  • a yarn defect detection device monitors the presence or absence of a yarn defect of the spun yarn unwound from the yarn supply bobbin, and in this condition, the spun yarn is guided through a number of yarn guides and the like to a traversing device, and the traversing device traverses the yarn and simultaneously winds the yarn on a surface of the winding package that is rotating.
  • the yarn defect is detected, the yarn is cut and a portion containing the yarn defect is removed, and then the yarn having been cut is connected (yarn joining) by a yarn joining device, to restart the winding into the package.
  • the yarn joining device performs the yarn joining, it is necessary that a yarn of the package side and a yarn of the yarn supply bobbin side are guided to the yarn joining device.
  • a suction stream is generated at a distal end of a pipe-shaped yarn guide member to thereby suck and catch a yarn, and then the yarn guide member is swung so that the yarn is guided to the yarn joining device.

  • the winder unit 90 is configured to rewind a spun yarn 20 of a yarn supply bobbin 21 into a package 30.
  • the winder unit 90 includes a yarn joining device 14 that performs the yarn joining, yarn guide pipes (an upper yarn guide pipe 91, a lower yarn guide pipe 92), a tension applying device 12 that applies an adequate tension to the yarn, a clearer 17, and a cutter 16 arranged at the immediately upstream side of the clearer 17.
  • the yarn guide pipes 91 and 92 are connected to a negative pressure source (not shown), and configured such that a suction stream is generated at each of a suction port 91a of the upper yarn guide pipe 91 and a suction port 92a of the lower yarn guide pipe 92.
  • the upper yarn guide pipe 91 is configured to swing up and down about a pivot point 91b.
  • the lower yarn guide pipe 92 is configured to swing up and down about a pivot point 92b.
  • the clearer 17 is configured to detect a yarn defect (yarn fault) by, for example, monitoring the thickness of the yarn 20 that is traveling.
  • the cutter 16 is configured to cut the yarn 20 immediately upon detection of a yarn defect by the clearer 17.
  • a yarn joining operation performed in a case where a yarn defect is detected in the above-described conventional automatic winder will be described.
  • the cutter 16 cuts the yarn 20.
  • a yarn end existing at the downstream side of the cutter 16 is wound into the package 30 that is rotating.
  • a yarn existing at the upstream side of the cutter 16 is sucked and caught by the suction port 92a of the lower yarn catch pipe 92 that stands by at the upstream side of the tension applying device 12.
  • the upper yarn guide pipe 91 is swung up, and additionally the package 30 is rotated in a reverse direction.
  • the yarn end is pulled out from the package 30 and sucked by the suction port 91a of the upper yarn guide pipe 91. This situation is shown in FIG. 20 .
  • the upper yarn guide pipe 91 which is sucking and holding the yarn (upper yarn) of the package 30 side, is swung down. Thereby, the upper yarn of the package 30 side is introduced to the yarn joining device 14.
  • the lower yarn guide pipe 92 which is sucking and holding the yarn (lower yarn) of the yarn supply bobbin 21 side, is swung up. Thereby, the lower yarn of the yarn supply bobbin 21 side is introduced to the yarn joining device 14.
  • the yarn joining device 14 is actuated so that the yarn joining is performed between the upper yarn and the lower yarn, to thereby achieve a continuous state of the yarn between the package 30 and the yarn supply bobbin 21. Performing the yarn joining in the above-described manner enables the winding of the yarn into the package 30 to be continued.
  • the upper yarn guide pipe 91 and the lower yarn guide pipe 92 are swung up and down at different timings. This is because simultaneously swinging the upper yarn guide pipe 91 and the lower yarn guide pipe 92 causes interference between the two yarn guide pipes 91 and 92 that are swinging.

  • the configuration disclosed in Patent Document 1 can reduce the amount of the yarn sucked by the relay pipe (lower yarn guide pipe) in a case where a yarn defect is detected so that the yarn is cut, as compared with the configuration shown in FIG. 17 .
  • a yarn winding machine comprising: a bobbin support part that supports a yarn supply bobbin; a winding part that winds a yarn from the yarn supply bobbin into a package; a yarn joining device arranged between the bobbin support part and the winding part, and configured to perform yarn joining between a yarn of the yarn supply bobbin side and a yarn of the package side under a state where a yarn extending from the yarn supply bobbin to the package is disconnected; a yarn guide part that guides the yarn package side to the yarn joining device under a state where the yarn is disconnected; a yarn catch part arranged so as to face a yarn travel part between the winding part and the yarn joining device, and configured to catch the yarn of the yarn supply bobbin side under a state where the yarn is disconnected.
  • Patent Document 1 Japanese Patent Application Laid-Open No. 2001-192175
  • Patent Document 1 involves a problem that a time required for the yarn joining operation increases to result in deterioration in the production efficiency of the package.
  • the present invention has been made in view of the circumstances described above, and a primary object of the present invention is to provide a yarn winding machine that is able to improve the degree of freedom in a layout, to guide a yarn to a yarn joining device in a short time, and also to reduce the amount of a waste yarn which is generated in yarn joining.
  • a yarn winding machine having the following configuration.
  • the yarn winding machine includes a bobbin support part, a winding part, a yarn joining device, a yarn guide part, a yarn catch part, and a driving part.
  • the bobbin support part supports a yarn supply bobbin.
  • the winding part winds a yarn from the yarn supply bobbin into a package.
  • the yarn joining device is arranged between the bobbin support part and the winding part, and configured to perform yarn joining between a yarn of the yarn supply bobbin side and a yarn of the package side under a state where a yarn extending from the yarn supply bobbin to the package is disconnected.
  • the yarn guide part guides the yarn of the package side to the yarn joining device under a state where the yarn is disconnected.
