Definitions

  • the method relates to a method for winding a winding material.
  • the invention further relates to a winding machine.
  • a winding tension is regularly applied to the winding material.
  • the winding tension corresponds to the force (per cross-sectional area) with which the winding material is wound onto the winding body.
  • the winding tension can be adjusted. In other words, the winding tension is the tensile stress of the winding material.
  • EP 2 485 227 A1 discloses a method for winding a winding material according to the preamble of claim 1 and a winding machine according to the preamble of claim 7.
  • EP 2 306 473 A1 describes a wire winding machine and a control system for such a wire winding machine.
  • WO2006133662A1 shows a method and a device for controlling the wire tension of a coil winding wire, in which a predetermined deceleration force is transmitted to the coil winding wire and the respective wire tension of the coil winding wire is detected during the winding process.
  • JPS60105210A shows a belt drive
  • EP926090A2 shows a winding machine in which a controller controls a feed speed depending on a winding speed.
  • EP2617670A2 shows a tension device that can absorb changes in speed and keep a tension constant even when the speed of a wire rod changes.
  • the winding tension especially a non-constant winding tension, is difficult to adjust.
  • the winding tension is preferably set to a constant value.
  • the object is achieved by a method according to claim 1.
  • the object is further achieved by a winding machine with a control device according to claim 7.
  • the invention is based on the knowledge that a free length of the winding material between the support points of the winding material on the winding material and a deflection roller from which the winding material is wound, changes continuously.
  • the change is particularly significant for a winding body with a non-circular cross-section.
  • the invention is based on the knowledge that a winding material should be wound onto the winding body with a predetermined winding tension, which is not necessarily constant over time. However, in many applications, such as winding a battery cell, the winding tension should be kept as constant as possible during the entire winding process.
  • a supply roll is understood here to be a device for storing the winding material.
  • the winding material can also be stacked.
  • the supply roll can be assigned a second rotation speed so that the supply roll provides the winding material at a speed proportional to the second rotation speed.
  • the invention is particularly well suited for winding a winding body that has a non-circular cross-section and/or a non-constant diameter/radius.
  • a winding body is elliptical or rectangular in shape.
  • the process presented here is particularly advantageous for producing battery cells or film capacitors.
  • the winding tension is the tension of the winding material.
  • One way of defining the winding tension is the force that acts on the winding material perpendicular to its cross-sectional area, divided by the cross-sectional area. The cross-sectional area is often constant. The winding tension then corresponds to the force with which the winding material is "pulled away from the rotating winding body during winding".
  • the intended winding tension is the winding tension with which the winding material is to be wound onto the winding body.
  • the intended winding tension can be shown as a function of the orientation of the winding body. For example, this is necessary when winding a wire around a square winding body in order to achieve a good result.

  • the calculation and provision of the settings is done online to the control device.
  • a second support point for the winding material is located on the last deflection roller for the winding material in front of the winding body.
  • the deflection roller is the one from which the winding material is guided to the winding body.
  • a winding tension is also referred to as web tension or winding material tension.
  • the invention is based in particular on the finding that during the winding process on a winding body with a non-circular cross-section, the distance between the support point of the winding material on the winding body and the support point of the winding material on a deflection roller changes as the winding body rotates.
  • a first solution is to compensate for the free length using a dancer roll, whereby the dancer roll assumes a position such that the winding tension is compensated. Such passive compensation is often slow.

  • Such a calculation during the winding process is also referred to as an online calculation.
  • a computing unit is used to calculate the respective setting, whereby the computing unit is assigned to a control device.
  • the control device is used to control or regulate the motors and/or the respective actuators.
  • a winding material brake with adjustable braking power is also advantageous.
  • the winding material is guided over a deflection roller, whereby the deflection roller is coupled to a servo motor and the winding tension can be adjusted by adjusting the rotation speed.

  • a winding material accumulator can be combined with a dancer roll to compensate for slight fluctuations in the winding tension.
  • a variable winding material storage preferably has a plurality of deflection rollers, wherein the distance between the respective deflection rollers can be changed by means of a respective actuator.

  • PI control proportional-integral control
  • PID control proportional-integral-derivative control
  • the intended winding tension is constant.
  • the intended winding voltage is preferably kept constant during battery cell production and the winding of capacitors.

  • the winding tension is kept constant by keeping the distance between the first and third support points constant.
  • the distance between the first and second support point is called the free length.
  • the distance between the first and second support point is not constant, as it changes with the orientation of the winding body.
