The machine includes a false-twisting device for individually twisting the multiple filaments, a cooling device positioned upstream of the false-twisting device in the direction of filament travel, and a heating device positioned upstream of the cooling device in the same direction. The multiple filaments are heat-set by the heating device while being individually twisted by the multiple false-twisting devices, and then cooled by the cooling device. This sets the curl of the filaments, producing a filament with a bulky texture.

[0003] Patent Document 1: Japanese Patent No. 4462751

[0004] In recent years, there has been a demand for false-twisting machines capable of processing thicker yarns compared to the past. On the other hand, it is also necessary to consider the number of yarns that can be false-twisted simultaneously (hereinafter referred to as production efficiency) and to suppress the increase in yarn quality deviation between multiple yarns (hereinafter referred to as homogeneity). Summary of the Invention

[0005] The purpose of this invention is to suppress the damage to production efficiency and homogeneity, and to ensure good yarn quality, even when false twisting is performed on thicker yarns.

[0006] The false twisting processing mechanism of the first invention is capable of simultaneously performing false twisting processing on at least a first filament and a second filament traveling in the same direction. It is characterized by comprising: a false twisting device configured to twist the first filament and the second filament; and a cooling device disposed upstream of the false twisting device in the filament traveling direction of the first filament and the second filament, configured to cool the first filament and the second filament. The false twisting device has a circular plate configured to rotate about a predetermined direction as its rotation axis, a first belt unit disposed on one side of the circular plate in the predetermined direction, and a second belt unit disposed on the other side of the circular plate in the predetermined direction. The circular plate has a first contact surface at the end disposed on one side in the predetermined direction and a second contact surface at the end disposed on the other side in the predetermined direction. The first belt unit is configured to have a first belt member that can move while in contact with the first filament, and to twist the first filament by clamping it between the first contact surface and the first belt member. The second belt unit is configured to have a second belt member that can move while in contact with the second filament, and to twist the second filament by clamping it between the second contact surface and the second belt member. The cooling device includes: a cooling unit having a first cooling space for cooling the first filament and a second cooling space arranged side by side with the first cooling space for cooling the second filament; and an air intake pipe having an air intake space connected to the first cooling space and the second cooling space for supplying cooling air to the first cooling space and the second cooling space.

[0007] In the false-twisting apparatus of the false-twisting machine of the present invention, the first filament is clamped between the first belt member and the first contact surface, and the second filament is clamped between the second belt member and the second contact surface. This allows for reliable twisting of both the first and second filaments. Furthermore, since the first and second contact surfaces are formed on the same circular plate, the gap between the first and second filaments can be reduced in the false-twisting apparatus. Therefore, more filaments can be twisted in a smaller space. Moreover, in this false-twisting apparatus, the position where the first filament is false-twisted is close to the position where the second filament is false-twisted. Therefore, it is possible to suppress a large difference in the filament channels of the first and second filaments (and, due to this difference, to prevent deviations in filament quality between the first and second filaments).

[0008] Furthermore, in the cooling device of the false twisting machine of the present invention, the first and second filaments can be reliably cooled by cooling air. Moreover, since the first and second cooling spaces are formed within the same cooling unit, the gap between the first and second filaments can be reduced in the cooling device. Therefore, more filaments can be cooled in a smaller space. Furthermore, as described above, by reducing the gap between the first and second filaments, the significant difference between the filament channels of the first and second filaments (and the resulting deviation in filament quality) can be suppressed.

[0009] As mentioned above, even when false twisting is applied to thicker yarns, it is possible to suppress the impairment of production efficiency and homogeneity, and to ensure good yarn quality.

[0010] The false twisting processing machine of the second invention is characterized in that, in the first invention, the first cooling space and the second cooling space are arranged side by side in the specified direction.

[0011] In this invention, when the first and second yarns are fed from the cooling device to the false twisting device, the first and second yarns can be maintained in a side-by-side arrangement in a predetermined direction. Therefore, for example, compared to a case where the first and second cooling spaces are arranged side-by-side in a direction different from the predetermined direction, it is possible to further suppress the yarn passages of the first and second yarns being different. Consequently, the deviation in yarn quality between the first and second yarns can be effectively reduced.

[0012] The false twisting processing machine of the third invention is characterized in that, in the second invention described above, when the distance between the upstream end of the first cooling space in the direction of the yarn travel and the upstream end of the second cooling space in the direction of the yarn travel in a predetermined direction is set as WC1, and the distance between the downstream end of the first cooling space in the direction of the yarn travel and the downstream end of the second cooling space in the direction of the yarn travel in a predetermined direction is set as WC2, WC2≤WC1.

[0013] In this invention, because WC2 is small, bending of the first and second yarns can be suppressed when they are fed from the cooling device to the false twisting device. Therefore, the reduction in yarn quality can be suppressed.

[0014] The false twisting machine of the fourth invention is characterized in that, in the second or third invention described above, it comprises: an upstream guide wire member disposed on the upstream side of the cooling device in the direction of wire travel; and a downstream guide wire member disposed on the downstream side of the cooling device in the direction of wire travel. The upstream guide wire member is configured such that the interval between the first wire and the second wire in the predetermined direction is defined as W1, and the downstream guide wire member is configured such that the interval between the first wire and the second wire in the predetermined direction is defined as W2. When the interval between the upstream end of the first cooling space in the direction of wire travel and the upstream end of the second cooling space in the direction of wire travel is set to WC1 in the predetermined direction, and the interval between the downstream end of the first cooling space in the direction of wire travel and the downstream end of the second cooling space in the direction of wire travel is set to WC2 in the predetermined direction, W2≤WC2≤WC1≤W1, or W1≤WC1≤WC2≤W2.

[0015] In this invention, when hanging wires onto the cooling unit, the first and second wires can be kept approximately straight while the wire hanging operation is performed. That is, when hanging wires onto the cooling unit, it is almost unnecessary to bend the first and second wires. Therefore, it is easy to hang the first and second wires onto the cooling unit simultaneously.

[0016] The false twisting processing machine of the fifth invention is characterized in that, in any one of the second to fourth inventions above, the cooling unit has a separating member that separates the first cooling space and the second cooling space in a predetermined direction.

[0017] The first cooling space and the second cooling space do not necessarily have to be separated, but in this case, the first and second threads may become entangled for some reason. In this invention, since the first cooling space and the second cooling space are separated by a separating component, this problem can be reliably avoided.

[0018] The false twisting processing machine of the sixth invention is characterized in that, in the fifth invention, the suction space extends along the specified direction, and the first cooling space and the second cooling space are respectively connected to the suction space.

[0019] In this invention, the first cooling space and the second cooling space are respectively connected to an air intake space extending along a predetermined direction (i.e., connected in parallel). Therefore, cooling air can be supplied to the first cooling space and the second cooling space substantially uniformly through a simple structure.

[0020] The false twisting processing machine of the seventh invention is characterized in that, in the fifth or sixth invention described above, the separating member has: a first separating portion having a first separating surface disposed on one side of the first separating surface in the predetermined direction to form the first cooling space; and a second separating portion having a second separating surface disposed on the other side of the predetermined direction to form the second cooling space; the cooling unit has: a first wall member having a first wall surface disposed on one side of the first separating surface in the predetermined direction and used to form the first cooling space; and a second wall member having a second wall surface disposed on the other side of the second separating surface in the predetermined direction and used to form the second cooling space.

[0021] In this invention, a first cooling space is formed by the first separating surface of the separating member and the first wall surface of the first wall member. Furthermore, a second cooling space is formed by the second separating surface of the separating member and the second wall surface of the second wall member. Therefore, both the first and second cooling spaces can be formed with a simple structure.

[0022] The false twisting processing machine of the eighth invention is characterized in that, in the seventh invention, the first dividing surface is configured to face the first wall surface in the specified direction, and the second dividing surface is configured to face the second wall surface in the specified direction.

[0023] For example, when the first yarn is twisted by the false twisting device and comes into contact with the wall forming the first cooling space, the first yarn may roll along the wall and fall out of the first cooling space. This possibility is increased, especially when the inlet for the first yarn to enter the first cooling space is large. The same applies to the second cooling space. In this invention, the first separating surface is configured to face the first wall surface in a predetermined direction (i.e., the two surfaces are substantially parallel to each other). This narrows the aforementioned inlet of the first cooling space. The same applies to the second cooling space. Therefore, it is possible to suppress the first yarn from falling out of the first cooling space, and it is also possible to suppress the second yarn from falling out of the second cooling space.

[0024] The false twisting machine of the ninth invention is characterized in that, in the seventh or eighth invention described above, the cooling unit comprises: a first wire guide disposed in the predetermined direction between the first dividing surface and the first wall surface, guiding the first wire to the downstream side in the wire travel direction; and a second wire guide disposed in the predetermined direction between the second dividing surface and the second wall surface, guiding the second wire to the downstream side in the wire travel direction.

