Description

The present invention relates to a take-up winder equipped with a take-up winder for taking up a spun yarn.

BACKGROUND ART Patent Document 1 discloses a take-up winder that takes up a plurality of yarns spun from a spinning machine (spinning device) and winds them onto a rotating bobbin. A plurality of yarns spun from a spinning device are taken up by a plurality of godet rollers provided in a take-up winder, distributed to a plurality of fulcrum guides, and traversed by a plurality of traverse guides to form a plurality of bobbins. (winding process).

Before starting the winding process, it is necessary to carry out a yarn threading operation for threading each part of the take-up winder. As a rough procedure, it is necessary to hook the yarn to the godet roller and the fulcrum guide while sucking and holding the yarn with a suction gun. In addition, it is necessary to hook the yarn onto the rotating bobbin and cause the traverse guide to catch the yarn and initiate traversing.

Here, if the winding process is started in a state where the yarn hooking operation fails (for example, the yarn is not hooked at a predetermined position), a winding failure occurs. Generally, in the above-described take-up winder, if a winding failure occurs on a certain bobbin, the yarn wound on all the remaining bobbins must also be discarded, resulting in a large loss. Therefore, it is conceivable to use a yarn breakage detection device (yarn detection unit) as described in Patent Documents 2 and 3 in order to detect failure of yarn hooking. The yarn detecting portion described in Patent Document 2 can detect whether or not the yarn is traversed normally. Further, the yarn detecting section described in Patent Document 3 is attached to the tip of the suction gun and can detect whether or not the yarn is normally sucked and held.

In the case of using the yarn detecting section described in Patent Document 2, for example, it is conceivable to detect failure of yarn hooking depending on whether or not traversing is normally performed after yarn hooking work is completed. However, in such a method, the winding process is stopped after the yarn has been wound to some extent on other bobbins that have been successfully threaded. In this case, an operation such as removing the yarn wound on the bobbin is required, which may also result in a large production loss. Further, in the thread detection section described in Patent Document 3, when it is necessary to thread a plurality of threads, even if one of the plurality of threads to be sucked and held by the suction gun is broken, the other threads are still working properly. thread breakage cannot be detected if it is held by suction.

Each spinning device 2 is configured to spin a plurality of yarns Y made of synthetic fibers. A plurality of take-up winders 3 are arranged in the left-right direction, each takes up the yarn Y spun from the spinning device 2 arranged above, and winds it around a plurality of bobbins B to form a package P. process. The general control device 4 centrally controls the plurality of take-up winders 3 .

(Spinning winder)
As shown in FIGS. 1 and 2, the take-up winder 3 includes a first godet roller 12 (take-up roller of the present invention), a second godet roller 13 (yarn feed roller of the present invention), a take-up device 14, and a winding control device 15 (control unit of the present invention; see FIG. 3). The first godet roller 12 is a roller whose axial direction is substantially parallel to the left-right direction, and is arranged above the front end portion of the winding device 14 . The first godet roller 12 is rotationally driven by a motor (not shown). The second godet roller 13 is a roller whose axial direction is substantially parallel to the left-right direction, and is arranged above and behind the first godet roller 12 . The second godet roller 13 is rotationally driven by a motor (not shown).

The second godet roller 13 is movably supported by the guide rail 16 . The guide rail 16 obliquely extends upward and rearward. The second godet roller 13 is configured to be movable along the guide rail 16 by, for example, a moving motor 111 (see FIG. 3), a pair of pulleys and a belt (not shown). As a result, the second godet roller 13 is placed in the winding position (see the solid line in FIG. 1) when the winding process is performed, and in the vicinity of the first godet roller 12 when the thread hooking operation, which will be described later, is performed. and the thread hooking position (see the dashed line in FIG. 1).

The cutting and holding part 11 is configured to temporarily hold the yarn Y before the yarn hooking operation. The cutting/holding unit 11 has a cutter 11a that cuts the yarn Y and an aspirator 11b that holds the yarn Y by suction. The cutter 11a and the aspirator 11b are configured to move forward and backward in the left-right direction, and are movable between a retracted position and a holding position for cutting and holding the yarn Y on the right side of the retracted position.

