Purtroppo, i noti impianti di verniciatura a spruzzo presentano una produttività limitata, in caso di verniciatura di pezzi molto sagomati sì presenta una notevole quantità di over-spray che si deposita sul nastro trasportatore e infine, si manifestano difficoltà nella perfetta verniciatura dei bordi del pezzo in movimento. Unfortunately, the known spray painting systems have a limited productivity, in the case of painting very shaped pieces there is a considerable amount of over-spray which is deposited on the conveyor belt and finally, difficulties arise in the perfect painting of the edges of the moving piece.

Scopo della presente invenzione à ̈ di ovviare agli inconvenienti appartenenti allo stato anteriore della tecnica e di proporre un impianto di verniciatura con rendimento maggiore, con il quale sia possibile verniciare perfetamente anche pezzi sagomati, pezzi stretti e lunghi, nonché pezzi disposti in posizione a libera scelta sul nastro trasportatore. Tale scopo viene raggiunto, secondo la presente invenzione, con un impianto di verniciatura di pannelli e profilati, destinati all’industria del mobile, comprendente un nastro per il trasporto dei pezzi, che parallelamente al nastro di trasporto si estendono al disopra del nastro delle guide parallele, le quali accolgono una traversa, movibile in modo comandato lungo le guide parallele, che la traversa presenta su ambedue i lati delle guide trasversali e che ogni guida accoglie una testa di verniciatura movibile in modo comandato lungo le guide trasversali che inoltre, le teste di verniciatura sono movibili in modo comandato in un piano verticale e che infine le teste di verniciatura possono essere mosse in modo comandato intorno ad assi orizzontali e che per la lettura della posizione del pezzo sul nastro, all'inizio dei nastro trasportatore si prevede al disopra del nastro una barra di misurazione che emette segnali di comando in funzione della posizione del pezzo rispetto al nastro. The purpose of the present invention is to obviate the drawbacks belonging to the prior state of the art and to propose a painting system with higher efficiency, with which it is also possible to perfectly paint shaped pieces, narrow and long pieces, as well as pieces arranged in a free choice on the conveyor belt. This object is achieved, according to the present invention, with a painting system for panels and profiles, intended for the furniture industry, comprising a belt for transporting the pieces, which, parallel to the transport belt, extend above the belt of the parallel guides, which receive a crossbar, which can be moved in a commanded way along the parallel guides, which the crosspiece has on both sides of the transversal guides and which each guide houses a painting head which can be moved in a controlled way along the transversal guides which, moreover, painting heads can be moved in a controlled way in a vertical plane and that finally the painting heads can be moved in a controlled way around horizontal axes and that for reading the position of the piece on the belt, at the beginning of the conveyor belt it is foreseen to above the tape a measuring bar that emits command signals according to the position of the piece with respect to the tape or.

Come si può rilevare dalla figura 1 , l'impianto di verniciatura sotto forma di una cabina 1 , accoglie all’interno due guide parallele 2 e 3 e, su queste guide parallele può traslare in modo comandato (f) una traversa 4 che presenta guide trasversali 5 e 6. figure 2 shows the painting system in side view; and figure 3 shows the painting plant in front view. As can be seen from figure 1, the painting plant in the form of a booth 1, accommodates two parallel guides 2 and 3 inside and, on these parallel guides, a crosspiece 4 can move in a controlled manner (f) transverse guides 5 and 6.

Ogni guida 5, 6 accoglie una testa di verniciatura, indicata complessivamente con 7 e 8. Each guide 5, 6 accommodates a painting head, indicated as a whole with 7 and 8.

Le teste di verniciatura 7 e 8 saranno descritte più dettagliatamente di seguito. Paint heads 7 and 8 will be described in more detail below.

Dalla figura 1 si può rilevare che le teste di verniciatura 7 e 8 sono movibili in modo comandato lungo le guide 5 e 6 trasversali, come indicato mediante le doppie frecce (g). From figure 1 it can be seen that the painting heads 7 and 8 can be moved in a controlled manner along the transversal guides 5 and 6, as indicated by the double arrows (g).

All'inizio di un nastro trasportatore 9 che attraversa la cabina 1 e che accoglie i pezzi P, Ã ̈ prevista una barra 10 trasversale, realizzata vantaggiosamente come barra a fotodiodi che legge sia la posizione che la larghezza e la lunghezza dei pezzi P alimentati. At the beginning of a conveyor belt 9 which crosses the booth 1 and which receives the pieces P, a transversal bar 10 is provided, advantageously realized as a photodiode bar which reads both the position and the width and length of the fed pieces P.

Dalla figura 2, l'impianto di verniciatura 1 Ã ̈ rilevabile con le sue parti essenziali in vista laterale. From figure 2, the painting plant 1 can be seen with its essential parts in side view.

