  • An object of the present invention is to provide a quality control system and method which improves the efficiency of a spinning mill.
  • Another object of the present invention is to provide a quality control system and method to obtain maximum production for a given minimum level of contamination.
  • the present invention includes a quality control system for a production unit comprising a plurality of different processing machines which carry out processing on intermediate product and which operate sequentially and optionally in parallel; comprising:
  • the present invention includes a method of a controlling quality in a production unit comprising a plurality of different processing machines which carry out processing on an intermediate product and which operate sequentially and optionally in parallel; the method comprising the steps of:
  • the second machine may lie downstream or upstream of the first machine in a sequential processing line.
  • the system and method may apply to a spinning mill.
  • the processing machines may include, but are not limited thereto, a bale opener, a mixer, a cleaner, a carding machine or any other machine in the opening line, a draw frame, a flyer, a ring spinning machine, an open end spinning machine, a winder, etc.
  • the present invention includes a quality control system for a production unit; comprising:
  • the present invention includes a method of a controlling quality in a production unit, the production unit comprising a first processing machine for carrying out a first processing step on an intermediate product, a second processing machine for carrying out a second processing step on an output from the first machine, the second machine having a quality control device for a quality parameter, and a third processing machine also for carrying out the second processing step on an output of the first machine, the third processing machine not having a control device for the qulaity parameter, the method comprising the steps of: monitoring the quality of the intermediate product in the first processing machine; recording the quality values output by the monitoring step on the first machine; and selecting one of the second and third machines for processing the output of the first machine based on the recorded quality values for that intermediate product.
  • the production unit may be a spinning mill. If the quality data from the first machine are good (acceptable) the selection may be of the third machine. The decision to select one of the second and third machines may also be based on other data obtained before processing in the first machine. For example, a "bad history" may be taken into account so that although the results of the quality measurements in the first machine are very good, the second machine is selected as poor results are still feared because of the bad history.
  • the present invention may include a method for controlling a spinning mill comprising a plurality of different processing machines which carry out fiber processing on fiber product and which operate sequentially or in parallel, the fiber processing producing different fiber structures at the exit of different machines; comprising the steps of: detecting foreign fibers or material at at least one of the processing machines; and processing the results of the detecting step to optimize the operation of at least some of the other processing machines.
  • the present invention also includes a control system for controlling a spinning mill comprising a plurality of different processing machines which carry out fiber processing on fiber product and which operate sequentially or in parallel, the fiber processing producing different fiber structures at the exit of different machines; comprising: a detector of foreign fibers on at least one of the processing machines; a processor for processing the results of the detecting step and to optimize the operation of at least some of the other processing machines.
  • the optimization may include downstream control modifications, e.g. selection of certain of the processing machines in preference to other machines.
  • the optimization may include selecting processing machines with foreign fiber detectors or selecting those without such detectors.
  • the optimization may also include upstream control modifications, e.g. changing the settings of foreign fiber detectors on earlier machines, or removing some bad material from production.
  • the optimization may include one or more of the following decisions as well as the relevant action derived therefrom:
  • Fig. 1 is a schematic layout of a spinning mill with an automatic transport system in accordance with an embodiment of the present invention.
  • Fig.2 is a schematic layout of a spinning mill with centralized computer system in accordance with an embodiment of the present invention.
  • Fig. 3 is a schematic layout of a spinning mill with an automatic transport system and a centralized computer system in accordance with an embodiment of the present invention.
  • Fig. 4 is a block diagram of a global control system in accordance with another embodiment of the present invention.
  • Fig. 5 is a flow diagram of a downstream machine selection process in accordance with an embodiment of the present invention.
  • Fig. 6 is a flow diagram of a control system in accordance with an embodiment of the present invention.
  • the bales are put together in a more or less random manner.
  • the bale openers pick raw cotton flocs from their surface. This is the first position in the spinning mill where a detection and removal of the contaminants has been considered. if the system detects a contaminant the bale opener is stopped and an alarm sounded. Somebody has to inspect and remove the contaminant and start the bale opener again. This process does not influence the material flow as long as the time is short enough otherwise the cards may run out of material. To prevent the cards running out of material it is necessary to ignore the alarms sometimes. Usually, the bale opener is allowed unhindered to pick up the contaminants and feed them, together with the good quality cotton, towards the various stages of opening and blending.
