Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to an elevator door opening/closing control device. [Technical Background of the Invention] Conventionally, when a hall call is registered, a service elevator is assigned. When the passenger receives a car call, the elevator stops, opens the door, and guides the passenger.If this passenger gets on elevator C2 and registers a car call, the elevator will automatically take them to that car call floor. - When the elevator arrives, the elevator door is opened and the passengers are let off. In this case, the elevator door opening time is usually 2~
3 seconds, and once this time has elapsed, the door will automatically start closing.

In high-end elevators, it takes about 3 seconds to respond to a hall call, and about 2 seconds to respond only to a car call.
2. The type of call answered C; therefore, the door opening time may be differentiated.O [Problems in the background art] However, as shown in Fig. 1, a passenger l receives a hall call from the hall call registration button 2g Once registered, the service elevator responds by flashing the arrival forecast light J to guide passengers (some cars do not have an arrival forecast light) and then exit to door 4 of the service elevator.
If the door 4 is opened or the passenger is waiting or moving around the boarding area, the door 4 will start closing after 22 to 3 seconds, so the passenger has to get on the train quickly. To feel danger from a door that is closing I: Become. Additionally, in this case, the elevator door 4C is equipped with a safety measure to eliminate the anxiety of the passengers, even though the door 4 seems to reopen when it hits someone's body. This is not possible ◎Moreover, (2) Especially in group control elevators, etc., the elevator hall is large and the travel distance to the service elevator is long, so if the door of a stopped elevator opens from the floor where the call was registered to 2 ( :In many cases, the elevator starts closing its doors while a passenger is moving from one boarding area to another. in,
The purpose of this is to eliminate the danger and frustration caused by door closing operations for passengers, eliminating the need for passengers to get on and off the elevator without compromising its efficient operation.

Make getting on and off the elevator smooth and easy! j-bi lecture.

It is an object of the present invention to provide an elevator door opening/closing control device that can achieve the above.

[Summary of the invention]

In order to achieve the above object, in the present invention, when an elevator receives a hall call (when a car call for that elevator has not yet been registered when the elevator answers), the door opening time due to a normal hall call or car call response is The door is kept open for a long time to allow passengers to get on and off the car smoothly, and the door closes when a car call is registered.

[Embodiments of the invention]

An embodiment of the present invention will be described below. First, Figure 2 shows a passenger pressing the call registration button in an elevator car to which the present invention is applied, as seen from inside the car. This is a diagram. In Figure G2, 5 is a call registration button, 6 is a door open push button, and 2 is a door close push button.The third figure shows an example of the configuration of a car call non-detection device according to the present invention C2. The original car call registration circuit and call detection circuit are both shown in the figure.

19 is a door open command time-limited relay with a longer off-delay (10 seconds & [) than usual, 19 m.

198m is the a contact point, which is configured as shown in the notice.Next, when a customer who is about to use the elevator with this configuration C2 presses the hall call registration button 2 on the A floor, the fourth
The two A contacts of the hall call button in Figure C2 close, hitting the gate of thyristor 74A, causing the thyristor to σN.
Then, current flows from the thyristor 14k through the resistor J7A, and the hall call is registered. Then, for this hall call≦2, an elevator is assigned, decelerates to that hall, stops, and opens the door.Also, at the same time as decelerating to the registered hall (second hall call response detection relay 16 is energized) When the elevator connects to the door zone, the 51st!!!11 contact 21m closes and the door open command time limit relay 18 is energized.

The contacts 18 & of the time limit relay 18 close, and the door open command relay 20 is energized to start the door opening operation. In this case, conventionally, the setting time of the relay 18 is about 3 degrees, and the door opening command relay 20 is energized to start the door opening operation. The door started to close after the 3rd episode as in cause 6 A.Therefore, if the door release button was pressed inside the car (if it were done, passengers waiting at the landing would be able to board the car smoothly).

If there is a passenger in the car, the door closing operation will be started.In this regard, in the present invention, as shown in FIG. Door open command time limit (about 10 seconds), Ray 1
Because 9 is set.

