Definitions

  • the present invention principally relates to a yarn winding machine having a function to inspect a joint formed by a yarn joining device.
  • Yarn winding machines equipped with a yarn supplying section, a winding section, and a yarn joining device are known in the art.
  • the winding section winds a yarn by rotating a package.
  • the yarn joining device joins the yarn from the yarn supplying section and the yarn from the winding section.
  • Yarn winding machines equipped with such a yarn joining device are disclosed, for example, in Japanese Patent Application Laid-open No. 2013-67892 (Patent Document 1), Japanese Patent Application Laid-open No. 2013-230908 (Patent Document 2), and Japanese Patent Application Laid-open No. H2-215662 (Patent Document 3).
  • the yarn winding machine disclosed in Patent Document 1 includes plural spinning units. All the spinning units are driven by a common driving source, and therefore, a rotation speed of a winding drum that rotates a package is the same in all the spinning units.
  • Each spinning unit includes a joint monitor that monitors a thickness of a joint formed by the yarn joining device. Each spinning unit cuts the yarn and joins the yarn again if the joint monitor determines that the joint is not normal.
  • the yarn winding machine disclosed in Patent Document 2 has a yarn monitoring device arranged upstream of a yarn joining device.
  • the yarn monitoring device is an optical-type sensor or the like, and monitors the quality of the yarn by detecting the thickness of the yarn passing through a yarn passage.
  • the yarn monitoring device includes a blowing member that blows compressed air in the yarn passage. By this action, yarn waste adhering to the yarn passage is blown off, and thereby, the monitoring accuracy of the yarn monitoring device can be maintained.
  • a method of inspection of a yarn joining device is disclosed in Patent Document 3.
  • the yarn winding machine has a mode in which an inspection of the yarn joining device is performed.
  • the package is rotated at a lower speed after yarn joining has been performed, and a predetermined tension is applied on the yarn supplied from a yarn supplying section to detect presence of a yarn breakage. If a yarn breakage occurs, the yarn winding machine notifies an operator that the yarn joining is incomplete. If yarn breakage does not occur, the yarn winding machine cuts the yarn and performs the yarn joining again.
  • Patent Document 3 teaches control for rotating the package at a lower speed after the yarn joining has been completed when in the mode in which the inspection of the yarn joining device is performed. However, there is no mention of whether this control is performed even during normal winding. In the mode in which the inspection of the yarn joining device is performed, because the yarn is cut once after the package is rotated at lower speed following the yarn joining, the rotation speed of the package is not increased.
  • EP 2 361 867 A2 discloses features falling under the preamble of claim 1.
  • a yarn winding machine according to an aspect of the present invention has the features of claim 1.
  • a yarn winding method according to another aspect of the present invention has the features of claim 11.
  • upstream and downstream refer to upstream and downstream in a traveling direction of a fiber bundle and a spun yarn during spinning.
  • the spinning machine includes plural spinning units 2 arranged side by side and a not shown main control device that performs centralized management of the spinning units 2.
  • an air-jet spinning device (yarn supplying section) 9 spins a fiber bundle 8 conveyed from a drafting device 7 to form a spun yarn 10, and a winding section 26 winds the spun yarn 10 to form a package 50.
  • each spinning unit 2 includes, sequentially from upstream to downstream, the drafting device 7, the air-jet spinning device 9, a yarn pooling device 22, a yarn joining device 23, a yarn monitoring device (detecting section) 25, and the winding section 26. All the parts of the spinning unit 2 are controlled by a unit controller 90 arranged in the spinning unit 2. All the parts of the spinning unit 2 can instead be controlled by the main control device.
  • the drafting device 7 includes, sequentially from the upstream, four draft rollers, namely, a back roller 16, a third roller 17, a middle roller 19 with a rubber apron belt 18, and a front roller 20. Each of the draft rollers is driven to rotate at a predetermined rotation speed.
  • the drafting device 7 includes opposing rollers arranged respectively facing the draft rollers.
  • the drafting device 7 transports a sliver 15 supplied from a sliver case (not shown) via a sliver guide (not shown) by nipping the sliver 15 between the draft rollers and the opposing rollers, thus forming a fiber bundle 8 by stretching (drafting) the sliver 15 until a predetermined fiber amount (or thickness) is obtained.
