- la figura 2 Ã ̈ un particolare della vasca di stampaggio dell'impianto di figura 1; - figure 2 is a detail of the molding tank of the plant of figure 1;
- la figura 3 Ã ̈ uno spaccato prospettico esemplificativo di un prodotto realizzato secondo tale procedimento. - figure 3 is an exemplary perspective section of a product made according to this procedure.
Con riferimento alle figure citate un procedimento per la realizzazione di oggetti con impiego di polveri industriali di scarto, Ã ̈ ad esempio realizzabile con un impianto indicato con 10 in figura 1. With reference to the aforementioned figures, a process for making objects with the use of industrial waste powders can, for example, be realized with a plant indicated with 10 in figure 1.
Il procedimento secondo il trovato si caratterizza per il fatto di comprendere le seguenti operazioni. The method according to the invention is characterized in that it comprises the following operations.
Una prima operazione prevede di miscelare polveri termoplastiche, tipo polveri di verniciatura e simili, con polveri o granulati di riempimento, quali polveri di graniglia, graniglia e simili e altre polveri industriali di scarto, in una miscela di polveri; in figura 1 sono esemplificati tre silos 11, 12 e 13, ad esempio un primo silos 11 per polveri termoplastiche, un secondo silos 12 per polveri di graniglia o graniglia vera e propria, e un terzo silos 13 per polveri metalliche, le polveri termoplastiche essendo sempre presenti nella miscela, mentre le altre due tipologie di polveri possono essere mescolate alla polvere termoplastica in alternativa una all'altra, oppure in combinazione, a seconda delle esigenze e dell'oggetto che si vuole ottenere. A first operation involves mixing thermoplastic powders, such as painting powders and the like, with filling powders or granules, such as grit powders, grit and the like and other industrial waste powders, in a powder mixture; Figure 1 illustrates three silos 11, 12 and 13, for example a first silos 11 for thermoplastic powders, a second silos 12 for grit or actual grit powders, and a third silos 13 for metal powders, the thermoplastic powders being always present in the mixture, while the other two types of powders can be mixed with the thermoplastic powder as an alternative to one another, or in combination, depending on the needs and the object to be obtained.
Al di sotto dei silos 11, 12 e 13 vi sono altrettanti corrispondenti dispositivi di vagliatura di tipo in sà ̈ noto, rispettivamente 14, 15 e 16. Below the silos 11, 12 and 13 there are as many corresponding screening devices of a per se known type, 14, 15 and 16 respectively.
I dispositivi di vagliatura 14, 15 e 16 accompagnano le polveri ad un miscelatore 17, al quale à ̈ associato un nastro trasportatore per l'immissione della miscela di polveri ad un estrusore 18. The screening devices 14, 15 and 16 accompany the powders to a mixer 17, to which a conveyor belt is associated for introducing the powder mixture to an extruder 18.
La miscela di polveri entra nell'estrusore a temperatura ambiente, e ne esce a circa 140°C, in forma fluida. The mixture of powders enters the extruder at room temperature, and leaves it at about 140 ° C, in fluid form.
La seconda operazione del procedimento secondo il trovato prevede infatti di estrudere tale miscela di polveri, innalzandone la temperatura per rendere detta miscela di polveri fluida e omogenea, in uno stampo 19 per la realizzazione di un oggetto 20. In fact, the second operation of the method according to the invention envisages extruding this powder mixture, raising its temperature to make said powder mixture fluid and homogeneous, in a mold 19 for making an object 20.
Alla miscela di polveri, all'ingresso nell'estrusore 18, à ̈ possibile, in una alternativa del procedimento, aggiungere una sostanza legante, che favorisca l'amalgama della miscela di polveri nonchà ̈ la compattezza e le caratteristiche meccaniche dell'oggetto da realizzare. To the mixture of powders, at the entrance into the extruder 18, it is possible, in an alternative to the procedure, to add a binding substance, which favors the amalgam of the powder mixture as well as the compactness and mechanical characteristics of the object to be made. .
Tale sostanza legante può essere, ad esempio, una resina espandente, da introdurre in una quantità che può oscillare tra lo 0,05% ed il 15% della massa della miscela di polveri, a seconda dell'oggetto che si vuole ottenere e delle peculiarità tecniche che si vuole che tale oggetto abbia. This binding substance can be, for example, an expanding resin, to be introduced in an amount that can fluctuate between 0.05% and 15% of the mass of the powder mixture, depending on the object to be obtained and the peculiarities. techniques that you want that object to have.
