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 Ausscheidemessem, which are arranged on a partial circumference of the roller at intervals.
  • Ausscheidemessem 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 to 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 away from the actual delivery area of the opener roller, 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. It is going to leave generates an air accumulation of detected foreign fibers in the area in front of a separating knife, 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 roll.
  • 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 detected on the drum foreign fibers directed approximately tangential to the roller blast air flow is generated, wherein the resulting located in the region of the Blas Kunststoffstromes fibers are lifted from the roll surface and fed to a disposal space via the resulting negative pressure on the roll surface ,
  • 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 by means of a plurality of adjacent sensors or a camera are sequentially placed in a special manner via subsequently attached blast nozzles arranged in rows Blown container. 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 matter is still easily carried out. 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 ensures that in the area of the cleaning stage, the fiber material can be guided over a correspondingly large cleaning surface, while for the further transport of the cleaned fiber material over the funnel-shaped channel, this can be brought together on a narrow, 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 previously claimed sensors can be formed from one or more cameras. Furthermore, individual sensors for monitoring are possible.
  • the sensor is preferably associated with a lighting device.
  • the separation device may be formed from adjacent blast nozzles, which are sequentially controlled via the sensor by a control unit.
  • Fig. 1 shows a cleaning stage 1, which is provided with a ⁇ ffnerwalze 4 and with Abscheidemessern 5, which are arranged over a portion of the circumference of the ⁇ ffnerwalze one behind the other.
  • the fiber good which is conveyed in a flake form by a transport air stream, the cleaning stage 1 is fed via a feed shaft 6.
  • the fiber material can be delivered from an upstream cleaning stage, in which, for example, a rough cleaning is performed.
  • the cleaning stage 1 shown is then connected downstream of the "coarse cleaner” as a "fine cleaner”.
  • the fiber material enters the area of action of a ⁇ ffnerwalzencrues 8.
  • the fiber flakes are opened further and dispensed metered down, the fiber material passes into the nip of a wire roller 10 and a transport roller 11.
  • the screen roller 10 and the transport roller 11 are connected to a drive not shown in detail, which drives them in the opposite direction of rotation, whereby the fiber material supplied from above is passed between the two rollers.
  • the transport roller 11 has a smooth surface, while the screen roller 10 has a perforated surface, wherein the interior of the screen surface is connected to a schematically shown channel 12, in which most of the transport air of the fiber air mixture is discharged.
  • the fiber material guided between the rollers 11 and 10 is still in flake form and enters the feed channel S of a subsequent feed roller 14, which cooperates with a feed trough 15.
  • the fiber material Due to the funnel-shaped merging of the fiber material between the feed roller 14 and the feed trough 15, the fiber material is compressed and transferred in the region of the feed lip 16 to the schematically indicated clothing 7 of the revolving opener roller 4.
  • the fiber flakes are opened further, as a result of which the impurities entrained in the fiber-material flow as dirt, Trashmaschine, etc. can escape from the Fasergutstrom by the centrifugal force on the opener roller 4 to the outside.
  • a tray plate 18 is arranged, via which the cleaned fiber material is fed to a discharge opening 20.
  • a channel 22 is arranged, via which air L is supplied from an air pressure source not shown in detail. The air L is fed approximately in the tangential direction to the opening roller 4 and supports the detachment of the fiber material located in the clothing 7 of the offener roller 4.
  • the air L could also be supplied directly from the ambient air, which is sucked in by a negative pressure generated in the transport channel 26.
  • the fiber material is discharged to a delivery region or into a delivery tube 24 and transferred by the action of the air L into a subsequent transport channel 26. From this transport channel 26, for example, the fiber material is supplied to either a further cleaning stage or a subsequent feed chute of a carding machine.
  • the discharge pipe 24 is provided on its first portion 28 with a constant cross-section whose width B corresponds approximately to the length of the opening roller 4.
  • the section 28 of the discharge pipe 24 opens into a in the transport direction T tapered, second section 30 (called “hopper"), which opens into the transport channel 26.
  • two opposite CCD cameras 32, 32 'and 33, 33' are mounted in pairs behind the dispensing opening 20, each of which is integrated with a transparent window 35, 36 which is integrated in the subsection 28 Monitoring the output of the cleaning stage 1 fiber material.
  • the section 28 are also attached background strips 38, which are positioned to the respective camera 32, 32 'and 33, 33' on the opposite side of the channel.
  • the color of the background strip 38 corresponds to the set parameters for the fibers, so that the cameras do not respond when the partial section 28 is empty.
  • a similar device is for example from WO-96/35831 refer to.
  • the respective cameras 32-33 'lighting fixture 40 are assigned, which provide sufficient illumination of the guided past the cameras fiber material.
