  Embodiments of the present invention will be described below with reference to the drawings. First, with reference to FIG. 1, the whole structure of the ball polishing lifting apparatus 1 which concerns on an Example is demonstrated. FIG. 1 is a perspective view of the ball polishing and lifting device 1. In the figure, the ball polishing and lifting device 1 is driven by a motor built-in pulley 4 in which a lifting cylinder body 3 is erected vertically on an upper part of a support base 2 and the inside of the lifting cylinder body 3 is supported by a lower part. The conveyor belt 5 is configured to circulate. An introduction rod 6 into which a pachinko ball before polishing from a ball storage tank (not shown) flows is formed at the lower part of the lifting cylinder body 3. An upper cover 7 from which pachinko balls are discharged is formed. Therefore, the pachinko balls that have flowed in from the introduction cage 6 are lifted by the conveyor belt 5 and discharged from the upper cover 7, but adhere to the pachinko balls by the frictional force with the cloth belt 80 described later in the process of being lifted. The cleaned dirt is wiped off, and the cleaned pachinko balls are discharged from the upper cover 7. A dirt sensor 88 described later is attached to the inside of the side wall of the upper cover 7.

  On the other hand, a cover plate 8 is pivotally supported on one side and attached to the back side of the above-described lifting cylinder body 3 so as to be freely opened and closed. The cover plate 8 is opened when the transport belt 5 or the cloth belt 80 is mounted on the ball polishing and lifting device 1, and the cloth belt 80 itself circulates the cover plate 8 in the vertical direction. It is attached to. When the transport belt 5 and the fabric belt 80 are attached, the cover plate 8 is maintained in a state of facing the lifting cylinder body 3 by the fixing lever 9. The ball polishing and lifting device 1 configured as described above is installed with the side surface facing the passage side with respect to the pachinko island platform.

  By the way, on the back surface of the cover plate 8, the winding mechanism unit 10 and the mounting mechanism unit 50 constituting the main part of the present embodiment are attached. The winding mechanism unit 10 winds up the used cloth belt 80 by the driving force of the motors 17 and 41, and includes a tension driving unit 11 and a winding unit 12. The mounting mechanism unit 50 is used to mount the fabric belt 80 before use, and includes a fabric belt mounting unit 51 and a sending unit 52.

  First, the configuration of the winding mechanism unit 10 will be described with reference to FIGS. 2 is a side view showing a 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. 4 is an enlarged view of the winding mechanism unit 10. 5 is a side view, FIG. 5 is a perspective view showing a state in which the lid 71 is opened from the support base body 70 in the tension driving unit 11 of the winding mechanism unit 10, and FIG. 6 is a tension driving unit in FIG. 11 is a cross-sectional view taken along line AA of FIG. In the figure, the winding mechanism unit 10 is composed of the tension driving unit 11 and the winding unit 12 as described above. First, the configuration of the tension drive unit 11 will be described with reference to FIGS. 3 to 5. The tension drive unit 11 is a sliding support that sandwiches the cover plate 8 on the back surface of the cover plate 8 and is slidably attached. The table 13 is provided in a consolidated manner. That is, as shown in FIG. 4, the sliding support base 13 allows a bolt projecting from the side surface of the cover plate 8 to pass through a sliding long hole 14 formed at the upper and lower ends of the rear end portion, and is fixed to the bolt. By fixing the nut 15, it can slide up and down within the range of the sliding long hole 14.

