Definitions

  • the invention relates to a method for wrapping packs, in particular cuboid cigarette packs, in blanks which are placed around the packs in a U-shape when the packs are inserted into pockets of a folding turret and the projecting tabs are then folded, the folding turret being provided with several, in particular two Packs are fed in parallel next to each other and the blanks are separated from a common material web and conveyed into the movement path of the packs in the correct position. Furthermore, the invention relates to a device according to the preamble of claim 6 (such a method and such a device are known from EP-A-0 135 818).
  • Cigarette packs are mostly provided with an outer wrapping made of a thin film.
  • the invention is primarily concerned with the manufacture of the outer wrapper for cigarette packs.
  • Packaging machines for the outer wrapping of cigarette packs must be very efficient, in accordance with the high performance of the upstream packaging machines for the manufacture of the cigarette packs.
  • a packaging machine for producing cigarette packs is known, in which successive cigarette packs are fed in the radial direction to a folding turret. At the same time, two packs are fed side by side in the axial direction.
  • the folding turret provided has particularly large dimensions in the axial direction. Folding elements arranged on the circumference of the folding turret must have a correspondingly wide design.
  • the object of the method and the device according to the invention is to ensure a reliable and simple process of transferring the packs to the folding turret with a "normal" axial length of the folding turret.
  • the method according to the invention is characterized in that the packs - relative to the folding turret - are kept ready next to one another in a common, transverse axial plane and in the circumferential direction and are pushed into the corresponding pockets of the folding turret in this plane.
  • the device according to the invention is characterized in that the pockets for receiving the packs to be supplied next to one another are arranged in the folding turret in a transverse axial plane and parallel to one another in the circumferential direction.
  • the material web is fed to the wrapping station in sections, namely in each case in the dimension of two sections corresponding to web sections.
  • the blanks are in the path of movement of the cigarette packs held ready, directed transversely to them.
  • the conveyor elements for feeding the material web are designed as a conveyor roller, at least one of these conveyor rollers being a knife roller which produces the web section and the blanks by means of a precise separating cut.
  • a conveyor roller is assigned to a cigarette pack or a movement path of the same.
  • These conveyor rollers are provided with a central, slot-shaped passage through which the packs are pushed, taking the blanks held on the jacket of the conveyor rollers.
  • the objects to be packaged - in particular cigarette packs - are inserted from a sealed row of cigarette packs by a lifting movement, taking the blanks with them, into the pockets of the folding turret.
  • Further features of the invention relate to the design of conveying and holding members for the material web and the cuts, to insertion members for the cigarette packs in the folding turret and to the design of the folding turret.
  • the device shown as an exemplary embodiment in the drawings is particularly advantageously suitable for the production or for wrapping cuboid packs 10 in the form of cuboids.
  • it is about the formation of an outer envelope 11 as cellophane, poly film or the like.
  • the outer wrapper 11 consists of a rectangular blank 12 or 13. In a first folding step, this is placed around the cigarette pack 10 in a U-shape, forming a front one in the direction of movement Side wall 14. An overlap of correspondingly dimensioned side wall tabs 16 and 17 is formed in the longitudinal direction thereof on the further side wall 15 opposite this. These are connected to one another in the area of their overlap, in particular by sealing.
  • the first side end flaps 20 and 21 are folded in an extension of the side wall flaps 16, 17 against the bottom wall and end wall of the cigarette pack 10.
  • trapezoidal longitudinal tabs 22, 23 are folded against one another with an overlap to complete bottom wall 18 and end wall 19.
  • the cigarette packs 10 to be wrapped in this way come from a packaging machine (not shown).
  • the cigarette packs 10 are conveyed in a sealing position next to one another on a packing track 24.
  • This consists of a lower wall 25, an upper wall 26 and side guides 27.
  • the cigarette packs 10 are conveyed in cycles by transferring the feed from one cigarette pack 10 to the other.
  • the cigarette packs 10 are transferred to a folding turret 29, which rotates step by step in the vertical plane, by lifting them off the packing track 24 and moving upwards.
