The storage device 19 is a box that simply stores and stores the polishing belt 20 that has been rolled up before use, and will not be described in detail below. However, the installation location thereof is a guide rail 11 described later. It is installed on the floor which is lower than the opening and closing position.

  First, the winding device 60 constituting the winding mechanism section 22 will be described with reference to FIGS. 3 to 5. FIG. 3 is a perspective view showing the winding device 60 attached to the guide rail 11, and FIG. 4 is a perspective view showing a state in which the polishing belt 20 wound up in a roll shape is removed from the winding device 60. FIG. 5 is a side view seen from the drive unit of the winding device 60.

  The winding device 60 is attached to the central portion of the back surface of the guide rail 11, and as shown in FIG. 3, the winding device 60 is formed in a box shape with one side opened by a sheet metal, and the used polishing belt 20 is wound inside. It is stored in the removed state. The winding device 60 includes a base member 61 that forms the base of the winding device 60, a protective cover 62 for protecting the pulleys 85, 86, the slip belt 87, and the like attached to the outside of the base member 61, and a winding device. An opening / closing cover 63 that opens when the polishing belt 20 wound up by the apparatus 60 is taken out, a winding shaft 64 for winding the polishing belt 20, and end faces on both sides of the polishing belt 20 when winding the polishing belt 20. And side covers 65 and 66 for aligning.

  The base member 61 is formed in a box shape in which the entire circumference is bent in the same direction to form a wall surface, and one side surface is opened by the wall surface. An open / close cover 63 is attached to one side of the base member 61 (right side in FIG. 3) via a hinge 72 attached by an attaching screw 72a so as to be freely opened and closed. Since the fixed magnet 71 is attached to the right end surface of the upper wall surface of the base member 61 by the mounting screw 71a, the opening / closing cover 63 is attracted to the fixing magnet 71 when the opening / closing cover 63 is closed, and the opening / closing cover 63 is fixed to the base member 61. Further, as shown in FIG. 4, the wall surface on the opening / closing cover 63 side of the wall surface is provided with a notch 68 having a size that allows the wound polishing belt 20 and the side cover 65 to be pulled out. Is formed.

  Further, on the other side of the base member 61 (on the left side in FIG. 3), a drive unit composed of a drive pulley 85, a driven pulley 86, and a slip belt 87 is formed outside the base member 61, and this drive unit is protected. A protective cover 62 is attached detachably by a mounting screw 62a. Further, a motor 70 is mounted on the upper surface of the side wall surface of the protective cover 62 of the base member 61 via a gear head 69, and a drive pulley 85 is attached to an output shaft 82 of the gear head 69 as shown in FIG. It is worn. The gear head 69 is attached by a mounting screw 84 a inserted through a mounting elongated hole 84 drilled in the wall surface of the base member 61, and the output shaft 82 is similarly inserted into an output shaft insertion hole 83 drilled in the wall surface of the base member 61. It is inserted. Since the mounting elongated hole 84 and the output shaft insertion hole 83 are long in the vertical direction, the mounting position of the gear head 69 in the vertical direction is within the range of the length of the mounting elongated hole 84 and the output shaft insertion hole 83. Adjust and adjust the tension of the slip belt. In addition, a winding shaft 64 is pivotally supported via a bearing (not shown) at a substantially vertical center of the side wall surface of the protective cover 62 of the base member 61. A driven pulley 86 is attached to the shaft end of the winding shaft 64 on the protective cover 62 side.

  Between the driving pulley 85 and the driven pulley 86, a slip belt 87 made of a material having elasticity such as rubber and having a relatively large friction coefficient is stretched. The slip belt 87 has a circular cross section, and the outer peripheral cross sections of the drive pulley 85 and the driven pulley 86 are semicircular. Therefore, the rotation is not transmitted by engaging the unevenness like the timing belt and the timing pulley, but the rotation is transmitted by the frictional force between the slip belt 87, the drive pulley 85, and the driven pulley 86. .

  Thus, by rotating the motor 70, the rotation of the motor 70 is output to the output shaft 82 of the gear head 69 to rotate the drive pulley 85, and the rotation of the drive pulley 85 causes the frictional force between the drive pulley 85 and the slip belt 87. Thus, the slip belt 87 is rotated. Further, the rotation of the slip belt 87 rotates the driven pulley 85 by the frictional force between the slip belt 87 and the driven pulley 85, and the driven pulley 85 rotates, whereby the winding shaft 64 rotates.

  Further, two attachment pieces 67 are attached to the back side of the base member 61 at the left and right. An attachment groove 81 through which an attachment screw (not shown) for attaching the winding device 60 to the guide rail 11 is inserted is formed in the attachment piece 67. Thus, the winding piece 67 is inserted by inserting the mounting piece 67 so as to sandwich the guide rail 11 and locking the mounting groove 81 with a mounting screw screwed to the side surface of the guide rail 11 and then tightening the mounting screw. 60 is fixed to the guide rail 11.

  The open / close cover 63 is formed in a trapezoidal shape by sheet metal, and is attached to the base member 61 by the hinge 72 so as to be openable and closable as described above. A U-shaped notch is formed at a position corresponding to the end of the take-up shaft 64 at approximately the center in the vertical direction of the opening / closing cover 63, and has a recess substantially the same shape as the notch. A bearing stand 74 is attached to the open / close cover 63 by an attaching screw 74a. At this time, the bearing base 74 is attached so that the notch and the concave portion of the bearing base 74 overlap. Further, a handle 73 used for opening and closing the opening / closing cover 63 is attached to the upper side of the bearing base 74 by an attaching screw 73a.

  The winding shaft 64 is formed of a steel bar, and is rotatably attached to the side wall surface of the protective cover 62 of the base member 61 through the bearing as described above. Although not shown, the winding shaft 64 has a diameter near the bearing that is larger than the diameter of the winding portion of the polishing belt 20 and has a stepped shape. On the shaft of the winding part of the polishing belt 20 of the winding shaft 64, a locking piece 78 serving as a trigger for winding the polishing belt 20 comes into contact with the stepped portion of the winding shaft 64 and stops. It is fixed by a screw 78a so as to cover the winding portion of the polishing belt 20 of the winding shaft 64. The locking piece 78 is formed in a cylindrical shape, and the diameter thereof is substantially the same as the diameter of the portion in the vicinity of the bearing of the winding shaft 64. Further, a part of the end of the locking piece 78 on the side of the opening / closing cover 63 protrudes in the axial direction to form a convex portion, and a gap is formed between the lower surface of the convex portion and the winding shaft 64. Yes. On the other hand, a V-shaped groove (not shown) is formed on the outer periphery of the vicinity of the bearing of the take-up shaft 64. This is for mounting the side cover 66 on the take-up shaft 64. is there.

  The side cover 66 is attached to the side cover attachment member 79 by means of attachment screws 79a, and an insertion hole for inserting a portion near the bearing of the take-up shaft 64 is formed at the center of the side cover attachment member 79. It is installed. The front end of a ball bearing (not shown) protrudes from the wall surface of this insertion hole at three locations, and this ball bearing is embedded in the side cover mounting member 79. The ball bearing is pressed toward the insertion hole by a spring embedded in the side cover mounting member 79, and is buried in the side cover mounting member 79 by applying pressure to the tip. .

