Description

[Detailed Description of the Invention] This invention relates to a device for displaying the operation of a car at an elevator landing.

In the elevator, a hall call is registered by operating a hall button installed at one hall.

Therefore, if the power to the hall button circuit is lost due to, for example, a fuse blowing out, hall calls cannot be registered and the car will no longer respond to hall calls.

In particular, in elevators where multiple cars are managed as a group, the above hall call is registered for each car, so
All cars stop responding to hall calls.

Furthermore, even if the hall button circuit and the circuits of each car are normal, if the group control circuits such as the first car selection circuit and the departure timer are out of order, all the cars will be unable to operate.

As a result, it causes a great deal of inconvenience to the passengers waiting at the landings on each floor.
Become.

Therefore, when such a failure occurs in the management circuit, all cars are stopped on all floors, or half of the cars in a group are stopped on odd-numbered floors and the other half on even-numbered floors. , reducing confusion within the building.

However, even with such special operation, the passengers waiting at the platform do not know anything and do not know which car they should use.

The purpose of this invention is to improve the above-mentioned problems, and to provide an elevator hall display device that notifies waiting passengers at the hall when the management circuit breaks down and clearly informs them of the car they should use. do.

An embodiment of this invention will be described below with reference to FIGS. 1 to 4.

In Figure 1, a - d are elevator cars, and cars a y
b and car ctd are arranged in parallel, and are arranged facing each other.

Reference numerals 1 and 1 designate landing buttons installed on the wall between the landings of cars a and b and on the wall between the landings of cars C and d.

In Figure 2, 1A is an up call button made of green transparent resin that is installed on the landing button 1 on the first floor, and 1D is an up call button that is built into the hall button 1 and lights up when it lights up.The up call button illuminates one person. It is a registered light.

There is a down call button made of red transparent resin on the top floor, and up call and down call buttons on the middle floors, but since this is well known, I will not explain it in detail. Omitted.

In Figures 3 and 4, →-2- is a DC power supply, Fl to F4
is a fuse, and IA to 9A are up-call buttons located at the landings on the 1st to 9th floors, respectively (down-call buttons are omitted)
, 1B to 9B are the up-call registration relays for the landings on the 1st to 9th floors, respectively, and IBa to 9Ba.

IBb~9Bb are their normally open contacts, ICa~9C, respectively.
A car position relay contact, ICb~, which opens when each car reaches a position where it can properly decelerate and land on the 1st to 9th floors.
9Cb is a car position relay contact that also closes, 1D~9
D is the 1L call registration light built into the up call button of the landing button on the 1st to 9th floor, 11 is the power detection relay of the hall button circuit, lla is its normally closed contact, and 12 is the previously mentioned first car. A failure detection relay contact that closes when a failure is detected in a group management circuit such as a selection circuit or a departure timer, 13 is a management circuit failure detection relay, 13a to 13j are normally open contacts thereof, 13 is also a normally closed contact, 14 is a stop command relay which issues a command to stop the car when energized. It is now assumed that the fuses F1 to F4 are normal.

The power supply detection relay 11 is energized σ, and the contact 11a is open.

If there is a failure in the group control circuit, attack fault detection m relay contact 12
Since is open, failure detection relay 13 is deenergized, contacts 13a to 13j are open, and contact 13 is closed.

Therefore, the seven call registration lights 1D to 9D are off.

The car is on the 1st floor, and when the 9th floor landing call button 9A is pressed, (→-Fl-13 9A-9Ca-98-
The up call registration relay 9B is energized by the circuit F2 () and self-maintains by closing the contact 9Ba.

At the same time, contact 9Bb is also closed, and registration light 9D lights up to indicate that the up call has been registered.

Activation of registration relay 9B causes the car to rise by a known elevator control circuit (not shown).

When the car approaches the 9th floor, the car position relay contact 9Ca is opened, the registration relay 9B is deenergized, and the contact 9Ba is opened, canceling the hall call registration.

At the same time, the contact 9Bb is also opened and the registration light 9D is turned off.

This is normal operation. The same goes for operation in response to a button or a call to get off the platform.

Meetings and baskets are on the 1st floor, F1. Assume that F2 is fused.

Since power to this circuit is lost, power detection relay 11 is deenergized and contact 11a is closed.

As a result, the failure detection relay 13 is energized, and the contact 13
a is closed.

When the car approaches the second floor, contact 2Cb closes and the stop command relay 14 is energized by the circuit of car F'3-2Cb-13a-14-F4 (), so the car stops on the second floor. do.

Thereafter, each time the contacts 3Cb to 9Cb are closed, the stop command relay 14 is energized, so the car stops at each floor in sequence.

At the same time, the contacts 13b to 13j are also closed, so the registration lights 1D to 9D on all floors are lit, indicating that an up call is registered on all floors.

This light was turned on when a hall call was registered, so it is clear that it will not go out when the car stops.

Note that even if fuses Fl and F2 are healthy, contact 12 will close if a failure occurs in the group management circuit.
The detection relay 13 is energized, and the same operation as described above is performed to stop each floor, and all the registration lights 1D to 9D are lit.

Further, it is not necessary to use the contact point 13k in FIG. 3 in this embodiment.

FIG. 5 shows another embodiment of this invention, which concerns a car atb.

In the diagram, IBc to 9Bc are uplink call registration relays 1B to 9B.
The other points are the same as those in FIGS. 1 to 3.

When the detection relay 13 is energized as described above, the contact 13
a is closed.

Every time car a and car b approach an odd-numbered floor, contact I
Cb, 3Cb, 5Cb, 7Cb and 9Cb are closed in sequence, the stop command relay 14 is energized -gn, and car a or car b stops at an odd-numbered floor.

At the same time, contacts 13b, 13d, and 13f. 13h and 13j will be closed, so the registered light IDs of odd-numbered floors, 3D, 5D, 7D
, 9D lights up to indicate that an up call is registered on an odd-numbered floor.

Also, registered lights 2D, 4D, 6D, and 8D on even-numbered floors.

10D is off, even numbered floor up call button 2A,
Even if I press 4A, 6A, 8A, and IOA, the up call is not registered and the registration lights are 2D and 4D.

6D, 8D, and 10D do not light up.

As a result, customers waiting on odd-numbered floors will use car a or car b.

Similarly, for cars C and d, the registration lights (not shown) on even-numbered floors are lit, and the registration lights (not shown) on odd-numbered floors are turned off.

As a result, waiting customers on even-numbered floors will use cars C and d.

In Tomuri's invention as explained above, when the management circuit fails, the car is automatically put into service on all floors or a specific floor, and the landing call registration lights on those floors are turned on, so the waiting area at the landing is turned on. Customers can be clearly informed of the basket they should use.
