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.

- Glue plant 1 is the application head 3 with the nozzle bar 4, which counteracts the counter-5 mechanically.
- the counter-layer 5 is designed as a rotating roller whose active surface 6, which is in contact with the back 7 of the
- FIG. 2 shows another view of the counter-layer 5 of FIG. 2, which shows that the effective surface 6 is divided by slits 10 into surface segments 11. This subdivision makes possible a better sizing of sack components whose surfaces are textured and have a characteristic topography with significant height differences.
- the configured as a roller counter 5 has pins 13, where they can be stored 5.
- FIG. 3 another embodiment of a gluing station according to the invention is shown, which also has a gun 3 with a
- Nozzle strip 4 with which the bag components 2 are glued.
- Angle ⁇ is the angle at which the sack components in the from the nozzle bar
- Backing 5 is shown stylized in FIG. 3 and can be realized in the form shown in FIGS. 4, 5, 6 and 11.
- the bands 14 are those elements which define the active surface 6 of the counter-layer 5. Those surface components of the bands 14 which come into contact with the sack components 2 when they are passed over the bands 14 form the active surface 6 in this case.
- the bands may be guitar strings which, as in FIG. 4, are oriented substantially parallel to one another and below a certain (low) mechanical tension.
- the guitar strings or bands 14 are hinged to the legs 15. It is also advantageous in this embodiment to align the bands along the direction of travel of the sack components.
- the active surface 6 formed by the bands 14 is already segmented because the bands are spaced from each other.
- FIG. 6 shows a further gluing station with another counter-layer 5, which again has tapes 14, whose surface components touching the bag components 2 form the active surface 6.
- the bands are guided by the guide rollers 16 and in the direction of movement z of Sack components 2 moves.
- the thus guided bands are doctored off again by the doctor device 8 with the doctor blade 9.
- FIG. 5 shows the effective surface 5 formed by the belts 14 running on the guide rollers 16 from the point of view of the application head 5.
- Figure 7 shows the bottom 17 of a Buch Guineaventilsackes 18.
- the figure should be clarified that the FaIt- and material edges of such a bag floor have height differences. In view of these height differences, the application of the counter-layers 5 shown here is particularly advantageous.
- a counter-5 is shown, which consists essentially of a
- This roller exists.
- This roller has a segmented active surface 6, which is divided by slots 10 into surface segments 11.
- the surface segments are made of an elastic material, which is the lateral surface of the
- the roller has a clamping strip 19, which can define a sack component - especially a slip - on the roll surface.
- the possible clamping movement of the terminal block 19 is shown by the arrow 21 in FIG.
- Figure 9 shows how a piece of paper 20 is transported on the active surface 6 of the counter-5.
- FIG. 11 shows, from the point of view of the nozzle head 5, a further active surface 6 with surface segments 11 which are delimited by the slots 10.
- the bag components 2 facing surface of the bag components 2 is flexible.
- the surface segments themselves are employed by spring elements on the side facing away from the bag component against the bag component. Also in this way a point-elastic adjustment of the bag components against the nozzle bar 4 is achieved.
- FIG. 12 indicates a further possibility for guiding the sack components 2 in a gluing unit 1.
- a counter-layer 5 which largely corresponds to the counter-layer 5 from FIGS. 5 and 6, is shown from the perspective of the application head 3.
- the bands 21 are shown, which are located from the viewpoint of the nozzle head in front of the bands 14 of the counter-layer.
- the bands 21 are displaceable in their position in the direction x transverse to the transport direction z of the bag components 1.
- the mobility is ensured with customary measures, such as a slidable suspension of the rollers that guide the bands. It is advantageous to adjust the spacing of the bands 21 relative to one another in such a way that the transported sack components are detected by the bands in their end regions in the x-direction.
- FIG. 13 shows a sketch of the semi-finished bag transport in the region of the gluing gap 43 in a ground-laying device 64 according to the invention.
- the semi-finished sacks 24 are transported in the conveying direction z.
- the bottom of the bag 17 is raised in the bottom opening station.
- the bottom flaps 47 of the raised bottom squares 51 are now guided along the transport path 50 between the guide element 25 and the holding band 32 through d.
- An exception to this type of guidance are only the areas of the individual processing stations 26,27,3. In general, however, the force for the transport of the tube pieces 24 is applied by the transport belt 42.
- the semi-finished sacks 24 enter the scoring station 26.
- the scoring station 26 two scoring lines are then impressed above and below 31 parallel to the sack bottom center line 28.
