DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for directly processing yarns such as a weaving machine, a warping machine, and the like, or a device for winding and collecting yarns such as a bobbin winder. The present invention relates to a creel for supplying untwisted yarn by double twisting.

[0002]

2. Description of the Related Art Conventionally, in order to manufacture various kinds of belt-like woven fabrics such as a safety belt and a sling belt using a twisted yarn as a warp yarn, a required number of twisted yarns are wound around a beam, or weaving is performed. A method of winding the bobbin on a bobbin, disposing the bobbin on a creel, and supplying a twisted yarn from the creel is adopted.

[0003] In the case of weaving using a twist yarn as a warp yarn, there are the following problems. That is, the twisting process itself is generally not performed in a fabric maker, but is usually requested to an external twister. Therefore, despite the necessity of changing the twist degree according to the texture required for each fabric depending on the application and yarn specifications, even if the twist is found to be defective after the twist processing, the substantial change in the twist degree is not I had to use it as it was. Further, twisted yarns of the same length are not necessarily wound on each bobbin, and the bobbins vary and waste of twisted yarns occurs.

Further, the length of the twisted yarn wound on the bobbin is at most one half, usually one third, longer than the length of the original yarn of the large package. The replacement of the bobbin and the thread knotting are troublesome, and the knot portion is defective depending on the use of the product, and some of the knot portions have to be discarded. As described above, in the case of weaving a woven fabric using a twisted yarn as a warp yarn, there are many problems in comparison with a case where an untwisted yarn described below is directly supplied from a creel to a loom.

That is, when weaving an untwisted yarn as a warp yarn directly from creel, there is no need to connect the original yarns during weaving in order to use the original yarns of the large package as it is, and there is no need for a rewinding process or a straightening process. No need for a process
Furthermore, although the production efficiency is much better than the former case because it is not necessary to send the raw yarn to an external twister and request twisting processing, the product is less twisted because it is non-twisted. The texture is weak and the texture is limited.The fabric is weak against abrasion.There is a slight problem in quality.In addition, depending on the type of yarn used, the filament yarn breaks during weaving and tends to fluff. There is an annoyance that must be restored.

In order to solve the above problem, the present inventor disclosed in Japanese Patent Application No. 57-029084 a twisting device having a structure similar to a flyer mechanism for each bobbin wound with an untwisted yarn. A creel has been proposed in which untwisted yarn is sent and twist is added to the untwisted yarn at the same time. According to the present invention, the purpose of twisting the untwisted yarn of the large package and supplying it to the loom can be achieved, but there has been a problem that the equipment cost is large.

Therefore, the present inventor has further proposed Japanese Patent Application No. 60-1.
No. 89847 proposes a creel using a ring and a traveler for a twisting mechanism with the aim of achieving the same effect at a relatively small capital investment cost, and has a simpler structure than that of a structure similar to the flyer mechanism. The cost was relatively low. However, even though the capital investment cost has become lower, there is a drawback in that it requires costs that cannot be said to be overwhelmingly lower than the cost of twisting processing, and it has not led to a drastic solution to the problem. .

The above two known examples disclose the use of a configuration in which a spindle drive transmitting means, which is a main part of a twisting mechanism, is combined with a shaft and a bevel gear in each of the embodiments. The complexity made it difficult to reduce capital investment costs. Also,
Japanese Patent Application No. 60-189847 discloses a technique of supplying twisted yarns in two directions, S twisting and Z twisting. However, a method in which a single motor is used to change the rotation direction by changing the belt and a two-series method are used. No mention is made of an example in which a drive device is used, and that the number of rotations, that is, the twist degree is changed over a plurality of times.

[0009] Further, the above two known examples only use a so-called straight paper tube (cylindrical paper tube), and only use a tape wound in a so-called straight paper tube (cylindrical paper tube). Nothing is said about the case using a paper tube or aluminum pan. There has been a demand for a creel provided with a twisting device capable of using such a wound yarn. Further, in the above two conventional examples, a conventional woven fabric using a twisted yarn has a twist degree of about 100 t / m at 1000 d, for example, 150 t / m,
Since the twist degree is about 80 t / m at 0d, it is assumed that the rotation of the spindle is set to a relatively low rotation (300 rotations / minute as a standard).

Therefore, even if the bobbin is supported and fixed on the spindle and rotated, there is no problem with a simple mechanism. However, when such a creel is employed in a woven fabric having a low density of wefts, such as a so-called blind weave, the weaving speed is high. At such a low rotation speed, the degree of twist added to the yarn is insufficient and almost no twist occurs. Absent. Further, there has been a problem that it is impossible to cope with a case where the warp yarn of the woven fabric is to be a strongly twisted yarn.

