Description

Technical Field

[0001] The present invention relates to a yarn-binding unit used in a yarn-binding apparatus for producing a mixed yarn by combining the first group of yarns and the second group of yarns after dividing multiple yarns spun from a spinning device into a first group of yarns and a second group of yarns and performing a stretching treatment on at least the first group of yarns. The invention also relates to a yarn-binding apparatus equipped with a yarn-binding unit. Background Technology

[0002] Fully drawn yarn (FDY) and partially oriented yarn (POY) have different shrinkage rates. It is known that bi-shrinkage yarn (BSY), which is made by combining two types of yarn with different shrinkage rates, has a good hand feel, and devices for manufacturing bi-shrinkage yarn have been proposed to date.

[0003] For example, in the apparatus of Patent Document 1, a portion of the multiple filaments spun from the spinning apparatus is heated and stretched by five heating rollers 31-35, which are configured as guide rollers with heating sections, thereby becoming fully drawn filaments. On the other hand, the remaining filaments spun from the spinning apparatus pass through a guide roller 36 instead of the heating rollers 31-33 arranged upstream in the filament travel direction among the five heating rollers 31-35, thereby becoming partially oriented filaments. Then, the fully drawn filaments and the partially oriented filaments are combined to generate a mixed filament.

[0006] Patent Document 1: Japanese Patent Application Publication No. 2021-102835 Summary of the Invention

[0007] In manufacturing blended yarn, the following yarn-coating operation is performed: Multiple yarns spun from the spinning device are drawn in through a suction gun, and simultaneously divided into a first group and a second group. The second group of yarns is then wound onto guide rollers, and the first group of yarns is wound onto multiple guide rollers equipped with heating elements. In this yarn-coating operation, when dividing the multiple yarns into the first and second groups, the operator first holds the suction gun in one hand and a yarn-separating tool that hooks the yarns onto the front end with the other hand. Then, the multiple spun yarns are drawn in through the suction gun held in one hand, and the yarn-separating tool held in the other hand is used to divide the spun yarns into the first and second groups. Next, the operator operates the position of the suction gun while winding the second group of yarns onto the guide rollers and sequentially winding the first group of yarns onto the multiple guide rollers. At this point, the operator needs to prevent the second group of threads from being wound up relative to the multiple guide rollers in the same way as the first group of threads, and maintain the state of separating the thread channels of the first group of threads from those of the second group of threads. The operator then winds up the first group of threads relative to the multiple guide rollers in sequence to perform the thread winding operation.

[0008] During the aforementioned yarn loading operation, the operator needs to operate a heavy suction gun with one hand and a yarn separating tool with the other, maintaining the yarn channels of the first and second groups of yarns separate while sequentially winding the first group of yarns relative to multiple guide rollers. Therefore, simultaneously maintaining the separation of the first and second group of yarn channels while operating a heavy suction gun presents the following problems: it places a heavy burden on the operator, making the yarn loading operation difficult and requiring a significant amount of time. Furthermore, if the operation time increases, the amount of yarn sucked into the suction gun during this period increases, leading to increased yarn retraction.

[0009] In view of the above, the present invention aims to provide a wire-hanging unit and a mixed-filament manufacturing apparatus having the wire-hanging unit: which can easily perform a wire-hanging operation in which the first group of filaments is sequentially wound relative to multiple guide rollers while operating the suction gun with both hands, can significantly shorten the operation time required for the wire-hanging operation, and can significantly reduce the amount of filaments sucked in by the suction gun, thereby greatly reducing the amount of filaments generated.

[0010] (1) In order to solve the above-mentioned problems, a yarn-hanging unit according to a certain aspect of the present invention is used in a yarn-making apparatus for producing mixed yarn by combining a first group of yarns and a second group of yarns, when the second group of yarns is wound on a guide roller and the first group of yarns is wound on a plurality of guide rollers. The mixed yarn-making apparatus includes: a plurality of the guide rollers having a heating source, which at least winds the first group of yarns, which are a portion of the yarns spun from a plurality of yarns from a spinning device, and heats and stretches the first group of yarns at least; an insulated box having a box body for housing the plurality of guide rollers and a door for opening and closing the box body; and the guide rollers for guiding the second group of yarns, which are a portion of the yarns other than the first group of yarns, from the plurality of yarns. The aforementioned wire-hanging unit is characterized by comprising: a mounting portion that can be detachably mounted to and detachably from the aforementioned housing body; and a wire-hanging portion that, when the mounting portion is mounted to the aforementioned housing body, extends along the edge of the aforementioned housing body closer to the guide rollers than the plurality of guide rollers, and hooks the second set of wires; the wire-hanging portion is configured to, when the mounting portion is mounted to the aforementioned housing body, extend along the edge of the aforementioned housing body at a position protruding from the end faces of the plurality of guide rollers in the axial direction of the guide rollers.

[0011] According to the configuration of the present invention, when performing a yarn-hanging operation in a blended yarn manufacturing apparatus during the manufacturing of blended yarn, firstly, a yarn-hanging unit is installed at the edge of the main body of the insulated box, closer to the guide rollers than the multiple guide rollers. At this time, the yarn-hanging portion of the yarn-hanging unit is configured to extend along the edge of the main body at a position protruding from the end faces of the multiple guide rollers in the axial direction. Then, in this state, the yarn-hanging operation is performed. When the yarn-hanging operation begins, the operator draws in multiple yarns spun from the spinning device using a suction gun, while dividing the multiple yarns into a first group and a second group. The separated second group of yarns is wound onto the guide rollers positioned closer to the yarn-hanging unit than the multiple guide rollers. Then, the operator holds the suction gun that draws in multiple yarns with both hands, and operates the position of the suction gun to sequentially wind the first group of yarns relative to the multiple guide rollers. At this time, the second set of yarn, wound on the guide rollers and sucked into the suction gun, is hooked in the yarn channel from the guide rollers to the suction port of the suction gun. This hook is located at a position protruding outwards from the multiple guide rollers towards the main body of the box, and at a position protruding axially from the end face of the guide rollers along the edge of the main body. Therefore, when the operator operates the suction gun with both hands to sequentially wind the first set of yarn relative to the multiple guide rollers, the second set of yarn remains hooked at the hook of the hook unit. Thus, during the operation of winding the first set of yarn onto the multiple guide rollers, the yarn channel of the second set of yarn is maintained in the following state: a portion of the yarn channel of the second set of yarn located between the guide rollers and the suction gun winds around to a position protruding outwards from the multiple guide rollers towards the main body of the box, and at a position protruding axially from the end face of the guide rollers. Therefore, it is possible to prevent the second group of threads from being wound onto the guide rollers through the same thread path as the first group of threads. Consequently, the operator can easily perform the thread-hanging operation—sequentially winding the first group of threads relative to multiple guide rollers—while maintaining a state where the thread paths of the first and second groups of threads are separated, using both hands to operate the weighted suction gun. Furthermore, because the thread-hanging operation can be performed easily, the operation time required for thread-hanging can be significantly reduced. Moreover, by significantly reducing the operation time for thread-hanging, the amount of thread sucked into the suction gun during the operation can be reduced, significantly decreasing the amount of spun thread generated.

[0012] Therefore, according to the configuration of the present invention, a wire-hanging unit can be provided that allows for easy wire-hanging operations of sequentially winding the first group of wires relative to multiple guide rollers while operating the suction gun with both hands, significantly reducing the operation time required for wire-hanging operations, and simultaneously reducing the amount of wire sucked in by the suction gun, thereby significantly reducing the amount of wire re-spinning.

[0013] (2) Alternatively, the wire hanging part may have a rod-shaped portion that extends in a straight line along the edge of the box body that is closer to the guide roller than the plurality of wire guide rollers when the mounting part is mounted on the box body.

[0014] According to this configuration, a wire-hanging unit can be easily constructed by having a wire-hanging part with a rod-shaped portion extending in a straight line and a mounting part for the main body of the box. That is, a wire-hanging unit can be easily constructed with a simple configuration, in which the wire-hanging operation of winding the first group of wires onto multiple guide rollers can be easily performed by operating the suction gun with both hands while keeping the wire channels of the first group and the second group of wires separated.

[0015] (3) Alternatively, the wire hanging part may have a portion that extends in a flat shape along the edge of the box body that is closer to the guide roller than the plurality of guide rollers when the mounting part is mounted on the box body.

[0016] According to this configuration, a wire-hanging unit can be easily constructed with a simple structure having a wire-hanging part having a flat, extended portion and a mounting part to the main body of the box. That is, a wire-hanging unit can be easily constructed with a simple structure, in which the wire-hanging operation of winding the first group of wires onto multiple guide rollers can be easily performed by operating the suction gun with both hands while maintaining the wire channels of the first group and the second group of wires separated.

[0017] Furthermore, the wire-hanging unit of the present invention does not necessarily have all the configurations described in (1) to (3) above. For example, in the invention of the wire-hanging unit described in (1) above, the configurations described in (2) to (3) above are not necessary. In addition, within the scope of integration, the configuration described in (1) above and a portion of the configurations described in (2) to (3) above can be arbitrarily combined to form the wire-hanging unit of the present invention. For example, the configuration described in (1) above and the configuration described in (2) above can be combined to form the wire-hanging unit of the present invention, and the configuration described in (1) above and the configuration described in (3) above can also be combined to form the wire-hanging unit of the present invention.

[0018] (4) In order to solve the above-mentioned problems, a yarn-hanging unit according to a certain aspect of the present invention is used in a yarn-making apparatus for producing mixed yarn by combining a first group of yarns and a second group of yarns, when the second group of yarns is wound on a guide roller and the first group of yarns is wound on a plurality of guide rollers. The mixed yarn-making apparatus includes: a plurality of the guide rollers, each having a heating source, for at least winding the first group of yarns which are a portion of the yarns spun from a spinning device, and for at least heating and stretching the first group of yarns; an insulated box having a box body for housing the plurality of guide rollers and a door for opening and closing the box body; and the guide rollers for guiding the second group of yarns which are a portion of the yarns other than the first group of yarns. The aforementioned wire-hanging unit is characterized by comprising: a mounting portion that can be detachably mounted to and detachably from the aforementioned housing body; and a wire-hanging portion that, when the mounting portion is mounted to the aforementioned housing body, extends along the edge of the side wall of the aforementioned housing body, which is away from the plurality of aforementioned wire guide rollers and on which the aforementioned guide rollers are arranged, to hook the aforementioned second set of wires; the wire-hanging portion is configured to, when the mounting portion is mounted to the aforementioned housing body, extend along the edge of the side wall of the aforementioned housing body at a position that protrudes from the end faces of the plurality of aforementioned wire guide rollers in the axial direction of the aforementioned wire guide rollers.

[0019] According to the configuration of the present invention, when performing a yarn hanging operation in a blended yarn manufacturing apparatus during the manufacturing of blended yarn, firstly, a yarn hanging unit is installed on the edge of the side wall of the main body of the insulated box, which is located away from the multiple guide rollers and on which guide rollers are arranged. At this time, the yarn hanging portion of the yarn hanging unit is configured to extend along the edge of the side wall of the main body at a position protruding from the end faces of the multiple guide rollers in the axial direction. Then, in this state, the yarn hanging operation is performed. When the yarn hanging operation begins, the operator uses a suction gun to draw in multiple yarns spun from the spinning device, while dividing the multiple yarns into a first group and a second group. The separated second group of yarns is wound onto the guide rollers located on the side wall of the main body of the box, which is located away from the multiple guide rollers and on which the yarn hanging unit is installed. Then, the operator holds the suction gun that draws in multiple yarns with both hands, and operates the position of the suction gun to sequentially wind the first group of yarns relative to the multiple guide rollers. At this time, the second set of yarn, wound on the guide rollers and sucked into the suction gun, is hooked in the yarn channel from the guide rollers to the suction inlet of the suction gun. This hook is located at a position protruding outwards from the multiple guide rollers towards the main body of the box, and at a position protruding axially from the end face of the guide rollers along the edge of the side wall of the main body. Therefore, when the operator uses both hands to hold the suction gun and performs the operation of sequentially winding the first set of yarn relative to the multiple guide rollers, the second set of yarn remains hooked to the hook of the hook unit. Thus, during the operation of winding the first set of yarn onto the multiple guide rollers, the yarn channel of the second set of yarn is maintained in the following state: a portion of the yarn channel of the second set of yarn located between the guide rollers and the suction gun winds around to a position protruding outwards from the multiple guide rollers towards the main body of the box, and at a position protruding axially from the end face of the guide rollers. Therefore, it is possible to prevent the second group of threads from being wound onto the guide rollers through the same thread path as the first group of threads. Consequently, the operator can easily perform the thread-hanging operation—sequentially winding the first group of threads relative to multiple guide rollers—while maintaining a state where the thread paths of the first and second groups of threads are separated, using both hands to operate the weighted suction gun. Furthermore, because the thread-hanging operation can be performed easily, the operation time required for thread-hanging can be significantly reduced. Moreover, by significantly reducing the operation time for thread-hanging, the amount of thread sucked into the suction gun during the operation can be reduced, significantly decreasing the amount of spun thread generated.

[0020] Therefore, according to the configuration of the present invention, a wire-hanging unit is provided, which can easily perform the wire-hanging operation of sequentially winding the first group of wires relative to multiple guide rollers while operating the suction gun with both hands, which can significantly shorten the operation time required for the wire-hanging operation, and can significantly reduce the amount of wire sucked in by the suction gun and thus significantly reduce the generated wire retraction.

[0021] (5) To solve the above-mentioned problems, a mixed yarn manufacturing apparatus according to one aspect of the present invention is characterized by comprising: a plurality of guide rollers having a heating source, at least winding a first group of yarns separated from a plurality of yarns spun from a spinning device, and at least heating and stretching the first group of yarns; an insulation box having a box body for housing the plurality of guide rollers and a door for opening and closing the box body; guide rollers for guiding a second group of yarns separated from the plurality of yarns as yarns other than the first group of yarns; and a yarn-coating device for combining the first group of yarns with... The second group of yarns is plied together to generate a mixed yarn; and a yarn-hanging unit is used when the second group of yarns is wound onto the guide rollers and the first group of yarns is wound onto the plurality of guide rollers. The yarn-hanging unit has: a mounting part, which is mounted on the main body of the box; and a yarn-hanging part, which is provided to extend along the edge of the main body of the box closer to the guide rollers than the plurality of guide rollers, and hooks the second group of yarns. The yarn-hanging part is provided to extend along the edge of the main body of the box at a position that protrudes from the end face of the plurality of guide rollers in the axial direction of the guide rollers.

