Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tow (fiber bundle) take-up and storage device, and more specifically, it can store fibers, particularly synthetic fibers spun from a large number of spinnerets in a short time, reliably and safely. The present invention relates to a tow storage device.

[0002]

2. Description of the Related Art In melt spinning of general-purpose synthetic fibers such as polyester and polypropylene, a polymer is discharged from a plurality of spinnerets to form a large number of fiber bundles, so-called tows, and a rolling roll that rotates at high speed. It is generally stored in a storage container such as a can. Generally, the total fineness of tow is as thick as several thousand denier to tens of thousands denier in order to increase productivity.

As such a tow take-up and storage device, a take-up device having a number of take-up rolls corresponding to each spinneret, a guide roll device having a plurality of guide rolls, and A storage device provided with a pair of transfer rolls is used in which the storage device is arranged in order along the tow running main line (hereinafter, also referred to as a take-up direction). In the device in which such a series of device units are arranged, the guide roll improves the focusing property of the fibers spun from the plurality of spinnerets, and
By making the tow tension uniform, it has an important function of preventing it from being caught in the transfer roll. By the way, it is thought that the tow's focusing property is improved because the tows are alternately contacted to a plurality of guide rolls in the order of the back and the belly, so that the slack of the tow and the fluff of the single fiber are absorbed. There is. Therefore, it is said that the larger the number of the guide rolls within the economic range, the more preferable.

[0004] By the way, during the spinning start, when the fiber is taken up from the spinneret and the tow is taken up and stored, a yarn breakage occurred in a specific spinneret or a yarn when wound around the take-up roll. Re-start work and the like often occur when splicing work or when the tow is caught in the transfer roll. Such a start operation or a yarn splicing operation is performed when the whole spinning machine is stopped and then restarted, or when only the broken spinneret is spun without stopping the spinning machine. The worker temporarily winds the tow around the transfer assisting roll provided in the vicinity of the transfer roll by using a hand or an air sucker, and then manually hangs the thread on the guide roll by hand. Therefore, a great amount of recovery time is required for restarting and splicing, and a large amount of waste yarn is generated. Further, the threading is also dangerous because the threading is done by hand, and skill is required, and the threading failure often occurs due to rewinding around the guide roll.

On the other hand, in Japanese Patent Publication No. Sho 47-35603, the tow is pushed up from the bottom by a first guide around a winding drum provided on the upper part of a guide roller, and then the winding drum is moved leftward. There is disclosed a storing method and storing device for a tow which is moved to the first position, is pushed down by a second guide, and is then manually transferred or threaded on a plurality of guide rolls. However, with this device, thread hooking on the guide roll is a manual operation,
There is a problem that the tow can not be stored in a short time because the automatic threading is not possible and the transfer roll is a set.

Further, in Japanese Patent Laid-Open No. 3-199406, a tow with a broken thread is wound around a winding roll, and the roll is wound.
An automatic tow switching device is disclosed in which a roll sequentially moves in an upward, lateral, and downward directions across a transfer roll, and the yarn is automatically hooked on the transfer roll. This publication also discloses a device provided with two sets of transfer rolls capable of switching one set of transfer rolls to another transfer roll. According to the device, since there are two transfer rolls, the tow can be stored in a short time, but the thread hooking on the guide roll is a manual work, and the number of guide rolls can be increased. Can not. Therefore, when the thread is hooked on the guide roll, the storage operation is likely to fail due to the winding of the thread, which is dangerous.

[0007]
