Therefore, first, the structure of the winding mechanism portion 10 will be described with reference to FIGS. 2 is a side view showing the relationship between the winding mechanism unit 10 and the mounting mechanism unit 50, FIG. 3 is a perspective view of the winding mechanism unit 10, and FIG.
FIG. 5 is an enlarged side view of the winding mechanism section 10, FIG. 5 is a perspective view showing a state in which the lid section 71 is opened from the support base main body section 70 in the pulling drive section 11 of the winding mechanism section 10, and FIG. ,
FIG. 5 is a cross-sectional view taken along the line AA of the tension driving unit 11 in FIG. 4. In the figure, the winding mechanism section 10 is composed of the pulling drive section 11 and the winding section 12 as described above. First, the structure of the pulling drive unit 11 will be described with reference to FIGS. 3 to 5. The pulling drive unit 11 is a slide support that holds the cover plate 8 on the back surface of the cover plate 8 and is slidably attached. They are collectively provided on the table 13. That is, as shown in FIG. 4, the slide support base 13 has bolts projecting from the side surface of the cover plate 8 penetrate through the elongated slide holes 14 formed at the upper and lower ends of the rear end of the sliding support base 13 and fixed to the bolts. By fixing the nut 15, it is slidable up and down within the range of the sliding elongated hole 14.

The sliding support base 13 has a support base body portion 70.
The lid portion 71 is formed by a cover 71 and a lid portion 71. The lid portion 71 can be opened with respect to the support base body portion 70 when the cloth belt 80 is attached or detached. The same applies to the left and right definitions below) hinge 72
The hinge is rotatably attached to the support base body 70. At all times (when the ball polishing and lifting device 1 is driven) the support base body 70 and the lid 7
1 is kept closed by a fastening device 73 provided on the opposite side (right side) from the hinge 72. The fastening device 73 includes a fastening lever 76 with a fastening fitting 75 rotatably mounted on a substrate 74 provided on the support base body 70,
The support base is composed of a locking piece 77 protruding from the lid 71, and the locking metal fitting 75 is engaged with the locking piece 77 and the locking lever 76 is pressed toward the supporting base body 70. The main body 70 and the lid 71 are kept closed. The support base main body 70 is provided with a notch 25 on the front side of its upper part, while its lower part is formed in a hollow shape. This serves as a path for the cloth belt 80 when the lid 71 is closed. Further, on one inner side of the lid 71,
As shown in FIGS. 5 and 6, a side wall 84 for forming the space 83 is provided. This is because the drive gear 99, which will be described later, and the upper / lower pressure contact rollers 21a, when the lid 71 is closed
It is for avoiding contact with 21b.

A drive unit storage box 16 is fixed to the lower outside of the right side portion of the support base body 70, and a tension motor 17 is fixed inside the drive unit storage box 16 to support the support main body 70. As shown in FIG. 6, a bearing 78, which will be described later, is fixed to the motor shaft 19 of the tension motor 17, and a motor gear 79 is fixed to the outer side of the bearing 78 at the inner lower portion of the right side of the. On the other hand, a manual winding device 90, which will be described later, is provided on the lower outside of the left side portion of the support base body 70.

The drive roller 20 is provided inside the support base body 70, and the drive roller 20 is provided inside the lid 71.
Two upper and lower pressure contact rollers 21a and 21b, which are pressed against each other, are rotatably provided, of which the drive shaft of the drive roller 20 has a drive gear 99 meshing with the motor gear 79.
Is stuck. Therefore, when the tension motor 17 is driven while the support base body 70 and the lid 71 are held in the closed state, the motor gear 79 fixed to the motor shaft 19 rotates, and the motor gear 79 is rotated. Since the drive gear 99 rotates in conjunction with, the drive roller 20 rotates, and the upper and lower pressure contact rollers 21a and 21b pressed against it also rotate in the opposite direction to the drive roller 20. Then, the drive roller 20
The cloth belt 80 is fitted between the upper and lower pressing rollers 21a and 21b, but the cloth belt 80 is pulled by the rotation of the drive roller 20.

