Definitions
- the invention relates to a method for detecting and removal of foreign matter into fibrous material according to the preamble of claim 1, as well as a Device for the practical implementation of a Such method according to the preamble of claim 7.
- Such methods and devices are primarily in spinning mills for cleaning Raw cotton used.
- Raw cotton is common with Foreign matter such as e.g. Lacing, jute or other Meshes, plastic parts, etc. interspersed, which in the spinning process like the cotton fibers themselves to be processed into yarn and which only with one considerable effort can be removed again.
- the cleaning fiber material can also be used in other processing processes, such as. in the processing of mineral, synthetic or animal fibers Role-play.
- the invention consists in a device of the above to create said type, which saves space in a production line can be installed and the ever after application, the use of different detection methods allowed.
- This object is achieved according to the invention solved with a method that the Features in claim 1.
- the object is with a device with the features of claim 7 solved.
- the fiber material is passed the sensor field on a presentation track, which is inclined to the vertical by 0 ° to 50 °.
- the flow in the presentation channel can open be achieved in different ways. This is conceivable Blow in air at the top of the presentation channel with the help of a fan. But it can too maintain a negative pressure after the presentation channel can be obtained, e.g. by the pressure side of a fan via a suction nozzle with the lower end of the Presentation channel is connected. It is after The Venturi principle creates a negative pressure. The negative pressure but can also be generated by a fan be on the transport line for onward transport the fibers is arranged, in addition. Air is sucked in after the presentation channel. Preferably becomes the continuous flow in the presentation channel cumulatively upright by various means get as uniform a speed as possible to achieve. By fixed or adjustable Throttling can be over the entire channel cross section maintained uniform air velocity become. It is also conceivable, the throttles or the inserted Fans mechanically or electronically to regulate.
- the flow can be under the presentation channel be redirected, with the elimination the contaminated subset in the area of the direction change or immediately afterwards.
- the inertia The foreign substances will become more targeted Exhaustion optimally utilized. An excretion but is also before the deflection in the vertical area possible.
- the presentation channel arranged a distribution device for the uniform metering of the fiber material in the Presentation channel. It is conceivable, directly to arrange a condenser over the presentation channel, the channel possibly via a cellular wheel or the like fed. But it is also possible over the Presentation channel to arrange a hopper, in always kept a certain amount of fiber in stock becomes. The metering takes place from the hopper About discharge or. Opening rollers. An optimal speed the fiber material can be largely also by the tangential velocity of the Cell wheel or the opening rollers can be achieved. The Final speed is thus by mechanical and defined pneumatic means in combination
- the sensor arrangement but also still have sensors that respond to other parameters react, such as to different density, on different substances, etc.
- sensors that respond to other parameters react, such as to different density, on different substances, etc.
- the sensor arrangement additionally has at least a sensor that is in the range of ultraviolet or infra-red or near-infrared works. With such Sensors can also detect foreign bodies, which have approximately the same color as the Cotton fibers, however, made of a different material consist.
- a particularly advantageous construction of the device results if these at least one feed module, has a sensor module and a separation module, between these modules optionally further Modules are installable.
- the modular design allows on the one hand a simple installation and maintenance the device. On the other hand, but also later additional components are incorporated, such as e.g. additional sensors etc.
- the device shown in Figures 1 and 2 has a housing 22 in which a vertical, arranged in cross-section rectangular presentation channel 1 is.
- the two parallel side walls 7, T of the Presentation channels are as transparent slices trained, but could possibly also have a filtering effect exercise for certain wavelengths of light.
- On Both sides of the presentation channel are lighting fixtures 3 arranged.
- the sensor arrangement consists of the two CCD cameras 2, 2 ', the presentation channel off Space saving reasons however over the two mirrors 8, 8 'apply indirectly.
- the optical planes 27, 27 ' are arranged slightly offset from one another. Seen from the observation side respectively There is a background strip behind the presentation channel 6 arranged in the row level, the set Parameters for the fibers corresponds, so that the camera is not synonymous with empty presentation channel responds.
- an intermediate module 26 is arranged whose channel cross-section however, it is the same as the presentation channel.
- This intermediate module serves on the one hand as a fall and could on the other hand also with other sensors, such as Metal detectors or infrared sensors be fitted.
- the air flow in the presentation channel is generated by a fan 4, the pressure side with an air inlet module 5 is connected. This module could be omitted if the flow is exclusive is generated in other ways. additionally the flow can be assisted by one Fan not shown here, after the Presentation channel arranged in the transport line is and primarily serves the material transport. About an air inlet duct 16 is thereby additional air sucked. The suction effect thus produced evidently causes a negative pressure in the presentation channel.
- a Blasdüsenance 17 arranged, over one Ejection opening 18 leading to a collecting container 20th leads.
- a rotating Cell wheel 19 may be arranged to prevent backflow.
- the blast nozzle strip 17 also the cellular wheel 19 is rotated.
- the ejection opening and the tuyere could also in the vertical shaft area immediately below the Presentation channel be arranged. Instead of the cell wheel could be provided a short-opening flap become. If the pressure conditions allow it, the discharge opening does not have to be closed at all become.
- the cleaned fibers are over the Transport pipe 21 discharged and get to the next Machine.
- the device is constructed in modular design and includes a delivery module 23, a sensor module 24 and a separation module 25. These modules form the basic equipment. You can exchange or be supplemented.
- the partially contaminated cotton fibers thus arrive from the direction of arrow a first in the condenser 9, then fall down against the presentation channel 1, focusing on the desired conveying speed to be brought. In optimal presentation form the fibers then pass the sensor field, where color different foreign bodies detected become. Exactly matched to the remaining drop distance is at a signal on the sensor array the blast nozzle bar is activated with compressed air.
- the nozzle bar can work linear or punctiform, so that only a specific segment of the width the flow can be eliminated. This Of course, a corresponding evaluation the sensor signals on the sensor assembly ahead.
- FIG. 3 shows an alternative embodiment, in which the presentation channel 1 under a Angle of slightly less than 45 ° inclined to the vertical is. Otherwise, however, the sensor module 24 is approximately the same structure as in the embodiment according to Figure 1.
- the metering of the fibers from the condenser 9 also takes place via a cellular wheel 13.
- the admixture of air through the fan 4 takes place here at an angle to the conveying direction of the flakes.
- the ejection opening 18 is opposite to the Blasdüsenance 17 in the Vertically arranged and leads without a cell wheel or the like directly to the collecting container 20.
- the passing on the flakes in the transport tube 21 via a open funnel 14, being at the entrance of the funnel Room air is sucked in.
- WO 89/01832 is a device for sorting Fiber material in a pneumatic conveyor line has become known.
- the material is thereby successively at a monitoring station and at a lateral opening in the delivery line past. From arranged opposite the opening nozzles a gas pulse can be triggered across the channel. As soon as the monitoring station determines a foreign substance to be eliminated, this is through the opening into a substantially gas-tight chamber blown out.
- EP-A-285 602 discloses a method and an apparatus for detecting and removing foreign substances from raw cotton known. To detect foreign fibers is thereby the raw cotton irradiated with X-rays, with density fluctuations can be determined. To this end The cotton material must be dammed up in such a way that between them lying cavities are eliminated and a largely continuous flow of material with homogeneous surface density arises. The excretion of foreign substances is carried out by Blow out by means of a compressed air nozzle.
