  • adjustable stop 65 are coupled together. For better clarity, in each case a small distance to the centering fingers 51 and 52 is shown in FIG. 15 on both sides of the bag stack 2, which may be present during an actual centering of a bag stack 3, but need not be present.
  • FIG. 16 shows a highly schematic view of the processing device 1 with the centering device 50 and the plate 53 of FIG
  • the centering device 50 additionally has a drive unit 75 with which the centering unit 51 can be moved separately.
  • an adjustable stop 65 is provided, which is adjusted to the bag width 48.
  • the adjustable stop 65 is provided movably via a drive unit 76.
  • the bag width 48 can be adjusted via the path detection device 74, computer-controlled. As a result, the bag width 48 can be adjusted automatically when processing bags of different widths.
  • the centering unit 51 is positioned directly on the stop 65 via the drive unit 75. This means that the centering unit 51 is transferred directly to its end position, which corresponds to the position 63 from the preceding example according to FIG.
  • the centering unit 52 remains in the first position 61 below the plate 53rd
  • Piston rod 58 of the cylinder 56 extended.
  • the belt 54 is transported directly on and the centering unit 52 pivots about the guide roller 60 and through the groove 45 in the plate 53 upwards.
  • the centering unit 52 moves on further extension of the cylinder 58 to the first centering unit 51 until the third position 63 and thus the end position is reached.
  • FIG. 17 shows the intermediate position of the centering unit 52 in the second position 62.
  • the invention provides an advantageous processing Device available, with a reliable centering and / or separation of the bags is made possible.
  • the centering device according to FIGS. 13-15 enables a central centering and reliable positioning of a
  • Sack stack 2 wherein the centering units 51 and 52 from both sides 46 and 47 approach to the stack of sacks 2.
  • the stack of sacks is positioned at an end stop, which here through the
  • Centering units 51 is formed. For further centering, the centering units 52 approach the sack stack 2 from the other side 47.
  • the open sacks are processed by the centering units 51 and 52 in FIG.
  • the invention provides an advantageous processing device and an advantageous method, with which open sacks of a sack stack can be separated reliably and effectively.
  • the space required and the space required are small.
  • the performance can be significantly increased over the prior art, so that both
  • markings and other applications can advantageously be applied to the opening bag.
  • the control of the processing device 1 can be carried out via a control device, not shown here, which has one or more light barriers or other sensors to ensure defined positioning during the entire operation.

Abstract

L'invention concerne un dispositif de traitement et un procédé permettant de traiter une pile de sacs comprenant une pluralité de sacs ouverts, la pile de sacs pouvant être agencée dans une position initiale sur un dispositif de dépôt, les sacs ouverts de la pile de sacs présentant une étendue en longueur et une extrémité de remplissage ouverte. Selon l'invention, un dispositif de marquage et un dispositif de transport des sacs sont adaptés pour saisir le sac ouvert du sommet de la pile dans la position initiale et le mettre dans une position de réception ne portant que partiellement sur la pile de sacs, et pour munir les sacs ouverts dans la position de réception d'au moins un marquage.
