Definitions

  • the present invention relates to a vacuum packaging machine.
  • Vacuum packaging machines which allow to package food products in sealable vacuum bags and which generally have a base, which defines a vacuum chamber, that can be connected to a vacuum pump and is provided with an access opening, which can be closed hermetically by means of an openable lid, for inserting and extracting the food product packed in the vacuum bag from the vacuum chamber.
  • Vacuum packaging machines in particular are known which are configured like a drawer, so as to be used in kitchen furniture, and worktop models and wheeled models, both for household and professional use, are also known.
  • Machines of this type usually have the lid articulated to the base by means of self-balancing rotatable hinges or more complex mechanical elements provided with gas cylinder actuators, so that the opening and closing of the lid is conditioned by the stiffness of the gas cylinder actuators or of the self-balancing rotatable hinges.
  • the solutions used so far for the articulation of the lid to the base provide a hinging axis of the fixed lid, whereby when the lid is closed onto the base the gasket that seals the lid and the vacuum chamber first makes contact with the rear side of the base, i.e., the side that is parallel and proximate to the hinging axis of the lid, and also with the opposite side only after complete closure.
  • this raised arrangement of the lid in the inactive position entails a risk of interference of the lid with the flush-mounting container in which the machine is inserted, to the point of being able to prevent the exit of the drawer from the container.
  • the aim of the present invention is to provide a vacuum packaging machine that is capable of improving the background art in one or more of the above mentioned aspects.
  • an object of the invention is to provide a vacuum packaging machine that allows perfect closure of the lid.
  • Another object of the present invention is to provide a vacuum packaging machine that is extremely reliable and safe during use.
  • an object of the present invention is to overcome the drawbacks of the background art in a manner that is alternative to any existing solutions.
  • Another object of the invention is to provide a vacuum packaging machine that can be manufactured with relatively modest costs and is appreciable also from an aesthetic point of view.
  • the vacuum packaging machine generally designated by the reference numeral 1, comprises a base 2 which forms a vacuum chamber 3 provided, preferably at a substantially horizontal flat surface arranged on the upper side of the base 2, with an access opening 4, that can be closed by a lid 5, which is, in turn, articulated to the base 2 by means of at least one hinge device 6.
  • the machine is, for example, structured to be used in a drawer, but can be optionally configured also as a worktop machine or wheeled machine.
  • the vacuum chamber 3 a food product packaging bag and the vacuum chamber 3 can be connected to a vacuum pump, accommodated in the base 2, so that following the actuation of the vacuum pump, after closing the access opening 4 of the vacuum chamber, by means of the lid 5, it is possible to create vacuum in the bag, which is subsequently sealed by means of a heat-sealing bar accommodated in the vacuum chamber itself.
  • the particularity of the invention resides in that it comprises means for moving the lid 5, with respect to the base 2, along a movement direction 7 that is substantially perpendicular to the plane of arrangement of the access opening 4 of the vacuum chamber 3.
  • these movement means are provided by making the hinge device 6 movable, with respect to the base 2, along the above mentioned movement direction 7.
  • the hinge device 6 allows the vertical lowering of the lid 5, i.e., its movement toward the access opening 4, during vacuum generation, and also allows the lid 5 to assume, with the machine inactive, a practically horizontal position, i.e., a position that is substantially parallel to the plane of arrangement of the access opening 4, thus ensuring an optimum contact, along all the extension, of the gasket of the lid 5 with the corresponding abutment region defined on the base 2 around the access opening 4.
  • the movement of the hinge device 6, with respect to the base 2, along the movement direction 7, occurs in contrast with or by virtue of the action of elastic means 8.
  • the hinge device 6 allows to compensate for the vertical movement, i.e., at right angles to the access opening 4, to which the lid 5 is subjected when vacuum is generated in the vacuum chamber 3.
  • two hinge devices 6 are provided which are arranged, on mutually opposite sides, at one side 5a of the lid 5 and define a rotation axis 6a for the lid itself which is substantially parallel to its side 5a.
  • each one of the hinge devices 6 comprises at least one respective supporting element 10, which is mounted so that it can slide with respect to the base 2, along the movement direction 7, and at least one fulcrum element 11, which is connected to the lid 5 and is coupled to the supporting element 10.
  • the hinge devices 6 each comprise an anchoring body 12, which is integrally fixed to the base 2, for example by means of screws 12a or by interlocking coupling.
