Description

25th

The invention relates to a device for packaging goods stacked in packages, in particular bricks, in shrink film, the packaging consisting of a lower film, which from below is folded up, and an upper film, which is put over the finished package, consists of un individual bars arranged at a distance from one another and with support on four sides of the Folding devices arranged to be movable upwards to be packaged. A device of this type is through US Pat. No. 2,858,657 has already become known.

This known device has rods which can be displaced in the vertical direction and to which four angular elements are articulated. These elements can be connected to one another via a flat plate in such a way that they act as a single folding element. The incel-shaped elements. ¹ e are doing gfeuern under the influence of Z ", which soon subside on its voltage and thus make the operation troublesome.

Quite apart from that, this known device is exclusively for driving in cuboid and cube-shaped packaging goods without protruding edges.

U.S. Patent 3,222,844 is concerned with a method or apparatus for packaging of continuously moving products with a film. A plate is provided, over which the packaged goods slide. In the area of this plate are two cranked plates, which are in the Form channels with the end edges of the plate in the area of the crank. These channels can be accessed through a Suction channel can be connected to a vacuum source. According to a particular embodiment of this (Known devices are pipes with nozzle openings provided through which compressed air exits. Piese compressed air hits the side edges of the | B> he put the packaged film and lays it #ese under the aforementioned plate.

The German Offenlegungsschrift 1 149 047 shows ♦ packaging of goods stacked in packages, ! Whereby this packaging consists of a lower and upper film and the lower film is wrapped in the package will.

The object of the invention is to show a device with which the packaging of stacked Goods, especially bricks, in shrink film is largely possible automatically.

This object is achieved according to the invention in that each folding device consists of a bracket formed tube, whose horizontal part rmt distributed over its length, on the packaged goods pointing holes is provided, wherein the Bübersfan an air supply line, which is an actuating lever is assigned, are connected, and that horizontally movably arranged bracket for pressing the upper film are provided on the lower film.

The device according to the invention is limited to a minimum of elements; it consists in Basically just eight brackets that are bent from simple tubes. Let these temples produce in an extremely simple manner; in addition, they are not subject to any wear and tear and are otherwise not exposed to any operational disruptions.

Another advantage of the device according to the invention is the saving of labor. Pallets can also be dispensed with, resulting in savings in material and labor costs for the production of these pallets. These advantages have a favorable effect on the price of the bricks the end.

An exemplary embodiment of the invention is explained in more detail below with reference to the description. It shows

F i g. 1 shows a view of the device, with the package already created and the lower film in the package is wrapped in and the upper film is pressed against the lower film for welding,

F 'g. 2 and 3 each show a partial view of the device in different operating positions while the lower film is being inserted.

1 with a support is referred to, which consists of individual, spaced rods consists.

On this support 1 is a lower film 2, on which a layer 3, namely a so-called foot layer, made of bricks.

There are also provided on the four sides of the goods to be packaged so that they can be lifted. Each folding device consists of a tube designed as a bracket 4, the horizontal part <Xa of which is provided with holes 5 which are distributed over its length and point towards the goods to be packaged.

The bracket 4 is connected to an air line, which is not shown in the drawing Operating lever is assigned.

When the bracket 4 has reached the upper position, the holes 5 are at the level of the upper one Edge 3a of the brick layer 3. By pressing the operating lever, not shown, the air Binding through the bracket 4 and exits through the holes 5, so that this air on the pulled up Lower film 2 hits, blows this and deposits it on the brick layer 3, so that this of all four Sides with the lower film 2 is wrapped (Fig. 2 and 3).

The rest of the several-

Ren brick layers existing package 6 deposited so that the lower film 2 between the brick layer 3 and the lower brick layer 7 of the package 6 is located.

By covering an upper film 8 over the entire package, a complete package is created from all of them Sides wrapped in shrink wrap.

The hanging upper film 8 is then by means of horizontally movable brackets 9, which are also consist of tubes and are bent rectangular, pressed against the lower film 2, so that Oberfo-He 8 and the lower film 2 in the area of the brick layer 3 by welding during the shrinking process connect (Fig. 1).
