Abstract

Transport pallet. This comprises 2 rigidly connected, deep-drawn plates of polyethylene, with reinforcing ribs and with a slip- and wear-proof doubling layer, pref. of ethylene/vinyl acetate copolymer and/or a polyisobutylene-poly-ethylene mixture. The ribs on the upper and lower plates are differently shaped. The lower plate has openings for the wheels of the stacker truck. The ribs are aligned with the pallet supports. The pallets do not crack and easily cleaned making them suitable for use in food factories.

Description

Transport pallet The invention relates to a transport pallet two firmly connected and provided with reinforcing ribs by deep drawing Plastic panels.

Transport pallets of this type are known, they are used for transport of bottle crates and similar piece goods that are loaded and transported in stacks are roller blind These transport pallets should be k sides according to the standard be accessible by forklift truck and from two sides by pallet truck can be lifted and transported.

The previous transport pallets consist of wood, metal and plastic or from different materials. Polyethylene sheets are particularly suitable manufactured pallets, since they are relatively economical to manufacture.

They are also shatterproof. These pallets can also be hygienic Meet the requirements of the food industry, as a frequent and thorough Cleaning is easy to do.

The object of the invention is to achieve the usual minimum load capacity of approx.

with sizes of 1000 x 1200 mm and with a wall thickness of 3 - 5 mm to be able to record. Furthermore, the general cargo and others to be transported Objects such as bottle crates do not slide on these plates. This requirement cannot be met by a roughened surface of the polyethylene fulfill.

To solve this task it is provided according to the invention that the The range outlined at the beginning has the following characteristics in combination: n) The panels, made of polyethylene, have a non-slip and abrasion-resistant finish Doubling layer provided.

b) The lower and upper plates have different stiffening ribs Design on.

c) The lower plate has openings for the support wheels of the stacking vehicles Mistake.

d) The stiffening ribs of the panels are on the pallet supports aligned.

A transport pallet constructed in this way can be used in the deep-drawing process relatively easy to manufacture. Used for the doubling layer of ethylene vinyl acetate copolymer and / or a Polyi sobutyl en-Polyäthylengemi s ch is used, so the slip resistance particularly taken into account. The doubling layer has approximately one thickness of 1.5 mm. It is applied at a temperature of 80-100 °. In the copolymer of the ethylene vinyl acetate, the ethylene component predominates.

To the necessary minimum load-bearing capacity of the pallet despite the lower To be able to achieve wall thickness, the design of the ribs is also special To make demands.

It is useful that according to the invention on the pallet supports aligned stiffening ribs formed as ring ribs running in a rectangle are and in the enclosed middle part concentric circular ribs with ray-like Rib processes are arranged.

The connection of the upper and lower plate can be done by deep-drawn Plate areas are made possible. But it is also conceivable to attach the plates to the provided places with corresponding cylindrical bodies made of plastic associate. This can be done by welding or riveting. To the bending stiffness To promote at the edges, the inner sides of the plate can be provided with additional the rib design adapted plates are covered. This becomes the uttered The platemark largely rounded off.

Further details are described in Figures, for example.

Fig. 1 shows a pallet according to the invention in plan view, the upper plate part is partially removed.

Fig. 2 and 3 show two possibilities, the top and bottom plate to connect with each other0 Fig. 4 shows a cross-section through one of the plates.

In sub. 1 is the bottom plate 1 at nine points with the top plate tied together. The plate 1 shows ribs 2 designed in the deep-drawing process, each of which run parallel to the 4 openings 3. These openings serve that the Can support Palettenhublfagen with its edges on the floor.

The top plate 4 shows next to the outer stiffening rib 5 a annular stiffening rib 6. This is between 4 support points 7,8,9 and 1o arranged. The middle area shows two concentrated ribs 11 and 12, wherein the outer annular rib carries several extensions 13. These lead to a significant Stiffening and thus increase the load-bearing capacity of the Palette.

In Fig. 2 particularly deep-drawn parts 14 and 15 are together welded, they are used to connect the top and bottom plates.

In Fig. 3 the top and bottom plates are by means of a cylindrical body t6 and a rivet 17 connected. The cylinder 16 can, for example, made of reinforced Consist of polyester resin.

Fig. 4 shows part of a cross section of the polyethylene sheet 18, from which the pallet is made. The plate bears a doubling layer 19. The The plate is 3.5 mm thick. The load-bearing capacity of the pallet is Size of about 1 square meter at least looo kg and in the stack at least 3000 kg.