  • the yarn catch part is arranged so as to face a yarn travel path between the winding part and the yarn joining device, and configured to catch the yarn of the yarn supply bobbin side under a state where the yarn is disconnected.
  • the driving part moves the yarn catch part in such a direction that the yarn caught by the yarn catch part is introduced to the yarn joining device while keeping a condition in which the yarn is across the yarn joining device.
  • the yarn catch part that is configured to catch the yarn of the yarn supply bobbin side under a state where the yarn is disconnected, is arranged at a position facing the yarn travel path between the winding part and the yarn joining device. Therefore, when performing the yarn joining, the yarn can be caught at a position where the yarn is introduced to the yarn joining device. This can shorten a time cycle of the yarn joining. Additionally, since any complicated drive member is not necessary, the entire configuration of the yarn winding machine is simple.
  • the above-described yarn winding machine is configured as follows.
  • the yarn winding machine includes a yarn defect detection device and a yarn disconnecting part.
  • the yarn defect detection device is arranged between the bobbin support part and the winding part, and configured to detect a yarn defect.
  • the yarn disconnecting part puts the yarn between the yarn supply bobbin and the package into a disconnection state, based on a disconnection signal that is supplied when the yarn defect detection device detects a yarn defect.
  • the yarn disconnecting part disconnects the yarn, and the yarn of the yarn supply bobbin side thus disconnected is caught by the yarn catch part. This can shorten a time cycle required for the yarn joining.
  • the yarn disconnecting part is a cutter arranged between the yarn catch part and the yarn defect detection device.
  • disconnection (cutting) of the yarn at a predetermined position is reliably achieved by the cutter. Therefore, catching of the yarn by the yarn catch part is reliably achieved. Furthermore, since the disconnection of the yarn is performed at a predetermined position, the amount of a waste yarn which is generated when the yarn of the yarn supply bobbin side is subjected to the yarn joining can be made constant. This makes management of the waste yarn easy.
  • the yarn catch part is an air suction part configured to catch a yarn by means of an air suction force.
  • the disconnected yarn can be sucked and caught by the air suction force. Additionally, applying the suction force at a time of a winding operation, too, can collect cotton fly generated from the yarn.
  • the yarn catch part may be a clamp portion configured to catch a yarn by gripping the yarn.
  • the clamp portion catches the yarn. Accordingly, cutting and catching of the yarn are reliably achieved.
  • the above-described yarn winding machine may be configured as follows.
  • the yarn catch part is a clamp portion arranged between the yarn joining device and the winding part, and the clamp portion also acts as a yarn disconnecting part by gripping a yarn that is traveling.
  • the yarn catch part simultaneously disconnects and catches the yarn by causing the clamp portion to grip the yarn between the yarn supply bobbin and the winding part.
  • the clamp portion since disconnection of the yarn is achieved by the clamp portion, the yarn end is caught without fail.
  • the above-described yarn winding machine is configured as follows.
  • the yarn guide part is configured to guide the yarn of the package side to the yarn joining device by moving from the package side to the yarn supply bobbin side beyond the yarn joining device under a state where the yarn of the package side is sucked and caught by the yarn guide part.
  • a yarn retraction part is formed in the yarn guide part.
  • the yarn retraction part is configured to retract a yarn extending from the yarn supply bobbin to the yarn catch part, from a trajectory along which the yarn guide part moves so as to guide a yarn to the yarn joining device.
  • Retracting the yarn existing between the yarn supply bobbin and the yarn catch part allows the yarn guide part that is swingable to guide the yarn to the yarn joining device.
  • the yarn retraction part is an inclined portion formed in an advance surface that advances at a time when the yarn guide part moves so as to guide the yarn to the yarn joining device.
  • the yarn existing between the yarn supply bobbin and the yarn catch part is pushed aside and thus retracted by the inclined portion, and then the yarn guide part is moved. This prevents the yarn guide part from being tangled in the yarn. Therefore, the yarn guide part is able to guide the yarn to the yarn joining device.
  • a yarn accumulation device is arranged between the winding part and the yarn joining device.
  • the winding of the yarn into the package is not interrupted during the yarn joining. Therefore, a winding state of the package is not disordered. Moreover, this configuration shortens a time cycle of the yarn joining, which can prevent run-out of the yarn accumulated on the yarn accumulation device. This allows removal of a yarn fault or replacement of a bobbin to be performed without interrupting the winding of the yarn into the package.
  • the above-described yarn winding machine is configured as follows.
  • the yarn guide part includes a yarn sucking and ejecting part and a second yarn catch part.
  • the yarn sucking and ejecting part sucks a yarn of the winding part side and blows off the yarn to a position at an upstream side of the yarn joining device with respect to a yarn winding direction.
  • the second yarn catch part is arranged at an upstream side of the yarn joining device, and configured to catch and introduce the yarn blown off by the yarn sucking and ejecting part to the yarn joining device.
  • the configuration for guiding the yarn is simple.
  • the degree of freedom in a layout of configuration parts is improved.
  • guiding of the yarn to the yarn joining device is completed merely by blowing off the yarn, a time required for the operation for guiding the yarn is shortened and thus the production efficiency of the package is improved.
  • the yarn guide part includes a deflection guide member that guides the yarn blown off by the yarn sucking and ejecting part to the second yarn catch part.
  • the yarn sucking and ejecting part and the second yarn catch part can be freely arranged. This improves the degree of freedom in a layout.
  • the deflection guide member is a tube-like member, in which a slit is formed along a longitudinal direction of a tube.
  • the deflection guide member is arranged at a position deviated from the yarn travel path through which the yarn travels at a time of yarn winding.
