Description

METHOD FOR PRODUCING A GATE ENGINE;

DOOR DRIVE SYSTEM FOR CARRYING OUT THIS PROCEDURE

AS WELL AS USING A DOOR DRIVE MANUFACTURED THEREFOR

The invention relates to a method for producing a door drive, a door drive system, by means of which a door drive can be produced, and provided with a door drive thus produced gate.

Door drives usually have an electric motor, which is designed as a geared motor. The output shaft of the geared motor can be geared to connect with a gate so that when turning the geared motor, the gate between its opening end position and its Schließendstellung is movable.

The common types of door drive are the so-called drag drives or the direct drives or shaft door drives. In the trailing drives, a door leaf is coupled to a guided inside a guide rail driver. Often, however, doors also have a door shaft, which is coupled to the door in such a manner that the door shaft rotates when the door leaf moves. Such Torwellen are often designed as part of a weight balancing device as a torsion spring shaft. The Wellentorantriebe are designed such that they can be connected to such a door shaft and drive this door shaft by motor. By driving the door shaft then the door leaf is moved. In this way, you can save the assembly of far into the space to be closed by the door to be closed door drive guide rails, as provided for traction drives. Wellentorantriebe are often used on sectional doors of halls or the like, but also on garage doors of underground garages, where the installation of a towed drive is difficult. Depending on local conditions, however, it may be difficult to couple the shaft drive to a door shaft. Often there is not enough space at the end of the door shaft to still arrange the entire door drive with drive housing in the axial direction next to the door shaft.

For such cases has been provided for Wellentorantriebe separate torque transmitting devices, which are formed for example as a chain transmission with its own torque transmission housing. This can be used to counter installation situations in which the door drive can not be coupled directly to the door shaft. However, even with such torque transmission devices only a limited adaptation possible. In particular, a fixed radial distance between the input shaft and output shaft of the torque transmitting device is provided.

The object of the invention is to provide a method and a door drive system for producing a door drive, with the gate drives are produced in a simple and cost-effective manner, which are better adaptable to each installation situations and thus easier to mount on a given gate with special installation situations.

This object is achieved by a method or a door drive system having the features of the independent patent claims.

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

A method for producing a gate driven by a door, in which a gate drive produced by the method or with the door drive system is used, is the subject of the further independent claim. In most known Torantrieben the electric motor is mounted on a base structure, in particular a base plate, which can then be fixedly mounted in a drive housing or as part of the drive housing. On this base plate also other elements of the door drive, in particular electrical units, such as interference, lighting, power electronics or the like, can be attached.

According to the invention, a first base structure part and a second base structure part are now provided instead of a single base structure such as a single base plate.

The first basic structural part carries the motor and thus a motor shaft. Here, according to preferred embodiments, the other elements such as an electric unit or a decoupling device or the like may be provided.

This first basic structure part is always produced the same in the production of the door drive in series, especially in mass production, which saves considerable production costs in terms of the common part strategy. By contrast, the second basic structural part is modular. There are a plurality of different second base structure parts from which a suitable one for the construction of the desired door drive is selected and connected to the first base structure part.

For this purpose, the different second basic structural parts are provided with a fastening interface constructed essentially the same, namely fitting to the first basic structural part.

Preferably, the second base structure parts are designed as drive modules. For this purpose, a bearing for an output shaft is provided at the different second base structure parts. The differences between the second basic structural parts may, for example, in a radial and / or axial Distance of the bearing of the output shaft from the mounting interface and / or in a transmission ratio for the output shaft and / or in a different embodiment of a shaft connection for connecting different Torwellen lie. These differences are only mentioned as examples; There may also be other differences, such as the axial position of a coupling element for coupling the output shaft to a door shaft or the like between the different output modules.

In the manufacture of the door drive, a suitably selected base plate part is thus attached to the respectively identically designed first base plate part with the motor.

This can create using a maximum number of equal parts differently shaped door drives, which are designed for different installation situations and / or for different balance of power at the gate.

In particular, it is thus possible to avoid the use of an additional torque transmission device between the door drive and a door shaft. This makes it possible to avoid the manufacturing and assembly costs as well as the logistic effort for an additional torque transmission device.

A simple change of the transmission ratio by replacing the second base structure part is possible if a traction mechanism - in particular belt, timing belt or chain drive - or other wheel gear, such as gear transmission, is used for a geared connection between the motor shaft and the output shaft of the door drive. The different second base structure parts then preferably gear wheels, such as traction wheels, with different diameters, which at a correspondingly constant output on the Motor shaft of the first base plate part provide for a different transmission ratio.