[0025] The cooling unit can, for example, be configured to cool the yarn using cooling air and the walls and partitions cooled by the cooling air. However, in such a configuration where the yarn actively contacts the walls and partitions, the yarn is prone to rolling along the walls or partitions when twisted by the false twisting device. Therefore, the possibility of the yarn falling out of the cooling space increases. Regarding this, in the present invention, the first yarn is guided downstream in the yarn travel direction by the first yarn guide, and the second yarn is guided downstream in the yarn travel direction by the second yarn guide. That is, the cooling unit is not configured to actively contact the yarn with the partitions and walls. Therefore, the aforementioned problems can be suppressed.

[0026] The false twisting processing machine of the 10th invention is characterized in that, in any one of the 7th to 9th inventions, the first wall component and the second wall component are mounted on the air intake pipe, and at least one of the first wall component and the second wall component supports the separating component.

[0027] The cooling unit can be designed such that the smaller the partition member is in a specified direction, the shorter the distance between the first cooling space and the second cooling space in that direction. That is, the gap between the first and second wires can be narrowed. However, if the partition member is very small in the specified direction, it may be impossible to install the partition member into the intake pipe (e.g., by threaded fixing). In this invention, the partition member can be supported by at least one of the first wall member and the second wall member. Therefore, even if it is impossible to install the partition member into the intake pipe, the partition member can still be configured normally.

[0028] The false twisting processing machine of the 11th invention is characterized in that, in the aforementioned 10th invention, it is configured such that both the first wall member and the second wall member support the aforementioned separating member.

[0029] In this invention, the partition member is supported at both ends by the first wall member and the second wall member. Therefore, the partition member can be stably supported.

[0030] The false twisting processing machine of the 12th invention is characterized in that, in any one of the 7th to 11th inventions above, at least the separating member is configured to be movable relative to the first wall member and the second wall member.

[0031] Normally, an oil is applied to the false-twisted yarn to facilitate its smooth movement. When this oil adheres to the cooling unit, it contaminates the unit, necessitating proper cleaning of the components constituting the cooling unit. In this invention, at least the separating member is configured to be movable relative to the first wall member and the second wall member. Movable relative to each other includes, for example, the first wall member and the second wall member being movable relative to the separating member. This ensures ample space for cleaning these components, thereby improving the efficiency of cleaning and other operations.

[0032] The false twisting processing machine of the 13th invention is characterized in that, in the 12th invention described above, the position of one of the first wall component and the second wall component is fixed relative to the air intake pipe, and the other of the first wall component and the second wall component, as well as the separating component, are movable relative to one of the first wall component and the second wall component.

[0033] For ease of explanation, one of the first wall component and the second wall component described above will be referred to as a fixed wall component. In this invention, other cooling units can be provided near the fixed wall component, configured symmetrically with respect to the cooling unit line with a straight line approximately parallel to the length direction of the cooling unit as the axis of symmetry. Even with such other cooling units provided, the two adjacent fixed wall components will not move. Therefore, when the components are moved during cleaning, interference between the components can be avoided.

[0034] The false twisting processing machine of the 14th invention is characterized in that, in the 12th or 13th invention described above, the separating member is configured to be detachable from the cooling unit.

[0035] In this invention, since the separating component can be completely separated from the cooling unit, the efficiency of cleaning and other operations can be greatly improved.

[0036] The false twisting machine of the 15th invention is characterized in that, in any one of the 7th to 14th inventions above, when the direction orthogonal to both the length direction of the cooling unit and the predetermined direction is set as the height direction, the dividing member has: a first wire insertion guide portion that protrudes into the working space side of the cooling device for wire hanging operation, at least in the height direction; and a second wire insertion guide portion that protrudes into the working space side of the cooling device, at least in the height direction.

[0037] In this invention, during the wire-hanging operation, the first wire can move along the first wire insertion guide section, and the second wire can move along the second wire insertion guide section. This improves the success rate of the wire-hanging operation.

[0038] The false twisting processing machine of the 16th invention is characterized in that, in the 15th invention described above, it includes a heating device disposed upstream of the cooling device in the direction of yarn travel, configured to heat the first yarn and the second yarn. The false twisting device, the cooling device, and the heating device are disposed above the working space. The upstream end of the heating device in the direction of yarn travel is configured to be vertically away from the cooling device upward compared to the downstream end of the heating device in the direction of yarn travel.

[0039] In this invention, the upstream end of the heating device in the direction of yarn travel is positioned high in the vertical direction, making it difficult for the operator to manually hook the yarn onto the heating device. In this case, generally, after hooking the yarn onto the false twisting device, a device for moving the yarn upwards (e.g., an air jet device) is used to hook the yarn onto both the cooling and heating devices in one go. When performing this yarn-hooking operation, it is particularly effective to improve the success rate by inserting the first yarn into the guide section and then the second yarn into the guide section.

Detailed Implementation

[0055] Next, embodiments of the present invention will be described. Figure 1 The direction perpendicular to the paper surface is defined as the length direction of the machine body (the specified direction in this invention). For ease of explanation, [the following is omitted]. Figure 1 The front side of the paper and Figure 2 The left side of the paper is set as one side along the length of the machine body. Figure 1 The inside of the paper and Figure 2 The right side of the paper is designated as the other side along the length of the machine body. Figure 1 The left-right direction of the paper is defined as the width direction of the machine body. The direction orthogonal to both the length and width directions of the machine body is defined as the vertical direction (up-down direction) of gravity. The direction in which multiple threads Y (described later) travel side by side is defined as the direction of thread travel.

[0056] (The overall structure of a false twisting processing machine)

[0057] First, refer to Figure 1 as well as Figure 2 The overall configuration of the false twisting processing machine 1 of this embodiment will be described. Figure 1 This is a side view of the false twisting machine 1. Figure 2 This is a schematic diagram of unfolding the false twisting processing machine 1 along the path (silk channel) of the silk thread Y.

[0058] The false-twisting machine 1 is configured to simultaneously perform false-twisting processing on multiple filaments Y made of synthetic fibers (e.g., polyester). The multiple filaments Y are, for example, multifilaments composed of multiple filaments. Alternatively, each filament Y may be composed of a single filament. The false-twisting machine 1 includes a feeding section 2, a processing section 3, and a winding section 4. The feeding section 2 is configured to supply multiple filaments Y. The processing section 3 is configured to pull out multiple filaments Y from the feeding section 2 for false-twisting processing. The winding section 4 is configured to wind the multiple filaments Y processed by the processing section 3 into a winding bobbin Bw. Multiple components of the feeding section 2, processing section 3, and winding section 4 are arranged along the length of the machine body (see reference). Figure 2 The length direction of the machine body is the same as the travel plane of the yarn Y formed by the yarn channel from the yarn supply section 2 through the processing section 3 to the winding section 4. Figure 1 (The direction is perpendicular to the paper).

[0059] The yarn feeding section 2 has a bobbin 7 that holds multiple yarn feed packages Ps and supplies multiple yarns Y to the processing section 3. The processing section 3 is configured to pull out multiple yarns Y from the yarn feeding section 2 for processing. The processing section 3 is configured such that, starting from the upstream side in the yarn travel direction, a first yarn feeding roller 11, a twist guide 12, a first heating device 13 (the heating device of the present invention), a cooling device 14, a false twisting device 15, a second yarn feeding roller 16, a yarn bundling device 17, a third yarn feeding roller 18, a second heating device 19, and a fourth yarn feeding roller 20 are arranged sequentially. The take-up section 4 has multiple take-up devices 21. Each take-up device 21 takes the yarns Y that have been false twisted by the processing section 3 onto one or more take-up bobbins Bw to form one or more take-up packages Pw.

[0060] The false twisting processing machine 1 includes a main body 8 and a winding table 9 arranged at intervals along the width direction of the machine body. The main body 8 and the winding table 9 are configured to extend to approximately the same length along the length direction of the machine body. The main body 8 and the winding table 9 are arranged opposite each other in the width direction of the machine body. A working space Sw (see reference) is formed between the main body 8 and the winding table 9 for the operator to perform operations such as wire winding. Figure 1The false twisting machine 1 has a unit unit, referred to as a span, comprising a set of main bodies 8 and a take-up table 9. Within a span, the devices are configured to simultaneously perform false twisting on multiple yarns Y traveling side-by-side in the length direction of the machine body. In the false twisting machine 1, the span is symmetrically arranged on the paper surface about the centerline C of the main body 8 in the width direction (the main body 8 is shared in both left and right spans). Furthermore, multiple spans are arranged along the length direction of the machine body.

[0061] (Composition of the machining department)

[0062] Reference Figure 1 as well as Figure 2 The configuration of the processing section 3 will be described. The first feed roller 11 is configured to feed the unwound yarn Y from the feed package Ps installed in the feed section 2 to the first heating device 13. Figure 2 As shown, the first feed roller 11 is configured, for example, to feed two yarns Y to the first heating device 13, but is not limited thereto. The anti-twist guide 12 is configured to prevent the twist imparted to the yarn Y by the false twist device 15 from propagating upstream of the yarn travel direction of the anti-twist guide 12.

