However, in a typical spinning traction device, the distance between the spinning device and the winding device below is relatively large (for example, about 3 m to 6 m). Therefore, in the apparatus of the above-mentioned Patent Document 1, when the yarn is moved toward the lower winding portion by the guide roller, the bending angle of the yarn passage which is folded in a V shape with the guide roller as the apex becomes relatively small. . Therefore, in the vicinity of the guide roller, the yarn portion on the upstream side of the guide roller is disposed in close proximity to the yarn portion on the downstream side.

Further, in Patent Document 1, the operator captures the yarn by sucking the yarn portion on the upstream side of the guide roller by the catching nozzle. At this time, it is conceivable that when the yarn portion on the upstream side is too close to the yarn portion on the downstream side, not only the yarn portion on the upstream side but also the yarn portion on the downstream side is sucked into the catching nozzle by mistake.

Here, if the size of the guide roller is made relatively large, the distance between the yarn portion on the upstream side and the yarn portion on the downstream side becomes large, so that the yarn can be received in the vicinity of the guide roller. But when guiding When the size of the roller is increased, the size of the entire device for lowering the yarn is also increased. Further, in the case where the free-rotation roller having no drive source is used as the guide roller, if the roller size becomes large, the contact resistance between the yarn and the roller becomes large, and the yarn transfer succeeds due to the yarn breakage. The rate will decrease.

Further, when the yarn is hung on one guide roller to lower the yarn, the yarn delivery position in the space below the yarn supply reduction is limited to the yarn portion on the upstream side of the guide roller. Therefore, the degree of freedom in designing the device for taking the yarn becomes small, and there is also a concern that the success rate of the yarn is lowered.

An object of the present invention is to improve the delivery success rate of a yarn which is lowered downward by a yarn dropping device.

Further, the yarn suction device 47 may be formed to be able to move away from or close to the yarn passage hole 9a in the horizontal direction parallel to the partition wall 9. In this case, the yarn suction device 47 can be disposed around the yarn passage hole 9a only at the time of the yarn drop, and can be retracted from the yarn passage hole 9a without causing any trouble during the other work.

As shown in Figs. 4 and 5, a yarn bundling guide 46 is disposed between the yarn lowering device 4 and the yarn suction device 47, and the yarn bundling guide 46 is configured to protrude to the partition wall. The yarn of 9 passes over the hole 9a. The yarn bundle guide 46 can bundle a plurality of yarns Y attracted by the yarn suction device 47.

At the position on the upper side of the yarn passing hole 9a of the partition wall 9 on the second floor, a rise detecting sensor 48 for detecting the case where the lowering device 4 is at the upper limit position is provided. On the other hand, a lowering detecting sensor 49 for detecting that the lowering device 4 has reached the lower limit position is provided at a position on the lower side of the yarn holding portion 5 on the first floor. In addition, the rising detection sensor 48 and the falling detection sensor 49 are not limited to a specific sensing. Device. For example, any of a contact sensor and a non-contact sensor can be employed.

A yarn plucking member 45 (the yarn plucking portion of the present invention) is disposed at a position slightly below the yarn holding portion 5 provided on the first floor. The yarn arranging member 45 is a member that closes the yarn Y that is lowered by the yarn passage YP at the time of the production of the yarn to the yarn holding portion 5 located in the vicinity of the yarn passage YP. The yarn plucking member 45 is driven by a yarn plucking drive unit 53 (see FIG. 2) composed of a cylinder, a motor, or the like, and is capable of retracting the yarn (Fig. 4) and the yarn without interfering with the yarn Y. Y is swung in the horizontal plane between the yarn plucking positions (Fig. 14) in which the yarn holding portion 5 is approaching.

