Definitions

  • the invention relates to a group for collecting labels from a magazine, in labelling machines.
  • DE-A-1 936 839 describes such a group corresponding to the preamble of claim 1.
  • Such groups have a rotating carousel on which label collecting organs, known as blades, are mounted.
  • the blades are provided with a curved active surface and contact with a glueing group whereat their active surfaces are coated with a thin layer of glue, before passing on to the label magazine.
  • the curved active surface of each blade drags (without slippage) on a label, and thanks to the layer of glue picks up said label.
  • the active surface of the label is at least equal to the size of the label.
  • the length referred to above is of about 180-220 mm, with the standard size of the carousel diameter being of about 400 mm so that the whole label-collecting group can be of a contained size in order to limit the mass of the entire labelling machine. If larger labels are to be used, the collecting group has to be increased in size as well, which obviously leads to an economic/practical drawback, namely that the rest of the labelling machine has to be increased in size and therefore will cost more to make, transport, and so on.
  • the principal aim of the present invention is to obviate the above-mentioned drawbacks by providing a label-collecting group of standard dimensions but capable of collecting longer than standard labels, and in particular much longer labels than the lengths of traditional blade active surfaces have up to now permitted.
  • the label-collecting group for labelling machines constituted by a rotating carousel peripherally bearing at least one blade to collect the labels from the magazine, after first passing through the glueing group.
  • the blade also rotates partially about its own support shaft, said shaft being equipped with a gearing mechanism associated to a cogged sector partially raotating in two opposite directions about a pivot.
  • the blade is solid, by means of its support shaft, to a mobile body arranged peripherally of the carousel, a curved element also being fixed to the mobile body, said curved element having a similar curvature to the blade and being arraged on the trajectory of the blade in the ratation direction of the carousel.
  • the curved element receives the glue when it passes through the glueing group and collects the part of each single label that extends further than the size of the active curved surface of the blade.
  • the invention comprises at least one skate wheel, slideable in a shaped track, to enable the mobile body to move externalwise with respect to the carousel such that the blade can come into contact with the label, and remove it from the magazine.
  • 1 denotes a conveyor, (not illustrated for the sake of simplicity) feeding bottles, jars or other containers to a rotary structure 2 by means of a transfer wheel 3.
  • the labels are applied on the bottles on the rotary structure 2 by a drum 4, after which the bottles are removed by a further transfer wheel 5 and placed on a conveyor 6.
  • arrows indicate the movement directiob of the bottles.
  • 7 denotes the label collecting group of the invention, while 8 indicates the glueing group and 9 the label magazine: apart from the label collecting group, the other organs are of known type and will not be further described in the following description.
  • the label collecting group 7 comprises a rotary carousel 11 bearing blades 12 at its periphery, each of which blades 12 is provided with a curved active surface 13 removing the labels singly from the magazine 9 after having first passed through the glueing group 8.
  • the carousel 11 comprises a cover (denoted in figure 8 by 11) driven by a shaft 14 motorised by a gear couple 15 and 16, gear 16 being keyed on a shaft 17.
  • Each blade 12 rotates partially about its own support shaft 18 on which a further gear 19 is keyed, which gear 19 is motorised through an idle gear 20, another gear 21, and a cogged sector 22 partially rotatable in two directions about a pivot 23 fixed to the carousel 11.
  • the cogged sector 22 rotates partially in two directions due to the fact that the cogged sector 22 is provided with a first skate 24 slidably inserted in a first track 25.
  • the track 25 is basically circular and made in the fixed base 26 of the carousel 11.
  • the curvature of the first track 25 deviates from being circular, such that the tracks 25 reaches further internalwise of the fixed base 26 than before, by an extend denoted by L1.
  • This change in trajectory causes a displacement of the skate 24 in a radial centripetal direction with respect to the fixed base 26, which deviation determines a partial rotation of the cogged sector 22 about the pivot 23, with a consequent rotation of the blade 12 about the shaft 18.
  • each blade 12 is solid to a mobile body 27 of approximately trapezoid shape, to which the shafts of the gears 19, 20 and 21 are fixed.
  • a curved element 28 is rigidly fixed to the mobile body 27 and has an active surface 29 provided with a similar curvature to that of the blade 12 surface 13, and is arranged on the circular trajectory of the blade 12 in the rotation direction of the carousel 11.
  • the curved element 28 receives the glue when it passes at the glueing group 8 and then receives, on its surface 29 (by now spread with glue), the part of every label 10 collected by the blade 12 which overlaps the blade 12 active surface 13.
  • This sequence is illustrated in figures 6 and 7.
  • the mobile body 27 displaces radially centrifugally with respect to the carousel 11. This movement is made possible by the existence of a second skate 30, solid to the body 27, which is slidably inserted in a second circular track 31 made in the fixed base 26.
  • the second track 31 is not perfectly circular but deviates such as to create a displaced tract L2 externalwise of the fixed base 26. This change in trajectory induces a diplacement in the second skate 30 trajectory in a radial centrifugal direction (with respect to the base 26) and thus also of the body 27.
  • an idle roller 32 (see figures 4 and 7) is installed, which presses the label 10 against the surface 29 of the curved element 28, enabling it to be correctly positioned.
