Definitions

  • the invention relates to a depositing device for bags provided with glued bottoms, having at least one double belt conveyor which compresses the bottom areas of the bags with its endless press belts.
  • the glued bottoms of sacks must be pressed together immediately after they have been manufactured in order to prevent the bottom folds from erecting while the bonds are loosened and to achieve well-glued bottoms by pressing the bottom areas.
  • double belt conveyors consisting of press belts are provided for sack stacks formed from the sacks just produced, in which the press belts compress the stacks in the region of the bottoms. Since the pressing must be maintained for a sufficiently long time, the double belt conveyors which compress the stack must have a considerable length, which leads to an undesirably long construction of the systems for the production of the bags.
  • the object of the invention is therefore to create a storage device of the type specified above of shorter overall length.
  • this object is achieved in a depositing device of the generic type in that the double belt conveyors, with their superimposed vertical presses and the overlapping sacks between conveying endless press belts, have at least two press cylinders with S-shaped or, in the case of more than two press cylinders with multiple S - partially loop around the conveyor.
  • an S-shaped or multiple S-shaped conveying section which compresses the bottom regions of the overlapping sacks is provided, so that the overall length of the necessary pressing section can be shortened considerably.
  • the pairs of press cylinders are expediently arranged approximately symmetrically to a vertical plane parallel to the press cylinder axes.
  • two press cylinders of the two pairs of press cylinders can be arranged closer and further away from the plane of symmetry.
  • the press belts are expediently arranged only in the area of the two bottoms of the sacks.
  • the sacks are conveyed transversely in the scale, so that the bottom areas are on the outside, ie on the sides of the sack scale.
  • the first cylinder 2 is wrapped for the most part by a drivable pair of belts 6, which is extended to an inlet hand 6 '.
  • the pair of belts 6 acts as a pair of infeed belts 6 '
  • the latter is another drivable pair of tapes 7 assigned, so that the shingled stream arriving in the direction of arrow A passes between the pairs of tapes 6 'and 7.
  • the belt pairs 6 and 11 wrapping around the cylinders 2 and 3 are driven at the same speed, while the inner belt pairs 16 and 23 directly wrapping around the cylinders 4 and 5 are driven at a slightly higher speed than the belt pairs 6 and 11.
  • This measure has the effect that the scale spacing of the scale flow running off from the cylinder 3 is increased in a precisely defined manner as soon as the scale flow enters the belt pairs 16 and 17.
  • the pair of belts 18 consists of two belts, while according to an embodiment according to Figure 3, the outer non-driven belt pair partially wrapping around the cylinder 4 consists of four individual belts 18 'to 18'.
  • the embodiment of Figure 3 has the advantage that the web tensions of the bands 18 'to 18 ⁇ ⁇ can be adjusted individually, depending on the thickness of the ground. This is namely in the area of the tapes 18 ⁇ and 18 ′′′ from four layers, while in the area of the tapes 18 'and 18 options consists of only two layers. In the case of very thin material, this difference is not very serious, so that an embodiment according to FIG. 2 can be selected. However, if a sack is made from a very thick material, the embodiment according to FIG.
  • the additional pair of bands 30 can be provided for all cylinders 2 to 5, or even only for individual cylinders.
  • press belts of higher tension or additional press belts are provided for the outer floor areas, these are subjected to a lower pressure because of the smaller number of layers. It is therefore possible to choose press belts which have such a great elasticity that, despite the different number of layers of the two floor parts, they act on the entire floor area with approximately the same pressure.
