Next, the control system of the gaming machine inspection facility S will be described.
As shown in FIG. 4, the inspection equipment control device 36 includes an operation panel 70, first and second jig detection sensors 71 and 72, an inspection number count SW 73 (“SW” means a switch), 1 A pair of conveyor driving units 30 a for driving the pair of first belt conveyors 30, a conveyor driving unit 31 a for driving the second belt conveyor 31, an inspection management indicator 74, and an inspection machine 50 for a plurality of inspection stages 34. Is connected.

  The inspection facility control device 36 controls the first and second belt conveyors 30 and 31 based on signals from the operation panel 70, the first and second jig detection sensors 71 and 72, and the inspection number count SW 73. The inspection management display 74 is controlled based on signals from the above. Although the inspection facility control device 36 can communicate various information with the plurality of inspection machines 50, the plurality of inspection devices 50 may be provided independently without being connected to the inspection facility control device 36.

  The operation panel 70 can command the start and stop of the operation of the first and second belt conveyors 30 and 31, can set the transport speed of the first and second belt conveyors 30 and 31, and can manage the inspection. A plan (planned number of inspections) to be displayed on the display 74 can be input.

  The first jig detecting sensor 71 is a first jig detecting means for detecting the inspection pallet jig 32 placed on the jig placing table 33a of the loading stage 33. For example, the first jig detecting sensor 71 is placed on the jig placing table 33a. It consists of a reflected light sensing type optical sensor having a light emitting part and a light receiving part installed rearward. The second jig detecting sensor 72 is a second jig detecting means for detecting the inspection pallet jig 32 on the second belt conveyor 31 at a fixed position downstream in the transport direction. The optical sensor is the same as that described above and is installed near the boundary with the two-belt conveyor 31 toward the second belt conveyor 31.

  The inspection facility control device 36 stops the operation of the second belt conveyor 31 on condition that both the first and second jig detection sensors 71 and 72 detect the inspection pallet jig 32. Therefore, it is possible to prevent the inspection pallet jig 32 on the second belt conveyor 31 from colliding with the inspection pallet jig 32 on the jig mounting table 33a. In addition, the conveyor control including the said operation stop control which the inspection equipment control apparatus 36 performs is as showing in FIG.

If the determination in S4 is No, it is determined whether or not an emergency stop command is input ( S5). If the determination at S4 is Yes or the determination at S5 is Yes, the first and second belt conveyors 30, 31 are deactivated (S6) and the process returns.

  On the other hand, if both the determinations in S4 and S5 are No, it is determined whether or not the first jig detection sensor 71 is on (S7). If the determination in S7 is Yes, whether or not the second jig detection sensor 72 is on. Is determined (S8). When both the determinations at S7 and S8 are Yes, the operation of the second belt conveyor 31 is stopped (S9), and the process returns. On the other hand, if the determination in S7 is No or the determination in S8 is No, it is determined whether or not the second belt conveyor 31 is stopped (S10). If the determination in S10 is No, the process returns and the determination in S10 is Yes. In this case, since the first and second belt conveyors 30 and 31 are in the operation mode, the operation of the second belt conveyor 31 is started (S11) and the process returns.

  The inspection count SW 73 is installed on the collection stage frame Sb, and the inspection management indicator 74 is installed, for example, on the upper front side of the inspection equipment frame Sa. The inspection facility control device 36 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 74 to display them. The plan can be input on the operation panel 70 as described above, the result is added every time the inspection number count SW 73 is turned on, and the progress is calculated based on the plan and the result.

According to the gaming machine inspection facility S described above, the following operations and effects are achieved.
