  In the conventional yarn splicing carriage, the second catching and guiding device is operated by a cam mechanism that is operated by one drive source. Therefore, in the conventional yarn splicing carriage, the operation of the second catching and guiding device is included in a series of operations of the cam mechanism. Therefore, in the conventional yarn splicing carriage, the second catching and guiding device can only perform a uniform operation, and therefore cannot operate in accordance with the package state (diameter size, etc.). There wasn't. In addition, the conventional yarn splicing cart cannot perform a retry operation depending on the situation.

  The present invention provides a spinning machine capable of improving the efficiency of yarn splicing operation.

  A spinning machine according to one aspect of the present invention includes a plurality of spinning units, a carriage that travels in an arrangement direction of the plurality of spinning units, and a control unit that controls the operation of the carriage. A spinning device that twists the bundle to produce a yarn; and a winding device that winds the yarn produced by the spinning device to form a package; and the carriage has a first yarn on the spinning device side, A yarn joining device for joining a second yarn drawn out from a package of the winding device, a first yarn catching position for catching the first yarn and catching the first yarn, and a yarn joining device for the first yarn A first catching and guiding device movable to a first yarn guiding position for guiding the second yarn, a second yarn catching position for catching the second yarn, and a second yarn catching device for guiding the second yarn to the yarn joining device. A second catching and guiding device movable to a two-thread guide position and a first catching and guiding device; A first drive dedicated to the first catching and guiding device that moves to the position and the first yarn guiding position, and a second catching and guiding device that moves the second catching and guiding device to the second and second yarn catching positions. And a dedicated second driving unit.

  In the spinning machine according to one aspect of the present invention, the carriage includes a first drive unit and a second drive unit. Thereby, in a trolley, the 1st acquisition guide device and the 2nd acquisition guide device operate independently of other devices. Therefore, the second catching and guiding device can perform an operation according to the state of the package and can perform a retry operation according to the situation. Therefore, the carriage can perform an efficient yarn joining operation according to the state of the package. Further, in the cart, the second catching and guiding device is driven by the second drive unit, so that a cam mechanism for driving the second catching and guiding device is not necessary. Thereby, the trolley | bogie can achieve weight reduction. As a result, it is possible to shorten the time from occurrence of yarn breakage or the like to completion of yarn joining.

  In one embodiment, the spinning device may be an air spinning device that generates a yarn by twisting a fiber bundle with a swirling flow of air. With this configuration, the efficiency of the yarn splicing operation can be improved in the spinning machine equipped with the pneumatic spinning device.

  In one embodiment, the pneumatic spinning device is disposed above the winding device in the spinning unit, and the yarn may travel from the upper side to the lower side in the height direction of the spinning unit.

  In one embodiment, the carriage may have a reverse rotation device that rotates the package in a direction in which the yarn is fed out when the second yarn is caught by the second catching and guiding device. In this configuration, when the second yarn is caught by the second catching and guiding device, the yarn end can easily come out from the package. Therefore, the second yarn catching accuracy by the second catching and guiding device can be improved.

  In one embodiment, the control unit may reciprocate the carriage by a predetermined distance in the arrangement direction when the second yarn is caught by the second catching and guiding device. In this configuration, the capture range of the second yarn by the second capture guide device is widened. Therefore, the second yarn can be captured by the second capture guide device more quickly and accurately.

  In one embodiment, when the yarn joining operation is not performed in the yarn joining device, the control unit may perform the suction operation by positioning the second catching and guiding device at a predetermined position. In this configuration, for example, by positioning the second catching and guiding device in the vicinity of the waxing device, wax waste or the like generated from the waxing device can be sucked and removed by the second catching and guiding device. Therefore, the spinning unit can be cleaned by the carriage that is not performing the yarn splicing operation, and the waiting time of the carriage can be effectively utilized.

  In one embodiment, a plurality of carriages are provided, and the control unit may set an area in the arrangement direction for each of the plurality of carriages and cause the carriage to perform a suction operation for each area. In this configuration, the spinning unit can be efficiently cleaned by the plurality of carriages.