(hanging work)

Next, when the production of the yarn Y is started by the spinning and pulling device 1 with reference to FIGS. 6 to 11 , the preparation work of the operator who performs the yarn hooking or the like and the operation of the spinning and pulling device 1 at this time will be described. Before the yarn production starts, the operator stands on the second floor at a position further rearward than the yarn passing hole 9a of the partition wall 9, and the operator performs the cleaning operation of the spinning device 2 and the operation related to the yarn lowering device 4 . On the other hand, as shown in Fig. 1, a yarn hooking device 23 that can move in the left-right direction (the direction perpendicular to the paper surface of Fig. 1) is provided on the first floor. When the yarn hook request signal from a certain spinning traction device 1 is received, the yarn hooking device 23 moves toward the device. Then, the yarn hooking device 23 receives the plurality of yarns Y which have been lowered by the yarn dropping device 4, and respectively hooks the yarns to the two yarn guiding rollers 15, 16 of the pulling portion 6.

Fig. 6 is a view showing the spinning take-up device 1 after the start of spinning. In the case where the yarn spun from the yarn discharging head 10a is temporarily cut and the spinning production is once stopped, the work to be performed periodically by the operator on the second floor is as follows. First, the cleaning operation of the yarn discharging head 10a of the spinning unit 10 is performed. This is an operation of removing the precipitate attached to the yarn discharge head 10a and spraying the crucible with a sprayer, for example, almost every day. Further, there is also an operation of replacing the spinning unit 10, and the apparatus for producing the yarn for the clothing is carried out, for example, at a frequency of about once a week. After the execution of these operations, when the production is started again, it is necessary to sequentially suspend the plurality of yarns Y spun from the yarn discharging head 10a from the guides 13, 14 to the pulling portion 6 and the winding device 7.

When the above-described yarn hooking is performed, the operator on the second floor first sets the inclined plate 51 on the lower side of the cooling portion 3. The inclined plate 51 is for receiving the polymer 52 so that the polymer 52 flowing out of the yarn discharging head 10a does not fall to the first floor in the above preparation work. In addition, when the inclined plate 51 is provided, if the yarn suction device 47 is disposed around the yarn passing hole 9a of the partition wall 9, the installation of the inclined plate 51 may be hindered. In this case, it is preferable to move the yarn suction device 47 to a position away from the periphery of the yarn passage hole 9a in advance.

Fig. 7 is a view showing the spinning and pulling device 1 when the yarn is held by the yarn suction device. Fig. 8 is a view showing the spinning and pulling device 1 when the yarn guiding device 13 and the yarn regulating guide 14 are hooked. Fig. 9 is a view showing the spinning and pulling device 1 when the yarn bundle guide 46 is hooked. Figure 10 shows the pre-winding A diagram of the spinning traction device 1.

When it has become a state in which a plurality of yarns Y can be spun from the spinning device 2, the operator on the second floor guides the plurality of yarns Y spun from the yarn discharging head 10a to the rear of the yarn passing holes 9a. The yarn suction device 47 causes the yarn suction device 47 to suck and hold the plurality of yarns Y as shown in Fig. 7 . When the yarn suction device 47 has held the plurality of yarns Y, the inclined plate 51 is removed. Further, as shown in Fig. 8, the operator hangs a plurality of yarns Y spun from the yarn discharging head 10a on the oil guide 13 and the yarn restriction guide 14.

Next, as shown in Fig. 5 and Fig. 9, the plurality of yarns Y sucked by the yarn suction device 47 are hung on the yarn front suction side of the yarn suction device 47, and are hung on the yarn extending through the yarn passage hole 9a. Line bundle guide 46. Thereby, the plurality of yarns Y sucked by the yarn suction device 47 are bundled. Further, as shown in Fig. 10, a plurality of yarns Y in a bundled state are sequentially hung on the two yarn hooking portions 42 of the yarn dropping device 4. In this way, the plurality of yarns Y attracted by the yarn suctioning device 47 are hung on the yarn bundling guide 46 to be bundled, so that a plurality of yarns Y can be hung in the bundled state. The yarn hooking portions 42 make the yarn hanging operation easy. Further, when the yarn drop device 4 is lowered, the plurality of yarns Y are less likely to become scattered.

