TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dyeing and winding method for dyeing cheese formed by winding a yarn around an outer periphery of a shaft member, and thereafter winding the cheese into a bobbin, and a shaft for winding.
[0002]
[Prior art]
For example, in the manufacturing process of a sewing thread, a twisted yarn is wound into soft cheese, and this is dyed with cheese. After dyeing, the yarn is wound into individual bobbins. During cheese dyeing, soft-wound cheese is axially compressed and then inserted into the spindle of a cheese dyeing machine in order to eliminate uneven dyeing due to yarn density unevenness caused by tension unevenness during cheese winding, etc. It is performed in multiple layers.
[0003]
In recent years, a press bobbin suitable for compressing soft-wound cheese in the axial direction together with a shaft member has been proposed and used. This type of press bobbin is made of plastic and has a plurality of through-holes formed in the cylinder, which is easily crushed when compressing cheese, and dye discharged from the spindle of the dyeing machine penetrates the through-hole of the cylinder after compression. It is configured to effectively penetrate the cheese through the medium (for example, see Patent Document 1).
[0004]
However, this type of press bobbin has a problem that it cannot be reused because it is compressed and crushed together with the yarn when the cheese is compressed, and must be discarded each time after dyeing. This is a problem that needs to be improved not only from the economic aspect of cost, but also from the social aspect of effective use of resources and waste disposal.

Is a cross-sectional view showing a state in which the winding shaft is attached to the inner cylindrical portion of the cheese, FIG. 5 is a schematic process diagram showing a winding process by a winding device, and FIG. 6 shows a winding process by another winding device. It is a schematic process drawing.
[0010]
First, the dyeing and winding method according to the first aspect of the present invention comprises a step of compressing cheese and extracting and dyeing a shaft member, and feeding the cheese to the inner cylindrical portion from which the shaft member of the cheese is extracted after the dyeing step. A step of inserting a shaft for use, attaching to a winding device, and winding the yarn wound around the cheese on a bobbin by a winding device.
[0011]
In the dyeing process, as shown in FIG. 1, the cheese 10 in which a thread is wound around the outer periphery of the shaft member 9 is compressed to extract the shaft member 9. As shown in the figure, the shaft member 9 can be easily removed by compressing only the wound portion 11 of the cheese 10 in the axial direction of the shaft member 9 with an appropriate tool. A broken line 10A in the figure represents a cheese shape before compression. The extracted shaft member 9 is repeatedly used for another cheese. The shaft member 9 is formed of a plastic or paper cylindrical body. In this example, a paper cylinder is used. As described above, the compression of the cheese 10 is performed in order to eliminate uneven dyeing due to a variation in yarn density due to a variation in tension at the time of winding the cheese and to perform uniform dyeing. In addition, the cheese 10 of the embodiment shown in the figure is one in which an elastic cover 13 is attached to a wound portion 11 of the cheese 10.
[0012]
As shown in FIG. 2, the cheese 10 from which the shaft member 9 has been removed is mounted in multiple stages by inserting a spindle 85 in a known cheese dyeing machine 80 into the inner cylindrical portion 12 thereof. The drawing shows a state in which the spindle 85 is raised. After the cheese 10 is mounted on the spindle 85, the cheese 85 is lowered into the dyeing tank 81. After the spindle 85 is lowered and the lid 82 is closed, the dye is discharged from the spindle 85 at a high pressure, and dyeing is performed from the inner periphery of the inner cylindrical portion 12 of the cheese 10. After the dyeing of the cheese 10 is completed, washing, dehydration and drying are sequentially performed by a known method.
[0013]
After the cheese 10 is dyed, a winding shaft 20 as shown in FIG. 3 is inserted into the inner cylindrical portion 12 of the cheese 10 and the yarn wound around the cheese 10 is mounted on the winding device. The bobbin is wound by a winding device. This bobbin winding process is for subdividing the yarn of the cheese 10 into individual yarn products, and the cheese 10 needs a shaft to be wound by the winding device. Therefore, the winding shaft 20 is inserted into the inner cylindrical portion 12 from which the shaft member 9 of the cheese 10 is removed, and is mounted on the winding device.
[0014]
As shown in FIGS. 3 and 4 and defined as the invention of claim 2, the winding shaft 20 has a first shaft having a cylindrical plate member 21, a tapered shaft portion 31, and a shaft core member 32. The member 30 includes a second shaft portion 40 having a tapered shaft portion 41 and an insertion fixing portion 42. The winding shaft 20 is mounted on the inner cylindrical portion 12 of the cheese 10 and is rotatably held by the winding device. The details will be described below.