  In one embodiment, the carriage includes a braking device that is movable to a contact position that contacts the package and a spaced position that is separated from the package, and brakes the rotation of the package at the contact position. When the second yarn cannot be captured by the capture guide device, the brake device may be moved to the contact position to contact the package. In this configuration, the braking device that brakes the rotation of the package when the second catching and guiding device catches the second yarn is brought into contact with the package again when the second catching and guiding device cannot catch the second yarn. Thereby, the effect which peels off the yarn end stuck on the surface of the package by the contact between the package and the braking device can be obtained. Accordingly, it is possible to improve the second yarn catching accuracy by the second catching and guiding device.

  In one embodiment, a position detection unit that detects the position of the second capture guide device may be provided. In this configuration, since the position of the second catching and guiding device can be grasped, the distance between the second catching and guiding device and the package can be adjusted.

  In one embodiment, the second catching and guiding device has a distance detection unit that detects a distance between the package and the second catching and guiding device, and the control unit is configured based on a detection result of the distance detecting unit. 2 The distance between the capture guide device and the package may be adjusted. In this configuration, the distance between the second catching and guiding device and the package can be set to an optimum distance for catching the second yarn. Therefore, it is possible to improve the second yarn catching accuracy by the second catching and guiding device. This configuration is realized by the fact that the second catching and guiding device can operate independently.

  In one embodiment, the control unit may move the second catching and guiding device to the initial position when the second catching and guiding device contacts another object. In the spinning machine according to the embodiment, since the second catching and guiding device operates independently, it can move to the initial position at an arbitrary timing, unlike the operation by the conventional cam mechanism.

  In one embodiment, the carriage has a yarn joining position at a yarn joining position where the first yarn and the second yarn are joined in the yarn joining device, and at a retracted position away from the yarn path where the yarn travels from the yarn joining position. You may provide the 3rd drive part only for a yarn splicing apparatus which moves an apparatus. In this configuration, the yarn joining device moves independently of the other devices. Therefore, the yarn joining device can move to the yarn joining position at an optimum timing according to the yarn catching status by the first catching and guiding device and the second catching and guiding device, and can perform the yarn joining operation at the yarn joining position.

  According to one aspect of the present invention, the efficiency of the yarn splicing operation can be improved.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In addition, in each figure, the same code | symbol is attached | subjected to the same or an equivalent part, and the overlapping description is abbreviate | omitted.

  As shown in FIG. 1, the spinning machine 1 includes a plurality of spinning units 2, a yarn splicing cart 3, a doffing cart (not shown), a first end frame 4, and a second end frame 5. I have. The plurality of spinning units 2 are arranged in a line. Each spinning unit 2 generates the yarn Y and winds it on the package P. The doffing cart doffs the package P and supplies a new bobbin B to the spinning unit 2 when the package P is full in a spinning unit 2.

  The first end frame 4 accommodates a collection device for collecting fiber waste and yarn waste generated in the spinning unit 2. The second end frame 5 is configured to adjust the air pressure of the compressed air (air) supplied to the spinning machine 1 to supply air to each part of the spinning machine 1 and to supply power to each part of the spinning unit 2. A drive motor or the like is stored. The second end frame 5 is provided with a machine control device (control unit, position detection unit) 15, a display screen 16, and input keys 17. The machine control device 15 centrally manages and controls each part of the spinning machine 1. The display screen 16 can display information regarding the setting contents and / or status of the spinning unit 2. When the operator performs an appropriate operation using the input keys 17, the setting operation of the spinning unit 2 can be performed.

  Each spinning unit 2 includes, in order from the upstream side in the traveling direction of the yarn Y, a draft device 6, an air spinning device 7, a yarn monitoring device 8, a tension sensor 9, a yarn storage device 11, a waxing device 12, A winding device 13. The unit controller 10 is provided for each predetermined number of spinning units 2 and controls the operation of the spinning units 2.

