Description

False twist processing machine

The invention relates to a false twist processing machine.

Patent Document 1 describes a false twisting machine that performs false twisting on a yarn made of synthetic fiber. The false-twisting machine is provided with a plurality of false-twisting devices arranged along a predetermined longitudinal direction of the machine body, and each imparts a twist to a plurality of traveling yarns. As the false twisting device, for example, a triaxial friction-type false twisting device (triaxial false twisting device) described in Patent Document 2 is often used. The three-axis false twisting device has three rotational axes extending along a predetermined axial direction that is substantially orthogonal to the longitudinal direction of the machine body, and a plurality of friction discs (disc members) provided on each of the rotational axes. The centers of the three rotation axes form the vertices of a virtual triangle when viewed from the axial direction. When the disc member is rotated in a predetermined direction, twist is imparted to the yarn traveling inside the triangle while in contact with the disc member.

Here, in order to process more yarns while suppressing the enlargement of the false twisting machine, it is considered to install it instead of the three-axis false twisting device. A five-axis false twisting device having five rotating axes and capable of imparting twist to two yarns at a time (see Patent Document 3). The five-axis false twisting device is provided with a first false twisting section that imparts twist to the first yarn and a second false twisting section that imparts twist to the second yarn. These false twisting sections share one of the five rotation axes. One serves as a common axis of rotation. That is, in the five-axis false twisting device, when viewed from the axial direction, two virtual triangles are formed with a common rotation axis as a common vertex, and two yarns running inside these triangles are given twists. In this way, using the five-axis false twisting device can reduce the number of rotating shafts compared to a configuration in which two three-axis false twisting devices are provided. Therefore, more yarns can be processed while suppressing an increase in the size of the device.

In the above-mentioned five-axis false twisting device, yarn needs to be hung in the first false twisting part and the second false twisting part. Specifically, it is necessary to carry out an operation of taking in the yarn from between two predetermined rotation axes to the inside of the triangle in each of the first false-twisted portion and the second false-twisted portion. Hanging yarn is generally performed by an operator located in a working space extending along the longitudinal direction of the machine body. Here, in the 1st holiday When one of the twisting part and the second false twisting part is arranged on the side (the back side) farther away from the working space than the other, the yarn hooking operation of the false twisting part on the back side becomes extremely difficult. Therefore, it is necessary to arrange the first false twisting part and the second false twisting part so as to be aligned along the longitudinal direction of the body so that both the first false twisting part and the second false twisting part face the work space.

Furthermore, in order to hook the yarn to each false-twisted portion, it is required to have a device structure in which the yarn is passed between two rotating shafts arranged on the outer side of the body in the longitudinal direction (details will be described in the embodiments described later). ). In this configuration, when yarn is hung up on a certain five-axis false twisting device, there is a concern that the working space between the five-axis false twisting device adjacent to the machine body in the longitudinal direction will become narrower, and the yarn hanging operation will be reduced. Questions that will become more difficult.

An object of the present invention is to facilitate yarn hooking operations in a false twisting machine in which five-axis false twisting devices are arranged in a row along the longitudinal direction of the machine body.

The false twisting machine of the first invention is equipped with a plurality of five-axis false twisting devices capable of imparting twist to two yarns at a time using a plurality of disk members, and the plurality of five-axis false twisting devices are along a predetermined longitudinal direction of the body. Arranged in an array, the plurality of disc members are provided on five rotational axes extending in an axial direction intersecting the longitudinal direction of the machine body, and a plurality of five-axis false twisting devices are formed along the longitudinal direction of the machine body. A working space for yarn hanging, characterized in that each five-axis false twisting device is equipped with: a first false twisting part having a vertex of a virtual first triangle among the five rotation axes when viewed from the axial direction. Two first individual rotation axes and a common rotation axis at each point provide twist to the first yarn running inside the first triangle; and a second false twist portion has one of the five rotation axes. The two second individual rotation axes that form the vertices of the virtual second triangle when viewed in the axial direction and the one common rotation axis impart twist to the second yarn traveling inside the second triangle. One individual rotating shaft and the two second individual rotating shafts are arranged on opposite sides to each other across the common rotating shaft in the longitudinal direction of the body, and the first false twisting portion is for the first yarn to pass from The space between the two first individual rotating shafts enters the inside of the first triangle and the yarn is caught. The second false twisting portion is for the second yarn to enter the above-mentioned first triangle from between the two second individual rotating shafts. The yarn is hung on the inner side of the two triangles. One of the two first individual rotating shafts is the first movable shaft. The first movable shaft is arranged closer to the working space than the other of the two first individual rotating shafts. on the near side, and can move between the first operating position when the five-axis false twisting device is operating and the first yarn hanging position which is closer to the near side than the first operating position, and the two second individual One of the rotating shafts is a second movable shaft. The second movable shaft is disposed closer to the body than the other of the two second individual rotating shafts and is capable of operating in a third position when the five-axis false twisting device is operated. Move between the 2nd action position and the 2nd yarn hanging position which is closer to the body side than the 2nd action position.

In the present invention, in the five-axis false twisting device, the first individual rotation axis of the first false twisting part and the second individual rotation axis of the second false twisting part are arranged mutually across the common rotation axis in the longitudinal direction of the body. Opposite side. In other words, the first false twisting part and the second false twisting part are arranged side by side along the longitudinal direction of the body. Furthermore, one of the two first individual rotating shafts is movable between the first operating position and the first yarn hanging position closer to the body than the first operating position. This allows the gap between the two first individual rotating shafts to be increased when the yarn is hung on the first false twist portion. Therefore, even in a configuration in which a plurality of five-axis false twisting devices are arranged in a row along the longitudinal direction of the machine body, yarn can be easily hung from the work space. Similarly, since one of the two second individual rotating shafts can move between the second operating position and the second yarn hooking position, when the yarn is hooked to the second false twisting portion, the two second individual rotations can be increased. clearance between shafts. As described above, in the false twisting machine in which the five-axis false twisting devices are arranged in a row along the longitudinal direction of the machine body, the yarn hanging operation can be easily performed.

A false twisting machine according to a second aspect of the invention is the first aspect of the invention, wherein the first movable shaft and the second movable shaft are swingable about the common rotation axis as a swing axis center.

In a configuration in which the distance between the first movable shaft and the second movable shaft and the common rotation axis changes when the first movable shaft and the second movable shaft move, for example, it is desired to interpose a member ( belts, gears, etc.), the following obstacles may occur. For example, if the distance changes while the belt is sandwiched, there is a concern that the belt may become loose or be damaged due to excessive tension. In addition, if the distance changes with the gears interposed therebetween, there is a concern that the meshing accuracy may deteriorate when the gears are meshed again.

In the present invention, since the first movable shaft and the second movable shaft can swing about the common rotation axis as the swing axis center, the movable shaft can be moved without changing the distance between the movable shaft and the common rotation axis. move. Therefore, it is possible to avoid the above-mentioned obstacles.

The false twisting machine of the third invention is the first or second invention, wherein the first false twisting part has a first yarn guide, and the first yarn guide is arranged among the plurality of disc members. on the upstream side of the most upstream disc member in the first yarn traveling direction in which the first yarn travels, the second false twist portion has a second yarn guide, and the second yarn guide is disposed Among the plurality of disc members, the first yarn guide and the second yarn guide are further upstream of the most upstream disc member in the second yarn traveling direction in which the second yarn travels. At least one of the members is a movable yarn guide member whose position can be adjusted relative to the other member.

Generally, in each false twist portion, a plurality of disc members are arranged to draw a spiral. Here, the yarn path of the first yarn guided by the first yarn guide and the yarn path of the second yarn guided by the second yarn guide differ depending on which rotation axis the most upstream disc member in the yarn traveling direction is installed. 2The yarn path of the yarn may vary. In this case, if the yarn path of the first yarn is greatly different from that of the second yarn, the twisting method of the first yarn will be different from that of the second yarn due to the difference in the bending angle of the yarn. The twisting methods of the two yarns are different from each other. As a result, the yarn quality of the first yarn and the yarn quality of the second yarn may become uneven.

In the present invention, by adjusting the position of the movable yarn guide, it is possible to suppress the difference between the yarn path of the first yarn guided by the first yarn guide and the yarn path of the second yarn guided by the second yarn guide. is smaller. Therefore, unevenness in yarn quality between the first yarn and the second yarn can be suppressed.

