Definitions

  • the invention relates to a gripper device for a printing press for handling sheet-like material with a gripper shaft which can be pivoted about its longitudinal axis and a gripper finger which has a resilient section and is rigidly connected to the gripper shaft such that the gripper tip in a first direction when the gripper shaft is pivoted a gripper pad is moved away and when pivoting in an opposite second direction comes into contact with this gripper pad and exerts a holding force on the gripper pad when pivoting further in the second direction, as well as with adjusting means for the contact of the gripper tip with the gripper pad.
  • Such a gripper device is known from EP-A-0 152 553.
  • the gripper finger is resilient and screwed onto a two-part clamping piece, which establishes the rotationally fixed connection to the gripper shaft.
  • this gripper device is closed, the tip of the gripper finger comes into contact with a gripper pad.
  • the gripper shaft is rotated by a further amount in the closing direction. The holding force results from the accompanying deflection of the gripper tip from its position in relation to the clamping piece when the gripper device is open.
  • the circular movement of the gripper tip is interrupted by the contact of the gripper tip with the gripper support and, as the gripper shaft rotates in the closing direction, the gripper finger behaves like one connecting rod resilient in the direction of rotation of a crank mechanism, firmly clamped on the crankshaft and guided in a crosshead, with the result that the gripper tip moves relative to the gripper support and thereby has a disruptive influence on the register accuracy of a clamped printed sheet.
  • a gripper device known from EP-B-0 073 955 uses the analogies of a generic gripper device to a crank mechanism in order to limit this sliding movement of the gripper tip to the smallest possible distance. For this purpose, it uses an angled resilient gripper finger, the resilient end of which faces the gripper shaft and the gripper tip of which lie on a common straight line through the center of the gripper shaft.
  • a Z-shaped shape of the gripper finger is intended to ensure that its straight sections behave approximately like the arms of a multi-joint lever articulated in the gripper finger's clamping point on the gripper shaft, in whose all joints restoring forces on the arms when the angular position of the arms changes act and the end corresponding to the gripper tip rests frictionally on the gripper pad under the holding force of the gripper finger.
  • the increase in the distance between the gripper support and the clamped end of the gripper finger associated with the rotation of the gripper shaft by the said additional amount to generate the holding force mentioned is said to bring about an automatic corresponding increase in the effective length of the gripper finger in this known device by deflecting the gripper finger in its longitudinal direction . This is to avoid moving the gripper tip on the gripper pad.
  • the desired effect is not achieved with the means disclosed there. Rather, due to its Z-shaped design, the gripper finger is highly flexible in its longitudinal direction determined by the center of the gripper shaft and by the gripper tip. This leads to the fact that the gripper tip shifts during the gripper closure or when tensile forces occur on the paper. The known gripper cannot counter this effect without additional measures.
  • this known device represents a so-called hook gripper, in which the additional rotation of the gripper shaft by the said amount is to be absorbed by the resilient support of the gripper finger in order to achieve a sufficient holding force.
  • the gripper is not rigid under load in its longitudinal direction determined by the center of the gripper shaft and by the gripper tip. Rather, the material guided around the gripper shaft allows the gripper to deflect in the longitudinal direction and leads to pushing on the paper.
  • a gripper finger the resilient portion of which, as in the exemplary embodiment according to claim 3, is formed from two spring bars connected in parallel and spaced apart, is known per se from US Pat. No. 3,536,321.
  • a spring assembly is rigidly attached to a first ring which can be rotated loosely about the gripper shaft and which is entrained in one direction of rotation by means of a driver pin by a second ring which is non-rotatably connected to the gripper shaft and is rotated in the other direction of rotation under the action of a tension spring against a stop .
  • a platform arranged of the loose ring penetrating guide rod which acts on the head end under the action of a compression spring supported against this platform in the closing direction and is pressed in the opposite direction by the second ring rotatably connected to the gripper shaft.
  • the overall arrangement is such that the spring bars are essentially relaxed when they come into contact with the gripper pad and the holding force is applied by the compression spring clamped between the end of the guide rod and the platform.
  • the spring bars take on the function of approximately parallel guidance of the gripper tip in the final phase of the closing movement.
  • a foot that is adjustable along the guide rod is provided, against which the other end of the compression spring supported on the one hand on the platform mentioned presses.
  • This gripper device is naturally associated with a certain amount of play in the storage of the gripper finger on the gripper shaft.
  • the mass forces of inertia change in every direction of rotation of the gripper shaft by running or loosening the loose ring from the driver. Through their interaction with the springs activated in each case, undesirable torsional vibrations of the entire gripper device also occur.
  • the object of the present invention is to design a gripper device of the type mentioned at the outset in such a way that the displacement of the gripper tip on the gripper support is almost zero with the simplest possible design of the gripper finger.
  • this object is achieved with a gripper device of the type mentioned at the outset in that the neutral fibers of the resilient section adjoining the gripper tip, when it is designed as a single spring rod, essentially in the plane determined by the longitudinal axis of the gripper shaft and by the gripper tip and during its formation in the form of mutually parallel, spaced apart spring bars in planes parallel to this plane.
  • the subject of the invention opens up the possibility, particularly when using only one spring bar, to create a device with a relatively low mass moment of inertia, which can advantageously be used in high-speed printing presses.
  • the embodiments of the subject matter of the invention can be easily assembled and disassembled.
  • the gripper shaft does not have to be removed from the machine for this.
  • the adjustment means also allow a precise individual adjustment of the contact of a gripper tip with the printed sheet clamped between it and the gripper pad, so that manufacturing tolerances and, if desired, differences in paper thickness can be easily compensated for.
  • the object of the invention ensures reproducible placement of the gripper tip at a defined contact point with the printed sheet, so that it is not subject to changes due to different gripper attacks.
  • the subject of the invention is particularly suitable for such an installation in a printing press that the center of the gripper shaft lies outside the imaginary extension of the sheet-like material clamped by the gripper device beyond its front edge.
  • a special shape of the gripper finger to achieve a pretension in the installed position may be dispensed with.
  • An advantageous embodiment of the subject of the invention is characterized in that a gripper finger with a resilient section designed as a single spring rod penetrates freely through the gripper shaft and is firmly clamped at its end facing away from the gripper tip for rigid connection to the gripper shaft.
  • Such a gripper device can be used advantageously in confined spaces. It allows the use of relatively long and therefore flexible gripper fingers with small distances between the gripper shaft and the gripper cushion, so that no inadmissible bending stresses occur.
  • Another embodiment is characterized in that in the region of the opening facing away from the gripper tip of a diametrical recess penetrated by the gripper finger, the cross sections of the recess and the spring bar are matched to one another to a small length.

