After being guided, it falls into the downflow groove 9L. That is, the counted balls counted by the counting device 15 are returned to the flow-down groove 9L disposed on the left side inside the game island 1.

  As shown in FIGS. 1 and 3, the guide rod 19 has a horizontal plane part 19a having a predetermined front-rear width dimension and substantially horizontal in the front-rear width direction, and both end sides in the front-rear width direction of the horizontal plane part 19a. It is made of a single metal plate formed by bending inclined surface portions 19b, 19b that are continuously provided so as to incline upward from the outside, and has a predetermined height in the center in the front-rear width direction inside the downflow groove 9L. In the position, it is extended so that it may incline below toward the lift cleaning apparatus 25 side from the return path 16. Note that a rubber protective sheet (not shown) is laid on the top surface of the guide rod 19 so that the pachinko ball comes into contact with the flowing down pachinko ball or falls from above the game island 1 ( For example, damage to the guide cage 19 caused by the ball tank 6 of the pachinko gaming machine 2, the supply cage 4, the overflow cage 12, etc.) is prevented.

  Further, as shown in FIG. 1, the downstream end of the guide rod 19 extends to a partition plate 21 erected on the lifting and cleaning device 25 side inside the flow-down groove 9 </ b> L. The counting ball that flows down is dropped to the upstream side of the partition plate 21 in the flow-down groove 9L. The counting sphere flowing down on the guide rod 19 is inclined from the horizontal surface portion 19a by colliding with a ball receiving plate (not shown) facing in the width direction provided at the downstream end or on the downstream end. It rides on the surface portion 19b and falls from the outer edge of the inclined surface portion 19b (see FIG. 4).

  The ball that has dropped to the upstream side of the partition plate 21 in the flow-down groove 9L passes through a communication port 21a (see FIG. 1) formed in the lower part of the partition plate 21 and is formed downstream of the partition plate 21. After flowing into the merging portion 22, it is supplied to the lifting and purifying device 25 via the connecting rod 10 </ b> L and the merging passage 11 described later.

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.

  On the inner surface of the linear passage cover 104, as shown in FIG. 7 in particular, a plurality of rows of substantially hemispherical grooves 113 for forming the 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 game balls P in the linear passages 115 guided by the concave grooves 113 are pressed against the conveyor belt 103 by the passage plates 114, so that the inside of the passage is directed upward by the movement of the conveyor belt 103. It is moved and lifted. That is, the surface (inner surface) facing the game ball in the passage plate 114 constitutes a transfer surface for the game ball.

  In addition, a cleaning cloth 116 as a cleaning member for cleaning the game ball transported in each passage is laid on the inner surface side of the passage plate 114, so that the game is played by the passage plate 114 via the cleaning cloth 116. When the ball P is pressed toward the transport belt 103, the game ball P is transferred while being in sliding contact (contact) with the cleaning cloth 116 due to the movement of the transport belt 103. (Polished). That is, the lifting and cleaning device 25 in the present embodiment lifts the game 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 game 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. 6) and 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. 6) and is 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 is necessary to hold it 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 contact the game ball. When the sliding contact surface with the game ball becomes dirty, 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 arranged on the upper side or the lower part is pulled out from the upper part or the lower part, and the unused part is arranged in the cleaning part of the linear passage 115 so that it can be replaced. To have.

  As shown in FIG. 6, the linear passage 115 formed by the linear passage cover 104 is formed on the front side of the main body 100 from the rotation shaft 101 a to the rotation shaft 102 a, that is, on the ascending side of the conveyance belt 103. ing. Then, the game ball P transferred upward through 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 rounded passage 121 formed by the rounded passage cover 105 described above is formed, and flows in from an inlet 37 provided at the lower front side of the main body 100. The game ball is guided toward the upper straight passage 115.

  A game ball P flowing down the ball introduction passage 123 formed by the ball introduction passage cover 106 provided at the inlet 37 on the upstream side of the round passage cover 105 is introduced into the round passage 121. ing. In addition, the inflow port 37 is provided on the lower back side of the main body 100 and connected to the merging passage 11 constituting a part of a collection passage for collecting game balls discharged from the plurality of pachinko gaming machines 2.

  As shown in FIG. 8, the shutter devices 200L and 200R provided on the connecting rods 10L and 10R are movable plates 201L and 201R provided so as to be able to be moved in and out of the connecting rods 10L and 10R, and the movable plates 201L and 201R. The shutter motors 202L and 202R are configured to move between an open position for retracting the connection rods 10L and 10R upward and a closed position protruding toward the connection rods 10L and 10R. That is, in the shutter devices 200L and 200R, the movable plates 201L and 201R are moved to the open position to allow the game ball to flow down to the inlet 37, and the movable plates 201L and 201R are moved to the closed position to play the game. It is possible to change to a non-permitted state where the flow of the sphere to the inlet 37 is not permitted (a restricted state where flow is restricted). In addition, the shutter devices 200L and 200R are disposed at locations where the left and right movable plates 201L and 201R are spaced apart from each other by the same predetermined distance L1 from the substantially central position in the left and right direction of the inlet 37 of the lift cleaning device 25.

  Further, proximity sensors 210L and 210R that detect game balls that flow down in the flow-down grooves 9L and 9R and are supplied to the flow-in port 37 through the communication port 10a are provided in the flow-down grooves 9L and 9R. Proximity sensors 210L and 210R are disposed at the same predetermined distance L2 from movable plates 201L and 201R, respectively. In this embodiment, the distance L2 is longer than the distance L1, but the distance L2 may be the same as or shorter than the distance L1.

  In the present embodiment, when the shutter devices 200L and 200R are in the non-permitted state, the flow of the game ball is restricted by the movable plates 201L and 201R at the connection rods 10L and 10R, and the upstream side of the connection rods 10L and 10R. The game balls that are pumped and cleaned by the pumping and cleaning device 25 toward the flow-down grooves 9L and 9R are retained (standby). Further, when the game balls are detected continuously for a predetermined time (for example, 10 seconds) by the proximity sensors 210L and 210R, the game balls to be lifted and cleaned by the lift cleaning device 25 are dropped from the connection rods 10L and 10R. Assuming that a predetermined amount (for example, the number of game balls retained from the movable plates 201L and 201R to the position where the proximity sensors 210L and 210R are present) stays over 9L and 9R, a condition for starting the lifting and cleaning operation described later is established. To do.

  On the other hand, when the shutter devices 200L and 200R are in the permitted state, the proximity sensors 210L and 210R play the game ball in a state where the flow restriction of the game ball by the movable plates 201L and 201R is released by the connecting rods 10L and 10R and can flow down. Is not detected for a predetermined time (for example, 10 seconds), a predetermined amount (for example, movable plate 201L) of game balls to be lifted and cleaned by the lifting and cleaning device 25 from the connecting rods 10L and 10R to the flow-down grooves 9L and 9R. , 201R to the proximity sensors 210L, 210R, the number of game balls staying until a certain position) is not staying more than, the stop condition of the lifting cleaning operation described later is established.

  In the following description, the proximity sensors 210L and 210R are determined to be on when the proximity sensors 210L and 210R detect the game balls continuously for a predetermined time (for example, 10 seconds), and the proximity sensors 210L and 210R determine the game balls. Is not detected for a predetermined time (for example, 10 seconds) or longer, the proximity sensors 210L and 210R are determined to be off. If the proximity sensors 210L and 210R are determined to be on, the proximity sensors 210L and 210R are determined to be on until the proximity sensors 210L and 210R are determined to be off, and the proximity sensors 210L and 210R are determined to be on. If it is determined to be off, the proximity sensors 210L and 210R; the proximity sensors 210L and 210R are determined to be off until determined to be on.

In the present embodiment, the detecting means for determining whether or not the game balls to be lifted and cleaned by the lifting and purifying device 25 are staying over a predetermined amount from the connecting rods 10L and 10R to the flow-down grooves 9L and 9R. As the proximity sensors 2 1 0L and 2 1 0R are applied, detection switches other than the proximity sensors may be applied. In the present embodiment, the number of game balls that can stay from the movable plates 201L and 201R to the positions of the proximity sensors 2 1 0L and 2 1 0R is set in advance, and the proximity sensors disposed at predetermined locations of the flow-down grooves 9L and 9R. 2 1 0L, 2 1 0R detects the game ball, so that the game ball to be lifted and cleaned by the lifting and cleaning device 25 stays more than a predetermined amount from the connecting rods 10L and 10R to the flow-down grooves 9L and 9R However, the present invention is not limited to this. For example, the game balls discharged from each pachinko gaming machine 2 or the out ball tank are counted, and the counted game balls are counted. Based on the number, it may be determined whether or not the game balls to be lifted and cleaned by the lift and cleaning device 25 are staying more than a predetermined amount from the connecting rods 10L and 10R to the flow-down grooves 9L and 9R. , Take the recovery passage It may be determined based on the weight of skill sphere.

  FIG. 9A shows an example of the circuit configuration of the lift cleaning device 25. The lift cleaning device 25 is equipped with various circuits for controlling the drive of the lift cleaning device 25. For example, the lift cleaning substrate 221 takes in detection signals from the lift cleaning control controller 220 for controlling the driving of the lift cleaning device 25 and the proximity sensors 210L and 210R for detecting the game balls, for example. A switch circuit 223 that transmits to the controller 220 for control, an output circuit 224 that transmits a motor drive signal from the controller 220 for lifting and cleaning control to the shutter motors 202L and 202R, and the lifting and cleaning motor 80 are mounted.

  The controller 220 for lifting and cleaning control includes a ROM (ReadOnlyMemory) 230 that stores a program for lifting and cleaning control, a RAM (RandomAccessMemory) 231 that provides a work area for lifting and cleaning control, and a controller for lifting and cleaning control. And a CPU (Central Processing Unit) 232 that executes a control operation and an I / O (Input / Output port) 233.