When the yarn returning device 4 holds a plurality of yarns Y, the operator on the second floor operates the operation switch 50 for lowering the yarn. When the downshift signal from the operation switch 50 is transmitted to the control device 8, the control device 8 controls the fluid supply unit 44 (see Fig. 2) to actuate the lift cylinder 40 to lower the yarn drop device 4.

Fig. 11 is a view showing the spinning take-up device 1 in which the lowering device 4 is lowered. As shown in Fig. 11, the yarn lowering device 4 is lowered from the second floor through the yarn passing 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 is formed into a substantially V-shaped yarn passage from the spinning device 2 on the second floor to the yarn drawing device 47 on the second floor through the yarn lowering device 4 on the first floor. Further, the yarn lowering device 4 is lowered along the path on the rear side of the yarn passage YP at the time of yarn production, so that the plurality of yarns Y held by the yarn lowering device 4 are also lowered to be more rearward than the yarn passage YP. The side is offset from the open position.

When the lowering device 4 reaches the lower limit position near the yarn holding portion 5 of the first floor, the state is detected by the lowering detecting sensor 49. Upon receiving the detection signal, the control device 8 stops the lowering of the yarn lowering device 4 by the lift cylinder 40, and causes the yarn lowering device 4 to stand by at the lower limit position for a predetermined standby time. Further, the standby time is appropriately set in accordance with the time required to transfer the plurality of yarns Y to the yarn hooking device 23 or the yarn holding portion 5 as will be described later.

The plurality of yarns Y that have been lowered to the first floor by the yarn dropping device 4 are delivered to the yarn hooking device 23 in order to perform yarn hooking to the pulling portion 6. Here, if the yarn hooking device 23 has reached the front of the spinning and pulling device 1 and is in the standby state, the plurality of yarns Y will be directly transferred from the yarn dropping device 4 to the yarn hooking device 23. On the other hand, when the yarn Y is lowered while the yarn hooking device 23 is not in standby, the plurality of yarns Y are temporarily transferred to the yarn holding portion 5, and thereafter, after the yarn hooking device 23 is moved, The yarn holding device 5 is delivered from the yarn holding portion 5. Control device 8 Based on the positional information of the yarn hooking device 23, it is judged whether the yarn Y to be lowered by the yarn dropping device 4 is to be delivered to the yarn hooking device 23 or to be handed over to the yarn holding portion 5.

(1) Handing over the yarn to the yarn hooking device 23

First, the case where the yarn Y is transferred from the yarn dropping device 4 to the yarn hooking device 23 will be described. Fig. 12 is a view showing the spinning and pulling device 1 when yarn feeding is performed to the yarn hooking device 23. Fig. 13 is a view showing the spinning and pulling device 1 when the yarn hooking device 23 performs the yarn hooking. Upon receiving the detection signal of the falling detection sensor 49, the control device 8 causes the yarn hooking device 23 to perform the receiving operation of the yarn Y received from the yarn lowering device 4.

As shown in Fig. 12, a cutter 54 and a yarn suction portion 55 are provided at the front end portion of the yarn hooking arm 25 of the yarn hooking device 23. First, the yarn hooking device 23 moves the front end portion of the yarn hooking arm 25 between the spinning device 2 and the yarn dropping device 4, that is, the upstream side of the yarn hooking portion 42 on the front side (upstream side in the yarn traveling direction). s position. At this position, the cutter 54 is actuated, and each yarn Y is cut on 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 close to the cutter 54.

Here, since the yarn drop device 4 has two yarn hooking portions 42, as shown in Fig. 12, the yarn portion Ya of the yarn Y of the respective yarn Y is further on the upstream side and the yarn of the downstream side. Part of Yb has been enlarged. Therefore, when the yarn portion Ya on the upstream side is cut by the yarn hooking device 23, it is difficult to cause the yarn portion Yb on the downstream side to be cut together. The situation.

