Description

  The present invention relates to a yarn bundle loading apparatus and a yarn bundle loading method capable of automatically loading a yarn bundle into a yarn bundle container.

  Conventionally, with respect to the yarn bundle loading device and the yarn bundle loading method, as shown in FIG. 9, a yarn bundle 32 in which a yarn bundle is wound in advance with a winding frame and both ends are fixed with a tape 31 or the like, A method is generally known in which a film 33 or the like is wound, the periphery is squeezed with a wire 35, and the yarn bundle container 30 is pushed out and loaded (for example, see Patent Document 1).

  However, such a method requires a step of winding the tape 31 around both ends of the yarn bundle 32 in advance, and the manufacturing equipment becomes complicated. Further, when the yarn bundle 32 is pushed out into the yarn bundle container 30, a part of the yarn is buckled and the quality is deteriorated. Further, the tape 31 is stuck in the yarn bundle container 30 and remains as a foreign substance, and the product to be produced. There was a problem such as greatly reducing the yield of.

  On the other hand, as shown in FIG. 10, a part of the yarn bundle 41 wound in a circular shape around the winding ring 36 is cut out, and a plurality of arranged yarn bundle cases 38 are indirectly used with a magnet 39. A method is also known in which the clamping tool 37 is passed while transmitting power, and thereafter the tip of the yarn bundle 41 is grasped by the clamping tool 37 and the yarn bundle 41 is loaded into the yarn bundle case 38 while being pulled by the wire 40. (For example, refer to Patent Document 2).

  Since this method does not use tape, the problem of foreign matter due to tape can be solved. However, since the power transmission to the clamp tool is a magnet provided outside the yarn bundle container, the center of the clamp tool and yarn bundle container is used. When the axis is displaced and the clamp tool passes, it touches the inside of the yarn bundle container and damages the inside of the yarn bundle container to generate foreign matter, or the loaded yarn bundle is damaged by the damage in the yarn bundle container. There was a serious problem.

Also, when the yarn bundle wound in a circular shape is taken out, there is a difference in the length of the yarn inside and outside the winding frame, so the yarn bundle loaded in the yarn bundle container is bent and the yarn is bent. There was also the problem that the quality would vary.
