When the third air cylinder 85 is in the retracted state, the driven portion 56 of the inspection pallet jig 31 that has been transported leftward from the transport section 41 i to the transport section 41 j does not come into contact with the engagement member 87. It reaches the immediate front side.

  When the third air cylinder 85 is driven to extend in a state where the inspection pallet jig 31 does not stay in the conveyance section 41a on the downstream side in the conveyance direction of the conveyance section 41j, the inspection pallet jig in the conveyance section 41j is driven. 31 is conveyed to the conveyance section 41a.

Next, the control system of the gaming machine inspection facility S will be described.
As shown in FIG. 4, the inspection equipment control device 38 includes an operation panel 90, first, second, and third jig detection sensors 91, 92, 93, first and second cylinder operation SW 94, 95 ( “SW” means a switch), inspection number count SW 96, cylinder driving portions 75a, 80a, 85a for driving the first, second and third air cylinders 75, 80, 85, inspection management display 97, The inspection machine 70 of the inspection stage 33 is connected.

  The inspection facility control device 38 is based on signals from the first, second, and third jig detecting sensors 91, 92, 93, the first, second cylinder operation SW 94, 95, and the like. The air cylinders 75, 80, and 85 are controlled, and the inspection management display 97 is controlled based on signals from the operation panel 90, the inspection number count SW 96, and the like. The inspection facility control device 38 can communicate various information with the inspection machine 70, but the inspection device 70 and the inspection facility control device 38 may not be connected. On the operation panel 90, a plan (scheduled number of inspections) to be displayed on the inspection management display 97 can be input.

  The first jig detection sensor 91 is jig detection means for detecting whether or not the inspection pallet jig 31 stays in the transport section 41b or 41c, and the second jig detection sensor 92 is in the transport section 41a. It is a jig detection means for detecting whether or not the inspection pallet jig 31 is staying, and the third jig detection sensor 93 detects whether or not the inspection pallet jig 31 is staying in the transport section 41j. It is a jig detection means.

  The first, second, and third jig detection sensors 91, 92, and 93 have reflected light having a light emitting portion and a light receiving portion installed on the base table 30 toward the transport section 41b or 41c, 41a, and 41j, respectively. It consists of a sensing optical sensor. The first cylinder operation SW 94 is a SW that commands the operation of the first air cylinder 75, and the second cylinder operation SW 95 is a SW that commands the operations of the second and third air cylinders 80 and 85. The first and second cylinder operation SWs 94 and 95 are installed on the base table 30 so as to be operable on the closing stage 32.

  The inspection facility control device 38 prohibits the operation of the first jig pushing mechanism 35 on condition that the inspection pallet jig 31 is detected by the first jig detection sensor 91, and the second jig detection sensor 92 The operation of the third jig pushing mechanism 37 is prohibited on the condition that the inspection pallet jig 31 is detected, and the condition that the inspection pallet jig 31 is detected by the third jig detection sensor 93 is set. 2 The operation of the jig pushing mechanism 36 is prohibited. The cylinder control including the operation prohibition control executed by the inspection facility control device 38 is as shown in FIG.

  As shown in FIG. 13, in this cylinder control, it is first determined whether or not the first cylinder operation SW 94 is on (S1). If the determination of S1 is Yes, whether or not the first jig detection sensor 91 is on. It is determined (S2). If the determination in S2 is No, the first air cylinder 75 is driven back and forth (S3), and the process proceeds to S4. When the determination of S1 is No or the determination of S2 is Yes, the first air cylinder 75 is prohibited from operating, and the process proceeds to S4.

  Next, it is determined whether or not the second cylinder operation SW 95 is on (S4). If the determination in S4 is Yes, it is determined whether or not the second jig detection sensor 92 is on (S5). If the determination in S5 is No, the third air cylinder 85 is driven back and forth (S6). If the determination in S4 is No or the determination in S5 is Yes, the third air cylinder 85 is prohibited from operating and returns.

  After S6, it is determined whether or not the third jig detection sensor 93 is on (S7). If the determination in S7 is Yes, the execution of S5 will soon turn off the third jig detection sensor 93. The process waits in a state where the operation of the second air cylinder 80 is prohibited. After that, when the determination in S7 is No, the second air cylinder 80 is driven back and forth (S8) and returns. Thus, the second air cylinder 80 operates in conjunction with the operation of the third air cylinder 85.

