Definitions

  • the invention relates to a method and a non-stop boom device for a sheet-processing printing machine according to the preamble of the claims 1 and 4.
  • a method and a device of this type is known from DE 43 17 357 C1 and DE 44 05 586 C1 known. Thereafter, a boom device has front and rear sheet stops for aligning the sheets to be deposited and one counter auxiliary stacking pad that can be inserted in the direction of sheet travel, e.g. one Rake or board to catch sheets when changing stacks. This is done when inserting the auxiliary stack pad, a separation of the main and Auxiliary pile.
  • This non-stop boom device has proven itself, but it should be noted that that when inserting the auxiliary stacking pad, e.g. depending on the sheet format and / or basis weight of the printing material and the machine speed, enclosed in the delivery stack between the individual sheets There are air cushions.
  • the object of the invention is a method and a non-stop boom device for a sheet-fed printing machine to create the above Avoids disadvantages, in particular a uniform insertion of the auxiliary stack pad permitted and avoids moving and deforming sheets.
  • the uppermost one becomes when an auxiliary stacking pad is inserted Sheet of the main stack in the area of its leading edge with the neighboring, sheet of the main stack underneath fixed in position.
  • the position is fixed preferably by a horizontal frictional connection at the front edges (Gripper edge) of the adjacent upper sheet in the main stack, which is marked by one of approximately vertically acting force and / or on top of the top sheet
  • Form fit is achieved.
  • the form fit can cover several sheets extend.
  • a non-stop delivery device 1 essentially consists of a circulating chain system 4 with gripper systems 3, which feed the sheets 2 coming from an upstream printing unit or a finishing unit to a main stack 5 in the sheet running direction 9.
  • the sheets 2 are guided past fixed sheet guiding devices 8 and the sheet guiding devices 10, which are adjustable depending on the format and printed image.
  • the sheet guiding devices 8, 10 are selectively controllable with blowing or suction air.
  • a blowing device 6 is arranged in a field above the main stack 5 and supports the depositing of the incoming sheets 2 onto the main stack 5 or an auxiliary stack 28.
  • the incoming sheets 2 are braked in a known manner by a sheet brake 7 and placed on the main stack 5 against leading edge stops 11.
  • pivotable guides 15, for example angle rails, are arranged for receiving an auxiliary stacking base 12, for example a board or rake.
  • auxiliary stacking base 12 for example a board or rake.
  • known front sheet holders 14 are arranged which extend over the sheet width and can optionally be supplied with blowing or suction air.
  • the front sheet retainers 14 are inclined at an acute angle to the horizontal in the area of the main stack 5 or auxiliary stack 28.
  • the front sheet holder 14 can be moved from a waiting position in the leading edge area, outside of main / auxiliary stacks 5, 28, directly into the area of main or auxiliary stacks 5, 28 below the incoming gripper systems 3 and with the incoming sheets 2 to form the Auxiliary stack 28 can be lowered.
  • Two hold-down devices 17 are arranged at intervals across the format width. Depending on the application can only be used a hold-down 17. For larger ones Format widths can also be used with multiple hold-down devices 17.
  • Both hold-down devices 17 are from an approximately vertical waiting position (dash-dot representation), which is parallel to the front edge of the main stack 5, in a Swiveling position in which each hold-down device 17 on the top sheet 16 as well as in succession to further adjacent sheets 2 of the main stack 5 in the area the front edge acts.
  • each hold-down device 17 is pivotably supported by means of a hollow shaft 24.
  • a hollow shaft 24 At the Hollow shaft 24 is attached to a tab 18 which in a swivel 25 with a Actuator 19, e.g. a pneumatic cylinder is.
  • the hold-down device 17 itself has a swivel joint 29 with a coupling 26 is connected to the hollow shaft 24.
  • the gear members are pivotable about the axis 20.
  • the tension spring 21 ensures that the cam 23 is always non-positively guided on the roller 22.
  • the law of motion of the Control curve 23 is formed such that the hold-down device 17 from the vertical Waiting position (dash-dot representation) in the area of the main / auxiliary stack 5.28 can be swiveled in and then in approximately vertical direction of movement onto the top sheet 16 is movable. With the approximately vertical movement becomes a Pushing the hold-down device 17 avoided.
  • the hold-down device 17 has a tip that is non-positively on the uppermost sheet 16 and in succession acts on the adjacent sheet 2 below and is spring-loaded.
  • the tip can also be short needles or have similar configurations, the top sheet 16 and the adjacent the underlying sheet 2 of the main stack 5 is positively fixed in position.
  • the hold-down devices 17 are also synchronous by means of a corresponding transmission technology Coupling of only one actuator 19 can be activated.
  • a traverse with fixed stops is on in the area of the rear edge of the stack a format-adjustable sheet brake arranged.
  • the separator for the rear edge of the main stack 5 is in the Reference introduction referred to prior art.
  • the sheets 2 are fed and deposited by the gripper systems 3 in the sheet running direction 9 to the main stack 5.
  • the main stack 5 lies on a deposit table (not shown) which can be lowered in accordance with the increasing stack height. If the main stack 5 has reached a predetermined height, the auxiliary stack 28 is formed while printing continues. The main stack 5 is thus lowered further towards the floor and can be removed from the delivery area after the auxiliary stack support 12 has been inserted.
  • the front sheet retainers 14 activated by a sensor are inclined at an acute angle to the horizontal directly below the rotating gripper systems 3 into the area of the main / auxiliary stacks 5, 28.
  • the following sheets 2 are supported in the area of the front edge and begin to form the auxiliary stack 28.
  • the front sheet holder 14 can be acted upon by suction air to form the auxiliary stack 28.
  • the bottom sheet 2 of the auxiliary stack 28 is thus fixed in position.
  • a sensor for example a reflex head, activates the lowering of the auxiliary stack 5, so that the gap becomes a space so that the auxiliary stack pad 12 can be inserted in the insertion direction 13 (counter to the sheet travel direction 9).
  • the auxiliary stacking pad 12 When the auxiliary stacking pad 12 is pushed in, the actuating device 19 is activated in a sensor-controlled manner, the hold-down device 17 swivels from its waiting position into the area of the main stack 5 by means of a coupling mechanism and non-positively fixes the uppermost sheet 16 of the main stack 5 in the area of the leading edge in the vertical direction with the neighboring ones, below lying sheet 2 in the main stack 5.
  • the auxiliary stack pad 12 can be inserted up to the trailing edge stop without the uppermost sheet 16 or (underneath) adjacent sheet 2 of the auxiliary stack 5 being able to be displaced in the direction of the sheet emergence. Possible air cushions included in the main stack 5 do not have a negative effect when changing the stack.
  • the front sheet support 14 When the auxiliary stack support 12 reaches its end position, the front sheet support 14 is moved back out of the area of the auxiliary stack 28. The air supply is reversed in that the bottom sheet of the auxiliary stack 28 is separated from the front sheet holder 14 by blowing air. The hold-down device 17 then swings back into its waiting position. The main stack 5 can be run. The depositing table of the main stack 5 is moved to the upper starting position on roller chains and takes over the auxiliary stack support 12 with the auxiliary stack 28.