[0022] According to the configuration of the present invention, when performing a yarn-hanging operation during the manufacturing of blended yarns, a yarn-hanging unit is installed at the edge of the main body of the insulation box, closer to the guide rollers than the multiple guide rollers. Furthermore, the yarn-hanging portion of the yarn-hanging unit is configured to extend along the edge of the main body of the box at a position protruding from the end faces of the multiple guide rollers in the axial direction. In this state, the yarn-hanging operation is performed. When the yarn-hanging operation begins, the operator draws in multiple yarns spun from the spinning device using a suction gun, and divides the multiple yarns into a first group and a second group. The separated second group of yarns is wound onto the guide rollers positioned closer to the yarn-hanging unit than the multiple guide rollers. Then, the operator holds the suction gun that draws in the multiple yarns with both hands, and manipulates the position of the suction gun to sequentially wind the first group of yarns relative to the multiple guide rollers. At this time, the second set of yarn, wound on the guide rollers and sucked into the suction gun, is hooked in the yarn channel from the guide rollers to the suction port of the suction gun. This hook is located at a position protruding outwards from the multiple guide rollers towards the main body of the box, and at a position protruding axially from the end face of the guide rollers. It extends along the edge of the main body of the box. Therefore, when the operator uses both hands to hold the suction gun and sequentially winds the first set of yarn relative to the multiple guide rollers, the second set of yarn remains hooked at the hook of the hook unit. Thus, during the winding of the first set of yarn onto the multiple guide rollers, the yarn channel of the second set of yarn is maintained in the following state: between the guide rollers and the suction gun, it winds to a position protruding outwards from the multiple guide rollers towards the main body of the box, and at a position protruding axially from the end face of the guide rollers. Therefore, it is possible to prevent the second set of yarn from being wound onto the guide rollers with the same yarn channel as the first set of yarn. Therefore, the operator can easily perform the wire-hanging operation—sequentially winding the first set of threads relative to multiple guide rollers—while maintaining the separation between the thread channels of the first and second sets of threads using both hands. Furthermore, the ease of wire-hanging significantly reduces the operation time. This reduction in operation time also decreases the amount of thread drawn into the suction gun during the operation, drastically reducing the amount of spun yarn.

[0023] Therefore, according to the configuration of the present invention, a mixed yarn manufacturing apparatus is provided that can easily perform the yarn hanging operation of sequentially winding the first group of yarns relative to multiple guide rollers while operating the suction gun with both hands, which can significantly shorten the operation time required for the yarn hanging operation and significantly reduce the amount of yarn sucked in by the suction gun, thereby greatly reducing the amount of yarn waste generated.

[0024] (6) To solve the above-mentioned problems, a mixed yarn manufacturing apparatus according to one aspect of the present invention is characterized by comprising: a plurality of guide rollers having a heating source, at least winding a first group of yarns separated from a plurality of yarns spun from a spinning device, and at least heating and stretching the first group of yarns; an insulation box having a box body for housing the plurality of guide rollers and a door for opening and closing the box body; guide rollers for guiding a second group of yarns separated from the plurality of yarns as yarns other than the first group of yarns; and a yarn-coating device for combining the first group of yarns with the second group of yarns. The yarns are plied together to generate mixed yarns; and a yarn-hanging unit is used when the second group of yarns is wound onto the guide rollers and the first group of yarns is wound onto the plurality of guide rollers. The yarn-hanging unit has: a mounting part, which is mounted on the main body of the box; and a yarn-hanging part, which is provided to extend along the edge of the side wall of the main body of the box away from the plurality of guide rollers and on which the guide rollers are arranged, and hooks the second group of yarns. The yarn-hanging part is provided to extend along the edge of the side wall of the main body of the box at a position that protrudes from the end face of the plurality of guide rollers in the axial direction of the guide rollers.

[0025] According to the configuration of the present invention, when performing a yarn hanging operation during the manufacturing of blended yarns, a yarn hanging unit is installed on the edge of the side wall of the main body of the insulated box, away from the multiple guide rollers and on which guide rollers are arranged. Furthermore, the yarn hanging portion of the yarn hanging unit is configured to extend along the edge of the side wall of the main body at a position protruding from the end faces of the multiple guide rollers in the axial direction. In this state, the yarn hanging operation is performed. When the yarn hanging operation begins, the operator draws in multiple yarns spun from the spinning device using a suction gun, and divides the multiple yarns into a first group and a second group. The separated second group of yarns is wound onto the guide rollers arranged on the side wall of the main body of the box, away from the multiple guide rollers and on which the yarn hanging unit is installed. Then, the operator holds the suction gun that draws in multiple yarns with both hands and operates the position of the suction gun to sequentially wind the first group of yarns relative to the multiple guide rollers. At this time, the second set of yarn, wound on the guide rollers and sucked into the suction gun, is hooked in the yarn channel from the guide rollers to the suction port of the suction gun. This hook is located at a position protruding outwards from the multiple guide rollers towards the main body of the box, and at a position protruding axially from the end face of the guide rollers beyond the guide rollers. Therefore, when the operator operates the suction gun with both hands to sequentially wind the first set of yarn relative to the multiple guide rollers, the second set of yarn remains hooked at the hook of the hooking unit. Thus, during the operation of hooking the first set of yarn onto the multiple guide rollers, the yarn channel of the second set of yarn is maintained in the following state: a portion of the yarn channel of the second set of yarn located between the guide rollers and the suction gun winds around to a position protruding outwards from the multiple guide rollers towards the main body of the box, and at a position protruding axially from the end face of the guide rollers beyond the guide rollers. Therefore, it is possible to prevent the second group of threads from being wound onto the guide rollers through the same thread path as the first group of threads. Consequently, the operator can easily perform the thread-hanging operation—sequentially winding the first group of threads relative to multiple guide rollers—while maintaining a state where the thread paths of the first and second groups of threads are separated, by operating the weighted suction gun with both hands. Furthermore, because the thread-hanging operation can be performed easily, the operation time required for the thread-hanging operation can be significantly reduced. Moreover, by significantly reducing the operation time for the thread-hanging operation, the amount of thread sucked into the suction gun during the operation can be reduced, significantly decreasing the amount of spun yarn generated.

[0026] Therefore, according to the configuration of the present invention, a mixed yarn manufacturing apparatus is provided that can easily perform the yarn hanging operation of sequentially winding the first group of yarns relative to multiple guide rollers while operating the suction gun with both hands, which can significantly shorten the operation time required for the yarn hanging operation and significantly reduce the amount of yarn sucked in by the suction gun, thereby greatly reducing the amount of yarn waste generated.

[0027] Effects of the invention: According to the present invention, a wire hanging unit and a mixed wire manufacturing apparatus having the wire hanging unit are provided, which can easily perform the wire hanging operation of sequentially winding the first group of wires relative to multiple guide rollers while operating the suction gun with both hands, which can significantly shorten the operation time required for the wire hanging operation, and can significantly reduce the amount of wire sucked in by the suction gun and thus significantly reduce the amount of wire re-spinning.

Figure 1 The hybrid filament manufacturing apparatus 1 and shown Figure 4 The device shown is the wire-hanging unit 5. Furthermore, for ease of explanation, the vertical, horizontal, and lateral directions of the mixed-fiber manufacturing device 1 are as follows: Figure 1 and even Figure 3 Defined as shown.

[0066] [Overall Structure of the Hybrid Fiber Manufacturing Apparatus]

[0067] The blended yarn manufacturing apparatus 1 divides multiple synthetic fiber filaments Y, which are formed by the solidification of molten resin continuously spun from the spinning apparatus 2, into a first group of filaments Y1 and a second group of filaments Y2. The first group of filaments Y1 is then stretched to create filaments with different shrinkage rates. Specifically, the blended yarn manufacturing apparatus 1 stretches the first group of filaments Y1 to form a fully drawn filament (FDY), and does not stretch the second group of filaments Y2 to form a partially oriented filament (POY). This results in filaments with different shrinkage rates. Subsequently, the blended yarn manufacturing apparatus 1 combines the fully drawn filament (FDY), i.e., the first group of filaments Y1, and the partially oriented filament (POY), i.e., the second group of filaments Y2, to generate a blended yarn Y3 (BSY). It is known that a blended yarn Y3, composed of two types of yarns Y1 and Y2 with different shrinkage rates, has a good hand feel. Furthermore, in this specification, unless otherwise specified, the type of yarn is abbreviated as yarn Y.

[0068] The mixed yarn manufacturing apparatus 1 is configured to include a spinning and stretching device 3, a winding device 4, a fiber guide 11, a feeding roller 12-15, and a yarn combining device 16.

[0069] The fiber separator 11, for example, is a comb-shaped fiber separator, positioned below the spinning device 2. All the multiple filaments Y spun from the spinning device 2 are divided in the fiber separator 11 into two groups: a first group of filaments Y1 and a second group of filaments Y2, each in equal parts. For example, if there are 16 multiple filaments Y spun from the spinning device 2, they are divided into 8 first group filaments Y1 and 8 second group filaments Y2, ultimately producing 8 mixed filaments Y3.

[0070] Feed rollers 12-15 are driven to rotate by an electric motor (not shown). Feed rollers 12 and 13 have a rotating shaft extending in the front-to-back direction. Feed roller 12 is positioned between the fiber guide 11 and the insulation box 30 (described later) in the spinning and stretching device 3 in the direction of yarn travel of the first group of yarns Y1. Feed rollers 13-15 are positioned between the spinning and stretching device 3 and the winding device 4 in the direction of yarn travel of yarn Y.

[0071] The first set of yarns Y1 is fed into the heat preservation box 30 of the spinning and stretching device 3 via the fiber guide 11 and the feeding roller 12. On the other hand, the second set of yarns Y2 is fed to the feeding roller 13 via the guide rollers 36 and 37 in the spinning and stretching device 3 after passing through the fiber guide 11.

[0072] The first group of yarns Y1, drawn from the heat preservation box 30 of the spinning and stretching device 3, and the second group of yarns Y2, fed from the guide roller 37 of the spinning and stretching device 3, are conveyed to the doubling device 16 via the feeding rollers 13 and 14. The doubling device 16 is arranged between the feeding rollers 14 and 15 in the yarn travel direction of the yarn Y. The doubling device 16 is a device for doubling the first group of yarns Y1 and the second group of yarns Y2 to generate a mixed yarn Y3. The doubling device 16 is configured as a winding device that sprays compressed air and uses the compressed air to doubling the first group of yarns Y1 and the second group of yarns Y2. The mixed yarn Y3 generated by doubling the first group of yarns Y1 and the second group of yarns Y2 by the doubling device 16 is conveyed to the winding device 4 via the feeding roller 15.

[0073] The winding device 4 includes multiple pivot guides 41, multiple traverse devices 42, contact rollers 43, two bobbin supports 44, and a cradle 45. Furthermore, the multiple pivot guides 41 and the multiple traverse devices 42 are arranged in a manner corresponding to each other in the front-to-back direction. Figure 1 The diagram is superimposed in the front-to-back direction. Multiple mixed yarns Y3, fed to the winding device 4, are moved laterally in the front-to-back direction around multiple pivot guides 41 via corresponding traverse devices 42. Contact rollers 43 are configured to contact the surfaces of multiple packages P and apply a predetermined contact pressure, adjusting the shape of the packages P. Furthermore, the multiple packages P are arranged in the front-to-back direction... Figure 1The diagram is shown overlapping in the front-to-back direction. A bobbin support 44 extends along the front-to-back direction and is configured to mount multiple bobbins B in a front-to-back arrangement. The bobbin support 44 is driven to rotate by an electric motor (not shown). A cradle 45 is configured to cantilever and support the two bobbin supports 44, and is also driven to rotate by an electric motor (not shown). In the winding device 4, the cradle 45 is driven to rotate, thereby switching the position of the two bobbin supports 44 between the upper winding position and the lower standby position.

[0074] The winding device 4 forms multiple packages P by rotating the bobbin support 44 located at the upper winding position and winding multiple mixed yarns Y3 onto multiple bobbins B. When multiple packages P are completed, the cradle 45 is rotated to switch the positions of the two bobbin supports 44. Then, multiple mixed yarns Y3 are wound onto the multiple bobbins B mounted on the bobbin supports 44 that have been moved to the new winding position.

[0075] [Spinning and stretching device]

[0076] Reference Figure 1 and even Figure 3 The spinning and stretching device 3 is configured to include a heat preservation box 30, multiple (five in this embodiment) guide rollers 31-35 with heating sources, and multiple (two in this embodiment) guide rollers 36 and 37. Furthermore, in Figure 2 In the diagram, the first group of silk thread Y1 is represented by a single-dotted line, the second group of silk thread Y2 is represented by a double-dotted line, and the mixed silk thread Y3 is represented by a solid line.

[0077] Multiple guide rollers 31-35 are housed inside the insulation box 30. Furthermore, the multiple guide rollers 31-35 are configured to wind up the first group of yarn Y1, which is a portion of the yarn Y1 spun from the multiple yarns Y spun from the spinning device 2, and to heat and stretch the first group of yarn Y1.

[0078] Guide rollers 31-35 have a rotating shaft extending in the front-to-back direction, configured to be operated by an electric motor (not shown). Figure 2 The rollers are driven to rotate in the directions indicated by the arrows. Furthermore, the guide rollers 31-35 have built-in heaters (heating sources, omitted from the illustration), configured to heat the yarn Y wound around the circumference of the guide rollers 31-35. All guide rollers 31-35 have approximately the same outer diameter.

[0079] Of the five guide rollers 31-35, the three upstream guide rollers 31-33 in the yarn travel direction are configured as preheating rollers for preheating the first group of yarn Y1 before stretching. The surface temperature of the guide rollers 31-33 as preheating rollers is set to a temperature above the glass transition point of yarn Y (e.g., around 80°C). On the other hand, the two guide rollers 34 and 35 downstream of the five guide rollers 31-35 in the yarn travel direction are configured as heat setting rollers for heat setting (heat treatment) of the first group of yarn Y1. The surface temperature of the guide rollers 34 and 35 as heat setting rollers is set to a temperature higher than the surface temperature of the guide rollers 31-33 as preheating rollers (e.g., around 130-140°C).