The false twisting machine of the fourth invention is, in the above-mentioned third invention wherein the first yarn guide member and the second yarn guide member are arranged aligned along the longitudinal direction of the body, and the movable yarn guide member can intersect with the longitudinal direction of the body when viewed from the axial direction. direction of movement.

For example, in a structure in which one of the first yarn guide and the second yarn guide is moved in the longitudinal direction of the body, there is a case where the first yarn guide and the second yarn guide are moved in order to avoid interference with the other of the first yarn guide and the second yarn guide. Worry about narrowing range of motion. In the present invention, it is possible to suppress interference between two yarn guide members and widen the movable range of the movable yarn guide member, thereby effectively adjusting the yarn path.

A fifth invention provides a false twisting machine according to any one of the first to fourth inventions, wherein the five-axis false twisting device transmits power from a drive source to the five rotational axes. An intermediate shaft that is one of three fixed rotational shafts in addition to the first movable shaft and the second movable shaft, and has an intermediate shaft that transmits the power of the driving source from the intermediate shaft to the remaining two of the three fixed rotational shafts. shared belt.

In order to use one driving source to rotationally drive multiple rotating shafts, generally speaking, it is better to use a belt with less noise and vibration to transmit the power of the driving source. However, if the number of belts is simply increased based on the number of rotating shafts, the portion of the rotating shaft to which the belt is hooked increases, so the rotating shaft becomes longer and the device becomes larger in the axial direction. In the present invention, since three fixed rotation shafts can be collectively driven using a common belt, the number of belts can be kept small. Therefore, it is possible to suppress the elongation of the rotation shaft and the enlargement of the device.

A sixth invention provides a false twisting machine according to the fifth invention, wherein the intermediate shaft is the common rotation shaft.

According to the positional relationship of the above-mentioned five rotation axes, the common drive shaft is arranged in the center of the five rotation axes in the longitudinal direction of the body. In the present invention, the power of the driving source is first transmitted to the common rotating shaft in the center. Therefore, the five-axis false twisting device can further transmit power to other rotating shafts arranged around the common rotating shaft. Therefore, the structure for power transmission can be simplified.

A seventh invention provides a false twisting machine according to any one of the first to sixth inventions, wherein each five-axis false twisting device has a common driving source for driving the five rotational axes together, Among the above-mentioned five rotating shafts, the rotating shaft not used for yarn processing is provided with a counterweight instead of the above-mentioned disc member.

In the five-axis false twisting device, the first false twisting unit and the second false twisting unit may be used to impart twist to two yarns at a time, and there are also cases where the first false twisting unit and the second false twisting unit are used. A situation where only one yarn is given a twist by either side. In this way, when twist is given to only one yarn, from the viewpoint of cost reduction, etc., it is preferable to remove unnecessary disc members from the rotating shaft that is not used for yarn processing. However, by simply removing the disc member from a part of the rotation axis of a certain five-axis false twisting device, the load on the common drive source of this five-axis false twisting device is the same as the load on the common drive source on other five-axis false twisting devices. The load of the source becomes smaller. Then, in the five-axis false twisting device in which a part of the disc member was removed, the five rotation axes unexpectedly rotated rapidly. As a result, there is a concern that the yarn quality of the yarn processed by this five-axis false twisting device is greatly different from the yarn quality of the yarn processed by other five-axis false twisting devices.

In the present invention, since the counterweight is provided in place of the unnecessary disk member, the counterweight becomes a load and can prevent the rotating shaft from unexpectedly rotating rapidly. Therefore, by using a member that is cheaper than a circular plate member as a counterweight, it is possible to suppress an increase in cost and suppress variation in yarn quality between five-axis false twisting devices.

An eighth invention is a false twisting machine according to any one of the first to seventh inventions, wherein the disc member provided on the common rotation axis forms a contact portion with the yarn. The abrasion resistance is higher than the abrasion resistance of a member of the disc member provided on a rotation axis other than the common rotation axis that forms a contact portion with the yarn.

The disc member provided on the rotation axis other than the common rotation axis is in contact with only the first yarn or the second yarn. On the other hand, the disc member provided on the common rotation axis is in contact with both the first yarn and the second yarn. Therefore, the disk member provided on the common rotation axis may wear earlier than the disk members provided on other rotation shafts. In this case, there is a concern that only the disk member provided on the common rotation axis needs to be replaced early, and the man-hours for the replacement work may increase. In the present invention, the wear resistance of the disc member provided on the common rotating shaft is higher than that of other disc members, so that premature wear of only the disc member provided on the common rotating shaft can be suppressed. Therefore, it is possible to avoid the necessity of early replacement of only a part of the disc member.

A ninth aspect of the invention is the false twisting machine according to any one of the above-mentioned first to eighth inventions, wherein the first false twisting section is arranged in a first yarn traveling direction in which the first yarn travels. The upstream disc member and the second false twisting portion are arranged on the second path where the second yarn travels. The disc member on the most upstream side in the yarn traveling direction is arranged on the same first plane orthogonal to the axial direction, and the first false twist portion is arranged on the most downstream side in the first yarn traveling direction. The disc member on the side and the disc member of the second false twist portion disposed on the most downstream side in the second yarn traveling direction are disposed in the same second plane orthogonal to the axial direction.

In a configuration in which the most upstream disc member in the first yarn traveling direction and the most upstream disc member in the second yarn traveling direction are arranged to be axially offset from each other, at least a part of the rotation shaft is lengthened. necessity. As a result, first, the yarn path of the first yarn and the yarn path of the second yarn may change. If the yarn path of the first yarn is very different from the yarn path of the second yarn, the twisting method of the first yarn and the twisting method of the second yarn will be different from each other due to the difference in the bending angle of the yarn. As a result, the yarn quality of the first yarn and the yarn quality of the second yarn may become uneven. Second, the device may be enlarged in the axial direction. The positional relationship between the most downstream disc member in the first yarn traveling direction and the most downstream disc member in the second yarn traveling direction is also the same. In the present invention, the arrangement of the disc member in the axial direction can be compacted without substantially changing the yarn path of the first yarn and the yarn path of the second yarn. Therefore, it is possible to suppress an increase in the size of the device in the axial direction. In addition, in the present invention, the posture of the yarn path of the first yarn and the posture of the yarn path of the second yarn when viewed from the longitudinal direction of the body can be made closer to the same.

The main body 8, the winding table 9, and the support frame 10 form a working space 22 for the operator to perform operations such as hanging yarn on each device. The yarn path is formed so that the yarn Y mainly travels around the working space 22 .

The false twisting machine 1 has a unit unit called a span (English: span) including a set of main bodies 8 and a winding table 9 arranged to face each other. In one span, each device is configured to simultaneously perform false twisting on a plurality of yarns Y traveling in a state aligned in the longitudinal direction of the machine body. As an example, one winding table 9 is provided with 12 winding devices 21 (see FIG. 3 ). In addition, as will be described later, one winding device 21 can wind one or two yarns Y at the same time. That is, in this embodiment, up to 24 yarns Y can be wound simultaneously in one span. Furthermore, the false twisting machine 1 is arranged symmetrically on the drawing surface with the center line C in the machine width direction of the main body 8 as the axis of symmetry in the span (the main body 8 is common to the left and right spans), and in There are multiple ones arranged in the longitudinal direction of the body.

(Structure of processing department)

The first yarn feeding roller 11 can feed the two yarns Y to the first heating device 13, for example, as shown in FIG. 2, but is not limited to this.

The twist-stopping guide 12 prevents the twist imparted to the yarn Y by the five-axis false twist device 15 described below from propagating further upstream in the yarn traveling direction of the twist-stopping guide 12 . The twist-stop yarn guide 12 is disposed on the downstream side of the first yarn feeding roller 11 in the yarn traveling direction and on the upstream side of the first heating device 13 in the yarn traveling direction. For example, the twist-stopping yarn guides 12 are provided independently with respect to the plurality of yarns Y supplied from the yarn supply part 2, and are arranged in a row in the longitudinal direction of the body.

The first heating device 13 is used to heat the yarn Y sent from the first yarn feeding roller 11, and is installed in the support frame 10 (see FIG. 1).

