Definitions

  • the invention relates to a method and an apparatus for Detection and removal of foreign substances in fiber material, in particular in raw cotton, according to the preamble of the claims 1 and 11.
  • the term "foreign substances” in particular Fabrics, cords, foils and fibers that are not in the yarn specified fiber material (e.g. polypropylene fibers understood in the material for the production of cotton fibers).
  • such substances are also to be understood as which is ordinary in connection with vegetable fibers belong to the plant, but which in the subsequent processing the fibers are undesirable, e.g. Trash parts, nits, Seeds etc.
  • WO 96/35831 a comparable type is used Device proposed several sensor arrangements in succession use that react to different parameters, in addition to the line scan camera, for example a sensor that works in the near infrared range. In order to should be achieved that on the subsequent separation device substances can also be excreted which are due to their nature or due to their location in the fiber stream a detection signal only for one of the two detection parameters trigger.
  • DE-A 195 16 569 is also a genre comparable Device has become known in which not only two sensor arrangements reacting to different detection parameters are provided, but also two different separation devices. This is followed by a detector plate for detection of metal parts an optical sensor system for the detection of Foreign fibers, plastic parts etc. While the detector plate a downstream flap is activated Foreign substances that are recognized by the optical sensor system blown out of the transport channel by a pressure pulse.
  • the known methods and devices have the disadvantage that that they are not yet optimal on the entire processing process are coordinated and that the different processing stages for example in the blow room of a spinning mill only insufficiently considered.
  • the material at this point the treatment line due to the low degree of dissolution not be presented to a sensor arrangement in such a way that also fine foreign substances can be excreted in a targeted manner.
  • the elimination process takes place however, too late, are also initially compact Foreign matter is further dissolved or frayed, which is what follows Detection and elimination difficult.
  • the method according to the invention and the associated device are particularly suitable for the treatment of raw cotton in a spinning mill, especially in the blow room and Card room.
  • the related work processes and work machines are described, for example, in W. Klein, "Die Kurzstapelspinnerei” Volume 2, editor: The Textile Institute. Of course, use in connection with the processing of other vegetable, synthetic or animal fibers easily conceivable.
  • the degree of opening of the fiber material between the at least two sensor fields by at least one opening element for the fiber material is increased.
  • the successive sensor arrangements can differ, for example, on foreign substances Size, shape or consistency react. With an even smaller one
  • the degree of opening thus becomes very large, for example Foreign substances excreted, which are generated less frequently as a percentage. Subsequently, with increasing degree of opening, fine foreign substances become eliminated, the improved presentation on the sensor field also a more targeted elimination and thus a reduction the fibers ejected together with the foreign material allows.
  • the successive sensor arrangements can easily different recognition parameters for the same genus react from foreign substances. For example, it would be conceivable Plastic material with different optical sensors in different Detect wavelength ranges.
  • the detection and elimination before or after at least one treatment machine for the fiber material can be a coarse cleaner, for example Trade fine cleaners or a fiber mixer.
  • the Treatment machine is itself with one or more Opening organs provide or act as an opening organ itself. It is also conceivable, at least a first elimination and at least a second excretion directly on the same treatment machine to perform for the fiber material. In order to a multifunctional and compact treatment machine is provided, which reduces the overall machine effort can be.
  • Elimination at the at least two different elimination devices can by means of a pressure pulse or by suction respectively.
  • a deflection by deflection flaps is also conceivable or a combination of different excretions.
  • a particularly advantageous use of multi-stage detection is also possible if the treatment machine is a fine cleaner with at least one cleaning roller and if one first separation device in front of the cleaning roller and one second separation device arranged after the cleaning roller is.
  • each and a separating device form a separating module and that in a fiber treatment line at least two separation modules are arranged at different process stages.
  • Such modules could of course also become one compact detection and separation battery coupled together become.
  • FIG. 1 shows a treatment line 8 in a cleaning row / carding machine.
  • metal separator 11 metal parts are first recognized and excreted before the fiber material a coarse cleaner 12 is fed.
  • This can be, for example, a mono-roller cleaner act as he follows with reference to Figures 5 and 6 is described in more detail.
  • the line is divided into two or more parallel lines each similar treatment machines divided.
  • the fiber material first passes a first spark eliminator 13a, which detects embers caused by sparking and is eliminated.
  • the fiber material is one Mixer 14 supplied in a manner known per se Fiber material from different batches can be mixed can. Fine cleaning takes place in another treatment zone on a fine cleaner 15 before the material a second Spark separator 13b happens. Only now the fiber material arrives in the card 16, also here in front of the card, in the Card or after the card a detection of foreign material is conceivable.