  • blowroom itself is quite capable of separating certain contaminants, for example especially small sized foreign matter will be separated. Larger contaminants are more likely to remain in the system all the way to the card where they are almost completely fragmented.
  • Contaminant detection is known between the bale opener and the card entry.
  • the performance of these known systems can be tuned to some extent by the appropriate selection of their position along the material flow.
  • contaminants can hide inside or between cotton tufts thereby decreasing detection efficacy.
  • Contaminant is usually removed by a clap or pneumatic injection valve. Foreign material sitting in cotton clusters cannot be detected. As the system also removes good material (due to the removing system and/or false detection) a high efficiency correlates with high loss. Typical values are 80% efficiency with moderate loses.
  • the foreign fibers exit the card not as a uniform stripe but rather as a "comet”: a rather pronounced first part (the head) followed by the "tail”, which can, as extend over several meters.
  • the tail On the draw frame entry, first passage, the tail enters first. This imposes strong stability demands on any detection system installed there, as well as high sensitivity requirements since the tail must be recognized typically within one meter in order to allow timely stoppage.
  • each rotor may be provided with a foreign fiber detector guaranteeing the quality of this intermediate product. This detector detects and evaluates each foreign fiber.
  • the contaminant is removed automatically by stopping the machine, removing the contaminant, splicing the yarn together and starting the machine again. But the quality of the yarn is influenced (e.g. strength). As this is the last machine in s spinning mill this influence directly the output of the spinning mill thus the number of cuts should be kept to a minimum. Systems at other positions in the spinning mill do not influence the output as long as enough e.g. containers are available (buffer-function).
  • the inspection also represents an end inspection of the material.
  • the one type is the individual foreign fibers.
  • the other type is referred to as swarm, cluster or flock. These are the offspring of the rag that has survived the journey from raw cotton bale to open-en breaker without being detected.
  • foreign fiber detection systems installed in the blowroom are capable of handling somewhere between 650 and 1200 kg/hour.
  • the point at which work in progress becomes low quality may vary.
  • the quality labeling occurs once the work in progress has achieved a relatively well defined form, e.g. as a sliver at the carding stage or during or after drawing, or as yarn after spinning.
  • a relatively well defined form e.g. as a sliver at the carding stage or during or after drawing, or as yarn after spinning.
  • Fig. 1 is schematic layout of a spinning mill machine park with which the present invention may be used.
  • the park includes a plurality of different fiber processing machines 2, 4, 6, 8, 10 such as a bale opener, a mixer, a cleaner, a carding machine, a draw bench, a combing machine, a texturing machine, an open end spinning machine, a winder, a flyer, etc.
  • a quality control device 12, 14, 16, 20 is provided.
  • the quality control devices 12, 14, 16, 20 may include a foreign fiber detector and optionally a clearer and/or alarm.
  • Intermediate product may be delivered to the machines 2, 4, 6, 8, 10 by an automatic delivery system 21, 23, 25, 27.
  • Intermediate product such as a can, or bobbin 15 may be transported in trays 13.
  • Intermediate product, e.g. cans, bobbins, may be stored in an unloading area 23.
  • Raw product, e.g. cotton bales, and completed product, e.g. bobbins, may be stored in a warehouse 21.
  • a quality label 17, 19 is associated with an intermediate product (work in progress) which defines some quality characteristics of the product, such as the number and/or position and/or types and/or colors and/or size and/or length of foreign fibers present in fleece, web, a sliver or yarn.
  • the information which can be stored may be the intensity of the contaminant, its length, its color and its position within the intermediate product (length in meters from the beginning).
  • the level of contamination may be summarized in a contamination index, i.e. a single value calculated from the quality parameters measured in accordance with an appropriate algorithm.
