Definitions

  • the invention relates to a device for closing a package filled with a flow agent, the backing material of paper, cardboard or the like is coated with plastic on at least one surface, with a pair of spreading fingers which can be inserted into the open end of the package and are driven for a spreading movement for laying flat of the upper packaging edge with the folding seam strip and with a pair of welding jaws attached to pivoting levers for sealing the upper folding seam strip and with a drive having guide surfaces.
  • the spreading fingers only carry out a pivoting movement, the free lower ends passing through a larger pivoting arc than the parts of the rod-shaped spreading fingers which are further towards the pivot point.
  • they do not necessarily engage in the right place on the open end of the pack on the upper folding seam strip, namely not exactly where the two obliquely converging embossing lines collide to form the triangular flap of the block base; rather, and disadvantageously on the outermost edge of the upper fold seam strip above it, whereby correct folding cannot be achieved because the tensile and folding forces introduced by the spreading fingers for folding are not along the embossing lines and in particular not along those necessary for the formation of the triangular flap Embossing lines are performed.
  • the object of the invention is therefore to improve the device with the features mentioned above in such a way that in a single operation, in a single cycle, so to speak, a filled package can be folded exactly according to the intended embossing lines and can be welded equally tight.
  • each spreading finger is strip-shaped at its engaging ends with narrow, rounded edges and in the plane of the upper folding seam strip from an initial position in which the two spreading fingers are so close to each other that they are in the open upper folding seam strips can be inserted, is movably driven up to an end position at which the spacing of the spreading fingers is approximately equal to the length of the flat folded seam strip, and that each welding jaw synchronizes with the movement of the spreading fingers around a shaft arranged parallel to the upper folded seam strip and held in a stationary bearing is rotatably driven so that it strips the folded seam strip from the spreading fingers in the end position.
  • the above measures allow the open, embossed packaging end to be folded exactly in a very short work cycle and then the entire sealing seam is completely welded, in particular in a state in which the two triangular flaps lie stretched in one plane.
  • the package which may have, for example, a round or square cross section, closed on one side and filled into the device according to the invention, so that, for. B. - With the package usually standing "below" the later end wall lies while on the opposite side, ie above the bottom of the device is pre-embossed but is open.
  • a block bottom is folded and sealed in the manner described that the sealing seam in the upper folding seam strip closes the filled package in an absolutely sealing manner from one end to the other after the work cycle in question.
  • the length of the welding jaws is greater than that of the upper folding seam strip. It is understood that in this stretched folding seam strip in the area of the block bottom, the two triangular flaps lie in a common plane and are stretched outwards.
  • the measures of the invention result in a short welding time, so that work cycles of the order of 1.5 seconds or less are obtained.
  • Short welding time means high pressure, because time Heat and pressure are the three parameters that ultimately work together and create the weld.
  • an absolutely tight weld seam is achieved according to the invention, which runs from one end of the upper folded seam strip to the other, namely over the two edges at the ends of the folded seam strip.
  • this tight welding is achieved, although at the same time an exact folding is also carried out, from a so-called raw shape of the open package with an oval or square cross-section to the finished folding seam strip in the manner described above.
  • each welding jaw is fastened to two swiveling levers arranged in such a way that the shaft and associated welding jaws are provided on opposite sides of a plane laid by both spreading fingers.
  • a plane defined by the two spreading fingers which, when the packing is inserted, in the final state, i.e. in the case of a welded folding seam strip, is arranged above this. At least the engagement ends of the spreading fingers only move in this plane, as will be explained in more detail later.
  • the long swivel levers can apply high pressures to the welding jaws.
  • the welding jaws can run on such tracks shortly before engagement with the outer sides of the upper folding seam strip that, when the spreading fingers are stationary, when they have reached their end position, they strip the end of the pack, in particular the folding seam strips, from the spreading fingers.
  • the upper end of the pack is brought into the desired final shape, because the respective welding jaw presses on the upper surface of the block base already brought together by the spreading fingers.
  • the upper folding seam strip is zoned down by approximately 8 to 9 mm from the engagement with the spreading fingers.
  • the upper folding seam strip which is a double cardboard strip, is from one edge to the other, i.e. from the beginning to the end, completely free of engaging machine parts, so that immediately afterwards the sealing jaws can perform their function and advantageously with high pressure.
