Description

Method for packaging building blocks The invention relates to a Method for packing building blocks and similar bodies in a package.

To rationalize the transport of building blocks from the manufacturer to the point of use and for individual transport on the construction site become, building blocks or the like no longer to be transported loosely and at the place of use to be dumped, but to be combined in packages that are such as B. forklifts, loaded onto trucks and then at the point of use be unloaded using a crane and special grabs. Disadvantage of this process is the additional work involved in packing the building blocks in the manufacturing plant arises. This requires packaging material and a certain amount of work.

Pallets made of wood are generally used as packaging material placed under the stone packages and holding material such as wire, steel strips, plastic film or similar.

Especially the pallet underneath because of the load resting on it must be stable, it represents a considerable 'vert.

For this reason, the pallets must be returned to the manufacturer and be secured in the meantime with a J, eih, fee. Besides that they wear out and have to be thrown away after a few transports. the Additionally required steel strips or wires cause additional costs and put on the Construction site is a source of danger. These processes arise, especially at Mass building materials, such as B. Building blocks - which in themselves do not represent a great individual value -, considerable additional costs.

The invention is based on the object, especially the large ones Eliminate loss of packaging material as much as possible and the packaging process to simplify.

To achieve the object, a method is used which is described below is described with reference to the drawings: Figure 1 shows the side view of a stone stack, consisting of a lower base layer 1, which consists of the same stone material, like the stones to be packed and a film placed underneath it is expediently shrink film.

In a first operation, the film 2 is shown in FIG. 2 at two edges folded around the base layer 1. In the next step, the Stone stack 3, which has a greater width than the base layer l, on this after Fig. 2 prepared base layer 1 placed and with a hood pulled over 4 made of shrink film, which is so long that its edges down over the stone pile are sufficient.

Then according to Fig. 4 by means of a clamping device 5 of the protruding Part of the hood 4 is pressed against the film 2, which encloses the supporting layer. In Fig. 5 shows the other side view from which it can be seen that the base layer 1 z. B. consists of two stones or slabs, the full width of the rest Stack corresponds.

During the shrinking process, the film 4, which is attached to the film 2, according to FIG. 4 and FIG. 5, in the area zone 6 a stream of hot air is heated and pressed against the film 2 that it is with this welded.

Fig. 6 shows another possible arrangement of a stone package, consisting from a base layer 1, from vertically arranged plates and a stone package made of horizontally arranged panels.

Fig. 7 shows a further possible arrangement of a stone package, consisting of large-format blocks 3, which are on a base layer 1, which are also consist of large-sized blocks that are arranged so that both lateral Airfoils 7, like a central cavity 8, are formed. The wings 7 and the cavity 8 are required to hold the stone package at this point by means of gripping devices, such as B. a fork to be able to accommodate.

It has been shown that it is possible to use this method1 usual size of z. B. 100 x 100 x 125 cm multiple loading and unloading and over To be able to transport long distances without the piles opening or the content is damaged. Advantageously, a thicker one is used for the lower film 2 Material used as for slide 4.

The thicknesses for the foils can be, for. n.

for the lower foil 2 0.175 mm for the upper foil 4 0.150 mm. It is also possible to use foils in which to reinforce the strength Threads or nets are incorporated.

When using this method, there is a particular advantage that there are no losses for a pallet and that that used as a base layer Stone material has the same dimensions as the material in the stone pile.

Claims (7)

PATENT CLAIMS Method for packaging building blocks by means of a shrink film cover, characterized in that the stones to be packaged (3) from a lower layer (t) made of the same material as the stones to be packaged and which can be used as a building material which is arranged to have a or several support surfaces <7.8) for transport equipment under the items to be packed Keeps stones free and holds them to the stones to be packaged by foil alone will. 2. The method according to claim 1, characterized in that the lower Layer (i) is wrapped in a film (2) in a first step, with the edge of the film still on top of the lower layer so that when the actual stone package is placed, the edge of the film is pinched. 3. The method according to claim 1 and 2, characterized in that the the film used to wrap the lower layer is thicker than that used for the to packing stone material used foil. 4. The method according to claim 1-3, characterized in that the Foil (4) for the stones to be packaged has a thickness of preferably 0.1 to 0.2 mm and the film (2) for the lower layer has a thickness of preferably 0.15 to 0.25 mm. 5. The method according to claim 1 - 4 dadm7eln characterized in that the Upper film of the item to be packaged before welding with the lower film is pressed against it by the gripper (5). 6. The method according to claim 1-5, characterized in that the pressing the upper film (4) supported on the lower film (2) by a stream of hot air which at the same time leads to a welding of the two upper surfaces. 7. The method according to claim 1 - 6 gekennçeichnet that a Foil is used, which is reinforced by means of incorporated threads or nets.
