Description

  The present invention relates to an inspection device for a sphere detector that can appropriately inspect the sphere detector.

The game board of the pachinko machine is provided with a winning device, and a ball detector is attached to the winning device. As a sphere detector, there is known a sphere detector having a sphere detection hole that allows passage of a sphere from above to below, and detecting a sphere passing through the sphere detection hole by a change in impedance of a detection coil of a high-frequency oscillation circuit ( For example, see Patent Document 1 and Non-Patent Document 1). Conventionally, a ball detector (pachinko ball) used for a pachinko machine is dropped from above toward a ball detection hole of a ball detector positioned on an inspection table, and passed through the ball detection hole to perform a pass / fail inspection of the ball detector. A sphere detector inspection device was used. The inspection device for dropping the sphere is provided above the sphere detection hole of the sphere detector in which the electromagnet is positioned on the inspection table, and the magnet is demagnetized while the electromagnet attracts the sphere so that the sphere is moved downward from the electromagnet. It is a structure that falls toward the sphere detection hole of the sphere detector.

There is a drawback that it requires a lot of labor and time. Furthermore, since the diameter of the sphere detection hole that allows passage of the sphere provided in the sphere detector is formed to be close to the diameter of the sphere in order to improve detection performance, the sphere does not pass through the sphere detection hole. Can also occur. In this case, the work of attracting the sphere to the electromagnet and the switch operation for demagnetizing the electromagnet have to be performed again, and there is a disadvantage that much labor and time are required for the inspection of one sphere detector. .

The air cylinder device includes a cylinder (not shown), a passage switching valve, and a compressor as an air supply source. The cylinder includes a cylinder case, a piston that moves in the cylinder case, and a piston rod that projects outward from the cylinder head of the cylinder case. A head port and a bottom port are formed in the cylinder case. The passage switching valve includes an electromagnetic solenoid and a passage switching valve body driven by the electromagnetic solenoid.

  The electrical connection mechanism 5 will be described in detail with reference to FIGS. The electrical connection mechanism 5 includes a contact drive mechanism 36, a contact 35, a slider 65, and a guide body 66. The cylinder base 65B of the contact drive mechanism 36 is fixed to the lower surface of the inspection table 3 with a fixing tool such as a bolt (not shown). A notch 67 is formed on one side wall 18 a of the inspection portion 26 of the guide track 13. The connector insertion hole 56 of the ball detector 21 positioned in the inspection unit 26 is positioned above the bottom surface 68 of the notch 67. The guide body 66 of the contact 35 is provided so as to be connected to the notch 67. The guide body 66 linearly extends in the same direction as the direction orthogonal to the run direction of the runway 17 in the guide track 13. Similar to the guide track 13, the guide body 66 includes a runway 69 and both side walls 70; 70. The contact 35 is attached to a through hole 71 provided in a slider 65 that slides on the runway 69. The through hole 71 penetrates the runway 69 in the run direction. A spring mounting disc 73 is provided at one end 72 of the contact 35 held through the through hole 71 (the end connected to the electrical connection terminal 57 in the connector insertion hole 56 of the ball detector 21). The other end 74 of the contactor 35 is provided with a connection portion 75b of a connector 75a provided at the tip of the wiring 75. By connecting the front surface 76 of the slider 65 and the spring mounting disc 73 with a spring 77, the slider 65 and the contact 35 are connected with a spring 77. The slider 65 includes a connecting portion 79 that passes through a runway 69 and an escape hole 78 formed in the inspection table 3. The lower end portion of the connecting portion 79 and the tip end portion of the piston rod 80 of the contact drive mechanism 36 are connected to each other by a bolt / nut structure. By controlling the contact drive mechanism 36 so as to extend the piston rod 80, the contact 35 is connected to the electrical connection terminal 57 of the ball detector 21 sandwiched between the regulating body 33 and the extruded body 23 in the inspection unit 26, and the spring 77, the electrical connection state is maintained. By controlling the contact drive mechanism 36 so as to contract the piston rod 80, the contact 35 is detached from the electrical connection terminal 57, and the electrical connection state is released.

