Description

Automatic door and its control device {AUTOMATIC DOOR AND CONTROL APPARATUS THEREOF}

The present invention relates to a driving device of an automatic door. More specifically, in an automatic door used for an elevator door or a front door of a building entrance, both doors can be opened and closed by using a friction clutch action based on a magnetic force of a roller. It relates to a drive of the automatic door to be performed as.

In general, automatic doors, which are used as elevator doors or front doors of front doors, are mostly tied to a timing belt or V-belt which is designed to reciprocate a certain section by the force of a geared motor, so that one side or It is configured to open and close to both left and right sides.

At this time, the rollers are coupled to the upper sides of the doors so that the doors can be slid more smoothly while the doors are suspended on the guide rails. As the ride moves, the door is configured to reciprocate without swinging.

In other words, as shown in FIG. 1, one embodiment of the door driving device 40 in the conventional automatic door as described above will be described. Drive pulleys 41 are respectively provided on both upper sides of the door frame frame 10. ) And the driven pulley 42, the timing belt or V-belt 43 connecting the driving pulley 41 and the driven pulley 42, and the timing belt or V by transmitting power to the driving pulley 41. A drive motor 44 for imparting a moving force to the belt 43, a guide rail 45 provided to be parallel to the timing belt or the V-belt 43 on the lower side of the door frame frame 10, and timing The left door hanger bra which is fixed to both sides of the lower part of the belt or V-belt 43 and the left door 20 is suspended in the lower part and guided by the guide rail 45 together with the main door 20 to be linearly reciprocated. And kets 46 and 46 '. Here, the right side door 30 is suspended by the right side door hanger bracket (not shown) in the lower both sides of the timing belt or the V-belt 43.

However, the left and right doors 20 and 30 are symmetrically moved in opposite directions at all times according to the forward and backward movement of the timing belt or the V-belt, and are simultaneously opened and closed so that the user or the user who moves forward through the door is carried. After the traveling carrier (including a bag) is positioned at the center of the left and right doors 20 and 30, the vehicle does not pass, and retreats from the front of one of the left and right doors, but the user or the travel carrier does not completely pass through the door. If the door is caught by one door and the one door is paused, the other door tries to continue its closing operation, so that the flexible timing belt or the V-belt 43 is extended due to mutual reaction, The toothed engagement position between the timing belt or the V-belt and the driving or driven pulley 42 is shifted from the initial setting position. As a result, in the subsequent door opening and closing, instead of the correct opening and closing operation, there is a risk that either door may not be fully opened and closed.

In other words, when the toothed engagement position of the timing belt or V-belt 43 and the drive or driven pulley 42 is shifted from the initial setting position, for example, the toothed engagement position with the driven pulley 42 is shifted. In this case, the left door is not completely opened and closed, and an abnormal operation occurs in which only the right door is completely opened and closed.

In addition, when the user or the user's travel carrier is caught in one of the left and right doors, for example, the left door 20, the timing belt or the V-belt 43 is cut, and is symmetrical with the right door 30. By not moving to, there is a problem in that the door can not be fully opened and closed.

Therefore, the present invention has been made to solve the above problems, and an object of the present invention, in the automatic door used for the elevator door or the front door of the building entrance, etc., both door opening and closing has a friction clutch action based on the magnetic force of the roller. In order to be carried out asymmetrically by using, and do not use the belt driving method, to provide a door driving device of the automatic door that improves the reduction of the motor efficiency due to the tension of the belt.

In addition, the pinion gear drive force transmission roller 72 is rotatably supported inside the main body rotatably supporting the gear train, and the pinion gears 71 of each of the transmission rollers 72 rotate with each other. They are arranged in pairs to face each other so as to be movable and arranged in two rows.

In addition, since the magnetic force of each of the driving force transmission rollers 72 is manufactured by a powder compression molding process, the magnetic force is surrounded by a protective cap 76 to prevent the magnetic force from being damaged due to an impact.

On the other hand, the door is mainly used as a door of an elevator or a front door of a building porch, and has a door driving gear train 70 disposed in a generally upper center portion of the door frame frame for slidingly opening and closing a plurality of doors. It is controlled and operated by the control device for automatic doors (refer FIG. 8) for controlling a drive mechanism.

Therefore, the control device, front and rear detection sensors 61 and 62 fixed to the upper part of the door frame frame to detect that the person who wants to pass through the building through the door approaching the front door, and the front and rear detection sensors 61, Drive motor 100 for opening and closing the door by receiving a detection signal from the 62, a motor driver 101 for controlling the operation of the drive motor, a rotation sensor 63 for detecting the amount of rotation of the drive motor And a control unit for operating the drive motor to set the maximum and minimum opening and closing positions of the door by calculating a moving distance of the door based on the rotation amount detection signal of the rotation sensor.

Here, the control unit controls the driving motor 100 to operate the driving force transmission roller 72 of the door driving mechanism of claim 1 until the plurality of doors are positioned at the maximum and minimum opening and closing positions. .

The control unit temporarily stops the drive motor 100 when any one of the plurality of doors reaches a set closed position, and then completely opens the plurality of doors simultaneously, and then again opens the entire door. The driving motor 100 is controlled to close, and when the one side door reaches the set opening position, the driving motor 100 is configured to be controlled in reverse with the closing operation.

In addition, the control unit includes a forward and reverse discriminator 64 for generating a detection signal for forward and forward starting the drive motor.

