DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for lifting coins used in play equipment such as a slot machine.

[0002]

2. Description of the Related Art Coins used in slot machines installed in pachinko parlors and the like are collected inside so-called islands, distributed and transported therein, and then supplied again to each slot machine and coin lending machine. Have been.

In the process of transporting coins inside the island, there are a portion for horizontally moving the coin and a portion for vertically rising the coin. A transport conveyor or the like is used in a portion for moving coins horizontally, and a bucket elevator or the like is used in a portion for vertically moving coins. A transport device combining these components is also often used.

As a conventional coin (medal) transport device,
For example, JP-A-3-202092 and JP-A-4-3.
There is one disclosed in, for example, Japanese Patent No. 16189.

[0005]

In a coin (medal) transporting device which has been used conventionally, a so-called lifting device used in a step of transporting coins upwards, uses a bucket elevator. The bucket elevator accommodates coins in a bucket mounted on a belt body and lifts the coins by rotating the belt body.

On the other hand, a lifting device employed in a coin (medal) transfer device disclosed in JP-A-3-202092 and JP-A-4-316189 has a large number of support plates in a casing. This is a structure in which belts arranged in a line are arranged, and coins are placed on a support plate that rises by rotation of the belts and are lifted.

[0007] In these lifting devices, the speed at which coins are lifted is slow, and coins during lifting are likely to fall from buckets and support plates. The dropped coins accumulate in the bottom of the casing and must be taken out periodically, which is troublesome. Further, since a bucket, a support plate, and the like protrude from the belt body, a wide space is necessary for a passage path of the belt body.
For this reason, the casing of the lifting device becomes large and cannot be installed without a large space.

Further, there is a limit to increasing the running speed of the belt body to increase the transport speed of the conventional coin lifting device, and therefore, the coin lifting speed is often increased by increasing the size of the device. For this reason, pachinko parlors, where the inside of the island is narrow and a wide installation space cannot be secured, cannot be easily installed.

Further, when a flat belt is used in a conventional coin lifting apparatus, coins are usually conveyed on the tight side of the belt due to belt design. At this time, a top (head) pulley is driven. It is necessary to install an electric motor (motor) on the upper part. However,
The lower part of the island end to be installed is connected to the space under the game table and there is some space, but the upper part is narrow, so it is not possible to secure the installation place with a conventional coin lifting device with a motor etc. mounted above. Many.

It is an object of the present invention to provide a coin lifting device having a simple structure and a compact size, which has a high lifting speed.

[0011]

In order to solve the above-mentioned problems, a coin lifting device according to the present invention comprises a plurality of belt members arranged and arranged in parallel running sections in which the belt members contact each other and run. The stored coins are stored between belt bodies in a parallel running section and are transported.

[0012] In the parallel running section in which the belt members are in contact with each other and run, coins are accommodated between the belt members and lifted, so that coins can be continuously lifted and the lifting speed is greatly increased. Also, there is no coin drop during the unloading process. Further, since a bucket or the like is not required, the structure is simple, and the size can be reduced. Furthermore, since the coins are accommodated between the belts and fed up, there is no need to convey the coins on the tight side of the belts, so that there is no need to mount a motor for driving the belts above the apparatus. That is, since a motor for driving the belt body and the like can be attached below the apparatus, it is easy to secure an installation space on the island of the pachinko parlor.

Further, the coin lifting device of the present invention is characterized in that the belt body is provided with a protrusion for holding a coin. By providing a protrusion for holding coins on the belt body, a large number of coins can be stored, so that the lifting speed can be increased and coins can be prevented from falling.

The coin lifting device of the present invention is characterized in that an auxiliary member for maintaining a contact state is provided in a parallel running section of the belt body. When coins are stored between the belt bodies,
Since the distance between the belt members is increased due to the thickness of the coin, and the coin may fall, an auxiliary member is provided in the parallel running section to maintain the contact state between the belt members.

Here, the coin lifting device of the present invention is characterized in that the auxiliary member is an auxiliary plate or an auxiliary roller which is in contact with the belt body. By providing an auxiliary plate or an auxiliary roller in contact with the belt body in the parallel running section of the belt body, the distance between the belt bodies is prevented from being increased, and the contact state is maintained.

