Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coin or medal supply device, and more particularly, it can easily eject coins and the like by rotating a screw and has a coin ejector on a coin conveying path useful for amusement facilities. The present invention relates to a coin or medal supply device.

[0002]

2. Description of the Related Art Conventionally, in amusement facilities such as pachinko machines and slot machines, coins or medals (collectively referred to as coins, etc.) are collected from each of the consecutively connected game machines, and coins are distributed to each game machine. A belt conveyor system is generally used as a supply device. For example, in the case of a pachinko amusement park, a common belt conveyor is installed on the back side of the pachinko machine (hereinafter called “sima”) that is continuously installed, and coins etc. thrown into the ball rental machine attached to the pachinko machine are placed on this conveyor And is collected at one location either directly or through several stages of conveyor transfers. Therefore, the belt conveyor mechanism, a guide for guiding coins, etc. are arranged in a limited space on the back side of the stripe so as not to interfere with the mechanism of the game machine.

[0003]

However, it is unavoidable that a gap is formed on both sides in the width direction of the belt conveyor, and a coin or the like fits into the gap, resulting in defective operation. However, there is a problem that the loop joint portion of the belt is broken in 1 to 2 years due to deterioration over time. When such a problem occurs, the operator is forced to work in a narrow space, disassembling and repairing the device.
A great deal of labor and time are required for re-adjustment of the assembly.

Further, since the pachinko amusement park has a different scale and an existing belt conveyor cannot be used as it is, it is necessary to manufacture a belt conveyor according to the length of the strip each time, and in construction and assembly, It requires high accuracy such as belt meandering prevention and tension adjustment, resulting in high construction cost. Further, the belt conveyor has a complicated structure, and thus the device cost is high. Therefore, the equipment cost is high.

Further, in the belt conveyor, it is difficult to form a coin transfer path having a curved portion and to supply coins or the like to a desired place during coin transfer. As described above, the conventional belt conveyor type coin transfer device is not only expensive to install, but also has a complicated structure, which makes it difficult to install and disassemble the device. When it occurs, there is a problem that it cannot be easily restored to the original.

In particular, in the above belt conveyor system, when a coin or the like is to be lifted up to a place having a height difference, the belt conveyor must be provided with an inclination, and when the inclination angle becomes tight, the coin or the like is caused by its own weight. Has the problem that it cannot slide down the slope and be pumped. Therefore, especially when a limited space on the backside of a strip is effectively used like a pachinko amusement park to collect coins and supply coins etc. to each game machine after washing, especially coins etc. to the game machine. It is indispensable to provide a coin hoisting unit in the coin transporting path when supplying coins, and in the current market, there is an eager desire to develop a device that can easily hoist coins and the like.

The object of the present invention is to solve the above problems, to install and disassemble with a simple structure, to suppress the occurrence of mechanical troubles, and to reliably pump coins or the like to a place having a height difference. It is to provide a coin or medal supply device that can be used. It is another object of the present invention to provide a coin or medal supply device that can form a coin or the like with a curved path and a coin or a medal can be supplied to a predetermined place.

[0008]

As a result of repeated studies to solve the above problems, the present inventors have used a screw having a coil shape, hold a coin or the like on the screw on a carrying base, and rotate the screw. By doing so, they have found that coins and the like can be easily conveyed in the axial direction of the screw. Furthermore, they have found that coins and the like can be lifted to a place having a height difference by using the above-mentioned screw, thus completing the present invention.

That is, in the coin or medal supply device of the present invention, the axially extending screw for moving the coin or medal in the standing state and the screw rotatably attached to move the coin or medal in the standing state. And a guide rail for holding the coin or the medal in a standing state, which is disposed at a position facing the conveyor base with the screw sandwiched therebetween, and the coin or the medal moves in the axial direction of the screw by the rotation of the screw. A coin or medal supply device configured as described above, in which a hoisting unit is provided in the coin or medal transport path, and a lid is attached to at least the top of the guide rail of the hoisting unit. , Preferably the screw is a flexible screw in which a cord is spirally provided on a flexible rod. In addition, the transfer base and the guide rails are housed in an integrated housing, and a discharging portion for discharging coins or medals is formed in the conveying path along which coins or medals move. It has been done.

