Definitions

  • the present invention relates to an improved apparatus for rolling up compressible fibrous materials.
  • the invention relates to formation of rolls starting from bands or ribbons of compressible fibrous materials such as mineral-fibre felts intended for use typically in the building field for heat insulation and/or soundproofing of walls, attics and so on.
  • mineral-fibre felts such as felts made of glass wool
  • felts made of glass wool are widely used for heat insulation or soundproofing purposes in a variety of fields and, as above mentioned, they particularly apply to the building field.
  • the glass wool felt thickness is required to be maximum during setting up, so as to ensure high performance in terms of heat insulation/soundproofing and, on the other hand, there is an opposite requirement of minimizing the volume taken up by the felts in order to enable an easy and cheap transportation of same.
  • the felt thickness should be reduced as much as possible even if, on the other hand, the springing-back capability of the product, when the latter is disengaged from package and then installed, is to be taken into due account too.
  • the glass wool ribbon is conducted through a space delimited by two conveyor belts and a pressure roller.
  • the conveyor belts are inclined and converge towards each other so as to define a predetermined solid angle
  • the pressure roller is disposed within the solid angle formed by the two above mentioned belts at a given distance from the ideal corner defined by the latter.
  • the conveyor belts and roller draw the felt in a rotation movement about itself.
  • the pressure roller is displaced in such a manner that the space in which the glass wool roll is being formed progressively increases.
  • the pressure roller is suitably counterbalanced and is allowed to move freely during formation of the glass wool roll (packaging by passive compression), or it is moved by appropriate drive means and control members following a law previously set by the apparatus (rolling up by active compression).
  • apparatuses provided with an active control on the pressure roller are capable of performing a continuous adjustment of the action exerted by the roller on the felt, so that an as much as possible uniform compression and felt processing is carried out during the whole rolling-up operation.
  • a rolling-up apparatus providing an active compression control is disclosed widely and in detail in European Patent No. EP-0 140 785, to which please refer for further details.
  • rolling up is controlled by an active intervention of the pressure roller imposing a predetermined thickness, which is preferably constant or slightly decreasing during rolling, to each coil of the felt being rolled up, in order to substantially achieve a uniform compression over the whole felt length, so that, during the installation step, a product having a uniform spring-back and, as a result, constant insulation features over the whole longitudinal extension thereof, is correspondingly obtained.
  • a predetermined thickness which is preferably constant or slightly decreasing during rolling
  • an improved apparatus for rolling up compressible fibrous materials in accordance with the present invention has been generally identified by reference numeral 1.
  • apparatus 1 will be adapted for use in rolling up materials such as mineral-fibre ribbons or bands, felts made of glass wool for example.
  • Apparatus 1 comprises at least one conveyor member 2, and at least one deflection member 3, preferably consisting of respective conveyor belts such disposed as to define a solid angle ( ⁇ ) of predetermined opening. More specifically, as shown in the accompanying drawings, the conveyor belt 2 has a corresponding operating stretch 2a, the horizontal one in this case, over which the ribbon of compressible fibrous material 4 to be rolled up is placed. In turn, the deflection member or belt 3 operates at an end region 2b of the conveyor belt 2 and has a respective operating stretch 3a directly in contact with the roll being formed and defining said angle ( ⁇ ).
  • a restricting member 5 Operating at this solid angle is a restricting member 5, consisting for example of a roller (see the accompanying figures) or a conveyor belt (not shown); the restricting member 5, in cooperation with the conveyor member and deflection member, defines a rolling-up space 6 for the compressible fibrous-material ribbon which, by virtue of the movements imparted by said members 2, 3, 5, can be coiled up, thus progressively increasing its diameter, as better clarified in the following of the present description.
  • the restricting member 5 is operatively connected to first drive means 7 moving this member away from an ideal corner 8 defined by angle ⁇ , at a predetermined displacement speed Vs.
  • the restricting member 5 is radially movable relative to the roll being formed, following a trajectory constantly lying in a flat surface 9 bisecting the solid angle ⁇ .
  • Apparatus 1 is also provided with an auxiliary unit 10 for feeding sheet material 11 suitable for carrying out final packaging of the roll, once the latter has reached the desired diameter sizes.
  • apparatus 1 comprises detecting means 12 which can be associated with the conveyor member and/or deflection member and/or restricting member.
  • the detecting means 12 is arranged to generate a signal 13 proportional to the reaction load transmitted by the roll being rolled up onto the respective one of said members 2, 3, 5; a control unit 14 cooperates with the detecting means 12 and is active on its own drive means 7 to vary the displacement speed Vs of the restricting member 5 depending on signal 13 generated by the detecting means 12 in accordance with a preset law.
  • the detecting means 12 is operatively associated with at least one of said members 2, 3, 5, the conveyor member 2 for example, and is capable of detecting the reaction load transmitted by the roll to the conveyor member, thereby generating an output signal 13 proportional to the amount of said load.
  • reaction load lying, for example, on the conveyor member will be partly due to the weight of the material being gradually wound up and partly due to the force, and therefore pressure, that the restricting member 5 exerts on the fibrous-material roll as the latter is being formed.
  • the detecting means may comprise at least one load cell 15, 16, 17 placed close to the conveyor member 2 and/or deflection member 3 and/or restricting member 5 and capable of outputting a signal 13 proportional to the reaction load transmitted by the roll being wound up to the corresponding one of said members provided with the load cell itself.
