Definitions

  • the present invention relates to a wrapping unit designed for the packaging mainly of chocolates, candy, small pastries and the like, hereinafter generically termed products.
  • Packaging devices are known which provide for covering each individual product with a sheet made of a material preferably chosen among polymeric, metallic, paper and combinations thereof.
  • the flaps of this covering sheet can be mutually sealed (cold or with heat) for better isolation of the contained product and a consequent protection thereof against atmospheric and environmental agents.
  • devices of the known type provide for the shaping of a tubular covering for the product (obtained by wrapping the sheet around the product itself) in which a notch is preferably provided which ensures the possibility to open the package easily on the part of the user.
  • the further closure stations of the known type are not versatile and are therefore suitable to perform a single type of packaging.
  • wrapping machines of the known type are also particularly specific: each of them is normally designed to provide a single type of wrapping; the poor versatility of machines of the known type makes them less appealing for potential clients.
  • WO 2014/097235 discloses a method for packaging articles to form a tubular wrapping of thermosealable sheet material inside which the articles to be packaged are prearranged, regularly distanced, and to feed the tubular wrapping to a cut station at which grip means, suitable to grasp in succession the articles, operate.
  • the transverse cut of the tubular wrapping is performed in suitable step relationship in the section upstream the article grasped by the grip means and the prepackaged article is transferred to a closure rotatable head for closing the package, rotatable at a plurality of operative stations.
  • a first operative station the bellows folding of the open ends of the portion of tubular wrapping containing the article is performed.
  • the sealing of the bellows folded ends of the wrapping is performed to obtain the airtight closure of the package.
  • the aim of the present invention is to solve the problems described above, providing a wrapping unit that is versatile and therefore suitable to generate wrappings with different characteristics on the processed products.
  • an object of the invention is to propose a wrapping unit in which format changing operations are particularly easy.
  • Another object of the invention is to propose a wrapping machine that is versatile.
  • a further object of the present invention is to provide a wrapping assembly and a wrapping machine that have modest costs, are relatively simple to provide in practice and safe in application.
  • a wrapping unit is generally designated by the reference numeral 1.
  • the wrapping unit 1 comprises at least one gripper 2 which is provided with mutually opposite jaws 3 for clamping at least one end of a tubular blank A that contains a product B to be packaged.
  • At least one of the jaws 3 comprises at least one air extraction unit 4 to extract air from the inside of the tubular blank A simultaneously with its clamping.
  • a unit 1 provided with a single gripper 2 allows to provide so called “singletwist” wrappings (generally termed “twist on top” wrappings), in which the product B is in contact with a closed base of the wrapping sheet (the blank A is therefore closed at one end and is not a tubular element provided with a through opening) and its open tubular portion is clamped by the gripper 2 and subsequently (in a subsequent station) subjected to twisting (rolling up onto itself with respect to its own axis).
  • so called “singletwist” wrappings generally termed “twist on top” wrappings
  • the product B is in contact with a closed base of the wrapping sheet (the blank A is therefore closed at one end and is not a tubular element provided with a through opening) and its open tubular portion is clamped by the gripper 2 and subsequently (in a subsequent station) subjected to twisting (rolling up onto itself with respect to its own axis).
  • the grippers 2 can validly be at least two, which face each other.
  • the grippers 2 are mutually arranged at a distance that is substantially similar to the length of the tubular blank A, so that when the blank A is arranged between them its portions that protrude externally with respect to the product B are aligned with the jaws 3 (which close, clamping them).
  • a first gripper 2 is preset to clamp a portion of the tubular element A that is arranged upstream of the product B contained therein, while a second gripper 2 is preset to clamp a portion of the tubular element A arranged downstream of the product B contained therein.
  • the tubular blank A comprises, along its internal surface, areas that can be sealed.
  • the sealable areas that are internal to said portion make mutual contact and mate.
  • sealable areas are adopted which are constituted by layers of adhesive (which can be active at room temperature or can be activated after heating or following clamping) which ensure perfect cohesion of the affected surfaces, with consequent isolation and segregation of the product B within the tubular blank A after the clamping performed with the grippers 2.
  • At least one jaw 3 of each gripper 2 can comprise effectively an air extraction unit 4 for extracting air from the inside of the tubular blank A simultaneously with its clamping.
  • the at least one jaw 3, more precisely the air extraction unit 4 thereof, comprises an oscillating terminal clamp 5, intended to abut against the tubular blank A.
  • the air extraction unit 4 is in fact operational by virtue of the sliding of the clamps 5 on the surface of the tubular blank A (as close as possible to the product B): progressively, the clamps 5 move into mutual contact, compressing the tubular blank A and therefore in practice eliminating the air.
