Description

The invention relates to a manufacturing method for producing an automatically driven door, which a door leaf, a door shaft, a door gear, by means of which the door leaf is connected to the door shaft such that the door shaft rotates upon movement of the door leaf and that the door leaf upon rotation of the door leaf Torwelle moved, and has a connected to the Torwelle for driving the same connected Wellentorantrieb. Furthermore, the invention relates to an operating method for operating a door produced by such a method. Finally, the invention relates to a gate system for producing such an automatically driven gate.

A manufacturing method for producing an automatically driven gate referred to in the preamble of claim 1 is known from WO 2010/009952 A1 known. Therein is described in particular a manufacturing method for producing a Wellentorantriebes for such a gate with Torwelle. The Wellentorantrieb is coupled to the door shaft, the Torwelle turn, for example, via a cable drum, is connected to the door leaf geared. To adapt to different drive tasks, the shaft drive is modular, with an output module being connected to a motor module which has all the important drive units, including an electric motor designed as a geared motor and an input shaft for a door drive transmission. The abrasion module has an output shaft. The input shaft and the output shaft of the drive gear are connected to each other via a Endloszugmittel. The endless traction mechanism thus formed is designed as a positive gear and thus slip-free. For example, toothed belt transmissions or-preferably-chain transmissions come into consideration. The different output modules have different sized gear wheels, so as to have a gear ratio of the integral
to set the drive gear formed at the Wellentorantrieb simply by selecting the appropriate output module.

The object of the invention is to improve a manufacturing method for producing an automatically driven door of the type mentioned in such a way that a particularly comfortable and safe operable gate can be created.

This object is achieved by a manufacturing method with the steps of claim 1. An operating method for a door produced by such a production method and a door system for carrying out the manufacturing method are the subject matter of the subsidiary claims.

Advantageous embodiments of the invention are the subject of the dependent claims.

• Bereitstellen und Montage des Tores mit Torwelle und Torgetriebe,
• Bereitstellen eines Wellentorantriebes, der einen Elektromotor und eine durch den Elektromotor über ein schlupffreies Antriebsgetriebe antreibbare Abtriebswelle aufweist, die an die Torwelle anschließbar ist, wobei das Antriebsgetriebe in der Antriebsgetriebeübersetzung stufenweise auswählbar oder einstellbar ist,
• Auswahl der Antriebsgetriebeübersetzung in Abhängigkeit von dem jeweiligen Torgetriebe derart, dass der Weg des Torblattes zumindest nahe dessen Schließendstellung pro Umdrehung des Elektromotors bei unterschiedlichen Torgetrieben derart im Wesentlichen konstant ist,
  1. a) dass er im Toleranzbereich von ± 25%, vorzugsweise von ± 15% um einen konstanten Richtwert liegt und/oder
  2. b) dass er im Toleranzbereich weniger als 40%, vorzugsweise von weniger als 36%, am meisten bevorzugt weniger als 30%, unterhalb eines konstanten Obergrenzen-Richtwerts liegt.

The invention provides a manufacturing method for producing an automatically driven door, which comprises a door leaf, a door shaft, a gate drive, by means of which the door leaf is connected to the door shaft such that the door shaft rotates upon movement of the door leaf and that the door leaf upon rotation of the door leaf Torwelle moves, and has a connected to the Torwelle for driving the same connected Wellentorantrieb, comprising the steps:

• Provision and installation of the gate with door shaft and door gear,
• Providing a shaft gate drive which has an electric motor and an output shaft which can be driven by the electric motor via a slip-free drive gear and which can be connected to the gate shaft, wherein the drive gear can be selected or set stepwise in the drive gear ratio,
• Selection of the drive gear ratio as a function of the respective gate drive such that the path of the door leaf is at least near its closing end position per revolution of the electric motor at different gate operations so substantially constant,
  1. a) that it lies within a tolerance range of ± 25%, preferably ± 15%, around a constant guide value and / or
  2. b) that it is within the tolerance range less than 40%, preferably less than 36%, most preferably less than 30%, below a constant upper limit guideline value.