  The draft device 6 drafts a sliver (fiber bundle) S. The pneumatic spinning device 7 generates a yarn Y by twisting the fiber bundle F drafted by the draft device 6 by a swirling flow of air. More specifically (however, illustration is omitted), the pneumatic spinning device 7 includes a spinning chamber, a fiber guide portion, a swirling air flow generation nozzle, and a hollow guide shaft body. The fiber guide unit guides the fiber bundle F supplied from the upstream draft device 6 into the spinning chamber. The swirling airflow generation nozzle is disposed around the path along which the fiber bundle F travels. When air is injected from the swirling air flow generating nozzle, a swirling air flow is generated in the spinning chamber. By this swirling air flow, the fiber ends of the plurality of fibers constituting the fiber bundle F are reversed and swirled. The hollow guide shaft body guides the yarn Y from the spinning chamber to the outside of the pneumatic spinning device 7.

  The yarn accumulating device 11 takes the slack of the yarn Y between the pneumatic spinning device 7 and the winding device 13. The waxing device 12 applies wax to the yarn Y between the yarn storage device 11 and the winding device 13.

  The winding device 13 forms the package P by winding the yarn Y around the bobbin B. The winding device 13 includes a cradle arm 21, a winding drum 22, and a traverse guide 23. The cradle arm 21 supports the bobbin B so as to be rotatable. The cradle arm 21 is swingably supported by a support shaft 24 and brings the surface of the bobbin B or the surface of the package P into contact with the surface of the winding drum 22 with an appropriate pressure. A drive motor (not shown) provided on the second end frame 5 drives the winding drums 22 of the plurality of spinning units 2 all at once. Thereby, in each spinning unit 2, the bobbin B or the package P is rotated in the winding direction. The traverse guide 23 of each spinning unit 2 is provided on a shaft (not shown) shared by the plurality of spinning units 2. The traverse guide 23 traverses the yarn Y with a predetermined width with respect to the rotating bobbin B or package P by the drive motor of the second end frame 5 reciprocatingly driving the shaft in the direction of the rotation axis of the winding drum 22.

  The yarn monitoring device 8 monitors information on the traveling yarn Y between the pneumatic spinning device 7 and the yarn storage device 11, and detects the presence or absence of a yarn defect based on the monitored information. When the yarn monitoring device 8 detects a yarn defect, the yarn monitoring device 8 transmits a yarn defect detection signal to the unit controller 10. The tension sensor 9 measures the tension of the traveling yarn Y between the pneumatic spinning device 7 and the yarn storage device 11, and transmits a tension measurement signal to the unit controller 10. When the unit controller 10 determines that there is an abnormality based on the detection result of the yarn monitoring device 8 and / or the tension sensor 9, the yarn Y is cut in the spinning unit 2.

  In the spinning unit 2 having the above configuration, the pneumatic spinning device 7 is disposed above the winding device 13. Thereby, the yarn Y travels from the upper side to the lower side in the height direction of the spinning unit 2.

  When the yarn Y is cut by a certain spinning unit 2 or the yarn Y is cut for some reason, the yarn joining cart 3 performs a yarn joining operation with the spinning unit 2. One or a plurality of yarn joining carts 3 are provided in the spinning machine 1. The yarn joining cart 3 travels along the arrangement direction of the spinning units 2 (the left-right direction in FIG. 1). As shown in FIG. 1, the yarn splicing cart 3 travels by driving wheels by a travel motor 18. The operation of the traveling motor 18 is controlled by the machine base control device 15.

  As shown in FIG. 2, the yarn joining cart 3 includes a yarn joining device 26, a suction pipe (first catching and guiding device) 27, a suction mouth (second catching and guiding device) 28, a yarn guide 33, and a package. A plate (braking device) 34 and a reverse rotation device 35 are provided. As shown in FIG. 3, the yarn splicing carriage 3 includes a first drive unit 40 that drives the suction pipe 27, a second drive unit 41 that drives the suction mouse 28, and a third drive that drives the yarn splicing device 26. And a fourth drive unit 43 that drives the yarn guide 33, a fifth drive unit 44 that drives the package plate 34, and a sixth drive unit 45 that drives the reverse rotation device 35.

  The yarn joining device 26 performs yarn joining of the guided first yarn Y1 (see FIG. 7) and second yarn Y2 (see FIG. 7). The yarn joining device 26 is a splicer that uses compressed air or a knotter that mechanically joins the yarn Y. In the present embodiment, a splicer will be described as an example. The yarn joining device 26 includes a yarn joining portion 26a and a motor 26d.

