DESCRIZIONE DI INVENZIONE INDUSTRIALE DESCRIPTION OF INDUSTRIAL INVENTION
Domanda di brevetto per invenzione industriale avente per titolo: Patent application for industrial invention entitled:
"LEVIGATRICE-SPAZZOLATRICE PER PROFILI IN LEGNO " "SANDING-BRUSHING MACHINE FOR WOODEN PROFILES"
La presente invenzione ha per oggetto una macchina levigatricespazzolatrice per profili in legno. The present invention relates to a polishing-brushing machine for wooden profiles.
E' noto che oggi nel mercato esistono varie tipologie di codesti macchinari che in modo differenziato ottengono comunque la levigatura e la spazzolatura dei profili di legno. It is known that today on the market there are various types of these machines which in any case obtain the polishing and brushing of the wooden profiles in a differentiated way.
Le soluzioni ad oggi adottate sono applicate ai macchinari a seconda delle necessità e comunque si compongono tutte di un tappeto di traino del pezzo in gomma con sviluppo su tutta la lunghezza della macchina e di vari gruppi applicati lateralmente o sopra al pezzo da lavorare. The solutions adopted to date are applied to the machinery according to the needs and in any case they all consist of a conveyor belt for the rubber piece with development over the entire length of the machine and various groups applied laterally or above the piece to be worked.
Si identificano questi gruppi come gruppi operatori e nel merito in nastri abrasivi con tampone o gruppi con spazzole del tipo scotch-brite o ancora gruppi con spazzole a tela frastagliata. These groups are identified as operating groups and on the merit in abrasive belts with pad or groups with brushes of the scotch-brite type or groups with jagged cloth brushes.
Tali gruppi sono regolati dall'operatore manualmente o attraverso sistema a controllo numerico di seguito CNC prima dell'inizio della fase di lavorazione, pertanto se i pezzi da lavorare sono di diverso spessore e larghezza l'operatore sarà costretto ad intervenire manualmente o a mezzo CNC alla regolazione dei vari gruppi . Si procede poi, al posizionamento del pezzo sul tappeto di traino e sì inizia la fase di lavorazione. Il pezzo trainato dal tappeto arriverà ai vari gruppi che lo lavoreranno come precedentemente impostato manualmente o CNC dall'operatore prima dell'inizio della fase di lavorazione. These groups are adjusted by the operator manually or through a numerical control system hereinafter CNC before the start of the processing phase, therefore if the pieces to be machined are of different thickness and width the operator will be forced to intervene manually or by CNC at the regulation of the various groups. Then we proceed to the positioning of the piece on the towing belt and the processing phase begins. The piece pulled by the carpet will arrive to the various groups that will work it as previously set manually or CNC by the operator before the start of the processing phase.
Un notevole inconveniente di queste macchine consiste che ogni qualvolta l'operatore inserisce sul tappeto di traino un pezzo da levigare diverso per spessore dovrà sempre procedere alla regolazione manuale o a controllo CNC delle regolazioni precedentemente impostate. A notable drawback of these machines is that whenever the operator inserts a piece to be sanded of different thickness on the conveyor belt, he must always proceed with manual or CNC-controlled adjustment of the previously set adjustments.
Inoltre, la levigatura del legno con nastri abrasivi è un sistema copiativo in quanto il tampone in fase di levigatura va a contatto con il legno pneumaticamente e asporta il materiale in base a quanto è stato regolato, ma non sempre riesce a raddrizzare il profilo di legno in modo lineare. Altro noto difetto di queste levigatrici a nastro consiste nella levigatura di profili verniciati ad acqua, ovvero nella fase di levigatura il nastro surriscalda la vernice ad acqua rendendola 'gommosa' , questa si attacca al nastro lasciando striature in lunghezza sul pezzo ed il nastro non è più utilizzabile. Furthermore, the sanding of wood with abrasive belts is a copying system as the pad in the sanding phase comes into contact with the wood pneumatically and removes the material according to what has been adjusted, but it does not always manage to straighten the wooden profile. in a linear way. Another known defect of these belt sanders consists in the sanding of water-painted profiles, i.e. in the sanding phase the belt overheats the water-based paint making it 'rubbery', this sticks to the belt leaving streaks in length on the piece and the belt is not more usable.
Le spazzole del tipo scotch-brite e frastagliate risolvono in parte la levigatura dei profili verniciati ad acqua ma essendo spazzole copiative non riescono ad asportare completamente le eventuali colature dì vernice. Per ovviare a molti di questi inconvenienti delle levigatrici ad oggi note è stata ideata una macchina levigatrice-spazzolatrice atta alla soluzione delle note problematiche precedentemente dette. The scotch-brite and jagged brushes partially solve the sanding of water-painted profiles but being copying brushes they are unable to completely remove any paint dripping. In order to obviate many of these drawbacks of the currently known sanding machines, a sanding-brushing machine has been devised which is suitable for solving the previously mentioned known problems.