When the yarn hooking arm 25 has held the plurality of yarns Y, as shown in Fig. 13, the yarn hooking device 23 operates the yarn hooking arm 25, and sequentially guides the plurality of yarns Y to the guide portion of the tractor unit 6. Yarn rolls 15, 16. On the other hand, after the delivery of the yarn Y to the yarn hooking device 23 is completed, the yarn lowering device 4 does not have to stay on the first floor. Therefore, after the standby time has elapsed, the control device 8 raises the yarn dropping device 4 by the lift cylinder 40 and returns to the second floor. Alternatively, after the delivery of the yarn Y is completed, the yarn lowering device 4 does not automatically return to the second floor, and the operator operates the operation switch 50 to manually return the yarn lowering device 4 to the second floor.

Here, the yarn drop device 4 is moved up and down along a path on the rear side of the yarn passage YP at the time of yarn production on the first floor, and the plurality of yarns Y are lowered to a position deviated from the yarn opening passage YP. Therefore, after the yarn Y on the first floor is transferred to the yarn hooking device 23, the yarn Y is hung in the state of the pulling portion 6, and even if the yarn lowering device 4 is returned to the second floor, the yarn lowering device 4 does not hang. The plurality of yarns Y of the traction portion 6 interfere.

(2) Handing the yarn to the yarn holding portion 5

Next, a case where the yarn Y is delivered from the yarn lowering device 4 to the yarn holding portion 5 will be described. Fig. 14 is a view showing the spinning and pulling device 1 when the yarn is transferred to the yarn holding portion 5. Fig. 15 is a view showing the spinning retracting device 1 after the yarn is delivered to the yarn holding portion 5. When the detection signal of the falling detection sensor 49 is received, the control device 8 moves the yarn driving unit 53 that oscillates the yarn plucking member 45 (see FIG. 2) and The yarn holding unit 5 transmits a control signal to transfer the yarn Y to the yarn holding unit 5.

First, the yarn plucking drive unit 53 swings the yarn plucking member 45 from the retracted position of Fig. 11 to the yarn plucking position of Fig. 14. Thereby, as shown in Fig. 14, the plurality of yarns Y which have been lowered by the yarn dropping device 4 are brought close to the yarn passage YP at the time of yarn production.

Next, the yarn holding portion 5 holds and holds a plurality of yarns Y that are brought close by the yarn arranging member 45. Specifically, as shown in FIG. 3(b), the suction pipe 21 is advanced by the fluid pressure cylinder 27. Then, the plurality of yarns Y that have been lowered by the yarn drop device 4 are cut by the cutter 22 provided at the front end portion of the suction pipe 21. Further, the plurality of cut yarns Y are sucked into the suction tube 21 and held. As a result, as shown in Fig. 15, the plurality of yarns Y reduced by the yarn dropping device 4 are delivered to the yarn holding portion 5. Thereafter, similarly to the case where the yarn Y is transferred to the yarn hooking device 23, after a predetermined waiting time has elapsed, the control device 8 raises the yarn lowering device 4 by the lift cylinder 40 and returns to the second floor.

Therefore, the yarn holding portion 5 of the present embodiment can attract the plurality of yarns Y which are lowered by the yarn dropping device 4 to the position of the yarn passage YP when the yarn is opened. Therefore, when the plurality of yarns Y are lowered from the second floor, it is not necessary to stand the yarn hooking device 23 in advance. That is, the operator who is working on the second floor can reduce the number of yarns at an appropriate timing regardless of whether or not the yarn hooking device 23 is on the first floor standby.

The yarn Y is transferred to the yarn holding portion 5 of Fig. 15 Thereafter, the yarn hooking device 23 (refer to FIG. 1) moves toward the front of the spinning and pulling device 1. The yarn hooking device 23 cuts the plurality of yarns Y held by the yarn holding portion 5 by the cutter 54, and receives a plurality of yarns Y by suction of the yarn suction portion 55. Thereafter, the yarn hooking device 23 causes the yarn hooking arm 25 to actuate, and the plurality of yarns Y are hung on the yarn guiding rollers 15, 16 of the pulling portion 6.

