Description

Spinning equipment

Technical Field

The invention relates to a spinning device.

Background

Patent document 1 discloses a spinning device for producing a yarn made of synthetic fibers. The spinning equipment includes a spinning device that ejects (spins) a high-temperature molten polymer as a thread material from a spinning nozzle, and a cooling device disposed below the spinning device. Although not shown in patent document 1, the spinning apparatus includes a plurality of spinning nozzles. The yarn material discharged from each of the plurality of spinning nozzles is cooled and solidified by the cooling device, and becomes a yarn composed of 1 or more filaments. That is, the same number of filaments as the number of spinning nozzles are produced. Further, a space (slow cooling space) for slowly cooling the yarn material discharged from the spinneret and descending is formed between the spinning device and the cooling device in the vertical direction. The appropriate length of the slow cooling space in the vertical direction (i.e., the appropriate distance between the spinneret and the cooling device in the vertical direction) differs depending on the type of the yarn material (hereinafter, referred to as the yarn type) and the thickness and number of the filaments. That is, when the type of yarn or the like is changed, the length of the slow cooling space in the vertical direction needs to be changed (referred to as the spinneret surface depth in patent document 1).

In contrast, patent document 1 discloses a device for changing the depth of a spinneret surface, which is configured to be capable of changing the depth of the spinneret surface. Specifically, the spinneret surface depth varying device includes a cylindrical upper cover fixed to the lower surface of the spinning device, and a cylindrical lower cover fixed to the upper surface of the cooling device. The upper cover is configured to surround at least an upper portion of the lower cover. The cooling device is configured to be movable in the vertical direction. The cooling device and the lower cover move in the vertical direction, thereby preventing external air from flowing into the slow cooling space and changing the surface depth of the spinneret.

Patent document 1: japanese patent laid-open publication No. 2016-108698

In recent years, the number of threads that can be spun at one time by a spinning device tends to increase gradually. In such a situation, when the upper cover and the lower cover are provided corresponding to the respective yarns, the number of parts required increases, which causes a problem of an increase in the cost of the spinning equipment.

Disclosure of Invention

The invention aims to change the length of a slow cooling space in the vertical direction by using a small number of parts even when the number of yarns to be spun is large.

The spinning apparatus of claim 1 comprises: a spinning device having a plurality of spinning nozzles for spinning threads, respectively; a cooling device disposed below the spinning device and configured to cool the plurality of filaments spun from the plurality of spinning nozzles, respectively; and a slow cooling unit disposed between the spinning device and the cooling device in a vertical direction, wherein the cooling device includes a plurality of cooling cylinders extending in the vertical direction, disposed so as to surround the plurality of yarns, respectively, and configured to guide cooling air to the plurality of yarns, and the slow cooling unit includes: a block member having a plurality of surrounding surfaces configured to surround at least a part of the plurality of cooling tubes in a vertical direction, respectively, and forming a plurality of slow cooling spaces for slow cooling the plurality of wires, respectively, by portions of the plurality of surrounding surfaces above the plurality of cooling tubes; and an adjusting section configured to be capable of adjusting a relative position in a vertical direction between the block member and the plurality of cooling cylinders.

In the present invention, a plurality of cooling cylinders can be surrounded by one block member. Further, the relative positions of the block member and the plurality of cooling tubes in the vertical direction are adjusted by the adjusting section, whereby the vertical distance between the spinneret and the cooling device (i.e., the vertical length of the slow cooling space) can be changed. Therefore, even when the number of threads that can be spun in the spinning device is large, the length of the slow cooling space in the vertical direction can be changed by a small number of members.

The spinning device according to claim 2 is the spinning device according to claim 1, wherein the spinning device includes a seal member disposed between the spinning device and the block member in a vertical direction.

If the temperature of the spinneret is varied, the yarn quality may be deteriorated. In the present invention, the seal member can reliably prevent the entry of the outside air into the slow cooling space from the gap between the spinning device and the block member. Therefore, the temperature fluctuation of the spinneret due to the outside air can be suppressed.

The spinning device of claim 3 is characterized in that, in the above-described invention 2, the sealing member is a heat insulating member.

In the present invention, heat can be suppressed from moving between the spinning device and the block member. This can further suppress temperature fluctuations in the spinneret.

The spinning device according to claim 4 is the spinning device according to any one of claims 1 to 3, wherein the spinning device includes a moving mechanism configured to move the cooling device between a 1 st position when the plurality of yarns are spun from the spinning device and a 2 nd position below the 1 st position, and when the cooling device is located at the 2 nd position, a working space in which the plurality of spinning nozzles, the plurality of cooling tubes, and the adjustment unit can be operated is formed between the spinning device and the cooling device in a vertical direction.

In the present invention, the spinneret, the cooling cylinder, and the adjusting section can be operated in the working space by moving the cooling device to the 2 nd position. Therefore, good workability can be ensured.

In the spinning machine according to claim 5, in the above-described invention 4, the block member is configured to move integrally with the cooling device when the moving mechanism is operated.

When the cooling device is moved toward the 2 nd position, the block member is temporarily separated from the plurality of cooling drums in a case where the block member is moved relative to the cooling device. Therefore, when the cooling device is moved from the 2 nd position to the 1 st position, it is necessary to align the plurality of surrounding surfaces with the plurality of cooling cylinders, which may take a lot of time. In the present invention, when the cooling device is moved, the plurality of surrounding surfaces can be maintained in a state of surrounding the plurality of cooling cylinders. Therefore, the need for the above-described alignment can be avoided.

