- the "film web” can either be a single-layer film web or a tubular film web, wherein the hose can be separated or left tubular.
- the film web may be single-layered or multi-layered, in particular, therefore, it is also envisaged that a plurality of extruders be provided can.
- winder not only a winder may be provided, but also a plurality of winders.
- the "machine direction” is the designated path of the film, starting from the extrusion at the die to the winder, and the machine direction varies because it passes around a plurality of rolls and, if necessary, turner bars.
- Defects in the "flatness" are in particular foil sags in the tension-free state and / or a sheet travel of the film web.Thus, there may be films with an ideally constant thickness, which nevertheless have a flatness error, and there may be films with a thickness deviation, which nevertheless an ideal Have flatness. The cause of a flatness error lies in locally different lengths of the film web.
- the first aspect of the invention therefore provides - in simple terms - to regulate a film production plant in any case even after the flatness.
- the system has a second control loop, with a sensor which is adapted to detect a measure of a thickness profile deviation, and with a controller, which is adapted to an actuator on the basis of the degree of thickness profile deviation and to improve to control the thickness profile deviation.
- the senor and / or the controller and / or the actuator may be the same as those of the control loop according to the first aspect of the invention. Only linguistically they are referred to here as "second (s).” It is considered by the inventor to be ideal, if such a regulation is provided according to the thickness profile, and additionally the proposed regulation according to the flatness.
- the regulation according to the thickness profile should influence the thickness profile as well as possible, and the control according to the flatness error should influence the flatness as well as possible.
- the controller can be data-connected to the actuator.
- the actuator is electronically controlled, and a computing unit on the actuator evaluates the data and thus executes the control.
- the controller may be motor current connected to the actuator.
- the actuator is electrically controlled, and the controller executes the control.
- actuator for example a hydraulic drive.
- the actuator is adapted to drive a heating means and / or a Leksdehnein- direction on the way from the nozzle to the winder.
- the influencing means for the film web controlled by the actuator are suitable for taking direct influence on the properties determining the flatness of the film web during production.
- the flatness of the film web on the winder can thereby be kept as ideal as possible during the production process, namely with appropriate adjustment of the control loop without human intervention. Rather, the system may be able to automatically keep the flatness ideal.
- a concrete embodiment of the invention provides that the sensor is adapted to detect a run-off edge of the film web on the guide roller, wherein the sensor is data-connected to the controller.
- the "run-off edge" of the film web at that deflecting roller which the sensor is designed to detect is that line along which the film is released from the surface of the deflecting roller.
- the run-off edge and its detection are described in detail in WO 2007/107147 A1 ,
- the controller evaluates the deviations of the trailing edge from an ideal, straight line, which is parallel to the Umlenkwalzenachse, as a measure of a flatness error in the moving film web.
- the controller therefore influences the actuator and controls it in such a way that the spot identified as defective is corrected.
- the location in the circumference of the film web or the position in the width of the film web can therefore be heated, for example, with a heating means, which leads to greater extrusion, and / or the body can be stretched or stretched more extensively in a longitudinal stretching device, or other measures can be taken can be taken, for example, can be influenced on the cooling, on the geometry of an outlet lip, etc.
- the plant is a blown film plant, wherein the nozzle is an annular nozzle and on the way from the annular nozzle to the winder a flattening and a deduction and optionally reversing are provided.
- the nozzle is an annular nozzle and on the way from the annular nozzle to the winder a flattening and a deduction and optionally reversing are provided.
- the sensor is arranged in the path from the annular nozzle to the winder beyond the flatness, in particular beyond the trigger, preferably even on one of the last three or two deflection rollers in front of the winder, particularly preferably on the last deflection roller in front of the winder, where the deflection roller may even already belong to the winder.
- a particularly preferred embodiment of the invention provides that a longitudinal expansion device is arranged on the way from the annular nozzle to the winder between the trigger and the sensor, or a longitudinal expansion device is arranged on the way from the annular nozzle to the winder between the sensor and the winder.
