Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a car position display device for a crane elevator.

A collection indicator is provided in an elevator landing or an attendant management room to display the position of each car of a plurality of elevators.

However, since there are two cars in one set of a hanging type elevator, if an indicator for indicating the car position is provided for each car, two indicators will be required for one set of elevators.

Therefore, as the number of sets of elevators increases, the number of indicators corresponding to twice the number of sets becomes necessary.

Figure 1 shows an example of a set indicator when the method of providing an indicator for each car is applied to two sets of hanging type elevators. Indicators 2'A r, 2A! correspond to the cars A1, A2, B1, and B2 of the Nosurube type elevator and display the car positions from the 1st floor to the 5th floor, for example. ,'3'B+,
3B snow is arranged in rows.

Providing an indicator for each car in this manner increases the size of the collective indicator, increases the number of display lamps, complicates the circuitry thereof, and increases costs.

Therefore, the present invention provides a common indicator for indicating the position of two cars of the same set in a hanging type elevator, and enables the two car positions to be identified by color coding or by changing the illuminance of the position indicator lamp. The purpose is to provide a display device.

The present invention will be described below with reference to embodiments shown in FIGS. 2 to 4.

Figure 2 shows a schematic diagram of two sets of hanging type elevators, where 10+ and lOn indicate the cars of the hanging type elevator on the first set side, and both cars are 101°10! is the rope 13 wound around the hoist 11 and the deflection wheel 12
As a result, when the car 101 is on the lowest floor 1'F, the snow car 10 is located on the top floor 5F, and the winding machine 11 allows the car 10 to be connected to both ends of the car 10. When the car lOf goes up, the car lOf goes down, so that a so-called crane-type running operation is performed. Also,
Reference numerals 14+ and 14* are the cars of the hanging type elevator on the second set side, and these two cars 14+ and 14* are respectively connected to both ends of a rope 17 wound around the hoisting machine 15 and the deflection wheel 16. When is on the bottom floor IF, car 14! is located on the top floor 5F, and when car 14+ is in the process of being raised by hoisting machine 15, car 14! The so-called crane-type traveling operation is performed in which the vehicle is lowered.

FIG. 3 shows an example of a car position display device (collection indicator) applied to the above-mentioned hanging type elevator. 18 is a display panel, and on this display panel 18 there are shown the first set and the first set. Corresponding to the two sets of hanging type elevators, two rows of car position display indicators 19 and 20 are arranged for each set of car positions from the 1st floor to the 5th floor. Is it the elevator on the 1st set side? 10. , 10
．． In addition, the indicator 20 can simultaneously display the car positions of the second set side elevator, 14+, and 14B.

Figure 4 shows a specific example of a car position display circuit in a hanging type elevator on the first set side.
Reference numeral 9 includes position indicating elements such as lamps L1 to L5 provided corresponding to the first to fifth floors, and each of these position indicating lamps Ll to L5 corresponds to the first to fifth floors of the car 10, respectively. selector contact 811. Sl*,...S1

Connected to power.

5 Note 1. The indicator 20 for indicating the car position of the second set of hanging type elevators also has a circuit configuration similar to that shown in FIG. 4.

The operation of the inventive device configured as described above will be explained.

In the sliding elevator on the first set side, for example, as shown in FIG. , the selector contact 811 on the first floor of the car 101 is turned on, and the power source - selector contact 81 + - lamp Ll-C
) The power supply circuit closes and lights up the lamp L1. This informs the user that Kato 10s is located on the first floor.

On the other hand, in the car 1Of, the selector contact 82 on the 5th floor
Since m is turned on, the circuit of power supply - selector contact 82g - resistor R5 - lamp L5 - θ power supply is closed and lamp L5 is lit, indicating that car 1 (h is located on the 5th floor and C is on At this time, since the resistor R5 is connected in series to the closing circuit of the lamp L5, the DC power supply voltage applied to the lamp L5 is dropped, and as a result, the lamp L5 displays the position of the car 10□. It will be dimly lit with an illuminance lower than the lamp illuminance.Therefore, by looking at the brightness state of the lit display lamp, it is possible to easily confirm in which direction the snow cages 101 and 10 are located using the same indicator 19. become.

Also, regarding the hanging type elevator on the second set side,
When the car 14+ is located on the fourth floor, the lamp L4 of the indicator 20 lights up brightly, as shown in FIG. 3, to guide and display the position of the car 14.

Also, basket 14. Regarding the door 14z, which has the opposite correspondence, the lamp L2 of the indicator 20 shown in FIG. 3 is dimly lit to indicate that it is located on the second floor.

In addition, in this invention, the position display of two cars of the same set in the same indicator is not limited to the method of changing the illuminance of the display lamp as shown in the embodiment, but can also be performed by using a color identification method in which the lighting color is changed. You may do so. As a means for this case, a method of using lamps with different i1 lighting colors may be considered.

As described above, according to the present invention, in a hanging type elevator, the required position of the two keys can be identified and displayed by color-coding or illuminance changes on the display section, so that one indicator can be used to identify two of the same set of positions. The location of each car can be displayed as a guide.

Furthermore, since only one indicator is required, the size of the indicator can be made smaller than the conventional indicator provided for each car, and costs can be reduced.