  The sliding support base 13 is formed of a support base main body 70 and a lid 71, and the lid 71 is located on the left side (here, so that it can be opened to the support base main body 70 when the cloth belt 80 is attached or detached). 2 is hinged to the support base body 70 by a hinge 72 so as to be rotatable when viewed from the direction of arrow B in FIG. The support base body 70 and the lid 71 are always kept closed by a fastening device 73 provided on the opposite side (right side) of the hinge 72 (when driving the ball polishing and lifting device 1). The fastening device 73 includes a fastening lever 76 with a fastening member 75 that is rotatably attached to a substrate 74 provided on the support base body 70, and a locking piece 77 that projects from the lid 71. The stopper plate 75 is engaged with the locking piece 77 and the fixing lever 76 is pressed in the direction of the support base body 70 to maintain the closed state of the support base main body 70 and the lid 71. It is like that. The support base body 70 is provided with a notch 25 on the upper front side thereof, while its lower part is formed in a hollow shape. This is a path of the cloth belt 80 when the lid 71 is in the closed state. Further, as shown in FIGS. 5 and 6, a side wall 84 for forming the space portion 83 is provided on the inner side of the lid portion 71. This is for avoiding contact between a drive gear 99 (described later) and the upper and lower pressure contact rollers 21a and 21b when the lid 71 is closed.

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

  In addition, a driving roller 20 is inserted inside the support base body 70, and two upper and lower pressing rollers 21a and 21b pressed against the driving roller 20 are rotatably inserted inside the lid 71. A drive gear 99 that meshes with the motor gear 79 is fixed to the rotating shaft of the drive roller 20. Accordingly, when the tension motor 17 is driven when 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 rotation, the drive roller 20 rotates, and the upper and lower pressure contact rollers 21a and 21b pressed against the drive roller 20 also rotate in the opposite direction to the drive roller 20. Thus, the cloth belt 80 is inserted between the driving roller 20 and the upper and lower pressure contact rollers 21 a and 21 b, but the cloth belt 80 is pulled by the rotation of the driving 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 includes a winding unit and a regulating unit. First, the winding unit is placed on the motor shaft 19 of the tension motor 17 that is extended until it protrudes from the left side wall of the support base body unit 70. The ratchet gear 91 is fixedly secured from the outside of the side wall with an appropriate clearance, and the winding lever 92 is fitted from the outside of the ratchet gear 91. When the winding lever 92 rotates, the ratchet gear 91 also rotates together. It is supposed to be. The take-up lever 92 is a hole 96 that fits into the front end portion 97 of the motor shaft 19 formed in a prismatic shape (hexagonal shape in the drawing), and is detachably fitted to the motor shaft 19. In the case of winding the fabric belt 80 by driving the tension motor 17, if it is removed, it does not rotate together with the tension motor 17. Further, the clearance is an interval necessary 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 on a support shaft 93 protruding from the left side wall of the lid portion 71 at a substantially lower portion of the ratchet gear 91, and a substantially central portion of the rotation restricting lever 94. In the same manner as the support shaft 93, a spring 95 is formed between the support shaft main body 70 and a stop shaft 98 provided on the support base body portion 70. The spring 95 biases the rotation restricting lever 94 in a direction to engage the ratchet gear 91. In other words, the leading end of the rotation restricting lever 94 is always engaged with the ratchet gear 91, and the take-up lever 92 is a cloth belt because of the relationship between the downward tooth shape of the ratchet gear 91 and the upward tooth shape of the leading end of the rotation restricting lever 94. Although it is possible to rotate 80 in the winding direction (the same rotation direction as that of the tension motor 17), the cloth belt 80 cannot be rotated in the loosening direction. Accordingly, when the support base body 70 and the lid 71 are held in the closed state, when the take-up lever 92 is rotated, the driving roller 20 is rotated in the same manner as described above, and the upper and lower pressure contact rollers are pressed against the roller. 21a and 21b also rotate in the opposite direction to the drive roller 20, and the cloth belt 80 fitted between the drive roller 20 and the upper and lower pressure contact rollers 21a and 21b is pulled.

  The take-up lever 92 directly attached to the motor shaft 19 of the tension motor 17 can rotate the motor shaft 19 in a state where the tension motor 17 is not driven by the action of the bearing 78 described above. In other words, the bearing 78 described above allows the winding lever 92 to rotate if the rotation direction of the winding lever 92 is the same as the rotation direction of the motor shaft 19 of the tension motor 17, and winds the winding lever 92 if it is the opposite direction. The rotation of the lever 92 is rejected. Therefore, the operation is the same as the action of the ratchet gear 91 and the rotation restricting lever 94 described above, and the action of the both makes a strong force for preventing the rotation of the driving roller 20 in the direction in which the cloth belt 80 is loosened.