  Thus, when the side cover mounting member 79 with the side cover 66 attached is inserted into the vicinity of the bearing of the take-up shaft 64, the ball bearing is pressed by the portion near the bearing of the take-up shaft 64 and the inside of the side cover mounting member 79. Buried in. Then, the ball bearing once buried in the side cover mounting member 79 protrudes again onto the wall surface of the insertion hole at the position of the V-shaped groove in the vicinity of the bearing of the winding shaft 64 and fits into the V-shaped groove. It becomes. In this way, the side cover attachment member 79 is attached to the take-up shaft 64. However, since the side cover attachment member 79 is not fixed to the take-up shaft 64, the side cover 66 is It is rotatable with respect to the take-up shaft 64 and is detachable.

  The side cover 66 is formed in a circular shape from a resin material such as acrylic. Further, a V-shaped groove (not shown) is formed around the winding shaft 64 in the vicinity of the front end portion of the winding shaft 64 on the opening / closing cover 63 side. This is for mounting the side cover 65. Similar to the side cover 66, the side cover 65 is formed in a circular shape by a resin material such as acrylic, and is attached to the side cover attachment member 76 by an attachment screw (not shown).

  As in the case where the side cover 66 is mounted in the vicinity of the bearing of the winding shaft 64, when the side cover mounting member 76 with the side cover 65 mounted is inserted into the winding shaft 64, the ball bearing is wound. It is pressed by the spindle 64 and buried in the side cover mounting member 76. Then, the ball bearing once buried in the side cover mounting member 76 protrudes again on the wall surface of the insertion hole at the position of the V-shaped groove at the front end portion of the winding shaft 64 and fits into the V-shaped groove. . In this way, the side cover attachment member 76 is attached to the take-up shaft 64, but the side cover attachment member 76 is not fixed to the take-up shaft 64, so the side cover 65 is It is rotatable with respect to the take-up shaft 64 and is detachable.

  A bearing 75 is rotatably attached to the side cover attaching member 76 via a bearing 77. The bearing 75 is formed in a shape in which a plurality of disks having different diameters are overlapped, and the diameter of the smallest diameter portion formed at the tip is slightly smaller than the diameter of the recess of the bearing base 74. It is formed to the extent. Thus, when the side cover 65 is attached to the take-up shaft 64 and the open / close cover 63 is closed, the tip portion of the bearing 75 is fitted into the recess of the bearing base 74 attached to the open / close cover 63, and the take-up shaft 64 is moved. Will be supported.

  A method for attaching and detaching the polishing belt to and from the winding device 60 configured as above will be described. First, the opening / closing cover 63 on the side of the winding device 60 is opened, and the side cover 65 is removed from the winding shaft 64. After the side cover 65 is extracted from the winding shaft 64, the fitting insertion portion 80 formed at the end of the polishing belt 20 is inserted into the winding shaft 64. In addition, the width dimension of the polishing belt 20 is gradually reduced toward the fitting insertion portion 80 side. When the polishing belt 20 is inserted into the take-up shaft 64, as shown in FIG. 3, the fitting insertion portion 80 is inserted into the gap between the convex portion formed on the locking piece 78 and the take-up shaft 64, The polishing belt 20 is attached to the take-up shaft 64 by pressing the fitting insertion portion 80 toward the protective cover 62 until the side end portion of the portion 80 contacts the locking piece 78. After the polishing belt 20 is attached to the fitting insertion portion 80, the side cover 65 is attached to the take-up shaft 64, and the opened opening / closing cover 63 is closed to thereby close the bearing base 74 of the opening / closing cover 63 as described above. Is inserted into the bearing 75, the winding shaft 64 is supported, and the polishing belt 20 is attached to the winding device 60.

  As described above, after the polishing belt 20 is mounted on the winding device 60, the motor 70 is driven to rotate, whereby the rotation is transmitted to the winding shaft 64 via the drive pulley 85, the slip belt 87, and the driven pulley 86. The take-up shaft 64 rotates. At this time, the winding shaft 64 rotates in the clockwise direction when viewed from the opening / closing cover 63 side. When the winding shaft 64 is rotated, the locking piece 78 is also rotated at the same time. However, when the locking piece 78 is rotated, the convex portion at the tip of the locking piece 78 locks the fitting insertion portion 80 of the polishing belt 20. Therefore, the polishing belt 20 is wound around the winding shaft 64. As described above, the operation of attaching the polishing belt when winding the polishing belt can be easily performed because it is completed simply by inserting the insertion portion of the polishing belt into the winding shaft. Further, the polishing belt 20 is gradually wound up according to the rotation of the winding shaft 64, but side covers 65, 66 that rotate together with the winding shaft 64 are mounted on both sides of the winding shaft 64. The covers 65 and 66 are wound while the end portions on both sides of the polishing belt 20 are aligned. At this time, even if the side end portion of the polishing belt 20 wound in a roll shape while being displaced in the winding axis direction contacts the side covers 65 and 66, the side covers 65 and 66 also move together with the roll-shaped polishing belt 20. Since it rotates, the frictional resistance between the roll-shaped polishing belt 20 and the side covers 65 and 66 can be reduced, and the winding of the polishing belt 20 can be smoothly performed by preventing the motor 70 from being burdened. It can be carried out.

  Since the roll diameter gradually increases as the polishing belt 20 is wound into a roll, the winding amount of the polishing belt 20 gradually increases when the rotation of the motor 70 is constant. However, since the pulling device 110 pulls the polishing belt 20 and sends it to the winding device 60 is constant, the winding amount of the polishing belt 20 of the winding device 60 is the pulling amount of the polishing belt 20 of the pulling device 110. When the value exceeds the value, the amount of the polishing belt 20 taken up by the take-up device 60 will be insufficient. In this case, if the rotation of the motor 70 is transmitted by meshing the pulley and the belt as in the timing belt, a large load is applied to the motor 70, the motor 70 is stopped, and the load is applied to the motor 70. However, as described above, the transmission of the rotation of the motor 70 to the winding shaft 64 is performed by the frictional force between the driving pulley 85 and the driven pulley 86 and the slip belt 87. When the winding amount of the polishing belt 20 exceeds the pulling amount of the polishing belt 20 of the tension device 110, the slip belt 87 slips with respect to the driving pulley 85 or the driven pulley 86. For this reason, the motor 70 does not stop and a load is not applied to the motor 70. Further, in order to remove the wound polishing belt 20 from the winding device 60, the procedure for attaching the polishing belt 20 is reversed. That is, after opening the opening / closing cover 63, the side cover 65 is removed and the winding is performed. By pulling the polishing belt 20 forward, the polishing belt can be easily removed.

  Next, the tensioning device 110 constituting the winding mechanism unit 22 will be described with reference to FIG. FIG. 6 is a perspective view showing a state in which the tension device 110 is opened. The tension device 110 is attached slightly above the center of the back surface of the guide rail 11. As shown in FIG. 6, the tension device 110 is centered on an attachment main body 111 to which the motor 123 and the main roller 125 are fixed, and a support shaft (not shown) fixed to the attachment main body 111 with an attachment screw 151. And an opening / closing cover body 112 that is provided so as to be freely opened and closed and to which the pressure rollers 144 and 145 are swingably mounted. The polishing belt 20 is hung on the front side of the main roller 125 with the opening / closing cover body 112 opened. After that, the opening / closing cover body 112 is closed and locked by the locking metal member 120 so that the polishing belt 20 is sandwiched between the main roller 125 and the pressure contact rollers 144 and 145 in a meandering manner.