[0063] The first heating device 13 is configured to heat the yarn Y fed from the first feed roller 11. The first heating device 13 is inclined such that the upstream end in the yarn travel direction is located above the downstream end (see reference). Figure 1 In other words, the upstream end of the first heating device 13 in the direction of wire travel is configured to be located further upward from the cooling device 14 in the vertical direction compared to the downstream end of the first heating device 13 in the direction of wire travel. Figure 2 As shown, the first heating device 13 is configured, for example, to heat four filaments Y, but is not limited thereto.

[0064] The cooling device 14 is configured to cool the yarn Y heated by the first heating device 13. Details regarding the cooling device 14 will be described later. The false twisting device 15 is located downstream of the cooling device 14 in the yarn travel direction and is configured to twist two yarns Y (the first yarn Ya and the second yarn Yb). Details regarding the false twisting device 15 will be described later.

[0065] The second feed roller 16 is configured to feed the yarn Y, processed by the false twisting device 15, to the yarn doubling device 17. The feed speed of the second feed roller 16 to the yarn Y is faster than that of the first feed roller 11. As a result, the yarn Y is stretched between the first feed roller 11 and the second feed roller 16.

[0066] The yarn-coupling device 17 is configured to couple the first yarn Ya and the second yarn Yb to form yarn Yc. The yarn-coupling device 17 has two interlacing nozzles 17a and 17b (see reference). Figure 2 The yarn-coupling device 17, for example, is used for the first yarn Ya and the second yarn Yb passing inside the interlacing nozzle 17a (see reference). Figure 2 Air is ejected from the left side of the paper, and the first thread Ya and the second thread Yb are intertwined by the airflow to form thread Yc. The intertwining device 17 can also guide the first thread Ya and the second thread Yb directly downstream in the thread travel direction without intertwining them. In this case, the first thread Ya passes inside the intertwining nozzle 17a, and the second thread Yb passes inside the intertwining nozzle 17b (see reference). Figure 2 (The right side of the paper). Alternatively, instead of the yarn-coupling device 17 with interlacing nozzles 17a and 17b, a yarn-coupling section (not shown) with a yarn guide or a yarn feed roller can be provided. The yarn-coupling section can also yarn-couple two yarns Y through the yarn guide or the yarn feed roller, or it can guide the two yarns Y directly downstream in the yarn travel direction without yarn-coupling.

[0067] The third feed roller 18 is configured to feed the yarn Y, which is traveling downstream of the yarn traveling in the yarn travel direction from the yarn paralleling device 17, to the second heating device 19. For example... Figure 2 As shown, the third feed roller 18 is configured, for example, to feed two yarns Y to the second heating device 19, but is not limited thereto. Furthermore, the feed speed of the third feed roller 18 to the yarn Y is slower than the feed speed of the second feed roller 16 to the yarn Y. Therefore, the yarn Y is slack between the second feed roller 16 and the third feed roller 18. The second heating device 19 is configured to heat the yarn Y fed from the third feed roller 18. The second heating device 19 extends vertically, with one device provided in each span. The fourth feed roller 20 is configured to feed the yarn Y heated by the second heating device 19 to the winding device 21. Figure 2 As shown, the fourth feed roller 20 is configured, for example, to feed two yarns Y to the winding device 21, but is not limited thereto. The feed speed of the fourth feed roller 20 to the yarn Y is slower than the feed speed of the third feed roller 18 to the yarn Y. Therefore, the yarn Y is slack between the third feed roller 18 and the fourth feed roller 20.

[0068] In the processing section 3 configured as described above, the yarn Y stretched between the first feed roller 11 and the second feed roller 16 is twisted by the false twisting device 15. The twist formed by the false twisting device 15 propagates to the anti-twist guide 12, but does not propagate upstream of the yarn travel direction of the anti-twist guide 12. The yarn Y, which is stretched and twisted at the same time, is heat-set by the first heating device 13 and then cooled by the cooling device 14. The yarn Y downstream of the false twisting device 15 in the yarn travel direction is untwisted, but the yarn Y is maintained in a false twisted wavy state by the heat setting. The two yarns Y (the first yarn Ya and the second yarn Yb) that have been false twisted are slack between the second feed roller 16 and the third feed roller 18 and then plied by the pliing device 17 or guided directly downstream in the yarn travel direction without being plied. Furthermore, while the yarn Y is slack between the third feed roller 18 and the fourth feed roller 20, it is heat-treated by the second heating device 19. Finally, the yarn Y (ya or yc, the first yarn Ya and the second yarn Yb) fed from the fourth feed roller 20 is wound up by the winding device 21. Thus, one or two winding packages Pw are formed in each winding device 21.

[0069] (Structure of the winding section)

[0070] Reference Figure 2 The configuration of the winding unit 4 will be described. The winding unit 4 has multiple winding devices 21. Each winding device 21 is configured, for example, to wind the yarn Y onto one or two winding bobbins Bw. The winding device 21 has a fulcrum guide 22, a traverse device 23, and a cradle 24. The fulcrum guide 22 is a guide that serves as the fulcrum when the yarn Y traverses. For example, three fulcrum guides 22 are provided in each winding device 21 (see reference). Figure 2 For example, when guiding a yarn Yc formed into a single strand by the yarn-coupling device 17, the yarn Y is hooked onto the centrally located fulcrum guide 22 among the three fulcrum guides (see reference). Figure 2 (The left side of the paper). Furthermore, when guiding two uncoiled yarns Y directly fed to the table, yarns Y are hooked onto two of the two end-point guides 22 of the three guides 22 (see reference). Figure 2(The right side of the paper). The traversing device 23 is configured to traverse the yarn Y via the traversing guide 25. The number of traversing guides 25 can be varied depending on the number of yarns Y traversing. The cradle 24 is configured to support one or two take-up bobbins Bw so that they can rotate freely. A contact roller 26 is arranged near the cradle 24. The contact roller 26 contacts the surface of one or two take-up packages Pw and applies contact pressure. In the take-up section 4 configured as described above, the yarn Y fed from the fourth feed roller 20 is taken up by each take-up device 21 onto one or two take-up bobbins Bw to form one or two take-up packages Pw. In addition, the configuration of the take-up device 21 is not limited to the above configuration. For example, the take-up device 21 may also be configured to be able to form three or more take-up packages Pw at the same time. Alternatively, the take-up section 4 may have the same number of take-up devices (not shown) as the number of yarns Y supplied from the feed section 2. Each of these winding devices can also be configured to wind up one thread Y.

[0071] In recent years, there has been a demand for the ability to perform false twisting on thicker yarns Y compared to the past. On the other hand, it is also necessary to consider the number of yarns Y that can be false twisted simultaneously (hereinafter referred to as production efficiency) and to suppress the increase in yarn quality deviation among multiple yarns Y (hereinafter referred to as homogeneity). Therefore, in this embodiment, in order to suppress the impairment of production efficiency and homogeneity and ensure good yarn quality even when performing false twisting on thicker yarns Y, the processing unit 3 has the following configuration.

[0072] (More detailed composition of the machining department)

[0073] Next, a more detailed explanation of the structure of machining section 3 will be provided. First, refer to... Figures 3-5 A more detailed description will be given of the layout of the first heating device 13, the cooling device 14, and the false twisting device 15. Figure 3 yes Figure 1 III-direction view. Figure 4 This refers to the upstream end and its vicinity in the direction of the wire travel of the cooling device 14. Figure 3 A magnified view of a portion of the image. Figure 5 This refers to the downstream end and its vicinity in the direction of the wire travel of the cooling device 14. Figure 3 A partial enlarged view. In this embodiment, the first heating device 13, the cooling device 14, and the false twisting device 15 are arranged above the working space Sw.

[0074] like Figure 3As shown, multiple first heating devices 13 are arranged side-by-side along the length of the machine body. Each of the multiple first heating devices 13 is configured, for example, to simultaneously heat four yarns Y traveling side-by-side along the length of the machine body. A yarn guide G1 (see reference 14) is provided between the first heating device 13 and the cooling device 14 (i.e., upstream of the cooling device 14 in the yarn travel direction). Figure 4 (The upstream wire guide component of the present invention). The wire guide G1 is configured to guide the above-mentioned four wires Y downstream in the wire travel direction. The spacing (interval W1) of the four wires Y guided by the wire guide G1 in the length direction of the machine body. (Refer to...) Figure 4 For example, it is specified as 14mm. However, the size of the interval W1 is not limited to this.

[0075] Cooling device 14 is a non-contact device that cools multiple filaments Y using cooling air (details will be described later). Figure 3 As shown, the cooling device 14 has multiple cooling units 31 and suction pipes 32 connected to the multiple cooling units 31. The cooling device 14 uses a suction device (not shown) to draw gas from the suction pipes 32 into multiple cooling spaces S (see reference numerals) formed in the multiple cooling units 31. Figure 4 as well as Figure 5 Cooling air is supplied. This cooling air is used to cool multiple filaments Y.

