Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an elevator door control device, and more particularly to an operating device for extending the opening time of an elevator door.

[Conventional technology]

In general shared elevators, a method is adopted in which the elevator doors automatically close in 3 to 5 seconds from the viewpoint of operational efficiency. In addition, elevators for sleeping beds and receiving goods used in hospitals and department stores are equipped with a door opening time extension button to allow time for loading and unloading beds and parcels. Extending time.

Conventionally, when this door opening time extension button is pressed, the button lights up and the time that the door is open is extended, and after a certain period of time (approximately 3 minutes) the lamp turns off and the button is forcibly pressed while sounding a buzzer. The structure was such that the door would close at any time.

Note that this type of door control device is manufactured by the Japanese Patent Publication Publication No. 56-15.
There was an elevator door control device mentioned in Publication No. 388.

[Problem that the invention seeks to solve]

The conventional door opening time extension button is generally placed in an exposed state on the operation panel, and, as mentioned above, is activated by pressing the button.

In elevators installed in places that can be used by general users, the extension button can be operated by general users.
In particular, if a child or other child plays a trick and leaves the door open extension operation unreleased, the elevator will continue to operate on other floors until the door opening time limit expires on that floor and the door is opened. Even if a call is registered, the call cannot be answered, resulting in extremely poor operational efficiency and a disadvantage in that service to customers attempting to use the elevator on other floors is degraded.

The present invention has been made in view of the above-mentioned circumstances, and its purpose is to provide a simple service that only specific users can use in elevators installed in places where unspecified people can use. To provide an elevator door control device equipped with an inexpensive door opening extension device capable of extending the door opening time by operation.

[Means for solving problems]

In this invention, the rjF1 button has a structure that can be pushed or pulled, and each open button is provided with a switch that is activated only when the button is pushed or pulled. On the other hand, a timer is provided to extend the opening time from when the door is opened until it is closed.

In this invention, a circuit is provided for each switch to open a door that is to be closed when the open button is pressed, and to operate a timer when the open button is pulled.

[Effect]

In this way, the opening button in the present invention is structured so that it can switch in two directions: push and pull.

When the elevator door is closed, it is reversed or reopened by pushing the open button as in the past, and extending the door opening is done by pulling the open button. The opening button is provided to reverse a closed door or open a closed door, and there is a concept that the opening button achieves its function by being pushed.

Normally, general users do not have the concept of performing a pulling operation. Therefore, only specific users who know how to extend the opening by pulling the opening button can easily extend the opening, making it possible to extend the opening using the conventional method. It is now possible to prevent problems such as a drop in elevator operating efficiency due to mischievous operations by unspecified customers.

〔Example〕

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

FIG. 1 is a front view of the operation panel 1.

FIG. 2 is a longitudinal cross-sectional view of the open button 2 seen from the X-x direction. In the figure, the open button 2 is provided with a movable contact 7, which is connected to the main body case part 8 through the spring 3 in the center of the figure. It's settled. The main body case 8 is provided with a door opening contact 6 and an opening extension contact 5, and when the movable contact 7 operates, the contact and separation operations are performed. Further, an indicator lamp 4 is supported on the main body case 8, and the indicator lamp 4 lights up when the opening extension circuit is operated.

When the open button 2 is not in operation, the movable contact 7 and the door opening contact 6, which are integral with the open button 2, are in contact with each other and are supported by the spring 3.

Now, if the user presses the open button 2 with his finger, the movable contact 7 integrated with the pause button 2 moves in the direction A due to the pushing force and separates from the door opening contact 6, resulting in the door being in the open state. As long as the operation is continued, the movable contact 7 and the door opening contact 6 will not come into contact with each other, and the door opening state can be maintained. Also, open button 2
The opening button 2 is pressed by the elastic force of the spring 3 provided on the middle man.
The movable contact that moves in direction B and is integrated with the open button 2 comes into contact with the door opening contact 6 and becomes inactive.

Also, if the user pulls the open button 2 with his finger to extend the door opening, the movable contact 7 integrated with the open button 2
moves in direction B and comes into contact with the door opening contact 6 and the contact 5 for separating and extending the opening. At this time, the movable contact 7 is stopped by the stopper 9 attached to the middle part of the open button 2, and the open button 2 is stopped at the place where the movable contact 7 and the opening extension contact 5 come into contact, and at the same time, the movable contact 7 and the open button Due to contact with the extension contact 5, a conductive state is established, and the open extension circuit is brought into an operating state.