The spinning device according to claim 6 is characterized in that, in the 5 th aspect, the adjusting portion includes 1 or more placing portions, and the 1 or more placing portions are configured to place the block member and to be movable in a vertical direction with respect to the cooling device.

In the present invention, the block member can be easily removed from the placement portion as needed.

The spinning device according to claim 7 is characterized in that, in the above-described 6 th aspect, the adjusting portion includes 1 or more bolts extending in the vertical direction and supporting the 1 or more mounting portions, respectively, and the adjusting portion is configured to move the mounting portions in the vertical direction by rotating the 1 or more bolts.

In the present invention, the position of the placement portion in the vertical direction can be precisely adjusted by a simple structure using a bolt. In other words, with a simple configuration, the relative positions of the block member and the plurality of cooling cylinders can be precisely adjusted.

The spinning device according to claim 8 is characterized in that, in the 7 th aspect, the spinning device includes a base portion to which the 1 or more bolts are screwed, the 1 or more bolts are configured to be movable in the vertical direction with respect to the base portion by rotation, and the 1 or more mounting portions are configured to be movable in the vertical direction integrally with the 1 or more bolts.

In the present invention, the placement unit can be moved in the vertical direction by a simple structure.

The spinning device according to claim 9 is characterized in that, in the 8 th aspect, the 1 or more mounting portions have 1 or more nuts each having a mounting surface in contact with the block member, and the 1 or more nuts are fixed to the 1 or more bolts, respectively.

In the present invention, the mounting portion can be formed by using an inexpensive nut. Thus, the cost of the parts can be reduced.

A spinning machine according to claim 10 is characterized in that, in any one of the inventions 7 to 9, the block member has 1 or more operation holes, and the 1 or more operation holes are used for operating the 1 or more bolts in a state where the block member is placed on the 1 or more placement portions.

In the present invention, when a tool for turning the bolt is passed through the working hole in a state where the block member is placed on the placement portion, the tool can be brought close to the bolt. Therefore, the bolt can be rotated in a state where the block member is placed on the placement portion. That is, when the bolt is rotated, it is not necessary to remove the block member from the placement portion. Therefore, the man-hours required for manually adjusting the relative position between the block member and the cooling cylinder can be reduced.

The spinning device according to claim 11 is characterized in that, in any one of the inventions 6 to 10, the adjusting unit includes a plurality of placement units as the 1 or more placement units.

In the configuration in which only one mounting portion is provided, the block member may be out of balance and inclined with respect to the horizontal direction depending on the size relationship between the mounting portion and the block member. In such a case, for example, the block member abuts against the cooling cylinder, and there is a possibility that the work for adjusting the relative position of the block member and the cooling cylinder is hindered. In this regard, in the present invention, the block member is placed on the plurality of placement portions. Therefore, the balance of the block members can be maintained well.

A spinning machine according to claim 12 is the spinning machine according to any one of the inventions 5 to 11, wherein each of the plurality of cooling cylinders includes: a filter member that is attachable to and detachable from the cooling device; and a pressing member configured to press the filter member from above, wherein the pressing member is configured to be capable of changing a state between a pressed state in which the filter member is pressed from above and a released state in which the pressed state is released and the filter member is lifted when the cooling device is located at the 2 nd position.

In the configuration in which the block member is movable integrally with the cooling device, it is necessary to move the block member relative to the cooling device when the filter member is detached from the cooling device, depending on the positional relationship between the pressing member and the block member. In the present invention, by changing the state of the pressing member from the pressed state to the released state, the filter member can be lifted and removed from the cooling device without moving the block member relative to the cooling device.

The spinning device according to claim 13 is characterized in that, in the above-described 12 th invention, the pressing member is a ring member that is attachable to and detachable from an upper surface of each of the plurality of cooling cylinders.

In the present invention, the filter member can be pressed from above by the pressing member of a simple structure, and the filter member can be detached from the cooling device.

A spinning device according to claim 14 is the spinning device according to any one of claims 1 to 13, wherein the plurality of cooling cylinders each have a plurality of extending portions extending downward from a lower surface of the block member, and the spinning device includes 1 or more covering members, and the 1 or more covering members are configured to be movable at least in a vertical direction with respect to the plurality of extending portions so as to cover a plurality of gaps formed between the plurality of cooling cylinders and the plurality of surrounding surfaces.

If the clearance between the surrounding surface of the block member and the outer peripheral surface of the cooling cylinder is large, the outside air easily flows into the slow cooling space, and the quality of the yarn may be adversely affected. Therefore, the gap is preferably as small as possible. However, if the gap is too small, the block member, the surrounding surface, and the outer peripheral surface of the cooling cylinder easily come into contact with each other when the relative position of the block member and the cooling cylinder in the vertical direction is adjusted. Therefore, the block member and the cooling cylinder cannot move relative to each other, and the adjustment operation may be difficult. In the present invention, the covering member can cover the gap between the surrounding surface of the block member and the outer peripheral surface of the cooling cylinder when the wire is produced. Therefore, even when the gap is large, the inflow of the outside air into the slow cooling space can be prevented. Therefore, the ease of position adjustment of the block member and the good quality of the yarn can be both achieved.

The spinning device according to claim 15 is characterized in that, in the 14 th aspect, the 1 or more covering members are configured to be detachable from the plurality of extending portions.

In the present invention, the covering member can be prevented from being an obstacle when the relative position of the surrounding surface of the block member and the cooling cylinder is adjusted.

