Definitions

  • the invention relates to a gripper system for a sheet-fed printing machine for carrying out the transfer of an arcuate printing material at least along a portion of the total traversed by the respective printing sheet sheet travel path.
  • the invention is directed to a gripper system which is connected to a running as a chain or timing belt and circulating along a closed Wergopfads traction and by which the substrate between the printing units, or in a downstream of the printing units area is transferred to the area of sheet deposition.
  • Out DE 203 13 394 U1 is a boom for a sheet-fed press known which comprises a gripper chain device to which equally spaced a plurality of gripper systems are connected. About the respective gripper system a tapped from the upstream 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, with respect to the mechanical performance of gripper systems, and in particular with regard to the space requirements of the gripper systems, advantages over previous designs can be achieved.
  • the gripper actuator device can be designed such that the grippers integrated in the respective gripper carriages can be brought into the open state or into the closed state individually or in defined groups.
  • each gripper finger is associated with an actuator.
  • This actuator can then be designed so that the actuating forces generated by this are matched only to the actuating force requirement of the individual gripper finger, so that relatively small-sized, highly rigid actuators can be realized in this respect.
  • the gripper carriage is preferably designed as a flat structure according to a particular aspect of the present invention.
  • This flat structure may in particular be made of an aluminum extruded material or another Holmaterial, which is characterized by a high rigidity at relatively low weight. It is possible to make the gripper carriage so flat or heavy that its normal, i. Height measured perpendicular to the track substantially corresponds only to the measured also normal to the gripper carriage track chain width. It is also possible to manufacture the gripper carriage made of a highly rigid lightweight material, in particular a fiber-reinforced Kunnststoffmaterial, especially coal, Kevlar, or aramid fiber reinforced plastic composite material.
  • the gripper actuator device comprises an electromechanical actuator.
  • This electromechanical actuator can be realized in particular with the inclusion of an electromagnet.
  • a piezoelectric structure ie a crystal structure, by which a required travel is brought about piezoelectric way.
  • several piezoelectric elements can be arranged in a layered manner.
  • the introduction of the Aktuatorbetör concerns the introduction of the Aktuatorbetörs energie is preferably carried out while avoiding load fluctuations in the gripper chain train.
  • the introduction of the Aktuatorbetör concerns concerns the introduction of the Aktuatorbetörsonsenergie can be done by inductive means or possibly also by sliding contact structures.
  • a switching device in the respective gripper carriage, by means of which the control of the individual grippers of the respective gripper system, which is highly precise in terms of timing, coordinated or synchronized with the machine run, is signal-wise initiated. It is thus possible, on the one hand, to ensure a corresponding energy supply of the actuators in the area of the gripper carriages and, on the other hand, to make the activation of these actuators dependent on specific control signals, which are coupled into the gripper carriage area via an interface device.
  • This interface device can be arranged so that it is located at a position that allows signal transmission to the engaged in the gripper carriage switching device, when the gripper is in an actuation-relevant position.
  • Such interface devices are then arranged in the region of the Bogenaufgriffs, as well as in the sheet storage area. Furthermore, it is also possible to arrange a corresponding interface device in a track section suitable for taking a test sheet, which as such makes it possible to open the grippers at this special location.
  • the actuation of the actuators can be carried out by a control device which is located directly in the region of a boom or provided for the drive of the boom control cabinet. Otherwise, it is also possible to cause the actuation of the actuators from a machine control center.
  • FIG. 1 shows very simplified the end of a boom of a sheetfed press.
  • This boom comprises a plurality of gripper carriage 1, which is connected to a Gripper chain 2 are connected and thus in a conventional manner along the gripper chain path are movable.
  • each gripper carriage 1 a plurality of grippers 3 are included, each comprising a gripper finger 4 and a gripper extension section 5, wherein the gripper fingers 4 can be brought into an open state for introducing or releasing a sheet B, wherein a seat surface K is provided by the gripper opening portion 5, on which can be clamped by the gripper finger 4 of the respective réellebenderde sheet B.
  • the gripper system according to the invention is characterized in that one or more gripper actuator devices 6 are integrated into the respective gripper carriage 1, wherein this gripper actuator device 6 is designed such that the associated gripper 3 can be individually activated by it.
  • the kinematic guidance of the gripper fingers is designed in such a way that preferably no bow pushing occurs.
  • the gripper actuator 6 is designed such that the hooks incorporated into the gripper carriage 1 can be brought into the open state in defined groups by means of these grippers.
