Definitions

  • the present invention relates to a vacuum sealing machine. More specifically, the present invention relates to a vacuum sealing machine of the type comprising a base and a closure element which is intended to be closed on the base in order to retain a flexible container in a zone for generating the reduced pressure and/or a sealing device.
  • such machines comprise a main structure which is formed by a base and a cover, which is hinged to the base and which is closed on the base. There is further defined in the base a cavity in which an open edge of the packing is positioned. This cavity is connected to a vacuum pump which allows air to be extracted from the packing through the above-mentioned open edge.
  • the packing is sealed, typically by welding the packing at the open edge by means of a heating element.
  • the known machines In order to suitably retain the packing during the air intake and sealing operations, the known machines typically have a mechanism for locking the cover which is capable of retaining it in a position closed on the base.
  • the technical problem addressed by the present invention is therefore to provide a vacuum sealing machine which is structurally and functionally configured to at least partially overcome one or more of the disadvantages set out with reference to the cited prior art.
  • an object of the present invention is to provide a vacuum sealing machine which can be locked by means of a mechanism which can be actuated with a single hand.
  • Another object of the present invention is to provide a vacuum sealing machine which is provided with a locking mechanism which is resistant and capable of a long service-life.
  • a vacuum sealing machine which comprises a base, which is preferably intended for receiving a vacuum device and a sealing device, and a closure element which is configured so as to be closed on the base.
  • the closure element when closed on the base, it allows a portion of a flexible container to be retained, for example, a bag, for the vacuum packing.
  • the machine further preferably comprises a locking device which is configured to retain the closure element in a position closed on the base.
  • the closure element comprises a handle which is movable between a first operating position and a second operating position.
  • the locking device can preferably be switched between a locking condition, in which a movement of the closure element from the position closed on the base is prevented, and an unlocking position, in which this movement is allowed, by means of a movement of the handle from the first operating position to the second operating position.
  • the user may advantageously act on the handle both in order to close the closure element and to lock it on the base by means of suitable movement.
  • the vacuum sealing machine comprises a movement conversion mechanism which is operatively connected to the handle and which is configured so as to convert the movement of the handle into the switching action of the locking device from the unlocking condition to the locking condition and/or vice versa.
  • the movement conversion mechanism is received in the closure element.
  • the conversion mechanism is preferably mechanical but may also be of the electromechanical type.
  • the handle is supported, preferably rotatably, on the closure element. In this manner, it is possible to effectively combine the closure of the closure element with the movement of the handle.
  • the locking device comprises at least one movable pin which can be engaged in a respective seat.
  • the movable pin or pins and the seat or seats are arranged on the closure element and on the base, respectively, or vice versa.
  • the movement conversion mechanism is configured so as to convert the movement of the handle into the movement of the movable pin so as to be engaged or disengaged in/from the seat.
  • this movement can be defined by a rotation of the handle itself.
  • the movement conversion mechanism is configured so that, when the handle is moved downwards, the locking device is switched into an unlocking position. This advantageously allows the closure movement of the closure element to be combined with the locking thereof.
  • the closure element is hinged to the base.
  • the movement conversion mechanism comprises a first lever arm which is fixedly joined to the handle and a second lever arm which is fixedly joined to the movable pin.
  • the first lever arm and second lever arm are pivoted on the closure element at different positions in such a manner that the rotation of the first arm brings about a rotation in the opposite direction of the second lever arm. This allows a suitable association of the movement of the pin with that of the handle, with a solid and reliable structure.
  • the movement conversion mechanism is configured in such a manner that, following the handle being lowered, the movable pin is withdrawn from a cavity which is defined in the closure element and inside which the movable pin is received when the locking device is in an unlocking condition.
  • This characteristic allows suitable protection of the movable pin and allows it to be made available only when the handle is lowered.
  • the first lever arm and the second lever arm are pivoted about respective rotation axes which are parallel with each other.
  • the handle has an elongate form.
  • the axes are parallel with a longitudinal extent direction of the handle.
  • first lever arm and the second lever arm are connected by means of an additional pin and a slot, the additional pin and the slot being formed on the first lever arm and on the second lever arm, respectively, or vice versa.
  • the handle extends between opposite ends of the closure element.
  • the handle extends over the entire extent of the closure element in the direction defined by the hinging axis of the closure element on the base.
  • a vacuum sealing machine according to the present invention is generally designated 100.
  • the vacuum sealing machine 100 comprises a base 1 which is configured so as to be able to receive a vacuum device 11 and a sealing device 12.
  • the Figures particularly show only a cavity 11A of the vacuum device 11, in which an open end of a vacuum bag which is not illustrated in the Figures can be arranged and through which the air is drawn in from the bag in order to produce the reduced pressure required to pack a product present inside the bag.
  • the vacuum device 11 may be formed by any device suitable for this purpose.