All'interno dello stampo 19 Ã ̈ disposto almeno un elemento di irrobustimento strutturale da incorporare in detto oggetto 20. Inside the mold 19 there is at least one structural strengthening element to be incorporated in said object 20.
Nell'esempio qui descritto a titolo meramente esplicativo e non limitativo del trovato, tale elemento di irrobustimento à ̈ dato da una rete 21, metallica o in materia plastica, o in altro materiale a seconda delle esigenze. In the example described here for purely explanatory and non-limiting purposes of the invention, this strengthening element is given by a mesh 21, metal or plastic material, or other material according to requirements.
Tale elemento di irrobustimento à ̈ da intendersi poter essere di forma e dimensioni qualsiasi a seconda della forma e delle dimensioni dell'oggetto 20 che si intende realizzare mediante il procedimento secondo il trovato. This strengthening element is understood to be capable of being of any shape and size according to the shape and size of the object 20 to be made by means of the method according to the invention.
Lo stampo 19 si compone di una vasca 22 in cui si riversa dall'estrusore 18 la miscela fluida, di mezzi di supporto per l'elemento di irrobustimento strutturale, associati a detta vasca 21, e di una pressa 23 per la chiusura della vasca 22. The mold 19 consists of a tank 22 into which the fluid mixture is poured from the extruder 18, of support means for the structural strengthening element, associated with said tank 21, and of a press 23 for closing the tank 22 .
I mezzi di supporto sono dati, ad esempio, da spallamenti di appoggio 24 definiti sulle sponde 25 della stessa vasca 22 dello stampo 19. The support means are given, for example, by supporting shoulders 24 defined on the sides 25 of the same tank 22 of the mold 19.
In alternativa, in assenza di mezzi di supporto, si cola nella vasca 22 un primo strato di fluido estruso dall'estrusore 17, si pone l'elemento di irrobustimento a galleggiare su tale primo strato di fluido, e poi si cola nella vasca un secondo strato di fluido ad incorporare l'elemento di irrobustimento nella massa di fluido estruso da stampare. Alternatively, in the absence of support means, a first layer of fluid extruded from the extruder 17 is poured into the tank 22, the strengthening element is placed to float on this first layer of fluid, and then a second layer is poured into the tank. fluid layer to incorporate the strengthening element into the mass of extruded fluid to be molded.
Dopo l'operazione di estrusione con inserimento dell'elemento di rinforzo, vi à ̈ una operazione di di stampaggio, in cui la vasca 22 viene traslata al di sotto della pressa 23 che porta il coperchio della vasca 22, da intendersi come un controstampo cooperante con la vasca 22 alla definizione della sagoma dell'oggetto da realizzare 20. After the extrusion operation with insertion of the reinforcing element, there is a molding operation, in which the tank 22 is translated under the press 23 which carries the lid of the tank 22, to be understood as a cooperating counter-mold with the tank 22 to define the shape of the object to be made 20.
La pressa 23 chiude lo stampo 19 con un controstampo 27 con cui comprime il fluido contenuto nella vasca 22 per un predefinito intervallo di tempo, che dipende dalla forma e dalle dimensioni dell'oggetto 20 da realizzare. The press 23 closes the mold 19 with a counter-mold 27 with which it compresses the fluid contained in the tank 22 for a predefined time interval, which depends on the shape and size of the object 20 to be made.
In seguito all'apertura dello stampo 19, la vasca 22 subisce una operazione di raffreddamento in vasca d'acqua 28. Following the opening of the mold 19, the tank 22 undergoes a cooling operation in the water tank 28.
A seguito del raffreddamento, l'oggetto 20 viene estratto dalla vasca 22. Following cooling, the object 20 is extracted from the tank 22.
A tale serie di operazioni può seguire una operazione di plastificazione dell'oggetto estratto dalla vasca 22. This series of operations can be followed by a plasticizing operation of the object extracted from the tank 22.
Ad esempio tale plastificazione à ̈ realizzata per immersione in vasca 29, operazione in sà ̈ nota. For example, this plasticization is carried out by immersion in tank 29, an operation known per se.
E' da intendersi che tale operazione di plastificazione dell'oggetto 20 Ã ̈ realizzabile anche con altri metodi analoghi, simili ed equivalenti. It is to be understood that this plasticizing operation of the object 20 can also be carried out with other analogous, similar and equivalent methods.
