Definitions
- the present invention refers to an improved infrared heating oven for conditioning individual items moving substantially in a continuous manner and in an aligned arrangement inside said oven.
- the present invention applies preferentially to moulding machines capable of moulding at the same time a plurality of plastic items, which are generally known as "preforms" in the art and are intended for subsequent blow- moulding into appropriate final containers, especially plastic bottles.
- the machines used to mould the final products ie. to blow mould said preforms into said final containers, are usually defined as “single-stage machines", since they are capable of carrying out the whole process needed to convert the raw plastic material from the pelletized form in which it is fed to the machine, into the finished product, ie. said final containers.
- preforms are heated up to an optimum predefined temperature for blow moulding, and this is usually carried out in appropriate conditioning ovens that make use of infrared lamps as heating means.
- the neck portion of said preforms must anyway remain cold, ie. at a lower temperature than the glass transition temperature, so that the subsequent blow moulding operations will not cause it to distort.
- thermo stabilization /inversion it is a commonly felt r eed for the interior of the oven and the outer surface of the preforms arranged therein to be ventilated with a flow of air at a pre-established, a -way relatively low temperature, so that the material lying on the outer suri ' ace of the preforms is prevented from being brought up to an excessively high temperature that would cause it to crystallize, while waiting for the material lying inside the preforms to reach the required blow-moulding temperature.
- Such a ventilation enables the ambient temperature inside the oven to be kept at a desirable level, while eliminating any excessive heat due to infrared rays that fail to be captured, ie. retained by the preforms themselves, as well as the "skin" temperature of the preforms to be mitigated.
- Such a desirable level of the internal temperature of the oven is the one that actually enables the energy efficiency of the oven to be optimized. It is in fact a largely known point that it is a function of the thickness of the preforms.
- the ventilation of the oven must be carried out at an adequate flow rate in view of being able to satisfactorily perform such a function, and it is desirable that the ventilation itself is well distributed all over the interior of the oven in such a manner as to ensure that the whole surface of the wall of the preform, which must be heated up, is actually treated in an even, homogeneous manner.
- the bottom of the preform ie. the closed portion opposing the neck thereof, fails to be irradiated by the upper lamp to any adequate extent, so that it undergoes an uncertain, generally unsatisfactory' heating effect; if the number of these lamps is going to be increased in view of doing away with such a problem, this would on the other hand give rise to other problems, since the lamps themselves would in this case be exposed to a greater extent to the flow of cooling air and, therefore, would show different radiating characteristics;
- the present invention may take the form of a preferred, although not sole embodiment such as the one that is described in detail and illustrated below by way of non-limiting example with reference to single accompanying drawing, which is a vertical cross- sectional view of a portion of an oven according to the present invention, as illustrated in a symbolical manner.
- a heating and conditioning oven according to the present invention is essentially comprised of:
- conduit 1 into which the cooling air is blown and through which the preforms 5 are caused to move in a direction that is substantially transversal with respect to the flow 6 of said cooling air, said conduit being also provided with:
- blower 22 adapted to take in fresh air through said intake inlet and blow it into said conduit in the direction of said preforms and said front
- the front grid 8, the battery of lamps 4 and the reflective wall 7 are arranged each on a respective plane, and all these respective planes are substantially parallel to the plane on which said preforms are caused to move along inside said conduit and transversally with respect to the latter.
- the reflective wall 7 must furthermore be provided with a plurality of apertures 10, and the heating lamps 4 must be separated from each other by appropriate gaps or intervals 40, so that the passage of the cooling air therethrough is advantageously promoted. After so flowing over and touching said lamps 4, said air flow, as it moves further on towards the exhaust aperture 3, reaches said reflective wall 7 and, filtering through said apertures 10, moves beyond them and away towards the exhaust aperture 3.
- a first one of such improvements relates to the cooling of the neck portion of the preforms. Since, as this has already been mentioned earlier in this description, such a neck portion should not be heated up, in order to avert such a possibility it is appropriate for the preforms to therefore be arranged and oriented with the neck portion thereof facing downwards and, as a result, with the bottom portion of the body thereof facing of course upwards.
- baffle plate 13 is so sized and arranged as to be able to intercept and stop those radiations that are reflected by said grid 8 and are directed downwards, ie. towards the zone of the neck portions of the preforms.
- said conduit In all cases, being it desirable that the neck portion of the preforms be capable of remaining as cold as possible, it is advantageous for said conduit to be able to contain said preforms over its whole height, while means 15 are provided there so as to be adapted to divert a part 25 of the cooling air flow directly against and beyond said neck portions, wherein said air is by no way involved by the heating action of said lamps.
- the same flow of cooling air that hits the body of the preforms, and that therefore moves through the heating lamps, is capable of being used to cool down also the sockets (not shown) of said lamps, without any need therefore arising for a special, different air flow to be additionally provided to this purpose, as this on the contrary occurs in prior-art solutions.
- a further reflective wall 17 is arranged between the inner wall of the conduit facing said bottom portions of the preforms moving therethrough and the bottom portions themselves, wherein this further reflective wall 17 is adapted to reflect the infrared radiation issued by said lamps 4, so as to ensure that the radiation so reflected by said wall 17 is capable to hit said bottom portions 16 of the preforms moving therethrough.
- said conduit is provided, in correspondence of the attachment perimeter of said grid 8, with appropriate lock-in slits 18, so that said grid is easily interchangeable with other grids having different characteristics, but being similarly capable of engaging said lock-in slits 18.
- the preforms are continuously and regularly caused to rotate about their respective axis. This actually enable successive portions of the body thereof to be directly irradiated by the lamps, which heat them up, while other portions, opposite thereto, are cooled down, thereby enabling heat to propagate through and into the thickness of the wall of the preforms, so as to attain in a balanced and gradual manner a uniform temperature throughout the body of the preforms, including the bottom portion thereof, while never reaching up to excessive temperatures, thanks to the cooling action ensured by said continuous flow of air.
- a flow of cooling air can be defined to solely involve the neck portions of the preforms, without it being affected by the heating action of the lamps at all and, as a result, without it being in turn capable of heating up said neck portions;
- the flow of cooling air is orthogonal to the plane on which the preforms move along and this ensures a great extent of uniformity in the cooling effect; furthermore, also the plane of the lamps lies parallel to the plane of the preforms, and these two particular circumstances, when combined with each other, ensure a maximum extent of uniformity in conditioning the preforms;
