Definitions

  • the invention relates to a device for sheet delivery in a sheet printing machine according to the preamble of claim 1.
  • the documents of DE-GM 80 31 209 describe a gripper system with a gripper carriage from a gripper bridge, on which sheet grippers are formed, support rollers with a slide bearing being provided on both machine sides to avoid a tilting movement of the gripper system about a tilt axis lying transversely to the sheet conveying direction Roll on a skid track in the area of processing stations.
  • the invention has for its object to develop a device according to the preamble of claim 1 to improve functional reliability and at the same time to achieve a low-noise and low-wear device.
  • An essential element of the invention is therefore the arrangement of a roller bearing support for the conveyor chains in areas of increased load, in order to thereby limit noise formation and to transmit occurring forces with reduced friction to raceways which are connected to the machine frame.
  • guides for the rollers with the roller bearings are preferably arranged in the region of a gripper opening curve acting on the grippers of the gripper system on the conveyor chains and in the region of a conveyor chain deflection or possibly also in the region of a conveyor chain deflection.
  • a further feature of the invention serves to support the task solution sought by the invention, according to which known C-profile chain guides are attached to the side walls of the printing machine in a flexible manner. This avoids strong impacts and the associated noise pollution when the forces acting on the conveyor chains are introduced into the machine frame.
  • a stud is attached to a bridge part, the bridge part being screwed to the guide with two screws, the axes of which are arranged eccentrically to the stud axis, and the stud into one Recess of the side wall protrudes. This achieves a soft attachment of the C-profile for the chain guides to the machine frame, which dampens the hard impacts that act on the conveyor chains.
  • chain guides 2 for an endlessly rotating conveyor chain 3 are fastened on both machine sides.
  • gripper systems 4 are attached at regular intervals from a gripper bridge 5 attached to both conveyor chains and sheet grippers 6 arranged thereon.
  • sheet grippers from a gripper finger 7 and a gripper support 8 are shown.
  • the gripper fingers are fastened on a gripper shaft 9 which can be pivoted against a spring and cooperate with the gripper support 8 fixed on the gripper bridge 5.
  • the opening of the bow gripper to release the with its edge between the The gripper finger 7 and the gripper support 8 are clamped by a curved roller arranged on the gripper shaft 9, not shown in the drawing, which cooperates with a fixed gripper opening curve 10 (FIG. 1).
  • the conveyor chains 3 are deflected by chain wheels 11 and 12 and are guided between the deflections 11 and 12 in the chain guides 2.
  • the chain guide consists of a cross-sectionally C-shaped profile as shown in FIG. 1.
  • the opposing end faces of the cross-sectionally C-shaped profile support the conveyor chains, which are designed as link chains, between the side link plates either slidingly on the chain pins or in a rolling manner from the rollers pushed onto the chain bolts.
  • the location of the load transfer from the chain guide 2 to the guide elements 13 for the rollers 14 or vice versa is structurally characterized by flat run-in and run-out angles.
  • additional guide elements 13 with a raceway are provided , against which rollers 14 supported on the conveyor chains are supported with a roller bearing.
  • these guide elements 13 can possibly only be arranged on the side of the direction of action of the additional forces, such as those that result from the gripper opening curve 10 or from centrifugal forces in the region of the deflections 11 and 12.
  • the rollers 14 with the roller bearing are arranged on chain bolts 15 which are elongated on one side and consist of roller bearings as are shown in the sectional view in FIG.
  • the rollers with the roller bearing are on each machine side between a conveyor chain and the front end of the gripper bridge 5 intended.
  • the chain guides 2 consisting of C-profile bars and the guide elements 13 preferably form a structural unit (FIGS. 6 and 7).
  • Two rollers 14 with roller bearings in the conveying direction are preferably arranged one behind the other on each machine side in order to avoid tilting movements of the gripper system and to achieve precise guidance of the gripper system perpendicular to the sheet conveying direction even under increased load.
  • 3 chain guides 2 are provided for the conveyor chains, which are screwed to the respective side wall 1 of the machine frame in a flexurally elastic manner as shown in FIG.
  • This is achieved by the interposition of a bridge element 16 with a stud bolt 17, pin or the like attached to it, which extends into a recess 18 of the side part 1 with a larger cross section and its bottom with the bottom of the recess 18 in the side wall 1 by a screw 19 is screwed.
  • the bridge element 16 is attached eccentrically to the central longitudinal axis of the stud 17 at a distance from this axis at two points by means of screws 20 on the chain guide 2 for the conveyor chain.
  • the connection of the chain guide 2 to the side wall 1 of the machine frame is thus flexible, and the elasticity can be determined by the choice of the dimensions and the material of the bridge element 16 or the stud 17.
  • the flexurally elastic connection of the chain guide 2 to the side part 1 is preferably used if rod-shaped C-profile elements are used for the chain guide on the side wall 1 of the machine frame, their connection to the side wall 1 according to the example of Figure 5.
  • the features of the invention are not only the wear reduced and causes less noise, but there is also a significantly lower lubricating oil load, which is an ecologically important advantage.
  • Rolling bearings are provided for the highly loaded points of the chain guide, so that the less loaded guide parts can optionally be made of plastic, both elements for the chain guide and elements of the guide for the rolling bearings.
  • toothed belts can possibly be used instead of conveyor chains, since the tensile forces in the conveying means are also reduced by the use of the inventive features. Toothed belts are usually made of plastic, require less lubricating oil and cause less noise.