Next, the manual winding device 90 will be described in detail with reference to FIGS. 3 and 6. The manual winding device 90 is composed of a winding portion and a regulating portion. First, the winding portion 1 extends until the winding portion projects to the left side wall of the support base body 70.
The ratchet gear 91 is fixed to the motor shaft 19 of No. 7 with an appropriate clearance from the outside of the left side wall.
The winding lever 92 is fitted and formed from the outer side of 1, and when the winding lever 92 rotates, the ratchet gear 91 also rotates together. The take-up lever 92 is a hole 96 formed in a prismatic shape (hexagonal shape in the figure) to be fitted into the tip end portion 97 of the motor shaft 19, and is detachably fitted to the motor shaft 19. Therefore, as described above. When the pulling motor 17 is driven to wind up the cloth belt 80, if it is removed, it does not rotate together with the pulling motor 17. Further, the play space is an interval required to avoid contact between the left side surface of the lid 71 and the manual winding device 90 when the lid 71 is released from the support base body 70.

The restricting portion includes a rotation restricting lever 94 rotatably supported by a support shaft 93 projecting from the left side wall of the lid 71, substantially below the ratchet gear 91, and the rotation restricting lever 94. It is formed of a central portion and a spring 95 which is stretched between a support shaft 93 and a stop shaft 98 provided on the support base main body 70 in the same manner as the support shaft 93. This spring 95
The rotation restricting lever 94 is urged in a direction to engage the ratchet gear 91. That is, the tip of the rotation restricting lever 94 is always engaged with the ratchet gear 91, and because of the relationship between the downward tooth shape of the ratchet gear 91 and the upward tooth shape of the tip of the rotation restricting lever 94, the take-up lever 92 is Although it is possible to rotate 80 in the winding direction (the same rotation direction as tension motor 17), it is no longer possible to rotate cloth belt 80 in the loosening direction. Therefore, when the support base body 70 and the lid 71 are held in the closed state, when the winding lever 92 is rotated, the drive roller 20 is rotated in the same manner as described above, and the upper and lower pressure contact rollers are pressed against it. 21a and 21b also rotate in the opposite direction to the drive roller 20, and the drive roller 20 and the upper / lower pressure contact roller 21
The cloth belt 80 fitted between a and 21b is pulled.

The take-up lever 92 directly attached to the motor shaft 19 of the tension motor 17 has the bearing 78 described above.
By the action of, the motor shaft 19 can be rotated while the tension motor 17 is not driven. That is, the bearing 78 allows the take-up lever 92 to rotate if the direction of rotation of the take-up lever 92 is the same as the direction of rotation of the motor shaft 19 of the tension motor 17, and takes the take-up lever 92 in the opposite direction. The rotation of the lever 92 is rejected. Therefore, the ratchet gear 91 and the rotation restricting lever 94 have the same function as that described above, and a strong force is exerted to prevent the drive roller 20 from rotating in the direction in which the cloth belt 80 is loosened.

As is apparent from the above-mentioned configuration, the manual winding device 90 is formed on the side surface of the ball-pulling and lifting device 1, so that, for example, when the pulling motor 17 malfunctions or other equipment troubles occur. If the automatic winding of the belt 80 is hindered, the door for the ball polishing and lifting device 1 on the pachinko island stand is opened from the passage side of the hall and the cloth belt 80 can be easily pulled by turning the winding lever 92. Can be rolled up.

