DE3810089A1 - Non-combustible stack pallet and process for its manufacture - Google Patents

Abstract

To form an inexpensive non-combustible stack pallet, it is proposed to use for this purpose essentially a fibre mass of artificial mineral fibres, such as rock fibres or glass fibres, pre-impregnated with resin, which mass is compacted by a pressing step and hardening of the binder to an apparent density of 100 to 500 kg/m<3>, preferably 300 kg/cm<3>, the binder content being less than 10 % by weight, preferably less than 6 % by weight. For a further possible increase in the strength of the stack pallet, inorganic fillers and/or inorganic mouldings and also two-dimensional reinforcements, which can be introduced into the fibre mass, can be provided.

Description

The invention relates to a stack pallet for storage and Transport of piece goods and one for their manufacture particularly suitable process.

As is well known, pallets are used as load handling devices for bil large cargo units consisting of several single units loads or general cargo. For this purpose, pallets or stacking pa Latvians with the standardized dimensions of 800 mm × 1200 mm or 1200 mm × 1600 mm and a load capacity of 10 kN ver turns. The pallets are designed such that they run under, lifted and transported by industrial trucks can be.  

Usually pallets or stacking pallets are made today Made of wood. There are also art palettes fabric reinforced with waste from textile glass fibers. In addition to metal pallets, which are relatively expensive, they have Pallets shown at the outset have the major disadvantage that they are flammable. This flaw is an additional factor drive in fires in large camps as they are stacked in the Goods were multiple layers of highly flammable material the one in which the combustion air enters unhindered can penetrate, while practically not to the fire water are common. They then spread a fire all over the place Storage area and lead to the collapse of the material stack. Fer There is also a particularly great risk of empty stacks Wooden pallets.

This deficiency can first be overcome by using Me encounter tall stack pallets, even if they are at first equipment are considerably more expensive than wooden pallets. This However, disadvantage can be wholly or partly due to a longer one Period of use and lower insurance premiums be made up for again. However, there is a problem if these pallets cover the area of the respective mold store or their external storage in the direction of customers or consumption leave places. Then with a partial loss Expect expensive metal pallets, or you have such an expensive one Introduce deposit system, which is mostly in no reasonable Relationship to the stacked goods and therefore the customers annoyed, apart from the annoying repatriation of the pa Latvians.

The present invention seeks to remedy this. your the task is based on such a stack pallet beat that is on the one hand non-flammable and on the other hand from Seen here z. B. compared to a flammable wooden pallet te is still economical.  

This object is achieved in that the stack pallet consists essentially of a bound fiber mass with a bulk density of 100 to 500 kg / m ³ , preferably 300 kg / m ³ , which is incombustible due to its composition. The fiber mass can consist of bound mineral fiber plates or felts with a binder content of less than 10% by weight, preferably less than 6% by weight (e.g. phenolic resin).

For explanation it should be noted here that under the term "Mineral fibers" artificial mineral fibers (KMF, such as glass wool, Rock wool and cottage wool) can be understood. Furthermore, with the term "non-flammable" means a classification such as that used for KMF products usually come with a so-called non-flammability certificate is. Finally, at the weight percent specified, the following any inorganic fillers and / or specified disregarded inorganic moldings.

The mineral fiber stacking pallet according to the invention can be used in their execution vary. In its simplest form them out of a normal stiff felt or a plate into which an industrial truck with its forklift forks simply off the Pushes in and so picks up the pallet and trans ported. A preferred embodiment, however, is that the Stacking pallet cavities for receiving the forks from the hallway has conveyors on the underside in the manner of a cross are milled or molded or stamped. Furthermore, it may be advantageous that in places of higher pressure load as with the stacking of drums, machine parts and the like. additional inorganic fillers and / or inorganic Shaped body molded into the fiber mass of the stack pallet are. It is possible that the stack pallet over their distributed over the entire area or only in places of an elevated Pressure absorption granules such as gravel, foam concrete, pumice or Like., Has. With regard to the molded body is foam glass, porous clay, hollow blocks, sheet metal or the like. ge thought.  

Another improvement on a stacking palette in terms of their strength can be advantageously achieved that they are on or in the vicinity of their top and / or Un The bottom is armored like with metal foils, flame retardant ren plastic films or papers, with glass fiber fleeces, Ma wire, expanded material or the like. It is also advantageous possible that their bulk of fibers are essentially parallel Mineral fiber lamellae exist, the fiber levels of which are essentially Chen perpendicular to the surface of the stacking plate fen.

It is also possible that the fiber mat of a stacking pallet binder injected into it, such as cement or gypsum stillage, contains. This not only increases their firmness speed, but also the possible binder content without thereby the incombustibility is lost.

Finally, it is also possible to make a stack pallet from here conventional mineral fiber boards, such as ceiling cladding and Assemble acoustic panels, as well as the fiber mass lath-shaped strips from conventional mineral fiber product to arm.

A particularly suitable method for producing a he inventive stacking pallet is that the fiber mass from those that have not yet hardened binder Mineral fibers, such as stone or glass fibers, are formed in layers as felt - possibly with the inclusion of the aforementioned Reinforcements - compression compaction with hardening be subjected to the binder at elevated temperature. Here, the cavities for receiving the forks from Industrial trucks during the compression process by corre sponding Cores are molded or embossed. In the end the mineral fiber layers can have different properties shafts, in particular different density and / or un have different fiber lengths.