  Power is supplied to the lifting and cleaning control controller 220 via an inverter 240 for converting power to be supplied to the lifting and cleaning device 25 from DC power to AC power. In addition, as shown in FIG. 8, the inverter 240 is housed in a state covered with a metal box 241, so that it is possible to avoid affecting peripheral devices due to noise generated from the inverter 240. In addition, the lifting and cleaning control controller 220 is connected to an island controller 250 that is installed on the game island 1 and connected to various devices (for example, the counting device 15 and the like) in the game island 1.

  As shown in the explanatory diagram of FIG. 9B, the lifting and cleaning control controller 220, based on the detection result of the game ball by the proximity sensors 210L and 210R, the lifting and cleaning motor 80 and the shutter of the lifting and cleaning device 25. Drive control of the motors 202L and 202R is performed. Specifically, the lifting and cleaning control controller 220 puts the shutter devices 200L and 200R into the non-permitted state in the initial driving state of the lifting and cleaning device 25. Then, when it is determined that the game balls to be lifted and cleaned by the lifting and purifying device 25 from the connecting rods 10L and 10R toward the flow-down grooves 9L and 9R stay, and are any of the proximity sensors 210L and 210R; (Proximity sensors 210L, 210R; on), the game balls to be lifted and cleaned by the lifting and cleaning device 25 are staying more than a predetermined amount from the connecting rods 10L and 10R to the flow-down grooves 9L and 9R. Assuming that the operation start condition is satisfied, the movable plates 201L and 201R are closed by the shutter motors 202L and 202R on the side corresponding to the proximity sensor determined to be on when the set cleaning start waiting time (ta) has elapsed. To the open position, the shutter devices 200L and 200R are allowed, and the lifting and cleaning motor 80 is driven to start the lifting and cleaning operation.

  In addition, after starting the lift cleaning operation, when it is determined that any of the proximity sensors 210L, 210R; off (proximity sensors 210L, 210R; off), the game to be cleaned by the lift cleaning device 25 The shutter motor 202L on the side corresponding to the proximity sensor determined to be off is determined that the ball has not accumulated more than a predetermined amount from the connecting rods 10L, 10R to the flow-down grooves 9L, 9R. , 202R to move the movable plates 201L, 201R from the open position to the closed position and put the shutter devices 200L, 200R into the non-permitted state, and then when the predetermined cleaning stop waiting time (tb) has passed, the pump is cleaned. The driving of the motor 80 is stopped, and the lifting and cleaning operation is stopped.

  This cleaning stop waiting time (tb) is set to the time required for all the game balls that have already passed through the movable plates 201L and 201R to be lifted when the inflow of the game balls to the lift cleaning device 25 is restricted. It is preferable to do. Specifically, in addition to the game balls remaining in the lifting and cleaning device 25 when the movable plates 201L and 201R move to the closed position, the game balls on the downstream side of the movable plates 201L and 201R, that is, FIG. As shown in FIG. 8, the time required for all the game balls staying in the distance L1 from the movable plates 201L, 201R to the inflow port 37 to be supplied into the lift cleaning device 25 and discharged from the discharge port 38, Is done. Therefore, when it is determined that the proximity sensors 210L and 210R are off (proximity sensors 210L and 210R; off), when the cleaning stop waiting time (tb) has elapsed, the pump cleaning drive of the pump cleaning device 25 is stopped. Thus, after all the game balls remaining in the lifting and cleaning device 25 and the game balls in the junction passage 11 and the connecting rods 10L and 10R are lifted, at least the gaming balls remain in the lifting and cleaning device 25. Lifting and cleaning drive can be stopped.

  In this way, when the lift cleaning drive is intermittently performed, when the lift drive is stopped, the game ball does not remain in the lift path, so that the load caused by the game ball when restarting the lift cleaning drive is resumed. It is possible to start the driving of the lifting and cleaning motor 80 in a state where it is not applied (the load applied at the initial stage of driving can be reduced). Further, since a large load is not applied to the conveyance belt 103 described later at the start of driving, the conveyance belt 103 can be prevented from being damaged.

  It should be noted that when the predetermined cleaning stop waiting time (tb) elapses from when the stopping condition for the lifting and cleaning operation is satisfied in this way, the lifting and cleaning drive is not stopped, for example, the lifting and cleaning device 25. A game ball detection sensor or the like is provided at the discharge port 38 to restrict the inflow of the game ball to the lifting and cleaning device 25, and then a new game ball is detected within a predetermined time after the detection sensor detects the game ball. The pumping / cleaning drive may be stopped on condition that it is no longer detected.

  Moreover, when performing the maintenance operation | work etc. of the lift cleaning apparatus 25, the lifting drive of the lift cleaning apparatus 25 can be manually stopped by performing a specific stop operation. However, even in this case, after restricting the inflow of the game ball to the lift cleaning device 25 by the shutter devices 200L and 200R, the lift cleaning drive of the lift cleaning device 25 is stopped when a predetermined period has elapsed.

  Further, the controller 220 for lifting and cleaning control starts measuring time by the stop period timer from when the proximity sensors 210L and 210R determine that the game balls are not detected for a predetermined time (for example, 10 seconds) and the proximity sensors 210L and 210R; off. The next time until the proximity sensor 210L, 210R continuously detects the game ball for a predetermined time (for example, 10 seconds) and determines that the proximity sensor 210L, 210R; on, that is, the lifting and cleaning operation is stopped. The current stop period (tc) is counted.

  Then, as shown in FIG. 9C, when the lifting and cleaning control controller 220 determines that the proximity sensors 210L and 210R; on, the time measured by the stop period timer (stop period: tc) When it is within the range of 0 to 30 seconds, it is a cleaning stop waiting time to be described later, and the movable plates 201L and 201R are in the closed position, but the lift cleaning motor 80 is driven, that is, lift cleaning. Since the operation is being executed, the cleaning start waiting time (ta) is not set (ta = 0 seconds), and the movable plate is moved via the shutter motors 202L and 202R on the side corresponding to the proximity sensor that immediately detects the game ball. 201L and 201R are moved from the closed position to the open position to place the shutter devices 200L and 200R in an allowable state, and the feeding and cleaning operation is continued.

  In the present embodiment, although not shown in detail in detail, the lifting and cleaning control controller 220 has a predetermined time (for example, 30 seconds) as a cleaning start waiting time (ta) in the startup process of the lifting and cleaning device 25. Therefore, when the proximity sensors 210L and 210R are first determined to be on after activation, when the cleaning start waiting time (ta) 30 seconds elapses, the shutter on the side corresponding to the proximity sensor is set. The movable plates 201L and 201R are moved from the closed position to the open position via the motors 202L and 202R to place the shutter devices 200L and 200R in an allowable state, and the feeding and cleaning operation is started.

  When the stop period (tc) is within the range of 31 to 120 seconds, 120 seconds are set as the cleaning start waiting time (ta), and 120 seconds have elapsed since the proximity sensors 210L and 210R; At this time, the movable plates 201L and 201R are moved from the closed position to the open position via the shutter motors 202L and 202R on the side corresponding to the proximity sensor that has detected the game ball, so that the shutter devices 200L and 200R are allowed. When the stop period (tc) is 121 seconds or longer, 180 seconds is set as the cleaning start waiting time (ta), and when 180 seconds have elapsed since the proximity sensors 210L and 210R; The movable plates 201L and 201R are moved from the closed position to the open position via the shutter motors 202L and 202R on the side corresponding to the proximity sensor that has detected the game ball, and the shutter devices 200L and 200R are allowed.

  That is, in this embodiment, when the start condition for the lift cleaning operation is established, the lift cleaning operation is started based on the elapse of a predetermined cleaning start waiting time (ta). ta) is changed according to the time from when the previous pump cleaning operation is stopped until a new pump cleaning start condition is satisfied, that is, a different cleaning start waiting time is set according to the stop period. The

  For example, if the time from when the lifting and cleaning operation is stopped until a predetermined amount or more of the game balls stay in the collection passage is short, that is, when there are many pachinko gaming machines 2 that are operating, the upper tank 3 is stored. A short time is set as the cleaning start waiting time so that the supply of gaming balls to the pachinko gaming machine 2 is not interrupted due to a decrease in the amount, so that the cleaning operation is started early. On the other hand, when the time from when the lifting and cleaning operation is stopped until a predetermined amount or more of the game balls stay in the collection passage, that is, when there are few pachinko gaming machines 2 in operation, the upper tank 3 is stored. The supply of gaming balls to the pachinko gaming machine 2 is not immediately interrupted and the cleaning start waiting time is set as a long time, so that the cleaning operation is started with a margin. It becomes possible to perform a clean operation efficiently according to the operating status.

  In this embodiment, when the stop period (tc) is within the range of 31 to 120 seconds, the cleaning start waiting time (ta) is changed (set) to 120 seconds and the stop period (tc) is 121 seconds. In the case of the above, the cleaning start waiting time (ta) is changed (set) to 180 seconds, but the present invention is not limited to this, and the stop period (tc) and the stop The cleaning start waiting time (ta) set according to the period (tc) may be set to a time other than the above.

  In this embodiment, the cleaning start waiting time (ta) is changed (set) to 120 seconds or 180 seconds according to the stop period (tc). It may be possible to change (set) to ta).

  In this embodiment, the timing of changing the shutter devices 200L and 200R corresponding to the proximity sensors 210L and 210R; off to the non-permissible state is the upstream side of the shutter devices 200L and 200R from the inflow port 37. The game ball is in a state of staying until. Specifically, when it is determined that the proximity sensors 210L and 210R are off, the proximity sensors 210L and 210R are movable so that the game ball is retained from the inlet 37 to the upstream side of the shutter devices 200L and 200R. The plates 201L and 201R are disposed at locations separated from the upstream side by the same distance L2.