  The attachment main body 111 is configured such that the components are attached together on the main base body 113 that forms the base body of the attachment main body 111. The main base body 113 is bent at both sides at right angles in the same direction to form wall surfaces, and the upper and lower ends of both wall surfaces are also bent outward. At the upper and lower ends of the open side wall (right side in FIG. 6) of the main base 113, mounting plates 114 formed by bending three sides are attached by mounting screws 122. A bent portion located on the opening / closing cover body 112 side of the mounting plate 114 forms an adjustment screw contact portion 121. In addition, on the upper and lower sides of the outer surface of the mounting plate 114, locking metal fittings 120 are attached for fixing the tensioning device 110 in a closed state when the tensioning device 110 is closed.

  On the other hand, a motor 123 is mounted on the upper surface of the fulcrum side (left side in FIG. 6) of the main base 113 via a gear head 124, and the main roller 125 is also connected to the lower portion of the fulcrum side wall surface via a bearing 126. Is supported. Although not shown, the bearing 126 is also mounted on the open side wall surface, and the main roller 125 is pivotally supported by the bearings 126 on both sides. An output shaft (not shown) projects from the gear head 124 to the outside of the fulcrum side wall surface of the main base 113, and a drive pulley 127 is fixed to the shaft end of the output shaft. A shaft (not shown) that supports the main roller 125 protrudes outside the fulcrum side wall surface of the main base 113, and a driven pulley 128 is fixed to the shaft end of the shaft. A timing belt 129 is stretched between the driving pulley 127 and the driven pulley 128. Accordingly, when the motor 123 is driven, the driving force is transmitted through the driving pulley 127, the timing belt 129, and the driven pulley 128, and the main roller 125 is driven to rotate. The outer periphery of the main roller 125 is subjected to diamond cutting to increase the frictional force with the polishing belt 20.

  In addition, a guide member 115 for inserting the polishing belt 20 is provided symmetrically on the upper back side of the main base 113. The guide member 115 has an upper portion bent into a U-shaped cross section to form a bent portion 116, and the abrasive belt 20 is inserted into the U-shaped portion to guide the abrasive belt 20 from the left and right. is there. Further, L-shaped connecting pieces (not shown) are attached to the left and right of the main base 113 below the guide member 115. Two elongated slots (not shown) are drilled on the upright surface of the connecting piece, and the elongated main hole 113 is attached to the mounting piece 117 so that the main base 113 can slide up and down. Is for. The attachment piece 117 is formed in a U-shaped cross section, and an attachment groove 119 and an attachment long hole (through which an attachment screw (not shown) for attaching the entire tensioning device 110 to the guide rail 11 is inserted in the bent portion. (Not shown) is formed. Further, the inner dimension of the bent portion of the mounting piece 117 is formed at substantially the same interval as the width dimension of the guide rail 11. A connecting member 118 having a U-shaped cross-section is joined to the surface of the mounting piece 117 on the main base 113 side, and a screw hole (not shown) is formed on the upright surface of the connecting member 118. Are drilled in two places at the top and bottom. Thus, the attachment piece 117 is attached to the main base 113 by inserting an attachment screw into the slide long hole formed in the connection piece and screwing the attachment screw into the screw hole of the connection member 118. It will be. At this time, as described above, the main base 113 is attached to the attachment piece 117 so as to be slidable in the vertical direction by the length of the slide long hole.

  Thus, after inserting the attachment piece 117 so as to sandwich the guide rail 11 and locking the attachment groove 119 formed in the attachment piece 117 to a bolt (not shown) screwed to the side surface of the guide rail 11, The tensioning device 110 is fixed to the guide rail 11 by tightening the bolt. At this time, as described above, the main base 113 is attached to the attachment piece 117 so as to be slidable up and down. It will be attached movably.

  On the other hand, the opening / closing cover body 112 is a part in which the components are assembled and attached to the cover base 140 forming the base of the opening / closing cover body 112. The cover base 140 is formed in a box shape with the rear open, and support members 143 are fixed to two upper and lower portions in the center of the inner side surface in the left-right direction. Between the two support members 143, the roller mounting plate 141 is pivotally supported by a support shaft 142 inserted through the support member 143. The roller mounting plate 141 is formed in a box shape with one open surface, and press contact rollers 144 and 145 formed of rubber columnar material are rotatably supported on the open surface side. Further, on both side surfaces of the roller mounting plate 141, a main roller insertion portion 146 in which the main roller 125 is located when the opening / closing cover body 112 is closed is formed between the pressure roller 144 and the pressure roller 145.

  Further, a screw (not shown) is embedded in one pressure contact roller 144, and correspondingly, a bottom surface portion of the roller mounting plate 141 is used as a polishing belt state detection unit and a polishing belt movement amount detection unit. A slip detection sensor 147 is attached via a sensor base 148. On the upper and lower sides of the open side end portion of the cover base 140, locking pieces 149 that are engaged with the locking metal fittings 120 when the opening / closing cover body 112 is closed are attached by mounting screws 150. In the state where the opening / closing cover body 112 is closed with respect to the attachment main body 111, the pressure rollers 144 and 145 are positioned obliquely above and below the main roller 125.

  Further, an adjustment screw for adjusting a gap between the end of the open / close cover body 112 and the end of the mounting body 111 when the open / close cover body 112 is closed is provided above and below the open side end of the cover base 140. (Not shown) is provided. This adjustment screw is screwed into a screw hole (not shown) drilled in the end of the opening / closing cover body 112, and when the opening / closing cover body 112 is closed, the tip of the adjustment screw is attached to the mounting body 111. The adjusting screw contact portion 121 is contacted. A fixing nut (not shown) for fixing the adjusting screw is screwed into the adjusting screw between the screw head of the adjusting screw and the cover base 140.

  In the tensioning device 110 configured as described above, the polishing belt 20 having an arbitrary thickness is attached to the tensioning device 110 while appropriately adjusting the gap between the opening / closing cover body 112 and the mounting body 111 according to the thickness. The procedure is described below. First, the opening / closing cover body 112 is opened, the fixing nut fixing the adjusting screw is loosened, and then the adjusting screw is sufficiently loosened so as not to be detached from the cover base 140. Next, after the polishing belt 20 is hung on the front surface side of the main roller 125 of the attachment main body 111, the opening / closing cover body 112 is closed with the locking fitting 120. With the open / close cover body 112 closed, the adjustment screw is tightened until the tip of the adjustment screw comes into contact with the adjustment screw contact portion 121. At the position where the tip of the adjustment screw comes into contact with the adjustment screw contact portion 121, the loosened fixing nut is tightened to fix the adjustment screw. Thereby, the gap dimension between the opening / closing cover body 112 and the mounting body 111 is determined according to the thickness of the sandwiched polishing belt 20. The opening / closing cover body 112 is fixed to the attachment main body 111 simply by locking the locking metal piece 120 to the locking piece 149, and the polishing belt 20 is attached to the tensioning device 110 in an optimum state. At this time, when the sandwiched polishing belt 20 is thin, the gap between the opening / closing cover body 112 and the mounting body 111 is small, and the adjusting screw is not tightened deeply. On the other hand, when the sandwiched polishing belt 20 is thick, the gap between the opening / closing cover body 112 and the mounting body 111 becomes large, and the adjusting screw is tightened deeply. As described above, the polishing belt 20 having an arbitrary thickness can be attached depending on the degree of tightening of the adjusting screw.

