Disconnections occur frequently. In the prior art, processors for such yarns, especially various filament yarns, have significantly increased speed and become popular in recent years. For example, traditional yarn knitting machines called cable twisters are commonly used to knead two pieces of yarn. Silk yarn to make sewing thread. At present, the pirn applied to the twisting machine has a high weight of 3 kg (a wire length of about 180,000 meters) and has a large size. The maximum number of rotations of a twisting mandrel during operation is 9,000 rpm. Attempts have been made to increase the number of rotations of the torsion mandrel to 11,000 rpm to further increase productivity by using a weft tube of the same size. A simple description of a kneading mechanism for a conventional cable twisting machine will be described with reference to FIG. 5. A large-sized wire feed weft bobbin 7 is coaxially supported on a torsion mandrel 6, while a larger-sized wire feed is simultaneously formed. The weft feeding tube 丨 is supported on a creel (not shown). A first original thread Y1 introduced from the thread feed weft bobbin of the bobbin frame is fed into the torsion mandrel 6 at one time and then led to the outside and guided to a via a balloon guide 8 just above the torsion mandrel 6 ^ 1 ^ 1 Haunting Shao I 〇. At this time, the first original thread Y1 is rotated around the thread-feeding weft yarn 200407473 supported on the torsion mandrel 6 and guided to a balloon guide 9 at the same time, and u is reduced into a balloon. On the other hand, the second original thread Υ2 directly from one of the thread feeding weft tubes 7 supported on the torsion mandrel 6 is also guided to the winding section via the balloon guide 9 at the same time. Therefore, the first and the first The two original threads Υ1 and Υ2 are kneaded in the balloon guide 9 and a single strand Υ3 is wound around the winding portion 10. With a thread knitting machine having this kneading mechanism, in particular, when winding the first thread on the weft bobbin supported by the & support on the bobbin, the original thread is a full length (approximately 180,000 meters) In the case of uniform and high-quality yarns, the tension control can be performed with high accuracy. Alternatively, if the design of the internal and external structure of the mandrel and the peripheral attachments is changed, even if the twisted mandrel is rotated at a specific high speed of 9,000 rpm or higher, the kneading can be performed without special hindrance. However, it has the disadvantage that high-quality yarns also have a local fuzziness due to twisting during the thread feeding in the thread feeding guide of the first original yarn, or because of a twist during the yarn travel. A pile is formed. For this reason, when a defective portion is accidentally caught in a guide of a yarn travelling path ', a large torsional force will be generated between the guide and a line kneading spindle on the downstream side thereof. For this reason, the pulling force also affects a balloon, and the maximum diameter of the balloon becomes smaller than a preset allowable diameter and interferes with peripheral devices located around the lead-in and lead-out portions of the first original line sent to the torsion mandrel. . In this case, the line may be cut off at the same time as the interference effect, and this often happens. This situation is particularly likely to occur in the case where the first original thread is a multifilament yarn. In addition, when the tension is increased, the thread will immediately break due to various reasons. Therefore, 200407473 is similar to the conventionally known various tension adjustment devices or controllers. It was detected that Rally Well often enabled a control Shao Fen to operate but it was too late. Therefore, thread breakage cannot be prevented at all. Even when knitting high-quality yarns, this situation cannot be avoided by traditional control methods or design changes. One of the objects of the present invention is to provide a thread break prevention device capable of eliminating a situation as much as possible for high-speed operation. Another object of the present invention is to provide a typical yarn processing machine which can effectively apply the thread break prevention device. Type of wire gripper. Seeking the most effective device to achieve these goals and conducting many tests in many different ways, it was learned that even in the case of the first-line feed mechanism used for the first original line, abnormal tension caused by some of the aforementioned defects can still be introduced After the mandrel is twisted in one line, the occurrence of disconnection is prevented by avoiding the influence of the abnormal tension fluctuation on the first original line. In order to prevent the abnormal pulling force from reaching the first original line after the lead-in thread is combined with the mandrel, it is better to reduce the pull force by 爰, before the first-orientation line guide the line-to-thread mandrel, but if the tension fluctuation is detected And the pulling force is then slowed down as in the case of a normal pulling controller, a wire break may occur. In order to avoid this effect, it has always been necessary to comply with the fluctuation of the pulling force (especially an increased pulling force) and immediately before the lead-in thread and the mandrel Slow down the pull. In order to slow down the pulling force, it is further necessary to first determine the area where the spring-spindle mandrel m, which is located in the first-line feed section, generates a fluctuation in the pulling force, thereby determining the installation position of the slowing down member. According to various experiments, it is known that the tension fluctuations are caused by the fluff shape of the constituent fibers due to the pile or twisting. 