“PROCEDIMENTO PER LA CURVATURA DI UN PANNELLO DI RESINA†. â € œPROCESS FOR THE BENDING OF A RESIN PANELâ €.
TESTO DELLA DESCRIZIONE TEXT OF THE DESCRIPTION
La presente domanda di brevetto per invenzione industriale ha per oggetto un procedimento per la curvatura di un pannello di resina piano dopo che lo stesso à ̈ stato sottoposto ad una o più lavorazioni di finitura. The present patent application for industrial invention relates to a process for bending a flat resin panel after it has been subjected to one or more finishing processes.
Attualmente per ottenere un pannello curvo in resina si ricorre ad un comune stampo di formatura, in cui viene iniettata la resina e dal quale viene sformato un pannello grezzo dal profilo curvo desiderato. Currently, to obtain a curved resin panel, a common mold is used, in which the resin is injected and from which a raw panel with the desired curved profile is demoulded.
Successivamente il pannello grezzo subisce vari processi di rifinitura, quali ad esempio squadratura, calibratura verniciatura, levigatura e spatolatura o brillantatura. Subsequently, the raw panel undergoes various finishing processes, such as squaring, calibration, painting, sanding and trowelling or polishing.
Tali processi di rifinitura risultano essere molto laboriosi e complessi, perché devono essere eseguiti, con tecnica artigianale, su un pannello curvo. These finishing processes turn out to be very laborious and complex, because they must be carried out, with an artisan technique, on a curved panel.
Va detto inoltre che risulta impossibile effettuare tali processi contemporaneamente su più pannelli utilizzando macchinari che lavorano in continuo, così come normalmente accade nella lavorazione di pannelli grezzi, a sviluppo piano. It should also be said that it is impossible to carry out these processes simultaneously on several panels using machines that work continuously, as is normally the case in the processing of rough, flat panels.
Ciò significa che detti processi di rifinitura devono essere effettuati su un singolo pannello curvo alla volta, con evidente n grande spreco di tempo ed elevati costi di manodopera. This means that said finishing processes have to be carried out on a single curved panel at a time, with evident n great waste of time and high labor costs.
Nel caso, poi, che si voglia realizzare un pannello curvo stampato in resina dalle facce decorate con cornici, bugne o disegni incisi, allora dette incisioni devono essere eseguite manualmente o comunque con l’impiego di sofisticate e costose macchine fresatrici, non potendo utilizzare su un pannello curvo le più semplici e comuni macchine a controllo numerico normalmente adottate per lavorazioni di pantografatura di pannelli piani . If, then, you want to make a curved resin molded panel with faces decorated with frames, bosses or engraved designs, then these incisions must be made manually or in any case with the use of sophisticated and expensive milling machines, not being able to use on a curved panel the simplest and most common numerical control machines normally used for pantographing of flat panels.
Scopo della presente invenzione à ̈ di eliminare gli inconvenienti della tecnica nota, fornendo un procedimento per la curvatura di un pannello piano di resina che sia pratico, versatile, efficiente, economico e di semplice realizzazione. The object of the present invention is to eliminate the drawbacks of the known art, providing a process for bending a flat resin panel that is practical, versatile, efficient, economical and easy to make.
Questi scopi sono raggiunti in accordo all’invenzione, con le caratteristiche elencate nell’annessa rivendicazione indipendente 1. These objects are achieved in accordance with the invention, with the characteristics listed in the attached independent claim 1.
Realizzazioni vantaggiose appaiono dalle rivendicazioni dipendenti. Advantageous embodiments appear from the dependent claims.
Il procedimento per la curvatura di un pannello di resina, secondo l’invenzione, comprende le seguenti fasi: The procedure for bending a resin panel, according to the invention, includes the following steps:
- stampaggio ad iniezione di resina in modo da ottenere un pannello piano, - resin injection molding in order to obtain a flat panel,
- lavorazioni di rifinitura del pannello piano di resina, in modo da ottenere un pannello piano rifinito, - finishing of the resin flat panel, in order to obtain a finished flat panel,
- riscaldamento del pannello piano rifinito finché il pannello raggiunge la temperatura di rinvenimento della resina, - curvatura del pannello piano rifinito e riscaldato, mediante uno stampo, in modo da ottenere un pannello di resina curvo. - heating of the finished flat panel until the panel reaches the tempering temperature of the resin, - bending of the finished flat panel and heated, by means of a mold, in order to obtain a curved resin panel.
