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, and more particularly to an elevator door control device for extending the opening time of an elevator door by operating a hall call button.

[0002]

2. Description of the Related Art In general elevators for transporting passengers,
The hall call button or the car call button in the car is operated,
When the car arrives at the floor corresponding to the operation, the opening / closing means is activated to open the elevator door, and after a certain time (for example, 5 seconds), the elevator door is closed.
In this elevator for transporting passengers, even in a time zone where there are many passengers getting on and off at the landing, in many cases it is possible for the passengers to get on and off within the fixed time, and if it is not possible to get on and off within the fixed time, This can be dealt with sufficiently by operating the open button provided in the car.

However, in an elevator for carrying luggage or an elevator that also serves as passenger baggage, it may take time to carry in and carry out luggage. Therefore, an opening extension button is provided in the car and the car stops at the hall. When the open / extend button is operated later, the elevator door is opened for a predetermined time (for example, 3 minutes). However, when carrying luggage into the car, it is complicated to get in the car after the car arrives at the hall, operate the open / extend button, and get back to the hall to carry the luggage into the car. The burden on workers is heavy. Therefore, there has been proposed an elevator door control device in which an elevator door is opened for a predetermined time (for example, 3 minutes) when a worker operates the hall call button again after the car arrives at the hall.

[0004]

However, in the proposed elevator door control device, when a forklift is used for loading and unloading a car, a worker gets off the forklift and calls the hall. After operating the button and operating the hall call button again after the car arrives at the relevant floor, the operator returns to the forklift to carry in / out the luggage. For this reason, the operation of the hall call button is complicated, and even if the car arrives at the floor and the elevator door is opened, it is not possible to carry in / out the luggage immediately, and the working time is long. As a result, the operating efficiency of the elevator decreases.

The present invention has been made in view of the current state of the elevator door control device of this type as described above.
It is an object of the present invention to provide an elevator door control device that can be easily operated without imposing a burden on a worker who loads / unloads luggage into / from a car and can efficiently carry in / out luggage.

[0006]

[Means for Solving the Problems] The purpose is to operate a landing call button or a car call button in a car, and when the car arrives at a floor corresponding to the operation, the opening / closing means is activated. In an elevator door control device in which an elevator door opens on a floor and the elevator door closes after a certain period of time, storage means for storing an extension operation in which the hall call button is operated a plurality of times within a predetermined time, and this storage means This is achieved by providing an extension means that operates by the memory of the extension operation and extends the opening time of the elevator door on the floor where the extension operation is performed.

[0007]

With this construction, when the hall call button is operated a plurality of times by a plurality of operations within a predetermined time, the storage means stores the extension operation. Then, by the storage of the storage means, the extension operation is performed to extend the opening time of the elevator door by a single simple extension operation at the hall.

The counters CNU, CND and the time relays CD, CD form the main part of the storage means of the present invention, and the opening extension auxiliary relays CUM, CDM and the opening extension command relay OE form the main parts of the extension means of the present invention. There is.

Next, the operation of the embodiment having such a configuration will be described.
For example, a case will be described in which the elevator hall button UB is operated in the hall on the third floor to raise the car that is stopped at the hall on the first floor. First, in the case of carrying a normal passenger, when the passenger pushes down the ascending hall button UB once in the hall, the contact UBa is closed and the auxiliary relay UX is energized, and the normally open contact UXa1 is opened. Close. When the normally open contact UXa1 is closed, the lift relay U is energized, and the normally closed contact is closed until the car reaches the third floor.
Self-held by 1. In this way, the rising relay U
As the car is urged, the car starts ascending operation, arrives at the third floor hall, the normally closed contact UPb is opened, and the ascending relay is deactivated. Then, the elevator door is opened by the opening / closing means, and when it is in a completely opened state, the relay (not shown) is deenergized, the normally closed contact OLSb is closed, and DC power is supplied to the timer TA, so the timer TA counts. After 5 seconds, the normally open contact TAa is closed.

In this case, since the normally open contact UXa3 is closed only once within a predetermined time, the counter CNT does not operate and the time relay CU does not energize. Therefore, the opening extension auxiliary relay CUM is not energized, and the opening extension command relay OE is not energized, so the normally closed contact OEb is in the closed state, and the elevator door is not closed, so the normally closed contact CLSb.
Is in a closed state. Therefore, when the timer TA starts counting and the normally open contact TAa is closed after 5 seconds, the door closing command relay CL is energized to start closing the elevator door.

Next, when an operator carrying in / out the luggage to / from the car by using the forklift gets off the forklift and pushes the ascending hall button UB twice within 2 seconds, the same operation is performed. The contact UBa is closed, the auxiliary relay UX is energized, and the normally open contact UXa1 is closed. When the normally open contact UZa1 is closed, the ascending relay U is biased and self-held by the normally open contact Ua1. In this way, the elevator relay U is energized, so that the car starts ascending operation and arrives at the third floor hall. In this case, the normally open contact UXa3
Since it is closed twice within 2 seconds, the counter CNU operates to close the normally open contact CNUa, and the timely CU is energized to close the normally open contact CUa to perform the memory operation.

When the car arrives at the third floor hall, the normally-open contact La is closed, so that the extension auxiliary relay C is opened.
The UM is energized to close the normally open contact CUMa. At this time, since the normally closed contact TEb is closed, when the normally open contact CUMa is closed, the open extension command relay OE is energized, and the normally open contact OEa1 is self-held and the normally closed contact CUMb is opened. The time relay CU deactivates after 1 second. When the car arrives at the third floor hall and the elevator door is completely opened, the normally closed contact OLSb is closed and the normally open contact OEa2 is closed by the bias of the open / extend commanding relay OE. The timer TE operates and starts counting, and at the same time, the timer T
A also operates and starts counting.

In this state, the timer TA counts up after 5 seconds and the normally open contact TAa is closed, but the normally closed contact OEb is opened by the bias of the open extension command relay OE, so the door is closed. The command relay CL is not energized. After 3 minutes, the timer TE counts up and the normally closed contact TEb is opened, and the open extension command relay OE is deenergized. Therefore, the normally closed contact OEb is closed and the door close command relay CL is energized. And the elevator doors begin to close.

In the embodiment, the ascent button UB is 1
After 2 seconds have passed since the wheel was operated, the landing button ub for climbing is pressed again.
Even if operated one time, the one-shot timer TSU does not operate, the normally open contact TSUa is open, and the counter CNU
Does not operate and the opening extension operation is not performed. In this case, if the ascending hall button UB is operated twice within 2 seconds thereafter, the opening extension operation is naturally performed.

As described above, in the embodiment, the ascending hall button UB
If the button is operated twice within 2 seconds, the opening time of the elevator door of the car arriving at the landing will be extended to 3 minutes, so the worker will ride the forklift after operating the lift landing button UB and It is possible to wait for arrival and carry on the loading and unloading work of the luggage immediately after the arrival of the car, and it is possible to carry out the loading and unloading work efficiently without lowering the operation efficiency of the elevator.

In the embodiment, the case where the car is operated to move up has been described, but the same can be applied to the case where the car is operated to move down. Further, in the embodiment, the hall button B is set to 2
If operated twice within a second, the elevator door opening time will be 3
However, the present invention is not limited to the embodiment, and the operating condition of the hall button B and the opening time of the elevator door are set to optimum values according to the usage state. be able to.
