Description

Description: TECHNICAL FIELD The present invention relates to an elevator door control device capable of improving the operating efficiency of an elevator.

[Related Art] In recent years, construction of high-rise buildings has progressed, and elevators installed in such buildings are required to have better service (operating efficiency). Conventionally, a method has been adopted in which a door is kept open for a set time of a timer unless a door close button provided on an operation panel in a car is generally pressed. With this method, if there is a passenger in the car, the remaining passenger presses the door close button as soon as the passenger gets on and off, so that the door can be closed and the call on the other floor can be answered promptly. After all the passengers get off in response to the last car call, the door close button cannot be pressed because there are no passengers. Therefore, in this case, since the door is kept open for a certain period of time, there is a problem that it is not possible to respond quickly to calls on other floors.

Therefore, as one means for solving this problem, for example, an elevator operating device disclosed in JP-A-52-106545 has been proposed.

[Problems to be solved by the invention]

By the way, when you arrive at the requested floor and the door opens, most passengers get off before the set time elapses,
When there is no traffic, there are only a few passengers and they get off before the door is fully opened. When the number of passengers who get off is large, or when it takes time to get off, the door safety and the opening button are operated to prevent the door from closing. According to the above-described conventional technology, when there are a plurality of car calls, the passenger must operate the close button to close the door in order to improve the driving efficiency for each car call. There is annoying passengers.

Therefore, the present invention has been made in view of the above-mentioned circumstances, and its purpose is to arrive at a car call only without hindering getting off, and to operate a passenger's closing button operation. It is an object of the present invention to provide an elevator door control device capable of improving the operation efficiency of an elevator by eliminating the trouble of the elevator.

[Means for solving the problem]

In order to achieve the above object, the present invention provides a door closing command means for issuing a door closing command simultaneously with completion of door opening when landing with a car call only, a door safety function for stopping a closing door and giving a reversal command, and When one of the open buttons is operated, a door closing delay means for delaying the door closing operation of the door for a predetermined time is provided.

[Action]

According to the present invention constructed as described above, if the vehicle arrives only by car call and the passenger does not operate the door safety or the open button, the door is closed immediately after the door is opened, and the elevator can respond to the call on the other floor. As described above, when a plurality of car calls are registered, it is possible to eliminate annoying a passenger to operate a close button for prompting a door to be closed one by one, and
By operating the door safety or the open button, the door closing operation can be delayed for a predetermined time, so that it is possible to safely get on and off the vehicle, and it is possible to greatly improve the unnecessary decrease in the operating efficiency of the elevator.

〔Example〕

 An embodiment will be described with reference to FIG.

P and N are power supplies, A is a relay for door closing command (door closing command means), A ₁ is a contact of the relay, TA is a timer for door closing delay command (door closing delay means), TA ₁ is a contact of the timer ,
C is a landing call arrival detection relay, C ₁ is a relay contact, D is a door closing delay detection relay, D ₁ is a relay contact, SS is a door safety device contact, OB is an elevator door opening button, CB Is an elevator door closing button, OLS ₁ and OLS ₂ are door opening completion contacts, 1 is a car call arrival detection circuit, and 2 is a hall call arrival detection circuit. In the above configuration, the door closing delay command timer (TA) and the car call detection circuit (1)
Since the hall call detection circuit (2) is a known circuit, its outline is shown.

If the elevator arrives at the destination floor due to a car call and there is no landing call at the destination floor, the car call arrival detection circuit (1) closes, and upon completion of the door opening, _{P-C 1 -1-OLS 1} -A-N circuit is configured, door close command relay a is turned ON, as soon as the door is cut open, the door begins closing. At this time, when the door safety device or the elevator open button is operated, the P-SS-OB-BN circuit is disconnected, and the door-closed reversal detection relay B is turned off. This closes the contacts of Yotsute B ₁ is constituted the circuit of P-B ₁ -D-N, the door delay detection relay D is turned ON. Yotsute that door delay detection relay D is turns ON, the circuit is formed of P-D ₂ circuit -C-N and _{P-D 2 -OLS 2 -TA-} N. Thus, the landing call arrival detection relay C is turned ON and the door closing delay command timer TA starts counting. P-C ₁ -1-OLS ₁ open hall call arrival detection relay C is is turned ON C ₁ -A-
The circuit of N is cut off and the door close command relay A is turned off.
OFF door close command relay A is Then, A ₁ is closed and P-D ₁ -A
The circuit of ₁ -DN forms a self-holding circuit of the relay D for detecting a door delay. Door closing delay command timer TA
But completes the counting, when the timer contact TA ₁ is closed, the circuit of the P-TA ₁ -A-N are configured and door close command relay A is, minute counted by TA timer and with a timed
Turn ON.

Next, a case where there is a hall call will be described. When the elevator arrives at the floor with the hall call, the hall call arrival detection circuit (2) closes and when the door opening is completed, P
The circuit of -2-OLS ₂ -TA-N is configured, and the door delay command timer TA starts counting. On the other hand, at the same time, the circuit of P-2-CN is configured, and the landing call arrival detection relay C is turned ON. Thus, P-C ₁ -1 open C ₁
-OLS ₁ -AN circuit is disconnected and door close command relay A
Cannot be turned ON. When the door closing delay command timer TA completes counting, the timer TA completes counting, and the timer TA ₁ closes, a circuit of P-TA ₁ -AN is configured, and the door closing command relay A Turns ON. When the elevator door close button is pressed, a circuit of P-CB-AN is formed, and the door-close command relay A can be arbitrarily turned on.

In the present embodiment, as described above, if the vehicle arrives only by car call and the passenger does not operate the door safety or the opening button, the door is closed immediately after the door opening is completed, and the elevator is called on another floor. If more than one car call is registered, the passenger can cancel the operation of the close button that prompts the door to be closed, and can operate the door safety or open button. Further, since the door closing operation is delayed for a predetermined time, complete and efficient door control of the elevator can be performed.

[Effects of the Invention] As described above, according to the present invention, when landing with only a car call, a door closing command is issued at the same time as the door opening is completed, and one of the door safety and the open button is operated. The door closing operation of the opened door is delayed for a predetermined time, so when landing with only a car call, if the passenger does not operate anything, the door is closed as soon as the door is opened, so it remains in the car. Then, the trouble of having to operate the door close button for passengers heading to other floors can be eliminated and the operation efficiency of the elevator can be improved, and when it takes time to get off, the door safety and open button By operating either one, passenger safety can be ensured without hindering the getting-off operation.
