Definitions

  • the invention relates to a device and a method for producing packs filled with liquid, with a device for shaping a paper web having a thermoplastic coating to form a tube, which can be pushed vertically from top to bottom in the device, with a longitudinal and a transverse embossing device.
  • sealing jaws which can be moved in the horizontal direction and interact in pairs, for transverse sealing of the tube when it is stationary, at intervals corresponding to a pack length, and with a pair of cutting blades arranged one feed step length below the sealing jaws for separating the package from the tube in the region of a transverse weld seam, a forming station below a feed device and the cross-embossing device are arranged above the same and the molding station has the respective pack encompassing movable metering elements on all sides, which between the cross-sealing jaws and the pair of cutting blades are arranged.
  • a similar device of the type mentioned above is known from DE-B-1 218 332 (HABRA).
  • the feed device provided below the cross-embossing device in this known device is, however, merely a conveying aid which, by itself, is unsuitable for the paper feed.
  • the actual feed device is located above the cross embossing device.
  • the most important disadvantage of the known machine lies in the fact that not every type of pack can be processed, although the known shaping station also has movable metering jaws encompassing the respective pack on all sides.
  • these have the shape of measuring cups, in which, in the case of a large number of pack types, a seam which protrudes lengthways on the side is disruptive. This protruding side seam is in the way during molding, so that it cannot be properly welded tightly because the measuring cup shape creates a sharp kink at the seam and this kink jeopardizes the tightness.
  • Certain cuboid packs can be processed with the known device in which the longitudinal sealing seam is not arranged at the edge. With these types of packaging, however, care must again be taken to protect the edges, otherwise liquid can seep into the cut edge area in the overlapping sealing seam and cause it to swell. There are also dangers of leakage at the intersection of the longitudinal and transverse sealing seams.
  • the object of the invention is therefore to improve the device and the method of the type described in more detail above in such a way that all common liquid packs can be filled in a metered manner with transverse and longitudinal sealing seams without there being any particularly critical points during sealing.
  • the mechanically interconnected metering elements have two support plates pivotable about a horizontal axis from a horizontal position into an obliquely downward inclined position, as well as two longitudinal and transverse metering jaws which also move from horizontal to vertical axes are tilted obliquely downward position.
  • the device for the invention is built vertically so that the tube of the Paper web provided with longitudinal embossing lines from above initially runs into the cross-embossing device, in which it receives the embossing lines arranged transversely to the direction of movement of the running paper web as well as the obliquely arranged embossing lines.
  • the tube of the paper web then runs through the feed device and, downstream, the forming station.
  • the transverse embossing device creates the conditions for the novel shaping station to reliably ensure that the liquid pack to be formed is perfectly formed at a high work cycle. What is special about the new shaping station is the fact that the dosing jaws encompassing the respective pack are stored and movable in a special way.
  • the shut-off device of the device known from DE-A-21 31 906 has been dispensed with, so that the liquid stands above the fresh transverse weld seam earlier, but only with a thin liquid column, the closed state of which is ensured according to the invention, that the dosing jaws are moved towards one another at their respective lower edges and are held in such a position that the only partially preformed package remains in a precisely defined, stretched state.
  • This advantageously prevents an undefined bulging of the parts of the paper tube which give the later side walls.
  • the hose Due to the movable longitudinal dosing jaws and the narrow dosing jaws that can be rotated transversely to it, the hose is practically supported from four sides, whereby the size of the surfaces can be set up by appropriate arrangement of the dosing jaws so that the later dimensions of e.g. parallelepipedic pack can result.
  • the pivoting of flat jaws about axes of rotation is a simple measure, so that this results in reliably controllable and reliable partial structures of the device according to the invention.
  • the liquid slowly filling the pack and pushing it apart in the upper region can adapt to the desired stretched state of the partially preformed pack.
  • This in turn eliminates the undesired, lateral and undefined bulging of the paper web.
  • This advantageously results in the pair of cutting blades always meeting and cutting the transverse sealing seam at the desired height, preferably in the middle, at the bottom.
  • the sealing seam located at the bottom of the pack separates the bottom pack, which is finished at the bottom closure, from the top pack, which is only partially preformed in the upper area, so it has to be severed in such a way that after separation, both the lower and the upper pack are still absolutely liquid-tight .
  • the liquid pack being manufactured can be kept stretched during sealing in such a way that the sealing seams are arranged in perfectly flat cardboard levels.
  • much more precise dosing is possible because the longitudinal and transverse dosing jaws compress a pack that has fallen to the exact height into the desired final shape.
  • an adjustable pressure stamp is arranged in at least one dosing jaw.
  • the embossing lines also take into account the applied pressure are always exactly in the right place, it is also advantageous if the embossing lines along which the package is folded in the shaping station and later finished in the final shaping station are brought to the desired location by the correct means. With the longitudinal embossing lines, this poses no difficulties.
  • the cross embossing lines can shift disadvantageously if the setting or feed is inaccurate.
  • the transverse embossing device is fixed in a stationary manner on the machine frame and has two shells which are rotatable synchronously with one another and which have the packing web between them, circular in cross-section and have grooves and webs on the circumference, one of which has a belt or a chain is driven, on which a part attached to the feed device is attached. It is easy to drive the other embossing tray not driven by the belt with the first one, e.g. in that both shells are arranged on shafts provided with gear wheels.
  • one of the shells is mounted eccentrically and the eccentric is controlled pneumatically.
  • the rotary shafts of the two embossing rollers are separated from one another so that they can move back in the opposite direction to the embossing direction, while the paper web remains between them.
