Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator driving device, and more particularly to an elevator driving device in a building having an entrance floor on at least two floors.

[Conventional technology]

Generally, in an elevator in a high-rise building, group management control is performed in advance so as to perform attendance pattern operation in the attendance time zone in order to improve service to users. As an elevator of this kind, for example, Japanese Patent Laid-Open No. 59-124671. The one disclosed in the publication is known.

By the way, in the building where such an elevator is installed, apart from the first entrance floor above the ground, there is a second underground building that allows direct entry from a subway station, which is one of the urban transportation systems. Some have an entrance floor. In an elevator in such a building, in consideration of passengers who come to work by using the subway, when the attendance pattern operation is performed, the entrance floor of the second entrance / exit is set as the second reference floor, and the elevator is returned to the floor. It was configured to manage departures.

[Problems to be Solved by the Invention] However, in the above-described conventional elevator driving apparatus, when a train arrives at a station and passengers rush to the landing on the second doorway floor, Only the passengers from the hall will fill up the car, and passengers waiting at the hall on the first entrance floor will not be able to use this elevator. Therefore, the passengers waiting at the hall on the first doorway will be able to use the elevator only when the passengers rushing to the hall on the second doorway are dealt with and the passengers on the second floor are full. Must be released. However, due to the large number of trains operating during the work hours, it is difficult to release the full capacity at the second doorway, and passengers waiting at the first floor of the doorway will wait forever. There was a problem.

The present invention has been made to solve the above problems,
An object of the invention is to provide an elevator driving device which improves the service to each customer at the halls on the two entrance floors.

[Means for solving problems]

The above-mentioned object is an elevator installed in a building having an entrance floor on at least one floor, and a driving device for performing a attendance pattern operation that reverses from descending operation to ascending operation at the lowest entrance floor during work hours. Having, the regulation load value at the time of attendance pattern operation in the load regulation device for regulating the loading load of the car is set for each of the entrance floors, and the regulation load value of the entrance floor to stop in advance, This can be achieved by setting the load to be smaller than the regulation load value of the entrance floor to be stopped next.

[Action]

With the above configuration, in the present invention, when the elevator starts the attendance pattern operation, the descending operation is reversed to the ascending operation at the lowest entrance floor. At that time, the regulated load value in the load stacking regulation device is set to be smaller than the regulated load value of the entrance floor to be stopped next at the entrance floor that stops first, and is set to, for example, 50% of the rated value. Therefore, even after the load of the car that has reached the lowest entrance floor by the attendance pattern operation reaches the regulation load value, passengers can be allowed to board until it reaches a larger regulation load value at the entrance floor to be stopped next.

 Embodiments of the present invention will be described below with reference to the drawings.

The drawing is a circuit diagram of an elevator driving device, which is configured by being connected between power sources P and N.

First, between the power sources P and N, the attendance pattern operation command circuit X that detects the attendance time zone and issues an attendance pattern operation command is connected. The second load detector WA is connected between the power supplies P and N.
And a load detection operation relay A are connected in series, and the load detector WA is provided at a landing on the second floor of the doorway such as underground, and the loading load in the car is a predetermined value, for example, the rated loading. It is configured to activate and close the contacts when 50% of the volume is reached. The load detection operation relay A is energized by closing the contacts of the load detector WA, and its normally open contact
Close A ₁ and A ₂ .

Further, a floor position detector F and a floor relay B are connected in series between the power sources P and N. The floor position detector F is composed of contacts that are closed when the car reaches the second entrance floor, that is, the entrance floor in the basement. By this closing, the floor relay B is energized, Close the normally open contacts B ₁ , B ₂ . Further, the signal contact X _{1 of the} attendance pattern operation command circuit X, the normally open contact A ₁ of the load detection operation relay A, and the normally open contact B ₁ of the floor relay B
And a start prevention relay 65W are connected in series between the power supplies P and N. The lower entrance floor return circuit Y, which is connected between the connection point of the signal contact X ₁ and the normally open contact A ₁ and the power supply N, issues a return command to return the car to the basement floor, which is the lower entrance floor. The first load detector WB connected between the connection point of the normally open contact B ₁ and the start prevention relay 65W and the power source P is provided at the landing on the ground floor, which is the first entrance floor, The load in the car is the second predetermined value, for example 110 of the rated load.
When it reaches%, it operates and closes its normally open contacts B ₁ , B ₂ . Also, normally open contacts A ₂ and B ₂ and signal contact X ₂
And the notification device Z are connected in series between the power sources P and N, and the notification device Z is the reason why the elevator is not activated when the first load detector WA operates, for example, "a passenger on the lobby floor also You can get on, so please get off the elevator until the buzzer stops. "

Next, the operation of this driving device will be described.

