Definitions

  • the invention relates to a device and a method for further processing of semi-finished sacks and a sizing station for semi-finished sacks.
  • Devices for further processing of semi-finished sacks are used in the production of various types of sacks.
  • methods for further processing of semi-finished sacks is meant that at least part of the processing steps that occur between the presence of the sack material and the emergence of the finished sack, part of the process.
  • the bags produced with the overall method include, for example, the so-called valve sacks, in which valve sheets are generally inserted in the production of the bottoms.
  • the bottoms themselves are often designed as cross bottoms, as shown for example in DE 090 145 48 U1 and DE 3020043 A1.
  • parts of the floors are glued to each other and / or with the valve leaflets with the help of glue.
  • either the areas of the bottom folds to be bonded or the pieces of paper associated with them, that is to say all areas to be bonded together, are provided with a glue trace and then glued together by joining or folding.
  • the order of a format-suitable glue track is usually done by a mounted on a rotating roller format part in one revolution of the roller brought into contact with a glue roller or other Leim arrived- or transfer parts and thereby applied with glue.
  • the format plate transfers the glue stored on it to the respectively to be bonded areas of the later bag bottoms or the slip.
  • the format part is provided with characteristic elevations, which are adapted to a specific sack format.
  • the format parts are exchanged. This type of production of flat glue marks on semi-finished sacks has proven itself, as such large quantities, including the difficult-to-handle starch glue, can be applied cleanly and in the right format.
  • size-appropriate glue line is to be understood as an order form tailored to the type and format of the bag The order within this order form generally takes place flatly, whereby the edges of the form often have special significance for the durability and tightness of the bags.
  • EP 1 648 688 B1 shows a bottom-laying device with a gluing station in which several application heads extrude glue onto semi-finished sacks.
  • several glue valves are mounted on each of these guns. These glue valves are assigned one or more glue outlet openings, from which the glue is applied to the bag components.
  • the effect of the order of a format-appropriate glue trace is now done by a control unit selectively activates these glue valves. In this way, a wide variety of glue profiles can be realized and the need to maintain a large number of format parts eliminated.
  • DE 103 09 893 A1 also shows such a teaching.
  • semi-finished sacks are components of sacks needed for their production.
  • these include pieces of tubing, and all sorts of slips, the term note here is also to include ground cover sheets.
  • These semi-finished sacks are - strictly speaking - components of hose pieces, as they do not yet have laid and glued floors.
  • Bodenlegevorraumen provided hose pieces with sack bottoms.
  • a gun is a glue application tool.
  • This glue application tool is usually - as shown in the aforementioned publications EP 1 648 688 B1 and DE 103 09 893 A1 - not rotated, but it is silent during the glue application, while the respective semi-finished bag is guided past the application head.
  • variable application images can be produced with such application heads. This can be done, inter alia, by the connection of valves or by changing the application width of a slot die.
  • a guide element in the sense of the present document is any element which is involved in the transport of the semi-finished sacks in the area in question a Bodenlegevorraum. As a rule, belts, rollers, rods and sheets are involved in the transport and the guidance. In the functional context in question, however, it is mainly those areas of the semi-finished sack that are to be glued. As a rule, the guide element will at least partially be in an operative relationship with the feed element. The feed element and the guide element define the feed area of the semi-finished sack to the gluing point (location or area of the glue transfer).
  • This feed advantageously also leads parts of the semi-finished sack, which are glued later and / or parts that are not glued. With open bottom squares, large parts of the bottom flaps are usually part of the sack components to be glued.
  • the guide element and the feed element need not enclose the entire semi-finished sack, but only parts thereof (see above).
  • inventive measures of the present document also meet the stated object, if no counterclaim as in the unpublished German patent application with the file number 10 2007 057 820 is present and if, for example, a gun sprays the glue and an incomplete glue application is avoided on bent over locations.
  • the semi-finished sacks between a tether or a support rod - which or on one side mostly rests centrally on the semi-finished sacks - and a mecanicselement- which on the other side of the Sack semi-finished is -, for example, a table top, out. From the tabletop are only the areas where the semi-finished sack enters the work area of a processing station, for example in the field of a scoring station and an embossing device (will be described below).
  • the processing stations also contain (specific) guide elements for the semi-finished sacks.
  • the area between tether and support element (Tabletop or processing station support element) is called guide region of the semi-finished sack.
  • the semi-finished sacks Before the semi-finished sacks are fed to the gluing station, they usually pass through a scoring station.
