DISPOSITIVO REGOLABILE DI DISTRIBUZIONE COLLA DI UN GRUPPO GOFFRATORE-LAMINATORE, RELATIVO GRUPPO E METODO DI REGOLAZIONE ADJUSTABLE GLUE DISTRIBUTION DEVICE OF AN EMBOSSING-LAMINATOR GROUP, RELATIVE GROUP AND ADJUSTMENT METHOD
------ ------
La presente invenzione si riferisce ad un dispositivo regolabile di distribuzione colla di un gruppo goffratore-laminatore, a un relativo gruppo e ad un metodo di regolazione. The present invention refers to an adjustable glue distribution device of an embossing-laminating unit, to a relative unit and to an adjustment method.
In generale i gruppi di goffratura-laminazione per carta comprendono almeno un rullo goffratore, almeno un controrullo goffratore, almeno un rullo di distribuzione della colla e almeno un rullo di dosatore della medesima colla. In general, the embossing-laminating units for paper comprise at least one embossing roller, at least one counter-embossing roller, at least one glue distribution roller and at least one metering roller for the same glue.
Generalmente il rullo goffratore risulta essere da un lato in battuta con il controrullo goffratore, per goffrare almeno un velo di carta alimentata, e da un altro lato con il rullo di distribuzione per distribuire la colla sul medesimo velo di carta goffrato. Generally, the embossing roller is on one side in abutment with the embossing counter roller, to emboss at least one web of fed paper, and on the other side with the distribution roller to distribute the glue on the same web of embossed paper.
Il rullo dosatore in tali gruppi ha lo scopo di alimentare la colla sul rullo di distribuzione e per far ciò esso à ̈ sua volta accoppiato con la sua superficie esterna da un lato con un serbatoio di colla e da un altro lato con il rullo di distribuzione. The dosing roller in these groups has the purpose of feeding the glue onto the distribution roller and to do this it is in turn coupled with its external surface on one side with a glue tank and on the other side with the distribution roller. .
Grazie a tale accoppiamento di rulli, in cui il rullo dosatore à ̈ generalmente detto “retinato†e il rullo di distribuzione “cliché†, si procede a prelevare la colla dal serbatoio, detto anche “camera a racla†e a disporla sull’almeno un velo goffrato passante sul medesimo cliché. Thanks to this coupling of rollers, in which the dosing roller is generally called â € œretinatedâ € and the distribution roller â € œclickâ €, the glue is collected from the tank, also known as the â € œ doctor blade chamberâ € and a place it on at least one embossed veil passing through the same clichà ©.
Tuttavia i gruppi di goffratura-laminazione appena descritti presentano alcuni inconvenienti, in particolare derivanti dalla necessità di cambiare il formato, vale a dire la larghezza, della carta alimentata nel gruppo stesso, che può ad esempio variare con il variare del fornitore. However, the embossing-laminating units just described have some drawbacks, in particular deriving from the need to change the format, that is to say the width, of the paper fed into the unit itself, which can, for example, vary with the variation of the supplier.
Infatti, per un corretto funzionamento del dispositivo di distribuzione della colla, la carta alimentata deve avere larghezza maggiore dello sviluppo assiale del rullo cliché di circa 40 mm. In fact, for the glue distribution device to work correctly, the fed paper must have a width greater than the axial development of the clichà © roller by approximately 40 mm.
Diversamente si erogherebbe la colla non solo sulla carta ma anche sulla superficie del rullo goffratore contro la quale il rullo cliché agisce e che non à ̈ coperta dalla carta, provocando svantaggiosamente oltre allo spreco della colla anche la rottura della carta durante la goffratura e, in particolare, un malfunzionamento del gruppo in generale dovuto all’imbrattamento del rullo goffratore. Otherwise the glue would be dispensed not only on the paper but also on the surface of the embossing roller against which the clichà © roller acts and which is not covered by the paper, causing disadvantageously not only the waste of the glue but also the breaking of the paper during embossing and, in particular, a malfunction of the unit in general due to contamination of the embossing roller.
