Description

The first aspect of the present invention is a method of manufacturing a warp for a handle, in which different yarns are guided around a winding body and are fed onto a transport surface of a transport device that moves parallel to the rotation axis. Regarding a method of manufacturing warp for use,
The second aspect of the invention includes one winding body, at least one yarn guide that can move around the winding body, a conveyance surface of one conveyance device that can move in the axial direction parallel to the rotation axis, The present invention relates to a partial warp for a warp having a yarn control device and having at least one dividing rod.

  A method for producing a pattern warp and such a partial warp for a pattern warp are known from US Pat. In Patent Document 1, a plurality of yarns are always warped simultaneously. Here, depending on how many yarns are warped simultaneously, i.e. depending on the width of the "yarn band" formed by simultaneously warped yarns, The moving speed is changed. In this way, the surface of the yarn layer is prevented from being uneven or uneven on the transport surface of the transport device.

  Even in a method known from Patent Document 2, the speed of the transport surface of the transport device is changed. In the invention described in Patent Document 2, the transport surface of this transport device depends on parameters relating to another thread, for example, the thickness of the thread. The speed of is changed. In the case of a thick thread, the transport surface of the transport device is moved faster than in the case of a thin thread. The same is performed when a plurality of yarns are wound simultaneously.

  In the known invention, the change in the moving speed of the conveying surface of the conveying device formed by the conveyor belt achieves uniformization of each yarn layer formed by the yarn fed on the conveyor belt. A simple method is adopted.

However, such an approach has a series of drawbacks as follows. That is, a predetermined time for change is always required for changing the moving speed.
In addition, non-uniformity can occur well in the yarn layer of the yarn that is subsequently wound at two different speed transitions within this predetermined time. In particular, such a situation is likely to occur when a large amount of yarn is already wound around the winding body.
Furthermore, since the yarn has a constant weight, the total weight is sufficiently several tens of kg. Further, as the winding around the winding body increases, the tension applied from the yarn to the conveyor belt also increases. These tensions cause the aforementioned speed change to be further delayed.
In addition, the speed change generally does not become the “target speed” at one time.
Furthermore, a non-uniform state may occur in the yarn layer by the time when the speed is stabilized.
Also, the forces required to accelerate or brake the conveyor belt cause a certain amount of wear.

  A first problem of the present invention is to provide a method for producing (warping) a warp for a pattern having an improved configuration of each yarn layer, and a second problem is a pattern warp for carrying out the method. It is to provide a partial warping machine.

  The first problem is that in the manufacturing method (warping method) of the type pointed out at the beginning, the transport surface of the transport device moves at a constant speed, and the distance between the yarn supply point and the reference surface is This can be solved by making the selection dependent on at least one parameter affecting the size of the yarn band containing the yarn.

The change of the moving speed of the transfer surface of the transfer device and all the related problems can be solved at once.
According to such an invention, it is sufficient to move the transport surface of the transport device only once, and the speed only needs to be maintained constant. The change in the yarn supply state required due to the difference in the size of the yarn band is performed by controlling the yarn supply. Each yarn is fed in a specific region, and is generally performed at one end of the transport surface of the transport device. Therefore, the reference surface , for example, the end of the transport surface of the transport device can be used as a reference surface, and individual yarns can be fed at a predetermined distance from the reference surface .
When this distance is changed, it can be set to a desired distance by using different parameters.
As such a parameter, for example, the number of yarns different for each yarn band can be used as a parameter. When warping a plurality of yarns at the same time, for example, when winding seven yarns, a larger space is required than when winding two yarns, and in such a case, the number of yarns as a parameter is different. It will be.
In an extreme case, the yarn band may be a yarn band having only one yarn.

  Even in the case of a yarn band having only one yarn as described above, a difference may occur depending on whether, for example, a thick yarn or a thin yarn is used. A thick thread requires more space than a thin thread for the following two reasons. First, the thick yarn is wider than the thin yarn when viewed in the moving direction of the conveying surface of the conveying device. Secondly, the thick yarn is more bulky in the radial direction of the wound body.

  If you want to ensure a uniform surface of the yarn layer, prepare a little extra space next to the thick yarn in the moving direction of the conveying surface of the conveying device, and consider that this thick yarn can be pushed into this space during compression. There must be. As another method, a uniform surface of the yarn layer can be secured by feeding two winding layers side by side in the case of a thick yarn and by overlapping two winding layers in the case of a thin yarn. it can. All of this can be achieved by controlling (changing) the distance from the reference surface to which each yarn on the conveying surface of the conveying device feeds.

