Definitions

  • the invention relates to soft packs consisting of plastic film, namely paper handkerchief packs which can be packaged into a container (large pack) from several of these small packs by means of an outer wrapping likewise made of plastic film.
  • the container can consist of six, eight, ten, twelve, eighteen or more small packs (paper handkerchief packs).
  • the protruding longitudinal tabs are folded against the back of a group of small packs, the upper and the lower longitudinal tabs overlapping in an end region thereof.
  • the sealing takes place in such a way that pressure and heat are exerted from the outside towards the package.
  • a method for wrapping chocolate bars is known from CH-A-426 609.
  • the preamble of claim 1 corresponds to this prior art.
  • a wrapping film is placed around a U-shaped sheet when it moves.
  • There are folding members which seal longitudinal tabs projecting against the conveying direction with one another to form an edge strip.
  • the edge strip is formed at the top of the object.
  • the folding elements must be readjusted for folding thicker objects.
  • the edge strip is not sealed to the back.
  • the object of the present invention is to further increase the reliability of the folding process and still enable a simple format change.
  • the advantages achieved by the invention are, in particular, that no heat and no pressure is exerted on the inner pack when the outer casing is sealed. Instead, the sealing is carried out by heat and pressure on the back next to the group of small packs in an extension of one long side of the same.
  • the edge strip that emerges from the sealing of the upper and lower side tabs and is formed by them is then folded around against the envelope and sealed with it.
  • the same material can be used for both the outer wrapper and the inner wrapper.
  • the lower butterfly is designed as a sealing organ and is located on the back of the group next to it. It can be moved up and down and can therefore be used to seal different pack sizes. In addition, the underfold folds the edge strip up to the contact with the outer wrapper by moving it upwards. This double function of an organ means that only a relatively small number of packaging elements need to be replaced when the format is changed.
  • the exemplary embodiments shown in the drawings deal with the production of large packs, so-called containers 20, from a plurality of small packs 21, in the present case paper handkerchief packs.
  • the containers 20 are set up for this purpose Packaging machine, a pack packer 22, manufactured. This is part of a manufacturing and packaging system for paper handkerchiefs, a "line”. It consists of a folding machine 23, a handkerchief packaging machine 24, one of these downstream tape units 25 for attaching a sealing strip to the small package 21, a stacking head 26, the subsequent packer 22 and a carton packer 27 connected to it.
  • the small packs 21 are produced in two lines in the present exemplary embodiment.
  • a common row of packs 28 is formed from possibly several small packs 21 arranged one above the other. This is fed to the packer 22 by a feed conveyor 29.
  • the large packs can have different dimensions, depending on the number of small packs 21 per pack 20.
  • Small packs 20 consist of six small packs 21, large packs 20 contain z.
  • the container 20 is formed by a covering 31 made of plastic film.
  • the pack packer 22 is designed in such a way that packs 20 of different sizes can be moved by replacing packaging elements.
  • Packaging organs are folding organs for the wrapping 31, sliders for the transport of the groups 30, conveying organs for film webs and sealing organs.
  • the number and type of packaging elements result from the design of the container 20 or the steps for the production of the wrapper 31.
  • the wrapping 31 is folded in a special way and leads to a container 20 that is special with respect to the wrapping 31.
  • the folding sequence is shown in FIGS. 2 to 6.
  • a blank for the wrapper 31 is held ready in the vertical plane and folded in a U shape around the contents (group 30) by conveying the group 30 through the plane of the blank.
  • horizontally directed longitudinal tabs 32, 33 which initially protrude at the rear of group 30 have different lengths.
  • the upper longitudinal tab 32 is dimensioned such that the rearward-facing long side of the container 20 or the group 30 is covered at full height.
  • This longitudinal tab 32 is folded against the back of the group 30 in the upright position (Fig. 3).
  • a lower edge tab 34 of the longitudinal tab 32 is placed on the upper side of the correspondingly dimensioned lower longitudinal tab 33 and sealed with it by heat and pressure (FIG. 3 and detail in FIG. 7).
  • a double-layered edge strip 35 formed in this way is then folded into an upright position until it rests on the side face or on the upper longitudinal tab 32 (folded position according to FIG. 4).
  • Front side flaps 36 and rear side flaps 37 are successively folded against the side surface of group 30.
  • the front side tab 36 is folded (FIG. 2).
