The spinning draft apparatus 1 mainly includes a spinning device 3, a spinning draft device 4, a yarn lowering device 5, a yarn threading device 6, and a control device 7. The spinning device 3, a part of the structure of the spinning draft device 4, and the yarn lowering device 5 are disposed on the 2 nd layer, and the remaining structure of the spinning draft device 4 and the spinning device 6 are disposed on the 1 st layer. In addition, the filament lowering device 5 can move freely in 2 layers. Therefore, the arrangement of the wire lowering device 5 of fig. 1 is merely an example. The control device 7 controls the overall operation of the spinning and drawing device 1. Specifically, the control device 7 controls the operation of the spinning draft device 4 or issues a spinning command to the spinning head device 6.

In the spinning and drawing device 1 of the present embodiment, a plurality of spinning devices 3 and a plurality of spinning and drawing devices 4 are arranged in a direction perpendicular to the sheet of fig. 1. In the partition floor 2, a plurality of openings 2a through which the plurality of yarns Y spun from the respective spinning devices 3 arranged on the 2 nd layer can pass are formed in the direction perpendicular to the sheet of fig. 1. In order to prevent the wire from wobbling, a tubular cover member 8 protruding downward from the partition floor 2 is provided below the peripheral portion of each opening 2 a. In addition, in order to prevent the wire lowering device 5 and the like from falling from the 2 nd floor, a tubular drop-preventing wall 9 protruding upward from the partition floor 2 is provided above the peripheral portion of each opening 2 a.

For convenience of explanation, the up-down direction of fig. 1 is defined as the up-down direction of the spinning draft device 1, the left-right direction of fig. 1 is defined as the front-back direction of the spinning draft device 1, and the vertical direction of the paper surface of fig. 1 is defined as the left-right direction of the spinning draft device 1.

(spinning apparatus)

The spinning device 3 is provided on the 2 nd layer and has a structure in which a spinning pack 10 having a spinneret 10a is attached. A plurality of synthetic filaments Y can be spun from the spinneret 10a by extruding the molten polymer in a high temperature state supplied from a polymer supply device, not shown, constituted by a gear pump or the like from the spinneret 10 a.

(spinning traction device)

The spinning traction device 4 draws the plurality of yarns Y spun from the spinning device 3, respectively, and winds the drawn yarns onto the plurality of bobbins B, respectively, to form a plurality of packages P. The spinning and drawing device 4 includes a cooling unit 11, a finish guide 12, a yarn regulating guide 13, a yarn holding unit 14, a drawing unit 15, a winding device 16, and the like.

By the reciprocation of each traverse guide 23a, the yarn Y is wound around the bobbin B while traversing around the fulcrum guide 25, thereby forming a package P. The contact roller 24 is in contact with the packages P formed on the upper bobbin holder 22, and applies contact pressure to each of the packages P.

(filament lowering device)

Next, the wire lowering device 5 will be explained. Fig. 2 is a perspective view of the wire lowering device 5, fig. 3 is a schematic view showing the wire lowering device 5 after being positioned, fig. 4 is a schematic view showing the wire lowering device 5 in a state where the guide member is lowered, fig. 5 is a schematic view showing the wire lowering device 5 in a state where the wire lowering member is lowered, and fig. 6 is a sectional view of VI-VI of fig. 5. The yarn lowering device 5 is for lowering the plurality of yarns Y spun from the spinning device 3 toward the 1 st layer at the time of yarn drawing before the start of production of the package P.

The yarn feeding device 5 includes a carriage body 30, a yarn feeding member 31, a guide member 32, a suction gun (サクションガン)33, and the like. The wire lowering device 5 is configured by mounting various components on the carriage main body 30, and the wheels 34 and the operation unit 35 are mounted on the carriage main body 30. Further, the operator can move the wire lowering device 5 freely on the partition floor 2 by operating the operation portion 35.

