Summary of the Invention

Problems to be Solved by the Invention

[0005] In recent years, the number of yarns that can be spun at one time by a spinning device has been increasingly increasing. In such a situation, if the above-described upper hood and lower hood are provided corresponding to each yarn, the number of necessary members increases, and there arises a problem of an increase in the cost of the spinning equipment.

[0006] An object of the present invention is to enable the length in the vertical direction of a slow cooling space to be changed with a small number of members even when the number of spun yarns is large.

Means for Solving the Problems

[0007] A spinning facility according to a first invention includes a spinning device having a plurality of spinning nozzles for spinning yarns respectively, a cooling device disposed below the spinning device and configured to cool the plurality of yarns respectively spun from the plurality of spinning nozzles, and a slow cooling section disposed between the spinning device and the cooling device in the vertical direction. The cooling device has a plurality of cooling cylinders extending in the vertical direction and arranged to surround the plurality of yarns respectively, and configured to guide cooling air to the plurality of yarns. The slow cooling section has a plurality of surrounding surfaces configured to surround at least a part of the plurality of cooling cylinders in the vertical direction, and a block member that forms a plurality of slow cooling spaces for slowly cooling the plurality of yarns respectively by a portion above the plurality of cooling cylinders among the plurality of surrounding surfaces, and an adjustment section configured to be able to adjust a relative position in the vertical direction between the block member and the plurality of cooling cylinders.

[0008] In the present invention, a single block member can surround a plurality of cooling cylinders. Further, by adjusting the relative position in the vertical direction between the block member and the plurality of cooling cylinders by the adjusting unit, the distance in the vertical direction between the spinneret and the cooling device (that is, the length in the vertical direction of the slow cooling space) can be changed. Therefore, even when the number of yarns that can be spun in the spinning facility is large, the length in the vertical direction of the slow cooling space can be changed with a small number of members.

[0009] The spinning facility of the second invention is characterized in that, in the first invention, it includes a seal member disposed so as to be sandwiched in the vertical direction between the spinning device and the block member.

[0010] When the temperature of the spinneret fluctuates, the quality of the yarn may deteriorate. In the present invention, the seal member can surely suppress the intrusion of outside air from the gap between the spinning device and the block member into the slow cooling space. For this reason, temperature fluctuations of the spinneret due to outside air can be suppressed.

[0011] The spinning facility of the third invention is characterized in that, in the second invention, the seal member is a heat insulating member.

[0012] In the present invention, heat transfer between the spinning device and the block member can be suppressed. Thereby, temperature fluctuations of the spinneret can be further suppressed.

[0013] The spinning facility of the fourth invention is characterized in that, in any one of the first to third inventions, the cooling device is provided with a moving mechanism configured to move between a first position when the plurality of yarns are spun from the spinning device and a second position below the first position, and when the cooling device is located at the second position, a working space is formed in the vertical direction between the spinning device and the cooling device, in which operations on the plurality of spinnerets, the plurality of cooling cylinders, and the adjusting unit can be performed.

[0014] In the present invention, by moving the cooling device to the second position, operations on the spinneret, the cooling cylinder, and the adjustment unit can be performed in the working space. Therefore, good workability can be ensured.

[0015] The spinning facility according to the fifth invention is characterized in that, in the fourth invention, the block member is configured to move integrally with the cooling device when the moving mechanism operates.

[0016] When the cooling device moves to the second position, if the block member moves relative to the cooling device, the block member and the plurality of cooling cylinders will be temporarily separated. Therefore, when moving the cooling device from the second position to the first position, it is necessary to align the plurality of surrounding surfaces and the plurality of cooling cylinders, which may be time-consuming. In the present invention, when moving the cooling device, the state where the plurality of surrounding surfaces respectively surround the plurality of cooling cylinders can be maintained. Therefore, the need for the above alignment can be avoided.

[0017] The spinning facility according to the sixth invention is characterized in that, in the fifth invention, the adjustment unit has one or more mounting portions configured such that the block member is placed thereon and configured to be movable in the vertical direction with respect to the cooling device.

[0018] In the present invention, the block member can be easily removed from the mounting portion as needed.

[0019] The spinning facility according to the seventh invention is characterized in that, in the sixth invention, the adjustment unit has one or more bolts extending in the vertical direction that respectively support the one or more mounting portions, and the mounting portions are configured to be moved in the vertical direction by rotating the one or more bolts.

[0020] In the present invention, the position of the mounting portion in the vertical direction can be precisely adjusted by a simple structure using bolts. In other words, the relative position between the block member and the plurality of cooling cylinders can be precisely adjusted by a simple structure.

[0021] The spinning equipment of the eighth invention, in the seventh invention, comprises a base portion with the above-mentioned one or more bolts screwed therein, and the above-mentioned one or more bolts are configured to be movable in the vertical direction relative to the base portion by rotation, and the above-mentioned one or more mounting portions are integrally movable in the vertical direction with the above-mentioned one or more bolts respectively. of the bo It is characterized in that.

[0022] In the present invention, the mounting portion can be moved in the vertical direction with a simple structure.

[0023] The spinning equipment of the ninth invention, in the eighth invention, the above-mentioned one or more mounting portions have one or more nuts each having a mounting surface in contact with the block member, and the above-mentioned one or more nuts are fixed to the above-mentioned one or more bolts respectively. of the bo It is characterized in that.

[0024] In the present invention, the mounting portion can be formed using generally inexpensive nuts. Therefore, the cost of the members can be reduced.

[0025] The spinning equipment of the tenth invention, in any one of the seventh to ninth inventions, the block member has one or more working holes for performing operations on the above-mentioned one or more bolts in a state where the block member is placed on the above-mentioned one or more mounting portions.

