The series circuit with Aa is connected in parallel to the open extension button 1.

In addition, 2 is a door opening time extension button (hereinafter simply referred to as the opening extension button) provided in the car of No. 2, and 2A is an operation relay for the opening extension button of No. 2. These opening extension button 2 and its operation relay 2A are Connected in series between DC power supplies (+) and (-). 2B is a time limit relay for the second machine that operates after a certain period of time (for example, 2 minutes) when energized, and this time limit relay 2B is connected in parallel to the open extension button operation relay 2A,
Furthermore, the normally closed contact 2Ba and the open extension button operation relay 2
A series circuit with the self-holding normally open contact 2Aa is connected in parallel to the open extension button 2.

Next, the operation will be explained.

When the opening extension button 1 of the No. 1 machine is turned on, (+)-1-
IA-(-) closed circuit opens extension button operation relay I of Unit 1
A is energized and its contact IAa is closed, thereby self-maintaining, and the door of the first machine is maintained in an open state by the door control device of the first machine (not shown).

On the other hand, the time limit relay IB of the No. 1 machine starts counting the time limit from the time when the opening extension button 1 is turned on, and when the count of a certain time ratio (for example, 2 minutes) is completed, the time limit relay IB operates and its normally closed contact IBa opens, opening extension button operation relay I
A is deenergized and the door control device releases the open state of the protrusion of Unit 1, returning to normal operation.

The same operation is performed when the opening extension buttons 2 and 3 of the second machine are turned on. Therefore, the explanation of its operation will be omitted.

As described above, when the opening extension button is turned on, the opening extension operation of the elevator of that car is performed for a predetermined time period without being involved in group management operation.

(Problem to be Solved by the Invention) In the elevator operation device having the opening extension control circuit as described above, when the opening extension button is turned on, the elevator of that number is operated for a predetermined period of time (2 minutes) by group control. Since it will not be involved in the operation in any way, even if there is a common hall call for each elevator, the elevator whose operation is not controlled will not be able to respond to the hall call.
There was a problem that group management performance deteriorated, waiting time for passengers at the landing increased, and service deteriorated significantly.

This invention was made to solve the above-mentioned problems. It enables appropriate group management operation even when the extension button is operated, improves the usability of the extension button, and improves the usability of the extension button. The object of the present invention is to provide an elevator operating device that can prevent service deterioration.

[Failure to solve the problem]

The elevator operating device according to the present invention includes a number limiting means for limiting the number of elevators whose door opening time extension buttons can be operated among a plurality of group-managed elevators to a predetermined number or less; and a notification means for notifying the inside of the elevator car other than the opening extension that the elevator car is in operation.

[Operation] In the present invention, when the door opening time extension button of an elevator whose operation is managed as a group is turned on, the elevator of that elevator continues to operate the opening extension button for a certain period of time, and the number limiting means is activated. The operation of the door opening time extension button for the remaining predetermined number of vehicles is disabled and placed under group control. Therefore, the group management performance does not deteriorate, and it is possible to prevent the deterioration of service for passengers at the landing. In addition, since the elevator of the number whose door opening time extension button is turned on is in use for extension extension, it is notified to the notification means of other elevators whose opening extension operation has been disabled, so group control is performed based on the content of the notification. The opening extension status of the elevator is grasped, and those who wish to extend the opening time can easily use the opening time extension button, and appropriate group management operation is enabled.

〔Example] Embodiments of the present invention will be described below with reference to the drawings.

Figure 1 shows a circuit diagram in which two elevators, similar to the case in Figure 3, are operated under group management, enabling door opening time extension control, operation restriction and notification control of the opening extension button. Opening extension button for No. 1 machine 1. Its operating relay IA and timed relay 1B, opening extension button for No. 2 machine 2. The operation relay 2A and the time limit relay 2B have the same structure as in FIG. 3.

In addition, 3 is a door opening time extension button operation restriction relay (hereinafter referred to as an opening extension button operation restriction relay) that disables the operation of the other opening extension button when one of the two group control elevators is operated. ), this relay 3 is connected to the DC power supply (+ ), (-) are connected. 3
A and 3b are normally closed contacts of the open extension button operation limit relay 3, respectively, and are connected in series to the open extension button 1 of the first machine and the open extension button 2 of the second machine. 4 is the opening extension button 2 of the 2nd machine
This is a warning light that notifies the elevator car of No. 1 that the elevator of No. 2 is in operation to extend its opening when turned on.
DC type 'rA(+) through the normally open contact 2Ac of A,
Connected between (-). 5 is the opening extension button 1 of the first machine
This is a warning light that informs the elevator car of No. 2 that the opening extension button of No. 1 is being extended by turning on the button. DC power supply (+), (-) via normally open contacts IAc
connected between.