  Here, as described above, when the thick polishing belt 20 is sandwiched, the opening / closing cover body 112 is fixed to the attachment main body 111 at an angle. For this reason, when the pressure rollers 144 and 145 as in the conventional product are fixed in parallel to the opening / closing cover body 112, the pressure rollers 144 and 145 are fixed at an angle with respect to the main roller 125. become. When the polishing belt 20 is delivered in this state, the polishing belt 20 is displaced in the left-right direction because no pressure is uniformly applied to the entire polishing belt 20. However, since the pressing rollers 144 and 145 in this embodiment are pivotally supported with respect to the opening / closing cover body 112, even when the opening / closing cover body 112 is fixed at an angle with respect to the mounting body 111. When the opening / closing cover body 112 is closed, the pressure contact rollers 144 and 145 follow the main roller 125 and are pressed in parallel to the main roller 125. For this reason, when the polishing belt 20 is sent out, pressure is uniformly applied to the entire polishing belt 20, and the polishing belt 20 does not shift in the left-right direction.

  The tensioning device 110 configured as described above is meandered by the main roller 125 and the pressure rollers 144 and 145 when the motor 123 is rotated when a stop device 160 described below is in a non-stop state. The sandwiched polishing belt 20 pulls and moves the polishing belt 20 downward by the pressing force of the rollers 125, 144, and 145. At this time, the number of rotations of the pressure roller 144 is detected by detecting the rotation of the screw embedded in the pressure roller 144 by the slip detection sensor 147, or the rotation time of the motor 123 exceeds the predetermined value. The motor 123 can be stopped when the predetermined time has elapsed. When the rotational speed of the pressure roller 144 is equal to or less than a predetermined value and the motor 123 is stopped, the polishing belt 20 is not normally pulled due to slip or the like. 110 abnormalities are reported.

  Next, the stopping device 160 constituting the mounting mechanism unit 23 will be described with reference to FIG. FIG. 7 is a perspective view showing a state in which the stop device 160 is opened. The stop device 160 is attached to the lower part of the back surface of the guide rail 11. As shown in FIG. 7, the stop device 160 includes an attachment main body 161 to which the electromagnetic clutch mechanism 172 and the main roller 170 are fixed, and a support shaft (not shown) fixed to the attachment main body 161 with an attachment screw 201. And an opening / closing cover body 162 that is pivotably supported by the pressure-contact rollers 195 and 196, and the polishing belt 20 is attached to the main roller 170 with the opening / closing cover body 162 opened. After hanging down on the front surface side, the opening / closing cover body 162 is closed and locked by a locking metal fitting 173 so that the polishing belt 20 is sandwiched between the main roller 170 and the pressure rollers 195 and 196 in a meandering manner.

  The mounting main body 161 is composed of a main base body 163 that horizontally supports the main roller 170 at a substantially central position thereof, and a support base body 164 that covers the electromagnetic clutch mechanism 172. The main base 163 has shaft support side plates 175 and 176 on both sides in order to support the main roller 170 in the horizontal direction, and the electromagnetic clutch mechanism 172 is screwed to the back surface of one of the shaft support side plates 175. At the same time, a support base 164 formed in a U shape so as to cover the electromagnetic clutch mechanism 172 is fastened and fixed to a mounting piece projecting outward on the shaft support side plate 175 by a mounting screw 165. Yes. On the other (open side) shaft support side plate 176, a mounting plate 166 provided with a locking metal fitting 173 is attached to a mounting piece projecting outward from the top and bottom of the shaft support side plate 176. It is fixed by fastening. Further, an adjustment screw abutting portion 168 protrudes outward from the shaft support side plate 176. A space is formed between the shaft support side plate 176 and the mounting plate 166, and one end of the main roller 170 protrudes and is accommodated in this space.

  Further, a bearing 171 is fixed to the shaft support side plates 175 and 176 of the main base 163 at substantially the center thereof, and the main roller 170 is rotatably supported by the bearing 171. The other end of the main roller 170 passes through the bearing 171 of the shaft support side plate 175 and is connected to the electromagnetic clutch mechanism 172. The electromagnetic clutch mechanism 172 is allowed to rotate the main roller 170 when energized, and prohibited from rotating the main roller 170 when de-energized. The main roller 170 is formed of a metal cylindrical material, and when the outer peripheral surface is subjected to processing such as diamond cutting and the polishing belt 20 is pressure-bonded, the frictional force therebetween increases to be polished. The movement of the belt 20 is surely prevented.

  Further, the main base 163 is provided with a pair of attachment pieces 169 on the back side thereof. The inner dimension of the pair of mounting pieces 169 is formed at substantially the same interval as the lateral width dimension of the guide rail 11, and the mounting piece 169 is inserted so as to sandwich the guide rail 11, and is formed at substantially the center of the mounting piece 169. The stopping device 160 is fixed to the guide rail 11 by locking the mounting groove 174 to a mounting screw (not shown) screwed to the side surface of the guide rail 11 and then fastening the mounting screw. Note that the upper side of the main base 163 is bent inward, and a polishing belt insertion portion into which the polishing belt 20 is inserted is formed in front of the main substrate 163. The interval between the polishing belt insertion portions is formed to be extremely small, For example, the operation state of the stop device 160 is smoothly performed over a long period of time so that pachinko balls or large foreign matters that fall from above do not enter the inside of the stop device 160.

  On the other hand, the open / close cover body 162 is configured such that the components are assembled and attached to the cover base 190 that forms the base of the open / close cover body 162. The cover base 190 is formed in a box shape with the rear open, and support members (not shown) are fixed to two upper and lower portions in the center of the inner side surface in the left-right direction. Between the two support members, a roller mounting plate 194 is pivotally supported by a support shaft (not shown) inserted through the support member. The roller mounting plate 194 is formed in a box shape with one open surface, and press contact rollers 195 and 196 formed of a rubber columnar material are rotatably supported on the open surface side. Further, on both side surfaces of the roller mounting plate 194, a main roller insertion portion 197 in which the main roller 170 is located when the open / close cover body 162 is closed is formed between the pressure roller 195 and the pressure roller 196. In the state where the opening / closing cover body 162 is closed with respect to the mounting main body 161, the pressure rollers 195 and 196 are positioned obliquely above and below the main roller 170.

  Further, an adjustment screw for adjusting a clearance between the end of the open / close cover body 162 and the end of the mounting body 161 when the open / close cover body 162 is closed is provided above and below the open side end of the open / close cover body 162. 202 is provided. The adjustment screw 202 is screwed into a screw hole (not shown) drilled in the end of the opening / closing cover body 112, and when the opening / closing cover body 162 is closed, the tip of the adjustment screw 202 is attached. The main body 161 abuts on the adjusting screw abutting portion 168. A fixing nut 203 for fixing the adjustment screw 202 is screwed into the adjustment screw 202 between the screw head of the adjustment screw 202 and the cover base 190.