  That is, after the driving of the lifting and cleaning device 25 is started, the collected game balls are not newly added, and the game balls staying from the inlet 37 to the proximity sensors 210L and 210R are stored in the shutter devices 200L and 200R. The time required to decrease to the vicinity of the upstream side is about 10 seconds or more, that is, the time required for the proximity sensors 210L and 210R to be determined to be off after the game balls are not detected by the proximity sensors 210L and 210R. What is necessary is just to set it as the distance L2 used as the time longer than second. In this way, when the movable plates 201L and 201R move from the open position to the closed position, game balls exist on the upstream side of the movable plates 201L and 201R. It can be prevented from colliding with 201R and being damaged.

  Next, the lifting and cleaning process executed by the lifting and cleaning control controller 220 will be described with reference to the flowchart of FIG. FIG. 10 is a flowchart showing the control content of the lifting and cleaning process executed by the lifting and cleaning control controller. The lift cleaning process is a process executed in the timer interruption process after the start-up process of the lift cleaning apparatus.

  First, the controller 220 for lifting and cleaning control determines whether or not the cleaning flag indicating that the lifting and cleaning motor 80 of the lifting and cleaning device 25 is driven and the cleaning and cleaning operation is being performed is set in the RAM 231. Is determined (step S101). If the cleaning flag is not set (step S101; No), the cleaning start waiting time (ta) from when it is determined that the start condition for the lift cleaning operation is satisfied until the lift cleaning operation is performed is determined. It is determined whether or not the cleaning start waiting flag shown is set (step S102).

  When the cleaning start waiting flag is not set (step S102; No), whether or not the proximity sensors 210L and 210R are on, that is, the game balls are continuously played for 10 seconds by the proximity sensors 210L and 210R. It is determined whether or not it has been detected (step S103). If the proximity sensors 210L and 210R are not on, it is assumed that the game balls to be lifted and cleaned by the lift and cleaning device 25 are not staying more than a predetermined amount from the connecting rods 10L and 10R to the flow-down grooves 9L and 9R. finish. Further, when the proximity sensors 210L and 210R are on, that is, when a game ball to be lifted and cleaned by the lift and cleaning device 25 is retained for a predetermined amount or more from the connecting rods 10L and 10R to the flow-down grooves 9L and 9R. (Step S103; Yes), the count value of the stop period timer is confirmed, and it is determined whether or not the value of the stop period timer is in the range of 31 to 120 seconds (step S104). When the value of the stop period timer is in the range of 31 to 120 seconds (step S104; Yes), a value corresponding to 120 seconds is set in the cleaning start waiting timer (step S105). If the value of the stop period timer is not in the range of 31 to 120 seconds (step S104; No), a value corresponding to 180 seconds is set in the cleaning start waiting timer (step S107). Then, after step S105 or step S107, a cleaning start waiting flag is set (step S106), and the process ends. When the value of the stop period timer is within 30 seconds, the cleaning stop waiting time described later is set and the cleaning flag is set, so that the processing of steps S128 to S130 described later is performed.

  When the cleaning start waiting flag is set (step S102; Yes), the cleaning start timer value is decremented by 1 (step S108), and whether the timer value of the cleaning start waiting timer has become 0, that is, proximity It is determined whether or not the time set in step S105 or step S107 has elapsed since it was determined that the sensors 210L and 210R; off (step S109). When the timer value of the cleaning start waiting timer is not 0 (step S109; No), it is determined that it is the cleaning start waiting time, and the process is ended as it is. When the timer value of the cleaning start waiting timer is 0 (step S109; Yes), the movable plates 201L and 201R are moved from the closed position to the open position (step S110), and the lift cleaning motor 80 is moved. It is driven to start the lifting and cleaning operation (step S111). Then, the cleaning start waiting flag is cleared (step S112), the cleaning flag is set (step S113), and the process ends.

  In addition, when the cleaning flag is set in step S101 (step S101; Yes), the cleaning stop waiting time from when it is determined that the stop condition for the pump cleaning operation is satisfied until the pump cleaning operation is stopped. It is determined whether or not a clean stop waiting flag indicating that it is (tb) is set (step S120). When the clean stop waiting flag is not set (step S120; No), whether or not the proximity sensors 210L and 210R are off, that is, the proximity balls 210L and 210R do not detect a game ball for 10 seconds, which is a predetermined time. If it is not the proximity sensors 210L and 210R; off (step S121; No), the process is terminated as it is. Further, when the proximity sensors 210L and 210R are off (step S121; Yes), the game balls to be lifted and cleaned by the lift and cleaning device 25 are more than a predetermined amount from the connecting rods 10L and 10R to the flow-down grooves 9L and 9R. The moving plates 201L and 201R are moved from the open position to the closed position assuming that they are not staying (step S122), and a value corresponding to 30 seconds, which is the clean stop waiting time, is set in the clean stop waiting timer value (step S123). ) After setting the clean stop waiting flag (step S124), the timer of the stop period timer is started (step S125), and the process ends.

  When the clean stop wait flag is set (step S120; Yes), the timer value of the clean stop wait timer is decremented by 1 (step S126), and it is determined whether the timer value of the clean stop wait timer has become 0. (Step S127). If the timer value of the clean stop waiting timer is not 0 (step S127; No), whether or not the proximity sensors 210L and 210R are on, that is, the proximity sensors 210L and 210R indicate that the game ball is a predetermined time 10 It is determined whether or not it has been detected continuously for a second (step S128). If the proximity sensors 210L and 210R are not on (step S128; No), a game ball to be lifted and cleaned by the lift cleaning device 25 is connected. The processing is terminated as it is, assuming that no more than a predetermined amount has accumulated from the troughs 10L, 10R to the downflow grooves 9L, 9R. Further, when the proximity sensors 210L and 210R are on, that is, when a game ball to be lifted and cleaned by the lift and cleaning device 25 is retained for a predetermined amount or more from the connecting rods 10L and 10R to the flow-down grooves 9L and 9R. (Step S128; Yes), since the cleaning stop waiting time is in progress, the value of the stop period timer is in the range of 0 to 30 seconds. Therefore, the movable plate can be moved without setting a predetermined time in the cleaning start waiting timer. 201L and 201R are moved from the closed position to the open position (step S129), the clean stop waiting flag is cleared (step S130), and the process ends. That is, in this case, the lifting and cleaning operation is continuously executed.

  Further, when the timer value of the cleaning stop waiting timer becomes 0 (step S127; Yes), the driving of the lifting cleaning motor 80 is stopped (step S131), and the lifting stop waiting flag and the cleaning flag are cleared. (Step S132), the process ends.

  Next, based on FIG.11 and FIG.12, an example of the collection | recovery state of the game ball accompanying a pump cleaning operation | movement is demonstrated. Here, the operation states of the lift cleaning device 25, the right shutter device 200R, and the proximity sensor 210R will be described, and the operation states of the left shutter device 200L and the proximity sensor 210L are the same, and the description thereof will be omitted.

  As shown in FIG. 11A, in the case where the shutter device 200R is in the non-permitted state, the game balls discharged from each pachinko gaming machine 2 fall into the flow down groove 9R, and from the flow down groove 9R. It flows down toward the connecting rod 10R and is collected. Then, in the connecting rod 10R, the flow is restricted by the movable plate 201R in the closed position, so that the game balls that are lifted and cleaned by the lifting and cleaning device 25 are transferred from the movable plate 201R of the connecting rod 10R to the flow-down groove 9R. It stays (waits) towards.

  Then, as shown in FIG. 11 (B), the game balls newly discharged from the pachinko gaming machine 2 stay one after another at the end of the game ball group. Then, when the tail of the staying game ball group reaches the vicinity of the proximity sensor 210R and the proximity sensor 210R determines that the game ball is detected continuously for a predetermined time of 10 seconds (proximity sensor 210R; on ), Assuming that a predetermined amount or more of the game balls to be lifted and cleaned by the lifting and cleaning device 25 are accumulated from the connecting rod 10R to the flow-down groove 9R, the proximity sensor 210R; When the time (ta) has elapsed, the movable plate 201R is moved from the closed position to the open position, and the lift cleaning motor 80 is driven to start the lift cleaning operation. Thereby, the game ball regulated and retained by the movable plate 201R is guided to the inflow port 37 and flows into the lifting and cleaning device 25 (see FIG. 11C).

  Further, by performing the lifting and cleaning operation, as shown in FIG. 12 (D), the game ball staying toward the flow-down groove 9R from the inlet 37 through the junction passage 11 and the connecting rod 10R is lifted. While there is a game ball that is discharged and collected from each pachinko machine 2 while being taken in and reduced by the feeding / cleaning device 25, if there is a game ball to be collected, it flows from the inlet 37 to the flow down groove 9 </ b> R via the junction passage 11 and the connecting rod 10 </ b> R. The situation where the game ball is staying towards continues. When the number of game balls taken into the lifting and cleaning device 25 exceeds the number of game balls discharged and collected from each pachinko gaming machine 2, the number of staying game balls decreases. If the number of game balls taken into the lifting and cleaning device 25 exceeds the number of game balls discharged from each pachinko gaming machine 2 and collected, the staying game balls are maintained or increased.

  Then, when the number of staying game balls decreases and the last of the staying game ball group moves away from the proximity sensor 210R, the proximity sensors 210L and 210R do not detect the game ball for a predetermined time of 10 seconds. As shown in FIG. 12 (E), it is assumed that the game balls to be lifted and cleaned by the lifting and cleaning device 25 do not stay more than a predetermined amount from the connecting rods 10L and 10R to the flow-down grooves 9L and 9R. 201R is moved from the open position to the closed position.

