That is, each part constituting the cleaning device 17 including the rectifying member 54, the passage member 55, and the relay member 92 is in a non-contact state with the game island stand 1 'and various members and devices disposed therein. It is arranged in the lower part of the gaming island 1 'so that the swing of the entire device is not transmitted to the surroundings and does not adversely affect the surrounding various members and devices.

The pachinko balls collected in the collecting gutter portion 15 flow down the discharge gutter 15a, fall below the discharge portion 91, and further flow into the ball passage portion 25 through the storage portion 53 of the rectifying member 54. After passing through the ball passage portion 25, it passes through the passage member 55 and the relay member 92 and is discharged into the lower tank 16.

As shown in FIG. 6, the rocking plate 32 constituting the ball passage 25 is provided with a bearing at the upper end of an eccentric member 38 eccentric with respect to the rotating shaft 36 of the motor 35 as described above. The eccentric member 38 is eccentrically rotated when the rotating shaft 36 is rotated by driving the motor 35, as described later, because the eccentric member 38 is mounted on the supporting member 42 which is mounted to be relatively rotatable via 43. The plate 32 is swung in the horizontal direction. With the horizontal swing of the swinging plate 32, each pachinko ball placed on the upper surface of the sheet member S is rotated and its surface is rubbed against the sheet member S, and passes through the ball passage portion 25. During this operation, dirt, dust and the like adhering to the surface of the pachinko ball are wiped off by the sheet member S and cleaned.

The oscillating plate 32 formed in a substantially elongated rectangular shape in a plan view is provided with a support member 42 slidably supported on a pedestal 44 on an upper surface of a support plate 33 fixed on the base portion 24.
, The lower surface is supported over a wide area, and the four lower corners are urged toward the support board 33 by the tension springs 47, so that the vertical bulging generated at the end of the swing plate 32 is suppressed. Thus, the swing plate 32 is smoothly and stably horizontally swung. Therefore, since the pachinko balls are surely brought into sliding contact with the sheet member S without greatly jumping, the cleaning action is not reduced.

Further, since the sheet member S is pressed against the rubber sheet 48 by the weight of the pachinko balls, the horizontal swing of the swinging plate 32 is effectively transmitted to the sheet member S, so that the cleaning action is enhanced, and The contact noise or the like generated by the movement is suppressed.

Although not shown, the swing plate 32 in the present embodiment is disposed so as to be slightly inclined upward in the direction of movement of the pachinko ball.
The pachinko balls that have flowed into the upper portion 2 are retained on the rocking plate 32 for a predetermined time and are cleaned. Most of the pachinko balls are pushed out by the pachinko balls that flow from the upstream side, are moved downstream, and are discharged to the lower tank 16. Will be done.

Next, the contents of drive control of the motor 35 as swing means in the cleaning device 17 of this embodiment will be described.

As shown in FIG. 15, a proximity sensor 93 electrically connected to a control unit (not shown) provided in the control unit 89 is provided at a predetermined height position on the side wall of the rectification member 54 that forms the storage unit 53. When the proximity sensor 93 detects that a predetermined amount of pachinko balls have been stored in the storage unit 53, the control unit rotates the rotating shaft 36 of the motor 35 clockwise or counterclockwise. It is designed to rotate in that direction. Note that such a control program is registered in advance in a storage unit (not shown) or the like, and the control unit executes control based on the program stored in the storage unit. The storage unit stores the rotation direction of the rotating shaft 36 when the motor 35 is driven.

Here, the details of the drive control of the motor 35 by the control unit in the control unit 89 will be described in detail with reference to the flowchart shown in FIG. 17. First, in Sa1, the proximity sensor 93 outputs a pachinko ball detection signal. It is determined whether or not there is an output, and if there is an output, S
Proceeding to a2, counting by the timer in the control unit is started. In Sa3, it is determined whether or not the output of the pachinko ball detection signal has continued for a predetermined time (for example, 10 seconds) or more. If it is determined that the output of the pachinko ball detection signal has continued for 10 seconds or more, which is the predetermined time, Sa4. Proceed to. Also, Sa
If it is determined in step 3 that the output of the pachinko ball detection signal has not been continued for 10 seconds or more, the process returns to Sa1 again. Sa
In step 4, the rotation direction data of the rotary shaft 36 at the time of the previous driving of the motor 35 is called from the storage unit, and it is determined whether or not the previous rotation direction of the rotary shaft 36 was right rotation. If it is determined, the process proceeds to Sa5 to rotate the rotation shaft 36 to the left. If it is determined that the rotation is not to the right, that is, to the left, the process proceeds to Sa10 to rotate the rotation shaft 36 to the right and proceeds to Sa6. By driving the motor 35 in this manner, the swinging plate 32 is horizontally rotated in the clockwise or counterclockwise direction, and the cleaning of the pachinko balls is started.

