"PROCESS FOR PALLETIZING TEXTILE PACKAGES"

FIELD OF APPLICATION

The present invention relates to a process for palletizing textile packages.

More specifically, the invention relates to a method which provides for the positioning on pallets of the textile packages after bagging them, as well as subsequent finishing operations of the pallets thus loaded.

The term "textile packages" generally refers to any type of yarn or ribbon package usually wound in cylindrical or truncated cone shapes, which can also refer to materials consisting of continuous fibers, such as synthetic fibers, or discontinuous fibers, such as for example the fibers of cotton, wool, etc.

TECHNIQUE NOTE

A plurality of procedures and devices suitable for palletizing packages produced in textile machines, particularly automatic winding machines and open-end spinning machines, are known in the state of the art.

Said packages are advantageously of the truncated cone type, to which particular reference will be made in the following description.

These bobbins are picked up by said textile machines manually by means of suitable devices, such as robots, manipulators or specific palletizing devices, which have the task of arranging them neatly on the relative pallets.

The bobbins are positioned on superimposed layers, which are separated from each other by the known perforated cardboard boxes.

Palletizing operations can be carried out manually but also completely automatically, today being able to have fully automated devices specifically set up.

In the execution of each layer of cones, these are suitably spaced apart from each other to avoid damage to the yarn or confusion of turns thereof.

This spacing between cone and cone must be maintained over the time that the cones are locked in their position by means of the cartons interposed between layer and layer.

For this purpose, said cartons have holes, or slots, in which the ends of the tubes of the bobbins are fitted.

The spacing between bobbin and bobbin present in the known art involves a low utilization of the available space, resulting in pallets packed with low filling density or with relatively low weights on available volumes.

Various sizes of reels and tubes are proposed on the market, therefore it is also necessary to have a plurality of specific cartons covering relatively narrow fields of application.

Pre-formed trays in plastic material having the imprint of the package have been proposed as means of interposition between layer and layer of reels.

However, with this solution there are still the problems of low filling density in the packaged pallet.

Once the overlapping layers of packages have been positioned on the pallet, everything can be suitably packaged using a wrapping of stretch film,

DESCRIPTION OF THE FOUND

The proponent has studied, tested and implemented a palletizing process capable of solving all the problems of the known art and providing a plurality of other advantages.

The invention is set forth in the main claim.

The related claims illustrate various characterizations of the invention.

The method according to the invention provides that the reels, coming from the respective production machines, are first individually arranged in protective bags, then positioned side by side on the various layers provided on the relevant pallet.

The bagging of the packages preferentially takes place directly and automatically in correspondence with the device for unloading the packages of the production machines.

However, said bagging can also take place in any other suitable place, where said bobbins can be conveyed for this purpose.

The bobbins thus bagged are then preferentially picked up by automatic means suitable for stacking them neatly in layers on the pallet with the interposition between layer and layer of a separator cardboard.

The packages can be deposited on each single layer according to predetermined sequences or in bulk.

Using the usual and widespread truncated cone bobbins, said bobbins can be arranged alternately straight and reverse, or with their front surfaces rotated by 180 ° with respect to each other, so as to optimize the occupied spaces.

This is possible since said bobbins can be arranged with the side walls in contact, said walls being protected by the bagging means.

As it is not necessary to keep the bobbins spaced apart from each other, the separation boards can consequently be without holes and can have a very limited thickness, having to constitute only the supporting and dividing means between one layer and another.

Once the bagged reels and cartons have been distributed on the relative pallet, the assembly is advantageously wrapped with stretch film for storage and / or shipping.

The advantages obtainable with the method according to the invention can be summarized as follows:

- protection of each cone positioned on the pallet against external agents and friction with the adjacent cones;

- maximum use of the available space, in particular with truncated cone cones;

- separation of the layers of packages by means of non-perforated cardboard with a thickness reduced to a minimum;

- elimination of the problems of precision positioning of the packages and cartons (to make the holes of the cartons coincide with the tubes of the packages), if the palletization is carried out by automatic means;

- Facilitation of the complete automation of the palletizing and packaging cycle;

- drastic reduction in the costs of the materials used in the packaging cycle per unit in weight of packed yarn.

conical on a pallet according to the known art;

- fig. 2 is a partial side view, according to the arrow A, of the layer of bobbins of fig. 1;

- fig. 3 schematically shows in plan the arrangement of a layer of conical bobbins on a pallet according to the invention; - fig. 4 is a partial side view, according to the arrow A, of the layer of fig. 2; - figs. 5 and 6 show a further arrangement of conical reels on a layer of pallets, respectively according to the known art and according to the invention.

DESCRIPTION OF THE DRAWINGS

In figs. 1 and 2 show a traditional arrangement of truncated cone packages 10 on a perforated cardboard 11 to form a layer of packages 10 placed on a respective pallet (not marked in the figures).

In this case, the bobbins 10 are arranged on several rows in an "inverted" position, that is with the larger front surface 12 facing the tip of each tube 13 cooperates with coordinated holes 14 present on the cardboard 11, as well as the base of the tube 13 cooperates in the same way with similar cardboard 11 (marked with broken lines in fig. 2).

The holes 14 serve to keep the reels 10 in a spaced position, so that they do not touch each other in the transfers of the packaged pallets.

In figs. 3 and 4 show a situation similar to that of figs. 1 and 2, but the bobbins 10 having been previously introduced into bags, indicated by way of example with 15 in fig. 4.

Said bags 15 can be of the known type, for example made of polyethylene closed with thermal sealing.

In the solution of the invention the bagged cones 10 are always arranged on several rows, but in each row the cones 10 are arranged either straight or upside down, and alternating row after row.

As said, by straight we mean the cones having the smaller surface 16 facing towards the bagging allows to arrange alternatively the cones 10 with respect to each other, being able to position them substantially with the lateral surfaces in contact in order to cover the spaces present between a row and the other of fortresses 10 and between fortress and fortress.

The lack of danger of damaging the bobbins 10 themselves allows them to be left "free" in the relevant layer, that is, it allows to use thin cartons without holes 17, since said cartons 17 must constitute simple supports for the bobbins 10 of the superimposed layers.

By way of example only, it can be indicated that, in the case of fig. 1, for pallets of usual dimensions equal to 800 x 1200 mm and with truncated cone packages with a maximum diameter in the range from 200 to 220 mm, each layer can contain up to fifteen packages 10, as shown in the arrangement illustrated in said fig. 1.

Under the same conditions, the situation of the invention (see Fig. 3) makes it possible to arrange four rows of bobbins 10 with five bobbins 10 per row, alternately straight and reverse, or a total of twenty bobbins 10 per layer.

Each layer therefore contains five more rolls 10, with the relative increase in weight per available area.

In figs. 5 and 6 show a situation similar to that of figs. 1 and 3, but referring, by way of example, to pallets of larger dimensions and to packages of an equally larger diameter.

The dimensions of the pallet can be the widespread 1000 x 1200 mra to house 10 reels with a maximum diameter included in the range from 220 to 240 mm.

In the solution of the known art (fig. 5) fifteen reels 10 can be positioned on a perforated cardboard 11, said reels 10 being arranged straight, while in the solution of the invention (fig. 6) twenty-three bobbins 10 can be positioned, with a further increase in weight per available surface relative to what is illustrated in figs. 1 and 3.

In fig. 6 it is indicated that in each row of bobbins 10 positioned, said bobbins are arranged alternately straight and reverse.
