Definitions

  • the invention relates to a device for the controlled feeding of strip material to printing machines according to the preamble of claim 1.
  • a device in which the web tension of a paper web is kept constant by means of a tensioning roller designed as a dancer roller.
  • a tensioning roller designed as a dancer roller.
  • a pull roller with a shaft gear arranged upstream of the dancer roller is provided.
  • the shaft gear is driven by a second reversible control motor, which is connected to the dancer roller via a control circuit. The speeds of the main drive and the control motor are additively superimposed by means of the shaft gear.
  • the control device used receives from a strain gauge measuring element a voltage signal proportional to the deflection of the tensioning roller and combines this multiplicatively with a signal proportional to the tension roller speed (proportional gain), here the speed-dependent proportional portion of the controller is placed in the measuring element.
  • DE-A1 25 49 762 shows a drive for a pair of pull rollers.
  • the machine is driven by a gearbox, the transmission ratio of which can be changed by means of an electric drive.
  • the change and thus the setting of the gear ratio occurs depending on the position of a pendulum roller.
  • the invention has for its object an improved device for the return of a deflectable, wrapped by a paper web tension roller in a to create a preselectable starting point.
  • the advantages of the invention are that the feed device can be adjusted manually to different paper web tensions which are required for different types of paper even if the control motor or the controller fails.
  • control device is driven by the main drive of the printing press, so that expensive additional units can be dispensed with. This measure not only reduces the manufacturing costs, but also reduces the susceptibility to failure of the entire device.
  • control device ensures a robust, stable system, i. H. a statically and dynamically uniform web tension.
  • the particular advantage of the device is that if the controller or servomotor fails, the device can be operated with a manually selectable constant extension (lag) to the printing unit. In this case, the compensation of the dynamic disturbances by the dancer roller is omitted, but in the long run a web tension can still be selected manually for the different papers, so in general an emergency production is possible.
  • a feed mechanism 1 of a printing press has a device for the controlled feeding of strip material 7 (eg paper web) between two cooperating pick-up rollers 2, 3 and a paper roll 4 of a roll changer 6.
  • the device 6 has u. a. a pull roller 8, which cooperates with a pressure roller 9.
  • the pressure roller 9 is rotatably mounted in the center on two levers 12 which are pivoted with a first end 11 and are laterally symmetrical on side frames 10 of the feed mechanism 1.
  • a second end 13 of the levers 12 is each articulated to a piston 14 of an impression roller (pressure device) 17.
  • the impression rollers 17 consisting of cylinders 16 and pistons 14 are fastened to the side frames 10 of the feed mechanism 1.
  • the pull roller 8 is rotatably mounted in side frames 10 of the feed mechanism 1 and projects through the side frame 10 with a shaft journal 19 on the drive side.
  • a gear 21 which with a gear 22 arranged vertically below is in meshing engagement.
  • the gear 22 is firmly connected to an output part 23 of an addition gear 24 (e.g. harmonic drive, differential gear, planetary gear).
  • a drive part 26 of the addition gear 24 has a gear 27 which meshes with a gear 28 that can be engaged or disengaged.
  • the coupling for the gear 28 serves to separate the feed mechanism drive from the main drive of the printing press (for example, for cleaning the cylinders) and, since it is not part of the inventive concept, is not further described.
  • the gear wheel 28 meshes with a gear wheel 29 of a shaft 31, which is in drive connection via a bevel gear 32 with a longitudinal shaft 33 driven by the main drive of the printing press.
  • a control part 34 (wave generator) of the addition gear 24 is firmly connected to a gear 36.
  • the gearwheel 36 meshes with a gearwheel 37, which is firmly seated on an output shaft 38 of a continuously variable adjustment disk transmission 39 (PIV transmission).
  • a drive shaft 42 of the adjusting disk gear 39 rotatably carries a gear 43, which is also in mesh with the gear 22 of the driven part 23 of the addition gear 24.
  • the gear 43 in meshing engagement with the gear 27 of the drive part 26 of the addition gear 24.
  • the adjusting disk gear 39 has an actuating device which can be driven by means of an actuating motor 46.
  • the servomotor is powered by a power driver 47 Regulator 48 fed.
  • a handwheel 40 is provided for manual adjustment.
  • a first paper web guide roller 51 is provided behind the pulling roller 8, which deflects the horizontal paper web 7 vertically downwards.
  • the paper web 7 wraps around a tensioning roller 52 designed as a dancer roller and is guided vertically upwards.
  • a second paper web guide roller 53 is arranged, which deflects the paper web 17 horizontally to the right in the direction of the take-up rollers 2, 3.
  • the dancer roller 52 is rotatably mounted on a left end 57 of two horizontally arranged pivot levers 56.
  • a right end 54 of the pivot lever 56 is pivotally mounted on the side frames 10 of the feed mechanism 1 so as to be pivotable by an angle ⁇ .
  • a piston rod 58 is articulated with its first end 59 to the pivot lever 56 in the middle of the pivot lever 56.