  The change of the distance can be realized much more easily than the change of the speed of the transfer surface of the transfer device. This is because instead of a large amount of yarn guided by a plurality of winding layers around the winding body, it is only necessary to move a much smaller mass, that is to say, always a single yarn. Correspondingly, the positioning of each yarn at the moment of yarn feeding can be done much more accurately than the positioning done by changing the speed, which in some cases is just the speed change region. It is also possible to do this within.

The second problem is that, in the type of warp partial warper of the type pointed out at the beginning, the yarn guide has one yarn feeding portion that can be changed in the axial direction, and the dividing rod is in the rotational axis direction (axial direction). This is solved by being configured to perform the method of manufacturing the pattern warp .

  As described above, when the yarn is fed, the winding surface is moved at a constant speed and the yarn guide is moved (moved in the axial direction) at a higher speed or lower speed than the conveying surface of the conveying device. The space of different sizes required on the body is obtained. In other words, the yarn guide is used to wind the yarn so that a relatively uniform yarn layer is produced regardless of the type of yarn band (large or small yarn band, thick yarn or thin yarn). It is possible to feed yarn onto the body. At that time, the surface of the yarn layer may not be completely flat. Small irregularities are well tolerated. However, these irregularities are small enough not to cause an undesirable change in tension when the yarn layer is later fed out. Naturally, the situation between the movement path of each yarn and the intervention position of the dividing rod also changes with the change of the portion to which the yarn is fed. In order to avoid the negative effect of this change, the dividing rod may be provided with mobility. That is, the dividing rod is moved forward or backward in the axial direction depending on where the yarn movement path is located. In this way, it is possible to always hold the dividing rod at a position where the dividing rod can grip each yarn with required reliability.

Regarding the invention of the warping method according to the present invention,
Preferably, the large distance selected at the time of feeding one yarn band is compensated by the small distance selected at the time of feeding the yarn band wound later, or selected at the time of feeding one yarn band. The smaller distance is compensated by the larger distance selected when feeding the subsequently wound yarn band. At the same time, the area that the yarn guide must cover can be kept small. Yarn bands with many yarns require a large space. Accordingly, when the yarn band is a yarn (yarn band) exceeding the average value, the distance from the reference point must be selected to be large in any case. A small yarn band, for example, a yarn band with a small number of yarns, requires less space. Such unnecessary space for the small yarn band is offset (compensated) with the large space required for the large yarn band. In the opposite case, it is canceled (compensated) in the same manner. The excessive schlagweite of the yarn guide, which is necessary for yarn feeding, is thus prevented.

  Further, a plurality of yarns are wound around the winding body at the same time, and a rotary creel is used for the winding, and the rotary creel is equipped with a yarn bobbin so that the change in the distance is minimized. And a preferred configuration. Here, the pattern to be obtained by warping, that is, the arrangement order of individual yarns is known. By the way, by properly equipped with a rotary creel, the yarn can be wound in the correct order, the influence of the difference between the yarn bands can be minimized, and the change in the distance can be minimized. Can do. This also makes it possible to keep the transition width of the yarn guide small.

  In this warping method, it is particularly preferable that individual yarns of one yarn band are fed onto the conveyance surface of the conveyance device by the yarn guide in the direction of movement of the conveyance surface of the conveyance device when the yarn guide rotates. It becomes. This configuration further improves the configuration (state) of each yarn layer. In particular, when winding is performed after warping, that is, when the yarn layer is cut with a twill and the yarn sheet thus formed is then pulled out, the number of intersections where the yarns rub against each other is reduced. Further, the yarn tension becomes more uniform. Parallel yarn feeding of the individual yarns can easily be achieved by correspondingly controlling the yarn guide.

  In this warping method, it is advantageous to use a rotating yarn guide in which the position of the thread guide hole is adjustable in the direction of movement of the conveying surface of the conveying device. Such a movable structure can be obtained by arranging a yarn guide at the end of the arm, which is arranged on the yarn guide lever so as to be rotatable at the end of the rotating yarn guide lever. In such a configuration, a desired change in the yarn feeding position can be obtained by adjusting the angle of the arm with respect to the yarn guide lever. With a correspondingly long arm, a relatively large change in the distance can be realized.