  The inspection count SW 96 is installed on the base table 30 so as to be operable on the collection stage 34, and the inspection management display 97 is attached to the input equipment frame 30a, for example. The inspection facility control device 38 manages (stores / updates), for example, the plan (the planned number of inspections), the actual results (the number of completed inspections), and the progress, and causes the inspection management display 94 to display them. The plan can be input on the operation panel 90 as described above, the result is added every time the inspection number count SW 97 is turned on, and the progress is calculated based on the plan and the result. The inspection equipment control device 38 and the operation panel 90 are provided in the inspection equipment frame Sa.

According to the gaming machine inspection facility S described above, the following operations and effects are achieved.
As shown in FIG. 3, in this gaming machine inspection facility S, basically, one worker W is arranged on the input stage 32 and two workers (one person on the right side on the right side) An assistant is arranged, and one worker W is arranged on the collection stage 34.

  The plurality of inspection pallet jigs 31 provided in the jig circulation conveyance path 40 are circulated and conveyed along the jig circulation conveyance path 40. For this purpose, the operator W of the input stage 32 performs the first cylinder operation SW94. By the operation, the inspection jig 31 in the transport section 41a can be transported to the transport section 41b by the first jig pushing mechanism 35, and the third jig pushing mechanism can be operated by operating the second cylinder operation SW95. 37, the inspection pallet jig 31 in the transport section 41j is transported to the transport section 41a, and the inspection pallet jig 31 in the transport sections 41i to 41g is collected into the transport sections 41h to 41j by the second jig pushing mechanism 36. Can be transported.

  The operator W of the inspection stage 33 manually transports the inspection pallet jig 31 in the transport section 41d to the transport section 41e, transports the inspection pallet jig 31 in the transport section 41c to the transport section 41d, and Without using the first jig pushing mechanism 35, the inspection pallet jig 31 in the transport section 41b can be transported to the transport section 41c. The operator W of the collection stage 34 manually transports the inspection pallet jig 31 in the transport section 41f to the transport section 41g, and transports the inspection pallet jig 31 in the transport section 41e to the transport section 41f. The following operations are performed at each stage together with the circulating conveyance of the plurality of inspection pallet jigs 31.

  In the loading stage 32, the operator W first attaches the liquid crystal base 21 to the upper surface of the game board original plate 52 in the lying posture of the inspection pallet jig 31 in the transport section 41a, and the image display 22 is attached to the liquid crystal base 21. Are attached to the inspection pallet jig 31 together with the final assembly of the liquid crystal unit 20. Thereafter, the first and second cylinder operation SWs 94 and 95 are operated to execute the automatic conveyance of the inspection pallet jig 31. The above operations are repeated.

  In the inspection stage 33, the worker W connects the inspection connection terminal 73 to the connection terminal (not shown) of the game control device 24 of the liquid crystal unit 20 in the lying posture mounted on the inspection pallet jig 31 in the transport section 41c. Thereafter, the liquid crystal unit 20 is raised together with the game board original plate 52 (holding frame 53) and directed forward, and then the inspection operation device 71 is operated to check whether a predetermined function (operation) of the liquid crystal unit 20 is normal. After confirming, after the liquid crystal unit 20 is laid down together with the game board original plate 52, the inspection connection terminal 53 is separated. Thereafter, the manual conveyance of the inspection pallet jig 31 is performed. The above operations are repeated.

  At the collection stage 34, the operator W removes the collected liquid crystal unit 20 from the inspection pallet jig 31 in the transport section 41e or 41f and collects it. Further, the manual conveyance of the inspection pallet jig 31 is performed. The above operations are repeated.

  In this way, a plurality of inspection pallet jigs 31 are circulated and conveyed along the jig circulation conveyance path 40 of the base table 30, and the liquid crystal unit 20 is mounted on the inspection pallet jig 31 in the loading stage 32. Are sequentially performed every time the inspection pallet jig 31 arrives at the conveyance section 41a on the jig circulation conveyance path 40 corresponding to the input stage 32, and the inspection stage 33 is mounted on the inspection pallet jig 31. The operation of inspecting the liquid crystal unit 20 by switching the posture of the liquid crystal unit 20 between the standing posture and the lying posture is performed on the conveyance section 41 c on the jig circulation conveyance path 40 corresponding to the inspection stage 33. The operation is performed every time the tool 31 arrives, and in the recovery stage 34, the operation of removing and recovering the inspected liquid crystal unit 20 from the inspection pallet jig 31, Each time the inspection pallet jig 31 arrives at the transport section 41e or 41f on the jig circulation transport path 40 corresponding to the recovery stage 34, the three stages 32, 33, and 34 are used in order. Work can be done.

