Description

Technical Field

[0001] The present invention relates to fiber machinery. Background Art

[0002] The spinning traction machine (fiber machine) described in Patent Documents 1 and 2 has a traction unit that traverses a plurality of yarns while winding them onto a plurality of bobbins to form a package. The traction unit has a plurality of fulcrum yarn guides that are arranged corresponding to the plurality of bobbins and serve as fulcrums when each yarn is traversed. The plurality of fulcrum yarn guides are driven, for example, by an air cylinder to move between a production position when the yarns are wound onto the bobbins and a spinning position that is closer to each other than when they are at the production position. The yarns are hung on the plurality of fulcrum yarn guides located at the spinning position by a spinning robot (see Patent Document 1) or an operator (see Patent Document 2).

[0004] Patent Document 2: Japanese Patent Application Publication No. 2015-78455

[0005] When a driving unit such as an air cylinder cannot operate normally due to accumulation of yarn scraps, etc., a threading target component such as a fulcrum guide cannot move normally. In this case, for example, the following defects may occur.

[0006] In the structure in which the threading robot is used to hang the thread on the threading target part, although it is not described in Patent Document 1, for example, when a predetermined time has passed since the threading target part was started to move, the movement is considered to be completed and the threading is continued. Therefore, if the threading is performed in a state where the threading target part is offset from the position where it should be, the threading will fail.

[0007] Furthermore, whether the threading is performed by a threading robot or by an operator, if the fulcrum thread guide does not return to the production position normally, the thread winding may start in a state where the fulcrum thread guide is offset from the position it should be in. As a result, there is a concern that the package may not be formed normally. Summary of the invention

[0008] An object of the present invention is to suppress a defect that occurs when a head-threading target member cannot move normally.

[0009] The fiber machinery of the first invention is a fiber machinery for processing at least one silk thread, and is characterized in that it comprises: a threading object component for hanging the above-mentioned silk thread; a driving unit for moving the above-mentioned threading object component between a predetermined production position and a threading position different from the above-mentioned production position; a detection unit for detecting information related to the movement of the above-mentioned threading object component achieved by the above-mentioned driving unit; and a control unit, which determines whether the movement of the above-mentioned threading object component is normal or abnormal based on the detection result of the above-mentioned detection unit.

[0010] In the present invention, when it is determined that the movement of the head threading target member is normal, the head threading can be performed, and when it is determined that the movement of the head threading target member is abnormal, the head threading can be stopped. Therefore, it is possible to suppress the malfunction caused when the head threading target member cannot move normally.

[0011] The fiber machine of the second invention is characterized in that, in the above-mentioned first invention, it is provided with an automatic threading device for threading the above-mentioned threading target component, and the above-mentioned control unit continues the operation of the above-mentioned automatic threading device only when it is determined that the movement of the above-mentioned threading target component is normal.

[0012] According to the present invention, when an abnormality occurs in the movement of the threading target member, it is possible to reliably prevent the threading robot from accidentally threading the thread.

[0013] A textile machine according to a third invention is characterized in that, in the first or second invention, a reporting unit for reporting information is provided, and when the control unit determines that an abnormality has occurred in the movement of the yarn threading object member, the reporting unit is caused to report information indicating the occurrence of the abnormality.

[0014] In the present invention, when abnormality occurs in the movement of the threading target component, it is possible to urge the operator to take prompt measures.

[0015] A textile machine according to a fourth aspect of the present invention is characterized in that, in any one of the first to third aspects of the present invention, the detection section detects information on the position of the yarn threading target member.

[0016] In the present invention, by using information on the position of the head-threading target member, it is possible to easily determine whether the movement of the head-threading target member is normal.

[0017] A textile machine according to a fifth aspect of the present invention is characterized in that, in the fourth aspect of the present invention, the position information detection section is a limit switch for detecting information on whether or not the thread-threading target member is located at a target position.

[0018] In the present invention, by using a generally inexpensive limit switch, it is possible to suppress an increase in the manufacturing cost of the textile machine and to easily determine whether the threading target member has reached the target position.

[0019] A textile machine according to a sixth aspect of the present invention is characterized in that, in the fourth or fifth aspect of the present invention, the driving section includes an air cylinder.

[0020] The air cylinder generally has a smaller thrust than an electric motor, so even a slight accumulation of wire scraps may cause the threading object to not move normally. In such a structure, it is effective to determine whether the movement of the threading object is normal based on the detection result of the position information detection unit.

[0021] A textile machine according to a seventh invention is the textile machine according to any one of the first to fifth inventions, wherein the drive unit includes an electric motor.

[0022] For example, if wire scraps are accumulated between the movable part and the fixed part of the electric motor, there is a concern that an excessive load is applied to the electric motor, causing the electric motor to malfunction. In the present invention, the operation of the electric motor is stopped when it is determined that the movement of the head object component is abnormal, thereby preventing the electric motor from being subjected to an excessive load.

[0023] A textile machine according to an eighth aspect of the present invention is characterized in that, in the seventh aspect of the present invention, the detection section detects information on a position of a movable section of the electric motor.

[0024] In the present invention, information on the position of the movable portion can be indirectly obtained. Therefore, even when information on the position of the head-threading component cannot be directly obtained, it is possible to determine whether the movement of the head-threading component is normal or abnormal.

[0025] A textile machine according to a ninth aspect of the present invention is characterized in that, in the seventh or eighth aspect of the present invention, the electric motor is a stepping motor, and the detection unit detects a step-out of the stepping motor.

[0026] In the present invention, by using information on the step-out, it is possible to determine whether the motor is operating normally. Therefore, even when information on the position of the head-threading target component cannot be obtained, it is possible to determine whether the movement of the head-threading target component is normal or abnormal.

[0027] The fiber machinery of the tenth invention is characterized in that, in any one of the first to ninth inventions, it comprises: a tube holder which supports a plurality of bobbins on which the plurality of the above-mentioned silk threads are respectively wound, arranged along the axial direction of the plurality of bobbins; and a plurality of traverse guides which are arranged along the axial direction corresponding to the plurality of bobbins and are used to traverse the plurality of silk threads respectively, the spinning object component comprises a plurality of fulcrum guides which are arranged along the axial direction respectively corresponding to the plurality of traverse guides and serve as fulcrums when the plurality of silk threads are respectively traversed, the plurality of fulcrum guides being able to move between a separation position which is the production position when the plurality of bobbins are respectively wound around the plurality of silk threads and a close position which is the spinning position and is concentrated in a manner where the interval in the axial direction becomes smaller than when it is in the separation position.

[0028] The multiple fulcrum yarn guides need to move a long distance between the separation position and the approach position. Therefore, when the action of the driving unit is unstable, there is a great concern that the target position cannot be reached normally. In such a structure, it is effective to judge whether the movement of the threading object component is normal based on the detection result of the detection unit.

[0029] The textile machine according to an eleventh invention is characterized in that, in the tenth invention, the detection section detects information on whether or not the plurality of fulcrum yarn guides are normally located at the separated positions.

