EP3088652B1 - Operating start method for an automatic building closure, building closure drive device for use in this method and automatic building closure - Google Patents

Description

The invention relates to an operation start method for setting up operation of an automatic building lock according to the preamble of claim 1. The invention further relates to a building lock drive device according to the preamble of the independent claim.

From the EP 0 544 135 A2 is a method and a device for teaching end positions for actuators of windows, doors, awnings, roller shutters or the like, in which end positions are detected by counting values of an incremental encoder, whereby a motor shutdown device can be provided for teaching the end positions.

From the EP 0 905 592 A1 a method for setting the end positions of an actuator for garage doors driven by an electric motor is known, in which the motor is moved against an end stop, is switched off via an overload switch-off and the electric motor is then automatically moved a certain distance in the opposite direction, in order to then to save the achieved position value as the end position. This position value learned through automatic reversing can be manually readjusted.

From the DE 20 2010 015 105 U1 a drive for a darkening device with an adjustable closure element is known, wherein a drive motor, a control associated with the drive motor and a position measuring arrangement are provided for determining the position of the closure element, wherein in an operating mode of the control the closure element normally operates between two control-technical end positions "opening end position " and “Closing end position” is motor-adjustable and the control end positions can be taught in automatically in an installation mode of the control.

The state of the art further mentions the rolling garage door "RollMatic", which is known from the company brochure "RollMatic garage door RollMatic" from Hörmann KG sales company, as of 05.2014, with the printing date 05.2014, published, among other things, on the Internet.

The RollMatic garage door drive is a rolling shutter as an example of a building shutter drive. The roller garage door is available in a version as an automatic building closure with a roller door drive, which is an example of a building closure drive. The RollMatic garage roller door also has a roller curtain made up of roller door bars or slats, which is an example of a building end wing made up of segments or slats. The roller blind can be wound onto a winding shaft driven by the roller door drive. When the roller blind is wound up, a closing edge of the roller blind moves in the opening direction, thus allowing passage to the garage to be closed. To close the roller shutter, the winding shaft is driven in opposite directions, so that the roller blind unwinds from the winding shaft and the closing edge moves in the closing direction. The drive takes place via the winding shaft, which exerts a driving force on the already unwound area of the roller blind from top to bottom when closing. If the weight of the already unrolled roller blind is ignored, a compressive force is exerted on the roller blind, the direction of travel "closed" acts in the direction of pushing the slats together or, in other words, in the direction of compressing the roller blind. When opening, turning the winding shaft in the opening direction causes a tensile force on the roller blind, which acts in the direction of pulling the slats apart.

A particular advantage of the RollMatic roller garage door is its particularly simple construction. The roller blind is balanced as much as possible using a weight compensation device. The risk that the roller blind hits objects or people, especially when closing, and damages the objects or injuries to people can be avoided by providing a power cut-off on the rolling closure.

A power cut-off has been well known for decades, especially in other types of gate drives such as tow drives. For this purpose, a parameter on the building closure drive, which is dependent on the driving force of the building closure drive, is monitored with regard to exceeding or falling below predetermined thresholds. Such parameters are, for example, the current consumption, voltage consumption, power consumption and / or the speed of an electric motor of the building closure drive. Using one or more of these parameters, you can determine the amount of force that the building closure drive currently has and, if the force is too high, you can switch off or reverse the force.

The same is also the case with the RollMatic automatic roller shutter. This means there is no need for separate sensors on the closing edge and without a separate closing edge safety device.

The possibility of monitoring the safe running of the building end wing further enables a simple operational start procedure in which end positions of the building end wing are taught in in order to be used to control the roller door drive in subsequent operation.

For this purpose, with the RollMatic garage door drive, the roller blind is moved into its opening end position in a learning run up to an end stop provided there. For example, in the area of the side guide or in the area of an end strip, mutual end stops are provided when moving the closing edge area into the opening end position. During the learning run, a connected control unit detects the movement against the opening end stop due to an increase in the opening driving force. The roller shutter drive is equipped with a position sensor that monitors the angular position of the drive shaft and determines these specific positions Rolling door curtain assigned. By knowing the opening end position, a very good reference value for the position sensor can be obtained.