Detailed Description

Next, embodiments of the present invention will be explained. For convenience of explanation, the directions shown in fig. 1 are the up-down direction and the front-rear direction. The vertical direction (vertical direction on the paper surface of fig. 1) is a vertical direction in which gravity acts. The front-rear direction (left-right direction on the paper surface of fig. 1) is a direction orthogonal to the up-down direction. A direction (a direction perpendicular to the paper surface of fig. 1) perpendicular to both the vertical direction and the front-rear direction is defined as a left-right direction.

(spinning apparatus)

An outline of the spinning device 1 of the present embodiment will be described with reference to the schematic diagram of fig. 1. The spinning apparatus 1 is an apparatus for producing a yarn Y composed of synthetic fibers. The spinning facility 1 includes a spinning device 2, a cooling device 3, a slow cooling unit 4, and a finish application unit 5.

The spinning device 2 is a melt spinning device configured to spin a plurality of yarns Y made of a molten polymer. The spinning device 2 includes a frame 10 having a substantially rectangular parallelepiped shape, a plurality of module cases 11 formed in the frame 10, and a plurality of spinning modules 12 attached to the plurality of module cases 11, respectively. The plurality of spinning modules 12 are arranged in a zigzag shape, for example, along the left-right direction (not shown, and the horizontal arrangement is, for example, see the cooling cylinder 21 and the 1 st through hole 31 described later in fig. 4). A molten polymer (yarn material) in a high-temperature liquid state is supplied to each spinning module 12 from a pipe (not shown). A spinning nozzle 13 is disposed at the lower end of each spinning pack 12. The spinning spinneret 13 has, for example, a plurality of nozzles (not shown). The spin pack 12 discharges the yarn material (in other words, the spun yarn Y) from each of the plurality of nozzles of the spin pack 13. The yarn material discharged from the plurality of nozzles is cooled by the cooling device 3 to be a yarn Y composed of a plurality of filaments f. That is, one yarn Y is spun from one spinning nozzle 13. Alternatively, each spinneret 13 may have only one nozzle. In this case, the yarn Y is produced as a monofilament. 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.

The cooling device 3 is configured to cool and solidify the yarn material discharged from the plurality of spinning nozzles 13 by 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 casing 20 and a cooling cylinder 21. In fig. 1, only one cooling drum 21 is shown.

The case 20 includes a main body 20a and a cover member 20b disposed above the main body 20 a. In the present embodiment, the end portion of the cover member 20b in the horizontal direction is bent downward. The shape of the cover member 20b is not limited to this. The cover member 20b may be simply formed in a flat plate shape, for example. In this case, the number of steps for processing the cover member 20b can be reduced. The cover member 20b is screwed to the main body 20a by a screw not shown. The cover member 20b can be detached from the main body 20a by removing the screw. For example, as shown in fig. 1, the inner space of the case 20 is vertically partitioned by a flow regulating plate 26 disposed substantially horizontally. The rectifying plate 26 is formed of a material having a rectifying function such as a stamped metal.

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

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 includes a press filter 22a and a cooling filter 22 b. The press filter 22a is a substantially cylindrical member. The pressed filter 22a is formed of a material having a flow rectification function, such as a pressed metal, similarly to the flow rectification plate 26. The press filter 22a extends upward from a lower end portion of an upper space (a space above the rectifying plate 26) of the case 20 and protrudes upward from an upper end of the cover member 20 b. The upper end of the press filter 22a is disposed inside the upper tube member 23 in the radial direction of the cooling tube 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 flow regulating function. The cooling filter 22b is disposed radially inward of the press filter 22 a. The cooling filter 22b protrudes upward from the upper end of the cover member 20b, as with the press filter 22 a.

The upper cylinder member 23 is a substantially cylindrical member. The upper tube member 23 is fixed to, for example, the uppermost upper plate portion of the cover member 20 b. For example, a flange is formed at the lower end of the upper cylindrical member 23, and the flange is fixed to the lower surface of the upper plate portion of the cover member 20 b. The upper tube 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 transmit air in the radial direction of the cooling cylinder 21. This can suppress inflow of outside air into the cooling cylinder 21 in the radial direction of the cooling cylinder 21. The cooling cylinder 21 is configured to guide cooling air upward (to the vicinity of the upper end of the cooling cylinder 21).

A plurality of partition cylinders 24 are disposed in a lower space (a space below the rectifying plate 26) of the case 20 at positions directly below the plurality of filter members 22. The partition cylinder 24 is configured not to allow air to pass through in the radial direction of the partition cylinder 24. The thread 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 tube 24 arranged immediately below the spinneret 13 in this order.

A duct 27 is connected to a rear portion of a lower portion of the case 20. The pipe 27 is connected to a compressed air source (not shown). Air for cooling the thread material is fed into the duct 27 by means of a compressed air source. The cooling air is supplied into the lower space of the casing 20 through the duct 27. The flow of air in the case 20 will be described below (see the arrows shown in fig. 1). The air flowing into the lower space of the case 20 is upwardly rectified by the rectifying plate 26 and flows toward the upper space of the case 20. Further, since the wall of the partition cylinder 24 does not allow air to pass therethrough, air does not directly flow into the partition cylinder 24 from the lower space of the case 20. The air flowing into the upper space of the case 20 is rectified when passing through the filter member 22 (the ram filter 22a and the cooling filter 22b), and flows radially inward of the filter member 22. Thus, air is blown to the yarn material from the outer side of the filter member 22 over the entire circumference thereof, and the yarn material is cooled to become the yarn Y.

