The pachinko machine (not shown) is provided at an appropriate position (often at one end or the center) of the pachinko island B where the pachinko machines (not shown) are lined up in the lateral direction. Below the pachinko island B, a collection path C for collecting the pachinko balls discharged from the pachinko machine is provided in an inclined manner.
Further, a distribution path E for distributing the pachinko balls as prize balls to the respective pachinko machines is provided on the upper side in an inclined manner.
Then, the lifting device A is arranged between the lower end of the recovery path C and the upstream end of the distribution path E, and the pachinko balls recovered on the recovery path C are raised while being polished and discharged to the distribution path E. It is supposed to be done.

By the way, the lifting device A is substantially covered with a cylindrical protective cover A1, and inside thereof, as shown in FIG. 7, an upper roller A2 arranged at an upper part and a lower part arranged at a lower part are arranged. A conveyor belt A4, which is a leather endless belt, is built in between the roller A3 and the roller A3. Further, the driven pulley A is attached to the rotary shaft A5 of the lower roller A3.
6 is integrally fixed, and the driven pulley A6 is fixed to the motor shaft of the drive motor A8, but is connected to the drive pulley A9 via the V belt A7. Therefore, the lifting device A
Rotates the lower roller A3 by transmitting the rotational force of the drive motor A8 through the V-belt A7, thereby rotating the conveyor belt A4. When the conveyor belt A4 rotates, the pachinko ball is pushed upward by the frictional force between the conveyor belt A4 and the pachinko ball. At this time, since a polishing cloth is provided at a position facing the transport belt A4, the pachinko ball is polished at the same time as it moves up. In addition,
Between the upper roller A2 and the lower roller A3, an adjusting roller A10 for constantly applying tension to the conveyor belt A4.
Is provided.

The lifting device A having the above-described configuration is a support plate A made of metal.
The support plate A11 is fixed on the fixed base 11, and is fixed to the fixed base A12 fixed by anchor bolts so as to be slidable in the front-rear direction. In addition, a storage opening D is opened in the lower part of the pachinko island B so that a simple failure or the like of the lifting device A can be immediately corrected.
Further, when a complicated failure occurs, or when the polishing cloth is replaced, the support plate A11 is slid toward the front side, and the lifting device A is taken out from the pachinko island B to be fixed again. . Of course, at this time, the pachinko island B corresponding to the upright portion of the lifting device A is openable.

[Problems to be Solved by the Invention] In the above-described conventional lifting device A, since the lower drive mechanism portion is complicated and is large, the proportion of the pachinko island B in the lower space is large. In addition, when carrying out maintenance and repair, there is a problem that, for example, replacement work of the conveyor belt A4, tension adjustment work of the V-belt A7, and the like are troublesome.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a pachinko ball lifting device having a small occupied volume, with a simple structure of a drive mechanism that can be easily maintained and repaired. To provide.

[Means for Solving the Problems] In order to achieve the above-mentioned object, a pachinko ball lifting device according to the present invention lifts a pachinko ball by a conveyor belt that is stretched over rollers arranged at an upper portion and a lower portion. It is characterized in that the lower roller is a motor pulley with a built-in drive source, and the supporting shaft of the motor pulley is detachably fixed to the supporting portion.

[Operation] Since the lower roller is directly rotated by the drive source incorporated therein, the conveyor belt is also rotated by the rotation of the lower roller, and the pachinko ball is lifted.
Further, since only the supporting portion that supports the lower roller interferes when removing the conveyor belt that is stretched over the lower roller, if the supporting portion and the supporting shaft of the lower roller can be detached, The conveyor belt can be easily removed and replaced.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings. In Fig. 1, a lifting device 20 according to an embodiment is a pachinko island 43.
It is a side view of the state arrange | positioned at. In the figure, the lifting device 20 is covered on its front and rear surfaces and one side surface by a cylindrical protective cover 21 which is long in the vertical direction, and the other side surface (a surface facing a surface on which a conveyor belt 26 described later moves upward).
A polishing cloth storage cover 22 that stores a polishing cloth for polishing a pachinko ball is attached to the openable and closable. Although not shown, the polishing cloth storage cover 22 is formed with a plurality of semicircular grooves for accommodating the pachinko balls in a row. The polishing cloth is accommodated in the grooves and the pachinko balls are rubbed to polish the balls. Is done. Further, since the polishing cloth is arranged in a roll shape on the upper side and the tip thereof is configured to pass through the inside of the polishing cloth storage cover 22 and be wound downward, a predetermined time (for example, one business day) ), The dirty part is wound up, and the clean part corresponds to the conveyor belt 26, so that the ball polishing can always be performed accurately. For this reason, when all the polishing cloths have been used, it is necessary to replace them with new polishing cloths. This replacement work requires the lifting device 20 to move to the pachinko island 4
After pulling it out from 3, the polishing cloth storage cover 22 is opened. The polishing cloth storage cover 22 is locked by the stoppers 23a and 23b in a normal use state.

