Definitions

  • the invention relates to a method for controlling a treatment plant for textile fibers, in particular cotton fibers, according to the preamble of claim 1.
  • a treatment plant is also referred to as a blow room / carding machine in yarn production.
  • a card sliver is made from disordered cotton fibers, which is then processed into a yarn by stretching, combing and spinning.
  • At the producer level there is talk of a ginning plant or ginning plant in connection with the harvested cotton capsules. There the seeds are separated from the fibers and, if necessary, further impurities are removed.
  • This object is achieved according to the invention with a method which has the features in claim 1. No samples are taken, but the fiber material flow is continuously monitored for at least two different physical measurement parameters. Different material properties can be derived from these measurement parameters either individually or in combination or sub-combination. On the basis of a comparison with previously entered target values, it is possible to intervene in the treatment stations or in the transport system.
  • material properties is also understood to mean different degrees of soiling of the fibers or flakes, impurities being able to occur directly on the surface of the fibers or as a separate admixture. Homogenizing is understood to mean achieving a fiber mixture that is as uniform as possible.
  • a plurality of properties of the material are preferably determined on the sensor system. These can be flake properties (size, density, distribution, color, shape, moisture, temperature) or fiber properties (surface coating with natural wax or artificial substances, fiber fineness, maturity, length, stack distribution) or other properties if necessary.
  • the ripeness of the cotton can be determined from the wavelength range 1500 to 1550 nm and the moisture derive from the wavelength range around 1900 nm. Relationships with regard to surface properties of fibers, in particular dependencies on moisture and chemical composition, are described in “Duckett, KE, Surface Properties of Cotton Fibers", in “Fiber Science Series, Surface Characteristics of Fibers and Textiles, Part I, MJ Schick, Ed. , Marcel Dekker, NY 1975 ".
  • contactless sensors that transmit or receive electromagnetic waves and / or ultrasound waves are particularly suitable.
  • tactile sensors would also be conceivable, for example in the form of sensors that protrude into the fiber material flow and, for. B. measure the flow resistance, the electrical conductivity, the momentum of the flakes or particles, etc.
  • the near infrared range is particularly well suited to recognizing a large number of substances or properties in the reflected or transmitted spectrum. With at least two characteristic frequencies, a "fingerprint" can be defined, from which different material properties can be derived.
  • Fiber dimensions in particular fiber fineness, can be determined particularly advantageously with laser sensors.
  • a diffraction pattern and / or control pattern is formed for this purpose.
  • the measured variables can be determined with at least two sensors at different points in the treatment system, based on the transport direction.
  • an electromagnetic sensor for metal parts and an optical sensor for moisture or wax coating are conceivable.
  • a sensor it is also possible for a sensor to work on several frequencies or measuring principles and for two or more measurement signals to be determined in this way at the same point in the fiber material flow.
  • the measured variables are averaged or evaluated in different time periods.
  • the actual values determined require different reaction times. For example, a detected contamination must be eliminated by a pressure surge or a deflection flap within milliseconds after detection.
  • the bale cutter can be influenced in a matter of seconds, while the duration of the control intervention with changing moisture content e.g. Can be 5 to 10 minutes or the mean value is formed from measurements in larger time segments.
  • the treatment stations are preferably connected to a pneumatic transport system. There it may be necessary to remove the conveying air before a treatment station and to supply it again after the treatment station. But other conveyor systems such as conveyor belts or screw conveyors would also be conceivable.
  • bale removal machine it is also conceivable to control the bale removal machine to change the removal movement when foreign substances and / or deviating material properties are detected. For example, a specific bale can be identified that delivers an above-average proportion of soiled or otherwise deviating fibers. The removal movement can be controlled in such a way that the removal depth and / or speed is changed on each bale until manual rejection is possible.
  • the method according to the invention also permits data logging of the process and classification of the intermediate products and thus optimization of the quality control.
  • Influencing the transport system is also to be understood in particular as the skipping of a treatment device in a bypass line.
  • the flow of fiber material could be fed to different treatment stations on a conveyor switch depending on the fiber properties.
  • the invention also relates to a device for controlling a treatment plant for textile fibers, in particular cotton fibers, which is characterized by the features in claim 16.
  • a blowroom line / carding machine 1 consists of a bale removal machine 3, a pre-cleaner 19, a separator 4, a mixer 5, a fine cleaner 6, possibly a second fine cleaner 6 'and a carding machine 7.
  • the individual treatment stations are over a pneumatic transport system 2 connected to each other.
  • fiber flakes are removed in layers from the individual bales 11 and fed to the foreign matter separator 4 in a pre-cleaned form in already dissolved form.
  • This has a sensor system, for example in the form of CCD cameras 12, with the aid of which color changes can be determined. Colored foreign substances are excreted.
  • NIR sensors 13 can also be provided, which for example determine the degree of moisture, the wax coating or other parameters.
  • the fibers are then fed to a mixer 5 which is equipped with various filling chutes 14.
  • the material columns in the individual shafts are compacted by their own weight and then again removed in layers.
  • the various fiber batches are mixed.