[0030] When the yarn is wound onto the bobbin, if the plurality of fulcrum yarn guides are offset from the separated position, the yarn hung on the plurality of fulcrum yarn guides may not be normally wound onto the bobbin, and the yarn wound onto the bobbin may be wasted. In such a structure, it is effective to determine whether the movement of the plurality of fulcrum yarn guides is normal based on the detection result of the detection unit.

[0031] A textile machine according to a twelfth invention is characterized in that, in the tenth or eleventh invention, the detection section detects information on whether or not the plurality of fulcrum yarn guides are normally located at the proximity positions.

[0032] When the yarns are hung on the plurality of fulcrum yarn guides, if the plurality of fulcrum yarn guides are displaced from the close position, there is a concern that the yarns may not be properly threaded into the plurality of fulcrum yarn guides. In such a configuration, it is effective to determine whether the movement of the plurality of fulcrum yarn guides is normal based on the detection result of the detection unit.

The left-right direction is the direction orthogonal to the up-down direction and in which the traction units 3 described later are arranged. The front-back direction is the direction orthogonal to both the up-down direction and the left-right direction. In addition, the direction in which the thread Y travels is set as the thread travel direction. The axial direction of the plurality of bobbins B described later, which is roughly parallel to the front-back direction, is set as the bobbin axial direction (axial direction of the present invention).

[0068] (Spinning traction machine)

[0069] Reference Figure 1 The structure of the spinning and pulling machine 1 (textile machine of the present invention) according to the present embodiment will be described. Figure 1 1 is a front view of the spinning traction machine 1. Figure 1 As shown, the spinning traction machine 1 includes a plurality of spinning devices 2, a plurality of traction units 3 provided corresponding to the spinning devices 2, a spinning robot 4 (automatic spinning device of the present invention), and a centralized control device 100 (see Figure 3 ).

[0070] A plurality of spinning devices 2 are arranged in the left-right direction. Each spinning device 2 spins a plurality of yarns Y (e.g., 12 yarns). A plurality of traction units 3 are arranged below the plurality of spinning devices 2. The plurality of traction units 3 are arranged in the left-right direction corresponding to the plurality of spinning devices 2. Each traction unit 3 tractions the plurality of yarns Y spun from the spinning device 2, and simultaneously winds them onto a plurality of bobbins B (e.g., 12 yarns) to form a package P. The threading robot 4 is configured to move along a track 5 extending in the left-right direction, and threading is performed for each traction unit 3.

[0071] Centralized control device 100 (see Figure 3 The centralized control device 100 is electrically connected to a plurality of unit control devices 101 that control the plurality of traction units 3 and a spinning control device 102 that controls the spinning robot 4 (see Figure 3 The centralized control device 100 cooperates with the unit control device 101 and the spinning control device 102 to centrally control the entire spinning traction machine 1.

[0072] (Traction unit)

[0073] Next, refer to Figure 2 , Figure 3 The structure of the traction unit 3 will be described. Figure 2 It is a side view of the traction unit 3 and the threading robot 4. Figure 3 1 is a block diagram showing the electrical structure of the spinning traction machine 1. Figure 2 As shown, the drawing unit 3 includes a yarn aspirator 11 , a yarn regulating guide 12 , a first yarn godet roller 13 , a second yarn godet roller 14 , and a winding section 15 .

[0074] The aspirator 11 is disposed at the front end of the traction unit 3. The aspirator 11 is configured to suck and hold a plurality of yarns spun from the spinning device 2 before the traction unit 3 is threaded.

[0075] The limiting wire guide 12 is, for example, a well-known comb-shaped wire guide. Figure 2 As shown, the limiting yarn guide 12 is arranged on the lower side of the yarn aspirator 11. The limiting yarn guide 12 is configured to arrange the plurality of yarns Y in the left-right direction. The limiting yarn guide 12 limits the movement of the yarns Y in the left-right direction so that when the plurality of yarns Y are hung, the intervals between the adjacent yarns Y are set to a predetermined interval. The limiting yarn guide 12 is, for example, controlled by a cylinder 111 (see Figure 3 ) is driven to move in the left-right direction. The yarn guide 12 is limited to the production position when the yarn Y is wound onto the bobbin B (refer to Fig. 9 (d) double-dashed line), and the threading position when threading (refer to Fig. 9 (d) (solid line).

[0076] The first godet roller 13 is a roller whose axial direction is substantially parallel to the left-right direction. Figure 2 As shown, the first godet roller 13 is disposed below the regulating yarn guide 12. The first godet roller 13 is rotationally driven by a motor (not shown) to feed the yarn Y to the downstream side in the yarn running direction.

[0077] The second godet roller 14 is a roller whose axial direction is substantially parallel to the left-right direction. Figure 2 As shown in FIG. 1 , the second guide roller 14 is arranged above and behind the first guide roller 13. The second guide roller 14 is driven to rotate by a motor (not shown) to transport the yarn Y to the downstream side of the yarn travel direction. The second guide roller 14 is supported by a guide rail 16 extending upward and backward in an inclined manner so as to be movable. The second guide roller 14 is configured to be movable by, for example, a moving motor 112 (see FIG. 1 ). Figure 3 ), unillustrated pulley pairs, belts, pneumatic devices, etc., move along the guide rail 16. Thus, the second godet roller 14 can be in the production position (refer to Figure 2 The solid line) and the threading position when the threading is performed close to the first godet roller 13 (refer to Figure 2 double-dotted line).

[0078] The winding unit 15 is configured to wind the plurality of yarns Y around the plurality of bobbins B to form a package P. Figure 2 As shown, the winding section 15 is arranged below the first godet roller 13, the second godet roller 14, etc. The winding section 15 includes a frame 20, a plurality of fulcrum guides 21 (threading object components of the present invention), a plurality of traverse guides 22, a turntable 23, two bobbin holders 24, a contact roller 25, and a unit control device 101.

[0079] The frame 20 is, for example, a component installed on the floor of a workshop and for mounting or accommodating the components of the winding unit 15. Figure 2 As shown, the frame 20 includes a base portion 20a provided on the ground and extending in the front-rear direction, a rear portion 20b provided upright at the rear end of the base portion 20a, and an upper portion 20c extending forward from the upper portion of the rear portion 20b.

[0080] The plurality of fulcrum yarn guides 21 are yarn guides that serve as fulcrums when the yarn Y is traversed by the traverse yarn guides 22. Figure 2 As shown in FIG. 1 , a plurality of fulcrum guides 21 are independently provided with respect to a plurality of yarns Y and arranged in the front-rear direction. Each fulcrum guide 21 has a groove 21a (see FIG. 1 ) opening toward the rear side. Figure 5(a), (b)), the yarn Y can be inserted into the groove 21a from the rear side to accommodate the yarn Y. In addition, each fulcrum yarn guide 21 has a cylindrical assembly portion 21b opened in the front-to-back direction. The assembly portion 21b is movably assembled to the yarn guide support body 26 extending in the front-to-back direction (see Figure 5 (a), (b)). The yarn guide support body 26 is, for example, a hollow cylindrical member fixed to the upper portion 20c of the frame 20. The plurality of fulcrum yarn guides 21 are driven by a drive unit 30 described later and move in the front-rear direction along the yarn guide support body 26 during yarn spinning.