  • the folding turret 29 is provided with pockets 30, 31 arranged in pairs.
  • a cigarette packet 10 is inserted from below into the pockets 30, 31, which are open on the radially outer side, with the taking of a correspondingly provided blank 12, 13, which wraps itself around the U-shape Cigarette pack 10 around, starting from the side wall 14 lying forward in the direction of movement.
  • the cigarette packs 10 are conveyed in cycles along a three-quarter circle, by carrying out the folding operations described.
  • the cigarette packs 10 provided with the finished outer wrapper 11 are again pushed out in pairs from the pockets 30, 31 and inserted into a discharge conveyor 33.
  • a double slide 34 is arranged in the region of the insertion station 28, with two plungers 35, 36 arranged at a distance from one another and moving together.
  • a support body 37 common for the tappets 35, 36 is driven up and down in a suitable manner, in the present case via a rocker arm 38 with a link 39.
  • the plungers 35, 36 pass through slot-shaped recesses 40, 41 in the lower wall 25 of the packing web 24.
  • the plungers 35, 36 are arranged at such a distance from one another that a distance corresponding to the dimensions of two cigarette packs 10 is formed between the two cigarette packs 10 lifted out of a sealing row 42 of the cigarette packs 10.
  • a sufficient distance is produced between the cigarette packs 10 to be wrapped in order for the two blanks 12 and 13 to be carried along and for the folding steps to be carried out in the region of the folding turret 29.
  • the cigarette packs 10 are conveyed with the blanks 12, 13 through the plungers 35, 36 to their end position within the pockets 30, 31. After returning to the starting position (flush with bottom wall 25), the sealing row 42 of the cigarette packs 10 conveyed further by a path corresponding to the dimension of two cigarette packs 10, so that a continuous row of seals 42 is created, bearing against an end wall 43 of the pack web 24.
  • the subsequent part of the sealing row 42 is prevented from moving further, namely by clamping forward-lying cigarette packs 10 to the upper wall 26 of the packing web 24.
  • a partial region of the lower wall 25 is designed as a lifting plate 44.
  • the two front cigarette packs 10 are clamped by a slight upward movement and thus the sealing row 42 is fixed.
  • the blanks 12 and 13 are each held in a position exactly above the two upwardly moving cigarette packs 10 in a plane transverse to their path of movement.
  • the cigarette packs 10 exit through an ejection opening 45, 46 of the top wall 26.
  • the blanks 12, 13 are kept ready above this ejection opening 45, 46.
  • the two blanks 12, 13, each associated with a cigarette pack 10, are separated from a common, continuous material web 47 made of packaging material (film).
  • the material web 47 drawn off in sections from a bobbin, not shown, is fed to the insertion station 28 essentially horizontally, at least transversely to the upward movement path of the cigarette packs 10.
  • Two driven and correspondingly controlled pull rollers 48, 49 ensure the precise feed.
  • the material web 47 then runs over a plurality of conveyor rollers which can be driven in rotation. Of these, one adjoining the pulling rollers 48, 49 is designed as a knife roller 50 with a revolving separating knife 51 and a fixed counter knife 52.
  • the knife roller 50 is dimensioned such that in connection with a corresponding relative position a separating cut 53 for separating the two blanks 12 and 13 from one another and then a further separating cut 54 for separating the (second) cut 13 from the material web 47 are made at a suitable point by the separating knife 51 and counter knife 52.
  • the knife drum 50 is provided with suction bores 55 which fix the front, free end of the subsequent material web 47 on the knife drum 50 by means of suction air.
  • the material web 47 is conveyed during each work cycle by a web section corresponding to the dimensions of the two blanks 12 and 13.
  • the cuts 12, 13 and the separation from the material web 47 take place during the transport.
  • the material web 47 or the cuts 12, 13 are transferred directly to the circumference of further roller-shaped conveying members which transfer the material web 47 convey under strong wraps into the folded position (Fig. 4).
