Description
[0001] La presente invenzione ha per oggetto un metodo di alimentazione di materiale d’incarto in una macchina confezionatrice di prodotti e una relativa unità di alimentazione. [0001] The present invention relates to a method of feeding wrapping material into a product packaging machine and a relative feeding unit.
[0002] Secondo quanto noto le unità del tipo in oggetto comprendono dei mezzi svolgiteli di un nastro continuo di materiale cartaceo da una bobina, un dispositivo di taglio del nastro in spezzoni, e mezzi di alimentazione dei singoli spezzoni ad una unità o linea d’incarto dei prodotti, costituiti, ad esempio, da gruppi di sigarette. Nelle unità di alimentazione di tipo noto il dispositivo di taglio, generalmente costituito da una coppia di rulli controrotanti muniti di lame, è posto lungo il percorso del nastro continuo in posizione più possibile prossima alla linea d’incarto. Tale posizionamento, a volte difficilmente attuabile a causa di motivi di ingombri e di layout generale di macchina, è preferibile per evitare il trasferimento degli spezzoni lungo percorsi relativamente lunghi. [0002] As is known, units of the type in question comprise means for carrying out a continuous strip of paper material from a reel, a device for cutting the strip into pieces, and means for feeding the individual sections to a unit or line of wrapping of products, consisting, for example, of groups of cigarettes. In known supply units, the cutting device, generally consisting of a pair of counter-rotating rollers provided with blades, is placed along the path of the continuous belt in a position as close as possible to the wrapping line. Such positioning, sometimes difficult to implement due to overall dimensions and general machine layout, is preferable to avoid the transfer of the pieces along relatively long paths.
[0003] È evidente infatti come tale trasferimento comporti l’impiego di mezzi di guida e di controllo estremamente complessi e costosi, al fine di consentire un delicato trattamento degli spezzoni e il loro corretto posizionamento al momento dell’impatto con un rispettivo prodotto diretto alla linea d’incarto. [0003] It is in fact evident that this transfer involves the use of extremely complex and expensive guide and control means, in order to allow a delicate treatment of the pieces and their correct positioning at the moment of impact with a respective product directed to the wrapping line.
[0004] A questo inconveniente si aggiunge il fatto che i dispositivi di taglio del tipo sopra considerato necessitano di frequenti affilature e sostituzioni delle lame. È anche noto l’utilizzo, nelle macchine confezionatrici del tipo in oggetto, di materiali d’incarto di tipo multistrato. [0004] To this drawback is added the fact that the cutting devices of the type considered above require frequent sharpening and replacement of the blades. It is also known to use multilayer wrapping materials in packaging machines of the type in question.
[0005] I materiali di questo tipo, presentanti particolari caratteristiche sia di robustezza, sia estetiche, sia di tenuta, sono composti, ad esempio, da uno strato di materiale cartaceo e da almeno uno strato di materiale termoplastico. [0005] Materials of this type, having particular characteristics both in terms of strength, aesthetics and sealing, are composed, for example, of a layer of paper material and at least one layer of thermoplastic material.
[0006] Scopo della presente invenzione è realizzare un metodo di alimentazione di materiale d’incarto in una macchina confezionatrice di prodotti che sia esente dagli inconvenienti evidenziati con riferimento alla tecnica nota, e conseguenti al forzato posizionamento del dispositivo di taglio, relativamente ingombrante, in prossimità della unità d’incarto. [0006] The object of the present invention is to provide a method of feeding wrapping material in a product packaging machine that is free from the drawbacks highlighted with reference to the prior art, and consequent to the forced positioning of the relatively cumbersome cutting device, in proximity of the wrapping unit.
[0007] Un ulteriore scopo della presente invenzione è quello di realizzare una unità in grado di attuare il suddetto metodo. [0007] A further object of the present invention is to provide a unit capable of implementing the aforementioned method.
[0008] In accordo con l’invenzione vengono realizzati un metodo ed una unità di alimentazione di materiale d’incarto in una macchina confezionatrice di prodotti comprendente le caratteristiche presenti in una o più delle rivendicazioni allegate. La presente invenzione verrà ora descritta con riferimento ai disegni annessi, che illustrano una forma di attuazione non limitativa della presente invenzione, nei quali: <tb>la fig. 1<sep>illustra in vista frontale e schematica una unità di alimentazione di materiale d’incarto secondo la presente invenzione; <tb>la fig. 2<sep>illustra una vista in scala maggiorata ed in sezione un particolare della fig. 1; e <tb>la fig. 3<sep>illustra in vista prospettica il particolare di fig. 2.[0008] In accordance with the invention, a method and a unit for feeding wrapping material are produced in a product packaging machine comprising the features present in one or more of the attached claims. The present invention will now be described with reference to the annexed drawings, which illustrate a non-limiting embodiment of the present invention, in which: fig. 1 shows a frontal and schematic view of a unit for feeding wrapping material according to the present invention; fig. 2 shows a view in enlarged scale and in section a detail of fig. 1; is fig. 3 shows a detail of fig. 2.
[0009] Con riferimento alla figura con 1 è indicata nel suo complesso una macchina confezionatrice di prodotti, ad esempio una macchina impacchettatrice di gruppi di sigarette schematizzati sotto la forma di blocchi parallelepipedi 2. La macchina 1 comprende un basamento 3 definito frontalmente da una parete 4 verticale, sulla quale è montata una unità o dispositivo 5 di alimentazione di materiale d’incarto ad una unità o linea d’incarto 6, alla quale sono alimentati, tramite un convogliatore orizzontale 7, i prodotti 2. [0009] With reference to the figure, 1 indicates as a whole a product packaging machine, for example a packing machine for groups of cigarettes schematized in the form of parallelepiped blocks 2. The machine 1 comprises a base 3 defined frontally by a wall 4, on which is mounted a unit or device 5 for feeding wrapping material to a wrapping unit or line 6, to which the products 2 are fed through a horizontal conveyor 7.
