Abstract

The invention relates to a method for the production of a transport pallet (20), especially from recyclable paper wrappings, in addition to a transport pallet (20) per se. In order to produce the transport pallet (20) cheaply and to save weight, paper wrappings are preferably used in the construction of the transport pallet (20). According to the inventive method, the paper wrappings are cut into at least two lengths for longitudinal (2,3) and cross strip elements (1), said method also involving the cutting of said paper wrappings in a longitudinal direction. The longitudinal cut cuts the inner diameter of the paper wrappings so that, preferably, two identical paper wrapping segments are created. The remainders of the paper coverings are cut radially to a single length and are used as cleats (5). The cleats can be further processed and the longitudinal and cross-strip elements can be stuck thereto in a positive fit, whereby a light but extremely stable transport pallet (20) is produced.

Description

The invention relates to a transport pallet and a method of manufacturing a transport pallet, in particular as a recycling product, consisting of several tunnels and a stable support level and interconnected transverse and / or longitudinal cross members, at least some of the individual parts are made from recyclable paper tubes are.

Transport pallets are from today It is impossible to imagine everyday life without them, because they are freight forwarders, Trading companies etc. available stand and play a major role in the transport of goods. Because of their standardized dimensions these are picked up by, for example, pallet trucks or forklifts and be transferred. The materials to be transported here stacked on top, which consist of several in the longitudinal direction arranged boards exist and connected to each other by cross members are and rest on stud feet, which in turn have crossbeams for further stabilization.

Such wooden pallets are manufactured made of good grown wood and is therefore relatively expensive and time-consuming. It must also be taken into account that the Euro wooden pallets have a high weight and thus the transport capacity limit.

A transport pallet is known from US Pat. No. 5,067,418 known, which consists of horizontally arranged paper tubes with incisions, into the one that also runs horizontally and at right angles to the paper tubes sleeve sections are used. However, this transport range does not correspond to that Euronorm and can therefore not in the usual method using a forklift be transported.

WO 96/02427 is also a range version known with horizontally arranged pipe sections that are radial trained end faces have on the individual paper tube segments with a flat Side are glued on. For gluing the trusses and pipe sections however exclusively plane surfaces used, which on the one hand have only a small adhesive area and on the other hand, lateral shear forces have little resistance can oppose.

The invention is based on the object To demonstrate methods and a range of transport that can be produced inexpensively is a reduced weight with the same load-bearing capacity and has a high stiffness.

According to the invention, a method for manufacturing shown a transport range, which using recyclable paper tubes an inexpensive Manufacturing enables. The Process is characterized by cutting the paper sleeves to length a uniform lug length, the milling at least one continuous trough-shaped depression in the end face of the studs and the inclusion of a transverse and / or longitudinal cross member from recyclable paper tubes or Paper sleeve segments into the deepening of the tunnels. Existing paper sleeve remnants are of a uniform length cut to length as studs, so that even short paper tube remnants or sections can be used. So much for residual materials for example saw sections, sawdust or the like arise during production, these can using an adhesive, for example water glass binder, for replenishment the studs are used, so that a further increase in Load capacity and stud stability can be made. To connect the studs with the trusses the method further provides that the milling of a continuous trough-shaped depression and the milling a second half-sided trough-shaped depression arranged at right angles takes place, the recess on the outer radii of the original Paper sleeve diameter or of the paper tube segments are adjusted. The tunnels are preferably treated afterwards filling up the same, so that the operations are optimized. The trough-shaped depressions are preferably provided in the upper end face, whereas a rectangular one Groove in the of the trough-shaped Recess is milled diametrically opposite end face. The rectangular grooves serve to accommodate the narrow upper and lower paper tube segments and are preferably used as lower longitudinal beams. The upper trough-shaped Wells are used to hold the larger paper tube segments needed first being the shorter Crossbeams have a semicircular throat cut at their ends, which is also the original Paper sleeve diameter or the paper sleeve segments is adjusted. After using the crossbeams, if necessary Adhesive materials connected to the studs can be in a further operation, the upper longitudinal beams in the existing continuous troughs are inserted and also glued. The The tunnels are preferably arranged at equidistant intervals of the two longitudinal edges the transport pallet, so as with the well-known Euro wooden pallets Transport by forklift is ensured.