  • Roller conveyors 56 and 57 in the area of the insertion station 28 also serve as holding members for the blanks 12, 13 in exact relative position to the upward movement path of the cigarette packs 10.
  • the blanks 12, 13 become from these roller conveyors 56, 57 during the upward movement of the cigarette packs 10 slipping pulled off.
  • the roller conveyors 56, 57 consist of lateral, rotatably drivable suction disks 58, 59. These are each provided on the outside with drivable shaft journals 60.
  • the suction disks 58, 59 are dimensioned in their axial direction and spaced apart such that only edge strips of the material web 47 or the blanks 12, 13 lie on the circumference of the suction disks 58, 59 and are held by suction air. This edge strip corresponds to the width of parts of the blanks 12, 13 projecting beyond the cigarette pack 10 during this phase for the later formation of the bottom wall 18 and end wall 19.
  • Upright support walls 61, 62 and 63, 64 are formed between the lateral suction disks 58, 59. These are assigned in pairs to the suction disks 58, 59 as a fixed, immovable addition to the roller conveyors 56, 57.
  • the support walls 61..64 are designed such that a gap-shaped passage opening 65, 66 is formed in the continuation of the ejection openings 45, 46 for the passage of the cigarette packs 10.
  • the support walls 61..64 are connected to the upper wall 26 of the packing web 24 or form part of the same.
  • the support walls 61..64 are shaped in such a way that the blanks 12, 13 rest in the region of the same on rounded or arched outer surfaces.
  • the support walls 61..64 are adapted to the cylindrical shape as part of the roller conveyors 56, 57.
  • the adjacent support walls 62, 63 flow smoothly into an arcuate guide trough 67 of the correspondingly shaped upper side of the upper wall 26.
  • the material web 47 or the blanks 12, 13 are conveyed through this guide trough 67, bearing against corresponding guide surfaces.
  • the blanks 12, 13 are fixed on the roller conveyors 56, 57 or the suction disks 58, 59 thereof in such a way that there is a slight eccentricity in relation to the associated cigarette packs 10.
  • the cigarette packs 10 are thereby fed into the pockets 30, 31 with unevenly long, downward-facing side wall tabs 16, 17.
  • a further guiding and conveying element is arranged between the roller conveyors 56, 57, namely in the region of the guiding trough 67.
  • this consists of a guide roller 68 which is driven in rotation with the cycle of the other conveying members and which is mounted centrally in the guide trough 67.
  • the guide roller 68 is provided with a plurality of parallel rotations 69 running all around.
  • a plurality of roller sections 70 arranged at a distance from one another in the axial direction are provided for the contact of the material web 47.
  • suction bore 71 opening on the peripheral surface, which fixes the material web 47 or the blanks 12, 13 on the roller sections 70.
  • the suction bores 71 are connected to a central suction line 72 which is connected to a suction line connection 74 in the region of the rotary bearing of the guide roller 68 via a suction ring 73.
  • a fixed counter body 75 is assigned to the guide roller 68. This is arranged centrally between the roller conveyors 56, 57. The lower area is arcuate and adapted to the dimensions of the guide roller 68.
  • the counter body 75 is comb-like here with fingers 76, 77 directed towards both sides. These enter the indentations 69 between the roller sections 70 of the guide roller 68 and cause the material web 47 to be correctly guided during the feed movement, namely from the circumference of the first Transfer roller conveyor 56 to the guide roller 68 and is guided by this to the second roller conveyor 57.
  • the counter body 75 also has a wiper function.
  • the material web (47) or the blanks (12, 13) loop around the roller conveyors (56, 57) and the guide roller (68) by more than half.
  • the separating cut (53) for dividing the two blanks (12, 13) lies from one another in the area of the guide roller (68), somewhat off-center, so that when the blanks (12, 13) are taken over by the associated cigarette packs (10), the blanks (12, 13) slip on the one hand from the roller conveyors (56, 57) and on the other hand, be pulled in opposite directions from the guide roller (68).
