Definitions

  • the present invention relates to a method of wrapping articles.
  • the present invention relates to a method of wrapping packets of cigarettes in sheets of overwrapping material, to which the following description refers purely by way of example.
  • Packets of cigarettes are normally wrapped in overwrapping material, in particular, respective sheets of polypropylene, to preserve the aroma and correct humidity of the tobacco.
  • overwrapping material in particular, respective sheets of polypropylene
  • cellophaning machines which comprise a first wrapping wheel along which a sheet of polypropylene is folded into a tube about a respective packet to form a tubular wrapping having projecting portions at the ends of the packet; and a second wheel along which the projecting portions of the tubular wrapping are folded onto the opposite ends of the packet of cigarettes.
  • the method employed by known cellophaning machines provides for positioning a sheet of wrapping material in a fixed position along the path of a respective packet; feeding the packet against the sheet so that the sheet of wrapping material is drawn by the packet towards fixed folding surfaces located along the path of the packet and which form a first U-shaped fold about the packet; and completing the tubular wrapping by means of movable folding devices located along the path of the packet.
  • a first embodiment provides for feeding the packet along a given path on a wheel, positioning a sheet of wrapping material crosswise to the path of the packet, feeding the packet against the sheet of wrapping material, and drawing the sheet of wrapping material towards a fixed spindle to form the U-shaped fold about the packet;
  • a second embodiment provides for rotating a wrapping wheel having pockets each comprising a bottom wall and two lateral walls, positioning a sheet of wrapping material opposite each pocket, keeping each sheet at a given distance from the bottom wall of the pocket by means of gripping members located at the lateral walls of the pocket, inserting a respective packet into the pocket so as to collide with the respective sheet of wrapping material, and drawing the sheet into and towards the bottom wall of the pocket so as to fold the sheet of wrapping material against the lateral walls and form the U-shaped fold about the packet.
  • German Patent Application No. 1,511,585 in which the cellophaning machine is designed to operate continuously.
  • the demand for increasingly high-output cellophaning machines calls for rotating the wrapping wheels continuously at relatively high speed.
  • the cellophaning machine described in German Patent Application No. 1,511,585 and implementing the second embodiment of the wrapping method described above fails to provide for high production speeds on account of a number of drawbacks.
  • One of the main drawbacks lies in the relatively high speed at which the packet on continuous machines collides with the sheet of wrapping material, thus resulting in stretching and, in some cases, in tearing of the sheet, on account of the continual reduction in the thickness of the polypropylene sheets for environment reasons and to reduce consumption of raw materials.
  • a further drawback lies in the sheet slipping with respect to the packet as the sheet is drawn by the packet into the respective pocket. That is, though the distal ends of the lateral walls release the sheet as it is drawn inside the pocket, residual adherence of the sheet to the distal ends of the walls causes the sheet to slide with respect to packet. Adherence of the sheet to the ends of the walls is a frequent occurrence, and is caused by electrostatic charges or by residual suction exerted by suction retaining members.
  • EP-503215-A1 discloses a continuos wrapping machine, which partially overcomes the above drawbacks.
  • the wrappings produced by the wrapping machine disclosed in EP-503215-A1 have a relatively poor quality, owing to the fact that each wrapping sheet is U-folded around a respective product by pliers means, which are not able to sufficiently stretch the wrapping sheet around the product.
  • an insufficient stretching of the wrapping sheet around the respective product results in a poor-quality wrapping when the wrapping sheet is made by transparent plastic foil like polypropylene.
  • the invention provides for preventing deformation of the sheet of wrapping material as the article is brought into contact with the sheet, by the sheet being laid flat and supported rigidly on a plate so that the high speed of the packet does not damage the sheet or result in incorrect positioning of the sheet with respect to the article.
  • the present invention also relates to a machine for wrapping articles.
  • Number 1 in Figure 1 indicates as a whole a cellophaning machine for overwrapping packets 2 of cigarettes in sheets 3 of polypropylene.
  • Machine 1 comprises a wrapping wheel 4; a wrapping wheel 5 indicated by the dash line in Figure 1; a supply device 6 for supplying packets 2; and a supply device 7 for supplying sheets 3.
  • Wheel 4 comprises a disk 8 rotating, anticlockwise in Figure 1 and in a direction D1, about a respective axis 9 perpendicular to the Figure 1 plane; and a number of conveying units 10 for conveying packets 2 and respective sheets 3 along a path P1. Units 10 are equally spaced about axis 9 with a spacing S, and are supported by disk 8.
