As described above, the tensioning device 50 can control the drive of the motor 62 by the looseness detection sensor 59 to always keep the tension of the cloth belt 18 constant. The driving of the motor 62 of the tensioning device 50 is performed by turning the looseness detection sensor 59 from ON to OFF.
Is continued for a predetermined time even after the switching to the state shown in FIG. This is because the looseness detection sensor 59 is ON as in the related art.
When the drive of the motor 62 is stopped at the timing of switching from the state to the OFF state, the ON / OFF of the looseness detection sensor 59 is switched by the slight extension of the cloth belt 18, so that the motor 62 is frequently driven or stopped. Therefore, the efficiency is low, and the life of the motor 62 is adversely affected. Further, it is desirable that the above-described operation of the tension device 50 be performed even when the power is turned on at the start of business. This is because the cloth belt 18 may be stretched at night due to the weight or humidity of the tensioning device, so that the cloth belt 18 may or may not be detected by the looseness detection sensor 59 for a predetermined time (for example, one second).
This is because it is desirable to drive the degree motor 62.

However, as described later, when the stopper piece support rod 99 is pushed forward by the eccentric cam 101 and moves forward as shown in FIG. 15, the stopper piece support rod 99 is further compressed by the rubber piece 111.
Moves forward, the support shaft 105 is located on the far side (right side in the figure) of the elongated hole 97a. Note that a spring, a spring, or a synthetic resin may be used as the elastic member.

Therefore, in the present embodiment, when the driving of the motor 103 (see FIG. 14) is stopped as described later, the motor 103 must be stopped in any process in which the rubber piece 111 is elastically deformed. Therefore, the stop timing of the motor 103 can have a certain width.

Next, a mechanism for sliding the holding piece 116 back and forth will be described. As shown in FIGS. 14 and 15, a motor 103 is mounted on one side and outside of the mounting box 96, and an output shaft of the motor 103 is rotatably supported behind the holding piece 116 via the gear 102. Connected to one end of the rotating shaft 100. That is,
The rotating shaft 100 is configured to be rotated by driving a motor 103. A pair of eccentric cams 101 are fixed to the rotating shaft 100 at predetermined intervals, and a pressing piece 1 provided at the rear end of the holding piece 116 is provided.
12 is pressed. Then, motor 1
03 is driven, the rotary shaft 100 and the eccentric cam 101 fixed to the rotary shaft 100 as shown in FIG.
Is rotated and presses the pressing piece 112 provided at the rear end of the holding piece 116, so that the holding piece 116 moves forward, and the cloth belt 18 is brought into a chucking state by the holding piece 116 and the holding table 107. Become. And the motor 103
When the eccentric cam 101 is rotated in the reverse direction, the eccentric cam 101 rotated in the reverse direction is no longer in a state of pressing the holding piece 116, as shown in FIG.
The holding piece 116 is moved rearward by the urging force of 10, and a gap is formed between the holding table 107 and the holding piece 116, and the cloth belt 1
8 is in a non-chucking state.

The driving stop control of the stopping device 80 as described above is performed by the state detecting sensor 1 for detecting whether or not the holding piece 116 is chucking the cloth belt 18.
14, 115. The state detection sensors 114 and 115 will be described with reference to FIGS. In the figure, a contact piece 113 formed in an inverted L-shape is attached to one upper end of a holding piece 116. The open state detection sensor 114 is attached to the inner surface of the mounting box 96 corresponding to the position where the contact piece 113 has moved to the near side (the left side in the figure), and the contact piece 113 is moved to the far side (the right side in the figure). The closed state detection sensor 115 is attached corresponding to the position moved to ()). Although not shown in detail, the open state detection sensor 1
14 and the closed state detection sensor 115 are attached to the mounting box 96.
Since it is fixed to a long hole (not shown) formed on the side surface with a screw, even if the mounting position is shifted due to long-term use, it can be easily readjusted to an appropriate position. When the contact piece 113 moves back and forth, the open state detection sensor 114 and the closed state detection sensor 115 press the projections 114b and 115b of the microswitch by the detection pieces 114a and 115a protruding below the contact piece 113, respectively. This is for detecting whether or not the holding piece 116 is chucking the cloth belt 18.

