Method of stacking pallets and support frames to carry out the procedure.

The invention relates to a method for stacking one on top of the other of pallets and similar devices or containers like them can be used in various fora in transport and storage technology. The subject matter of the invention also includes a support frame for stacking such pallets and containers on top of one another or similar.

Stacking pallets and containers on top of each other is one thing essential prerequisite for the high-grade and rational utilization of storage and transport facilities, especially for the efficient use of the floor space of such systems, which is burdened with high general costs. Ee are therefore already numerous Stacking method and associated auxiliary equipment proposed been.

Such a procedure provides, for example, the use of regal » like, open and free-standing storage racks in front of «the« ine Number of arranged one above the other at a corresponding distance and Compartments or shelves each holding one pallet

exhibit. The use of such facilities has the disadvantage that with only partial loading of the frame a comparatively large proportion of the built-in rack space remains unused, which worsens the degree of utilization of the system. In addition, institutions of this type must generally be based on their own foundations be built up so that the floor space compared to the usable The pallet base is not insignificantly larger. This also leads to a poor degree of utilization of the System footprint.

Another stacking method is based on the attachment of four vertical support posts at the corners of a usually rectangular or square pallet, with the stackable pallet being placed on the upper ends of the support posts and so on. The holding and securing of the position of the pallets is, however, quite insecure with such facilities, especially with greater stack heights. This is particularly disadvantageous when picking up and setting down individual pallets or pallet joints with the aid of forklifts and similar transport machines.

The object of the invention is therefore to create a stacking method for pallets and an associated auxiliary device which can be used to overcome the disadvantages mentioned in the Löge Bind. The erfindungegemäße stacking method for achieving this object is characterized primarily by daö to ims upper U »- fang edge of a first palette zusasieenlegbarer, upright and the rare surfaces of the pallet according to above

attached extending support frame and then placed another pallet on the top of this support frame will.

Oils according to the invention for stacking pallets and the like on top of one another are mainly characterized by releasably interconnected frame sections which are provided for upright attachment along the upper peripheral edge of a first pallet and which extend the side surfaces of this pallet upwards. Whereby the upper side of the support frame is intended for the placement of another pallet. This stacking device is suitable for use on rectangular pallets

and can be attached as an extension of the pallet seldom walls. The horizontal upper edges of the frame sections are in pairs ^ opposite one another! legend with supporting flanges 14 or stop strips 15, which together form a receptacle for a pallet 16 following up in the stack (Fig.l). At the upper edge of the latter, in turn, a support frame composed of corresponding frame sections can be attached to accommodate a further pallet. On these catfish stacks of practically any height can be put together. There." Picking up and setting down individual pallets or partial stacks of pallets can be carried out without difficulty with the aid of conventional forklifts which have appropriately adapted carrying and gripping tools. Individual pallets can be lifted and put on with the attached support frame or by themselves.

The construction of the support frame according to the invention and in particular the sliding connections between the frame sections can be seen in detail from FIGS. Thereafter, the vertical corner posts of the frame section 10 are designed as hollow profile frame bars 17 with a rectangular or square cross-section and a longitudinal slot 16 arranged in the end face of the frame section. The longitudinal slot 18 has a wedge-shaped, widened, lower end section 16a and an "L-profile frame tab 20" is provided for vertical attachment to a strip-shaped profile flange 19, ⁴ 'which the latter forms the vertical corner post of the adjoining fiahmenabechnlttes 11.

Duroh the cutout of the profile flange 19 at the lower end of the rod is achieved that the pallet can engage positively in the profile of the frame rod 20 and as a safeguard against relative displacement between the support frame and the pallet acts, Ia individual the height of the lower cutout can be possessed in such a way that the vertical rod 20 is not supported in the vertical direction on the lower pallet 13, but directly on the floor area below or the supporting frame below it the range of weight of the stack above entl knocks.

In particular, reference should be made to the following KoxistruktlcmsaierlQaale. The stop bar 15 of the Rahoenabschnltts 11 is formed by an angle profile bar, which is two-kaSSig immediately old the vertical frame bars 20 is blended. As the lower traverse of the Rahoenabsohnitts 11, a Bohlprofilstab 22 is seen, which engages in the L-profile of the vertical Rahoenstabes 20 and is welded to this. Correspondingly, a hollow profile rod 23 is provided as the lower cross member for the frame section 10, while the support flange 14 is supported on the upper horizontal longitudinal edge of the tube section 10 by a hollow profile rod 21. Overall, this results in a comparatively simple welded construction that can be produced with little effort.

Frame bars 20 pushed on. This completes the assembly of the Support frame to a dimensionally stable, fixed to the lower pallet locked assembly ended. Then the upper Pallet 16 put on. The loading of the pallets can be before or after assembling the support frame. As from Flg. 2 and> emerges, the assembled support frame is braced in the exemplary embodiment not directly on the floor surface or the supporting frame following downwards, but on the lower one Pallet itself from, over the lower horizontal frame bars 22 and 23. In practice there is a support surface for this these frame bars at the top of the pallet of only lower Width, approximately from 1 to 1.5 cm, proved to be sufficient «so that of the usable loading area of the pallet only a disappearing small fraction is lost.

The latticework or other construction of the frame sections can be made with steel, light metal or other metal profile bars. Construction elements also come from one suitable plastic into consideration. Instead of the sliding connections If necessary, joint, Locking or other non-releasable or releasable connecting elements occur. The adaptation of the construction of the carrier accordingly different pallet shapes is possible without difficulty.

The support frame according to the invention »in particular according to the embodiment shown construction, has among other things the following advantage

1) The usable pallet surface is made possible by the support frame

only decreased by an extremely small amount of about 4.5Ji while at the same time the external space requirement of the attached frame does not significantly exceed that of the pallet itself.

2) As a result of being over practically the geaaste height of the corner posts extending sight connections between the Raheen sections the entire supporting frame has a «high forest stiffness

and strength.

3) As a result of the lack of protruding inwards or outwards Structural parts, the risk of accidents and damage when handling the support frame is largely excluded.

4) The weight of a stack of pallets is over the support frame evenly distributed over the circumference of the lower pallets, causing deformation of the pallets that absorb this weight Lifting is avoided. .

5) The support frames can be easily operated by a single operator put together.

6) The rigidity of the support frame is achieved by assembling and stacking on top of one another, so that the entire support frame-pallet stack is comparatively rigid without difficulty forms to be handled unit.
