Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an elevator operating device operated by a dedicated driver.

Conventionally, in an elevator operated by a dedicated driver, the driver presses a destination button on an in-car operation panel to register a car call for a passenger's desired destination floor. When a passenger finishes boarding and alighting, the driver presses the operation button on the in-car operation panel, and the car door and landing door (hereinafter simply referred to as the door) are automatically closed and activated. On the other hand, the hall calls for each floor are registered using the hall buttons. The cars sequentially stop at the floors on which these car calls and hall calls are registered, and the doors are opened each time. When the car is driven to the highest and lowest floors for which the call has been registered, the driving direction is automatically reversed. Thereafter, the same operation as above is continued until heading in the direction after the reversal.
The above is normal driving by the driver, but other operations that the driver can perform include reversing a door that is closing to open it, reversing a door that is opening and closing it, and The direction of elevator operation may be reversed before servicing a floor, and the elevator may pass through a floor even if the floor is registered for a hall call. The driving device, which can be operated in a variety of ways, is originally operated only by a full-time driver, but when the driver leaves the car due to short errands or sudden circumstances requiring an emergency. You may leave. In such a case, the car will be under the control of an unspecified number of people. If an unspecified number of people operate the car, they may end up trapping passengers between doors due to inexperience, or they may drive straight to their destination floor by passing through the registered floor even though they can still get into the car. Namely, there were problems such as having many people wait in the elevator hall for a long time by using the elevator for private use, and reducing the transportation capacity of the elevator by leaving the car for a long time with the door open.

This invention was made in view of the above points, and when the driver leaves the car being driven by the driver, it prevents unspecified number of people from driving the car, thereby preventing passengers from getting on and off the car at the door. To provide an elevator operating device that prevents the car from being jammed or from being used for private purposes.

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

In the figure, 1 is equipped with a basket door 2 at the entrance.
An elevator car 5 that ascends and descends in a hoistway 4 surrounded by a wall 3 is provided near the entrance of the car 1, and includes an in-car operation panel provided with a destination button for registering the car call of the destination floor, etc. 6 is a driver who operates the car by operating the in-car operation panel 5; 7 is a driver absence detection device that is provided in the car 1 and consists of an ultrasonic transducer; 7a is a device that transmits beam-shaped ultrasonic waves in a pulsed manner; A transmitter 7b of the driver absence detection device 7 that transmits waves to
8 is a receiver of a driver absence detection device 7 that detects only the ultrasonic waves reflected from the driver 6 when the driver 6 is standing directly in front of the in-car operation panel 5 where the driver 6 is normally located; 8 is a hoistway 4 is the landing door installed at the entrance/exit, 9 is the elevator hall where passengers wait for the elevator, 10 is the landing button for calling the car,
11 and 12 are power supplies; 13 is a changeover switch provided on the in-car operation panel 5; one end is connected to the power supply 11; and 14 has one end connected to the power supply 12 and the other end connected to the other end of the changeover switch 13. 14a and 14b are normally open contacts, and 15 is a driver-operated relay with one end connected to the power supply 11 and the other end to the normally open contact 14.
A detection contact 16 is connected to the normally open contact 14a at one end and connected to the power supply 12 at the other end. In the operation prevention relay, 16a is its normally open contact, 16b is also a normally closed contact, and 17 is connected to the power supply 11 at one end and the normally open contact 16a at the other end, and is normally closed and can be operated with a key. 18 has one end connected to the power supply 11 and the other end connected to the normally open contact 14b, and the operation button 19 which is closed when pressed. 19 has one end connected to the normally open contact 14b and the other end connected to the normally open contact 14b. The call detection contact 20 is connected to the normally closed contact 16b and is closed when a car call or hall call is registered, and the call detection contact 20 has one end connected to the normally closed contact 16b and the other end connected to the power source 12, and is energized. This is an operating relay that closes the door 2 and the landing door 8 and also starts the car.

In the elevator operation system configured as described above, when the driver 6 gets into the car 1 and stands in front of the in-car operation panel 5, the receiver 7b of the driver absence detection device 4 detects a reflected wave. Therefore, the detection contact 15 is opened. When the driver 6 closes the changeover switch 13, the driver-operated relay 14 is energized by the circuit 11-13-14-12, and the normally open contacts 14a and 14b are closed. Even if the normally open contact 14a is closed, the detection contact 15 is opened before that, so the operation prevention relay 16 is not energized. Therefore, the normally open contact 16a is opened and the normally closed contact 16b remains closed. When a car call is registered by the in-car operation panel 5 and a hall call is registered by the hall button 10, the call detection contact 19 is closed. When the operation button 18 is pressed at this time, the operation relay 20 is activated to 11-18-14b-19-16b-20.
-12 circuit closes the car door 2 and the landing door 8, and also starts the car 1. Car 1 stops at the next registered floor, and car door 2 and landing door 8
open. Here, the opening/closing of the car door 2 and the landing door 8, and the starting/stopping of the car 1 are well-known techniques, and the explanation thereof will be omitted. As mentioned above, the driver 6 operates the in-car operation panel 5.
The operation of car 1 can continue as long as the person is standing directly in front of the car.