The cooling device 3 is configured to be movable up and down by an air cylinder 28 (moving mechanism of the present invention). More specifically, the cylinder 28 is installed upright on the floor of a workshop, for example. The piston rod 28a extends in the up-down direction. A cover member 29 extending downward is fixed to the lower end of the casing 20. The distal end of the piston rod 28a is fixed to a side surface of the cover member 29. In such a configuration, the entire cooling device 3 can move between the 1 st position (see fig. 1) and the 2 nd position (see fig. 2) below the 1 st position when the spinning device 1 is operated by the operation of the air cylinder 28. When the cooling device 3 is in position 1, a yarn Y can be produced. When the cooling device 3 is located at the 1 st position, the cooling device 3 and the gradually cooling section 4 are urged upward (toward the spinning device 2) by the air cylinder 28. When the cooling device 3 is located at the 2 nd position, a working space Sw (described later in detail) is formed in the vertical direction between the spinning device 2 and the cooling device 3.

The slow cooling section 4 is disposed between the spinning device 2 and the cooling device 3 in the vertical direction. The slow cooling section 4 is configured to gradually cool (slow cool) the yarn material discharged from the spinning device 2 until the yarn material is cooled by the cooling device 3. The slow cooling section 4 is formed with a slow cooling space Ss for slowly cooling the wire material. The details of the slow cooling portion 4 will be described later.

The finish application unit 5 applies a finish to the plurality of threads Y. The oil application unit 5 is disposed below the cooling device 3. The finish oil applying unit 5 includes a plurality of finish oil guides (not shown) that are in contact with the plurality of yarns Y cooled by the cooling device 3, respectively. The plurality of oil guides respectively spray oil to the plurality of yarns Y and apply the oil to the yarns Y. The plurality of yarns Y to which the finish is applied by the finish applying unit 5 are pulled by a pulling roller (not shown). Further, the plurality of yarns Y are fed to a winding device (not shown). The plurality of yarns Y are wound around a plurality of bobbins (not shown) by a winding device.

(detailed construction of Slow Cooling portion)

Next, the detailed structure of the slow cooling unit 4 will be described with reference to fig. 3 to 5. Fig. 3 is a perspective view of the slow cooling portion 4 and its vicinity. Fig. 4 is a perspective view showing a state in which the block member 30 (described later) is lifted from the adjustment portion 40 (described later). Fig. 5 is an enlarged view of the slow cooling section 4 and its vicinity. The appropriate length in the vertical direction of the 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) differs 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 is configured as follows so that the length of the slow cooling space Ss in the vertical direction can be changed by a small number of parts even when the number of yarns Y that can be spun in the spinning device 1 is large.

The slow cooling portion 4 includes a block member 30 and an adjustment portion 40. The block section 30 is a section for forming the slow cooling space Ss. The adjustment unit 40 is configured to be able to adjust the positional relationship between the block member 30 and the cooling cylinder 21 in the vertical direction. Thus, as will be described later, the adjusting 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 barrel 21 (i.e., the length l of the slow cooling space Ss in the vertical direction, see fig. 5).

As shown in fig. 3 and 4, the block member 30 is a substantially rectangular parallelepiped member. The block member 30 is, for example, a metal member made of 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 on the upper side of the case 20. The block member 30 is formed with a plurality of 1 st through holes 31 penetrating in the vertical direction and a plurality of 2 nd through holes 32 (working holes of the present invention) also penetrating in the vertical direction. The block member 30 is solid except for a portion where a plurality of 1 st through holes 31 and a plurality of 2 nd through holes 32 are formed, for example. The 1 st through holes 31 are formed at positions corresponding to the cooling cylinders 21 in the horizontal direction. In the present embodiment, the plurality of 1 st through holes 31 are arranged in a zigzag shape along the left-right direction (see fig. 3 and 4). The plurality of 1 st through holes 31 are formed so that the plurality of cooling cylinders 21 (more specifically, portions of the plurality of upper cylinder members 23 other than the flange formed at the lower end portion and the vicinity thereof) can be inserted in the vertical direction. In other words, the block member 30 has a plurality of surrounding surfaces 33 forming a plurality of 1 st through holes 31. The plurality of surrounding surfaces 33 have a substantially circular shape when viewed in the vertical direction. The plurality of surrounding surfaces 33 are configured to surround at least upper portions (at least a portion in the vertical direction) of the plurality of cooling cylinders 21, respectively (see fig. 5). The cooling buffer space Ss is formed by the upper portion of the plurality of surrounding surfaces 33 with respect to the plurality of cooling drums 21. The plurality of 2 nd through holes 32 are formed at positions corresponding to a plurality of placement portions 41 to be described later in the horizontal direction. The 2 nd through hole 32 has, for example, a small diameter portion 32a and a large diameter portion 32 b. The small diameter portion 32a extends from the upper end of the block member 30 to halfway 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 diameter of the large diameter portion 32b is larger than that of the small diameter portion 32 a. Thereby, a downward contact surface 32c is formed at the boundary between the small diameter portion 32a and the large diameter portion 32 b. The contact surface 32c is a surface that can be brought into contact with a mounting 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 relative to the plurality of placement portions 41 by an operator.

Gaps 34 are formed between the plurality of surrounding surfaces 33 and the outer peripheral surfaces of the plurality of cooling cylinders 21 (the outer peripheral surface 23a of the upper cylinder member 23). The gap 34 is formed to prevent the surrounding surface 33 and the cooling cylinder 21 (upper cylinder member 23) from coming into contact with each other and becoming stationary as much as possible during adjustment work described later. On the other hand, the gap 34 is preferably as narrow as possible in order to suppress the intrusion of the outside air into the slow cooling space Ss.

