Definitions

the invention relates to a resilient gripper for sheet-fed rotary printing machines according to the preamble of the first claim.
resilient grippers are designed in such a way that they can evenly absorb the tension that is exerted on the grippers by the paper. Since a slight pulling out of the paper from the gripper causes doubling or registration problems, one always tries to design the gripper with the maximum holding force. This means that the gripper springs have a very steep characteristic. The bearing clearances of all grippers must also be kept very tight, since the slightest air automatically affects fitting or doubling when closing. This small bearing play inevitably leads to high friction of the grippers at the bearing point, i.e. that part of the closing spring force is consumed in the camp itself. It also follows from this that the bearings of the gripper shaft must be kept very stable in order to absorb a deformation when the grippers close impulsively. A disadvantage of this is the creation of very high mass forces.
DD-PS 66 634 From DD-PS 66 634 it is known to support a one-piece gripper lever on a gripper shaft and to adjust its pretensioning force by means of two compression springs.
the disadvantage is that the gripper lever determined its statically The position loses if the fullest possible compensation of the bearing force is to be achieved. With very high machine speeds and increased preload forces, adequate centering is no longer possible, for example as a result of spurious vibrations that are introduced into the machine.
Another disadvantage is the relatively large radius of inertia and the mass of the vibrating parts for initiating the holding process.
a gripper is known in which the axis of the gripper finger joint is pivotally mounted in a swivel joint parallel to the gripper shaft, the axis of the gripper finger joint being located approximately on the straight line extending away from the gripper tip, which is the supporting surface for the hook tip connects to the axis of the hook shaft.
the geometry shown in FIG. 1 shows that the force exerted by the gripper tip on the gripper support continues to have a component in the direction of sheet travel. As a result, there is still a risk of the sheet moving, and there is also a possible torsion of the gripper shaft with high pretensioning forces, although an improvement over conventional grippers with a circular movement about the gripper shaft axis can be achieved.
DD-PS 67 992 From DD-PS 67 992 it is known to mount a gripper by means of a clamping piece on a pivotable gripper shaft having a fixed axis and a gripper tongue in a first movement phase a circular movement around the gripper shaft axis and in a second movement phase an approximately perpendicular with respect to the gripper support To give movement.
This gripper arrangement also works a non-positively working parallel leaf spring arrangement and a gripper tongue that can not withstand large closing forces without bulging. The gripper is therefore completely unsuitable for the highest possible closing forces.
a vertically closing gripper with a controlled gripper shaft is known from DE-PS 2 030 040.
a disadvantage is the frictional control of the gripper shaft relative to the fulcrum of a control lever by means of a guide on a control cam.
the additional control effort leads to an increase in the inertial forces of the system vibrating with a large radius of inertia and thus to a reduction in the performance of the printing press.
the control cam is heavily soiled, it is no longer possible to guide the second vertical movement phase exactly.
the invention has for its object a resilient gripper of the type mentioned with regard to the mass and the carrier optimize the radii of the components and to give the gripper finger a movement perpendicular to the gripper support or a slight pulling movement in a second movement phase.
the advantages of the solution according to the invention are that irrespective of a soft gripper support without bulging the gripper tip in an extended speed range with high pretensioning forces and overpressures in the direction of sheet travel, neither disturbing forces nor vibrations can have an effect.
the holding effect is improved by an increased forced running of a vertical closing process or a closing process that takes place with little pulling movement.
the gripper finger maintains its statically determined position and does not react so slowly. There are also minimal gripper masses and minimal acceleration forces.
the gripper finger 2 cooperating with the gripper support 1 can be formed in one piece as a sheet metal part by means of links 11, 12 preloaded via stop screw 8 and stop 13, which are elastically deformable.
the handlebars 11, 12 are with a clamp piece firmly connected, which consists of preformed intertwined sheet metal strips 14, 15 which can be clamped on the gripper shaft 7 by means of a screw.
the links 11, 12 must also control a vertical movement or slight pulling movement of the gripper finger 2 in a second movement phase, which is similar to the movement that is generated by resilient guide elements in the form of leaf springs.
corresponding connecting lines of the links 11, 12 are provided, which likewise run through the fixed axis of the gripper shaft 7.
