Definitions

the invention relates to a device for controlling grippers in sheet-fed rotary printing presses, which are combined to form a gripper row on a gripper shaft and are attached to rotating cylinders or drums, the gripper row being controlled via a gripper shaft, a drive lever carrying a roller and a control cam, and an adjusting device for Has adjustment of the opening width of the gripper.
DE-PS 834 107 a device for controlling grippers in sheet-fed rotary printing presses with two drives arranged parallel to one another has become known, which together produce a torsion spring a same or a different tension state twist and are arranged on each side of a printing cylinder.
This device relates to a pre-gripper control and not to the control of grippers of a rotating cylinder. It is not possible to adjust the opening width of the grippers, so that register differences occur.
the invention has for its object to provide a device of the type mentioned, which makes it possible to initiate a force build-up at a central location with the required accuracy for closing the grippers via two parallel drives on different substrates in order to avoid register differences and doubling phenomena at the same time .
the advantages achieved by the invention are that a faster gripper closure and a shortened build-up of force are brought about because, despite increased gripper forces, the bracing of the system gripper control cam, drive lever, roller, control shaft, gripper shaft and adjusting device is reduced. At a central point, the force is applied symmetrically to both cam controls on different substrates, so that register differences and doubling phenomena are avoided at the same time.
a number of at least one gripper row combined grippers 5 are mounted on a rotating pressure cylinder 8 or a drum.
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 an actuating device via a central adjusting device 3, preferably an adjusting screw with a scale Shaft 1 actuated, 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 force of both drives is introduced by 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 pretension by the spring rods 4 is 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. Due to the central arrangement, on the one hand, between the cam controls 6, 7 and, on the other hand, between the actuating shaft 1 and the gripper shaft 2, the torsional force is divided symmetrically and, at the same time, can be adjusted to different arc thicknesses with the required accuracy.
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 is rotatable and parallel to one another. lel are stored 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 in accordance with the geometry of the gripper 5 in all embodiments according to FIGS. 1 to 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. By choosing the lever length of the drive lever 11, the curve contour can be influenced favorably.
