Definitions

  • the present invention relates to a method for parting labels from a web of labelling material, in particular labels configured to be applied to articles adapted to contain a pourable product, preferably a pourable food product.
  • Labelling machines are known, configured to process a labelling material in an automated labelling process and commonly used for preparing, transporting and applying labels to articles, in particular bottles, containers, jars, flacons or the like, made of glass, plastic or metal, adapted to contain a pourable product, preferably a pourable food product.
  • said web is cut into equal sized portions, to which the glue is applied.
  • Glue is usually applied by gluing means, for example rollers, spray systems, injection systems, or the like.
  • the labels thus obtained are then transferred and glued onto the outer side surface of the respective articles.
  • a labelling module of the known type comprises:
  • the labelling module comprises, furthermore, a label parting device configured to part, in particular to sequentially part, the labels from the respective web of labelling material which is unwound, in use, from the relative reel.
  • the parting device usually comprises a blade (or a cutting tool) configured to cut the web at its predetermined cutting portions.
  • the parting devices commonly used in labelling modules of the type described above, are of the rotary type and comprise:
  • the web is interposed, during the cutting, between the first and the second rotary elements.
  • the carousel, the transfer device, the gluing roller, the unwinding rollers and the rollers of the parting device are perfectly synchronised, so as to correctly carry out the entire labelling process.
  • the parting device can be of the reciprocating motion type, namely, having a fixed counter-blade surface and a mobile blade with reciprocating motion that goes into abutment against the counter-blade surface to sequentially cut the web.
  • a weakening, in particular perforation, device is known instead of the blade and the counter-blade surface, in order to create a weakening in predetermined weakening areas of the web, which substitute, in this case, the above-mentioned cutting portions.
  • the weakening device is configured to carry out the perforations on each predetermined weakening area of the web, along a direction substantially orthogonal to the longitudinal direction of the web.
  • the web is sequentially pulled so as to cause breakage of the various weakening portions and the parting of each label from the web itself at the relative perforations.
  • the aim of the present invention is to achieve a method for parting labels from a web of labelling material having increased reliability and limited cost, and which enables to meet at least some of the needs specified above in a simple and economic manner.
  • this aim is achieved by a method to part labels from a web of material to be labelled as claimed in claim 1.
  • 1 designates, as a whole, a labelling machine configured to process a labelling material in an automated labelling process.
  • the machine 1 is configured to apply labels 2, obtained from a web 3 of labelling material, to articles 4 designed to (adapted to) contain a pourable product, preferably of the food type.
  • the articles 4 are defined by bottles, flacons, cans, jars, small jars, or the like, each of which is adapted to receive, during the above-mentioned labelling process, a respective label 2 on the relative outer side surface.
  • the labels 2 are of the type known as "glued labels", namely, labels 2 obtained starting from the web 3, which is initially wound around one or more reels 5 (only one of which is shown in figure 1 ) and is subsequently parted into equal sized portions defining the labels 2.
  • the labels 2 thus obtained are then transferred and applied, by means of glue, onto the outer side surface of the respective articles 4, according to a mode that will be described in the following.
  • the machine 1 basically comprises:
  • the machine 1 comprises two or more labelling modules 7 arranged peripherally with respect to the carousel 6 and configured to apply respective pluralities of labels 2 to relative articles 4 at respective application stations A.
  • the labelling module 7 comprises:
  • the transfer device is configured, furthermore, to feed labels 2, obtained from the web 3 according to a mode that will be described in the following, along the feeding path Q and feed said labels 2 to the carousel 6 at the application station A, so that they can be applied to respective articles 4.
  • the transfer device is defined by a conveyor 12 arranged peripherally to a carousel 6, at the application station A, and comprising:
  • the carts 14 are slidable along the track 13 independently from one another.
  • the conveyor 12 comprises an electromagnetic linear motor, of the known type, configured to enable the independent control of the carts 14 along the track 13, according to a known mode and not described in detail.
  • the track 13 is provided with electrically excitable elements and generators with an electromagnetic field, for example a solenoidal coil, and each cart 14 is provided with a permanent magnet (not illustrated).
  • Each permanent magnet is configured to be magnetically coupled to the above-mentioned coils, according to a known mode typical of linear motors.
  • each cart 14 comprises a support portion 15 configured to cooperate in contact with the web 3.