  As described above, the movable plate 201R is opened by setting the distance L2 so that the movable plate 201R is moved from the open position to the closed position with the game ball upstream of the shutter device 200R. Since there is no situation where there is no game ball on the upstream side when moving from the position to the closed position, the game ball flowing down the connecting rod 10R is prevented from directly colliding with the movable plate 201R.

  Then, if the proximity sensor 210R is determined to be off and the movable plate 201R is moved from the open position to the closed position, the proximity sensor 210R is not turned on again until 30 seconds, which is a cleaning stop waiting time, elapses. The drive of the lift cleaning motor 80 is stopped. Thereafter, the state returns to the state of FIG.

  Next, based on FIG.13 and FIG.14, an example of the start and stop condition of a pumping cleaning operation | movement is demonstrated. FIGS. 13A and 13B are timing charts showing the start timing of the lifting and cleaning operation when the stop period is 121 seconds or more, and FIG. 13B is the start timing of the lifting and cleaning operation when the stop period is 30 seconds to 120 seconds. FIG. 14 is a timing chart showing the start timing of the lifting and cleaning operation when the stop period is 0 to 30 seconds.

  As shown in FIG. 13A, for example, when it is determined that the proximity sensor 210R; on, counting by the cleaning start waiting timer is started from that point, and 30 seconds is set as the cleaning start waiting time (ta1). If the 30 seconds have elapsed, the movable plate 201R moves from the closed position to the open position, and the lift cleaning motor 80 is driven to start the lift cleaning operation.

  When it is determined that the proximity sensor 210R is off during the lifting and cleaning operation, the count by the clean stop waiting timer is started and the count (time count) by the stop period timer is started. Then, when 30 seconds, which is the cleaning stop waiting time (tb), has elapsed, the driving of the lifting and cleaning motor 80 is stopped, and the lifting and cleaning operation ends.

  Next, after it is determined that the proximity sensor 210R; off, and when it is determined that the proximity sensor 210R; on, the value of the stop period timer at that time is 121 seconds or more, that is, the previous proximity sensor 210R; off. 180 seconds are set as the cleaning start waiting time (ta2) when the time of 121 seconds or longer has elapsed since the determination was made. Therefore, when 180 seconds have passed since the proximity sensor 210R; on was determined, the movable plate 201R moves from the closed position to the open position, and the lift cleaning motor 80 is driven to start the lift cleaning operation. Is done.

  Further, as shown in FIG. 13B, when it is determined that the proximity sensor 210R; off is determined again after the proximity sensor 210R; off during the lifting and cleaning operation, the value of the stop period timer at that time is determined again. Is 31 seconds to 120 seconds, that is, when the time within 31 seconds to 120 seconds has elapsed since the time when the proximity sensor 210R; was determined to be off, the cleaning start waiting time (ta3) 120 seconds is set. Therefore, when 120 seconds have elapsed since it was determined that the proximity sensor 210R; on, the movable plate 201R moves from the closed position to the open position, and the lift cleaning motor 80 is driven to start the lift cleaning operation. Is done.

  Further, as shown in FIG. 14A, when the lifting and cleaning operation is executed based on the determination that the right proximity sensor 210R; on, for example, the left pachinko gaming machine 2 on the game island 1 When the number of game balls collected from the vehicle increases and it is determined that the left proximity sensor 210L; on, the value of the stop period timer at that time is within 30 seconds, that is, the previous proximity sensor 210R; off If the time within 30 seconds has elapsed from the time when it is determined, the right proximity sensor 210R; within the cleaning stop waiting time based on the determination that it is off, the right movable plate 201R is in the closed position. However, since the lift cleaning operation by the lift cleaning motor 80 is being executed, the cleaning start waiting time (ta4) is not set, and the left movable plate 201L moves from the closed position to the open position. Rutotomoni, pumped cleaning operation by the pumped cleaning motor 80 is continued.

  As described above, when it is determined that the proximity sensors 210L and 210R; on within the cleaning stop waiting time, that is, when the value of the stop period timer is within 30 seconds, the movable plates 201L and 201R in the closed position are moved. By moving immediately to the open position and continuing the lifting and cleaning operation, it is not necessary to perform useless control such as starting immediately after stopping the lifting and cleaning operation, Since it can be transported to the tank 3, it can be avoided that supply of game balls to the pachinko gaming machine 2 is interrupted.

  In this embodiment, as described above, when it is determined that the proximity sensors 210L and 210R; on within the clean stop waiting time, that is, when the value of the stop period timer is within 30 seconds, the closed position The movable plates 201L and 201R are immediately moved to the open position to continue the cleaning operation. However, a predetermined time (for example, 60 seconds) is set as a cleaning start waiting time, After stopping the feeding and cleaning operation, the lifting and cleaning operation may be newly started after the cleaning start waiting time elapses.

  As described above, in the gaming island 1 as an embodiment of the present invention, the collection baskets 17, 17 as the collection passages for collecting the gaming balls discharged from the plurality of pachinko gaming machines 2 installed, the guide basket 19, the downflow grooves 9L and 9R, the connecting rods 10L and 10R, the merging passage 11, and the lift cleaning device 25 for cleaning the game balls collected in these recovery passages. , Whether or not the proximity sensors 210L and 210R are turned on in step S103 in the lifting and cleaning process shown in FIG. 10, that is, the game balls to be lifted and cleaned by the lifting and cleaning device 25 flow down from the connection rods 10L and 10R. It is determined whether or not a predetermined amount or more is accumulated over the grooves 9L and 9R, and the proximity sensors 210L and 210R are turned on in step S103 in the lifting and cleaning process shown in FIG. When it is determined in step S109 that the timer value of the cleaning start waiting timer has reached 0, the movable plates 201L and 201R are moved to the open position to drive the lift cleaning motor. In step S121, After determining that the proximity sensors 210L and 210R have been turned off, when it is determined in step S127 that the timer value of the cleaning stop waiting timer has reached 0, the movable plates 201L and 201R are moved to the closed position to move the lift cleaning motor. Stop. Further, when it is determined that the proximity sensors 210L and 210R; are turned off in step S121 in the lifting and cleaning process shown in FIG. 10, the lifting and cleaning control controller 220 starts the stop period timer in step S125 and measures the time. When it is determined that the proximity sensors 210L and 210R are turned on in step S103 in the lifting and cleaning process shown in FIG. 10, when the value of the stop period timer is between 31 and 120 seconds in step S104, step S105 is performed. At 120, the cleaning start waiting timer is set to 120 seconds. When the stop period timer value is not between 31 to 120 seconds at step S104, the cleaning start waiting timer is set to 180 seconds at step S107, and at step S128. Proximity sensors 210L, 210R; When was boss moves the movable plate 201L without setting a value to the cleaning start wait timer, the 201R in an open position.

  In this way, when it is determined that a predetermined amount or more of game balls are staying in the collection passage, the lifting and cleaning operation is started, and it is determined that a predetermined amount or more of game balls is not staying in the collection passage. Since the lifting and cleaning operation is stopped when the operation is performed, that is, the lifting and cleaning device 25 can be intermittently driven, the lifting and cleaning operation is performed, for example, although there are few game balls to be lifted and cleaned. Execution is prevented.

  In addition, when the time from when the lifting and cleaning operation is stopped to when a predetermined amount or more of the game balls stay in the collection passage is short, that is, when there are many pachinko gaming machines 2 that are operating, the lifting and cleaning operation is performed faster. The pachinko gaming machine is started, and when the time until a predetermined amount or more of the game balls stay in the collecting passage is long, that is, when there are few pachinko gaming machines 2 in operation, the lifting and cleaning operation is started with a margin. It is possible to efficiently perform the lifting and cleaning operation according to the operation status of 2.

  Further, in the present embodiment, the proximity sensors 210L and 210R as detection means for detecting the game balls staying in the flow down grooves 9L and 9R, the connecting rods 10L and 10R, and the merge passage 11, and the lifting and purifying device 25 are close to each other. Shutter devices 200L and 200R, which are provided between the sensors 210L and 210R, and are movable means capable of changing between an allowable state allowing the inflow of game balls to the lifting and cleaning device 25 and a non-permissible state not allowed. The lift cleaning controller 220 determines whether or not the proximity sensors 210L and 210R are turned on in step S103 in the lifting and cleaning process shown in FIG. 10, and the proximity sensors 210L and 210R are determined in step S121. When it is determined that the shutter has been turned off, the shutter devices 200L and 200R are changed to the non-permitted state in step S122. In step S123, a value corresponding to 30 seconds is set in the cleaning stop waiting timer. After that, in step S127, when it is determined that the value of the cleaning stop waiting timer has become 0, the pump cleaning is performed in step S131. The motor 80 is stopped.

  By doing so, it is possible to prevent the lifting and cleaning operation from being stopped while the gaming ball remains in the lifting and cleaning device 25, and the gaming ball can be moved when the shutter devices 200L and 200R are in the non-permitted state. Direct collision with the movable plates 201L and 201R of the shutter devices 200L and 200R can be prevented.

  Further, in this embodiment, by including an inverter 240 for converting power to be supplied to the lifting and purifying device 25 from DC power to AC power, and a metal box 241 made of metal surrounding the inverter 240, It can be avoided that noise generated by using the inverter 240 affects peripheral devices (for example, the controller 220 for lifting and cleaning control, proximity sensors 210L and 210R, various electronic devices of the pachinko gaming machine 2, and the like).

  In the present embodiment, as an example of the cleaning device of the present invention, a lifting and cleaning device 25 that cleans the game balls collected in the lower part of the gaming island 1 while lifting them to the upper tank 3 in the upper part of the gaming island 1. However, the present invention is not limited to this, and the present invention may be applied to a cleaning device having only a cleaning function without transporting the game ball to the upper part of the game island 1. Specifically, for example, a cleaning device to which the present invention is applied may be disposed in a part of the game ball flow path disposed in the game island 1 separately from the lifting device.