[0015]
The tubular plate member 21 is inserted into the inner tubular portion 12 of the cheese 10, and is configured to be able to expand and contract in the inner circumferential direction in accordance with the inner circumferential diameter of the inner tubular portion 12 of the cheese 10. In this embodiment, the cylindrical plate member 21 is wound around a plastic plate member so that both ends 21e and 21e of the plastic plate member overlap each other so as to have a substantially "" shape in cross section. It is supposed to be. It is needless to say that the length of the tube plate member 21 in the tube direction is formed larger than the length of the inner tube portion 12 of the cheese 10.
[0016]
The first shaft member 30 is inserted from one side in the tube direction of the tube plate member 21 and has a tapered shaft portion 31 having a larger diameter toward the outside in the tube direction. And a shaft core member 32 protruding toward. The diameter of the tapered shaft portion 31 is formed to have a diameter smaller than a predetermined minimum inner diameter of the inner diameter 12 of the cheese 10 to a diameter larger than a predetermined maximum diameter. In addition, since the shaft core member 32 penetrates the second shaft portion 40 described below, the shaft core member 32 is formed to be sufficiently longer than the length of the inner cylindrical portion 12 of the cheese 10. In this example, the shaft core member 32 is formed by a screw rod 33.
[0017]
The second shaft portion 40 is inserted from the other side in the tube direction of the tube plate member 21, and has a tapered shaft portion 41 having a larger diameter toward the outside in the tube direction and the shaft core member 32 at the center of the tapered shaft portion 41. And an insertion fixing portion 42 for fixing the insertion at an arbitrary position. The tapered shaft portion 41 is, like the tapered shaft portion of the first shaft member 30 described above, from a diameter smaller than the planned minimum inner diameter of the inner diameter 12 of the cheese 10 to a diameter larger than the planned maximum diameter. It is formed to have. In this embodiment, the insertion fixing portion 42 has a through hole 43 formed at the center of the tapered shaft portion 41 and through which the shaft core member 32 (screw rod 33) is inserted, and the shaft core member 32 from the outside in the cylinder direction. It is composed of a fixing bolt 44 which is screwed to the screw portion of the (screw rod 33). Reference numeral 45 denotes a bolt seat. In addition, in addition to this example, as the insertion fixing portion 42, for example, an internal thread portion (not shown) is engraved on the second shaft portion 40 and directly screwed to the thread portion of the shaft core member 32. It may be.
[0018]
The operation of this winding shaft 20 will be described. As can be clearly understood from the cross-sectional view of FIG. 4, the cylindrical plate member 21 is inserted into the inner cylindrical portion 12 of the cheese 10 with a reduced diameter. The shaft core member 32 and the tapered shaft portion 31 of the first shaft member 30 are inserted into the inside of the cylinder 21 from one side in the cylinder direction such that the large diameter side of the tapered shaft portion 31 is outside the cylinder direction. On the other hand, the second shaft portion 40 is inserted from the other side in the tube direction inside the tube plate member 21 such that the large-diameter side of the tapered shaft portion 41 is outside in the tube direction, and the shaft core member 32 is inserted into the fixed portion. 42, here, it is inserted and fixed by the through hole 43 and the fixing bolt 44. At this time, the second shaft portion 40 is advanced inward in the cylinder direction, and the tapered shaft portion 31 of the first shaft member 30 and the tapered shaft portion 41 of the second shaft member 40 expand the cylindrical plate member 21 from the inside. The diameter is adjusted so that the cylindrical plate member 21 is securely pressed against the inner cylindrical portion 12 of the cheese 10. As a result, the cheese 10 and the winding shaft 20 are integrated, and an appropriate pressing force is applied to the yarn of the cheese 10 from the inner cylindrical portion 12 of the cheese 10, so that the yarn with a high elongation is also applied. The winding by the winding device can be reliably performed. In FIG. 4, reference numeral 35 denotes a bearing member, which is disposed on a receiving portion 51 of a later-described feeding device 50, and reference numeral 36 denotes a belt receiving portion on which a brake belt 54 of the later-described feeding device 50 is mounted. (See FIG. 5).

FIG. 5 is a schematic process diagram showing a winding process. As described above, the cheese 10 integrated with the winding shaft 20 is arranged and held by the receiving portions 51 and 52 of the winding device 50. The winding device 50 holds the winding shaft 20 rotatably. As in the embodiment, it is desirable that a bearing member is interposed between the winding shaft 20 and the receiving portions 51 and 52. The yarn S wound around the cheese 10 is wound around a bobbin 65 of a winding device 60 via a feed roller 55 and a tension member 56 as shown in FIG. The yarn S is wound around the bobbin 65 under tension. In the drawing, reference numeral 54 denotes a brake belt for applying a load to the rotation of the winding shaft 10, which is hung on a belt receiving portion 36 formed on the first shaft member 30.
