j| Device for preventing the contamination of trans·

port ¹ branches on pallet..

The invention relates to a device for preventing the slipping of transport boxes stacked on pallets, the pallet surface having depressions or gaps.

For transport, a large number of transport boxes are placed on a pallet, as the handling of such stacks of transport boxes placed on pallets is made considerably easier by mechanical lifting and transport equipment, such as forklifts. Particularly when the transport boxes are made of plastic, there is a risk that such stacks of transport boxes on the pallets will shift during transport if there are jerky driving movements, heavy braking of the vehicle and severe inclinations, as is possible on ships in a storm or during rail transport when stopping on a banked curve.

In order to counteract this danger, pallets are made of plastic, which have a rim around the edge that encompasses the transport box bases. It has also become known to provide pallets made of plastic with projections or depressions on their surface in order to hold transport loads in the form of flower pots, ^buckets and the like on the pallet during transport.

Manufacturing pallets with standard dimensions of 1000 mm x 1200 mm and pallets of similar size from plastic involves a lot of effort, high costs and also difficulties. For this reason, such pallets are difficult to establish on the market. The pallets mainly used are made from wood, which consist of two layers of boards arranged at a distance from one another, between which square pieces of wood are arranged transversely. The gaps between the boards forming the pallet surface and the surface roughness of these boards are not sufficient to guarantee stable stacking of transport boxes made of plastic, and it often happens that plastic transport boxes slip on such pallets. Such slipping does not always have to lead to the stack falling over, making unloading the transport vehicle more difficult. A transport box load that has slipped can no longer be safely unloaded from the transport vehicle using mechanical unloading equipment, so that the transport boxes must be removed from the transport vehicle individually by hand.

For pallets made of plastic it is known

In order to avoid the disadvantages of the prior art, it is the object of the invention to provide a method for detecting, in a simple manner and with little ^effort , the speed of the arrows in its ^direction of ^travel .

The invention consists in the fact that between the godet and the transport boxes stacked on it ^there is a plate provided with projections which engage in the depressions or indentations of the pallet surface and which is provided with further projections which rest on edges or ribs of the transport box base or engage in depressions in the transport box base, or which is provided with recesses which engage with their edges on edges , ribs or indentations of the transport box base. - : -. &eegr; .

By inserting these projections between the pallet and the stack of transport boxes , the projections, which on the one hand engage with the surface of the pallet and on the other hand interact with the transport boxes, ensure that your stack of transport boxes

<)]■■■<;&igr;-Platt--.' can not only be used as a cover for a regular stack of transport boxes, it can also serve as a lid for a stack of transport boxes which is picked up on the stack of boxes on the pallet, &pgr; l 11 c &igr; transport boxes are a uniformly shaped &Ggr;&igr;-Jt with downward-facing edge projections as a common lid for all transport boxes which is placed ^on the topmost stack layer.

^The special lid also acts as a safeguard against slipping of the additional pallet placed on a stack containing another stack of transport boxes when multiple pallets are to be placed on top ^of one another. In this way, a large number of stacks, the weight of which would exceed the capacity of a forklift truck, can be arranged on top of one another in a slip-proof manner if another pallet ^containing another stack of transport boxes is placed on the plate serving as the lid.

This plate can be manufactured from plastic with considerably less effort than is possible with ^D a 1 e 11 e &eegr;. The stability requirements are also considerably lower than with plastic pallets.

This plate can be produced in three different shapes:

One embodiment is characterized by a

The device serving as a stacking aid is characterized by a plate which is provided with projections on both sides and is to be placed on the pallet, which has projections which are arranged at a distance from two or more depressions or gaps and whose dimensions are smaller than the depressions c of the gaps in the pallet surface, and whose surface facing away from the pallet has projections whose arrangement and size is such that they rest on the bottom of the transport boxes or on projections or depressions located on the bottom of the transport boxes.

It may be useful if this plate is on ^H er

the side facing away from the pallet has projections on its edge, which preferably form a peripheral edge which encompasses the entire bottom of the lower layer of the stack of transport boxes. This edge does not need to be high, it is sufficient if it is up to 50 mm high.

It is useful if the cross-sectional dimensions of the projections facing the pallet are trapezoidal. This has the advantage when manufacturing this plastic plate that serves as a stacking aid that it is easy to demold and when using this plate that serves as a stacking aid, it has the advantage that the plate easily slides into the gaps or recesses of the pallet and the plate that serves as a stacking aid falls into the correct position, and on the other hand it also means that the transport costs can easily be guided into their exact position.

It can be advantageous if the projections on the side facing away from the pallet have the shape of angles, squares, rectangles or a Θ shape. This gives the projections a high level of stability, while at the same time allowing them to be adapted to the various base designs of the plastic transport containers.

It is also advisable if the projections that engage in the coils of the pallet surface have a height that is less than half the pallet thickness. This ensures that the <■> panels can also be used as a cover or intermediate ceiling for the

Stacks of transport boxes can be used when additional pallets with stacks of transport boxes are stacked on top of each other.

The essence of the invention is explained in more detail below with reference to an embodiment shown schematically in the drawing . They show:

The plate 2, which serves as a stacking aid, is placed on the pallet I, on which the transport boxes 3 are placed. The pallet 1 consists of an upper

and a lower layer of boards 5 nailed to square timbers 4 at a distance from one another. The transport boxes 3 have projections 6 on their underside, which are designed as web or rib formations in order to give the boxes placed crosswise the necessary support in the stack. These projections 6 each dip into the transport boxes stacked underneath.

The stacking aid 2 consists of a flat plate f 7, which has projections 3 at the top, which

! In the embodiment of Fig. 3, the projections 9 protrude upwards; they are located on the side of the plate 7 facing away from the ;;- ^: pallet 1.

In the embodiment of Fig. 4, the projections 9 are directed downwards, they are attached to the side of the plate 7 that faces the pallet 1. The projections 9 are not as deep as the projections 8. Between the projections 9, recesses 11 are formed in which feet of differently shaped transport costs 3 stand.

In the embodiment shown in Fig. 5, the plate 7 of the stacking aid 2 has recesses 13 which are in the form of holes into which the projections 6 on the bottom of the transport boxes 3 fit. Here, the transport boxes 3 with their bottom projections 6 stand directly on the bottom 5 of the pallet 1 and are held against sideways slipping by the edges of the recesses 13 of the plate 7 of the stacking aid 2.