  • the deflection guide member having such a tube-like shape allows the yarn to pass through the inside of the tube and thereby reliably guides the yarn to the yarn catch part. Since the slit is formed in the deflection guide member having a tube-like shape, the yarn having been guided to the yarn catch part can be drawn out through the slit. Moreover, since the deflection guide member is not connected with other members, the yarn drawn out through the slit is not in contact with the deflection guide member. In the above-described configuration, at a time of the normal winding, the yarn is able to travel outside the deflection guide member. This can prevent deterioration in the quality of the yarn, which may otherwise be caused by contact with the deflection guide member.
  • the yarn is wound on a predetermined portion of the yarn accumulation device.
  • the yarn end of the yarn wound on the yarn accumulation device is also located at the predetermined portion at a time of yarn disconnection. Accordingly, by sucking this predetermined portion, the yarn end can be caught for the yarn joining. Therefore, a large suction port such as a suction mouth for sucking and catching the yarn end from the package is not necessary. This makes the shape of the yarn guide part simple, and thus the degree of freedom in a layout is improved. Additionally, since the suction port can be made small, the air consumption is reduced.
  • the yarn guide part sucks and blows off the yarn of the winding part side that is wound on the yarn accumulation device.
  • FIG. 1 is a side view showing an outline of a winder unit 2 included in an automatic winder (yarn winding machine) according to a first embodiment of the present invention.
  • the automatic winder of this embodiment is configured with a number of winder units 2 arranged side by side.
  • This automatic winder includes a machine management device (not shown) and a blower box (not shown).
  • the machine management device collectively manages the winder units 2.
  • the blower box includes a compressed air source and a negative pressure source.
  • the winder unit 2 mainly includes a bobbin support part 7 and a winding part 8.
  • the winder unit 2 is configured to unwind a yarn (spun yarn) 20 from a yarn supply bobbin 21 that is supported on the bobbin support part 7 and rewind the yarn into a package 30.
  • FIG. 1 shows a state of the winder unit 2 at a time of normal winding.
  • the "time of normal winding" indicates a state where the yarn is continuous between the yarn supply bobbin 21 and the package 30 and additionally the yarn is being unwound from the yarn supply bobbin 21 and wound into the package 30.
  • the bobbin support part 7 is configured to hold the yarn supply bobbin 21 in a substantially upright state.
  • the bobbin support part 7 is also configured to discharge the yarn supply bobbin 21 that is empty.

  • the traverse drum 24 is configured to traverse the yarn 20 and drive the wound bobbin 22.
  • the traverse drum 24 is arranged opposed to the wound bobbin 22.
  • the traverse drum 24 is driven in rotation, and thereby the wound bobbin 22 is accordingly rotated.
  • This enables the yarn 20 accumulated on a yarn accumulation device 18, which will be described later, to be wound on the wound bobbin 22.
  • a traverse groove (not shown) is formed in an outer circumferential surface of the traverse drum 24.
  • the traverse groove allows the yarn 20 to be traversed (cross-wound) with a predetermined width.
  • the yarn 20 is wound on the wound bobbin 22 while being traversed, to form the package 30 having a predetermined length and a predetermined shape.
  • the terms "upstream side” and “downstream side” mean the upstream side and the downstream side with respect to a direction of traveling of the yarn.
  • Each of the winder units 2 includes a control part 25.
  • the control part 25 is composed of hardware such as a CPU, a ROM, and a RAM (not shown), and software such as a control program accumulated in the RAM.
  • the hardware and the software cooperate with each other, to thereby control each configuration part of the winder unit 2.
  • the control part 25 included in each winder unit 2 is configured to communicate with the machine management device. Accordingly, the machine management device can collectively manage operations of the plurality of winder units 2 included in the automatic winder.
  • the winder unit 2 also includes various devices provided in a yarn travel path between the bobbin support part 7 and the winding part 8. More specifically, in the yarn travel path, an unwinding assist device 10, a lower yarn blow-up part 11, a tension applying device 12, an upper yarn catch part (second yarn catch part) 13, a yarn joining device 14, a yarn trap (yarn catch part) 15, a cutter (yarn disconnecting part) 16, a clearer (yarn defect detection device) 17, an upper yarn pull-out part (yarn sucking and ejecting part) 48, and a yarn accumulation device 18, are arranged in this order from the bobbin support part 7 side toward the winding part 8 side.

  • the unwinding assist device 10 assists the unwinding of the yarn 20 by bringing a movable member 40 into contact with a balloon, which is generated above the yarn supply bobbin 21 as a result of the yarn 20 being unwound from the yarn supply bobbin 21 and thrown around, and thereby appropriately controlling the size of the balloon.
  • the lower yarn blow-up part 11 is an air sucker device, which is configured to blow up a lower yarn of the yarn supply bobbin 21 side toward the yarn joining device 14 side at a time of replacing the yarn supply bobbin 21 (details will be given later).
  • the tension applying device 12 applies a predetermined tension to the yarn 20 that is traveling.
  • the tension applying device 12 is configured as a gate type in which a movable comb is arranged relative to a fixed comb.
  • the movable comb is configured to be swung by a rotary type solenoid such that the combs are brought into engagement or disengagement.
  • a configuration of the tension applying device 12 is not limited to this.
  • a disk type tension applying device is also adoptable.
  • the upper yarn catch part 13 is arranged near the yarn joining device 14 (to be exact, at the immediately upstream side of the yarn joining device 14).
  • the upper yarn catch part 13 is configured to suck and catch an upper yarn of the yarn accumulation device 18 side at a time of yarn joining (details will be given later).
  • the yarn trap 15 is arranged between the winding part 8 and the yarn joining device 14 (to be exact, at the upstream side of the cutter 16 and at the immediately downstream side of the yarn joining device 14).
  • a distal end of the yarn trap 15 is formed as a tube-like member, which is provided close to the travel path of the yarn 20.