[0011]

SUMMARY OF THE INVENTION It is an object of the present invention to remedy the drawbacks of the prior art, to increase the selection range of the bobbin shape in which the target untwisted yarn is wound, and to improve the conventional ordinary knitted fabric. Equipped with a twisting device that can be applied to a wide range of demands that can be applied to woven fabrics with low weft density such as blind weave and high weaving speed or warp woven fabrics with high twisting degree Another object of the present invention is to provide a creel that can greatly reduce equipment costs, and further provide a creel that can be used as a twisting device such as twisting and winding the yarn itself.

[0012]

The present invention employs the following technical configuration to achieve the above object. That is, a plurality of spindles to be rotated by appropriate driving means are arranged in the frame portion, bobbins around which untwisted yarns are wound are set on each spindle, and the yarns drawn from each bobbin are twisted and the plurality of spindles are rotated. In a creel in which twisted yarns are aligned so as to be parallel to each other to form a sheet, each of the spindles is composed of a single horizontally arranged rotating shaft, and a central portion of the rotating shaft is fixed to a predetermined position. A portion for setting a bobbin on which the untwisted yarn is wound is provided on both sides of the rotary shaft, and is rotatably attached to the frame portion of the creel via a bearing, and a central portion of the rotary shaft. A double twisting mechanism is provided at a portion where the bobbin around which the untwisted yarn is wound is set. It is there creel.

[0013]

The creel provided with the double twisting mechanism according to the present invention has the following technical configuration, and thus has the following effects. That is, in a creel equipped with a conventional twisting device, the bobbin is rotated, so it is necessary to mount the yarn so that the yarn is unwound in a direction opposite to the rotating direction (in a straight paper tube, the yarn is set in the opposite direction). In the case where the direction of unwinding from the bobbin is one direction (for example, a tapered paper tube), it is necessary to prepare in advance so that the unwinding direction is reversed. By adopting the twisting mechanism, the bobbin is stationary, so the rotation direction is not limited by the unwinding direction of the yarn in any of the S and Z twisting directions. is there.

Further, the drive means of the spindle is, for example, a single and commonly used motor and the power of the motor is transmitted through an appropriate drive transmission means such as a belt or a chain.
The drive system is configured by a drive system having a configuration for transmitting to the rotary shaft of each spindle.It is also possible to prepare a single drive system or a plurality of drive systems having such a configuration. In the case where the material and the fineness of the original yarn are different, it is possible to easily change the twist degree and the twist direction for each series according to each requirement when the material and the fineness of the original yarn are different.

A device 14 for extracting untwisted yarn from the creel 1 having the double twisting mechanism and supplying the twisted yarn according to the present invention is a device for processing a gathered twisted yarn such as a loom or a knitting machine, or a gathered twisting machine such as a warping machine. It is desirable to be a device for winding a twisted yarn.

The above-described double twisting mechanism 21 according to the present invention
If the configuration of the creel 1 having
A support that supports the bobbin wound with the untwisted yarn 2 and stands still;
Inside the bobbin support 10, there is provided a rotating hollow shaft spindle 8 and a double twisting mechanism 21 for pulling out the yarn from the base of the spindle 8 or the rear or intermediate position of the bobbin to perform double twisting. The creel 1 is configured to perform a twisting process in a process of extracting the untwisted yarn 2 from the bobbin 3 and supplying the untwisted yarn 2 to a predetermined device 14. 2 and the top plan view shown in FIG.
A spindle 8 having at least two bearings in a central portion thereof and having hollow shaft portions 22 on the left and right sides thereof, is configured as a single rotating body via a rotating shaft portion 8 ′, and a creel side surface. When viewed from the side, a plurality of the spindles 8 are arranged in parallel in the horizontal direction, and a plurality of parallel groups of the spindles 8 are provided in the vertical direction as viewed from the side of the creel. 7

In the creel 1 according to the present invention, a twisting device which adopts the above-mentioned new technology and is different from the conventional creel and which can cope with a case where the number of twists per unit time is extremely large is provided. The creel provided.

The structure of the creel according to the present invention will be described in further detail with reference to FIGS. 1 and 2. FIG. 1 is a side view of the creel 1, and FIG.
FIG. As is clear from FIGS. 1 and 2,
A plurality of spindle groups 8 are arranged in the frame portion 18 of the creel 1, and two rows of spindle groups arranged in the horizontal direction of the spindle groups constitute one block B 1, B 2, B 3, respectively. A single common motor 6 is provided at the left end of each block, and a drive means 7 such as a belt or a chain engaged with the single motor is driven by a group of spindles 8 forming each block. To rotate the spindles 8 in the same direction.

In the present embodiment, particularly when a belt is used as the driving means 7, it is desirable to provide the tension pulleys 71 at predetermined intervals.
It is desirable that the belt 7 and the central portion 8 'of the spindle portion always contact with a predetermined contact pressure. When the belt 7 is stretched on each spindle 8, the drive motor 6 provided for each spindle block moves the position to a position shown by a broken line. It is desirable that the belt be moved to the position indicated by the solid line in order to apply the tension of the belt to the belt.

