Definitions
- the invention relates to methods and a device for regulating the web tension of a multi-web system according to the preamble of claims 1, 18, 21 and 22 respectively.
- EP 08 37 825 A2 discloses a method for regulating the web tension of a plurality of webs, the web tension levels relative to one another being regulated on the basis of the respective web tension of a plurality of webs using a control system based on fuzzy logic.
- DE 100 27471 A1 discloses a method for regulating web tensions in multi-web operation, wherein first absolute and relative tensions of the webs to one another are set at the funnel inlet. This is preferably done with the respective feed mechanism.
- the invention has for its object to provide methods and an apparatus for controlling the web tension of a multi-web system.
- the invention provides a system for the self-adjusting control of the web tension for multi-web processing machines, in particular rotary printing machines. Due to its closed regulation, it is an essential further development compared to web tension control systems currently used in rotary printing presses.
- the system is advantageous for triple or double-width printing machines.
- the control concept based on the fuzzy logic makes an innovative contribution to more production reliability and quality consistency in a production that is increasingly geared towards less waste and less manual intervention from a cost perspective.
- the control supports the operator when starting up the machine, relieves him of the web tension control during production and contributes to more stability in all phases of production.
- a paper web On the way through the rotary printing machine from the reel changer to the infeed unit, the printing units and the superstructure to the folder, a paper web has different tension states (or tension relief or tension profile), with the type of paper used (manufacturer, grammage, paper type), the repeated application of printing ink and, if necessary, dampening water (using the offset process), the driven tension elements (feed mechanism with or without dancer roller, tension roller, funnel inlet roller) and changes in speed influence the real tension profile of the paper web within the machine. Controlling a constant web tension in multi-web operation is even more demanding and complex.
- the relative tension of the individual paper webs to one another is important for optimal web running and printing conditions.
- Web tension control systems based on PID controllers have already been implemented on modern newspaper offset presses in the area of reel changers and feeders with a dancer roller.
- the downstream traction devices in the machine after the printing units and in the hopper inlet
- neighboring units other reel changers and infeed units
- the coupling of the tension elements in accordance with the production situation into a comprehensive, self-regulating web tensioning system is therefore of particular advantage.
- both an optimal tension profile of each individual paper web within the machine and optimized tension profiles of the individual paper webs with respect to one another are to be ensured in order to increase the starting safety (avoidance of paper tears) and to increase the net production output (through less downtimes due to malfunctions) ) to achieve a uniform print quality (fewer register differences) and to improve the running reliability in multi-web operation.
- the software sets the optimal tension level within a paper web based on the fuzzy logic, depending on the situation at the hopper inlet and the respective paper profiles, and optimally aligns the webs with one another.
- the paper profiles i.e. H.
- the information available e.g. stress-strain characteristics
- the information available e.g. stress-strain characteristics
- Expert knowledge is stored in the system for quick definition of the setting logic.
- the intelligent control system directly controls the actually measured tension values of the paper webs in the processing machine and not indirectly based on strain measurement and control based on motor moments. This brings advantages in terms of efficiency as well as the positive effect on waste, production costs and operator ergonomics.
- FIG. 1 shows a printing press with a plurality of webs
- Fig. 3 is a schematic representation of the control of the printing press from Fig. 1;
- FIG. 7 shows a flow chart of the multi-lane-related control process.
- Fig. 1 shows a path of several, at least two webs B1; B2; B3; B4, e.g. B. Material web B1; B2; B3; B4, e.g. B. paper web B1; B2; B3; B4 by one Processing machine, in particular printing machine, with aggregates schematically shown which significantly influence the web tension:
- the train B1; B2; B3; B4, exemplified on the track B1 is supplied by a supply 01, z. B. a role change 01, fed and passed through at least one pulling device (or braking device) 02 for conveying and setting a web tension, for. B. a feed unit 02 before a processing stage 03, z. B. passes through at least one printing unit 03 with one or more printing units.
