2. Description of the Related Art In a pachinko hall, a group of ball game machines in which a plurality of ball game machines are lined up and arranged in two rows with their backs facing each other is called an island. Pachinko halls are constructed by installing multiple units with this island as one unit.
Balls (also called balls and pachinko balls) used in ball game machines are usually used by customers to exchange balls for coins or bills at ball lending machines installed between ball game machines. Put in

Play with a ball game machine using this ball,
Customers can get balls, which are usually called prize balls. The number of prize balls released from the ball game machine is greater than the number of out balls that are exchanged and hit at the ball lending machine,
The number of balls circulating on the island mentioned above gradually decreases during business hours. This reduction rate varies depending on the operating rate of each gaming machine, the ball output rate, etc., so the number of ball stocks and the number of circulations are different and unevenly distributed depending on the island. If this uneven distribution is left, the prize balls may not be released depending on the place.

Therefore, it is necessary to average the number of balls on each island, and many methods for averaging the number of balls have been proposed. For example, in the pachinko ball possession level averaging device proposed in Japanese Patent Publication No. 62-24110, a prize ball counter is installed on each island, and the customer puts the prize ball into the prize ball counter. Count and return the prize ball after this count to the island,
When the amount of pachinko balls held reaches a certain level or more, the use of the prize ball counter is stopped and averaged.

In the same manner, Japanese Patent Laid-Open No. 6-32687 discloses a gate for enabling or stopping the use of the exchange ball counter (prize ball counter) by increasing or decreasing the amount of balls in the exchange ball pool tank. If the amount of balls in the out-ball tank decreases, the supply balls in the replenishing ball pool tank are guided to the polishing lift when the amount of balls in the out-ball tank decreases, and if the amount of balls in the replenishing ball pool tank decreases, the exchange balls in the exchange tank pool replenishing pool When the amount of balls introduced into the tank and the amount of balls in the exchange ball pool tank decreases, the gate member is activated to enable the exchange ball counter.

Lifting Ball Processing Tank 40 FIG. 7 is a detailed view of the upper portion of the storage tank lifting polishing device 14 of FIG. 6, and the lifting ball processing for distributing the balls separated by the slats 26 and 41 of the polishing lift 16. It is a detailed sectional view of the tank 40. The outer periphery of the pellet collecting section 25 is covered with a storage tank 44 made of a sheet metal material so as to wrap the pellet collecting section 25. The balls whose pellets and pellets have been separated by the sludge 26 in the lifted-ball processing tank 40 are further guided to the slats 41 which are arranged to incline below the side portions of the slats 26. Since the slats 41 are arranged so as to be inclined, the balls roll so as to be accelerated on the slats 41. The balls and the pellets are separated while the balls are rolling on the snowboard 41, and the pellets are collected by the pellet receiver 39 and flow into the pellet collecting section 25. On the other hand, the separated balls collide with the ball flow path changing member 42 made of a sheet metal material, the direction of the flow is changed, and the balls fall downward.

The balls falling downward are distributed plates 43a and 43b.
Ride on. Since the distribution plates 43a and 43b are inclined, the balls are distributed to the left and right in the drawing and flow. Since the lifted-ball processing tank 40 is provided with a storage tank 44 for storing balls, which is made of a sheet metal material so as to cover the whole from the bottom,
The balls rolled from both ends of the distribution plates 43a and 43b fall on the storage tank bottom portion 45 of the storage tank 44. The storage tank bottom 45 is connected to the left and right mainstream gutters 46a and 46b.

The main flow gutters 46a and 46b are used as prize balls by supplying balls to a ball-playing machine installed in two rows with their backs facing each other. Pipes are connected to the main flow gutters 46a and 46b through mini storage tanks (not shown) arranged corresponding to respective positions in order to supply prize balls to the respective ball game machines. It is for supplying prize balls to the gaming machines, respectively.

If there are more balls pumped by the polishing lift 16 than the number of balls from which the prize balls flow from the mainstream gutters 46a and 46b, the mainstream gutters 46a and 46b become full. Main stream gutter 46a, 4
When 6b becomes full, the ball fills the bottom 45 of the storage tank and rises to the position indicated by the chain double-dashed line in FIG. As shown in FIG. 10, two square tube-shaped ball passages 47 and 48 made of a sheet metal material are arranged at a central position of the storage tank 44.

