Definitions

  • the present invention relates to a packaging assembly, particularly indicated for packaging food products such as chocolates of various shapes, chocolate eggs and the like.
  • the packaging of chocolates and, in particular, the packaging of chocolate eggs (of any size) is generally carried out using sheets of aluminum (or multilayer sheets that comprise a layer of aluminum).
  • a single sheet of aluminum is normally folded around the external surface, in order to cover it in a substantially continuous manner.
  • This type of packaging does not enable the sheet to be closed in a completely stable manner, and it does not ensure the perfect isolation of the product with respect to the outside environment.
  • the aim of the present invention is to solve the above mentioned drawbacks, by providing a packaging assembly that ensures a high stability of the packaging sheet applied on the product.
  • an object of the invention is to provide a packaging assembly that makes it possible to optimally package the product, thus protecting it from the outside environment.
  • Another object of the invention is to provide a packaging assembly that makes it possible to provide a packaging that is better and more efficient, with respect to conventional types of packaging, for chocolate eggs and the like.
  • Another object of the present invention is to provide a packaging assembly that is of low cost, easily and practically implemented, and safe in use.
  • a packaging assembly of the type comprising a carousel provided with a plurality of processing stations arranged in succession, including a gripping station in which respective gripping elements receive at least one single product with the interposition of a covering sheet arranged in a U-shaped configuration in partial juxtaposition with the product with two protruding free flaps, at least one covering and folding station, and a delivery station for delivering said product to an outflow line, characterized in that said gripping station comprises:
  • the reference numeral 1 generally designates a packaging assembly according to the invention.
  • the packaging assembly 1 comprises a carousel 2 which is provided with a plurality of processing stations arranged in succession.
  • the assembly 1 comprises a first gripping station 3 in which respective gripping elements 4 receive at least one single product (P) with the interposition of a covering sheet A arranged in a U-shaped configuration in partial juxtaposition with the product P with two protruding free flaps B.
  • the arrangement of the sheet A on the product is obtained by virtue of the presence of a hopper through which the product P passes (conveyed by a respective elevator).
  • the sheet A is arranged immediately downstream of the hopper, so that the product P, passing through it, also entrains the sheet A, in so doing juxtaposing it partially against the surface of the product P with which the sheet A comes into contact, according to a technique that is known in the sector.
  • the sheet A is kept in contact with a part of the surface of the product P by a "bracing elevator" which, in fact, blocks the sheet A by pressing it against the product P (this component, since it is conventional, is not specifically illustrated in the accompanying figures).
  • the carousel 2 further comprises at least one covering and folding station 5 and a delivery station 5a for delivering the product P to an outflow line, not shown in the accompanying figures.
  • the gripping station 3 comprises at least two mutually opposite pushers 6, which are substantially aligned with a surface of the product P.
  • the surface of the product P with which the pushers 6 are substantially aligned is the corresponding lower surface.
  • Such surface i.e., the lower surface in the graphic examples provided merely by way of non-limiting example
  • Such surface is delimited by the two free flaps B of the sheet A, while the product P is held by the gripping elements 4.
  • the pushers 6 are conveniently movable between a first configuration of maximum mutual distance (visible merely by way of non-limiting example in Figure 5 ) and a second configuration of substantial mutual abutment of the respective terminal fronts 7 with the interposition of the mutually juxtaposed flaps B (visible merely by way of non-limiting example in Figure 6 ).
  • the movement of the pushers 6 is preferably synchronous, although different modes of movement are not ruled out.
  • a first pusher 6 moves by performing a translation and therefore always remaining parallel to its axis of extension; a second pusher 6 (the one shown merely by way of non-limiting example on the right in the figures) moves according to a substantially circular trajectory.
  • a first pusher 6 moves by performing a translation and therefore always remaining parallel to its axis of extension;
  • a second pusher 6 moves according to a substantially circular trajectory.
  • Such examples are provided merely for illustrative purposes, in that different laws of motion and trajectories for the pushers 6 can also be envisaged while remaining within the inventive concept identified by the present discussion.
  • the gripping station 3 further comprises at least one folding unit 8 aligned with the lower surface of the terminal front 7 of at least one of the pushers 6, for folding the mutually juxtaposed flaps B onto themselves so as to define a folded seam C (the type of folded seam C that it is intended to provide with the flaps B of the sheet A is shown merely by way of non-limiting example in Figure 9 ).