  • the control of the gripper system 1 shown here is carried out by a zoom guided to the gripper running actuator 7.
  • the actuator 7 is executed in this embodiment as a coil system having a plurality of coil cores 8, said coil core 8 associated windings can be controlled via a control unit C.
  • about these coil assemblies 8 it is possible to provide the required for the operation of the gripper carriage 1 gripper required actuation energy in an inductive or electromagnetic manner.
  • the control of the integrated in the gripper carriage 1 actuators 6 by the controller C is carried out such that the picked up by the gripper carriage sheet B is released at a programmatically predetermined delivery position.
  • a detection device 9 is provided, via which the position of the gripper carriage 1 or in particular the position of the front transverse edge of the sheet B can be detected.
  • the instantaneous rotational phase position of the boom or running position of the gripper carriage 1 can be detected via a signal pick-up device 10. If the gripper carriage 1 is located at the corresponding delivery location in the area of the activation device 7, then a corresponding opening of the gripper integrated into the gripper carriage 1 takes place via this activation device 7.
  • the entire control of the arm illustrated here, equipped with actuators integrated into the gripper carriage 1, can furthermore also be coordinated by a machine control station L.
  • FIG. 2 is shown greatly simplified an exemplary structure of a gripper system according to the invention.
  • This gripper system comprises a gripper carriage 1 with articulated thereto articulated fingers 4.
  • the articulation of the gripper fingers 4 takes place here by way of example by a plug-in axis 12 through which the gripper fingers 4 is pivotally mounted in the gripper carriage 1.
  • the gripper fingers 4 are urged by a spring device 13 shown here merely simplified in a closed position in which the Greiferfingerspitzen Scheme 4a clamps a suitably picked sheet on the provided by the impact section 5 clamping surface K.
  • the opening of the gripper system shown here can be done by a arranged in the immediate vicinity of the running path of this gripper carriage 1 coil device 14 is controlled by the control device C.
  • the magnetic field built up by the coil device 14 can cause magnetization of a yoke structure 15 indicated here, so that the gripper finger 4 partially received in this yoke structure 15 dips into the yoke device 15 against the biasing force applied by the spring device 13.
  • the gripper 3 is opened and a sheet clamped on the clamping surface K can be pulled out of the sheet clamping area defined between the gripper finger tip section 4 a and the impact section 5.
  • a corresponding actuating device is preferably also arranged in the region of the engagement positions.
  • the gripper system in such a way that it can be operated both electromechanically and mechanically Paths is controlled, so that, for example, the operation of the gripper system in the space provided for receiving a sheet path section is purely mechanical, being initiated against the delivery of the sheet from the gripper system actuator-controlled.
  • This actuator-controlled sheet output can be accomplished in such a way that in the area of the display, special stack patterns, in particular hurdle or packet displays, can be realized by setting the dispensing positions differently by setting the opening times of the gripper system for specific numbers of sheets.
  • the gripper system according to the invention is particularly suitable for the acquisition of the sheet from the last printing or coating unit and for transporting these sheets by the boom for display.
  • the grippers serve to provide the holding force required for the sheet transport.
  • the grippers are connected to actuators, wherein preferably a plurality of such actuators are distributed over the length of the respective gripper carriage. To open or close the gripper these actuators are driven accordingly.
  • the inventive concept makes it possible to realize gripper carriages with an extremely low overall height. As a result, the turbulence during transport of the sheet is counteracted by the boom a poor drying and powdering process.
  • the construction height of the system can be reduced.
  • dryers and pollinators can be brought closer to the bow.
  • parts can account for the gripper opening curve and its actuators. It is possible regardless of the opening time constant ramp for the gripper opening.
  • the cyclically recurring adjustment effort of the gripper can be omitted. Vibrations are avoided.
  • the grippers in the gripper carriage are opened individually or in groups via actuators (eg by piezoelectric effect, magnetic, mechanical, pneumatic).
  • the energy for the actuators is provided by an inductive principle, sliding contacts, energy storage (Accumulator, condenser, pneumatic pressure accumulator) introduced into the gripper system.
  • Corresponding guide structures can be designed in particular as Umlenkgleit Entryen, or pulleys. It is also possible to form these guide or support structures as support rollers with radially outwardly projecting support fingers connected thereto which radially support the gripper carriage in the area of the sheet transfer and preferably dive into catch recesses which are formed on the gripper carriage.