[0080] Furthermore, the rotational speed (i.e., the feeding speed) of the guide rollers 34 and 35 on the downstream side of the yarn travel direction is set to be faster than the rotational speed (i.e., the feeding speed) of the guide rollers 31 to 33 on the upstream side of the yarn travel direction. As a result, the first set of yarn Y1 reaches the guide roller 34 via the guide rollers 31 to 33 and is stretched between the guide rollers 33 and 34.

[0081] The first guide roller 31 (i.e., the upstream side in the direction of yarn travel) of the three guide rollers 31-33, which serve as preheating rollers, is positioned lower than the remaining two guide rollers 32 and 33. The second guide roller 32 and the third guide roller 33 in the direction of yarn travel are arranged adjacent to each other in the left-right direction. The axis of the second guide roller 32 is located to the right of the axis of the upstream guide roller 31 in the direction of yarn travel. Furthermore, the axis of the third guide roller 33 is located to the left of the axis of the upstream guide roller 31 in the direction of yarn travel.

[0082] The fourth and fifth guide rollers in the yarn travel direction, namely guide rollers 34 and 35, are arranged adjacent to each other in the left-right direction above guide rollers 31 to 33. The fourth guide roller 34 in the yarn travel direction is arranged adjacent to the upper side of the second guide roller 32 in the yarn travel direction. The fifth guide roller 35 in the yarn travel direction is arranged above the third guide roller 33 in the yarn travel direction. In addition, the fifth guide roller 35 in the yarn travel direction is offset upwards compared to the fourth guide roller 34 in the yarn travel direction. More specifically, the axis of the fifth guide roller 35 in the yarn travel direction is located above the axis of the fourth guide roller 34 in the yarn travel direction.

[0083] As described above, the five guide rollers 31 to 35 are arranged in a compact and dense configuration in both the left-right and up-down directions.

[0084] like Figure 3 As shown, the insulation box 30 has a main body 38 with a front opening that houses multiple guide rollers 31-35, and a door 39 for opening and closing the main body 38. The door 39 is closed when the spinning and stretching device 3 is in operation. In the insulation box 30, the door 39 is a swing door. Furthermore, the door 39 is rotatably mounted to the left side wall 38a of the main body 38 via a hinge (not shown).

[0085] In addition, such as Figure 2 as well as Figure 3 As shown, an inlet 30a and an outlet 30b are formed on the right side wall 38b of the box body 38. The inlet 30a is formed at the lower end of the right side wall 38b of the box body 38 and is configured as an opening for introducing the first set of wires Y1 into the interior of the insulation box 30. The outlet 30b is formed at the upper end of the right side wall 38b of the box body 38 and is configured as an opening for exporting the heated and stretched first set of wires Y1 to the outside. In addition, a locking groove 38c is provided on the right side wall 38b of the box body 38, which engages with a locking claw (not shown) provided on the side of the door 39 when the door 39 is closed. Multiple locking grooves 38c are provided, and in this embodiment, two are provided. The two locking grooves 38c are arranged vertically along the edge of the right side wall 38b of the box body 38. In addition, the locking groove 38c is configured to open at the edge of the side wall 38b of the box body 38. Furthermore, a stepped portion is provided on the inner side of the locking groove 38c to engage with the locking claw on the door 39 side. When the door 39 closes the main body 38, for example, the locking claw of the door 39 is inserted into the locking groove 38c, and by driving the locking claw in this state, the locking claw engages with the stepped portion of the locking groove 38c.

[0086] Guide rollers 36 and 37 are configured to guide a second group of yarns Y2, which is derived from the first group of yarns Y1, from the multiple yarns Y. Guide rollers 36 and 37 are disposed adjacent to the right side wall 38a of the main body 38 outside the insulation box 30. Guide rollers 36 and 37 are arranged vertically, with guide roller 36 positioned below and guide roller 37 positioned above. Furthermore, guide roller 36 is positioned upstream in the yarn travel direction of the second group of yarns Y2, and guide roller 37 is positioned downstream in the yarn travel direction of the second group of yarns Y2.

[0087] Furthermore, guide rollers 36 and 37 are rotatable rollers with a rotation axis extending in the front-to-back direction. Guide rollers 36 and 37 are preferably driven rollers rotated by an electric motor (not shown), but they can also be driven rollers rotated by friction from the second set of yarns Y2. Alternatively, guide rollers 36 and 37 can be configured as driven rollers that can rotate with reduced friction with the second set of yarns Y2 or without contact with them, by ejecting gas from their surfaces. Furthermore, if guide rollers 36 and 37 are driven rollers, the tension of yarn Y can be adjusted by the rotational speed of guide rollers 36 and 37, thus facilitating control of yarn Y quality.

[0088] In the spinning and stretching apparatus 3 configured as described above, the first group of yarn Y1 is introduced into the interior of the heat preservation box 30 via the feed roller 12 from the inlet 30a. Inside the heat preservation box 30, it travels wound around guide rollers 31-33, which serve as preheating rollers, and guide rollers 34 and 35, which serve as heat setting rollers. Specifically, the first group of yarn Y1 is wound and travels in a zigzag pattern in the order of guide rollers 31, 32, 33, 34, and 35. The first group of yarn Y1 is heated to a temperature (above the glass transition point) that allows it to be stretched by the guide rollers 31-33, which serve as preheating rollers. After preheating, the first group of yarn Y1 becomes a fully stretched yarn due to the difference in feeding speed between guide rollers 33 and 34. Furthermore, the first group of yarn Y1 is heat-set by the guide rollers 34 and 35 while in a stretched state. Then, the first group of yarns Y1, after heat setting, is led out from the outlet 30b to the outside of the heat preservation box 30 and conveyed to the feed roller 13.

[0089] On the other hand, the second set of yarn Y2 is wound around the guide rollers 36 and 37 outside the heat preservation box 30 and travels to the feed roller 13. Therefore, the second set of yarn Y2 does not travel on the guide rollers 31 to 35 and is not heated or stretched, and is transported to the feed roller 13 as part of the orientation yarn.

[0090] The first set of yarn Y1, fed to the feed roller 13 via the outlet 30b of the insulation box 30, and the second set of yarn Y2, fed to the feed roller 13 via guide rollers 36 and 37, converge on the circumferential surface of the feed roller 13, traveling with the corresponding yarns overlapping each other. The first set of yarn Y1 and the second set of yarn Y2, fed to the feed roller 13, further reach the yarn combining device 16 via the feed roller 14. Then, the first set of yarn Y1 and the second set of yarn Y2 are combined by the yarn combining device 16 to form a mixed yarn Y3. The mixed yarn Y3 is then wound by the winding device 4 via the feed roller 15.

[0091] [Wire-hanging unit]

[0092] Figure 4 This is a perspective view showing the wire-hanging unit 5 according to the first embodiment of the present invention. Figure 5 This is a side view of unit 5 for hanging wire. Figure 6 as well as Figure 7 This diagram shows the state in which the yarn-hanging unit 5 is installed in the insulation box 30 of the spinning and stretching device 3 of the mixed yarn manufacturing device 1. Figure 6 It's a 3D image. Figure 7 It's a side view. Also, Figure 6 as well as Figure 7 The diagram shows the insulated box 30 with its door 39 open. See below for reference. Figures 4-7 Unit 5 will be used to explain the wire hanging process.

[0093] In the mixed yarn manufacturing apparatus 1, which manufactures mixed yarn Y3 by combining the first group of yarn Y1 and the second group of yarn Y2, a yarn-hanging unit 5 is used during the yarn-hanging operation of winding the second group of yarn Y2 onto the guide roller 36 and winding the first group of yarn Y1 onto multiple guide rollers 31 to 35. Furthermore, the yarn-hanging unit 5 is configured to include a mounting part 51 and a yarn-hanging part 52.

[0094] The mounting part 51 is configured in the wire-hanging unit 5 to be detachably mounted to the main body 38 of the insulation box 30. The mounting part 51 has a base 51a and a plurality of hooks 51b (two in this embodiment). The base 51a is configured as an elongated and plate-shaped member. The base 51a is configured to extend in a straight line in the length direction. When the mounting part 51 is mounted to the main body 38, the base 51a is configured to extend along the edge of the right side wall 38b of the main body 38.

[0095] Two hooks 51b are configured to engage with the right side wall 38b of the housing body 38 when the mounting part 51 is installed relative to the housing body 38. Each hook 51b is integrally connected to the base 51a and cantilevered out of the base 51a in a direction perpendicular to the length direction of the base 51a. The two hooks 51b are configured to protrude from the base 51a in the same direction. When the mounting part 51 is arranged along the side wall 38b of the housing body 38, the two hooks 51b are positioned corresponding to the two locking grooves 38c of the side wall 38b.

[0096] Furthermore, each hook portion 51b is provided with an engaging claw 51c. This engaging claw 51c is configured to bend and extend in a claw-like shape at its front end, which cantilevered from the base 51a, and engage with the locking groove 38c of the side wall 38b of the box body 38. When the mounting portion 51b is installed on the box body 38, each hook portion 51b is inserted into the locking groove 38c provided on the side wall 38b of the box body 38. Then, with each hook portion 51b inserted into the locking groove 38c, the mounting portion 51b is operated to shift its position downwards, and the engaging claw 51c at the front end of each hook portion 51b engages with the stepped portion within the locking groove 38c. Through the engagement of the engaging claw 51c of the hook portion 51b with the stepped portion within the locking groove 38c, the mounting portion 51 is mounted on the box body 38 and held therein. Furthermore, in this embodiment, the mounting part 51 is installed on the box body 38 by engaging the hook 51b with the locking groove 38c. However, this is not necessary; the mounting part 51 can be configured to be easily installed and detached from the box body 38. For example, it is also possible to provide a groove different from the locking groove 38c on the side wall 38b of the box body 38, and to easily install and detach the mounting part 51 from the box body 38 by engaging the hook 51b with the groove provided on the side wall 38b.

[0097] The wire-hanging part 52 is configured to hook the second set of wires Y2 when the mounting part 51 is installed on the housing body 38, and to hook the second set of wires Y2 during wire-hanging operations using the wire-hanging unit 5. Furthermore, as... Figure 6 as well as Figure 7 As shown, the wire-hanging portion 52 is configured to extend along the edge of the side wall 38b of the box body 38, which is closer to the guide rollers 36 and 37 than the plurality of guide rollers 31 to 35 and is located between the plurality of guide rollers 31 to 35 and the guide rollers 36 and 37, when the mounting portion 51 is mounted on the box body 38. Furthermore, the wire-hanging portion 52 is configured to extend along the edge of the side wall 38b of the box body 38 at a position that protrudes outward from the plurality of guide rollers 31 to 35 and at a position that protrudes axially from the end faces of the plurality of guide rollers 31 to 35 when the mounting portion 51 is mounted on the box body 38.

[0098] Specifically, the wire-hanging portion 52 is configured to have a rod-shaped portion 52a and a pair of feet 52b. The rod-shaped portion 52a is a rod-shaped portion extending parallel to the length direction of the base 51a of the mounting portion 51. In this embodiment, the rod-shaped portion 52a is a circular rod-shaped portion extending linearly in a circular cross-section. Furthermore, the rod-shaped portion 52a is configured to extend linearly in the vertical direction along the edge of the side wall 38b of the box body 38, which is closer to the guide rollers 36 and 37 than the plurality of guide rollers 31 to 35, and is located on the front edge of the side wall 38a of the box body 38 between the plurality of guide rollers 31 to 35 and the guide rollers 36 and 37. In addition, the rod-shaped portion 52a is configured to extend in the vertical direction from a position corresponding to the height position of the upper half of the guide roller 34 to a position corresponding to the height position of the lower half of the guide roller 31, when the mounting portion 51 is mounted on the box body 38.

[0099] The pair of legs 52b of the hanging part 52 are configured as shorter rod-shaped portions protruding from the base 51a and supporting the rod-shaped part 52a. Each pair of legs 52b is configured to protrude from the base 51a in a direction perpendicular to the length direction of the base 51a, opposite to the side protruding from the hook part 51b. Furthermore, each pair of legs 52b protrudes from both ends of the base 51a, specifically from the upper and lower ends of the base 51a when the mounting part 51 is mounted on the box body 38. Each leg 52b is fixed to the base 51a at one end and integrally joined to the rod-shaped part 52a at the other end. Additionally, one end of one pair of legs 52b is integrally joined to one end of the rod-shaped part 52a, and the other end of the other pair of legs 52b is integrally joined to the other end of the rod-shaped part 52a. Therefore, with the mounting portion 51 installed on the box body 38, the foot portion 52b protrudes forward in a horizontal direction relative to the edge of the side wall 38b of the box body 38. Furthermore, the rod-shaped portion 52a is configured to extend vertically parallel to the edge of the side wall 38b at a position away from the edge of the side wall 38b when the mounting portion 51 is installed on the box body 38.

[0100] According to the above configuration, the rod-shaped portion 52a of the wire-hanging portion 52 is configured to extend parallel to the length direction of the base 51a when separated from the base 51a of the mounting portion 51 by a distance equivalent to the length of the foot portion 52b. Furthermore, the rod-shaped portion 52a of the wire-hanging portion 52 is configured to extend linearly at a position where it is separated from the base 51a of the mounting portion 51 by the length of the foot portion 52b, and when the mounting portion 51 is mounted on the housing body 38, it extends along the edge of the housing body 38 at a position protruding beyond the end faces of the guide rollers 31-35 in the axial direction of the guide rollers 31-35.

[0101] In this embodiment, the mounting portion 51 and the wire-hanging portion 52 of the wire-hanging unit 5 are integrally provided, but this is not always the case. Alternatively, the mounting portion 51 and the wire-hanging portion 52 can be configured separately, with the wire-hanging portion 52 being detachably mounted to and detached from the mounting portion 51.

[0102] [Wire hanging operation using a wire hanging unit]

[0103] Figures 8 to 14 This diagram illustrates the state of the wire-hanging operation using the wire-hanging unit 5 in the mixed-fiber manufacturing apparatus 1. (Refer to...) Figures 6 to 14 The method of using the wire hanging unit 5 to perform wire hanging operation in the mixed wire manufacturing apparatus 1 will be explained.

