Definitions

  • the present invention relates to a method and unit for transferring a product on an intermittent packing machine.
  • the present invention may be used to advantage in an intermittent automatic cigarette packing machine, to which the following description refers purely by way of example.
  • Cigarette packing machines are traditionally “intermittent” machines, i.e. the packing conveyors are operated intermittently (or “in steps"), in which a pause, during which the packing conveyor pockets are stationary, alternates cyclically with a conveying step, during which the packing conveyor pockets advance a given distance.
  • a pause during which the packing conveyor pockets are stationary, alternates cyclically with a conveying step, during which the packing conveyor pockets advance a given distance.
  • groups of cigarettes are transferred between two successive packing conveyors during the pause.
  • An intermittent cigarette packing machine normally comprises a number of packing wheels with peripheral pockets for receiving and conveying groups of cigarettes.
  • the groups of cigarettes for packing are fed gradually through the packing machine, and are transferred from one packing wheel to the next at a transfer station defined at the point of tangency between the two wheels.
  • a transfer station defined at the point of tangency between the two wheels.
  • two pockets of the two packing wheels are aligned (transversely or longitudinally) and positioned facing each other during the pause between one conveying step and the next, to allow a push member to transfer a group of cigarettes from the releasing pocket to the receiving pocket.
  • each packing wheel In all known intermittent packing machines, the pockets of each packing wheel are connected rigidly to, and so perform no movement with respect to, the packing wheel.
  • the packing wheels are obviously so designed and located that a releasing pocket is always aligned facing the corresponding receiving pocket at the transfer stations, to allow transfer of a group of cigarettes from one pocket to the other.
  • packing wheels of the above type are extremely rigid in terms of positioning, and also have the drawback of entailing considerable design complications to transfer more than one group of cigarettes at a time between two adjacent packing wheels.
  • Number 1 in Figure 1 indicates as a whole a packing machine for producing rigid, hinged-lid packets 2 of cigarettes.
  • Each packet 2 of cigarettes comprises a group 3 of cigarettes normally containing twenty cigarettes 4; an inner sheet 5 of foil packing material enclosing group 3 of cigarettes; and a blank 6, which is folded about group 3 of cigarettes, enclosed in inner sheet 5 of packing material, to form a rigid, hinged-lid outer container.
  • a U-folded collar 7 is inserted inside an open top end of the container to engage an inner surface of the lid when the lid is in a closed position.
  • Packing machine 1 comprises a frame 8 (shown schematically in Figure 1), which supports a number of work stations 9 located along a production line 10 and each comprising a respective number of operating devices. More specifically, packing machine 1 comprises eight work stations 9 : a forming station 9a for forming groups 3 of cigarettes 4; a feed station 9b for supplying inner sheets 5 of packing material; a folding station 9c for folding inner sheets 5 of packing material about groups 3 of cigarettes 4; a feed station 9d for supplying collars 7; a folding station 9e for folding collars 7 about groups 3 of cigarettes 4 and over the folded inner sheets 5 of packing material; a feed station 9f for supplying blanks 6; a folding station 9g for folding blanks 6 about groups 3 of cigarettes 4 and over the folded inner sheets 5 of packing material; and a drying station 9h for drying packets 2.
  • a forming station 9a for forming groups 3 of cigarettes 4
  • a feed station 9b for supplying inner sheets 5 of packing material
  • a folding station 9c for folding inner sheets 5 of
  • each work station 9 The main operating devices of each work station 9 will be described as shown in Figures 1 and 2. In actual fact, each work station 9 comprises additional operating devices which the schematic nature of the accompanying drawings does not allow to be shown in detail.
  • Forming station 9a for forming groups 3 of cigarettes 4 comprises a hopper 11 having three outlets for simultaneously feeding three groups 3 of cigarettes 4 to three pockets 12 of a forming conveyor 13.
  • Forming conveyor 13 comprises an octagonal (polygonal) drum 14 which rotates intermittently (or "in steps") about a horizontal axis of rotation 15 perpendicular to the Figure 1 plane.
  • Drum 14 supports four groups of pockets 12, each comprising three pockets 12.

  • Feed device 30 comprises a pickup drum 32 having a number of suction seats 33 (only one shown in Figure 1) for withdrawing blanks 6 from the bottom of hopper 31 and feeding the blanks to an intermediate suction drum 34.
  • Intermediate drum 34 feeds blanks 6 through a gumming station, where gum is deposited on the inner face of each blank 6 by a gumming drum 35, and then releases the gummed blanks 6 onto a feed drum 36.
  • Feed drum 36 feeds blanks 6 through a pre-folding station, where each blank 6 is folded along preformed longitudinal fold lines by a pre-folding member 37, and then feeds the gummed, pre-folded blanks 6 successively (i.e. one at a time) to folding station 9g.
  • Feed drum 36 has a number of suction seats 38, each of which engages a central portion of a blank 6 and is the same shape and size as a group 3 of cigarettes.
  • Pre-folding member 37 is a drum with three lobes, which, as they rotate, fold the lateral portions of each blank 6 against the respective suction seat 38.
  • Folding station 9g comprises a packing conveyor 39 having two arms 40, each rotating intermittently (or "in steps") about an axis of rotation 41 parallel to axis of rotation 15.
  • Arms 40 support four groups of pockets 42, each comprising three pockets 42.
  • a central pocket 42 is fixed with respect to arm 40, while the other two lateral pockets 42 are hinged to arm 40 to rotate, with respect to arm 40 and under the control of a cam actuating system (not shown), about respective axes 43 parallel to axis of rotation 41.

  • Packing machine 1 as described above has numerous advantages. In particular, it provides for high output, by performing the packing operations simultaneously on three pockets, while at the same time allowing a relatively long time interval in which to perform each packing operation. As such, each packing operation can be performed extremely accurately, with no need for complicated, untried technical solutions. Moreover, given the step operation of the packing conveyors, packing machine 1 as described above is cheap and easy to produce and set up. This is achieved by means of the particular method of transferring products between two intermittent conveyors, which provides for troublefree transfer of a number of products at the same time.
