Definitions

  • the invention relates to a method and an apparatus for Elimination of foreign substances from fiber material, in particular made of cotton, according to the preamble of claims 1 and 9. To prevent as early as possible that this covers the entire subsequent processing process of the Pass through fiber material and only with increasing refinement recognized with a disproportionately high effort and can be eliminated. By excretion on one low processing level will also add value of the intermediate product reached.
  • the presentation of the fiber material flow as broader open Material flow from an existing transport area if possible has the advantage that no special measures such as compression, distribution or the like are. It should also be considered that in the ginning process treated much larger amounts of fiber per unit time than in the blow room.
  • the transport area can therefore easily have a width of several meters.
  • the exposure of the material at least in incident light enables uncomplicated lighting of the open material flow. In addition, however, other lighting means be provided, which lead to a different sensor application lead, especially transmitted light.
  • the means of transport can be, for example Act conveyor belt.
  • Slide on which the fiber material is subjected to gravity is guided past the optical sensor. This does not apply special drive and control means and if appropriate Choosing the slope of the slide can still have high throughput rates be achieved.
  • the contaminated subset of is particularly advantageous Aspirated from the top of the fiber material flow.
  • the suction device The advantage over the transport area is that it can be retrofitted can be easily installed on existing systems. Of course, removal from above would also be included other means, e.g. with mechanical grippers or the like conceivable.
  • the contaminated subset could also be caused by a Compressed air pulse is blown out of the fiber material flow.
  • a Blow out from below would also be easy on one Slide possible, the impurities e.g. in a fluted directly over the slide become.
  • the contaminated subset could also by mechanical deflecting means from the fiber material flow be eliminated. For example, at the end of the Slide flaps arranged by temporary Deflection redirect the contaminants into a waste line.
  • the flow of fiber material in its width of preferably several optical sensors is applied and if the separation device is selective is actuated at the point of the fiber material flow at which based on its width, a foreign substance was detected.
  • the inevitable co-excretion of pure fiber material can be reduced to a minimum.
  • a suitable sensor e.g. with a line scan camera but it is easily possible with a single sensor to control several separation devices. In any case the number of sensors does not have to match the number of separators to match.
  • the elimination of foreign substances is during processing the raw cotton is particularly advantageous between drying the raw cotton and pressing the cleaned cotton fibers to bales, especially before the fine cleaning of the Cotton fibers (lint cleaning) are used.
  • the Fine cleaning Before drying raw cotton is only a foreign matter excretion hardly possible.
  • foreign substances after the Fine cleaning is already divided into smaller individual parts be, which also makes elimination difficult.
  • a module in form a common housing In the device, it is particularly useful if at least the sensor and the lighting device a module in form a common housing.
  • This module can be used without further integrated into an existing ginning system if at the same time a suitable transport area already exists or in a simple way as well can be arranged later. The module is also better protected against the high dust pollution in a ginning facility.
  • the device according to the invention is in a ginning installation particularly advantageous between a dryer and a baler, especially in front of a cotton fiber fine cleaner (Lint-cleaner) arranged.
  • a cotton fiber fine cleaner Lint-cleaner
  • When arranging the Device using a slide is there optimal if the slide is a higher processing machine with a lower processing machine, especially with a heavy material separator (extractor) a ginning machine (gin).
  • extract heavy material separator
  • gin ginning machine
  • These two Processing machines are in known ginning systems already on different vertical and horizontal levels arranged and can be easily with an inclined slide connect with each other.
  • the ginning system 20 according to FIG. 1 is highly schematic and shows different types of treatment machines, which of the raw cotton in the representation from left to right be run through.
  • a sensor unit 15 according to the invention is, for example over a slide between the heavy material separator 29 and the ginning machine 30 as shown below is described in more detail.
  • the outlet of the heavy material separator 29 with the inlet of the ginning machine 30 is connected via a slide 3.
  • a suction nozzle 5 is arranged, which leads to a collecting container 12 leads.
  • the collecting container is equipped with a suction fan 10 permanently acted upon by a suction air flow, the In normal operation, the intake port is shut off with a flap 14 is.
  • the suction side of the fan has a screen wall 13 covered.
  • injector be where only with the help of a compressed air blast a suction pulse is generated.
  • the sensor unit 15 is operatively connected to a Control device 11, which in the case of a sensor signal Flap 14 temporarily opens, leaving a contaminated one Subset of cotton fibers is vacuumed from the slide 3.
  • FIG. 3 shows the construction of a sensor unit 15 as a module presented a little more precisely.
  • an optical Sensor such as a color line camera arranged that their lens light through a deflecting mirror 7 receives.
  • the lighting of the cotton fibers 1 on the slide 3 is carried out via an illumination device 6 consisting of several luminous elements, which on both sides of the optical axis are arranged.
  • the housing 8 In the area of lighting fixtures and the optical axis is the housing 8 with a Glass pane 9 closed.
  • a foreign substance 2 in the cotton fibers 1 is from the line scan camera 4 determined as a color change and causes a control signal for actuating the suction device. The foreign matter is then suctioned off at the end of the slide 3 with the suction nozzle.
  • FIG. 5 finally shows an alternative exemplary embodiment, in which the sensor unit 15 above a conveyor belt 16 is arranged.
  • the cotton fibers fall at the end of the conveyor belt in a shaft 19, one on the side wall Blowing nozzle 17 is arranged.
  • the sensor will take into account the transport time Blower nozzle 17 actuated and the compressed air pulse triggered transports the contaminated part of the fiber material into the collecting container 18.