[0081] A plurality of traverse guides 22 are independently provided relative to a plurality of yarns Y and arranged in a front-to-back direction. The traverse guides 22 are, for example, known blade-type guides. The traverse guides 22 are, for example, driven back and forth in the front-to-back direction by a motor (not shown). Thus, the yarns Y traverse in the front-to-back direction with the fulcrum guide 21 as a fulcrum.

[0082] The turntable 23 is a disc-shaped component whose axial direction is roughly parallel to the front-back direction. The turntable 23 is driven to rotate by a motor not shown in the figure. Two bobbin holders 24 are respectively supported on the upper end and lower end of the turntable 23 in an axial direction parallel to the front-back direction and rotatably. In each bobbin holder 24, a plurality of bobbins B independently provided with respect to a plurality of silk threads Y are arranged and assembled along the front-back direction (bobbin axial direction) and supported to be rotatable. The two bobbin holders 24 are respectively driven to rotate by independent motors (not shown in the figure).

[0083] 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 plurality of packages P supported by the upper bobbin holder 24 to apply contact pressure to the surfaces of the packages P being wound, thereby adjusting the shape of the packages P.

[0084] Unit control device 101 (see Figure 3 ) has a CPU, ROM, RAM, etc., and is configured to perform control for operating the cylinder 111, the moving motor 112, etc. In addition, the unit control device 101 has an operation unit 121 (see Figure 3 ), and a reporting unit 122 (refer to Figure 3 ). The operation unit 121 has, for example, an operation button not shown. The notification unit 122 has, for example, an alarm lamp not shown. The unit control device 101 and the central control device 100 (see Figure 3 ) is electrically connected to communicate with the centralized control device 100.

[0085] In the winding section 15 having the above structure, when the upper bobbin holder 24 is driven to rotate, the yarn Y traversed by the traversing yarn guide 22 is wound around the bobbin B to form a package P. When the package P is full, the upper and lower positions of the two bobbin holders 24 are interchanged by rotating the turntable 23. As a result, the bobbin holder 24 located at the lower side moves upward, and the yarn Y can be wound around the bobbin B mounted on the bobbin holder 24 to form a package P.

[0086] (Driver)

[0087] Reference Figure 4 as well as Figure 5 (a) and (b) illustrate the driving unit 30 that moves the plurality of fulcrum yarn guides 21. Figure 4 2 is an explanatory diagram showing the driving unit 30 . Figure 5 (a) and (b) are explanatory diagrams showing the movement of the fulcrum yarn guide 21. Figure 4 As shown, the driving unit 30 includes an air cylinder 31 and a movable member 32. The air cylinder 31 moves the plurality of fulcrum yarn guides 21 by moving the movable member 32 connected to the rearmost fulcrum yarn guide 21.

[0088] The air cylinder 31 is, for example, a rodless air cylinder extending in the front-rear direction. The operation of the air cylinder 31 is controlled by the unit control device 101 (see Figure 3 ) control. Figure 4 As shown, the cylinder 31 is housed inside the yarn guide support 26. The cylinder 31 includes a cylinder body 33, a piston 34 built in the cylinder body 33 and movable in the front-rear direction, and a slider 35 connected to the piston 34 and arranged outside the cylinder body 33.

[0089] The cylinder body 33 extends in the front-back direction. A cylinder chamber 33a and a cylinder chamber 33b are formed inside the cylinder body 33. The cylinder chamber 33a is formed on the front side of the piston 34. The cylinder chamber 33a is connected to a pipe 36a extending to the outside of the guide support body 26. The cylinder chamber 33b is formed on the rear side of the piston 34. The cylinder chamber 33b is connected to a pipe 36b extending to the outside of the guide support body 26. The pipes 36a and 36b are connected to a supply port (not shown) or a discharge port (not shown) of compressed air, for example, via a known 4-way solenoid valve (not shown). The 4-way solenoid valve can switch the state of the drive unit 30 between the following first state and second state. In the first state, the pipe 36a is connected to the supply port, and the pipe 36b is connected to the discharge port. In the second state, the pipe 36b is connected to the supply port, and the pipe 36a is connected to the discharge port. When the state of the driving unit 30 is the first state, compressed air is supplied to the cylinder chamber 33a and the compressed air is discharged from the cylinder chamber 33b. As a result, the piston 34 and the slider 35 move toward the rear side (see Figure 4On the contrary, when the state of the driving unit 30 is the second state, the piston 34 and the slide member 35 move toward the front side (refer to Figure 4 A magnet (not shown) is fixed to the slider 35, for example.

[0090] The movable member 32 is mounted on the yarn guide support body 26 and is configured to be movable in the front-rear direction (the bobbin axial direction) along the yarn guide support body 26. The rearmost fulcrum yarn guide 21 (fulcrum yarn guide 21R) is fixed to the movable member 32 (see Figure 5 (a), (b)). A magnet (not shown) is fixed to the movable member 32, for example. Thus, the movable member 32 is connected to the slider 35 by means of magnetic force. When the slider 35 moves in the front-rear direction, the movable member 32 follows the slider 35 by means of magnetic force, and moves along the bobbin axial direction together with the fulcrum yarn guide 21R (the fulcrum yarn guide arranged at the rear side among the plurality of fulcrum yarn guides 21).

[0091] Furthermore, the above-mentioned multiple fulcrum yarn guides 21 are connected to each other, for example, by means of a belt not shown. More specifically, two fulcrum yarn guides 21 adjacent to each other in the front-to-back direction (axial direction of the bobbin) are connected by a belt. If the movable member 32 and the fulcrum yarn guide 21R move toward the rear side, the other fulcrum yarn guides 21 are pulled toward the rear side by the above-mentioned belt. When the fulcrum yarn guide 21R moves to the rear end of the movable range, the multiple fulcrum yarn guides 21 are arranged at approximately equal intervals at intervals specified by the length of the belt (refer to Figure 5 At this time, the plurality of fulcrum yarn guides 21 are located directly above the corresponding bobbin B (refer to Figure 2 ). The position of the multiple fulcrum yarn guides 21 at this time is called the separation position (also equivalent to the production position of the present invention). And, if the movable part 32 and the fulcrum yarn guide 21R move toward the front side, the assembly part 21b of the other fulcrum yarn guides 21 is pushed by the fulcrum yarn guide 21R. As a result, the multiple fulcrum yarn guides 21 move and concentrate on the front side. At this time, the multiple fulcrum yarn guides 21 are closer to each other (the interval becomes narrower) than when they are in the separation position. The position of the multiple fulcrum yarn guides 21 at this time is called the approach position (also equivalent to the head production position of the present invention). As above, the multiple fulcrum yarn guides 21 can move between the separation position and the approach position different from the separation position.