The height h ₁ of the ball passage 47 is lower than the height h ₂ of the ball passage 48. The area of the lower end half of the ball passage 47 is opened by a lower end opening 49.
9 communicates with the first auxiliary tank guide gutter 50. First
The spare tank guide gutter 50 communicates with the first spare tank 56, and the balls overflowing in the storage tank 44 are in the ball passage 4
It enters from the upper part of 7, flows from the lower end opening 49 to the first auxiliary tank guide gutter 50, and flows into the first auxiliary tank 56 (see FIGS. 4 and 5).

On the other hand, the area of the lower end half of the ball passage 48 forms a lower end opening 51, and this lower end opening 51 communicates with the first island tank guide gutter 52. The first island tank guide gutter 52 leads to the first island tank 115, and the storage tank 4
The ball rising in 4 enters from the upper part of the ball passage 48, flows from the lower end opening 51 to the first island tank guide trough 52, and finally flows into the first island tank 115 (see FIG. 4).

Eventually, the balls that overflow in the storage tank 44 will first flow preferentially to the ball passage 47, and this ball will continue until the spare tank 56 is filled. When the spare tank 56 is full, the storage tank 4
The balls in 4 further increase in volume and rise to the level of the upper end of the going ball passage 48 (see FIG. 9). When the volume of the ball increases to this position, the ball flows into the ball passage 48, flows into the first island tank guide gutter 52, and flows into the first island tank 115.

The balls which have overflowed and flowed into the first auxiliary tank guide gutter 50 enter the vertically arranged first auxiliary tank ball supply pipe 55 (see FIG. 4). Since the first spare tank ball supply pipe 55 is connected to the spare tank 56, the balls enter the spare tank 56 from the first spare tank ball supply pipe 55 and are stored therein. Since the bottom plate 57 of the spare tank 56 is inclined, the balls roll on it.

A ball stopping device ST2 is arranged in the front reserve tank 56 in the rolling direction of the balls. Ball stop device ST2
In the above, the ball stop plate is moved up and down by a motor, and when the ball stop plate rises, the balls are stopped in the spare tank 56. The structure of the ball stopping device ST2 will be described later. On the side surface of the storage tank 44, a ball that overflows on another island is joint 6
Flowed to zero.

It drops from the joint 60 to the ball supply pipe 61 and is connected to the upper end of the forked pipe 62 (see FIG. 5). Oashima 1a
In this case, since the ball from another island is not received at this position, the joint 60 is closed. The joint 59 is a joint connected to the child-parent communication gutter 9, and is for flowing to the child island when the storage tank 44 overflows. However, the parent islands 2a and 3a only receive balls from the child islands 2a and 3b and are closed. In the case of the parent islands 1a and 4a, they are connected to the child islands 1b and 4b, and the balls flow unilaterally.

The bifurcated tube 62 is branched at the lower side, and the discharge port 64,
It constitutes 65. Since the discharge port 64 is connected to the driven-in ball / stored ball outlet gutter 65, the ball is rolled into the ball intake 66. Since the discharge port 65 is connected to the driving ball / stored ball lead-out gutter 67 connected to the spare tank 56, the balls are rolled into the ball inlet 66 of the storage tank 18. Eventually, the balls from other islands are directly collected in the driven-in / stored-ball outflow trough 67 and the ball intake 66, and are pumped by the polishing lift 16 to the lifted-ball processing tank 4
Shipped to 0.

At the outlet of the spare tank 56, a ball stopping device ST2
Are arranged (see FIG. 5). The ball stopping device ST2 is for turning on and off the flow of balls in the spare tank 56 and controlling the flow of the balls into the ball intake 66. Proximity sensors LS3, LS4 for detecting the presence / absence of balls at that position are arranged in the spare tank 56 (see FIG. 4).

When the proximity sensor LS3 detects a ball, the ball stop device ST3 is closed to stop the inflow of balls. When the proximity sensor LS3 cannot detect a ball, the backup tank 56
It means that there are not enough balls, so the ball stop device S
Open T3 and let the balls flow in. That is, priority is given to storing balls in the reserve tank 56 as much as possible.