  In the present embodiment, when it is determined that the proximity sensors 210L and 210R are off, the driving of the lift cleaning motor 80 is stopped after a predetermined cleaning stop waiting time has elapsed. Is not limited to this, and when it is determined that the proximity sensors 210L and 210R; off, the driving of the lift cleaning motor 80 is immediately stopped without waiting for the elapse of a predetermined cleaning stop waiting time. May be.

  Further, in this embodiment, after the lift cleaning operation is started based on the determination that the proximity sensors 210L and 210R; on, the lift cleaning is performed based on the determination that the proximity sensors 210L and 210R; off. Although the operation stop condition is established, the present invention is not limited to this, and the condition for stopping the lift cleaning operation is established after a predetermined time has elapsed since the start of the lift cleaning operation. It may be.

  Further, in the present embodiment, in the lifting and cleaning process shown in FIG. 10, based on the determination that the proximity sensors 210L, 210R; However, the present invention is not limited to this, and when it is determined in step S121 that the proximity sensors 210L and 210R; off, only the processing of steps S122 to S124 is executed, and in step S131. Based on the fact that the driving of the lift cleaning motor 80 is stopped, the time measurement by the stop period timer may be started.

  FIG. 15 shows an example of the lifting and cleaning process as a modification of the present invention.

  In the above-described embodiment, based on the determination that the proximity sensors 210L and 210R; off in step S121 in the lifting and cleaning process shown in FIG. 10, the time measurement by the stop period timer is started in step S125. However, the present invention is not limited to this. As shown in FIG. 15, when it is determined in step S103 that the proximity sensors 210L and 210R; on, the processes in steps S104 to 107 are performed. In step S106a, the cleaning start waiting time setting timer may be reset, and the time measurement by the cleaning start waiting time setting timer may be started. In this case, in step S104a, it may be determined whether or not the timer value of the cleaning start waiting time setting timer is 200 to 300 seconds.

  In such a case, based on the determination that the proximity sensors 210L and 210R; on in step S103, the lift cleaning operation is started in step S111, and after the lift cleaning operation is stopped, Next time, when it is determined in step S103 that the proximity sensors 210L and 210R; on, the time from when the previous proximity sensors 210L and 210R; on are determined until the current proximity sensors 210L and 210R; on is determined. Accordingly, the cleaning start waiting time is set (changed) in step S105 or step S107.

  That is, according to the present invention, the time from when it is determined that the proximity sensors 210L and 210R; off to the next time when the proximity sensors 210L and 210R; The present invention is not limited to setting (changing) the cleaning start waiting time according to the stopped time. As in the present modification, the proximity sensor 210L, 210R; 210L, 210R; time until it is determined to be on, that is, the cleaning start waiting time according to the sum of the period in which the previous pump cleaning operation was executed and the period in which the pump cleaning operation was stopped thereafter May be set (changed).

  Also, in the case of this modification, when it is determined in step S103 that the proximity sensors 210L and 210R are on, the time measurement by the cleaning start waiting time setting timer is newly started in step S106a. In step S103, it is determined that the proximity sensors 210L and 210R are turned on, and based on the fact that the driving of the lift cleaning motor 80 is started in step S111, the time measurement by the cleaning start waiting time setting timer is started. You may make it do.

  In the present embodiment, the shutters 200L and 200R are provided on the connecting rods 10L and 10R. However, the present invention is not limited to this, and the connecting rods 10L and 10R are not limited to this, and are arranged in other collection passages such as the downflow grooves 9L and 9R. Such shutter devices 200L and 200R may not be provided. Further, like the shutter devices 200L and 200R of the present embodiment, the shutter devices are not limited to those provided at two locations corresponding to the connecting rods 10L and 10R. For example, as a modified example described below As in the shutter device 500, only one may be provided in front of the inlet 37 in the merge passage 11.

  Next, a shutter device 500 as a modification of the present invention will be described with reference to FIGS. FIG. 16: is a principal part expanded sectional view which shows the lower structure of the pumping cleaning apparatus as a modification. FIG. 17 is a perspective view illustrating a state in which a shutter device as a modification is viewed obliquely from behind.

FIGS. 22A and 22B show the positional relationship between the movable passage member and the connection port in the inflow position, and FIG. 22B in the closed position. FIG. 23 is a schematic diagram illustrating a flow regulation state by a shutter device as a modified example. Since the lift cleaning device is the same as the lift cleaning device 25 of the above embodiment, the description of the same parts is omitted, and only the shutter device is described. Note that the shutter devices 200L and 200R described in the above embodiments are not necessary.

  As shown in FIGS. 17 to 21, the shutter device 500 mainly includes a main unit 501 fixed on the base plate 110 and a drive unit 502 provided on the upper portion of the main unit 501. The main body unit 501 is formed in a box shape whose rear side is opened by metallic left and right side plates 504L and 504R and a rear plate 503, and a swing passage member 551 and a snorkel rail 552 that constitute a merge passage 550 are provided inside. ing.

  At the upper positions of the left and right side plates 504L and 504R, connection ports 505L and 505R having a horizontally long rectangular shape are formed, and connection rods 10L and 10R are connected to the connection ports 505L and 505R.

  A connection port 506 is formed in the upper part of the rear plate 503, and a connection rod 508 for coupling a crossover rod 507 connected to a storage tank of another game island (not shown) is connected to the connection port 506. It is attached to protrude toward the direction. The connection port 506 has substantially the same shape as the connection ports 505L and 505R, and at least the lower sides of the connection ports 506 are formed at substantially the same height.

  As shown in FIGS. 19 to 22, the swing passage member 551 includes a passage plate portion 560 having a substantially square shape in plan view, a front plate portion 561 bent upward from the front side of the passage plate portion 560, The upper plate portion 562 bent backward from the upper side of the plate portion 561 is formed in a substantially U shape in a side view.

  The passage plate portion 560 is disposed so that three sides are close to the inner surfaces of the left and right side plates 504L and 504R and the rear plate 503. The left right side is formed slightly longer than the lower side of the connection ports 505L and 505R, and the rear side is formed slightly longer than the lower side of the connection port 506. Further, a plurality of circular drop holes 563 having a diameter of about 20 mm are formed from approximately the center in the front-rear direction of the passage plate portion 560 to the rear side. Therefore, the game ball that has flowed onto the passage plate portion 560 falls from the drop hole 563 and is allowed to flow into the lifting and cleaning device 25. For example, a large foreign object such as a prepaid card used for lending game balls It is captured and entry into the lifting and cleaning device 25 is prevented.

  In addition, from the left and right sides and the rear side of the passage plate portion 560, horizontally-long rectangular regulating pieces 564L, 564R, and 564B are bent downwardly, respectively. The vertical width dimensions of these restricting pieces 564L, 564R, 564B are longer than the diameter 2R of the game ball.

  As described above, the passage plate portion 560 constituting a part of the junction passage 550 includes the connection ports 505L and 505R to which the connection rods 10L and 10R, which are recovery passages, are connected, and the connection port 506 to which the crossover rod 507 is connected. Restriction pieces 564L, 564R, 564B are formed at positions corresponding to. In addition, the passage plate portion 560 corresponds to the joining portion (the joining rods 10L and 10R in the joining passage 550) where the game balls of the plurality of collection passages join, such as the connecting rods 10L and 10R and the transition rod 507 in the joining passage 550. The connection ports 505L and 505R and the portion surrounded by the connection port 506 corresponding to the crossover 507) are provided.

  Bearing pieces 565L and 565R are formed to be bent forward on the left and right sides of the front plate portion 561. The bearing pieces 565L and 565R have a notch formed in a notch from the lower end to the upper side, and the engaging groove 566 protrudes inwardly at a predetermined height position of the left and right side plates 504L and 504R. It is latched from above by rotating shafts 567L and 567R, which are made of fixed bolts and face in the left-right direction. Thus, the swing passage member 551 is provided so as to be swingable in the vertical direction around the rotation shafts 567L and 567R facing in the left-right direction.

  The upper plate portion 562 is disposed near the upper portion of the connection ports 505L and 505R, and a substantially square inspection port 570 is formed. Since the inspection port 570 is closed by a cover plate 571 made of a light-transmitting synthetic resin plate, the inspection port 570 is prevented from falling foreign matter or dust into the lower junction passage 550, and the inspection port The inside of the merging passage 550 can be inspected from 570 through the lid plate 571. Further, by opening the cover plate 571, it is possible to approach the junction passage 550 from the inspection port 570, and therefore, when dust or the like enters, it can be taken out from the inspection port 570.

  Further, a connecting shaft 573 facing in the left-right direction is provided at the rear end portion of the upper surface of the upper plate portion 562, and the upper end pivotally supports the lower end of the link member 574 connected to the drive unit 502.

  At the lower position of the swing passage member 551, a snowboard rail 552 is provided so as to be inclined downward from the rear side toward the front side, and the lower end is connected to the ball introduction passage 123. As shown in FIG. 21 in particular, the snowboard rail 552 is disposed between the eight side wall rails 552a forming the side surface of the game ball flow-down passage and the side wall rails 552a, and constitutes the bottom surface of the game ball flow-down passage. 7 bottom wall rails 552b and a base body 552c that integrates the side wall rails 552a and the bottom wall rails 552b, and seven rows of downflow passages 135 are formed.

  Therefore, the game ball that has fallen from the drop hole 563 flows down the snowboard rail 552 and flows into the ball introduction passage 123. Further, the foreign matter that has passed through the drop hole 563 and dropped onto the snocorail 552 falls into the space S provided below from the gap of the snocorail 552, so that the foreign matter can be removed from the space S.

