Definitions

  • the present invention relates to the formation and conditioning of felts of fibrous insulating products, in particular based on mineral fibers.
  • a fiber mattress of mineral fiber is produced as a result of various steps at the exit of a forming device in which the mattress has been compressed and heated to cause the polymerization of a binder encapsulating the fibers.
  • the mattress thus obtained continuously is conveyed on a conveyor device and generally has a large width of up to several meters, for example 3.6 m. For its use, it is necessary to cut defined lengths and widths less than the width of manufacture to obtain felts whose dimensions are for example 31 cm wide and 1.2 m long.
  • the mattress at the output of the forming device is cut longitudinally and along its median line to generate two mattresses of equal width which are driven by bifurcating by means of two distinct conveyor belts. Subsequently, these mattresses will be called half-width mattresses.
  • a half-width fiber mat is in turn cut longitudinally into several strips, for example four, of equal width and corresponding to the desired width of the felt to be provided. These four strips are driven parallel to each other and undergo a transverse cutting operation to form the desired length felt by trimmers located vertically of each strip scroll.
  • each of the four strips consisting of the formed felts is diverted and conveyed by a conveyor to a compression and packaging machine.
  • This machine comprises a receiving device placed directly below the end of the conveyor to receive the insulating felts.
  • the The stack is transferred to a conditioning chamber for compression in the stacking direction, a film surrounding the stack. The film is then glued or welded on itself so as to surround the stack and the compression can then be relaxed.
  • the invention therefore proposes to manufacture and package insulating felts without requiring large means of transport, cutting and compression and packaging, thereby requiring a reduced workforce.
  • the parallel fiber strips on the conveyor device are deviated from their scrolling plane in directions rising and / or falling angular converging towards an axis perpendicular to the original scroll plane and at which said vertically spaced strips arrive coplanar.
  • the coplanar fiber strips are deposited by gravity on the receiving conveyor so as to superimpose them in an aligned manner in order to carry out the longitudinal stacking.
  • the stack Before transverse cutting of the compressed stack to obtain the felts, the stack is wrapped around its longitudinal and lateral faces.
  • the compression means drive with them during compression of the stack at least one packaging film for covering said longitudinal and lateral faces of the stack.
  • two packaging films are used to be applied against the longitudinal faces, then folded after compression of the stack against the side faces and interconnected by means of securing.
  • the fiber mattress at the outlet of its forming device When the fiber mattress at the outlet of its forming device is cut into two mattresses of identical width, it is provided that the fiber strips coming from the two mattresses bifurcate along two bifurcation and convergence devices to deliver on two respective receiving conveyors.
  • the two receiving conveyors being positioned to converge at their downstream end to a third receiving conveyor to ensure the superposition of the two stacks of strips according to a third final stack to be processed by the compression means.
  • the device for carrying out the method is characterized in that the bifurcation and convergence device comprises individual conveyor belts for each of the fiber strips, said conveyor belts having their starting point at the junction of the device. conveyor and in alignment with the fiber webs, and their arrival point aligned along a vertical axis and above the receiving conveyor.
  • guide flanges are provided on each side and at the upstream end of the receiving conveyor to ensure alignment of the stack.
  • the compression means consist of two convergent mats whose pressing surfaces are provided with packaging films for deposition on the longitudinal sides of the simultaneous compression stack.
  • cutting means are arranged downstream of the compression device for transverse cutting of the compressed and packaged stack.
  • mineral wool strips 10 which are well-known, by means of circular saws, not illustrated, of longitudinal cut-outs of two half-width mineral wool mattresses are visible.
  • the half-width mattresses are from a mattress split in two longitudinally when the final dimensions of the desired felts impose it; this is indeed the case for a mattress having at the output of its forming device a width of 3.6 m, the final felt to have a width of 0.31 m.
  • Each half-width mattress is cut into four mineral strips 10 which are supported and driven in parallel by a conveying device 2 moving horizontally in the direction of the arrow 3.
  • a horizontal cut to split in two the thickness of the mattress it is sometimes carried out in known manner, at the output of the forming device and downstream of the cut of the half-width mattress, a horizontal cut to split in two the thickness of the mattress . It is also possible to provide, simultaneously or just upstream of the blank, to cover the top and bottom faces 10a and 10b of the mat of a functional coating 10c, as illustrated in FIG. figure 1 at.
  • a bifurcation and convergence device 4 visible on the Figures 1 to 4 , is provided in interruption of the carrier device 2 for separately conveying the four mineral strips 10 in upward and downward angular directions with respect to the horizontal direction 3, and converging towards an axis A perpendicular to the horizontal plane of the conveying device 2.
  • the purpose of the bifurcation and convergence device 4 is to route the mineral strips 10, initially parallel to one another, to position them above each other in the same vertical plane.