[0026] In the present invention, with the block member placed on the mounting portion, a tool for turning the bolt can be passed through the working hole to access the bolt with the tool. Therefore, the bolt can be rotated with the block member remaining placed on the mounting portion. That is, when rotating the bolt, there is no need to move the block member away from the mounting portion. Therefore, the labor for manually adjusting the relative position between the block member and the cooling cylinder can be reduced.

[0027] The spinning equipment of the eleventh invention, in any one of the sixth to tenth inventions, the adjusting portion is characterized by having a plurality of mounting portions as the above-mentioned one or more mounting portions.

[0028] In a configuration where only one placement part is provided, depending on the size relationship between the placement part and the block member, the block member may lose its balance and tilt in the horizontal direction. In such a case, for example, there is a possibility that the block member abuts against the cooling cylinder, causing an obstacle to the operation for adjusting the relative position between the block member and the cooling cylinder. In this regard, in the present invention, the block member is placed on a plurality of placement parts. Therefore, the balance of the block member can be maintained well.

[0029] The spinning equipment of the 12th invention is, in any one of the 5th to 11th inventions, each of the plurality of cooling cylinders has a filter member detachable from the cooling device and a pressing member configured to press the filter member from above, and the pressing member is configured to be able to change its state between a pressing state in which the filter member is pressed from above when the cooling device is in the second position and a release state in which the pressing state is released and the filter member can be lifted.

[0030] In a configuration where the block member can move integrally with the cooling device, depending on the positional relationship between the pressing member and the block member, when removing the filter member from the cooling device, it may be necessary to move the block member relative to the cooling device. In the present invention, by changing the state of the pressing member from the pressing state to the release state, the filter member can be lifted and removed from the cooling device without moving the block member relative to the cooling device.

[0031] The spinning equipment of the 13th invention is, in the 12th invention, the record press pressing the material is part, and is characterized by being a ring member detachable from the upper surface of the plurality of cooling cylinders each of .

[0032] In the present invention, the filter member can be pressed from above by a pressing member with a simple structure, and the filter member can be made removable from the cooling device.

[0033] The spinning equipment of the 14th invention, in any one of the 1st to 13th inventions, wherein the plurality of cooling cylinders each have a plurality of extending portions extending downward from the lower surface of the block member, and are configured to be movable at least in the vertical direction with respect to the plurality of extending portions, and one or more covering members that cover a plurality of gaps formed between the plurality of cooling cylinders and the plurality of surrounding surfaces.

[0034] If the gap between the surrounding surface of the block member and the outer peripheral surface of the cooling cylinder is large, outside air is likely to flow into the slow cooling space, which may have an adverse effect on the yarn quality. For this reason, it is preferable that the gap is as small as possible. However, if the gap is too small, when adjusting the relative position in the vertical direction between the block member and the cooling cylinder, the block member, the surrounding surface, and the outer peripheral surface of the cooling cylinder are likely to come into contact. For this reason, the block member and the cooling cylinder may not be able to move relative to each other, and the adjustment operation may become difficult. In the present invention, when the yarn is produced, the covering member can cover the gap between the surrounding surface of the block member and the outer peripheral surface of the cooling cylinder. Therefore, even when the gap is large, it is possible to prevent outside air from flowing into the slow cooling space. Therefore, it is possible to achieve both ease of adjusting the position of the block member and good yarn quality.

[0035] The spinning equipment of the 15th invention, in the 14th invention, wherein the one or more covering members are configured to be detachable with respect to the plurality of extending portions.

[0036] In the present invention, when the relative position between the surrounding surface of the block member and the cooling cylinder is adjusted, it is possible to prevent the covering member from getting in the way.

Embodiments for Carrying Out the Invention

[0038] Next, embodiments of the present invention will be described. For convenience of explanation, the directions shown in FIG. 1 are taken as the vertical direction and the front-rear direction. The vertical direction (the vertical direction of the paper surface of FIG. 1) is the vertical direction in which gravity acts. The front-rear direction (the left-right direction of the paper surface of FIG. 1) is a direction orthogonal to the vertical direction. The direction orthogonal to both the vertical direction and the front-rear direction (the direction perpendicular to the paper surface of FIG. 1) is taken as the left-right direction.

[0039] (Spinning Equipment) The outline of the spinning equipment 1 according to this embodiment will be described with reference to the schematic diagram of FIG. 1. The spinning equipment 1 is equipment for generating a yarn Y made of synthetic fiber. The spinning equipment 1 includes a spinning device 2, a cooling device 3, a slow cooling part 4, and an oil application part 5.

[0040] The spinning device 2 is a melt spinning device configured to spin a plurality of yarns Y made of molten polymer. The spinning device 2 includes a frame 10 having a substantially rectangular parallelepiped shape, a plurality of pack housings 11 formed in the frame 10, and a plurality of spinning packs 12 respectively mounted on the plurality of pack housings 11. The plurality of spinning packs 12 are arranged in a zigzag pattern, for example, along the left-right direction (not shown in the figure. For the arrangement in the horizontal direction, refer to the cooling cylinder 21 and the first through hole 31 described later and shown in FIG. 4, for example). Each spinning pack 12 is supplied with a high-temperature liquid molten polymer (yarn material) from a pipe (not shown). A spinneret 13 is disposed at the lower end of each spinning pack 12. The spinneret 13 has, for example, a plurality of nozzles (not shown). The spinning pack 12 discharges the yarn material from the plurality of nozzles of the spinneret 13 respectively (in other words, spins the yarn Y). The yarn material discharged from the plurality of nozzles is cooled by the cooling device 3 and becomes a yarn Y composed of a plurality of filaments f. That is, one yarn Y is spun from one spinneret 13. Alternatively, each spinneret 13 may have only one nozzle. In this case, the yarn Y is produced as a monofilament yarn. Note that the yarn material immediately after being discharged from the spinneret 13 (before being cooled and solidified) also corresponds to the yarn of the present invention.

