Description

The invention relates to an assembly method for a roll-up door, which has a winding shaft, a roll-up roller blind which can be wound on the winding shaft, a rotary bearing for rotatably supporting the winding shaft, a roller shutter drive motor for driving the winding shaft during operation of the roller shutter and a weight compensation device. Furthermore, the invention relates to a Rolltorantriebsvorrichtung for such a roller door. Finally, the invention relates to a use of a mounting aid in such a mounting method.

As rolling doors building closures are referred to, the wing is similar to a roller shutter wound on a winding shaft. The roller doors usually have a roller blind curtain, which is suitable for winding on the winding shaft. This can be, for example, a material web made of a flexible material or a so-called roller door, which is formed from a plurality of hingedly articulated lamellae. As a rule, guides for guiding the roller shutter curtain are provided laterally of the door opening to be closed by the roller shutter. Most above the door opening to be closed a rotary bearing for the winding shaft is provided. The vast majority of roller doors further include a roller shutter drive device with a roller shutter drive motor. The Rolltorantriebsmotor is usually an electric motor, often designed as a geared motor with self-locking worm gear, the output shaft is connected by gearing to the winding shaft. Due to the motor drive of the winding shaft, the roller door curtain can thus be wound onto the winding shaft or unwound therefrom.

To mount the roll-up door, the pivot bearing and the guides are usually first fastened in the region of the opening to be closed. The roller blind curtain must then be threaded into the guides.

At one of the EP 0 238 944 Known earlier assembly method for a roller door is a mounting aid on consoles that provide the pivot bearing for the winding shaft, this has been attached. The winding shaft has then been pulled together with the roll-up door curtain wound thereon by means of the assembly aid and Hebezugmitteln upwards. For this purpose, the assembly aid device provides a guide for the hoisting means so that the roller blind curtain is raised at a distance from the wall to which the brackets are fastened, and then pulled up to the wall above the brackets until the winding shaft reaches the assembly position. There, the pivot bearing for the winding shaft are attached to the console. Subsequently, a closing edge of the roller blind curtain is threaded into the guides and the roller blind curtain is introduced by unwinding into the guides inside.

Comparable mounting methods and mounting aids are from the DE 101 27 015 A1 as well as the DE 203 15 243 U1 known.

In the DE 10 2006 046 008 B3 On the other hand, an improved assembly method and an improved assembly aid for a roller shutter door are proposed, which is much simpler both from the expenditure on equipment and from the work involved. In this known assembly method, first the winding shaft without roller door curtain is rotatably mounted in its final pivot bearing in the area above the door opening to be closed. As an assembly aid then Montagezugmittel, the first ends are attached to the winding shaft and the second ends are attached to one end of the roller table curtain, which is stored as bales below the winding shaft. The winding shaft is then driven in rotation, so that the Montagezugmittel are wound on the winding shaft and the roll-up door curtain is pulled upwards. By further rotation of the winding shaft of the roller table curtain is then also wound on the winding shaft until the lower end of the roller table curtain is above the guides and can then be threaded into the guides. As a drive means for the winding shaft of serving later for the operation of the rolling shutter Rolltorantriebsmotor is proposed. A roller shutter with roller shutter drive motor and a counterweight device is from the EP 1 965 018 A2 known.

The object of the invention is to provide a mounting method for such a driven and provided with counterbalance roller door, so that the mounting method is relatively simple and simple auxiliary devices feasible and the roller door mounted therewith is relatively inexpensive and environmentally friendly operable. In addition, a device for carrying out the method should be specified.

This object is achieved by a mounting method and a roller shutter drive device and a use with the features of the independent claims.

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

• a) Montage der Wickelwelle ohne Rolltorbehang mittels der Drehlagerung am Einsatzort,
• c) Antreiben der Wickelwelle mit einer ersten Übersetzung mittels des Rolltorantriebsmotors, um den Rolltorbehang durch Drehung der Wickelwelle auf die Wickelwelle aufzuziehen,
• d) Anschließen der Gewichtsausgleichseinrichtung an die Wickelwelle und
• e) Ändern der Übersetzung zwischen Rolltorantriebsmotor und Wickelwelle für den Betrieb zu einer zweiten Übersetzung, die kleiner als die erste Übersetzung ist.