By the way, when the cloth belt 80 is inserted between the driving roller 20 and the upper and lower pressure contact rollers 21a and 21b, the fixing device 73 is operated and supported as shown in FIG. This is performed after the lid 71 is opened from the table body 70. That is, the fastening lever 76 is rotated in the direction in which the lid portion 71 is opened to engage and disengage the metal fitting 75 and the locking piece 77, the lid portion 71 is opened, and the drive roller 20 is moved to the upper and lower pressure contact rollers 21a and 21b. The pressed state is released, the cloth belt 80 is hung down, and the lid 71 is held in the closed state again by the fastening lever 76 on the support base body 70. Then, by winding the front end of the cloth belt 80 around the winding unit 12 which will be described later, the cloth belt 80 moves the driving roller 20 as shown in FIG.
And the upper and lower pressure contact rollers 21a and 21b. As described above, in the present invention, the cloth belt 8 can be operated by one-touch operation of only operating the fastening device 73 to control the opening / closing of the lid 71.
Since 0 can be attached to the pulling drive unit 11, replacement work of the cloth belt 80 becomes easy.

For example, it may be provided in the winding unit 12. In this case, a manual take-up device 90 is formed at one end of the take-up shaft 33 in the same manner as described above, the lid 71 is opened from the support base body 70, and the drive roller 20 and the upper / lower press-contact rollers 21a, 21b. After releasing the pressure contact state, the winding lever 92 is rotated to rotate the winding shaft 33 and wind the cloth belt 80. In this way, the manual winding device 90 may be provided at an appropriate position on the side surface portion of the ball polishing and lifting device 1.

Next, referring to FIGS. 2, 7 and 8,
The configuration of the mounting mechanism unit 50 will be described. FIG. 7 is a perspective view of the mounting mechanism section 50, and FIG. 8 is an enlarged side view of the mounting mechanism section 50. In the figure, the mounting mechanism section 50 includes the cloth belt mounting section 51 for mounting the cloth belt 80 before use and the delivery section 52 for sending out the mounted cloth belt 80 as described above. Therefore, first, the structure of the cloth belt mounting portion 51 will be described with reference to FIGS. 7 and 8. The cloth belt mounting portion 51 has a substantially triangular plate shape that is screwed to both sides of the cover plate 8 with nuts 54. Mounting support 53
It is provided in a consolidated manner. That is, fitting grooves 55a and 55b (however, 55a is not shown) are formed at the tip of the mounting support base 53, and the cloth belt 80 before use is wound around the fitting grooves 55a and 55b in a roll shape. The winding shaft 56 of the front cloth belt roll 80a is hooked.

A pressing lever frame 58 having a pressing roller 57 at the tip thereof is swingably supported on a rotary shaft 59 which is provided above the rear end of the mounting support base 53. Since the presser lever frame 58 extends slightly ahead of the position where the fitting grooves 55a and 55b are formed,
As shown in FIG. 8, the pressing roller 57, which is rotatably supported by the tip of the pressing lever frame 58, is located diagonally forward of the wound pre-use cloth belt roll 80a. Further, between the front end side of the presser lever frame 58 and the mounting support base 53, the presser roller 57 is always provided with the pre-use cloth belt roll 8
A spring 60 that urges the 0a in a direction to press it is bridged. As a result, before use the cloth belt roller 80a
Is prevented from being naturally loosened, and the cloth belt 80 is smoothly fed while being stretched neatly.

On the other hand, the delivery portion 52 is provided integrally on a support base 61 having a substantially square plate shape, which is screwed to both sides of the cover plate 8 with nuts 62. That is, the support base 61 has 1
Two large-diameter pressure contact rollers 63, and a small-diameter pressure contact roller 64 arranged so as to be in pressure contact with the pressure contact roller 63 diagonally above and below,
65 has been handed over. And the cloth belt 80 is
It is inserted between the large-diameter pressure contact roller 63 and the small-diameter pressure contact rollers 64 and 65 and pulled out downward. A ratchet gear 66 is fixed to the rotation shaft of the large-diameter pressure contact roller 63 outside the support base 61, and a stopper lever 67 is provided above the ratchet gear 66.
One end of the stopper lever 67 is rotatably supported by the support base 61 by a support shaft 68, and one end of a connecting rod 85 is locked to the other end. Further, in the middle lower part of the stopper lever 67, the ratchet gear 6 is provided.
Engaging claws 69 that engage with the six teeth are formed. The other end of the connecting rod 85 is connected to the slide support base 13 of the pulling drive unit 11 of the winding mechanism unit 10 as described above.