[0041] The cooling device 3 is configured to cool and solidify the yarn material discharged from the plurality of spinnerets 13 with cooling air. The cooling device 3 is disposed below the spinning device 2. As shown in FIG. 1, the cooling device 3 includes a hollow box body 20 and a cooling cylinder 21. Note that in FIG. 1, only one cooling cylinder 21 is shown.

[0042] The casing 20 has a main body 20a and a cover member 20b disposed above the main body 20a. In the present embodiment, the end portion of the cover member 20b in the horizontal direction is bent downward. Note that the shape of the cover member 20b is not limited to this. The cover member 20b may be formed, for example, simply in a flat plate shape. In this case, the labor of processing the cover member 20b can be reduced. The cover member 20b is screwed to the main body 20a by, for example, screws (not shown). By removing the screws, the cover member 20b can be separated from the main body 20a. The internal space of the casing 20 is partitioned vertically by, for example, a rectifying plate 26 disposed substantially horizontally as shown in FIG. 1. The rectifying plate 26 is formed of a material having a rectifying function such as perforated metal.

[0043] The plurality of cooling cylinders 21 are configured to guide cooling air to the yarn material. The plurality of cooling cylinders 21 are fixed to the casing 20. The plurality of cooling cylinders 21 extend in the vertical direction. The plurality of cooling cylinders 21 are respectively disposed directly below the plurality of spinning nozzles 13. That is, the cooling cylinders 21 are disposed so as to surround the yarn material spun from the spinning nozzles 13 when viewed from the vertical direction. Each cooling cylinder 21 has a filter member 22 and an upper cylinder member 23.

[0044] The filter member 22 is a member for guiding the cooling air inward in the radial direction of the corresponding cooling cylinder 21. The filter member 22 has a punching filter 22a and a cooling filter 22b. The punching filter 22a is a substantially cylindrical member. The punching filter 22a is formed of a material having a rectifying function such as punching metal, similar to the rectifying plate 26. The punching filter 22a extends upward from the position of the lower end of the upper space of the box body 20 (the space above the rectifying plate 26) and protrudes above the upper end of the cover member 20b. The upper end portion of the punching filter 22a is disposed inside the upper cylinder member 23 in the radial direction of the cooling cylinder 21. The cooling filter 22b is a substantially cylindrical member. The peripheral wall portion of the cooling filter 22b is formed of, for example, a mesh-like material having a rectifying function. The cooling filter 22b is disposed inside the punching filter 22a in the radial direction. The cooling filter 22b protrudes above the upper end of the cover member 20b, similar to the punching filter 22a.

[0045] The upper cylinder member 23 is a substantially cylindrical member. The upper cylinder member 23 is fixed to, for example, the upper plate portion disposed at the uppermost side of the cover member 20b. For example, a flange is formed at the lower end portion of the upper cylinder member 23, and the flange is fixed to the lower surface of the upper plate portion of the cover member 20b. The upper cylinder member 23 is disposed so as to surround the filter member 22 and press the filter member 22 from above. The upper cylinder member 23 is configured not to allow air to permeate in the radial direction of the cooling cylinder 21. Thereby, the inflow of outside air into the inside of the cooling cylinder 21 in the radial direction of the cooling cylinder 21 is suppressed. The cooling cylinder 21 is configured to guide the cooling air upward (to the vicinity of the upper end portion of the cooling cylinder 21).

[0046] A plurality of partition cylinders 24 are disposed at positions directly below the plurality of filter members 22 in the lower space of the box body 20 (the space below the rectifying plate 26). The partition cylinder 24 is configured not to allow air to permeate in the radial direction of the partition cylinder 24. The yarn material discharged from a certain spinneret 13 and descending passes through the internal space of the filter member 22 and the internal space of the partition cylinder 24 disposed directly below the spinneret 13 in this order.

[0047] A duct 27 is connected to the rear side portion at the lower part of the box body 20. The duct 27 is connected to a compressed air source (not shown). Air for cooling the yarn material is sent into the duct 27 by the compressed air source. The cooling air is supplied into the lower space of the box body 20 through the duct 27. Hereinafter, the air flow in the box body 20 will be described (see also the arrows shown in FIG. 1). The air flowing into the lower space of the box body 20 passes through the flow rectifying plate 26 and is rectified upward, and then flows into the upper space of the box body 20. Since the wall of the partition cylinder 24 does not allow air to pass through, air does not directly flow into the partition cylinder 24 from the lower space of the box body 20. The air flowing into the upper space of the box body 20 is rectified when passing through the filter member 22 (punching filter 22a and cooling filter 22b), and then flows into the radially inner side of the filter member 22. Thereby, air is blown onto the yarn material from the entire outer circumference of the filter member 22, and the yarn material is cooled to become the yarn Y.

[0048] The cooling device 3 is configured to be movable up and down by an air cylinder 28 (the moving mechanism of the present invention). More specifically, the air cylinder 28 is erected on the floor surface of the factory, for example. The piston rod 28a extends in the vertical direction. A cover member 29 extending downward is fixed to the lower end of the box body 20. The tip of the piston rod 28a is fixed to the side surface of the cover member 29. In such a configuration, the entire cooling device 3 can move between a first position (see FIG. 1) when the spinning facility 1 is operating and a second position (see FIG. 2) below the first position by the operation of the air cylinder 28. When the cooling device 3 is located at the first position, the yarn Y can be produced. When the cooling device 3 is located at the first position, a force directed upward (toward the spinning device 2 side) is applied to the cooling device 3 and the slow cooling section 4 by the air cylinder 28. When the cooling device 3 is located at the second position, a working space Sw (details will be described later) is formed between the spinning device 2 and the cooling device 3 in the vertical direction.