The invention provides a mounting method for a roll-up door, which has a winding shaft, a roll-up roller blind which can be wound on the winding shaft, a rotary bearing for rotatably supporting the winding shaft, a roller shutter drive motor for driving the winding shaft during operation of the roll-up door and a weight compensation device, characterized by the steps:

• a) assembly of the winding shaft without roller shutter curtain by means of the pivot bearing at the site,
• c) driving the winding shaft with a first translation by means of the Rolltorantriebsmotors to raise the Rolltorbehang by rotation of the winding shaft on the winding shaft,
• d) connecting the weight compensation device to the winding shaft and
• e) Changing the ratio between Rolltorantriebsmotor and winding shaft for operation to a second translation that is smaller than the first translation.

The order of steps d) and e) can be chosen arbitrarily.

In particular, the ratio between the input speed and the output speed of the transmission or the gear stage, i = n ₁ : n ₂ (n ₁ rotational speed of the driving shaft, n ₂ rotational speed of the driven shaft) is referred to as translation. For example, if i <1, a translation is fast; if i> 1, a translation is slow. For example, in gear and chain transmission, a translation would be possible over the number z of teeth of the gears, eg i = z _output / z _drive .

The assembly method is particularly suitable for a roller door, as in the EP 1 965 018 A2 described and shown. It is for more details on the interpretation of the counterbalancing device and the roller door expressly to this document EP 1 965 018 A2 directed. In particular, the invention is suitable for roller doors with Rolltorpanzern as Rolltorbehang. With the method according to the invention, it is also possible to lift and mount heavy roller shutters with simple mounting means.

By means of a weight compensation alignment, a great ease of movement for the winding shaft can be achieved over the course of the door path during winding and unwinding. Due to this, the roller shutter drive can be made relatively weak; The roller shutter door can also be effectively driven by a very small roller door drive motor. However, such a roller door drive would not be suitable for pulling up a Rolltorpanzers during assembly, insofar as special equipment for installation and a complicated assembly process would be necessary.

Also in the case of the DE 10 2006 046 008 B3 known mounting method of Rolltorbehang is raised by means of Rolltorantriebsmotors on the already without roller shutter curtain previously mounted winding shaft. In the known method, however, this mounting requires relatively large forces, for which the roller door drive motor must be designed according to the known method; Therefore, to carry out this known method relatively large-sized Rolltorantriebsmotoren necessary.

According to the invention, however, it is now provided to drive the winding shaft with a different translation than during operation for assembly. During assembly, the winding shaft by means of Rolltorantriebsmotors, which is later responsible for operation, driven, but with a translation that is much larger than the later translation in actual operation. In this way, the mounting of the roller table curtain takes place at low speed and much higher power. As a result, the roller door drive motor can be dimensioned correspondingly small and driven with correspondingly little energy. For the increased forces during assembly serves the larger translation, which is necessary only for mounting. For the actual operation then the translation is changed. In this operation, then the weight compensation device, so that a total of the rotation of the winding shaft much lower forces than during assembly are necessary. With the method according to the invention, therefore, a very simple small roller door drive motor can be used for the assembly, without the comfort would be reduced in normal operation by very slow operation. Therefore, the roller shutter can be effectively driven in later operation with the larger-sized electric motor.

Since the larger translation is needed only during assembly, it is provided in a particularly advantageous embodiment of the assembly process to interpose a mounting intermediate gear to provide the first translation between the winding shaft and the Rolltorantriebsmotor. The driving of the winding shaft in step c) then takes place by means of the roller shutter drive motor, which transmits its power via the mounting intermediate gear with the larger first gear ratio to the winding shaft. After the roller shutter drive motor has done its job during assembly, the intermediate assembly gear can then be removed. As a result, a relatively simple gear between the roller shutter drive motor and the winding shaft can be provided for the operation for delivering the second translation, for example, a simple chain transmission with only two sprockets and a chain as Endloszugmittel.

