The special feature of this device is that every rope a slack rope safety device is assigned, which prevents changed that when a rope is relieved of the already ge formed rope wrap jumps up and when opened again wrap winding layers ascending on top of each other. This Slack rope protection prevents on the one hand due to the jerk-free pull-up process the emergence of additional Vibration processes, but no measures have been taken fen, the naturally occurring vibrations, which at  for example through the direct coupling of the drive unit be generated or amplified on the winding shaft peln. So the conventional noise emissions remain consist.

DE-AS 27 22 143 is a pull-up separator slope for theater stages, sports halls or the like knows, the curtain two at regular heights the curtain webs connected by cross-sections, their un tere ends over tension belts or the like with one with egg Connected to an electric motor-driven winding shaft are, and two interception devices to secure the separation curtain against a fall. The Winding shaft consists of shaft sections, each because connecting elements compensate by bending moments are coupled together. For power transmission is a gearbox connected to the motor via a connection link, such as a V-belt, a chain or the like, with egg nem shaft section of the take-up shaft connected. This one generated vibrations of the engine or the transmission thus both directly via the connecting link to the up transfer winding shaft, as well as on the ceiling structure tion on which the motor and the rotary bearings for the wel len sections are firmly connected. In addition to that on the interception devices, here for example by a Tracer roller moving along a ratchet wheel, additionally generates vibrations. This leads to high noise schemes. A corresponding curtain device with corresponding disadvantages are known from DE 28 41 454.

DE 31 27 095 also shows a separable partition curtain for theater stages, sports halls or the like, in DE-AS 27 22 143 shown type, here the on winding shafts consists of several shaft sections, which via universal joint or rubber-elastic shaft couplings are coupled together and the two outer ones at least one shaft section having a winding shaft  te are each provided with an interception device. At mainly for securing the load on waves break designed device, however, turns out to be partly out that the engine or transmission and the interception devices (feeler roller, ratchet wheel) produced Schwin practically unhindered in the entire elevator direction for the curtain. This leads like too high noise emissions.

EP 0 671 195 shows a motorized device to adjust on a horizontal support rod ing stage sets or the like, the Vorrich a three-dimensional self-supporting horizontal Carrier that unites over its entire usable length central space, limited to a geared motor unit one end of the carrier is arranged and their output shaft is coupled to a transmission shaft, which is extends horizontally in the central room, and a number of suspension means for hanging the support bar with the possibility of height adjustment of the same, each the suspension means koa on the transmission shaft xial to this and rotatably connected to this chain drive pulley and one over the chain drive chain running chain section, the Ket regardless of the height of the support rod vertical run, at the free end of the support bar hangs, and has a loose run that belongs in an associated Containers is included. To hang the Transmission shaft housing parts are provided, which over elastic sleeves are connected to the carrier, whereby a slight swinging back and forth of the housing parts and thus flexible suspension is guaranteed. Regarding Ge However, noise emissions have the following disadvantages on. On the one hand, there are generated by the geared motor unit Vibrations through the direct connection of the output shaft cannot be uncoupled from the transmission shaft. On the other hand additional noise emissions arise from the use  a chain for pulling up the support bar both when a chain section interlocks with the ket ten drive disc, as well as when picking up the loose Trumms in the container.

Presentation of the invention

It is therefore an object of the present invention to To provide a device for lifting a load in the a flexible one with minimal equipment expenditure and low-noise use is made possible.

This task is carried out with regard to the device Hoisting a load by the features of claim 1 and regarding the group of pull-up devices hen a load solved by the features of claim 23.

The device for lifting a load comprises an on drive device having an output shaft, a Hanging device for hanging a load bar with the Possibility of height adjustment of the same, the Auf Hanging device has a drive component, via the egg ne connected to the load rod towing device is a transmission shaft through which the drive construction part of the suspension device is coupled with the output shaft pelt is, the drive device and the suspensions device connected to a fastening device are. The drive device, the output shaft, the Transmission wave, the suspension device and the befe Stigungseinrichtung form a vibration over this support circuit in which a vibration decoupling device device is integrated. This facility prevents the off propagation of vibrations in the vibration transmission circuit, wherein individual elements of the vibration decoupling device  device at various points in the circuit can (invention).

It proves to be advantageous to use an element of Vibration decoupling device between the output shaft and the transmission shaft to be arranged because of vibrations generated directly by the drive device be decoupled at the point of occurrence. To match one the advantage is achieved when an element of vibration decoupling device between the drive device and the fastening device is integrated. Furthermore, an element of the vibration decoupling device between the fastening device and the suspension device be ordered. For decoupling the vibrations within the transmission wave, which have several sections , it is further advantageous to the individual sections by elements of the vibration decoupling device from to separate each other. There is a combination as required several elements of the vibration decoupling device the different places in the vibration transmission circuit possible. (Possible locations for the vibration decoupling device).