  With reference to FIG.3 (b), the raising / lowering mechanism 6 is demonstrated. The lifting mechanism 6 includes a subject 81, a support 82 that supports the subject 81, a guide column 83 of the support 82, a gear mechanism 84, and a step motor 85. The step motor 85 and the guide post 83 are fixed to the shelf 6a. The support body 82 includes an elevating body 86 that is held on the guide column 83 so as to be movable in the vertical direction, and a support bar 87 provided on the upper portion of the elevating body 86. A pinion 89 is provided on the motor shaft 88 of the step motor 85. A rack 90 is provided on the outer surface of the lifting body. A gear mechanism 84 is configured by the pinion 89 and the rack 90 that mesh with each other. As the subject 81, a so-called pachinko sphere as a sphere having a size that can be inserted into the sphere detection hole 51 of the sphere detector 21 is used. The subject 81 is fixed to the upper end of the support rod 87. The diameter of the support rod 87 is smaller than the diameter of the subject 81, and the subject 81 and the support rod 87 are bonded to each other by an adhesive so that the center line of the subject 81 and the center line of the support rod 87 coincide vertically. The

  The ball detector 21 located at the lowermost part of the supply unit 14 is pushed out from the one end 19 to the other end 20 of the guide track 13 by the pusher 23 of the pusher mechanism 15, and the tip of the plate 44 of the pusher 23. And the restricting body 33 of the restricting mechanism 16 so as to be positioned by the inspection unit 26. As shown in FIG. 3B, the height H1 other than the tip 44a of the plate body 44 of the extruded body 23 is the same as the height H of the ball detector 21, and the height of the tip 44a of the plate body 44 of the extruded body 23 is set. Since the height H2 is shorter than H1, the ball detector 21 can be smoothly pushed out by the extruded body 23. In the inspection unit 26, an inspection hole 91 penetrating the runway 17 of the guide track 13 and the inspection table 3 is formed below the center of the sphere detection hole 51 of the sphere detector 21 positioned in the inspection unit 26. The diameter of the circular inspection hole 91 is larger than the diameter of the spherical subject 81 and larger than the diameter of the circular sphere detection hole 51. The center of the subject 81 is located directly below the center of the inspection hole 91. That is, when the sphere detector 21 is positioned on the inspection unit 26, the sphere detection hole 51, the inspection hole 91, and the subject 81 are positioned coaxially in the vertical direction. Therefore, the control device 9 controls the motor shaft 88 of the step motor 85 to rotate in the forward and reverse directions, so that the subject 81 is detected and detected by the sphere detector 21 positioned and mounted on the examination unit 26 of the examination table 3. The hole 51 can be driven in and out linearly from below the inspection table 3 in the vertical direction.

  The control of the inspection apparatus will be described with reference to FIG. When a person operates the power switch operation unit 12a to turn on the power of the inspection device 1, the control device 9 is activated. The control device 9 inputs a commercial power supply 92, generates a power supply voltage to the sphere detector 21 by a power supply circuit (not shown), drives the electrical connection mechanism 5 to supply the power supply voltage to the sphere detector 21 and detects the sphere. The detection signal from the device 21 is input. The control device 9 includes a step motor 85, an electromagnetic solenoid 93 of the push drive mechanism 32, an electromagnetic solenoid 94 of the restriction drive mechanism 34, an electromagnetic solenoid 95 of the contact drive mechanism 36, an electromagnetic solenoid 96 of the discharge drive mechanism 38, the display 11, and the inspection result. The display lamps 12c; 12d are controlled. The control device 9 controls the electromagnetic solenoid 93 of the push drive mechanism 32 and the electromagnetic solenoid 94 of the restriction drive mechanism 34 by turning on the power to position the ball detector 21 at the inspection unit 26, and then the contact drive mechanism 36. The electromagnetic solenoid 95 is controlled, the contact 35 is connected to the electrical connection terminal 57 of the ball detector 21 positioned in the inspection unit 26, and the step motor 85 is controlled to control the ball detection hole of the ball detector 21. The inspection of the sphere detector 21 is performed by causing the subject 81 to pass and stop at 51. At this time, when the detection signal from the ball detector 21 is input, the control device 9 turns on the inspection result display lamp 12c to notify the inspection supervisor that the product is a non-defective product. When the detection signal from the ball detector 21 is not input, the control device 9 turns on the inspection result display lamp 12d to notify the inspection supervisor that the product is defective. Further, the control device 9 displays the position of the subject 81 with respect to the sphere detection hole 51 of the sphere detector 21 on the display screen 11 a of the display 11. When a person operates the emergency stop switch operation unit 12b to turn on the normal stop switch, the control device 9 stops driving the electromagnetic solenoid and the step motor that are being driven and returns to the initial state.

