JP-A-2015-199559

  In the conventional yarn splicing carriage, the regulating 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 regulating device is included in a series of operations of the cam mechanism. Therefore, in the conventional yarn splicing cart, the regulating device can perform only a uniform operation. Thus, in the conventional textile machine, the timing at which the regulating device moves to the second position is uniquely set, and therefore the timing at which the yarn traverse is started cannot be adjusted. Further, in a conventional textile machine, the amount of yarn wound around the package cannot be arbitrarily changed.

  An object of one aspect of the present invention is to provide a textile machine that can adjust the timing of starting traversing of a yarn.

  A textile machine according to one aspect of the present invention includes a plurality of winding units, a cart that travels along an arrangement direction of the plurality of winding units, and a control unit that controls the operation of the cart, and the winding unit. Has a winding device that forms a package by winding the yarn supplied from the yarn feeding unit side, and the cart is a yarn of the yarn on the yarn feeding unit side and the yarn drawn from the package of the winding device. A yarn joining device that performs splicing, a catching guide device that catches and guides the yarn on the package side, and guides the yarn to the yarn joining device. A restriction device that can move to a first position that restricts the movement and a second position that does not contact the yarn, and a drive unit dedicated to the restriction device that moves the restriction device to the first position and the second position.

  In the textile machine according to one aspect of the present invention, the carriage includes a dedicated drive unit for moving the regulating device to the first position and the second position. Thereby, in a trolley | bogie, a control apparatus operate | moves independently of another apparatus. Therefore, in the cart, the movement of the first position and the second position of the restriction device can be arbitrarily controlled. Therefore, in the textile machine, it is possible to adjust the timing for starting the traverse of the yarn. Also, in textile machines, since the regulating device operates independently of other devices in the carriage, the amount of yarn wound around the package can be arbitrarily set according to the conditions (number, yarn type and / or spinning speed). Can change.

  In one embodiment, the regulating device may have a regulating unit that regulates the position of the yarn in the axial direction of the package. In this configuration, the movement of the yarn can be restricted when the yarn joining operation is performed in the yarn joining device. Accordingly, since yarn swaying is suppressed, the yarn joining operation can be performed well in the yarn joining device.

  In one embodiment, the controller may reciprocate the regulating device in a state where the regulating device and the yarn are in contact with each other when the yarn having a defect of a predetermined length or more is sucked and removed in the catching and guiding device. . In this configuration, it is possible to suppress the occurrence of reverse winding in which the yarn is wound around the package in the direction opposite to the winding direction.

  In one embodiment, the control unit may reciprocate the regulating device while the regulating device and the yarn are in contact with each other during the movement of the catching and guiding device that guides the yarn to the yarn joining device. In this configuration, it is possible to suppress the occurrence of reverse winding in which the yarn is wound around the package in the direction opposite to the winding direction.

  In one embodiment, the yarn supplying unit may be an air spinning device that generates a yarn by twisting the fiber bundle with a swirling flow of air. With this configuration, in the spinning machine equipped with the pneumatic spinning device, the timing for starting the traverse of the yarn can be adjusted.

  In one embodiment, the yarn supplying section is disposed above the winding device in the winding unit, and the yarn may travel from the upper side to the lower side in the height direction of the winding 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 yarn is caught by the catching and guiding device. In this configuration, when the yarn is caught by the catching and guiding device, the yarn end easily comes out from the package. Therefore, it is possible to improve the yarn catching accuracy by the catching guide device.

  In one embodiment, the carriage moves the yarn joining device to the yarn joining position where the yarn joining is performed in the yarn joining device, and the retracted position away from the yarn path where the yarn travels from the yarn joining position. The yarn splicing drive unit may be provided. In this configuration, the yarn joining device moves independently of the other devices. After the yarn joining operation is performed in the yarn joining device, the yarn may be slackened immediately after the yarn holding lever of the yarn joining device releases the yarn and the running of the yarn is started. Therefore, after performing the yarn joining operation in the yarn joining device, the slackness of the yarn can be removed while suppressing the slack yarn from being traversed by adjusting the timing of moving the regulating device to the second position. In this way, the behavior of the yarn can be controlled by adjusting the timing of movement between the yarn joining device and the regulating device.

  According to one aspect of the present invention, it is possible to adjust the timing of starting traversing of the yarn.

