Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a door control device for restarting the door of a car that is stopped at the front stage using the front stage button.

In recent years, various group control elevators have been announced that use an allocation method to allocate a Hataba call to a car. This is a method of assigning the above-mentioned Hataba call.

In the group control elevator using the above-mentioned allocation method, a door reopening operation is also performed, and this operation will be specifically explained.

Currently, car number 1 is assigned to the upstream Hataba call on the 3rd floor, and in order to inform the Hataba that it has been assigned,
It is assumed that the arrival forecast light on the upper floor is on.

When the car of No. 2 operating in the up direction arrives with a car call on the 3rd floor, the car of No. 2 will notify the landing by flashing the arrival forecast light of its arrival, and open the door. Try to get the passengers out of the car and close the door. At that time, 1
When the person who was holding the car in front of the No. 2 car noticed that the car in No. 2 had arrived and pressed the button for the third floor up platform, the car in the No. 2 car reopened its door according to the Hataba button signal. That person will be placed in the car of No. 2. but,
Car number 1, which was assigned to the 3rd floor upstream Hataba call, was 3rd floor.
In a system that stops at the first floor, it is more difficult for the second car to reopen the door and serve a person who has missed the second car than for the first car, which is assigned to the second car. Opening the gate further necessitates unnecessary movement of waiting customers.
The guiding time becomes longer and driving efficiency decreases. Also, future 1
This can also cause the cars in Units 1 and 2 to run in a stacked manner (multiple cars running close together, resulting in longer waiting times for passengers). However, if the door is not constantly reopened, it may take a long time for the next basket to arrive, which leaves customers dissatisfied. This invention solves the above-mentioned drawbacks, and eliminates the dead time of reopening the door by restricting the opening operation of the door using the Hataba button, resulting in good operational efficiency.
It is an object of the present invention to provide an elevator door control device which does not cause dissatisfaction to customers waiting in the parking lot.

An embodiment in which the present invention is applied to an elevator installed in a one-story building will be described below with reference to FIGS. 1 and 2.

In the diagram, 10 and 1 are DC power supplies, la to 9a are from the 1st floor, respectively.
Assigned up hall call relay contacts that close when a car is assigned to the 9th floor up Hata call, 2b to 10b are the assigned down hall call relay contacts for everyone from 2nd floor to 1, IA
~9A are assigned up call relays for the 1st to 9th floors, respectively;
IAa, lAb ~ 9Aa, 9Ab are the normally open contacts, 2B
~10B is the assigned down call relay of 1 tsubo cost on the 2nd floor, 2nd side, 2Bb ~ 10th string, 10Bb is its normally open contact,
lc to 9c are the call buttons for the 1st to 9th floors, 2D to 100 are the call buttons for the 2nd floor to 1 Kaga, and IE to 9E are the car position contacts for the 1st to 9th floors, 2F to 10F also has car position contacts from 2nd floor to 10th floor,
11 is a departure relay contact that is opened when issuing a departure command to the car, 12 is a door full-close relay contact that is opened when the door is fully closed, and 13 is an upstream relay contact that is closed when the car is serviced in the upstream direction. , 14 is a downward relay contact, 15 is a door full-open relay contact that opens when the door is fully opened, 16 is a door restart relay, and 16a is its normally closed contact.

The above circuit is shown only for the first car, but other cars have similar circuits.

Now, an example will be explained in which the car of No. 1, which is set for up-direction operation, arrives at the 1st floor by a car call on the 1st floor, and the car of No. 2 is assigned to the up-hata call of the 1st floor.

Even if the first car arrives on the first floor with the upward direction,
Since the floor assignment Qin bath call relay contact la is open, the assignment up call relay IA is not energized and contact l
Ab is open, so press the ``1st floor up Hataba call button''.
Even if c is pressed, the door-opening relay 16 is not energized and the door-opening operation does not occur.

At that time, since the assigned upstream call relay contact la on the 1st floor of Unit 2 is closed, the assigned upstream call relay IA on the 1st floor is energized by the circuit 111a-IA--.
By closing the contact IAa, it is self-retained via the contact 12. Contact lAb is also opened. In this state, when the second car arrives at the first floor for upward service,
The car position contact IE and the upstream relay contact 13 on the first floor of the No. 2 car are opened. Then, when Unit 2 is about to close the door, when the first floor ascending Habata call button lc is pressed, the circuit of 11lAb-lc-IE-13-16-- causes the door opening relay 16 of Unit 2 to close. is energized and self-retains by closing contact 16a. Then, the door is reopened according to an instruction from the door reopening relay 16. Thereafter, when the door is fully opened, the contact 15 is opened, the door reopening relay 16 is deenergized, and one door opening operation is completed. Next, when the door of the No. 2 machine starts to close, if the upstream Habata button lc is pressed again, the door will be reopened in the same way. After that, when a departure command is issued to Unit 2, departure relay contact 11 opens, and when the door is fully closed, contact 12 also opens, so the assigned upbound call relay IA on the 1st floor of Unit 2
is deactivated. After that, even if the upstream Qinba button lc is pressed, the door does not reopen. FIG. 3 shows another embodiment of the present invention. In contrast to FIGS. 1 and 2 in which only the cars assigned to the Hataba call are reopened, the door reopening operation is performed for the cars assigned to other cars. When a car arrives at an empty bath, the door will be reopened even if it has not been assigned.

Figure 3 shows only the upstream Hataba button lc on the first floor in Figure 2, and Figure 2 shows the normally closed contact IAc-2 of the upbound call relay IA for the car of No. 2, and the normally closed contact IAc-2 of the upbound call relay IA for cars No. 3 to No. 8. Similar contacts IAc-3 to IAc-8 of the cage are added.

Note that the part for machine No. 1 is indicated by "-1".
Now, when the first car arrives at the first floor with the up direction, the car position pupil contact IE-1 and the up direction relay contact 13-
1 is open.

At that time, if there is no other car assigned to the upstream Qinyu call on the first floor, all contacts IAc-2 to IAc-8 are closed. At that time, the upstream Hataba button lc on the 1st floor
When is pressed, (10) - (IAc-2) - (IAc-3
)−・・・・・・・・・(IAc-8)−(l c)−(I
The door reopening relay 16-1 is energized by the circuit E-1)-(13-1)-(16-1)-(1), and the No. 1 car can reopen the door. Although not shown, it goes without saying that the same circuit as the contact lAb-1 is added to the contacts 2Bb to 9Bb and 2Bb to 10Bb in Figure 2. A case has been described in which the door reopening operation is performed only for a car and a car that arrives with a car call at a Hata field where there is no assigned car.

In this case, even if there is no door-reopening operation, the customers waiting at Hataba will be satisfied because the next car to be serviced has already been reserved. If the car takes a long time to arrive, it will be more friendly to elevator users if the door is opened even if the car arrives with a car call.

As explained above, in this invention, when the car assigned to the Hataba call arrives, or the car arrives due to the car call being registered when the assigned car is not there, the door is opened by the Hataba button. By allowing the elevator to reopen, and preventing the door from reopening in other cases, the wasted time required to reopen the door is eliminated, making it possible to improve the operating efficiency of the elevator and making it easier for customers waiting in the elevator to use the elevator. It can be made easier.
