Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a device for operating an elevator, particularly a device for reversing the direction of operation. [Elevator/Escalator J for Building Equipment New Edition 1st Printing (August 20, 1972) Ohmsha Co., Ltd.

As stated in p. 30 lines 6-7.

The car that is running up is reversed direction at the highest floor to be called out and is operated so as to shift to down run.

This is called automatic maximum reversal. An example thereof is shown in FIG.

In the figure, Ill ~ (1 (IH floors 1st to 10th floors, (
3a) (5a) to (9a) are on the 3rd floor (31, 5th floor (5)
This is a down call registered by the down button on the 9th floor (9).

In recent years, buildings have become increasingly high-rise, and the number of high-rise residential buildings in particular is increasing. In these high-rise residential buildings, there are many requests to descend from each residential floor to the first floor (as shown in Figure 5, there is a strong tendency for there to be many calls to descend from each floor).

At this time, the car ascends as shown by arrow A, reverses its direction in the downward direction at the 9th floor (9), which is the highest called floor, and reaches the 9th floor (9+).
, 8th floor +81. The train is operated to the 1st floor in response to the 7th floor (7)... and so on, in response to the down call.

[Problem that the invention seeks to solve]

In the conventional elevator operating system as described above.

I always drive up to the highest called floor.

During downhill operation, while responding to calls from the upper floors one after another,
The car becomes full, and the car often passes through in response to calls from lower floors. In the case of Figure 5, if the 6th floor (6) becomes full during downhill operation, it is expected that there will be some unloaded items on the 6th floor (6), and the 5th floor (5) and 3rd floor will be left unloaded.
Passengers waiting on floor (3) will not be able to board the train at all. For this reason, there is a problem in that the elevator is often unavailable for passengers waiting to descend from the lower floors.

This invention was made in order to solve the above problem, and provides services to waiting passengers who are left behind due to full boarding during down-bound driving and to waiting passengers on the floors that have been passed.

To provide an elevator operating device capable of equally servicing upper and lower floors.

[Means for solving problems]

The elevator operation device according to the present invention includes a full floor memory circuit that stores the floor at which the car is full during down-down operation, and a full-floor memory circuit that stores the full floor memory circuit when the full-floor memory circuit is operated. is provided with a direction reversal circuit that causes the train to operate in the down direction at the floor where it has been stored.

[Effect]

In this invention, the car is reversed in the backward direction in response to the highest floor to be reached during uphill operation.

If the car becomes full during the downhill operation, the direction of the car is reversed at the full floor during the ninth uphill operation, and the car is shifted to the downhill operation.

The relay contact, tiυ, is a time-limited relay contact for holding the driving direction that closes when the car runs, stops, and opens after a certain period of time has passed after the P-opening is completed.

(17a) is a normally open contact number 7, and +11 is a fullness detection contact that is provided in the car and closes when the car is full.

In Figure 4, (2a)t(41L) is the second floor (2) and 4th floor.
This is a down call registered by the down button on the floor (4).

Next, the operation of this embodiment will be explained.

Assuming that the car is currently on the first floor, the car position detection relay contact (1st) on the first floor is open. here.

If a down call (2a) to (5a) for the second floor (fourth to fifth floor (5)) is registered, the down call registration relay contacts (2D) to (5D) for the second to fifth floor are closed. So, (+)

Upward operation relay contact α and traveling relay contact (10a)

Further, the driving direction holding time relay contact I is also closed. When the car rises, the position detection relay contacts (28a) to (48a) of the cars on the second to fourth floors are sequentially opened.

Since the contact (5S) is closed, the upward direction command relay (8) is held. When the car approaches the fifth floor (5), the contact (5S) opens. At this time, since the traveling relay contact (10b) is open, the upper 9 direction command relay (8) is deenergized, the contact (8a) I/'i is opened, and the contact (sb).

The downward direction command relay (9) is energized, and the contact (9a),

The stop command relay is energized by the circuit indicated by -(→), and is self-held by closing the contact (17a).

As a result, the car reverses its direction and stops at the fifth floor (5), which is the highest floor to be missed. When the car stops, the traveling relay contact (1

Car L operates downhill, and by energizing stop command relay α by closing stop detection circuit I, the car stops in response to downbound calls from the 4th floor to 2nd floor, and activates downcall registration relay (4D). )

When the basket on the third floor (3) becomes full, some of the waiting customers on the third floor (3) are left unloaded. Also, the car goes to the tll on the 1st floor on the 2nd floor (2nd floor passes through, so the circuit is omitted).

Passengers waiting on the second floor (2) are not allowed to ride the car.

Assume that when this car reaches the first floor (1) and then runs up to the first stage, down calls for the second to fifth floors are registered again. When the basket rises and comes to the third floor (3).

The car position detection relay contact (58a) is opened. At this time, contact (5R1))? (4Rb) I/'i is open, so the up direction command relay (8) Fi is deenergized and the contact (ab) is closed.

to reverse the direction. At this time, as described above, the direction reversal detection relay αe is energized and the contact (16a) is opened, so the full floor memory relays (3R) and (4R) are deenergized and the contacts (3Ra) and ( 4Ra) is open.

Contacts (31t+) and (4Rb) are closed to prepare for the second storage.

Now, the basket is loaded with the last unloaded customers on the third floor (3).

After driving down and stopping on the second floor (2) to pick up waiting passengers.

You will be heading to the first floor (1).

Please note that no occupancy occurred, and the occupancy floor memory relay (2R)~(
4R) are all deenergized, it is clear that the car will run up 9 to the highest called floor (in this case, the 5th floor (5)).

In the example, the number of floors of the building is 5, and the full floor is the 3rd floor (
3), but these may be on any floor.

In addition, the fullness detection contacts a and E can be used as contacts of a load detection device that measures the load of passengers in the car, contacts of a mud switch provided on the car floor, etc.

〔Effect of the invention〕

As explained above, in this invention, the car responds to the floor with the highest down call and then reverses direction.

If the car becomes full during down-bound driving, the floor is memorized, and during the second up-going operation, the direction of the car is reversed at the above-mentioned full floor and the car is shifted to Down 9 operation. Customers waiting on the same floor can be given priority service on the next drive.

This has the effect of being able to serve the upper floors and the F-direction floors in the 10th order.
