Definitions

  • the invention relates to a device for dividing a moving material web in the transport direction into several benefits. Such devices are found both in the production of material webs (eg film extrusion lines) and in the further processing of webs of material (eg printing presses).
  • An apparatus for dividing a moving web of material in the transport direction into a plurality of uses typically comprises a slitter and a winder.
  • a slitter and a winder.
  • EP 2 703 326 A1 also known as a spreader roll unit.
  • the process parameters on the slitter (in particular the cutting positions), on the spreader roll unit and on the winder are set by the operator of the plant in question.
  • the adjustment of the entire process parameters is time-consuming and due to the different influencing variables also error-prone.
  • the object of the invention is therefore to provide a device of the type mentioned, whose process parameters are set as quickly and reliably as possible.
  • a device is provided with a longitudinal cutter which comprises at least one knife which is electronically adjustable transversely to the transport direction by means of an adjusting device and with which a longitudinal section in the transport direction can be produced on the moving material web, with a camera system with which the position of the Longitudinal section can be detected and which is adapted to output a position signal on the position of the longitudinal section, and with a control unit, with which the actuating device in response to the position signal and in response to a predetermined actual position can be controlled.
  • the longitudinal cutter is followed in the transport direction by a spreader roller unit for fanning out the benefits.
  • the fanning effect causes the individual benefits to be separated first and then parallel again, so that there is a gap between the individual benefits that facilitates further processing.
  • the spreader roller unit has a first control input for adjusting the fanning by the control unit.
  • the adjustment of the distance of the individual benefits for example, via a control panel.
  • the spreader roller unit is followed by a winder for winding up the utility.
  • the winder preferably has a second control input for setting the winding parameters by the control unit. This can also be done the setting of the winding parameters, for example via a control panel.
  • the camera system comprises a matrix camera which is suitable for detecting a plurality of states of the moving material web and forwarding it to the control unit.
  • the matrix camera can be a high-resolution camera. Due to the high resolution, a downstream image processing is able to detect the different areas in front of and behind the slitter and to analyze the states. Additionally or alternatively, it is also possible that the matrix camera is moved with a positioning system respectively to that position of the moving material web whose state is to be detected. Finally, it is also conceivable that multiple matrix cameras are used, so that different areas can be detected simultaneously. In any case, the use of the camera system allows a closed loop to set the respective process parameters on the slitter, on the spreader roll unit and on the winder.
  • the moving material web 101 is fed in the transport direction A to a slitter 111 which comprises two knives 103 and 104 which divide the material web 101 into the wicks 112, 113 and 114.
  • the knives 103 and 104 are displaceably guided on a stationary traverse 102 and can be adjusted electronically on the traverse 102 with a positioning device, not shown in greater detail.
  • the spreader roll unit comprises the two spreader rolls 105 and 106 which guide the dies 112, 113 and 114 in the manner shown first apart and then parallel again. For electronic adjustment of this fanning, the spreader rollers 105 and 106 on a first control input not shown in detail.
  • the winder 116 has a second control input not shown in detail, with which the individual winding parameters (winding speed, tension of the material web or the individual benefits, etc.) can be set electronically.
  • a camera 108 is mounted, which is guided on a cross member 107 transversely to the transport direction A slidably.
  • the traverse 107 is in turn guided displaceably on the stationary rails 109 and 110 in the transport direction A, so that as a result the camera 108 can approach each point of the device shown.
  • the camera system 117 due to the displaceably guided traverse 107 and the stationary rails 109 and 110, has its own coordinate system which can serve as a reference coordinate system for setting the various process parameters of the apparatus shown.
  • the camera 108 successively detects the actual positions of the longitudinal sections and outputs corresponding position signals to the control unit.
  • the position signals can be obtained, for example, by image processing in that a corresponding software compares the actual cutting positions with the predetermined cutting positions on the basis of a reference image.
  • the control unit in turn controls the adjusting device such that the moving material web is divided exactly at the desired positions. In this way, therefore, a closed loop for accurate positioning of the knives 103 and 104 is made.
  • control unit Due to the input cutting positions as well as the material properties of the moving material web 101, the control unit also calculates the optimal fanning of the spreader roller unit 115 and the optimal winding parameters of the winder 116 and passes these parameters to the first control input of the spreader roller unit 115 and the second control input of the winder 116 further.
  • the actual states of the parameters on the spreader roller unit 115 and on the winder 116 are in turn detected by the camera 108 and forwarded to the control unit, so that a closed loop also arises with regard to the parameters of the spreader roller unit 115 and the parameters of the winder 116.
