Description

TITOLO: Bordatura di pannelli utilizzati nell 'industria del mobile senza linea di giunzione visibile TITLE: Edging of panels used in the furniture industry without visible junction line

DESCRIZIONE (1/3) DESCRIPTION (1/3)

Campo della tecnica cui l'invenzione fa riferimento. Field of the art to which the invention refers.

Bordatura di pannelli di derivazione lignea utilizzati nell’industria del mobile (pannelli di particelle, di fibra, tamburati, compositi, in legno massiccio, lamellari, li steli ari, ecc.) rivestiti, anche solo parzialmente, con rivestimenti in materiali plastici (PMMA, PVC, PET, ABS, ecc.) e bordati con bordi in materiali plastici (PMMA, PVC, PET, ABS, ecc ). Edging of wood-based panels used in the furniture industry (particleboard, fiber, honeycomb, composite, solid wood, lamellar panels, air stems, etc.) coated, even only partially, with plastic coatings (PMMA , PVC, PET, ABS, etc.) and edged with edges in plastic materials (PMMA, PVC, PET, ABS, etc.).

Stato della tecnica preesistente. Pre-existing state of the art.

Attualmente, con la bordatura, il bordo (1C; i disegni 1 e 2 rappresentano una sezione trasversale di porzione del pannello nella zona di unione rivestimento-bordo) viene incollato al pannello, composto dal supporto (1A) ed eventuale rivestimento (1B). Seguono eventuali lavorazioni superficiali ad asportazione di materiale per modellare a piacimento l’estetica del pezzo ottenuto. Per quanto l’incollaggio possa essere fatto a regola d’arte, tra bordo e rivestimento rimangono visibili, nella zona di giunzione rivestimento-bordo (1D), dei solchi e delle irregolarità superficiali. Tali solchi e irregolarità superficiali sono visibili ad occhio nudo, peggiorando così l’estetica del pezzo. Lo sporco che si deposita nei solchi e nelle irregolarità superficiali peggiorano ancora ulteriormente l’estetica del pezzo. Per eliminare parte di questi inconvenienti estetici, attualmente si possono usare degli adesivi appositamente colorati; tale espediente però non è sufficiente ad eliminare completamente il problema estetico derivato dalla presenza dei solchi e delle irregolarità superficiali. Currently, with the edging, the edge (1C; drawings 1 and 2 represent a cross section of a portion of the panel in the lining-edge joining area) is glued to the panel, consisting of the support (1A) and any lining (1B). This is followed by any surface processing to remove material to model the aesthetics of the piece obtained as desired. Although gluing can be done in a workmanlike manner, between the edge and the lining, the grooves and surface irregularities remain visible in the lining-edge junction area (1D). These grooves and surface irregularities are visible to the naked eye, thus worsening the aesthetics of the piece. The dirt that settles in the grooves and surface irregularities further worsens the aesthetics of the piece. In order to eliminate part of these aesthetic drawbacks, at present it is possible to use specially colored adhesives; however, this expedient is not sufficient to completely eliminate the aesthetic problem deriving from the presence of grooves and surface irregularities.

DESCRIZIONE (2/3) DESCRIPTION (2/3)

Esposizione dell’invenzione Presentation of the invention

Per risolvere i problemi sopra citati di presenza di solchi e di irregolarità superficiali nella zona di giunzione rivestimento-bordo (1D), che potrebbero peggiorare l’estetica del pezzo, si è pensato di saldare bordo e rivestimento nella zona di giunzione stessa. La saldatura può essere fatta se bordo e rivestimento sono costituiti da materiali plastici. Con la saldatura si ha un’intima fusione tra bordo (2G) e rivestimento (2F) del supporto (2E) nella zona di giunzione (2H). In questo modo, e con eventuali classiche lavorazioni ad asportazione di materiale, si può ottenere una zona di giunzione (2H) priva di solchi e di irregolarità superficiali, eliminando così la possibile causa di un peggioramento estetico. To solve the aforementioned problems of the presence of grooves and surface irregularities in the lining-edge junction area (1D), which could worsen the aesthetics of the piece, it was decided to weld edge and lining in the junction area itself. Welding can be done if the edge and lining are made of plastic materials. With welding, there is an intimate fusion between the edge (2G) and the coating (2F) of the support (2E) in the joint area (2H). In this way, and with any classic material removal processes, it is possible to obtain a joint area (2H) free of grooves and surface irregularities, thus eliminating the possible cause of an aesthetic deterioration.

Non sarà quindi più visibile la linea di giunzione (ID) e Io sporco non potrà più depositarsi nei solchi e nelle irregolarità superficiali. Per eseguire la saldatura ci si può avvalere delle comuni tecniche utilizzate nella saldatura dei materiali plastici e quindi saldatura ultrasonica, ad alta frequenza, a vibrazione, a laser, a elementi riscaldanti, a getto d’aria calda, ad attrito o a riporto di materiale. La saldatura potrebbe anche in alcuni casi sostituire parzialmente o completamente l’incollaggio del bordo tramite adesivi. The joint line (ID) will therefore no longer be visible and dirt will no longer be able to deposit in the furrows and surface irregularities. To perform the welding, you can use the common techniques used in the welding of plastic materials and then ultrasonic, high frequency, vibration, laser, heating elements, hot air jet, friction or material coating welding. Welding could also in some cases partially or completely replace the edge gluing with adhesives.

DESCRIZIONE (3/3) DESCRIPTION (3/3)

Esempio di attuazione dell’invenzione Example of implementation of the invention

Per esempio, alle classiche macchine che eseguono la bordatura di pannelli si può aggiungere una zona di esecuzione della saldatura. Solitamente le bordatrici hanno una zona di accoppiamento (incollaggio) (3M; il disegno 3 è una schematizzazione di un processo di bordatura) dei bordo (3L) al pannello rivestito (31) a cui segue una zona di asportazione di materiale (3N). Si può aggiungere tra la zona di accoppiamento (3M) e la zona di asportazione del materiale (3N) una zona di saldatura (30) nella quale è presente un saldatore ultrasonico che esegue la saldatura in corsa del bordo sul rivestimento. For example, a welding execution area can be added to the classic machines that perform the edge banding of panels. Usually the edge banding machines have a coupling (gluing) area (3M; drawing 3 is a schematic of a beading process) of the edge (3L) to the coated panel (31) followed by a material removal area (3N). A welding area (30) can be added between the coupling area (3M) and the material removal area (3N) in which there is an ultrasonic welder that performs the welding in the run of the edge on the coating.