[0010]

According to the above construction, by rotating the screw, coins and the like supported by the guide rail on the conveying base in a standing state and held in the pitch width of the screw are extruded in the axial direction of the screw. The coins can be moved, and can be easily lifted even if the lift portion is formed on the coin transport path. Further, since the lid is provided on the top of the guide rail to close the outer side, even if the above-mentioned lifting unit is a path for vertically lifting coins, for example, the coins fall off from the guide rails outward. Is prevented. Further, the coin or medal supply device is composed of a screw, a conveyance base and a guide rail, and has a simple structure,
Installation and disassembly of the device become easy, and structural troubles can be suppressed. In addition, since the coin can be conveyed and lifted in the axial direction of the screw while preferably being rotated while standing, the abrasion of the conveying base can be reduced.
Also, by using a flexible screw as the screw, it becomes possible to easily lay it not only on a straight line but also on a supply path for a coin or the like having a curved portion, and this supply path for the coin or the like lifts the coin or the like to a place having a height difference. Even with the coin hoisting unit for sending, it is possible to smoothly hoist coins and the like. Further, when the screw is housed in the housing in which the carrying base and the guide rail are integrated, coins and the like are carried in the housing, and the coin and the like are prevented from falling out. At the same time, noise during transportation of coins and the like can be significantly suppressed. Further, when the coin discharge portion is formed in the transfer path of coins or the like, it becomes possible not only during the transfer but also for supplying the coins being lifted to a desired place.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A detailed description will be given below of the embodiments of the present invention with reference to the drawings. FIG. 1 is a schematic view showing the basic structure of a coin or the like supply device of the present invention. In the sectional view of FIG. 1A, S is a coin or medal supply device,
A screw 1 for moving a coin or a medal C (hereinafter referred to as a coin C) in a standing state, and a carrying base 2 to which the screw is attached and the coin C moves in a standing state.
And a guide rail 3 for holding the coin C in a standing state by being provided at a position facing the conveying base 2 with the screw 1 interposed therebetween. Guide rail 3 above
The outer side can be closed by providing the lid 5 on the top of the. Further, the screw 1 is
As shown in the partially cut-away top view of FIG. 1B, the pitch width P
The coin C has a diameter D and extends in the axial direction, and the coin C is held in a standing state by the guide rail 3 within the pitch width P of the screw 1.

In the present invention, the pitch width P of the screw 1 is determined by the coin transport speed, the size of coins, the number of coins to be transported, the rotation speed of the screw, etc.
In order to convey coins or the like which are usually used in amusement machines, it is appropriate that the pitch width is not more than twice the diameter of the coins or the like, preferably about the same distance as the diameter of the coins or the like. Further, the diameter D of the screw is determined by the size of the coin or the like to be conveyed, but it is preferable to have at least ½ of the diameter of the coin.

Any screw may be used as long as it has a coil shape. For example, a coiled body such as a coiled wire alone or a screw in which a cord is spirally provided on a rod or a spiral continuous groove is formed on the rod. A screw etc. can be used.

The transfer base 2 is one on which the coin C moves, and preferably the coin C moves while rotating in a standing state. Further, the guide rail 3 has a passage 4 through which the coin C is inserted in a standing manner, guides the coin C within the pitch width P of the screw 1, and moves the upper part of the coin C in the width direction of the transport base 2. This prevents the coin C from standing and keeps the coin C in a standing state. In the present invention, in order to securely hold the coin C in the standing state, the width of the guide rail 3 is 3 times or less, preferably 2 times or less, and particularly preferably 1.1 to 1. It is suitable to make it about 5 times.