  The diameter of the drop hole 563 is set to a size that allows an appropriate amount of the game ball flowing into the junction passage 550 to be dropped on the snorkel rail 552 below it. In this way, by suppressing the outflow amount of the game ball onto the snocorail 552, a large amount of game spheres flow into and fill the snocorail 552 and the ball introduction passage 123 on the downstream side thereof, so that the inlet 37 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 lifting and cleaning motor (not shown) that drives the lower roller 102 to rotate.

  As shown in FIGS. 19 to 21, the drive unit 502 is fixed on a top plate 576 provided on the upper part of the main unit 501. Specifically, the elevating motor 580, the elevating rod 581 that is supported on the back side of the elevating motor 580 so as to be pivotable around the axis, and the driving force of the elevating motor 580 are transmitted to the elevating rod 581. A gear box 582 in which a gear (not shown) is built in, a lifting body 583 that can be moved up and down on the lifting rod 581, and a pair of left and right guides that are provided side by side with the lifting rod 581 and guide the lifting body 583 up and down. The rod 584 is mainly composed of.

  The elevating body 583 has a female screw portion 583a that can be screwed into a male screw portion formed on the outer periphery of the elevating rod 581, and is screwed into the outer periphery of the elevating rod 581 through the female screw portion 583a. The rotation about the elevating rod 581 is restricted by being inserted into the guide rod 584 so as to be slidable in the longitudinal direction.

  An upper end of the link member 574 is pivotally supported on the elevating body 583 via a rotation shaft 575 that faces in the left-right direction. Further, a detection piece 585 protrudes on the left side, and when the lifting body 583 is in the upper position, the detection piece of the upper limit sensor 586a is pressed, and when it is in the lower position, the detection piece of the lower limit sensor 586b is pressed. To do.

  Further, on the front side of the lifting motor 580, a lifting board 587 to which the lifting motor 580, the upper limit sensor 586a, and the lower limit sensor 586b are connected is disposed. The lift board 587 is connected to the lift cleaning board 221 and drive control of the lift motor 580 is performed based on a command from the lift cleaning control controller 220 and detection results of the upper limit sensor 586a and the lower limit sensor 586b. It is like that. In addition, a manual switch 588 (see FIGS. 17 and 18) that can manually drive and stop the lifting motor 580 is provided on the top of the drive unit 502.

  The elevating body 583 is provided so as to be movable in the vertical direction between a lower limit position where the detection piece 585 is detected by the lower limit sensor 586b and an upper limit position where the detection piece 585 is detected by the upper limit sensor 586a. Then, the driving force of the elevating motor 580 is transmitted to the elevating rod 581 via the gear box 582, and the elevating rod 581 is rotated about the axis so that the guide rod 584 rotates about the elevating rod 581. The elevating body 583 in which the movement is restricted moves upward or downward.

  As the elevating body 583 moves up and down in this way, the rear end of the swing passage member 551 is raised or lowered via the link member 574, so that the rear end side is moved up and down around the rotation shafts 567L and 567R. Rocks.

  Specifically, when the elevating body 583 is in the lower limit position, the swing passage member 551 includes the passage plate portion 560 and the restriction pieces 564L, 564R, 564B below the lower sides 505a of the connection ports 505L, 505R, 506. The inflow position is located in a state slightly inclined in the front-rear direction with respect to the lower side 505a (see FIG. 22A).

  That is, at this inflow position, the passage plate 560 is positioned below the connection rods 10L and 10R connected to the connection ports 505L and 505R, and the regulation pieces 564L, 564R and 564B are also below the connection rods 10L and 10R. Since it is retracted, inflow of game balls from the connection ports 505L and 505R is allowed to flow into the passage plate portion 560.

  When the elevating body 583 is in the lower limit position, the swing passage member 551 has the passage plate portion 560 and the restriction pieces 564L, 564R, 564B on the lower side 505a below the lower sides 505a of the connection ports 505L, 505R, 506. On the other hand, the inflow position is located in a slightly inclined state in the front-rear direction (see FIG. 22A).

  That is, in this inflow position, the passage plate portion 560 is positioned below the connection rods 10L and 10R connected to the connection ports 505L and 505R, and the regulation pieces 564L, 564R and 564B are downward from the connection rods 10L and 10R. Since it is retracted, the game balls of the connecting rods 10L and 10R can flow into the passage plate portion 560 via the connection ports 505L and 505R.

  When the lifting body 583 is in the upper limit position, the swing passage member 551 is inclined in the front-rear direction with respect to the lower side 505a so that the passage plate portion 560 is above the lower side 505a of each connection port 505L, 505R, 506. In addition to being positioned in a state, a part of the restricting pieces 564L, 564R, 564B is in a closed position that closes a gap formed between the passage plate portion 560 and the lower side 505a (see FIG. 22B).

  That is, in this closed position, the passage plate portion 560 is located above the connection rods 10L and 10R connected to the connection ports 505L and 505R, and the regulation pieces 564L, 564R and 564B are on the bottom plates of the connection rods 10L and 10R. Since it has advanced, it becomes difficult for the game balls of the connection rods 10L and 10R to flow into the passage plate portion 560 via the connection ports 505L and 505R.

  As described above, the swing passage member 551 provided so as to be swingable between the inflow position and the closed position is provided for the junction passage 550 that connects the connection rods 10L and 10R as the recovery passage and the pumping cleaning device 25. It has a passage plate part 560 constituting a part. That is, the passage plate portion 560 constituting a part of the merge passage 550 is provided so as to be movable in the vertical direction with respect to the connection rods 10L and 10R, so that a part of the merge passage 550 is blocked (downflow) at the closed position. Regulation).

  The lifting and purifying device 25 flows down the connecting rods 10L and 10R, then joins in the joining passage 550, passes through the drop hole 563 of the passage plate portion 560, falls onto the snowboard rail 552, and passes through the ball introduction passage 123. The game balls that have been guided and flowed into the interior through the inlet 37 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 cleaned while being cleaned by the cleaning cloth 116. And can be discharged from a discharge port 38 provided in the upper part of the main body 100.

  Next, the operation of the shutter device 500 configured as described above will be described with reference to FIG. In the following description, the inflow state of game balls at the connection ports 505L and 505R will be mainly described, and the connection port 506 will be described later.

  First, when the game ball is lifted to the upper tank 3 by the lift cleaning device 25, the swing passage member 551 is located at the inflow position. That is, the passage plate portion 560 is positioned below the connecting rods 10L and 10R, and the restricting pieces 564L, 564R, and 564B are retracted downward from the connecting rods 10L and 10R, and thus have flowed down the connecting rods 10L and 10R. The game ball falls from the connection ports 505L and 505R and flows onto the passage plate portion 560 (see FIG. 23A).

  The game ball that has fallen on the passage plate portion 560 falls from the drop hole 563 onto the snowboard rail 552 while flowing down from the rear side to the front side, and then flows down on the snowboard rail 552 and is lifted through the inlet 37. It is guided to the inside of the feeding / cleaning device 25.

  Next, when the swing passage member 551 starts swinging to the closed position in order to stop the pumping to the upper tank 3, the passage plate portion 560 swings about the rotation shafts 567L and 567R. As a result, the front end (the end opposite to the rotation shafts 567L and 567R) of the left and right sides of the passage plate 560 is connected to the connection port 505L before the rear end (the rotation shafts 567L and 567R side). It reaches the lower side 505a of 505R and gradually rises from the front end side toward the rear end side.

  In addition, the restriction pieces 564L and 564R rise together with the left and right sides of the passage plate portion 560, and the regions between the left and right sides of the passage plate portion 560 and the lower side 505a in the connection ports 505L and 505R are closed. The falling of the game ball from the region to the snowboard rail 552 is restricted. That is, the wall part which regulates the outflow of the game ball is erected in the width direction at the connection end part of the connection rods 10L and 10R (see FIG. 23B).

  As described above, the swing passage member 551 is provided so as to be swingable about the rotation shafts 567L and 567R, so that the passage plate portion 560 is directed from one end side to the other end side in the longitudinal direction of the lower side 505a. Thus, it gradually protrudes upward, that is, gradually advances from below the connecting rods 10L, 10R in the width direction of the passage. Therefore, the game balls whose flow is blocked by the rising restricting pieces 564L and 564R can move in the width direction of the passage and are not blocked simultaneously in the width direction of the passage, and therefore the passage plate portion 560 in the width direction of the passage. As compared with the case where the motors are lifted all at once, an excessive load is hardly applied to the lifting motor 580.

  Further, the inflow is regulated from the front side of the connection ports 505L and 505R, and the passage plate portion 560 is tilted to the rear side, so that the game ball can only flow into the rear side of the passage plate portion 560. Go. And since the drop hole 530 is not formed on the rear side of the passage plate portion 560, the game ball is stored to some extent, and the overflowed game ball mainly falls from the drop hole 530 at the substantially central position in the front-rear direction. The amount of inflow into the snorkel rail 522 gradually decreases (see FIG. 23B).

  When in the closed position, the passage plate portion 560 is positioned above the lower side 505a except for a part on the rear side, and the left and right sides of the passage plate portion 560 at the connection ports 505L and 505R by the restriction pieces 564L and 564R. Since the region between the lower side 505a and the lower side 505a is closed, the inflow from the connecting rods 10L and 10R to the passage plate portion 560 is substantially restricted.

  Although there is a slight area where game balls can flow into the passage plate portion 560 on the rear side of the connection ports 505L and 505R, the tilt toward the rear side of the passage plate portion 560 becomes large, and the central drop hole 530 is located on the lower side. Since it is above 505a, the game ball at the rear of the passage plate portion 560 rides on the passage plate portion 560 from the drop hole 530 unless a large ball pressure is applied to the following balls from the connecting rods 10L and 10R. There is no overflow (see FIG. 23C).