  • the bifurcation device 4 consists of four conveyor belts 40 which originate at the junction of the device 2 along the axis of each moving mineral strip 10 and which end at their ends 41 vertically to a receiving conveyor 5.
  • the conveyor belts 40 are inclined angularly in a vertical plane perpendicular to the horizontal direction 3 so as to control the separation height between each conveyor belt in order to provide a sufficient space corresponding at least to the thickness of a mineral strip, the thickness of the strips being a function of the thickness of the mattress at the output of the forming device.
  • the conveyor belts 40 are also inclined angularly in a horizontal plane parallel to the horizontal direction 3 in order to adjust the position of the terminations 41 along the same vertical axis A at the level of the receiving conveyor 5.
  • the length of the conveyor belts 40 is adapted as a function of the running speed of the mineral strips 10, so that the four mineral strips 10 arrive perfectly coplanar at the terminations 41.
  • the receiving conveyor 5 accommodates the four mineral strips 10, which are superimposed one above the other to form a longitudinal stack and aligned 11 strips.
  • the superposition of the mineral strips 10 is carried out according to gravity sliding from the terminations 41 on the receiving conveyor 5. Consequently, the receiving conveyor is always located below the most angularly descending conveyor belt 40.
  • the convergent conveyor belts 40 are rising and falling relative to the plane of the conveyor device 2; alternatively, they could as well be all rising or falling as illustrated in FIG. figure 3 , the receiving conveyor 5 being positioned at the lowest point of the assembly.
  • flanges 50 visible on the Figures 2 to 4 are provided on the sides and at the upstream end of the receiving conveyor 5 to linearly guide, upon receipt, the mineral strips on the conveyor.
  • a compression and packaging device 6 visible to the figure 5 , is installed after the receiving conveyor 5 in order to compress the stack 11 of the four mineral strips and to surround it with a packaging film 7 for maintaining in compression and the subsequent conditioning of the felts to be obtained.
  • the compression and packaging device 6 comprises two conveyor belts 60 inclined and convergent downstream of said device.
  • each carpet 60 At the entrance of each carpet 60 is a supply system, not shown, in packaging film delivering two films 7.
  • the two films 7 have a width adapted to the overlap of the longitudinal surfaces 12 of the stack 11 and compressed than covering said films on the side faces 13 of the stack.
  • the films 7 are guided by non-illustrated rolls so as to come into contact respectively with each of the pressing surfaces of the belts 60 facing each other and intended to be pressed against the longitudinal faces 12 of the stack 11.
  • the threads are preferably driven by the movement of the belts 60, which ensures that the films are stretched longitudinally against the longitudinal faces 12 of the stack 11.
  • the belts 60 At the end of the compression zone, the belts 60 have their pressing surfaces parallel and spaced apart by a quantity that corresponds to the desired final height of compression of the stack 11, that is to say the felts to be produced.
  • shapers 61 whose role is to set up the edges of the films 7 against the side faces 13 of the stack, as well as securing means 62, including hot air nozzles which perform an autogenous welding of suitable plastic films, or by providing an external glue type hot melt for example or a double-sided adhesive.
  • cutter means 8 At the outlet of the compression and packaging device 6 are cutter means 8 of the cutter type whose role is to cut transversely the stack 11 of the mineral strips to make the felt to the desired length.
  • the final packaging felt is achieved by means of a traditional machine that stacks a determined number of felts and envelopes.
  • the half-width mattress of mineral fibers is delivered on the conveyor device 2; while progressing in the direction 3 it is cut longitudinally by to be converted into several parallel mineral strips 10 between them.
  • the conveyor belts 40 of the bifurcation and convergence device 4 angularly deflect upwardly and downwardly each of the fiber strips 10 so that the latter arrive at the terminations 41 of the conveyor belts in a vertical alignment.
  • the mineral strips 10 then leave the terminations 41 and are deposited by gravity on the receiving conveyor 5 in order to constitute the longitudinal stack 11.
  • the stack 11 then enters the compression device 6, the longitudinal faces 12 of the stack coming into contact with the films 7 stretched against the pressing surfaces of the belts 60.
  • the stack 11 is compressed, which generates the lateral overflow of the packaging films 7 against the lateral faces 13 of the stack.
  • the shapers 61 correctly fold the films which are then secured by the welding nozzles 62.
  • the compressed and packaged stack 11 At the outlet of the compression and packaging device 6 is cut transversely by means of the paper cutter 8 the compressed and packaged stack 11, the cutter being periodically operational as a function of the linear speed of displacement of the stack to obtain the length of the stack. adequate pens.
  • the invention therefore makes it possible, thanks to the bifurcation and convergence device, and means for guiding and depositing the strips to form the stack 11, to gather several strips in the form of a single treatment line and to operate the compression and packaging and cutting at once while the state of the art imposes a line of mineral strip treatment extracted from the original fiber mat.