Next, the winding mechanism section 1 having the above-mentioned structure.
0 and the mounting mechanism section 50 will be described for attaching the cloth belt 80 to the ball-polishing and lifting device 1. The take-up shaft 56 of the new pre-use cloth belt roll 80a is attached to the cloth belt mounting section 5.
After being fitted into the first fitting grooves 55a and 55b, the cloth belt 80
The tip of the stopper lever 6 is inserted between the large-diameter pressure contact roller 63 and the small-diameter pressure contact rollers 64 and 65 of the delivery section 52.
With the engagement of 7 disengaged, the large diameter press roller 63 is manually rotated to pull out the cloth belt 80 of a required length downward. After that, the cloth belt 80 is passed from the lower part to the upper part on the front surface of the cover plate 8 in the opened state, and as described above, the driving roller 20 of the tension driving unit 11 and the upper / lower pressure contact roller 21 are connected.
The cloth belt 80 is fitted between a and 21b. Further, the excessively pulled out cloth belt 80 is wound around the winding shaft 33, and in that state, the winding cam 37 of the pressing lever frame 34 is brought into contact with the outer periphery of the used cloth belt roll 80b. After the wearing of the cloth belt 80 is completed as described above, the cover plate 8 is closed and the fastening lever 9 is engaged so that the cloth belt 80 and the conveyor belt 5 face each other.

Next, the related operation between the winding mechanism section 10 and the mounting mechanism section 50 will be described. The cloth belt 80 is always forcibly pushed up by frictional force while the pachinko balls are being conveyed by the conveyor belt 5 (while the ball polishing and lifting device 1 is being driven). Therefore, the cloth belt 80 is in a loosened state in the portion of the pulling drive unit 11, and the slide support base 13 is in a lowered position. When the slide support base 13 is in the lowered position, the connecting rod 85 is also lowered and the engaging claw 69 of the stopper lever 67 is moved to the ratchet gear 66.
Engage with. For this reason, the rotation of the large diameter press roller 63 is stopped, so that the supply of the cloth belt 80 by the large diameter press roller 63 and the small diameter press rollers 64, 65 is also stopped. In such a state, the cloth belt 80 is not pushed up by the frictional force of the conveyor belt 5, and the cloth belt 8
Zero will not loosen further.

Next, when winding the cloth belt 80, the ball polishing and lifting device 1 is stopped, and the tension motor 17 and the winding motor 41 of the winding mechanism portion 10 are rotationally driven. Therefore, the cloth belt 80 is always wound, but since the tension motor 17 is driven, the tension drive unit 1
In 1, the cloth belt 80 is retracted. Then, when the pull-in is continued, the slide support base 13 starts to move up, and finally rises to a position where the engagement between the engaging claw 69 of the stopper lever 67 and the ratchet gear 66 is released. When the engagement between the engaging claw 69 and the ratchet gear 66 is released, the large diameter press contact roller 63 and the small diameter press contact rollers 64, 6 are released.
5, the feeding of the cloth belt 80 is started, the cloth belt 80 is wound by a predetermined length (the length of the cover plate 8), and then the tension motor 17 and the winding motor 41 are stopped. It should be noted that the tension motor 17 and the winding motor 41 have the same rotation speed, or the rotation speed of the winding motor 41 is the same.
It may be slightly slower than the rotation speed.