Appaiono evidenti i vantaggi dell’invenzione, che consente di realizzare tutte le lavorazioni di rifinitura sul pannello piano e successivamente curvare il pannello piano rifinito senza danneggiare la superficie rifinita del pannello. The advantages of the invention appear evident, which allows to carry out all the finishing operations on the flat panel and then to bend the finished flat panel without damaging the finished surface of the panel.
Ulteriori caratteristiche dell’invenzione appariranno più chiare dalla descrizione dettagliata che segue, riferita a una sua forma di realizzazione puramente esemplificativa e quindi non limitativa, illustrata nei disegni annessi, in cui: Further characteristics of the invention will become clearer from the detailed description that follows, referring to a purely exemplary and therefore non-limiting embodiment thereof, illustrated in the attached drawings, in which:
la Fig. 1 à ̈ uno schema a blocchi illustrante schematicamente il procedimento per la curvatura di un pannello di resina secondo l’invenzione; Fig. 1 is a block diagram schematically illustrating the procedure for bending a resin panel according to the invention;
la Fig. 2 à ̈ una vista schematica in sezione illustrante la fase di riscaldamento e curvatura del pannello di resina secondo l’invenzione. Fig. 2 is a schematic sectional view illustrating the heating and bending phase of the resin panel according to the invention.
Con riferimento alla Fig. 1 il procedimento per la curvatura di un pannello di resina secondo l’invenzione prevede una prima fase di stampaggio (1) in cui viene realizzato un pannello piano (2). With reference to Fig. 1, the process for bending a resin panel according to the invention provides for a first molding step (1) in which a flat panel (2) is made.
La fase di stampaggio (1) prevede lo stampaggio ad iniezione di resine in uno stampo. Vantaggiosamente vengono utilizzate resine epossidiche, in particolare resine insature di poliestere. The molding phase (1) involves the injection molding of resins into a mold. Advantageously, epoxy resins are used, in particular unsaturated polyester resins.
Vantaggiosamente le resine sono caricate di pigmenti colorati, in modo da ottenere direttamente un pannello piano (2) del colore desiderato. Advantageously, the resins are loaded with colored pigments, so as to directly obtain a flat panel (2) of the desired color.
Il pannello (2) può comprendere un inserto (20) affogato in un mantello di resina (21) che circonda totalmente l’inserto. The panel (2) can comprise an insert (20) drowned in a resin mantle (21) that totally surrounds the insert.
Se la resina à ̈ colorata in modo non trasparente, l’inserto (20) non risulta visibile. If the resin is non-transparent colored, the insert (20) is not visible.
L’inserto (20) può avere funzione di riempimento ed alleggerimento del pannello, in questo caso l’inserto (20) à ̈ in un materiale più leggero rispetto al mantello (21) in resina di poliestere. Ad esempio l’inserto (20) può essere un foglio di PoliVinilCloruoro (PVC) o in poliuretano espanso. The insert (20) can have the function of filling and lightening the panel, in this case the insert (20) is made of a lighter material than the polyester resin shell (21). For example, the insert (20) can be a sheet of PolyVinyl Chloruoro (PVC) or polyurethane foam.
L’inserto (20) può anche avere funzione di irrigidimento del pannello, in questo caso l’inserto (20) à ̈ in un materiale più pesante rispetto al mantello (21). Ad esempio l’inserto (20) può essere un foglio di alluminio. The insert (20) can also have the function of stiffening the panel, in this case the insert (20) is made of a heavier material than the shell (21). For example the insert (20) can be aluminum foil.
In ogni caso, l’inserto (20) deve essere un foglio di materiale flessibile che può essere curvato assieme al pannello piano (2) di resina . In any case, the insert (20) must be a sheet of flexible material that can be bent together with the flat resin panel (2).
