DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a coin payout apparatus used for paying out change in a vending machine, paying out coins in a change machine, paying out coins in a game machine, and the like.

[0002]

2. Description of the Related Art Coins in a hopper are captured by holes formed in a rotating disk provided on the bottom surface of the hopper, and coins in the hopper are inserted one by one by projecting pieces on the back surface of the disk provided in relation to the holes. No. 55-4 as a coin dispensing device which is pressed and conveyed to a coin outlet.
8634, JP-B-63-36040, Jitsuho 2-1
No. 9882 is already known.

[0003] In each case, a single rotating disk is used to catch coins in the hopper, and in order to perform an efficient payout operation, a hole for catching coins is formed on the disk surface. It is necessary to arrange a large number of concentric circles, and consequently, the arrangement positions of the holes are made closer, or
It is necessary to increase the diameter of the disk itself and make a large number of holes in the circumferential direction. By the way, Japanese Patent Publication 55-48634
The disc of No. 4 has four holes, and the disc of JP-B-63-36040 has five holes.

[0004] However, if the positions of the holes are brought close to each other, a sufficient spot facing cannot be formed on the edge of the hole on the front side of the disc, and the edge of the hole is caught by the coins stored in the hopper. There is. If the disk is rotated in this state, the motor may be overloaded, especially when a large load is applied due to a large number of coins remaining in the hopper. In addition, when a large number of holes are provided by increasing the circumferential length of the disk by increasing the diameter of the disk itself, the substantial stopping resistance given to the disk by the coin in the hopper is increased by the radius. It increases in proportion, and again the motor is overloaded, which leads to an increase in the size of the device.

Conversely, even if a small number of holes are provided in a small-diameter disk to improve the payout efficiency by increasing the rotation speed of the disk, a coin is flipped at the edge of the hole and the disk runs idle. Since the phenomenon occurs, the coin capture rate decreases, and sufficient payout efficiency cannot be obtained. In some cases, a bridge occurs near the disk, and it is sometimes difficult to capture the coin by the disk.

In this type of coin payout apparatus, it is necessary to prevent the coins from remaining and to surely guide the coins in the hopper to the position where the disk is disposed. Alternatively, a method of inclining the bottom surface of the hopper toward the position where the disk is disposed is generally used (see Japanese Patent Publication No. 55-48634, Japanese Patent Publication No. 63-36040, and Japanese Utility Model Publication No. 58-19646). According to such a configuration, the probability of occurrence of a bridge is further increased. Note that a bridge is a phenomenon in which a large number of coins at the bottom of a hopper are intricately entangled to form a lump, preventing the normal flow of coins.A coin payout device provided with an optical empty sensor at the bottom of the hopper. In this case, the hollowing of the bottom of the hopper by the bridge may be erroneously recognized as no coin to be paid.

Therefore, as a means for preventing the occurrence of a bridge, a coin dispensing apparatus in which a stirring bar in a spiral state is erected at the center of a disk or a feed blade rotating in conjunction with the disk and rotated. Is real fair 2-1
No. 9882, these stir bars only rotate at fixed positions about their axes, and a sufficient stirring effect cannot be expected.

[0008]

SUMMARY OF THE INVENTION An object of the present invention is to eliminate the drawbacks of the prior art and achieve the required coin payout efficiency without imposing an excessive load on a motor serving as a disk driving means. Another object of the present invention is to provide a coin payout device capable of preventing occurrence of a bridge that hinders payout.

[0009]

According to the present invention, there is provided a coin dispensing apparatus in which a hopper for storing coins is provided on a base plate surface, and the first hopper which is driven by driving means and rotated synchronously on the bottom surface of the hopper. , A second disk is mounted adjacent to and spaced from the base plate surface by a distance corresponding to the thickness of the coin, and the first and second disks are
A through hole through which the coin passes, and a protruding piece that presses and conveys the coin dropped through the through hole onto the base plate surface are provided corresponding to the through hole, and the second disk has a first hole. A protruding piece for pressing and conveying the coin conveyed by the disc;
A guide piece for guiding the coin carried by the second disc to the area of the second disc, and a guide piece for guiding the coin carried by the second disc to the coin outlet. The above objective has been achieved.

