It is characterized in that the separating roller can be moved between the roller retracted position and the roller contact position by rotating about the shaft.

In order to allow the separating roller to move between the roller retracted position and the roller contact position, the roller support may be configured to be linearly movable, for example. However, in general, a device for linearly moving a member has a long movable part that slides and a fixed part whose position is fixed. A gap is formed. Therefore, when a plurality of running yarns come into contact with the separating roller, the angle of the movable portion with respect to the fixed portion may change slightly. Since the movable part is long, even if the angle changes only slightly, the positions of the roller support part and the separating roller can change greatly. As a result, the position of the separating roller may be greatly deviated from the target position. For this reason, the relative positions of the plurality of threads and the pair of holding portions are largely displaced, which may cause a problem that the plurality of threads cannot be normally held by the pair of holding portions.

In this regard, in the present invention, the roller support portion is configured to be rotatable around the rotation shaft. That is, the separating roller can be moved by integrally rotating the roller supporting portion with the rotating shaft. For this reason, compared with a configuration in which the roller support portion is linearly moved, it is possible to suppress positional fluctuations of the roller support portion and the separating roller as described above. Therefore, the positional accuracy of the separating roller can be improved.

In the present invention, when viewed from the direction in which the pivot shaft extends, the separating roller looks like a circle (that is, the separating roller looks compact). Therefore, compared to the case where the direction in which the rotating shaft extends and the direction in which the rotating shaft of the separating roller extends are not aligned, the movement area of the separating roller can be made compact. Therefore, it is possible to effectively prevent the separating roller from interfering with other members.

A plurality of guide units 15 are mounted on a guide support 18 and configured to be movable in the front-rear direction. A plurality of guide units 15 are provided corresponding to the plurality of bobbins B, respectively, and arranged along the front-rear direction. Each of the plurality of guide units 15 has a main body 19 and a fulcrum guide 20 (yarn guide of the present invention). Body 19 is movably mounted on guide support 18 . The fulcrum guide 20 is fixed to the main body 19 and serves as a fulcrum when the yarn Y is traversed by the traverse guides 16 . A plurality of fulcrum guides 20 (fulcrum guides 20A) of the winding section 5A are fixed to the right end of the main body 19. As shown in FIG. A plurality of fulcrum guides 20 (fulcrum guides 20B) included in the winding section 5B are fixed to the left end of the main body 19 . For further details of the plurality of guide units 15, see, for example, JP-A-2017-114573 mentioned above.

The plurality of guide units 15 (that is, the plurality of fulcrum guides 20) are positioned closer to each other in the front-rear direction than the winding position (separate position; see FIG. 2) when the yarn Y is wound on the bobbin B and the separated position. It is configured to be movable between the adjacent position (see FIG. 3). More specifically, for example, guide units 15 adjacent to each other in the front-rear direction are connected to each other by a belt (not shown). The rearmost guide unit 15 is movable in the front-rear direction by, for example, a linear slider (not shown). By operating the linear sliders, the plurality of guide units 15 can move between a spaced position spaced apart from each other and a close position gathered on the front side compared to the spaced position. As will be described later, threading to the plurality of fulcrum guides 20 is performed when the plurality of fulcrum guides 20 are positioned at the close position.

A plurality of traverse guides 16 are arranged side by side in the front-rear direction. Each of the plurality of traverse guides 16 is driven by, for example, a traverse motor (not shown) to traverse the corresponding yarn Y in the front-rear direction. The contact roller 17 is a roller whose rotating shaft direction is substantially parallel to the front-rear direction, and is arranged just above the upper bobbin holder 13 . The contact rollers 17 contact the surfaces of the plurality of packages P supported by the bobbin holder 13 on the upper side to apply contact pressure to the surfaces of the packages P to shape the packages P. As shown in FIG.

In each of the pair of winding units 5 configured as described above, when the upper bobbin holder 13 is rotationally driven, the yarn Y traversed by the traverse guide 16 is wound around the bobbin B, and the package P is formed. be. Further, when the package P is fully wound, the upper and lower positions of the two bobbin holders 13 are exchanged by rotating the turret 12 . As a result, the bobbin holder 13 positioned on the lower side moves upward, and the package P can be formed by winding the yarn Y around the bobbin B attached to the bobbin holder 13 . Also, the bobbin holder 13 on which the fully wound package P is mounted moves downward. The full package P is recovered, for example, by a package recovery device (not shown).

Here, generally, as a preparatory work for winding a plurality of yarns Y onto a plurality of bobbins B, it is necessary to thread the yarn on the take-up machine 1 . Conventionally, an operator manually hooks a thread using a known thread hooking member (see, for example, Japanese Patent Application Laid-Open No. 2017-114573) for the plurality of fulcrum guides 20 of the pair of winding units 5 as described above. has been done. However, if the threading is performed manually, the time required to complete the threading may vary greatly depending on the operator's skill level. If threading takes too much time, problems such as increased production loss occur. Therefore, in order to improve the efficiency of threading when threading a plurality of fulcrum guides of the pair of winding units 5, the take-up machine 1 of the present embodiment has the following configuration (described later). It has a yarn hooking mechanism 30).

FIG. 8(a) is a side view of the yarn spacing increasing portion 34 (described later). FIG. 8(b) is a view in the direction of arrow VIII(b) of FIG. 8(a).

The yarn hooking mechanism 30 includes a pair of holding portions 31 (see FIG. 4A etc.), a driving mechanism 32 (see FIG. 4A etc.), an adjusting portion 33 (see FIG. 7A etc.), and a thread interval increasing portion 34 (see FIG. 8(a), etc.). As an overview, the yarn hooking mechanism 30 moves the pair of holding parts 31 by the drive mechanism 32 in a state in which the pair of holding parts 31 hold the plurality of yarns Y, thereby spinning the plurality of yarns Y without manual operation. fulcrum guides 20, respectively. Further, the adjusting portion 33 and the yarn interval increasing portion 34 are configured to be assisted when the pair of holding portions 31 are caused to respectively catch the plurality of yarns Y. As shown in FIG. Details will be described below.

(Holding part)
The pair of holding portions 31 (holding portions 31A and 31B) are configured to separate and hold a plurality of running yarns Y, respectively. As shown in FIG. 4A, the holding portion 31A (the first holding portion of the present invention) and the holding portion 31B (the second holding portion of the present invention) are configured substantially bilaterally symmetrical to each other. The left holding portion 31A is configured to hold a plurality of yarns YA (see FIG. 1). The holding portion 31B arranged on the right side is configured to hold a plurality of yarns YB (see FIG. 1).

The holding portion 31A is attached to the winding portion 5A via a driving portion 32A (described later) of the driving mechanism 32. As shown in FIG. More specifically, a support member 35 whose position is fixed between the support frame 11 of the winding section 5A and the guide support 18 in the vertical direction (see FIGS. 3, 4A and 4B). support member 35A shown) is provided. The support member 35 has, for example, a rod member 36 extending in the front-rear direction and a plate member 37 fixed to the front portion of the rod member 36 . The holding portion 31A is attached to the support member 35A via the driving portion 32A. Similarly, the holding part 31B is connected to the supporting member 35 of the winding part 5B (refer to the supporting member 35B shown in FIGS. 3, 4A and 4C) via the driving part 32B (described later) of the driving mechanism 32. ). The vertical position of the support member 35A (the first support member of the present invention) is, for example, about 5 mm lower than the vertical position of the support member 35B (the second support member of the present invention). About 5 mm is, for example, a value larger than the thickness of the comb guide 41, which will be described later.

As shown in FIG. 5A, the holding portion 31A has a comb guide 41 and an intervening member 42. As shown in FIG. The comb guide 41 is a substantially comb-shaped flat plate member. The comb guide 41 has a body portion 43 and a connection portion 44 . A plurality of holding grooves 45 for holding a plurality of yarns Y one by one are formed in the body portion 43 . The plurality of holding grooves 45 are arranged side by side at least in the left-right direction. The inlet of each holding groove 45 is formed at the rear end portion of the body portion 43 . The distance between the entrances of the plurality of holding grooves 45 in the direction in which the plurality of holding grooves 45 are arranged is substantially equal to the distance (predetermined distance) between the plurality of yarns Y defined by the regulating guide 8 in the horizontal direction. A through hole 46 extending in the left-right direction and penetrating in the up-down direction, for example, is formed in an intermediate portion of the main body 43 in the front-rear direction. Thereby, for example, a handle portion 47 that can be held by an operator is formed at the front end portion of the main body portion 43 .

The connection portion 44 of the holding portion 31A is a portion connected to the left end portion of the rear end portion of the main body portion 43 . The connection portion 44 is connected to the interposed member 42 via a swing shaft 48 whose axial direction is the vertical direction. This allows the comb guide 41 to swing with respect to the interposed member 42 . The connection portion 44 is formed with adjustment holes 49 and 50 that penetrate vertically and extend in the circumferential direction of the swing shaft 48 , for example.

