Definitions

  • the present invention relates mainly to a yarn pull-out device that pulls out a yarn from a winding part.
  • a yarn pull-out device is conventionally known that pulls out a yarn end of a package for performing yarn joining or the like.
  • the yarn pull-out device includes a wound yarn catch and guide device and a detection part.
  • the wound yarn catch and guide device sucks and catches the yarn from the package.
  • the detection part detects the yarn caught by the wound yarn catch and guide device. By detecting the yarn by the detection part (or after a predetermined time elapsed from detection) the wound yarn catch and guide device allows the sucking and catching operation to be completed.
  • Patent Documents 1 and 2 disclose this kind of a yarn pull-out device.
  • WO 2005/070800 A1 shows optical sensors mounted on a light passing part of the yarn pull-out device.
  • a yarn pull-out device of Patent Document 1 has a suction nozzle that catches a yarn of a package. This suction nozzle is configured to swing. A sensor (detection part) is provided within a suction port of a distal end of a suction nozzle. Patent Document 2 also discloses that a yarn pull-out device has a sensor (detection part) provided at a distal end of a suction mouth that catches a yarn of a package.
  • Wiring for the supply of electricity and the input/output of data are connected to a detection part for detecting a yarn.
  • a detection part for detecting a yarn.
  • it is necessary to devise the attaching position and the length of wiring and the like so that the wound yarn catch and guide device can move. Even when the attaching position of wiring is devised, loading on wiring is less likely to be prevented. Then, a short lifetime of wiring cannot be prevented.
  • a yarn pull-out device in Patent Document 1 significantly involves the above-described problem because a detection part is attached in the farthest position from a pivot shaft (the position at which a movement distance is the largest).
  • a detection part is arranged in a part having a short movement distance (near the pivot shaft or downstream side), and thereby the above-described problem can be reduced. In this case, however, it takes a long time until a wound yarn catch and guide device catches and detects a yarn. This leads to an increase in a time for such as the yarn joining.
  • 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 pull-out device capable of quickly detecting a pulled out yarn without applying load on wiring of a detection part for detecting a yarn pulled out from a package.
  • a yarn pull-out device that pulls out a yarn from a winding part for winding the yarn to form a package. That is, the yarn pull-out device includes a wound yarn catch and guide device and a detection part.
  • the wound yarn catch and guide device has a move and catch part that moves from a waiting position to a catching position in the winding part side, sucks and catches a wound yarn that is a yarn in the winding part side.
  • the detection part detects a wound yarn caught by the wound yarn catch and guide device.
  • the move and catch part approaches the detection part by moving from the waiting position to the catching position.
  • the detection part detects the presence or absence of the wound yarn within the move and catch part that is moved to the catching position.
  • the detection part is arranged at the different position from the move and catch part. Thereby, no load is applied to wiring that is connected to the detection part even when the move and catch part is moved. Consideration for load applied to wiring is not necessary and therefore the wound yarn can be detected at any position.
  • the yarn pull-out device is configured as follows. That is, the detection part includes a light emitting part and a light receiving part.
  • the light emitting part emits light toward a detecting position within the move and catch part.
  • the light receiving part receives light which is reflected at the detecting position from emitted light from the light emitting part or which is passed through the detecting position from emitted light from the light emitting part.
  • a light passing part for passing through light emitted from the light emitting part is provided in the move and catch
  • a light sensor is adopted for a detection part and thereby a wound yarn within a move and catch part can be easily detected from outside of the move and catch part.
  • the yarn pull-out device is configured as follows. That is, the move and catch part includes a suction port and a pipe part.
  • the suction port approaches an outer circumferential surface of the package and sucks a yarn end of the package.
  • the pipe part is connected to the suction port.
  • the wound yarn catch and guide device further includes a shaft part as a reference point when the suction port approaches the package.
  • the light passing part is provided in the pipe part.
  • a position at which a wound yarn passes through is likely to be assumed in the pipe part as compared with the suction port.