The measure according to the invention, the overall gear ratio between the motor shaft and door leaf, at least in an interesting Torblattwegabschnitt, in particular at the closing end position, substantially constant.

It is customary to monitor the operation of a gate, inter alia, by means of monitoring an electric motor of the door drive. In particular, a power consumption of the electric motor, a voltage or a rotational speed of the motor shaft is monitored. It is also known in the market available gate drives to detect rotations of the motor shaft, for example via pulse generator and to use to control the door drive and the driven door. For this purpose, a learning run is usually carried out at the first start-up of the driven door to train the end positions of the door. The end positions then result from counter readings of a counter for counting the pulses of an incremental encoder.

Now, however, the different door drives are connected to very different gates in the entire state of the art. Gates provided with a door shaft have very different door ratios between the door shaft and the door leaf. These ratios also need to be adjusted from door to door, as most of these door shafts are used to balance the weight and corresponding changes in the door ratios serve to balance the door leaf weight as well as possible. This happens, for example, by different sized cable drums with which pull ropes or the like are wound upon rotation of the door shaft.

In the prior art, the gear ratio between the door drive and door leaf is thus not known for the door drive. It must therefore be carried out extensive adjustments, for example, if a specific Torblattwegstrecke to be detected. For this additional switches or the input of further parameters are necessary. For example, the door type and door fitting must be entered.

In particular, a so-called reversing limit must be taught separately. As a rule, the door drives are assigned monitoring devices for monitoring an undesired driveway to an obstacle. However, a driveway against a closing end position forming stop should not be recognized as such obstacle. It is therefore known to activate such monitoring devices at the reversing limit in the closing direction shortly before the closing end position. In relevant safety standards, a maximum distance of the reversing limit to the closing end position of e.g. 50 mm, mandatory, which must not be exceeded. This reversing limit is taught in some on-market door operators after assembly, for example, by placing the driven door leaf on a test specimen, of e.g. 50 mm height, can be raised. In practice, a folding rule of 30 to 35 mm in height is often used; and the reversing limit is taught to the stop when driving on this yardstick. As a result, you can be sure that you can safely comply with the desired maximum distance of 50 mm. If one did not specify a reversing limit, there would be the danger that the door leaf would not move correctly into the closing end position and not close the door properly, as previously disclosed e.g. a closing edge safety responds. This learning of the reversing limit is complex and must be trained. In a preferred embodiment of the invention, this learning the reversing limit is made redundant.

With the measure according to the invention, a drive gear ratio in the shaft gate drive is adapted to the respective gear shift ratio, so that a total ratio between motor shaft and door leaf movement remains substantially the same within certain tolerance limits, at least in a gate leaf path region of interest. In this respect, one can assume in this Torblattwegbereich from the outset, the transmission ratio between the motor shaft and Torblattbewegung as about known. This makes it much easier to control and monitor the operation of the door thus produced.

Many door fittings have door gears whose door gear ratio is not constant; For example, they are provided with conically shaped rope drums. If a door drive with a door drive gearbox is connected to such a door drive, the overall ratio does not remain the same over the entire Torblattweg between Schließendestellung and opening end position. For many control and monitoring tasks, however, only a specific part of the Torweges path is interesting, in particular a partial area, which is located before the Schließendstellung.

This has particular advantages for setting the aforementioned Reversiergrenze according to DIN 13241. An automatic gate should be provided with a monitoring device that detects a collision with an obstacle and reverses the drive. In the area of the final closing position, however, such monitoring is a hindrance if the door leaf is to travel safely against the closing stop. If the monitoring device also remains active in the closing end position, approaching the closing end position would be recognized as an obstacle and the drive would stop or retract. Therefore, a reversing limit is already taught when installed on the market after installation gate drive over which a monitoring device for detecting the approach to an obstacle is inactivated. According to the above-mentioned standard, this reversing limit may not be more than 50 mm before the closing end position. On the other hand, the reversing limit should be sufficiently far away from the closing end position so that a safe retraction against the closing stop can take place even if the stored position of the closing end position differs from the actual position without an obstacle being detected incorrectly. If one now knows the overall transmission ratio between the engine and the door leaf movement in the area of the closing end position, the reversing limit can be calculated automatically simply from the closing end position on the basis of the engine revolutions. Therefore, in a preferred embodiment of the invention, the area of the Torblattweges directly at the closing end position interesting.