The wire lowering member 31 includes a support portion 31a extending in the vertical direction and a holding portion 31b attached to the lower end portion of the support portion 31 a. The holding portion 31b is formed with 2 slit-shaped hooking portions 31c which are opened downward and can hook the plurality of threads Y. The 2 hooking portions 31c are disposed apart from each other in the horizontal direction with the supporting portion 31a interposed therebetween. As will be described later, the yarn lowering member 31 is lowered while the plurality of yarns Y are hooked and held on the 2 hooking portions 31c, and the plurality of yarns Y can be lowered toward the 1 st layer.

The wire (ワイヤー)36 is connected to the upper end of the wire lowering member 31. Further, a 1 st reel 38 for winding the wire 36 is rotatably attached to a plate-like support member 37 standing from the floor surface of the carriage body 30. The 1 st reel 38 is rotationally driven by a 1 st motor 39. A pin member 40 for hooking the wire 36 is attached to the support member 37, and a path of the wire 36 when the wire lowering member 31 is raised and lowered is defined by the pin member 40. By rotating the 1 st reel 38 in the direction of pulling out the wire 36, the wire lowering member 31 is lowered below the pin member 40. Further, the wire lowering member 31 is raised by rotating the 1 st reel 38 in the direction of winding the wire 36.

The guide member 32 guides the wire lowering member 31 in the vertical direction when the wire lowering member 31 is lifted. The guide member 32 is formed of a chain-like cable drag chain (registered trademark) in which a plurality of minute elements 32a are rotatably connected to each other, and has flexibility in winding. As shown in fig. 6, the microscopic element 32a of the guide member 32 has an コ -shaped cross-sectional shape with a right side (side facing the yarn descending member 31) open. On the other hand, a plurality of engaging portions 31d (see fig. 3 and the like) are formed in a vertical direction on the back surface (the surface on the side facing the guide member 32) of the support portion 31a of the wire lowering member 31. In a state where the engaging portion 31d of the wire lowering member 31 is engaged with the micro element 32a of the guide member 32, the internal space of the micro element 32a is moved in the vertical direction, whereby the wire lowering member 31 can be raised and lowered while being guided by the guide member 32.

The 2 nd reel 41 for winding the guide member 32 is rotatably attached to the support member 37. The 2 nd reel 41 is rotationally driven by a 2 nd motor 42. Further, a pin member 43 for hooking the guide member 32 is attached to the support member 37, and a path of the guide member 32 when the guide member 32 is lifted and lowered is defined by the pin member 43. By rotating the 2 nd spool 41 in the direction of pulling out the guide member 32, the guide member 32 is lowered below the pin member 43. Further, the guide member 32 is raised by rotating the 2 nd reel 41 in the direction of winding the guide member 32. The 1 st motor 39 and the 2 nd motor 42 are supplied with electric power from a battery, not shown, mounted on the carriage main body 30.

In the portion where the guide member 32 is bent in contact with the pin member 43, the internal space of the micro element 32a is opened upward, and the engaging portion 31d of the wire lowering member 31 can be moved into and out of the internal space of the micro element 32 a. In fig. 2, the illustration of the microscopic elements 32a is omitted in the vicinity of the pin member 43 in order to show the pin member 43.

As shown in fig. 3 to 5, in order to position the guide member 32, the positioning mechanism is constituted by an engaging member 44 provided at the lower end portion of the guide member 32 and a positioning member 26 attached to the lower end portion of the inner wall of the cover member 8. As shown in fig. 6, the engaging member 44 has a shape capable of engaging with the positioning member 26 from above. Thus, the guide member 32 is lowered to engage the engagement member 44 with the positioning member 26, thereby temporarily fixing the guide member 32.

