is open and the normally closed contact (16a-8) is also open, so
The door control relay (18-B) of Unit B is deenergized and the door of Unit B is opened.

Next, the operation during cooperative operation will be explained.

First, in Figure 1, when the cooperative operation switch (1) is turned on and the condition detection circuit (3) is configured, the cooperative operation command relay (2) is energized and self-maintained by closing the normally open contact (2a). Then, the normally open contacts (2b), (2c), and (2d) are also closed by the energization of the linked operation command relay (2).

), (+) -(2C)-(11-A)
-(t2a -B) -(12-A) The A master car relay (12-A) is energized by the circuit of -(-), and is self-maintained by closing the normally open contact (12a-A). In addition, the normally open contact (tzb-A) and the normally open contact (12c
mA) is closed, the contact (12d-A) in FIG. 3 is opened, and car No. A is set as the master car.

In the following, a description will be given of the cooperative operation in which Car No. A is used as the master car. Car B is loaded with luggage, the car call for the destination floor is registered, and the car is operated (the series of circuits such as call registration, running, and stop determination are well known and will therefore be omitted). When this B unit stops at the destination floor, the normally closed contact (4a-

On the other hand, in Figure 2, Unit A has a normally closed contact (12cmB
) is open, so the door opens and closes normally.

Furthermore, in Fig. 1, when the same floor stop detection relay (5) detects that A and B are stopped on the same floor, for example, if they are stopped on the 4th floor, both A and B are stopped. The floor switch (4F) is closed, and (◆

When the door open button (13-A) is pressed in car No. A, the door open button relay (14-A) is energized. In addition, in Unit B, the third
Since the normally closed contacts (5d) and (14b-A) in the figure are both opened, the door control relay (1B-B) is deenergized and the door of No. B car is opened.

A large amount of luggage was loaded into each of the A and B cars with the doors opened,
When this cargo is to be transported from the first floor, the carts that have been loaded are sequentially dispatched to the destination floor. Car No. A, which is set as the master car, arrives at the destination floor with an operator on board at the end. The door of the cooperative operation car (car B) other than the master car does not open even when it reaches the destination floor, but when the master car car A arrives and presses the door open button of the master car, the door opens. Therefore, the master car is safe because the cars operated in coordination will not open their doors inadvertently at the destination floor.

In the above embodiment, there are two elevators, A and B, but the present invention can also be applied to a case where there are two or more elevators. Furthermore, in group management where multiple elevators are grouped, a specific number of elevators within an arbitrary group may be targeted; for example, two of the four group managed elevators may be used. . In this case, during cooperative operation, it is common to prohibit group management operation from responding to isolated landing calls, etc.

Furthermore, multiple car calls can be registered in cars other than the master car, and the car can be made to wait on the floor where the car stopped at the nearest car.

In addition, the landing area may be equipped with an indicator light indicating that the train is in dedicated operation.

〔Effect of the invention〕

As described above, according to the present invention, during cooperative operation, the door opening operation of the cooperatively operated cars other than the master car is controlled by the door opening button of the master car. Since the door will not be opened inadvertently at the destination floor, the cargo can be transported efficiently, safely and effectively.
