Definitions

  • the present invention relates to a winding device and a yarn winding machine including the same.
  • Japanese Patent Application Laid-open No. 2011-37608 discloses a textile machine including a winding device adapted to wind a yarn around a bobbin held by a package holding section to form a package.
  • the winding device includes the package holding section adapted to rotatably support the bobbin or a package, a contact roller adapted to rotate the package while making contact with the package, and a switching mechanism (a drive mechanism) adapted to move a position of the package by swinging the package holding section with a swinging shaft as a center.
  • the switching mechanism is controlled to move the package holding section to a receded position located away from the contact roller. Accordingly, since a winding speed of the package is decelerated, the accumulation amount in the yarn accumulating device can be increased.
  • EP 2 570 375 A2 describes a yarn winding unit including a frame, and a cradle device including a cradle arm adapted to rotatably hold a package around which a spun yarn is wound, an air cylinder adapted to drive the cradle arm, and an electromagnetic valve of a male connector section adapted to control the air cylinder, the cradle device being a module provided detachably to the frame.
  • the package holding section is not moved away from the contact roller at a predetermined timing, since an appropriate accumulation amount would not be secured in the yarn accumulating device, a defective package may be produced. If the package holding section is not moved away from the contact roller by a predetermined distance, a defect may be generated on a surface of the package, for example, a scrambled package may be formed. Therefore, a stable operation of the switching mechanism is demanded.
  • the stable operation of the switching mechanism includes, for example, reliably operating the switching mechanism at the predetermined timing, and/or operating the switching mechanism such that the package holding section is reliably moved away from the contact roller by the predetermined distance.
  • An object of the present invention is to provide a winding device capable of stably operating the switching mechanism adapted to move the package holding section away from the contact roller, and a yarn winding machine including the same.
  • a winding device includes a package holding section adapted to rotatably hold a package around which a yarn is wound, a switching mechanism adapted to move the package holding section from a winding position, which is a position where the package holding section is located when the yarn is wound around the package, to a receded position, which is a position located away from the winding position, and a control section adapted to operate the switching mechanism after the switching mechanism has moved the package holding section from the receded position to the winding position.
  • the switching mechanism if the switching mechanism is not returned to an initial state after the switching mechanism has moved the package holding section from the receded position to the winding position, a defect may occur during a next operation. That is, the switching mechanism may not be reliably operated at a predetermined timing or the switching mechanism may not be operated to reliably recede the package holding section by a predetermined amount.
  • the control section after the switching mechanism has moved the package holding section, the control section returns the switching mechanism to the initial state by operating the switching mechanism. In such a manner, the switching mechanism can be reliably operated at the predetermined timing, and the package holding section can be reliably moved to the receded position. Consequently, the switching mechanism can be stably operated.
  • the receded position includes a first position and a second position that is located further away from the winding position than the first position.
  • the switching mechanism includes a first switching mechanism adapted to move the package holding section from the winding position to the first position and a second switching mechanism adapted to move the first switching mechanism to move the package holding section from the winding position to the second position.
  • the control section returns the first switching mechanism to the initial state by operating the first switching mechanism. That is, by operating the first switching mechanism, the position of the first switching mechanism is returned to an original position.
  • the second switching mechanism moves in conjunction with the movement of the first switching mechanism, by operating the first switching mechanism, the second switching mechanism can be returned to the initial state. In such a manner, the position of the first switching mechanism can be reliably returned to the original position.
  • the package holding section can be moved to the first position that is assumed at the time of designing. Consequently, the first switching mechanism can be reliably operated at the predetermined timing, and the package holding section can be reliably moved to the first position.
  • control section may return the second switching mechanism to the initial state before the first switching mechanism moves the package holding section from the winding position to the first position.
  • the package holding section can be reliably moved to the first position.
  • the second switching mechanism may include a single-acting cylinder adapted to move the package holding section from the winding position to the second position and an elastic member adapted to move the package holding section from the second position to the winding position.
  • the control section returns the first switching mechanism to the initial state by operating the first switching mechanism. That is, by operating the first switching mechanism, the position of the first switching mechanism can be returned to the original position.
  • the elastic member of the second switching mechanism is returned to the initial state.
  • the position of the first switching mechanism can be reliably returned to the original position.
  • the package holding section can be moved to the assumed first position. Consequently, the first switching mechanism can be reliably operated at the predetermined timing, and the package holding section can be reliably moved to the first position.
  • the second switching mechanism adapted to move the package holding section from the winding position to the second position can be configured at a low cost.
  • the winding device may further include a contact roller adapted to rotate in contact with the package when the package holding section is located at the winding position.