- the feed mechanism 02 can simultaneously represent an actuator 02 for setting the voltage in front of the printing unit 03. After a last printing point assigned to web B1, it passes through a measuring point 04 (nDE: after printing unit 03) to determine the web tension and then an actuator 05 influencing the web tension, for example a drawing roller 05 or roller / drawing group 05.
- Turning bars and longitudinal cutting devices can be arranged, by means of which either uncut webs B1 can be turned or plunged, or webs B1 can first be cut and then turned or plunged.
- harp 07 a plurality of deflection rollers assigned to several webs B1; B2; B3; B4 or partial webs
- Measuring point 06 vTE: before funnel inlet
- the measuring point 04 “after the printing unit” thus means a measuring point 04 in front of the tension element 05 following the printing unit 03 or at least in front of a cutting and / or turning device that may be present.
- the web B1 (or its partial webs) are put together merged with other webs B2; B3; B4 (or their partial webs) to form one or more strands 13, another actuator 08 influencing the web tension passes, a pull roller 08 or roller / pull group 08, e.g. a so-called funnel inlet roller 08, before they are folded lengthways, for example, by one or more funnels 09.
- the measuring point 06 “before the funnel inlet or harp” thus means a measuring point 06 for the individual web or partial web before combining webs or partial webs on the web Hopper inlet roller 08 (or another upstream roller assigned to several webs) and after the tension element 05 or, if present, after a cutting and / or turning device. If the product is not rewound, the webs pass through B1; B2; B3; B4 (or partial webs) in the strand 13 a further actuator 10 influencing the web tension, a further tension roller 10 or roller / tension group 10, e.g. B. folding rollers 10, and are folded at least once transversely in at least one folder 11.
- the above-mentioned infeed unit 02 has an actuator 16 which influences the web tension, a pull roller 16 or roller / pull group 16 or dancer roller 16 and, if appropriate, a separate measuring point 14 for determining the web tension (vDE: in front of printing unit 03).
- the actuator 16 and the measuring point 14 can also be arranged between the roll change 01 and the printing unit 03 without being combined to form a feed mechanism 02.
- the separate measuring point 14 can be omitted if there is already adequate information about the voltage present via the actuator 16, for example as an actuator 16 which can be actuated by means of pressure medium.
- webs B1; B2; B3; B4 are fed from printing units 03 arranged on different sides, wherein the funnel structure can have a plurality of funnels 09 next to and / or one below the other, and a plurality of webs B1; B2; B3; B4 strands 13 formed can be guided on more than one folder 11.
- Lanes B1; B2; B3; B4 do not each pass through a printing unit 03 in the manner shown schematically, but can e.g. B. after passing through a part of a printing unit 03 out of this and either the superstructure or another printing unit 03 for further processing.
- Fig. 1 are indicated by arrows through the measuring points 04; 06; 14 obtained signals S1.1; S1.2; S1.3 of the train B1, S2.1; S2.2; S2.3 of the web B2 etc. indicated.
- a signal S1.0; S2.0; S3.0; S4.0 dashed lines from a measuring point not designated.
- Next are the default values for the actuators 16; 05; as signals S1.11; S1.12 for train B1, S2.11; S2.12 shown for the course B2 etc. with arrows.
- the signal Sx.11 represents, for example, a default value (target value) for the web tension in the infeed unit 02
- the signal Sx.12 represents a default value (target value) for the advance of the tension roller 05.
- the signals SO.13; SO.14 set the default values (setpoints), e.g. B. the advance for the control elements 08 and 10.
- a possibly present default value (setpoint) for the web tension in the area of the reel changer 02 is designated with S1.10 for web B1, with S2.10 for web B2 etc. ,
- the printing press from FIG. 1 has a control system 17, the concept of which is initially explained in principle with reference to FIG. 2, and in FIG. 3 with a direct reference for controlling the web tension of a plurality of webs B1; B2; B3; B4 from FIG. 1, at least several webs B1 running together on at least one hopper inlet roller 08; B2; B3; B4 (or partial webs) is shown.
