Description

Large containers and process for their manufacture

The invention relates to a method for producing a device that can be automatically stacked on pallets Large container for a plurality of lightweight containers grouped together Goods such as paper handkerchiefs and paper kitchen towel rolls, whereby at least 2 rolls or Packets are combined into one container and at least 4 containers form a large container that in partial areas of a sheet-like sheet-like structure, in particular a plastic film is wrapped, wherein the web-shaped sheet of a material roll of a packing station fed into a u-shaped shaft, a predetermined number of containers in the U-shaped shaft introduced, the areas of the legs of the U-shaped legs protruding above the container Chute hit over the container and the

U-shaped shaft at the end faces by inserting swords to form a block bottom is folded and fastened; as well as the large container produced in this way.

There are currently large containers that contain a different number of packaged small containers contain, from a packaging, generally a film packaging, on all sides closed is. These large containers are stacked on a pallet, but have the disadvantage on that they have to be opened individually if the small containers in the department store with price tags or labels are to be provided. These large containers are cut open in the Sales area, whereby in many cases the small container is injured when it is cut open, the contents damaged and therefore unsaleable. Prefer bulk buyers such as department stores and supermarkets Hence a solution in which the small containers are in a tray that roughly matches the dimensions a pallet, with several of these trays, depending on the height of the pack in 4 to 8 layers are arranged on top of each other on a pallet and the last tray with one further covered as a lid. The stacking of the containers in these trays must be done by Made by hand and is therefore very time-consuming, and there is also an expense of bulky Trays, which is particularly annoying because the

Supermarkets in the sales rooms now these are generally made of cardboard or cardboard Trays accumulate in large quantities and have to be destroyed.

From DE-OS 31 23 212 multi-object packaging is known in which the individual objects between 2 foils are welded, whereby the upper foil interruptions, openings or incisions which are intended to take the place of each packaged item or certain objects that make up the contents of the multi-object packaging to be brought. According to this document, it is necessary to control the upper film so that there are always interruptions or openings are arranged above the packaged objects, so that these through the openings can be labeled and / or removed through the openings. This results in inevitably the consequence that a different top film for each packaged item must be used, so a top film that the size of the packaged item in terms of is adapted to their interruptions. Therefore, when packing different items for each article a separately adapted top film is required for this article, resulting in a leads to increased storage costs and continuous retooling work.

The present invention is therefore based on the object of creating a large container that consists of a commercially available material that does not have to be subjected to any special treatment, this large container enabling fully automatic pallet loading, only allowing safe handling on tape and roller transport routes, even if there is one has soft easily deformable content. Furthermore, the large container should offer the possibility of removing and labeling the small containers packaged therein without additional opening of the large container. Furthermore, the packaging material accumulating in the sales room should be reduced by using the large container and brought to a small volume.

These objects are achieved by a method for the production of a large container that can be automatically stacked on pallets for a plurality of lightweight goods, such as paper handkerchiefs and paper towel rolls, which are at least? Rolls or packets are combined to form a container and at least ¹ I container form a large container that is covered in partial areas by a sheet-like structure, in particular a plastic film, the sheet-like structure being fed from a roll of material to a packing station to a U-shaped shaft shaped

A predetermined number of containers are introduced into the U-shaped shaft, the areas of the legs of the U-shaped shaft protruding beyond the container are knocked over the container and the U-shaped shaft is folded in and fastened at the end faces by inserting swords into a block bottom, with the characterizing feature that the width of the roll of material is chosen so that after turning the legs they form an edge strip which extends in the area of the legs from the front face to the rear face of the large container and the thickness of a number of containers to a maximum 90 % covered.

A large container produced according to this process is open at the top, i.e. without additional Operations the application of price labels to the individual containers is possible. Through the The use of a sheet-like sheet-like structure to form the large container is no longer applicable up to now Common use of cardboard trays in which the individual containers were stacked, i.e. es the packaging material in the sales area is reduced by poorly deformable, large-volume units. Despite this surprising Advantages are the strength of the large container for safe handling on tape and Roller transport devices, so that even at different speeds and rotating

as well as sliding movements in the horizontal and / or vertical with the large container, as they are required for the automatic loading of pallets, no damage to the large container appear.

When using wrapping paper as a sheet-like sheet-like structure, the is fixed The block bottom is expedient by means of hot melts. According to a preferred embodiment of the invention however, a polyolefin is used as the material for the sheet-like structure, wherein the block bottom is fastened by welding the gussets. The path of the Material web made of polyolefin can be done so that the rear end face of the first Large container and the front face of the following large container formed at the same time , i.e. that a double seam or a wide-area seam is produced during welding and between the double seam or approximately in the middle of the wide seam is the separation of the first bulk container from the second takes place. Compared to the use of wrapping paper, where the The separation process has to be carried out with a knife, the separation of polyolefin materials is simplified, because a heating wire can act as a "hot knife" here.

The large container produced according to the method has the shape of a fruit crate, usually referred to as a tray, which consists of the thinnest wood, so in its edge area is provided with a wooden strip as a handle on each of the narrow sides. In the large container according to the invention, which can be addressed as a film tray, according to a preferred embodiment of the invention, the wooden strips are replaced by an edge strip with a strip width of 30 to 120 mm, which is connected to a web running on the end faces .

The web that occurs when cutting through the wide weld seam or the two parallel weld seams between the rear face of the first and the front face of the second large container is formed, the large container stiffens the foil tray because it is essentially Is arranged at right angles to the end face. In the case of large trays where the web length is 450 mm and However, there is more, especially when the tray is filled with soft, malleable goods, such as Paper towel kitchen rolls are filled, the risk of automatic transport on roller conveyors the middle area of the web bulges and gets caught on the guides of the roller conveyors. The resulting disruptions in the workflow can only be eliminated by hand.