  In the stopping device 160 configured as described above, the polishing belt 20 having an arbitrary thickness is attached to the stopping device 160 while appropriately adjusting the gap between the opening / closing cover body 162 and the mounting body 161 according to the thickness. The procedure is described below. First, the opening / closing cover body 162 is opened, the fixing nut 203 fixing the adjusting screw 202 is loosened, and then the adjusting screw 202 is sufficiently loosened so as not to be detached from the cover base 190. Next, after the polishing belt 20 is hung on the front surface side of the main roller 170 of the attachment main body 161, the opening / closing cover body 162 is closed with the locking metal fitting 173. With the open / close cover body 162 closed, the adjustment screw 202 is tightened until the tip of the adjustment screw 202 comes into contact with the adjustment screw contact portion 168. The adjustment screw 202 is fixed by tightening the loosened fixing nut 203 at the position where the tip of the adjustment screw 202 is in contact with the adjustment screw contact portion 168. Thereby, the gap dimension between the opening / closing cover body 162 and the mounting body 161 is determined in accordance with the thickness of the sandwiched polishing belt 20. The opening / closing cover body 162 is fixed to the mounting body 161 simply by locking the locking metal fitting 173 to the locking piece 199 described later, and the polishing belt 20 is mounted in the stop device 160 in an optimal state. At this time, when the sandwiched polishing belt 20 is thin, the gap between the opening / closing cover body 162 and the mounting body 161 is small, and the adjusting screw 202 is not deeply tightened. On the other hand, when the sandwiched polishing belt 20 is thick, the gap between the opening / closing cover body 162 and the mounting body 161 becomes large, and the adjustment screw 202 is tightened deeply. As described above, the polishing belt 20 having an arbitrary thickness can be attached depending on the degree of tightening of the adjusting screw 202.

  Here, as described above, when the thick polishing belt 20 is sandwiched, the opening / closing cover body 162 is fixed to the attachment main body 161 at an angle. For this reason, when the pressure rollers 195 and 196 as in the conventional product are fixed in parallel to the open / close cover body 162, the pressure rollers 195 and 196 are fixed at an angle with respect to the main roller 170. become. When the polishing belt 20 is delivered in this state, the polishing belt 20 is displaced in the left-right direction because no pressure is uniformly applied to the entire polishing belt 20. However, since the pressure contact rollers 195 and 196 in this embodiment are pivotally supported with respect to the opening / closing cover body 162, even when the opening / closing cover body 162 is fixed to the mounting body 161 at an angle. When the open / close cover body 162 is closed, the pressure contact rollers 195 and 196 follow the main roller 170 and are pressed in parallel to the main roller 170. For this reason, when the polishing belt 20 is sent out, pressure is uniformly applied to the entire polishing belt 20, and the polishing belt 20 does not shift in the left-right direction.

  Therefore, when the polishing belt 20 is sandwiched between the main roller 170 and the pressure rollers 195 and 196, the polishing belt 20 is sandwiched so as to meander. For this reason, when the rotation of the main roller 170 is stopped by the electromagnetic clutch mechanism 172, the movement of the polishing belt 20 is surely stopped. Further, since the pressure rollers 195 and 196 are made of a rubber soft material, even if a minute foreign matter attached to the polishing belt 20 is caught between the main roller 170 and the pressure rollers 195 and 196 as it is, Foreign matter is not absorbed by the elastic force of the rubber of the rollers 195 and 196 and does not interfere with rotation.

  In addition to the above-described configuration, the opening / closing cover body 162 is provided with a polishing belt contact piece 198 on the back surface thereof, and a guide member 191 having bent portions 192 on which the both side ends of the polishing belt 20 are guided is mounted on the upper surface A locking piece 199 that is fastened by a screw 193 and is locked by being engaged with the buckle-type locking metal fitting 173 on the open side surface thereof is fastened by a mounting screw 200. Among these, the abrasive belt contact piece 198 has the following configuration and action.

  That is, a contact piece support member (not shown) is provided on both sides of the back surface of the opening / closing cover body 112, and the polishing belt contact piece 198 whose one end is always in contact with the polishing belt 20 with respect to the contact piece support member. It is pivotally supported. In addition, an opening (not shown) is opened at the center of the back surface of the opening / closing cover body 162, and a detection piece (not shown) of the position detection sensor 204 faces the opening. The position detection sensor 204 (polishing belt state detection means, polishing belt predetermined remaining amount detection means) presses a projection (not shown) of the position detection sensor 204 when the detection piece comes into contact with the polishing belt contact piece 198. The position of the polishing belt contact piece 198 is detected. Then, the polishing belt 20 stored in the storage device 19 comes into contact with the polishing belt contact piece 198 to bring the polishing belt contact piece 198 into contact with the back surface of the opening / closing cover body 162, and the upper surface of the opening / closing cover body 162. After being guided by the bent portion 192 of the guide member 191 and inserted into the polishing belt insertion portion formed at the upper portion of the stop device 160 and pulled out, the guide rail 11 is wound from the lower portion to the upper portion. The guide member 191 is provided on the upper surface of the opening / closing cover body 162, but may be provided anywhere as long as it is in front of the polishing belt insertion portion.

  The operation of the stopping device 160 configured as described above will be described. First, in a normal state (when the storage device 19 has the polishing belt 20), one end of the polishing belt contact piece 198 that contacts the polishing belt 20 is pulled up by the tension of the polishing belt 20 that is wound around the stop device 160. Since the polishing belt contact piece 198 is held vertically, the position detection sensor 204 detects the contact of the polishing belt contact piece 198. However, when the polishing belt 20 stored in the storage device 19 is used to the end and the end thereof is released from the storage device 19 (the polishing belt 20 is no longer in the storage device 19), the polishing belt 20 is rotated to the stop device 160. Since the tension of the mounted polishing belt 20 is loosened and one end of the polishing belt contact piece 198 that comes into contact with the polishing belt 20 cannot be pulled up, the polishing belt contact piece 198 swings in an inclined direction by its own weight. Then, since the position detection sensor 204 does not detect the contact of the polishing belt contact piece 198, a signal to that effect is derived to the outside. Therefore, the stop device 160 according to the present embodiment can detect that the polishing belt 20 of the storage device 19 has been used to the end and notify the outside, and can prompt the exchange of the polishing belt 20. In other words, the position detection sensor 204 of the stopping device 160 constitutes a predetermined remaining amount detecting unit for the polishing belt that detects an end state of one roll when the remaining amount of the polishing belt 20 reaches a predetermined amount.

  Further, when the polishing belt 20 is inserted into the stopping device 160, the polishing belt 20 is introduced along the bent portion 192 of the guide member 191 that corrects the deviation in the traveling direction of the polishing belt 20, so that, for example, the polishing belt 20 is stored. Even when the polishing belt 20 enters in an oblique direction with respect to the stopping device 160 when it is stored in a biased position in the device 19, the polishing belt 20 is moved to the main roller by the bent portion 192 of the guide member 191. 170 and the pressure rollers 195 and 196 do not enter obliquely but enter in an accurate state, and as a result, the advantage that the polishing belt 20 maintains a predetermined accurate position until it is wound around the winding device 60. It is what has.

