  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the description of the drawings, the same or corresponding elements will be denoted by the same reference symbols, without redundant description.

  As shown in FIG. 1, the fiber processing system 1 according to one embodiment includes a plurality of card machines 10, a plurality of drawing machines 30, a plurality of air spinning machines 50, and a controller 70.

  The card machine 10 produces a fiber bundle by carding (carding) the wrap produced by the blending cotton machine in a process preceding the card process. For example, the card machine 10 cuts a sheet-like wrap with a comb to separate fibers, and removes dust, short fibers, and the like included in the wrap. Thereafter, the card machine 10 collects and bundles the fibers remaining after the removal of dust and short fibers in parallel to generate a string-like fiber bundle (card sliver). The card machine 10 has a draft device. The draft device is provided downstream of the card machine 10, and drafts (draws) the generated fiber bundle. The draft device separates the fiber bundle to increase the parallelism of the fiber bundle. The card machine 10 stores the fiber bundle drafted by the draft device in a can (for example, a cylindrical container). The fiber bundle drafted by the draft device of the card machine 10 is transferred to the next step in a state of being stored in the can.

  The drawing machine 30 draws the fiber bundle generated by the card machine 10. For example, the drawing machine 30 drafts 6 or 8 fiber bundles together by 6 times or 8 times, straightens the fibers, and removes unevenness in the thickness of the fiber bundles. The drawing machine 30 stores the drawn fiber bundle in a can. The fiber bundle drawn by the drawing machine 30 is transferred to the next step in a state of being stored in the can.

  The air spinning machine 50 spins the fiber bundle drawn by the drawing machine 30 to generate a yarn. The pneumatic spinning machine 50 twists the fiber bundle drawn by the drawing machine 30 to generate a yarn, and winds the yarn to form a package. The air spinning machine 50 is, for example, an air jet spinning machine or an open-end spinning machine. An air jet spinning machine twists a fiber bundle by a swirling air flow to generate a yarn. The air spinning machine 50 may draft the fiber bundle by a draft section having a plurality of draft roller pairs. The open-end spinning machine separates the fibers of the fiber bundle by a combing roller or an air stream, and then twists the fibers while re-bundles them to produce a yarn.

  The controller 70 includes a processor (for example, a CPU (Central Processing Unit)) that executes an operating system, application programs, and the like, and a storage unit 72 (FIG. 1) including a ROM (Read Only Memory), a RAM (Random Access Memory), a hard disk, and the like. 3) and a communication control unit constituted by a network card or a wireless communication module. The storage unit 72 stores data or a database required for processing.

  The controller 70 is a higher-level controller that manages or controls the entire fiber processing system 1. For example, the controller 70 is configured by a central management computer of a textile factory in which the textile processing system 1 is arranged. The controller 70 communicates with the card machine 10, the drawing machine 30, and the pneumatic spinning machine 50, and manages and controls the card machine 10, the drawing machine 30, and the pneumatic spinning machine 50. The controller 70 may be composed of one device, or may be composed of a plurality of devices. When the controller 70 is composed of a plurality of devices, one controller 70 is logically constructed by connecting the plurality of devices via a communication network such as the Internet or an intranet.

  In such a fiber processing system 1, a carding step (carding step) of producing a fiber bundle from a raw material using the card machine 10, and a fiber bundle produced in the carding step are drawn using the drawing machine 30. The fiber treatment method includes a drawing step of performing a drawing step and an air spinning step of spinning the fiber bundle drawn in the drawing step using the air spinning machine 50 to generate a yarn.

  In the fiber processing system 1, the fiber bundle generated by the card machine 10 and supplied to the air spinning machine 50 passes through the drawing machine 30 only once (one pass). In the fiber processing system 1, the fiber bundles generated by the two card machines 10 are supplied to one drawing machine 30, and the fiber bundles drawn by the one drawing machine 30 are air-spun. Machine 50.

  The fiber processing system 1 may include a sliver wrap device that performs a sliver wrap process and a comber machine that performs a combing process. In this case, the fiber treatment method includes a sliver wrap step and a combing step. In the sliver wrapping process, 18 to 24 cord-like fiber bundles generated by the card machine 10 are wound into a single sheet and wound to generate a sliver wrap. In the combing process, the sliver wrap generated by the sliver wrap device is shaved with a comb to remove dust and short fibers, and the fibers remaining after the removal are aligned in parallel to generate a uniform fiber bundle. The fiber bundle generated in the combing step is supplied to the drawing machine 30.