Furthermore, a closing end position is taught in a learning run in the “gate closed” direction. To do this, the roller blind is unwound until the closing edge moves against a mechanical stop (e.g. the floor) at the closing end position and the roller blind is then compressed. This is also detected by an increase in force and monitoring of the parameter correlated to the force, and the corresponding learned closing end position is then used to operate the roller shutter.

For example, the operation takes place in such a way that the speed is reduced shortly before the corresponding end positions are reached, so that a gentle movement against the respective end stop takes place.

In addition, the power cut-off can be active over most of the door's travel, so that if the force is increased impermissibly, an impediment to an obstacle is assumed and a reversal occurs. On the other hand, a reversing limit can be provided based on the learned closing end position. In an area just before the closing end position, between the reversing limit and the closing end position, the control can then be adjusted in such a way that an increase in force is not recognized as hitting an obstacle, but rather as hitting the mechanical stop in the closing end position.

This technology has proven itself and enables a safe and yet very cost-effective and space-saving automatic building closure drive.

The invention has set itself the task of further improving an operating start method for an automatic building closure drive of the type mentioned in the preamble of claim 1 with regard to comfort and building closure.

This task is solved by an operation start method according to claim 1.

An operating procedure using the operating start procedure and an automatic building closure are the subjects of the secondary claims.

Advantageous refinements are the subject of the subclaims.

According to a first aspect, the invention provides an operation starting method for setting up operation of an automatic building closure, which has a building closure wing constructed from a plurality of segments or slats and a building closure drive which is connected to the building closure wing in such a way that driving in the closing direction causes a compression in the direction of the Segments or slats exerted compressive force and driving in the opening direction exerts a tensile force acting in the direction of pulling the segments or slats apart, with the step:

According to a further aspect, the invention relates to a roller door with a building end drive device, comprising a building end drive unit for pushing a building end wing made up of several segments or slats in a closing direction and for pulling the building end wing into one Opening direction and a control unit for controlling the building closure drive unit, the control unit being designed for automatically teaching in a learned closing end position by means of power shutdown in the course of a learning run in the closing direction, characterized by a closing end position fine adjustment device, by means of which a position that is offset from the automatically learned closing end position in the opening direction, can be set as the closing end position.

The building shutter drive device is designed as a rolling shutter drive device for driving a winding shaft of a rolling shutter, on which, as a building wing, a roller blind can be wound up in the opening direction and unrolled in the closing direction.

According to the invention it is provided that the closing end position device device has a closing end position adjustment element for manually adjusting the extent of the displacement of the closing end position. The closing end position setting element has a plurality of predetermined positions for selecting one of several discretely predetermined degrees of offset by which the closing end position is offset from the taught closing end position in the opening direction.

It is preferred that the closing end position adjustment element comprises a potentiometer.

It is preferred that the control unit is set up to carry out the operating start method according to one of the above embodiments and/or to carry out the operating method according to the previously explained embodiment.

A preferred embodiment of the building end drive device is characterized by a relative travel sensor for detecting an angular position of a wing to be connected to the building end Drive shaft of the building end drive unit in order to record the position of the building end wing.

This further aspect of the invention relates to an automatic building closure in the form of a roller door, which has a building closure wing made up of several segments or slats and a building closure drive device according to one of the previously mentioned configurations.

The building closure according to the invention is designed as an automatic roller door, with the building closure wing being designed as a rolling curtain, which can be wound onto a winding shaft that can be driven by the building closure drive device for opening and can be unwound for closing.

In all aspects of the invention, it is preferred that the extent of an offset of the final closing end position from a closing end position learned by power shutdown can be selected in a limited range between 0 and approximately 1.5 segment lengths or slat lengths, in particular between 0 and 1 segment length or slat length.

