Definitions

  • the invention relates to a method for processing a moving web with a web processing process and a upstream web guiding according to the preamble of claim 1. Furthermore, the invention relates to an apparatus for performing this method according to the preamble of claim 8.
  • From the EP 05 024 169 A is a device for grooving or cutting a moving web, in particular in a corrugated web known.
  • the riller or the cutting device is preceded by a web guide, which guides the web running transversely to its direction. This arrangement has been well proven in practice and forms the starting point of the present invention.
  • the invention has for its object to provide a method and an apparatus for performing this method of the type mentioned, wherein the quality of the web processing process to be improved.
  • a moving web is subjected to a web processing process.
  • This web processing process changes the web in and of itself any way.
  • the processing of the running web can be made sufficiently accurate position, the web processing process upstream web guiding, which affects the course of the web. In this way it is ensured that the web is fed correctly to the web processing process.
  • a guide criterion of the web is inventively detected after the web processing process.
  • This guiding criterion may be an edge position of the material web, but alternatively it is also intended to determine any other guiding criterion.
  • This guiding criterion acts on the web guiding control, which is arranged upstream of the web path processing process.
  • the web guiding is therefore designed in two stages, since on the one hand the web run before the web processing process and on the other hand, the guiding criterion is regulated by the web processing process.
  • the two-step regulation results in an advantageous manner, a rapid response to disturbances in the web run as a result of external influences as well as in offset gespliceten webs, on the other hand, however, a balancing of the determined after the web processing process leadership criterion. Influences of the material web processing process on the guiding criterion are corrected in this way, resulting in a high processing quality of the web processing process.
  • the guiding criterion can be determined spatially only significantly after the web guiding, the regulation of the guiding criterion is usually slow, so that in this way rapid changes in the web run can not be compensated sufficiently quickly by external influences. For this purpose, however, the relatively fast web guiding becomes effective, which does not take into account the guiding criterion.
  • the guiding criterion is not only influenced by the web processing process, but rather directly indicates the result of the web processing process. In this way, there is a direct monitoring and control of the web processing process, whereby its quality can be increased accordingly.
  • it is not technically possible to detect the guiding criterion before the material web processing process since the guiding criterion is defined such that the guiding criterion does not even exist there.
  • the two-stage control used has a particularly advantageous effect on the control behavior of the web.
  • the method according to the invention has proved to be advantageous in particular for the web processing processes mentioned in claim 3.
  • the print image on the one hand must be aligned exactly to the web, and on the other hand, the various printed images must also fit exactly one above the other.
  • the printing cylinders are usually rigidly mounted, the web must run correctly on the press.
  • the guiding criterion is preferably the position of the printed image within the web, which is the same after the printing of the same can be detected.
  • the position of the cutting edge within the web in question, which is produced only in the cutting process comes as a guiding criterion.
  • predetermined bending points are produced in the web, at which it can be folded, for example, later.
  • These bending lines must be aligned exactly with an already applied to the web printed image, so that the guiding criterion in this case is the relative position of a bending line to the printed image.
  • this is passed over inclined or curved rollers to the weft threads of the fabric vertically to align the web direction of travel. This results in harmful lateral forces on the web, which lead to a run of the same.
  • the two-stage control according to the invention can here effectively guide the web without requiring an additional device for influencing the web run immediately after the straightening machine.
  • An adhesive application can take place in a predetermined pattern.
  • the distance between the same and different feature categories can be measured, for example between two printed images or between a printed image and a marginal edge.
  • the location of a printed image is particularly important in the packaging sector of considerable importance. In the case of textile webs with a very large pattern, the position of the printed image within the web, in particular the repeat, can also be important.
  • the location of a marginal edge is often of particular importance for guiding a web. If the material web processing process has a longitudinal cutting machine, the special problem arises that the marginal edge to be scanned only arises in the process.
  • the guiding criterion may depend on the relative distance between features of the fabric web top and bottom.
  • the leadership criterion the relative distances of all the above features come into question, the leadership criterion is determined in detail according to the quality specifications.
  • the particular advantage of the method according to the invention lies in the fact that the guiding criterion is detected directly regardless of its complexity and in particular regardless of its formation within the entire web processing and returned to the web guiding.
  • a simple realization of the described two-stage web guiding system results according to claim 5, characterized in that at least one of the guiding criteria influences the target value of the web guiding.
  • the setpoint value of the web guiding control is therefore assigned an offset so far that the currently determined error is corrected again.
  • the web processing device partially does not work correctly. For example, a blunt knife of a web cutting device, the web no longer complete cut so that there is no proper cutting edge.
  • the guiding criterion includes the direct result of the material web processing device, ie, the cut material web edge in the example mentioned, a considerable jump would result for the guiding criterion, since instead of the current cutting edge, the original material web edge suddenly flows into the guiding criterion. However, this leads to a significant web displacement and thus a considerable committee of web production.
  • the fast web guiding remains fully intact, so that disturbing influences on the web are still compensated. A shutdown of the entire production line of the web is thus not required. In principle, it is also intended to store the exceeding or falling below the tolerance threshold of the guiding criterion in order to be able to easily sort out the section of the material web which is affected by this later.
  • the guiding criterion influences the web processing process.
  • a cutting blade or riller could be displaceable transversely to the direction of web travel.
  • printing cylinders conceivable, which are housed several times in a press in order to realize a register control. In this way, the web processing process can be significantly refined.
  • the device according to claim 8 serves to carry out the method according to one of claims 1 to 7.
  • This device has at least one web running control of the web influencing web guiding device, which can be realized in a variety of ways.
  • This web guiding device may comprise, for example, at least one roller partially wrapped by the web, which is pivotable about a fixed axis. In this way, this roller can exert a directed transversely to the web direction of travel force on the web.