200407473 Uneven hook 'and the cross-sectional shape of the constituent fibers of the yarn lead to a uniform (such as twist The yarn is caused by a local loop) caused by the thread or the thread feed mechanism to the thread feed mechanism. It has been found that 'when the original thread wound on the -thread feed weft tube is tangled due to uneven mouth load, an abnormal tensile force will be generated, making the original thread fail to smoothly lead out of the thread feed weft tube or the yarn configuration The uneven part will be stuck in a guide located in the middle of the yarn travel path without being pulled by ordinary pulling force. Based on this result, in any case, the device for slowing the pulling force is set at least on the torsion mandrel. The yarn travel path from the thread feed section to the lead-in section is sufficient. In addition, it is preferable to set the tension reduction device on the guide portion near the line feeding portion, by using a simple tensioner such as a traditional bounce or jumping roller or using a tension detection The detection signal of the device responds to a command sent from a control unit to increase the rotation speed of the feed roller and the conventional control device that over-feeds the yarn as a tension mitigation device, but still uses the method 70 to fully absorb large tension fluctuations, or The controller cannot keep up with the propagation time for the undulations of the pulling force to twist the mandrel. Therefore, the tension mitigation device is neither a tensioner similar to a conventional tensioner or a control device that simply absorbs torsion, nor is it a control device that increases the line feed after determining the tension fluctuation. A new type of mitigation device needs to be developed. After further investigation, the present invention was finally completed. More specifically, as described in the first aspect of the present invention, the basic structure of a wire break prevention device is characterized by including a wire break prevention device having a tension reduction unit 'the tension reduction unit is disposed on the travel of a yarn On the path and 200407473 can be used to reliably feed the yarn feed to a downstream side when the pulling force exceeds _. The preset pulling force corresponds to the yarn pulling force 7. An almost constant tension at a yarn such as a multi-strand yarn making machine is provided to a traveling yarn and is slightly fluctuated by the influence of the friction of the machine or the surrounding equipment. The fluctuation is very small, and the tension fluctuation can be eased. In a kneading machine or a thread kneading machine, vibrations or dynamic friction during the travel of a yarn are usually placed between a spring, a spring feed, and a processing unit. However, if there is no intervention as described above, the pull-down tensioner in the wire break prevention device according to the present invention completely absorbs and reduces the pull-down tensioner according to the present invention, and neither absorbs nor slows down the pull force The undulations are more suitable for large undulations than the slight undulations of the tension generated during the mid-line feed in the stationary state described above. For example, in a processor such as a wire kneading machine used to provide twist to the yarn while generating a balloon effect by the rotation of a torsion mandrel, the diameter of the balloon depends on the rotation speed of the torsion mandrel and the yarn weight. And yarn tension. In order to determine the diameter of the balloon within a predetermined range, it is necessary to set the rotation speed and yarn tension of the torsion mandrel to corresponding values in the case of similar yarns. Usually 'set the speed and then set the tension range of the yarn, and the yarn tension applied from the thread feed section to the thread kneading mandrel is adjusted by a spring tensioner or a ball tensioner, when the yarn tension becomes low At a set tension, the diameter of the balloon increases beyond a distance (installation space) between adjacent mandrels. The tension can be easily adjusted to be equal to or higher than the set tension by a tensioner. On the other hand, when the pulling force exceeds the set pulling force, the diameter of the balloon will decrease. If the diameter decreases, the yarn