Problems solved by technology

[0004] However, as from Patent Document 1 Figure 4 As can be seen, the air flow of the cooling air around each cooling cylinder varies greatly due to different cooling cylinders
Therefore, there is a concern that the flow rate of the cooling air supplied to the yarn walking space differs greatly among different cooling cylinders
Also, even if only one cooling cylinder is observed, the cooling air flow around it varies greatly in the circumferential direction
Therefore, there is a possibility that the cooling air around the cooling cylinder tends to generate eddies, and the flow rate of the cooling air supplied to one yarn running space may vary greatly in the circumferential direction.
As a result, in the conventional yarn cooling device, due to uneven cooling, there is a problem that the quality of the produced yarn tends to vary.

Embodiment Construction

[0028] Embodiments of the yarn cooling device of the present invention will be described below.

[0029] [Melt spinning device]

[0030] figure 1 It is a partial sectional view of a melt spinning device equipped with the yarn cooling device of the present invention. Such as figure 1 As shown, the melt spinning device 1 includes a spinning beam 2, a yarn cooling device 3, an oil feeding device 4, and the like. The spinning beam 2 includes a plurality of unit housings 11 . The spin pack 12 is arranged in each pack case 11, and the melted material that becomes the yarn Y such as molten polyester is stored in the spin pack 12. A spinneret 13 is provided at the lower end of the spinneret 12, and the molten material stored in the spinneret 12 is formed as a plurality of yarns Y from a plurality of through holes not shown in the spinneret 13. Spun out to the bottom. Among them, the plurality of spinnerets 13 are arranged in two rows in a staggered manner along the left and ri...

Abstract

The qualities of yarns are uniformized. For each of cooling cylinders 30, a partition 51 is provided to surround each cooling cylinder 30 and form a circulation space 52 between the partition 51 and the outer circumferential surface of the cooling cylinder 30 to allow cooling wind to circulate in the circulation space 52, and at a border part between a supply space 23 to which the cooling wind is supplied from the outside and the circulation space 52, a flow adjustment plate 53 is provided to circulate the cooling wind from the supply space 23 into the circulation space 52 while adjusting the flow of the cooling wind.

Description

technical field [0001] The present invention relates to a yarn cooling device for cooling yarn spun from a spin beam that spins molten material as yarn from a plurality of spinnerets to below. Background technique [0002] As a yarn cooling device for cooling the yarn spun from the spinning beam, there is a device disclosed in Patent Document 1, for example. In this yarn cooling device, a plurality of cooling cylinders are accommodated in a cooling air supply box, and the yarn is cooled by supplying cooling air to a yarn running space inside the cooling cylinder. Since one cooling air supply box is provided for a plurality of cooling cylinders, the number of ducts for supplying cooling air can be reduced. Therefore, the cooling cylinders can be arranged at a high density, and the production efficiency of the yarn can be improved. [0003] [Patent Document 1] Japanese Unexamined Patent Publication No. 2011-252260 [0004] However, as from Patent Document 1 Figure 4 As can...