As is clear from the above description, in this embodiment, the movement control of the cloth belt 80 is controlled by the pulling drive section 11 and the delivery section 52. That is, the cloth belt 80 is locked and its supply is stopped while the ball polishing and lifting device 1 is driven, and the lock is released so that the cloth belt 80 can be moved while the ball polishing and lifting device 1 is stopped. It is controlled. The moving speed of the cloth belt 80 is
Since the hole is substantially determined by the capacity of the pulling motor 17, it is sufficient to select the pulling motor 17 corresponding to the desired winding speed for the hole. For example, the rotation speed of the tension motor is 30r
pm and the diameter of the motor shaft 19 is 20 mm, the length of the cloth belt 80 that moves in 1 minute is 20 × π × 30≈1884 mm.

The operation control of the automatic winding of the cloth belt 80 is executed according to the flow charts shown in FIGS. FIG. 9 is a main process (main routine) of the winding operation of the cloth belt 80 according to the present invention.
11 is a stopping process of the ball polishing and lifting device 1, and FIG. 11 is a process of moving the cloth belt 80. First, in FIG. 9, it is determined in step (hereinafter abbreviated as S) 100 whether or not the business is completed. If the business is in business, the operation of returning to S100 is repeated, and if completed, the process proceeds to S120. S
Reference numeral 120 is a subroutine that defines the stopping process of the ball polishing and lifting device 1. As shown in FIG. 10, first, in S121, the pachinko balls that flow down to the introduction gutter 6 of the ball polishing and lifting device 1 are stopped. This stopping method is performed by, for example, providing an opening / closing plate that is operated by a motor or the like on the side wall of the ball storage tank (not shown) to control the opening / closing of the ball outlet.

Next, the process proceeds to S122 and the ball polishing and lifting device 1
Whether there are any pachinko balls remaining inside, that is, all the pachinko balls that have entered the ball polishing and lifting device 1 are in the ball discharge port 7 (Fig. 1).
If there is still a pachinko ball in the ball polishing and lifting device 1, the operation of returning to S122 is repeated, and if all the pachinko balls have flowed out, S12 is determined.
3, the power of the ball-polishing and lifting device 1 is turned off, the ball-polishing and lifting device 1 is stopped, and the process returns to the main routine. Then, the flow shifts to S140, where it is determined whether the dirt sensor 88 for checking the dirt of the cloth belt 80 is ON.

As shown by the broken line in FIG. 1, the dirt sensor 88 is provided on both side walls of the upper cover 7 of the ball-pulling and lifting device 1 and reflects light composed of a light emitting portion 89a and a light receiving portion 89b. Is an optical sensor that utilizes. The light emitted from the light emitting portion 89a is incident on the ball-polished surface of the cloth belt 80 at, for example, an entrance angle θ, is reflected by the cloth belt 80, and is received by the light receiving portion 89a.
b is reached. In this case, since the angle of the reflected light is the same as the approach angle θ, the light emitting section 89a and the light receiving section 89b may be installed at positions satisfying the condition.
Then, while the ball-polished surface of the cloth belt 80 is clean,
The cloth belt 80 is also white in color, the amount of light reaching the light receiving portion 89b is large, and the stain sensor 88 is off. When the cloth-polished surface of the cloth belt 80 becomes extremely dirty, the color of the cloth belt 80 becomes dark, and therefore the cloth belt 8
The light emitted from the light emitting portion 89a to 0 is absorbed to some extent and the amount of light reaching the light receiving portion 89b is reduced, and when it becomes less than the set value, the dirt sensor 88 is turned on. Then, if it is determined in S140 that the dirt sensor 88 is OFF, the main routine ends, and if it is determined to be ON, the process proceeds to S150.

S150 is a subroutine for defining the movement processing of the cloth belt 80, and as shown in FIG. 11, first, the movement count is incremented by 1 in S151. Therefore, this movement count is incremented by 1 every time the cloth belt 80 moves. Next, in S152, it is determined whether the replacement count and the movement count count are the same.

