Description

Description: [Industrial field of application] The present invention relates to an elevator operating apparatus having two entrances and exits in one car.

[Conventional technology]

Recently, many elevators have a structure in which doors are formed in two directions, for example, by providing doors at the front and rear of one car, based on the structural needs of buildings and the desire to use elevators from inside and outside the building. Is installed. In this type of elevator, it is general that normal operation and dedicated operation can be performed.

The normal operation is an operation in which each of the front door and the rear door is used for getting on and off. That is, the front door hall is equipped with front hall calls, and the rear door hall is equipped with devices for generating rear hall calls.In one car, the front operation panel equipped with the front destination button on the front door side, the rear A rear operation panel equipped with a rear destination button is provided on each side door, and the front door services the front-side landing calls and car calls, and the rear-side landing calls and car calls. Is driven to service the rear door. In this case, since it may be dangerous to open both doors at the same time, it is always controlled so that only one door performs the door opening service.

The dedicated operation is a special operation used by, for example, a building manager. In this operation, when a landing call is not serviced, if the destination button on the destination floor is operated and then the door close button is operated until the door is completely closed, the car call is serviced.

[Problems to be solved by the invention]

The following problems arise in the elevator driving apparatus having the car having the two doorways of the front door and the rear door as described above. For example, consider a case where the building manager travels from the first floor to the third floor by using the front door in the dedicated operation in the elevator installed in a four-story building. In this case, the building manager enters the car through the front door, registers the front car call on the third floor with the front operation panel, and operates the door close button. When you arrive at the 3rd floor, the car call on the 3rd floor is canceled and the front door opens. However, if the building manager wants to go to the rear landing on the 3rd floor when arriving on the 3rd floor by such dedicated operation,
According to the conventional driving device, the car call cannot be registered on the floor where the elevator is stopped, so that the car cannot be immediately exited. Therefore, in order to get to the rear landing on the 3rd floor, it is necessary to take the procedure of traveling to the upper or lower floor once and then generating the rear car call again, which requires a very troublesome driving operation. It had the drawback that

The present invention has been made to solve such problems, and it is an object of the present invention to obtain an elevator driving device that can easily go to a landing on the side opposite to the door-opening side on the stop floor during dedicated operation. It is intended.

[Means for solving problems]

In order to achieve the above-mentioned object, the present invention has two cages.
In addition to providing an entrance door on one side and arranging an operation panel provided with a destination button corresponding to each of the above-mentioned entrance doors in the car, a normal operation for servicing a car call and a landing call by the car destination button,
In an elevator equipped with a dedicated operation that serves only car calls, the door opening side door is closed based on the operation inside the car of the destination button on the stop floor of the operation panel on the door closing side provided in the car during dedicated operation. Also, the present invention is to provide an elevator driving apparatus characterized by being provided with a control circuit means for opening a door on a door closing side and selectively opening both of two entrance doors on a stop floor. .

[Action]

According to the present invention, in an elevator equipped with a car having two entrances and exits, when the destination button on the stop floor on the operation panel on the door close side is operated at a certain stop floor during exclusive operation, the door on the door open side is closed. You can open the door on the door-closed side and freely pass through at the stop floor.

Further, (13F) is a door closing command button on the front operation panel, which is closed by the door closing operation, and (5Fb) is a normally open contact of the service request relay, which is open when there is no service request.

In the above, normally closed contact (9F) and normally open contact (SPa), normally closed contact (FSc) and (6Fb) and (7Fb), normally closed contact (10F) and normally open contact (12Fa), which will be described later. The lock switch contact (11Rb) on the side door, the lock switch contact (11Fb) on the front door, the door close command button (13F), and the normally open contact (5Fb) are connected in series, respectively. The open contacts (RSb) are connected in parallel, and the door control relay (12F) is connected in series to the parallel circuit. Also, contact (FSa), (FS
b) and the lock switch contact (11Fb) are arranged on the rear door control circuit (R) side.