  • the gripper finger can be rotated about its longitudinal axis and can therefore be particularly easily aligned for a full support on an associated gripper cushion, for which purpose the clamping device need only be loosened slightly.
  • the spring rod has at its end facing away from the gripper tip a cylindrical lug formed integrally with the spring rod, the longitudinal axis of which is aligned with the longitudinal axis of the diametrical recess and which is clamped between the clamping jaws clamped with the gripper shaft.
  • a further embodiment is characterized in that a second section of the spring bar, which is adapted to the outer contour of the gripper shaft, adjoins the resilient section of the gripper finger and is in contact with the gripper shaft and is clamped between the latter and a clamping piece having the adjusting means.
  • Such a gripper device can advantageously be used with sufficient space.
  • a further embodiment is characterized by a compression spring connected in parallel with the gripper finger in the form of a spring bar, with the direction of force essentially perpendicular to the neutral fibers, the compression spring being supported on a clamping device having the adjusting means for connecting the gripper finger to the gripper shaft.
  • a further embodiment is characterized in that gripper fingers, in which the neutral fibers of the resilient section run in planes parallel to the plane defined by the longitudinal axis of the gripper shaft and by the gripper tip, of a head part carrying the gripper tip, a foot part and one of the head part with the foot part connecting resilient section are formed in the form of two parallel spring bars and are connected in a rotationally fixed manner with the foot part directly to the gripper shaft.
  • Another embodiment is characterized in that the spring bars are arranged symmetrically to the gripper shaft.
  • This embodiment combines the advantage of simplified assembly with the applicability of a gripper device according to the invention in confined spaces, since in this case the spring bars can optionally be extended beyond the center of the gripper shaft.
  • a further embodiment is characterized in that one of the parts of the gripper finger connected to one another via the spring bars has an abutment of the adjusting means and the other part has an actuator of the adjusting means which is supported on the abutment.

  • a further embodiment is characterized in that adjustment means are provided in such a way that the gripper finger can be interlocked with them.
  • a further embodiment is characterized in that adjusting means designed to interlock the gripper finger have two adjusting screws spaced apart in the longitudinal direction of the gripper shaft.