  • a second end 60 is fixedly connected to a membrane 61, which is attached with its circumference 62 in a sealing manner to an inner wall 63 of a cylinder 64.
  • a space 66 formed from cylinder 64 and membrane 61 is connected to a pressure vessel 68 via a pressure line 67.
  • the pressure vessel 68 acts on the space 66 with a constant pressure p O. In order to be able to adjust the pressure p O to different tensile stresses, the pressure vessel 68 is connected to a pressure source 70 via an adjustable digital valve 69.
  • a cover plate 71 is fastened to the pivot levers 56 and can be inserted into the receiving area of an analog light barrier 72.
  • the light barrier 72 generates an electrical voltage signal U ⁇ which is proportional to the swivel angle ⁇ .
  • the voltage signal U ⁇ is fed to the control device 48.
  • the control device 48 has a number of control systems which are combined in five blocks A, B, C, D, E. Blocks A, B, C are connected in parallel. The block D is connected in series with the two blocks B, C. The outputs of block A, D are multiplicatively linked in block E. An output signal U E of block E is fed to the power driver 47 of the control motor 46.
  • the uniformity of the web tension is determined exclusively by the tensioning roller 52 designed as a dancer roller.
  • the control device 48 takes on the task of quickly returning the dancer roller 52 deflected to compensate for a web tension disturbance to a predetermined target position.
  • the desired position of the swivel lever 56 can also be arranged in any other position (eg vertically).
  • the dancer roller 52 wrapped in the paper web is returned to a desired position by a corresponding change in the speed of the pull roller 8.
  • the regulating device 48 first determines the setting direction for the stepless adjusting disk gear 39 from the dancer position and generates an output voltage U E from a voltage U ⁇ proportional to the dancer roller position.
  • This different evaluation means that the dancer roller 52 strives for its target position asymptotically stable with the same disturbance.
  • Block A contains three control loop elements 76, 77, 78.
  • the control loop elements 76, 77 are connected in parallel to one another and positively linked to one another by means of an addition point 79.
  • the control loop element 78 is a P system and is connected in series with the control loop elements 76, 77 after the addition point 79.
  • the control circuit element 76 is a PT 1 system and has the function of filtering out an adjustable frequency spectrum, ie to evaluate low-frequency components of long-term disturbances more strongly in the longer term.
  • the control loop element 77 is a P system with an amplifier function. Block A thus generates a low-frequency voltage signal U A which is proportional to the deviation of the dancer position from a predetermined desired position.
  • the block B contains four control circuit elements 81 to 84.
  • the control circuit element 81 is a PT 1 system for suppressing high-frequency interference, which, after an addition point 86, is followed by the control circuit element 82 designed as a P system with the control circuit element 83 designed as an I system in a negative feedback loop .
  • the control loop elements 82, 83 are used to determine the derivative, which is required to recognize the speed of the dancer roller 52.
  • the control loop element 84 is arranged behind the control loop element 82 and has the function of a non-linear two-point controller which evaluates an output signal of the control loop element 82 with a positive or negative factor depending on the direction of movement of the dancer roller 52. The evaluation with a positive factor takes place with a direction of movement of the dancer roller 52 upwards with a negative factor with a direction of movement downward, the direction of movement being seen absolutely, regardless of the desired position.
  • the block C contains two series-connected control circuit elements 88, 89.
  • the control circuit element 88 is a PT 1 system for suppressing high-frequency interference.
  • the control circuit element 89 is a non-linear two-point controller for sign recognition, ie for determining the actual position of the dancer roller 52 and a consequent evaluation of the voltage signal U ⁇ with a positive (e.g. +1) or negative (e.g. -1) Factor.
  • the evaluation with a positive factor takes place e.g. B. when the dancer roller 52 is deflected upward, with a negative factor when the dancer roller 52 is deflected downward.
  • the block D contains a detection logic consisting of the elements 93, 94, 96, which links the output signals U B and U C of the blocks C, D together.
  • the link 93 is a decision gate (and gate) with "and" characteristics, ie if both input signals U B and U C are positive, the linked output signal U93 is positive. Is one or both input signals U B , U C negative, the linked output signal U93 is negative.
  • the link 94 is a decision gate with the following "negative and" characteristic: If one or both input signals U B , U C are positive, the output signal U ist is negative. Are both input signals U B ; U C negative, the output signal U94 is positive.
  • the element 96 is a decision gate (or gate) with "or" characteristic, ie if one of the two output signals U93; U94, which are at the same time the input signals for the element 96, are positive, the linked output signal U96 is also positive. Are both signals U93, U94 negative, the output signal U96 is negative.
  • the output signal U96 is the input signal for a control circuit element 98.
  • the block E forms from the outputs U A of the block A and U D of the block D a multiplicative voltage signal U E , which is fed to a controlled system 99, consisting of a power driver 47, reversibly drivable motor 46, dancer roller 52 and light barrier 72.
  • this controlled system 99 represents a double integrator system.
