Definitions

  • the invention relates to a method for producing a liquid pack, the tubular side walls of which are made of plastic-coated carrier material, e.g. Paper or cardboard, the bottom of which is square and made by folding and sealing, and the opening of which is made of plastic and is molded onto the upper edge of the tube forming the side walls; wherein the coated paper for the tube in the form of a web is drawn off from a supply roll, cut into sheets and shaped into a tube, after which the lid is molded on and the base is folded and closed.
  • plastic-coated carrier material e.g. Paper or cardboard
  • the invention also relates to a device for producing such a liquid pack with a supply roll, conveyor devices for the paper web, cutting devices for separating the web into sheets, tube forming devices and conveyor devices for the sheets to further work stations.
  • the cover which is only made of plastic, can be of square or round design in cross section or in plan view. In a side view, the cover can be flat, similar to a disk, or can also be provided with a frustoconical part.
  • the carrier material web which is coated on at least one side with plastic, hereinafter referred to as paper web
  • the carrier material web is drawn off from a supply roll and fed to further work stations in this take-off direction, which is the same as the further conveying direction, e.g. for cutting, forming a tube and closing it.
  • the tube is closed by a longitudinal rope seam.
  • the longitudinal sealing seam and thus also the longitudinal central axis of the tube lie not only in the general conveying direction but also in the direction of the paper bevels, because in general the paper fiber is always in the longitudinal direction of the web in the case of a roll .
  • the devices, methods and liquid packs considered according to the invention are understood to work from the roll.
  • a package of elongated shape in which, for example, a liter or two liters of milk is packaged, transported and offered to the end user, has a certain softness of the side walls, which is not very annoying and difficult to use, but is from the manufacturer would like to be avoided.
  • edge protection In addition to the constant requirement of good tightness of the liquid pack, there is always the consideration of edge protection on the longitudinal sealing seam. You can in fact form a paper web into a tube and close it by means of its longitudinal sealing seam by overlapping the two free longitudinal edges of the web or by sealing the inside on the inside. The forces arising from the filling material are better absorbed by the overlapping sealing seam.
  • a cut edge protrudes into the interior of the package, the cut separating the plastic coating or the carrier material, preferably the paper, being freely exposed to the filling material at the cut edge. The liquid can penetrate the paper fiber, soften it and destroy the package. For this reason, a separate strip is placed on the inside along the overlapping sealing seam as edge protection. It goes without saying that the application of a special strip is gladly avoided, especially since other sealing strips are also applied in particularly critical folding areas and the like.
  • the compressive forces of the filling material can cause injury and tearing of the sealing seam to the outside.
  • the invention has for its object to provide for the production of packaging as a mass product and also for the liquid packaging operation processes and high-performance machines, the performance of which is above that of conventional machines.
  • the conveying direction of the separated paper sheets is provided transversely to the feed direction of the paper web before being separated into sheets (first position), at least two conveyor tracks are provided in parallel next to one another, and in that during forming of the tube and production of the longitudinal sealing seam over a folded edge with the bow connected strip-shaped end is formed, folded around the folded edge by 180 ° and also the outer surface of the sheet is sealed, after which the opposite, free end of the sheet is sealed onto this strip-shaped end to form the longitudinal sealing seam.
  • the first measure means arranging the paper fiber direction transversely to the longitudinal rope seam or transversely to the longitudinal extension of the tube. It has been shown in an advantageous manner that the finished package in the transverse paper fiber direction has a higher stiffness when gripped by the end user, and can even be up to twice the stiffness compared to the longitudinal paper fiber direction.
  • a single supply roll can also be used to feed several adjacent production lines.
  • the further measure according to the invention with the folding of the strip-shaped end onto the adjacent outer surface of the arch and the subsequent sealing of the opposite free end of the arch creates a new structure for the longitudinal sealing seam, in which neither the mentioned edge protection nor the longitudinal sealing seam with the strip-shaped seam being laid one on top of the other
  • the butt weld must still be created from the inside to the inside. It is mechanically manageable to connect the strip-shaped end to the sheet via a folded edge, so that after preforming this folded edge, the strip-shaped end can be folded over onto the outer surface of the sheet and sealed without difficulty. After completing this preparation, the opposite free end of the sheet can then be sealed onto the strip-shaped end with difficulty, forming the longitudinal sealing seam.