lead-out portion of the balloon will contact the peripheral tools, and specifically, -10- 200407473 'a multifilament yarn is cut immediately. In order to avoid this situation, it is necessary to reduce the tension of the yarn before a tension fluctuation occurs as described above and a tension fluctuation reaches the stir-in portion of the twisted mandrel. Therefore, in the mitigation unit according to the present invention, while generating a tension fluctuation exceeding a preset tension, a yarn is fed to the downstream side with a feeding amount corresponding to the tension fluctuation without fail by a time difference without fail. As a result, the undulation of the tension of the yarn is immediately alleviated on the downstream side of the alleviation device according to the present invention. For example, the yarn system that introduces the torsion mandrel maintains a normal set tension without affecting the formation of a balloon and maintains a predetermined balloon configuration, so that it can be smoothly blended without breaking. The second aspect of the present invention relates to a disconnection preventing device, wherein the tension reducing unit is a rotatable roller that rotates at a fixed rotation speed, and the rotatable roller system has a yarn feed amount increasing and decreasing portion to correspond to the yarn. Increased and decreased yarn behavior immediately increases and decreases yarn feed. When the tension of the yarn is increased, the yarn will be tightened, and when the tension is decreased, the yarn will be relaxed. In the present invention, a behavior that depends on the fluctuation of the tension of the yarn is used, and a rotatable roller driven and rotated at a fixed speed is used as the tension reduction unit. In addition, the rotatable roller system includes a yarn feed amount increase and decrease portion. For example, a spring may be used as the yarn feed amount increase and decrease portion. The spring uses an elastic material with a peripheral surface of the roller and is based on the yarn. Tension fluctuations change the amount of yarn strength and pressure contact. By changing the pressure contact amount, the amount of yarn slip caused by the peripheral surface of the roller contacting the peripheral surface of the rotatable roller can be fluctuated, so the pressure contact amount is used to change the yarn feed amount. The third aspect of the present invention relates to a thread breakage prevention device, wherein the yarn feed amount -11-200407473 further includes a mechanism for pulling out the yarn with respect to the ups and downs when the yarn tension is generated and immediately pulling the yarn. The yarn acquisition and feed structure is fed to one of the draw sides by the required feed amount. In the case where the peripheral surface of the rotatable roller carries the yarn with a specific fillet, the contact force to the peripheral surface of the roller is increased, so that when the yarn 2 = south, the yarn tries to be centered as described above. Move in the direction. For example — ** 'grooves used as the yarn acquisition and feed structure are formed in the circumferential direction of the peripheral surface of the rotatable roller, and a groove with v = cross section is formed along a bottom surface. An elastic layer of ideal thickness is formed above the surface of the groove-like two-body body, and a rib-like bulge 2 suspended in the M groove is formed from the ridge of the intersection between the ϋ-shaped section and the v-shaped section 2 of the groove. In the case of =, the bulge should preferably have a nearly triangular cross section, this triangle; the surface is such that the extended surface of the bottom surface of the U-shaped groove or the mouth-shaped portion of the elastic layer is located on one side. If the tension of the yarn carried on the peripheral surface of the rotatable roller and traveled with the rotation of the roller is at a predetermined tensile fiber, the yarn contacts the periphery of the roller by a pressure contact force corresponding to the tensile force Surface bonding:-The yarn is fed to the downstream side by a predetermined feed amount. When the pulling force becomes more than the preset tension, the pressure contact force acting on the center of the roll applied to the yarn will overcome the supporting force of the bulge of the elastic layer, causing the bulge to elastically deform and thus lead to the V groove. The groove portion is strongly held in the bottom of the V groove portion. ®Λ ′ uses the rotation of the rotatable roller to reliably take up the yarn on the upstream side and feed it reliably to the downstream side. As a result, the tensile force is abnormal; the yarn is not transmitted to the yarn introduction portion of the twisted mandrel, and the yarn is not cut, for example. -12- 200407473 The fourth aspect of the present invention relates to a seed yarn processing machine, which includes a yarn feed section and a yarn processing section and has any one of the first to third forms according to the present invention. Between the feeding unit and the yarn processing