Definitions

  • the invention relates to a device for controlling grippers in sheet-fed rotary printing presses, which are combined to form a row of grippers and are attached to rotating cylinders or drums, the row of grippers being controlled by a gripper shaft and a first cam control, which is a central adjustment device for adjusting the opening width of the grippers having.
  • a device for controlling grippers in sheet-fed rotary printing presses of the type mentioned is known from DE-B-2 613 174.
  • the invention has for its object to develop a device of the type mentioned so that, taking into account the central adjustment of the opening width of the gripper, control of the gripper is achieved with uniform force build-up in the gripper shaft during the gripper closing movement.
  • the advantages achieved by the invention are that a quicker gripper closure and a shortened build-up of force are brought about, so that, despite increased gripper forces, the bracing of the system gripper control curve, roller, drive lever, actuating shaft, central adjusting device and gripper shaft for the opening width of the grippers is reduced.
  • the force is applied symmetrically to both cam controls by the adjusting device acting as a screw connection. This eliminates register differences and doubling effects caused by tension in the control system.
  • the adjusting device 3 which acts as a screw connection, allows the opening width of the grippers to be infinitely adjusted to the sheet thickness to be processed, as a result of which register differences are also avoided.
  • a number Z of a gripper row combined grippers 5 are attached on a revolving pressure cylinder 8 or a drum a number Z of a gripper row combined grippers 5 are attached.
  • the grippers 5 work together with a gripper support 9 and are controlled by a drive which has a cam control 6, 7 with drive levers 10, 11 and rollers 12, 13 on each side of the printing cylinder 8 or a drum.
  • a gripper shaft 2 is actuated by a central adjusting device 3 designed as a screw connection by an actuating shaft 1 which is positively connected to the drive levers 10, 11.
  • the actuating shaft 1 and the gripper shaft 2 are rotatably mounted in the measuring ring 14 of the pressure cylinder 8 or a drum.
  • the grippers 5 are opened by spring rods 4.
  • the rollers 12, 13 run on end faces around the circumference of the associated control cam 17, 18.
  • the control curves 17, 18 can have the same curves or, for positive control, both internal curves and external curves.
  • the introduction of the force of both drives takes place through the actuating shaft 1 via the central adjusting device 3 in the middle of the gripper shaft 2.
  • the actuating shaft 1 has an arm 19 on which an adjusting screw with a scale 3 is supported, which counteracts the preload by the Spring rods 4 are rotatably arranged in a bearing arm 20 of the gripper shaft 2 for the symmetrical drive connection and central adjustment of the gripper opening width to the sheet thickness to be processed.
  • the actuating shaft 1 is designed as a rigid torsion spring for compensating for manufacturing errors in the curves 17, 18. 1 and 2, the grippers 5 can be controlled via an actuating shaft 1 which is separate from the gripper shaft 2 and which are rotatable and mounted parallel to one another in the rotating pressure cylinder 8 or a drum. According to another embodiment according to FIGS. 3 and 4, the grippers 5 can be controlled via an actuating shaft 1 concentrically enclosed by a tubular gripper shaft 2. Finally, according to an embodiment according to FIG. 5, the grippers 5 can be controlled through the center of the pressure cylinder via a lever drive 15, 16.
  • the position of the gripper shaft 2 is selected according to the geometry of the gripper 5, while the position of the actuating shaft 1 according to the most favorable position for the control cams 17, 18 or the connecting parts 10, 11, 12 , 13, 15 is fixed.
  • the curve contour can be influenced favorably.
