Definitions

  • the invention relates to a device for laying flat objects continuously conveyed in the transverse position, preferably tube sections or sacks made of paper, in Z-folds.
  • Paper sacks are usually stacked, bundled and placed on pallets for transporting the stacks.
  • the size of the pallets must correspond to the length and width of the flat-lying sacks, so that they take up an unnecessarily large amount of storage space.
  • the height of the stack of paper bags is determined by the height of the cross bottoms lying on top of each other, because in contrast to the middle areas of the bags, in the bottom areas there are many layers of bags one above the other. In the case of stacks made of cross-bottom bags, opposite sides of the stack are high, while the middle stack area collapses, which leads to unsightly stack shapes and a waste of space.
  • the starting point of the invention is the finding that more compact, less storage space-requiring, more stable and more elegant stacks of cross-bottom bags can be formed when the area of the flat-lying bags between the end-side cross bottoms is folded in a Z-shape, so that the double-cross-folded bags also in have a height corresponding to the floor areas in their central area.
  • the object of the invention is therefore to provide a device for Z-shaped folding, in particular of cross-bottom bags, so that they can be stacked into compact, straight-edged stacks.
  • this object is achieved in that pairs of interacting creasing wheels are arranged on both sides of the conveying plane of an infeed double belt conveyor, each consisting of individual double conveyor belts arranged in the region of the ends of the objects, on shafts parallel to its roller shafts, the transverse spacings of which correspond to the desired distance between the folded edges of the Z-folds that one of the individual belts is followed by a single double conveyor belt which runs obliquely on the other and which is continued by a straight double conveyor belt which corresponds to the shortening of the objects by the Z-fold in relation to the inlet double belt conveyor is approximated to the other single double conveyor belt that the end pulleys of the upper or lower belt of the inclined double conveyor belt with the adjacent pulleys of the straight conveyor belts can be lifted alternately from the pulleys of the associated conveyor belt so that each passing object is clamped only by a pair of rollers is, and that essentially over the length of the inclined double conveyor belt above and below the conveyor level, a folding rod is
  • the device according to the invention makes it possible to fold the middle regions of K reuzboden sacks between the end bottoms in a Z-shape during the passage of the sacks during the passage through the device, so that they are shortened by almost half their length and become correspondingly smaller have stable and compact stacks piled up.
  • the two folding rods run towards each other in such a way that they each execute about half a helical turn over their length relative to one another.
  • the device according to the invention can also be used for folding hose sections, for example when it comes to shortening them with different lengths in such a way that the devices forming the bases can always be arranged at the same distance from one another.
  • the pre-grooved sacks or objects are in the process of being folded by the folding bars between the straight double conveyor belt and clamped the inclined double conveyor belt, the course of the inclined double conveyor belt being chosen such that the shortening of the bags or objects is taken into account during the Z-fold formation.
  • the rollers of the double conveyor belts can be lifted in opposite directions in the transfer areas.
  • the roles of the inclined double conveyor belt and the subsequent double conveyor belts can be changed in their distance from the other straight double conveyor belt.
  • the deflection rollers 9, 9 'of the short double conveyor belt 7 of the infeed belt conveyor are mounted in bearing blocks 10, 10' which are guided transversely displaceably on guide rods 11, 11 'fastened in the side walls 1, 2 and - by shafts 13 mounted in the side walls 1, 2 , 13 'are adjustable in the transverse direction with sections provided with threads 12.
  • the sections of the shafts 13, 13 'provided with the threads 12 are screwed into corresponding parts of the bearing blocks 10, 10' provided with internal threads.
  • the bearing blocks 14, 14 'for the driven rollers 15, 15' of the double conveyor belt 7 and the rollers 16, 16 'for the inclined double conveyor belt 6 are transversely displaceable on guide rods 17, 17' fastened in the side walls 1, 2 and with threads provided shafts 18, 18 'adjustable in the transverse direction.
  • the respective bearings can be pivoted about vertical pins 19, so that changes in angle which occur during adjustment can be compensated for in an informal manner.
  • the bearing blocks 20, 20 'for the drive rollers 21, 21' of the inclined double conveyor belt 6 and for the drive rollers 22, 22 'of the double conveyor belt 8 are correspondingly displaceable in a corresponding manner on guide rods 23, 23' and via threaded shafts 24, 24 'adjustable in the transverse direction.
  • this is additionally displaceably guided in a slot 26 of the bearing block 20'.
  • deflection rollers 27, 27 'of the double conveyor belt 8 are supported with their bearings on pedestals, which can be adjusted in the transverse direction via guide rods and threaded shafts.
  • the shafts 18 'and 24' provided with the threads are provided with handwheels 28, 29 on their shaft ends passing through the side walls 2, the shafts 18, 10 also being rotated in the same direction and 10 'on the one hand and the corresponding adjusting shafts 24, 24' and 30, 30 'are wedged onto the chain edge shafts over which endless chains 31 run.
  • All conveyor belts are covered by cross-sectionally U-shaped housings, the lower housings 32 of the inclined double conveyor belt 6 being connected to the bearings for the deflection and drive rollers and carrying the upper cover housings 34 by means of carrying brackets 33 fastened to them.
  • the ends 35, 36 of the upper cover housing are hinged to the central part of the cover housing 34, so that the bearings of the upper deflection and drive rollers 16, 21 can be raised with the pivotable ends 35, 36 of the cover housing 34.
  • the bearings of the deflection rollers 15, 16 and the drive rollers 21, 22 are articulated via coupling rods with rocker-like supports 37, 38, which are pivotably mounted in the bearing blocks 14, 20 and can be pivoted for alternately lifting and lowering the rollers via pressure medium piston cylinder units 39, 40 .
  • the driven rollers 15, 21, 22 are connected with their drives via cardan shafts with plug connections for length compensation.
  • folding rods 45, 46 are fastened to support rods in the machine frame, which are wound around one another in the form of half a helix and, during the passage, place the sack 47 around the pre-grooved folding lines 48, 49 in a Z fold , as can be seen from FIGS. 4 and 5.
  • a straight folding sword could also be provided, around which the other folding bar 45 places the sack 47 as it passes through in a Z-shaped fold.
  • Flange-shaped extensions 5 0 , 51, 52 are fastened to the lower housing-like covers, which serve to support the continuous sack 47.
