Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hopper type coin dispensing machine that is disposed inside a slot machine, a money changer, a vending machine, etc., and is used to dispense a required number of coins (including game medals).

As a conventional hopper type coin dispensing machine, there is one shown in FIGS. 1 and 2. This includes a perforated disk c having a plurality of holes b into which coins a are placed in the hopper, and a vane that conveys the coin a taken in through the hole b of the perforated disk c by means of a blade d that abuts on the side surface of the perforated disk c. A rotor e is rotated on a hanging plate f, and the coin a conveyed by the blade d is sent out to the outside from a coin outlet h provided in the housing plate f.

In this conventional example, the bladed rotor e is formed by fixing a blade body j having a plurality of blades d on a circular carrier i having an annular hole g, and a portion divided by each blade d is In each case, coin a is placed on the disk i.
The coin a is placed on top of the coin a and is conveyed as the bladed rotor e rotates. Further, the housing plate f is provided with a fixing pin k that protrudes onto the disk i through the annular hole g, thereby preventing the coin a carried by the blade d from advancing. This is guided toward the coin outlet h. Incidentally, a recess l is provided on the back surface of each blade d to avoid interference with the fixing pin k.

Since the above-mentioned conventional example has the above-mentioned configuration, the width of the fixing pin k is restricted by the width of the annular hole g and the recess l, so that it cannot be secured sufficiently. As a result, it is difficult to smoothly guide the coin a to the coin outlet h, and this defect becomes particularly noticeable when the bladed rotor e is rotated at high speed. Furthermore, since the fixing pin k is fixed to the housing plate f, there is a risk that the coin a will be pushed by the blade d and get stuck between the top surface of the fixing pin k and the perforated disk c. , perforated disk c
As a result, a brake may be applied to the rotation of the bladed rotor e, and the apparatus may stop. Furthermore, since there are restrictions on the width, placement position, etc. of the fixing pin k, it is advantageous for coins a of a predetermined diameter, but it is not possible to perform the coin dispensing operation smoothly for coins a of other diameters. There's a problem.

The present invention aims to eliminate the drawbacks of the above-mentioned conventional examples, and as exemplified in the embodiments shown in FIGS. 3 and a bladed rotor 5 that transports the coin a taken in through the hole 2 of the perforated disk 3 in the rotational direction by the blades 4 in contact with this side surface, are rotated on the housing plate 6, and the blades 4 are rotated onto the housing plate 6. In a hopper-type coin dispensing machine configured to send out the coin a thus conveyed to the outside from a coin outlet 7 provided in the housing plate 6, a coin guide for guiding the coin a conveyed by the blade 4 is provided. A surface 8 is provided on the housing plate 6, while a rotating body 9 is supported on the housing plate 6, with its rotation center line sunk below the coin guide surface 8 and in a direction substantially perpendicular to the rotational direction of the bladed rotor 5. The rotating body 9 is provided with a guiding protrusion 10 that guides the coin a conveyed by the blade 4 toward the coin outlet 7, and the rotating body 9 is provided with a guiding protrusion 10 that guides the coin a conveyed by the blade 4 toward the coin outlet 7. The spring 11 is held in a rotational position protruding onto the guide surface 8.
When the blade 4 comes into contact with the guiding protrusion 10 and passes therethrough, the rotary body 9 rotates in the direction in which the guiding protruding part 10 retracts into the coin guide surface 8. It is characterized by being configured to do so.

The present invention will be specifically described below based on embodiments shown in the drawings.

In FIGS. 3 and 4, reference numeral 12 denotes a machine base, and a motor support plate 13 is attached to this machine base 12.
This motor support plate 13 is arranged at a predetermined inclination, and a rotary drive device 14 consisting of a motor and a speed reduction device is attached to the back surface thereof. A rotating shaft 15 of this rotary drive device 14 projects forward from a hole 16 provided in the motor support plate 13.

There are three screws 1 on the front of the motor support plate 13.
9 is used to attach the housing plate main body 6a made of synthetic resin. Legs 20 for forming a space are provided on the back side of the housing plate body 6a, so that a space is formed between the housing plate body 6a and the motor support plate 13. A counter support plate 17 is arranged in this space,
This is screwed to the back of the housing plate main body 6a. Further, the housing plate main body 6a has a circular recess 23 formed in the center, leaving the peripheral frame 22, and a circular hole 24 through which the rotating shaft 15 passes is provided in the center of the circular recess 23. Further, three plate-shaped bearings 18 located around the circular hole 24 are fixed to the circular recess 23 with screws. Furthermore, a ring body 25 made of fluorine-based synthetic resin whose surface becomes the coin guide surface 8 is screwed into the circular recess 23. The counter support plate 17, the plate-shaped bearing 18, and the ring body 25 are screwed and fixed to the housing plate main body 6a using a common screw 21. In addition, the common screw 21
As aids, there are screws 26 for attaching the counter support plate 17 to the housing plate body 6a, and bolts 2 for attaching the ring body 25 and the plate bearing 18 to the housing plate body 6a.
7 and nut 28 are used. Further, in FIG. 4, 53 houses a rotation support part 49, which will be described later.
It is also a through space through which a swinging rod 51 described later is inserted.