  • each support portion 15 comprises a side surface 16 configured to receive, hold and advance the web 3 along the feeding path Q, and to hold, advance and release the relative label 2 obtained from the web 3 according to the mode that will be described in the following.
  • each side surface 16 is provided with a series of holes 17 distributed on the side surface 16 itself and fluidically connected to a vacuum source known and not described in detail.
  • the vacuum source creates a negative pressure, and therefore a suction (or vacuum), at the holes 17, which allows to suck-up and hold the web 3.
  • each cart 14 holds, in use, a relative portion of the web 3, having a size substantially corresponding to the size of the side surface 16, by means of suction through the relative holes 17.
  • each cart 14 is configured to hold a relative portion of the web 3 that will constitute an individual label 2.
  • each cart 14 has respective opposite side end portions configured to respectively hold portions of the web 3 that will constitute the front edge and the rear edge of each label 2, according to the feeding direction of the label 2 along the feeding path Q.
  • the feeding path Q is parallel to the advancing path R at least for the segment in which the web 3 is conveyed by means of the conveyor 12.
  • the labelling module 7 comprises, furthermore, a weakening device 18 arranged peripherally to the conveyor 12, in particular peripherally to the track 13 at a weakening station D, and configured to sequentially weaken the web 3 at predetermined weakening areas 19 of the web 3 itself.
  • the weakening device 18 comprises a blade 20, in particular a serrated blade, configured to move with reciprocating motion transversally relative to the feeding path Q, and therefore transversally relative to the web 3, and to sequentially cooperate in contact with the web 3 at the weakening station D.
  • the blade 20 is configured to sequentially perforate each weakening area 19 so as to obtain a series of perforations 21, preferably aligned on the web 3 along a direction transverse to the web 3 itself.
  • weakened portions are obtained, which pass through the web 3 transversally from one side to the other, substantially corresponding to the weakening areas 19 and configured to break under tension.
  • the labelling module 7 comprises, furthermore, a gluing device, in particular a gluing roller 22, arranged peripherally to the conveyor 12, in particular peripherally to the track 13 at a gluing station G, and configured to sequentially spread glue onto the web 3 at predetermined gluing areas 23 of the web 3 itself.
  • a gluing device in particular a gluing roller 22, arranged peripherally to the conveyor 12, in particular peripherally to the track 13 at a gluing station G, and configured to sequentially spread glue onto the web 3 at predetermined gluing areas 23 of the web 3 itself.
  • each gluing area 23 has a substantially rectangular shape, extends transversally along the entire width of the web 3 and comprises, within its own delimiting perimeter, the respective weakening area 19.
  • each weakening area 19 is included in the corresponding gluing area 23.
  • each weakening area 19 is arranged, in use, between two adjacent carts 14, as shown in particular in figure 2 .
  • the relative weakening area 19 is comprised between the above-mentioned rear edge of the label 2 which leads (leading label) and the above-mentioned front edge of the label 2 that follows (trailing label) .
  • each weakening area 19 defines a transition area interposed between two consecutive labels 2.
  • each weakening area 19 is not supported at the rear by any side surface 16, but is instead "hanging" between the two side surfaces 16 of the pair of adjacent carts 14 and is kept tensioned by the relative movement of said carts 14, so as to be able to be effectively perforated by the blade 20 at the weakening station D.
  • the gluing station G is arranged downstream of the weakening station D, according to the advancing direction of the carts 14 along the advancing path R and according to the advancing direction of the web 3 along the feeding path Q.
  • the gluing roller 22 is arranged downstream of the weakening device 18, namely the blade 20, relative to the above-mentioned advancing directions.
  • the web 3 is firstly weakened and then spread with glue.
  • the above-described configuration is particularly advantageous in the case where a mismatch of the various components of the labelling module 7 occurs, due to which, the gluing areas 23 are not perfectly arranged in the predetermined nominal position at the gluing station G, since the blade 20 has the web 3 already weakened at the moment of the application of the glue.
  • the web 3 is configured to be sequentially put under tension, after the application of the glue by means of the roller 22, for parting successive individual labels 2 at the respective weakening areas 19.
  • the carts 14 are controllable to be distanced away from one other along said advancing path R at a parting station S arranged downstream of the gluing station G, according to the above-mentioned advancing directions.
