Definitions
- the invention relates to a rectangular, accessible transport pallet that can be produced from at least two interconnectable corrugated cardboard blanks, in which the blanks can be at least partially connected to one another, and are arranged with respect to one another in such a way that the directions of their corrugations intersect, the first blank is foldable and shaped along a pair of opposite pallet edges extending, support beam-like edge girders, which are essentially open on their side facing the other, second blank and can be inserted into the supporting elements, and between the two edge girders has at least one inner, support beam-like support channel, on the second cut in the Substantially over its entire length along its edges assigned to the opposite supporting beam-like edge girders, bendable spacing sections corresponding to the pallet height are arranged and the supporting elements are arranged opposite one carrier surface of the pallet-forming main surface of the second blank are deformable.
- a flat and undeformed corrugated cardboard pallet which forms the second blank and determines the surface of the pallet, is connected practically in a flat manner to the first, three carrier bars defining blank by covering flat parts directed against the second blank between the three support bars and a foldable edge flange on the outer spars of the first blank with glue and pressing the second blank onto the first.
- An exclusively non-positive connection is thus provided between the two blanks.
- the support elements in the form of upright reinforcement pieces are inserted into the hollow interiors of the support bars, which are folded in a zigzag pattern and thus extend between opposite walls of the interior of the support bar.
- These reinforcement pieces are held at their ends in the support bars by means of tabs and preferably have a somewhat greater height than the support bars, so that their upper edges are slightly compressed when the second blank (upper part) is pressed on, i.e. be deformed.
- the known pallet thus requires a total of five material blanks and high forces when the blanks are pressed together to deform the reinforcements, these forces easily leading to deformations of the shaft material of the first and second blanks and impairing their load-bearing capacity.
- This range offers only insufficient resistance to lateral deformation forces (shear, bending and torsional stresses), so that it is unable to cope with the stresses that occur in practice, especially during the usual careless handling in the factory with forklifts and similar equipment.
- undercarriage is only possible in the direction of the support bars.
- U-shaped supporting parts may have to be inserted in the center parallel to the edge supports of the side edges, as shown in an optional embodiment of that known construction , which means additional material and manufacturing costs.
- the box-shaped connecting elements only remain connected to the actual support plate along a single crease line in the edge area.
- This already very fragile edge area is further weakened by the adhesive tabs. All forces are transferred here, especially in the central area of the pallet, where the greatest moments occur, for example, when bumping from the side, solely via the fold lines from the upper part to the lower part and vice versa.
- the assembly turns out to be relatively unfavorable for these edge connecting elements, which cannot be fastened to one another and have their only counter bearing in the channels.
- the punching out of the internal cutting lines of the flaps must be carried out extremely precisely in order not to weaken the stamping Create fold line. In the length of the pallet there is a waste that goes beyond the actual usable length practically around the height of the side flaps. A connection between the upper and lower part the interior of the pallet to achieve sufficient torsional rigidity is completely absent.
- the invention is based on the object to provide a material-saving, easy to assemble as well as torsion-resistant and kink-resistant, in various directions accessible under the range described in the flat state, i.e. a convenient form of space, delivered by the corrugated cardboard processor to the user and in this in a simple and can be erected quickly and reliably in a cost-effective manner, in particular by machine, in large numbers.
- the support webs can be punched out of these, articulated on one side foldable via crease lines, without significant weakening of the main supporting surfaces of the blanks, in such a way that they engage in corresponding recesses on the other blank by means of fastening lugs.
- the shape of the blanks is provided in such a way that no undercuts occur in spite of the box profiles of the edge supports and support channel, which determine the strength, so that the blanks can be produced and largely prepared on conventional corrugated cardboard processing systems so that they are flat, transport-friendly Can be delivered in a state that can be continuously erected and assembled by the user (consumer) using simple mechanical means.
- the ease of transport results from the rectangular basic shape of both blanks without connecting tabs or the like which are outstanding over their contours.
