Definitions

  • the invention relates to techniques for compressing and then winding fibrous mats to allow their wrapping and conditioning up to their place of use.
  • Flexible fibrous mattresses in particular those made of glass wool or rock wool intended for insulation, are most often wound on themselves very tightly to prevent them from occupying too much volume important during their transport. The higher the compression ratio of the fibrous mat, the cheaper the transport and storage.
  • the production lines operate continuously and deliver mattresses of uninterrupted length. These are cut to form rolls whose width and length correspond to the needs of the user. On the production lines of insulating wool mattresses there are winders whose operation is more or less automated.
  • these machines To perform their functions, these machines must have a number of basic characteristics. They must compress the woolen mattresses as much as possible and this in the same way over their entire length but they must also avoid damaging the fiber and the binder which constitute the insulating mattress.
  • One mission that the invention sets itself is precisely to provide a winder whose downtime is reduced to a minimum.
  • An object of the invention is to provide fibrous mattresses wound on themselves with high compression ratios and which find all their original characteristics on decompression.
  • An object of the invention is also to provide a winder which in no way degrades the fibers and the binder of the fibrous mat during compression.
  • the rolls of mineral fiber mattresses which it is possible to obtain with the rewinders of the prior art are limited in the case of specific masses of 8 to 10 kg / m3, at compression rates of less than 7/1 if the compression is carried out in a single operation and at rates of between 6 and 8/1 with the methods comprising two mechanical steps or a mechanical step and a vacuum step.
  • a winder of the first type is described for example in patent EP 294 290. It comprises two flat conveyor belts associated to form a dihedral which is in permanently tangent to the fibrous roller in formation. The compression of the fibrous mattress is exerted by a movable roller whose position and speed of rotation obey precise laws.
  • This type of winder has two types of drawbacks. First of all, the pressure is exerted on the fibrous roller in formation only in well-defined places. Between these compression zones, the fibrous mat relaxes to be compressed again a little further. This alternation of pressure / depression on the fibers can cause them to break and moreover the binder which associates the fibers with one another undergoes fatigue which can cause its deterioration in places.
  • the second drawback of this type of winder lies in their discontinuous operation. At the end of the winding operation of a first fibrous roller, the pressure roller must be spread so as to allow the ejection of the fibrous roller and it is only after its return that the following priming operation of the winding of a new fibrous roll can take place.
  • a second type of winder has been developed. He uses to press on the fibrous roller either a free mat or two groups of belts which form a sort of circular cavity around the roller.
  • the invention relates to a roll of compressed insulating mattress based on mineral fibers and a specific mass at the origin of 8 to 10 kg / m3, the compression ratio of which is at least 8.5 to 1.
  • the subject of the invention is therefore a winder for winding a flexible band around itself and in which the roller in formation is rotated by two flexible means which each enclose a part of the circumference of the roller in formation and which are guided and driven by appropriate means in order to adapt to the magnification of said roller in formation (see US-A-4,034,928).
  • the flexible strip is a fibrous mattress compressed by compression means before winding, and the flexible means are carpets which encircle one substantially half the circumference of the forming roller and the other a substantial part of the remaining half.
  • the subject of the invention is also the rolls of compressed insulating mattresses based on mineral fibers obtained by this type of winder, and in particular having a compression ratio of at least 8.5 to 1.
  • the evacuation of the roll of the compressed mattress is carried out in the same direction as the introduction of the compressed fibrous mattress.
  • the compressed fibrous mattress is obtained by compression without sliding of the fibrous mat between pressing members which are preferably between two conveyor belts.
  • a device such as a metal plate keeps the fibrous mat compressed between its exit from the pressing members and its contact with the preceding turn of the roll in formation.
  • the compressed mattress is introduced substantially tangentially to the periphery of the roller being formed.
  • At least three of the four rollers which guide the two belts are tangent to a cylinder whose director has substantially the shape of a spiral corresponding to the theoretical envelope of the compressed roller. at the same time.