In a preferred embodiment of the invention, a first and a second base plate part are used as basic structural parts, so as to form a plate-shaped basic structure on which both the engine with motor shaft and the output shaft are mounted with gearbox between the motor shaft and the output shaft. However, the invention is not limited to the use of such plate-shaped elements for forming a base structure or support structure. More generally, a basic structure of the door drive, on which the torque-transmitting parts are mounted and absorb the forces, divided into at least two parts, namely in a first base structure part and a second base structure part. The first basic structure part is the same for all door drives of the door drive system. In the manufacture of the door drive, however, the second base structure part as an exchangeable Abtriebsmodu! selected from an assortment of different second basic structural parts. For this purpose, the different second base structure parts of a respective similar Festigungsschnittstelle are provided to be attached to corresponding mounting structures of the first base structure part.

The attachment between the base structure parts is preferably carried out detachably, for example by screws.

In particular, when using a traction mechanism, such as a chain transmission, the base structure parts with selectable adjustable relative position are fastened to each other. As a result, the traction means can be tensioned solely by displacing the basic structural parts relative to one another and subsequent fastening.

In order to absorb torque shocks and to ensure a smooth running, the attachment is preferably not rigid, but designed to be elastically movable, so that the respectively selected second base structure part in elastic to a certain extent, relative to the second base structure part can move.

As already mentioned above, it is particularly preferred that the basic structural parts are designed as base plate parts. This has advantages in the production. The base structure parts can be easily punched as plate parts and formed by cold forming. Even molds are conceivable and possible. A plate shape can be carried out particularly rigid, in particular by stiffening ribs or beveled or otherwise as angled edge regions. Furthermore, such a plate part can be used and used as the housing wall of a drive housing. For this purpose, it is also preferred if the second base structure part, in particular a second base plate part, projects radially around the output shaft at the peripheral area of the output shaft. In this way, a cover can also be placed over a trained as part of the output shaft gear (for example sprocket) and so to protect the gear against interference from the outside and / or against contamination.

An uncoupling device for emergency releases in the event of accidents is preferably arranged on the first base structure part and thus participates in the same part strategy. The first base structure part can thus be produced inexpensively together with the coupling device in mass production, for example on the assembly line.

On the second base structure part, a position sensor is preferably also provided, which measures the position of the motor shaft and thus determines the position of the door coupled therein. This position sensor is preferably designed as an absolute encoder. For this purpose, for example, a rotation angle sensor - in particular with itself via a Hall sensor rotating magnet - may be provided. Thus, to learn a Torlaufes with appropriate end points of the door movement, which are then approached controlled, only once after installation a reference run to be performed. In a decoupling - for example, in emergencies or in Power failure - but the once learned gate position does not have to match the actual goal position. It is therefore preferably - also preferably associated with the first base structure part - a detection element for detecting a Entkupplungsvorganges provided.

According to a particularly preferred embodiment of the invention, the position sensor is positively connected to the output shaft and / or the transmission in engagement. In one embodiment of the transmission as positive traction mechanism of the position sensor or in addition to the above-mentioned, acting on the motor shaft position sensor provided further position sensor preferably with the traction means (eg chain or timing belt) or with the output gear (eg sprocket) in positive engagement or form-fitting geared to a drive wheel of the transmission (eg sprocket) coupled. The decoupling device is preferably provided between the motor shaft and the drive wheel. The entire transmission thus continues to rotate even when the engine is decoupled. Therefore, even in the decoupled state, the current position of the driven Torwelle and thus the gate position can be detected. A reference run after a decoupling process, as mentioned above, is therefore unnecessary. Also, the above-mentioned detection element for detecting a decoupling operation can be omitted.

The second base structure part, in particular the second base plate part, further preferably has a fastening device for the stationary fastening of the door drive in the region of the door shaft to be driven. The arrangement of a fastening device on the second base structure part allows better consideration of different installation situations by selecting the respective second basic structural part. In addition, when providing a damping unit in the connecting region between the two basic structural parts, improved damping against torque surges can then be achieved. The motor is arranged on the first base structure part. If, therefore, an attachment of the door drive to the second base structure part and an attenuation between the two basic structural parts are provided, the structure-borne sound originating from the engine is attenuated and not transmitted to the attachment. Thus, a quieter run can be achieved.

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

Fig. 18 is a plan view from above in Fig. 16 seen on the mounting interface. In Figs. 1 and 2, an automatically driven gate 10 with a door shaft 12 and designed as a Wellentorantrieb or direct drive door drive 14 is shown.

The gate 10 has a movable in a guide 16 between a closing end position and an opening end position door leaf 18. The door shaft 12 is formed as part of a weight balancing device 20 and has a force storage device, here in the form of a torsion spring 22, which balances the weight of the door leaf 18 as far as possible during its movement. For this purpose, the door shaft 12 is coupled in a gear to the door leaf 18 such that the door shaft 12 rotates when moving the door leaf 18. In the example shown, this geared coupling is realized by cable drums 24 and wire ropes 26 that can be wound thereon.