Further, the coin lifting device of the present invention is characterized in that a tiltable swing pulley for urging the belt in the contact direction is provided at the start end of the parallel running section of the belt. When accommodating coins inserted at the start end of the parallel running section of the belt body, the distance between the belt bodies needs to be increased by the thickness of the coin. Therefore, a swing pulley is provided at the start end. When a coin is inserted, the swing pulley tilts and the distance between the belt members increases by the thickness thereof. After the coin passes, the swing pulley returns to its original position, so that the belt members also return to a contact state.

Further, in the coin lifting device of the present invention, a coin insertion hopper is provided at a start end of the parallel running section of the belt body,
A coin discharging chute is provided at the end of the parallel running section. The inserted coin is accommodated between the belt bodies at the start end of the parallel running section, is discharged as the belt body runs, and is discharged from the end end of the parallel running section. By providing a coin insertion hopper at the start end, coin insertion operation is facilitated. Further, by providing a coin discharging chute at the end end, coins can be discharged in a certain direction.

Here, a gate brush for adjusting the amount of discharged coins is provided at a coin discharge opening of the coin insertion hopper. The coins inserted into the coin insertion hopper are ejected from the coin ejection slot.However, by providing a gate brush, the amount of coin ejection is kept constant, so that the coins can be stored and lifted smoothly between the belt bodies. The efficiency of lifting work is improved.

[0019]

Embodiments of the present invention will be described below with reference to the drawings. 1 is a vertical sectional view of a coin lifting device according to an embodiment, FIG. 2 is a front view of a coin insertion hopper, FIG. 3 is a plan view of the same, FIG. 5 is a front view of the main lift belt, and FIG. 6 is a sectional view taken along line AA of FIG.

As shown in FIG. 1, in the coin lifting device 10, the main belt 11 is wound around a driving pulley 13, a main belt tension pulley 16, a swing pulley 14, a main belt head pulley 15, and a snap pulley 17. I have. The swing pulley 14 and the main belt head pulley 15 are made of soft rubber.

The holding belt 12 includes a swing pulley 14, a holding belt snap pulley 20, a holding belt tension pulley 19, and a holding belt head pulley 1.
It is wrapped around 8. The holding belt 12 has elasticity in the surface direction.

The main belt 11 is located between the swing pulley 14 and the main belt head pulley 15.
A parallel running section 31 is provided in which the and the pressing belt 12 travel with their surfaces in contact with each other. In addition, parallel running section 3
In order to increase the contact pressure, a pinch roller 21 pressed by a spring 22
And a main belt back plate 25 is provided on the back side of the main belt 11.

When the drive pulley 13 is rotated by the motor 30, the main belt 11 travels. However, since the holding belt 12 having no drive system is also in contact with the main belt 11 in the parallel running section 31, the main belt 11 is generated at the contact portion. It travels with the main belt 11 due to frictional force.

As described above, the coin lifting device 10 arranges the main belt 11 and the holding belt 12 in the parallel running section 31 in which the belts run in contact with each other, and runs the inserted coin C in parallel. It is housed between the two belts in the section 31 and lifted.

In the parallel running section 31, the coins C are accommodated between the belt bodies and lifted, so that the coins can be continuously lifted and the lifting speed is greatly increased. Since the coins are stored and lifted between the two belts, the coins do not fall during the lifting process, and a bucket or the like is not required, so that the structure is simple and the size can be reduced.

In addition, since the coin C is stored between the belts and transported, it is not necessary to transport the coin C on the tight side of the belt as in the conventional coin transporting device. Motor 30 can be mounted below. Therefore, it is easy to secure an installation space even on an island where there is no room in the upper space.

As shown in FIGS. 5 and 6, the coin lifting device 10 has protrusions 34 and 35 for holding coins on the surface of the main belt 11. By providing the protrusions 34 and 35 for holding coins on the surface of the main belt 11, a space is created between the belts when they come into contact with the pressing belt 12 in the parallel running section 31, so that many coins C are stored in this space. it can. Therefore, a large amount of coins C
Can be transported, increasing the transport speed,
Since the coin C being unwound is surrounded by the projections 34 and 35, the coin C can be prevented from falling.