  In particular, in the inspection stage 33, the liquid crystal unit 20 can be tilted while being mounted on the inspection pallet jig 31, and can be inspected easily and reliably. At that time, the liquid crystal unit 20 is mounted on the inspection pallet jig 31. Since the liquid crystal unit 20 can be handled not too carefully, the work load on the inspection stage 33 can be reduced. Further, in the loading stage 32, the liquid crystal unit 20 can be easily mounted on the inspection pallet jig 31 in a lying posture, and on the collection stage 34, the liquid crystal unit 20 that has been inspected from the inspection pallet jig 31 is in a lying posture. Can be easily removed and recovered, and the work load on the input stage 32 and the recovery stage 34 can be reduced. Therefore, work efficiency can be improved.

  Since the jig circulation conveyance path 40 is formed in a rectangular annular conveyance path by arranging a plurality of conveyance sections 41 in which each inspection pallet jig 31 can stay, the base table 30 that forms the jig circulation conveyance path 40 is provided. It can be configured in a compact manner, that is, the installation space for the gaming machine inspection facility S can be reduced, and the work efficiency can be improved.

  The plurality of free ball casters 51 of each inspection pallet jig 31 are positioned at the four tops of the rectangular jig base 50 in plan view, and the jig circulation transfer path 40 is provided on the transfer path surface 42 for each inspection. Since the free ball caster 51 of the pallet jig 31 has the caster rolling surfaces 45 and 46 made of synthetic resin, the caster rolling surfaces 45 and 46 can be easily provided. The noise at the time of rolling on the conveyance path surface 42 (caster rolling surfaces 45 and 46) can be suppressed.

  A recess 47 into which the free ball caster 51 is fitted so that the inspection pallet jig 31 can be positioned in the four corner conveyance sections 41a, 41e, 41f, and 41j among the plurality of conveyance sections 41 of the jig circulation conveyance path 40. Are formed on the caster rolling surfaces 45 and 46, so that the inspection pallet jig 31 can be surely stayed in the transport sections 41a, 41e, 41f and 41j, and thereby the other transport sections 41b to 41d and 41g. The inspection pallet jig 31 can be surely stayed also in -41i, and thereby, the plurality of inspection pallet jigs 31 can be circulated and conveyed smoothly and work on the stages 32, 33, 34. Can be performed reliably.

  The first jig pushing mechanism 35 that pushes the inspection pallet jig 31 staying in the transport section 41a to the transport section 41b on the downstream side in the transport direction, and the inspection pallet jig 31 staying in the transport section 41g downstream in the transport direction. The second jig pushing mechanism 36 that pushes to the transport section 41h on the side, and the third jig pushing mechanism that pushes the inspection pallet jig 31 staying on the transport section 41j to the transport section 41a on the downstream side in the transport direction. Therefore, the gaming machine inspection facility S can be operated by the minimum required number of workers W (for example, about four people).

  In each inspection pallet jig 31, the game board original plate 52 to which the liquid crystal unit 20 can be attached and detached has the same structure as the original board of the game board 4, and therefore, a large number of game boards 4 that are mass-produced when the pachinko gaming machine 1 is manufactured. One of the original plates can be used as the game board original plate 52. Therefore, the liquid crystal unit 20 can be securely attached to the game board original plate 52, and the game board original plate 52 needs to be separately manufactured for inspection. Therefore, the manufacturing cost of the inspection pallet jig 31 can be reduced, and the equipment cost of the gaming machine inspection equipment S can be reduced.

  Moreover, since the liquid crystal unit 20 mounted on the game board original plate 52 can be moved up and down together with the game board original plate 52 and the holding frame 53 by the raising / lowering mechanism 55, the mounting operation of the liquid crystal unit 20 on the input stage 32, The inspection operation of the liquid crystal unit 20 at the inspection stage 33 and the removal and recovery operation of the liquid crystal unit 20 at the recovery stage 34 can be easily performed, and the work efficiency can be improved.

  Moreover, since the game board original plate 52 is detachably attached to the holding frame 53, game board original plates corresponding to various models can be easily applied. That is, the versatility of the inspection pallet jig 31 is increased, and the manufacturing cost of the inspection pallet jig 31 can be reduced, that is, the equipment cost of the gaming machine inspection equipment S can be reduced.

