Definitions

  • the invention relates to a device for detecting and eliminating foreign substances from a fiber material which is fed via feed elements of a cleaning stage, wherein the fiber material is guided by means of a ⁇ ffnerwalze via one or more Abscheidesch and delivered to a subsequent conveyor channel.
  • a ⁇ ffnerwalze which is occupied with pins or hooks, cooperates with Ausscheidemessern which are arranged on a partial circumference of the roller at intervals.
  • Ausscheidemessern which are arranged on a partial circumference of the roller at intervals.
  • the fiber is discharged via a shaft and two feed rollers to the surface of the ⁇ ffnerwalze.
  • sensors are proposed which are arranged opposite the surface of the opening roller. These are color sensors, which are arranged over the working width of the roller.
  • the color sensors determine a color deviation of the foreign fibers relative to the normal fiber and are connected to an evaluation electronics.
  • the surface of the opening roller may have a metallic shiny or white surface.
  • the cleaned fiber material is delivered to a suction line, in which a discharge device is integrated.
  • a discharge device is integrated.
  • using the signals of the sensors are operated time-displaced in a certain time interval hinged flaps, which supply the fiber material provided with foreign fibers a disposal line.
  • the ejection device shown is relatively far from the actual delivery of the Opener roller removed, so that a larger fiber mass must be discharged, so that in this process, the detected foreign fibers are removed.
  • the circumferential tips of the set, or the pins adversely affect an exact detection of foreign fibers. This means that the foreign fibers, which are located directly in the area of these tips, may not be detected by the sensors as foreign fibers, especially as the process pattern of the clothing tips in the evaluation electronics is filtered out.
  • the fiber material is in the transfer to the opener roller as a relatively compact fiber fleece, which may not be detected inside, directly guided on the drum circumference foreign fibers.
  • an opening roller known, which also cooperates with Ausscheidemessern.
  • an air accumulation is generated, wherein the interspersed with foreign parts fiber material is lifted from the roller and transferred to a disposal facility.
  • the monitoring for foreign fibers also takes place on the roll surface of the opening roller.
  • many good fibers are also deposited in this device when discharging foreign fibers.
  • the DE-A1-198 47 237 shows a similar device, wherein for the separation of the foreign fibers detected on the drum, an approximately tangential to the roll directed Blas Kunststoffstrom is generated, wherein the resulting negative pressure on the roll surface in the region of the Blas Kunststoffstromes located fibers are lifted from the roll surface and fed to a disposal space.
  • it is a ⁇ ffnerwalze, which has the task of further open the supplied fiber, or termeschliessen into smaller fiber flakes. An additional cleaning of the fiber material of contamination is not provided here. Even with this arrangement, there is the danger, as described above, that not all foreign fibers in the fiber material guided via the opener roller can be detected or removed.
  • the opening device consists of one or two feed rollers that deliver the fiber material supplied via a shaft to a high-speed opening roller.
  • the fiber material further dissolved by the opening roller is fed in free fall to a downwardly guided shaft in which a device for detecting and separating foreign substances is mounted.
  • the foreign substances detected via a plurality of juxtaposed sensors or a camera are blown out sequentially into a special collecting container via subsequently attached blast nozzles arranged in rows. These nozzles are controlled via a control unit, which is connected to the sensor.
  • the blowing nozzles are very often controlled via the controller for blowing out.
  • the blowing cone of the blast air flow must have an appropriate size so that the detected foreign substances are safely eliminated.
  • the invention thus has the object to avoid the disadvantages of the prior art described, in order to obtain an optimal means for the targeted elimination of foreign substances and the elimination of good fibers is minimized.
  • This object is achieved in that the detection and separation device for the foreign substances is arranged directly in the discharge area of the cleaning stage.
  • the term "delivery area” is to be understood as meaning the area directly at the discharge opening of the cleaning stage or also the area which follows directly after the discharge opening. With this device it is ensured that the detection device (sensor) a Fasergutmasse is supplied in the free flake stream, from which conventional contaminants, such as Trash parts, dirt, dust and the like have already been deposited at the upstream cleaning stage in a conventional manner substantially. In addition, the foreign substances still to be detected in an open flock flow easier to detect, as between the set of an opening roller. By attaching directly in the delivery area of the cleaning stage, the fiber air flow has a speed at which the detection of foreign substances is still easily feasible. By the elimination of entrained in the fiber material contaminants already at the cleaning stage, the subsequent detection and separation can concentrate on the foreign matter, which are not deposited due to their physical property at the upstream cleaning stage.
  • the discharge area - seen in the conveying direction - is designed as a tapered and funnel-shaped channel, which opens into the delivery channel. This will ensures that in the area of the cleaning stage, the fiber material can be guided over a correspondingly large cleaning surface, while for further transport of the cleaned fiber material on the funnel-shaped channel this can be merged on a narrower, tubular transport channel. This makes it possible to keep the energy required for the transport of fiber to a minimum.
  • the detection and separation device is mounted on the funnel-shaped channel.
  • the conveying speed of the fiber material in the funnel-shaped channel is lower than in the subsequent conveying channel, so that problem-free detection and separation of foreign substances can be carried out here.
  • the discharge area is provided in a first part with an approximately constant cross section, which is followed by a funnel-shaped part, which opens into the delivery channel.
  • a channel for air supply in the delivery direction is arranged in the delivery region.
  • the detection device is arranged approximately tangentially in the discharge region of the cleaning stage at a distance from the assembly of the opening roller. This makes it possible To detect the foreign matter immediately in the field of detachment from the opening roll.
  • the senor of the opposite wall of the cleaning stage following channel in a section as an optical background, eg. B. is designed as a reflection surface for the sensor, wherein the reflection surface is arranged approximately at a right angle to the monitoring plane.
  • the reflection surface of the color of the fiber material good fibers