  • At least one of the pushers 6 can conveniently comprise, on its terminal front 7, an element which is provided with a tab designed to surmount the front 7 of the other pusher 6 (with an arrangement visible merely by way of non-limiting example in Figure 6 ) when the two fronts 7 are in configuration of mutual abutment: such element will therefore define the folding unit 8 and can generate a fold through 90° of the flaps B, with respect to the portion thereof that is clamped between the two terminal fronts 7 (as visible merely by way of non-limiting example in Figure 6 ).
  • the element previously described could conveniently comprise a folding flap 9 which can rotate between a first configuration, in which it is contiguous with and perpendicular to the terminal front 7 of the respective pusher 6 (the configuration shown merely by way of non-limiting example in the accompanying Figures 5 , 6 , 8 and 9 ), and a second configuration, in which the flap 9 is rotated through substantially 90° with respect to the first configuration, being arranged so that it faces and is proximate to the terminal front 7 of the respective pusher 6 (the configuration shown merely by way of non-limiting example in the accompanying Figure 7 ).
  • the element previously described could advantageously comprise a substantially cylindrical seat 10 which is integral with the terminal front 7 of the respective pusher 7.
  • a semicylindrical insert 11 can then be rotatable about its own axis within such seat 10 and be coaxial with such seat 10.
  • the folding flap 9 will therefore be coinciding with a portion of the flat face of the insert 11.
  • a contoured guide 12 is arranged between the gripping station 3 and the subsequent folding station 6 and is provided with a band 13 for folding the folded seam C.
  • the folding band 13 substantially coincides with the trajectory of the external surface, with respect to a radial direction referred to the carousel 2, of the product P partially covered by the sheet A, for the juxtaposition of the folded seam C on the external surface of the sheet A when having a substantially tubular shape (by way of non-limiting example the product P is shown partially covered by the sheet A in a configuration of proximity to the band 13 in the accompanying Figure 9 , using a dotted line).
  • the assembly 1 further comprises, at the gripping station 3, at least one shape retention element 14 for the sheet A.
  • the shape retention element 14 performs its function at the time of the operations to fold the sheet A, up to when the sheet A is partially wrapped on the product P and assumes a substantially tubular shape (the shape retention element 14 is no longer needed after the folded seam C has been fully completed).
  • the shape retention element 14 will advantageously comprise at least one substantially prismatic body 15 which has a cross-section that is complementary to the cross-section of the sheet A, when wrapped to form a tube, for its insertion into the wrapped sheet A during the operations to juxtapose the flaps B and form the corresponding folded seam.
  • substantially prismatic body 15 can be cylindrical, conical, frustum-shaped, pyramidal, truncated-pyramidal, polyhedral and a combination thereof.
  • the assembly 1, according to a particularly advantageous embodiment, can positively comprise a support shelf 16 for supporting the substantially prismatic body 15 of the at least one shape retention element 14.
  • the shelf 16 will be arranged parallel to the axis of the sheet A when wrapped to form substantially a tube.
  • the shelf 16 will comprise at least one slider 17 which can translate longitudinally, to which an upright 18 will be coupled which is designed to support the substantially prismatic body 15.
  • At least one covering and folding station 6 (arranged downstream of the gripping station 3) will comprise movable apparatuses (which may be of a substantially conventional type) for arranging the free end portions of the sheet A, which was previously folded in a tubular shape, against corresponding surfaces of the product P.
  • the sheet A will be juxtaposed against the surface of the product P, in so doing passing from the substantially tubular shape to having a shape and dimensions that match those of the product P (of which it will constitute a surface covering).
  • the present invention solves the above mentioned problems, by providing a packaging assembly 1 that ensures a high stability of the packaging sheet A applied on the product P, by virtue of the possibility of providing a folded seam C between the flaps of the sheet A that is wrapped around the product P.
  • the assembly 1 according to the invention makes it possible to optimally package the product, in so doing protecting it from the outside environment: the presence of the folded seam C, in fact, ensures that the two flaps B do not come away from each other.
  • the packaging assembly 1 makes it possible to provide a package that is better and more efficient, with respect to conventional types of packaging, for chocolate eggs and the like, although having the same appearance and being provided with the same materials (generally sheets A of aluminum).
  • the present invention makes it possible to provide a packaging assembly that is easily and practically implemented and which is of low cost: such characteristics make the assembly 1 according to the invention an innovation that is certain to be safe in use.
  • the materials employed, as well as the dimensions, may be any according to requirements and to the state of the art.
