Definitions

  • the invention relates to an apparatus for picking up an auxiliary stack when conveying sheets in a printing machine.
  • German Patent DE 41 29 164 C1 corresponding to U.S. Pat. No. 5,242,261 to Pollich et al., describes a device for combining a residual sheet stack and a main sheet stack in the feeder of a sheet-fed printing press.
  • the device includes a load bearing plate for the residual sheet stack, which has rectangular grooves on its upper side. Rigid, straight, rectangular rods are provided at the spacing of the grooves for the temporary support of the residual stack. The rods are fastened rigidly to a crossmember.
  • German Published, Non-Prosecuted Patent Application DE 197 38 029 A1 contains a sheet feeder for a printing press, having an auxiliary stacking table in which rods are provided that are disposed parallel to one another and can be inserted into the plane of a stack.
  • resilient mounting of the rods in the form of a flexible crossmember is provided.
  • the resilient mounting has the effect that there is a difference in travel between the rods when the auxiliary stacking table is pulled out of the sheet feeder.
  • one part of the rods is fastened fixedly to a crossmember while another part of the rods is associated with the crossmember through springs.
  • Each spring is associated with a rod guide in which a rod can slide in the longitudinal direction.
  • the crossmember is moved with a drive to insert the rods into the grooves.
  • self-supporting chains are used as deposition elements for an auxiliary stack.
  • the chains are seated on chain sprockets in a parallel configuration.
  • a motor that acts on the chain sprockets is provided and guide plates and tubular pieces to guide the chains.
  • the mobility of the chains is defined by the geometry of the chain sprockets and chain links.
  • an apparatus for picking up an auxiliary stack when conveying sheets in a printing machine including a crossmember and loadbearing elements being disposed at the crossmember for picking up the auxiliary stack, the loadbearing elements being fastened movably to the crossmember to pivot in at least two degrees of freedom.
  • a chain mechanism having two sides and being coupled to the chain mechanism on both of the two sides, and the loadbearing elements being members pivotably connected to the crossmember.
  • the invention can be applied particularly advantageously in apparatuses in which pivotably connected members that can be moved on a curved path are used as loadbearing elements.
  • the apparatus takes up a small amount of volume in such a variant.
  • the ends of the loadbearing elements can be fastened in cutouts in the crossmember through joints.
  • the at least one joint movably connects the at least one loadbearing element to the crossmember.
  • the walls of a cutout can simultaneously form stops for the movement of a loadbearing element.
  • a loadbearing element in order for it to be possible to operate with constraining forces that are as low as possible, can be coupled to a crossmember through a joint that permits movement in four degrees of freedom.
  • a universal joint can be provided between the crossmember and a loadbearing element.
  • the loadbearing elements can be disposed in the crossmember so as to be displaceable within limits in the direction of the movement out of the grooves.
  • pairs of the loadbearing elements can have different limit regions for the displacement.
  • an apparatus for picking up an auxiliary stack when conveying sheets in a printing machine including a crossmember moving on a curved path and having cutouts, loadbearing elements being disposed at the crossmember for picking up the auxiliary stack, and at least one joint being disposed in at least one of the cutouts between the crossmember and at least one of the loadbearing elements and movably connecting the at least one loadbearing element to the crossmember in at least two degrees of freedom.
  • an apparatus for picking up an auxiliary stack when conveying sheets in a printing machine including a guide to be disposed adjacent a location for the auxiliary stack in the printing machine, a crossmember movably disposed at the guide, and loadbearing elements disposed at the crossmember for moving the auxiliary stack, the loadbearing elements being operatively connected to the crossmember to pivot in at least two degrees of freedom.
  • an apparatus for picking up the auxiliary stack when conveying the sheets including a crossmember and loadbearing elements disposed at the crossmember for picking up the auxiliary stack, the loadbearing elements being fastened movably to the crossmember to pivot in at least two degrees of freedom.

  • the pallet 10 lies on a stacking table 12 that can be positioned in the vertical direction 15 with the aid of chains 13 , 14 of a chain mechanism.
  • an auxiliary stack apparatus is provided to make it possible to refresh the stack 11 during continuous operation of the sheet-fed offset printing press.
  • the auxiliary stack apparatus includes a holder 16 for a plurality of loadbearing elements 17 disposed in parallel, an advancing device 18 , and a guide 19 for the loadbearing elements 17 , and a front loadbearing rail 20 .
  • the holder 16 can be positioned in the vertical direction by chains 21 of a chain mechanism together with the guide 19 and the advancing device 18 , and can be positioned in the horizontal direction perpendicularly with respect to the plane of the drawing of FIG. 1 by a non-illustrated positioning apparatus.
  • the loadbearing rail 20 can be positioned in the vertical direction 15 by chains 22 of a chain mechanism.
  • the pallet 10 has webs and grooves.
  • the stack 11 lies on the webs of the pallet 10 .

  • the stack 11 is guided against a suction head 23 having suction grippers 24 , 25 , using the chains 13 , 14 in accordance with the printing velocity.
  • Vacuum lines 26 lead to the suction grippers 24 , 25 .
  • the suction head 23 can be moved to and fro in the horizontal direction 27 .
  • the sheets 28 that lie on top of the stack 11 are separated using the suction grippers 24 , 25 and are conveyed onto a feed table 29 against front lays 30 by the movement of the suction head 23 .
  • the sheets 28 are transferred from the front lays 30 to the feed cylinder 8 by a swinging gripper 31 .
  • the sheet 28 is printed as it passes through the nip between the impression cylinder 7 and the transfer cylinder 6 .
  • the transport drum 9 transports the sheet 28 to further printing units.
  • the instant for refreshing the stack 11 has been reached.
  • the auxiliary stack 11 is picked up temporarily on the loadbearing elements 17 together with the remainder of the sheets 28 .
  • the holder 16 with the loadbearing elements 17 is positioned in the vertical and horizontal direction such that the tips 32 of the loadbearing elements 17 point approximately toward the centers of the cross-sectional areas of the pallet grooves.
  • the advancing device 18 is set in operation with a motor 33 and a mechanism 34 .
  • the loadbearing elements 17 that are fastened to a crossmember 35 pass through the pallet grooves onto the loadbearing rail 20 .
  • the loadbearing elements 17 are of pivotably connected members 36 that follow the curved shape of the guide 19 outside the pallet grooves and a guide in the holder 16 . After passing through the guide in the holder 16 and after lying on the loadbearing rail 20 , the members of the loadbearing elements 17 are flexurally rigid for the load of the auxiliary stack 11 . Furthermore, the auxiliary stack 11 is moved toward the suction grippers 24 , 25 by vertical driving of the holder 16 and the loadbearing rail 20 through the chain mechanism on the chains 21 , 22 . Here, the weight of the auxiliary stack 11 is completely held on the loadbearing elements 17 .
  • the stacking table 12 together with the pallet 10 is lowered on the chains 13 , 14 through the chain mechanisms until it assumes a lower position for picking up a new main stack.
  • the new main stack is moved under the loadbearing elements 17 of the auxiliary stack even before the auxiliary stack 11 has been processed.
  • the main stack and the auxiliary stack 11 are aligned.
  • the loadbearing elements 17 are drawn in in the direction of the guide 19 by the advancing device 18 .
  • the auxiliary stack 11 and the new main stack are combined to form a stack 11 .
  • the combined stack 11 is moved further toward the suction head 23 by the chain mechanism and the chains 13 , 14 .