  • the method according to the invention is particularly advantageously further developed in that the tube is formed from the isolated, flat sheet in two stages, the sheet being conveyed from its first position to a second position, about half of which is curved and semicircular about its longitudinal central axis promoted to a third position in the second stage, where the remaining part of the arch is bent to complete the tube.
  • first stage approximately a first half, preferably slightly more than the width of the flat sheet, is bent in a semicircular shape, so that practically half of the tube is thereby finished.
  • the above-mentioned strip-shaped end can, however, also lie in exactly one half of the width of the flat sheet in another embodiment, because the opposite end, which is sealed onto the said strip-shaped end to form the longitudinal sealing seam, forms the same excess on the opposite side.
  • the arc can be divided exactly into two halves, the first half being formed in the first stage in the shape of a semi-cylinder and then the remaining second cylinder half being formed in the second stage. Then the tube is completed.
  • Devices for producing a liquid pack are known. Such devices have a supply roll, conveyor devices for the paper web, cutting devices for separating the web into sheets, tube forming devices and conveyor devices for the sheets to further work stations.
  • these devices work "from the roll” in such a way that the conveying direction once intended as the withdrawal direction from the roll is maintained until the tube is created, i.e. the paper feed direction is in the longitudinal direction of the finished tube.
  • DE-A-2512 852 describes a production machine for tubes made of cardboard. However, these tubes are not sealed on either side, rather they represent packaging for bottles or are intended for the production of boxes.
  • Two mold jaws pivot about a pivot axis that has to be moved in translation.
  • a mold jaw with an intervening arch is pivoted on a mandrel so that one half of the arch wraps around one half of the mandrel, after which the other arch folds over the other half until the arch edges overlap.
  • the two halves of the respective sheet halves are folded, the sheet is closed and glued, and then the tube is pulled off from this production position.
  • a high-performance machine cannot be manufactured with this.
  • means are provided according to the invention to increase the rigidity of the package and thus to improve the hold by the end user.
  • device parts are created according to the invention, with which, despite the increased rigidity of the individual bow and the tube, inexpensive measures can be created in order to achieve a high throughput to create wall-free solid and economically producible longitudinal sealing seams.
  • the novel longitudinal seal seam is created by the mandrels which are arranged lying in the conveying direction of the sheet.
  • each is a mandrel around which the folding lever can be moved such that the sheet initially lying underneath the mandrel can be placed flat on the mandrel surface.
  • the cross section of the cathedral can be polygonal or round.
  • the mandrel like the preferred embodiment of the tube, will have a cylindrical outer surface. Based on this, a more detailed explanation of the invention is given, although a square or rectangular shape in cross section is also conceivable. The measures according to the invention are independent of this.
  • the strip-shaped end for preparing the longitudinal sealing seam can be created and thereby sealed onto the tubular outer surface of the arch in such a way that a smaller movable part of the pressure jaws, compared to the stationary, non-movable mandrel, performs the folding over of this strip-shaped end. If, in the first stage with the mandrel, not only is the arch half-shaped to the tube, but also the stripe-shaped end is sealed onto the adjacent paper outer surface next to the folded edge, conveyance takes place in the second stage, whereby the tube is pushed further on the mandrel .
  • the already pre-formed tube half is held by a folding lever that encompasses the mandrel, and an opposing folding lever now forms the second half of the arc tube-shaped.
  • the free end of the sheet is over the sealed strip-shaped end, i.e. sealed over the resulting thick bar.
  • the two folding levers do not encompass the cylindrical mandrel, for example, by a full 360 °, but instead keep a distance from one another in the region of the thickened strip (strip-shaped end), in which a hot stamp can be inserted and the longitudinal sealing seam can ultimately be completed.