According to an advantageous embodiment, the An drive component on a drum on which the traction device is wound up. The pulling device can be a belt, such as a steel band, which on the one hand is hot experienced and inexpensive. A tear-proof re and vibration-damping traction device represents a meh rere strands having flat rope. Here are meh Several strands are laid next to each other and with elastic mate rial connected, whereby here by dividing the train force on several strands if a strand breaks sudden tearing of the entire band is prevented. There by that the band-like traction devices radially match other, but increases with increasing wick degree of winding radius, which is a changing high  pulling speed of the load rod results. To the half a constant speed of the load bar ensure, it is advantageous to the current winding radius us of the drum, for example by means of an absolute value bers on the drive device or by means of a button on the drum. (Draw gear as Ribbon / flat rope).

The traction device can also have a round rope, that is wound axially on the drum. However, since with a corresponding thread pitch of the drum, the rope gear and thus the entire load bar or one of it Annual prospectus postpones what, for example, at Thea events give a bad visual impression averages, it is advantageous to take measures to avoid a to take such displacement of the load bar. To the there is the possibility of the drum or several Drum axially for example by a screw drive to move that the rope outlet in the same place remains. It is also possible to use a spooler for con trolled rewind, which also uses Rope is axially wound on the drum and the rope outlet remains in the same place. By means of such Measures will be a controlled and smooth winding of the rope reached, causing no additional vibrations or noise. (Pulling device as a rope with Axial compensation).

According to an advantageous embodiment, the bobbin apparatus at least one pulley on which he Most vibrator is stored, which in turn in one Fixed bearing and a floating bearing is stored. According to a white teren advantageous embodiment is the winder but developed so much that on the one hand he is a verbes sert winding and also an acquisition of the load condition of the rope to be wound. There at the bobbin has two pulleys, the  first deflection roller in the first vibrator and the second Deflection roller in a second oscillator, whose swivel axis with the axis of rotation of the first deflection roller falls, is stored. To record the rope load condition the first transducer has a stop against which the second transducer with the second deflection roller End section depending on the abut on the rope the load is pressed. This configuration of the Spulappa rats has the advantages that the controlled on wind the rope large lengths of rope on the drum can be wound or saved. Furthermore is the equipment expenditure reduced to a minimum, d. H. there are no additional parts, such as additional scanning devices or waves for detection of the rope load condition, which means a clearly ge lower noise level occurs. Furthermore, the use of egg Slack rope safety device unnecessary, because with relieved State or a state of lower load the operation of the Motor by means of an end scarf connected to the stop ters is interrupted (winder).

According to a further advantageous embodiment of the Invention has the vibration decoupling device elastic coupling. It is important to do so make sure that the material from which the elastic coupling exists, or its elastic properties accordingly the expected vibration frequencies are designed in such a way that on the one hand no resonance effects occur, on the other hand however the vibration amplitudes due to the elastic coupling be reduced to a minimum. Instead of or in addition to the elastic coupling, a swinging bearing ver If appropriate, the corresponding points of view must be taken into account term. (Design of the vibration decoupling device tung).

Brochure pulling device

Fig. 1 shows a schematic representation of the device for pulling up a load, here especially a brochure pulling device, according to a first exemplary embodiment of the present invention. Here, Fig 1a 1b shows. Prospektzugvorrichtung and a front view of Fig. A side view taken in Fig. 1a Darge set line bb.

Here, a drive means 1 in the form of a motor-gear-brake unit 1 is processing at the Befestigungseinrich 20, the set place in the simplest case from the ceiling 1 of A is formed, mounted, being vertically movable (in a self-aligning bearing) 2 and elastic at 3 is. The oscillating bearing 2 is formed, for example, by a bearing in which the drive axis is given a degree of oscillation; the elastic mounting 3 is, for example, by an elastic bracket 3 he reaches. The torque is supported by a suitable device (not shown), the support being provided with a device for measuring the torque and thus the load. The output shaft 22 of the drive device 1 is connected via a vibration decoupling device in the form of an elastic coupling 4 to the transmission shaft 5 . Furthermore, the drive device 1 and the output shaft and part of the transmission shaft are surrounded by a housing 25 , which consists of a sound-absorbing material, such as porous or fibrous absorption materials. Such measures achieve optimal vibration decoupling both of the mechanical components, such as the output shaft and the fastening of the drive unit, and of the airborne sound.