A coin outlet 7 is formed by cutting out the frame 22 on one side of the housing plate main body 6a. The lower side of the coin outlet 7 is constructed of a metal piece 30 with excellent wear resistance, which is removably attached to the housing plate main body 6a with screws 29. Since the metal piece 30 is arranged at a portion of the coin outlet 7 that is always in contact with the coin a, it has the effect of increasing the wear resistance of the housing plate main body 6a made of synthetic resin, and the dimensions of the metal piece 30 are carefully selected. This has the effect of being able to accommodate coins a of various diameters.

The housing plate 6 is constructed by attaching the counter support plate 17, the plate-shaped bearing 18, and the ring body 25 to the housing plate main body 6a as described above. The surface of the ring body 25 disposed within the circular recess 23 serves as a coin guide surface 8, and the bladed rotor 5 is rotatably supported by the plate bearing 18.

The bladed rotor 5 includes three blades 4 forming an arc as shown in the figure, and the ring body 25
The disc part 31 is loosely fitted into the disc part 31. Further, engagement holes 3 are provided at the center of the bladed rotor 5 and at a portion deviated from the center, respectively, to engage with the main engagement protrusions 32 and the sub-engagement protrusions 33 protruding from the end surface of the rotating shaft 15.
4 and 35, and by their engagement, the bladed rotor 5 is configured to rotate as the rotating shaft 15 rotates. Also, the blades 4 of the bladed rotor 5
A portion of the disk portion 31 that protrudes outward in the radial direction is seated on the coin guide surface 8 and slides on the coin guide surface 8.

The surface of the bladed rotor 5 is
It is covered by a perforated disk 3 which is assembled in a superimposed manner. This perforated disk 3 has a hole for taking coin a inside the hopper 1.
It has 2 holes. This hole 2 is formed to have a slightly larger diameter than the coin a. Further, at the center of the perforated disk 3 and at a portion offset from the center, there are provided a main engagement protrusion 32 of the rotating shaft 15 and a sub-engagement protrusion 36 protruding from the surface of the bladed rotor 5.
Engagement holes 37 and 38 are provided to engage with each other, and the perforated disk 3 is configured to rotate with the rotation of the bladed rotor 5 and, in turn, the rotating shaft 15 by their engagement. . Note that 39 is a protrusion provided on the surface of the perforated disk 3 for stirring coins.

The perforated disk 3 and the bladed rotor 5 are loosely fitted into the circular recess 23 of the housing plate 6, and are rotationally driven by the rotary drive device 14 to rotate clockwise in the figure.

The hopper 1 that accommodates a large number of coins a has a circular hole 41 for allowing the perforated disk 3 to face into the coin accommodating portion 40, and is attached to the housing plate 6 with four screws 42. There is. The four screws 42 are specifically attached to the heads of the screws 19 for attaching the housing plate body 6a to the motor support plate 13 and the screws 26 for attaching the counter support plate 17 to the housing plate body 6a. It is screwed into the screw hole formed.

The counter support plate 17 is provided with a counter 43 that moves up and down each time the coin a passes through the coin outlet 7, as shown in detail in FIGS. 5 and 6. This counter 43 is a tension spring 46
When the coin a comes into contact with the contact roller 44 provided on the counter 43 and pushes it up, the counter 43 moves upward against the tension spring 46. It is constructed as follows (see Figure 5). Also, the photocoupler 4 has the upper movement of the counter 43 attached to the counter support plate 17.
5, the number of coins passing through the coin outlet 7 is counted.

The ring body 25 supports a rotating body 9 that guides the coin a conveyed by the blade 4 to the coin outlet 7. As shown in FIGS. 5 to 8, this rotating body 9 is formed by cutting one side of a cylindrical body with a plane in the axial direction, and cutting the end of this plane part 47 into a V-shaped groove.
The cut surface 48 on the side connected to the circumferential surface of the V-shaped groove is formed in the radial direction of the rotating body 9.

The ring body 25 is provided with a support portion 49 that rotatably supports the rotating body 9. The back side of this support part 49 is open, and the inner surface 50 of this support part 49 is formed into a curved surface along the rotating body 9.

A swinging rod 51 is fixed to the rotating body 9, and the swinging rod 51 projects toward the back of the ring body 25 through a space on the back side of the support portion 49. The other end of the tension spring 11, one end of which is fixed to the counter support plate 17, is fixed to the tip of the swinging rod 51.