  In this warping method, it is preferable that a fluctuation margin is mainly planned in the range of +20 mm to −20 mm, particularly in the range of +10 mm to −10 mm. In other words, with a variation margin of at least +/− 10 mm, a yarn feed distance of up to 2 cm (20 mm) can be accepted before compensation must be started. At the same time, most of the pattern (arrangement) to be warped can be realized.

  In this warping method, it is preferable that a conical surface (inclined curved surface) is used as the reference surface. This configuration enables the yarn layer formed on the winding body to have a conical front. The distance from the reference plane of the yarn feeding point for each yarn certainly remains the same. However, with this configuration, each of these yarns is fed onto the cone surface in front of the yarn layer by selecting the cone surface as the reference surface.

  In this warping method, it is mainly preferable that the yarn is not fed onto the conveying surface of the conveying device for a predetermined time when the fluctuation margin is not sufficient. During this predetermined time, the transport surface of the transport device can continue to move to such an extent that sufficient space is available for feeding the yarn again. Such a configuration certainly occurs rarely when a reasonable pattern design is performed. However, a configuration that can continuously move the transport surface of the transport device at a constant speed without the need to feed the yarns at the same time significantly expands the possibilities of partial warping.

  In the warping method, when the yarn is passed through the side of the winding body and fed to the core disposed on the shaft of the winding body during the predetermined time, a particularly preferable embodiment is provided. Become. In this case, it is not necessary to interrupt the supply of the yarn. For example, the rotary creel can be continuously rotated. This simplifies the control when constructing the yarn layer.

  In the warping method, as an advantageous configuration, the yarns are fed before and after the at least one dividing rod in a predetermined order during winding, and the dividing rod depends on the movement of the yarn guide in the axial direction. It is configured to be moved. In particular, problems may arise when the dividing rod is unable to "catch" the yarn correctly when it is desired to obtain a large margin of variation with the yarn guide. As used herein, the term “dividing rod” is used in this case as a superordinate concept of a lead rod and a cutting rod. One dividing rod usually has a finger piece at its end, to feed the yarn in front of the dividing rod, ie radially outward with respect to the winding body or the yarn behind the dividing rod. This finger piece can be swung into the path of movement of each thread to run. The length of this finger piece is limited for technical reasons. However, when the entire dividing rod can be displaced, this problem is virtually no longer an important issue. That is, in any case, the yarn is securely gripped and fed before and after the dividing rod in a predetermined order. In this case, if the movement of the yarn guide and the movement of the dividing rod are synchronized with each other, it is naturally advantageous. However, this synchronization does not mean that the dividing rod must follow each movement of the yarn guide.

Regarding the invention of the pattern warp partial warper according to the present invention,
In the pattern warp partial warper, it is preferable that the yarn guide and the dividing rod have a drive control device capable of synchronous control. In this configuration, the information on where the yarn supply portion of the yarn guide is located must be available to the yarn guide drive control device. However, this information can also be used to properly control the dividing rod. This does not mean that the dividing rod and the thread guide must continuously perform a synchronous movement. The dividing rod has a certain length that allows the yarn to be securely gripped. It is sufficient to position the dividing rod so that the yarn movement path is within the length of the dividing rod. The common drive control device can be variously configured. It is possible to control both the drive motor for changing the yarn supply position of the yarn guide and the motor for changing the position of the dividing rod by the same control device. However, if the driving device for the dividing rod is more accurately described to the driving device for the yarn guide, it can be connected to the positioning driving device, for example, in a master / slave control relationship.

  In the pattern warp partial warping machine, a plurality of dividing rods may be mainly disposed on the winding body, and the winding body may be configured to be coupled to a common entrainer. In general, a plurality of rods called “Leeds rods” or “cutting rods” are arranged on the winding body. For the sake of simplicity, all rods will be referred to as “dividing rods” without distinguishing between a lead rod and a cutting rod. Control can be greatly simplified when all the dividing rods can be driven simultaneously and similarly. For this purpose, an entrainer is provided.

  Preferably, in the partial warp for pattern warp, at least one dividing rod is configured to be fixable to the entrainer at different axial positions. If comprised in this way, when using a dividing rod, a softness | flexibility will increase. It is no longer necessary to provide a specific dividing rod for one yarn pitch at the beginning of the yarn layer cone and another dividing rod for the yarn pitch at the end of the cone. Virtually any dividing rod can be selected by positioning at different positions in the axial direction.

