[Problems to be solved by the invention]

In the elevator operating apparatus having the above-described opening / extending control circuit, when the opening / extending button is turned on, the elevator of that car does not participate in the group management operation for a predetermined time (for example, 2 minutes). Even if a landing call common to elevators occurs, the units out of operation management cannot respond to the landing call, the group management performance deteriorates, the waiting time for the hall passengers increases, and the service deteriorates significantly.

The present invention has been made to solve the above problems, and provides an elevator driving device capable of preventing deterioration of group management performance and deterioration of service to passengers at a hall even if the open / extend button is operated. The purpose is to do.

[Means for solving problems]

The elevator driving apparatus according to the present invention includes means for detecting a setting condition for invalidating the operation of the door opening time extension button, and means for canceling the door opening time extension by the operation of the detection means. It is equipped with and.

[Action]

In the present invention, when the detecting means detects the setting condition for invalidating the opening extension operation, the door opening time extension releasing means operates and releases the operation of the opening extension button. Therefore, a plurality of elevators are operated as a group. The group management performance to be managed does not deteriorate, and it is possible to prevent deterioration of service to passengers in the hall.

〔Example〕

 An embodiment of the present invention will be described below with reference to FIG.

Fig. 1 shows a circuit diagram that enables three elevators similar to the case of Fig. 2 to perform door opening time extension control and its invalidation control under group management operation. Button
1, its operation relay 1A and timed relay 1B, open extension button 2 for No.2, its operation relay 2A and timed relay 2B, open extension button 3 for No.3, its operation relay 3A and timed relay 3B are shown in FIG. It has the same configuration as.

Reference numeral 4 is a detection circuit for detecting a predetermined setting condition for invalidating the door opening time extension operation of each unit. This detection circuit 4 is used to open each of the extension extension button operation relays 1A, Normally open contacts 1Ab, 2Ab, which are closed when 2A, 3A are energized
Operates by detecting that the AND condition of 3Ab is satisfied and that the output contact 5 of the waiting time excess signal circuit (not shown) that operates when the average waiting time of each floor gets over the set value To do. Further, 6 is a door opening time extension button operation release relay (hereinafter simply referred to as an open extension button operation release relay) that is energized when the detection circuit 4 operates. +),
The normally-closed contacts 6a, 6b, 6c are connected between (-) and the open extension button operation relays 1A, 2A, 3A of Units 1 to 3 and the timed relays 1B, 2B, 3B connected in parallel to them. Commonly connected to the power circuit.

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

For example, if only the open extension button 1 of Unit 1 is turned on, the open extension button operation relay 1A of Unit 1 is energized by the closed circuit of (+)-1-6a-1A-(-), and at the same time, relay
Since 1B also starts operation, Unit 1 enters the door extension time extension operation. At this time, the normally-open contact 1Aa of the open / extend button operation relay 1A is closed, but the open / extend button operation relays 2A, 3A of Units 2 and 3 are closed.
No. is not energized and the output contact 5 of the waiting time excess signal circuit is not closed, so that Unit 1 continues to be in the door open state for a predetermined time by the timed relay 1B.

However, after that, if the average waiting time of the passengers on the hall exceeds the set value (for example, 40 seconds), the waiting time excess signal circuit operates,
Since the output contact 5 forms a closed circuit, (+)-5-6-
The (-) closed circuit urges the open / extend button operation release relay 6 to open its normally closed contacts 6a-6c. When the normally-closed contact 6a is opened, the opening / extending button operation relay 1A of the No. 1 machine is deactivated, the opening / extending button operation of the No. 1 machine is canceled on the way, and the normal operation is resumed.

When all the extension extension buttons 1, 2 and 3 of Units 1 to 3 are turned on, each extension extension button operation relay 1A, 2A, 3A
Are both energized and the normally open contacts 1Ab, 2Ab, 3Ab are closed, so the (+)-1Ab-2Ab-3Ab-6-(-) closed circuit energizes the open extension button operation release relay. When the normally closed contacts 6a-6c are opened, the open / extend button operation relays 1A, 2A, 3A of Units 1, 2 and 3 are deenergized, and the open / extended button operations of all Units are released The operation is returned to normal group management operation.

Therefore, if all the extension extension buttons 1 to 3 of Units 1 to 3 are turned on or the average waiting time of the hall passengers exceeds the set value, the operation of the extension extension buttons is automatically canceled and the group management operation is forcibly restored. Therefore, the group management performance is not impaired as in the conventional case, and the service to the hall passengers is not deteriorated.

In the above embodiment, the open / extend button has been described, but another device for maintaining the door open state, for example, the open / extend switch may be used. Further, in the above embodiment, the case where the number of elevator groups managed is three has been described, but the same applies to a case where the number of elevators managed is three or more.

〔The invention's effect〕

As described above, according to the present invention, even if the elevator extension button is operated, the setting condition for invalidating it, that is, the door opening time extension button of all elevators is operated,
When it is detected by the detection means that the average waiting time of each floor hall passenger of each elevator exceeds the set value,
Since the opening means is operated so as to invalidate the opening / extending button operation, the elevator group management performance is not deteriorated and the service to the passengers at the hall can be prevented from being deteriorated.
