DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an island exchange type ball comprising a main pachinko island having a base tank for storing a large amount of pachinko balls, and a slave pachinko island receiving a pachinko ball supplied from the base tank. The present invention relates to a transfer device.

[0002]

2. Description of the Related Art Conventionally, a plurality of pachinko islands are formed as one block and a supply gutter (also referred to as an AC gutter) is provided between upper tanks.
From a pachinko island that has a large storage tank (hereinafter referred to as a base tank) to a pachinko island that does not have a base tank (hereinafter a slave pachinko island). (2) A ball transfer device of an island exchange type is known in which a pachinko ball is always supplied to the main pachinko island and a pachinko ball overflowing on a secondary pachinko island is returned to a base tank of the main pachinko island. In this island exchange type ball transfer device, since the amount of balls stored in the slave pachinko island stand is always satisfied, there is no shortage of balls in the slave pachinko island stand, and the equipment cost is low. As such, it is used in many playgrounds. Further, in the island exchange type ball transfer device, as disclosed in Japanese Patent Application Laid-Open No. 9-38311 proposed earlier by the present applicant, the pachinko balls overflowing on the slave pachinko island stand are returned to the main pachinko through a return gutter. The water flows into the main upper tank of the island, and is returned to the base tank from a return hose having an upper end connected to the main upper tank and a lower end connected to the base tank. Balls overflowing from the upper tank of the main pachinko island stand are returned to the base tank from an overflow hose whose upper end is connected to the main upper tank and whose lower end is connected to the base tank. In this manner, the base tank stores overflow balls of the secondary pachinko island that are returned from the return hose and overflow balls of the main pachinko island that are returned from the overflow hose.

[0003]

However, the amount of the pachinko balls discharged from the return hose for returning the overflowing balls of the secondary pachinko island stand to the base tank from the overflow hose for returning the overflowing balls of the main pachinko island stand and the like. Since the timing is irregular, that is, it cannot be predicted, the accumulation of pachinko balls in the extremely large base tank is not constant, and the accurate ball of the ball quantity sensor for grasping the ball quantity in the base tank is not accurate. There is a problem that it is difficult to determine the mounting position for measuring the amount. The present invention
In view of the above circumstances, it is an object of the present invention to provide an island exchange type ball transfer device in which it is easy to determine a mounting position where a ball amount sensor can accurately measure a ball amount.

[0004]

Means for Solving the Problems In order to achieve the above-mentioned object, the invention according to claim 1 comprises a main pachinko island stand having a base tank for storing a large amount of pachinko balls; In an island-type ball transfer device comprising a slave pachinko island that receives a supply, the main pachinko island includes a main upper tank that stores pachinko balls discharged by a ball discharging device in the island, and a main upper tank that stores the pachinko balls. A supply gutter for supplying pachinko balls stored in the upper tank to a pachinko machine installed in the island, a supply gutter for supplying pachinko balls stored in the main upper tank to the slave pachinko island, A main overflow mechanism for returning the pachinko balls overflowing to the tank to the base tank, wherein the secondary pachinko island stores the pachinko balls discharged by the ball discharging device in its own island, and An upper tank for receiving pachinko balls supplied via a gutter, a replenishing gutter for replenishing pachinko balls stored in the upper tank to a pachinko machine installed on the island, and an overflow of the upper tank. A return mechanism for returning the pachinko balls to the base tank, wherein the base tank is formed by partitioning the inside thereof into a plurality of tank units in which the storage order in which the pachinko balls are stored is determined, and A pachinko ball returned from the main overflow mechanism and the return mechanism to the base tank is provided with a dispersing mechanism for dispersing the pachinko balls so as to be stored in each tank section partitioned according to the storage order. With this configuration, even if it is not possible to predict the amount and timing of the pachinko balls overflowing from the secondary pachinko island and the primary pachinko island, the pachinko that overflows from the secondary pachinko island and the primary pachinko island. Since the balls are sequentially stored by the dispersing mechanism in accordance with the storage order in each of the tank portions in which the base tank is divided into a plurality of pieces and the volume is reduced,
By appropriately attaching a ball quantity sensor to each of the partitioned tank portions, an accurate ball quantity in the base tank can be measured. That is, it becomes easy to determine the mounting position where the accurate ball amount of the ball amount sensor can be measured.