When the proximity sensor LS4 detects a ball, the ball stop device ST4 is closed to prevent the ball from flowing into another island, and the ball on the own island is given the highest priority to secure the ball.

The upper end of the ball flow path switching tank 110 is connected to the tip of the main flow gutter 46a, but in normal operation, it is partitioned by the shutter 114 and the balls do not flow. Further, since the upper end of the ball channel switching tank 110 is connected to the tip of the first island tank guide gutter 52, the balls overflowed in the storage tank pumping and polishing device 14 pass through the ball channel switching tank 110 to the first island. It flows into the tank 115 and the prize ball counter first tank 74.

First Island Tank 115 and Second Island Tank 123 FIG. 13 is a sectional view taken along the line AA of FIG. FIG. 14 is an enlarged three-dimensional view of the first island tank guide gutter. FIG. 15 is an enlarged view of the first island tank and the second island tank. As shown in FIGS. 13 and 14, the first island tank 11
5 is located near the center of Oshima 2a. The first island tank 115 is a tank having a generally rectangular parallelepiped shape and having an open top for stocking and placing hit balls and accumulated balls hit by a ball game machine. Driving ball guide troughs 116a and 116b are arranged on the left and right of the upper stage of the first island tank 115.

The driving ball guiding troughs 116a, 116b are the driving balls / deriving troughs 117a, 117 with the balls driven from the respective ball game machines arranged on both sides attached to the back surface thereof.
It is a gutter for draining from b. Driving ball guide trough 116a, 1
16b is arranged so as to be inclined, and the outlet 127 at the downstream end thereof is provided.
(See FIG. 15) is arranged so as to directly flow into the second island tank 123.

The balls hit from each ball game machine directly flow into the second island tank 123 and are supplied to the storage tank pumping / polishing device 14 when the ball stopping device ST1 is opened. As will be described later, the ball stop device ST1 is opened with the highest priority, so the balls hit from each ball game machine are supplied to the storage tank pumping / polishing device 14 in priority to the other balls and are circulated for use. It will be. For this reason, the balls are smoothly discharged from the ball game machine without accumulating, there is no clogging that causes a failure, and the customer's game is not hindered.

A first island tank guide gutter 113 is arranged between the driven-in ball / outlet gutter 117a and 117b. The first island tank guide gutter 113 is a gutter for guiding balls to the first island tank 115.

FIG. 14 is a three-dimensional enlarged view of the first island tank guide gutter 113. The first island tank 115 has a generally rectangular parallelepiped shape and is open at the upper side. The first island tank guide trough 113 is inclined in the direction of gravity at the center of the upper part and along the longitudinal direction, that is, at the upper part in the longitudinal direction of the island.

A plurality of openings 118 are arranged along the longitudinal direction of the first island tank 115.
It is for dropping the balls flowing in from the inside. It is better to make the first island tank 115 as large as possible, but in order to increase the capacity of the island, it necessarily becomes a rectangular parallelepiped shape. 1st island tank guide gutter 11 with only opening 118
It is difficult for the ball to drop at the opening 118 at the upstream position of 3 and stochastically drop at the opening 118 at the downstream position. As a result, the distribution of the balls in the first island tank 115 is biased, which hinders smooth movement of the balls.

Therefore, a plane-direction triangular direction changing member 126 is fixed upstream of the opening 118 of the first island tank guide gutter 113. When a ball flows on the first island tank guide gutter 113, a part of the ball drops at the upstream opening 118, but the other balls flow stochastically because the direction changing member 126 obstructs the flow of the ball. Therefore, the balls are uniformly dropped from the openings 118, and as a result, the balls are uniformly dispersed in the first island tank 115.

Both lower ends of the first island tank guide gutter 113 are supported by mounting portions 113a and 113b. Mounting part 11
The mounting positions and heights of 3a and 113b can be adjusted. By this adjustment, the inclination and position of the first island tank guide trough 113 can be changed so that the distribution of the balls becomes uniform in the first island tank 115. .

[Other Embodiments] The lift inspection device of the above-described embodiment is provided on the small lift 119. However, it is obvious that the lift inspection device 170 can be similarly applied to the ball inflow position of the lifting and polishing device 15, the polishing lift 16 and the like, and is also applied to these. Further, although the ball shield plate 180 of the above-described embodiment is provided so as to be swingable, it may be a plug-in type instead of swinging.