  • the air-jet spinning device 9 is arranged immediately downstream of the front roller 20.
  • the air-jet spinning device 9 forms the spun yarn 10 by twisting the fiber bundle 8 supplied from the drafting device 7.
  • an air-jet spinning device that twists the fiber bundle 8 by using a swirling airflow has been employed.
  • a first guide 61 (see FIG. 2 ) that guides the spun yarn 10 is arranged downstream of the air-jet spinning device 9.
  • the first guide 61 guides the spun yarn 10 to the yarn pooling device 22.
  • the first guide 61 is movable so that it can pull the spun yarn 10 to the yarn pooling device 22 for performing yarn joining or the like.
  • the yarn pooling device 22 is arranged downstream of the first guide 61.
  • the yarn pooling device 22 includes a yarn pooling roller 41, an electric motor 42 that drives the yarn pooling roller 41 to rotate, and a yarn hooking member 43.
  • the spun yarn 10 is temporarily pooled by being wound around the outer circumferential surface of the yarn pooling roller 41.
  • the yarn hooking member 43 is mounted on a downstream end portion of the yarn pooling roller 41.
  • the yarn hooking member 43 is supported in a rotatable manner relatively to the yarn pooling roller 41.
  • a permanent magnet is attached to any one of the yarn hooking member 43 and the yarn pooling roller 41, and a magnetic hysteresis member is attached to the other of the yarn hooking member 43 and the yarn pooling roller 41. These magnetic means generate a torque against a relative rotation of the yarn hooking member 43 with respect to the yarn pooling roller 41.
  • the yarn hooking member 43 is rotated relatively to the yarn pooling roller 41 so that the spun yarn 10 wound around the yarn pooling roller 41 can be unwound.
  • the yarn pooling roller 41 and the yarn hooking member 43 are integrally rotated so that the spun yarn 10 is wound around the yarn pooling roller 41.
  • the yarn pooling device 22 operates such that the spun yarn 10 is unwound when the yarn tension on the downstream is increased, and the spun yarn 10 is prevented from being unwound when the yarn tension is decreased (when the spun yarn 10 is about to have a slack). With this operation, the yarn pooling device 22 can remove the slack of the spun yarn 10 and apply an appropriate tension on the spun yarn 10. Furthermore, because the yarn hooking member 43 operates to absorb a variation of the tension applied on the spun yarn 10 between the yarn pooling device 22 and the winding section 26, the variation of the tension is prevented from affecting the spun yarn 10 between the air-jet spinning device 9 and the yarn pooling device 22.
  • a second guide 62 that regulates the spun yarn 10 unwound from the yarn pooling roller 41 is arranged downstream of the yarn pooling roller 41.
  • the yarn joining device 23 is arranged downstream of the second guide 62.
  • the yarn joining device 23 joins the spun yarn 10 from the air-jet spinning device 9 (first yarn) and the spun yarn 10 from the package 50 (second yarn) when the spun yarn 10 is disconnected between the air-jet spinning device 9 and the package 50 due to any reason.
  • the yarn joining device 23 is a splicer device that twists and joins the yarn ends by the action of a swirling air current generated by compressed air.
  • the yarn joining device 23, however, is not limited to the splicer device, and can be, for example, a mechanical knotter and the like.
  • the spinning unit 2 includes a first catching and guiding device 27 and a second catching and guiding device (catching and guiding device) 28 that guide the spun yarn 10 to the yarn joining device 23.
  • the first catching and guiding device 27 includes a base portion that is pivotably supported, and is able to pivot in a vertical direction around the base portion as a center.
  • the first catching and guiding device 27 is hollow, connected to a not shown blower, and can generate a suction airflow.
  • the first catching and guiding device 27 catches an end of the first yarn by pivoting downward (see FIG. 7 ). After catching the first yarn, the first catching and guiding device 27 guides the first yarn to the yarn joining device 23 by pivoting upward.
  • the second catching and guiding device 28 includes a base portion that is pivotably supported, and is able to pivot in the vertical direction around the base portion as a center.
