Abstract

PURPOSE:To reduce the opening width of an elevator door to its required minimum when an elevator with a wide entrance is utilized only by persons by providing a half-opening detecting switch and a stopping means for stopping opening operation of the door when the half opening detecting switch is operated as the door is opened after a man-carriage selecting switch is operated. CONSTITUTION:Normal opening/closing operation of a door 2 is carried out by operation of a complete opening detecting switch 31 for detecting the completely-opened state of the door 2 and a complete-closing detecting switch 32 for detecting the completely-closed state of the door 2, and the door is completely opened or closed. In the case of opening the door just enough for some persons to pass through it, a man-carriage selecting switch 33 is turned on. A door opening operation relay 12 for the opening operation of the door 2, a door-closing operation relay 11 for the closing operation of the door 2, and a half-opening operation relay 13 for stopping the door 2 approximately at the center of the entrance space, are connected in parallel between power sources P and N. A series circuit consisting of constantly opened contacts 11a1 and 12a2 and a series circuit consisting of constantly-opened contacts 12a1 and 11a2 are provided between the power sources P and N.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a door opening/closing control device for an elevator, and more particularly to a door opening/closing control device for an elevator suitable for an incoming elevator with a wide frontage.

[Conventional technology]

In general, inbound elevators that mainly transport people and cargo have wide door openings, so for example,
As described in Publication No. 9, a door is constructed from a plurality of panels, and these panels are linked to perform a full opening operation.

[Problem to be solved by the invention]

The door opening/closing control device for conventional elevators was configured as described above, so if only one person was getting on and off the elevator, a small opening would be sufficient for getting on and off, but it would be difficult to fully open and close the wide opening. This means that it takes a long time to open and close the door, and the elevator stops at each floor and you have to get on and off the same way over and over again.
Even though it only needs to be open for a short period of time, it ends up costing a lot of time.

An object of the present invention is to provide a door opening/closing control device for an elevator that can open and close doors efficiently.

[Means to solve the problem]

The features of the present invention include a half-open detection switch that detects when the door is opened to a predetermined position in the middle of the frontage, a switch that selects whether the user is a person or cargo, and a switch that selects whether the user is a person or cargo. A stopping means is provided for stopping the opening operation of the door when the half-open detection switch is operated as the door is opened after the switch is operated.

[Effect]

With the above configuration, when only one person gets on and off,
Set the arrival selection switch to the ``1 person'' side. Then, when the door reaches the position of the half-open detection switch while the door is open, the half-open detection switch is activated, the stop means stops the door drive motor, and the door is opened to a predetermined position in the middle of the frontage. Stop. In this way, the arrival selection switch opens the door to the minimum width necessary for a person to get on and off, allowing the door to depart as soon as the person has finished getting on and off, allowing efficient door opening/closing control. can be done.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. FIG. 1 is a plan view of the car 1 seen from above, and the door 2, which is made up of three panels 21 to 23, is
(See Figure 3), the normally performed opening/closing operation of the door 2 is performed by the operation of the full open detection switch 31 that detects that the door 2 is fully opened, and the full open detection switch 32 that detects that the door 2 is fully closed. fully opened and fully closed. When it is only necessary to open the door a little to allow people to get on and off, the arrival selection switch 33 is turned on. Then, when the door 2 reaches approximately the middle position of the frontage (this position is arbitrarily predetermined), the half-open detection switch 34 detects this, and the stop circuit shown in FIG. 3 maintains the door 2 in the half-open state.

Between the power supplies P and N, a door opening operation relay 12 for opening the door 2, a door closing operation relay 11 for opening the door 2, and a door closing operation relay 11 for opening the door 2 are arranged so that the door 2 stops at a position approximately in the middle of the frontage. A half-open operation relay 13 is connected in parallel.