  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, a spinning machine (textile machine) 1 includes a plurality of spinning units (winding units) 2, a yarn splicing cart 3, a doffing cart (not shown), a first end frame 4, , A second end frame 5. 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 base control device (control 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 running direction of the yarn Y, a draft device 6, an air spinning device (yarn feeding unit) 7, a yarn monitoring device 8, a tension sensor 9, a yarn storage device 11, A waxing device 12 and a winding device 13 are provided. 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. However, the traveling direction of the yarn Y is not limited to this. For example, the yarn Y can travel from the lower side toward the upper side.

  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 27, a suction mouth (capturing guide device) 28, a yarn guide (regulating device) 33, and a package plate (braking device). 34 and a reverse rotation device 35. 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. A part (yarn splicing drive part) 42, a fourth drive part 43 for driving the yarn guide 33, a fifth drive part 44 for driving the package plate 34, a sixth drive part 45 for driving the reverse rotation device 35, have.

  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 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 surface of 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 direction orthogonal to the traveling direction of the yarn Y. The yarn guide 33 is located between the yarn joining device 26 and the package P. As shown in FIG. 8, the yarn guide 33 has a restriction plate 33a and two restriction bars (restrictions) 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.

  The regulation bars 33b and 33c regulate the position of the yarn Y in the axial direction of the package P. 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 has a regulation position P4 (first position) (see FIG. 5) for regulating that the regulation plate 33a comes into contact with the yarn Y and the yarn Y is positioned on the yarn path by swinging of the regulation plate 33a. The restriction plate 33a is provided so as to be movable to a retreat position P3 (second position) (see FIG. 2) where it does not contact the yarn Y. The restriction plate 33a overlaps the yarn path at the restriction position P4 and does not overlap the yarn path at the retracted position P3. The restriction position P4 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 is moved to the restriction position P4 and the retracted position P3 by the operation of the fourth drive 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. Further, the package plate 34 can brake the package P by making frictional contact with the surface of the package P. 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 34b is a plate member having a surface that contacts the surface of the package P.

  The package plate 34 has a retracted position (see FIG. 2) where the contact plate 34b does not contact the surface of the package P due to the swing of the support arm 34a, and a contact position (see FIG. 5) where the contact plate 34b contacts the surface of the package P. , Is provided to be movable. 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 has a retracted position (see FIG. 2) where the reverse rotation roller 35b does not contact the surface of the package P due to the swing of the support arm 35a, and a contact position where the reverse rotation roller 35b contacts the surface of the package P (see FIG. 6). And is movably provided. 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 P3 shown in FIG. 2 to the restriction position P4 shown in FIG. 5, and stops at the restriction position P4. 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 surface of the package P, the rotation of the package P stops. Further, the package P in contact with the package plate 34 is positioned. 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 surface of the package P, the package P rotates in a direction in which the second yarn Y2 is fed out.

  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 surface of 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 the suction mouth 28 and the surface of the package P at the second yarn catching position P22. Calculate the appropriate distance between. Further, the machine control device 15 stores the distance between the suction mouse 28 and the surface of the package P when the second yarn Y2 is captured by the suction mouse 28, and the suction mouse is learned by learning based on the stored information. You may set the distance between 28 and the package P surface. 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. Moreover, when the defect exists in the 2nd thread | yarn Y2, the suction mouse | mouth 28 sucks and removes the 2nd thread | yarn Y2 of the part in which the defect exists. 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 surface of the package P when capturing the second yarn Y2 with the suction mouse 28.

  The machine control device 15 controls the suction mouth 28 in a state in which the regulation plate 33a of the yarn guide 33 and the second yarn Y2 are in contact with each other when the suction yarn 28 removes the second yarn Y2 having a predetermined length or more. The plate 33a is reciprocated. The predetermined length is a length set by being input by an operator or the like using the input key 17. The machine base control device 15 acquires the length of the yarn defect based on the yarn defect detection signal output from the yarn monitoring device 8, and when the yarn defect is equal to or longer than the predetermined length, the machine control device 15 sends the control signal to the fourth drive unit 43. Send to. In the yarn guide 33, the regulation plate 33 a reciprocates (oscillates within a predetermined angle) by the operation of the fourth drive unit 43. The range in which the restriction plate 33 a reciprocates is set so that the second yarn Y <b> 2 does not hit the traverse guide 23.

