"Unità di lavorazione di un foglio di incarto." "Processing unit of a wrapping sheet."
La presente invenzione à ̈ relativa ad una unità di lavorazione di un foglio di incarto destinato alla formazione di un involucro. The present invention relates to a unit for processing a sheet of wrapping intended for forming an envelope.
La presente invenzione trova impiego particolarmente vantaggioso nella realizzazione di pacchetti di sigarette, cui la trattazione che segue farà esplicito riferimento senza per questo perdere in generalità . The present invention finds particularly advantageous use in the production of packets of cigarettes, to which the following discussion will make explicit reference without thereby losing generality.
Un pacchetto di sigarette di tipo morbido o semirigido comprende normalmente un incarto interno costituito da un gruppo di sigarette avvolto in un foglio di incarto interno costituito usualmente da carta metallizzata, ed un involucro esterno realizzato avvolgendo il gruppo di sigarette contenuto nell’incarto interno in un foglietto di materiale (solitamente) cartaceo. A soft or semi-rigid cigarette packet normally comprises an internal wrapping consisting of a group of cigarettes wrapped in an internal wrapping sheet usually made of metallized paper, and an external wrapping made by wrapping the group of cigarettes contained in the inner wrapping in a sheet of (usually) paper material.
I pacchetti di sigarette di tale tipo presentano frequentemente gli spigoli longitudinali in qualche misura rotondeggianti, mentre à ̈ considerato vantaggioso e preferibile che tali spigoli si presentino quanto più possibile vivi. Packets of cigarettes of this type frequently have somewhat rounded longitudinal edges, while it is considered advantageous and preferable for such edges to be as sharp as possible.
Scopo della presente invenzione à ̈ fornire una unità di lavorazione di un foglio di incarto utilizzabili, in particolare, per la produzione di pacchetti di sigarette di tipo morbido, la quale consenta di ottenere pacchetti presentanti gli spigoli longitudinali piegati in maniera netta e non rotondeggianti. The object of the present invention is to provide a unit for processing a sheet of wrapping which can be used, in particular, for the production of packets of soft cigarettes, which allows to obtain packets having the longitudinal edges folded in a neat way and not rounded.
In accordo con la presente invenzione viene fornita una unità di lavorazione di un foglio di incarto secondo quanto stabilito nelle rivendicazioni allegate. In accordance with the present invention there is provided a unit for processing a sheet of wrapping according to what is established in the attached claims.
La presente invenzione verrà ora descritta con riferimento al disegno annesso, che ne illustra un esempio di attuazione non limitativo, in cui: The present invention will now be described with reference to the attached drawing, which illustrates a non-limiting example of implementation, in which:
- la figura 1 Ã ̈ una vista in assonometria di un pacchetto morbido per sigarette; - figure 1 is an isometric view of a soft packet for cigarettes;
- la figura 2 à ̈ una vista in pianta di un foglietto costituente l’incarto esterno del pacchetto morbido per sigarette della figura 1; e - figure 2 is a plan view of a leaflet constituting the outer wrapping of the soft packet for cigarettes of figure 1; And
- la figura 3 à ̈ una vista frontale schematica di una unità di lavorazione di fogli di incarto realizzata in accordo con la presente invenzione. Figure 3 is a schematic front view of a wrapping sheet processing unit made in accordance with the present invention.
Nella figura 1 con il numero 1 à ̈ indicato nel suo complesso un pacchetto morbido per sigarette, il quale comprende un incarto 2 interno morbido e chiuso, di forma parallelepipeda a base rettangolare, ed un contenitore o involucro 3 esterno a tazza presentante una estremità 4 superiore aperta, che rende accessibile una corrispondente parete 5 superiore dell'involucro 2 interno. In figure 1, the number 1 indicates as a whole a soft packet for cigarettes, which comprises a soft and closed inner wrapping 2, of parallelepiped shape with a rectangular base, and an outer cup-shaped container or wrapping 3 having an end 4 open upper wall, which makes accessible a corresponding upper wall 5 of the inner casing 2.