unit-a thread breakage prevention device on the yarn travel path. Examples of yarn processing machines include manufacturing machines and thread kneading machines for finished yarn bulk products and various multi-yarn finished products. In particular, the fifth type of this specification defines a thread kneading machine that is a typical yarn processing machine. Turn on the machine. The fifth aspect of the present invention has a secret-type thread kneader, which has thread break prevention on the yarn travel path provided between the thread feeding portion and the torsion mandrel according to the first to third aspects of the present invention. The device 'and further includes a feed roller' This feed roller is disposed between the torsion mandrel and a strand winding portion and can be used to over-feed a strand to the strand winding portion. In the thread knitting machine, 'the yarn rotates around the mandrel and at the same time forms a balloon between the yarn introduction part of the torsion mandrel and the balloon guide just above the same mandrel' and is twisted in the balloon guide so it is rolled Wind around the winding section. In general, the yarn is pulled out of the torsion mandrel by the winding tension of the winding part. At this time, the yarn tension is applied to the balloon by the centrifugal force of the yarn. The line length becomes smaller than the original line obtained before the balloon guide. Therefore, the yarn pulling force becomes higher than the preset winding pulling force. In the present invention, in addition to the disconnection preventing device, a feed roller for overfeeding is provided between the torsion mandrel and the strand winding shaft.

Therefore, ‘Dang Xing: When the pulling force acts on the original thread, the yarn fed to the twisted mandrel is also set to a winding speed of at least a large reel winding portion to ensure a stable balloon effect. Embodiments: A preferred embodiment of the present invention is described in detail with reference to the drawings. FIG. 丨 schematically shows a wire kneading step of a wire kneader called a cable twister, which includes a wire kneader according to the present invention. One of the first embodiments is a disconnection preventing device. The number 1 shown by 囷 represents a thread car, which is located above a frame, from the top, the spring, the il, the seven, the 聿, the y, and the tube. 'A large number of thread feed weft bobbins 1 are set on the spool frame. A vertical acquisition method is used to draw a first original yarn Y1 (yarn) composed of a multifilament. In this embodiment, the thread feed weft tube 1 has a heavy weight of 3 kg (about 180,000 meters of thread). Length) and large sizes. The first original thread Y1 outside the weft feed tube 1 is fed through a spring tensioning device 2 into the disconnection preventing devices 3 and 4 according to the present invention, passes through the disconnection preventing devices 3 and 4 and starts from a twisting center. One of the mandrels of the shaft 6 and one of the yarn introduction ports -14- 200407473 (not shown) are introduced into the cans through a ball tensioner 5 and lead out a line formed in the side of the mandrels of the cans 6a Outside the port and outside. The mandrel can is shaped as a cone and a second thread feed weft ν f 7 for the second original thread γ2 (yarn) is fitted into the tank 6a from above. The thread feed weft tube 7 has a lighter weight than the first green feed weft tube 1 and is generally provided with a small overall thread length. A balloon guide 8 is provided just above the second thread feed weft tube 7 and a first original thread γ 丨 drawn from the side of the mandrel can 6a is inserted through the balloon guide 8. On the other hand, the first original thread γ2 wound around the second thread feeding weft tube 7 fitted in the middle of the mandrel can is directly inserted into the balloon guide $ along with the first original thread γ 丨. When the twisted mandrel 6 rotates, the first original thread γι rotates around the second thread feeding weft yarn 7 while forming a balloon between the yarn lead-out port of the mandrel can and the balloon guide 8, and the balloon guide 8 In the 8 part, two original threads T1 & T2 are rolled into one. A strand γ 3 thus obtained is excessively supplied to a winding shaft 10 through a feed roller 9 and wound on a paper tube (plastic tube, aluminum tube) through a winding portion 10 to form a flat top circle. Head 11. This embodiment is characterized by the disconnection preventing devices 3 and 4 and the feed roller 9 as a tension mitigation unit. FIG. 2 shows a schematic structure of the disconnection preventing devices 3 and 4 and the disconnection preventing devices 3 and 4 and the feed An enlarged view of an example of the related structure of the roller 9. The disconnection preventing device according to this embodiment is composed of a rotatable roller 3 and a guide roller 4 which simply rotates freely as shown in Figs. As shown in FIG. 3, the rotatable roller 3 has a first groove portion 3a and a second groove portion 3b. The first groove portion 3a has a near U shape formed on a peripheral surface thereof in a circumferential direction. In the cross section, the second groove portion has a v-shaped cross section formed at -15-200407473 along the bottom of the first groove portion 3a in the same circumferential direction. The amine base rubber or silicone rubber having a predetermined hardness J: Furthermore, a first elastic layer 3c is formed in the first groove portion: a material made of a material.