Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to an operation device for stopping each floor of an elevator, which automatically stops at each floor until the car reaches the destination floor by calling a car or not and operating a button switch. .

[Technical background of the invention and its problems]

The inside of an elevator car is a closed room, and crimes committed inside the car are unavoidable. In order to prevent such crimes, the Building Standards Act (Article 129-9-13, Elevator Safety Devices) stipulates that in passenger elevators, the car must stop at each entrance to each floor, and the doors automatically open. It is mandatory to have equipment that can do this. For this reason, a stop switch for each floor is provided in the car operation panel, and when a passenger in the car operates the call button with each floor stop switch closed, the car will stop at each floor in sequence until it reaches the destination floor. It is designed to be driven while driving.

However, the stop switch on each floor is the Elevator Association standard (No. 4
Article 02, Paragraph 2) stipulates that the car operation panel be stored in a locked box, and therefore, each floor stop switch cannot be easily operated by anyone other than the elevator manager, for example. In addition, the stop switch for each floor is a lock type switch, so once it is operated, the stop operation for each floor continues regardless of the passenger's will until it is reset, resulting in poor operating efficiency and inconvenience in high-rise residential buildings. .

Furthermore, each floor stop switch must be operated by, for example, an elevator manager, which is cumbersome, and if for some reason the floor stop switch is not operated frequently, this poses a crime prevention problem.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide an elevator that can stop each floor only when required by passengers in the car, improves operating efficiency, and is advantageous in terms of crime prevention.

[Summary of the invention]

The present invention provides an elevator in which a car can be stopped at each floor by operating a hall call button switch or a side call button switch for each floor. The condition is that the car is switched to an operation in which the car stops at each floor sequentially until it reaches the destination floor, regardless of the operation of the hall call button switch.

42-2b is a contact point of a relay 42 (not shown) which is closed when the car is in upward operation and held until the car stops. 22-, i! A is one contact of the above-mentioned tail call registration relay 22 shown in FIG.

In addition, 33-2a is the relay 33 that detects that the call button has been operated twice and commands the stop operation of each floor.
This is the point of contact.

40 is a deceleration command relay that issues a deceleration command to land on a stop floor. 43 is a call cancellation relay that cancels the call of the car at the same time as it lands on the destination floor.
It consists of C and A contacts 43-1h. Reference numeral 44 denotes a canceling transformer, which cancels the DC signal by inputting the AC signal to the DC circuit. 45 is a Zener diode.

Hereinafter, the operation of the floor stopping device of the present invention configured as described above will be explained. Assume that the car is stopped on the first floor and the call button P3K for the third floor is pressed twice.

Turn on the car call When P3K is operated for the first time, car call relay 2 is activated by = JH-2IC-N to P-P3 in Figure 1.
The first coil 21C is excited. Also -20 to P-P3
A car call signal is input by 0-[phase]-3KR-N, and P

When 0C is excited, the limit timer 30 starts counting.

The contacts 31-1& are closed by the excitation of the coil 31C, and a self-holding circuit is formed by P-31-1a-30-1b-31C-N.

Then, operate the call button P3 for the first time (Fig. 4-
Did you call for the second time within 3 seconds after the point shown in A)? When the button PJK is operated (time B shown in FIG. 5), the second call data 10-P3 operation is controlled by the above-mentioned key call limit timer 30, which is currently set to 3 seconds. Then, did you call me the first time? If the button P3K is not operated a second time within 3 seconds after it is operated, it will become invalid.

In Figure 2, P -21-1a -30C-N and P
-31-1a-30-1b-3I C-N continues to hold, but contact 3O- of the limit timer 30
1b is opened after 3 seconds, the coil 30C and coil 31C of the car call limit timer 30 are demagnetized, and the contact 3l-
1a.

3l-2a is opened. Also, the second call to the button P3 will not take effect unless the first operation returns.
When the button is held down, it is treated as one operation.

When the first operation of car call button P3 is completed, car call relay 2 is released, and as shown in FIG. 2, contact 2l-2b of car call relay 21 returns to P-21-2b.
-31-2a-32C-N excites the coil 32C of the car call relay 32, its contacts 32-1 & close, and a holding circuit is formed for P-32-1 by -31-2a -32C-H. .

If the car call button P3K is operated for the second time within 3 seconds of the activation of the corner call limit timer 30, the

The coil 40C of the deceleration command relay 40 is energized by H, and the vehicle begins to decelerate to stop on the second floor. At the same time as this landing, a door (not shown) opens due to the running open.
After a certain door opening time, the door closes. The call for the third floor is still registered, and when the door closes, the car departs and heads for the third floor. When the third floor deceleration command point is reached, the movable plan 2UB comes into contact with the selector stator 3YL, which was pressurized by the third floor heel call in FIG. −@− [phase] −

is opened, each floor stop relay 33 is released, and each floor stop operation is reset.

Is it called as mentioned above? Depending on the number of times the button P3 is operated, it is possible to select whether the car should be stopped at each floor, and it can also be automatically reset when the car reaches the destination floor. Therefore, each floor can be stopped only when required by the passengers in the car, and there is no need to operate each floor stop switch on the car operation panel, which improves operating efficiency and is advantageous in terms of crime prevention.

Note that the present invention is not limited to the embodiments described above, and can be implemented with the following modifications.

(1) By electrically connecting each floor stop switch 34 provided on the car operation panel 14 to the each floor stop operation operation circuit shown in Fig. 2 as shown by the broken line in the diagram, it is possible to use the car according to the purpose. .

(2) Operate the stop switch for each floor provided on the car operation panel. If you press the call button once within a certain period of time during stop operation on each floor, the stop operation for each floor will continue as it is, and if you press it twice, the stop operation for each floor will continue. It can also be reset. Specifically, the a contact 33-2a in FIG. 3 may be removed and the b contact 33-3b may be connected to this portion as shown by the broken line in the figure.

(3) The fact that the train has been switched to stop operation on each floor by operating the call button may be displayed at each floor landing using a known display means such as a visual display or an auditory display.

(4) It goes without saying that both the car call 4r button switch and the hall call button switch may be other switches that do not have a push button, such as a touch switch.

〔Effect of the invention〕

As explained above, according to the present invention, it is possible to switch to stop operation for each floor on the condition that the call button in the car is pressed at least once within a certain period of time, and a stop switch for each floor is provided on the corner operation panel. The need for elevators to stop at each floor can be selected by pressing a button between normal operation and operation that stops at each floor.Compared to the conventional operation where elevators stop at each floor, operation efficiency is improved and crime prevention is improved. Driving equipment can be provided.