L'incarto 2 interno à ̈ realizzato ripiegando, attorno ad un gruppo (non illustrato) di sigarette, un foglio di incarto interno costituito da carta metallizzata, materiale plastico stratificato o simile. The internal wrapping 2 is made by folding, around a group (not shown) of cigarettes, an inner wrapping sheet made of metallized paper, laminated plastic material or similar.
Secondo quanto illustrato, in particolare, nella figura 2, il contenitore 3 esterno à ̈ realizzato ripiegando, attorno all’incarto 2 interno, un foglio 3’ di incarto esterno (mostrato in pianta nella figura 2) che à ̈ provvisto di una pluralità di linee 6 di piegatura preindebolite. As illustrated, in particular, in figure 2, the outer container 3 is made by folding, around the inner wrapping 2, a sheet 3â € ™ of outer wrapping (shown in plan view in figure 2) which is provided with a plurality of pre-weakened folding lines 6.
Nella figura 3, con il numero 7 à ̈ indicata nel suo complesso una unità lavorazione di fogli di incarto atta ad essere utilizzata in una apparecchiatura (non illustrata) per la produzione dei citati pacchetti 1 morbidi, oppure di pacchetti semirigidi (non illustrati) del tipo descritto nella domanda di brevetto EP0633202A2. In figure 3, the number 7 indicates as a whole a wrapping sheet processing unit suitable for use in an apparatus (not shown) for the production of the aforementioned soft packets 1, or of semi-rigid packets (not shown) of the type described in patent application EP0633202A2.
Durante il transito attraverso l’unità 7 un nastro 8 di materiale di incarto continuo svolto da un bobina non illustrata viene trascinato fra due rulli goffratori 9 e 10, rispettivamente sinistro e destro nella figura 3, sostanzialmente tangenti fra loro lungo una generatrice e supportati coassialmente da rispettivi alberi 11 e 12 controrotanti. I rulli goffratori 9 e 10 sono in grado di dotare il nastro 8 delle citate linee 6 di piegatura pre-indebolite, in quanto uno dei rulli 9, 10 à ̈ dotato di rilievi (non illustrati) definenti una matrice di goffratura e riproducenti le dimensioni e le forme delle linee di piegatura stesse (impronta di goffratura), mentre l’altro rullo 9, 10 presenta delle solcature (non illustrate) coniugabili ciclicamente con tali rilievi. Le solcature e i corrispondenti rilievi dei rulli goffratori 9 e 10 si coniugano nella zona di tangenza fra i rulli 9 e 10 stessi, imprimendo nel nastro 8 le linee 6 di piegatura pre-indebolite (impronta di goffratura). During the transit through unit 7, a ribbon 8 of continuous wrapping material unwound from a reel (not shown) is dragged between two embossing rollers 9 and 10, respectively left and right in Figure 3, substantially tangent to each other along a generatrix and supported coaxially by respective counter-rotating shafts 11 and 12. The embossing rollers 9 and 10 are able to provide the web 8 with the aforementioned pre-weakened folding lines 6, since one of the rollers 9, 10 is equipped with reliefs (not shown) defining an embossing matrix and reproducing the dimensions and the shapes of the folding lines themselves (embossing imprint), while the other roller 9, 10 has grooves (not shown) which can be conjugated cyclically with these reliefs. The grooves and the corresponding projections of the embossing rollers 9 and 10 are joined in the tangency area between the rollers 9 and 10 themselves, impressing the pre-weakened folding lines 6 in the strip 8 (embossing imprint).
Secondo una variante, uno dei rulli 9, 10 à ̈ dotato di rilievi (non illustrati) riproducenti le dimensioni e le forme delle linee di piegatura stesse, mentre l’altro rullo 9, 10 à ̈ liscio e rivestito con un materiale resiliente, ad esempio in gomma o simile. According to a variant, one of the rollers 9, 10 is equipped with reliefs (not shown) reproducing the dimensions and shapes of the bending lines themselves, while the other roller 9, 10 is smooth and coated with a resilient material, for example made of rubber or similar.
