Description

[Detailed Description of the Invention] The present invention relates to a pachinko ball polishing and ball lifting machine suitable for installation on each island within a pachinko game parlor.

Conventional pachinko ball polishing equipment led all the pachinko balls from all stores to the basement, polished them intensively, and then lifted them to the ceiling using a large lift, and supplied the pachinko balls to each island in the store via a distribution device. Not only did the ball polishing machine and the ball lifting machine become larger, but the pachinko ball supplementary ball system also had the disadvantage of requiring a large amount of equipment cost.

Conventionally, a linear helical body whose one end is connected to a motor to be rotated is bent and inserted into a polishing cylinder that is bent in an arc shape and extends upward, and pachinko balls and polishing machines are inserted into this polishing cylinder. A device that uses grains to polish and lift pachinko balls has also been put into practical use, but since it is necessary to insert a single helical body into a bent polishing cylinder, it is necessary to bend the helical body used. It needs to be relatively soft and therefore relatively low in rigidity. Therefore, when a large load is applied to the helical body when the polishing cylinder is full of pachinko balls and abrasive grains, the helical body may be damaged.

At the same time, since one helical body is driven by one motor, if there are many pachinko balls etc. in the polishing cylinder when the device is started, a large load will be placed on the motor and the steady It was necessary to use a motor with an excessive capacity compared to the motor capacity required in the driving state. Furthermore, a helical body whose upper end is connected to the motor and whose lower end is a free end protruding downward from the lower end opening of the lifting pipe is inserted into the vertical lifting pipe, and the spiral body is inserted into the vertical lifting pipe. A ball storage section is installed to store the pachinko balls that fall from the pachinko ball collection gutter, and the pachinko balls and abrasive material piled up in the ball storage section are lifted into the lifting pipe by the rotation of the helical body. In addition, an apparatus has been proposed which polishes pachinko balls while lifting them along this lifting pipe (Japanese Patent Laid-Open No. 139376/1983).

According to this proposal, there is no need to bend the helical body, so there is no problem as described above, but the helical body protruding from the lower end opening of the lift pipe
In order to lift the pachinko balls that are normally stacked free and unrestricted in the ball storage section, the helical body at the lower end should be shaped like a gill or screw with a predetermined surface rather than a linear shape. It is necessary to scoop up the pachinko balls and introduce them into the transport pipe. Therefore, the helical body in this proposal cannot actually perform its function unless the linear helical body in the lift pipe and the screw body near the lower end protrusion are connected. .

This not only increases the manufacturing cost of the helical body compared to the above-mentioned device in which a uniform helical body is bent into an arc shape and is inserted into the polishing cylinder, but also the manufacturing cost of the helical body is higher than that of the device that bends the uniform helical body into an arc shape and inserts it into the polishing cylinder. The parts that connect to the body inevitably pose problems in terms of strength, which can lead to failures.

Conventionally, screw-shaped fins are supported at both ends of L-shaped cylinders consisting of horizontal and vertical cylinders, and pachinko balls and polishing media are housed inside the cylinders. Some machines are designed to polish the ball when it is played, but when using a rigid screw-shaped fin body supported at both ends, the fin body has no "relief" and there is no chance that a pachinko ball, etc. will fall into the cylinder. In order to create a configuration in which the fin body does not break when it is full, it is not only necessary to make the fin body considerably strong, but it also has the disadvantage of being difficult and extremely expensive to manufacture. .

The purpose of this invention is to form a pachinko ball circulation loop for each island, and to create a pachinko ball polishing and lifting machine that is suitable for use within the circulation loop, and which has a structure that is better than the conventional one described above. A pachinko machine that is simple and easy to manufacture, has a long lifespan without breaking down even when a large number of pachinko balls are supplied, and is capable of stable operation at all times, with the motor load at startup not much different from that during steady operation. Our goal is to provide ball rolling machines.

Hereinafter, embodiments of the present invention will be described based on the drawings.

The transfer pipe 1 has an L-shape in which one end of the horizontal transfer pipe 2 and the lower end of the vertical transfer pipe 3 communicate at a communication point A, and has a circular cross section. A motor 4 is provided at the other end of the horizontal transfer pipe 2, the output shaft 5 of which projects into the transfer pipe, and a first linear helical body that penetrates the horizontal transfer pipe 2 to the communication point A. 6 is supported at one end. The other end of this first linear helical body 6 is a free end as shown in the figure.

A motor 8 is installed on a frame 7 provided at the upper end of the vertical transfer pipe 3. This motor 8 is connected to the input shaft of a gear box 9 containing a worm gear or bevel gear, and the output shaft 10 of this gear box 9 is vertically connected. It protrudes into the inside of the transfer tube 3 from the upper end thereof. One end of a second linear helical body 11 is supported by this output shaft 10 . The other end of the second linear helical body 11 reaches the communication point A, and is a free end as shown.

The outer diameters of the first and second linear helical bodies 6 and 11 are both d, and the inner diameters of the horizontal and vertical transfer pipes 2 and 3 are both D,
The gap size (D-d)/2 between these is selected to be larger than the diameter size of the pachinko ball.

A pachinko ball input port 12 and an abrasive material input port 13 are opened above the end of the horizontal transfer pipe 2. Further, a discharge port 14 is opened at the upper end of the vertical transfer pipe 3, and a separation device 15 for separating the discharged pachinko balls and the abrasive material is provided. The abrasives separated here are returned to the abrasive inlet 13 via the pipe 16. The separating device 15 is configured such that, for example, when pachinko balls roll on a screen stretched at an angle, the abrasive material falls down from the screen.

