Definitions

the invention relates to a gripper system for preferably a cylinder of a sheet-fed rotary printing press, according to the preamble of patent claim 1.
One-piece grippers for cylinders or drums of rotary printing machines have become known, for example, from DE-PS 27 25 035.
This patent describes a one-piece gripper with a gripper tip, which is fastened directly to a pivotable gripper spindle by means of a screw and is pivotably supported thereon.
a compression spring is arranged, the abutment of which lies on the gripper spindle and the point of engagement on the gripper finger.
the gripper contact force F A is set depending on the deflection path X. Due to the torsion of the grippers wave, caused by the sum of the individual gripper bearing forces, and by inaccuracies when setting the individual grippers, the deflection paths X of the individual grippers are of course different. Desirable are now gripper "with a spring characteristic" very “stiff" and for a short fürfederungsweg X 1 merges into a horizontal line at a desired contact force F A target (X 1), that is, the gripper pad force F A independently of the deflection paths X would (Fig. 9 dash-dotted line).
the invention has for its object to provide a gripper system for sheet-fed rotary printing machines, in which the spring characteristic of the gripper can be designed such that the characteristic curve is relatively steep for a short deflection path, i.e. the contact force increases and, after reaching a certain deflection path, the characteristic curve changes into a horizontal or in the vicinity of a horizontal, so that the contact force is approximately independent of the deflection path.
a gripper spindle 1 consists of a tube 2.
the gripper spindle 1 is mounted in a known manner at its two ends in bearings 5 in a pit of a rubber or transfer cylinder 10.
a roller lever At one end of the gripper spindle 1, to drive this, a roller lever, not shown, is attached.
the gripper spindle 1 At the locations of the gripper spindle 1, at which the gripper 3 to be attached, the gripper spindle 1 is provided over a circumference of, for example 110 0, each with a recess. 4
the recess 4 ends in an extension 6.
the extension 6 is wider than a length of a hook bearing shaft 7 of the gripper 3. This extension 6 allows the hook 3 in a simple manner from the gripper spindle 1 Removing b zw.
V-shaped receptacles 8 are incorporated in the interior of the tube 2.
Receptacles 8 and gripper bearing shaft 7 each form a bearing point in which the gripper 3 can be pivoted.
An elastic, pressure-resistant hose 9 is arranged within the tube 2 of the gripper spindle 1.
An outer diameter D of the tube 9 corresponds approximately to an inner diameter d of the tube 2.
the tube 2 can be sealed at both ends 11 in the manner as shown in FIG. 4, for example.
a cover 12 is screwed onto both ends 11 of the tube 2.
the covers 12 each have a check valve 13 which open into an interior 14 of the hose 9.
the ends 11 of the tube 2 are each provided with a circular recess 16.
These punctures 16 serve as receptacles for an annular bead 17 at both ends of the hose 9.
the cover 12 When the cover 12 is screwed on, the bead 17 is pressed against a wall of the puncture 16 and thus the ends of the hose 9 are sealed.
the hose 9 is filled with compressed air via the check valve 13 and acts in the gas-filled state as a prestressed gas pressure spring.
a gripper foot 33 of the gripper 3 reaches through the recess 4 and is supported on the hose 9 (gas pressure spring 9).
Each of the one-piece grippers 3 has an on adjusting device 18 or 19 for changing an angular position c6 of a gripper tip 23 of the gripper 3 around the gripper bearing shaft 7.
the gripper tip 23 can hereby be adjusted to the associated gripper support 15.
the setting device 18 consists of a threaded bore 21 and a grub screw 22 which can be screwed into and out of it.
the threaded bore 21 is located near a gripper tip 23.
the adjusting device 19 for the gripper 3 consists of a threaded bore 24 in the tube 2, a screw 26 screwed into the threaded bore 24, a spring cup 27 placed on the screw 26 and a compression spring 29 supported between the tube 2 and a spring cup base 28
Wall 31 of the spring cup 27 is supported on one end 32 of the gripper foot 33 of the gripper 3.
the remaining part of the wall 31 has a non-positive connection with the tube 2 only via the compression spring 29 (FIG. 7).
the hose 9 sealed at both ends within the tube 2 thus forms a gas pressure spring in which the deformation path is small in relation to the enclosed gas volume.
gas springs With frictionless isentropic (adiabatic) compression, gas springs almost ideally show the behavior desired for grippers.
