DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game machine such as a pachinko machine, which has a butt insertion port formed on the upper surface of a storage table provided on the front side of the game machine. The present invention relates to an automatic butts collecting apparatus for automatically collecting butts.

[0002]

2. Description of the Related Art As an automatic collecting device for cigarette butts, an endless conveyor belt running in a certain direction is provided inside a storage table. There is a configuration that transports it to

[0003] The transport belt used in this type of automatic butts collection apparatus is required to have heat resistance in order to transport butts. In addition, it is desirable that there is little elongation or abrasion, etc., even when used for a long period of time, so that the time for replacement work and maintenance work can be reduced as much as possible. From these points, a thin metal belt made of metal such as stainless steel is considered to be suitable as the transport belt, and is actually used. Practically used ones have a thickness of about 0.1 mm and are formed to have flexibility in the thickness direction.

The metal conveyor belt is wound around a driving roller that rotates and a plurality of guide rollers that rotate freely, and is provided so that the rotation of the driving roller is transmitted by frictional force and runs in a certain direction. Can be In the internal space of the storage table, the butts transport portion of the transport belt passes through the upper side, and the return portion passes through the lower side. In the stored state, the butts conveying portion and the return portion of the conveying belt are guided and supported by the guide member from below. During operation, the butts fed from the butts inlet drop onto the butts transport portion of the transport belt, which transports the butts transport portion to the collection position and drops it into a collection container or the like.

[0005]

The transport belt is provided so that the center position in the width direction passes on the same plane. However, due to the imbalance of the transport belt itself and the mounting error of the driving roller and the guide roller, etc. In this case, the transport belt slightly shifts in the width direction. In particular, when a metal belt is used as the transport belt, the belt is wrapped around the drive roller and the guide roller only in surface contact, and thus the shift is likely to occur. This shift appears as a phenomenon in which the transport belt meanders at a portion where the rollers pass through the inside of the object table where the span of the rollers is long.

[0006] Incidentally, since the transport belt is accommodated in a limited narrow space, which is the internal space of the storage table, the widthwise end of the transport belt is close to the inner wall surface of the storage table. The storage table is composed of a plurality of members that can be divided for maintenance and inspection work and the like, and the divided portion is located at substantially the same height as the conveyor belt. For this reason, when the transport belt meanders as described above, the end of the transport belt comes into contact with the inner wall surface of the storage table, and the traveling of the transport belt becomes unstable. The transport belt may stop running due to being stuck in the gap between the divided portions. Further, if the operation is performed in such an unstable state, the transport belt and the storage table are greatly worn and damaged.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to make it possible to use a thin metal belt made of stainless steel or the like as an endless belt of a belt-type conveying means so that the belt can run stably without meandering. And

[0008]

Means for Solving the Problems In order to solve the above problems, the present invention is configured as follows. That is, the butts automatic collection device according to the present invention, the butts input port is formed on the upper surface of a hollow storage table provided on the front side of the gaming machine, the butts input from the input port, the storage table In the automatic butts collection device for transferring to a predetermined collection position by a belt-type transfer device installed in the hollow interior of the hollow end, the belt-type transfer device includes a plurality of rollers including a driving roller that is driven and rotated. , And the rotation of the drive roller is transmitted to the endless belt by a frictional force to drive the endless belt to travel in a fixed direction, and at least the drive roller of the plurality of rollers including the drive roller has a width of It is characterized in that the diameter is large at the center in the direction and gradually decreases toward the outside.

If the driving roller has the above-mentioned shape, the driving roller contacts the endless belt only at the center in the width direction,
The rotation is transmitted to the endless belt through this portion. Since the endless belt always acts to receive the rotation of the drive roller at the same position in the width direction, the relative position in the width direction between the endless belt and the drive roller is maintained constant. Also,
When the rollers other than the driving roller, particularly the driven roller, have the same shape as the driving roller, the position of the endless belt in the width direction is stabilized. For this reason, the endless belt is less likely to meander even in the portion where the span between the rollers is long inside the storage table.

A groove may be formed along the outer periphery of the central portion of the drive roller. When the groove is formed, both edges of the groove come into contact with the endless belt, and the rotation is transmitted to the endless belt through both contact portions. Therefore, more stable meandering adjustment can be performed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view schematically showing the entire configuration of the automatic butts collecting apparatus. A game machine (pachinko machine) is not shown in the figure for easy understanding of the configuration. The storage table 2 of the automatic butts collection device 1
It is provided in front of a stand (so-called island) for installing a plurality of side-by-side pachinko machines (not shown), on which a case for accommodating pachinko balls and belongings of a player can be placed. I have. On the upper surface of the storage table 2, butts inlets 3 are formed at predetermined intervals corresponding to the respective pachinko machines, and a dome-shaped ashtray 4 is provided so as to cover the butts inlet 3.

As shown in FIG. 2, the storage table 2 has a transport space 5 for accommodating a belt-type transport means for transporting the butts introduced from the butts input port 3, and a basket in the ashtray 4. And a duct section 6 for discharging smoke of cigarettes. In the transport space 5, a belt guide plate 7 for guiding and supporting a transport belt 27 described later is provided in a horizontal posture.

