Description

  The present invention relates to a transfer device for transferring a game ball flowing into a transfer surface of a main body by a transfer means and discharging the game ball from the main body.

  A game machine installation island where a plurality of pachinko machines, etc. are arranged is generally equipped with a lifting device (transfer device) that lifts game balls discharged from the pachinko game machine etc. to the upper part of the game machine installation island. In particular, a belt-shaped polishing cloth (cleaning member) is stretched in the vertical direction so as to face the game ball being lifted, and the game ball is lifted while being polished (cleaned). .

  In this type of polishing cloth, an upper part and a lower part are held by a pair of upper and lower clamping devices provided on the outer surface of an urging plate for urging the polishing cloth toward the game ball. When the polishing surface is contaminated, the holding state by the clamp device is released, and a new polishing surface can be arranged by pulling out the polishing cloth from the upper part or the lower part. Such an operation of pulling out the polishing cloth must be performed frequently, for example, every business day, in an environment where the polishing cloth such as a lifting device installed on a gaming machine installation island where the operating rate of the gaming machine is high is easily contaminated. It may not be possible.

  As this type of clamping device, for example, an abrasive cloth is inserted between a resistor and a pressing member arranged to face the resistor, and the pressing member is biased toward the resistor by a handle operation. The tension is applied to the polishing cloth by holding the upper part or the lower part of the polishing cloth and urging the movable clamp provided with the resistor and the pressing member in the direction of applying the tension of the polishing cloth by the spring. There is something like that (see, for example, Patent Document 1).

  Similarly, the friction roller supported in a movable manner by a guide slot provided in the casing biased in the direction of applying the tension of the polishing cloth can be rotated only in the pulling direction by the locking claw. There is a mechanism in which a ratchet mechanism for locking is employed, and the polishing cloth is sandwiched between the outer periphery of the friction roller moved by the guide means by the operation of pulling up the polishing cloth and the housing (for example, see Patent Document 2). ).

Japanese Patent Laying-Open No. 2005-21192 (page 11, FIG. 4) JP 2007-260221 A (page 5-6, FIG. 6)

  However, in the lifting device described in Patent Document 1, when performing a work of pulling out a new polished surface, the holding member is released by separating the pressing member from the resistor by a handle operation. When holding the polishing cloth again after pulling out the polishing cloth, it is necessary to sandwich the polishing cloth by operating the handle while maintaining the state where the movable clamp is pushed upward against the biasing force of the spring. There was a problem that workability was bad.

  In the lifting device described in Patent Document 2, when the polishing cloth is pulled upward, the casing itself is pulled upward against the urging force of the spring, and the guide roller has a guide slot. Since the polishing cloth is moved to the top and the polishing cloth is sandwiched between the casing and the reverse rotation of the guide roller is regulated by the locking claw, the tensioning state of the polishing cloth is maintained. When the cloth is pulled up, the spring biasing force is applied, so it is difficult to pull up the cloth. Since the rotating roller cannot be returned to the lowest position of the guide slot unless the holding state is released, there is a problem that the operation is complicated.

  The present invention has been made paying attention to such problems, and an object of the present invention is to provide a transfer device that can easily perform a tensioning operation of a cleaning member.

In order to solve the above-described problem, a transfer device according to claim 1 of the present invention provides:
The game balls (pachinko balls) flowing into the transfer surface of the main body (100) (the surface facing the pachinko balls (inner surface) of the passage plate 114) are transferred to the transfer means (conveying belt 103, upper roller 101, lower roller 102, lifting motor). 80) and a transfer device (lifting device 25) for transferring from the main body and discharging from the main body,

It is provided so that it can be pulled out in the direction of the side folded portion. In this state, when the cleaning member is pulled out in the direction of the downstream folded portion, the cleaning member folded in the upstream folded portion direction at the fixed portion is pulled out in the downstream folded portion direction using the fixed portion as a fulcrum. Since the second holding portion is returned to the retracted position against the urging force of the urging means by the member, the clamping state can be easily released simply by pulling out the cleaning member. Further, when the cleaning member that has been pulled out is released, the second holding portion that is urged toward the holding position by the urging means presses the cleaning member toward the upstream folded portion and presses the first holding portion.

A round path member which is disposed below the bar 104 and the lower roller 102 and is formed in a substantially arc shape along the outer peripheral surface of the lower roller 102 in order to press the pachinko ball against the conveying belt 103 at the position of the lower roller And a ball introduction passage serving as a ball introduction member which is disposed opposite to the opposite side of the round passage cover 105 below the lower roller 102 and guides a pachinko ball to the round passage cover 105. The cover 106 is mainly composed of.

  The upper passage cover 118, the linear passage cover 104, the rounded passage cover 105, and the ball introduction passage cover 106 that are arranged to face the outer surface of the conveyance belt 103 are circulated by the rotation of the upper roller 101 and the lower roller 102. A passage member for pressing and feeding the pachinko ball to the belt 103 is configured.

  The lower roller 102 is a driving roller that is driven by a lifting motor 80 (see FIG. 4) provided at the lower part of the main body, and the upper roller 101 is a driven roller, and is in the direction of the arrow (clockwise) in FIG. It is designed to rotate. Further, as shown in FIG. 5, above the lower roller 102, a tension roller 108 capable of adjusting the tension of the conveyor belt 103 and driven rollers 107 and 109 disposed above and below the tension roller 108 are rotatably supported. The conveyor belt 103 is stretched so as to meander between the driven rollers 107 and 109 and the tension roller 108. The detailed structures of the upper roller 101, the lower roller 102, the driven rollers 107 and 109, and the tension roller 108 will be described later.

  The linear passage cover 104 is configured by a plate-like member extending in the vertical direction, and is pivotally attached to one side of the rear surface of the main body 100 so that the rear surface of the main body 100 can be opened and closed as shown in FIG. The upper, middle and lower locking members 111a to 111c pivotally attached to the main body 100 are locked to the upper, middle and lower locking pins 112a to 112c protruding from the other side. It can be locked at the closed position.

  As shown in FIG. 6 in particular, the inner surface of the linear passage cover 104 has a plurality of rows of substantially hemispherical concave grooves 113 for forming a linear passage 115 extending in the vertical direction (in this embodiment, 7) The vertically long passage plates 114 formed side by side are arranged in a state of being biased toward the conveying belt 103 via a plurality of coil springs 117, and the linear passage cover 104 is placed in the closed position. When positioned, the plurality of concave grooves 113 are arranged opposite to the outer surface of the conveyor belt 103, and a plurality of rows of linear passages 115 extending in the vertical direction are formed.

  The pachinko spheres P in the linear passages 115 guided by the concave grooves 113 are pressed against the conveying belt 103 by the passage plate 114, and the inside of the passage is directed upward by the movement of the conveying belt 103. It is moved and lifted. That is, the surface (inner surface) facing the pachinko ball in the passage plate 114 constitutes the transfer surface of the game ball in the present invention.

  In addition, a cleaning cloth 116 as a cleaning member for cleaning pachinko balls transported in the passages is laid on the inner surface side of the passage plate 114, so that the pachinko board is pachinko by the passage plate 114 via the cleaning cloth 116. When the balls P are pressed toward the transport belt 103, the pachinko balls P are transferred while being in sliding contact (contact) with the cleaning cloth 116 due to the movement of the transport belt 103. It has come to be. That is, the lifting device 25 in the present embodiment is a lifting and cleaning device that lifts the pachinko ball P while cleaning it.

  The cleaning cloth 116 has a belt shape and is stretched in the vertical direction (from the upstream side to the downstream side in the pachinko ball transfer direction) along the inner surface of the passage plate 114 of the linear passage cover 104. An upper clamp provided on the outer surface of the linear passage cover 104 after the upper side of the stretched cleaning cloth 116 is folded outward and downward at the upper end portion (downstream folding portion) of the linear passage cover 104. It is held in a state of being inserted into the device 300 (see FIG. 5), and is laid along the outer surface of the linear passage cover 104. Further, the lower side of the cleaning cloth 116 is folded outward and upward at the lower end portion (upstream folded portion) of the linear passage cover 104, and then the lower clamp device 400 provided at the lower outer surface of the linear passage cover 104. (See FIG. 5) and held along the outer surface of the linear passage cover 104.

  In this way, the cleaning cloth 116 is folded outward at the upper and lower ends of the linear passage cover 104, and the upper part pulled out along the outer surface of the linear passage cover 104 is removed by the upper clamp device 300. Since it needs to be held by the lower clamp device 400, at least the vertical width dimension of the linear passage cover 104, that is, the longitudinal width of the cleaning portion in which the cleaning cloth 116 is laid in the linear passage 115 so as to come into contact with the pachinko balls. When the sliding contact surface with the pachinko ball is soiled, the holding state by the upper clamp device 300 and the lower clamp device 400 is released, and the cleaning portion of the linear passage 115 is configured. The used part of the cleaning cloth 116 disposed in the upper part is pulled out from the upper part or the lower part, and the unused part is newly disposed in the cleaning part of the linear passage 115. It has been cut way. The detailed structure of the upper clamp device 300 and the lower clamp device 400 will be described later.

  As shown in FIG. 5, the linear passage 115 formed by the linear passage cover 104 is formed on the front side of the main body 100, that is, on the ascending side of the conveyor belt 103 from the rotation shaft 101a to the rotation shaft 102a. ing. Then, the pachinko ball P transferred upward in the linear passage 115 is folded back to the front side (right side in FIG. 5) by an arc-shaped upper passage 119 formed by an upper passage cover 118 provided at the upper portion of the main body 100. After that, it flows down the discharge cover 120 connected to the upper passage cover 118, is discharged from the discharge port 38 formed in the discharge cover 120, and is stored in the upper tank 3. .