  As apparent from the above-described configuration, the manual winding device 90 is formed on the side surface portion of the ball polishing and lifting device 1, so that the cloth belt 80 may be damaged due to, for example, a failure of the tension motor 17 or a trouble with other equipment. If the automatic winding is hindered, the cloth belt 80 can be easily wound simply by opening the door for the ball polishing and lifting device 1 on the pachinko island stand from the hall passage side and turning the winding lever 92. Can do.

  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, as shown in FIG. The operation is performed after the lid 71 is opened from 70. That is, the fastening lever 76 is rotated in the direction in which the lid 71 is opened to disengage the latch 75 and the locking piece 77, and the lid 71 is opened to move the upper and lower pressure contact rollers 21a and 21b from the driving roller 20. The pressure contact state is released, the cloth belt 80 is hung downward, and the lid portion 71 is held again in the closed state by the fixing lever 76 on the support base main body portion 70. Then, by winding the front end of the fabric belt 80 around the winding unit 12 described later, the fabric belt 80 is inserted into the driving roller 20 and the upper and lower pressure contact rollers 21a and 21b as shown in FIG. As described above, in the present invention, the cloth belt 80 can be attached to the tension drive unit 11 by a one-touch operation of operating the fastening device 73 and controlling the opening and closing of the lid 71. Becomes easy.

  Note that the tension driving unit 11 having the above configuration is connected to a delivery unit 52 described later by a connecting rod 85. Specifically, the sliding support base 13 and the tip of the stopper lever 67 of the delivery part 52 are connected by a connecting rod 85. This controls the feeding of the fabric belt 80 as will be described in detail later.

  The winding unit 12, which is another component of the winding mechanism unit 10, is provided collectively on a winding support base 30 having a substantially triangular side surface shape. That is, the winding support base 30 is composed of a pair of substantially triangular side plates and a bottom plate that covers the lower surface of the side plate, and the rear end of the side plate is fastened and fixed to the side surface of the cover plate 8 by the nut 31. Yes. In addition, insertion grooves 32a and 32b are formed substantially at the center of the winding support base 30, and a winding shaft 33 for winding the used fabric belt 80 is loosely fitted in the insertion grooves 32a and 32b. Therefore, the used cloth belt 80 is wound on the winding shaft 33 in a roll shape (hereinafter, this state is referred to as a post-use cloth belt roll 80b).

  The rotary shaft 35 passed to the upper rear end of the winding support base 30 has a motor shaft 36 having a plurality of (five in the illustrated example) winding cams 37 fixed to the tip thereof. A lever frame 34 is rotatably supported. Since the presser lever frame 34 extends substantially to the position where the insertion grooves 32a and 32b are formed, the take-up cam secured to the motor shaft 36 of the take-up motor 41 at the end of the presser lever frame 34. As shown in FIG. 4, reference numeral 37 is positioned obliquely forward of the wound post-use cloth belt roll 80b. Note that the take-up cam 37 has a gear-shaped structure having claws on the outer periphery in order to efficiently take up the cloth belt 80. Further, the cloth belt 80 is wound around the winding shaft 33 through the back side of the rotating shaft 35.

  Incidentally, a drive unit storage box 38 is formed on one side (left side) of the motor shaft 36 to which the plurality of winding cams 37 are fixed at substantially equal intervals. The drive storage box 38 is attached to the outside of the wide end portion of the pressing lever frame 34 described above, and a winding motor 41 is mounted therein. Accordingly, when the motor shaft 36 of the take-up motor 41 rotates, the take-up cam 37 takes up the cloth belt 80 drawn out by the pulling drive unit 11 in a roll shape. A spring 43 that urges the take-up cam 37 in a direction that always presses the post-use cloth belt roll 80b is stretched between the front end side of the presser lever frame 34 and the take-up support base 30. .