The winding device 14 is configured to wind a plurality of yarns Y onto a plurality of bobbins B to form a package P. As shown in FIG. The winding device 14 is arranged below the first godet roller 12 and the second godet roller 13 . The winding device 14 includes a plurality of fulcrum guides 21, a plurality of traverse guides 22, a turret 23, two bobbin holders 24, a contact roller 25, and a yarn detector 26 (traverse detector of the present invention). Prepare.

The plurality of fulcrum guides 21 serve as fulcrums when the yarn Y is traversed by each traverse guide 22 . A plurality of fulcrum guides 21 are provided individually for a plurality of yarns Y and arranged in the front-rear direction. The plurality of fulcrum guides 21 are connected to each other by, for example, a belt (not shown) and driven to move by an air cylinder 112 (see FIG. 3). The supply of compressed air to the air cylinder 112 and the discharge of compressed air from the air cylinder 112 are performed by controlling an electromagnetic valve (not shown) by the winding control device 15 (see FIG. 3) (other air The same applies to cylinders). As a result, the plurality of fulcrum guides 21 are arranged to be spaced apart from each other in the front-rear direction (see FIG. 1) when the yarn Y is wound, and to be gathered at the front side when the yarn is hooked. position (see FIG. 4).

The plurality of traverse guides 22 are individually provided for the plurality of yarns Y and arranged side by side in the front-rear direction. The traverse guide 22 is, for example, a known blade-type traverse guide, and has two blade guides 22a (see FIG. 7) that rotate in opposite directions. The blade guide 22a is driven by, for example, a traverse motor 113 (see FIG. 3). As a result, the yarn Y is traversed in the front-rear direction by the blade guide 22a with the fulcrum guide 21 as the fulcrum.

The turret 23 is a disc-shaped member whose axial direction is substantially parallel to the front-rear direction. The turret 23 is rotationally driven by a turret motor 114 (see FIG. 3). The two bobbin holders 24 each have an axial direction parallel to the front-rear direction, and are rotatably supported by the upper and lower ends of the turret 23 . A plurality of bobbins B individually provided for a plurality of yarns Y are mounted on each bobbin holder 24 side by side in the front-rear direction (bobbin axial direction) and rotatably supported. The two bobbin holders 24 are rotationally driven by individual winding motors 115 (see FIG. 3).

The contact roller 25 is a roller whose axial direction is substantially parallel to the front-rear direction, and is arranged immediately above the upper bobbin holder 24 . The contact roller 25 contacts the surfaces of the packages P supported by the bobbin holder 24 on the upper side to apply contact pressure to the surfaces of the packages P being wound, thereby shaping the packages P. As shown in FIG. The contact roller 25 is configured to be vertically movable by, for example, a moving mechanism (not shown). Alternatively, the contact roller 25 may be configured to be swingable with the front-rear direction as the swing axis direction.

The yarn detector 26 is arranged between the fulcrum guide 21 and the traverse guide 22 in the yarn running direction. In other words, the yarn detector 26 is arranged downstream of the second godet roller in the yarn running direction. The yarn detecting section 26 is composed of, for example, a plurality of reflective optical sensors each having a light emitting section 26a and a light receiving section 26b (see FIG. 2). The light emitting portion 26a and the light receiving portion 26b are arranged on the left side of the yarn Y, for example. The optical sensor is configured such that light is emitted from the light emitting portion 26a and light reflected by the yarn Y is received by the light receiving portion 26b. The optical sensor transmits information about the amount of light detected by the light receiving section 26b to the winding control device 15 (see FIG. 3). The thread detection section 26 may have a transmissive optical sensor instead of the reflective optical sensor. That is, the light-emitting portion 26a and the light-receiving portion 26b may be arranged so as to face each other with the yarn Y sandwiched therebetween in the left-right direction.

The take-up control device 15 has a CPU, a ROM, a RAM, etc., and controls each part of the take-up winder 3 such as the moving motor 111 (see FIG. 3). The take-up control device 15 also has an operation unit 121 (see FIG. 3) operated by the operator, and a notification unit 122 (see FIG. 3) for informing the operator of information. The operation unit 121 has, for example, operation buttons (not shown). The notification unit 122 has, for example, an alarm lamp (not shown). The take-up control device 15 is electrically connected to the general control device 4 (see FIG. 3) and communicates with the general control device 4 .