  The fiber processing system 1 may include, instead of the air spinning machine 50, a roving machine that performs a roving process, a ring spinning machine that performs a spinning process, and an automatic winder that performs a rewinding process. In this case, the fiber processing method includes a roving step, a spinning step, and a rewinding step instead of the air spinning step. In the roving step, a roving machine is used to generate a roving from the fiber bundles drawn in the drawing step. In the spinning process, a yarn is generated from the roving produced in the roving process using a ring spinning machine. In the rewinding step, the yarn generated in the spinning step is wound by an automatic winder to form a package.

  In the fiber processing system 1, the card machine 10 includes the draft device, but the card machine 10 may not include the draft device. The fiber treatment system 1 has a one-pass configuration in which the fiber bundle passes through the drawing machine 30 once, but may have a two-pass configuration in which the fiber bundle passes through the drawing machine 30 twice, A configuration of three or more passes in which the bundle passes the drawing machine 30 three or more times may be used.

  Next, a main part of the fiber treatment system 1 will be described with reference to FIG.

  The fiber processing system 1 includes a first quality data acquisition unit 11 that acquires first quality data relating to the quality of the generated fiber bundle. The first quality data includes data on the number of NEPs included in the fiber bundle and data on the thickness of the fiber bundle. For example, the first quality data acquisition unit 11 is a sensor provided on the downstream side of the card machine 10. As the first quality data acquisition unit 11, various known sensors can be used. The first quality data acquisition unit 11 only needs to be able to acquire any one of the data on the fiber bundle nep and the data on the thickness of the fiber bundle.

  The fiber processing system 1 includes a second quality data acquisition unit 31 that acquires second quality data relating to the quality of the drawn fiber bundle. The second quality data includes data relating to the thickness of the fiber bundle. For example, the second quality data acquisition unit 31 is a sensor provided downstream of the drawing machine 30. As the second quality data acquisition unit 31, various known sensors can be used.

  The fiber processing system 1 has a third quality data acquisition unit 51 that acquires third quality data relating to the quality of the generated yarn. The third quality data includes data relating to yarn defects (slabs and / or neps) and data relating to yarn thickness. For example, the third quality data acquisition unit 51 is a sensor provided between the pneumatic spinning device and the yarn pulling-out device (a pair of a yarn storage roller or a delivery roller) in the air spinning machine 50. As the third quality data acquisition unit 51, various known sensors can be used.

  The controller 70 includes an abnormality determination unit 71 as a functional configuration. The abnormality determining unit 71 performs an abnormality determining step. In the abnormality determining step, first, it is determined whether or not the yarn generated by the air spinning machine 50 is defective. Whether or not the yarn generated by the air spinning machine 50 is defective can be determined from the third quality data acquired by the third quality data acquiring unit 51 of the air spinning machine 50. For example, in the abnormality determination step, at least one of a case where the number of small defects of the yarn generated by the air spinning machine 50 increases and a case where the thickness of the yarn generated by the air spinning machine 50 fluctuates. It is determined that the yarn is defective.

  In the abnormality determination step, if the yarn generated by the air spinning machine 50 is defective, the raw material, the card machine 10, the drawing machine 30, and the yarn machine 30 based on the first quality data, the second quality data, and the third quality data. At least one of the pneumatic spinning machines 50 in which an abnormality has occurred is determined. In the abnormality determination step, when the yarn generated by the air spinning machine 50 is defective, the raw material, the card machine 10, the drawing machine 30, and the setting data of the card machine 10 and the setting data of the drawing machine 30 are further determined. And at least one of the air spinning machines 50 in which an abnormality has occurred.

  The raw material is a raw material of the yarn generated by the fiber processing system 1. For example, the raw material is raw cotton (not limited to cotton) which has been transported by compression packing. The setting data relating to the setting of the card machine 10 includes data relating to the setting of the fiber bundle generation speed (production speed) and data relating to the setting of the removal amount of the NEP (node). The setting data relating to the settings of the card machine 10 can be acquired from the card machine 10. The setting data relating to the setting of the drawing machine 30 includes data relating to the setting of the auto-leveler of the drawing machine 30 and data relating to the drawing speed (production speed) of the fiber bundle. The setting data relating to the setting of the drawing machine 30 can be acquired from the drawing machine 30.