Each first heating device 13 can heat four yarns Y, for example, as shown in FIG. 2 , but is not limited thereto.

The cooling device 14 is used to cool the yarn Y heated by the first heating device 13 . The cooling device 14 is disposed on the downstream side of the first heating device 13 in the yarn traveling direction and on the upstream side of the five-axis false twisting device 15 in the yarn traveling direction. The cooling device 14 is capable of cooling the yarn Y using an air flow, as described in Japanese Patent Application Laid-Open No. 2011-47074, for example. A plurality of cooling devices 14 are provided for the plurality of yarns Y supplied from the yarn supply part 2, and are arranged in a row along the longitudinal direction of the body.

The doubling device 17 has two interlacing nozzles 31 and 32 (see FIG. 2 ). The doubling device 17 aligns the yarn Y1 and the yarn passing through the interlacing nozzle 31 , for example. Y2 (refer to the left part of the paper in Fig. 2) injects air, and the yarn Y1 and the yarn Y2 are intertwined by air inter-race, thereby performing doubling. In addition, the yarn doubling device 17 can also guide the two yarns Y to the downstream side in the yarn traveling direction without doubling the yarn Y1 and the yarn Y2. In this case, the yarn Y1 passes through the inside of the interlacing nozzle 31, and the yarn Y2 passes through the inside of the interlacing nozzle 32 (see the right part of the paper in Fig. 2).

The fourth yarn feeding rollers 20 are arranged in a row along the longitudinal direction of the machine body. The fourth yarn feeding roller 20 can feed the two yarns Y to the winding device 21, for example, as shown in FIG. 2, but is not limited thereto. The conveying speed of the yarn Y by the fourth yarn feeding roller 20 is slower than the conveying speed of the yarn Y by the third yarn feeding roller 18. The yarn Y is between the third yarn feeding roller 18 and The space between the fourth yarn feeding rollers 20 is relaxed.

In the processing section 3 configured as above, two yarns Y stretched between the first yarn feeding roller 11 and the second yarn feeding roller 16 are processed by a five-axis false twisting device 15. Twist. The twist formed by the five-axis false twist device 15 propagates to the twist-stopping yarn guide 12 but does not propagate to the upstream side of the twist-stopping yarn guide 12 in the yarn traveling direction. The stretched and twisted yarn Y is heated and heat-set by the first heating device 13 and then cooled by the cooling device 14 . Downstream from the five-axis false twisting device 15, the yarn Y is untwisted, but each single fiber remains falsely twisted into a corrugated state by the heat setting described above. Furthermore, the two yarns Y (yarn Y1 and yarn Y2) falsely twisted by the five-axis false twisting device 15 are relaxed between the second yarn feeding roller 16 and the third yarn feeding roller 18 and pass through The yarn device 17 guides the yarns to the downstream side in the yarn traveling direction after the yarns are aligned, or without being aligned. Then, the yarn Y is relaxed between the third yarn feeding roller 18 and the fourth yarn feeding roller 20 and is heat-set by the second heating device 19 . Finally, the yarn Y conveyed from the fourth yarn feeding roller 20 is wound by the winding device 21 to form a winding package Pw.

(Configuration of the winding section)

Next, the structure of the winding part 4 is demonstrated with reference to FIG.2 and FIG.3. The winding unit 4 has a plurality of winding devices 21 for winding the yarn Y around the winding bobbin Bw. Each winding device 21 can wind the yarn Y around one or two winding bobbins Bw, for example, as described in Japanese Patent Application Laid-Open No. 2009-74219. Each winding device 21 includes a fulcrum guide 41 that serves as a fulcrum when the yarn Y is traversed, a traverse device 42 that traverses the yarn Y, and a winding bobbin Bw. A single cradle 43 and a control unit 44 (refer to FIG. 3 ) are supported in a rotatable manner.

As described above, the fulcrum guide 41 is a guide that serves as a fulcrum when the yarn Y is traversed. For example, three fulcrum guides 41 are provided in each winding device 21 so as to be arranged along the longitudinal direction of the machine body (see FIG. 2 ). For example, when guiding the yarn Y that is combined into one yarn by the yarn doubling device 17, the yarn Y is hooked on the fulcrum yarn guide 41 arranged in the center among the three fulcrum yarn guides (see FIG. 2 (left part of paper). In addition, when guiding two yarns Y which are not coupled but are fed as they are, the yarns Y are respectively hooked on two fulcrum yarn guides 41 at both ends among the three fulcrum yarn guides 41 (Refer to the right part of the paper in Figure 2).

The traverse device 42 can traverse the yarn Y using, for example, a traverse guide 45 attached to an endless belt driven reciprocally by a motor. The number of traverse guides 45 attached to the endless belt can be changed according to the number of traversed yarns Y. For example, a traverse guide 45 is provided in the traverse device 42 that traverses the yarn Y that is combined into one yarn Y by the doubling device 17 (see the left part of the paper in FIG. 2 ). In addition, the traverse device 42 that traverses the two yarns Y that are fed as they are without being coupled is provided with two traverse guides 45 (see the right part of the paper in FIG. 2 ). The movement range of the traverse guide 45 can be changed according to the number of traversed yarns Y. Information related to settings such as the number of traversed yarns Y and the movement range of the traverse guide 45 is stored in the control unit 44, for example.

The cradle 43 can rotatably support one or more (1 or 2) winding bobbins Bw (winding packages Pw). In other words, the cradle 43 can The state is switched between a state in which one winding bobbin Bw is supported and a state in which two winding bobbins Bw are supported. One cradle 43 is provided for each of the plurality of winding devices 21 . In addition, a contact roller 46 that comes into contact with the surface of the winding package Pw is disposed immediately upstream of the winding package Pw in the yarn traveling direction. The winding bobbin Bw supported by the cradle 43 is rotationally driven by, for example, a motor (not shown). In this structure, the contact roller 46 in contact with the surface of the take-up package Pw is driven to rotate by friction and applies contact pressure to the take-up package Pw. Alternatively, instead of using a motor to rotate the winding bobbin Bw, the contact roller 46 may be rotated and driven by a motor (not shown). In this structure, the take-up package Pw in contact with the contact roller 46 is driven to rotate by friction.

The control unit 44 controls the operation of the traverse device 42 and the operation of the motor that rotationally drives the winding bobbin Bw. The control unit 44 can change the settings related to the number of yarn Y wound in the winding device 21 . That is, the control unit 44 can wind one yarn Y on one winding bobbin Bw (refer to the left part of the paper in FIG. 2 ) in the first mode and can wind two yarns Y on two winding bobbins Bw, respectively. The operation mode is switched between the second mode of the bobbin Bw (see the right part of the paper in Fig. 2).

In the winding unit 4 configured as above, the yarn Y fed from the fourth yarn feeding roller 20 is wound around the winding bobbin Bw by each winding device 21 to form a winding package Pw. When the two yarns Y are combined by the doubling device 17, the corresponding operation mode of the winding device 21 is set to the first mode. In addition, when the two yarns Y are not aligned but are guided to the downstream side in the yarn traveling direction as they are, the corresponding operation mode of the winding device 21 is set to the second mode.

(Construction of false twisting device)

Next, the structure of the five-axis false twisting device 15 will be described with reference to FIGS. 4 to 7 . Figure 4 is a perspective view of the five-axis false twisting device 15. FIG. 5 is a view of the five-axis false twisting device 15 viewed from a direction orthogonal to the longitudinal direction of the machine body and the axial direction of the rotation shaft 53 (hereinafter referred to as the axial direction) to be described later. (a) and (b) of FIG. 6 are views of the five-axis false twisting device 15 that imparts Z twist to the yarn Y when viewed from the axial direction. (a) and (b) of FIG. 7 are views of the five-axis false twisting device 15 that imparts S twist to the yarn Y when viewed from the axial direction. In FIGS. 6(b) and 7(b) , the disc member 57 to be described later is shown with a chain double-dot line so that the support stands 54 to 56 to be described later are visible. In addition, one side and the other side in the longitudinal direction of the body are defined as shown in FIGS. 4 to 7 . In addition, in the five-axis false twisting device 15, the side close to the working space 22 (see Fig. 1) is defined as the near side (see Figs. 1, 4, 6 and 7), and the side far away from the working space 22 is defined as the near side (see Figs. 1, 4, 6 and 7). One side is defined as the back side (refer to Figures 4, 6 and 7). In addition, illustration of the yarn guide 61 described later is omitted in FIGS. 6(a) to 7(b).