  • the light passing part is provided on the pipe part located on the suction port side relative to the shaft part and therefore the yarn end can be detected at an early stage. This can improve the efficiency of winding.
  • the inside of the pipe part has a guide portion for guiding a wound yarn sucked by the suction port to the detecting position.
  • the wound yarn is guided to the detecting position and therefore the accuracy of detection is improved. Particularly, even when the distance between a suction port and a package is changed, a wound yarn can be detected accurately.
  • the light passing part is a clear plate provided in at least a part of the pipe part.
  • the light passing part is a notch having a through hole provided in at least a part of the pipe part.
  • the detection part can directly detect a wound yarn within the move and catch part. This can improve the accuracy of detection.
  • the yarn pull-out device is configured as follows. That is, the suction port is a slit-like opening that extends parallel to a rotation axis direction of the package.
  • the pipe part includes a cylindrical portion and a connecting portion.
  • the cylindrical portion has an air passage having a circular cross-section.
  • the connecting portion is connected to the end of the cylindrical portion.
  • the cross-section shape of the cylindrical portion is changed from a circular shape to a slit shape in order to connect the cylindrical portion and the opening.
  • the light passing part is provided in the connecting portion side of the cylindrical portion.
  • a light passing part is provided at a position kept out of a connecting portion. This can improve the accuracy of detection. Moreover, the light passing part is provided on a side close to the suction port in the cylindrical portion. This can further shorten a detection time of a wound yarn.
  • the light passing part is provided at a circumferential surface of the cylindrical portion, the circumferential surface in a side opposed to the detection part when the wound yarn catch and guide device catches a wound yarn.
  • the light passing part is opposed to the detection part when the move and catch part moves to a catching position.
  • This can achieve a simple layout.
  • the light passing part is still opposed to the detection part even when the catching position of the move and catch part is slightly changed due to a package in a lump. This can detect a wound yarn without any troubles.
  • a reflection part which is located inside the cylindrical portion and reflects a emitted light, is provided in a side opposite to the light passing part across the detecting position.
  • the wound yarn is detected using the reflection light and thereby even colored wound yarn can be detected accurately.
  • the detection part is attached to the winding part.
  • a detection part is arranged in a winding part, and thereby the distance between the detection part and a package decreases. This can detect whether the wound yarn is caught by a move and catch part or not, at an early stage.
  • the yarn winding device is configured as follows. That is, the yarn winding device further includes a yarn feed part and a yarn joining device.
  • the yarn feed part has a yarn for being wound by the winding part.
  • the yarn joining device performs the yarn joining of a wound yarn and a yarn in the yarn feed part side when the yarn is disconnected between the winding part and the yarn feed part.
  • the yarn pull-out device guides the wound yarn to the yarn joining device.
  • a time required for the yarn joining can be shortened. Additionally, the minimum required wound yarn is sucked and then a yarn in a package-side is guided to a yarn joining device. This can minimize the amount of yarn which is cut and removed at a time of yarn joining.
  • the detection part is preferably attached to a metal part of the winding part.
  • the yarn winding device is configured as follows. That is, the winding part includes a support part, an auxiliary roller, a driving source, a traverse mechanism and a power transmission mechanism.
  • the support part rotatably supports a package.
  • the auxiliary roller assists the winding of yarn while coming in contact with the package and thereby the package is accordingly rotated.
  • the auxiliary roller is rotated by the driving source.
  • the traverse mechanism traverses a yarn.
  • the power transmission mechanism transmits driving force generated from the driving source to the package, in a state where the package is away from the auxiliary roller, and thereby the package is rotated.
  • a yarn of a package can be caught in a state where the package is away from the auxiliary roller, and therefore a yarn is not stuck to the package. This can reduce the probability of the failure of catching a yarn.
  • using a power transmission mechanism can achieve a configuration at the lower cost, as compared with a configuration provided a driving source separately.
  • a rotation speed of a package, a rotation direction and the like can be controlled by controlling the driving source.
  • the yarn joining method includes a catching step, a detecting step, a waiting step and a guiding step.