[0010] Fa parte dell’unità 5 di alimentazione un asse 8 trasversale alla parete 4 di supporto di una bobina 9, dalla quale viene svolto un nastro 10 continuo di materiale d’incarto lungo un percorso P definito da una pluralità di rulli di rinvio, indicati da monte a valle, con riferimento ad una freccia F, con 11a, 11b, 1e, e girevoli attorno ad assi paralleli all’asse 8. [0010] Part of the supply unit 5 is an axis 8 transversal to the support wall 4 of a coil 9, from which a continuous strip 10 of wrapping material is unwound along a path P defined by a plurality of return rollers , indicated from upstream to downstream, with reference to an arrow F, with 11a, 11b, 1e, and rotatable about axes parallel to the axis 8.
[0011] In corrispondenza di una posizione 12, interposta fra i rulli di rinvio 11a e 11b, è previsto un dispositivo di taglio parziale del nastro 10 di tipo a raggi laser schematizzato con un blocco 13. [0011] At a position 12, interposed between the deflection rollers 11a and 11b, a device for partial cutting of the strip 10 of a laser beam type is provided, schematized with a block 13.
[0012] In corrispondenza di una posizione 14, disposta a valle del rullo di rinvio Ile lungo un tratto verticale del percorso P, è previsto un dispositivo 15 di strappo per la separazione di singoli spezzoni 16 dal nastro 10, ciascuno dei quali destinato all’avvolgimento di un prodotto 2 nell’unità d’incarto 6. [0012] At a position 14, located downstream of the return roller 11 along a vertical portion of the path P, a tear-off device 15 is provided for the separation of individual sections 16 from the belt 10, each of which is intended for wrapping of a product 2 in the wrapping unit 6.
[0013] Il dispositivo 15 di strappo comprende una prima ed un seconda coppia di rulli controrotanti, rispettivamente indicati con 17 e 18. I rulli 17, 18 di ciascuna coppia sono sostanzialmente tangenti fra loro e la velocità tangenziale dei rulli della seconda coppia 18 è superiore a quella dei rulli della prima coppia 17. Con riferimento in particolare alle fig. 2 e 3, il nastro 10 di materiale d’incarto svolto dalla bobina 9 è di tipo multistrato ed è composto da uno strato 19 di materiale cartaceo e da uno strato 20 di polipropilene, fra i quali è interposto uno strato 21 di polietilene tereftalato. [0013] The tear-off device 15 comprises a first and a second pair of counter-rotating rollers, respectively indicated with 17 and 18. The rollers 17, 18 of each pair are substantially tangent to each other and the tangential speed of the rollers of the second pair 18 is higher than that of the rollers of the first pair 17. With reference in particular to figs. 2 and 3, the web 10 of wrapping material unwound from the reel 9 is of the multilayer type and is composed of a layer 19 of paper material and a layer 20 of polypropylene, between which a layer 21 of polyethylene terephthalate is interposed.
[0014] Il polietilene tereftalato (PET) è costituito da una resina termoplastica particolarmente adatta al contatto con prodotti alimentari, la quale presenta la caratteristica di risultare sostanzialmente insensibile almeno a determinate frequenze dei dispositivi di taglio a raggi laser. [0014] Polyethylene terephthalate (PET) consists of a thermoplastic resin particularly suitable for contact with food products, which has the characteristic of being substantially insensitive at least to certain frequencies of laser beam cutting devices.
[0015] In uso, al passaggio del nastro 10 in corrispondenza della posizione 12 di taglio parziale, il dispositivo 13 a raggi laser effettua, secondo un passo determinato, funzione della lunghezza degli spezzoni 16, una incisione o taglio parziale 22 trasversale sullo strato 19 di materiale cartaceo, fino allo strato di PET. Tali incisioni 22 definiscono delle linee di indebolimento che consentono il successivo trascinamento del nastro 10 attraverso un tratto PI del percorso P, fino alla posizione 14, in corrispondenza della quale il dispositivo 15 di strappo effettua la separazione del nastro 10 stesso nei singoli spezzoni 16. [0015] In use, when the tape 10 passes in correspondence with the partial cutting position 12, the laser beam device 13 performs, according to a determined step, a function of the length of the pieces 16, a cross-sectional cut or cut 22 on the layer 19 of paper material, up to the PET layer. These incisions 22 define weakening lines which allow the subsequent conveyance of the strip 10 through a portion PI of the path P, up to the position 14, at which the tear-off device 15 separates the strip 10 itself into the individual sections 16.
[0016] È evidente che tale metodo e la relativa unità 5 di alimentazione permettono, a differenza di quanto visto con riferimento alla tecnica nota, di posizionare il dispositivo di taglio parziale 13 del nastro 10 di materiale d’incarto ad una qualsiasi conveniente distanza dall’unità d’incarto e nel contempo di alimentare correttamente i singoli spezzoni 16 alla linea d’incarto 6 senza necessità di impiego di complessi sistemi di guida e di controllo. [0016] It is evident that this method and the relative supply unit 5 allow, unlike what has been seen with reference to the prior art, to position the partial cutting device 13 of the tape 10 of wrapping material at any convenient distance from the the wrapping unit and at the same time to correctly feed the individual sections 16 to the wrapping line 6 without requiring the use of complex guidance and control systems.