  • the sealing seam within the upper fold seam strip is 2 mm wide, and this seam lies at a distance from the
  • a cam piece is mounted in a stationary plate for driving the expanding finger, a cam roller connected to the expanding finger is movably guided on the cam piece, and the cam roller is displaceably driven by a drive parallel to the plane of movement of the expanding fingers.
  • the cam roller is mounted on an axis running transversely through two roller carrier plates, the roller carrier plates are each fastened to a slide which is freely movable longitudinally on a mandrel and if the mandrel is fastened to a guide which is displaceably indicated on a stationary column. So you just need leadership in a z. B. to move the vertical direction up or down - of course within the framework of predetermined, mechanical limit points - and in this way achieves the movement of the slide in the horizontal direction, with the slide simultaneously moving vertically on its mandrel. This means that complicated routes can be traveled through using simple means.
  • the curve piece has the shape of a curved elongated hole and the curve roller is guided in it.
  • the longitudinal axis which is thought to be centered in the vertical direction by the respective spreading finger, can run essentially perpendicular to a line laid longitudinally in the upper fold seam strip or in the plane of the fold seam strip.
  • the spreading fingers therefore move in the plane to be thought of as laid by the upper fold seam strip (in the vertical direction).
  • the representation of the figures here is a plane lying in the paper plane, in which the longitudinal axes of the spreading fingers then also lie.
  • each spreading finger is angular in cross section with a base part.
  • the respective base part lies in the horizontal plane in the usual construction of the machine, and the front ends of the spreading fingers lie in the vertical plane, as described above.
  • the base part can now be attached to the expansion and welding stations on a drive in such a way that in this way the possibility of doubling the effect of the drive is achieved or, in other words, the possibility is achieved with a single drive arranged in the middle of both To operate welding and folding stations.
  • a swivel axis is arranged on a swivel axle support, about which two swivel levers, each connected to a cam roller, are rotatably provided, the free fingers of which are attached to the free end.
  • the spreading fingers also perform a straight-line sliding movement from the initial position to the engagement of the upper folding seam strips, in which the above-mentioned longitudinal axis in the spreading fingers lies perpendicular to the line in the upper folding seam strip after engagement in the folding seam strips, however, a pivoting of the spreading fingers is carried out, namely about the pivot axis held rotatably by the pivot axis carrier. This measure leads to less effort for the machine drive.
  • each pivot lever is less than 30 °, preferably only about 20 ° from the vertical, then the disadvantages described at the outset in connection with the prior art are eliminated.
  • a circular or swiveling movement is also carried out by the swiveling, the swiveling levers are very long with regard to the part of interest here, namely between the free lower end of the spreading fingers up to the swiveling axis.
  • This length for 1 liter milk packs is e.g. B. more than the height of the pack.
  • the respective spreading finger moves very little from its vertical position into the deflected or swung-out position.
  • the cam control only focuses on a rotary movement, so that the structure of the drive is evidently simpler as a result.
  • the swivel axis support for holding a double station is fork-shaped and has two swivel levers on each side, preferably connected to one another by a tension spring, via the swivel axis.
  • the swivel axle support can be held on one side by a stationary column and fastened in a linearly displaceable manner, but at the opposite end it can be provided with two brackets by the fork, on which the two swivel levers are provided for the two spreading fingers.
  • the fork enables two pairs of swivel levers to be arranged with two pairs of spreading fingers.
  • Each pair of spreading fingers can then be connected via a roller carrier axis on which a cam roller is seated. Since two spreading fingers are required to spread apart the folded seam strip, two roll carrier axes are provided with two spreading fingers arranged at the ends. Preferably, in the middle of these roller carrier axles there is a cam roller each, which roll on opposite sides of the cam piece so that the spreading fingers are deflected in the desired movement path.
  • the curve on the curve piece is designed so that the path of movement of the outer corner of the spreading finger follows the critical point at the end of the upper fold seam strip.
  • the shaft for driving the welding jaw is connected to a sleeve that encompasses it and carries the pivoting lever via a feather key with a clamping device if the feather key and clamping device are arranged in the middle of the longitudinal extension of the shaft and the sleeve and if the clamping device has a clamping reinforcement with tension member clamping a slot in the sleeve.
