Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a device for connecting and continuously feeding out a plurality of filament bodies wound into coils.

[Conventional technology]

When a plurality of coiled filaments (hereinafter referred to as coils) are arranged and their ends are connected for continuous feeding, the position of the guide roller of the wire placed above is fixed and the coils are sequentially fed out from the guide roller. The methods of moving the wire guide rollers downward or above the coils require complicated equipment and manpower to move the coil or wire guide rollers, and may cause tangles due to wire twisting when switching coils. Utility Model Publication No. 51-8045 proposes a device that is easy to use and can continuously unwind coiled filaments more smoothly in consideration of these circumstances.

The device according to this publication, as shown in Figure 3,
A downwardly expanding hopper 11, 11' and a predetermined length of pipe 12, 1 connected to the upper part of this hopper.
A slit 14 connects the insides of the two downward wrapper tubes 13, 13', each of which is arranged vertically and parallel to each other, through which a filament consisting of a filament 2' passes. A common guide roller 15 is provided above the two wrapper tubes 13, 13' and the slit 14 and extends in the direction of the slit, and two coil-shaped rollers are connected at their respective ends so that they can be connected and unrolled. The filament body 2 is placed under two hoppers 11, 11' and the filament body 2 is fed out.

[The problem that the idea aims to solve]

However, in the above-mentioned conventional filament feeding device, when the filament wound in a coiled shape passes between the wrapper-shaped guide and the slit connected thereto, the filament comes into contact with each of the above-mentioned members. Corrects the curling of the striatum and the curl of the striatum when switching coils. During straightening, the surface of the filament is rubbed many times between the guide and the slit, and is easily damaged. Since the surface of the strip is processed with damage,
There was a problem with unfavorable quality.

This invention was made in consideration of the current state of the conventional wire-unwinding devices described above, and its object is to provide a wire-unwinding device which can unwind coiled wires arranged in two locations without damaging the surface of the wires, and which can automatically switch coils.

[Means to solve the problem]

Therefore, in this invention, as a means to solve the above problem, a plurality of coil-shaped filament bodies are arranged with their terminals connected to each other, and a filament body is arranged in parallel with the direction in which these filament bodies are arranged and above. A guide provided in at least two stages, upper and lower, forming a slit between guide members facing each other and having an arcuate cross section; The present invention adopted a structure of a filament feeding device that continuously feeds out the coiled filament, and consists of guide rollers of a predetermined length provided at different steps at intervals of .

[Effect]

The filament feeding device of this invention configured as described above connects the ends of each of the coiled filaments arranged in a row, and passes the filaments through the slit of the guide and the gap between the guide rollers. When switching the coil, the filament moves smoothly in the longitudinal direction within the slit or gap, thereby switching the coil. In this way, the coiled curl of the filament and the wire curl when switching the coils are corrected.

When the above-described curling or curling of the filament is to be corrected, the filament passes through a slit formed by mutually facing guide members each having an arcuate cross section. Therefore, the portion where the filament body contacts the guide member is not surface contact but line contact, and therefore wear and tear on the filament body surface is suppressed to a minimum.

〔Example〕

Embodiments of this invention will be described below with reference to the attached drawings.

As shown in FIG. 1, the filament feeding device of this embodiment includes two coiled filaments 1, 1',
It consists of a guide 5 consisting of guide members 3 and 4 provided in two upper and lower stages, and guide rollers 7 and 8 provided in different stages.

The coiled filament bodies 1, 1' connect the rear end of the filament body 1 on the side that is being fed out and the tip of the other filament body 1', and continuously form one continuous filament body. They are placed side by side on the floor so that the striatum can be drawn out.

The guide 5 is provided above and parallel to the direction in which the coiled filament bodies 1 and 1' are arranged, and has an arcuate cross section and faces each other, between which the coiled filament bodies are arranged. Guide members 3, 3 forming a slit 6 longer than the width; and the guide members 3,
The guide members 4, 4 are provided inside both ends of the slit 3, perpendicular to the longitudinal direction of the slit 6, and above or below the guide members 3, 3, respectively. Both ends of the guide members 3, 3 in the longitudinal direction forming the slit 6 may be closed so that the slit side has an arcuate cross-sectional shape without opening the slit.

The guide rollers 7 and 8 are provided above the upper guide 5 at different levels and parallel to the longitudinal direction of the guide 5, and are composed of two rollers that are longer than the width of the guide members 4 and 4.

The guide rollers 7, 8 and at least the slit-side surface of the guide member 3 of the guide 5, which come into contact with the filament 2 as it passes through, are finished with a surface treatment such as chrome plating to prevent the filament 2 from being damaged.

The striatal body feeding device of this embodiment configured as described above operates as follows.

As shown in FIG. 2, the filament 2 unwound from the coiled filament bodies 1, 1' passes through two tiered guides 5, 5 with slits formed therein, and passes between guide rollers 7, 8 at different levels. The wire is then fed out to equipment such as a twisting machine and an extruder for the next process.

While the filament body 2 travels as described above, the filament body 2 is corrected in the slits 6 of the two-stage guides 5, 5 and by the guide rollers 7, 8 at different levels, and the coils are switched. Sometimes the striatum 2 acts as a guide 5,
5 in the slit 6 and the guide roller 7 at a different level,
The coiled filament bodies 1 to 1' are automatically switched and fed out through the gap 8.

During such traveling and at the time of coil switching, the contact portion between the filament body 2 and the slit 6 of the guides 5, 5 is not a surface but a linear contact, so that the surface of the filament body 2 is not damaged. .

〔effect〕

As explained in detail above, the filament feeding device according to this invention includes a guide provided on the path through which the filament passes and is fed out, and a slit between the guides, which have arcuate cross sections and face each other. Since the guide member is formed from a guide member that is made of aluminum, there is no damage to the surface of the strand while the strand is running or when switching coils, and the coil can be switched automatically without any trouble caused by curls or tangles, resulting in high quality. stability and productivity can be improved.