[0092] (Production Execution Department)

[0093] The traction unit 3 is provided with a threading execution section 40 (see FIG. 1 ) configured to hook the yarn Y hooked on the fulcrum yarn guide 21 on the traverse yarn guide 22 and the bobbin B. Figure 6 ). Below, refer to Figure 6 as well as Figure 7 (a) and (b) are described below. Figure 6It is a schematic diagram of the threading execution unit 40. Figure 7 (a) and (b) are explanatory diagrams of a first separation device 42 described later. Figure 7 (c) is an explanatory diagram of the second separation device 43 described later. Figure 6 View from the VII direction.

[0094] like Figure 6 As shown, the threading execution unit 40 includes, for example, a yarn bundling guide 41, a first separating device 42, and a second separating device 43. The yarn bundling guide 41 is configured to bundle the plurality of yarns Y to the front end of the traction unit 3. The first separating device 42 temporarily holds the plurality of yarns Y hung on the plurality of fulcrum yarn guides 21. The second separating device 43 receives the yarns Y from the first separating device 42 and performs actions such as bringing the yarns Y close to the bobbin B.

[0095] The wire bundle guide 41 is arranged at the front end of the traction unit 3. Figure 1 As shown, the wire bundle guide 41 is mounted on the front end of an arm-shaped swing member 44 that can swing in the forward and backward direction as the swing axis. The swing member 44 is driven by, for example, an air cylinder 113 (see Figure 3 ) is swung and driven. Thus, the wire bundle guide 41 can be at the initial position (refer to Figure 6 solid line) and the intersection position to the left of the initial position (reference Figure 6 The dotted lines in the figure indicate the position of the oscillator.

[0096] like Figure 7 As shown in (a) and (b) of FIG. 1 , the first separating device 42 includes: a guide member 51 extending in the front-to-back direction; and a plurality of holding members 52 arranged in the front-to-back direction and mounted on the guide member 51 in a movably manner. The guide member 51 is configured to be movable by, for example, a cylinder 114 (see FIG. 1 ). Figure 3 ) and moves in the left-right direction. The guide member 51 can be in the initial position (refer to Figure 6 solid line) and the intersection position to the left of the initial position (reference Figure 6 Move between the dashed lines). Figure 7 As shown in (a) and (b), the holding member 52 has a main body 52a and a protrusion 52b for preventing the thread Y from falling off. The plurality of holding members 52 are connected to each other by, for example, a belt not shown in the figure, and are driven by a cylinder 115 (see Figure 3 Specifically, the plurality of holding members 52 can be in a first position (refer to Figure 7 (a)) and the second position of the set of positions closer to the front side than the first position (refer to Figure 7 (b)).

[0097] The second separation device 43 is arranged on the left side of the first separation device 42. The second separation device 43 includes: an arm-shaped swing member 53 extending in the front-back direction and capable of swinging with the front-back direction as the swing axis center; and a holding member 54 fixed to the front end of the swing member 53. At the end of the holding member 54 on the opposite side to the swing member 53, for example, Figure 7 As shown in (c), a through space 54a for thread Y to be inserted is formed in the front-to-back direction. In addition, protrusions 54b and 54c are provided at the entrance of the through space 54a to prevent the thread Y from falling off. The swing member 53 and the holding member 54 are, for example, controlled by an air cylinder 116 (see Figure 3 ) is swung and driven. Thus, the swing member 53 and the holding member 54 can be moved to a predetermined retreat position (refer to Figure 6 The solid line) is compared with the receiving position for receiving the yarn Y from the first separating device 42 on the right side of the retreat position (refer to Figure 6 Furthermore, although not shown in the figure, the second separating device 43 is configured so that after receiving the yarn Y from the first separating device 42, the reciprocating traverse yarn guide 22 can capture the yarn Y by moving the holding member 54 to the left from the receiving position.

[0098] Furthermore, a wire drawing device (not shown) is provided in the threading execution unit 40. The wire drawing device is configured to temporarily disengage the yarn Y captured by the traverse yarn guide 22 from the traverse yarn guide 22 and guide it toward the slit (not shown) of the bobbin B (further description is omitted. For details, please refer to, for example, Japanese Patent Publication No. 2017-154891).

[0099] (Head-raising robot)

[0100] return Figure 2 , the structure of the threading robot 4 will be described. The threading robot 4 includes a main body 61, a robot arm 62, a threading unit 63, and a threading control device 102 (see Figure 3 ).

[0101] The main body 61 is a substantially rectangular parallelepiped member. The main body 61 is moved by a motor 131 (see Figure 3 ) is driven to move in the left-right direction. The robot arm 62 is mounted on the lower surface of the main body 61. The robot arm 62 has a plurality of arms 62a and a plurality of joints 62b that connect the arms 62a to each other. An arm motor 132 (see Figure 3 ). When the arm motor 132 is driven, the arm 62a swings around the joint 62b. The weaving unit 63 is mounted on the front end of the robot arm 62. The weaving unit 63 includes a suction pipe 64, a cutter 65, and a weaving auxiliary component 66 (see Figure 5(b)). The suction pipe 64 is configured to suck and hold the yarn Y in the yarn. The cutter 65 is configured to cut the yarn Y when the yarn Y is delivered from the yarn aspirator 11 to the yarn unit 63 (described later). The yarn auxiliary component 66 has a plurality of holding grooves 66a (see Figure 5 (b)), multiple wires Y are held separately by multiple holding grooves 66a.

[0102] The threading control device 102 ( Figure 3 The spinning control device 102 has a CPU, ROM, RAM, etc., and is configured to control the moving motor 131, the arm motor 132, and the spinning unit 63. After the main body 61 is moved to the front of the traction unit 3 as the spinning target, the spinning control device 102 controls the robot arm 62 to spin the yarn to the traction unit 3 while holding the yarn Y. The spinning control device 102 is connected to the centralized control device 100 (refer to FIG. 1 ). Figure 3 ) is electrically connected to communicate with the centralized control device 100.

[0103] Next, before explaining the spinning yarn in detail, problems that may occur in a conventional spinning pull-up machine and a detailed structure of the spinning pull-up machine 1 in the present embodiment will be explained.

[0104] (Existing Problems)

[0105] In the past, for example, when a predetermined time has passed since the fulcrum yarn guide 21 started to move, the unit control device 101 determined that the movement of the fulcrum yarn guide 21 was completed, and continued the threading by the threading robot 4. However, for example, when the cylinder 31 cannot operate normally and the fulcrum yarn guide 21 cannot move normally, the fulcrum yarn guide 21 cannot be normally located at the approach position or the separation position. When the fulcrum yarn guide 21 is not normally located at the approach position, the threading by the threading robot 4 fails to occur. In addition, when the fulcrum yarn guide 21 fails to return normally from the approach position to the separation position, the winding of the yarn Y will begin in a state where the fulcrum yarn guide 21 is offset from the original position. In this way, there is a concern that the package cannot be formed normally, the wound yarn Y and the time spent on winding will be wasted.

