Definitions

  • the present invention relates to a plant and a method for producing a combed fiber sliver according to the preamble of claims 1 and 7.
  • the state of the art in textile technology it is known to feed carded and drawn fiber slivers to a winding machine, which then produces a lap.
  • the lap(s) are the template for producing a combed fiber sliver in a combing machine.
  • 5 to 6 combers are assigned to a winding machine, which produce a lap from 20 to 36 fiber slivers.
  • At least 8 laps are then fed to the combing machine for combing, from which a drawn fiber sliver with as consistent a mass as possible is produced.
  • the beginning of the lap which lies directly against the winding tube, cannot be drawn to the desired mass because this beginning must first be threaded through the various pairs of rollers and therefore cannot be drawn.
  • the lap weight for the first few meters lying on the winding tube is too high.
  • the end of the batting sliver which is on the outside of the lap package and is the first to be inserted into the combing machine, cannot be stretched to the target weight on the combing machine because it also has to be threaded into the combing machine first.
  • the batting weight is too high for the first few meters.
  • the batting package has a sliver weight that deviates from the target value, at least at the beginning and end of the package, and this weight must be corrected, for example, by stretching or adjusting the draft of the eight or more combed slivers in the combing machine.
  • each drafting system of the combing machine has several individually driven drafting rollers in the main draft, which entails high investment costs.
  • the weight fluctuations remain in the sliver because they cannot be corrected.
  • the WO93/06275 Describes a combing machine in which the sliver mass of the lap roll is assigned to the roll length.
  • the combing machine's control system is designed to compare the sliver mass with a target value and assign it to the roll length. Using this data, the draft or tension of the lap roll in the combing head can be adjusted.
  • the invention is based on the object of developing a system and a method for producing a combed fiber sliver such that the fiber sliver produced in the combing machine has a constant fiber mass with little effort.
  • the invention relates to a system for producing a combed fiber sliver, comprising a winding machine with at least one combing machine, wherein the winding machine is designed to produce a group of several lap rolls from lap sliver for each combing machine.
  • the lap rolls can be transported to at least one combing machine and presented to the combing heads.
  • the at least one combing machine is designed to produce a combed fiber sliver from each lap roll, which is subsequently stretched with the other fiber slivers of the combing machine to form a single fiber sliver.
  • the invention includes the technical teaching that the at least one combing machine has a measuring device configured to measure the deviation in the sliver mass of this one fiber sliver.
  • a control system of the combing machine is configured to compare the sliver mass of this fiber sliver with a target sliver weight and to assign it to the unwinding length of the lap roll. Using this data, the draft and/or tension of the lap roll on the winding machine for the next group of lap rolls for this combing machine can be adjusted across the roll length.
  • the advantage of the process is that all combing machines can be equipped with a simpler and cheaper drafting system, where only one pair of drafting systems needs to be provided with a drive in the main drafting and still a constant Sliver weight can be produced.
  • the previous second drive in the main drafting unit can be dispensed with in the drafting system, as the sliver weight optimization takes place largely in the winding machine.
  • the combed sliver is optimized due to the manual or automatic data exchange between at least one combing machine and the winding machine.
  • the operating data of the winding machine are adapted to the deviation of the sliver from the target sliver weight on the combing machine via the winding length.
  • the drafting and/or tensioning on the winding machine can be achieved by controlling at least one drafting system and/or by changing the relative speed between two winding elements.
  • the drafting can advantageously be changed by at least one drafting system and/or by pressure rollers on the winding machine.
  • Optimizing the sliver mass of one fiber sliver on the combing machine can begin with the drafting systems or pressure rollers by optimizing the drafting and doubling of the incoming fiber slivers or drafting slivers into the winding machine.
  • the tension of the batting can be influenced preferably via the winding rollers, which can form a possible type of winding element.
  • the data for changing the draft and/or tension on the winding machine can be transferred manually or by means of a system control system from the at least one combing machine to the winding machine.
  • the combing machine control system can, for example, show on the display which length ranges of the batting sliver require an adjustment of the mass of the batting sliver. The operator can enter this information into the winding machine control system manually or using a data stick or via tablet or smartphone.