  In the case of the above-described embodiment, it is detected that the polishing belt 20 has been used to the end and notified to the outside, and by this notification, the guide belt 11 and the like are opened and closed to replace the polishing belt 20. However, in such notification of replacement of the polishing belt 20, it should be determined whether or not the polishing belt 20 should be replaced based on the winding amount at the time of detecting the end of one roll of the polishing belt 20. When it is determined that there is, the replacement notification of the polishing belt 20 is made. Hereinafter, the winding process of the polishing belt 20 including such replacement notification will be described with reference to FIGS.

  The “total length of the ball polishing lifting device” in the setting item display section 58 is an item for inputting the total length of the ball polishing lifting device 1 installed in the game island stand 30. In addition, the length of the ball polishing surface of the polishing belt 20 attached to the ball polishing / lifting device 1 is calculated by inputting the total length of the ball polishing / lifting device 1. Specifically, when “254 cm” is input as the total length of the ball polishing and lifting device 1 installed on the “1” game island stand 30, a value obtained by subtracting “27 cm” as a certain amount from this “254 cm”. "227cm" is the length of the polished surface.

  The “winding range” in the setting item display section 58 is an item for setting and inputting in advance a range for winding the used polishing belt 20 at the end of a day at the game hall. In FIG. 10, the case where “one side” is input so as to wind up one side of the polishing belt 20 (the whole surface of the ball polishing surface) in each of the game islands 30 of “1” to “6”. Illustrate. The winding range of the polishing belt 20 can be set to various winding ranges such as “half surface” in addition to “one surface”.

  The “total length of the polishing belt” in the setting item display section 58 is an item for inputting the total length of the polishing belt 20 attached to the ball polishing and lifting device 1. FIG. 10 illustrates a case where the polishing belt 20 having a total length of “1800 cm” is attached to each of the game islands 30 of “1” to “6” and “1800 cm” is input.

  The “ball return device” in the setting item display unit 58 is an item for inputting whether or not the ball return device 40 is provided at the island end of the game island stand 30. In FIG. 10, a ball return device 40 is provided for each of the game islands 30 of “1”, “3”, and “5”, while a ball return device 40 is provided for each of the game islands 30 of “2”, “4”, and “6”. It is input that the device 40 is not provided. As shown, “○” is displayed in the “1”, “3” and “5” fields of the game islands 30, while “2” and “4” are displayed. The case where “x” is displayed in the column of each game island stand 30 of “6” is illustrated.

  The “cleanliness level” of the setting item display section 58 is a determination level on the game side when determining whether or not to perform replacement notification of the polishing belt 20 in a state where one roll of the polishing belt 20 which will be described in detail later is completed. It is an item to input. FIG. 10 illustrates a case where the cleanliness level of “2” is set and inputted to the polishing belt 20 of each of the game islands 30 of “1” to “6”.

  Next, the winding process of the polishing belt 20 by the island control board 42 based on the management of the management device 50 will be described with reference to FIGS. As shown in FIG. 11, as the winding process of the polishing belt 20, the island control board 42 first determines whether or not an operation switch (not shown) for starting the winding operation provided in the management device 50 described above has been turned ON. That is, it is determined whether or not there is a winding operation signal (step S1). If the operation switch is not turned on, the winding process is terminated as it is. On the other hand, when the operation switch is turned on, the polishing belt winding operation start process (step S2) and the polishing belt winding amount control process (step S3). ) And polishing belt winding operation stop processing (step S4) are sequentially executed.

  In the polishing belt winding operation start processing in step S2, as shown in FIG. 12, the ball polishing / lifting device stop processing for stopping the driving of the ball polishing / lifting device 1 is executed (step S11), and then the conveyor belt is replaced. It is determined whether or not the flag is “1” (step S12). The conveyance belt replacement flag is set to “1” in step S42 described later in the polishing belt winding amount control process (step S3). If the polishing belt replacement flag is “0” in step S12 and it is not necessary to replace the polishing belt 20, the stop device 160 is set to the non-stop state (step S13), and the tension device 110 is further driven (step S14). ), The winding device 60 is driven (step S15). Note that a timer for controlling the winding amount of the polishing belt 20 is started at the drive start timing of the winding device 60 in step S15. Thereafter, the polishing belt winding operation start process is terminated and the process returns to the main flow.

  On the other hand, when the polishing belt replacement flag is “1” in step S12 and the polishing belt 20 needs to be replaced, a notification is made to prompt the employee to replace the polishing belt 20 (step S16). In the embodiment, a notification for urging the replacement of the polishing belt 20 is made by a blinking display of the display device 41 provided outside both ends of the game island stand 30. After that, when the replacement work of the polishing belt 20 is performed by an employee, and the position detection sensor 204 does not detect the end state of one roll of the polishing belt 20, the polishing belt replacement flag is set to “0” based on this. (Step S17), and the winding process of the polishing belt 20 is terminated.

  In the above-described processing for stopping the ball polishing and lifting device in step S11, as shown in FIG. 13, after closing the insertion shutter (not shown) for blocking the introduction of the pachinko balls to the introduction basket 7 (step S21), When 5 seconds have elapsed (step S22), the various drive motors of the ball polishing and lifting device 1 are stopped (step S23), and the process returns to the polishing belt winding operation start process. That is, in the ball polishing lifting device stop process, after the pachinko ball introduction to the ball polishing lifting device 1 is cut off, the ball polishing lifting device 1 is driven for 5 seconds, so that the inside of the ball polishing lifting device 1 It is designed to eliminate the pachinko balls.

  In the polishing belt winding amount control process in step S3, as shown in FIG. 14, first, whether or not the position detection sensor 204 detects the end state of one roll of the polishing belt 20, that is, one roll end detection. It is determined whether the part is ON (step S31). If the end of one roll is not detected in step S31, it is determined whether or not the elapsed time of the timer started in step S15 of the above-described polishing belt winding operation start process has passed a predetermined time (step S31). S32). The predetermined time is set to a time that is sufficiently long to wind up one surface of the polishing belt 20 (ball polishing surface) set in the ball polishing and lifting device 1. If the predetermined time has passed in step S32, an abnormality notification regarding time-over is performed (step S33), and then the polishing belt winding amount control process is terminated and the process returns to the main flow.

  On the other hand, if the predetermined time has not passed in step S32, it is determined whether or not the winding amount of the polishing belt 20 by the winding device 60 started in step S15 exceeds the predetermined winding amount (step S34). The predetermined winding amount is set to the length of the ball polishing surface of the polishing belt 20 attached to the ball polishing and lifting device 1 for each game island stand 30 and is set on the aforementioned “1” game island stand 30. In the ball polishing and lifting apparatus 1 having a total length of 254 cm, 227 cm, which is the length of the ball polishing surface of the polishing belt 20, is the predetermined winding amount. In step S34, if the winding amount of the polishing belt 20 does not exceed the predetermined winding amount, in other words, if the polishing belt 20 for one surface of the ball polishing is not wound, the process returns to step S31. Further, if the winding amount of the polishing belt 20 exceeds the predetermined winding amount in step S34, in other words, if the polishing belt 20 for one surface of the ball polishing is wound, the polishing belt winding amount control process is ended. To return to the main flow. In addition, the flow process of step S31-step S32-step S34 in the polishing belt winding amount control process constitutes a normal polishing belt movement control means according to the present invention.