In a further embodiment of the method, the paper sleeves are cut to length to at least two lengths for longitudinal and transverse beams and cutting the paper tubes in the longitudinal direction for division into four paper tube segments, the longitudinal cut cutting the inside diameter of the paper tubes, so that preferably two identical paper tube segments are produced. After the necessary truss lengths have been produced, the paper tube is cut according to the invention by a frame saw with two knives in such a way that four paper tube segments are created. It is an identical paper segment on the left and right side as well as an upper and lower identical paper segment. There is also the possibility of changing the cut so that other sizes of paper segments are created if this is considered appropriate. However, the manufacture of two identical paper tube segments ensures that further work to be carried out can be carried out on the basis of a predetermined dimension. It is to be regarded as particularly advantageous that the paper cores which are present in large quantities as waste product, for example of carpet or paper rolls, are usually shredded with great effort and are recycled again. Due to the high inherent stability of the paper cores, however, they are excellently suited for the construction of a transport pallet after being cut as paper cores segments. The upper and lower paper tube segments can preferably be used as lower longitudinal cross members and the side paper tube segments preferably as upper longitudinal cross members. The shorter paper tubes or paper tube segments are used accordingly for the crossbeams. Due to their vault-like structure, the paper tube segments are characterized by their high stability and sufficient elasticity, so that on the one hand a light construction of the transport pallet is created and on the other hand there is sufficient load capacity. Due to the components of the same size, automatic production is furthermore advantageously possible, so that the production costs can be significantly reduced on the one hand by automatic production and on the other hand the necessary material is available inexpensively by recycling the paper sleeves. Furthermore, the transport pallets are characterized by the fact that, in the event of damage, etc., the entire transport pallet, as originally provided with the paper sleeves, can be recycled after shredding.

By merging and Gluing the studs, for example with a water glass binder, with the paper tube segments, being an upper planar Alignment of the cut surfaces of the paper tube segments takes place, becomes an extremely stable Configuration achieved in terms of load capacity is comparable to wooden pallets. Draws on the basis of the paper sleeve materials used the transport range according to the invention further characterized by the fact that there is a certain degree of self-elasticity is and thus the risk of damage to the transported Goods are being discounted. To store the goods is on the top cut surfaces of the paper tube segments or the tunnel a full-surface Pad positioned and glued so that even smaller goods or objects can be picked up can be.

The transport range according to the invention, in particular as a recycling product, consisting of several tunnels and a stable support level as well as interconnected cross and longitudinal beams, at least some of the individual parts are made from recyclable paper tubes, is further characterized by the fact that the studs are arranged vertically are and have at least one upper trough-shaped depression, in which the upper cross and / or longitudinal beams are included. However, all individual parts made of paper sleeve sections are preferred exist, so that a complete recovery of the large quantities paper tubes can be made. This applies, for example, to the studs to that from paper sleeve sections with at least one upper trough-shaped depression and one lower rectangular Recess are equipped. For necessary cross members the studs here two intersecting or one continuous or a half-sided trough-shaped Have recess in which on the one hand the cross members and on the other hand, the longitudinal trusses can be inserted and glued with studs. Are preferred here 6 studs used in equidistant Distances along of the two longitudinal edges are arranged. To increase the inherent stability the studs or the absorption of larger loads can the tunnels with sawdust, remains of pods or the like may be filled with an adhesive mixed. The paper tubes cut to the required dimensions will be by the method according to the invention sawn into two identical segment sections, whereby the course of the cut preferably cuts the inside diameter of the pipe. The narrower segment sections are in the corresponding rectangular recesses the studs inserted and glued, while the wider segment sections in the corresponding trough-shaped Deepening as cross or longitudinal beams used and glued.

The transport pallets according to the invention are characterized here by cost-effective production, in particular due to the use of existing waste materials, high stability and a light construction, the risk of injury also being reduced due to the relatively soft materials. A water glass binder is preferably used as the adhesive here, which sets quickly and has a high degree of residual elasticity, so that in connection with the ver used materials, the transport range has a great deal of elasticity. A major particular advantage is that if the pallet is damaged, it can be recycled if the transport pallet can be returned to the paper cycle after shredding. Due to a high demand for transport pallets and a large number of paper tubes, economical production in large quantities is also possible in terms of production technology.

Instead of paper sleeve sections there is also the possibility of tunnels from the paper sleeve remnants to make a pressed stud foot by mixing a binder, who has received the corresponding cut-outs, for admission the cross and longitudinal beams can be used.

The invention is further illustrated of the figures closer explained.