The five-axis false twisting device 15 can twist two yarns Y (yarn Y1 and yarn Y2) in the same direction (implement Z twist or S twist) at one time. That is, as shown in FIGS. 4 to 7 , the five-axis false twisting device 15 is provided with a first false twisting part 51 that imparts twist to the yarn Y1 and a second false twisting part 52 that imparts twist to the yarn Y2. A plurality of five-axis false twisting devices 15 are arranged in the longitudinal direction of the machine body (see Figure 2).

As shown in FIGS. 4 to 7 , the five-axis false twisting device 15 is a component of the first false twisting part 51 and the second false twisting part 52 and has five rotations. The shaft 53, the support bases 54, 55, and 56, the plurality of disc members 57, the driving mechanism 58, and the yarn guides 61, 62, and 63. The five rotating shafts 53 (common rotating shaft 71, first individual rotating shafts 72, 73, and second individual rotating shafts 74, 75) are shaft members extending in an axial direction substantially orthogonal to the longitudinal direction of the body. In addition, the axial direction does not need to be substantially orthogonal to the longitudinal direction of the body. Among the five rotating shafts 53 , a common rotating shaft 71 is arranged at the center in the longitudinal direction of the body, and two first individual rotating shafts 72 and 73 are arranged on one side of the common rotating shaft 71 in the longitudinal direction of the body. 1st false twist part 51. The common rotating shaft 71 and the two second individual rotating shafts 74 and 75 arranged on the other side of the common rotating shaft 71 in the longitudinal direction of the body are included in the second false twisting part 52 . In other words, the common rotation shaft 71 is shared by the first false twisting unit 51 and the second false twisting unit 52 . As shown in FIGS. 6(a) and 7(a) , the rotation axis 53 is arranged such that the center of the axis forms two virtual equilateral triangles (the first triangle 201 and the second triangle 202 ) when viewed from the axial direction. vertex. The common rotation axis 71 and the first individual rotation axes 72 and 73 form the vertex of the first triangle 201 . The common rotation axis 71 and the second individual rotation axes 74 and 75 form the vertex of the second triangle 202 . The first individual rotation shafts 72 and 73 and the second individual rotation shafts 74 and 75 are arranged on opposite sides to each other across the common rotation shaft 71 in the longitudinal direction of the body.

The support stands 54, 55, and 56 are stands that rotatably support the rotating shaft 53 via bearings (not shown). The support base 54 includes a common rotation shaft 71 , a first individual rotation shaft 72 of the first individual rotation shafts 72 , 73 arranged on the back side, and a second individual rotation shaft 74 , 75 of the second individual rotation shafts 74 , 75 arranged on the back side. The rotation shaft 74 is cantilevered and supported. The support base 55 is installed on the support base 54 and is arranged on the near side of the support base 54 , with the first individual rotation axis on the near side 73 is rotatably cantilevered. The support base 56 is attached to the support base 54 and is arranged on the near side of the support base 54 , and the second individual rotation shaft 75 on the near side is rotatably cantilever-supported. The upper side of the paper in FIGS. 4 and 5 is the distal end side in the axial direction, and the lower side of the paper is the proximal end side in the axial direction. The yarn Y travels from the distal end side to the base end side in the axial direction of the rotation shaft 53 . That is, the distal end side in the axial direction is the upstream side in the yarn traveling direction. The base end side in the axial direction is the downstream side in the yarn traveling direction. In addition, the traveling direction of the yarn Y1 is defined as the first yarn traveling direction, and the traveling direction of the yarn Y2 is defined as the second yarn traveling direction (see FIG. 5 ). In addition, the base end side portions of the support stands 54, 55, and 56 in the axial direction are respectively covers 54a, 55a, and 56a that cover a part of the drive mechanism 58 (see FIGS. 4 and 5).

The plurality of disc members 57 are attached to each rotation shaft 53 and are members that impart twist to the yarn Y by contacting the yarn Y. In addition, in this embodiment, in order to simplify the description, it is described that the disk members 57 are attached to all the rotation shafts 53 of all the five-axis false twisting devices 15 . In addition, in the present embodiment, three or four disc members 57 are attached to each rotation shaft 53 (see FIG. 4 etc.), but the number of disc members 57 attached to each rotation shaft 53 is not limited to this. .

First, among the plurality of disk members 57 , the plurality of disk members 57 attached to the common rotation shaft 71 and the first individual rotation shafts 72 and 73 are included in the first false twist portion 51 and extend in the axial direction as shown in the drawing. configured in a spiral fashion. The direction of the spiral drawn by the disc member 57 is determined by the direction of the twist performed on the yarn Y. That is, the five-axis false twisting device 15 (five-axis false twisting device 15a) that performs Z-twisting on the yarn Y is viewed from the distal end side in the axial direction. Refer to FIG. 6(a), (b)), the disc member 57 of the first false twist portion 51 is arranged to draw a spiral counterclockwise. On the other hand, when the five-axis false twisting device 15 (five-axis false twisting device 15b. See FIGS. 7(a) and (b)) that performs S-twisting on the yarn Y is viewed from the distal end side in the axial direction, the first The disc member 57 of the false twist portion 51 is arranged to draw a spiral clockwise.

In addition, the disc member 57 attached to the common rotation shaft 71 and the second individual rotation shafts 74 and 75 is included in the second false twist portion 52 and is arranged to draw a spiral extending in the axial direction. The direction of the spiral drawn by the disc member 57 included in the second false twist portion 52 is the same as the direction of the spiral drawn by the disc member 57 included in the first false twist portion 51 .

As shown in FIG. 5 , the disc member 57 (disc member 81 ) of the first false twisting portion 51 is disposed on the most upstream side in the first yarn traveling direction, and the second false twisting portion 52 is disposed on the second yarn. The disc member 57 (disc member 82) on the most upstream side in the line traveling direction is arranged in the same first plane 203 orthogonal to the axial direction. In other words, the axial position of the disk member 81 and the axial position of the disk member 82 are substantially the same. In addition, the disc member 57 (disc member 83) of the first false twisting portion 51 is arranged on the most downstream side in the first yarn traveling direction, and the second false twisting portion 52 is arranged on the second yarn traveling direction. The disc member 57 (disc member 84) on the most downstream side is arranged in the same second plane 204 orthogonal to the axial direction. In other words, the axial position of the disk member 83 and the axial position of the disk member 84 are substantially the same. This can prevent the rotation shaft 53 from becoming long, compared with a case where the axial positions of the disk members 81 and 82 are different from each other or the axial positions of the disk members 83 and 84 are different from each other.

In addition, the disc member 57 of the first false twist part 51 and the disc member 57 of the second false twist part 52 are arranged point symmetrically with each other with the common rotation axis 71 as the center of symmetry when viewed from the axial direction. As a specific example, in the five-axis false twisting device 15a (see (a) and (b) of FIG. 6 ), the disk member 81 of the first false twisting part 51 is attached to the first individual rotation shaft 73 on the near side, The disk member 82 of the second false twist part 52 is attached to the second individual rotation shaft 74 on the back side.

The contact portions of the plurality of disc members 57 and the yarn Y are formed of, for example, polyurethane. In this embodiment, at least one disc member 57 whose contact portion with the yarn Y is made of polyurethane is attached to each rotation shaft 53 . However, it is known that the disc member 57 (disc members 81 and 82) first contacted by the traveling yarn Y and the disc member 57 (disc members 83 and 84) contacted last are generally known to be easily worn. Therefore, the contact portions of the disc members 81, 82, 83, and 84 with the yarn Y are formed of, for example, ceramic, which is a member with higher wear resistance than polyurethane. This suppresses wear of the disk members 81, 82, 83, and 84. However, the present invention is not limited to this, and all portions of the disc member 57 that come into contact with the yarn Y may be formed of polyurethane.