Further, in the invention according to claim 2, the plurality of tank portions are provided with respective lead-out passages for leading pachinko balls stored in the respective tank portions, and the pachinko balls led out from the lead-out passages are provided. By providing a merging section for sending to the ball-lifting device provided on the main pachinko island stand after merging, since the pachinko balls stored in each tank section can always be derived, all tanks The dead ball can be prevented by the section, and the pachinko ball can be smoothly fed to the ball fryer.

In the invention according to claim 3, in the merging portion, the ratio of the amount of pachinko balls sent from the merging portion to the ball-lifting device is made larger than the amount of pachinko balls from the tank portion having a higher storage order. By adopting a priority guiding structure so that the amount of pachinko balls from the tank unit with a lower storage order is larger, the tank with a lower storage order than the amount of balls derived from the lead-out passage of the tank unit with a higher storage order The reversal phenomenon occurs that the higher the storage order, the tank portion with the lower storage order becomes empty more quickly than the lower storage portion, because the larger the amount of the ball drawn out from the discharge passage of the portion is derived. The number of remaining balls can be accurately measured without any problem.

Further, in the invention according to claim 4, the dispersing mechanism comprises a main overflow dispersing mechanism for dispersing pachinko balls sent from the main overflow mechanism to a plurality of tanks in accordance with the storage order. A return dispersing mechanism configured independently of the main overflow dispersing mechanism and dispersing the pachinko balls sent from the return mechanism to a plurality of tank units in accordance with the storage order; Even if overflowing balls are sent from each of the mechanism and the return mechanism, the overflowing balls can be smoothly sent to each tank without interference between the overflowing balls.

Further, the two pachinko island stands 1c and 1d which are positioned so as to be sandwiched between the main pachinko island stands 1a, 1b, 1e and 1f (the symbols are omitted in the left and right blocks because they are not shown in FIG. 1). The sub-pachinko islands 1c, 1d are located between the two main pachinko islands 1b, 1c and receive the supply of pachinko balls from the base tanks B1, B2. Such a form in which four pachinko islands are connected as one block by a ball transfer device to be described later to transport the pachinko balls is called island exchange. In the illustrated embodiment, four pachinko islands are described as constituting island exchange, but not necessarily four, but two.
What is necessary is just what is comprised by the above-mentioned pachinko island stand. For example, one main pachinko island and one or more slave pachinko islands may be connected by a ball transfer device, or one or more slave pachinko islands may be arranged between two main pachinko islands to accommodate balls. It may be connected by a transfer device.

In each of the base tanks B1 and B2 in such island exchange, the amount of pachinko balls required in each block can be stored.
Assuming that the number of balls required for one pachinko island is 500,000, four pachinko islands 1b constituting one block are formed.
The number of pachinko balls required for 1e is 2 million. Then, the base tank B1 has about one million pachinko balls out of the two million pachinko balls required for the central blocks 1b to 1e and the pachinko balls 20 required for the left block to 1a.
It has a capacity to store a total of about 2 million pachinko balls including about 1 million pachinko balls out of 100,000,
The base tank B2 has about 1 million remaining pachinko balls required for the central blocks 1b to 1e and the right block 1f to 1m.

And return gutters 11 and 12 and return passages 19 and 20 for returning excess pachinko balls to the base tanks B1 and B2 on the secondary pachinko islands 1c and 1d, and excess on the main pachinko islands 1b and 1e. And overflow ball paths 31 and 32 for returning pachinko balls to the base tanks B1 and B2.

In the above-mentioned ball transfer device, the supply gutters 6, 7
Are upper tanks 2b, 2e of main pachinko islands 1b, 1e located on both sides (hereinafter, main pachinko islands 1b, 1e).
The upper tanks provided in the main upper tanks 2b and 2e are intersected. This supply gutter 6,
Reference numeral 7 penetrates the inside of upper tanks 2c and 2d of the secondary pachinko islands 1c and 1d (hereinafter, upper tanks provided on the secondary pachinko islands 1c and 1d are referred to as secondary upper tanks 2c and 2d). At the same time, supply gutter 6,7 inside
The pachinko balls supplied from the tanks fall from the not-shown drop openings into the respective upper upper tanks 2c and 2d. For this reason, when there is room for receiving pachinko balls in the upper tanks 2c and 2d of the secondary pachinko islands 1c and 1d (when the storage amount of the secondary pachinko islands 1c and 1d is small), the pachinko balls are placed on the secondary pachinko island 1c. , 1d. The connection between the supply gutters 6 and 7 and the main upper tanks 2b to 2e is performed through joints provided in the respective upper tanks, and the supply gutters 6 and 7 formed in advance in the respective upper tanks. Are connected so as to correspond to the upstream inlet and the downstream outlet, so that they are penetrated as a whole. The downstream end of the supply gutter 6 is connected to the supply passage 24 extending from the main upper tank 1e to the return ball branch box 17 of the base tank B2. The downstream end of the supply gutter 7 is connected to the return of the base tank B1 from the main upper tank 1b. Each of them is in communication with a supply passage 23 connected to the ball branch box 16.

