  • An object of the present invention is to uniformize the qualities of yarns in a yarn cooler which is provided with plural cooling cylinders for cooling the yarns.
  • the present invention provides a yarn cooler for cooling yarns spun out from a spinning beam which is configured to spin out, as the yarns, a molten material downward through spinnerets, which includes: cooling cylinders which are provided below the spinning beam to oppose the respective spinnerets and each of which includes a first yarn running space in which the yarns run, a peripheral wall of the first yarn running space including a flow control member which is arranged to adjust the flow of cooling wind flowing into the first yarn running space; partitioning cylinders which are connected with lower end portions of the respective cooling cylinders and each of which includes a second yarn running space communicating with the first yarn running space, a peripheral wall of the second yarn running space including a shielding member which is arranged to block the cooling wind from flowing into the second yarn running space; a quench box which includes a supply space to which the cooling wind is supplied from outside, the partitioning cylinders being provided in the supply space, wherein, the cooling cylinders are provided outside the supply space and a partition is provided for

  • the partition is a regular hexagon in shape in plan view.
  • the cooling cylinders are disposed in a staggered manner in plan view.
  • the cooling cylinders are densely disposed as the cooling cylinders are disposed in a staggered manner, and hence the efficiency in the production of the yarns is improved.
  • the quench box includes a side wall which surrounds the cooling cylinders.
  • the side wall prevents the cooling cylinder from being exposed to the outside and protects the cooling cylinder. Furthermore, with the side wall, the strength of the quench box is improved.

  • the yarns Y spun out from the spinneret 13 run downward in the first yarn running space 31.
  • a peripheral wall of the first yarn running space 31, i.e., a cylinder body of each cooling cylinder 30 is formed of a first flow control member 32 and a second flow control member 33 which is provided inside the first flow control member 32.
  • the first flow control member 32 is formed of, for example, perforated metal, and adjusts the flow of the cooling wind so that the cooling wind flows substantially horizontally from a later-described circulation space 52 into the first yarn running space 31.
  • the second flow control member 33 is formed of, for example, a multi-layer metal wire mesh and uniformizes the flow of the cooling wind flowing from the later-described circulation space 52 into the first yarn running space 31.

  • the cooling cylinders 30 are disposed in two dimensions, a direction in which the number of the cooling cylinders 30 is largest is considered as the arrangement direction.
  • the cooling wind meanders through these partitioning cylinders 40.
  • the flow of the cooling wind around each partitioning cylinder 40 is different between the partitioning cylinders 40. This, however, is not particularly problematic because the cooling wind does not flow from the supply space 23 into the second yarn running space 41 inside the partitioning cylinder 40.
  • the cooling wind flowing in the supply space 23 then flows into each circulation space 52.
  • the flow adjustment plate 53 is provided between the supply space 23 and each circulation space 52.

  • the circulation spaces 52 are all identical in shape, variations in the flow rates of the cooling wind flowing into the respective circulation spaces 52 are further restrained.
  • the cooling wind adjusted by the flow adjustment plate 53 flows mainly upward in the circulation space 52 and at the same time flows into the first yarn running space 31 from the entire circumference of the cooling cylinder 30.