  The yarn joining section 26a uncovers the yarn joining nozzle that connects the first yarn Y1 drawn from the pneumatic spinning device 7 and the second yarn Y2 drawn from the package P, and the yarn ends of the first yarn Y1 and the second yarn Y2. It has a flame-dissipating pipe, a clamp portion that sandwiches the first yarn Y1 and the second yarn Y2, and a yarn shifting lever and a yarn holding lever that regulate the first yarn Y1 and the second yarn Y2. The motor 26d is a drive source of a cam mechanism that operates the yarn shifting lever and the yarn holding lever of the yarn joining portion 26a.

  A support body 26b is provided at the yarn joining portion 26a. The support 26b is slidably attached to the rail 26c. The rail 26c is fixed to the housing of the yarn splicing cart 3, and extends in a direction substantially orthogonal to the traveling direction and the vertical direction of the yarn splicing cart 3.

  In the yarn joining device 26, the operation of the third driving unit 42 causes the yarn joining portion 26a supported by the support body 26b to move along the rail 26c. The yarn joining portion 26a includes a yarn joining position (see FIG. 7) where the yarn joining operation is performed, and a retracting position (see FIG. 2) where the yarn Y travels away from the yarn joining position and does not perform the yarn joining operation. , Is provided to be movable. The 3rd drive part 42 is a single acting cylinder, for example. One end of the single-acting cylinder that is the third drive unit 42 is connected to the support body 26 b, and the other end of the single-acting cylinder is fixed to the housing of the yarn splicing carriage 3.

  The third drive unit 42 is a drive source dedicated to the yarn joining device 26. Therefore, the yarn joining device 26 (yarn joining portion 26a) is movable independently of other devices. The term “dedicated” here means that no device other than the yarn joining device 26 is driven. For example, when wiring, piping, sensors, etc. are attached to the yarn joining device 26, the third drive unit 42 is dedicated to the yarn joining device 26 as long as each member moves together with the yarn joining device 26. As a driving source. In the following description, “dedicated” has the same meaning. The operation of the third drive unit 42 is controlled by the machine base control device 15.

  The yarn joining device 26 is provided with an elastic body (not shown) such as a spring. One end of the elastic body is connected to the support body 26b, and the other end of the elastic body is fixed to the housing of the yarn splicing carriage 3. The elastic body is arranged such that the expansion / contraction direction is along the expansion / contraction direction of the single acting cylinder which is the third drive unit 42. The elastic body is in an initial state (non-stretched state) when the single-action cylinder is not operating, and extends when the single-action cylinder is extended. With this configuration, the yarn joining portion 26a is returned from the yarn joining position to the retracted position by the contraction force of the elastic body. According to this configuration, the yarn joining portion 26a can be quickly moved from the retracted position to the yarn joining position by the operation of the single acting cylinder. In addition, since the elastic force of the elastic body acts when the yarn joining portion 26a stops at the yarn joining position, the yarn joining portion 26a can be gently stopped.

  The suction pipe 27 is rotatably supported by the support shaft 31, and captures the first yarn Y1 from the pneumatic spinning device 7 and guides it to the yarn joining device 26. The suction pipe 27 includes a standby position P11, a first yarn catching position P12 for catching the first yarn Y1 on the pneumatic spinning device 7 side, and a first yarn guiding position P13 (for guiding the first yarn Y1 to the yarn joining device 26). 7) and can be moved.

  The suction pipe 27 moves to the standby position P11, the first thread guide position P13, and the first thread guide position P13 by the operation of the first drive unit 40. The first drive unit 40 is, for example, a motor. The first drive unit 40 is a drive source dedicated to the suction pipe 27. Therefore, the suction pipe 27 can operate independently of other devices. The operation of the first drive unit 40 is controlled by the machine base control device 15.