Via the output shaft 22 and the transmission shafts sections 5, which are arranged coaxially in the first embodiment to each other and horizontal, on which are driving components 6 in the form of belt drums 6 is driven. For further vibration decoupling, the individual transmission shaft sections 5 are connected to one another via mechanical couplings 4 . The drums 6 are attached by means of corresponding holding parts 21 to the fastening device 20 , wherein they are mounted in an oscillating manner 9 in order to compensate for axial tolerances and to be able to absorb vibrations. Finally, tapes 7 are wound onto the tape drums 6 , whereby the height of a load rod 8 attached to the tapes 7 is adjusted.

As already mentioned above, the band-like tension devices 7 are wound radially one above the other, as a result of which the winding radius increases with an increasing degree of winding, which results in a changing pull-up speed of the load rod. Therefore, in order to ensure a constant speed of the load bar, it is advantageous to detect the current winding radius of the drum, for example by means of an absolute encoder (not shown) on the drive device or by means of a button on the drum (not shown).

In Fig. 1, the drums 6 are arranged so that the drum rotation axis is parallel to the axis of the load rod 8 or transmission shaft 5 . However, it is also possible to rotate the drums 6 through an angle, for example 90 °, in such a way that the drum axis is transverse to the load rod 8 . Each drum 6 is then driven, for example, by means of a bevel gear or a worm gear.

A steel belt 7 or a flat cable 7 can be used, for example, as the band-like pulling device 7 for pulling up the load rod 8 . In this case, Fig 2a shows a section 2b. Of the steel strip, and Fig. Is a cross section along the line bb shown in Fig 2a.. The ent long the width made of one part steel strip is inexpensive on the one hand, but it has the disadvantage that it breaks at the slightest crack K as a result of the notch effect. This is remedied by a flat rope consisting of several strands 7 i, which is shown in FIG. 3. Here, Fig 3a shows 3b provided. A portion of the flat rope and Fig. Is a cross section along the in Fig. 3a represents line bb. During manufacture, the individual strands 7 i are placed next to one another and connected with elastic material. If a strand 7 i now breaks, the sudden tearing is prevented by dividing the tensile load over several strands 7 i.

Bobbin

Instead of the belt-like pulling means, a round rope 14 can be used (see Fig. 4), being used here for winding rope drums 6 having a larger width than the band drums 6. To adjust the height of the load rod 8 , the round cable 14 is wound axially on the cable drums 6 , the cable outlet and thus the entire load rod 8 including a brochure attached to it (not shown) being shifted in accordance with the thread pitch. A measure to prevent the displacement of the cable outlet is to move each drum 6 axially, for example, by a Ge screw drive (not shown) so that the cable outlet remains in the same place. Another alternative measure is to assign a separate winding device 30 to each drum 6 .

The Fig. 4 show schematic views of a Trom mel 6 with a used in the present invention winding apparatus 30 for the controlled winding a round cable 14 in accordance with a first embodiment of Spulappa 30 rats. Here, FIG 4c illustrates. 4a is a front view of the Trom mel 6 with winding apparatus 30, Fig. 4b is a side view long the line ent shown in Fig. 4a bb, and Fig. Is a plan view taken along the line 4a shown in Fig cc..

The winder 30 consists of two arranged above a drum 6 deflection rollers 10 which are mounted in a vibrator 11 , the storage of the Schwin gers 11 in a fixed bearing 12 and a floating bearing 13 it follows. The pivot axis SA1 of the vibrator 11 , which runs through the two bearings 12 and 13 , corresponds to the axis of the cable piece 14 on which the load 8 is suspended. The axis of the vibrator SA1 shown vertically in FIG. 4 runs here perpendicular to the horizontal drum axis TA. The floating bearing 13 is held by the side parts 15 or supporting parts 15 , which also accommodate drum bearings 16 . In order to suppress noise emissions, the bearings 16 can be installed in the support parts 15 so as to be isolated from structure-borne noise (not shown). During the winding process of the rope piece 14 on the drum 6 , the vibrator 11 pivots about its axis SA1 in such a way that the rope 14 is axially wound in a controlled manner.

The winder shown in FIG. 4 can, however, be further developed in such a way that, on the one hand, it enables improved winding and, on the other hand, it also detects the load state of the rope to be wound up. Such an arrangement according to a second embodiment of the winding apparatus 30 is shown in FIG. 5.

