The present invention relates to a wire winder.

Patent Document 1 discloses a yarn winding machine that unwinds yarn from a yarn feeding package, and then winds the yarn on a winding bobbin to form a winding package. Specifically, the yarn winding machine is provided with a motor for rotationally driving the yarn feeding package, and a guide roller (direction changing portion) arranged on the outer side of the yarn feeding package in the radial direction of the yarn feeding package. The rotation axis of the wire feeding package faces the vertical direction, and the winding bobbin is arranged above the wire feeding package (the outer side of the wire feeding package in the axial direction). In such a yarn winding machine, when the yarn feeding package is driven to rotate, the yarn is unwound from the yarn feeding package, and then guided upward (winding package side) by the direction changing portion.

Here, from the viewpoint of preventing yarn breakage, etc., the tension of the yarn is required to be kept constant due to the variation in the length of the yarn path from the feeding package to the winding package due to the traverse movement of the unwound yarn, etc. etc., the tension may fluctuate frequently. Then, the said direction changing part is comprised so that it can follow and move in the radial direction (horizontal direction) of a wire feed package, and is urged|biased by a spring. In this way, the direction changing portion is driven to move in accordance with the change in the length of the yarn passage, whereby the tension or slack of the yarn is relieved, and the tension fluctuation is suppressed.

[Problems to be Solved by Invention]

In the yarn winding machine described in Patent Document 1, since the direction changing portion is driven to move in the direction perpendicular to the direction in which the wire is guided by the direction changing portion, for example, the following problems may occur. That is, due to the driven movement of the direction changing portion, the yarn traveling on the downstream side of the yarn traveling direction of the direction changing portion is likely to move greatly in the horizontal direction (in other words, roll is likely to occur), and the thread path is easily fluctuated. Therefore, if the member is arranged in the vicinity of the wire passage, there is a possibility that the wire will interfere with the member. In order to avoid such interference, it is necessary to secure a wide space around the wire passage, and there is a problem that the apparatus may become large.

An object of the present invention is to suppress the variation of the thread path caused by the driven movement of the direction changing portion. [Technical means to solve problems]

The yarn winding machine of the first invention is a winding bobbin arranged at least on one side of the yarn feeding package in the axial direction of the yarn feeding package after unwinding the yarn from the rotating yarn feeding package. The yarn is wound to form a winding package, which is characterized in that a direction changing portion is provided, and the direction changing portion is arranged on the outer side of the yarn feeding package in the radial direction of the yarn feeding package, and is directed toward the axis having the axis. The wire is guided to one side in the guiding direction of the component to be directed; the direction changing portion is configured so as to be movable in the moving direction at an angle of 45 degrees or less with the guiding direction, and directed toward at least the above The other side in the guiding direction applies a given force.

In the present invention, first, the yarn unwound from the yarn feeding package is guided toward one side in the guide direction by the direction changing portion. The direction changing portion is biased toward at least the other side in the guide direction, and the yarn is always stretched by the direction changing portion. In this way, a predetermined tension is imparted to the yarn. Moreover, by making the direction change part movable, the tension|tensile_strength fluctuation|variation of a thread can be suppressed as follows. That is, for example, when the winding speed of the yarn becomes faster than the unwinding speed, the direction changing portion is driven to move by pulling the yarn to one side of the guide direction. In this way, the thread path is shortened and the tension of the thread caused by the relative speed difference is suppressed. On the contrary, when the winding speed of the wire is relatively slow, the wire is about to become loose, because the direction changing part is forced as described above, and the direction changing part can be driven to move to the other side of the guiding direction while the direction changing part is driven. Silk stretch. In this way, the yarn passage is lengthened and the slack of the yarn due to the relative speed difference is suppressed.

Furthermore, in the present invention, the angle formed by the moving direction of the direction changing portion and the guide direction is reduced to 45 degrees or less. Therefore, compared with the structure in which the moving direction and the guiding direction are perpendicular to each other or nearly perpendicular to each other, the thread on the downstream side of the thread advancing direction of the direction changing portion can be suppressed from being greatly swayed by the driven movement of the direction changing portion (variation of the thread path). . Therefore, the variation of the thread path caused by the driven movement of the direction changing portion can be suppressed.

In the yarn winding machine of the second invention, in the first invention, the moving direction has a component in the vertical direction, and the force is gravity.

In the present invention, the direction changing portion can be moved by the action of gravity. Therefore, compared with the structure which biases a direction change part by a spring etc., the simplification of a structure and cost reduction can be aimed at. Furthermore, a stable force due to gravity can be applied to the direction changing portion, and the running yarn can be stably drawn. In this way, tension can be stably imparted to the running yarn.

A yarn winding machine according to a third invention, in the first or second invention, is provided with a rail member extending in the moving direction and movably guiding the direction changing portion.

For example, in a structure using a dancer roller connected to a general swing type dancer arm as the direction changing portion, the structure of the member to be driven is complicated, and the mass (inertial mass) of the member to be driven is increased. On the other hand, there is a problem that the followability of the direction changing section is not good. In the present invention, since only the direction changing portion is driven to move along the rail member, the structure of the member that is driven to move can be simplified, and the inertial mass of the member can be reduced. Therefore, the followability of the direction changing portion can be improved.

In the yarn winding machine of a fourth invention, in any one of the first to third inventions, the moving direction is parallel to the axial direction.