As shown in FIG. 5C, a downwardly extending pin 57 is fixed to the lower end of the connecting portion 44 . The pin 57 is a member that is guided diagonally rightward (that is, at least forward) by a guide 53 described below when the holding portion 31A is moved (described later). As shown in FIG. 5A, a guide 53 made of sheet metal, for example, is attached to the right side surface of the support member 35A near the front end. The guide 53 has a root portion 54 extending upward from the support member 35A and a guide portion 55 extending rightward from the upper end portion of the root portion 54 . The guide portion 55 is formed with a guide surface 56 facing obliquely forward left and extending obliquely forward right, for example. The vertical position of the guide surface 56 and the vertical position of the pin 57 at least partially overlap. The guide surface 56 is arranged on a track along which the pin 57 is moved by the driving portion 32A.

The intervening member 42 is, for example, a substantially L-shaped member when viewed from above and below. The intervening member 42 is arranged below the comb guide 41 . The intervening member 42 swingably supports the comb guide 41 via a swing shaft 48 . The intervening member 42 has, for example, bolt holes 51 and 52 penetrating vertically. The bolt holes 51 are provided at positions corresponding to the adjustment holes 49 . A headed bolt (not shown) is threaded through the adjustment hole 49 and into the bolt hole 51 . The bolt holes 52 are provided at positions corresponding to the adjustment holes 50 . A similar bolt (not shown) is threaded through adjustment hole 50 and into bolt hole 52 . The comb guide 41 is fixed to the interposed member 42 when the heads of these bolts press the comb guide 41 from above. Note that the position of the comb guide 41 with respect to the interposed member 42 may be adjusted when these bolts are loosened. The intervening member 42 is fixed to a support arm 61A (described later) of the driving portion 32A.

As shown in FIG. 5(b), the holding portion 31B also has a comb guide 41 and an intervening member 42, like the holding portion 31A. The holding portion 31B is arranged on the right side of the holding portion 31A and configured symmetrically with the holding portion 31A. Further description of the holding portion 31B is omitted.

(drive mechanism)
The drive mechanism 32 is configured to drive the pair of holding portions 31 to move. As shown in FIG. 4A, the drive mechanism 32 has a drive section 32A that drives and moves the holding section 31A, and a drive section 32B that drives and moves the holding section 31B. The driving section 32A and the driving section 32B are configured to be operable independently of each other. Below, 32 A of drive parts are demonstrated in detail. 4A to 4C show a state in which the pair of holding portions 31 are positioned at a position (holding portion retracted position) when threading is not performed.

The drive section 32A is attached to the support member 35A of the winding section 5A. As shown in FIG. 4A, the driving portion 32A includes a support arm 61A, a guide rail 62A (first guide rail of the present invention), a swing arm 63A, and a linear slider 64A (first holding rail of the present invention). and an air cylinder 65A (first rail driving portion of the present invention). As an overview, the support arm 61A to which the holding portion 31A is attached moves at least in the front-rear direction along the guide rail 62A by the operation of the linear slider 64A. The guide rail 62A swings integrally with the swing arm 63A by the operation of the air cylinder 65A, thereby switching the directions in which the support arm 61A and the holding portion 31A move.

The support arm 61A is an elongated member extending at least in the front-rear direction. A holding portion 31A is fixed to the front end portion of the support arm 61A. A sliding portion 71 that can slide along the guide rail 62A is provided at the front end of the support arm 61A. The sliding portion 71 may be, for example, a pin extending vertically. The sliding portion 71 can move following the guide rail 62A when the guide rail 62A swings. A through hole 72 penetrating vertically is formed in the rear end portion of the support arm 61A (see FIGS. 4A and 7A). The through hole 72 extends slightly long in the front-rear direction. A rear end portion of the support arm 61A is attached to a slider 82 (described later) of the linear slider 64A via a pin 73 extending vertically and inserted through the through hole 72 so as to be capable of swinging. As a result, the support arm 61A can swing with respect to the slider 82 and can move somewhat in the front-rear direction. That is, the support arm 61A is positioned relative to the slider 82 at a predetermined arm front position (second slide position of the present invention) and an arm rear position (first slide position of the present invention) on the rear side of the arm front position. It is possible to move between In other words, the support arm 61A supports the holding portion 31A so as to be slidable at least in the front-rear direction. Support arm 61A is included in the slide portion of the present invention.

The guide rail 62A is a substantially linear rail extending at least in the front-rear direction. The guide rail 62A is arranged to guide the support arm 61A at least in the front-rear direction. The guide rail 62A engages with a sliding portion 71 provided on the support arm 61A. The guide rail 62A is fixed to the right end of the swing arm 63A by a fixture (eg, bolt and nut) not shown. Alternatively, the guide rail 62A may be integrally formed with the swing arm 63A by welding or the like.

The swing arm 63A is, for example, a plate-shaped arm extending at least in the front-rear direction. For example, as shown in FIG. 4(a), the swing arm 63A is arranged at the front side portion of the drive section 32A. A rear end portion of the swing arm 63A is connected to the support member 35A via a swing shaft 75 whose axial direction is the vertical direction. Thereby, the swing arm 63A can swing integrally with the guide rail 62A. A guide hole 76 extending at least in the front-rear direction is formed through the swing arm 63A in the vertical direction. A pin 86 attached to an air cylinder 65A, which will be described later, is inserted through the guide hole 76 . A guide hole 76 formed in the swing arm 63A extends leftward toward the front side.

When the direction orthogonal to the direction in which the guide hole 76 extends is defined as the orthogonal direction, the size of the portion of the guide hole 76 other than the front end portion (hereinafter referred to as width) in the orthogonal direction is only slightly larger than the outer diameter of the pin 86. to big. This allows the pin 86 to move along the direction in which the guide hole 76 extends. Further, as shown in FIG. 7A, the width of the guide hole 76 at the front end of the guide hole 76 is slightly larger than the outer diameter of the pin 86 (specifically, approximately 5 mm larger). In other words, a play portion 77 is provided at the front end of the guide hole 76 to allow the swing arm 63A to swing freely with respect to the pin 86 (the reason will be described later).

The linear slider 64A is a device for moving the support arm 61A in the front-rear direction. The linear slider 64A is, for example, a known rodless cylinder operated by compressed air. The linear slider 64A has a cylinder body 81 (cylinder body 81A) and a slider 82 . The cylinder main body 81A (first main body of the present invention) extends in the front-rear direction. The cylinder main body 81A is fixed to the rear portion of the support member 35A by, for example, a fixture (not shown). That is, the cylinder main body 81A is provided integrally with the support member 35A. Alternatively, the cylinder body 81A may be welded to the support member 35A, for example. The slider 82 is configured to be slidable in the front-rear direction along the cylinder body 81 . A support arm 61A is attached to the slider 82 so as to be able to swing. The slider 82 can move between the vicinity of the front end portion and the vicinity of the rear end portion of the cylinder body 81 by supplying compressed air to the cylinder body 81 and discharging compressed air from the cylinder body 81 . As a more specific example, as shown in FIG. 6A, the cylinder body 81 is formed with a piston chamber 81F arranged on the front side of the slider 82 and a piston chamber 81R arranged on the rear side of the slider 82. ing. The piston chamber 81F is connected to a compressed air supply port Ps and an exhaust port Pe2 via an electromagnetic valve EV1, which is, for example, a known five-way electromagnetic valve. The piston chamber 81R is connected to the supply port Ps and the discharge port Pe1 via the solenoid valve EV1. Electromagnetic valve EV1 is electrically connected to control device 6 . The control device 6 controls the solenoid valve EV1 to control the supply and discharge of compressed air. Compressed air is supplied from the supply port Ps to the piston chamber 81F and discharged from the piston chamber 81R to the discharge port Pe1, whereby the slider 82 moves rearward. Compressed air is supplied from the supply port Ps to the piston chamber 81R and discharged from the piston chamber 81F to the discharge port Pe2, thereby moving the slider 82 forward. Instead of the linear slider 64A, another cylinder mechanism driven by fluid such as compressed air, or an electric drive mechanism (for example, a ball screw mechanism or a rack and pinion mechanism) may be provided.

