Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an arrival guide light for an elevator that performs group control.

[Conventional technology]

#Managed elevators generally use arrival guide lights instead of position indicator lights in order to operate cars efficiently, as shown in, for example, Japanese Patent Publication No. 53-22333. I don't know which floor the car is traveling on or which floor it has stopped at.

Currently, when a passenger presses the landing button on a certain floor, the arrival guide light of the elevator that responds to the call lights up, and the elevator car usually arrives after about 20 seconds.

[Problem that the invention seeks to solve]

Conventional group control elevators configured as 5 above stop at the 41st floor because cars are abandoned during off-peak hours, and when a passenger presses the hall button at this abandoned floor, the car is Since the door opens immediately, there is a problem in that the door closes before passengers who are far away can get on board.

SUMMARY OF THE INVENTION An object of the present invention is to provide a guide light for a group control elevator that allows even passengers on the same floor to board the elevator without fail.

[Means for solving problems]

In the present invention, a relay device, a resistor, and a guide light are connected in series between a DC power source, and the relay device has contacts that close the series circuit when the car is in an abandoned state and stopped at the floor. It is characterized by

[For production]

Since the present invention has the above-mentioned configuration, when the car is in an abandoned state and is stopped at that floor, the interior light is connected between the power sources via the resistor, so the interior light is connected to the power source through the resistor. In case of inspection, it will be dimmed and passengers can be notified.

〔Example〕

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

FIG. 2 shows the entire hall on the 41st floor, for example the 3rd floor, in a group-controlled elevator having four group-controlled elevators.

The landing doors A to D of the elevators No. 1 to No. 4 are arranged side by side as shown in the figure. A rising light 1a and a descending light 1b, which are interior arrival lights, are installed above the landing door A of Unit 1, and similarly, rising lights 2a and 1b are provided above the landing doors B, C, and D of each aircraft.
3a, 4a, and downlights 2b, 3b, 4b are provided. On the wall between the elevators of Units 1 to 4, there are hall buttons for calls common to each unit, that is, ascending button IC, 2.
c and exit buttons Id and 2d.

FIG. 1 shows the electrical circuit diagram of the arrival interior lights 1a, 11) of the first car. Between the direct current sources, a standby relay 4 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 that closes when there is no directionality. The standby relay 4 is energized when the contacts 11, 12 and 13 are both closed, and has contacts 5 and 8 that close at that time. A resistor 15R is connected in series to this contact 5, and the normally open contact 6 of the ascending direction relay of the next car is connected in parallel, and this successor, contact 7, and the ascending light 1a of the arriving interior light are connected in series to the DC path source. It is connected. Contact point 7 is the third floor climbing button lc,
The circuit is closed only when at least one of 2c is pressed and car No. 1 is responding to a call, or when a car is stopped on the third floor.

Contact 8 is connected in parallel to normally open contact 9 of the car exit direction relay.
and a resistor 16R are connected in series, and these connections, the contact 10, and the downlight 1b of the arrival interior light are connected between the power sources. This contact point 1o is the button ld for getting off on the third floor.
, 2d is pressed and the circuit is closed only when car No. 1 is responding to a call or when a car is stopped on the third floor. Resistors 15R and 16R have the same resistance value.

Furthermore, the electric circuits for the arrival interior lights of Units 2 to 4 are also the same.
The explanation will be omitted.

According to this electric circuit diagram, there are two cases in which the rising light 1a of the arrival room light is lit. One is when the car is moving in the upward direction and the upward button 1c or 2c is pressed, and the other is when the car is in an abandoned state due to v-14 and contact 7 and has stopped on the third floor. This is the case when it is detected. ! The exit light 1b of the arrival interior light turns on when the exit button 1d or 2d is pressed and the car is moving in the direction of exit, and when the waiting relay 14 and contact 10 turn on the car when it is in an abandoned state. This is a case where it is detected that the vehicle is located on the third floor and is stopped on the third floor.

Both lights 1a and 1b are both lit brighter than the latter in both cases.

Next, the operation during normal operation will be explained.

When a passenger presses the ascending button 1c or 2c on the third floor, contacts 6 and 7 are activated by the action of an ascending direction relay (not shown).
is closed, the circuit of contacts 6, 7, and rising light 1a is connected to the m source, and the rising light 1a of No. 1 is turned on. When the door of No. 1 car opens and a predetermined time elapses, the door closes and the train departs, the contact point 7 opens and the ascending light 1a goes out.

The same operation occurs when the exit button 1d or 2d is pressed.

Next, I will explain rkh production during off-peak hours.

Suppose that the first plane arrives on the third floor, passengers get off the car and the door is closed, but there is no call for other floors, and the plane is abandoned on the third floor, where the direction of going up and down is clear. Then, the contacts 11, 12, 13 in Fig. 1
Since the standby relay 140 circuit is formed between the power supplies, the standby relay 14 is energized and its contacts 5.8 are closed. Also, since the car is stopped on the third floor,
Contacts 7 and 10 are closed, contact 5...resistance 15R...contact 7...the rising light 1a circuit, and contact 8...resistance. 16R...Contact 10...A circuit for the downlight 1b is formed between the power supplies. Therefore, both the ascending light 1a and the descending light 1b of the first car are lit, but due to the voltage drop caused by the resistors 15R and 16R, the ascending light 1a and the descending light 1b are lit darker than in the previous normal state.

In this way, passengers can check whether the passenger has dropped off or not, depending on the lighting state of the arrival guide light, so that even if the door is opened immediately, the passenger can board the vehicle without delay.

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

〔Effect of the invention〕

As explained above, the present invention detects the abandoned state of the car and the stopped state on the floor by the relay device fVC, and when this relay device detects this, the arrival guide light is powered on via the resistor. Because of this connection, the arrival guide light can be lit darker than usual to notify passengers, and passengers on the drop-off floor can board immediately.
