(Method of hanging yarn)

Next, in order to urge the automatic yarn hooking device 4 to the yarn guiding rollers 12, 13 A method of performing hooking by a plurality of fulcrum guides 21 will be described. Here, before the automatic yarn hooking device 4 is caused to perform the yarn hooking, the yarn suction portion 11 is sucked and held in advance by the plurality of yarns Y spun from the spinning device. Further, the second yarn guide roller 13 of the tractor unit 3 for hanging the yarn is placed at the yarn hooking position to be brought close to the first yarn guide roller 12. Further, the plurality of fulcrum guides 21 can be brought close to each other by being positioned at the above-mentioned hanging position. Further, in the yarn hook unit 33, the pressing roller 46 and the yarn dividing guide 47 are each in a retracting posture.

Further, when the automatic yarn hooking device 4 is caused to perform the yarn hooking, first, the automatic yarn hooking device 4 is moved to a position overlapping the pulling unit 3 to be hooked in the front-rear direction. Next, the robot arm 32 is driven, and the yarn hooking unit 33 is held such that the first direction is parallel to the front-rear direction, the second direction is parallel to the vertical direction, and the third direction is parallel to the left-right direction. The yarn holding portion 11 is closer to the upper side in the vertical direction. At this time, the tip end portion of the suction device 42 in the first direction faces the plurality of yarns Y. Next, the robot arm 32 is driven to move the yarn hooking unit 33 toward the front end side in the first direction. Thus, as shown in Fig. 7(a), a plurality of yarns Y will be hung on the yarn take-up guide 43. Further, in this state, the portion of the plurality of yarns Y between the yarn take-up guide 43 and the yarn holding portion 11 passes through a position that can be cut by the cutter 44.

Next, the suction device 42 is driven to attract and hold the plurality of yarns Y by the suction device 42. At this time, the plurality of yarns Y are converged by the yarn constricting guide 43, and thus are opposed to the front end portion of the suction device 42. The parts are arranged close to each other. Therefore, when the suction device 42 is driven, a plurality of yarns Y can be surely attracted.

Next, the cutters 44 are used to cut the plurality of yarns Y. Therefore, the yarn portion on the yarn holding portion 11 side among the plurality of cut yarns Y is sucked by the yarn holding portion 11. On the other hand, as shown in Fig. 7(b), the yarn portion of the plurality of yarns Y on the yarn converging guide 43 side is sucked and held by the suction device 42. Thereby, the plurality of yarns Y can be transferred from the yarn holding portion 11 to the suction device 42.

In the present embodiment, when the plurality of yarns Y are transferred from the yarn holding portion 11 to the suction device 42 as described above, the pressing roller 46 and the separation guide 47 are integrated. The retracted posture is located closer to the other side in the third direction than the suction device 42, the yarn converging guide 43, and the cutter 44. Therefore, when the yarn Y is transferred from the yarn holding portion 11 to the suction device 42, the pressing roller 46 and the yarn dividing guide 47 do not interfere with the yarn Y and interfere with the delivery of the yarn Y.

Next, the robot arm 32 is driven to move the yarn hooking unit 33, whereby the plurality of yarns Y held by the suction device 42 can be wound from the lower side in the vertical direction as shown in Fig. 8(a). Hanged on the first yarn guide roller 12. Next, as shown in FIG. 8(b), the plurality of yarns Y can be wound around the second yarn guide roller 13 from the upper side in the vertical direction.

Next, the robot arm 32 is driven so that the yarn hooking unit 33 is parallel to the vertical direction in the second direction and the first direction is inclined with respect to the front-rear direction, and is positioned below the plurality of fulcrum guides 21. Then, as the 9th As shown in (a) and (b) of FIG. 9, the pressing roller 46 is swung around the shaft 52, so that it can be switched from the retracted posture to the pressing posture. Then, the pressing roller 46 is pressed against the plurality of yarns Y, and is rotated by the frictional force with the plurality of yarns Y. As a result, the interval between the portions of the plurality of yarns Y pressed by the pressing roller 46 is enlarged. Further, the interval between the plurality of yarns Y is substantially the same as the interval between the openings of the plurality of grooves 47a of the yarn dividing guide 47.

