Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for lifting a pachinko ball, that is, a device for lifting a pachinko ball from a low position to a high position (hereinafter referred to as a "lifting device").

[0002]

2. Description of the Related Art As a known lifting device, there is a lifting device disclosed by the present applicant in Japanese Patent Application Laid-Open No. 11-114199. A conventional lifting device 101 shown in FIG. 10 includes a spiral body 103 having a spiral groove 102 formed on an outer peripheral surface, a lifting tower surrounding the spiral body 103 (not shown in FIG. 10), and introducing a pachinko ball into the spiral groove 102. And a rotating short cylinder 105 for feeding the supplied pachinko balls into the rotating short cylinder 105.
And a throw-in inclined portion 107 disposed around the lower end.

[0003]

Although the above-mentioned conventional lifting apparatus operates well, there is room for improvement in the following points. That is, since the hoisting apparatus 101 is often installed in a limited area within a pachinko machine aggregate called an island in a pachinko game arcade, the area that can be occupied by the loading inclined portion 107 is also limited. Inside the island, a transport device for transporting pachinko balls and a collection device for collecting pachinko balls that have been played are installed, so the depth dimension when this island is viewed from the front is extremely limited. ing. Since the lifting device must be installed in the limited space in the island, the size of each member constituting the lifting device, particularly the depth, is often limited. As a result, the insertion inclined portion 107 for inserting a pachinko ball.
Is greater than the width dimension Lw.

[0004] The injection inclined portion 107 is a rotating short cylindrical body 10.
Since the pachinko balls are to be thrown in from the periphery of the sling 5, it is preferable that the slingshots to be thrown in are thrown into the short cylinder from all directions of the short cylinder 105. However, the depth dimension L
As a result, d is cut off, whereby the input inclined portion 107 is formed in a substantially rectangular shape when viewed in a plan view. When the charging inclined portion 107 is formed in a rectangular shape, the short cylindrical body 107 is formed.
The distance Ls between the outer peripheral surface of the ball and the end of the insertion inclined portion 107 is reduced, and as a result, it becomes difficult for the pachinko ball P to pass through the area indicated by the distance Ls. For this reason, the pachinko ball P supplied from the direction of the arrow A is stagnated as shown in FIG. 10 and cannot be turned to the back side of the short cylinder 105, so that it is not thrown into the short cylinder 105 from the direction of the arrow B. rare. Therefore, the pachinko ball P can be relatively efficiently introduced into the portion of the short cylindrical body 105 facing the arrow A, but almost no pachinko ball P can be introduced into the portion facing the arrow B direction.
Such variation in introduction is due to the efficiency of introduction of pachinko balls,
As a result, there is a possibility that the efficiency of the transportation will be adversely affected. This problem is not limited to the case where the input inclined portion 107 is formed in a rectangular shape, and even if the input inclined portion 107 is formed in a shape other than this shape, an adverse effect on the pumping efficiency is expected to a different extent. It is an object of the present invention to eliminate such an adverse effect on the freight efficiency.

[0005]

Means for Solving the Problems To solve the above-mentioned problems, the inventor of the present invention eliminates the stagnation of the pachinko balls by rotating a part of the throw-in inclined portion, thereby lowering the pumping efficiency.

In the “frying device of claim 4”, the configuration of the freighting device according to any one of claims 1 to 3 is limited, and the length of the charging inclined portion is longer than the diameter of the rotary stirring plate. And a pair of short sides having a length dimension longer than the length dimension of the short side is formed in a substantially rectangular shape in plan view, and the supply of the pachinko ball is performed by any one of the short sides. , From the direction of the injection slope.

According to the fourth aspect of the present invention, in addition to the functions and effects of the first aspect of the present invention, the lifting device has a substantially rectangular shape in plan view. Pachinko balls are supplied from the direction of any short side of the formed slant portion. Since the input inclined portion is formed in a substantially rectangular shape, the depth dimension of the input inclined portion can be made smaller than the width dimension. Thus, the lifting device can be installed even in a narrow area.

The rotary stirrer 19 in the present embodiment is configured to rotate in the same direction as the short cylinder 7 and to rotate at a speed different from the rotation speed of the short cylinder 7. Then, as a result of the relative speed between the rotary stirring plate 19 and the short cylindrical member 7 becoming zero, the relative position of the introduction hole 8 of the short cylindrical member 7 with respect to the pachinko balls on the rotary stirring plate 19 does not change. This is because the pachinko ball cannot be guided to the introduction hole 8. Therefore, the rotation speeds of the two need only be different, and the rotation speed of the rotary stirring plate 19 may be higher than the rotation speed of the short cylinder 7. Further, the rotation direction of the rotary stirring plate 19 may be set to a direction opposite to the rotation direction of the short cylinder 7.

The pachinko ball P introduced into the spiral groove 13 is pumped up by the rotation of the spiral body 11 while the exposed portion is held by the holding member 15, and is discharged from the discharge nozzle 28 of the ball delivery unit 27. On the other hand, the pachinko balls P supplied to the charging inclined portion 17 are stirred by the rotation of the rotary stirring plate 19 and the stagnation is prevented. Further, the pachinko ball P spreads to the back side of the short cylindrical body 7 as shown in FIG. 8 by this stirring, whereby the pachinko ball P is thrown into the short cylindrical body 7 from a direction other than the supply direction. As described above, since the pachinko ball P is supplied to the short cylinder 7 from a direction other than the supply direction, the efficiency of introduction into the short cylinder 7 and, consequently, the lifting efficiency of the lifting device 1 can be improved. .