The storage table 2 comprises a duct member 6 alone and a first component member 2A mainly constituting a top plate and a rear plate, and a second component member 2 mainly constituting a bottom plate and a front plate.
B and a metal fitting 2C having an L-shaped cross section. In the combined state, the first component 2
A engages with a groove 8 formed in the lower inner surface of the lower part A of the second component 2B, and engages with the front end of the top plate of the first component 2A. Is in contact with the upper end of the front plate. Then, the folded part 10 of the stopper 2C
Is engaged with the groove 11 formed on the outer surface of the lower end of the rear plate of the first component 2A, and the folded portion 12 of the stopper 2C is engaged with the groove 13 formed at the front end of the top plate of the first component 2A. By engaging, the first component 2A and the second component 2B are held in a combined state.

The belt guide plate 7 has a rear end formed with a groove 1 formed on the inner surface of the duct partition wall of the first component 2A.
4 and the front end is placed on a step 15 formed on the inner surface of the front plate of the second component 2B, and is supported horizontally.

The upper surface of the belt guide plate 7 and the second component 2
On the upper surface of the bottom plate of B, a plurality of rows of projections 18,..., 19,... Which are guide members for guiding and supporting the conveyor belt 27 from below are formed. Thus, the transport belt 2
Even if a liquid such as a beverage enters the transport space 5 from the butts inlet 3 by guiding and supporting the liquid 7, the liquid accumulates at the bottom of the belt guide plate 7 and the bottom of the bottom plate of the second component 2 </ b> B. Since it does not adhere to the transport belt 27, the travel of the transport belt 27 is not impaired.

When the first component 2A and the second component 2B are separated by removing the stopper 2C, the internal belt guide plate 7 and the transport belt 27 can be attached and removed (see FIG. 3).

The belt-type conveying means includes a driving roller 21 mechanically connected to an output shaft of a driving motor 20, and a plurality of guide rollers 22, 23, 2 rotatably supported.
An endless transport belt 27 is wound around the transport belts 4 and 25, and the transport belt 27 is driven to run by the power of the motor 20. As the transport belt, a metal belt made of a thin stainless steel or the like as described in the “prior art” is used. In the transport space 5 of the storage table 2, the butts transport portion 27 A of the transport belt is guided and supported by the convex portions 18,.
7B is a projection 1 formed on the bottom plate of the second component 2B.
Guided and supported at 9, ... Since the side pulled by the drive roller 21 is the butt transfer section 27A, the butt transfer section 27A runs smoothly, and the butt transfer is reliably performed.

Driving roller 21 and guide roller 2
As shown in FIG. 4, 2, 23, 24, and 25 have a beer barrel shape in which the diameter at the center in the width direction is large and the diameter gradually decreases toward the outside. For example, when the width H is about 100 mm, the diameter D1 at the center is 40 m.
m, the diameter D2 of the end is preferably about 37 mm. When the drive roller has this shape, the drive roller 2
Numeral 1 contacts the conveyor belt 27 at the center in the width direction, and transmits rotation to the conveyor belt 27 through the portion. The transport belt 27 is most stable when the contact portion with the drive roller 21 is located at the center in the width direction. Therefore, even if the transport belt 27 is shifted in the width direction, the transport belt 27 immediately returns to an appropriate position and is stabilized at that position. Therefore, meandering of the transport belt 27 hardly occurs. It is desirable that the guide rollers 22, 23, 24, and 25 have the same shape, but in some cases, some of the guide rollers may have different shapes.

Below the end of the butt transport portion 27A,
A butt collection container 30 into which the butts transported by the transport belt 27 are dropped is disposed. The butts collection container 30 is filled with a non-combustible gas, for example, carbon dioxide gas, supplied from a non-combustible gas cylinder 31.
As soon as you enter 0, it is digested. In this manner, when the butts are digested with the non-combustible gas, the disposal of the butts can be performed more sanitarily than the method of storing and digesting water.

One end of an exhaust hose 40 is connected to the duct 6 of the storage table 2 communicating with the inside of each ashtray 4 through a smoke outlet, and the other end of the exhaust hose 40 is connected to a dust filter. It is connected to a blower motor 42 via 41. Further, the blower motor 42 communicates with the outside of the room through an exhaust hose 43. By driving the blower motor 42, the smoke of the cigarette trapped in the ashtray 4 is sucked from the smoke outlet through the duct 6 and the exhaust hose 40, and after the nicotine and tar components are removed by the dust filter 41. Then, the air is discharged outside through the exhaust hose 43. The above-described drive roller 21 and guide rollers 22, 23, 24, 2
5, the groove 50 may be formed along the outer periphery of the central portion as shown in FIG. In this case, the two edges 50a and 50b of the groove 50 come in contact with the conveyor belt 27, and the rotation is transmitted to the conveyor belt 27 through the portion, so that a more stable meandering adjustment function is exhibited.

[0021]

As is apparent from the above description, the automatic butts collecting apparatus according to the present invention has a large diameter at the center in the width direction, such as a driving roller around which an endless belt for conveying butts is wound. By making the diameter gradually smaller toward the outside, the endless belt hardly shifts in the width direction with respect to the roller, and the running of the endless belt is stabilized, so that the endless belt comes into contact with the inner wall surface of the storage table. Troubles caused by being stuck in a gap or the like can be prevented beforehand.
