  • the invention relates to a register web or register pin device for a sheet-fed printing machine which contributes as such in the context of the clamping of a printing or coating plate on a plate, or forme cylinder for aligning the corresponding plate.
  • the pressure plate is this purpose in the region of its front transverse edge accurately fitted with U-shaped punched in which dive when attaching the pressure plate to the plate clamping rail, the register pins in close fit.
  • the invention has for its object to provide solutions which make it possible to accomplish the establishment of a printing plate on an associated plate cylinder in a particularly advantageous manner.
  • the sensing element is designed as a mechanical Taststempel which provides a contactable by the pressure plate Tast Scheme.
  • This touch surface may be formed so that it extends over at least half the width of the register head portion.
  • the touch surface is preferably designed such that its curvature in a printing plate plane defined by the applied pressure plate substantially corresponds to the curvature of the recess surface of the pressure plate which is in contact with the touch surface.
  • Taststempel is integral with the register head portion.
  • the Taststkov this can be connected via integral spring joint structures to the register head section.
  • These spring-joint structures can be designed in such a way that a straight-guiding device is provided by them at least within the permissible Taststempelhub Schemees.
  • This straight guide device may in particular comprise a plurality of link sections and in this case be embodied as a parallel link guide device.
  • a sensor device For detecting the displacement of the feeler by the pressure plate present thereon, a sensor device is preferably provided, which serves as such to generate a signal indicative of a slight displacement of the Taststkovs relative to the register head section.
  • the sensor device can be designed as a switch that can take only two switching states. The first switching state, for example, signal the disengaged the position of Taststkovs. The second switching state is achieved when the Taststkov is retracted under the action of the applied pressure plate by a certain switching path, preferably to the end position. The end position then corresponds to the trigger point of the signal.
  • the switch can be designed in particular as a passive electromechanical switch with an integrated, encapsulated switching system.
  • the switch is preferably equipped with an overload protection. When using a plurality of such register webs, these are preferably designed so that they have substantially identical electrical and mechanical connection parameters.
  • this switch variant with two different switching states, or in particular also in combination with it, it is also possible to collect signals via the sensor device which as such are associated with the displacement of the Taststempels. Correlate way proportional.
  • This variant of the sensor device can be realized in particular by recourse to a strain gauge device or comparable measuring device. It is possible to set certain switching thresholds based on definable force / displacement parameters.
  • this DMS device in the region of the spring joint structure.
  • the tapping of the measurement signals generated by the sensor device can take place via a line led out of the register web device. It is possible already directly in the register web device, or at least still in the area the plate cylinder to provide a transmission circuit via which preferably in digital form corresponding information can be transmitted wirelessly from the area of the plate cylinder in the stationary area of the printing press.
  • the aforesaid wireless transmission of data indicative of the detection state of the sensor device can be accomplished, in particular, by means of a transponder winding which is signal-technically accessible from the upper region of the register web device.
  • reading elements communicating with this transponder winding can be provided, the positioning of these reading elements being accomplished in such a way that a data transmission in an angular position of the plate cylinder typically selected for the voltage of the printing plate is made possible.
  • the register web device can be designed so that it only serves to position the plate edge in the circumferential direction.
  • the side flank surfaces do not form any positioning surfaces.
  • the head portion may also be formed such that the side edge portions provided thereby provide a left and a right positioning flank surface.
  • These positioning flank surfaces can be designed as cylinder jacket sections.
  • the register web device can be connected directly to a plate cylinder.
  • the register web device according to the invention is connected to a tensioning rail. It is possible to provide an adjustment mechanism via which the absolute position of the register web device is adjustable. In particular, it is possible to form a slot recess in the anchoring section which is correspondingly displaceable relative to a clamping bolt.
  • FIG. 1 shows a register web 1 for a sheet-fed press.
  • This registering device 1 comprises an anchoring section 2 for anchoring the register web device 1 to a plate cylinder, not shown in more detail here, or in particular a peripheral to the plate cylinder tensioning rail system.
  • the register web device 1 furthermore comprises a register head section 3 which, as such, after insertion of a printing plate D dips into a register recess A of the printing plate D and has a left and a right side flank region 3a, 3b and a middle region 3c located between these side flank regions.
  • the register web device 1 is characterized in that the register head section 3 is provided with a feeler element in that central region 3c for detection the plant or the seat of the here shown in not deferred position printing plate D.
