Frictional forces in the transport plane 16 transmit the movement of the endless belt 26 to the belt 17, the carriage 11 waiting in the first end position 9 being accelerated in the direction 36 towards the second end position 10.
  • the belts 17 and 26 convey the sheet 3 detected in the input plane 27 in the direction 36 at twice the speed of the carriage 11.

Each suction cup 43 is seated in a radial bore 44 in the suction roller 42 and, with its edge on the suction surface, projects only a few tenths of a millimeter above the surface of the suction roller 42. The air in the suction cup 43 can be drawn off through the bore 44 or through the bore 44 by means of ventilation be fed. If a plurality of suction rolls 42 are lined up on the same roll axis 41, the suction cups 43 are arranged on the surface line common to the suction rolls 42.

  • the first sensor 37 (FIG. 1) releases the suction of the air in the suction line 45 and in the suction cups 43 when the carriage 11 begins to travel an intake section A in the direction 36.
  • the suction roller 42 is aligned with the stack 1 such that after the front edge of the cover sheet 39 has been rolled over, the suction cups 43 always lie flat on the front end of the cover sheet 39 with their edges on the suction surface. During suction, a negative pressure is created in the suction cups 43, as a result of which the front end of the cover sheet 39 is lifted from the stack 1 by the external air pressure and nestled against the suction roller 42.
  • the suction roller 42 continues to rotate clockwise and, as can be seen from FIG. 4b, rolls the front end of the cover sheet 39 - nestled around the suction roller 42 and the belt 17 - from the stack 1 and introduces the rolled front end of the cover sheet 39 between the belt 17 and the endless belt 26.

  • the sensor signal of the first sensor 32 (FIG. 1) ends this output cycle.
  • the device described has the advantage that the sheet 3 is guided between the belts 17 and 26 in a frictional manner when it is received and output in the transport system 29, and any sliding movement which can damage the sheets 3 or the device is blocked is avoided.
  • the advantage of the rolling movement of the firmly guided sheet 3 on the stack 1 lies in the trouble-free processing of the sheets 3 with very different characteristics, as is observed, for example, between new and widely used bank notes.
  • the control device 34 has a counter 49, the level of which corresponds to the number of sheets 3 stacked on the plate 2 in the stack 1. At the beginning of each external triggered acceptance cycle ', the control device 34 reads the status of the counter 49 and determines in an arithmetic unit 34' whether the number of sheets 3, 39 on the stack 1 is an even number or an odd number.

  • Successive layers are offset from one another, the even-numbered leaves 3, 39 being a predetermined first offset distance L from the front boundary 50 and the odd-numbered leaves by a predetermined second offset distance K from the rear boundary 51. If all sheets 3, 39 are of equal length, the two offset sections L and K are of equal size.
  • the position of the cover sheet 39 deposited on the stack 1 depends only on the location of the carriage 11 on the rail 8, which the carriage 11 at the moment the cover sheet is recorded as the current one 39 serving sheet 3 by the belts 17 and 26 in the entrance plane 27 ( Figure 1) and 28 ( Figure 1).

If the drive 35 has the stepper motor 35 ′, the instantaneous position of the carriage 11 on the rail 8 can be determined for the control device 34 from the number of steps. After complete rolling of the new cover sheet 39 in its predetermined position on the stack 1, the control device 34 increases the level of the counter 49 by 1 and completes the acceptance cycle.
  • the direction of travel of the carriage 11 during the issuance of the cover sheet 39 is determined in a predetermined manner from the status of the counter 49 in the control device 34, the direction of travel of the carriage 11 depending on the assignment selected when accepting, which determines which sheets 3, 39 are stored with the offset distance L.
  • the cover sheet 39 is, for example, the sixth, ie even-numbered sheet 3 of the stack 1.
  • the carriage 11 first returns to the first end position 9 (FIG. 1) in an empty run. From there its journey begins in the direction 36, moves over the offset distance L and triggers the signal necessary for opening the control valve 47 (FIG. 3) when the sensor 37 passes over the front edge of the cover sheet 39.

  • the sliding surface 55 extends in the stacking plane 5 symmetrically to the axis of the central guide roller 14.
  • the length of the sliding surface 55 corresponds, for example, to the diameter of the central guide roller 14.
  • the two gaps between the ends of the sliding block 54 and the lines of contact of the outer guide rollers 13, 15 the stacking level 5 determine a minimum necessary length of the offset distance L.
  • the slide shoe 54 When the cover sheet 39 is lifted off with the suction cups 43, the slide shoe 54 is located on the offset distance L of the sheet 3 lying directly below the cover sheet 39 and prevents the unintentional simultaneous picking up of a second sheet 3. This process can occur if the sheets 3 are partially damaged or if the sheets are too fast Lifting off the cover sheet 39 from the exactly aligned stack 1 also occurs with the sheets 3 intact.
  • the sliding shoe 54 can also be combined with the deflectors 40 (FIG. 2). Instead of the slide shoe 54, rotatably mounted rollers can also be used here, the axes of which are arranged parallel to the roller axes 41 and the rollers of which roll in the stacking plane 5.