  • the yarn trap 15 is arranged such that the distal end thereof is directed to the yarn travel path, and connected to a negative pressure source (not shown). In this configuration, the suction air stream is generated at the distal end of the yarn trap 15, and thereby dusts such as cotton fly adhering to the traveling yarn 20 can be sucked and removed. In this manner, the yarn trap 15 is formed as an air suction part.
  • the yarn trap 15 sucks and catches the lower yarn of the yarn supply bobbin 21 side (details will be given later).
  • the clearer 17 is configured to detect a yarn defect (yarn fault) such as a slub by monitoring a yarn thickness of the yarn 20.
  • a yarn defect such as a slub
  • the clearer 17 transmits a disconnection signal to, for example, the control part 25.
  • the disconnection signal instructs to cut and remove the yarn defect.
  • the cutter 16 is arranged at the immediately upstream side of the clearer 17, for immediately cutting the yarn 20 in response to the disconnection signal.
  • the yarn joining device 14 performs yarn joining between the lower yarn of the yarn supply bobbin 21 side and the upper yarn of the yarn accumulation device 18 side when the yarn is disconnected between the yarn supply bobbin 21 and the package 30, which occurs, for example, at a time of yarn cutting in which the clearer 17 detects a yarn defect so that the cutter 16 cuts the yarn, at a time of yarn breakage in which the yarn being unwound from the yarn supply bobbin 21 is broken, or at a time of replacing the yarn supply bobbin 21.
  • the yarn joining device 14 one using fluid such as compressed air, mechanical one, or the like, is adoptable.
  • the upper yarn pull-out part 48 is an air sucker device, and configured to pull out the upper yarn of the yarn accumulation device 18 side toward the yarn joining device 14 side at a time of the yarn joining (details will be given later).
  • the yarn accumulation device 18 is configured to wind up and temporarily accumulate the yarn 20 unwound from the yarn supply bobbin 21. In this manner, the yarn accumulation device 18 is interposed between the bobbin support part 7 and the winding part 8, and a certain amount of the yarn 20 is accumulated on the yarn accumulation device 18. Accordingly, even when the unwinding of the yarn from the yarn supply bobbin 21 is interrupted for some reason (for example, during the yarn joining operation), the winding part 8 is able to wind the yarn accumulated on the yarn accumulation device 18. Therefore, the winding of the yarn 20 into the package 30 can be continued. Thus, since a winding operation of the winding part 8 is not interrupted by the yarn joining operation or the like, the package 30 can be produced stably at a high speed.
  • sucking and catching of the yarn from the package 30 is not performed in every yarn joining operation. This can prevent occurrence of disorder in a surface of the package 30. Moreover, since occurrence of a yarn breakage in the winding part 8 is reduced, falling of the yarn onto an edge surface of the package 30 or occurrence of a failure in the winding shape is prevented.
  • a bobbin feeder 26 of magazine type is arranged at the front side of the winder unit 2.
  • the bobbin feeder 26 includes a rotary magazine can 27.
  • the magazine can 27 is configured to hold a plurality of extra yarn supply bobbins 21.
  • the bobbin feeder 26 intermittently drives and rotates the magazine can 27, and thereby feeds a new yarn supply bobbin 21 to the bobbin support part 7.
  • the bobbin feeder 26 includes a yarn end holder 28 for sucking and holding a yarn end of the yarn supply bobbin 21 held on the magazine can 27.
  • the yarn accumulation device 18 mainly includes a yarn accumulation roller 32 and a roller drive motor 33.
  • the yarn accumulation roller 32 is a substantially cylindrical member and configured to accumulate the yarn 20 by winding the yarn 20 on an outer circumferential surface thereof.
  • the roller drive motor 33 is configured to drive and rotate the yarn accumulation roller 32 around the central axis thereof. An operation of the roller drive motor 33 is controlled by the control part 25.
  • an end portion of the yarn accumulation roller 32 at the side where the roller drive motor 33 is arranged will be called a proximal end portion, and the opposite end portion will be called a distal end portion.
  • a proximal side taper portion 32a is formed in the proximal end portion of the yarn accumulation roller 32.
  • the proximal side taper portion 32a has a tapered shape whose diameter increases toward an end portion.
  • a distal side taper portion 32b is formed in the distal end portion of the yarn accumulation roller 32.
  • the distal side taper portion 32b has a tapered shape whose diameter increases toward an end portion. Forming such taper portions prevents the yarn 20 from slipping off from the end portions of the yarn accumulation roller 32.
  • a portion having a cylindrical shape (a portion having a substantially constant diameter) will be called a cylindrical portion 32c.
  • the cylindrical portion 32c also has an extremely small taper for moving the accumulated yarn toward the downstream side.
  • a guide tube 34 of the upper yarn pull-out part 48 is arranged near a boundary portion between the proximal side taper portion 32a and the cylindrical portion 32c of the yarn accumulation roller 32 (a configuration of the upper yarn pull-out part 48 will be described later).

  • the yarn of the yarn supply bobbin 21 side is introduced into the guide tube 34 through the other end portion (ejection side end portion 34b) of the guide tube 34, and then pulled out from the suction side end portion 34a toward the surface of the yarn accumulation roller 32.
  • the guide tube 34 guides the yarn 20 of the yarn supply bobbin 21 to the surface of the yarn accumulation roller 32.
  • the yarn accumulation roller 32 having the yarn 20 wound thereon is rotated in one direction, and thereby a tensile force is applied to the yarn 20 existing at the upstream side (yarn supply bobbin 21 side) of the yarn accumulation device 18.
  • This enables the yarn 20 to be unwound from the yarn supply bobbin 21 and wound on the surface of the yarn accumulation roller 32.
  • the yarn 20 is guided to the boundary portion between the proximal side taper portion 32a and the cylindrical portion 32c. Therefore, while the yarn 20 is sequentially wound on the cylindrical portion 32c, the yarn 20 pushes up a preceding yarn layer from the proximal end portion side.
