The prior art has seen the disclosure of various fiber bundle winding devices to help achieve an improvement in line quality, such as winding a drawn fiber bundle before the fiber bundle is applied for ignition, to reduce fluff. The production of etc. The basic function of these devices is usually the use of an endless belt (perforated skirt) for the winding and transport of the fiber bundle. For example, in Japanese Patent No. 11-2868 3 (hereinafter referred to as the first patent), the ones disclosed in paragraphs 0022, 0 03 0, and 1 and 7 are included. In addition, Japanese Patent Publication No. 2000-34631 (hereinafter referred to as the second patent) is also disclosed in paragraphs 18 and 1 of the accompanying drawings. In addition, the German Patent Document D E 1 9 7 0 8 4 1 0 A 1 (hereinafter referred to as the third patent case) is also disclosed. When the perforated belt covers the suction hole extending in the direction in which the fiber bundle moves, it moves. In order to adjust the movement of the perforated belt in the width direction (ie, the lateral movement), according to the disclosure of the first patent, a tension element made of plastic is provided to achieve the tension applied to the perforated belt. It refers to the purpose of the guide -6 - 1252878. Further, the first patent further provides a lateral guide for engaging the perforated belt to a hollow outer body (h ο 11 〇 W profile) having a suction hole. The second patent discloses the manner in which the perforated belt is guided in the lateral direction, and the follow-up is used as a guide for the transverse end of the tension roller which is tensioned to the perforated belt.

The conveying roller 7 2 a is rotatable by friction with a friction roller portion 75 5 a of one of the rotating shafts 7 5 , wherein the rotating shaft is disposed parallel to a front bottom roller (not shown). The lateral movement of the perforated skirt 7 1 can be adjusted by one side of the friction roller portion 7 5 a . The spinning machine is equipped with the above-mentioned fiber bundle winding device, which is used for producing a yarn (t li read, or wire) by spinning, and is not equipped with a fiber bundle winding device, and is spun through a spinning machine. The production of yarns, the former can reduce the production of fluff 'can also reduce the production of thread specks', thus increasing U%. However, such devices of the conventional technology still require further improvement in the conventional fiber bundle winding device, and there is no special design plan for the downstream of the pinch point, so that the quality of the wire can be improved. Therefore, the inventor of the present invention provides a fiber bundle winding device capable of improving the quality of the wire, and is provided with a suction pipe which is also located on the downstream side of the clamp point. The suction pipe system 1252878 is passed through a breathable skirt (perforation protection). The skirt applies the suction action to the fiber bundle; and is provided with a crimping member also located on the downstream side of the jaw point, the crimping member having a breathable skirt for wrapping the crimping member , 俾 increase a velvet angle. In this case, it is still necessary to prevent lateral displacement of the breathable skirt.

The breathable skirt must be updated during each processing cycle of a certain period of time, or when the service life has reached the end of its useful life. In the configuration in which the adjusting member is disposed in addition to the suction tube and the crimping member, the renewal of the breathable protective skirt is extremely complicated. 'This is due to the replacement of the breathable protective skirt, and the adjustment member must be unwound. The connection 'and the typical' a spinning machine There are hundreds to thousands of breathable skirts, and the time required to replace them will be extremely amazing. In addition, the third patent discloses a processing for the rotating shaft, but this will SUMMARY OF THE INVENTION The object of the present invention is to provide a fiber bundle winding device for a spinning machine which can suppress the generation of fluff as compared with conventional techniques, thereby improving the quality of the line 1252878.

