  The game ball lifting device A is provided with a control unit (not shown) for controlling the opening / closing of the open / close door 64-6. This control unit is actually constituted by a control circuit. This control unit controls the start and stop of driving of the motor unit of the motor unit 64-1 while detecting the on / off state of the microswitch 64-9b and the microswitch 64-10b, thereby opening and closing the door 64-6. Do. That is, when the opening / closing door 64-6 is changed from the open state to the closed state, the control unit rotates the motor unit in the motor unit 64-1, and the motor unit rotates to rotate the rotor body 64-. 3a rotates counterclockwise as viewed from the X1 side, and when the micro switch 64-9b is in the on state and the micro switch 64-10b is in the off state, the rotation of the motor unit is stopped. . On the other hand, when the control unit changes the open / close door 64-6 from the closed state to the open state, the motor unit in the motor unit 64-1 rotates, and the motor unit rotates, whereby the rotor body 64-3a.

  Moreover, the said hanger plate 64-12 is a member which exhibits strip | belt-plate shape, as shown in FIG.7, FIG.8, FIG.9 etc., and is formed by sheet-metal-forming a steel plate in substantially flat shape. The width of the hanger plate 64-12 in the left-right direction, that is, the X1-X2 direction is formed longer than the interval between the side surface portion 64-8c and the side surface portion 64-8d of the shutter housing 64-8, and the protruding portion S13. The length between both ends of S23 is substantially the same. And the protrusion part S13, S23 and the hanger plate 64-12 are each provided with the screw hole in the corresponding position, and the screw | thread N can be screwed now. As described above, the hanger plate 64-12 is arranged at the upper end of the alignment rod 62, and the shutter housing 64-8 is suspended from the hanger plate 64-12, whereby the automatic shutter 64 is suspended from the alignment rod. State. It can be said that the hanger plate 64-12 functions as the “attaching means for attaching the hanger plate 64-12 in a state of being hung on the alignment rod”.

  In this embodiment, since the leg portions 64-8g and 64-8h and the hanger plate 64-12 are provided, the shutter housing 64-8 is installed on the installation surface and is hung from the alignment rod 62. It can also be installed reliably in a desired installation state.

  In the automatic shutter 64, the configuration excluding the hanger plate 64-12 is an automatic shutter main body.

  Next, the use state and effects of the game ball lifting device A according to the present embodiment will be described. First, the basic movement in the automatic shutter 64 of the game ball inflow portion 60 will be described.

  When the motor unit 64-1 is driven, the crank rotor 64-3 rotates and drives the open / close door 64-6 up and down via the connecting rod 64-4.

  When the door 64-6 comes to the top, the comb teeth 64-6b protrude into the game ball route 62-3, and the game ball can be dammed up. In this way, the position where the open / close door 64-6 is at the top is the protruding position, and in this case, it can be said that the open / close door 64-6 is in the closed state. Here, when the door 64-6 is in the closed state, the door 64-6 is in the state shown in FIG. When the open / close door 64-6 comes to the lowest position, the comb teeth 64-6b are drawn from the game ball route 62-3, and the game ball can pass through the game ball route 62-3. Thus, the position where the open / close door 64-6 is at the lowest position is the storage position, and in this case, it can be said that the open / close door 64-6 is in the open state. Here, when the door 64-6 is in the open state, the door 64-6 is in the state shown in FIG.

  When the open / close door 64-6 is changed from the open state to the closed state, the control unit rotates the motor unit in the motor unit 64-1 so that the rotor body 64-3a is moved in the direction indicated by the arrow in FIG. Rotate. When the micro switch 64-9b is in the on state and the micro switch 64-10b is in the off state (this corresponds to the above “second state”), the rotation of the motor unit is stopped. Let In this way, the open / close door 64-6 is in the protruding position. That is, when the open / close door 64-6 changes from the open state to the closed state, the open / close door 64-6 changes from the state shown in FIG. 11 to the state shown in FIG. 8 through the state shown in FIG.

  Actually, when the micro switch 64-10b is in the off state, the micro switch 64-9b is in the on state. What is necessary is just to stop rotation of a part. In addition, when the timing when the open / close door 64-6 is closed is delayed from the timing when the micro switch 64-10b is turned off, the motor unit is turned on after the micro switch 64-10b is turned off. The delay time until the rotation is stopped is set so that the opening / closing door 64-6 is closed when the rotation of the motor unit is stopped, and the micro switch 64-10b is turned off. The rotation of the motor unit may be stopped after the delay time.