  • a sucking and catching operation in which the wound yarn catch and guide device approaches the package and then the package is rotated in the reverse direction from the winding direction in order to catch a wound yarn, is performed.
  • the wound yarn catch and guide device detects sucking and catching of the wound yarn.
  • the sucking and catching operation is continued until a setting time elapses from the detection of sucking and catching of the wound yarn.
  • the wound yarn is guided to the yarn joining device after the waiting step is completed.
  • the amount of the wound yarn appropriate for being guided to the yarn joining device can be sucked and caught. This can suppress the amount of yarn wasted at a time of yarn joining.
  • the yarn joining method further includes a yarn defect sucking and waiting step, which further waits until a yarn defect is sucked by the wound yarn catch and guide device after the waiting step.
  • the yarn defect sucking and waiting step for removing a yarn defect is further performed. This can prevent the yarn defect from remaining on a package.
  • FIG. 1 is a front elevational view showing a schematic configuration of an automatic winder 1 according to this embodiment.
  • an automatic winder (yarn winding device) 1 mainly includes a plurality of winding units 10 arranged side by side, a machine controller 12, and a doffing device 13.
  • the machine controller 12 can communicate with each of the plurality of winding units 10. An operator of the automatic winder 1 operates the machine controller 12 appropriately and thereby manages the plurality of winding units 10 collectively.
  • Each of the winding units 10 is configured to unwind a yarn 14 from a yarn feed bobbin 16, and wind on a wound bobbin 19 while traversing the yarn 14. In the above-described manner, the winding unit 10 forms a package 22.

  • a program for controlling each configuration of the winding units 10 is stored in the ROM.
  • the CPU executes the program stored in the ROM.
  • the winding unit 10 includes a yarn feed part 15 and a winding part 17.

  • the type of the yarn feed part 15 is not limited to a transport tray type. For example, a magazine type may be used.
  • the winding part 17 mainly includes a cradle (support part) 18, a wound bobbin 19 and a winding drum (auxiliary roller) 20.
  • the cradle 18 has a pair of a rotation support portions.
  • the cradle 18 can rotatably support the wound bobbin 19 (or a package 22) by tucking the wound bobbin 19 at the rotation support portion.
  • the cradle 18 is configured to switch between a state where a supported package 22 comes in contact with the winding drum 20 and a state where the package 22 is moved away from the winding drum 20.
  • the winding drum 20 traverses the yarn 14 onto a surface of the package 22, and also drives the package 22 to rotate.
  • the winding drum 20 is driven in rotation by a drum drive motor (driving source) 21.
  • the winding drum 20 is driven in rotation while being in contact with an outer circumference of the package 22, and thereby the package 22 can be accordingly rotated.
  • a traverse groove (traverse mechanism) having a spiral shape is provided in an outer circumferential surface of the winding drum 20.
  • the yarn 14 wound from a yarn feed bobbin 16 is wound on a surface of a package 22 while being traversed in a constant width by the traverse groove. This can form the package 22 having the constant winding width.
  • Other members arranged in the winding part 17 will be described later.
  • Each of the winding units 10 has an unwinding assist device 25, a tension applying device 27, a yarn joining device 38 and a clearer 40 arranged in this order from a yarn feed part 15 side, in a yarn travel path between the yarn feed part 15 and the winding part 17.
  • An upper yarn catch and guide device (wound yarn catch and guide device) 30 and a lower yarn catch and guide device 34 are arranged near the yarn joining device 38.
  • an upstream side and a downstream side with respect to a travel direction of the yarn 14 may be simply referred to as "upstream side” and "downstream side".
  • the unwinding assist device 25 includes a restricting member 26 that is able to overlie a core tube of a yarn feed bobbin 16.
  • the restricting member 26 having a substantially cylindrical shape is arranged so as to come in contact with a balloon, which is formed at an upper portion of a yarn layer of the yarn feed bobbin 16.
  • the balloon is a portion where the yarn 14 unwound from the yarn feed bobbin 16 is thrown around by the centrifugal force.
