Definitions
- the invention relates to a method for recognizing and eliminating of foreign substances in fiber material according to the generic term of claim 1, and a device for practical Implementation of such a method according to the preamble of claim 7.
- Such methods and devices are primarily used in spinning mills to clean raw cotton used.
- Raw cotton is often with foreign substances such as. Lacing, jute scraps or other scraps of fabric, Plastic parts, etc. interspersed, which in the spinning process like the cotton fibers themselves are processed into yarn and which can only be removed with considerable effort can be.
- One is therefore striving to remove these foreign substances to be eliminated as completely as possible in the blow room.
- the cleaning of fiber material can also be done in others Processing processes, e.g. when processing mineral, synthetic or animal fibers play a role play.
- Another object of the invention is to provide a To create device of the type mentioned, the can be built into a production line to save space and depending on the application, the use of different Detection process allowed. This object is achieved according to the invention solved with a method that the features in claim 1 has. In terms of device, the Task with a device with the features of claim 7 solved.
- the fiber material on a presentation line is particularly advantageous guided past the sensor field to the vertical is inclined by 0 ° to 50 °. In certain cases but also a certain curvature or other inclination to the vertical conceivable.
- the flow in the presentation channel can be different Way can be achieved. It is conceivable to blow air in top of the presentation channel using a fan. But it can also follow the presentation channel Negative pressure is maintained, e.g. by the print page a fan via a suction nozzle with the lower end of the presentation channel. It is after Venturi principle creates a vacuum. The negative pressure can but can also be generated by a fan on the Transport line arranged for the further transport of the fibers is, with additional air after the presentation channel is sucked in.
- the continuous flow in the presentation channel cumulatively by different Means maintained to be as uniform as possible To achieve speed. By fixed or adjustable Throttling can be uniform across the entire channel cross section Air speed can be maintained. It is also conceivable, the chokes or the fans used to be regulated mechanically or electronically.
- the flow can be diverted under the presentation channel be, the excretion of the contaminated subset in the area of changing direction or immediately afterwards he follows.
- the inertia of the foreign substances increases optimally used a more targeted elimination.
- a Elimination is also vertical before the redirection Range possible.
- One above the presentation channel is particularly advantageous Distribution device arranged for even dosing of the fiber material in the presentation channel. It is conceivable, directly above the presentation channel to arrange a condenser, which if necessary via a channel Feeded cellular wheel or the like. But it is also possible to arrange a filling shaft above the presentation channel, in which always has a certain amount of fibers in stock. The metering takes place from the filling shaft via discharge or. Opening rollers. An optimal speed of the fiber material can largely also by the tangential speed of the cellular wheel or the opening rollers become. The top speed is thus determined by mechanical and pneumatic means defined in combination.
- the sensor arrangement is electronic Line scan camera with color sensors, with which the whole Width of the presentation channel is detectable.
- the sensor field can be kept very small, which enables space-saving accommodation.
- the line-shaped scanning also allows an easier one Programming and control of the entire system and shorter Response times.
- line scan cameras also enable the lighting of the fiber material in the presentation channel in the Incident light and transmitted light to avoid shadow effects. The lighting output can be reduced and disturbing reflections can in contrast to matrix cameras can be easily avoided.
- the CCD cameras are programmed that they are within a certain tolerance range the color, brightness and saturation of the cotton fibers are set. Any change in the color spectrum outside the tolerance range is registered as a deviation and, after appropriate evaluation, a control signal produce. Foreign substances, their color within the tolerance range cannot be recognized in this way.
- the sensor arrangement can also Have sensors that respond to other parameters, such as e.g. to different densities, to different substances etc. For this purpose e.g. X-rays, ultrasound waves, electromagnetic fields etc. are used become.
- the sensor arrangement is particularly advantageous at least one sensor that is in the ultraviolet range or infrared or near infrared works. With such Sensors can also detect foreign objects that are approximate have the same color as the cotton fibers that however, consist of a different substance.
- a particularly advantageous construction of the device results if this is at least one feed module, one sensor module and has a separation module, between them Modules can optionally be installed with additional modules.