[0076] Multiple cooling units 31 are arranged side-by-side along the length of the machine body. The multiple cooling units 31 are mounted on the intake duct 32. Each of the multiple cooling units 31 extends along a direction intersecting (approximately orthogonal) the length of the machine body. Each cooling unit 31 may also extend in a generally straight line, but is not limited to this (for example, it may be curved). Each cooling unit 31 is configured to cool two wires Y (a first wire and Yb second wire). Each cooling unit 31 has a first cooling space Sa for cooling the first wire Ya and a second cooling space Sb for cooling the second wire Yb (see reference). Figure 4 as well as Figure 5 The plurality of cooling units 31 includes two cooling units 31A and 31B arranged adjacent to each other in the length direction of the machine body. The two cooling units 31A and 31B are correspondingly arranged with a first heating device 13. The spacing between cooling units 31A and 31B in the length direction of the machine body increases, for example, towards the downstream side in the direction of yarn travel. The two cooling units 31A and 31B are configured to be aligned along a predetermined straight line L (see reference). Figure 3 They are linearly symmetrical about each other, with the axis of symmetry being the axis of symmetry. More details about the cooling unit 31 will be described later.

[0077] The intake duct 32 is configured to supply cooling air to multiple cooling units 31. The intake duct 32 extends along the length of the fuselage. An intake space Ss extending along the length of the fuselage is formed within the intake duct 32. The intake space Ss and the cooling space S (see reference) Figure 4 as well as Figure 5 (Connection). Multiple cooling units 31 are installed on the intake pipe 32.

[0078] like Figure 3 As shown, multiple false twisting devices 15 are arranged side by side along the length of the machine body. Each of the multiple false twisting devices 15 is configured to simultaneously heat two yarns Y (the first yarn Ya and the second yarn Yb) traveling side by side along the length of the machine body. A yarn guide G2 (see reference 15) is provided between the cooling device 14 and the false twisting devices 15 (i.e., downstream of the cooling device 14 in the yarn travel direction). Figure 5 (The downstream wire guide component of the present invention). The wire guide G2 is configured to guide the two wires Y downstream in the wire travel direction. The distance W2 between the two wires Y guided by the wire guide G2 in the length direction of the machine body (refer to...) Figure 5 For example, it is specified as 8mm. However, the size of the interval W2 is not limited to this.

[0079] (Detailed composition of the false twist device)

[0080] Next, refer to Figure 6 as well as Figure 7 The detailed structure of the false twist device 15 will be explained. Figure 6 This indicates the false twisting device 15. Figure 3 A magnified view of a portion of the image. Figure 7 This is a diagram showing the false twist device 15 viewed from one side along the length of the machine body.

[0081] The false twist device 15 is, for example, a known false twist device as described in Japanese Patent Application Publication No. 2018-127731. Figure 6 As shown, the false twisting device 15 includes a circular plate 41 and two belt units 42 (a first belt unit 42a and a second belt unit 42b). The false twisting device 15 is configured to twist a first filament Ya by clamping it between a first contact surface 41a (described later) of the circular plate 41 and a first annular belt 46a (described later) of the first belt unit 42a. Furthermore, the false twisting device 15 is configured to twist a second filament Yb by clamping it between a second contact surface 41b (described later) of the circular plate 41 and a second annular belt 46b (described later) of the second belt unit 42b.

[0082] The circular plate 41 is a component configured to rotate about the length direction of the machine body. The circular plate 41 is, for example, fixed to a common rotating shaft 43 extending along the length direction of the machine body. The common rotating shaft 43 is configured to connect multiple circular plates 41 respectively disposed in multiple false twisting devices 15. The common rotating shaft 43 is driven to rotate, for example, by a motor (not shown). Thus, the circular plate 41 is driven to rotate. A first contact surface 41a for contact with the first yarn Ya is formed on one end face of the circular plate 41 in the length direction of the machine body. A second contact surface 41b for contact with the second yarn Yb is formed on the other end face of the circular plate 41 in the length direction of the machine body.

[0083] The first belt unit 42a is disposed on one side of the circular plate 41 along its length. The first belt unit 42a includes a first drive pulley 44a, a first driven pulley 45a, and a first annular belt 46a (the first belt component of the present invention). The first annular belt 46a is wound onto the first drive pulley 44a and the first driven pulley 45a. A first thread Ya is disposed between the first annular belt 46a and the first contact surface 41a. The rotation axes of the first drive pulley 44a and the first driven pulley 45a extend in a direction substantially orthogonal to the length direction of the body. The rotation axes of the first drive pulley 44a and the first driven pulley 45a are substantially parallel to each other. The first drive pulley 44a and the first driven pulley 45a are arranged side-by-side in a direction substantially orthogonal to a common rotation axis 43.

[0084] The second belt unit 42b is disposed on the other side of the circular plate 41 along its length. The second belt unit 42b has a second drive pulley 44b, a second driven pulley 45b, and a second annular belt 46b (the second belt component of the present invention). The second annular belt 46b is wound onto the second drive pulley 44b and the second driven pulley 45b. A second thread Yb is disposed between the second annular belt 46b and the second contact surface 41b. The rotation axes of the second drive pulley 44b and the second driven pulley 45b extend in a direction substantially parallel to the rotation axes of the first drive pulley 44a and the first driven pulley 45a. The second drive pulley 44b and the second driven pulley 45b are arranged side-by-side in a direction substantially orthogonal to the common rotation axis 43.

[0085] The first drive pulley 44a and the second drive pulley 44b are driven by the drive unit 47 (see reference). Figure 7 Rotary drive. The drive unit 47 is configured to drive the first drive pulley 44a and the second drive pulley 44b to rotate in opposite directions. The drive unit 47 has a drive source (e.g., a motor, not shown), a first power transmission member (not shown) that transmits power from the drive source to the first drive pulley 44a, and a second power transmission member (not shown) that transmits power from the drive source to the second drive pulley 44b.

[0086] When viewed along the length of the machine body, the first belt unit 42a and the second belt unit 42b are configured to substantially overlap each other. Therefore, when viewed along the length of the machine body, the thread channel of the first thread Ya and the thread channel of the second thread Yb in the false twisting device 15 substantially overlap (see reference). Figure 7 ).

[0087] In the false twisting device 15 configured as described above, the first filament Ya is twisted by the first annular belt 46a and the first contact surface 41a. The second filament Yb is twisted by the second annular belt 46b and the second contact surface 41b. Thus, both filaments Y are twisted simultaneously. The first filament Ya and the second filament Yb are twisted in opposite directions. For example, the first filament Ya is subjected to a Z-twist, and the second filament Yb is subjected to an S-twist.

[0088] (Detailed composition of the cooling system)

[0089] Next, mainly refer to Figures 8-11 A more detailed description of the cooling device 14 is provided below. Figure 8 This is a diagram that roughly represents the components constituting the cooling unit 31 (cooling unit 31A), and is derived from... Figure 3 View the diagram of cooling unit 31A from the same direction. That is, Figure 8 This is a diagram showing the cooling unit 31A roughly from below. Figure 9 yes Figure 8 Cross-sectional view of the IX-IX line. Figure 10 This is an explanatory diagram showing the state in which the partition component 53, described later, is removed from the cooling unit 31A. Figure 11 This is a further schematic diagram of the cooling unit 31A to facilitate observation of the cooling space S. As described above, the cooling unit 31A and the cooling unit 31B are configured to be linearly symmetrical to each other (see reference). Figure 3 Therefore, the following will mainly describe the cooling unit 31A in detail and provide a brief description of the cooling unit 31B.

[0090] Will Figure 8 The direction perpendicular to the paper surface is defined as the height direction. The height direction and... Figure 9 as well as Figure 10The vertical direction is parallel to the horizontal direction on the paper. The height direction is orthogonal to the length direction of the machine body. Furthermore, in this embodiment, the height direction has at least a vertical component. In this embodiment, one side of the height direction can also be referred to as the approximately upper side. Furthermore, the other side of the height direction can also be referred to as the approximately lower side. However, it should be noted that the relationship between the height direction and the vertical direction may change depending on the orientation of the cooling device 14. Furthermore, for ease of explanation, the direction orthogonal to both the length direction and the height direction of the machine body is defined as the orthogonal direction. Cooling unit 31A and cooling unit 31B extend at least along the orthogonal direction. In the orthogonal direction, the side closer to the first heating device 13 is referred to as one side, and the side closer to the false twisting device 15 is referred to as the other side. In this embodiment, cooling unit 31A and cooling unit 31B extend along a direction that is slightly inclined from the orthogonal direction.

