Description

  The present invention relates to a spinning take-up device that takes up a plurality of yarns spun from a spinning device.

  Japanese Patent Application Laid-Open No. 2004-228561 discloses a device that takes up a plurality of yarns spun from a spinning device. This device has a supply roller and a drawing roller installed below the spinning device, and a winding unit (spindle) arranged further below the roller. A plurality of yarns spun from the spinning device are drawn between a supply roller and a drawing roller, and then wound around a winding unit.

  When threading, a plurality of yarns spun from the spinning device are wound around a supply roller and a drawing roller installed in the first processing region, and then the plurality of yarns are transferred to the second processing region below, It winds around the winding part installed in the 2nd processing field. Specifically, first, the operator uses a guide roller that can move between the first processing region and the second processing region while holding the plurality of yarns wound around the drawing roller with a suction gun. Multiply. Next, the guide roller is moved from the first processing area to the second processing area. When the guide roller is moved to the second processing area, the operator operates the catching nozzle in the second processing area to capture each of the plurality of yarns wound around the guide roller and wind them around the winding unit. .

JP-A-54-88315

  By the way, in a general spinning take-up device, the distance between the spinning device and the lower winding equipment is considerably large (for example, about 3 to 6 m). Therefore, in the apparatus of Patent Document 1, when the yarn is moved toward the lower winding portion by the guide roller, the bending angle of the yarn path that is folded back into a V shape with the guide roller as the apex becomes considerably small. For this reason, in the vicinity of the guide roller, the upstream yarn portion and the downstream yarn portion of the guide roller are arranged close to each other.

  In Patent Document 1, the operator captures the yarn by sucking the yarn portion upstream of the guide roller with a catching nozzle. At this time, if the upstream yarn portion and the downstream yarn portion are close to each other, not only the upstream yarn portion but also the downstream yarn portion is accidentally sucked, and the yarn to the catching nozzle is sucked. A delivery failure may occur.

  Here, if the size of the guide roller is considerably increased, the distance between the upstream yarn portion and the downstream yarn portion is increased, so that the yarn can be received in the vicinity of the guide roller. However, as the size of the guide roller increases, the size of the entire device for unwinding the yarn also increases. Further, when a free rotating roller having no drive source is used as the guide roller, the contact resistance between the yarn and the roller increases as the roller size increases, and the success rate of yarn delivery due to yarn breakage decreases.

  Further, when a yarn is hung on one guide roller and lowered, the yarn delivery position in the lower space where the yarn is lowered is limited to the yarn portion upstream of the guide roller. For this reason, the degree of freedom of design of the device for receiving the yarn is narrowed, and the success rate of the yarn delivery may be reduced.

  An object of the present invention is to increase the success rate of delivery of the yarn lowered by the yarn lowering device.

Means for Solving the Problems and Effects of the Invention

The spinning take-up device of the first invention is a spinning take-up device that takes out a plurality of yarns spun from a spinning device installed in the first yarn processing space,

The yarn hooking device 23 receives the plurality of yarns Y lowered by the yarn lowering device 4 and hooks the yarns onto the two godet rollers 15 and 16 of the take-up unit 6.

  FIG. 6 is a diagram showing the spinning take-up device 1 immediately after the start of spinning. Examples of the work that the operator on the second floor periodically performs after the yarn spun from the spinneret 10a is once cut and the spinning production is once stopped are as follows. First, there is a cleaning operation of the spinneret 10a of the spin pack 10. This is an operation of removing deposits attached to the spinneret 10a and spraying silicone with a spray, for example, almost every day. In addition, there is an operation of exchanging the spin pack 10, and in an apparatus for producing yarn for clothing, for example, the frequency is about once a week. When production is started again after these operations are performed, a plurality of yarns Y spun from the spinneret 10a are sequentially applied from the guides 13 and 14 to the take-up unit 6 and the winding device 7. There is a need.

  When performing the above threading, the operator on the second floor first installs the inclined plate 51 on the lower side of the cooling unit 3. The inclined plate 51 is for receiving the polymer 52 so that the polymer 52 flowing out from the spinneret 10a does not fall to the first floor during the above-described preparatory work. When the inclined plate 51 is installed, if the yarn suction device 47 is disposed around the thread passage hole 9a of the partition wall 9, the installation of the inclined plate 51 may be obstructed. In that case, it is preferable to move the yarn suction device 47 in advance to a position away from the periphery of the yarn passage hole 9a.

