Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a device for operating a plurality of elevators.

There is an assignment system group control elevator that selects the car most suitable for responding to a hall call, assigns a hall call to that car, and notifies this by lighting the assigned light of that hall.

In this type of elevator, a car that is assigned a hall call is
Even if another car responds earlier, the assigned hall call is serviced.

Therefore, in general, the above-mentioned hall call is not canceled even if a first-arriving car other than the assigned car is placed.

There is also a hall call indicator light (generally built into the hall button) that indicates that a hall call has been registered.

) remains lit.

In this way, because the assigned light and the hall call indicator light are on, even if a car other than the assigned one arrives first, the passengers waiting at the hall may not notice this, or may be slow to notice. It is possible that you could have boarded the first-arrival car, but now you are unable to do so.

In addition, even if you notice that the first car has arrived, the waiting passengers are already waiting in front of the landing where the assigned light is lit, so if you are far from that place and the landing of the first car, there is not enough time to board the car. We have to put in the effort.

At this time, some models allow you to reopen the door of the first-arriving car by pressing a nearby landing button, but the landing call indicator light is still lit, indicating the registration of the landing call. , I often give up on pressing the boarding button.

As a result, there were times when I had to wait for the next assigned car to be sent off, instead of getting into the first available car.

The present invention solves the above-mentioned drawbacks, and provides an elevator operating device in which when a car other than the assigned car arrives first, the door of the first-arrived car can be reopened by pressing the landing button, making it easy for passengers waiting at the landing to notice. purpose.

Waiting customers board the car by the end of a certain period of time.

When the above-mentioned time has elapsed, the time limit relay 17 is reset, the contact 17a is closed, the door control relay 18 is energized again, and the door begins to close again.

When the door is completely closed, the stop command relay contact 13c opens.
Arrival forecast light 2■ of Unit 2 goes out.

Unit 2 departs for the next called floor.

Eventually, when the No. 1 car also approaches the second floor and a stop command is issued, the stop command relay 13b is closed.

Since the car position contact 2Fb and the upward direction relay contact 11b are closed, (+) 2Ha-2H-2Fb-1
The uplink call assignment holding relay 2H is deenergized by the circuit 1b-13b-(to), and the contact 2Hb is opened.

On the other hand, ←)-11c-13c-14-2Fc-2I-(
A circuit is formed, and according to the opening and closing of the intermittent relay contact 14, the arrival forecast light 2■ of car No. 1 blinks to notify the arrival of the car.

The operation after the car stops is the same as in the case of No. 2 car.

In this way, when No. 2 car borrows 1 power before No. 1 car, which is assigned to the up call on the 2nd floor landing, all the up call indicator lights 2E on the 2nd floor go out, and the up call on the landing is called. By pressing button 2A, waiting customers will be informed that the door of Unit 2 can be reopened.

4 and 5 show other embodiments of the present invention, and FIG.
The figure is common to each machine, and Figure 5 is provided for each machine.

Please use Figure 3 in addition to this. In the figure, IDb to 8Db
are up call registration relays 1D to 8D for the 1st to 8th floors, respectively.
The normally open liquid 71 and IFf to 8Ff are the car position liquids 71Gb to 8Gb, 1Gc to 8Gc are the second
Contacts IGa to 8Ga in the figure are similar to the relay call assignment relay contacts for landings on the 1st to 8th floors, and IJ to 8J are stop detection relays for the 1st to 8th floors, respectively. IJa to 8Ja are the normally open contacts I.

When the No. 1 car is assigned to the up call on the 2nd floor, the up call assignment relay contact 2Gc is closed, and the 2nd floor up arrival forecast light -2■ of the No. 1 car is lit as an assignment light.

Here, when No. 2 approaches the second floor by car call and a stop command is issued, (G)-11e-13d-2F f-2
In the circuit J-(c), the second floor stop detection relay 2J is energized, the contact 2Jb-2 is opened, and the second floor up call indicator light 2 is activated.
All E lights go out.

Further, the contact 2Ja is closed, and the arrival forecast light 2■ of the second car blinks in accordance with the opening and closing of the intermittent relay contact 14.

Incidentally, since the upstream call assignment relay contact 2Gb of the second machine is open, the upstream call registration relay 2D is not deenergized.

When Unit 2 stops on the second floor, the door opens and after a certain period of time, the door begins to close.

Here, when two people press the up call button on the second floor, the door of Unit 2 flips over and reopens, and after a certain period of time, the door begins to close again.

When the door is completely closed, the stop command relay contact 13d opens,
Since the stop detection relay 2J is deenergized and the contact 2Ja is opened, the arrival forecast light 2■ of the second car is turned off.

Further, since the contact point 2Jb-2 is closed, all the up call indicator lights 2E on the second floor are lit.

Then, Unit 2 departs for the next call.

Next, when Unit 1 arrives at the second floor, the up call assignment relay contact 2Gb is still closed, so (G)-2Da-
2D-2F a-2Gb-11a -13a-← Due to the circuit, the up call registration relay 2D is deenergized, and the contact 2D
b is opened, and all the up call indicator lights -2E on the second floor are turned off.

Also, since the up call has been canceled, the up call assignment relay contact 2Gb.

2Gc is open.

Turning off the arrival warning light 2J of Unit 1, operating the door, etc. are the same as in Unit 2.

Furthermore, even after the door is closed, the second floor up call indicator light 2g will no longer be lit.

In this way, when the second car arrives at the second floor before the first car, the upbound call at the landing is not canceled, and the upbound call indicator light 2
Only E goes out, and when No. 2 departs, the up call indicator light 2 turns on.
Turn on the E light again to let the waiting customers know that car number 1 in the assigned car will arrive soon.

In addition, although each of the above-mentioned embodiments has been described with respect to calls going up from the hall, it is clear that the same applies to calls going down.

As explained above, in this invention, when there is a car that arrives at the floor before the car assigned to the hall call, the hall call indicator light for that floor is turned off, so the hall call button is pressed. When operated, it is possible to notify waiting customers that the door of the first-arriving car can be reopened.

Additionally, when the first car departs, the hall call indicator light is turned on again, so the call registration is maintained.
It is possible to reconfirm to waiting customers that the assigned car will soon arrive at that floor.