Attualmente, al variare della larghezza della carta alimentata al gruppo goffratore-laminatore si procede a sostituire di volta in volta il rullo cliché, con un rullo avente sviluppo leggermente inferiore alla larghezza della carta che viene alimentata nel gruppo stesso. At present, upon varying the width of the paper fed to the embossing-laminating unit, the clichà © roller is replaced from time to time with a roller having a development slightly smaller than the width of the paper which is fed into the group itself.
Tale procedura à ̈, come si deduce, del tutto svantaggiosa sia da un punto di vista economico che produttivo richiedendo sia costi elevati per i rulli cliché da sostituire di volta in volta sia prolungati tempi di inoperosità del gruppo durante tale sostituzione dei rulli. This procedure is, as can be deduced, completely disadvantageous both from an economic and production point of view, requiring both high costs for the clichà © rollers to be replaced from time to time and prolonged downtime of the unit during this replacement of the rollers.
Sono state anche proposte soluzioni volte ad intervenire all’interfaccia tra la camera racla ed il rullo retinato per applicare sul rullo retinato la colla solo sulla porzione del suo sviluppo assiale effettivamente in corrispondenza con la carta, trasferendo quindi sul rullo cliché la colla solo in corrispondenza di tale porzione. Solutions have also been proposed aimed at intervening at the interface between the doctor blade chamber and the anilox roller to apply the glue on the anilox roller only on the portion of its axial development actually in correspondence with the paper, thus transferring only the glue onto the clichà © roller at this portion.
Queste soluzioni comportano tuttavia una complicazione tecnica all’interfaccia tra una parte fissa, il serbatoio della colla, ed una parte mobile, il rullo retinato, dì per sé critica ad esempio per quanto riguarda le tenute striscianti, e non sembrano aver raggiunto il compromesso ottimale tra efficienza e funzionalità . However, these solutions involve a technical complication at the interface between a fixed part, the glue tank, and a moving part, the anilox roll, which is critical for example as regards sliding seals, and do not seem to have reached the optimal compromise between efficiency and functionality.
Scopo della presente invenzione à ̈ quello di realizzare un dispositivo regolabile di distribuzione colla di un gruppo goffratore-laminatore, un relativo gruppo ed un metodo di regolazione in grado di adattarsi alle varie larghezze della carta da incollare senza prevedere la sostituzione di alcun rullo del gruppo. The purpose of the present invention is to provide an adjustable glue distribution device for an embossing-laminating unit, a relative unit and a regulation method capable of adapting to the various widths of the paper to be glued without requiring the replacement of any roller of the unit. .
Scopo della presente invenzione à ̈ quello di realizzare un dispositivo regolabile di distribuzione colla di un gruppo goffratore-laminatore, un relativo gruppo ed un metodo di regolazione in grado di risolvere gli inconvenienti sopra citati della tecnica nota in una maniera estremamente semplice, economica e particolarmente funzionale. The object of the present invention is to provide an adjustable glue distribution device for an embossing-laminating unit, a relative unit and a regulation method capable of solving the aforementioned drawbacks of the prior art in an extremely simple, economical and particularly functional.
Questi scopi secondo la presente invenzione sono raggiunti realizzando un dispositivo regolabile di distribuzione colla di un gruppo goffratore-laminatore, un relativo gruppo ed un metodo di regolazione come esposto nelle rivendicazioni indipendenti. These objects according to the present invention are achieved by realizing an adjustable glue distribution device of an embossing-laminating unit, a relative unit and a regulation method as set out in the independent claims.
Ulteriori caratteristiche sono previste nelle rivendicazioni dipendenti. Further characteristics are provided in the dependent claims.

le figure 4 e 5 mostrano schematicamente due diverse forme di realizzazione esemplificative del dispositivo secondo l’invenzione. Figures 4 and 5 schematically show two different exemplary embodiments of the device according to the invention.
Con riferimento alle figure, viene mostrato un dispositivo regolabile di distribuzione colla di un gruppo goffratore-laminatore, complessivamente indicato con 10. With reference to the figures, an adjustable glue distribution device of an embossing-laminating unit is shown, indicated as a whole with 10.
Con il termine colla 11 si intende in generale una sostanza collante preferibilmente a comportamento fluido. The term glue 11 generally refers to an adhesive substance preferably with a fluid behavior.