  • the cart 14 that leads (leading cart) is controllable, in particular controlled, in use, to move away from the cart 14 that follows (trailing cart), along the advancing path R.
  • Such label 2 is held by the relative cart 14 which is now distanced and is conveyed up to the application station A, at which it is applied to the respective article 4 simultaneously conveyed by the carousel 6.
  • each gluing area 23 splits, at the parting station S, into:
  • the blade 20 is defined by a serrated blade, in particular a serrated blade extending along a direction transverse to the web 3, preferably parallel to the axis X of the carousel 6, and having a plurality of teeth 24 with a triangular profile and arranged in a row along the above-mentioned transverse direction.
  • the serrated blade 20 according to the present invention can comprise all or any combination of said constructive parameters.
  • the weakening device 18 comprises a serrated blade 20' including sets of teeth 27, each set formed by a plurality of teeth 24 of the type described above.
  • the sets of teeth 27 have a substantially triangular profile and are arranged in a row along the above-mentioned transverse direction.
  • the above-mentioned ideal plane is parallel to the transverse direction.
  • the operation of the labelling machine 1 according to the present invention will be described in the following, with particular reference to a pair of adjacent carts 14, to a single weakening area 19 and to a single gluing area 23, in a starting condition in which the weakening area 19 is at the weakening station D.
  • the blade 20 is controlled so as to perforate, and thus weaken, the web 3 at the weakening area 19.
  • the roller 22 spreads the glue at the gluing area 23, including the entire weakening area 19, of the web 3, at the gluing station G.
  • the cart 14 that leads is controlled to move away from the cart 14 that follows, so as to put the web 3 under tension and cause the breakage of the weakening area 19 and the parting of the label 2, at the parting station S.
  • the label 2 thus obtained is then fed from the cart 14 that leads, along the feeding path Q and up to the application station A.
  • 1' designates, as a whole, a labelling machine configured to apply labels 2 to articles 4 designed to contain a pourable product made according to an alternative embodiment of the present invention.
  • the machine 1' differs from the machine 1 due to the fact that the web 3 is sequentially put under tension by means of a rotation of the articles 4 on themselves, i.e. about their own axes.
  • the web 3, after having been weakened and spread with glue, is conveyed, still as whole web, in use, up to the application station A.
  • Such article 4 is, therefore, controlled to carry out a rotation on itself around its own axis, so as to favour the application of the web 3 on its side surface.
  • the labelling module 7 of the machine 1' comprises a transfer device defined by a vacuum drum 12', of a known type and not described in detail, arranged peripherally to the carousel 6, at the application station A, and configured to support the web 3 and to advance it along the feeding path G.
  • a transfer device defined by a vacuum drum 12', of a known type and not described in detail, arranged peripherally to the carousel 6, at the application station A, and configured to support the web 3 and to advance it along the feeding path G.
  • the transfer device is defined by the conveyor 12 described above.
  • 1'' designates, as a whole, a labelling machine, configured to apply labels 2 to articles 4 designed to contain a pourable product, made according to an alternative embodiment of the present invention.
  • the machine 1'' differs from the machine 1 due to the fact that it comprises a breakage assist device 30, arranged downstream of the gluing station G along the feeding path Q and configured to sequentially stress each weakening area 19 so as to cause a breakage of the web 3 at each stressed weakening area 19.
  • a breakage assist device 30 arranged downstream of the gluing station G along the feeding path Q and configured to sequentially stress each weakening area 19 so as to cause a breakage of the web 3 at each stressed weakening area 19.
  • the device 30 is a presser configured to sequentially apply a pressure to the web 3 at the parting station S, so as to cause the breakage of the weakening areas 19 of the web 3, thus obtaining respective labels 2.
  • the device 30 applies a pneumatic stress to the web 3 (for example, compressed air).
  • the device 30 applies a mechanical stress to the web 3 (by means, for example, of a cutting tool or an anvil or an ultrasound device).
  • the labels 2 are applied to the articles 4, for example by means of rotation of the same as described above for the machine 1'.
  • the above described configuration enables preventing residues of glue from contaminating the blade 20.
  • the above-described configuration is particularly advantageous in the case where a mismatch of the various components of the labelling module 7 occurs, due to which the gluing areas 23 are not perfectly arranged in the predetermined nominal position at the gluing station G, since the blade 20 already has the web 3 already weakened at the moment of the application of the glue.
