Description

[Detailed Description of the Invention] Purpose of the Invention (Field of Industrial Application) The present invention is a pachinko ball automatic circulation system in a pachinko game hall, and uses a helical spring as the main mechanism for polishing one pachinko ball and lifting it upward. It's about lifts.

(Prior art) Conventionally, polishing and lifting of pachinko balls are indispensable, and various types of lifts are provided, but the present invention involves a method in which a cylindrical lifting path is set up in an L shape, and a helical spring is placed inside the lifting path. Let it hang freely along the feed path 1, then rotate the helical spring with power at the top ＼ Inject resin particles and pachinko balls at the same time from the bottom inlet and mix them, polishing the pachinko balls with the resin particles. (In the case of lifts that lift objects up to a predetermined height, they are widely used because they have the advantage of having a simple structure and fewer failures.) Pachinko balls between walls are often agitated with resin particles, polished, and transported efficiently; however, pachinko balls that have entered the inner diameter of the same helical spring are less likely to be agitated, and the pressure to push up the resin particles increases. Both polishing and lifting are unstable because the ball moves upward in the lifting path and is pushed out from the ball outlet at the top of the ball.

When the helical spring is polished and lifted, the extension and contraction stroke varies greatly depending on the weight (depending on the amount of the ball entering the lifting path), so the electric motor is attached to the top of the lift. limited to installation. Therefore A
In addition to being difficult to install in places with low ceiling heights in game halls, lifts that protrude above the island look bad, and game hall heating has a negative impact on electric motors that generate heat. do not have.

(Problems to be solved by the invention) In the above-mentioned conventional spiral spring type lift, it is not possible to polish and lift the pachinko balls in an average manner, and because the expansion and contraction stroke of the spiral spring due to the weight of the balls is large, one electric motor is placed at the top of the lift. To solve the problem of installation limitations and to eliminate disadvantages such as unnecessary expansion and contraction fatigue of the helical spring due to the weight of pachinko balls entering the inner diameter of the helical spring and waste of power consumption.

Structure of the Invention (Means for Solving Problems) The present invention provides a blocking body in the inner diameter of the spring in order to prevent unnecessary intrusion of pachinko balls and resin particles into the inner diameter of the spiral spring, and the blocking body is shaped like a pipe or a rod, for example. This is a helical spring type lift in which the body is inserted into the pipe, and a wire is loosely inserted into the pipe. .

, configuration, ' Figure 1 is an overall view of the helical spring type riff) A of the embodiment\1
9 is a lifting cylinder which is formed vertically from the base part 2 with a horizontal bottom surface to an abbreviated shape.The lower part of the lifting cylinder 1 is provided with an inlet lower for receiving pachinko balls and resin particles, and the upper part thereof is an outlet. 9 is formed. A helical spring 3 is rotatably installed in the lifting tube 1 from the power transmission section 8 to the inlet 6 for the pachinko balls and resin particles, along the lifting tube 1. 10 is a separator that separates the pachinko balls and resin particles discharged from the outlet 9 through a drainboard passage, the pachinko balls flow out from the jasper outlet 11 to the destination, and the resin particles flow from the return path 12 to the two-man lower base section. Drop it and wait.

To explain the gist of the present invention in detail, a helical spring 2 shown in FIG.
To describe the guide pipe below the blocker, the guide pipe 4 is loosely inserted into the inner diameter part of the block, and the wire 5 is passed through the same pipe.
Its starting end is connected to the electric motor 6, and its terminal end is connected to the power transmission section 8, so that the rotation of the electric motor 6 simultaneously rotates the helical spring 3 installed on the power transmission section 8 via the wire 5. The guide pipe 4 shown in Fig. 3.4 is not limited to being made of metal or resin, but may be made of any material with high durability and productivity. etc. may be filled in.

Furthermore, even when only the guide pipe 4 is installed in a conventional spiral spring type lift, the effects described below can be obtained.
In this case, it can be widely used by changing the design, such as installing the guide nozzles 4 at intervals or fixing a part of the guide nozzles 4 to the helical spring 3.

(Function) To explain the present invention in detail, as the electric motor 6 rotates, the wire 5 is interlocked and the helical spring 3 installed on the power transmission section 8 on the upper part of the lifting cylinder 1 of Riff) A is driven. Then, the pachinko balls and the return path 1 are passed from the input lower provided on the base 2.
The pachinko balls are mixed with the resin particles waiting in step 2 by 30 revolutions of the helical spring and moved up the lifting path shown in FIG. Then, the jasper balls and the resin particles are separated by the separator 10, and the resin particles fall into the return conveyor @ 12, and together with the pachinko balls, they go up the transport path B again and are subjected to one repetition.

In this case, since the guide pipe 4 is loosely inserted into the inner diameter of the helical spring 3 (in the lifting path B), pachinko balls and resin particles cannot enter, and the helical spring 3 is lifted with the helical spring 3 located approximately at the center. Since feed polishing is performed, the amount of resin particles used is small and the lifting speed of one pachinko ball is increased.
Furthermore, the load on the helical spring 3 due to the weight of the pachinko ball is also reduced.

Effects of the Invention According to the present invention, the useless area of the lifting path of the lift is eliminated and the effective area is limited to the circumferential part of one helical spring, so that the grinding and lifting of pachinko balls are equalized, the lift is accelerated, and the mission of one lift is achieved. enhance Second, by polishing the helical spring and reducing the load caused by the weight of the pachinko ball during lifting, it is possible to extend the life of the ball due to expansion and contraction fatigue.
Thirdly, by using a guide pipe to measure power transmission by wire, we installed an electric motor at the bottom of the base, which was previously impossible, to minimize vibrations per lift and stabilize the center of gravity. It has many features, such as reducing the amount of circulation, fourth, reducing power consumption, and fifth, simplifying the structure, which enhances the conventional advantages of helical springs without sacrificing them, making maintenance easier.
