Definitions

  • the invention relates to a stack handling of a printing machine for printing on a sheet front and for printing on the back of a sheet.
  • Printing presses are generally known (EP 0 512 549), in which a double pass through the sheet and a reversal of the stack before the second pass through the sheet are required to print on the back of the sheet for printing on the front of the sheet and for subsequent printing.
  • the high outlay for the second sheet pass and in particular for turning the sheet stack with an additional stack turning device is disadvantageous.
  • Printing machines are also known (DD 54 703), in which the sheet to be printed is first printed on the front side of the sheet, turned in the printing press, printed on the back side of the sheet and then placed on a delivery sheet stack with the back side up.
  • DD 54 703 Printing machines are also known (DD 54 703), in which the sheet to be printed is first printed on the front side of the sheet, turned in the printing press, printed on the back side of the sheet and then placed on a delivery sheet stack with the back side up.
  • Printing on a sheet front and printing on a sheet back one of a stack of feeders via at least one directly or indirectly with at least one inkable impression cylinder interacting sheet guide cylinder into one Delivery sheet stacks of conveyed sheets are also possible. that the one to be printed Sheet taken from the stack of feeder sheets, the sheet guide cylinder for printing on the Back of sheet fed, the back of sheet printed, the printed sheet with a sheet transport direction to the delivery sheet stack against the sheet running direction to the sheet guide cylinder transported on the relative to the sheet running direction in the same plane Delivery sheet stack with the printed sheet back arranged in front of the stack of feed sheets placed upwards and the delivery sheet stack for subsequent printing of the sheet front can be brought into the position of the stack of feeder sheets.
  • the object of the invention is to create a stack handling for a printing press Printing on the front of the sheet and subsequent printing on the back of the sheet.
  • the printing press contains a feeder sheet stack 1, conveying elements 2, further conveying elements 3, a sheet guiding cylinder 4 designed as a printing cylinder, which cooperates with two offset cylinders 5, with each offset cylinder being assigned a printing form cylinder 6 with two inking / dampening rollers 7, additional conveying elements 9 and a delivery sheet stack 11.
  • the sheet 12 to be printed is first transported from the feeder sheet stack 1 in the direction of the sheet guide cylinder 4, this direction is referred to as sheet travel direction 14.
  • the transfer of the printed sheets from the sheet guide cylinder 4 to the subsequent additional conveying elements 9 takes place counter to the sheet travel direction 14, this direction is referred to below as the sheet transport direction 15. Due to the change in the direction of sheet movement - sheet travel direction 14 in sheet transport direction 15 - the delivery sheet stack 11 is seen in the sheet travel direction 14, arranged in front of the feeder sheet stack 1.
  • the feeder sheet stack 1 and the delivery sheet stack 11 are arranged in the same stacking level 10.
  • the sheet stack 1; 11 are each assigned to a stack transport carriage 16, which are movable on the stacking level 10.
  • the sheet conveyed from the feeder sheet stack 1 to the sheet guide cylinder 4 is first printed on the back of the sheet based on this machine scheme, based on the position of the sheet on the feeder sheet stack 1, and is placed on the delivery sheet stack 11 with the printed sheet back upward.
  • This offers the possibility of bringing the delivery sheet stack 11 into the position of the feed sheet stack 1 by shifting or rotating it by 180 ° and shifting and immediately starting the subsequent printing of the front of the sheet in a second sheet pass without turning the stack.
  • Turning the stack offers the advantage that the contact edge relevant for high-quality printing is always at the front, ie when printing on the front of the sheet and when printing on the back of the sheet in the direction of sheet travel.
  • Fig. 2 the handling of the feeder sheet stack 1 and the delivery sheet stack 11 is at Printing of the sheet front and sheet back shown schematically.
  • the stack of feeder sheets 1 is moved into its starting position and the stack transport carriage 16 of the delivery sheet stack 11 is made available. Thereafter (diagram below), the stack of feeder sheets 1 and the stacking trolley 16 are brought into their operating position by a vertical movement from the underside 19 of the cantilever arms 18 (FIG. 3) associated with the respective stacking trolley 16.