[0106] In addition, as one of the reasons why the cylinder 31 cannot operate normally, for example, the increase in load caused by the accumulation of silk scraps between the cylinder body 33 and the slider 35 can be cited. The silk scraps, for example, include powdery silk scraps generated by the scraping between a part of the traveling yarn Y and the guide components such as the fulcrum yarn guide 21. Such silk scraps, for example, may enter the internal space of the yarn guide support 26, so it is difficult to completely prevent the accumulation of silk scraps. Or, as another reason, when the supply source of compressed air is commonly connected to multiple cylinders including the cylinder 31, the pressure of the compressed air is insufficient when the multiple cylinders operate simultaneously. In such a case, it is also difficult for the cylinder to operate normally. Therefore, in this embodiment, in order to suppress the malfunction caused when multiple fulcrum yarn guides 21 (yarn object components) cannot move normally, the spinning traction machine 1 is configured as follows. More specifically, a position information detection unit 70 described later is arranged near the multiple fulcrum yarn guides 21.

[0107] (Detailed structure of spinning traction machine)

[0108] return Figure 5 (a) and (b) of the present invention will be described to explain the detailed structure of the spinning traction machine 1 (more specifically, the structure near the fulcrum yarn guide 21). As described above, the movable member 32 is assembled in the yarn guide support body 26 in a manner that can move in the front-rear direction. The left end of the movable member 32 protrudes to the left side compared to the left end of the fulcrum yarn guide 21, for example. A position information detection unit 70 (the detection unit of the present invention) that detects information related to the current position of the fulcrum yarn guide 21 is provided near such a movable member 32. In other words, the position information detection unit 70 detects information related to the movement of the fulcrum yarn guide 21. The position information detection unit 70 has a first limit switch 71 and a second limit switch 72 (both equivalent to the limit switches of the present invention) that detect information related to whether the fulcrum yarn guide 21 is located at the target position. The first limit switch 71 and the second limit switch 72 are, for example, switch devices with a well-known built-in contact micro switch. The drive mechanism of the micro switch can apply various types of drive mechanisms such as a well-known push rod and a hinge rod. Alternatively, the first limit switch 71 and the second limit switch 72 (limit switch) may also be known non-contact proximity sensors. As for the limit switch, as a non-contact proximity sensor, a proximity sensor of a type that detects the approach of a metal body by electromagnetic induction or a Hall element can be applied. The first limit switch 71 and the second limit switch 72 are electrically connected to the unit control device 101. In addition, the following description assumes that the first limit switch 71 and the second limit switch 72 are contact limit switches.

[0109] The first limit switch 71 is configured to detect whether the movable member 32 and the fulcrum yarn guide 21R (the fulcrum yarn guide arranged at the rearmost side among the plurality of fulcrum yarn guides 21) are normally located at the approach position. Figure 5 As shown in (a) and (b), the first limit switch 71 is arranged at a position closer to the front side than the left end portion of the movable part 32. The first limit switch 71 is arranged at a position closer to the left side than the plurality of fulcrum wire guides 21. Therefore, the fulcrum wire guide 21 will not interfere with the first limit switch 71 when it moves along the axial direction of the bobbin. The first limit switch 71 is arranged to contact the left end portion of the movable part 32 when the movable part 32 moves to the approach position. When the movable part 32 contacts the first limit switch 71, the first limit switch 71 is turned on. When the movable part 32 does not contact the first limit switch 71, the first limit switch 71 is turned off. Thus, the first limit switch 71 can detect information related to whether the movement of the movable part 32 to the approach position is normal. With respect to the first limit switch 71, the approach position is equivalent to the target position of the present invention.

[0110] The second limit switch 72 is configured to detect whether the movable member 32 and the fulcrum yarn guide 21R are normally located at the separated position. Figure 5 As shown in (a) and (b), the second limit switch 72 is arranged at a position farther back than the left end of the movable part 32. The second limit switch 72 is arranged at a position substantially the same as the first limit switch 71 in the left-right direction. Furthermore, the second limit switch 72 is arranged to overlap with the left end of the movable part 32 in the left-right direction. The second limit switch 72 is arranged to contact the left end of the movable part 32 when the movable part 32 moves to the separation position. When the movable part 32 contacts the second limit switch 72, the second limit switch 72 is turned on. When the movable part 32 does not contact the second limit switch 72, the second limit switch 72 is turned off. Thus, the second limit switch 72 can detect information related to whether the movement of the movable part 32 to the separation position is normal. With respect to the second limit switch 72, the separation position is equivalent to the target position of the present invention.

[0111] (Judgment regarding the movement of the fulcrum guide during yarn spinning, etc.)

[0112] Next, regarding the determination of whether the movement of the fulcrum yarn guide 21 is normal or abnormal during the yarn threading of the traction unit 3 and the response based on the determination, together with the specific procedure of yarn threading, refer to Figure 8 to Figure 11 Provide explanation. Figure 8 1 is a flowchart showing the procedure of threading. Fig. 9 (a)~ Fig.11 This is an explanatory diagram showing the steps of threading. Fig. 9 (d) is Fig. 9The central control device 100, the unit control device 101, and the head-spinning control device 102 cooperate with each other to control the various parts of the traction unit 3 and the head-spinning robot 4, thereby performing the head-spinning. In this embodiment, the central control device 100, the unit control device 101, and the head-spinning control device 102 together correspond to the control unit of the present invention.

[0113] In the initial state, the plurality of silk threads Y are held by the silk aspirator 11 (see Fig. 9 (a)). In this state, the head spinning starts (S101). Specifically, a signal for causing the traction unit 3 to perform the action required for head spinning is sent from the central control device 100 to the unit control device 101 of the traction unit 3 to be the target of head spinning. In addition, a signal for causing the main body 61 of the head spinning robot 4 to move to the front of the traction unit 3 is sent from the central control device 100 to the head spinning control device 102. The head spinning control device 102 controls the moving motor 131 based on the signal to move the main body 61 in the left-right direction.

[0114] Next, the unit control device 101 controls each part of the traction unit 3 to start moving each part to be spun-in from the production position to the spun-in position (S102). Specifically, the second godet roller 14 starts to move to the spun-in position by the movement motor 112, and the plurality of fulcrum guides 21 starts to move to the approach position (spun-in position) by the air cylinder 31.

[0115] Next, the unit control device 101 determines whether the fulcrum yarn guide 21 has moved normally to the approach position (threading position) within a predetermined time from the start of the movement of the fulcrum yarn guide 21. Specifically, in the next step S103, when the movable member 32 contacts the first limit switch 71 and the first limit switch 71 is turned on (S103: Yes), the unit control device 101 determines that the fulcrum yarn guide 21 has moved normally to the approach position. On the other hand, when the first limit switch 71 is turned off (S103: No), the unit control device 101 returns to step S103 until the predetermined time has passed (S104: No).

