Description

[Detailed Description of the Invention] Jin's invention relates to an elevator control device, and includes a TC device that opens the door and allows guests to escape when the elevator malfunctions.
*This is related to *.

Conventionally, elevators have been equipped with billions of security measures to ensure that even if they break down, they do not cause serious problems. Once activated, such safety measures rarely bring the elevator to a sudden stop and prevent it from proceeding to the first operation.

The conventional elevator control system will be explained based on Fig. 1. In Fig. 1, the mountain is driven by the electric motor (3) via the hoisting ae +2) to raise and lower the threshold between the first floor (41 and the shield (4+)). (5) is the driving circuit that energizes the t-motor t31 t-, (5a) is the stop signal issued from the 2!! turn (b) road (5) when the electric a!+3) is de-energized, (6

The door opening circuit that surrounds the elevator door, which was built and closed, (8) is the work of this door-circuit (7)! After @, the door opening timer f, which continues to open the door for a fixed period of time, +9), closes 5X when the timer of this door opening timer (8) ends, and the door closes the door, <92) is the door closing light 71 emitted when the door is closed by this door closing circuit (9)
At this point, the operating circuit (5) is closed.

In the above f#f elevator control device.

When the driving circuit (5) is closed, the electric motor (3) operates and the mountain moves up and down.

When the basket pile is @ layered on the 1j piece (4) of the building, the driving times 'Mt
(5) is released and stops. When the door circuit (7) is closed by this stop signal (5a), the door is enclosed. Passengers board and alight from the heel (2) while the door is closed by the door opening timer (8). *When God ends.

Door opening timer f: When the timer of 181 ends, the door is closed by the 1 door closing circuit i9J, and the 1 door closing light 71 (9aJ is input to the operating circuit (5). This input signal causes 2!

The IIh operation is repeated in the order of 9)→operating circuit (5).

By the way, when the above-mentioned circuit device fails, the operation stops at the point where the failure occurs, and subsequent operations cannot be continued. 41
When the operation circuit (5) breaks down and the car is closed, 9 doors are closed and the door close signal (9a) is issued, and the car is +1
1 does not start and remains stopped on the first floor (4). As a result, the nine passengers had the disadvantage of being trapped inside the cage for a long time until they were rescued.

This invention is intended to improve the above-mentioned drawbacks, and the two doors are closed.
The purpose of this system is to prevent passengers from becoming trapped in the car by opening one door when the car is forced to move up or down within a predetermined time after c.

FIGS. 2 and 3 show an embodiment of the present invention.

First, in Figure 2, 1ull is the entrance to the Kago rice field.

αΔ opens and closes this doorway uiI/'', ott is a door open detection means that is fixed to the top of the car pile and operates when one door finishes opening, and α1 is a door that is similarly fixed and operates when one door finishes closing. The door zone detection means (161), which is also fixed to the car pile, is fixed to the hoistway aη and is located within a predetermined range above and below the second floor (4).
One end of the cam that activates the door zone detection means, mark A, is connected to the car tlJK, and on the way, it is wrapped around the opening machine (2), and the other end is delayed to the end of the car. ,G

A door opening command means that operates when the brake switch [with] does not operate even after a predetermined time has elapsed, (44!J is a normally closed contact for time-limited operation, (44h), (44c)
Both are notification devices consisting of time-limited normally open contacts and a voice synthesizer.

The operation of controlling the elevator constructed as described above will now be described.

Assume that the cage pile is currently in the upward movement. Outward contactor 1

(c) is also closed), which also energizes the motor (3).0--(→) is energized by the circuit 0--(→), and its normally open connection (4) is closed and the door is closed. This is to close the delivery circuit (9) and keep the 0 door open closed.The 9 door opening timer device 1B
)'s normally closed contacts (8a) and (8bJ) are both open.