The air cylinder 65A is a device for swinging the swing arm 63A and the guide rail 62A. The air cylinder 65A has a cylinder body 83 and a piston rod 84. As shown in FIG. The cylinder body 83 extends in the front-rear direction. The cylinder body 83 is attached to the front portion of the support member 35A. The piston rod 84 extends rearward from the rear end of the cylinder body 83, for example. The piston rod 84 can be expanded and contracted by supplying compressed air to the cylinder body 83 and discharging compressed air from the cylinder body 83 . As a more specific example, as shown in FIG. 6B, the cylinder body 83 has a piston chamber 83F formed on the front side and a piston chamber 83R formed on the rear side. The piston chamber 83F is connected to a compressed air supply port Ps and a compressed air discharge port Pe2 via an electromagnetic valve EV2 having the same configuration as the five-way electromagnetic valve described above. The piston chamber 83R is connected to the supply port Ps and the discharge port Pe1 via the electromagnetic valve EV2. Compressed air is supplied from the supply port Ps to the piston chamber 83F and discharged from the piston chamber 83R to the discharge port Pe1, whereby the piston rod 84 moves rearward. Compressed air is supplied from the supply port Ps to the piston chamber 83R and discharged from the piston chamber 83F to the discharge port Pe2, whereby the piston rod 84 moves rearward. A pin 86 extending upward is provided at the upper end of a rod end 85 attached to the tip of the piston rod 84 (see FIGS. 4(a), 10(b), etc.). The pin 86 is inserted through the guide hole 76 of the swing arm 63A. A disk member 87 having a diameter larger than that of the pin 86 is attached to the upper end of the pin 86 to prevent the pin 86 from coming off the guide hole 76 . Instead of the air cylinder 65A, another cylinder mechanism driven by fluid or an electric drive mechanism (for example, a ball screw mechanism or a rack and pinion mechanism) may be provided.

The driving portion 32B is attached to the support member 35B of the winding portion 5B. As shown in FIG. 4A, the drive section 32B includes a support arm 61B, a guide rail 62B (second guide rail of the present invention), a swing arm 63B, and a linear slider 64B, similarly to the drive section 32A. (the second holding portion driving portion of the present invention) and an air cylinder 65B (the second rail driving portion of the present invention). The support arm 61B supports the holding portion 31B so as to be slidable at least in the front-rear direction. The support arm 61B is included in the slide portion of the present invention together with the support arm 61A. The linear slider 64B has the same configuration as the linear slider 64A, and operates independently from the linear slider 64A by means of compressed air. The air cylinder 65B has a configuration similar to that of the air cylinder 65A, and operates independently of the air cylinder 65A with compressed air. The cylinder body 81 (cylinder body 81B) of the linear slider 64B is fixed to the rear portion of the support member 35B by, for example, a fixture (not shown) (that is, provided integrally with the support member 35B). The cylinder main body 81B corresponds to the second main body of the invention. Since the drive section 32B is configured symmetrically with the drive section 32A, further detailed description of the drive section 32B will be omitted.

For both the linear sliders 64A and 64B described above, the position near the front end of the cylinder body 81 (see solid lines in FIGS. 4B and 4C) is called the "front end position" for convenience of later explanation. A position near the rear end of the cylinder body 81 (see two-dot chain lines in FIGS. 4B and 4C) is called a "rear end position."

For both the air cylinders 65A and 65B described above, the positions of the rod end 85 and the pin 86 when the piston rod 84 is extended (see solid lines in FIGS. 4B and 4C) are shown as " called the "extended position". Further, the positions of the rod end 85 and the pin 86 when the piston rod 84 is contracted (see two-dot chain lines in FIGS. 4(b) and (c)) are called "contracted position".

(Regulator)
The adjustment section 33 is configured to allow the operator to finely adjust the positions of the pair of holding sections 31 during threading. As shown in FIGS. 7(a) and 7(b), the adjusting section 33 is provided on both the drive sections 32A and 32B. The adjustment portion 33 (adjustment portion 33A) of the drive portion 32A has the swing arm 63A described above. More specifically, the adjustment portion 33A has a play portion 77 of a guide hole 76 provided in the swing arm 63A. The adjustment portion 33A is configured to perform its function when the pin 86 provided on the air cylinder 65A is positioned at the retracted position (details will be described later). Similarly, the adjustment portion 33 (adjustment portion 33B) of the driving portion 32B has the swing arm 63B described above.

(Increased thread spacing)
The yarn interval increasing portion 34 increases the interval in the horizontal direction between the plurality of yarns Y on the downstream side of the second godet roller 4 in the yarn traveling direction (in other words, the downstream side of the regulation guide 8 in the yarn traveling direction) during yarn hooking. It is intended to expand As shown in FIG. 8A, for example, in the winding section 5A arranged on the left side of the pair of winding sections 5, a frame 90 whose position is fixed is provided above the guide support 18. there is The thread interval increasing portion 34 is provided on the frame 90 . The yarn interval increasing section 34 has a rotating arm 91 (roller supporting section of the present invention), a handle section 92 and a separating roller 93 .

The rotating arm 91 is, for example, a substantially L-shaped member when viewed in the horizontal direction (see FIG. 8A). The rotating arm 91 is attached to the frame 90 via a rotating shaft 94 extending in the left-right direction. As a result, the rotating arm 91 can rotate around the rotating shaft 94 . When viewed in the horizontal direction, the rotating arm 91 is positioned, for example, behind the first godet roller 3 (see FIG. 8A). Further, the rotating arm 91 is positioned, for example, below the second godet roller 4 (see FIG. 8A) positioned at the front side position.

The handle portion 92 is a portion that the operator holds by hand when rotating the rotating arm 91 . For example, as shown in FIG. 8B, the handle portion 92 extends at least rightward from the base end portion of the rotating arm 91 .

The separating roller 93 is a roller rotatably attached to the tip of the rotating arm 91 . The separating roller 93 is cantilevered by the rotating arm 91 . The rotating shaft of the separating roller 93 extends along the left-right direction. That is, the direction in which the rotating shaft 94 extends and the direction in which the rotating shaft of the separating roller 93 extends are substantially the same. The separating roller has a peripheral surface 93a that can come into contact with a plurality of yarns Y. As shown in FIG. When the plurality of running yarns Y are in contact with the peripheral surface 93a, the separating roller 93 is driven to rotate by the frictional force acting between the plurality of yarns Y and the surrounding surface 93a.

By rotating the rotating arm 91 by the operator, the separating roller 93 can move between a predetermined roller retraction position and a roller contact position. More specifically, for example, a position near the first godet roller 3 (see the two-dot chain line in FIG. 8A) is the roller retraction position. The position directly below the second godet roller 4 (see the solid line in FIG. 8A) is the roller contact position. The separating roller 93 is arranged at substantially the same position as the regulation guide 8 and the second godet roller 4 in the left-right direction at least when positioned at the roller contact position.

(Threading method)
Next, a method for hooking the yarn Y on the plurality of fulcrum guides 20 using the yarn hooking mechanism 30 described above will be described with reference to FIGS. 9(a) to 18. FIG.

FIG. 16(b) is a reference diagram. 17A to 17C are explanatory diagrams showing movement of the holding portion 31A to the thread hooking completion position. FIG. 18 is an explanatory diagram showing how a plurality of yarns Y are respectively hung on a plurality of fulcrum guides 20. As shown in FIG. In FIGS. 10A to 18, only the holding portion 31A is shown representatively.

The outline of threading described in this embodiment is as follows. First, the yarn Y is passed over the first godet roller 3, the regulating guide 8 and the second godet roller 4 by the operator. Next, the operator temporarily presses the yarn Y against the separating roller 93 . Furthermore, the plurality of yarns Y are held by the pair of holding portions 31 by the operation of the yarn hooking mechanism 30 (partially including work by the operator). Finally, the plurality of yarns Y held by the pair of holding portions 31 are respectively hung on the plurality of fulcrum guides 20 by the operation of the yarn hooking mechanism 30 .

Details of threading will be described below. Before threading is started, the piston rods 84 of the air cylinders 65A and 65B are positioned at the above-described extended position (see FIG. 10(b)). The sliders 82 of the linear sliders 64A and 64B are positioned at the front end positions (see FIG. 10(c)). Thereby, each of the pair of holding portions 31 is positioned at a predetermined holding portion retracted position (see FIGS. 4A and 10A). Further, the separating roller 93 is located at the roller retracted position (see the two-dot chain line in FIG. 8(a)). Also, the support arms 61A and 61B are located at the arm rear side position.

When starting threading, the operator performs a predetermined input operation on the input section (not shown) of the control device 6 . The control device 6 controls each part of the take-up machine 1 according to the input signal, and brings the take-up machine 1 into the following ready-for-yarn-threading state. That is, the control device 6 moves the second godet roller 4 to the front position (see FIG. 9A). At this time, the control device 6 functions as the second control section of the present invention. Further, the control device 6 moves the plurality of fulcrum guides 20 to the close position (see FIG. 3).

Next, the operator operates the handle portion 92 of the yarn interval increasing portion 34 to rotate the rotating arm 91, and moves the separating roller 93 from the roller retracted position to the roller contact position (the solid line and the figure in FIG. 8A). 9(a)).

