Description

  The present invention relates to a ball lifting device for a pachinko machine for lifting a pachinko ball to an upper part of the gaming machine island or a launch position in the gaming machine.

Pachinko machines are arranged with a plurality of pachinko machines forming one gaming machine island, and the balls circulate in the gaming machine islands and between gaming machine islands. Usually, a ball lifting device is arranged at the end of the gaming machine island, and the balls collected after being used are polished and then transferred to the upper part of the gaming machine island by the ball lifting device. Provided for use.
In addition, in a sealed pachinko machine, the ball circulates in one pachinko machine. Normally, a lifting device is provided in the enclosed pachinko machine, and the balls collected after the launch are transported to the launching device by the ball lifting device and are again used for launching.

  Examples of the ball lifting device are disclosed in Patent Documents 1 and 2. These have a helical coil, and a ball taken in between the pitches of the helical coil can be guided and lifted by a pachinko ball moving guide member. However, since the spiral coil is wound at a constant pitch, when the ball is lifted at a high speed, the load applied to the drive source increases, and the ball is caught at the ball entrance and exit of the guide member. There was a problem that it was not possible to smoothly receive and send out the sphere. In addition, since the spheres are held for each pitch of the spiral coil at a constant interval, there is a problem that the number of spheres in the lifted state increases and the required number of the entire spheres increases.

  In view of the above-described conventional problems, the present invention is a pachinko machine that can lift a ball at a high speed with one rotation of a spiral coil in an intermediate portion, and can smoothly receive and send a ball. It is an object to provide a ball lifting device.

A ball lifting device for a pachinko machine according to the present invention, which has been made to solve the above-described problems, includes a rotating body that is rotated by a driving source and lifts the ball, and the rotating body is incorporated to guide the ball upward. In a ball lifting device of a gaming machine comprising a guide cylinder that
The rotating body is made into a rod-like shape in which a spiral groove is formed between spiral ridges, and the pitch of the spiral ridges at both ends of the rotating body is smaller than the intermediate part, The ball lifting speed in is lower than the middle part.

  In the above-described invention, a metal wire is spirally wound around a rod-shaped guide shaft to form a spiral crest, and a spiral groove is formed between the spiral crests. A pitch can be formed smaller than an intermediate part, and the ball | bowl lifting speed in the both ends of a rotary body can be made smaller than an intermediate part. In addition, one guide can be provided in the guide tube so that each ball can pass vertically, or a ball can be passed through the guide tube so that each ball can pass vertically. Two or more paths can be provided.

  In the ball lifting device of the pachinko machine of the present invention, the pitch of the spiral crests at both ends of the rod-shaped rotating body is smaller than the middle portion, so that the ball feeding speed at both ends is reduced and the balls are received. And can be delivered smoothly. In addition, since the pitch of the spiral crest portion in the intermediate portion is larger than the both end portions, it is possible to increase the amount of movement of the sphere by one rotation of the rotating body, and thereby the sphere is lifted at high speed in the intermediate portion. be able to. In addition, when the speed of ball lifting by the rotating body is set to low speed or high speed, the pitch of the spiral peak portion of the metal wire wound around the rod-shaped guide shaft is partially narrowed or distant so that one spiral The ball speed can be freely adjusted by one rotation of the coil.

It is a front view which shows the internal structure of the ball lifting apparatus of this invention. It is a side view of the ball lifting device of FIG. It is a principal part enlarged view of a spiral coil. It is a principal part enlarged view of a spiral coil. It is the top view (a) which shows the ball lifting apparatus of another form, and front sectional drawing (b).

Hereinafter, embodiments of the present invention will be described.
1 and 2 are diagrams showing a ball lifting device of a pachinko machine according to a first embodiment, wherein 1 is a motor as a driving device, 2 is a rotating body, and 3 is a guide tube for ball lifting. is there.

