Definitions

  • the present invention relates to a heating plant for container preforms, utilised in particular before the blow moulding stage of containers made of plastic material. Background of the invention
  • Heating plants for container preforms made of plastic material are known to the prior art.
  • the heating of preforms generally takes place before the blow moulding or stretch-blow stage so as to bring the preform material to an appropriate temperature for obtaining a better quality moulded container.
  • the thermal energy source for the heating of the preforms generally consists of infrared radiation (IR) lamps.
  • IR infrared radiation
  • a further disadvantage is represented in that often there is achieved a low penetration of heat in the preform thickness, which determines an overheating of the external surface of the preform with consequent crystallisation of the PET, which compromises the subsequent blowing.
  • the main aim of the present invention is that of creating a preform heating plant which allows the optimisation of the focusing of the infrared radiation towards the preform, thus reducing the energy costs while maintaining an extremely high production rate.
  • a further aim of the invention is that of providing a preform heating plant that allows the optimisation of the penetration of heat throughout the preform thickness so as to make the temperature along said thickness as uniform as possible.
  • the present invention therefore proposes to achieve the above discussed aims by creating a heating plant for container preforms which, according to claim 1 , comprises at least one heating module configured so as to define at least one tunnel, laterally arranged with respect to a longitudinal plane X, for the passage of the preforms to be heated, said at least one heating module comprising one first portion provided with forced ventilation means, at least one first lateral portion, arranged at a first side of said first portion, provided with a plurality of infrared radiation lamps for heating the preforms, wherein said first portion and said at least one first lateral portion are configured so as to define at least one tunnel part, delimited on a first side of said infrared radiation lamps; on a second side, opposite to the first side, by at least one plate; on a third side, transversal to said first and second side, by at least a second plate; said tunnel part being open at a fourth side, opposite to the third side, to allow preforms to pass; wherein the at least one first plate closes the lateral ends
  • the heating plant of the invention arranged upstream of the blow moulding plant, allows operation at a production rate of even 80.000 containers/hour, the energy saving is considerable.
  • a further advantage is represented in that the preform heating plant, object of the present invention, is provided with a channelling system for the air flows within IR whereby there is obtained a uniform distribution of air to the compartments of the furnace thus taking advantage of the structure's symmetries.
  • Figure 1 shows a perspective view of a heating plant according to the invention
  • Figure 2 shows a schematic, cross-sectional view of the heating plant according to the invention
  • Figure 3 shows a magnification of part of the view of Figure 2;
  • Figure 4 shows an exploded view of a first part of the plant of Figure 1 ;
  • Figure 5 shows a side view of a component of the plant of the invention
  • Figure 6 shows an perspective view of a second part of the plant of Figure ;
  • Figure 7 shows a magnification of part of the view of Figure 6.
  • FIG. 1 there is represented an embodiment of a heating plant for container preforms, globally indicated with the numerical reference 1 ( Figure 1 ).
  • the preforms to be heated are generally made of plastic material, for example PET, PP, PLA, PVC, but the plant of the invention can also be utilised to heat moulded preforms or containers made of other plastic material, or of a combination of some of these materials.
  • the heating plant 1 is substantially symmetrical with respect to the longitudinal plane X, and comprises one or more modules 1 ', arranged sequentially one to the other.
  • the heating plant comprises just one symmetrical module or one or more modules having asymmetrical shapes, i.e. with heating only applied by one side or combinations of asymmetrical modules with symmetrical modules.
  • the heating plant comprises just one symmetrical module or one or more modules having asymmetrical shapes, i.e. with heating only applied by one side or combinations of asymmetrical modules with symmetrical modules.
  • the modules V are configured so as to define two tunnels 2, 2', symmetrically arranged with respect to plane X for the passage of the preforms 40 to be heated, which are transported by a transfer chain equipped with backing pads (not illustrated).
  • the passage of the preforms 40 from the tunnel 2 to tunnel 2', or vice versa, takes place by means of curved stretch 31 , connecting the ends of said tunnels, through which the transfer chain passes.
  • Some collectors 30 are advantageously envisaged for the heating liquid to keep at a lower temperature the preform neck area, which must not be heated by the furnace in the course of the heating process to which the preforms are subjected.
  • Each module V comprises a central portion 16 and two lateral portions 17.