The drive mechanism 58 is a mechanism that drives the five rotation shafts 53 to rotate in the same direction. The drive mechanism 58 includes a motor 85 (see FIG. 4 , a drive source and a common drive source of the present invention), and belts 86 , 87 , 88 , 89 (see FIG. 5 ) for transmitting the power of the motor 85 to each rotation shaft. The drive mechanism 58 of the five-axis false twisting device 15 (five-axis false twisting device 15a) that applies Z-twist to the yarn Y rotates the rotating shaft 53 counterclockwise when viewed from the distal end side in the axial direction (see ( in FIG. 6 arrows of a), (b)). The driving mechanism 58 of the five-axis false twisting device 15 (the five-axis false twisting device 15b) that applies an S-twist to the yarn Y is in the axial direction. The rotating shaft 53 is driven to rotate clockwise when viewed from the end side (see the arrows in (a) and (b) of FIG. 7 ). The drive mechanism 58 will be described in more detail later.

As shown in FIG. 5 , two yarn guides 61 , 62 , and 63 are provided corresponding to the first false twisting portion 51 and the second false twisting portion 52 . First, the yarn guide 61 (yarn guide 61a; the first yarn guide of the present invention) of the first false twist portion 51 is disposed close to the upstream side of the disc member 81 in the first yarn traveling direction. The yarn guide 62 (yarn guide 62a) of the first false twist portion 51 is disposed close to the disc member 83 on the downstream side in the first yarn traveling direction. The yarn guide 63 (yarn guide 63a) of the first false twist part 51 is disposed close to the downstream side of the yarn guide 62a in the first yarn traveling direction, and is fixed to one side of the support base 55 in the longitudinal direction of the body. Side end. In addition, the yarn guide 61 (yarn guide 61b; second yarn guide of the present invention) of the second false twist portion 52 is disposed close to the upstream side of the disk member 82 in the second yarn traveling direction. The yarn guide 62 (yarn guide 62b) of the second false twist portion 52 is disposed closely to the downstream side of the disk member 84 in the second yarn traveling direction. The yarn guide 63 (yarn guide 63b) of the second false twist part 52 is disposed close to the downstream side of the yarn guide 62b in the second yarn traveling direction, and is fixed to the other side of the support base 56 in the longitudinal direction of the body. One side end.

In the five-axis false twisting device 15 having the above configuration, the yarn Y is arranged to draw the following path (yarn path). As shown in FIG. 5 , first, the yarn Y1 is arranged to draw a spiral while contacting the plurality of disc members 57 of the first false twist portion 51 via the yarn guide 61 a. The yarn Y1 in contact with the disc member 57 is arranged to fall inside the first triangle 201 when viewed from the axial direction (see FIG. 6( a )) and travel inside the first triangle 201 . Furthermore, the yarn Y1 passes through the yarn guides 62a and 63a to the downstream in the first yarn traveling direction. Travel sideways. In addition, the yarn Y2 is arranged to draw a spiral while contacting the plurality of disk members 57 of the second false twist portion 52 via the yarn guide 61b. The yarn Y2 in contact with the disc member 57 is arranged to fall inside the second triangle 202 when viewed from the axial direction (see FIG. 6( a )) and travel inside the second triangle 202 . Furthermore, the yarn Y2 travels toward the downstream side in the second yarn traveling direction via the yarn guides 62b and 63b.

While the yarn Y is traveling in this way, the five rotation shafts 53 are rotationally driven in the same direction by the drive mechanism 58, thereby imparting twist to the yarn Y that is in contact with the rotating disk member 57. Specifically, in the five-axis false twisting device 15a for Z twisting (see (a) and (b) of FIG. 6 ), Z twist is given to both the yarn Y1 and the yarn Y2. In the five-axis false twisting device 15b for S twist (see (a) and (b) of FIG. 7 ), S twist is given to both the yarn Y1 and the yarn Y2.

However, in the above-mentioned five-axis false twisting device 15, the yarn needs to be hung in the first false twisting part 51 and the second false twisting part 52. Specifically, it is necessary to put the yarn Y1 into the inside of the first triangle 201 from between the two predetermined rotation shafts 53 and then hook the yarn Y1 to the yarn guides 61, 62, and 63. In addition, it is necessary to put the yarn Y2 into the inside of the second triangle 202 from between the two predetermined rotation shafts 53, and then hook the yarn Y2 to the yarn guides 61, 62, and 63. Yarn hanging is performed by an operator located in the work space 22 (see FIG. 1 ). Assume that as shown in the reference diagram of FIG. 8(a) , one of the first false twisting part 51 and the second false twisting part 52 is disposed further back than the other (the side farther from the work space 22 ), The yarn hooking operation in the false twisting portion (the second false twisting portion 52 in Fig. 8(a) ) on the inner side becomes extremely difficult. Therefore, it is necessary to orient both the first false twisting part 51 and the second false twisting part 52 In the form of the working space 22, the first false twisting part 51 and the second false twisting part 52 are arranged side by side in the longitudinal direction of the machine body (see the reference diagram of Fig. 8(b)).

In addition, as described above, the disc member 57 of the first false twist portion 51 and the disc member 57 of the second false twist portion 52 are arranged point-symmetrically with each other when viewed from the axial direction. In this structure, three methods can be considered for hanging the yarn on the disc member 57 as shown in FIG. 8(b) . The first method, as shown in the left part of the paper in Figure 8(b), is a method of hanging the yarn from the near side to the first false twisting part 51 and the yarn from the back side to the second false twisting part 52 (refer to Figure 8 Arrows 205, 206 of (b)). The second method, as shown in the center part of the paper in Fig. 8(b) , is a method of hanging yarn on the first false twisting part 51 from the back side and hanging yarn on the second false twisting part 52 from the near side (refer to Fig. 8 Arrows 207, 208 of (b)). The third method, as shown on the right side of the paper in Figure 8(b), is to hang the yarn from one side in the longitudinal direction of the machine body to the first false twisting part 51, and from the other side in the longitudinal direction of the machine body to the second false twisting part. This is a method of hanging the yarn on the twisted portion 52 (see arrows 209 and 210 in Fig. 8(b) ). In addition, in order to find another yarn hanging method, it is also considered to arrange the disc member 57 of the first false twist part 51 and the disc member 57 of the second false twist part 52 so that they are not point symmetrical with each other. However, in reality, it is difficult to adopt such a configuration for the following reasons. That is, when the disc member 57 of the first false twist part 51 and the disc member 57 of the second false twist part 52 are not point symmetrical with each other, the axial direction of the disc member 57 of the first false twist part 51 The position is offset from the position in the axial direction of the disc member 57 of the second false twist portion 52 . In this case, the yarn path of the yarn Y1 is significantly different from the yarn path of the yarn Y2, which may cause uneven yarn quality. In addition, since the rotating shaft 53 becomes longer, there is also a problem that the apparatus will be enlarged. problem. For these reasons, it is actually required that the disc member 57 of the first false twist portion 51 The disc member 57 of the second false twist portion 52 is arranged point-symmetrically with each other.

On this basis, the first and second methods among the above three methods are difficult to adopt because it is difficult to hang yarn from the inside. Therefore, the five-axis false twisting device 15 is required to be able to apply the third method. More specifically, in the five-axis false twisting device 15 in this embodiment, the yarn Y1 is hung from between the two first individual rotating shafts 72 and 73, and the yarn Y2 is hung from the two second individual rotating shafts 74 and 73. Hang yarn between 75 and 75. However, in this configuration, when yarn is hung on a certain five-axis false twisting device 15, there is a narrowing of the working space between another five-axis false twisting device 15 arranged adjacently in the longitudinal direction of the body. (Refer to Fig. 8(b)), there is a concern that the yarn hanging operation will become difficult. Therefore, in this embodiment, in order to facilitate the yarn hanging operation, the five-axis false twisting device 15 has the following configuration.

(Detailed structure of five-axis false twisting device)

The detailed structure of the five-axis false twisting device 15 will be described with reference to FIGS. 9(a) and (b). FIG. 9(a) is an explanatory diagram showing the five-axis false twisting device 15 when the first individual rotating shaft 73 is located at a first operating position (described later) and the second individual rotating shaft 75 is located at a second operating position (described later). Fig. 9(b) is an explanatory diagram showing the five-axis false twisting device 15 when the first individual rotating shaft 73 is located at a first yarn hanging position (to be described later) and the second individual rotating shaft 75 is located at a second yarn hanging position (to be described later).

