摘要： Positional adjustment of a holding unit of a yarn threading mechanism is achieved with a small power. A spun yarn take-up machine 1 includes a yarn threading mechanism 21 configured to be able to perform yarn threading to fulcrum guides 20. The yarn threading mechanism 21 includes a holding unit 22 and a front-rear driving mechanism 45 having an air cylinder 57. The air cylinder 57 has a cylinder main body 66 and a piston rod 68 and is switchable between an actuated state and a non-actuated state. The front-rear driving mechanism 45 includes a rack 81, a pinion 82, and a transmission mechanism 83 including a movable body 99. When the holding unit 22 is moved from a predetermined position by a first distance D1, the transmission mechanism 83 moves the pinion 82 by a second distance D2 that is shorter than the first distance D1 toward a side identical with a side toward which the movable body 99 moves in the front-rear direction, by rotating the pinion 82 in accordance with the movement of the holding unit 22.

摘要： An object of the present invention is to efficiently apply oil to filaments in a structure in which the filaments are spun out downward from a single spinneret, divided into two groups, and bundled as two yarns.
A yarn production system 1 includes (i) a spinning apparatus 2 including a spinneret 24 provided with discharge ports 26, (ii) a cooler 4 provided below the spinneret 24, and (iii) an oiling unit 5 provided below the cooler 4. A virtual partitioning plane X divides the discharge ports 26 into a first discharge port group 26A and a second discharge port group 26B. The first discharge port group is arranged so that (i) discharge ports belonging to the first discharge port group form at least one first line extending in the front-rear direction (predetermined width direction) and at least one second line extending in a direction intersecting with the front-rear direction, (ii) one of the at least one first line has more discharge ports than the at least one first line, (iii) one of the at least one second line has more discharge ports than the at least one second line, and (iv) the one of the at least one first line is larger than the one of the at least one second line in terms of the number of the discharge ports, and the second discharge port group is arranged so that (i) discharge ports belonging to the second discharge port group form at least one first line extending in the front-rear direction (predetermined width direction) and at least one second line extending in the direction intersecting with the front-rear direction, (ii) one of the at least one first line has more discharge ports than the at least one first line, (iii) one of the at least one second line has more discharge ports than the at least one second line, and (iv) the one of the at least one first line is larger than the one of the at least one second line in terms of the number of the discharge ports. The oiling unit 5 includes a first oil supply surface 52a and a second oil supply surface 52b. When viewed in the up-down direction, an angle between a first width direction D1 and the virtual partitioning plane X is within the range of 45 to -45 degrees. When viewed in the up-down direction, an angle between a second width direction D2 and the virtual partitioning plane X is within the range of 45 to -45 degrees.

摘要： [Problem to be Solved] To provide a creel robot capable of achieving man-power savings while preventing a cap from being damaged and a system including the same.
[Solution to Problem] A yarn feeding package has a yarn-unwound paper tube 100 fitted with a cap 110 at an end thereof. The yarn-unwound paper tube 100 fitted with the cap 110 obtained after a yarn has been thoroughly unwound from the yarn feeding package is extracted from a peg shaft 36 of a creel stand 30 to be accommodated in a yarn-unwound paper tube accommodation box 84. The yarn-unwound paper tube 100 accommodated in the yarn-unwound paper tube accommodation box 84 is separated from the cap 110. The yarn-unwound paper tube 100 having been separated from the cap 100 is collected in a yarn-unwound paper tube collection box.

摘要： A package with a proper shape is obtained while formation of straight winding on a bobbin is prevented when yarn threading onto the bobbin is performed. A yarn threading apparatus 60 includes a yarn holding member 61, a yarn threading arm 62 having a yarn engagement portion 62a, a traverse guide 72, and a control unit 64. The yarn engagement portion 62a is arranged to be engaged with a yarn Y that is held by the yarn holding member 61 while the yarn threading arm 62 is moving from a standby position to a yarn threading position, and when the yarn threading arm 62 is at the yarn threading position, the yarn Y is disengaged from the yarn engagement portion 62a. The control unit 64 controls the traverse guide 72 to move to the outside of a predetermined traveling range M and controls the traverse guide 72 to catch the yarn Y disengaged from the yarn engagement portion 62a, and then controls the traverse guide 72 to perform reciprocal movement within the predetermined traveling range M. When the traverse guide 72 is performing reciprocal movement within the predetermined traveling range M and the yarn Y does not exist on a movement trace of the yarn threading arm 62 between the yarn threading position and the standby position, the control unit 64 moves the yarn threading arm 62 to the standby position.

摘要： Yarn threading from a yarn threading member to fulcrum guides is properly performed. A spun yarn take-up machine 1 is arranged so that, as a yarn threading member 30 is moved relative to fulcrum guides 20 while yarns Y sucked and held by a suction gun 80 are retained by the yarn threading member 30, yarn threading to the fulcrum guides 20 is performed. The spun yarn take-up machine 1 includes a yarn contact portion 51 which is positioned to be able to make contact with the yarns Y running between the yarn threading member 30 and the suction gun 80.

摘要： [Problem to be solved] To ensure stable and smooth unwinding of yarn from the yarn supply package.
[Solution] A drawing and false twisting machine 1 includes a peg 12 on which a yarn supply package 5 wound with yarn 3, which is POY, can be set; a processing position 35 where the yarn 3 from the yarn supply package 5 set on the peg 12 is processed to form a wind package; and a yarn guide that guides the yarn 3 toward the processing position 35 at a downstream end of a balloon formed by the yarn 3 unwound from the yarn supply package 5 set on the peg 12. The yarn supply cart 50 is a work robot that performs work for the drawing and false twisting machine 1. The yarn supply cart 50 includes a yarn supply package position adjustment device 57 that moves at least one of the yarn supply package 5 from which the yarn 3 is being unwound and the yarn guide 13 to decrease the distance between the yarn supply package 5 and the yarn guide 13 as the unwinding of the yarn 3 from the yarn supply package 5 progresses.

摘要： The number of rows of stocker pegs 26 provided by a stocker 20 is one greater than the number of rows of cart pegs 13 provided by a traveling creel cart 10. In a state in which one row of the stocker pegs 26 is bobbin-less and empty bobbins 6 are hung on all remaining rows of the stocker pegs 26, a first process and a second process are alternately performed under the control of a transfer control computer 40 to exchange empty bobbins 6 in the stocker 20 with full bobbins 5 in the traveling creel cart 10. In the first process, full bobbins 5 hung on one row of cart pegs 13 are moved to one row of stocker pegs 26, which are bobbin-less. In the second process, empty bobbins 6 hung on one row of stocker pegs 26 are moved to one row of cart pegs 13 where the full bobbins 5 has been removed in the first process. The traveling creel cart 10 conveys full bobbins 5 to the stocker 20 and replaces them with empty bobbins 6 in the stocker 20, and then conveys the empty bobbins 6.