  When the end of one roll is detected in step S31 described above, a polishing belt winding operation stop process similar to that in step S4 is executed (step S35). Note that the polishing belt winding operation stop processing in step S4 and step S35 will be described in detail later. Thereafter, the current winding amount A of the polishing belt 20 is calculated (step S36). Here, the winding amount A is calculated based on the rotation speed signal of the slip detection sensor 147 of the tension device 110. Specifically, each time the rotation speed signal is output from the slip detection sensor 147, the pressure roller 144 rotates once, and the 60 mm polishing belt 20 is wound by one rotation of the pressure roller 144. For this reason, the winding amount A has a value of “number of times of output of the rotation number signal” × “60 mm”. For example, when the number of output of the rotation number signal is “37”, the winding amount A is “222 cm”.

  Next, the winding ratio B of the polishing belt 20 is calculated from the winding amount A of the polishing belt 20 calculated in step S36 (step S37). Here, the winding ratio B is a value of “winding amount A” / “predetermined winding amount (= the length of one polished surface (the polished surface) of the polishing belt 20)” × “100”. . For example, when the winding amount A is “222 cm” in the ball polisher 1 having a predetermined winding amount of “227 cm”, the winding ratio B is “97.8%”.

  Next, the operation rank of the game island stand 30 on which the ball polishing and lifting device 1 is installed is calculated (step S38). Here, the operating rank of the game island stand 30 includes the operation amount of the game island stand 30 and the presence / absence of the ball return device 40 (described as “JC” in FIG. 15) (the ball return device on the game island stand 30). 40 is installed) and the cleanliness level is calculated with reference to the operation rank calculation table shown in FIG. Specifically, in the present embodiment, the amount of operation of the game island stand 30 is set to the total number of pachinko balls that have become dirty with the operation of the game island stand 30 on the day when the end state of one roll is detected, The total number of dirty pachinko balls is a value obtained by adding the total number of out balls from each gaming machine 31 arranged on the gaming island stand 30 and the total number of returned balls to the ball returning device 40. However, when the ball return device 40 is not installed on the game island stand 30, the total number of out balls is the total number of dirty pachinko balls, that is, the operation amount of the game island stand 30.

  In the embodiment, the total number of pachinko balls discharged from each gaming machine 31 arranged in the gaming island base 30 is actually calculated based on the counting signal from each out ball collection box 37, and the ball The total number of pachinko balls returned from the return device 40 is actually calculated based on the count signal from the ball return device 40, and the operating amount of the game island stand 30 is calculated based on these calculated values. Yes.

  Here, the reference value for determining the operation amount set in each item of the operation rank calculation table shown in FIG. First, the total number of out balls is approximately 25,000 per day for each gaming machine 31, and the average number of gaming machines 31 installed on one gaming island 31 is 36. Therefore, 900,000 (= 25000 × 36) pieces becomes the reference value of the total number of out balls. On the other hand, the total number of balls returned is approximately 9375 per day for each gaming machine 31, and the average number of balls returned per two game islands 30 is one. Since the apparatus 40 is installed, 655,000 (= 9375 × 36 × 2) pieces becomes the reference value of the total number of returned balls. Therefore, the reference value of the operation amount for setting the operation rank calculation table is 1575,000 (= 900,000 + 655,000).

  In the operation rank calculation table shown in FIG. 17 (A), the presence / absence of the ball return device 40 is determined for each of the cleanliness levels 1 to 3 based on the above-described reference value of the operation amount (1575,000). The operating amount value is set. The cleanliness levels 1 to 3 correspond to the “cleanliness level” values of the setting item display unit 58 displayed on the display screen of the second display mode of the management device 50 described above. That is, an input is made in the item “cleanliness level” of the setting item display unit 58 as a determination level on the game field side when determining whether or not to notify the replacement of the polishing belt 20 when one roll of the polishing belt 20 is finished. Based on the obtained value, it is determined which cleanliness level 1 to 3 in the operation rank calculation table is referred to. For example, in the game island stand 30 where the ball return device 40 is installed, a cleanness level 2 is set in the ball polishing and lifting device 1 of the game island stand 30 and the operation amount of the game island stand 30 is 1.26 million. In this case, the operation rank 4 is calculated from the operation rank calculation table of FIG.

  Next, the winding ratio B calculated in step S37 and the operating rank of the game island stand 30 calculated in step S38 are collated with the replacement display determination table shown in FIG. Is determined (step S39: determination means). In the replacement display determination table shown in FIG. 17B, the winding ratio B is set to “0-30%”, “31-50%”, “51-70%”, “71-90%”, “91-99%”. For each of the operation ranks 1 to 5, whether or not the replacement indication of the polishing belt 20 is necessary is set. In the figure, the necessity of replacement indication of the polishing belt 20 is indicated by “◯”, while the necessity of replacement indication of the polishing belt 20 is indicated by “X”. For example, when the winding ratio B calculated in step S37 is “97.8%” and the operating rank of the game island stand 30 calculated in step S38 is “4”, it is shown in FIG. With reference to the replacement display determination table, “O” is displayed, and it is determined that the replacement display of the polishing belt 20 is not necessary.

  Next, it is determined whether it is necessary to display the replacement of the polishing belt 20 based on the determination result of step S39 (step S40). When it is necessary to display the replacement of the polishing belt 20 in step S40, after notifying the employee to replace the polishing belt 20 by the blinking display of the display device 41 as in step S16 described above (step S41: Belt replacement notification means), the polishing belt winding amount control process is terminated, and the flow returns to the main flow. On the other hand, when it is not necessary to display the replacement of the polishing belt 20 in step S40, "1" is set to the polishing belt replacement flag (step S42: continuous use state storage means), and then the polishing belt replacement flag signal is output. Later (step S43), the polishing belt winding amount control process is terminated and the process returns to the main flow. In addition, with the output of the polishing belt replacement flag signal in step S43, the belt state display unit 54 provided on the display screen of the first display mode of the management device 50 displays one roll of the polishing belt 20 of the corresponding game island stand 30. A lighting display indicating that the belt is in use in the end state is performed, and the total number of polishing belts 20 used in the end state of one roll is displayed on the belt number display unit 56 (replacement total number notifying unit). In addition, the flow processing of each step shown in step S31 to FIG. 15 in the polishing belt winding amount control processing constitutes the special-time polishing belt movement control means according to the present invention.

  In the polishing belt winding operation stop process in step S4, as shown in FIG. 16, after stopping the stop device 160 (step S51), when 5 seconds have passed (step S52), the driving of the tension device 110 is stopped. (Step S53), the driving of the winding device 60 is stopped (Step S54), the polishing belt winding operation stop process is terminated, and the process returns to the main flow. That is, in the polishing belt winding operation stop processing, the stopping device 160 is stopped, and then the tensioning device 110 and the winding device 60 are driven for 5 seconds, so that the polishing belt 20 on the ball polishing surface is tightly ground. A process of setting in the lifting device 1 is performed.