Note that in this embodiment In 1252878, the support member 36 is integrally formed with the support member of the front top roller 19. On the other hand, on the bottom side of the fiber bundle winding device 3, the roller frame 15 of the drafting device 1 1 Half of the allocation The spindle, that is, the four spindles in the present embodiment, is configured as a group of units. As shown in Fig. 3, the roller frames 15 are arranged at predetermined intervals in the longitudinal direction of the machine base. In the middle position, a support arm 3 8 is provided, and the state of the configuration is 'where the seat end (bottom end) is supported by the support beam 3 7 in the longitudinal direction of the frame. 3 5 is a supporter between the roller frame 15 and the support arm 38. As shown in Fig. 4B, the pre-formed length ' of the rotating shaft 35 corresponds to a plurality (four in this embodiment) The spindle, and the bearing 3 9 is attached to either end of the rotating shaft. Further, as shown in Fig. 1, the rotating shaft 35 is attached to the unit in a state in which the bearing 39 is coupled to the pair of end plugs 40. The support state of the suction tube 3 2 and the crimping member 3 3 is also such that the end portions thereof are mated with a pair of end plugs 40 for supporting the rotating shaft 35. As shown in Fig. 4A, the end plug 40 is supported in the engaging portion 40a by the supporting portions 15a and 38a provided on the roller frame 15 and the supporting arm 38, and therefore, The rotating shaft 35 is rotatably supported between the roller frame 15 and the support arm 38. The formed support portions 1 5 a and 3 8 a can support the two end plugs 40 ′′ and can support the end plugs 40 θ supported on the ends adjacent to the rotating shafts 35 . 5a is formed by a block (bI〇ck) fixed to the roller frame 5 and has a connecting recess, which is inclined upward on the front side of the frame for extension I252878 ° support portion 3 8 a It has a connecting recess, which is also extended on the front side of the base. If so, the end plug 40 having an engaging portion 4〇a, that is, engaging with the two notches, and only a simple press-fitting can be used to connect the support portion 1 5 a with 3 8 a is connected to the interface 4 0 a. The movable shaft 35 has a gear 41, which is arranged to be rotatable with the rotating shaft 35-5. The gear 4 1 is disposed at a position displaced by the center of the rotating shaft 35 toward the end side by the length of the spindle unit. As shown in FIG. 3, the front bottom roller $1 2 has a gear portion i 2 a formed at a position opposite to the gear 4 ° and engaged with the gear portion 12a and one of the intermediate gears 43 of the gear 41, The support arm 4 2 is rotatably supported, and the bottom of the support arm 42 is fixed to the support beam 3 7, which is the same as the support arm 38. That is, the torque of the front bottom tweezer 12 is transmitted to the rotating shaft 35 by the gear portion 1 2 a, the intermediate gear 43 and the gear 4 1 . As shown in Fig. 2, in the frame of the spinning machine, the arrangement of the plurality of conduits 44 for the fiber bundle winding device 3 and the suction source (negative pressure source) is in the longitudinal direction ( Extending perpendicular to the plane shown in Figure 2). The suction means 4 5 for maintaining a negative pressure in each of the conduits 4 4 are connected to the respective conduits 44 via a plurality of conduits 46. The one used as the suction device 45 is a fan motor 'where the fan 47 7 is driven by the motor 47. As shown in Fig. 2, the ducts 44 are disposed on the rear side of the drafting device 丨1, and the suction devices 45 are disposed below the ducts 44. The suction pipe 32 has a connecting portion 3 2 c (shown in FIG. 1 ) formed at a central portion of the longitudinal length, and the suction pipe is connected to the conduit 44 via a connecting pipe 48 , and the connecting pipe 48 is matched with the connecting portion 32 c . The connection is made parallel to the conduit 4 4 for extension. 