The manufacturing method according to the invention can be carried out in a particularly simple manner with a shaft gate drive, which has a motor module and an output module selected for adapting the drive gear ratio from an assortment of output modules. A preferred Wellentorantrieb the type in question is in the WO 2010/009952 shown and explained in more detail. Reference is made to this document for further details.

According to the invention, the door drive is selected from a group of predetermined door drives, each of which has predetermined different door shaft ratios between door leaf movements and rotation of the door shaft.

The manufacturing method is then particularly advantageous feasible, if now the just mentioned modular Wellentorantrieb is used and each of these predetermined gate gear a specific output module is assigned from the group of output modules. By way of example, the door manufacturer supplies the appropriate shaft gate drive with a suitably selected output module in accordance with the respective door with gate drive.

As a rule, gates with completely different door fittings are available from each door manufacturer. For example, sectional doors are designed as ceiling sectional doors, which are laid down horizontally below a ceiling in the opened state and which pass through an arcuate guide between the open state and the closed state. The same door leaf can also be used in a vertical guide simply as a lifting gate led vertically upwards. Depending on the space above the door opening to be closed, a door fitting with a door leaf guide, which goes through a large arc, or a low-fall fitting can be supplied. Depending on the Torblattgröße and Torblattgewicht certain Torgetriebeübersetzungen between a provided for weight balance with torsion spring door shaft and the door leaf are provided in each gate fitting.

With such a gate system with different gate fittings, the manufacturing process is particularly advantageous and also for less qualified assembly forces simply feasible that for each gate fitting a certain drive gear ratio, for example by providing the appropriate drive gear or the appropriate above-mentioned output module is provided.

A setting of the aforementioned Reversiergrenze is particularly easy to do, if from the outset, a fixed ratio between Motor shaft and door leaf movement can be assumed, as is the case with a door produced by the method of manufacture proposed here.

• Einlernen von Torendstellungen durch Zählen von Impulsen eines die Drehung des Elektromotors erfassenden Impulsgebers,
• Berechnen einer vorgegebenen Torblattwegstrecke ausgehend von einer der Schließendlage anhand der Impulszahl und des oben genannten maximalen Obergrenzen-Richtwert für das Gesamtübersetzungsverhältnis,
• Aktivieren oder Aktivhalten einer Sicherungseinrichtung zur Erfassung, ob das Tor gegen auf ein Hindernis auffährt, wenn anhand der Impulszahl festgestellt wird, dass sich das Torblatt außerhalb dieser Torblattwegstrecke bewegt,
• Deaktivieren oder Inaktivhalten der Sicherungseinrichtung, wenn anhand der Impulszahl festgestellt wird, dass sich das Torblatt innerhalb der Torblattwegstrecke bewegt oder befindet.

Thus, according to a further aspect, the invention provides an operating method for operating a door produced by the method according to one of the preceding claims with the steps:

• Teaching Torendstellungen by counting pulses of a rotation of the electric motor detected pulser,
• Calculating a predetermined gate blade travel distance from one of the closing end positions on the basis of the pulse number and the above-mentioned maximum upper limit standard value for the overall transmission ratio,
• Activating or maintaining a safety device to detect whether the door is approaching an obstacle when it is determined from the number of pulses that the door leaf moves outside this door leaf travel,
• Disabling or inactivation of the safety device when it is determined by the number of pulses that the door leaf moves or is located within the Torblattwegstrecke.

If one assumes a maximum upper limit guideline value, which is fallen below by each driven gate of the gate system, for calculating the reversing limit, then it is ensured that the actually calculated reversing limit for each gate remains below the prescribed maximum value.

1. a) dass er im Toleranzbereich von ± 25%, vorzugsweise von ± 15% um einen konstanten Richtwert liegt und/oder
2. b) dass er im Toleranzbereich weniger als 40%, vorzugsweise von weniger als 36%, am meisten bevorzugt weniger als 30%, unterhalb eines konstanten Obergrenzen-Richtwerts liegt.