- the pallet can optionally be driven under on all sides and that the edge girders, the inner support channel and those extending into the edge girders Spacer sections have recesses to form loading openings. As will be shown below, these loading openings can be realized without impairing the load capacity of the pallet and can even be used for further stabilization measures.
- the edge supports, the inner support trough and the spacer sections are provided with recesses for the fork of a forklift or lift truck, provided that openings are provided in the outer surfaces of the edge supports and openings are aligned with the openings in the edge support inner surfaces and in the support trough, while, with Breakthroughs and openings in alignment, which are at least partially determined by punched-out support flaps articulated about vertical axes, the width of which essentially corresponds to the inner width of the channel-shaped edge girders and which can be folded into the latter as well as therein are lockable.
- the weakening in the side surfaces which is required for the purpose of forming forklift openings, is practically compensated again by not simply cutting out the windows, but instead using the punched-out parts for supporting purposes in relation to the other blank part, the supporting flaps preferably being used extend over the entire height of the edge beams and thus have a vertical support.
- the inner support channel is more central, third (DE-AS 11 07 499) Carrying spar provided and practically forms the central axis of the pallet.
- the support webs can preferably be arranged on the second blank carrying the spacer webs and engage in the open edge girders and, if appropriate, the inner support channel.
- the support webs can expediently be arranged on corresponding positions on the edge supports or the support channel and essentially correspond in width to that of the edge support or support channel, so that they have the box shape of the edge support or support channel both vertically and horizontally support and thus contribute significantly to the high rigidity of the pallet.
- the forklift openings can extend downward from the upper edges of the inner edge surfaces or the support channel and can be cut out (punched) on three sides from the main surface of the blank such that the cut-out parts serve as tongues in the plane of the connection with the other blank Main area between the edge beams or the support channel remain.
- the punched-out part extends with the folded edge support or folded support channel beyond the creases required for folding into an area above the respective channel and thus extends the area, which results in a significantly increased stiffness.
- the recesses can be used even better to increase the overall pallet production and the parts to be cut free for their production can also perform a vertical support function in addition to a horizontal holding function for the edge supports and support channel, it is furthermore provided that the openings in the outer surfaces of the edge supports are at least partly by punched-out, pivotally articulated support straps are determined, the width of which essentially corresponds to the inner width of the edge girders and which can be folded into the latter and can be positively locked with the inner surfaces. It is advantageous if the support tabs can be non-positively and / or positively connected to the support flaps, which results in an even more intensive connection between the two blanks and a significant increase in the diagonal stiffness.
- connection can be done by gluing, stapling, hooking or similar conventional measures.
- interconnected support straps and support flaps can be locked by support webs of the second blank which are arranged in this area and can be folded into the edge supports.
- the waves of the material in the blank comprising the edge supports and the support channel can preferably run in the transverse direction of the pallet and in the other blank carrying the spacer sections in the longitudinal direction.
- the transverse course of the shaft in the cross-section comprising the edge girders and the support channel in turn results in an optimal load-bearing capacity of the edge supports and the support channel as well as the support tabs in the vertical direction and the possibility of absorbing high belt moments in the main surface.
- predetermined breaking points of a defined width can be provided on at least one of the blanks, preferably on the second blank and in the area of the windows or loading openings. This can cause damage that otherwise occurs when strapping the goods stacked on the pallet can be largely avoided with metal or plastic tape by pulling it onto the pallet, because when the fastening or holding tapes are placed at the predetermined breaking points, these areas are raised to the defined width when the cargo is moved inwards and also as edge protection for the cargo serve without further tearing of the pallet outside the predetermined breaking points.
- the blanks can preferably consist of multi-layer, preferably two-layer corrugated cardboard. With this choice of material, you will have to balance the strength requirements of the pallet with the weight and cost of the corrugated cardboard material used for it.
- the transport pallet according to the invention is preferably produced semi-automatically or fully automatically, since manual erection does not result in the weight of the blanks for the usually required pallet sizes, because of the bulkiness of the blanks and with regard to the necessary folding forces or the restoring forces resulting from the material Comes into consideration.