When the yarn is dropped by the yarn dropping device 5, first, the yarn dropping device 5 is disposed in the vicinity of the opening 2a formed below the spinning device 3 to be the target. At this time, as shown in fig. 3, the wire lowering device 5 is disposed so that the contact portion 30a formed at the front end portion of the carriage body 30 of the wire lowering device 5 contacts the drop preventing wall 9 formed around the opening 2 a. Thereby, the filament lowering device 5 is positioned in the left-right direction of fig. 3. In the present embodiment, a mark is provided at an appropriate position of the partition floor panel 2, and this mark serves as an aid in positioning in the direction perpendicular to the paper surface of fig. 3. That is, the positioning of the wire lowering device 5 is possible by bringing the contact portion 30a of the carriage body 30 into contact with the drop prevention wall 9 and moving the wire lowering device 5 to the position indicated by the mark.

As shown in fig. 4, after the positioning of the yarn lowering device 5 is completed, the guide member 32 is lowered. As described above, by appropriately positioning the wire lowering device 5, when the guide member 32 is lowered, the engagement member 44 attached to the lower end portion of the guide member 32 can be smoothly engaged with the positioning member 26, and the guide member 32 can be fixed. Next, as shown in fig. 5, the wire lowering member 31 is lowered along the guide member 32, whereby the holding portion 31b is positioned below the lower end of the cover member 8. This enables the plurality of threads Y (not shown in fig. 5) held by the holding portion 31b to be delivered to the thread feeding device 6 and the thread holding portion 14. Details of a series of operations will be described later.

The suction gun 33 is a member for sucking and holding the plurality of yarns Y spun from the spinning device 3 during the yarn lowering. The suction gun 33 of the present embodiment is fixed to the carriage body 30, but may be detachable from the carriage body 30. A suction hose 33a is connected to the suction gun 33. On the other hand, a suction adapter 2b connected to a suction source, not shown, provided in the spinning draft device 1 is provided in the vicinity of each opening 2 a. Further, by connecting the suction hose 33a of the suction gun 33 to the suction adapter 2b, a suction force can be generated at the suction port at the tip of the suction gun 33. The plurality of yarns Y sucked by the suction gun 33 are passed through a suction hose 33b different from the suction hose 33a and discarded to a waste yarn box, not shown.

(spinning-in device)

The piecing device 6 is a piecing robot controlled by a program. The threading device 6 is configured to be movable in the left-right direction (vertical direction to the paper surface of fig. 1), and includes a threading arm 6a having an articulated portion so as to be movable in the three-dimensional direction. Although not shown, a cutter for cutting the yarn Y and a suction unit for sucking the yarn Y cut by the cutter are provided at the tip of the yarn feeding arm 6 a. When a yarn threading command is received from the control device 7 from one of the plurality of yarn drawing devices 4 arranged in the left-right direction, the yarn threading device 6 moves to a position in front of the yarn drawing device 4 and performs yarn threading to the 2

godet rollers

19 and 20 of the drawing section 15 and the winding device 16.

(Process for lowering silks and growing heads)

Finally, the flow of operations such as lowering and threading when the spinning draft device 4 starts the production of the yarn Y will be described with reference to fig. 7 to 11. Fig. 7 is a diagram showing the spinning and drawing device 1 before the guide member 32 is lowered, fig. 8 is a diagram showing the spinning and drawing device 1 in a state where the guide member 32 is lowered, fig. 9 is a diagram showing the spinning and drawing device 1 immediately before the yarn lowering member 31 is lowered, fig. 10 is a diagram showing the spinning and drawing device 1 in a state where the yarn lowering member 31 is lowered, and fig. 11 is a diagram showing the spinning and drawing device 1 in the course of spinning by the spinning device 6.

When a yarn is fed to a spinning draft device 4, the operator moves the yarn lowering device 5 to the spinning draft device 4 as shown in fig. 3 and 7. As described above, the yarn feeding device 5 is positioned at an appropriate position so that the engaging member 44 engages with the positioning member 26 when the guide member 32 is lowered later. In the positioned yarn lowering device 5, the 2 hooking portions 31c of the yarn lowering member 31 are arranged in the front-rear direction.

