Definitions
- the invention relates to a method for covering a flat tube made of stretch film over a stack of goods arranged in particular on a pallet, in which a tube section is pretensioned in the circumferential direction and then pulled over the stack of goods in the pretensioned state.
- a stretch film which is completely welded at one end, is gathered like an accordion and placed on rod-shaped holding elements such as plucking fingers of a tensioning frame.
- the holding elements are then moved apart, as a result of which the stretch film is pretensioned in the circumferential direction.
- the tensioning frame is moved downwards along the stack of goods and possibly a pallet carrying the stack of goods, the gathered stretch film being pulled off the holding elements and resting against the outside of the stack of goods and possibly the pallet carrying the stack of goods.
- the gathering fingers can also be designed as gathering corners, whereby each gathering corner consists of a horizontally arranged and angled tube section. The gathering corners correspond to the floor plan of the stack of goods are arranged and their position can be changed along an imaginary line running through the center of the stack of goods and the respective gathering corner.
- the weld seam of the welded end protrudes on both sides of the stack of goods with the formation of two large triangular hoods.
- the ' hoods extend into the corner areas of the stack of goods.
- the hoods have to be fixed either on the sides or on the top of the stack of goods so that the wrapped stack of goods is given a visually appealing wrapper and the pointed or triangular hoods are not damaged during transport of the wrapped stack of goods.
- the fixed hoods also reduce the printable area of the hose section. During external storage, water can also penetrate between the hoods and the film, which is undesirable.
- the object of the invention is therefore to improve the previously known method in such a way that after the tube section has been pulled over, the excess film in the region of the top and / or bottom of the stack of goods or the pallet carrying the stack of goods is as small as possible.
- the tube section is partially open on the upper and lower sides and is pretensioned so strongly that the upper and / or the lower end of the tubular section in the pulled-over state by reaching around at least in the area of the upper and lower side edges of the upper side and / or the underside of the stack of goods or the underside of the stack of goods supporting pallet serves as an abutment.
- the strong pre-tension ensures that the hose section not only abuts the four vertical sides of the stack of goods, but also encompasses the top and / or bottom of the stack of goods or the underside of a pallet carrying the stack of goods, at least in the area of the side edges and in so far as Abutment serves.
- the hose section due to the upper and / or lower end of the hose section, which is designed as an abutment, high vertical stresses, which are indispensable for securing the stack of goods, can be transmitted to the stack of goods.
- the hose section with the appropriate hose material, can still have high restoring forces for re-tensioning if, for example, the grains contained therein are aligned in a space-saving manner when transporting an encased stack of goods consisting of bagged goods and the hose section adapts itself according to the changed dimensions of the stack of goods.
- the upper and / or the lower end of the hose section in the pulled-over state can lie substantially flat on the top and / or the bottom of the stack of goods or the underside of the pallet carrying the stack of goods. Due to the high preload, the tube section lies essentially flat against the stack of goods or the underside of the pallet carrying the stack of goods, so that the excess film in the area of the top and bottom is reduced even more, as in conventional stretching processes.
- the tube section in the state lying around the stack of goods can be stretched by 50% to 80%, preferably by 70%, in relation to the circumference in the non-prestressed state.
- At least the end not to be pulled over the stack of goods can be at least partially welded closed in order to achieve a hood-like configuration of the hose section, so that the hose section is not pulled too far over the stack of goods and the top or bottom is provided with film in the covered state.
- the hose section can be welded at least partially at least partially orthogonally to the longitudinal extent of the hose section.
- At least the two corner regions of the end of the hose section which is not to be pulled over the stack of goods can be welded in, in particular at an angle, in the flattened state, forming weld seams.
- the two obliquely aligned weld seams of the end not to be pulled over the stack of goods ensure that the hose section is not pulled too far over the stack of goods when it is pulled over.
- the amount of film material in the area of the top and / or bottom or the bottom of a pallet carrying the stack of goods is further reduced by the oblique weld seams, so that the contact of the hose section with the top and / or bottom is further improved.
- the weld seams can be arranged in the corner regions of the hose section in the flat state at an angle of approximately 45 ° to the longitudinal extent of the hose section.
- the welded-on corner areas can be arranged in the state of the tube section attached to the stack of goods in the area of diagonally opposite corners of the stack of goods.
- the welding Seam sections aligned along the diagonals of the top or bottom of the stack of goods.
- the end of the hose section to be pulled over the stack of goods and partially welded in the area of the corners of the hose section in the flat state is tensioned more than the rest of the prestressed hose section in order to cover the hose section. This is necessary so that the hose section can be pulled over the stack of goods.
- the pretension in the area of the end to be drawn over the stack of goods is up to 40% greater in relation to the pretensioned state of the hose section.
- z. B. a three-layer film composite can be used as a hose section.
- Such film composites have high restoring forces which are necessary for the application, in particular of vertical tensions, to secure the stack of goods.
- retensioning is necessary even with minor changes to the external dimensions of the stack of goods. B. guaranteed during transport.
- the two outer layers of the three-layer film composite can have a co-polymer component and the inner layer can have an elastomer component.
- the elastomer portion ensures the strength on the one hand and the stretchability of the hose section on the other hand.
- Fig. 1 is a plan view of a plane spanned by gathering fingers hose section in the untensioned and in the pretensioned state to the overdraft ⁇ hen of the hose section over a stack,
- FIG. 2-5 different embodiments of a hose section
- FIG. 6 shows a plan view of a stack of goods encased by means of a tube section, the opposite weld seams or weld seam sections running along a diagonal of the top of the stack of goods.
- the gathering fingers 2 are designed as gathering corners, each gathering corner consisting of a horizontally and angled tube section.
- the hose section 1 has two opposite weld seams 3 at one end.
- the hose section 1 is open between the two weld seams 3 on the edge.
- the hose section 1 is shown in solid state with solid lines.
- Large triangular film excesses 4 are formed on the two narrow sides and originate from the plucking fingers 2.
- the gathering fingers 2 are moved in the direction of the arrows 5 shown in dashed lines into the position 6 shown in dashed lines.
- the circumference of the hose section 1 is increased considerably.
- the excess film 4 still present in the untensioned condition disappears completely.
- the hose section 1 is then pulled over the stack of goods, not shown.
- the gathering fingers 2 are moved vertically along the stack of goods in the immediate vicinity and at a short distance, so that the gathered hose section 1 is pulled off the gathering fingers 2. Due to the strong preload and the high restoring forces, the hose section 1 does not only attach to the four vertical sides of the stack of goods. Rather, it also encompasses the horizontal side edges of the top and / or the underside of the stack of goods or the underside of a pallet carrying the stack of goods at least in the region of the side edge and lies flat there.
- FIG. 2 shows a hose section 1 which has edge-side weld seams 3 which run orthogonally to the longitudinal extent of the hose section 1.
- FIG. 4 shows a hose section 1 which has weld seams 7 directed obliquely towards the respective end only in the two corner regions, while the end of the hose section 1 is otherwise open.
- two oblique weld seams 7 are provided at both ends. It is obvious that in order to pull the hose section 1 over, the end to be pulled over the stack of goods has to be prestressed in relation to the prestressed state of the remaining hose section 1. This additional tension, which essentially depends on the size of the stack of goods and on the length and orientation of the weld seams 7, can be up to 40%.
- FIG. 6 shows a top view of a stack of goods 8 which is enveloped by a hose section 1. As can be clearly seen, the edge-side weld seams 3 of the hose section 1 run along a diagonal of the top of the stack of goods 8.
