Definitions

  • the invention relates to a method for correcting trapezoidal register deviations with a clamping of the pressure plate trailing edge on at least two subsections, a test print for determining register deviations and a correction by changing the lateral distance of two of the subsections serving for clamping.
  • the invention relates to a device for performing this method with a clamping bar and a clamping bar having a fastening bar which serves to clamp the pressure plate trailing edge and which consists of at least two strip sections, at least one of which can be displaced by an adjusting device for lateral distance change.
  • the invention has for its object to provide a method and an apparatus by which a trapezoidal register deviation can be corrected even if the Clamping force for normal clamping of the pressure plate rear edge is too low for the pressure plate to spread.
  • the object is achieved in that in a method of the type mentioned above, the two partial sections provided for the lateral distance change are subjected to an additional clamping force before the correction.
  • the device of the specifically mentioned type for carrying out the method is further developed according to the invention in that the clamping and clamping strips of two strip sections can be acted upon by an additional clamping force by means of at least one blocking part in each case.
  • the advantage of the method according to the invention is that the high clamping force only has to be applied when such a trapezoidal correction of the register deviation is required. Since this is only the case with a few types of paper, the application of a high clamping force for each plate clamping would be uneconomical. Furthermore, the method and the device according to the invention make it possible to apply this high clamping force to relatively small areas of the pressure plate trailing edge, as a result of which it can be achieved with much less effort than if the high clamping force has to be applied to the entire clamping surface of the trailing edge. It is possible to apply the high clamping force to correct the trapezoidal register deviations with simple means, for example by means of a manual intervention. Despite automation, this is justified because, as already mentioned, the correction is not often necessary.
  • An additional task consists in developing the method and the device for correcting trapezoidal register deviations in such a way that the stretching of the printing plate does not start in one place or in a narrowly defined area but as evenly as possible over a large area of the printing plate.
  • the additional object is achieved in the method according to the invention in that, during the correction, a third central section of the pressure plate trailing edge is acted upon with a clamping force so dimensioned that stretching of the pressure plate is still possible in this clamping area.
  • a development of the device according to the invention is used in such a way that at least three strip sections are provided and that the outer strip sections are equipped with blocking parts and each with an adjusting device.
  • the at least one middle strip section is subjected to a clamping force dimensioned during the actuation of the actuating device such that an extension of the pressure plate is still possible in this clamping area.
  • the clamping force measured in this way can correspond to the clamping force for normal operation, which is to be applied to the entire rear edge in order to securely fix the printing plate for printing operation.
  • the above method can be carried out with the aid of radially displaceable counter-stops of the outer last adjusters of the clamping and tensioning device.
  • the displacement of these counter-stops in the radial direction leads to a pivoting of the corresponding section of the clamping and tensioning bar, as a result of which an additional expansion or a decrease in the tensioning force occurs.
  • an arched bulge in the middle area can be corrected, in the other case a concave deformation.
  • an expedient embodiment of the device for correcting trapezoidal register deviations provides that the actuating device is formed by an actuating shaft which passes through the last section and has an eccentric shape which interacts with the pressure cylinder.
  • the actuating shaft in a configuration for manual operation, is accessible for actuation on an end face of the fastening strip which is radially outer with respect to the pressure cylinder, the actuating shaft having a head which can be gripped with a tool at its actuating end.
  • a simple embodiment provides that the blocking part is designed as at least one screw, which in one of the Is screwed in and penetrates the other bar.
  • the additional clamping force must be achieved by tightening with a wrench, it being necessary to loosen the screws again after the correction has ended, since this additional clamping force must be released for the next pressure plate change. This applies in particular to control elements for an automatic plate change.
  • a somewhat more complex, but functionally reliable embodiment, which is also suitable for automation, provides that the blocking part has a locking cam which can be actuated by rotation, which is mounted in the clamping bar and can be set up against a blocking part counter-bearing which is firmly connected to the terminal block.
  • the blocking part counter-bearing can be designed as a plate held by two screws, the screws penetrating the clamping bar and thereby enclosing the mounting of the locking cam in the terminal block.
  • the locking cam has an eccentric curve, which is designed according to the additional clamping force to be applied.
  • This locking cam can have a head that can be gripped with a tool at its actuating end.
  • the blocking part is expediently accessible for actuation from the outer end face of the fastening strip. This additional clamping force must also be released for the next pressure plate change.
  • the head of the actuating shaft and the head of the locking cams are designed such that actuation with the same tool is possible.
  • a simultaneous clamping movement of the individual strip sections is achieved in that the clamping strips assigned to the strip sections have plug-in axes on their dividing surfaces have, and that the clamping strips are connected to one another in a rotationally fixed but axially displaceable manner via these stub axles.
  • a further development serves to simplify the construction of a fastening strip, which is designed in such a way that the clamping strips are mounted on corresponding clamping strips of the same length as pivotable double levers which can be pivoted against the force of clamping springs by an adjusting element in order to cancel the clamping position.
  • the strip sections which are provided for the additional clamping force, part of the clamping springs or all of the clamping springs can be arranged between the blocking part counterparts and shoulders in the terminal strip, the clamping springs surrounding the screws for the blocking part counter bearing.
  • a head of the adjusting screw which is accessible from the outside of the cylinder is designed such that it can be actuated with the same tool as the adjusting shaft and the locking cam.
  • the adjustability of the counter-stops can be designed such that their return is achieved by means of return springs arranged between the counter-stops and the pressure plate cylinder or that the screw heads are firmly guided in the counter-stops.
  • a zero position bar serves as a stop for the counter stop in its zero position.
  • the counter stop in the zero position is then centrifugally firmly against the zero position bar, but can be adjusted using the centrifugal pedal.
  • the zero position bar also prevents the set screw from being unscrewed too far.
  • the zero position bar largely covers the cylinder channel.
  • the device for correcting trapezoidal register deviations can of course also be automated.
  • drives are provided through which the actuating devices, such as the blocking parts, can be actuated.
  • Such drives can be installed in the printing plate cylinder or it can be provided that the drives are arranged outside the printing plate cylinder, wherein they can be brought into operative connection with the heads of the actuating device such as the blocking part in a predetermined position of the printing plate cylinder.
  • An automation of the lateral change in distance of last sections can take place in that the eccentric shape engages in an elongated hole on the inside of the clamping strip, axially extending straight walls of the elongated hole can be acted upon by the eccentric shape and the eccentric shape can be actuated by a motor arranged in the pressure plate cylinder via an adjusting shaft .
  • the application of the additional clamping force can be automated in that the locking cam can be actuated via a motor arranged in the terminal strip.
  • the arcuate register deviations are automatically corrected in that the adjusting screw can be rotated by means of a motor accommodated in the pressure plate cylinder.
  • detectors detect the adjustment paths of the adjustable strip sections.
  • the drives can be controlled from the machine control panel at the push of a button, with an indication of the adjustment paths being provided in the control panel.
  • the drives like the detectors, to be operatively connected to a control device which is used for the automatic correction of register errors.
  • Fig. 1 shows a printing plate cylinder 2, which is mounted in the side wall 33 of the printing press. Extending in the axial direction between the bearer rings 32 is the cylinder channel 36, in which a pressure plate fastening 34 for the front edge of the pressure plate and the fastening strip 1 for fastening the rear edge of the pressure plate are arranged.
  • the fastening strip 1 consists of three strip sections 1 ', 1'',1'''. Each of these strip sections consists of a clamping bar 4 and a clamping bar 3.
  • the pressure plate is clamped in ice, its end region is between Clamping strip 3 and clamping strip 4 clamped and then clamped by a joint movement of clamping strip 3 and clamping strip 4 in the clamping direction of the pressure plate.
  • Figure 1 shows the principle of the invention in a schematic manner. It does not matter to the invention how the terminal strip 3 and clamping strip 4 are designed in detail. Only the division of the fastening strip 1 is essential. However, the further figures show details of embodiments by means of which the method according to the invention can be implemented. The functions are explained using an example. However, the method and the device according to the invention can of course also be implemented with other specific embodiments. The prior art provides countless possibilities for designs of such fastening strips, which can also be designed according to the invention in the form of strip sections and in which it is also possible to provide adjusting devices and blocking parts.