If the moving direction is inclined with respect to the axial direction of the yarn feeding package, when the direction changing part moves, the distance between the direction changing part and the surface of the yarn feeding package will change, and the length of the yarn passage will change. In the present invention, since the moving direction is parallel to the axial direction, such variation in the length of the wire passage can be suppressed.

In the yarn winding machine according to a fifth invention, in any one of the first to fourth inventions, the axial direction is parallel to the vertical direction.

For example, if the yarn feeding package is arranged horizontally so that its axial direction is parallel to the horizontal direction, the rotation axis of the yarn feeding package will be deflected downward due to the influence of gravity and the yarn feeding package will rotate. Doubt of becoming unstable. In the present invention, since the axial direction of the wire feeding package is parallel to the vertical direction, deflection of the rotating shaft due to gravity can be prevented. Therefore, the instability of the rotation of the yarn feed package can be suppressed.

A yarn winding machine according to a sixth invention, in any one of the first to fifth inventions described above, is provided with: a yarn feeding package disposed between the yarn feeding package and the direction changing portion in the yarn advancing direction and between the feeding yarn The spacer portion on the outer side in the radial direction of the package, the spacer portion is configured to be movable in the axial direction, and/or the contact portion with the wire extends toward the axial direction.

The yarn unwound from the rotating yarn feeding package travels toward the direction changing portion while traversing in the axial direction of the yarn feeding package with the direction changing portion as a fulcrum. Here, if the angle of traversing with the direction changing portion as the traverse fulcrum is large, the length of the yarn path from the surface of the yarn feeding package to the direction changing portion during traverse will vary greatly. However, in order to reduce the traverse angle, if the direction changing portion is disposed away from the yarn feeding package, there arises a problem that the size of the apparatus is increased. In the present invention, the yarn unwound from the yarn feeding package travels toward the direction changing portion via the partition portion. In this way, even if the direction changing portion is not arranged away from the yarn feeding package, the yarn path from the surface of the yarn feeding package to the direction changing portion can be lengthened. In addition, since the spacer can be driven to move and/or its contact portion with the wire extends in the axial direction, the wire can be smoothly slid in the axial direction. Therefore, the size of the apparatus can be suppressed and the traverse angle of the yarn after unwinding can be reduced.

A yarn winding machine according to a seventh invention, in any one of the first to sixth inventions, is provided with a yarn feeding roller disposed on the downstream side in the yarn advancing direction of the direction changing portion.

In the structure in which the yarn is further fed to the downstream side in the yarn advancing direction by the yarn feeding roller, if the yarn is loosened on the immediately upstream side of the yarn feeding roller with respect to the yarn advancing direction, the yarn is The peripheral surface slips, and there is a concern that the wire cannot travel normally. In the present invention, since the yarn is always drawn toward the other side (that is, the upstream side) of the guide direction by the direction changing portion, it is possible to suppress the yarn from becoming slack on the upstream side in the yarn traveling direction rather than the yarn feed roller. .

A yarn winding machine according to an eighth invention, in any one of the first to seventh inventions described above, is provided with a package support portion that rotatably supports the yarn feeding package, and a package support portion which is vertically arranged to intersect with the vertical direction. The machine on one side of the package support portion in the cross direction, the package support portion can be used for unwinding the yarn from the feeding package. It moves between the replacement positions at least on the other side of the aforementioned intersecting direction.

Generally, as for the above-mentioned yarn winding machines, a plurality of them are installed in parallel in the horizontal direction. In addition, the other side in the intersecting direction of the machine table is generally a work space when changing the feed package. In such a structure, if the package support portion cannot be moved, when a plurality of yarn winding machines are installed in parallel, there is a concern that it is difficult to secure a space for the replacement work of the yarn feed package. In the present invention, the package support portion can be moved to the replacement position farther from the table than the unwinding position (that is, on the work space side) in at least the intersecting direction, so that a wide space for the replacement work can be secured. . Therefore, the replacement work of the wire feed package can be facilitated.

A yarn winding machine of a ninth invention, in any one of the first to eighth inventions, further comprises: an unwinding drive unit for rotationally driving the yarn feeder package, and an unwinding drive unit for rotationally driving the winding package. A winding drive unit, a position detection unit that detects a position in the moving direction of the direction changing unit, and at least one of the unwinding drive unit and the winding drive unit is controlled based on a detection result by the position detection unit control department.

For example, in a state where the rotation speed of the yarn feed package is constant, if the unwinding of the yarn progresses and the yarn feed package becomes thinner, the unwinding speed of the yarn decreases and the winding speed becomes relatively fast. May be pulled to one side of the guide direction and moved substantially. At this time, if the direction changing portion moves to the outside of the end face of the yarn feed package in the axial direction, the yarn may fall off the end face of the yarn feed package and the yarn may not travel normally. In the present invention, the control unit controls at least one of the unwinding drive unit and the winding drive unit based on the detection result by the position detection unit. In this way, by actively changing the speed difference between the winding speed and the unwinding speed of the yarn, the direction changing portion can be actively moved. Therefore, for example, the position of the direction changing portion can be controlled by performing feedback control such that the position of the direction changing portion is brought close to the target position. Therefore, the large movement of the direction changing portion can be suppressed.

A tenth invention of the yarn winding machine according to any one of the first to ninth inventions, wherein the position detection unit is an optical sensor that optically detects the position of the direction changing unit in the moving direction. device.