In addition, the controller determines the open / close position in response to the door open / close position detection sensors 65 and 66.

Hereinafter, with reference to the configuration of the present invention, the operation of the device according to the present invention will be described.

First, in setting the height of the door, the guide rails 95 are crosslinked and installed in the door frame frame 10 in a direction crossing them.

At this time, the lower portion of the bracket 50 of the guide rail fixing mechanism abuts on the lower side of the door frame frame 10, and then the upper portion of the bracket 50 is rearward, the rear of the bracket 50 is the door frame It is installed to abut on the inner wall of the frame (10).

In addition, the guide rail fixing mechanism fastens the screw member 53 having a set diameter to a fastening hole formed at one end of the bent portion of the bracket 50, and a spring member 54 at the other end of the screw member 53. After fastening, the upper and front end inner surfaces of the fixing block 56 abut the upper inner wall surface of the front side of the door frame frame 10, and then a plurality of pins fixed in a row in the rear side of the fixing block By elastically placing the spring member 54 between the rear face of the fixing block and the short side of the bent portion via the member 55, the fixed coupling to the door frame frame 10 is completed.

Here, the guide rail 95 is fixedly coupled by a plurality of screws to the front lower side of the bracket (50).

Next, the fastening piece 91 coupled to the upper end surface side of the door is fastened and fixed to the bolt inserted into the roller slider 92 mounted on the guide rail 95 so as to be slidable (see FIG. 4). ). Thus, the suspension structure of the door with respect to the guide rail via the bolt and the slider is completed by the double lock by the normal nut 51 and the lock nut 52.

Next, to describe the driving force transmission process to the door, when the power is applied to the drive motor 100 under the control of the control unit, consisting of a plurality of gears close to the first driven gear 74 on the rotation axis of the motor, Through the gear train 70 for receiving the rotational force of the motor, the driving force transmission roller is rotated forward and backward to open and close the door.

Meanwhile, as another embodiment, as shown in FIG. 6B, in order to reduce noise generated when the rotational force of the driving motor 100 is directly transmitted to the first driven gear 74 on the rotating shaft, Instead of directly engaging the gear train with the gear train, it is further provided through the pulley 104 by a belt 103 transmission wound by the pulley 104 on the first driven gear 74 of the gear train. It may transmit to one driven gear 74.

In addition, the first row rollers and the second row rollers of the driving force transmission roller 72 are dually arranged so as to rotate in opposite directions, so that the left carrier abuts the side and end surfaces of the first row rollers. The right carrier which contacts the side surfaces and end surfaces of the rollers of the second row is moved in opposite directions when the door is moved for opening and closing the door, so that the left and right doors are opened or closed.

Therefore, by the constitutive driving device and the circuit control device for the door according to the present invention, the control unit in response to the detection signal of the open and close position detection sensor (65, 66) the maximum door opening position and the minimum door closing position The door is opened and closed by judging and driving the drive motor 100 forward and backward by the known forward and reverse determination unit 64.

Here, the control unit determines the opening / closing position in response to the door opening / closing position detecting sensors 65 and 66, and sends the control unit to command the start of any one of forward and reverse driving of the motor.

For reference, when the door of any one of the plurality of doors reaches the set closing position, the drive motor 100 is paused, and then the plurality of doors are completely opened at the same time, and then the entire door is closed again. The drive motor 100 is controlled, and when the one side door reaches the set open position, it is instructed to be controlled inversely with the actuation upon closing.

Therefore, when opening or closing the door according to the present invention, a user or a portable article following it is unilaterally biased on either side of the left and right doors to prevent the progress of the door, the existing timing belt or V-belt driven automatic sliding It solves the problems such as resetting of the existing automatic door due to the door's initial position deviation and renovation work by cutting the timing belt or V-belt. By transmitting the driving force required for the door movement through the magnetically engaged coupling capable of sliding movement, rather than gear coupling, it is possible to solve the above-mentioned problems in the prior art.

In other words, the automatic door which is used as the elevator door or the front door of the building entrance is combined so that the roller rotated by the force of the motor-mounted gear train means of the present invention and the carrier that abuts magnetically, reciprocate a certain section. The door is configured to be opened and closed by moving the slider toward one side or both left and right sides along the guide rail.

As described above, in the present invention, the stroke of the drive motor via the gear train is transmitted to the door, so that the contact force of the roller and the carrier which reacts with the magnetic force is transmitted so that the movable force as much as the set force for the door operation is transmitted to the door. In a state in which the state is kept constant, a constant door opening and closing force is applied, so that even if a user or a foreign object is caught on any one side of the plurality of doors, the moving direction is restricted by the user or a foreign object to further advance the door. By preventing, it has the effect of preventing the user's injury and damage to foreign objects.

Meanwhile, among the main components of the driving means, the carrier is friction-transferred to the pair of feed rollers, respectively, to open and close the doors on both sides, but one carrier and the slider are in friction contact with the feed rollers in a row. It may be configured to be able to drive one door.

In addition, the present invention improves the efficiency of the motor by eliminating the influence of the belt tension by not using the belt driving method. For example, in a conventional belt-driven automatic door, it generally has a weight of 60 to 120 kg. When driving the door, it takes about 60 ~ 120 W motor, but in the present invention has a very excellent effect that the automatic transfer of the door with only a low output drive of 10 ~ 20 W.