  • the clamp 5 is pivoted to the respective jaw 3 with respect to a pivot 6: the clamp 5 can oscillate freely or can be controlled by a respective actuator.
  • elastic means are arranged which are designed to keep the clamp 5 in a rotated configuration of maximum distance from the respective jaw 3: upon the clamping of the gripper 2, the terminal end of each clamp 5 is the first part of the jaw 3 that makes contact with the tubular blank A, facilitating the stretching of the sheet (which constitutes the blank A) along the product B and the exit of the air that is present between them; therefore it ensures the provision of a covering that perfectly replicates the shapes of the product B.
  • the at least one jaw 2 comprises a heater 7 for increasing the temperature of a surface thereof that abuts against the tubular blank A.
  • the clamping of a portion of the blank A on the part of the gripper 2 provided with at least one jaw 3 that has a heated portion causes the heat-sealing of the portions (of the flaps) of the tubular blank A that are mutually pressed against each other.
  • the present invention is also suitable to form an entire wrapping machine which comprises a packaging carousel provided with a plurality of consecutive stations.
  • the carousel comprises a first forming station.
  • the forming station is provided with grip means for receiving the product B from a supply unit and with mutual coupling elements for the flaps of a covering sheet.
  • the packaging sheet is conveniently arranged between the grip means and the supply unit.
  • the grip means therefore clamp the product B with the interposition of the packaging sheet, forming a partial wrapping of the product on the part of said sheet.
  • the coupling elements mutually join the protruding flaps of the sheet that is partially wrapped around the product B until they constitute a tubular blank A that contains the product.
  • the carousel further comprises, downstream of the forming station, a wrapping unit 1, which comprises at least one gripper 2 that is provided with mutually opposite jaws 3 for the clamping of at least one end of the tubular blank A that contains a product B to be packaged (blank A provided by the forming station in a preceding step).
  • a wrapping unit 1 which comprises at least one gripper 2 that is provided with mutually opposite jaws 3 for the clamping of at least one end of the tubular blank A that contains a product B to be packaged (blank A provided by the forming station in a preceding step).
  • At least one of the jaws 3 comprises, in this case, at least one air extraction unit 4 for extracting the air from the inside of the tubular blank A simultaneously with its clamping.
  • the carousel further comprises a twisting station, arranged downstream of the wrapping unit 1, which comprises at least one rotatable pair of pincers which is preset to clamp at least one of the ends of the tubular blank A that contains the product B and is closed at at least one end.
  • a twisting station arranged downstream of the wrapping unit 1, which comprises at least one rotatable pair of pincers which is preset to clamp at least one of the ends of the tubular blank A that contains the product B and is closed at at least one end.
  • the twisting station performs the function of rolling onto itself the at least one end of the tubular blank A that is arranged upstream and/or downstream of the product B contained therein.
  • the carousel comprises, finally, an expulsion station that is designed to deliver the product A wrapped within the closed and partially rolled up sheet to a predefined exit area.
  • the coupling elements that are present in the forming station and at least one of the mutually opposite jaws 3 of the forming unit 1 can validly comprise respective heaters 7 for the heat-sealing of the flaps of sheet that are clamped and juxtaposed by them.
  • the coupling elements of the forming station can comprise effectively a blade for cutting the flaps of the sheet that are clamped by them.
  • Such blade is movable between a retracted configuration, at an arrangement of mutual separation of the coupling elements, and a protruding configuration, at an arrangement of mutual abutment of the coupling elements.
  • the wrapping unit 1 can validly comprise at least two grippers (ensuring the possibility to provide wrappings of the so-called "double-twist” type), which face each other and are arranged at a mutual distance that is substantially similar to the length of the tubular blank A.
  • a first gripper 2 is preset to clamp a portion of the tubular element A arranged upstream of the product B contained therein
  • a second gripper 2 is preset to clamp a portion of the tubular element A arranged downstream of the product B contained therein.
  • At least one jaw 3 of each gripper 2 comprises at least one air extraction unit 4 for extracting the air from inside the tubular blank A simultaneously with its clamping.
  • the present invention solves the previously described problems, proposing a wrapping unit 1 that is versatile and therefore suitable to generate wrappings with different characteristics on the processed products.
  • the unit 1 in fact allows to provide wrappings of the type known as "double twist", and in general sealed wrappings.
  • the wrapping unit 1 ensures that the format changing operations are particularly easy: the unit in fact has a structure that is simple and can be disassembled easily by any specialized operator.
  • the wrapping machine according to the invention also is versatile, allowing the provision of wrappings of various shapes and of the sealed type.
  • the present invention defines a wrapping unit 1 and a wrapping machine that are relatively simple to provide in practice and have modest costs, such as to render them technical solutions of assured application.
  • the materials used, as well as the dimensions, may be any according to the requirements and the state of the art.