- the modular design allows easy assembly and Device maintenance. On the other hand, you can later other components are installed, e.g. additional Sensors etc.
- the device shown in Figures 1 and 2 has one Housing 22, in which a vertical, rectangular in cross section Presentation channel 1 is arranged.
- the two parallel side walls 7, 7 'of the presentation channel are as transparent panes formed, but could possibly also another filter effect for certain light wavelengths exercise.
- the sensor arrangement consists of the two CCD cameras 2, 2 ', but the presentation channel to save space Act indirectly via the two mirrors 8, 8 '.
- the Optical levels 27, 27 ' are slightly offset arranged to each other. Seen from the observation side There is a background stripe behind each presentation channel 6 arranged in the line level of the set Corresponds to parameters for the fibers, so the camera does not respond even when the presentation channel is empty.
- An intermediate module is located above the actual presentation channel 1 26 arranged, the channel cross section, however, the same is like that of the presentation channel.
- This intermediate module serves on the one hand as a drop section and on the other hand could but also with other sensors such as Metal detectors or Infrared sensors can be equipped.
- the air flow in the presentation duct is via a fan 4 generated, the pressure side with an air inlet module 5 is connected. This module could be omitted if the flow is only in a different way is produced.
- the flow can also be supported by a fan, not shown here, which after the Presentation channel is arranged in the transport line and which primarily serves to transport materials. Via an air inlet duct 16 additional air is drawn in. The so suction effect obviously causes one Negative pressure in the presentation channel.
- the device is loaded with fibers via a Condenser 9, to which a flake feed 10 leads.
- Condensers are already known per se to the person skilled in the art.
- she have a rotating screen drum 12 on which the Flakes are condensed out of the conveying air.
- the partially Exhaust air still containing dust is discharged through the exhaust air connection 11 dissipated.
- From the outside of the drum 12 fall Flocculate again and again due to the action of the centrifugal force are then through a rotary valve 13 in the shaft dosed.
- a blow nozzle bar 17 arranged, namely over an ejection opening 18, which to a collecting container 20 leads.
- a rotating cell wheel 19 can be arranged to reverse flow to avoid.
- the blow nozzle bar is activated 17
- the cellular wheel 19 is also rotated.
- the discharge opening and the blow nozzle bar could also in the vertical Shaft area immediately below the presentation channel be arranged. Instead of the cellular wheel, a flap that opens briefly. If the The discharge opening must allow pressure conditions at all not be locked.
- the cleaned fibers are transported over the transport pipe 21 dissipated and get to the next machine.
- the device is constructed and contains a modular design a feed module 23, a sensor module 24 and a separation module 25. These modules form the basic equipment. You can exchanged or supplemented.
- the partially contaminated cotton fibers thus reach from arrow direction a initially into the condenser 9, then fall down against presentation channel 1, pointing to the targeted conveying speed can be brought.
- the fibers then pass through the sensor field, whereby different foreign objects are recorded in color become.
- the blowing nozzle bar is activated when there is a signal on the sensor arrangement activated with compressed air.
- the blow nozzle bar can work linearly or point-like, so that even one certain segment separated from the width of the flow can be. Of course, this sets one Corresponding evaluation of the sensor signals on the sensor arrangement ahead.
- Figure 3 shows an alternative embodiment in which the presentation channel 1 at an angle of slightly less is inclined at 45 ° to the vertical. Otherwise, the sensor module 24, however, constructed approximately the same as in the embodiment according to Figure 1.
- the dosing of the fibers the condenser 9 also takes place via a cellular wheel 13 Air is added by the fan 4 here at an angle to the conveying direction of the flakes.
- the removal of the foreign bodies is also solved somewhat differently in the ejection module 25.
- the ejection opening 18 is opposite the blow nozzle bar 17 arranged in the vertical and leads directly to the collecting container 20 without cellular wheel or the like.
- the flakes are passed into the transport tube 21 via an open funnel 14, being at the entrance of the funnel Room air is sucked in.