Among the first individual rotation shafts 72 and 73 , the first individual rotation shaft 73 (one of the first movable shafts in the present invention and the first movable shaft) arranged on the near side is rotatably supported on the support base 55 so as to share the axis center of the rotation shaft 71 The center of the swing axis is swingably mounted on the support platform 54 . In other words, the support platform 54 and the support platform 55 For example, it can be opened and closed like a hinge. Thereby, the first individual rotating shaft 73 can be in the operating position (the first operating position. See FIG. 9(a) ) when the five-axis false twisting device 15 is operating (when twisting is imparted to the yarn Y) and as compared to the first operating position. The action position moves between the yarn hanging position (the first yarn hanging position. See Figure 9(b)) closer to the side of the body. Therefore, when hanging the yarn, the gap between the two first individual rotating shafts 72 and 73 can be increased. Therefore, even in a configuration in which a plurality of five-axis false twisting devices 15 are arranged in the longitudinal direction of the machine body, it is easy to hang the yarn Y1 from the work space 22 (see arrow 211 in FIG. 9(b) ). More specifically, when viewed from the axial direction, the first individual rotation shaft 73 can change the distance from the first individual rotation shaft 72 while maintaining the distance from the common rotation shaft 71 constant. Similarly, among the second individual rotation shafts 74 and 75 , the second individual rotation shaft 75 (one of the first and second movable shafts of the present invention) arranged on the near side is supported rotatably on the support base 56 so that the rotation shaft 71 is shared. The axis center is the swing axis center and is swingably mounted on the support platform 54 . Thereby, the second individual rotating shaft 75 can be in the operating position when the five-axis false twisting device 15 is operating (the second operating position; see FIG. 9(a) ) and as a yarn hanging position closer to the body than the second operating position. (The second yarn hanging position. Refer to Figure 9(b)). This allows the gap between the two second individual rotating shafts 74 and 75 to be increased during yarn hanging. Therefore, even in a configuration in which a plurality of five-axis false twisting devices 15 are arranged in the longitudinal direction of the machine body, it is easy to hang the yarn Y2 from the working space 22 (see arrow 212 in FIG. 9(b) ). In this way, the yarn hooking operation to the five-axis false twisting device 15 can be easily performed. In addition, the support stands 54, 55, and 56 may all rotatably support the common rotation shaft 71 via bearings (not shown).

Furthermore, when the first individual rotating shaft 73 and the second individual rotating shaft 73 are rotated When the rotating shafts 75 move from the operating position to the yarn hanging position, their rotating shafts 53 move toward the body side and inward of the five-axis false twisting device 15 in the longitudinal direction of the body (the common rotating shaft 71 side). Therefore, during the yarn hanging operation, interference between the five-axis false twisting devices 15 adjacent to each other in the longitudinal direction of the machine body can be avoided. In other words, there is no need to widen the intervals between the plurality of five-axis false twisting devices 15 in order to make the first individual rotation shaft 73 and the second individual rotation shaft 75 movable. Therefore, it is possible to suppress the increase in the size of the body of the false twisting machine 1 in the longitudinal direction and to facilitate the yarn hanging operation.

In addition, as described above, the yarn guide 63a is fixed to the support base 55, and the yarn guide 63b is fixed to the support base 56. Therefore, when the first individual rotating shaft 73 moves from the first operating position to the first yarn hanging position, the yarn guide 63a is also moved toward the near side and is inward (common) of the five-axis false twisting device 15 in the longitudinal direction of the body. The rotation shaft 71 side) moves (refer to Fig. 9(b)). In addition, when the second individual rotating shaft 75 moves from the second operating position to the second yarn hanging position, the yarn guide 63b is also moved toward the near side and is the inside of the five-axis false twisting device 15 in the longitudinal direction of the body (shared). The rotation shaft 71 side) moves (refer to Fig. 9(b)). By moving the yarn guides 63a and 63b (the yarn guide 63) toward the body side (the side closer to the operator), the yarn hanging operation on the yarn guide 63 can be easily performed. In addition, by moving the yarn guide 63 toward the inner side (towards the common rotation axis 71 ) of the five-axis false twisting device 15 in the longitudinal direction of the body, the distance between the yarn guide 63 and the yarn guide 63 of the adjacent five-axis false twisting device 15 is increased. widen. Therefore, the yarn hanging operation on the yarn guide 63 becomes easier.

Here, the rotation angle of the support base 55 when moving the first individual rotating shaft 73 from the first operating position to the first yarn hanging position is preferably, for example, 27 degrees or more and 30 degrees or less. By the above rotation angle being 27 degrees or more, the When the first individual rotating shaft 73 is located at the first yarn hanging position, the disc member 57 installed on the first individual rotating shaft 72 and the disc member 57 installed on the first individual rotating shaft 73 are substantially different when viewed from the axial direction. overlap (refer to Figure 9(b)). Therefore, it is easy to put the yarn Y1 into the inside of the first triangle 201 from between the first individual rotating shaft 72 and the first individual rotating shaft 73 and to hang the yarn on the yarn guides 61, 62, and 63. In addition, since the above-mentioned rotation angle is 30 degrees or less, it is possible to prevent the support base 55 and the support base 56 from interfering with each other and causing unexpected movement, etc., thereby preventing the yarn hanging operation from being hindered. The same applies to the rotation angle of the support base 56 when moving the second individual rotating shaft 75 from the second operating position to the second yarn hanging position.

In addition, the common rotation shaft 71, the first individual rotation shaft 72, and the second individual rotation shaft 74 are rotatably attached to the support base 54, and their positions are fixed. That is, among the five rotating shafts 53 , excluding the first individual rotating shaft 73 and the second individual rotating shaft 75 , the common rotating shaft 71 , the first individual rotating shaft 72 , and the second individual rotating shaft 74 correspond to three fixed rotating shafts in the present invention. axis of rotation.

Next, other structures of the five-axis false twisting device 15 will be described in detail with reference to Figs. 10(a) to (c), Fig. 11 and others. FIG. 10( a ) is a view of the guide support portion 90 (described later) viewed from the distal end side in the axial direction. Fig. 10(b) is an explanatory diagram showing the yarn path when viewed from the longitudinal direction of the machine body before position adjustment of the yarn guides 61a and 61b. Fig. 10(c) is an explanatory diagram showing the yarn path when viewed from the longitudinal direction of the machine body after the positions of the yarn guides 61a and 61b are adjusted. FIG. 11 is a view of the drive mechanism as viewed from the base end side in the axial direction.

(Construction of the periphery of the yarn guide)

The structure around the yarn guides 61a and 61b will be described. As shown in Fig. 4 and Fig. 10(a) , the five-axis false twisting device 15 has a guide support portion 90 that supports the yarn guides 61a and 61b arranged on the upstream side in the yarn traveling direction. The guide support part 90 has, for example, a first support member 91 and a second support member 92 . The first support member 91 is a member attached to the back end of the support base 54 and one end in the longitudinal direction of the body, and extends in the axial direction. The second support member 92 is a member attached to the axial front end portion of the first support member 91 . The second member has an extension portion 93 extending inward of the five-axis false twisting device 15 in the longitudinal direction of the body, and is provided integrally with the extension portion 93 in a direction substantially perpendicular to both the axial direction and the longitudinal direction of the body. A pair of extended guide mounting portions 94a, 94b. The guide mounting portion 94a is arranged on one side (the first false twisting portion 51 side) of the five-axis false twisting device 15 in the longitudinal direction of the body. The guide mounting portion 94b is disposed on the other side (the second false twisting portion 52 side) of the five-axis false twisting device 15 in the longitudinal direction of the body.

As shown in FIG. 4 , the guide mounting portion 94a is formed with a mounting hole 95a for mounting the yarn guide 61a, and the guide mounting portion 94b is formed with a mounting hole 95b for mounting the yarn guide 61b. In addition, as shown in FIG. 10(a) , the yarn guide 61a is attached to the guide mounting portion 94a using a fixing tool 96a having a screw (not shown) passing through the mounting hole 95a. Similarly, the yarn guide 61b is attached to the guide attachment part 94b using the fixing tool 96b. In addition, the mounting holes 95a and 95b extend in directions substantially perpendicular to both the axial direction and the body longitudinal direction (see FIG. 4 ). Therefore, when viewed from the axial direction, the yarn guides 61a and 61b are movable yarn guides whose position can be adjusted in a direction substantially perpendicular to the longitudinal direction of the body. Specifically, by loosening the fixing device 96a, the yarn guide can be The member 61a moves along the mounting hole 95a. Furthermore, the position of the yarn guide 61a can be fixed by tightening the fixing tool 96a. The same applies to the yarn guide 61b.