  • a system control system can carry out the data exchange automatically and, using the measured data evaluated in the combing machine control system, control the winding machine for the next set of batting rolls with regard to draft and tension over the roll length.
  • the group of lap rolls can be transported manually, semi-automatically, or automatically by means of a transport system to the corresponding combing machine.
  • the winding machine informs the operator on the operating display to which combing machine the group of lap rolls should be transported.
  • semi-automatic transport the operator only has to insert the lap rolls from the transport trolley into the combing machine, as the transport trolley is loaded with the group of lap rolls from the winding machine and transported to the to the associated combing machine.
  • the cotton rolls are removed from the winding machine, transported, and inserted into the associated combing machine automatically.
  • the measuring device is preferably arranged on or in a sliver funnel of the at least one combing machine, wherein the sliver funnel is arranged downstream of a drafting system.
  • the measuring funnel is designed to measure the sliver weight of the fiber sliver at the sliver funnel.
  • the combing machine control system determines the deviations from the target sliver weight F of the combed fiber sliver, which are assigned to the unwinding length of the lap roll.
  • the unwinding length of the lap roll can be determined by back-calculating the fiber mass at the sliver funnel and the drafts at the combing machine, so that the fiber mass deviation can be assigned to the winding length with an accuracy of, for example, several centimeters.
  • the back-calculation takes place in the control system of each combing machine, which either displays the data for the operator or transmits it to the higher-level control system of the system.
  • the determined data is used to adjust the draft on the winding machine so that the end of the lap sliver, which is first presented to each combing head, is drafted in such a way that a constant sliver weight is achieved.
  • the inventive method for producing a combed sliver comprises a winding machine with at least one combing machine, wherein the winding machine produces a group of several lap rolls from lap sliver for each combing machine. This group of lap rolls is transported to the associated combing machine, and a separate lap roll is presented to each combing head. A combed sliver (4 to 16 slivers per combing machine) is produced from each lap roll, which are subsequently drawn into a single sliver.
  • the invention is based on the finding that deviations in the sliver weight from the target value can be compensated for by adjustments on the winding machine, at least for the next group of lap rolls.
  • the invention is characterized in that the deviation in the sliver mass of one sliver is measured, compared with the target sliver weight, and assigned to the unwinding length of the lap rolls. Using this data, the draft and/or tension on the winding machine for the next group of lap rolls (1) is adjusted across the winding length.
  • the process can be optimized through the interaction of two machines in a production line, which makes the downstream combing machine more cost-effective to manufacture, as a drive in the main drafting section of the drafting system is eliminated.
  • the combing machine consumes less power, is more cost-effective, and can be constructed more compactly.
  • a constant sliver weight can be achieved on the combing machine.
  • the draft and/or tension adjustment occurs at the beginning and/or end of the unwinding length of each lap of a group of laps. This allows a constant or varying lap weight to be produced for the group of laps over the lap length, thus optimizing the combing process.
  • the measures described above can be used to produce a constant batt weight over the entire lap length.
  • the system and method can be used to vary the batt weight over the lap length, for example to compensate for a process change on the combing machine.
  • a different winding tension (tension) can be advantageous depending on the diameter of the batt.
  • An adapted batt weight can be beneficial for an optimal combing result.
  • no tension can be applied to the batt lap when the batt sliver is inserted.
  • the usual draft is missing, so that an increased mass of fibers is combed out.
  • it can be useful to reduce the batt weight on the winding machine over the corresponding length range of the batt sliver by, for example, 3% to 6%.
  • Figure 1 shows a system for producing a combed fiber sliver, with at least one winding machine W, an automatic or manual transport system T, and several combing machines K1 - K6.
  • a winding machine W is fed with fiber or draw frame slivers 9 from several cans 10, which then produces a lap roll 1 for presentation to a combing machine K.
  • the lap rolls 1 can be transported manually, semi-automatically, or automatically from the winding machine W to the combing machines K1 - K6 via a transport system T.
  • Manual transport of the lap rolls W can be via a manually movable deposit carriage that can accommodate at least 8 or more lap rolls for presentation to a single combing machine.
  • Semi-automatic transport can be via an automatically movable deposit carriage that, after an initial loading with lap rolls, automatically moves them to the corresponding combing machine and conveys them there into the receiving device.
