Description

The invention relates to a building or enclosure completion position sensing apparatus for a building or enclosure completion drive and to a building or enclosure completion drive provided therewith.

Under buildings or enclosures are understood in particular doors and gates by means of which passages or passages in buildings or enclosures are closed. Accordingly, examples of building or fencing final drives in particular door drives or door drives. The building or enclosure end drives are used to drive a wing of the building or enclosure completion motor between an opening end position and a closing end position. As automatically driven building or enclosure closures, such terminations are subject to safety regulations such as the EU Machinery Directive. In particular, it should be ensured that no danger of jamming arises from such building or enclosure closures. In addition, the building or enclosure end drives on the one hand to safely approach the end positions, on the other hand, be switched off when reaching the end positions.

So that such functions can be achieved with simple means and yet comfortable and secure, is already in the EP 0 083 947 A1 It has been proposed to monitor an engine of the building or enclosure completion drive to its power requirement and to record the power demand at the respective position in a learning drive. The subsequent operation then takes place according to the recorded power requirement curve. Accordingly, the EP 0 083 947 A1 a building or enclosure completion position detection device in the form of a position encoder designed as an incremental encoder. When the motor shaft rotates, the incremental encoder emits pulses which are counted accordingly in a register. Such incremental encoders are relatively easy and inexpensive to produce; but they only provide a relative gate position signal. So is already in the EP 0 280 854 A1 an additional reference value transmitter has been proposed, which emits a signal when reaching a certain position of the wing of the building or enclosure closure, so as to specify a reference value for the position sensor.

After such a technology work most in practice offered gate drives and door operators.

From the WO 2010/009952 A1 is a trained as a direct drive or Wellentorantrieb building or enclosure end drive known in which a building or Einschlussungsabschlusspositionserfassungsvorrichtung is designed to detect the position of the wing of the connected building or Einbegrungsabschlusses as absolute encoder. For this purpose, for example, a potentiometer is provided which detects the angle of rotation of a Potentiometerwelle. The potentiometer shaft is connected by gearing to a motor shaft or an output shaft of the building or enclosure termination drive. This is done at the WO 2010/009952 A1 over a chain drive.

With such rotation angle sensors, an absolute encoder can be constructed, which provides a control of the building or enclosure completion drive with an absolute value of the position of the wing of the building or enclosure closure.

Such a technology not only works for door drives, but also for door drives.

To safely meet current and future safety regulations, many building or enclosure completion drives operate at a relatively slow speed. As a result, for example, a low-energy operation can be achieved. Efforts are therefore being made recently to improve building or enclosure finishing drives so that on the one hand they are very safe, on the other hand, the fastest possible opening or closing of the building or enclosure finishing wing is possible. Examples can be found in the DE 10 2013 106 959 A1 , of the DE 10 2014 119 734 A1 , of the DE 10 2015 000 582 A1 ,

In particular, it is desirable for the building or enclosure termination drive to drive the wing firmly into its end positions, but to react as sensitively as possible to an approach to an obstacle between the end positions.

The invention has for its object to further improve the corresponding functions of a building or enclosure completion drive in this regard.

To achieve this object, the invention provides a building or Einschlussungsabschlusspositionserfassungsvorrichtung with the features of claim 1 and provided therewith a building or enclosure completion drive according to the independent claim.

Advantageous embodiments are the subject of the dependent claims.

The invention provides a building or fencing completion position sensing apparatus for a building or enclosure completion drive for detecting a position of a building or fencing enclosure to be driven with the building or enclosure completion drive. The building or fencing completion position detecting apparatus includes a rotation angle sensor for detecting a rotation angle of a building or enclosure completion drive shaft of the building or enclosure completion drive to be ganged to the building or enclosure. The rotation angle sensor is connected to a gear transmission with the building or enclosure completion drive shaft having at least one gear unit connected to the rotation angle sensor and a gear unit connected to the building or enclosure completion drive shaft, the gear units meshing with each other. A first gear unit of the gear units has a first gear assembly and a second gear assembly, both of which mesh with the other, second gear unit. The first and the second tooth arrangement relative to one another are elastically rotatably connected to one another in such a way that teeth of the first tooth arrangement stand in an angle-offset manner with respect to teeth of the second tooth arrangement in the unloaded state.

It is preferable that the first gear unit is the gear unit connected to the rotation angle sensor. In an alternative embodiment, the first gear unit provided with the elastically rotatable tooth arrangements is the gear unit connected to the building or enclosure end drive shaft.

It is preferable that the first gear unit has a first gear on which the first gear arrangement is formed, and a second gear on which the second gear arrangement is formed, and an elastic connection between the first and the second gear.

It is preferred that the first and / or the second gear are formed of metal.

It is preferred that the first and / or the second gear are formed of steel.