In the coin supply device of the present invention, a transfer path for coins and the like including the lifting portion is formed by the transfer base, and a screw corresponding to the shape of this path is rotatably attached to the transfer base. At least one end thereof is connected to a drive source such as a motor. Next, a coin or the like is guided to the screw, and a guide rail is provided at a position where it can be held in a standing state. It is also possible to insert a screw so as to be rotatably attached to the transport base after forming a transport path for a coin or the like with the transport base and the guide rail.

In the present invention, as shown in FIG. 1 (a), at least the guide rail 3 of the lifting section in the transfer path for the coins and the like is provided with a lid 5 at the top to close the passage 4. It is characterized by This lid 5
Are formed by fitting or joining to the top of the guide rail 3 or integrally with the guide rail. However, it is preferable that the guide rail of the lifting section has a gap between the lid 5 and the transport base 2 that is slightly larger than the diameter of the coin C.

According to the above construction, when the screw 1 is rotated, the coin C held in the standing state is pushed out by the screw 1 and moves axially upward in the lifting portion. Since the lid 5 is provided on the guide rail of the section, the lifting section is steeply inclined, for example, when the coin C is almost vertical.
Even in the coin lifting path for lifting the coins and the like, it becomes possible to prevent the coin C from falling out of the passage 4 of the guide rail.

As described above, since the coin C is easily lifted in the standing state, the frictional resistance when the coin is moved becomes small, and the coin C can be lifted with a small rotating torque, and the conveying base and the screw are worn and damaged. Can be suppressed. Further, the coin or medal supply device of the present invention,
As described above, since the number of components is small and the structure is simple, the device can be easily assembled and disassembled, and the entire device can be made compact.

In the present invention, the number of revolutions of the screw may be set according to the amount of coins to be carried, but is usually 50 to 1000 revolutions / minute, preferably 100 to 500.
Rotation / minute is appropriate.

In the present invention, as the screw, the flexible screw (PC
The use of T application publication WO 91/06493) is preferable because it can be easily laid on a lifting portion such as a coin having a curved portion.

The screw rod used in the present invention may be any rod as long as it does not bend due to the rotation of the screw and has sufficient rigidity to transmit the rotational torque applied from one end of the screw to the other end. A rod having both flexibility and flexibility can be preferably used. For example, the rod may be entirely made of resin, but in order to impart good flexibility, a metal wire is braided on the surface of the resin layer, or a resin layer is used. A metal wire may be stretched inside or a core material of the metal wire may be provided in the resin layer. However, in order to provide further flexibility and rigidity, it is preferable to use a metal rope having a known structure.

Examples of the metal rope include steel, nickel, cobalt and alloys thereof. The structure of this metal rope itself is basically the same as that of a well-known steel rope, that is, a structure in which several (or several tens) strands are twisted together and several more strands are twisted together. Is. Preferably, it is composed of several layers of densely wound coil wire, each layer is a multiple winding of several coils at one pitch, and adjacent layers are sequentially reverse winding. Further, there is no particular limitation on the normal twist, the Lang twist, and the S twist and the Z twist, which are the twisting directions of the ropes.

When the rod is a metal rope, the cord may be directly wound around the metal rope in a spiral shape. However, since the cord may be ground by the metal rope due to repeated conveyance of coins, the cord is usually made of metal. The rope contains a lubricant for reducing the friction between the wires, and a coating layer for covering the metal rope is provided in order to prevent evaporation of the lubricant and enhance its holding effect. preferable. The larger the thickness of the coating layer is, the better the inherent flexibility of the metal rope is impaired. Therefore, it is preferable that the coating layer be as thin as possible for a rod having a predetermined diameter. For example, the diameter of the metal rope is 6.0 mm, but the thickness of the coating layer is usually 0.1 to 2.0 mm, preferably 0.2 to
It is 0.6. Further, it is desirable that the thickness of the coating layer is as uniform as possible in order to increase the concentricity of the screw. Specifically, when the thickness of the coating layer is t, [t (maximum)-
The value of t (minimum)] / t is 0.1 or less, preferably 0.0
It may be 5 or less. A screw satisfying this numerical value can rotate at a higher speed.

