Abstract

PURPOSE:To prevent a glass yarn-like substance from being cut off during the process of traverse and make it possible to continuously wind it by providing a yarn-like substance absorbing device for absorbing a yarn-like part together with air when changing over the winding of said yarn-like part from the fully loaded winding collet to an empty winding collet. CONSTITUTION:A fiber yarn part 6a is absorbed in, when said part 6a comes out of the winding fiber yarn end surface 3 of a fully loaded collect 2a with the tension dropping to zero. In parallel with this operation of absorbing the fiber part 6a, both winding collects 2a, 2b are turned, operation of winding the fiber yarn 6a is started through an empty winding collet 2b, and the fiber yarn part 6a absorbed in an absorbing inlet 12 is gradually taken out by the winding force of the empty winding collet 2b, and the fiber yarn part 6a on the upper side of the absorbing inlet 12 is also gradually taken out toward the absorbing inlet 12 side, allowing the fiber yarn 6a to be completely taken out from said absorbing inlet 12 in the end.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a filament-like winder that is configured to automatically and continuously wind a glass filament around a collet, such as a direct roving winder that continuously winds glass fiber. Specifically, the winding collet, which winds the glass filament by driving rotation while a predetermined tension is applied to the glass filament, has several winding collets on the same rotation axis. The collets are arranged so that their end surfaces are in contact with each other and rotate in the same direction at the same speed, and based on the detection result that a predetermined amount of the glass filament has been wound around seven of the collets, the glass filament is fully wound. Winding in which the filament part that is being wound around the collet is moved to the side of the winding collet in the protrusion adjacent to the fully wound collet, and the subsequent winding of the glass filament is automatically switched to the empty collet side. The present invention relates to a continuous glass filament winding device that is equipped with a switching mechanism.

This type of continuous winding device for glass filament, which has been generally known in the past, includes, for example,
There is a method described in Publication No. 0, in which, in order to traverse the filament from a fully wound collet to a second collet, as shown in FIG. 7, it is usually 500 m,
The filament part (la'), which is being wound at a high speed of about 1,000 mm, is turret-type glass filament winding (the margin below this page continues on the next page). An empty take-up collet (2b
′) side and wind the empty winder (2b) once, but the filament part (la')
Wrapping on the air collecting collet (2b') is a problem in which most of the glass thread is cut at the instant of θ, θ2tec, ~ θ, θj sac at the time of switching.
Many conflicts occurred.

As a result of investigating the cause of this thread breakage, we came to the following conclusion.

That is, as shown in Fig. 7 14), a fully wound collet (2a
As shown in Figure 7 (b), the filament part (la') in the winding state is pushed out to the idle winding part (2b') and the filament rjK portion (la') is Full roll colette (
At the time when the filament part (la') comes off the end face (3') of the winding filament (2a'), the winding force by the winding collet (2a') becomes zero or almost zero, so the moving speed is low. is approaching zero. In this state, the fully wound collet (2a) rotates as shown in FIG.
), the slack portion (4) is wound around the empty take-up collet (2b') as shown in 1 in Fig. 7, and in the state shown in Fig. 7, When the moving speed becomes zero or almost zero, the filament portion (la') begins to be rapidly wound up, and at that point, the filament portion (la') begins to wind up rapidly.
la'), winding at high speed from a stationary or almost stationary state;
With the instantaneous transition to a moving sensation, a very large acceleration occurs in the form of a pulse, and in proportion to this acceleration, a very large tension is generated in the thread-like body part (la'). The instantaneous tension causes the filament portion (la') to be severed.

The present invention was devised based on the above-mentioned cause of the filament being cut off at the moment of traversal of the filament from the striped winding collet to the empty winding collet. Its purpose is to prevent the glass from cutting when traversing, which is the original function of the glass winding device. The object of the present invention is to make full use of the advantages of being able to carry out moth and male cotton traversing without once stopping the operation of the winding device, and to be able to continuously carry out glass shooting field removal work.

The characteristic feature of the present invention, which has been made to achieve such an object, is that the glass filament continuous winding device described above is combined with the winding of the filament part from the full winding collet to the glass winding collet side. The present invention is equipped with a filamentous suction device that sucks in air together with air during replacement.

In this way, the action and effect of the failure case with /i: feature mechanism is a first-order trace.

In other words, in order to cough up the filament part during traverse by the tifl suction device, when the winding of the filament part is started by the chamber winding collet L, 1ij
The filament part drawn in by the filament suction device is first pulled out, and as it is pulled out, the filament part on the lower side of the filament suction device is gradually pulled out on the side of the filament suction device. As a result, even if the winding force at high speed by the empty winding collet suddenly acts on the filament part, it is buffered by the filament suction part by the filament I pumping device and the filament is Because the moving speed is gradually increased without any sudden winding movement, the acceleration does not become large.

Since no large instantaneous tension is generated and the glass filament can be prevented from being cut, there is the inconvenience of stopping the operation of the filament winding device etc. when the glass filament is cut during traverse. This allows continuous and efficient winding of the filament.

Next, an embodiment of the configuration of the present invention will be described based on the drawings.