Next, the operation of the open state detection sensor 114 and the closed state detection sensor 115 will be described. First, as shown in FIG. 11, when the holding piece 116 moves rearward to form a gap between the holding table 107 and the holding piece 116 and the cloth belt 18 is in a non-chucking state,
The contact piece 113 contacts the detection piece 114a and the protrusion 114b
Is pressed, the open state detection sensor 114 detects that the cloth belt 18 is in the non-chucking state. Also, as shown in FIGS.
When the fabric belt 18 is moved forward and the cloth belt 18 is held between the holding table 107 and the holding piece 116 and is in a chucking state, the contact piece 113 contacts the detection piece 115a and the protrusion 115b is pressed. Therefore, the closed state detection sensor 11
5, it is detected that the cloth belt 18 is in a chucking state. As described above, when the open state detection sensor 114 and the closed state detection sensor 115 detect the chucking state and the non-chucking state of the cloth belt 18, the state signal is output to the outside via the cord 104. Then, the driving of the motor 103 is stopped. Therefore,
By detecting that the holding piece 116 is in either the holding state or the opening state, the motor for driving the holding piece 116 can be stopped and controlled.

It should be noted that the ball polishing cloth belt automatic winding mechanism according to the present embodiment has a motor 10 for driving the holding piece 116.
3 is provided with a timer (not shown) for measuring the drive time, and when the predetermined time is measured by the timer, the drive of the motor 103 is stopped and an abnormal signal is output to the outside. However, details of such control will be described later.

Further, the stopping device 80 is connected to the storage device 17.
It is possible to detect that the roll-shaped cloth belt 18 is completely used and notify the outside to the outside. The configuration and operation for this will be described with reference to FIG.
This will be described with reference to FIGS.

As shown in FIG. 8, rocking piece support members 89 are provided on both front sides of the cover 83, and one end of the rocking piece support member 89 is always in contact with the cloth belt 18. The cloth belt contact piece 117 is pivotally supported so as to freely swing. The cloth belt contact piece 117 is provided on the swinging piece support member 89.
And a connecting shaft 92 and a supporting shaft 91 for connecting these to each other. A cylindrical loose fitting tube 92a is fitted into the connecting shaft 92 so as to always contact the cloth belt 18.
The support shaft 91 has a role as a swing support shaft of the cloth belt contact piece 117. A position detection sensor 93 for detecting the contact of the connection shaft 92 of the cloth belt contact piece 117 is attached inside the front central part of the cover body 83. The position detecting sensor 93 has a detecting piece 94 protruded so as to come into contact with the swinging piece 90.
Is pressed to detect the position of the cloth belt contact piece 117. The cloth belt 18 stored in the storage device 17 is connected to the connection shaft 92a of the cloth belt contact piece 117.
As described above, the stopper is inserted through the upper surface of the cover body 83 into the cloth belt insertion portion 82 formed on the upper part on the rear side of the stopping device 80, and is wound around the guide rail cover 9.

The operation of the stop device 80 configured as described above will be described with reference to FIGS. First, in a normal state, as shown in FIG. 9, one end of the cloth belt contact piece 117 that comes into contact with the cloth belt 18 is pulled up by the tension of the cloth belt 18 wound around the Since the contact piece 117 is held vertically, the contact of the rocking piece 90 is detected by the position detection sensor 93. However, when the cloth belt 18 stored in the storage device 17 has been used up to the end and its end is released from the winding portion of the storage device 17, as shown in FIG. Since the tension of the belt 18 is loosened and one end of the cloth belt contact piece 117 that comes into contact with the cloth belt 18 cannot be pulled up, the cloth belt contact piece 117 swings forward. Then, since the position detection sensor 93 does not detect the contact of the swinging piece 90, a signal to that effect is led out. Therefore, the stopping device 80 according to the present embodiment can detect that the cloth belt 18 of the storage device 17 has been used to the end, notify the outside, and prompt the replacement of the cloth belt 18.