It is preferred that the first and the second gear seated on a common gear shaft, wherein the first gear is fixedly connected to the shaft and the second gear is elastically connected to the gear shaft or to the first gear to elastically with respect to the gear shaft to to turn a rotation angle.

It is preferred that the first and the second gear are connected to each other via at least one elastomeric body.

It is preferred that the first tooth arrangement bear resiliently biased on tooth flanks of teeth of the second gear unit pointing in a first direction and the second tooth arrangement rest elastically prestressed on the other tooth flanks of the teeth of the second gear unit facing in the opposite direction.

It is preferred that the rotation angle sensor comprises an absolute value encoder and / or a rotary potentiometer.

In another aspect, the invention provides a building or enclosure completion drive comprising a building or enclosure termination drive shaft for ganged connection to a building or enclosing enclosure to be driven, and a building or enclosure completion position sensing device acting on the building or enclosure completion drive shaft of any of the previously discussed embodiments.

In a particularly preferred embodiment, the building or enclosure closing drive is designed as a door drive for driving a door and in particular designed as a direct drive or Torwellenantrieb for driving a door shaft of the door.

By means of the measures according to the invention, the position of a wing of a building or enclosure enclosed at a building or enclosure completion drive can be detected more accurately than previously. In particular, the building or fencing completion position sensing device may engage an output shaft of the building or enclosure termination drive. With the measures according to the invention, a play-free accurate rotational angle detection of the output shaft can be achieved.

Here, just a few tenths of a millimeter deviation can mean a deviation of the detected door position from the actual door position in the order of millimeters or even in the centimeter range.

However, if the position of the wing is detected more accurately, then you can do far better path-dependent safety features and comfort features. For example, reaching the end positions can be determined much more accurately. It can be a reversing limit - a point on the route just before an end position, from which an increase in a force is recognized as approaching an end position and not as an approach to an obstacle - set more precisely during learning trips. Accordingly, the wing can also be driven over a larger area in a faster operation without running the risk that the wing moves with great energy against the end positions.

This results in a considerable increase in comfort and safety.

The building or enclosure termination position sensing device is particularly useful with gate operators and more particularly with shaft door operators; However, use is also possible in door drives. Examples of particularly suitable building or enclosure finishing drives are the company publications "Instructions for installation, operation - WA shaft drives WA 400" of the Hörmann KG sales company with the imprint TR10E002-L RE / 03.2015 of March 2015 .

Reference is made expressly to the aforementioned references for further details of these building or enclosure completion drives.

An embodiment will be explained in more detail below with reference to the accompanying drawings. It shows:

1 a perspective view of a building or Einbegrungsabschlusses using the example of a sectional door with Torwelle and a building or enclosure closing drive on the example of a trained as a shaft drive gate drive, which is connected to the Torwelle and a building or Einschlussungsabschlusspositionserfassungvorrichtung in the form of designed as an absolute encoder position sensor;

2 a plan view of the building or enclosure completion position detecting device for the door drive of 1 in engagement with a worm wheel of the door drive;

3 a side view thereof;

4 a section through a gear unit at one of the building or enclosure completion position detecting devices of 2 and 3 ; and

5 a partial region of a sectional view along the line VV of 4 ,

In 1 is a building or enclosure 10 with a building or enclosure completion drive 12 for driving a grand piano 14 of the building or enclosure 10 shown.

In the example shown is as a building or enclosure 10 a goal - in particular a sectional door 16 - intended.

The sectional door 16 points as a wing 14 a sectional door leaf 18 on, in which several panels 20 articulated hinged together. Next, the gate has a door shaft 22 on, on the wing 14 is hinged gear.

In the example of the sectional door 16 is the door shaft 22 Part of a weight balance device 24 with a pretensioner 26 - Here a torsion spring - which is a counterforce to the weight of the wing 14 supplies.

The Torwelle 22 has rope drums 28 on, with the sectional door leaf 18 using ropes on the rope drums 28 connected. Next are guide rails 30 for guiding the sectional door leaf 16 shown.

The building or enclosure completion drive 12 is in the example shown to the door shaft 22 connected.

The building or enclosure completion drive 12 is here as a door drive 32 , more particularly as a shaft drive or direct drive, formed.

The door drive 32 has a motor unit 34 with an electric motor and a gear unit 36 with a self-locking worm gear and an output shaft 38 on, the to the Torwelle 22 connected.

The building or enclosure completion drive 12 has a building or enclosure finishing position detecting device 40 to capture the current position of the sash 14 of the building or enclosure 10 on.

The building or fencing completion position detecting device 40 in particular has a rotation angle sensor 42 on, the rotation angle of a shaft of the building or enclosure closing drive 12 detected and a dependent of the rotation angle signal as absolute encoder - or alternatively as a relative position sensor - provides.