1252878 Suction tube 3 2 has a sliding surface for guiding surface 3 2 b 'Sliding surface 3 2 b is provided with a plurality of suction holes 32a for sucking cracks. For fiber bundle F (velvet) against bottom jaw roller 3 5 a In terms of the direction of movement of the jaw points, the suction holes extend toward the upstream side. The suction tube 32 is formed in a manner that guides the breathable skirt 3 4 to bring it to the vicinity of the jaw points of both the front bottom roller 1 2 and the front top roller 19. As shown in Figs. 1 and 3, similarly, one of the adjustment guides 4 for preventing the lateral displacement of the breathable skirt 34 is integrally formed with the suction tube 32. The guide member 49 is formed by removing an upper stage portion 50 and a portion of the width of the breathable protective skirt 34, and the stage portion 50 is formed on the front side of the top of the suction tube 32. (For the moving direction of the fiber bundle F, it is located on the downstream side), so it extends in the longitudinal direction. Note that, as shown in Fig. 1, the ventable skirts exemplified are continued to be illustrated, facilitating the description of the suction holes 32a and the adjustment guides 49. In order to facilitate the manufacture of the suction tube 3 2 in which the adjustment guide member 4 is formed, the suction tube 32 is molded by extrusion, so that the stage portion 50 can be provided, and the suction tube 3 2 having the adjustment guide member 49 can be formed. In this part, the height is established as a result of the removal of the upper portion of the width of the breathable skirt 34, and the opening of the suction hole 3 2 a can be performed. The crimping member 3 3 has a sliding surface 33 n as a guiding surface for guiding the ventable skirt 34 for sliding. The folding member 33 is disposed in such a manner that the jaw point and the fiber bundle F are separated from the gas permeable skirt 34 on the downstream side of the jaw point, and the distance L between the two is shown in Fig. 6A. Not less than 5 mm 'and preferably 8 to 1 Omm. The crimping member 3 3 is formed in a rod-shaped solid member shape 1252878. Because the ventilating skirt 3 4 is made into a roll, it can be partially in contact with the suction pipe 3 2 , partially in contact with the winding member 3 3 , and partially in contact with the bottom jaw roller 35 5 a. And when the bottom jaw roller 3 5 & rotates and rolls on the sliding surfaces 3 2 b and 3 3 a , it is also a rotator. The breathable skirt 34 in this embodiment is made of a woven fabric to ensure proper gas permeability. As shown in the figures 2, 4 A ', etc., the vicinity of the lower portion of the winding member 3 3 is the front end portion of the suction nozzle 5 1 of a single type pneumatic device, when the fiber bundle F is composed of the drafting device 1 1 After sending out 'If a thread break (threadbrakd 〇ci η) is used, 'can be used to absorb the fiber bundle F. One of the base ends of the nozzles 5 1 is connected to one of the pneumatic conduits 52 shared by all the spindles. Next, the operation of the above-described apparatus will be described. When the spinning machine is operated, each of the fiber bundles F passes between the bottom rollers 2 to 14 and the top rollers 19 to 21 and the like, and is then guided to the fiber bundle winding device 30. The rotation speed of the top jaw roller 3 1 a of the conveying portion 31 is higher than the rotation speed of each of the front bottom roller 12 and the front top roller 19, and is passed through the conveying portion 3 1 under appropriate tension. After the pinch, the fiber bundle F moves toward the downstream side while receiving the twisting action. Moreover, the suction function of the conduit 44 is applied to the suction pipe 32 by the connecting pipe 48, and the suction surface 3 2 b forms the suction function of the suction holes 3 2 a, and is applied to the fiber through the gas permeable skirt 3 4 . Bunch F. Thereafter, the fiber bundle F is kept moving and sucked and wound (bundled) toward the position corresponding to the suction holes 32a. Therefore, the present invention can suppress the generation of fluff and the waste of cotton material, and improve the quality of the yarn, compared to the spinning machine not equipped with the fiber bundle winding device 30.

As shown in Fig. 6A, since the position of the crimping member is disposed on the downstream side of the suction pipe 3 2 and is separated from the suction pipe, the velvet angle Θ 1 is larger than that of the unfolding member 3 3 . The velvet angle Θ 2 at time (Fig. 6B). When the velvet angle is large, the distance of the cover contained by the fiber bundle F after passing through the pinch point until it is separated by the surface of the gas permeable skirt 34 is considerably long. Therefore, 'because the twisting action is applied to the fiber bundle F from the beginning, the fiber bundle will be rotated, and the fiber f protruding from the outer periphery of the fiber bundle F is in contact with the breathable skirt 34. Therefore, the fiber f is easily entangled in the fiber bundle F' and thus suppresses generation of fluff. Further, in the structure having the crimping member 3 3, when the fiber bundle F rolls on the skirt, it is reciprocating, so that the fiber f protruding from the outer periphery of the fiber bundle F is easily broken into the fiber bundle F.