  • Automatic transport can be achieved via an overhead conveyor system that removes the appropriate number of lap rolls 1 from an intermediate storage device downstream of the winding machine W and automatically transports them to the feed device of the combing machine and deposits them there.
  • a controller S is configured to compare the operating data of the winding machine W with the operating data of the combing machines K1 - K8 and control them accordingly.
  • a lap roll 1 is placed on two winding rollers 2 and 3 (winding calender) of a winding machine W, which can be rotated in the direction of the arrow.
  • a lap band 4 (shown in dash-dotted lines) passes through a calender (pressure calender) consisting of at least three pressure rollers 5, 6 and 7, before it runs to the lap roll 1 and is wound up thereon.
  • the lap band 4 is drawn in a drafting system 8 of the winding machine W from one or more fed fiber webs or from adjacent draw frame belts 9. Another drafting system or several drafting systems can be arranged upstream of the drafting system 8.
  • a table calender consisting of two rollers 11, 12 is arranged between the output rollers of the drafting system 8 and the pressure roller 5 of the pressure calender.
  • a deflection roller 13 is arranged upstream of the input rollers of the drafting system 8, which deflects fiber or draw frame belts 9 from upstream cans (not shown) and a creel (not shown).
  • A indicates the working direction of the belt winding machine.
  • Arrows B and C indicate the running direction of the drawn draw frame belts 9 or batting belts 4.
  • the direction of rotation of the rollers 2, 3, 5, 6, 7, 11 and 12 as well as of the lap 1 is indicated by curved arrows.
  • the drafting system 8 can be designed as a 3-over-3 drafting system, i.e., it consists of three lower rollers and three upper rollers. Alternative drafting system concepts, such as a 4-over-3 drafting system, are possible.
  • the fiber composite is drawn from several fiber or drafting slivers 9.
  • the drawn drafting slivers 9 are drawn in direction B as batting sliver 4 by means of the calender rollers 11, 12 and deflected in direction C.
  • the winding rollers 2, 3 each have a separate drive, at least one of which is controllable or adjustable, so that the winding rollers 2, 3 can be operated at the same or different speeds.
  • the winding rollers 2, 3 are driven at a tension of 0 to -5%. This means that a winding roller 2, 3 - preferably the winding roller 3 - is operated at a speed up to 5% lower than the winding roller 2.
  • the tearing process for the wound lap roll 1 can be modified via the separately controlled or regulated drives of the winding rollers 2, 3.
  • the lap band 4 is torn off between the pressure roller 7 and the winding roller 2, but one end still remains between the winding roller 2 and the pressure roller 7, whereby the band winding machine can continue to run automatically after a new core 1a has been inserted.
  • Manual insertion of the lap band 4 is therefore no longer necessary.
  • Manual insertion of the draw frame bands 9 is only necessary when changing cans.
  • the pressure rollers 5, 6, 7 are each provided with a separate and controllable drive, so that in the event of bubble formation, the distortion between the pressure rollers 5, 6, 7, but also between the pressure roller 7 and the winding roller 2, can be adjusted. The process for producing a lap roll 1 can thus be further optimized and stabilized, allowing for higher production speeds.
  • a combing head 20 is shown, of which at least eight are mounted on a combing machine. For reasons of clarity, the embodiment is shown and described using only one combing head 20, with the details shown being installed on each of these combing heads except for the common drive units and the sliver deposit.

  • the nipper unit 27 can be moved back and forth via levers and is driven via a shaft 31 that is connected to the gear 23. According to the example shown, the nipper unit 27 is in a forward position and transfers the combed-out fiber tuft to a subsequent pair of detaching rollers 32.

  • the circular comb 33 is also drive-connected to the gear 23.

  • a ratchet wheel (not shown) is mounted on the feed cylinder 26. This ratchet wheel is rotated step by step by the reciprocating movement of the nipper unit 27 via a ratchet (also not shown), thereby feeding the batting strip 4 to the jaws of the nipper for combing.
  • the batting strip 4 is continuously unwound over the winding rollers 21, 22 by the rotational movement generated by the batting roll 1 and passes via the clamping point of the pressure roller 30 with the roller 25 into the area between the clamping point and the feed cylinder 26.