For example, in a structure employing a magnetic sensor that magnetically detects the position of the direction changing portion, the direction changing portion must be formed of a conductor such as metal, or the direction changing portion must be mounted with a conductor. Therefore, the mass of the direction changing part increases, and there is a possibility that the direction changing part becomes difficult to follow and move. In addition, in a structure employing, for example, a contact-type position sensor, the sensor is likely to be worn out due to frequent movement of the direction changing portion, and there is a concern that the sensor deteriorates prematurely. In the present invention, since the position of the direction changing portion can be detected optically, it is possible to suppress an increase in the mass of the direction changing portion, premature deterioration of the position detecting portion, and the like.

Next, an embodiment of the present invention will be described with reference to FIGS. 1 to 4 . The up-down direction and the left-right direction shown in FIG. 1 are set as the up-down direction (vertical direction to which gravity acts) and the left-right direction of the rewinder 1, respectively. The front-rear direction shown in FIG. 2 is set as the front-rear direction of the rewinder 1 . The direction in which the wire Y travels is set as the wire travel direction.

(Construction of Rewinder) First, the structure of the rewinding machine 1 (the yarn winding machine of the present invention) of the present embodiment will be described with reference to FIG. 1 . FIG. 1 is a schematic view of the rewinder 1 viewed from the front. As shown in FIG. 1, the rewinding machine 1 is provided with the wire feeding part 11, the winding part 12, the control apparatus 13 (control part of this invention), etc. The rewinding machine 1 is for unwinding the yarn Y from the yarn feeding package Ps supported by the yarn feeding section 11, and then winding the yarn Y around the winding bobbin Bw by the winding section 12 to form the winding package Pw . More specifically, the rewinding machine 1 is used for, for example, rewinding the yarn Y wound on the yarn feeding package Ps more neatly, or for forming the winding package Pw of a desired density.

The yarn feeder 11 drives the yarn feeding package Ps formed by winding the yarn Y on the yarn feeding bobbin Bs to rotate, and unwinds the yarn Y from the yarn feeding package Ps. The wire feeding part 11 is arranged in front of the lower part of the stand 14 (refer to FIG. 2( a )). The wire feeding part 11 mainly includes a support table 21 , an unwinding motor 22 (the unwinding drive part of the present invention), a direction changing guide 23 (the direction changing part of the present invention), and a wire guide 24 . The wire feeding section 11 drives the wire feeding package Ps rotatably supported by the support table 21 to rotate by the unwinding motor 22, thereby unwinding the wire Y, and passing the wire Y through the direction changing guide 23 and the wire guide 24. Y is guided to the downstream side in the yarn advancing direction.

The support table 21 is a table mounted on the front surface of the lower part of the machine table 14 . The support stand 21 rotatably supports the yarn feeding package Ps so that the axial direction of the yarn feeding package Ps is parallel to the vertical direction. The unwinding motor 22 rotates and drives the yarn feeding package Ps in the direction of unwinding the yarn Y. The unwinding motor 22 is, for example, a general AC motor, and is configured so that the number of revolutions per minute can be changed. In this way, the unwinding motor 22 can change the rotational speed of the yarn feeding package Ps. The unwinding motor 22 is electrically connected to the control device 13 . The direction change guide 23 guides the yarn Y unwound from the yarn supply package Ps upward. The direction change guide 23 is arranged on the outer side of the yarn feeding package Ps in the radial direction of the yarn feeding package Ps. The wire guide 24 is used to guide the wire Y guided by the direction changing guide 23 further downstream in the wire traveling direction. The wire guide 24 is arranged, for example, directly above the direction changing guide 23 .

The winding part 12 is provided on the upper part of the machine table 14 (in other words, at least above the wire feeding part 11. In other words, at least on the side of the feeding package Ps in the axial direction of the feeding package Ps). The winding portion 12 includes a carriage arm 31, a winding motor 32 (winding drive portion of the present invention), a traverse guide 33, and the like. The winding section 12 traverses the wire Y by the traverse guide 33, and drives the winding bobbin Bw rotatably supported by the carrier arm 31 to rotate by the winding motor 32, thereby traversing the wire Y. Y is wound around the winding bobbin Bw. As an example, a cylindrical package (cheese package, see FIG. 1 ) is formed by winding the yarn Y on a cylindrical winding bobbin Bw.

The carrier arm 31 is for rotatably supporting the winding bobbin Bw. The carriage arm 31 is supported by the upper portion of the machine table 14 . A bobbin holder (not shown) for holding the winding bobbin Bw is rotatably attached to the bracket arm 31 . The bobbin holder supports the winding bobbin Bw so that the rotation axis of the winding bobbin Bw extends in the left-right direction (in other words, the direction intersecting the axial direction of the yarn feeding package Ps). The winding motor 32 rotates the winding bobbin Bw (winding package Pw) by rotationally driving the bobbin holder. The winding motor 32 is, for example, a general AC motor, and is configured so that the number of revolutions per minute can be changed. In this way, the winding motor 32 can change the rotational speed of the winding bobbin Bw. The winding motor 32 is electrically connected to the control device 13 . The traverse guide 33 is driven back and forth in the axial direction of the winding bobbin Bw by a drive device (not shown), and traverses the wire Y traveling toward the winding bobbin Bw. Moreover, the touch roller 34 is arrange|positioned more downstream than the traverse guide 33 in a thread|yarn advancing direction. The contact roller 34 applies a contact pressure to the surface of the winding package Pw to adjust the shape of the winding package Pw.

