Definitions

  • the invention relates to a device for separating flat sacks lying in a stack, with a sack magazine in which a stack of sacks lies above with the sack magazine in arranged near the bag openings upper suction means and a drivable rolling grille forming an endless loop, consisting of at least two rescues and between the rescues transverse bars, the at least one engagement section for a passage of the upper suction means and at least forms a support section for resting a sack, the rolling grille enclosing the sack magazine.
  • EP 0 380 905 A1 describes a device of the type mentioned at the beginning Known at the top suction means in the area of Bag bottom are provided and after lifting a bag Rolling grille from the bottom part towards the bag opening drives in. By means of the rolling grille, the sack is then turned into one Move the bag opening unit by about one bag length. Installation space for a marking device seems to be present here; the Handling the isolated sack until it is put on one Filling spout is however complicated and requires a complex one Contraption.
  • the invention is based on the object Device for separating bags that are simple is built and works reliably and at complementary means of signing individual sacks unhindered can be added.
  • a sack with the upper suction means in the area of its bag opening by a the engaging portions of the rolling grille are raised therethrough and through the upper and lower suction means on both sides be caught and held securely.
  • Essential for this is the possibility of movement of the lower suction means between the isolated sack and the stack of sacks.
  • the swivel lower suction means in the path previously from the upper Suction devices for gripping and lifting a sack in the area has been passed through twice during its opening. For later When opening the isolated sack, the top and the lower suction means with their suction openings with intermediate ones Sack opposite.
  • the sack If the sack is opened sufficiently, it can be placed on the sack support lying open sack with suitable spreading and attachments spread out and attached to a filler neck become.
  • Suitable suction and gripper means which also essentially can be used here are in the 196 50 653.0-27 described. Suitable means for spreading and attaching the occasional sacks on a sack filler neck are in the 196 04 718.8-27. To the extent permitted, the content of this Applications referenced, their disclosure content here should be included.
  • the resulting length of the rolling grille is preferably two to three contact areas, each with intervening engagement areas provided on the rolling grille.
  • the sack After attaching an isolated sack, the sack remains unchanged Position of the rolling grille with a next sack the upper suction means at its opening end and through the engagement section located under the upper suction means pulled through. Then the lower suction means moved against the top. Then the rolling grille moved by one position, again with a support section between the sack to be separated and the sack stack pushes until the entire sack on the at least one support section of the rolling grille.
  • the rolling grille in Area of the suction means forms an inclined ramp to which a horizontal support plane in the running direction of the rolling grille connects.
  • the degree of lifting necessary of the opening end of the sack to be separated be, since this is from the inside of the the loop formed loop comes out before it over the level of the contact surface is raised.
  • the roller grille can move to be placed between those picked up at the opening end and sack held in from both sides and the stack of sacks retracted to become.
  • Both the upper and lower suction cups medium lead their movements through one in the oblique area Ramp lying engagement section of the rolling grille through out; the rolling grille can only be set in motion, when the upper and lower engagement means in an upper Position are.
  • the loop formed by the rolling grille essentially modified rectangle by the inclined ramp.
  • the rolling grille can be closely adapted to the sack magazine, without significantly increasing the size of the device.
  • the length of the at least one Engagement section corresponds at least to the length of the ramp and that the length of the at least one support section of the rolling grille at least the length of the guide rails Support level corresponds.
  • the rolling grille preferably comprises three engagement sections and three support sections.
  • the preferred configuration of the upper suction means is that these are movable in a vertical guide and in the area retractable ramp into the loop of the rolling grille are. By designing the movement of the top Suction means can the engagement sections in the rolling grille relative be kept small.
  • the lower suction means that these are partially below the sloping ramp are arranged and by the at least one engagement section of the rolling grille through to just above the inclined ramp can be moved.
  • the lower suction means are used to securely hold the sack when moving the Rolling grille when separating to open the already separated Sacks needed.
  • the arrangement is convenient to the Location of the engagement section of the rolling grille in the area of adjusted sloping ramp.
  • the lower suction means are preferably pivoted about a horizontal axis.
  • the upper and lower suction means can separate the sack open symmetrically to its median plane. Sacks of different Length and width can be handled without any adjustment measures become.
  • Figure 1 is in a machine frame shown only in dashed lines 11 shows a sack magazine 12 in which a stack of sacks lying horizontally on top of each other with the sack opening behind can be inserted facing left.
  • a column structure 13 is shown in which various handling devices for the bags are stored.
  • the sack magazine 12 is surrounded by a rolling grille 14, which is an endless closed Loop forms over five sets of pulleys 15-19 runs.

  • the rolling grille 14 includes chains 22 and bars 24 connecting them Deflection rollers tension in the side view in the direction of the bars seen essentially a rectangle, however by the arrangement of the pulleys 15, 16 an inclined ramp 23 is generated at the top left corner.
  • the length of the engagement sections 20 corresponds approximately to the distance between the deflection rollers 15, 16 from each other, i.e. H. the length of the ramp 23.
  • the length of the Support sections 21 correspond essentially to the distance between the pulleys 16 and 17. Between these is a Pair of support rails 25, the support section lying thereon 21 stably supported. Above these support rails 25 is space for arranging a marking device for isolated Keep bags free.