  • the restricting member 26 is brought into contact with the balloon, and therefore the yarn 14 comes in contact with the balloon of the yarn 14. This can prevent the yarn 14 from being excessively thrown around.
  • the yarn 14 can be unwound from the yarn feed bobbin 16 appropriately.
  • the tension applying device 27 applies a predetermined tension to the yarn 14 that is traveling.
  • the tension applying device 27 is configured as a gate type in which a movable comb is arranged relative to a fixed comb. The movable comb is driven such that the combs are brought into an engaged state with each other. The yarn 14 passes while being bent between the combs having the engaged state, so that an appropriate tension is applied to the yarn 14. This can improve the quality of a package 22.
  • the tension applying device 27 is not limited to the above-described gate type. For example, a disk type tension applying device can also be used.
  • the yarn joining device 38 performs yarn joining between the yarn 14 (lower yarn) in a yarn feed part 15 side and the yarn 14 (upper yarn, wound yarn) in a winding part 17 side when the yarn 14 is disconnected between the yarn feed part 15 and the winding part 17 for some reason.

  • the upper yarn catch and guide device 30 is connected to a negative pressure source (not shown), and generates suction stream in the suction port 33.

That is, when the light receiving part 68b receives light having the predetermined intensity or more, the detection part 68 determines that the yarn 14 is present (the yarn 14 is caught by a move and catch part 30a successfully).

  • the light passing part 69 is provided on the side close to the suction port 33 of the cylindrical portion 32a. This can reduce time until the yarn 14 is detected. Since the connecting portion 32b has a wide width, the position where the yarn 14 passes through depends on the portion where the suction port 33 catches the yarn 14. Therefore, the light passing part 69 is provided at the position behind the connecting portion 32b, and thereby reduction of the accuracy of detection of the yarn 14 can be prevented.
  • the light passing part 69 is opposed to the detection part 68 when the suction port 33 is located at the catching position. This can achieve a natural and simple layout. The light passing part 69 is still opposed to the detection part 68 even when the catching position of the suction port 33 is changed slightly due to the package 22 being in a lump. This can detect the yarn 14 without any troubles.

  • the first guide portion 321 is provided near an inner edge of a side farther from the suction port 33 (a side opposite to the light passing part 69). The first guide portion 321 sucks the yarn 14 sucked by the suction port 33 and guides to the second guide portion 322.
  • the second guide portion 322 is provided in a side near the suction port 33 (near the light passing part 69). A recess is formed in the second guide portion 322 and thereby guides the yarn 14. This can improve the accuracy of detection of the yarn 14.
  • the positional relationship between the detection part 68 and the light passing part 69 is adjusted such that at least a part of the detection part 68 penetrates the light passing part 69 when the suction port 33 catches a yarn of the package 22 (see Fig. 8 (a) ). Accordingly, success or failure in catching the yarn 14 can be determined at the position near the suction port 33. As described above, in a case that such as a transparent plate is arranged in a notch, the yarn 14 can be detected with the sufficient accuracy of detection.
  • Fig. 7 (a) shows a state during a winding operation by the winding part 17. At this time, the contact roller 64 does not come in contact with neither the wound bobbin 19 nor a winding drum 20.
  • the unit control section 50 winds the yarn 14 of the winding part 17 side into the package 22 and drives the cradle 18, and thereby the package 22 is moved away from the winding drum 20 (a state shown in Fig. 7 (b) ).
  • the unit control section 50 ejects air stream from the nozzle 62 of the air stream ejection part 60 toward the center portion in a winding shaft direction of the package 22. This can prevent cob-webbing.
  • the unit control section 50 allows the move and catch part 30a (the pipe part 32 and the suction port 33) to swirl from the waiting position to the catching position in order to catch the yarn 14 of the package 22 (S102, catching step).
  • the unit control section 50 drives the second link part 66 by a solenoid or the like, and thereby the contact roller 64 is moved in contact with the package 22 and the winding drum 20 (a state shown in Fig. 8 (a) ). Accordingly, driving force of the drum drive motor 21 can be transmitted to the package 22 via the winding drum 20 and the contact roller 64.