  On the other hand, when the door 64-6 is changed from the closed state to the open state, the control unit rotates the motor unit in the motor unit 64-1 so that the rotor body 64-3a is moved in the direction indicated by the arrow in FIG. Rotate. When the micro switch 64-9b is in an off state and the micro switch 64-10b is in an on state (this corresponds to the “first state”), the rotation of the motor unit is stopped. Let In this way, the open / close door 64-6 is in the storage position. That is, when the open / close door 64-6 changes from the closed state to the open state, the open / close door 64-6 changes from the state shown in FIG. 8 to the state shown in FIG. 11 through the state shown in FIG.

  Actually, when the micro switch 64-9b is in the off state, the micro switch 64-10b is in the on state. What is necessary is just to stop rotation of a part. In addition, when the timing when the open / close door 64-6 is opened is delayed from the timing when the micro switch 64-9b is turned off, the micro switch 64-9b is turned off after the motor switch is turned off. The delay time until the rotation is stopped is set so that the opening / closing door 64-6 is opened when the rotation of the motor unit is stopped, and the micro switch 64-9b is turned off. The rotation of the motor unit may be stopped after the delay time.

  When the open / close door 64-6 is changed from the closed state to the open state, the open / close door is inclined as shown in FIG. That is, in FIG. 10, the left side in the figure is the upstream side in the direction of the game ball flow, but the open / close door 64-6 is inclined to the downstream side. As a result, the game ball that has been dammed by the open / close door 64-6 can easily flow to the downstream side, and the game ball can flow smoothly to the downstream side.

  The motor unit 64-1 rotates in one direction both when the open / close door 64-6 is changed from the closed state to the open state and from the open state to the closed state. is not.

  Here, the open / close door 64-6 moves up and down as described above. At this time, the shaft portion 64-7a and the shaft portion 64-7b are provided on both sides in the side view of the open / close door 64-6. When the open / close door 64-6 moves up and down in contact with the shaft portion 64-7a and the shaft portion 64-7b, the shaft portion 64-7a and the shaft portion 64-7b rotate. 6 can move up and down smoothly. That is, when the door 64-6 moves downward, the shaft 64-7a rotates clockwise in FIG. 8 and the shaft 64-7b rotates counterclockwise as the door 64-6 moves. The shaft portions 64-7a and 64-7b supporting the standing state of the open / close door 64-6 do not become an obstacle. Similarly, when the opening / closing door 64-6 moves upward, the shaft portion 64-7a rotates to the left in FIG. 8 and the shaft portion 64-7b rotates to the right as the opening / closing door 64-6 moves. Therefore, the shaft portions 64-7a and 64-7b supporting the standing state of the open / close door 64-6 do not become an obstacle.

  Furthermore, since the shaft portions 64-7a and 64-7b are made of nylon, the surfaces thereof are formed smoothly, and the vertical movement of the open / close door 64-6 can also be smoothly performed.

  Note that the motor unit 64-1, the motor bracket 64-2, the crank rotor 64-3, the connecting rod 64-4, and the like are "drive mechanism for opening and closing the door" or "the door is opened and closed. To act as a drive mechanism for opening and closing the door.

  Next, lifting by the game ball lifting device A will be briefly described. When lifting, the open / close door 64-6 of the automatic shutter 64 in the game ball inflow portion 60 is closed, and the game ball is blocked by the open / close door 64-6. As a route to the game ball inflow portion 60, for example, a game ball collected through a collection route on a pachinko island is guided to reach the game ball inflow portion 60. In the operation of the game ball lifting device A, when the power of the game ball lifting device A is turned on, the open / close door 64-6 needs to be closed. If the closed door 64-6 is in an open state when the power is turned on, that is, if the micro switch 64-9b is in an off state, an error is detected and this is notified.

  First, automatic operation in the automatic mode will be described. When the automatic start switch 1004 is pressed while the mode changeover switch 1002 is in the automatic mode, the control unit detects this and drives the motor 52 in the rotation drive unit 51. At the same time, the open / close door 64-6 of the automatic shutter 64 is opened.

