Definitions
- the invention relates to a method and a device for wrapping a stretch film around a container or packaged goods package, which comprises at least three round containers which are positioned and held on a holding device while the stretch film is being wrapped around the container.
- the film is wrapped around the rectangular individual packaging, which is preferably in a rectangular arrangement.
- This device has a winding arm, which is rotatably mounted about a vertical axis and carries at its free end a supply roll of the stretch film, which must therefore be guided around the container while it is being wrapped around, which requires a relatively high level of mechanical complexity.
- the containers are well supported as a result of the outer walls lying flat against one another, so that a relatively well-positioned and firmly held structure is present, especially when the individual containers are still attached to the Holding plate placed on top of the container can be fixed relative to one another. Wrapping the stretch film around such a container does not pose any particular difficulties, apart from the increased mechanical expenditure.
- the invention is essentially based on a device according to DE _ 39 02 919 AI the task of creating a method and an apparatus for the simple and reliable production of container bundles held together with a stretch film from round containers, in particular to avoid costly and fault-prone pliers system, the actual hose winding process is to take place in the non-stretched state of the film.
- Figure 1 shows a simplified schematic representation of the inventive device for performing the new method.
- Figures 2 to 7 show a schematic representation of the procedure when performing the inventive method.
- FIGS. 8 and 9 show top views of the spreading device forming part of the device according to the invention in two different positions.
- Figure 10 shows a section along the line X -X in Figure 8.
- Figures 11 and 12 show a schematic representation of the manner in which the stretch film is transferred to the end winding.
- FIG. 13 shows a side view of the container produced according to the invention
- FIG. 14 shows a bottom view of the container produced according to the invention.
- a stretch film supply roll 2 is rotatably mounted in the schematically illustrated machine frame 1.
- Gene stretch film 3 is wound on a cylindrical winding drum 5 driven by a motor 4, the circumferential surface of which has four openings 6 distributed over the circumference at uniform intervals, which extend in the axial direction at least over part of the winding drum.
- a spreading device 8 is mounted, which can be moved back and forth between the winding station I and the packaging station II in accordance with the arrows fl and f2 in the vertical direction and in accordance with the arrow f3 in the direction with the stretch film packaging or to be wrapped round containers 9 are combined, for example, in bundles of six pieces.
- the spreading device 8 comprises a support column 10, at the lower end of which a mounting plate 11 is fastened.
- a toothed pinion unit is rotatably mounted on the column 10, which comprises a toothed wheel 12 and a conical toothed wheel 13 which can be driven alternately via conventional gear elements.
- the toothed wheel 12 serves to drive two toothed rack units 13 in opposite directions.
- Each toothed rack unit 13 contains a link block 15 which can be displaced along a guide rail 14 fastened on the mounting plate 11.
- Each link block 15 is adjoined on one side in the direction of the central drive gear 12 by a strip 17, which on the inside is connected to an inner rack section 18 that meshes with the central drive gear 12 is provided.
- Each pinion 36 is rotatably mounted on axles 24 carried by the mounting plate 11, which are arranged in the corner points of an ideal rectangle.
- Each pinion 36 is rigidly connected to a swivel arm 25 which carries a freely rotatable expanding mandrel 26 at its free end. With the described and illustrated gear elements, these expanding mandrels can be pivoted along circular paths between the positions “Z” and “Y” shown in FIGS. 8 and 9.
- a hose section dependent on the height of the containers 9 to be packaged is wound onto the winding drum 5, preferably in multiple layers.
- the spreading device 8 is then moved from the winding station I into the packaging station II, in which a container to be packed, for example made up of six containers 9, is placed.
- the hose section 27 is placed around the six containers 9 in the manner illustrated in FIG.
- positioning and holding elements 28 are attached to the underside of the mounting plate 11, which are brought to bear and pressed against the top of the containers 9 when the spreading device is lowered.
- the outward-pointing double arrows indicated in FIGS. 3 and 6 indicate the position of the rack units 13 shown in FIG. 9;
- the inward-pointing double arrows shown in FIGS. 4 and 5 indicate the position of the rack units 13 according to FIG. 8.
- Figures 8 and 9 show that the axes 24 are eccentric to the axes of the outer container 9, the position of which is illustrated by the dashed lines. It is thereby achieved that the expanding mandrels 26 approach the containers 9 during their inward movement into the gusset-like free spaces located between adjacent containers and possibly come into contact with these, the prerequisite for this is that the expanding mandrels are then produced again without damaging the stretch film Package containers can be pulled out.
- FIGS. 11 and 12 show an auxiliary device for applying a free end of the stretch film 3 to the winding drum 5.
- This auxiliary device contains a film transfer element 29, which can be moved back and forth between the supply roll 2 and the winding drum 5 in the direction of the double arrow f4 front free end has a suction head 30 which can be acted upon alternately with suction air.
- the winding drum 5 also has a suction chamber 31 which can be acted upon by suction air in order to build up a suction air flow which is effective on the circumference of the winding drum 5.
- the end of the film wound into a tube section can be fixed to the wound tube section by means of glue application or by means of a weld seam in order to support the adhesive forces inherent in the stretch film.
- FIG. 13 shows that in the finished package or container bundle 33, the containers 9 are covered by the stretch film over a substantial part of their height.
- position-stabilizing holding means 34 are attached between adjacent containers 9, preferably by applying a thermoplastic adhesive or the like.