[0049] The slow cooling section 4 is disposed vertically between the spinning device 2 and the cooling device 3. The slow cooling section 4 is configured to gradually cool (slowly cool) the yarn material until the yarn material discharged from the spinning device 2 is cooled by the cooling device 3. A slow cooling space Ss for slowly cooling the yarn material is formed in the slow cooling section 4. Details of the slow cooling section 4 will be described later.

[0050] The oil application section 5 is for applying an oil agent to a plurality of yarns Y. The oil application section 5 is disposed below the cooling device 3. The oil application section 5 has a plurality of oil guides (not shown) with which the plurality of yarns Y cooled by the cooling device 3 come into contact respectively. The plurality of oil guides discharge the oil agent to the plurality of yarns Y respectively to apply the oil agent to the yarns Y. The plurality of yarns Y to which the oil agent is applied by the oil application section 5 are taken up by a take-up roller (not shown). Further, the plurality of yarns Y are sent to a winding device (not shown). The plurality of yarns Y are wound around a plurality of bobbins (not shown) in the winding device respectively.

[0051] (Detailed Configuration of Slow Cooling Section) Next, the detailed configuration of the slow cooling section 4 will be described with reference to FIGS. 3 to 5. FIG. 3 is a perspective view of the slow cooling section 4 and its vicinity. FIG. 4 is a perspective view showing a state in which a block member 30 (described later) is lifted from an adjustment section 40 (described later). FIG. 5 is an enlarged view of the slow cooling section 4 and its vicinity members. The appropriate length in the vertical direction of the above-described slow cooling space Ss (more specifically, the appropriate distance in the vertical direction between the lower surface of the spinneret 13 and the upper end of the cooling cylinder 21) varies depending on the type of the yarn Y to be produced, the thickness and number of the filaments f, and the like. The slow cooling section 4 and the like are configured as follows in order to make it possible to change the length in the vertical direction of the slow cooling space Ss with a small number of members even when the number of yarns Y that can be spun in the spinning facility 1 is large.

[0052] The slow cooling section 4 includes a block member 30 and an adjustment section 40. The block member 30 is a member for forming a slow cooling space Ss. The adjustment section 40 is configured to be able to adjust the vertical positional relationship between the block member 30 and the cooling cylinder 21. Thereby, as will be described later, the adjustment section 40 is configured to be able to adjust the distance in the vertical direction between the lower surface 13a (see FIG. 5) of the spinneret 13 and the upper end of the cooling cylinder 21 (that is, the length L in the vertical direction of the slow cooling space Ss; see FIG. 5).

[0053] As shown in FIGS. 3 and 4, the block member 30 is a member having a substantially rectangular parallelepiped shape. The block member 30 is a metal member made of, for example, an aluminum alloy. The block member 30 is placed on a plurality of placement portions 41 (described later) of the adjustment portion 40. The block member 30 is disposed above the box body 20. A plurality of first through holes 31 penetrating in the vertical direction and a plurality of second through holes 32 (working holes of the present invention) also penetrating in the vertical direction are formed in the block member 30. The block member 30 is solid, for example, except for portions where the plurality of first through holes 31 and the plurality of second through holes 32 are formed. The plurality of first through holes 31 are formed at positions corresponding to the plurality of cooling cylinders 21 in the horizontal direction. In the present embodiment, the plurality of first through holes 31 are arranged in a zigzag shape along the left-right direction (see FIGS. 3 and 4). The plurality of first through holes 31 are formed such that the plurality of cooling cylinders 21 (more specifically, portions of the plurality of upper cylinder members 23 excluding the flange formed at the lower end and the vicinity thereof) can be inserted in the vertical direction respectively. In other words, the block member 30 has a plurality of surrounding surfaces 33 forming the plurality of first through holes 31. The plurality of surrounding surfaces 33 are substantially circular when viewed from the vertical direction. The plurality of surrounding surfaces 33 are configured to surround at least an upper part (at least a part in the vertical direction) of the plurality of cooling cylinders 21 respectively (see FIG. 5). A slow cooling space Ss is formed by a portion of the plurality of surrounding surfaces 33 above the plurality of cooling cylinders 21. The plurality of second through holes 32 are formed at positions corresponding to the plurality of placement portions 41 described later in the horizontal direction. The second through hole 32 has, for example, a small diameter portion 32a and a large diameter portion 32b. The small diameter portion 32a extends from the upper end of the block member 30 to the middle in the vertical direction. The large diameter portion 32b is disposed below the small diameter portion 32a and extends to the lower end of the block member 30. The large diameter portion 32b has a larger diameter than the small diameter portion 32a. Thereby, a downward contact surface 32c is formed at the boundary between the small diameter portion 32a and the large diameter portion 32b. The contact surface 32c is a surface that can contact the placement portion 41 described later. The block member 30 can be placed on the plurality of placement portions 41. Further, the block member 30 can be moved by an operator with respect to the plurality of placement portions 41.

[0054] Gaps 34 are formed between the surrounding surfaces 33 and the outer peripheral surfaces of the cooling cylinders 21 (the outer peripheral surfaces 23a of the upper cylinder members 23). The gaps 34 are formed to minimize the possibility that the surrounding surfaces 33 and the cooling cylinders 21 (the upper cylinder members 23) will come into contact with each other and become stuck during the adjustment work described below. On the other hand, it is preferable that the gaps 34 are as narrow as possible to prevent outside air from entering the slow-cooling space Ss.