Further, the drive mechanism is simplified by synchronously rotating the first and second disks by means of a motor for rotating any one of the disks and teeth formed on the outer periphery of each disk and meshing with each other. The size of the disk was reduced, and a projection for stirring was provided on the upper surface of each disk at a distance from the center of rotation of the disk to prevent the occurrence of a bridge.

Further, by forming a gentle counterbore extending in the circumferential direction on the upper surface of the disk in the through hole of each disk, the coin is prevented from being caught and the motor is prevented from being overloaded.

[0012]

The first and second disks disposed on the bottom surface of the hopper are synchronously rotated by the driving means, and the coins in the hopper are captured in the through holes of the first and second disks. The coin that has dropped onto the base plate surface through the through hole of the first disc is pressed and conveyed by the projecting piece of the first disc, and is guided to the area of the second disc by a guide piece that guides the coin in cooperation with the projecting piece. Be guided. The coin that has dropped onto the base plate surface through the through hole of the second disk is pressed and conveyed by the projecting piece of the second disk, and the coin guided by the first disk to the area of the second disk is: Apart from this, it is pressed and conveyed by a projecting piece provided on the second disk. The coin conveyed by the second disk is guided to the coin outlet by a guide piece for guiding the coin in cooperation with each projecting piece provided on the second disk, and is paid out from the coin outlet.

Since the diameter of the disk itself is increased to increase the circumferential length of the disk, instead of providing a large number of through holes, the through holes are distributed and provided on a plurality of disks. The radius becomes smaller,
As a result, the substantial stopping resistance applied to the disk by the contact of the coin in the hopper is reduced, and the load on the motor is reduced. Then, since the coins to be paid out are captured at the arrangement positions of the first and second disks provided separately, that is, the entire bottom surface of the hopper, the diameter of the hopper is reduced or the disk arrangement is performed. It is not necessary to guide the coin to the disk by tilting the bottom of the hopper toward the position, and coins are taken out evenly from each part of the hopper bottom, so that the coin storage state is less likely to be biased,
Bridges are also prevented from occurring.

Further, the first and second disks are rotated synchronously by a motor for rotating one of the disks and a tooth formed on the outer periphery of each disk and meshing with each other. No special interlocking mechanism for synchronously rotating the disk is required, and an alternative synchronous rotation mechanism is formed on the same plane as the first and second disks provided on the bottom of the hopper. It is downsized.

On the upper surfaces of the disks arranged at different positions, projections for agitation protrude from the center of rotation of the disks, and these agitation projections revolve with the rotation of the disks. By doing so, the coin is agitated over the entire bottom surface of the hopper, so that the coin storage state is less likely to be biased, and the occurrence of a bridge is more reliably prevented.

Further, the arrangement interval of the through holes in each disk is increased by disposing the through holes in a plurality of disks, and a gentle counterbore extending in the circumferential direction on the upper surface of the disk is formed for each through hole. The edge of the hole does not catch on the coins stored in the hopper, and the load on the motor is reduced more reliably.

Is fixed to the casing 7 having the inside. A slope 32 is formed on one side of the casing 7, that is, at a position corresponding to the coin outlet 29 of the base plate 4.
The coins falling from 9 are rolled and paid out to a change payout port of a vending machine, a coin payout port of a currency exchange machine, a coin payout port of a game machine, and the like.

As shown in FIG. 3A, the payout detector 8 provided on the base plate 4 facing the coin outlet 29 causes the tip bent portion 34a to extend along the surface of the cavity region 19. , Base plate 4 by pin 35
A detection lever 34 pivotally supported with respect to the light-shielding member, a light-shielding plate 33 integrally attached to the lever 34, and one end fixed to the base plate 4, and the lever is turned counterclockwise in FIG. A coil spring 36 for urging the light-receiving plate 34, a photocoupler 37 fixed on the base plate 4 so as to sandwich the light shielding plate 33, and the like. In addition,
The state shown in FIG. 3A is the initial position of the detection lever 34, that is, the inoperative position.

In FIG. 3A, as an example, the guide piece 28 of the cavity area 19 and the projecting piece 2 of the second disk 6 are shown.
The case where coins are paid out by the cooperative operation with 5a is shown.

