Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is an improvement of a glass fiber spinning winding device in which a large number of long glass fibers spun from a spinning bushing are bundled into a strand, and the strand is draft-wound onto a winding collet. In particular, at the start of spinning winding mainly when the spinning strand is broken, the strand is accurately captured and auxiliary winding is performed, and the auxiliary winding speed is adjusted to the predetermined rotational speed of the winding collet. At that point, the strand is transferred to a winding collet so that a glass fiber strand of a predetermined diameter can be wound.

Long glass fibers are usually made by spinning a large number of filaments from a bushing equipped with many nozzles, applying a sizing agent to the filaments, and converging them into one or more filaments to form a strand that rotates several thousand times per minute. By winding at a constant speed of 1,500 to 5,000 m/min, a predetermined draft is applied to the circumferential surface of the collet.
Glass filaments with a constant diameter are manufactured by quantitative winding of several hundred to several thousand strands.

Therefore, an intermittent operation is performed in which the full bobbin on the collet that has been wound in a fixed amount is removed from the collet, and then an empty bobbin made of paper or film is fitted and winding is performed. Since the glass filament flows out without interruption, two or three collects are alternately moved to the winding position, the full bobbin removal position, and the empty bobbin insertion position to correspond to the intermittent winding of the collects mentioned above. It is installed on a rotating stand or a reciprocating stand so as to allow for rapid switching and winding.In addition, it is possible to increase the winding speed from a stopped state before and after the constant speed winding speed, and to decelerate the winding part from a constant speed winding state. Various means have already been proposed and implemented to eliminate the large diameter filament portion that occurs in the waist strand.

As a means of eliminating the above-mentioned waist strands, it is possible to provide an auxiliary winding section on the free end side of the winding collet, or to provide an auxiliary winding machine separate from the collet to separate it from the regular winding section. However, the former method requires the operation of cutting and removing the waist strand when removing the full bobbin from the collet, prolonging the collet changeover time, and, in addition, both the initial winding and wire breakage occur. Since winding is done manually by the operator, there are problems with reliability and safety.

The present invention solves the conventional problems by automating the conventional winding operation of the waist strand portion without manual intervention, thereby making it possible to reliably wind the waist strand onto the auxiliary winding frame. .

That is, the glass fiber spinning take-up device of the present invention applies a sizing agent to a large number of glass filaments spun from an upper spinning bushing, and collects the strands. A guide rod protrudes to guide the traverse out of the operating range of the traverse device, and a guide rod of the take-up collet so as to tension-transfer the strand guided by the protruding guide rod downward through the front surface of the free end of the take-up collet. A tension roller is provided below the free end, and a plurality of pegs are arranged on the circumference with a larger diameter than the take-up collet, which rotates in line with the rotation axis of the take-up collet, facing the front surface of the free end of the take-up collet. The auxiliary winding skein frame is provided so as to be able to move forward and backward in the axial direction thereof, and by doing so, the auxiliary winding skein frame advances from the retreating standby position to the strand tensioning and transferring path, When the auxiliary winding rotation is started, the strand is reliably caught and wound on the skein frame, and the winding speed is increased until it almost matches the speed of the winding collet, which is already rotating at a predetermined rotation speed. The strand, which is being wound onto the auxiliary take-up skein frame, is moved to the take-up collect surface by rapidly retracting the thread guide rod in the protruding position that was guiding the strand beyond the operating range of the traverse device. At this point, the rotation of the auxiliary take-up skein is rapidly stopped by braking, and the end of the strand wound on the take-up collet is cut off by the tensile force, and the auxiliary take-up skein moves back. A predetermined layer formation and winding are performed by moving the traverse device itself in the axial direction while being swayed by the traverse device. The strand wound on the auxiliary winding skein is pushed out from the surface of the skein frame and removed.

This is different from the conventional method in that two or three winding collets are mounted on a rotating frame or a reciprocating frame, and by moving the frame, each is placed in the winding position, the full bobbin removal position, and the empty bobbin insertion position. There is no place.