[0055] As shown in Figs. 3 to 5, a plate-shaped packing 35 is placed on the upper surface of the block member 30 and is disposed substantially horizontally. The packing 35 is a sealing member for sealing a gap between the lower surface of the spinning device 2 and the upper surface of the block member 30. The packing 35 is preferably a rubber member having elasticity and heat resistance, for example. The packing 35 is preferably a heat-insulating member having heat insulation properties. The packing 35 is disposed so as to be sandwiched between the spinning device 2 and the block member 30 in the vertical direction when the cooling device 3 and the slow cooling section 4 are located at the first position. The packing 35 is configured to be separable from the block member 30, for example. The packing 35 has approximately the same size as the block member 30 when viewed from the vertical direction. Almost the entire upper surface of the packing 35 is in contact with the lower surface of the frame 10 of the spinning device 2. The packing 35 has a plurality of first through holes 36 and a plurality of second through holes 37 penetrating in the vertical direction. The multiple first through holes 36 are arranged at approximately the same positions in the horizontal direction as the multiple first through holes 31. When viewed in the up-down direction, each of the multiple first through holes 36 is equal in size to or slightly smaller than each of the multiple first through holes 31. The multiple second through holes 37 are arranged at approximately the same positions in the horizontal direction as the multiple second through holes 32.

[0056] The adjustment unit 40 includes, for example, a plurality of placement portions 41 configured to place the block member 30 thereon, a plurality of bolts 42 for moving the plurality of placement portions 41 in the vertical direction respectively, and the above-described cover member 20b. The cover member 20b supports the plurality of bolts 42. The cover member 20b corresponds to the base portion of the present invention. The plurality of placement portions 41 are supported by the box body 20 so as to be movable in the vertical direction as described below. Thereby, the relative position in the vertical direction between the block member 30 and the cooling cylinder 21 can be changed. Some of the plurality of placement portions 41 are arranged, for example, to support the four corners of the block member 30 in the horizontal direction. Also, another one of the plurality of placement portions 41 may be arranged, for example, to be sandwiched between two first through holes 31 in the left-right direction (see FIGS. 3 and 4).

[0057] Each placement portion 41 has a nut 44. The nut 44 has an internal thread (not shown) and is screwed with the bolt 42. Further, the nut 44 is fixed to the bolt 42 by, for example, welding in a state where it is screwed with the bolt 42. Thereby, the nut 44 is configured to be rotatable integrally with the bolt 42. The upper surface 44a (the placement surface of the present invention) of the nut 44 can contact the above-described contact surface 32c formed on the block member 30.

[0058] The bolt 42 of the present embodiment is, for example, a known full thread bolt without a head or a known stud bolt. The bolt 42 extends in the vertical direction. The lower portion of the bolt 42 is supported by the cover member 20b. A nut 44 is fixed to the upper portion of the bolt 42. The bolt 42 is rotatable integrally with the nut 44. A screw hole 42a (see FIG. 4) is formed at the upper end portion of the bolt 42. The screw hole 42a is, for example, a hexagonal hole.

[0059] The cover member 20b is configured such that a plurality of bolts 42 are screwed therein. More specifically, for example, an insertion hole 43a through which the bolt 42 can be inserted is formed in the upper surface portion of the cover member 20b. Below the insertion hole 43a, for example, a nut 43b is disposed. The nut 43b is fixed to the cover member 20b by, for example, welding. In the present embodiment, the nut 43b is included in the cover member 20b. The lower portion of the bolt 42 is screwed with the nut 43b. By rotating the bolt 42 (and the mounting portion 41), the bolt 42 and the mounting portion 41 can move vertically with respect to the cover member 20b (i.e., with respect to the cooling device 3).

[0060] When the cooling device 3 is moved vertically by the air cylinder 28 (see FIGS. 1 and 2), the mounting portion 41 and the bolt 42 move vertically integrally with the cover member 20b (the housing 20). Accordingly, the block members 30 mounted on the plurality of mounting portions 41 move vertically integrally with the cooling device 3 when the air cylinder 28 operates.

[0061] (Detailed Configuration of Cooling Cylinder) Next, a more detailed configuration of the plurality of cooling cylinders 21 will be described with reference to FIG. 5. Each of the plurality of cooling cylinders 21 has, as described above, a filter member 22 (punching filter 22a and cooling filter 22b) and an upper cylinder member 23. The upper end portions of the punching filter 22a and the cooling filter 22b are connected by a packing 53. Although not shown, the lower end portions of the punching filter 22a and the cooling filter 22b are also connected by a packing (not shown). The upper cylinder member 23 has an outer peripheral member 51 and a lid member 52 (the pressing member of the present invention). The outer peripheral member 51 is a substantially cylindrical portion fixed to the box body 20 by, for example, a screw (not shown). The outer peripheral member 51 is disposed outside the filter member 22 in the radial direction of the filter member 22. That is, the filter member 22 is disposed inside the outer peripheral member 51 in the radial direction. In other words, when viewed from the vertical direction, the filter member 22 is disposed so as to be surrounded by the outer peripheral member 51. The lid member 52 is a ring-shaped member. The lid member 52 is configured to be able to press the filter member 22 from above, for example, via a packing 53. That is, the lid member 52 prevents the filter member 22 from moving unintentionally in the vertical direction. The lid member 52 is fixed to the upper surface of the outer peripheral member 51 by, for example, a screw (not shown). That is, the lid member 52 is configured to be detachable from the outer peripheral member 51. In other words, the lid member 52 is configured to be able to change its state between a pressed state in which it is screwed to the upper surface of the outer peripheral member 51 and a released state in which it is removed from the outer peripheral member 51. When the state of the lid member 52 is the pressed state, the lid member 52 presses the filter member 22 from above. When the state of the lid member 52 is the released state, the state in which the lid member 52 presses the filter member 22 from above is released, and the filter member 22 can be lifted with respect to the box body 20. The packing 53 is a seal member that contacts the lower surface of the lid member 52. The packing 53 connects the punching filter 22a and the cooling filter 22b as described above.