  • two of the four preceding rollers, located downstream of the machine are replaced - at the moment when they release the finished roll - by two new rollers whose progression is carried out in the same direction as the downstream rollers.
  • the four rollers are associated two by two with rotating systems of the carousel type which support them.
  • the fibrous mattress roll of the invention with high compression ratio allows significant savings to be made during the transport and storage of the insulating blankets.
  • the technique of the invention makes it possible to exercise weighting the winding at a constant pressure both in time and in space, thus avoiding the back and forth compression and depression which degrade the fibers and cause fatigue of the binder.
  • the fact of passing the device according to the invention through the fibrous roller rather than exerting a back and forth movement also makes it possible to reduce downtime very significantly.
  • Figure 1 we see the essential elements of the device of the invention.
  • a first conveyor belt whose conformation varies throughout the winding operation. It is the same for the second conveyor belt 2.
  • the support rollers have been shown with circles around their axes. treadmills, the position of which does not change during the entire winding operation.
  • the rollers whose axes are represented by crosses in broken lines have their position which changes during the duration of the winding of the fibrous mat.
  • the two plane elements 5 and 6 move at substantially the same speed which is the speed of exit of the mattress fibrous 4 of the production line.
  • This part of the device therefore makes it possible to avoid any relative movement between the fibrous mattress and therefore the fibers of the fibrous mattress on the one hand and the carpets which compress them, on the other. This avoids everything friction which would risk damaging said fibers.
  • the flat part 5 of the treadmill 1 is actually supported by a second treadmill 8, the upper part of which supports the straight part 5 of the treadmill over its entire length. It is advantageous to use this conveyor belt 8 not only to support the treadmill 1 but also to train it in its translational movement.
  • the roller 9 is therefore advantageously used to drive both the conveyor belt 8 and the conveyor belt 1.
  • the rotational movement of this roller 9 has a constant speed during winding.
  • the conveyor belt 2 it is driven by one of its support rollers upstream of the cavity, for example the roller 10. Its speed is also constant during the winding.
  • the tension of the conveyor belts 1 and 2 is provided respectively by the roller 11 and by the roller 12, the position of which is controlled by the central computer at all times.
  • the cavity in which the compressed fibrous mat is rolled up is defined by five rollers and two conveyor belt elements. Among the two rollers are fixed: the roller 9 which has already been discussed and the 13 which guides the treadmill 2.
  • the rollers 14 and 15 respective supports of the treadmills 1 and 2 move in two paths parallel rectilinear so as to release a length of mat respectively 17 for the mat 1 and 18 for the mat 2 which will serve to form the circular wall of the cavity where the compressed mattress will be rolled up.
  • the small movable roller 16 exerts a particular function at the start of the operation.
  • the roller 16 occupies a position which allows the end of the mattress 19 to penetrate very far into the cavity. This position is determined by the thickness of the mattress to be rolled up.
  • the purpose of the roller 16 is to close the cavity at the start of winding and to allow the formation of the first turn.
  • the position of the roller 16 is fixed.
  • the rollers 14 and 15 begin to move to the left of the figure in the direction of the roller 10 and its twin roller 20.
  • This movement is also managed by the computer so that the four rollers 9, 14, 15 and 13 occupy the theoretical position at the periphery of the compressed fibrous mattress, that is to say that they are tangent to a cylinder with a spiral director.
  • the computer calculates the theoretical dimension to be given to the cylinder with spiral director which constitutes the periphery of the compressed roller. This dimension depends on the one hand on the compression coefficient which it was decided to apply to the mattress, therefore finally on its thickness in the compressed state and on the other hand on the length of mattress already rolled up.
  • the rollers 9 and 13 being fixed, it is the position of the rollers 14 and 15 which defines the cylinder in question, the length of the curved walls 17 and 18 of the cavity being defined by the position of the tensioning rollers 11 and 12, determined it - even by computer.
  • the packaging of the compressed roll is carried out simultaneously with the winding of the last turn of compressed mattress.