  • a yarn winding machine may include the above-described winding device, a yarn accumulating device arranged upstream of the winding device and adapted to accumulate the yarn supplied from a yarn supplying device, and a yarn joining device adapted to perform a yarn joining operation to join the yarn from the yarn accumulating device and the yarn from the winding device.
  • the control section may move the package holding section to the first position when adjusting an accumulation amount of the yarn in the yarn accumulating device, and may move the package holding section to the second position when performing the yarn joining operation by the yarn joining device.
  • the control section moves the package holding section from the winding position to the second position for the yarn joining operation by the yarn joining device.
  • the control section operates the first switching mechanism (performs an ON/OFF control) to return the second switching mechanism to the initial state.
  • the second switching mechanism is always in the initial state. Consequently, since the package holding section can be reliably moved to the first position at the predetermined timing, the accumulation amount of the yarn can be reliably adjusted. Furthermore, an occurrence of a defect such as damage, for example, on a surface of the package caused by the package holding section that has not moved an assumed distance can be reduced.
  • control section may return the second switching mechanism to the initial state after the yarn joining operation is performed by the yarn joining device and before the accumulation amount of the yarn in the yarn accumulating device is adjusted.
  • the accumulation amount of the yarn can be reliably adjusted and the defect such as damage on the surface of the package can be reduced.
  • control section may return the second switching mechanism to the initial state after an elapse of a predetermined period of time after the yarn joining operation is performed by the yarn joining device.
  • the first switching mechanism can be stably operated with a simple setting.
  • the yarn accumulating device may include a yarn accumulating roller adapted to temporarily accumulate the yarn by rotating while the yarn is being wound around an outer peripheral surface thereof.
  • the yarn winding machine may further include a traverse guide provided independently from a contact roller adapted to rotate in contact with the package, and adapted to traverse the yarn to be wound around the package.
  • a traverse guide provided independently from a contact roller adapted to rotate in contact with the package, and adapted to traverse the yarn to be wound around the package.
  • the yarn winding machine even when an amount of the yarn wound around the yarn accumulating roller decreases, by moving the package holding section from the winding position to the first position, the yarn is wound at a speed faster than a speed in which the yarn is unwound from the yarn accumulating roller, and thus the accumulation amount of the yarn in the yarn accumulating roller can be increased. Furthermore, even when the yarn breakage or the like occurs, since the bunch-winding is formed on the package by moving the package holding section from the winding position to the second position, the yarn end can be prevented from being entangled with the member in proximity to the package.
  • upstream and downstream respectively indicate upstream and downstream in a travelling direction of a spun yarn (yarn) 10 at the time of spinning.
  • a spinning machine (yarn winding machine) 1 includes a plurality of spinning units 2, a yarn joining cart 3, a blower box 4, and a motor box 5.
  • the plurality of spinning units 2 is arranged in a row, and each of the spinning units 2 is adapted to produce the spun yarn 10 and to wind the spun yarn 10 around a package 45.
  • the yarn joining cart 3 is adapted to perform a yarn joining operation in a spinning unit 2 where the spun yarn 10 has been disconnected.
  • the blower box 4 accommodates an air supply source adapted to generate suction flow and/or whirling flow in each section of the spinning unit 2, and the like.
  • the motor box 5 accommodates a motor adapted to supply power to each section of the spinning unit 2, and the like.
  • each spinning unit 2 includes a draft device 7, a pneumatic spinning device (yarn supplying device) 9, a yarn accumulating device 12, and a winding device 13 as main components in this order from upstream towards downstream.
  • the draft device 7 is provided in proximity to an upper end of a frame 6 provided with the spinning machine 1.
  • a fiber bundle 8 fed from the draft device 7 is spun by the pneumatic spinning device 9.
  • the spun yarn 10 produced by the pneumatic spinning device 9 is wound by the winding device 13 via a yarn accumulating roller 21, and thus the package 45 is formed.
  • a bobbin 48 with yarn layers of the spun yarn 10 wound therearound is referred to as the package 45.
  • the draft device 7 is adapted to produce the fiber bundle 8 by stretching a sliver 15.
  • the draft device 7 includes four pairs of rollers, which are a pair of back rollers 16, a pair of third rollers 17, a pair of middle rollers 19 equipped with apron belts 18, and a pair of front rollers 20. Bottom rollers of each pair of rollers 16, 17, 19, 20 are driven by power from the motor box 5 or power of an electric motor (not illustrated) arranged in each spinning unit 2. Each pair of rollers 16, 17, 19, and 20 is respectively driven at rotational speeds that are different from one another. Accordingly, the sliver 15 supplied from upstream is stretched and formed into the fiber bundle 8, and the fiber bundle 8 is fed to the pneumatic spinning device 9 located downstream.
