Description
Descrizione del Brevetto per Invenzione Industriale dal titolo: Description of the Patent for Industrial Invention entitled:
"IMPIANTO E METODO PER LA CURVATURA DI ARTICOLI DI LEGNO" "PLANT AND METHOD FOR BENDING WOODEN ARTICLES"
L'invenzione riguarda un metodo per la curvatura di articoli di legno, ed impianto perfezionato per l'attuazione di tale metodo, dotato di mezzi atti a conseguire un rilevante risparmio nel consumo di energia elettrica e di sicurezza operativa. The invention relates to a method for bending wooden articles, and an improved plant for carrying out this method, equipped with means suitable for achieving significant savings in the consumption of electrical energy and operational safety.
Ci sono vari metodi ed apparati per la formatura, ed in particolare la curvatura, di articoli di legno già noti e ampiamente utilizzati nella tecnica, e che per brevità non vengono ripetuti. There are various methods and apparatuses for forming, and in particular bending, wooden articles already known and widely used in the art, and which for the sake of brevity are not repeated.
Qualità Quality
Si impregna generalmente di umidità il legno , tuttavia, questa tecnologia necessita di impiego di riscaldamento, quindi di grande impiego di energia con risultati non sempre ottimali in quanto il legno riscaldandosi in modo irregolare non si piega uniformemente. The wood is generally impregnated with humidity, however, this technology requires the use of heating, therefore a large use of energy with not always optimal results as the wood heating irregularly does not bend uniformly.
* Consumo di energia * Energy consumption
Per alimentare elettricamente le sorgenti a R.F. che producono il riscaldamento degli articoli di legno, è necessario avere a disposizione notevole energia elettrica. E' evidente che tale elevato consumo, causa un costo economico molto rilevante, avendo i circuiti elettrici rendimento inferiore al 50% ed essendo l'energia elettrica notoriamente molto costosa. To electrically power the R.F. that produce the heating of the wooden articles, it is necessary to have a considerable amount of electricity available. It is evident that this high consumption causes a very significant economic cost, since the electrical circuits have an efficiency of less than 50% and electricity is notoriously very expensive.
Sicurezza Safety
Elevate potenze elettriche, possono creare piccole fughe di energia che inquinano l'ambiente, rischio che si vuole ridurre al minimo; contatto diretto da parte dell'operatore con parti roventi e quindi pericolose. High electrical powers can create small energy leaks that pollute the environment, a risk that must be reduced to a minimum; direct contact by the operator with hot and therefore dangerous parts.
DESCRIZIONE DESCRIPTION
Il campo specifico di utilizzo per questo tipo di piegatura del legno è la liuteria, e di quanti abbiano esigenza di piegare articoli di legno di ridotto spessore. The specific field of use for this type of wood bending is lutherie, and of those who need to bend wooden articles of reduced thickness.
Attualmente si utilizzano particolari resistenze elettriche o forme con elevate conducibilità termiche atte a disperdere calore, vedi fig. 1, di forma ellittica, portate a temperature quasi roventi, , a cui va a diretto contatto il legno da piegare. Currently, particular electrical resistances or forms with high thermal conductivities are used to disperse heat, see fig. 1, elliptical in shape, brought to almost scorching temperatures, to which the wood to be bent comes into direct contact.
Utilizzando questa tecnica, si possono creare frequenti rotture, scheggiature e bruciature delle parti lignee che deturpano, in modo significativo il lavoro eseguito; sono pure caratterizzate da un dispendio notevole di tempo e di energie e con relativa perdita di qualità del prodotto finito. Using this technique, it is possible to create frequent breaks, chipping and burning of the wooden parts that significantly disfigure the work performed; they are also characterized by a considerable waste of time and energy and with a relative loss of quality of the finished product.
Questo sistema risulta essere pericoloso per eventuali immissioni di radiazioni, possibili perdite di elettricità e di pericolo per l' utilizzatore in quanto a diretto contatto con la resistenza elettrica, e con un consumo notevole di corrente elettrica. This system is dangerous for possible radiation emissions, possible electricity losses and danger for the user as it is in direct contact with the electrical resistance, and with a considerable consumption of electric current.
E' desiderabile, ed è lo scopo della presente invenzione, realizzare un metodo per la piegatura di articoli di legno, ed un relativo apparato atto a eseguire detto metodo, e che sia in grado di eliminare, gli inconvenienti sopra descritti. It is desirable, and it is the object of the present invention, to provide a method for bending wooden articles, and a relative apparatus suitable for carrying out said method, and which is capable of eliminating the drawbacks described above.
L'impianto che si propone per la curvatura di legno di ridotto spessore anche stagionato comprende: uno stampo atto a creare la curvatura, e/o controstampi, mezzi idonei a piegare detti articoli di legno e di asciugarli rendendo stabile la curvatura. The system proposed for the bending of wood of reduced thickness, even seasoned, comprises: a mold suitable for creating the curvature, and / or counter-molds, means suitable for bending said wooden articles and drying them, making the curvature stable.