  The auto-leveler is a system that adjusts the draft speed in the drawing machine 30. Specifically, one of the most upstream draft roller pairs of the drawing machine 30 is provided so as to move with respect to the other depending on the thickness of the fiber bundle. The thickness of the fiber bundle is detected based on the displacement amount. When a thick fiber bundle is inserted, the speed of the most upstream draft roller is increased. When a thin fiber bundle is inserted, the speed of the most upstream draft roller is reduced.

  In the abnormality determination step, when the yarn generated by the air spinning machine 50 is defective, the cause of the abnormality that has occurred is estimated based on the first quality data, the second quality data, and the third quality data. In the abnormality determining step, when the yarn generated by the pneumatic spinning machine 50 is defective, the cause of the generated abnormality is estimated further based on the setting data of the card machine 10 and the setting data of the drawing machine 30.

  In the abnormality determination step of the present embodiment, as described later, when the yarn generated by the air spinning machine 50 is defective, the abnormality part and the estimated abnormality are determined using the abnormality determination map M (see FIG. 4). Identify the cause. The map M for abnormality determination is stored in the storage unit 72 of the controller 70.

  The controller 70 performs a notification step. In the notification step, a notification for prompting setting adjustment or maintenance of at least one of the card machine 10, the drawing machine 30, and the pneumatic spinning machine 50 is performed in accordance with the determination result determined in the abnormality determination. The notification is a notification urging setting adjustment or maintenance for eliminating the cause of the abnormality estimated in the abnormality determining step. The notification includes, for example, lighting or blinking of a notification lamp of at least one of the card machine 10, the drawing machine 30, and the air spinning machine 50 having the cause of the abnormality. In the notification step, a display urging the setting adjustment or maintenance of at least one of the card machine 10, the drawing machine 30, and the air spinning machine 50 is displayed on the display unit 90. The display unit 90 is, for example, a monitor of a portable terminal such as a tablet. The display unit 90 can communicate with the controller 70.

  In the controller 70, a first threshold value, which is a management limit value of the fluctuation of the third quality data, and a second threshold value smaller (severe) than the first threshold value are set. When the operator changes the setting data of the card machine 10 and the third quality data is larger than the first threshold value, the controller 70 enables the re-change of the setting data of the card machine 10 to be input. Is smaller than the first threshold value and larger than the second threshold value, the setting data of the card machine 10 is returned to the immediately preceding setting data. If the third quality data is equal to or smaller than the second threshold value, The setting data of the card machine 10 is returned to the setting data before the change (details will be described later).

  In the fiber processing system 1, two card machines 10, one drawing machine, and two air spinning machines 50 form one route group U having the same fiber processing route. If the yarn generated by a certain air spinning machine 50 is defective, the abnormality determination step is performed in the route group U to which the air spinning machine 50 belongs. In this case, the abnormality determination of another pneumatic spinning machine 50 may be omitted.

  Specifically, when the yarn generated by a certain air spinning machine 50 is defective, the first to third quality data in the route group U to which the air spinning machine 50 belongs and the setting data of the card machine 10 and the drawing machine 30 are set. Based on this, it is determined at least one of the yarn raw material, the air spinning machine 50, the drawing machine 30 and the card machine 10 in the route group U to which the air spinning machine 50 belongs, in which an abnormality has occurred. That is, when the yarn is defective, the raw material of the yarn, the air spinning machine 50 that has produced the yarn, the drawing machine 30 that draws the fiber bundle supplied to the air spinning machine 50, and the drawing machine It is determined at least one of the card machines 10 that has generated the fiber bundle supplied to 30 has an abnormality. Information on the route group U (correspondence relationship between the card machine 10, the drawing machine 30, and the air spinning machine 50) having the same fiber processing route is predetermined and stored in the storage unit 72 (see FIG. 3) of the controller 70. ing. The controller 70 may make the determination based on the setting data of the pneumatic spinning machine 50 as well.

  As shown in FIG. 3, a fiber processing program P is stored in the storage unit 72 of the controller 70. The storage unit 72 is a non-temporary computer-readable storage medium that stores the fiber processing program P. The controller 70 implements the fiber processing method by reading and executing the fiber processing program P on a processor. The fiber processing program P includes an abnormality determination module P1. The abnormality determination module P1 causes the controller 70 to execute the abnormality determination process related to the above-described abnormality determination process. The fiber processing program P may be provided after being fixedly recorded on a tangible recording medium such as a CD-ROM, a DVD-ROM, and a semiconductor memory. Alternatively, the fiber processing program P may be provided as a data signal via a communication network.

  Next, an example of a fiber processing method performed by the fiber processing system 1 will be described.