  • the yarn 20 accumulated on the yarn accumulation roller 32 is pushed by the newly wound yarn 20, and sequentially fed toward the distal end portion side on the surface of the cylindrical portion 32c.

  • An ejection port of the air ejection nozzle 49 is formed such that air is ejected toward the ejection side end portion 34b (such that air is ejected in a direction away from the surface of the yarn accumulation roller 32). Accordingly, when the compressed air is ejected through the air ejection nozzle 49, an air stream flowing toward the ejection side end portion 34b is generated in the guide tube 34. As a result, air is ejected from the ejection side end portion 34b. On the other hand, along with the air stream generated in the guide tube 34, a suction stream is generated in the opposite end portion (suction side end portion 34a).
  • the control part 25 puts the electromagnetic valve 51 into the open state so that the compressed air is supplied through the air ejection nozzle 49 into the guide tube 34. Under this condition, the control part 25 appropriately controls the roller drive motor 33, thereby causing a reverse rotation of the yarn accumulation roller 32. As a result, a yarn end is unwound from the proximal end portion side of the cylindrical portion 32c of the yarn accumulation roller 32. This yarn end is sucked by the suction stream generated in the suction side end portion 34a of the guide tube 34, and introduced into the guide tube 34.
  • the suction port 91a of the upper yarn guide pipe 91 for sucking and catching a yarn end of a yarn wound into the package 30 is enlarged with respect to a width direction of the package.
  • the reason therefor is as follows. Since the yarn is traversed when being wound on the surface of the package 30, where on the package 30 with respect to the width direction thereof the yarn end of the yarn wound into the package 30 is positioned is uncertain after the clearer 17 detects a yarn defect so that the cutter 16 cuts the yarn or after the yarn of the yarn supply bobbin 21 is fully wound. Therefore, in order to reliably suck and catch the yarn end, it is necessary to generate the suction stream throughout the entire width of the package 30.
  • the yarn 20 is regularly wound on the yarn accumulation roller 32 while being orderly arranged from the boundary portion between the cylindrical portion 32c and the proximal side taper portion 32a.
  • the guide tube 34 guides the yarn of the yarn supply bobbin 21 side to the boundary portion between the cylindrical portion 32c and the proximal side taper portion 32a. Accordingly, after the clearer 17 detects a yarn defect so that the cutter 16 cuts the yarn or after the yarn of the yarn supply bobbin 21 is fully wound, the yarn end of the yarn wound on the yarn accumulation roller 32 is always positioned near the boundary portion between the cylindrical portion 32c and the proximal side taper portion 32a.
  • the yarn end can be reliably sucked. That is, by generating the suction stream in the guide tube 34, the yarn end can be reliably sucked.
  • an enlarged suction port for sucking the upper yarn is not required. This enables a suction stream sufficient for sucking the upper yarn to be generated by less energy.
  • the yarn end sucked into the guide tube 34 is, along with the air stream generated in the guide tube 34, blown out from the ejection side end portion 34b. Air ejection from the ejection side end portion 34b is oriented toward a position where a yarn inlet 61 of a deflection guide member 60 is arranged.
  • the deflection guide member 60 is a curved tube-like member having the yarn inlet 61 at one end side thereof and a yarn outlet 62 at the other end side thereof. Air ejected from the ejection side end portion 34b of the guide tube 34 flows through the yarn inlet 61 into the deflection guide member 60, and is guided through a curved path while passing through the inside of the curved deflection guide member 60, and then is discharged through the yarn outlet 62 to the outside of the deflection guide member 60.
  • the upper yarn 20b blown out together with the air ejected from the upper yarn pull-out part 48 is, along with an air stream flowing in the curved path inside the deflection guide member 60, guided from the yarn inlet 61 to the yarn outlet 62, as shown in FIG. 11 .
  • the upper yarn pull-out part 48 is able to blow off the upper yarn (the yarn of the winding part side) and guides the upper yarn to a position at the upstream side of the yarn joining device 14.

  • the control part 25 performs a control to close the suction stream generation port with the lid 13a. This can prevent air from flowing into the upper yarn catch part 13, and therefore can prevent wasteful consumption of energy.
  • a configuration in which, for example, an air flow is controlled by means of an electromagnetic valve may be also adoptable.
  • the deflection guide member 60 has a slit 63 through which the outside and inside of the deflection guide member 60 are communicated with each other.
  • the slit 63 is formed along a longitudinal direction of the tube-like deflection guide member 60, and connects the yarn inlet 61 and the yarn outlet 62 to each other.
  • the deflection guide member 60 has a substantially U-like shape, and the slit 63 is formed along an inner portion of this U-like shape.
  • the upper yarn 20b drawn out from the deflection guide member 60 is further sucked by the upper yarn catch part 13, and thereby the upper yarn 20b can be introduced to the yarn joining device 14, as shown in FIG. 13 .
  • the upper yarn 20b is guided to a position at the upstream side of the yarn joining device 14 by means of the upper yarn pull-out part 48, the deflection guide member 60, and the upper yarn catch part 13. Accordingly, it can be considered that the upper yarn pull-out part 48, the deflection guide member 60, and the upper yarn catch part 13, form an upper yarn guide part (yarn guide part).
  • the air stream is used to blow off the upper yarn 20b and guide the upper yarn 20b to the upstream side of the yarn joining device 14.
  • This enables the upper yarn to be quickly guided with a simple configuration, as compared with, for example, an upper yarn guide member (the upper yarn guide pipe 91 shown in FIG. 17 ) included in the conventional winder unit. Therefore, a time required for the yarn joining operation is shortened, and thus the production efficiency of the package 30 is improved.
