Definitions

  • the present invention relates to a method and an apparatus for fully-automatically carrying out the filling and vacuum sealing of pairs of opposite envelope-type or bag-type containers fed in the form of a continuous web to filling stations.
  • envelopes of flexible plastic material that are directly heat-sealable or envelopes of aluminium foil made heat-sealable by the presence of a thin coating of plastic material.
  • EP-A-487 788 discloses a method and apparatus according to the preambles of appended claims 1 and 2 in which a device is inserted apt to receive within a chamber that can be hermetically closed, a limited number of containers previously filled with the products whereafter the vacuum is created in said chamber and the container opening heat-sealed in the chamber itself, as defined in claims 1 and 2.
  • the webs of paired containers facing each other that can be used in the filling and vacuum-sealing method according to the present invention can consist of any known type of paired containers, i.e. bags or simple envelopes, envelopes with bellows-like bottom, envelopes with two side bellows, or envelopes with side bellows and simplified bottom bellows to allow vertical self-support of the container.
  • Envelopes with side bellows are preferred because they allow a greater automatic opening out of the flaps of the upper container opening on filling.
  • the containers are supplied by firms specialised in manufacturing bags in the form of a continuous web of paired containers having upper openings facing each other and wound up in the form of a bobbin or concertina-folded in packaging boxes.
  • This feature makes the production by the user customer easier because the latter must only attend to carrying out the final hermetic seal for closing the container after having filled the same.
  • the final controls are reduced in favour of a more practical operation. From the point of view of surface contamination too, the closed bag is more reliable than the material on a reel.
  • Fig. 1 the apparatus altogether identified by A, is in its general features of known type.
  • the apparatus is fed with a web 2 of paired containers 3, 3' of flexible material joined to each other by an intermediate strip 20 and concertina-folded inside a packaging box 5, as supplied from the manufacturer of the containers.
  • the apparatus is provided with a rod-shaped support 6 descending gradually until close to the packaging box 5 where is centred the strip 20 that keeps in a connected relationship the web of paired containers 3, 3' folded up in the box itself (see also Figs. 2 and 3).
  • the containers 3, 3' moved by a drive or transport unit 10 are arranged on either side of support 6 which, downstream, at position 8, progressively widens out until it becomes, at the transport unit 10, a track of practically the same transverse width as strip 20.
  • the transport unit 10 is preferably made up of an upper roller 11 provided with linear jutting out elements opposite which are the corresponding cavities of an underlying nip-roller so as to pluck the material of the union strip 20 as shown under reference 14 in Figs 2 and 3, thereby achieving a positive and regular forward movement of the containers 3-3'.
  • the containers reach the filling stations 25 with the flaps of their respective openings that already having been widened out upstream through the action of opening-out members 24 of a known type.
  • the insertion of an additional work station is provided, which station, identified by 30 in Fig. 1, usefully completes the task of the existent apparatus in accordance with the intended object.
  • the additional station 30 shown only schematically, consists of a chamber 32 which can be opened and re-closed with a hermetic-seal lid 34 and in which a vacuum condition can be created.
  • Chamber 30 is provided with a relatively limited capacity, i.e. 1 to 4 pairs of containers at the most, depending on their transverse size, so as to limit the creation of the vacuum condition within conveniently reduced periods of time, and it is internally provided with one or more pairs of thermoelectric jaws to operate the hermetic sealing of the filled pairs of containers inside which, as desired, the products remain protected under the condition of a very limited presence of air.
  • the lid 34 is removed and a pliers device draws the sealed envelopes out of the chamber and introduces therein other just filled envelopes.
  • the pairs of already sealed envelopes reach the end station 40 where the union strip 20 can be recovered and the individual or paired envelopes fall into the respective packaging boxes for despatch.
  • the containers for use in this apparatus can be of various types, among which there are those provided with side bellows as shown in Fig. 2, or those of the vertical self-supporting type, as shown in Fig. 3 or in Fig. 4.
  • the side ends of the web can be pressed by heatable jaws in order to perform, at the bottom of each container, the conjunction of all heat-sealable facing surfaces, thereby forming two inclined sealing connections 23, 23' that, starting from the sealing closure 22 of the bottom of the final bag, connect with the side sealing closures 21, 21' of same so as to form a bellows in replacement of known bellows of curved conformation.
  • the four sides of the bottom have a sealing closure 22 involving the whole perimeter of the bottom itself and the lower edge of the four sealing closures 21 of the upright walls so that the bottom rest surface essentially corresponds to the whole surface of the bottom itself.