  • a supply station 11 where sheets 3 are supplied to respective units 10
  • a supply station 12 where packets 2 are supplied to respective units 10
  • a wrap-around station 13 where sheets 3 are wrapped about respective packets 2
  • two folding stations 14 and 15 where sheets 3 are folded about respective packets 2
  • a transfer station 16 where packets 2 together with respective sheets 3 folded into a tube about packets 2 are transferred to wheel 5.
  • each unit 10 comprises a plate 17; a gripping device 18 for gripping packets 2; and a folding tool 19.
  • Each plate 17 is located at the periphery of disk 8, extends perpendicularly with respect to disk 8, and comprises a flat portion 20, and a curved portion 21 which, in practice, is defined by a cylindrical plate curving about axis 9. Portions 20 and 21 are connected to each other and so arranged that curved portion 21 is located in front of flat portion 20 in traveling direction D1.
  • Each plate 17 is defined by a face 22 facing axis 9, and by a supporting face 23 opposite face 22 and having a number of holes 24 equally spaced on face 23 and connected to known suction channels not shown.
  • Each folding tool 19 comprises a rod 25 extending perpendicularly to portion 20 of plate 17 and engaged in a guide 26 integral with disk 8.
  • the end of rod 25 facing plate 17 comprises a folding blade 27 tapering towards the end and housing a heating body 28 for sealing polypropylene sheet 3 along packet 2, i.e. for making the longitudinal lateral seal.
  • the end of rod 25 facing axis 9 comprises a tappet roller 29 which cooperates with a fixed cam profile 30 shown by the dash line in Figures 1 and 2; and guide 26 houses a known spring (not shown) for pushing rod 25 towards profile 30 to keep roller 29 in contact with profile 30.
  • each device 18 for gripping packets 2 comprises a shaft 31, which is located between respective plate 17 and axis 9, extends perpendicularly through and on opposite sides of disk 8, and is supported by a bush 32 fitted to disk 8.
  • Shaft 31 rotates about a respective axis 33 parallel to axis 9, and has one end integral with a rocker-arm lever 34 having two tappet rollers 35 and 36 guided by respective fixed cams 37 and 38 to orient shaft 31 about axis 33.
  • a second end of shaft 31 is integral with a lever 39 supporting a rod 40, the ends of which in turn support for rotation two rocker arms 41 rotating about respective axes 42 parallel to each other and to the Figure 1 and 2 plane.
  • each rocker arm 41 comprises a hub 43 which supports an arm 44 extending perpendicularly to axis 42 and supporting a gripping member 45 at the distal end, and an arm 46 extending perpendicularly to axis 42 and arm 44, and which supports at the distal end a tappet roller 47 cooperating with a respective cam 48 for controlling rotation of rocker arm 41 about axis 42.
  • a spring 49 is provided between each hub 43 and rod 40 to transmit torque about axis 42 to the respective rocker arm 41, so that the two gripping members 45 are pushed towards each other.
  • each gripping member 45 comprises a substantially parallelepiped plate 50 extending crosswise with respect to respective arm 44; and three blades 51, 52, 53 - which may be fewer or dispensed with entirely - extending parallel to axis 9 from three adjacent faces of plate 50 to grip a packet 2 of cigarettes.
  • Each packet 2 of cigarettes comprises two parallel, opposite main faces 54, two lateral faces 55 and two end faces 56, and has a longitudinal axis 57 parallel to faces 54 and 55.
  • Gripping members 45 grip packets 2 by opposite end faces 56. That is, plates 50 are positioned contacting respective end faces 56, blades 51 and 52 are positioned contacting small end portions of opposite faces 54, and blades 53 are positioned contacting small end portions of front face 55 in traveling direction D1.
  • device 7 comprises two pairs of rollers 58 for feeding a polypropylene strip 59, and a roller 60 cooperating with a counter-roller 61 to cut successive sheets 3 off strip 59.
  • Roller 60 has known suction holes (not shown) for retaining sheet 3 about roller 60 and gradually releasing sheet 3 onto a respective plate 17.
  • Roller 60 in fact, is substantially tangent to plates 17 so that each sheet 3 is fed tangentially onto a respective plate 17.
  • device 6 feeds packets 2, equally spaced with a spacing S1 and at a steady speed, along a path P2 substantially tangent to path P1 and extending in a direction D2.
  • Device 6 comprises two belt conveyors 62 and 63 and a plate 64; conveyors 62 and 63 comprise respective belts 65 and 66 along which respective draw teeth 67 are equally spaced with spacing S1; conveyor 62 comprises a top conveying branch 68 parallel to and partially facing a bottom conveying branch 69 of conveyor 63; and plate 64 forms an extension of branch 68 and is parallel to and faces branch 69.
  • Packets 2 are fed along path P2 with respective longitudinal axes 57 perpendicular to the Figure 1 and 2 plane, and are fed substantially tangentially onto respective plates 17.