While the structure and operation of the automatic polishing mechanism for a ball polishing cloth belt according to the embodiment have been described above, the automatic operation of the cloth belt 18 by the automatic winding mechanism for a ball polishing cloth according to the embodiment will now be described. The winding control will be described with reference to FIGS. FIG. 16 is a flowchart showing the automatic winding control of the cloth belt 18 by the ball polishing cloth belt automatic winding mechanism according to the embodiment, and FIG.
FIG. 18 is a flowchart showing the contents of the automatic winding process in the automatic winding control of FIG. 8, and FIG. 18 is a flowchart showing the contents of the holding process of the cloth belt 18 by the stopping device 80;
FIG. 20 is a flowchart showing the contents of the opening process of the cloth belt 18 by the stopping device 80, and FIG. 20 is a flowchart showing the contents of the abnormality confirmation processing in the automatic winding control of the cloth belt 18.

First, the outline of the automatic winding control of the cloth belt 18 will be described with reference to FIG. In the ball-polishing cloth belt automatic winding mechanism according to the embodiment, the cloth belt 1
The automatic winding control 8 is performed by a management computer (not shown) installed outside. Normally, at the end of a business day in a game arcade or the like, the cloth belt 18 is in a contaminated state by driving the doffing and conveying device 1, and the contaminated portion is replaced with an unused portion. There is a need. In such a case, in step 10, an automatic winding signal is output from the management computer to a control board (not shown) of the doffing and feeding device 1. Then, in step 11, the automatic winding signal is automatically wound from the control board of the doffing and feeding device 1 to the winding device 30, the tension device 50, and the stopping device 80 constituting the ball polishing cloth belt automatic winding mechanism. A pick-up operation signal is output. The automatic winding operation of the cloth belt 18 by the ball polishing cloth belt automatic winding mechanism is started in step 12 in response to the automatic winding operation signal. The contents of the automatic winding processing will be described later. Next, at step 13, an abnormality confirmation process is performed on each part constituting the ball polishing cloth belt automatic winding mechanism. The details of the abnormality confirmation processing will also be described later. Then, after the abnormality confirmation process is performed,
In step 14, an automatic winding completion signal is output from a control board (not shown) of the doffing and feeding apparatus 1 to a management computer (not shown), and the cloth belt 18 is automatically wound by the ball polishing cloth belt automatic winding mechanism. Control ends.

Next, the content of the automatic winding process of the cloth belt 18 by the ball polishing cloth belt automatic winding mechanism in step 12 will be described with reference to FIG. Cloth belt 18
Is started, in step 20, it is determined whether or not the position detection sensor 93 provided in the stopping device 80 is ON. As described above, the position detection sensor 93 detects whether or not the cloth belt 18 of the storage device 17 has been used to the end, and the cloth belt 18 is always held vertically by the tension of the cloth belt 18. Although the ON state is detected by detecting the contact of the belt contact piece 117, when the end of the cloth belt 18 is released from the storage device 17, the tension is loosened and the cloth belt contact piece 117 swings forward. Then, the contact of the cloth belt contact piece 117 is not detected, and the cloth belt contact piece 117 is turned off. Therefore, step 20
If it is determined that the position detection sensor 93 is in the OFF state, the cloth belt 18 of the storage device 17 needs to be replaced. Therefore, in step 21, a cloth belt replacement signal is output to the outside. I have. In response to the cloth belt exchange signal, an indicator lamp (not shown) is turned on, or a management computer (not shown) is displayed so as to prompt the store clerk of the game arcade to replace the cloth belt 18 of the storage device 17. be able to. As described above, when the cloth belt 18 is replaced in step 22, it is determined again in step 20 whether the position detection sensor 93 is ON.