The coating layer may be coated by a conventional extrusion coating technique using a resin material. For example, in the case of extrusion coating, similar to the insulation coating of electric wires, while the metal rope is fed out in one direction under constant tension, the resin material is melt-extruded from the die arranged in the axial direction of the metal rope, and at the same time the metal rope is The coating is done as above.

When the coating layer is provided on the metal rope, the rotation torque is usually applied from one end of the screw to rotate the entire screw during coin transportation, so that the metal rope and the coating layer may rotate integrally due to torque transmission. is important.
To this end, it is preferable to adopt a structure in which the contact area between the metal rope and the coating layer is large and the coating layer does not slide on the metal rope. For example, an appropriate number of protrusions may be provided on the metal rope, a wire may be spirally wound around the metal rope, and a brim may be provided on the metal rope.

On the other hand, the material of the cord provided spirally on the rod may be metal or resin, but at least the surface of the cord is preferably made of resin for the following reasons. That is, in the device of the present invention, the screw is normally locked to the transport base and rotated. When the screw rotates,
The cord slides on the locking surface, causing significant contact friction,
The cord and the carrier base are worn out severely. Therefore,
In order to minimize the wear of the cord and the transportation base and reduce the maintenance cost, it is advantageous that the surface layer of the cord is made of resin rather than metal.

A more desirable cord is to have a core made of a fiber bundle. The cord with the core is
This is advantageous in that it is possible to suppress the elongation of the cord due to the temperature rise due to frictional heat or the tensile load, and as a result, it is possible to prevent the disorder of the spirally wound cord pitch. In the present invention, the buckling rate of the cord is specified as 3.0% or less. The buckling rate is 1/100 of the tensile strength of the core when the resin layer is removed from the cord in which the core is covered with resin.
The length L when tensed the core with zero force, expressed as a percentage of initial length L ₀ of the difference between the initial length L ₀ before the resin layer is removed. That is, the buckling rate ε is ε = (L−L ₀ ) / L ₀ × 10
It is obtained from the formula of 0 (%). However, if the buckling rate of the core body is greater than 3.0, the cord tends to expand when tension is applied to the core body due to the contraction of the core body, so the buckling rate is 3.0% or less, preferably Is 0.3% or less, more preferably 0.1% or less, and particularly preferably 0.05% or less, and cords having this buckling rate have practically almost no elongation. The present invention also includes the case where the buckling rate takes a negative value, that is, the case where L is smaller than L ₀ . In such a case, the core in the polymer cord exists in a state in which it is forcibly stretched beyond the proper length,
When the resin layer is removed during the measurement of the buckling rate, the resin layer is released from the forcible extension and contracts. Therefore, when the contraction length is larger than the length L when the tension is applied, as a result ( L
The −L ₀ ) value will show a negative value. If the buckling rate is excessively negative, it may lead to cutting of the core during use of the screw, but a range of more than -0.5%, particularly more than -0.1% is preferable.

The material of the fiber bundle serving as the core is not particularly limited as long as it acts as a tension member of the cord. Examples of the fiber bundle include natural fibers [(cotton, flax, hemp, coconut fibers, and other plant fibers), (wool,
Animal fiber such as silk), semi-synthetic fiber (eg acetate), synthetic fiber (eg polyamide fiber (eg 6-
Nylon etc.), polyester fiber (eg Kevlar,
Tetron etc.), polyacrylonitrile fiber (eg acrylic fiber, modacrylic fiber etc.), polyvinyl alcohol fiber, polyvinyl chloride fiber, polyvinylidene chloride fiber, polyolefin fiber (eg polyethylene, polypropylene etc.), polyurethane fiber, inorganic (For example, glass fiber, graphite fiber, boron fiber, various metal fibers, etc.) and the like. Among them, Kevlar is suitable in terms of high strength, fatigue resistance, heat resistance, low creep property, and the like. The core body is usually prepared by twisting a large number of fibers, and the thickness of the fiber bundle depends on the material of the core body and the outer diameter of the cord, but is 1000 to 15000 denier, preferably 1500 to 9000 denier. The number of twisted fibers in the fiber bundle is 666 to 10000, preferably 1000 to 6000.