According to a further aspect, the invention provides a gate system for producing an automatically driven gate, comprising: a group of gate types, each having a door leaf, a gate shaft and a respective different gate drive, wherein the gate leaf is coupled to the gate shaft by means of the gate drive such that the door leaf moves during rotation of the door shaft and the door shaft rotates upon movement of the door leaf, and
a group of Wellentorantrieben, each formed with an electric motor, a slip-free drive gear and an output shaft, wherein the output shaft is designed to be connected to the Torwelle and driven by the electric motor via the drive gear, wherein the drive gear is formed differently in the different Wellentorantrieben, one to provide different drive gear ratio between electric motor and output shaft,
wherein each type of door a particular Wellentorantrieb from the group of Wellentorantrieben is assigned such that in the vicinity of the Schließendlage, in particular within a distance of 50 mm from the Schließendlage, the path of the door leaf per revolution of the electric motor at different Torgetrieben is substantially constant,

1. a) that it lies within a tolerance range of ± 25%, preferably ± 15%, around a constant guide value and / or
2. b) that it is within the tolerance range less than 40%, preferably less than 36%, most preferably less than 30%, below a constant upper limit guideline value.

Such a gate system particularly preferably has a shaft gate drive, which according to the teaching of the WO 2010/009952 A1 is made.

More preferably, a control for controlling the operation of the door provided with this gate system is provided. Since the transmission ratio between the motor shaft and Torblattbewegung is approximately known in such a goal, the controller can easily calculate from the motor movement, the covered Torblattstrecke. This can be used for a variety of control tasks.

The control does not need to be adapted separately for different Tortyen.

In a particularly preferred embodiment, the door system comprises a controller for controlling the operation of the automatically driven door, wherein the controller is formed
for teaching gate end positions by counting pulses of a pulse generator detecting the rotation of the electric motor,
for calculating a predetermined gate blade travel starting from the closing end position on the basis of the pulse number and the maximum upper limit standard value for the overall transmission, for activating or keeping active Securing device for detecting whether the gate is approaching an obstacle when it is determined from the number of pulses that the door leaf moves outside of the door leaf travel distance,
and for deactivating or keeping inactive the securing device, if it is determined on the basis of the number of pulses, that the door leaf moves or is located within the Torblattwegstrecke.

Such a control is suitable for automatically determining the reversing limit simply when learning the lower closing limit.

In one embodiment, a door system has at least three different door types, for example in the form of sectional doors, each with different door fittings. Each sectional door fitting has a specific cable drum with specific diameter. Thus, there is a door gear with a special gear ratio in each of the sectional doors. In a Wellentorantrieb, as he with the method of the WO 2010/009952 A1 is prepared, you can now provide for each specific gear ratio of the gate a specific output module, such as a specific chain adapter, for the Wellentorantrieb to be used. As a result, the door driven by such a shaft gate drive has a total gear ratio of the door drive and the door leaf, which is essentially the same and is within a certain tolerance range around a guideline value.

This has the following safety advantage in particular. Automatically powered doors are considered machines according to machine safety guidelines. For example, should therefore be respected for such goals a certain distance within which safety devices, such as a closing edge safety device are active. So far, this has been accomplished in particular by specifically programming a controller for the door drive during the commissioning of the automatically driven gate. But if one specifies a substantially constant overall gear ratio, the controller knows this total gear ratio at least approximately. The controller can now calculate itself based on a tapped off at the motor shaft pulse number, which route leaves the door leaf.

It is thus possible, for example starting from the learned lower closed position, to set the corresponding distance to be secured.

In a preferred embodiment, a small gear is used for a smaller gear ratio, for a large rope drum diameter, a large gear is used. As a result, each revolution on the engine means a certain distance at the gate. The deviations are always minimal.

In FIG. 1 an automatically driven gate 10 with a door leaf 12, a frame 14, and a door shaft 16, a door gear 18 and a shaft gate drive 20 is shown. In the gate 10 is a sectional door with a gate as a door leaf, which is constructed of individual mutually pivotally hinged together panels 22.