  • This jaw-shaped formation is opened against the force of the clamping springs 18 in that an actuating element 25 pivots the clamping strip 4 and in the course of this pivoting movement Stop 27 of the terminal block 3 meets a counter stop 28 and thereby presses the rear end of the terminal block 3 in the direction of the clamping bar 4 (FIGS. 4 and 5). In this way, a gap is opened on the radially outward-facing end face 11 of the fastening strip 1, which gap receives the pressure plate trailing edge 6.

  • the locking cam 21 is designed such that it presses on the blocking part counter-bearing 17 during rotation.
  • the eccentric curve formation of the locking cam 21 serves to be able to set this force by means of the rotation of the locking cam 21. With increasing rotation of the locking cam 21, an increasing additional clamping force for clamping the trailed rear edge 6 of the pressure plate 5 can be applied to the clamping bar 4 by pressing the clamping bar 3.

  • the chamfered rear edge 6 of the pressure plate 5 is held in this area serving for clamping.
  • a stop 27 is arranged on the terminal block 3, which interacts with a counter stop 28. This interaction takes place in that the actuating element 25 pivots the clamping bar 4 against the tension spring 29 (or tension springs 29), as a result of which the stop 27 of the clamping bar 3 moves against the counter-stop 28, which is connected to the pressure plate cylinder 2.