  • label is meant in its broadest sense and may include remote sensing memory devices in general such as bar-codes or remote readable memory cards, as well as contact reading devices. Where physical labels are used, they are preferably machine readable. For example, the cans may be marked e.g. at the end of processing at the card with a code, including all the information of the contaminants. The information can be recorded as a bar-code or in an electronically read/write device (e.g. small passive chip on the cans with small RAM, which can be accessed by radio frequency devices). The quality information may be alterable in the label. For example, with remote reading memory cards including E 2 PROM's the stored information may be altered or updated or corrected at a later stage.
  • the label 17, 19 may attached to work in progress 15 or may be attached to a tray 13 carrying the work in progress.
  • the automatic transport system may also be adapted for directly selecting the intermediate product, e.g. a can, as either good quality and bad quality and influencing its transport to the machines further down the processing line (draw frames and/or OE spinning machines).
  • the automatic transport system may have a reader and processor 11.
  • Processor 11 preferably includes sufficient local intelligence to decide whether an intermediate product is high or low quality.
  • This device 11 reads the label 17, 19 and decides based on the read data whether the intermediate product should be classified as one of a plurality of qualities, e.g. high or low quality.
  • the reader 11 may then update the records for the intermediate product 11 without deleting previous data.
  • the automatic transport system may then decide to move the low quality intermediate product to machines processing low quality product.
  • Such a machine 8 may have no quality control device for foreign fibers (because the quality is not important).
  • the automatic control system may decide that the intermediate product 15 can be improved or that it is reasonably high quality.
  • the automatic transport system may transport the intermediate product 15 to a machine 2, 4, 6, 10 with a foreign fiber detection system 12, 14, 16, 20.
  • the automatic transport system may decide that, as only a few foreign fibers exist in the intermediate product it can be safely moved to a machine 8 without a foreign fiber detection device. Even if a foreign fiber is present, it may be removed in machine 8 if its position is known accurately. In this case the machine 8 may be stopped at the appropriate length and the foreign material removed.
  • FIG. 5 A method of selecting a downstream machine (downstream or feed forward control) is shown schematically in Fig. 5 which will be described with reference to a foreign fiber detector at the exit of a carding machine as an example.
  • the label on the can is read including the running contamination index (RCI).
  • the RCI is a weighted average of the contamination indices from previous machines. The RCI therefore gives a measure of the "history" of the intermediate product up to this point.
  • step 62 the intermediate product (IP) is processed on the machine and the foreign fiber intensity, position, type etc. is recorded onto the label. From these values a current contamination index (CCI) is calculated based on a suitable algorithm.
  • CCI current contamination index
  • step 64 it is examined if the CCI is above a certain first upper threshold (indicating poor quality). If yes in step 64, it is then examined in step 65 if the RCI is above a second upper threshold (indicating general poor quality). If yes in step 65 the IP is directed to the low quality line, e.g. a machine without a foreign fiber detector and the label is updated to classify the material as low quality. If no in step 65 (indicating general good quality) it may be decided to try and improve the quality so the IP is directed to a machine with a foreign fiber detector and the IP is qualified as of intermediate quality.
  • step 64 it is determined in step 66 whether the RCI is above the second threshold (indicating general poor quality). If yes in step 66 it is decided that the material may still be of poor quality because of a poor history and the IP is sent to a machine with a foreign fiber detector. If no in step 66 (indicating general good quality) the IP is labeled as good quality and is sent to a machine with no foreign fiber detector.
  • the quality of the intermediate product may be first identified at the later machine.
  • a reader and processor 22, 24, 26, 28, 30 may be provided at each machine 2, 4, 6, 8, 10 for reading the label 17, 19 and deciding what should be done based on the data recorded.
  • the reader processor on the machine may be adapted to force the relevant machine to stop forcing the operator to change to a new intermediate product or to ask for instructions.
  • this latter procedure is also suitable for a spinning mill without any automatic transport system.
  • the intermediate product 15 is delivered to the machines 2, 4, 6, 8, 10 by some other means, e.g. by fork lift truck, and the label 17, 19 is then read by the local reader and processor 22, 24, 26, 28, 30. Further, processing of each intermediate product 15 is controlled by the reader and processor 22, 24, 26, 28, 30 as described above.