When the second disk 6 further rotates counterclockwise from the state shown in FIG. 3A, a part of the coin held on one side by the guide piece 28 and pressed and conveyed by the protruding piece 25a is used as shown in FIG. As shown in (b), the coin protrudes from the cavity area 19 to the area of the coin outlet 29, and the end of the protruding coin presses the linear portion of the detection lever 34, and the lever 3
4 and the light shielding plate 33 rotate clockwise against the urging force of the coil spring 36, and the light shielding plate 33 is

The payout of coins is detected by detecting the moment of darkening of the light receiving element.

Until the coin passes through the coin outlet 29 and falls off, the detection lever 34 and the light shielding plate 33 rotate clockwise in accordance with the amount of protrusion of the coin pressing the detection lever 34, as described above. The payout detection timing is the moment when the light receiving element of the photocoupler 37 darkens, and other than this time, no payout signal is output. Then, the end of the coin protruding into the area of the coin outlet 29 exceeds the refraction portion, which is the portion between the straight portion of the detection lever 34 and the bent portion 34a, and most of the coin is shown in FIG. As described above, when the protruding portion protrudes from the cavity region 19 and enters the region of the coin outlet 29, the inner concave portion of the tip bent portion 34a is fitted to the end of the coin, and the detection lever 3
4 returns slightly counterclockwise by the urging force of the spring 36, and the accumulated pressure of the coil spring 36 is attenuated. The urging force of the coil spring 36 is set to a minimum necessary to return the detection lever 34 and the light shielding plate 33 in the free state (the state where the coin is not sandwiched) to the initial position. The part is the coin outlet 29
3C, the inner concave portion of the distal bent portion 34a is fitted to the end of the coin, and the accumulated pressure of the coil spring 36 is attenuated. Therefore, the coin in the state of FIG. Thus, the coin is not strongly pinched, and the coin can easily fall through the coin discharge port 29 by its own weight.

Further, as shown in FIG. 1, the hopper 2 has a hopper base 40 having two through holes 38 and 39 at the bottom, and a plurality of coins which are externally fitted to the hopper base 40 to store a large number of coins. And an extension tube 41. A dowel (not shown) protrudes from the lower surface of the hopper base 40.
And the hopper base 40 with respect to the base plate 4
Is positioned and fixed. The through holes 38 and 39 of the hopper base 40 are formed in the base plate 4 at positions corresponding to the positions of the first disk 5 and the second disk 6, and the inner diameter of the through holes 38 and 39 is equal to the first disk. 5 and slightly smaller than the outer diameter of the second disk 6. More specifically, the inner diameters of the through holes 38 and 39 are equal to or slightly smaller than the reference circles of the first disk 5 and the second disk 6 as spur gears. The coins stored in the hopper 2 and the teeth 16 of the first disk 5 and the second disk 6,
17 is prevented. The bottom of the hopper base 40 is formed with a gentle slope of a mortar centered on the through holes 38 and 39.

The bottom surface of the hopper 2 is substantially a hopper base 4
0, the first disk 5, and the second disk 6, and therefore, it can be said that the first disk 5 and the second disk 6 are mounted adjacent to the bottom surface of the hopper 2. . Extension tube 4
In the lower part of the inside of 1 or the inside of the hopper base 40, the shortage of coins is detected and the change of the vending machine is displayed,
Although an empty sensor for displaying a use prohibition of a money changer or a game machine or the like is provided, the configuration and mounting position of the empty sensor are well known and will not be particularly described.

Next, the payout operation of the coin payout apparatus 1 according to the present embodiment will be described with reference to FIGS. The coin dispensing apparatus 1 of the embodiment receives one coin dispensing instruction from a vending machine, a coin dispensing instruction from a money changing machine, or a coin dispensing instruction from a game machine, and receives one coin or game coin as money. It is the same as the conventional device in that the control device detects whether or not the payout is executed by the payout signal from the payout detector 8 and performs a series of sequence operations. The mechanical operation based on the configuration and the operation and effects associated therewith will be described.