  • the pneumatic spinning device 9 is adapted to twist the fiber bundle 8 by use of whirling airflow to produce the spun yarn 10.
  • the pneumatic spinning device 9 includes a fiber guiding section, a whirling airflow generating nozzle, and a hollow guide shaft body.
  • the fiber guiding section is adapted to guide the fiber bundle 8 fed from the draft device 7 to a spinning chamber formed inside the pneumatic spinning device 9.
  • the whirling airflow generating nozzle is arranged around a path of the fiber bundle 8 and is adapted to generate the whirling airflow in the spinning chamber. With the whirling airflow, a fiber end of the fiber bundle 8 inside the spinning chamber is inverted and whirled.
  • the hollow guide shaft body is adapted to guide the spun yarn 10 from the spinning chamber to outside the pneumatic spinning device 9.
  • the pneumatic spinning device 9 is controlled to be driven/stopped by a unit controller 30 (see FIG. 3 ).
  • the yarn accumulating device 12 is provided downstream of the pneumatic spinning device 9.
  • the yarn accumulating device 12 includes the yarn accumulating roller 21, a yarn hooking member 22, an upstream guide 23, an electric motor 25, a downstream guide 26, and an accumulation amount sensor 27.
  • the yarn hooking member 22 is adapted to guide the spun yarn 10 to an outer peripheral surface of the yarn accumulating roller 21 by rotating together with the yarn accumulating roller 21 with the spun yarn 10 hooked thereon.
  • the yarn hooking member 22 is supported in a relatively rotatable manner with respect to the yarn accumulating roller 21.
  • the yarn accumulating roller 21 is adapted to temporarily accumulate the spun yarn 10 by winding the spun yarn 10 around the outer peripheral surface thereof.
  • the yarn accumulating roller 21 is rotationally driven at a constant rotational speed by the electric motor 25 controlled by the unit controller 30. With this configuration, the spun yarn 10 that has been guided to the outer peripheral surface of the yarn accumulating roller 21 by the yarn hooking member 22 is tightly wound around the yarn accumulating roller 21 by the rotation of the yarn accumulating roller 21 and pulls a spun yarn 10 located upstream of the yarn accumulating device 12. Accordingly, the spun yarn 10 can be continuously drawn from the pneumatic spinning device 9.
  • the accumulation amount sensor 27 is adapted to detect in a non-contacting manner, an accumulation amount of the spun yarn 10 wound around the yarn accumulating roller 21 and to transmit a detection signal to the unit controller 30.
  • the upstream guide 23 is arranged slightly upstream of the yarn accumulating roller 21.
  • the upstream guide 23 is adapted to appropriately guide the spun yarn 10 to the outer peripheral surface of the yarn accumulating roller 21.
  • the upstream guide 23 prevents twists of the spun yarn 10 that propagate from the pneumatic spinning device 9 from propagating to downstream of the upstream guide 23.
  • a yarn clearer 52 is provided on a front surface side of the frame 6 of the spinning machine 1 (a side of a worker passage) and between the pneumatic spinning device 9 and the yarn accumulating device 12.
  • the yarn clearer 52 is adapted to monitor a thickness of the travelling spun yarn 10 and/or a presence and an absence of a foreign substance in the spun yarn 10.
  • the yarn clearer 52 transmits a yarn defect detection signal to the unit controller 30 when detecting a yarn defect of the spun yarn 10.
  • the unit controller 30 When receiving the yarn defect detection signal, the unit controller 30 immediately stops injection of compressed air from the whirling airflow generating nozzle of the pneumatic spinning device 9. Accordingly, the whirling airflow is stopped and thereby twisting the fiber bundle 8 is stopped, and introduction of the fiber bundle 8 into the pneumatic spinning device 9 is also stopped. Then, a continuous state of fibers is disconnected in the pneumatic spinning device 9, and the spun yarn 10 is disconnected. Subsequently, the unit controller 30 further stops the draft device 7 and the like.
  • the unit controller 30 transmits a control signal to the yarn joining cart 3 to cause the yarn joining cart 3 to travel to the relevant spinning unit 2. Then, the unit controller 30 drives the pneumatic spinning device 9 and the like again, causes the yarn joining cart 3 to perform the yarn joining operation, and restarts winding in the relevant spinning unit 2. At this time, after the pneumatic spinning device 9 has restarted spinning and before the winding is restarted, the yarn accumulating device 12 eliminates slackening of the spun yarn 10 by accumulating the spun yarn 10, which is continuously fed from the pneumatic spinning machine 9, around the yarn accumulating roller 21.