Come visibile in figura 1 il dispositivo regolabile di distribuzione colla 10, oggetto della presente invenzione, Ã ̈ applicabile ad un gruppo goffratore-laminatore 100. As can be seen in Figure 1, the adjustable glue distribution device 10, object of the present invention, can be applied to an embossing-laminating unit 100.
Secondo l’esempio realizzativo mostrato nella sopra citata figura 1 tale gruppo goffratore-laminatore 100 comprende un rullo goffratore 120 e un controrullo goffratore 110, tra cui à ̈ rinviato almeno un velo di carta 101. According to the embodiment shown in the aforementioned figure 1, this embossing-laminating unit 100 comprises an embossing roller 120 and an embossing counter-roller 110, between which at least one web of paper 101 is returned.
Il dispositivo regolabile di distribuzione colla 10 comprende un rullo di distribuzione 12 della colla ed un rullo dosatore 13 della medesima colla, aventi secondo l’invenzione il medesimo sviluppo assiale. The adjustable glue distribution device 10 comprises a glue distribution roller 12 and a metering roller 13 for the same glue, having the same axial development according to the invention.
In particolare, il rullo goffratore 120 à ̈ rispettivamente accoppiato lungo due differenti generatrici con il controrullo goffratore 110 per goffrare l’almeno un velo di carta 101 e con il rullo di distribuzione 12 che distribuisce la colla sull’almeno un velo di carta 101 goffrato. In particular, the embossing roller 120 is respectively coupled along two different generatrices with the embossing counter roller 110 to emboss the at least one web of paper 101 and with the distribution roller 12 which distributes the glue on the at least one web of paper 101 embossed.
Il rullo dosatore 13 Ã ̈ sua volta rispettivamente accoppiato lungo due differenti generatrici rispettivamente con un serbatoio 14 contenente colla 11 per prelevare la colla e con il rullo di distribuzione 12 per alimentare la colla 11 prelevata sul rullo di distribuzione 12 lungo una porzione di accoppiamento 17. The metering roller 13 is in turn respectively coupled along two different generators respectively with a tank 14 containing glue 11 to pick up the glue and with the distribution roller 12 to feed the glue 11 picked up on the distribution roller 12 along a coupling portion 17 .
Il serbatoio 14 per la colla 11 à ̈ costituito da una cosiddetta camera a racla, comprendente un corpo sagomato a “C†, atto a contenere la colla, il quale à ̈ disposto lateralmente lungo sostanzialmente tutto lo sviluppo del rullo dosatore 13. In particolare il corpo sagomato a “C†del serbatoio di colla 14 à ̈ delimitato alle estremità da due pareti laterali 14’ provviste all’estremità affacciata al rullo dosatore 13 di elementi a tenuta, quali ad esempio guarnizioni. Le pareti laterali 14’ si estendono infatti fino alla prossimità della porzione superficiale laterale del rullo dosatore 13, determinando lo sviluppo assiale del rullo dosatore 13 su cui viene distribuita la colla. Il rullo di distribuzione 12 ed il rullo dosatore 13 sono ognuno montato su fianchi 15 tra loro indipendenti e sono dotati di proprie motorizzazioni 16. The tank 14 for the glue 11 consists of a so-called doctor blade chamber, comprising a â € œCâ € shaped body, suitable for containing the glue, which is arranged laterally along substantially the entire length of the dosing roller 13. In in particular, the â € œCâ € shaped body of the glue tank 14 is delimited at the ends by two side walls 14â € ™ provided at the end facing the metering roller 13 with sealing elements, such as gaskets. The side walls 14 extend in fact up to the proximity of the lateral surface portion of the metering roller 13, determining the axial development of the metering roller 13 on which the glue is distributed. The distribution roller 12 and the metering roller 13 are each mounted on independent sides 15 and are equipped with their own motors 16.