[0104] In manufacturing the blended yarn Y3, firstly, before manufacturing the blended yarn Y3, the multiple yarns Y spun from the spinning device 2 are divided into a first group of yarns Y1 and a second group of yarns Y2. While the second group of yarns Y2 is wound onto the guide roller 36, a yarn-winding operation is performed, winding the first group of yarns Y1 onto multiple guide rollers 31-35. During the yarn-winding operation, as follows... Figure 6 as well as Figure 7 As shown, firstly, with the door 39 of the insulation box 30 open, a wire-hanging unit 5 is installed relative to the box body 38 of the insulation box 30, closer to the guide rollers 36 and 37 than the multiple wire guide rollers 31-35. At this time, the operator performing the wire-hanging operation (not shown) engages the hook 51b of the mounting part 51 with the locking groove 38c of the side wall 38b of the box body 38, thus installing the wire-hanging unit 5 onto the box body 38. Furthermore, with the wire-hanging unit 5 installed on the box body 38, the wire-hanging part 52 of the wire-hanging unit 5 is configured to extend along the edge of the side wall 38b of the box body 38, protruding from the end faces of the multiple wire guide rollers 31-35 in the axial direction.

[0105] Figure 8 This diagram shows the state of the first group of yarn Y1 wound around the outside of the insulation box 30, on the feed roller 12, and the second group of yarn Y2 wound around the guide roller 36. (Refer to...) Figure 8After the yarn-hanging unit 5 is installed on the main body 38, the operator then uses the suction gun 100 to draw in multiple yarns Y spun from the spinning device 2, while dividing the multiple yarns Y into a first group of yarns Y1 and a second group of yarns Y2. Furthermore, the suction port 100a for drawing in the multiple yarns Y is located at the front end of the suction gun 100, and the suction gun 100 is connected to a suction device (not shown in the diagram).

[0106] When the operator separates multiple yarns Y into group 1 yarns Y1 and group 2 yarns Y2, the multiple yarns Y sucked in by the suction gun 100 are temporarily wound onto the guide roller 36. Then, the operator performs the following operation: holding the suction gun with one hand and holding a yarn separating tool (not shown) that can hook the yarns on the front end side with the other hand, the operator separates the spun yarns into group 1 yarns Y1 and group 2 yarns Y2 using the yarn separating tool held in the other hand. Next, while keeping group 2 yarns Y2 wound on the guide roller 36, the operator operates the yarn separating tool to wind group 1 yarns Y1 onto the feed roller 12. When the state is such that group 2 yarns Y2 are wound on the guide roller 36 and group 1 yarns Y1 are wound on the feed roller 12, the operator puts down the yarn separating tool and holds the suction gun 100 with both hands. Then, the operator holds the suction gun 100 with both hands and manipulates its position so that the suction port 100a of the suction gun 100 moves between the guide roller 31 and the wire hanging part 52 of the wire hanging unit 5. Thus, as... Figure 8 As shown, the first set of yarn Y1, which is wound on the feeding roller 12, passes through the inlet 30a of the box body 38, and the second set of yarn Y2, which is wound on the guide roller 36, passes through the rod-shaped part 52a while hooked on the outer periphery of the rod-shaped part 52a of the yarn hanging part 52.

[0107] Figure 9 This diagram shows the state where the first group of yarn Y1 is wound on the first guide roller 31 in the direction of yarn travel. When the first group of yarn Y1 passes through the inlet 30a and the second group of yarn Y2 passes through the guide roller 36 and the yarn hanging part 52, the operator operates the position of the suction gun 100 with the suction port 100a inserted into the inside of the housing body 38. At this time, as... Figure 9 As shown, the operator uses both hands to operate the suction gun 100 so that the suction port 100a moves along the outer periphery of the guide roller 31. Figure 9The first group of yarn Y1 is wound clockwise along the yarn travel direction of the first group of yarn Y1 onto the guide roller 31. Furthermore, while the first group of yarn Y1 is wound onto the guide roller 31, the second group of yarn Y2, in the yarn channel from the guide roller 36 to the suction port 100a of the suction gun 100, is hooked onto the hanging part 52, which extends beyond the end face of the guide roller 31. Therefore, when the suction gun 100 is operated to wind the first group of yarn Y1 onto the guide roller 31, the yarn channel of the second group of yarn Y2 is maintained in a state where it protrudes beyond the end face of the guide roller 31. Thus, when the first group of yarn Y1 is wound onto the guide roller 31, it is possible to prevent the second group of yarn Y2 from being wound onto the guide roller 31 with the same yarn channel as the first group of yarn Y1.

[0108] Figure 10 This diagram shows the state where the first group of yarn Y1 is wound around the second guide roller 32 in the direction of yarn travel. When the first group of yarn Y1 has passed the first guide roller 31 in the direction of yarn travel, the operator further operates the position of the suction gun 100 while inserting the suction port 100a of the suction gun 100 into the inside of the housing body 38. At this time, as... Figure 10 As shown, the operator uses both hands to operate the suction gun 100 so that the suction port 100a moves along the outer periphery of the guide roller 32. Figure 10 The yarn moves counterclockwise. As a result, the first group of yarns Y1 is wound onto the guide roller 32 along the yarn travel direction of the first group of yarns Y1. Furthermore, while the first group of yarns Y1 is wound onto the guide roller 32, the second group of yarns Y2, in the yarn channel from the guide roller 36 to the suction port 100a of the suction gun 100, is hooked onto the hanging part 52, which extends beyond the end face of the guide roller 32. Therefore, when the suction gun 100 is operated to wind the first group of yarns Y1 onto the guide roller 32, the yarn channel of the second group of yarns Y2 is maintained in a state where it protrudes beyond the end face of the guide roller 32. Thus, when the first group of yarns Y1 is wound onto the guide roller 32, it is possible to prevent the second group of yarns Y2 from being wound onto the guide roller 32 with the same yarn channel as the first group of yarns Y1.

[0109] Figure 11 This diagram shows the state where the first group of yarn Y1 is wound around the third guide roller 33 in the direction of yarn travel. When the first group of yarn Y1 has passed the second guide roller 32 in the direction of yarn travel, the operator further operates the position of the suction gun 100 while inserting the suction port 100a of the suction gun 100 into the inside of the housing body 38. At this time, as... Figure 11 As shown, the operator uses both hands to operate the suction gun 100 so that the suction port 100a moves along the outer periphery of the guide roller 33. Figure 11The yarn moves clockwise. As a result, the first group of yarns Y1 is wound onto the guide roller 33 along the yarn travel direction of the first group of yarns Y1. Furthermore, while the first group of yarns Y1 is wound onto the guide roller 33, the second group of yarns Y2, in the yarn channel from the guide roller 36 to the suction port 100a of the suction gun 100, is hooked onto the hanging part 52, which extends beyond the end face of the guide roller 33. Therefore, when the suction gun 100 is operated to wind the first group of yarns Y1 onto the guide roller 33, the yarn channel of the second group of yarns Y2 is maintained in a state where it protrudes beyond the end face of the guide roller 33. Thus, when the first group of yarns Y1 is wound onto the guide roller 33, it is possible to prevent the second group of yarns Y2 from being wound onto the guide roller 33 with the same yarn channel as the first group of yarns Y1.

[0110] Figure 12 This diagram shows the state where the first group of yarn Y1 is wound around the fourth guide roller 34 in the direction of yarn travel. When the first group of yarn Y1 has passed the third guide roller 33 in the direction of yarn travel, the operator further operates the position of the suction gun 100 while the suction port 100a of the suction gun 100 is inserted into the inside of the housing body 38. At this time, as... Figure 12 As shown, the operator uses both hands to operate the suction gun 100 so that the suction port 100a moves along the outer periphery of the guide roller 34. Figure 12 The yarn moves counterclockwise. As a result, the first group of yarns Y1 is wound onto the guide roller 34 along the yarn travel direction of the first group of yarns Y1. Furthermore, while the first group of yarns Y1 is wound onto the guide roller 34, the second group of yarns Y2, in the yarn channel from the guide roller 36 to the suction port 100a of the suction gun 100, is hooked onto the hanging part 52, which extends beyond the end face of the guide roller 34. Therefore, when the suction gun 100 is operated to wind the first group of yarns Y1 onto the guide roller 34, the yarn channel of the second group of yarns Y2 is maintained in a state where it protrudes beyond the end face of the guide roller 34. Thus, when the first group of yarns Y1 is wound onto the guide roller 34, it is possible to prevent the second group of yarns Y2 from being wound onto the guide roller 34 with the same yarn channel as the first group of yarns Y1.

[0111] Figure 13 This diagram shows the state where the first group of yarn Y1 is wound around the fifth guide roller 35 in the direction of yarn travel. When the first group of yarn Y1 has passed the fourth guide roller 34 in the direction of yarn travel, the operator further operates the position of the suction gun 100 while the suction port 100a of the suction gun 100 is inserted into the inside of the housing body 38. At this time, as... Figure 13 As shown, the operator uses both hands to operate the suction gun 100 so that the suction port 100a moves along the outer periphery of the guide roller 35. Figure 12The yarn moves clockwise. As a result, the first group of yarns Y1 is wound onto the guide roller 35 along the yarn travel direction of the first group of yarns Y1. Furthermore, while the first group of yarns Y1 is wound onto the guide roller 35, the second group of yarns Y2, in the yarn channel from the guide roller 36 to the suction port 100a of the suction gun 100, is hooked onto the hanging part 52, which extends beyond the end face of the guide roller 35. Therefore, when the suction gun 100 is operated to wind the first group of yarns Y1 onto the guide roller 35, the yarn channel of the second group of yarns Y2 is maintained in a state where it protrudes beyond the end face of the guide roller 35. Thus, when the first group of yarns Y1 is wound onto the guide roller 35, it is possible to prevent the second group of yarns Y2 from being wound onto the guide roller 35 with the same yarn channel as the first group of yarns Y1.

[0112] Figure 14 This diagram shows the state where the first group of yarn Y1 is wound on all guide rollers 31-35 and the second group of yarn Y2 is wound on guide rollers 36 and 37. When the first group of yarn Y1 passes through all guide rollers 31-35, as shown... Figure 14 As shown, the operator positions the suction gun 100 so that its suction port 100a passes through the discharge port 30b. This causes the thread channel of the first group of threads Y1 to be in a state where it passes through the discharge port 30b. When the first group of threads Y1 passes through the discharge port 30b, and the suction port 100a of the suction gun 100 is moved from the discharge port 30b to the outside of the housing body 38, the second group of threads Y2 wound on the guide roller 36 disengages from the thread hanging portion 52 of the thread hanging unit 5. Then, the operator further operates the suction gun 100 with both hands so that the suction port 100a of the suction gun 100 moves along the outer periphery of the guide roller 37... Figure 14 The spinning device moves clockwise. Consequently, the second group of yarns Y2, wound on the guide roller 36, is also wound on the guide roller 37 along the direction of travel of the second group of yarns Y2. As described above, the multiple yarns Y spun from the spinning device 2 are divided into a first group of yarns Y1 and a second group of yarns Y2. The second group of yarns Y2 is wound on the guide roller 36, and the winding operation of the first group of yarns Y1 on the multiple guide rollers 31-35 is completed. Furthermore, by operating the suction gun 100, which draws in the first group of yarns Y1 from the outlet 30b and the second group of yarns Y2 via the guide roller 37, the first group of yarns Y1 and the second group of yarns Y2 are wound onto the feed rollers 13-15, and then pulled towards the take-up device 4.

[0113] [Effects]

[0114] As explained above, according to the first embodiment of the present invention, when a yarn hanging operation is performed in the mixed yarn manufacturing apparatus 1 during the manufacturing of the mixed yarn Y3, firstly, a yarn hanging unit 5 is installed at the edge of the main body 38 of the housing 38, which is closer to the guide rollers 36 and 37 than the plurality of guide rollers 31 to 35. At this time, the yarn hanging portion 52 of the yarn hanging unit 5 is configured to extend along the edge of the housing 38 at a position protruding from the end faces of the plurality of guide rollers 31 to 35 in the axial direction. And, in this state, the yarn hanging operation is performed. When the yarn hanging operation begins, the operator draws in the plurality of yarns Y spun from the spinning apparatus 2 with the suction gun 100, and divides the plurality of yarns Y into a first group of yarns Y1 and a second group of yarns Y2. The separated second group of yarns Y2 is wound onto the guide rollers 36, which are positioned closer to the yarn hanging unit 5 than the plurality of guide rollers 31 to 35. Furthermore, the operator, while holding the suction gun 100 that draws in multiple threads Y with both hands, operates the position of the suction gun 100 to sequentially wind the first group of threads Y1 relative to the multiple guide rollers 31-35. At this time, the second group of threads Y2, wound on the guide roller 36 and attracted by the suction gun, is hooked in the thread channel from the guide roller 36 to the suction port 100a of the suction gun 100, at a position that protrudes outward from the multiple guide rollers 31-35 toward the box body 38 and protrudes axially from the end face of the guide rollers 31-35, extending along the edge of the box body 38. Therefore, while the operator operates the suction gun 100 with both hands to sequentially wind the first group of threads Y1 relative to the multiple guide rollers 31-35, the second group of threads Y2 remains hooked on the hooking part 52 of the hooking unit 5. Therefore, during the operation of winding the first group of yarn Y1 onto the multiple guide rollers 31-35, the yarn channel of the second group of yarn Y2 is maintained in a position where a portion of the yarn channel of the second group of yarn Y2 located between the guide roller 36 and the suction gun 100 is wound to a position that protrudes outward from the multiple guide rollers 31-35 toward the box body 38 and protrudes axially from the end face of the guide rollers 31-35. Thus, it is possible to prevent the second group of yarn Y2 from being wound onto the guide rollers 31-35 with the same yarn channel as the first group of yarn Y1. Therefore, the operator can easily perform the winding operation of the first group of yarn Y1 relative to the multiple guide rollers 31-35 while maintaining the separation of the yarn channels of the first group of yarn Y1 and the second group of yarn Y2 by operating the weighted suction gun 100 with both hands. Furthermore, because the wire-hanging operation can be performed easily, the operation time required for wire-hanging can be significantly reduced. In addition, by significantly reducing the operation time for wire-hanging, the amount of wire sucked in by the suction gun 100 during the operation can be reduced, and the amount of spun wire generated can be significantly reduced.

