Definitions

  • the invention relates to a device for winding a nonwoven fabric for the thermal and acoustic insulation of buildings, in particular made of mineral fibers, preferably rockwool, with a bulk density of up to 85 kg / m 3 , with a conveyor device which promotes the nonwoven fabric in the region of a winding station, in particular a conveyor belt, the winding station having a deflection device which receives an end of the nonwoven fabric entering the winding station and deflects it at an angle> 100 ° in the direction of the incoming nonwoven fabric.
  • Nonwovens for the thermal and acoustic insulation of buildings made of glassy solidified fibers which are mostly thermoset with small amounts Binder are interconnected. Due to the chemical composition of the fibers is commercially available between A distinction is made between glass wool and rock wool. Because of the favorable processing properties Glass wool can be produced using the centrifugal blowing method become. Here, a glass melt passes through the openings of a rotating one Peel off. This procedure results in longer smooth ones Fibers that are laid flat on a conveyor belt. Glass wool is usually with about 5 to 8 mass% of a thermosetting Mixture of phenol-formaldehyde-urea resins bound. For The fiber mass with approx.
  • Insulation materials made from glass wool have one of them laminar structure with predominantly horizontal storage of the Monofilament on. This structure depends on the bulk density and the binder content and the uniformity of the binder distribution to structures with high tensile strength parallel to the large surfaces and low transverse tensile strength or, on the other hand, high compressibility. There are relative movements between the horizontal fibers possible so that the structures when winding up usually not be damaged.
  • Glass wool insulation materials with bulk densities ⁇ 25 kg / m 3 are available on the market both in the form of boards and in the form of rolled-up insulation felts (non-woven fabrics).
  • the rolled insulation felts are compressed to reduce the specific volume by approx. 40 to 60% compared to the original thickness. After unrolling, the nominal delivery thickness must be reached again, whereby certain tolerances are permissible.
  • Such insulation felt is known for example from DE 36 12 587 C2. This known insulation felt should have a bulk density between 10 and 40 kg / m 3 and an increased binder content of 6 to 7% by mass.
  • such insulation felt should be windable and thus flexible on the one hand, but on the other hand also have the property that a section deflected by the insulation felt has sufficient rigidity so that this section can be clamped, for example, between the rafters of sloping roof constructions and lasts there at least until supporting foils or strips are immediately applied to the underside of the rafters.
  • non-woven fabrics made from rock wool fibers consist.
  • Such insulation materials mostly consist of relatively short, often in curved fibers that are only approx. 2 to 2.5% by mass thermosetting Resin mixtures or the like are bound.
  • the structure of the rockwool nonwovens considered here depends on the manufacturing process, but especially the methodology the fiber collection.
  • the generally shorter ones compared to glass wool monofilaments Fibers in stone wool nonwovens can be transported directly on a conveyor belt are collected until the for the thickness of the insulation equivalent height is reached.
  • the taking into account several aspects technically better solution is to collect the fibers than pull off the thinnest possible primary fleece and then this on another conveyor belt, for example with the help of a pendulum device to be stored in such a way that the necessary Height and longitudinal compression equivalent deposit heights reached become.
  • the usual leveling transversely to the direction of transport results an inclined storage of the primary fleece layers.
  • To achieve distribution of the fibers will be a high number of primary nonwoven layers sought per unit volume.
  • the surfaces reorient the monofilaments. Besides, will reduces the adhesiveness of the binder present in the fiber mass.
  • the interfaces affect the mechanical properties the insulation structure as potential weak areas.
  • Nonwovens made of rock wool fibers are essentially in the direction of the three Major axes relatively stable against pressure, so that less compressibility compared to nonwovens made of glass fibers.
  • Farther nonwoven fabrics made of stone wool have one compared to nonwoven fabrics Glass fibers lower transverse tensile strength in the production direction, so that the winding of nonwovens from rock wool fibers in particular high bulk density of the nonwoven fabric is problematic. To wind up nevertheless to enable and the high risk of tears in the tensile zones of the To reduce insulation wrap, it is therefore common to make nonwovens Rock wool fibers with tensile films, paper or composite materials conceal.
  • Nonwoven fabrics There are various winding devices for the winding process of a nonwoven fabric known.
  • the usual wrapping technique for nonwovens is that the unloaded non-woven fabric remains unchanged on a conveyor belt conveyed to a winding station lying in the production direction is usually from a conveyor belt running obliquely upwards consists.
  • a pressure roller can be used to elasticize the nonwoven or a pair of pressure rollers can be arranged in front of the winding station.
  • the structure of the nonwoven fabric can also be damaged in this way be that the fiber tears already when winding or after Unrolling falls apart on site.
  • the fiber With the usual wrapping technique, the fiber is from the top running band and abruptly at an angle of more than 100 ° bent.
  • the pendulum suspended and guided by pressure cylinders Tape pulls the nonwoven section with it and presses it at the same time back on the incoming fiber fleece, so that this due to the high friction begins to roll up.
  • the nonwoven is additional heavily sheared. Further shear forces are exerted on the outer zones of the nonwoven fabric already under tension exercised that the nonwoven fabric is strongly compressed and at the same time the force causing the winding process is transmitted.
  • the introduction of force is on a relatively small area of the outer surface limited.
  • the pressure and shear forces have to be high to achieve compression from 50 to 70% in the core, to average over the entire roll of insulation to achieve from 40 to 60%. Added that by the enlargement of the roll diameter during the winding process too the leverage of the reel increases so that the wrap is temporary takes on an elliptical shape that leads to locally very narrow radii of curvature leads.
  • the covered nonwoven usually becomes solid with one another glued to the not inconsiderable expansion pressure of the winding compensate.
  • an adhesive is preferably applied transversely to the running direction applied to the wrapping.
  • To the individual layers of the nonwoven to press firmly against each other and for the strength development of the The winding process will allow glue required reaction time continued.
  • this procedure leads to considerable stress of the nonwoven, especially in the area of the partial areas immediately before the end of the insulation sheet. In this area Depending on the initial thickness and degree of compression, the nonwoven becomes considerable stressed on shear, so that with insufficient tensile strength the nonwoven tears open.
  • the expansion pressure within the roll causes the above described temporarily elliptical shape of the winding in the connection to the winding process into a round shape of the winding in cross section is transferred.
  • this expansion pressure also leads to permanent stress the area of the nonwoven, which acts as a clamping point of the nonwoven acts.
  • the invention has for its object to further develop a generic device in such a way that gentle winding of the nonwoven fabric is possible without large forces occurring in particular in the tension zones, which lead to damage or destruction of the nonwoven fabric, fiber nonwovens that have a high bulk density should also be able to be wound.
  • the deflection device has a guide element in the form of a band, which rotates at least around a first roll and around a second roll, the first roll at least in the area of the entry of the nonwoven fabric into the winding station and the second roll a length-adjustable arm is arranged, which is pivotable about the center of the winding station, so that the belt lies in extension of the conveyor belt with a strand on the outside of the large surface of the nonwoven fabric in the winding.
  • the nonwoven is accordingly deflected guided with the guide element of the deflection device, wherein a sudden turn with sharp-edged bends essentially is avoided.
  • the invention enables Device a winding process in which there is no free expansion or sharp local compression of the nonwoven fabric in front of or in the winding station is coming.
  • the guide element in the form of a band runs around a first role and a second role, the first roll in the area of the entry of the nonwoven into the winding station and the second roller is arranged on at least one variable-length arm is.
  • the first roll is thus on that of the winding station facing end of the conveyor belt, whereas the second role a circular path is movable so that the second roller with the tape the outer surface of the nonwoven lies in the roll and is guided is moved around the center of the winding station.
  • the deflection device consequently has a guide element in the form of a band, which at least around a first role and a second role. In principle both roles can be arranged movably. But there is also the possibility of the first roll in the area of the inlet of the nonwoven to be fixed in the winding station if one or more additional Rolls or a tape or multiple tapes are arranged ensure secure guidance of the nonwoven.
  • Tape is guided over at least one, in particular several tensioning rollers, which are both radial and at least partially tangential to the winding are movable. Due to the tension rollers, the belt can do the necessary Form for gentle guiding of the nonwoven fabric in the winding station be specified. The partially radial mobility of the tension pulleys serves to adapt the same to the increasing diameter of the resulting wrap.
  • the second role between two length-adjustable, in particular telescopic Arms is arranged, which arms on both sides of the conveyor belt or the winding station are arranged.
  • This configuration has the advantage that there is overall a more stable construction of the deflection device results.
  • the role here extends over the maximum Width of the nonwoven to be wrapped, with nonwovens with less Widths can be wrapped in the device.
  • a rotation device for receiving is preferably located in the pivot point of the arm a winding core arranged. It is provided that the Nonwoven is wound over a core.

