Definitions

  • This invention relates to a machine which has been especially designed for the manufacture of tubular bodies, specifically cylindrical bodies which can be used as containers for various types of products in granular, powder or paste form, and which can also be used as formwork members in the context of construction for the production of cylindrical columns.
  • the machine uses various continuous sheets or strips which combine raw materials or a base of plant and/or synthetic fibres combined with multiple polymers, grouping them into a single complex or strip which is helically round and heat welded to produce the intended cylindrical tubular body.
  • This invention also has the quality of incorporating means for heating the strips, which is required in order to bring about softening of the plastics material included in the strip and their consequent fusion or heat welding to form the intended tubular body.
  • the invention therefore relates Lo the quality of obtaining a drastic reduction in the size of the machine or plant, with the consequences deriving therefrom from the point of view of making use of the space in which the said machine is located.
  • the Applicant is the proprietor of the patent of invention applied for in Spain under number P8803814, which describes a process for the manufacture of tubular containers and items of flat geometry.
  • tubular containers includes any type of container as such obtained using this kind of material, such as the cylindrical tubular bodies used as formwork for producing columns, which are also cylindrical, or any other practical support in which a body having these characteristics is required.
  • the machine for the manufacture of tubular bodies provided by the invention has been specially designed to produce cylindrical tubular bodies using the process according to the said patent of invention, specifically using raw materials based on plant and/or synthetic fibres combined with multiple polymers, configured into a strip or complex which may also incorporate a sheet of aluminium within it.
  • the invention also provides for a plurality of heating units located in the immediate vicinity of a mandrel within the said tunnel, specifically one for each strip which has to be heated, in such a way that by keeping the strips at a suitable distance from each other by means of an appropriate guide, despite the fact that they are moving together onto the mandrel, sufficient space is left for positioning the heating units between the same in the vicinity of the mandrel.
  • the machine for the manufacture of tubular bodies to which the invention relates is constructed on the basis of a fixed cylindrical mandrel, that is one which is immobilised in both rotation and in the axial direction, of a diameter which is consistent with the diameter of the tubular body which has to be obtained, and which is hollow and provided with cooling means, the purpose of which will be described below.
  • Tension in the strips is produced by a drawing device, based on a flat part which acts over the entire periphery of the mandrel, with the bundle of strips matching the shape of the latter placed in between, causing the strips to be drawn along with simultaneously sljppage of the same over the mandrel, which as a result of the inclination of the said strips gives rise to helical rolling of the same on the mandrel with simultaneous longitudinal displacement of the tube produced along the same.
  • the mandrel is projectingly mounted on a supporting structure at its end corresponding to the entry of the strips, in such a way that the tubular body obtained leaves freely from the other extremity of the mandrel, where a cutting device subdivides it into sections of predetermined length.
  • each spool is mounted on its own axis, rotating independently of the others, in order to maintain its linear movement substantially uniform, and they may have different angular velocities according to the different diameters of the spools used, each spool also being assisted by an auxiliary spool which enables the feed to the machine to be replaced substantially rapidly when the first spool is used up.
  • Another object of the invention is to achieve better use of space in that a plurality of heating units, specifically one for each strip which has to be heated, in the immediate vicinity of the said mandrel, and in the form of a tunnel, in such a way that by keeping the strips at a proper distance from each other by means of a suitable guide for the same, despite the fact that they are moving together onto the mandrel, leave sufficient space in the vicinity of the same for the location of heating units between them with the result that there is a minimum, virtually negligible, occupation of space by the heating units and the mandrel can be located effectively adjacent to the unwinder.
  • Each of the aforesaid heating units may comprise a pipe for blowing high temperature pressurised air, in the form of a pipe which widens corresponding to the width of the strip and is located transversely with respect to the latter, in which case the pressurised air circuit may incorporate a coil housed within a heater in which heating of the air up to temperatures which can reach 300°C can be achieved in such a way that blowing the pressurised air onto the conLinuous strips causes instantaneous heating of the same to the working temperature considered appropriate.
  • the various strips (5) are suitably guided by means of rollers (8) or by any other means to a heating tunnel (9) which opens out in the vicinity of the mandrel (10).
  • Said heating tunnel (9) is provided with internal separators (11) which keep strips (5) suitably apart, being assisted by a hot air generator (12) which engages the said tunnel (9) laterally and obliquely and which with the aid of a fan (13) provides air to the initial part of tunnel (9) at a temperature of between 160°C and 200°C, in such a way that a temperature of between 140°C and 190°C is maintained at the outlet from tunnel (9) and is sufficient for the plastics material, specifically polyethylene, incorporated in strips (5) to be in a thermal condition in which it adheres to both the other sheet of polyethylene and to any other sheet in the complex.
  • a hot air generator (12) which engages the said tunnel (9) laterally and obliquely and which with the aid of a fan (13) provides air to the initial part of tunnel (9) at a temperature of between 160°C and 200°C, in such a way that a temperature of between 140°C and 190°C is maintained at the outlet from tunnel (9) and is sufficient for the
  • Mandrel (10) is coolcd, having for this purpose an inlet (17) and an outlet (18) for water in order to prevent the high temperature at which strips (5) reach said mandrel (10) from causing adhesion of the same to mandrel (10) and also a lubricating liquid facilitating surface slip of the strips (5) with respect to the repeatedly mentioned mandrel (10) is applied thereto in this initial part of the said mandrel (10), which lubricating liquid has an oily nature and can be applied dropwise or by any other type of impregnator.
  • the device for drawing strips (5) over mandrel (10) comprises, as already stated previously, a broad planar annular belt (14) surrounding the perimeter of mandrel (10) extending between two cylinders (19) having parallel axes mounted on both sides of mandrel (10).
  • These two parallel axis cylinders (19) may be driven independently and synchronously through corresponding motors housed in base (20) supporting the same, or the said drive may be applied to only one of the cylinders (19), moving the other cylinder synchronously with it through transmission provided by planar belt (14), and mechanical or hydraulic motors may be used in each case.
  • a stabiliser bar (21) which is preferably telescopic, that is of a length which can be adjusted by means of a screw/nut system, which also incorporates an activating wheel (22), is provided between the upper free extremities of the same, that is of cylinders (19), in such a way as not only to ensure stability of the axes of the cylinders (19) but also to adjust the tension in planar (14), that is the pressure of the same on mandrel (10).
  • pipes (43) for blowing pressurised hot air may be replaced by burners located directly adjacent to strips (35), as gas-fired burners or infrared heaters.