The door shaft 16 and the door gear 18 are part of a predetermined first door fitting 24, by means of which the door leaf 12 is articulated on the frame 14 articulated. In addition to the door shaft 16 and the gate drive 18, the first door fitting 24 also has a guide 26 for guiding the door leaf 12. The guide 26 has guide rails 28, are guided within the rollers 30 which are mounted mounted on the individual panels 22.

The Torwelle 16 is part of a weight balancer 32 for balancing the weight of the door leaf 12 and has a torsion spring 34 which is relaxed or tensioned when turning the Torwelle 16.

The door leaf 12 is connected via the gate drive 18 to the door shaft 16 such that the door shaft 16 rotates upon movement of the door leaf and, conversely, the door leaf 12 moves upon rotation of the door shaft 16.

The door shaft 12 has at each end a Zugmittelerfassungseinrichtung for detecting a traction means of the gate operation 18. For example, the Torwelle 12 at the ends in each case a cable drum 36, on which a cable 40 is wound up. One end of the traction means - e.g. - Rope 40 is connected in a manner not shown to the door leaf 12 so as to open the door leaf 12 by rotation of the door shaft 16 upon detection of the traction means by the Zugmittelerfassungseinrichtung, e.g. by winding the rope 40 on the cable drum 36 to pull up.

At the in FIG. 1 shown first door fitting 24 is a gate fitting, which is also referred to below as a normal fitting N1. In this normal fitting, the guide has a horizontal course 42 approximately at the height of the door shaft 16. An arcuate course 44, which forms a transition between the horizontal course 42 and a vertical course 46, is correspondingly arranged at least partially below the door shaft 16. The roller 30 of the uppermost panel 22 is fixed to a pivotable roller holder 48 which, despite the low arcuate curve 44, allows complete vertical alignment of the uppermost panel 22.

The Wellentorantrieb 20 is one of a in FIG. 2 illustrated group of shaft drives WA300A, WA300B, WA300C and WA300D selected shaft gate operator. All these Wellentorantriebe are modular and each have an identically constructed engine module 50 and one of four output modules A, B, C, D. The detailed structure of these Wellentorantriebe 20 is more detailed in the WO 2010/009952 A1 which is expressly referred to for further details and incorporated herein by reference.

Accordingly, the Wellentorantriebe WA300A, WA300B, WA300C and WA300D due to the different output modules A, B, C, D respectively different drive gear 52A, 52B, 52C and 52D, each with different drive gear ratios i.

For example, the drive gear 52A, 52B, 52C, 52D chain transmission, the output modules A, B, C, D are chain adapter, each with a different sized sprocket on the output shaft 54. As a result, the drive gears 52A, 52B, 52C, 52D have different drive gear ratios i.

At the in FIG. 1 shown first gate fitting 24 - the normal fitting N1 - the second Wellentorantrieb WA300B with the second drive gear 52B is used with a drive gear ratio i = 2.6.

The other shaft drives WA300A, WA300C, WA300D are used for other gates and other gate fittings, as in the Figures 3 and 4 and is explained in the following Table 1.

FIG. 3 shows a schematic representation of the first door fitting 24 with the associated second Wellentorantrieb WA300B, and a schematic representation of a second Torbeschlages 56 with fully vertical guides 26 and overlying indicated Torwelle 16, wherein at a gate height RM (abbreviation for grid height) less than or equal to 2500mm the is associated with the third Wellentorantrieb WA300C and wherein at a gate height RM greater than 2500mm, the fourth Wellentorantrieb WA300D is assigned. In this second door fitting 56 depending on the door height RM rope drums 36 are used with different diameters, so as to better compensate for the higher Torblattgewicht for larger door leaves 12 can. The second door fitting 56 is also referred to as a vertical fitting V6.

In FIG. 4 is still a third gate fitting 58 shown, wherein in different embodiments of this third gate impact 58 either the third Wellentorantrieb WA300C or the fourth Wellentorantrieb WA300D is assigned. In this third door fitting 58 is, for example, a higher runner rail H4 with overhead door shaft 16 or a higher run Track fitting HU4 with lower Torwelle 16 (not shown). In these third gate fittings 58, the arcuate course 44 of the guide 26 is guided higher, so that the door leaf 12 is first a piece vertically upwards and then only arched out. Here, the third shaft drive WA300C is used when the difference between the rail height LH minus the door height RM is less than or equal to 1250mm. The fourth shaft drive WA300D is used if the difference between the track height LH minus the gate height RM is greater than 1250mm. Also in this third door fittings 58, different cable drums 36 having different diameters are used in each of these two cases, so that the respective door gears 18 used have a different door gear ratio.