  In the pattern warp partial warper, the entrainer may be configured to be disposed mainly on the front surface (end surface) of the winding body that does not supply the yarn. In this configuration, the entrainer then does not interfere with the yarn supply. Rather, the yarn can be supplied relatively freely as is conventional.

  Further, in the above-mentioned partial warp for warp warp, it is advantageous that an entrainer is coupled to a screw spindle, and this screw spindle has a rotary drive device. With such a drive, it is certainly only possible to achieve a relatively slow displacement of the dividing rod. But this is enough. This is because the yarn supply location of the yarn guide is only changed at a limited speed.

  In the pattern warp partial warper, the driving device for the single or plural dividing rods can be constituted by a linear driving device.

  Further, in the partial warp for the pattern warp, each dividing rod can have its own drive device.

  Hereinafter, the present invention will be described in detail based on preferred embodiments with reference to the drawings.

1 has a warping drum 1 as a winding body, and a circumferential surface of the warping drum 1 has a conveyor belt (in parallel with a rotation axis moved in the direction of arrow 3). (Conveying device) 2 is arranged, and dividing rods 4, 5, 6 are arranged in parallel to the rotation axis. The dividing rod can also be referred to as a lead rod or a cutting rod, depending on their function.
1, the outer surface of the conveyor belt 2, that is, the outer surface of the conveyor belt 2 in the radial direction of the warping drum 1 serves as the conveyor surface of the conveyor device.

  The rotary creel 7 has a rotating body 8, which carries a large number of bobbins 9 and is driven (rotated) by a motor 10. Instead of this configuration, the rotary creel 7 can be directly driven via the drive shaft 17 of the partial warper.

  A yarn guide 13 is provided at one end of the warping drum 1, and these yarn guides 13 are driven in synchronization with the rotating body 8 of the rotary creel 7. The yarn guide 13 draws the yarns 2a and 12b from the rotary creel 7 and feeds them onto the conveyor belt 2 and selectively onto or below the dividing rods 4, 5, and 6. The yarns 12a and 12b may be made of different types of yarns. However, generally, it consists of a plurality of yarn groups 12a and 12b each having two or more of the same type of yarn.

  The rotary creel 7 can have up to 16 bobbins 9, that is to say, up to 16 yarns can be fed onto the warping drum 1 simultaneously. Each of the yarns can be composed of different yarns, but a plurality of the same yarns can be warped. By means of the rotary creel 7 it is possible in principle to wind all the yarn from the rotary creel 7 around the warping drum 1 simultaneously.

  FIG. 2 shows that the yarn guides 13 are respectively attached to levers 14 which extend radially via arms 11 arranged so as to be able to cover the edges of the warping drum 1 (see FIG. 1). It represents the status being displayed. One end of the lever 14 is held in a hub 15, and the hub 15 is rotated by a motor 10 (see FIG. 1) of the rotary creel 7 via a cardan shaft 17. Here, it is assumed that each of the members rotates counterclockwise (in the direction of arrow 18 in FIG. 2).

  The conveyor belt 2 continuously moves at a constant speed when winding the yarn, and how to set this speed will be described later.

During the warping process, that is, when the yarns 12a and 12b are guided around the warping drum 1, the warping drum 1 is held non-rotatable. As a result, coupled with the movement of the conveying belt 2, A yarn structure composed of a plurality of yarns arranged in the direction of arrow 3 in FIG.
In the rewinding process that is subsequently performed after the warping, a plurality of yarns are simultaneously drawn from the warping drum 1 having the rotating yarn component, and thus a warp yarn for a pattern composed of a large number of yarns is obtained. can get. The dividing rods 4, 5, 6 then serve to allow the yarn layers to be cut in the correct position and to draw individual yarns as a juxtaposed yarn sheet.

  In order to increase the variety of patterns of the warp for the pattern, and for reasons explained later, during winding pauses, which may be indispensable at times, such as is known, for example, from DE 198 45 245 In addition, individual yarns can be removed from the warping process. As an alternative, the yarn guide 13 can be moved from the outside in the radial direction of the warping drum 1 and the yarn not involved in the weaving is known from DE 10061490. As shown in the figure, it can be wound around a winding core extending coaxially with the rotational axis of the yarn guide 13.