Next, assume that the driver 6 leaves the car 1 while the driver-operated relay 14 is energized. Then, since the receiver 7b no longer detects the reflected wave, the detection contact 15 is closed. The operation prevention relay 16 is energized by the circuit 11-15-14a-16-12, and its normally open contact 16a is closed and self-held. Also, since the normally open contact 16b is open, even if the operation button 18 is pressed, the operation relay 20
is never energized. Therefore, car 1 does not start. Driver 6 gets into car 1 again,
When the user stands at the front of the in-car operation panel 5 and opens the operation prevention release switch 17, the self-holding circuit of the operation prevention relay 16 is cut off. Furthermore, since the detection contact 15 is open, the operation prevention relay 16 is deenergized. At this time, if there is a floor with a registered call, the call detection contact 19 is closed, so the operation button 1
When 8 is pressed, car 1 is activated and operation can be resumed. As mentioned above, when driver 6 leaves car 1, car 1 is prevented from driving, so car 1
Even if the car is left open so that it can be operated by an unspecified number of people, no one will be caught between the car door 2 and the landing door 8, and the car 1 will not be used for private use. do not have.

FIG. 3 shows another embodiment of the invention. Since this invention prevents the car 1 from being driven, it is not preferable to leave the car 1 in a state where the car 1 is not driven for a long period of time because it will disrupt traffic within the building. In such a case, it would be desirable to notify the necessary locations of the prohibition of driving, assuming that a replacement driver would be dispatched. Figure 3 shows an improvement on this point.

In the figure, 16c is a normally closed contact of the operation prevention relay 16, 21 is a signal device with a flicker function that periodically repeats opening and closing of the contact, 22 is a cam attached to the car 1, and 23 is attached to the hoistway. Similarly, 24 is a position switch for the second floor, 25 is a position switch for the third floor, and 26 is a position switch for the elevator hall or the building where the manager is located. This position indicator is provided in the management room and is composed of indicator lights 26a to 26c that indicate the position of the car 1.

Now, if car 1 is stopped on the second floor, the indicator light 26b is 11-16c-24-26b-12.
It lights up with this circuit. At this time, operation prevention relay 1
6 is energized, the contact 16c is opened, and the indicator light 26b blinks as the signal device 21 opens and closes. This notifies the elevator hall 9 or the building management office that the car 1 is inoperable on the second floor.

FIG. 4 shows yet another embodiment of the invention. The driver 6 is usually located just in front of the in-car operation panel 5, but it is also common for him to go out into the elevator hall 9 for a short time to guide passengers. If the operation of car 1 is prevented even for such a short period of absence, the operation prevention release switch 17 must be activated each time.
must be operated. Figure 4 shows an improvement on this point.

In the figure, the same symbols as in FIG. 2 indicate the same parts. 2
7 is a time limit relay, 27a is a contact point of this time limit relay 27, and the time limit relay 27 is energized for a predetermined time (i.e., the time when the driver 6 is away from the front of the in-car operation panel 5 as a normal operation). It is a time-limited normally open contact that closes after a period of time greater than Note that one end of the time limit relay 27 is connected to the power source 11 via the detection contact 15. The normally open contact 27a for time-limited operation is connected in parallel to a circuit in which the operation inhibit release switch 17 and the normally open contact 16a of the operation inhibit relay 16 are connected in series.

If the driver 6 is now in front of the in-car operation panel 5, the detection contact 15 is open, so the time limit relay 27 is deenergized, and the normally open contact 2 of the time limit operation is deenergized.
7a remains open, so the operation prevention relay 16 is not energized. Also, driver 6
time-limited relay 2 away from the front of the in-car operation panel 5.
7 is energized, but if it returns to the front of the in-car operation panel 5 again before the time-limited normally open contact 27a is closed, the time-limit relay 27 is de-energized again, so the operation prevention relay 16 is activated. You will not be forced to do so. but,
When the driver 6 leaves the front part of the in-car operation panel 5 for a long time and the normally open contact 27a of the time-limited operation of the time-limited relay 27 is closed, the operation prevention relay 16 switches to the terminal 11-27a.
-14a-16-12 circuit is energized and its contacts 16b are opened so that the car is prevented from operating. As described above, even if the driver 6 leaves the in-car operation panel 5 for a short time, the operation can be continued.

In the above embodiment, an ultrasonic transducer is used as the driver absence detection device, but a load detection device that detects the load loaded on car 1 is used to detect the load loaded on car 1. By detecting that the number is zero, it may be assumed that the driver 6 has left the car 1. That is, it may be determined that the driver is absent when the load inside the car becomes zero even though the changeover switch 13 is operated and the car is in the driver-operated state. Alternatively, it may be assumed that the driver 6 leaves the car 1 when it is detected that there are no passengers in the car 1 by capturing an image of the passenger in the car 1 using an industrial television and processing the image.

As described above, this invention is designed to prevent the car from operating when it is detected that the driver is not in the elevator operated by the driver. This has the effect of preventing the car driven by the driver from being driven by an unspecified number of people.

Further, when the elevator is in a state where the operation is blocked, by notifying the building management room or the elevator hall, there is an effect that the manager can be notified quickly of the state where the operation of the elevator is blocked.
