Abstract

PURPOSE:To prevent generation of a kink by drawing out a linear substance drawn out from a bobbin with flier while guiding with a hood, and applying a load to the linear substance in the direction square to the drawing out direction at the rear side of the outlet. CONSTITUTION:Two bobbins 12a and 12b with a flier ring 14 respectively are installed rotatable to a supply stand 11, and the finish end and the start end of a linear substance wound on the both bobbins 12a and 12b are linked. The linear substance 13 is drawn out while being guided by a hood 15, and when it passes the outlet 15a of the hood, a downward load is applied to the linear substance 13 by a lever 6. That is, the lever 6 is made movable up and down by a bearing 7, and a load is applied in the direction square to the linear substance feeding direction. As a result, a hunting of the linear substance 13 is suppressed, and generation of a kink is prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for preventing kink in a linear body due to a flyer supply system in a wire manufacturing line or the like.

[Conventional technology]

In wire manufacturing lines, wire bodies are sometimes fed out using a flyer supply system.

In this system, for example, as shown in FIG. 3, a bobbin 2 and a flyer ring 4 are attached to a supply stand 1, and these are housed in a hood 5.

The linear body 3 wound around the bobbin 2 is unwound from the bobbin 2, guided to the hood 5, and pulled out from the narrowed end of the hood 5. When the linear body 3 is fed out using this method,
Although the linear body 3 is swung in the direction of the outer circumference of the bobbin 2 by the flyer ring 4, it collides with the hood 5, is prevented from flying around, and is guided to the outlet of the hood 5. Since the passage of the linear body 3 is narrowed at the exit of the hood 5, hunting (mainly vertical shaking) of the linear body 3 is suppressed;
Since the linear body 3 becomes free after exiting the exit of the hood 5, hunting occurs. In order to suppress this hunting and prevent the occurrence of kinks in the linear body, whisker-like protrusions 8 are provided on the flyer ring 4 to provide a catch on the linear body 3, as shown in FIG. 4, for example.

[Problem to be solved by the invention]

However, with the conventional method, it has not been possible to sufficiently prevent the occurrence of kinks in the linear bodies during fryer supply.

(Means and operations for solving the problem) The present invention provides a method for preventing kinking of a linear body using a flyer-the-bry method that solves the above-mentioned problems. The linear body is pulled out of the hood while being guided by the hood, and a load is applied to the linear body in a direction perpendicular to the drawing direction at the rear of the hood's exit I.

As mentioned in 17, if a load is applied to the linear body behind the hood outlet in a direction perpendicular to the direction in which it is pulled out, hunting of the linear body at the hood is suppressed, and kinks are prevented from occurring in the linear body. can be prevented.

〔Example〕

The present invention will be described in detail below based on an embodiment shown in one drawing.

FIGS. 1(a) and 1(b) show an embodiment of the present invention, in which bobbins 12a and 12b with two flyer rings 14 attached are housed in a spectacle-shaped hood 15. one bobbin], the winding start of 2a and the other bobbin 1
21) are connected, and after the linear body 13 of the bobbin 12a is pulled out, the linear body 1 of the bobbin 12b is connected.
3 withdrawals are made. 11 is a supply stand. The outlet 15a of the hood 15 has a horizontally elongated oval shape, and a linear body 13 is provided behind it, preferably near the outlet of the hood.
A lever 6 is installed to apply a downward load to the lever. This lever 6 is supported by a hair ring 7, and the linear body 1
3' - It is movable for downward movement.

Using this method, a PV conductor with a wall thickness of 0.10 mm was applied to a conductor made by twisting seven annealed single copper wires with an outer diameter of 0.127 mm.
A linear body that is likely to cause kinks, which is made by twisting two insulated wires coated with C composition, is guided by the hood and bowed out of the hood, and the linear body is drawn out at right angles to the direction in which the wire is pulled out behind the exit of the hood. Apply a load of 30g in the direction of linear velocity 20m/
When I pulled out this wire at min, it was 50.00
No kink occurred when the drawer was pulled out at 0 m. On the other hand, when this linear body was pulled out at the same speed without any load using the conventional method shown in FIG. 3, kinks occurred 50 times during the 50,000 m pullout.

In addition, when the wire was pulled out at the same speed without any load using the conventional method shown in Figure 4, 30 kinks occurred during the 50,000 m long wire feed.
Occurred twice.

Note that the method of applying a load to the linear body is not limited to the above method, and as shown in FIG. Any method is fine.

〔Effect of the invention〕

As explained above, according to the present invention, since a load is applied to the linear body in a direction perpendicular to the drawing direction of the linear body behind the outlet of the hood, it is possible to prevent kink from occurring during feeding of the linear body. It has the excellent effect of being able to