  The suction mouse 28 is rotatably supported by the support shaft 32, captures the second yarn Y <b> 2 from the winding device 13, and guides it to the yarn joining device 26. The suction mouse 28 has a standby position (initial position) P21, a second yarn catching position P22 that catches the second yarn Y2 on the winding device 13 side, and a second yarn that guides the second yarn Y2 to the yarn joining device 26. It is movably provided at the guide position P23 (see FIG. 7). The suction mouse 28 is moved to the standby position P21, the second thread catching position P22, and the second thread guide position P23 by the operation of the second drive unit 41. The second drive unit 41 is, for example, a motor (stepping motor). The second drive unit 41 is a drive source dedicated to the suction mouse 28. Therefore, the suction mouse 28 can operate independently of other devices. The operation of the second drive unit 41 is controlled by the machine base control device 15.

  In the present embodiment, the suction mouth 28 is provided with an elastic body (not shown) such as a spring. Specifically, one end of the elastic body is connected to the suction mouth 28, and the other end of the elastic body is fixed to the housing of the yarn splicing cart 3. The elastic body is in an initial state (non-expanded state) when the suction mouse 28 is located at the standby position P21, and extends when the suction mouse 28 is located at the second thread catching position P22. According to this configuration, the torque (such as torque due to the weight of the suction mouth 28) when the suction mouth 28 is positioned at the second thread catching position P22 can be offset by the elastic force of the elastic body. Thereby, the suction mouse 28 can be moved at high speed.

  The suction mouse 28 is provided with a distance sensor (distance detection unit) 28a. The distance sensor 28 a is disposed at the tip of the suction mouse 28. The distance sensor 28a detects the distance between the suction mouse 28 and the package P. The distance sensor 28a is, for example, an optical distance measuring sensor. The distance sensor 28 a transmits a detection signal indicating the detection result to the machine base control device 15.

  The yarn guide 33 regulates the position of the yarn Y in the traveling direction. The yarn guide 33 is located between the yarn joining device 26 and the package P. The yarn guide 33 has a restriction plate 33a and two restriction bars 33b and 33c. One end of the restriction plate 33a is connected to a support shaft. Thereby, the restriction plate 33a is provided so as to be able to swing around the support shaft.

  As shown in FIG. 8, the restriction bars 33b and 33c are disposed on the restriction plate 33a. One ends of the restriction bars 33b and 33c are connected to a support shaft provided on the restriction plate 33a. Thereby, the control bars 33b and 33c are provided so as to be swingable around the support shaft by the operation of a drive source (not shown). The restricting bar 33b and the restricting bar 33c swing in the approaching direction close to each other and the separating direction separating from each other. In a position where the restriction bar 33b and the restriction bar 33c are close to each other, the restriction bar 33b and the restriction bar 33c extend in parallel to each other. At this time, the yarn Y sandwiched between the restriction bar 33b and the restriction bar 33c is positioned at the approximate center in the width direction of the package P.

  The yarn guide 33 is moved to a restriction position (see FIG. 5) where the restriction plate 33a overlaps the yarn path and a retreat position (see FIG. 2) where the restriction plate 33a does not overlap the yarn path by the swinging of the restriction plate 33a. It is provided as possible. The restriction position is a position where the yarn Y is restricted so that the yarn Y is not traversed by the traverse guide 23. When the restriction plate 33a is viewed from the side surface shown in FIG. 2, the position of its tip moves back and forth with respect to the yarn path by swinging. The yarn guide 33 moves to the restricting position and the retracted position by the operation of the fourth driving unit 43. The fourth drive unit 43 is, for example, a cylinder. The fourth drive unit 43 is a drive source dedicated to the yarn guide 33. Therefore, the yarn guide 33 can operate independently of other devices. The operation of the fourth drive unit 43 is controlled by the machine base control device 15.

  The package plate 34 positions the package P by pressing the surface of the package P supported by the winding device 13. The package plate 34 has a support arm 34a and a contact plate 34b. One end of the support arm 34a is connected to a support shaft. Thus, the support arm 34a is provided so as to be swingable about the support shaft. The contact plate 34b is provided at the other end of the support arm 34a. The contact plate 34 b is a plate member having a surface that contacts the package P.

  The package plate 34 has a retracted position (separated position) in which the contact plate 34b does not come into contact with the package P (see FIG. 2) and a contact position in which the contact plate 34b comes into contact with the package P (see FIG. 5). ) And can be moved. The package plate 34 moves to the retracted position and the contact position by the operation of the fifth driving unit 44. The fifth drive unit 44 is, for example, a motor. The fifth drive unit 44 is a drive source dedicated to the package plate 34. Therefore, the package plate 34 can operate independently of other devices. The operation of the fifth drive unit 44 is controlled by the machine base control device 15.