Next, the operator uses a suction gun SG (see FIG. 9A) configured to be capable of sucking and holding a plurality of yarns Y to pick up a plurality of yarns Y (specifically, 32 yarns YA and YB). all) are aspirated and held. The operator operates the suction gun SG to hook a plurality of yarns Y on the first godet roller 3, the regulation guide 8 and the second godet roller 4 in this order (see FIG. 9(a)).

Next, the operator operates the suction gun SG to move the tip of the suction gun SG to the lower side and right side of the fiber separating roller 93 (see FIGS. 9(b) and 9(c)). The yarn Y is moved immediately behind the separating roller 93 (see FIG. 9(d)). At this time, the distance between the plurality of yarns Y traveling from the regulating guide 8 toward the suction gun SG becomes narrower as it approaches the suction gun SG.

Next, the operator moves the tip of the suction gun SG forward to bring the plurality of yarns Y into contact with the peripheral surface 93a of the separating roller 93 (see FIGS. 9(e) and 9(f)). As a result, the separating roller 93 is driven to rotate by the frictional force with the plurality of yarns Y running. At this time, the horizontal spacing of the plurality of yarns Y in contact with the separating roller 93 is widened to the same extent as the horizontal spacing of the plurality of yarns Y defined by the regulation guide 8 (see FIG. 9 ( f) see). As a result, a plurality of substantially parallel yarn paths arranged in the left-right direction are formed. This is because the interval between the plurality of yarns Y in contact with the rotating roller is generally equal to the interval defined immediately upstream of the roller in the yarn traveling direction. For details of the principle, see, for example, Japanese Patent Application Laid-Open No. 2012-021240.

After the spacing between the plurality of yarns Y is widened by the separating roller 93 , the operator performs an input operation on the input section of the control device 6 to start the operation of the yarn hooking mechanism 30 . The control device 6 controls each part of the yarn hooking mechanism 30 according to the input signal. At this time, the control device 6 functions as the first control section of the present invention. Below, the operation of the holding portion 31A and the driving portion 32A will be mainly described, and detailed explanation of the operation of the holding portion 31B and the driving portion 32B will be omitted. Simply put, in this embodiment, the control device 6 controls the driving section 32B and the driving section 32A substantially simultaneously. As a result, the holding portion 31B and the driving portion 32B operate symmetrically and substantially simultaneously with the holding portion 31A and the driving portion 32A.

First, the control device 6 controls the operation of the air cylinder 65A to move the piston rod 84 from the extended position (see FIG. 10(b)) to the retracted position (see FIG. 11(b)). As a result, when the pin 86 moves forward, the swing arm 63A and the guide rail 62A swing counterclockwise so that the guide hole 76 of the swing arm 63A follows the pin 86 (FIG. 11). (a)). Then, the front end portion of the support arm 61A and the holding portion 31A swing rightward following the guide rail 62A (see FIG. 11(a)). As a result, the holding portion 31A begins to move from the holding portion retracted position to the vicinity of a catching position (described later) where a plurality of yarns YA can be caught (see the rightward arrow in FIG. 11(a)). Here, as described above, the guide 53 is attached to the support member 35 (see region R1 in FIG. 11A and its enlarged view). A guide portion 55 (more specifically, a guide surface 56 ) of the guide 53 is arranged on a movement track of a pin 57 provided on the comb guide 41 . Therefore, since the pin 57 moves while contacting the guide surface 56, the comb guide 41 moving from the holding portion retracted position is guided at least forward along the guide surface 56 (see FIG. 11A). , see arrows in the enlarged view of region R1). Further, as the comb guide 41 is guided forward, the support arm 61A to which the holding portion 31A is attached moves to the arm front position (see the arrow pointing diagonally forward on the right side of the page in FIG. 11(a)). As a result, the holding portion 31A moves from the holding portion retracted position to the catching preparation position for the operator to make the holding portion 31A catch the plurality of yarns YA. The capture preparation position is a position at least forward of the capture position. Although illustration is omitted, the capture preparation position of the holding part 31A is a position immediately above the left portion of the separating roller 93 and immediately in front of the plurality of yarns YA. Further, when the holding portion 31A is moved from the holding portion retracted position to the catching preparation position, the holding portion 31B is moved from the holding portion retracted position to the catching preparation position for the operator to perform the work of catching the yarn YB. . Although illustration is omitted, the catching preparation position of the holding part 31B is a position immediately above the right side portion of the separating roller 93 and immediately in front of the plurality of yarns YB. The capture preparation position of the pair of holding parts 31 is a position between the second godet roller 4 and the separating roller 93 in the vertical direction. In other words, the capture preparation positions of the pair of holding portions 31 are positions downstream of the second godet roller 4 and upstream of the separating roller 93 in the yarn traveling direction. The control device 6 temporarily stops the operation of the yarn hooking mechanism 30 in this state.

Next, the operator operates the adjusting sections 33A and 33B as follows to finely adjust the positions of the holding sections 31A and 31B positioned at the capture preparation positions within a predetermined adjustment area. , the yarn YA is caught by the holding portion 31A, and the yarn YB is caught by the holding portion 31B. The adjustment zone is the zone that includes the capture ready position and the capture position.

As described above, the swing arms 63A and 63B are provided with guide holes 76, respectively. The width of the guide hole 76 other than the front end is slightly larger than the outer diameter of the pin 86 . Therefore, when the pin 86 is inserted through a portion other than the front end portion of the guide hole 76, it is almost impossible to manually swing the swing arms 63A and 63B. On the other hand, a play portion 77 is provided at the front end portion of the guide hole 76 . Therefore, when the pin 86 is inserted through the front end of the guide hole 76 (that is, when the piston rod 84 is in the retracted position), the pin 86 is loosely fitted in the play portion 77 . Therefore, the operator can manually swing the swing arms 63A and 63B in the horizontal direction (see FIGS. 12A and 12B). Also, the operator can move the support arms 61A, 61B between the front arm position and the rear arm position, as described above. That is, the support arms 61A and 61B corresponding to the slide portion of the present invention are also included in the adjusting portion of the present invention. The operator manually moves the holding portions 31A and 31B within the adjustment area, moves the holding portions 31A and 31B from the catching preparation position to the catching position, and moves the plurality of yarns Y to the holding portions 31A and 31B. It can be captured in each holding groove 45 (see FIG. 13). The operator moves the comb guide 41 by holding the handle portion 47 by hand, for example.

Here, the holding portion retracted position of the holding portion 31A is called a first holding portion retracted position, and the catching position of the holding portion 31A is called a first catching position. Further, the holding portion retracted position of the holding portion 31B is called a second holding portion retracted position, and the catching position of the holding portion 31B is called a second catching position. In the left-right direction, the distance between the first catching position and the second catching position is shorter than the distance between the first holding part retracted position and the second holding part retracted position. As described above, the vertical position of the support member 35 of the winding section 5A differs from the vertical position of the support member 35 of the winding section 5B. For this reason, the first catching position and the second catching position are different from each other in the vertical direction (the direction perpendicular to both the opposing direction and the arranging direction in the present invention). Therefore, as shown in FIG. 13, even if the holding portions 31A and 31B positioned at the catching position partially overlap each other when viewed from above and below, the holding portions 31A and 31B do not overlap each other. do not interfere.

After the plurality of yarns Y are captured by the holding portions 31A and 31B, the operator performs an input operation on the input portion of the control device 6 to continue the yarn hooking. The control device 6 continues threading according to the input signal. First, the control device 6 returns, for example, the second godet roller 4 to the rear position (see the solid line in FIG. 2).

Next, the controller 6 controls the operation of the linear slider 64A to move the slider 82 from the front end position to the rear end position (see FIG. 14(c)). As a result, the rear end portion of the support arm 61A moves rearward (one side in the arrangement direction of the present invention) along the cylinder body 81, and the front end portion of the support arm 61A moves diagonally rearward left along the guide rail 62A. Move (see FIG. 14(a)). As a result, the holding portion 31A moves obliquely to the rear left along the guide rail 62A while holding the yarn YA. Similarly, by controlling the operation of the linear slider 64B, the holding portion 31B moves obliquely to the rear right along the guide rail 62B (not shown).

Next, the control device 6 controls the operation of the air cylinder 65A to move the piston rod 84 from the retracted position to the extended position (see FIG. 15(b)). As a result, the pin 86 moves rearward, and the swing arm 63A swings (moves) leftward following it. Then, the tilt angle of the guide rail 62A with respect to the front-rear direction is changed, and the tilt angle of the holding portion 31A is also changed (see FIG. 15A). More specifically, the guide rail 62A extends obliquely forward left from the vicinity of the rearmost fulcrum guide 20A of the winding portion 5A toward the vicinity of the frontmost fulcrum guide 20A. At this time, the holding portion 31A is positioned at the yarn hooking start position of the present invention. The yarn hooking start position is a position on the rear side of the catching position. Similarly, by controlling the operation of the air cylinder 65B, the holding portion 31B moves to the yarn hooking start position (not shown).