As shown in FIG. 2, the spindle 8 has at least two bearings 20-1 and 20-2 at the center in a plan view of the creel body from above, and As is apparent from FIG. 3 which is an enlarged view of the portion, a hollow shaft portion 22 constituting a hollow fiber passage which is a hollow portion on each of the left and right sides thereof, and a guide eyelet for pulling out the yarn from the base of the hollow shaft portion 22 16 and an outlet guide 11.

It goes without saying that the hollow shaft may extend through the spindle shaft. In this case, the guide eyelet 16 is provided at an appropriate position in the middle of the hollow portion. A bobbin support 10 is provided outside the hollow spindle 9 via a bearing, and supports the bobbin 3 on which the untwisted yarn 2 is wound.

In this configuration, the bobbin support 10 is kept stationary by the weight 17 even when the spindle 8 rotates, so that the bobbin 3 wound with the untwisted yarn 2 remains stationary even when the creel is running. ing. The left and right hollow spindles 9 and the bobbin support 10 are configured as a unit that can be attached and detached from the rotary shaft 8 ′ at the center, and can be replaced with a unit that matches the shape of the yarn package as necessary. good.

The unit exchange is an embodiment of the present invention and is not a basic essential condition, and may be fixed. In the structure of FIG. 2, the rotation direction of one spindle 8 naturally rotates in one direction, but when viewed from the drawing direction of the untwisted yarn 2 on the left and right sides, the right side (A) in FIG. 2 and the left side (B) of FIG. 2 rotates counterclockwise.

Therefore, on the right side (A) of FIG. 2, the untwisted yarn 2 drawn into the hollow spindle 22 is subjected to the first S twist by the rotation of its base, and the yarn guided from the outlet guide 11 is the outlet eyelet. A second S twist is added between the twelve. On the other hand, on the left side (B) of FIG.
Although not shown, since the rotation direction of the spindle is counterclockwise, the untwisted yarn is subjected to two twists in one rotation of the spindle in the same route as the right side.

Accordingly, when the rotation direction of the spindle 8 is opposite to that in the example of FIG. 2, the right side is Z-twisted and the left side is S-twisted. Note that all the ranges in which the driving means are interlocked have opposite twist directions on the left and right, and the rotation speed, that is, the twist degree is the same. Hereinafter, a more specific example of the creel according to the present invention and its operation will be described in detail with reference to the drawings.

That is, in FIG. 1, the required number of bobbins 3 around which the untwisted yarn 2 is wound (6 in the side view shown in FIG. 1).
0, 60 on the opposite side, a total of 120), pull out the untwisted yarn 2 from each bobbin 3 and process it into a twisted yarn before reaching the respective outlet eyelets 12,
The twisted yarn group 4 is supplied in parallel to a predetermined device 14 (for example, a needle thin loom in FIG. 1) via a tension roller 13.

The arrangement in the lattice in the drawing is such that when the second twist is applied, the twisted yarn forming ballooning in the spindle and ballooning in the adjacent spindle are formed. Is a ballooning control part that is effective to prevent the twisted yarn from contacting
An anti-ballooning member 5 composed of a woven fabric, a braid, a film, a nonwoven fabric, a plate, a rod, or the like.

If the predetermined device is a warping machine, the warping speed must be reduced to warp using a creel equipped with a conventional twisting device. This is preferable because warping can be performed at a higher speed. FIG.
Is a creel 1 having a double twisting mechanism according to the present invention.
This shows a configuration of a specific example of the double twisting mechanism 21. When a predetermined device 14 (a loom, a warping machine, or the like) is operated, the spindle 8 of the creel 1 starts rotating in synchronization with the operation. When the yarn advances, the untwisted yarn 2 is drawn from the bobbin 3 that is stationary by the operation of the predetermined device through the eyelet 25 into the yarn passage 22 provided inside the hollow spindle 8 provided at both ends of the spindle 8. It is.

At this time, in order to prevent the unwound yarn from the bobbin 3 from hanging down and interfering with the ballooning of the untwisted yarn 2 in another adjacent spindle 8 during the second twisting, It is simple and effective to cover the yarn with a net or a bag. The untwisted yarn 2 is guided to the spindle base, is subjected to a first twist while reaching by the guide eyelet 16, and is further subjected to the outlet guide 1 from the guide eyelet 16.
A second twist is applied through 1 to the outlet eyelet 12.

