Description

The invention relates to a method for controlling a electromechanical drive of a revolving door or the like and a control device for an electromechanical Drive and an electromechanical drive device for such a door.

Electromechanical drives for doors with an are known flapping wing z. B. from DE-OS 32 02 930 and by corresponding swing door drive "GEZE TSA 150". The opening and Closing is done by an electric motor.

A swing door opener "Besam swing door opener IK" is also known. It opens with the help of motor power depending on the installation position outside or inside and closes by spring force. A panic function is built into this known drive, by the door wing is designed as a swing wing, which in Emergency opened manually against the normal opening direction can be.

The invention has for its object a method, a Control device and / or an electromechanical drive establishment of the type mentioned for use at single or double-leaf doors with and without rebate or over to develop further.

The invention solves this problem with the features of the patent Expectations.  

Here, the invention provides a method for controlling a electromechanical drive, after which a control hardware is used with computers that are used to control a Swing door is designed and the control hardware is programmed is done by using an external input or self-learning via a test program run is entered whether a single-leaf or double-leaf door with or without rebate is used. This means that the control hardware is universal for ver different door types including hinged or swing doors can be used and the adaptation to the specific door type can be made through programming.

Programming can be done before or during commissioning consequences. The external input can e.g. B. via a code switch respectively. In the case of a self-learning adjustment, pre- can be seen that during the test program run the wing from his Zero over a small range of rotation angle first in the one and then driven in the opposite direction and the motor current is measured to determine whether the door has one or two leaves and / or whether a rebate or Rollover is present.

The invention further provides a method for controlling a electromechanical swing door drive before by a control hardware used with computers for control a double-leaf revolving door is designed and in use a double-leaf door the control device of one door gels master function and the control device of the other Wing function as a slave or with a single-leaf door the control device of the single wing master function he holds. This also becomes a universal application of the tax Hardware provided so that applications for one and two leaf doors with opening and closing sequence are possible.  

With the master / slave assignment, a hierarchy of Control devices received, creating a compulsory tax tion of the slave wing by the control device of the master wing is made possible.

It is preferably provided that the current state of the master wing and the actual state of the slave wing are independent depend on each other and that the measurement signals of the Master wing and the slave wing of the control device of the Master wing fed and processed there. The The two wings are then controlled by the control establishment of the master wing.

The master / slave assignment for double-leaf doors can be be set arbitrarily, e.g. B. at the first external control of the door operator.

With double-leaf doors with opening and closing sequence with a main and a secondary wing, the main wing opposite the secondary wing opens first and closes last, the master / slave assignment can be made by using the Control device for the first external control of the main wing forming the wing the master function and the secondary wing forming wing receives the slave function or vice versa returns. The master / slave Maintain assignment during subsequent operation, e.g. B. like this as long as the supply voltage is switched on.

The opening sequence control can be realized in that leading the secondary wing when opening the main wing, e.g. B. by moving to the main wing in front of the secondary wing.  

The closing sequence control can be implemented in that when closing the secondary wing the main wing at least in a small angle of rotation range before reaching zero ahead, e.g. B. by closing the main wing in a predetermined waiting position is determined until the Secondary wing has reached the zero position. This is special at preferred embodiments provided that the main wing or its drive when closing the secondary wing with a separate brake that interacts depending on the position of the secondary wing is controlled. With double-leaf pendulum doors are advantageously both drives of the wing equipped with such brakes.

An automatic zero position setting is preferred Executions achieved in that immediately after the one switch the supply voltage the angular position of the the wing is measured and the wing or wings over the An drifted to zero position and held there or if the zero position is not reached after a predetermined time, the process is terminated and then the wing or wings be put on hold and the procedure repeated.

The following are exemplary embodiments in connection with the figures explained in more detail. It shows

Figure 1 is a schematic representation of a two-leaf door with electromechanically driven pendulum wings in the zero position, in plan view.