  • At least one air suction filter 3 arranged on the lower wall of the central portion 16, said air originating from the environment external to the plant, at room temperature:
  • At least one ventilator 4 attached to the upper wall of the central portion 16 and provided with a impeller 5, placed in the hollow part 18 of the central portion 16 and substantially at the centre of the module V between the respective portions of tunnel 2, 2' of the module itself;
  • Each lateral portion 17 comprises at least one IR lamp 6 set for each length stretch of tunnel 2, 2' and a relative lamp support structure, in the form of p plates 25.
  • Each length stretch of tunnel 2, 2' is delimited on a first side by said at least one IR lamp 6 set; on a second side, opposite to the first side, by said first metal plate 7, preferably made of aluminium; on a third side, transversal to said first and second side, by a second metal plate or sheet 8, preferably made of aluminium.
  • a fourth side of the tunnel, opposite to the third side, is on the other hand open to allow the passage of the preforms 40 by means of the transfer chain.
  • Each IR lamp set 6, supported by a support structure 39 is positioned in a respective housing provided in the structure of the reflector 9, preferably made of aluminium. This reflector is provided with a number of housings 10, 10' at least equal to the number of lamps 6.
  • Each housing has a longitudinal extension or length suitable for fully housing each lamp 6 along its longitudinal extension or length.
  • At least one of the surface of the housings 10, 10', the surface of the first plate 7 and surface of the second plate 8, is completely coated in gold to optimise the reflection of the infrared radiation.
  • both the surface of the housings 10, 10' and the surface of the first plate 7 and the surface of the second plate 8 are completely coated in gold.
  • the layer of gold coating preferably having a thickness of between 0.01 pm e 0.1 ⁇ , and even more preferably equal to 0.05pm, can be created by spraying or by applying a film or by electroplating.
  • Each housing 10, 10' has a surface consisting, in part, of a lateral, semi-cylindrical surface 12 and in part of flat surfaces 11 , which extend said lateral surface 12 at each end.
  • said flat surfaces 11 allow the lamps 6 to be entirely or almost entirely housed in each housing, allowing that part of infrared radiation that is generally dispersed to be recovered, while being optimally focused towards the area of passage of the preforms 40.
  • each housing 10 is configured so that the radius R of the lateral, semi-cylindrical surface 2 is of between 6 and 8 mm and the width L of said flat surfaces 1 is of between 2 and 3 mm whereby, one the lamp 6 has been placed in the housing, the front ends 13 of the flat surfaces 1 are positioned so as to cover at least the longitudinal, vertical centre-line of the lamp 6 by at least 1 mm.
  • the IR lamps 6 are entirely arranged within the corresponding housing.
  • the distance between centres D of one housing and the next is advantageously of between 14 and 24 mm.
  • the IR lamps 6 preferably used are of the short wave type with temperature of 2400 K.
  • quartz lamps at a temperature of 1800 K, of the low thermal inertia type, known as medium wave IR lamps can be used, or NIR lamps, with temperatures of up to 3400°K.
  • the IR lamps 6 preferably have a diameter of 10 ⁇ 12 mm, even more preferably of 11 mm.
  • the reflector 9 cooperates at the level of the two lateral ends 29 with respective perforated plates 25, wherein perforations 26 are envisaged at the level of the housings 0 for insertion of the ends of the IR lamps 6.
  • perforations 26 are envisaged at the level of the housings 0 for insertion of the ends of the IR lamps 6.
  • a further advantage is represented in that at least the lower housing 10' of the reflector 9 is arranged staggered with respect to the other housings 10 of the same structure.
  • the lower housing 10' is positioned further forwards, i.e. more internally in the respective length stretch of tunnel and therefore closer to the advancement direction of the preforms 40, with respect to the other housings 10, by a distance equal to around 4 ⁇ 6 mm.
  • This entails that the flat, lower surface 11' of the housing 10, adjacent to the lower housing 10', has a length L' of between 6 and 10 mm, greater than the length L of all the other flat- surfaces 11.
  • the plate 8 has a broken line profile and is attached to one end of the upper wall of the central portion 16 of the module 1 ' by means of appropriate fastening means.
  • the profile of the plate 8 is configured so that IR minimises infrared radiation losses, and therefore heat losses, within each length stretch of tunnel.
  • each second plate 8 can be attached to a first end of the upper wall of the central portion 16 and to a second end of the upper wall of a lateral portion 17 of the module 1 '.