  • the web guiding device may also have a so-called rotating frame, which is formed by a pivotable block in which a plurality of guide rollers are mounted for the web. It is also conceivable that the web guiding device comprises one or more rollers which are pivotally mounted and press against the web.
  • the web guiding device also has a controller, which receives actual value signals of a first sensor.
  • This first sensor detects the position of the web transversely to its direction, so that in this way a web guide is created.
  • the first sensor is arranged downstream of the web guiding device to a closed loop to achieve.
  • the first sensor is followed by at least one web processing device, which processes the web in some way.
  • the web processing device is followed by at least one second sensor, which detects a guiding criterion of the web. This guiding criterion is in operative connection with the aforementioned web guiding device, so that at least two control loops are provided.
  • the first control loop extends over the web guiding device and the downstream first sensor and implements a web travel control known per se.
  • the second control loop extends over the web guiding device, the web processing process and the at least one second sensor and thus enables a regulation of the guiding criterion.
  • the guiding criterion can be influenced by the web processing device or generated by them.
  • the at least one second sensor is formed by a camera which is directed against the web.
  • a camera With a camera, a wide variety of management criteria can be obtained through downstream image processing.
  • any elements of a printed image, the three-dimensional structure of the web, the edge or cut line layer or the like can be scanned by the camera.
  • the calculation of the specific leadership criterion can be done by a downstream software application, so that the device is very flexible and universally applicable overall.
  • the at least one second sensor monitors at least one feature of the web, which has been created by the web processing device.
  • the immediate result of the web processing device is evaluated as part of the management criterion, so that there is a perfect monitoring and control of the web processing device in this way.
  • the at least one first sensor is preferably provided near the web guide device, so that it can detect changes in the web run due to the web guiding device with a short reaction time and thus can quickly compensate.
  • the at least one second sensor Due to the system, the at least one second sensor has a considerably greater reaction time, since the material web first has to pass through the entire web-processing device before changes in the guiding criterion can be deducted by at least one second sensor.
  • the web guiding device has at least one pivotable and looped by the web control roll.
  • the pivotal position of this roller rule is influenced by at least one control device, which is part of the web guiding device.
  • this control device then act on the one hand, the downstream at least one first sensor and on the other hand, the web processing process downstream at least one second sensor.
  • the single figure shows a device 1 for processing the running web 2.
  • the web 2 could be a paper, foil, cardboard, corrugated, textile, metal or a combination of these substances.
  • the web 2 is a cardboard web. It has a longitudinal embossing edge 2 ', which serves as a predetermined bending line. The web 2 is guided over rollers 3.
  • the device 1 has a web guiding device 4.
  • This web guiding device 4 is formed by a web influencing device 5, an actuator 6 and a controller 8.
  • the web influencing device 5 is formed in the illustrated embodiment as pivotable about a pivot axis 7 pivotal frame 9, on which two control rollers 10 are pivotally supported. At every the rule rollers 10, the web 2 is deflected by 90 °.
  • the entire rotating frame 9 is held rotatably by means of the servomotor 6.
  • the servomotor 6 engages on a not shown gear on the rotating frame 9.
  • the rotating frame 9 is each a roller 3 upstream and downstream, which serve as a fixed rollers.
  • the web guiding device 4 is in operative connection with a first sensor 12, which is designed by way of example only as a camera.
  • the first sensor 12 transmits its acquired image data to an image evaluation device 13, which determines, for example, the position of a web edge 14 of the moving web 2.
  • the first sensor 12 could also detect the web edge 14 directly, for example by means of a light barrier, pneumatically, inductively or mechanically. This position is transmitted via a signal path 15 as an actual value to the controller 8.
  • the sensor 12 is followed by a web processing device 16, which is formed by at least two guide rollers 3 and a cylinder 17.
  • the processing device 16 can be designed differently, depending on which specific machining process is to be applied. In particular, it is thought to form the cylinder 17 as a printing cylinder to print the web 2 with continuous images or a continuous pattern. Alternatively or additionally, the web processing device 16 may also have cutting knives 18 and / or rillers 19 which separate or scrape the material web 2 along its web running direction 20. There are also any Other applications for processing the web 2 conceivable.
  • the web processing device 16 are arranged downstream of two second sensors 21 in the form of a respective camera, which scan the web 2 from above and below.
  • the second sensors 21 detect the web 2 after being processed by the web processing device 16 and transmit the obtained image data to a further image evaluating device 22.
  • this image evaluation device 22 determines a guiding criterion F, which corresponds, for example, to the distance of the flat-cut web edge 14 'from the embossing edge 2'.
  • This guiding criterion F is supplied to a further controller 24 via a signal path 23.
  • This controller 24 is on the output side via a signal path 25 with the controller 8 of the web guiding device 4 in operative connection and passes this a target value. In this way, two nested control loops, wherein the inner forms a simple web guiding, while the outer corrects a more or less complicated guiding criterion F.
  • the output signal of the image evaluation device 22 is also operatively connected via the signal path 23 to a comparator 26, which compares this output signal with one or two threshold values. In this way, a plausibility check of the evaluated leadership criterion F performed. On the basis of this plausibility check, the comparator 26 decides whether the guiding criterion F has been correctly recorded. In this case, the guiding criterion F is processed directly in the controller 24, so that the outer control loop is closed.
  • the controller 24 is blocked via a holding input 27, so that the output signal of the controller 24 and thus the setpoint value of the controller 8 of the web guiding device 4 is kept constant , In this operating state, the outer control loop for the guide criterion F is interrupted, but the inner loop for the web guiding control with the measured value of the first sensor 12 as a controlled variable remains in function.