La miscela di polveri può comprendere tra il 40% ed il 60% di polvere termoplastica, e la restante percentuale di polveri di graniglia, o di graniglia, o di polveri metalliche, o di polveri lignee, o di polveri di roccia, o di polveri di altri materiali simili, o di una mescola di una o più di tali polveri. The powder mixture can include between 40% and 60% of thermoplastic powder, and the remaining percentage of grit or grit powders, or metal powders, or wood powders, or rock powders, or powders. of other similar materials, or of a mixture of one or more of these powders.
La polvere termoplastica à ̈ da intendersi poter essere in generale una polvere di materia plastica che rammollisce alle alte temperature e solidifica a raffreddamento, quali sono ad esempio polveri epossidiche, fenoliche, acriliche, una polvere di verniciatura, e altre polveri simili. Thermoplastic powder is intended to be generally a plastic material powder that softens at high temperatures and solidifies upon cooling, such as, for example, epoxy, phenolic, acrylic powders, a painting powder, and other similar powders.
Le citate polveri e graniglia di riempimento sono da intendersi essere polveri di materiale pietroso, tipo di sassi, e/o di materiale metallico. The aforementioned filling powders and grit are intended to be powders of stony material, type of stones, and / or metallic material.
L'oggetto 20, qui rappresentato esemplificativamente come un parallelepipedo, à ̈ da intendersi avere la forma qualsivoglia a seconda delle necessità ed esigenze. The object 20, here represented by way of example as a parallelepiped, is intended to have any shape according to the needs and requirements.
Ad esempio, l'oggetto realizzato può essere una fioriera, realizzata impiegando una miscela contenente 55% di polvere di verniciatura e 45% di graniglia. For example, the object made can be a planter, made using a mixture containing 55% of painting powder and 45% of grit.
Si à ̈ in pratica constatato come il trovato raggiunga il compito e gli scopi preposti. In practice it has been found that the invention achieves the intended aim and objects.
In particolare, con il trovato si à ̈ messo a punto un procedimento per la realizzazione di oggetti che impiega vantaggiosamente polveri industriali di scarto, quali ad esempio le polveri di verniciatura, graniglia, polveri metalliche e altre polveri di scarto simili. In particular, the invention provides a method for manufacturing objects which advantageously uses industrial waste powders, such as for example painting powders, grit, metal powders and other similar waste powders.
Inoltre, con il trovato si à ̈ messo a punto un procedimento che consente la produzione di oggetti strutturalmente robusti e delle forme più varie, tipo cornici, telai per porte e finestre, vasi, fioriere, lastre per coperture, tegole e simili. Infatti la presenza dell'elemento di irrobustimento fa si che l'oggetto uscente dallo stampo, anche qualora presenti una certa fragilità in caso di urti di una certa intensità , si mantenga comunque compatto senza sbriciolarsi. Furthermore, the invention has perfected a process which allows the production of structurally robust objects of the most varied shapes, such as frames, frames for doors and windows, vases, flower boxes, roofing sheets, tiles and the like. In fact, the presence of the strengthening element means that the object coming out of the mold, even if it presents a certain fragility in case of impact of a certain intensity, remains compact without crumbling.
A tale compattezza contribuisce l'operazione di plastificazione che in caso di urto riduce il rischio di formazione di scheggiature che possano innescare inviti a rottura, e comunque coopera al trattenimento delle eventuali porzioni crepate e predisposte al distacco dal corpo principale dell'oggetto stesso. The plastification operation contributes to this compactness, which in the event of a collision reduces the risk of the formation of chips that can trigger breakage, and in any case cooperates in retaining any cracked portions that are predisposed to detachment from the main body of the object itself.
Infine, con il trovato si à ̈ messo a punto un procedimento allestibile con impianti, macchine e attrezzature di tipo noto e di costo contenuto. Finally, the invention has developed a process that can be set up with plants, machines and equipment of a known type and of low cost.
Il trovato, così concepito, à ̈ suscettibile di numerose modifiche e varianti, tutte rientranti nell'ambito del concetto inventivo; inoltre, tutti i dettagli potranno essere sostituiti da altri elementi tecnicamente equivalenti. The invention thus conceived is susceptible of numerous modifications and variations, all of which are within the scope of the inventive concept; moreover, all the details can be replaced by other technically equivalent elements.
In pratica, i materiali impiegati, nonché le dimensioni e le forme contingenti, potranno essere qualsiasi a seconda delle esigenze e dello stato della tecnica. In practice, the materials used, as well as the contingent shapes and dimensions, may be any according to requirements and to the state of the art.