  • the second catching and guiding device 28 is also hollow, connected to a not shown blower, and can generate a suction airflow.
  • the second catching and guiding device 28 catches an end of the second yarn by pivoting upward (see FIG. 7 ). After catching the second yarn, the second catching and guiding device 28 guides the second yarn to the yarn joining device 23 by pivoting downward.
  • the yarn joining device 23 By driving the yarn joining device 23 in a state in which the first yarn and the second yarn are guided in the yarn joining device 23, the first yarn and the second yarn are joined to bring the spun yarn 10 in a continuous state between the air-jet spinning device 9 and the package 50. Due to this, the winding of the spun yarn 10 on the package 50 can be resumed.
  • the yarn joining device 23 shown in FIG. 3 includes a yarn joining nozzle 71, a pair of yarn pulling levers (yarn pulling sections) 72, a pair of clamps (holding sections) 73, a pair of yarn holding-down levers 74, a pair of untwisting pipes 75, and a pair of cutters 76.
  • a yarn joining hole 70 is formed in the yarn joining nozzle 71.
  • a not shown blowoff port is formed inside the yarn joining hole 70. The swirling airflow is generated inside the yarn joining hole 70 when compressed air is blown from the blowoff port.
  • Each of the pairs of the yarn pulling levers 72, the clamps 73, and the yarn holding-down levers 74 are arranged sandwiching the yarn joining nozzle 71.
  • the yarn pulling levers 72 pull the first yarn and the second yarn guided to the yarn joining device 23 toward the yarn joining nozzle 71.
  • the clamps 73 hold the first yarn and the second yarn that have been guided to the yarn joining nozzle 71 at predetermined places.
  • the yarn holding-down levers 74 hold down and position the first yarn and the second yarn during yarn joining at the yarn joining nozzle 71.
  • One untwisting pipe 75 is arranged corresponding to the first yarn and another untwisting pipe 75 is arranged corresponding to the second yarn. Compressed air is blown inside each untwisting pipe 75 from a not shown compressed air passage.
  • the first yarn and the second yarn guided to the yarn joining device 23 are pulled toward the respective untwisting pipes 75 by the respective yarn pulling levers 72 and held by the clamps 73.
  • the first yarn and the second yarn are cut to a predetermined length by the respective cutters 76.
  • the fibers at the ends of the first yarn and the second yarn are untwisted inside the respective untwisting pipes 75 by the action of an airflow.
  • the first yarn and the second yarn are pulled out from the respective untwisting pipes 75 and positioned overlapping each other inside the yarn joining hole 70 of the yarn joining nozzle 71 by the holding down action of the yarn holding-down levers 74.
  • a swirling flow of compressed air is generated by blowing the compressed air into the yarn joining hole 70, and thereby the first yarn and the second yarn are twisted together to form a joint.
  • the hold on the first yarn and the second yarn by the clamps 73 is released, and the operations of the yarn pulling levers 72 and the yarn holding-down levers 74 are released.
  • the portion where the joint is formed cannot be confirmed visually or at least will be difficult to confirm visually because the yarn joining is performed by the action of the swirling flow of the compressed air.
  • the term "joint" shall be used to refer to the yarn in the portion where the yarn joining has been performed.
  • the yarn monitoring device 25 is arranged downstream of the yarn joining device 23.
  • the yarn monitoring device 25 monitors a thickness of the traveling spun yarn 10 with a capacitance type sensor.
  • the yarn monitoring device 25 includes a housing 80, a first air blowing member (yarn removing section, air blowing section) 82, a second air blowing member (yarn removing section, air blowing section) 83, and a cutter 85.
  • the cutter 85 can be arranged independently of the yarn monitoring device 25.
  • a slit-like concave portion 81 is formed in the housing 80.
  • the spun yarn 10 travels inside the concave portion 81.
  • the concave portion 81 is formed like a linear groove with one side open.
  • the inside of the concave portion 81 forms a detection area for detecting the spun yarn 10.
  • the cutter 85 is arranged further upstream than the detection area in a yarn traveling direction.
  • the first air blowing member 82 includes a first air blowoff port 82a formed on an inner wall on the interior side of the concave portion 81. By blowing air through the first air blowoff port 82a, the first air blowing member 82 generates airflow along the side walls of the groove-like concave portion 81 and blows air to the cutter 85, and the like.