In the winding device 14 having the above configuration, when the upper bobbin holder 24 is driven to rotate, the yarn Y traversed by the traverse guide 22 is wound around the bobbin B to form the package P (winding process). Further, when the package P is fully wound, the upper and lower positions of the two bobbin holders 24 are exchanged by rotating the turret 23 . As a result, the bobbin holder 24 positioned on the lower side moves upward, and the package P can be formed by winding the yarn Y around the bobbin B attached to the bobbin holder 24 . Also, the bobbin holder 24 with the fully wound package P attached thereto moves downward, and the package P is recovered by, for example, a package recovery device (not shown).

During the winding process, the winding control device 15 determines whether or not each yarn Y is traversed normally based on the information received from the yarn detection section 26 . When it is determined that all the yarns Y are traversed normally, the winding control device 15 controls the take-up winder 3 to continue the winding process. If it is determined that any one of the plurality of yarns Y is not traversed normally, for example, the winding control device 15 controls the cutting and holding unit 11 to cut the plurality of yarns Y, and the spinning winder 3 to stop the winding process. The cut yarn Y is temporarily held by the cut holding section 11 .

(Configuration for threading work)
Next, an example of a configuration for performing a yarn hooking operation in the take-up winder 3 will be described with reference to FIGS. 3 to 7. FIG.

The yarn convergence guide 31 is configured to converge a plurality of traveling yarns Y to the front end portion of the take-up winder 3 during the yarn hooking operation. The first separator 32 temporarily holds a plurality of threads Y respectively hung on the plurality of fulcrum guides 21 . The second separator 33 receives the yarn Y from the first separator 32 and performs operations such as moving the yarn Y to a position where the yarn Y can be caught by the traverse guide 22 . By temporarily removing the traversed yarn Y from the traverse guide 22, the yarn pulling device 34 guides the yarn Y to the slit S (see FIG. 7) formed at the end of the bobbin B in the bobbin axial direction. is configured to

The yarn convergence guide 31 is arranged at the front end of the take-up winder 3 . As shown in FIG. 5, the yarn convergence guide 31 is attached to the tip of an arm-shaped swinging member 36 that can swing with the front-rear direction as the swinging axis direction. The swinging member 36 is swingably driven by, for example, an air cylinder 116 (see FIG. 3). As a result, the yarn convergence guide 31 can be moved between the initial position (see the solid line in FIG. 5) located at the right end of the take-up winder 3 and the delivery position (see the two-dot chain line in FIG. 5) to the left of the initial position.

As shown in FIGS. 6A and 6B, the holding member 42 has a body portion 42a and a protrusion 42b projecting rearward from the end of the body portion 42a opposite to the guide member. The plurality of holding members 42 are connected to each other by, for example, belts (not shown), and driven to move in the front-rear direction by an air cylinder 118 (see FIG. 3). Specifically, the plurality of holding members 42 are arranged at a first position (see FIG. 6A) in which the pitch in the front-rear direction is substantially equal to the pitch in the front-rear direction of the plurality of bobbins B, and at the front side of the first position. It is movable between the assembled second position (see FIG. 6(b)). Note that the holding member 42 may be driven by a drive unit such as a motor (not shown) instead of the air cylinder 118 .

The second separator 33 is arranged to the left of the first separator 32 . The second separator 33 has an arm-shaped swinging member 46 that extends in the front-rear direction and can swing around the front-rear direction as a swing axis, and a holding member 47 that is fixed to the tip of the swinging member 46 . At the end of the holding member 47 opposite to the swinging member 46, for example, as shown in FIG. It is A protrusion 47b protruding rearward from the front end of the inlet of each insertion space 47a and a protrusion 47c protruding forward from the rear end of the inlet are provided so as to face each other with a gap in the front-rear direction. ing. The pitch of the insertion spaces 47a in the front-rear direction is substantially equal to the pitch of the plurality of bobbins B in the front-rear direction. The swinging member 46 and the holding member 47 are swingably driven by, for example, an air cylinder 119 (see FIG. 3). As a result, the swinging member 46 and the holding member 47 are moved from the first separator 32 to the retracted position where they do not overlap the turret 23 when viewed in the front-rear direction, and the first separator 32 which partially overlaps the turret 23 when viewed in the front-rear direction. It is movable to and from a receiving position for receiving Y (see FIG. 5).

(see two-dot chain line).

