Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention provides an elevator that, upon detecting the inability to open a door, does not cancel the call when it decides to stop at a hall call in an elevator traveling toward the next called floor. This invention relates to an elevator operating device that cancels the call after the door is opened.

[Prior art]

Conventionally, when an elevator stops in response to a call, the door cannot be opened due to a malfunction in the door on that floor. At this time, the car cannot move on that floor and is no longer operable, causing great inconvenience to the passengers inside the car and the passengers waiting at the landing. To improve this, when you stop at the called floor,
A certain period of time (an analogy is JP-A-5J-107050)
It is proposed in the publication.

On the other hand, a normal hall call is canceled as soon as the car decides to stop at that floor (there is also a method of canceling the call just before the car stops).

This is because if cancellation of a hall call is delayed, other cars may decide to stop in response to that call, degrading the overall elevator service.

When the door cannot be opened as described above, if you are running towards another called floor and there is a landing call, it will decide to stop and cancel the call, so if the door is on the 7th floor, If it does not open, passengers waiting at that landing will have to register their call again.

Further, until the car detects that the door cannot be opened and the car leaves for another floor, the landing call cannot be registered, so passengers waiting at the landing are forced to wait for a long time.

[Summary of the invention]

This invention was made in order to eliminate the above-mentioned drawbacks of the conventional technology, and even if it is detected that the door cannot be opened and the driver decides to stop at a landing call while driving toward a call on another floor, the call will not be cancelled. To provide an elevator operating device which can cancel the call after the door is opened at a certain time so as not to inconvenience passengers in the hall.

Next, the operation of the elevator operating system of the present invention configured as described above will be explained. Now, when the door opens on the first floor, the top row button 2UB to land on the second floor.

Assume that the third floor landing button 3DB is pressed.

As a result, power line Ll-3rd floor landing button 3ρB
- Normally closed contact 3CD of relay 3CD canceled by 3rd floor landing descending call
A-3rd floor landing descending call relay 3D--a closed circuit of the power line L2 is formed, and this third floor landing descending call relay 3D is energized.

In addition, the normally closed contact 2CUa of power line LL - 2nd floor landing up call button 20B - 2nd floor landing up call canceling relay 2CU - 2nd floor landing up call relay 2U - power line L2 close circuit allows this 2nd floor landing up call relay 2U is energized.

As the 3rd floor landing descending call relay 3D is signaled,
The normally open contact 3Db is closed, and the normally open contact 2Ub of the second floor hall call relay 2U is also closed.

Both normally open contacts 3Db and 2Ub are closed 9, power line Ll - normally open contacts 3Db and 2Ub - connection point P3 - normally closed contact 3Fb - connection point P "normally closed contact 3Fa - upward direction command relay 4 - power supply A closed circuit of the lier L2 is formed.Therefore, this ascending direction command relay 4 is energized.

Here, when the door is fully closed, the door opening completion detection switch 16
a opens. This deenergizes the door opening relay 18 and opens its normally open contact 18b.

Accordingly, the door-opening setting time relay 13 starts counting from the time when the door-opening is completed and is deenergized 5 seconds later.

As a result, the normally open contact 13 of the door open time setting time relay 13
a is opened, and the door open setting relay 12 is deenergized. Furthermore, if the door opening button 11 is pressed even before this 5 seconds, the door opening time setting relay 12 is similarly deenergized.

By deenergizing this door opening time setting relay 12,
Its normally closed contact 12c is closed. As a result, the power line Ll-safety edge 6-door open button 7-normally closed contact 12
c-door control relay 9-' A closed circuit of the power line L2 is formed.

Therefore, the door control relay 9 is activated and its normally open contact 9b is closed. By closing this normally open contact 9b, a closed circuit of power line Ll - normally open contact 9b - door closed child completion detection switch 14 - door close relay 15 -' power line L2 is formed, and door close relay = 15 is energized. When this door closing relay 15 is activated, the door is closed.

In addition, the normally open contact 9 is used to energize the door control relay 9.
a is also closed. At this time, as the upward direction command relay 4 is already energized, its normally open contact 4a is also closed.

Therefore, a closed circuit of power line/Ll - normally open contact 9a - normally open contact 4a - run command relay 10 - power line L2 is formed, and as a result, when the door is completely closed, the car is raised by a circuit not shown. drive to.

As the car ascends, it takes one step to reach the second floor, and a circuit (not shown) issues a stop command to the car. As a result, the normally open contact 19 of the stop decision relay is closed.