  In addition, by restricting all the game balls flowing in from the left and right facing positions of the passage plate portion 560 by the restriction pieces 564L and 564R, it is possible to allow a part of the game balls to flow into the passage plate portion 560. Since the game balls of the left and right connecting rods 10L and 10R receive the ball pressure in each other's passage on the upper surface, the ball pressure applied to the regulating pieces 564L and 564R is reduced. Is done.

  Further, when descending from the closed position to the inflow position, although not described in detail, an operation reverse to that in the case of ascending from the inflow position to the closed position is performed. In this case, the inflow regulation of the game balls is released little by little as the swing passage member 551 is lowered, so that the game balls that have been dammed flow into the lift cleaning device 25 all at once, and the balls are clogged. There is no such thing.

  In addition, in the connection port 506, as shown in FIG. 20, the passage plate portion 560 and the restriction piece 564B are located below the lower side of the connection port 506 at the inflow position. 560 can flow into. On the other hand, in the closed position, the passage plate portion 560 is substantially at the same height as the lower side of the connection port 506, and the restriction piece 564B advances upward from the lower side. Inflow is regulated.

  Further, since the connection port 506 is provided in parallel to the rotation shafts 567L and 567R, when the swing path member 551 swings from the inflow position to the closed position, the restriction piece 564B is connected to the connection port 506. Since it rises all at once in the left-right width direction, it is possible to quickly regulate the flow down.

  As described above, in the shutter device 500 according to this modification, the game balls of the connection rods 10L and 10R have the passage plate portion 560 connected to the connection rod 10L when the swing passage member 551 is in the inflow position. , 10R and the restricting pieces 564L, 564R are retracted, so that they can flow into the passage plate portion 560. Further, when the swing passage member 551 is in the closed position, the passage plate portion 560 is positioned above the connecting rods 10L and 10R, so that the flow into the passage plate portion 560 becomes difficult or impossible, and the restriction piece 564L and 564R advance to the connecting rods 10L and 10R to prevent the flow into the passage plate portion 560.

  Further, by providing the swing passage member 551 at the junction, the restriction pieces 564L and 564R corresponding to the connecting rods 10L and 10R can be integrally provided on the passage plate portion 560, whereby the swing passage member 551 Since the plurality of restriction pieces 564L and 564R move at the same time according to the movement and the flow of game balls from the plurality of connection rods 10L and 10R can be restricted, the restriction pieces 564L and 564R are displaced for each connection rod 10L and 10R. Not only need to be provided as possible, but also a plurality of restriction pieces 564L, 564R can be interlocked using a passage member constituting the passage, so the number of parts is reduced, the structure is simplified, and the manufacturing cost is reduced. be able to.

  Further, since the restricting pieces 564L and 564R are formed integrally with the passage plate portion 560 by bending downward from the periphery of the passage plate portion 560 made of a plate-like member, the game balls of the connection rods 10L and 10R Even if a ball pressure is applied, the entire swinging passage member 551 can receive the ball pressure, and thus can be regulated stably.

  Further, by using the passage plate portion 560 to link the plurality of restricting pieces 564L, 564R, and 564B, an interlocking member that interlocks the plurality of restricting pieces 564L, 564R, and 564B is unnecessary, thereby reducing the number of parts. In addition, it is possible to simultaneously restrict the inflow of game balls from a plurality of recovery passages with a single shutter device at the junction without providing a shutter device in each recovery passage as in the prior art.

  Further, the shutter device 500 of the present modified example is provided with a movable passage member that can be displaced between an inflow position and a closed position at a joining portion where game balls from a plurality of collection passages join, Since the movable path member can be moved up and down simply by connecting the movable path member by providing the drive unit 502 on the upper part, it is also possible to easily provide a shutter device for the lift and cleaning device installed on the existing game island. Can do.

  Further, in the shutter device 500 of this modification, the main body unit 501 having the merging passage 550 and the drive unit 502 that swings the swing passage member 551 are each unitized. A product in which the drive unit 502 is assembled to the main unit 501 can be delivered, and if the shutter device 500 is not required, only the main unit 501 is delivered as a product, that is, with specifications corresponding to the amusement island of the amusement store. Since a product can be provided, and it is not necessary to prepare a plurality of types of products in advance, the manufacturing cost can be reduced.

  Further, the restricting pieces 564L, 564R, 564B are configured by wall portions that are continuously provided downward from positions corresponding to the connection rods 10L, 10R and the crossing rods 507 at the periphery of the passage plate portion 560. When the swing passage member 551 is raised, the restriction pieces 564L, 564R, 564B are raised from below to restrict the outflow of the game balls from the connection rods 10L, 10R and the transition rod 507, so that the junction passage 550 and the connection rod 550 are connected. It is possible to prevent the game ball at the connection position with 10L, 10R and the crossing rod 507 from being sandwiched between the restricting pieces 564L, 564R, 564B.

  In this modification, a restricting portion that is provided at a position corresponding to the connecting rods 10L and 10R on the periphery of the passage plate portion 560 and restricts the inflow of game balls from the connecting rods 10L and 10R to the passage plate portion 560. Is constituted by the restriction pieces 564L and 564R formed by bending the peripheral edge of the plate-like member. For example, the rocking passage member 551 is constituted by a thick plate member, and the upper surface thereof is formed as a passage portion. The side end surface may be the restricting portion.

  In addition, as long as the flow of the game ball can be regulated by contact, the game ball is not limited to the one constituted by the wall portions such as the regulating pieces 564L and 564R, and other members such as a net-like member, a fence-like member, a thread-like member, etc. You may be comprised with the member of.

  Further, the swing passage member 551 is provided on one end side in the width direction of the connecting rods 10L and 10R so as to be swingable about rotation shafts 567L and 567R provided in a direction substantially orthogonal to the width direction. Therefore, when moving toward the closed position, the game gradually advances from one end side to the other end side in the width direction of the connection rods 10L and 10R. Since the sphere is gradually regulated or released, an excessive load is hardly applied to the lifting motor 580 as compared with the case where the balls are advanced all at once in the width direction.

  Further, since the rotation shafts 567L and 567R are provided at positions separated from the connection rods 10L and 10R in the width direction, the passage plate portion 560 is connected to the connection rods 10L and 10R over the width direction of the connection rods 10L and 10R. Since it can be made to advance to, it is possible to reliably regulate the inflow of game balls.

  In this modification, the swing passage member 551 is swung. However, for example, as shown in FIG. 24, the inflow position is substantially parallel to the connecting rods 10L and 10R (see the solid line position in FIG. 24). Support means for supporting linear movement (up-and-down movement) between the closed position (refer to the position of the two-dot chain line in FIG. 24) may be provided.

  Specifically, the support means is fixed to the front surface of the guide bar 590 that is fixed to the main unit 501 and that faces the vertical direction and the front plate portion 561 of the swing passage member 551, and is attached to the guide bar 590. And a cylindrical member 591 as a guided portion that is slidably inserted. These support means are preferably provided at a plurality of locations of the swing passage member 551. Similarly to the above-described embodiment, the driving means may be configured by the lifting motor 580, the lifting rod 581, the gear box 582, the lifting body 583, the link member 574, and the control device.

  In this case, when the swing passage member 551 moves to the closed position or the inflow position, the swing ball member 551 advances or retreats all over the width direction of the connection rods 10L and 10R, so that the game balls of the connection rods 10L and 10R are simultaneously regulated. Or since it can cancel | release, a game ball can be controlled or cancel | released rapidly. Moreover, since it is supported by the support means, it can be stably moved even when the ball pressure from the recovery passage is applied to the restricting portion.

  Further, in the case of being provided so as to be movable up and down as described above, the passage plate portion 560 may be moved up and down while being tilted in the front-rear direction instead of being leveled.

  Further, since the shutter device 500 of the present embodiment is disposed on the opposite side of the linear passage cover 104 in the lifting and cleaning device 25 (see FIG. 4), the cleaning cloth 116 of the lifting and cleaning device 25 is replaced. There is no obstacle to maintenance work.

  Further, the swing passage member 551 of the present modification is disposed so as to incline downward from the front side toward the rear side at the inflow position, and the game balls flowing in from the connection rods 10L, 10R flow down toward the rear side. In addition, it is configured to drop downward from the plurality of drop holes 563, but if the game ball that has flowed in from the connection rods 10L and 10R can flow into the lifting and purifying device 25, it is like this. It is not limited to what is dropped downward from the plurality of drop holes 563. For example, the game ball may be dropped downward from the rear end after flowing down the game ball toward the rear side. Furthermore, it does not need to be comprised with the above plate-shaped members, for example, it may be comprised with rail members like the snowboard rail 552.

  In addition, the junction passage 550 is formed in a generally U shape by the passage plate portion 560 of the swing passage member 551 and the slat rail 552, but allows the game ball to flow into the lift cleaning device 25. If it is a channel | path, the flow-down form can be changed variously, and it may be comprised only by the channel | path board part 560.

  Moreover, in this modification, as an example of the recovery passage, the connection rods 10L and 10R and the crossover rod 507 connected to the left and right sides of the junction portion are configured. However, the movable passage is provided at a location where four or more passages merge. A member may be provided.

  In the present modification, the shutter device 500 is described as a device that constitutes a part of the lift cleaning device 25, but may be configured as a separate device from the lift cleaning device 25.

  FIG. 25 is a diagram showing a structure of a paper pipe 1110 of a lifting pipe that is applied to, for example, a part of the linear passage 115 in the lifting and cleaning device 25 or the inside of the discharge cover 120 and constitutes a part of the lifting path. It is. FIG. 25A is a perspective view of the paper pipe 1110. FIG. 25B is a cross-sectional perspective view of the paper pipe 1110.

