Definitions

  • the invention relates to a gripper system for a sheet-fed printing machine for handling the transfer of an arcuate printing material.
  • the invention is directed to a gripper system which is connected to a continuously running as a chain or timing belt and rotating traction means and by which the substrate is transferred in a downstream of the printing units area by a drying and / or powdering station in the area of the sheet storage ,
  • Out DE 203 13 394 U1 is a boom for a sheet-fed press known which comprises a closed gripper chain device with a plurality of equidistantly connected thereto and rotating with the gripper chain device gripper systems.
  • a tapped from the last printing unit sheet can be passed through a drying station and a powdering station.
  • the path of the gripper chain device is determined by a gripper chain guide which typically comprises a plurality of deflection zones. The distance between these deflection zones can be dimensioned so large that the guided along the gripper system path arc is fully extended in phases.
  • the invention has for its object to provide solutions by which it is possible, in particular during the transport of a gripping systems gripped sheet over longer, rectilinear gripper track areas to achieve improvements in sheet travel behavior, so that this stable example, led by a drying and / or powdering station can be.
  • this curvature can form a simple curvature that bulges upward or downward transversely to the main plane of the arch. It is also possible to impose multiple waves on the bow, so that the bow is stiffened by several "longitudinal beads".
  • the tensioning stroke in this case in the area of the clamped curved transverse edge is preferably in the range of less than 10 to 15 millimeters.
  • the setting of said deviation of the clamped arc transverse edge of the transverse line is only temporary, so that the sheet stiffening according to the invention is brought about only in certain, typically relatively straight stretched Bogenlaufpfadabroughen.
  • the inventively brought about by slight adjustment of the positions of the gripper portions chucking the transverse edge is canceled again, so that the bow wrinkle free over the corresponding groove of the sheet smoother and thereby dive into it.
  • the gripper system is designed so that the position of the respective gripper opening portion relative to the gripper carriage carrying these is variable by the inventively provided adjusting means.
  • the gripper fingers may be designed to be elastic so that they tolerate the change in position of the gripper opening portion.
  • the gripper fingers are so involved in the inventive mime that the change in the position of the gripper opening portion without undue changes in the sheet clamping force in the gripper fingers takes place.
  • the adjusting means provided according to the invention for displacing the gripper opening section can be realized in particular with the inclusion of actuators, which as such are integrated in the gripper system and run with it.
  • the actuators may be designed as piezo actuators, in which the required travel is brought about by volume change of crystals by applying voltage.
  • the actuation of the adjusting means is preferably carried out such that the sheet transverse edge receives at least one transversely directed to the gripper carriage track bulge.
  • This bulge can be done so that the arc bulges either up or down. It is also possible to control a plurality of grippers of the gripper system in such a way that a web or bead structure is impressed on the printing material gripped by them.
  • the proposed according to the invention for curving the Bogenquerkante displacement of Greiferaufschlagabitese each other is preferably timed or matched with respect to certain gripper track sections, so that the stiffening takes place only in certain areas, especially a largely rectilinear stretched sheet travel path. It is possible to make use of the activation of the actuators proposed according to the invention only then, if the sheet travel behavior is assessed as unsatisfactory, especially if fluttering of the printing material is detected by sensors integrated in the corresponding machine.
  • the in FIG. 1 shown gripper carriage 1 is involved in a conventional manner in a here shown only gripper chain system 2 and serves in particular the transfer of a printing sheet 3 from the output area of the last printing unit of a printing press and the shipment of the sheet to a sheet storage area.
  • the gripper carriage 1 is provided with a plurality of spaced-apart grippers 4.
  • FIG. 3 shows a gripper finger 5 and a gripper opening portion 6, wherein the gripper fingers 5 can be brought into an open state, in which either a Jerusalem motifder sheet introduced into the gripper system, or a just be deposited sheet can be released.
  • gripper fingers 5 cooperate in each case with the gripper impact section 6, wherein this gripper opening section 6 provides a seating surface K onto which the gripped printed sheet is clamped by the gripper finger 5.
  • the gripper system shown here is characterized in that it is equipped with adjusting means by which a defined by the gripper system Bogenquerkanten Scheme Q a defined deviation from a the edge-side corners P1, P2 of the sheet 3 connecting transverse line g can be awarded.
  • the control of the individual gripper 4 of the gripper system 1 is preferably such that the recognizable, "wavy" Aufgriff the sheet B and thus caused by Lekssicken Struktur stiffening only temporarily, i. takes place for a specific section of the sheet career. Otherwise, the printed sheet B is picked up substantially straight, so that it can be curved wrinkle-free outside of the stiffening region about a transverse to the sheet running direction BLR axis X.
  • the clamping of the transverse edge Q of the sheet B is carried out such that on the signature B two upwardly bulging longitudinal beads W1, W2, and an intermediate, down bulging longitudinal bead W3 results.
  • This concept becomes a special one achieved effective temporary L jossaussteifung the press sheet B in a specific Bogenbahnabêt a boom.
  • FIG. 2 is a conventional gripper system shown by which the sheet B is taken straight in the region of its front transverse edge Q.
  • the sheet B stretched in this way can, as indicated here, form corrugations running transversely to the direction of sheet travel BLR and thereby flutter.
  • FIG. 3 a preferred construction of a gripper system according to the invention is shown.
  • This gripper system comprises a gripper carriage spar 10, here made of an extruded profile material, on which, in the longitudinal direction, a plurality of gripper fingers 5 are pivotably mounted on a gripper shaft 11.
  • These gripper fingers 5 together with a gripper impact section 6 each have a clamping gap K, via which a sheet to be transported can be picked up and fixed.
  • the gripper impact section is seated on an adjusting means 12, which is designed here as a piezo actuator. It is possible to form the grippers in such a way that they can be actuated individually or in groups by an actuator which is assigned to the respective gripper or gripper group.
  • the grippers in such a way that the respective gripper fingers can be displaced with an impact strip section associated therewith as a gripping module for bringing about the sheet edge deflection.
  • This module can be controlled by a corresponding actuator which is preferably designed as a high-stiff actuator.
  • a corresponding actuator which is preferably designed as a high-stiff actuator.
  • These actuators can be embodied as electromechanical and / or hydraulic or pneumatic, and in particular also as piezoactuators.
  • the adjusting means 12 By the adjusting means 12, it is possible to change the position of the clamping gap 12 defined by the dimension s indicated here. This makes it possible to give the tensioned by the adjacent gripper fingers 5 transverse edge of the sheet to be transported a certain ripple and the bow thereby stiffen.
  • the actuation of the actuating means 12 embodied as piezoactuators takes place via a power circuit 13.
  • This power circuit 13 is provided here merely by way of example with a sliding contact 14, by means of which a voltage supply and a corresponding control by a sliding rail element 15 take place.
  • an electronic control system is integrated, which makes it possible to bring about a corresponding adjustment of the actuating means 12 by a aufmodulêtides on the supply voltage signal.
  • the grippers can be adjusted independently of each other in height by actuators and can thus impress the sheet a rigid in the sheet travel direction form. As a result, bowing problems are reduced and a better controllability of the bow is guaranteed.
  • the grippers of the gripper carriage are individually and independently of each other in height via actuators (for example by piezoelectric effect, magnetic, mechanical, pneumatic) adjustable.
  • the energy for this purpose for example, by an inductive principle, sliding contacts, energy storage (accumulator, condenser, pneumatic pressure accumulator) brought into the gripper system.
  • energy storage accumulator, condenser, pneumatic pressure accumulator