Next, as shown in FIGS. 10(a) and 10(b), the sliding member 45 is caused to slide toward the distal end side in the first direction. Then, the pressing roller 46 pressed against the plurality of yarns Y slides together with the sliding member 45 toward the distal end side in the first direction, and is separated from the suction device 42. As a result, the inclination angle of the yarn Y that is inclined from the pressing roller 46 toward the suction device 42 toward the third direction when viewed from the second direction is changed as compared with the state of FIG. 9(a) and FIG. 9(b). small. Here, when the inclination angle of the yarn Y is large, the yarn Y is likely to be displaced from the position where the yarn Y is displaced from the pressing roller 46, which is a cause of the yarn swing. In particular, the more the outer side of the pressing roller 46 is located in the axial direction, the larger the inclination angle is, and the more likely the problem occurs. Therefore, in the present embodiment, as described above, the pressing roller 46 is separated from the suction device, whereby the above-described inclination angle of the yarn Y can be reduced, and the yarn swing can be suppressed.

Next, as shown in Figs. 11(a) and 11(b), the yarn splitting guide 47 is caused to swing around the shaft 71, so that the retracting posture can be switched to the hanging posture. Thereby, the plurality of grooves 47a of the yarn dividing guide 47 are separated from the plurality of yarns Y pressed by the pressing roller 46, respectively. Relative. Next, as shown in Fig. 12 (a) and Fig. 12 (b), the pressing roller 46 is caused to swing around the shaft 52, so that it is possible to return from the pressing posture to the retracting posture. Then, the pressing roller 46 is separated from the plurality of yarns Y, and the plurality of yarns Y are respectively inserted into the plurality of grooves 47a. At this time, as the distance from the opening of the plurality of grooves 47a is separated, the interval between the grooves 47a becomes larger, and thus the interval between the plurality of yarns Y inserted into the plurality of grooves 47a is further enlarged.

Here, as shown in Fig. 7(b), in a state where the plurality of yarns Y are sucked and held by the suction device 42, the interval of the plurality of yarns Y in the portion near the suction device 42 becomes small. Or it will be reversed and become one. Therefore, when it is maintained in this state, it is difficult to pull out the respective yarns Y from the plurality of yarns Y and insert them into the corresponding grooves 47a of the yarn dividing guides 47.

Therefore, in the present embodiment, the pressing roller 46 is pressed against the plurality of yarns Y sucked and held by the suction device 42. Thereby, the interval between the portions of the plurality of yarns Y pressed by the pressing roller 46 is increased, and the interval between the plurality of grooves Y is substantially the same as the interval between the plurality of grooves 47a. Then, after the yarn splitting guide 47 is placed in the yarn hooking posture, the pressing roller 46 is caused to return to the retracting posture, whereby the plurality of yarns Y can be inserted into the plurality of grooves 47a of the yarn dividing guide 47.

Next, as shown in Fig. 13 (a) and Fig. 13 (b), the sliding member 45 is slid toward the proximal end side in the first direction. Then, as shown in Fig. 14, the yarn dividing guide 47 slides together with the sliding member 45 toward the proximal end side in the first direction, and the plurality of yarns Y inserted into the plurality of grooves 47a are divided. Do not hang the yarn on the corresponding fulcrum guide 21. Here, as described above, in the state of FIGS. 9 to 13 , the first direction is inclined with respect to the front-rear direction, but in more detail, as shown in FIG. 14 , the first direction and the split yarn are set. The straight line connecting the groove 47a of the guide 47 and the front end opening of the groove 21a of the fulcrum guide 21 corresponding thereto is parallel. Then, after the yarn hooking of the plurality of fulcrum guides 21 is completed, the second yarn guiding roller 13 and the plurality of fulcrum guides 21 are moved to the winding position. Further, in the yarn hook unit 33, the yarn dividing guide 47 is swung around the shaft 71 to return it to the retracting posture.

In the present embodiment, the sliding member 45 is slid toward the distal end side in the first direction, whereby the pressing roller 46 is slid toward the distal end side in the first direction and away from the suction device 42. On the other hand, the sliding member 45 is slid toward the proximal end side in the first direction, whereby the plurality of yarns Y can be inserted into the base of the first direction of the yarn dividing guide 47 of the plurality of grooves 47a. The end side slides, and the plurality of fulcrum guides 21 respectively perform yarn hooking. In other words, in the present embodiment, the sliding member 45 is combined with the cylinder 51 for sliding the sliding member 45 in the first direction, and the roller sliding device and the guide sliding device of the present invention are also used.

