JPH0631133B2 - Arrival light for group management elevator - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to an arrival guide light for an elevator that performs group management.

[Conventional technology]

A group management elevator generally uses an arrival guide light instead of a position display light in order to efficiently operate a car as disclosed in Japanese Patent Publication No. 53-22333, and therefore, for passengers. Does not know which floor the car is running on or which floor the car is at.

Now, when a passenger pushes a hall button on a certain floor, an arrival guide light of the elevator corresponding to the call is turned on, and the car usually arrives after about 20 seconds have passed.

[Problems to be solved by the invention]

The conventional group management elevator configured as described above is stopped at any floor because the car is thrown out at the time of a quiet time, and when the passenger presses the landing button on this drop-off floor,
Since the car door opens immediately and closes after the standard time, there is a problem that the door closes before a passenger at a remote place gets into the car.

An object of the present invention is to provide a guide light for a group control elevator that allows passengers to reliably get on a car on a drop-off floor.

[Means for solving problems]

According to the present invention, a relay device, a resistance, and each of an ascending light and an alighting light of an arrival guide light are connected in series between DC power supplies, and the relay device is stopped at the floor while the car is in the dumping state. It is characterized in that it has a contact point that closes the series circuit when it is on.

[Work]

Since the present invention has the above-described configuration, when the car is in a state of being left in the car and is stopped on that floor, the rising light and the descending light of the arrival guide light are connected between the power supplies via the resistor. From this, it is possible to notify the passenger in a dim state as compared with the case of a normal arrival guide light.

〔Example〕

 Embodiments of the present invention will be described below with reference to the drawings.

FIG. 2 shows an entire hall on an arbitrary floor, for example, the third floor, in a group control elevator having four group control elevators.

The elevator doors A to D of Units 1 to 4 are juxtaposed as illustrated. Arrival light 1a and exit light 1b are provided above the landing door A of Unit 1, and similarly, rising lights 2a and 2a are also provided above the landing doors B, C and D of each unit.
3a, 4a and alighting lights 2b, 3b, 4b are provided. On the wall between the elevators of Units 1 to 4, call buttons common to all Units, that is, climbing buttons 1c and 2c.
And the descending buttons 1d and 2d are provided.

FIG. 1 shows an electric circuit diagram of the arrival guide lights 1a and 1b of the first vehicle. Between the DC power supply, a standby relay 14 is connected in series with a contact 11 that closes when the car is stopped, a contact 12 that closes when the door is closed, and a contact 13 that closes when there is no directionality. This standby relay 1
4 has contacts 5 and 8 which are energized when the contacts 11, 12 and 13 are closed, and which are closed at that time. A resistor 15R connected in series to this contact 5 and a normally open contact 6 of the ascending direction relay of the car are connected in parallel,
This connection body, the contact 7, and the rising light 1a of the arrival guide light are connected in series to the DC power supply. The contact 7 is closed only when at least one of the ascending buttons 1c and 2c on the third floor is pressed and the first car is responding to the call, or when the car on the third floor is stopped. A series connection of a contact 8 and a resistor 16R is connected in parallel with the normally open contact 9 of the descending direction relay of the car, and the connection, the contact 10 and the arrival light 1b of the arrival guide light are connected between the power supplies. ing. This contact 10
The circuit is closed only when at least one of the descending buttons 1d and 2d on the third floor is pressed and the first car is responding to the call, or when the car on the third floor is stopped. Resistor 15R,
16R has the same resistance value. The same applies to the electric circuits of the arrival guide lights of Units 2 to 4, and the description thereof will be omitted.

According to this electric circuit diagram, the rising light 1a of the arrival guide light is turned on in two cases. One of them is when the car is moving in the ascending direction and the ascending button 1c or 2c is pressed, and when the waiting relay 14 and the contact 7 cause the car to be dumped and stopped on the third floor. Is detected. The arrival light 1b of the arrival guide light is lit when the descending button 1d or 2d is pressed and the car is moving in the descending direction, or when the car is abandoned by the standby relay 14 and the contact 10. This is the case when it is detected that the vehicle is in the state and stopped on the third floor. Both lights 1a, 1
In the case of b, the former case lights up brighter than the latter case.

Next, the operation in normal operation will be described.

When the passenger presses the ascending button 1c or 2c on the 3rd floor, the contact points 6, 7 are contacted by the function of the ascending direction relay (not shown).
Is closed, the circuit of contact 6 ... Contact 7 ... rising light 1a is connected to the power source, and the rising light 1a of the first unit is turned on. When the door of Unit 1 is opened and the door is closed after the standard setting time and the vehicle departs, the contact 7 is opened and the rising lamp 1a is turned off. The same operation is performed when the down button 1d or 2d is pressed.

Next, the operation during a quiet period will be described.

It is assumed that Unit 1 arrived on the 3rd floor and passengers got off the car and the door was closed, but there was no call on the other floor and there was no direction to go up or down, and the passenger was left on the 3rd floor. Then, contact 11 ... Contact 12 ... Contact 13 ... Standby relay 14 in FIG.
Circuit is formed between the power supplies, the standby relay 14 is energized and the contacts 5 and 8 thereof are closed. Also, since the car is stopped on the 3rd floor, the contacts 7 and 10 are closed,
Contact 5 ... Resistance 15R ... Contact 7 ... Rising lamp 1a circuit and contact 8 ... Resistance 16R ... Contact 10 ... Exit lamp 1b
Both circuits are formed between the power supplies. Therefore, the rising light 1a and the descending light 1b of Unit 1 both light up, but the resistance 15
Due to the voltage drop due to R and 16R, the ascending light 1a and the descending light 1b light up darker than in the case of the normal state.

In this way, the passenger can confirm the state of the passenger leaving the car according to the lighting state of the arrival guide light, so that the passenger can board without delay even if the door is opened immediately.

According to this embodiment, the standby relay 14 and the contacts 7 and 10 constitute the relay device for detecting the state of the car leaving the car and detecting the state where the car is stopped on the floor. A relay device having the same purpose may be configured by the elements.

〔The invention's effect〕

INDUSTRIAL APPLICABILITY As described above, according to the present invention, the state in which the car is left in the car and the state in which the car is stopped are detected by the relay device, and when this relay device detects this, the rising light of the arrival guide light is transmitted through the resistor. Since the descending lights and the descending lights are connected to the power source, the ascending and descending lights of the arrival guide lights can be lit up darker than in normal times to notify passengers, and passengers on the drop-off floor can immediately board.
