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. Ein Verfahren für die kontrollierte in situ Transformation und Anwendung von Fasern bei Zivil- und Strassenkonstruktionen, charakterisiert dadurch, dass ein kontinuierliches Band (1) welches von einer Rohmaterialrolle (2) abgewickelt wird, wobei sich das genannte Band in einen Turm (3) begibt, welcher die Überspannungen und die Ausdehnungen die während der Abwicklung erzeugt werden absorbiert und welcher mit einem Knotendetektor (13) versehen ist, welcher den ganzen Prozess zum Halten bringt, sollte irgendeine Unregelmässigkeit im Materialstrang aufkommen, wobei der Materialstrang, jetzt konstant gespannt, dann in die Schneidestation (6) geleitet wird, welche aus einem Zylinder mit einer Vielfalt von Klingen auf der peripherischen Kante versehen besteht, über welchen Zylinder das Materialband gewunden wird, wobei zwei sich zwei Effekte ergeben. Der erste ist Traktion durch Friktion währenddem die Klingen und Fasern Kontakt haben miteinander, und der zweite umfasst der Endschnitt der Faser, welche, nachdem sie in Segmente von passender Länge geschnitten wurde, endlich durch einen beweglichen Schlauch (8) in welchem sich die Faser befindet, von einer pneumatisch getriebener Impulsgruppe (10) zur Mischungsstation (7) transportiert wird.
  2. Ein Verfahren für die kontrollierte Transformation und Anwendung von Fasern in situ bei Zivil- und Strassenkonstruktion laut des vorhergehenden Anspruchs, charakterisiert dadurch, dass die Länge des Segments des Faserschnitts festgelegt ist als Funktion der Distanz zwischen den Klingen die sich am Zylinder befinden, wobei das Produktionsvolumen festgelegt wird, indem man die Geschwindigkeit der Rotation des genannten klingentragenden Zylinders und die Spannung bei welcher der kontinuierlieche Faserstrand geliefert wird, reguliert, und wobei der genannte Strang der ganzen Länge nach ein konstantes Gewicht hat.
  3. Ein Verfahren für die kontrollierte Transformation und Anwendung von Fasern in situ bei Zivil- und Strassenkonstruktion laut der vorhergehenden Ansprüche, charakterisiert dadurch, dass die Austeilung der Fasermenge in die Mischungsstation durch die Schneidegeschwindigkeit und den pneumatischen Druck der innerhalb des Schlauches aufrecht erhalten ist, festgelegt wird und dieser Druck mit dem Volumen des von der Schneidestation abgegebenen Produkts übereinstimmt.
  4. Ein Verfahren für die kontrollierte Transformation und Anwendung von Fasern in situ bei Zivil- und Strassenkonstruktion laut der vorhergehenden Ansprüche, charakterisiert dadurch, dass sich alle mechanische Elemente auf einer beweglichen Plattform (11) befinden, welche auch mit einer tragbaren Kontrolltafel (12) für die Kontrolle des ganzen Prozesses ausgestattet ist.