[0062] (Working method) Next, in the spinning equipment 1 having the above-described configuration, a working method performed by an operator will be described with reference to FIGS. 6(a) to 8. FIGS. 6(a) and (b) are explanatory diagrams showing the procedure for adjusting the height of the block member 30. FIGS. 7(a) and (b) are explanatory diagrams showing the procedure for removing the filter member 22. FIG. 8 is an enlarged view of the slow cooling section 4 and the members in its vicinity after the height of the block member 30 is adjusted. The operator can perform the adjustment work of the slow cooling section 4 and the attachment / detachment work of the filter member 22 as described below.

[0063] First, the operator performs an operation to operate the air cylinder 28 in a state where the yarn Y (yarn material) is not being spun from the spinning device 2. More specifically, the operator operates the air cylinder 28 to lower the cooling device 3 and the slow cooling section 4 and move them from the first position (see FIG. 1) to the second position (see FIGS. 2 and 6(a)). Thereby, the working space Sw described above is formed. The working space Sw is a space where the operator can access the plurality of spinning nozzles 13, the plurality of cooling cylinders 21, and the adjustment section 40. That is, the operator can perform work on the plurality of spinning nozzles 13, the plurality of cooling cylinders 21, and the adjustment section 40 in the working space Sw.

[0064] After the cooling device 3 and the slow cooling section 4 move to the second position, the block member 30 is placed on the placement section 41, and the packing 35 is placed on the block member 30. Hereinafter, such a state is referred to as a placement state. In the placement state, a state where the plurality of surrounding surfaces 33 respectively surround the upper portions of the plurality of cooling cylinders 21 is maintained.

[0065] In the placed state, the operator can perform the height adjustment (adjustment operation) of the slow cooling unit 4. Specifically, as shown in FIG. 6(b), in the working space Sw, the operator inserts, for example, a hexagon wrench Hw through the second through hole 37 of the packing 35 and the second through hole 32 of the block member 30, and inserts the tip of the hexagon wrench Hw into the screw hole 42a of the bolt 42. Then, the operator rotates the hexagon wrench Hw with the vertical direction as the rotation axis direction, thereby moving the bolt 42 in the vertical direction (that is, moving the mounting portion 41 in the vertical direction). As a result, the block member 30 on the mounting portion 41 moves in the vertical direction, and the relative position in the vertical direction between the surrounding surface 33 and the cooling cylinder 21 is changed.

[0066] When moving the block member 30 in the vertical direction, if only one mounting portion 41 is moved in the vertical direction, the block member 30 can be supported only by the one mounting portion 41. In this case, the block member 30 may lose its balance and tilt slightly with respect to the horizontal direction. Then, there is a possibility that the plurality of surrounding surfaces 33 come into contact with the plurality of cooling cylinders 21 and cannot move. In order to avoid such a situation where the block member 30 cannot move, it is required to maintain the block member 30 in a substantially horizontal state. Therefore, in order to maintain the balance of the block member 30, it is preferable that two or more mounting portions 41 are moved in the vertical direction at the same time. That is, it is preferable that two or more hexagon wrenches Hw are inserted into two or more screw holes 42a and rotated simultaneously. For example, one operator may rotate two hexagon wrenches Hw at the same time. Alternatively, two or more operators may rotate two or more hexagon wrenches Hw at the same time.

[0067] Also, in the above-described mounted state, the operator can perform the attaching and detaching operations of the filter member 22. For example, the operator uses a driver (not shown) to remove a screw (not shown) that fixes the lid member 52 to the outer peripheral member 51. As a result, the state of the lid member 52 is changed from the above-described pressing state to the released state. Then, the operator lifts the lid member 52 and takes it out from the first through hole 31 of the block member 30. Thereby, the lid member 52 that presses the filter member 22 from above is removed (see Fig. 7(a)). Then, the operator can lift the filter member 22 (the punching filter 22a and the cooling filter 22b connected by the packing 53) and remove it from the cooling device 3 (see Fig. 7(b)). The filter member 22 may be, for example, reinstalled in the cooling device 3 after being cleaned. Alternatively, another new filter member 22 may be installed in the cooling device 3. In this way, the attaching and detaching operations of the filter member 22 are performed.

[0068] Also, in the working space Sw, the operator can perform, for example, the cleaning operation of the spinneret 13 in combination with the adjustment operation of the slow cooling section 4 and / or the attaching and detaching operation of the filter member 22.

[0069] After that, the operator operates the air cylinder 28 to return the cooling device 3 and the slow cooling section 4 from the second position to the first position. As a result, the length L in the vertical direction of the slow cooling space Ss is changed, for example, from the length L1 (see Fig. 5) before adjustment to the length L2 (see Fig. 8) after adjustment. Note that the block member 30 and the packing 35 are being forced upward by the air cylinder 28. Therefore, the gap between the block member 30 and the lower surface of the spinning device 2 is effectively sealed by the packing 35. Also, substantially the entire upper surface of the packing 35 is in contact with the lower surface of the frame 10 of the spinning device 2. When returning the cooling device 3 and the slow cooling section 4 from the second position to the first position, it is not necessary to perform precise alignment of the packing 35.

[0070] As described above, a single block member 30 can surround a plurality of cooling cylinders 21. Further, by adjusting the relative position in the vertical direction between the block member 30 and the plurality of cooling cylinders 21 by the adjusting unit 40, the distance in the vertical direction between the spinneret 13 and the cooling device 3 (that is, the length of the slow cooling space Ss in the vertical direction) can be changed. Therefore, even when the number of yarns Y that can be spun in the spinning facility 1 is large, the length L of the slow cooling space Ss in the vertical direction can be changed with a small number of members.

[0071] Also, the packing 35, which is a sealing member, can surely prevent outside air from entering the slow cooling space Ss through the gap between the spinning device 2 and the block member 30. For this reason, temperature fluctuations of the spinneret 13 due to outside air can be suppressed.