In Sa5 or Sa10, the motor 3
After the drive of No. 5 is started, it is determined again whether there is an output of a pachinko ball detection signal from the proximity sensor 93 in Sa6, and only when it is determined that there is no output, the process proceeds to Sa7 to start counting by the timer. I do. In Sa8, it is determined whether or not the state in which the pachinko ball detection signal is not output has continued for a predetermined period of time (for example, 10 seconds).
Proceeding to a9, the drive of the motor 35 is stopped, and the cleaning of the pachinko balls is completed. If it is determined in Sa8 that the state in which the pachinko ball detection signal is not output has not been continued for 10 seconds or more, the process returns to Sa6, and the driving of the motor 35 is continued.

When the motor 35 is driven based on such a control program, the motor 35 is driven when the pachinko balls have stayed in the ball passage 25 to some extent, and the rocking plate 32 is rocked. Since the pachinko balls are cleaned, the pachinko balls can be efficiently cleaned without driving the motor 35 uselessly compared to the case where the motor 35 is constantly driven during business hours. become. In Sa3 and Sa8 described above, the time for detecting the presence / absence of the output of the detection signal of the pachinko ball can be variously changed, and is not limited to 10 seconds.

As described above, the cleaning device 17 in this embodiment is
In this configuration, the horizontal rotation direction of the swinging plate 32 is alternately switched, so that the pachinko balls are eccentrically retained at a predetermined position on the swinging plate 32, and the predetermined position of the sheet member S is contaminated. Is not locally attached, so that the entire surface of the sheet member S can be effectively used. Further, particularly in the case where the sheet member S is laid out on the rocking plate 32 so as to be able to be pulled out as in the present embodiment, the displacement of the sheet member S due to the horizontal rotation of the rocking plate 32 is less likely to occur.

The driving and stopping of the motor 35 as a swinging means for horizontally rotating the swinging plate 32 are automatically performed based on the detection result of the pachinko ball by the proximity sensor 93, and the motor 35 When the motor 35 is driven once after the driving of the motor 35 is stopped, the rotating shaft 36 is set in advance so as to rotate in a direction opposite to the rotating direction at the time of driving the motor 35 last time. The swinging direction of the swinging plate 32 is switched without performing any load and without applying a load to the motor 35.

In the present embodiment, the horizontal rotation direction of the swinging plate 32 is automatically and alternately switched with the driving and stopping of the motor 35. If the horizontal rotation direction of the moving plate 32 can be switched, although not particularly shown, for example, a drive switch of the motor 35 in which the rotation shaft 36 rotates clockwise and a drive switch of the motor 35 in which the rotation shaft 36 rotates left are Each set up,
By selecting and turning on one of the drive switches, the swing plate 32 may be rotated horizontally in the clockwise or counterclockwise direction. Needless to say, the rotation direction of the rotating shaft 36 may be switched automatically or by a changeover switch while the motor 35 is being driven.

Further, the switching of the rotating direction of the rotating shaft 36 is performed at predetermined intervals, or when the rotating speed of the rotating shaft 36 reaches a predetermined predetermined rotating speed. It may be performed. In this case, if the forward rotation and the reverse rotation are performed at substantially the same time or at the same rotation speed, the displacement of the sheet member S and the like are effectively corrected.

In the present invention, it is also possible to control the motor 35 to be driven at a predetermined time interval, for example, at a predetermined time interval, etc., and it is particularly limited to the drive control using the proximity sensor 93. It is not something to be done.

The control section for driving the motor 35 stores the total drive time of the motor 35 in the storage section (not shown) based on a program having predetermined contents, and controls the total drive time of the motor 35. The driving of the winding motor 68 is executed as follows based on the time.

Here, the control contents of the winding motor 68 are shown in FIG.
First, in Sb1, the control unit determines whether or not the driving of the motor 35 has been started. If it is determined that the motor 35 has been driven, the control unit starts counting the driving time and proceeds to Sb2. Proceeds and returns to Sb1 if not driven. In Sb2, the motor 3
It is determined whether or not the total drive time of No. 5 has reached a predetermined time previously registered in the storage unit, and if it is determined that the predetermined time has been reached, the process proceeds to Sb3 to drive the winding motor 68, and When it is determined that the time has not reached, the process returns to Sb2.

When the take-up motor 68 is driven in Sb3, the roller 8 is detected via the detection sensor 88 in Sb4.
In addition to the detection of the number of rotations of 2, the rotation proceeds to Sb5 when the rotation is detected, and the number of rotations (here, the sheet member S for the longitudinal width of the swing plate 32 is It is determined whether or not the number of revolutions required for drawing out) has been reached. If it is determined that the previously registered number of revolutions has been reached, the process proceeds to Sb6, and at Sb5, the number of revolutions previously registered has been reached. If it is determined that there is not, the process returns to Sb4 again.

If the rotation of the roller 82 is not detected in Sb4, as described above, the upper front edge of the arm 83 comes into contact with the stopper 90, and the swing of the arm 83 toward the mounting pipe 59 is restricted. Since the roller 82 is separated from the sheet member S, the control unit determines whether the remaining amount of the sheet member S wound around the core member 58 is low or the rotation of the detection sensor 88 or the roller 82 is insufficient. It is determined that an error has occurred, and this is output to an external management computer or the like in Sb8 to notify that the time to replace the sheet member S is approaching or that an error due to a malfunction or the like has occurred.