  • heating element 12A which serves the purpose of joining two edges of the bag in order to obtain the sealing thereof is also visible in this case in the Figures.
  • sealing device 12 may also be provided.
  • the base 1 is associated with a closure element 2 which is configured so as to be closed on the base 1 and to retain a portion of a flexible container, such as, for example, the above-mentioned bag, for the vacuum packing of a product, for example, a food product.
  • a closure element 2 is hinged to the base 1 and can be closed thereon by means of a rotational movement towards the base about the hinging axis thereof.
  • the vacuum device 11 and the sealing device 12 can advantageously be configured to operate on the flexible container when it is retained between the base 1 and the closure element 2.
  • the machine 100 comprises a locking device 3 which is configured to retain the closure element 2 in a position closed on the base 1.
  • the locking device 3 preferably comprises at least one movable pin 30 which can be engaged in a respective seat 31, the movable pin 30 and the seat 31 being arranged on the closure element 2 and on the base 1, respectively, or vice versa.
  • the movable pin 30 and the seat 31 being arranged on the closure element 2 and on the base 1, respectively, or vice versa.
  • the closure element 2 comprises a handle 20 which is movable between a first operating position and a second operating position.
  • the handle is supported on the closure element, preferably being rotatably connected thereto.
  • the locking device 3 can advantageously be switched between a locking condition, in which a movement of the closure element 2 from the position closed on the base 1 is prevented, and an unlocking condition, in which this movement is allowed.
  • this switching is brought about by means of a movement of the handle 20 from the first operating position, which is illustrated by way of example in Figures 1 and 3 , to the second operating position thereof, which is instead illustrated in Figures 2 and 4 .
  • the machine preferably comprises a movement conversion mechanism 4 which is operatively connected to the handle 20 and configured so as to convert the movement of the handle into the switching action of the locking device 3 described above, that is to say, to be switched from the unlocking condition to the locking condition, and/or vice versa.
  • a movement conversion mechanism 4 which is operatively connected to the handle 20 and configured so as to convert the movement of the handle into the switching action of the locking device 3 described above, that is to say, to be switched from the unlocking condition to the locking condition, and/or vice versa.
  • the movement conversion mechanism 4 may comprise a first lever arm 41 which is fixedly joined to the handle 20 and a second lever arm 42 which is fixedly joined to the movable pin 30.
  • first lever arm and the second lever arm are pivoted at the closure element 2 in different positions, which are designated A and B in Figure 2A , in such a manner that the rotation of the first arm 41 brings about a rotation in the opposite direction of the second lever arm 42.
  • the first and second lever arms may advantageously be pivoted about respective mutually parallel rotation axes, with the axes parallel with a longitudinal extent direction of the handle.
  • the handle may have an elongate form.
  • the hinging location A of the first arm 41 is arranged in an upper position with respect to the hinging location B of the second arm 42.
  • the hinging location A of the first arm 41 coincides with the rotation axis of the handle 20.
  • first and second lever arms may be connected by means of an additional pin 41A and a slot 42A which are illustrated in Figure 2A , the additional pin and the slot being formed on the first lever arm 41 and on the second lever arm 42, respectively, or vice versa.
  • the movement conversion mechanism 4 is configured so as to convert the movement of the handle 20, where applicable the rotation thereof, into a movement of the movable pin 30 so as to allow the pin to be engaged in or disengaged from the seat 31.
  • the movement conversion mechanism 4 is configured so that, when the handle is moved downwards, where applicable by means of the rotation thereof, the locking device 3 is switched to an unlocking position.
  • the movement conversion mechanism 4 is configured so as to convert a rotation of the handle 20 into the movement of the movable pin 30.
  • the handle 20 extends between opposite ends of the closure element, the ends being relative to the direction defined by the hinging axis of the closure element 2 on the base 1.
  • the handle 20 extends over the entire extent of the closure element 2 in the direction defined by the above-mentioned hinging axis.
  • the covering element 2 has lower extensions 21 which preferably extend downwards from a main lower surface of the covering element and inside which the movable pin 30 may be received when in the unlocking position.
  • the movement conversion mechanism 4 may preferably be partially received in the lower extensions 21.
  • the second arm 42 is partially received in the extension 21.
  • the lower extensions 21 can be received inside housings 31A, in which the seats 31 for the pins 30 are defined.
  • the movement of the above-mentioned pin may therefore advantageously be such that the pin 30 itself is withdrawn from a cavity which is defined in the closure element 2, where applicable defined by the lower extension 21, and inside which the movable pin 30 is received when the locking device 3 is in an unlocking condition.
  • the invention thereby provides a vacuum sealing machine which solves the problem proposed, affording a number of advantages, particularly including the possibility of carrying out the locking of the closure element by means of a simple operation which can be carried out with a single hand.