A valle dei rulli goffratori 9 e 10, con riferimento al verso di avanzamento del nastro 8, à ̈ situato un dispositivo di taglio indicato nel suo complesso con 14, comprendente due coltelli rotanti 15 e 16, rispettivamente sinistro e destro nella figura 3, supportati coassialmente da rispettivi alberi 17 e 18. Tali coltelli 15 e 16 sono controrotanti e sono dotati di rispettive lame 15’, 16’ atte a portarsi ciclicamente in condizione di reciproca tangenza per separare in successione dal nastro 8 dei foglietti 3’ dotati delle citate linee 6 di piegatura pre-indebolite. Downstream of the embossing rollers 9 and 10, with reference to the direction of advancement of the web 8, there is a cutting device indicated as a whole with 14, comprising two rotating knives 15 and 16, respectively left and right in Figure 3, supported coaxially by respective shafts 17 and 18. These knives 15 and 16 are counter-rotating and are equipped with respective blades 15â € ™, 16â € ™ suitable for cyclically moving into a condition of mutual tangency to separate in succession from the belt 8 some sheets 3â € ™ equipped of the aforementioned pre-weakened folding lines 6.
I foglietti 3’ manipolati dall’unità 7 di lavorazione e dal dispositivo di taglio 14 vengono quindi ripiegati, lungo le linee 6 di piegatura pre-indebolite, attorno ad un gruppo di articoli da fumo costituiti, in particolare, da sigarette, per realizzare una confezione di articoli da fumo costituita, in particolare, da un pacchetto 1 di sigarette The sheets 3 'handled by the processing unit 7 and by the cutting device 14 are then folded, along the pre-weakened folding lines 6, around a group of smoking articles consisting, in particular, of cigarettes, for making a pack of smoking articles consisting, in particular, of a pack 1 of cigarettes
Preferibilmente, i rulli goffratori 9 e 10 sono portati in rotazione da una unità elettrica motrice in grado di variare, a mezzo di una “camma elettronica†, la velocità di rotazione dei rulli stessi durante la svolgitura del nastro 8, in modo da variare l’impronta di goffratura eseguita sul nastro 8 in corrispondenza di ciascuna porzione destinata a definire il foglio 3’ di incarto. In tal modo à ̈ possibile provare diverse impronte con una medesima matrice di goffratura ed, eventualmente, provvedere ad una sostituzione della matrice con una nuova modificata da utilizzare con rotazione costante in 1:1 del rulli goffratori 9 e 10. Preferably, the embossing rollers 9 and 10 are rotated by an electric drive unit capable of varying, by means of an `` electronic cam '', the rotation speed of the rollers themselves during the unwinding of the web 8, so as to vary the embossing imprint made on the tape 8 in correspondence with each portion destined to define the wrapping sheet 3. In this way it is possible to try different impressions with the same embossing matrix and, if necessary, to replace the matrix with a new one modified to be used with constant 1: 1 rotation of the embossing rollers 9 and 10.
Per “camma elettronica†si intende un dispositivo elettronico di controllo della unità motrice in grado di variare la velocità di rotazione dei rulli goffratori. By â € œelectronic camâ € we mean an electronic control device of the drive unit capable of varying the rotation speed of the embossing rollers.
E’ opportuno precisare che l’unità 7 di lavorazione sopra descritta può venire vantaggiosamente utilizzata per realizzare delle linee 6 di piegatura pre-indebolite in qualunque tipo di fogli di incarto, quindi anche sui fogli di incarti interni di carta metallizzata, in sbozzati di cartone o cartoncino per realizzare contenitori con coperchio incernierato, in collarini di cartone o cartoncino, o in fogli di incarto di materiale termoplastico per sovraincarti. It should be noted that the processing unit 7 described above can be advantageously used to create pre-weakened folding lines 6 in any type of wrapping sheet, therefore also on the sheets of internal metallized paper wrapping, in blanks. of cardboard or cardboard to make containers with hinged lids, in cardboard or cardboard collars, or in sheets of thermoplastic material to overwrap.
Secondo una variante non illustrata della presente invenzione, l’unità 7 può comprendere più di una coppia di rulli goffratori, ciascuna coppia avendo il compito di eseguire determinate linee 6 di piegatura pre-indebolite. According to a not illustrated variant of the present invention, the unit 7 can comprise more than one pair of embossing rollers, each pair having the task of executing certain pre-weakened folding lines 6.