  • some areas of the semi-finished sacks are provided with a grooving to facilitate a later folding the same.
  • a grooving For cross floors, for example, two creases are made above and below the ground center line. The area between the respective score lines and the outer edge of the cross bottom is called the bottom flap.
  • the creases allow the bottom flaps - after gluing - to be folded back along the crease line. After grooving, the bottom flaps are no longer in the same plane as the area between the score lines.
  • At least one feeding element is provided, which is arranged upstream of the gluing place in the transport direction of the sacks.
  • This feed element defines together with the at least one guide element (often a table top) a feed region of the semi-finished sacks to the gluing gap, which tapers in the transport direction of the semi-finished sacks.
  • the at least one gluing station can be a gluing station for gluing the bottom provided with a valve flap.
  • the gluing station is suitable for gluing the bottom of the sack by its nature. Their retrofitting in a Bodenlegevorraum is ensured by a variety of mechanical and electrical interfaces to the relevant Bodenlegevortechnisch.
  • a gluing station can be constructed so that the means of transport, which leads semi-finished sacks through the retrofitted floor layer, can also reach through the gluing station.
  • a particularly preferred embodiment of the invention includes a further gap, preferably a nip, which is upstream of the feed element and the gluing gap in the transport direction of the bags and in which at least a portion of the surfaces to be glued with pressure.
  • the pair of rollers which forms this further nip is also called an embossing device. At least one roller of the roller pair can be driven separately. As it passes through the pre-embossing device, for example, the "protrusion" of the bottom flaps (previously caused by the scoring) is weakened by crimping the semi-finished sacks (within their original plane) in the nip.
  • the semi-finished bag which has passed through the pre-embossing device, again guided between the table top and a tether.
  • the distance between the table top and the holding strap is greater than the nip of the pre-embossing device.
  • only a part of the surface of the bottom square is guided between the table top and tether.
  • the guide area for the semi-finished sacks initially expands considerably after the pre-embossing device, in order to rejuvenate in the area of the feed element.
  • the expansion after the pre-embossing device is one hundred times the nip of the pre-embossing device, but preferably ten to fifty times.
  • the sack semi-finished product is usually guided without the strength of the guide region changing in the transport direction (for example, no taper).
  • the angle which the at least one guide element and the at least one feed element enclose with one another, in the tapered region between 1 ° and 45 ° is advantageously between 3 ° and 15 °. In a particularly advantageous embodiment of the invention, however, the angle is about 10 °.
  • the feed element is elastic. This means that the supply element is flexible under force and takes its original form after the end of the force.
  • the feed advantageously consists of sheet metal, advantageously made of spring steel sheet.
  • the gluing station comprises at least two glue application heads.
  • a feed element is also provided per glue application head.
  • the gluing station therefore comprises at least two feed elements for gluing an open bottom square.
  • the at least one feed element and / or the at least one guide element at the level of the feed element in the transport direction of the semi-finished sacks with recesses which it allow to detect whether there is unwanted material in the feed of the semi-finished sacks to the application head or to the gluing point. Often components of defective semi-finished sacks form such unwanted material.
  • a spreading of the semi-finished sacks before or in the feed appears advantageous. Further advantages can be achieved if the delimiting elements of the feed area itself, such as the feed element and / or the guide element, have surface structures such as slots, grooves or elevations which convey the corresponding spreading force to the semi-finished sacks when they move in the transport direction.
  • the force When processing semi-finished products with open mid-ground squares, the force should act away from the mid-ground line. It is cost-effective to design the abovementioned recesses in such a way that the surface facing the sack semifinished product receives these force transmission properties.
  • the recesses - similar to the slots, grooves or elevations - lead away in the transport direction of the semi-finished sacks from the bottom center line, when the feeding element supplies unfolded bottom squares.
  • a gluing station according to the invention which has at least one counter-layer and a feed element which tapers in the transport direction of the semi-finished sacks, should be designed such that it can be retrofitted to ground levelers of the state of the art.

Abstract

L'invention concerne un dispositif (64) et un procédé pour la transformation de produits semi-finis pour sacs (24), ainsi qu'un poste d'encollage (3,4) pour des produits semi-finis pour sacs. L'expérience a montré que, en particulier, les produits semi-finis pour sacs à structure plus complexe, tels que les tubes à carrés de fond dépliés et en particulier à carrés de fond dépliés et feuilles de valve déjà insérées, ont tendance à être encollés de manière incomplète et sont même endommagés dans une fente de buse lors de l'encollage.