[0116] When a predetermined time has passed since the fulcrum yarn guide 21 started to move toward the approach position and the first limit switch 71 remained in the off state (S104: Yes), the unit control device 101 determines that the movement of the fulcrum yarn guide 21 toward the approach position is abnormal. Accordingly, the spinning-in is stopped. Specifically, the unit control device 101 stops the operation of each part of the traction unit 3, and sends a signal indicating that the movement of the fulcrum yarn guide 21 is abnormal to the centralized control device 100. The centralized control device 100 sends a signal for stopping the spinning-in to the spinning-in control device 102. In addition, the unit control device 101 controls the reporting unit 122 to report information indicating that the movement of the fulcrum yarn guide 21 is abnormal (S105). The operator confirms the state of the traction unit 3 based on the information reported by the reporting unit 122. In addition, the operator performs maintenance on the traction unit 3 as needed.

[0117] On the other hand, when the first limit switch 71 is turned on before a predetermined time has passed (S103: Yes), the unit control device 101 immediately sends a signal to the central control device 100 indicating that the movement of the fulcrum yarn guide 21 is normal. Based on the signal received from the unit control device 101, the central control device 100 sends a signal for continuing the operation of the spinning robot 4 to the spinning control device 102. The spinning control device 102 operates the spinning robot 4 in accordance with the signal. Specifically, in a state where the suction tube 64 is located near the yarn Y sucked and held by the yarn aspirator 11, the yarn Y is cut by the cutter 65. As a result, the yarn Y is handed over from the yarn aspirator 11 to the spinning unit 63 (S106. Refer to Fig. 9 In this way, only when it is determined that the movement of the fulcrum yarn guide 21 is normal, the operation of the yarn spinning robot 4 is continued.

[0118] In the next step S107, the threading robot 4 performs threading toward the limiting thread guide 12, the first thread guide roller 13, and the second thread guide roller 14. More specifically, the threading control device 102 uses the robot arm 62 to move the front end of the threading unit 63 to a position below, behind, and to the right of the limiting thread guide 12 (see FIG. Fig. 9 (c) and Fig. 9 Then, the unit control device 101 causes the limiting yarn guide 12 to move from the production position (refer to Fig. 9 The double-dotted line (d) of the head is toward the head position (refer to Fig. 9 Next, the spinning control device 102 moves the spinning unit 63 forward to hang the plurality of yarns Y on the limiting yarn guide 12. Next, the spinning control device 102 moves the front end of the spinning unit 63 toward the base end side in the axial direction of the first yarn guide roller 13 (see Fig. 9At the same time, the unit control device 101 moves the limiting yarn guide 12 from the yarn spinning position to the production position (refer to Fig. 9 Then, the yarn control device 102 moves the yarn unit 63 to sequentially hang the yarn Y on the first yarn guide roller 13 and the second yarn guide roller 14 (see Fig. 9 (f)).

[0119] In the next step S108, the threading robot 4 is used to thread the plurality of fulcrum yarn guides 21. More specifically, the threading auxiliary component 66 (see FIG. 1 ) of the threading unit 63 is used to thread the plurality of fulcrum yarn guides 21. Figure 5 (b)), the plurality of yarns Y are kept separated from each other. Next, the spinning control device 102 controls the robot arm 62 to move the spinning unit 63 to a predetermined position on the rear side (see Figure 5 In addition, the spinning control device 102 moves the spinning unit 63 diagonally forward to the left (see Figure 5 Thus, the plurality of yarns Y are hung on the corresponding fulcrum yarn guides 21 (see arrows in (b)). Fig.10 (a)).

[0120] In the next step S109, the unit control device 101 starts to move the second yarn guide roller 14 and the plurality of fulcrum yarn guides 21 toward the production position. Next, the unit control device 101 determines whether the fulcrum yarn guide 21 returns normally to the separation position (production position) within a predetermined time from the start of moving the fulcrum yarn guide 21. Specifically, in the next step S110, when the movable member 32 contacts the second limit switch 72 and the second limit switch 72 is turned on (S110: Yes), the unit control device 101 determines that the fulcrum yarn guide 21 has moved normally to the separation position. On the other hand, when the second limit switch 72 is turned off (S110: No), the unit control device 101 returns to step S110 until the predetermined time has passed (S111: No).

[0121] When the second limit switch 72 remains in the OFF state and a predetermined time has passed since the fulcrum yarn guide 21 started to move toward the separated position (S111: Yes), the unit control device 101 determines that the movement of the fulcrum yarn guide 21 toward the separated position is abnormal. Accordingly, the yarn spinning is stopped in the same manner as in step S105. Furthermore, the unit control device 101 controls the reporting unit 122 to report information indicating that the movement of the fulcrum yarn guide 21 is abnormal (S112).

[0122] On the other hand, if the second limit switch 72 is turned on before the predetermined time has passed (S110: Yes. Fig.10(b)), the unit control device 101 sends a signal indicating that the movement of the fulcrum yarn guide 21 is normal to the centralized control device 100. In addition, the unit control device 101 causes the yarn bundle guide 41 to move from the initial position (refer to Figure 6 solid line) towards the intersection (refer to Figure 6 Furthermore, the unit control device 101 moves the plurality of holding members 52 of the first separation device 42 from the first position to the second position (see Figure 7 (b) and Fig.10 (b)).

[0123] The central control device 100 sends a signal for continuing the operation of the spinning robot 4 to the spinning control device 102 based on the signal received from the unit control device 101. The spinning control device 102 operates the spinning robot 4 according to the signal. Specifically, the spinning control device 102 uses the robot arm 62 to move the spinning unit 63 and hang a plurality of silk threads Y on the silk thread bundling guide 41 (S113). As a result, each silk thread Y is arranged immediately behind the corresponding holding member 52 (refer to Figure 7 (b) and Fig.10 (b)).

[0124] In the next step S114, threading is performed on the bobbin B. Specifically, the unit control device 101 returns the holding member 52 to the first position (see Figure 7 (a) and Fig.11 ), and move the second separating device 43 toward the receiving position (refer to Figure 6 In addition, the unit control device 101 moves the first separation device 42 to the transfer position (refer to Figure 6 After the first separating device 42 is moved to the second position (dashed line), the holding component 52 is moved toward the second position again. As a result, the yarn Y is transferred from the first separating device 42 to the second separating device 43 (omitted from the figure). Then, the unit control device 101 swings the holding component 54 of the second separating device 43 from the receiving position to the left (omitted from the figure). At this time, the yarn Y is captured by the traversing yarn guide 22. In addition, the unit control device 101 temporarily detaches the yarn Y from the traversing yarn guide 22 with the help of a wire drawing device (not shown) and guides it toward the slit of the bobbin B. As a result, the yarn Y is hung on the bobbin B. Then, the unit control device 101 returns the yarn Y to the position where it was captured by the traversing yarn guide 22 with the help of the wire drawing device. When the yarn Y is captured by the traversing yarn guide 22 again, the yarn Y is finished and the winding of the yarn Y by the traction unit 3 begins (S115).

[0125] As described above, when it is determined that the movement of the fulcrum yarn guide 21 is normal, the yarn can be threaded, and when it is determined that the movement of the threading target component is abnormal, the yarn can be stopped. Therefore, it is possible to suppress the malfunction caused when the fulcrum yarn guide 21 cannot move normally.

