Definitions

  • each spreading finger is strip-shaped at its engagement ends with narrow, rounded edges, its longitudinal axis is perpendicular to the upper fold seam strip at least during its movement in the area of the initial position and via a curve in a plane above the fold seam strip is movably driven and that each welding jaw with the movement of the spreading fingers synchronized about a shaft arranged parallel to the upper folding seam strip and held in a stationary bearing, is rotatably driven so that it strips the folding seam strip from the spreading fingers in the end position.
  • the sealing seam within the upper folded seam strip is 2 mm wide, and this seam lies at a distance from the lower edge of the folded seam strip so that the critical point, ie the corner at the top of the triangular flap, would create a connection between the inside of the pack and the outside in the event of an injury.
  • the lower edge of the spreading finger runs horizontally and is rounded but narrow like a blunt knife, the engagement between the relevant outer corner of the spreading finger and the tip of the triangular flap can be ensured and can be maintained during the spreading movement and in general with all folding movements. It is expedient if the spreading fingers are not rotated, for example, but are guided through a suitable curve in one plane.
  • 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 the engagement In the folding seam strips, however, the spreading fingers are pivoted, namely about the pivot axis which is rotatably supported by the pivot axis carrier. This measure leads to less effort for the machine drive.
  • the block bottom is folded and closed by the device according to the invention in such a way that the round or slightly square preformed and open package at the upper end in cross section between the two spaced-apart stationary guide plates 11, 11 'promotes a g is, the upper edge with the open folding seam strip 2 possibly extends a little.
  • the distance between the spreading fingers 1, 1 'from one another is set in accordance with the specification of a curve 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 station can be seen well from FIGS. 4 and 5.
  • the stationary plate 15 in which two arcuate elongated holes are provided as curves 14, 14 'as a pair so that the above one their ends leaning towards each other.
  • a cam roller 12, 12 ' can move in this curve 14, 14' and is mounted on an axis 16 which in turn extends through two roller carrier plates 18, 18 '(FIG. 3).
  • the roller carrier plates are not stationary, but move together with the axis 16 and the cam roller 12 (or 16 'and 12').
  • the welding station can be expediently explained with reference to FIGS. 3 to 6.
  • two torsion shafts 27, 27 ' arranged parallel to the plane of movement of the spreading fingers 1, 1', namely on each side of the same, are mounted at the same distance therefrom and rotatably provided in bearings, one of which is designated 36 and at the top right in FIG. 5 is shown.
  • the shaft 27, 27 ' is located in a sleeve 28.
  • the connection between the shaft 27, 27' and the sleeve 28, 28 ' can be seen in FIG. It is a feather key 31.
  • the connection can also be provided by a splined groove or a polygonal fit.
  • the key 31 is firmly screwed into the shaft 27, 27 '.
  • the sleeve 28 (and the other side, provided with the subscription verse) has a correspondingly suitable slot, in which the feather key 31 is inserted from the outside through the sleeve 28 into the shaft 27 and screwed into it. This connection represents a rotation lock between the shaft 27 and the sleeve 28.
  • 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. The two clamping reinforcements 30 can be clamped against one another by a screw 37. So that the slot 29 is compressed in the sleeve 28.
  • the drive for the movement of the shafts takes place via a hydraulic cylinder 24, which is put into operation when the guide 10 is lowered by mechanical contact of the lower end 10 ′ of the guide 10 with a proximity switch 23.
  • the proximity switch 23 (FIG. 4) is arranged with respect to the lower end 10 ′ of the guide 10 in such a way that the movement schematically explained with reference to FIGS. 1 and 2 can take place.
  • FIGS. 7 to 9 Another embodiment of the invention is illustrated and explained with reference to FIGS. 7 to 9 with regard to the curve piece and the control or drive of the spreading fingers 1, 1 '.
  • the vertical stationary column 112 (which corresponds to the pull rod 22 and the arm 38 in the first embodiment).
  • the horizontally extending swivel axis carrier 110 is attached (which in turn corresponds approximately to the mandrel 7 and the guide 10 in the first-mentioned embodiment).
  • the left end of the swivel axis Carrier 110 shows the pivot axis 111 in FIG. 7, about which two pivot levers 115, 115 ', each connected to a cam roller 12, 12', are rotatably provided.
  • the swivel levers 115 (on the right side of the double station) or 115 "(on the left side of the double station) are shown in their particular configuration according to FIG. 8.
  • the knife-like spreading fingers 1, 1" are in this construction in FIG 8 inserted and shown screwed. While only the front and left spreading fingers of both pairs of spreading fingers can be seen in FIG. 8 (1, 1 "), both spreading fingers 1 and ' 1' of a pair can be seen in FIG. 7.
  • Each spreading finger is at its engagement ends, which are shown in the figures below are shown, ie opposite and shortly before the engagement in the upper folding seam strips 2 of the pack 35, strip-shaped with narrow edges, and the corners E, E 'of the respective outer rounded corner of this spreading finger, which are connected to the in FIG Figure 1 explains the critical point S of the folding seam strip 2 from the inside.
  • Figure 7 also shows the movement curve of the corner E or E 'corresponding to the path B1 in Figure 1. This curve illustrates the movement of the spreading fingers 1, 1' from the figure 1 in FIG Figure 7 with solid lines position, the starting position, in the end position, which is shown in dashed lines in Figure 7 and corresponds approximately to that of Fig. 1.
  • a bracket 108 is shown as a fastening of the curve 107, which runs horizontally approximately parallel to the pivot axis bracket 110. In the embodiment to be described first, it approximately corresponds to the carrier 13.