As shown in fig. 3 to 5, a plate-like spacer 35 arranged substantially horizontally is placed on the upper surface of the block member 30. The gasket 35 is a sealing member for closing a gap between the lower surface of the spinning device 2 and the upper surface of the block member 30. The gasket 35 is preferably a rubber member having elasticity and heat resistance, for example. The spacer 35 is preferably a heat insulating member having heat insulation properties. The spacer 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 portion 4 are located at the 1 st position. The spacer 35 is configured to be separable from the block member 30, for example. The spacer 35 has substantially the same size as the block member 30 when viewed in the vertical direction. Substantially the entire upper surface of the spacer 35 is in contact with the lower surface of the frame 10 of the spinning device 2. The spacer 35 is formed with a plurality of 1 st through holes 36 and a plurality of 2 nd through holes 37 penetrating in the vertical direction. The plurality of 1 st through holes 36 are arranged at substantially the same positions as the plurality of 1 st through holes 31 in the horizontal direction. Each of the plurality of 1 st through holes 36 has the same size as or slightly smaller than each of the plurality of 1 st through holes 31 when viewed in the vertical direction. The plurality of 2 nd through holes 37 are arranged at substantially the same positions as the plurality of 2 nd through holes 32 in the horizontal direction.

The adjustment unit 40 includes, for example, a plurality of placement units 41 configured to place the block member 30 thereon, a plurality of bolts 42 for moving the placement units 41 in the vertical direction, and the cover member 20b described above. The cover member 20b supports a plurality of bolts 42. The cover member 20b corresponds to a base portion of the present invention. As described below, the plurality of placement portions 41 are supported by the case 20 so as to be movable in the vertical direction. This allows the relative position of the block member 30 and the cooling cylinder 21 in the vertical direction to be changed. Some of the plurality of placement portions 41 are disposed at, for example, four corners in the horizontal direction of the support block member 30. Further, the other mounting portions 41 of the plurality of mounting portions 41 may be disposed so as to be sandwiched between the two 1 st through holes 31 in the left-right direction, for example (see fig. 3 and 4).

Each mounting portion 41 has a nut 44. The nut 44 has an unillustrated internal thread and is screwed to the bolt 42. Further, the nut 44 is fixed to the bolt 42 by, for example, welding in a state of being screwed with the bolt 42. Thereby, the nut 44 is configured to be rotatable integrally with the bolt 42. The upper surface 44a (mounting surface of the present invention) of the nut 44 can contact the contact surface 32c formed on the block member 30.

The bolt 42 of the present embodiment is, for example, a known full bolt having no head or a known stud bolt. The bolt 42 extends in the up-down direction. The lower portion of the bolt 42 is supported by the cover member 20 b. A nut 44 is fixed to an 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 in an upper end portion of the bolt 42. The threaded hole 42a is, for example, a hexagonal hole.

The cover member 20b is configured to be screwed with a plurality of bolts 42. More specifically, for example, insertion holes 43a through which the bolts 42 can be inserted are formed in the upper surface portion of the cover member 20 b. A nut 43b is disposed immediately below the insertion hole 43a, for example. The nut 43b is fixed to the cover member 20b by welding, for example. In the present embodiment, the nut 43b is included in the cover member 20 b. The lower portion of the bolt 42 is screwed with the nut 43 b. By rotating the bolt 42 (and the placement portion 41), the bolt 42 and the placement portion 41 can move in the vertical direction with respect to the cover member 20b (i.e., with respect to the cooling device 30).

When the cooling device 3 is moved in the vertical direction by the air cylinder 28 (see fig. 1 and 2), the mounting portion 41 and the bolt 42 move in the vertical direction integrally with the cover member 20b (the housing 20). Therefore, the block members 30 placed on the plurality of placement portions 41 move in the vertical direction integrally with the cooling device 3 when the air cylinder 28 is operated.

(detailed construction of Cooling Cartridge)

Next, a more detailed structure of the plurality of cooling drums 21 will be described with reference to fig. 5. As described above, each of the plurality of cooling drums 21 includes the filter member 22 (the pressing filter 22a and the cooling filter 22b) and the upper drum member 23. The upper end of the press filter 22a and the upper end of the cooling filter 22b are connected by a gasket 53. Although not shown, the lower end of the press filter 22a and the lower end of the cooling filter 22b are also connected by a gasket (not shown). The upper cylinder member 23 includes an outer peripheral member 51 and a cap member 52 (a pressing member of the present invention). The outer peripheral member 51 is a substantially cylindrical portion fixed to the case 20 by, for example, unillustrated screws. The outer peripheral member 51 is disposed outside the filter element 22 in the radial direction of the filter element 22. That is, the filter member 22 is disposed radially inward of the outer peripheral member 51. In other words, the filter member 22 is disposed so as to be surrounded by the outer peripheral member 51 when viewed from the up-down direction. The cover member 52 is an annular member. The cover member 52 is configured to be able to press the filter member 22 from above via a gasket 53, for example. That is, the filter member 22 is prevented from being accidentally moved in the up-down direction by the cover member 52. The cover member 52 is fixed to the upper surface of the outer peripheral member 51 by, for example, screws not shown. That is, the cover member 52 is configured to be attachable to and detachable from the outer peripheral member 51. In other words, the cover member 52 is configured to be changeable 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 detached from the outer peripheral member 51. When the state of the lid member 52 is in the pressed state, the lid member 52 presses the filter member 22 from the upper side. When the state of the lid member 52 is in 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 up with respect to the case 20. The gasket 53 is a sealing member that contacts the lower surface of the cover member 52. As described above, the spacer 53 connects the press filter 22a and the cooling filter 22 b.

