Definitions

  • the present invention relates to a unit for applying opening devices to packages of pourable food products.
  • pourable food products such as fruit juice, UHT (ultra-high-temperature-treated) milk, wine, tomato sauce, etc.
  • UHT ultra-high-temperature-treated milk
  • wine tomato sauce
  • etc. are sold in packages made of sterilized packaging material.
  • a typical example of this type of package is the parallelepiped-shaped package for liquid or pourable food products known as Tetra Brik Aseptic (registered trademark), which is made by folding and sealing a web of laminated packaging material.
  • the packaging material has a multilayer structure comprising a layer of fibrous material, e.g. paper, covered on both sides with layers of heat-seal plastic material, e.g.
  • polyethylene and, in the case of aseptic packages for long-storage products, such as UHT milk, also comprises a layer of oxygen-barrier material, defined, for example, by aluminium foil, which is superimposed on a layer of heat-seal plastic material, and is in turn covered with another layer of heat-seal plastic material eventually defining the inner face of the package contacting the food product.
  • a layer of oxygen-barrier material defined, for example, by aluminium foil
  • such packages are produced on fully automatic packaging machines, on which a continuous tube is formed from the web-fed packaging material; the web of packaging material is sterilized on the packaging machine itself, e.g. by applying a chemical sterilizing agent, such as a hydrogen peroxide solution, which, once sterilization is completed, is removed, e.g. vapourized by heating, from the surfaces of the packaging material; and the web of packaging material so sterilized is kept in a closed, sterile environment, and is folded and sealed longitudinally to form a vertical tube.
  • a chemical sterilizing agent such as a hydrogen peroxide solution
  • the tube is filled with the sterilized or sterile-processed food product, and is sealed and cut along equally spaced transverse sections to form pillow packs, which are then folded mechanically to form the finished, e.g. substantially parallelepiped-shaped, packages.
  • the packaging material may be cut into blanks, which are folded on forming spindles into packages, which are then filled with the food product and sealed.
  • the so-called "gable-top” package known by the trade name Tetra Rex (registered trademark).
  • packages of the above type may undergo further operations, such as application of a closable opening device.
  • opening devices comprise a frame defining an opening and fitted about a pierceable or removable portion on the top wall of the package; and a cap hinged or screwed to the frame, and which is removable to open the package.
  • a cap hinged or screwed to the frame and which is removable to open the package.
  • other, e.g. slidable, opening devices are also known to be used.
  • the pierceable portion of the package may be defined, for example, by a so-called “prelaminated” hole, i.e. a hole formed in the fibrous layer of the packaging material before it is covered with the barrier layer, which thus remains whole and closes the hole to ensure airtight, aseptic sealing, while at the same time being pierced easily.
  • prelaminated hole i.e. a hole formed in the fibrous layer of the packaging material before it is covered with the barrier layer, which thus remains whole and closes the hole to ensure airtight, aseptic sealing, while at the same time being pierced easily.
  • the opening devices described are normally heat sealed or glued directly to the packages by applicator units, which also perform a number of preliminary steps, such as localized heating or application of adhesive.
  • EP-A-1 228 967 describes an applicator unit substantially comprising a continuously-rotating carousel conveyor for conveying the packages from a loading station to an unloading station via a number of work stations and paths comprising, in particular, a feed station for feeding the opening the opening devices onto the carousel conveyor, and where the opening devices are picked up by respective grippers fitted to the carousel conveyor itself; a number of processing stations for heating the opening devices; and an application station for applying the opening devices to respective packages.
  • an opening device may fail to be supplied to the feed station or to be picked up by the relative gripper. So, to prevent overheating of the empty gripper exposed directly to the heaters in the absence of the opening device, known units are provided with a sensor for detecting the presence of the opening devices; and deflecting devices for intercepting the heat produced by the heaters in response to a sensor-generated signal indicating a missing opening device.
  • a major drawback resulting from failure to apply the opening device to a package lies in the package, filled with the product and of considerable value by being at the end of the production cycle, having to be rejected.
  • an applicator unit as claimed in Claim 1.
  • Number 1 in Figure 1 indicates as a whole a unit for applying opening devices 2 to packages 3 of pourable food products.
  • Packages 3 are produced on a packaging unit (not shown) from a web of sheet packaging material comprising a layer of paper material covered on both sides with layers of heat-seal plastic material, e.g. polyethylene; and a layer of barrier material, such as aluminium, located inwards with respect to the layer of paper material, and in turn covered internally by another layer of plastic material.
  • a web of sheet packaging material comprising a layer of paper material covered on both sides with layers of heat-seal plastic material, e.g. polyethylene; and a layer of barrier material, such as aluminium, located inwards with respect to the layer of paper material, and in turn covered internally by another layer of plastic material.
  • Each package 3 which is parallelepiped-shaped in the example shown, has, on a top wall 4, a pierceable portion 5 conveniently defined by a so-called “prelaminated” hole, i.e. a hole formed in the fibrous layer of the packaging material before the fibrous layer is covered with the barrier layer, which closes the hole to ensure airtight, aseptic sealing, while at the same time being easily pierceable.
  • prelaminated hole i.e. a hole formed in the fibrous layer of the packaging material before the fibrous layer is covered with the barrier layer, which closes the hole to ensure airtight, aseptic sealing, while at the same time being easily pierceable.
  • Opening devices 2 are made of thermoplastic material, and each comprise in known manner a frame 6, which is heat sealed about pierceable portion 5 on wall 4 of a respective package 3, and defines a pour opening (not shown); and a cap 7 or cover screwed or hinged to the frame to close said opening. Opening devices 2 conveniently comprise known means, not shown, for piercing or removing pierceable portion 5 of package 3 to unseal the package.
  • Unit 1 comprises a first conveying device defined by a linear step conveyor 8 for feeding a succession of packages 3 along a preferably straight path P1; a second linear step conveyor 9 for feeding a succession of opening devices 2 along a straight path Pr parallel to and in the opposite direction to path P1 in the example shown; and a step-operated carousel conveyor 10, which rotates about a vertical axis A, has a number of grippers 11 for gripping opening devices 2, and feeds opening devices 2 from a pickup station 12 coincident with one of the stop stations of second conveyor 9, to an application station 13 for applying opening devices 2 to respective packages 3, and which is coincident with one of the stop stations of first conveyor 8.