First, when the drive of the geared motor 9 is started by an appropriate payout command, the output shaft 2 of the motor 9 is started.
The second disk 6 fixed to 2 rotates counterclockwise with reference to FIG. 4, and at the same time, the first disk 5 rotates clockwise. Among the coins stored in the hopper 2, the coins in the lower layer are separated from the first disc 5 or the second disc 5 along the mortar-shaped bottom of the hopper base 40 by the weight of the coins located in the upper layer and the weight of the coin itself. These coins are guided to the upper surface of the first disk 5.
Alternatively, it contacts and presses the surface of the second disk 6.

Therefore, the surfaces of the first disk 5 and the second disk 6 try to stop the rotation of the disks 5 and 6 by the stopping resistance provided by the coin, that is, the frictional force between the disk surface and the coin. Force acts,
A load acts on the geared motor 9. As described above, each of the disks 5, 6 is separated from the surfaces of the cavity regions 18, 19 by the thickness of the coin, and each of the disks 5, 6 itself has a constant thickness. So, in particular,
In the first disk 5, the coin is likely to be caught at the position where the through holes 10a and 10b are formed, and in the second disk 6, the coin is likely to be caught at the position where the through holes 13a and 13b are formed. It will be easier. However, mortar-shaped counterbores 11, 14 extending along the circumferential direction of the disks 5, 6 are formed on the outer peripheral portions of the through holes 10a, 10b and 13a, 13b, respectively. The blocking resistance caused by the hole edge clogging is reduced as compared to conventional disks which are closely arranged on the surface concentric circles, i.e., disks which cannot form sufficient counterbore around the hole.

The same effect can be obtained even when the diameter of the disk itself is increased and a counterbore similar to that of this embodiment is provided for each hole. For example, in order to achieve the same coin catching ability as in the present embodiment, the conventional product still requires four holes. However, since there is only one disk, the conventional product requires the four holes. Must be punched on a single disk. Here, if a sufficient counterbore is provided for each hole as in the present embodiment, the drilling position of each hole must be separated, and as a result, the diameter of the disk necessarily increases. . Assuming that the stopping resistance provided by coins hooked on the edge of each hole is the same,
The braking resistance acting on the motor is determined by the distance between the center of the disk and the position of each hole and the number of holes. For example,
The restraining resistance acting on the holes themselves is fconst., And the distance between the center of the disk whose diameter is increased to form a counterbore similar to that of this embodiment for each hole and the drilling position of each hole is R. For example, the braking resistance acting on the motor is 4R.fconst. If the distance between the centers of the discs 5 and 6 and the positions where the holes are formed in this embodiment is r, the braking resistance acting on the motor is obtained. The resistance is 4 · r · fconst. 4 <r> fcons by r <R
It is self-evident that t. <4 · R · fconst.
It is apparent that the load acting on the motor is smaller when the disks having the same diameter are provided side by side and half of the required amount of holes is provided in each disk.

When the discs 5 and 6 rotate while the coins stored in the lower layer of the hopper 2 are in sliding contact with the first disc 5 or the second disc 6, the coins protrude from the first disc 5. The stirring projections 12a and 12b and the stirring projection 15 projecting from the second disk 6 are provided.
a, 15b agitate these coins to change their posture and position in various ways. Then, eventually, the coin located in the lower layer portion and the through hole 10 in the first disk 5
a, 10b or the rotation position of the through holes 13a, 13b in the second disk 6, and coins pass through these through holes 10a, 10b or 13a, 13b on the cavity area 18 or the cavity area 19.
It will fall up.

Thus, the coin A dropped on the cavity area 18 through the through hole 10a in the first disk 5 and the coin B dropped on the cavity area 18 through the through hole 10b are shown in FIG. As a result, the ridges 23a and 23b provided on the back surface of the first disk 5 corresponding to these through holes 10a and 10b press and transport the cavity region 18 in the clockwise direction.
When the end of the coin A pressed and conveyed by the ridge 23a comes into contact with the side surface of the guide piece 27 as shown in FIG. 5, the coin A whose end is held by the guide piece 27 is By the pressing force, it is gradually sent out toward the cavity area 19 of the second disk 6 along the side surface of the guide piece 27. The coin chamber 26b of the second disk 6, which rotates in synchronization with the first disk 5,
It gradually rotates counterclockwise toward the joint between the cavity region 18 and the cavity region 19.