- the first blank having the edge carriers can be pre-broken in stages in a folding and pressing station, first the first edge carrier, then the support channel and finally the second edge carrier being pre-broken, and its surfaces directed against the other, second blank can are sprayed with glue while at the same time breaking the spacer sections of the second blank, whereupon the latter is then placed on the first blank or inserted with the spacer sections into the edge girders, as well as pressure from above and laterally on the parts supported according to the shape of the edge girders and support channel can be exercised.
- the process thus involves the blank comprising the edge girders and support channel being broken in three stages and then provided with the adhesive at all required points, while at the same time the other blank is being pre-crushed, so that the time required for the assembly can be kept relatively short and only one for this manufacturing process , two people are required.
- the supporting webs and, if appropriate, the supporting flaps and flaps, the latter preferably being pressed into their locked supporting position by means of gluing, stapling, hooking or the like, can advantageously be pressed, which can be done manually or automatically on another machine station.
- a system is advantageously proposed in which a first erection station is used to gradually break the first blank, which has the edge girders and the support channel, and to apply glue to this pre-broken blank, to pre-break the spacer sections of the other, second blank and a second erection station is provided for the folded joining of the two blanks.
- Such a system can be comfortably operated by one or two people, the first and second erection stations being semi-automatic machine units. These can be produced with a reasonable amount of design effort and make a significant contribution to the economic realization of the object on which the invention is based.
- the first erection station can be equipped with stops, alignment strips or similar positioning elements Troughs for receiving the to be folded or folded edge supports and support trough of the first blank equipped support table and a press ram over one of the troughs, preferably the central trough.
- the press ram is preferably provided in such a way that it interacts with press elements which can be swiveled in laterally as a counter-form for overpressing the preliminary break, as a result of which the restoring forces of the material used can be effectively prevented.
- the second erection station can advantageously include form-changeable supports for receiving the pre-folded blank on the second erection station, wherein these supports can be movable from an essentially trapezoidal starting position into an essentially rectangular press position. So that the second erection station is designed so that the pre-folded on the first erection station can be accommodated comfortably, its regression is taken into account due to the restoring forces, but at the same time it can be deformed into the position required for the finished pallet.
- the latter can comprise a glue slide which can be moved in one of its main directions, preferably its longitudinal direction, above the supports, this glue slide acting vertically in accordance with the placement position of the blank and thus the position of the adhesive surfaces inner glue nozzles for the adhesive surfaces of the blank and inclined to act outer glue nozzles for the inner sides of the outer walls of the edge supports and the support tabs thereof.
- a pressure stamp designed as a flat plate is provided, which can be moved from its rest position into a working position directly above the support moved in a rectangular press position, while still lateral pressure plates of the supports in a vertical position and thus in a surrounding the pallet from the side of the edge beams horizontal press position are movable.
- a pre-crushing device for the spacer sections can be arranged on the side of a frame of the second erection station.
- a pallet is formed from essentially two blanks, the formation of which is extremely machine-friendly with respect to the folding operations to be carried out and their processing is thus possible on a continuously operating machine.
- the cuts do not form any undercuts, and they can be unfolded in only one direction.
- the sheet-like connection of the two blanks in combination with the box-shaped support bars and the support webs as well as other support elements and flaps results in a high torsional rigidity and thus a load capacity, which such pallets are particularly suitable as disposable pallets, which only need to be erected by the loader makes, although multiple use is also possible.
- a pallet 1 constructed according to the invention from corrugated cardboard (FIG. 1) essentially comprises a first blank 2 and a second blank 3, both consisting of corrugated cardboard and provided in such a way that their corrugation directions (see FIGS. 2 and 3) are in the finished pallet Cross 1.
- the first blank 2 forms the base, especially with respect to the main or loading surface of the pallet, and the second blank 3 forms the top layer.
- loaders 41 and loading openings 42 in the longitudinal or transverse direction - known per se from conventional pallets educated.