Further, in the present embodiment, when the plurality of yarns Y are transferred from the yarn holding portion 11 to the suction device 42, the pressing roller 46 and the separation guide 47 are respectively retracted from each other so as not to be in contact with each other. Y yarn Y interferes. On the other hand, after the interval between the plurality of yarns Y is increased by the pressing roller 46, the separation guide 47 is switched from the retracted posture to the hanging posture, and the pressing roller 46 is returned to the retracted posture. A plurality of yarns Y can be inserted into the plurality of grooves 47a of the yarn dividing guides 47, respectively. In other words, in the present embodiment, the roller swinging device 53 that swings the pressing roller 46 and the guide swinging device 72 that swings the yarn separating guide 47 are combined as the relative moving device and the retracting device of the present invention. .

Next, a modification in which various modifications are applied to the present embodiment will be described.

In the above-described embodiment, the pressing roller 46 is pressed against the plurality of yarns Y at the stage of switching the pressing roller 46 from the retracted posture to the pressing posture, but the invention is not limited thereto. For example, the pressing roller 46 may be separated from the plurality of yarns Y at the stage of switching the pressing roller 46 from the retracted posture to the pressing posture, and then, when the pressing roller 46 is slid, the pressing roller 46 may be pressed in the middle thereof. Pressed on a plurality of yarns Y. In this case, while the pressing roller 46 is sliding, the pressing roller 46 is pressed against the plurality of yarns to widen the interval between the plurality of yarns Y, and the pressing roller 46 is separated from the suction device 42.

Further, in the above-described embodiment, after the sliding member 45 is combined with the cylinder 51 that drives the sliding member 45, the roller sliding device and the guide slider device of the present invention are also used, and the roller that swings the pressing roller 46 is swung. The device 53 is combined with the guide swinging device 72 that swings the yarn splitting guide 47, and also serves as the relative moving device and the retracting device of the present invention, but the roller sliding device, the guide sliding device, the relative moving device, and the retracting device are configured. The method is not limited to this.

For example, it is also possible to provide a sliding member with respect to the pressing roller 46 and the yarn dividing guide 47, respectively, and drive them with different pressure cylinders. These two sliding members. In this case, the sliding member to which the pressing roller 46 is attached is combined with the cylinder that drives the sliding member, and corresponds to the roller sliding device of the present invention. Further, the sliding member to which the yarn dividing guide 47 is attached is combined with the cylinder for driving the sliding member, and corresponds to the guide sliding device of the present invention.

In this case, the sliding member to which the pressing roller 46 is attached can be moved toward the proximal end side in the first direction from the same state as in FIGS. 11( a ) and 11 ( b ). Thereby, the pressing roller 46 is separated from the plurality of yarns Y, and the plurality of yarns Y are inserted into the plurality of grooves 47a of the yarn dividing guide 47. Further, in this case, the sliding member to which the pressing roller 46 is attached is combined with the cylinder for moving the sliding member, and then functions as a relative moving device of the present invention.

Further, in this case, the movable range of the sliding member to which the pressing roller 46 is attached and the sliding member to which the yarn separating guide 47 is attached can be further moved to the first direction than the sliding member 45 of the above-described embodiment. The base end side is lengthened, and the pressing roller 46 of the pressing posture and the yarn dividing guide 47 of the hanging posture can be moved to the proximal end side closer to the first direction than the distal end portion of the suction device 42. In this case, the pressing roller 46 in the pressing posture and the yarn dividing guide 47 in the hanging posture are moved closer to the proximal end side in the first direction than the distal end portion of the suction device 42, whereby the pressing roller 46 can be caused. And the yarn splitter 47 is retracted so as not to interfere with the yarn Y. Further, in this case, after the two sliding members respectively mounted with the pressing roller 46 and the separation guide and the pressure cylinder for moving the two sliding members are combined, it can also be used as the retracting device of the present invention. To make a difference.

Further, in this case, since the pressing roller 46 may be always parallel to the third direction, the roller swinging device 53 may not be provided, and the shaft 46a of the pressing roller 46 may be fixed to the sliding in a posture parallel to the third direction. Member 45. Similarly, in this case, the yarn splitting guide 47 may also extend in the third direction at all times, so that the yarn guiding guide 47 may not have the guide swinging device 72, and the yarn dividing guide 47 may extend in the third direction. The posture is fixed to the sliding member 45.