If a car call is not registered yet, contact lOb is closed, so relay 18 and relay 19 are also energized, and door open command relay 20 is activated for a longer time than usual at 3M.
Then, the door waits in the open state (Fig. 6B).
When a predetermined period of time (approximately 10 seconds) has elapsed, the time limit relay 19 is deenergized and the door open command relay 20 is turned off to begin closing the door.

On the other hand, when the time limit relays 18 and 19 are energized once, the contacts 18aBm19m are closed and held. When the door close button is pressed, the contacts 2b and yb are opened and the holding is released. Furthermore, when a passenger enters the car and registers a car call, the contact lQb of the door open command time-limited relay 19 opens, so the time-limited relay 19 is reset, and the door open command relay 20 is also deenergized and the door begins to close.
In the figure, when the car call registration button 5 on the A floor is pressed in the car, the thyristor 8A operates, and the ti current flows from this to the resistor 13 to register the car call on the A floor. A current flows through J\, and the car call non-detection relay 10 is energized. In other words, when one or more car calls are registered, relay IO is energized @ll is car call LC> This is a valley detection relay, and when the registered car call floor i elevator arrives, the floor selector movable piece FS is activated.
energized via IV+, and when the door zone is reached, relay 18 of FIG. 5 is energized and the door opens.

The above-mentioned door opening/closing time chart is shown in Fig. 6 (◎ 1 indicates that the door opening signal is output.

0 indicates nothing. A shows the door opening/closing according to the conventional car call or hall call response C2. B shows the present invention C:
This shows a case where the car call is not registered even if the passenger responds to the hall call 52. In this case, the door starts closing in about 10 seconds. C is.

If the car call is answered within 10 seconds after 3 seconds after the door is opened, D indicates the case where the car call is registered within 3 seconds after the door opener. When a customer registers a hall call and the service elevator opens the door, if no car call has been registered yet, the service elevator will wait with the door open, and close the door when the customer gets on board and registers a car call. Since the start, customers.

You can ride the C2 smoothly without feeling any danger or anxiety, even if there are no passengers.

The door will be closed after a predetermined time limit (10 seconds!”Aa), so
There will be no hiccups in elevator operation efficiency. ・If a car with a car call already registered speeds up at the hall call and opens the door, if the person inside the car is kind enough to do so, press the door open button and open the door. There is no problem even if one of the devices does not work.

In this way, when a hall call is registered, a service elevator is assigned, and the elevator door opening/closing control device responds to hall call C2, stops, and opens the door for a certain period of time (3 seconds). a hall call response detection circuit that detects that the elevator has stopped and the door 4 has been opened; a car call non-detection device that detects whether a car call is registered; and the hall call response detection circuit that operates. In addition, on the condition that the above-mentioned car call non-detection device≦2 and there is no call detection, 1.Normal hall call or car call response 5.2. Door opening time (
The elevator door opening/closing control device includes a device that outputs a door opening command for a predetermined time (10 seconds) that is longer than 3 seconds).

When the customer registers a car call and the service elevator opens the door, the customer does not start closing the door for a sufficient period of time until the customer enters the car and registers the car call. You can board the train without feeling any danger from the closing of the door. Also, there is no need to re-register for a boarding call if a passenger waiting 52 holes missed the train because the door was closed. In addition, in the case of group-controlled elevators that used to have temporary platforms, the same elevator was not always assigned as a service elevator, so even if the elevator is re-registered, if the door has been closed, other hall calls will be assigned to that elevator. If it is assigned, it will depart and the longevity will be ζ2.

Furthermore, in the case of a group-controlled elevator in a landing area, C- has a long distance to travel through the landing area, so the present invention is effective.

゛In addition, in the above embodiment, the door opening time due to call response C2 and the door opening time due to hall 1 call response -5 are set to be the same time (
3 seconds), but 1. For example, in the case of a car call response, 2.
It is clear that the present invention can be easily applied to cases where door opening times are originally different, such as 3 seconds in the case of answering a hall call in 1 second.

〔Effect of the invention〕

As explained above, according to the present invention, it is possible to smoothly board and exit the elevator by reducing the sense of fear and anxiety of the guests by closing the door without impairing the efficient movement of the elevator. It is possible to provide an extremely reliable elevator door opening/closing control device that can provide the same services as above.