  • the same materials as usual are used for packaging, such as kraft paper, plastic films, for example polyethylene.
  • the strips of film intended to package the products are pre-cut and pre-glued.
  • the next step is to eject the wrapped roll. It is shown in Figure 3 where we see a general movement of the carpet 1 driven by the roller 20 which was hitherto stationary and which this time moves down to free the passage to the compressed and packaged roller 23 which occupies the position 24 on the conveyor 25 which discharges it. As soon as the roller 23 has left the reel, the belt 1 driven by the roller 20 comes back to the position it occupied at the start of the operation in FIG. 1. The rollers 14 and 15 also come in their original position and the operation can start again immediately. It is thus seen that the dead time which separates the end of the winding of a first roll and the start of the winding of the next roll is very reduced since in the device represented in FIGS. 1, 2 and 3 it suffices that roller 20 moves away from roller 10 and then returns to its original position while rollers 14 and 15 also make the return journey. This can be done in fractions of a second.
  • FIG. 4 and FIG. 5 show a variant of the invention which uses two carousels, respectively 26 and 27, to obtain the movements of the support rollers for the belts 1 and 2.
  • Each of these carousels has two cheeks between which are fixed. rollers which will in turn support the belts 1 and 2.
  • Each of the carousels' cheeks has three radial arms located at 120 ° from each other. At the ends of these arms are fixed levers which in turn carry at their ends the rollers which support the belts 1 and 2. The levers deviate more or less from the axis of the carousels by means of jacks. Only one of the three rollers on each carousel is active at any given time. In the figure these are the rollers 28 and 29.
  • rollers 28 and 29 are supported respectively by the levers 30 and 31, actuated by the jacks 32 and 33, and themselves supported by the radial arms 34 and 35.
  • the function and the movement of the rollers 28 and 29 is exactly the same as that of the rollers 14 and 15 of FIG. 1.
  • the two carousels 26 and 27 are driven in a synchronous movement but their speed is not constant. It is such that, as before, the rollers 9, 13, 28 and 29 are in a position such that the belts 1, 2 constitute the theoretical figure which defines the compression of the fibrous mattress wound on itself. If the rollers are of small diameter, they can be all four tangent to this theoretical figure otherwise, as in the figure, only three are.
  • the driving rollers are the roller 9 for the belt 1, the roller 39 for the conveyor belt 7, and the roller 38 for the belt 2.
  • the speed of these three rollers is constant, as for the rotational speed of the two carousels and the position of the two jacks 32, 33 and so on that the position of the tension rollers 11 and 12 is determined by the central computer of the device.
  • FIGS. 4 and 5 therefore has the advantage of allowing two pairs of rollers 36 and 37 to succeed immediately without dead time the rollers 28 and 29 which have just escaped from the other side.
  • a device which makes it possible to maintain the pressure on the compressed mattress between the place where it leaves the upper presser belt 7 and the place where contact with the previous turn 41 is established. It is for example a metal plate supported by a flange which passes between the rollers 39 and 13.
  • the table presents the results obtained.
  • the most spectacular progression concerns time packaging, this is due to the fact that the reel of the invention performs it in masked time, in other words the packaging is carried out at the same time as the winding of the last turn of the compressed mattress.
  • the compressed roller of the invention with for the first time, compression ratios higher than 10/1 obtained directly on the rewinder without deterioration of the mattress which regains its thickness and its original qualities present compared to the rollers of the prior art the advantage of savings on packaging, transport and storage.
  • the reduced downtime of the machine, object of the invention makes it possible to reduce the necessary ratio between line speed and winding speed.
  • This ratio was so far from 2 to 2.5 and it decreases to 1.3-1.5 on the new machine.
  • This allows either to wind a given product for a given line speed at a lower winding speed and therefore further improve the quality of the winding, or to wind a given product at a winding speed (which can reach 200 m / min) higher than the maximum speed allowed so far (150 m / min). This saves on investment.