(Procedure of threading work and detection method of threading failure)
Next, an example of the yarn hooking operation procedure in the take-up winder 3 and a yarn hooking failure detection method will be described with reference to the flowchart of FIG. 8 and the explanatory diagrams of FIGS. 9 to 16. FIG. In this embodiment, a part of the threading work is performed by the operator, and a part of the threading work is performed by the threading execution section 30 . In the present embodiment, the failure of the threading operation is detected as described later in order to reduce production loss when the threading operation fails.

As a state (initial state) of the spinning winder 3 before the yarn threading operation is performed, a plurality of yarns Y spun from the spinning device 2 are sucked and held by the aspirator 11b (see FIG. 4). Further, the second godet roller 13 and the plurality of fulcrum guides 21 are positioned at the positions during the yarn hooking operation (see FIG. 4). Traverse guide 22 and bobbin holder 24 are stopped. The thread detection section 26 is in the OFF state. The yarn convergence guide 31 is located at the initial position (see the solid line in FIG. 5). The guide member 41 of the first separator 32 is located at the initial position (see FIG. 5). The plurality of holding members 42 of the first separator 32 are positioned at the second position (see FIG. 6(b)). The swing member 46 and the holding member 47 of the second separator 33 are positioned at the retracted position (see the solid line in FIG. 5). The holding member 52 of the thread pulling device 34 is positioned at the retracted position (see the solid line in FIG. 7).

First, the operator threads the first godet roller 12, the second godet roller 13 and the fulcrum guides 21 as shown in FIGS. 9(a) to 9(c). Specifically, the operator operates a known suction gun 60 capable of sucking and holding the yarn Y to take up the yarn Y sucked and held by the aspirator 11b. Subsequently, the operator applies the yarn Y sucked and held by the suction gun 60 to the first godet roller 12 and the second godet roller 13 in this order (S101; see FIGS. 9A and 9B). Further, the operator uses a thread hooking jig (not shown) to hook the plurality of threads Y to the plurality of fulcrum guides 21 (S102; see FIG. 9C). The above work is mainly performed in the front space (work space) of the take-up winder 3 .

Next, the operator operates the operation unit 121 to move the second godet roller 13 and the fulcrum guide 21 to the positions for the winding process. Along with this, the winding control device 15 controls the yarn hooking execution unit 30 to start the yarn hooking operation. First, the take-up control device 15 controls the moving motor 111 and the air cylinder 112 (strictly speaking, an electromagnetic valve (not shown); hereinafter the same applies to other air cylinders) so that the second godet roller 13 and the fulcrum guide 21 to the position for the winding process (see FIG. 10). Next, the operator operates the suction gun 60 to hang the yarn Y on the yarn convergence guide 31 (see FIG. 10). As a result, a plurality of threads Y are arranged immediately behind the corresponding holding members 42 of the first separator 32 (see FIG. 12(a)).

Next, the winding control device 15 controls the air cylinder 119 (see FIG. 3) to move the swinging member 46 and the holding member 47 of the second separator 33 from the retracted position (see the two-dot chain line in FIG. 11) to the receiving position. (See the solid line in FIG. 11). As a result, the holding member 47 moves to the vicinity of the second separator 33 (see FIG. 12(b)). The winding control device 15 appropriately controls the turret motor 114 during the yarn hooking operation to position the bobbin holder 24 at a position where it does not interfere with the second separator 33 . Substantially simultaneously with the start of the operation of the second separator 33 or after the start of the operation of the second separator 33, the winding control device 15 controls the air cylinder 118 (see FIG. 3) to The holding member 42 of 32 is moved from the second position to the first position (see FIG. 12(b)). As a result, the thread is temporarily hung on each holding member 42 (S103). The projection 42b prevents the yarn Y from falling off from the holding member 42 (see FIG. 12(b)). Along with controlling the air cylinder 118 , the winding control device 15 controls the winding motor 115 to start rotating one of the two bobbin holders 24 . At the same time as the bobbin holder starts rotating, the traverse guide 22 also starts operating.