- the control system 17 has two different controller types 18 and 19 with two different subtasks (control processes). These two “types” of controllers 18 and 19 can be spatially separated from one another as different hardware components, as different software programs communicating with one another, or as two processes or subroutines or subroutines in one software program. Unless explicitly stated otherwise, In the following, the terms controller 18; 19 and control processes 18; 19 are given the same reference numerals and are to be understood for all of the above and other suitable ways of implementing them. As shown in FIG. 2, the control system has several (here two ) Controller 18.1; 18.2, which each actual values obtained from a respective sub-process and generate one or more manipulated variables for the sub-process under consideration based on their implemented logic.
- the controller 18 is the controller 19, which receives actual values from the sub-processes, based on its implemented logic default values for the subordinate controller 18.1; 18.2 and, if necessary, outputs control variables directed to the overall process. There is no mutual interaction or communication between the controllers 18 and 19. They can work at the same time, but in principle they work independently of one another, although they sometimes consider the same process values (actual values) and the control process 19 generates specifications (setpoint specifications) for the control processes 18 ,
- FIG. 2 Also shown in FIG. 2 are memory devices 21, of which start values are sent to the controllers 18; 19 can be read.
- the start values are advantageously read from a common memory unit 21.
- the control system 17 receives at least two measured values, namely the measured value S1.2; S2.2; S3.2; S4.2 for the voltages, e.g. B. from measuring point 04 designed as measuring rollers 04, (directly) after the respective printing unit 03 and the measured value S1.3; S2.3; S3.3; S4.3 fed from the respective measuring point 06 before the funnel inlet or the harp 07.
- the control system 17 can also use the signal S1.1; S2.1; S3.1; S4.1 for the voltage are fed before the printing unit 03 (dashed lines).
- the voltage is measured e.g. through from train B1; B2; B3; B4 wrapped measuring rollers.
- the input variables such as B. the measured values S1.3; S2.3 etc. for the tensions (if necessary scaled accordingly) of a path B1 are fuzzyfied, ie as input values for functions defined in sections used, each describing a term (linguistic size range, e.g. large, medium, small).
- the degree to which the input value fulfills the linguistic meaning of the term or, if the value ranges overlap, the degree of fulfillment is obtained as the function value.
- a sharp starting value e.g. B. generates a corresponding signal to an actuator or a new setpoint for an actuator.
- one actuator, another actuator or several actuators can be specified. Which rules are used is determined by the degree of fulfillment of the terms of the input variables.
- An example above with the two input variables (e.g. measured values S1.3; S1.2) and an output variable (e.g. signal S1.12 to an actuator, e.g. roller / train group 05) for e.g. , B. tabulated, held rules could be graphically z. B. represent as a three-dimensional map.
- the “characteristic diagrams” are correspondingly multidimensional.
- the controller 19 does not have to be based on fuzzy logic, but can be designed in a discrete manner, for example as a PID controller 19 However, execution with fuzzy logic is also advantageous here.
- control system 17 has the two different controllers 18 and 19 with two different subtasks, the controller 18 determining the web tension of a single web B1; B2; B3; B4 regulates its course and with regard to limit values, and the controller 19 regulates the tension level, in particular the tension level upstream of the funnel feed roller 08, of the webs B1; B2, B3; B4 sets relative to each other.
- the control system 17 has at least a number of controllers 18 which correspond to the total number of tracks B1; B2; B3; B4 (or partial lanes) corresponds.
- the controllers 18 all have the same architecture or are of the same type and programmed way and are for the four lanes B1; B2; B3; B4 with 18.1; 18.2; 18.3; Designated 18.4.
- the four controllers 18.1; 18.2; 18.3; 18.4 or processes 18.1; 18.2; 18.3; 18.4 is assigned to controller 19 or control process 19.
- the control system 17 is given start values as setpoints, which z. B. provide useful starting points for certain path guides.
- a second requirement of the first subtask may be the gradation shown schematically in FIG. 4 in the voltages at the measuring points 14 (before the printing unit 03), 04 (after the printing unit 03) and 06 (before the funnel inlet or before the Merge).
- the process-related minimum voltages e.g.