Here, referring to FIG. 16A, the first godet roller 3 and the second godet roller 4 when the holding portion 31A (at least one of the pair of holding portions of the present invention) is positioned at the yarn hooking start position. and the positional relationship of the holding portion 31A. At this time, the first godet roller 3 is arranged on the upstream side of the holding portion 31A in the yarn running direction and on the front side of the holding portion 31A. The second godet roller 4 is arranged between the first godet roller 3 and the holding portion 31</b>A in the yarn running direction, and is arranged on the rear side of the first godet roller 3 . Furthermore, the second godet roller 4 is located in the rear position. At this time, the winding angle of the plurality of yarns Y on the second godet roller 4 is larger than the winding angle when the second godet roller 4 is positioned at the front side position (see FIG. 16(b)). Therefore, the force with which the second godet roller 4 holds the plurality of yarns Y is strong, and yarn swinging can be suppressed.

Further, the control device 6 controls the operation of the linear slider 64A to move the slider 82 from the rear end position to the front end position (see FIG. 17(c)). As a result, the front end portion of the support arm 61A moves forward along the cylinder body 81 (the other side in the arrangement direction of the present invention), and the front end portion of the support arm 61A moves obliquely forward and left along the guide rail 62A. (See FIGS. 17(a) and 18). As a result, the plurality of yarns YA respectively held in the plurality of holding grooves 45 of the holding portion 31A are hooked on the corresponding fulcrum guides 20A (see FIG. 18). The holding portion 31A moves to the thread hooking completion position, which is at least on the front side of the thread hooking start position (see the solid line in FIG. 17(a)). By moving the holding portion 31A from the yarn hooking start position to the yarn hooking completion position, all of the plurality of yarns YA are hooked on the corresponding fulcrum guides 20A. Similarly, by controlling the operation of the linear slider 64B, the holding portion 31B moves from the yarn hooking start position to the yarn hooking completion position (not shown). As a result, all of the plurality of yarns YB respectively held in the plurality of holding grooves 45 of the holding portion 31B are hung on the corresponding fulcrum guides 20B. In this way, threading to all of the fulcrum guides 20 is completed.

When the holding portions 31A and 31B reach the yarn hooking completion position, the states of the linear sliders 64A and 64B and the air cylinders 65A and 65B are substantially the same as before the yarn hooking starts (Fig. 10 ( a) to (c) and FIGS. 17(a) to (c)). In other words, the holding portion retracted position and the yarn hooking completion position described above are the same position. In other words, the holding portion 31A and the holding portion 31B return to the holding portion retracted position at the same time as the threading to the plurality of fulcrum guides 20 is completed.

After that, the control device 6 returns the plurality of fulcrum guides 20 to the winding position (separated position). The control device 6 further controls each part of the pair of winding parts 5 to perform threading on a plurality of bobbins B and the like (detailed description is omitted). As a result, it becomes possible to start winding the yarn Y onto each of the plurality of bobbins B. As shown in FIG.

As described above, in the present embodiment, after the yarn Y is caught by the pair of holding portions 31 at the catching position, the pair of holding portions 31 can be moved by the drive mechanism 32 without manual intervention. As a result, the accuracy of threading can be improved regardless of the skill level of the operator. Therefore, when threading the plurality of fulcrum guides 20 (fulcrum guides 20A, 20B) of the pair of winding sections 5 (winding sections 5A, 5B), the efficiency of threading can be improved.

Also, the plurality of fulcrum guides 20 are movable between the distant position and the close position. Accordingly, by positioning the plurality of fulcrum guides 20 at the close positions during threading, the moving distance of the pair of holding portions 31 can be shortened. Therefore, problems such as an increase in the size of the drive mechanism 32 can be suppressed as compared with the case where the pair of holding portions 31 move a long distance.

Moreover, in this embodiment, the holding portion 31A and the holding portion 31B can be independently moved. Therefore, it is possible to increase options for how to control the operations of the holding portions 31A and 31B.

Further, in the present embodiment, when the second godet roller 4 is positioned at the rear side position, the winding angle of the plurality of yarns Y on the second godet roller 4 is such that the second godet roller 4 is positioned at the front side position. It becomes larger than the winding angle at the time. As the winding angle increases, the holding force of the plurality of yarns Y by the second godet roller 4 increases. Therefore, when the pair of holding portions 31 holding a plurality of yarns Y is moved, yarn swinging can be suppressed as compared with the case where the second godet roller 4 is positioned at the front side position.

The drive mechanism 32 also has guide rails 62A and 62B and linear sliders 64A and 64B. Here, for example, in a configuration in which a pair of holding portions 31 are attached to the distal end portions of a pair of articulated arms (not shown) and the pair of holding portions 31 are moved by driving the pair of arms, precise control is required. As a result, there is a risk that the time and effort required for teaching, etc., will be enormous. In this regard, in the present embodiment, the pair of holding portions 31 can be moved with high accuracy with a simple configuration.

The drive mechanism 32 also includes air cylinders 65A, 65B configured to move the guide rails 62A, 62B, respectively. Thereby, the trajectory drawn by the pair of holding portions 31 can be appropriately changed while simplifying the shape of the guide rails 62A and 62B.

Air cylinders 65A and 65B are configured to swing guide rails 62A and 62B, respectively. As a result, compared to a configuration in which the entire guide rails 62A, 62B move in parallel, the movement area of the guide rails 62A, 62B can be kept narrow. Therefore, the guide rails 62A, 62B can be easily prevented from interfering with other members.

Further, since the cylinder main body 81 and the support member 35 are integrally provided, high rigidity can be ensured. Therefore, it is possible to suppress adverse effects on the linear sliders 64A and 64B due to vibration during the operation of the take-up machine 1, so that the durability of the linear sliders 64A and 64B can be enhanced.

Also, the pair of holding portions 31 is configured to be movable from the holding portion retracted position to the catching position. This embodiment is effective in the case where the pair of holding portions 31 become an obstacle when the pair of holding portions 31 are positioned at the catching position from the beginning when threading is performed.

Further, the holding portion retracted position is the same position as the yarn hooking completion position. Therefore, it is not necessary to return the pair of holding portions 31 to the holding portion retracted position after the pair of holding portions 31 have moved to the threading completion position (that is, after the completion of threading). Therefore, complication of the structure and operation of the thread hooking mechanism 30 can be suppressed.

Also, the first catching position and the second catching position are different from each other in the vertical direction. This prevents the holding portions 31A and 31B from interfering with each other when the holding portions 31A and 31B are moved to the capturing positions substantially simultaneously.

In addition, the thread hooking mechanism 30 has an adjusting section 33 . This allows the operator to finely adjust the positions of the pair of holding portions 31 when the plurality of yarns Y are respectively caught by the pair of holding portions 31 . Thereby, the yarn Y can be reliably captured by the pair of holding portions 31 . Therefore, the efficiency of threading can be further improved.

Further, the adjustment portion 33 has slide portions (support arms 61A and 61B) that support the pair of holding portions 31 so as to be slidable at least in the front-rear direction. Thereby, position adjustment in the front-back direction of a pair of holding|maintenance part 31 can be performed with a simple structure.

Further, the guide portion 55 (and the slide portion) can guide the pair of holding portions 31 moving from the holding portion retracted position to the front side. Therefore, it is possible to reliably avoid unintentional contact with a plurality of yarns Y when the pair of holding portions 31 move to the catching preparation position.

The yarn hooking mechanism 30 also has a regulating guide 8 and a separating roller 93 . As a result, the spacing between the plurality of yarns Y can be widened in the left-right direction by the separating roller 93 . Thereby, each of the pair of holding portions 31 can separate and easily catch a plurality of yarns Y. As shown in FIG. Therefore, the efficiency of threading can be further improved.

Further, the rotating shaft of the separating roller 93 extends in the left-right direction (that is, the direction substantially parallel to the direction in which the plurality of yarns Y are arranged by the regulating guide 8). Therefore, compared to a configuration in which the rotation axis direction is tilted with respect to the left-right direction (in other words, when the rotation axis direction and the direction in which the plurality of yarns Y are arranged do not match), the separating roller in the rotation axis direction 93 can be suppressed.

Also, in each of the pair of holding portions 31 , the interval between the entrances of the plurality of holding grooves 45 is substantially equal to the predetermined interval defined by the regulation guides 8 . That is, the interval between the entrances of the plurality of holding grooves 45 is as wide as the predetermined interval. Thus, the plurality of yarns Y can be easily separated and captured by the pair of holding portions 31 . Therefore, the efficiency of threading can be further improved.

