Definitions

  • the present invention is concerned with the application of fiber length measurement in the Blowroom or carding mill of a spinning mill.
  • the conventional blow room lines and in the subsequent carding is often the same textile fibers over longer periods of time, e.g. Cotton, man-made fibers, or mixtures thereof (assortments) processed.
  • the Settings of the textile processing machines are usually based on the corresponding Material types adjusted or optimized only once and then no longer changed. Such operating parameter settings are usually cumbersome and require relatively much time.
  • the production line may require fiber material samples at various points remove and some of these with complex and time-consuming measuring methods analyze in the laboratory (e.g. measurement of the staple fiber shortening, number of nits, Short fiber content).
  • DE-A-196-51-893 describes a method and a device in which the staple fiber length and the number of nits are measured on a card. The measured values determined are used to set the operating parameters of the card. To optimize production, the number of nits and the fiber length distribution are determined and linked. Based on this link, a regulation or control specifies the optimal operating parameters. The measurement is carried out online (measurement of the stack diagram and number of nits). The following two operating parameters (manipulated variables) are adjusted: the distance between the sets of covers and the drum (carding gap) and the speed of the drum. The optimal setting values are regulated or determined on the basis of stored characteristic diagrams / characteristic curves which also contain the associated machine setting data.
  • the input data are compared with these maps / characteristic curves.
  • the fiber samples required for evaluation are suctioned off.
  • extraction can take place at the following locations: on the customer, on the doctor roller, on the squeeze rollers, or on the licker-in.

  • the fiber reduction amount is determined from the difference values of the measurements. Depending on the value, those working elements that influence the carding gap are readjusted or optimized (influencing the carding intensity).
  • Fiber samples are taken at the following locations: on the customer, on the doctor roll, before or after the squeeze rolls, on the reel or on the licker-in.
  • the samples are evaluated automatically and online, ie the stack diagram is determined from the values.
  • the evaluations serve as input data for the regulating and control devices, which determine the optimal machine setting data.
  • the optimal machine setting data with regard to the carding gap are passed on online to those working elements or actuators of the carding machine which control the distance between the clothing of the drum and the cover.
  • the control and regulating devices have stored characteristic curves.

Such devices are known from the prior art and are subject to constant further development. These measuring devices are not discussed in the following because they are also not the subject of the invention.
  • clamping distance is understood to mean the distance between the clamping point of the feed trough feed roller (ie the outermost or narrowest nip between the trough and the feed roller at the trough outlet) and the first licker-in.

  • a conventional belt drive can be used to change the speed of the licker-in (s), but the use of a frequency converter is preferred.
  • the term "transmission factor indicates what percentage of the fiber mass on the reel is transferred to the customer with each revolution of the reel.
  • a transmission factor of 20% means, for example, that 20% of the fibers on the reel change to the customer per revolution. In other words, each fiber runs an average of five times with the drum (and is carded) before it is picked up by the customer.
  • the inventive concept also includes the possibility that the actuator which changes the transmission factor can consist of several means Throughout the patent specification, the term “actuator” is also to be understood as meaning several means.
  • an actuator can include several (mechanical) adjustment mechanisms with the associated motors and possibly the associated frequency converters or electronic controls.

  • the production is equal to the outlet speed x belt weight and the belt weight should not be changed, the production is determined solely by the outlet speed and thus by the circulation speed of the customer.
  • the sliver weight itself is determined by the weight of the wadding and the basic warpage, the ratio of the peripheral speed of the customer to that of the feed roller (ie sliver weight equals wadding weight multiplied by the effective warpage in the card).
  • the speed of the feed roller is thus also indirectly determined by the peripheral speed of the customer.
  • Small variations in the wad weight of the wadding template fed to the card feeding device are attempted to be compensated for with small changes in the feed roller speed (change in the basic warping).
  • Short-term fluctuations in the weight of the cotton wool in front of or in the feed device of a card are recognized by a corresponding measuring device, whereupon the speed of the feed rollers is adjusted accordingly via a control system (including actuators).

  • This system can be used by the operating personnel also on adjustments to the operating parameters or on quality fluctuations draw attention to the processed fiber material.
  • the monitoring system 44 also with other data and information systems to link or integrate this into it.
  • the data and Information system called "SPIDERweb" by the applicant.
  • the inventive idea can be implemented particularly well if the in the figures described processes take place "online". That means the measurements, evaluations and controls take place continuously during operation.
  • the goal is one if possible short reaction time between the occurrence of a change in the fiber flow (or Fiber property) and the appropriate influencing of the work element or elements receive.
  • An important factor here is the performance of the measuring devices: The faster they can measure and evaluate a fiber property, the shorter is the total response time of the system.