  In FIG. 3, the configuration in which the yarn guide 13 is attached to the arm 11 is shown in an enlarged manner. The arm 11 is steplessly or stepwise by a motor 19. Is displaceable mainly in the warping direction, that is, in the direction indicated by the arrow 3 in FIG. The motor 19 is controlled and operated by a control device 21 so that the following action can be achieved.

  As can be seen from FIG. 4, the yarns are not warped individually, but are warped as so-called yarn bands. One yarn band includes N yarns, where N is an integer in the range from 1 to the maximum number of equipped bobbins 9 held by the rotary creel 7. In the illustrated embodiment, one thread band can have 1 to 8 threads. In order to distinguish the individual yarn bands from each other in the figure, in FIG. 4, the yarns of the first yarn band are shown as double circles, and the yarns of the second yarn band are shown as simple circles.

  The conveyor belt 2 is moved in the direction indicated by the arrow 3 in FIG. At that time, it is desirable to prepare a space for the next yarn band 60 after the winding of the first yarn band 50 is completed.

  However, if each individual thread band has a different number of threads, a space having a width corresponding to a different thread band width is required on the conveying belt 2. The distance to which the conveyor belt 2 is fed during the warping of one yarn band is indicated by a one-dot chain vertical line in FIG. From FIG. 4B, it can be recognized that one yarn of the first yarn band 50 remains in the space planned for the second yarn band 60. However, since the second yarn band 60 has only two yarns instead of four, a space smaller than that of the first yarn band 50 is sufficient. That is, the large space required by the first yarn band 50 is compensated by the second yarn band 60 that requires only a small space.

  Such warping is realized by appropriately controlling the individual yarn guides 13 only schematically shown in FIGS.

  First, a desirable speed of the conveyor belt 2 is obtained. At this time, it is assumed that the conveying belt 2 has moved by a predetermined warping width when the warping of the entire pattern warp is completed. The warping width is then divided by the number of yarn bands or the width of one repeat, or the number of yarn bands in the repeat, so that when one yarn band is wound, the conveyor belt 2 is averaged. It becomes clear what distance can be moved. That is, the average speed (weighted average value) of the conveyor belt 2 in the warping process becomes clear. The average speed thus obtained of the conveyor belt 2 is kept constant during the warping process as the moving speed when the subsequent warping process is performed.

By the way, in the actual warping process, the individual yarn bands, regardless of whether the individual yarn bands include different numbers of yarns or because the individual yarns have different widths or thicknesses. If they have different widths, one yarn band will require more space and another yarn band will require less space. However, even if the speed of the conveyor belt 2 is set to an average value, each thread band requires one space so that the individual thread bands can be wound side by side as shown in FIG. It can be assumed with high probability that they will cancel each other out in the warp warp part. Unevenness on the surface of the yarn layer placed on the conveyor belt 2 is thus prevented.
In a special case, if the cancellation is not possible, i.e. if one thread band requires more space than is formed by the movement of the conveyor belt 2, sufficient space is provided for a certain period of time, i.e. again. The winding operation may be stopped in a state in which the movement of the conveyor belt 2 is continued until the operation is completed.

  During the winding operation, the individual yarns a, b, c, d are arranged in the yarn band 50 in exactly the same way as the yarns e, f in the yarn band 60 by the corresponding setting of the yarn guide 13. The Further, in the winding layer in which individual yarn bands are continuous (three winding layers are shown in FIG. 4, an actual pattern warp naturally has much more winding layers), The operation of the yarn guide 13 is controlled so that it is guided along the inclined curved surface (front surface) 70 of the cone having an angle α. For example, this cone can be formed into a cone by providing a corresponding conical stop member on the conveyor belt by a technique not shown in detail. However, it can be accepted that at the edge of the first yarn band, the yarn is fed with a slightly reduced yarn tension, and the necessary cone is gradually formed only after that. The inclination angle of the cone may be in the range of 6 to 26 °, with a cone angle of 18 ° or less being a particularly preferred angle.

  When the width of the yarn band 50 is large, the yarn guide 13 must move closer to the start end (right end in FIG. 4) side of the conveyor belt. This becomes clear when FIG. 4 (b) is compared with FIG. 4 (c). In FIG. 4C, two more yarns g and h are added as another yarn band 80. In other words, the yarn g is fed to a position farther from the starting end than the yarn e of the yarn band 60. By the way, when other yarn bands are added and the space required for these yarn bands is smaller than the section S in which the conveyor belt 2 moves when winding one yarn band, the yarn guide 13 is further shown in FIG. It must always be displaced in the direction of the arrow 3 so that the individual yarns g, h can be fed correctly onto the conveyor belt 2.