  FIG. 7 is a view showing the spinning take-up device 1 during yarn holding by the yarn suction device. FIG. 8 is a view showing the spinning take-up device 1 when threading the oil agent guide 13 and the yarn regulating guide 14. FIG. 9 is a view showing the spinning take-up device 1 when yarn is threaded onto the yarn focusing guide 46. FIG. 10 is a view showing the spinning take-up device 1 immediately before the yarn is unwound.

  When the plurality of yarns Y can be spun from the spinning device 2, the operator on the second floor sends the plurality of yarns Y spun from the spinneret 10a to the yarn suction device 47 located behind the yarn passage hole 9a. As shown in FIG. 7, the plurality of yarns Y are sucked and held by the yarn suction device 47. When the yarn suction device 47 holds the plurality of yarns Y, the inclined plate 51 is removed. In addition, as shown in FIG. 8, the operator hangs the plurality of yarns Y spun from the spinneret 10 a on the oil agent guide 13 and the yarn regulation guide 14.

  Next, as shown in FIGS. 5 and 9, the plurality of yarns Y sucked by the yarn suction device 47 are hung on the yarn focusing guide 46 protruding to the yarn passage hole 9 a slightly on the front side of the yarn suction device 47. . As a result, the plurality of yarns Y sucked into the yarn suction device 47 are converged. Further, as shown in FIG. 10, a plurality of yarns Y in a converged state are sequentially hung on the two yarn hooking portions 42 of the yarn lowering device 4. As described above, the plurality of yarns Y sucked by the yarn suction device 47 are hung on the yarn collecting guide 46 and converged, so that the plurality of yarns Y can be hung on the two yarn hooking portions 42 in a converged state. Threading is easy. Further, when the yarn lowering device 4 lowers the yarns Y, it is difficult for the plurality of yarns Y to fall apart.

  When the plurality of yarns Y are held in the yarn lowering device 4, the operator on the second floor operates the operation switch 50 for yarn lowering. When the yarn lowering signal from the operation switch 50 is sent to the control device 8, the control device 8 controls the fluid supply unit 44 (see FIG. 2) to operate the lifting cylinder 40 and lower the yarn lowering device 4. .

  FIG. 11 is a view showing the spinning take-up device 1 immediately after the yarn lowering device 4 is lowered. As shown in FIG. 11, the yarn lowering device 4 descends from the second floor through the yarn passage hole 9a of the partition wall 9, and the plurality of yarns Y held by the yarn lowering device 4 are lowered to the first floor. At this time, the yarn Y forms a substantially V-shaped yarn path from the spinning device 2 on the second floor through the yarn lowering device 4 on the first floor to the yarn suction device 47 on the second floor again. Further, since the yarn lowering device 4 descends along a path behind the yarn path YP at the time of yarn production, the plurality of yarns Y held by the yarn lowering device 4 also follow the yarn path YP. It is lowered to the position shifted to the side.

  When the yarn lowering device 4 reaches a lower limit position in the vicinity of the yarn holding section 5 on the first floor, the state is detected by the lowering detection sensor 49. Upon receiving this detection signal, the control device 8 stops the descent of the yarn lowering device 4 by the elevating cylinder 40, and waits the yarn lowering device 4 at the lower limit position for a predetermined waiting time. The waiting time is appropriately set according to the time required to deliver the plurality of yarns Y to the yarn hooking device 23 or the yarn holding unit 5 described below.

  The plurality of yarns Y lowered to the first floor by the yarn lowering device 4 are delivered to the yarn hooking device 23 in order to hook the yarn onto the take-up unit 6. Here, if the yarn threading device 23 has already reached the front of the spinning take-up device 1 and is waiting, the plurality of yarns Y are directly transferred from the yarn lowering device 4 to the yarn threading device 23. On the other hand, when the yarn Y is lowered while the yarn hooking device 23 is not waiting, the plurality of yarns Y are once delivered to the yarn holding unit 5 and then the yarn hooking device 23 moves. The yarn is transferred from the yarn holder 5 to the yarn hooking device 23. Based on the positional information of the yarn hooking device 23, the control device 8 determines whether the yarn Y lowered by the yarn lowering device 4 is transferred to the yarn hooking device 23 or the yarn holding unit 5.

(1) Delivery of yarn to the yarn hooking device 23 First, the delivery of the yarn Y from the yarn lowering device 4 to the yarn hooking device 23 will be described. FIG. 12 is a view showing the spinning take-up device 1 at the time of yarn delivery to the yarn hooking device 23. FIG. 13 is a view showing the spinning take-up device 1 when yarn is threaded by the yarn hooking device 23. When the detection signal of the descent detection sensor 49 is received, the control device 8 causes the yarn hooking device 23 to receive the yarn Y from the yarn lowering device 4.