[0115] Therefore, according to the first embodiment of the present invention, it is possible to provide a wire-hanging unit 5 and a mixed-filament manufacturing apparatus having the wire-hanging unit 5: the wire-hanging operation of sequentially winding the first group of filaments Y1 relative to a plurality of guide rollers 31 to 35 while operating the suction gun 100 with both hands can be easily performed, the operation time required for the wire-hanging operation can be greatly shortened, and the amount of filaments sucked in by the suction gun 100 can be reduced, thereby greatly reducing the amount of filaments generated.

[0116] Furthermore, according to the first embodiment of the present invention, the wire-hanging unit 5 can be easily constructed with a simple structure having a wire-hanging portion 52 having a rod-shaped portion 52a extending in a straight line and a mounting portion 51 to the box body 38. That is, the wire-hanging unit 5 can be easily constructed with a simple structure to maintain the wire channels of the first group of wires Y1 and the second group of wires Y2 separated while operating the suction gun 100 with both hands, and to easily perform the wire-hanging operation of winding the first group of wires Y1 onto the plurality of guide rollers 31 to 35.

[0117] (First variation)

[0118] Next, a first variation of the first embodiment of the present invention will be described. Figure 15 This is a three-dimensional view of the wire-hanging unit 6 in the first modified example. Figure 16 This is a side view of unit 6 for hanging wire. Figure 17 This is a perspective view showing the state in which the yarn-hanging unit 6 is installed in the insulation box 30 of the spinning and stretching device 3 of the mixed yarn manufacturing apparatus 1. The yarn-hanging unit 6 in the first modified example... Figure 1 It is used in the hybrid filament manufacturing apparatus 1 shown. Furthermore, the hybrid filament manufacturing apparatus of the first modified example is configured to include... Figure 1 The hybrid filament manufacturing apparatus 1 and shown Figure 15 and Figure 16 The device for the wire-hanging unit 6 is shown. Furthermore, in the description of the first modified example, the configuration of the wire-hanging unit 6, which differs from the first embodiment described above, will be explained. Configurations identical to those in the first embodiment will be labeled with the same symbols or referenced in the drawings, thus omitting repeated descriptions.

[0119] The wire-hanging unit 6 is configured to include a mounting portion 61 and a wire-hanging portion 62. The mounting portion 61 is configured to be easily installed and detached from the main body 38 of the insulation box 30 within the wire-hanging unit 6. The mounting portion 61 has a base 61a and a plurality of hook portions 61b (two in this embodiment). The base 61a is configured to be elongated and plate-shaped. The base 61a extends linearly in the length direction. When the mounting portion 61 is installed relative to the main body 38, the base 61a is positioned extending along the edge of the right-side side wall 38b of the main body 38.

[0120] Two hooks 61b are respectively configured to engage with the right side wall 38b of the box body 38 when the mounting part 61 is installed relative to the box body 38. The hooks 61b are constructed in the same manner as the hooks 51b of the wire-hanging unit 5 in the first embodiment. The hooks 61b are integrally provided with the base 61a and protrude from the base 61a in a direction perpendicular to the length direction of the base 61a. Furthermore, a hook claw 61c is provided on the front end side of the hook 61b, which extends in a hook-like shape and engages with the locking groove 38c of the side wall 38b of the box body 38. When the mounting part 61 is installed on the box body 38, the position of the mounting part 61 is adjusted so that each hook 61b is inserted into each locking groove 38c of the box body 38, and the hook claw 61c of each hook 61b engages with the stepped portion in each locking groove 38c. The mounting part 61 is held in place on the box body 38 by engaging the hook 61b with the locking groove 38c. In this modified example, the mounting part 61 is mounted to the box body 38 by engaging the hook 61b with the locking groove 38c, but this is not necessary; the mounting part 61 can be configured to be easily installed and removed from the box body 38. For example, it is also possible to provide a groove different from the locking groove 38c on the side wall 38b of the box body 38, and to easily install and remove the mounting part 61 from the box body 38 by engaging the hook 61b with the groove on the side wall 38b.

[0121] The wire-hanging part 62 is configured to hook the second set of wires Y2 when the mounting part 61 is installed on the housing body 38, and hooks the second set of wires Y2 during wire-hanging operations using the wire-hanging unit 6. Furthermore, as... Figure 17 As shown, the wire-hanging portion 62 is configured to extend along the edge of the side wall 38b of the box body 38, which is closer to the guide rollers 36 and 37 than the plurality of guide rollers 31-35, and is located between the plurality of guide rollers 31-35 and the guide rollers 36 and 37. Furthermore, the wire-hanging portion 62 is configured to extend along the edge of the side wall 38b of the box body 38 at a position that protrudes outward from the plurality of guide rollers 31-35 than the end faces of the plurality of guide rollers 31-35 in the axial direction of the guide rollers 31-35, when the mounting portion 61 is mounted on the box body 38.

[0122] Specifically, the wire-hanging portion 62 is configured to have a flat plate portion 62a and a flat plate portion 62b formed by bending a plate-shaped component integrally provided with the base 61a of the mounting portion 61. The flat plate portions 62a and 62b are flat plate-shaped portions extending parallel to the length direction of the base 61a. One of the two edges of the flat plate portion 62a extending along the length direction is integrally joined to the base 61a. The other edge of the flat plate portion 62a extending along the length direction is integrally joined to the flat plate portion 62b. Furthermore, the base 61a, flat plate portion 62a, and flat plate portion 62b are integrally configured such that, in a cross-section perpendicular to the length direction of the base 61a and the wire-hanging portion 62, they form an isosceles triangle with the base portion 61a as the base and the portions of the flat plate portion 62a and the flat plate portion 62b as equal sides. Furthermore, the wire-hanging portion 62, which is configured to have a flat plate portion 62a and a flat plate portion 62b, is formed, for example, by bending a plate-shaped component that is the raw material of the base portion 61a and the wire-hanging portion 62 into a triangular prism shape.

[0123] Furthermore, both flat plate portions 62a and 62b are configured such that, with the mounting portion 61 mounted on the housing body 38, they extend in a flat shape in the vertical direction along the edge of the side wall 38b of the housing body 38, which is closer to the guide rollers 36 and 37 than the plurality of guide rollers 31-35, and are located on the front edge of the side wall 38a of the housing body 38 between the guide rollers 31-35 and the guide rollers 36 and 37. Moreover, both flat plate portions 62a and 62b are configured such that, with the mounting portion 61 mounted on the housing body 38, they extend in the vertical direction from a position corresponding to the height of the upper half of the guide roller 34 to a position corresponding to the height of the lower half of the guide roller 31.

[0124] Furthermore, the wire-hanging part 62, which is configured to have integrally formed flat plate parts 62a and 62b, is provided with a top 62c, which serves as the joint portion of the flat plate parts 62a and 62b. When the wire-hanging operation using the wire-hanging unit 6 is performed with the mounting part 61 installed on the housing body 38, the second set of wires Y2 is hooked onto the wire-hanging part 62 at the top 62c. In a cross-section perpendicular to the length direction of the base 61a and the wire-hanging part 62, the top 62c of the wire-hanging part 62 is formed as the vertex portion of an isosceles triangle with the base 61a as the base and the portions of the flat plate parts 62a and 62b as equal sides. The top 62c is positioned on the side opposite to the hook portion 61b relative to the base 61a. Furthermore, the top 62c is configured to extend vertically parallel to the edge of the side wall 38b at a position away from the edge of the side wall 38b when the mounting part 61 is mounted on the box body 38. Therefore, the wire-hanging part 62 is configured such that, at the top 62c, it extends parallel to the length direction of the base 51a at a distance equal to the height of the portion of the flat plate 62a and the portion of the flat plate 62b forming an isosceles triangle with two equal sides. Furthermore, the top 62c of the wire-hanging part 62 is configured to extend linearly at a position away from the base 51a of the mounting part 51, and when the mounting part 51 is mounted on the box body 38, it extends along the edge of the box body 38 at a position protruding beyond the end faces of the guide rollers 31-35 in the axial direction of the guide rollers 31-35.

[0125] When using the aforementioned yarn-hanging unit 6 for yarn-hanging operations, the yarn-hanging unit 6 is used in the same way as the aforementioned yarn-hanging unit 5. During the yarn-hanging operation, firstly, the yarn-hanging unit 6 is installed on the main body 38 of the insulation box 30. At this time, the top 62c of the yarn-hanging portion 62 of the yarn-hanging unit 6 is positioned such that it protrudes along the edge of the side wall 38b of the main body 38, protruding from the end faces of the guide rollers 31-35 in the axial direction. Then, in this state, the yarn-hanging operation is performed. When the yarn-hanging operation begins, the operator draws in multiple yarns Y spun from the spinning device 2 using the suction gun 100, while dividing the multiple yarns Y into a first group of yarns Y1 and a second group of yarns Y2. The separated second group of yarns Y2 is wound onto the guide rollers 36 positioned on the side of the yarn-hanging unit 6 relative to the multiple guide rollers 31-35. Furthermore, the operator then holds the suction gun 100, which sucks in multiple threads Y, with both hands, and operates the position of the suction gun 100 to sequentially wind the first group of threads Y1 relative to the multiple guide rollers 31-35. At this time, the second group of threads Y2, wound on the guide roller 36 and sucked in by the suction gun, is hooked in the thread channel from the guide roller 36 to the suction port 100a of the suction gun 100, at a position that protrudes outward from the multiple guide rollers 31-35 toward the box body 38 and at a position that protrudes axially from the end faces of the guide rollers 31-35 along the edge of the box body 38. Therefore, while the operator operates the suction gun 100 with both hands to sequentially wind the first group of threads Y1 relative to the multiple guide rollers 31-35, the second group of threads Y2 is kept hooked on the hooking part 62 of the hooking unit 6. Therefore, during the operation of winding the first group of yarn Y1 onto the multiple guide rollers 31-35, the yarn channel of the second group of yarn Y2 is maintained in the following state: a portion of the yarn channel of the second group of yarn Y2 located between the guide roller 36 and the suction gun 100 is wound to a position that protrudes outward from the multiple guide rollers 31-35 toward the box body 38 and is a position that protrudes beyond the end face of the guide rollers 31-35 in the axial direction. Therefore, it is possible to prevent the second group of yarn Y2 from being wound onto the guide rollers 31-35 with the same yarn channel as the first group of yarn Y1. Thus, the operator can easily perform the yarn winding operation of sequentially winding the first group of yarn Y1 relative to the multiple guide rollers 31-35 while maintaining the separation of the yarn channels of the first group of yarn Y1 and the second group of yarn Y2 using both hands operating the weighted suction gun 100. Furthermore, the ease of wire hanging operations significantly reduces the time required for these operations. This reduction in wire hanging time also decreases the amount of wire drawn into the suction gun 100 during the process, and drastically reduces the amount of spun wire generated.

[0126] Therefore, according to the first modification, it is possible to provide a wire-hanging unit 6 and a mixed-filament manufacturing apparatus equipped with the wire-hanging unit 6: the wire-hanging operation of sequentially winding the first group of filaments Y1 relative to the plurality of guide rollers 31 to 35 can be easily performed while operating the suction gun 100 with both hands, the operation time required for the wire-hanging operation can be greatly shortened, and the amount of filament sucked in by the suction gun 100 can be reduced, thereby greatly reducing the amount of filaments generated.

[0127] Furthermore, according to the first modified example, the wire-hanging unit 6 can be easily constructed with a simple structure having a wire-hanging portion 62 having a flat plate portion 62a and a flat plate portion 62b extending in a straight line and a mounting portion 61 to the box body 38. That is, the wire-hanging unit 6 can be easily constructed with a simple structure, allowing the wire-hanging operation of winding the first group of wire Y1 onto multiple guide rollers 31 to 35 while maintaining the wire channels of the first group of wire Y1 and the second group of wire Y2 separated by operating the suction gun 100 with both hands.

[0128] [Second Variation]

[0129] Next, a second variation of the first embodiment of the present invention will be described. Figure 18 This is a three-dimensional view of the wire-hanging unit 7 in the second modified example. Figure 19 This is a side view of unit 7 for hanging wire. Figure 20 This is a perspective view showing the state in which the yarn-hanging unit 7 is installed in the insulation box 30 of the spinning and stretching device 3 of the mixed yarn manufacturing apparatus 1. The yarn-hanging unit 7 in the second modified example... Figure 1 The hybrid filament manufacturing apparatus 1 shown is used in this apparatus. Furthermore, the hybrid filament manufacturing apparatus of the second modification is configured to include... Figure 1 The hybrid filament manufacturing apparatus 1 and shown Figure 18 as well as Figure 19 The device for the wire-hanging unit 7 is shown. Furthermore, in the description of the second variation, the configuration of the wire-hanging unit 7, which differs from that of the first embodiment, will be described. Configurations identical to those in the first embodiment will be labeled with the same symbols or referenced in the drawings, thus omitting repetitive descriptions.

[0130] The wire-hanging unit 7 is configured to include a mounting portion 71 and a wire-hanging portion 72. The mounting portion 71 is configured in the wire-hanging unit 7 to be detachably mounted to the main body 38 of the insulation box 30. The mounting portion 71 has a base 71a and a plurality of hook portions 71b (two in this embodiment). The base 71a is configured to be elongated and plate-shaped. The base 71a extends linearly in the length direction. When the mounting portion 71 is mounted to the main body 38, the base 71a is positioned extending along the edge of the right side wall 38b of the main body 38.

[0131] Two hooks 71b are respectively configured to engage with the right side wall 38b of the box body 38 when the mounting part 71 is installed relative to the box body 38. The hooks 71b are configured in the same way as the hooks 51b of the wire-hanging unit 5 in the first embodiment. The hooks 71b are integrally provided with the base 71a and protrude from the base 71a in a direction perpendicular to the length direction of the base 71a. Furthermore, a hook claw 71c is provided on the front end side of the hook 71b, which extends in a hook-like shape and engages with the locking groove 38c of the side wall 38b of the box body 38. When the mounting part 71 is installed on the box body 38, the position of the mounting part 71 is adjusted so that each hook 71b is inserted into each locking groove 38c of the box body 38, and the hook claw 71c of each hook 71b engages with the stepped portion in each locking groove 38c. The mounting part 71 is held in place on the box body 38 by engaging the hook 71b with the locking groove 38c. In this modified example, the mounting part 71 is mounted to the box body 38 by engaging the hook 71b with the locking groove 38c, but this is not necessary; the mounting part 71 can be configured to be easily installed and removed from the box body 38. For example, it is also possible to provide a groove different from the locking groove 38c on the side wall 38b of the box body 38, and to easily install and remove the mounting part 71 from the box body 38 by engaging the hook 71b with the groove on the side wall 38b.