  In the above-described embodiment, the cleanliness level of the polishing belt 20 is set and inputted in advance at the amusement hall side, and polishing is performed in the end state of one roll based on the operation rank calculated according to the cleanliness level. It is configured to determine whether or not to replace the belt 20, but not limited to this, without setting the cleanliness level, simply determine the operating rank based on the operating amount of the game island stand 30, It may be determined whether or not the polishing belt 20 is to be replaced when one roll is finished. In this case, the operation rank calculation table shown in FIG. 18 is used instead of the operation rank calculation table shown in FIG. In the operation rank calculation table of FIG. 18, the value of the operation amount according to the presence / absence of the ball return device 40 (denoted as “JC” in the figure) is set without dividing the items for each cleanliness level. Yes.

  Further, in the embodiment, the operating amount of the game island stand 30 is set to the total number of pachinko balls that are soiled with the operation of the game island stand 30 for the day when the end state of one roll is detected. The total number of balls is a value obtained by adding the total number of out balls from each gaming machine 31 arranged on the gaming island stand 30 and the total number of returned balls to the ball returning device 40, but is not necessarily limited to this configuration. Not what you want. For example, only one of the total number of out balls from each gaming machine 31 or the total number of returned balls to the ball return device 40 may be used as the operation amount (total number of dirty pachinko balls). In addition, the total number of pachinko balls that are lifted by the ball polishing and lifting device 1 on the day when the end state of one roll is detected may be used as an operating amount, and the ball polishing and lifting device 1 is not always driven. When the configuration is such that it is driven only when necessary, the operation amount may be calculated based on the drive time. Further, the total number of pachinko balls paid out from each gaming machine 31 arranged in the gaming island stand 30, the total number of rental balls from each ball lending machine (not shown) provided adjacent to each gaming machine 31, The operating amount may be calculated from other than the pachinko balls circulating in the game island stand 30, such as calculating the operating amount based on the numerical value obtained by adding.

  In the embodiment, the total number of pachinko balls discharged from each gaming machine 31 is calculated based on the count signal from each out-ball collection box 37, and the total number of pachinko balls returned from the ball return device 40. Is calculated based on the counting signal from the ball return device 40, and the amount of operation of the game island stand 30 is calculated based on these calculated values, but is not limited to this configuration. For example, a counter may be installed in the pachinko ball collection path in the game island stand 30, and the amount of operation may be calculated based on the ball count signal from the counter. Further, when calculating the operation amount, it is not always necessary to use an accurate count value. For example, each ball amount detection switch for detecting the upper limit and the lower limit of the amount of pachinko balls stored in the storage tank 39 of the game island stand 30 is provided, and the storage tank based on the number of ON / OFF times of the ball amount detection switch The approximate operating amount of the game island stand 30 may be calculated from the increase / decrease state of the pachinko balls in 39.

Also good.

  Further, assuming the operation status of the next day as a determination element for determining whether or not to notify the replacement of the used polishing belt 20 in which the end state of one roll is detected, polishing is performed based on input information corresponding to the assumption. You may make it determine whether the notification which urges | exchanges the belt 20 is performed. Input information according to this assumption includes, for example, whether or not there is an event for the next day (new stand replacement, etc.), weather for the next day (whether it is sunny, etc.), day of the next day (whether it is a weekend, holiday, etc.), Or the business hours of the next day etc. can be considered.

  As described above, according to the configuration of the present embodiment, when the one-roll end state of the polishing belt is detected by the one-roll end state detecting unit, the used one wound by the winding device up to the time point of detecting the one-roll end state. And the total number of pachinko balls soiled with the operation of the game island stand for the day when the end state of one roll is detected. Then, based on the calculated amount of winding of the used polishing belt and the calculated total number of dirty pachinko balls, it is determined whether or not to notify the user of replacement of the used polishing belt, When the determination to notify is made, the notification for prompting replacement of the polishing belt is performed. On the other hand, when the determination to notify replacement is not made, the notification for prompting replacement of the polishing belt is not performed. Accordingly, even when the end state of one roll of the polishing belt is detected by the one-roll end state detecting means, for example, the determination to replace and notify the polishing belt, for example, 90% of the polished surface of the polishing belt is an unused portion. When the operation is not performed, the use of the polishing belt can be permitted without notifying the exchange. Therefore, it is possible to eliminate the situation on the amusement hall side where it is necessary to replace the polishing belt according to the replacement notification even though most of the unused portion remains, and the roll-shaped polishing belt is effectively used to the end. Can be used.

  In addition, when it is determined that the notification for urging the replacement of the polishing belt is not performed, the state in which the polishing belt is continuously used in spite of the detection of the one-roll end state by the one-roll end state detecting unit. When the control of the polishing belt moving device drive control means is started for the polishing belt that has been stored and the continuous use state is stored, the replacement notification of the polishing belt is performed. As a result, when the polishing belt is used in a state where one roll is finished, the replacement notification can be immediately made when the polishing belt is used, and the replacement operation of the polishing belt can be performed smoothly. Further, according to this configuration, when there is a polishing belt in which the end state of one roll is detected along with the winding by the winding device and the replacement notification is made at the time of detection of the end state of the one roll, the polishing belt Therefore, it is possible to notify the replacement work in order without causing confusion to the employee.

  In addition, in a plurality of game islands installed in the game hall, the continuous use state of all the polishing belts that are continuously used despite the detection of the end state of one roll is stored, and the continuous use is stored. The total number of polishing belts whose states are stored is notified. As a result, the amusement hall side can grasp in advance the minimum number of polishing belts to be replaced at the end of the next business operation, so that the replacement work of the polishing belt can be performed more smoothly. Can do.

  In addition, the determination element includes a cleanliness level that can be set in advance on the game site side for determining whether or not to notify the replacement of the polishing belt in which the end state of one roll is detected. This makes it possible to easily change the determination criterion for the notification of replacement of the polishing belt according to the needs of the game hall. For example, amusement islands with a large number of target models for the event of the next day are expected to operate at high levels. For such amusement islands, operating conditions such as increasing judgment criteria to emphasize cleanliness It is possible to change the judgment criterion according to the situation.

  In addition, based on the sum of the total number of pachinko balls discharged from a plurality of gaming machines lined up on the game island stand and the total number of pachinko balls returned from the ball return device, the operation of the game island stand Accordingly, the total number of dirty pachinko balls is calculated, and the replacement notification of the polishing belt in which the end state of one roll is detected is determined from the total number of dirty pachinko balls. This makes it possible to calculate the total number of pachinko balls that have become dirty with the operation of Ogishimadai from a more accurate value, so that the dirt status of the polishing belt can be ascertained more reliably, and as a result, more accurate. In addition, it is possible to determine whether or not the polishing belt has been replaced when the end state of one roll is detected.

  Further, the use is such that the rotation speed of the pressure roller provided in the tensioning device and pressing the polishing belt is detected by a slip detection sensor, and the winding device winds up based on the rotation speed of the pressure roller detected by the slip detection sensor. A winding amount of the used polishing belt is calculated, and a notification of replacement of the polishing belt in which the end state of one roll is detected is determined from the winding amount of the used polishing belt. As a result, it is possible to more accurately grasp the winding amount of the used polishing belt wound up by the winding device, and as a result, it is possible to more accurately determine the notification of replacement of the polishing belt when the end state of one roll is detected. can do.

  In the embodiment, the stop process of the polishing / lifting apparatus and the movement control of the polishing belt moving apparatus are performed by a series of processes. However, each process may be performed separately. In such a case, the timing at which the polishing belt replacement display in step S16 of FIG.
