【Example】
An embodiment of the present invention will be described below with reference to the drawings. First, the configuration of the pachinko island platform 1 to which the introduction rod 30 according to the embodiment is applied will be described with reference to FIG. FIG. 4 is a partially broken front view showing the internal structure of the pachinko island platform 1. In the figure, the pachinko island stand 1 is a line-up of a large number of pachinko machines 2 as is well known, and a ball feeder 3 is erected in the center. In the ball lifting machine 3 in this embodiment, an endless conveying belt 5 is rotationally driven by a lower pulley 4 incorporating a motor, and an introduction rod 30 and an inflow rod 6 (described later) are caused by the frictional force of the conveying belt 5 (FIG. 2). The ball guided through the upper surface of the polishing cloth is lifted while contacting a polishing cloth (not shown) mounted on the polishing cloth mounting door 16 (see FIG. 2), and finally discharged from the discharge port 7 at the upper end. .
[0007]
The polished balls discharged from the discharge port 7 are temporarily stored in the upper storage tank 8, and then flow out from the replenishment rod 10 connected to the bottom surface of the upper storage tank 8. The replenishment trough 10 is provided so as to be inclined from the upper storage tank 8 toward both ends of the pachinko machine platform 1, and is connected to each pachinko machine 2 by a shunt 11 provided corresponding to each pachinko machine 2 in the middle thereof. It is supplied to a well-known prize ball tank provided at the upper back. As is well known, the flow divider 11 is provided with a counting device for counting the number of balls replenished, and a replenishing ball signal is sent from this counting device to a management computer provided in the game hall. It has become.
[0008]
A reflux pipe 9 is connected to the upper part of the upper storage tank 8 slightly above the middle. This reflux pipe 9 uses less prize balls in the pachinko machine 2 and does not require replenishment of balls to the replenishment basket 10, and as a result, when the number of balls stored in the upper storage tank 8 increases, surplus The balls are returned to the lower storage tanks 15 installed on both lower sides of the ball feeder 3.
[0009]
On the other hand, from each pachinko machine 2, the balls that have been driven are discharged to a used ball tank 12 provided at the lower back of the pachinko machine 2, and are returned to the recovery basket 14 by a discharge pipe 13 that extends downward from the tank 12. Discharged. The collection baskets 14 are provided in an inclined shape from both ends of the pachinko island platform 1 toward the lower part of the ball lifting machine 3 standing at the center of the pachinko island platform 1. The used ball tank 12 is provided with a counting device for counting the number of balls collected as is well known, and a collected ball signal is sent from this counting device to a management computer provided in the game hall. It is like that.
[0010]
By the way, the recovery basket 14 reaches the lower part of the ball hoisting machine 3 so as to penetrate the inside of the lower storage tank 15 arranged on both sides of the ball hoisting machine 3. In the lower storage tank 15, the balls stored in the lower storage tank 15 do not flow out to the recovery basket 14 and flow down the recovery basket 14 while there are balls flowing down the recovery basket 14. When the number of balls has become insufficient, the balls stored in the lower storage tank 15 flow out to the collection basket 14 to supply the balls. Note that the number of balls stored in the two lower storage tanks 15 is based on the pachinko island stand 1 configured to return the prize balls acquired by the player to the prize ball return device attached to the pachinko island stand 1. A prize designed to store enough balls (eg, about 100,000 balls) required in various gaming conditions, while prize balls won by players are provided at a corner of the game hall The pachinko island 1 that is configured so as to be returned to the prize ball return device installed at the exchange and not directly returned to the pachinko island 1 will have a sufficient amount of balls (for example, enough to cope with a sudden shortage of prize balls) About 20,000).
[0011]
In the pachinko island platform 1 configured as described above, the balls polished and lifted by the ball lifter 3 are supplied to each pachinko machine 2 via the replenishment basket 10, while being used in each pachinko machine 2. The used balls are collected in the ball lifting machine 3 by the collecting rod 14, polished and fed again, and supplied to the replenishing rod 10. That is, the balls are circulated within the pachinko island platform 1. Thus, in order to connect the left and right recovery rods 14 inclined from the end of the pachinko island base 1 toward the center and the inflow rod 6 of the ball lifter 3, they are orthogonal to the recovery rod 14. It is necessary to provide the introduction rod 30 in the direction and on the extension of the inflow rod 6. Accordingly, the relationship between the collection basket 14 and the introduction basket 30 will be described below with reference to FIGS. 1 to 3. FIG. 1 is a plan view showing the relationship between the collection basket 14 and the introduction basket 30, FIG. 2 is a side view showing the relationship between the collection basket 14 and the introduction basket 30, and FIG. It is sectional drawing cut | disconnected by the -A line | wire.
[0012]
In the figure, the recovery rod 14 and the introduction rod 30 are arranged in a stepped manner so that the recovery rod 14 is in the upper direction in the orthogonal direction, and balls fall on the collection rod 14 at the overlapping portion. A falling opening 20 is formed. The drop opening 20 is formed with an arcuate opening edge 21 so as to open toward the ball lifting machine 3. For this reason, the balls that have flowed down with the collection baskets 14 aligned fall smoothly and smoothly from the center to the end of the introduction basket 30. In other words, the balls can be moved smoothly without reducing the ability to supply the balls from the collection basket 14 to the introduction basket 30.
[0013]
On the other hand, a plurality of partition walls 31 are erected on the introduction rod 30 at intervals slightly larger than the diameter of the balls, parallel to the direction of the ball feeder 3, and the balls flowing down the introduction rod 30 by the partition walls 31. Are arranged in a row, and the ball guiding path 32 is connected to the inflow rod 6 to feed the balls in order. And since the upstream part of the partition wall 31 is formed so that it may become short gradually from the center part to the edge part of the introduction rod 30, the ball which falls from the fall port 20 combined with the shape of the arc-shaped opening edge 21 Can be evenly guided to the ball guide path 32 formed by the respective partition walls 31.
[0014]
Thus, in the relationship between the recovery rod 14 and the introduction rod 30 configured as described above, the balls flowing down the recovery rod 14 fall from the drop port 20 to the introduction rod 30, but the opening edge 21 of the drop port 20. Is formed in an arc shape so as to open toward the ball lifting machine 3, so that it falls evenly from the center part to the end part of the introduction rod 30, and the dropped ball is the center of the introduction rod 30. It is quickly supplied to the doffing machine 3 by the partition wall 31 erected so that the upstream part gradually shortens from the part to the end part. That is, in this embodiment, since the introduction rod 30 can be formed in a straight line, not only the manufacture of the introduction rod 30 is easy, but also the installation area can be reduced because the introduction rod 30 is not curved. The interior of the pachinko island stand 1 can be used effectively.
[0015]
Further, in the present embodiment, since the collection basket 14 and the introduction basket 30 are formed in a step shape without being directly connected, the inclination angle of the collection basket 14 is effectively set within a predetermined range. be able to. Further, the installation direction of the conveyor belt 5 of the ball hoisting machine 3 is parallel to the recovery rod 14, that is, the abrasive cloth mounting door 16 shown in FIG. 2 is positioned on the side facing the longitudinal direction of the pachinko island platform 1. Therefore, if the maintenance door (not shown) provided at the position of the pachinko island platform 1 corresponding to the ball feeding device 3 is opened, the polishing cloth decoration door 16 can be opened immediately, so that the polishing cloth can be replaced. Can be easily performed.
[0016]
In the above-described embodiment, the shape of the opening edge 21 of the drop port 20 is an arc shape, but may be a linearly inclined shape, for example.
[0017]