[0132] The wire-hanging part 72 is configured to hook the second set of wires Y2 when the mounting part 71 is installed on the housing body 38, and hooks the second set of wires Y2 during wire-hanging operations using the wire-hanging unit 7. Furthermore, as... Figure 20 As shown, the wire-hanging portion 72 is configured to extend along the edge of the side wall 38b of the box body 38, which is closer to the guide rollers 36 and 37 than the plurality of guide rollers 31-35, and is located between the plurality of guide rollers 31-35 and the guide rollers 36 and 37. Furthermore, the wire-hanging portion 72 is configured to extend along the edge of the side wall 38b of the box body 38 at a position that protrudes outward from the plurality of guide rollers 31-35 than the plurality of guide rollers 31-35 in the axial direction of the plurality of guide rollers 31-35, when the mounting portion 71 is mounted on the box body 38.

[0133] Specifically, the wire-hanging portion 72 is configured to have a flat plate portion 72a formed by bending a plate-shaped component integrally provided with the base 71a of the mounting portion 71. The flat plate portion 72a is configured as a flat plate-shaped portion extending parallel to the length direction of the base 71a. One of the two edge portions of the flat plate portion 72a extending along the length direction is integrally joined to the base 71a. Furthermore, the base 71a and the flat plate portion 72a are integrally configured to have an L-shaped cross-sectional shape in a cross-section perpendicular to the length direction of the base 71a and the flat plate portion 72a, in which the portion constituting the base 71a is orthogonal to the portion of the flat plate portion 72a. In addition, the wire-hanging portion 72, which is configured to have the flat plate portion 72a, is formed, for example, by bending a plate-shaped component that serves as the raw material for the base 71a and the wire-hanging portion 72 in a manner that forms an L-shaped cross-section.

[0134] Furthermore, the flat plate portion 72a is configured such that, with the mounting portion 71 mounted on the housing body 38, it extends in a flat, vertical direction along the front edge of the side wall 38a of the housing body 38, closer to the guide rollers 36 and 37 than the plurality of guide rollers 31-35 and between the plurality of guide rollers 31-35 and the guide rollers 36 and 37. Moreover, the flat plate portion 72a is configured such that, with the mounting portion 71 mounted on the housing body 38, it extends vertically from a position corresponding to the height of the upper half of the guide roller 34 to a position corresponding to the height of the lower half of the guide roller 31.

[0135] Furthermore, in the wire-hanging portion 72, which is configured to have a flat plate portion 72a integrally connected to the base portion 71a, an edge portion 72b extending along the length direction of the wire-hanging portion 72 is provided at the end opposite to the end on the side integrally connected to the base portion 71a in the flat plate portion 72a. When a wire-hanging operation using the wire-hanging unit 7 is performed with the mounting portion 71 installed on the box body 38, the second set of wires Y2 is hooked onto the wire-hanging portion 72 at the edge portion 72b. The edge portion 72b is positioned on the side opposite to the hook portion 71b relative to the base portion 71a. Moreover, the edge portion 72b is configured to extend parallel to the edge portion of the side wall 38b in the vertical direction at a position away from the edge portion of the side wall 38b when the mounting portion 71 is installed on the box body 38. Therefore, the wire-hanging portion 72 is configured such that, at its edge portion 72b, it extends parallel to the length direction of the base 71a at a distance equivalent to the protrusion of the L-shaped protruding flat plate portion 72a relative to the base 71a. Furthermore, the edge portion 72b of the wire-hanging portion 72 is configured to extend linearly at a position away from the base 71a of the mounting portion 71, and, when the mounting portion 71 is mounted on the housing body 38, extends along the edge portion of the housing body 38 at a position where it protrudes axially from the end faces of the guide rollers 31-35.

[0136] When using the aforementioned yarn-hanging unit 7 for yarn-hanging operations, the yarn-hanging unit 7 is used in the same way as the aforementioned yarn-hanging unit 5. When performing the yarn-hanging operation, firstly, the yarn-hanging unit 7 is installed on the main body 38 of the insulation box 30. At this time, the edge portion 72b of the yarn-hanging part 72 of the yarn-hanging unit 7 is configured to extend along the edge portion of the side wall 38b of the main body 38 at a position protruding from the end faces of the multiple guide rollers 31-35 in the axial direction of the guide rollers 31-35. Then, in this state, the yarn-hanging operation is performed. When the yarn-hanging operation begins, the operator draws in multiple yarns Y spun from the spinning device 2 using the suction gun 100, while dividing the multiple yarns Y into a first group of yarns Y1 and a second group of yarns Y2. The separated second group of yarns Y2 is wound onto the guide rollers 36 arranged on the side of the yarn-hanging unit 7 relative to the multiple guide rollers 31-35. Furthermore, the operator, while holding the suction gun 100 that draws in multiple threads Y with both hands, manipulates the position of the suction gun 100 to sequentially wind the first group of threads Y1 relative to the multiple guide rollers 31-35. At this time, the second group of threads Y2, wound on the guide roller 36 and drawn in by the suction gun, is hooked in the thread channel from the guide roller 36 to the suction port 100a of the suction gun 100, at a position that protrudes outward from the multiple guide rollers 31-35 toward the box body 38 and at a position that protrudes axially from the end faces of the guide rollers 31-35 along the edge of the box body 38. Therefore, while the operator holds the suction gun 100 with both hands to sequentially wind the first group of threads Y1 relative to the multiple guide rollers 31-35, the second group of threads Y2 remains hooked on the hooking part 72 of the hooking unit 7. Therefore, during the operation of winding the first group of yarn Y1 onto the multiple guide rollers 31-35, the yarn channel of the second group of yarn Y2 is maintained in the following state: a portion of the yarn channel of the second group of yarn Y2 located between the guide roller 36 and the suction gun 100 is wound to a position that protrudes outward from the multiple guide rollers 31-35 toward the box body 38 and is a position that protrudes axially from the end face of the guide rollers 31-35. Therefore, it is possible to prevent the second group of yarn Y2 from being wound onto the guide rollers 31-35 with the same yarn channel as the first group of yarn Y1. Thus, the operator can easily perform the winding operation of the first group of yarn Y1 relative to the multiple guide rollers 31-35 while maintaining the separation of the yarn channels of the first group of yarn Y1 and the second group of yarn Y2 using both hands operating the weighted suction gun 100. Furthermore, because the wire-hanging operation can be performed easily, the operation time required for wire-hanging can be significantly reduced. In addition, by significantly reducing the operation time for wire-hanging, the amount of wire sucked into the suction gun 100 during the operation can be reduced, and the amount of spun wire generated can be significantly reduced.

[0137] Therefore, according to the second modification, a wire-hanging unit 7 and a mixed-filament manufacturing apparatus equipped with the wire-hanging unit 7 are provided: the wire-hanging operation of sequentially winding the first group of filaments Y1 relative to the plurality of guide rollers 31 to 35 can be easily performed while operating the suction gun 100 with both hands, the operation time required for the wire-hanging operation can be greatly shortened, and the amount of filament sucked in by the suction gun 100 can be reduced, thereby greatly reducing the amount of filaments generated.

[0138] Furthermore, according to the second modification, the wire-hanging unit 7 can be easily constructed with a simple structure having a wire-hanging portion 72 having a flat plate portion 72a extending in a straight line and a mounting portion 71 to the box body 38. That is, the wire-hanging unit 7 can be easily constructed with a simple structure, in which the wire-hanging operation of winding the first group of wire Y1 onto multiple guide rollers 31 to 35 can be easily performed while maintaining the wire channels of the first group of wire Y1 and the second group of wire Y2 separated by operating the suction gun 100 with both hands.

[0139] [3rd Variation]

[0140] Next, a third variation of the first embodiment of the present invention will be described. Figure 21 This is a perspective view showing the state of the yarn-hanging unit 8 of the third modification being installed in the insulation box 30 of the spinning and stretching device 3 of the mixed yarn manufacturing apparatus 1. The yarn-hanging unit 7 of the third modification is... Figure 1 It is used in the hybrid filament manufacturing apparatus 1 shown. Furthermore, the hybrid filament manufacturing apparatus of the third modification is configured to include... Figure 1 The hybrid filament manufacturing apparatus 1 and shown Figure 21 The device for the wire-hanging unit 8 is shown. Furthermore, in the description of the third variation, the configuration of the wire-hanging unit 8, which differs from that of the first embodiment, will be described. For configurations identical to those in the first embodiment, the same reference numerals will be used in the drawings, thus omitting repeated descriptions.

[0141] The wire-hanging unit 8 is a flat plate-shaped component mounted relative to the main body 38 of the insulation box 30, and is configured to include a mounting part 81 and a wire-hanging part 82. The mounting part 81, in the wire-hanging unit 8, is a portion that is fixedly mounted to the right side wall 38a of the main body 38 of the insulation box 30. The mounting part 81 is fixedly mounted relative to the side wall 38a on the outside of the side wall 38a, overlapping the surface of the side wall 38a. The mounting part 81 is connected to or welded to the side wall 38a using, for example, bolts or other fasteners, thereby fixing it to the main body 38.

[0142] The wire-hanging part 82 is integrally provided with the mounting part 81. In the wire-hanging unit 8, which is a flat component, it is a portion that protrudes forward from the mounting part 81, which is mounted on the side wall 38a of the box body 38. The wire-hanging part 82 is configured to hook the second set of wire Y2 when performing wire-hanging operations using the wire-hanging unit 8. Furthermore, as... Figure 21 As shown, the wire-hanging portion 82 is configured to extend in a flat, vertical direction along the edge of the side wall 38b of the housing body 38, which is closer to the guide rollers 36 and 37 than the plurality of guide rollers 31-35, and is located between the plurality of guide rollers 31-35 and the guide rollers 36 and 37. Furthermore, the wire-hanging portion 82 is configured to extend vertically from a position corresponding to the height of the upper half of the guide roller 34 to a position corresponding to the height of the lower half of the guide roller 31. Moreover, the wire-hanging portion 82 is configured to extend along the edge of the side wall 38b of the housing body 38 at a position protruding outward from the plurality of guide rollers 31-35 and at a position protruding axially from the end faces of the plurality of guide rollers 31-35.

[0143] Furthermore, the wire-hanging part 82, which is integrally provided with the mounting part 81, has an edge portion 82a extending along its length at the end opposite to the side integrally provided with the mounting part 81. During wire-hanging operations using the wire-hanging unit 8, the second set of wires Y2 is hooked onto the wire-hanging part 82 at the edge portion 82a. The wire-hanging part 82 protrudes forward from the edge portion of the side wall 38b of the box body 38, and the edge portion 82a of the wire-hanging part 82 is configured to extend parallel to the edge portion of the side wall 38b in the vertical direction at a position where it protrudes forward from the edge portion of the side wall 38b of the box body 38. Furthermore, the edge portion 82b of the wire-hanging part 82 is configured to extend along the edge portion of the box body 38 at a position where it protrudes beyond the end faces of the guide rollers 31-35 in the axial direction.

[0144] The aforementioned yarn-hanging unit 8 is always installed on the main body 38 of the insulation box 30. Furthermore, when performing yarn-hanging operations using the yarn-hanging unit 8, it is used while installed on the main body 38. During the yarn-hanging operation, the operator uses the suction gun 100 to draw in multiple yarns Y spun from the spinning device 2, while dividing the multiple yarns Y into a first group of yarns Y1 and a second group of yarns Y2. The separated second group of yarns Y2 is then wound onto the guide rollers 36, which are positioned closer to the yarn-hanging unit 8 than the multiple guide rollers 31-35. Then, the operator holds the suction gun 100, which draws in multiple yarns Y, with both hands, and manipulates the position of the suction gun 100 to sequentially wind the first group of yarns Y1 relative to the multiple guide rollers 31-35. At this time, the second set of yarn Y2, wound on the guide roller 36 and sucked into the suction gun, is hooked in the yarn channel from the guide roller 36 to the suction port 100a of the suction gun 100. This hook is located at a position protruding outwards from the multiple guide rollers 31-35 toward the box body 38, and at a position protruding axially from the end faces of the guide rollers 31-35 along the edge of the box body 38. Therefore, when the operator holds the suction gun 100 with both hands and performs the operation of sequentially winding the first set of yarn Y1 relative to the multiple guide rollers 31-35, the second set of yarn Y2 remains hooked to the hook of the hook of the hook of the hook unit 82. Therefore, during the operation of winding the first group of yarn Y1 onto the multiple guide rollers 31-35, the yarn path of the second group of yarn Y2 is maintained in the following state: it is wound between the guide roller 36 and the suction gun 100 to a position that protrudes outward from the multiple guide rollers 31-35 toward the main body 38, and is also a position that protrudes beyond the end face of the guide rollers 31-35 in the axial direction. Therefore, it is possible to prevent the second group of yarn Y2 from being wound onto the guide rollers 31-35 with the same yarn path as the first group of yarn Y1. Thus, the operator can easily perform the yarn winding operation of sequentially winding the first group of yarn Y1 relative to the multiple guide rollers 31-35 while maintaining a state where the yarn paths of the first group of yarn Y1 and the second group of yarn Y2 are separated by operating the weighted suction gun 100 with both hands. Furthermore, since the yarn winding operation can be performed easily, the operation time required for the yarn winding operation can be significantly reduced. In addition, by significantly shortening the operation time of the wire hanging operation, the amount of wire sucked in by the suction gun 100 during the operation can be reduced, and the amount of wire re-spinning generated can be greatly reduced.

[0145] Therefore, according to the third modification, it is possible to provide a wire-hanging unit 8 and a mixed-filament manufacturing apparatus equipped with the wire-hanging unit 8: the wire-hanging operation of sequentially winding the first group of filaments Y1 relative to the plurality of guide rollers 31 to 35 can be easily performed while operating the suction gun 100 with both hands, the operation time required for the wire-hanging operation can be greatly shortened, and the amount of filament sucked in by the suction gun 100 can be reduced, thereby greatly reducing the amount of filaments generated.