  • the strongly curved course of the material web 47 or the blanks 12, 13 is particularly evident from FIG. 6.
  • This shape of the material web 47 makes it possible to arrange the cigarette packs 10 to be pushed out together at a short distance from one another, despite the considerable dimensions of the blanks 12, 13 in the conveying direction.
  • the arrangement of the conveyor rollers 50, 56, 57 and 68 relative to one another is such that the material web 47 is transferred directly from the circumference of one conveyor roller to the other.
  • Each of these conveyor rollers is provided with radially directed suction bores 55 and 71 or 78 and 79, each of which grips an edge region of the material web 47 or of the blanks 12, 13 lying forward in the conveying direction and thus secures the transport.
  • the suction bores When a blank 12, 13 is transferred from one of these conveyor rollers to the next, the suction bores momentarily come into an adjacent relative position (in FIG. 6 with the roller conveyor 56 and the guide roller 68). During the phase of the transition, the suction bore 78 holding the blank 13 up to that point is briefly vented, so that the blank is reliably transferred to the next conveyor roller.
  • the roller conveyors 56, 57 are each provided with individual suction bores 78, 79 in the area of the suction disks 58, 59.
  • the knife roller 50 is equipped with a row of suction bores 55 running through in the axial direction (FIG. 5).
  • the system of suction bores is essentially designed in a conventional manner.
  • the suction bores are axially parallel within the conveyor rollers Suction lines 80 connected. These open at the front ends of the conveyor rollers on non-rotatably mounted suction disks 81, shown in section in FIG. 5 by means of the roller conveyor 56.
  • the suction disks 81 are each pressed by pressure springs 82 in a sliding and sealing manner against the facing end faces of the conveyor rollers.
  • the suction disks 81 are also provided with circular suction grooves 83 which are open to the end faces of the conveyor rollers and with which the ends of the suction lines 80 temporarily overlap during the rotational movement of the conveyor rollers. Suction air is transmitted during this overlap phase.
  • the length of the suction grooves 83 therefore corresponds to the duration of the suction phase.
  • a vent hole 84 Adjacent to, but outside of, the suction grooves 83, a vent hole 84 is provided, where necessary, on the same circular arc as the suction grooves 83, so that the suction line 80 overlaps with the vent hole 84 during a brief phase of the rotational movement and thereby the already described ventilation of the suction bores causes.
  • Fig. 7 shows the relative position of the suction grooves 83 and vent holes 84 for the conveyor rollers 50, 56, 57 and 68.
  • the cigarette packs 10 with the blanks 12, 13 pass through a mouthpiece which passes through fixed outer walls 85, 86 on the one hand and through the correspondingly shaped counter body 75 on the other hand is formed.
  • the cigarette packs 10 are held in the pockets 30, 31 formed by two pocket walls 87, 88 in such a way that the side wall tabs 16, 17 protrude from the pockets 30, 31.
  • first folding members come into action, namely, side folders 89 and 90 which are arranged concentrically to the folding turret 29 and can be pivoted back and forth 89, the shorter, inner side wall tab 17 of the pockets 30 rearward in the direction of rotation of the folding turret 29 is first folded over.
  • the inner side wall tab 17 of the adjacent pocket 31 is simultaneously folded over by a corresponding oscillating movement of the side folder 90.
  • the folding turret 29 begins to rotate, the longer, outer side wall tab 16 of the pocket 31 is folded over by the edge of a stationary outer guide wall 91 of the folding turret 29.

  • the first folding process takes place, namely the folding in of the side end flaps 20 lying in the direction of insertion by folding fingers 94 as a lateral limitation of the pockets 30, 31.
  • the folding takes place thereby by relative movement of the cigarette packs 10 to these folding fingers 94.
  • the folding fingers 94 are provided with suction bores 95 on the side surfaces pointing in the direction of rotation of the folding turret 29.
  • the folding fingers 94 also form the lateral boundaries of the pockets 30, 31. Further suction bores 96 open out in the region of end faces 97 of the folding fingers 94.