[0091] like Figures 8-11 As shown, the cooling unit 31A includes a fixed wall panel 51 (the second wall component of the present invention), a movable wall panel 52 (the first wall component of the present invention), and a partition member 53. The fixed wall panel 51 corresponds to "one of the first wall component and the second wall component" of the present invention. The movable wall panel 52 corresponds to "the other of the first wall component and the second wall component" of the present invention. The fixed wall panel 51, the movable wall panel 52, and the partition member 53 are elongated components for forming two cooling spaces S (the first cooling space Sa and the second cooling space Sb). Figure 8 As shown, the fixed wall panel 51, the movable wall panel 52, and the partition member 53 extend relatively long in a direction orthogonal to the height direction and intersecting the length direction of the machine body. In the cooling unit 31A, the movable wall panel 52, the partition member 53, and the fixed wall panel 51 are arranged side by side in sequence from one side along the length direction of the machine body. That is, the movable wall panel 52 is located at the farthest side along the length direction of the machine body. The partition member 53 is located on the other side of the movable wall panel 52 along the length direction of the machine body and is adjacent to the movable wall panel 52. The fixed wall panel 51 is located on the other side of the partition member 53 along the length direction of the machine body and is adjacent to the partition member 53. In the cooling unit 31B, these components are arranged side by side in the reverse order along the length direction of the machine body (see reference). Figure 4 (Fixed wall panel 56, movable wall panel 57, and partition component 58).

[0092] Next, a more detailed description of the fixed wall panel 51 will be provided. For example... Figure 9 as well as Figure 10 As shown, the fixed wall panel 51 is a component with a generally C-shaped cross-section. That is, in Figure 9 as well as Figure 10 In the cross-section shown, the fixed wall panel 51 has a base end 61, a middle part 62, and a front end 63.

[0093] The base end 61 is an end disposed on one side of the fixed wall panel 51 in the height direction and extends along the length direction of the body. The base end 61 is fixed to the intake duct 32, for example, by a screw (not shown). More specifically, a wall portion 33 extending along the length direction of the body is formed at the end on the other side of the intake duct 32 in the height direction. The base end 61 is threaded to the wall portion 33. The intermediate portion 62 is a portion extending from the end of the base end 61 on one side of the body length direction to the other side in the height direction. A wall surface 64 (the second wall surface of the present invention) extending along the height direction is formed on one side of the intermediate portion 62 in the body length direction. The wall surface 64 is a surface for forming the second cooling space Sb in the cooling unit 31A. A plurality of contact bodies 65 (see reference) are provided on the wall surface 64 and are arranged separately from each other in the wire travel direction. Figure 10 as well as Figure 11 The contact body 65 is configured to actively contact the traveling thread Y (here, the second thread Yb) with the contact body 65. This prevents the second thread Yb from accidentally contacting portions of the wall surface 64 where the contact body 65 is not located. Furthermore, a plurality of through holes 66 extending along the length of the body are formed in the middle portion 62 (see reference). Figure 9 as well as Figure 10 The through hole 66 is a positioning hole through which the positioning pin 97b, described later, is inserted. The front end portion 63 is the portion that extends from the end on the other side in the height direction of the middle portion 62 to the other side in the length direction of the body.

[0094] Next, a more detailed explanation of the movable wall panel 52 will be provided. For example... Figure 9 as well as Figure 10 As shown, the movable wall panel 52 is a component with a generally C-shaped cross-section that is opposite to that of the fixed wall panel 51. That is, in Figure 9 as well as Figure 10 In the cross-section shown, the movable wall panel 52 has a base end 71, a middle part 72, and a front end 73.

[0095] The base end 71 is an end disposed on one side of the movable wall panel 52 in the height direction and extends along the length direction of the body. The middle part 72 is a portion that extends from the end of the base end 71 on the other side of the body length direction to the other side in the height direction. A wall surface 74 (the first wall surface of the present invention) extending along the height direction is formed on the other side of the middle part 72 in the body length direction. The wall surface 74 is a surface for forming the first cooling space Sa in the cooling unit 31A. A plurality of contact bodies 75 (see reference) are provided on the wall surface 74 and are arranged separately from each other in the wire travel direction. Figure 10 as well as Figure 11The contact body 75 is configured to actively contact the traveling first thread Ya. This prevents accidental contact between the first thread Ya and portions of the wall 74 where the contact body 75 is not located. Furthermore, a plurality of through holes 76 extending along the length of the body are formed in the middle portion 72 (see reference). Figure 9 as well as Figure 10 The through hole 76 is a positioning hole through which the positioning pin 97a, described later, is inserted. The front end portion 73 is a portion that extends from the end of the middle portion 72 on the other side in the height direction to one side in the length direction of the body.

[0096] Movable wall panel 52 is, for example, mounted on multiple spring units 54 (see reference). Figure 4 , Figure 5 , Figure 9 as well as Figure 10 Therefore, the movable wall panel 52 can move relative to the fixed wall panel 51 at least in the length direction of the machine body. The movable wall panel 52 can be in the operating position (see reference). Figure 4 and Figure 5 solid lines, and Figure 9 ) and unloading position ( Figure 4 and Figure 5 double-dotted lines, and Figure 10 The movable wall plate 52 moves between the two positions. The operating position is the position of the movable wall plate 52 when the false twisting machine 1 is running. The unloaded position is the position of the movable wall plate 52 when the separating component 53 is removed from the cooling unit 31A (details will be described later). The spring unit 54 is provided on one side of the movable wall plate 52 in the machine body length direction within the cooling unit 31A. In the cooling unit 31B, a spring unit 59 (see reference) with the same configuration as the spring unit 54 is provided. Figure 4 It is set on the other side of the body length direction of the movable wall panel 57.

[0097] Reference Figure 4 , Figure 9 as well as Figure 10 The detailed configuration of the spring unit 54 will be explained below. The spring unit 54 is a force-applying unit used to apply a force to the movable wall panel 52 towards the fixed wall panel 51. For example... Figure 4 As shown, the spring unit 54 includes, for example, a torsion spring 81, a fixing member 82, and a limiting pin 83. The torsion spring 81 has a helical portion (not shown), a fixing arm 84 disposed at one end of the helical portion, and a movable arm 85 disposed at the other end of the helical portion. The helical portion is fixed to the intake duct 32 by the fixing member 82. The movement of the fixing arm 84 is limited by the limiting pin 83 fixed to the intake duct 32. The movable arm 85 is mounted on, for example, the movable wall panel 52 and supports the movable wall panel 52.

[0098] Next, refer to Figures 9-11A more detailed description of the partition member 53 is provided. The partition member 53 is used to separate the first cooling space Sa and the second cooling space Sb along the length of the machine body. The partition member 53 is disposed between the fixed wall panel 51 and the movable wall panel 52 along the length of the machine body. The partition member 53 is configured to be detachable from the cooling unit 31A (details will be described later). The partition member 53 includes, for example, a first partition plate 86a, a second partition plate 86b, and a plurality of connecting members 87. The first partition plate 86a and the second partition plate 86b are connected by the plurality of connecting members 87. The first cooling space Sa is formed by the first partition plate 86a and the movable wall panel 52. The second cooling space Sb is formed by the second partition plate 86b and the fixed wall panel 51. The first cooling space Sa and the second cooling space Sb are arranged side-by-side along the length of the machine body. The first cooling space Sa and the second cooling space Sb are respectively connected to the intake space Ss.

[0099] The first partition plate 86a is a strip-shaped plate component that extends at least along an orthogonal direction (see reference). Figure 11 The first partition plate 86a is disposed at one end of the partition member 53 along the length of the body. The first partition plate 86a is fixed to the connecting member 87, for example, by screws not shown. The first partition plate 86a has a first partition portion 88a for forming the first cooling space Sa, and a first wire insertion guide portion 89a disposed on the other side of the first partition portion 88a in the height direction (see reference). Figure 9 as well as Figure 10 ).

[0100] A first partition surface 90a is formed in the first partition portion 88a. The first partition surface 90a is disposed on the other side of the wall surface 74 in the body length direction and is opposite to the wall surface 74 in the body length direction. A first cooling space Sa is formed by the first partition surface 90a and the wall surface 74. The first cooling space Sa is connected to the suction space Ss via a first suction slit 34a formed in the wall portion 33 of the suction duct 32. A plurality of contact bodies 91a are provided on the first partition surface 90a and are arranged separately from each other in the wire travel direction. When viewed from the height direction, the plurality of contact bodies 91a and the plurality of contact bodies 75 are arranged in a Z-shape (see reference). Figure 11 The contact body 91a is configured to actively contact the first thread Ya. This prevents accidental contact between the first thread Ya and portions of the first partition surface 90a where the contact body 91a is not located. Furthermore, a gasket 92a (see reference) is provided on one side of the first partition surface 90a in the body length direction to define a predetermined interval between the first partition surface 90a and the wall surface 74. Figure 10 The first partition 88a is provided with a plurality of through holes 93a and 94a that extend along the length of the fuselage (see reference). Figure 9 as well as Figure 10 Through hole 93a is used for insertion of the first wire guide 96a (described later). Through hole 94a is used for insertion of the positioning pin 97a (described later).