The shape and structure of the guide eyelet 16, the outlet guide 11, the eyelet 25, etc., the method of mounting the hollow spindle unit, and the like are merely examples, and the present invention is not limited thereto. As described above, in the present invention, in order to prevent the ballooning from spreading during the second twisting process and interfering with the ballooning of the untwisted yarn 2 in another adjacent spindle 8, each adjacent balloon is prevented. Preferably, an anti-ballooning plate 5 is provided between the spindles 8 so that one spindle 8
In this case, it is possible to prevent interference between ballooning formed by the yarn being twisted and ballooning of an adjacent yarn. Needless to say, a function other than a plate, for example, a cylinder, may be used. The difference between the creel 1 having the double twisting mechanism according to the present invention and the conventional so-called double twister is as follows. (1) There is a pair of twisting devices on the left and right of one spindle arranged horizontally. In addition to rotating them at the same time, the overall structure is simple, and the cost per spindle is low.

(2) A guide eyelet 16 and an outlet guide 11 are provided on both sides of a central shaft, and a hollow spindle 9 and a bearing 15 and a bobbin support 10 outside the hollow spindle 9 are attached to this portion. Units can be replaced as needed. (3) In a process in which the twisted yarn drawn from the creel 1 is supplied to a predetermined device (such as a weaving machine or a warping machine) 14, a tension roller device that usually equalizes the warp yarn length and makes the tension uniform is provided. Since it passes through, there is no need for precise tension adjustment unlike a twisting machine. If necessary, a tensor unit may be fitted into the end of the bobbin and used.

(4) The range of the number of rotations is very wide, and the range of application is wide. (5) Since each spindle is concentrated, ballooning interference can be prevented with a simple and inexpensive structure. In the creel according to the present invention, the twisted yarn is supplied to a predetermined device (a loom, a warping machine, etc.), and the required number of twists as the twisted yarn is derived from the rotation speed of the spindle and the bobbin. It is determined by the drawing speed of the untwisted yarn.

The drawing speed of the untwisted yarn depends on the winding speed of a predetermined device (a loom, a warping machine, etc.). For example, if the number of revolutions of the needle narrow loom is set to 2400 revolutions / minute, and the weft density is 3 cm / 1 pick with a blind weave fabric, the weaving is performed at 72 m / minute. 100t /
When applying a twist of m, the spindle rotation is about 7200 revolutions / minute in a normal twisting apparatus, but may be 3600 revolutions / minute in a double twisting method.

At the same spindle rotation speed, 100 t /
When warping while adding a twist of m, winding may be performed at a speed of 72 m / minute. The winding speed of a predetermined device (loom, warping machine, etc.) is not constant, and the twist must be changed according to the material and fineness. Therefore, in the present invention, as described above, the spindle It is necessary to have a configuration capable of rotating the spindle in an arbitrary direction and a configuration capable of giving an arbitrary number of rotations to the spindle.

The yarn wound on the bobbin may be a non-twisted yarn or a yarn previously supplied as a sweet twisted yarn by a manufacturer (included in the category of untwisted yarn in the present invention).
There is no particular limitation. Also, the fineness of the untwisted yarn is not particularly limited, and is appropriately selected according to the use in which the yarn is used. If necessary, the same effect as a ply-twisted yarn can be obtained if the original yarn is plied.

In the present invention, the plurality of twisted yarn groups 4 usually drawn from the creel all have the same twist and the same S / Z twist, but are equipped with a plurality of spindle drive systems. Thereby, it is also possible to partially change the twist degree and to change the distribution of S / Z twists as necessary. The driving device 7 for the spindle 8 will be described with reference to FIG. A number of spindles 8 (not shown) are rotationally driven by a belt by a motor 6 and a drive transmission device 7. FIG. 1 shows that ten spindles 8 are arranged in parallel in the horizontal direction when viewed from the side of the creel, and the parallel group of the spindles 8 is provided in six stages in the vertical direction when viewed from the side of the creel. Although the example in which each of the three motors interlocks the two-stage spindle group in the horizontal direction is shown, the entire spindle is rotated in a predetermined direction by a single motor and driving means, and the number of rotations is reduced. It may be configured to be variable, and the position of the motor may be above or below the creel. In order to arrange and use the S / Z twist at a predetermined width on a single band of fabric, it is easier to treat the motor if it is arranged rearward as shown in FIG.

As a method for controlling the rotation speed of the spindle, the rotation speed of the AC general-purpose motor 6 is controlled by changing the frequency through an inverter through a control panel.
The frequency is changed in the range of 0 to 120 Hz. In this case, it is theoretically possible to set the frequency to 0 to 3600 rpm. In order to convert the rotation speed into a wide range and efficiently, the high rotation range is operated by the direct drive means from the motor when the high rotation range is mainly used, and the motor is used when the low rotation range is mainly used. Preferably, the speed range is continuously variable or a fixed (eg, 1/15) transmission is connected.

If necessary, the high rotation range and the low rotation range can be switched and used. Alternatively, a variable speed motor can be employed to control the number of revolutions. The design of the selection of the motor, the driving means, the selection of the transmission and the like are well known in the prior art and will not be described in detail.