  Below the straight passage 115, that is, on the upstream side, a round-shaped passage 121 formed by the round-shaped passage cover 105 described above is formed, and flows from a spherical inlet 122 provided at the lower front side of the main body 100. The pachinko balls to be guided are guided toward the upper linear passage 115.

  A pachinko sphere P flowing down the sphere introduction passage 123 formed by the sphere introduction passage cover 106 provided at the sphere inlet 122 on the upstream side of the round passage cover 105 is introduced into the round passage 121. It has become.

  At the upstream end of the ball introduction passage cover 106, as shown in FIG. 7, there is provided a junction 124 where the pachinko balls that have flowed down the relay rods 24L and 24R described above merge. The junction portion 124 includes a junction plate 125 disposed at a lower position between the end portions of the left and right relay rods 24L and 24R, and a snorkel rail 126 disposed below the junction plate 125. In addition, the code | symbol 127 in FIG. 7 is a partition plate arrange | positioned between the edge parts of right and left relay rod 24L, 24R, and it is prevented that a flow-down is restrict | limited by the pachinko ball which flows out from the opposite cage | basket. It has become so.

  The junction plate 125 is formed with a plurality of large-diameter holes 125a having a diameter of about 20 mm for dropping pachinko balls flowing out from the ends of the relay rods 24L and 24R. The fallen pachinko ball is dropped from the large-diameter hole 125a, so that, for example, a large foreign object such as a prepaid card used for lending the pachinko ball is captured, and entry into the lifting device 25 is prevented. ing.

  The pachinko balls that have fallen from the large-diameter hole 125a flow down the snocorail 126 (see FIG. 8) disposed so as to be inclined downward toward the ball introduction passage 123, and flow into the ball introduction passage 123. It has become. Then, when falling on the snorkel rail 126 and flowing down, the foreign matter that has fallen through the large-diameter hole 125a falls into the space 128 provided below from the gap of the snorkel rail 126 and is removed. It has become.

  Note that the diameter of the large-diameter hole 125a is set to a size that allows an appropriate amount of pachinko balls flowing into the merge portion 124 to be dropped on the snorkel rail 126 below the large amount without falling. In this way, by suppressing the outflow amount of the pachinko sphere onto the snorkel rail 126, a large amount of the pachinko sphere flows into and fills the snocorail 126 and the sphere introduction passage 123 on the downstream side thereof, thereby the inflow port 112. A high ball pressure is applied to the lower roller 102 and the conveyor belt 103 in the vicinity, and an excessive load is prevented from being applied to a feed motor (not shown) that drives the lower roller 102 to rotate.

  The lifting device 25 configured as described above flows down the relay rods 24L and 24R, is discharged to the joining portion 124, joins, and is guided by the snorkel rail 126 and the ball introduction passage 123 and passes through the ball inlet 122. The pachinko balls that have flowed into the interior are moved through the rounded passage 121, the straight passage 115, and the upper passage 119 by the movement of the conveyor belt 103, and are lifted upward while being cleaned by the cleaning cloth 116, and It can discharge | emit from the discharge port 38 provided in this.

  Next, detailed structures of the rounded passage cover 105, the ball introduction passage cover 106, and the snocorail 126 will be described with reference to FIGS.

  First, as shown in FIG. 8 and FIG. 9, the snowboard rail 126 is disposed between the eight side wall rails 130 that form the side surface of the flow path of the pachinko sphere and the side wall rails 130. The seven bottom wall rails 131 constituting the bottom surface of the passage and the base body 132 that integrates the side wall rail 130 and the bottom wall rail 131 are formed, and seven rows of downflow passages 135 are formed. A plurality of openings 133 are formed on the side of each bottom wall rail 131, and foreign substances fall below the base body 132 through these openings 133.

  The ball introduction passage cover 106 is formed of a synthetic resin material such as polycarbonate, and is disposed between eight side plates 140 that form the side surfaces of the downflow passages of the pachinko spheres and the side plates 140. 7 side plates 141 constituting the bottom surface, and the side plates 140 standing on the floor surface are integrated with each other by the bottom plate 141, and seven rows of ball introduction passages 123 are formed between the side plates 140. Has been.

  In addition, on the upstream side of each bottom plate 141, slits 145 for dropping foreign substances such as nails that have moved together with the pachinko balls are formed so as to extend in the longitudinal direction. The width dimension of the slit 145 is a width dimension that allows a head such as a screw to pass through and that the pachinko ball that passes through the slit 145 cannot fall. It rolls in a state where the two points are in contact with both side edges of the slit 145, and the end on the lower side of the slope is formed so as to be gradually tapered toward the moving direction of the pachinko ball. Yes.

  Further, by forming the slit 145 at the center in the width direction between the side plates 140 and 140 in the bottom plate 141, foreign substances such as nails and the pachinko balls moving in the ball introduction passage 123 are located in the center in the width direction of the ball introduction passage 123. It is possible to prevent the pressing plate 151 from being damaged by moving the position and coming into contact with the pressing plate 151 disposed at the center position in the width direction between the guide plates 150 and 150 in the rounded path cover 105 described later.

  The end face of each side plate 140 facing the lower roller 102 is cut out in an arc shape centering on the rotating shaft 102a of the lower roller 102, and is close to the outer surface of the conveyor belt 103 as shown in FIG. It can be arranged. More specifically, the end surface of each side plate 140 facing the lower roller 102 is formed by a curved surface corresponding to about ¼ of the circumference of the lower roller 102. In this way, the sphere introduction passage cover 106 is erected on the floor surface, and has a plurality of side plates 140 arranged in parallel at equal intervals in the passage width direction, and a bottom plate 141 disposed between the side plates 140, 140. , And is formed in a cubic shape in which a portion facing the lower roller 102 is recessed in a curved shape.

  Each bottom plate 141 is composed of a strip-like plate material extending in the longitudinal direction of the sphere introduction passage 123, and is inclined downward from the end portion on the snoco rail 126 side toward the end portion on the round-shaped passage cover 105 side. The pachinko ball from the snowboard rail 126 is guided to the rounded passage 121 by flowing down.

  Further, from the lower ends of the side plates 140, 140 at both ends in the passage width direction, a fixing piece 142 for fixing the sphere introduction passage cover 106 to the base plate 110 is continuously provided outwardly and formed on the fixing piece 142. A fixing screw (not shown) is inserted into the mounting hole 143 and is screwed into the base plate 110 so that it can be fixed to the base plate 110.

  The sphere introduction passage cover 106 configured in this way is configured such that the lower ends of the left and right side plates 140 are installed on the base plate 110, and as shown in FIG. A downstream end (front end) is inserted into the space between the lower rear surface side of the lower roller 102 and the base plate 110, and the opposite end surface of each side plate 140 facing the lower roller 102 is disposed close to the conveying belt 103. Is done.

  The rounded passage cover 105 is spaced apart at intervals L2, L2 ′ wider than the diameter L1 of the pachinko ball P, forms the side surface of the rounded passage 121, and guides the game ball along the rotation direction of the lower roller 102 The guide plate 150 as a guide member to be moved and the guide plate 150 and 150 adjacent to each other are arranged with a gap (S1) narrower than the diameter (L1) of the pachinko sphere, and are conveyed over the lower roller 102 And a pressing plate 151 as a pressing member having a pressing surface 151 a as a pressing surface portion for pressing a pachinko ball against the belt 103. The guide plate 150 is made of a synthetic resin material such as polycarbonate (for example, Rockwell hardness M scale 65 to 78, R scale 121 to 127) having excellent heat resistance and wear resistance and higher hardness than the pressing plate 151. These guide plates 150 are integrated with each other by an upstream piece 152, a downstream piece 153, a downstream lower piece 154, and a part of the intermediate guide piece 155 to constitute a main body.

  Since parts other than the upstream piece 152, the downstream piece 153, the downstream lower piece 154, and the intermediate guide piece 155 are open, foreign matter is present in the gap S 1 between the guide plate 150 and the pressing plate 151. It is easier to be pushed into the back side than the pressing surface 151 a of the pressing plate 151.

  Further, in this embodiment, the guide plate 150 and the pressing plate 151 are configured by a plate material that has a flat plate portion extending in the vertical direction as a whole, but the present invention is not limited to this, for example, Only a part of the guide plate 150 in the vicinity of the end surface facing the lower roller 102, the vicinity of the pressing surface 151a of the pressing plate 151, or the like may be configured by a member configured by a flat plate portion.

  Each guide plate 150 is formed in a substantially triangular shape when viewed from the side, and is erected vertically on the base plate 110. The end surface facing the lower roller 102 is cut out in an arc shape centering on the rotating shaft 102a of the lower roller 102 so that it can be disposed close to the outer surface of the conveyor belt 103 as shown in FIG. It has become. More specifically, the end face of each guide plate 150 facing the lower roller 102 is formed by a curved surface corresponding to about ¼ of the circumference of the lower roller 102. In this way, the rounded passage cover 105 is erected on the floor surface, and a plurality of guide plates 150 arranged in parallel in the passage width direction at equal intervals, and a pressure disposed between the guide plates 150 and 150. The plate 151 is formed in a cubic shape in which a portion facing the lower roller 102 is recessed in a curved shape.

