Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a device for registering elevator car calls.

In elevators installed in department stores and the like, car calls are fixed as necessary. Fixing car calls means continuing to register the car calls for the required floor when there are events or planned operations in the store, and it is suitable for operating elevators in department stores, etc. can. That is, if there is an event, repeated service to the event hall floor is required. Therefore, once a car call is fixed, even if the car is serviced on that floor and the car call is released, the car call will be registered again when the car leaves that floor, so it cannot be used on other floors. Once the service is finished, the service on the above floor will be performed again.

Conventionally, as is well known, elevators in department stores are equipped with a driver, and this driver fixes the car call for any floor based on instructions from the building manager.

However, in order to save labor, department stores are no longer able to always provide a driver for each cart. For this reason, the building manager is forced to take over the task of fixing the car calls, which burdens the manager with extra labor. Also, it is difficult to do this while the elevator is operating due to the concern for passengers, and although it may be possible to do this before the store opens, it is inconvenient that it cannot be changed freely while the elevator is operating. The reality is that car calls cannot be easily fixed for the reasons mentioned above.

This invention improves the above-mentioned problems, and aims to provide an elevator car call registration device that allows car calls to be easily fixed without bothering the labor of a driver, manager, etc.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 5.

In Figures 1 and 2, 1A to 3A are the destination floor buttons for the 1st to 3rd floors provided in the car of car A;
B~3B are the destination floor buttons of B car, 1C~
3C is a car call registration light built into the destination floor buttons 1A to 3A on the 1st to 3rd floors, and when lit, indicates that a car call has been registered. 1D to 3D are also built into the destination floor buttons 1B to 3B. The car call registration lights 4A and 5A are the down and up direction lights of car A, and 4B and 5B are the down and up direction lights of car B.

In Figure 3, 1E to 3E are car call fixed floor command buttons on the 1st to 3rd floors provided in the manager's room for both cars A and B, and 6 is also ``A'', ``OFF'',
``B'' is a 3-point car selection switch, and 7 is a 3-point car call fixed command switch with ``Fixed'', ``OFF'', and ``Release''.

In Figures 4 and 5, (+) and (-) are DC power supplies, 1F to 3F are car call fixed floor command relays for the 1st to 3rd floors, 1Fa to 3Fa are their normally open contacts, 1G
~3G is the car call registration relay on the 1st to 3rd floors of Unit A, and 1Ga to 3Ga are its normally open contacts, 1H to 3H.
is also a fixed car call relay, 1Ha~1Hb~
3Ha to 3Hb are normally open contacts, 1I to 3I are car position contacts that open when the A car reaches the 1st to 3rd floors, respectively, 10 is the A car selection relay, and 10a to 1
0c is its normally open contact, 10d is also its normally closed contact, 1
1 is the B car selection relay, 12 is the car call fixed command relay, 12a and 12b are its normally open contacts, 12
Similarly, c is a normally closed contact, 13 is a car call fixing release relay, 13a is its normally open contact, 14 is a car call fixing release command relay, 14a is its normally closed contact,
15 to 23 are backflow blocking diodes.

In addition, in FIG. 5, a similar one is provided for the B machine.

Normally, when the destination floor button 2A on the second floor is pressed in the car of car A, (+)-14a-10d・1
The second floor car call registration relay 2G is energized by the circuit 2c-16-2A-2I-2G-(-), and is self-held by closing the contact 2Ga. At the same time, the car call registration light 2C lights up. The second floor car call is now registered, and the car runs according to a well-known elevator operation circuit (not shown). When the car reaches the second floor, the car position contact 2I is opened, so the car call registration relay 2G is deenergized, the contact 2Ga is opened, and the car call registration light 2C is turned off. This will cancel the car call on the second floor. The same applies to other floors.

Next, when the manager turns the machine selection switch 6 to the "A" side, the machine A selection relay 10 is energized, contacts 10a to 10c are closed, and contact 10d is opened. Next, when the car call fixed command switch 7 is turned to the "fixed" side, the car call fixed command relay 12 is energized, contacts 12a and 12b are closed, and contact 12c is opened. When the second floor car call fixed floor command button 2E is pressed in this state, the second floor car call fixed floor command relay 2F is energized and the contact 2
Fa is closed. Now (+)-14a-10b
-12a-2Fa-2H-22-12b-10c
The second floor car call fixed relay 2H is energized by the - (-) circuit and self-holds by opening the contacts 2Ha and 2Hb. Also (+)-14a-10b-
The car call registration relay 2G on the second floor is also energized by the circuit 12a-2Fa-2I-2G-(-).
(+)-(14a-2Hb-19-2I-2G-
It is held by the (-) circuit. Further, the car call registration light 2C is also lit and maintained.

After this, if the second floor is the only floor on which you want to fix the car call, turn the car selection switch 6 and the car call fixation command switch 7 to the "OFF" side, and then the car A selection relay 10 and the car call fixation command relay 1
2 is deenergized, and the contacts 10a to 10c, 12a, 1
2b is open, and contacts 10d and 12c are closed.
By opening the contacts 10b and 12a, car calls on other floors can no longer be fixed (car calls on the second floor continue to be fixed). Furthermore, when the manager fixes the car call for any floor, even if there is a car call that has already been registered or a car call that was registered by pressing destination floor buttons 1A to 3A in the car, the contact 10
Since d and 12c are open, there is no possibility that these car calls become fixed.

Now, when the car is serviced to the second floor, the car position contact 2I is opened, so the second floor car call registration relay 2G is deenergized.

However, since the car call fixed relay 2H is held, if the car leaves the second floor, the car position contact 2I
When closed, (+)-14a-2Hb-19-2
The second floor car call relay 2G is energized again by the I-2G-(-) circuit, and the second floor car call is automatically registered. By opening the contacts 10d and 12c, it becomes possible to register a car call on a floor other than the second floor, so that the second floor, where the car call is fixed, and the other floor, where the call is registered, are serviced.

Using a similar procedure, it is also possible to remotely fix car calls on any floor of car A. Furthermore, if the car call selection switch 6 is turned to the "B" side while the car call fixing command switch 7 is kept on the "fixed" side, the car call on any floor of the B car can be fixed remotely, as described above.

Next, while keeping the car selection switch 6 in the "A" side, the car call fixed command switch 7 is "released".
When the car is turned on, the car call release relay 13 is energized and the contact 13a is closed. with this,
The car call lock release command relay 14 is energized by the circuit (+)-10a-13a-14-(-), and the contact 14a is opened. As a result, the car call fixed relay 2H on the second floor and the car call registration relay 2G are deenergized, and the fixation of the car call is released.
Car call fixing is released for Car B using the same procedure.

In the example, two cars were explained, but three
It is obvious that the invention can be applied to more than just a stand.

Further, fixing or canceling a car call may be notified to any car.

In addition, one set of car call fixed floor command buttons 1E~
Although the explanation has been made regarding fixing or releasing a car call using 3E, it is also applicable to registering a remote car call during maintenance or when calling a car to an arbitrary floor.

As explained above, in this invention, when the car call fixed command device installed at a location other than the car is operated, a car call on a specific floor is registered, and even after the car responds to that floor, the registration of this car call is continued. Since the car call continues, the car call can be easily fixed without the need for the driver or manager to operate it inside the car.

In addition, one set of car call fixed command devices is used to register car calls for specific floors for each of multiple cars, and to continue this process.
The manager can centrally manage the fixing of car calls and can be configured economically.