Control Operation of Operation Otoshima 2a An operation example of the ball management device 160 will be described below with reference to a flow chart.
FIG. 19 is a flow chart showing the operation of the proximity switches LS1 to LS7 and the ball stopping devices ST1 to ST7 on the parent island 2a.
First, the polishing lift 16 in the Oashima 1a, 2a, 3a, 4a
Main motor 24, sub motor 20, polishing lift 8
The main motor 83 and the sub motor 82 of 0, and the carry motor 125 of the small lift 119 are started. Similarly, child islands 1b, 2b, 3b, 4b and branch islands 1c, 2c, 3c, 4
The transport motor 146 of the small lift 144 of c is started. FIG. 19 is a flowchart showing an outline of the operation of the small lift 119.

When the proximity switch LS7 detects the out-of-stock, the conveyance motor 125 is activated to start the first island tank 115.
The balls are sent to the second island tank 123 located at a high position from. Proximity switch LS at the top of the second island tank 123
When 9 detects the presence of a ball, the transport motor 125 is stopped because the second island tank 123 is full (step P ₂ ). If a ball cannot be detected, wait a short time (5 seconds in this example) to activate the carry motor 125 (step P
₄ , P ₅ ). These controls always operate during the operation of this system and always fill the third backup tank 123.

FIG. 20 is a flow chart showing the ball management operation of the parent island 2a of the ball management device 160. Ball management device 160
Starts the following control operation. When the proximity switch LS1 in the storage tank 44 detects a ball break, the ball stop device ST1 is irrespective of the detection signal state of the proximity switch LS2.
And open the ball stop plate of the ball stop device ST2 (step P
₄ , P ₇ ).

The balls enter the driven-in ball / stored ball lead-out gutter 65 and the ball inlet 66 from the second island tank 123, and are pumped to the upper storage tank 44 by the polishing lift 16. At the same time, the ball stopping device ST2 is opened, and the balls are introduced from the first preliminary tank 56 and supplied to the ball polishing lift 16.

When the proximity switch LS1 is not out of balls and the proximity switch LS2 is not out of balls, that is, when the storage tank 44 is not full, the ball stop device ST1 is open and the ball stop device ST2 is closed to close the first preliminary tank. Prevent the flow of balls from 56 (steps P ₅ , P ₈ ). When the proximity switch LS1 and the proximity switch LS2 are not out of balls, that is, when the storage tank 44 is full, both the ball stop devices ST1 and ST2 are closed.

From the above operation, when the ball stop device ST1 is opened, the balls from the second island tank 123 are mainly taken in preferentially, and the balls are sent to the storage tank 44 by the polishing lift 16 and used as prize balls. Means that. Next, it is determined whether or not the proximity switch LS3 detects a ball. If the proximity switch LS3 cannot detect a ball, the ball stop device S
T3 (see FIG. 5) is opened and the balls from the upper part of the ball passage 47 are taken into the first preliminary tank 56.

If the proximity switch LS3 detects a ball, that is, if the first auxiliary tank 56 is full, the ball stop device ST3 is closed to stop the inflow of balls from the storage tank 44. Next, when the proximity switch LS4 detects a ball, that is, when the first spare tank 56 is not full, it means that there is a shortage of balls on this island, so the ball stop device ST4 is opened and the joint 60 is used. And prepare to be able to introduce balls from the neighboring Kojima 2b.

FIG. 21 is a flow chart of signal processing in the child island 2b of the ball-less signal a output from the proximity switch LS4.
When the proximity switch LS4 from the parent island 2a detects a ball, that is, when the first reserve tank 56 in which the ball is preferentially stored is not full, it means that the parent island 2a is short of balls. Therefore, the ballless signal a is sent to the adjacent island, Kojima 2b.

At Kojima 2b, a ballless signal a is received (see FIG. 1).
A reference), the state (P ₂₀ of the proximity switch LS13), that is, the second island tank 148 for detecting a state of whether or not full. Second if the proximity switch LS13 can detect the ball
Since the island tank 148 is full, the ball stop device ST11
And the ball stop device ST12 is opened. Proximity switch LS13
If no ball can be detected, there is not enough balls in the second island tank 148, and there is no room to send the ball to the parent island 2a. Therefore, the ball stop device 14 is closed and the ball is placed on the adjacent parent island 2a. takes precedence over the Jishima so as not to go (P _21).