Here, as described above, the disc member 81 of the first false twist part 51 and the disc member 82 of the second false twist part 52 are arranged in point symmetry with each other (see FIG. 6(a) ). That is, when viewed from the longitudinal direction of the body, the positions of the disc member 81 and the disc member 82 are different from each other. Therefore, as shown in FIG. 10(b) , it is assumed that when the yarn guides 61a and 61b overlap each other when viewed from the longitudinal direction of the body, the bending angle of the yarn Y1 traveling through the yarn guide 61a and the angle of the yarn Y1 passing through the guide The bending angles of the yarns Y2 traveling through the yarn members 62 are different from each other. In this case, there is a concern that the yarn quality of the yarn Y1 and the yarn Y2 are not uniform. Regarding this point, in this embodiment, since the yarn guides 61a and 61b are movable yarn guides, the relative positional relationship between the yarn guide 61a and the yarn guide 61b can be adjusted. Therefore, by appropriately adjusting the positions of the yarn guides 61a and 61b, the difference between the bending angle of the yarn Y1 and the bending angle of the yarn Y2 can be reduced (see FIG. 10(c) ).

(Details of drive mechanism)

Next, the details of the drive mechanism 58 will be described. As shown in FIG. 11 , the drive mechanism 58 has a motor 85 and belts 86 , 87 , 88 , and 89 . The motor 85 is a drive source that is arranged on the inner side of the support base 54 and drives the five rotation axes together. The belt 86 is an endless belt for transmitting the power of the motor 85 to the common rotation shaft 71 (intermediate shaft of the present invention). The belt 86 is wound around the pulley 101 attached to the drive shaft 85 a of the motor 85 and the pulley 102 attached to the common rotation shaft 71 .

The belt 87 (common belt in the present invention) is an endless belt used to transmit the power of the motor 85 to the remaining two of the three fixed rotation shafts, namely the first individual rotation shaft 72 and the second individual rotation shaft 74 , via the common rotation shaft 71 . The belt 87 is wound around the pulley 103 attached to the common rotating shaft 71 , the pulley 104 attached to the first individual rotating shaft 72 , and the pulley 105 attached to the second individual rotating shaft 74 (see FIG. 5 and Figure 11).

The belt 88 is an endless belt for transmitting the power of the motor 85 to the first individual rotating shaft 73 via the common rotating shaft 71 . The belt 88 is wound around the pulley 106 attached to the common rotating shaft 71 and the pulley 107 attached to the first individual rotating shaft 73 (see FIGS. 5 and 11 ). The belt 89 is an endless belt for transmitting the power of the motor 85 to the second individual rotating shaft 75 via the common rotating shaft 71 . The belt 89 is wound around the pulley 108 attached to the common rotating shaft 71 and the pulley 109 attached to the second individual rotating shaft 75 (see FIGS. 5 and 11 ).

Here, it is assumed that instead of the belt 87 for jointly driving the first individual rotating shaft 72 and the second individual rotating shaft 74 , belts for transmitting power to the first individual rotating shaft 72 and belts for transmitting power to the second individual rotating shaft 74 are respectively provided. In the construction of power belts, the number of belts increases. Therefore, the number of pulleys attached to the common rotating shaft 71 also increases, and a problem arises that the common rotating shaft 71 has to be made longer. In this regard, in this embodiment, since the three fixed rotation shafts can be collectively driven by the belts 87, the number of belts can be kept small.

As described above, the first individual rotating shaft 73 can be positioned between the first operating position and the first yarn hanging position closer to the body than the first operating position. Move. This allows the gap between the two first individual rotating shafts 72 and 73 to be increased when the yarn is hung on the first false twisting portion 51 . Therefore, even in a configuration in which a plurality of five-axis false twisting devices 15 are arranged in a row along the longitudinal direction of the machine body, yarn can be easily hung from the work space 22 . Similarly, the second individual rotating shaft 75 can also move between the second operating position and the second yarn hanging position. Therefore, when the yarn is hung on the second false twisting section 52, the two second individual rotating shafts 74 and 74 can be enlarged. The gap between 75. As described above, in the false twisting machine 1 in which the five-axis false twisting devices 15 are arranged in the longitudinal direction of the machine body, the yarn hanging operation can be easily performed.

In addition, the first individual rotation shaft 73 and the second individual rotation shaft 75 can swing about the common rotation shaft 71 as the swing axis center. That is, when the first individual rotary shaft 73 and the second individual rotary shaft 75 are moved, the distance between the first individual rotary shaft 73 and the common rotary shaft 71 and the distance between the second individual rotary shaft 75 and the common rotary shaft 71 do not change. . Therefore, it is possible to prevent the belts 88 and 89 from becoming loose or being damaged due to excessive tension.

In addition, by adjusting the positions of the yarn guides 61a and 61b, the difference in the yarn path of the yarn Y1 guided by the yarn guide 61a and the yarn path of the yarn Y2 guided by the yarn guide 61b can be suppressed to a small value. Therefore, unevenness in yarn quality between the yarn Y1 and the yarn Y2 can be suppressed.

In addition, the yarn guides 61a and 61b are movable in a direction substantially orthogonal to the longitudinal direction of the body when viewed from the axial direction. Therefore, interference between the yarn guides 61a and 61b can be suppressed and the movable range of the yarn guides 61a and 61b can be widened, so that the yarn path can be effectively adjusted.

In addition, since the belt 87 can be used to centrally drive the common rotary Since the rotation shaft 71, the first individual rotation shaft 72, and the second individual rotation shaft 74 are provided, the number of belts can be kept small. Therefore, it is possible to suppress the elongation of the rotating shaft 53 and to suppress the device from being enlarged.

In addition, the power of the motor 85 is transmitted to the common rotation shaft 71 arranged at the center in the longitudinal direction of the body among the five rotation shafts 53 . Therefore, the five-axis false twisting device 15 can further transmit power to the other rotation shafts 53 arranged around the common rotation shaft 71 . Therefore, the structure for power transmission can be simplified.

In addition, the disc member 81 on the most upstream side in the first yarn traveling direction of the first false twist section 51 and the disc member 82 on the most upstream side in the second yarn traveling direction of the second false twist section 52 are arranged. in the same first plane 203. Furthermore, the disc member 83 on the most downstream side in the first yarn traveling direction of the first false twist section 51 and the disc member 84 on the most downstream side in the second yarn traveling direction of the second false twist section 52 are arranged. in the same second plane 204. Thereby, the arrangement structure of the disc member 57 in the axial direction can be made compact. Therefore, it is possible to suppress an increase in the size of the device in the axial direction.

Next, a modification example in which changes are made to the above-described embodiment will be described. However, components having the same components as those in the above-mentioned embodiment are denoted by the same reference numerals, and description thereof is appropriately omitted.

(1) In the above embodiment, in the false twisting machine 1 , the disc members 57 are attached to all the rotation axes 53 of all the five-axis false twisting devices 15 , but the invention is not limited to this. For example, for the purpose of cost reduction, the rotating shaft 53 that is never used for yarn processing (for example, the rotating shaft 53 that is part of the five-axis false twisting device 15 arranged on the leftmost side of the paper in FIG. 2 ) may be removed. Remove unnecessary disc members 57 . However, in the configuration in which the five rotating shafts 53 are driven together by the motor 85 described above, the following problems may occur. That is, by simply removing the disk member 57 from a part of the rotation shaft 53 in a certain five-axis false twisting device 15, the load applied to the motor 85 of the five-axis false twisting device 15 is the same as that applied to the other five-axis false twisting device 15. The load applied to the motor 85 of the twisting device 15 becomes smaller in comparison. Then, in the five-axis false twisting device 15 from which part of the disk member 57 was removed, the five rotation shafts 53 unexpectedly rotated rapidly. As a result, there is a concern that the yarn quality of the yarn processed by the five-axis false twisting device 15 is greatly different from the yarn quality of the yarn processed by the other five-axis false twisting device 15 . Therefore, as shown in (a) and (b) of FIG. 12 , in the five-axis false twisting device 15 in which a part of the disc member 57 is removed, a disc member 57 may be provided instead of the removed disc member 57 . Counterweight. For example, as shown in FIG. 12(a) , a counterweight 110 may be provided in place of the disc member 57 in the five-axis false twisting device 15 c in which the disc member 57 is removed from the first individual rotation shafts 72 and 73 . Similarly, as shown in FIG. 12(b) , a counterweight 110 may be provided in place of the disc member 57 in the five-axis false twisting device 15d in which the disc member 57 is removed from the second individual rotation shafts 74 and 75. This makes it possible to prevent the rotation shaft 53 from unexpectedly rapid rotation because these counterweights 110 serve as loads. Therefore, by using a member that is cheaper than the disc member 57 as the counterweight 110, it is possible to suppress an increase in cost and suppress variation in yarn quality between the five-axis false twisting devices 15.