  Then, the rotating pulley 53 rotates with the rotation of the motor 52, and the feeding belt YB circulates with the rotation of the rotating pulley 53. That is, the lifting belt YB is conveyed in a circular manner. In this case, the lifting belt YB rises at a position where the lifting cylinder main body 20 and the opening / closing cover 30 face each other, and the lifting belt YB moves down outside the lifting cylinder main body 20. The fabric belt NB is in a stopped state.

  Further, by opening the open / close door 64-6 in the automatic shutter 64, the game balls can flow downstream, and can reach the curved introduction rod 4 from the alignment rod 62. Note that the opening / closing door of the automatic shutter 64 is opened after a predetermined time (for example, about 10 seconds) has elapsed since the driving of the motor 52 in the rotation driving unit 51 is started. That is, the control unit controls the timing at which the open / close door 64-6 of the automatic shutter 64 is opened. Therefore, since the released game balls are immediately lifted and discharged, the game balls are not immediately lifted but accumulated inside the alignment basket 62 and prevented from overflowing from the upper part or the like. It becomes possible.

  When the game balls reach from the alignment rod 62 to the curve introduction rod 4, the path between the fabric belt NB and the curve introduction rod 4 is moved by the friction with the conveyed conveyance belt YB. The path between the tube body 20 and the opening / closing cover 30 is raised. In the path between the lifting cylinder main body 20 and the opening / closing cover 30, the game ball rises while being sandwiched between the lifting belt YB and the cloth belt NB. It rises while being polished by friction with the belt NB. The game balls that have risen are discharged from the game ball discharge section 70 and guided to a ball tank or the like in the pachinko hall.

  In the game ball lifting process, as the game ball rises, the cloth belt NB is also pulled upward in the game ball transport path. In the cloth belt collecting mechanism section 40, the cloth belt transport section 310 The cloth belt NB is fixed in a state of being sandwiched between the driving roller and the pair of pressure feeding rollers, and the cloth belt NB is wound in the cloth belt winding portion 300, so that the cloth belt NB is moved upward. It will not move.

  When stopping the operation during the automatic operation, the automatic stop switch 1006 is pressed. Then, the control unit detects that the switch has been pressed, closes the open / close door 64-6 of the automatic shutter 64, and stops the driving of the motor 52 in the rotation drive unit 51. Thereby, the lifting of the game ball is stopped. The timing at which the open / close door 64-6 of the automatic shutter 64 is closed is a predetermined time (for example, 20 seconds before) before the driving of the motor 52 in the rotation drive unit 51 is stopped. That is, the driving of the motor 52 is stopped a predetermined time after the open / close door 64-6 of the automatic shutter 64 is closed. By doing in this way, the game ball in the lifting columnar part 10 can be reliably discharged, and the gaming ball can be prevented from remaining in the lifting columnar part 10. Therefore, it is possible to prevent inconveniences such as scattering of the remaining game balls when the opening / closing cover 30 is opened when performing maintenance work of the game ball lifting apparatus A or the like.

  The case where the mode switch 1002 is in the manual mode will be briefly described. When the reduction machine drive / stop switch 1008 is switched to the drive side, the control unit detects this and drives the motor 52 in the rotation drive unit 51. Therefore, the game ball is lifted. On the other hand, when the reduction machine drive / stop switch 1008 is switched to the stop side, the control unit detects this and stops the driving of the motor 52 in the rotation drive unit 51. Thereby, the lifting of the game ball is stopped.

  When the shutter drive / stop switch 1010 is switched to the open side, the control unit detects this and opens the open / close door 64-6 of the automatic shutter 64. Thereby, the game ball can flow downstream. On the other hand, when the shutter drive / stop switch 1010 is switched to the closed side, the control unit detects this and closes the open / close door 64-6 of the automatic shutter 64. Thereby, the game ball is blocked by the open / close door 64-6.

  Further, when an operation of tilting the winding drive / stop switch 1012 to the driving side is performed, the control unit detects this and drives the motor unit in the fabric belt collecting mechanism unit 40 to collect the fabric belt NB.