On the other hand, the control circuit for the rear door (R) is also the control circuit for the front door (F)
It has the same circuit configuration as. That is, (1R) ~ (4R)
Destination buttons on the 1st to 4th floors provided in the basket, (RS) is a rear door service command relay, (RSb) is a normally open contact of the relay (RS), and (RSa) and (RSc) are relays ( RS) normally closed contact, (5Ra) is normally closed contact for service request relay, (5Rb)

Next, (9R) is the normally closed contact of the rear door non-interference time setting time relay, (10R) is the normally closed contact of the floor alignment position detection relay, and (11Ra) and (11Rb) are the lock switch contacts of the rear door. , (12R) is a door control relay for the rear door, (12Ra) is a normally open contact by the door control relay (12R), and (13R) is a door closing command button on the rear operation panel.

The circuit elements in the rear door control circuit (R) correspond to the circuit elements in the same position in the front door control circuit (F) in the figure.

Next, the operation of the elevator having the control circuit having the above configuration will be described. Now, let's say that the elevator car is waiting on the first floor with the front door open.
It is assumed that maintenance personnel, etc., board the dedicated operation switching switch. As a result, the elevator is switched to the well-known dedicated operation, and the normally open contacts (SPa) and (SPb) of the dedicated operation relay are closed. Next, when the building manager registers a car call on the third floor of the front operation panel and further operates the door close command button (13F), (+ B)-
The (13F)-(5Fb)-(12F)-(-B) circuit activates the door control relay (12F) of the front door, the front door closes, and the car starts running after the door is closed. As described above, in the dedicated operation, the door is closed by operating the door close command button (13F) while the service is requested.

When the floor selector arrives at the third floor, the well-known stop determination circuit determines to stop the front car call on the third floor. When it is decided to stop to the front car call, the normally open contact (7Fa) of the front car call stop decision relay is closed, and since the call on the third floor is only the front call, the normally open contact (8F) of the front door priority door open service command relay is Closed, (+ B)-(7Fa)-(8F)-(RSa)-(FS)-
(-B) activates the front door service command relay (FS).

When the elevator car reaches the third floor, the normally closed contacts (10F) and (10R) of the floor alignment position detection relay open.
This deactivates the door control relay (12F) on the front door, and the front door opens. However, since the normally open contact (FSb) of the rear door is closed by the front door service command relay, the (+ B)-(FSb)-(12R)-(-B) circuit controls the rear door. The relay (12R) is energized, and the rear door holds the door closed state.

Next, after the building manager exited the front door and completed the work, 3
When an errand occurs on the rear door side of the floor and goes out to the rear side, the building manager operates the destination button (3R) on the third floor of the rear operation panel. Then (+ B)-(3R)-(5Ra)-(SPb)-(ST
b)-(RS)-(-B) circuit activates the rear door service command relay (RS), and its normally closed contact (RSa) opens, so the front door service command relay (FS) disappears. Energized,
And since the normally open contact (RSb) is closed (+ B)-(RSb)-
(12F)-(-B) activates the door control relay (12F) for the front door, and the front door closes. When the front door completes closing and the front door is locked, the normally closed contact (11Fb) of the lock switch
The door control relay (12R) is deactivated because the condition to activate the door control relay (12R) on the rear door is removed. When the door control relay (12R) is deactivated, the rear door starts to open, allowing the building manager to go out to the rear of the third floor.

In the above embodiment, the exclusive operation related to the front door is performed, and the operation of moving to the rear side by using the rear door has been described, but the exclusive operation related to the rear door can be similarly performed to the front side. . As described above, in the elevator driving apparatus according to the present invention, in the dedicated operation state, both of the two entrance doors can be selectively opened at any stop floor and the passage can be performed. . In this case, when one door is opened, the other door is always closed.

In the above-described embodiment, the door-closing side door is opened by operating the door-closing side operation panel, but the door-opening side operation panel may be used to open the door.

〔The invention's effect〕

As described above, according to the present invention, in an elevator driving device having two entrance doors in a car and capable of performing a normal operation and a dedicated operation, the elevator is provided in the car at any stop floor during the dedicated operation. The door opening side door is closed and the door closing side door is opened based on the inside operation of the destination button on the stop floor of the door closing side operation panel, and either of the two entrance doors is selected on the stop floor. Since the control circuit means for dynamically opening the door is provided, it is possible to use either of the two entrances and exits at the stop floor in the dedicated operation state, and it is possible to freely pass through.
