Definitions

  • the present invention relates to a labelling machine for applying labels onto containers adapted to contain, i.e. to be filled with, a pourable product, preferably a pourable food product.
  • Labelling machines are known, which are commonly used to prepare, transport and apply labels onto articles, such as bottles, containers, or the like destined to be filled with a pourable product, in particular a pourable food product.
  • glued labels i.e. portions of a labelling material that are cut at appropriate lengths from a web of labelling material initially wound around one or more reels, then sprinkled with glue and eventually applied onto the respective containers.
  • Labels of the tubular kind known as "sleeve labels” and obtained starting from a web of heat-shrinking film wound around one or more storage reels are also known; the sleeve labels are applied with a certain clearance on the respective containers and then heated in an oven to obtain their shrinking and perfect adhesion to the lateral surfaces of the containers themselves. These types of labels do not require the use of glue.
  • a known labelling machine typically comprises:
  • a labelling module typically comprises:
  • the carousel comprises a plurality of support plates, peripherally carried by the carousel itself in respective fixed positions and each configured to support one container to be labelled at a time, and to move it along the labelling path.
  • the carousel also comprises a plurality of gripping heads, each arranged in a respective fixed position above one respective support plate and configured to grip the top part of the neck portion of the container to be labelled in order to define a firm support for the same during labelling, thereby counteracting the forces exerted on the container during labelling.
  • the labelling machines of the above-mentioned type are usually part of an apparatus for packaging the pourable product, which typically comprises several units for carrying out respective operations within the packaging process, namely:
  • all these units comprise respective carousels to convey the containers undergoing the relative operations along respective operative paths (the labelling path, a filling path, a capping path, a forming path).
  • the Applicant has observed that the known packaging apparatuses are prone to further improvement, in particular as to improve their reliability and flexibility, to simplify their architecture, and to reduce the total number of their components and their overall size.
  • number 1 indicates as a whole a labelling machine for applying labels 2 onto containers 3 adapted to contain, i.e. to be filled with, a pourable product, preferably a pourable food product, such as water, wine, beer, juice, soft drinks, milk, yogurt, or the like.
  • a pourable product preferably a pourable food product, such as water, wine, beer, juice, soft drinks, milk, yogurt, or the like.
  • labels 2 are obtained starting from a web 2a of labelling material which is sequentially cut, in a known manner not described in detail, at predetermined intervals so as to produce labels 2 of equal length, which are then sprinkled with glue and eventually applied onto the respective containers 3.
  • the web 2a is self-adhesive and the glue is not needed.
  • the labels 2 are of the type known as "sleeve labels" and the glue is not needed.
  • Labelling machine 1 comprises:
  • the labelling module 5 comprises a transfer drum, in particular a vacuum drum 6 of the known type, configured to receive the labels 2 previously cut from the web 2a and to transfer the labels 2 to the labelling station S, at which they are applied onto the respective containers 3.
  • a transfer drum in particular a vacuum drum 6 of the known type, configured to receive the labels 2 previously cut from the web 2a and to transfer the labels 2 to the labelling station S, at which they are applied onto the respective containers 3.
  • the conveyor 4 comprises:
  • planar motor 10 comprises a plurality of electrically and individually excitable solenoids (not shown), preferably embedded in work platform 7, and apt to be supplied, in use, with electric current for generating an electromagnetic field.
  • each cart 8 is equipped with a permanent magnet configured to magnetically interact with the solenoids, thereby producing the levitating movement of the cart 8 relative to the work platform 7.
  • work platform 7 is defined by a flat table onto which carts 8 are distributed and relative to which carts 8 levitate by means of planar motor 10.
  • planar motor 10 is arranged, particularly embedded, in work platform 7.
  • each cart 8 comprises ( Figure 2 ):
  • the labelling path L can be shorter and extremely flexible and variable, since containers 3 are not to be carried in respective positions which are fixed with respect to the carousel.
  • the mechanical configuration of labelling machine 1 is less complex.
  • the labeling machine 1 according to the invention has a simplified architecture, an improved flexibility and reliability, a reduced number of components, and a reduced size.
  • base portion 11 carries the above-mentioned permanent magnet.
  • each rotary member is defined by a rotary plate 12.
  • each rotary plate 12 carries a sleeve 13 open on one (upper) side to define a seat for receiving, holding and supporting the bottom portion of at least one container 3 at a time. In this way, each container 3 is firmly supported and the risk of fall or misalignment is at least limited, preferably avoided.
  • Each container 3 has a longitudinal axis.
  • Each rotary plate 12, and particularly each sleeve 13, is configured to receive the container 3 with its longitudinal axis orthogonal to the rotary plate 12 itself and to the work platform 7.

  • permanent magnets are embedded/arranged in work platform 7, while each cart 8 is equipped with at least one individually-excitable solenoid.
  • each rotary plate 12 is rotatable relative to the base portion 11 by means of interaction with the labelling module 5, and preferably by: mechanical contact of the rotary plate 12 itself with a component of the labelling module 5 (e.g. with a portion of the vacuum drum 6); and/or by mechanical contact of the sleeve 13 with a component of the labelling module 5 (e.g. with a portion of the vacuum drum 6); and/or by magnetic or electromagnetic interaction of the rotary plate 12 itself and/or of the sleeve 13 with a component of the labelling module 5 (e.g. with a portion of the vacuum drum 6).
  • the component of the labelling module 5 can be for example a toothed surface or a magnetic surface.
  • labelling machine 1 is configured so that the rotary plate 12 of each cart 8 rotates on itself at least while the cart 8 is moving through the labelling station S.
  • labelling machine 1 comprises a plurality of gripping heads 14 each configured to grip and hold the top portion, i.e. the neck or mouth portion, of at least one container 3 at a time at least during the label application thereon at labelling station S, i.e. when container 3 passes through (is conveyed through) labelling station S.
  • labelling machine 1 comprises an auxiliary conveyor 15 for cyclically conveying gripping heads 14 at labelling station S.
  • the auxiliary conveyor is configured so that each gripping head 14 is cyclically conveyed at labelling station S kinematically independently from the other gripping heads 14.
  • the machine 1 is configured so that each gripping head 14 is cyclically conveyed at labelling station S kinematically independently from the carts 8.
  • auxiliary conveyor 15 is configured so that, for each container 3 conveyed by one respective cart 8 through labelling station S, one gripping head 14 engages the top portion of such container 3 while the gripping head 14 is moving through labelling station S, so as to support and hold the container 3 against the one respective cart 8.
  • each gripping head 14 has to follow the respective member supporting the container only at the labelling station. Therefore, the number of the gripping heads 14 can be reduced. The above results in a labelling machine 1 with an increased flexibility, reliability, with a reduced number of components, and therefore with reduced costs.
  • labelling machine 1 has a more flexible configuration.
  • auxiliary conveyor 15 comprises:
  • wall 17 is arranged vertically.
  • the size, and particularly the horizontal extension of the labelling machine 1 can be reduced, allowing a more efficient coupling of the labelling machine with other machines.
