Definitions
- the invention relates to a method for ascertaining a rotary position of a location-dependent cylinder of a printing press according to the preamble of claim 1.
- a device for a single-angle unit in which a stator of the single-angle unit is arranged at an angle relative to the side frame.
- DE 197 20 952 A1 describes a method for compensating a rotary movement superimposed on the rotary movement of a cylinder as a result of an eccentric movement.
- the compensation is carried out by means of a control loop which is given by the actual angle of rotation of the cylinder with respect to an eccentric and the actual angle of rotation of the eccentric or one thereof derived angle function is supplied.
- the invention has for its object to provide a method for determining a D rehwi nke l location of a place s rba ren cylinder of a printing press.
- the object is achieved by the features of claim 1.
- the position of the position does not have to be
- Movement of the cylinder against a side frame must be constant.
- Fig. 1 is a schematic representation of a
- Fig. 2 is a schematic representation of the side view of Fig. 1;
- Fig. 3 is a schematic representation of a
- Block diagram of a drive control
- Fig. 1 shows a longitudinal section of a rotating component of a printing press, 2.
- the cylinder 1 is rotatably mounted on its two outer Z cylinder lugs, of which only one is shown in FIG. 1, in an eccentric bush 3 by means of a bearing 4.
- the eccentric bushing 3 is in turn rotatably supported in a machine frame 6 in a slide bearing.
- the eccentric bush 3 is pivoted about the pivot axis 5 in a manner known per se.
- the pivot axis 5 is also the axis of rotation of the eccentric bush 3 in the machine frame 6.
- the distance between the cylinder axis of rotation 2 and the pivot axis 5 is the eccentricity e.
- a rotary shaft position 9 is secured against rotation relative to the axis of rotation 2 of the cylinder.
- the D rehwi nke l position encoder r 9 is formed by an inner ring 10 and a rigidly connected, k re isri ngförmi measuring disc 13.
- the anti-rotation attachment of the inner ring 10 on the journal of the cylinder 1 is indicated by a split pin 11.
- the measuring disk 13 has a known circular division with a plurality of lines running in the radial direction.
- the inner ring 10 is surrounded by a position which is rotatable thereon, with which the outer ring 14 is rigidly connected to a further circular disk 15.
- This second disc 15 is mt a plurality of photo elements for scanning the line division of the Provide measuring disc 13.
- photoelectric scanning which is only a preferred embodiment of the scanning, but to which the invention is not exclusively limited
- the relative rotational angles of the measuring disk 13 relative to the second disk 15, which are thus used as a reference serves for the Drehwi nke ll position of the first measuring disk 13, detected and therefrom the D rehwi nke l position of the cylinder 1 relative to the outer ring 14 serving as a reference element 14 with the second disk 15, hereinafter referred to as reference disk 15, determined.
- the outer ring 14 and the reference sheet 15 form a reference element for the contactor 9.
- a holding arm 30 is pivotally mounted on the masc frame 6 about a pivot axis 31. At its end facing away from the pivot axis 31, the holding arm 30 has an elongated recess 32, which in the exemplary embodiment is designed as a simple elongated hole.
- the pivot axis 31 of the holding arm 30 runs parallel to the cylinder axis of rotation 2.
- a rigid guide means 17, which is rigidly connected to the reference element 14, is positively guided in the recess 32 when the cylinder 1 is pivoted. Due to the positive guidance, the reference element 14 i printing operation, in particular also when pivoting the Zinder rotation axis 2, is held in its zero position.
- FIG. 2 the arrangement of FIG. 1 is in one Front view of the cylinder 1 shown.
- the cylinder 1 By means of a motor M or a working cylinder which engages on the eccentric bush 3, the cylinder 1 is pivoted about the pivot axis 5, which also represents the pivot axis of the cylinder 1, by an angle alpha from its zero position, namely the pressure position.
- the cylinder axis of rotation 2 describes a segment segment s in the swiveled-off position indicated by 2 ′.
- the reference element 14 is rigidly connected to the guide means 17, which is positively guided laterally closely spaced in the recess 32 of the holding arm 30.
- the guide means 17 is embodied as a simple square bolt which is slidably guided in the recess 32 in a purely translatory manner; this prevents tipping.
- the pivoting position of the reference element does not change when the cylinder 1 is pivoted by the pivoting angle Alpha of the cylinder 1, but by the smaller pivoting angle Beta of the holding arm 30.
- the cylinder 1 is from a first operating position, for. B. "Pressure ON” in a second operation 11 "Pressure AB" pivotable. If the cylinder 1 is arranged such that it cannot be rotated relative to the eccentric bush 3, for example, the rotor 13 and stator 15 of the rotary shaft 11 rotate 9 relative to one another. A second actual value Beta 2 related to the second operating position is determined. A correction value gamma is determined from a difference between an actual value Beta 1 and an actual value Beta 2 determined in a first operating position. If the cylinder is now driven in the second mode of operation, a computer 33 is acted upon with the previously determined correction value gamma and corrects the actually determined actual value during operation by this correction value gamma. That is, Both the actual value of the rotating component 1 and the correction value gamma are determined with a single rotary angle position sensor 9.
- This correction value gamma can also be calculated from the geometric conditions and determined without measurement using an angle encoder.
- a precalculated correction value gamma is thus fed to the computer 33 as a "manually" determined constant.
- correction values can be determined, for example, in accordance with the temporal course of the change in position of the cylinder, i. H. a function of correction values as a function of time.
- the cylinder 1 it is also possible for the cylinder 1 to have a position sensor assign, which determines a position of the eccentric bush 3 and thus the axis of rotation of the cylinder with respect to the machine frame 6. It is thus possible to determine correction values as a function of a position of the cylinder 1.
- the position of the cylinder means the position of the Z axis of rotation 2 of the cylinder 1 in relation to the machine frame 6.
- the computer 33 is a Le is ungs part 34 for controlling a drive motor 36 for driving the cylinder 1 downstream.
- Beta 1 actual value determined Beta 2 actual value, related