  • a particularly simple, robust and therefore reliable construction is selected, in which an eccentric is connected to a pneumatic drive on the drive embossing roller via a lever, in which an increase in the roll gap takes place via compressed air control from the outside at the moment of bottom dead center, which continues until the end of the return stroke until top dead center. Then the distance is reduced to the working size, so that the paper web can be provided with embossing lines in the desired manner during feed.
  • the shells are designed as half shells.
  • the embossing rollers e.g. completely out of engagement with the paper web on the return stroke.
  • a device for rotating processing of conveyed paper webs by punching or printing is already known, in which the work rolls, one of which has a flattening, are stopped, so that when the flattening is arranged next to the paper web, it is at least disengaged from the one work roll.
  • the work roll is, however, provided to oscillate freely about its axis and is caused to rotate uncontrollably by a weight after the locking is released. As a result, this device cannot work synchronously.
  • the known device has the disadvantage that the engagement of the punch rollers is actuated by the paper web itself.
  • the parts of the shaping station are controlled in relation to one another in the working cycle of the device such that, after cutting through the transverse sealing seam, the bottom closure of the package formed above is held by the support plates, which pivot upwards into the horizontal while shaping the bottom closure , while the dosing jaws move apart in synchronized movement, then the sealing jaws of the transverse sealing device then close and weld, after which they move apart, that while the closed package is pushed down between the downwardly pivoted support plates, the dosing jaws swivel towards one another and liquid into the stretched, partially formed package flows against the side walls of the pack supported by the metering jaws, and that the transverse sealing seam is then cut again.
  • the paper tube is pulled down by the feed device, so that the liquid slowly begins to fill and expand the tube.
  • the dosing jaws which converge obliquely downwards, prevent transverse pressure from tearing apart the transverse sealing seam. Nevertheless, the liquid can flow more and more into the freshly formed package.
  • control according to the work process described above enables a faster work cycle because the liquid can flow in during the feed and therefore takes less time to finally fill the package, while the fresh cross seal is not loaded and is instead held by the support plates.
  • the packaging machine shown partially schematically in FIG. 1 consists of the vertical main part in the left half and the conveyor chain with the end forming stations, which is or are shown at the bottom right.
  • the Katte are designated with a total of 1 and their drive with 2.
  • the vertical part is driven by the motor 3 via the gear 4 and a vertical drive shaft 5 which extends into the upper area of the machine and is mounted at 6.
  • the shaft 8 of the material roll 9 of the paper web 10 is mounted, which is shown with a dash-dot line in a U-shape from the material roll 9 via the deflection bend 11 on the other side until it is pulled down shortly over the conveyor chain 1.
  • the deflection bend 11 is pivoted about the pivot point 14 with the aid of the push rod 13 via a transmission linkage attached to the frame 7 and designated with a total of 12 above.
  • the cross-embossing device generally designated 15, the longitudinal welding station 16, the paper feed device 17, the cross-welding device 18 and the automatic shaping station 19 with the movable dosing jaws are shown in sequence.
  • the separated package 30 falling down after leaving the molding station 19 is shown in perspective in FIG. 2.
  • Your bottom closure 31 is fully formed except for the protruding tabs 32, while the upper closure 33 is still stretched. This later forms the rectangular box that is used for packaging milk.
  • the transverse sealing seam 34 can also be seen at the top and at the bottom and the longitudinal sealing seam 35 at the rear right.
  • transverse sealing station generally designated 18, and underneath, the molding station 19.
  • the sealing jaws 43 are held on a carrier 41, which is arranged on both sides of the paper web 10 and can be moved back and forth in the direction of the double arrow 42, by means of unspecified ones Screws connected to the carrier 41 so that they move in the direction of the double arrow 42 just like the carrier.
  • screws connected to the carrier 41 so that they move in the direction of the double arrow 42 just like the carrier.
  • transverse sealing seam 34 they move towards the paper web 10 and press it between them in the manner shown in FIG. 3.

  • the blades 50 shown are severed in the middle to form the two transverse sealing seams 34 mentioned.
  • the shaping station 19 which, in addition to the device with the pair of cutting blades 50, consists essentially of longitudinal metering jaws 51 and transverse metering jaws 52 and two support plates 53.
  • 3 shows the two longitudinal metering jaws 51 which can be pivoted about the axes 54 and which abut against the longitudinal side walls 37 of the pack 30 shown in FIG. 2, while around axes 55 arranged transversely to the axes 54, a transverse metering jaw 52 on each side against the narrow side walls of FIG Pack 36 comes into contact, of which only the left transverse metering jaw 52 is shown in FIG.
  • the metering jaws 51 "52 are driven mechanically via tie rods, lever gears, etc., of which only the tie rod 56 is shown in FIG. 3, which is attached to the left metering jaw 51 so that it moves in the direction of the curved double arrow 57 around the axis 54.
  • the support plates 53 which rotate about the axes 60, are driven in a similarly pivotable manner, specifically from the horizontal position shown in solid lines in FIG. 3 to the position shown in broken lines, that is to say corresponding to the curved double arrow 61.
  • the dashed position of the pack is reached between the metering jaws 51, 52.
  • the longitudinal and transverse metering jaws 51 and 52 move inwards from the position shown, around the position with To support and hold liquid-filled, thin tube of paper web 10. It goes without saying that the support plates 53 pivot downward at the same time, so that finally the positions of the pack and dosing jaws shown in broken lines are adopted.