  As described above, according to the game ball lifting device A of the present embodiment, the game ball lifting device A has the automatic shutter 64 that dams the flow of the game balls flowing into the alignment rod 62 at a predetermined position. The open / close door 64-6 is supported in an upright state between the cylindrical shaft portion 64-7a and the cylindrical shaft portion 64-7b, and the shaft portions 64-7a and 64-7b are rotatable. Since it is provided and made of nylon, the door 64-6 can be opened and closed very smoothly.

  Further, since the connecting rod 64-4 can move slightly in the left-right direction (that is, the X1-X2 direction), the connecting rod 64-4 is provided on the bottom surface portion 62-1a of the main body frame 62-1 of the alignment rod 62. Even if the slit formation position slightly shifts in the X1-X2 direction, the shift can be absorbed, and the opening / closing of the open / close door 64-6 is not hindered.

  The open / close door 64-6 of the automatic shutter 64 has a substantially comb shape. Therefore, for example, when the opening / closing door has a simple flat plate shape, the opening / closing door 64-6 also enters the body frame 62-1 and the partition wall 62-2 of the alignment rod 62. Only the slit 62-4 on the bottom side is sufficient. Therefore, the part into which the open / close door 64-6 enters can be reduced, and the space part to be formed can also be reduced. Therefore, the structure can be simplified. Further, since the opening / closing door 64-6 has a comb shape, it can be made light in weight, so that it is not necessary to increase the strength of the alignment rod 62 more than necessary, and as a result, the cost of the alignment rod is reduced. It can be kept low.

  In addition, since the opening / closing door 64-6 protrudes upward from the bottom surface portion of the alignment rod 62 and blocks the flow of the game balls, as in the case of protruding from the top toward the bottom surface. In addition, game balls, dust, and the like are not sandwiched between the bottom surface of the alignment rod 62 and the open / close door 64-6. Therefore, there is no hindrance to the opening and closing of the opening and closing door 64-6, so that the flow of the game ball can be reliably blocked and the opening and closing of the opening and closing door 64-6 can be prevented. .

  In addition, since each comb tooth 64-6b of the open / close door 64-6 formed in an outer comb shape is formed corresponding to one game ball route 62-3 of the alignment rod 62, it is ensured. The flow of the game balls of each game ball route 62-3 can be blocked, and the comb teeth 64-6b are prevented from entering the partition wall portion 62-2 that partitions the boundary of each game ball route 62-3. be able to. Accordingly, since it is not necessary to form a space in the partition wall portion 62-2, the structure of the alignment rod 62 can be greatly simplified, and the strength of the alignment rod 62 can be sufficiently secured. In addition, interference between the open / close door 64-6 and the alignment rod 62 can be further reduced.

  The opening / closing door 64-6 and a driving mechanism for driving the opening / closing door 64-6 (motor unit 64-1, motor bracket 64-2, crank rotor 64-3, connecting rod 64-4, support member 64- 5, the shaft portions 64-7a and 64-7b, and the switch portions 64-9 and 64-10) are integrally formed as an automatic shutter 64 as a shutter unit, so that the opening and closing door 64-6 is driven. Adjustment and maintenance can be performed in the state of the automatic shutter 64. Accordingly, adjustment and maintenance of the driving of the open / close door 64-6 can be easily performed. In addition, since subassemblies can be performed in the state of the automatic shutter 64, field work in the pachinko hall can be reduced.

  Further, since the automatic shutter 64 has an outer shape that is substantially Okamochi and is suspended from the alignment rod 62, a special structure for attaching the automatic shutter 64 to the alignment rod 62 side is provided. It is not necessary to set, and can be easily applied to the alignment rod 62 having various model settings. In other words, the hanger plate 64-12 as the suspension member is provided at the upper end of the alignment rod 62, and the other components of the automatic shutter 64 are hung on the hanger plate 64-12. Since it is easy to attach to an automatic shutter 64 and a special structure for attaching the automatic shutter 64 is not required, it can be applied to various types of alignment rods.

  In the above description, it has been described that there are seven game ball routes 62-3 provided in the alignment basket 62, and the number of comb teeth 64-6b in the open / close door 64-6 is seven. It is not limited to.

  In the above description, the motor unit 64-1 rotates in one direction both when the open / close door 64-6 is changed from the closed state to the open state and when the door is changed from the open state to the closed state. However, the opening / closing door 64-6 may be rotated in different directions depending on whether the open / close door 64-6 is opened from the closed state or the open state.