廿 ft and the second groove part 3b are integrally two "and, on one side, occupy the extension surface of the bottom surface of the -th groove part /, the bulge 3d with a rectangular cross section is connected with the elastic bank_ 一 沟The groove part 3a and the second groove part 3b are prepared. * The middle end points of the respective extensions of c are opposite. The first eyebrows of m, the first eyebrows of m, which are fed by the spring tensioner 2 when the opposite ridges are close to each other. The line Y1 passes almost through the lower half of the rotatable roller 3 with the upper structure, and will; 4 min, box t… the rear tooth-like shape passes through the upper half or more of the peripheral surface of the sub 4 And sent to the ball ^ tensioner 5 'located below, and then introduced the torsional palpitations through the ball tensioner 5. The tension in the first original line Y1 statically fluctuates ^ ^, yr 罘 an original line Y1 by especially The pressure contact force due to the fluctuation of the supporting force is supported on the elastic layer of the first groove portion 3a of the rotatable roller 3 and sent to the downstream side, and at the same time, the degree of slippage is changed in accordance with the pressure force. The first original line γι on the tube, for example, has a fluff and tangles with adjacent original lines without being normally pulled by a tension Draw out in turn “then-pulling force quickly between the one-line feed portion and the rotatable roller 3 according to this embodiment” also by rapidly increasing the pulling force so as to resist the first-original line that can be obtained from the peripheral surface of the rotor 3 γι increases. When the pressure contact force exceeds the supporting force of the < protrusion 郅 3d in the bottom of the first groove portion 3a formed on the peripheral surface of the rotatable roller 3, the protuberance of the protuberance 3 (1 is tied to one The roller is elastically deformed in the center direction, so that the first original line γ1 slides into the second groove portion 3b having a v-shaped cross section. -16-200407473 As a result, the first original line Y1 is strongly held by the second groove portion 3b. And immediately release the tangling effect of the first original thread γ 1 in the weft bobbin 1 by the rotational force, and the first original thread Υ 1 is reliably sent to the downstream side. Therefore, the abnormal tensile force is not transmitted to the torsion on the downstream side. The yarn introduction part of the mandrel 6 can prevent a balloon diameter from being reduced due to abnormal pulling force, and can reliably prevent thread breakage. The entanglement effect of the first original thread Υ1 is released as described above, and at the same time, the first original The pulling force of the coil 1 immediately returns to a stationary state. Therefore, the first original line is guided by the bulging portion 3d to generate tension only by the static state tension, and automatically returns to the elastic layer surface of the first groove portion 3a again. In other words, according to this embodiment, The rotary roller contacts the yarn by pressure, and increases the pressure contact force of the yarn with respect to the peripheral surface of the rotatable roller when the yarn pulling force exceeds a predetermined value by holding the yarn. In order to excessively feed the strand Y3, the rotation speed of the feed roller 9 located between the balloon guide 8 and the winding section 10 is slightly higher than the winding speed of the winding section 10. Generally, the winding section 1 The winding tension of 〇 is increased by more than a set winding tension due to the contraction caused by the rolling of the first original line Y1 balloon and the tension is increased. Therefore, the flat top round head 丨 is wound into a hard shape. In order to avoid this situation, the yarn is over-fed by the feed roller 9 to reduce the tension of the yarn fed to the winding section (H), so a flat top round head with a set winding hardness is manufactured. 11. In this case, in her example, the feed liquid 9 and the rotatable race between the balloon guide 8 and the coiling unit 10 and the spinner, will be early, and the turn 3 will be a branch. On the same rotation axis 12 as above, and the feed roller 9 and the rotatable Han, "conductor 3 has the same rolling structure in terms of structure and size, rollers 3+ and 9 both have Rotate at the same speed. With -17- 200407473 this structure, when the abnormal tension state is triggered, the feed amount of the first-original wires of the rotatable roller 3 is approximately the winding amount of the strand Υ3. As a result, it is possible to avoid an increase in the pulling force for the balloon formed by twisting the mandrel 6. Fig. 4 schematically shows a second embodiment of the disconnection preventing device according to the present invention. According to this embodiment, the disconnection preventing device serving as a tension mitigation unit is constituted by a rotatable roller 3 and a guide roller 4 and a leaf spring 13 having the same structure as the first embodiment. 