Definitions

  • the vacuum drum can be ideally divided into a plurality of retaining sectors, each of which is angularly delimited by a respective said pair of frontrear pads.
  • FIG. 1 is a schematic top view of a labelling module produced according to the present invention.
  • FIGS. 4a and 4b are schematic top views, on an enlarged scale and with parts removed for clarity, of part of a labelling module produced in accordance with a further embodiment of the present invention.
  • the blade 13 cuts the web 4 to cyclically separate the free end portion 4a from the web 4.
  • the transfer device comprises a vacuum drum 11.
  • the vacuum drum 11 is rotatable about an axis of rotation X, preferably parallel to the axis of the cutting roller 12.
  • the vacuum drum 11 is configured to receive the previously cut labels 2, to retain them by means of suction and, after a rotation by a determined angle around the axis X, to release these labels 2 to the application station A, so that they are applied onto the respective containers 3 advanced by the carousel 6.
  • the vacuum drum 11 has a substantially cylindrical or toroidal configurations and is mounted, so as to rotate with respect to the axis X, on a fixed frame (not illustrated) of the module 1, and in particular on a fixed distributor member (not illustrated) of the module 1.
  • the stationary distributor member has first passages for the air (not illustrated), which are connected to the vacuum source; the vacuum drum 11 is, in turn, provided with second passages for the air (not illustrated), which are configured to communicate with the first passages for the air in determined angular positions of the drum 11 while it rotates about its axis X, and which end in a plurality of holes 14 ( Figure 3) for the vacuum.
  • the holes 14 for the vacuum are formed through an outer lateral surface 11a of the drum 11 to receive the labels 2.
  • An intermediate section 15c ( Figure 3) is angularly interposed between the pads 15a and 15b, for each said pair.
  • each pair aided by the relative intermediate section 15c, retains (by means of the vacuum) one label 2 at a time so as to determine its transfer.
  • a label 2 when retained by the drum 11 it will typically have the leading end 2a arranged on a front pad 15a, the trailing end 2b arranged on a rear pad 15b, and the remaining intermediate part arranged on an intermediate section 15c comprised between the two pads.
  • each label 2 coincides, cyclically, with the free end portion 4a of the web 4.
  • each front pad 15a is cyclically extractable radially from the surface 11a towards the cutting roller 12 to grip the free end portion 4a.
  • each front pad 15a is extractable towards the cutting roller 12 to pick up, from the outer lateral surface 12a of the cutting roller 12, the free end portion 4a/the respective leading end 2a, and determine the progressive detachment of the label 2 from the outer lateral surface 12a. More precisely, each front pad 15a grips the leading end 2a of the respective label 2 before the relative cutting by the blade 13 takes place, i.e., when the label is still attached to the web 4.
  • the pads 15a, 15b are provided with holes 14.
  • the front pad 15a is extractable for gripping the leading end 2a by means of vacuum applied through the holes 14.
  • At least the front pad 15a of each pair is made of a soft elastomeric material, for example rubber.
  • the rear pad 15b is preferably made of a soft elastomeric material, for example rubber.
  • the front pad 15a (and the rear pad 15b, in the case where it is also extractable) is movable between:
  • the module 1 comprises actuator means for controlling the movement of the front pad 15a between the operative position and the rest position.
  • the actuator means comprise:
  • cam follower 17 carried by the front pad 15a and configured to cooperate with the cam 16 for controlling the movement of the front pad 15a between the operative position and the rest position.
  • the cam 16 is mounted centrally within the drum 11 so as to be coaxial to the axis X.
  • the drum 11 has a substantially toroidal shape or ring shape.
  • the cam 16 comprises a main portion 16a and an operative portion 16b, which protrudes radially from the main portion 16a.
  • Each cam follower 17 is stably coupled to the respective front pad 15a.
  • the drum 11 conveys in rotation the pads 15a (and 15b) about the axis X.
  • each cam follower 17 cooperates in contact with the cam 16, by cyclically cooperating with the operative portion 16b.
  • the cam follower 17 is pushed radially towards the outside, determining the movement of the front pad 15a between the operative position and the rest position.
  • the operative portion 16b extends towards the pick-up station R.
  • the actuator means comprise a pneumatic or electric or piezoelectric actuator. In this manner, the control of the pads 15a is more precise and the wear is reduced, since the use of the cam followers 17 which continuously slide on the cam 16 is avoided.
  • the first magnetic element 18 is defined by a first magnet 18 incorporated in the pad 15a, and the second magnetic element 19 defines part of the surface 12a.
  • the second magnetic element 19 comprises, in operative succession:
  • This configuration of the actuator means allows to control each front pad 15a by means of a clean system, which is particularly advantageous in the case of packaging pourable products of the foodstuff type. Furthermore, the maintenance interventions can be further reduced or, however, have a reduced impact on the overall costs, given the simplicity of the components involved.
  • the label 2 is transferred from the drum 11 to the application station A and applied onto a relative container 3.
  • the operation is cyclically repeated for each label 2 and for each pair of pads 15a, 15b.