  Further, from the lower ends of the guide plates 150 and 150 at both ends in the passage width direction, attachment pieces 156 for attaching the rounded passage cover 105 to the base plate 110 are continuously connected outwardly, and formed on the attachment pieces 156. The mounting screw 158 (see FIG. 13A) is inserted into the mounting hole 157 and screwed into the base plate 110, so that it can be detachably attached to the base plate 110.

  On the upstream side of the lower end surface 150 a of each guide plate 150 (the lower surface on the sphere introduction passage cover 106 side), an inclined surface 150 b that is inclined upward toward the upstream end, that is, the sphere introduction passage cover 106 is formed. As will be described later, when the rounded passage cover 105 is removed from the mounting position, the upstream end can be tilted downward.

  Further, as shown in FIG. 10A, the upstream side of each guide plate 150 is formed with a thin portion 159 having a smaller thickness than the downstream side, whereby the upstream side width of the rounded passage 121 is formed. The dimension L2 ′ is wider than the downstream width dimension L2. Specifically, the downstream width L2 and the upstream width L2 'of the rounded passage 121 are larger than the diameter L1 of the pachinko sphere P (L1 <L2 <L2'). As a result, the receiving port for the pachinko sphere that has flowed in from the ball introduction passage 123 is widened, so that it is difficult for a ball to be clogged or the like at the joint portion, and foreign matter is easily dropped from a deformation allowable space portion 164 described later.

  Between the opposing surfaces of the upstream piece 152 and the downstream piece 153 and between the guide plates 150 of the intermediate guide piece 155 to be described later, the pressing plates 151 are directed in the vertical direction for inserting and removing the vertical plates (see FIG. 8). Guide grooves 152a, 153a, and 155a are formed, and the pressing plates 151 are sandwiched. The pressing plate 151 guided by these guide grooves 152a, 153a, 155a is formed by the upper end of the downstream lower piece 154 and the lower end of the guide groove 155a formed in the intermediate guide piece 155, as shown in FIG. It is received from below and positioned.

  From both side surfaces of the downstream end (upper end) of each guide plate 150, a horizontal guide piece 160 extending in the horizontal direction continuously provided at the upper end of the downstream piece 153 is projected toward the passage, From the front ends of these horizontal guide pieces 160, arcuate guide pieces 161 along the arcuate end surface of the guide plate 150 are provided continuously toward the upstream side (downward). Further, on the upstream side of the arcuate guide piece 161, an arcuate guide piece 162 having the same curvature as that of the arcuate guide piece 161 is projected from the side surface of each guide plate 150 into the passage. From the lower surface of the upstream end of the piece 162, the above-described intermediate guide piece 155 is suspended downward. The opposing end surfaces of the horizontal guide piece 160, the arc-shaped guide pieces 161 and 162, and the intermediate guide piece 155 are separated from each other by the same size as the thickness of the pressing plate 151 so that the pressing plate 151 can be inserted between these opposing end surfaces. The inserted pressure plate 151 is sandwiched and guided from the left and right sides.

  As described above, the intermediate guide pieces 155 are separated from each other downward from the lower surfaces of the upstream end portions of the arcuate guide pieces 162 and 162 projecting from the opposing surfaces of the adjacent guide plates 150 and 150, respectively. The guide grooves 155a described above are formed as bottomed guide grooves extending in the vertical direction, and the guide plates 150 and 150 adjacent to each other in the lower portion. They are linked together.

  The upper surfaces of the arcuate guide pieces 161 and 162 are arranged at a position slightly lower than the end surface of the pressing plate 151, that is, the bottom surface of the rounded passage 121, and do not come into contact with the pachinko balls P passing therethrough. By sandwiching the side surface of the pressing plate 151 near the pressing surface 151a from the left and right sides in the width direction, elastic deformation in the width direction of the passage is prevented.

  The upstream end of the arcuate guide piece 161 and the downstream end of the arcuate guide piece 162 are spaced apart by a predetermined distance to form a deformation allowing space 163, and the arcuate guide piece 162 has The upstream end portion and the upstream piece 152 are spaced apart by a predetermined distance to form a deformation allowing space 164. That is, the pressing surface 151a of the pressing plate 151 to be described later can be easily elastically deformed at two locations of these deformation permissible space portions 163 and 164.

  Each guide plate 150 is formed with two through holes 166a and 166b through which two through pins 165a and 165b for holding a later-described pressing plate 151 are inserted, and the through pins 165a and 165b are respectively provided. The R-shaped passage 121 can be inserted from either side of the width direction.

  Thus, the guide plate 150 and the pressing plate 151 have flat plate portions extending in the vertical direction, and by inserting the insertion pins 165a and 165b through the through holes 166a and 166b formed in these flat plate portions, Since each pressing plate 151 can be fixed to a main body portion in which a plurality of guide plates 150 are integrated, the pressing plate 151 can be easily assembled to the guide plate 150.

  In addition, an insertion piece 167 that is inserted into the lower space of the sphere introduction passage cover 106 protrudes from the surface of the upstream piece 152 that faces the sphere introduction passage cover 106, so that the upstream end is introduced into the sphere. It is locked to the passage cover 106 to prevent the floating.

  As shown in FIG. 8, the pressing plate 151 is in contact (rolling or sliding) with the end surface facing the lower roller 102, that is, the bottom surface of the rounded passage 121, that is, the pachinko ball. A plate-like hard member having a pressing surface 151a that forms a pressing surface portion that presses toward the conveyor belt 103 is formed in a substantially L shape in a side view formed by being cut out in an arc shape around the rotation shaft 102a of the lower roller 102. It is composed of a urethane resin material. As this hard urethane resin material, one having a rubber hardness of 90 in JIS standard is used, but this rubber hardness can press the pachinko ball P against the conveyor belt 103, and a load due to foreign matter is added as will be described later. As long as the hardness can be elastically deformed, the numerical range may be, for example, HS 60-100.

  The downstream end (upper end) of each pressing plate 151 is formed with a substantially U-shaped cutout groove 168aa opening upward, whereby the downstream end of the pressing surface 151a is elastically deformed outward. Therefore, the pressure applied to the pachinko ball is relieved at the downstream end of the rounded passage 121, that is, in the vicinity of the junction with the linear passage 115.

  Further, a substantially U-shaped notch groove 168b opened in a side view is formed at the upstream end (lower end) of each pressing plate 151, whereby the upstream end of the pressing surface 151a faces downward. Since it is easily elastically deformed, the pressure applied to the pachinko ball is released at the upstream end of the rounded passage 121, that is, in the vicinity of the junction with the flow-down passage 135.

  Each pressing plate 151 is aligned with the axial center of the through holes 166a and 166b formed in each guide plate 150 in a state where the pressing plate 151 is disposed at a fixed position between the respective guide plates 150. Two through-holes 169a and 169b through which 165a and 165b are inserted are formed, and the through-pins 165a and 165b are inserted so that a fixed position (see FIG. 9) provided between the guide plates 150 is provided. Deviations upward are regulated.

  The rounded path cover 105 configured in this way is configured such that the lower ends of the left and right guide plates 150 are installed on the base plate 110, and as shown in FIG. The upstream end portion (rear end portion) is inserted into the space between the lower front surface side of the lower roller 102 and the base plate 110, and the end surface of each guide plate 150 facing the lower roller 102 is brought close to the conveying belt 103. Arranged in a state.

  Next, the operation of the rounded passage cover 105 configured as described above will be described with reference to the drawings.

  First, as shown in FIG. 7, the rounded path cover 105 configured as described above is disposed so as to face the lower front side of the lower roller 102, so that the upstream end of the rounded path 121 A pachinko ball flowing down from the sphere introduction passage 123 is connected to the downstream end of the sphere introduction passage 123 arranged to face the lower rear surface side of the lower roller 102, and the outer surface of the conveyor belt 103 at the position of the lower roller 102 And the guide plates 150 and 150 and the pressing surface 151a of the pressing plate 151 enter the rounded path 121 surrounded by the pressing plate 151a. The pachinko ball P that has entered the rounded passage 121 is pressed toward the rotating conveyor belt 103 by the pressing surface 151a of the pressing plate 151, so that the movement of the conveyor belt 103 causes the arrow direction in FIG. From the position immediately below the lowermost end of the lower roller 102, the lower roller 102 is transferred upward along the outer periphery of the lower roller 102 toward the front side.

  At this time, since the pressing plate 151 is made of a hard urethane resin material, the pachinko ball P can be elastically biased toward the conveying belt 103 by the pressing surface 151a which is the end surface of the pressing plate 151. 151 is transported to the pachinko ball P without being provided so as to bias the guide plate 150 against the transport belt 103 or to bias the rounded path cover 105 itself toward the transport belt 103. Since an urging force in the direction of the belt 103 can be appropriately applied, the pachinko ball can be reliably pressed against the conveying belt 103 and transferred.

  Here, for example, as shown in FIG. 12, a description will be given of the case where the screw B, which is a foreign object, enters the rounded passage 121 together with the pachinko ball. The screw that is pushed by the pachinko ball and enters the rounded passage 121. Even if a part of B (for example, the head) is larger than the gap S1 formed between the opposing surfaces of the guide plate 150 and the pressing plate 151, the pressing force from the conveyor belt 103 always acts on the screw B. Therefore, when reaching the deformation allowable space 164, the screw B is forcibly pushed between the pressing plate 151 and one of the left and right guide plates 150 by the pressing force of the conveying belt 103, and the pressing is thereby performed. The pressing plate 151 and one guide plate 150 are elastically deformed in the width direction by the pressing surface 151a of the plate 151 and its vicinity, that is, at least a part of the pressing surface portion. Bis B writes fits between the gap S1 is pushed open pressing plate 151 and the guide plate 150.