[0126] The operation of the thread-threading robot 4 is continued only when it is determined that the movement of the fulcrum thread guide 21 is normal. Therefore, when an abnormality occurs in the movement of the fulcrum thread guide 21, it is possible to reliably prevent the thread-threading robot 4 from accidentally threading.

[0127] Furthermore, when it is determined that an abnormality has occurred in the movement of the fulcrum yarn guide 21, information indicating the occurrence of the abnormality is reported by the reporting unit 122. Therefore, when an abnormality has occurred in the movement of the fulcrum yarn guide 21, the operator can be urged to take prompt measures.

[0128] Furthermore, the position information detection unit 70 detects information on the position of the fulcrum yarn guide 21. Therefore, by using such information, it is possible to easily determine whether the movement of the fulcrum yarn guide 21 is normal.

[0129] Furthermore, by using a generally relatively inexpensive limit switch as the position information detecting section 70, it is possible to easily determine whether or not the thread-threading target component has reached the target position while suppressing an increase in the manufacturing cost of the textile machine.

[0130] Furthermore, the air cylinder 31 of the driving unit 30 generally has a smaller thrust than an electric motor, so even if the yarn scraps are only slightly accumulated, there is a concern that the fulcrum yarn guide 21 may not be able to move normally. In such a structure, it is effective to determine whether the movement of the fulcrum yarn guide 21 is normal based on the detection result detected by the position information detection unit 70.

[0131] Furthermore, the plurality of fulcrum yarn guides 21 (especially the fulcrum yarn guide 21R disposed at the rearmost side) need to move a long distance between the separated position and the approached position. Therefore, when the operation of the driving unit 30 is unstable, there is a high concern that the target position cannot be reached normally. In such a structure, it is effective to determine whether the movement of the fulcrum yarn guide 21 is normal based on the detection result detected by the position information detection unit 70.

[0132] Furthermore, when the yarn Y is wound onto the bobbin, if the plurality of fulcrum yarn guides 21 are offset from the separated position, there is a concern that the yarn Y hung on the plurality of fulcrum yarn guides 21 cannot be normally wound onto the bobbin B, and the yarn already wound onto the bobbin B may be wasted. In such a configuration, it is effective to determine whether the movement of the plurality of fulcrum yarn guides 21 toward the separated position is normal based on the detection result detected by the second limit switch 72 of the position information detection unit 70.

[0133] Furthermore, when the yarns Y are hung on the plurality of fulcrum yarn guides 21, if the plurality of fulcrum yarn guides 21 are deviated from the approach position, there is a concern that the yarns may not be normally threaded into the plurality of fulcrum yarn guides 21. In such a configuration, it is effective to determine whether the movement of the plurality of fulcrum yarn guides 21 to the approach position is normal based on the detection result detected by the first limit switch 71 of the position information detection unit 70.

[0134] Next, a modified example in which the above-described embodiment is modified will be described. However, components having the same configuration as those in the above-described embodiment are denoted by the same reference numerals and description thereof will be appropriately omitted.

[0135] (1) In the above embodiment, the unit control device 101 is configured to immediately continue the operation of the spinning robot 4 when the plurality of fulcrum yarn guides 21 normally move to the target position (separated position or approached position), but the present invention is not limited thereto. For example, the unit control device 101 may determine that the plurality of fulcrum yarn guides 21 normally move to the target position after waiting for the above-mentioned predetermined time.

[0136] (2) The position information detection unit 70 includes both the first limit switch 71 and the second limit switch 72 , but the present invention is not limited thereto. The position information detection unit 70 may include only one of the first limit switch 71 and the second limit switch 72 .

[0137] (3) The position information detection unit 70 may include, for example, an optical position sensor instead of the first limit switch 71 and the second limit switch 72. Alternatively, the position information detection unit 70 may include, for example, a camera (not shown) for capturing an image. The unit control device 101 may also perform image recognition using the image, and determine whether the plurality of fulcrum yarn guides 21 have moved normally to the target position based on the result of the image recognition.

[0138] (4) In the above embodiments, the driving unit 30 includes the cylinder 31, but the present invention is not limited to this. Fig.12As shown, the winding portion 15A may also include a driving portion 30A including an electric motor 81 provided with a rotating shaft 81a (the movable portion of the present invention) instead of the driving portion 30. The driving portion 30A is, for example, a well-known ball screw mechanism including a ball screw 83 and a nut 84. The ball screw 83 is connected to the rotating shaft 81a, for example, by means of a coupling 82, and extends in the front-to-back direction. The nut 84 is screwed with the ball screw 83. A sliding member 85 is fixed to the nut 84. The sliding member 85 is connected to the above-mentioned movable member 32 by means of a magnetic force. In addition, the winding portion 15A may also include the above-mentioned position information detection portion 70, but is not limited to this. The winding portion 15A may also include, for example, a rotary encoder 86 (the detection portion of the present invention) in addition to the position information detection portion 70 or instead of the position information detection portion 70. In other words, the electric motor 81 may also be a servo motor. The rotary encoder 86 is configured to detect information about the rotation angle of the rotating shaft 81a of the electric motor 81 (in other words, information related to the position of the rotating shaft 81a). The unit control device 101 controls the electric motor 81 so that the fulcrum yarn guide 21 moves a predetermined target distance. The unit control device 101 may also calculate the moving distance of the fulcrum yarn guide 21 using the detection result detected by the rotary encoder 86. Furthermore, the unit control device 101 may also determine whether the fulcrum yarn guide 21 has reached the target position normally by comparing the calculated moving distance with the target distance.

[0139] Here, if the yarn scraps and the like are accumulated between the rotating shaft 81a of the electric motor 81 and the fixing part (housing, etc.), there is a concern that an excessive load is applied to the electric motor 81 and the electric motor 81 may fail. In view of this point, in this modification, by stopping the operation of the electric motor 81 when it is determined that the movement of the fulcrum yarn guide 21 is abnormal, it is possible to suppress the situation where an excessive load is applied to the electric motor 81. In addition, by using information related to the rotation angle of the rotating shaft 81a (in other words, the position of the rotating shaft 81a), the position information of the fulcrum yarn guide 21 can be indirectly obtained. Thus, even if the information related to the position of the fulcrum yarn guide 21 cannot be directly obtained, it is possible to determine whether the movement of the fulcrum yarn guide 21 is normal or abnormal. In addition, a potentiometer not shown in the figure may be provided instead of the rotary encoder 86. In addition, a linear motor not shown in the figure having a movable part (not shown) that can move approximately linearly may be provided instead of the electric motor 81 having the rotating shaft 81a. In this case, a linear encoder (not shown) may be provided instead of the rotary encoder 86. The information on the position of the movable part of the linear motor may be detected by the linear encoder.

