Description

[Detailed Description of the Invention] This invention relates to an improvement of a device for operating an elevator.

Recently, there has been a demand for elevators that are easy to operate even for physically disabled people using wheelchairs (hereinafter referred to as disabled people).

If the number of elevators is sufficient, it is possible to install an elevator exclusively for the disabled in addition to the regular elevators, but in general, regular elevators and elevators for the disabled cannot be shared. many.

In this case, measures such as providing a dedicated landing button and destination button in addition to the normal landing button and destination button, and slowing down the opening and closing speed of the door when the dedicated call button is pressed, that is, when used by a disabled person. Therefore, it is common practice to ensure that even people with disabilities can use elevators safely.

On the other hand, elevators are usually equipped with a load detection device, and the load inside the car is determined to be 80% of the set value, for example 80% of the rated capacity.
When the car reaches this point, it is considered full, and even if there is a call for a landing on the floor the car is traveling on, the car will pass without responding.

However, in the above-mentioned elevator that is also used for the disabled, even if the fullness detection is set to 80%, there is no particular problem during normal operation, but there is the following problem during dedicated operation.

That is, when a disabled person in a wheelchair gets into the car, other wheelchair users or a large number of general users cannot get into the car.

Therefore, the car internal load almost never reaches the above 80%.

Therefore, if there is a landing call on a floor where the car is traveling,
The car will come to a stop on that floor, but for the reasons mentioned above, there is no longer room for people to get into the car, and the car will stop in vain.

This invention is intended to improve the above-mentioned defects, and the purpose is to provide an elevator operating device that does not needlessly stop in response to a hall call when there are specific users such as people with disabilities. do.

An embodiment of this invention will be described below with reference to FIGS. 1 to 3.

In the figure, 10 and - are DC power supplies, IA to 4A are the up-hall call buttons for the 1st to 4th floors, 1B to 4B are the up-hall up call registration relays, lBa-4Ba are the respective normally open contacts, l
BX to 4BX are the hall up call release relays that de-energize the hall up call registration relays IB to 4B, respectively, when energized. IC-4C is also a dedicated hall up call button, ID-
4D is also a dedicated landing board up call registration relay, and lDa
, 1Db~4Da, 4Db are each normally open contact,
Dedicated hall inbound call release relays IDX to 4DX deenergize the dedicated hall inbound call registration relays ID to 4D when energized, respectively. 5F is also a car call registration relay, IFa ~ 5Fa are each normally open contact, 1G ~ 5G
is also a dedicated destination button, IH ~ 5H is also a dedicated car call registration relay, i Ha, l Hb ~ 5H
a, 5 Hb are each normally open contact, iIa ~ 41
a...iIe to 4Ie are car position contacts that close when the car is on the 1st to 4th floors, lIf to 5If are car position contacts for the 1st to 5th floors that also open, and 6 to 9 are in the opposite direction. A current blocking rectifier; 10a to 10c are upstream relay contacts that close when the car is running in the upstream direction; 11 is a deceleration command relay contact that closes when a deceleration command is issued to the car;
12 is an 80% detection contact that opens when the load inside the car reaches 80% of the rated capacity, 13 is a 40% detection contact that opens when the same reaches <40%, and 14 stops at the next floor when energized. 15 is a dedicated operation relay that commands the above-mentioned dedicated operation when energized, and 15a
, 15b is its normally open contact, 15c is its normally closed contact, 1
Reference numeral 6 designates a relay contact for setting the door opening time, which is closed while the car is running and opened after the door has stopped opening.

Next, the operation of this embodiment will be explained.

Now, if the car is empty and on the first floor, and the landing hall up call button 2A on the second floor is pressed, the hall up call registration relay 2
B is energized and self-retains by closing contact 2Ba.

By means of well-known elevator control circuitry, the car is commanded in the up direction, and up direction relay contacts 10a, 10b are closed.

When the car rises and approaches the second floor, car position contact 2Ia,
21b is closed.

(+) = 2Ba 2Ia-6-10a-15c
The hall call stop determination relay 14 is energized by the circuit m12-14- (-).

After that, when the deceleration command relay contact 11 closes, (+).

The circuit 2Ba-2BX-2Ib-8-10b-11-(-) energizes the hall up call release relay 28X and deenergizes the second floor hall up call registration relay 2B.

If the car stops on the 2nd floor and a waiting customer gets into the car and presses the destination button 4E on the 4th floor, the car call registration relay 4
F is energized and maintains itself by closing contact 4Fa.

The car rises further and as it approaches the 4th floor, car position contact 4I
f is opened and car call registration relay 4F is deenergized.

Further, the car is stopped at the fourth floor by the operation of a car call stop determination relay (not shown).

During this period, when the load inside the car reaches 80%, the 80% detection contact 12 opens, so even if a landing call is registered at an intermediate floor, the stop decision relay 14 is not energized, and the car stops at that floor. pass.

Next, if the car is empty and is on the first floor and the second floor exclusive landing up call button 2C is pressed, the exclusive landing up call registration relay 2D is energized and self-maintained by closing the contact point 2Da.

At the same time, contact 2Db is also closed.

When the car approaches the second floor, car position contacts 2IC and 2Id
Ha closes, (+)-2Da-2Ic-7-10a-15
The hall call stop determination relay 14 is energized by the circuit cm12-14-().

After that, when the deceleration command relay contact 11 closes, (+)
-2Da -2DX -2Id -9-10b-11-
The (-) circuit energizes the dedicated hall call release relay 2DX, and deenergizes the second floor dedicated hall up call registration relay 2D.

Also, since contacts 2Ie and 10c are also closed, (+)
-2Db-21e-10cm15- () The dedicated operation relay 15 is energized and the contact 15a is closed.

At this time, since the door opening time setting relay contact 16 is closed, the dedicated operation relay 15 is self-maintained.

At the same time, contact 15b is closed and contact 15C is opened.

The car is now in dedicated operation, and the opening and closing speed of the doors is slowed down, and a message indicating that the car is in dedicated operation is displayed.

When the car stops on the second floor and a disabled person gets into the car and presses the dedicated destination button 4G for the fourth floor, the dedicated car call registration relay 4H is energized and self-holds by closing the contact 4Ha.

Further, contact 4Hb is also closed.

When the car approaches the 4th floor, car position contact 4If opens,
The dedicated car call registration relay 4H is deenergized.

The car then stops on the fourth floor.

When the car opens its door, the door opening time setting relay contact 16 opens.

At this time, since the contact 4Hb is open, the exclusive operation relay 15 is deenergized and the exclusive operation is canceled.

During this period, when the car load reaches 40%, the 40% detection contact 13 opens, so even if a landing call is registered on an intermediate floor, the stop decision relay 14 is not energized, and the car stops at that floor. pass.

Note that although the explanation has been made regarding the up-hall call, the same explanation can be applied to the down-hall call.

The system will also be applied not only to driving exclusively for the disabled, but also to driving exclusively for important customers.

In other words, in the case of an important passenger who wants to avoid riding with other passengers, that objective can be achieved by lowering the set value of the car load and passing the hall call.

As explained above, with this invention, during dedicated operation using a dedicated call button, the car passes through the floor where a hall call is registered on the way, even if the load inside the car is lower than during normal operation using a normal call button. Therefore, it is possible to reduce unnecessary stops that occur when it is undesirable to allow entry.