[0146] (Second Implementation)

[0147] Next, the second embodiment of the present invention will be described. Figure 22 It is used for attaching wire to the wire-hanging unit 5A (see reference 2) of the second embodiment of the present invention. Figure 25 The figure illustrates the mixed yarn manufacturing apparatus 1A of the present invention and the mixed yarn manufacturing apparatus of the second embodiment of the present invention, and is a front view of the mixed yarn manufacturing apparatus 1A which manufactures mixed yarn by performing heat setting (heat treatment) on some of the oriented yarns. Figure 23 It means Figure 22 Front view of the spinning and stretching device 3A in the mixed yarn manufacturing apparatus 1A shown. Figure 24 yes Figure 23 The three-dimensional view of the spinning and stretching device 3A shown. Figure 25 This is a perspective view showing the yarn-hanging unit 5A according to the second embodiment of the present invention. Furthermore, in the description of the second embodiment, the configuration of the spinning stretching device 3A and the yarn-hanging unit 5A, which differs from that of the first embodiment, will be described. For configurations identical to those in the first embodiment, the same reference numerals will be used or the same reference numerals will be used in the drawings, thereby omitting repeated descriptions.

[0148] [Spinning and stretching device]

[0149] Reference Figure 22 and even Figure 25 The spinning and stretching apparatus 3A is configured to include a heat preservation box 30A, multiple (five in the second embodiment) guide rollers 31-35 with heating sources, a guide roller 36A, and a yarn doubling auxiliary device 17. The spinning and stretching apparatus 3A is configured similarly to the spinning and stretching apparatus 3 of the first embodiment, but differs from the first embodiment in that it is configured to heat-set the second group of yarns Y2 in a partially oriented state through the guide rollers 34 and 35. Furthermore, in... Figure 23 In the diagram, the first group of silk thread Y1 is represented by a single-dotted line, the second group of silk thread Y2 is represented by a double-dotted line, and the mixed silk thread Y3 is represented by a solid line.

[0150] Reference Figure 22 and even Figure 24The insulation box 30A of the spinning and stretching apparatus 3A is constructed similarly to the insulation box 30 of the spinning and stretching apparatus 3 in the first embodiment, having a box body 38 for housing multiple guide rollers 31-35 and a door 39 for opening and closing the box body 38. However, the insulation box 30A differs from the insulation box 30 of the first embodiment in that, in addition to the inlet 30a for introducing the first group of yarn Y1, it also has an inlet 30c for introducing the second group of yarn Y2. The inlet 30c is formed on the upper half of the right side wall 38b of the box body 38, located between the inlet 30a and the outlet 30b, and serves as the entrance for the second group of yarn Y2. A guide roller 36A is disposed at the inlet 30c.

[0151] The guide roller 36A is configured to guide the second group of yarns Y2, which are separated from the first group of yarns Y1 by multiple yarns Y. In addition, in the spinning and stretching apparatus 3 of the first embodiment, two guide rollers 36 and 37 are provided to guide the second group of yarns Y2, but in the spinning and stretching apparatus 3A of the second embodiment, only one guide roller 36A is provided.

[0152] The guide roller 36A is configured as a rotatable roller having a rotation axis extending in the front-rear direction. Furthermore, the guide roller 36A is disposed in the insulation box 30A on the side wall 38b away from the plurality of guide rollers 31-33, and more specifically, at the inlet 30c provided on the side wall 38b. The guide roller 36A has an outer diameter larger than the thickness of the side wall 38b of the box body 38 of the insulation box 30A. Therefore, when viewed axially, the guide roller 36A protrudes from the side wall 38b of the box body 38 of the insulation box 30A toward both the outer and inner sides of the insulation box 30A. Additionally, the guide roller 36A is preferably configured as a drive roller driven by an electric motor (not shown), but it can also be configured as a driven roller rotated by friction of the second set of yarns Y2.

[0153] Unlike the spinning and stretching apparatus 3 of the first embodiment, the spinning and stretching apparatus 3A is equipped with a doubling auxiliary device 17. The doubling auxiliary device 17 is disposed inside the insulation box 30A, between the position where the yarn Y separates from the guide roller 35 on the downstream side in the yarn travel direction and the position where the yarn Y exits the insulation box 30A. Like the doubling apparatus 16, the doubling auxiliary device 17 is a winding device that injects compressed air to doubly the first group of yarns Y1 and the second group of yarns Y2. However, compared to the doubling apparatus 16, the injection pressure of the compressed air in the doubling auxiliary device 17 is set lower. Therefore, the degree to which the first group of yarns Y1 and the second group of yarns Y2 are doubly doubled by the doubling auxiliary device 17 is weaker than that of the doubling apparatus 16, and the doubling auxiliary device 17 serves to assist in the doubling process.

[0154] In the spinning and stretching apparatus 3A, the first group of yarn Y1 is introduced into the heat preservation box 30 via the feed roller 12 from the inlet 30a. Inside the heat preservation box 30, it is hooked onto the guide rollers 31-33 (which serve as preheating rollers), the guide rollers 34 and 35 (which serve as heat setting rollers), and the yarn doubling auxiliary device 17. Specifically, the first group of yarn Y1 is hooked onto the guide rollers 31, 32, 33, 34, 35, and the yarn doubling auxiliary device 17 in sequence. The first group of yarn Y1 is preheated to a temperature (above the glass transition point) that allows it to be stretched by the guide rollers 31-33 (which serve as preheating rollers). After preheating, the first group of yarn Y1 becomes a fully stretched yarn due to the difference in feeding speed between the guide rollers 33 and 34. Furthermore, the first group of yarn Y1 is heat-set by the guide rollers 34 and 35 while in a stretched state.

[0155] On the other hand, the second set of yarns Y2 is introduced into the interior of the insulation box 30A from the inlet 30c via the guide roller 36A, and hooked onto the guide rollers 34 and 35 and the yarn-coupling auxiliary device 37. Inside the insulation box 30A, the second set of yarns Y2 is guided from the guide roller 36A to the guide roller 34 adjacent to the right side wall 38b of the insulation box 30A. That is, the second set of yarns Y2 reaches the guide roller 34, which is a heat-setting roller, without passing through the guide rollers 31 to 33, which are preheating rollers. The second set of yarns Y2 is wound onto the guide rollers 34 and 35 without passing through the guide rollers 31 to 33, and therefore, it is heat-set by the guide rollers 34 and 35 in a partially oriented state.

[0156] The first group of yarns Y1 and the second group of yarns Y2, which converge on the guide roller 34, are combined by the yarn combining auxiliary device 37 to become a mixed yarn Y3. The mixed yarn Y3 is led out from the outlet 30b to the outside of the insulation box 30A and is wound by the winding device 4 via the feed rollers 13-15. Between the feed rollers 13 and 14, the mixed yarn Y3 is combined again by the yarn combining device 16.

[0157] [Wire-hanging unit]

[0158] Figure 25 This is a perspective view showing the wire-hanging unit 5A according to the second embodiment of the present invention. Figure 26 This is a front view showing the state of the insulation box 30A of the spinning and stretching device 3A in the mixed yarn manufacturing apparatus 1, where the yarn-hanging unit 5A is installed. Additionally, Figure 26 The diagram shows the insulated box 30 with its door 39 open. See below for reference. Figure 25 as well as Figure 26 The 5A unit for wire hanging is described.

[0159] In the mixed yarn manufacturing apparatus 1A, which manufactures mixed yarn Y3 by combining the first group of yarn Y1 and the second group of yarn Y2, a yarn hanging unit 5A is used during the yarn hanging operation of winding the second group of yarn Y2 onto the guide roller 36A and winding the first group of yarn Y1 onto a plurality of guide rollers 31 to 33 configured as preheating rollers.

[0160] The wire-hanging unit 5A is the same as the wire-hanging unit 5 of the first embodiment, and is configured to include a mounting portion 51 and a wire-hanging portion 52. However, compared with the wire-hanging unit 5 of the first embodiment, the wire-hanging unit 5A is configured to be shorter in the length direction. That is, the lengths of the mounting portion 51 and the wire-hanging portion 52 of the wire-hanging unit 5A are set to be shorter than the lengths of the mounting portion 51 and the wire-hanging portion 52 of the wire-hanging unit 5 of the first embodiment. Therefore, the wire-hanging unit 5A is configured to handle the wire-hanging operation of winding the second set of wire Y2 onto the guide roller 36A and winding the first set of wire Y1 onto the plurality of guide rollers 31 to 33, which serve as preheating rollers.

[0161] The mounting portion 51 of the wire-hanging unit 5A is configured to be detachably mounted to the main body 38 of the insulation box 30A. The mounting portion 51 has a base 51a and a plurality of hook portions 51b (two in the second embodiment). The base 51a is configured as an elongated, plate-like member extending linearly in the length direction. When the mounting portion 51 is mounted to the main body 38, the base 51a is positioned extending along the edge of the right side wall 38b of the main body 38. Furthermore, the base 51a of the wire-hanging unit 5A is shorter in the length direction than the base 51 of the wire-hanging unit 5 in the first embodiment. The length of the base 51 is, for example, set to correspond to the length from the inlet 30a of the insulation box 30A to the edge of the side wall 38b of the inlet 30c.

[0162] The hook portion 51b of the mounting portion 51 of the wire-hanging unit 5A is formed in the same manner as the hook portion 51b of the mounting portion 51 of the wire-hanging unit 5 in the first embodiment. The hook portion 51b is provided with a locking claw 51c that engages with a locking groove 38c on the side wall 38b of the body 38 of the insulation box 30A. When the mounting portion 51b is installed on the body 38, each hook portion 51b is inserted into each locking groove 38c provided on the side wall 38b of the body 38. Then, with each hook portion 51b inserted into each locking groove 38c, the mounting portion 51 is operated to shift its position downwards, thereby engaging the locking claw 51c on the front end side of each hook portion 51b with the stepped portion in each locking groove 38c. By engaging the locking claw 51c of the hook portion 51b with the stepped portion in the locking groove 38c, the mounting portion 51 is mounted on the body 38 and held in place on the body 38. Furthermore, in this embodiment, the mounting part 51 is installed on the box body 38 by engaging the hook 51b with the locking groove 38c. However, this is not necessary; the mounting part 51 can be configured to be easily installed and detached from the box body 38. For example, it is also possible to provide a groove different from the locking groove 38c on the side wall 38b of the box body 38, and to easily install and detach the mounting part 51 from the box body 38 by engaging the hook 51b with the groove provided on the side wall 38b.

[0163] The wire-hanging part 52 of the wire-hanging unit 5A is configured to hook the second set of wire Y2 when the mounting part 51 is installed on the housing body 38, and hooks the second set of wire Y2 during wire-hanging operations using the wire-hanging unit 5A. Furthermore, as... Figure 26 As shown, the wire-hanging part 52 is configured to extend along the edge of the side wall 38b of the box body 38, which is located away from the plurality of wire guide rollers 31-33 that serve as preheating rollers and on which the guide roller 36A is disposed, when the mounting part 51 is mounted on the box body 38. Furthermore, the wire-hanging part 52 is configured to extend along the edge of the side wall 38b of the box body 38 at a position that protrudes outward from the plurality of wire guide rollers 31-33 that serve as preheating rollers, and at a position that protrudes axially from the end faces of the plurality of wire guide rollers 31-33.

[0164] Specifically, the wire-hanging portion 52 is configured to have a rod-shaped portion 52a and a pair of feet 52b. The rod-shaped portion 52a is a rod-shaped portion that extends parallel to the length direction of the base 51a of the mounting portion 51. Furthermore, the rod-shaped portion 52a is configured to extend linearly in the vertical direction along the front edge of the side wall 38a of the box body 38, which is located away from the plurality of guide rollers 31-33 that serve as preheating rollers and on which guide rollers 36A are arranged, when the mounting portion 51 is mounted on the box body 38. In addition, the rod-shaped portion 52a is configured to extend in the vertical direction from a position corresponding to the height position of the lower half of the guide roller 34 to a position corresponding to the height position of the lower half of the guide roller 31, when the mounting portion 51 is mounted on the box body 38.

[0165] The pair of legs 52b of the wire-hanging portion 52 of the wire-hanging unit 5A are formed in the same manner as the pair of legs 52b of the wire-hanging portion 52 of the wire-hanging unit 5 in the first embodiment. Each pair of legs 52b is configured to protrude from the base 51a toward the side opposite to the side protruding from the hook portion 51b. Furthermore, each leg 52b is fixed to the base 51a at one end and integrally joined to the rod-shaped portion 52a at the other end to support the rod-shaped portion 52a. Thus, when the mounting portion 51 is mounted on the box body 38 of the insulated box 30A, the legs 52b protrude forward in the horizontal direction relative to the edge of the side wall 38b of the box body 38. Furthermore, the rod-shaped portion 52a is configured to extend parallel to the edge of the side wall 38b in the vertical direction at a position away from the edge of the side wall 38b of the box body 38 when the mounting portion 51 is mounted on the box body 38 of the insulated box 30.

[0166] According to the above configuration, the rod-shaped portion 52a of the wire-hanging unit 5A is configured to extend parallel to the length direction of the base 51a when separated from the base 51a of the mounting portion 51 by a distance equivalent to the length of the foot portion 52b. Furthermore, the rod-shaped portion 52a of the wire-hanging portion 52 is configured to extend in a straight line at the position where it is separated from the base 51a of the mounting portion 51 by the length of the foot portion 52b, thereby extending along the edge of the side wall 38b of the box body 38 at a position where it protrudes beyond the end faces of the multiple wire guide rollers 31 to 33 in the axial direction of the wire guide rollers 31 to 33 when the mounting portion 51 is mounted on the box body 38 of the insulation box 30.

[0167] [Wire hanging operation using a wire hanging unit]

[0168] Figures 27-33 This diagram illustrates the state of the wire-hanging operation using the wire-hanging unit 5A in the mixed-fiber manufacturing apparatus 1A. (Refer to...) Figures 26-33 The method of using the wire hanging unit 5A to perform the wire hanging operation in the mixed wire manufacturing apparatus 1A will be explained.