  As shown in FIG. 12, a cutter 54 and a yarn suction portion 55 are provided at the tip of the yarn hooking arm 25 of the yarn hooking device 23. First, the yarn hooking device 23 positions the tip end of the yarn hooking arm 25 between the spinning device 2 and the yarn lowering device 4, that is, upstream of the yarn hooking portion 42 on the front side (upstream side in the yarn traveling direction). Move to. At this position, the cutter 54 is operated to cut each yarn Y at the yarn portion Ya on the upstream side of the yarn lowering device 4. The cut yarn Y is sucked and held by the yarn suction portion 55 disposed in the vicinity of the cutter 54.

  Here, since the yarn lowering device 4 has two yarn hooking portions 42, as shown in FIG. 12, the yarn portion Ya on the upstream side of the yarn lowering device 4 and the yarn portion Yb on the downstream side of each yarn Y, as shown in FIG. The space between is widened. For this reason, when the yarn hooking device 23 cuts the upstream yarn portion Ya, the downstream yarn portion Yb is unlikely to be cut together.

  When the plurality of yarns Y are held on the yarn hooking arm 25, as shown in FIG. 13, the yarn hooking device 23 operates the yarn hooking arm 25 to put the plurality of yarns Y on the godet rollers 15 and 16 of the take-up section 6. Multiply in order. On the other hand, after the delivery of the yarn Y to the yarn hooking device 23 is finished, the yarn lowering device 4 does not need to remain on the first floor. Therefore, after the above-described waiting time has elapsed, the control device 8 raises the yarn lowering device 4 by the elevating cylinder 40 and returns it to the second floor. Note that after the yarn Y is delivered, the yarn lowering device 4 does not automatically return to the second floor, but the operator may operate the operation switch 50 to manually return the yarn lowering device 4 to the second floor. Good.

  Here, the yarn lowering device 4 moves up and down along a path behind the yarn path YP at the time of production of the first floor yarn, and lowers the plurality of yarns Y at positions shifted from the yarn path YP. Therefore, even if the yarn lowering device 4 is returned to the second floor in a state where the yarn Y is delivered to the yarn hooking device 23 on the first floor and the yarn Y is hung on the take-up unit 6, the yarn lowering device 4 It does not interfere with the plurality of yarns Y hung on the take-up section 6.

(2) Delivery of Yarn to Yarn Holding Unit 5 Next, delivery of the yarn Y from the yarn lowering device 4 to the yarn holding unit 5 will be described. FIG. 14 is a diagram showing the spinning take-up device 1 when delivering the yarn to the yarn holding unit 5. FIG. 15 is a view showing the spinning take-up device 1 after completion of yarn delivery to the yarn holding unit 5. When receiving the detection signal of the descent detection sensor 49, the control device 8 sends a control signal to the yarn holding drive unit 53 (see FIG. 2) that swings and drives the yarn holding member 45 and the yarn holding unit 5 to hold the yarn. The yarn Y is transferred to the unit 5.

  First, the yarn gathering drive unit 53 swings the yarn gathering member 45 from the retracted position in FIG. 11 to the yarn gathering position in FIG. Thereby, as shown in FIG. 14, the plurality of yarns Y lowered by the yarn lowering device 4 are brought close to the yarn path YP at the time of yarn production.

  Next, the yarn holding unit 5 sucks and holds the plurality of yarns Y brought together by the yarn gathering member 45. Specifically, the suction pipe 21 is advanced by the fluid cylinder 27 as shown in FIG. Then, the plurality of yarns Y lowered by the yarn lowering device 4 are cut by the cutter 22 provided at the tip of the suction pipe 21. The plurality of cut yarns Y are sucked and held in the suction pipe 21. Thereby, as shown in FIG. 15, the plurality of yarns Y lowered by the yarn lowering device 4 are delivered to the yarn holding unit 5. Thereafter, similarly to the delivery of the yarn Y to the yarn hooking device 23, after the elapse of a predetermined waiting time, the control device 8 raises the yarn lowering device 4 by the lifting cylinder 40 and returns it to the second floor.

  As described above, the yarn holding unit 5 of the present embodiment can suck the plurality of yarns Y lowered by the yarn lowering device 4 at positions shifted from the yarn path YP at the time of yarn production. Therefore, there is no need to wait for the yarn hooking device 23 in advance when unloading the plurality of yarns Y from the second floor. That is, an operator who is working on the second floor can unload a plurality of yarns at an appropriate timing regardless of whether the yarn hooking device 23 is waiting on the first floor.

