Description

  The present invention relates to a winding tube used in a yarn winding device of a false twisting machine, a plurality of packages formed on the winding tube, and a method of manufacturing a plurality of packages.

  The yarn winding device described in Patent Document 1 is a yarn winding device that winds a plurality of yarns in a false twisting machine. One winding tube is rotatably held in the cradle. The supplied plurality of yarns may not be combined, but may be wound as they are on the winding tube apart from each other to form a plurality of packages. The winding tube in which two packages are formed by the yarn winding device is cut at substantially the center in the longitudinal direction to form two separate packages, which are used in the subsequent process (see Patent Document 1, paragraph 0046).

  Forming a plurality of packages on one winding tube has an advantage of improving the productivity of the package. In addition, there is also an advantage that when the yarn is unwound from each package in a subsequent process, the unwinding property of the yarn is improved. The unwinding property of the yarn of each package is improved because the winding width of each package becomes narrower when a plurality of packages are formed on one winding tube. For example, when one package is formed on one winding tube, the winding width is 250 mm, the maximum package weight is 6 kg, and the winding width is widened. If the winding width is wide, the unwinding tension becomes high, and the yarn may be easily broken during unwinding. On the other hand, when two packages are formed in one winding tube, for example, the winding width of each package is 110 mm and the maximum package weight is 2 kg, and the winding width of each package is narrowed. If the winding width is narrow, the unwinding tension will be low, and the yarn will not break easily during unwinding.

  However, if a plurality of packages are formed in one winding tube and divided into individual packages, the number of yarns in each package is small, so the number of package replacements increases when used in a later process. As a result, the operation efficiency of the post-process decreases.

  Therefore, if the yarns of a plurality of packages formed on one winding tube can be connected and continuously unwound, the yarn amount is sufficiently large and the unwinding property is good, and the winding tube Therefore, it is considered that a package that can be easily handled can be formed. As a technique for connecting a plurality of package yarns, although not a yarn winding device in a false twisting machine, for example, the technologies described in Patent Documents 2 and 3 are known.

  Among these, as described in Patent Document 2, it is necessary to form a tail yarn in order to connect a plurality of package yarns formed in one winding tube. For this reason, it is necessary to secure in advance a yarn to be a tail yarn at the beginning of winding of the package. A plurality of package yarns can be connected by bundling and connecting the winding end yarn end of the next package adjacent to the tail yarn after the package formation.

  In Patent Document 2, in order to secure a yarn as a tail yarn in advance, the package starts after the thread start thread end is passed through the threading hole formed in the winding pipe and the winding start thread end is fixed to the winding pipe. Has begun to form. This pre-preparation work before the package formation is predicated on manual work by the operator, and the work takes a long time. For this reason, for example, when a fully packaged package is doffed and replaced with a new take-up tube, although not explicitly disclosed in Patent Document 2, the yarn supply is temporarily stopped and preliminary preparation work is performed. It is thought that it is necessary to do. When the preparatory work is completed and a new winding tube is attached, the yarn supply is resumed and the formation of the package is resumed. Patent Document 3 does not disclose pre-preparation work before package formation.

  The winding drum 23 is disposed so as to be in close contact with the outer peripheral surface of the winding tube 19 held by the cradle 20. The take-up drum 23 is rotated by a motor (not shown). When the take-up drum 23 is rotated, the take-up tube 19 that is in close contact with the take-up drum 23 is rotated.

  The above is the configuration of the drawing false twisting machine 1000 and the false twisting weight 100. Next, in the false twisting weight 100, two yarns Ya and Yb are wound around one winding tube 19 to form two packages P (first package P1 and second package P2). explain.

  The false twisting weight 100 on the left side of FIG. 2 and the two yarns Ya and Yb sent from the yarn supply packages 11a and 11b are respectively connected to pipes 12a and 12b and a first feed roller, as shown in FIG. 6a, 6b, primary heater 13, cooling devices 14a, 14b, false twisting devices 15a, 15b, upstream second feed rollers 7a, 7b, interlace nozzles 16a, 16b, and downstream second feed. It is sent to the winding device 18 through the rollers 8a and 8b, the secondary heaters 17a and 17b, and the third feed rollers 9a and 9b.

  Specifically, the yarn feed speed of the upstream second feed rollers 7a and 7b is set to be higher than the yarn feed speed of the first feed rollers 6a and 6b. As a result, the yarns Ya and Yb are stretched between the first feed rollers 6a and 6b and the upstream second feed rollers 7a and 7b. In this state, the false feed devices 15a and 15b use the first feed rollers 6a and 6b. 6b and the upstream second feed rollers 7a, 7b. The yarns Ya and Yb twisted while being stretched are heat-set by the primary heater 13 and then cooled by the cooling devices 14a and 14b. The twisted and heat-set and cooled yarns Ya and Yb are untwisted after passing through the false twisting devices 15a and 15b until reaching the upstream second feed rollers 7a and 7b.

  The yarn feed speed of the downstream second feed rollers 8a and 8b is set to be different from the yarn feed speed of the third feed rollers 9a and 9b. As a result, the yarns Ya and Yb are relaxed between the downstream second feed rollers 8a and 8b and the third feed rollers 9a and 9b, and in this state, the yarns Ya and Yb are moved in the secondary heaters 17a and 17b. It is subjected to relaxation heat treatment and sent to the third feed rollers 9a and 9b. Here, the ratio of the yarn feed speed between the downstream side second feed rollers 8a, 8b and the third feed rollers 9a, 9b is set according to the form of the yarns Ya, Yb.

  The two yarns Ya and Yb fed from the third feed rollers 9a and 9b pass through the yarn guides 30a and 30b, respectively, and are parallel to the axis of the single winding tube 19 by the reciprocating travel of the belt body 26. While being traversed by the reciprocating traverse guides 27a and 27b, each of the two packages P (the first package) is wound around the one winding tube 19 that abuts the rotating winding drum 23 and rotates. P1, a second package P2) is formed.

  The above is a description of a state in which two packages P (first package P1 and second package P2) are formed. Next, after one new winding tube 19 is supplied to the false twisting weight 100, two packages P (first package P1, second package P2) are formed, and two packages P (first package P1) are formed. A process until the yarns Ya and Yb of the package P1 and the second package P2) are connected will be described.
