Definitions

  • the invention relates to a device for wrapping objects, in particular groups of cigarettes, into a blank made of packaging material, which is held at least on two lateral edge regions by endless conveyors in a plane transverse to the direction of transport of the object and by pulling off the endless conveyor in a U-shape around the object is foldable.
  • the subject of the present invention is the packaging of objects, in particular groups sensitive to mechanical stresses, for example groups of cigarettes, which are intended for a cigarette pack.
  • the cigarette groups usually supplied in the longitudinal direction of the cigarettes during packaging are often or predominantly encased in such a way that an in a blank held transversely to the transport path of the cigarettes is placed in a U-shaped manner by the relative movement of the group around an end face of the group lying forward in the transport direction.
  • the invention further relates to keeping the relevant blank in an exact relative position and, despite the high output of the machine, that is to say despite the high conveying speed of the cigarette group, to place it precisely and wrinkle-free. This should also apply to critical packaging material which, due to its low rigidity, cannot be processed properly without constant positive guidance.
  • a device for the packaging of relatively dimensionally stable and mechanically more resilient objects, namely finished cigarette packs, in a cellophane or plastic film, a device is known from DE-PS 11 69 361 in which the cut by two laterally engaging and one on both sides Packing track for the object arranged suction discs is fixed and kept ready.
  • the circumferential suction disks are provided with suction bores on the circumference, each of which grips an edge area of the blank.
  • the cigarette pack is conveyed between the suction disks and pulls the blank from the suction disks with the U-shaped wrapping of the pack.
  • This known device which is also used for processing, for example, thin and therefore critical packaging material; is suitable, causes a relatively high mechanical load on the object to be wrapped, especially during the phase of the takeover of the blank by the front face of the object and during the subsequent removal of the suction discs. During this initial phase, the holding force exerted on the blank by the suction disks is greatest.
  • the finished cigarette packs to be processed in the known device can absorb the loads that occur.
  • the invention has for its object to further develop and improve a device of the type mentioned in such a way that sensitive objects, in particular unpacked groups of cigarettes, can also be encased in relation to mechanical loads without thereby having to accept any impairment of the objects is.
  • the device according to the invention is characterized in that the object - in particular the cigarette group - is accommodated in a mouthpiece which is flush with the object on the front side in the transport direction or slightly protrudes therefrom and by which the Cutting is removable or detachable from the endless conveyor at least during an initial phase of the wrapping process.
  • the cigarette group is therefore temporarily accommodated in a support device (mouthpiece) which protects the cigarette group against the mechanical stresses caused by the cut taken over by the suction disks.
  • the mouthpiece which practically completely encloses the cigarette group, is formed on the front side with a sharpened edge, which detects the cut due to a corresponding relative position to the cigarettes and at the same time the initiation of an exact U-fold causes.
  • the sensitive front edges of the cigarettes in the outer area are protected against the mechanical stress of the slightly exciting blank.
  • the U-fold becomes cleaner when folded around a firm edge.
  • the suction disks are provided with several groups of suction bores distributed along the circumference. These only capture the cut in certain critical areas. After the cut has been taken over by the mouthpiece and subsequently by the cigarette group, the suction bores are switched off and vented from the negative pressure sources, so that the cut can subsequently be put around the cigarette group without any restraining force by the suction disks while the latter is in a subsequent mouthpiece-like receptacle, namely entering a packing web.
  • the suction discs enable the blanks to be fed very precisely at high working speeds. Nevertheless, the cut is handed over to the cigarette groups gently, without undue stress on them.
  • the present exemplary embodiment relates to the wrapping of cigarette groups 10. These are fed continuously at intervals from one another and in the longitudinal direction of the cigarettes on a packaging web 11. This is designed so that the as yet unpacked cigarette groups 10 are kept in the group formation.
  • the packaging track is designed with an upper wall, lower wall and side boundaries.
  • the cigarette groups 10 are transported here by an endless conveyor in the form of a chain conveyor 12.
  • the catches 13 enter the packing track 11.
  • the lower wall is formed with a longitudinal slot for the passage of a web of the drivers 13.
  • the cigarette group 10 is to be encased in a blank 14, in such a way that it is U-shaped around the in Transport direction front end 15 is placed around.
  • side tabs of the blank 14 protruding laterally protruding here are pre-folded in the region of the end face 15.
  • the blanks 14 are separated from a continuous web 16 of packaging material by a separating device 17.
