Definitions

  • the present invention relates to a device intended to facilitate filling of tubular containers, specially when it is intended to can in the said container solid pieces such as blocks or tablets of a comparatively large size.
  • canning of such blocks is generally performed by means of covers made of cellophane, plastics or other material of a light nature, which do not afford to the product the necessary protection against mechanical strains such as blows, pressures, friction and the like fatally damaging the said product, breaking and crumbling it such that it losses its appearance.
  • the document DE-C-675 656 refers to a container filling device comprising a movable stop associated with a first opening of the container and a pusher faced to the second opening of the container and connected with driving means to push a row of product blocks put between the pusher and the container Into this container and until abutting with the movable stop.
  • the subject of the invention is indeed to facilitate canning and preparing pieces of the above said features, such that they are able to reach the user public in a good condition and with its whole shape, such that its appearance is not impaired.
  • the device for forming and filling tubular containers comprises, besides the fact that it may comprise a conventional cutting and stamping off station, a container filling device including a movable stop associated with a first opening of the container and a pusher faced to the second opening of the container and connected with driving means to push a row of product blocks put between the pusher and the container into this container and until abutting with the movable stop, and it is characterized it that it is made up of: an endless conveyer guided between two direction change points thus forming at least one essentially straight working run between these points and driven stepwise in one working direction; a plurality of pairs of nippers mounted on the conveyer at regularly spaced points of its length, each pair of nippers having two legs fast on the outer surface of the endless conveyer at longitudinally spaced points thereof, such that the said nippers assume an open, container releasing, position at the places where the conveyer performs
  • the nippers of the conveyer can be present in a number suitable for picking up, and subsequently releasing, one or more tubes or containers at a time.
  • the filling stations will also be, as it is obvious, several in number and arranged along the conveyer length.
  • the method starts from a sheet of the features described in the Spanish Utility Model N ° 242 532, which is rolled up over itself to define a tubular body 1 with its borders 2 overlapped and stuck by respective heat sensitive adhesion bands 3 which are disposed at the inside and adjacent the container ends.
  • This body will, eventually, have a tearing band 4 for opening the container, and a small window 5 covered by a transparent sheet 6 to look at the inside.
  • the thus constituted tubular body is placed in front of a preferably movable stop 7, and the blocks or tablets 8 to be canned are inserted therein through the opposite opening, for example by means of a pusher or the like 9 which is suitably operated.
  • a pusher or the like 9 which is suitably operated.
  • the blocks Once the blocks have been inserted, it is proceeded with applying lids 10 at both ends of the container, which may be, indifferently, a shape of a flat disc or the indicated shape of a shallow pan, with its wings juxtaposed to the terminal edges of the container, after which the container will be completed and closed by a flanging 11, enclosing into it the canned product 8.
  • a device suitable for filling and closing the containers is represented in diagrammatic form in the Figure 6 and will complete an installation which is to comprise stations, of a conventional composition, for cutting and stamping off the sheets 1.
  • the said device comprises of an endless conveyer 12 formed of ring closed flexible band of any suitable conventional construction which is mounted taught between two direction changing rollers or the like 13 such that it forms two straight upper and lower runs respectively 12a,12b, with the rollers adapted to rotate about respective central axis 13a and connected with suitable well known operating means.
  • one axis 13a can be mounted on lengthwise adjustable journals, not shown, to place the conveyer band under a suitable working tension, and the other shaft 13a, of fixed position, can be connected to a conventional speed reducing motor gear to drive the ensemble of the conveyer in the direction shown by the arrows in Figure 6.
  • the conveyer 12 has mounted on its outer surface (as regards the closed ring) suitable pairs of nippers 14, disposed at regularly spaced positions along the length of the conveyer band.
  • Each said pair of nippers is formed of two legs 14a,14b mounted at a short mutual longitudinal distance on the band, and the mutually faced sides of each leg in a pair of nippers are formed with complementary surfaces to form, together, a housing for a tubular container 1.
  • the legs are conformed to receive containers 1 of a cylindrical shape, but it is obvious that the described nippers could be devised to handle containers 1 having whatever different shape in cross section. It is also possible to devise the legs 14a,14b such that they, or at least a portion thereof could by substituted by legs, or parts of leg, defining a housing for differently shaped containers 1.
  • each pair of nippers 14 are mounted fast, independently of one another, on the surface of the band of the conveyer 12, such that the nippers 14c,14d,14e that any time are located on a straight run, for example 12a, of the conveyer 12 conform, with the complementary faces of their legs 14a,14b, a housing with the cross section dimensions suitable to grasp in fixed relation a corresponding tubular container 1c,1d,1e.
  • the conveyer 12 is driven such that it rotates in the direction indicated by the arrows in Figure 6.
  • this drive is performed in a stepwise manner such that the several nippers remain stationary at the positions shown in the Figure 6 for a time suitable for the several operations to be carried about on the containers to take place as desired, and when these operations are finished, the ensemble of the conveyer is moved forward a length corresponding to the peripheral pitch of the pairs of nippers 14 on the conveyer band and these latter are advanced one pitch along the series of positions or stations indicated by the nippers 14, 14c, 14d and 14e.
  • the container in the station 1 is moved to the station 1c, the one in station 1c to the station 1d, and so forth.
  • load and discharge station 14 filling station 14c, lid placing station 14d and lid closing station 14e.
  • an empty container 1 is pushed by a conventional means from the outer position shown up to between the two legs 14a,14b of the nipper in position 14, at the same time pushing out of the conveyer a filled and closed container, not shown, which has reached this station after several step motions along the lower run 12b of the conveyer.
  • a similar pusher device can discharge a completed container at the open position which the nippers 14 assume at the opposite end of the conveyer. Otherwise, although not as much efficiently, one or both operations can be performed by hand on one or both terminal stations described.
  • a one step advance motion is performed and the thus inserted tubular container 1 comes to the next station or filling station 14c comprising the movable stop 7 and pusher 9 foreseen in Figure 2, according to which the blocks 8 are inserted in the tubular bodies 1.
  • a further step motion carries the tubular container 1d, with its lids fitted, in front of the last station 14e in which several conventional flanging mechanisms 16 act upon the edges of the tubular body, and eventually also on those of the lids 10, such that the tubular body or container 1 becomes thoroughly closed and with the product 8 housed in its inside, as previously indicated.
  • a further step motion would carry the thus completed container 1e to the discharge station located at the right side end of the conveyer according to the described alternative embodiment, or the said completed container will come, after a number of step advancing motions, to the load and discharge station 14 as described above.
  • these nippers may be arranged over the conveyer 12 forming groups for every one of these steps, such that they act picking up and releasing, respectively at the conveyer beginning and end, a suitable number of containers at a time to be handled simultaneously one group at a time, in which case the handling stations will as well be multiple at each filling and closing station.