As shown in FIG. 2, the internal structure of the lifting device 20 is such that an upper roller 24 is rotatably supported on an upper part thereof and a lower roller 25 is rotatably supported on a lower part thereof. The endless conveyor belt 2 is provided between the upper roller 24 and the lower roller 25.
6 has been passed over. In the case of the illustrated embodiment, the conveyor belt 26 is stretched across two rows (see FIG. 4) so that a large amount of pachinko balls can be lifted. Also,
An adjusting roller 27 is arranged near the upper portion of the lower roller 25 so as to contact the conveyor belt 26. Adjusting roller 27
An adjusting spring 28 is provided on the support rod for supporting the conveyor belt 26. Since the adjusting spring 28 constantly presses the conveyor belt 26 inward, the conveyor belt 26 maintains a tensioned state. Then, the conveyor belt 26 and the polishing cloth storage cover 22.
While holding the pachinko ball with, the pachinko ball is moved upward by the frictional force of the transport belt 26.

By the way, a drive mechanism that applies a rotational force to the conveyor belt 26 is built in the lower roller 25. Here, the structure of the lower roller 25 will be described with reference to the sectional view of FIG. 5. The lower roller 25 is a so-called motor pulley, and a drive pulley 30 is rotatably supported by a support shaft 29. . A stator case 31 is fixed inside the support shaft 29, and a stator 32 having a coil wire wound around the outer circumference of the stator case 31 is fixed. On the other hand, in the center of the stator case 31, the rotor shaft 34
Is rotatably supported, and a rotor 33 around which a coil wire is wound is provided around the rotor shaft 34 so as to face the stator 32. That is, the drive pulley 30
When a normal drive motor is placed inside and the power is supplied, the rotor 33 rotates. The pinion gear 35a is attached to one end of the rotor shaft 34.
Is formed, and the pinion gear 35a has a gear gear 35b.
Are engaged. The gear gear 35b is rotatably supported by the stator case 31, and a pinion gear 35c is formed at the tip of the rotation shaft. The pinion gear 35c is adapted to engage with the internal gear 35d formed on the inner side of one side of the drive pulley 30.

Since the lower roller 25 (motor pulley) has the above-mentioned structure, it is electrically energized and the stator 32 and the rotor 33 are rotated.
The rotor shaft 34 rotates due to the repulsion of the pinion gear 35a, the gear gear 35b, and the pinion gear 3
5c and the internal gear 35d are transmitted to the drive pulley 30 to rotate the drive pulley 30. Therefore, the conveyor belt 26 hung on the outer circumference of the drive pulley 30 is adapted to rotate. The support shaft 29 of the lower roller 25 is fixedly supported by a support member 45 as shown in FIG. 4, but the support member 45 is necessary because the conveyor belt 26, which is an endless belt, needs to be replaced.
The support shaft 29 and the support shaft 29 are configured to be removable.

In addition, as shown in FIG. 3, an alignment gutter 37 connected to the recovery path 36 is arranged in the rotational intrusion direction of the lower roller 25, and a bending gutter 38 is arranged continuously to the alignment gutter 37. The polishing cloth storage cover 22 is attached to the tip of the bending trough 38.
The lower end of is connected. These alignment gutter 37 and bent gutter 38
Is for aligning pachinko balls so as to be continuous with the plurality of grooves formed on the front surface of the polishing cloth storage cover 22. (See FIG. 4) Each component of the above-mentioned lifting device 20 is fixed on a metal support plate 39, and this support plate 39 slides in the front-rear direction with respect to a fixed base 40 fixed by anchor bolts. It is fixed freely. The support plate 39 has a first
As shown in the figure, a protective cover 41 for protecting the lower roller 25 is detachably provided. In FIG. 1, a distribution path 42 is connected to the upper portion of the lifting device 20 and a storage opening 44 is formed in the lower portion of the pachinko island 43, as in the conventional case.

The configuration of the lifting device 20 according to the embodiment has been described in detail above. However, since the drive mechanism portion of the lifting device 20 is built in the lower roller 25, it is driven as compared with the conventional lifting device A. Pulley A6, V belt A7, and drive motor A8
Since the structure is simplified without any need and the size in the lateral direction is extremely small, the occupied volume inside the pachinko island 43 can be reduced and the internal space of the pachinko island 43 can be effectively used. Further, since the structure is simplified, in the case of a simple failure, for example, when the alignment gutter 37 causes a ball jam, the hands can be easily inserted from the storage opening 44, and there are no obstructive parts. With very few, the task is extremely easy and easy. In addition, since there is no connection by the V-belt as compared with the conventional one, it is not necessary to constantly adjust the tension of the V-belt.
Furthermore, when a complicated failure occurs or when the conveyor belt 26 or the polishing cloth is replaced, the support plate 39 is pulled to the front side and pulled out from the pachinko island 43, and then the defective portion is repaired. The polishing cloth storage cover 22 may be opened to replace the polishing cloth, or the support shaft 45 may be removed from the support member 45 to replace the conveyor belt 26. In particular, the work of replacing the conveyor belt 26 and the maintenance work for a failure in the vicinity of the lower roller 25 are significantly easier and less troublesome than the conventional work.

The structure of the motor pulley shown in the above-described embodiment is an example, and the structure is not limited to the illustrated structure. In short, any structure may be used as long as the drive source is built in the lower roller.

[Effects of the Invention] As is clear from the above description, the pachinko ball lifting device according to the present invention lifts the pachinko balls by the conveyor belts that are wound around the rollers arranged at the upper and lower portions. In addition, since the lower roller is a motor pulley with a built-in drive source, the structure is extremely simplified and the occupied volume inside the pachinko island can be reduced, so that the internal space can be effectively used and the drive can be performed. This has an excellent effect that the maintenance and inspection of the mechanism can be facilitated, and further, the work of exchanging the conveyor belt and the repair work for a failure near the drive mechanism can be performed very easily and easily.