Further, the separating roller 93 is configured to be movable between a roller retracted position and a roller contact position. The present invention is effective in the case where the separating roller 93 is in the way when the separating roller 93 is positioned at the roller contact position except when the intervals between the plurality of yarns Y are widened.

Further, by rotating the rotating arm 91 about the rotating shaft 94, the separating roller 93 can be moved between the roller retracted position and the roller contact position. For this reason, positional fluctuations of the roller support portion and the separating roller 93 can be suppressed, for example, compared to a configuration in which a member (roller support portion) that supports the separating roller 93 is moved linearly. Therefore, the positional accuracy of the separating roller 93 can be improved.

Further, the rotating shaft 94 extends along the direction in which the rotating shaft of the separating roller 93 extends. As a result, when viewed from the direction in which the rotating shaft 94 extends, the separating roller 93 looks like a circle (that is, the separating roller 93 looks compact). Therefore, compared to the case where the direction in which the rotating shaft 94 extends and the direction in which the rotating shaft of the separating roller 93 extends are not aligned, the movement area of the separating roller 93 can be made compact. Therefore, it is possible to effectively prevent the separating roller 93 from interfering with other members.

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

(1) In the above embodiment, the adjustment portion 33 is provided at least on the swing arms 63A and 63B (that is, the play portion 77 formed at the front end portion of the guide hole 76 is positioned between the pair of holding portions 31). ). However, it is not limited to this. For example, the comb guide 41 may be configured to be swingable with respect to the above-described intervening member 42 . Thereby, the intervening member 42 may function as the adjusting portion of the present invention. Alternatively, there may be a separate adjustment that can be operated by the operator. For example, the comb guide 41 may be connected to the support arms 61A, 61B via springs (compression coil spring, tension coil spring, and/or torsion coil spring, etc.), not shown, instead of the intervening member 42 .

(2) In the above-described embodiment, the vertical position of the support member 35 of the winding section 5A is lower than the vertical position of the support member 35 of the winding section 5B by about 5 mm, for example. As a result, the first catching position and the second catching position are different from each other in the vertical direction. However, it is not limited to this. For example, the vertical position of the support member 35 of the winding section 5A and the vertical position of the support member 35 of the winding section 5B may be substantially the same. In this case, the drive mechanism 32 is configured such that the vertical movement distance of the holding portion 31A from the first holding portion retracted position and the vertical movement distance of the holding portion 31B from the second holding portion retracted position are different from each other. may be configured. Alternatively, as long as the holding portion 31A and the holding portion 31B are configured so as not to overlap when viewed in the vertical direction, the first catching position and the second catching position may be substantially the same position in the vertical direction. .

(3) In the above-described embodiments, after the pair of holding portions 31 has moved from the holding portion retracted position to the catching preparation position, the operator operates the adjusting portion 33 to move each of the pair of holding portions 31 to the catching position. A plurality of yarns Y are captured by each of the pair of holding portions 31. As shown in FIG. However, it is not limited to this. For example, as shown in FIGS. 19(a) to 19(d), a yarn hooking mechanism 101 is provided that is configured to allow a pair of holding portions 131 (described later) to catch a plurality of yarns Y without manual intervention. It's okay to be. Specifically, the thread hooking mechanism 101 has a positioning portion 110 . The positioning part 110 is for positioning the pair of holding parts 31 at the capture preparation position by restricting the movement of the pair of holding parts 131 in the left-right direction.

The positioning portion 110 may be fixed to the rotating arm 91 of the thread interval increasing portion 34, for example, as shown in FIGS. 19(a) and 19(b). That is, the positioning portion 110 may be configured to be rotatable integrally with the rotating arm 91 . The positioning portion 110, together with the rotating arm 91, has a predetermined first position (see the two-dot chain line in FIG. 19A) and a second position for positioning the pair of holding portions 31 (FIG. 19A). (see solid line in ). The configuration of the positioning portion 110 when positioned at the second position will be described below. For example, as shown in FIGS. 19A to 19C, the positioning section 110 has an extension member 111, a position adjusting member 112, and a stopper member 113 (stopper section of the present invention). The extension member 111 is, for example, a member fixed to the rotating arm 91 and extending in the left-right direction (see FIG. 19B). A portion of the extension member 111 extending in the left-right direction is, for example, a flat plate shape. A right end portion of the extension member 111 is formed with a through hole 114 that penetrates in the thickness direction and extends, for example, in the left-right direction. The position adjusting member 112 is, for example, a flat member. The position adjusting member 112 has a through hole 115 (see FIG. 19(d)) penetrating in the thickness direction, and the male screw portion of the bolt 116 can be inserted through the through hole. The front portion of position adjusting member 112 is attached to the right end of extension member 111 by bolts 116 and nuts 117, for example. A male threaded portion of the bolt 116 is inserted through the through holes 114 and 115 . When bolt 116 and nut 117 are loosened, position adjustment member 112 can be moved laterally relative to extension member 111 by an operator. The stopper member 113 is fixed to the rear portion of the position adjusting member 112 . The stopper member 113 is, for example, a block-shaped member arranged to extend vertically when positioned at the second position. The stopper member 113 is arranged at a position between the pair of holding portions 131 (see FIGS. 20A and 20B) in the left-right direction when positioned at the second position. The stopper member 113 has, for example, a shape that does not hinder the movement of the pair of holding portions 131 that have moved to the capture preparation position and engages with the stopper member 113 when the pair of holding portions 131 retreat from the capture position. are doing. For example, when the stopper member 113 is positioned at the second position, the rear portion of the stopper member 113 is curved (curved surface 118) when viewed from above, and the front portion of the stopper member 113 extends in the front-rear direction. (plane 119). The length (in other words, width) of the curved surface 118 in the left-right direction is narrower toward the front. By adjusting the lateral position of the stopper member 113, the capture preparation positions of the pair of holding portions 131 are adjusted. After that, the pair of holding portions 131 can catch a plurality of yarns Y when moved to the catching position on the rear side of the catching preparation position. Note that the shape of the stopper member 113 is not limited to this. The shape of the stopper member 113 may have another shape according to the shape of the pair of holding portions 131 . Further, in this modified example, the adjusting section 33 described above may not be provided.

A pair of holding portions 131 (see FIGS. 20A and 20B) has the following configuration. As shown in FIG. 20(a), the comb guide 141A of the holding portion 131A has a body portion 143. As shown in FIG. As a difference between the body portion 143 and the body portion 43 described above (see FIG. 5A), the body portion 143 has a contact surface 144 (a curved surface 145 and a flat surface 146) that can come into contact with the stopper member 113. As shown in FIG. Curved surface 145 has a shape along curved surface 118 and plane 146 has a shape along plane 119 . The comb guide 141B of the holding portion 131B has a shape symmetrical to the comb guide 141A (see FIG. 20(b)). Note that the shape of the contact surface 144 is not limited to the shape described above.

In the above configuration, when the pair of holding portions 131 are moved from the holding portion retracted position to the captured position by the driving mechanism 32 (see FIG. 4A, etc.), the pair of holding portions 131 face each other in the left-right direction. placed in At this time, the pair of holding portions 131 come into contact with the stopper member 113 so as to sandwich the stopper member 113 in the left-right direction (see FIG. 20(c)). Thereby, the positions of the pair of holding portions 131 are determined. By appropriately adjusting the position of the stopper member 113 in advance, the pair of holding portions 131 can be positioned at the optimized capturing position. After that, the pair of holding portions 131 retreat, whereby the plurality of yarns Y are captured by the pair of holding portions 131 and held separately. Therefore, the plurality of yarns Y can be captured by the pair of holding portions 131 without the operator manually moving the pair of holding portions 131 . In such a configuration, the comb guides 141A and 141B may not have the through holes 46 and the handle portions 47 described above.

In the configuration provided with the positioning portion 110, the device (the first rail driving portion and the second rail driving portion of the present invention) for moving the pair of holding portions 131 from the holding portion retracted position to the captured position may be, for example, It is preferable that the air cylinders 65A and 65B are configured to be driven by fluid pressure. By doing so, when the pair of holding portions 131 are pushed back from the stopper member 113 by the law of action and reaction, the load applied to the first rail driving portion and the second rail driving portion can be reduced.

(4) In the modified example of (3) described above, the positioning portion 110 is attached to the thread interval increasing portion 34, but the present invention is not limited to this. The positioning part 110 may be configured to be movable by another mechanism. Alternatively, the positioning section 110 may not necessarily be configured to be movable.