Fig. 5 shows the installation of the third Wellentorantriebs WA300C as Wellentorantrieb 20 at the gate provided with the third gate fitting 58. Here, corresponding parts are the same reference numerals as in Fig. 1 used.

How out Fig. 5 it can be seen that the diameter of the cable drums 36 is not necessarily constant; Rather, many cable drums 36 are conically shaped to optimally adjust the weight balance force of the torsion spring 34 to the gate weight acting in the respective door leaf position. Therefore, it is interesting in the embodiments shown here, in the different types of doors an approximately constant total translation between revolutions of the electric motor and the Torblattbewegung in a certain section of the Torblattweges to know beforehand. In the exemplary embodiments present here, as an example for this particular route area, within which the overall transmission ratio remains approximately the same, the section of the track immediately following the closing end position is selected. The translations of the door drive are selected so that in a range of a Torblattwegstrecke of at least 50 mm Torblattweg from the Schließendstellung from this overall ratio remains approximately the same.

In FIG. 6 is still a fourth door fitting 60 indicated with the associated shaft door drive 20. This fourth door fitting 60 is a so-called low-fall fitting L1, an example of a gate with such a low-fall fitting in the FIGS. 7 . 8 and 9 is shown, the different ways of installing the Wellentorantriebes 20 show. Again, the same reference numerals for corresponding parts as in Fig. 1 used.

This fourth door fitting 60 has an in FIG. 6 indicated torsion spring shaft with torsion springs 34 and (not shown) cable drums, wherein a wound thereon rope 40, as in FIG. 8 shown connected to one end of a chain 62, whose other end is connected to the door leaf 12. The gate shaft 16, to which the shaft gate drive 20 is to be connected, is designed here as a short shaft piece with a chain locking region 66 engaging positively in this chain 62. To the thus formed with chain 62 and shaft piece 64 Torgetriebe 18 is, as in FIG. 6 shown to connect the first shaft drive WA300A with very small drive gear ratio i.

An overview of the drive gear ratios i for the individual shaft drives WA300A, WA300B, WA300C, WA300D as well as the door fittings assigned to each of these shaft drives is given in Table 1, which reproduces the technical data of these individual types of shaft drive. Table 1: Specifications of shaft gate drive types shaft drive WA 300 A WA 300 B WA 300 C WA 300 D Kettenradübersetzung i = 1.3 i = 2.6 i = 3.6 i = 5.3 Input speed 40-64 min ^-1 20-32 min ^-1 15-24 min ^-1 10-16 min ^-1 fitting L1 low-drop gear N1 normal fitting H4 Higher level track fitting LH - RM ≤ 1,250 mm H4 Higher level track fitting LH - RM> 1,250 mm V6 vertical fitting RM ≤ 2.500 mm V6 vertical fitting RM> 2,500 mm Gate opening speed Max. 0.18 m / s operating voltage 230V 1 AC frequency 50 Hz engine power 0.30 kW 0.30 kW 0.30 kW 0.30 kW duty Max. 12 cycles per hour: operating mode S3 = 20% ED rated torque 15 Nm 30 Nm 45 Nm 60 Nm Shaft diameter 25 mm 40 mm with spring protection IP 65 permissible ambient temperature -20 ° C to +60 ° C connection Plug / screw terminals and system sockets Airborne noise Max. 70 dB (A) additional fittings

Through this assignment, a specific drive gear 52A, 52B, 52C, 52D is used for each of the different gate fittings 24, 56, 58, 60. Differing in the individual door fittings 56, 58 due to other Tormaßen and therefore to be changed diameter of the cable drum 36, the Torgetriebeübersetzungen the door gear 18 within the above-mentioned Torblattwegstrecke of 50 mm before the closing end position, are also different drive gear 52C or 52D (in the third Shaft gate drive WA300C or the fourth shaft drive WA300D) to use.

