Definitions

  • the present invention refers to a vertical packaging machine, with quick format change and its operating method.
  • the invention refers to a vertical machine of the defined type as cartoning machines or case packers, wherein a die - cut product is formed into a box and wherein the vertical box is sustained by gripping means and filled on a carousel; the format (size) change of boxes packaged on the machine can be carried out rapidly, by adapting the packaging means to sizes of the box to be filled.
  • Packaging machines, cartoning machines or case packers are known, presenting means for the adaptation to sizes of the box to be used for packaging.

  • Box sizes could be various and, for this reason, known machines have means for changing the box format and treating different boxes.
  • Object of the present invention is to solve afore discussed problems and to provide an automatic packaging machine allowing a rapid format change, that is a quick adaptation to boxes of different sizes, at the same time guaranteeing the quickness of packaging operations. Further object is to provide a vertical packaging machine for cartons or bags that allows also an easy control of number of pieces fed to the box or bag in addition to the format change.
  • Such a machine has a supporting structure for means for carrying boxes or similar packages, one or more hoppers or others similar means for feeding product to the machine and at least one plurality of containers disposed between the hoppers and boxes (or other packages) to hold temporarily the product before its feeding to the boxes; these containers being realized with several portions in order to be able to change the dimensions of the output opening to adapt the latter to the input openings of the boxes, at least in one dimension, usually the width.
  • the machine comprises two series of containers: a plurality of first containers to receive the product from dosing means and holding it temporarily and a plurality of second containers to transfer the product from the first containers to the boxes or other packages, also the second containers being composed of several portions and the position of said portions being changeable by said machine to change the width and depth of said containers as a function of the box width and depth.
  • Machine containers comprise kinematic mechanisms to modify the reciprocal position of the portions of containers and then the dimensions thereof, or at least of their output opening; kinematic mechanisms are operated by the machine itself when a format change is necessary. More in particular the first containers, receiving the product from hoppers by means of dosing devices, are assembled on chains sliding along fixed guides, and at least two chains are movable in opposite directions to operate the kinematic mechanisms to change the container dimensions. A similar system for adjusting the distance between two elements is known for the distance adjustment between gripping fingers of boxes only.

More in detail, the adjusting roller 25D is integral with a rail 54, being able to slide perpendicularly with respect to the carrying plate 51, in the direction shown by the arrow 53. Through the adjusting roller 25D the adjustment of the back rest happens, based on the depth of the box format 16. In addition, the back rest tray acts also as an ejector thereby allowing the box to be pushed towards the operative station 41 or the reject station 44.
  • This tray in order to operate correctly, provides for a rest affecting a great surface that changes with the format of the box 18 and placed on the box wall facing towards the inside of the carousel. Because of the great height variability of boxes 18, in the shown embodiment a swinging rest tray is selected, driven by a mechanical lever that takes motion from the element 25E, the latter moving vertically during height adjustment of the box format. In this way, as the box height increases, the tray 55 increases its tilt with respect to the horizontal lie it takes for the minimum format, thereby increasing with this movement the vertical extension of the rest surface of the box.
  • the adjusting elements 25E are C-shaped and they are inserted into appropriate means of the packaging machine 31, better defined later, able to handle them vertically.
  • the adjusting means 25 are integral with rails 30 that could slide in parallel, according to the direction indicated by the arrow 56, with the activating element 28 and the carrying plate 51.
  • the height adjustment of the package 16 happens through the adjusting element 25E, so that to be able to position the second feeding container 21 just over the opening of the boxes 16, in order to optimize the product transfer thereon.
  • the gripping means 33 that is the two clamp elements 33A and 33B, are fixed to rails 30.
  • the rails 30 are arranged to be integral with the width changes of the second container 21.
  • the L-shaped portion 17B of the second feeding container 21 is subjected to displacement with respect to the L-shaped portion 18B, through the activating elements 28 driven by the previously described adjusting roller 25B, the same displacement is transferred in sequence to rails 30 and to clamp elements 33A and 33B of the gripping means 33.
  • the packaging machine 31 has a fixed guide 57A, shaped like a C, defining a path for the adjusting roller 57A.
  • the fixed guide 57A has a slope 57.1A coinciding with the approach of the second feeding container 21 towards the box 16 and the product unload therein.
  • the path of the adjusting roller 25A is always the same in every operative cycle of the packaging machine 31.
  • the packaging machine has the guides 57B and 57C, vertically movable and shaped like a C, adapted to handle the adjusting rollers 25B and 25C, respectively.
  • a motor assembly 59.1A handles a group of warms 58.1A on which the guides 57B screw.
  • a further motor assembly 59.2A handles a group of warms 58.2A on which the guide 57C screws.
  • the packaging machine has the guide 57D, vertically movable and shaped like a U, adapted to handle the adjusting roller 25D.
  • the guide 57D is formed by two connecting flexible elements 57.1D and 57.2D or, as shown in figures, conveniently shaped so that to slide one with respect to the other, adapted to guarantee the path continuity of the adjusting roller 57D for all possible dimensions of the guide 57D.
  • the guide 57D is provided with ejecting means 60 and 61 ( figure 16 ) of the boxes 16 from the path 34.
  • the ejecting means 60 and 61 are shaped to intercept the path of the adjusting roller 57D, so that to handle the ejecting tray 55 towards the box 16 and to release the same box 16 from the gripping means 33.
  • the ejecting means 60 and 61 are shaped like a lever, movable around the fulcra 60A and 61 A, respectively, and they are shown in their interference position with the path 32.
  • Appropriate means, not shown, are adapted to handle the ejecting means 60 and 61, that is their rotation around the fulcra 60A and 61A, respectively, so that to interfere with the path 32 of the adjusting rollers 25D or to avoid the passage thereof.
  • the activation of the ejecting means 60 pushes the box 16 towards the reject station 44 whereas the activation of the ejecting means 61 pushes the box 16 towards the operative station 41.
  • the packaging machine 31 has means adapted to handle vertically the slide flange 57E.
  • said means are composed of the motor assembly 59B and are adapted to activate the group of warms 58B.
  • the slide flange 57E acts also as slide plane that supports the boxes 16 at the bottom.
  • Electrical or pneumatic drives are used to handle the rollers 13 and to drive consequently the opening of the shutters 9, 29 so that to allow the product to pass from the feeding containers 1, 21 to the level below in points designed at the path end.