(5) In the above-described embodiments, the drive mechanism 32 is configured such that the holding portion retracted position is the same position as the yarn hooking completion position. However, it is not limited to this. The drive mechanism 32 may be configured to move the pair of holding portions 31 to a position different from the yarn hooking completion position after the yarn hooking to the plurality of fulcrum guides 20 is completed. Such a configuration is effective, for example, when the pair of holding portions 31 become an obstacle if the pair of holding portions 31 remain positioned at the threading completion position after the completion of threading.

(6) In the above embodiments, the air cylinders 65A, 65B are configured to swing the guide rails 62A, 62B. However, it is not limited to this. For example, a mechanism for translating the guide rails 62A and 62B may be provided.

(7) In the above embodiments, the guide rails 62A and 62B are linear, and the positions of the guide rails 62A and 62B are changed according to the purpose. However, it is not limited to this. For example, a pair of guide rails (not shown) that do not need to be moved may be provided along a track for moving the pair of holding parts 31 .

(8) In the above embodiments, the pair of holding portions 31 are moved by the linear sliders 64A and 64B. However, it is not limited to this. For example, a pair of holding parts 31 may be attached to the distal ends of a pair of articulated arms (not shown), and the pair of holding parts 31 may be moved by driving the pair of arms. However, in this case, teaching is required to properly operate the pair of arms.

(9) In the above-described embodiments, the plurality of fulcrum guides 20 are movable between the distant position and the close position. However, it is not limited to this. The plurality of fulcrum guides 20 may be immovable. However, in this case, the drive mechanism 32 may be enlarged in the front-rear direction.

(10) In the above-described embodiments, the control device 6 returns the second godet roller 4 to the rear position before starting to move the pair of holding portions 31 from the threading start position to the threading completion position. However, it is not limited to this. In principle, the second godet roller 4 can be returned to the rear position after the plurality of yarns Y are captured by the pair of holding portions 31 and before the yarns are completely hooked onto the plurality of bobbins B.

(11) In the above-described embodiments, the pair of holding portions 31 is moved from the holding portion retracted position to the capturing position. However, it is not limited to this. The pair of holding parts 31 may be positioned at the catching position (or the catching preparation position) from the beginning as long as the pair of holding parts 31 does not become an obstacle.

(12) In the above-described embodiments, the spacing between the entrances of the plurality of holding grooves 45 in the direction in which the plurality of holding grooves 45 are arranged is substantially the same as the predetermined spacing defined by the regulation guide 8 in the left-right direction. bottom. However, it is not limited to this. The interval between the entrances of the plurality of holding grooves 45 may be different from the predetermined interval.

(13) In the above-described embodiments, the rotation shaft 94 of the yarn spacing increasing portion 34 extends along the direction in which the rotation shaft of the separating roller 93 extends. However, it is not limited to this. The direction in which the rotating shaft 94 extends may be offset from the direction in which the rotating shaft of the separating roller 93 extends.

(14) In the above-described embodiments, the yarn interval increasing section 34 is configured so that the separating roller 93 can rotate around the rotation shaft 94 . However, it is not limited to this. For example, the yarn interval increasing section 34 may be configured so that the separating roller 93 can move linearly. Thereby, the separating roller 93 may be moved between the roller retracted position and the roller contact position.

(15) In the above embodiments, the separating roller 93 is moved by the operator. However, it is not limited to this. A driving device (not shown) may be provided to move the separating roller 93 between the roller retracted position and the roller contact position.

Further, in this modified example, the yarn hooking mechanism 101 having the positioning portion 110 described above may be provided. In this case, the operator only needs to thread the first godet roller 3, the second godet roller 4, and the separating roller 93 and perform an input operation to the input section of the control device 6, and the thread hooking mechanism 101 guides a plurality of fulcrums. You can complete the threading to 20. In this case, an automatic threading device (not shown) having a robot arm (not shown), for example, disclosed in JP-A-2017-82379, may be provided. Instead of the operator, the automatic threading device may thread the first godet roller 3 , the second godet roller 4 and the separating roller 93 and communicate with the control device 6 . By doing so, it is possible to perform threading without any manual intervention.

(16) In the above embodiments, the separating roller 93 is movable between the roller retracted position and the roller contact position. However, it is not limited to this. If the separating roller 93 does not become an obstacle, the separating roller 93 may be immovable.

(17) In the above-described embodiments, the rotating shaft of the separating roller 93 extends in the left-right direction. However, it is not limited to this. The rotating shaft of the separating roller 93 may be slightly inclined from the horizontal direction.

(18) For example, the linear sliders 64A and 64B may function as the adjustment section and slide section of the present invention as follows. After moving the holding portions 31A and 31B from the holding portion retracted positions to the capture preparation positions, the control device 6 controls the solenoid valve EV1 (see FIG. 6A), which is a five-way solenoid valve, to move the piston chamber 81F. , 81R. This allows the operator to manually move the slider 82 back and forth. In this case, the through holes 72 of the support arms 61A and 61B do not necessarily have to extend in the front-rear direction. Further, in this case, the guide portion 55 may not be provided.

The configuration for discharging compressed air from both the piston chambers 81F and 81R is not limited to that shown in FIG. 6(a). For example, by providing two three-way solenoid valves (not shown) instead of the solenoid valve EV1 and appropriately providing paths for supplying and discharging compressed air, compressed air is discharged from both the piston chambers 81F and 81R. You can let me. Further, when the linear sliders 64A and 64B do not function as the adjusting portion and the sliding portion of the present invention, another type of solenoid valve such as a known four-way solenoid valve may be provided.

(19) A component corresponding to the slide portion of the present invention may not necessarily be provided.

(20) In the above-described embodiments, the control device 6 controls the driving section 32A and the driving section 32B substantially simultaneously. However, it is not limited to this. The control device 6 may vary the timing of controlling the driving section 32A and the timing of controlling the driving section 32B. Thereby, for example, one of the pair of holding portions 31 can start moving before the other. Therefore, this modified example is effective in the case where attempts to start moving the pair of holding portions 31 at the same time cause some kind of adverse effect. For example, the timing of moving the holding portions 31A and 31B from the holding portion retracted position to the capture preparation position can be made different. As a result, for example, when an inexperienced operator causes the pair of holding portions 31 to catch a plurality of yarns Y, the holding portions 31A and 31B are both positioned at the catching preparation positions and are close to each other. It is possible to suppress erroneous operations caused by touching a member that does not operate.

(21) The paths connecting the linear slider 64A with the supply port Ps and the discharge ports Pe1 and Pe2 are not limited to those shown in FIG. 6(a). The same applies to the linear slider 64B. Further, the paths connecting the air cylinder 65A, the supply port Ps and the discharge ports Pe1 and Pe2 are not limited to those shown in FIG. 6(b). The same applies to the air cylinder 65B.

(22) In the above-described embodiments, the driving section 32A and the driving section 32B are operable independently of each other, but the present invention is not limited to this. For example, the path of the compressed air may be configured so that the driving section 32A and the driving section 32B operate integrally.

(23) In the above embodiments, the cylinder body 81 of the linear slider 64A is fixed to the support member 35 (the same applies to the linear slider 64B). However, it is not limited to this. For example, even if a rocking shaft (not shown) extending along the vertical direction is provided at the rear end of the cylinder body 81 and the cylinder body 81 is configured to be rockable around the rocking shaft. good. In this case, the guide rail 62A and the cylinder main body 81 are integrally swung (the same applies to the guide rail 62B). Also, the support arm 61A may be fixed to the slider 82 (the same applies to the support arm 61B).

(24) In the above-described embodiments, the yarn hooking mechanism 30 has both the driving mechanism 32 that drives and moves the pair of holding parts 31 and the yarn interval increasing part 34 (the separating roller 93). However, it is not limited to this. The yarn hooking mechanism 30 may have only one of the drive mechanism 32 and the yarn interval increasing portion 34 . Even with a configuration in which only one of them is provided, the efficiency of threading can be improved when threading onto the plurality of fulcrum guides 20 of the pair of winding sections 5 respectively. If the yarn hooking mechanism 30 does not have the drive mechanism 32, for example, a yarn hooking member that can be operated by the operator (see, for example, Japanese Patent Application Laid-Open No. 2017-114573) is used for threading. Further, when the yarn hooking mechanism 30 does not have the yarn interval increasing portion 34, the intervals between the plurality of holding grooves (not shown) provided in the pair of holding portions (not shown) are equal to the above-described plurality of holding grooves. It becomes narrower than the interval of the grooves 45 . Also, when the yarn hooking mechanism 30 does not have the yarn interval increasing portion 34, the catching positions of the holding portions 31A and 31B are positions between the second godet roller 4 and the suction gun SG in the yarn running direction.

(25) In the above embodiments, the yarn hooking mechanism 30 is configured to hook a plurality of yarns Y to the plurality of fulcrum guides 20 of the pair of winding units 5 . However, it is not limited to this. For example, when a plurality of other yarn guides (not shown) arranged side by side in the front-rear direction are provided in the take-up machine 1, a plurality of yarns Y are respectively hung on these plurality of yarn guides. A thread hooking mechanism (not shown) may be provided.