Fig. 2 shows a corresponding representation of the door in Fig. 1 when opening inwards;

Fig. 3 is a corresponding view as in Figure 1 when opened to the outside.

Fig. 4 is a section at the top of the left swing door in FIG. 1.

The exemplary embodiment in the figures is a two-leaf door with an electromechanical drive. Both wings 1 , 2 are pendulum wings, which are driven from the zero position shown in FIG. 1 Darge about the door axes 1 a and 1 b clockwise and counterclockwise by +/- 90 degrees. From FIGS. 2 and 3 can be seen to open as the vanes 1 and 2, inward and outward B A.

The drive device is placed under the door leaves 1 , 2 , preferably in or on the underside of the upper horizontal door spar. It consists of two drive units 11 , 12 . The drive unit 11 drives the wing 1 and the drive unit 12 drives the wing 2 . With this drive, the leaves are each motor-driven in the opening and then in the closing direction.

Each drive unit 11 , 12 consists of a DC motor 13 with planetary gear 14 and connected bevel gear 15 with an output shaft 16 and also from a control device 17th The control device 17 is preferably housed in a separate box, which is arranged next to or above the modules 13 to 15 . The construction groups 13 , 14 , 15 , 17 are mounted on a ver screwed to the frame 8 mounting plate 18 and covered with a U-profile cap, separate caps for the individual modules 13 to 17 or for each drive unit 11 , 12 seen before are or a continuous cap for the entire drive 11 , 12 can be provided.

The coupling of the output shafts 16 with the door leaves 1 and 2 takes place via a door rail screwed to the upper edge of the wing. Fig. 4 illustrates this for the driven shaft 16 of the left drive unit 11 of the door leaf 1. This applies accordingly to the coupling of the right drive 12 with the wing 2 .

As can be seen in FIG. 4, the output shaft 16 engages in a door rail 20 fastened to the wing 1 in a form-fitting and rotationally fixed manner. It is inserted into an end recess 21 of the door rail and clamped therein by means of screws 23 via end clamps 22 .

The door leaves 1 , 2 are opened by a motor when the drive is controlled by a control device. The usual external control devices can be used, e.g. B. Radar or infrared motion detectors or contact mats or hand switches.

Fig. 2 shows the case that a person approaches from the outside - side A of the door - a control device, not shown, attached controls the drive so that both wings 1 , 2 open towards the inside.

Fig. 3 shows the reverse case where a person approaches from inside - side B of the door. The drive is then controlled to open to the outside by means of an internal control device.

After opening, the leaves 1 , 2 each remain in the maximum open position for a predetermined hold-open time or until the person has passed the door and then just close if motorized.

In the embodiment shown in the figures depending on the opening direction, the door leaves overlap or underslide gend, so that it is necessary that the wings when opening and closing run in a certain order. The over flapping wing is the so-called main wing or gang wing gel. The defeating wing is the secondary or passive wing.

When opening inwards, as Fig. 2 shows, the right wing 2 is overlapping and is therefore controlled so that it leads the left wing 1 when opening. For this purpose, the wing 1 is only rotated out of the zero position shortly after the wing 2 when it is opened.

When closing, the left undermining wing 1 must first come to zero position and only then the overlapping wing 2 . This is achieved in that the wing 2 via a cooperating with its drive 12 separate brake in a predetermined waiting position, for. B. is stopped at an angular position of 30 degrees until the wing 1 has reached the zero position. Then the brake is released and the wing 2 then runs in zero position.

When opening to the outside, as shown in FIG. 3, the opening and closing sequence of the wings 1 , 2 is just reversed. Here, the left wing 1 forms the overlapping main wing and the right wing 2 forms the overlapping secondary wing. The drive is in a corresponding manner, as previously described, controls ge by now hurrying when opening the wing 1 and when closing the wing 1 in a waiting position via a cooperating with its drive 11 , a separate brake is stopped.