Each operating relay is configured with contacts connected in series, which are the conditions for energizing the operating relay.
The door opening operation relay 12 has a normally open contact 42a of a door opening command relay (not shown), parallel contacts of normally closed contacts 34b and 13b, and a normally closed contact 31b connected in series. The door closing operation relay 11 includes a normally open contact 4 of a door closing command relay (not shown).
1a and a normally closed contact 32b are connected in series and are configured to be energized from when a command to close one door is issued until the door is fully closed. The half-open operation relay 13 is directly connected to an arrival selection switch 33 installed inside the car, and an arrival selection switch 331...33n installed at the landing of each floor. Arrival selection switch 33□ at each platform...
- Normally open contacts 15□a...15na of each floor relay 151, 15n are connected in series to 33n. A floor position detector 16 is connected in series to each floor relay 15□...15n.

This floor position detector 16 energizes the floor relays 15□...15n of the floor on which the car 1 is stopped.

Further, a series circuit consisting of normally open contacts 11a1 and 12a and a series circuit consisting of normally open contacts 12a1 and 11a2 are provided between power supplies P and N.

Between the contacts of these series circuits, the drive motor 5 for the door 2 (
armature) is connected to the field coil 6, which is electrically connected in parallel, control resistors 7 and 8, and a normally closed contact 11b,
12b, the door 2 is opened and closed.

The door 2 of the receiving elevator having a wide frontage configured as described above performs the following opening/closing operation depending on the situation.

Normally, the door 2 is fully open and fully closed, and at this time, the arrival selection switches 33, 33□...33n are not turned on, and the door 2 of the car that has reached the destination floor is fully closed. At this time, a door open command relay (not shown) is energized and the normally open contact 42a is closed. Since the normally closed contacts 13b and 31b are both closed, the door opening operation relay 12 is energized, and as a result, the power supply P - the normally open contact 12a, - the drive motor 5 (armature) - the control resistor 7 - the normally open contact 12a2ff
A circuit called i source N is formed, and the power source P-field coil 6-
The drive motor 5 (i11i machine) is driven in the door opening direction by the action of the field coil 6 excited by a circuit called power supply N. When the door 2 approaches fully open and the fully open detection switch 31 detects this, the normally closed contact 31b opens and the single door open operation relay 12 is deenergized, and the normally open contacts 12a and 12a
, opens and the normally closed contact 12b closes, thereby stopping the drive motor 5 (armature) and stopping in the fully open state. When a predetermined period of time has elapsed, a door closing command relay (not shown) is energized, the normally open contact 41a is closed, and the door closing operation relay 11 is energized. As a result, the power supply P-normally open contact 11a
1 - control resistor 7 - drive motor 5 (armature) - normally open contact 11a2 - power supply N circuit and the excited field coil 6 reverse the drive motor 5 (armature) and close the door. drive in the direction. When the fully closed state is reached, the fully closed detection switch 32 detects this, the normally closed contact 32b opens, the door closing operation relay 11 is deenergized, and the drive motor 5 (armature)
stops. By such opening/closing operations, that is, by fully opening and closing the door 2, luggage can be smoothly carried in and out.

When only people get on and off, the arrival selection switches 331...33n, 33 on the floor or in the car are turned on.

This energizes the half-open operation relay 13 and opens the normally closed contact 13b. In this condition.

When the car arrives at the destination floor, the normally open contact 42a is closed, the door opening relay 12 is energized, and the fully closed door 2 begins to open, as in normal times. Then, when the door 2 reaches approximately the middle position of the frontage.

The half-open detection switch 34 operates and the normally closed contact 34b opens. At this time, the normally closed contact 13b is also open, so the door opening operation relay 12 is deenergized, and the contact points around the drive motor 5 (armature), etc. Due to this stop circuit, the door 2 is stopped in a half-open state. Then, after a predetermined period of time has elapsed, the normally closed contact 41
a is turned on, the drive motor 5 (armature) is driven in reverse, becomes fully open, and ends its operation. As a result, the time required for opening and closing the door 2 is minimized, and the door 2 can be opened and closed efficiently for people getting on and off the vehicle. In addition, even if you suddenly have to bring in luggage, you can use the arrival selection switch 33□...3 on the landing floor.
3n and the in-cart arrival selection switch 33 are released.
Since the fully open operation can be returned immediately, appropriate opening and closing operations can be performed depending on the situation.

〔Effect of the invention〕

Arrival selection switches are installed in the landing and in the car, and half-open detectors are installed at arbitrary positions along the doorway to issue a signal to stop door opening. Minimize the width.