  The guide tube 3 has a sphere inlet 31 for receiving spheres one by one at the lower end and a sphere outlet 32 at the upper end. The bottom surface of the sphere entrance 31 is formed in a downward slope to facilitate the taking-in of the sphere, and the ceiling surface of the sphere exit 32 is curved toward the opening to facilitate the discharge of the sphere (FIG. 2). In the lifting device shown in FIG. 1, the rotating body 2 is erected on one side of the guide tube 3, and thereby the balls pass along one side surface 33 of the guide tube 3 in a vertical row. A possible ball lifting path 6 is formed.

  The rotating body 2 includes a rod-shaped guide shaft 5, a spiral coil 4 in which a metal wire is spirally wound outside the guide shaft, and a spiral coil support gear 51. A spiral coil support gear 51 is provided at the lower end of the guide shaft 5, and this spiral coil support gear 51 is engaged with the motor gear 11. The upper end of the guide shaft 5 is held by a bearing (not shown) provided on the guide cylinder 3. As the guide shaft 5, it is desirable to use a metal rod such as steel or stainless steel having excellent wear resistance and rigidity. Further, as the helical coil 4, a metal wire such as a hard steel wire, a stainless steel wire, or a piano wire can be used.

  In the rotating body 2, the spiral coil 4 is formed as a spiral mountain portion, and a spiral groove 42 is formed between the spiral coils 4. As the rotating body 2, a rod-shaped guide shaft 5 and a spiral crest can be integrally formed, and a drill having a spiral groove formed between the pitches of the spiral crest can be used.

  The guide tube 3 may be a metal tube having a square shape, a circular shape, an oval shape, or the like. The ball lifting device configured as described above is fixed to the back surface of the gaming machine by the mounting member 7 or other mounting methods (direct mounting, fitting, etc.).

  Note that, in the ball transporting path 6, a gap between the side surface 33 of the ball transporting path 6 and the outer peripheral surface of the guide shaft of the rotating body 2 is formed so that a single row of balls can pass therethrough. A small gap is formed between the outer periphery of the spiral coil so that one sphere does not fall off.

  The principal part structure of the helical coil 4 is shown in FIG. The spiral coil 4 has a linear portion 41 at the lower end thereof, and is fitted and attached to a groove portion of a spiral coil support gear 51 (not shown). Further, it is possible to fix the spiral coil 4 by tightly winding it around the guide shaft 5 at the lower end. The lower end portion of the spiral coil 4 has a pitch P1 narrowed to form a slightly wider pitch P2, and further to a next wider pitch P3, around which the spiral coil 4 is wound. For example, P1 can be set to 30 mm, P2 to 50 mm, and P3 to 100 mm. On the contrary, the structure of the upper end portion of the spiral coil 4 is formed so as to become narrower sequentially as P3, P2, and P1. Since the spheres are taken in and raised between the pitches, the spheres can be slowly received from the sphere entrance 31 and the received spheres can be gradually increased and transported. And since the pitch is formed narrowly at the upper end, the balls that have been pumped at a high speed can be sequentially decelerated and sent out from the ball outlet 32 at a low speed. Further, when it is desired to change the lifting speed, the lifting speed can be freely controlled by making the required portion of the coil pitch variable freely.

  Further, as shown in FIG. 4, the winding of the spiral coil 4 can be continuously repeated after the short pitch P <b> 1 and the long pitch P <b> 2. For example, P1 can be set to 30 mm and P2 can be set to 100 mm. Even if the spiral coil 4 is configured as described above, the ball received from the ball entrance 31 at a low speed is rapidly increased and then lifted, and then immediately decelerated immediately before the ball exit 32 and sent at a low speed. Can do.

  FIG. 5 shows the guide cylinder 3 provided with two ball lifting paths 6. That is, since the guide cylinder 3 has a rectangular cross-sectional shape and the rotating body 2 is erected at the center of the guide cylinder 3, the ball lifting path 6 can be provided between the rectangular short side surface 33 and the ball lifting path 6. It is possible to double the lifting capacity of the ball with two. Furthermore, four guides 3 can be provided by expanding the guide cylinder 3 in four directions to form a cruciform shape, and by increasing the diameter of the guide shaft 5, the guide shaft 5 A large number of ball pumping paths 6 can be provided on the outer periphery of.