  In the second embodiment, the plurality of inspection pallet jigs 31 of the gaming machine inspection facility S of the first embodiment are changed to a plurality of inspection pallet jigs 31A. In the description of the structure of the inspection pallet jig 31A, the front and the upper in the state shown in FIGS. 14 to 16 are described as the front and the upper, and the same reference numerals are basically used for the same components as in the first embodiment. The description is omitted as appropriate.

  As shown in FIGS. 14 to 18, the plurality of inspection pallet jigs 31 </ b> A are obtained by changing the raising / lowering mechanism 55 of the inspection pallet jig 31 of the first embodiment. (Four) free ball casters 51, a game board master plate 52, a holding frame 53, a pair of lock mechanisms (not shown), a raising / lowering mechanism 55A, the liquid crystal unit 20 can be attached to and detached from the game board master plate 52, and liquid crystal Switchable between standing posture (posture shown in FIGS. 14 to 16) and lying down posture (posture shown in FIG. 18) same as the posture mounted on the game board 4 with the unit 20 mounted on the base board 52 of the game board It is configured.

  The raising / lowering mechanism 55 </ b> A places the liquid crystal unit 20 mounted on the game board original plate 52 in a standing posture and a lying posture, and the holding base 53 and the holding frame 53 can be raised and lowered together with the jig base 50. A pair of support legs 100, a pair of intermediate support members 101, a pair of shaft members 102, a pair of parallel link mechanisms 103, a pair of pin members 104, and a pair of bar members 105. The jig base 50 is provided with a driven portion 56. Each of the configurations 100 to 105 is provided in a pair symmetrically.

  The pair of support legs 100 is disposed on both left and right ends (width direction both ends) of the holding frame 53, and is erected on a pair of frame members 50 a of the jig base 50 from the center in the front-rear direction. The pair of intermediate support members 101 is made of a vertically oriented member that is slightly shorter than the support legs 100, and is disposed on the rear side of the pair of support legs 100. Are connected by a horizontal connecting member 101a.

  At the upper end portion of the pair of intermediate support members 101, a slightly rear side portion (intermediate portion in the length direction) of the pair of frame members 53a of the holding frame 53 is a pair of left and right axis. The member 102 is supported so as to be rotatable around a horizontal axis.

  Each of the pair of parallel link mechanisms 103 has two parallel upper and lower link members 103a disposed on the left and right sides of the pair of support legs 100 and the pair of intermediate support members 101, respectively. Both end portions of the link member 103 a of the parallel link mechanism 103 are rotatably connected to the lower portion of the support leg 100 and the lower portion of the intermediate support member 101.

  The raising / lowering mechanism 55A maintains the pair of intermediate support members 101 parallel to the pair of support legs 100 via the pair of parallel link mechanisms 103, and moves the holding frame while moving up and down while changing the position in the front-rear direction. 53 is rotated about the pair of shaft members 102 and tilted.

  The pair of pin members 104 protrude outward in the left-right direction of the holding frame 53 from the rear end portions of the pair of frame members 53a of the holding frame 53 (lower portions in the standing posture at both ends in the width direction). There is a slight gap between the pair of support legs 100 and the pair of intermediate support members 101 and the holding frame 53, so that the pair of pin members 104 does not interfere with the support legs 100 and the intermediate support member 101. It protrudes into the gap. For example, the pin member 104 may be configured with a screw member.

  The pair of bar members 105 are fixedly provided on the jig base 50, and the pair of pin members 104 are slidable while switching the posture of the holding frame 53 when the pair of intermediate support members 101 are moved up and down. The holding frame 53 is tilted by supporting the guide, and is inclined obliquely downward in the direction (front) in which the pair of pin members 104 move when the holding frame 53 stands up. Here, a pair of leg posts 106 are erected from a rear end portion of the pair of frame members 50 a of the jig base 50. The pair of bar members 105 are fixed to the left and right inner portions of the pair of support legs 100 and the left and right inner portions of the pair of leg posts 106 with screws or the like.

