Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an operating device when an elevator door fails.

In recent years, with the remarkable spread of elevators in high-rise apartment complexes and small and medium-sized buildings, accidents have occurred in which passengers are trapped in cars due to door failures.

As is well known, an elevator is provided with a door for each car and landing area, and when the car reaches a floor, the car door opens, and at the same time, the landing door opens.

However, at this time, the door threshold was clogged with trash,
If a malfunction occurs in the interlocking mechanism between the corner door and the landing door, the car will stop at that floor with the door closed.

As a result, the passengers are trapped inside the car and need to be rescued as soon as possible.

When multiple cars are installed in parallel, for example, A
When the above-mentioned malfunction occurs in the No. A car, it is conceivable that the A No. A car discontinues the destination call registration for the floor where the abnormality was detected, and the A No. 1 car no longer provides service to the abnormal floor.

However, if Unit A does not provide service to the 8th floor, for example, there will be offices and living rooms on the 8th floor, and for customers who use the elevator to go back and forth between the 8th floor and other floors, it will be temporary. You will be placed in an extremely inconvenient situation.

Therefore, of course you will need to use the B or C elevators that are installed side by side (if 3 cars are installed side by side), but on floors other than the 8th floor, the 3 cars will serve you equally.
For calls registered on the 8th floor, only two cars, B or C, will be serviced.

Moreover, in the management method that manages the operation of multiple cars, 8
Even if it is an A car that does not have driving service on the floor, if there is a car near the 8th floor (for example, the 7th or 9th floor), unless the call is in the opposite direction to the running direction of A car, the B or C car will be on the 8th floor. Normally, it is assumed that machine A will respond to the call registration and does not respond.

Therefore, the chances that the car will serve the calls on the 8th floor are decreasing, and the customers are forced to wait for a long time, which makes them feel extremely irritated.

This invention is intended to improve the above-mentioned problems, and aims to provide an elevator failure operating device that prevents the car service to the abnormal floor from deteriorating even if the car cannot move due to an abnormal door opening. .

Hereinafter, this invention will be explained with reference to Figures 1 to 4.
An example in which two machines of No. 1 are installed in parallel will be described.

This is an abnormality warning light installed on the floor.

Note that although the circuits in each figure are for the A machine, the same circuit is also provided for the B machine.

However, the contacts 13b and 14b connected by the broken lines in Figure 3
.

Only numbers 15b, 16b, 18b and INg to 9Ng are for B machine.

(When each figure shows the contact points for the B machine, these contacts are for the A machine.

) Next, the operation of this embodiment will be explained.

Now, consider a case where the car rises from the first floor and lands on the second floor.

While the car is running, the door opening/closing command relay 5 is (G)-6b-5.
It is held by the circuit a-5-(→, the contact 5b is closed, and the contact 5c is open.

Since the door abnormality detection time relay 1 is energized and the contact 1a is open, the door abnormality detection relay 2 is deenergized.

Simultaneously with the landing of the car, the contact 6b is opened, so the command relay 5 is deenergized, the contact 5b is opened, and the contact 5c is closed.

If the car floor is approximately 200 mm above and below the second floor floor, the door opening/closing area detection switch 10 is closed (Condolence-9105).
cm2e 4 3a - (Due to the → circuit, the door opening relay 4 is energized and the door begins to open.

At the same time, the contact 4b opens and the time limit relay 1 counts the time limit, but if the door is normal, the nine doors will finish opening before the time limit relay 1 returns, and the fully open detection switch 9 will open and the door opening relay 4 will open. The power is deenergized and the contact 4b is closed.

Therefore, the time relay 1 is energized again, the contact 1a remains open, and the door abnormality detection relay 2 is not energized.

Even if the door finishes opening and relay 4 is de-energized, it will continue for a certain period of time (
4 to 6 seconds), the door opening time control time limit relay contact 12a is open, so the command relay 5 is not energized and the door is held open.

Eventually, when the above-mentioned time limit passes and the contact 12a closes,
(I) -11-4cm12a -5-(The command relay 5 is energized by the → circuit, and the contact 5b is closed.

(-F)-8-5b-3-4a -(→ circuit,
The door closing relay 3 is energized and the door begins to close.

When the door is completely closed, the fully closed detection relay 8 is opened and the door closing relay 3 is deenergized.

When it is detected that both the car door and the landing door have been closed, the car departs in response to the next call.

However, even though the car has landed on the floor and the door-opening relay 4 has been energized, the door does not open completely due to dirt clogging the door sill or a malfunction in the door interlocking device mentioned above. Suppose that

By opening the contact 4b, the υ time relay 1 returns after a certain period of time, and the contact 1a closes.

(G) -6a-7a-1a -2 (The abnormality detection relay 2 is energized by the circuit shown in →, and is self-held by closing the contact 2a.

Moreover, since the door opening relay 4 is deenergized by opening the contact point 2e, the door opening operation is immediately stopped, and burnout of the door driving motor is prevented.

At the same time, contact 2b is closed. e+e 11-4cm2
b -5-(→) The command relay 5 is energized, so the door starts closing.

At the same time, contact 2c is closed. If the car position is currently on the second floor, car position switch 2Fb opens and switch IF
Since b is closed, (-1-)-2c -I Fb
-17b-15a-16H circuit activates the descending direction command relay 16 even if there is no other call registration, and when the door is completely closed, the car automatically starts descending operation.

However, if other passengers wishing to go to another floor board the train, and if there is a call for the destination of that floor, the train will respond to the call and depart.

When the car starts descending operation, descending operation relay contact 7a
is opened, so the detection relay 2 is deenergized.