(working method)

Next, in the spinning machine 1 having the above-described configuration, an operation method performed by an operator will be described with reference to fig. 6 (a) to 8. Fig. 6 (a) and (b) are explanatory views showing a procedure of height adjustment of the block member 30. Fig. 7 (a) and (b) are explanatory views showing a procedure of detaching the filter member 22. Fig. 8 is an enlarged view of the gradually cooling part 4 after the height adjustment of the block member 30 and its vicinity. The worker can perform the adjustment operation of the gradually cooling part 4 and the attachment/detachment operation of the filter member 22 as described below.

First, the operator performs an operation for operating the air cylinder 28 without spinning the yarn Y (yarn material) from the spinning device 2. More specifically, the operator moves the cooling device 3 and the gradually cooling unit 4 downward by operating the cylinder 28, and moves them from the 1 st position (see fig. 1) to the 2 nd position (see fig. 2 and 6 (a)). Thereby, the work space Sw is formed. The working space Sw is a space where the operator can access the plurality of spinning nozzles 13, the plurality of cooling tubes 21, and the adjusting section 40. That is, the operator can operate the plurality of spinning nozzles 13, the plurality of cooling tubes 21, and the adjusting section 40 in the operation space Sw.

After the cooling device 3 and the slow cooling unit 4 are moved to the 2 nd position, the block member 30 is placed on the placement unit 41, and the spacer 35 is placed on the block member 30. Hereinafter, such a state is referred to as a mounting state. In the mounted state, the surrounding surfaces 33 are maintained in a state of surrounding the upper portions of the cooling cylinders 21.

In the mounted state, the operator can perform height adjustment (adjustment work) of the slow cooling portion 4. Specifically, as shown in fig. 6 (b), in the working space Sw, the operator inserts, for example, the hexagonal wrench Hw into the 2 nd through hole 37 of the spacer 35 and the 2 nd through hole 32 of the block member 30, and inserts the tip end portion of the hexagonal wrench Hw into the screw hole 42a of the bolt 42. Then, the operator rotates the allen wrench Hw with the vertical direction as the rotation axis direction, thereby moving the bolt 42 in the vertical direction (that is, moving the placing portion 41 in the vertical direction). Thereby, the block member 30 on the placement portion 41 moves in the vertical direction, and the relative position between the surrounding surface 33 and the cooling cylinder 21 in the vertical direction is changed.

In addition, when only one placement portion 41 is moved in the vertical direction when the block member 30 is moved in the vertical direction, there is a possibility that the block member 30 may be supported only by the one placement portion 41. In this case, the block member 30 may lose balance and be slightly inclined with respect to the horizontal direction. Therefore, the plurality of surrounding surfaces 33 may come into contact with the plurality of cooling cylinders 21 without movement. In order to avoid the block 30 from being stationary, it is necessary to maintain the block 30 in a substantially horizontal state. Therefore, in order to maintain the balance of the block member 30, it is preferable to move the two or more placement portions 41 in the vertical direction at the same time. That is, it is preferable that two or more allen wrenches Hw be inserted into two or more screw holes 42a, respectively, and rotated simultaneously. For example, 1 operator may rotate two allen wrenches Hw simultaneously. Alternatively, two or more hexagonal wrenches Hw may be rotated simultaneously by 2 or more operators.

Further, the worker can attach and detach the filter member 22 in the above-described mounted state. The worker removes a screw, not shown, that fixes the cover member 52 to the outer peripheral member 51, for example, using a screwdriver, not shown. Thereby, the state of the lid member 52 is changed from the above-described pressed state to the released state. After that, the operator lifts the lid member 52 and takes out the lid member from the 1 st through hole 31 of the block member 30. Thereby, the lid member 52 pressing the filter member 22 from above is removed (see fig. 7 (a)). Thereafter, the operator can lift up the filter member 22 (the press filter 22a and the cooling filter 22b connected by the spacer 53) and detach the filter member from the cooling device 3 (see fig. 7 (b)). The filter member 22 may be attached to the cooling device 3 again after being cleaned, for example. Alternatively, another new filter member 22 may be attached to the cooling device 3. In this way, the filter member 22 is attached and detached.

Further, the operator may perform, for example, cleaning of the spinneret 13 in the working space Sw together with the adjustment of the slow cooling section 4 and/or the attachment/detachment of the filter member 22.

After that, the operator operates the cylinder 28 to return the cooling device 3 and the gradually cooling unit 4 from the 2 nd position to the 1 st position. Thereby, the length L of the slow cooling space Ss in the vertical direction is changed from, for example, the length L1 before adjustment (see fig. 5) to the length L2 after adjustment (see fig. 8). Further, the block member 30 and the spacer 35 are urged upward by the cylinder 28. Thus, the gap between the block member 30 and the lower surface of the spinning device 2 is effectively sealed by the gasket 35. Further, substantially the entire upper surface of the spacer 35 is in contact with the lower surface of the frame 10 of the spinning device 2. When the cooling device 3 and the slow cooling portion 4 are returned from the 2 nd position to the 1 st position, it is not necessary to perform precise positioning of the spacers 35.

