Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an in-cage illumination lamp burnout notification device for an elevator having a one-lamp type illumination device.

[0002]

[Prior art]

 An emergency light that was originally designed to light up in an emergency such as a power outage was used by temporarily lighting it as a method of responding when the lighting of a single-lamp lighting system has run out in the conventional car. A method of doing so is proposed in Japanese Utility Model Application Laid-Open No. 1-166999.

[0003]

[Problems to be solved by the device]

 However, with the conventional method of lighting an emergency light provided for an emergency, the elevator can be used as usual even if there is dissatisfaction in terms of brightness, so there is a risk that the elevator will be used without replacing the lighting. In addition to the above, there is concern that a circuit may be added for temporary use, such as during an originally required power outage, or a malfunction may occur due to the use of emergency lights during normal times.

It is an object of the present invention to provide an in-car illumination light out notification device capable of promptly notifying a manager or the like that an illumination light has run out.

[0005]

[Means for Solving the Problems]

 The object of the present invention is to detect the lighting state of the lighting device around the lighting device in an elevator car in-car lighting notification device that has a single-light type lighting device in the car and a door. And a control circuit for moving the car to the reference floor when the light sensor detects non-lighting of the lighting device and for continuing the door open after the movement is completed. .

[0006]

[Advantageous Effects] According to the present invention, the light sensor detects that the lighting device in the car lighting device is out of light, and at the time of detection, the car is moved to the reference floor, and then the door is in the open state, which allows the car to be opened from a distance. The manager can know that the lights in the car are off, and can immediately perform replacement work.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a control circuit diagram showing an embodiment of the present invention, and FIG. 2 is an explanatory diagram showing a state in which an optical sensor is attached to an elevator illuminating device. In the figure, reference numeral 1 denotes an illuminating lamp, and a ring type fluorescent lamp is used in the present embodiment, but it goes without saying that non-lighting can be similarly detected even in a straight tube or a light bulb.

An optical sensor 2 is mounted near the illuminating lamp 1, and is provided with a normally-closed contact 2b that operates when detecting that the illuminating lamp 1 is cut off and the illumination suddenly decreases. Reference numeral 3 is a relay for detecting the operating state of the optical sensor, which is provided with normally open contacts 3b ₁ and 3b ₂ . Reference numeral 4 is a relay that gives an operation command for moving the elevator to the standard floor by energization, and has a normally open contact 4b. Reference numeral 5 is a relay for limiting the closing of the door. When the relay 5 operates, the door continues to open. Reference numeral 6 is a relay that detects that the elevator has moved to the standard floor and the door has been opened, and has a normally closed contact 6b. Reference numeral 10 is a normally closed contact that opens when the door is fully opened. P and N are power supplies.

Next, the operation of this embodiment will be described. If the illuminating lamp 1 is cut off now, the optical sensor 2 detects that the illuminance of the illuminating lamp 1 suddenly becomes low (zero), and the normally closed contact 2b is closed. As a result, the photosensor operation detection relay 3 is excited and the normally open contacts 3b ₁ and 3b ₂ are closed. By closing the normally open contact 3b _1, the reference floor operation command relay 4 is excited, and the destination floor for moving the car to the reference floor (in this embodiment, the entrance floor where the manager is located) is registered and , Normally open contact 4b is closed. When the car reaches the standard floor and the door is opened by this destination floor registration, the door is fully opened and the normally closed contact 10b is opened. As a result, the standard floor door opening completion relay 6 is demagnetized and the normally closed contact 6 is closed. When the door of the car is moved to the standard floor, the normally open contacts 3b ₂ and 4b and the normally closed contact 6b are all closed, the relay 5 that restricts the closing of the door is excited, and then the illumination lamp 1 is replaced. Then, the elevator is put into the non-service state until the illuminance of the lamp 1 is detected by the optical sensor.

Since the elevator stops with the door open on the floor where the manager is present, it can be known from a distance that the elevator is not in service, and the manager will immediately replace the lights.

Next, another embodiment of the present invention will be described. FIG. 3 shows a control circuit according to another embodiment of the present invention, in which the structure for detecting the burnout of the illuminating lamp is the same as the method described in the above embodiment, and has the structure shown in FIG. . Further, there are some portions having the same configuration, and the description of those portions will be omitted.

The normally open contact 3a of the relay 3 that detects the operating state of the optical sensor 2 and outputs a door opening command is 3a, and 7 is a relay for operating a closed button provided in a car (not shown), Reference numeral 8 is a relay for outputting a door closing command which is output when a predetermined time has elapsed after the door is opened. When the relays 7 and 8 are excited, the close button can be operated. When the time has passed, a door close command is issued to automatically close the door. Reference numeral 9 is a notification relay, and when excited, it causes a lamp that is provided in or near the open button in the car to blink when operating the open button. The normally closed contact of this relay 9 is 9b. 10b ₁ is a normally-closed contact that opens when the door is fully opened. Unlike the previous example, no matter which floor the door opens, the contact opens when the door is fully opened, and the door open completion relay 11 is opened. Degauss. The normally closed contact of the relay 11 is 11b.

Next, the operation of this embodiment will be described. When the illuminating lamp 1 in the car is cut off and the optical sensor 2 detects that the illuminating lamp is broken from the change in illuminance and closes the contact 2b, the relay 3 is excited and a door open command is issued and the normally open contact 3a is closed. . When the door is fully opened, the normally closed contact 10b is opened and the door fully open detection relay 11 is demagnetized. The normally closed contact 11b is closed due to the demagnetization of the relay 11, and the alarm relay 9 is excited through the already closed normally open contact 3a, and the lamp provided in the open button in the car blinks. Further, since the normally closed contact 9b is opened by the excitation of the relay 9, the closing button operation relay 7 and the door closing command output relay 8 are demagnetized, so that the door does not close even if the closing button is pressed, and the door does not close for a predetermined time after the door is fully opened. The door close command is not output even after the passage, and the door remains open. That is, it becomes a non-service state.

As described above, when the illumination light in the car is cut off, the elevator is brought into a non-service state, and therefore the service is not performed in a state where the inside of the car is in the dark. Also, the blinking of the open button in the car can inform the user that the elevator is out of service.

[0015]

[Effect of device]

 In the present invention, it is possible to know that the elevator is not servicing from a long distance by stopping the door at the reference floor when the optical sensor detects that the light is not lit.

Further, when the light sensor detects non-lighting, at the nearest floor, when the door is fully opened, the blinking of the open button can inform the user that the car is in the dark and the service is not performed.