- a longitudinal stretching device to a plant unit, which can eliminate flatness error by longitudinal stretching, including the temperature of the film web, especially in the trigger, is increased to a defined value and the film web is subjected to a slight elongation, preferably between 1% and 4% ,
- the system is designed as a flat film system, wherein the nozzle is a slot die and on the way from the slot die to the winder first a cooling roller, namely the most "chill roll” called cooling roller is arranged, the slot die on the Chill roller extruded.
- a support means for introducing an electrostatic charge between the film web and the guide roller is provided so that when - switched charging device during operation of the system, the trailing edge of the film web from the guide roller moves downwards and differentiated in height.
- a brush may be provided for introducing an electrostatic charge, or an electrical connection may apply a single pole voltage to the surface of the roller.
- an electrical connection may apply a single pole voltage to the surface of the roller.
- the deflecting roller which is used to implement the present invention is disposed at a ground station, then there is a particularly easy access to the mechanical and electrical devices of the invention. It is also particularly easy to place the sensor in the immediate vicinity in front of the winder.
- the deflection roller in the machine direction is the last deflection roller in front of the winder.
- the stated object solves a method for operating a system for producing a film web by means of a nozzle from a supplied from an extruder plastic melt and for winding the film web to a winding on a winder, the system on the film web her way along a machine direction from the nozzle to the winder to guide a guide roller and finally wound on the winder to wind the winding, the system comprises a control loop with a controller, a sensor and an actuator, and wherein the sensor is a measure of the The position is recorded and the controller controls the actuator based on the measure of the flatness and to improve the flatness.
- the sensor is preferably set up to detect a run-off edge of the film web on the deflection roll, for which the controller receives data via a data connection from the sensor, carries out a comparison with these and, depending on the results of the adjustment, with desired values or with previous actual values activates the actuator via a data link to set a heating means and / or a longitudinal stretching device on the way from the nozzle to the winder.
- the single figure schematically shows the structure of a blown film plant.
- the blown film system 1 in the figure essentially consists of three extruders 2, which feed a blow head 3 with plastic melt, which has been produced in the extruders 2 from plastic granules.
- the blowing head 3 blows in a direction of extrusion 4, here vertically upward, from a Ringschlitzdüse a film tube 5. After a flattening 6 of the film tube 5 passes through a pair of delivery rollers 7 (not shown in detail).
- the film tube 5 runs as a flattened endless film web 8 two layers in the machine direction 9 to a winder 10th
- the film web 8 On the way from the trigger, defined by the take-off roller pair 7, to the winder 10, the film web 8 first passes through a longitudinal stretching device 11 according to the patent application WO 2014/023282 A1 of the present Applicant.
- an optically delimited inspection space 15 is passed through.
- the inspection chamber 15 is located on the circumferential side of the guide roller 14, a light 16, which is directed to the guide roller 14.
- the film web 8 runs around the deflection roller 14, wherein the film web 8 at a run-off edge 17 (not visible in detail) again dissolves from the surface of the guide roller 14 and continues to run in the machine direction 9.
- a camera 18 is directed, here a CCD camera or other digital image-relaying camera.
- the image data of the camera 18 are passed via a first data connection 19 to a controller in a central control and regulation unit 20.
- the controller compares the measured values of the camera 18 with predefined setpoint values, or with the previously determined actual values, the controller evaluating deviations of the outflow edge 17 from an ideal straight line from the controller so that the controller draws conclusions about detections in the film.
- the controller As soon as the controller detects deviations, it controls a temperature control 22 and / or a mechanical drive 23 via a second data connection 21. As a result, the longitudinal stretching device 1 1 engages mechanically on the film web 8. As a result, the thick points previously detected by the camera 18 in the film web 8 are reduced or even completely eliminated with suitable control. Should this result in other thick places, they are automatically taken up again by the camera 18 as a result of the varying run-off edge 17, recognized by the controller in the control / regulating unit as such and again via a controlling intervention on the second Data connection 21 reduced or eliminated.
- the plant can thereby come to an ideal production in an iteration.
- the duration of each iteration is only the duration to reach a new steady state and the transit time along the machine direction 9 from the exit from the longitudinal expansion device 11 until the discharge from the deflection roller 14.
