At the end of take-up, after the guides 5 are retracted from the traveling zones of the strands 4, a yarn gathering guide 10 is projected out to make the strands 4 transfer to an adjacent reserve collet, while carrying out the removal of the cakes 9 and the installation of a new paper tube in the meantime.

Description

[Detailed Description of the Invention] [Field of Application in Industry A] The present invention is configured so that a plurality of cakes (strand-wound bodies) can be wound simultaneously by winding a plurality of strands in parallel. This invention relates to a glass fiber winding device.

[Prior art] Filament drawn from a large number (for example, several tens) of chips at the bottom of a bushing is divided and focused into multiple strands, and these are wound into a winding section (rotary winding section) of a winder. A device for rolling up a plurality of cakes in parallel at the same time is known (for example, Japanese Patent Laid-Open No. 56-28167,
(See especially Figure 1.3).

By the way, when winding the strand on this winding section, the strand is wound while being reciprocated (hereinafter sometimes referred to as traverse) in the axial direction of the winding section (for example, as disclosed in Japanese Patent Application Laid-Open No. 1983-1993). Figure 1 of 155157, Figure 1 of Japanese Patent Publication No. 53-44581). During this traverse movement of the strand, the reciprocating movement of the traverse member is synchronized to prevent the strand from coming off the traverse member (for example, a rotating spiral wire) once the traverse member has shifted to the end of the winding section. There is also known a device in which a strand is guided to a traverse member by a reciprocating guide member (see FIG. 2 of the above-mentioned Japanese Patent Publication No. 53-44581). In other words, when the traverse member shifts to the end of the winding section, a force is applied to the strand due to its tension that tends to move it toward the center of the winding section, but this force causes the strand to actually move away from the traverse member. It may slip off and move to the center. The above-mentioned special public service No. 53-4458
In the device No. 1, a guide member is provided above the traverse member, and the guide member is traversed so that the strand is always supplied to the traverse member while maintaining a posture in a direction substantially perpendicular to the axial direction of the winding section. The reciprocating movement is synchronized with the reciprocating movement of the members.

[Problems to be Solved by the Invention] The device disclosed in Japanese Patent Publication No. 53-44581 cannot simultaneously roll up a plurality of cakes in parallel.

In this case, it is conceivable to install a plurality of focusing members, guide members, and traverse members so that multiple cakes can be rolled up at the same time. Threading (winding the strand around the winding section) at the start is extremely troublesome and the work efficiency is low.

[Means for Solving the Problems] The glass fiber winding device of the present invention collects a large number of filaments pulled out from a bushing into a strand using a focusing member, and guides this strand using a guide member. The present invention relates to a device for winding a strand into a cake by guiding it to a traverse member and winding it around a winding section while traversing the strand.

In the glass fiber winding device of the present invention, a plurality of these converging members, guide members, and traverse members are each installed. This guide member is capable of moving forward and backward with respect to the strand running area. Further, a thread shifting device is provided for bringing these strands closer to the end of the winding section.

[Function] In the glass fiber winding device of the present invention, a large number of filaments pulled out from the bushing are divided and focused into a plurality of strands and are wound around a winding section, for example, a paper tube, via a guide member and a traverse member. , multiple cakes are rolled up in parallel at the same time. In this case, the strand is always supplied to the traverse member by the guide member while maintaining a posture substantially perpendicular to the axial direction of the winding section, so that the strand does not come off the traverse member.

In order to start winding, all the strands are brought to the end of the winding section by means of a thread shifting device. Note that at this time, the guide member is evacuated from the strand running area. The positions of the guide member and the traverse member in the axial direction of the winding section are set at the center of the winding member such as the paper tube. Also, the strand is wrapped around the end of the winding section,
The winding section is kept rotating.

After that, when the thread shifting by the thread shifting device is released, the strand is under tension due to being wound on the winding device, so the winding position is at the central winding position where the strand and the winding section are perpendicular to the wire direction. , at which point it engages the traverse member. Also, at this time, the guide member is advanced into the strand running area, and the strand is engaged with the guide member. As a result, the strand is guided by the guide member to the traverse member, and is then wound onto the winding section while traversing, thereby starting cake formation.

As described above, according to the apparatus of the present invention, a plurality of cakes can be rolled up simultaneously in parallel, and operations such as starting winding of the strands can be performed extremely easily.

[Actual 2i1 example] Examples will be described below with reference to the drawings.

FIG. 1 is a front view of an apparatus according to an embodiment of the present invention, and FIG. 2 is a right side view thereof. Reference numeral 1 denotes a bushing attached to the bottom of the glass melting furnace, and a number of chips (paths shown in the figure) are provided on the bottom surface of the bushing, from which a filament 1a is drawn out. An applicator 2 for applying a binding agent to the filament is arranged below the bushing 1, and a gathering ring 3 for collecting the filament is provided below the applicator 2. The filament 1a is collected into a strand 4 by the gathering 3, and wound around a paper tube 8 attached to a collet 7 via a strand guide 5 as a guide member and a spiral member 6 as a traverse member, and a cake 9 is formed. It is formed.

The strand guide 5 is rotated by a motor 11 as shown by the arrow A in FIG. There is. Note that, as shown in FIG. 3, the strand guide 5 is provided with a slit 5a in which the strand 4 engages.