(26) Although the take-up machine 1 has a pair of winding units 5 (winding units 5A and 5B), it is not limited to this. The take-up machine 1 may include, for example, only the winding section 5A out of the winding sections 5A and 5B. In this case, the yarn hooking mechanism 30 may have the holding portion 31A and the driving portion 32A and may not have the holding portion 31B and the driving portion 32B. Additionally/or alternatively, the thread hooking mechanism 30 may have a thread spacing increasing portion 34 .

(27) The present invention is not limited to the take-up machine 1, but can be applied to various yarn winders configured to wind a plurality of yarns Y.

Each of the pair of winding units 5 (winding unit 5A and winding unit 5B) is configured to wind a plurality of yarns Y onto a plurality of bobbins B to simultaneously form a plurality of packages P. . The winding section 5A and the winding section 5B are arranged below the first godet roller 3 and the second godet roller 4, respectively. The winding portion 5A and the winding portion 5B are arranged symmetrically (plane symmetrically) (see FIG. 1). More specifically, the winding unit 5A arranged on the left side and the winding unit 5B arranged on the right side are arranged on both sides of the second godet roller 4 in the left-right direction, and are arranged to accommodate the plurality of yarns Y fed from the second godet roller 4. They are arranged so as to face each other across a thread path. Each of the pair of winding units 5 is configured to wind half of the plurality of yarns Y sent from the second godet roller 4 (for example, 16 yarns each in this embodiment). More specifically, the winding section 5A winds the left 16 yarns YA, and the winding section 5B winds the right 16 yarns YB.

The linear slider 64A is a device for moving the support arm 61A in the front-rear direction. The linear slider 64A is, for example, a known rodless cylinder operated by compressed air. The linear slider 64A has a cylinder body 81 (cylinder body 81A) and a slider 82 . The cylinder main body 81A (first main body of the present invention) extends in the front-rear direction. The cylinder main body 81A is fixed to the rear portion of the support member 35A by, for example, a fixture (not shown). That is, the cylinder main body 81A is provided integrally with the support member 35A. Alternatively, the cylinder body 81A may be welded to the support member 35A, for example. The slider 82 is configured to be slidable in the front-rear direction along the cylinder body 81 . A support arm 61A is attached to the slider 82 so as to be able to swing. The slider 82 can move between the vicinity of the front end portion and the vicinity of the rear end portion of the cylinder body 81 by supplying compressed air to the cylinder body 81 and discharging compressed air from the cylinder body 81 . As a more specific example, as shown in FIG. 6A, the cylinder body 81 has a piston chamber 81F arranged on the front side of the slider 82 and a piston chamber 81R arranged on the rear side of the slider 82. formed. The piston chamber 81F is connected to a compressed air supply port Ps and an exhaust port Pe2 via an electromagnetic valve EV1, which is, for example, a known five-way electromagnetic valve. The piston chamber 81R is connected to the supply port Ps and the discharge port Pe1 via the solenoid valve EV1. Electromagnetic valve EV1 is electrically connected to control device 6 . The control device 6 controls the solenoid valve EV1 to control the supply and discharge of compressed air. Compressed air is supplied from the supply port Ps to the piston chamber 81F and discharged from the piston chamber 81R to the discharge port Pe1, whereby the slider 82 moves rearward. Compressed air is supplied from the supply port Ps to the piston chamber 81R and discharged from the piston chamber 81F to the discharge port Pe2, thereby moving the slider 82 forward. Instead of the linear slider 64A, another cylinder mechanism driven by fluid such as compressed air, or an electric drive mechanism (for example, a ball screw mechanism or a rack and pinion mechanism) may be provided.

The air cylinder 65A is a device for swinging the swing arm 63A and the guide rail 62A. The air cylinder 65A has a cylinder body 83 and a piston rod 84. As shown in FIG. The cylinder body 83 extends in the front-rear direction. The cylinder body 83 is attached to the front portion of the support member 35A. The piston rod 84 extends rearward from the rear end of the cylinder body 83, for example. The piston rod 84 can be expanded and contracted by supplying compressed air to the cylinder body 83 and discharging compressed air from the cylinder body 83 . As a more specific example, as shown in FIG. 6B, the cylinder body 83 has a piston chamber 83F formed on the front side and a piston chamber 83R formed on the rear side. The piston chamber 83F is connected to a compressed air supply port Ps and a compressed air discharge port Pe2 via an electromagnetic valve EV2 having the same configuration as the five-way electromagnetic valve described above. The piston chamber 83R is connected to the supply port Ps and the discharge port Pe1 via the electromagnetic valve EV2. Compressed air is supplied from the supply port Ps to the piston chamber 83F and discharged from the piston chamber 83R to the discharge port Pe1, whereby the piston rod 84 moves rearward. Compressed air is supplied from the supply port Ps to the piston chamber 83R and discharged from the piston chamber 83F to the discharge port Pe2, thereby moving the piston rod 84 forward . A pin 86 extending upward is provided at the upper end of a rod end 85 attached to the tip of the piston rod 84 (see FIGS. 4(a), 10(b), etc.). The pin 86 is inserted through the guide hole 76 of the swing arm 63A. A disk member 87 having a diameter larger than that of the pin 86 is attached to the upper end of the pin 86 to prevent the pin 86 from coming off the guide hole 76 . Instead of the air cylinder 65A, another cylinder mechanism driven by fluid or an electric drive mechanism (for example, a ball screw mechanism or a rack and pinion mechanism) may be provided.

First, the control device 6 controls the operation of the air cylinder 65A to move the piston rod 84 from the extended position (see FIG. 10(b)) to the retracted position (see FIG. 11(b)). As a result, when the pin 86 moves forward, the swing arm 63A and the guide rail 62A swing counterclockwise so that the guide hole 76 of the swing arm 63A follows the pin 86 (FIG. 11). (a)). Then, the front end portion of the support arm 61A and the holding portion 31A swing rightward following the guide rail 62A (see FIG. 11(a)). As a result, the holding portion 31A begins to move from the holding portion retracted position to the vicinity of a catching position (described later) where a plurality of yarns YA can be caught (see the rightward arrow in FIG. 11(a)). Here, as described above, the guide 53 is attached to the support member 35 (see region R1 in FIG. 11A and its enlarged view). A guide portion 55 (more specifically, a guide surface 56 ) of the guide 53 is arranged on a movement track of a pin 57 provided on the comb guide 41 . Therefore, since the pin 57 moves while contacting the guide surface 56, the comb guide 41 moving from the holding portion retracted position is guided at least forward along the guide surface 56 (see FIG. 11A). , see arrows in the enlarged view of region R1). Further, as the comb guide 41 is guided forward, the support arm 61A to which the holding portion 31A is attached moves to the arm front side position (see the right obliquely forward arrow in FIG. 11(a)). As a result, the holding portion 31A moves from the holding portion retracted position to the catching preparation position for the operator to make the holding portion 31A catch the plurality of yarns YA. The capture preparation position is a position at least forward of the capture position. Although illustration is omitted, the capture preparation position of the holding part 31A is a position immediately above the left portion of the separating roller 93 and immediately in front of the plurality of yarns YA. Further, when the holding portion 31A is moved from the holding portion retracted position to the catching preparation position, the holding portion 31B is moved from the holding portion retracted position to the catching preparation position for the operator to perform the work of catching the yarn YB. . Although not shown, the capture preparation position of the holding part 31B is a position immediately above the right side portion of the separating roller 93 and immediately in front of the plurality of yarns YB. The capture preparation position of the pair of holding parts 31 is a position between the second godet roller 4 and the separating roller 93 in the vertical direction. In other words, the capture preparation positions of the pair of holding portions 31 are positions downstream of the second godet roller 4 and upstream of the separating roller 93 in the yarn traveling direction. The control device 6 temporarily stops the operation of the yarn hooking mechanism 30 in this state.

(3) In the above-described embodiments, after the pair of holding portions 31 has moved from the holding portion retracted position to the catching preparation position, the operator operates the adjusting portion 33 to move each of the pair of holding portions 31 to the catching position. A plurality of yarns Y are captured by each of the pair of holding portions 31. As shown in FIG. However, it is not limited to this. For example, as shown in FIGS. 19(a) to 19(d), a yarn hooking mechanism 101 is provided that is configured to allow a pair of holding portions 131 (described later) to catch a plurality of yarns Y without manual intervention. It's okay to be. Specifically, the thread hooking mechanism 101 has a positioning portion 110 . The positioning portion 110 is for positioning the pair of holding portions 131 at the capturing preparation positions by restricting the movement of the pair of holding portions 131 in the left-right direction.