  Thus, the gaps S1 and S1 are formed between the left and right guide plates 150 and 150 adjacent to the pressing plate 151, and the pressing plate 151 is made of a hard urethane resin material that can be elastically deformed. Thus, the pressing surface 151a of the pressing plate 151 constituting the pressing surface portion of the rounded passage 121 and the vicinity thereof can be deformed in the width direction of the passage, that is, elastically deformable between the adjacent guide members 150 and 150. Therefore, when the screw B passes through the deformation permissible space 164 or the deformation permissible space 163 on the downstream side, the space between the pressing plate 151 and one guide plate 150 is expanded by the screw B. It is easy to fit between them. That is, since the gaps S1 and S1 are formed on both sides of the pressure plate 151 in the passage width direction, the pressure plate 151 is allowed to be spread toward one of the guide plates 150. Since the gap S1 on the side where the screw B is fitted with the boundary 151 is pushed wide in the passage width direction and the other gap S1 is narrowed in the passage width direction, the gap between the opposing surfaces of the guide plate 150 and the pressing plate 151 is reduced. Even when a foreign matter such as screw B having a portion larger than the gap S1 formed in the case enters, the foreign matter is effectively prevented from being transferred together with the pachinko sphere P.

  Note that the upstream deformation allowable space 164 is the first part that presses the pachinko ball that has flowed into the rounded passage 121 toward the conveyor belt 103, so that foreign matter is easily pushed into the gap S1, and the downstream side In the deformation allowable space 163, since the upward movement of the pachinko sphere is started in the rounded passage 121, the force that presses the pachinko sphere toward the transport belt 103 is high, so the foreign matter is in the gap S1. It is easy to be pushed into.

  Further, since the pressing plate 151 is constituted by an elastic deformation member, after the force B is forcibly deformed by the screw B, the elastic restoring force works, so that the screw B that has been fitted in the pressing plate 151 and the guide By being sandwiched between the plate 150 and being difficult to come off, even if it is pushed by a subsequent pachinko ball, it is difficult to be lifted together with the subsequent pachinko ball. Therefore, since foreign matter can be retained in the rounded passage 121, it is possible to prevent damage to the conveyor belt 103, supply of pachinko balls to the pachinko machine 2, and troubles in pachinko ball circulation in the game island platform. Is done.

  Further, as compared with the case where the pressing plate 151 is made of a polycarbonate resin material or the like like the guide plate 150, the friction coefficient of the pressing surface 151a of the pressing plate 151 and the side surface in the vicinity thereof is high, and toward the gap S1. The pushed-in foreign matter is more easily caught.

  Next, the state of removal of the rounded path cover 105 when a ball clogging occurs in the rounded path 121 as described above or when performing regular maintenance work will be described.

  First, as described above, when a ball clogging occurs in any of the rounded passages 121 in the plurality of rows, the linear passage cover 104 of the main body 100 is first opened, and the vertical direction attached to the inner surface of the cleaning cloth 116 Check for streak-like dirt (not shown). Since these streak stains are generated corresponding to the respective linear passages 115, when the cleaning is performed normally, seven rows of streak stains are generated corresponding to the seven passages. However, for example, as described above, when a foreign substance is fitted in the rounded passage 121 to cause clogging of a ball, only the streak-like dirt in that row becomes thinner than the others, and this causes clogging of the ball. I can recognize that.

  When the rounded path cover 105 is removed from the attachment position, the left and right attachment screws 158 are first removed as shown in FIG. Then, as shown in FIG. 13 (b), with the upstream side of the rounded passage cover 105 slightly tilted downward (in the direction of the white arrow in FIG. 13 (b)), the upper surface of the base plate 110 is on the front side ( In FIG. 13 (b), it may be pulled out by sliding in the direction of the two-dot chain line arrow, the direction of the axis of the lower roller 102 (the direction intersecting the longitudinal direction of the rotating shaft 102a).

  As described above, even if the lower roller 102 is disposed so as to face the lower side, the base plate 110 can be simply pulled out by sliding the upper surface of the base plate 110 toward the front side without removing the ball introduction passage cover 106. It can be removed from the plate 110. At this time, the inclined surface 150b is formed on the upstream side (the sphere introduction passage cover 105 side) of the lower end surface 150a of the guide plate 150, so that the rounded passage cover 105 can be inclined. The guide plate 150 can be smoothly pulled out without causing the guide belt 150 to interfere with the conveyor belt 103 even in a state where the guide plate 150 remains in the channel 121.

  As described above, in the lifting device 25 according to the embodiment of the present invention, a part of a foreign matter such as a nail or a bolt that has entered the rounded passage 121 is between the guide plate 150 and the pressing plate 151. Even when the gap S1 is larger than the gap S1, the pressing surface 151a constituting the pressing surface portion of the pressing plate 151 and its vicinity are elastically deformed, so that foreign matter can easily fit into the gap S1 between the guide plate 150 and the pressing plate 151. In addition, the foreign matter fitted in the gap S1 is sandwiched between the guide plate 150 and the pressing plate 151 by the elastic restoring force of the pressing plate 151, and is difficult to come out. It becomes difficult to be lifted with the following ball. Therefore, foreign matters can be retained in the rounded passage 121, so that it is possible to prevent the conveyance belt 103 from being damaged and obstructing the replenishment of the pachinko balls P to the pachinko machine 2.

  Further, in this embodiment, the pressing surface 151 a of the pressing plate 151 is provided so as to be partially deformable only in the deformation-permitting space portions 163 and 164 in the longitudinal direction of the rounded passage 121, thereby excessive deformation of the pressing plate 151. However, it may be provided so as to be deformable over the entire length of the rounded passage 121 according to the hardness of the pressing plate 151 or the like.

  In particular, in the ball introduction passage 123 for guiding the pachinko sphere to the round-shaped passage 121, unlike the snowboard rail 126, a foreign substance cannot be dropped, and the bottom surface of the passage is constituted by the bottom plate 141, so By feeding the foreign matter into the cylindrical passage 121, it is possible to prevent the foreign matter from being fitted into the ball introduction passage 123 in the ball introduction passage cover 106 fixed to the base plate 110 and cannot be taken out.

  Next, a detailed structure of the upper clamp device 300 will be described with reference to FIGS. FIG. 14A is a perspective view showing a state in which the upper clamp device is viewed from the upper left side, and FIG. 14B is a perspective view showing a state in which the upper clamp device is viewed from the lower left side. FIG. 15 is an exploded perspective view showing the upper clamp device. FIG. 16A is a longitudinal sectional view showing a state where the slide member is located at the clamping position, and FIG. 16B is a longitudinal sectional view showing a state where the slide member is located at the retracted position. FIG. 17 is a longitudinal sectional view showing a state in which the slide member is held at the retracted position. FIG. 18A is a longitudinal sectional view showing a state in which the cleaning cloth is pulled out, and FIG. 18B is a longitudinal sectional view showing a state in which the cleaning cloth is sandwiched. FIG. 19 is an enlarged schematic view of a main part for explaining a situation where the cleaning cloth is sandwiched. In the following description, the left side of FIGS. 16 to 19 is the upper side of the upper clamp device 300, the right side of the paper is the lower side of the upper clamp device 300, the upper side of the paper is the front side of the upper clamp device 300, and the lower side of the paper is the upper clamp. The rear side of the apparatus 300 will be described.

  As shown in FIGS. 14 and 15, the upper clamp device 300 includes a metal base member 301 that is fixed to the upper portion of the outer surface of the linear passage cover 104, and a metal that is slidably supported with respect to the base member 301. The sliding member 302 is mainly composed of a pair of left and right tension springs 303 and 303 as urging means for urging the sliding member 302 toward the nipping position where the cleaning cloth 116 is nipped.

  The base member 301 includes a base plate 301a having a substantially rectangular shape in plan view disposed on the outer surface of the linear passage cover 104, and side plates 301b and 301b formed by bending from the left and right sides of the base plate 301a toward the front side. It is configured in a U-shape when viewed from above, and a cleaning cloth 116 can be provided between the both side plates 301b and 301b so as to be drawn out from the upper side toward the lower side. The width dimension between the both side plates 301b and 301b is slightly larger than the width dimension of the cleaning cloth 116, and has a function of guiding the left and right sides of the cleaning cloth 116. In addition, fixing holes 304 are formed at the four corners of the base plate 301a. By attaching fixing screws 305 to the respective fixing holes 304 from the front surface side and fixing them to the outer surface of the linear passage cover 104, linear passage covers are formed. 104 is fixed to the outer surface.

  Between the upper portions of the side plates 301b and 301b, a cylindrical guide bar 306 is installed at a position spaced from the base plate 301a so that the cleaning cloth 116 can be inserted between the base plate 301a and the guide bar 306. It has become. At a position slightly below the guide bar 306 in the base plate 301a, an inclined plate 307 is formed by bending a part of the base plate 301a in the width direction and bending it toward the front side. The inclined plate 307 is formed so as to be inclined upward from the upper side toward the lower side, is inclined about 45 degrees with respect to the base plate 301a (see FIG. 16), and has a rubber plate 308 on the lower side surface thereof. Is provided in the width direction.

  On both sides of the side plates 301b and 301b, on the lower side of the inclined plate 307, elongated hole-like guide grooves 309a and 309b for guiding the slide member 302 to be slidable in the vertical direction of the base member 301 are respectively provided in the vertical direction. It is extended toward. The guide groove 309b is formed in a substantially L shape in a side view, and a locking step 309c for locking (holding) the slide member 302 at the retracted position is formed. Further, locking pieces 310, 310 having locking holes 310a for locking the upper ends of the tension springs 303 are bent inwardly at positions near the guide grooves 309a on the front end sides of the side plates 301b, 301b.

