Definitions

  • the object of the present invention comprises a procedure for the controlled in situ transformation and application of fibres in civil and road constructions.
  • These fibres are manufactured in large fibre-producing plants which are remote from the construction sites and mixing stations, and from where they are served in bags, the form in which they arrive there. Once there, the mixture is made manually in the mixing station by one or more operators who constantly feed the station from the bags of manufactured fibres or by pouring them manually into dispensing devices.
  • the present invention as defined in claim 1 substantially improves the procedures for the incorporation of fibres in road and civil construction stations which are currently used.
  • said procedure enables the fibre to be manufactured on site, personalizing its properties according to the requirements at every moment such that it is possible to vary said properties at any time in an exceptionally simple way. Furthermore, it makes it possible to continuously feed the mixing station automatically without the intervention of any personnel, ensuring a perfectly homogeneous product at all times.
  • the novel procedure for the controlled transformation and application of fibres in civil and road constructions comprises three phases.
  • the first of these consists of unwinding the ball of raw fibre to produce a continuous strand or sheet of material of uniform tension.
  • the second phase consists of cutting the band of material into segments of a certain length depending on the properties of the material with which said segments are to be mixed.
  • the third phase consists of transportation to the mixing station and dispensing the product in the volume required.
  • a continuous band 1 unwound from a ball of raw material 2 enters a turret 3 by means of a foot with an input guide 4, said guide being provided with a plurality of rollers or pulleys, whose function is to neutralize the overpressures and distensions produced during the unwinding of the fibre, as well as a knot detector 13 which brings the entire process to a halt if any irregularity in the strand of material is located.
  • the second phase begins in which the band of material, now at a constant tension, enters a guide 5 which introduces the material into the cutting station which comprises a cylinder provided on its peripheral edge with a plurality of blades 6 and over which the band of material winds such that two effects are produced, the first of these being one of traction whilst the blades and fibres are in contact and as a result of which the entire strand of fibre advances and the ball of raw material is unwound, the second effect comprising the final cutting of the fibre into segments of a certain length. All of this is possible since the cutting action of the blades is progressive rather than an instantaneous sectioning.
  • the volume of fibre cut is determined by the speed with which the cutting cylinder rotates and the tension of the continuous strand of material, the weight of the strand being constant along its entire length, this length depending on the distance between the blades.
  • the last phase of the process is begun, wherein the fibre is conveyed to the construction sites own mixing station 7 by means of a tube 8 provided with flexible zones 9 for making bends and avoiding obstacles and through which the material runs, driven pneumatically by an impulsion gang 10.
  • the volume dispensed is determined by means of the cutting speed and the pneumatic pressure in the tube, said pressure always being in accordance with the volume of the product which is cut in the previous phase.
  • All of the mechanical elements are situated on a travelling platform 11 which is also provided with a control panel 12 for controlling the entire process.
  • Said panel may be provided on a transportable console in order that it may be transferred to a specific part of the site where the rest of the controls for other machines and processes are situated so that a single person can control them all simultaneously.

Claims (4)

  1. Une procédure pour la transformation et l'application contrôlées in situ de fibres dans les constructions civiles et de routes caractérisées par une bande continue (1) qui se déroule d'une pelote de matière première (2); cette bande entre dans un porte-outil (3) qui absorbe toutes surtensions et distensions au fur et à mesure du déroulement de la fibre et qui est pourvue d'un détecteur de noeuds (13) lequel provoque l'arrêt de tout le procès si une irrégularité quelconque dans le brin du matériau est repérée. La bande de matériel, maintenant à tension constante, entre ensuite dans une station de coupe (6) consistant en un cylindre pourvu d'une multitude de lames sur son bord périphérique et sur lequel la bande de matériel s'enroule de telle sorte que deux effets se produisent; le premier d'entre eux étant la traction par friction pendant que les lames et les fibres sont en contact et le deuxième comprenant la coupe finale de la fibre laquelle, une fois coupée en segments d'une longueur adéquate, est finalement convoyée jusqu'à la station de mélange (7) au moyen d'un tube articulé (8) au travers duquel le matériel est acheminé, entraíné pneumatiquement par une bande d'impulsion (10).
  2. Un procédé pour la transformation et l'application contrôlées de fibres in situ dans les constructions civiles et de routes conformément à la revendication précédente, caractérisé par le fait que la longueur des segments de fibre coupée est déterminée en fonction de la distance entre les lames situées sur le cylindre, le volume de production étant déterminé par la régulation de la vitesse de rotation de ce cylindre porte-lames et par la tension à laquelle le brin continu de fibre est fourni; ce brin a un poids constant tout au long de sa longueur totale.
  3. Une procédure pour la transformation et l'application contrôlées de fibres in situ dans les constructions civiles et de routes conformément aux revendications précédentes, caractérisée par le fait que la distribution des fibres versées dans la station de mélange est déterminée moyennant la vitesse de coupe et la pression pneumatique maintenue à l'intérieur du tube, cette pression étant conforme au volume du produit fourni par la station de coupe.
  4. Une procédure pour la transformation et l'application contrôlées de fibres in situ dans les constructions civiles et de routes conformément aux revendications précédentes, caractérisée par le fait que tous les éléments mécaniques sont situés sur une plate-forme mobile (11), laquelle est également pourvue d'un panneau de contrôle transportable (12) pour le contrôle de tout le procès.