One of the ideas underlying the invention is, in particular, a fine adjustment of an automatically taught end position "gate closed" by a limited distance in the direction "gate open". This fine adjustment should preferably be carried out in conjunction with a roller shutter.

During the distance learning runs, the RollMatic drive automatically learns the end positions "gate open" and "gate close" due to the increase in current and the drop in speed in the end positions. When determining the end position "Gate Closed", the problem arises today that the last slats immediately before the end position "Gate Close" and depending on the number of slats/gate height do not unwind evenly and reproducibly, which results in an unwanted reversal or a cracking noise. which can occur due to the "buckling" of the last slat due to the high pressure in the hinge or pivot point of the slat.

So far, attempts have been made to limit the angular position of the slats by the number of slats depending on the door height so that the last free slats (which are not guided in the vertical guide rail) are not too steep in the "door closed" end position, but also don't stand too flat.

However, due to the fixed slat height of e.g. 77 mm, depending on the door height, you can only have a limited influence on the angular position of the slats in the “door closed” end position. Initially, with the "critical" gate heights, attempts were made to compensate for this by half a slat (half the slat height), which, on the one hand, caused higher costs and, on the other hand, caused scratches on the surface of the gate. In addition, this would be difficult to implement economically due to the now high level of automation in production.

As a solution, according to an advantageous embodiment of the invention, a limited fine adjustment of the end position "gate closed" in the direction "gate open" is proposed, for example by means of a potentiometer or another adjustment element. For example, the final closing end position is offset from a taught closing end position by approximately one slat height. Advantageously, there is only a limited setting option. It makes sense to choose a limit so that there are no problems with safety standards that suggest a specific maximum reversing limit. A larger distance within which fine adjustment would be possible could therefore lead to difficulties in maintaining the reversing limit.

This idea can reduce manufacturing costs. This might make it possible to do without a slat for some gate heights. Compared to other concepts, safety monitoring is also possible on simply constructed roller shutters without sensors or closing edge guards, purely by switching off the power on the drive, with better comfort and greater operational reliability than previously possible.

For example, using a potentiometer or other adjustment element provided on the drive or a control unit or an operator interface, you can fine-tune the “Gate Closed” end position, as will be explained below using the potentiometer as an example.

Poti to 100% (right stop): The end position "Gate closed" corresponds to the automatically taught end position via force switch-off.

Poti to 50% (middle position): The end position "Gate Close" is shifted in the direction of "Gate Open" by approx. half a slat (22.5° winding shaft revolution) compared to the automatically taught end position during gate travel (all travel except learn-away travel).

Poti to 0% (left stop): The end position "gate closed" is increased by approx. one entire slat
(approx. 45° winding shaft rotation) shifted in the “gate open” direction.

The rotation range of the potentiometer or other adjustment element can be set, for example, in sectors to enable gradual adjustment. For example, the setting range is divided into 5 to 20, preferably 11 sectors. When driving a winding shaft, for example, an adjustment in steps of approx. 4° would be possible.

A possible exemplary embodiment for teaching is described below.

Initial state: The drive is untrained (delivery state or after a reset). 1. A reference movement takes place in the direction Up.

Termination by power shutdown. 2. A route learning trip takes place in the direction of Zu.

Termination by power shutdown.

Now the maximum goal distance has been determined.

Now the gate distance is shortened and saved based on the potentiometer position.

In this exemplary embodiment, the potentiometer position is no longer evaluated during further operation; The shortened goal route is already stored in the memory. 3. A force learning run takes place in the open direction with the old maximum distance.

All further journeys will now take place with the corrected route. 4. A force learning journey takes place in the direction of Zu.

Termination by power shutdown or end of route. 5. There is a journey in the direction of Up.

The drive is now taught in for normal operation.

During a force learning run, for example, the course of the or each parameter monitored for force shutdown is recorded over the door travel distance and used for distance-dependent threshold value monitoring.

