Definitions

  • the present invention relates to an overwrapping machine for continuously packing products in tubular wrappings.
  • the present invention is particularly suitable for overwrapping packets of cigarettes to which the following description refers purely by way of example.
  • Known overwrapping machines for forming tubular wrappings of transparent heat-seal material about packets of cigarettes comprise at least one folding wheel rotating, normally in steps, about its axis, and featuring a number of peripheral, outwardly-open seats. These are fed successively through a loading station where each seat is stopped for receiving a packet together with a sheet of wrapping material, which is fed between the seat and the packet, and is folded in a U about the packet as this is inserted inside the seat. Once folded in a U, the sheet of wrapping material normally presents two opposite end portions projecting outwards of the seat, and which are folded one on top of the other by external folding devices, and then heat-sealed together to form a tubular wrapping. The two end portions are normally sealed by external heat-seal devices mounted in fixed heat-sealing stations.

  • Push elements 86 are fitted to the belt 87 of a loop conveyor 88, and are fed along channel 84 to input 30 of channel 27, so as to feed respective packets 2 parallel to direction 28 and transversely in relation to the longer axis of packets 2, which are arranged with the larger lateral surface contacting plate 85.
  • an output end portion of channel 84 extends through a known roller 84a, which constitutes the output element of feed device 6, is located facing input 30 of channel 27, and rotates in steps about an axis parallel to the axes of pulleys 20 and 24.
  • Transfer unit 9 comprises a known type of crank mechanism 89 defined by a crank 90 and by a connecting rod 91, a free end portion of which constitutes a pusher 92 moving, over a portion of its travel, along said output end portion of channel 84, so as to successively transfer packets 2 into an input portion of channel 27 and in time with the passage, through input 30, of two facing projections 17 and 18 defining the front end of a respective pocket 29.
  • Roller 84a is defined in known manner by two disk-shaped portions connected coaxially and parallel to each other, and between which is defined a passage housing said plates defining channel 84 along which packets 2 are pushed successively, first by pushers 86 and then by pusher 92.

On being cut off strip 94, each sheet 7, retained in known manner by means of suction, is fed by roller 84a into the gap between the output end of channel 84 and the input end of channel 27.
  • input station 8 is located between input 30 of channel 27 and the periphery of roller 84a, and comprises two rollers 96 defining a passage aligned with channels 27 and 84 and the width of which is approximately equal to but no less than the thickness of packets 2.
  • Rollers 96 are located on either side of the axis of channel 27, and are supported on respective meshing gears 97, so as to rotate in opposite directions and at a surface speed substantially equal to the traveling speed of belts 15 and 16.
  • An input portion of channel 27 upstream from pulley 35 in direction 28 is defined laterally by two fixed folding devices 98 (only one of which is shown in Fig.2) separated by a distance approximately equal to but no less than the length of packets 2, and terminating upstream, in direction 28, from said position wherein folding element 83 penetrates inside channel 27.
  • Devices 4, 5 and 6 and unit 9 are obviously so synchronized that, as packet 2 is fed (by known means not shown) to the input of channel 84, and is engaged by a respective push element 86 for transfer to the output end portion of channel 84, strip 94 is fed by device 93 through cutting station 95, so as to feed a sheet 7 on to the periphery of roller 84a.
  • sheet 7 is folded in controlled manner in a U about packet 2.
  • the function of rollers 96 the surface speed of which is, as stated, equal to the traveling speed of belts 15 and 16 and pusher 92, is to prevent axial slide (i.e. in the direction of the axis of sheet 7) between sheet 7 and packet 2.

  • each folding element 57 is maintained substantially perpendicular to belt 33, and is only inclined rearwards (in relation to said perpendicular position and the traveling direction of belt 33) as respective operating unit 38 exits channel 27 about the periphery of pulley 36.
  • Belt 33 is so synchronized in relation to belts 16 that folding element 57 gradually engages the bottom end portion of respective sheet 7 as operating unit 38 travels about the periphery of pulley 35, and folds said bottom end portion on to said rear lateral surface of packet 2 and over said top end portion, which is held by folding element 57 in the downfolded position even after withdrawal of folding element 83 from channel 27.
  • each folding element 57 defines, together with a respective projection 18, a clamping unit 38a for accurately clamping packet 2 inside pocket 29, and accurately controlling the position of packet 2 as it travels along channel 27.
  • the portion of folding element 57 projecting inside channel 27 as operating unit 38 travels along operating side 37 of belt 33 is shorter than the length of said bottom end portion of sheet 7, so that, when folded over said top end portion, the bottom end portion of sheet 7 presents an end portion projecting from the free end of folding element 57, and which is engaged by a respective heat-seal device 69 for laterally sealing tubular wrapping 3 about packet 2.
  • cam 73 is so formed as to rotate heat-seal device 69 rearwards (in relation to the traveling direction of belt 33) as operating unit 38 travels about the periphery of pulley 35, so as to prevent device 69 from interfering with respective folding element 83.
  • Cam 73 is also designed to ensure packet 2 is contacted firmly by folding element 57 before being contacted by heat-seal device 69.
  • the operating time of heat-seal devices 69 i.e. how long device 69 is held contacting packet 2 along channel 27, is adjustable by means of device 76, which, by rotating plate 74 in one direction or the other, provides for anticipating or delaying operation of devices 69 and so increasing or decreasing sealing time, which may thus be optimized even alongside variations in the speed of belts 15, 16 and 33.
  • folding device 10 comprises a bottom plate 99 and a top conveyor 100, which define the output portion of a channel 101 aligned with channels 27 and 84 and parallel to direction 28.

  • Device 10 also comprises two known helical folding elements 108 (only one shown) on either side of channel 101; and a reject device 109 (Fig.2) in turn comprising a plate 110 defining the input portion of plate 99.
  • Plate 110 is integral with a fork 111, which is moved, by an actuating device not shown, about the axis of pulley 25 and between a first position wherein plate 110 is coplanar with plate 99 and closes a reject opening 112, and a second position wherein opening 112 is open.
  • each packet 2 is gradually released by respective folding element 57, is detached from respective projection 18, and slows down until it is engaged by a respective projection 103 by which it is pushed forward along channel 101 and gradually into engagement with folding elements 108, which, in known manner, provide for folding the remaining end portions of tubular wrapping 3 on to the ends of packet 2.
