Abstract

PROBLEM TO BE SOLVED: To enhance the operation efficiency of an elevator by making its door into a state of being half-opened in the case where a passenger gets on the car. SOLUTION: A cargo carrying landing call device 2 and a passenger carrying landing call device 3 both are installed in an elevator hall 4, and also a half- open detecting switch MLS detecting a fact that a door 4 is almost reached to an intermediate position is installed in addition, and in this constitution, when the passenger carrying landing call device 3 is operated, the half-open detecting switch MLS is made into effect, and thereby the door 4 is so constituted to be stopped at the intermediate position.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door control device for a passenger elevator, and more particularly to a door control device for a passenger elevator suitable for a passenger elevator having a wide frontage.

[0002]

2. Description of the Related Art Generally, since an elevator for a person-carrying person carries a luggage in addition to a person, the frontage of a door must be wide. Therefore, for example, as described in Japanese Utility Model Application Laid-Open No. 52-119259, a door is composed of a plurality of panels, and the door is configured to open and close by interlocking with one of these panels.

[0003]

Since the conventional control device for the door of the elevator for the passenger load is constructed as described above,
When passengers get on and off with this passenger-carrying elevator, it is enough to get on and off with a small frontage, but since the wide frontage is fully opened and fully closed, extra time is required and the operating efficiency of the elevator is increased. There was a problem that it decreased.

The present invention has been made in view of the above-mentioned drawbacks, and an object thereof is to provide a control device for an elevator door for a cargo that can efficiently open and close a door for an elevator for a cargo. .

[0005]

[Means for Solving the Problems] This purpose is
And a door control device for a passenger elevator for controlling opening and closing of a door in response to a call from the first calling device, wherein a second calling device and the above-mentioned second calling device are provided in the vicinity of the first calling device. A half-open detection switch is provided for detecting that the door has reached an almost intermediate position, and when the second calling device is operated,
This is achieved by providing means for attracting the car of the elevator and enabling the half-open detection switch to stop the door at the intermediate position.

[0006]

Since the present invention is constructed as described above, if the first calling device is operated when carrying a load, the half-open detection switch is disabled and the door is fully opened and fully closed. Can be transported to.

On the other hand, when only the person uses the second calling device, the half-open detection switch becomes effective,
The door starts to open, and when the door reaches the intermediate position, the half-open detection switch is activated and the door stops in the half-open state. Therefore, the opening and closing time of the door is about half that in full opening and closing, unnecessary door opening and closing operations are eliminated, and the operating efficiency of the elevator can be significantly improved.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

FIG. 2 is an overall explanatory view of a control device for a door of an elevator for a manpower according to the present invention. In the figure, 1 is a hall, 2 and 3 are hall call devices for carrying luggage and hall call devices provided for the hall 1, and 4 is a door of the hall 1 composed of two panels. Switches OLS and MLS that detect that the door 4 is fully open and half open, and a switch CL that detects that the door 4 is fully closed.
S is provided. When the hall call device 2 for carrying luggage is operated, the door 4 is fully opened via a control device (not shown), and when the hall call device 3 for carrying people is operated, the door 4 is half opened.

FIG. 1 is an electric circuit diagram showing an embodiment of a control device for an elevator door for a passenger cargo according to the present invention. The electric circuit diagram is shown only for the first floor, for example, for the second floor.
In the figure, P and N are DC power supply terminals, 2UNB and 2DN.
B is a landing button for ascending and descending luggage on the second floor, 2U
N and 2DN are relays that are activated when these landing buttons 2UNB and 2DNB are operated.
Similarly, 2UNB and 2DNB are landing buttons for ascending and descending people on the second floor, and 2UM and 2DM are these landing buttons.

Relays that are activated when you land on the floor, AXUa, AX
Da is its a contact, AXUb, AXDb is its b contact,
DZ ₁ , DZ ₂ and DZ ₃ are zone detection contacts for detecting that the car is within the predetermined range on the second floor, and Ua and Da are relays (not shown) that are energized when the car is moving up or down.
It is a contact point. DO, DC is a relay to provide a door-opening and door closing command of door 4, DOb and DCb ₁ ~DCb ₃ thereof b contacts, DSa, DSb the auxiliary relay (not shown) gives an instruction of the door closing the door 4 a contact And b contact.

Next, the operation of this embodiment will be described.

First, the case of carrying luggage will be described. It is assumed that the luggage carrier operates the ascending landing button 2UNB for luggage transportation on the second floor. P-2UNB-2Pb
Relay 2UN is energized by the circuit of ₃ -2UN-N,
It is self-held via the contact 2UNa. The car travels toward the second floor by a control device (not shown) and lands on the floor.

At this time, since the contact DSb is closed,
_{P-DSb-DZ 3 -AXUb-} AXDb-DCb 3 -O
The relay DO is energized by the circuit of LS-DO-N, the door 4 starts to open, the switch OLS opens at the end of the door opening, and the relay DO deactivates. When the luggage is brought into the car and a predetermined time has passed, the contact DSa is closed and the relay DC is energized,
The door 4 starts to close, the switch CLS is opened at the open end of the door, the relay DC is de-energized, and the car runs toward a predetermined floor.
When the car lands on the second floor, the contact 2Pb ₃ opens, the relay 2UN is deenergized, and the initial state is restored.

Next, a case where only a person is carried will be described.
In this case, the user is, for example, a person on the second floor, an ascending hall button 2U.
Operate M. Is energized relay 2UM is the same operation as described above, closes the contact 2UMa _2, P-2UMa ₂ -DZ
_1- Ua-DCb _1- AXU-N circuit for relay AX
U is energized and self-held by the contact AXUa. When the car runs toward the second floor and gets on the floor, in this case contact point A
Since XUb is open, P-DSb-DZ ₃ -MLS
-DCb ₃ -OLS-DO-N circuit for relay DO
Is pushed and the door 4 starts to open. Then, when the door 4 reaches the intermediate position, the switch MLS is opened, the relay DO is deenergized, the door 4 is in a half-open state, the user gets into the car, and after a lapse of a predetermined time, the contact DSa is closed and the same operation as above. Thereby, the door 4 is closed and the vehicle runs toward a predetermined floor. As described above, in the case of carrying only a person, when the person carrying hall button is operated, the door is opened halfway, so that the opening / closing time of the door is shortened and the driving efficiency is improved.

[0015]

As described above, according to the present invention, the door is fully opened when the luggage carrying landing button is operated, and the door is half opened when the person carrying landing button is operated. The door is fully opened in the same manner as in the conventional case, while the door is half-opened when only a person is transported, so that the opening / closing time of the door is about half that of the fully opened door, and the elevator operating efficiency is improved.