Further, in the above-described embodiment, after the pressing roller 46 is pressed against the plurality of yarns Y, the pressing roller 46 is moved toward the distal end side in the first direction, whereby the pressing roller 46 is separated from the suction device 42. However, it is not limited to this. After the pressing roller 46 is switched from the retracted posture to the pressing posture to enlarge the interval between the plurality of yarns Y, the yarn Y is inserted into the plurality of grooves 47a without sliding the pressing roller 46, and the fulcrum is turned toward the fulcrum. The yarn of the guide 21 is attached.

Further, in the above-described embodiment, when the plurality of yarns Y inserted into the plurality of grooves 47a are hooked to the plurality of fulcrum guides 21, the sliding member 45 is moved toward the proximal end side in the first direction. Thereby, the yarn dividing guide 47 is moved toward the proximal end side in the first direction, but the present invention is not limited thereto. For example, by driving the robot arm 32, the entire yarn hooking unit 33 may be moved toward the proximal end side in the first direction, and the yarn dividing guide 47 may be moved toward the proximal end side in the first direction. Further, in this case, the robot arm 32 corresponds to the guide slider of the present invention.

In addition, the roller slide device, the guide slide device, and the relative The moving device and the retracting device can also be realized by a configuration different from the configuration described above. Further, in this case, as the roller slide device, the guide slider device, the relative movement device, and the retraction device, four individual devices may be provided, or two or more of the four devices may be used as one device. s installation.

Further, in the above-described embodiment, the yarn take-up guide 43 is disposed below the suction device 42 in the second direction, and the cutter 44 is disposed below the yarn take-up guide 43 in the second direction. However, the yarn take-up guide 43 and the cutter 44 may be arranged in the opposite positional relationship.

Further, in the above embodiment, the cutter 44 is provided in the yarn hook unit 33, but the cutter 44 may not be provided in the yarn hook unit 33. For example, a cutter may be provided in the yarn holding portion 11. In this case, after the plurality of yarns Y held by the yarn holding portion 11 are sucked by the suction device 42, the yarns on the yarn holding portion 11 side are cut when the plurality of yarns Y are cut by the cutter. The line portion is attracted by the yarn holding portion 11, and the yarn Y portion on the suction device 42 side is sucked and held by the suction device.

Further, in the above embodiment, the yarn take-up guide 43 is provided in the yarn hook unit 33, but the yarn take-up guide 43 may not be provided. When the plurality of yarns Y are delivered from the yarn holding portion 11 toward the suction device 42, the position of the suction device 42 (the position of the suction device 42 in the state of Fig. 7(a)) does not leave the yarn holding portion 11 So far, even if there is no yarn converging guide 43, it is in contact with the suction device 42. The interval of the plurality of yarns Y in the opposite portion does not become so large. Therefore, even if the yarn constricting guide 43 is not provided, the suction device 42 can be driven to suck and hold the plurality of yarns Y by the suction device.

Further, in the above embodiment, the pressing roller 46 is a free roller that is rotatably supported by the shaft 46a, but the pressing roller 46 may be a driving roller that is rotationally driven by a motor. In this case, as shown in FIG. 9(a) and FIG. 9(b), when the pressing roller 46 is pressed against the plurality of yarns Y, the pressing roller 46 is rotationally driven, whereby the pressing roller 46 is used only by the pressing roller 46. The pressing roller 46 can be more stably rotated than the case where the friction between the yarn Y and the yarn Y is rotated. In this way, the interval between the portions of the plurality of yarns Y pressed by the pressing roller 46 can be stably expanded.

Further, in the above embodiment, the winding of the plurality of yarns Y toward the yarn guiding rollers 12, 13 and the hooking of the plurality of yarns Y toward the plurality of fulcrum guides 21 are all by the automatic yarn hooking device 4. Execution, but is not limited to this. For example, the operator may wind the plurality of yarns Y with respect to the yarn guide rollers 12 and 13, and then the automatic yarn hooking device 4 may be hooked to the plurality of fulcrum guides 21.

Further, in the above embodiment, the tractor unit 3 has two yarn guide rollers 12 and 13, but is not limited thereto. For example, as described in Japanese Laid-Open Patent Publication No. 2014-5555, the present invention has a plurality of yarn guide rollers (heating rollers) provided with a heater therein. In this case, it is also possible to perform yarn hooking to the plurality of yarn guide rollers by the yarn hooking robot.

Further, the above description has been made for the fulcrum guide 21 which becomes the fulcrum of the yarn Y when the yarn Y is traversed by the traverse guide 22 Examples of the yarn, but are not limited thereto. It is also possible to apply the present invention to the case of the yarn hooking of the yarn guide other than the fulcrum guide.