Next, as shown in FIG. 20, the presence or absence of a ball is detected by the proximity switch LS5 of the first island tank guide gutter 113 (P ₁₆ ). The detection of the presence or absence of a ball by the proximity switch LS5 is a detection of whether or not there is room in the first island tank 115 to receive a ball from another island. When the proximity switch LS5 cannot detect a ball, the ball stop device ST5 is opened to accept the ball from the lifting and polishing device 15. When there is no room to accept the ball closes the ball stopping device ST5 (step P _17).

As shown in FIG. 22, finally, the proximity switch LS6 of the pumping-up ball processing tank 95 detects the presence or absence of balls. When a ball is detected at this position, it is determined that the ball is full on this island, and the ball stop device ST6 of the lifted-ball polishing device 15 is closed. Next, the proximity switch LS7 detects whether or not the amount of balls in the second island tank 123 is a predetermined amount. The small amount of balls in the second island tank 13 means that the first island tank 1
Since the number of balls in 15 is also insufficient and the amount of balls on the parent island 2a is insufficient, a ball-less signal b (see FIG. 1) is issued to secure the amount of balls on the own island, and the balls on the island 2b Stop device ST13
And closing the Edato 2c ball stop device ST13 (not _{shown) (P 29, P 30)} .

Control Operation of Child Island 2b FIG. 23 is a flow chart showing the outline of the control operation of the child island 2b . Small lift 1
The transport motor 144 of 44 is also operated by the same operation as the parent island 2a. When the proximity switch LS11 in the upper storage tank 150 detects a ball break, the proximity switch LS
Regardless of the detection signal state of 12, the ball stop plate of the ball stop device ST11 and the ball stop device ST12 is opened (step P
₄ , P ₇ ).

The balls are transferred from the second island tank 145 to the upper storage tank 150 by a polishing lift. At the same time, the ball stopping device ST12 is opened, and balls are introduced from the spare tank 148 and supplied to a ball polishing lift (not shown).

When the proximity switch LS11 is not out of balls and the proximity switch LS12 is not out of balls, that is, when the storage tank 150 is not full, the ball stopping device S
T11 is opened and the ball stopping device ST12 is closed to prevent the inflow of balls from the reserve tank 148 (step P ₅ ,
P ₈ ). Proximity switch LS11 and proximity switch LS1
When 2 is not out of balls, that is, when the storage tank 150 is full, both the ball stopping devices ST11 and ST12 are closed.

From the above operation, opening of the ball stopping device ST11 means that the balls from the second island tank 145 are mainly used with priority. Next, it is determined whether or not the proximity switch LS13 of the spare tank 148 detects a ball. If the proximity switch LS13 detects a ball, that is, if the spare tank 148 is full, the ball stop device ST13 is closed to stop the flow of the ball from the storage tank 150. Next, when the proximity switch LS14 detects a ball, that is, when the spare tank 148 is not full, it means that there is a shortage of balls on this child island 2b, so the ball stop device ST14.
To open the ball so that the ball can be introduced from the adjacent one block, Kojima 1b.

FIG. 23 is a flow chart of signal processing of the ballless signal c (see FIG. 1) output from the proximity switch LS14 in the child island 1b. When the proximity switch LS14 from the parent island 2a detects a ball, that is, when the reserve tank 148 in which balls are preferentially stored is not full, it means that there is a shortage of balls on this child island 2b. The ballless signal c is sent to the neighboring island, Kojima 1b.

When the child island 1b receives the ballless signal c, the state (P) of the proximity switch LS19 (not shown) of the child island 1b is detected.
₂₀ ), that is, the state of whether or not the second island tank 145 is full is detected. If the proximity switch LS19 can detect a ball, the second island tank 145 is full of balls, so the ball stop device ST11 and the ball stop device ST12 are opened. If the proximity switch LS19 cannot detect a ball, there is not enough balls in the second island tank 145, and there is no room to send balls to the child island 2b. Therefore, the ball stop device ST14 is closed and the adjacent child island is closed. Prioritize the island so that the ball does not go to 2b (P
₂₁ ).