  Referring to FIGS. 25A and 25B, a paper pipe 1110 includes a cylindrical body 1112 serving as a base of the paper pipe 1110 and a polymer resin layer 1111 formed inside the cylindrical body 1112. Have. A game ball P flows inside the paper pipe 1110.

  The game ball P has a diameter of 11 mm. The cylinder 1112 has a thickness of 1 mm and an inner diameter of 12 mm. The polymer resin layer 1111 is formed by spirally winding a strip having a width of 3 cm and a thickness of 30 μm. Moreover, the edges of adjacent strips are overlapped. In the present embodiment, the overlap width is 0.3 mm. The polymer resin layer 1111 is attached to the inside of the cylindrical body 1112 with an adhesive.

  The dirt of the game ball P can be removed from the surface of the polymer resin layer 1111 and the stepped portion where the strips overlap. The removed dirt accumulates in the stepped portion where the strips overlap. Further, the dirt of the game ball P can be further removed by the adsorbing power of the accumulated dirt. This is presumably because the suction force between the dirts is stronger than the suction force between the game ball P and the dirt. Thereby, the dirt accumulated in the step portion can be removed from the game ball P.

  Note that the dimensions of each part may be other dimensions as long as the flow of the game ball P is not hindered. For example, when the inner diameter of the cylindrical body 1112 is 11.5 mm and the thickness of the belt-shaped body is 50 μm, the inner diameter of the paper pipe 1110 is 11.5−50 / 1000 × 2 = 11.4 mm at the overlapping portion of the belt-shaped body. It becomes. However, since the inner diameter of the paper pipe 1110 in this case is larger than the diameter 11 mm of the game ball P, the game ball P can flow.

  As long as the strip of the polymer resin layer 1111 has at least a water vapor permeability lower than that of the cylinder 1112, compared to the case where the polymer resin layer 1111 is not present, moisture stripped out of the cylinder 1112. The amount can be reduced.

  Examples of the polymer resin band include, for example, Zeklon (registered trademark) (polyacrylonitrile (hereinafter referred to as “PAN”)-based resin Barex (registered trademark) formed into a sheet) 30 μm film, Hytron (registered trademark) ) BX (PAN-based resin) 30 μm film, Hytron (registered trademark) PG (polyethylene terephthalate (hereinafter referred to as “PET”)-based resin) 30 μm film, or the like can be used.

However, the present invention is not limited to this, and the polymer resin band may be any other polymer resin as long as the water vapor permeability at 40 ± 0.5 ° C. and 90 ± 2% RH is 1000 g / m ² · 24 h or less. It may be a film. In general, the polymer resin film has a lower water vapor permeability than paper such as cardboard of the cylindrical body 1112. The water vapor permeability of the polymer resin in the inner layer of the lifting pipe is less than a predetermined value and is lower than that of the paper pipe 1110. If such a polymer resin film is used, when the game ball is passed through the inside of the lifting pipe by the lifting device, it is easy to leave the moisture of the game ball P (for example, lactate). it can. As a result, the dirt can be removed without making it difficult to remove the dirt of the game ball.

  For example, polymer resin strips include PVDC (polyvinylidene chloride, VDC-MA copolymer (vinylidene chloride-methacrylic acid copolymer)), EVOH (EVA (ethylene-vinyl acetate copolymer) saponified product), OV. (PVDC-coated stretched PVA), MXD6 (metaxylidene adipamide), PAN, PVDC-coated ONy (biaxially stretched polyamide), PVDC-coated cellophane, PVDC-coated OPP (biaxially stretched polypropylene), ONy, CNy (unstretched polyamide) ), Cellophane, PVDC (VDC-VC copolymer (vinylidene chloride-vinyl chloride copolymer)), PET, PVC (polyvinyl chloride), OPP, HDPE (high density polyethylene), CPP (unstretched polypropylene), PC (polycarbonate) ), PS (polystyrene), LDPE (low density Plastic film for food packaging, such as ethylene) ( "Science and Industry", 80 (12), it may be a p602~608,2006).

These plastic films for food packaging have a thickness of 25 μm and a water vapor permeability of 1000 g / m ² · 24 h or less. In a polymer resin film, it is said that the film thickness and water vapor permeability have an inversely proportional relationship. That is, if the film thickness is increased by X times, the water vapor permeability becomes 1 / X times.

  As long as the above-described criteria are satisfied, the polymer resin band is a single film (EVOH-based resin film, PVDC-based film, nylon-based film, etc.) or a coated film (PVDC-coated film, acrylic resin-based coating film, etc.). May be. Moreover, it is a vapor deposition film (aluminum vapor deposition film, alumina vapor deposition film, silica vapor deposition film, binary vapor deposition film), co-extrusion film (ONY-based co-extrusion film, EVOH co-extrusion OPP film, PVA-coated OPP film), and laminated film. May be.

  The water vapor permeability of the polymer resin strip is preferably quaternary or lower among the water vapor permeability classifications defined in “General Rules for Plastic Films for Food Packaging” of JIS Z1707, more preferably Grade 3 or less, Grade 2 or less, or Grade 1.

The classification of water vapor permeability of JIS Z1707 is as follows: 1st grade is 1 or less, 2nd grade is more than 1 and 5 or less, 3rd grade is more than 5 and 20 or less, 4th grade is more than 20 and less than or equal to 100, The fifth grade is over 100, and the unit is g / m ² · 24 h. Each grade of plastic film for food packaging can be used properly depending on the application and cost, so it can be said that the classification has a critical significance.

  The water vapor transmission rate is defined in JIS K7129 “Plastic-Film and Sheet—How to Obtain Water Vapor Transmission Rate (Equipment Measurement Method)” or JIS Z0208 “Moisture-permeable test method for moisture-proof packaging materials (cup method)”. Can be determined by testing.

  In addition, as long as the belt-like body of the polymer resin layer 1111 has a lower oxygen gas permeability than that of the cylinder 1112, it flows from the outside of the cylinder 1112 compared to the case where the polymer resin layer 1111 is not provided. Can reduce the amount of oxygen.

As a polymer resin strip, other polymer resin films may be used as long as the oxygen gas permeability at 23 ± 0.5 ° C. and 50 ± 2% RH is 5000 fmol / m ² · s · Pa or less. Good. In general, the polymer resin film has lower oxygen gas permeability than paper such as cardboard of the cylindrical body 1112. The oxygen gas permeability of the polymer resin in the inner layer of the lifting pipe is below a predetermined value and is lower than that of the paper pipe 1110. If such a polymer resin film is used, inflow of oxygen to the inside of the lifting pipe can be suppressed when a game ball is caused to flow through the lifting pipe by the lifting device. As a result, it is possible to prevent the occurrence of contamination due to oxidation of each part of the lifting device. Moreover, generation | occurrence | production of the oxidation odor by oxidation of dirt can be suppressed.

For example, among the polymer resins having low water vapor permeability described above, PVDC, EVOH, OV, MXD6, PAN, PVDC coat ONy, PVDC coat cellophane, PVDC coat OPP, ONy, CNy, cellophane, PVDC, PET, PVC For example, it is 25 μm and the oxygen gas permeability is 5000 fmol / m ² · s · Pa or less. In a polymer resin film, it is said that the film thickness and oxygen gas permeability have an inversely proportional relationship. That is, if the film thickness is increased by X times, the oxygen gas permeability becomes 1 / X times.

  The oxygen gas permeability of the polymer resin strip is preferably 4 or less, more preferably among the oxygen gas permeability class categories defined in “General Rules for Plastic Films for Food Packaging” of JIS Z1707. Is grade 3 or less, grade 2 or less, or grade 1.

In addition, the classification of oxygen gas permeability of JIS Z1707 is 5 for the first grade, 2 for the second grade, and over 25 for the third grade, over 25 for the third grade, and 100 for the fourth grade, over 100 for the fourth grade. The fifth grade is over 500, and the unit is fmol / m ² · s · Pa. Each grade of plastic film for food packaging can be used properly depending on the application and cost, so it can be said that the classification has a critical significance.

  Oxygen gas permeability is measured according to JIS K7126-1 “Plastics—Film and Sheet—Gas Permeability Test Method—Part 1: Differential Pressure Method” or JIS K7126-2 “Plastic—Film and Sheet—Gas Permeability Test Method— It can be obtained by the test prescribed in “Part 2: Isobaric method”.

  Further, the inner surface of the polymer resin layer 1111 is higher than the case where the polymer resin layer 1111 is not provided on the inner surface of the cylinder 1112 if at least the dynamic friction coefficient and the static friction coefficient are lower than the inner surface of the cylinder 1112. Friction between the inner surface of the feed pipe and the game ball P can be reduced. In general, the polymer resin film has a lower coefficient of dynamic friction and a lower coefficient of static friction than paper such as cardboard of the cylinder 1112. As a result, it is possible to smoothen the flow of the game ball of the lifting pipe.

  The dynamic friction coefficient and the static friction coefficient can be determined by a test defined in “Plastic-film and sheet-friction coefficient test method” of JIS K7125.

  The cylinder 1112 and the polymer resin layer 1111 are fixed by being attached with an adhesive. As the adhesive, it is possible to use an adhesive that can be applied to both the plastic of the polymer resin layer 1111 and the paper of the cylindrical body 1112 such as an epoxy adhesive, an acrylic adhesive, and a double-sided adhesive tape.

  Moreover, if the gas barrier adhesive for films is used, the gas barrier property of water vapor and oxygen gas of the polymer resin layer 1111 can be improved.

  Although the embodiments of the present invention have been described with reference to the drawings, the specific configuration is not limited to these embodiments, and modifications and additions within the scope of the present invention are included in the present invention. It is.