Secondo l’invenzione, almeno uno dei rulli di distribuzione 12 e/o dosatore 13 à ̈ mobile assialmente rispetto ad un asse di mezzeria x del gruppo 100 per incrementare e/o diminuire la larghezza della porzione di accoppiamento 17 tra il rullo dosatore 13 e il rullo di distribuzione 12. Con asse di mezzeria x si intende l’asse parallelo alla direzione di alimentazione dell’almeno un velo di carta 101 passante per la mezzeria del rullo goffratore 120. According to the invention, at least one of the distribution rollers 12 and / or metering roller 13 is axially movable with respect to a center line x of the group 100 to increase and / or decrease the width of the coupling portion 17 between the metering roller 13 and the distribution roller 12. With the center line axis x is meant the axis parallel to the feed direction of the at least one web of paper 101 passing through the center line of the embossing roller 120.
Preferibilmente, sia il rullo di distribuzione 12 sia il rullo dosatore 13 sono mobili assialmente in direzioni tra loro opposte e ortogonali rispetto all’asse di mezzeria x, schematizzato con le frecce F. Traslando ognuno dei rulli 12, 13 della stessa quantità in direzione opposta, simmetricamente rispetto all’asse x, si ottiene che l’almeno un velo di carta 101 riceve la colla in una posizione centrata rispetto all’asse di mezzeria x del gruppo. Secondo l’invenzione, il rullo dosatore 13 trasla rimanendo solidale con il serbatoio della colla 14. Preferably, both the distribution roller 12 and the metering roller 13 are axially movable in opposite directions and orthogonal with respect to the centerline axis x, schematized with the arrows F. Moving each of the rollers 12, 13 by the same amount in the direction opposite, symmetrically with respect to the x axis, we obtain that the at least one web of paper 101 receives the glue in a position centered with respect to the x axis of the group. According to the invention, the metering roller 13 translates while remaining integral with the glue tank 14.
A tale scopo à ̈ schematizzato in figura 2 il posizionamento reciproco del rullo di distribuzione 12 e del rullo dosatore 13 quando à ̈ alimentato un velo di carta 101 di larghezza massima Y pari sostanzialmente alla larghezza del rullo dosatore 13. Più precisamente, il velo di carta 101 à ̈ poco più largo del rullo dosatore 13, ad esempio maggiore di circa 40 mm distribuiti sui lati opposti. For this purpose, Figure 2 shows the mutual positioning of the distribution roller 12 and the metering roller 13 when a web of paper 101 of maximum width Y is fed, substantially equal to the width of the metering roller 13. More precisely, the web of paper 101 is slightly wider than the measuring roller 13, for example greater than about 40 mm distributed on opposite sides.
In figura 3 à ̈ invece schematizzato il posizionamento reciproco del rullo di distribuzione 12 e del rullo dosatore 13 quando à ̈ alimentato un velo di carta 101 ad esempio di larghezza Y’, inferiore alla larghezza del rullo dosatore 13. I rulli 12 e 13 sono accoppiati lungo una porzione del loro sviluppo assiale, disposta simmetricamente rispetto all’asse x, sostanzialmente pari alla larghezza Y’ della carta e più precisamente di poco inferiore alla stessa. Figure 3, on the other hand, shows the reciprocal positioning of the distribution roller 12 and the metering roller 13 when a web of paper 101 is fed, for example of width Yâ € ™, less than the width of the metering roller 13. The rollers 12 and 13 they are coupled along a portion of their axial development, arranged symmetrically with respect to the x axis, substantially equal to the paper width Yâ € ™ and more precisely slightly less than it.
In questa configurazione, il rullo dosatore 13 riceve la colla 11 su tutta la sua superficie, ma trasferisce al rullo di distribuzione 12 solo quella che si viene a trovare in corrispondenza della porzione di accoppiamento 17 affacciata. La colla che non à ̈ trasferita sul rullo di distribuzione 12 à ̈ raccolta e riciclata tramite mezzi non mostrati. In this configuration, the metering roller 13 receives the glue 11 over its entire surface, but transfers to the distribution roller 12 only that which is found in correspondence with the facing coupling portion 17. Glue that is not transferred to the dispensing roller 12 is collected and recycled by means not shown.