'In this embodiment, The plate spring-like arrangement of the guide rollers 4 can make the first line of the original line Chuanxiong, which is drawn from the line feed section of the -not shown, during the static operation as shown in the solid line of Fig. 4, and then easily contacted. Rotary roller 3. More specifically, the first-original wires drawn from the wire feed section are first inserted through the insertion hole 13a formed on the free end of the leaf spring 13 and passed through the guide roller 4 almost horizontally and then down ... In the static tension state, the peripheral surface of the rotatable roller 3 simply contacts the first original lines that linearly travel from the leaf spring 13 to the guide roller 4 without reliably transmitting the original line γι. When a tension undulation is caused within this range so that no disconnection occurs on the first original line γι and, in particular, a larger pulling force than the static pulling force is generated, the first original line is tight and the leaf spring 13 corresponds to the increase of the pulling force 13 The universal elastic deformation shown by the arrow in FIG. 4 causes the first original line Yi traveling between the leaf spring 13 and the guide roller 4 to contact the peripheral surface of the rotatable roller driven and rotated. The first contact line ¥ 1 is surely fed to the downstream side using the pressure contact force, and at the same time, a slip amount fluctuation is caused above the peripheral surface of the rotatable roller 3 in the same manner as in the first embodiment. When some defects occur on the wire feed part, the first original line γι is further increased. • 18- 200407473 Overtime, the plate springs yellow 1 3 Large elastic deformation. The first original, spring γ 1 can be pushed against the contact surface by pressure contact force. Rotate the peripheral surface of the roller 3 and slide the first original line η into the ν-shaped groove portion shown in FIG. 3, so the holding force for the original line y is plus and the lead-out side of the line is strongly pulled out. The original line γ 丨 is used to eliminate this defect. At the same time, the original line γ is surely fed to the downstream side at a feed amount corresponding to one of the rotation speeds of the rotatable roller 3 driven and rotated. Therefore, the defect of the first original line Υ1 is eliminated, and at the same time, the first original line γm is restored to have a static tension. Therefore, the first original wire γι is pulled out of the v-shaped groove portion 3b on the peripheral surface of the rotatable roller 3 by the elastic force of the leaf spring 3 and returns to this stationary state to contact the periphery of the rotatable roller 3 This operation is performed at the same time at the same time. Therefore, the abnormal tensile force generated in the first original line Y1 on the side of the thread feed portion is not transmitted to a yarn processing portion such as a torsion mandrel (not shown) on the downstream side. Can reliably prevent disconnection. Although the structure of the rotatable roller 3 has been described above by using an example of the peripheral surface of FIG. 3, the structure of the roller is not limited to the illustrated example and various changes can be made. In short, it can be based on contact with the peripheral surface. The tension of the yarns fluctuates to change the actual feed. In addition, when such an abnormal torque that may cause thread breakage is generated in the processing section, it is preferable to use a feed amount that can reliably feed the yarn in accordance with the excessive feed amount of the feed roller in the winding section. The structure. Table 1 shows a line because a cable twister having a disconnection preventing device (tensile mitigation unit) according to the present invention shown in FIG. 1 and a first original wire γ 1 of the conventional cable twister shown in FIG. 5 are used. The result of the state of disconnection due to the fluctuation of feed tension. Incidentally, the weft tube cover member represents a tubular cover member for covering a portion around the second thread feed weft tube 7. -19- 200407473 Table 1 Mouth σ First and early 7G: Gravity reduction weft bobbin T-0 Τ-1 Τ-2 Τ-3 Broken wire 0 0 0.2 6 3 4 10 Soil 2 15 Soil 1 6-7 9.5- 9.8 20 ± 5 28 ± 2 10 14 30 soil 5 40 soil 5 13.8-14.3 21-22 40 soil 10 45 soil 10 17-22 28-32 _ miscellaneous 70- yes X 〇0.2 6-7 11 40 soil 10 one : _ 70- is known from Table 1 "", the traditional cable twister does not include the wire break prevention device according to the present invention, m.