A wire guide 35 and a tension sensor 36 are provided between the wire feeding portion 11 and the winding portion 12 in the wire traveling direction. The wire guide 35 is disposed on the downstream side of the wire guide 24 in the direction in which the wire travels, and is disposed on an extension of the rotation axis of the wire feeding package Ps. The wire guide 35 guides the wire Y upward. The tension sensor 36 is disposed between the yarn guide 35 and the winding package Pw in the yarn traveling direction, and detects the tension applied to the yarn Y. The tension sensor 36 is electrically connected to the control device 13 .

The control device 13 includes a CPU, a ROM, a RAM, and the like. The control device 13 uses the CPU to control each part in accordance with the program stored in the ROM based on the parameters and the like stored in the RAM.

In the rewinding machine 1 having the above structure, when the yarn feeding package Ps is rotationally driven by the unwinding motor 22, the yarn Y is unwound from the yarn feeding package Ps. The speed at which the yarn Y is unwound, that is, the unwinding speed (set as V1), is mainly determined by the rotation speed and diameter of the yarn feeding package Ps. The yarn Y unwound from the yarn feeding package Ps is guided by the yarn guide 24 above the direction changing guide 23 (on the side of the guiding direction of the present invention) through the direction changing guide 23 . In the present embodiment, the guiding direction of the wire Y by the direction changing guide 23 is parallel to the vertical direction (refer to FIG. 2( a )). Furthermore, the wire Y is directed toward the winding portion 12 via the wire guides 24 and 35 and the tension sensor 36 . The yarn Y is wound around the winding bobbin Bw which is rotationally driven by the winding motor 32 while being traversed by the traverse guide 33 . The speed at which the yarn Y is wound, that is, the winding speed (referred to as V2) is mainly determined by the rotational speed and diameter of the winding package Pw. As described above, the winding package Pw (winding operation) is formed.

(detailed structure of the wire feeder) Next, the detailed structure of the wire feeding part 11 is demonstrated using FIG.2 and FIG.3. FIG. 2( a ) is a left side view of the wire feeding part 11 . FIG. 2( b ) is an explanatory diagram showing the state of the driven movement of the direction changing guide 23 . FIG. 3( a ) is a plan view of the wire feeding part 11 . Fig. 3(b) is an explanatory diagram showing a state in which the yarn Y is guided by a bar guide 42, and is a schematic view after Fig. 2(a) is unwound along the circumferential direction of the yarn feeding package Ps.

As shown in FIG. 2( a ), the wire feeding part 11 is further provided with a rail member 41 and a guide rod 42 in addition to the aforementioned support table 21 , the unwinding motor 22 , the direction changing guide 23 and the wire guide 24 (the present invention the isolation part) and the position sensor 43 (the position detection part of the present invention).

The rail member 41 guides the direction changing guide 23 movably. As shown in FIG. 2( a ), the rail member 41 is a member extending linearly in the vertical direction. The rail member 41 is arranged on the outer side of the wire feed package Ps in the radial direction of the wire feed package Ps, and the lower end of the rail member 41 is fixed to the support base 21 . The rail member 41 extends, for example, below the lower end surface of the wire feed package Ps, and extends above the upper end surface of the wire feed package Ps. The extending direction of the rail member 41 is the moving direction in which the direction changing guide 23 is moved.

The direction change guide 23 will be described in more detail. As shown in FIG. 2( a ), the direction changing guide 23 includes a main body portion 44 that moves along the rail member 41 , and a contact portion 45 that contacts the wire Y and guides the wire Y. The main body portion 44 is formed with a through hole 46 having a shape similar to the cross section of the rail member 41 perpendicular to the extending direction. The rail member 41 is inserted through the through hole 46 . In other words, the main body portion 44 is fitted to the rail member 41 with play, for example, so as to be freely movable in the extending direction of the rail member. Alternatively, for example, the main body portion 44 may be smoothly slid relative to the rail member 41 , and the inner peripheral surface of the through hole 46 of the main body portion 44 may be in contact with the peripheral surface of the rail member 41 over the entire circumference. The contact portion 45 is, for example, formed integrally with the body portion 44 or fixed to the body portion 44 , and moves integrally with the body portion 44 . In this way, the direction changing guide 23 is guided movably along the rail member 41 (refer to FIG. 2( b )). More details will be described later.

The guide rod 42 is used to ensure a sufficient length of the yarn passage between the yarn feeding package Ps and the direction changing guide 23 in the yarn traveling direction. The guide rod 42 is, for example, a round bar-shaped member extending in the vertical direction. In the present embodiment, two guide rods 42 are provided (guide rods 47 and 48 in this order from the upstream side in the wire advancing direction), but the number of the guide rods 42 is not limited to this. The guide rod 42 is disposed outside the wire feeding package Ps in the radial direction of the wire feeding package Ps. The lower end of the guide rod 42 is fixed to the support table 21 . The extending direction of the guide rod 42 is parallel to the axial direction of the wire feeding package Ps. The contact portion of the guide rod 42 with the wire extends in the axial direction of the wire feeding package Ps (see FIGS. 2( a ) and 3 ( b )). The guide rod 42 extends below the lower end surface of the wire feeding package Ps, and extends above the upper end surface of the wire feeding package Ps. That is, the guide rod 42 extends at least from the position of one end of the wire feeding package Ps to the position of the other end in the axial direction of the wire feeding package Ps.

