Description

  The present invention is a cheese pot that can accommodate the yarn supply cheese concentrically, and a yarn insertion passage that can be led out from the cheese pot by passing the yarn drawn upward from the yarn supply cheese downward. A double twisted yarn device configured to wind the yarn led out to the outside of the cheesepot while turning the outer peripheral side of the cheesepot and twist the yarn. .

The double-twisting device is a balloon that swirls the yarn that has passed through the yarn insertion path provided concentrically with the cheesepot and led out to the outside of the cheesepot on the outer peripheral side of the cheesepot, As the yarn is guided and wound up above the cheese pot, it has the advantage that it can be twisted twice each time the yarn is swirled around the cheese pot to efficiently twist the yarn. In the twisting device, wind is generated by a balloon formed on the outer peripheral side of the cheesepot.
In the conventional double twisting device, the yarn of the supplied cheese is fed through the upper opening of the cheesepot to the top of the cheesepot where the wind is generated, and then inserted downward into the yarn insertion passage. It is comprised so that it may derive | lead-out to the outer side of a pot (for example, refer patent document 1).
In addition, although it is not a technology related to the above-mentioned double twisting device, when the fiber is processed into a paper shape and twisted on the strand that has been cut into a tape shape, the tape shape A technique is known in which strands are impregnated with a liquid such as water and twisted (see, for example, Patent Document 2).

Therefore, in order to efficiently twist the yarn impregnated with the liquid, it is conceivable to use a double twisting device. However, in the conventional double twisting device, the fed cheese itself is placed in the space above the cheesepot. On the other hand, the yarn on the supplied cheese is easily dried over time as the yarn is fed, so that the yarn passes through the upper opening of the cheesepot and passes through the upper portion of the cheesepot. Since it is fed into the space where the wind is generated, the yarn is easily dried before entering the yarn insertion passage, and as a result, the liquid impregnated in the yarn evaporates and the yarn is impregnated with liquid. There is a drawback that unevenness is likely to occur in the state, and it is difficult to apply twist uniformly.
The present invention has been made in view of the above circumstances, and an object of the present invention is to enable efficient and even uniform twisting even with a yarn impregnated with a liquid.

  The first characteristic configuration of the present invention is a cheese pot that can accommodate the fed cheese in a concentric manner, and a strand that is drawn upward from the fed cheese, and can be led out to the outside of the cheese pot. A yarn insertion path is provided concentrically, and the yarn drawn out to the outside of the cheese pot is wound while turning the outer periphery of the cheese pot, and the yarn is twisted. In the double twisting device, the upper opening of the cheese pot is openable and closable, and the feed space of the yarn from the yarn supply cheese to the yarn insertion path is surrounded.

[Action and effect]
Since the top opening of the cheese pot is openable and closable, and the feed space from the yarn supply cheese to the yarn insertion passage is surrounded, the cheese supply itself is fed out through the top opening of the cheese pot. There is little possibility that the yarn will come into contact with the wind generated by the yarn turning on the outer peripheral side of the cheesepot.
As a result, even when twisting a yarn impregnated with liquid, it is difficult to dry until the yarn enters the yarn insertion path, and the evaporation of the liquid impregnated with the yarn is suppressed. As a result, unevenness in the liquid-impregnated state of the yarn is less likely to occur, and therefore the yarn impregnated with the liquid can be efficiently and evenly twisted.
The 2nd characteristic structure of this invention exists in the point which has formed the through-hole which can connect the inside and outside of the said feeding space in the said cover body.
[Action and effect]
If the yarn being swung around the outer periphery of the cheesepot is broken, the end of the broken yarn is swung around the outside of the cheesepot, and the yarn of the supplied cheese is blown by the balloon. It may be fed out of the cheesepot through the yarn insertion passage without forming.
In such a case, if the feeding space from the yarn supply cheese to the yarn insertion path is surrounded by a lid, feeding of the yarn from the yarn feeding cheese cannot be prevented from the outside of the lid. Since the through-hole that allows communication between the inside and outside of the feeding space is formed in the lid, even in such a case, it is inserted into the feeding space through the through-hole of the lid, for example, with a rod-shaped operation tool, It is possible to prevent the yarn from being fed out and to stop feeding the yarn through the yarn insertion path to the outside of the cheese pot.

  The 3rd characteristic structure of this invention exists in the point which provided the cover which encloses the turning space of the said yarn in the outer peripheral side of the said cheesepot.

[Action and effect]
Since the cover surrounding the swirling space of the yarn on the outer peripheral side of the cheesepot is provided, the wind generated by the yarn that swirls the outer periphery of the cheesepot in a balloon shape is difficult to escape to the outside, and therefore difficult to dry .
4th characteristic structure of this invention exists in the point which is provided in the inner bottom part of the said cheese pot with the saucer which can receive the said cheese in the state which surrounds the inner periphery side and outer periphery side over the perimeter. .
[Action and effect]
In the case of twisting a yarn impregnated with a liquid because a receiving tray is provided on the inner bottom portion of the cheese pot so as to be able to receive the fed cheese in a state surrounding the inner and outer circumferential sides of the cheese. In addition, even if liquid oozes from the yarn of the supplied cheese, the brewed liquid can be received by the receiving tray so that it does not adversely affect the operation of the apparatus, and the receiving tray receives the supplied cheese. The impregnating liquid can be stored to prevent the yarn from drying.
