Description

[Detailed Description of the Invention] This invention relates to a parallel elevator signaling device,
The object is to provide a device of this kind that can reduce the cost by reducing the number of installed acoustic indicators when an acoustic display is used in conjunction with a visual display.

In a signaling system where multiple elevators are installed side by side, when a hall call occurs or when an elevator arrives, an acoustic display (gong, chime, etc.) is used as a hall lantern (guide light) to display and guide the service elevator. This is used in conjunction with other visual displays to draw the attention of customers waiting in the hall.

Conventionally, this acoustic indicator is provided for each elevator.

However, although this acoustic display has the effect of alerting customers waiting in the hall by its sound, it has been found that this sound alone does not have the function of providing guidance or reliably indicating the arrival elevator.

In other words, a hall passenger who notices that an elevator has been guided or whose arrival has been predicted by the sound then looks at the guide light or arrival forecast light and goes to the entrance/exit of the elevator that has been guided or whose arrival has been predicted.

The present invention has been made in view of one or more points, and includes visual display of arrival or service elevators by means of arrival forecast lights or guide lights, and an acoustic display shared by a group of two or more elevators.

The present invention will be explained below using an illustrative embodiment.

FIG. 1 shows an embodiment of the present invention with respect to the elevator arrangement, and FIG. One acoustic indicator A will be provided for each floor for ascending and descending directions.

Figures B and C show the case where the elevator groups B1 to B6 are arranged facing each other, and in this case, as shown in B, two sets of acoustic indicators A1 of the same operation are installed in parallel in the elevators B1 to B6. , B out of elevator groups B1 to B6 as shown in C.
1-B3. Consider B4 to B6 as a small group, and use the acoustic display A2 in elevators B1 to B3, and
6 may operate the acoustic display A3.

Figures 2 and 3 show the operating electrical circuits in Figure 1A, and only the circuit on floor F is shown, but similar circuits connected from US and DS are also shown on other floors. is necessary.

In Fig. 2, e is the power supply, SFU is the acoustic indicator for ascending floor F, SFD is the acoustic indicator for descending floor F, and FA-FD is the deceleration of elevators B1 to B4 to floor F. Relay contact that turns on when stopping, UPA-
UPD is a relay contact that is turned on when the elevators B1 to B4 are in upward operation, and DNA to DND are relay contacts that are turned on when elevators B1 to B4 are in downward operation, respectively.5
DA-5DD is a relay contact that turns on when elevators B1 to B4 decelerate, and US and UD are for ascending to other floors.

This is the terminal connected to the descending acoustic indicator.

Now, when the elevator B1 reaches the floor F and is ready to decelerate and stop, the circuit e-8FU-FA UPA-8DAe
The acoustic indicator SFU in the ascending direction of the floor F is operated.

(At this time, the hall lantern also operates using a similar circuit, but it is omitted here.

Further, since the elevator control circuit is also a known circuit, the description thereof will be omitted.

) When the elevator B1 decelerates and stops, the relay SDA turns off, so the acoustic indicator SFU stops operating.

Further, when the elevator B2 reaches the floor F and comes to a deceleration stop state, the circuit e-8FU-F B-UPB-8, DB-e causes the acoustic indicator SFU to operate in the same manner.

In the descending direction of the floor F, the acoustic display SFD is operated in the same manner.

FIG. 3 shows another embodiment, and in FIG.
-UFD is a relay contact that operates when elevators B1 to B4 respond to an ascending hall call on floor F, and DFA-
DFDs are relay contacts that operate when each of the elevators B1-B4 responds to a down hall call for floor F.

In addition to the operation shown in FIG. 2, the one shown in FIG. 3 performs the following operations.

Relay contacts UFA-UFD and UFA-DFD are circuits for displaying and guiding a service elevator when a hall call occurs.

That is, for example, when the elevator B1 takes over as a service elevator due to the generation of an up hall call, the acoustic indicator SFU is driven and operated by the circuit e-8FU-UFA-e.

Thereafter, as explained in FIG. 2, when the elevator B1 becomes decelerated and stopped, the acoustic indicator SFU is operated again.

At this time, the sound indicator SFU is driven by the relay contact aUFA, turns off the sound indicator SFU for a sufficient time (generally about 1 second) to make the next sound display, and the relay contact SDA is driven by the start of elevator deceleration. What is necessary is to provide an interlock in sequence.

Further, even if the relay contact UFA is turned off or bUFB is turned on during a service elevator, the acoustic indicator can be operated even if the service elevator is changed by using the same timing.

The implementation circuit diagrams shown in FIGS. 1B and 1C can also be easily inferred from FIGS. 2 and 3, so their explanation will be omitted.

As described above, this invention does not provide an acoustic indicator for each elevator, but instead shares the acoustic indicator with a group of two or more elevators. Therefore, the cost can be reduced by reducing the number of installed acoustic indicators and the number of wires in the elevator hoistway. It has the great effect of being able to reduce the amount of heat used and still being functionally equivalent to the conventional one.