  The inspection process will be described with reference to FIGS. A person stacks a large number of ball detectors 21 on the supply unit 14 with the upper surface 21a of the ball detector 21 facing upward and the lower surface 21b facing the runway 17 (see FIG. 7A), and the power supply of the inspection apparatus 1 Is input, an inspection start signal is output to the control device 9. The control device 9 that has received the inspection start signal performs the following sequence control. First, as shown in FIG. 7B, the regulating drive mechanism 34 is controlled to lower the regulating body 33 in a direction approaching the runway 17 (see FIG. 7B). Next, the push-out drive mechanism 32 is controlled to advance the pusher 23 toward the inspection section 26 of the guide track 13, thereby moving the ball detector 21 toward the inspection section 26 (see FIG. 7C). Thus, when the ball detector 21 riding on the runway 17 located at the lowermost part of the supply unit 14 is pushed out by the pusher 23 to the inspection unit 26 of the guide track 13, it is placed on the ball detector 21. The sphere detector 21 is restricted from moving in the direction of the inspection unit 26 by the right side wall 59 and is kept on the upper surface of the extruded body 23. In a state where the ball detector 21 is moved to the inspection unit 26 and is sandwiched between the extruded body 23 and the regulating body 33, the contact driving mechanism 36 is controlled to connect the contact 35 to the electrical connection terminal 57 of the ball detector 21. To do. In this state, the elevating mechanism 6 is controlled to drive the subject 81 linearly in and out of the sphere detection hole 51 of the sphere detector 21 from the bottom of the inspection table 3 in the vertical direction. (See FIG. 8A). When the pass / fail inspection is completed, the contact drive mechanism 36 is controlled to remove the contact 35 from the electrical connection terminal 57 and raise the regulating body 33 (see FIG. 8B), and then the discharge drive mechanism 38 is controlled. Then, the extruded body 23 functioning as the discharge body 37 is advanced in the direction of the discharge section 28. As a result, the ball detector 21 whose inspection has been completed with the tip of the extruded body 23 exceeding the position of the regulating body 33 can be discharged to the discharge section 28 (see FIG. 8C). After the discharge operation is completed, the discharge drive mechanism 38 and the extrusion drive mechanism 32 are controlled to return the extruded body 23 to the initial position as shown in FIG. The detector 21 is inspected. When the ejected body 23 after the discharge operation is returned to the initial position, the ball detector 21 that has been on the upper surface of the extruded body 23 is restricted from moving in the direction of the one end 19 by the left side wall 58 and the runway 17. It falls down and is used for inspection. The ball detector 21 discharged to the discharge unit 28 is pushed by the subsequent ball detector 21 pushed out to the discharge unit 28 and moves to the non-defective tray 8.

  According to this embodiment, since the lifting mechanism 6 for the subject 81 is provided, the subject 81 can be accurately passed through the sphere detection hole 51 of the sphere detector 21 positioned in the examination unit 26 of the examination table 3. The sphere detector 21 can be properly inspected. Moreover, since the positioning mechanism 4 is provided, the ball detectors 21 can be accurately positioned on the inspection unit 26 of the inspection table 3 one by one. That is, it is not necessary to position the sphere detectors 21 one by one, and it is possible to reduce inspection labor and perform appropriate inspection. In addition, since the discharge mechanism 7 is provided, it is not necessary to remove each of the ball detectors 21 that have been inspected, and the labor for inspection can be reduced. That is, since the positioning mechanism 4, the electrical connection mechanism 5, and the discharge mechanism 7 are provided, the ball detectors 21 can be accurately positioned one by one on the inspection unit 26, and appropriate inspection can be performed. Since the sphere detector 21 that has been completed can be appropriately discharged up to the discharge portion 28, the inspection labor can be reduced. Furthermore, since the subject 81 can be moved up and down and the subject 81 can be stopped at a desired position, the catalog “TL-PP153 penetrating proximity switch” (catalog number TG-AYTL-010) of OMRON Corporation. The performance of the sphere detector 21 such as the detection range, the detection position, and the hysteresis distance described in the first page can be appropriately inspected.

  An elevating mechanism 6 is provided above the ball detector 21 positioned and mounted on the examination table 3, and the elevating mechanism 6 is linear in the vertical direction from above the ball detector 21 positioned and mounted on the examination table 3. It is good also as a structure driven in / out. Although the air cylinder device is used for the extrusion drive mechanism 32, the regulation drive mechanism 34, the contact drive mechanism 36, and the discharge drive mechanism 38, a cylinder device such as a hydraulic cylinder device may be used. The support 82 of the subject 81 and the guide column 83 of the support 82 may be coupled by a bolt / nut mechanism so that the support 82 of the subject 81 can be moved up and down.
