Detailed Description of the Invention (Industrial Application Field) The present invention is arranged inside a slot machine, money exchange machine, vending machine, etc., and a required number of coins (including coin analogues such as medals) are inserted into the machine. This invention relates to a hopper type coin dispensing device used for dispensing coins.

(Prior art and its problems) A conventional hopper type coin dispensing device is disclosed in Japanese Patent Application Laid-Open No. 59-8
As an example is shown in Publication No. 1784, the coin inductor for transferring the coins conveyed by the rotor to the coin dispensing port had a fixed structure, which caused the problem that coins were likely to get caught. there were.

(Purpose of the invention) The present invention aims to solve the problems of the conventional example.

(Structure of the Invention) The present invention takes a coin a in a hopper 1 onto a rotor 3 equipped with a plurality of arcuate blades 2, pushes the coin a with the arcuate blades 2, and transports the coin a toward a coin inductor 4. This hopper type coin dispensing device is configured to transfer coins a from the rotor 3 to the coin outlet 5 by means of a coin inductor 4, and has the following characteristic configuration.

The first feature is that the coin inductor 4 has a movable structure to prevent the coin a from getting caught.

The second feature is that the coin a, which has not been successfully guided by the coin inductor 4, can be guided toward the coin outlet 5 by a separator 6 placed near the coin inductor 4. However, although the coin a may be separated by the separator 6 in the direction of escape, in either case, the coin a is prevented from being caught.

The third feature is that the separator 6 is constructed as follows. That is, the separator 6 is constructed by supporting a separate roller 8 on a swing plate 7, and is biased by a spring 9 so as to draw the swing plate 7 toward the rotor 3 so that the separate roller 8 is moved near the outer periphery of the rotor 3. In addition to being positioned at the reference position P, the swing plate 7 is arranged to be swingable and movable in a straight line, and the separate roller 8 is moved to the reference position P.
It is configured so that it can retreat from the rotor 3 toward the side opposite to the rotor 3 and can also move left and right in accordance with the vibration of the swing plate 7.

(Example) In the illustrated example, 10 is a machine, 1) is a base, 1
A drive mechanism 2 includes a motor 12a and a speed reduction device 12b.

The base 1) is arranged inclined with respect to the vertical plane as shown in FIG. 2, and has a circular recess 13 for rotatably supporting the rotor 3, and a coin outlet 5 formed on the negative side thereof.
It is equipped with A guide ring 14 is provided within the circular recess 13 and concentric therewith, and a coin guide 4 that retracts from the guide surface 14a of the guide ring 14 is disposed at a predetermined location on the guide ring 14. This coin inductor 4 is the third
As shown in the figure, it is composed of a retractable element 15 and a spring 16 that urges it upward. Normally, the retractable element 15 protrudes above the guide surface 14a, and the coin a conveyed by the rotor 3 is sent to the coin outlet. It acts to guide people towards 5.

The coin outlet 5 is formed between the sides of the base 1) and covered with a cover plate 40. Also, coin outlet 5
A guide piece 41 for guiding the coin a is fixed to the lower edge of the coin a.

The rotor 3 is rotatably fitted into the circular recess 13 with play. As shown in FIG. 2, the rotor 3 is composed of a disk portion 17 and a blade portion 18, and the disk portion 17 is provided with a ring hole 19 that loosely fits into the guide ring 14. By loosely fitting the disk portion 17 into the circular recess 13 and the guide ring 14, the rotor 3 is rotatably supported by the base plate 1). On the other hand,
Five arcuate blades 2 are formed in the blade portion 18, and a coin holding space Q is formed between these arcuate blades 2.

Further, as shown in FIG. 3, a groove 37 is formed on the back surface of the six-arc shaped blade 2 to avoid interference with the projecting element 15.

On the upper surface of the rotor 3, a perforated disk 20 is attached with a screw 38.
is fixed by. This perforated disk 20 has five coin intake holes 21 communicating with the coin holding space Q, and has the function of taking coins a from the hopper 1 into the coin holding space Q of the rotor 3 from each coin intake hole 21. do. 22 is an agitator projection for stirring coins.

The rotor 3 rotates together with the perforated disk 20 in the clockwise direction in the figure. It is the drive mechanism 12 that rotationally drives this rotor 3, but due to the connection between the two,
The rotor 3 is provided with an engagement hole 24.24a that engages with the drive shaft 23 of the drive mechanism 12.

The homper 1 has a coin accommodating portion 25 and a flange portion 26. 42 is a retaining hole provided in the flange portion 26, 43 is an engagement pin provided on the base 1), and 44 is a positioning pin provided on the base 1).Using these, the hopper 1 is attached to the base 1). It can be attached removably.

