Definitions
- the invention relates to a stack logistics of a printing machine for printing on a sheet front and for printing a sheet back.
- Printing presses are generally known (EP 051 2549), in which a double sheet pass and a turning of the stack before the second sheet pass to print the sheet back is required for printing on the sheet front and for subsequent printing on the sheet back.
- 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.
- the printing of a sheet front and the printing of a sheet back of a sheet conveyed from a feeder sheet stack via at least one sheet guide cylinder interacting directly or indirectly with at least one inkable printing form cylinder to a delivery sheet stack is also possible in that the sheet to be printed is removed from the feeder sheet stack, from the sheet guide cylinder to Printing on the reverse side of the sheet, printing on the reverse side of the sheet, transferring the printed sheet with a sheet transport direction to the delivery sheet stack against the sheet running direction to the sheet guide cylinder.
- ported, placed on the delivery sheet stack arranged in the same plane in front of the feeder sheet stack relative to the sheet running direction with the printed sheet back upwards and the delivery sheet stack can be brought into the position of the feeder sheet stack for subsequent printing of the sheet front side.
- the object of the invention is to provide a stack logistics for a printing machine for printing on the front of the sheet and subsequent printing on the back of the sheet.
- Fig. 3 device for stack transport.
- the printing press contains a stack of feed sheets 1, conveying elements 2, further conveying elements 3, a sheet-guiding cylinder 4 designed as a printing cylinder, which interacts with two offset cylinders 5, each printing 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 removed from the stack of feeder sheets 1 transported 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.
- the investor sheet pile 1 and the delivery sheet stack 11 is disposed in 'the same stack level 10th
- 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 guiding cylinder 4 is first printed on the back of the sheet based on this machine diagram, 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.
- Fig. 2 the handling of the feeder sheet stack 1 and the delivery sheet stack 11 when printing on the front and back of the sheet is 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. Then (diagram below) the feeder sheet stack 1 and the stack transport carriage 16 are passed through a vertical movement from the underside 19 of the cantilever arms 18 (FIG. 3) assigned to the respective stacking trolley 16 into its operating position.
- the printing process begins, i.e. 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 there with the printed back of the sheet facing upward - schematically indicated by a filled triangle - deposited.
- 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; then the stack transport carriage 16 of the feeder sheet stack 1 is lowered to the starting position mentioned at the beginning.
- the empty stack transport carriage 16 of the feeder sheet stack 1 is extended, the delivery sheet stack 11 is lowered onto the turntable 13, rotated through 180 ° and lowered onto the linear conveyor unit 8. Then (top right) the delivery sheet stack 11 is moved into the starting position of the feed sheet stack 1 and the empty stack transport carriage 16 of the feed sheet stack 1 is moved into the starting position of the delivery sheet stack 11 and then brought into the respective 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.
- the printing process begins again in the third phase, ie the sheets to be printed are Sheet stack 1 located delivery sheet stack 11 removed, printed on the back of the sheet, conveyed to the feed sheet stack 1 located in the position of the delivery sheet stack 11 and there with the printed sheet back upward - schematically indicated by a triangle - deposited.
- 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 shows the device for realizing the sequence described with reference to FIG. 2, the upper part of the figure showing a side view, the middle part of the figure a top view with the rotary table 13 in the rest position and the lower part of the figure showing a top view with the rotary table 13 in the working position.
- a cantilever arm 18 which is arranged symmetrically to the machine longitudinal axis 20, is arranged in the lateral region of feeder sheet stack 1 and delivery sheet stack 11.
- the use of cantilever arms for the vertical movement of the stacks ensures free passage of the stacks in the feeder and delivery area of the printing press.
- the cantilever arms are assigned to the underside 19 of the respective stacking trolleys 16.
- a linear conveyor unit 8 for example as a roller conveyor, is formed on both sides next to the cantilever arms, and a raceway 21 for the rollers 17 of the stacking trolleys 16 is arranged next to each linear conveyor unit 8.
- Each track 21 is laterally of at least one guardrail 22 limited, the rollers 17 being assigned to the guardrail.
- 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).
- the operation of the device is described below.
- the empty stack transport carriage 16 of the feeder sheet stack is lowered by the cantilever arms 18 onto the linear conveyor unit 8 by a vertical movement thereof and extended under the delivery sheet stack 11.
- the stack transport carriage 16 of the delivery sheet stack 11 with its rollers 17 is placed by a vertical movement of the cantilever arms 18 on the rotary table 13 which is in the working and lifting positions and rotated by 180 °.
- the underside 19 of the stack transport carriage 16 of the rotated delivery sheet stack is now placed on the linear conveyor unit 8 and, after a rotary movement of the rotary table, is moved into its rest position into the position of the feeder sheet stack 1.