In the spinning retracting device 1 of 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 is hung in two rows in sequence. Yarn portion 42. Each of the yarns Y is hung on the two yarn hooking portions 42, and the yarn portion Ya on the upstream side and the yarn portion Yb on the downstream side are further away from each other than the yarn lowering device 4. Therefore, it is possible to prevent one yarn Y from being caught by the cutter 54 of the yarn hooking device 23 or the cutter 22 of the yarn holding portion 5 at two places, thereby improving the success rate of the yarn Y. .

The separation distance L in the front-rear direction of the two yarn-hanging portions 42 is preferably 30 mm or more, more preferably 120 mm or more. As a result, the separation distance of the two yarn portions Ya and Yb of one yarn Y which are respectively hung on the two yarn hooking portions 42 becomes large. Therefore, it is possible to surely prevent one yarn Y from being caught by mistake at two places. Further, when 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. In addition, even when the separation distance L is smaller, it is possible to advance only a part of the hook arm 25 (for example, the cutter 54 and the yarn suction unit 55) as long as it is at least about 30 mm. The transfer of the yarn Y is carried out without particular hindrance.

Next, a modified embodiment in which various modifications are added to the above embodiment will be described. Here, members having the same configurations as those of the above-described embodiment are denoted by the same reference numerals, and the description thereof will be appropriately omitted.

1] In the above embodiment, the plurality of yarns Y which are lowered to the first floor by the yarn dropping device 4 are transferred to the yarn hooking device 23, and the yarn hooking device 23 performs yarn hooking to the pulling portion 6, but the yarn hooking device 23 Not a must. That is, it is also possible to directly use the suction gun to receive the plurality of yarns Y which are lowered to the first floor by the lowering device 4 by the operator on the first floor, and perform the hanging operation by manual operation. In this case, the distance between the yarn portion Ya on the upstream side and the yarn portion Yb on the downstream side is increased by the two yarn hooking portions 42 of the yarn dropping device 4, whereby it is also possible to prevent one yarn Y from being Both were caught by mistake.

2] In the above embodiment, the yarn lowering device 4 is moved up and down along the trailing side of the yarn passage YP at the time of yarn production, and the plurality of yarns Y are lowered to be more backward than the yarn passage YP of the first floor. The position of the side deviation. On the other hand, the position at which the plurality of yarns Y are lowered may be shifted to the front side with respect to the yarn passage YP, or may be shifted to the left and right.

In particular, in the above embodiment, the yarn hooking device 23 is moved toward the front side of the spinning and pulling device 1, and the yarn hooking device 23 is hooked from the front. In this case, if the yarn lowering device 4 is formed such that the plurality of yarns Y are lowered to a position which is more forwardly displaced than the yarn passage YP, the yarn hooking device 23 can easily take a plurality of yarns from the yarn lowering device 4. Y yarn Y. This is also the case when the operator takes the yarn Y from the front using the suction gun.

3] In the above embodiment, the yarn plucking member 45 is caused to swing the plurality of yarns Y close to the yarn holding portion 5, but the configuration is not limited thereto. For example, a plurality of yarns may be brought closer to each other by a linear motion as disclosed in Japanese Laid-Open Patent Publication No. 2013-57148 (FIG. 10).