To confirm the operating status, the display lamp 4 lights up, and when you release your finger, the open button 2 moves in the direction A due to the elastic force of the spring 3, and the movable contact 7 leaves the opening extension contact 5 and returns to the door opening contact. 6 and becomes inactive.

Next, the operation of the door opening extension circuit will be explained using FIG.

First, the known elevator door opening/closing auxiliary relay MA and the door opening/closing operation will be briefly described. When door opening/closing auxiliary relay MA is turned on, its contact M A is turned on,
When the door closing completion switch C81 is on (that is, when the door closing is not completed), the p-cs knee M A a -
Thyristor SHI becomes conductive due to S Ht. Therefore,
The door motor M is driven in the door closing direction. Further, when the door opening/closing auxiliary relay MA is turned off, the thyristor SHz is made conductive by the P-OS x-M A 4 S Hx when the door opening is not completed. Therefore, door motor M
is driven in the door opening direction. On the other hand, after a predetermined period of time has elapsed after the normal elevator door is opened, the door is automatically closed. At the time, the contact ○s1, which turns on when the door is opened, turns on.
N forms a closed circuit, and the door closing command timer TA counts the elapsed time after the completion of door opening. When the door closing command timer TA counts for a predetermined period of time, the contact point TA
Turn on the door opening/closing auxiliary relay MA.

As a result, the door motor M is driven in the door closing direction in the same manner as described above.

Consider a case where the opening time extension button OBA is pressed while the door closing command timer TA is currently counting using the known circuit as described above.

This turns on the opening time extension auxiliary relay A.

By turning on this relay A, P -A z -T B
A 1-L-N circuit is constructed, and the opening time extension indicator lamp L lights up. Also, since the opening time extension relay B is turned on by P I'-z B-N, P -M A
It maintains itself by the closed circuit of 2Bl-B.

P-O8I B2 TA N circuit is disconnected,
Aborts normal door closing operation.

As soon as you release the button OBA for extending the opening time,
P -M A x B 1- A a -T B -
Since N is configured, the extension command timer TB starts counting.

When the extension command timer TB completes counting and its timer contact T B 1 closes, P -T B z-
BZ-N causes the opening time completion alarm buzzer to sound.

At the same time, P -M A 2- B s T B I
L-N is disconnected and the opening time extension indicator lamp L goes out. This notifies the user that the extension time has been completed.

Meanwhile, at the same time, the extension completion command timer TC loses its count for the first time due to P-T B2- T C-N. After a certain period of time, the timer contact T C1 closes,
Since the opening/closing auxiliary relay MA is turned on by P SS OB At-TCt MA-N, the door closing thyristor SH.l is turned on as described above, and the door is closed for the first time.

Also, P -M A z -B I A a T
Since the circuit B-N is disconnected, the extension command timer TB is turned off, and the circuit PTB2-BZN is
It is disconnected, the opening time completion alarm buzzer stops sounding, and
If you press the opening time extension button OBA again at any time during the opening time extension, the opening time extension auxiliary relay A will turn on at that point, which will disconnect the opening/closing auxiliary relay MA and prevent the door from opening. ,P-M A x B 1-
By disconnecting A s -T B -N, the extension command timer TB is turned off, so from that point on, the time is extended again and the count is reset for the first time. Also, if you want to close the door while counting the opening extension time, press the close door button CB, P-3S-OB-CB-MA-N will be configured, and the opening/closing auxiliary relay NA will turn on, so the door will close. Closed at this point.

According to one embodiment of the present invention, the door opening time extension operation as described in detail above is based on the concept that the function is achieved by pressing an open button that extends the door opening time. Usually, general users do not have the concept of pulling the button. Therefore, only certain users who know how to operate the opening extension by pulling the button can now easily extend the opening, unlike the conventional method. It is now possible to prevent problems such as a decline in elevator operating efficiency due to mischievous operations by unspecified customers.

〔Effect of the invention〕

According to the present invention, only a user who knows how to extend the opening of a door can extend the opening of the door with a simple operation. This no longer reduces the efficiency of elevator operation. Furthermore, it has become possible to prevent mischief at a lower cost than a method using a magnetic card or the like in which a special code or the like is stored.
