Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a signaling device for a plurality of elevator cars operated in a fixed mutual positional relationship.

Recently, double-decker elevators (hereinafter referred to as double-decker elevators) have been increasingly used for the purpose of increasing the transportation capacity of elevators in the same space.

In a double deck elevator, the traffic demand (load) between the upper and lower cars may become unbalanced.

For this reason, when a double deck elevator decelerates to service a certain floor, there are cases where only a call corresponding to the upper car/1-car is generated and a call corresponding to the lower car is not generated.

Further, when the vehicle reaches the destination floor in such a state, only the door of the upper cage may be opened and closed, and the door of the lower cage may remain closed.

Therefore, when the elevator decelerates, passengers in cages that are not being called may feel uneasy.

SUMMARY OF THE INVENTION An object of the present invention is to provide an elevator signaling system that eliminates the above-mentioned drawback of giving passengers a sense of anxiety.

The figure shows a circuit configuration diagram of one embodiment of the elevator signaling device of the present invention, and takes an example of a double deck. In this figure, the alphabet A is attached to the contact point corresponding to the upper car, and The alphabet B has been added to the corresponding contact point codes to standardize them.

In addition, normally closed contacts are indicated by squares, and normally closed contacts are indicated by squares.

The symbols, names, and functions in this figure will be described below.

A: 21-rule cage B: Lower cage LA: A display device for the upper cage that, when connected to the power supplies P and H, displays some kind of display to relieve passengers' sense of anxiety.

LB: A display device for the lower cage that, when connected to the power sources P and H, provides some kind of display to relieve passengers' anxiety.

15-1, 15-2: Contacts that open at the same time as the travel command and close at the same time as the stop.

10A1.10A2: Upper cage door close detection relay contacts that are energized when the upper cage door is closed.

10B1.10B2: Lower cage door close detection relay contacts that are energized when the lower cage door is closed.

90A1.90A2: Contact of the upper car deceleration relay that is energized when a call is generated in the upper car and the double deck elevator is decelerated to respond to the call.

90B1.90B2: Contacts of the lower car deceleration relay that are energized when the double deck elevator decelerates to respond to a call on the lower car.

In the above configuration, assuming that only the calls corresponding to the upper car of the double deck elevator are occurring,
The deceleration relay for the upper cage is energized (at this time, the call corresponding to the lower cage is not generated, so the deceleration relay for the lower cage is not energized), and its contact 90A1 is closed.
Since the lower cage door closing detection relay is already energized and its contact 10B1 is closed, the lower cage display device LB operates.

This display device LB displays, for example, "Please wait.

” or “Upper cage is in service.

”, etc. Then, when the double deck elevator arrives at the floor where the double deck elevator is located, only the door of the upper cage A is opened and closed until the door is completely closed.
B continues its operation.

Therefore, it is possible to display a signal that does not make the passengers in the car who are not called feel uneasy already at the time when the elevator starts to decelerate.

In addition, in the above-mentioned embodiment, a signal that does not give a feeling of anxiety is displayed only in the lower cage, but if the situation is reversed, a signal that does not give a feeling of anxiety is displayed in the upper cage. Needless to say, it will become.

Also, after arriving at a floor with a double deck elevator and opening the doors of both the upper and lower cages, the service for one cage may end earlier and close first.

In this case as well, although it is instantaneous, it causes anxiety to the passengers on the side where the cage door is closed.

In the embodiment described above, the display device is configured to operate even in such a case.

In the figure, if you arrive at the floor where the double deck elevator is and both the upper and lower cages open and close their doors, for example, if the lower cage completes service earlier than the upper cage and the door closes, the lower Contact 10B1 of the cage door closing detection relay closes.

At this time, assuming that the upper cage has finished its service and the chair door is open, contact 1 of the upper cage door close detection relay
Since 0A2 is closed (contact 15-2 is also closed), lower cage display device LB operates and provides the same guidance as above.

When the upper car finishes its service and the door closes, the contact 10A2 of the upper car door close detection relay opens, the signal disappears, and the double deck elevator departs to respond to another call.

Therefore, even if the elevator does not depart, passengers in the cage with the door closed will not feel uneasy.

Note that the elevator signaling device of the present invention is not limited to use in double-deck elevators, but can also be used in, for example, crane-type elevators in which cages are provided at both ends of the hoisting rope.

According to the present invention, in an elevator in which the operation of a plurality of cars whose mutual positional relationship is fixed is controlled, when the elevator decelerates even though there is no call to the car, the car feels uneasy. Since it displays a signal that would not be given, the passengers in the cage will not feel anxious.

[Brief explanation of drawings]

The figure shows a circuit configuration diagram of an embodiment of the elevator signal device of the present invention.