  • a knife roller 18 equipped with suction bores and subjected to negative pressure transfers the cut blanks 14 to an endless conveyor in the form of two coaxially spaced suction disks 19 and 20. These are along their peripheral surface 21 receiving the blank 14 with suction openings, namely groups of suction bores 22 and 23a, 23b or suction slits. Negative pressure is applied to these with special control, such that the blank 14 is held by the suction disks 19, 20 during its conveyance, but is then released, namely when it is taken over by the cigarette group 10.
  • the suction disks 19, 20 are arranged at such a distance from one another that the cigarette group 10 can be passed between the suction disks 19 and 20.
  • the blank 14 is kept ready in such a way that in the present case a central area of the same system on the end face 15 of the cigarette group 10 is obtained.
  • the chain conveyor 12 By further transporting them - carried out by the chain conveyor 12 - the cigarette group 10 with the blank 14 is inserted into a further packaging web 24.
  • the pack track 24 equipped with lateral guide means, namely folding thumbs 27 and 28. These come to rest on the side surfaces of the cigarette group 10 and also have the function of folding the protruding side tabs against the cigarette group 10.
  • the cigarette group 10 is received in a mouthpiece 29.
  • this is designed as a housing which is open at both ends, that is to say with a top wall 30, bottom wall 31 and side walls 32, 33.
  • the cross section of the mouthpiece 29 is chosen such that the unpacked cigarette group 10 is fixed in compliance with the formation of the cigarettes.
  • the mouthpiece 29 is slidably mounted with an exact fit between the suction disks 19 and 20, in the present case exactly in the middle position with respect to the suction disks 19, 20.
  • the passage of the mouthpiece 29 runs horizontally, namely in the height or in the extension of the packing web 11
  • the side walls 32, 33 of the mouthpiece 29 are thin-walled in order to keep the distance between the cigarette group 10 and the suction disks 19, 20 small.
  • the cigarette group 10 is introduced via a rear inlet opening 34 with a funnel-shaped design into the mouthpiece 29, namely through the driver 13 of the chain conveyor 12.
  • the bottom wall 31 of the mouthpiece 29 is for this purpose with a slot 35 in the longitudinal direction for the passage the driver 13 or the webs of the same.
  • the mouthpiece 29 can be moved back and forth in the conveying direction of the cigarette group 10.
  • the mouthpiece 29 with support members 36 is slidably mounted on guide rods 38, which in the present case are arranged laterally outside the packaging path 11.
  • the mouthpiece 29 can be driven by a crank mechanism.
  • the cigarette group 10 can also be moved relative to the mouthpiece 29 in the conveying direction thereof during the movement stroke.
  • the movements are coordinated so that the mouthpiece 29 moved between the suction disks 19, 20 with a sharpened front edge 40 with the cigarette group 10 still set back detects the blank 14 fixed by the suction disks 19, 20 and subtracts them from them as the movement continues. 1 shows the moment when the blank 14 is taken over by the front edge 40 of the mouthpiece 29.
  • FIGS. 3, 1 and 4 show the starting position, in which the blank 14 is still in the phase of transport to the end position.
  • the mouthpiece 29 is shown in the retracted position. Only when the blank 14 has reached a relative position in relation to the mouthpiece 29 or packing web 11, which corresponds approximately to that according to FIG. 1, is the takeover carried out by the mouthpiece 29 emerging from the area of the suction disks 19, 20 with the front edge 40 the cigarette group 10 has been moved relative to the mouthpiece 29 in such a way that the shortly thereafter the already U-shaped pre-shaped blank 14 is taken over by the cigarette group 10 emerging from the mouthpiece 29.
  • the top wall 25 and bottom wall 26 are provided with a sharpened, funnel-shaped inlet edge 41.
  • the aforementioned inlet edges 41 are arranged in the immediate vicinity of the circumference of the suction disks 19, 20, so that the mouthpiece 29 carries out a relatively narrow stroke.
  • the folded thumbs 27 and 28 rounded at the free end are set back in relation to the leading edges 41 in the present case.
  • folding thumbs 27, 28 are movable, such that they run toward the cigarette group 10 with the blank 14, with a greater distance between the circumference of the suction disks 19, 20 on the one hand and the packing web 24 on the other hand.
  • the suction disks 19, 20 are provided with the first group of suction bores 22 - for example a row of suction bores lying side by side in the axial direction. This is arranged in such a way that an area of the blank 14 lying forward in the transport direction is taken over and fixed.