As described above, the plurality of cooling drums 21 can be surrounded by one block member 30. Further, the adjustment section 40 adjusts the relative positions of the block member 30 and the plurality of cooling tubes 21 in the vertical direction, thereby making it possible to change the vertical distance between the spinneret 13 and the cooling device 3 (that is, the vertical length of the slow cooling space Ss). Therefore, even when the number of yarns Y that can be spun in the spinning device 1 is large, the length L in the vertical direction of the slow cooling space Ss can be changed by a small number of members.

Further, the gasket 35 as the sealing member can reliably prevent the outside air from entering the slow cooling space Ss through the gap between the spinning device 2 and the block member 30. Therefore, the temperature fluctuation of the spinneret 13 due to the outside air can be suppressed.

Further, the spacer 35 is a heat insulating member. Therefore, heat can be suppressed from moving between the spinning device 2 and the block member 30. This can further suppress temperature fluctuations of the spinneret 13.

Further, by moving the cooling device 3 to the 2 nd position, the spinneret 13, the cooling cylinder 21, and the adjusting section 40 can be operated in the operation space Sw. Therefore, good workability can be ensured.

When the cooling device 3 is moved to the 2 nd position, if the block member 30 is configured to move relative to the cooling device 3, the block member 30 is temporarily separated from the plurality of cooling cylinders 21. Therefore, when the cooling device 3 is moved from the 2 nd position to the 1 st position, it is necessary to align the plurality of surrounding surfaces 33 with the plurality of cooling cylinders 21, which may take time and labor. In this regard, in the present embodiment, the block member 30 moves integrally with the cooling device 3. Therefore, when the cooling device 3 is moved, the plurality of surrounding surfaces 33 can be maintained in a state of surrounding the plurality of cooling cylinders 21. Therefore, the need for the above-described alignment can be avoided.

In addition, in the present embodiment, the block member 30 can be easily removed from the placement portion 41 as needed.

Further, the position of the placement portion 41 in the vertical direction can be precisely adjusted by a simple structure using the bolt 42. In other words, with a simple configuration, the relative positions of the block member 30 and the plurality of cooling cylinders 21 can be precisely adjusted.

The adjustment portion 40 has a base portion (cover member 20b) to 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 unit 41 can be moved in the vertical direction with a simple structure.

The mounting portion 41 can be formed by using a generally inexpensive nut 44. Thus, the cost of the parts can be reduced.

In a state where the block member 30 is placed on the placement portion 41, a tool (a hexagon wrench Hw in the present embodiment) for turning the bolt 42 can be made to pass through the 2 nd through hole 32, and the tool can be made to approach the bolt 42. Therefore, the bolt 42 can be rotated in a state where the block member 30 is placed on the placement portion 41. That is, when the bolt 42 is rotated, it is not necessary to remove the block member 30 from the placement portion 41. Therefore, the man-hours required for manually adjusting the relative position between the block member 30 and the cooling cylinder 21 can be reduced.

Further, the block member 30 is placed on the plurality of placement portions 41. Therefore, the balance of the block member 30 can be maintained well.

Further, by changing the state of the cover 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.

Further, the filter member 22 can be pressed from above by the cover member 52 having a simple structure, and the filter member 22 can be detached from the cooling device 3.

Next, a modification of the above embodiment will be described. However, the same reference numerals are given to members having the same configurations as those of the above-described embodiment, and the description thereof will be omitted as appropriate.

(1) The spinning device 1 may include a plurality of covering members 60 shown in fig. 9. The covering member 60 is a member that covers a lower end portion 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 an extending portion 23E of the cooling cylinder 21 (upper cylinder member 23) that extends downward from the lower surface of the block member 30. That is, the plurality of covering members 60 may be, for example, rubber rings configured to surround the extension portions 23E. Thereby, the covering member 60 can cover the gap 34 when the yarn Y is produced. Therefore, even when the gap 34 is large, the inflow of the outside air into the slow cooling space Ss can be prevented. Therefore, both ease of position adjustment of the block member 30 and good yarn quality can be achieved. 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 cover member 60 may be a ring member having a plurality of ring pieces (not shown) that are configured to be separable in the circumferential direction, for example. This prevents the cover member 60 from interfering with the adjustment operation. In this modification, a single 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 several gaps 34 among the plurality of gaps 34 may be provided.

(2) In the embodiments described above, the lid member 52 of the cooling cylinder 21 is screwed to the outer peripheral member 51, but the present invention is not limited thereto. The cover member 52 and the outer peripheral member 51 may have magnets, not shown, for example. Thus, the cover member 52 can be detachably attached to the outer peripheral member 51 by magnetic force. The cover member 52 is annular, but is not limited thereto. The cover member 52 may have any shape as long as it is configured to change the state between the pressed state and the released state.

(3) In the embodiments described above, the cover member 52 is detachable from the outer peripheral member 51, but the present invention is not limited to this. The cover member 52 may be fixed to the outer peripheral member 51 by welding, for example, so as not to be detachable. Alternatively, the cooling cylinder 21 may be formed of one piece. In these cases, when the filter member 22 is attached and detached, the cover member 20b of the case 20 needs to be separated from the main body 20 a. As a preparatory operation therefor, it is necessary to lift the block member 30 and remove it from the plurality of placement portions 41.

(4) The horizontal positions of the plurality of placement portions 41 are not limited to the above. In consideration of the workability of height adjustment of the block member 30, it is also possible to design that the plurality of placement portions 41 are arranged at the optimum positions.