Il rullo di distribuzione 12 riceve la colla 11 solo sulla porzione del suo sviluppo assiale affacciata al rullo dosatore 13, che coincide sostanzialmente con la larghezza della carta Y†̃. La porzione del rullo di distribuzione 12 non affacciata al rullo dosatore 13 e non ricoperta dal velo di carta 101 viene direttamente a contatto con il rullo goffratore 120, ma non à ̈ interessata dalla colla 11 e pertanto non rischia di sporcare lo stesso. The distribution roller 12 receives the glue 11 only on the portion of its axial extension facing the metering roller 13, which substantially coincides with the width of the paper Yâ € ̃. The portion of the distribution roller 12 not facing the metering roller 13 and not covered by the paper film 101 comes into direct contact with the embossing roller 120, but is not affected by the glue 11 and therefore does not risk dirtying it.
Secondo l’invenzione, il rullo dosatore 13 e/o il rullo di distribuzione 12, assieme alle rispettive motorizzazioni 16, sono reciprocamente traslabili in direzione assiale in modo solidale con i relativi fianchi 15 (figura 4) oppure sono traslabili assialmente rispetto ad essi (figura 5) con l’ausilio di mezzi di guida e di regolazione non mostrati. According to the invention, the metering roller 13 and / or the distribution roller 12, together with the respective motorizations 16, are mutually translatable in an axial direction integrally with the relative sides 15 (figure 4) or they can be translated axially with respect to them (figure 5) with the aid of guide and adjustment means not shown.
Risulta del tutto agevole comprendere quale sia il funzionamento del dispositivo 10 oggetto del trovato. It is quite easy to understand what the operation of the device 10 according to the invention is.
Secondo l’invenzione il rullo dosatore 13 ed il rullo di distribuzione 12 sono reciprocamente traslati in direzione assiale per essere tra loro affacciati lungo la porzione di accoppiamento 17 del loro sviluppo assiale, che à ̈ sostanzialmente coincidente, e più in particolare di poco inferiore, alla larghezza dell’almeno un velo di carta 101. According to the invention, the metering roller 13 and the distribution roller 12 are mutually translated in an axial direction to face each other along the coupling portion 17 of their axial development, which is substantially coincident, and more in particular slightly lower , at the width of at least one sheet of paper 101.
Secondo l’invenzione quindi si evitano eventuali accidentali erogazioni di colla sulla superficie del rullo goffratore 120 del gruppo goffratore-laminatore 100 non coperte dall’almeno un velo 101, come detto nel caso di rullo dosatore 13 con sviluppo maggiore della larghezza del carta 101 da incollare, diminuendo la porzione del rullo di distribuzione 12 affacciata al rullo dosatore 13 a seconda della larghezza dell’almeno un velo 101 da incollare. According to the invention, therefore, any accidental dispensing of glue on the surface of the embossing roller 120 of the embossing-laminating unit 100 not covered by at least one web 101 is avoided, as mentioned in the case of the measuring roller 13 with development greater than the width of the paper 101 to be glued, decreasing the portion of the distribution roller 12 facing the metering roller 13 according to the width of the at least one web 101 to be glued.
Il dispositivo regolabile di distribuzione colla di un gruppo goffratore-laminatore ed il relativo gruppo oggetto della presente invenzione hanno il vantaggio di non richiedere la sostituzione del rullo di distribuzione 12, né l’intervento sull’interfaccia tra la il serbatoio della colla 14 e il rullo dosatore 13. The adjustable glue distribution device of an embossing-laminator group and the relative group object of the present invention have the advantage of not requiring the replacement of the distribution roller 12, nor the intervention on the interface between the glue tank 14 and the dosing roller 13.
Il dispositivo regolabile di distribuzione colla di un gruppo goffratore-laminatore ed il relativo gruppo così concepiti sono suscettibili di numerose modifiche e varianti, tutte rientranti nell’invenzione; inoltre tutti i dettagli sono sostituibili da elementi tecnicamente equivalenti. In pratica i materiali utilizzati, nonché le dimensioni, potranno essere qualsiasi a seconda delle esigenze tecniche. The adjustable glue distribution device of an embossing-laminating unit and the relative unit thus conceived are susceptible of numerous modifications and variations, all of which are within the scope of the invention; furthermore, all the details can be replaced by technically equivalent elements. In practice, the materials used, as well as the dimensions, can be any according to the technical requirements.