  The reverse rotation device 35 reversely rotates the package P of the winding device 13. The reverse rotation device 35 includes a support arm 35a and a reverse rotation roller 35b. One end of the support arm 35a is connected to a support shaft. Thus, the support arm 35a is provided so as to be swingable about the support shaft. The reverse rotation roller 35b is provided at the other end of the support arm 35a. The reverse rotation roller 35b rotates in a direction opposite to the winding drum 22 of the winding device 13 by a driving source (motor) (not shown).

  The reverse rotation device 35 includes a retracted position (see FIG. 2) where the reverse rotation roller 35b does not contact the package P due to the swing of the support arm 35a, and a contact position (see FIG. 6) where the reverse rotation roller 35b contacts the package P. It is provided to be movable. The reverse rotation device 35 is moved to the retracted position and the contact position by the operation of the sixth drive unit 45. The sixth drive unit 45 is, for example, a motor. The sixth drive unit 45 is a drive source dedicated to the reverse rotation device 35. Therefore, the reverse rotation device 35 can operate independently of other devices. The operation of the sixth drive unit 45 is controlled by the machine base control device 15.

  Next, the operation of the yarn joining cart 3 will be described with reference to FIG. The movement of each part of the yarn joining cart 3 will be described with reference to FIGS. 2 and 5 to 7. In the following description, the operation of each drive unit is controlled based on a control signal transmitted from the machine base control device 15.

  When yarn breakage or yarn cut occurs in one spinning unit 2, the machine base control device 15 transmits a control signal for moving the yarn joining cart 3 to the one spinning unit 2 to the yarn joining cart 3. When receiving the control signal, the yarn splicing carriage 3 travels to the one spinning unit 2 and the traveling motor 18 stops operating in front of the one spinning unit 2 to stop traveling.

  Next, the yarn guide 33 and the package plate 34 are activated. The fourth drive unit 43 operates when the yarn joining cart 3 stops or before it stops, and moves the yarn guide 33. The yarn guide 33 moves from the retracted position shown in FIG. 2 to the restriction position shown in FIG. 5, and stops at the restriction position. At this time, the restriction bars 33b and 33c of the yarn guide 33 are in a separated state.

  Further, the fifth drive unit 44 operates when the yarn joining cart 3 stops or before it stops, that is, at the same timing as the start of the operation of the fourth drive unit 43, and moves the package plate 34. The package plate 34 moves from the retracted position shown in FIG. 2 to the contact position shown in FIG. 5, and stops at the contact position. When the contact plate 34b of the package plate 34 contacts the package P, the rotation of the package P stops. The fifth drive unit 44 operates when the package plate 34 is stopped at the contact position for a predetermined time, and moves the package plate 34. The package plate 34 moves from the contact position shown in FIG. 5 to the retracted position shown in FIG. 6, and stops at the retracted position.

  Next, the reverse rotation device 35 operates. The sixth drive unit 45 operates during the return of the package plate 34 to the retracted position or when it stops at the retracted position, and moves the reverse rotation device 35. The reverse rotation device 35 moves from the retracted position shown in FIG. 2 to the contact position shown in FIG. 6, and stops at the contact position. When the reverse rotation roller 35b of the reverse rotation device 35 comes into contact with the package P, the package P rotates in the direction of feeding the second yarn Y2.

  In addition, the suction mouse 28 is activated. The second drive unit 41 operates when the package plate 34 returns to the retracted position or stops at the retracted position, that is, at the same timing as the start of the operation of the reverse rotation device 35, and moves the suction mouse 28. The suction mouse 28 moves from the standby position P21 shown in FIG. 2 to the second yarn catching position P22 shown in FIG. 6, and catches the second yarn Y2 at the second yarn catching position P22.

