Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention is arranged inside a slot machine, a money changer, a vending machine, etc., and is used to dispense a required number of coins (including coin-like coins such as medals). This invention relates to a hopper type coil dispensing device used for dispensing coils.

(Prior Art) A hopper type coin dispensing device currently in common use is shown in FIG. 6. In this conventional example, the coin a in the hopper is transferred to the perforated disk b.
The coin is taken into the rotor d through the coin taking-in hole c, and the coin is placed on the coin guide surface f of the inclined base e and is conveyed toward the coin delivery port by the arcuate blade g of the rotor d.

(Problems to be Solved by the Invention) According to this conventional example, as the perforated disc b swings during rotation, the distance H' between the perforated disc b and the coin guide surface f becomes constant. First, as shown in FIG. 6, an extra coin a sometimes entered the rotor d obliquely through the coin intake hole c and was bitten into it. These coins a and a exert a braking effect similar to that of driving a wedge between the perforated disk b and the coin guide surface f, often causing the device to stop, and hindering the smooth operation of the device. There was a problem of damage.

In addition, as an improvement on the above conventional example, JP-A-59
There is a prior art described in the -81784 publication. This prior art provides a coin placement surface on the rotor d,
Since the configuration is such that the coin a is conveyed toward the coin delivery port with the coin a placed on the coin placement surface, the frictional resistance exerted on the coin a from the coin guide surface f in the conventional example can be reduced. It has the advantage of being able to However, even in this prior art, the perforated disk b and rotor d are coupled with play that allows for relative rotation.
During these rotations, the distance between the perforated disk b and the coin placement surface of the rotor d is not constant, and as in the case shown in Fig. 6, there is a problem that a braking action occurs due to the extra coin a biting into it. It was hot.

(Means for Solving the Problem) The present invention improves the above prior art and provides a hopper type coin dispensing device as follows in order to eliminate any room for excess coins to be taken into the rotor from the coin intake hole. It is characterized by having been configured.

That is, the present invention includes a rotor that rotates on a base and is equipped with a coin placement surface and an arcuate blade for transporting coins, a coin intake hole for taking coins in a hopper into the rotor, and an agitator protrusion for stirring coins. a perforated disk, and the perforated disk is fixed to the rotor using a fixing means so that a constant distance is maintained between the rotor and the coin placement surface. do.

(Function) According to the above structure, the perforated disk is integrally mounted on the rotor, and the distance between the perforated disk and the coin placement surface of the rotor is always kept constant even during rotation. (The spacing does not change even when an external force is applied), so it is possible to reliably prevent extra coins from diagonally entering the rotor through the coin intake hole and getting wedged in the spacing, as in conventional examples and prior art. As a result, smooth operation of the device can be maintained at all times.

(Embodiment) In the illustrated embodiment, 10 is a machine base, 11 is an inclined base, and 12 is a drive mechanism, which includes a motor 12a and a speed reduction device 12b.

As shown in FIG. 2, the inclined base 11 is arranged inclined with respect to the vertical plane, and has a circular recess 13 for rotatably supporting the rotor 3, and a coin outlet 5 formed on one side thereof. ing. 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. As shown in FIG. 3, this coin inductor 4 is composed of a retractable element 15 and a spring 16 that biases the retractable element upward.
5 protrudes above the guide surface 14 and functions to guide the coin a conveyed by the rotor 3 toward the coin outlet 5.

The coin outlet 5 is formed by carving out the side of the inclined base 11, and is covered with a cover plate 40. Further, a guide piece 41 for guiding the coin a is fixed to the lower edge of the coin outlet 5.

The rotor 3 is rotatably fitted into the circular recess 13 with play. As shown in FIG. 2, the rotor 3 consists 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. and the disk portion 17
is loosely fitted into the circular recess 13 and the guide ring 14, so that the rotor 3 is rotatably supported by the inclined base 11.
Further, the upper surface of the disk portion 17 serves as a coin placement surface 17a on which the coin a is placed, while the upper surface of the blade portion 1
8, five arcuate blades 2 are formed, 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 each arcuate blade 2 to avoid interference with the protruding element 15.