  • other types of mixers are also known.
  • the sensor system is advantageously installed in front of the mixer 5, so that the mixing process can be intervened or an intervention in the bale removal can be carried out as quickly as possible.
  • the sensor system should also be arranged at a location where the fibers or flakes are suitable to get presented. This can also be, for example, on the boom of the bale removal machine 3, in the area of an opening member or directly in a suitable area of the fiber transport line.
  • a cleaning line / carding machine is again shown schematically in the diagram according to FIG.
  • the cotton bales are removed from a warehouse and prepared at 16 for bale removal, i.e. freed from the outer wrapping and identified with respect to the specified warehouse data.
  • the bales are placed in order to be removed by means of the bale removal machine 3.
  • the flakes are opened at 18 in order to be presented to the sensor system 10 in the most suitable form.
  • the flakes or fibers then reach the separator 4, where foreign substances are removed.
  • the flakes are pre-cleaned, where mainly vegetable waste is excreted.
  • the flakes are dosed so that they can be fed to the mixer 5 or preferably several mixers in a classified and dosed form. After mixing, the fine cleaning takes place in cleaner 6.
  • cleaner 6 There is an excretion of fine plant parts and other foreign matter such as sand, etc. Only now do the cleaned flakes reach card 7 where the card sliver 15 is filled into a can 21 for further processing.
  • the pre-cleaner 19 could also be arranged between the bale removal machine 3 and the separator 4. The number and arrangement of fine cleaners in the line can also vary.
  • the sensor system 10 could of course also be arranged at a different location, or different sensors that work according to different physical principles could be arranged at different locations on the fiber transport line.
  • the sensor system transmits different physical measurement variables 22 to an evaluation device 8. Actual values 23 for different fiber properties can be called up there.
  • a control device 9 the actual values are compared with entered target values 24. The deviations determined in this way form control signals 25 for influencing various machine parameters.
  • the separator 4 is actuated and / or the mixing process, the cleaning process or the carding process is influenced. Orders can be placed on the bale feed 17 or on the bale preparation 16 in order to remove or replace certain bales.
  • bales are identified by identification signals 26, which enables fiber properties to be traced back to the corresponding bales.
  • the illustration according to FIG. 3 is intended to clarify that different measurement variables 22 on the sensor system 10 are used for this can be used to identify various material properties 27 using correlation methods to be determined beforehand.
  • the three different matrices M1, M2 and M3 show that signals averaged over different time periods can also be taken into account for the signal formation.
  • a near infrared sensor can have the frequency ranges A, B, C, with each range correlating with specific material properties a, b, c, d or e. This can be the moisture content, the degree of maturity, foreign substances, the wax coating or another size.
  • the signals determined for very short-term control interventions in the millisecond range for the excretion of foreign substances can be evaluated on the matrix M1.
  • the fiber properties c, e, f and g e.g. the stickiness, derived, but which are used for medium-term tax interventions in the range of seconds.
  • the bale removal machine could skip a certain bale if a certain fiber quality and / or a strong contamination is found there, or limit the removal of this component in the sense of a controlled admixture.
  • the measured variables D, E and F are used to determine the fiber properties a, b, c, d and g e.g. Moisture closed. Rule interventions lasting longer are triggered here, e.g. to change the machine parameters of a cleaner or a card or to change the indoor climate.
  • the sensor system can be expanded as required to optimize the processing process.
  • it does not necessarily have to be a processing plant for cotton fibers.
  • Processing processes for Animal fibers or, in certain cases, synthetic fibers can be controlled in the same way.
  • FIG. 4 schematically shows a ginning installation 42, which can also be controlled using the method according to the invention.
  • the fiber properties are not determined periodically as in the prior art, but continuously on the material flow.
  • the raw cotton is unloaded from harvest vehicles 44 into a buffer store 45 and layered there. Here the flakes are homogenized for the first time.
  • the cotton pneumatically reaches a feed module 28 and is then subjected to a first cleaning process in a sand separator 29.
  • the cotton then passes through a first tower dryer 30 and, after passing through a first diagonal roller cleaner, through a separating machine 31 for larger plant parts.
  • the excess moisture of the fibers is extracted in a second tower dryer 32.
  • a second cross roll cleaner 39 and a blow cleaner 34 remove further foreign matter before the cotton fibers are fed to a cleaner (extractor) 35.
  • a gin 36 There, primarily plant-based foreign substances such as Grains, fruit capsules etc. removed.
  • the fibers finally reach a fiber fine cleaner 37 (lint cleaner), where the high-quality fiber parts of the cotton plant are further cleaned.
  • the pneumatic onward transport finally leads to a baler 38.
  • a first sensor 40 is arranged in front of the first tower dryer 30 or possibly already after the buffer store 45 for influencing machine or conveying parameters.
  • a second sensor 41 is in the transition area between the cleaner (extractor) 35 and the gin 36. The two sensors 40 and 41 and, if appropriate, further sensors can be used to control the tower dryer, the ginning machine and the fiber fine cleaner and to remove foreign substances, so that fiber bales 43 of known, as constant as possible quality can be produced.