  The slide member 302 is formed in a substantially rectangular shape in plan view, side plates 302b and 302b bent from the left and right sides of the slide plate 302a to the near side, and bent from the lower side of the slide plate 302a to the near side. A lower plate 302c, and an inclined plate 302d bent from the upper side of the slide plate 302a to the front side. The front surface of the base plate 301a and the slide plate 302a are formed on the front side of the base plate 301a of the base member 301. It is provided to be slidable in the vertical direction so that a space S (see FIG. 16) into which the cleaning cloth 116 can be inserted is formed between the rear surface and the rear surface.

  In the slide plate 302a, three round holes 311 penetrating in the front-rear direction are arranged in parallel in the left-right direction, and an opening 312 is formed from the bottom of the slide plate 302a to the lower plate 302c. Through the opening 312, the cleaning cloth 116 inserted through the rear surface side of the slide plate 302 a can be viewed and touched from the front surface side of the slide member 302, so that the twist of the cleaning cloth 116 can be confirmed and the upper side of the slide member 302 can be checked. Thus, it is possible to easily perform the insertion operation from the lower side to the lower side, and the weight of the slide member 302 is reduced.

  Locking holes 313 and 313 are formed on the left and right sides of the opening 312 in the lower plate 302c to lock the lower ends of the tension springs 303 and 303 whose upper ends are locked to the base member 301 side, so that the slide member 302 is free. In such a state, the blade portion 314 formed on the front end side of the inclined plate 302d in the longitudinal direction is constantly urged toward the holding surface 308a of the rubber plate 308 of the base member 301.

  A screw hole 316a to which a guide pin 315a to be inserted into the guide groove 309a is attached is formed on the outer surface of the left and right side plates 302b, 302b, and below that, a guide pin to be inserted into the guide groove 309b. A screw hole 316b to which 315b is attached is formed.

  As shown in the enlarged view in FIG. 15, the guide pins 315a and 315b have a screw portion 317a that is screwed into the screw holes 316a and 316b, and a larger diameter than the screw portion 317a, and are inside the guide grooves 309a and 309b. The cylindrical portion 317b is slidably inserted into the cylindrical portion 317b, and the head portion 317c is larger in diameter than the cylindrical portion 317b and disposed on the outer surface of the side plate 301b. Then, the guide pins 315a and 315b are respectively inserted into the guide grooves 309a and 309b from the outside of the side plate 301b and fixed to the screw holes 316a and 316b, so that the slide member 302 is fixed to the base member 301 with respect to the base plate 301a. Is supported so as to be slidable in the vertical direction.

  The inclined plate 302d is formed so as to be inclined upward toward the upper side, and is inclined about 45 degrees with respect to the slide plate 302a (see FIG. 16). A blade portion 314 made of a triangular concavo-convex portion is formed at the front end edge of the inclined plate 302d in the width direction so that it can easily bite into the cleaning cloth 116.

  Next, the operation state of the upper clamp device 300 configured as described above will be described with reference to FIGS.

  FIG. 16A shows a state in which the slide member 302 is free. In this state, the slide member 302 is biased toward the upper side by the tension spring 303, thereby being positioned at a clamping position where the blade portion 314 of the inclined plate 302 d is pressed against the rubber plate 308.

  FIG. 16B shows a state in which the slide member 302 is pulled downward against the urging force of the tension spring 303. In this state, the slide member 302 is located at a retracted position where the blade portion 314 of the inclined plate 302d is retracted from the rubber plate 308 toward the lower side. Further, when the slide member 302 is released in this retracted position, it is urged upward by the tension spring 303 and moved to the clamping position.

  FIG. 17 shows a state in which the slide member 302 is pulled to the lower side against the urging force of the tension spring 303 and moved to the retracted position, and the guide pin 315b is locked to the locking step 309c. . In this state, since the guide pin 315b is locked to the locking step portion 309c, the slide member 302 is not moved upward by the tension spring 303 even if the slide member 302 is released. Maintained in position. By locking the guide pin 315b to the locking step portion 309c in this manner, the space between the blade portion 314 and the rubber plate 308 can be maintained wide by the tension spring 303, which will be described later. Since the cleaning cloth 116 can be easily inserted and removed between the blade portion 314 and the rubber plate 308, the cleaning cloth 116 can be easily pulled out and replaced.

  Further, the locking hole 310a for locking the upper end of the coil spring 303 is disposed on the front side of the locking hole 313 for locking the lower end, so that the lower portion of the slide member 302 is not only on the upper side but also on the front side. The state in which the guide pin 315b is locked to the locking step portion 309c is maintained by the action of biasing toward the side.

  Next, the lower clamp device 400 will be briefly described with reference to FIG. 20A is a perspective view showing a situation where the lower clamp device is in an open state, and FIG. 20B is a perspective view showing a situation where the lower clamp device is in a clamping state.

  The lower clamp device 400 includes a rubber plate 401 that is fixed to the lower front portion of the linear passage cover 104 and extends in the width direction, and a part of the rubber plate 410 on the left and right sides of the linear passage cover 104 protrudes from the front side. Mounting pieces 403 and 404 attached in this manner, and a clamping member 402 supported on the front portion of the attachment piece 404 so as to be openable and closable.

  The holding member 402 is formed in a substantially U-shaped longitudinal section from a front plate 402a having a horizontally long belt shape, and holding pieces 402b and 402b bent from the upper and lower sides of the front plate 402a toward the front surface of the linear passage cover 104. The right side is attached to the front part of the attachment piece 404 via a hinge 405. A round hole 406 is formed in the front plate 402a, and the cleaning cloth 116 inserted between the front plate 402a and the rubber plate 401 can be seen and touched from the front side of the front plate 402a. It is possible to easily check the twist of the cleaning cloth 116 and insert the cleaning cloth 116.

  On the left side of the rear surface of the front plate 402a, a lock piece 408 that can be engaged and disengaged with a locking hole 407 formed in the attachment piece 403 is supported so as to be slidable in the left-right direction. The left end portion of the lock piece 408 is provided so as to be able to go out and with respect to the insertion port 409 formed in the left piece 402c bent from the left side of the front plate 402a toward the rear surface, and one end is attached to the front plate 402a. The coil spring 411 is constantly biased in a direction in which the left end portion of the lock piece 408 protrudes from the insertion port 409.

  Further, an operation piece 408a is provided on the front surface of the lock piece 408 so as to protrude forward from a guide groove 410 formed in the front plate 402a. The operation piece 408a is picked up to the right side against the urging force of the coil spring 411. And the base of the operation piece 408a is locked to a locking step (not shown) formed in the guide groove 410 so that the left end of the lock piece 408 is inserted into the insertion opening. It can be held at the retracted position retracted inside 409. Further, blade portions 412 and 412 made of triangular concave and convex portions are formed in the width direction in front end edge portions of the sandwiching pieces 402b and 402b, so that the cleaning cloth 116 is easily bited.

  Next, a procedure for stretching the cleaning cloth 116 on the inner surface side of the linear passage cover 104 will be described.

  In order to stretch the cleaning cloth 116 on the inner surface side of the linear passage cover 104, first, the conveyance belt 103 is rotated in a state where the inflow of pachinko balls from the ball inflow port 122 is restricted, and the cleaning cloth 116 remains in the linear passage 115. With all the pachinko balls being lifted and discharged, the linear passage cover 104 is opened as shown in FIG. Then, one end of the long cleaning cloth 116 is hooked from the inner surface side of the linear passage cover 104 to the upper end portion, is drawn outward from the upper end portion, and one end of the drawn cleaning cloth 116 is folded downward. The upper clamp device 300 is inserted from the upper side toward the lower side.

  Specifically, as shown in FIG. 16A, the slide member 302 positioned at the holding position is positioned at the pulling holding position toward the lower side retracted position (see FIG. 17). Then, one end of the cleaning cloth 116 facing the upper side of the base member 301 is inserted from the upper side between the guide bar 306, the base plate 301a and the inclined plate 307 and pulled out to the front side, and further the blade portion 314 and the rubber Inserted in the direction of the white arrow in FIG. 17 between the plate 308 and inserted into the space S formed between the front surface of the base plate 301a and the rear surface of the slide plate 302a, and then pulled out from the lower side (FIG. 18 ( a)).

  When laying the cleaning cloth 116 for the first time, the cleaning cloth 116 must be pulled from the lower side of the upper clamping device 300 in order to apply tension to the cleaning cloth 116 as described later. It is preferable that the cleaning cloth 116 having a dimension is previously extended downward as the surplus portion Z.

  In this way, the cleaning cloth 116 inserted from the upper side of the base member 301 is inserted between the blade portion 314 and the rubber plate 308 and pulled out from the lower side, and the slide member 302 is used as the urging force of the tension spring 303. In the state where the guide pin 315b is locked to the locking step portion 309c and the slide member 302 is held at the retracted position and the space between the blade portion 314 and the rubber plate 308 is widened without being pulled against the lower side. Since it can be performed, workability is improved.

  Next, in a state where one end of the cleaning cloth 116 is drawn downward from the lower side of the clamping device 300, the lower part of the slide member 302 is pushed toward the rear surface side, and the locking step 309c and the guide pin 315b are locked. Release it. As a result, the sliding member 302 slides from the holding position to the clamping position by the urging force of the tension spring 303, and the blade portion 314 is pressed toward the rubber plate 308. It is pinched between the part 314. Further, since the blade portion 314 is always urged by the urging force of the tension spring 303 even when the cleaning cloth 116 is nipped between the rubber plate 308 at the nipping position, the nipping force is not weakened.