  • the load cell or cells used will be interposed between the concerned deflection, conveyor or restricting members and a fixed support. It should be noted that generally use of several load cells is preferred, which cells are usually disposed at the conveyor member 2 and have offset positions relative to each other.
  • the load cells 15 are at least two in number (see Fig. 2), spaced apart from each other transversely of the ribbon 4 of compressible material to be rolled up and put close to the conveyor member at a region 18 substantially underlying the rolling-up space of the ribbon itself.
  • load cells 15, 16, 17 must substantially give a response proportionate to the load transmitted by the restricting member to the roll being processed, installation of these load cells is advantageously provided at a region defined by displacement of the restricting member from its minimum-distance condition from corner 8 (beginning of winding-up) to its maximum-distance condition from the same corner of the solid angle (end of winding-up).
  • the conveyor member 2 which, as said, preferably consists of a conveyor belt, is moved by second drive means 19 at a peripheral speed Vp1 of contact with the fibrous material which is preferably substantially constant.
  • the deflection member 3 also preferably consisting of a conveyor belt, is moved by third drive means 20 at a peripheral speed Vp2 of contact with the fibrous material which is preferably substantially constant.
  • the restricting member which in its practical accomplishment may consist both of a roller and of a conveyor belt moved at a substantially constant peripheral speed Vp3 of contact with the compressible fibrous material ribbon.
  • the restricting roller or belt in addition to being moved away from the corner of the solid angle ⁇ by the first drive means 7 at a speed Vs, is also moved around its own axis at the peripheral speed Vp3 by fourth drive means 21 associated therewith.
  • the detecting means 12 of apparatus 1 may comprise an energetic-absorption sensor 22, 23, 24 associated with the above mentioned second and/or third and/or fourth drive means for example, so as to pick up the energetic consumption therefrom which is necessary for keeping the peripheral speed Vp1, Vp2, Vp3 of the respective members always constant.
  • the load transmitted by the restricting roller or belt 5 to ribbon 4 can become known and therefore be adjusted by for example evaluating the energetic absorption required by the second drive means 13 to keep the peripheral speed Vp1 of the conveyor belt 2 constant. It is in fact apparent that the resistance to movement offered by the conveyor member 2 is linked to the load lying thereon and therefore to the pressure exerted by member 5 onto the roll being formed.
  • the detecting means in accordance with the present invention may comprise a combined solution including load cells and energetic-absorption sensors in order to send the control unit 14 several signals 13 which at all events are all linked to the load transmitted by the restricting member 5 to the ribbon being wound up.
  • the control unit will then be such programmed as to manage movement (i.e. speed Vs) of the restricting member 5, so that the load transmitted instant by instant to the ribbon being wound up may comply with a preset law.
  • control unit will operate the first drive means by varying the displacement speed Vs of the restricting member, so as to keep the reaction load transmitted by the restricting member to the roll substantially constant during most of the winding-up operation.
  • apparatus 1 further comprises a precompression device 15 operating upstream of the rolling-up space 6 relative to the feeding direction of the compressible-material ribbon.
  • the precompression device 15 is capable of causing a predetermined compression on the fibrous-material ribbon 4 before the latter comes to the rolling-up space 6.
  • the precompression device comprises a conveyor belt 13 active on the fibrous material on the opposite side relative to the operating stretch 2a of the conveyor member 2.
  • This precompression device in particular has an active portion 25a operating on the fibrous material and exerting a compression action thereon, which is directed perpendicularly to the predetermined feeding direction of the fibrous material itself.
  • the operating stretch 2a of the conveyor belt 2 is rectilinear and converges towards the active portion 25a, which is rectilinear as well, of device 25, moving close to the rolling-up space 6.
  • the operating stretch of the conveyor member and the active portion 25a of the precompression device define a precompression acute angle ⁇ .
  • the active portion 25a of the precompression device has a peripheral speed Vp4 having a component (p), parallel to the peripheral speed Vp1 of the operating stretch 2a of the conveyor belt 2, and a component (o), perpendicular to the peripheral speed Vp1 of the operating stretch 2a of the conveyor member.
  • the parallel component (p) is in particular of same modulus, direction and way as the peripheral speed Vp1 of the operating stretch 2a of the conveyor member 2, so that the device 25 does not exert any tangential action on the compressible-material ribbon, which action could cause undesired delaminations.
  • movement means (not shown) associated with the precompression device can be provided for moving said precompression device close to and away from the rolling-up space and/or for moving this device in a manner adapted to vary the width of the precompression angle ⁇ .
  • the control unit 14 is active on the movement means to progressively move the precompression device away from the rolling-up space as the material is coiled up, so that a distance d between the perimetric edge of the roll being wound and the precompression device is maintained substantially unchanged.
  • the invention achieves important advantages.
  • load detections load cells
  • energetic-absorption detections as to instantaneoulsy supply the control unit 14 with a reliable control signal
  • the apparatus Since a compression device operating upstream of the rolling-up space and cooperating with the detecting means and the control unit has been provided, the apparatus is also very advantageous for achieving an excellent packaging with a high percentage of compression of the processed ribbon, the geometry of the roll being always respected.