By employing the above-described configuration, it is possible to vary the rotation speed of the spindle from 0 times / minute to a wide range of about 3600 times / minute, and the use range of the twisted creel is expanded more than before. Thus, the number of twists can be easily changed. Of course, if the spindle is not driven using the creel of the present invention, the untwisted yarn can be pulled out and supplied to a predetermined device.

In FIG. 1, one motor system drives two sets of spindles in the horizontal direction. However, by providing driving means in multiple stages, one motor system drives many stages. It is also possible. The distance between the spindles is determined by a commonly used bobbin and a winding amount of a raw yarn wound on the bobbin. In the specific example described above, the plurality of spindle groups arranged on the creel are composed of one motor 6 provided on the side end of the frame 18 and a belt arranged horizontally.
Although an example is shown in which a drive system composed of a chain or the like drives and controls the spindle group for each horizontal stage, in the present invention, one motor 6 provided at the side end of the frame 18 is connected to one motor 6. It is also possible to control the rotation of a predetermined group of spindles by a driving means 7 comprising a driving system composed of a belt, a chain and the like arranged in a vertical direction.

In the above specific example of the present invention, the above-mentioned object can be achieved. However, in the case where a belt is used as the driving means, no matter how the tension is controlled, slip will not occur. Occurs, the energy loss is high, the driving efficiency is reduced, and there is a problem that it is not suitable for high-speed driving.
Also, when using a chain as the driving means,
Similarly, the energy loss was high, and it was found that it was not suitable for speeding up because of the problems of weight and noise.

Therefore, the present inventors have conducted intensive studies in order to solve such a problem, and as a result, have found that it is effective to directly dispose the drive means 7 for each spindle 8. Thus, it has been found that it is desirable that the driving means 7 be constituted by motors 60 directly and individually joined to the respective central portions 8 ′ of the rotating shafts of the respective spindles 8.

That is, in the present embodiment, as shown in FIG. 5, the driving means 7 comprises a motor 6 to which each of the rotating shafts 8 'of the respective spindles 8 is individually directly joined.
This is constituted by a motor that is integrated with the rotation shaft 0. That is, to explain the above-described embodiment according to the present invention in more detail, the driving means 7 is constituted by a motor 60 directly connected to the central rotating shaft portion 8 ′ of each spindle 8. 60 are grouped into a single or a plurality of drive systems, and are controlled by an appropriate control circuit (not shown) provided for each drive system.
The configuration is such that the rotation direction and the number of rotations of each spindle included in the drive system can be converted independently of other drive systems.

Further, the motor 60 in this embodiment is
A stator portion 62 having a stator coil portion 61;
It is constituted by a rotating portion 63 having a rotor core portion formed by laminating magnetic steel plates, and a central rotating shaft portion 8 ′ of the spindle 8 is fitted to a rotation center portion of the rotating portion 63. Have In FIG. 5, for example, the motor 60 is such that a rotating part 63 having the rotor core part constitutes a three-phase squirrel-cage induction motor having a squirrel cage shape, 64 is a bearing, 65 is a bracket, 66 Denotes a stator coil insulator, 67 denotes a frame, 68 denotes a rotor end ring, and 69 denotes an internal fan.

In the embodiment according to the present invention, the motors 60 having such a configuration are individually arranged on the respective spindles 8 so that the respective spindles 8 can be directly started, stopped, or controlled by the motors 60. The rotation can be controlled in a predetermined rotation direction at the rotation speed. Specifically, each of the motors 6 provided on all spindles
It is possible to arrange an operation control device including an inverter at 0 and execute the rotation control of the motor 60 based on the frequency control.

In such a case, the operation is performed for each spindle 8,
It is possible to control stop and the like, and it is also possible to drive and control only a necessary spindle in response to a change in the number of yarns. In addition, soft start at the time of startup by frequency control,
In addition to the soft stop at the time of stop, the effect of being able to easily execute the emergency braking stop and the change in the number of revolutions is obtained.

Further, by using the motor 60 having such a configuration, the rotation speeds of the plurality of motors can be easily synchronized, so that the rotation speeds of the spindles can be easily synchronized. Become. In the present invention, the motors 60 provided on each spindle are individually driven and controlled as described above, whereas the motors 60 provided on a plurality of spindle groups are grouped as one group. The same operation control as described above may be executed collectively by a predetermined operation control device.

In this case, it is desirable to group about 20 motors 60 as a group in consideration of economic effects. FIGS. 6A to 6C show the arrangement of the spindles 8 in the creel 1 when the motor 60 according to the present invention is used, compared with FIGS. 1 and 2. FIG.

That is, FIG. 6A is a front view of the creel 1, FIG. 6B is a side view of the creel 1, and FIG. It is a top view. As apparent from FIGS. 6A to 6C, the frame portion 18 of the creel 1 includes a plurality of spindle groups 8.
Are arranged, and two rows of spindle groups arranged in the longitudinal direction of the spindle group are respectively arranged in one block B.
1, B2 and B3.