A perforated disk 20 is fixed to the upper surface of the rotor 3 with screws 38. For this purpose, a screw insertion hole 51 is provided in the rotor 3, and a screw hole 52 is provided in the perforated disk 20. Further, when the perforated disk 20 is integrally mounted on the rotor 3, it is necessary to maintain a predetermined distance H between the perforated disk 20 and the coin mounting surface 17a of the rotor 3. Specifically, the flatness of the joint surfaces of the perforated disk 20 and the rotor 3 and their perpendicularity to the drive shaft 23 described below must be formed with high precision. Note that the above distance H is based on the thickness of coin a.
When it is 1.5 mm, it is preferable to set it to 2 mm, and it is preferable to set the error within ±0.05 mm. The perforated disk 20 has five coin intake holes 21 communicating with the coin holding space Q, and has the function of taking the coin a in 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 the rotor 3 and the perforated disk 20, but in order to connect the two, the rotor 3 and the perforated disk 20 are
Engagement holes 24, 24a, which engage with the drive shaft 23 of No. 2;
50, 50a are provided.

The hopper 1 has a coin storage section 25 and a flange section 2.

In the vicinity of the coin inductor 4, as shown in FIG. 4, there is disposed a separator 6, which has a swing plate 7 supporting a separate roller 8 and an auxiliary roller 28. The swing plate 7 has a vertically long pivot hole 29,
This is the pivot 30 in a fixed state provided on the inclined base 11
is fitted. Further, the swing plate 7 is biased by a tension spring 9 so as to be attracted toward the rotor 3, and as a result, the separate roller 8 and the auxiliary roller 28 are moved toward the outer peripheral edge 3a of the rotor 3.
is in contact with. The position thus positioned, that is, the position shown in FIG.
However, as described above, since the pivot hole 29 of the swing plate 7 is formed as a vertically elongated hole, the swing plate 7 can swing relative to the pivot shaft 30 and can move in a straight line. Therefore, the separate roller 8 can retreat from the reference position P to the side opposite to the rotor 3, and the oscillating plate 7
It can move left and right as the oscillates.

In this embodiment, when the separate roller 8 is at the reference position P, as shown in FIG. configured to match. 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 attached to the cover plate 40.
It is arranged so as to cross a counter sensor 34 such as a photocoupler attached to the inclined base 11 via the counter. In this embodiment, the separate roller 8 is supported by a shaft 35 that pivots a counter lever 31. The counter lever 31 is moved to the fourth position by a return spring 36.
The coin a is held at the position shown by the solid line in the figure, but each time the coin a passes through the coin outlet 5, it swings as shown by the imaginary line, and the passage of the coin a is detected by the sensor 34. , the number of passing coins a is counted.

Next, the operation of the coin dispensing device having the above configuration will be explained.

The rotor 3 and the perforated disk 20 are the drive mechanism 1
When rotated clockwise in the figure by 2,
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 placed on the coin placement surface 17a of the rotor 3 and is pushed forward by the arcuate blades 2 and conveyed toward the coin guide 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. When coin a passes through coin outlet 5,
As described above, the number of passing sheets is counted by swinging the counter lever 31.

Further, the coin a which is not properly guided by the inductor 4 is guided to the coin outlet 5 by the action of the separator 6.

Based on this idea, the present invention can be configured in various embodiments in addition to those shown in the above embodiments.

For example, as in the embodiment shown in FIG. 5, a perforated disk 20 can be welded onto the rotor 3 so that the two can be integrated with a predetermined distance H maintained therebetween.

(Effects of the Invention) The present invention has an agitator protrusion for stirring coins on the perforated disc, and allows coins to be taken into the coin intake hole of the perforated disc relatively smoothly. It has a configuration in which the coin is fixed on the rotor using a fixing means so that a certain distance is maintained between it and the coin placement surface, and the excess coin enters diagonally into the rotor through the coin intake hole. Since it is possible to reliably prevent the coin from getting stuck in the space between the empty disk and the coin placement surface, it is possible to maintain the smooth operation of the device at all times.