  • control part 25 stops the reverse rotation of the yarn accumulation roller 32 and additionally puts the electromagnetic valve 51 into a closed state. Then, the control part 25 closes the lid 13a of the upper yarn catch part 13. Then, the control part 25 actuates the yarn joining device 14, thus performing yarn joining between the upper yarn 20b and the lower yarn 20a.
  • the control part 25 starts a positive rotation of the yarn accumulation roller 32, thus starting to unwind the yarn from the new yarn supply bobbin 21.
  • the control part 25 drives the yarn trap 15 to a position close to the yarn travel path, and restarts to suck and remove cotton fly.

  • the upper yarn 20b is drawn out from the inside of the deflection guide member 60. Accordingly, at a time of the normal winding (the state shown in FIG. 1 ), the yarn 20 does not pass through the inside of the deflection guide member 60.
  • the yarn 20 might be in contact with the deflection guide member 60 and thus damaged to deteriorate the quality of the yarn.
  • the yarn 20 is not in contact with deflection guide member 60 during the normal winding operation. Therefore, deterioration in the quality of the yarn is prevented.
  • the deflection guide member 60 is not connected with other members. More specifically, the deflection guide member 60 is arranged such that the yarn inlet 61 of the deflection guide member 60 is spaced apart from the upper yarn pull-out part 48. Likewise, the deflection guide member 60 is arranged such that the yarn outlet 62 of the deflection guide member 60 is spaced apart from the upper yarn catch part 13. In this manner, a space is formed between the deflection guide member 60 and the other members. Therefore, the yarn 20 drawn out from the deflection guide member 60 is able to travel without any contact with the deflection guide member 60. In this point as well, damage to the yarn 20 which may be caused by contact with the deflection guide member 60 is prevented at a time of the normal winding. Thus, deterioration in the quality of the yarn is prevented.
  • the yarn 20 is blown off and thereby guided. Therefore, a member driven into large movement, such as the yarn guide pipes 91 and 92 shown in FIG. 17 , is not necessary. Accordingly, the configuration of the automatic winder is simplified, and additionally the degree of freedom in a layout of configuration parts is increased. Furthermore, in this embodiment, a path through which the upper yarn 20b is guided is curved because of the deflection guide member 60. Therefore, even though a direction in which the yarn is blown out from the upper yarn pull-out part 48 is not oriented to the position where the upper yarn catch part 13 is arranged, the upper yarn 20b can be guided to the upper yarn catch part 13. Thus, devising the shape of the deflection guide member 60 allows a free layout of the positions of the upper yarn pull-out part 48 and the upper yarn catch part 13.

Therefore, the operation for blowing the lower yarn 20a upward by the lower yarn blow-up part 11 is not necessary. In this point, this operation is different from the operation for replacing the yarn supply bobbin 21. Accordingly, in the configuration of this embodiment, when the yarn is disconnected between the yarn supply bobbin 21 and the package 30, the yarn end of the yarn supply bobbin 21 side is, at the downstream side of the yarn joining device 14, caught by the yarn trap 15.
  • the configuration of this embodiment can minimize the amount of a waste yarn which is generated when the yarn joining operation is performed upon detection of a yarn defect.

Under this condition, the reverse rotation of the yarn accumulation roller 32 is continued for a predetermined time period. Thereby, the portion containing the yarn defect, which has been wound on the yarn accumulation roller 32, is pulled out and sucked by the upper yarn catch part 13. Thus, the portion containing the yarn defect detected by the clearer 17 can be removed. Then, the control part 25 actuates the yarn joining device 14, to perform yarn joining.

Moreover, since the disconnection (cutting) of the yarn at a predetermined position is reliably achieved by the cutter 16, catching of the yarn by the yarn trap 15 is reliably achieved. Furthermore, since the disconnection of the yarn is performed at a predetermined position, the amount of the waste yarn which is generated when the yarn of the yarn supply bobbin 21 side is subjected to the yarn joining can be made constant.

  • FIG. 14 shows a situation where, in a case where the clearer 17 detects a yarn defect so that the cutter 16 cuts the yarn 20, the lower yarn 20a is sucked and held by the yarn trap 15 while the upper yarn guide pipe 91 is swung up to suck and catch the upper yarn 20b.
  • the upper yarn guide pipe 91 if the upper yarn guide pipe 91 is swung down in order to guide the upper yarn 20b to the yarn joining device 14, the upper yarn guide pipe 91 would move in a trajectory on which the lower yarn 20a between the yarn trap 15 and the yarn supply bobbin 21 exists.
  • the upper yarn guide pipe 91 having the conventional configuration is swung down, this upper yarn guide pipe 91 would be tangled in the lower yarn 20a, which may hinder introduction of the upper yarn 20b to the yarn joining device 14.
  • a yarn retraction part is formed in the upper yarn guide pipe 91.
  • the yarn retraction part temporarily retracts the lower yarn 20a extending to the yarn trap 15 from the yarn supply bobbin 21.
  • an advance surface 91c that advances at a time when the upper yarn guide pipe 91 is swung down is configured as an inclined portion. Accordingly, when the upper yarn guide pipe 91 is swung down, the lower yarn 20a can be pushed aside by the advance surface 91c that is configured as the inclined portion. This allows the upper yarn guide pipe 91 to pass without being tangled in the lower yarn 20a. As a result, the upper yarn 20b can be introduced to the yarn joining device 14.
  • a mechanism for retracting the lower yarn 20a at a time when the upper yarn guide pipe 91 is swung down is provided independently of the upper yarn guide pipe 91.
  • the automatic winder of this modification is configured as follows.
  • the upper yarn guide pipe 91 serving as the yarn guide part is configured to guide the yarn of the package 30 side to the yarn joining device 14 by swinging from the package 30 side to the yarn supply bobbin 21 side beyond the yarn joining device 14 under a state where the yarn of the package 30 side is sucked and caught by the upper yarn guide pipe 91.
