Description

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

[Conventional technology]

In a general shared elevator, 3! ! In order to improve efficiency, elevator doors automatically close in 3 to 5 seconds, but elevators for sleeping beds and receiving goods used in hospitals, department stores, etc. do not allow the loading and unloading of sleeping beds or parcels. In order to save time, a door opening time extension button is provided, and by pressing the button, the number of people opening the door can be extended. For example,
An elevator door control device as shown in Japanese Patent No. 388 is provided.

[Problem to be solved by the invention]

By the way, while the car is moving to the desired floor after loading cargo into the car, if a passenger answers the call for a landing on an intermediate floor and gets on the car, depending on the space inside the car, the cargo handler may move to the back of the car. Sometimes I have no choice but to go to When the car arrives at the floor desired by the cargo handler and the cargo is unloaded, especially when a cart is used, this is usually when the cart is carried into the car.

In order to make it easier for cargo handlers to carry out carts, they carry the carts in with the handle facing toward the depth of the car.

Therefore, I had to go to the operation panel, operate the opening extension button, and then return to the steering wheel position.
Because this action is a nuisance, I do not operate the opening extension button to extend the opening time of the door and carry out luggage, and because of the nuisance, I do not open the door to other passengers near the driver's panel. It is not possible to extend the opening time of the door by requesting the operation of the extension button, and the current situation is that cargo is carried out without extending the opening time of the door.

Therefore, the normal door closing time occurs during loading or unloading, and the door may close and collide with a truck or the like, resulting in damage to the door.

In addition, the door opening extension time is set to, for example, 3 minutes, so if the time for loading or unloading luggage exceeds the set time limit, it is necessary to operate the opening extension button again, but this is a cumbersome operation. Without.

The current situation is that cargo handling work is being carried out in a hurry.

Many of the causes of door damage are due to the reasons mentioned above.

Therefore, the present invention has been made in view of the above-mentioned actual situation regarding cargo handling, and its purpose is to eliminate the troubles of cargo handlers, to smoothly carry out the work of carrying out cargo, and to prevent damage to the door. An object of the present invention is to provide an elevator operating device that can eliminate the above factors.

[Means to solve the problem]

In order to achieve the above object, the present invention provides an elevator operation device having a door opening extension device that extends the opening time of a door when an opening extension button is operated, each time the door opening extension device is operated. .

A storage device that stores the time from the start of door opening extension until the release of the operation, and a time stored in the storage device when the door is opened at the floor where the first car call is answered after the release is performed. The configuration includes a control section that controls opening.

[Effect]

This is because the present invention has the above configuration.

During cargo handling operations, by operating the opening extension button when loading cargo, the system will automatically extend the opening for the time required to carry the cargo on arrival at the destination floor, reducing the inconvenience of cargo handling workers after they arrive at the destination floor. This can eliminate the cause of damage to the door when carrying out luggage.

12 is a relay for automatic opening extension command; 13 is a circuit that holds the automatic opening extension command for the door opening time period measured in 6; The present invention will be described in detail with the above configuration.

When attempting to transport cargo from the 1st floor to the Nth floor using the elevator, if it seems that it will take a long time to carry the cargo into the elevator, the cargo handling worker operates the opening extension button to set the door opening time limit. Extend. By this operation, the door opening extension command relay 4 is energized, and the normally open contact 4A causes the P-IB
-4A-2-N circuit is formed and a door opening command is issued. At the same time, normally open contact 4D of relay 4 for door opening extension command
The P-IC-4D-6-N circuit is formed, the door close command relay 1 is energized, and the door open time measurement counter is used to set the time until the circuit is opened by the normally closed contact IB and IC. At step 6, the door opening time limit is measured.

After the cargo has been brought in, the cargo handler will go to the car call button 24N on the N floor.
When operated, the car call registration relay 7N for the N floor is energized by the circuit P-24N-3NA-7N-N, and is held by the normally open contact 7NA. At the same time, the car call registration timer 8N is also activated. Then, only when the elevator reaches the destination floor is the normally closed contact 3NA of the car position detection device.

Although the car call registration relay 7N is deenergized, the normally open contact 8NA is held for a predetermined period of time by the car call registration timer, so the normally open contact 3NB of the car position detection device
A circuit NA-3NB-9N-N is formed, and the auxiliary relay 9N for detecting the arrival of the car call floor is energized. Therefore, a circuit of P-9NA-10-N is formed by the normally open contacts 9NA, and the car call floor arrival check relay 10 is energized. As a result, the circuit of P-1OA-5A-4-N is opened, but since the normally open contact 5A is held for a predetermined period of time by the auxiliary timer 5 of the relay for door opening extension command, the relay for detecting arrival of car call floor P-10B-5A due to the normally open contact 10B of
-11-N circuit energizes the automatic opening extension command auxiliary relay 11. With this normally open contact 11A, P-1
A circuit of 1A-13-12-N is formed, and by energizing the automatic open extension command relay 12, a circuit of P-IB-12B-2-N is formed by the normally open contact 12B, and the car call is activated. Only when you arrive at the registered floor will you be automatically extended.

In addition, the door opening time limit in the automatic opening extension state is determined by the automatic opening extension command relay holding circuit 13, which determines the time required for loading the luggage (
The automatic opening extension command relay 12 is held by the data of the door opening time limit measurement counter 6), but the circuit of P-IB-12B-2-N is opened by operating the door and door close buttons.

As a result, when carrying cargo into the elevator during cargo handling work, by operating the extension button, the extension button will be automatically extended when the destination floor is reached, so you will not have to operate the extension button when unloading. This eliminates the need for cargo handling, which eliminates the hassle for cargo handling workers, and also sets the one-open extension time to the time required to bring in the cargo, rather than the set value.
It is now possible to eliminate the cause of door damage when carrying out luggage.

〔Effect of the invention〕

As explained above, according to the present invention, in cargo handling work, by operating the extension button at the time of carrying in the cargo, the pawl is automatically extended in the open state for the time required to carry the cargo upon arrival at the destination floor; This eliminates the hassle of cargo handling workers after they arrive at their destination floor, and also eliminates the possibility of damage to the door when carrying out cargo.
