Description

[Detailed description of the invention] The present invention relates to a punch winding guide for punch winding used when winding yarn to form cheese or corn-shaped packages. (1) Waist punch winding forming part that can form a uniform and good punch winding during the attaching work;
The present invention relates to an improved punch winding guide comprising 2) a yarn transition section and (3) a haunch winding forming section.

Punch winding in thread-wound packages connects the outermost layer yarn end of one package to the innermost layer yarn end (punch winding end) of another package, making it possible to perform work for each package in the subsequent process. It has the advantage of being able to be used continuously without interruption, and is now indispensable in the formation of patchwork.

Generally, when winding yarn into a package in a friction/type winding machine or a spindle drive type winding machine, the yarn being sucked by a suction gun is first fixed to the machine base. As shown in Figure 3, unhook the waist punch winding guide 1.
′ is formed.

This waist punch winding 1' is wound a necessary number of times to fix the yarn end to the end on the bobbin 5.

Next, the yarn is transferred to a traverse section where a traverse movement is made by a traverse cam or a spring drum, and wound up into a package 6.

The intended punch winding is formed during the transition process of the yarn from the waist punch retaining section to the traverse section.

Note that the waist haunch retaining portion 1' is removed after the yarn 2' is fixed with the seal 4 before the package is packed.

Conventionally, when forming a punch winding using a punch winding guide consisting only of a waist punch winding forming section as shown in FIG. After forming the punch winding 1', the yarn was transferred to the traverse section while forming the punch winding 3' manually, which caused variations in the yarn transfer speed depending on the threading operator, and the transfer of the yarn from the waist punch winding forming section to the bobbin. The yarn transfer to the specified punch position in step 5 becomes uneven,
It was difficult to form a good punch roll, and insufficient punch rolls occurred frequently.

The present invention solves this drawback and provides a punch winding guide that can obtain good punch winding and form a punch winding that is easy to attach a seal for fixing the yarn end.

That is, the present invention provides a punch winding guide having a threading part for performing waist punch winding and punch winding, in which the threading part has a narrow groove shape, and the threading part has a curved narrow groove shape of a uniform width. and has a waist punch winding forming part, a yarn transition part, and a punch winding forming part in order from the deepest part of the threading part toward the yarn entrance/exit, and a waist punch winding forming part button and a punch winding forming part of the threading part. The punch winding guide is characterized in that the section has a linear shape substantially perpendicular to the bobbin axis, and the yarn transition section has a linear shape oblique to the bobbin axis.

The explanation will be given below according to the drawings. Fig. 2 is a simplified diagram showing a specific example of the punch winding guide of the present invention. Waist haunch winding forming part 1, yarn transition part 2, and punch winding forming part 3 in order from the deepest part of the hanging part toward the yarn entrance/exit.
It consists of

To use the punch winding guide of the present invention, when the thread is hooked onto the punch winding guide and the thread is started to be wound onto the bobbin, the waist punch winding forming section 1 forms a waist punch winding 1' as shown in FIG. When the thread is removed from the thread hooking part, a punch winding 2' to which a sticker 4 can be easily attached is formed by the thread transition part 2 provided in a direction diagonal to the bobbin axis.

Furthermore, when the thread is removed from the threading section, a punch winding 3' is formed by the punch winding forming section 3.

In this way, the thread hooking part of the punch winding guide connects the waist punch winding forming part 1 and the punch winding forming part 3, which are linearly shaped almost perpendicular to the bobbin axis, and the thread is transferred to the thread which is linearly shaped obliquely to the bobbin axis. By removing the yarn from the threading section, waist punch winding and punch winding can be formed, respectively, and the yarn can then be transferred to the traverse section.

In addition, since the yarn is transferred along the punch winding guide, it is possible to prevent the yarn transfer speed from becoming extremely fast, and it is possible to form a punch winding with no shortage of turns, and also to make it uniform. The curved narrow groove of a wide width allows the waist punch winding section, the yarn transition section and the punch winding section to accurately guide the yarn onto the end of the bobbin 5.

By appropriately changing the angle and length of the yarn transition section 2 or the angle and length of the punch winding forming section 3, the yarn winding interval in the seal pasting section, the number of punch windings, and the winding density can be changed as appropriate. can do.

Normally, the length of the punch winding forming portion 3 is preferably about 15 mm from the viewpoint of thread attachment workability.

As described above, when a thread winding package is formed using the punch winding guide of the present invention, there is no variation in the number of windings, there is no defect of insufficient winding, the punch winding position is accurate, good punch winding can be obtained, and yarn transfer. Since the part and punch winding part are clearly defined, it is easy to attach the seal for fixing the yarn end, which has a great effect on work efficiency in the subsequent process.