A preferred embodiment of the invention therefore provides that between the two edge strips at least one reinforcement strip is arranged, this reinforcement strip expediently extends over the joint between the individual containers in the film tray. The reinforcement strips are advantageously welded to the web and have a width between 25 and 160 mm. It is essential in this context that the width of the reinforcement strips is chosen so that on one side the bulging of the web is reliably prevented, on the other hand, however, the packaged containers are still left free to such an extent that labeling is possible.

Further expedient refinements of the invention provide that the large container is made from a polyethylene film with a thickness between 50 and 100 μm, the height of the bulk container equal to or less than 400 mm, the width the same or less than 600 mm and the length is equal to or less than 800 mm. With the so designed Foil trays can be used to combine containers up to a maximum weight of 15 kg, whereby the lower economic limit at 2 kg, but preferably the limits between 4 kg and 10 kg and 2 kg correspond to 12 kitchen rolls. ·

The invention is explained below using the example of drawings:

FIG. 1 shows a large container with toilet paper sheets packed in layers and combined into individual containers,

FIG. 2 a foil tray with no content,

Figure 3 shows a large container that contains six containers of four rolls of kitchen towels,

FIG. 4 a film tray with reinforcement strips for kitchen rolls,

Figure 5 shows a large container with several reinforcement strips,

Figures 6A to G show the individual steps of the packaging process as basic sketches.

FIG. 1 shows a large container 19 which consists of six containers 5 and each container 5 contains twelve parcels of neatly folded toilet paper each of 140 sheets, as in French Market is usually sold. The container 5 represents the pack size that is removed by the end user from the bulk container 19 and the department store accordingly must be labeled.

In Figure 2, the same large container 19 is shown without the contents previously located therein, to give a better overview of this so-called foil tray. Like Figure 2 shows, it is a basket-like packaging, but made of very soft material exists, so that it is only self-supporting in the drawn form if it consists of relative strong foil or wrapping paper. Their shape is strongly dependent on the good that is in the Large container 19 is arranged, which can be seen very clearly from Figure 4, where this film tray Has rounded edges, which can be attributed to the introduction of containers 5 which four kitchen towel rolls 23 were combined to form a container 5.

FIG. 3 shows a large container 19, which consists of six containers ¹ J , each containing four kitchen towel rolls 23. The container 5 are therefore rounded on their narrow sides, which is why this rounding also occurs in the large container 19. Figure 3 differs from Figures 1 and 2 essentially in that no Vorstärkungsstreifen is present sixteenth This packaging strip 16 is only required if the web 18 has such a length that without this reinforcing strip 16 there is a bulge dos joint 18, which leads to

Obstructions on the transport route of the bulk container 19 leads. In Figure 6 is therefore a Large container 19 shown with five additionally arranged reinforcement strips 16, which each located above the joint 17 of the individual container 5, this form of packaging however, it is only used when large containers 19 have to be produced that are substantial Have dimensions so that there is a strong risk of the web 18 bulging. The production of the large container 19 is described in detail below with reference to FIGS. 6A to 6G.

A roll of material 2 arranged in a packing station 3 is used as a flat structure 1 80 .mu.m thick polyethylene film is peeled off and passed over the table 22 of the packing station 3. The feed belt 21 is arranged perpendicular to the table 22, on which four of them form a container 5 summarized kitchen towel rolls 23 are transported and pushed onto the table 22. That Sheet 1 moves on as soon as the required number of containers 5 on the Flat structures 1 are available, in the present case six containers 5 are combined.

The F3äehengflhiIde 1 is in π (M πftη Rnndboreίchon erected during the feed cycle (Fig. 6B) and thereby forms a U-shaped shaft 4, the legs 6 of which extend over the height of the container 5

protrude. This U-shaped shaft 4 is guided between guide plates 24, its legs 6 are over the edge area of the container 5 folded (Fig. 6C) and form the edge strips 12. The containers 5 are thus in an open Hose, which was formed from the sheet-like structure 1, wrapped in.

A narrow web of material 7 is guided onto the thus wrapped container 5 (FIG. 6D) that it covers the joints 17 between two containers 5. By a roller, not shown the material web 7 is pressed onto the container 5 and held in this position. A The slide 20 pushes the rows 14 of arranged between the guide plates 24 from behind Containers 5, while swords 9 from both sides into the U-shaped shaft 4 Press in from the sheet-like structure 1 and fold the gusset 15.

In the retracted state (Fig. 6E) of the swords 9 and under pressure of the container 5 through the Slide 20, two sealing jaws 25 move from below and above towards one another and meet in the middle of the height of the container 5, whereby from the U-shaped shaft 4 at the end face 8 a Block bottom 10 is formed. The heating wire 26 is arranged between the sealing jaws .25, after opening the sealing jaws 25 between

the two weld seams 27, the polyethylene film from which the sheet 1 is made, severed.

With this welding process, the rear face 8 of the first large container 19 and at the same time the front face 8 of the second large container 19 is formed (FIG. 6F).

The resulting large container (FIG. 6G) is shown in FIG. 3. The one pressed onto the container 5 The web of material 7 is welded to the web 18 formed during the welding process and forms the reinforcement strip 16, instead of a reinforcement strip 16, if very narrow containers 5 are combined to form a large container 19, several reinforcement strips 16 are arranged side by side, the however, they are all guided in such a way that they each cover the imperfections 17 between two containers 5 and leave enough space on the containers 5 for the attachment of price labels.

The thickness 13 of the container 5 depends on its content and the arrangement of the contents in the container 5. It is also decisive for the width of the marginal strip 1? and the width of the reinforcement strip 16. The width 11 of the material roll 2 is chosen so that the edge strip 12 the container 5 is half covered.