The rotating body 9 is disposed in a direction substantially perpendicular to the rotational direction of the bladed rotor 5, and its rotation center line is at a position sunk below the coin guide surface 8. When the rotary body 9 is in the position shown in FIG. It stands perpendicular to the guide surface 8. Further, the tension spring 11 urges the rotating body 9 in a direction that causes the guiding protrusion 10 to protrude above the coin guide surface 8. In the rotating position shown in FIG. By abutting the position regulating part 52 of the support part 49,
Further rotation of the rotating body 9 is prevented. The coin a conveyed by the blade 4 is
When the coin collides with the guide protrusion 10, the direction changes and the coin is guided toward the coin outlet 7. However, since it is not preferable for the guide protrusion 10 to rotate due to the collision force at this time, the tension spring The biasing force 11 needs to be selected so as to overcome the collision force.

On the other hand, as shown in FIG. 8, when the blade 4 comes into contact with the guide protrusion 10 and passes there, a large force is applied to the rotating body 9 to forcibly rotate it in the counterclockwise direction in the figure. 9 is the tension spring 11
The guiding protrusion 10 sinks below the coin guiding surface 8. At this time, the flat portion 47 of the rotating body 9 becomes substantially the same as the coin guide surface 8. Incidentally, when the lower surface of the blade 4 is cut, the passage of the blade 4 can be allowed even if the guiding protrusion 10 of the rotating body 9 does not sink below the coin guide surface 8.

Next, the operation of the hopper type coin dispensing machine having the above configuration will be explained. As the rotation shaft 15 of the rotation drive device 14 rotates, the bladed rotor 5 and the perforated disk 3 rotate clockwise in the figure. Due to this rotation, the coin a in the coin storage section 40 of the hopper 1 is
are taken into the perforated disk 3 through the hole 2, and held one by one in the coin holding space 54 formed between each blade 4 of the bladed rotor 5.

As the bladed rotor 5 rotates, the coin a held in the coin holding space 54 is pushed by the blades 4 and conveyed on the coin guide surface 8 toward the coin outlet 7. When the coin a reaches a position where it comes into contact with the guiding protrusion 10 of the rotating body 9, the coin a changes direction and is guided toward the coin outlet 7, as shown in FIG. As shown in FIG. 5, the blade 4 is formed to draw an arc suitable for guiding the coin a toward the coin outlet 7, so that, together with the guiding protrusion 10, the blade 4 can be smoothly guided toward the coin outlet 7.
When the coin a passes through the coin outlet 7, it is counted by the counter 43 as described above.

After sending out the coin a to the coin outlet 7, the rotary body 9 is rotated so that the blade 4 contacts the guide protrusion 10 of the rotary body 9 and the guide protrusion 10 is sunk below the coin guide surface 8. Pass over this. After the blade 4 has passed, the rotating body 9 is rotated back to its original position by the tension spring 11, and its guiding protrusion 10 is guided to the coin guide surface in order to guide the next coin a to the coin outlet 7. Protrudes above 8.

The above operation is repeated three times per rotation of the rotating shaft 15, and the coin a is delivered to the coin delivery port 7 each time.

The present invention can be configured in various ways other than those shown in the above embodiments. For example, in the above embodiment, the number of holes 2 of the perforated disk 3 and the number of blades 4 of the bladed rotor 5 are three, but it is needless to say that the number is not limited to this number. It is also possible to form the ring body 25 integrally with the housing plate 6. Further, the rotating body 9 is disposed in a direction substantially perpendicular to the rotational direction of the bladed rotor 5, but the intersecting angle with the rotational direction may be considerably more than 90°,
In short, it is sufficient as long as the original function of guiding the coin a to the coin outlet 7 is not impaired. Further, the rotating body 9 may be supported around an axis. Further, the shape of the rotating body 9 is not limited to that shown in the above embodiment, and the shape of the rotating body 9 is not limited to that shown in the above embodiment.
1, a torsion spring or the like can be used instead of the tension spring.

Since the present invention has the above configuration, the following effects can be achieved.

Since the rotating body with the above configuration is used as a member for guiding the coin to the coin outlet,
The length of the guiding protrusion that guides the coin can be made necessary and sufficient to be suitable for guiding the coin, and the shape of the guiding protruding part can also be made ideal, so that the coin can be easily guided. It has the effect of smoothly and reliably guiding coins to the outlet.

The above effect is particularly noticeable when driving at high speeds.

The rotating body is rotatably supported by the housing plate at a position where the center line of rotation is sunk below the coin guide surface and in a direction substantially orthogonal to the rotational direction of the bladed rotor, so that when the blades pass, The rotation and return movement after passing the blade are smooth, and the coin guiding action can be performed reliably. In addition, even if the coin is not guided to the coin outlet and attempts to pass over the rotating body, the above-mentioned rotation of the rotating body allows the coin to pass smoothly over the rotating body. can perform an action. This makes it possible to solve the problem of coins being bitten in the conventional example.

Since the rotating body can smoothly and reliably guide coins of various diameters to the coin dispensing port, the present invention provides a highly versatile hopper type coin dispenser that can be used for coins of various diameters. We can provide equipment.