Next, when the car (υ) approaches the target floor (4), the door zone detection means is activated and its normally closed contact (15a) is opened. 1 Is the landing circuit opening activated and the same contact from the outside? ! ! (transfer) trRm. As a result, the electric 17Ib machine +31 and the electromagnet @ are both mlI, and the basket pile stops and one stock is shocked. The door control relay is activated by releasing the normally open contact (42d),
Its normally open contact (40d) is released to open the door closing circuit (7), and its normally closed contact (40eJ) is closed to open the door opening circuit (7).
) is closed. As a result, the door (2) opens, the second door closing detection means (141) returns, and the ninth door closing detection means 0 is activated.

When the door (2) finishes opening and 8 minutes have elapsed for the predetermined #, the 1 door open @ contact (8* (sbJ) is closed. This causes the 1 door control relay to change to (+) - (8a) - <44

When the normally open contact (40 dJ) closes, the door closing circuit (9
) is closed and one house (121 is closed. Upper F1 #14
If 1 is still called and the upper run command contact (31) is closed, the run command relay (rotation) is (→-
(31a) −(40bJ −(8b) −f411−
It is energized by the T → circuit.

Its normally open contact (41a) is closed. When the door is completely closed and the door closed detection means (normally open contact (141) of 14+) is closed, the door open command means - (→-(41aJ -(23)
a no (14bJ-(1s Lee-1-) is energized by the published circuit.However, the normally closed contact (44bJ , (
Before 44cJ operates, the ascending contactor (

a is added IIJ. As a result, the single-movement brake is operated, the brake switch is operated upward, and the 9-door opening command means is activated, and the corner peak is continuously raised.

The case of descending operation is also similar to the above, and theory #U is omitted.

By the way, let's say that Kadoyama arrives at # (41) and opens door A2. Meanwhile, there is a call on the upper floor (4).
It is assumed that the upward operation command contact (3 circles) is closed. When a predetermined period of time has elapsed, the above-mentioned door is closed and the door open command means (■) is energized. At this time, the contact between the upward direction contactor If the coil is l1yd, it will not operate, so its normally open contact (42a) will not be closed and the electromagnet 1 will not be energized.For this reason, the normally closed contact (42a) of the brake switch (to) will not be activated.

is (−1−(41a) −(23aJ−(14b) −
(15bJ-747) - (continues to be energized by the → circuit.

When a predetermined period of time has elapsed, the normally open contact (44b) closes at 1 o'clock and the door opening command means self-holds. , - 10,000, the normally closed contact (44a) is opened and the door control relay r-1 is energized.

The normally closed contact (40C) closes the door opening circuit (7) and opens the door a2. When the door a2 finishes opening, the normally open contact (1aa) of the door open detection means uJ is closed.

Speech synthesis device 4 (+) - (44eJ - (13a)
-(451-H) is energized and broadcasts the message ``This is a malfunction, so please get out of the car.''

Once the old camphor tree has been repaired, the push button switch (to) is operated to deenergize the single door opening command means +441. As a result, the normally closed contact (44aJ) is closed and the 9 door control 9 relays are closed.
is energized, one door αa is closed, and operation continues.

According to the above implementation sequence, after door 1 a2 is closed, if the brake switch Q does not operate even after the Pfr fixed time has elapsed, the 9 door open command hand JR- fully operates and the door (121 is opened). Therefore, the nine passengers will not be trapped (1)K.In addition, since the voice synthesizer 1451 was created and IdJ was created, it would be possible to inform the M operator that the first passenger was out of order.

In the above embodiment, the brake switch a1 is used as the activation detection means, but the #L brake 3) may be used to detect the output of the rotating needle.

In addition, in the above embodiment, it is assumed that the door Q3ri is opened and closed automatically, but even if the door Q3ri is opened and closed manually by nine people, when the door opening command means is activated, the message "Please open the door manually. ”, it functions in the same way as the above embodiment.

Yet again. The above actual mH is constructed by hoisting machine (2).
Although the explanation has been made regarding an elevator that is operated by a rotor, the present invention can also be applied to a hydraulic elevator.

In this invention, when the door closing detection means for detecting that the 9th car is closed is activated and the starting detection means for detecting the movement of the car is not activated within a predetermined period of time, the 9th door is closed. The command to open the door was issued by activating the opening command means.

This has the effect of completely preventing passengers from being trapped in the car.
