Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to a dyeing bobbin.

[Conventional technology and its problems]

Conventionally, in order to dye yarn in a package dyeing machine, as shown in Figs. 6 and 7, a small hole for discharging the dyeing solution is installed on the dyeing machine carrier b contained in the dyeing pot a. A spindle d... attached with c... is installed upright, and a large number of dyeing holes h are formed in the spindle d...
Thread winding bodies f... in which thread j is wound around a hollow truncated conical bobbin e having...... are stacked alternately with spacers g... which are approximately circular synthetic resin plates, and fixed in an externally fitted manner. I was going by. In other words, when the above conventional hollow truncated conical bobbins e... are stacked one above the other, the small diameter upper end of another bobbin e will fit deeply into the large diameter side opening of the bobbin e.
Spacer g as above between each bobbin e, e
It was necessary to intervene.

However, the dyeing solution k flowing near the bottom surface i of the spacer g is difficult to flow due to the influence of the weight of the upper part supported by the spacer g, and this causes it to come into contact with the spacer g. There was uneven dyeing of the thread j in the part. Furthermore, because of the spacers g, it becomes more labor-intensive to assemble the bobbins e in multiple stages in the vertical direction and to disassemble the dye solution.

An object of the present invention is to provide a dyeing bobbin that solves the above problems.

[Means for solving problems]

In order to solve the above-mentioned problems, the dyeing bobbin according to the present invention includes a hollow truncated conical bobbin body having a male threaded portion on the outer periphery of the large diameter side, and a female threaded portion screwed into the male threaded portion. and a diameter-reducing ring body having an abutment surface that abuts the small-diameter side upper end surface of another bobbin body located at a lower position; When the female threaded portion of the body is screwed into the assembled state, the outer circumferential surface of the bobbin body and the outer wall surface of the diameter reducing ring body are made into a continuous conical curved surface, and in the assembled state. In this case, the upper end surface of another bobbin main body on the small diameter side is brought into contact with the contact surface of the diameter reducing ring body, so that the bobbin bodies can be stacked one after another in the direction of the center line.

[Effect]

A hollow truncated conical dyeing bobbin is formed by assembling the diameter reducing ring body on the large diameter side of the bobbin body to form an integral body. These dyeing bobbins can be stacked one after another by bringing the small-diameter side upper end surface of another bobbin body located below into contact with the contact surface of the diameter-reducing ring body.

Even if the thread is wound up to the edge of the large diameter side of the outer peripheral surface of the diameter reducing ring body, the thread will not come off to the outside of the large diameter side, and when dyeing bobbins with thread wound in this way are stacked. , the lower end of the wound yarn comes into contact with the upper end of the yarn wound around another dyeing bobbin located below, and the dyeing solution is also applied to the contact area. It flows smoothly, preventing uneven dyeing.

〔Example〕

Hereinafter, the present invention will be explained in detail based on the illustrated embodiments.

In FIGS. 1, 2, and 3, reference numeral 1 denotes a spindle provided with a large number of dyeing solution discharge holes 2, which is installed upright above a dyeing machine carrier (not shown). 3... is a dyeing bobbin according to the present invention,
A hollow truncated conical bobbin body 6 having a male threaded portion 5 on the outer peripheral portion 4 on the large diameter side, and a smaller diameter bobbin body 6 located at a lower position and having a female threaded portion 7 screwed into the male threaded portion 5. It consists of a hollow truncated conical diameter-reducing ring body 10 having an abutment surface 8 that abuts the side upper end surface 8. A large number of dyeing holes 12 through which the dyeing liquid F discharged from the spindle 1 is discharged are formed in the outer circumferential surface 11 of the bobbin body 6. Therefore, the diameter reducing ring body 1 is attached to the male threaded portion 5 of the bobbin body 6.
In the state where the female screw part 7 of 0 is screwed and assembled,
The outer circumferential surface 11 of the bobbin body 6 and the outer wall surface 13 of the diameter-reducing ring body 10 are continuous conically curved surfaces. In the illustrated example, the diameter-reducing ring body 10 has a hollow truncated conical outer peripheral portion 14, and the outer peripheral surface 11 of the bobbin body 6 and the outer wall surface 13 of the diameter-reducing ring body 10 are aligned with the center line O. It is inclined at a certain angle. Also,
The diameter of the large-diameter side of the diameter-reducing ring body 10 is reduced to an inner flange shape,
A center hole 18 for inserting the spindle is formed in the center thereof. A fitting recess 15 is formed along the lower opening into which the upper end of another bobbin main body 6 at the lower position is fitted. This fitting recess 15
The abutting surface 9 is provided therein.