  In addition, the machine control device 15 is configured such that the regulation plate 33a is in contact with the regulation plate 33a of the yarn guide 33 and the second yarn Y2 during the movement of the suction mouth 28 that guides the second yarn Y2 to the yarn joining device 26. May be reciprocated. Based on the lot of yarn Y to be generated, for example, when the yarn Y is thick, the machine control device 15 reciprocates the regulation plate 33a while the regulation plate 33a of the yarn guide 33 and the second yarn Y2 are in contact with each other. Let Whether or not the control is performed is set by an operator's selection, for example.

  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 retracted 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 P4 shown in FIG. 7 to the retracted position P3 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.

  As described above, in the spinning machine 1 according to the present embodiment, the yarn splicing cart 3 includes the dedicated fourth drive unit 43 for moving the yarn guide 33 to the restricting position P4 and the retracted position P3. Thereby, in the yarn splicing cart 3, the yarn guide 33 operates independently of other devices. Therefore, in the yarn splicing cart 3, the movement of the restriction position P4 and the retracted position P3 of the yarn guide 33 can be arbitrarily controlled. Therefore, the spinning machine 1 can adjust the start timing of the traverse of the yarn Y. Further, in the spinning machine 1, since the yarn guide 33 operates independently of other devices in the yarn splicing cart 3, depending on the conditions (number, yarn type and / or spinning speed), the yarn is fed to the package P. The amount of bar winding can be changed arbitrarily.

  In the conventional yarn splicing cart, the suction mouth is operated by the cam mechanism, and therefore the yarn guide may bounce (swing) due to the shape of the cam when the yarn guide returns to the retracted position. In the spinning machine 1 according to this embodiment, since the yarn guide 33 is operated by the fourth drive unit 43 dedicated to the yarn guide 33, the yarn guide 33 can be prevented from bouncing. As a result, it is possible to suppress a load from being applied to the yarn guide 33.

  In the spinning machine 1 according to the present embodiment, the yarn guide 33 has restriction bars 33b and 33c for restricting the position of the yarn Y in the axial direction of the package P. In this configuration, when the yarn joining operation is performed in the yarn joining device 26, the movement of the yarn Y can be restricted. Accordingly, since the yarn Y is prevented from shaking, the yarn joining device 26 can perform the yarn joining operation satisfactorily.

  In the spinning machine 1 according to the present embodiment, the machine base control device 15 is in a state where the yarn guide 33 and the yarn Y are in contact with each other when the yarn Y having a defect of a predetermined length or more is sucked and removed by the suction mouse 28. The yarn guide 33 may be moved back and forth. In this configuration, it is possible to suppress the occurrence of reverse winding in which the yarn Y is wound around the package P in the direction opposite to the winding direction.

  In the spinning machine 1 according to the present embodiment, the machine base control device 15 includes the yarn guide 33 in a state where the yarn guide 33 and the yarn Y are in contact with each other while the suction mouse 28 that guides the yarn Y to the yarn joining device 26 is moving.

Yes. In this configuration, when the second yarn Y <b> 2 is captured by the suction mouse 28, the yarn end can easily come out from the package P. Therefore, the capture accuracy of the second yarn Y2 by the suction mouse 28 can be improved.

  In the spinning machine 1 according to the present embodiment, the yarn joining cart 3 has the yarn joining position at which the first yarn Y1 and the second yarn Y2 are joined by the yarn joining device 26, and the yarn Y is more than the yarn joining position. A third drive unit 42 dedicated to the yarn joining device 26 is provided to move the yarn joining device 26 to a retracted position retracted from the traveling yarn path. In this configuration, the yarn joining device 26 moves independently of the other devices. After the yarn joining operation is performed in the yarn joining device 26, the yarn Y may be slackened immediately after the yarn pressing lever of the yarn joining device 26 releases the yarn Y and the running of the yarn Y is started. Therefore, after the yarn joining operation is performed in the yarn joining device 26, the yarn Y is slackened while the slack yarn Y is prevented from being traversed by adjusting the timing of moving the yarn guide 33 to the retracted position P3. Can be removed. Thus, by adjusting the timing of movement of the yarn joining device 26 and the yarn guide 33, the behavior of the yarn Y can be controlled.