Next, the winding control device 15 causes the yarn hooking execution unit 30 to transfer the yarn Y from the first separator 32 to the second separator 33 (S104). Specifically, the winding control device 15 controls the air cylinder 117 to move the guide member 41 of the first separator 32 leftward (see the two-dot chain line arrow in FIG. 13(a)). As a result, the plurality of yarns Y move to the immediate right side of the holding member 47 of the second separator 33, and each yarn Y enters the corresponding insertion space 47a of the second separator 33 (see FIG. 14(a)). Next, the winding control device 15 controls the air cylinder 116 to move the yarn convergence guide 31 to the delivery position (see FIG. 13(b)). Further, the winding control device 15 controls the air cylinder 117 (see FIG. 3) to move the holding member 42 of the first separator 32 from the first position to the second position again. As a result, the yarn Y is transferred from the holding member 42 of the first separator 32 to the holding member 47 of the second separator 33 (see FIG. 14(b)). The yarn Y is prevented from falling off from the holding member 47 by the projections 47b and 47c.

Next, the take-up control device 15 causes the yarn hooking execution unit 30 to hook the yarn to the traverse guide 22 (S105). Specifically, the winding control device 15 controls the air cylinder 119 to swing the swinging member 46 and the holding member 47 of the second separator 33 leftward from the receiving position. As a result, the yarn Y is caught and traversed by the traverse guide 22 in operation.

In this state, the winding control device 15 turns on the yarn detection section 26 (S106), and determines whether or not the yarn Y is traversed normally based on the information from the yarn detection section 26 (S107). . Thereby, the winding control device 15 determines whether or not the yarn hooking operation has failed. The winding control device 15 continues the yarn hooking operation only when it determines that all the yarn Y has been detected normally (S107: Yes), that is, when it determines that the yarn hooking operation has not failed. That is, the winding control device 15 temporarily turns off the yarn detection unit 26 (S108), and causes the yarn pulling device 34 to thread the bobbin B (S109). Specifically, the winding control device 15 controls the turret motor 114 to move the rotating bobbin holder 24 upward (see FIG. 16). Further, the winding control device 15 controls the air cylinder 120 to move the holding member 52 of the yarn pulling device 34 to the catching position (see FIG. 17(a)). As a result, the traversed yarn Y is caught by the holding member 52 and temporarily removed from the traverse guide 22 . At this time, the yarn Y is not traversed by the traverse guide 22, but the yarn detector 26 is temporarily turned off as described above. will not be judged based on Subsequently, the yarn Y is passed through the slit S of the rotating bobbin B and bunched (not shown). A portion of the yarn Y downstream of the bobbin B in the yarn running direction is cut when the tension of the yarn Y increases. Further, the take-up control device 15 causes the holding member 52 to return to the captured position. As a result, tail winding is performed between the slit S of the bobbin B and the front end of the traverse region T (not shown). Thereafter, when the yarn Y is caught by the traverse guide 22, the holding member 52 moves to the retracted position. As described above, the threading operation is completed, and the winding process can be started. Note that when the winding process is started, the winding control device 15 turns on the yarn detection section 26 again.

On the other hand, if it is determined that any one of the plurality of yarns Y is not traversing normally (S107: No), the winding control device 15 causes the cutter 11a of the cutting/holding section 11 to cut all the yarns Y. (S110), the aspirator 11b is made to suck and capture. The remaining yarn generated by cutting the yarn Y is sucked by the suction gun 60 and then discarded. Further, the take-up control device 15 controls each part of the take-up winder 3 to restore the state of the take-up winder 3 to the initial state described above (S111). In parallel with the return operation to the initial state, or after the return operation is completed, the winding control device 15 causes the notification unit 122 to notify the operator (S112). As a result, the operator can smoothly restart the threading operation. At this time, since the yarn Y has not yet been wound around the bobbin B, there is no need to remove the yarn from the bobbin B.

As described above, during the threading operation, it is determined whether or not the threading operation has failed before the plurality of yarns Y are respectively wound on the plurality of bobbins B. As a result, the yarn hooking operation can be redone before the process of winding the yarn Y onto the bobbin B is started. Therefore, it is possible to avoid the need to remove the yarn from the bobbin B even if the yarn hooking operation fails. Therefore, in the take-up winder 3 that winds a plurality of yarns Y, it is possible to suppress production loss when the yarn hooking operation fails.

In addition, on the downstream side of the second godet roller 13 in the yarn traveling direction, the plurality of yarns Y are arranged at positions far from the working space by the fulcrum guide 21, and for other reasons, the operator may be concerned about failure of the yarn hooking operation. Visual detection can be difficult. In such a configuration, it is effective that the yarn detector 26 is arranged downstream of the second godet roller 13 in the yarn traveling direction.

