Definitions

  • the present invention relates to a packaging machine, in particular of the type suitable for wrapping and sealing a product inside a package produced with a sheet that is folded and, optionally, heat-sealed.
  • first wrapping produced with a sheet of minor thickness (generally made of aluminum or paper or polymeric material or combinations thereof), which constitutes what is termed primary packaging
  • second wrapping produced with a carton or a sachet or a box-like element, which constitutes what is termed secondary packaging.
  • the product is subjected to wrapping (enveloping or boxing or placing in a sachet), while a respective fixed line is maintained for the machine.
  • fixed line means a line (or a plane) that corresponds to a part of the product to be packaged (or to a portion of the carton into which a product is to be inserted) with respect to which the movement and packaging operations will refer.
  • the aim of the present invention is to solve the above-mentioned drawbacks, by providing a packaging machine that guards against any damage to the top face of the product to be packaged, by preventing abrasions thereof along the conveyance line.
  • an object of the invention is to provide a packaging machine that makes it possible to facilitate and speed up the secondary packaging operations, in particular the operations of cartoning and/or boxing.
  • Another object of the invention is to provide a packaging machine that makes it possible to carry out the primary packaging (wrapping) of products, while maintaining a predefined alignment thereof in various areas of the machine.
  • Another object of the invention is to provide a packaging machine that allows high operating speeds without this resulting in damage to the product.
  • Another object of the present invention is to provide a packaging machine that is of low cost, easily and practically implemented, and safe in use.
  • a packaging machine which is characterized in that it comprises:
  • the reference numeral 1 generally designates a packaging machine according to the invention.
  • the machine 1 comprises a first conveyor 2, along which each product P to be packaged advances while keeping its top face, which is opposite to the bottom face that rests on the surface 3 of the first conveyor 2, coplanar with respect to the top face of other products P that are present on the surface 3 of the first conveyor 2, thus defining an upper fixed line along the plane that comprises the top faces of the products P.
  • the machine 1 further comprises a second conveyor 4, along which each wrapped product W advances while keeping its bottom face, which is opposite to the top face that rests on the surface 5 of said second conveyor 4, coplanar with respect to the bottom face of other wrapped products W that are present on the surface of the second conveyor, thus defining a lower fixed line along the plane that contains the surface 5.
  • the machine 1 comprises a primary wrapping wheel 6, which is interposed between the first conveyor 2 and the second conveyor 4 and is configured to receive at least one product P from the first conveyor 2 and at least one wrapping sheet A, in order to wrap the at least one product P in such at least one wrapping sheet A and deliver the wrapped product W upside down to the second conveyor 4.
  • the top face of each product arranged on the first conveyor 2, the bottom face of each wrapped product W arranged on the second conveyor 4, and the rotation axis X of the wrapping wheel 6 advantageously lie on a same reference plane Y.
  • the machine 1 can conveniently comprise, downstream of the second conveyor 4, a cartoning assembly 7 provided with a receiving station 8 for receiving at least one wrapped product W with the bottom face lying on the reference plane Y, and a stage for supplying a contoured laminar element (such as a die-cut sheet of cardboard), not shown in the accompanying figures.
  • a contoured laminar element such as a die-cut sheet of cardboard
  • Such stage will profitably be configured to arrange the laminar element below the wrapped product W which is present in the receiving station 8.
  • the machine 1 according to the invention can further comprise a folding hopper 9 for the laminar element, which is arranged below the laminar element and the wrapped product W when it is accommodated in the station 8, and an actuator (not visible in the accompanying figures) configured to make the wrapped product W pass through the hopper 9, with consequent entrainment and juxtaposition of the contoured laminar element onto surfaces of the wrapped product W.
  • a folding hopper 9 for the laminar element which is arranged below the laminar element and the wrapped product W when it is accommodated in the station 8, and an actuator (not visible in the accompanying figures) configured to make the wrapped product W pass through the hopper 9, with consequent entrainment and juxtaposition of the contoured laminar element onto surfaces of the wrapped product W.
  • the machine 1 can usefully also comprise a third conveyor 10, arranged below the hopper 9, for receiving the wrapped product W partially covered by the contoured laminar element (i.e. by the secondary wrapping).
  • a third conveyor 10 arranged below the hopper 9, for receiving the wrapped product W partially covered by the contoured laminar element (i.e. by the secondary wrapping).
  • the primary wrapping sheet A will generally be constituted by a sheet of aluminum or of paper or of polymeric material (or a combination thereof), while the contoured laminar element will generally be constituted by a sheet of cardboard or polymeric material (or a combination thereof).
  • the first conveyor 2 can profitably comprise adjustment means for changing the format of the product P to be translated, which are configured at least to change the elevation of the surface 3 of the first conveyor 2 on which the bottom face of the product P rests.
