Definitions

  • sacks include cement bags, which are usually manufactured as valve sacks.
  • valve leaflets are usually introduced in the bottom folding in the soil.
  • glue - usually starch glue - formed.
  • the gluing of the components to be glued each of the bag is usually carried out by a mounted on a rotating roller format part - often called cliché - brought in a revolution of the roller with glue rollers or other Leim arrived- or transfer parts in contact and thereby applied with glue ,
  • the format plate transfers the glue stored on it to the respective bag component to be glued.
  • the format part is provided with characteristic elevations, which are adapted to a specific sack format. If sacks with other dimensions are to be made on the Bodenlegevorraum, the format parts are exchanged.
  • the illustrated type of glue application has been proven in the Bodenlegevorraumen for paper sacks, as can be applied in this way, large amounts of hard-to-use starch glue clean.
  • this type of glue transfer necessitates the provision and subsequent cleaning of a variety of mechanical size transfer components, such as the cliché roll and size parts.
  • pamphlets DE 100 53 064 A and US 2002/079327 disclose devices that operate on the same principle.
  • a further advantageous embodiment of the invention has a plurality of glue outlet openings, which are provided on a glue application head.
  • FIG. 1 shows a glue application device, as used in the prior art usually for gluing of soil sheets 2.
  • glue is transferred from a glue cylinder 11 to the format part or plate 12, which is supported by a plate cylinder 13 and about the axis of the plate cylinder 13 in the arrow 16 sketched direction is moved.
  • the cliché or format part 12 transfers glue to the bottom sheets 2, which are carried by the pliers cylinder 14 during the glue transfer.
  • FIG. 3 shows a sketch of a Zettelbeleimungsstation 30 of a cross-bottom layer according to the invention, which already segregated notes 2, which are conveyed in the direction of arrow x, provided with glue marks 3.
  • the gluing station 30 is equipped with an application head 31.
  • This gun is supplied with the help of the hose 33 with glue.
  • the glue is distributed in the interior of the applicator head 31 by suitable glue lines on the valves 32, which are mounted on the applicator head 31 in two rows, which extend transversely to the conveying direction x of the slip 2.
  • These valves 32 are at least able to release or prevent the glue flow. They are controlled by external - preferably electrical signals and they can withstand the glue pressure.
  • FIG. 4 shows a gluing station 40, which externally as well as the gluing station 30 from FIG. 3 is constructed.
  • the different glue tracks 44 to 47 show that a wide variety of adhesive formats can be realized with such a device without having to use format parts. In this case, a variation of the cliché width, that is to say the extent of the adhesive surface in the y direction, can be achieved by disengaging or connecting valves 42 during the production of sacks of this adhesive format.
  • valves that are active in the production of an adhesive format, closed after the production of a continuous glue trace 47 and 48 are opened at the arrival of the next still unglued billet 48 at the glue outlet openings.
  • this sequence of operations leads at industry standard Beleimungs Malawien to considerable demands on the switching time of the valves 32.
  • the valves 42 must be opened or closed even faster than in the production of continuous glue traces 47th ,
  • a substantial variation of the applied amount of adhesive is possible in particular by the application of multiple interrupted glue traces 44.
  • the further variation of the shape of the adhesive format - which includes distinct deviations from the rectangular shape - requires the application of short 45 and discontinuous glue marks 46.
  • the adhesive formats 4 it is often necessary for the adhesive formats 4 to be in the form of a "u" 4a) or rectangular frame 4b ), like that in the FIGS. 9 a) and b) will be shown.
  • a different control of the valves during the gluing of a bag component 1, 2 to be glued is necessary. It is advantageous if the valves provided in the bottom-laying device have a switching time or are switched in a time which is less than 5 ms. Then, a large part of the variations of adhesive formats required in the industry, which can be achieved by changing individual glue track lengths in the x-direction, can be realized in the manner described above at the usual gluing speeds.
  • the different glue tracks 45 to 48 give an idea of how flexibly such a device according to the invention can generate formats when the valves are switched even faster.
  • the in the Figures 3 and 4 Illustrated embodiments of the invention are already isolated to the actual gluing shown slip 2 just as suitable as for gluing paper webs, which can later be separated. Even with sack bases 1, the gluing can be carried out analogously.
  • the channels could as well have a different shape.
  • the glue channels 52, 53 rise in the vertical direction z to each valve glue channels 55, through which the glue passes directly to the valve 32.
  • the two glue channels 52 and 53 may be connected to the front side of the head opposite the glue feed lines by a further glue channel which runs in the application head 50 in the x direction.
  • the glue for example, via the glue channel 52, which is provided for this purpose with a feed line to run, flow through the connecting channel and flow through the glue channel 53, to finally run off by a Leimablauf.
  • a Leimzirkulation would be possible by such a gun.
  • FIGS. 5 a) to c) waived was in the FIGS. 5 a) to c) waived.
  • FIG. 7 a) shows a way to make the sack components 1, 2 facing side 76 of an applicator head 70.
  • the application head 70 essentially consists of a valve mounting plate 75 on which the valves 32 are located.
  • the glue outlet openings are located on a line which here runs orthogonally to the conveying direction x of the slip 2.
  • the holes 71 in the x direction at the same height.
  • FIGS. 8 a) to 8 c) Illustrated in plan views of an embodiment, the movability of an applicator head 80 in the y-direction relative to the sheets 2.
  • This embodiment of the invention opens up further possibilities of variation in the area of the resolution and the format width and thus further increases the flexibility in the free design of the adhesive profile 4, without necessitating the exchange of format parts.
  • the mobility is apparent from the location of the center lines o and p shown for illustration, which the application head 80 and the Go through piece of paper 2 in the middle. In FIG. 8a ) these two lines are aligned.
  • a relative displacement of the applicator head 80 relative to the slip 2 has taken place. An extensive presentation of a displacement mechanism was omitted here.
  • the U-shaped glue format is composed of continuous 3 and short glue traces 45.
  • the glue format in the form of a rectangular frame 4b) is composed of continuous 3 and interrupted glue traces 46.
  • the different course of the glue traces comes about by a selective control of the glue valves 32 during the gluing of a sack component 1, 2 to be glued.
  • no pumps or pressure vessels have been shown which are usually necessary to convey the glue and to build up or maintain the necessary glue pressure for extrusion. All shown and described by the subclaims embodiments of the invention are also suitable for an indirect gluing of sack components 1, 2 in which the glue is first transferred to a roller or other form before it reaches the sack components.
  • a channel system may also be a multi-channel system 115.
  • the main purpose of such a channel system is the distribution of the glue on several outlet openings. This is even more important because the distance between the outlet openings is usually less than the width of the valves. The cost of the valves are high and justify the use of such a channel system. It can therefore also happen that several channels are supplied with glue from a valve. The channels can then distribute the glue to a plurality of outlet openings. In the illustrated embodiment, the adhesive or glue from the channels 115 passes into the outlet openings 113.