In addition, the position immediately after the upper tank 2d of the supply gutter 6 and the position immediately after the lower tank 2c of the supply gutter 7 are:
Shutter devices 15 and 14 each including a shielding plate (not shown) and a motor for opening and closing the shielding plate are provided. The shutter devices 15 and 14 constitute a part of the ball transfer device and include base tanks B1 and B1.
2 is electrically controlled by a control board (not shown) in accordance with the amount of balls stored in the base 2. In the open state, the pachinko balls flow down the supply gutters 6 and 7 and the base having a large storage amount The pachinko balls are transferred from the tank to the base tank having a small storage amount, and in a closed state, the pachinko balls are stagnated upstream of the shutter devices 15 and 14 in the supply gutters 6 and 7. And, as described above, the slave pachinko island stand 1
The pachinko balls are always supplied to the upper tanks 2c and 2d c and 1d, and the storage amounts of the sub-pachinko islands 1c and 1d are always filled. In FIG. 1, the shutters 15 and 14 are installed at positions immediately after the upper tanks 2d and 2c of the slave pachinko islands 1d and 1c, but the main pachinko islands 1e and 1b are shown.
May be provided immediately before the main upper tanks 2e and 2b.

In the above-described ball transfer device, return gutters 11, 12 and return passages 19, 20 for returning excess pachinko balls to the base tanks B1, B2 in the pachinko islands 1c, 1d are returned. Gutters 11 and 12 are sub tanks 2
The return gutters 11 and 12 are connected to the main upper tanks 2b and 2e so as to be inclined downward from the c and 2d, and communicate with the return passages 19 and 20 through the main upper tanks 2b and 2e. . The return passages 19 and 20 connect the main upper tanks 2b and 2e with the return ball branch boxes 16 and 17.

Further, of the above-mentioned ball transfer devices, overflow ball passages 31, 32 for returning excess pachinko balls in the main pachinko islands 1b, 1e to the base tanks B1, B2.

8 is connected so as to be inclined downward.

The reason why the return gutters 11 and 12 and the return passages 19 and 20 are provided is mainly that the ball counting and returning devices 43 and 44 are provided on the slave pachinko islands 1c and 1d at their island ends (not necessarily at the island ends). For example, at the center of the island). Therefore, the ball counting and returning device 4
When the number of pachinko balls returned by the third and fourth pachinko machines becomes extremely large, the pachinko balls cannot be stored in the upper tanks 2c and 2d and the lower tanks 3c and 3d built in the sub-pachinko island stands 1c and 1d. The pachinko balls discharged by the device 52 are returned from the lower tanks 1c and 1d to the return gutter 11,
12 and the base tank B via the return passages 19 and 20
This is because it is necessary to return it to B1 and B2. The reason for providing the overflow ball passages 31 and 32 is as follows.
Not only because the ball counting and returning devices 42 and 45 are provided in b and 1e, but also the ball lifting device 52 provided in the main pachinko island stand 1b and 1e is constantly driven to lift the pachinko balls. This is because when the pachinko balls that have been pumped out become excessive in the main upper tanks 2b and 2e, the pachinko balls overflowing are circulated between the base tanks B1 and B2.

In FIG. 1, the main upper tank 2a of the main pachinko island stand 1a belonging to the left block and the main upper tank of the main pachinko island stand at the left end (not shown) of the same block are crossed. Supply gutters 4 and 5 and main upper tank 2a

And a ball transfer device consisting of

As described above, a plurality of pachinko islands 1 in the form of island exchange.
The outline of a to 1f has been described. Next, the internal structure of each pachinko island stand will be described, and then the respective components constituting the main part of this embodiment will be described. First, the internal structure of the pachinko island stand will be described with reference to FIG. 2. FIG. 2 shows the internal structure of the slave pachinko island stand 1c, and the slave pachinko island stand 1d has substantially the same structure. Regarding the main pachinko islands 1a, 1b, 1e, 1f (hereinafter referred to as the main pachinko islands 1b, etc.), the structure of the upper tank and the lower tank, and the structure of the overflow and the structure of the sub-pachinko islands are related. 1c, but all other structures are the same.