- the task of the controller 18.1; 18.2; 18.3; 18.4 or processes 18.1; 18.2; 18.3; 18.4 is thus the tension of the individual web B1; B2; B3; B4 at the funnel inlet, especially on the way there, to be regulated in the basically permitted area and, if necessary, the correct gradation within the path of the individual path B1; B2; B3; To achieve B4.
- the controller 18.1 processes these input variables in the above-mentioned manner by means of fuzzy logic and generates an output signal S1.11, which acts on the actuator 16 of the feed mechanism 02.
- the controller S1.1 can additionally be supplied with the signal S1.1 for measuring the voltage upstream of the printing unit 03 and can also be processed in the logic.
- the controller 18.1 also acts on the actuator 05 behind the printing unit 03, for example with a signal S1.12. B. by determining and specifying suitable advance values.
- a signal S1.12. B. by determining and specifying suitable advance values.
- an improved setting of the voltage curve over the path of the path B1 is possible.
- the control concept takes place z. B. in such a way that it is first attempted by means of the actuator 16 to meet the conditions for the minimum / maximum voltages and at the same time the desired voltage profile. If this is not possible solely by acting on the actuator 16, the actuator 05 is included.
- start values are read in from a memory device 21.
- the sub-process before querying the machine status (in production?) Is part of the initialization of the system.
- the queries are answered with "true” (w) or "false” (f) in the diagrams.
- the connection with the arrow from the lowest node of the process to the node before the query for the machine status makes it clear that it is a process that is continuously run as long as the machine is in production.
- FIG. Change or shift of an assignment diagram shown In a first state of the diagram, a measured value Sm has first values for the weighting of “small” and “medium”. After the assignment functions have been shifted (defined in sections), the measured value Sm is opposed by weights "small” and “medium” which differ therefrom. This change in weighting is now reflected in the overall view of all fuzzy rules and eventually leads to a shift in the target value for the control variable under consideration, e.g. here the manipulated variable S1.11 for the feed mechanism 02.
- the controller 19 or the control process 19 checks whether the tension in front of the harp 07 of the webs B1; B2; B3; B4 are in the desired relationship to each other and regulated accordingly. So z. B. the bottom web B1 coming to lie on the pull roller 08; B2; B3; B4, here path B3, have a higher tension than the one above it, etc.
- the second task is therefore to adjust the tensions of the tracks B1; B2; B3; Grading or aligning B4 to each other in the area of the funnel inlet.
- the basic condition for all lanes is B1; B2; B3; B4: MAX>Si> S 2 ⁇ S 3 >S> MIN if the index shows the order of the paths B1; B2; B3; B4 in the area of the hopper inlet roller 08 from the inside to the outside.
- the tensions of the different paths are z. B. varies in such a way that for all tracks B1; B2; B3; B4 the tension in front of the hopper inlet roller 08 is in the tolerance range (FIG. 4, before the hopper inlet (vTE)).
- the controller 19 in parallel to the controller 18.1; 18.2; 18.3; 18.4 the signals S1.3; S2.3; S3.3; S4.3 of the measured values for the web tension supplied.
- controller 19 or control process 19 is also based on fuzzy logic, by means of which the input variables (signals S1.3; S2.3; S3.3; S4.3) provide default values for controllers 18.1; 18.2; 18.3; 18.4 and signals SO.13 and SO.14 are generated as output variables for the actuators 08 and 10 interacting with the strand 13.
- the actual sub-process for the adjustment of the voltages Sx.3 can be preceded by a sub-process which, as shown, on the basis of the individual measured values Sx.3 checks the total web tension level and, if necessary, via the adjustment (for example the advance) of the funnel infeed roller 08, which raises or lowers the overall level for all webs running over this roller 08.
- the sub-process includes the steps of reading in measured values - checking total web tension level - and depending on the result, calculating and outputting the adjustment of the funnel infeed roller (f) or leaving it as it is (w).
- the controller 19 or control process 19 has no direct influence on that of the individual path B1; B2; B3; Actuators 16 assigned to B4; 05, but based on its map from signals S1.3 to S4.3 gives the controller 18 specifications.