The intermediate mounting gear is only used temporarily during the assembly phase and can then be dismantled. It can then by the fitter be taken and re-used for later assembly operations on other roller doors. In this respect, such a mounting intermediate gear represents a particularly advantageous embodiment of a mounting auxiliary device, which - like the auxiliary assembly devices of the prior art according to the EP 0 238 944 A1 and the DE 101 27 015 A1 - Temporarily used for mounting the roller shutter. However, such an assembly aid according to the invention is significantly simpler and less expensive than the previously used for the installation of rolling doors auxiliary equipment according to the prior art.

the unit off Fig. 1 in the presentation of Fig. 1 , but without the assembly aid in the setting for the operation of the roll-up door.

In the Fig. 1 and 2 Parts of a roll-up door 10 to be mounted are shown in the course of assembly together with an auxiliary assembly device 12.

The roller door 10 has a winding shaft 14, a pivot bearing 16 for the winding shaft 14 and a roller shutter drive device 18 for driving the winding shaft 14 during operation of the roller shutter 10th

On the winding shaft 14 is in operation of the roller shutter 10 a purely in Fig. 8 shown roller door curtain 152 for opening and closing the roll-up door 10 up and unwound. Like from the Fig. 1 and 2 it can be seen for this purpose the winding shaft 14 is mounted in the pivot bearing 16 on brackets 20, which are to be fastened laterally in the region of the door opening to be closed. In the Fig. 1 and 2 For this purpose, only one of the roller door drive device 18 exhibiting upper side region of the roller shutter 10 is shown.

At the consoles 20, the pivot bearing 16 is attached to an upper boom 22. Below the winding shaft 14 is still a lateral guide 24 for the roller shutter curtain 152 attached to each of the brackets 20.

At the in the Fig. 1 and 2 shown bracket 20 is still further attached to a drive bracket 26 to which the Rolltorantriebsvorrichtung 18 is held.

The winding shaft 14 has a shaft 28, which is the winding area for the roller shutter curtain 152 and is provided with radially projecting ring elements 30, which serve as a support bearing for placing the bottom layer of the wound roller shutter curtain 152.

At the in the Fig. 1 and 2 shown, the roller shutter drive device 18 associated end of the winding shaft 14 is a winding shaft drive wheel 32 is keyed to the winding shaft 14. The winding shaft drive wheel 32 serves for the geared connection of the winding shaft 14 to the roller shutter drive device 18.

In the example shown here, the winding shaft drive wheel 32 has a chainring 34 for meshing with drive chains, which will be explained in more detail later.

The later assembled roller shutter 10 is provided with a counterbalancing device 36, from which in the Fig. 1 and 2 only parts, namely a spiral element 37, on which a traction means, such as a wire rope (not shown) according to the torque requirement with a variable distance to the winding shaft rotation axis 38 wound, and a deflection roller 39 which is mounted on the console 20, are shown. In operation, located within the trained as a hollow profile bracket 20, a force storage device, such as a coil spring package or within the console 20 movable up and down weight. The traction means is connected in operation with one end to the energy accumulator, then guided over the guide roller 39 to the spiral element and attached to the other end to the scroll member 37 so that it is up or unwound upon rotation of the winding shaft 14 thereon to create a counterweight for the wound on the winding shaft 14 Rolltorbehang 152. An embodiment and the function of such a weight compensation device are in the EP 1 965 018 A1 explained in more detail, to which reference is expressly made for further details.

The roller door drive device 18 has a module 40 of a modular door drive system.

Like from the Fig. 3 and 4 can be seen, the module 40 without the in the Fig. 1 and 2 shown covers, this module 42 has a base structure part 42 which can be fastened with fastening openings 99 and 98 by fastener 96 to the drive bracket 26.

Like from the Fig. 3 and 4 As can be seen, the base structure part 42 is formed as a base plate or base plate 48. On the base plate 48 is a roller shutter drive motor 50, an electrical unit 52, a disconnecting device 54 and a decoupling sensor 56 are attached.

The roller door drive motor 50 is designed as a geared motor and has a motor housing 58, a (DC) electric motor 60 and a self-locking worm gear 62. Such types of geared motors are e.g. also used as windscreen wiper motors in automotive engineering. This type of gear motors are thus mass-produced, which are available on the market very cheaply. The output shaft of this roller shutter drive motor 50, which is referred to below as the motor shaft 64, is accordingly the output shaft of the worm gear 62. This motor shaft 64 has a driven gear 44 in the form of a chainring 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, wherein the controller 70 is then housed in a separate control housing.