On the other hand, in the coin lifting device 10, if the coins C are accommodated between the two belts, the distance between the belts increases due to the thickness of the coins C, and the coins C may fall. In order to increase the pressure, a pinch roller 21 pressed by a spring 22 is provided on the back side of the holding belt 12, and a main belt back plate 25 is provided on the back side of the main belt 11. As a result, the two belts are in strong contact in the parallel running section 31, so that coins do not drop during lifting.

As shown in FIG. 4, when the coin C inserted at the start end 36 of the parallel running section 31 is accommodated, the distance between both belts needs to be increased by the thickness of the coin C. In the lifting device 10, the swing pulley 14 is provided at the start end 36 of the parallel running section 31. Since the swing pulley 14 is pivotally supported by the swing arm 27 and the swing arm 27 is pivotally supported by the fixed shaft 32, the swing pulley 14 can be tilted about the fixed shaft 32. The tip of the swing arm 27 is connected to the main body casing 33 via a spring 26 and urges the swing pulley 14 toward the main belt 11.

Therefore, when the coin C is inserted between the two belts at the start end 36, the swing pulley 14 tilts and the distance between the two belts increases by the thickness thereof. Since the swing pulley 14 returns to its original state, both belts return to a contact state. Further, since the swing pulley 14 is made of soft rubber, the surface of the swing pulley 14 is depressed when a coin C or the like passes. In addition, since the holding belt 12 has elasticity in the surface direction, it can appropriately cope with the tilting of the swing pulley 14.

Further, the coin lifting device 10 is provided with a hopper 28 for inserting coins at the start end 36 of the parallel running section 31.
Shoot 2 for coin release at the end 37 of the parallel running section 31
4 are provided. The provision of the hopper 28 facilitates coin insertion, and the provision of the chute 24 allows the coin C to be discharged in a certain direction. Further, since the guide plate 23 is provided inside the chute 24, the coins C discharged from the end 37 of the parallel running section 31 are evenly dispersed by the guide plate 23 and fall.

Here, a gate brush 2 for adjusting the amount of discharged coins is provided in the coin discharge opening 38 of the hopper 28 for inserting coins.
9 are provided. The coin C inserted into the hopper 28 is discharged from the coin discharge port 38. However, since the coin discharge amount is kept constant by providing the gate brush 29, the coin C can be stored between the two belts at the start end 36 and Unloading is performed smoothly and the efficiency of unloading work is improved.

The gate brush 29 has the function of suppressing unnecessary movement caused when the coin C is transferred onto the main belt 11 and passing an appropriate amount thereof. Since the belt can be run at a higher speed, the amount of pumping per unit time can be greatly increased.

As described above, in the coin lifting device 10,
The coin C inserted from the hopper 28 is the main belt 11
Although the amount of coins passing therethrough is limited due to the resistance of the gate brush 29, the amount of coins passing according to the lifting capacity of the apparatus has passed, and the main belt 11 and the holding belt 12 contacted by the swing pulley 14 Is housed between.

At this time, if the resistance is generated due to the amount of the coin C passing through the outer peripheral portion of the swing pulley 14, the swing pulley 14 is fixed against the force of the spring 26 at the tip of the swing arm 27 as described above. Axis 3
The coin C is passed by tilting around the center 2. Further, since the swing pulley 14 is made of soft rubber, a smooth passing state can be obtained because the surface is depressed when the coin C or the like passes.

Thereafter, the two belts rise while contacting each other. When the two belts reach the end 37 of the outer peripheral portion of the main belt head pulley 15 after passing through the parallel running section 31, the main belt 11 and the holding belt are pressed. Since the traveling direction is separated from the belt 12 and the contact is released, the coin C is discharged into the space by inertia and falls from the exit of the chute 24. The main belt head pulley 15 is made of soft rubber, and has a function of being depressed when the two belts containing the coins C pass, so that they can pass smoothly.

By using the coin lifting device 10, coins can be efficiently transported at a high speed. However, the coin lifting device of the present invention is not limited to this use, and therefore, the coin lifting device 10 is not limited to this application. It can be widely used in the field of transporting other similar articles.