Alternatively, instead of providing the counterweight 110 , the five-axis false twisting device 15 with a portion of the disc member 57 removed may perform feedback control on the rotational speed of the motor 85 . For example, the five-axis false twisting device 15 may also have a not-shown device for controlling the rotation speed of the motor 85 that drives the five rotating shafts 53 together. inverter device. Alternatively, as another means, the five-axis false twisting device 15 from which part of the disc member 57 is removed may have five motors (not shown) that independently rotate and drive each rotation axis 53 .

(2) In the embodiment described so far, the disc member 57 whose contact portion with the yarn Y is made of polyurethane is attached to all the rotation shafts 53 , but it is not limited to this. That is, the disc members 57 provided on the common rotation shaft 71 are in principle contact with both the yarn Y1 and the yarn Y2. Therefore, these disc members 57 may wear earlier than the disc members 57 provided on the other rotation shafts 53. . Therefore, for example, the portions in contact with the yarn Y of all the disk members 57 attached to the common rotation shaft 71 may be formed of ceramics having higher wear resistance than polyurethane. That is, the wear resistance of the portion of the disk member 57 attached to the common rotation shaft 71 that comes into contact with the yarn Y may be higher than that of the disk member 57 attached to the rotation shaft 53 other than the common rotation shaft 71 and the yarn Y. The contact portion of the line Y has high wear resistance. This can prevent premature wear of only the disk member 57 provided on the common rotation shaft 71 . Therefore, it is possible to avoid the necessity of early replacement of only a part of the disk member 57 . In addition, the material of the portion in contact with the yarn Y of the disc member 57 is not limited to the above-mentioned polyurethane or ceramic.

(3) In the embodiment described so far, the disc member 81 of the first false twist part 51 and the disc member 82 of the second false twist part 52 are arranged in the same first plane 203. However, this is not limited to this. The disc member 81 and the disc member 82 do not need to be arranged on the same plane. Similarly, the disc member 83 of the first false twist part 51 and the disc member 84 of the second false twist part 52 do not need to be arranged in the same second plane 204.

(4) In the embodiment described so far, the belt 86 transmits power from the motor 85 to the common rotation shaft 71 (that is, the common rotation shaft 71 corresponds to the intermediate shaft of the present invention), but is not limited to this. For example, the five-axis false twisting device 15 may use the belt 86 to transmit power from the motor 85 to the first individual rotating shaft 72 or from the motor 85 to the second individual rotating shaft 74 .

(5) In the embodiment described so far, the belt 87 transmits power to both the first individual rotation shaft 72 and the second individual rotation shaft 74 via the common rotation shaft 71 , but the invention is not limited to this. That is, the power transmitted to the common rotating shaft 71 may be transmitted to the first individual rotating shaft 72 and the second individual rotating shaft 74 via different belts.

(6) In the embodiment described so far, the rotating shaft 53 is driven by a belt, but it is not limited to this. For example, a gear or a chain may be provided instead of a belt as a transmission member for transmitting the power of the drive source to each rotation shaft 53 .

(7) In the embodiment described so far, the yarn guides 61a and 61b are movable in the direction substantially orthogonal to the longitudinal direction of the body when viewed from the axial direction, but the invention is not limited thereto. The movable direction of the yarn guides 61a and 61b may be inclined from a direction substantially orthogonal to the longitudinal direction of the body. In other words, the yarn guides 61a and 61b may be movable in a direction crossing the longitudinal direction of the body.

(8) In the embodiment described so far, the positions of both yarn guides 61a and 61b can be adjusted, but the invention is not limited to this. That is, only one of the yarn guides 61a and 61b may be position-adjustable relative to the other. In other words, at least one of the yarn guides 61a and 61b may be position-adjustable relative to the other.

(9) In the modification of the above (8), at least one of the yarn guides 61a and 61b may be position-adjustable relative to the other, but it is not limited to this. The position of the yarn guide 61a and the yarn guide 61b may not necessarily be adjustable.

(10) In the embodiment described so far, the first individual rotation shaft 73 and the second individual rotation shaft 75 can swing about the common rotation shaft 71 as the swing axis, but they are not limited to this. For example, the first individual rotation shaft 73 and the second individual rotation shaft 75 may be linearly movable.

(11) In the embodiment described so far, the false twisting machine 1 is provided with the doubling device 17 , but the false twisting machine 1 does not necessarily need to be equipped with the doubling device 17 .

(12) In the embodiment described so far, the winding device 21 can be configured in the first mode in which the yarn Y is wound around one winding bobbin Bw and in the first mode in which the yarn Y is wound around two winding bobbins Bw. The operation mode is switched between the second mode, but it is not limited to this. For example, the winding device 21 may be able to select an operation mode for winding the yarn Y to three or more winding bobbins Bw. Alternatively, the winding device 21 may wind the yarn Y onto only one winding bobbin Bw.

(13) In the embodiment described so far, the false twisting machine 1 performs false twisting on the yarn Y made of nylon, but the invention is not limited to this. The false twisting machine 1 may perform false twisting on a yarn made of polyester, for example.

(14) In a structure in which the support stands 54, 55, and 56 rotatably support the common rotation shaft 71 via bearings (not shown), for example, if the support stand 55 is swung, the support stand 56 may be unexpectedly moved from the position due to friction. Swinging concerns may arise as follows. For example, if the support base 56 unexpectedly swings toward the body side after the yarn hooking operation to the second false twisting unit 52 has been completed, the yarn Y2 may separate from the second false twisting unit 52 and need to be re-arranged. Carry out yarn hanging operation. Therefore, the five-axis false twisting device 15 may be provided with a locking mechanism for preventing the rotating shaft 53 from accidentally moving from the operating position to the yarn hanging position. All components of a locking mechanism can also be provided in a corresponding five-axis false twisting device 15 . Alternatively, as shown in (a) and (b) of FIG. 13 , the locking mechanism 120 may be provided across the support base 55 of a certain five-axis false twisting device 15 to the five-axis false twisting device 15 adjacent to the five-axis false twisting device 15 . The support platform 56 of the false twisting device 15. Specifically, as shown in FIG. 13(b) , the locking mechanism 120 has a vertically long plate member 121, a rotation shaft 122 provided on the side surface of the support base 56 of a certain five-axis false twisting device 15, and and the convex portion 123 provided on the side surface of the adjacent support base 55 of the five-axis false twisting device 15. One end of the plate member 121 in the extending direction is attached to the side surface on the near side of the support base 56 via the rotation shaft 122 . That is, the plate member 121 is rotatably attached to the support base 56 . For example, a U-shaped notch 121 a is formed at the other end in the extending direction of the plate member 121 . Thereby, the other end part of the plate member 121 becomes an engaging part engageable with the convex part 123. When the plate member 121 is engaged with the convex portion 123 (see the solid line in FIG. 13( b )), the support stands 55 and 56 provided with the locking mechanism 120 can be prevented from accidentally moving toward the body side. When the engagement between the plate member 121 and the convex portion 123 is released (see the two-dot chain line in FIG. 13( b )), the support stands 55 and 56 can be moved closer to the body. Alternatively, the yarn Y1 processed by a certain five-axis false twisting device 15 and the yarn processed by the five-axis false twisting device 15 adjacent to the five-axis false twisting device 15 may be used. In the case of Y2 yarn doubling, the above-mentioned locking mechanism 120 is also provided.