  In a state where one end of the cleaning cloth 116 is temporarily clamped by the upper clamp device 300, the lower part of the cleaning cloth 116 laid on the inner surface side of the linear passage cover 104 is folded outward at the lower end portion of the linear passage cover 104. . Here, as shown in FIG. 20A, the clamping member 402 of the lower clamp device 400 is opened, and the lock piece 408 is locked to a locking step (not shown) (held in the retracted position). Then, the cleaning cloth 116 is laid from the lower front side of the rubber plate 401 toward the upper side. Then, the locked state of the locking piece 408 with the locking step (not shown) is released, the clamping member 402 is rotated to the closed position, and the left end portion is pushed toward the mounting piece 403. As a result, when the tip of the lock piece 408 is inserted and locked into the locking hole 407, the cleaning cloth 116 is firmly held between the rubber plate 401 and the blade portion 412 and cannot be pulled out downward. Become.

  In this way, the upper clamp device 300 holds the upper portion of the cleaning cloth 116 folded outward at the upper end of the linear passage cover 104 and drawn downward along the outer surface of the linear passage cover 104. In the state where the lower part of the cleaning cloth 116 folded back outward at the lower end portion of the linear passage cover 104 and pulled upward is clamped by the lower clamp device 400, the inner surface side of the linear passage cover 104, that is, the clean In order to apply tension to the cleaning cloth 116 laid on the part, after the linear passage cover 104 is closed (it may remain open), the surplus part Z extended downward from the lower side of the upper clamping device 300 Pull downward to apply tension.

  In this embodiment, after the upper end of the cleaning cloth 116 is clamped by the upper clamp device 300, the lower portion of the cleaning cloth 116 pulled out from the lower portion of the cleaning section is clamped by the lower clamping device 400. The cleaning cloth 116 is pulled out from the lower side of the cleaning section. After clamping one end of the cleaning cloth 116 by the lower clamping device 400, the upper portion of the cleaning cloth 116 pulled out from the upper section of the cleaning section is connected to the upper clamping apparatus 300. The new cleaning cloth 116 may be pulled out from the upper side of the cleaning section.

  Here, the effect | action of the upper clamp apparatus 300 at the time of providing tension | tensile_strength to the cleaning cloth 116 is demonstrated based on FIG.18 and FIG.19.

  FIG. 18B shows a state where a predetermined portion of the cleaning cloth 116 inserted from the upper side to the lower side of the clamping device 300 is sandwiched between the blade portion 314 and the rubber plate 308. Yes. In this state, as described above, the lower portion of the cleaning cloth 116 is held by the lower clamp device 400. Further, the cleaning surface 116 a that contacts and cleans the pachinko ball on the inner surface of the linear passage cover 104 faces the front surface side. Here, when the surplus portion Z of the cleaning cloth 116 extending downward from the lower side of the base member 301 is pulled downward, the slide member 302 is pushed back downward by the cleaning cloth 116, and the tension spring 303. It moves toward the retracted position against the urging force (see FIG. 18A).

  Specifically, as shown in FIG. 18, the tip 307a of the inclined plate 307 is disposed on the front side (upper side in the drawing) of the rear surface of the guide bar 306 and the rear surface of the slide plate 302a, that is, the base. Since the cleaning cloth 116 inserted from the upper side between the guide bar 306 and the base plate 301a rides on the front end portion 307a of the inclined plate 307 after being arranged at a position away from the plate 301a, the slide Since it is inserted through the rear surface of the plate 302a, the arrangement position of the inclined plate 307 in the cleaning cloth 116 bends in a substantially “h” shape toward the front side in a side view.

  That is, as shown in FIG. 19A in particular, the slide member 302 is stretched diagonally in the front-rear direction between the distal end portion 307a and the bent portion 302e by pulling the excess portion Z of the cleaning cloth 116 downward. The cleaning surface 116a of the provided cleaning cloth 116 is pushed toward the lower side (retracted position) against the urging force of the tension spring 303, and the blade portion 314 is separated from the rubber plate 308 to release the clamping state. Therefore, tension can be applied to the cleaning cloth 116 simply by pulling the excess portion Z of the cleaning cloth 116 downward.

  In addition, since the inclined plate 302d is inclined with respect to the slide plate 302a, the inclined plate 302d, the clean surface 116a, and the like in the state where the slide member 302 is located at the retracted position as shown in FIG. Are separated from each other, and the blade portion 314 is forcibly pulled away from the cleaning cloth 116, so that it is avoided that resistance is applied when the blade portion 314 bites into the cleaning cloth 116 and pulls the cleaning cloth 116 downward. The

  In this manner, the inclined plate 302d slides at least at the retracted position so that the blade 314 is separated from the cleaning surface 116a of the cleaning cloth 116 that is stretched obliquely in the front-rear direction between the distal end portion 307a and the bent portion 302e. What is necessary is just to incline with respect to the board 302a, and the inclination angle with respect to the slide board 302a is arbitrary.

  Next, when the surplus portion Z is released in the state where the surplus portion Z is pulled downward and tension is applied as described above, the slide member 302 that has been pushed toward the retreat position side by the cleaning surface 116a of the cleaning cloth 116. Becomes free, and is urged toward the holding position by the urging force of the tension spring 303 to slide (see FIG. 18B).

  At this time, particularly when the slide member 302 moves instantaneously toward the clamping position, the inclined plate 302d comes into contact with the cleaning surface 116a of the cleaning cloth 116 (see FIG. 19B). Further, the cleaning surface 116a of the cleaning cloth 116 is pushed toward the clamping position side by the inclined plate 302d, and the blade portion 314 moves to the upper side of the tip portion 307a at the rear surface side position of the tip portion 307a. By entering the rear surface side of the plate 307, the cleaning cloth 116 is folded back to the upper side with the tip end portion 307a as a fulcrum, and the frictional resistance is caused by the cleaning surface 116a of the folded cleaning cloth 116 coming into contact with the blade portion 314. The cleaning cloth 116 that is increased (see FIG. 19C) and folded back at the tip portion 307a is drawn toward the upper side of the tip portion 307a. The cleaning cloth 116 is sandwiched between the rubber plate 308 and the blade portion 314 at the clamping position where the blade portion 314 contacts the rubber plate 308 (see FIG. 19D).

  In this way, by releasing the surplus portion Z from the state of FIG. 19A, the cleaning cloth 116 that has been pulled downward is pulled back toward the upper side by the restoring force, and at the same time, the slide member 302 is moved. Since the cleaning cloth 116 is instantly slid to the clamping position and clamped between the rubber plate 308, the cleaning cloth 116 is held at the clamping position before being loosened while the tension of the cleaning cloth 116 is substantially maintained.

  In particular, as shown in FIG. 19, the holding part 308a with which the blade part 314 comes into contact with the rubber plate 308 holding the cleaning cloth 116 is arranged on the upper side with respect to the tip part 307a, thereby returning toward the upper side. The cleaning cloth 116 to be pulled is pulled upward with the tip portion 307a as a fulcrum, and the blade portion 314 enters the upper side of the tip portion 307a so as to be sandwiched. Therefore, the cleaning cloth 116 is cleaned until the blade portion 314 reaches the clamping position. It is prevented that the cloth 116 is loosened and the tension is greatly attenuated.

  Further, since the rubber plate 308 provided with the clamping portion 308a is provided on the inner surface side of the inclined plate 307 inclined toward the rear surface side toward the upper side with respect to the moving direction of the slide member 302, the blade portion 314 is provided. After being brought into contact with the sandwiching portion 308a, it is pushed into the deformable rubber plate 308 so that the cleaning cloth 116 folded back with the tip end portion 307a as a fulcrum acts to the upper side. A tension is applied to 116.

  Further, the blade portion 314 is formed at the tip of the inclined plate 302d that is inclined toward the front side toward the upper side with respect to the moving direction of the slide member 302 so as to be orthogonal to the clamping portion 308a. Since the tops of the convex portions of the blade portion 314 are in line contact with the portion 308a, the frictional resistance against the cleaning cloth 116 is increased.

  In order to further increase the tension, the surplus portion Z may be further grasped and pulled downward from the state of FIG. Then, as described above, the blade portion 314 is pushed out toward the lower side by the cleaning surface 116a of the cleaning cloth 116 folded back to the upper side at the tip portion 307a, and FIGS. 19 (c), 19 (b) and 19 (a). In this order, the slide member 302 is pushed back toward the retracted position against the urging force of the tension spring 303, and the clamping state is released. Therefore, the excess portion Z can be pulled downward to further apply tension. . When the surplus portion Z is released in a state where an appropriate tension is applied, the slide member 302 is urged again toward the clamping position to clamp the cleaning cloth 116.

  Further, as shown in FIG. 19C, immediately after the blade portion 314 is pushed out toward the lower side by the cleaning surface 116a of the cleaning cloth 116 folded back at the top end portion 307a and separated from the holding portion 308a. , The surface of the inclined plate 302d facing the clean surface 116a is in contact with the clean surface 116a, but the tops of the convex portions of the blade portion 314 are immediately separated from the clean cloth 116a. That is, since the clamping surface (tip surface of the inclined plate 302d) of the blade portion 314 is provided in parallel to the clamping portion 308a, the leading edge portion 307a is supported as the cleaning cloth 116 is pulled out to the lower side. The inclination of the clean surface 116a changes in the opposite direction and differs from the inclination of the clamping surface in the blade portion 314. Therefore, before moving to the retracted position, the clamping surface of the blade portion 314 is separated from the clean surface 116a, so that the clean cloth 116 can be easily pulled out.