Here, the number of times of replacement is a value indicating how many times the cloth belt 80 can be moved by one winding, and requires an initial setting. For example, the height of the cover plate 8 of the ball polishing and lifting device 1 is 2
Assuming that the length of the cloth belt 80 is 400 mm and the length of the cloth belt 80 is 25000 mm, the length for moving the dirty cloth belt 80 once is almost equal to the height of the cover plate 8, so 25000 ÷ 2400≈10.4167, which is below the decimal point of the above solution. The positive part obtained by rounding down is the initial setting value, which is 10 in this case.

When the number of times of replacement and the number of times of movement are equal, the process proceeds to S153 and the cloth belt 80 is moved.
After displaying the replacement warning light (not shown), S155
Move to. This cloth belt 80 replacement warning light is placed in a place that can be easily seen by a clerk, such as the end of a pachinko island stand, and is lit or blinked, or a computer in the hall management room is equipped with a pilot lamp, LED, or the like to illuminate and display. And good.

On the other hand, when the number of times of replacement and the number of times of movement counting are not equal in S152, the process proceeds to S154, and the magnitude of the number of times of replacement and the number of movement counting is determined. If the replacement count is greater than the movement count count, S
After shifting to 155 to move the cloth belt 80 by a predetermined section, the process returns to the main routine, and the main routine ends. If the replacement count is smaller than the movement count count in S154, the process proceeds to S156 and the cloth belt 80
A replacement lamp (not shown) is displayed. This cloth belt 8
The 0 replacement light is formed in accordance with the cloth belt 80 replacement notification light described above. Then, in S157, the cloth belt 80 is replaced, and in S158, the movement count is set to 0, and then the process returns to the main routine.
The main routine ends as it is.

As described above, the cloth belt 80 has the dirt sensor 88 when the pachinko hall is closed for one day.
The dirt state is determined by, and when the dirt is severe, the dirt sensor 88 is turned on, and the cloth belt 80 is automatically wound up for a predetermined section (the height of the cover plate 8) to prepare for the opening of the next day. Moreover, when the cloth belt 80 approaches the end, the cloth belt 80 replacement notice lamp or the replacement lamp lights up, so that it is possible to easily grasp the time when the cloth belt 80 is replaced with a new cloth belt 80. Also, the above S
As means for winding the cloth belt 80 of 155 in a predetermined section,
Based on the height of the cover plate 8 and the winding speed of the tension motor 17, the time required for winding the section is calculated in advance, and the tension motor 17 is driven for that time, or based on the detection signal of the dirt sensor 88. A method of controlling the pulling motor 17 by means of the like is preferable. If S155 is not executed even when the dirt sensor 88 is ON, that is, if the cloth belt 80 cannot be automatically wound for some reason, or if the cloth belt 80 is forcibly wound, the dirt sensor The winding lever of the manual winding device 90 may be rotated until 88 is turned off.

Next, another embodiment of the operation control of the automatic winding of the cloth belt 80 will be described with reference to FIGS. First, FIG. 12 is a main process (main routine) showing another embodiment of the winding operation of the cloth belt 80. In the figure, it is determined in S200 whether the dirt sensor 88 is ON, and if OFF, the process returns to S200. The returning operation is repeated, and if ON, the process proceeds to S220. And S2
At 20, the stopping process of the ball-polishing and lifting device 1 shown in FIG. 10 is performed, and the process proceeds to S240. At S240, the movement process of the cloth belt 80 shown in FIG. 11 is performed and S26.
Move to 0. Then, in S260, it is determined whether or not it is in business. If it is not in business, the main routine ends as it is, and if it is in business, the process proceeds to S280. S280 is
This is a subroutine that defines the start-up process of the ball-polishing and lifting device 1, and as shown in FIG. 13, first, in step S281, the power of the ball-polishing and lifting device 1 is turned on and then the process proceeds to step S282. After waiting for a fixed time until the speed is reached, the process proceeds to S283. Then, in S283, the opening / closing plate of the above-mentioned ball storage tank is opened in the introduction gutter 6 of the ball polishing and lifting device 1 to allow the pachinko balls to flow down, and then the process returns to the main routine and shifts to S200 again.
