TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko ball lifting device installed on an island of a pachinko hall and for lifting a pachinko ball flowing from a ball collection gutter of the island above the island.
[0002]
TECHNICAL BACKGROUND OF THE INVENTION
In this type of pachinko ball lifting device, a pair of upper and lower rollers with an endless belt stretched over a lifting cylinder extending above and below the island are installed, and the pachinko ball received from the lower ball receiving portion is lifted. It is held between the ball guide and the belt cylinder, while polishing the sphere which pumped upward outlet is known by rolling ball by the belt which rotates upward.
[0003]
[Problems to be solved by the invention]
In this apparatus, it is necessary to level the balls flowing from the ball receiving portion and to send them in a line below the lower roller. For this reason, a leveling plate is provided at the receiving part of the ball flowing from the island gutter so that the ball flows in one step to the alignment plate on the bottom of the receiving part, and the ball is placed at the tip of the alignment plate facing the lower side of the lower roller. A delivery guide is provided in which a number of partition plates for aligning in a line are erected in parallel.
[0004]
However, conventionally, since the bottom alignment plate of the receiving part is a flat descending inclined surface, the sphere rolls into disorder, as a result, the sphere from each direction collides with the partition plate of the delivery guide formed at the tip of the alignment plate, Frequently, the partition plate is deformed and the ball passage is closed.
[0005]
Further, in this type of ball lifting device, it is necessary to rotate the rolling belt suspended between the upper and lower rollers around the center of the roller. For this purpose, use a spherical roller with a bulged central part for the upper and lower rollers.However, if a spherical roller is used, the belt will be looser on the left and right than the center of the width, so make sure that the belt has uniform tension over the entire width of the belt. Can not be done. Therefore, the spherical roller is incompatible with the roller of the pachinko ball lifting device which grips and slides the ball between the belt in the lifting cylinder and the vertical ball guide surface, and has to rely on the cylindrical roller. It has been difficult to stably rotate the belt around the center of the roller.
[0006]
Further, in the conventional device, a width adjusting roller is provided between the upper and lower rollers to keep the belt rotating width parallel.However, since the roller has a fixed bearing position, it has a width holding function and has a belt tension. Can not be adjusted. For this reason, in order to adjust the tension of the belt, it is necessary to separately provide a tension adjusting means on the upper and lower rollers.
[0007]
In addition, this type of lifting device interposes a polishing sheet on a part of the ball contact surface of the ball guide and rolls the ball along the polishing sheet surface, thereby lifting the ball while polishing it. is there. In such a ball lifting device, a large number of convex springs press against the back side of the ball guide in order to bring the polishing sheet into elastic contact with the ball.
However, since the elasticity of the convex spring is not planar but local, it cannot provide a uniform elasticity to the entire surface of the ball guide. There is play in the guide. In addition, the convex spring increases the cost.

[0029]
Further, as shown in FIGS. 1 and 3 , the ball lifting device 1 of the present invention forms the rotation width of the lower roller 6 of the lifting cylinder 4 wider than the rotation width of the upper roller 5, and A width adjusting roller 40 is provided above the roller 6 so as to engage with the outer peripheral surface of the rolling belt 7 to maintain a constant (parallel in the drawing) rotation track width of the rolling belt 7. The position of the rotary bearing 40 is moved in parallel along the axial direction of the lifting cylinder, so that the tension of the rolling belt 7 can be adjusted while keeping the width of the rotating track of the rolling belt 7 constant. It is. In this case, the wide roller 6 is not limited to a single roller as shown in the figure, but includes a case where two or more rollers having a small diameter are used and the rotation width is substantially wider than the other roller.
[0030]
FIG. 7 shows a specific example thereof. A vertical opening 42 is formed in the left and right side plates 4a and 4b of the lifting cylinder 4 through the support shaft 41 of the width adjusting roller 40 so as to be vertically movable. Along the vertical edge of 42, a plurality of bearings 43 with which the support shaft 41 of the width adjusting roller 40 is engaged are formed.
[0031]
Thus, when the support shaft 41 of the width adjusting roller 40 is moved downward in accordance with the vertical opening portion 42, the tension of the belt is increased while maintaining the rotation track width, and when the belt is moved upward, the tension is relaxed. Then, the support shaft 41 is engaged with a desired bearing portion 43 to fix the bearing position. In the drawing, a member indicated by reference numeral 44 is a receiving member that locks the bearing position by engaging with the support shaft 41 of the width adjusting roller 40, but is not necessarily required depending on the shape of the bearing portion 43.
[0032]
【effect】
In the lifting device of the present invention, the balls aligned in a row in the concave groove of the ball receiving portion are sent to the vertical groove of the guide plate as they are, so that they do not collide with the passage member and are deformed. Therefore, smooth lifting without clogging is guaranteed.
[0033]
Since the rolling belt is always automatically controlled to the correct position by the convex and concave engagement, there is no possibility that the rolling belt is deflected in the lateral direction even when the cylindrical roller is used up and down.
[0034]
In a polishing section such as a lift, an elastic pressure is applied to the sphere by an elastic plate having a wide flat surface, so that the sphere is polished smoothly. In addition, since this elastic plate can be formed only by perforating the urethane plate, the cost is low and the durability is high.
[0035]
Since the bearing position of the width adjusting roller can be moved in parallel, the belt tension can be adjusted while maintaining the width of the rotation orbit of the rolling belt.