There is no particular limitation on the organic layer or the inorganic resin constituting the whole rod or the coating layer on the metal rope and the cord. For example, as an organic or inorganic resin material,
Polyolefins and copolymers thereof (for example, polyethylene, polypropylene, ethylene / vinyl acetate copolymer (EVA), ethylene / ethyl acrylate copolymer (E
EA) and the like, and polyalkylenes thereof and copolymers thereof, and as polyethylene, particularly, ultrahigh molecular weight polyethylene (UHMWPE: usually having a molecular weight of 1,000,000 or more, preferably 16.50 million or more), low molecular weight polyethylene,
High molecular weight polyethylene and the like are exemplified], polyether (for example, polyacetal, polyphenylene ether and the like), polyamide (for example, 6-nylon, 6,6-nylon, 11-nylon and the like), fluororesin (for example,
Examples thereof include polytetrafluoroethylene (PTFE), tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer, etc.) and polyesters (eg, polyethylene terephthalate, polybutylene terephthalate, etc.).

The above ultra high molecular weight polyethylene includes
For example, JP-A-63-10647 and JP-A-63-126
The modified ultrahigh molecular weight polyethylene described in each publication of No. 06 is exemplified. Commercially available products of this modified ultra-high molecular weight polyethylene include, for example, Fuchu Mitsui Petrochemical Industry Co., Ltd.
For example, the product names Lübmer (Lübmer L5000, Lübmer L4000, Lübmer L3000) and the like are exemplified.

In the present invention, especially the surface of the cord comes into contact with the coin and slides on the carrying base, so that it is preferable to consider wear resistance. To obtain high wear resistance, the specific wear amount is 5 × 10 ⁻⁴ mm ³ / Kg · m or less, preferably 5 × 10 ⁻⁵
mm ³ / Kg · m or less. However, the specific wear amount is a surface pressure of 3
Kg / cm ² , sliding speed (peripheral speed) is 33.3 m / min, mating material is stainless steel (SUS304), and sliding test time is 168 hours. As a condition for further improving the durability of the screw, the dynamic friction coefficient of the resin used for the cord is 0.4 or less, preferably 0.2 or less. However, the dynamic friction coefficient here refers to steel with a surface roughness (Rz) of 6 μm as the counterpart material, and mainly refers to the sliding friction coefficient, the surface pressure is 7.5 Kg / cm ² , and the sliding speed is 12 m / min. It is a value under the condition of.

In the production of the screw, the cord may be spirally provided on the flexible rod by integrally forming the cord and the rod, or by separately producing the cord and the rod and winding the cord around the rod. Adhering or fusing at the time of winding or adhering or fusing after winding is enumerated. When the above cord is wound, in order to prevent pitch irregularity of the cord, when the surface layer of the rod is made of resin, it is preferable to wind while winding the cord into the resin surface layer.

Further, it is preferable to form a cord fixing spiral groove on the rod. By providing the spiral groove, the cord is wound while being fitted in the groove, so that the cord pitch is less disturbed when the screw is rotated, as compared with the case where the cord is simply wound on the rod.

Further, in order to surely prevent pitch irregularity of the cord, when at least the surface layer of the rod and the entire cord are made of resin, it is preferable to integrally form both. Alternatively, after the cord is wound around the rod, the whole may be covered with a baking layer of a coating material made of a polymer or a resin layer made of a heat shrinkable tube.