  However, after the selection of the average conveying speed, the wide yarn band and the narrow yarn band, or the thick yarn band and the thin yarn band, or the individual thick yarn and the individual thin yarn alternate, and the yarn guide 13 Can be rubbed in a certain range that can be covered with the desired arrangement of the yarn bands arranged on the conveyor belt 2. The range that the yarn guide 13 can cover can be, for example, over a section of 4 cm (40 mm), and can be carried out by displacing the yarn guide 13 in the axial direction from the “neutral position” over a section of +/− 20 mm. it can.

  At that time, in order to be able to form the inclined curved surface 70, it should be taken into consideration that the yarn guide 13 originally requires a certain displacement.

  By the way, by appropriately selecting the degree of coverage of the rotary creel 7, it is possible to further consider the difference between individual yarn bands from becoming excessive. For this reason, data relating to required sampling is input to the computer before the production (warping) of the warp for the pattern. It is desirable for the computer to determine what yarns are preferably combined into one yarn band. At that time, for example, when the same yarn in the yarn band is required at different positions, or when the same yarn appears several times in one yarn band, one yarn at a plurality of positions in the rotary creel 7 It is well possible to schedule.

The greater the possibility of change when feeding the yarn onto the conveyor belt 2, the greater the variation margin will eventually be, i.e. the individual belts are fed so that the required uniformity occurs in the yarn layer. In order to feed the yarn 2 above, a larger space for moving the yarn guide 13 back and forth is required.
This is schematically illustrated in FIG. The arm 11 on which the yarn guide is disposed has a length L of, for example, 200 mm. In order to be able to wind the cone 80, the arm 11 must be able to displace the thread guide 13 over the section S1. The section S1 is, for example, 60 mm.

  In order to be able to form this cone 80 at different positions while the conveyor belt 2 continues to run, the arm 11 must additionally be able to be displaced by an amount corresponding to the section S2. The section S2 is 40 mm, for example. In other words, the cone can be formed in this case by reciprocally sliding the arm 11 +/− 20 mm, thus providing a “variation margin” sufficient to place the individual thread bands. However, in most cases, about 20 mm is sufficient for the section S2. For example, the displacement may be reciprocated by +/− 10 mm.

  FIG. 6 shows two dividing rods 5, 6 corresponding to FIG. 5, each having a finger piece 81 at the end and feeding the yarn onto the dividing rod 5 or the dividing rod 5. The finger piece 81 is movable in the direction of the arrow 82 in order to feed the yarn underneath. The dividing rod 6 is configured in the same manner. It can be seen that most of the yarn layer 83 is above the dividing rod 5 and some yarn 84 is located below the dividing rod 5.

  There is a certain limit to the range in which the finger piece 81 can move. It is relatively difficult to cover the entire movable range of the thread guide 13 with the movable range of the finger piece 81. For this reason, the range in which the dividing rods 5 and 6 can be displaced in the axial direction is configured to be displaced by, for example, the section S2. At the same time, the dividing rods 5 and 6 always allow the finger pieces 81 to be positioned so as to be able to grip the thread irrespective of the position of the thread guide 13. In that case, one dividing rod 5 is usually used for the start of the cone and one dividing rod 6 is used for the end of the cone, so that the dividing rods 5, 6 are threaded. It is a point that it is sufficient to slide only within a range corresponding to the fluctuation margin, not over the entire movable range of the guide 13.

  For sliding, the dividing rods 5 and 6 are connected to a common entrainer 85, which meshes with a screw spindle 86 that is rotationally driven by a rotational drive device (motor) 87. When the spindle 86 rotates, the entrainer 85 moves forward or backward in the axial direction.

  Each dividing rod 5, 6 has a specific connection point 88, and a lever of a follower 85 (not shown in detail) can be engaged at these connection points. Further, the individual dividing rods 5 and 6 can be fixed at different positions in the axial direction in the entrainer 85.

  The rotation drive device (motor) 87 is configured to be controlled by the same control device 21 that also controls the drive device 19 of the arm 11. With this configuration, it is possible to easily position the dividing rods 5 and 6 so that the finger pieces 81 can be engaged with each other in the movement path of the yarn to be placed on the transport belt 2. Become.
