Definitions

  • This invention relates to a machine for forming filter-bags with infusion products.
  • infusion products means products such as tea, coffee, camomile (in powder, granules, or leaves).
  • the machine according to the invention is used for forming filter-bags of the single-lobed or double-lobed type, or in any case on filter-bags with a flat extension.
  • two-lobed filter-bags they comprise a single length of filter paper defining two separate and closed chambers. Each chamber contains a dose of infusion product.
  • the two chambers are folded towards each other forming a single upper end (in the shape of an upturned "V") and a bottom end in the shape of a "W.
  • the filter-bag may be equipped with a thread for association with a gripping tag.
  • That patent document describes a machine structured along a forming and feeding line on which are positioned:
  • - a station designed to close the web on itself, wrap the doses of product and, subsequently, longitudinally join the web;
  • a station for folding individual pieces of filter paper with double chamber - a carousel equipped with radially protruding grippers, positioned beneath the folding station and configured to receive individual pieces of folded filter paper; the carousel, moved stepwise about a horizontal axis, moves each piece of filter paper in the proximity of stations arranged one after another to associate to the piece of filter paper a thread, suitably wrapped around the piece of filter paper, and a tag in turn associated with the thread.
  • the carousel transfers the filter-bag thus formed to a station for preparing and packaging groups of filter-bags comprising units for orientation of the filter-bags, units for stacking and transferring of the filter- bags stacked in packages (of particular interest in this specification).
  • the orientation unit (shown in patent document EP762973) comprises (see Figure 1 ) a drum T, positioned alongside the carousel GS, comprising a plurality of housing pockets T1 , arranged circumferentially and each designed to house and retain by interference a filter-bag SF whilst the drum T rotates in a stepwise fashion and a transporting element OT which picks up by a gripper PZ of the carousel GS, and carries (with substantially rectilinear motion) on the pocket of the drum, the filter-bag.
  • the drum T moved stepwise about an axis parallel to the axis of the carousel, has, precisely, the duty of receiving, rotating (orienting), and releasing the filter-bags SF inside the stacking station SI for preparing, transferring and housing groups (in a predetermined number) of filter-bags
  • the stacking and packaging units of the station SI comprise:
  • a plate PT defining a bottom base inside the tubular conduit; the plate is movable, in both directions, along the conduit and in a synchronised fashion with the arrival of the individual filter-bags from the opening of the conduit and in such a way as to form a stack of filter-bags feeding towards the bottom of the tubular conduit;
  • a gripper PM movable radially and longitudinally relative to the tubular conduit and configured to retain the stack formed between the top and bottom of the stack (simultaneously with a disengagement of the bottom plate); the gripper is provided with sliding means for transferring the stack beyond the bottom of the tubular conduit and towards a unit for transferring the stack positioned, in a receiving position, coaxial with the tubular conduit and below the latter.
  • the transfer unit has a housing body composed of three walls (two side and one bottom) forming a U-shaped housing for receiving the stack of filter-bags; a side wall is movable towards and away from the other side wall for retaining or releasing the stack of filter-bags.
  • the body is associated with an articulated arm to a motor-driven shaft and rotates about an axis parallel to the axis of the drum to allow a rotation of the body from a position for receiving the stack to a position for releasing the stack inside a box set up in advance and vice versa.
  • the structure of the station for preparing and packaging groups of filter-bags comprise a multiplicity of components forming the operating units which must be synchronised in the operational movements through a large number of kinematic systems which, in effect, make this portion of the machine extremely complex and bulky.
  • this end section of the machine must maintain high operating speeds as a function of a high speed for feeding the filter-bags with respect to the speed, more constant and step by step, of the remaining stations designed to form the individual filter-bags.
  • Patent documents WO2012/1 17308, US2002/139086 and WO2007/138471 describe corresponding further solutions of structures for stacking groups of filter-bags formed and fed by a carousel or drum for unloading filter-bags formed by the preceding stations.
  • the aim of this invention is therefore to provide a machine for forming filter-bags for infusion products which is able to simplify the operations and the operational components present in the station for preparing and packaging groups of filter-bags.
  • the aim of this invention to provide a machine for forming filter-bags for infusion products which is able to perform in a single operation both the orientation and the packaging of the stack of bags and maintain a high production speed.
  • FIG. 1 illustrates a schematic front view, with some parts cut away to better illustrate others, of a part of the machine for forming filter-bags for infusion products of known type and in particular a carousel for forming filter-bags and a part of a station for preparing and packaging filter-bags;
  • FIG. 2 illustrates a schematic front view, with some parts cut away to better illustrate others, of a part of the machine, according to this invention, and in particular a carousel for forming filter-bags and a part of a station for preparing and packaging filter-bags;
  • FIG. 3 and 4 illustrate schematic front views, with some parts cut away to better illustrate others, of another part of the preparing and packaging station of the machine according to the invention, in particular a unit for transferring groups of filter-bags, in two different operating positions;
  • FIG. 5 illustrates a side view, with some parts in cross section and others cut away to better illustrate some details, of the transfer unit of Figures 3 and 4;
  • FIG. 6 illustrates a schematic front view of a detail of movement elements of the transfer unit of Figure 5.
  • infusion products means products such as tea, coffee, camomile (in powder, granules, or leaves).
  • the filter-bag 1 formed by a machine according to the invention may be of the two-lobed type, that is to say, having two chambers folded towards each other forming a top end 1 a (with the shape of an upturned "V") and a bottom end 1 b with the shape of a "W.
  • the machine 100 comprises a transporting element 2 configured for picking up, transporting and releasing individual filter-bags 1 from a operating station 3 for forming the filter-bags 1 , rotating about a first axis X3, to a station 4 for preparing and packaging groups G of filter-bags 1 formed.
  • the operating station 3 is a rotary stepwise carousel, having a plurality of grippers 3a arranged radially on the carousel.

  • This dual function of the transfer unit actually increases the operational potential of the station, since the orientation is obtained on the entire group of stacked filter-bags rather than the single orientation obtained with the traditional solutions.
  • the synchronised movement structure is grouped together in a reduced size and obtains three different movements all synchronised with each other thanks to the system with three coaxial shafts assisted by the pair of conical torques present in the flange. This system considerably reduces the overall dimensions of the unit, whilst maintaining a high level of operational precision.