  • the aforementioned suction bores 22 are acted upon via a ring line 42, which extends over a wide circumferential range of the Extend suction disks 19, 20.
  • the blank 14 is fixed by the suction holes 22. It is possible to release the area in front of the blank 14 before the end position is reached and it is taken over by the mouthpiece 29, so that the relevant part of the blank 14 sags downward in the sense of FIG. 1.
  • the two other groups of suction bores 23a and 23b are arranged at a distance from one another and at a distance from the suction holes 22 such that when the blank 14 is reached in the position for transfer to the mouthpiece 29 lie on both sides thereof (position according to FIG. 1).
  • the blank 14 is accordingly fixed during the takeover phase by the mouthpiece 29 and the cigarette group 10 directly on both sides of the mouthpiece 29, and only for a moment of the uninterrupted movement.
  • the suction bores 23a lying in front in the circumferential direction are then in the region of a further ventilation bore 44, as a result of which the negative pressure in both groups of suction bores 23a, 23b drops, as a result of a connecting channel 45 between the suction bores 23a, 23b.
  • the blank 14 is therefore completely free of restraining forces on the circumference of the suction disks 19, 20 at this moment.
  • the ring line 42 and the ventilation bores 43 and 44 are formed by stationary, that is to say non-rotatable, air control rings 46 which are pressed against the outer surfaces of the suction disks 19, 20 by springs 47.
  • the suction air is supplied via a central suction line 48 in a drive shaft 49 of the suction disks 19, 20 and across or radially directed connecting lines 50, 51 are supplied with negative pressure.
  • the air control rings 46 are fixed by a rotation lock 52 to outer, fixed bearing cheeks 53.
  • the air channels 54 and 55 for the suction bore 23a, 23b on the one hand and the ventilation channel 56 for the suction bore 22 on the other are on different (imaginary) arcs.
  • the shape of the ring line 42 is adapted accordingly and in the area of the takeover of the blank 14 - in FIGS. 1, 3 and 4 above - with a larger cross section in the radial direction. In this area, the suction bores 22 and the suction bores 23a, 23b are supplied by the common ring line 42. Outside the area of the widened cross section of the ring line 42, the suction bores 23a, 23b are separated from the vacuum source.
  • the separating device 17 is also designed in a special way.
  • the continuously rotating knife roller 18 is equipped with two separating knives 57 and 58.
  • the separating knife 57 which projects beyond the circumference of the knife roller 18, interacts with a stationary counter knife 59.
  • the separating cut for separating the blank 14 from the subsequent web 16 is carried out in this area.
  • the separating knife 58 is somewhat reset. It works together with a correspondingly protruding counterpart, namely in the present case with a counter roller 60 which rotates through a carrier roller 61.
  • the movements of the knife roller 18 and the carrier roller 61 are on top of each other Voted.
  • the counter-rotating roller 60 which is rotatable by itself, projects beyond the circumference of the carrier roller 61, which in turn is at a distance from the circumference of the knife roller 18, in such a way that the projecting separating knife 57 can run past the circumference of the carrier roller 61 with a sufficient distance.
  • the separating knife 58 and counter roller 60 perform a perforation cut in the blank 14, specifically to delimit a flap. The relative position is such that first the separating cut in the area of the separating knife 57 and counter knife 59 and then the perforation cut in the area of the separating knife 58 and the counter roller 60 are carried out.
  • the knife roller 18 rotates at a somewhat higher speed than the feed speed of the web 16.
  • the suction rollers 19, 20 rotating at the same speed have a somewhat lower speed than the cigarette group 10.
  • the knife roller 18 is provided with suction bores .62 and 63, the air channels 64 and 65 of which likewise lie on different orbits and are therefore acted upon differently by a common ring line 66 with a non-uniform cross section. Due to the larger number of suction bores 62 distributed along the circumference, the blanks 14 or the web 16 are only fixed along a relatively small circumferential section - predetermined by a radially inward widening of the cross section of the ring line 66 - while a single group of bores 63 each a front area of the web 16 or the blank 14 from the takeover until delivery to the suction disks 19, 20 fixed. The end of this holding force is determined by a vent hole 67 formed in the lower region.
  • the construction and design and supply of the suction bores 62 and 63 are carried out in an analogous manner to the suction disks 19, 20.