First, the attendance pattern operation command circuit X issues an attendance pattern operation command at a predetermined attendance time zone, and its signal contact
Close X ₁ and X ₂ . For this reason, the power P ...... signal contact X ₁ ......
Lower entrance floor return circuit Y ... A power supply N circuit is formed,
The lower entrance floor return circuit Y is activated to issue a return command to the car, and start service to passengers waiting at the basement floor of the lower entrance floor.

Therefore, the floor position detector F is closed, the floor relay B is connected between the power sources P and N and is energized, and the normally open contacts B ₁ and B ₂ are closed. In this state, the passengers on the lower entrance floor, which is the lower entrance floor, get into the car, but when the load in the car reaches the first predetermined value, that is, 50% of the rated load, the first The load detector WA operates, and a circuit of the power source P ...

... Notification device Z ... The notification device Z is operated by the circuit of the power supply N. Therefore, while the elevator operation is blocked,
The alarm device Z broadcasts the reason for the operation prevention, that is, "Because passengers on the lobby floor can also be seated, please get off the elevator to the number of people who stop the buzzer" on the lower entrance floor. This broadcast continues until the first load detector WA fails.

In response to this broadcast, when the user in the car gets off and the operation of the first load detector WA stops, the load detection operation relay A
Is de-energized, the normally open contacts A ₁ , A ₂ are opened, the operation of the alarm device Z is stopped, and the start prevention relay 65W is de-energized accordingly. As a result, the operation of the car is started and the upper entrance Reach the floor above the ground floor. At this time, the inside of the car is less than 50% of the rated load, and due to the opening of the floor position detector F, the floor relay B is deactivated and the normally open contacts B ₁ and B ₂ are opened. There is.

In this state, when a passenger at the landing on the ground entrance floor, which is the upper entrance floor, gets into the car and the load reaches a second predetermined amount, that is, 110% of the rated load, the second load detector WB detects this and power source P …… load detector WB ……
Start prevention relay 65W: A circuit of the power supply N is formed, and the operation of the elevator is again stopped by the activation of the start prevention relay 65W. This is informed by a buzzer, etc., similar to a normal elevator, and when the appropriate load is reached, the operation of the second load detector WB stops and the start prevention relay 65W is deactivated to operate the elevator. Is started.

As can be seen from this description, by the load detectors WA, WB and the activation prevention relay 65W, a load loading control device is configured for each of the two entrance floors, and the load loading control device of the entrance floor that stops first is It may be set to be smaller than the regulation value of the load on the load regulation device on the entrance floor to be stopped. In this respect, in the present embodiment, the former regulation value is set to 50% of the rated load, so that the service to the users on both entrance floors can be performed fairly, and the users on the upper entrance floor can be completely eliminated as in the conventional case. It is possible to eliminate the situation where you cannot get on. In addition, the regulation values of these load regulation devices can be determined according to the situation of the customer on each entrance floor. In any case, by providing the notifying device Z in the load stacking restricting device on the preceding entrance floor, it is possible to alleviate the frustration of the passengers who are unable to board here.

〔The invention's effect〕

As described above, according to the present invention, when the attendance pattern operation is performed, the regulation load value in the load stacking regulation device is lower than the regulation load value of the front floor that stops next in the front floor that stops first. Since it is set to be small, regardless of the hall call such as the entrance floor, even after the load of the car reaching the lowest entrance floor reaches the regulated load value, the next stop floor Since passengers can be allowed to board until a larger regulation load value is reached, fair service can be provided to passengers at the entrance floor that will stop next, without being biased toward passengers at the lowest entrance floor. .