  In the fiber treatment method, as described above, the fiber bundle is generated from the raw material using the card machine 10 (carding step). The produced fiber bundle is drawn using the drawing machine 30 (drawing step). The drawn fiber bundle is spun using the air spinning machine 50 to produce a yarn (air spinning step). First quality data is obtained by the first quality data obtaining unit 11 (first obtaining step). The second quality data is acquired by the second quality data acquisition unit 31 (second acquisition step). The third quality data is acquired by the third quality data acquisition unit 51 (third acquisition step).

  In the fiber processing method, when the yarn generated by the air spinning machine 50 is defective, the setting data of the card machine 10, the setting data of the drawing machine 30, and the first quality data are referred to the map M shown in FIG. Based on the second quality data and the third quality data, an abnormal part in a processing route through which the defective yarn passes is determined (an abnormality determining step). In the abnormality determination step, the cause of the abnormality may be further estimated.

  The setting data of the card machine 10 is the setting data of the card machine 10 in the processing route through which the defective thread has passed. The setting data of the drawing machine 30 is the setting data of the drawing machine 30 in the processing route through which the defective yarn has passed. The first quality data is the quality data of the fiber bundle generated by the card machine 10 in the processing route through which the defective yarn has passed. The second quality data is quality data of the fiber bundle drawn by the drawing machine 30 in the processing route through which the defective yarn has passed. The third quality data is quality data of the defective yarn.

  In the map M, the setting data of the card machine 10 includes the generation speed of the fiber bundle and the removal amount of the NEP from the fiber bundle. The first quality data includes the number of NEPs included in the fiber bundle detected by the sensor of the card machine 10 and a variation in the thickness of the fiber bundle. The setting data of the drawing machine 30 includes the drawing speed of the fiber bundle and whether or not the setting of the auto-leveler is changed. In addition to or instead of the setting change of the auto-leveler, the gauge of the draft roller (the distance between the plurality of draft rollers in the draft direction) and / or the draft ratio (the plurality of drafts in the draft direction) Roller ratio). The second quality data includes a change in the thickness of the fiber bundle detected by the sensor of the drawing machine 30. The third quality data includes the number of small defects and variation in thickness of the yarn detected by the sensor of the air spinning machine 50.

  “Increase” and “change” of the map M mean a change equal to or greater than a predetermined value. “−” In the map M means that there is no change (no change with respect to a predetermined value). The “change to a setting that reduces the NEP removal amount” in the setting of the card machine 10 means that the distance between the main cylinder and the top flat of the card machine 10 is increased, the distance between the main cylinder and the stationary flat is increased, and At least one of adjusting the angle of the moat knife (reducing the size of the suction opening).

  The wire (teeth) of the card machine 10 is a sharp pyramid-shaped portion provided with a large number of tips on the outer peripheral surface of the main cylinder. The doffer section of the card machine 10 is a device for guiding a fiber bundle from a main cylinder to a draft device or a can. The state where the draft device of the drawing machine 30 is inappropriate is a state where the draft ratio and / or the gauge of the draft roller are inappropriate. The abnormality in the entire draft section of the air spinning machine 50 means that there is an abnormality (e.g., a draft roller gauge and / or fly waste accumulation) somewhere in the entire draft section except the front top roller.

  As shown in the drawing, in the abnormality determination step, the number of neps included in the fiber bundle detected by the sensor of the card machine 10 increases, and the number and the thickness of the small defects of the yarn detected by the sensor of the air spinning machine 50. When there is no fluctuation in other data, it is determined that the abnormal part is a raw material, and it is estimated that the cause of the abnormality is a deterioration in raw material quality. Specifically, for example, even if there is no abnormality in the raw material of the fiber bundle before being processed by the card machine 10, even if there is no abnormality in the raw material of the fiber bundle, the abnormality in the management of the temperature and / or the humidity of the fiber bundle may occur. is there. Alternatively, the number of neps included in the fiber bundle detected by the sensor of the card machine 10 increases, and the number of small defects and the thickness of the yarn detected by the sensor of the air spinning machine 50 fluctuate.

The operator changes the setting data of the card machine 10 through the card machine 10 or the operation input unit of the controller 70 (second step).

  If the third quality data is larger than the first threshold, the process returns to the second step. If the third quality data is equal to or smaller than the first threshold and equal to or larger than the second threshold, the controller 70 returns the setting data of the card machine 10 to the setting data before the immediately preceding second step.