  • the yarns Y running in the first yarn running space 31 are cooled.
  • the flow adjustment plate 53 is provided at the border part between the supply space 23 and the circulation space 52, the variations in the flow rates of the cooling wind supplied from the supply space 23 to the respective circulation spaces 52 are restrained, and the variations in the flow rates of the cooling wind supplied from the circulation spaces 52 to the first yarn running spaces 31 are also restrained. Furthermore, because the circulation space 52 is surrounded by the partition 51, the cooling wind does not flow into the circulation space 52 from around the circulation space 52, and hence the generation of a swirl of the cooling wind is restrained in the circulation space 52.
  • the flow rate of the cooling wind flowing in the circulation space 52 is more or less uniformized in the circumferential direction
  • the flow rate of the cooling wind supplied from the circulation space 52 to the first yarn running space 31 is more or less uniformized in the circumferential direction.
  • the variations in the flow rate of the cooling wind supplied to the first yarn running space 31 is restrained and irregular cooling is restrained not only between the cooling cylinders 30 but also in the circumferential direction in one cooling cylinder 30, the qualities of the yarns Y are uniformized.
  • the circulation space 52 is plane-symmetric to at least one plane P which includes the center axis of the cooling cylinder 30.
  • the circulation space 52 is plane-symmetric to at least one plane P which includes the center axis of the cooling cylinder 30 in this manner, the flow of the cooling wind in the circulation space 52 is more or less plane-symmetric, too, and the flow rate of the cooling wind flowing in the circulation space 52 is further uniformized in the circumferential direction.
  • the variations in the flow rate of the cooling wind supplied to the first yarn running space 31 are further restrained.
  • the circulation space 52 is plane-symmetric to two planes P which include the center axis of the cooling cylinder 30 and are orthogonal to each other.
  • the circulation space 52 is plane-symmetric to two planes P which include the center axis of the cooling cylinder 30 and are orthogonal to each other in this way, the flow of the cooling wind in the circulation space 52 is more or less plane-symmetric to the two orthogonal planes P, and hence the flow rate of the cooling wind flowing in the circulation space 52 is further uniformized in the circumferential direction. Therefore, in the circumferential direction of one cooling cylinder 30, variations in the flow rate of the cooling wind supplied to the first yarn running space 31 are further effectively restrained.
  • FIG. 6 is a schematic view for comparison between shapes of partitions.
  • the section a shows a case where partitions 61 which are rectangular in plan view are provided, whereas the section b shows partitions 71 which are circular in plan view are provided.
  • Coolers are typically required to have a larger circulation space 52 and a higher flow rate of cooling wind in order to improve the efficiency in the cooling of the yarns Y.
  • partitions 61 (indicated by thick lines) which are rectangular in plan viewed are typically employed.
  • the circulation space 62 is enlarged by the hatched areas in the figure, as compared to the circulation space 52 of the present embodiment.
  • the shape of the circulation space 62 is irregular in the circumferential direction, and the cooling wind tends to swirl in the circulation space 62.
  • partitions 71 (indicated by thick lines) which are circular in plan view are typically employed.
  • the circulation space 72 is narrowed by the hatched areas in the figure, as compared to the circulation space 52 of the present embodiment.
  • the hatched gaps are formed between the partitions 71. Such gaps are redundant spaces.
  • the partition 51 is arranged to form a regular hexagon in plan view as in the present embodiment, the enlargement of the circulation space 52 and the uniformization of the flow of the cooling wind in the circumferential direction in the circulation space 52 are both achieved with proper balance.
  • the cooling cylinders 30 are staggered, redundant gaps are not formed around the partitions 51, and the circulation space 52 is maximized.
  • the side walls (the side walls of the cooling cylinder housing chamber 22) surrounding the cooling cylinder 30 are provided in the quench box 20. This prevents the cooling cylinder 30 from being exposed to the outside and protects the cooling cylinder 30. Furthermore, with the side walls, the strength of the quench box 20 is improved.
  • the cooling cylinders 30 are lined up in the arrangement direction (left-right direction), and the cooling wind is supplied from the supply space 23 in the direction orthogonal to the arrangement direction. Because the cooling wind supplied in the direction orthogonal to the arrangement direction is likely to uniformly flow around the cooling cylinders 30 lined up in the arrangement direction, the variations between the flow rates of the cooling wind supplied to the first yarn running spaces 31 of the cooling cylinders 30 are further restrained.
  • the cooling cylinders 30 may be disposed in a different manner.
  • the cooling cylinders 30 may be lined up in the left-right direction to form a single row, or the cooling cylinders 30 may be arranged to form plural rows but not in a staggered manner.
  • arranging the partition 51 to form a regular hexagon in plan view is the most preferable. This, however, does not exclude cases where the partition 51 form a shape which is not a regular hexagon. For example, even when the partitions 61 and 71 which form rectangular and circular shapes as shown in FIG. 6 are employed, the qualities of the yarns Y are uniformized as compared to the known technologies, because one circulation space 52 is provided for one cooling cylinder 30.
  • the circulation space 52 is plane-symmetric to two planes which include the center axis of the cooling cylinder 30 and are orthogonal to each other.
  • the cooling cylinder housing chamber 22 is provided in the quench box 20 and the cooling cylinders 30 are surrounded by the side walls of the cooling cylinder housing chamber 22. This arrangement, however, is not prerequisite. The side walls may not be provided and the outer circumferential parts of the partitions 51 may be exposed to the outside.
  • each cooling cylinder 30 is formed of the first flow control member 32 and the second flow control member 33
  • the second flow control member 33 may be omitted.
  • the cooling wind is uniformly and suitably supplied to the yarns Y even if the second flow control member 33 is not provided, when the distance between the outermost peripheral part of the yarns Y running in the first yarn running space 31 and the first flow control member 32 is arranged to be 12 to 15 times as long as the hole diameter of the perforated metal constituting the first flow control member 32.