Il pannello piano (2) del colore desiderato viene sottoposto ad una serie di lavorazioni di rifinitura (3) che comprende ad esempio una o più delle seguenti lavorazioni nel rispetto o meno della sequenza sotto indicata : The flat panel (2) of the desired color is subjected to a series of finishing processes (3) which includes, for example, one or more of the following processes in compliance or not with the sequence indicated below:
- calibratura dello spessore del pannello (2); - panel thickness calibration (2);
- pantografatura del pannello (2) ; - pantographing of the panel (2);
- squadratura del pannello (2); - squaring of the panel (2);
- nuova calibrazione più fine dello spessore del pannello (2) ; - brillantatura del pannello (2) , fino a conferire alla sua superficie speculare e splendente - new finer calibration of the panel thickness (2); - polishing of the panel (2), until its surface is specular and shiny
Tutte queste lavorazioni di rifinitura possono essere effettuate, secondo tecnologie note, con l’ausilio di quegli stessi impianti, pure di tipo noto, con cui vengono lavorati in automatico ed in continuo i pannelli di legno piani All these finishing processes can be carried out, according to known technologies, with the aid of those same systems, also of a known type, with which the flat wooden panels are automatically and continuously processed.
Poiché gli impianti noti per le operazioni di rifinitura summenzionate sono ideatati per pannelli piani, tali operazioni di rifinitura risultano essere pratiche ed agevoli e si possono effettuare per più pannelli contemporaneamente o in continuo. Since the systems known for the aforementioned finishing operations are designed for flat panels, these finishing operations are practical and easy and can be carried out for several panels simultaneously or continuously.
Dalla fase di rifinitura (3) esce un pannello piano rifinito (4) che viene sottoposto ad una fase finale di riscaldamento e curvatura (5). From the finishing phase (3) comes a finished flat panel (4) which is subjected to a final phase of heating and bending (5).
Nella fase di riscaldamento il pannello piano rifinito (4) viene riscaldato fino alla temperatura di rinvenimento della resina. Per riscaldare il pannello rifinito (4) si può utilizzare sia un fluido caldo, allo stato gassoso o liquido, sia un stampo di curvatura opportunamente riscaldato Preferibilmente detta fase di riscaldamento avviene mediante acqua calda . During the heating phase, the finished flat panel (4) is heated up to the tempering temperature of the resin. To heat the finished panel (4) it is possible to use either a hot fluid, in a gaseous or liquid state, or a suitably heated bending mold. Preferably, this heating phase takes place by means of hot water.
Generalmente la temperatura di rinvenimento della resina à ̈ compresa tra 80 – 120 °C. Generally the tempering temperature of the resin is between 80 - 120 ° C.
Vantaggiosamente viene utilizzata una resina di poliestere che ha una temperatura di rinvenimento di circa 100 °C. In questo modo, come sorgente di calore si può utilizzare acqua calda ; il pannello (4) viene totalmente immerso in un bagno di acqua calda a 100 °C, dove viene lasciato fino a raggiungere la temperatura di rinvenimento della resina di stampaggio in modo uniforme; la scelta del bagno d’acqua assicura un veloce riscaldamento del pannello piano (4) , senza rischio di danneggiare la sua superficie rifinita . Advantageously, a polyester resin is used which has a tempering temperature of about 100 ° C. In this way, hot water can be used as a heat source; the panel (4) is totally immersed in a bath of hot water at 100 ° C, where it is left until it reaches the tempering temperature of the molding resin in a uniform manner; the choice of the water bath ensures rapid heating of the flat panel (4), without the risk of damaging its finished surface.
Una volta che il pannello (4) ha raggiunto la temperatura di rinvenimento della resina, esso viene curvato mediante un apposito stampo in modo da ottenere un pannello curvo (6). Once the panel (4) has reached the tempering temperature of the resin, it is curved by means of a special mold in order to obtain a curved panel (6).
Con riferimento a Fig. 2 viene descritta una forma preferita di realizzazione della fase di riscaldamento e curvatura (5). Una vasca (50) contiene acqua calda (51), a temperatura di 100°C,. Il pannello (4) viene immerso nell’acqua calda (51). With reference to Fig. 2, a preferred embodiment of the heating and bending step (5) is described. A tank (50) contains hot water (51), at a temperature of 100 ° C. The panel (4) is immersed in hot water (51).
Il pannello (4) à ̈ disposto secondo un piano sostanzialmente verticale ed à ̈ trattenuto ai suoi bordi superiore ed inferiore mediante opportuni trattenitori (52, 53). The panel (4) is arranged according to a substantially vertical plane and is held at its upper and lower edges by means of suitable retainers (52, 53).