By arranging such a guide rod 42, the wire Y after unwinding from the wire feeding package Ps is drawn between the surface connecting the wire feeding package Ps and the guide rod 42 (the guide rod 47 on the upstream side in the wire traveling direction). It travels in a tangential manner (refer to FIG. 3( a )). More specifically, the wire Y is advanced from the pull-out point 102 toward the guide rod 47 . The wire Y reaches the direction changing guide 23 via the guide rods 47 and 48 .

In the yarn traveling direction, the yarn Y traveling between the yarn feeding package Ps and the direction changing guide 23 traverses in the axial direction of the yarn feeding package Ps with the direction changing guide 23 as a fulcrum (see Fig. 3(b) arrow 103). The traverse angle of the wire Y with the direction changing guide 23 as a fulcrum is set as the traverse angle θ1. If the guide rod 42 is not provided, the position of the pull-out point 102 is close to the direction changing guide 23, the traverse angle θ1 is increased, and the length of the yarn path from the yarn feeding package Ps to the direction changing guide 23 varies. get bigger. In this embodiment, since the guide rod 42 is provided, the yarn path from the yarn feeding package Ps to the direction changing guide 23 is long, and the traverse angle θ1 is reduced. Therefore, the length variation of the thread channel as described above can be suppressed.

The position sensor 43 is used to detect the position in the moving direction of the direction changing guide 23 . The position sensor 43 is, for example, an optical sensor having a light-emitting portion and a light-receiving portion not shown. The position sensor 43 is arranged outside the movement range of the direction changing guide 23 and is fixed to the support table 21 . The position sensor 43 emits light from the light emitting part, and detects the light reflected by the direction changing guide 23 by the light receiving part, thereby detecting the distance between the direction changing guide 23 and the position sensor 43 (set to D. Refer to Figure 2(a)). The position sensor 43 is electrically connected to the control device 13 , and transmits information about the above-mentioned distance to the control device 13 .

(the details of the direction change guide) The direction change guide 23 will be described in more detail. If the moving direction of the direction changing guide 23 is greatly inclined with respect to the above-mentioned guiding direction (the direction in which the wire Y is guided by the direction changing guide 23 ), the following problems may occur. That is, when the direction changing guide 23 moves greatly, the wire on the downstream side in the wire advancing direction of the direction changing guide 23 tends to swing greatly due to the driven movement of the direction changing guide. Therefore, if the member is arranged in the vicinity of the wire passage, there is a possibility that the wire Y and the member may interfere. Therefore, in the present embodiment, as shown in FIG. 2( a ), the moving direction of the direction changing guide 23 is parallel to the guide direction (up-down direction). In other words, the rail member 41 extends in the up-down direction, and the direction changing guide 23 is movable in the up-down direction along the rail member 41 . In this way, as shown in FIG. 2( b ), even if the direction changing guide 23 is moved, the horizontal movement of the wire Y traveling on the downstream side in the wire advancing direction of the direction changing guide 23 can be suppressed. In other words, the thread Y on the downstream side in the thread advancing direction of the direction changing guide 23 can be suppressed from rolling (that is, changing the thread path).

The direction change guide 23 is acted upon by gravity (predetermined force of the present invention. Refer to arrow 101 in Figs. 2(a) and (b) ). As described above, the direction changing guide 23 is movable in the vertical direction along the rail member 41 . That is, the direction changing guide 23 is in a state of being suspended in the middle portion of the wire Y in the wire traveling direction. The yarn Y on the upper side (the downstream side in the yarn traveling direction) of the direction changing guide 23 is always drawn downward (the other side in the guiding direction of the present invention) by the direction changing guide 23 . Tension is imparted to the yarn Y in this way. The strength of the tension of the wire Y is roughly determined by the weight of the direction changing guide 23 . In other words, the strength of the tension is changed according to the weight of the direction changing guide 23 . For example, by attaching a weight (not shown) to the direction changing guide 23, the magnitude of the gravitational force acting on the direction changing guide 23 can be changed, and the magnitude of the tension applied to the yarn Y can be changed.

As described above, the direction changing guide 23 has the main body portion 44 and the contact portion 45 , and is movably movable along the rail member 41 . That is, the direction change guide 23 has a simpler structure than, for example, a dancer roller connected to a general dancer arm. Therefore, the mass (inertial mass) of the member that is driven to move is small, and the followability is good. The weight of the direction change guide 23 is, for example, 5 to 10 g.

The moving direction of the direction changing guide 23 is parallel to the axial direction of the feed package Ps. If the moving direction is inclined with respect to the axial direction, when the direction changing guide 23 moves, the distance between the direction changing guide 23 and the surface of the feeding package Ps will change, and the length of the yarn passage will change. In this regard, since the moving direction of the present embodiment is parallel to the axial direction, the length variation of the thread passage as described above can be suppressed.