Since each spindle 8 is integrated with the rotating shaft of the motor 60, the motor 60
Since it is fixed to a predetermined frame 18 'by an appropriate fixing means, as shown in FIGS. 1 and 2, a bearing 20-1 for holding both sides of a center rotating shaft portion 8' of the spindle is provided. 20-2 becomes unnecessary. In addition, belt,
There is no need for a space in which a chain or the like is stretched or a tension pulley for adjusting the tension of the belt, so the space for that can be omitted.
Simplification and downsizing are realized.

In FIGS. 6A to 6C,
For the same parts as those shown in FIGS. 1 and 2,
1 and 2 are denoted by the same reference numerals, and detailed description is omitted. In the above specific example of the present invention, a plurality of spindle groups can be managed as a single group independently of other groups.
If the blocks B1, B2, and B3 in (A) are configured by different frames and each frame is slidable left and right, for example, the frame configuration changes according to the change in the number of spindles used. Can be
Further, since a space can be arbitrarily formed between the frames, the operator can easily enter the back side and the side surface of the frame, so that the replacement of the bobbin and the handling of a failure become easy.

As an example of the shape of the spindle 8 according to the present invention, the rotating shaft of the spindle 8 is such that the outer diameter of the central portion 8 'is the largest and the outer diameters of both ends are smaller. It is configured. The spindle 8 sets a bobbin around which an untwisted yarn is wound at both ends, and rotates the spindle at a predetermined number of revolutions. When the rotational balance is lost, the spindle vibrates, and in the worst case, Although there is a case where the spindle 8 is broken due to resonance, the vibration can be minimized by making the entire shape of the spindle 8 as described above.

In the specific example of the present invention, as described above, the yarn 2 unwound from the bobbin 3-1 wound with the untwisted yarn forms ballooning in the creel portion in the present invention. In order to prevent the ballooning from interfering with the yarn unwound from the bobbin 3-1 wound with the adjacent untwisted yarn or the bobbin wound with the adjacent untwisted yarn, an anti-ballooning plate 5 is provided, Although an example in which the bobbin 3-1 wound with an untwisted yarn is covered with a net or a bag fabric has been described, such a measure is inconvenient for mounting the bobbin 3-1 wound with the untwisted yarn on each spindle. In order to facilitate the operation, it is necessary to provide a certain space around each spindle. Therefore, there is a limit in reducing the size of the creel 1 and an obstacle to improving the working efficiency. That is It was also there.

In order to further solve the above problem, the present inventors set the yarn 2 unwound from the bobbin 3-1 wound with an untwisted yarn.
As a result of analyzing the occurrence of ballooning, as shown in FIG. 7, the variation due to the weight of the yarn, the unwinding speed of the yarn from the bobbin 3-1 wound with the untwisted yarn, the rotation speed of the outlet guide 11, etc. However, in many cases, the unwound yarn from the outlet guide 11 to the outlet eyelet 12 comes into contact with the wound layer of the bobbin 3-1 wound with the untwisted yarn at the point P1, or the untwisted yarn is wound. When the yarn 2 unwound from the bobbin 3-1 and enters the hollow portion 22 of the spindle 8 from the eyelet 25 comes into contact with the peripheral portion of the rotating twist pot 91 holding the outlet guide 11 at a point P2. It has been found that excessive friction is applied to the yarn to cause uneven twisting and, in some cases, the yarn may break.

As an example of a method for solving such a problem, it is conceivable to increase the diameter of the rotating twist pot 91. However, if such a configuration is adopted, it is necessary to take a considerable space around each spindle. Result Creel 1
Increases in size, causing a problem of a decrease in work efficiency and an increase in manufacturing cost. Therefore, the present inventors have studied to solve such a problem and have found that it is preferable to provide a bobbin holder 93 having a configuration as shown in FIG. 8 for each spindle.

That is, the bobbin holder 93 described above
The yarn receiving portion 9 formed integrally with the bobbin support portion 10 described in FIG. 4 and covering the lower surface of the untwisted yarn wound bobbin 3 # 1 held by the bobbin support 10.
4 and a yarn guide portion 95 provided integrally with the distal end portion F of the yarn receiving portion 94. Further, the bobbin holder 93 has, at the upper part of the bobbin holder 93, at least two-thirds of the total length of the bobbin 3 # 1 wound with the untwisted yarn held by the bobbin support. It is desirable that the space S is formed.

