JPH10114476A - Specific nonstop floor switching device for elevator - Google Patents

Abstract

PROBLEM TO BE SOLVED: To distinguish a nonstop floor from a landing on the specific nonstop floor by lighting and flashing a call button on the specific nonstop floor when the specific floor is decided as a nonstop floor. SOLUTION: When an uppermost floor nonstop command switch SKEY is operated, a closed circuit is formed of a direct current power source terminal P, the uppermost floor nonstop command switch SKEY, an uppermost floor nonstop detection relay SNST, and a direct current power source terminal N, and the uppermost floor nonstop detection relay SNST is energized. In this way, an uppermost floor downward landing call button detection relay SHD is restricted by means of an uppermost floor nonstop detection contact SNSTb and cannot be inputted even when an uppermost floor downward landing call button SD is operated, so that on the uppermost floor, use of an elevator is restricted and the elevator dose not stop. At the same time, a closed circuit is formed of the direct current power source terminal P, a flashing contact FL, the uppermost floor nonstop detection contact SNSTa, the uppermost floor downward landing call button lamp SDL, and the direct current power source terminal N, and the uppermost floor downward landing call button lamp SDL is flashingly indicated.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a specific floor non-stop switching device for an elevator.

[0002]

2. Description of the Related Art A conventional non-stop switching device for a specific floor of an elevator is provided with a non-stop switch for specific floor non-stop in order to make the specific floor non-stop at an operation panel or a reference floor in a car. Control is performed so that the hall call on the floor set as the non-stop floor is invalidated by the switch.

[0003]

A conventional elevator non-stop non-stop switching device has no means for determining whether a specific floor is non-stop from a non-stop specific floor. If the elevator does not respond by operating the call button, it was not possible to determine whether it was a malfunction or the specific floor was not stopped. In addition, the addition of a non-stop dedicated indicator light has been postponed because it would increase the price significantly.

An object of the present invention is to provide an elevator non-stop non-stop switching device for an elevator, which can easily and inexpensively determine whether a specific floor is non-stop from a stop at a specific floor. Is to do.

[0005]

In order to achieve the above object, the present invention relates to a specific floor non-stop switching device for an elevator having a specific floor non-stop changeover switch for preventing a car from stopping at a specific floor. Is set to be non-stop, the call button of the landing on the specific floor where the stop is performed is blinked.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention is shown in FIG.
This will be described with reference to FIG. Here, FIG. 1 is a block diagram showing a configuration of one embodiment of the present invention.

This embodiment is a case where the top floor is not stopped. As shown in FIG. 1, a top floor non-stop command key provided on an operation panel in an elevator car between DC power supply terminals P and N. Switch SKEY and top floor non-stop detection relay SN
STs are connected in series. A top floor lower landing call button SD, a top floor non-stop detection contact point SNSTb, and a top floor lower landing call button detection relay SHD are connected in series.

Further, a series connection circuit of a blinking contact FL and a top floor non-stop detection contact SNSTa is connected in parallel to the DC power supply circuit P, a bottom floor landing call button lamp lighting contact SHDLa, and a top floor non-stop detection contact SNSTa. This is connected in series with the top floor lower landing call button lamp SDL.

In the embodiment having such a configuration, the blinking contact FL and the top floor detecting contact SNSTa constitute a blinking circuit of a hall call button lamp.

Next, the operation of the embodiment having such a configuration will be described.

For example, when the top floor is not stopped, the DC power supply terminal P, the top floor down hall call button SD,
A closed circuit is formed by the top floor non-stop detection contact point SNSTb, the top floor down hall call button detection relay SHD, and the DC power supply terminal N. When the top floor down hall call button SD is operated, the top floor down hall call button detection is performed. Relay SHD is energized. At the same time, a closed circuit is formed by the DC power supply terminal P, the top floor lower hall call button lamp lighting contact SHDLa, the upper floor lower hall call button lamp SDL, and the DC power terminal N, and the top floor lower hall call button lamp SDL is continuously lit. Is done. If the top floor lower hall call button SD is not operated, the upper floor lower hall call button detection relay SHD is not energized. The lamp SKDL is turned off.

When the building manager operates the top floor non-stop command key switch SKEY attached to the in-car operation panel in order to make the top floor non-stop, the DC power supply terminals P and
A closed circuit is formed by the top floor non-stop command key switch SKEY, the top floor non-stop detection relay SNST, and the DC power supply terminal N, and the top floor non-stop detection relay SNST is energized. Since the top floor non-stop detection relay SNST is turned on, the top floor lower landing call button detection relay SHD is limited to the top floor non-stop detection contact point SNSTb and cannot be turned on even if the top floor lower landing call button SD is operated. The floor is non-stop due to limited elevator use. At the same time, a closed circuit is formed by the DC power supply P, the blinking contact FL, the top floor non-stop detection contact SNSTa, the top floor lower landing call button lamp SDL, and the DC power supply terminal N, and the top floor lower landing call button lamp SDL blinks. indicate.

As described above, the top floor lower landing call button lamp SDL is turned on or off when the top floor is not stopped. When the top floor is not stopped, it flashes. Therefore, it can be easily determined whether or not the top floor is not stopped at the landing.

[0014]

As described above, according to the present invention, when the uppermost floor is not stopped, the lowermost floor call button lamp SDL blinks to indicate that the uppermost floor is not stopped. Inexpensive and easy to determine.