At the stage when about 1/2 of the coin A conveyed along the side surface of the guide piece 27 by the pressing of the ridge 23a is sent out to the cavity area 19, as shown in FIG. The coin chamber 26b of the second disk 6 rotating in the direction rotates to the associated portion of the cavity area 18 and the cavity area 19, and the through hole 10a of the disk 5 exceeds the position where the guide piece 27 is provided, and is renewed. It is in a state where it is possible to accept a new coin A '.

The disks 5, 6 are further rotated, and the ridges 23a
A pressed and conveyed along the side surface of the guide piece 27 by the
Is sent out to the cavity area 19, as shown in FIG. 7, the protruding piece 25b of the coin chamber 26b of the second disk 6 approaches the outer periphery of the coin A that has entered the cavity area 19, as shown in FIG. Finally, the coin A, which has come into contact with this and most of which has entered the cavity area 19, is accommodated in the coin chamber 26 b, and the coin A accommodated and isolated in the coin chamber 26 b is placed in the cavity area 1.
The sheet is pressed and conveyed in the counterclockwise direction in FIG.

The cavity region 18 passes through the through hole 10b.
The coin B that has fallen upward is conveyed in a clockwise direction over the cavity area 18 by the ridges 23b provided on the back surface of the first disk 5 corresponding to the through holes 10b. It is housed and isolated. FIG.
In the state shown in FIG. 4 and the state shown in FIG. 4, the phases of the disks 5 and 6 are both shifted by 180 degrees. Is replaced with the subscript a, the coin A
Is exactly the same as that of coin B.
The coin A that has fallen on the cavity area 18 through the through-hole 10a is always contained and isolated in the coin chamber 26b, and the coin B that has fallen on the cavity area 18 through the through-hole 10b is always in the coin chamber 26a. Contained and isolated. Since the rotation ratio of the disks 5 and 6 is 1 to 1, this correspondence is unchanged.

The second disk 6 has through holes 13a, 13a equivalent to the through holes 10a, 10b in the first disk 5.
b, and the coin sliding on the disc 6
As in the case of the disk 5 of FIG. That is, the through holes 13a in the second disk 6
As shown in FIG. 9, the coin C dropped on the cavity area 19 through the through hole 13b and the coin D dropped on the cavity area 19 through the through hole 13b correspond to these through holes 13a and 13b, respectively. Then, the projecting piece 24a and the projecting piece 24b provided on the back surface of the second disk 6 press and convey the cavity region 19 counterclockwise.

The coin chamber 26b is caught by the through hole 10a of the first disk 5 and is projected by the ridge 23a.
Each of the coin A housed and isolated in the inside and the coin B captured by the through-hole 10b and housed and isolated in the coin chamber 26a by the ridge 23b corresponds to the projecting piece 24a and the projecting piece 24b. As described above, the projecting piece 25a and the projecting piece 25b provided on the back surface of the are pressed and conveyed over the cavity area 19 in the counterclockwise direction. That is, the protruding pieces 25a and 25b are protruding pieces for pressing and conveying the coin conveyed by the first disk 5.

In the example shown in FIG. 9, the coin chamber 26a
The end of the coin B, which is housed and isolated in the cavity area and pressed and conveyed over the cavity area 19 in the counterclockwise direction, is held by the guide piece 28, and most of the coin B is pushed from the cavity area 19 by the pressing of the protruding piece 25 a. The state where the sheet is sent to the area of the discharge port 29 is shown. As already explained,
In this state, the inner concave portion of the tip bent portion 34a of the payout detector 8 is fitted with the outer periphery of the coin B as shown in FIG.
9 and is discharged to the outside through the slope 32 of the casing 7. As shown in FIG. 3B, the payout detection timing by the payout detector 8 is as shown in FIG.
And before the state of FIG.

When the second disk 6 further rotates counterclockwise, the coin chamber 2 from which the coin B has been discharged is
The coin chamber 26a is completely isolated from the lower layer coin that slides on the surface of the second disk 6, but a new coin directly enters the coin chamber 26a. Without rotating, the coin is rotated toward the joint between the cavity region 18 and the cavity region 19 while maintaining the empty state, and as shown in FIG. It will wait for containment. The projecting piece 2 of the disk 6
The coin D pressed and conveyed at 4b is paid out from the coin outlet 29 in the same manner as described above. In the state shown in FIG. 10, the suffix a of each code is replaced by the suffix b,
Is replaced with the suffix a, so that the state is the same as that in FIG.