In FIG. 2, in the sub-pachinko island stand 1c, a sub-tank 3c (about 20,000) for storing a relatively small number of pachinko balls is built in, and the pachinko balls stored in the sub-tank 3c. Is transported to the upper tank 2c by a ball lifting device 52 installed substantially at the center of the slave pachinko island stand 1c in the longitudinal direction, and the pachinko machine 50 and the ball lending machine installed on each slave pachinko island stand 1c. Balls are supplied to the 51 via a supply gutter 53. Pachinko machine 50
The pachinko balls used in (1) are collected by the out-ball collecting gutter 54 via the out-ball box 55, guided to the lower tank 3c, and then pumped again by the ball-lifting device 52. As a result, the pachinko balls circulate in the slave pachinko island 1c.

The lower tank 3c built in the sub-pachinko island stand 1c is formed in a rectangular parallelepiped shape, and has a bottom plate on the bottom surface which is inclined downward toward the introduction gutter 57 of the doffing and feeding device 52. Further, since the lower tank 3c is installed on one side of the doffing and conveying device 52 (the right side of the doffing and conveying device 52 in FIG. 2), the opposite side (in FIG.
In order to guide the pachinko balls flowing through the out ball collecting gutter 54 installed on the left side of the outer ball collecting trough 54 to the lower tank 3c, a connecting gutter 56 is inserted between the out ball collecting gutter 54 and the lower tank 3c to collect pachinko balls. are doing. The end of the connecting gutter 56 is slightly above the connection position of the introduction gutter 57. The lower tank 2c is connected to the lower tank 3c via an overflow passage (not shown) formed along the side surface of the doffing and feeding device 52 for pachinko balls overflowing with the supply gutter 53.
When the pachinko balls overflow even in the overflow passage, the pachinko balls are sent to the return gutter 11. Further, the subordinate upper tank 2c has a structure in which pachinko balls supplied from the supply gutters 6 and 7 flow down to the subordinate lower tank 3c via a suction passage (not shown) formed adjacent to the overflow passage. ing. The overflow passage constitutes a slave overflow mechanism and is not provided in the main pachinko island stand 1b or the like. Also, a suction passage is not provided in the main pachinko island stand 1b or the like.

In the case of the illustrated embodiment, the ball lifting device 52 is provided with a lifting belt swivel-driven by a motor built-in pulley, and a pachinko machine provided facing the lifting belt and between the lifting belt. And a polishing cloth for polishing while holding the balls, wherein the pachinko balls guided from the introduction gutter 57 are lifted while being ground upward by the frictional force of the lifting belt.

The sub-pachinko island stand 1c has been described above. Here, the sub-pachinko island stand 1c and the main pachinko island stand 1b
Differences from the above will be described. First, in the lower tank, the slave pachinko island stand 1c receives pachinko balls from the collection gutter 54, the overflow passage and the suction passage, whereas in the main pachinko island stand 1b and the like, the collection gutter 54 and the base tanks B1 and B2 receive the pachinko balls. Accept pachinko balls.
Next, while the secondary pachinko island 1c has an overflow passage and a suction passage, the primary pachinko island 1
b, etc. are not provided. Next, the secondary pachinko island 1c sends the pachinko balls in the upper tank in the order of the supply gutter 53, the overflow passage, and the return gutter 11, while the main pachinko island 1b and the like supply the pachinko balls in the upper tank. The pachinko balls are sent in the order of the gutter 53 and the overflow ball passage 31. This is because the secondary pachinko island stand 1c has only the secondary lower tank 3c to secure a certain amount of balls and suppress unnecessary supply from the supply gutter 6, whereas the primary pachinko island The table 1b and the like are provided with the main pachinko island 1 because the balls are sent from the base tanks B1 and B2.
This is because there is no need to secure a ball in b or the like.