  The distance sensor 28 a of the suction mouse 28 detects the distance between the suction mouse 28 and the package P, and transmits a detection signal to the machine control device 15. The machine base control device 15 calculates the diameter of the package P based on the detection signal. Based on the calculated diameter of the package P and the diameter of the package P based on the length of the yarn Y (constant length), the machine base control device 15 determines whether the suction mouse 28 and the package P at the second yarn catching position P22 are Calculate the appropriate distance between. Further, the machine control device 15 stores the distance between the suction mouse 28 and the package P when the second yarn Y2 is captured by the suction mouse 28, and the suction mouse 28 is learned by learning based on the stored information. And the distance between the package P and the package P may be set. The second drive unit 41 operates based on the distance calculated by the machine control device 15.

  The second drive unit 41 operates when the second thread Y <b> 2 is captured by the suction mouse 28, and moves the suction mouse 28. The success or failure of capturing the second thread Y2 in the suction mouse 28 is determined by the machine control device 15 based on the detection result of a sensor (not shown) provided in the suction mouse 28. By the operation of the second drive unit 41, the suction mouse 28 moves from the second yarn catching position P22 shown in FIG. 6 to the second yarn guide position P23 shown in FIG. 7, and the second yarn Y2 is transferred to the yarn joining device 26. To guide you. The suction mouse 28 stops at the standby position P21 when the second yarn Y2 is guided to the yarn joining device 26.

  The machine control device 15 may reciprocate the yarn joining cart 3 by a predetermined distance in the traveling direction when the suction yarn 28 is used to capture the second yarn Y2. Further, the machine base control device 15 may bring the package plate 34 into contact with the package P when the suction yarn 28 is used to capture the second yarn Y2.

  The sixth drive unit 45 operates when the suction mouse 28 stops at the standby position P21, and moves the reverse rotation device 35. The reverse rotation device 35 moves from the contact position shown in FIG. 7 to the standby position shown in FIG. Thereby, the rotation of the package P is stopped.

  The yarn guide 33 operates the regulating bars 33b and 33c when the suction mouth 28 is positioned at the second thread guide position P23. Specifically, the regulation bars 33b and 33c are moved in the proximity direction. Accordingly, the second yarn Y2 captured by the suction mouse 28 is positioned by the regulation bars 33b and 33c.

  Next, the suction pipe 27 operates. The first drive unit 40 operates when the second thread Y2 is captured by the suction mouth 28 and the suction mouth 28 swings to a predetermined position, and moves the suction pipe 27. Specifically, when the second drive unit 41 is a stepping motor, the machine base control device 15 detects the position of the suction mouse 28 based on the number of pulses output to the stepping motor. The machine control device 15 detects the position of the suction mouse 28 and transmits a control signal to the first drive unit 40 when the suction mouse 28 reaches a predetermined position.

  By the operation of the first drive unit 40, the suction pipe 27 moves from the standby position P11 shown in FIG. 2 to the first yarn catching position P12 shown in FIG. 6, and at the first yarn catching position P12, the first yarn Y1 is moved. To capture. Whether or not the first pipe Y1 is captured by the suction pipe 27 is determined by the machine base control device 15 based on the detection result of a sensor (not shown) provided in the suction pipe 27. The first drive unit 40 operates when the first yarn Y1 is captured in the suction pipe 27, and moves the suction pipe 27. The suction pipe 27 moves from the first yarn catching position P12 shown in FIG. 6 to the first yarn guiding position P13 shown in FIG. 7, and guides the first yarn Y1 to the yarn joining device 26. The suction pipe 27 stops at the standby position P11 when the first yarn Y1 is guided to the yarn joining device 26.

  Next, the yarn joining device 26 operates. The third drive unit 42 has a timing at which the first yarn Y1 is captured by the suction pipe 27, a timing at which the suction pipe 27 starts moving to the first yarn guide position P13, or a first yarn guide position P13 of the suction pipe 27. It operates during movement to move the yarn joining portion 26a. The yarn joining portion 26a moves from the retracted position shown in FIG. 2 to the yarn joining position shown in FIG. 7, and stops at the yarn joining position. The yarn joining portion 26a performs the yarn joining operation of the first yarn Y1 and the second yarn Y2 at the yarn joining position.

