Description

DETAILED DESCRIPTION OF THE INVENTION Object of the Invention (Field of Industrial Application) The present invention relates to an elevator operating system.

(Prior Art) An elevator is controlled to always stop at a level within a certain range with respect to a floor surface of a landing of each floor during normal operation.

However, there is a case in which the car is stopped due to a large deviation from the floor surface of the landing, which exceeds the allowable range, due to expansion and contraction of the suspension rope caused by passengers getting on and off. When such a large landing error occurs, a step difference between the floor of the landing and the floor of the car causes troubles in getting on and off passengers and loading luggage.

Therefore, in the conventional elevator operation system, a landing error detection means is provided, and if a large landing error occurs in the car that exceeds the allowable range, the doors are fully closed and re-flooring is performed again, so that passengers can get on and off again. It is designed to allow passengers to get on and off and load luggage.

(Problems to be solved by the invention) However, in such a conventional elevator operation system, even if a passenger is calling a car or a waiting passenger at the landing is calling a floor, a landing error is generated. When it occurs, firstly, the passengers are re-fed, then the passengers get on and off the specified floor, the luggage is loaded, and then the procedure to move to the called floor is taken. There was a problem in that the driver had to wait a long time for re-adjustment, which deteriorated the driving effect.

The present invention has been made to solve such conventional problems, and an object thereof is to provide an elevator operation system capable of efficient operation without causing passengers or waiters to wait for a long time. To aim.

[Structure of the Invention] (Means for Solving the Problems) In the elevator operating system of the present invention, the elevator operating means and the car stopped with a large deviation from the permissible range with respect to a predetermined floor. Occasionally, a landing error detecting means for detecting a landing error of the car, and a re-floating means for causing the driving means to perform a re-floating operation when the landing error detecting means detects a car landing error of the car And a call detecting means for detecting a car call to a floor other than the predetermined floor or a floor call on a floor other than the predetermined floor, and this call detecting means detects the car call or the floor call. And a re-bed jumping means for causing the driving means to perform a normal operation.

(Operation) In the elevator operating system of the present invention, the landing error detecting means detects the landing error of the car when the elevator stops at a predetermined floor by the operating means. Then, if a large landing error has occurred exceeding the allowable range, re-flooring is performed by the signal from the landing error detection means. However, when a passenger pushes a car call button on another floor when stopping at a predetermined floor, or when a passenger waiting at a landing on another floor pushes the floor call button, the call detection means reactivates the call. The re-floating operation of the floor-matching means is jumped to perform a normal operation, and the floor is called up promptly to shorten the waiting time for passengers and waiting passengers.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows an embodiment of the present invention. This elevator operating system includes a driving means 2 for elevating and lowering a car 1 to a predetermined floor in response to a floor call of a passenger and a car call of a waiting passenger at a landing, and a car 1 for each floor 3-1. 3-
2, etc., the flooring error detecting means 4-1, 4-2, ... for checking whether or not the flooring has been accurately landed, and outputting a flooring error signal when the floor is greatly deviated from the permissible range, and each floor 3-1, 3-2,
Receiving error detection signals from the landing error detecting means 4-1, 4-2, ... Are provided with the re-floating means 5 for instructing the operating means 2 to perform a re-floating operation.

The elevator driving system further includes a call detecting means 6 for detecting that a passenger in the car 1 has pressed a car call button or a waiting passenger at the landing has pressed a floor call button.
And a re-floating jumping means 7 for jumping the re-floating command of the floor-floating means 5 in response to the call detection signal from the call detecting means 6.

Therefore, the driving means 2 usually has predetermined floors 3-1 and 3− in accordance with the car call signal of the passenger and the floor call signal of the waiting passenger.
Elevate to 2, ... and carry passengers and luggage.

The landing error detecting means 4-1, 4-2, ... Stop accurately within a predetermined level when the car 1 stops on each floor 3-1, 3-2 ,. Watch if you do.
Then, when a large landing error occurs beyond the allowable range, a landing error detection signal is given to the re-flooring unit 5.

The re-flooring means 5 receives the flooring error detection signal and gives a re-floating operation command to the driving means 2.

In response to this re-floating command signal, the driving means 2 causes the door of the car 1 on the floor that has been temporarily stopped, for example, the floor 3-1.
Fully close 8,8 and readjust the stop position of car 1, then reopen doors 8,8 to allow passengers to get on and off.

Here, when another passenger is in the car 1 and is calling a car on another floor 3-2, 3-3, ..., or another floor 3
When a passenger waiting at the landing of -2, 3-3, ... Is calling the floor, the call detecting means 6 detects the call signal and gives the re-positioning jump means 7 a detection signal. In response to the call signal, the re-floor jumping means 7 gives a re-floor jump signal to the driving means 2 and ignores the re-float command signal of the re-floor adjusting means 5 to perform normal operation. Order.