Near the coin inductor 4, as shown in FIGS. 4 and 5, a separate roller 8 and an auxiliary roller 2 are mounted on a swing plate 7.
A separator 6 supported by a separator 8 is disposed. The rocking plate 7 has a vertically elongated pivot hole 29, which is fitted into a fixed pivot shaft 30 provided on the base plate 1). Further, the swing plate 7 is urged to be drawn toward the rotor 3 by a tension spring 9, and as a result, the separate roller 8 and the auxiliary roller 28 are moved toward the outer peripheral edge 3 of the rotor 3.
is in contact with a. The position determined in this manner, that is, the position shown in FIGS. 4 and 5 is the reference position P of the separator 6 and, in turn, the separation roller 8. Since the hole 29 is formed as a vertically long hole, the swing plate 7 is
can swing and move in a straight line. Therefore, the separate roller 8 can retreat from the reference position P toward the side opposite to the rotor 3, and can also move left and right as the rocking plate 7 swings.

In this embodiment, when the separate roller 8 is at the reference position P, as shown in FIGS. 4 and 5, a line N connecting the center S of the rotor 3 and the pivot shaft 30 and the center of the pivot hole 29 The structure is such that the line M substantially coincides with the line M. At this time, the separate roller 8 is located on the left side of the line N, and the auxiliary roller 28 is located on the right side.

A counter lever 31 is pivotally supported on the swing plate 7, and a counter roller 32 is attached to one end of the counter lever 31, while the other end 33 is used for a counter such as a photocoupler attached to the base plate 1) via the cover plate 40. sensor 3
They are arranged across 4. In this embodiment, the separate roller 8 is supported by a shaft 35 that pivots a counter lever 31. The counter lever 3
1 is held by the return spring 36 at the position shown by the solid line in FIG. As a result of the passage of coin a being detected, the number of passing coins a is counted. - Next, the operation of the coin dispensing device having the above configuration will be explained.

When the rotor 3 and the perforated disk 20 are rotated clockwise in the figure by the drive mechanism 12, the coin a in the hopper 1 is taken into the coin holding space Q of the rotor 3 through the coin taking hole 21.

The coin a in the coin holding space Q is held by the arcuate blade 2.
The coin is pushed forward and conveyed toward the coin inductor 4.

As shown in FIG. 4, when the coin a comes into contact with the coin inductor 4, its direction is changed and the coin a is guided toward the coin outlet 5. As described above, when the coin a passes through the coin outlet 5, the counter lever 31 is swung to count the number of coins passed.

The inductor 4 has a movable structure, and in this embodiment, the retractor 15 is urged upward by a spring 16 and moves up and down, so that the coin a carried by the rotor 3 Of these coins, coin a which assumes an abnormal posture (the probability thereof is low) sinks the recessed element 15 below the guide surface 14a of the guide ring 14 and does not pass over the coin guide 4 as it is. Also, the coin holding space Q
If there is no coin a inside, the coin a that flies in from the coin receiving hole 21 may be in a similar state. In the conventional example, there was a problem in which the coin a was pressed against the fixed coin inductor, but in the present invention, since the coin inductor 4 has a movable structure, this problem can be solved. It can be done.

FIG. 5 shows a state in which the coin a, which has not been guided toward the coin outlet 5 by the coin inductor 4, comes into contact with the separation roller 8 of the separator 6. Most of the coins a in this state are guided to the coin delivery port 5 by the action of the separation roller 8, as shown in FIG. In this embodiment, the separate roller 8 contacts the outer peripheral edge 3a of the rotor 3 and rotates at high speed, so that the coin a can be guided to the coin outlet 5 more smoothly.

In Fig. 6, although the probability is extremely low, the center T of the coin a is on the line connecting the center of curvature ■ of the arcuate blade 2 and the center W of the separate roller 8, and there is a tension between the three parties.
shows a case where this is a problem. In the case of the present invention, as shown in FIG.
is retreated toward the side opposite to the rotor 3, and as the swing plate 7 swings in the direction of the arrow, the separate roller 8 swings in the direction of the arrow, so that the jamming is prevented and the coin a enters the coin outlet 5. Directed towards. Further, in this embodiment, since the pivot shaft 30 is located at a position E-eccentric with respect to the line, the swing plate 7 is configured to automatically swing in the direction of the arrow in response to the pushing pressure of the coin a. As a result, most of the coins a in the state shown in FIG. 6 can be guided toward the coin outlet 5.

There are rare cases where the coin a is swung to the right from the state shown in FIG. The coin a is guided again to the coin holding space Q of the rotor 3 by the action of the auxiliary roller 28 (
(escape action), and the problem of jamming is prevented from occurring.

The present invention can be configured in various ways other than those shown in the above embodiments. For example, the coin inductor 4 may have a movable structure composed of a rotating body. Furthermore, the aspect of the separator 6 is not limited to that shown in the above embodiments,
For example, a structure without the auxiliary roller 28 may be used. Furthermore, it is also possible to configure the spring 9 that biases the rocking plate 7 with a torsion spring.

(Effects of the Invention) Since the present invention has the above-mentioned configuration, it is possible to achieve the effect of reliably solving the problem of coins getting stuck, as detailed in the description of the embodiments.