In the above structure, the yarn Y unwound from the yarn supply package Ps is guided upward by the direction changing guide 23 . In the direction changing guide 23, gravity acts, and the thread Y is always stretched downward by the direction changing guide 23 to be given tension. If the position of the direction changing guide 23 is fixed, the tension will be changed according to the speed difference between the winding speed and the unwinding speed, but in this embodiment, the tension is determined by the direction changing guide 23. It is roughly determined by the size of the stretching force below. Moreover, by making the direction change guide 23 movable, the tension fluctuation of the yarn Y can be suppressed as follows. For example, if the winding speed ( V2 ) of the yarn Y becomes faster than the unwinding speed ( V1 ) due to the traverse of the yarn Y (traversing during unwinding or winding), the direction change guide 23 will The thread Y is pulled upward and driven to move, making the thread channel shorter. As a result, the tension caused by the increase in the tension of the yarn Y can be suppressed. On the contrary, if the winding speed of the wire Y is relatively slow, the wire Y is about to become loose, but as described above, the direction changing guide 23 has a gravitational force, so the direction changing guide 23 is driven downward while moving downward. Filament Y is stretched. As a result, slack due to the decrease in the tension of the yarn Y can be suppressed.

(Position control of direction change guide) Next, an example of the position control of the direction changing guide 23 by the control device 13 will be mainly described with reference to FIG. 4 . 4( a ) is a graph showing the relationship between the speed difference ( V2 - V1 ) of the winding speed ( V2 ) and the unwinding speed ( V1 ) of the yarn Y and the moving speed of the direction changing guide 23 . FIG. 4( b ) is a graph showing the time course of the position of the direction changing guide 23 (to be precise, the distance from the position sensor 43 in the moving direction).

For example, in a state where the rotational speed (revolutions per minute) of the yarn feed package Ps is constant, if the unwinding of the yarn Y progresses and the yarn feed package Ps gradually becomes thinner, the unwinding speed of the yarn Y decreases and the winding speed of the yarn Y decreases. As the winding speed becomes relatively fast, the direction changing guide 23 is pulled upward by the wire Y and is driven to move. As shown in FIG. 4( a ), as the value of V2 - V1 increases, the moving speed (ΔD/Δt) of the direction changing guide 23 increases. At this time, if the direction changing guide 23 moves to the outer side (upper) in the axial direction of the wire feeding package Ps than the upper end face of the wire feeding package Ps, the wire Y will fall off from the upper end face of the wire feeding package Ps, and Doubts that make silk Y unable to travel properly. In other words, in the axial direction of the yarn feeding package Ps, if the distance (D) between the position sensor 43 and the direction changing guide 23 becomes larger than the distance (Da) between the position sensor 43 and the upper end surface of the yarn feeding package Ps ) longer, the above problem occurs. Further, the same problem occurs when the distance between the position sensor 43 and the direction changing guide 23 becomes shorter than the distance (Db) between the position sensor 43 and the lower end face of the wire feeding package Ps. Then, the control device 13 (see FIG. 1 ) controls the unwinding motor 22 so that the direction changing guide 23 is always positioned inward in the axial direction of the feeding package Ps, for example, as follows, thereby controlling the direction changing guide 23 Location. As a control method, for example, general PID (proportional-integral-derivative) control can be used.

As an example, the control device 13 stores information on the target position (target distance) in the up-down direction of the direction changing guide 23 . The target distance is, for example, a value in the middle of the above-mentioned Da and Db (see FIG. 4( b )). As an initial state, the unwinding speed and the winding speed of the yarn Y are substantially equal, and the direction changing guide 23 is substantially stationary at the target position, and the winding operation of the yarn Y is performed. Then, the feeding package Ps becomes thinner and the unwinding speed becomes slower (V2-V1>0). When the position sensor 43 detects that the direction change guide 23 has moved above the target position, the control device 13 The unwinding motor 22 is controlled to increase the rotational speed of the feed package Ps. In this way, the unwinding speed is relatively increased (V2-V1<0), and the direction changing guide 23 is moved downward. On the contrary, when the position sensor 43 detects that the direction changing guide 23 has moved lower than the target position, the control device 13 reduces the rotation speed of the feeding package Ps and reduces the unwinding speed. In this way, the unwinding speed is relatively slow, and the direction changing guide 23 is moved upward. In this way, the control device 13 controls the unwinding motor 22 according to the detection result of the position sensor 43 to perform feedback control of the position of the direction changing guide 23 . In this way, the position of the direction changing guide 23 is brought close to the target position (see FIG. 4( b )).

As described above, the angle formed by the moving direction of the direction changing guide 23 and the guide direction is reduced. Therefore, compared with the structure in which the moving direction and the guiding direction are perpendicular to each other or nearly perpendicular to each other, the wire Y traveling on the downstream side of the wire traveling direction of the direction changing guide 23 can be suppressed from swaying due to the driven movement of the direction changing guide 23 (change the thread channel). Therefore, the variation of the thread path caused by the driven movement of the direction changing guide 23 can be suppressed.

In addition, the moving direction of the direction changing guide 23 is parallel to the up-down direction. Therefore, the direction changing guide 23 can be moved by the action of gravity. Therefore, compared with the structure in which the direction change guide 23 is urged|biased by a spring etc., the simplification of a structure and cost reduction can be aimed at. Furthermore, a stable force due to gravity can be applied to the direction changing guide 23, so that the traveling yarn Y can be drawn stably. In this way, tension can be stably imparted to the running yarn Y.

In addition, the direction change guide 23 is guided movably by the rail member 41 . Therefore, the structure of the direction changing guide 23 can be simplified and the inertial mass can be reduced compared to the case of using, for example, a dancer roller connected to a general dancer arm as the direction changing guide 23 . Therefore, the followability of the direction change guide 23 can be improved.