  • toggle levers are used to drive the welding jaws and to move their pivoting levers, then theoretically infinitely high pressures are achieved between the welding jaws, with the above measures absorbing excessive pressures through a torsional effect between the shaft and the sleeve.
  • the shaft held in the bearing is connected via a feather key, polygon connection or the like to a first drive lever, which in turn is resiliently connected to a second drive lever which is non-positively arranged via a double lever joint.
  • This is the drive for the welding jaws, i.e. a movement which must be initiated in the aforementioned shaft.
  • the frictional connection takes place via a toggle lever or double lever joint to one of the aforementioned second drive levers, from there via the first drive lever and the feather key connection to the shaft.
  • a device for resiliently pretensioning the two drive levers is preferably interposed by a screw connection if, for example, a disk spring assembly is fixed via a tie rod held with a nut and screw.
  • the arrangement of disc springs between the first and the second drive lever also has a favorable effect on the balancing of forces.
  • the resilient bias ensures that even with faulty, for. B. double paper thickness in addition to single paper thickness, the overloading of the welding jaws can be compensated for by the spring unit. Wear in the bearings can also be compensated for, which could disadvantageously otherwise lead to pressure fluctuations and thereby to incorrect sealing work.
  • the springs compensate for this wear or the different paper thicknesses.
  • a lateral displacement rail is provided on each side of the pack inserted between stationary guide plates, approximately below the end position of the spreading fingers in the running direction of the pack.
  • the measures according to the invention thus achieve the folding and welding of a block base in a single, and indeed very short, work cycle, i.e. with a single movement, which in the sense explained above comprises two individual movements synchronized with one another.
  • the pack designated 35 is bulged in FIG. 1 without the displacement rails 40, which will be explained later, and shown retracted into stationary guide plates 11 and 11 '.
  • the package used here for clarification is closed at the bottom on the later "upper end wall", which also has an opening device (not shown), while on the opposite, "upper” side the package in the area of the upper folding seam strip 2 is to be thought of as open.
  • the still undrawn folded seam strip 2 would have a circular shape, oval or egg shape, a shape which is approximately predetermined by the two stationary guide plates 11 and 11 '.
  • cam pieces 14 and 14 'to be explained later two spreading fingers 1 and 1' arranged at a distance from one another have just been inserted into the upper folded seam strip 2 up to its lower edge.
  • S is the critical point at the tip of the triangular lobe.
  • the vertically running lower edge of the respective spreading finger 1, 1 ' has on the outside a corner corresponding to the critical corners S on the pack, which is slightly rounded as shown and from the inside to the left and right folded edge, i.e. comes to rest at the beginning and end of the folding seam strip 2.
  • Dashed lines show two arcuate webs B1, which run through the relevant outer corners of the spreading fingers 1, 1 'or the tips S of the pack, while the upper folded seam strip is stretched and placed on the stationary guide plates 11, 11'. During this movement, the front and rear cardboard strips of the folding seam strip 2, lying in front of or behind the drawing plane, are to be thought of as moving into the latter.

  • the spacing of the spreading fingers 1, 1 'from one another is set in accordance with the specification of a curve piece 14, 14' so that when the spreading fingers move down, their outer corners come close to the critical corners S of the triangular lobes. The state of FIG. 1 has now been reached.
  • the spreading fingers 1, 1 ' move apart, but at the same time downward along the sheets B1, the upper fold seam strip 2 being stretched and the two layers of cardboard being brought together.
  • the spreading fingers then finally reach an end position, which is shown in FIG. 2.
  • the spreading fingers remain in this position, while the welding jaws 3 and 3 ', which in the meantime have moved out of an initial position (not shown), continue to move along the path B3 from the position shown in FIG.

  • the sleeve 28 is provided with a slot at 29. So that there is no play between the movement of the shaft 27 on the one hand and the sleeve 28 on the other hand, for example due to the fact that the feather key 31 deflects during operation due to the oscillating continuous stress, a clamping device is provided, namely a clamping reinforcement 30 which applies to each half of the sleeve 28 is welded on top of both sides of the slot 29.