  As mentioned above, although the structure of the winding mechanism part 10 was explained in full detail, in the present Example, although the manual winding apparatus 90 showed the example provided in the tension drive part 11, this is not limited, for example, a winding part 12 may be provided. In this case, a manual winding device 90 is formed at one end of the winding shaft 33 in accordance with the above, and the lid 71 is released from the support base body 70 to drive the drive roller 20 and the upper and lower pressure contact rollers 21a and 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. Thus, the manual winding device 90 may be provided at an appropriate location on the side surface portion of the ball polishing and lifting device 1.

  Next, the configuration of the mounting mechanism unit 50 will be described with reference to FIGS. 2, 7, and 8. FIG. 7 is a perspective view of the mounting mechanism unit 50, and FIG. 8 is an enlarged side view of the mounting mechanism unit 50. In the figure, the mounting mechanism section 50 is composed of the cloth belt mounting section 51 for mounting the cloth belt 80 before use and the sending section 52 for sending out the mounted cloth belt 80 as described above. First, the configuration of the fabric belt mounting portion 51 will be described with reference to FIGS. 7 and 8. The fabric belt mounting portion 51 has a substantially triangular plate shape that is screwed to the both sides of the cover plate 8 with nuts 54. It is provided collectively on the mounting support base 53. That is, insertion grooves 55a and 55b (55a not shown) are formed at the tip of the mounting support base 53, and the cloth belt 80 before use is wound around the insertion grooves 55a and 55b in a roll shape. The take-up shaft 56 of the front cloth belt roll 80a is latched.

  In addition, a presser lever frame 58 having a presser roller 57 at its tip is pivotally supported by a pivot shaft 59 that is passed to the upper rear end of the mounting support base 53 so as to be swingable. Since the presser lever frame 58 extends slightly forward from the position where the fitting grooves 55a and 55b are formed, the presser roller 57 rotatably supported at the tip of the presser lever frame 58 is shown in FIG. As shown in Fig. 5, the cloth belt roll 80a before use is positioned obliquely forward. A spring 60 that urges the presser roller 57 to always press the pre-use cloth belt roll 80a is stretched between the front end side of the presser lever frame 58 and the mounting support base 53. Thereby, the cloth belt roller 80a before use is prevented from being naturally loosened, and the cloth belt 80 is smoothly supplied in a state where the cloth belt 80 extends cleanly.

  On the other hand, the delivery portion 52 is provided in a substantially square plate-like support base 61 that is screwed to the both sides of the cover plate 8 with nuts 62. That is, a large-diameter pressure contact roller 63 and small-diameter pressure contact rollers 64 and 65 arranged so as to be pressed obliquely up and down of the pressure contact roller 63 are passed to the support base 61. The cloth belt 80 is inserted between the large-diameter pressure contact roller 63 and the small-diameter pressure contact rollers 64 and 65 and is drawn downward. A ratchet gear 66 is fixed to the rotating shaft of the large-diameter pressure contact roller 63 outside the support base 61, and a stopper lever 67 is provided on the ratchet gear 66. One end of the stopper lever 67 is rotatably supported on the support base 61 by a support shaft 68, and one end of a connecting rod 85 is locked to the other end. An engaging claw 69 that engages with the teeth of the ratchet gear 66 is formed in the middle lower portion of the stopper lever 67. The other end of the connecting rod 85 is connected to the sliding support 13 of the pulling drive unit 11 of the winding mechanism unit 10 as described above.

