  DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of an operation confirmation jig for a position detection apparatus according to the present invention will be described below with reference to the drawings.

  FIG. 1 is an overall configuration diagram showing an outline of an elevator to which an operation checking jig of a position detection device according to the present invention is applied. FIG. 1 shows the overall configuration of an electronic safety-compatible elevator equipped with a safety system that is a software system of a safety system that has been conventionally constituted by mechanical elements such as limit switches.

  The car 1 and the counterweight 11 move up and down in the hoistway when the motor 2 drives the main rope 10. The motor 2 is driven by an inverter 5 connected to an AC power source 7 via a cutoff circuit 6. The shut-off circuit 6 operates for safety when the operation of the door switch 70 of the car 1 or the door switches 71 to 73 of the halls on the floor where the car 1 does not exist is detected while the car 1 is moving. Then, power supply to the motor 2 is cut off. As a result, the driving force of the motor 2 is lost, and the hoisting machine brake 3 is operated by cutting off the power supply to the hoisting machine brake 3. The hoisting machine brake 3 is a constantly operating type in which the brake is released by energization.

  The governor rope 12 is provided so as to circulate between the pulley 13a provided at the top of the hoistway and the governor 13 provided on the floor of the hoistway, one of which is provided in the car 1. It is fixed to an emergency stop device 15 that slides on the rail 16. Thus, when the car 1 moves, the governor rope 12 is pulled by the emergency stop device 15, and as a result, the governor 13 is driven to rotate. The governor 13 includes a gripping device 14 and a rotary encoder 21. When the speed of the governor 13 exceeds a predetermined speed, the gripping device 14 operates to grip and stop the governor rope 12. At this time, when the car 1 is moving, the safety device 15 detects the stop of the governor rope 12 and pinches the rail 16 to suddenly stop the car 1.

  The rotary encoder 21 rotates with the governor 13 to generate a pulse signal. The controller 30 in the elevator controller 50 calculates the speed of the car 1 by calculating the position of the car 1 and the time average of the amount of change by accumulating the amount of generated pulse signals. Control up and down.

  A position detection sensor 80 is mounted on the car 1. When the car 1 arrives at the destination floor, the position detection sensor 80 operates by facing the detected bodies 81, 82, 83 installed on the destination floor on the hoistway side. A signal indicating the stop position (door openable zone) is sent to the safety controller 40.

  A shock absorber 17 is installed at the lower end of the hoistway, and even when the car 1 cannot be completely stopped by the braking force of the hoisting machine brake 3 or the emergency stop device 15, it receives the car 1 and absorbs the impact.

  Final limit switches 22 and 23 are provided near the lower end and the upper end of the hoistway. The final limit switches 22 and 23 are normally in an off state, but are turned on when the car 1 enters below and above the final limit switches 22 and 23, respectively. The controller 40 detects this signal and detects that the position of the car 1 exceeds the normal operation range.

  The controller 30 described above controls the inverter 5, and refers to the input information of the destination floor button in the in-car operation panel 60 with the car position indicator and the landing buttons 61, 62, 63 and the like. Let it run. On the other hand, the safety controller 40 refers to the outputs of the rotary encoder 21 and the final limit switches 22 and 23 to detect an event such as overspeed or overposition of the car 1 according to the position of the car 1, The car 1 is braked by the emergency stop device 15 through the machine brake 3, the breaking circuit 6, and the gripping device 14.

  FIG. 2 is a perspective view illustrating an example of a plurality of position detection devices provided in an elevator that is an operation check target according to the first embodiment.

  Each of the single position detection devices 80a, 80b, 80c constituting the position detection sensor 80 described above is provided with a light emitting portion and a light receiving portion facing each other in the recess. In the hoistway, a plurality of detected bodies 81, 82, 83 are arranged at the upper end or the lower end, or at each door zone. When the car 1 is not located at any position other than the upper end or lower end of the hoistway or each door zone, the light from the light emitting parts of the position detecting devices 80a, 80b, 80c has reached the light receiving part. The detection devices 80a, 80b, and 80c do not operate. On the other hand, when the car 1 is located at the upper end or lower end of the hoistway or the door zone, the detected object is inserted into the recesses of the position detection devices 80a, 80b, 80c, so that the light from the light emitting unit is emitted. As a result, the position detection devices 80a, 80b, and 80c operate. In particular, when the position detection devices 80a, 80b, and 80c are simultaneously operating while being shielded, the safety controller 40 determines that the car 1 has reached the upper end or the lower end of the hoistway, and the car 1 Is controlled to stop the car 1 so that it does not move beyond the upper end or lower end of the hoistway.