  When the first yarn Y1 and the second yarn Y2 are connected, the yarn joining portion 26a releases the yarn Y. At this time, the yarn joining portion 26a injects air to the yarn Y. Specifically, the yarn joining portion 26a is provided with an air ejection device (not shown) that ejects air onto the yarn path. The yarn joining portion 26a removes slackness of the yarn Y by injecting air onto the yarn path. The time for injecting air from the air injection device of the yarn joining portion 26a to the yarn Y may be set as appropriate. Further, the yarn joining portion 26a may reciprocate the yarn wetting lever and the yarn holding lever at a predetermined angle when releasing the yarn Y by swinging the yarn feeding lever and the yarn holding lever. The thread holding lever may be opened step by step. Thereby, the released yarn Y is gradually released. Therefore, the slack that occurs when the yarn Y is released at once can be suppressed.

  The third drive unit 42 is activated when the injection of air to the yarn Y is completed, and moves the yarn joining unit 26a. The yarn joining portion 26a moves from the yarn joining position shown in FIG. 7 to the retracted position shown in FIG. 2, and stops at the retracted position. When the first yarn Y1 and the second yarn Y2 are connected at the yarn joining portion 26a, the restriction bars 33b and 33c of the yarn guide 33 move in the separating direction. As a result, the restriction of the yarn Y by the yarn guide 33 is released. The fourth drive unit 43 operates at the timing when the yarn joining portion 26a moves to the retracted position, and moves the yarn guide 33. The timing at which the fourth drive unit 43 operates is appropriately set according to the timing at which the yarn joining operation ends in the yarn joining portion 26a (timing at which the air injection to the yarn Y ends). The yarn guide 33 moves from the restricting position shown in FIG. 7 to the retracted position shown in FIG. Thus, the yarn joining operation by the yarn joining cart 3 is completed. When the yarn splicing operation is completed, the machine base control device 15 transmits, for example, a control signal for moving the yarn splicing cart 3 to the next spinning unit 2 to the yarn splicing cart 3. When the yarn splicing cart 3 receives the control signal, the traveling motor 18 operates.

  When the suction mouse 28 contacts the other object (such as the suction pipe 27) while the suction mouse 28 is moving, the machine base control device 15 transmits a control signal to the second drive unit 41, and the suction mouse 28 Is moved to the standby position P21. For example, when the second drive unit 41 is a stepping motor, the machine base control device 15 monitors the stepping motor step-out based on the output pulse and the detection result of the encoder. It is determined that an object has come into contact. When the machine control device 15 detects the contact between the suction mouse 28 and another object, the machine control device 15 moves the suction mouse 28 to the standby position P21, sets the operation timing of the suction mouse 28, and sends it to the second drive unit 41. Send a control signal.

  The machine control device 15 transmits a control signal to each of the drive units 40 to 45 when the power failure or the operation stop due to the contact with the obstacle or the like of the yarn joining cart 3 occurs in the yarn joining cart 3, and the yarn joining device 26. The operation of the suction pipe 27, the suction mouth 28, the yarn guide 33, the package plate 34, and the reverse rotation device 35 is automatically returned (for example, placed in the standby position).

  The yarn joining cart 3 may perform cleaning when the yarn joining operation is not performed. Cleaning is performed by the suction mouse 28. Specifically, the machine base control device 15 transmits a control signal to the second drive unit 41 and, for example, positions the suction port of the suction mouse 28 in the vicinity of the waxing device 12. As a result, wax waste generated from the waxing device 12 can be removed by suction with the suction mouse 28. When a plurality of yarn joining carts 3 are provided, the machine base control device 15 sets an area for performing cleaning by the yarn joining cart 3. The machine control device 15 causes the yarn joining cart 3 to perform cleaning for each set area.

A plate 34 is provided. When the second yarn Y2 cannot be captured by the suction mouse 28, the machine base control device 15 moves the package plate 34 to the contact position to contact the package P. In this configuration, the package plate 34 that brakes the rotation of the package P when the suction mouse 28 captures the second yarn Y2 is brought into contact with the package P again when the suction mouse 28 cannot capture the second yarn Y2. . Thereby, the effect of peeling off the yarn end stuck to the surface of the package P by the contact between the package P and the package plate 34 can be obtained. Therefore, it is possible to improve the capturing accuracy of the second yarn Y2 by the suction mouse 28.