  Next, the operation of attaching the fabric belt 80 to the ball polishing and lifting device 1 by the winding mechanism 10 and the mounting mechanism 50 having the above-described configuration will be described. The winding shaft 56 of the new pre-use fabric belt roll 80a. Is inserted into the insertion grooves 55a and 55b of the cloth belt mounting portion 51, and then the tip of the cloth belt 80 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, and the stopper lever 67 is engaged. In a state where the engagement is released, the large-diameter pressure contact roller 63 is manually rotated to pull out the cloth belt 80 having a necessary length downward. Thereafter, 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 the cloth belt 80 is interposed between the driving roller 20 of the tension driving unit 11 and the upper and lower pressure contact rollers 21a and 21b as described above. Insert. Further, the excessively pulled out fabric belt 80 is wound around the winding shaft 33, and in this state, the winding cam 37 of the presser lever frame 34 is brought into contact with the outer periphery of the used fabric belt roll 80b. After the cloth belt 80 is thus attached, 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, related operations between the winding mechanism unit 10 and the mounting mechanism unit 50 will be described. The cloth belt 80 is always forcedly pushed up by the frictional force while the pachinko balls are being transported by the transport belt 5 (while the ball polishing and lifting device 1 is being driven). For this reason, in the part of the tension drive part 11, since the cloth belt 80 will be in the loose state, it will be in the position where the sliding support stand 13 descend | falls. When the sliding support 13 is in the lowered position, the connecting rod 85 is also lowered, and the engaging claw 69 of the stopper lever 67 is engaged with the ratchet gear 66. For this reason, since the rotation of the large diameter pressure contact roller 63 is stopped, the supply of the cloth belt 80 by the large diameter pressure contact roller 63 and the small diameter pressure contact rollers 64 and 65 is also stopped. In such a state, the fabric belt 80 is not pushed up by the frictional force of the conveyor belt 5, and the fabric belt 80 does not loosen any more.

  Next, when winding the fabric 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 unit 10 are rotationally driven. Therefore, the fabric belt 80 is always wound, but since the tension motor 17 is driven, the fabric belt 80 is pulled in the tension drive unit 11. When the retraction is continued, the sliding support base 13 starts to rise, and finally rises to a position where the engagement between the engagement 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 feeding of the cloth belt 80 by the large-diameter pressure contact roller 63 and the small-diameter pressure contact rollers 64 and 65 is started, and a predetermined length (of the cover plate 8) is started. After winding the fabric belt 80 by the length), the tension motor 17 and the winding motor 41 are stopped. The rotational speed of the tension motor 17 and the winding motor 41 may be the same speed, or the rotational speed of the winding motor 41 may be slightly slower than the rotational speed of the tension motor 17.

As is apparent from the above description, in the present embodiment, the movement control of the fabric belt 80 is performed by being controlled by the tension driving unit 11 and the sending unit 52. That is, the cloth belt 80 is locked and the supply is stopped while the ball polishing and lifting apparatus 1 is driven, and the lock is released and the cloth belt 80 can be moved while the ball polishing and lifting apparatus 1 is stopped. It is controlled. In addition, since the moving speed of the fabric belt 80 is substantially determined by the capacity of the tension motor 17, it is sufficient to select the tension motor 17 that matches the desired winding speed. For example, if the rotation speed of the tension motor is 30 rpm and the diameter of the motor shaft 19 is 20 mm, the length of the cloth belt 80 that moves in one minute is:
20 × π × 30 ≒ 1884mm
It becomes.

  The above-described automatic winding operation control of the fabric belt 80 is executed according to the flowcharts shown in FIGS. 9 is a main process (main routine) of the winding operation of the fabric belt 80 in the present invention, FIG. 10 is a stop process of the ball polishing and lifting device 1, and FIG. 11 is a movement process of the fabric belt 80. It is. First, in FIG. 9, it is determined in step (hereinafter abbreviated as S) 100 whether or not the business has ended. If the business is in business, the operation of returning to S100 is repeated again. S120 is a subroutine that defines a stop process of the ball polishing and lifting device 1, and as shown in FIG. 10, first, pachinko balls that flow down to the introduction basket 6 of the ball polishing and lifting device 1 are stopped in S121. This stopping method is performed, for example, by controlling the opening and closing of the ball outlet by providing an opening / closing plate that is operated by a motor or the like on the side wall of a ball storage tank (not shown).

  Next, the process proceeds to S122, whether or not the pachinko balls remain in the ball polishing and lifting device 1, that is, all the pachinko balls that have entered the ball polishing and lifting device 1 have flowed out of the ball discharge port 7 (see FIG. 1). If there are still pachinko balls in the ball polishing and lifting apparatus 1, the operation of returning to S122 is repeated again. If all the pachinko balls have flowed out, the process proceeds to S123, where the ball polishing and lifting apparatus 1 Is turned off, the ball polishing and lifting device 1 is stopped, and the process returns to the main routine. Then, the process proceeds to S140, and it is determined whether or not the dirt sensor 88 that checks the cloth belt 80 for dirt is ON.