If it is determined in step S20 that the position detection sensor 93 is ON, then in step S23, counting of a timer (not shown) for measuring the driving time of the tension device 50 is started. And the pressing roller 65 by the slip detection sensor 72 of the pulling device 50.
The counting of the number of rotations is started. The timer allows the tensioning device 50 to be driven until a predetermined time (for example, 3 minutes) required to replace the contaminated portion and the unused portion of the cloth belt 18 has elapsed. Further, as described above, the slip detection sensor 72 can detect the rotation speed of the screw 71 embedded in the pressure contact roller 65 and thereby determine the rotation speed of the pressure contact roller 65. Until a predetermined value is reached.
Can be driven. After the timer (not shown) and the count of the slip detection sensor 72 are started in this way, in step 24, the processing of opening the cloth belt 18 by the stopping device 80 is performed. That is, by driving the motor 103 of the stopping device 80, the holding table 1
07 and the holding piece 116 are released from the chucking state of the cloth belt 18 to make the cloth belt 18 movable. In this state, in step 25, the motor 62 of the tensioning device 50 is driven to rotate the drive roller 63, and the cloth belt 18 is pulled downward by the pressing force with the pressing rollers 64, 65 and moved downward. The motor 62 of the tension device 50
Simultaneously with the driving of the motor (not shown) of the winding device 30
, The take-up shaft 34 is rotated to take up the fabric belt 18 pulled downward. In the present embodiment, the rotation speed of the pressing roller 35 of the winding device 30 is set to be faster than the rotation speed of the drive roller 63 of the tension device 50. This is to always increase the winding speed on the winding device 30 side so that the cloth belt 18 is not loosened between the winding device 30 and the tension device 50. Therefore, the pressing roller 35 is in a state of slipping little by little with respect to the cloth belt 18. In addition,
The details of the opening process of the stopping device 50 in step 24 will be described later.

As described above, when the driving of the pulling device 50 is started in step 25, the cloth belt 18 is supplied from the storage device 17, so that step 26 is performed.
The position detection sensor 93 provided in the stopping device 80
Is turned on or not. In step 26,
If it is determined that the position detection sensor 93 is in the OFF state, the cloth belt 18 to be newly supplied is in a state in which almost no remaining cloth belt 18 remains. Is in a chucking state, and in step 28, the driving of the tension device 50 is stopped. Thereafter, in step 21, a cloth belt exchange signal is output to the outside to urge the exchange of the cloth belt 18, and in step 22
When the cloth belt 18 is replaced,
It is determined whether or not the position detection sensor 93 is ON. The content of the holding process of the stopping device 50 in step 27 will be described later.

In step 26, the position detection sensor 9
If it is determined that No. 3 is in the ON state, step 2
9, whether the predetermined time has elapsed is measured by the timer (not shown) or the slip detection sensor 7
It is determined whether the number of rotations of the pressure contact roller 65 has reached the predetermined value or not based on 2. Here, if none of the conditions is satisfied, it is determined again in step 26 whether or not the position detection sensor 93 is in the ON state. If any one of the above conditions is satisfied, it is determined in step 30 that the contaminated portion and the unused portion of the cloth belt 18 attached to the guide rail cover 9 have been replaced. The stopping device 80 is driven to bring the cloth belt 18 into a chucking state, and the movement of the cloth belt 18 is stopped. After that, in step 31, it is measured that a predetermined time has elapsed by a timer (not shown), and in step 32, the driving of the tension device 50 is stopped. As described above, after the cloth belt 18 is nipped by the stopping device 80, a predetermined time (for example, 0.
The driving of the tension device 50 is stopped after 5 seconds to 1 second has elapsed since the lower end of the cloth belt 18 is fixed by the stopping device 80 attached to the lower portion of the guide rail cover 9. This is because the upper end of the cloth belt 18 is pulled by the pulling device 50 attached to the upper part of the cloth 9, and the cloth belt 18 can be attached to the guide rail cover 9 in a tensioned state. The content of the holding process of the stopping device 80 in step 30 will be described later.