Thus, even if the landing error is within the allowable range, the driver corps 2 jumps the re-flooring operation and performs normal operation when the call signal is generated, thereby waiting for passengers and waiting passengers. It should be shortened.

2 and 3 show a more detailed structure of the above-mentioned embodiment, and FIG. 2 shows a part of the operating means 2, the re-floor adjusting means 5, the call detecting means 6 and the re-floating jumping means 7.
FIG. 3 shows the landing error detection means 4-1, 4-2, ....

As shown in FIG. 3, on each floor 3-1, 3-2, ..., a lower limit switch 9 for detecting that the car 1 has stopped beyond a predetermined range by being largely displaced downward, An upper limit switch 10 is provided for detecting that the vehicle has stopped beyond a predetermined range by being largely displaced upward.

As shown in FIG. 2, the normally open contact 9a of the lower limit switch 9 and the normally open contact 10 of the upper limit switch 10 are shown in FIG.
a and a are respectively connected to an operation command relay 11 for performing door closing re-floating in the ascending direction and an operation command relay 12 for performing door closing re-floating in the descending direction.

Both of the normally open contacts 9a, 10a are connected to a normally open contact 13a of a door close detection switch (not shown) for detecting the door close of the car 1. The normally open contact 13a of the door close detection switch has normally-closed contacts 14b and 15b of the ascending operation relay 14 and the descending operation relay 15 that perform normal operation, and passengers on the passenger floor 1 call the car, or A normally-closed contact 16b of a call detection relay (not shown) that detects that the waiting passenger is calling the floor is connected in series.

The ascending operation relay 14 and the descending operation relay 15 are connected to the other normally-open contact 13a of the door-close detection relay, and a normally-operated ascending auxiliary relay (not shown) for instructing a normal ascending operation is normally opened. The contact 17a and the normally open contact 18a of the descending operation auxiliary relay (not shown) are connected to these ascending operation relays 1
4, connected to the descending operation relay 15.

The other normally open contact 13 of the door close detection switch
A normally-closed contact 9b of the lower limit switch 9 and a normally-closed contact 10b of the upper limit switch 10 are connected in series to a.

And, in parallel with these normally closed contacts 9b, 10b, the normally open contact 14a of the ascending operation relay 14 and the normally open contact 15 of the descending operation relay 15
Further, a normally open contact 16a of a call detection relay (not shown) is connected.

The operation of the elevator operating system having the above configuration will be described below.

Normal operation On the normal operation route A side, when the car 1 stops at the normal level and the lower limit switch 9 and the upper limit switch 10 do not work, the normally closed contacts 9b, 10b are in the closed state. Further, since the doors 8 and 8 are closed, the door close detection continuator (not shown) is energized, and the normally open contact 13
a is also closed.

During normal operation, the ascending operation auxiliary relay or the descending operation auxiliary relay (not shown) is energized to give an operation command, so one of the normally open contacts 17a, 18a of these relays is closed. As a result, the ascending operation relay 14 or the descending operation relay 15 is energized, and the normal ascending operation or descending operation is performed.

Re-flooring operation When the car 1 stops at a predetermined floor, for example, floor 3-1 and if the landing error exceeds the allowable range, the lower limit switch 9 or the upper limit switch 10 is turned on. As a result, the normally closed contact 9 on the normal operation route A side
One of b and 10b is open and normal operation is prohibited.

On the other hand, when the lower limit switch 9 or the upper limit switch 10 is turned on, these normally open contacts are
One of 9a and 10a is closed. Therefore, when the door is closed, one of the operation command relays 11 and 12 for door closing and re-flooring of the re-flooring means 5 is energized, and a necessary re-floating operation is performed.

Re-floor jumping operation If the call detection relay (not shown) is energized by the call signal on the re-floating operation path B side, the normally closed contact 16b is opened and the re-floating operation is performed. The operation will be prohibited. On the other hand, on the side of the normal driving route A,
Even if the normally closed contact 16a of the call detection relay is closed by the call signal and the landing error is large and the lower limit switch 9 and the upper limit switch 10 operate to open these normally closed contacts 9b, 10b, The conduction state of the normal operation route A is maintained, and the normal operation is continued.

By the above operation, when a landing error exceeding the allowable range is detected, the re-flooring operation can be performed after the door is closed. When a passenger in the car 1 is calling the car or a waiting passenger at the landing is calling the floor, even if the landing error exceeds the allowable range,
The waiting time for passengers can be shortened by continuing the normal operation without performing the re-bed adjustment operation.

[Effects of the Invention] As described above, according to the present invention, the re-flooring operation can be performed when a large landing error exceeding the allowable range occurs in the car. When there is a call or a car call on another floor, the re-floating operation is jumped to perform the normal operation, so the time for the re-floating operation can be omitted, and the other floors can be omitted. The waiting time for passengers and waiting passengers on the floor can be shortened and driving efficiency can be improved.