  • the yarn joining cart 3 includes a splicer (a yarn joining device) 43, a suction pipe 44, and a suction mouth 46.

  • the suction mouth 46 is adapted to suck and catch a yarn end (a lower yarn) from the package 45 supported by the winding device 13 and to guide the caught yarn end to the splicer 43.
  • the winding device 13 includes a package holding section 71, a first switching mechanism
  • the winding device 13 moves the package holding section 71 to a first position and a second position by operating the first switching mechanism 60 and the second switching mechanism 80. Each of the first position and the second position is set in advance.

  • a portion in which the various types of control processing are performed in the unit controller 30 may be formed as hardware.
  • the unit controller 30 controls the first switching mechanism 60 and the second switching mechanism 80 to move the package holding section 71 (the package 45) to any one of the winding position, the first position, and the second position at a predetermined timing.
  • the unit controller 30 controls the first switching mechanism 60 or the second switching mechanism 80 to move the package holding section 71 away from the winding position at the predetermined timing.
  • a control performed to move the package holding section 71 away from the winding position by operating the first switching mechanism 60 or the second switching mechanism 80 will be referred to as a "move-away control".
  • the move-away control in the present embodiment includes a "lift-up control” to move the package holding section 71 from the winding position to the first position, and a “retreat control” to move the package holding section 71 from the winding position to the second position.
  • the unit controller 30 positions the package holding section 71 at the winding position.
  • the unit controller 30 moves the package holding section 71 from the winding position to the first position by operating the first switching mechanism 60 (the lift-up control).
  • the unit controller 30 moves the package holding section 71 from the winding position to the second position by operating the second switching mechanism 80 (the retreat control).
  • the unit controller 30 After the second switching mechanism 80 has moved the package holding section 71 from the second position to the winding position, the unit controller 30 returns the second switching mechanism 80 to an initial state by operating the first switching mechanism 60.
  • the initial state indicates a state of the second switching mechanism 80 before the second switching mechanism 80 moves the package holding section 71 from the winding position to the second position (a state of the second switching mechanism 80 illustrated in FIG. 5 ).
  • This control by the unit controller 30 will hereinafter be referred to as a "reset control".
  • the unit controller 30 of the present embodiment operates the first switching mechanism 60 and returns the first switching mechanism 60 to an original position (a position of the first switching mechanism 60 illustrated in FIG. 5 ) to return the second switching mechanism 80 to the initial state.
  • the unit controller 30 operates the first switching mechanism 60.
  • the rotation link 73d is rotatable in a clockwise direction
  • the rotation link 73d is rotated in the clockwise direction by operation of the first switching mechanism 60.
  • the lower end 60a of the case of the first switching mechanism 60 is moved downward. That is, a position of the first switching mechanism 60 is moved to the original position (the position of the first switching mechanism 60 illustrated in FIG. 5 ).
  • the tip end 82a of the piston rod 82 in the second switching mechanism 80 is moved in a right direction of FIG. 8 , and the spring 84 is pulled in the right direction. Accordingly, the second switching mechanism 80 is returned to the initial state as illustrated in FIG. 5 .
  • the reset control by the unit controller 30 described above is performed before the first switching mechanism 60 moves the package holding section 71 to the first position.
  • the above-described reset control is performed after the yarn joining operation is performed by the splicer 43 and before a next adjustment of the accumulation amount of the spun yarn 10 in the yarn accumulating device 12 is performed.
  • the reset control is performed after the retreat control has been performed and before a next lift-up control is performed.
  • the unit controller 30 moves the package holding section 71 to the second position by operating the second switching mechanism 80 (step S1).
  • the unit controller 30 moves the yarn joining cart 3 to a predetermined position and causes the splicer 43 to perform the yarn joining operation (step S2).
  • the unit controller 30 determines whether or not a predetermined period of time (for example, 30 seconds) has elapsed after the yarn joining operation (may be after performing the retreat control) (step S3).
  • a predetermined period of time for example, 30 seconds
  • the unit controller 30 performs the reset control (step S4).
  • the operation of the first switching mechanism 60 in the reset control may be one time or a plurality of times. Furthermore, the operation of the first switching mechanism 60 in the reset control may be continuous or intermittent.
  • the unit controller 30 monitors a detection signal transmitted from the accumulation amount sensor 27 and determines whether or not the accumulation amount of the spun yarn 10 in the yarn accumulating device 12 is a predetermined amount or less (step S5).
  • the unit controller 30 performs the lift-up control (step S6).