- the first blank 2 can be unfolded from a substantially rectangular corrugated cardboard blank into the shape shown in FIG. 2, with sufficiently well-known folding and folding lines, for example crease lines (dashed or shown in thin lines), being provided for the folding at corresponding folding points, such as they are common in the corrugated cardboard industry.
- support beam-like edge supports 21 are formed on the first blank, which have a U-shaped or channel-like shape have and determine outer surfaces 21a and inner surfaces 21i.
- a support channel 22 constructed in a similar manner, which is also designed and acts in the manner of a support beam, is provided.
- the rectangular passages or loaders 41 which extend in the longitudinal direction of the blank and thus the finished pallet, into which the forks of a forklift truck, pallet truck or the like. can intervene for the purpose of lifting and / or transporting the pallet 1.
- openings 24 are made in the outer surfaces 21a in the direction of the width of the pallet, and openings 25 are made in the inner surfaces 21i and in the side walls of the support channel 22. Openings 24 and openings 25 together form the loading openings 42.
- the openings 24 are recesses delimited by support tabs 28, the width of these support tabs corresponding to the width of the edge supports 21 and having lugs 29 on their free vertical edges with respect to a vertical pivot axis (not designated) which enter into slot-shaped recesses 23 in can snap the inner surfaces 21i.
- the openings 25 are formed by three-sided punching of tongues 26, which remain firmly connected on one side with the cutting material and extend from the folding or crease lines provided for the edge support 21 or the support channel 22 such that these tongues when folding the edge support and support channel 26 form an extension of the main surface of the unfolded blank 2, which main surface forms an adhesive surface 27, beyond the fold lines.
- the tongues 26 and thus the openings 25 are dimensioned such that the tongues 26 practically cover the entire support channel 22 and mutually opposing tongues 26 butt, so that a quasi-closed surface is created in this area.
- the protrusion of the tongues 26 over the fold lines for the edge girders and the support channel contributes significantly to an increase in the load-bearing capacity, in particular the resistance to buckling and torsion.
- the tongues 26 located above the edge supports are provided with a circular recess 26a corresponding to the pivoting radius of the support tabs 28.
- the second blank 3 also consists of a stamped blank which is rectangular in its outer contours and, corresponding to the edge supports 21 of the first blank, has angled foldable spacer sections 31 along its longitudinal edges, the height of which, in conjunction with the corresponding outer surfaces 21a of the edge supports 21, essentially corresponds to the height of the pallet 1 certainly. These spacer sections 31 abut against the outer surfaces 21a when the pallet is assembled.
- the second blank 3, as can be seen from FIG. 3, essentially forms the shape of a flat, inverted U in the unfolded state, the legs of which are determined by the spacing sections 31 and the web of which forms a main surface 34, which is the area connection with the first blank 2 serves.
- windows 35 are provided in the spacer sections 31 by pre-punching during the manufacture of the blank, which are initially closed by support flaps 36 stamped free on three sides and articulated via one-sided fold lines.
- these flaps 36 are opened and connected to the support tabs 28, for example by gluing or stapling, and locked in the slots 23.
- the support flaps 34 are designed as horizontal support webs, and their width is dimensioned such that they extend over the entire width of the edge supports 21 and into the slot-shaped recesses 23 provided in the inner surfaces 21i Help can be provided by noses 33 provided on them.
- the width of the vertical support webs 32 corresponds essentially to the width of the edge supports 21 or the support channel 22, and the support webs 32 are arranged at the positions of that channel corresponding points of the second blank 3, so that the support webs 32 are folded into the channels and their Lugs 33 can engage in the slot-shaped recesses 23.
- the support webs 32 can lie tightly against the side walls of the grooves of the edge supports 21 or the central support beam 22, although their main direction of loading is the vertical.
- the corrugation direction of the corrugated cardboard runs in the longitudinal direction of the blank, so that the wave course in the vertical support webs 32 is vertical and in the horizontal support webs 36 horizontally, which results in corresponding, optimal load conditions .