  • a slit-like second blowoff port 83a is formed in the second air blowing member 83.
  • the second air blowing member 83 blows air inside the concave portion 81 in a direction indicated by the arrow in FIG. 4 , that is, obliquely relative to a width direction of the groove-like concave portion 81 and also obliquely relative to the yarn traveling direction.
  • the air blown from the second blowoff port 83a of the second air blowing member 83 is blown into the concave portion 81 from the open side of the concave portion 81 and upstream side of yarn traveling direction, and hits the side wall on one side of the concave portion 81 slantingly.
  • a helical airflow is thereby generated inside the concave portion 81.
  • the yarn monitoring device 25 transmits the quality information of the spun yarn 10 obtained as a result of monitoring to a unit controller (determining section, controller) 90.
  • the unit controller 90 can thereby determine whether the joint formed by the yarn joining device 23 is normal and whether any defect (a place where the thickness of the spun yarn 10 or the like is abnormal) is present in the spun yarn 10 that is being wound. If abnormality in the joint or a yarn defect or the like is present, the unit controller 90 drives the cutter 85 (yarn cutting device) arranged near the yarn monitoring device 25 to cut the spun yarn 10.
  • the sensor with which the yarn monitoring device 25 monitors the thickness of the spun yarn 10 is not limited to a capacitance type sensor, and can, for example, be an optical transmission type sensor. Moreover, a foreign matter included in the spun yarn 10 can be monitored as the yarn defect.
  • the cutter 85 can be omitted, and the spun yarn 10 can be cut by suspending the formation of the spun yarn 10 by the air-jet spinning device 9.
  • the winding section 26 is arranged downstream of the yarn pooling device 22.
  • the winding section 26 includes a cradle arm 52, a winding drum 53, and a winding-drum driving motor (rotation driving unit) 54.
  • a direction of a yarn path from the yarn pooling device 22 to the winding section 26 is bent and guided by a downstream guide 63.
  • a restraining guide (restraining section) 64 is arranged near the downstream guide 63.
  • the cradle arm 52 rotatably supports a winding tube 51 on which the spun yarn 10 is to be wound.
  • the cradle arm 52 is pivotable around a base portion as a center of pivoting. With this configuration, even when a diameter of the package 50 increases with the winding of the spun yarn 10 around the winding tube 51, the winding of the spun yarn 10 can be continued properly.
  • the winding drum 53 rotates while being in contact with an outer circumferential surface of the winding tube 51 or the package 50 by a driving force transmitted from the winding-drum driving motor 54.
  • a not shown traverse groove is formed on an outer circumferential surface of the winding drum 53 and the spun yarn 10 can be traversed to a predetermined width using this traverse groove.
  • the winding section 26 can form the package 50 by winding the spun yarn 10 around the winding tube 51 while traversing the spun yarn 10.
  • the winding drum 53 of every spinning unit 2 can be rotated at a different speed.
  • a process procedure performed by the spinning unit 2 when a yarn breakage or yarn cutting occurs is explained below with reference to FIGS. 5 to 10 .
  • the process procedure shown in the flowchart in FIG. 5 is merely an example; the sequence of the process procedure can be changed, and two processes can even be performed simultaneously.
  • the spinning unit 2 stops the rotation of the package 50 using a package brake or the like (Step S102), and also stops the drafting by the drafting device 7 and the spinning by the air-jet spinning device 9.
  • the first guide 61 moves to a position that is located away from the yarn pooling device 22.
  • Step S103 an operation of catching the disconnected yarn ends and guiding the yarn ends to the yarn joining device 23 is performed (Step S103). Specifically, as shown in FIG. 7 , the second catching and guiding device 28 pivots upward and catches the second yarn. Thereafter, the second catching and guiding device 28 pivots downward while the winding section 26 rotates the package 50 backward. By these actions, the second yarn is guided to a position where the yarn joining can be performed by the yarn joining device 23.
  • the first catching and guiding device 27 pivots downward and moves to a position where the first yarn can be caught.
