Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for exclusively operating a specific elevator car.

When a plurality of elevator cars are arranged in parallel, the cars are operated by a common hall call registered by a hall button and an independent car call registered within each car.

That is, when four cars a to d are installed as shown in FIG. 1, hall buttons A and B are used to register a hall call common to all four cars a to d.

Therefore, it is not possible to specifically call any one car using the hall buttons A and B.

Incidentally, recently there has been a demand for dedicated operation in which a specific person, such as an executive, is transported exclusively by a specific car, or a specific person is placed in service on a dedicated floor.

Therefore, in addition to the above-mentioned general hall buttons A and B, a specific hall button C is provided separately, and when switching to dedicated operation with the separately provided dedicated operation switch, the car d is called by the general hall buttons A and B. , and is placed under the control of landing button C.

That is, the car d is operated exclusively for responding only to hall calls made by the hall button C and car calls registered within the car d.

However, even if the dedicated operation switch is operated, when a car call is registered in car d, car d will stop at that floor, so it will take a considerable amount of time to actually enter dedicated operation.

Additionally, if a train stops on a dedicated floor (a dedicated floor subject to dedicated operation) with a general passenger on board, the general passenger and the dedicated passenger may run into each other, which can make both parties uncomfortable.

The present invention aims to improve the above-mentioned drawbacks, and aims to provide an elevator operation device that quickly shifts to dedicated operation when a dedicated operation switch is operated, and eliminates problems that occur during that time. purpose.

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

In Fig. 2, 1a to 9a are car call buttons provided in car d to register car calls using destination buttons for floors 1 to 9, 1b to 9b are AND gates, 1C to 9C are recording devices,
ICa to 9Ca are the outputs of the storage devices 1c to 9c, respectively, and are car call registration signals for the 1st to 9th floors, 1d to 9d are car position signals that become "1" when the car d approaches the 1st to 9th floors, and 10 11 is a call response completion signal that becomes "1" when the car d completes responding to all of its car calls; 11 is a dedicated operation signal that becomes "1" when the dedicated operation switch mentioned above is operated; 12.13 is a dedicated operation signal that becomes "1" when the dedicated operation switch described above is operated; AND gate, 14 is an inverter gate, 15 is a storage device, 16 is an OR gate, 17 is a detection circuit that enables stopping by a general hall call using hall buttons A and B, and 18 is a detection circuit that enables stopping by a special hall call using hall button C. This is a detection circuit that makes it possible.

In normal times, the dedicated operation signal 11 is "0", so the output of the inverter gate 14 is "1".

The detection circuit 17 becomes effective, and cars a to d can be stopped by a common hall call using hall buttons A and B.

Further, since the output of the AND gate 13 is "0", the detection circuit 18 is disabled, that is, the hall button C is disabled.

Further, the output of the OR gate 16 is "1", and the AND gates 1b to 9b are open.

Therefore, the car call buttons 1a to 9a in car d are valid.

For example, when the car call button 9a on the 9th floor is pressed, the AN
The output of the D gate 9b becomes "1", the storage device 9c is set, the car call registration signal 9ca becomes "1", and the car d stops at the 9th floor.

When the car d approaches the 9th floor, the car position signal 9d becomes "1".
, and the storage device 9c is reset.

It goes without saying that the other cars a-c can also be stopped by each car call.

Here, the dedicated operation switch is operated, and the dedicated operation signal 1
When 1 becomes "1", the output of the inverter gate 14 becomes "
O'', the detection circuit 17 becomes inactive, and the car d is placed outside the management of hall calls by hall buttons A and B.

The storage device 15 remains reset even when the reset signal becomes "0".

Therefore, the output of the OR gate 16 is "0" and the AND
Since the output of the gate 13 is also "0", the detection circuit 18 is invalid, and the car d is not placed under the control of the hall call by the hall button C.

Also, since the output of the OR gate 16 is "0", the AND game ~9b is closed, and after that, the car call button 1a
Even if ~9a& is pressed, the storage devices 1c to 9c are not set.

In other words, registration of a new car call becomes impossible.

Therefore, the car d has been set among the storage devices 1c to 9c by then, and the car call registration signals 1ca to 9ca are "
It will stop only on the floor that was set to 1.

In this way, when the response to all calls registered before the dedicated operation switch is operated is completed,
The car call response completion signal 10 becomes "1".

Now all the inputs of AND gate 12 are "1",
The output becomes "1" and the storage device 15 is set.

Now, the output of the OR gate 16 becomes "1", and the AND
The output of the gate 13 becomes "1", the detection circuit 18 becomes valid, and the car d is placed under the control of the hall call by the hall button C.

Therefore, it becomes possible to respond to a hall call on a dedicated floor.

Also, since the output of the OR gate 16 has become "1", A
The ND gates 1b to 9b are opened again, and car calls can be registered.

In other words, registration of new car calls and dedicated hall calls is prevented from the time the dedicated operation switch is operated until the car actually shifts to dedicated operation, so car d can quickly shift to dedicated operation. .

Then, from now on, car d will be called by the landing button C,
If it is registered in the car d, it will be operated exclusively depending on the call number.

Note that when car d stops due to a car call that has already been registered, if it is on a dedicated floor, dedicated passengers may get on the elevator, misunderstanding that the elevator has already been switched to dedicated operation.

In order to prevent this, it is desirable to display or announce the switching inside the steam car at the landing.

In other words, it would be more kind to passengers if they were instructed not to board the car at the landing because the car will be switched to dedicated operation, and to get off the car as soon as possible.

Further, in this case, the arrival forecast light that predicts the arrival of a car may not be turned on.

FIG. 3 shows another embodiment of the present invention, in which 1e to 9
20 is an AND gate, and 20 is a detection circuit that enables a stop due to a car call registered in car a.

Now, the exclusive floors will be the 1st and 9th floors.

The dedicated operation switch is operated in the same way as in Fig. 2, and the O
When the output of R gate 16 becomes "0", AND gate 1
e to 9e are closed.

Therefore, even if the car call on the 9th floor has been registered and the storage device 9c has been set by then, the AN
Since the output of the D gate 9e does not become "1" and is not input to the detection circuit 20, the car d does not stop at the 9th floor.

Similarly, on other dedicated floors, the train does not stop when called.

Therefore, special customers waiting at the landing on the dedicated floor and general customers inside the car will no longer run into each other.

If a car call for a floor other than the dedicated floor, for example, the 5th floor, is registered, the output of the storage device 5c is input to the detection circuit 20, so it is possible to stop at the 5th floor.

Although the example above is shown in which the car does not stop at a dedicated floor even if a car call is registered, it is also possible to cancel car calls on a dedicated floor until the car is completely switched to dedicated operation.

At this time, if a hall call for a dedicated floor is not registered, the car may be stopped by a car call.

Note that when the car d completes responding to all the registered car calls and the completion signal 10 becomes "1", the car calls on the dedicated floor are canceled all at once, although details are not shown.

In this example, the storage device 9c is reset.

As explained above, in this invention, when the exclusive operation switch is operated, registration of idle car calls and responses to hall calls on the exclusive floor are blocked until all car calls registered up to that point have been answered. I decided to do this, so
It is possible to shift to dedicated operation at an early stage.

Furthermore, since the registration of car calls for exclusive floors is prevented, it is possible to reduce the number of run-ins between general customers and exclusive customers, thereby reducing the chances of both parties feeling awkward.