  After the delivery of the yarn Y to the yarn holder 5 in FIG. 15, the yarn hooking device 23 (see FIG. 1) moves to the front of the spinning take-up device 1. The yarn hooking device 23 cuts a plurality of yarns Y held by the yarn holding unit 5 with a cutter 54 and sucks and receives the yarns with a yarn suction unit 55. Thereafter, the yarn hooking device 23 moves the yarn hooking arm 25 to hook the plurality of yarns Y onto the godet rollers 15 and 16 of the take-up unit 6.

  In the spinning take-up device 1 according to the present embodiment described above, the yarn lowering device 4 has two yarn hooking portions 42 arranged at intervals in the front-rear direction, and each yarn Y has two yarn hooking portions 42. It is multiplied in order. When each yarn Y is hung on the two yarn hooking portions 42, the yarn portion Ya on the upstream side and the yarn portion Yb on the downstream side of the yarn lowering device 4 are separated. This prevents one yarn Y from being accidentally cut and captured at two locations by the cutter 54 of the yarn hooking device 23 or the cutter 22 of the yarn holding unit 5. The delivery success rate increases.

  The separation distance L in the front-rear direction of the two thread hooks 42 is preferably 30 mm or more, and more preferably 120 mm or more. As a result, the separation distance between the two yarn portions Ya and Yb that are respectively hung on the two yarn hooking portions 42 of one yarn Y is increased. Therefore, it is reliably prevented that one yarn Y is mistakenly captured at two places. If the separation distance L is 120 mm or more, the yarn hooking arm 25 itself can pass between the two yarn hooking portions 42, and the yarn Y can be easily transferred to the yarn hooking arm 25. Even if the separation distance L is smaller, if at least about 30 mm, only a part of the yarn hooking arm 25 (for example, the cutter 54 and the yarn suction portion 55) is advanced, so that the yarn Y can be moved without any particular trouble. Delivery is possible.

  Next, modified embodiments in which various modifications are made to the embodiment will be described. However, components having the same configuration as in the above embodiment are given the same reference numerals and description thereof is omitted as appropriate.

1] In the above-described embodiment, the plurality of yarns Y lowered to the first floor by the yarn lowering device 4 are transferred to the yarn hooking device 23, and the yarn hooking device 23 performs yarn hooking to the take-up unit 6. However, the yarn hooking device 23 is not essential. That is, a plurality of yarns Y lowered to the first floor by the yarn lowering device 4 may be directly received by the operator on the first floor with a suction gun and manually threaded. Even in this case, the distance between the upstream yarn portion Ya and the downstream yarn portion Yb is separated by the two yarn hooking portions 42 of the yarn lowering device 4, so that one yarn Y is mistakenly placed at two locations. It is prevented that it is captured by.

2] In the above embodiment, the yarn lowering device 4 moves up and down the path behind the yarn path YP at the time of yarn production, and puts the plurality of yarns Y at positions shifted rearward from the yarn path YP on the first floor. It has been lowered. On the other hand, the positions where the plurality of yarns Y are lowered may be shifted forward with respect to the yarn path YP, or may be shifted left and right.

  In particular, in the above-described embodiment, the yarn hooking device 23 moves to the front side of the spinning take-up device 1, and the yarn hooking device 23 performs the yarn hooking from the front. In this case, when the yarn lowering device 4 is configured to lower the plurality of yarns Y at positions shifted before the yarn path YP, the yarn hooking device 23 removes the plurality of yarns Y from the yarn lowering device 4. It becomes easier to receive. This is the same when the operator receives the yarn Y from the front with a suction gun.

3] In the above-described embodiment, the yarn moving member 45 moves the plurality of yarns Y to the yarn holding unit 5 by swinging, but is not limited to such a configuration. For example, as disclosed in Japanese Patent Laid-Open No. 2013-57148 (FIG. 10), a plurality of yarns may be brought together by a linear motion.

  Further, the yarn shifting member is not an essential component. For example, when a plurality of yarns Y are lowered by the yarn lowering device 4 to a position shifted to the right side (front side in FIG. 1) with respect to the yarn path YP during yarn production, The plurality of yarns Y can be sucked by the yarn holding unit 5. That is, as shown in FIG. 3, the yarn holding portion 5 is provided at the suction pipe 21 that advances and retreats in the left-right direction (the direction in which the plurality of yarns Y are separated / approached) and the tip portion of the suction pipe 21. It has a cutter 22. Even if the positions where the plurality of yarns Y are lowered are shifted to the right with respect to the yarn path YP, the suction pipe 21 advances and the cutter 22 moves to the right, whereby the plurality of yarns Y are cut. The plurality of yarns Y cut by the cutter 22 are sucked by the suction pipe 21. In this embodiment, the tip end portion of the suction pipe 21 of the yarn holding portion 5 corresponds to the second yarn suction portion of the present invention.