Next, the contents of the holding process of the cloth belt 18 by the stopping device 80 in the steps 27 and 30 will be described.
This will be described with reference to FIG. As described above, the cloth belt clamping mechanism provided inside the stopping device 80 is the motor 1
A holding piece 116 moved back and forth by a driving force of 03;
It is composed of the holding piece 116 and the holding table 107 to be fitted, and the driving time of the motor 103 is measured by a timer (not shown). Further, inside the stopping device 80, an open state detection sensor 114 for detecting that the holding piece 116 moves backward and the cloth belt 18 is not chucked, and the holding piece 116 moves forward. And a closed state detection sensor 115 that detects that the cloth belt 18 is being chucked.

The stopping device 80 causes the cloth belt 1
When the driving of the motor 103 is started in step 40 in order to pinch 8, immediately after that, the counting of the timer is started in step 41. Then, the holding piece 116 moves forward by the driving of the motor 103, but the holding piece 116
When the cloth belt 18 is clamped by the clamping table 107 to be in a chucking state, the contact piece 113 attached to the upper portion of the clamping piece 116 contacts the closed state detection sensor 115,
The closed state detection sensor 115 is turned on. As described above, in step 42, it is determined whether or not the closed state detection sensor 115 is ON. If it is determined that the closed state detection sensor 115 is ON, the chucking state of the cloth belt 18 is maintained. The operation of the motor 103 is stopped. In step 42, the closed state detection sensor 115
If it is determined that is not ON, step 4
At 3, the driving of the motor 103 is continued until it is determined by the timer that the predetermined time has elapsed. The driving of the motor 103 is continued until the closed state detection sensor 115 is determined to be ON at Step 42 again or until the timer determines that the predetermined time has elapsed at Step 43. If it is determined in step 43 that the predetermined time has elapsed by the timer, an abnormal state in which the clamping process has not been completed even after the appropriate time for completing the clamping process of the cloth belt 18 has elapsed. Therefore, in step 44, an abnormal signal of the stopping device 80 is output, and an abnormal external signal is output to the outside through the abnormality confirmation processing shown in FIG. In response to the stop device abnormality signal, a display lamp (not shown) may be turned on, or a management computer (not shown) may be displayed so as to prompt a store clerk at the game arcade to check and repair the stop device 80. it can. Then, in step 45, the drive of the motor 103 is stopped to prevent a failure.

Similarly, the stopping device 80 in step 24 is used.
FIG. 19 shows the contents of the opening process of the cloth belt 18 by
This will be described with reference to FIG. First, in order to release the chucking state of the cloth belt 18 by the stopping device 80, step 50 is executed.
When the driving of the motor 103 is started, immediately after that, the counting of the timer is started in step 51. Then, the holding piece 116 is moved rearward by the drive of the motor 103, but when a gap is generated between the holding piece 116 and the holding table 107 and the cloth belt 18 is in a non-chucking state, the holding piece 116 is attached to the upper part of the holding piece 116. The contact piece 113 contacts the open state detection sensor 114, and the open state detection sensor 114 is turned on. As described above, in step 52, it is determined whether or not the open state detection sensor 114 is turned on.
If it is determined that the driving is performed, the process proceeds to step 55 to stop the driving of the motor 103 in order to maintain the non-chucking state of the cloth belt 18. Step 5
If it is determined in step 2 that the open state detection sensor 114 is not turned on, the driving of the motor 103 is continued until it is determined in step 53 that the predetermined time has elapsed by the timer. The driving of the motor 103 is continued until it is determined in step 52 that the open state detection sensor 114 is ON, or it is determined in step 53 that the predetermined time has elapsed by the timer. If it is determined in step 53 that the predetermined time has elapsed by the timer, an abnormal state in which the opening process has not been completed even after the appropriate time for completing the opening process of the cloth belt 18 has elapsed. Therefore, at step 54, an abnormal signal of the stopping device 80 is output, and
An abnormal external signal is output to the outside through the abnormal confirmation processing shown in FIG. Therefore, it is possible to externally confirm that an abnormality has occurred in the stop device 80. Thereafter, in step 55, the drive of the motor 103 is stopped to prevent a failure.