It might also be conceivable that the route could be shortened using a potentiometer in the taught-in state. In one embodiment, a maximum distance or a closing end position learned by exceeding the force is learned. During operation, the final closing end position is determined from the taught-in distance and the amount of offset specified via the setting element and used for the control. The latter embodiment has the advantage that automatic re-teaching of the learned closing end positions is also possible and that the shortened distance can currently be determined and updated from a currently learned value of the closing end position and the predetermined extent of the offset in the opening direction.

One goal is to achieve greater operational reliability when it comes to reversing. Additional advantages are the reliable adherence to the reversing limit and the prevention of cracking noises. End customers who place great value on complete closing (no gaps between the slats) can still fulfill this wish with the potentiometer setting of 100%.

Other conventional automatic roller shutters available on the market usually have a tubular motor without force limitation and therefore a different drive principle. The end position setting usually takes place by approaching the end positions in dead man mode and then manually saving the end position. Obstacle detection in the “gate closed” direction is carried out using optical closing edge safety devices. With these conventional roll-up shutters, operational safety and comfort are achieved through other measures that are, however, much more complex in terms of production and handling.

The Fig. 1 to 6 and 9 and 9 show exemplary embodiments for a building closure 10, which has a building closure wing 12 guided in a guide 14 and a building closure drive device 16 for driving the building closure wing 12.

The building closure 10 is designed as a rolling closure and in particular as a rolling door 18, with the building closure wing 12 being designed as a rolling curtain 20, which is made up of several slats 22.

The building closure drive device 16 is designed as a rolling closure drive device and in particular as a roller shutter drive 24, which is designed to drive a winding shaft 26 of the roller shutter 18. By driving the winding shaft 26 in one direction (clockwise in the Fig. 3 and 6 ), the roller blind 20 is wound onto the winding shaft to open the roller shutter 18. When the winding shaft 26 rotates in reverse, the roller blind 20 is unwound from the winding shaft 26 to close the roller shutter 18. In general, the building end wing 12 is driven to be movable in an opening direction and in a closing direction by the building end drive device 16. The building end drive device 16 engages an area of the building end wing 12, which is arranged opposite to a closing edge 28.

In the case of the building end wing 12, which is composed of slats 22 or other segments, this causes driving in the closing direction (downwards into the Figures 3 and 6 ) a driving force on the building end wing 12 in the direction of compressing the building end wing 12 - Compressive force. When driven in the opening direction, the building end wing 12 is loaded in the pulling direction; the slats 22 or other segments 26 are therefore pulled apart.

Like in the 7 and 8 indicated, the building end drive device 16 has a drive unit 30 for motor driving the building end wing 12 and a control unit 32 as well as a position transmitter 34, for example designed as an incremental encoder 36 in the area of a drive shaft 38 of the drive unit 30.

If at least one position of the building end wing 12 is well known, the respective door path and the current position of the building end wing 12 can be determined by counting up or down the pulses of the incremental encoder 36 from the known position. This is done using appropriate software in the control unit 32.

Furthermore, the control unit 32 is connected to the drive unit 30 in such a way that a parameter of the drive unit 30, which is dependent on the respective driving force - e.g. is proportional to the driving force - is monitored in order to detect an impermissible increase in force and a shutdown or To carry out reversal.

For example, a current consumption and a speed of an electric motor of the drive unit 30 are monitored and an impermissible increase in force is detected when a predetermined current threshold is exceeded or when the speed falls below a predetermined speed.

The control unit 32 is further designed to carry out learning runs to teach in operating parameters for the building closure 10 in an operating start procedure.

An exemplary embodiment of the operating start method is explained in more detail below.

First, after initial assembly or a reset of the building closure 10 or the building closure drive device 16, a learning run in the opening direction takes place. The learning run takes place with little force until the building end wing 12 reaches a mechanical stop in the opening end position. This is recognized in the control unit 32 by means of force monitoring. The learning run is ended and the corresponding position of the position sensor 34 is stored in a memory 40 as an opening setting and as a reference value for the door path detection.

