Definitions

  • the present invention relates to a tape cutting machine with a motor-driven rotary table for receiving a supply of a tubular textile material to be cut, with a first scanning device which serves to scan the rotational position of a section of the textile material which has been drawn from the supply and has not yet been opened up relative to the rotary table, with a plurality of motor-driven ones rotating conveyor cylinders, each having a number of axially oscillating jacket sections with adjustable stroke, with at least a second scanning device, which is used to scan the position of an edge section of the tubular textile material spanned by the conveyor cylinders, and with a cutting device with rotating cutting tools, by means of which the Textile fabric is cut into at least one band.
  • the invention seeks to remedy this.
  • the invention as characterized in the claims, solves the problem of creating a tape cutting machine which takes into account the above-mentioned peculiarities of the material to be processed even better than before and produce tapes with increased uniformity of their edges and more precise compliance with the bandwidth of an entire tape leaves.
  • the tape cutting machine has a turntable 1. On this turntable, the tubular test cloth to be cut is in a stock state, e.g. stored in a rolled or folded position. This turntable is driven by the motor 11.
  • a bracket 8 is mounted in a carrier 16 which is firmly connected to the turntable 1. This bracket can be rotated to a limited extent in a plane perpendicular to the plane of the drawing sheet.
  • a sensor 9 is present on or in the carrier 16. This sensor is used to scan the rotational position of the bracket 8 relative to the rotary table 1. In particular, the sensor 9 should respond when the rotary position of the bracket 8 relative to the rotary table 1 exceeds a certain value, that is to say the angle.
  • Such sensors are generally available in a wide variety of designs. There may be an electromechanical, purely electrical or optically working sensor.
  • the measured value determined by the sensor 9 of the scanning device 2 is fed to a control device 10.
  • the feed cylinders 3 are driven by the drive motor 12 via a belt drive 17.
  • the control device 10 is connected via the control line 18 to the motor 11 of the rotary table 1 and via the control line 19 to the motor 12 of the feed cylinder 3.
  • the turntable 1 rotates in operation in the same direction as the feed cylinders 3.
  • the conveying cylinders 3 should actually rotate synchronously with the turntable 1, in particular with respect to their peripheral speed, a condition which, however, is not always achievable due to the slippage between the textile material and the conveying cylinders resulting from the reasons mentioned earlier.
  • the textile material lying on the turntable 1 is threaded through the bracket 8 and then stretched around the feed cylinder 3. If the speed of the turntable 1 does not match the speed of the material stretched around the feed cylinder 3, this begins to twist, so that the bracket 8 leads or runs relative to the turntable 1.
  • the resulting change in angle is determined by the sensor 9 and the corresponding control signals are fed via the scanning device 2 to the controller 10, which regulates the ratio of the peripheral speed of the delivery cylinder 3 / speed of the rotary table 1 in such a way that the torsion is eliminated.
  • the speed of the motor 12 of the feed cylinders is changed.
  • the tape cutting machine is further equipped with at least one scanner 6 which scans the position of the upper edge of the textile material to be cut.
  • the scanning element itself a wide variety of designs that are generally available commercially are conceivable.
  • This adjusting device 15 controls the stroke of the jacket sections 4, 5.
  • the control of the movement of the jacket sections 4, 5 is the same as that of the publication already mentioned.
  • the stroke can also be controlled in accordance with the aforementioned embodiment, with the adjustment device 15 obviously being made from one Stepper motor or other drives available on the market.
  • the strokes of all jacket sections 4, 5 of all delivery cylinders 3 can be adjusted or, alternatively, only selected delivery cylinders 3.
  • jacket sections 4 , 5 to adjust only some of the feed cylinders 3.
  • a scanning device 6 can be provided between each of the two delivery cylinders, which, viewed in the direction of travel of the material, can act on the subsequent and / or preceding delivery cylinder.
  • FIG. 2 An embodiment of the cutting device 7 is shown in FIG. 2, which enables a particularly simple adjustment for selecting different bandwidths.
  • the cutting device 7 has two knife shafts 20, 21 driven in opposite directions, the drive of which takes place in a known manner.
  • Each of these knives 13, 13 ', 13 ⁇ is provided with a locking device 22, by means of which the respective knife can be rotatably connected to the same in the desired axial position along the cutter shaft 20.
  • a simple hub with a clamping screw is drawn here as an example.
  • the counter knives 14, 14 ', 14' which complement each other in pairs to the above-mentioned knives of the knife shaft 20 are now supported.
  • the counter knives 14, 14 ', 14' on the knife shaft 21 are only non-rotatable , but freely axially displaceable.
  • a tongue and groove arrangement can be present.