  • Figure 3 shows schematically how fiber material 1 over a certain Conveyor line 2 is transported and how doing so three different stages 6, 6 ', 6' 'by means of a sensor arrangement 4, 4 'and 4 "or by means of a separating device 5, 5 ', 5 "foreign material 7, 7', 7" is excreted.
  • the conveyor section 2 can be practically the whole Cleaning line according to Figure 1 or just over a whole extend certain section of it. Depending on the Degree of opening in the sense of Figure 2 in the first stage in the ratio differ greatly from the last stage. at corresponding programming of the sensor arrangements 4, 4 ', 4 " can also target foreign substances of different sizes are eliminated, z. B. the foreign matter 7 on the first Level are much larger than the foreign matter 7 " the last stage.
  • the sensors and separation devices of the individual stages are via a central control unit 17 or via a corresponding Controlled computer.
  • a central control unit 17 On an input console 32 different parameters could be programmed and it it would also be conceivable to switch off individual treatment stages.
  • the Control unit 17 is connected to the sensor arrangements via control lines 31 or connected to the separation devices. Conceivable would of course also be a remote control, for example via a radio remote control.
  • Figure 4 shows, for example, the use of a multi-stage elimination using the example of a fine cleaner 15.
  • the fiber material first reaches a dissolving unit via the fiber transport line 28 18, if necessary with a buffer shaft connected upstream.
  • the dissolved fiber flakes are then one Feeding shaft 20 fed and in a first sensor field 3 presents the mutually arranged sensor arrangements 4.
  • Detected foreign substances are detected on the first separation device 5 with the help of a pressure surge into the foreign matter container 26 blown out.
  • the fiber material passes between a screen roll 21 and a blind roll 22, being over the screen roll 21 Dust-laden conveying air through the exhaust air line 19 is dissipated.
  • the fiber material is fed over the feed rollers 23 fed to the cleaning roller 24 without pressure. This is with nasal discs or provided with a saw tooth set and tears it Fiber material over a grate 25 arranged on the peripheral region. Fine dirt particles such as e.g. B. sand or also parts of plants, seeds and the like are excreted.
  • a feed line 27 then becomes tangential again Conveying air is fed to the fiber material again in a fiber transport line 28 feed.
  • the coarse cleaner or mono-roller cleaner shown in Figures 5 and 6 12 has a cleaning roller with pins 29, which with a adjustable grate 30 interacts.
  • the fiber material passes through this roller with the help of an axial flow of conveying air on a helical conveyor line, with corresponding Baffles on the housing surrounding the cleaning roller support this course of funding.
  • the fiber material is brushed past the grate 30 thrown up and swirled a lot.
  • sensor arrangements 4 to 4n for example a total of 10 sensor arrangements provided that with appropriate separation devices 5 to 5n cooperate.
  • These separation devices can be tangential be arranged to the cleaning roller, for example briefly before the fiber material is drawn over the grate 30 again. This is also a blowout via a pressure surge possible in a foreign matter container 26.
  • the individual sensors 4 to 4n also by a single sensor 4x, e.g. through a line scan camera are replaced, the signals of which, however, can be precisely identified in terms of position are so that the corresponding separation device can be controlled is.
  • FIG. 7 shows a further embodiment with a stepwise Material excretion, with a separate and an in a treatment machine integrated sensor and excretion module is used.
  • a mixer 14 for example of the Rieter "Unimix” type is a separate separation module 33, for example of the Jossi type "The Vision Shield”.
  • the fiber material then goes into a fine cleaner 15, which can be constructed the same or similar to that in the exemplary embodiment according to FIG. 4.
  • the sensor arrangement 4 ' and the separating device 5 ' are here directly in the Integrated cleaner.
  • the mixer 14 is known per se Provided with vertical filling shafts 34.
  • a conveyor belt 35 on the bottom of the mixer transports the various Batches of fibers from the filling shafts to form a needle slat 36, which continuously strips off fibers and conveys them to the mixing chamber 37.
  • Scraper rollers 38 ensure that only one metered Fiber amount of the cleaning unit 39 is supplied. This works similar to the previously described fine cleaner 15. Also here theoretically a foreign substance detection and Elimination takes place and directly integrated into the Mixer.
  • the excretion module 33 could be programmed in this way, for example be that only relatively large-sized foreign substances are excreted here become. The fine foreign substances are eliminated then with a further increased degree of opening of the Flakes on the fine cleaner 15.