Translation of the output modules designed as a chain adapter A, B, C, D is shown in Table 2. The speeds of a conventional Wellentorantriebes WA400, as he has been previously used, set to the speeds of the Wellentorantriebe 20 from the group of Wellentorantrieben WA300. In the far right last four columns, the door leaf displacement per revolution of the motor shaft is then given in millimeters, in each case by fitting and shaft gate drive, and the number of revolutions at 50 mm Torblattweg and the Torblattgeschwindigkeiten at two adjustable speeds of the motor of the motor module 50 are shown ,

It can be seen that by selecting the appropriate drive gear 52A, 52B, 52C, 52D to the respective gate fitting and thus to the translation of the respective gate 18, a Torblattweg of about 2mm per revolution of the motor shaft can be achieved as a guide. Larger deviations arise only in borderline cases, whereby here too the deviation amounts to less than 25% to this reference value of 2mm per revolution of the motor shaft. It also turns out that for a distance of 50mm Torblattweg approximately 25 revolutions of the motor shaft are to be performed.

In this respect, the overall gear ratio between the motor shaft of the electric motor of the motor module 50 and the path of the door leaf 12 remains approximately the same within the respective Torblattwegstrecke interest. This facilitates the monitoring and control of the automatically driven gate 10, since the actually performed in the Torblattwegstrecke interest Torblattbewegung without separately entering the gear ratio is immediately recognizable on the motor shaft.

In a known manner, the movement of the motor shaft on the electric motor itself can be detected. For this purpose, a Hall sender is provided in the electric motor, which detects the rotation of the motor shaft as a pulse generator. An example of a correspondingly used geared motor with Hall sensor is more precisely in the not previously published German patent application DE 10 2010 050 827.6 shown and explained in more detail. Reference is directed to this patent application for further details, which is incorporated by reference into the present disclosure.

In the FIGS. 10 to 12 is still a security device 70 for detecting a risk that the door leaf 12 runs up against an obstacle, represented. The securing device 70 is designed, for example, as a closing edge safety 72. The closing edge safety device 72 has a flexible profile 76 to be fastened to the lower closing edge 74 of the door leaf 12, wherein a light barrier 78 is provided for detecting a compression of this flexible profile 76. If such a compression is detected by the light barrier, a signal is sent to a controller, not shown, which immediately puts the motor of the motor module 50 out of operation and can turn a few times in the opposite direction.

However, if the door leaf moves into the closing end position, then this retraction should also be possible with a certain force, so that the closing end position is reliably achieved and the door leaf is locked. Therefore, shortly before the closing end position, the closing edge safety device 70 should no longer be active. The door leaf travel distance before the closing end position, within which no shutdown and no reversing takes place, should be a maximum of 50 mm, so that trapped obstacles greater than 50 mm can be reliably detected. The limit from which reversing no longer occurs is often called the reversing limit.

The controller is designed such that it shuts off this securing device 70 in the course of a closing movement when the reversing limit is exceeded. This reversing limit of, for example, max. 50 mm from the lower close end position is reliably calculated by the controller based on the fixed gear ratio solely by the motor shaft rotation since the gear ratio to the door leaf path in this door leaf lane region is approximately set. Simultaneous teach-in of the reversing limit together with teaching the closing end position is easily programmable. For this purpose, only the reference value for the gear ratio is used. In Table 2, for example, the number of revolutions for this 50 mm Torblattweg is given for each example. This is for all at more than 20 engine revolutions. Therefore, if you set the reversing limit such that they at about 20 engine revolutions before the close end position is defined, then this reversing limit is given sufficiently accurately for all gates without having to separately program or teach them.

This application is an example of the fact that the prior knowledge of the translation between Torblattweg and motor rotation has particular advantages for the control and monitoring of the gate 10.