  • the yarn retraction part is formed in the yarn guide part.
  • the yarn retraction part is configured to retract the yarn extending from the yarn supply bobbin to the yarn catch part, from the trajectory along which the upper yarn guide pipe 91 is swung so as to guide the upper yarn 20b to the yarn joining device 14.
  • the yarn retraction part is an inclined portion formed in the advance surface that advances at a time when the yarn guide part is swung so as to guide the yarn to the yarn joining device.
  • a configuration of this modification is the same as that of the winder unit 100 shown in FIG. 14 , except that a clamp portion is provided instead of the yarn trap 15.
  • the clamp portion is configured to grip the yarn.
  • the clamp portion is arranged such that it is not in contact with a yarn path at a time of the normal winding.
  • the clamp portion is configured to grip the yarn between the clearer 17 and the yarn joining device 14 in response to a control signal supplied from the control part 25.
  • the clamp portion is configured to be moved in the direction away from the yarn path by the driving part.
  • the control part 25 causes the cutter 16 to cut the yarn, and simultaneously transmits the control signal to the clamp portion to thereby cause the clamp portion to grip the yarn end of the lower yarn after the cutting. Under this condition, the control part 25 causes the driving part to retract the clamp portion. As a result, the yarn end gripped by the clamp portion is directly introduced to the yarn joining device 14.
  • the yarn catch part is the clamp portion configured to catch the yarn by gripping the yarn.
  • the clamp portion catches the yarn. Accordingly, cutting and catching of the yarn are reliably achieved.
  • a configuration of this modification is the same as that of the winder unit 100 shown in FIG. 14 , except that the clamp portion is provided instead of the yarn trap 15 and that the cutter 16 is not provided.
  • the control part 25 transmits the control signal to the clamp portion, to cause the clamp portion to grip the yarn that is traveling.
  • the yarn is torn at a position between the clamp portion and the winding part 8.
  • the control part 25 causes the driving part to retract the clamp portion.
  • the yarn end gripped by the clamp portion is directly introduced to the yarn joining device 14. In this manner, the yarn can be disconnected by the clamp portion. Therefore, it can be said that the clamp portion of this modification also acts as the yarn disconnecting part.
  • the clamp portion serves as both the yarn disconnecting part and the yarn catch part, thereby enabling the disconnected yarn to be reliably caught. That is, in a configuration in which the yarn is cut by a cutter, gripping of the yarn may be failed if a timing when the cutter cuts the yarn and a timing when the clamp portion grips the yarn are not in synchronization. In this respect, in the above-described configuration in which the yarn is disconnected by causing the clamp portion to grip and tear the yarn, the yarn has been already gripped at the time point when the yarn is disconnected, and therefore no failure in gripping the yarn occurs. Accordingly, the yarn disconnected upon detection of a yarn defect can be reliably introduced to the yarn joining device 14.
  • the yarn catch part is the clamp portion arranged between the yarn joining device and the winding part, and the clamp portion also acts as the yarn disconnecting part by gripping the yarn that is traveling.
  • the yarn catch part simultaneously disconnects and catches the yarn by causing the clamp portion to grip the yarn between the yarn supply bobbin and the winding part.
  • the clamp portion since disconnection of the yarn is achieved by the clamp portion, the yarn end is caught without fail.
  • a winder unit 100 included in an automatic winder according to this embodiment includes a yarn accumulation device of different type from that of the above-described first embodiment.
  • this yarn accumulation device 64 will be described with reference to FIG. 16 .
  • the yarn accumulation device 64 includes a rotation shaft casing 70, a yarn accumulation part 71, and a yarn guide part 72.
  • the rotation shaft casing 70 includes a cylindrical tube portion 78 that is open at the upper side thereof, and a flange portion 79 that is formed at an open end portion of the tube portion 78.
  • the upper yarn pull-out part 48 is arranged at the immediately upstream side of the yarn accumulation device 64.
  • the yarn accumulation part 71 is arranged above the flange portion 79.
  • the yarn accumulation part 71 includes a support plate 81 having a disk shape, a plurality of rod members 82 that protrude upward from the support plate 81, and a mounting plate 83 having a disk shape to which distal end portions of the plurality of rod members 82 are connected.
  • the yarn accumulation part 71 is arranged such that there is a gap between the support plate 81 and the flange portion 79.
  • a winding tube 75 which will be described later, is rotatable within the gap.
  • the plurality of rod members 82 are arranged side by side at regular intervals on the circumference of a circle that is perpendicular to the vertical direction. These rod members 82 define a substantially cylindrical shape of the yarn accumulation part 71.
  • the yarn 20 is wound on an outer circumferential portion of the yarn accumulation part 71 having a substantially cylindrical shape defined by the plurality of rod members 82. Thereby, the yarn 20 is accumulated on the yarn accumulation part 71.
  • the yarn guide part 72 is arranged within the rotation shaft casing 70.
  • an introduction hole 80 is formed in a lower portion (at the end opposite to the yarn accumulation part 71 side) of the tube portion 78.
  • the guide tube 34 of the upper yarn pull-out part 48 is connected to the introduction hole 80.
  • the yarn 20 pulled out from the yarn supply bobbin 21 is guided to the introduction hole 80 by the guide tube 34, and led through the introduction hole 80 to the yarn guide part 72.
  • the rotation shaft casing 70 and a rotation shaft 73 are arranged within the tube portion 78.
  • the rotation shaft 73 is mounted to the yarn accumulation part 71 in a relatively rotatable manner.
  • a servomotor (yarn accumulation driving part) 55 is incorporated between the rotation shaft 73 and the tube portion 78, and thus the positive rotation and the reverse rotation of the rotation shaft 73 are allowed.