The bobbin holder 93 having the above configuration
Are mutually engaged with the rotating shaft portions having the hollow shaft portions 22 of the respective spindle portions 8 through the bearings 15 built in the bobbin support portion 10, and when the rotating shaft portions rotate, The bobbin 3-1 wound with the untwisted yarn is kept stationary, and the thread receiving portion 94 covering the lower surface of the bobbin 3-1 wound with the untwisted yarn held by the bobbin support 10 is attached to the bobbin support. 10 is formed and joined integrally, and the range covering the lower surface of the bobbin 3-1 is not particularly limited, but covers the bobbin 3-1 wound with the untwisted yarn at the maximum in a semicircular shape. It is desirable to be designed in such a way.

The thread receiving portion 94 is made of a material such as aluminum alloy or plastic, and also serves as a weight for stopping the bobbin around which the untwisted yarn is wound. It is necessary to have a certain weight. Further, it is desirable that the yarn guide portion 95 provided integrally with the distal end portion F of the yarn receiving portion 94 has an annular shape and a smooth surface.

As described above, the bobbin holder 93 according to the present invention allows the spindle 8 to rotate even when each spindle 8 rotates.
Similar to the bobbin 3 # 1 wound with an untwisted yarn, a state close to stationary can be maintained, and the yarn 2 unwound from the bobbin 3 # 1 is applied to the eyelet 25 as shown in FIG. During this time, the yarn receiving portion 94 does not hang down below the bobbin, and the yarn 2 coming out of the outlet guide 11 and reaching the outlet eyelet 12 is formed on the outer peripheral edge of the annular yarn guide portion 95 described above. Since the yarn path is pulled out while sliding, the yarn path is completely regulated.

Further, in the bobbin holder 93, a bobbin 3 # 1 wound with an untwisted yarn is inserted into the spindle 8 above the bobbin holder 93, or an empty bobbin 3 # 1 is inserted. In order to facilitate the work of removing the bobbin from the spindle 8, a space S having a length of at least approximately two thirds of the entire length of the bobbin wound with the untwisted yarn held by the bobbin support is formed. Things are desirable.

Therefore, by using the bobbin holder 93, it is not necessary to provide an extra space around each spindle 8, and the space between the spindles 8 can be narrowed. The overall size can be reduced, work efficiency can be greatly improved,
It is also possible to solve the above-mentioned problems of interference between unwound yarns unwound from adjacent spindles, occurrence of twist spots, and occurrence of thread cutting.

FIG. 9A shows the bobbin holder 93.
FIG. 9B shows an example of manufacturing a twisted yarn by rotating the left and right spindles 8 by a motor driving method using a motor. FIG. 9B shows an example in which the left and right spindles 8 are rotated by a belt driving method. It is an example in the case of producing a twisted yarn. In each case, each spindle unit 8
An appropriate tension applying means 96 such as a disc tensor, a ball tensor, a bar tensor, etc. can be arranged on the eyelet 25 at the tip of the eyelet.

FIG. 10 is a front view of FIGS. 9A and 9B. In the present invention, the bobbin support 1 described above is used.
The hollow shaft portion 22 of the spindle 0 and the spindle 8 is replaceable with a bobbin support and a hollow shaft portion having different shapes depending on the shape and type of the bobbins 3-1 and 3-2 wound with untwisted yarn to be used. It is also desirable that the width and shape of the thread receiving portion 94 be changed according to the type of thread used, the shape of the bobbin, and the like.

The untwisted yarn drawn from the bobbin, which is the creel 1 in the present invention, may be twisted and supplied by an apparatus for gathering and processing yarns such as a loom, a knitting machine, a netting machine, or the like. It can be used in connection with a device for winding and collecting yarns such as a warp machine, or it can be used by directly connecting to a yarn winding device such as a bobbin winder. Various specific examples of weaving using the creel according to the present invention will be described below. For the sake of simplicity, a description will be given of an example in which weaving is performed on a creel provided with a single twisting device using a needle narrow loom to fabricate two bands on the left and right. To explain an example in which the spindle is in a low rotation range, assuming that the loom rotation speed is 2000 picks / min, a weft driving speed of 33 picks / inch is about 1.5 m / min, and a 16.5 pick / inch weft. If the number of driving is about 3.0 m / min, a warp is supplied. If a yarn having a twist of 100 t / m is supplied to these woven fabrics, the rotation speed of the spindle in the creel of the double twisting system of the present invention is 75 rpm at a yarn speed of 1.5 m / min.
If the yarn speed is 0m / min, the rotation speed of 150rpm will be 1
A twist of 00 t / m is obtained.

In the present invention assuming a narrow fabric, the minimum spindle rotation speed is assumed to be 60 rpm. The use of the inventive creel of this type of ordinary fabric is described below. FIG.
In the case where each stage is controlled as a motor direct connection series, each stage will be described as an A stage at the top and an F stage at the bottom. 1) In FIG. 1, two stages of A and B are driven by a motor 6 # 1, and two stages of C and D, and two stages of E and F are respectively driven by a motor 6 # 2 and a motor 6 # 3. If the motors 6-1 to 6-3 are all in the same rotation direction and number of rotations, the twisting degree is the same and the left and right twisting directions are different from each other when viewed from the front of the creel. Will be. In this case, if necessary, the left and right woven fabrics having different twisting directions can be obtained by directly weaving the creel left and right yarns to the left and right looms.