  • the contact roller 64 enables a reverse rotation of the package 22 without changing the rotation direction of the winding drum 20.
  • the contact roller 64 may come in contact after a rotation speed is reduced to some extent, in order to prevent damages of the package 22 and the winding drum 20.
  • the unit control section 50 generates suction stream in the suction port 33 that is located near the package 22 before and after a reverse rotation of the package 22. Accordingly, the suction port 33 can catch the yarn 14 of the package 22.
  • the package 22 is away from the winding drum 20. This can prevent the yarn 14 from sticking to the package 22, and improve the probability of catching of the yarn 14.
  • the suction port 33 is located between the package 22 and the winding drum 20, and thereby the yarn 14 can be surely caught. Moreover, in the suction port 33 of this embodiment, an edge portion located at the winding drum 20 side is extended. This can further improve the probability of catching of the yarn 14.
  • the move and catch part 30a approaches the detection part 68 by shifting to the catching position. Therefore, the yarn 14 caught by the suction port 33 is detected by the detection part 68 via the light passing part 69. This can check success or failure in catching the yarn 14 at an early stage.
  • the move and catch part 30a is shifted (moved) to the catching position, it is assumed that "the move and catch part 30a approaches the detection part 68" even in any state, where the move and catch part 30a is standing still before the detection part 68, the move and catch part 30a comes in contact with the detection part 68, and the detection part 68 is located within the move and catch part 30a.
  • the unit control section 50 determines whether the detection part 68 detects the yarn 14 or not (S103, detecting step).
  • the unit control section 50 performs a first waiting process (S104, waiting step) and a second waiting process (S105, yarn defect sucking and waiting step) when the detection part 68 detects the yarn 14.
  • the sucking and catching operation of the suction port 33 is continued during the first waiting process and the second waiting process.
  • the first waiting process is a process that continues to suck a predetermined amount of the yarn 14, in order to prevent being out of (being not enough) the yarn 14 when the yarn 14 is guided to the yarn joining device 38 by shifting the move and catch part 30a toward the lower side.
  • the second waiting process is a process that continues to suck a predetermined amount of the yarn 14, in order to remove a yarn defect detected by the clearer 40 after sucking (in order to prevent a yarn defect from remaining in the package 22).
  • the unit control section 50 releases a sucking and catching operation and guides the yarn 14 to the yarn joining device 38 after the first waiting process and the second waiting process (S106).
  • the unit control section 50 allows a lower yarn catch and guide device 34 to shift and catch a lower yarn, simultaneously with catching of an upper yarn, and guide it to the yarn joining device 38. After that, the yarn joining device 38 performs yarn joining between the upper yarn and the lower yarn, and thereby a winding operation is restarted (a state shown in Fig. 8 (b) ).
  • the contact roller 64 is preferably arranged at an end portion, not the center portion in a winding shaft direction, so as not to disturb catching of the yarn 14 by the suction port 33.
  • the contact roller 64 is arranged at an end portion (position A or position C) on a side opposite to the unit control section 50 among end portions in the winding shaft direction. Thereby, a space is formed around the contact roller 64 and the contact roller 64 is positioned at a near side. This can facilitate a mounting/dismounting operation of the contact roller 64.
  • the contact roller 64 can be arranged in a front side of the device or a back side of the device. In a case of arranging the contact roller 64 in the front side of the device (position A or position B), a space is formed around the contact roller 64 although catching of the yarn 14 by the suction port 33 is slightly disturbed. This can facilitate the mounting/dismounting operation of the contact roller 64. In a case that the contact roller 64 is arranged in the front side of the device, as shown in Fig. 8 (a) , the contact roller 64 comes in contact with the package 22 and the winding drum 20 such that the contact roller 64 is meshed with the package 22 and the winding drum 20. Therefore, the contact roller 64 surely comes in contact with the package 22 and the winding drum 20.