By closing this normally open contact 19, the sealed contact 22b of the power line Ll-hall call cancellation prevention relay 22-
Normally open contact 19 - Connection point P8 - Intersection contact 4b of upward direction command relay 4 - Normally open contact 2FC-2 of second floor car position relay
A closed circuit between relay 2CU and power supply line L2 is formed to cancel the call for floor climbing.

Therefore, this second floor landing up call canceling relay 2CU is energized, and its normally open contact 2CUa is opened. By opening this normally open contact 2CUa, the second floor landing up call relay 2U is deenergized, and the car stops at the second floor.

When the car stops on the second floor, the normally open contact 8a of the running relay opens. Therefore, the door pipe auxiliary relay 9 is deenergized. This closes the normally closed contact 9C.

By closing this normally closed contact 9c, the power line L1 - normally closed contact 9C - door open completion detection switch 16a - normally open contact 17 of the door zone detection relay - normally closed contact 8d of the traveling relay - door open IJL/ -18=A closed circuit of power line L2 is formed. Accordingly, the door opening relay 18 is energized, and the door motor (not shown) is rotated to open 5f11, thereby opening the door.

However, if the door does not open for some reason, 5.
After seconds have elapsed, the door opening failure detection time relay 20 is deenergized.
Its normally closed contact 20a is closed.

By closing this normally closed contact 20a, power line Ll - normally closed contact 20a - normally closed contact 8e of the running relay
A closed circuit between door-unability detection relay 21 and power supply line L2 is formed. As a result, this door-openability detection relay 21 is activated.

By energizing the door opening failure detection relay 21, its normally open contact 2
1b is closed. As a result, a closed circuit of power line Ll - safety switch 6 - door open button 7 - normally open contact 21b - door control relay 9 - 11 source line L2 is formed, and this door control relay 9 is energized and the next call is made. The vehicle ascends toward the third floor, that is, the third floor.

At this point, by closing the normally open contact 21c of the door opening failure detection relay 21, the power supply line Ll-door opening completion detection switch 1 is closed.
6b - Normally open contact 21e - Hall call 1 extinguishing relay 22 -
A closed circuit of the power line L2 is formed, and its normally open contact 22
a is closed, and the hall call cancellation prevention relay 22 is self-held.

Further, as described above, when the vehicle starts traveling in the upward direction toward the third floor, the normally closed contact 8e of the travel relay opens, and the door-openability detection relay 21 is deenergized.

Next, when the car reaches the third floor, it is detected that the car has stopped, and the normally open contact 19 of the stop determination relay is closed, but at this time, as mentioned above, the hall call cancellation prevention relay 22 is already energized. The normally closed contact 22b is open.

Therefore, the 3rd floor landing down call cancellation relay 3CD is not energized, and the 3rd floor landing down call is not canceled.

Then, when you open the door on the third floor, the door opening completion detection switch 1
6b opens.

As a result, the hall call cancellation prevention relay 22 is deenergized, and its normally closed contact 22b is closed. Accordingly, power line Ll - normally closed contact 22b - normally closed contact 9d of door control relay 9 - connection point P8 - normally open contact 5b of descending direction command relay 5 - normally open contact 3FC of car position relay on the 3rd floor - 3rd floor A closed circuit of the hall descending call canceling relay 3CD and the power supply line L2 is formed.

Therefore, this 3rd floor landing call canceling relay 3CD is energized and cancels the 3rd floor descending call.

If the door does not open, the vehicle will move to the next called floor after 5 seconds in the same way as above.

FIG. 4 is a circuit diagram of another embodiment of the present invention, showing the periphery of a portion different from the circuit configuration of FIGS. 1 and 2, and the portion indicated by broken lines 100°200 This is a new addition to the circuit shown in FIG.

That is, as shown by the broken line 100, the hall call cancellation prevention relay 2 is connected in parallel to the normally open contact IC of the car call relay on the first floor.
Two normally open contacts 22c are connected.

Break again? As shown by l5200, a hall call cancellation signal is connected between the run command relay lO shown in FIG. Normally closed contact 22 of blocking relay 22
A parallel circuit between d and the normally open contact IFd of the first floor car position relay is connected.

By doing this, when it is detected that the door cannot be opened, the vehicle is returned to the lowest floor while responding to a call, and the vehicle is rendered inoperable on the lowest floor.

1. In the above embodiment, the cancellation of the call is performed after the door is fully opened, but it may be canceled when the door is about half open.

〔Effect of the invention〕

As described above, the elevator operating device t! of the present invention! t
According to VC, even if you decide to stop when the door is called to a landing while driving towards a call on another floor when the door cannot be opened, the door will open at least halfway and the call will be cancelled. (No longer waiting, and no more inconvenience to passengers at the boarding point.)
