Definitions

  • the invention relates to a machine for forming cotton rolls incoming cotton, with a holder for a winding tube, with at least one movable drive element for moving the circumference of the saddle wrap and with a loading device for pressing the cotton roll against one another Drive elements with a diameter that can be controlled by a control device force dependent on the wadding.
  • the control device contains which controls, for example, a pressure reducing valve of the loading device mechanical element, which with increasing diameter of the cotton roll is moved mechanically. If the arrangement is such that the winding tube with the growing diameter of the wadding can shift mechanical Element are moved with the holder of the winding tube. The item can be used for Actuation of the pressure reducing valve have a curve.
  • Such mechanical Systems are relatively inflexible.
  • Other known machines include for the control of the loading device an electronic control device, to which a signal is supplied which corresponds to the Represents diameter of the wadding.
  • A can be used to generate this signal mechanical guide element can be used or if the winding tube does not move during operation, a proximity sensor, e.g. Ultrasonic sensor.
  • the object of the invention is to build a machine of the beginning to simplify the specified type.
  • the machine according to the invention is thereby characterized in that the control device is fed a signal which the is the cumulative length of the cotton tapering to the cotton roll, and that the Control device contains computer means for calculating the diameter of the Cotton wrap from this signal and from other signals, which the weight of the Cotton wool in units of weight per unit length, the specific weight of the cotton wool Represent the width of the cotton roll and the diameter of the winding tube.
  • the signal representing the cumulative length of the cotton tapering to the cotton roll is always available anyway in machines for forming wadding because it is it is desired to wind a predetermined wad length on the wrap.
  • a winding tube 1 is through a holder in the form of two fixed to the frame, axially insertable into the winding tube 1 pin 2 rotatably.
  • an incoming cotton wool 4 which is formed by pairs of calender rollers 5, 6, 7 comes, wound up to form a wad of cotton 8.
  • an endless drive belt 9 is placed around Deflection rollers 10, 11, 12, 13, 14 is guided. The drive belt 9 is turned one or more of these roles, for example role 10 and / or role 11, emotional.
  • the drive belt 9 is pressed against the circumference of the cotton roll 8 by a tensile force is generated in the drive belt.
  • This traction is from one Pneumatic cylinder 15 generates, the piston rod with that in the machine frame horizontally displaceably arranged deflection roller 14 is connected.
  • the experience teaches that the pressing force of the belt 9 against the circumference of the cotton roll 8 or the tensile force in the belt 9 can be changed in the course of the construction of the satin wrap so that a mutual matting of the wadding layers on the wrap and a Lifting the cotton wool off the wrap at high speed can be avoided.
  • the wad of cotton is hard, but without interlocking the Fibers from adjacent layers of wadding, as such curdling later when unwinding the Cotton wool from the wrap could result in protruding fibers.
  • the Pressing force of the belt 9 to the circumference of the cotton roll 8 with increasing The diameter of the cotton wrap will become smaller, because otherwise excessive flexing will occur the size of the cotton wrap could occur.
  • FIG. 2 shows a function according to which the magnitude of the tensile force F in the drive belt 9 depending on the diameter d of the cotton roll in a special Application example should decrease.
  • a function can be in an electronic Control device 16 (Fig. 1) can be entered. It is easily possible that the function in the control unit 16 can be set for different applications.
  • the control device 16 controls a pump 17 and a pressure control valve 18, which feed the pneumatic cylinder 15.
  • the control unit 16 should of course always in the course of the construction of the satin wrap 8 the current diameter of the cotton roll to be known.
  • All machines for forming cotton rolls contain a sensor (encoder) which continuously detects the cumulative length of the cotton coming into the cotton roll so that the winding process can be interrupted as soon as a predetermined length of cotton is wound on the cotton roll.
  • a rotary encoder 19 is shown as a sensor, which is coupled to one of the calender rolls of the last pair of calender rolls 7. The rotary encoder emits a signal which represents the cumulative length 1 of the cotton 4 running towards the cotton roll 8. This signal is fed to the control device 16 via a line 20.
  • control device 16 is supplied with further signals via lines 21, which indicate the weight G of the cotton 4 supplied in weight units per unit length, the specific weight y of the cotton, the width b of the cotton web 4 or cotton roll being fed and the outer diameter d o represent the winding tube 1.
  • These further signals or the values of G, y, b and d o can be manually entered into the controller 16, since the values are usually known a priori and can be determined in advance. It is therefore generally not necessary to continuously measure one or more of these values by means of one sensor each and to supply the measurement signals to the control device 16.
  • FIG. 3 schematically shows parts of another machine for forming Cotton wrap.
  • a winding tube 31 is in shape by a bracket held rotatably by two pins 32 which can be inserted axially into the winding tube.
  • the cones 32 are attached to support arms 33, the lower ends of which are attached to pivot levers 34 are articulated, which are pivotally mounted about an axis 35 fixed to the frame.
  • the cotton wrap 41 (or initially the winding tube 31) is rotatable on two axes fixed to the frame mounted, drivable winding rollers 42 and 43.
  • a control device 45 corresponding to the control device 16 in 1, controls a pump 46 and a control valve 47, which controls the pneumatic cylinder 44 Food.
  • a rotary encoder 48 which is coupled to the calender roller 40, for example, emits a signal which is the accumulated length of the tapered lap 41 Cotton 40 represents. This signal is transmitted via a line 49 to the control device 45 fed.
  • the control device 45 receives further signals via lines 50 supplied, as described with reference to FIG. 1.