Chiaramente, si notano i pezzi P, ia cui posizione sul nastro 9 viene rilevata con l’ausilio della barra di misurazione 10 a fotodiodi. Clearly, the pieces P are noted, the position of which on the belt 9 is detected with the aid of the photodiode measuring bar 10.

Vantaggiosamente, per non sporcare il nastro di trasporto 9 con la vernice in eccesso, questo nastro 9 viene coperto in modo noto da uno strato di carta 11, carta avvolta, rispettivamente svolta da apposite bobine. Advantageously, in order not to dirty the transport belt 9 with the excess paint, this belt 9 is covered in a known way by a layer of paper 11, wound paper, respectively unwound from suitable reels.

Dalla figura 2 si può rilevare la traversa 4 movibile ad andirivieni e in modo comandato nel senso indicato dalla doppia freccia (f). Inoltre, si possono rilevare le guide trasversali 5 e 6 che accolgono le teste di verniciatura 7 e 8, previste sui lati opposti della traversa 4. From figure 2 it is possible to see the crossbar 4 which can be moved to and fro and in a controlled manner in the direction indicated by the double arrow (f). Furthermore, it is possible to detect the transversal guides 5 and 6 which receive the painting heads 7 and 8, provided on the opposite sides of the crosspiece 4.

Dalla figura 2 si può anche rilevare che le teste di verniciatura 7 e 8 possono essere mosse in modo comandato in un piano verticale come indicato con le doppie frecce (i). From figure 2 it can also be seen that the painting heads 7 and 8 can be moved in a controlled manner in a vertical plane as indicated by the double arrows (i).

Dalla figura 3 risulta che rimpianto di verniciatura, indicato complessivamente con 1, presenta una traversa 4 che accoglie le teste di verniciatura 7 e 8 movibili in modo comandato in piani verticali, come indicato mediante le doppie frecce (i), con particolare vantaggio, gli ugelli delle teste di verniciatura 7 e 8 possono essere anche mossi intorno ad assi orizzontali come indicato in figura 3 con l'ausilio delle doppie frecce {£). From figure 3 it appears that the painting unit, indicated as a whole with 1, has a crosspiece 4 which houses the painting heads 7 and 8 which can be moved in a controlled manner in vertical planes, as indicated by the double arrows (i), with particular advantage, the nozzles of the painting heads 7 and 8 can also be moved around horizontal axes as indicated in Figure 3 with the aid of the double arrows {£).

Grazie alla possibilità di muovere in modo comandato la traversa 4 come indicato con la freccia (f), grazie alia possibilità di muovere le teste di spruzzatura 7 e 8 in modo comandato in senso trasversale, come indicato dalle frecce (g), grazie alla possibilità di muovere le teste di verniciatura 7 e 8 in modo comandato in un piano verticale come indicato mediante le doppie frecce (i) e grazie alla possibilità di eseguire con gli ugelli di spruzzatura delle teste 7 e 8 anche un movimento di oscillazione, come indicato in figura 3 con l’ausilio delle frecce (£), diventa possibile adattarsi in modo perfetto alla situazione di verniciatura, nel senso che le teste di verniciatura 7 e 8 vengono mosse e posizionate a seconda della posizione dei pezzi P, assunta sul nastro trasportatore 9. Considerando che i movimenti f, g, i, £ dovranno essere eseguiti con massima precisione e in funzione della posizione dei pezzi P sul nastro 9, si prevede la barra 10 di lettura, che trasmette i dati rilevati ai pezzi trasportati sul nastro 9 al sistema a controllo numerico della macchina, per muovere nella posizione desiderata, ad esempio con l’ausilio di motori comandabili che azionano viti di precisione, le teste di verniciatura 7, 8 rispetto al pezzo P in movimento. Thanks to the possibility of moving the crosspiece 4 in a controlled manner as indicated by the arrow (f), thanks to the possibility of moving the spraying heads 7 and 8 in a controlled manner in a transverse direction, as indicated by the arrows (g), thanks to the possibility of to move the painting heads 7 and 8 in a controlled manner in a vertical plane as indicated by the double arrows (i) and thanks to the possibility of performing an oscillation movement with the spray nozzles of the heads 7 and 8, as indicated in figure 3 with the help of the arrows (£), it becomes possible to adapt perfectly to the painting situation, in the sense that the painting heads 7 and 8 are moved and positioned according to the position of the pieces P, assumed on the conveyor belt 9. Considering that the movements f, g, i, £ must be performed with maximum precision and according to the position of the pieces P on the belt 9, the reading bar 10 is provided, which transmits the data detected to the pieces conveyed on the belt 9 to the numerical control system of the machine, to move the painting heads 7, 8 to the desired position, for example with the aid of controllable motors that drive precision screws .