Furthermore, in the structure in which the rail member 41 extends in the up-down direction, and the direction changing guide 23 is driven to move in a direction parallel to the up-down direction, the wire Y is moved directly downward by the gravity acting on the direction changing guide 23 . stretch. Therefore, the tension applied to the yarn Y can be roughly determined by the weight of the direction changing guide 23, and the desired tension can be easily applied to the yarn Y with a simple structure.

In addition, the moving direction of the direction changing guide 23 is parallel to the axial direction of the yarn feeding package Ps. Therefore, when the direction changing guide 23 is moved, the variation of the distance between the direction changing guide 23 and the surface of the wire feeding package Ps can be suppressed. Therefore, the length variation of the thread channel can be suppressed.

In addition, the axial direction of the feeding package Ps is parallel to the up-down direction. Therefore, the deflection of the rotating shaft of the feeding package Ps due to gravity can be prevented. Therefore, the instability of the rotation of the feeding package Ps can be suppressed.

In addition, a guide rod 42 is provided between the yarn feeding package Ps and the direction changing guide 23 in the yarn traveling direction. That is, the yarn Y unwound from the yarn feeding package Ps travels toward the direction changing guide 23 via the guide rod 42 . In this way, even if the direction changing guide 23 is not arranged away from the feeding package Ps, the yarn path from the surface of the feeding package Ps to the direction changing guide 23 can be lengthened. In addition, the guide rod 42, since its contact portion with the wire Y extends in the axial direction of the wire feeding package Ps, the wire Y can be smoothly slid in the axial direction. Therefore, it is possible to reduce the traverse angle θ1 of the yarn Y after unwinding while suppressing the enlargement of the apparatus.

In addition, the control device 13 controls the unwinding motor 22 according to the detection result generated by the position sensor 43 . In this way, by actively changing the speed difference between the winding speed and the unwinding speed of the wire, the direction changing guide 23 can be actively moved. Therefore, for example, the position of the direction changing guide 23 can be controlled by performing feedback control such that the position of the direction changing guide 23 is brought close to the target position. Therefore, the large movement of the direction changing guide 23 can be suppressed.

In addition, the position sensor 43 is an optical sensor, and can optically detect the position of the direction changing guide 23 . Even if the structure of the magnetic sensor for magnetically detecting the position of the direction changing guide 23 is adopted, the direction changing guide 23 must be formed of a conductor such as metal or a conductor must be attached to the direction changing guide 23 . Therefore, the mass of the direction changing guide 23 increases, and there is a possibility that the direction changing guide 23 becomes difficult to follow and move. In addition, in a structure using, for example, a contact-type position sensor, due to the frequent movement of the direction change guide 23, the sensor is easily worn out, and there is a concern that the sensor deteriorates prematurely. In the present embodiment, an increase in the mass of the direction changing guide 23, premature deterioration of the sensor, and the like can be suppressed.

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

(1) In the aforementioned embodiment, the moving direction is set to be parallel to the guiding direction, but the present invention is not limited to this. For example, as shown in FIG. 5, in the wire feeding part 11a of the rewinding machine 1a, the guide direction and the moving direction may be inclined to each other. The angle θ2 formed between the moving direction and the guiding direction is, for example, 45 degrees or less. According to such a structure, compared with a structure in which the moving direction and the guiding direction are perpendicular to each other or nearly perpendicular to each other, the wire Y can be suppressed from swinging (variation of the wire passage) due to the driven movement of the direction changing guide 23 .

(2) In the above-described embodiments, the moving direction of the direction changing guide 23 is set to be parallel to the vertical direction, but the present invention is not limited to this. The moving direction may also have an inclination angle with respect to the up-down direction. That is, in the structure in which the direction changing guide 23 is moved by the gravity acting on the direction changing guide 23, the moving direction only needs to have a vertical component. Alternatively, the direction changing guide 23 may be biased by a spring or the like. In such a structure, even if the moving direction is substantially parallel to the horizontal direction, the direction changing guide 23 can be urged.

(3) In the above-described embodiments, the direction changing guide 23 is used as the direction changing portion of the present invention, but the present invention is not limited to this. For example, a dancer roller attached to a general dancer arm may also be used. In this case, the dancer roller corresponds to the direction changing portion of the present invention.

(4) In the above-described embodiments, the moving direction of the direction changing guide 23 is parallel to the axial direction of the yarn feeding package Ps, but it is not limited to this. The moving direction may have an inclination angle with respect to the axial direction.

(5) In the above-mentioned embodiments, the axial direction of the feed package Ps is parallel to the vertical direction, but the present invention is not limited to this. The axial direction may have an inclination angle with respect to the vertical direction.

(6) In the above-described embodiments, the guide rod 42 is arranged between the yarn feeding package Ps and the direction changing guide 23 in the yarn advancing direction, but the present invention is not limited to this. For example, instead of the guide bar 42, a guide roller (not shown) extending at least from the position of one end to the position of the other end of the feed package Ps may be provided in the axial direction of the feed package Ps. Alternatively, instead of the guide rod 42, as shown in FIG. 6, a guide rail 51 extending along the axial direction of the wire feeding package Ps is provided in the wire feeding portion 11b of the rewinding machine 1b, and is movable along the guide rail 51. The driven roller 52 may also be used. That is, the yarn Y may be guided by the driven roller 52 from the yarn feeding package Ps to the direction changing guide 23 . Even with such a configuration, a sufficiently long thread path can be secured from the thread feed package Ps to the direction changing guide 23, and the thread Y can be smoothly slid in the axial direction. In this modification, the driven roller 52 corresponds to the spacer of the present invention. Alternatively, the driven roller 52 may extend toward the axial direction of the yarn feeding package Ps (that is, the yarn Y may be moved along the peripheral surface of the driven roller 52 in the axial direction of the driven roller 52 ). ). As described above, the spacer portion of the present invention can also be configured to be driven to move in the axial direction of the wire feeding package, and/or the portion in contact with the wire extends in the axial direction.