  • the printing process begins, ie the sheets 12 to be printed are removed from the feeder sheet stack 1, printed on the back of the sheet - indicated schematically by a dashed triangle - conveyed to the delivery sheet stack 11 and stored there with the printed back of the sheet facing upward - indicated schematically by a filled triangle . This process continues until the feeder sheet stack 1 is empty and in its upper position and the delivery sheet stack 11 is full and in an intermediate position.
  • an upper runway 24 is swiveled in, the empty stack transport carriage 16 of the feeder sheet stack 1 is set down from the cantilever arms 18 onto the upper runway 24 and brought to the operating position of the delivery sheet stack on the upper runway, which is arranged obliquely.
  • the delivery sheet stack 11 is lowered from the cantilever arms 18 onto the turntable 13, rotated through 180 ° and lowered onto the linear conveyor unit 8. Then the delivery sheet stack 11 is moved into the starting position of the feeder sheet stack 1 and then brought into the operating position.
  • the second phase is shown in FIG. 2 in the embodiment with a turntable 13 and a linear conveyor unit 8.
  • the underside of the stack transport car 16 of the feeder sheet stack 1 and the delivery sheet stack 11 is assigned to the linear conveyor unit 8.
  • the rollers 17 of the stacking trolleys 16 are assigned to the rotary table 13. Now the printing process begins again in the third phase, that is to say the sheets to be printed are removed from the delivery sheet stack 11 located in the position of the delivery sheet stack 1, printed on the back of the sheet, conveyed to the delivery sheet stack 1 located in the position of the delivery sheet stack 11 and there with the printed back of the sheet upwards - schematically indicated by a triangle - filed. This process is continued until the delivery sheet stack 11 is empty and in its upper position and the feeder sheet stack 1 is full and in an intermediate position; then the stack transport carriage 16 of the delivery sheet stack 11 is lowered to the starting position mentioned at the beginning.
  • both the empty stack transport carriage 16 of the delivery sheet stack 11 and the feeder sheet stack 1 are extended with the sheets printed on both sides.
  • FIG. 3 the device for realizing the sequence described with reference to FIG. 2 is shown, in FIG. 3 the upper part of the figure showing a side view with the empty stack transport carriage 16 of the stack of feed sheets 1 in the position of the stack of feed sheets and the lower part of the figure showing a top view Working position of the turntable 13 represents. 4, the upper part of the figure shows a side view with the empty stack transport carriage 16 of the stack of feed sheets in the delivery sheet stack position, and the lower part of the figure shows a top view with the rotary table 13 in the rest position.
  • the cantilever arms 18 are assigned to the underside 19 of the respective stacking trolleys 16.
  • a linear conveyor unit 8 for example as a roller conveyor, is arranged on both sides next to the cantilever arms 18, and a track 21 for the rollers 17 of the stacking trolleys 16 is arranged next to each linear conveyor unit 8.
  • Each track 21 is laterally delimited by at least one guide rail 22, the rollers 17 being assigned to the guide rail.
  • the rollers are designed as combination rollers (rollers and guide rollers) equipped with lateral guide rollers.
  • the pivot point of the rotary table 13 is arranged on the machine longitudinal axis 20 in the region of the delivery sheet stack 11.
  • the turntable 13 is designed as a turntable / lifting table.
  • the turntable 13 is equipped with four support arms 23, which correspond to the rollers 17 of the stacking trolleys 16 in the working position (FIG. 3, lower part of the figure). In the rest position, the support arms 23 release the raceways 21 (FIG. 4, lower part of the figure).
  • an upper roller conveyor 24 for transporting the stack transport carriage 16 of the feeder sheet stack 1 into the operating position of the delivery sheet stack 11.
  • Each of the four upper runways 24 is equipped with a device for vertical movement 25. Furthermore, the upper runways can be pivoted from a horizontal position or inclined position into a vertical position, shown in broken lines in FIG. 4. The underside of the stacking trolley 16 is assigned to the upper runways 24.
  • the empty stack transport carriage 16 of the feeder sheet stack 1 is deposited by the cantilever arms 18 onto the upper runways 24, which were previously pivoted from their vertical position into the inclined position.
  • the underside 19 of the stacking trolley 16 is assigned to the upper runway 24.
  • the empty stacking trolley 16 is brought onto the upper runways 24 into the area of the delivery sheet stack 11.
  • the empty stack transport carriage 16 is taken over by the cantilever arms 18 of the delivery sheet stack 11 and brought into the operating position.