The traditional concept holds that increasing the velvet angle may lead to the disconnection. However, when the fiber bundle winding device 30 is provided, since the fiber bundle F is taken out by the clamp point, it is wound by the suction action of the suction hole 3 2a, and therefore, due to the take-up action. The twisting is easy to reach near the pinch point, so the strength of the wire can be increased, so even if the velvet angle is increased, the increase of the wire breakage can be suppressed. Therefore, it is possible to suppress the concern that the capacity is lowered due to disconnection. The breathable skirt 34 for transporting the fiber bundle F is prevented from moving laterally by the action of the adjustment guide 49 when it is moved (rotated), so that the fiber bundle F can be moved in a stable state. The adjusting guide 4 for adjusting the ventable skirt 34 in a position (this position is close to the connecting portion 3 2 c to be connected to the connecting pipe 48) is used by the 16- 1252878 The end face (the phase portion 50 is removed along the end face) adjusts the movement of the breathable skirt 34 to either side. As for the adjustment guide: the adjustment guide 4' of the breathable skirt 3 4 which is folded around the end plug 40 is adjusted for the movement of the breathable skirt 34 toward the center of the suction tube 3 2 ' It is realized by adjusting one end surface of the guiding member 49 (the phase portion 50 is removed along the end surface), and therefore, the movement of the air permeable skirt toward the end side is adjusted by the end 4 4 0 0 One of the end faces is for it. This embodiment has the following effects: (1) For the moving direction of the fiber bundle F, the suction pipe is provided on the upstream side of the pinch point of the conveying portion 31. With respect to the moving direction of the fiber bundle F, the crimping member 3 3 surrounding a portion of the gas permeable skirt 34 is tied to the downstream side and parallel to the suction pipe 32. Therefore, the velvet angle can be increased, and the effect of suppressing generation of fluff can be increased as compared with the structure in which the crimping member 33 is not provided, so that the quality of the wire can be improved. (2) The adjustment guide 49 for preventing the lateral displacement of the breathable skirt 34 is formed integrally with the suction tube 32, and accordingly, the movement (rotation) of the breathable skirt 34 for transporting the fiber bundle F is caused by The action of the guide member 49 is adjusted to prevent lateral displacement. As a result, the fiber bundle F is moved in a steady state. Further, the integrally formed structure is simplified from the configuration in which the regulating guide and the suction pipe 32 are separated. (3) The suction pipe 3 2 in which the adjustment (section) guide member 49 is to be formed is formed by extrusion molding, and may have a stage portion 50, so the suction pipe 3 2 is intended to form a portion of the adjustment guide member. In the case of the establishment of the system. The adjustment guide member 49 is formed by removing one part of the phase portion 50 and is matched with the width of 1252878 of the breathable skirt 34, so that the manufacturing process is superior to welding, adhesion, or screwing. The way the piece is attached to the suction tube. (4) The crimping member 3 3 is provided in such a manner that the clamping point of the conveying portion 31 and the position "two" of the air permeable skirt 34 on the downstream side of the fiber bundle F from the jaw point are Not less than 5 mm. Therefore, when the fiber bundle F is moved while rolling on the gas permeable skirt 34, the protruding fibers f of the fiber bundle F are easily caught in the fiber bundle F, thereby achieving the effect of improving the generation of the pile. (5) The crimping member 3 3 is formed by a rod-shaped solid member. Compared with the crimping members formed by the tubular shape (hollow), it is advantageous for production. Moreover, it is not easily damaged if it is subjected to collisions during installation, disassembly, and maintenance work of other components. (6) The force of the top jaw roller 3 la to pressurize the breathable skirt 34 is derived from the bottom jaw roller 3 5 a, and the pressure applied by the top jaw roller 3 1 a is not imposed Since the tube 3 2 is sucked, the suction tube 32 can have a smaller rigidity than the conventional device, so that the suction tube 32 is made of resin, and its strength is more than sufficient. (7) The conduit 44 for maintaining the negative pressure source is provided separately from the pneumatic device. 