- This specification only relates to the one in front of the funnel roller 08 for each web B1; B2; B3; B4 voltage to be observed, ie a setpoint for the z. B. at the measuring points 06 to be observed.
- These default values are received in the controller 18.x (for example, by changing the position and / or shape of the terms with regard to the input variables during fuzzification) (see above).
- the control of such units by the control system 17 takes place in an advantageous embodiment taking into account a priority.
- B. as described above by the control system 17 in a first priority, the setpoint specification only for the feed unit 02. Are this measure alone the two above.
- the pull roller 05 is acted upon after the printing unit 03. in a third stage it is allowed to influence the funnel inlet roller 08.
- the actuators pull roller 05 or hopper inlet roller 08 are only used if the global web tension over all webs B1; B2; B3; B4 is not correct, or if the adjustment range of the feed mechanism 02, or its actuator 16, is not sufficient for the desired web tension.
- the logic of the control system 17, in particular of the controller 19, can be designed to approach the ideal state as closely as possible to strive for an optimized state. Acceptable limits for the deviation (relative or absolute) can be specified and, if necessary, changed.
- the control system 17 can be designed to issue a warning in the event of a strong deviation from the permissible tension profile (one path) or the gradation (all paths to one another) and, if necessary, to bring the processing machine to a standstill if the deviation is unauthorized.
- control system 17 works with two measuring locations for the tension per path B1 involved; B2; B3; B4, specifically after the printing unit 03 and before the hopper inlet, the action taking place first on the feed unit 02 and possibly in the second step in the area of the pull roller 05.
- the roll changer 01 and the feed mechanism 02 preferably have a closed control system, to which a setpoint is predetermined by the control system 17.
- the pull rollers 05; 08; 10; 16 are from the control system 17 z. B. only controlled with respect to their advance (speed, angular position).
- the feed mechanism 02 has a closed control ("closed loop" control), the setpoint specification by the control system 17, in particular by the controller 18, is reliably adhered to. It acts on the entire web B1; B2; B3; B4 and provides this
- the pull-in means 02 as the actuator 16 has a roller which can be moved against the tensile force of the web B1; B2; B3; B4 and which counteracts a predefinable pressure of the web tensile force by means of pressure medium. In this case there is no separate measuring point 14 required if the correlation between the applied pressure and the resulting web tension is known.
- the pull roller 05 can by changing the advance compared to the paper web speed to the web tension of the current web B1; B2; B3; B4 act and here represents the last possibility in front of the hopper inlet roller 8, a single web B1; B2; B3; To influence B4 in its tension or gradation.
- the funnel inlet roller 08 can by changing the advance compared to the paper web speed on the web tensions of all webs B1; B2; B3; B4 act.
- the folding roller 10 can also by changing the advance compared to the paper web speed to the web tensions of all webs B1; B2; B3; B4 act. It has a direct impact on the cutting register.
- a z. B. Modular structure allows the regulation to be extended to several lanes, for each additional lane B1; B2; B3;
- B4 only has to have a further controller 18, e.g. B. a fuzzy PLC with a program can be added.
- the program of the controller 19, for. B. the master PLC must also be notified that there is another lane B1; B2; B3; Must include B4.
- a web B1; B2; B3; B4 only the software is expanded by a control process 18.x, and the program of the control process 19 is communicated.
- the regulation by the regulators 18 and 19 can run purely sequentially or in terms of time in parallel, but with regard to the voltage to be set in front of the hopper inlet roller 08, e.g. at the measuring points 06, the control is hierarchical and the controller 19 is superior to the controllers 18.
- control system 17 is designed such that a setting found by the control system 17 for a specific configuration of the print job, a web path and / or a specific product can be transferred as default values into the storage device, so that it can be used in the future with the same or a similar one Production situation can be read as starting values.
- the product or production data is taken over from the machine control and / or product planning.
- the adoption as new start values can be triggered, for example, upon the decision of the operating personnel, or can be carried out by the system itself if the control and / or regulating system are designed as a self-learning system with regard to this function.