A learning run then takes place in the closing direction until the building end wing 12 reaches a mechanical stop in the final closing position and this is detected via the force monitoring. For more details, the winding shaft 26 is driven in the closing direction until the closing edge 28 reaches the mechanical stop formed by the base. The winding shaft 26 is then continued to be driven until all the slats 22 have moved towards one another and an increase in force on the winding shaft is noticeable. This increase in force is detected via force monitoring. The corresponding position is referred to below as the “provisional closing end position” or as the automatically taught closing end position.

A closing end position setting element 42 is provided on the control unit 32, by means of which an operator can carry out a fine adjustment of the closing end position that is actually to be used for control during operation. In one exemplary embodiment, the closing end position setting element 42 comprises a potentiometer 44 on a control board of the control unit 32. The potentiometer 44 can be adjusted in several steps between a maximum position and a minimum position. By selecting one of the settings, the operator can specify that there should be no offset between the actual closing end position and the initially automatically taught closing end position. However, it is also possible by means of the closing end position setting element 42 to set a final closing end position, which is offset by a limited amount in the opening direction from the automatically taught closing end position.

An operator can therefore specify a measure of an offset of the final closing end position relative to the closing end position in the opening direction, which is automatically taught in by means of a force switch-off.

According to an exemplary embodiment of the operating start method, after carrying out the learning run, the operator determines to what extent an offset of the actual closing end position in the opening direction is advantageous in order to avoid problems with an unwanted power switch-off before reaching the closing end position and noises when moving into the closing end position. The final closing end position, offset by the specified amount, is then taught into the memory 40.

In another embodiment, a measure of an offset is specified once by means of the closing end position setting element 42 and then, in later operation, the desired closing end position to be taken into account for the control - which is offset from the automatically taught one by the predetermined amount - is determined from a stored, automatically previously taught closing end position . The latter version has the advantage that updates can also be made when the closing end position is automatically taught in and the amount of offset only needs to be specified once.

Learning runs are then carried out in the opening and closing directions in order to record and teach in the force curve, i.e. the curve of the monitored parameter depending on the route. This force curve is used - taking a tolerance distance into account - as a path-dependent force threshold for later operation.

The final closing end position, which is obtained by the automatically taught closing end position and the fine adjustment using the closing end position setting element, is specified to the control as the closing end position. This then controls the drive unit 30 between the end positions during operation and switches when it is reached the drive unit 30 in each end position. In addition, the final closing position is used to determine a reversing limit. For this purpose, the control unit 32 is designed in such a way that in a predetermined section before the closing end position - between the reversing limit and the final closing end position - an increase in force is not viewed as hitting an obstacle, but rather as reaching the end stop and is not used to switch off the force. The reversing limit must be set, for example, 40 mm before the final closing position.

The control unit 32 has a CPU and software in which the respective control processes are specified as instructions. For example, the operation start method can be carried out by software that is called when setting up the building completion drive device 16 and processed by the CPU. Control software is also provided for normal operation, which controls normal operation using the values for the end positions and the force thresholds learned in the learning runs.

In the Figures 9 and 10 Two further exemplary embodiments are given for the building closure 10 designed as a roller door 18. In the exemplary embodiment the Figure 9 the roller shutter 18 is designed as an external roller. The winding shaft 26 and the building closure drive device 16, which is designed as a roller door drive 24 and is connected to it, are attached inside a panel on the outside of the building above the door opening to be closed. The control unit 32 and an emergency unlocking device for decoupling the winding shaft from the roller shutter drive 24 in emergencies such as power outages are arranged within the building and are accordingly connected to the roller shutter drive 24 via connecting lines.

At the in Figure 10 In the exemplary embodiment shown, the roller door 18 is designed as an internal roller, with the roller door drive 24 and control unit 32 as well as the emergency release device 46 being arranged inside the building. Although the operating start procedure and the devices for carrying it out have been described using the example of a roller shutter, the techniques developed here are also applicable to other building closures in which problems with comfort and compliance with operational safety arise due to the arrangement and compression and pulling depending on different guides a power shutdown, applicable. For example, the building closure drive can also be a sliding gate leaf made up of several segments.