Next, the operation of this embodiment configured as above will be explained.

For example, if the opening extension button 1 of the No. 1 machine is turned on, the opening extension button operation relay IA of the No. 1 machine is energized by the closed circuit of (+) -1-3a-IA-(-), and the contact IAa At the same time as self-holding, the time limit relay IB also starts operating, so the No. 1 machine begins to extend the door opening time. At this time, the normally open contact IAc of the open extension button operation relay IA is closed, so the notification light 5 of Unit 2 lights up in the closed circuit of (+) -1Ac-5-(), which causes [other elevators A message such as "Please wait for a while while the elevator is being extended" is displayed inside the car of No. 2 to notify passengers in the car that the elevator of No. 1 is being extended.

On the other hand, the normally open contact IA of the open extension button operation relay IA of Unit 1
b is closed, the open extension button operation restriction relay 3 is energized by the closed circuit of (+)-1Ab-3-(-), and the normally closed contact 3b is opened, so that the operation of the second unit is activated. The energizing condition circuit of the opening extension button operation relay 2A is opened, and the ON operation of the opening extension button 2 of the No. 2 machine is disabled. That is, the No. 2 elevator is placed under group control, and both elevators are prevented from being extended. In addition, when the time limit set in timed relay IB of No. 1 machine ends, timed relay IB
operates, and by opening its normally closed contact IBa, the operation relay IA is deenergized and the notification light 5 is extinguished. Therefore, after that, the opening extension button 2 can be operated in the second machine.

In addition, when the extension button 2 of the No. 2 car is turned on, it operates in the same way as in the case of the No. 1 car, and the opening extension button 2 of the No. 2 car is displayed on the notification light 4 in the elevator car of the No. 1 car. At the same time, the operation of the opening extension button 1 of the No. 1 machine is disabled.

Therefore, in the above embodiment, when the opening extension button of one elevator is turned on, the operation of the opening extension button of the other elevator is disabled so that the other elevator cannot perform the opening extension operation. As a result, the other elevator can serve passengers at the hall under group control, and this eliminates the problem of not being able to respond to hall calls as in the conventional system. In addition, when one of the elevator car opening extension buttons is turned on, it is possible to grasp the current opening extension status of the group control elevator while displaying a notification light on the other elevator car. It becomes easier for the person who operates the opening extension button to utilize the opening extension of the elevator.

FIG. 2 is a circuit diagram showing another embodiment of the invention.

In FIG. 2, parts indicated by the same reference numerals as in FIG. 1 have the same configuration, and the parts different from those in the first part will be explained with emphasis.

In FIG. 2, parts that are different from those in FIG. 1 are indicated by numerals 6 to 9. 6 is a counter for counting the release time of the opening extension operation provided in the car of No. 1, which counts the release time of the opening extension operation of No. 2 car, and the content of the count can be displayed on the display 8 connected to this counter. It looks like this. Also,
7 is a counter for counting the release time of the opening extension operation provided in the car of No. 2, which counts the release time of the opening extension operation of No. 1 car, and the contents of the count are displayed on the display 9 connected to this counter.
It is now possible to display.

In the circuit with the above configuration, for example, the opening extension button 1 of machine No. 1
is turned on and its operation relay IA is energized, the normally open contact IAc is closed, the notification light 5 lights up, the content written in the black box appears, and at the same time the counter 7 starts counting the remaining time for a certain time period (for example, 2 minutes). Counting contents of counter 7 (
(remaining time) is output to the display 9 to display the remaining time. Therefore, if someone operates the opening extension button 2 in the car of No. 2, all they have to do is watch the display on the display 9 and wait for the opening extension operation of No. 1 car to be completed before turning it on.

In this embodiment, in addition to obtaining the same effects as the embodiment shown in FIG. This has the effect of being able to accurately grasp the opening extension button and further improving the usability of the extension button.

In addition, in the above embodiment, the opening extension button was explained, but
Other devices for maintaining the door open state, such as an opening extension switch, may also be used. Furthermore, in the above embodiment, the case where the number of group-managed elevators is two is explained, but the present invention can be similarly applied to a case where the number of group-managed elevators is three or more.

[Effects of the Invention] As described above, according to the present invention, when the elevator opening extension button is operated, it is notified to other elevator cars that the opening extension button is being operated, and the opening extension button is also activated. Since the elevator is configured so that the operation of the elevator can be limited to a predetermined number of elevators or less, the group management performance of the elevators is not degraded, and a decrease in the noise level for passengers in the hall can be prevented, and the opening extension button can be easily used.