When the through hole 13b of the second disk 6 which rotates in the counterclockwise direction exceeds the position where the id piece 28 is disposed, as shown in FIG. 11, a new coin D 'is inserted into the through hole 13b. Will be ready to accept. If the suffix a of each code is replaced with the suffix b and the suffix b is replaced with the suffix a, the state of FIG. 11 is the same as the state of FIG.

When the disk 6 is further rotated, as shown in FIG. 12, the coin A housed and isolated in the coin chamber 26b is discharged from the coin discharge port 29 by the projecting piece 25b, and the empty coin chamber 26b is removed. It rotates toward the joint between the cavity area 18 and the cavity area 19, and waits for accommodation of coins pressed and conveyed by the ridges 23a on the disk 5. If the subscript a of each code is replaced with the subscript b and the subscript b is replaced with the subscript a,
The state in FIG. 12 is similar to the state in FIG.

Thereafter, the coin payout apparatus 1 repeatedly executes the same payout cycle as described above, and removes the coin that has dropped onto the cavity area 19 through the through holes 13a and 13b of the second disk 6 by using the protruding pieces 24a and the protruding pieces. While coins are directly paid out of the cavity area 19 to the coin outlet 29 by 24b, the coins dropped onto the cavity area 18 through the through holes 10a and 10b of the first disc 5
a, 23b, the material is sent from the cavity area 18 to the cavity area 19, and the coin chamber 2 of the second disk 6 is
Payout is made to the coin outlet 29 through 6b and 26a.

During this time, the coins located in the lower layer of the hopper 2 are separated from each other by the protrusions 1 provided on the respective disks 5 and 6.
2a, 12b and 15a, 15b are agitated as a whole, and the through holes 10a, 10b and 13a, 13b provided in the two disks 5, 6 are rotated around the different positions. The coins are evenly captured from various positions on the bottom surface, and since the hopper 2 itself is not provided with an inadvertent inclination or a reduced diameter portion, the coin storage state is not easily biased, and the occurrence of bridges is prevented. As a result, erroneous determination of the stored amount by the empty sensor is also prevented.

Further, since the bottom of the hopper 2 is formed in a substantially planar shape, when the occupied space of the hopper is the same, the storage amount of coins is substantially increased as compared with a conventional product having a slope at the bottom. If the coin storage amount is the same as that of the conventional hopper, the entire apparatus can be downsized. The means for rotating the disks 5 and 6 synchronously is formed in the same plane as the disks 5 and 6 by the teeth 16 and 17 provided on the outer periphery of the disks 5 and 6 themselves. , 6 are driven by separate drive systems to synchronize the rotation, so that the entire apparatus is downsized.

As described above, by providing the disks 5 and 6 together, the diameter of the disk is reduced, and the load of the coin acting on the disk and the load on the motor caused by the catch of the coin are reduced as described above. Further, as described above, the number of holes to be bored per disk is reduced, so that a counterbore for reducing braking resistance can be sufficiently formed.

[0049]

According to the coin payout apparatus of the present invention, coins to be paid out are captured on the entire bottom surface of the hopper by disposing and disposing through holes for capturing coins on a plurality of disks. This eliminates the need to guide the coin by narrowing the diameter of the hopper or tilting the bottom of the hopper toward the position where the disc is to be placed.In addition, the coins are evenly taken out while stirring each part of the hopper bottom with the projections. In addition, the coins are less likely to be deviated in the stored state, and the occurrence of a bridge is prevented.

Further, since the number of through holes provided per disk is reduced, a sufficient counterbore can be formed for each through hole, and the diameter of each disk is reduced, thereby reducing the stopping resistance. Since the length of the arm involved in the moment is reduced, the substantial stopping resistance applied to the disc by the contact of the coin in the hopper and the catch of the coin in each through hole is reduced, and the load on the motor is reduced.

Further, since each disk is rotated synchronously by the motor for rotating any one disk and the teeth formed on the outer periphery of each disk, a special interlock for synchronously rotating each disk is provided. No mechanism is required, and an increase in the size of the apparatus and an increase in manufacturing costs caused by the simultaneous installation of disks are suppressed.