4] On the second floor of the building, the yarn suction device 47 that sucks and holds the plurality of yarns Y spun from the spinning device 2 may be a portable device such as a suction gun. In one spinning take-up device 1, the operator finishes the work on the second floor, lowers the yarn lowering device 4 to the first floor, and the delivery of the plurality of yarns Y to the yarn hooking device 23 or the yarn holding unit 5 is completed. As a result, the yarn Y is separated from the yarn suction device 47 on the second floor (see FIGS. 13 and 15). That is, the role of the yarn suction device 47 ends at that time. Therefore, when the yarn unloading is completed in one spinning take-up device 1, the yarn suction device 47 is picked up and moved to another place, and other work (for example, preparatory work for the other spinning take-up device 1) is performed. Is possible.

5] In the above embodiment, the yarn hooking device 23 receives the yarn Y by cutting the yarn portion Ya upstream of the yarn lowering device 4 for each of the plurality of yarns Y. On the other hand, as shown in FIG. 16, the yarn hooking device 23 may receive the yarn Y by cutting the yarn Y between the two yarn hooking portions 42. Even in this case, it is difficult for one thread to be accidentally cut at two places. Further, since the vibration of the yarn Y between the two yarn hooking portions 42 is suppressed by being close to the yarn hooking portion 42, the success rate of the yarn cutting is increased. Similarly, when the yarn holding unit 5 receives the yarn Y or when the operator performs yarn hooking using a suction gun, the yarn Y is cut between the two yarn hooking portions 42 to receive the yarn. May be performed.

  Further, since each yarn is hung on the two yarn hooking portions, each yarn is placed on the upstream side of the yarn lowering device 4, on the position between the two yarn hooking portions 42, on the downstream side of the yarn lowering device 4. It is possible to cut and deliver the yarn Y at three positions. Therefore, the capture location may be made different depending on the size of the instrument used for delivery of the yarn Y. For example, it is assumed that the size of the yarn holding portion 5 is larger than the size of the tip portion of the yarn hooking arm 25 of the yarn hooking device 23. In this case, when the yarn Y is received by the large size yarn holder 5, the yarn portion Ya on the upstream side of the yarn lowering device 4 is cut and the yarn Y is received as shown in FIG. On the other hand, when the yarn Y is received by the small-sized yarn hooking device 23, the yarn Y is cut between the two yarn hooking portions 42 and received as shown in FIG.

6] In the above-described embodiment, the two yarn hooking portions 42 of the yarn lowering device 4 are arranged at intervals in the front-rear direction, but the direction in which the two yarn hooking portions 42 are arranged (that is, upstream of the yarn lowering device 4). The direction in which the yarn portion on the side and the yarn portion on the downstream side are separated from each other may be any direction as long as it intersects the vertical direction. For example, the two yarn hooking portions 42 may be arranged at intervals in the left-right direction.

7] The number of yarn hooking portions 42 of the yarn lowering device 4 is not limited to two, and may be three or more. In that case, it is preferable that the distance between the two yarn hooking portions 42 at both ends in the direction intersecting the vertical direction among the plurality of yarn hooking portions 42 is more than a certain distance (for example, 30 mm).

8] The yarn hooking portion of the yarn lowering device 4 may be a roller configured to be rotatable. In this case, damage to the yarn Y at the yarn hooking portion is reduced, and yarn breakage during yarn hooking is suppressed.

9] The ascending detection sensor 48 and the descending detection sensor 49 for detecting that the yarn lowering device 4 has reached the upper limit position and the lower limit position, respectively, are not essential components. For example, if a position-controllable motor such as a servomotor is used as the drive unit that moves the yarn lowering device 4 up and down, the sensors 48 and 49 are not necessary. Further, the operator may manually stop the yarn lowering device 4 while visually checking the position of the yarn lowering device 4, and in this case, the sensors 48 and 49 are not necessary.

10] The spinning take-up apparatus of the above embodiment is an apparatus for POY production in which the yarn Y spun from the spinning apparatus 2 is wound around the package P as it is without stretching, but the spun yarn Y is It may be an apparatus for FDY production in which it is stretched and wound around the package P. In this FDY production apparatus, in addition to the two godet rollers 15, 16, the take-up unit 6 is arranged on the upstream side in the traveling direction from these rollers 15, 16, and a plurality of pulling units 6 are used for drawing the yarn Y. A stretching roller is further provided.