  In this way, by repeatedly performing the operation of pulling the surplus portion Z downward and then releasing it, the tension of the cleaning cloth 116 can be gradually increased rather than at one time. Since it is not necessary to pull the surplus portion Z while pulling downward against the urging force of the tension spring 303, even if the tension of the cleaning cloth 116 decreases due to use, the tension is frequently increased by simple operation. It becomes possible.

  In particular, in this embodiment, when the cleaning cloth 116 is laid and the lifting device 25 is driven, the cleaning cloth 116 whose lower portion is held by the lower clamp device 400 is moved upward by the pachinko balls P lifted by the conveyor belt 103. It is pulled toward Therefore, since it is considered that the tension gradually weakens due to the use of the cleaning cloth 116 as it is stretched, it is necessary to frequently apply the tension after the amusement store is closed. Since it is only necessary to pull downward, anyone can easily apply tension.

  Further, when the cleaning surface 116a of the cleaning cloth 116 laid on the cleaning portion is contaminated, the used cleaning surface 116a is pulled out from the upper part of the linear passage cover 104, and the new cleaning surface 116a is removed from the cleaning portion 116a. Just pull it out.

  In this case, while the linear passage cover 104 is closed without being opened, the clamping member 402 of the lower clamp device 400 is opened to release the clamping state, and in this state, the lower clamp device 400 extends downward from the lower side. The surplus portion Z that is present is directed downward. Since the cleaning surface 116a is disposed toward the front surface side, the excess portion Z is moved downward while visually recognizing the upper end portion of the linear passage cover 104, and the upper end portion of the linear passage cover 104 is not contaminated. When the new clean surface 116a is pulled out, the surplus portion Z is released. Then, the clamping member 402 of the lower clamping device 400 is closed to be in the clamping state, and then the surplus portion Z extending downward from the lower side of the upper clamping device 400 is pulled downward and tension is applied. If the surplus part Z is released, the upper part of the cleaning cloth 116 is clamped by the upper clamp device 400, and a new cleaning surface 116a is stretched over the cleaning part.

  As described above, the upper clamping device 300 according to the embodiment of the present invention includes the distal end portion 307a of the inclined plate 307 and the distal end portion 307a as fixed portions provided at positions away from the outer surface of the linear passage cover 104. Of the rubber plate 308 fixed to the inclined plate 307 as the first holding portion disposed at a position shifted in the front-rear direction with respect to the tip end portion 307a. It is slidable along the outer surface of the linear passage cover 104 between a clamping position where the cleaning cloth 116 is clamped between the clamping part 308a and the clamping part 308a and a retreat position where the cleaning cloth is retracted downward from the clamping position. A straight passage cover 104, and a blade portion 314 of the inclined plate 302d as a second holding portion disposed on the tension plate 303 and a tension spring 303 as a biasing means for biasing the clamping portion 308a upward. The cleaning cloth 116 that is folded back from the upper end of the knives is looped over at the front end portion 307a so that it can be folded back upward, inserted between the sandwiching portion 308a and the blade portion 314, and drawn out below the blade portion 314. Then, when the blade portion 314 is biased from the retracted position toward the clamping position by the tension spring 303, the cleaning cloth 116 is held between the holding section 308a and tension is applied to the cleaning cloth 116. When the cleaning cloth 116 is pulled out downward, the blade portion 314 is pressed against the cleaning cloth 116 and moved from the clamping position to the retracted position against the urging force of the tension spring 303. It is comprised so that clamping may be cancelled | released.

  Thus, the cleaning cloth 116 drawn out from the upper part of the cleaning part toward the lower part is folded back to the upper part by the tip part 307a and is the holding part 308a and the second holding part as the first holding part. It is inserted between the blade portion 314, meanders in a substantially Z shape, and is drawn out to the lower side. In this state, when the cleaning cloth 116 is pulled out toward the lower side, the cleaning cloth 116 folded back to the upper side at the front end portion 307a is drawn out to the lower side with the front end portion 307a as a fulcrum, and the blade portion 314 is cleaned by the cleaning surface 116a. Is returned to the lower side against the urging force of the tension spring 303, so that the clamping state can be easily released simply by pulling out the cleaning cloth 116. Further, when the surplus portion Z is released, the blade portion 314 urged toward the holding position by the tension spring 303 is pressed and held by the holding portion 308a while pushing the cleaning cloth 116 upward, so that the cleaning cloth The tension can be gradually increased by simply repeating a simple operation of pulling out 116.

  Further, in the upper clamp device 300, the sliding surface of the guide rod 306, the inclined plate 307 and the tip 307a, the inclined plate 302d, and the sliding plate 302a with the cleaning cloth 116 is constituted by the surface of a metal plate, at least Since the blade portion 314 and the rubber plate 308 are made of a sliding portion having a smaller frictional resistance than the anti-slip portion of the rubber plate 308, the excess portion Z can be easily pulled downward to apply tension to the cleaning cloth 116, and clean. The cleaning cloth 116 is not damaged by contact with the cloth 116.

  Further, since the base member 301 and the slide member 302 are formed into a flat plate shape with a thin front and rear width by bending a metal plate, the base member 301 and the slide member 302 may protrude greatly from the outer surface of the linear passage cover 104 to the near side. Therefore, there is no hindrance when the lifting device 25 is installed in a narrow space in the gaming machine installation island 1.

  FIG. 21 is a schematic diagram showing a configuration of an upper clamp device 300 ′ as a modification of the present invention.

  In the present embodiment, the cleaning cloth 116 is folded back to the upper side at the front end portion 307a of the inclined plate 307 provided with the rubber plate 308. However, the upper clamping device 300 ′ as a modification of FIG.

The portion 307a is arranged closer to the base plate 301a than the rubber plate 308 and the blade portion 314. That is, as shown in FIG. 21, even if the arrangement positions of the rubber plate 308 and the blade portion 314 in the front-rear direction with respect to the tip portion 307a are reversed. Good.

  Further, the rubber plate 308 having the sandwiching portion 308a is provided so as to be inclined with respect to the moving direction of the slide member 302, but may be arranged in a direction orthogonal to the slide moving direction.

  Moreover, although the blade part 314 was formed at the front-end | tip of the inclination board 302d inclined with respect to the slide board 302a, you may form in the upper end edge part of the slide board 302a.

  Even in the upper clamp device 300 ′ as a modified example configured as described above, the same operations and effects as the upper clamp device 300 are obtained.

  Further, in the upper clamping devices 300 and 300 ′, the first clamping part is constituted by the rubber plate 308, and the second clamping part is constituted by the blade part 314. If it can increase, it will not be limited to these rubber | gum and a blade part.

  In the present embodiment and the modification, the upper clamp device 300 is provided only to hold the upper part of the cleaning cloth 116 folded back at the upper end of the linear passage cover 104, and the lower part is a separate lower clamp. Although held by the apparatus 400, the upper part of the cleaning cloth 116 folded at the lower end of the linear passage cover 104 may also be held by the upper clamp apparatus 300. In this case, the upper clamp device 300 is used in an upside down orientation.

  That is, the lower clamp device is provided between the front end portion 307 a of the inclined plate 307 as a fixing portion provided at a position away from the outer surface of the linear passage cover 104, and between the front end portion 307 a and the lower end portion of the linear passage cover 104. Between the clamping part 308a and the clamping part 308a of the rubber plate 308 fixed to the inclined plate 307 as the first clamping part arranged at a position displaced in the front-rear direction with respect to the tip part 307a An inclined plate as a second holding portion that is slidably disposed along the outer surface of the linear passage cover 104 between a holding position for holding the cleaning cloth 116 and a retracted position retracted upward from the holding position. 302 d of blade part 314 and tension spring 303 as an urging means for urging the clamping part 308a downward, and the cleaning cloth 116 folded back from the lower end part of the linear passage cover 104 is attached to the tip part It is constructed so that it can be folded back downward at 307a, inserted between the holding part 308a and the blade part 314 and pulled out above the blade part 314, and the blade part 314 is clamped from the retracted position by the tension spring 303. By being biased toward the position, the cleaning cloth 116 is held between the holding portions 308a and tension is applied to the cleaning cloth 116, and the cleaning cloth 116 is pulled upward, The blade 314 is pressed by the cleaning cloth 116 and moved from the holding position to the retracted position against the urging force of the tension spring 303, and the holding of the cleaning cloth 116 is released.

  Further, in this embodiment and the modification, the cleaning cloth 116 stretched in the transfer direction of the pachinko sphere so as to contact the pachinko sphere that transfers the linear passage 115 is a linear passage cover that covers the linear passage 115. 104 is drawn outward from the upper end and lower end of 104, and is folded along the outer surface of the linear passage cover 104, but is not necessarily drawn outward from the upper end and lower end of the linear passage cover 104. For example, the linear passage cover 104 may be provided so as to be able to be drawn outward from a pair of upper and lower slits formed between the upper end portion and the lower end portion.

  Further, in the present embodiment and the modification, the upper clamp device 300 and the lower clamp device 400 are disposed at the upper and lower positions of the outer surface of the linear passage cover 104, but above and below the linear passage cover 104 in the main body 100. It may be disposed at a position, and is not limited to the one disposed on the linear passage cover 104.

  In the present embodiment and the modification, the inclined plate 307 having the rubber plate 308 and the tip portion 307a are provided on the base member 301, and the blade portion 314 is provided on the slide member 302. It may be arranged.