During the winding process, the winding control device 15 also determines whether or not the winding process is normally performed based on the detection result of the yarn detection section 26 . In other words, it is possible to determine whether or not the yarn hooking operation has failed and whether or not the winding process has been performed normally based on the same detection result by the yarn detection section 26 . Therefore, compared with the case where it is necessary to provide different detection units for making the above two kinds of determinations, it is possible to suppress an increase in cost.

Further, the winding control device 15 determines whether or not each yarn Y is traversed by each traverse guide 22 based on the detection result of the yarn detecting section 26 when the yarn hooking operation is being performed, thereby determining whether each yarn Y is being traversed by each traverse guide 22 or not. Determine whether or not there is a failure in the work in progress. In general, it is easier and more reliable to detect the presence or absence of the yarn Y being traversed than to detect the presence or absence of the yarn Y traveling straight. Therefore, by using the yarn detecting section 26 for detecting the traversing, it is possible to easily and reliably determine whether or not the yarn hooking operation has failed.

Further, the winding control device 15 controls the yarn pulling device 34 to hang the plurality of yarns Y on the plurality of bobbins B only when it is determined that the yarn hooking operation has not failed. As a result, it is possible to reliably avoid starting the winding process for the other yarn Y when the yarn hooking operation fails for a certain yarn Y. Therefore, production loss can be reliably suppressed.

Further, when the winding control device 15 determines that the threading operation has failed, it causes the notification unit 122 to notify the operator. As a result, when a threading operation fails, the operator can quickly redo the threading operation.

In addition, when the yarn hooking operation fails, the plurality of yarns can be cut and temporarily held by the cutting/holding portion 11 . As a result, the threading operation can be started again smoothly.

Further, in a configuration in which a part of the threading work is executed by the threading execution unit 30, the operator is not always near the spinning winder 3 where the threading work is being performed, and the operator is not always present. Confirmation may not always occur. In such a configuration, it is particularly effective to be able to detect a failure in the thread hooking operation based on the detection result of the thread detection section 26.

Further, when the winding control device 15 determines that the yarn hooking operation has failed, the winding control device 15 controls the yarn hooking execution unit 30 to restore the state of the spinning winder 3 to the initial state for redoing the yarn hooking operation. return. As a result, the yarn threading operation can be redone more smoothly than in the case where the operator needs to take action to restore the state of the take-up winder 3 to the initial state. Therefore, production loss can be suppressed more effectively.

Next, a modification in which the above embodiment is modified will be described. However, components having the same configurations as those of the above-described embodiment are denoted by the same reference numerals, and description thereof will be omitted as appropriate.

(1) In the above embodiment, a part of the yarn threading work is performed by the operator, but it is not limited to this. For example, as shown in FIG. 18, the take-up winding facility 1a may include a yarn threading robot 5 that performs threading instead of the operator. The yarn hooking robot 5 is suspended, for example, from a rail member 70 extending in the left-right direction, and is configured to be movable in the front-side space of the plurality of take-up winders 3 along the rail member 70 in the left-right direction. The yarn threading robot 5 is electrically connected to the general control device 4 (see FIG. 3), and communicates with the general control device 4 . The yarn hooking robot 5 includes a body portion 71 , a robot arm 72 and a yarn hooking unit 73 . The robot arm 72 is attached to, for example, the lower surface of the body portion 71 . The robot arm 72 has a plurality of arms 72a and a plurality of joints 72b connecting the arms 72a. Each joint portion 72b incorporates an arm motor (not shown). When the arm motor is driven, the arm 72a swings about the joint portion 72b. The yarn hooking unit 73 is attached to the tip of the robot arm 72 . The yarn hooking unit 73 has a suction (not shown) or the like, and is configured to be able to hold the yarn Y temporarily. 19(a) and 19(b), the yarn hooking robot 5 hooks the yarn Y to the first godet roller 12 and the second godet roller 13, and further to a plurality of fulcrum guides 21 and the like. Thread Y may be hung. In this way, all the threading operations may be performed without human intervention. In this case, the threading robot 5 is also included in the threading execution unit of the present invention.

