Description

The present invention relates to a pachinko ball hoisting device which is provided in a pachinko ball stand in a game arcade and hoists a pachinko ball to an upper tank.

As is well known, the pachinko island stand of the pachinko game arcade where a large number of pachinko machines are installed side by side has a storage tank inside, and the pachinko balls discharged from each pachinko machine are collected in the storage tank through a ball collection gutter. The pachinko balls accumulated in the storage tank are lifted to an upper tank by a pachinko ball lifting device provided in the island stand, and the pachinko balls are supplied from the upper tank to each pachinko machine through a ball supply gutter. I am trying to do it.

The pachinko ball lifting device shown in Patent Document 1 joins the pachinko balls and the abrasive pellets and pumps them by the pumping device to attach dirt on the pachinko balls to the polishing pellets and then pumps them. At the same time, the pachinko balls are polished.
Further, the pachinko ball lifting device shown in Patent Document 2 has a configuration in which the lower part of the lifting tube is curved in an arc shape so that the pachinko ball flows in from a lower end opening of the lifting tube.

By the way, the upper tank is of a size capable of always storing a large number of pachinko balls (usually 30,000 on one island stand) so that the pachinko balls can be continuously supplied to a large number of pachinko machines. Therefore, the total weight of the pachinko balls stored in the upper tank is several tens of kilograms, but conventionally, the upper tank is supported by the beams and columns that form the island stand. For this reason, it becomes necessary to make the beams and columns of the island stand robust enough to withstand this weight, and to reinforce the part that supports the upper tank, increasing the cost of building the island stand and increasing the construction period. There was a problem that it became longer.
The present invention is intended to solve these problems.

To this end, the pachinko ball lifting device according to the present invention is a vertically supported pachinko ball lifting cylinder, in which a shelf member is fixed to the upper outer periphery of the lifting cylinder so as to project substantially evenly around the lifting cylinder, and the upper tank Is supported on the shelf member, and the pachinko balls pumped by the lifting cylinder are evenly distributed and stored in the upper tank and around the lifting cylinder. It is a feature.
Therefore, the upper tank is always supported by the lifting cylinder, and an excessive weight load is not applied to the island stand.
Further, in the pachinko ball lifting device according to the present invention, an outlet is formed at the center of the bottom of the upper tank, and an overflow pipe connected to the outlet is passed through a through hole formed in the shelf member. When the pachinko balls are fully stored in the tank, the pachinko balls are guided to a storage tank provided below.
By thus passing the overflow pipe through the shelf member, the load of the pachinko ball is always supported by the lifting cylinder without deviation.

According to the present invention, since the load of the upper tank is received by the lifting cylinder, an excessive weight load is not applied to the island stand. Therefore, it is not necessary to reinforce the island stand for the upper tank as in the conventional case, and the construction cost of the island stand can be reduced and the required construction period can be shortened.

An outlet 57 is provided between the floor plates 38a and 38b in the overflow chamber 39, and the upper end of the overflow pipe 22 is connected to the outlet 57.

In the pachinko ball lifting apparatus configured as described above, the pachinko balls t in the storage tanks 2a and 2b are guided to the inflow casings 15a and 15b through the inclined troughs 3a and 3b and flow into the lateral transfer cylinder 9, and the pellet tank 20 The abrasive pellets p are supplied into the lateral transfer tube 9 from the above, whereby the abrasive pellets p and the pachinko balls t are mixed in the lateral transfer tube 9. The pachinko ball t is conveyed along with the polishing pellets p in the direction of the delivery cylinder 4 by rotating the spiral rotation body 14 in a predetermined direction, and the spiral rotation body 8 in the delivery cylinder 4 moves in a predetermined direction. The pachinko balls t are pumped together with the polishing pellets p by being driven to rotate, and the pachinko balls t are polished by the pachinko balls t coming into contact with the polishing pellets p during the pumping. Then, the abrasive pellets p discharged from the upper end opening 4a of the lifting cylinder 4 fall into the vertical cylinder 40 from the slats 47a to 47e and are returned to the pellet tank 20 via the pellet return pipe 21. On the other hand, the pachinko ball t discharged from the upper end opening 4a of the lifting tube 4 slides on the slats 47a to 47e as shown by the arrow in FIG. 11, reaches the ball dropping part 49, and flows into the storage chamber 37. Thus, the ball dropping part 49 is located in the center of the storage chamber 37, and the partition plates 36a and 36b, which are the floors of the storage chamber 37, are stretched in a mountain shape. The t is divided substantially evenly into the left and right, and is uniformly stored in the storage chamber 37 without losing the left and right balance. Therefore, the pachinko balls that have been pumped are evenly distributed and stored around the pumping cylinder 4, and the pachinko balls that are stored in the storage chamber 37 are discharged from the outlets 52a and 52b and the slant gutter 6a. , 6b to be sent to a large number of pachinko machines. In addition, when a large number of pachinko balls are stored in the storage chamber 37 above the height of the overflow outlet 51, the pachinko balls fall through the overflow cylinder 50 into the overflow chamber 39 and overflow from the outlet 57. It flows down to the storage tank 2a through a pipe 22, a turning box 23, and an inclined gutter 23a.

Since the outlet 57 is formed at the center of the bottom of the upper tank 5 and the overflow pipe 22 connected to the outlet 57 is passed through the through hole 34 formed in the shelf member 30, Even if the pachinko balls are concentrated on the overflow pipe 22, the load of the pachinko balls does not deviate and the balance is maintained by being supported by the lifting tube 4 at all times.

As described above, in the pachinko ball lifting device according to the present invention, the pachinko balls pumped by the lifting cylinder 4 are evenly stored in the upper tank 5 around the lifting cylinder 4, and the load of the pachinko balls is increased. Is always hung on the lifting tube 4. For this reason, even if a large number of pachinko balls are stored in the upper tank 5, the heavy load thereof will not be applied to the pachinko island stand. Therefore, it is not necessary to reinforce the pachinko island stand to have a robust structure as in the conventional case, the construction cost of the pachinko island stand can be reduced, and the required construction period can be shortened. Further, since the pachinko ball lifting device according to the present invention is installed without imposing a weight burden on the pachinko island stand, the device can be installed or replaced regardless of the structure of the island stand, and maintenance is possible. There is a remarkable effect that it becomes easier.
