JPH1121049A - Door controller of elevator - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a door controller of an elevator, not to remain in the opening extending time specification even if a passenger used an opening extending button, and able to prevent the calling time of a car from being extended. SOLUTION: A door controller of an elevator is provided with an opening button 1 for closing a door opening control circuit 16, a closing button 4 for closing a door closing control circuit 17, and an opening extending button 8 for closing the door opening control circuit so as to make the door opening extending time longer than the door opening time by the opening button 1. When the closing button 4 is operated, the door opening control circuit 16 is opened, while, when the opening extending button 8 is again operated during the door opening extending time, the door closing control circuit 17 is closed after the specified time passes.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator door control device.

[0002]

2. Description of the Related Art Conventionally, this type of door control device is configured so that, when the user wants to stop the door open extension specification after operating the open extension button, the user can operate the close button.

[0003]

In the above conventional example, when a passenger using the open extension button gets off from the car and there is no other passenger in the car, the following problems occur. is there.

(1) When a passenger using the open extension button gets off the car and operates the close button, the door is closed. Thereafter, when the operator operates the open button to get out of the car, the door starts closing as soon as the door is fully opened, so that the passenger is obstructed by the door, making it difficult for the passenger to get out of the car.

(2) Therefore, the passenger using the open extension button gets off the car without operating the close button, that is, with the extended extension time specification, so that passengers from other floors cannot use the button. Car call time becomes longer.

An object of the present invention is to provide an elevator door control device which can solve the above-mentioned problems.

[0007]

An object of the present invention is to provide an open button for closing a door open control circuit, a close button for closing a door close control circuit, and a door open extension time longer than the door open time by the open button. An opening extension button for closing the door opening control circuit, and an elevator door control device including at least, when the closing button is operated, the door opening control circuit is opened, When the opening extension button is operated again within the door opening extension time, this is achieved by closing the door closing control circuit after a lapse of a predetermined time.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS.

In FIG. 1, an elevator car 13 is shown.
Has an operation panel 14 and an openable / closable door 15.
The operation panel 14 has an open button 1, a close button 4, a destination floor registration button 5
And a floor extension button 8 are provided as shown in FIG.

[0010] The control circuit of the door control device is configured as shown in FIG. That is, to the open button 1, the open relay 2, the normally closed contact 5b of the closed relay 5, and the normally closed contact 9b of the first timer 7 are connected in series. A parallel circuit of a normally open contact 2a of the open relay 2 and a normally open contact 10a of the second timer 10 is connected to the door open control circuit 16 in series.

A close relay 5 is connected to the close button 4 in series. To the door closing control circuit 17, a parallel circuit of a normally open contact 5a of the close relay 5 and a normally open contact 7a of the first timer 7 is connected in series. The normally open contact 11a of the counting device 11 is connected to the first timer 7 in series.

The open extension button 8 includes a normally closed contact 5 of the closed relay 5.
b, the normally closed contact 11b of the counting device 11, and the open extension relay 9 are connected in series. In the second timer 10,
The normally open contact 9a of the open extension relay 9 and the normally closed contact 11b of the counting device 11 are connected in series. The normally open contact 9a of the open extension relay 9 is connected to the counting device 11 in series. The display device 12 has a normally open contact 9 of the open extension relay 9.
a are connected in series.

The counting device 11 calculates the number of times the open extension button 8 is operated, and closes the normally open contact 11a and opens the normally closed contact 11b when the open extension button 8 is operated again. Is configured. The display device 12 is configured to notify that the extension is being extended.

With the above configuration, the passenger who wants the extension time operates the extension button 8 on the operation panel 14 of the car 13. Then, since the open extension relay 9 is energized to close the normally open contact 9a and open the normally closed contact 9b, the open relay 2 is turned off, the normally open contact 2a is opened, and the second timer 1
0 operates to close the door open control circuit 16 by the normally open contact 10a. Therefore, after the elapse of the extension time set by the second timer 10, the door opening control circuit 16 is opened.

Next, when the open extension button 8 is operated again, the operation circuit is counted by the counting device 8, and when the open extension button 8 is counted twice, the normally open contact 11a is closed and the normally closed contact is closed. Since the contact 11b is opened, the open extension relay 9 and the second timer 10 are opened, and the first timer 7 is closed. Therefore, the door closing control circuit 17 is closed after the time set by the first timer 7 has elapsed.

As described above, by operating the extension button 8 again, it is possible to safely go out of the car 13 and, after the passenger has left the car 13, the extension extension time specification is automatically made. Is released, and then the car 13
The passenger using the car 13 can use the car 13 with a normal opening time specification.

[0017]

As described above, when a passenger using the open extension button gets off the car, the elevator extension door can be released only by operating the open extension button again. A control unit is obtained.