[0101] The first wire insertion guide portion 89a is disposed on the other side of the first partition portion 88a in the height direction. Compared with the first partition portion 88a, the first wire insertion guide portion 89a protrudes to the other side in the height direction (i.e., the working space Sw side) and to the other side in the length direction of the machine body (i.e., the second partition plate 86b side).

[0102] The second partition plate 86b is a strip-shaped plate component that extends at least along an orthogonal direction (see reference). Figure 11 The second partition plate 86b is disposed at the end of the partition member 53 on the other side of the body length direction. The second partition plate 86b is fixed to the connecting member 87, for example, by screws not shown. The second partition plate 86b has a second partition portion 88b for forming the second cooling space Sb, and a second wire insertion guide portion 89b disposed on the other side of the second partition portion 88b in the height direction (see reference). Figure 9 as well as Figure 10 ).

[0103] A second partition surface 90b is formed in the second partition portion 88b. The second partition surface 90b is disposed on one side of the wall surface 64 in the body length direction and is opposite to the wall surface 64 in the body length direction. A second cooling space Sb is formed by the second partition surface 90b and the wall surface 64. The second cooling space Sb and the suction space Ss are connected via a second suction slit 34b formed in the wall portion 33 of the suction duct 32. A plurality of contact bodies 91b are provided on the second partition surface 90b, which are arranged separately from each other in the wire travel direction. When viewed from the height direction, the plurality of contact bodies 91b and the plurality of contact bodies 65 are arranged in a Z-shape (see reference). Figure 11 The contact body 91b is configured to actively contact the second thread Yb. This prevents accidental contact between the second thread Yb and portions of the second separating surface 90b where the contact body 91b is not located. Furthermore, a gasket 92b identical to the gasket 92a is provided on one side of the second separating surface 90b along its length (see reference). Figure 10 The second partition 88b is provided with a plurality of through holes 93b and 94b that extend along the length of the fuselage (see reference). Figure 9 as well as Figure 10 Through hole 93b is used for insertion of the second wire guide 96b, described later. Through hole 94b is used for insertion of the locating pin 97b, described later.

[0104] The second wire insertion guide portion 89b is disposed on the opposite side of the second partition portion 88b in the height direction. Compared with the second partition portion 88b, the second wire insertion guide portion 89b protrudes to the opposite side in the height direction (i.e., the working space Sw side) and to one side in the length direction of the machine body (i.e., the first partition plate 86a side).

[0105] Multiple connecting parts 87 are configured to connect the first partition plate 86a and the second partition plate 86b. The multiple connecting parts 87 are arranged between the first partition plate 86a and the second partition plate 86b in the longitudinal direction of the fuselage. Figures 9-11 As shown, a first wire guide 96a, a second wire guide 96b, and positioning pins 97a and 97b are provided on each of the multiple connecting parts 87.

[0106] The first wire guide 96a is configured to guide the first wire Ya downstream in the wire travel direction. The first wire guide 96a is mounted, for example, on one side of the connecting member 87 along its length via a spring 98a. The first wire guide 96a is inserted through a through hole 93a in the first partition plate 86a and protrudes to one side along the length of the body. The first wire guide 96a is configured to move along the length of the body according to the extension and retraction of the spring 98a. Specifically, when the first wire guide 96a is pressed by the wall surface 74 of the movable wall plate 52, the spring 98a retracts. When the first wire guide 96a moves away from the wall surface 74, the spring 98a returns to its initial state.

[0107] The second wire guide 96b is configured to guide the second wire Yb downstream in the wire travel direction. The second wire guide 96b is mounted, for example, via a spring 98b to the other side of the connecting member 87 in the body length direction. The second wire guide 96b is inserted through a through hole 93b in the second partition plate 86b and protrudes to the other side in the body length direction. Similar to the first wire guide 96a, the second wire guide 96b is configured to be movable in the body length direction according to the extension and retraction of the spring 98b.

[0108] Positioning pin 97a is used for aligning the connecting member 87 with the movable wall panel 52. Positioning pin 97a is fixed, for example, to one side of the connecting member 87 along its length. Positioning pin 97a is inserted through a through hole 94a in the first partition plate 86a and protrudes to one side along its length. Positioning pin 97a is configured to be able to be inserted through a through hole 76 in the movable wall panel 52. Positioning pin 97b is used for aligning the connecting member 87 with the fixed wall panel 51. Positioning pin 97b is fixed, for example, to another side of the connecting member 87 along its length. Positioning pin 97b is inserted through a through hole 94b in the second partition plate 86b and protrudes to the other side along its length. Positioning pin 97b is configured to be able to be inserted through a through hole 66 in the fixed wall panel 51.

[0109] When the movable wall panel 52 is in the aforementioned operating position, the partition member 53, having the above configuration, is supported by the fixed wall panel 51 and the movable wall panel 52. More specifically, when the locating pin 97a is inserted through the through hole 76 and the locating pin 97b is inserted through the through hole 66, the partition member 53 is supported by both ends of the fixed wall panel 51 and the movable wall panel 52 (see reference). Figure 9 In other words, unlike the fixed wall panel 51, the partition member 53 is not fixed to the intake duct 32. Furthermore, when the movable wall panel 52 is in the aforementioned removed position, the partition member 53 can be removed from the cooling unit 31A (see reference). Figure 10 That is, the partition member 53 can be attached to and detached from the cooling unit 31A. In other words, the partition member 53 can move relative to the fixed wall panel 51 and the movable wall panel 52.

[0110] In the cooling unit 31A having the above configuration, when the false twisting machine 1 is operating, a first cooling space Sa and a second cooling space Sb, arranged side by side in the length direction of the machine body, are formed. In this embodiment, the interval between the first cooling space Sa and the second cooling space Sb in the length direction of the machine body (i.e., the interval between the first yarn Ya and the second yarn Yb in the length direction of the machine body) is constant. That is, in this embodiment, this interval does not change depending on the position in the direction in which the cooling unit 31A extends. Furthermore, this interval at the upstream end in the yarn travel direction of the cooling unit 31A is set to WC1 (refer to...). Figure 4 More precisely, WC1 is the distance along the length of the body between the center of the end of one side (the side of the first heating device 13) of the first cooling space Sa in the orthogonal direction and the center of the end of one side of the second cooling space Sb in the orthogonal direction. In this embodiment, the positions of the end of one side of the first cooling space Sa and the end of one side of the second cooling space Sb are approximately the same in the orthogonal direction. In this case, it is preferable that WC1 is at the aforementioned interval W1 (refer to...). Figure 4 The interval is approximately equal to or smaller than the interval W1. That is, preferably WC1 ≤ W1. Furthermore, this interval at the downstream end of the cooling unit 31A in the wire travel direction is set to WC2 (refer to...). Figure 5 More precisely, WC2 is the distance along the length of the body between the center of the end of the first cooling space Sa (the side of the false twist device 15) in the orthogonal direction and the center of the end of the second cooling space Sb in the orthogonal direction. In this embodiment, the positions of the ends of the first cooling space Sa and the second cooling space Sb are approximately the same in the orthogonal direction. In this case, it is preferable that WC2 is at the aforementioned interval W2 (refer to...). Figure 5) are approximately equal or larger than the interval W2. That is, it is preferably W2 ≤ WC2. Thus, the bending of the wire passage can be effectively suppressed. In the present embodiment, the following relationship holds.

[0111] W2 < WC2 = WC1 < W1

[0112] In addition, in such a configuration, when performing the wire hanging operation (described later) on the cooling unit 31A, the wire hanging operation can be performed while maintaining both the first wire Ya and the second wire Yb in a substantially straight line. That is, when performing the wire hanging operation on the cooling unit 31A, it is almost unnecessary to bend the first wire Ya and the second wire Yb. Therefore, the first wire Ya and the second wire Yb can be easily wire-hung on the cooling unit 31A simultaneously.

[0113] (Wire hanging operation)

[0114] In the present embodiment, when performing the wire hanging operation on the false twist machine 1, after the wire Y is hooked on the false twist device 15, the wire Y is hooked on the cooling device 14 and the first heating device 13. When hanging the wire on the cooling device 14 and the first heating device 13, for example, an operator uses an air injection device (not shown) to move the wire Y upward. Alternatively, it is also possible to use an air injection robot that can operate automatically without manual operation to move the wire Y upward. The reason is that in the false twist machine 1 of the present embodiment, the upstream end portion of the first heating device 13 in the wire traveling direction is at a relatively high position in the vertical direction, and it is difficult for the operator's hand to reach this upstream end portion. When hanging the wire by the above means, the first wire Ya is guided along the first wire insertion wire guiding portion 89a and enters the first cooling space Sa through the first inlet 95a. In addition, the second wire Yb is guided along the second wire insertion wire guiding portion 89b and enters the second cooling space Sb through the second inlet 95b. Also, during the wire hanging operation, the operator does not need to operate the cooling unit 31A (that is, it is not necessary to move the movable wall plate 52 and the partition member 53).

