Abstract

PURPOSE:To dissolve the trouble of a cargo handling worker after the arrival to the object floor by storing the operated address floor and the action of an open extending button and operating a door open time extending device at the stored address floor after a cage reaches it. CONSTITUTION:When a cargo handling worker is to convey a cargo with an elevator from the first floor to the floor M, he fist pushes an open time extending button 4, an extension commanding timer 9 counts the time via actions of relays 6 and 7, and the ordinary door closing action is stopped. When a hand is released from the button 4, the extension commanding timer 9 starts the time counting, the door is not closed until the time counting is completed, and the cargo is carried in. When an address floor registering button 12 is pushed, a cage is run to the object floor. When the button 4 is pushed before the time limit of a timer 20, an open extension reserve floor registering relay 24 is self-held. When the cage reaches the floor M, the door is kept open until the time counting of the extension commanding timer 9 is completed. The operability of the cargo handling work can be improved.

In order to take time to put in and take out beds and luggage, a door opening time extension button is provided, and by pressing it, the door is open for an extended period of time.
An elevator door control device as shown in Japanese Patent No. 8 is provided.

[Problem to be solved by the invention]

By the way, while driving to the desired floor after loading the luggage into the car,
When passengers board the train in response to the call at the landing on the middle floor,
Depending on the space inside the car, in some cases the cargo handler may be forced to go to the back of the car. When the car arrives at the floor desired by the cargo handler and the cargo is unloaded, especially when a trolley is used, 1. Normally, when carrying the trolley into the cage, the cargo handler must take care to make it easy to carry the trolley into the cage. In order to do this, the handle of the trolley is placed in the direction of the depth of the car, and as a result, one has to go to the driver's panel, operate the opening extension button, and then return to the handle position. It's a hassle, so I don't have to operate the door extension button to extend the opening time of the door to bring in luggage. 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 luggage is still being carried out. As a result, the normal door closing time occurs during the loading of cargo, and the door may close and collide with a truck or the like, causing damage to the door. Additionally, many of the causes of door damage are due to the above-mentioned factors.

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 for solving ill 1 problem) In order to achieve the above object, the present invention provides a car destination floor registration button and an opening extension button provided on an in-car passage board for moving a car to an operated floor. When manipulated.

An elevator operating device having a door opening time extension device for extending a door opening time.

When a car destination floor registration button is operated and an opening extension button is operated within a predetermined time after the car is operated by the destination floor registration button, the operated destination floor and the operation of the floor extension button are memorized;
The present invention is characterized by comprising a circuit that operates the door opening time extension device at the stored destination floor when the car arrives at that floor.

[Effect]

In the present invention, during cargo handling work, it is possible to reserve the door opening extension operation required when carrying out cargo from the car before arriving at the destination floor, so that the purpose of the cargo handling worker is achieved. This eliminates the inconvenience caused after arriving at the floor, and also eliminates the possibility of damage to the door during unloading of luggage.
