Descrizione Description

APPARATO PER LA REALIZZAZIONE DI UN FILM ESTENSIBILE COSTITUITO DA STRISCE BORDATE AVVOLTE SU UNA STESSA BOBINA; EQUIPMENT FOR THE REALIZATION OF AN EXTENSIBLE FILM CONSISTING OF EDGED STRIPS WRAPPED ON A SAME REEL;

La presente innovazione riguarda un apparato per la produzione di un film estensibile per imballaggi che, in fase di produzione, viene diviso in strisce longitudinali che vengono sottoposte a bordatura prima di essere avvolte sulla bobina di raccolta. The present innovation relates to an apparatus for the production of an extensible film for packaging which, during the production phase, is divided into longitudinal strips which are subjected to edging before being wound on the collection reel.

In questo modo, non è necessaria alcuna operazione successiva a quella di produzione. This way, no post-production steps are required.

Questo comporta evidentemente costi aggiuntivi sia in termini di tempo, di lavoro, di energia elettrica, e di spazio occupato in magazzino, che deve prevedere il posto per le bobine da lavorare e per quelle lavorate. This obviously involves additional costs both in terms of time, work, electricity, and space occupied in the warehouse, which must provide a place for the reels to be processed and for those processed.

Scopo del presente modello è di superare detti problemi fornendo una macchina per la produzione di film estensibile, la quale, rispetto alle macchine attualmente note, oltre ad essere dotata di mezzi per tagliare il film in strisce longitudinali è anche dotata di mezzi per ribordare dette strisce prima del loro passaggio nell'oscillatore per essere poi avvolte sulla bobina di raccolta. The object of the present model is to overcome said problems by providing a machine for the production of stretch film, which, compared to currently known machines, in addition to being equipped with means for cutting the film into longitudinal strips, is also equipped with means for edge-wrapping said strips. before their passage in the oscillator to be then wound on the collection coil.

Una migliore comprensione dell'innovazione si avrà con la seguente descrizione dettagliata e con riferimento alla figura che illustra, a solo titolo esemplificativo non limitativo, una preferita forma realizzativa. A better understanding of the innovation will be obtained with the following detailed description and with reference to the figure which illustrates, by way of non-limiting example, a preferred embodiment.

Nei disegni: In the drawings:

la figura 1 è una vista schematica in pianta di un apparato di tipo noto per la produzione di film estensibili che vengono raccolti interi sulle bobine di raccolta; Figure 1 is a schematic plan view of an apparatus of a known type for the production of stretch films which are collected whole on the collection reels;

la figura 2, analoga alla precedente, mostra l'apparato secondo la presente innovazione, in cui, oltre ai mezzi di taglio per dividere il film in strisce, sono presenti mezzi per la bordatura delle stesse prima di avvolgerle sulla bobina di raccolta. Figure 2, similar to the previous one, shows the apparatus according to the present invention, in which, in addition to the cutting means for dividing the film into strips, there are means for beading them before winding them on the collection reel.

Secondo il presente modello di utilità, i mezzi di taglio e bordatura TB sono disposti a valle del rullo dell'estrusore (chill-roll), e prima dell'oscillatore 21, in modo che un singolo oscillatore possa essere usato per avvolgere tutte le strisce bordate sulla bobina di raccolta. According to the present utility model, the cutting and edging means TB are arranged downstream of the extruder roller (chill-roll), and before the oscillator 21, so that a single oscillator can be used to wind all the strips. edged on the take-up reel.

E' preferibile che il misuratore di spessore 20 sia disposto dopo il gruppo di taglio e bordatura TB, in modo da verificare le dimensioni delle strisce finite . It is preferable that the thickness gauge 20 is arranged after the cutting and edging unit TB, so as to check the dimensions of the finished strips.

Nell'esempio illustrato, i mezzi di taglio e quelli di bordatura sono raccolti in un unico insieme, detto, appunto, gruppo di taglio e bordatura TB . E' però evidente che la stessa funzionalità si ottiene predisponendo i mezzi di taglio separati rispetto ai mezzi di bordatura, questi ultimi a valle dei primi. In the illustrated example, the cutting means and the edging means are gathered in a single assembly, called, precisely, the cutting and edging unit TB. However, it is evident that the same functionality is obtained by arranging the cutting means separate from the beading means, the latter downstream of the former.

I mezzi di taglio possono essere costituiti da normali coltelli rotanti o altri sistemi noti, mentre i mezzi di bordatura possono essere costituiti da un rullo con anelli sporgenti appositamente posizionati coassialmente al rullo stesso, per applicare la bordatura alle strisce appena tagliate e mantenerle separate per il misuratore di spessore e 1'oscillatore . The cutting means can be constituted by normal rotating knives or other known systems, while the edging means can be constituted by a roller with protruding rings specially positioned coaxially to the roller itself, to apply the edging to the strips just cut and keep them separate for the thickness gauge and the oscillator.

Vantaggiosamente, detto oscillatore 21, permette di raccogliere le strisce sulla bobina evitando la sovrapposizione delle bordature, cosa che renderebbe difficile o impossibile il successivo svolgimento del film. Advantageously, said oscillator 21 allows to collect the strips on the reel avoiding the overlapping of the edges, which would make the subsequent unwinding of the film difficult or impossible.

Infine, è anche opportuno predisporre, in corrispondenza dei mezzi di taglio, un aspiratore di cimose per evitare intasamenti della macchina, che convoglia le rifilature al macinatore di rifili 27. Finally, it is also advisable to provide, in correspondence with the cutting means, a selvedge aspirator to avoid clogging of the machine, which conveys the trimmings to the trimmings grinder 27.

La presente innovazione è stata descritta ed illustrata in una sua preferita forma realizzativa, ma è chiaro che qualunque tecnico esperto del ramo potrà apportarvi modifiche e/o sostituzioni equivalenti senza peraltro esulare dall'ambito di tutela della presente privativa industriale. The present innovation has been described and illustrated in a preferred embodiment thereof, but it is clear that any technician skilled in the art can make equivalent modifications and / or replacements without however going beyond the scope of protection of this industrial patent.