The door operator 14 is connected to one end of the door shaft 12 for rotatably driving the same.

FIGS. 1 and 2 further show walls 28 of a building 30, which has a door opening 32 which can be closed by the door 10. The door drive 14 is produced in industrial mass production and is so adaptable in its manufacture that it can be adapted to different gates 10 and different buildings 30 with corresponding installation situations.

The door drive 14 has, as shown in FIG. 2, a drive housing 34. The drive housing 34 has a plurality of hoods or covers 36, 37. In the actual drive housing 34, the drive elements are mounted on a support structure or base structure 40.

FIGS. 3 to 5 show the door drive 14 without the covers 36 and 37, so that the drive elements and the base structure 40 can be seen. The base structure 40 has a first base structure part 42 and a second base structure part 44, which are detachably connected together at a fastening interface 46.

The first base structure part 42 is formed as a base plate or base plate 48. On the base plate 48, a motor 50, an electrical unit 52, a decoupling device 54 and a decoupling sensor 56 and a position sensor 57 is attached.

The motor 50 is designed as a geared motor and has a motor housing 58, an electric motor 60 and a self-locking worm gear 62. Accordingly, the output shaft of the motor 50, hereinafter referred to as the motor shaft 64, is connected to the output shaft (not shown) of the worm gear 62. This motor shaft 64 has a first gear in the form of a first sprocket 66.

The electrical unit 52 has a power unit 68 with transformer and power electronics and a controller 70 which controls the electric motor 70 via the power unit 68. In another embodiment, not shown here, the electrical unit 52 has only the power unit 68. The controller 70 is in a separate control housing (not shown), which is fixedly secured in the region of the door drive 14, housed.

By means of the decoupling device 54, the motor shaft 64 can be decoupled from the worm gear 62, so that the first sprocket 66 can rotate freely in the decoupled state. For this purpose, the decoupling device 54 has a manually actuated by not shown actuating elements coupling pin 72 which is controlled by a cam 74 axially movable upon rotation. This axial movement is transmitted to the motor shaft 64 via a coupling claw 76 acting as a lever element, so that it can be moved in the axial direction from its engagement with the worm gear 62. The uncoupling sensor 56 detects a movement of the clutch claw and thus a decoupling process. The position sensor 57 has a pinion 57a (FIGS. 4 and 5) whose axis is guided through an opening 57b (FIGS. 6 and 7) and which meshes with a drive chain 96 in a form-fitting manner. Even with decoupling the pinion 57a thus remains geared to the output shaft 80, so that its rotational angular position and thus the position of the connected door leaf 18 can always be determined. The position sensor 57 is designed as an absolute value encoder, which supplies the absolute rotational angular position to the controller 70.

In an embodiment, not shown here, in which the position sensor is arranged on the motor, the controller 70 is designed such that upon receipt of a signal of Entkuppelsensors 56, which indicates a again after a disengaging clutch condition again, a reference run for the gate 10 performs, in which the position, in particular the end positions of the door leaf 18 are taught. In the illustrated embodiment, with the position sensor 57 provided in the drive train from the engine to the output shaft behind the disconnecting device 54, the position transmitter 57 always indicates the absolute position of the door leaf after a first teaching after commissioning, so that a reference travel after uncoupling and in principle also the uncoupling sensor can be dispensed with is.

The second base structure part 44 is likewise designed as a plate, which can be connected to the base plate 48 via the attachment interface 46. The second base structure part 44 has an output shaft 80 of the Torantriebes14, which is rotatably mounted on a bearing arranged at a certain radial distance from the motor shaft 64 bearing 82. The output shaft 80 has on one side a shaft coupling 84 with a connection part 86, which can be placed on the end of the door shaft 12. A radially inwardly pointing projection 88 engages when placed on an existing on the door shaft 12 longitudinal groove 90 (FIG. 2), so that the connecting part 86 rotatably seated on the door shaft 12. At the other end, the output shaft 80, a second gear, here in the form of a second sprocket 92, on. The two gear wheels on the motor shaft 64 and the output shaft 80 are connected via a drive gear 94 with each other geared. The traction mechanism 94 has a drive chain 96 in the embodiment shown here.

6 and 7, the first base structure part 42 with the drive elements - in particular motor 50, electrical unit 52 - alone. For fixing the second base structure part 44, the first base structure part 42 has two openings 98, 99, the attachment interface 46 on the second base structure part 44 has openings 100, 101 provided with a corresponding spacing from the openings 98, 99. Screw fasteners 102 extend through these openings 98 to 101 in order to fasten the two base structure parts 42, 44 together.