  • This ability to change the elevation of the surface 3 will determine the consequent adjustment of its distance from the reference plane Y (which constitutes the upper fixed line of the first conveyor 2) as a function of the thickness of the product P.
  • specific elements can profitably be arranged along the second conveyor 4 and are configured for at least one action chosen among folding, adhesive bonding and heat-sealing of the protruding lateral flaps of the wrapping sheet A which is partially wrapped around the product P. That is to say, in practice, during the first steps of translation of each product P, the wrapping sheet A will be closed around it until the complete achievement of the wrapped product W, which corresponds to the completion of the primary wrapping.
  • these specific elements comprise at least one adjustment device, for changing the format of the product P to be translated, which is configured at least to change the elevation of these elements with respect to the surface 5 of the second conveyor 4 which is aligned with the reference plane Y and which constitutes the upper fixed line.
  • This adjustment device will make it possible to modify the elevation, described above, as a function of the thickness of the wrapped product W.
  • the machine 1 according to the invention can furthermore advantageously comprise adjustment elements for changing the format of the product P to be translated, which are configured at least to change the elevation of at least one component chosen among the stage for supplying a contoured laminar element and the actuator.
  • the finished products K i.e. which comprise the primary wrapping and the secondary wrapping
  • the primary wrapping wheel 6 comprises grip means for at least one product P which is at least partially wrapped in the wrapping sheet A and at least one operating module 11, 12 which is arranged along the trajectory 13 defined by the grip means.
  • the at least one operating module 11, 12 is adapted for performing at least one activity chosen among folding, adhesive bonding, heat-sealing, cooling, and cutting/scoring of flaps of the wrapping sheet A.
  • At least one component chosen among the first conveyor 2, the second conveyor 4 and the third conveyor 10 can positively comprise protrusions distributed on its surface that is designed for the resting and conveyance of the bottom face of the products P.
  • protrusions will be adapted to abut against an edge of a respective product P (or wrapped product W, or final product K) for a predefined linear spacing of the respective products P (or W or K) that are present on the respective surface.
  • the fixed line engineered in the front plane is also overturned as it moves from upstream to downstream of the wheel 6.
  • the machine 1 takes the plane containing the top faces of the product P as the fixed line of its first part (corresponding to the first conveyor 2). The adjustments to change format in this part of the machine 1 will therefore be performed by moving the conveyor 2 so that the products P conveyed always keep their top face lying on this plane.
  • the rotation imposed by the wrapping wheel 6 will ensure that the upper part (the part for which maintenance of the aesthetic characteristics must be ensured) is no longer affected by any adjustments to components dependent on change of format, which will always operate on the bottom face of the product and on its sides.
  • the machine 1 can ensure that the fixed line of the initial part (corresponding to the first conveyor and to the area for receiving the product P and the sheet A in the wrapping wheel 6), which will be an upper fixed line, is aligned with the lower fixed line exiting the wheel 6, since both lie on the reference plane Y.
  • rotation axis X of the wheel 6 will also lie on the plane Y.
  • the overturned product W proceeds, with the face the aesthetic qualities of which are to be preserved directed downward, up until the subsequent cartoning assembly 7 which is designed to perform the secondary wrapping (or outer wrapping).
  • the drawing-through will necessarily be performed downward, with the advantage that the component that is designed to support the wrapped product W and the laminar element (a lowering device which faces the face bearing the aesthetic qualities of the product P which are to be preserved) no longer has to abandon it in order to make space for other components intended for specific movements (something that does not occur in the known art, in which a classic architecture is adopted in which such drawing-through is performed upward).
  • the element that supports the product W and the laminar element after they have passed through the hopper 7 must be moved away from the hopper 7 and the product K (understood as the set of the product W and of the laminar element) would have to be supported by other components which have the twofold purpose of folding the flaps and, indeed, supporting it.
  • the present invention solves the above-mentioned problems, by providing a packaging machine 1 that avoids any damage to the top face of the product P to be packaged, by preventing abrasions thereof along the conveyors 2, 4 and 10.
  • the machine 1 according to the invention makes it possible to facilitate and speed up the secondary packaging operations, in particular of cartoning and/or boxing.
  • the machine 1 makes it possible to carry out the primary packaging (wrapping) of products P, while maintaining a predefined alignment thereof in various areas of the machine 1.
  • the machine 1 according to the invention allows high operating speeds without this resulting in damage to the product P.
  • the machine 1 according to the invention is easily and practically implemented and is of low cost: such characteristics make the machine 1 according to the invention an innovation that is safe in use.
  • the materials employed, as well as the dimensions, may be any according to requirements and to the state of the art.