When the take-up collet reaches a full tube state, the auxiliary take-up skein frame advances from the standby position, and when it reaches approximately the same rotational speed as the collet, the thread guiding rod protrudes to a specific position.
The strand transfer path is moved from the winding collet surface to the rotating auxiliary winding skein frame by the guiding rod, and the strand begins to be wound by the auxiliary winding skein frame.
At this point, the take-up collet is braked to a rapid stop and the strand is severed between the take-up collet and the auxiliary take-up skein. Then, the auxiliary winding skein frame, which is in the process of winding up the strand, retreats to the standby position, and the thread guiding rod further protrudes in accordance with the retreating speed. At this point, the collet stand moves rapidly, and the full collet moves to the bobbin removal position, and another collet with an empty bobbin inserted moves to the winding position. At this time, the auxiliary winding skein frame and the winding collet have reached a predetermined rotational speed. The auxiliary take-up skein moves forward, and the thread guiding rod retreats to a specific position as the auxiliary winding skein moves forward.Then, when the thread guiding rod retracts to the non-operating position, the strand winds up, and then the auxiliary take-up skein moves back. The upper waist strand is automatically removed. On the other hand, the full bobbin on the stopped collet is removed from the collet, and an empty bobbin is inserted and placed in a standby state for the next winding.

Therefore, unless the spun strand is broken for some reason, spinning and winding will continue, but if a break occurs due to fluctuations in spinning conditions or other causes, the focused strand will be The strand is reliably caught in the auxiliary winding frame by providing a predetermined transport path through the free end front surface of the winding collet through the protruding thread guide rod and through the front surface of the free end of the winding collet by means of the lower tension roller. The winding operation can be performed.

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

The rotating shaft rotates in conjunction with the rotation of the take-up collet 6 and makes reciprocating motion within the range indicated by ω.

The outer periphery of the tip of each peg 8 of the auxiliary winding skein frame 7 is arranged on a large-diameter concentric circle on the outer periphery of the winding collet 6, as shown by point 8' in FIG.

At the time when the above-mentioned winding preparation state is reached, the pressure cylinder 15 is activated and the auxiliary winding skein frame 7 operates the limit switch 22 during the transfer path of the strand S, and the tip of the peg 8 is moved to the winding collet 6. After confirming that the free end of the motor 14 has protruded to the outer periphery,
The driven rotation of the strand S is started, and the tensioned strand S is first stretched between the two pegs 8 to securely wind it and auxiliary winding is started.At the same time, the winding collet 6 is also driven and rotated, so that both When the rotational speed of the wire reaches a predetermined speed, the pressurizing cylinder 13 is actuated to rapidly draw the thread guide rod 11 to the non-operating position C, so that the strand S comes into contact with the rotating wire traverse device 10 and is pulled into the collection. 6, the wire traverse device 10
By reciprocating by ω in the axial direction, a winding layer as shown by the dotted line is formed.

During this time, the auxiliary winding skein 7 stops, and as a result, the strand is pulled and cut between the auxiliary winding skein 7 and the winding collet 6. Further, the pressurizing cylinder 15 operates in the opposite direction, and the auxiliary winding skein frame 7 retreats until it comes into contact with the limit switch 21, and at the same time, the wound waist strand is automatically removed. When the strand S' is fully wound on the take-up collet 6, the auxiliary take-up skein frame 7 advances and starts rotating, rapidly moving the thread guide rod 11 from the non-operating position C to the A position. The winding collet 6 is stopped and the strand is pulled and cut between the auxiliary winding skein frame 7 and the winding collet 6. The auxiliary take-up skein frame 7 rotates and retreats to the standby position, and along with this, the guide rod 19 protrudes to position B. Next, the collet support rotary frame T rapidly rotates 180 degrees to the full bobbin removal position, and the winding collet 6' with the empty bobbin inserted therein is moved to the winding position. At this time, the auxiliary take-up skein frame 7 and the take-up collet 6' are being rotated at a predetermined rotational speed by the motor drive device, and the strand S'' shown by the dotted line is wound on the auxiliary take-up skein frame 7.Auxiliary winding The holding frame 7 advances from the standby position while rotating, and the thread guiding rod 11 retreats from position B to position A. Thereafter, the thread guiding rod 11 is rapidly drawn into the non-operating position C. As a result, the strand S' is precisely wound onto the winding collet 6'.

The full bobbin is manually pulled out from the take-up collet 6 that has been moved to the full bobbin removal position, and an empty bobbin is inserted.

The above-mentioned operations of this device are performed by a program control mechanism using a normal sequence circuit at predetermined timings, and the above-mentioned operations are repeated until the strand S' is disconnected. ′ continues to be wound.

If the strand S' is broken, the device returns to the state shown in the second figure, and the large number of glass filaments 2 spun from the bushing 1 are manually collected and delivered to the sizing agent application roller 3 and the sizing roller 4. The strand S is pulled downward in contact with the strand S, and is inserted between the lower tension rollers 9a and 9b via the protruding thread guiding rod 11 surface to provide the above-mentioned predetermined transfer path and become ready for winding.