- the bottom flaps 29 of the sack 17 produced by the scoring are in Roll nip 63 of the Vorgargevorraum 27 smoothed.
- the feed includes an angle ß with the guide member 25 of the semi-finished sack 24 a.
- the angle ß and the length of the feed element must be selected so that the bottom flaps of the sack bottom can run without contact in the feed region 41 of the guide element 33 and the triangular pockets are pressed as slowly as possible to the feed element 33. Therefore, the angle ⁇ in the embodiment shown here is between 5 ° and 12 ° and the length of the feed element is between 200 mm and 300 mm.
- the parts of the semi-finished sacks, which reach the effective range of the feed element 33, are exposed to a continuously increasing pressing pressure. After leaving the feed area 41, the components of the semi-finished sacks 24 to be glued reach the gluing gap 43. It is no longer shown that the squares of the floor are increased after leaving the gluing gap 42 and thus form sack bottoms.
- Such sack bottoms are usually provided with bottom cover sheets (further sack semi-finished products), which can be done in the same manner as the sizing of the open bottom squares 51st
- FIG. 14 shows the detail from FIG. 13, which is located in the dashed rectangle 48.
- a guide element 25 may be any device component that guides or transports semi-finished sacks 24 to the application head 3.
- the guide member 25 is a tabletop.
- the guide area 65 is the area of the floor leveler 64, in which parts of the unfolded floor square
- This area 65 thus extends in the transport direction of the bottom opening station 40 to the not shown assignment of the
- Guide elements which include the semi-finished sack while driving, there (usually in the x or y direction) have. Large parts of the guide area 65 are identical to the transport path 50 of the bottom flaps 47.
- FIG. 15 shows the viewing area 55 (FIG. 13) from the perspective sketched by the arrows 54 (FIG. 13).
- the unfolded bottom square 51 of a semi-finished bag 24 was not shown in Figure 15.
- the further transport of the semi-finished bag or the way the bottom center line 28 through the gluing station is represented by the dashed line 56 (transport path of the bottom center line 28) , From the gluing station, only the guide element 33 and the application head 2 can be seen.
- the recesses or slots 44 point away from the bottom centerline 28.
- the longitudinal axis 66 of the recesses or slots 44 includes the bag bottom center line 28 at an angle Y.
- the angle Y is approximately between 0 ° and 10 °, preferably between 3 ° and 8 °.
- the width 67 of the recesses and slots 44 is approximately between 3 mm and 20 mm, advantageously, however, between 4 and 12 mm.
- the recesses 44 impart to the bottom flaps 47, when transported in the z direction, a force pointing away from the bottom center line. This force F tightens the semi-finished sacks 24 and is advantageous. In general, it is positively noticeable when the spreading force F is imparted in the feed area 41. This can be done by the surface structure of the elements 33, 25 delimiting the feed area 41. In FIG.
- FIG. 16 the type of transport of the semi-finished sacks 24 between the bottom opening station 40 and the location at which the glued bottom squares 51 are added is shown once again. Viewing direction 53 and viewing plane 52 on which FIG. 16 is based are shown in FIG. It can be seen that the bottom flaps 47 of the open bottom squares 51 are raised and guided by the guide elements 25. On the right side of Figure 16, a valve sheet 57 is placed on the bottom square 51. The Ventilzettelbeleimungsstation performing this activity is shown in any figure. In order to guide the valve sheet optimally, the holding and conveyor belt 32 is provided. The guide rollers for this band 32 bear the reference numeral 62. On the other side, the bottom side 60 of the bottom layer 64, no such band 32 is provided in this embodiment.
- FIG. 16 it has been dispensed with to represent machine elements which lie behind the viewing plane 52. An exception is the leading edges of the feed element 33 shown. Therefore, it can be seen that the feed elements 33 have their effective range, especially in the area of the bottom flaps 47 of the unfolded bottom square 51. It should be noted that the distances between the bottom flaps 47, valve leaflets 57, guide elements 25, guide strips 32, etc. are shown exaggerated for illustrative reasons. In FIG. 16, feed elements 33 have been shown on both sides of the semi-finished sacks 24 (bottom of the valve and bottom of the stand). It may also be useful to provide feed elements 33 only on the valve bottom side 59.
- the middle region of the sack semi-finished product 24 - in this case the region of the hose piece which later forms the sack walls - in the illustrated type of transport between the conveyor belts 42 is merged.
- the conveyor belts 42 usually transfer the force necessary for transporting the semi-finished sacks 24.
- the holding and transport belt 32 may also be driven.