  • the rear side tab 37 Only later, namely after completion of the rear wall of the envelope 31, is the rear side tab 37 folded by corresponding movement of a folding member (FIG. 5).
  • upper lobes 38 and lower lobes 39 are folded over to rest against the side surfaces or on the side lobes 36, 37 (FIG. 6).
  • Upper lobe 38 and lower lobe 39 on the one hand and Side tabs 36 and 37, on the other hand, are sealed together by heat and pressure.
  • the means required for this folding and sealing process together form a complete set of packaging elements.
  • the bundle packer 22 is assigned a plurality of sets of packaging members, these being expediently completely interchangeable to adapt to different formats of the bundles 20.
  • the pack packer 22 shown and described here is set up to accommodate two sets 40, 41 of the packaging members. These sets 40 and 41 are located in a packaging station 42. Each of the sets, in the example shown in FIG. 1, the set 40 is located in the packaging position 43. The small packages 21 or the groups 30 are fed to this.
  • the sets 40 and 41 are detachably connected to an adjustable carrying device, namely a rotating mechanism, which alternatively moves the sets 40, 41 into the packaging position 43 or into an exchange position 44 by rotating movement.
  • an adjustable carrying device namely a rotating mechanism
  • the packaging members of the set 41 are preferably completely replaced as a unit.
  • the slewing gear here consists of an upright support column 45 which is firmly connected to a machine frame or a drive housing 46.
  • a cross member 47 is rotatably mounted on the support column 45.
  • holders for the sets 40, 41 are attached, namely transverse support rods 48.
  • the packaging members of the sets 40, 41 are removable, namely removable, attached to these horizontally oriented support rods, which can be rotated about the support column 45 with the cross member 47.
  • the pack row 28 is fed to the packing station 42 approximately in the middle.
  • the feed conveyor 29 is centered on the support column 45.
  • a number of small packs 21 corresponding to the size of the bundle - arranged in a plurality above one another - is detected by a transversely movable swivel slide 49 acting along a quarter circle and conveyed along a four-part circle on a plate-shaped top track 50 into the packaging position 43.
  • the pivoting slide 49 is connected to a plate forming the upper track 50.
  • the group 30 of the small packs 21 reaches the area of a lifting platform 51. Their most important task is to lower the group from the level of the upper track 50 to the level of a main track 52. This consists of a height opposite the Upper web 50 offset web plate 53.
  • the packaging elements are arranged or effective on the main web 52.
  • the lifting platform 51 consists of a platform 54 on which the group 30 is pushed by the pivoting slide 49.
  • the platform 54 is formed by three sub-platforms, which are supported on a lower, transverse support profile 55.
  • the top of the lifting platform 51 is formed by a platform cover 56, which lies on the top of the group 30.
  • the platform cover 56 is connected to an upper cross bar 57.
  • These and the lower support profile 55 are connected to one another by upright guide rods 58.
  • the guide rods 58 can be moved up and down in fixed slide bearings 59 on the track plate 53.
  • Another special feature of the lifting platform 51 is that its side walls 60 can be moved transversely in order to exert a lateral pressure on the small packs 21 of the group 30. This makes it possible to set the group 30 as the content of the container 20 to an exact, constantly recurring dimension.
  • the side walls 60 are to this Purpose pivoted on pivot arms 61 which are connected to the lower support profile 55 via a pivot bearing 62. When a group 30 is received, the side walls 60 are moved apart. The side walls 60 are then moved towards one another by compressing the small packs 21.
  • the lifting platform 51 In the upper starting position (FIG. 12), the lifting platform 51 is aligned with the platform 54 on the upper track 50. After group 30 has been taken up, the lifting platform 51 is lowered until the platform 54 is aligned with the main track 52.
  • the group 30 is ejected, specifically by a pusher 63.
  • This passes through the lifting platform 51, taking the group 30 with it.
  • the pusher 63 is guided by pushrods 64, which are located below the track plate 53, while the pusher 63 itself moves above it.
  • the group 30 passes through the level of a film web 65 when leaving the lifting platform 51. This is held ready in an upright plane by a film apparatus 66.
  • the film web 65 is carried along by the group 30, a metered blank for forming the covering 31 being separated from the film web 65 by separating knives 67.
  • the blank wraps around the group 30 in a U-shape and is then folded in the manner described above (FIGS. 2-6).