Entro la vasca (50) Ã ̈ previsto uno stampo (7) che comprende una matrice (70) con una superficie convessa (71) ed un coperchio (72) con una superficie concava (73). Quando il pannello (4) raggiunge la temperatura di rinvenimento della resina, lo stampo (7) viene chiuso in modo che il pannello (4) sia compresso tra la matrice (70) ed il coperchio (72) , assumendo una conformazione curva come le superfici concava (71) e convessa (73) rispettivamente della matrice e del coperchio. Inside the tank (50) there is a mold (7) which comprises a matrix (70) with a convex surface (71) and a lid (72) with a concave surface (73). When the panel (4) reaches the tempering temperature of the resin, the mold (7) is closed so that the panel (4) is compressed between the matrix (70) and the lid (72), assuming a curved shape like the concave (71) and convex (73) surfaces of the matrix and lid, respectively.
In questo modo si ottiene un pannello curvo (6), dalla superficie rifinita e del colore desiderato. . In this way a curved panel (6) is obtained, with a finished surface and the desired color. .
Una volta ultimata la curvatura del pannello (6) , il suo raffreddamento avviene mediante acqua fredda che viene immessa nella vasca (50) dopo aver scaricato l’acqua calda (51). Once the bending of the panel (6) has been completed, it is cooled by means of cold water which is introduced into the tank (50) after having discharged the hot water (51).
Il pannello curvo (6) una volta estratto dallo stampo (7) mantiene perfettamente la sua forma curvata. The curved panel (6) once extracted from the mold (7) perfectly maintains its curved shape.
Generalmente la superficie esterna del pannello curvo (6) (cioà ̈ la superficie destinata ad restare a vista) à ̈ quella bombata. Per questo motivo, la superficie concava (73) del coperchio (72) vantaggiosamente può essere realizzata in vetro, per non danneggiare la superficie a vista del pannello. Generally the external surface of the curved panel (6) (that is the surface destined to remain visible) is the rounded one. For this reason, the concave surface (73) of the lid (72) can advantageously be made of glass, in order not to damage the visible surface of the panel.
Chiaramente anche la superficie convessa (71) della matrice può essere realizzata in vetro. Clearly, the convex surface (71) of the matrix can also be made of glass.
Anche se in fig. 2 per semplicità à ̈ stata illustrata una vasca (50) contenente un solo stampo (7) per la curvatura di un solo pannello alla volta, appare evidente che detta vasca potrà essere realizzata in dimensioni tali da poter ospitare più stampi (7), affiancati od impilati, in modo da curvare contemporaneamente più pannelli, abbattendo così i tempi e i costi del processo. Although in fig. 2 for simplicity, a tank (50) containing only one mold (7) has been shown for the curvature of only one panel at a time, it is clear that said tank can be made in such dimensions as to be able to accommodate several molds (7), side by side or stacked, in order to bend several panels at the same time, thus reducing the time and costs of the process.
Inoltre, anche se il pannello (4) à ̈ stato disposto in verticale e lo stampo (7) à ̈ stato illustrato con una matrice ed un coperchio, il pannello (4) può essere disposto in orizzontale su una matrice convessa, senza coperchio, operando la curvatura del pannello mediante applicazione di vuoto o aspirazione di aria. In altre parole la curvatura del pannello avviene mediante posizionamento del pannello sulla matrice ed aspirazione di aria o creazione di vuoto tra pannello e matrice, in modo che il pannello assuma il profilo convesso della matrice. Furthermore, even if the panel (4) has been arranged vertically and the mold (7) has been illustrated with a matrix and a lid, the panel (4) can be arranged horizontally on a convex matrix, without a lid, operating the curvature of the panel by applying vacuum or suction of air. In other words, the curvature of the panel occurs by positioning the panel on the matrix and aspiration of air or creation of vacuum between the panel and the matrix, so that the panel assumes the convex profile of the matrix.
Alle presenti forme di realizzazione dell’invenzione possono essere apportate numerose variazioni e modifiche di dettaglio, alla portata di un tecnico del ramo, rientranti comunque entro l’ambito dell’invenzione espresso dalle rivendicazioni annesse. Numerous variations and modifications of detail can be made to the present embodiments of the invention, within the reach of a person skilled in the art, however falling within the scope of the invention expressed by the appended claims.