Scopo della presente invenzione è quello di realizzare una macchina levigatrice-spazzolatrice per la levigatura-spazzolatura atta alla soluzione dei difetti noti precedentemente illustrati. The object of the present invention is to provide a sanding-brushing machine for sanding-brushing suitable for solving the previously illustrated known defects.
Secondo la presente invenzione viene realizzata una macchina levigatricespazzolatrice a stazioni di lavoro comprendenti un tappeto corto di traino per l'entrata del pezzo, una barra pressore superiore , una guida lato destro , una unità levigatrice che può lavorare sotto o lateralmente od eventualmente ambo i lati ed infine un tappeto corto di traino per Γ uscita del pezzo. According to the present invention, a polishing-brushing machine with work stations is realized comprising a short conveyor belt for the entry of the piece, an upper pressure bar, a guide on the right side, a polishing unit that can work under or laterally or possibly both sides. and finally a short conveyor belt for the output of the piece.
Le unità orizzontali sono composte da un motore elettrico montato su struttura fissa con possibilità di regolazione decimale per asportazione del materiale ma comunque in linea con il tappeto di traino. Sopra a tale motore, comandato da inverter è montato un platorello roto orbitale con disco abrasivo a strappo. Le unita verticali sono composte da un motore elettrico comandato da inverter con platorello roto orbitale con disco abrasivo a strappo e da un sistema di ricerca automatica della larghezza del singolo pezzo. Questo sistema di ricerca automatica consiste nella lettura del pezzo preferibilmente attraverso fibra ottica la quale mediante PLC posiziona sia la barra pressore superiore in base all'altezza del pezzo e da consenso ad un pistone pneumatico a far scorrere un carrello montato su guide del tipo THK. A codesto carrello viene fissato un motore che per mezzo di una guida a ruote folli va ad appoggiarsi sul pezzo con una regolazione di asportazione di materiale dal pezzo già predefinita. The horizontal units are made up of an electric motor mounted on a fixed structure with the possibility of decimal adjustment for material removal but in any case in line with the conveyor belt. Above this motor, controlled by an inverter, there is a roto orbital pad with a tear-off abrasive disc. The vertical units are composed of an electric motor controlled by an inverter with a roto orbital pad with a tear-off abrasive disc and an automatic search system for the width of the single piece. This automatic search system consists in reading the piece preferably through optical fiber which by means of PLC positions both the upper pressure bar according to the height of the piece and gives consent to a pneumatic piston to slide a carriage mounted on guides of the THK type. A motor is fixed to this carriage which, by means of a guide with idle wheels, rests on the piece with a pre-defined adjustment of material removal from the piece.
Si evince che una volta data l'impostazione predefinita la macchina grazie a questo sistema ricerca in automatico il pezzo da levigare e anche se verranno passati spessori o altezze diverse la macchina sarà comunque in grado da sola di leggere e di eseguire la levigatura senza alcuna regolazione antecedente da parte dell'operatore. It is clear that once the default setting is given, the machine automatically searches for the piece to be sanded thanks to this system and even if different thicknesses or heights are passed, the machine will still be able to read by itself and perform the smoothing without any adjustment. antecedent by the operator.
Inoltre essendoci più unità, si ha la possibilità di comporre la macchina in base alle varie esigenze anche a distanza di tempo, senza dover essere vincolati da una struttura fissa. Furthermore, since there are more units, it is possible to compose the machine according to the various needs even after some time, without having to be bound by a fixed structure.
La particolare soluzione con tipo di platorello roto orbitale è ideale per la spianatura del legno senza provocare graffiature sia in senso longitudinale che in senso trasversale, con il vantaggio che dopo aver applicato la prima mano di vernice il legno si presenta più liscio senza alzare il pelo. The particular solution with the type of roto orbital pad is ideal for leveling the wood without causing scratches both longitudinally and transversely, with the advantage that after applying the first coat of varnish the wood is smoother without raising the pile. .
In particolare, la presente invenzione si propone dì realizzare una soluzione ideale per il problema noto sopra descrìtto dei profili con vernici ad acqua.il platorello roto orbitale è ideale per la levigatura delle vernici ad acqua in quanto il disco abrasivo gira lentamente ma vibra fortemente con una grossa asportazione di materiale ma senza riscaldare la vernice. In particular, the present invention proposes to provide an ideal solution for the known problem described above of profiles with water-based paints. a large removal of material but without heating the paint.
L'invenzione di questa macchina levigatrice-spazzolatrice comporta anche The invention of this sanding-brushing machine also involves