[0140] (5) As a further modification of the above (4), for example Fig.13As shown, the drive unit 30B of the winding unit 15B may also include a stepping motor 91 driven by a pulse signal as an electric motor. The stepping motor 91 may be driven, for example, by a driver 92 (detection unit of the present invention) electrically connected to the unit control device 101. The driver 92 may be configured to detect a step-out of the stepping motor 91. That is, if the load torque applied to the rotating shaft 91a of the stepping motor 91 increases, there is a concern that the rotation of the rotating shaft 91a becomes slow and the fulcrum guide 21 cannot move smoothly. In addition, generally, if the load torque applied to the rotating shaft 91a of the stepping motor 91 increases, the motor current flowing in the motor increases. Therefore, the driver 92 may detect a step-out by comparing the motor current flowing in the stepping motor 91 with the motor current in normal state, for example. The unit control device 101 may also determine whether the movement of the fulcrum guide 21 is normal or abnormal based on the detection result (detection result related to the movement of the fulcrum guide 21) detected by the driver 92. As a specific example, the unit control device 101 may send information about the target distance that the fulcrum yarn guide 21 should move to the driver 92. The driver 92 sends the required number of pulse signals to the stepping motor 91 based on the information about the target distance. Furthermore, the unit control device 101 may determine that the movement of the fulcrum yarn guide 21 is abnormal when a predetermined number of out-of-steps occur. In this case, the unit control device 101 may determine that the movement of the fulcrum yarn guide 21 is abnormal before a predetermined time has passed since the fulcrum yarn guide 21 was started to move. Alternatively, the unit control device 101 may determine that the movement of the fulcrum yarn guide 21 is abnormal when out-of-steps are detected when the last pulse signal is sent from the driver 92 to the stepping motor 91. Alternatively, the unit control device 101 may store the upper limit value of the motor current and immediately determine that the movement of the fulcrum yarn guide 21 is abnormal when the motor current flowing through the stepping motor 91 exceeds the upper limit value.

[0141] By doing so, even when the information related to the position of the fulcrum yarn guide 21 cannot be obtained, it is possible to determine whether the movement of the fulcrum yarn guide 21 is normal or abnormal. In addition, the driver 92 may detect the step-out as described above, but is not limited to this. For example, the unit control device 101 may store the information of the motor current in normal state in advance, and detect the step-out by comparing the actual motor current with the motor current in normal state. In this case, the unit control device 101 is equivalent to the detection unit of the present invention.

[0142] (6) As described above, the limit switch may be, for example, a non-contact proximity sensor. Fig.14 (a) and (b) are specifically described. Fig.14As shown in (a) and (b), the position information detection unit 70C of the winding portion 15C has a first limit switch 71C and a second limit switch 72C instead of the above-mentioned first limit switch 71 and the second limit switch 72. The first limit switch 71C and the second limit switch 72C can be, for example, well-known magnetic proximity sensors that use electromagnetic induction to detect the approach of conductive parts such as metal bodies, but are not limited to this. In addition, a metal plate 73 extending in the front-to-back direction can be fixed to the movable part 32, for example, at the lower end portion. The first limit switch 71C and the second limit switch 72C are arranged outside the moving range of the metal plate 73 to avoid interference with the metal plate 73. The first limit switch 71C and the second limit switch 72C, for example, Fig.14 As shown in (a) and (b), the first limit switch 73 may be arranged at a position lower than the metal plate 73. That is, for example, the first limit switch 73 may be arranged such that when the plurality of fulcrum guides 21 are in the close position, the metal plate 73 is located directly above the first limit switch 71C (see Fig.14 (a)). The second limit switch 72c may be configured such that when the plurality of fulcrum yarn guides 21 are located at the separated positions, the metal plate 73 is located directly above the second limit switch 72c (see Fig.14 (b)). The unit control device 101 may determine whether the movement of the fulcrum yarn guide 21 is normal or abnormal based on the detection result detected by the position information detection unit 70C.

[0143] (7) When an abnormality occurs in the movement of the fulcrum yarn guide 21, it is not necessary to issue a report by the reporting unit 122. When an abnormality occurs in the movement of the fulcrum yarn guide 21, the unit control device 101 may stop only the operation of the traction unit 3, for example.

[0144] (8) When an abnormality occurs in the movement of the fulcrum yarn guide 21, the yarn spinning does not necessarily have to be stopped immediately. For example, the unit control device 101 may return the fulcrum yarn guide 21 to its original position (one of the separated position and the approached position) when an abnormality occurs in the movement of the fulcrum yarn guide 21, and then start moving the fulcrum yarn guide 21 toward the target position (the other of the separated position and the approached position) again.

[0145] (9) In the above-mentioned embodiment, the position information detection unit 70 and other detection units detect information related to the movement of the fulcrum yarn guide 21, but the present invention is not limited to this. A detection unit may also be provided to detect information related to the movement of other yarn threading object components (such as the limiting yarn guide 12, the second yarn guide roller 14, and the holding member 52) on which the yarn Y is hung.

[0146] (10) The spinning pull-up machine 1 does not necessarily need to include the spinning robot 4. The spinning pull-up machine 1 may be configured so that at least a part of the spinning operation is performed by an operator.

[0147] (11) The above-mentioned air cylinder 31 does not necessarily need to be housed inside the yarn guide support body 26. Furthermore, the slider 35 and the movable member 32 may be connected to each other by means other than magnets (for example, a fastener such as a screw).

[0148] (12) In the above embodiments, the unit control device 101 and the spinning control device 102 communicate indirectly via the central control device 100, but the present invention is not limited to this. The unit control device 101 and the spinning control device 102 may communicate directly.

[0149] (13) In the embodiments up to the above-mentioned embodiment, the centralized control device 100, the unit control device 101, and the spinning control device 102 together correspond to the control unit of the present invention, but the present invention is not limited thereto. For example, the above-mentioned unit control device 101 and the spinning control device 102 are not necessarily provided. The centralized control device 100 may also control the traction unit 3 and the spinning robot 4. In this case, the centralized control device 100 corresponds to the control unit of the present invention.

[0150] (14) The spinning traction machine 1 described above includes a plurality of traction units 3, but the present invention is not limited thereto and only one traction unit 3 may be provided.

[0151] (15) In the embodiments up to the above-mentioned embodiments, in the initial state before the spinning starts, the plurality of silk threads Y are sucked and held by the silk aspirator 11, but the invention is not limited thereto. For example, a silk thread lowering device (not shown) that holds the plurality of silk threads Y spun from the spinning device 2 and lowers them downwards may be provided near the spinning device 2 (for example, see Japanese Patent Application Publication No. 2017-82376). The spinning robot 4 can directly obtain the silk threads Y from the silk thread lowering device when spinning.

[0152] (16) The detection unit for detecting information related to the movement of the spinning object component is not limited to the spinning traction machine 1, and can be provided in various fiber machines that process at least one silk thread. For example, in the false twisting machine (fiber machine) described in Japanese Patent Publication No. 2016-223034, the spinning object component for hanging the silk thread can be moved between the production position and the spinning position. Furthermore, the detection unit can also be provided in the false twisting machine.