Next, the presence / absence of a ball is detected by the proximity switch LS15 arranged above the first island tank 143 of the child island 2b (P ₁₆ ). The detection of the presence or absence of a ball by the proximity switch LS15 is a detection of whether or not there is room in the first island tank 115 to receive a ball from another island. Proximity switch LS
When 15 cannot detect the ball, it opens the ball stopping device ST15 and accepts the ball from the parent island 2a. When there is no room to accept the ball closes the ball stopping device ST15 (step P _17).

Next, the proximity switch LS19 detects whether the amount of balls in the second island tank 145 is a predetermined amount. The fact that the number of balls in the second island tank 145 is small means that there is a shortage of balls in the child island 2b, so a ball-less signal j (see FIG. 1) is issued to secure the balls in the own island. Oshima 2
Ball stop device ST7 of a and ball stop device ST1 of branch island 2c
3 (not shown) is closed (P ₂₄ , P ₂₇ ).

The above is the outline of the operation of the child island 2b, and the other child islands 1b, 3b and 4c are also the same, and the description thereof will be omitted.
The islands 1c, 2c, 3c and 4c also perform the same operations as the child islands, and their explanations are omitted.

Operation between Blocks FIG. 26 is a flow chart for managing the overall flow. Proximity switch LS4 on Oshima 1a
Is out of balls, that is, it is determined whether or not there is a shortage of balls in the first spare tank 56 (having the same structure as the parent island 2a).

If it is not out of balls, the process proceeds to step P ₄ . If there is a shortage of balls, it is determined that there is a shortage of balls in this block 1, and a no-balls signal d indicating that there is a shortage of balls is transmitted to the proximity switch LS7 of the three blocks. All the proximity switches LS7 of the one block child island 3b, the parent island 3a, and the branch island 3c which received the ballless signal d are switched to the ballless signal d. As a result, the proximity switch LS7 shown in FIG. 22 produces the same signal as in the ballless state, and the surplus balls produced as a result are transferred from the parent island 3a to the parent island 1a.
Feed the balls through the parent-parent supply gutter 11.

At the same time, the no-ball signal d activates the ball stopping device ST7 (having the same structure as the parent 2a) of the parent island 1a so that the balls can be fed through the parent-parent supply trough 11. Next, Oshima
If the proximity switch LS6 of the ball processing tank 95 of a is full, it is determined that the number of balls in the block 1 is excessive and a full signal e is output to the child island 2b. When the full signal e is transmitted, the ball stopping device ST14 of the child island 2b is opened to allow excess balls to be supplied from one block to two blocks through the inter-island block connection gutter 8.

Next, the proximity switch LS6 of the parent island 2a (see FIG. 2)
As shown in 2, it is also used to control the ball stopping device ST6. ) Is issuing a full signal f, this signal is transmitted to Oshima 4a. When the full signal f is transmitted, it means that the two blocks of balls are full, and therefore the ball stop device S is provided in order to supply the balls from the parent island 2a to the parent island 4a.
Open T7.

Similarly, the parent island 4a transmits the no-ball signal g, the excess ball signal h, and the parent island 3a transmits the excess ball signal i to manage the state of the balls between them.

[Other Embodiments] The lift inspection device of the above embodiment was provided on the small lift 119. However, it is obvious that the lift inspection device can be similarly applied to the ball inflow position of the lifting and polishing device 15, the polishing lift 16 and the like, and is also applied to these.

In the above embodiment, the function of the lifting and polishing apparatus 14 first fills the main flow gutters 46a and 46b, and then fills the backup tank 56. The balls which have filled the spare tank 56 and overflowed further fill the first island tank 115 and the prize ball counter first tank 74 via the first island tank guide gutter 52.

However, the balls from the lifting and polishing apparatus 14 do not have to flow into the prize ball counter first tank 74, but may flow into only the first island tank 115. The prize balls from the prize ball counter 5 described above may be stored in the prize ball counter first tank 74 and the prize ball counter second tank 78.

Although the ball management device of the above embodiment uses the sequencer, the same control may be realized by using a relay circuit. Further, the ball management device operates various programs sequentially in a time division manner, but a plurality of control devices may be used. Further, although the ball stopping device is of a type driven by a motor, it may be of a type driven by a solenoid instead of the motor.