(7) In the above-described embodiments, the control device 13 controls the unwinding motor 22 so that the direction changing guide 23 is brought close to the target position, but it is not limited to this. That is, the control device 13 should just control the position of the direction changing guide 23 so that the direction changing guide 23 is positioned on the inner side in the axial direction of the yarn feeding package Ps. As an example, the control device 13 may store the allowable range of the movement of the direction changing guide 23 . Then, the control device 13 controls the unwinding motor 22 to adjust the winding speed and the unwinding speed so that the direction changing guide 23 is within the allowable range when the direction changing guide 23 moves outside the allowable range, for example. Speed difference change.

(8) In the above-described embodiments, the control device 13 controls the unwinding motor 22 to change the speed difference between the winding speed and the unwinding speed, but it is not limited to this. The control device 13 may also change the speed difference by controlling the winding motor 32 . Alternatively, the control device 13 may control both the unwinding motor 22 and the winding motor 32 .

(9) In the above-described embodiments, an optical sensor is used as the position sensor 43, but it is not limited to this. As the position sensor, for example, a magnetic sensor and a touch sensor can also be used.

(10) As shown in FIG. 7 , the rewinding machine 1 c may be provided with a feed roller 61 (a thread feed roller of the present invention) and a roller drive motor 62 for rotationally driving the feed roller 61 . The feed roller 61 is disposed, for example, between the wire guide 35 and the tension sensor 36 in the wire travel direction (in other words, on the downstream side of the direction change guide 23 in the wire travel direction). The feed roller 61 is rotated and driven by the roller drive motor 62 to feed the thread Y to the downstream side. With such a structure provided with the feed roller 61, if the yarn Y is loosened on the immediately upstream side of the feed roller 61 with respect to the yarn traveling direction, the thread Y tends to slide on the peripheral surface of the feed roller 61, and there is a possibility that There is a concern that the yarn Y is normally fed to the downstream side. Even with such a structure, the yarn Y is always drawn downward (that is, on the upstream side in the yarn traveling direction) by the direction changing guide 23, so that it can be suppressed that the yarn Y is more upstream than the yarn feeding roller 61 in the yarn traveling direction. Silk Y is loose.

(11) As shown in FIG. 8 , in the yarn feeding section 11d of the rewinding machine 1d, the support table 70 (package support section of the present invention) is configured to be movable in the front-rear direction (the cross direction of the present invention), for example. You can also. That is, the wire feeding part 11d may be provided with two side panels 71 and 72 protruding forward from the left and right ends of the machine table 14, and slide rails 73 and 74 attached to the side panels 71 and 72, respectively. The support table 70 is arranged in front of the machine table 14 and is supported by the slide rails 73 and 74 so as to be movable in the front-rear direction. In other words, the machine table 14 is arranged behind the support table 70 (one side in the intersecting direction of the present invention). In this way, the support table 70 becomes the unwinding position (refer to the solid line in FIG. 8 ) when the yarn Y is unwound from the yarn supplying package Ps, and the unwinding position (on the other side in the intersecting direction of the present invention) ) between the replacement positions (refer to the two-dot chain line in Figure 8). Therefore, the space for the replacement work of the wire feed package Ps can be widely secured, and the replacement work of the wire feed package Ps can be facilitated. In addition, the intersecting direction does not necessarily have to be orthogonal to the vertical direction (vertical direction). For example, the support stand 70 may be configured to be movable in a forward and inclined direction.

(12) The present invention can also be applied to wire winding machines other than rewinding machines. That is, the present invention can be applied to various types of yarn winding machines that unwind the yarn from the yarn feeding package and then wind the yarn on the winding bobbin to form the winding package.

(13) In the aforementioned embodiment, the cylindrical package is formed by winding the yarn Y on the cylindrical winding bobbin Bw, but the present invention is not limited to this. For example, a cone-shaped package may be formed by winding the wire Y on a cone-shaped or truncated-cone-shaped winding bobbin Bw. When the winding package Pw having a non-uniform diameter is wound in the axial direction of the winding bobbin Bw like a conical package, the control device 13 controls the unwinding motor 22 and the winding motor 32 to control the direction changing guide 23 The location, as explained below, is useful. That is, in the structure in which the winding bobbin Bw is rotationally driven by the winding motor 32, since the winding speed of the yarn Y is different between the large-diameter side portion and the small-diameter side portion of the conical package, the direction changing guide 23 The location is easy to change. Therefore, there is a possibility that the yarn Y is likely to fall off from the end face of the yarn feeding package Ps. Therefore, when a conical package with uneven package diameters is formed, by controlling the position of the direction changing guide 23 to suppress the large movement of the direction changing guide 23, it is possible to more effectively prevent the wire Y from passing from the feeding package Ps The end face falls off.