By means of the decoupling device 54, the motor shaft 64 can be decoupled from the worm gear 62, so that the output gear 44 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 axially movable during rotation, controlled by a cam 74. 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 pawl 76 and thus a de-coupling process.

Like from the Fig. 1 and 2 Referring again to FIG. 1, the auxiliary assembly device 12 includes an intermediate assembly gear 100 on, which is connected between the winding shaft 14 and the Rolltorantriebsmotor 50 to provide a greater translation for the assembly process.

The mounting intermediate gear 100 is described below with reference to the representations in the Fig. 5 to 7 explained in more detail.

The mounting intermediate gear 100 has a transmission input shaft 102 and a transmission output shaft 104 and a gear housing 106 as a holder for mounting the mounting intermediate gear 100 between roller shutter drive motor 50 and winding shaft 14. The transmission input shaft 102 is designed to be connected to the roller shutter drive motor 50 and, for this purpose, has a transmission input gear in the form of an input pinion 108. Further, a smaller gear 110 is keyed to the transmission input shaft 102 inside the transmission case 106.

The transmission output shaft 104 is designed for connection to the winding shaft 14 and has an output pinion 111 for this purpose. Further, a larger gear 112 is keyed on the transmission output shaft 104, which meshes with the smaller gear 110 of the transmission input shaft 102.

The gear housing 106 is simply formed in the illustrated embodiment by two retaining plates 114, 116, which are fastened with screws 118 with spacer sleeves 120 at a distance from each other. In the holding plates 116, 114 are also provided slots 122 for slidably securing the gear housing 106 on the drive bracket 26.

The input gear 108 constitutes a transmission input gear and is made larger in diameter than the output gear 111 constituting a transmission output gear.

Like from the Fig. 1 and 2 it can be seen, the output 44 of the roller shutter drive motor is connected by means of a first Anschlußendloszugmittels 124 in the form of a first smaller drive chain to the Getriebeantriebsrad the mounting intermediate gear 100 for assembly. The through the output pinion 111th formed smaller Getriebeabtriebsrad is connected by means of a second Anschlussendloszugmittels 126 in the form of a second, larger drive chain to the winding shaft drive wheel 32.

For operation after assembly will, as in Fig. 9 is shown, the intermediate assembly gear 100 removed; and the output gear 44 of the roller shutter drive motor 50 is connected by means of an endless traction means 128 used in operation, here in the form of a third, even longer drive chain, directly to the winding shaft drive wheel 32 without interposition of the intermediate assembly gear 100.

By interposing the intermediate assembly gear 100 thus a ratio between the winding shaft 14 and the Rolltorantriebsmotor 50 is increased for assembly and reduced again by removing and immediate connection.

The mounting intermediate gear 100 thus forms a ratio changing device 130 for the roller shutter drive device 18th

The method for assembling the roller shutter 10 will be described below with reference to Fig. 1 and 2 . 8th and 9 explained in more detail.

First, the brackets 20 in the area left and right of the door opening 140 to be closed, as in Fig. 8 shown, fastened, and the winding shaft 14 is mounted without Rolltorbehang with the pivot bearing 16 on the brackets 20. The roller door drive device 18 with the module 40 is attached to one of the brackets 20. The mounting auxiliary device 12 with the mounting intermediate gear 100 is also attached to the drive bracket 26, with which the module 40 is fixed to the console 20. The two Anschlussendloszugmittel 124, 126 are connected and clamped, so that in the Fig. 1 and 2 shown in detail unit 150 with Rolltorantriebsvorrichtung 18 including mounting intermediate gear 100 and Winding shaft 14, still without the other parts of the weight balancing device 36 is formed.