'For the velvet to be sent out from the drafting portion, if it is broken, it can be sucked, then the suction pressure of the suction pipe 3 2 is It can be easily adjusted to an appropriate pressure. However, the present invention is not limited to the configuration of the above embodiment only, and may be of the following construction. It is sufficient to form the adjustment guide member 49 in at least one of the suction tube 3 2 and the crimping member 33. For example, as shown in Fig. 7, a configuration may also be employed in which the adjustment guide member 49 is formed in In the crimping member 3 3 . In the case where the adjustment guide 18-1252878 guide member 49 is formed in the condition of the crimping member, and the condition that the adjustment guide member is formed on the upstream side of the suction tube 32, the adjustment guide member and the accumulating guide member are already present. The ash is removed/removed from the ventilated skirt, and the former is superior. The adjustment guide 49 can be formed in both the suction tube 3 2 and the crimping member 33. In addition to forming the crimp member with a solid member, a tubular member can also be used. In the case of a tubular shape, the weight of the crimping member 33 can be light. Regarding the pinching point of the conveying portion, and the position at which the fiber bundle F leaves the gas permeable skirt 34 on the downstream side of the pinching point of the conveying portion 3 1 , the distance L between the two, as long as the distance L is not less than 5 mm, That is enough to suppress the production of fluff. There is no special limit for distance l. However, if the distance L is too long, it is not possible to greatly improve the effect of suppressing the generation of fluff, and instead increases the size of the stand, so the range is preferably in the range of 8 to 1 Omm. The structure of the conveying portion of the fiber bundle winding device 30 is not limited to the manner of installing a pair of jaw rollers, and may be, for example, another configuration for driving the breathable skirt 34, wherein the removal is omitted. The suction pipe 3 2 and the bottom jaw roller 35 5 a are provided, and a suction pipe having a suction hole formed at a predetermined position in an egg shape is provided, and the gas permeable skirt 34 is slidably surrounds the suction pipe. And the outer circumference of the crimping member 3 3 is wound, so that the top jaw roller is driven positively, and the breathable skirt 3 4 can be driven by the top jaw roller 3 1 a and kept ventilated The skirt 3 4 is pressed against the contact. In this case, the tension adjusting function for the breathable skirt 34 can be imparted to the crimping member 33. The suction function applied to the fiber bundle F conveyed by the breathable skirt 34 can also be applied to the crimping member 33. For example, in addition to forming the crimping member 3 3 by means of a tube member, the crimping member 3 3 may be provided with a plurality of 1252878 holes. In this case, the fiber bundle F is moved on the one hand while being sucked on the one hand and wound at the corresponding suction hole. If it is sucked, the fiber bundle is moved while being wound up, that is, even when passing through the pinch point, thereby suppressing the generation of fluff and the cost of the cotton material, thereby improving the quality of the wire.

The suction pipe 3 2, the winding member 3 3, the rotating shaft 35, and the like are not limited to the configuration in which four spindle units are configured as one unit, and the spindle unit adjacent to the roller frame 15 may be used. The number (for example, 8 spindle units) is configured as one unit unit, or two spindle units are used to form one unit unit. Moreover, it is not always necessary for all the units to have the same number of spindles, and the number of spindle units of the adjacent roller frames may be different from each other (for example, 6 and 2) to form two different units. group. The ends of the suction tube can also be closed. In this case, it is not necessary to seal the end plugs 40 at both ends of the suction pipe 3 2 , and only one connecting hole is needed for engaging the bearing 39 and the plurality of connecting portions (engagement holes) It is used to connect the two ends of the suction pipe 32 and the crimping member 33, which will greatly benefit the manufacture.

In addition to extending in the longitudinal direction and providing a plurality of conduits 4 4 , it is also possible to include the entire length of the cover spinning machine base and only one conduit. The position of the duct 44 is not limited to the one of the rear side and the upper side of the drafting device 1 1 , and may be disposed at the rear side or the rear side and the lower side of the drafting device 1 1 .

In addition to the configuration in which the conduits 14 are distributed by the suction tubes 32 provided on the left and right sides of the spinning machine, another configuration may be adopted, which may be respectively at the left and right sides, depending on the spinning machine. The longitudinal direction of the base is extended and the -20- 1252878 is placed in the left and right rows. In addition to the woven fabric to form a breathable skirt 3 4, it can also be made of knitted fibers. In this case, the gas permeability can also reach a considerable level, which can avoid the trouble of hitting a large number of small holes in a 'skin market to form a breathable skirt 34', thereby reducing the manufacturing cost. Moreover, since the knitted fabric has elasticity, the breathable skirt 34 can be rotated under appropriate tension without providing other special tensioning means. In addition to the woven breathable skirt 34 made of knitted or woven fabric, a breathable skirt 34 may be formed by perforating a resin belt formed of rubber or an elastic resin. It is also possible to adopt a configuration in which a rotating shaft 35 of a bottom jaw roller 35a is formed thereon, which is a shaft member which is distributed by all the spindle units, and is connected by a motor: The gear end is driven like a row of gears of the bottom rollers 1 2 to 14 of the drafting device 1 1 .