[0115] In addition, as described above, W2 < WC2 = WC1 < W1, so when performing the wire hanging operation on the cooling unit 31A, the wire hanging operation can be performed while maintaining both the first wire Ya and the second wire Yb in a substantially straight line. That is, when performing the wire hanging operation on the cooling unit 31A, it is almost unnecessary to bend the first wire Ya and the second wire Yb.

[0116] (Maintenance)

[0117] Furthermore, during maintenance such as cleaning the cooling unit 14, the operator moves the movable wall panel 52 from the operating position to the removed position and removes the partition member 53 from the cooling unit 31A. After cleaning the partition member 53, the operator installs the partition member 53 into the cooling unit 31A. More specifically, with the movable wall panel 52 in the removed position, the operator inserts the positioning pin 97b of the partition member 53 into the through hole 66. Then, the operator moves the movable wall panel 52 to the operating position, inserting the positioning pin 97a into the through hole 76. Thus, the partition member 53 is supported by the fixed wall panel 51 and both ends of the movable wall panel 52.

[0118] As described above, in the false twisting device 15 of the false twisting machine 1 of this embodiment, the first yarn Ya is sandwiched between the first annular belt 46a and the first contact surface 41a, and the second yarn Yb is sandwiched between the second annular belt 46b and the second contact surface 41b. This allows for reliable twisting of both the first yarn Ya and the second yarn Yb. Furthermore, since the first contact surface 41a and the second contact surface 41b are formed on the same circular plate 41, the spacing between the first yarn Ya and the second yarn Yb can be reduced in the false twisting device 15. Therefore, more yarns Y can be twisted in a smaller space. Moreover, in this false twisting device 15, the position where the first yarn Ya is false twisted can be made close to the position where the second yarn Yb is false twisted. Therefore, it is possible to suppress the large difference between the thread channels of the first thread Ya and the second thread Yb (in addition, due to its influence, the thread quality deviates between the first thread Ya and the second thread Yb).

[0119] Furthermore, in the cooling device 14 of the false twisting machine 1 of this embodiment, the first yarn Ya and the second yarn Yb can be reliably cooled by cooling air. Moreover, since the first cooling space Sa and the second cooling space Sb are formed within the same cooling unit 31A, the gap between the first yarn Ya and the second yarn Yb can be reduced within the cooling device 14. Therefore, more yarn Y can be cooled in a smaller space. Furthermore, as described above, since the gap between the first yarn Ya and the second yarn Yb can be reduced, the large difference between the yarn passages of the first yarn Ya and the second yarn Yb (and the resulting deviation in yarn quality) can be suppressed.

[0120] As described above, even when false twisting is applied to thicker yarn Y, it is possible to suppress the impairment of production efficiency and homogeneity, and ensure good yarn quality.

[0121] In addition, the first cooling space Sa and the second cooling space Sb are arranged side by side in the machine body length direction. Therefore, when the first thread Ya and the second thread Yb are conveyed from the cooling device 14 to the false twist device 15, the state where the first thread Ya and the second thread Yb are arranged side by side in the machine body length direction can be maintained. Thus, for example, compared with the case where the first cooling space Sa and the second cooling space Sb are arranged side by side in a direction different from the machine body length direction, the thread channels of the first thread Ya and the second thread Yb can be further suppressed from being different from each other. Therefore, the deviation of the thread quality between the first thread Ya and the second thread Yb can be effectively reduced.

[0122] In addition, WC2 is equal to WC1 (that is, WC2 is smaller). Therefore, when the first thread Ya and the second thread Yb are conveyed from the cooling device 14 to the false twist device 15, the bending of the first thread Ya and the second thread Yb can be suppressed. Thus, the reduction of the thread quality can be suppressed.

[0123] In addition, in the present embodiment, W2 < WC2 = WC1 < W1. Therefore, when performing the thread hanging operation on the cooling unit 31A, the thread hanging operation can be performed while maintaining both the first thread Ya and the second thread Yb in a substantially straight line state. That is, when performing the thread hanging operation on the cooling unit 31A, it is almost unnecessary to bend the first thread Ya and the second thread Yb. Thus, the first thread Ya and the second thread Yb can be easily hung on the cooling unit 31A simultaneously.

[0124] In addition, the first cooling space Sa and the second cooling space Sb are separated by the separating member 53. Therefore, compared with the configuration where the separating member 53 is not provided and the first cooling space Sa and the second cooling space Sb are not separated, it is possible to reliably prevent the first thread Ya and the second thread Yb from being wound around each other due to some reasons.

[0125] In addition, the first cooling space Sa and the second cooling space Sb are respectively connected to the suction space Ss extending along the machine body length direction (that is, connected in parallel). Therefore, cooling air can be supplied to the first cooling space Sa and the second cooling space Sb substantially uniformly through a simple structure.

[0126] In addition, the first cooling space Sa is formed by the wall surface 74 of the movable wall plate 52 and the first separating surface 90a of the first separating portion 88a, and the second cooling space Sb is formed by the wall surface 64 of the fixed wall plate 51 and the second separating surface 90b of the second separating portion 88b. Thus, the first cooling space Sa and the second cooling space Sb can be formed through a simple structure.

[0127] Furthermore, the first partition surface 90a is configured to face the wall surface 74 in the length direction of the body, and the second partition surface 90b is configured to face the wall surface 64 in the length direction of the body. This narrows the first inlet 95a and the second inlet 95b. Consequently, it is possible to prevent the first wire Ya from detaching from the first cooling space Sa, and to prevent the second wire Yb from detaching from the second cooling space Sb.

[0128] Furthermore, the cooling unit 31A includes a first guide wire 96a and a second guide wire 96b. Thus, the first yarn Ya is guided downstream in the yarn travel direction by the first guide wire 96a, and the second yarn Yb is guided downstream in the yarn travel direction by the second guide wire 96b. That is, the cooling unit 31A is not configured to actively contact the yarn Y with the partition surface and the wall surface. Therefore, when the yarn Y is twisted by the false twisting device 15, rolling along the wall surface or partition surface can be suppressed. Therefore, yarn Y can be prevented from falling out of the cooling space S.

[0129] Furthermore, the partition member 53 is supported by the fixed wall panel 51 and the movable wall panel 52. Therefore, even if the partition member 53 cannot be installed in the intake duct 32, the partition member 53 can still be configured normally. More specifically, the partition member 53 is supported at both ends. Therefore, the partition member 53 can be stably supported.

[0130] Furthermore, the partition member 53 can be detached from (i.e., moved relative to) the fixed wall panel 51 and the movable wall panel 52. This ensures a larger space for cleaning the fixed wall panel 51, the movable wall panel 52, and the partition member 53. Consequently, the efficiency of cleaning and other operations can be improved. Moreover, since the partition member 53 can be completely separated from the cooling unit 31A, the efficiency of cleaning and other operations can be significantly improved.

[0131] Furthermore, the position of the fixed wall panel 51 is fixed relative to the air intake duct 32, while the movable wall panel 52 and the partition member 53 can move relative to the fixed wall panel 51. This allows for the installation of a cooling unit 31B that is linearly symmetrical to the cooling unit 31A with the straight line L as its axis of symmetry. Even with such a cooling unit 31B, the two adjacent components (fixed wall panels 51 and 56) do not move. Therefore, when the components are moved during cleaning, interference between them can be avoided.

[0132] Furthermore, during the wire-hanging operation, the first wire Ya can be moved along the first wire insertion guide section 89a, and the second wire Yb can be moved along the second wire insertion guide section 89b. This improves the success rate of wire hanging.

[0133] Furthermore, as in this embodiment, when the upstream end of the first heating device 13 in the wire travel direction is at a higher position in the vertical direction, a device (not shown) for moving the wire Y upward is used to hook the wire onto the cooling device 14 and the first heating device 13. When performing this wire-hooking operation, it is particularly effective to improve the success rate of wire hooking by inserting the first wire into the guide portion 89a and the second wire into the guide portion 89b.

[0134] Next, variations of the above-described embodiments will be described. Elements having the same structure as those in the above-described embodiments will be labeled with the same symbols, and their descriptions will be omitted as appropriate.

[0135] (1) In the above embodiment, the partition member 53 is supported at both ends by the fixed wall plate 51 and the movable wall plate 52. However, it is not limited to this. The partition member 53 may also be configured to be cantilevered supported by one of the fixed wall plate 51 and the movable wall plate 52.

[0136] (2) In the embodiments described above, the partition member 53 is supported on at least one of the fixed wall panel 51 and the movable wall panel 52. However, it is not limited to this. For example, the partition member 53 may also be directly installed on the intake duct 32.

