Definitions

  • the invention relates to a device for feeding sheets with a suction head for cyclical separation of the sheets from a stack of separating suction cups with transport suction cups for transporting the sheets in the sheet conveying direction to a belt table, the conveyor belts through which the sheets are transported in a scale-like manner and subsequently be fed to a sheet-processing machine with a drive for the Suction head and a drive for the conveyor belts that influence the conveying speed and the arc spacing can be switched.
  • the object of the invention is to change a generic device so that Optimal conditions for the handing over of the sheets from the transport suction cups can be realized on the conveyor belts.
  • the solution according to the invention makes it possible to increase the universality of sheet-processing machines by changing the staggered distance, the transfer conditions remaining constant regardless of the respective staggered distance.
  • the device for feeding sheets shown in FIG. 1 consists of a sheet feeder 1, a belt table 2 and front marks 3 assigned to the belt table 2.
  • the sheet feeder 1 has a suction head 4 with separating suction devices 5 and transport suction devices 6.
  • a sheet stack 8 consisting of sheets 7 is provided in sheet feeder 1.
  • the belt table 2 arranged downstream of the sheet feeder 1 in the sheet conveying direction 10 has a table plate 9 and belt rolls 11, 12 extending transversely to the sheet conveying direction 10.
  • the belt rollers 11, 12 are wrapped by one or more conveyor belts 13, which are guided by deflection rollers 14 and tensioning rollers 15.
  • the front marks 3 provided on the end of the belt table 2 facing away from the sheet feeder 1 can be moved periodically from the position shown in FIG. 1 to a position under the belt table 2 by means not shown.
  • the belt table 2 is further followed by an oscillating system 16 and a feed drum 17 of a sheet-processing machine, and in the region of the end facing the sheet feeder 1 a clock roller 18 corresponding to the belt roller 11 is assigned.
  • a drive 19, in the exemplary embodiment of the belt roll 11, is assigned to one of the belt rolls 11, 12.
  • the drive 19 consists of a transmission 19.1 and a transmission 19.2.
  • the uniform rotary motion derived from the downstream sheet-processing machine is fed to the transmission gearbox 19.1, which converts it into a sinusoidal rotary motion.
  • the transmission gear 19.1 is coupled to the belt roller 11.
  • the manual transmission 19.2 is provided with shift positions I, II, III, for example, it being possible for further shift positions to be provided.
  • switch position I a ratio of 1: 1 and thus, for example, such a spacing distance is realized that n sheets 7 lie on the conveyor table 2.
  • the switching position I the uniform rotary movement derived from the sheet processing machine arranged downstream of the sheet feeder 1 is fed to the drive 20 of the suction head 4 without being overlaid with another movement. If the switching position I of the transmission gear 19.1 is also set, a staggered spacing that is characteristic of the sheet feeder 1 and thus n sheets 7 on the belt table 2 as well as optimal transfer conditions when the sheets 7 are transferred from the transport suction devices 6 to the conveyor belts 13 are realized.
  • FIGS. 4 and 5 show the path and speed of the transport suction device 6 in the switching position I - thus n sheet 7 on the belt table 2 -, with the transfer of sheet 7 from in the transfer point U (in the exemplary embodiment at 90 ° of a single-turn shaft) the transport suction 6 to the conveyor belts 13 (Fig. 2 and 3).
  • the speed relationships between the transport suction devices 6 and the conveyor belts 12 are coordinated with one another and the transfer conditions are thus optimized. Since, as can be seen from FIGS. 2 and 3, in the switching positions II and III of the gearbox 19.2 in the transfer point Ü the path and speed profiles have been changed, the path and speed profiles of the transport suction devices 6 have to be tracked accordingly, what, as in the FIGS.
  • FIG. 7 shows the course of the speed W A of the drive 20 and shows that the instantaneous speed at the transfer point U is the same regardless of the selected switching position I, II or III.
  • the gearbox 19.2 and the gearbox 21 which realizes a sinusoidal output movement can be linked, so that the same gear stages are set for both gearboxes 19.2, 21 in each case for an actuating action. Irrespective of this, it is also possible to provide an electric motor 22 as the drive 19 and to assign an electric motor 23 to the suction head 4 as the drive 20.
  • the motors 22, 23 and thus the conveyor belts 13 and the suction head 4 are driven isochronously with the sheet-processing machine via a computer and control unit 24, by supplying the computer and control unit 24 with synchronization signals from the sheet-processing machine, whereby a such a spacing distance is realized that n sheets 7 lie on the conveyor table 2 and the transfer conditions are optimized.
  • a further sinusoidal drive of the conveyor belts 13 is also implemented in a known manner by the computer and control unit 24.
  • An input device 25 can also be used, in order to be able to change the scale spacing 1, for example to activate a transmission ratio n +1 or n - 1, as a result of which n + 1 sheet 7 or n - 1 sheet 7 are provided on the conveyor table 2.
  • the regulating and control device 24 is also assigned a memory 26 in that speed profiles are stored, which the motor 23 of the suction head 4 follows and thus drives the transport suction device 6 in such a way that when the staggered distance 1 changes, optimal transfer conditions for the transfer of the sheets 7 from the suction cups 6 are given to the conveyor belts 13.