  • the further preferred embodiment of the device for producing the liquid pack described above is characterized in that a folding lever is provided in the second position, encompassing the mandrel flat, rotatably driven about axes, and two opposing folding levers in the third position, encompassing the mandrel likewise flatly, are provided rotatably driven about an axis.
  • the cross section of the mandrel can be polygonal or round, and the cover can also be polygonal or round in plan view.
  • the embodiment in which the mandrel is essentially tubular is particularly preferred. Such a design even allows the block bottom to be closed at one end of the tube and a round or polygonal cover to be molded on at the other end of the tube.
  • the cross section of the mandrel is round, preferably circular.
  • the cutout of the dome in the second position takes up less than one quadrant in cross-section and accommodates at least part of the pressure jaw, which is approximately sector-shaped in cross-section, if the pressure jaw is rotatably driven about a longitudinal outer edge of the mandrel and if a heating jaw is provided radially to the longitudinal outer edge and movable away from it.
  • the aforementioned first half of the initially flat sheet of coated paper is folded over by means of a folding lever in such a way that a folding edge comes to rest against the longitudinal outer edge of the mandrel.
  • the strip-shaped end then protrudes from this.
  • a favorable further embodiment of the invention is characterized in that the conveying device for the separated paper sheet from the second position into at least one of the following positions has oscillating transport sleeves and vacuum surfaces on carrier shafts extending in the conveying direction.
  • Such a configuration of the conveyor is reliable, simple and controllable at high speed, so that the manufacturing machine can obtain high performance.
  • the paper sheet lies on a hollow shaft, which can also have vacuum openings at the same time, can be held in place by switching on the vacuum, processed and then transported by the moving transport sleeve.
  • the paper web only has to be pulled off the supply roll by a correspondingly longer piece, after which the desired number of sheets is separated by the corresponding number of cutting knives, scissor-like cutting devices or the like and can be moved on in the desired transverse conveying direction.
  • it is desirable to continuously remove the web especially since this web may also have to go through further preparation steps before being separated into sheets of paper.
  • a plastic strip may have to be sealed in the folding area, the application of which does not take place in an intermittent manner.
  • the arrangement according to the invention of two separate conveying devices makes it possible to provide a supply loop between the first and second conveying devices, so that the paper web with the preparatory work steps can actually be continuously withdrawn from the supply roll while the separating device can be fed intermittently.
  • the paper web 101 runs in the direction of arrow 2 via a first deflection roller 3, a second deflection roller 3 'with the take-off roller 4 (first conveyor device), a third deflection roller 3 "and finally a fourth deflection roller 3"' with counter roller 5, wherein the roller 3 "'is at the same time a drive roller which interacts with the driven counter-roller 5. While the drive roller 3"' is driven intermittently, the pull-off roller 4 is driven continuously, so that a supply loop 12 between the deflection rollers 3 'and 3 " is created and can move up and down.
  • the roller 3 "'simultaneously carries embossing lines and applies embossing to one edge of the web 101. These embossings can be seen, for example, on the finished web 101 at point 6 where the web 101 lies flat.
  • a pure plastic film strip 7 for example in the bottom area where folding and welding is carried out, is continuously applied to the lower edge of the web 101, on which the embossing described later is then applied as shown at 6.
  • This plastic film strip is preferably a polyethylene strip 7, which is pulled off a roller 9, held against a counter roller 10, the roller 9 being heated by suitable means.
  • a hot-air blower can also be used, which hot air is blown in according to arrow 11 into the gap between the roller 9 and the web 101 to be coated.
  • the drive roller 3 "'with the counter roller 5 thus intermittently pushes the web 101 forward according to arrow 13 at a fairly high speed over a distance of four cylinders. Then the web 101 is brought to rest. At four points, one of which is shown in FIG 1 is designated 14, the web is cut by separating the paper sheets 15. Thus, for example, a web section or a sheet 15 lies flat in position 1.
