Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a relay lift for lifting pachinko balls discharged from a stock tank for storing pachinko balls in a pachinko island on a slope to be supplied to a lifting device.

[0002]

2. Description of the Related Art Conventionally, as relay lifts for pachinko balls, Japanese Utility Model Laid-Open No. 57-120079 and Japanese Utility Model Laid-Open
As shown in JP-A-200777, an endless conveyor belt is stretched around rotating drums arranged vertically, and pachinko balls are accommodated in buckets provided at predetermined intervals on the conveyor belt. By circulating the belt, the bucket accommodating the pachinko balls is moved to an upper position, and the pachinko balls are discharged from the bucket to carry out the lifting.

[0003]

However, these conventional relay lifts have a structure in which pachinko balls are accommodated in the bucket on the lower side and the pachinko balls are discharged from the bucket on the upper side. It takes a certain amount of time to store and discharge pachinko balls in the down stream, so if the circulation speed of the conveyor belt is increased, it will hinder the storage and discharge of pachinko balls. Therefore, the circulation speed has an upper limit, and the buckets are arranged at predetermined intervals, and the pachinko balls are intermittently pumped. There is a problem that the relay capacity must be improved by arranging a plurality of relay lifts.

In these conventional relay lifts, pachinko balls may spill out of the bucket, and the spilled pachinko balls may bite in the conveyor belt, making it impossible to lift the pachinko balls.
In order to carry out storage and discharge in the bucket, it is necessary to carry out lifting on one side of the relay lift, and the pachinko balls to be lifted cannot be discharged to the opposite side of the relay lift. There was also a problem that the method was limited, and it was difficult to relay pachinko balls smoothly.

[0005] The present invention has been made in view of the above-mentioned problems, and is intended to achieve a high lifting capacity, and to provide a smooth relay without causing any trouble such as ball biting. The purpose is to provide a relay lift for pachinko balls that can be used.

[0006]

SUMMARY OF THE INVENTION In order to solve the above problems, a pachinko ball relay lift of the present invention uses a pachinko ball discharged from a stock tank for storing pachinko balls arranged inside a pachinko island. A pachinko ball relay lift for lifting on a supply ramp guided to a lifting device, wherein a pachinko ball inlet is provided on an inclined upper surface at a lower position, and a pachinko ball outlet is provided on an inclined lower surface at an upper position. A helical ridge having both ends provided coaxially with the cylindrical case and having an outer diameter slightly smaller than the inner diameter of the cylindrical case, provided inside the cylindrical case arranged with a predetermined inclination. Are provided, and a drive motor for rotating the screw rotor is provided. According to this feature, the pachinko ball is introduced into the cylindrical case from the introduction port without using a bucket as in the related art, and is continuously transferred upward by the rotation of the screw rotor and discharged from the discharge port. It is possible to eliminate the time to be accommodated in the bucket and discharged, and to easily obtain a high lifting capacity by increasing the rotation of the screw rotor. A mechanism for supplying pachinko balls to the plurality of relay lifts can be eliminated, and a large space is not occupied in a narrow pachinko island. Also, since the pachinko balls are transported in a state housed in the cylindrical case, the balls spill,
Smooth unloading can be performed without causing any trouble due to ball biting and without changing the transfer direction to the linear direction side with respect to the inflow direction of the pachinko balls.

In the relay lift for pachinko balls of the present invention, it is preferable that the inclination angle of the cylindrical case is in a range of 20 to 65 degrees with respect to a horizontal plane. If you do this,
The angle of inflow of the pachinko balls into the inlet, which is substantially perpendicular to the axis of the cylindrical case, can be 25 to 80 degrees, and the amount of pachinko balls flowing under natural flow into the cylindrical case can be sufficiently ensured. In addition, not only can the pachinko balls be dropped inside the cylindrical case without being appropriately dropped, but also the length of the cylindrical case required for lifting the pachinko balls to a predetermined height position is appropriately shortened. It is possible to carry out efficient freight.

In the pachinko ball relay lift according to the present invention, it is preferable that an inlet and / or an outlet provided in the cylindrical case have a polygonal shape. In this way, appropriate gaps are provided between the pachinko balls flowing in and out of the inlet and the outlet, and the occurrence of clogging at the inlet and the outlet is significantly reduced. can do.

In the relay lift for pachinko balls according to the present invention, the opening length of the inlet in the vertical direction of the cylindrical case is 2.5 times the diameter of the pachinko balls, and the spiral ridge provided on the screw rotor is provided. It is preferable that the pitch is set to a range of 0.9 times the pitch interval of the portions. With this configuration, not only can the pachinko balls efficiently flow into the cylindrical case, but also the pachinko balls can be prevented from being bitten at the inlet portion.