  • the drafting by the drafting device 7 and the spinning by the air-jet spinning device 9 are then resumed, and thereby, the first yarn is sucked and caught by the first catching and guiding device 27.
  • the first catching and guiding device 27 then pivots upward, with the first yarn sucked and held. By this action, the first yarn is guided to a position where the yarn joining can be performed by the yarn joining device 23.
  • the first guide 61 then moves so as to approach the yarn pooling device 22. By this action, the spun yarn 10 is pulled to the yarn hooking member 43 of the yarn pooling device 22.
  • the yarn joining device 23 then performs a yarn joining operation to form a joint between the first yarn and the second yarn (Step S104). Thereafter, the winding section 26 rotates the package 50 and winds the spun yarn 10. While rotating the package 50, as shown in FIG. 6A , the winding section 26 accelerates the package 50 by a first acceleration (Step S105). The first acceleration is lower than both a second acceleration shown in FIG. 6A and the acceleration in a conventional case shown in FIG. 6B .
  • the spinning unit 2 performs a yarn removal process (Step S106).
  • the yarn removal process is a process of applying a force on the spun yarn 10 so as to remove the spun yarn 10 from the detection area of the yarn monitoring device 25.
  • the yarn removal process is performed by blowing air by at least one of the first air blowing member 82 and the second air blowing member 83.
  • the spun yarn 10 Upon successful yarn joining, the spun yarn 10 is continuous and has a tension applied thereon, as shown in FIG. 8 , and therefore is not affected by the yarn removal process. In contrast, when the yarn joining fails, as shown in FIG. 9 , the second yarn comes off from the yarn monitoring device 25 in the yarn removal process. The second yarn that has come off from the yarn monitoring device 25 is guided to the restraining guide 64. The movement of the second yarn is thereby restrained, enabling the position of the end of the second yarn to be easily specified.
  • Failed yarn joining can be determined at an early timing by performing the yarn removal process early.
  • the yarn removal process is performed, for example, after the looseness of the spun yarn 10 that occurs when the spun yarn 10 is released is lost following the joint formation process performed by the yarn joining device 23.
  • the yarn removal process can be performed after the clamps 73 release the spun yarn 10 and before the yarn pulling levers 72 release the first yarn and the second yarn.
  • the unit controller 90 determines whether the joint formed in the spun yarn 10 is normal (Step S107).
  • the unit controller 90 determines that the joint is normal when the joint of the spun yarn 10 detected by the yarn monitoring device 25 satisfies a predetermined condition (thickness or the like).
  • the unit controller 90 can be configured to determine the joint to be a normal joint when the spun yarn 10 is detected continuously for a predetermined time period.
  • the unit controller 90 determines that yarn joining has failed (Step S108).
  • the unit controller 90 determines whether the yarn joining has failed successively for a predetermined number of times (Step S109). If the yarn joining has failed successively for the predetermined number of times, the spinning unit 2 notifies the failure to an operator by lighting a not shown lamp or by sounding an alarm or the like (Step S110).
  • the winding section 26 stops the rotation of the package 50 (Step S102).
  • the package 50 is rotated at a lower first acceleration as explained above, a rotation speed of the package 50 at the time of determination of a failed yarn joining is low. Consequently, the package 50 can be stopped before the end of the second yarn is wound onto the package 50.
  • the second catching and guiding device 28 can suck and catch the end of the second yarn under a state in which the yarn end is located away from the package 50. Consequently, the probability of occurrence of an error when catching the yarn end can be reduced.
  • the spinning unit 2 performs the processes from Step S102 onward as explained above.
  • the winding section 26 increases the rotation speed of the package 50 by the second acceleration (see Step S111 and FIG. 6A ).
  • the second acceleration is higher than the first acceleration and the conventional acceleration.
  • the winding section 26 determines whether the rotation speed of the package 50 has reached a target speed (Step S112), and ends the acceleration of the package 50 (Step S113) at a time point when the package 50 reaches the target speed.
  • the target speed can be reached in a shorter time.
  • the package 50 can be stopped while it is rotating at a lower speed if failed yarn joining can be detected early, and thereby the end of the second yarn can be restrained from getting wound onto the package 50.