[0169] In manufacturing the blended yarn Y3, firstly, before manufacturing the blended yarn Y3, the multiple yarns Y spun from the spinning device 2 are divided into a first group of yarns Y1 and a second group of yarns Y2. The second group of yarns Y2 is wound onto the guide roller 36A, and the first group of yarns Y1 is wound onto multiple guide rollers 31-33. During the yarn winding operation, as follows... Figure 26 As shown, firstly, with the door 39 of the insulation box 30A open, a wire-hanging unit 5A is installed relative to the box body 38 of the insulation box 30A, at the edge of the side wall 38b of the box body 38, which is away from the plurality of wire guide rollers 31-33 and where the guide rollers 36A are arranged. At this time, the operator performing the wire-hanging operation (not shown) engages the hook 51b of the mounting part 51 with the locking groove 38c of the side wall 38b of the box body 38, thus installing the wire-hanging unit 5A onto the box body 38. Furthermore, with the wire-hanging unit 5A installed on the box body 38, the wire-hanging part 52 of the wire-hanging unit 5A is arranged to extend along the edge of the side wall 38b of the box body 38 at a position that protrudes from the end faces of the plurality of wire guide rollers 31-33 in the axial direction.

[0170] Figure 27 This diagram shows the state where the first group of yarn Y1 is wound around the feed roller 12 outside the insulation box 30, and the second group of yarn Y2 is wound around the guide roller 36A. (Refer to...) Figure 27 After the yarn hanging unit 5A is installed on the box body 38, the operator then uses the suction gun 100 to suck in multiple yarns Y spun from the spinning device 2, and divides the multiple yarns Y into the first group of yarns Y1 and the second group of yarns Y2.

[0171] When the operator separates multiple yarns Y into group 1 yarns Y1 and group 2 yarns Y2, the multiple yarns Y sucked in by the suction gun 100 are temporarily wound onto the guide roller 36A. Then, the operator holds the suction gun with one hand and a yarn separating tool (not shown) that can hook the yarns at the front end with the other hand, and separates the spun multiple yarns into group 1 yarns Y1 and group 2 yarns Y2 using the yarn separating tool held in the other hand. Next, with group 2 yarns Y2 wound on the guide roller 36A and stationary, the operator operates the yarn separating tool to wind group 1 yarns Y1 onto the feed roller 12. When group 2 yarns Y2 are wound on the guide roller 36A and group 1 yarns Y1 are wound on the feed roller 12, the operator puts down the yarn separating tool and holds the suction gun 100 with both hands. Then, the operator holds the suction gun 100 with both hands and manipulates its position so that the suction port 100a of the suction gun 100 moves between the guide roller 31 and the wire hanging part 52 of the wire hanging unit 5A. Thus, as... Figure 27As shown, the first set of yarn Y1, which is wound on the feeding roller 12, passes through the inlet 30a of the box body 38, and the second set of yarn Y2, which is wound on the guide roller 36A, passes through the rod-shaped part 52a in a state where it is hooked on the outer periphery of the rod-shaped part 52a of the yarn hanging part 52.

[0172] Figure 28 This diagram shows the state where the first group of yarn Y1 is wound on the first guide roller 31 in the direction of yarn travel. When the first group of yarn Y1 passes through the inlet 30a and the second group of yarn Y2 passes through the guide roller 36 and the yarn hanging part 52, the operator operates the position of the suction gun 100 with the suction port 100a inserted into the inside of the housing body 38. At this time, as... Figure 28 As shown, the operator uses both hands to operate the suction gun 100 so that the suction port 100a moves along the outer periphery of the guide roller 31. Figure 28 The yarn moves clockwise. As a result, the first group of yarns Y1 is wound onto the guide roller 31 along the yarn travel direction of the first group of yarns Y1. Furthermore, while the first group of yarns Y1 is wound onto the guide roller 31, the second group of yarns Y2, in the yarn channel from the guide roller 36 to the suction port 100a of the suction gun 100, is hooked onto the hanging part 52, which extends at a position protruding from the end face of the guide roller 31. Therefore, when the suction gun 100 is operated to wind the first group of yarns Y1 onto the guide roller 31, the yarn channel of the second group of yarns Y2 is maintained in a state where it protrudes from the end face of the guide roller 31. Thus, when the first group of yarns Y1 is wound onto the guide roller 31, it is possible to prevent the second group of yarns Y2 from being wound onto the guide roller 31 with the same yarn channel as the first group of yarns Y1.

[0173] Figure 29 This diagram shows the state where the first group of yarn Y1 is wound around the second guide roller 32 in the direction of yarn travel. When the first group of yarn Y1 has passed the first guide roller 31 in the direction of yarn travel, the operator further operates the position of the suction gun 100 while inserting the suction port 100a of the suction gun 100 into the inside of the housing body 38. At this time, as... Figure 29 As shown, the operator uses both hands to operate the suction gun 100 so that the suction port 100a moves along the outer periphery of the guide roller 32. Figure 29The yarn moves counterclockwise. As a result, the first group of yarns Y1 is wound onto the guide roller 32 along the yarn travel direction of the first group of yarns Y1. Furthermore, while the first group of yarns Y1 is wound onto the guide roller 32, the second group of yarns Y2, in the yarn channel from the guide roller 36 to the suction port 100a of the suction gun 100, is hooked onto the hanging part 52, which extends beyond the end face of the guide roller 32. Therefore, when the suction gun 100 is operated to wind the first group of yarns Y1 onto the guide roller 32, the yarn channel of the second group of yarns Y2 is maintained in a state where it protrudes beyond the end face of the guide roller 32. Thus, when the first group of yarns Y1 is wound onto the guide roller 32, it is possible to prevent the second group of yarns Y2 from being wound onto the guide roller 32 with the same yarn channel as the first group of yarns Y1.

[0174] Figure 30 This diagram shows the state where the first group of yarn Y1 is wound around the third guide roller 33 in the direction of yarn travel. When the first group of yarn Y1 has passed the second guide roller 32 in the direction of yarn travel, the operator further operates the position of the suction gun 100 while inserting the suction port 100a of the suction gun 100 into the inside of the housing body 38. At this time, as... Figure 30 As shown, the operator uses both hands to operate the suction gun 100 so that the suction port 100a moves along the outer periphery of the guide roller 33. Figure 30 The yarn moves clockwise. As a result, the first group of yarns Y1 is wound onto the guide roller 33 along the yarn travel direction of the first group of yarns Y1. Furthermore, while the first group of yarns Y1 is wound onto the guide roller 33, the second group of yarns Y2, in the yarn channel from the guide roller 36 to the suction port 100a of the suction gun 100, is hooked onto the hanging part 52, which extends beyond the end face of the guide roller 33. Therefore, when the suction gun 100 is operated to wind the first group of yarns Y1 onto the guide roller 33, the yarn channel of the second group of yarns Y2 is maintained in a state where it protrudes beyond the end face of the guide roller 33. Thus, when the first group of yarns Y1 is wound onto the guide roller 33, it is possible to prevent the second group of yarns Y2 from being wound onto the guide roller 33 with the same yarn channel as the first group of yarns Y1.

[0175] Figure 31 This diagram shows the state where the first group of yarns Y1 and the second group of yarns Y2 are wound around the fourth guide roller 34 in the direction of yarn travel of the first group of yarns Y1. When the first group of yarns Y1 has passed the third guide roller 33 in the direction of yarn travel, the operator further operates the position of the suction gun 100 while inserting the suction port 100a of the suction gun 100 into the inside of the housing body 38. At this time, as... Figure 31 As shown, the operator uses both hands to operate the suction gun 100 so that the suction port 100a moves along the outer periphery of the guide roller 34. Figure 31The wire-hanging portion 52 of the wire-hanging unit 5A, which extends from below to above along the edge of the side wall 38b of the box body 38, only extends to a position corresponding to the height of the lower half of the guide roller 34, and only extends to a position below the guide roller 36A. Therefore, when the suction gun 100 is operated so that the suction port 100a moves along the outer periphery of the guide roller 34... Figure 31 When the device moves counterclockwise, the second set of yarn Y2 hooked to the yarn-hanging part 52 of the yarn-hanging unit 5A detaches from the yarn-hanging part 52. Then, the second set of yarn Y2, detached from the yarn-hanging part 52 of the yarn-hanging unit 5A, becomes wound around the guide roller 36A and passes through the inlet 30c. After the second set of yarn Y2 detaches from the yarn-hanging part 52 and is wound around the guide roller 36A, when the suction gun 100 is further operated so that the suction inlet 100a moves along the outer periphery of the guide roller 34... Figure 31 When the middle and the north move counterclockwise, the first group of silk threads Y1 and the second group of silk threads Y2 are wound on the guide roller 34 along the silk travel direction of the first group of silk threads Y1 and the second group of silk threads Y2.

[0176] Figure 32 This diagram shows the state of the first group of yarns Y1 and the second group of yarns Y2 wound around the fifth guide roller 35 in the direction of yarn travel of the first group of yarns Y1. When the first group of yarns Y1 and the second group of yarns Y2 have passed through the guide roller 34, the operator further operates the position of the suction gun 100 while inserting the suction port 100a of the suction gun 100 into the inside of the housing body 38. At this time, as... Figure 32 As shown, the operator uses both hands to operate the suction gun 100 so that the suction port 100a moves along the outer periphery of the guide roller 35. Figure 32 The middle and north move in a clockwise direction. As a result, the first group of yarn Y1 and the second group of yarn Y2 are wound onto the guide roller 35 along the yarn travel direction of the first group of yarn Y1 and the second group of yarn Y2.

[0177] Figure 33 This diagram shows the state where the first group of yarn Y1 is wound on all guide rollers 31-35, and the second group of yarn Y2, wound on guide roller 36A, is also wound on a portion of guide rollers 34 and 35. When the first group of yarn Y1 passes through all guide rollers 31-35 and the second group of yarn Y2 passes through guide rollers 36A and guide rollers 34 and 35, the operator operates the suction gun 100 to allow the first yarn Y1 and the second yarn Y2 to pass through the yarn-coating auxiliary device 17. Furthermore, as... Figure 33As shown, the operator positions the suction gun 100 so that its suction port 100a passes through the discharge port 30b. This results in the mixed yarn Y3, after passing through the yarn-coating auxiliary device 17, being discharged from the discharge port 30b, thus ending the yarn loading operation. Subsequently, by adjusting the position of the suction gun to draw in the mixed yarn Y3 discharged from the discharge port 30b, the mixed yarn Y3 is wound onto the feed rollers 13-15 and then pulled towards the take-up device 4.

[0178] [Effects]

[0179] As explained above, according to the second embodiment of the present invention, when performing the yarn hanging operation in the mixed yarn manufacturing apparatus 1A during the manufacturing of the mixed yarn Y3, firstly, a yarn hanging unit 5A is installed at the edge of the side wall 38b of the main body 38 of the insulated box 30A, away from the plurality of guide rollers 31-33 and where guide rollers 36A are arranged. At this time, the yarn hanging part 52 of the yarn hanging unit 5A is arranged to extend along the edge of the side wall 38b of the main body 38 at a position that protrudes from the end faces of the plurality of guide rollers 31-33 in the axial direction. Then, in this state, the yarn hanging operation is performed. When the yarn hanging operation begins, the operator draws in the plurality of yarns Y spun from the spinning device 2 with the suction gun 100, and divides the plurality of yarns Y into a first group of yarns Y1 and a second group of yarns Y2. For the separated second group of yarn Y2, it is wound onto the guide roller 36A, which is located away from the multiple guide rollers 31-33 and is equipped with the yarn hanging unit 5A on the side wall 38b of the box body 38. Then, while holding the suction gun 100 that sucks in multiple yarns Y with both hands, the operator operates the position of the suction gun 100 to sequentially wind the first group of yarn Y1 relative to the multiple guide rollers 31-33. At this time, the second group of yarn Y2 wound onto the guide roller 36A and sucked into the suction gun is hooked in the yarn channel from the guide roller 36A to the suction port 100a of the suction gun 100, and is hooked onto the yarn hanging part 52 of the yarn hanging unit 5A, which is located at a position that protrudes outward from the multiple guide rollers 31-33 toward the box body 38 and at a position that protrudes axially from the end face of the guide rollers 31-33 along the edge of the side wall 38b of the box body 38. Therefore, when the operator uses both hands to hold the suction gun 100 and sequentially winds the first group of yarn Y1 relative to the multiple guide rollers 31-33, the second group of yarn Y2 is kept hooked to the hanging part 52 of the yarn hanging unit 5A. Thus, during the operation of winding the first group of yarn Y1 onto the multiple guide rollers 31-33, the yarn path of the second group of yarn Y2 is maintained in the following state: a portion of the yarn path of the second group of yarn Y2 located between the guide roller 36A and the suction gun 100 is wound to a position protruding outward from the multiple guide rollers 31-33 toward the box body 38, and also to a position protruding axially from the end faces of the guide rollers 31-33. Therefore, it is possible to prevent the second group of yarn Y2 from being wound onto the guide rollers 31-33 with the same yarn path as the first group of yarn Y1. Therefore, the operator can easily perform the wire-hanging operation by using both hands to operate the weighted suction gun 100, while maintaining the wire channel of the first group of wires Y1 and the wire channel of the second group of wires Y2 separate. Furthermore, because the wire-hanging operation can be performed easily, the operation time required for the wire-hanging operation can be significantly reduced.In addition, by significantly shortening the operation time of the wire hanging operation, the amount of wire sucked in by the suction gun 100 during the operation can be reduced, and the amount of wire re-spinning generated can be greatly reduced.

[0180] Therefore, according to the second embodiment of the present invention, it is possible to provide a wire-hanging unit 5A and a mixed-filament manufacturing apparatus having the wire-hanging unit 5A: the wire-hanging operation of sequentially winding the first group of filaments Y1 relative to a plurality of guide rollers 31 to 33 can be easily performed while operating the suction gun 100 with both hands, the operation time required for the wire-hanging operation can be greatly shortened, and the amount of filament sucked in by the suction gun 100 can be reduced, thereby greatly reducing the amount of filaments generated.

[0181] The embodiments and variations of the present invention have been described above. However, the present invention is not limited to the embodiments and variations described above. Various modifications and implementations can be made as long as they are within the scope of the claims.
