Definitions

  • the invention relates to a device for separating stacks from flat-lying Sacks with bottoms folded into the sack level.
  • the object of the invention is therefore a device of the type specified to create, with which the stacks formed immediately after the sack production separate from flat-lying sacks and combine them into units ready for dispatch to let.
  • this object is achieved by a device for separating Stacking of flat-lying sacks with the floors folded into the sack level with the Features of claim 1 solved.
  • the conveyor advantageously consists of at least two parallel to one another revolving endless conveyor belts running at different speeds are drivable.
  • the speeds of each are Conveyor belts are coordinated so that the Side edges of the bags that are thrown onto these in an inclined position parallel to the conveying direction be aligned.
  • Rotary feeders for separating sack stacks, as for example for the separation of the hose section packages at Sack production for placing the isolated hose sections on the floor layer be used.
  • Rotary feeders are relatively expensive, so farms that have stacked paper bags fill with bulk goods, the purchase of which shy away.
  • Rotary feeder are not only associated with high acquisition costs, they are also only suitable bad for separating sack stacks because the bottoms of the sacks in the sack stacks tend to stand up more or less so that a safe suction of the individual bags is not guaranteed with certainty by the rotating suction rolls and there is congestion and consequent business interruptions can come.
  • the device according to the invention consists of the combination of one in the Pre-published DE-A-195 29 935 described separation device with a known device for producing scale tape rolls, as they has been described for example in DE-A-25 44 135 and EP-B-00 54 735.
  • the separation device used according to the invention ensures the separation of the individual sacks also from a loose stack of sacks and even if the individual sacks are not yet at the time of stacking completely set adhesive should be glued together.
  • the separating device 1 consists of a machine frame with the side parts 2, 3, on the inside of them via holding pieces 4, 5 guideways consisting of profiles 6, 7 for rollers 8 rotating on these.
  • the two Guideways 6, 7 arranged parallel to one another each consist of upper ones and lower parallel sections, which are approximately semicircular Sections are interconnected.
  • the on the guideways 6, 7 guided rollers 8 arranged parallel to one another at equal intervals are attached at their ends to endless chains or traction elements, which are not shown in Guides run and are driven by drives, not shown.
  • the rollers 8 consist of cylindrical tube pieces that are freely rotatable on axes are stored, the axle journals 10 on which they move over the guideways 6, 7 Chains or traction elements are attached.
  • rollers form a moving roller grate, above a cassette 12 forming a stacking magazine is held in the side parts 2, 3 is, which is used to hold stacked paper bags 13, which after their separation brought into a shingled formation and then closed Scale tape rolls are wound up.
  • the cassette 12 has four side walls, at least one side wall 14 in the direction of the double arrow through a manually operated spindle drive to different sack formats is adjustable. The bottom of the stacking cassette 12 is through the upper strand 11 of the migrating roller grate.
  • the front deflection rollers 20 of the two suction belt conveyors running in parallel next to one another 17, 18 are mounted on brackets 21 which are attached to the side frame 2 are.
  • the endless conveyor belts 17, 18 pass through a rectangular window-like Cutout 22 of the side frame and run over the delivery ends forming driven pulleys 23, 24, which in a manner not shown in Machine frame are stored.
  • the driven deflection rollers 23, 24 are driven by controlled geared motors at different speeds.
  • the moving roller grate moves in the direction of arrow A under the stacking cassette 12 through.
  • Plate-shaped, opposite side walls of the Stack cassette-bearing plates 30, 31 are on their underside with the friction increasing Provide pads 32 to which the lateral end portions of the freely rotatable, Roll sleeves consisting of pipe sections of the rolls 8 during their passage be pressed under the cassette so that it rotates with which they can be seen in FIG. 3 in each case on the Support the lowest sack stacked in the cassette 12.
  • the type of peeling of the bottom sack from the stacking cassette and the The drive of the liftable and lowerable suction cup basically corresponds to the illustration and description in DE-27 32 591 C2, to which reference is made for a more detailed description becomes.
  • the suction cups 35 are also described in DE-27 32 591 C2 Way connected to suction air sources, which the vacuum cleaner 35 with in time Supply suction air.
  • a computer which has sensors the position of the hose sections thrown onto the suction belt conveyors 17, 18 is detected and the geared motors in such a way according to a possibly found skew controls that a delay due to the different speeds of the suction belt conveyor is balanced.
  • the speed of the Suction belt conveyors can also be made by hand after visual assessment. Because of the type of arrangement of the geared motors and their control is closer Illustration referred to DE-A-195 39 935.
  • the sacks placed on top of one another on the conveyor belts 17, 18 are stacked Then run from these in scale formation on the subsequent conveyor belt 40, which is arranged fixed to the frame in a manner not shown.
  • the crowd of endless Conveyor belts of the conveyor belt 40 runs over the front deflection roller 41 driven by a gear motor 42 through endless belts or chains 43.
  • Drawn from two rollers 45 placed side by side in racks and parallel Retaining straps 46 extending to one another are guided via guide devices 47 and then run over the rear guide roller 40 under the scaled one above the other Bags 13 on the second conveyor belt 40.
  • the second conveyor belt 40 there is a swiveling one Frame 48 held winding core 49 on which the overlapping the scaled Bags 13 are wound into a scale roll 50.
  • the winding core 49 or the forming scale roll 50 is with the necessary pressure against those to be wound up, scaled one above the other Sacks pressed.
  • This pressure is from a controlled pressure medium piston-cylinder unit 41 generated, the cylinder on the frame and their Piston rod is hinged to the swivel frame 48.
  • the pressure medium piston cylinder unit 51 pivots according to the growing diameter the scale belt roll 50 the swivel frame 48 to the right.
  • the holding tapes 46 are on the winding core 49 at the beginning of the winding process attached so that they overlap when winding the scales Sacks to the scale belt roll 50 holding from the outside over the scaled Place bags 13 on top of each other.
  • the straps are cut and their ends on the scale tape roll set so that the scale tape roll with the winding core from the frame 48th removed and a new core for winding the next roll of scale tape can be inserted.