  • the reader and processor 22, 24, 26, 30 may also be adapted to write quality data delivered by quality control device 12, 14, 16, 20 to the respective label 17, 19 of any finished intermediate product 15 doffed from the respective machine.
  • the settings of the foreign fiber detection units 22, 24, 26, 30 at a processing machine 2, 4, 6, 10, e.g. the draw frame can be adjusted by the reader and processor 22, 24, 26, 30 based on the quality information associated with the intermediate product 15 to be processed. For example, a contaminant exits a carding machine like a comet. On entering the draw frame in reverse direction the settings of the foreign fiber detector at the draw bench must be set to very sensitive to detect the "tail". Knowing the approximate position of the contaminants the settings of the detection system on the drawing frame are adapted for optimally detecting the 'tail' of the contaminant.
  • This change of setting of the foreign fiber detecting device on the draw bench need only be done close to the position of the contaminant, the position of the contaminant being already stored in the label associated with the can being processed. This avoids running the draw bench with the foreign fiber detector continuously set at a very sensitive level (risk of false alarms and unnecessary machine outage).
  • the reader processor 22, 24, 26, 30 can activate a pre-alarm in order to inform the worker that the machine will stop soon.
  • marking/selecting the intermediate product 15 at each stage up to the open end spinning machine may be used to adjust the settings of a later or earlier detection system and/or marking the final bobbin with the 'history' of yarn production.
  • a flow diagram of a process in accordance with this embodiment is shown in Fig. 6 which will be described with reference to a foreign fiber detector at the exit of a carding machine as an example.
  • the label on the can is read including the running contamination index (RCI).
  • the RCI is a weighted average of the contamination indices from previous machines. The RCI therefore gives a measure of the "history" of the intermediate product up to this point.
  • the intermediate product (IP) is processed on the machine and the foreign fiber intensity, position, type etc. is recorded onto the label. From these values a current contamination index (CCI) is calculated based on a suitable algorithm.
  • step 75 a flag is incremented in step 75.
  • the flag may be reset every suitable time period.
  • step 76 it is determined if the CCI is above a certain threshold. If yes in step 76 this is an indication of general bad quality.
  • step 77 it is determined if the value of the flag is above a certain number N 1 , e.g. 3. If yes in step 77 it indicates that several bad quality cans are being processed and bale tracing in the blow room is carried out in step 78 to remove a suspected poor bale. If no in step 76 or step 77 this may indicate that the upstream detectors are not set fine enough and the foreign fiber detectors upstream of the card are increased in sensitivity in step 79 to remove more contaminant.
  • step 80 it is determined in step 80 whether the RCI is above a threshold. If yes in step 80 the processing is continued as normal. If no in step 80 it is determined in step 81 if any foreign fiber has been determined in this can. lf yes in step 81 then the next downstream detectors and machine are alerted to remove this contaminant in step 82. In no in step 81 a flag is increased by one in step 83. The flag may be reset as soon as the answer to step 81 is yes. In step 84 it is determined if the flag is greater than a certain number, N 2 , say 20. If yes in step 84 this means that very high quality material is being processed. In step 85 the detectors upstream are lowered in sensitivity to remove less good material. If no in step 84, the can is processed normally.
  • each can processed on a carding machine may be given a number.
  • information relating to foreign fiber content may be transmitted from the foreign fiber detector on the carding machine to a centralized computer and stored there with a link to the can number.
  • the quality information can be read from the computer by inputting the can number.
  • the machine park 2, 4, 6, 8, 10 of Fig. 1 may include a centralized computer system 31, 33, 35, 37.
  • Each intermediate product 15 is provided with a label 17 or 19 as described with reference to Fig. 1, e.g.
