Definitions

  • the invention relates to a packaging device for large-sized, cuboid, cuboid objects stacked next to and on top of one another, in particular containers consisting of cigarette sticks, with a conveying device for tubular film to a cutting and welding station for separating and closing a film section on one side, and a device for opening the film section , a step-by-step turret, which has a holding device for the open film section for each switching station, which limits a receiving space for a container, a device provided in the insertion position of the turret for inserting the container into a film section, and a welding station for closing the unwelded end of the one end closed by a weld seam, filled with the film section.
  • the product thus taken up by the bag-like tubular film section is transported by means of a conveyor belt to a station, where the bag is evacuated and also closed at the still open end.
  • This facility is designed for perishable food such as meat, etc. to be packaged.
  • This device is not suitable for packaging containers made of cuboid objects such as cigarette sticks, especially if they are to be designed to be as space-saving as possible.
  • the object of the invention is to provide a packaging device of the type mentioned at the outset which, in a space-saving and simple manner, enables film sealing and cartoning of containers.
  • the conveying device for tubular film can be conveyed horizontally lying flat in the cutting and welding station in a length required for the film wrapping plus a film protrusion from which the film section onto the holding device in the insertion position for a container in the conveying direction of the Tubular film is displaceable
  • the device for inserting the container comprises a collecting station for flat, cuboid objects for assembling the container, the ejection position of the revolver for pushing out the filled film section is offset by 90 ° to the side with respect to the insertion position, and the welding station for closing the unwelded end , which is arranged between the ejection position of the revolver and an insertion position of a cartoner designed as a conveyor, with un engaging in the film overhang on opposite sides thereof d extendable tensioners is provided.
  • FIG. 1 and 2 show, in perspective, schematically and in detail, a cartoner for cuboid stacks of cigarette sticks.
  • the cartoner shown comprises an elevator conveyor 1 which is driven step-by-step and which forms a shaft corresponding to the width of an erected carton blank 4 by means of two oppositely arranged groups of belts 2, which are designed in particular as toothed belts and are each guided around upper and lower deflection rollers 3. If necessary, support rollers (not shown) for the belts 2 can be arranged between the standstill positions of the elevator conveyor 1.
  • the carton blanks 4 are taken, for example, from a carton blank magazine and in a carton erection station (as is known, for example, from German patent application P 42 10 813.6) to form a hollow body with a rectangular cross section that is open on both sides, possibly with the gluing of corresponding overlapping parts, and then erected to be inserted into the shaft between the belts 2 of the elevator conveyor 1 by means of a corresponding slide in a standstill phase of the elevator conveyor 1 in its lowest position, namely between holding strips 5 which are attached to the belts 2 and the erected cardboard blank 4 grasp the underside and top and thus keep the erected cardboard blank 4 erect such that the outer and inner tabs 6 or 7 and 8 or 9 located on the circumferential side wall area are used for closing the cardboard at the bottom and top, laterally opposite the elevator conveyor 1 survive.
  • a carton erection station as is known, for example, from German patent application P 42 10 813.6
  • the vertically extending tabs 6 and optionally 8 of the erected carton blank 4 are slightly exposed to the outside by corresponding guide strips (not shown).
  • the bottom-side, horizontally extending tabs 9 are also folded inwards by 90 ° in a vertical position to form a bottom by means of appropriate folders (not shown).
  • a large-sized container 10 to be picked up from the cardboard blank 4 (a cuboid block made of cigarette sticks 11) is pushed from the head side into the cardboard blank 4 that is set up by means of a slide (not shown), the container 10 being countered by the associated folders at that moment in their position turned by 90 ° inward brackets 9 is pushed as a stop.
  • the upper and lower tabs 7 on the head side are then closed.
  • the now filled and closed carton 13 When transported to the fourth position from below, the now filled and closed carton 13 initially runs in its central region against the ends of two (wet or self-adhesive) adhesive tapes 14, each of which is provided by a corresponding adhesive tape feed 16. During further transport, the respective adhesive tape 14 is guided along the seam between the two pairs of adjacent outer tabs 6 and 8 and pressed on by means of a correspondingly pre-tensioned roller 17. After the carton 13 has been passed through, the respective adhesive tape 14 is cut to length and the free end is folded onto the side of the carton 13 located below by means of the roller 17.
  • the finished carton 13 is conveyed from the fourth position into a fifth and ejection position. From this ejection position, a pivotable ejector 18, which engages on the side of the carton 13 located below, rotates the carton 13 by 90 ° onto a conveyor belt 19.
  • the containers 10 are packaged in a tubular film 20 for protection against moisture and are welded therein.
  • This is fed by a bobbin 21 in a flat state, in which the tubular film 20 is provided with a wrap on both sides, gradually fed via rollers 22 to a welding and cutting station 23 lying in a horizontal plane, where a film section 24 of the flat lying tubular film 20 on the is welded and cut off in the conveying direction at the rear end by means of corresponding jaws 25 which can be moved and closed towards one another.
  • the step-by-step driven turret 27 comprises a turret disk 28 which extends perpendicular to the conveying direction of the film section 24 and which has a total of four substantially rectangular recesses 29 distributed uniformly over the circumference.
  • the turret disk 28 carries strips 30 extending perpendicularly thereto in an arrangement such that a stack 31 of cigarette sticks 11 to be filled into the cardboard blank 4 that is set up fits through the recess 29 delimited by four strips 30 at the corners .
  • the strips 30 can in particular be designed as angular strips and optionally as spreading strips. However, they can also form inwardly spring-loaded strips or pairs of strips, which are spread apart by inserting a container 10.
  • the turret 27 now rotates a step division into a transfer position to the elevator conveyor 1.
  • a conveyor 34 which acts on the underside, for example, the filled film section 24 is transported in the direction of the elevator conveyor 1 and, on the way to it, engages in the area of the conveyor which is reverse with respect to the transport direction Foil section 24 above and below an angular tensioner 35 each.
  • the tensioners 35 are then moved vertically apart, so that the rear end of the film section 24 is stretched vertically in the region of the film projection 24a, so that there are two adjacent, vertical edge regions of the film projection 24a, which are welded by means of two horizontally movable and vertically extending welding jaws 36 (the clamps 35 being pulled out of the film projection 24a shortly before the welding jaws 36 are closed).
  • the container 10 thus formed, hermetically enclosed by the film section 24, is then inserted into the cardboard blank 4 already provided in the elevator conveyor 1.
  • the bundles 10 can also be formed on both sides of the elevator conveyor 1, the bundles 10 then being formed on both sides of the elevator conveyor 1, for example from rods 11 of different cigarette brands.
  • a pickup can also be assigned to the slide for inserting the container 10 on the opposite side, the pickup possibly being used as a slide and the slide as a pickup when inserting from the other side.
  • the conveyor 1 can also convey horizontally, although an elevator conveyor is particularly advantageous because of its small space requirement.
  • Electric drives are suitable as drive units for the individual parts. On the one hand, this offers the possibility to change the format dimensions via programming and, on the other hand, to optimize the movements (controlled by stepper motors) through the program and thereby increase the performance.
  • the cartoner enables an at least essentially symmetrical and thus structurally advantageous and successive arrangement of folders, glue nozzles, adhesive tape feeders and the like. on both sides of a step-by-step, simply constructed conveyor, so that the individual components are easily accessible so that malfunctions can be easily remedied.
  • erected cardboard blanks and / or packs to be packed can be fed alternately to the conveyor from two opposite sides, for example.