2) By separating the Z twist and the S twist between the creel outlets and the tension roller group 12 and pulling them into the loom, the left and right two bands have a S / Z twist mixed at a predetermined width. Is obtained. If the woven fabric is cedar twill weave using the same direction of twist yarn, the appearance of the twill differs depending on the twill direction, but with this method the twist direction can be changed for each twill, so the appearance of the twill is the same Fabric can be woven. Those skilled in the art can arbitrarily perform the sorting method according to the specifications of the fabric.

3) When the rotation directions of the motors 6-1 and 6-3 are the same and the rotation direction of the motor 6-2 is rotated in the opposite direction, the Z twist and the S twist on both the left and right sides of the creel are equal to each other. Obtained step by step. The creel left and right yarns are pulled into the left and right two bands of the loom in that order and woven. When weaving relatively strong twisted yarn with unidirectional twisted yarn, twisting often occurs in the woven fabric, but the woven fabric woven in this way has a balanced Z and S twist, so it must be balanced and twisted There is no.

4) There is a case where it is desired to use warps having different thicknesses in the same woven fabric, or a case where it is desired to partially change the twist degree even when using yarns having the same thickness. In such a case, each of the motors 6-1 to 6-3 can be arbitrarily changed to set the required twist degree for each warp. If necessary, it is possible to supply untwisted yarn by stopping some motors.

5) If all the motors are stopped, only the untwisted yarn or the twisted yarn can be supplied as in the conventional creel. Although the case where the creel according to the present invention is used for a loom has been described above, the present invention is not limited to a loom, and the present invention can be used without difficulty for a creel to be supplied to a warping machine. In this case, since the supply speed is high, it is usually used in a high rotation range. An example of use in a high rotation range will be described using a needle narrow loom as an example.

For example, if the weaving machine is 2,000 picks / minute and the number of wefts to be driven is a blind-woven woven fabric with a weft density of 3 cm / 1 pick, weaving is performed at 60 m / minute. When a twist of 100 t / m is added to this warp, the spindle rotation is about 6000 revolutions / minute in a normal twisting apparatus,
In the case of the double twisting method, 3000 revolutions / minute may be used. When the predetermined device is a warping machine, if the double twisting method is used, the yarn is twisted at 3000 revolutions per minute and wound at 60 m / min. If the yarn is wound in minutes, a yarn having a twist of 150 t / m can be warped.

[0079]

Since the creel according to the present invention has the above-described structure, many effects as described below can be obtained. 1) Since the spindle rotation can be varied over a wide range, the twisting degree can be adjusted according to the winding speed of the loom or warping machine without being restricted by the winding speed, and the application range is greatly expanded.

2) According to the creel of the present invention, wasteful work due to the use of twisted yarns, for example, a work of twisting a twisting machine, a work of rewinding from a twisting bobbin, and the like can be omitted, so that the entire manufacturing time and cost are reduced. Productivity is improved. 3) Straight paper tube, tapered paper tube, aluminum pan, etc.
It can be used without having to change the commonly used yarn in the wound form.

4) When a twisted yarn twisted in advance is used, the weight (length) of the yarn wound on the bobbin is smaller than that of the large package yarn supplied from the original yarn manufacturer, but in the present invention, the large package yarn is used. Has the advantage that it can be used as it is. 5) Since the yarn is stationary and only the spindle rotates, 1
Many spindles can be rotated by one motor. In addition, a single spindle is provided with a pair of twisting mechanisms on the left and right sides, which contributes to a reduction in capital investment cost due to the simple configuration. 6) When using S / Z twisted yarn mixed with warp of woven fabric In addition, there is no danger of misplacement of the yarn. Also, SZ
The use of a mixture of twisted yarns makes it easy to prevent twisting of the product even as a strongly twisted yarn.

7) By using a plurality of drive trains, it is possible to easily give each of the yarns different in material and fineness an appropriate twist according to the use. 8) If the multifilament yarn is twisted relatively strongly, the yarn is twisted due to untwisting and the workability is deteriorated. Therefore, it is necessary to perform the twist preventing process with the conventional twisted yarn, but the present invention requires the twist preventing process. Workability is not impaired.

9) In the present invention, the yarn twisted to an arbitrary twist degree can be directly supplied to various fiber processing machinery, so that the effect of changing the twist degree can be confirmed while processing the texture of the product, and In addition, it is possible to manufacture a product having excellent quality without yarn roughness as compared with the case where a twisted yarn twisted in advance is used. 10) Twisted yarn by a twisting machine is generally known to have a lower yarn strength than the original yarn, but the twisted yarn according to the present invention hardly reduces the yarn strength.
