  • the Conveyor belt 57 is then 61 in one of the two directions driven and thereby the stack 7 of the device 1st promoted away.
  • the carriage 20 begins in the opposite direction 24 to to move back to the stacking position upon reaching it the limit 15 in turn begins upwards in the shaft position to pan.
  • the layers 6 with continuous Speed continuously on the auxiliary support 41, 54 promoted.
  • the auxiliary pad 41 begins to withdraw first, so that the stack layers 6 at the limit 16 first and last at the limit 15 under their weight the edition 8 decrease.
  • the finger becomes 54 swung up again, the associated marginal zones the layer 6 under their curvature deformation over the free end of the finger 54 slide down.
  • the Auxiliary pad 45, 54 so narrow that the stack layers 6 with their edge zones directed against the boundaries 17, 18 hang at an acute angle downwards from level 46, whereby the trouble-free sinking to the pad 8 facilitates becomes.

  • the auxiliary device can now 40 again in the described manner in its catch position be convicted and this time it can be the other Limit 16 are lowered so that the limit 15 as 5 the stack 7 in the direction 24 on the Conveyor 5 transferred, the individual processes the same as be controlled previously described using the conveyor 4 can.
  • the limits 15, 16 are then in opposite directions Direction 25 back into the stack position according to Fig. 7 transfers, after which the limit 16 in the shaft position raised, the device 40 brought into the rest position and the stacking layers 6 are placed on the support 8 again.
  • the stack 7 always remains non-contact. All movements described are positively controlled on each other by said control means Voted.
  • the movements are very simple and can be the same regardless of the formats of the stack layers 6.
  • the bow catcher 50 or the shaft 51 is expediently rectangular infinitely adjustable across levels 10 to 13, 46, to different heights 7 without changing the Stack the height of the table 8 or the conveyor 4, 5 can.
  • the conveyor 5 which, as in Fig. 1 of the conveyor 4, can also be provided alone with Distance below the belts 31, 32 of the conveyor 3, which diagonally to the deflections 36 from a lower level upwards and then only continuously up to the mouth Direction 39 promotes.
  • the conveyor 5 is therefore in side view at the protruding angle of the at the deflections 36 adjoining, at an angle to each other Conveying sections of the conveyor 3.
  • the table 8 can also be used the perforation described with the support 57 to 59 provided and connected to a compressed air source in order to minimize its sliding friction when moving the stack 7.
  • the conveyors in particular their conveyor belts 57, in the longitudinal direction contiguous, separate and independent drivable individual tapes are formed, which e.g. with their ends facing each other in the area of a or more of the stations 2 or the levels 48 or the Close boundaries 18 so that from the shafts 14 simultaneously acquired stacks 7 in simultaneously opposite directions 61 are transported away can.
  • Adjacent stacks reach the conveyor 4 or 5 with a distance from each other, the small thickness of the consistently flat sheet metal walls 18, so that all Stack 7 from all shafts 14 with this distance as Column are transported away with the conveyor 4 or 5 can.