In addition, the yarn plucking member is not an essential component. For example, when the plurality of yarns Y are lowered by the yarn lowering device 4 to a position shifted to the right side (the front side of the paper surface of the first drawing) with respect to the yarn passage YP at the time of yarn production, even if there is no dialing The yarn member 45 can also suck the plurality of yarns Y by the yarn holding portion 5. In other words, as shown in Fig. 3, the yarn holding portion 5 has a suction pipe 21 that advances and retracts in the left-right direction (a direction away from or close to the plurality of yarns Y), and a tip end portion provided at the suction pipe 21. The cutter 22 is. Even if the position at which the plurality of yarns Y are lowered is shifted to the right side with respect to the yarn passage YP, the plurality of yarns Y can be cut by moving the suction tube 21 to move the cutter 22 to the right. . The plurality of yarns Y cut by the cutter 22 are sucked by the suction pipe 21. Further, in this embodiment, the distal end portion of the suction tube 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 device that can be transported such as a suction gun. In a spinning and pulling device 1, when the operator finishes the work on the second floor and the downswing device 4 is lowered toward the first floor, and the transfer of the plurality of yarns Y to the yarn hooking device 23 or the yarn holding portion 5 is completed The yarn Y is separated from the yarn suction device 47 on the second floor (see Fig. 13 and Fig. 15). That is, at this moment, the yarn suction device 47 The mission is completed. Therefore, in the one spinning take-up device 1, when the yarn drop is completed, the yarn suction device 47 can be held by hand and moved to another place, and other work can be performed (for example, preparation of another spinning and pulling device 1) .

In the above-described embodiment, the yarn hooking device 23 cuts the yarn portion Ya on the upstream side of the yarn lowering device 4 for each of the plurality of yarns Y, and then receives the yarn Y. On the other hand, as shown in Fig. 16, the yarn hooking device 23 may cut the yarn Y between the two yarn hooking portions 42, and then take the yarn Y. In this case, it is also less likely that one yarn is erroneously cut at two places. Further, since the yarn Y between the two hooking portions 42 is close to the yarn hooking portion 42, the vibration can be suppressed, so that the success rate of the yarn cutting can be improved. Further, when the yarn Y is taken by the yarn holding portion 5 and the operator performs the yarn hooking using the yarn suction gun, the yarn Y can be cut between the two yarn hooking portions 42 in the same manner. The yarn is taken.

Further, by hooking each yarn to the two yarn hooking portions, the position of each yarn on the upstream side of the yarn lowering device 4, the position between the two yarn hooking portions 42, and the position on the downstream side of the yarn lowering device 4 can be made. These three positions are used to cut and transfer the yarn Y. Therefore, the capturing portion may be provided at a different portion depending on the size of the instrument used for the 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 front end portion of the yarn hooking arm 25 of the yarn hooking device 23. In this case, when the yarn Y is taken by the yarn holding portion 5 having a large size, the yarn portion Ya on the upstream side of the yarn dropping device 4 is cut as shown in Fig. 14 . The yarn Y is then taken. On the other hand, in the case where the yarn Y is taken by the yarn hanging device 23 having a small size, as shown in Fig. 16, the yarn Y is taken after the yarn Y is cut between the two yarn hooking portions 42. .

6] In the above embodiment, the two yarn hooking portions 42 of the yarn dropping device 4 are arranged at intervals in the front-rear direction, but the directions in which the two yarn hooking portions 42 are arranged (that is, the ratio yarn lowering device) 4, the direction in which the yarn portion on the upstream side is separated from the yarn portion on the downstream side) may be any direction that can intersect the up and down direction. For example, the two yarn hooking portions 42 may be arranged at intervals in the left-right direction.

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

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

9] The ascending detection sensor 48 and the down detection sensor 49 that detect the case where the lowering device 4 reaches the upper limit position and the lower limit position, respectively, are not essential members. For example, as the drive unit that moves the yarn drop device 4 up and down, if the motor capable of position control such as a servo motor is used, the inductors 48 and 49 are not required. Further, the operator can also manually stop the lowering device 4 while visually confirming the position of the lowering device 4, in which case no sensor is required. 48, 49.

10] The spinning and pulling device of the above-described embodiment is a device for producing POY in which the yarn Y spun from the spinning device 2 is directly drawn into the yarn P without being thinned, but it may be spun in the pair. After the yarn Y is drawn, it is taken up into a device for producing FDY of the yarn P. In the apparatus for producing FDY, the traction unit 6 is provided with a plurality of fine yarns Y disposed on the upstream side in the traveling direction of the rollers 15 and 16 in addition to the two yarn guide rollers 15 and 16.