A thread guide 10 is arranged above the strand guide 5, and the thread guide 10 is connected to an air cylinder 17.
This allows the strand 4 to protrude freely so as to be brought close to one end of the collet 7.

The spiral member 6 is attached to a rotating shaft 6a,
This rotation 116a is rotationally driven by the motor 14 of the machine box 6b. Note that the motor 14 is also used as a power source for driving the rotating shaft 6a to move forward and backward in the axial direction. The rotation shaft 6a causes the traverse member 6 itself to reciprocate by reciprocating in its axial direction. Reference numeral 6c is a spool for holding the rotating shaft 6a, and the strand guide connection support 18 is fixed to the distal end side of the spool 6c.

A sensor detection bar 12 for detecting the positions of the strand guide 5 and the spiral member 6 projects horizontally from the support 18, and the bar 12 is provided on the upper surface of the machine box 6b.
A center detection sensor 13 is fixed thereto, which is activated by the proximity of the center detection sensor 13. Further, the air cylinder 17 is connected to the bracket 1
It is fixed to the machine box 6b via 7a.

Machine box 6b is supported on machine base 15 via frame 15a. A collet drive motor 16 for rotating the collet 7 is installed on the upper surface of the machine base 15.

Next, a glass fiber winding operation using the above device will be explained.

As shown in FIG. 1.2, during the glass fiber winding operation in a steady state, the filament 1a is divided into two strands 4 by the gathering 3, and the paper is passed through the strand guide 5 and the spiral member 6, respectively. It is wound around the tube 8,
Form two cakes 9. At this time, the strand 4 is traversed in a relatively small width by the rotating spiral member 6, and is wound up onto the paper tube 8 while being traversed in a relatively wide range by the reciprocating movement of the traverse member 6. In this case, since the strand 4 is guided by the strand guide 5, the strand 4 runs in a direction substantially perpendicular to the axial direction of the collet 7, and the strand 4 is strongly restrained by the spiral member 6, ensuring that the strand 4 is Strand 4 can be traversed to
is prevented from coming off from the spiral member 6. In this way, a stable strand winding operation is performed during the winding of the cake 9.

Next, referring to FIGS. 3 to 5, the paper tube 8 of the strand
The winding process will be explained below.

That is, when starting winding of the strand 4, the strand guide 5 is raised up as shown in FIGS. 3 and 4, and the strand guide 5 is retracted from the running area of the strand 4. Then, the strand 4 is wound around the collet 7 with the thread guide 10 protruding and the strand 4 brought close to the end of the collet 7. After the winding is completed (in addition, when the winding is completed, the collet 7
(has been rotated), then the thread guide 10 is moved back as shown in FIG. Also, at this time, the strand guide 5
And the spiral member 6 is moved so as to be located at the center of the paper tube 8. The center positioning of the strand guide 5 and the spiral member 6 is performed using the center detection bar 1.
2 and the center detection sensor 13. That is,
When the spool 6C was shifted in the direction of retreating into the machine box 6b, the bar 12 came close to the sensor 13 as shown in FIG. 5, and the strand guide 5 and spiral member 6 moved to the center position of the paper tube 8. At this point, the motor 11 is driven by the signal from the sensor 13, and the strand guide 5 rotates so as to fall forward as shown in FIG. 2, and the strand 4 is caught in the slit 5a of the guide 5. Then, as described above, the spiral member 6
The strand 4 is wound around the paper tube 8 to form a cake 9 while performing a traverse motion by rotating and moving back and forth.

At the end of winding, the strand guide 5 is first rotated in the upright direction, contrary to the start of winding, and the strand guide 5 is retracted from the running area of the strand 4. Next, the thread guide 10 is projected, and the strand 4 is brought to the end of the collet 7 to complete spinning. When a new paper tube is attached to the collet 7 and cakes are formed continuously, the strand 4 is transferred to the adjacent spare collet (path shown), and the cake formed in the meantime is removed and a new paper tube is installed. After attaching the paper tube 8 of the strand 4 again in the same manner as above.
Start wrapping.

Although the spiral member 6 is employed as the traverse member in the above embodiment, it is clear that various traverse mechanisms other than the spiral member may be employed.

In the present invention, the guide 5 preferably has a shape in which the slit tip is widened and the slit rear end is closed, as shown in FIGS. 6 and 7. According to this guide:
The strand can be easily guided into the slit.

Since this strand guide is in constant contact with the strand, it is preferably made of a material with low friction such as graphite or ceramic. In addition, in the present invention, in order to more easily restrain the strands, it is preferable to mount a guide 21 made of metal, for example, whose tip is widened. Reference numeral 19 indicates a support member, and 20 indicates a mounting portion.

In the above embodiment, the strand guide is configured to move forward and backward from the strand running area by standing up and falling down.
It may be configured to move forward and backward as if sliding in the front and rear directions. Further, in the illustrated embodiment, two cakes are rolled up in parallel, but three or more cakes may be rolled up. The present invention may be applied to a turret type winder. Further, it may be applied to a type of winder in which the collet moves laterally.

[Effects] As described above, according to the apparatus of the present invention, a plurality of cakes can be formed simultaneously. In this case, threading can also be done very easily. Furthermore, in the apparatus of the present invention, after one cake is formed, it is also possible to form the next cake continuously without stopping the winding device.