  • This folding takes place in the area of a folding station 68.
  • side flaps 36 lying in the direction of movement are folded by side folders 69 on both sides of the movement path of group 30.
  • the side folders are moved from a forward position of the group 30 into the region of the side tabs 36. These are folded by the side folders 69, the side folders 69 then being conveyed further with the group 30.
  • the group 30 with the wrapping 31 (and with the side folders 69 in the folded position) is conveyed from the already largely fully-folded containers 20 until it abuts against a container row 70, with the container row 70 continuing to move by one movement stroke corresponding to the dimension of a container 20.
  • the pusher 63 then returns to the starting position.
  • the side folders 69 on both sides of the container 20 are moved in the opposite direction to the movement of the container 20, the side folder 69 emerging from the area of the group 30 on the not yet folded back of the wrapper 31 (position according to FIG. 2).
  • the longitudinal flaps 32, 33 can be folded to form the edge strip 35 (folding processes according to FIGS. 3 and 4).
  • An upper folder 71 is provided for the downward folding of the upper longitudinal tab 32, which here consists of a relatively thin wall with a lower angled leg 72. This presses the edge tab 32 onto the lower, projecting longitudinal tab 33.
  • the longitudinal tab 33 rests on a lower folder 73, which also serves as a sealing tool and is therefore heatable.
  • the lower folder 73 is designed as an angular profile piece (FIG. 14).
  • the approximately horizontally directed edge strip 35 lies on an upward leg 74 of the lower folder 73.
  • the edge strip 35 is pressed by the upward movement of the lower folder 73 against the rear longitudinal surface of the envelope 31 or against the longitudinal tab 32 and sealed with it.
  • the upper folder 71 and lower folder 73 can only be moved up and down.
  • the upper folder 71 is connected via holding rods 75 to a support profile 76 which extends transversely above the folding station 68. This is movably supported on the track plate 53 via lateral, upright guide rods 77.
  • the guide rods 77 can be moved up and down in slide guides 78 in the web plate 53 in order to carry out the folding movement.
  • the lower folder is mounted in the starting position below the web plate 53 or the main web 50, so that the leg 74 lies flush with the underside of the container 20.
  • the lower folder 73 is attached laterally to a profile rod 79, which in turn is connected at the ends to guide rods 80. These in turn are mounted in an upright arrangement in sliding guides 81 on or in the track plate 53. Due to its function, the lower folder 73 performs only small lifting movements.
  • the next group 30 is fed with the wrapping 31, the side folders 69 running in the manner described with this subsequent group 30, with the side flaps 36 being folded over.
  • the relative position of the side folders 69 is such that in the end position one is in the direction of movement the front area of the side folder 69 enters the area of the side surfaces of the pack 20 in front in the pack row 70.
  • the side flap 37 on the back in the conveying direction is folded over (FIG. 5).
  • Upper flaps 38 and lower flaps 39 are folded during the further transport of the row of containers 70 by fixed, immovable folding members of a known type, namely by so-called folding switches (not shown). These are designed as fixed walls, which are arranged laterally next to the path of movement of the container 20 and by the curved design of a folded edge during the Fold the movement of the containers 20 one after the other overlap 38 and underlap 39.
  • the side surface is sealed by a plate-shaped sealing tool 82, namely the overlapping regions of upper lobe 38 and lower lobe 39 with one another.

  • the sets 40, 41 can be modified with regard to the type and number of packaging elements.
  • the packaging elements to be exchanged for changing the format of the packaging (bundle 20) to be produced are arranged on a common carrier, namely on the web plate 53.
  • the plate-shaped top web 50 is also connected to the organs attached thereto, in particular the pivoting slide 49 .
  • the common carrier (web plate 53) is easily removable and mounted on holding members in the packaging station 42. It is the horizontally directed support rods 48 connected to the cross member 47, on which the track plate 53 with bearing pieces arranged on the underside thereof 84 displaceable and therefore removable, is stored. To replace a complete set 40, 41, the web plate 53 is pulled down from the support rods 48 in the area of the exchange station 44 and exchanged for another set.
  • the movable packaging members of a set 40, 41 are automatically coupled to stationary, non-exchangeable drives when a set 40, 41 is exchanged or when it is moved into the packaging position 43.
  • drive elements 85, 86, 87 for various movable packaging elements are arranged on the machine frame or on the drive housing 46 on the upper side.
