Definitions

  • the invention relates to a method for determining a the winding density-related winding parameters of a tape winding process, and an apparatus for performing the method.
  • Tape material made of metal foil or plastic foil becomes too large coils wound up to be shipped to processing plants to become.
  • the winding on a winding core takes place with high speed, tearing air into the wrap becomes.
  • a certain amount of air between the windings of the Wrapping is desirable because it makes the wrap a certain amount Maintains softness and elasticity.
  • a homogeneous and with the desired air inclusion winding can in processed at high speed become. With winding of poor quality, however, the Unwinding speed can be reduced. There is therefore a Need for tape winding processes with a defined winding density to be able to perform.
  • the winding density is the ratio of the actual Weight of the wound material web in the ratio to the theoretically possible full weight of the Wrap without air pockets.
  • the invention has for its object a method and a device for determining a related to the winding density Specify winding parameters to order with simple means to enable a highly accurate determination of the winding parameter.
  • the invention is related to the winding density Winding parameters determined in that one after the other occurring measuring cycles that a selected number of revolutions of the winding core correspond to that wound up Winding length is determined.
  • the two measured values of the winding lengths are then related to each other, taking into account the material thickness of the winding parameters becomes.
  • the winding parameter to be calculated is the winding density or the strength of the between two Wrapped layers of air.
  • the procedure can be carried out with only two measuring devices, from which the one measuring device detects the winding length, while the other comprises the revolutions of the winding core. From the values of the values obtained during successive measuring cycles
  • the desired winding parameters can be calculated from the winding length on condition that the material thickness is known is and remains constant, or with a thickness measuring device is continuously recorded.
  • the invention makes it possible to refer to the winding density Not to determine parameters only at the end of a winding process, but to know already during the winding. this makes possible it to take immediate influence and regulate the parameter to make.
  • the extent of a wound turn of the The extent of the previous turn can be subtracted.
  • the so determined difference in length is a direct measure of the Diameter increase of the winding.
  • the diameter increase is that Sum of material thickness plus air influence.
  • the start diameter and end diameter refer to the start and end of the same winding cycle.
  • the number of revolutions of the winding core that a measuring cycle result is preferably an integer. In this case needs only the zero crossing is detected with each revolution to become.
  • the number of revolutions can be counted by the zero crossing pulses be determined.
  • a measuring cycle consist of exactly 10 revolutions. It is also possible to choose any other angle of rotation size as measuring cycle, for example 270 ° or 500 °. It is important that the measuring cycle determined based on a defined angle of rotation of the winding core becomes.
  • the method according to the invention is a pure measuring method in which the winding parameter is determined becomes.
  • the tape wrap is then provided with information about the measured winding parameters sent to the recipient. Based on the parameter, the receiver knows which maximum Unwinding speed of the tape reel to be unwound may.
  • the invention also enables regulation of the parameter in the Meaning of keeping constant during the winding process. For this a regulation is carried out, whereby as a manipulated variable for keeping constant of the winding parameter the contact pressure of a pressure roller or changed the tensile force of the drive of the winding core becomes.
  • the computing device has a table contains the calculated diameter for each interval of the angle and the absolute value of the winding length there is the possibility of using the accruing Data for other applications. For example, kick when winding a tape tear or a patch, then is it is customary to cut out the relevant areas and the Ultrasonically weld the ends of the strips together on the winder. The last layers are unwound from the winding before welding. The current material run length goes through this unwinding of the wrap lost. According to the invention Welding based on the next measuring cycles the current diameter of the winding can be calculated. This diameter comes with compared to the diameters stored in the table. The Barrel length of the diameter with the current diameter corresponds as a new setting value in the meter counter of the Wicklers written. Here, if the current diameter does not exactly match a stored diameter, an interpolation is done.
  • the drawing shows a winding core 10 by one (not shown) motor is driven.
  • a web of material 11 is wound up on the winding core 10 to form a coil winding 12.
  • the strip material 11 is a thin foil made of aluminum, how they as a vapor-tight layer of beverage bags and the like. used becomes.
  • the material thickness is 6 to 10 ⁇ m.
  • the strip material 11 comes from a constant production line Speed. It runs between two rollers 13, 14 through, the slip-free on opposite sides of the tape material attack and are not driven.
  • the wave of Roller 13 is provided with a pulse generator 15, which is high Angular resolution has numerous pulses per revolution of the shaft supplies.
  • the pulse generator 15 forms a measuring device 16 to determine the incoming winding length.
  • a pulse generator 17 is coupled to the shaft of the winding core 10. This delivers with each revolution of the winding core 10 an impulse, a very short impulse at the zero crossing.
  • the pulse generator 17 forms a measuring device 18 Determination of the revolutions of the winding core 10.
  • the measuring devices 16 and 18 are equipped with an evaluation circuit 19 connected.
  • the output pulses of the counter 20 limit each a measuring cycle, here ten revolutions of the winding core matters.
  • the pulses from the measuring device 16 are fed to a counter 21, whose reset input R is connected to an OR gate 22 is.
  • the counter 21 is provided with a hold circuit 23. This takes over the counter reading of the counter 21, if at their Latch input L a control pulse occurs.
  • the gate entrance L is connected to the output of the counter 20. If the counter 20 generates an output pulse at the end of a measuring cycle, The holding circuit 23 takes over the counter reading of the counter 21. This is simultaneously via the signal at its reset input R reset to zero.
  • the reset input R receives via the OR gate 22, the output signal of the counter 20 or a Control signal from the control cabinet controlling the winding system 24 is coming.
  • the output of the holding circuit 23 is connected via a line 25 connected to a computing device 26.
  • the computing device 26 is a PC with a screen and keyboard that the user can use Values such as material thickness of the strip material 11, final size the winding 12 and the like. can enter.
  • the computing device 26 is connected to the control cabinet 24 controlling the winding installation.
  • a measurement cycle exists in the present embodiment from ten revolutions of the winding core 12. During the measuring cycle are the pulses generated by the pulse generator 15 in the counter 21 counted. At the end of the measuring cycle, the counter reading of the counter 21 transferred to the hold circuit 23 and from this Line 25 supplied to the computing device 26. At the same time the next measuring cycle begins immediately.
  • Both parameters, winding density and strength of the included Air layer can on the screen of the computing device 26th are displayed. These parameters can be used in the following Processing of the tape reel can be recycled. For example After the winding process, each ribbon roll is placed in an annealing furnace annealed. The duration of the annealing process depends essentially on the Determines the amount of trapped air. In dependence of the thickness of the enclosed air layer can affect the duration of the Annealing process can be varied.
  • the traction with which the Winding core 10 is driven can be varied. While the belt speed constant, the tractive force of the motor can be changed. An increase in traction means a decrease in Air pockets.
  • Another way of influencing the trapped Air volume is the pressure of a pressure roller 28 to change by a pressure element 27, here a cylinder, pressed against the winding 12 at the run-up point of the band 11 becomes.
  • An increase in the contact pressure means a decrease of the air volume to be enclosed in the wrap.
