Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator door controller, and more particularly to an elevator door controller having a plurality of cars installed therein.

[0002]

2. Description of the Related Art Conventionally, when a plurality of elevator cars (especially four cars or more) are installed, two or more hall call buttons are provided in a hall, and which of these hall call buttons should be operated. Also, a hall call common to each car is registered and the car can be called. However, when the number of cars is large (more than 6 cars) or the distance between the hall call button and the car is long depending on the number of cars, when the car door far from the operated hall call button opens, the normal door opening Passengers have to hurry to board as time is short.

For this reason, when the hall call button located at a position far from the position of the car waiting for door closing is operated as in JP-A-55-31722, the time for opening the door of the car is set. The passengers who operate the hall call button can be given a sufficient boarding time even if the car door at a distant position is opened, by making it longer than usual or delaying the door opening operation start time by a certain period of time. It is a device that can be used without the user.

[0004]

In the prior art described above, passengers can get in without hurry when operating a landing call button at a position far from the car waiting to be closed, but once the baggage is placed on the floor. When you have to operate the hall call button,
Even when a nearby hall call button was operated, if it took time to get on the car, it was sometimes impossible to get on the car.

SUMMARY OF THE INVENTION An object of the present invention is to provide an elevator door control device that can easily get in even if it takes time to operate a hall call button and get into a car.

[0006]

In order to achieve the above object, the present invention provides a plurality of cars managed by a plurality of hall call buttons, and a car that responds to the hall call buttons issues a door open command. The door is opened by the operation of the device, the closing button provided in the car is pressed, and the door is closed by the door close command device which operates after a predetermined time period set in the time device started by the operation of the door open command device. In the elevator door control device configured as described above, when the door is open and the door close command device is inoperative, the time measurement of the time limit device is performed by pressing at least one hall call button of the plurality of hall call buttons. It is equipped with a restart device for recounting.

[0007]

With this configuration, when any one of the landing call buttons is pressed before the door is opened and the door closing command is output, the restarting device is actuated to output the door closing command. The measurement is re-counted and the door opening time limit is re-extended.

As described above, the door opening time limit can be re-extended by pressing the hall call button before the door opening command is output.
Even when the car door at a position far from the pressed hall call button is opened, or when it takes time to get in, it is possible to get in without haste.

[0009]

An embodiment of the present invention will be described below with reference to the drawings.

In the figure, 1A to 1D are hall doors at the lowest floors of Units 1 to 4, respectively, and 2A and 2B are first floor hall call buttons which are shared by Units 1 to 4. This hall call button 2A
Is close to Group A of Units 1 and 2, and far away to Group B of Units 3 and 4. Further, the first floor hall rise call button 2B is arranged near the B group and far from the A group.

Further, between the power source P and N, the contact point 2Aa of the first floor hall rising call button 2A and one of the cars of Nos. 1 to 4 are connected.
A normally-closed contact 1Fb of a first-arrival relay (not shown) that is activated when the platform arrives at the first floor, and a first-floor landing rise call registration relay 3 having a normally-open contact 3a are connected in series, and a contact 2Aa,
The contact point 2Ba of the first floor hall rising call button 2B which is another common landing call button of the first floor hall and the normally open contact point 3a are connected in parallel.

Further, between the connection point of the normally open contact 3a and the normally closed contact 1Fb and the power source N, one of the normally open contact 1Fa of the arrival relay (not shown) and the landing doors 1A to 1D of Units 1 to 4 are connected. A normally open contact 4a1 of a first-floor door opening relay (not shown) that is energized when open, a normally-closed contact 11b of a door opening / closing command relay 11, which will be described later, and a first-floor ascending door open extension relay having a normally-closed contact 5b. 5 are connected in series.

Similarly, for an ascending call to the Nth floor, the contact NAa of the Nth floor ascending call button (not shown) and the normally closed contact NF of the Nth arrival relay (not shown) are similarly provided between the power sources P and N.
b and an Nth floor ascending call registration relay N having a normally open contact Na are connected in series, and a contact Na of an Nth floor ascending call button (not shown) which is another ascending call button at the Nth floor hall is connected to the contact NAa.
Ba and the normally open contact Na are connected in parallel.

Also, between the connection point of the normally open contact Na and the normally open contact NFb and the power source N, the normally open contact NFa of the N-level arrival relay (not shown) and any of Units 1 to 4 open the door on the Nth floor. A normally open contact 4Na of an N-floor door opening relay (not shown) that is energized during operation, and a normally-closed contact 6Nb of an N-floor door opening / closing command relay that gives a door closing command when energizing an elevator stopped on the Nth floor. , N-floor door extension extension relay 7N is connected in series.

Further, between the power sources P and N, a normally open contact 4a2 of a first floor door opening relay (not shown), a normally closed contact 5b, and a normally closed contact 8a of a first floor lowering door opening extension relay (not shown).
A timer T1 having a contact T1a that is closed after a predetermined time, for example, 3 seconds when energized, is connected in series.

Similarly, between the power sources P and N, there is a safety switch 9b attached to the door 1A of the first car, and a contact 10a of a door closing button (not shown) arranged on the operation panel in the car of the first car. The door opening / closing command relay 11 having the normally closed contact 11b is connected in series, and the contact T1a is connected in parallel to the contact 10.

The circuit for the ascending call of the hall has such a circuit configuration, and the same applies for the descending call, so the description thereof will be omitted.

Further, the door opening / closing command relay 11 is related to the opening / closing command of the door 1A of the first machine, and the same applies to the doors 1B to 1D of the other machines, so the description thereof will be omitted.

First, when the passenger presses the first floor hall call button 2B and the elevator No. 1 responds, P-2Ba
-1Fb-3-N circuit is formed, the first-floor hall rising call registration relay 3 is activated, and the first-floor hall rising call registration relay 3 is self-holding in the circuit of P-3a-1Fb-3-N. .

Next, when the No. 1 elevator arrives at the first floor, a not-shown first-floor arrival relay is energized, and the normally-closed contact 1F.
Since b is opened, the circuit of P-3a-1Fb-3-N is opened, and the first floor hall rising call registration relay 3 is deactivated.

Here, since the door 1A is opened, the door 1 is not shown.
The floor door open relay is energized, the normally open contacts 4a1, 4a2 are opened, the circuit of P-4a2-5b-8b-T1-N is formed, the timer T1 is energized, and the contact T1 is reached after 3 seconds.
a is closed, P-9b-10b-T1a-11-
The N circuit is formed and the door opening / closing command relay 11 is energized, so that the door 1A starts to close.

However, if the passenger does not notice the arrival of the elevator of the first car and decides that the door 1A will be closed by the time the passenger gets into the first car, he / she presses the first floor ascending call button 2B again, and then P-2Ba-1Fa. -4a1-11b-5-N circuit is formed, and the door open extension relay 5 is energized when the first floor rises,
Since the circuit of P-4a2-5b-8b-T1-N is opened and the timer T1 is deactivated, the time count is reset,
Again, it starts measuring 3 seconds which is the time limit of the timer T1.

Thus, when the door 1A is open, 1
By pressing the floor hall rise call buttons 2A, 2B, the opening time of the door 1A is re-extended, so that passengers can get on the car without haste.

[0024]

Since the door opening time period can be re-extended by pressing the hall call button before the door closing command is output, even if the car door at a position far from the pushed hall call button is opened, Even if it takes a long time to get in, it is possible to get in without rushing.