[0072] Also, the packing 35 is a heat insulating member. For this reason, heat transfer between the spinning device 2 and the block member 30 can be suppressed. Thereby, temperature fluctuations of the spinneret 13 can be further suppressed.

[0073] Also, by moving the cooling device 3 to the second position, work can be performed on the spinneret 13, the cooling cylinder 21, and the adjusting unit 40 in the work space Sw. Therefore, good workability can be ensured.

[0074] Also, when the cooling device 3 moves to the second position, if the block member 30 is configured to move relative to the cooling device 3, the block member 30 and the plurality of cooling cylinders 21 will be temporarily separated. For this reason, when moving the cooling device 3 from the second position to the first position, it is necessary to align the plurality of surrounding surfaces 33 and the plurality of cooling cylinders 21, which may be time-consuming. In this regard, in the present embodiment, the block member 30 moves integrally with the cooling device 3. For this reason, when moving the cooling device 3, the state where the plurality of surrounding surfaces 33 surround the plurality of cooling cylinders 21 can be maintained. Therefore, it is possible to avoid the occurrence of the need for the above alignment.

[0075] Further, in the present embodiment, the block member 30 can be easily removed from the placement portion 41 as needed.

[0076] Also, with a simple structure using bolts 42, the position of the placement portion 41 in the vertical direction can be precisely adjusted. In other words, with a simple structure, the relative position between the block member 30 and the plurality of cooling cylinders 21 can be precisely adjusted.

[0077] Further, the adjustment portion 40 has a base portion (cover member 20b) onto which a plurality of bolts 42 are screwed. Each of the plurality of placement portions 41 is configured to be movable in the vertical direction with respect to the cover member 20b integrally with the corresponding bolt 42. Therefore, the placement portion 41 can be moved in the vertical direction with a simple structure.

[0078] Also, the placement portion 41 can be formed using generally inexpensive nuts 44. Therefore, the cost of the members can be reduced.

[0079] Also, with the block member 30 placed on the placement portion 41, a tool (a hexagonal wrench Hw in the present embodiment) for turning the bolt 42 can be passed through the second through-hole 32, allowing the tool to access the bolt 42. For this reason, the bolt 42 can be rotated with the block member 30 remaining placed on the placement portion 41. That is, when rotating the bolt 42, it is not necessary to remove the block member 30 from the placement portion 41. Therefore, the labor required for manually adjusting the relative position between the block member 30 and the cooling cylinder 21 can be reduced.

[0080] Also, the block member 30 is placed on the plurality of placement portions 41. For this reason, the balance of the block member 30 can be maintained well.

[0081] Also, by changing the state of the lid member 52 from the pressed state to the released state, the filter member 22 can be lifted and removed from the cooling device 3 without moving the block member 30 relative to the cooling device 3.

[0082] In addition, the filter member 22 can be pressed from above by the lid member 52 having a simple structure, and the filter member 22 can be detachably removed from the cooling device 3.

[0083] Next, a modified example in which the above embodiment is modified will be described. However, for those having the same configuration as the above embodiment, the same reference numerals will be given and the description thereof will be omitted as appropriate.

[0084] (1) The spinning facility 1 may include a plurality of covering members 60 as shown in FIG. 9. The covering member 60 is a member that covers the lower end of the gap 34 formed between the surrounding surface 33 of the block member 30 and the cooling cylinder 21 (more specifically, the outer peripheral surface 23a of the upper cylinder member 23). The covering member 60 is configured to be movable at least in the vertical direction with respect to the extending portion 23E that extends below the lower surface of the block member 30 in the cooling cylinder 21 (upper cylinder member 23). That is, each of the plurality of covering members 60 may be, for example, a rubber ring configured to surround the extending portion 23E. Thereby, when the yarn Y is produced, the gap 34 can be covered by the covering member 60. Therefore, even when the gap 34 is large, it is possible to prevent the outside air from flowing into the slow cooling space Ss. Therefore, it is possible to achieve both ease of adjusting the position of the block member 30 and good yarn quality. Alternatively, each of the plurality of covering members 60 may be configured to be detachable from the cooling cylinder 21 (upper cylinder member 23). That is, the covering member 60 may be, for example, a ring member having a plurality of ring pieces (not shown) configured to be divisible in the circumferential direction. Thereby, it is possible to prevent the covering member 60 from getting in the way during the adjustment work. In this modified example, one covering member (not shown) configured to cover all of the plurality of gaps 34 may be provided. Alternatively, a plurality of covering members (not shown) configured to cover some of the plurality of gaps 34 may be provided.

[0085] (2) In the above-described embodiments, the lid member 52 of the cooling cylinder 21 is screwed to the outer peripheral member 51, but this is not limiting. The lid member 52 and the outer peripheral member 51 may have magnets (not shown), for example. Thereby, the lid member 52 may be detachably attached to the outer peripheral member 51 by magnetic force. Also, although the lid member 52 is ring-shaped, this is not limiting. The lid member 52 may have any shape as long as it is configured to change its state between the above-described pressed state and the released state.

[0086] (3) In the above-described embodiments, the lid member 52 is detachable from the outer peripheral member 51, but this is not limiting. The lid member 52 may be fixedly attached to the outer peripheral member 51 by welding, for example, and may not be detachable. Alternatively, the cooling cylinder 21 may be formed of a single member. In these cases, when detaching the filter member 22, it is necessary to separate the cover member 20b of the box body 20 from the main body 20a. As a preparatory work for this, it is necessary to lift the block member 30 and move it away from the plurality of placement portions 41.

[0087] (4) The positions of the plurality of placement portions 41 in the horizontal direction are not limited to those described above. Considering the workability of adjusting the height of the block member 30, it is preferable that the plurality of placement portions 41 are designed to be arranged at optimal positions.