The invention thus provides, in particular, a production method for producing an automatically driven gate (10), which has a door leaf (12), a door shaft (16), a gate drive (18), by means of which the door leaf (12) is attached to the door shaft (16). is connected, that the gate shaft (16) rotates upon movement of the door leaf and that the door leaf moves upon rotation of the Torwelle (16), and having a to the Torwelle (16) for driving the same connected Wellentorantrieb (20), with the steps :
Providing and assembling the door with the door shaft (16) and gate drive (18), providing a shaft door drive (20) having an electric motor and an output shaft (54) drivable by the electric motor via a slip-free drive gear (52A, 52B, 52C, 52D) , which is connectable to the Torwelle, wherein the drive gear (52A, 52B, 52C, 52D) in the drive gear ratio (i) is selectable stepwise adjustable selection of the drive gear ratio (i) in response to the respective door gear (18) such that at least near the closing end of the path of the door leaf (12) per revolution of the electric motor at different gate operations (18) is so substantially constant that it is in the tolerance range of ± 25%, preferably ± 15% by a constant guide value or in one predetermined tolerance value is below a maximum constant upper limit reference value.

In Table 2, among other H-fittings for higher overhead sectional doors and V-fittings for pure lift gates (often also have a sectional door leaf, but which is guided purely vertically) are listed. These gate fittings have conical cable drums. Accordingly, one can not speak of a fixed gear ratio for the door gear. The higher-level door fittings (H-fittings) have a cylindrical cable drum area and a conical cable drum area. For these fittings, a fixed gear ratio applies only to the cylindrical part of the cable drum, which is used in the area of the Torblattweges for winding when the door leaf leaves a vertical guide rail and the top panel goes into a horizontal movement. The vertical fittings (V fittings, pure lift gate), there is no fixed gear ratio.

In these Torbeschlägen with over the Torblattweg changing gear ratio, the idea of the known translation is particularly interesting for a Torblattwegstrecke, which terminates at one end by the closing end position and extending from this at least 50 mm in the direction of the opening end position. Within this area of the door leaf travel path, the reversing limit should be defined, which according to DIN EN 13241 may be a maximum of 50 mm away from the closing end position.

The drive ratios are chosen so that exactly in the range of the door position "TOR CLOSE" almost identical overall gear ratios prevail when the cable drum is selected with the maximum cable drum diameter. For the H-fittings the rope drum with the maximum cable drum diameter is used, if it is a gate with maximum height guidance. For the V-fittings, the rope drum with maximum rope drum diameter is used if it is a gate with the maximum possible gate height. For low-lift gates, H-fittings with a smaller drum diameter are used, and for lift gates with smaller door heights, a V-fitting with a smaller drum diameter is used. If, therefore, the height guide for H-fittings or the door height for V-fittings is lower, then the total transmission ratio determined for the maximum cable drum diameter is less appropriate for these door fittings, even with the door position "TOR CLOSED". Will therefore the Reversing limit determined on the basis of the predetermined total ratio, this shifts at deviating overall ratio. However, if the guideline value is calculated for the largest rope drum diameter, the reversing limit always shifts in the safe direction to the "TOR CLOSE" position compared with the reversing limit calculated at the reference value, since the rope drum diameter can only become smaller.
For example, in the example of Table 2, the reversing limit would be set to 20 revolutions from the "gate closed" position in the opening direction. All listed doors require more than 20 turns to drive through 50 mm of door travel. Therefore, this ensures that when learning the position "TOR CLOSE" without further teach-in or programming automatically a calculated reversing limit is set, which is smaller than 50 mm.

From Table 2 it can be seen that all the total ratios, as measured in the Torblattweg in mm per revolution of the engine, in a tolerance range of 40% and most of the total ratios in a tolerance range of 30% below a maximum upper limit of 2.5 mm / Turn lie.

For gate fittings that provide over the entire Torblattweg an approximately equal ratio of Torgetriebes such. B. the in Fig. 1 shown normal fitting and the in the Fig. 7 . 8 and 9 shown fitting can be determined from the outset over the entire Torblattweg the position of the door leaf on the basis of the number of revolutions of the electric motor without further programming at the set by selecting the appropriate gear stage in the door drive fixed gear ratio. This can be used in a gate system, which uses only such fittings, except for the calculation and presetting of the reversing limit for other control and monitoring tasks.