  In this embodiment and the modification, the inclined plate 307 having the rubber plate 308 is fixed to the base member 301. However, at least only the tip 307a is fixed to the base member 301, and the inclined plate 307 and If the rubber plate 308 is disposed on the upper side of the tip portion 307a, for example, the inclined plate 307 and the rubber plate 308 may move toward the upper side and the lower side when pressed by the blade portion 314. Good.

  In this embodiment, as an example of the transfer device of the present invention, the lifting device 25 that lifts the game ball from the lower portion of the main body 100 extending in the vertical (vertical) direction toward the upper portion is applied. The invention is not limited to this, and the upper portion of the main body that extends in the vertical (vertical) direction is not necessarily limited as long as it is a transfer device that transfers the game ball flowing into the transfer surface of the main body 100 by the transfer means and discharges it from the main body 100. The game ball is not lifted from the bottom to the bottom. For example, the game ball flowing from one end side of the main body 100 extending in the diagonally up and down direction or the horizontal (lateral) direction is horizontally (horizontal) by the transfer means. The present invention is also applicable to a transfer device that transfers in the direction and discharges from the other end side of the main body 100.

  Further, in the present embodiment and the modified example, a conveying belt 103 that is stretched around the upper roller 101 and the lower roller 102 provided above and below the main body 100 and circulates by the rotation of the upper roller 101 and the lower roller 102, and the lower roller , And a pachinko ball pressed against a conveyor belt 103 as an example of a transfer means that is driven to rotate by driving the lift motor 80 and rotating the lower roller 102. Although the (transfer) lifting device 25 is applied, for example, it may be a lifting device that lifts pachinko balls by rotationally driving a drive sprocket (not shown) provided below the linear passage 115. In this case, for example, an opening is formed on the side surface of the linear passage 115 formed by a pipe pipe or the like, and along the linear passage 115 through the opening. It is sufficient to clean by contacting the pachinko ball clean cloth 116 stretched.

  Next, bearing structures of the upper roller 101, the lower roller 102, the driven rollers 107 and 109, and the tension roller 108 on which the conveying belt 103 is stretched will be described with reference to FIGS. FIG. 22 is a perspective view showing a state in which the upper inside of the lifting device is viewed from the rear lower side. FIG. 23 is a left side view showing the upper inside of the lifting device. 24A is a rear view showing a state in which the upper roller is disposed at the uppermost position, FIG. 24B is a rear view showing a state in which the upper roller is disposed at the intermediate position, and FIG. 24C is a lowermost position. It is a rear view which shows the state arrange | positioned in. FIG. 25 is a perspective view showing a state where the lower part of the lifting device is viewed from the rear left side. FIG. 26 is a left side view showing the lower part of the lifting device. 27A is a cross-sectional view taken along the line H-H in FIG. 26, and FIG. 27B is a cross-sectional view taken along the line JJ in FIG. 26. FIG. 28 is a rear view showing a lower portion of the lifting device.

  Since the conveyance belt 103 may be replaced due to deterioration or damage due to foreign matter, for example, the conveyance belt 103 can be removed from the main body 100, and the contact position and tension with respect to the roller can be adjusted. Hereinafter, the detailed structure of each roller will be described.

  As shown in FIGS. 22 and 23, the upper roller 101 is disposed at the upper end of the main body 100 so as to be rotatable around a rotation shaft 101a facing in the left-right direction (see FIG. 5). Specifically, the left and right ends of the rotating shaft 101a projecting to the left and right sides of the upper roller 101 are movable shaft support members 500 supported in a vertically movable manner within a cylinder 100a disposed in the main body 100. Is pivotally supported. A guide roller 502 that comes into contact with a cam 503 (described later) is provided below the movable shaft support member 500 so as to be rotatable around a rotation shaft 501 that faces in the front-rear direction. In addition, a fixing bolt 507 is attached to the rear surface of the movable shaft support member 500 and is inserted into a U-shaped groove that is formed on the front plate of the cylindrical body 100a and faces the vertical direction.

  A fixed plate 504 is fixed to a position below the movable shaft support member 500 in the cylindrical body 100a, and a cam 503 for raising and lowering the movable support member 500 is provided on the rear surface side of the fixed plate 504 in the front-rear direction. It is attached to the periphery of the eccentric shaft 505 facing the direction of eccentric rotation.

  The upper part of the peripheral surface of the cam 503 is disposed so that the lower part of the peripheral surface of the guide roller 502 disposed above can be brought into contact therewith, and the upper roller 101 and the movable support member 500 are fixed by the fixed plate 504 via the cam 503. It is received from below. The cam 503 is made of a disk-like metal material that is thinner than the thickness of the guide roller 502, and has different lengths (radius) from the eccentric shaft 505 to the peripheral surface as shown in the enlarged view of FIG. Further, on the peripheral surface of the cam 503, arc-shaped concave portions 503a to 503d into which a part of the peripheral surface of the guide roller 502 is fitted are formed at a plurality of locations.

  Among the recesses 503a to 503d, the recess 503a has the shortest distance from the eccentric shaft 505, and then the distance from the eccentric shaft 505 decreases in the order of the recesses 503b, 503c, and 503d. In other words, the recesses 503a and 503d, the recesses 503b and 503b, and the recesses 503c and 503c are formed at symmetrical positions on the left and right lines across a virtual line that connects the center position of the recess 503a and the recess 503d and the eccentric shaft 505. Yes. The recess 503a has the largest depth, and the other recesses 503b, 503c, and 503d are formed to have substantially the same depth.

  A long hexagon nut 506 is fixed to the rear surface of the cam 503 so as not to rotate relative to the eccentric shaft 505 protruding to the rear surface side of the cam 503. The rear end portion of the hexagon nut 506 is disposed so as to face an insertion port formed in the rear plate of the cylindrical body 100a, and the hexagon nut 506 is rotated rightward or leftward with a tool such as a spanner. At the same time, the cam 503 can be rotated. A hexagonal groove or the like may be formed on the rear end surface of the hexagon nut 506 so that it can be rotated by a hexagon wrench or the like.

  In the use state in which the conveyor belt 103 is stretched, the concave portion 503d is positioned at the upper portion and the lower peripheral surface of the guide roller 502 is fitted into the concave portion 503d. It is fixed to the body 100a so as not to move up and down. In addition, you may make it regulate raising / lowering by restricting rotation of the cam 503. FIG. In this state, since the upper roller 101 is disposed at the uppermost position, a predetermined tension is applied to the transport belt 103 (see FIG. 24A).

  In order to remove the conveyor belt 103 from the upper roller 101, the fixing state by the fixing bolt 507 is released, and the hexagon nut 506 is rotated right or left with a tool in the use state of FIG. As a result, the recess 503d of the cam 503 is retracted from the upper position, and the recesses 503c, 503b, and 503a are arranged in the order of the recesses 503c, 503b, and 503a (see FIG. 24B). Is placed at the lowest position. In this state, no tension is applied to the conveyor belt 103, so that the conveyor belt 103 can be easily detached from the upper roller 101. Further, in order to stretch the conveying belt 103, an operation reverse to the above operation is performed to rotate the cam 503 and raise the upper roller 101.

  As described above, a plurality of concave portions 503a to 503d having different distances from the eccentric shaft 505 are formed on the peripheral surface of the cam 503, and the distance from the eccentric shaft 505 to the peripheral edge is gradually displaced from the concave portion 503a toward the concave portion 503d. Therefore, the tension applied to the conveyor belt 103 can be increased or decreased in stages. Therefore, for example, when the fixing state by the fixing bolt 507 is released in order to lower the upper roller 101 from the uppermost position to the lowermost position, the upper roller 101 does not drop suddenly due to the tension. Can be secured. Further, since it is not necessary to raise the upper roller 101 from the lowermost position to the uppermost position at the same time, not only a strong force is required, but also the reverse rotation due to the reaction during the rotation operation is prevented. The roller 101 can be raised stepwise and safely.

  In this embodiment, six recesses 503a to 503d are formed on the peripheral surface, but the quantity can be arbitrarily changed. The recesses 503b and 503c are arranged symmetrically on the left and right, and can be moved up and down in three stages even when rotating clockwise or counterclockwise. That is, three recesses are formed on the half circumferential surface, but the recesses 503a and 503d are adjacent to each other. The plurality of recesses may be formed from the recesses 503a to the recesses 503d so that they can be moved up and down stepwise by one rotation.

  Next, the structure of the driven rollers 107 and 109 and the tension roller 108 will be described with reference to FIGS.

  As shown in FIG. 25, driven rollers 107 and 109 and a tension roller 108 are provided on the lower rear side of the main body 100 so as to span the lower part of the lowering path of the conveyor belt 103. The rotation shaft 108 a of the tension roller 108 is pivotally supported by a pair of left and right tension adjustment pivot support members 551 (see FIG. 27) provided on the left and right sides of the support plate 550 provided at the lower portion of the main body 100. The left and right ends of the rotation shaft 107a of the driven roller 107 arranged above the tension roller 108 and the rotation shaft 109a of the driven roller 109 arranged below the tension roller 108 are U-shaped open / close plates 552 that open toward the front side. The left and right plates 553a and 553b are rotatably supported.

  Flange pieces 554a and 554b are bent outward from the front ends of the left and right plates 553a and 553b, and the right flange piece 554b is hinged to the inner surface of the side plate 550b bent backward from the support plate 550 ( 27) and can be opened and closed between the arrangement position shown in FIGS. 26 and 27 and the open position shown in FIG.