  • the anchoring body 12 supports slidingly, along the movement direction 7, the supporting element 10 and, as shown, the elastic means 8 are conveniently provided by means of a spring 8a which is interposed between the supporting element 10 and the anchoring body 12.
  • means for the adjustment of the stroke of the supporting element 10 with respect to the anchoring body 12 along the movement direction 7 are provided by virtue of which it is possible to adjust also the distance of the lid 5 and of its gasket from the base 2, with the lid 5 in the closed position and the machine in the inactive condition.
  • the fulcrum element 11 comprises a hinge head 15, which is self-balanced and coupled to an engagement seat 16 formed in the supporting element 10.
  • the hinge head 15 has a longitudinal raised portion interlocked in the engagement seat 16, which is shaped correspondingly thereto.
  • the anchoring body 12 has a tubular portion 12b, which is extended substantially parallel to the movement direction 7 of the supporting element 10.
  • the tubular portion 12b is closed at one end, by a ring 18 which is coupled, by means of a thread, to the tubular portion 12b.
  • the spring 8a is accommodated axially in the tubular portion 12b, so as to act, with one of its ends, against the ring 18 and, with its opposite end, against a shoulder that is formed on the supporting element 10. In this manner, by unscrewing or screwing the ring 18 with respect to the tubular portion 12b it is possible to vary the elastic response of the spring 8a with respect to the movement of the supporting element 10, with respect to the anchoring body 12, along the movement direction 7.
  • the cited means for adjusting the stroke of the supporting element 10 are advantageously provided by means of a rod 20, which is extended axially inside the tubular portion 12b.
  • the rod 20 is coupled, at one end, to the supporting element 10 by means of a thread and slidingly crosses an axial opening 18a formed in the ring 18.
  • the rod 20 has a maneuvering head 21 that rests against the edge of the axial opening 18a, so that by screwing or unscrewing the rod 20 with respect to the supporting element 10, by means of the maneuvering head 21, it is possible to vary the stroke performed by the supporting element 10 with respect to the anchoring body 12 along the movement direction 7.
  • the fulcrum element 11 of each hinge device 6 comprises a rotation pivot 25 which is accommodated so that it can rotate, with one of its ends, in a rotation seat 26 that is formed substantially parallel to the side 5a of the lid 5.
  • the rotation seat 26 is formed inside a tubular profile 26a fixed to the side 5a of the lid 5.
  • the rotation pivot 25 supports rotatably a sleeve 27 which is fixed to the rotation seat 26.
  • the hinge head 15 is fixed to the end of the rotation pivot 25 that is opposite with respect to the one inserted in the rotation seat 26 and an elastic element 28 is interposed between the sleeve 27 and the hinge head 15 and contrasts elastically the relative rotation between the hinge head 15 and the sleeve 27.
  • the access opening 4 of the vacuum chamber 3 is closed and, since the hinge devices 6 are movable along the movement direction 7, the gasket 5 of the lid touches evenly all the perimeter of the access opening 4 of the vacuum chamber 3.
  • the lid 5 When vacuum is started, the lid 5 lowers evenly for a few millimeters, overriding the elastic force of the springs 8a that act on the supporting elements 10 of the hinge devices 6.
  • the lid 5 can remain, when lowered, in a completely horizontal position, facilitating, if the machine is used on a drawer, the return of the drawer itself into the corresponding container, while during vacuum start, since there is more space between the gasket of the lid 5 and the vacuum chamber, it is not necessary to exert any additional effort in order to allow the gasket to make contact with the entire perimeter of the access opening 4 of the vacuum chamber 3.
  • the invention is capable of fully achieving the intended aim and objects and in particular it is stressed that the machine according to the invention can be validly used on drawers, since the hinge devices of the lid associated therewith allow the lid to arrange itself horizontally when it is lowered onto the base, thus avoiding interference with the container that accommodates the drawer, both when the drawer is closed and in particular during its opening.
  • Another advantage of the invention is to be able to adjust the position of the supporting elements with respect to the plane of arrangement of the access opening of the vacuum chamber and more particularly of the flat horizontal surface of the base on which the lid 5 abuts. This allows, during the assembly of the machine, the arrangement of the lid according to the tolerances imposed by the materials used for the vacuum chamber and for the lid.
  • the materials used may be any according to the requirements.