[0137] (3) In the embodiments described above, the partition member 53 can be detached from the cooling unit 31A. However, it is not limited to this. For example, the partition member 53 may also be configured to be movable in the longitudinal direction of the body while supported on at least one of the fixed wall panel 51 and the movable wall panel 52.

[0138] (4) In the embodiments described above, the movable wall panel 52 and the partition member 53 are movable relative to the fixed wall panel 51 and the suction pipe 32. However, this is not a limitation. For example, the partition member 53 may also be fixed to the suction pipe 32. In this case, instead of the fixed wall panel 51, a wall member (not shown) that is movable relative to the suction pipe 32 and the partition member 53 may be provided. The false twisting machine (not shown) thus configured is also equivalent to the "false twisting machine configured such that the partition member is movable relative to the first wall member and the second wall member" of the present invention.

[0139] (5) In the embodiments described above, the separating member 53 is configured to be movable relative to the first wall member and the second wall member of the present invention. However, this is not a limitation. The position of any of these members may also be fixed relative to the intake duct 32.

[0140] (6) In the embodiments described above, the cooling device 14 is a non-contact device having a first guide wire 96a and a second guide wire 96b. However, it is not limited to this. For example, as disclosed in Japanese Patent Application Publication No. 11-107084, the cooling device 14 may also be configured to actively contact the yarn Y with a wall surface (not shown). In addition, in this configuration, it is preferable to conduct certain studies to prevent the yarn Y from falling off the cooling device 14.

[0141] (7) In the embodiments described above, the first partition surface 90a is configured to face the wall surface 74 in the length direction of the body, and the second partition surface 90b is configured to face the wall surface 64 in the length direction of the body. That is, the first partition surface 90a is substantially parallel to the wall surface 74, and the second partition surface 90b is substantially parallel to the wall surface 64. However, this is not a limitation. For example, the first partition surface 90a and the wall surface 74 may also be configured such that the distance in the length direction of the body increases as they move towards the opposite side in the height direction. The same applies to the second partition surface 90b and the wall surface 64.

[0142] (8) In the embodiments described above, the cooling unit 31A has a fixed wall panel 51, a movable wall panel 52, and a partition member 53. However, it is not limited to this. For example, instead of the fixed wall panel 51, the movable wall panel 52, and the partition member 53, a component having the same function as these components may be installed in the air intake duct 32.

[0143] (9) In the embodiments described above, the first cooling space Sa and the second cooling space Sb are separated by the partition member 53, but this is not a limitation. For example, a plurality of pins (not shown) extending in the height direction may be arranged side by side between the first cooling space Sa and the second cooling space Sb in the wire travel direction. These pins may also be arranged separately from each other in the wire travel direction. This can restrict the movement of the first wire Ya and the second wire Yb in the length direction of the machine body, and prevent the first wire Ya and the second wire Yb from tangling together.

[0144] (10) In the embodiments described above, the first cooling space Sa and the second cooling space Sb are respectively connected to the intake space Ss extending along the length direction of the body (i.e., connected in parallel). However, this is not a limitation. For example, the first cooling space Sa and the second cooling space Sb may also be connected in series in the intake direction in which cooling air is drawn into the intake space Ss. That is, one of the first cooling space Sa and the second cooling space Sb may also be arranged upstream of the other in the intake direction.

[0145] (11) In the embodiments described above, the distance between the first cooling space Sa and the second cooling space Sb in the machine body length direction (that is, the distance between the first wire Ya and the second wire Yb in the machine body length direction) is constant. That is, in the cooling unit 31A, the first wire Ya and the second wire Yb are substantially parallel (further in other words, WC1 = WC2). However, it is not limited thereto. In the cooling unit 31A, the first wire Ya and the second wire Yb may not be substantially parallel. For example, the distance at the downstream end of the wire traveling direction in the cooling unit 31A may be narrower than the distance at the upstream end of the wire traveling direction (WC2 < WC1). That is, it may be WC2 ≤ WC1. Or, it may be WC1 < WC2.

[0146] In addition, in the orthogonal direction, the position of one end of the first cooling space Sa and the position of one end of the second cooling space Sb may not be substantially the same. In the orthogonal direction, the position of the other end of the first cooling space Sa and the position of the other end of the second cooling space Sb may not be substantially the same. In this case, the strict definitions of WC1 and WC2 are also the same as the above definitions.

[0147] (12) The relationship among W1, W2, WC1, and WC2 may also be other than W2 < WC2 = WC1 < W1. For example, as described above, in order to easily thread the first wire Ya and the second wire Yb into the cooling unit 31A at the same time, the wire guides G1, G2, and the cooling unit 31A may also be configured to satisfy any one of the following relationships. That is, it may be W2 ≤ WC2 ≤ WC1 ≤ W1. Or, it may be W1 ≤ WC1 ≤ WC2 ≤ W2. In this case, different from the embodiments described above, W2 may also be greater than W1.

[0148] Or, without considering whether the first wire Ya and the second wire Yb are threaded into the cooling unit 31A at the same time, the relationship among W1, W2, WC1, and WC2 is not limited to the above relationship.

[0149] (13) In the embodiments described above, the first cooling space Sa and the second cooling space Sb are arranged side by side in the machine body length direction, but it is not limited thereto. For example, like the cooling device (not shown) disclosed in Japanese Patent No. 4462751, the first cooling space (not shown) and the second cooling space (not shown) may also be arranged side by side in the height direction.

[0150] (14) In the embodiments described above, each of the plurality of cooling units 31 can cool two wires Y. However, it is not limited thereto. Hereinafter, refer to Figure 12 for description. For example, it may also be like Figure 12As shown, instead of cooling unit 31, a cooling unit 31M1 is provided, configured to cool three wires Y running side-by-side in the length direction of the machine body. The cooling unit 31M1 includes, for example, the aforementioned fixed wall panel 51, the aforementioned partition member 53, partition member 53A, and the aforementioned movable wall panel 52. The partition member 53A is disposed on the opposite side of the fixed wall panel 51 in the length direction of the machine body, separated by the partition member 53. Furthermore, in this modified example, the movable wall panel 52 is disposed on the opposite side of the fixed wall panel 51 in the length direction of the machine body, separated by the partition members 53 and 53A.

[0151] The separating member 53A is a member that extends at least along an orthogonal direction. The separating member 53A is, from and Figure 9 Cross section when viewed from the same direction (reference) Figure 12 The partition member 53A is roughly U-shaped. It includes a partition portion 88c, a bottom portion 99, a partition portion 88d, a wire insertion guide portion 89c, and a wire insertion guide portion 89d. The partition portion 88c extends along the height direction. The partition portion 88c has a partition surface 90c configured to face the first partition surface 90a along the length of the body. The aforementioned first cooling space Sa is formed between the first partition surface 90a and the partition surface 90c. A through hole 94c, approximately the same shape and size as the through holes 94a and 94b, is formed in the partition portion 88c. The bottom portion 99 is connected to the partition portion 88c and contacts the wall portion 33. The partition portion 88d is connected to the bottom portion 99 and extends along the height direction. The partition portion 88d has a partition surface 90d configured to face the wall surface 74 of the movable wall panel 52 along the length of the body. A cooling space Sd is formed between the wall surface 74 and the partition surface 90d for cooling a wire Yd that is different from the first wire Ya and the second wire Yb. A through hole 94d, having approximately the same shape and size as the through hole 94c, is formed in the partition portion 88d. The wire insertion guide portion 89c is connected to the partition portion 88c and extends in the height direction to the side opposite to the bottom 99. The wire insertion guide portion 89d is connected to the partition portion 88d and extends in the height direction to the side opposite to the bottom 99.

[0152] Furthermore, in the cooling unit 31M1, for example, an intake slit 34d connecting the intake space Ss and the cooling space Sd is formed in the wall portion 33. A connecting member 87A, having the same structure as the connecting member 87, is fixed to the movable wall panel 52. A gasket 92d, defining the gap between the wall surface 74 and the partition surface 90d, is provided between the wall surface 74 and the partition surface 90d in the length direction of the machine body. A wire guide 96d, having the same structure as the second wire guide 96b, is mounted on the connecting member 87A. A positioning pin 97d, having the same structure as the positioning pin 97b, is mounted on the connecting member 87A.

[0153] (15) As another variation, such as Figure 13 As shown, a cooling unit 31M2 can also be provided to cool four threads Y arranged side-by-side in the length direction of the body. Although detailed description is omitted, in the cooling unit 31M2, for example, two partition members 53 can be provided in the length direction of the body, separated by partition members 53A. Thus, in the cooling unit 31M2, a cooling space Se can be formed for cooling a thread Ye that is different from the first thread Ya, the second thread Yb, and the thread Yd. In this modified example, an air intake slit 34e connecting the air intake space Ss and the cooling space Se is formed in the wall portion 33. Furthermore, by applying this modified example and the modified example described above (13), each cooling unit (not shown) can also be configured to simultaneously cool five or more threads Y.