  As shown by the wavy line in FIG. 1, the dirt sensor 88 is provided on both side walls of the upper cover 7 of the ball polishing and lifting device 1, and uses reflection of light composed of the light emitting portion 89a and the light receiving portion 89b. It is a light sensor. The light emitted from the light emitting portion 89a is incident on the ball polishing surface of the fabric belt 80 at an approach angle θ, for example, and is reflected by the fabric belt 80 to reach the light receiving portion 89b. In this case, since the angle of the reflected light is the same as the approach angle θ, the light emitting unit 89a and the light receiving unit 89b may be installed at a position that satisfies the condition. As long as the polished surface of the fabric belt 80 is clean, the color of the fabric belt 80 is also white, the amount of light reaching the light receiving portion 89b increases, and the dirt sensor 88 is OFF. When the dirt on the polished surface of the fabric belt 80 becomes severe, the color of the fabric belt 80 becomes darker, so that the light emitted from the light emitting portion 89a is absorbed to some extent by the fabric belt 80 and reaches the light receiving portion 89b. The amount of light decreases, and the dirt sensor 88 is turned on when the amount of light falls below a set value. If it is determined in S140 that the dirt sensor 88 is OFF, the main routine is finished as it is, and if it is determined ON, the process proceeds to S150.

  S150 is a subroutine for defining the movement process of the fabric belt 80. 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, the process proceeds to S152, in which it is determined whether the replacement count and the movement count count are the same.

Here, the number of replacements is a value of how many times the cloth belt 80 can be moved, and an initial setting is required. For example, if the height of the cover plate 8 of the ball polishing and lifting device 1 is 2400 mm and the length of the cloth belt 80 is 25000 mm, the length of the dirty cloth belt 80 that is moved once is almost equal to the height of the cover plate 8. So
25000 ÷ 2400 ≒ 10.4167
Thus, the positive number part obtained by rounding down the decimal point of the above solution is the initial set value, and in this case, it is 10.

  When the number of times of replacement becomes equal to the number of times of movement, the process proceeds to S153 to display a cloth belt 80 replacement notice (not shown) and then proceeds to S155. This cloth belt 80 replacement notice lamp is lit or blinked by placing it in a place that can be easily seen by the store clerk, such as the edge of a pachinko island stand, or it can be lit by incorporating a pilot lamp or LED in a computer in the hall management room. And good.

  On the other hand, when the number of replacements is not equal to the number of movement counts in S152, the process proceeds to S154, and the magnitude of the number of replacements and the number of movement counts is determined. If the number of replacements is greater than the number of movement counts, the process proceeds to S155, the fabric belt 80 is moved for a predetermined section, and then the process returns to the main routine, and the main routine ends. In S154, if the number of replacements is smaller than the number of movement counts, the process proceeds to S156 to display the cloth belt 80 replacement rod (not shown). The cloth belt 80 replacement hook is formed in accordance with the above-described cloth belt 80 replacement warning lamp. Then, the process shifts to S157, the cloth belt 80 is replaced, the process shifts to S158, the movement count is set to 0, the process returns to the main routine, and the main routine ends.

  In this way, the cloth belt 80 is judged to be dirty by the dirt sensor 88 at the time when the pachinko hall is closed for a day, and when the dirt is severe, the dirt sensor 88 is turned on, and the cloth belt 80 is moved to a predetermined section ( The height of the cover plate 8) is automatically wound to prepare for the opening of the next day. Further, when the cloth belt 80 approaches the end, the cloth belt 80 replacement notice lamp or the replacement lamp is lit, so that it is possible to easily grasp the timing for replacing the cloth belt 80 with a new one. Further, as means for winding the cloth belt 80 of S155 described above for a predetermined section, a time necessary for winding the section is calculated in advance from the height of the cover plate 8 and the winding speed of the tension motor 17, and the time A method of driving the tension motor 17 only, a method of controlling the tension motor 17 based on the detection signal of the dirt sensor 88, and the like are 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 taken up, the dirt sensor What is necessary is just to rotate the winding lever of the manual winding apparatus 90 until 88 will be in an OFF state.