In Sb6, the rotation shaft 64 is reversely rotated by a pre-registered rotation amount (for example, one rotation), and the process proceeds to S7. Then, the driving of the winding motor 68 is stopped, and the sheet member S is pulled out. To end.

When the take-up motor 68 is driven based on such a control program, as shown in FIG. 7, the mounting tube 59 rotates around the axis and the new sheet member S wound around the core member 58. Is pulled out to the upper surface of the rubber sheet 48 of the rocking plate 32, and the dirty sheet member S, which has been laid on the rocking plate 32, is attached to the winding tube 61 so as to be relatively non-rotatable. It is compactly wound around the outer periphery of the material 60.

That is, when the sheet member S becomes dirty to some extent, the new sheet member S is laid on the ball passage 25, so that the cleaning action of the pachinko balls is prevented from being reduced. Also,
Since the soiled sheet member S is wound around the core member 60 and accommodated compactly, the core member 58 is moved from the mounting tube 59 to
The sheet member S can be easily replaced simply by extracting the core member 60 from the winding tube 61.

The take-up motor 68 is controlled so as to be driven only when the motor 35 is driven, and when the pachinko ball is rotated by the horizontal swing of the swing plate 32, the sheet member is rotated. Since the S is drawn out, the frictional resistance generated between the sheet member S and the pachinko balls and between the sheet member S and the rubber sheet 48 at the time of drawing out is reduced, and the sheet is laid on the rocking plate 32. Even when the pachinko balls are placed on the sheet member S, the sheet member S can be pulled out with a relatively small force, so that no load is applied to the winding motor 68.

In the present embodiment, the rotation of the rotary shaft 69 is stopped when the sheet member S for the longitudinal width of the ball passage portion 25 is pulled out. The length of the sheet member S can be arbitrarily changed.
May be drawn.

Further, the rotation shaft 69 of the take-up motor 68 is slightly reversed at the time when the sheet member S of a predetermined length is pulled out, so that the swing plate 32
A slight play occurs in the sheet member S laid thereon, and the sheet member S easily swings together with the swing plate 32, and the sliding action with the pachinko balls is improved, so that the cleaning action is improved.

Further, the winding motor 68 in this embodiment is
Is driven when the drive time of the motor 35 reaches a predetermined time.
Irrespective of the drive time, the control may be performed such that the drive is performed at predetermined time intervals.

Then, the sheet member S by the winding motor 68
The roller 82 provided so that the drawing length of the roller 82 contacts the sheet member S mounted on the mounting pipe 59 as described above.
The rotation is measured based on the amount of rotation detected by a detection sensor 88 capable of detecting the rotation of the sheet motor. Therefore, the sheet can be controlled with a simpler control than when the rotation of the rotation shaft 69 of the winding motor 68 is detected. The member S can be pulled out by a predetermined length. Further, since the roller 82 is provided so as to come into contact with the sheet member S mounted on the mounting tube 59, the length of the drawn-out member actually drawn out to the ball passage portion 25 is detected. Even if the member S is distorted, bent, or the like, the sheet member S can be accurately drawn out by a predetermined length without being affected by the occurrence.

Further, if the rotation of the roller 82 is not detected while the take-up motor 68 is being driven, the control unit
It is determined that the sheet member S wound around the core member 58 is small, or that the detection sensor 88 or the roller 82 is malfunctioning, for example, a management computer in the hall, Alternatively, since an error signal is output to a display device or the like provided at a predetermined position on the game island stand 1, the sheet member S continues to be cleaned in a dirty state, and the cleaning action may be significantly reduced. Absent.

Since the pachinko balls are gradually cleaned while moving on the ball passage 25 to the downstream side, the sheet member S is basically more likely to be stained on the upstream side than on the downstream side. Therefore, the winding tube 6 rotated by the winding motor 68
By providing 1 on the upstream side in the ball passage section 25,
Since the sheet member S is taken up from a portion with a high degree of contamination, the sheet member S can be used efficiently.

The core members 58 and 60 of the sheet member S are
Attachment tube 59 and take-up tube 6 of attachment unit 26 attached to base 24 so as to be slidable in the horizontal direction.
3, it is possible to remove the waist plate 7 and open the lower part of the game island stand 1 'as shown in FIG. 3, and the mounting unit 26 is moved to the near side as shown by a two-dot chain line in the figure. Only by sliding, the replacement or maintenance of the sheet member S can be easily performed outside the game island stand 1 '.

Note that the collection gutter 15 in this embodiment is
As shown in FIGS. 14 and 16, an overflow gutter 15 b for guiding the pachinko balls directly to the lower tank 16 is formed on the opposite side of the discharge gutter 15 a for guiding the pachinko balls to the cleaning device 17. Drain gutter 1
When the pachinko balls accumulate to the upstream side of 5a, the newly collected pachinko balls fall from the hole 16b formed on the upper surface of the lower tank 16 via the overflow gutter 15b. Therefore, even if, for example, a large amount of pachinko balls are collected in a short time or the motor 35 of the cleaning device 17 breaks down, the circulation of the pachinko balls does not stop.