The following is on the Fig. 8 Referred to, where these in the Fig. 1 and 2 shown unit 150 is shown for simplicity only indicated as a box. Roll-up roller blind 152, which is rolled up without a winding shaft, is deposited below open wind-up shaft 14 with packaging and support elements 154 that are open at the top. The first ends 156 of two assembly traction means in the form of mounting straps 158 are secured to the winding shaft 14, and the second ends 160 of the mounting straps 158 are secured to fasteners 162 at the upper end 164 of the roller table hanger 52. By driving the winding shaft 14 so that the door opening 140 directed towards the side of the winding shaft 14 up and the side facing away from the door opening 140 side of the winding shaft 14 rotates down, the mounting straps 158 wound on the winding shaft 14 and so is the roller shutter curtain 152 pulled up. Even if the upper end 164 reaches the winding shaft 14, the winding shaft 14 is slowly but powerfully driven by the Rolltorantriebsmotors 50 and the intermediate intermediate mounting gear 100 with the small ratio until the entire roller shutter curtain 152 is wound on the winding shaft 14 and the lower end 166 of the roller table curtain 152 comes to rest above the upper end of the lateral guides 24. Then, the direction of rotation of the winding shaft 14 is reversed and the lower end 166 of the roller table curtain 152 is threaded left and right in the lateral guides 24. Subsequently, the winding shaft 14 is rotated further, so that the roller shutter curtain 152 completely unwinds into the guides 24 and thus into its closed position from the winding shaft 14. Thereafter, the mounting straps 158 are removed, and the upper end 164 of the roll-up door curtain 152 is connected and secured to the winding shaft 14.

Subsequently, the wire rope of the counterbalancing device, not shown here, is connected to the force accumulator (also not illustrated) of the weight compensating device 36, guided over the deflecting roller 39 and connected to the spiral element 37 such that it correspondingly wound on the spiral element 37. This is done with appropriate position of the winding shaft 14 such that the energy storage is initially relaxed and then tensioned by rotation of the winding shaft 14 accordingly.

All rotations of the winding shaft 14 in the course of assembly are performed with the interposition of the intermediate assembly gear 100 with the large translation at low speed, but greater force than during operation of the roller shutter 10. The installer can react more quickly due to the lower speed and shut down the roller door drive motor 50, if any step of the assembly does not work in the desired manner and can intervene correspondingly quickly manually corrective. Further, due to the larger gear ratio, the process of pulling up a relatively heavy roller shutter with a standard geared motor from the automotive electrical system can be easily performed.

After creation of the weight compensation by the weight balancing device 36, the roller shutter 10 is very smooth. Therefore, after assembly of the weight balancer 36, the intermediate assembly gear 100 as well as the two terminal drums 124 can be removed; and the roller door drive motor 50 can be connected by means of the intended for operation Endloszugmittels 128 to the winding shaft with the smaller translation, as in Fig. 9 is shown.

In the embodiment shown, a translation i = Z _output / Z _drive = 6: 1 is selected in the normal door operation without mounting intermediate gear 100. There are 10 teeth on the motor chainring 66 (Z _drive = 10) and 60 teeth on the winding shaft chainring 34 (Z _output = 60) available.

Due to the mounting intermediate gear 100 several translation stages are switched in between. The first stage provides in the embodiment shown here a translation i1 = 1.6: 1. There are 10 teeth on the motor chainring 66 and 16 teeth on the input pinion 108 here. The second stage provides a translation i2 = 2.6: 1; because there are 25 teeth on the smaller gear 110 of the transmission input shaft 102 and 65 teeth on the larger gear 112 of the transmission output shaft 104 in the illustrated embodiment. The third stage provides a translation i3 = 5: 1; because there are 12 teeth on the output pinion 111 and 60 teeth on the winding shaft chainring 34 available. As a total ratio, the intermediate gear assembly thus provides a translation iM = (1.6 x 2.6 x 5): 1 = 20.8: 1 (ie, a slow gear ratio). During assembly, a first ratio of, for example, iM = 20.8: 1, is thus used, and in operation, a second translation of z. B. 1 = 6: 1, used, wherein the second translation is smaller than the first translation.

Depending on the weight of the roller shutter curtain 152 but other translations than those mentioned above can be considered. For this purpose, the intermediate assembly gear 100 (not shown) by another intermediate mounting gear, which provides a different translation, to be replaced.

Preferably, the translation for assembly is increased from that for normal operation by a factor that is between about 2 and 4.