The rotation angle sensor 42 is in particular with a potentiometer 44 equipped, which is adapted to one of a rotation angle of a Potentiometerwelle 46 to deliver dependent voltage.

The 2 to 5 Provide different views of the building or enclosure completion position sensing device 40 with the rotation angle sensor 42 As can be seen, the rotation angle sensor 42 by means of a gear transmission 48 to a building or enclosure completion drive shaft 50 - For example, the output shaft 38 - connected.

The gear transmission 48 has one with the rotation angle sensor 42 connected first gear unit 52 and one with the building or enclosure completion drive shaft 50 connected second gear unit 54 on. The gear units 52 . 54 comb each other. In the illustrated examples, the second gear unit 54 a worm wheel and the first gear unit 52 is designed as a screw.

The first gear unit 52 has a first tooth arrangement 56 and a second tooth arrangement 58 on. The first tooth arrangement is with the rotation angle sensor 42 firmly connected. The second tooth arrangement 58 is with the first order of teeth 56 by means of an elastic connection 60 connected so that the tooth arrangements 56 . 58 are rotationally elastic connected to each other at a certain angle so that they can rotate relative to each other by the certain angle.

The elastic connection 60 has, for example, a spring (not shown) or an elastomeric body 62 - rubber body - on.

The elastic connection 60 is formed such that the tooth arrangements 56 . 58 are arranged offset in the unloaded state by a predetermined angle to each other. Otherwise have the dental orders 56 . 58 a same tooth pitch and tooth shape. In use are - as in 5 shown - the teeth of the first and second tooth arrangement 56 . 58 under tension on teeth of the second gear unit 54 at. The teeth of the first tooth arrangement 56 engage in the one-way tooth flanks of the teeth of the first gear unit 52 on, and the teeth of the second tooth arrangement 58 engage the opposing other flanks of the teeth of the second gear unit 54 at. So is a play-free transmission between the first gear unit 52 and the second gear unit 54 possible.

In the illustrated embodiment, the tooth arrangements 56 . 58 at different portions of a split worm gear, which forms the screw arranged. A first gear half 64 is how in 4 shown rotatably with a shaft of the rotation angle sensor 42 connected. In the illustrated example, the first gear half 64 firmly with the potentiometer shaft 46 connected. The connection can be made by one-piece training or by material connection or by positive connection (eg by wedging). In the example shown sits a second gear half 66 relatively rotatable on the shaft of the rotation angle sensor 42 So for example the potentiometer shaft 46 , In the illustrated example, the second gear half 66 over the elastic connection 60 with the first gear half 64 connected, in other embodiments, the second gear half 66 through the elastic connection 60 also (additionally or alternatively) with the shaft of the rotation angle sensor 42 be connected.

In yet further embodiments (not shown), the tooth arrangements 56 . 58 be designed as different sprockets of a wheel, wherein the one sprocket via an elastic connection with the other sprocket - be it indirectly or directly - is connected.

Due to the elastic connection 60 become the teeth of the tooth arrangements 56 . 58 into the teeth of the second gear unit 54 clamped, so that a play-free transmission is possible, see 5 ,

As a result, the angle of rotation of the building or enclosure completion drive shaft 50 be accurately detected. Depending on the angle of rotation, a signal indicating the absolute position is supplied. In particular, if the building or enclosure completion drive shaft 50 directly or with as few intermediate elements as possible to the door shaft 22 is connected, so can the exact rotational angle position of the door shaft 22 and thus the exact position of the wing 14 on the drive or its controller.

Accurate position sensing allows the control to more accurately determine the positions of the end stops, reducing safety tolerances without sacrificing safety. It can be the safety zones just before the end stops shrink, in between is a faster operation and greater speed of the wing 14 possible.

When performing a learning trip, the position is also more accurate than previously determined; Thus, nominal curves for a force curve are shown in more detail; here too, safety tolerances can be reduced compared to previous solutions, since location errors are lower.

It is thus proposed a solution of a backlash-free torque transmission to the potentiometer shaft of a shaft drive. In particular, the solution presented here creates a play-free torque transmission by a particular embodiment of a rotation angle sensor gear. The rotation angle sensor gear has two gear halves, which by means of a vulcanized rubber element 68 are connected. A gear half 64 sits firmly on the rotation angle sensor shaft, the other gear half 66 is not connected to the rotation angle sensor shaft. The gear halves 64 . 66 are vulcanized to each other by a certain angle twisted. The twist angle is selected so that a gear half 64 on one flank and the other gear half 66 on the other flank of the thread of the output shaft 38 attacks.

This makes it possible to achieve a very accurate positioning of the wing in the end positions.

The building or enclosure completion position sensing apparatus described herein 40 is particularly well suited for door drives and more particularly for shaft drives. It can also be used in other building or enclosure finishing drives 12 , such as door drives, use.
