Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for winding an end portion of a spun glass fiber yarn around a winding collet at the start of spinning from a nozzle in a glass fiber winding machine.

When starting spinning on the glass fiber winder,
The operation of winding the yarn around the take-up collet (hereinafter simply referred to as the collet) has traditionally been a large-scale manual operation in which the yarn end is captured and tension is applied.
It was wrapped around the rotating collet. That is,
When spinning glass fibers, molten glass is spun into a large number of fibers from a bushing, passed through an oiling roller and a focusing roller, and wound onto a collect of a winder. The distance between the bushing and the winding machine is long, and the bushing is usually installed on the second floor of a building, and the winding machine is installed on the floor of the first floor.
Therefore, in order to wind the glass fiber yarn around the collect using the conventional method, there is a need for a worker located on the upper floor who is in charge of spinning the glass fiber from the bushing, and a worker located on the lower floor who is responsible for spinning the glass fiber from the bushing. The reality is that it is necessary to work collaboratively with the operator who catches the material and wraps it around the collet. However, such a conventional method requires manpower, requires skill, and puts a heavy burden on the worker, making it difficult to ensure the safety of the work. Furthermore, for example, in a turret-type automatic switching type glass fiber winding machine, various switching means are known for switching from a full collection to an empty collection, but a perfect one has not yet been provided. .

An object of the present invention is to provide a glass fiber yarn winding device which solves the above-mentioned conventional problems. It has a take-up device, a rotation mechanism for the auxiliary winder, and a reciprocating mechanism for moving the auxiliary winder forward and backward with respect to the collet, and the auxiliary winder has a plurality of pegs arranged concentrically with respect to the collet. and its free end protrudes facing the collet side, and the central circle is configured to have a larger diameter than the collet so that it partially enters a part of the outer periphery of the collet outside the winding and shifting range. It is something that Before winding the peg around the collet, the auxiliary winder is rotated to capture the yarn and temporarily wind it up to the required amount, and then the yarn is moved relative to the collet so that the free end of the peg is attached to the winding of the collet. The yarn is moved to the lower part of the peg outside of the arranging range, and the yarn wound around the outer circumference of the peg is transferred to the collet to facilitate winding. The present invention will be described below with reference to embodiments shown in the figures.

The embodiment shown in FIGS. 1 and 2 is a suitable device for winding the spun yarn 2 around the collet while pulling the end portion of the spun yarn 2 by a lower tension mechanism as described later at the start of spinning. The glass fiber yarn 2 spun from the upper bushing 1 is oiled via an oiling roller 3, and then wound onto a collect 6 of a lower glass fiber winder 5, where it is collected by a focusing roller 4. . 2a in FIG. 2 shows the criss-cross width of the glass fiber at the position where it is being normally wound around the collet 6, and 2b shows the width of the glass fiber at the stage where it is displaced by the front thread guide 11 winding around the collet 6, as will be explained below. Shows the glass fibers in A skein frame 7 is an example of an auxiliary winder which is a feature of the present invention, and is rotated by a motor 14. The skein frame 7 is disposed on the same axis of rotation as the collet 6, and can move back and forth over a distance l shown in the third figure. The reciprocating mechanism for this forward and backward movement is mainly composed of a cylinder 15 and its output rod 16, as will be explained below. That is, the motor 14 is supported on a movable base 14' that is placed on a fixed base 20 so as to be able to reciprocate left and right, and the right end of the movable base 14' is connected to the output rod 1 via a connecting frame 17.
It is connected at 6 ends. The movable table 14' also has a frame 19 that slides on the guide rod 18 of the fixed table 20. The reciprocating distance of the sling frame 7 (FIG. 3l) is set by limit switches 21 and 22 located at both ends of the guide rod 18. Further, each peg 8 for tensioning the yarn has its free end protruding toward the collet 6, and the skein frame 7 is constructed with the collet 6 side open. Furthermore, as shown in FIG. 3, each peg 8 is arranged on a concentric circle with a diameter larger than that of the collet, and at the position indicated by the solid line, the circle formed by the pegs surrounds the outer periphery of the tube K of the collet 6, and A portion of the reciprocating distance l overlaps the tube K of the collect 6 by a length S. Note that the skein frame 7 is rotated when necessary, as will be described later. Reference numeral 10 indicates a swaying mechanism for regular winding on the collet 6, and 11 is a thread guide which is connected to a cylinder and piston mechanism 13 via a connecting rod 12.
As a result, it reciprocates left and right in Fig. 2. Figure 2 shows the skein frame 7 with the thread guide 11 in the left standby position.
The figure shows a state in which the spun yarn 2 protruding toward the direction is displaced to the position 2b so as to be removed from the position of the collet 6.