Both the first and the second base structure part 42, 44 is provided with an angled, for example, bent edge region 104, 105. At the attachment interface 46, the two base structure parts 42, 44 engage with their angled edge regions 104, 105 telescopically. The openings on one of the two base structure parts 44, 42 are designed as elongated holes. In the example shown here, the openings 100, 101 on the second base structure part are designed as such elongated holes 106, 108. The elongated holes 106, 108 have a width which is smaller than the diameter of the circular openings on the other base structure part.

A door drive system for producing such a door drive 14 has a first base structure part 42, which can always be produced in industrial mass production, which, as shown in FIGS. 6 and 7, already has all the corresponding drive elements - here, for example: motor 50, electric unit 52, Uncoupling device 54, uncoupling sensor 56, motor shaft 64 with first sprocket 66 - is provided and is preferably fully assembled. The door drive system further comprises an assortment of different second base structure parts. The second base structure part 44 is thus as replaceable output module formed. 8 and 9 show a first output module 110 with a first output shaft 111. FIGS. 10 and 11 show a second output module 112 with a second output shaft 113. FIGS. 12 and 13 show a third output module 114 with a third output shaft 115 And FIGS. 14 and 15 show a fourth output module 116 with a fourth output shaft 117.

The output modules 110, 112, 114 and 116 differ by their output shafts 110, 113, 115, 117 and the distance of the bearing 82 of the mounting interface 46. The mounting interface 46 is formed in all output modules 110, 112, 114, 116 the same. The output shafts 111, 113, 114, 116 each have second gears - here the second chain sprockets 92 - each with different diameters. The plate-shaped area around the bearing 82 is in each case formed in such a way that it protrudes radially over the respectively second chain sprocket 92 inserted over its entire circumference. The second to fourth output modules 112, 114 and 116 have output shafts 113, 115, 117 with connecting parts 86, which are each formed the same. However, the output shaft 111 of the first drive module 110 is different in terms of its shaft coupling 84: This first output shaft 111 is designed as a hollow shaft, which is placed with the projection 88 on a door shaft 12 with a correspondingly smaller diameter.

The door drive 14 is thus modular in design, with a selectively replaceable output module 110, 112, 114, 116. Depending on the installation situation on the door 10 and / or type of the door shaft 12, the respectively suitable output module 110, 112, 114, 116 selected and attached to the always substantially the same trained and mounted base plate 48. The attachment takes place by means of Schraubbefestiger 102, which are shown in detail in FIGS. 16 to 18 in section. These Schraubbefestiger 102 each have a screw 120 with a screw head 122 whose diameter is greater than the diameter of the openings 98, 99. Subsequent to the screw head 122, the screw 120 has a step portion 124 whose diameter is a lot smaller than the diameter the openings 98, 99, so that he can be used with play in these openings 98, 99. Subsequent to the step region 124, the screw 120 has a screw shank 126, which is designed to pass through the elongated holes 106, 108, so that the boundary of the oblong holes 106, 108 rests on the step region 124.

The Schraubbefestiger 102 further includes a nut 128 for screwing onto the screw shaft 126 and an elastomeric element which is inserted between the screw head and the step portion on the one hand and the openings 98, 99. As can be seen in particular from FIG. 17, the boundary of the openings 100, 101 is clamped between the nut 128 and the step area 124. As a result, the general position of the base structure parts 42, 44 is fixed to one another. Thus, the tension of the drive chain 96 is maintained. A displacement of the screw 120 in the slot 106, 108 is no longer possible with tightened nut 128.

The elastomer element is designed for example as a rubber ring 130. Due to this rubber ring 130, the first base structure part 42 and the second base structure part 44 are not rigidly connected to each other, but these are to a certain extent elastically movable to cushion shocks or the like and in particular within the elasticity of the rubber ring 130 also still slidably. The rubber ring 130 forms an elastic buffer. For this purpose, the respective angled edge portions 104, 105 are arranged with play to each other, so that even a certain rotation of the base structure parts 42, 44 is allowed to each other so as to buffer torque shocks.

In the manufacture of the door drive is thus from the first base structure part shown in Fig. 6 or 7 and a respectively suitably selected second base structure part 44, the one of the output modules 110, 1 12, 114, 116 according to the specifications, for example, the specifications of the gate 10th is selected, a base structure 40 formed, as shown for example in Figs. 3 to 5 and 16 to 18, constructed. Then will be the covers 36, 37 are applied to protectively cover the two sides of the base structure 40.

By selecting different output modules 110, 112, 114, 118, it is possible in particular to set the suitable position of an advantageous door drive attachment 15 to the door shaft 12, as indicated in FIG. 2. This door drive attachment 15 acts directly on the second base structure part 44 in a square opening 134 (FIGS. 3 to 14) forming a fastening device 132.