In such a take-up winder 1a, when the take-up control device 15 of a certain take-up winder 3 determines that a failure has occurred during the take-up work, the yarn take-up winder 3 is instructed to A signal may be output to instruct the threading robot 5 to re-execute the threading work. Then, based on the signal received from the winding control device 15, the integrated control device 4 may send a signal to the threading robot 5 to instruct the threading operation to be re-executed. By doing so, the threading operation can be redone more smoothly. Further, in the case where the yarn hooking operation fails in this configuration, the winding control device 15 does not necessarily have to cause the notification unit 122 to notify the operator.

(2) The configuration of the yarn threading executing section 30 is not limited to that described above. That is, it is sufficient that the yarn Y is in a state in which it can be detected by the yarn detection unit 26 before the yarn Y is wound on the bobbin B during the yarn hooking operation. It is sufficient that Y can be operated.

(3) In the above-described embodiments, the winding control device 15 also utilizes the yarn detecting section 26 for detecting the yarn Y traversed by the traverse guide 22 during the winding process during the yarn hooking operation. Although it is determined whether or not there is a failure in the threading operation, the present invention is not limited to this. For example, a traverse detection sensor (not shown) for detecting the yarn Y being traversed during the yarn hooking operation may be provided separately from the yarn detection section 26 . Then, the take-up control device 15 may use the traverse detection sensor only during the threading operation, and determine whether or not the threading operation has failed based on the detection result. In this case, the traverse detection sensor corresponds to the yarn detection section and the traverse detection section of the present invention. Alternatively, for example, a yarn running detection sensor (not shown) for detecting the presence or absence of the yarn Y running straight may be provided separately from the yarn detection section 26 . In this case, the yarn running detection sensor corresponds to the yarn detection section of the present invention. The yarn running detection sensor may be arranged downstream of the second godet roller 13 in the yarn running direction, or may be arranged upstream of the second godet roller 13 in the yarn running direction. The yarn running detection sensor may be used only during the yarn hooking operation, or may also be used during the winding process.

Alternatively, a camera (not shown) may be provided as the thread detection section instead of the sensor described above. For example, one camera may be provided for one take-up winder 3 . Alternatively, the same number of cameras as the number of yarns Y may be provided. The camera may be provided, for example, upstream of the winding device 14 (that is, of the plurality of fulcrum guides 21) in the yarn running direction. Alternatively, the camera may be provided in the threading robot 5 described in the modified example (1). For example, a camera may be provided at the suction of the yarn hooking unit 73 of the yarn hooking robot 5 .

(4) In the above-described embodiments, when the winding control device 15 determines that the yarn threading operation has failed, the yarn threading execution unit 30 is controlled to restore the state of the spinning winder 3 to the initial state. Although it is supposed to be returned, it is not limited to this. The winding control device 15 may, for example, control the cutting and holding unit 11 to cut, suck and hold the plurality of yarns Y, and then simply cause the notification unit 122 to notify the operator. In this case, when the operator operates the operation unit 121, the winding control device 15 may control the yarn hooking execution unit 30 to restore the state of the take-up winder 3 to the initial state.

(5) In the above-described embodiments, the winding control device 15 controls the cutting/holding unit 11 to cut, suck and hold a plurality of yarns Y when it is determined that the yarn hooking operation has failed. However, it is not limited to this. The take-up control device 15 may, for example, simply interrupt the threading operation and then cause the notification unit 122 to notify the operator. In this case, the take-up control device 15 may operate the cutting/holding unit 11 when the operator operates the operating unit 121 .

(6) In the above-described embodiments, the winding control device 15 continues the threading work only when it is determined that the threading work has not failed, but the present invention is not limited to this. . For example, even if the winding control device 15 determines that the threading work has failed, the winding control device 15 continues the threading work and, for example, causes the notification unit 122 to notify the worker. may be prompted to take prompt action. In this case, the operator may operate the operation section 121 so that the winding control device 15 stops the threading operation.

(7) In the above embodiments, the take-up control device 15 is provided to control the take-up winder 3, but the present invention is not limited to this. For example, the integrated control device 4 may control a plurality of take-up winders 3 .

(8) In the above-described embodiments, the take-up winding equipment 1 is provided with a plurality of take-up winders 3, but the invention is not limited to this. Only one spinning winder 3 may be provided.