Tale scopo viene ottenuto con un particolare metodo di piegatura e di asciugatura di un articolo di legno, e di un relativo apparato, secondo le rivendicazioni allegate, e che sono espresse nella seguente descrizione fornita a scopo solo esemplificativo e non limitativo, con riferimento la figura 2 mostra in modo simbolico un disegno facilitato di uno stampo di tipo generale, e/o controstampo, di una prima forma atta alla realizzazione dell'invenzione. This object is achieved with a particular method of folding and drying a wooden article, and of a relative apparatus, according to the attached claims, and which are expressed in the following description provided for illustrative and non-limiting purposes only, with reference to the figure 2 shows in a symbolic way a simplified drawing of a general type mold, and / or counter-mold, of a first form suitable for the realization of the invention.
La fig. 3 mostra in modo semplificato lo schema funzionale dell'invenzione. Fig. 3 shows in a simplified way the functional scheme of the invention.
I vantaggi sono: The advantages are:
• grande qualità nella resa del prodotto finito, poiché si eliminano totalmente, scheggiature, bruciature e rotture delle parti lignee. Grande velocità esecutiva. • great quality in the yield of the finished product, since chipping, burning and breakage of the wooden parts are totally eliminated. Great executive speed.
• rilevante risparmio energetico, dato che per alimentare elettricamente le sorgenti a R.F. che producono il riscaldamento degli articoli di legno, è necessario avere a disposizione energia elettrica di potenza notevole fino a parecchi KW . E’ evidente che tale elevato consumo, causa un costo economico molto rilevante, avendo i circuiti elettrici ed elettronici rendimento inferiore al 50% ed essendo l’energia elettrica notoriamente molto costosa. • significant energy savings, given that to electrically power the R.F. which produce the heating of the wooden articles, it is necessary to have available electrical energy of considerable power up to several KW. It is evident that this high consumption causes a very significant economic cost, having the electrical and electronic circuits yield less than 50% and electricity being notoriously very expensive.
• Consistente riduzione di costi poiché si tratta di realizzare semplici stampi le cui caratteristiche sono mirate all’impiego specifico, ma i cui costi sono molto modesti; riscaldamento e asciugatura degli stampi in modo selettivo e soprattutto molto economico e veloce da eseguire. • Consistent cost reduction since it involves making simple molds whose characteristics are aimed at the specific use, but whose costs are very modest; heating and drying of the molds in a selective way and above all very economical and quick to perform.
• sicurezza totale poiché l’utilizzo di tecniche note e molto sicure, in quanto non viene emessa alcuna radiazione all’esterno, evitano inoltre il diretto contatto con parti roventi ed elettriche da parte dell’utilizzatore. • total safety since the use of known and very safe techniques, as no radiation is emitted to the outside, also avoids direct contact with hot and electrical parts by the user.
Per quanto riguarda il contesto industriale e tecnico, non sono note iniziative di alcun genere di Terzi relative o connesse al presente progetto. As regards the industrial and technical context, there are no known initiatives of any kind by third parties relating or connected to this project.
L’invenzione descritta consiste nell’immissione, riferimento (figura 2) nel foro C, di fluido, preferibilmente vapore acqueo, che riscalda in modo progressivo lo stampo A cavo, al quale viene appoggiato il listello di legno da piegare lungo tutto il perimetro E. The invention described consists in the introduction, reference (figure 2) into hole C, of fluid, preferably water vapor, which progressively heats the hollow mold A, on which the wooden strip to be bent is placed along the entire perimeter E .
Sovrapponendo lo stampo B allo stampo A, e inserendo tra i due il listello da piegare, si ottiene la curvatura desiderata. La realizzazione dello stampo B (figura 2), può essere vantaggiosamente eseguita con i fori C immissione e D aspirazione in modo da estendere al massimo i benefici e la controllabilità della presente invenzione. By superimposing the mold B on the mold A, and inserting the strip to be bent between the two, the desired curvature is obtained. The production of the mold B (figure 2) can be advantageously carried out with the intake holes C and D suction so as to maximize the benefits and controllability of the present invention.
Raffreddamento e stabilizzazione dell’articolo di legno mediante aspirazione forzata (figura 2) foro D, del rimanente fluido rimasto, ciò a tutto vantaggio dei tempi di esecuzione, e a beneficio dell’utilizzazione degli stampi, con notevole aumento dell’efficienza complessiva e ottimizzando la qualità del manufatto. Cooling and stabilization of the wooden article by forced suction (figure 2) hole D, of the remaining fluid left, this to the advantage of execution times, and to the benefit of the use of the molds, with a considerable increase in overall efficiency and optimizing the quality of the product.