Next, the structure of the main upper tanks 2a, 2b, 2e, 2f (hereinafter referred to as the main upper tank 2b, etc.) such as the main pachinko island stand 1b will be described with reference to FIGS. Here, as the upper tank of the main pachinko island stand, the main upper tank 2b of the main pachinko island stand 1b will be described as an example.

The pachinko balls discharged by the discharging device 52 are discharged to the main upper tank 2b. The main upper tank 2b supplies the received pachinko balls with the supply gutter 53 and the supply gutter 6.
Alternatively, it has a function of distributing to the overflow ball passage 31.
As shown in FIG. 3, the main upper tank 2 b has a gutter installation space 60 through which a partition plate fixed in the vertical direction penetrates the downstream of the supply gutter 7 and the downstream of the return gutter 11.
A gutter installation space 61 where the upstream part of the supply gutter 6 is installed, a diversion space 62 where the pachinko balls pumped by the ball lifting device 52 are sorted and sorted, and an upper portion of the ball lifting device 52 is provided through. And a space 63 for setting up a lifting device. The ball outlet of the ball lifting device 52 installed in the lifting device installation space 63 faces the branch flow space 62.

The pachinko balls discharged from the ball outlet of the doffing and feeding device 52 fall onto a drop receiving plate 64 fixed in a horizontally inclined manner above the branch space 62, and the drop receiving plate 6
4 is blocked by a blocking plate 65 erected and fixed, and falls downward from a first priority drop port 66 formed on the upstream side of the blocking plate 65. The pachinko ball that has fallen from the first priority drop port 66 is shown in FIG.
As shown in the figure, step plates 67a, 67 provided in a step shape are provided.
b, the main upper tank 2b is formed by the first replenishment guide plates 68a to 68c formed in steps while being weakened by b.
To the first supply gutter connection port 69 which is opened on one of the left and right side surfaces. The first supply gutter connection port 69 is connected to the supply gutter 53 provided to be inclined toward the right island end of the pachinko island stand in FIG. When the right supply gutter 53 is full of pachinko balls and pachinko balls are also clogged on the first supply guide plates 68a to 68c, the first supply guide plate 68a on the most upstream side is slightly upstream. And the second supply guide plates 70a and 70b which are formed in the shape of inclined steps which are opposite to the first supply guide plates 68a to 68c.
The pachinko ball flows out and is guided to the second supply gutter connection port 71. The second supply gutter connection port 71 is connected to a supply gutter 53 provided to be inclined toward the left end of the pachinko island in FIG.

As described above, the pachinko balls that have been ground and fed by the doffing and feeding device 52 are first sorted so as to be preferentially supplied to the supply gutter 53 of the island. The main upper tank 2b has a structure in which one supply gutter 53 is full and then the other supply gutter 53 is replenished as described above. Since the amount of pumping per unit time is much larger than the average amount of balls consumed through one supply gutter 53, both supply gutters 53 are always supplied with pachinko balls.

Next, when the supply of pachinko balls to both supply gutters 53 is sufficiently spread, the balls are jammed in the step plates 67a and 67b, and the pachinko balls do not drop from the first priority drop port 66. Then, as shown in FIG.
The pachinko balls polished and pumped by 2 pass over the baffle plate 65 and are supplied to the supply gutter 6 from the supply gutter outlet 72 formed in a partition plate that partitions the gutter installation space 61 and the branch flow space 62.
Outflow to Since the supply gutter 6 is provided with the shutter device 15 immediately after the upper upper tank 2d as described above, when the shutter device 15 is released, the supply gutter 6 is connected to the slave pachinko island stands 1c and 1d and the base tank B2. The pachinko balls are supplied, and conversely, when the shutter device 15 is closed, the pachinko balls are supplied only to the slave pachinko islands 1c and 1d.

Then, as described above, the shutter device 15
Is closed and the pachinko balls are full of the slave pachinko islands 1c and 1d, the supply gutter 6 is full of pachinko balls. Therefore, as shown in FIG. 5, the pachinko balls released to the drop receiving plate 64 are overflowed from below the ball outlet of the doffing and feeding device 52 into the overflow vertical gutter 73 (step plate 6).
7a, 67b) and overflow guide plates 74a, 74b formed in steps.
Through the overflow port 75. The overflow port 75 is connected to the base tank B
1 is connected to the overflow ball passage 31 (see FIG. 1) for returning the ball to 1. In addition, the passage leading to the overflow port 75 and the overflow ball passage 3 in the main upper tank 2b.