  • an optimum position is selected depending on such as the positional relationship of the winding part 17, the form of the suction port 33 and the like.
  • the above-described embodiment is a configuration having one contact roller 64, however, the first modification is a configuration having three contact rollers 64. Also in a configuration having three contact rollers 64, as shown in Fig. 11 , the contact rollers 64 enable a reverse rotation of the package 22 without changing a rotation direction of the winding drum 20. Therefore, the odd-number of the contact rollers 64 is preferable.
  • driving force of the drum drive motor 21 is transmitted to the package 22 by the contact roller 64.
  • driving force of the drum drive motor 21 is transmitted to the package 22 by a support part relaying power transmission mechanism (power transmission mechanism) 70 via the cradle 18 (in more detail, the rotation support portion).
  • a support part relaying power transmission mechanism 70 power transmission mechanism 70 via the cradle 18 (in more detail, the rotation support portion).
  • the support part relaying power transmission mechanism 70 includes a power transmission shaft 71, a belt 72, a power transmission shaft 73, a gear 74, a gear 75, a clutch 76 and a power transmission shaft 77.
  • the power transmission shaft 71 is a rotation shaft of the winding drum 20 and rotatable integrally with the winding drum 20. Driving force transmitted to the power transmission shaft 71 is transmitted to the power transmission shaft 73 via the belt 72.
  • the power transmission shaft 71 and the power transmission shaft 73 have same rotation direction due to the transmission via the belt 72.
  • Driving force transmitted to the power transmission shaft 73 is transmitted to the clutch 76 via the gear 74 mounted to the power transmission shaft 73 and the gear 75 meshes with the gear 74.
  • the power transmission shaft 73 rotates in a reverse direction relative to the power transmission shaft 71 or the like because the gear 75 meshes with the gear 74.
  • the clutch 76 can switch between a state where the transmitted driving force is transmitted to the power transmission shaft 77 and a state where the transmitted driving force is not transmitted to the power transmission shaft 77.
  • the power transmission shaft 77 is configured to rotate integrally with a rotation support portion for rotatably supporting the package 22.
  • the power transmission shaft 77 rotates in the same direction as the gear 75 (in a reverse direction relative to the power transmission shaft 71), and thereby the package 22 is rotated in a reverse direction relative to the winding drum 20.
  • a support part relaying power transmission mechanism 70 of the second modification is merely illustrative, and there are appropriately changeable components.
  • the above-described yarn pull-out device 28 includes an upper yarn catch and guide device 30 and a detection part 68.
  • the upper yarn catch and guide device 30 has a move and catch part 30a that moves from a waiting position to a catching positon in the winding part 17 side, sucks and catches a wound yarn of a yarn in the winding part 17 side.
  • the detection part 68 detects a wound yarn caught by the upper yarn catch and guide device 30.
  • the move and catch part 30a approaches the detection part 68 by moving from the waiting position to the catching position (that is, the detection part 68 is provided in a position other than the position of the move and catch part 30a).
  • the detection part 68 detects the presence or absence of the wound yarn within the move and catch part 30a moved to the catching position.
  • a burden is not put onto wiring connected to the detection part 68 since the detection part 68 is arranged in a position that differs from the move and catch part 30a. Moreover, a wound yarn can be detected at a position near a suction port 33 of the move and catch part 30a because consideration for a burden on wiring is unnecessary. This can reduce time of yarn joining.
  • the winding part 17 of an automatic winder (yarn winding device) 1 of this embodiment includes a cradle (supporting part) 18, a winding drum (auxiliary roller) 20, a drum drive motor (driving source) 21, a traverse groove (traverse mechanism) of the winding drum 20 and a power transmission mechanism (a contact roller 64 or a support part relaying power transmission mechanism 70).
  • the cradle 18 rotatably supports the package 22.

  • the yarn 14 does not stick to the package 22 since the yarn 14 of the package 22 can be caught in a state where the package 22 is away from the winding drum 20. This can reduce the probability of failure in catching the yarn 14.