  • the yarn removal process is performed after the joint formation but before the rotation of the package 50. Because the spun yarn 10 is loose after the joint formation, even if the yarn joining is successful, the spun yarn 10 can potentially be removed from the yarn monitoring device 25 by the yarn removal process. Therefore, tension needs to be applied on the spun yarn 10 with a tension applying device or the like.
  • the yarn monitoring device 25 fails to detect the spun yarn 10 because of the yarn removal process, this is determined as failed yarn joining. In this case, because unnecessary rotation of the package 50 is not performed, the yarn joining can be performed once again and at an early timing.
  • the spinning machine includes the air-jet spinning device 9, the winding section 26, the yarn joining device 23, the yarn monitoring device 25, and the unit controller 90.
  • the air-jet spinning device 9 supplies the spun yarn 10.
  • the winding section 26 includes the winding drum driving motor 54 that rotates the package 50, and winds the spun yarn 10 supplied by the air-jet spinning device 9 to form the package 50.
  • the yarn joining device 23 joins the first yarn from the air-jet spinning device 9 and the second yarn from the winding section 26.
  • the yarn monitoring device 25 detects the joint that is the portion where the yarn joining is performed by the yarn joining device 23.
  • the unit controller 90 determines whether the joint is normal based on the detection result of the yarn monitoring device 25.
  • the winding section 26 performs winding of the package 50 by increasing the acceleration of the rotation speed of the package 50 after the unit controller 90 determines that the joint is normal.
  • the acceleration of the package 50 is increased to accelerate the rotation speed of the package 50 to the target speed after it is determined that the joint is normal.
  • the rotation speed of the package 50 is restrained until the determination is performed.
  • the average acceleration in the time period between the time point when the rotation of the package 50 is started by the winding section 26 and the time point when it is determined whether the joint is normal by the unit controller 90 is regarded as the first acceleration and the average acceleration in the time period between the time point when the joint is determined to be normal by the unit controller 90 and the time point when the rotation speed of the package 50 reaches the target speed is regarded as the second acceleration.
  • the winding section 26 changes the rotation speed of the package 50 such that the second acceleration is higher than the first acceleration.
  • the winding section 26 stops the winding of the package 50 before the yarn end is wound onto the package 50.
  • the yarn end of the package 50 can be reliably caught.
  • the spinning machine according to the present embodiment includes the first air blowing member 82 and the second air blowing member 83 that apply a force on the yarn in the direction in which the yarn is removed from the yarn monitoring device 25 after the yarn joining is performed by the yarn joining device 23.
  • the yarn On receiving the force from the first air blowing member 82 or the like, the yarn is removed from the yarn monitoring device 25 in the event of a failed yarn joining but not removed from the yarn monitoring device 25 in the event of a successful yarn joining. Hence, whether the yarn joining is successful can be determined at an early timing by performing the yarn removal process.
  • the first air blowing member 82 and the second air blowing member 83 equipped in the yarn monitoring device 25 are explained as the yarn removing members.
  • the air blowing members can, however, be arranged in other part. Instead of a fluid, such as air or the like, a solid body can be caused to come into contact with the spun yarn 10, if the structure is such that the solid body applies just enough force on the spun yarn 10 so as not to affect the yarn quality when used in the event of a successful yarn joining.
  • the unit controller 90 determines that the spun yarn 10 is not present. This determination criterion can be changed depending on whether it is immediately after the yarn joining or it is during normal winding. The determination can be performed early by reducing the predetermined duration immediately after the yarn joining. Consequently, in the event of a failed yarn joining, the rotation speed of the package 50 can be set to a still lower value.
  • separate devices can be arranged for determining whether the joint is normal and for monitoring the quality of the traveling spun yarn 10.
  • the first acceleration and the second acceleration are constant.
  • one or both of the first acceleration and the second acceleration can be made variable.
  • the average acceleration between the time point when the yarn joining is completed and the time point when the joint is determined to be normal is lower than the average acceleration between the time point when the joint is determined to be normal and the time point when the target speed is reached.
  • the unit controller 90 of the spinning unit 2 has been given the function to determine whether the joint is normal based on the detection result of the yarn monitoring device 25.
  • this function can be given to a controller that controls the yarn monitoring device 25 or to a main control device.