In the present invention, when a flexible screw formed by spirally forming a cord on a flexible rod is used as the screw, a curved portion can be easily formed. Therefore, the coin has a curved portion for feeding the coin to a high place. This is preferable because it can be easily installed in the feeding route. Needless to say, it is also possible to lay it on a straight line feeding path.

Examples of the material for forming the above-mentioned transfer base and guide rail are steel, aluminum, brass,
Metals such as copper, engineering plastics, general-purpose resins such as polyethylene, ABS, PVC, PP, ceramics, and wood can be used.

In the present invention, the screw is rotatably provided on the carrier base. However, when the screw is locked, the screw and the carrier base slide against each other, which causes great wear. Therefore, in the present invention, it is particularly preferable that at least the surface layer of the screw and the transport base is made of a resin having excellent wear resistance.

As the above-mentioned resin having excellent wear resistance, among the above-mentioned resins, polyethylene satisfying a specific wear amount and a dynamic friction coefficient of a specific value, particularly UHMWPE (among others, Lübmer), polyether (especially polyacetal), Polyamide (particularly 6-nylon) is applicable. Above all, Lübmer is particularly preferable in terms of sliding resistance and durability. Lyumar is an ultra-high molecular weight polyethylene that can be extruded and has self-lubricating properties (specific wear: 2 × 10 ^-5 mm ³ / Kg ・
m or less). It also has excellent chemical resistance and mechanical strength equivalent to engineering plastics (tensile strength at break: 440-530 kg / cm ² , flexural modulus: 165.
100 to 18400 Kg / cm ² ).

In order to further improve the durability of the screw, in addition to the above specific wear amount and dynamic friction coefficient, these conditions may be used in combination, but a wear resistance improver may be added to the resin material. Absent. Typical examples of such abrasion resistance improvers include carbon black (particularly ultrafine carbon black), whiskers such as polytetrafluoroethylene and potassium titanate, and brass powder. The compounding amount is usually about 5 to 30 parts by weight with respect to 100 parts by weight of the resin. The wear resistance improver is preferably fine particles.

Further, in the present invention, when the screw is rotatably supported with a gap between the screw and the conveying base, abrasion and damage of the screw and the conveying base can be reduced. It is desirable that this gap be as narrow as possible in order to make the device compact, and at most 2
mm, preferably 0.8 mm or less.

As described above, since the coin or medal supply device of the present invention has a simple structure, the structure of the entire device can be simplified and made compact. Therefore, game machines such as pachinko, pachislot, and slot machines, ticketing machines,
It is useful for collecting and supplying coins, using a limited space such as coin lockers and vending machines. Further, since the present invention forms the coin lifting section, it becomes possible to form a series of coin transport paths for collecting, washing, lifting, and supplying of coins. In particular, coins are frequently collected and supplied. It is useful for supplying coins or medals for pachislot machines and slot machines.

The coin or the like supply device of the present invention has the above basic structure, but may have the following structure.
As shown in FIG. 2A, when the side guide 22 is provided to hold the coin C between the screw 1 and the screw 1, it is possible to prevent the coin C from falling off the side of the device S. . As the side guide 22, various shapes such as a linear body, a rod-shaped body, a belt-shaped body and a wall-shaped body can be used. The side guides are located at least on the side of the center of the coin to be carried. When this side guide is a belt-shaped body or a wall-shaped body, if this width is at least 30% of the diameter of the coin, the coin is held stably and is prevented from falling out from the side of the device. It will be done and is preferable.

A preferred lateral guide is shown in FIG.
As shown in (d), there are L-shaped, U-shaped, and U-shaped cross-sectional shapes (in this case, the bottom curved portion thereof functions as the transport base) that can be integrally molded with the transport base 2. At this time, the guide rail 3 may be integrally formed. Further, as shown in FIGS. 2C to 2D, when the side guides 22a and 22b facing each other are provided, the coins C ₁ and C ₁ are respectively provided between both side portions of the screw 1 and the side guides. Hold C ₂ and be able to transfer coins in two rows.