  Next, another embodiment of the operation control of the automatic winding of the fabric 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 fabric belt 80. In the figure, it is determined whether or not the dirt sensor 88 is ON in S200. The returning operation is repeated, and if it is ON, the process proceeds to S220. In S220, the stop processing of the above-described ball polishing and lifting device 1 shown in FIG. 10 is performed and the process proceeds to S240, and in S240, the movement process of the cloth belt 80 illustrated in FIG. 11 is performed and the process proceeds to S260. . Then, in S260, it is determined whether or not it is in business. If it is not in business, the main routine is terminated as it is, and if it is in business, the process proceeds to S280. S280 is a subroutine that defines the starting process of the ball polishing and lifting device 1, and as shown in FIG. 13, first, the power of the ball polishing and lifting device 1 is turned on in S281 and the process proceeds to S282. After waiting for a certain time until the speed reaches the normal speed, the process proceeds to S283. Then, in S283, the opening / closing plate of the above-described ball storage tank is opened on the introduction basket 6 of the ball polishing / lifting device 1 to allow the pachinko balls to flow down, and then the process returns to the main routine, and the process proceeds to S200 again.

  As is apparent from the above description, in this other embodiment, the dirt sensor 88 is activated not only at the end of the business but also during the business, and when the cloth belt 80 is extremely dirty, the ball polishing is temporarily performed. The feeding device 1 is stopped and the fabric belt 80 is wound up. Therefore, the fabric belt 80 can always be kept clean, and a clean pachinko ball can be supplied to the player.

  It should be noted that a switch or the like for forcibly driving the tension motor 17 to wind the cloth belt 80 regardless of the dirt sensor 88 may be provided at an appropriate location of the ball polishing and lifting device 1. In this case, it becomes effective when the automatic winding of the fabric belt 80 is hindered due to troubles of the dirt sensor 88 and other devices. As this configuration, for example, an AUTO switch for automatically winding the fabric belt 80, an ON switch for winding by electrical means as needed, and an OFF switch for winding by manual means at any time are provided as desired. What is necessary is just to execute by turning on the switch corresponding to the winding method. Further, when the replacement notice or replacement bag of the fabric belt 80 is displayed, the end portion of the old fabric belt 80 and the start end portion of the new fabric belt 80 with the old fabric belt 80 attached to the ball polishing and lifting device 1. Are connected in advance by appropriate means to form a series, and after the new cloth belt 80 is mounted on the above-described cloth belt mounting section 51, the cloth belt 80 is wound, and the connecting portion is the above-described winding section. 12 and then the old fabric belt 80 and the new fabric belt 80 may be disconnected. With such a configuration, the mounting mechanism 50 generated when the above-described fabric belt 80 is replaced, the work of inserting the fabric belt 80 into the take-up mechanism 10, and the delivery of the fabric belt 80 to the cover plate 8. The work is omitted, the efficiency of replacing the cloth belt 80 is improved, and a method of using the cloth belt 80 without waste (no use) can be realized.

  As described in detail above, in the ball polishing and lifting apparatus 1 of the present embodiment, the cloth belt 80 is automatically moved in a short time when the cloth belt 80 is extremely dirty by the dirt sensor 88 that determines the dirt state of the cloth belt 80. Therefore, it is not necessary to perform the winding operation of the fabric belt 80 in a narrow island, and the winding movement of the soiled fabric belt 80 can be easily performed. Further, the cloth belt 80 can be easily replaced by a one-touch operation, and the used cloth belt 80 is wound in a roll shape, so that the place for placing it can be reduced. In addition, since the manual winding device 90 is provided, the cloth belt 80 can be easily wound even if the automatic winding device is not activated due to some trouble of the device.