  • the core can in Cross-section round, square, polygonal or flattened in one place be trained. Such cores can be made in one or two parts the two-part core has proven to be advantageous, because it has a relatively short path from both sides into the rotating device can be inserted.
  • the sections of the core are cut from before the winding process begins both sides pushed through a hollow axis of the rotating device.

Alternatively, it can also be provided be that the core out after the winding process the wrap is pulled out.
  • the distance depending on the first role and the second role the material thickness and / or a compression to be achieved in the winding the fiber fleece or changeable depending on the winding progress is. This ensures that the nonwoven fabric is removed from the conveyor belt enters the winding station constantly on the same level without that as the winding progresses, the compression in the nonwoven fabric increases.

  • the circulating belt serves as well Swiveling the arm around the winding core the frictional Transport of the nonwoven.
  • Conveyor belt speed is adjusted. Basically, the Belt speed versus conveyor belt speed reduced so that the conveyor belt is slightly higher Conveyor speed than the belt has. It follows that the nonwoven in a slightly compressed condition, d. H. under minor Pressure enters the winding station. This upsetting leads to at least one partial compensation of the tensile stresses in the Wrap outer areas of the nonwoven fabric so that essentially Damage or destruction of the fiber structure avoided become.
  • the axes of rotation of the Winding core and the second roll by at least one material thickness of the nonwoven moved apart to the next layer of the nonwoven without additional pressure or tensile stress in the winding station to come in.
  • the Conveyor belt is arranged opposite a printing belt, which the free-running nonwoven compresses. By partial or complete Compressing the fiber fleece will improve elasticity of the nonwoven.