  • the unit controller 30 returns the second switching mechanism 80 to the initial state. Specifically, in the winding device 13 of the above-described embodiment, after performing the retreat control by the unit controller 30, the reset control is always performed. Further specifically, after performing the retreat control, the unit controller 30 performs the reset control to operate the first switching mechanism 60 (to perform an ON/OFF control) regardless of the accumulation amount of the spun yarn 10 in the yarn accumulating device 12. In such a manner, the second switching mechanism 80 is reliably returned to the initial state. Consequently, the package holding section 71 can be reliably moved (lifted up) from the winding position to the first position at a predetermined timing. That is, the first switching mechanism 60 can be stably operated and the lift-up by the first switching mechanism 60 can be reliably performed.
  • the second switching mechanism 80 in the winding device 13 of the above-described embodiment uses the spring 84 as a member for moving the package holding section 71 from the second position to the winding position.
  • the spring 84 is switched to a contracted state (see FIG. 7 ).
  • the second switching mechanism 80 can return the package holding section 71 from the second position to the winding position.
  • the first switching mechanism 60 is returned to the original position by operating the first switching mechanism 60 by the unit controller 30, and thus the second switching mechanism 80 is returned to the initial state. That is, when operating the first switching mechanism 60 in a state in which the second switching mechanism 80 is not in the initial state as illustrated in FIG. 8 (in the state in which the spring 84 is contracted), since the rotation link 73d is in the movable state in the clockwise direction, the rotation link 73d is rotated in the clockwise direction. With the rotation of the rotation link 73d, the lower end 60a of the case of the first switching mechanism 60 is moved downward. In other words, the first switching mechanism 60 is moved to the original position (the position of the first switching mechanism 60 illustrated in FIG. 5 ).
  • the tip end 82a of the piston rod 82 in the second switching mechanism 80 is moved in the right direction illustrated in FIG. 8 , and the spring 84 is pulled in the right direction. Accordingly, the second switching mechanism 80 can be returned to the initial state as illustrated in FIG. 5 . Consequently, the package holding section 71 can be reliably moved (lifted up) from the winding position to the first position at the predetermined timing. That is, the first switching mechanism 60 can be stably operated.
  • a switching mechanism adapted to move the package holding section 71 from the winding position to the receded position (the first position and the second position) is formed of the first switching mechanism 60 and the second switching mechanism 80, but the present invention is not limited to such an example.
  • the switching mechanism adapted to move the package holding section 71 from the winding position to the receded position may be formed of one or more than three switching mechanisms. Even in this case, if a reset control to return all the switching mechanisms to the initial state is performed by operating at least one switching mechanism, the switching mechanism adapted to move a package away from a contact roller can be stably operated.
  • the first switching mechanism 60 is configured as a double-acting air pressure cylinder.
  • a first switching mechanism may include a single-acting cylinder adapted to move a package holding section from the winding position to the first position and a spring (an elastic member) adapted to move the package holding section from the first position to the winding position. Even with such a configuration, by operating the single-acting cylinder of the first switching mechanism, the first switching mechanism can be returned to an initial state.
  • the package holding section can be reliably moved (lifted up) from the winding position to the first position at a predetermined timing. That is, the first switching mechanism can be stably operated, and the lift-up by the first switching mechanism can be reliably performed.
  • the unit controller 30 of the above-described embodiment performs the reset control after an elapse of a predetermined period of time after performing the retreat control, but the present invention is not limited to such an example.
  • the accumulation amount sensor 27 may detect that the accumulation amount of the spun yarn 10 in the yarn accumulating roller 21 has reached a predetermined amount, which is different from the accumulation amount to perform the lift-up control, and the unit controller 30 may perform the reset control based on a signal from the accumulation amount sensor 27.
  • the spun yarn 10 is fed from the pneumatic spinning device 9 by the yarn accumulating roller 21 adapted to accumulate the spun yarn 10 by winding a certain amount of the spun yarn 10 therearound.
  • a spun yarn may be fed from a pneumatic spinning device by a delivery roller and a nip roller.
  • the spun yarn 10 is disconnected by stopping whirling airflow of the pneumatic spinning device 9 at the time of detecting a yarn defect.
  • a spun yarn may be disconnected by a cutter.
  • a yarn path is arranged such that the spun yarn 10 travels downward from the draft device 7 located in an upper part towards the winding device 13 located in a lower part.
  • the yarn path may be arranged such that a spun yarn travels from the lower part towards the upper part.
  • the traverse guide 76 of the traverse device 93 is commonly driven among the plurality of spinning units 2.
  • Each section of a spinning unit (for example, a draft device, a pneumatic spinning device, a yarn winding device, etc.) may be independently driven in each spinning unit 2.
