Definitions

  • the present invention relates to an 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 although, 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 led 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 information.
  • 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
  • the pressure roller in addition to exerting a given radial action on the coils of the fibrous material, certainly also exerts a tangentially-directed strong action. This inevitably gives rise to tangential stresses at the contact areas between the fibrous material and the pressure roller surface, which stresses very often cause delaminations of the fibrous material, breakage of many fibres and, as a result, a substantial incapability of springing back of the material at the delamination regions.
  • an 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, such as felts made of glass wool.
  • 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 (Y) of predetermined opening.
  • the conveyor belt 2 has a corresponding operating stretch 4a, the horizontal one in this case, over which the ribbon of compressible fibrous material 5 to be rolled up is placed.
  • the deflection member (belt) 3 operates at an end region 2a of the conveyor belt 2 and has a respective operating stretch 4b defining a solid angle (Y) with the mentioned operating stretch 4a; a roller 6 is disposed within the angle (Y) and, in cooperation with the conveyor belt 2 and deflection belt 3, it defines a rolling-up space 7 inside which a roll 8 of fibrous material is being gradually formed.
  • the conveyor belt 2 causes movement of the compressible fibrous material 5 in a predetermined direction and feeding speed, diagrammatically shown by arrow 9, towards the rolling-up space 7.
  • the above mentioned roller 6 moves away from the ideal corner 10 of the solid angle (Y) defined by the conveyor belt 2 and deflection belt 3.
  • roller 6 placed inside the solid angle (Y) is rotatable about a rotation axis 11 orthogonal to the feeding direction 9 of the fibrous material 5 and parallel to the ideal corner 10 defined by the solid angle extending between the conveyor belt 2 and deflection belt 3.
  • the rotation axis of roller 6 is substantially parallel to the ideal rolling-up axis of the fibrous material.
  • apparatus 1 also comprises a precompression device 12 operating upstream of the rolling-up space 7 relative to the feeding direction 9 of the fibrous material being processed 5; the precompression device 12 is active on the compressible fibrous material ribbon to cause a predetermined compression of said ribbon before it comes to the rolling-up or packaging space 7.
  • the precompression device 12 operates close to the conveyor belt 2 and is active on the fibrous material on the opposite side relative to the operating stretch 4a of said conveyor belt.
  • the precompression device comprises at least one conveyor mat 13 having at least one portion 13a active on the fibrous material and exerting a compression action thereon, which action is directed perpendicularly to the feeding direction (see face 9) of the fibrous material towards the rolling-up space 7. More specifically, the conveyor mat 13 of the precompression device has a rectilinear active portion 13a converging towards the operating (rectilinear too) stretch 4a of the conveyor belt 2, as the ribbon moves closer to the rolling-up space 7.
  • an acute precompression angle ⁇ is formed between the active portion 13a of the conveyor mat 13 and the operating stretch 4a of the first conveyor belt 4, which angle fundamentally defines the percentage of maximum compression to be imparted to the material being processed.
  • movement means (not shown) adapted to angularly shift said mat so as to vary said precompression angle ( ⁇ ) may optionally be associated with the conveyor mat itself (see Fig. 2).
  • the active portion 13a of the precompression device 12 is moved at a peripheral speed V1 of contact with the material being processed having a component V1p parallel to the peripheral speed V2 of the operating stretch 4a of the conveyor belt 2 and of same modulus, direction and way as the speed V2 of stretch 4a.
  • the peripheral speed V1p of the active portion 13a of the precompression device also has a component V1o orthogonal to the peripheral speed V2 of the operating stretch 4a of the first conveyor. This orthogonal component V1o will have a modulus to be fixed depending on requirements and in particular on opening of angle ( ⁇ ).
  • the precompression device does not substantially exert any tangential action on the material to be packaged.
  • the movement means associated with the precompression device 12 can also include slides or similar devices for advantageously moving the device itself away from the rolling-up space 7, as the material is wound in a roll (see Fig. 1).
  • the movement means will be managed by a control unit for moving the precompression device 12 away from the packaging space and keep a minimum distance d between an outer perimetric edge 8a of the roll being packaged and the precompression device, constantly unchanged.
  • the first conveyor belt 2, the deflection belt 3 and the conveyor mat defining the precompression device can be activated by respective power units 14, 15, 16 or by a single power unit after interposition of kinematic connecting members, depending on the practical and construction requirements that are each time present.
  • the power unit or power units active on the conveyor belts and conveyor mat suitably managed by a Central Processing Unit (CPU) 17, will be adapted to enable the peripheral speed of the different conveyors to be varied so as to obtain particular production rates or compression control effects in accordance with laws set in by the user during rolling up.
  • CPU Central Processing Unit
  • roller operating within the solid angle (Y) defined between the first and second conveyors is constantly guided in such a manner that it exhibit its rotation axis constantly disposed at the flat surface 18 bisecting the same above mentioned solid angle.
  • this roller can be counterbalanced by substantially exerting a constant compression action without particular and accurate electronic managements being required, because the compression control of the ribbon during rolling up substantially relies on the precompression device 12.
  • the apparatus in reference comprises at least one auxiliary unit 19 for feeding sheet material 20, which operates above the first conveyor belt 2, for example.
  • Unit 19 is shiftable from a non-operating condition to an operating condition in which this auxiliary feeding unit is capable of sending a sheet material such as paper or plastic film, to the packaging station to carry out a final packaging of the fibrous-material roll, once the latter has reached the desired radial sizes.
  • the invention achieves important advantages.
  • the precompression device consisting of a conveyor mat the speed of which can be such managed, in terms of modulus and direction; that a mere compression action on the compressible material to be rolled up is exerted, said material is not submitted to any delamination action and can be packaged at high precompression values without any structural damage.
  • the apparatus in reference can be easily installed and fundamentally enables the whole compression action to be exerted upstream of the packaging space, an active and constant managing of the compression exerted by roller 6 operating between the first and second conveyor belts being substantially unnecessary.
