Abstract

PURPOSE:To improve facility, and to conserve energy by adjusting a door driving gear by detecting the place, width and speed of a passing body by a body detector while arithmetically operating the position of opening and closing, opening and speed of opening and closing of a door by an arithmetic unit. CONSTITUTION:The place of passage, speed and width of a man, a body, etc., approaching to the inlet side and the outlet side of a door are detected by detectors 1, 7 respectively. The opening and speed of opening and closing of one-side doors 3, 2 are fed back to a driving controller 15 by detectors 12, 13 respectively. The opening and speed of opening and closing of the doors corresponding to the passing body are arithmetically operated by the detecting signals of the detectors 1, 7 by an arithmetic unit 14, and transmitted over the driving controller 15. Driving sources 10, 11 are moved in accordance with the operation command of the driving controller 15, door transmission gears 8, 9 are moved, and the doors 3, 2 are opened and closed. Accordingly, the man, the body, etc., can pass without stoppage at the time of passage while the replacement of the indoor air and the outside air is inhibited, energy loss can be reduced, and a cold countermeasure, in which a doorway is doubled, can be omitted.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic door, and more particularly to an automatic door that can be opened and closed.

[0002]

2. Description of the Related Art In the operation of a conventional automatic door, as shown in FIG. 3, the object detectors 16 and 17 detect whether or not there are objects in their respective operating ranges 18 and 19 to open and close the door. Is going. The door opens and closes at a preset speed, opens to the open end, and is in the fully open state. After the object passes through the door, the operating ranges 18, 19 of the object detectors 16, 17
The doors 2 and 3 are closed after a certain period of time after the disappearance.

That is, the object is simply detected, and the opening and closing of the entire door is repeated depending on whether the object is present or not.

[0004]

When an object passing through the door of this system is detected, the door is fully opened up to the open end regardless of its width.

Even if the two-door door moves to the left, the two left-right doors are fully opened. For a vehicle approaching at a low speed, the door can be opened and passed easily at a timely timing, but for a vehicle approaching at a high speed, the door is slow to open so that it is forced to stop in front of the door. Therefore, at the entrance and exit of a building, when the interior of the building is being air-conditioned, such as cooling and heating, the energy lost due to the fully open state of the door is large, and an object with a narrow width can be used for a wide door. When passing, it is not suitable for energy saving that the door is fully opened. Also, if the speed of opening and closing the passing object does not match the passing speed of the object,
It causes some discomfort due to waiting and rushing.

From the above point of view, in the conventional system,
There are many problems in terms of safety and energy saving. Furthermore, if the moving object is a person, even if the moving object is compromised, the moving object is not limited to a person and there is a limit in terms of usability when considering unmanned and automation.

The object of the present invention is to solve the above-mentioned drawbacks of the prior art, and to detect the passing position, speed, and width of a passing object or a person in advance, and open or close the door correspondingly to detect the passing position. An object of the present invention is to provide an automatic door device that allows an object to pass through naturally without stopping and also to prevent energy loss such as air conditioning.

[0008]

SUMMARY OF THE INVENTION The above object of the present invention is to provide an automatic door including a detector for an object passing through, a drive control device for instructing opening and closing of the door by the detection signal, and an automatic door including a door drive device. The object detector detects the passing position of the object, the width of the object, and the passing speed, and the arithmetic unit belonging to the drive control device calculates the opening / closing position, the opening degree, and the opening / closing speed of the door to determine the door driving device. An automatic door characterized by adjusting.

Is achieved by

An optical sensor can be generally used as the object detector of the present invention.

The arithmetic unit belonging to the drive control apparatus of the present invention allows a slight margin to the left and right for the passage position of an object passing therethrough, and indicates the opening / closing width of each door when it touches both doors. The door drive device includes a door drive source and a transmission device. It is desirable to set a certain range for the passage speed and adjust the opening / closing speed within this range.
This device eliminates unnecessary and unnecessary door opening,
Energy loss such as air conditioning can be minimized.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an embodiment of the device construction of an automatic door according to the present invention, and its operation will be described. Detector 1 is the door A
On the side, the detector 7 is a detector on the B side of the door for the passing position, speed and width of a person or object approaching the door. Reference numerals 8 and 9 denote transmission devices for transmitting opening / closing forces from the drive sources 10 and 11 of the one-side doors 2 and 3 to the one-side doors 2 and 3, respectively. Reference numerals 12 and 13 denote detectors that feed back the opening degrees and opening / closing speeds of the one-side doors 2 and 3 to the drive control device. Reference numeral 14 is an arithmetic unit belonging to the drive control unit, which calculates a door opening and an opening / closing speed suitable for a passing object according to the detection signals of the detectors 1 and 7, and transmits the calculated door opening and opening / closing speed to the drive control unit 15.
The drive source 1 according to the operation command from the drive control device 15.
0 and 11 move and move the transmission devices 8 and 9 of the door to open and close the door. The operation of the automatic door of the present invention will be described with reference to FIG. For example, when the passing object B approaches at the width, position, and speed shown in FIG. 2, the door also opens the one-side doors 2 and 3 to the widths of 2a and 3a, with the allowance of the passing object width. At this time, the door opening / closing speed is calculated and set so that the approaching object does not stop in front of the one-side doors 2, 3. The object B that has passed through the door closes the one-side door 2a according to the speed at the time of passage.

Further, as another example, when the passing object A approaches, the one-side door opens according to the width thereof as shown by 3b. In that case, the one-sided door 2 of 2 remains closed.

When A approaches the door at a high speed, the door must be set to open faster than the opening / closing speed of the passing object B.

Further, by utilizing this control device,
It goes without saying that the functions can be expanded such as use for crime prevention and remote control.

[0016]

The following effects can be obtained by changing the door opening degree and the opening / closing speed according to the passing object by the automatic door of the present invention.

(1) It does not stop when passing through an automatic door.

(2) In a place where air conditioning is performed in a room, it is possible to reduce the exchange of air between the room and the outside air and reduce energy loss.

3 In cold regions, the indoor and outdoor entrances are doubled to prevent cold air, but this can be omitted.

4 When passing objects, they can pass without waiting for each other.

As described above, the effect of the present invention is tremendous, and it can be said that it has many applicability in terms of energy saving and safety.