  • the end portion of plate 64 is located at wheel 4, directly over path P1, and, as a packet 2 reaches said end portion of plate 64, gripping members 45 of a unit 10 grip packet 2 as described previously, and transfer packet 2 onto a respective sheet 3 on plate 17 without altering the configuration of sheet 3.
  • Wrap-around station 13 comprises a lobed drum 70 rotating about a respective axis 71 parallel to axis 9 and comprising two diametrically-opposite lobes 72, which have respective faces 73 in the form of a cylindrical sector curving about axis 71, and a number of suction holes 74 connected to known suction channels not shown.
  • Each face 73 is tangent to face 23 of each plate 17 at curved portion 21 of plate 17.
  • Folding station 14 comprises a curved plate 75 with a curvature centered with respect to axis 9, and having bristles 76 facing axis 9.
  • Plate 75 is preceded, in traveling direction D1 in Figures 1 and 2, by a roller 77 rotating about a respective axis 78 parallel to axis 9.
  • a movable folding tool 79 comprises a fixed support 80 supporting a plate 81 rotating with respect to support 80 about an axis 82 parallel to axis 9.
  • wheel 4 is rotated at a constant speed V1 about axis 9 in direction D1.
  • device 7 feeds sheets 3 successively onto respective plates 17 of units 10 as described previously.
  • Each sheet 3 is fed tangentially onto respective plate 17, and has a portion 83 contacting flat portion 20, a portion 84 contacting curved portion 21, and an end portion 85 projecting from flat portion 20 at the rear of plate 17 in traveling direction D1.
  • Each sheet 3 is arranged on respective plate 17 in a preferably flat configuration; portions 83 and 84 in fact adhere to face 23 of plate 17, and portion 85 is maintained coplanar with portion 83 by the air resistance as wheel 4 rotates.
  • Each unit 10 with respective sheet 3 travels through station 12 where device 18 removes packet 2 off plate 64 and deposits it onto flat portion 20 with sheet 3 interposed between packet 2 and portion 20 of plate 17. More specifically, as unit 10 nears station 12, shaft 31 is rotated anticlockwise in Figures 1 and 2 to move gripping members 45 away from plate 17 and into a position facing end faces 56 of a packet 2 on the end portion of plate 64. At the same time, cam 48 acts on rocker arms 41 so as to part gripping members 45 of unit 10. When members 45 are positioned facing faces 56, cam 48 is interrupted and rocker arms 41 are rotated by respective springs 49 to move plates 50 up to respective end faces 56 of packet 2.
  • unit 10 travels past lobed drum 70, which rotates clockwise in Figures 1 and 2 to bring faces 73 of lobes 72 into tangential contact with respective faces 23 of curved portions 21.
  • the suction through holes 74 in face 73 is activated, and the suction through holes 24 in face 23 at curved portion 21 is deactivated, so that portion 84 of sheet 3 is wrapped about axis 71 of drum 70 and therefore lifted off plate 17 and decelerated with respect to portion 83 and packet 2 traveling in direction D1
  • portion 84 occupies a position of interference with path P1, i.e.
  • portion 84 is positioned crosswise with respect to path P1 of respective packet 2; the deceleration of portion 84 causes packet 2 and gripping members 45 holding packet 2 in position to gradually collide with portion 84; and, as wheel 4 and drum 70 rotate further, portion 84 is gradually released by face 73, is wrapped gradually about front face 55, and, when finally released by face 73, is simply blown by air resistance onto face 54 of the packet.
  • sheet 3 is substantially folded into a U about packet 2.
  • portion 83 is located between one face 54 and portion 20, and portion 84 is positioned contacting front face 55 and a main face 54, and has a portion 86 projecting from face 54 and facing portion 85.
  • packet 2 and respective U-folded sheet 3 are fed past roller 77 - which rolls along portion 84 contacting face 54 to ensure portion 84 adheres firmly to face 54 - and in rapid succession past plate 75, the bristles 76 of which iron portion 84 to iron sheet 3 on packet 2 and so smooth out any wrinkles in sheet 3.
  • tool 79 brings plate 81 into contact with rear face 55 so as to fold portion 86 onto rear face 55.
  • rod 25 is pushed by profile 30 outwards of wheel 4 to bring blade 27 into contact with rear face 55 and fold portion 85 onto portion 86 on rear face 55. Blade 27 is maintained contacting the folded portion 85 to enable body 28 to seal portion 85 to portion 86, i.e. to effect the longitudinal lateral seal.
  • packet 2 and respective tubular-folded sheet 3 are transferred at station 16 to wheel 5 on which further known folding operations (not shown) are performed.