As the abrasive material, strips or granules of materials such as leather, artificial leather, and plastic that are softer than pachinko balls and easily absorb dirt are used.

In the above embodiment of the present invention, the L-shaped transfer pipe 1
Pachinko balls to be polished and abrasive materials are mixed and stored inside until it is almost full.

When the motors 4 and 8 are driven in this state, the first and second linear helical bodies 6 and 1
1 rotates to convey pachinko balls and abrasive material in the direction of the arrow in the figure, and after these are discharged from the discharge port 14, they are separated into pachinko balls and abrasive material by a separation device 15, and the pachinko balls are replenished. Gutter (not shown)
The abrasive material is supplied to each pachinko game machine through the pipe 16 and returned to the input port 13 for reuse.

Here, the mechanism by which pachinko balls are transferred along the vertical transfer pipe 3 by the rotation of the linear second helical body 11 is as follows. First helical body 6
Due to the rotation of the horizontal transfer tube 2, a large number of pachinko balls are pressed against the lower end portion of the vertical transfer tube 3. In this state, each pachinko ball is pressed from behind at the lower end portion of the second helical body 11 and is restrained relative to each other. When the second helical body 11 is rotated in this state, the pachinko balls in that area will be affected by the pressing force by the first helical body 6 even if the lifting force due to the rotation of the second helical body 11 is small. It moves upward in the vertical transfer tube 3 due to the interaction between the two. Therefore, even if only the second helical body 11 is rotated without rotating the first helical body 6, the pachinko ball will not be lifted.
This means that the second helical body 11 will be explained later.
This leads to the effect of reducing the load when starting the motor 8 that drives the motor 8.

Note that a plurality of ball input ports 12 may be provided at the tip and center of the horizontal transfer pipe 2, etc.

As explained above, according to the present invention, the transfer pipe is connected to the L where the horizontal transfer pipe and the vertical transfer pipe are orthogonal to each other and communicate with each other.
Because it is shaped like a letter, it is easier to manufacture than the conventional transfer tube that is curved in an arc.
Moreover, the installation work is easy, and furthermore, the space under the pachinko game machine, around the pillars of the building, etc. can be effectively used for installation. Additionally, if there are a large number of pachinko machines installed on one island, the horizontal transfer pipe can be lengthened to provide multiple pachinko ball input ports, and a pachinko ball collection gutter can be installed for each ball input port. Therefore, it is possible to maintain the slope of each collection gutter at a required slope, and it is possible to maintain a smooth flow of pachinko balls.

In addition, in the present invention, the first and second linear helical bodies are provided in the horizontal transfer pipe and the vertical transfer pipe, respectively, which are rotationally driven by separate motors. Since there is no need to bend the helical body as in the case of a ball machine and ball-lifting machine which is provided with a helical body, a linear helical body with relatively high rigidity can be used. Moreover, since the tips of the first and second linear helical bodies are made free ends, the wires rotate while flexing appropriately and escaping from the pachinko balls and abrasive material that fill the transfer pipe during rotation. In addition to the fact that extreme loads are no longer applied to the linear helical body and it is possible to use a linear helical body with relatively high rigidity as mentioned above,
Problems such as damage to the helical body can be significantly reduced. Furthermore, in the present invention, the first
The helical body presses the pachinko balls against the lower end of the vertical transfer pipe, and the second helical body is rotated while in this pressed state to lift the pachinko balls, so each helical body is placed in a uniform line. The lower end of the vertical helical body does not need to be a screw body with a surface for lifting the pachinko balls, as in conventional proposals, and the manufacturing cost can be kept low. In addition, since there are no weak points such as connecting parts, the frequency of failures can be significantly reduced.

At the same time, driving the first and second linear helical bodies with separate motors has the following two advantages.

One of them is that horizontal and vertical transfer generally differ in the power required for transfer or the number of rotations of the linear helical body required to obtain a certain transfer speed. By providing a linear helical body and a motor to drive each,
Each can be adjusted to optimal conditions.

Another advantage is that it is possible to prevent a large load from being applied to the motor when starting up the device. In other words, when the device is started up and there are many pachinko balls and polishing media in the transfer tube, a large load is placed on the linear helical body for vertical transfer, which is caused by
This is because the pachinko balls in the pipe must be launched and launched at the same time. On the other hand, in order to transfer the pachinko balls in the vertical direction, the pachinko balls must be pushed into the lower entrance of the vertical transfer pipe with a predetermined force. Therefore, when starting up the device, the horizontal linear helical body is not driven, and only the vertical linear helical body is first driven. As a result, although the vertical linear helical body rotates, it is unable to lift the ball, and the load on the motor at the time of starting is reduced. All you have to do is start the horizontal linear helical body in this state, and the load that acts on the motor that drives the vertical linear helical body at the time of activation can essentially be divided into two parts. It is. As a result, it is not necessary to increase the capacity of the motor so much as compared to the steady driving state, and an excessive load is not applied to the linear helical body, which is advantageous in terms of the life of the device.

As mentioned above, when the vertical helical body is driven without driving the horizontal helical body, in order for the vertical helical body to rotate but not to lift the ball, this helical body must be must be linear, and if a screw-shaped fin body is used, such an effect cannot be achieved.