With the above-described configuration, the dyeing bobbin 3... has another bobbin body 6 on the contact surface 9 of the diameter reducing ring body 10.
The upper end surfaces 8 on the small diameter side of the sheets are brought into contact with each other so that they can be sequentially stacked in the direction of the center line O.

Next, thread 16 is applied to the outer peripheral surface of this dyeing bobbin 3...
By winding the thread, the thread-wound body 17... can be obtained. In this case, the thread 16 is
It is wound up to the large-diameter side edge of the outer wall surface 13 of the diameter-reduced ring body 10. And each thread winding body 17...
The upper end of another bobbin body 6 is fitted into the fitting recess 15 of the diameter reducing ring body 10, and the small diameter side upper end surface 8 of the bobbin body 6 is connected to the contact surface 9 of the diameter reducing ring body 10.
They can be brought into contact with each other, stacked one on top of the other, and fixed to the spindle 1 in an externally fitted manner. Further, a tightening nut 22 is provided on the male screw portion 21 at the upper end of the spindle 1, and by screwing this nut 22 forward and backward, the dyeing bobbin 3 of each yarn winding body 17 is attached via a pressing member 23.
...Press vertically with appropriate tightening force. Note that it is also preferable to transmit the pressing force of the pressing member 23 to the upper surface of the uppermost thread winding body 17 via a large-diameter circular plate (not shown). In this way, the thread-wrapped body 1
7... are stacked and fixed, the thread 16 at the lower end of each thread winding body 17... comes into contact with the thread 16 at the upper end of the stacked thread winding body 17 at the lower position. Therefore, the flow of the dyeing solution F at the boundary 20 between the threads 16, 16 is almost similar to the flow at other parts, and uneven dyeing does not occur.

Unlike the case of the above embodiment, it is also preferable that the contact surface 9 of the diameter-reducing ring body 10 is a flat lower end surface 19, as shown in FIG. Further, as shown in FIG. 5, it is desirable to form a fitting circumferential groove 24 in the lower end surface 19 of the diameter-reducing ring body 10, into which the upper end portion of another bobbin main body 6 at a lower position is fitted.

After the bobbin body 6 and diameter reducing ring body 10 are assembled to each other to form the dyeing bobbin 3..., so-called barbs are attached to the thread grooves to prevent the threaded parts 5 and 7 from loosening and coming off, since they will not be disassembled. It is also preferable.

[Effect of idea]

With the above configuration, the present invention has the following remarkable effects.

Although it is a hollow truncated conical bobbin, the diameter-reducing ring body 10 (omitting the conventional spacer)
The smaller diameter side upper end surface 8 of the bobbin body 6 of another dyeing bobbin is brought into contact with the contact surface 9 of the dyeing bobbin, and the dyeing bobbins can be stacked one after another.

The outer peripheral surface 11 of the bobbin body 6 and the diameter reducing ring body 1
It is possible to prevent a difference in level from occurring between the yarn and the outer wall surface 13 of the yarn, and to smoothly pull out the winding yarn that is running low, and to prevent the yarn from being damaged.

Once the yarn is wound around the dyeing bobbin, the dyeing bobbin and the yarn wound around it can be handled as one body until the yarn is pulled out after dyeing is completed.

Since the bobbin main body 6 has a tapered shape that expands only in one direction (large diameter side), injection molding is easy (a draft angle is naturally formed).