  • a yarn passage 74 in the shape of an axial hole is provided at the center of the rotation shaft 73.
  • a winding tube (winding means) 75 having a cylindrical shape is fixed to one end of the rotation shaft 73 (an end portion thereof opposite to the introduction hole 80 side).
  • the winding tube 75 is slightly inclined upward, and obliquely extends out through the gap between the rotation shaft casing 70 (flange portion 79) and the support plate 81.
  • a part of a distal end portion of the winding tube 75 slightly protrudes out from the rotation shaft casing 70.
  • the winding tube 75 is rotatable integrally with the rotation shaft 73.
  • the inside of the winding tube 75 is connected to the yarn passage 74.
  • the yarn 20 is led through the introduction hole 80 of the yarn guide part 72 into the rotation shaft casing 70, and then passes through the yarn passage 74 and the inside of the winding tube 75, and then is discharged from the distal end of the winding tube 75.
  • the yarn 20 is guided to a side surface portion of the yarn accumulation part 71. Accordingly, when the servomotor 55 is driven in a positive direction, the winding tube 75 is rotated together with the rotation shaft 73, thus winding the yarn 20 around the side surface portion.
  • each of the plurality of rod members 82 is arranged such that it is inclined more inward of the yarn accumulation part 71 at a location farther from its end at the support plate 81 side and closer to its end at the mounting plate 83 side.
  • Such inclination of the rod member 82 causes the yarn wound on the yarn accumulation part 71 to move upward in a sliding manner. Accordingly, when the winding tube 75, which will be described later, continuously wind the yarn 20, the yarn wound on the inclined portion moves upward.
  • the yarn 20 is accumulated while being orderly arranged into a spiral shape.
  • the upper yarn pull-out part 48 includes the guide tube 34 and the air ejection nozzle 49.
  • the air ejection nozzle 49 is connected to the electromagnetic valve 51 that is controlled by the control part 25.
  • the electromagnetic valve 51 is connected to the compressed air source 46.
  • An air ejection port of the air ejection nozzle 49 is formed such that air is ejected toward the upstream side with respect to the direction of traveling of the yarn.
  • the control part 25 stops the servomotor 55 and puts the electromagnetic valve 51 into the open state, to generate an air stream in the guide tube 34. Thereby, the yarn can be pulled out from the yarn accumulation device 64.
  • a direction in which air is ejected from the upper yarn pull-out part 48 is oriented to a position where the yarn inlet 61 of the deflection guide member 60 is arranged.
  • the above-described configuration enables the upper yarn of the yarn accumulation device 64 side to be guided to the yarn joining device 14.
  • the rod members 82 are inclined in order that the yarn is wound while being orderly arranged in the yarn accumulation part 71.
  • a member that actively transfers the yarn upward may be provided instead of inclining the rod members.
  • a yarn in a yarn accumulation part is actively transferred upward by means of a roller member.
  • the roller drive motor 33 causes a reverse rotation of the yarn accumulation roller 32.
  • the upper yarn pull-out part 48 pulling out the upper yarn 20b exerts a sufficiently strong force, it may be acceptable to merely put the roller drive motor 33 into a neutral mode.
  • the lower yarn 20a is firstly guided and then the upper yarn 20b is guided.
  • the upper yarn 20b may be firstly guided.
  • the number of yarn guide pipes is at most one. Therefore, the problem of interference between yarn guide pipes does not occur. Accordingly, in the automatic winders according to the above-described embodiments or modifications thereof, the lower yarn 20a and the upper yarn 20b can be simultaneously guided.
  • the yarn trap 15 can be driven in the direction toward and away from the yarn travel path.
  • this configuration may be omitted, and instead the yarn trap 15 may be fixed at a position away from the yarn travel path (position that allows the lower yarn 20a to be introduced to the yarn joining device 14).
  • such a configuration cannot bring the yarn trap 15 close to the yarn travel path at a time of the normal winding. Therefore, it is difficult to strongly apply the suction stream to the yarn 20, and there is a possibility that cotton fly adhering to the yarn 20 cannot be reliably removed.
  • Such a configuration also involves a possibility that, when a yarn defect is detected so that the yarn 20 is cut, a yarn end of the lower yarn cannot be caught. Accordingly, it is preferable that the yarn trap 15 can be driven in the direction toward and away from the yarn travel path, as described in the embodiments above.
  • the shape of the deflection guide member 60 is not limited to the one adopted in the above-described embodiments. Any appropriate shape is adoptable, as long as the air ejected from the upper yarn pull-out part 48 can be appropriately guided to the upper yarn catch part 13.
  • the upper yarn 20b can be guided to the upper yarn catch part 13 without the deflection guide member 60. In such a case, therefore, the deflection guide member 60 can be omitted.
  • each winder unit 2 includes the control part 25, and instead a plurality of winder units may be controlled by a single control part.
  • the single control part 25 collectively controls a plurality of members.
  • an individual control part may be provided corresponding to each member to be controlled.
  • the control part 25 is composed of hardware and software. However, it may be acceptable that the function of the control part 25 is partially or wholly implemented by hardware dedicated therefor.
  • the yarn supply bobbin 21 is fed to the winder unit 2 by means of the bobbin feeder 26 of magazine type.
  • this configuration is not limiting.
  • a tray having the yarn supply bobbin 21 set thereon may be transported along an appropriate path, to thereby feed the yarn supply bobbin 21 to the winder unit 2.
  • the winding part 8 is configured to traverse the yarn 20 by means of the traverse drum 24.
  • an arm-type traverse mechanism may be adopted to traverse the yarn 20.
  • the present invention is not limited to an automatic winder, and the present invention is applicable to other types of yarn winding machines including a yarn joining device.