The operation and effect of the inspection pallet jig 31A will be described.
First, when the holding frame 53 (game board original plate 52) is in the lying posture shown in FIG. 16, the intermediate support member 101 is positioned below the upper end of the support leg 100, and the pin member 104 is positioned at the rear portion of the bar member 105. To position. Here, as shown in FIG. 16, in order to hold the holding frame 53 in the lying posture, the first lying posture holding member 107 that supports the front portion of the holding frame 53 from the lower side of the shaft member 102 is the supporting leg. A second lying posture holding member 108 that is attached to 100 and receives the rear end portion of the holding frame 53 from above is attached to the leg pillar member 106. The second lying posture holding member 108 can be omitted.

  Next, when the holding frame 53 in the lying posture is rotated so as to grasp and pull up the front end portion, the holding frame 53 is switched to the upright posture shown in FIG. 18 through the state of FIG. At that time, while the pin member 104 slides forward on the bar member 105, the holding frame 53 rotates upward about the pin member 104, and accordingly, the intermediate support member 101 is pulled upward and the support leg 100. Move to approach. Since the bar member 105 is inclined obliquely downward toward the front, the pin member 104 slides smoothly on the bar member 105 forward.

When the holding frame 53 is in the standing posture shown in FIG. 18, the intermediate support member 101 is substantially in contact with the support leg 100 and is positioned at the upper limit position above the upper end of the support leg 100, and the pin member 104 is on the front side of the bar member 105. Located in the part. Here, as shown in FIG. 18, in order to hold the holding frame 53 in an upright position, an upright posture holding member 109 that receives the lower portion of the holding frame 53 from the front side is attached to the support leg 100 . Since the bar member 105 is inclined obliquely downward toward the front, the pin member 104 engaged with the bar member 105 also prevents the holding frame 53 from rotating about the shaft member 102. Therefore, the holding frame 53 is reliably held in the standing posture.

  Eventually, the holding frame 53 pivots around the shaft member 102 and rises and falls. At this time, the shaft member 102 (intermediate support member 101) also moves up and down, and the height position of the shaft member 102 is Since the position in the standing posture is higher than the position in the lying posture, the position of the holding frame 53 in the standing posture is higher than the position of the holding frame 53 in the standing posture of the inspection pallet jig 31 of the first embodiment. . Note that when the holding frame 53 in the standing posture is rotated so as to hold the upper end of the holding frame 53 and pulled down, the holding frame 53 is switched to the lying posture shown in FIG. 16 through the state of FIG.

  According to the inspection pallet jig 31A, the height position of the holding frame 53 in the standing posture can be increased, which is advantageous in the following points. That is, when the liquid crystal unit 20 is mounted on the inspection pallet jig 32 at the loading stage 32, or when the liquid crystal unit 20 is removed from the inspection pallet jig 32 and recovered at the recovery stage 34, both the stages 32, 34 are used. In order to increase the work efficiency of the worker W (that is, to reduce labor), it is optimal to position the holding frame 53 (game board original plate 52) in the lying posture at the height position around the waist of the worker W. .

  On the other hand, when the liquid crystal unit 20 is inspected at the inspection stage 33, in order to increase the work efficiency of the worker W of the inspection stage 33, the lower portion of the holding frame 53 in the standing posture is placed at a height position around the waist of the worker W. It is best to position it. As in the first embodiment, when the holding frame 53 is simply tilted by turning the shaft member 61 about the center, in order to ensure the optimum position for all workers W, the loading stage 32 and the collection stage 34 are arranged. It is necessary to raise the standing position of the worker W. For this reason, a work table can be installed on the input stage 32 and the collection stage 34, but this is problematic in terms of the work stability of the worker W on the work table.

  In this inspection pallet jig 31A, since the height position of the holding frame 53 in the standing posture can be increased, the work table is unnecessary, that is, the standing positions of all workers W are the same level on the ground. As described above, the problem can be solved. That is, the work table is unnecessary, the work stability is improved, the work efficiency of all workers W can be increased, and the work table is not required, and the jig circulation transport path Since the height position of 40 can be lowered, the base 30 on which the jig circulation conveyance path 40 is formed can be made compact and stable, and the conveyance of the inspection pallet jig 31A can be stabilized. Further, it is advantageous in terms of equipment cost of the gaming machine inspection equipment S. The other effects are the same as those of the first embodiment.

  In addition, various modifications can be added without departing from the spirit of the present invention. For example, the present invention is applicable not only to the liquid crystal unit 20 but also to a gaming equipment inspection facility that inspects a presentation unit including a plurality of rotating drums or LED displays, and to a gaming equipment inspection facility that inspects gaming equipment other than such a presentation unit. Is possible.