Next, the operator causes the suction gun 33 to suck and hold the plurality of yarns Y spun from the spinning device 3, and then hooks the plurality of yarns Y sucked by the suction gun 33 to the finish guide 12 and the yarn restricting guide 13. Before and after this, the control device 7 immediately gives a spinning-in command to the spinning-in device 6 to move the spinning-in device 6 to the position of the spinning draft device 4.

Next, as shown in fig. 4 and 8, the operator drives the 2 nd motor 42 to pull out the guide member 32 from the 2 nd reel 41 and lower the guide member 32. As a result, the guide member 32 is further lowered through the opening 2a, and finally, the engaging member 44 is lowered to a position where it engages with the positioning member 26. By engaging the engaging member 44 with the positioning member 26, the guide member 32 can be prevented from wobbling, and the wire lowering member 31 can be stably raised and lowered along the guide member 32.

Next, as shown in fig. 9, the operator hooks the plurality of threads Y with the threading tool T and moves the plurality of threads Y so that the threads Y between the suction gun 33 and the threading tool T are positioned directly below the holding portion 31b of the thread lowering member 31. More specifically, when the yarn lowering member 31 is continuously lowered, the yarn passage is adjusted so that the yarn Y between the suction gun 33 and the threading tool T enters the 2 hooking portions 31 c.

Next, as shown in fig. 5 and 10, the operator drives the 1 st motor 39 to pull out the wire 36 from the 1 st reel 38, thereby lowering the wire lowering member 31. At this time, the plurality of threads Y are hooked on the 2 hooking portions 31c of the thread lowering member 31, and the plurality of threads Y are held by the holding portions 31 b. In the present embodiment, since the yarn lowering device 5 is positioned such that the 2 hooking portions 31c are arranged in the front-rear direction, when the yarn lowering member 31 is lowered, as shown in fig. 10, the yarn passage from the yarn restricting guide 13 to the suction gun 33 via the holding portion 31b of the yarn lowering device 5 has a V-shape that opens in the front-rear direction.

When the yarn lowering member 31 is lowered to the lowermost position, the yarn threading device 6 brings the yarn threading arm 6a into contact with the plurality of yarns Ya between the yarn restricting guide 13 and the holding portion 31b of the yarn lowering device 5 from the front side of the spinning draft device 4. Further, the plurality of filaments Ya are cut and held by suction. At this time, as described above, the yarn Ya on the upstream side of the holding portion 31b and the yarn Yb on the downstream side of the holding portion 31b are separated in the front-rear direction, and thus the yarn threading device 6 can be prevented from cutting and sucking and holding the plurality of yarns Yb and the plurality of yarns Ya in different yarn running directions together.

When the threading device 6 sucks and holds the plurality of yarns Y by the threading arm 6a, the threading arm 6a is operated to hook the plurality of yarns Y to the

godet rollers

19 and 20 of the drawing section 15 in order as shown in fig. 11. After the end of the delivery of the yarn Y to the yarn threading device 6, the operator sequentially raises the yarn lowering member 31 and the guide member 32 and returns them to the carriage main body 30.

[ Effect ]

As described above, the filament lowering device 5 of the present embodiment includes: a carriage body 30 configured to be movable on the 2 nd layer (upper layer), and a yarn descending member 31 provided on the carriage body 30 and capable of descending to the 1 st layer (lower layer) while holding the plurality of yarns Y spun from the spinning device 3. With this configuration, since the wire lowering member 31 is provided on the carriage body 30 configured to be movable on the 2 nd floor, the wire can be lowered at an appropriate position by moving the carriage body 30. Therefore, even when a plurality of the spinning draft devices 4 are arranged, the yarn can be dropped at each spinning draft device 4 by moving the carriage body 30, and there is no need to provide a dedicated device for each spinning draft device 4, so that the facility cost including the maintenance cost can be suppressed.

In the present embodiment, the wire lowering member 31 is provided with a plurality of hooking portions 31c which are separated from each other in a direction (front-rear direction) intersecting the vertical direction and which can hook the plurality of wires Y.