[0010] In the pachinko ball relay lift of the present invention, it is preferable that a transmission means such as a gear for transmitting the driving motor rotational force to the screw rotor is provided at an upper end of the cylindrical case. With this configuration, the inlet can be arranged at a lower position of the cylindrical case, and the height position of the ramp and the position of the stock tank discharge portion communicating with the inlet can be similarly reduced. Therefore, the limited height of the lower part of the pachinko stand on the pachinko island can be effectively utilized.

The relay lift 6 for pachinko balls of the present embodiment is
As shown in FIG. 1, a plurality of pachinko machines 2 are arranged on the lower side of the pachinko island 1 in which the pachinko machines 2 are juxtaposed. The counted pachinko balls discharged from the counted machine 3 are stored in the stock tank 4, and the pachinko balls discharged from the stock tank 4 and flowing in through the ramp 5 are supplied to the lifting device 9. The pachinko balls pumped on the supply ramp 7 are fed by the lifting device 9 through the supply guide 8.
The pachinko machine 1 is fed to a supply tank 10 disposed at an upper position of the pachinko island 1 and supplied from the supply tank 10 to each of the pachinko machines 2 and a machine for lending between machines, and circulates.

The relay lift 6 for pachinko balls of this embodiment is
The lower part of the cylindrical case 11, which has the appearance as shown in FIG. 2 and is arranged at an angle of about 54 degrees with respect to the horizontal plane, communicates with the ramp 5 and is supplied from the ramp 5. A square introduction port 12 for introducing a pachinko ball into the cylindrical case 11 is provided on the inclined upper surface side, and a pachinko ball that is pumped to the inclined lower surface side opposite to the introduction port 12 is provided at the upper position. Is provided in the supply ramp 7, and the opening area of the outlet 13 is the inlet 12.
Is larger than the opening area.

Although the shapes of the inlet 12 and the outlet 13 are square in this embodiment as described above, the present invention is not limited to this, and these shapes may be changed to other shapes. A polygonal shape may be used. In this case, a space is appropriately provided between the pachinko balls flowing in and out, and the occurrence of clogging can be prevented.

Further, as in the present embodiment, by increasing the opening area of the discharge port 13 to be larger than the opening area of the introduction port 12, the amount of the pachinko balls discharged is reduced.
It is preferable because it is possible to prevent the pachinko balls from being clogged at the discharge port 13 beyond the amount of pachinko balls that can pass through.

Inside the cylindrical case 11, there is provided a screw rotor 14 provided with a continuous spiral ridge 15 whose outer diameter is slightly smaller than the inner diameter of the cylindrical case.

The ramp 5 is fixed to the inlet 12 by a holder 19.

The operation of the pachinko ball relay lift 6 according to the present embodiment will now be described with reference to FIG. 3. The pachinko ball 20 discharged from the stock tank 4 and moving on the ramp 5 is inclined. Inlet 1 provided on the upper surface
2, the fluid flows into the cylindrical case 11 by its own weight.

The pachinko balls 20 that have flowed in are sequentially moved above the cylindrical case 11 by the rotation of the screw rotor 14 in a predetermined direction, reach the discharge port 13 and are discharged.

If the pitch interval of the spiral ridges 15 provided on the screw rotor 14 is too large, the inclination of the spiral ridges 15 becomes large, and the pachinko balls fall downward inside the cylindrical case 11. If the rate of dropping to the side increases and the carrying capacity is reduced, and if this is too small, the space volume in which the pachinko balls can exist inside the cylindrical case 11 decreases, and the carrying amount decreases, Preferably, the diameter is about 2.5 to 5 times the diameter of the pachinko ball 20, but the present invention is not limited to this.

The vertical width A of the cylindrical case 11 at the inlet 12 is at least 2.5 times the diameter of the pachinko balls 20 so that at least two pachinko balls 20 can overlap and pass. In addition, it is preferable that the pitch is not more than 0.9 times the pitch interval between the spiral ridges 15, but the present invention is not limited to this.

By doing so, the pachinko ball 2
0 can smoothly flow into the cylindrical case 11 and the pachinko ball 20 can be prevented from being bitten at the inlet 12.

If the angle of inclination of the cylindrical case 11 with respect to the horizontal plane is too large, the amount of slingshot balls falling inside the cylindrical case will increase, and the lifting capacity will decrease. Since the length of the cylindrical case 11 required for lifting to a predetermined height position becomes long, the inclination is preferably set in a range of 20 to 65 degrees.

Further, the sling path 5 and the pachinko ball 20 flow into the inlet 12 at an angle perpendicular to the axis of inclination of the cylindrical case as in this embodiment. Preferably, by doing so, the amount of pachinko balls flowing into the cylindrical case 1 can be increased.

Although the embodiments of the present invention have been described in the above embodiments with reference to the drawings, the present invention is not limited to these embodiments, and changes and additions may be made without departing from the gist of the present invention. It goes without saying that even if there is, it is included in the present invention.
