Definitions

  • the present invention refers to the packaging and it relates to a device for packaging in a modified atmosphere particularly fit to the preparation of the foods selling.
  • Said known devices known as compensated vacuum type devices, need to create the vacuum in a vacuum chamber with a valves system and a valves pump and, consequently, has the disadvantage to require long packaging periods of time.
  • gas flushing devices which forms a tube or a bag, open in a side into which the product is inserted. Said bag or tube having one open side and containing the product, is subjected internally to a continuous gas flush which discharges the air and substitute it.
  • Said known gas flushing devices have a great productivity and work in an only cycle but have the disadvantage of consuming a lot of gas and do not substitute completely the air in the package.
  • An object of the present invention is to propose a fast and low gas consuming device for the packaging in a modified atmosphere.
  • Another object is to propose a device to obtain packages with the desired level of air substitution with a gas.
  • Another object is to propose a device almost without wastes of packaging material and of gas at the start up.
  • a further object is to propose a compact, reliable and cheap device.
  • the device is supplied by suitable, known and not shown apparatuses with a film, known as "mono-folded" film, made of a thermoweldable material M in ribbon or membrane, for instance wrapped as a spool.
  • a film known as "mono-folded" film, made of a thermoweldable material M in ribbon or membrane, for instance wrapped as a spool.
  • Said ribbon is folded longitudinally in half, and thus it has two longitudinal edge s having almost the same length and separated by said longitudinal folding.
  • the device comprises first conveyor means 3, for instance of tape, belt or similar type, fit to convey the product P over an almost horizontal plane and towards an advancing direction A up to an operating support of the device 1, said product consisting, as an example, in a food contained in a basin or in other similar objects.
  • the supplying apparatuses of the film made of material M provide and place one of the edges of said material below the lower side of the first conveyor means 3 and place the edge superiorly to the product P and to said first conveyor means 3.
  • the device comprises second conveyor means 19, parallel to the supplying direction A and slightly staggered in respect to the first conveyor means 3 from which they are separated by means of a slot 20 for the passing of the of the lower edge, that was below the first conveyor means 3, over said second conveyor means 19 which thus support, from the lower part, the edge which has passed the slot 20, the product P and the upper edge.
  • the device 1 has transversal clamping means 7 comprising two transversal rolls 11, 12 respectively lower and upper to the two edges of the material and mutually mobile between a spaced condition, for the passage of the product interposed between the edges, and a mutual match condition for the clamping of a transversal edge portion.
  • the device 1 comprises longitudinal clamping means 8 and longitudinal pulling means 13 lateral to the second conveyor means 19 and placed in sequence downstream of the transversal clamping means 7. Said longitudinal clamping means 8 and longitudinal pulling means 13 cause the mutually matching and the pulling in the advancing direction A of the longitudinal portions of the free borders of the edges of the material M.
  • the longitudinal clamping means are constituted by only one element provided with a first pair of rolls 14, 15 placed at the upper lateral side of the free borders of the edges of the material M and of a second pair of rolls 16, 17 placed at the lower side of the free borders of the edges of the material M.
  • the rolls of the second pair 16, 17 are faced to the rolls of the first pair 14, 15 and almost match with said first pair 14, 15 in order to clamp said borders.
  • At least one of said rolls 14, 15, 16, 17 is motorized in order to pull the borders; preferably they are activated by a roll lower motor 16 and an upper roll 14 placed downstream of the others.
  • two ring-like flexible means engaged respectively to the first pair of rolls 14, 15 and to the second pair of rolls 16, 17 realizing a kind of opposed tracks.
  • the device is provided with insufflating means 5 comprising at least a nozzle 18 interposed between the borders portions of the edges of the material M comprised between the rolls 14, 15, 16, 17 and fit to deliver a gas between said two edge portions.
  • the device comprises also welding means 6 fit to weld and to seal a longitudinal border and a transversal portion of the edge made of the thermoweldable material M adjacent to the longitudinal 8 and transversal 7 clamping means, obtaining a package realized with said material M and containing the product P in a modified atmosphere, comprising the insufflated gas by means of the nozzle 18.
  • the welding means 6 have a two, upper and lower, "L" shaped members, placed in the opposite, upper and lower, sides of the edges made of the material M.
  • Said upper and lower "L" members of the welding means 6 are mutually moved by known but not shown activating means between a resting spaced apart condition, for the product passage, and a welding condition in which they almost mutually match each other and they match with the material in order to weld the edges thereof.
  • Each "L” member, lower and upper has a correspondent longitudinal element 9 placed almost corresponding to the free borders of said edges, and inside the longitudinal clamping means 8 and has a respective transversal element 10 orthogonal to the longitudinal one 9 and placed downstream of the transversal clamping means 7.
  • the nozzle 18 has a planar and profiled shape for the free sliding, along its opposite sides, of the edges borders of the material M with the minimum possible separation between them
  • the device 1 may also comprise pressing means 21 associated to the welding means 6 and fit to elastically press an edge of the material M towards the product
  • the pressing means 21 plan view is about quadrangular shaped, with two side fixed to and corresponding to the longitudinal 9 and transversal 10 elements, placed at the upper side of the edges of the material M, of the welding means.
  • the pressing means 21 comprises a cushion made of soft and elastic material, as an example foam rubber, or of a pneumatic type.
  • the second conveyor means 19 extends from the welding means 6, supporting the product P and the material M in correspondence to said welding means and conveying the outgoing packaged product P, or towards others apparatuses or through, known and not shown, heating means, associated thereto and placed downstream of the welding means 6, fit to the retraction of the thermo-retractable material M.
  • the device 1 comprises control means of the motors, activating and insufflating means 5.
  • Said control means may be programmable and may adjust the flow and/or the quantity of the insuflfated gas between edges of the material by the insufflating means 5 comprising adjusting and closing electric valves.
  • the device 1 may be provided with known and not shown sensing means placed between the edges and connected to the control means in order to supply thereto data about the modified atmosphere.
  • control means may feedback control the insufflating means 5 in order to obtain a predetermined modified atmosphere for the packaging.
  • the operating of the device starting from an initial condition in which the product is over the first conveying means 3 near to the slot 20, the material has a transversal welding made during a previous cycle and the transversal clamping means 7 and the two "L" members, upper and lower, of the welding means 6 are in the mutually spaced apart conditions, it provides that the coordinated activation of the first 3 and second 19 conveyor means and of the longitudinal pulling means 13 carries the product, contained between the two prior welded edges of the material in the portion of the second conveyor means corresponding to the operating zone of the welding means 6 and of the transversal 7 and longitudinal 8 clamping means.
  • the approaching of the two upper and lower “L" members of the welding means 6 realizes first of all the ejection of the exceeding atmosphere thanks to the pressing means 21 and then the mutual welding of the edges, thus obtaining the packaging in a modified atmosphere of said product.
  • An advantage of the present invention is to provide a fast and low gas consuming device for the packaging in a modified atmosphere.
  • Another advantage is to provide a device to obtain packages with the desired level of air substitution with a gas.
  • Another advantage is to provide a device almost without wastes of packaging material and of gas at the start up.
  • a further advantage is to provide a compact, reliable and cheap device.