As described above, in the automatic winding control of the cloth belt 18 by the ball polishing cloth belt automatic winding mechanism, the abnormality confirmation processing for each part constituting the ball polishing cloth belt automatic winding mechanism is performed. The contents of the abnormality confirmation processing will be described with reference to FIG. First,
In the stop device 80, an abnormality may occur in which the cloth belt 18 is not completed, even though an appropriate time to complete the processing for clamping or releasing the cloth belt 18 by the cloth belt clamping mechanism has elapsed. Therefore, step 60
It is determined whether or not such an abnormality has occurred. If it is determined in step 60 that an abnormality has occurred in the stop device 80, an abnormality signal is output to a display lamp or a management computer (not shown) provided in the pachinko island stand in step 63. A clerk at the amusement arcade can be urged to inspect and repair the stop device 80.

If it is determined in step 60 that an abnormality has not occurred in the stopping device 80, it is determined in step 61 whether or not an abnormality has occurred in the pulling device 50. That is, the tensioning device 50 includes the driving roller 63 driven by the motor 62 and the pressing roller 6.
The cloth belt 18 is pulled by the pressure contact force with the cloth belts 4, 65. However, an abnormality may occur in which the cloth belt 18 is not normally pulled due to a slip or the like. Therefore, if it is determined in step 61 that the rotational speed of the pressure contact roller 65 detected by the slip detection sensor 72 does not exceed the predetermined value, an abnormal signal is output to a management computer (not shown) in step 63. Therefore, the clerk of the game hall can be urged to inspect and repair the tension device 50. If it is determined in step 61 that the number of rotations of the pressing roller 65 has exceeded the predetermined value, the process proceeds to step 6.
At 2, it is determined whether or not the tension device 50 is stopped. That is, if the driving of the tension device 62 is not stopped after the automatic winding process of the cloth belt 18 is completed, step 63
Then, an abnormal signal is output to the management computer (not shown), so that the clerk at the game hall can be urged to inspect and repair the tension device 50. As described above, the tension of the cloth belt 18 attached to the guide rail cover 9 is always kept constant by the tension device 50. An example of control for this is shown in FIG. It will be described with reference to FIG. FIG. 21 is a flowchart illustrating an example of drive control of the tension device 50.

As described above, the pulling device 50 is attached to the guide rail cover 9 so as to be slidable up and down by the length of the locking groove 56a. Further, the tension device 50 is provided with a looseness detection sensor 59, and by detecting the looseness of the cloth belt 18 and controlling the driving of the motor 62, the tension of the cloth belt 18 can be kept constant. When the cloth belt 18 gradually expands with the elapse of the driving time of the doffing and conveying device 1, as shown in FIG.
When the tension device 50 reaches the lower limit position, the looseness detection sensor 59 is turned on from OFF.
Switch to. However, repeating the ON / OFF a predetermined number of times (for example, three times) within a range of a predetermined time (for example, one hour) by the looseness detection sensor 59 is, for example,
The stopping device 80 or the pulling device 50 is firmly
Since it is conceivable that the motor 8 is not pinched and slips little by little, it is controlled in this embodiment to output an abnormal signal in consideration of such a situation.

