Description

[Detailed description of the invention] [Technical field of the invention] This invention relates to an elevator operation device that prioritizes the service of special call users such as wheelchair users and makes it easier for the dedicated call users to board the elevator. be.

[Prior art]

Recently, due to the structure of the building or to make it easier to get on and off the elevator, two doors with doors on the front and rear sides,
Two-gate elevators are increasingly being installed.

As mentioned above, this two-door, two-gate elevator has doors on the front and rear sides, and even if the structure of the building allows the elevator to be used only at the rear, by having a door on the opposite side, As mentioned above, it has the advantage of making it easier to get on and off.

Further, although the two-door, two-gate elevator has the above-mentioned advantages, it also has limitations in use.

During elevator service, when there are calls to be answered on both sides, if both doors are serviced at the same time, passengers in the car may be in danger, and passengers may get off on the opposite side, so always use one door first. It is supposed to be given priority service.

In this case, it usually has a priority service detection device that gives priority to servicing the calls on the front side.

Operation by special call for such elevators,
For example, when a well-known wheelchair operation for wheelchair users is provided, the conventional two-door, two-gate system has the following drawbacks.

For example, if there is a general hall call at the front of a certain floor and a wheelchair call at the rear, the elevator will open from the front door. At this time, many passengers boarded from the front landing, and when it became almost full,
In some cases, wheelchair users may not be able to use the elevator.

In addition, if there is a wheelchair user in the car who presses the rear destination button, and there is a front hall call at the front landing on the same floor, the service will be served from the front landing.
Even though there is a wheelchair user, general passengers board the car and the car becomes temporarily crowded.

As described above, when a two-door, two-gate elevator is provided with dedicated operation such as wheelchair operation, the method of uniformly providing door opening priority service has disadvantages in terms of use for general customers or wheelchair users.

[Summary of the idea]

This invention was made for the purpose of improving this drawback, and includes a dedicated call stop detection means, and when the dedicated call stop detection means operates, the door open priority service detection means is disabled, and priority service is given from the dedicated call. Therefore, we propose an elevator operating system that is very easy to use for both special customers and general customers.

A normally closed contact 23 of a lock switch for the rear door is connected between the power supply line L1 and the connection point P2.

Next, the operation of the elevator operating system configured as above will be explained.

The explanation will be based on a case where a 4-story building has a 2-door, 2-gate elevator, and there is also a wheelchair landing button at the rear landing and a wheelchair button for the rear side at the rear of the car. .

Now, when the elevator is waiting on the first floor,
Assume that the calls for the second floor ascending halls on the rear and front sides have been registered. The elevator runs in response to the call when well-known running conditions are met.

When the elevator floor selector reaches the second floor,
The normally closed contact 1 of the stop detection relay is closed, and a closed circuit of the power line L1, the normally open contact 1, the front priority service selection time relay 2, and the power line L2 is formed. As a result, the front priority service selection time relay 2 is energized. However, the front priority service selection time relay 2 does not operate immediately after being energized, but operates after a certain period of time.

Also, when the normally open contact 1 is closed, there are front and rear calls, so the normally open contact 3 of the stop detection relay due to the front hall call and the normally open contact 9a of the stop detection relay due to the rear hall call. is closed. As a result, power line L1 - normally open contact 3 - normally closed contact 4a - normally closed contact 5a - normally open contact 10
- Front priority service detection relay 7 - Power line L
2 closed circuits are formed.

As a result, the front priority service detection relay 7 is activated, but the rear priority service detection relay 4 is activated.
Since the front priority service selection time relay 2 is of a slow acting type, it is not energized. Also, in front of the second floor,
When a stop is detected in the rear call, the normally open contact 6 of the front service detection relay and the normally open contact 10 of the rear service detection relay are closed.

After this, when the elevator arrives at the door zone on the second floor, the normally open contact 17 of the door zone detection relay,
22 is open. As a result, the door control relay 14 for the front door is energized because the front hall call stop detection contact 15 is open, and the condition is not met, so it is deenergized and the front door is opened.

Since the normally open contact 7c of the front priority service detection relay 7 for the rear door is closed, the door control relay 19 for the rear door continues to be energized.

After this, when the non-interference time for the front door ends, the normally closed contact 1 of the time relay for setting the non-interference time for the front door
3 is closed, and the power line L1 - this normally closed contact 13
- Front door door control relay 14 - A closed circuit of the power line L2 is formed.

Along with this, this door control relay 1 for the front door
4 is energized and the front door closes. As a result, the normally open contact 6 of the front service detection relay is opened, the front priority service detection relay 7 is deenergized, and its normally closed contact 7b is closed.

By closing the normally closed contact 7b, the power line L1-
A closed circuit of normally open contact 9a - normally open contact 2a - normally closed contact 7b - normally open contact 10 - rear priority service detection relay 4 - power supply line L2 is formed, and this rear priority service detection relay 4 is energized. Ru. By energizing the rear priority service detection relay 4, the rear door opens after the front door completes closing.

Next, we will explain the case where there is a wheelchair. Assume that while the elevator is waiting on the first floor, a front-side ascending call and a rear-side ascending wheelchair call for the second floor are registered. The elevator runs in response to the call when well-known running conditions are met.

When the elevator floor selector reaches the second floor,
Normally open contact 1 of the stop detection relay similar to the above explanation is closed, and time limit relay 2 for front priority service selection is closed.
is energized.

Further, the normally open contact 3 of the front hall call stop detection relay and the normally open contact 12a of the stop detection relay due to a wheelchair hall call are closed.

By closing the normally open contact 12a, a closed circuit of power line L1-normally open contact 12a-wheelchair call stop detection relay 5-power line L2 is formed, and this wheelchair call stop detection relay 5 is energized.

Accordingly, the normally open contact 5b is closed and the normally closed contact 5a is opened. Therefore,
The function of opening the door from the front is disabled, and the power line L1 - normally open contact 5b - normally closed contact 7
A closed circuit of b-normally open contact 10-rear priority service detection relay 4-power line L2 is formed.

As a result, the rear priority service detection relay 4 is energized, and the front priority service detection relay 7 is prevented from being energized because the normally closed contact 5a of the wheelchair stop detection relay 5 is open.

After this, when the elevator arrives at the door zone on the second floor, the normally open contact 17 of the door zone detection relay,
22 is opened. Therefore, the normally closed contact 12b of the stop detection relay for the rear door is open due to the rear wheelchair call, so the energization condition is not satisfied and the door control relay 19 for the rear door is deenergized, and the rear door is opened. serve.

In this way, in the above embodiment, when a two-door, two-gate elevator is provided with dedicated operation such as wheelchair operation, priority service is given to the dedicated call, making the elevator very easy to use for both the dedicated call customers and general users. be able to.

In addition, in the above embodiment, the dedicated driving mode was explained as wheelchair driving by calling a wheelchair.
A similar effect can be obtained in executive-only operation.

Further, in the above embodiment, the door-opening priority service for general calls (landing or car) has been described as the front-side priority service, but the door-opening priority service can be implemented in either case, and the same effect can be obtained.

Further, in the above embodiment, the case where the wheelchair call is placed on the rear side has been described, but the same effect can be obtained even if the wheelchair call is placed on the front side or both sides.

Although the explanation has been given with priority given to stoppage detection through dedicated operation, it is also possible to easily switch the priority based on time or the like.

[Effect of idea]

As explained above, in this invention, a dedicated call stop detection means is provided, and when the dedicated call stop detection means is activated, the door opening priority service detection device is disabled and priority service is given from the dedicated call. The elevator can be made very easy to use for both customers and general customers.
