DE2425401A1 - Stackable bottle crate plastic pallet - has peripheral edge extending upwards to fit insteps in crate bases - Google Patents

Abstract

The pallet is for use with bottle crates stepped inwards at the bottom for stacking, and has a built-up grating-type supporting surface joined by supporting profile sections to three parallel skids. The supporting surface has a peripheral edge extending upwards, whose height is such as to fit in the stepped portions of the crates on it. The profile sections are open at the top and bottom, and comprise vertical walls running at right angles to the skids. The skids can be of trapezium section, with alternate recesses in the top and bottom, and in their lengthwise direction the supporting surface can be slightly inclined from the outside to the middle.

Description

"Plastic pallet for stackable bottle transport crates" The invention relates to a plastic pallet for stackable bottle transport boxes with a lower inwardly drawn stacking edge with the grid-like support surface is connected to three parallel runners via support profiles.

Numerous suggestions have already been made, the well-known transportation and To design storage pallets made of wood also made of plastic. Aimed for are plastic injection molded constructions in one-piece design that meet the high Load-bearing requirements and match the stability. So far it has always been assumed that such a range of four sides should be able to be driven under by the forks of a pallet truck or forklift.

The construction of a plastic pallet (DT-OS 2 148 291), with three parallel runners formed at the bottom using the injection molding process Shaped or demolded by sideshifter in a plane parallel to the support plates will. The runners are to increase the stability by webs on their underside additionally connected to each other, there are entry openings for the runners between the runners Formed forks of a forklift. Such a construction requires a very complicated one Injection molding tool with numerous slides that move inside the tool Need to become.

In the case of pallets on which fixed transport units, especially boxes, are set up, it is important that a possible for the support surface low material expenditure is necessary. There are therefore already proposed pallets, whose support surface is constructed like a grid. The demolding of this lattice-like However, construction is only possible if the slides for forming cannot be moved across or demolding of other pallet parts are necessary.

The invention assumes that in most cases it is not necessary is that a palette from all four sides can be driven under. As a rule, the pallet parked by a pallet truck or forklift truck is used for Onward transport again in the same direction. It therefore appears in these cases sufficient if a pallet from two opposite sides can be driven under.

The object of the invention is to provide a one-piece plastic pallet for stackable bottle transport boxes with a lower, inwardly drawn stacking edge to propose4 which are produced in a simple manner using the plastic injection molding process and can withstand the high weight loads. The well-known bottle transport boxes With their stacking edge pulled inwards at the bottom, they can each be placed in one below Insert the arranged box. The plastic pallet according to the invention must comply with this principle be adjusted.

To solve the problem of the invention, a plastic pallet is the initially mentioned type proposed, which is characterized by a-umlaenden pulled up Edge on the support surface, the indentation of the lower stacking edge of the erected Bottle transport boxes are adjusted in height and continue to be marked is made up of walls that are perpendicular to the support surface and open at the top and bottom Support profiles running across the runners0 According to a preferred embodiment According to the invention, the runners, which are trapezoidal in cross section, should alternate have recesses on their top and bottom.

About unavoidable deflections when lifting the loaded plastic pallet to counteract, it is also proposed that the support surface in the longitudinal direction of the runners slightly inclined from the outside towards the center.

Such a pallet according to the invention is in a simple manner with two To produce tool halves that can be moved perpendicular to the support surface. Sideshifts are only necessary for shaping or demolding the runners, which be moved in one direction.

Such a pallet requires a relatively small amount of material with high stability. The support profiles that cross-connect the runners give the pallet a high flexural rigidity in the main directions of loading, which are different when lifting of the loaded pallets by the pallet truck. With these pallet trucks are the Forks close together. This results in a relatively high bending load the boxes set up in the edge areas of the pallet.

The invention is based on an illustrated embodiment explained below.

It shows: FIG. 1 a partial plan view of a pallet, FIG. 2 a Partial bottom view of this palette, Figure 3 shows a section according to Line I - I through a pallet according to FIG. 1, FIG. 4 a section along the line II - II through FIG. 1, FIG. 5 the top view of a runner, FIG. 6 a section through the runner according to the line III - III and FIG. 7 a sectional view in the edge area a pallet with an attached bottle transport box.

The support surface 1 of the plastic transport pallet is grid-like constructed from webs 12 crossing each other at right angles. For non-slip securing of the A peripheral edge 11 is formed on the outside. The height of this edge 11 corresponds to the height of the indentation 53 on one of the in Bottle transport boxes 5 shown in FIG. 3, which have the inwardly drawn stacking edge 51 own.

Three parallel runners 4 are with the support surface 1 over the support profiles 2 and 3 extending transversely to the runners 4 are connected. The outer Walls 21 of the two outer support profiles 2 are through the side wall of the pallet educated. This wall 21 continues upward into the circumferential edge 11. In particular from Figure 3 it can be seen that these support profiles 2 and 3 each only for Support surface 1 vertical walls 22 b. 32 are formed. The one with it The resulting chambers are open at the top and at the bottom while the forks are retracted with the rollers of a pallet truck hinged at the bottom into the pallet between the support profiles 2 and 3, the runners 4 are conical in cross-section. the end Reasons to save material are alternately on these runners Ausne @ aungen 41, 43 are provided on the top and underside thereof. In addition, you can still Recesses 44 are formed on the underside of the runners. At the top of the runners are each formed between the recesses 41 inclined drive-on surfaces 42.

FIG. 3 shows in principle how the bottle transport boxes 5 can be set up in the edge area of the pallet. These bottle transport boxes with an upper edge 52 have the inwardly retracted stacking edge 51 at the bottom Entry point is denoted by 53. From this figure it can be seen that with Bottle transport boxes filled pallets can be stacked on top of each other. It is advantageous that the support profiles 2 with their relatively wide lower The support surfaces rest on the edge of the bottle transport boxes.

In Figure 7 it is shown in a somewhat larger representation that the Support surface 1 is inclined from the outside @ ur center. The inclination is with H denotes. It is advisable to keep angles of inclination around 10 in size.

Due to this inclination, the transport boxes that have been set up become insignificant inwardly inclined towards each other. The load takes place approximately in the middle through the forks of the pallet truck, this inclination will possibly result in a Deflection compensated for again.

Because bottle transport crates often sloped outwards on the top If you have flank strips, it may be useful to place one on the underside of the pallet Provide edge 23, as indicated in Figure 7, which is also slightly when stacking several pallets with bottle crates one above the other, this edge of the range of edge strips of the lower boxes fits at. When stacking empty pallets, this edge centers and contributes to the formation a solid stack.

As can be seen from the figures, it is with such a pallet possible to put the dividing plane at any height, in this dividing plane in certain areas the necessary cross-sections of the supporting surface Bridges can be realized so you have the option of using suitable Profiling and design of the webs make the pallet sufficiently stable and torsion-resistant to design,