Although the details are omitted, the car lands on the next floor (in this case, the first floor), and the door opens as usual on the floor where it landed, allowing the passengers inside the car to be safely rescued.

At this time, when an abnormality is detected in the door on the second floor, the detection relay contact 2d closes and the car position switch 2Fc closes, so (g) -17cm2d-2Fc-2N- (→ circuit) The abnormal floor detection relay 2N is energized, and the contact 2
Self-retained by closing Na.

Further, since the contact point 2Nb is closed, the abnormality alarm buzzer 2B on the second floor sounds and the abnormality warning light 2L lights up to notify of an abnormality in the door on the second floor.

If this is notified not only at the landing, but also inside the car, in the manager's room, etc., failures can be detected quickly and repairs can be completed quickly, so users are not forced to inconvenience themselves for a long time.

When a failure is detected, once the automatic operation is switched to manual operation for repair, the automatic operation relay contact 17c is opened and the detection relay 2N is deenergized and reset.

Next, let us assume that Car B is in the process of descending to near the 7th floor.

At this time, if the hall up call button is pressed on the 8th floor,
The 8th floor landing up call registration relay contacts 8Ua and 8Ub are closed.

Car position switch 7Fc of car B is open, so
(A) (→8Ua-8Nc-9Fa-13 (→) The upper hall call detection relay 13 of the B car is energized, and the contact 13b is closed.

However, since the B car is traveling in the downward direction, the downward direction command relay 16 is energized and the contact 16b is closed.

Therefore, (-1-)(→16b -13b-18-C
The response determination relay 18 of the A machine is energized by the circuit →, and the contact 18 is closed.

On the other hand, if the car in car A is on the 8th floor or below, then B
As in the case of the No. 1 car, the upper landing detection relay 13 is energized and the contact 13a is closed.

The car call for the 7th floor is registered in Car A, and if this is the last call, when Car A arrives at the 7th floor, the car call relay contact 7Ka (not shown) for the 7th floor will open and the car will descend. Direction command relay 16 is deenergized and contact 16a is closed.

Here, (+) 18a-13a-9Fb 17a
-16b-15-(→ The ascending direction command relay 15 of machine A is energized.

On the other hand, the response determination relay 18 of the B machine is connected to the contact 1 of the A machine.
4b.

Since 16b and 18b are open, it is deenergized,
Contact 18b is closed.

Therefore, the response determination relay 18 of machine A is (4)-1
8b-18-(→ is held in the circuit, and the upward direction command relay 15 is also held.

Therefore, when the 8th floor landing up call is registered, the B car does not respond to the 8th floor (because the B car's response determination relay 18 is not activated, and the B car's ascent direction command relay 15 is not activated.

), after Car No. A finishes responding to the final call, it reverses direction and operates up as mentioned above, and responds to the up call on the 8th floor landing.

This is a common landing call for each car, and when controlled operation is carried out,
This is an operation in which a call from behind the hall of the other car (a call in the opposite direction to the driving direction) is detected, and the own car responds to the call from behind.

Now, suppose that a door abnormality Z occurs in Unit A on the 8th floor.
Even if Unit A answered the call from the 8th floor, the door would not open, so
Customers waiting on the floor cannot use the elevator.

Also, as long as No. A is stopped on the 8th floor, you will not be able to register for a landing call on the 8th floor, and No. B will not respond.
This will become even more inconvenient for the customers waiting on the 8th floor.

However, when a door abnormality occurs on the 8th floor of Unit A, the abnormal floor detection relay 8N (not shown) on the 8th floor is energized, and the contact 8N
e, 8Nf is open.

Therefore, even if a car call on the 8th floor is registered, contact 8K
a.

Even if 8Kb is closed, the direction of operation will not be determined, and Unit A will no longer travel to the 8th floor.

At this time, a passenger who wants to go to the malfunctioning floor, the 8th floor, from another floor
When I boarded the aircraft, I was unable to land on the 8th floor and there was a problem, so I
It is desirable to configure the car so that the call cannot be registered even if a display indicating that the 8th floor is out of order or the faulty floor destination button in the car is pressed. It is better to configure it so that it is not biased.

1. Since the contacts 8Nc and 8Nd are also opened, even if the landing call registration relay contact 8Ua is closed, the detection relay 13
．． 14 is not energized and command relays 15, 16 are not energized.

As a result, even if the landing button on the 8th floor is pressed, Car A does not respond.

On the other hand, when the 8th floor landing call button is pressed, registered relay contact 8Ub is closed.

Contact 8Ng of Unit A is closed, so (a) -8N
g-8Ub18 <→ The response determination relay 18 of the B machine is energized, and the contact 18a is closed.

Contact 8Nc of Unit B is closed, so when contact 8Ua is closed, +(→8Ua-8Nc-9Fc-13-(→
The detection relay 13 is energized by the circuit.

Contact 13a is closed.

The command relay 15 is now energized, and after the B car responds to the final call, it reverses direction and operates upward, responding to the call on the 8th floor.

As a result, passengers on the 8th floor will be able to use Car B, which is not out of order.

Although the above embodiment describes an elevator that manages and operates two cars, it can be similarly applied to a case where there are three or more cars.

Furthermore, even if a plurality of independent elevators that are not operated under management are installed in parallel, it is clear that this can be similarly implemented by transferring the hall call registration for the abnormal floor of the abnormal elevator to another healthy elevator.

As explained above, in this invention, when the door does not open even when a car arrives at a floor, other healthy cars are made to respond to the call on the abnormal floor, so that the customers waiting on the abnormal floor are A car can be used, and service degradation on abnormal floors can be prevented.