Therefore, first, at step 70, the value of the abnormal processing number counter N is reset to "0". Next, at step 71, a timer for measuring a predetermined time (for example, one hour) is started. It is determined whether or not the looseness detection sensor 59 is ON. And
When it is determined that the looseness detection sensor 59 has been turned on within the above-described predetermined time, a looseness correction processing subroutine is executed in step 73. This looseness correction subroutine is shown in FIG. 22 and will be described.

In step 80, the motor 6 of the tensioning device 50
In step 81, a timer for measuring a relatively short time (for example, 4 seconds) starts. This timer is activated when the looseness detection sensor 59 is turned ON from ON.
A sufficient time for switching to FF is set. Thus, when the motor 62 starts driving, the cloth belt 18 is wound up by the driving roller 63, and the tension device 50 starts to rise. If the tension device 50 continues to rise, the looseness detection sensor 59 is turned off, but the motor 62 of the tension device 50 is turned off.
Is driven until the predetermined time elapses even after the looseness detection sensor 59 is turned off. Therefore, step 8
0, after the motor 62 is started to drive,
It is determined whether or not the looseness detection sensor 59 has been turned off. At step 82, the looseness detection sensor 59 is turned off.
If it is determined that the time has become, the timer is started in step 83. While the timer is operating, the motor 62 continues to be driven.
If it is determined in step 4 that the predetermined time set by the timer has elapsed, in step 85, the driving of the motor 62 is stopped, and the process returns to the main routine. Step 83 like this
The reason for performing the processing of steps 85 to 85 is that, as in the conventional case, each time the looseness detection sensor 59 switches from ON to OFF, the motor 62
If the driving of the motor 62 is stopped, the motor 62 is frequently driven or stopped, so that the efficiency is low and the life of the motor 62 is adversely affected.

On the other hand, if it is determined in step 82 that the looseness detection sensor 59 is not OFF, and if it is determined in step 86 that the timer started in step 81 has timed out, that is, it is sufficient time to eliminate the looseness. If it is determined that the slack is not resolved even after the elapse,
This looseness correction processing subroutine ends, and the process returns to the main routine. In addition, the fact that the slack is not eliminated even after a sufficient time has passed for eliminating the slack indicates that the pulling device 50 or the stopping device 80 has failed.

After returning to the main routine and executing the above-described looseness correction processing subroutine, "1" is added to the abnormal processing number counter N in step 74, and then, in step 75, the value of N is set to a predetermined number of times. It is determined whether it is larger than (two times). If it is smaller than the specified number, the process proceeds to step 76 to determine whether or not the timer set in step 71 has elapsed. If not, the process returns to step 72 and repeats steps 72 to 76.

If the execution of the slack correction processing is not more than the specified number of times at the time when the timer set in step 71 elapses, YES is determined in step 76 and the main routine is terminated. The processing from step 70 is repeated again. On the other hand, if the execution of the slackness correction processing is three or more times greater than the specified number of times before the timer set in step 71 elapses, it is determined as YES in step 75 and the tension device abnormality signal is output to the management computer or It is led to a display lamp provided on the pachinko island stand to indicate that fact. If the execution of the slackness correction processing is three or more times, which is more than the specified number of times, before the timer set in step 71 elapses, as described above, the stopping device 80 or the pulling device 50 firmly holds the cloth belt 18. This is because it is conceivable that they are not pinched and slip slightly. In addition, the stopping device 80 or the pulling device 50
Is completely broken and the cloth belt 18 is not pinched, the abnormal processing number counter N becomes 3 or more in a very short time. Therefore, such a failure of the stop device 80 or the tension device 50 is also performed by the above-described control. You can easily find out.

While the construction and operation of the ball polishing cloth belt automatic winding mechanism according to the embodiment have been described above, according to this embodiment, as shown in FIGS. The ball polishing cloth belt automatic winding mechanism used in the ball lifting device 1 used in the ball lifting device 1 that holds and lifts the pachinko ball while polishing the pachinko ball by facing the ball polishing cloth 11 with the ball polishing cloth belt 18.