When opening and closing the leaves 1 , 2 , the control system provides an opening or closing damping in an angular range shortly before the open or zero position is reached. For this purpose, two microswitches 16 a, 16 b are arranged on the output shafts 16 , the position of which is adjustable in order to set the point of use of the damping. Another microswitch 16 c on each output shaft 16 is used to detect the direction of whether the wing or wings 1 , 2 open outwards or inwards. To detect the zero position, the wings 1 , 2 each cooperate with a microswitch 24 attached to the frame.

The microswitches 16 a, 16 b, 16 c, 24 are used for the actual status detection of the door leaf. The measurement signals are fed to a control hardware and processed there in a computer to generate control signals. Instead of the microswitch, angle encoders, angular momentum counters or the like can also be used.

The control devices 17 of the drives 11 , 12 , each consisting of a measuring device and control hardware, are hierarchically coupled with a so-called master / slave assignment as follows. The control device of one wing has a master function and the control device of the other wing has a slave function.

The current state of the master wing and that of the slave wing are each independent from each other through the measuring device assigned to the wing. The measuring signals of the master wing and the slave wing are the Control device of the master wing fed and processed there works. This will control the master wing of the slave wing is forcibly controlled.

The assignment of the wings as master or slave wings can be made arbitrarily. It can be done automatically in an initialization phase or by manual setting during commissioning. Here wing 1 is defined as the master wing and wing 2 as the slave wing or vice versa. The assignment is maintained as long as the supply voltage is switched on and is only canceled when the supply voltage is switched off. This means that the assignment once defined remains constant for all operating functions of the pendulum wing when opening and closing inwards and outwards.

The following is the process of an initialization phase automatic zero position setting and master / slave assignment described.

The initialization phase begins immediately when the supply voltage is switched on. First, the instantaneous angular position of the individual vanes 1 , 2 is measured. The measurement signals are the assigned Antriebsein units 11 , 12 and the wings 1 , 2 are then rotated by motor to the zero position in Fig. 1. When the zero position is reached, this is measured via the microswitch 24 and reported to the control devices 17 of the drives 11 , 12 .

If after a predetermined time the zero position has not yet is enough, the wings are turned back by motor and the above process is repeated by the position the wing is measured and then the wing in zero position ge be rotated. This process is repeated until the zero location is reached or finally after a few runs canceled and an error message is given.

If the leaves 1 , 2 are in the zero position, the master / slave assignment can take place. In the exemplary embodiment, this happens automatically when the drive is activated for the first time. The master function receives depending on the circuit of the hardware z. B. the wing that forms the main wing when first activated. This means that if the first activation takes place from the outside, as in FIG. 2, the right wing becomes 2 master wings and the left wing 1 slave wing. If the first activation according to FIG. 3 takes place from the inside, the assignment runs in reverse, so that the left wing 1 becomes master and the right wing 2 becomes slave.

As already mentioned, the master / slave assignment can be older natively take place in another circuit so that when first control of the slave secondary wing and the main wing Becomes a master.

A particular advantage in the embodiment shown game is that the control hardware of the drive universal for different types of doors, i.e. for two winged or single winged with and without rebate or with or can be used without rollover.  

The control device is adapted by programming the control hardware accordingly. For this purpose, code switches as in the control devices 17 of the drive units 11 , 12 can be provided, with which it can be entered whether it is a single or double-leaf door with or without a rollover or rebate and which leaf is in or out in which direction of rotation is overturning. In this way it can also be set whether pendulum or stop wings are used.

The setting or programming of the hardware can also be self-learning for special versions, e.g. B. with the aid of a test program running on the door in the initialization phase, in which the relevant actual parameters which characterize the type of door used are measured, e.g. B. Measurement of the motor current of the drives 11 , 12 . Such a test program is carried out by the wings 1 , 2 via their drives 11 and 12, both of which are briefly driven both outwards and then inwards. By comparing the measured motor current curves, the system can know which type of door is used.
