Definitions
- the invention is based on a tubular bag machine according to the preamble of claim 1.
- a packaging material web is conveyed over a hollow shaped tube and formed into a tube.
- the cross section of the molded tube goes in the direction of the
- Hose continuously from a circular cross section into a rectangular cross section at the outlet end, on the underside of which the hose end section is folded by means of a folding device to form a folded stand or block bottom with V-shaped side folds.
- the disadvantage here is that the tube is compressed to different degrees in the longitudinal direction during its transition from the circular cross section to the rectangular cross section due to the unevenly long surface lines of the molded tube.
- elastic packaging materials and packaging materials that have a high coefficient of friction, such as. Paper
- wave and wrinkle formation which can make film transport difficult.
- the appearance and tightness of the bag packs made from the tube can even be impaired. It is therefore desirable to have a tubular bag machine with which packaging materials with high coefficients of friction and packaging materials which tend to form waves and folds, such as paper or the like, can also be processed wrinkle-free into bag packages.
- the tubular bag machine according to the invention with the characterizing features of claim 1 has the advantage that the length differences of the surface lines of the Form tube minimized and the corrugation and wrinkling of the packaging material is thus reduced.
- the intermediate cross section is square, in which case the molded tube can be produced particularly easily.
- the lower regions of the side walls of the molded tube can be provided with cutouts, or the full-surface side walls can be replaced by appropriately shaped rods.
- FIG. 1 shows a tubular bag machine simplified in front view
- FIG. 2 shows a simplified longitudinal view of the lower part of a molded tube
- FIG. 3 shows a side view of the molded tube according to FIG. 2
- FIG. 3 shows a perspective view of the molded tube according to FIG. 3 in schematic form
- 5 shows a plan view of the lower part of the molded tube.
- a tubular bag machine 10 has a shaped shoulder 11 and a round, essentially hollow cylindrical shaped tube 12 and a longitudinal seam sealing device 13, with which a packaging material web 14 is formed into a tube 16 in a known manner.
- a draw-off device in the form of two, for example, vacuum-assisted conveyor belts 18 for the hose 16 is assigned on both sides of the shaped tube 12 at the level of the longitudinal seam sealing device 13.
- a filling tube 19 for the filling material extends concentrically in the shaped tube 12.
- a combined transverse seam sealing and separating device 21 for sealing and separating bag packs 22 from the tube 16 is located below the shaped tube 12.
- a folding device 25 with side folders 26 for folding V-shaped side folds in the bottom and optionally in the top closure of the bag pack 22 and for forming a stand or block bottom is arranged above and below the transverse and sealing device 21.
- a lower part 27 with two sections 28, 29 adjoins the upper part of the molded tube 12.
- the first section 28 has a circular inlet cross section 31, which merges into a square intermediate cross section 32 at a distance m.
- the second section 29 finally merges from the square intermediate cross section 32 into a desired rectangular outlet cross section 33, which at the same time forms the outlet end of the shaped tube 12.
- the outlet cross section 33 is located at a distance M from the inlet cross section 31.
- All cross sections 31, 32, 33 of the molded tube 12 are arranged parallel to one another and their focal points Sk, Sq and Sr lie on the axis of symmetry 34 of the molded tube 12.
- the circumferences of the cross sections 31, 32 and 33 are also all identical.
- the first section 28 of the lower part 27 of the molded tube 12 consists for example of eight interconnected sheet metal parts 36 to 43. This is followed by a triangular flat part 36 to 39 each with a curved part 40 to 43 and vice versa, so that the transition is as continuous as possible from the circular inlet cross section 31 to the square one
- the second section 29 is composed of four trapezoidal parts 44 to 47, whereby a continuous transition from the square intermediate cross section 32 to the rectangular outlet cross section 33 is also achieved.
- the two sections 28, 29 produced in this way are welded to one another in the transverse direction, for example.
- care must be taken to ensure that there are no sharp edges or corners that could damage the hose 16 during the transition from one cross-section to the other.
- the two sections 28, 29 can also be produced, for example, by unwinding the two sections 28, 29. If the sections 28, 29 consist of a material other than sheet metal, for example of plastic, it is also conceivable to produce the sections 28, 29 from a single part.
- the square intermediate cross-section 32 has the smallest possible horizontal deviation between the round inlet cross-section 31 and the rectangular outlet cross-section 33.
- the surface lines lb-lc to 8b-8c between the intermediate cross section 32 and the rectangular outlet cross section 33 are always of the same length.
- an angle ⁇ results in the jacket, which becomes greater the smaller the distance between the intermediate cross-section 32 and the outlet cross-section 33. If the angle ⁇ is too large, however, the frictional resistance of the packaging material is increased. It is therefore necessary to find a compromise with regard to the length of the sections 28, 29 such that, for a given total length M, the distance between the
- the optimal distance m is larger or smaller than the distance m by a certain amount, so that the packaging material along the surface lines la-lb-lc to 4a-4b-4c is additionally also somewhat stretched "however requires a certain elastic packaging material.
- sections 28, 29, in particular on the trapezoidal parts 44 to 47 which prevent clogging of the product flow cross section.
- parts 36 to 47 which are preferably made of sheet metal
- sections 28, 29 which are appropriately curved and which are arranged at least in the region of the generatrices la-lb-lc to 8a-8b-8c and are preferably round and preferably one have a smooth surface.
- Embodiments of the invention are not limited to one
- Shaped tube 12 limited, which allows a transition from a round to a rectangular cross section. In the same way, a transition from a rounded rectangular cross section to a sharp rectangular cross section is possible by means of an intermediate cross section with a different length / width ratio. It is essential for the invention that the different lengths of the jacket lines on the circumference of the packaging material are minimized by an intermediate cross-section during the transition from one cross-section to the other.
