Definitions

  • the present invention essentially relates to an automatic sealing process for containers, such as cups, intended for example to contain any foodstuff.
  • It also relates to a device for carrying out this process as well as a container packaging machine which is equipped with this device.
  • These devices could consist of a rotary drum fitted with suction cups capable of gripping the lids and, after rotation of the drum, of depositing them on the cups previously filled with any commodity.
  • the present invention aims to overcome all the above constraints by providing a method and an automatic container sealing device which can use lids of any size, which are sterilized on both sides in a way efficient and without the need for complicated and expensive equipment.
  • the subject of the invention is a method of sealing containers, such as for example cups, and of the type consisting in gripping lids using suction cups integral with a drum and then releasing these lids after rotation of the drum, characterized in that after having gripped the cover, it is pressed by the action of vacuum against the wall of the drum so that the latter can heat and sterilize by thermal conduction said cover, after which it is applied , after rotation of the drum, the edge of the container against the heated and sterilized cover before it is released from the drum so as to allow at least temporary fixing of the hot and sterile cover on the edge of the container, following whereupon the cover is released from its suction cup with the container.
  • the invention also relates to a sealing device for implementing the above method, and of the type comprising a drum with which suction cups are associated connected to a vacuum source to be able to grasping the lids, characterized by a vacuum circuit arranged in facets constituting the periphery of the drum, and opening at the level of the external face of these facets, in which is embedded a heating means such as for example at least one electric heating resistance .
  • the suction cups are slidably mounted in the facets orthogonally to the plane of these, and each comprise a face in which opens a vacuum circuit and flush with the external face of the facets in the retracted position of the suction cups in the drum.
  • the external face of the facets of the drum has a hollow part receiving the head of the suction cups.
  • the suction cups are constantly stressed by a spring in the retracted position in the facets of the drum and are controlled by a rack pusher meshing with a pinion and arranged in the center of the drum.
  • the vacuum circuit arranged in the facets of the drum comprises a plurality of conduits opening on the external face of the facets around the housing receiving the suction cup and connected to a collector connected to a source of vacuum.
  • This device can advantageously be incorporated in a container packaging machine comprising in particular a system for filling the containers upstream of the drum, a system for sealing the lids downstream of this drum, and a system for pushing the containers against this drum and arranged in below it.
  • an automatic packaging machine for containers or cups R conveyed by a conveyor (not shown) and passing successively below a filling station 1, a sealing station 2 and , optionally, a heat-sealing station 3 for the lids 4 on the containers R, which lids are for example stacked in a hopper or the like 5 situated above the station 2.
  • the sealing station 2 is constituted by a device which is the subject of the present invention and will be described in detail below.
  • a drum 6 whose periphery is constituted by a plurality of facets 7 in each of which is arranged a vacuum circuit opening on the external face 7a of facets 7.
  • a heating means is embedded consisting by one or more electric heating resistors 8.
  • each facet 7 is constituted by a plurality of conduits 9 opening at the level of the external face 7a of the facets and connected via a collector 10 to a source that is not shown.
  • each facet 7 is mounted orthogonally sliding a suction cup 11 whose head 12 can, in the retracted position of said suction cup, be received in a hollow part or housing 13 formed in the external face 7a of the facet 7. More precisely and as as can be seen in FIG. 2, the face 12a of the head 12 of the suction cup 11 is flush with the external surface 7a of the facet 7 with which the suction cup is associated, when said suction cup is in the retracted position in the facet.
  • suction cups 11 are constantly stressed in the retracted position by means of a return means, such as for example a spring 14 interposed between the underside 15 of the facet and a stop element 16 secured to a rod or analog 17 constituting the rear part of the suction cup 11.
  • a return means such as for example a spring 14 interposed between the underside 15 of the facet and a stop element 16 secured to a rod or analog 17 constituting the rear part of the suction cup 11.
  • Each suction cup 11 comprises a vacuum circuit essentially constituted by one or more conduits 18 opening towards the external face 12a of the heads 12 of suction cup and connected to a vacuum source (not shown) via, for example, a collector 18a.
  • the movement of the suction cup 11 relative to the facet 7 is, according to the embodiment shown, controlled by a rack plunger 19 shown diagrammatically in FIG. 1 and meshing with a pinion 20.
  • the rotation drive of this pinion by any means allows an alternative movement of the pusher 19 which acts on the rod 17 carrying the suction cup 11, as is clearly visible in FIG. 1.
  • the suction cup 11 is pushed out of the plane of the facet 7 with which it is associated, thanks to the plunger 19 which is arranged substantially in the center of the drum 6.
  • the head 12 of the suction cup 11 will be able to grasp, by action of the vacuum in the pipe 18, a cover 4 in the hopper 5.
  • the pusher 19 is then actuated downwards, and thanks to the return spring 14, the head 12 of the suction cup 11 retaining a cover 4 will be housed in the hollow part 13 of the facet 7. Therefore, the cover 4 will be in the same plane as that of the external face 7a of the facet 7 and will be intimately pressed against this external face by action of the vacuum in the conduits 9.
  • the drum 6 can then start its rotation as seen in Figure 3, it being understood that, during this rotation, the facet 7 will be heated by the electrical resistors 18 embedded in said facet and thus allowing heating and sterilization by thermal conduction on both sides of the cover 4, at a temperature close to 170 ° C. It will be emphasized here that, thanks to this method, an ideal and perfect sterilization of the entire cover is obtained, which may have a any dimension depending on the container to be closed, since there is no need to maintain it laterally since it is perfectly maintained during rotation of the drum 6 by suction against the facets of this drum.
  • the sterile and hot cover 4 will be fixed, in the manner of a bonding, on the edge 22 of the container R, after which the vacuum is broken in the conduits 18 and 9, so that the cover 4 is released from the drum, it being understood that the pushing system 21 lowers the container R which can then reach the heat-sealing station 3 so as to perfect the obturation.
  • heat sealing is in no way compulsory from the moment when, as described above, a relatively solid fixing of the cover 4 on the edge 22 of the container R can already be obtained at the level the sealing station 2.
  • FIGS. 1, 3 and 4 There is shown diagrammatically at 23 in FIGS. 1, 3 and 4 a grid or the like possibly allowing a distribution of sterile air opposite the drum 6 and upstream of this drum to keep the containers R filled and not closed, in a sterile atmosphere. , but such a means is in no way mandatory and could perfectly well be omitted without departing from the scope of the invention.
  • the means 21 for pushing the container R against the facets of the drum can take any shape, and this drum can be incorporated in any machine of containers to be filled with an equally arbitrary product.