Further, as shown in FIG. 3, if the screw 1 is housed in the housing 6 formed by integrally forming the side guides 22a and 22b and the guide rail 3 on the carrying base 2, the coin 1 will be stored. Since C moves in the housing 6, it becomes possible to more reliably prevent the coin C from falling out of the coin lifting section. In addition, noise when the coins are lifted up can be significantly suppressed.

Further, by providing a coin discharging section in the conveying path, the discharged coins can be collected or supplied to a desired place. For example, as shown in FIG. 4 (a), when a predetermined portion of the carrying base 2 is opened to provide a coin discharging portion 7, coins will drop downward when passing over the discharging portion 7. , Can be discharged to a desired place. Further, if a shutter that is released by the weight of the coin is attached to the coin discharge portion 7 of the above-mentioned transport base 2, when the coin passes over this shutter (not shown),
It will fall downward. Further, as shown in the schematic view of FIG. 4B, a solenoid 8 is operated on the basis of, for example, a coin supply signal, and a shutter 8 which can be opened and closed by the solenoid is attached to the discharge section 7. Only then can the opening be released to allow the required amount of coins to drop downwards. In addition, if a predetermined portion of the side portion of the guide rail on the coin holding side of the coin transport path is omitted to provide a coin discharge portion, coins will be discharged sideways when passing through this discharge portion. , Will be able to supply to the desired place. Also, FIG.
As shown in the partially cut-away schematic cross-sectional view of (c), if the coin ejecting portion is a single-opening door 3 and the door 3 is openable / closable based on a coin supply signal, the required amount can be increased only when necessary. The coin can be discharged sideways.

FIG. 5 is a side sectional view showing an example in which a 500-yen coin feeding device is mounted, and is the U shown in FIG. 2 (d).
The letter-shaped transport base 2 forms a 500 coin feeding path having a slope of 45 degrees with respect to the floor, and both ends thereof are fixed. As a screw, a rod with 6 mmφ metal rope coated with 0.4 mm thick resin has a buckling rate of 0.05%, 50
A Lube Marcord with a 00 denier Kevlar as a tension member is wound up at a 40 mm pitch, and a flexible screw 1 having an outer diameter of 15.5 mm is used.
This is supported on the U-shaped transfer base 2 by a bearing 11 at one end and rotatably locked. One end of the screw 1 supported by the bearing 11 has a motor M
And the screw 1 is adapted to rotate.

According to the above-mentioned 500-yen coin supply device, when the motor M is operated, the screw 1 rotatably supported by the bearing 11 rotates in the direction of the arrow,
The yen coin C is extruded in the direction of the arrow J and is fed.

FIG. 6 is a partially cutaway side sectional view showing another example in which a 500-yen coin feeding device is mounted, and is different from FIG. 5 in that it is integrated with the guide rail 3 shown in FIG. The case 6 forms a straight path for vertically pumping a 500-yen coin almost vertically, and both ends thereof are fixed. The flexible screw 1 is inserted into the casing 6, and one end is rotatably supported by the bearing 10 and the other end is rotatably supported by the bearing 11.

As described above, according to the coin supply device of the present invention, coins can be easily lifted. Therefore, it is possible to form a coin hoisting unit having a height difference in the coin transport path, and thus a coin collecting, washing, hoisting, and supply circuit can be formed. Particularly, a pachislot machine that frequently collects and supplies coins and the like. It is useful for supplying coins such as coins and slot machines.

Further, the structure of the entire apparatus can be simplified, the apparatus itself can be made compact, the number of parts can be reduced, and the facility cost can be reduced. In addition, the occurrence of structural troubles can be greatly reduced. Further, since the structure is simple and the device can be made compact, it can be easily attached and detached even in a narrow space, so that the operator can be freed from the difficult work of repairing the trouble in the narrow space.

Further, since the hoisting route having the curved portion can be formed, the device can be attached according to various carrying routes.