[0088] (5) The second through hole 32 of the block member 30 does not necessarily penetrate the block member 30 in the vertical direction. The second through hole 32 may extend in an oblique direction, for example, as long as it is formed so that a tool can access the bolt 42. Alternatively, the second through hole 32 does not necessarily have to be formed. However, in this case, it is necessary to move the block member 30 away from the plurality of placement portions 41 during the adjustment work.

[0089] (6) In the above-described embodiments, the adjustment unit 40 has been described as having a plurality of placement parts 41, but this is not limitative. The adjustment unit 40 may have one large placement part (not shown). Such a placement part may be supported by one or a plurality of bolts 42.

[0090] (7) In the above-described embodiments, the placement part 41 has been described as having a nut 44, but this is not limitative. The placement part 41 may be constituted by a member other than the nut 44. For example, in the above-described embodiments, the bolt 42 has been described as not having a head, but this is not limitative. The bolt 42 may have a head in which, for example, a hexagonal hole is formed. The placement part of the present invention may be constituted by such a head. Note that the bolt 42 may have a screw hole (not shown) having a shape other than a hexagonal hole. Further, when the bolt 42 has a head, a screw hole is not necessarily formed in the head. That is, for example, a known hexagonal bolt having a head in a substantially hexagonal prism shape may correspond to both the placement part and the bolt of the present invention. However, in this case, it is necessary to move the block member 30 away from the plurality of placement parts 41 during the adjustment operation.

[0091] (8) The configuration of the base part (cover member 20b) is not limited to that described above. In the example described above, the nut 43b has been described as being fixed to the cover member 20b, but this is not limitative. For example, a female screw may be formed in the insertion hole 43a formed in the cover member 20b. Thereby, the bolt 42 may be screwed into the insertion hole 43a. Alternatively, the base part may be formed by a member (not shown) different from the cover member 20b.

[0092] (9) In the above-described embodiments, the adjusting unit 40 is assumed to have a bolt 42 extending in the vertical direction, and the mounting unit 41 is assumed to move vertically integrally with the bolt 42. However, this is not limitative. The adjusting unit (not shown) may have, for example, a rack and pinion mechanism including a rack (not shown) and a pinion gear (not shown). More specifically, a mounting unit (not shown) may be provided on a rack extending in the vertical direction. In this case, the pinion gear may be substantially orthogonal to the vertical direction. When the pinion gear is rotated, the rack (mounting unit) may be moved in the vertical direction. Alternatively, the adjusting unit (not shown) may have, for example, a jack (such as a pantograph jack, not shown). For example, two pantograph jacks (not shown) may be provided between the block member 30 and the box body 20 (cover member 20b) in the vertical direction. The two pantograph jacks may be respectively arranged so as to support both end portions of the block member 30 in the longitudinal direction (left-right direction).

[0093] (10) In the above-described embodiments, the adjusting unit 40 has the mounting unit 41, and the block member 30 is assumed to be placed on the mounting unit 41. That is, the block member 30 can be easily separated from the adjusting unit 40 and the cooling device 3. However, this is not limitative. For example, the block member 30 and the adjusting unit 40 may be configured such that separation is difficult or impossible.

[0094] (11) In the above-described embodiments, when the air cylinder 28 operates, the block member 30 is configured to move integrally with the cooling device 3. However, this is not limitative. The block member 30 may be fixed to the spinning device 2, for example. That is, when the air cylinder 28 moves the cooling device 3 from the first position to the second position, the slow cooling unit 4 may be configured such that the adjusting unit 40 and the block member 30 are separated from each other. Also, a packing 35 does not necessarily have to be provided between the spinning device 2 and the block member 30.

[0095] (12) In the above-described embodiments, it is assumed that when the air cylinder 28 moves the cooling device 3 from the first position to the second position, a working space Sw is formed. That is, it is assumed that work can be performed on the plurality of spinnerets 13, the plurality of cooling cylinders 21, and the adjustment unit 40 in the working space Sw. However, this is not limitative. For example, only work on the plurality of cooling cylinders 21 and the adjustment unit 40 may be possible in the working space Sw.

[0096] (13) In the above-described embodiments, it is assumed that the air cylinder 28 is provided as a moving mechanism for moving the cooling device 3 in the vertical direction. However, this is not limitative. Instead of the air cylinder 28, for example, a hydraulic cylinder (not shown) or a ball screw mechanism (not shown) may be provided.

[0097] (14) In the above-described embodiments, it is assumed that the adjustment unit 40 is manually operated by an operator. However, this is not limitative. The adjustment unit 40 may have, for example, an electric linear actuator (not shown). In this case, the moving mechanism for moving the cooling device 3 in the vertical direction does not necessarily have to be provided. Even in such a case, the length of the slow cooling space Ss in the vertical direction can be changed by the linear actuator. Further, a control device (not shown) for controlling the linear actuator may be provided.

[0098] (15) In the above-described embodiments, it is assumed that the material of the block member 30 is an aluminum alloy, but this is not limitative. The block member 30 may be formed of a metal material other than the aluminum alloy. Alternatively, the block member 30 may be formed of a non-metallic material. Also, the block member 30 does not necessarily have to be solid. The block member 30 may be hollow.

[0099] (16) To improve the workability during the attachment and detachment operations of the filter member 22, the cooling device 3 may be configured as follows. For example, one or more openings (not shown) may be provided on the front surface of the main body 20a of the box body 20, and one or more covers (not shown) for closing each of the one or more openings may be attached. Each cover preferably extends in the left - right direction (the direction in which a plurality of cooling cylinders 21 are arranged). Each cover is preferably openable or removable from the box body 20. In such a configuration, by moving each cover with respect to the opening closed by the cover, an operator can put a hand into the internal space of the box body 20 from the front side. Thereby, for example, when the filter member 22 is attached to the box body 20, the operator can easily access the side surface of the filter member 22. Therefore, the position of the filter member 22 can be easily finely adjusted.