- the shaft runs in the transverse direction, which means that the edge supports 21 and the support channel 22 and the support brackets 28 can be loaded vertically, and high bending moments in the main surface 27 with the tongues 26 can be absorbed.
- the inner support webs 32 on the edge are somewhat narrower than the others, so that a sufficient edge web (not designated) remains above the window 35 to delimit the same.
- FIG. 4 A variant of the second blank 3 is shown in FIG. 4.
- the spacer sections 31 of the embodiment of FIG. 3 are formed by box-shaped, rectangularly folded support elements 37, which therefore have a higher section modulus than the straight-spaced spacer sections 31.
- the width of these box-shaped support elements 37 corresponds to the internal dimensions of the edge supports 21, so that the support elements 37 can easily be inserted into the edge supports. If the support elements 37 run continuously over the entire length of the second blank 3, the tongues 26 need not be formed in the region of the outer edge supports of the first blank 2.
- the two blanks 2 and 3 provided with the necessary punchings and folding lines, can be delivered to the user in a flat state by the corrugated cardboard manufacturer, so that there is a minimal transport volume for this transport and the parts can be stored in a space-saving manner until they are used.
- the parts prepared in this way are then erected, for example, on a semi-automatic erecting device, as shown in FIGS. 5 and 6, according to the diagram in FIG. 7 into the shapes shown in FIGS. 2 and 3 and 4, respectively. These are put together in pairs, so that the final shape of the pallet 1 results.
- two erection stations 5 and 6 can be seen, in addition to which, advantageously in the vicinity of the respective first processing station, are the first blanks 2 and second blanks 3 delivered on pallets by the corrugated cardboard producer.
- the first erection station 5 serves for the gradual pre-breaking of the first blank 2 in the order of the stages I, II and III shown in FIG. 7, namely in accordance with the crease lines, which in the initial stage I and in the left part of the stage II as solid lines 20 shown and are attached by the corrugated cardboard producer.
- the first erection station 5 comprises, on a frame 50, a support table 51 which is equipped with stops, straightening strips or similar positioning elements (not shown here) and with channels 52. The latter also serve to align and accommodate the edge girders of the first blank 2 which are to be folded or folded step by step in accordance with I, II and III (FIG. 7).
- a pre-breaking device 64 is provided for the spacer sections 31 of the second blank 3, while on the frame form-changeable supports 61 and side pressure plates 611 cooperating with them, which can be moved by means of pressure cylinders 612 according to the arrows E, are arranged.
- the shape-changing pads 61 are movable from a trapezoidal starting position A shown in solid lines, which corresponds to the shape of the pre-cuts of the blank 2 in stage III, into a rectangular press layer B shown in dashed lines, with the purpose of holding or pressing during Assembling the blanks, the side pressure plates 611 are moved according to arrow E into the position also shown in broken lines. However, before this movement takes place from the trapezoidal starting position A into the pressing position B, the blank 2 placed in the supports 61 is sprayed with glue.
- a glue carriage 62 which can be filled from a glue container 7 arranged near the second erection station 6, is arranged on the frame 60 so as to be movable in the direction of arrow L (FIG.
- the glue slide 62 comprises inner glue nozzles 621 and outer glue nozzles 622.
- the inner glue nozzles 621 are used for spraying glue on the main surfaces 27 of the blank 2, the outer, inclined glue nozzles 622 for applying glue to the inner sides of the outer surfaces 21a of the edge supports 21, including the support tabs 28.
- the main surfaces lying against one another can be provided with glue in the form of points, lines or planes and thus glued to one another.
- glue in the form of points, lines or planes and thus glued to one another.
- predetermined breaking points 80 defined by perforations can be formed in the edge region above the windows 35. These predetermined breaking points 80 tear in a conventional manner when the loaded pallet is strapped, if the load does not protrude beyond the edge of the pallet, and form an edge protection. The strapping is passed through the loading openings 42.
- the two blanks can be fastened to one another by means of staples, as long as a sufficiently intimate connection between the two blanks is achieved and the cross-shaft connection is effective.
