Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator control device, and more particularly to an elevator control device capable of setting a sub-reference floor to an elevator having a reference floor return function.

<Prior Art> Generally, an elevator employs a so-called standard floor return system in which a car responding to a final car call is automatically returned to a standard floor having an entrance to and exit from the outside. In this standard floor return type elevator, when a passenger gets out of the car and there is no other car call, the elevator car is immediately returned to the standard floor which is usually set to the first floor.

On the other hand, there is an elevator user who wants to complete a work in a predetermined floor of a building in a relatively short time and quickly move to another floor. This type of user is a post office worker who delivers mail to each floor of the building or a manager who visits each floor of the building for inspection work.

For such users, when they get off the elevator car on a certain floor, finish the work in a short time, and return to the landing, the car has already returned to the standard floor and called a car. It is inconvenient to have to wait for the car to arrive.
On the other hand, it is clear that such an operating system is inefficient and the electric bill is wasted.

A method of improving such a situation is proposed in Japanese Utility Model Laid-Open No. 57-106665, and in the proposed method, a switch is provided in the car to shut off the reference floor return function, and the switch shuts off the reference floor return function. It is configured to do. in this case,
Although the normal call registration is performed, or the reference return function is restored when a predetermined time has elapsed after the call disappeared.

<Problems to be solved by the invention> In the previously proposed method described above, for example, when a manager inspects each floor, an elevator call is often generated during inspection except for inspection at midnight, When the car returns to the landing, the car that has finished the service often returns to the standard floor.

Therefore, as a result, the cutoff of the standard floor return function does not function effectively, and the inefficient operation method is still applied.

The present invention has been made in view of the current state of the elevator control device as described above, and its purpose is to set a sub reference floor for a predetermined time set in advance to a desired floor, and an elevator call is generated. However, if the service for the final car call is completed within this predetermined time, the car is to provide a control device for the elevator that returns to the sub-standard floor.

<Means for Solving Problems> In order to achieve the above-mentioned object, the present invention provides a car that responds to a car call between a plurality of floors, and responds to a final car call. In an elevator control device that works to return a car to a preset reference floor, a sub-reference floor setting means for setting a sub-reference floor for each floor is provided, and a sub-reference floor setting means is provided in the car. When the operation floor is provided with an operation button for operation and the car is landed on the selected floor and the selected floor is set as the sub-reference floor by operating the operation button, the sub-reference floor setting means of the selected floor is set to a predetermined value. While the time limit is set and the sub-reference floor setting means is set for the time limit, the car responds to the car call of each floor and, after responding to the final car call, generates the car call of the sub-reference floor. , Return the car to the sub-standard floor Equipped with a means for performing.

<Operation> In the elevator control device according to the present invention, an elevator user who finishes work on a certain floor in a short time and quickly shifts to another floor, for example, a manager who is inspecting each floor of a building, A sub-reference floor can be set on the floor for a predetermined time. In this case, if the elevator user operates the operation button of the sub-reference floor setting relay in the car, the car will eventually move to the sub-reference floor even if the car call is answered within the predetermined time. Since it will be returned to the set floor,
The user can shorten the waiting time and the elevator can be operated efficiently.

When is turned on, the detection relay 1 is self-held.

Therefore, the car is returned to the first floor, which is the reference floor, by a control circuit (not shown).

Next, the case of an elevator when the sub-standard floor is selected as the 7th floor will be described.

When a customer who wants to select the sub-standard floor as the 7th floor gets in the car on the 1st floor and presses the car call push button 7B _a for the 7th floor, the car ascends and reaches the 7th floor as described above. To do.

When the passenger presses the sub-reference floor setting push button C in the car that arrives on the 7th floor, the contact 7F _a is turned off by the arrival of the car on the 7th floor.
Since it is N, the power supply terminal P, the push button C, the contact 7F _a , the contact 6P _b7 , the sub reference floor setting relay 7P and the power supply terminal N form a closed circuit. Since the sub-reference floor setting relay 7P is energized, the contact 7P _a7 turns ON, and the contact 7P _a2 also turns ON.

Therefore, a closed circuit is formed by the power supply terminal P, the contact 7P _a2 , the timer T, and the power supply terminal N, and the timer T starts operating. The contact T _a is turned on by the operation of the timer T.

Since the contact T _a turns ON, the power supply terminal P, the contact T _a , the contact 7
P _a7 , contact 6P _{b7 to} contact 2P _b7 , sub reference floor setting relay 7P
A closed circuit is formed by the power supply terminal N and the sub-reference floor setting relay 7P is held by itself.

If a hall call for the second floor occurs in this state, the car will run toward the second floor under the control of a control circuit (not shown).

The operating time of the timer T is set to, for example, 10 minutes, and if there is no final call to the car within this operating time, the power terminal P, the contact 7P _a1 , the contact 8b ₇ , the contact 7F _b , the car call detection relay 7 and Due to the closed circuit formed by the power supply terminal N, the detection relay 7 is energized to bring the car to the 7th floor.
The car will return to the 7th floor, which is set as the sub-standard floor. In this case, since the terminal _Tb is OFF, the detection relay 1 is not energized.

After the lapse of the predetermined time set by the timer T, the contact _Ta turns off.
Therefore, the sub-reference floor setting relay 7P is deactivated and the contact 7P
_a1 is turned off, and the detection relay 7 is deenergized.

At the same time, the contact T _b turns on, so the power supply terminal P, the contact 8 b ₁ ,
A closed circuit is formed by the contact point T _b , the contact point 1F _b , the detection relay 1 and the power supply terminal N, and the detection relay is energized so that the car 1
Return service to the standard floor of the floor.

In this way, the customer who has set the sub-standard floor in the elevator, such as a manager or a post office worker, completes the work on the floor within the predetermined time set by the timer T, and returns to the landing site within the predetermined time. Even if there is a car call to the car, the car will always return to the floor if the last car call has been answered within a predetermined time, so you can use the elevator with a short waiting time. . This is also advantageous in terms of operating costs because no unnecessary return operation is performed in the operation of the elevator.

<Effects of the Invention> As described in detail above, according to the present invention, a sub-reference floor is set in a necessary floor, and after the setting, within a predetermined time, the car responds to a car call of each floor. Since the car that responds to the final car call is operated to return to the sub-standard floor, the work of each passenger on each floor can be efficiently performed, and wasteful operation of the car can be omitted. The effect is that the car can be operated efficiently.