In contrast to the example illustrated in Fig. 4 Reel apparatus 30 are in the process in Fig. 5, the winding apparatus shown two guide rollers 10 30 a, 10 b below the drum 6 is arranged. The first deflecting roller 10 a is in this case mounted in the first vibrator 11 , the storage of the first vibrator 11 again taking place in a fixed bearing 12 and a bearing 13 . The second deflection roller 10 b, however, is mounted in a second oscillator 17 , the pivot axis SA2 of which coincides with the axis of rotation 19 of the first deflection roller 10 a. The leadership of the rope 14 then runs, starting from the section connected to the load rod 8 , above the first deflection roller 10 a, below the second deflection roller 10 b and finally approximately vertically upwards to the drum 6 , on which the rope is wound in a controlled manner .

The principle implemented in this embodiment for detecting the load state of the rope 14 works as follows. Due to the load 8 on the rope 14 , the second vibrator 17 is pressed against the stop 18 due to the rope guidance described above. As soon as the load 8 falls below a certain level, which occurs, for example, during the unwinding of the rope 14 when the load 8 is placed on the floor, the second oscillator 17 will lift its weight from the stop 18 and a limit switch (not shown) will respond . Due to the detection device constructed in this way, the duration of the noise emission by the drive device 1 (see FIG. 1) is reduced to a minimum and no additional scanning shafts or springs are required for the second oscillator 17 , which results in less effort and due to the reduction in the number of interacting parts, this in turn leads to lower noise emissions.

In addition to the just described "slack rope notifying means", in which a limit load at too low rope responsive 8, it is also possible to form an "overload protection", so that the load is too great rope 8 or in case of failure during pull-up of the rope 14 , in which the load rod 8 hooks, for example, with other theater backdrops, the second deflection roller 10 b presses excessively against the stop 18 , whereby a second limit switch (not shown) interrupts the operation of the drive device.

Group of prospect train devices

Because of their simple and space-saving construction, the prospectus pulling devices described above are also suitable for collective use, in which several devices are arranged side by side. Fig. 6 is a schematic side view showing an arrangement of a Grup pe of apparatus for pulling up a load, in particular Prospektzugvorrichtungen, along the drum axis, according to a second exemplary embodiment of the invention. With the help of this arrangement, it is possible to maintain the load bar spacing of 200 mm that must be observed in many theaters. An upper drum 6 a and a lower drum 6 b are arranged one above the other in a bearing block (not shown). From the drums 6 a, the rope 123 a, 124 a runs over deflection rollers 120 and 121 to a load bar 8 a. The deflecting rollers 120 , 121 are mounted in oscillators (not shown), the axes 122 of which are approximately parallel to the rope pieces 123 a, which extend between the drums 6 a and the deflecting rollers 120 , and the tangents leading to the load bars 8 a Cut rope pieces 124 a. From the lower cable drums 6 b, the cable 123 b, 124 b runs accordingly over deflection rollers 125 and 126 stored in a vibrator (not shown) to the load rods 8 b. For reasons of noise, the deflection rollers 120 and 121 or 125 and 126 are not arranged in one plane, but in such a way that the rope 123 a or 123 b each transverse to the radial axes UA1 and UA2 of the deflection rollers, which are perpendicular to the axes of rotation the rollers stand, runs in (see Fig. 7). In other words, the rope 123 a or 123 b should run in at an angle to the corresponding roller levels.

Fig. 7 shows a front view of the arrangement shown in Fig. 6 Darge a group of devices for lifting a load, the drums with Spulap are specifically designed in detail. The upper drum 6 a is supported in bearings 127 and 128 and driven via elastic couplings 129 . The torque is passed through the flexible coupling 130 to the next upper drum (on which the same load rod is attached). To minimize noise emissions, the bearings 127 and 128 are installed in the support parts 131 and 132 structure-borne noise (not shown). To reduce the cost of directional engineering and the space required, the lower drum 6 b is installed together with the drum 6 a in a frame.

A device for pulling up a device is disclosed Load, in particular brochure pulling device, with an drive device, a hanging device for hanging a load bar with the possibility of height adjustment the same, a transmission wave, for coupling the An drive component of the suspension device with the drive shaft le, the drive device and the suspension device device are connected to a fastening device. For The device is there to minimize noise emissions formed in such a way that the drive device, the Output shaft, the transmission shaft, the suspension device device and the fastening device a vibration over Form support circuit in which a vibration decoupling facility is integrated. By means of this vibration device Coupling device is a propagation of vibration processes that lead to noise emissions, for example in the case of an elastic coupling by minimizing the Vibration amplitude reached. Such a device  is therefore particularly suitable for use, for example in event halls for theater or concerts, where loads transported with little noise or high have to be pulled.