(5) The 2 nd through hole 32 of the block member 30 does not necessarily penetrate the block member 30 in the vertical direction. The 2 nd through hole 32 may extend, for example, in an oblique direction as long as it is formed so that a tool can be brought close to the bolt 42. Alternatively, the 2 nd through hole 32 is not necessarily formed. However, in this case, the block member 30 needs to be moved away from the plurality of placement portions 41 during the adjustment work.

(6) In the embodiments described above, the adjustment unit 40 has the plurality of placement units 41, but the present invention is not limited thereto. The adjustment part 40 may have a large placement part (not shown). Such a mounting portion may be supported by 1 or more bolts 42.

(7) In the above-described embodiments, the mounting portion 41 has the nut 44, but the present invention is not limited thereto. The mounting portion 41 may be formed of a member other than the nut 44. For example, in the embodiments described above, the bolt 42 has no head, but is not limited thereto. The bolt 42 may also have a head formed with a hexagonal hole, for example. The mounting portion of the present invention may be constituted by the head portion. Further, a threaded hole (not shown) having a shape other than a hexagonal hole may be formed in the bolt 42. In the case where the bolt 42 has a head portion, it is not always necessary to form a screw hole in the head portion. That is, for example, a known hexagonal bolt having a substantially hexagonal prism-shaped head portion may correspond to both the mounting portion and the bolt of the present invention. However, in this case, the block member 30 needs to be moved away from the plurality of placement portions 41 during the adjustment work.

(8) The configuration of the base portion (cover member 20b) is not limited to the above configuration. In the above example, the nut 43b is fixed to the cover member 20b, but the present invention is not limited thereto. For example, a female screw may be formed in the insertion hole 43a formed in the cover member 20 b. Thereby, the bolt 42 can be screwed into the insertion hole 43 a. Alternatively, the base portion may be formed of a member (not shown) different from the cover member 20 b.

(9) In the embodiments described above, the adjustment portion 40 has the bolt 42 extending in the vertical direction, and the placement portion 41 moves in the vertical direction integrally with the bolt 42. But is not limited thereto. The adjusting unit (not shown) may have a rack and pinion mechanism including a rack (not shown) and a pinion (not shown), for example. More specifically, a mounting portion (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. The rack (placement unit) may be moved in the vertical direction by rotating the pinion gear. Alternatively, the adjusting unit (not shown) may have a jack (a diamond-shaped telescopic jack or the like) not shown. For example, two diamond-shaped telescopic jacks (not shown) may be provided between the block member 30 and the casing 20 (cover member 20b) in the vertical direction. The two diamond-shaped frame telescopic jacks may be disposed at both ends of the support block member 30 in the longitudinal direction (left-right direction).

(10) In the embodiments described above, the adjustment unit 40 has the placement unit 41, and the block member 30 is placed on the placement unit 41. That is, the block member 30 can be easily separated from the adjustment portion 40 and the cooling device 3. But is not limited thereto. For example, the block member 30 and the adjustment portion 40 may be configured to be difficult to separate or impossible to separate.

(11) In the embodiments described above, the block member 30 is configured to move integrally with the cooling device 3 when the cylinder 28 is operated. But is not limited thereto. The block member 30 may be fixed to the spinning device 2, for example. That is, the slow cooling unit 4 may be configured such that the adjusting unit 40 and the block member 30 are separated from each other when the cylinder 28 moves the cooling device 3 from the 1 st position to the 2 nd position. Further, the spacer 35 is not necessarily provided between the spinning device 2 and the block member 30.

(12) In the embodiments up to this point, the working space Sw is formed when the cylinder 28 moves the cooling device 3 from the 1 st position to the 2 nd position. That is, in the working space Sw, the plurality of spinning nozzles 13, the plurality of cooling tubes 21, and the adjusting section 40 can be operated. But is not limited thereto. For example, in the working space Sw, only the plurality of cooling cylinders 21 and the adjustment unit 40 may be operated.

(13) In the embodiments described above, the air cylinder 28 is provided as a moving mechanism for moving the cooling device 3 in the vertical direction. But is not limited thereto. Instead of the air cylinder 28, for example, a hydraulic cylinder (not shown) or a ball screw mechanism (not shown) may be provided.

(14) In the embodiments described above, the adjustment unit 40 is manually operated by an operator. But is not limited thereto. The adjustment unit 40 may have an electric linear actuator, not shown, for example. In this case, a moving mechanism for moving the cooling device 3 in the vertical direction is not necessarily provided. 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.

(15) In the embodiments described above, the material of the block member 30 is an aluminum alloy, but the material is not limited to this. The block member 30 may be formed of a metal material other than aluminum alloy. Alternatively, the block member 30 may be formed of a non-metallic material. Further, the block member 30 is not necessarily solid. The block member 30 may also be hollow.

(16) In order to improve workability in attaching and detaching the filter member 22, the cooling device 3 may be configured as follows. For example, 1 or more openings (not shown) may be provided in the front surface of the main body 20a of the

case

20, and 1 or more covers (not shown) that block the 1 or more openings may be attached. Each cover preferably extends in the left-right direction (the direction in which the plurality of cooling cylinders 21 are arranged). Each cover is preferably openable and closable or detachable from the case 20. In such a configuration, the operator can insert his or her hand into the internal space of the case 20 from the front side by moving each cover with respect to the opening closed by each cover. Thus, for example, when the filter member 22 is attached to the case 20, the operator can easily access the side surface of the filter member 22. Thus, the position of the filter member 22 can be easily fine-adjusted.