To begin spinning the glass fibers and winding them around the collet, the glass fibers 2 spun from the bushing 1 must be
The end portion of the yarn is manually handled and guided to a tensioning device 9 below through an oiling roller 3 and a focusing roller 4. Known nip rollers 9a, 9 in the tensioning device 9
b grips and pulls the glass fiber 2.

At this time, the thread guide 11 moves to the front left as shown in Fig. 2 and temporarily holds the glass fiber 2 at the position 2b. Move the distance l in Figure 3.
In this case, the free end of the peg 8 overlaps the tube K or flange of the collect 6 by a distance S outside the swinging range. At the same time, it is rotated by the motor 14. As a result, the glass fibers 2 are captured between the pegs 8 of the skein frame 7 and wound around the outer circumference of the pegs. During this time, the collector 6 is also started. Thereafter, when the winding speed of the skein frame 7 reaches the rotational circumferential speed of the collet 6 after a while, the thread guide 11 is retracted from the left position to the right position 11' in FIG. .
As a result, the glass fiber is rolled up to the collet 6 by its own tension, as shown by the dotted line in FIG.
a Move toward the center position. At this time, the glass fiber 2 automatically engages with the thread guide for traversing, that is, the hook (not shown) of the traversing mechanism 10 of the winding machine 5, which has already started operation, and traversing begins.
The glass fiber comes into contact with the circumferential surface of the rotating collet and wraps around the collet. Therefore, from now on, the glass fiber 2 is wrapped around the collet 6 and wound up. The skein frame 7 returns to the standby position, and the remaining glass fibers wound around the skein frame 7 are removed manually or by mechanical means provided separately.

A series of operations such as advancing and retreating the skein frame 7 to the operating position, rotation, etc. are performed by a well-known program control mechanism similar to the operations of a conventional automatic winder, but a detailed explanation of this control mechanism will be omitted. According to this program control, the winding of the yarn end around the collet 6 can be done automatically without requiring manual labor as in the conventional method, thereby achieving the object of the present invention of reducing manual labor.

The present invention has been described above with respect to winding around a collet at the beginning of glass fiber spinning, but as mentioned above, the winding device of the present invention can also be used for continuous switching winding. That is, two of the collets 6 are pivotally supported by the turret T. By half a rotation of the turret, these two collets are alternately moved from the standby position to the operating position to effect continuous switching winding. In such a glass fiber winding machine, when switching, the glass fiber is temporarily wound around the skein frame 7,
The present invention can also be implemented in a device that transfers glass fibers from a skein frame to a new collet after a full collet and an empty collet have exchanged positions, thereby allowing efficient continuous switching winding. The auxiliary winder is not limited to the skein frame shown in the drawings, and various known winding frames can be used.

As detailed above, the present invention provides a skein frame with the collet side open on the same rotation axis as the collet, a skein winding mechanism, a skein winding mechanism, and a skein frame that is retracted from the collet. While the skein frame is rotating, the guide mechanism guides the yarn to the skein frame to effectively capture the yarn, transfers the yarn to the collet, and winds the yarn around the collet. It is effective for improving the performance of glass fiber winding machines and promoting automation.
