Definitions

  • the present invention relates to a roller for transferring labels of the aspirating kind, provided with at least a notch obtained on a lateral surface of the roller and shaped in such a way as to collect glue residues, in particular for labelling machines in which the labels are obtained from a reeled film.
  • the present invention further relates to a method for collecting glue or adhesive substances in a roller for transferring labels of the aspirating type, in particular for labelling machines.
  • rollers for transferring labels are employed in labelling machines provided with a device for unwinding the reel, necessary to route a film of labels towards a cutting device, which forms the label to be glued on a container.
  • the label thus formed is always rectangular or square shaped and has two vertical and parallel edges.
  • the transfer roller rotating at a pre-set velocity about an axis, picks up the label and transfers it in correspondence with gluing means and subsequently on the container to be labelled.
  • the gluing means lay a first strip of glue along a rear face of one of the vertical edges of the label and subsequently lay a second strip of glue on the other vertical edge, which is to be superposed and glued on to the first edge.
  • the containers to be labelled are brought in contact with the roller for transferring the label by means of a linear or rotary conveyor commonly known as carrousel.
  • the transfer roller is provided with a group of pincers so shaped as to keep the label adhering to the lateral surface of the roller itself.
  • a second technique in the prior art provides for obtaining, inside a roller without pincers, a plurality of cavities communicating with the lateral surface of the roller, typically by means of a series of through holes. Subsequently, through said cavities, an aspiration of variable and controlled intensity is effected in such a way that the labels remain adhering to the lateral surface of the roller during their transfer from the cutting device to the container.
  • the document US-4 416 714 discloses such a device in accordance with the preamble of appended claim 1.
  • Such transfer rollers are also provided with a plurality of notches obtained on the lateral surface to collect glue residues which otherwise would be deposited on the holes needed to effect the aspirating action, thereby compromising the operation of the machine. Such residues are caused by the contact between the label and the gluing means.
  • transfer rollers provided with a group of pincers are complex to build, because they require a system of appropriately dimensioned cams to open and close the pincers during the rotation of the roller.
  • a labelling machine equipped with such a roller is not suitable for high productivity bottling plants, because of the reduced velocities of rotation of the roller.
  • the main drawback is represented by the fact that the glue residues that are deposited in the notches must be frequently removed to prevent them from fouling the surface of the roller tasked with collecting the labels. To clean the roller, it is necessary to stop the labelling machine or the surfaces tasked with correctly positioning the label and consequently interrupt production.
  • the aim of the present invention is to eliminate the aforesaid drawbacks, making available a roller for transferring labels of the aspirating type and a method for collecting adhesive substances, which are able to expand the time interval between two successive cleaning operations.
  • Another aim of the present invention is to propose a roller for transferring labels of the aspirating type and a method for collecting adhesive substances that are able to reduce the speed whereby any glue deposits are formed.
  • a further aim of the present invention is to make available a roller for transferring label of the aspirating type that is easy to construct and can be used on the labelling machines currently on the market.
  • roller for transferring labels is globally indicated with the number 1.
  • the roller 1 is provided with a plurality of notches 2 obtained on a lateral surface 3 of the roller itself and shaped in such a way as to collect any glue residues caused by the contact between the label and the gluing means.
  • the roller 1 is originally provided with a plurality of openings 4 obtained on portions 3a of the lateral surface 3 positioned internally to each notch 2, in order to place the latter in communication with at least an aspiration conduit operatively connected to the roller itself.
  • said openings 4 are preferably a plurality of through holes.
  • the possibility is provided of obtaining said openings 4 by means of a plurality of slots, appropriately dimensioned to aspirate the glue residues.
  • the notches 2 are positioned along the lateral surface 3 at a pre-set mutual distance along the lateral surface and they are preferably longitudinal grooves open at the ends and with length substantially coinciding with the height of the roller 1.
  • the possibility is provided of obtaining said notches 2 by means of longitudinal grooves with length substantially coinciding with the height of the roller and closed at the ends by plate-like elements, in order to enhance the effectiveness of the aerodynamic field generated by the aspiration of the glue residues.
  • conduit for aspirating the glue residues is operatively connected to aspirating means (not shown in the figure) which also generate the aspirating action required to maintain the labels adhering to the lateral surface 3 of the roller 1.
  • the conduit for aspirating the glue residues is preferably distinct from a conduit necessary to perform the aspirating action on the labels.
  • the roller 1 further comprises means for adjusting the aspiration of the glue and/or of the labels.
  • said adjustment means (not shown in the figure) comprise a plurality of valves obtained by means of a holed plate interposed between the roller and the aspiration conduits and provided with a series of through cavities positioned according to an appropriate pattern to define a so-called valve plate.
  • each notch 2 In proximity to each notch 2 is present a corresponding shoe 5, inserted in sliding fashion in an appropriate seat located on the lateral surface 3 of the roller 1. On the shoe 5 is set down one of the two edges of each label, whereon the glue is laid by means of rubbing against the gluing means. Said rubbing is made possible by the fact that each shoe 5 projects relative to the lateral surface 3 of the transfer roller 1.
  • the glue laid on the labels interacts aerodynamically with the air surrounding the roller, forming drops of variable diameter that are deposited inside the notches 2.
  • the aspirating means are able to such said glue drops back in, reducing the speed of formation of such deposits as would require maintenance operations.
  • the method for collecting glue or adhesive substances, of the present invention comprises the stage of aspiration of the glue or adhesive substances that are deposited inside at least a notch obtained on a lateral surface of a roller and so shaped as to collect any residues of glue or other adhesive substances that are formed during the operation of the roller.
  • the invention achieves important advantages.
  • a roller according to the present invention allows to expand the time interval between two subsequent maintenance operations.
  • the presence of the openings together with the aspirating means considerably reduces the speed of formation of such glue deposits as would require to stop the machine.
  • a method of collection according to the invention can also be employed on existing rollers, since no substantial modifications to the roller are necessary, but only the execution of a plurality of openings inside the notches and the aspirating action by means of dedicated conduits connected thereto are required.