  • the present invention is adapted to a spinning machine in which the package 50 is formed at a position that is above the spinning unit 2.
  • the present invention can also be adapted to a spinning machine in which the package 50 is formed at a position that is below the spinning unit 2 (for example, as in Japanese Patent Application Laid-open No. 2013-67892 ).
  • the present invention can also be adapted to a yarn winding machine, such as an automatic winder or the like. In this case, a structure that unwinds the yarn from a yarn supplying bobbin will correspond to the yarn supplying member.
  • a yarn winding machine includes a yarn supplying section that supplies a yarn; a winding section that winds the yarn supplied by the yarn supplying section to form a package and includes a rotation driving unit that rotates the package; a yarn joining device that joins the yarn from the yarn supplying section and the yarn from the winding section; a detecting section that detects a joint that is a portion where yarn joining is performed by the yarn joining device; and a determining section that determines whether the joint is normal based on a detection result obtained by the detecting section, wherein the winding section performs winding of the package by increasing acceleration of a rotation speed of the package after the determining section determines that the joint is normal.
  • the acceleration of the package is increased to accelerate the rotation speed of the package to the target speed after it is determined that the joint is normal.
  • the rotation speed of the package is restrained until the determination of the joint is completed.
  • an average acceleration in a first time period is regarded as a first acceleration
  • an average acceleration in a second time period is regarded as a second acceleration
  • the winding section changes the rotation speed of the package such that the second acceleration is higher than the first acceleration
  • the winding section stops the winding of the package when the determining section determines that the joint has not been formed or the joint is abnormal.
  • the winding section stops the winding of the package before a yarn end is wound onto the package when the determining section determines that the joint has not been formed or the joint is abnormal.
  • the above yarn winding machine further includes a yarn removing section that performs a yarn removal process in which a force is applied on the yarn in a direction in which the yarn is removed from the detecting section after the yarn joining is performed by the yarn joining device.
  • the yarn On receiving the force from the yarn removing section, the yarn is removed from the detecting section in the event of a failed yarn joining but not removed from the detecting section in the event of a successful yarn joining. Hence, whether the yarn joining is successful can be determined at an early timing by performing the yarn removal process.
  • the yarn removing section is an air blowing section that blows air in a yarn path of the yarn that is wound to form the package.
  • the yarn removing section performs the yarn removal process after looseness of the yarn that occurs when the yarn is released by the yarn joining device is lost following resumption of the winding of the package by the winding section.
  • the yarn joining device includes a holding section that holds the yarn being joined and a yarn pulling section that pulls the yarn that is held by the holding section, and the yarn removing section performs the yarn removal process after the holding section releases the yarn and before the yarn pulling section releases the yarn.
  • the above yarn winding machine further includes a restraining section that restrains movement of the yarn that has been subjected to the yarn removal process by the yarn removing section; and a catching and guiding device that catches the yarn from the package restrained by the restraining section and guides the yarn to the yarn joining device.
  • the catching and guiding device can catch the yarn more reliably.
  • the above yarn winding machine further includes a yarn pooling device that pools the yarn at a position between the yarn supplying section and the winding section.
  • the yarn winding machine includes the yarn pooling device, because whether the yarn joining has been successful can be determined at an early timing, a pooled amount of the yarn in the yarn pooling device in the time period in which the determining section performs the determination can be reduced. Hence, in the event of a failed yarn joining, an amount of the yarn that is discarded and the time required for discarding the waste yarn can be reduced.
  • the above yarn winding machine further includes a controller that controls at least the winding section, the yarn joining device, and the detecting section.
  • a yarn winding method includes joining a yarn from a yarn supplying section that supplies the yarn and a yarn from a winding section that winds the yarn supplied by the yarn supplying section to form a package; detecting a joint that is a portion where yarn joining is performed at the joining; determining whether the joint is normal based on a detection result obtained at the detecting; and winding the package by increasing acceleration of a rotation speed of the package after the joint is determined to be normal at the determining.
  • the acceleration of the package is increased to accelerate the rotation speed of the package to the target speed after it is determined that the joint is normal.
  • the rotation speed of the package is restrained until the determination of the joint is performed.
