Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a system for forcibly stopping an elevator for each floor.

[Prior art]

When the elevator car door closes, it becomes a closed room, and many crimes are taking advantage of this to assault passengers (particularly women). In order to rescue passengers from such crimes, passenger elevators are required to be equipped with a forced stop device on each floor. This is, for example,
-As shown in Publication No. 37956, it operates at a specific time at night, and stops at each floor with entrances and exits in sequence, regardless of the passenger's will, and repeatedly opens and closes the door until the passenger reaches the floor he or she wants to go to. This means that you have to drive while doing so.

In other words, the door is opened on each floor to give passengers in the car as many opportunities as possible to escape from the criminal.○
.

However, this forced stop operation for each floor will not be canceled until a specific time in the morning is reached, so even if a crime is unlikely to occur, such as when a person is riding the elevator at night or with an acquaintance, each floor will be shut down. Elevator service will be significantly worse than during the day, resulting in unnecessary stops. In addition, since the car repeatedly runs and stops, the frequency of starting the electric motor increases and the power consumption also increases. Then, the forced stop operation for each floor is canceled, and when the car arrives at the destination floor, the above-mentioned rear call is canceled.If necessary, the forced stop operation for each floor can be canceled with a simple operation, and the car can quickly reach the desired floor. To provide an operating device for an elevator, which allows the user to move the elevator to other places without causing wasteful operation.

(IG) to (4G) are car position contacts that close when the car is on the 1st to 4th floors, and (6) is a normally open contact for a 24-hour clock that closes at a specific time at night (for example, 10 p.m.). (7) is a night detection contact that closes when the time comes and opens at a specific time in the morning (for example, 6 a.m.), and (7) is a forced stop operation command relay for each floor that instructs the car to force a stop operation on each floor when energized.

In the detection relay, (10a) is its normally closed contact, (10b) and (loc) are also normally open contacts, αυ is the rear car call release condition detection relay, and (11a) to (11
f) is its normally open contact.

Next, the operation of this embodiment will be explained.

During normal hours, the night detection contact (6) is open, and the forced stop operation command relay (7) for each floor is deenergized, so the car operates normally.

In other words, when a passenger gets into a car on the 1st floor and presses the destination button (4A) on the 4th floor, (+) - (4A) - (
4C)-(11a)-(4B)-(-) circuit, 4
The floor heel call registration relay (4B) is energized and the contact (4B) is energized.
It maintains itself by closing Ba). The call for the car on the fourth floor is now registered, and a well-known elevator control circuit (not shown) is activated to cause the car to run up. When the car reaches the 4th floor, the 4th floor car position contact (4C) is opened, the 4th floor car call registration relay (4B) is deenergized, and the car call is released. The above is a normal operation. Now, assuming that it is a specific time period at night, the night detection contact (6) is closed.

Passengers board the car on the first floor and press the destination button on the fourth floor (
When 4A) is pressed, the fourth floor foot call registration relay (4B) is energized as described above, and self-holds by closing the contact (4Ba). Also, contacts (4Bb) to (aBf) are closed, and contacts (4B11!;) to (4Bj) are open.
Now, (+) −(4Bb) −(6) −(10a
) - (7) - (-) circuit energizes the forced stop operation command relay (7) for each floor, so the car starts up-bound operation, and up-direction relay contacts (8a) and (8b) are closed. If the passenger feels that there is no need for crime prevention operation, and the car starts running from the first floor, the car stops on the second and third floors, which are intermediate floors, to perform crime prevention operation. When you press the destination button (1 person), (+) - (IA) - (IC) - (11a) - (I

In this way, a car call on a floor located in the opposite direction (in this case, downward) from the car's traveling direction (in this case, upward) is called a rear call. At this time, if the car is moving to the second floor, the car position contact (2D) on the second floor is closed, so (+)-DBf)-(2D)"(sa)-(11

is closed. By opening the contact (1OA), the forced operation command relay (7) for each floor is deenergized, so the stop operation for each floor is canceled and the operation goes straight to the 4th floor, which is the passenger's destination floor. do) do.

When the car reaches the fourth floor, the car position contact (4G) closes. At this time, there is no call registered on the 5th floor and the contact (5Fg) is closed, so (+) - (5F

By opening the contact (lla), the first floor call release condition detection relay Qll is activated. ) is deenergized and the rear call is canceled.By opening the contact (11d), the fourth floor rear call registration relay (4B) is deenergized and the fourth floor rear call is also released.

Furthermore, by opening the contact point (11f), the rear call detection relay (1) is also deenergized.In this way, when the vehicle arrives at the destination floor, the rear call is automatically released.
After canceling the forced stop operation on each floor, there will be no unnecessary driving such as responding to calls from behind. In the example, the command for crime prevention driving is issued by the contact point (6) of the 24-hour clock, but This may be issued by a switch provided in the manager's room.

The same applies to the case of downhill travel, which can be easily explained.

〔Effect of the invention〕

As described above, in this invention, the elevator car is forced to stop at each floor based on the crime prevention operation command, and the elevator car is forced to stop at each floor. Once registered, the forced stop operation for each floor is canceled and the car runs to the destination floor, and when the car arrives at the destination floor, the above-mentioned rear call is canceled, so when crime prevention operation is not required, each floor can be stopped with a simple insertion. It is possible to cancel the forced stop operation and quickly go to the desired floor. Furthermore, it is possible to prevent wasteful operation caused by canceling the forced stop operation of each floor.