  • the feeler is designed as Taststempel 4 which has a contactable by the pressure plate D touch surface 4a.
  • the Taststempel 4 is formed integrally with the register head portion 3 and guided by spring joint structures 5a, 5b to the register head portion movable.
  • the spring joint structures 5a, 5b are designed in this embodiment as a parallel link. As a result, at least in the relevant stroke range a straight guide is accomplished.
  • a sensor device 7 is incorporated which serves as such for generating a signal indicative of the contacting of the touch surface 4a by the pressure plate D.
  • the sensor device 7 is here designed such that it detects a slight displacement of the Taststempels 4 relative to the register head section 3.
  • the sensor device is designed as a switch 6 as in the following in connection with the Figures 2 and 3 will be explained in more detail.
  • the switch 6 is formed in this embodiment in such a way that the switching path to be covered by the Taststempel 4 to the triggering of a switching signal is adjustable. This adjustment is achieved here by an externally accessible screw 8.
  • the head section 3 is designed such that its left and right side edge regions 3a, 3b respectively form positioning flank surfaces which in close fitting support the left and right inner walls a1 and a2 of the recess A of the pressure plate D transversely to the direction of rotation R.
  • the register web device 1 can in particular be connected to a tensioning rail via the slot recess 9 which can be seen here.
  • the circuit can be designed so that upon displacement of the Taststkovs contrary to the restoring forces generated by its suspension and possibly the sensor device, the switch 6 and the measuring cable 10 is switched to ground.
  • the measuring cable 10 it is also possible to carry out the measuring cable 10 as a multi-core cable, or to process the signal tap wirelessly, in particular optically or radio-based.
  • FIG. 1 differs from the exemplary embodiment FIG. 1 essentially only by the changed design of the integration of Taststkovs 4 in the head section 3.
  • the Taststempel 4 forms an integral part of the head portion 3 and the main body also comprising the anchoring portion 2.
  • the mobility of the Taststempels 4 is achieved by free cuts 11, 12 which can be made for example by wire erosion. These cutouts 11, 12 can be sealed by an elastomeric material, preferably vulcanized elastomers, so that no gaps are formed which are accessible to any impurities.
  • the joint structure created by the cutouts 11, 12 with the spring articulated structures 5a, 5b, 5c, which are statically overdetermined here but not unduly heavily loaded within the required stroke amplitude, is designed such that the restoring forces achieved thereby depend reliably on a pressure plate pending on the probe punch 4 can be overcome.
  • the switch 6 realized here comprises a contact element 6a designed here as a ball which is supported on an adjusting screw 8 in an insulated manner via an insulating plate 6b.
  • the contact element 6a is guided in a contact socket 6c.
  • the contact socket 6c in turn is embedded in an insulating body 6d.
  • the unloaded state of the Taststkovs 4 a here not closer recognizable switching gap causes.
  • By inserting the Taststkovs 4 in the head portion 3 of this switching gap is canceled and a contact between the contact element 6a and the Taststkov 4 generated.
  • By appropriate connection of the main body to ground and corresponding connection of the contact socket 6c to a sensor cable of the bridging state can be determined and hereby closed on a slot of Taststkovs 4.
  • the head portion 3 and the associated recess A of the pressure plate D are designed so that no side alignment of the pressure plate D is effected via the head portion 3, but only the contact state in the direction of rotation of the pressure plate D is determined.
  • the free cuts 11, 12 executed for displaceable integration of the tapping punch 4 in the head section 3 can be filled with an elastomeric material.
  • the switching device 6 differs constructively in details of the switching device 6 of the embodiment according to FIG. 2 , In principle, however, a contact gap S is also closed in this variant by displacement of the integral with the head section 3 Taststempels 4 and thereby the core 1 a of the measuring cable 10 connected to ground.
  • FIG. 4 a fourth variant of a register web device 1 according to the invention is shown.
  • the Taststempel 4 is guided over the integrally formed with the head portion 3 handlebars 5a, 5b, 5c, 5d.
  • the handlebar webs 5b, 5c lying in this representation act as deformation elements.
  • the deformation thereof, in particular the tensile extension of the lower handlebar brine is measured by a strain gauge 14 (strain gauge strip).
  • the signals generated via this DMS device 14 can be converted by an evaluation circuit and assigned to a displacement path x of the Taststempels 4. On the basis of the thus determined path information can be assessed based on a threshold, whether the Taststkov 4 has been moved so far that a proper positioning of a printing plate D is guaranteed.
