plate part 13b. (See Figure 5).

Further, a mounting pin 17 is protruded from the back surface of the flange portion 13a and is inserted into the through hole 12d of the top plate 12a of the main cylinder portion 12, and is prevented from coming off by a stopper on the outer surface of the top plate 12a. It's becoming like that. The length of this mounting pin 17 is set to allow movement of the extrusion plate 13 in the axial direction. It is now being inserted.

In addition, to supplement the explanation of the illustrated example device with reference to FIG. 1 and FIG. First and second guide plates 20 and 21 for regulating the movement of coins C are arranged in parallel in the extrusion direction of coins C via a mounting member 22 by means described later.

The first guide plate 20 is mainly composed of a mounting portion 20a that is attached to the mounting member 22, and a regulating plate portion 20b that is integrated with the mounting portion 20a. Coin C
It is attached so that it can move freely along the extrusion direction of the coin C and is biased toward the front side by a coil spring 23, and is attached so that its movement in the thickness direction of the coin C is restricted by a spring 24.

The mounting portion 20a is formed in a U-shape so as to fit on the outer surface of the mounting member 22, and
A long mounting hole 20c extending in the extrusion direction of the coin C is formed in the mounting portion 20a.
A locking hole 20d for locking the coil spring 23 is provided at the end of a.

On the other hand, a curved part 20e corresponding to the shape of the outer circumferential surface of the coin C is formed at a position facing the pushing side of the coin C of the regulating plate part 20b, which reduces the resistance to the pushing out of the coin C. Care has been taken to prevent it from getting caught in this part.

Note that the first guide plate 2 configured in this way
As shown in FIG. 2, the coin C is connected and fixed to a mounting member 22 by a screw 25 with a spring 24 interposed therebetween, and the movement of the coin C in the thickness direction is restricted by the spring 24. It can be attached.

Next, explaining the second guide plate 21, this guide plate 21 basically has a mounting part 21a attached to the mounting member 22, and a mounting part 21a, like the first guide plate 20. It is mainly composed of an integral regulating plate portion 21b.

However, in the case of this second guide plate 21,
In the case of the embodiment, the spring 2 is simply attached to the mounting member 22.
The coins C are connected and fixed by screws 25 with the coin C interposed therebetween, and the coins C are attached in a state in which movement in the thickness direction is restricted by a spring 24.

A curved portion 21c corresponding to the shape of the outer peripheral surface of the coin C is formed on the side of the regulating plate portion 21b of the second guide plate 21 facing the first guide plate 20, and a curved portion 21c corresponding to the shape of the outer peripheral surface of the coin C is formed. Care has been taken to reduce the resistance so that the coin C does not get caught in this part.

Note that the first and second guide plates 20, 2
1 to the supporting body 2a of the main body part 2 is fixed to the guide rail 4b erected on the supporting body 2a by screwing or other means. 20 along the extrusion direction of the coin C, and a contact plate 22b in which the attachment part 22a to which the second guide plate 21 is attached abuts against the guide rail 4b.
(See Figure 2).

Next, the operation of this embodiment configured as above will be explained. The coins C thrown into the coin accumulating cylinder 10 pass through the outlet 11a of the hopper part 11 and enter the coin dropping space of the main cylinder part 12. At this point, the coins C are scooped up one by one by the coin feeding disk 1. However, when a large number of coins C enter the coin dropping space, the coins C move from the extrusion plate 13 to the resilient member 14. Coin C is pushed up against the urging force of
There is no possibility that the coins will get caught or jammed between the extrusion plate 13 and the coin feeding disk 1.

Moreover, in the above, the coin C is inserted into the extrusion plate 13 attached to the main cylinder part 12, as shown in FIG.
Since the pusher plate 13 tries to push up the chisel and expand the coin dropping space, the pusher plate 13 has good responsiveness.
Therefore, if the coin C caught between the extrusion plate 13 and the coin feeding disk 1 is scooped up, the extrusion plate 13 will immediately return to its original position, and the coin C will not be bitten. There are some advantages.

In addition, in the embodiment, the action of the extrusion plate 13 eliminates the need for the hopper section 11 to have a movable structure, so the hopper section 11 can be made larger, and the capacity of the coin accumulation cylinder 10 can be increased. I can do it.

Further, according to the embodiment, since the partition plate 15 provided in the hopper part 11 comes into contact with the coin C rotating in the circumferential direction as the coin feeding disk 1 rotates, the coin C
There is also the advantage that the liquid is stirred well in this area, and there is no chance of it getting caught in the discharge port 11a.

Note that the coin feeding passage 4 is controlled by the coin feeding disk 1.
The coins C that have been sent upward are pushed out one by one through the gap between the passage 4 and the first and second guide plates 20 and 21, and are ejected from the outlet at the tip of the passage. Then, turn on count switch 5.

In the illustrated example, the deformed coin C can be removed on the passage 4 by the action of the first and second guide plates 20, 21, so that it is possible to remove the deformed coin C on the passage 4 without causing inconveniences such as counting errors. There are advantages.

Moreover, FIG. 8 shows an example in which the mounting structure of the coin accumulating cylinder 10 is modified.
A coil spring 27 is interposed between the coil spring 27 and the coil spring 27 to hold the entire stacking tube in a biased state, thereby making the stacking tube 10 swingable and further preventing the coins C from clogging. It is something.

"Effects of the Invention" As explained above, the present invention provides the following excellent effects.

(a) A coin accumulating tube for accumulating and accommodating coins is provided between a hopper section for storing coins, a coin dropping space provided integrally with the hopper section on the discharge port side of the hopper section, and a coin feeding disk. and a cylindrical main cylinder part to form a coin, and a push-out plate is provided at a position facing the coin feeding disk of the main cylinder part to press the coin dropped into the coin dropping space toward the coin feeding disk. Since the structure is such that it is movable in the axial direction of the feeding disk, and a resilient member is provided between the pushing plate and the main cylinder portion to urge the pushing plate toward the coin feeding disk,
Due to the action of the pushing plate, the coins in the coin collecting cylinder are not clogged or caught in the collecting cylinder, and can be smoothly scooped up by the coin feeding disk.

(b) In addition, by swinging the extrusion plate, the coin dropping space is expanded, so the load acting on the coin feeding member can be reduced.
It is possible to eliminate the need to power up the electric motor.

(c) In addition, only the extrusion plate is pushed up to ensure space for coins to be dropped into.
There is no need to make the hopper section for storing coins a movable structure, and therefore, the hopper section can be made larger and maintenance can be facilitated.

(d) Also, according to the present invention, the guide plate part integrally provided on the inner peripheral side of the flange part of the extrusion plate is inserted with its tip facing the discharge port of the hopper part, so that the extrusion plate is When the coins dropped into the drop space are pushed out against the biasing force of the resilient member, the coins that accumulate at the outlet of the hopper are poked by the tip of the guide plate and agitated, so that the coins are pushed out of the outlet. There is an advantage that the coins are not pinched in the area and the coins can be reliably dropped into the coin drop space. Moreover, since the coins dropped from the discharge port toward the main cylinder part pass over the guide plate part, there is an advantage that the coins can be further agitated.

Further, in the present invention, the flange portion of the extrusion plate extends along the circumferential direction of the coin feeding disk and is formed in a horseshoe shape, and the guide plate portion is also integrally provided on the inner periphery of the horseshoe-shaped flange portion. Therefore, the above-mentioned stirring action by the guide plate portion can be exerted over substantially the entire circumference of the discharge port, and there is also an effect that clogging of coins can be reliably prevented.