  • each intermediate product is marked with a passive code (e.g. number, fixed BAR-CODE on a can or bobbin) which identifies it. If all machines are linked to a central unit, each intermediate product can be identified at each machine or other places in the spinning mill with a simple read device. This label only needs to contain a reference number for the relevant intermediate product. This number is read by a reader and processor 32, 34, 36, 38, 40 at each machine 2, 4, 6, 8, 10. The local processor 32, 34, 36, 38, 40 may retrieve data relating to the reference number from a centralized computer 31 having a processor 33 and non-volatile read/write memory 35.
  • a passive code e.g. number, fixed BAR-CODE on a can or bobbin
  • the central computer 31 may download the respective data from its memory 35 on receipt of the reference number as well as a number defining the relevant machine 2, 4, 6, 8, 10. Based on the received information the processor 33, or the reader and processor 32, 34, 36, 38, 40 may decide the appropriate action which may be the same as described for the system according to Fig. 1, i.e. stop the machine and reject the product, change the settings of the foreign fiber detection unit on the machine or move the intermediate product to another machine.
  • the reader and processor 32, 34, 36, 38, 40 on each machine 2, 4, 6, 8, 10 receives operating data from that machine including, where available, information with respect to foreign fiber detection from a foreign fiber detector 12, 14, 16, 20.
  • This data is transmitted to central computer 31 via bus 37 and this information is stored in the memory 35 of computer 31 with a link to the reference number of the intermediate product and to the machine on which it was processed, thus updating the history.
  • Fig. 3 is a schematic representation of a further machine park of a spinning mill with which the present invention may be used. It shows the combination of a centralized computer/foreign fiber detection system described with reference to Fig. 2 and the automatic delivery system described with reference to Fig. 1.
  • the functions of the reader and processors 22, 24, 26, 28, 30 of Fig. 1 and 32, 34, 36, 38 and 40 of Fig. 2 are now incorporated into reader and processors 42, 44, 46, 48, 50 respectively.
  • the recorded quality data in the label may not only be used to modify the settings of a quality control sensor on a processing machine either downstream or upstream of the machine where the data was recorded but also to select the next processing machine further downstream in the processing based on the stored information in the label.
  • normally contaminants occur in clusters.
  • the settings of the foreign fiber detection devices in the upstream machines such as the opening line can be adjusted in order to detect more contaminants (with the disadvantage of loosing good material but with the advantage of greater efficiency downstream).
  • the stored quality information in the labels may be used for tracing purposes and action taken.
  • the relevant cotton bale can be determined from where the contaminant originates and this bale can be removed (based on the fact that normally there exists contaminated bales with many contaminants and contaminant free bales). if the card is not stopped or a doffing forced, tracing and/or control of the further processing of the can is necessary, i.e. rectifying action may be taken at a later machine. This may be done by using the information in the label.
  • the functions of the control system in accordance with the present invention may be partitioned between the two to obtain good efficiency and fast response. There may be a partitioning between local sensing, reading at machine level, and more strategic decisions taken at a higher level in the central computer 31.
  • Each system 12, 14, 16, 20 may be able to remove the contaminant automatically with minimal interruption of the material flow (e.g. in the blow room), or by stopping the machine and removing the contaminant automatically (short interrupt of the material flow e.g. at a winder or OE spinning machine) or by stopping the machine and alarming a worker to inspect and removing the contaminant.
  • the systems described with reference to Fig. 2 and 3 are typical installation positions of such systems but these can be easily transferred to other positions (e.g. combing machine, flyer, mixer, etc.).
  • Each Detection/Removing system with its own processing unit e.g. PC or u-controller
  • the central unit or local units may decide:
  • the decision(s) may be made dependent on at least one of the following criteria:
  • the machines 12, 14, 16, 18, 20 in the machine park may be formed into smaller groups, e.g. linked to each other, to form a sub-group of one of the systems described with reference to Figs. 1 to 3.
  • the sub-system may have its own local computing power in order to get a faster response for changes within the sub-group.
  • Within the sub-group system there may only be control of the machines in the sub-group. Control outside the sub-group reverts to a centralized computer in a hierarchical manner.
  • the foreign fiber detection systems associated with respective machines may be linked together to form a single unit with associated electronic processing machines running computer programs capable of finding the optimum operating points and conditions of each sub-system.
