Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an improvement of a winding collet of a turret type winder.

Conventionally, when winding a glass fiber strand, for example, when one winding collet side bobbin is fully wound, the turret rotor is reversed 180 degrees, the standby side collet is moved to the winding side, and the bobbin is fully wound. A method has been used in which a brake is applied to the side collets and the winding is switched based on the peripheral speed difference between the two collets.

Problems to be Solved by the Invention However, in recent years, the strands to be wound (hereinafter referred to as yarn) have tended to become thicker, and switching errors may also occur due to changes in surrounding conditions such as dirt on the sizing agent, or low speed winding. tends to occur frequently. Although auxiliary devices and means have been used to prevent this, switching is still unreliable.

This invention solves the above problems and maintains switching stability when switching winding operation from the full bobbin side to the newly wound bobbin side, even against long-term changes in the surrounding conditions due to the above dirt etc. The purpose of the present invention is to provide a winding collet that can be used.

In order to achieve the above object, the present invention has a configuration in which a turret rotor 2 incorporating two take-up collections 1 in a cantilevered manner is reversed in a continuous automatic winding machine. Two rows of pin groups 11 and 12 are implanted on the front surface of the free end, and each of these pin groups is arranged on a circumference having two different radii relative to the axis of the winding collet, and the inner pin group 11 is The long pin 11a and the outer pin group 12 consist of short pins 12a.

Function According to the present invention, when the turret rotor is reversed and switched from one winding collet to the other winding collet, the waist yarn is reliably switched by utilizing two groups of pins planted in the front of the collet. You can switch to

Embodiments The present invention will be described below based on embodiments shown in the drawings. In FIGS. 1 and 2, the winding machine includes a turret rotor 2, in which two winding collections 1, 1 are protruded in parallel in a cantilevered state, is attached to the front surface of the winding machine main body 3, and the rotor 2 alternately winds the yarn onto the bobbins B1 and B2 attached to the two winding collects 1 and 1 while repeating 180 degree reversals. In this winding, the traverse guide bar 5 equipped with the butterfly wire 5a traverses back and forth (right and left directions in FIG. 1) to form a spiral layer.

According to the present invention, FIGS.
As shown in the figure, there are two rows of pin groups 11 and 12 on the front surface of the free end of each winding collet 1.
will be planted. These pin groups are arranged on a circumference with two different radii relative to the axis of the winding collet 1. Further, among these pin groups, the group 11 located inside is formed by long pins 11a,
The group 12 located on the outside is made up of short pins 12a that are shorter than the long pins 11a. According to the illustrated embodiment, the inner pin group 11 has eight pins and the outer pin group 12 has six pins.
Although it is composed of books, there is no limit to the number of books.

Reference numeral 4 shown in FIGS. 1 and 2 is a yarn guide 4 that protrudes when the turret rotor 2 is reversed and moves the yarn Y to the position of the pin group.
Piston-cylinder mechanism housed in (not shown)
Advancement or retreat is given depending on. A thread path 4a is formed at the tip of the thread guide 4 for catching and pushing out the thread Y.

Further, 2a shown in the second figure is a partition plate protruding from the turret rotor 2, which partitions approximately up to the vicinity of the free end side of the bobbin attached to the winding collet 1.
To prevent the yarn wound on one bobbin from scattering and winding on the other bobbin.

The operation mode will be explained above. When one bobbin B1 is fully wound, a separately installed reversing device causes the turret rotor 2 to follow the arrow (Fig. 3 P).
The yarn guide 4 is reversed 180 degrees, and at this time, the yarn guide 4 moves forward (rightward in FIG. 1) to move the yarn Y to the position of the long pin group 11 (as shown in FIG. 4 G1). at the same time,
The positions of the fully wound bobbin B1 and the bare bobbin B2 are switched. At this previous point, the yarn Y is on the bare bobbin B2
While being guided by the long pin 11a of the side collet, the fully wound bobbin B1 is wound around the long pin 11a of the side collet to form a waist strip. Next, when the thread guide 4 is retreated to the position of the short pin group 12 (shown in FIG. 4 G2) and the thread is moved, the thread Y is caught on the short pin 12b on the bare bobbin B2 side and is moved to the bare bobbin side. It will be wound around the short pin group 12. On the other hand, since the fully wound bobbin side collet is rotating at the same speed as or faster than the bare bobbin side collet at this point,
The yarn spanning both collets is cut between the two collets. When the thread guide 4 further retreats, the thread Y rides on the traverse guide bar 5, starts normal traverse, and is wound onto the surface of the bare bobbin.

One fully wound bobbin B1 is stopped from rotating, doffed, and the other bare bobbin is attached to wait for its next turn.

When the long pins 11a are tilted outward, the winding around the pin group 11 becomes more reliable and the pin effect is enhanced.

Effects of the invention As described above, the present invention has a group of long and short pins planted on the front surface of the take-up collet, and when the turret rotor is reversed, the guiding position of the yarn is shifted from the long pin group on the inside to the short pin group on the outside. Since it is moved, it is possible to reliably switch even when winding thick yarn or winding at low speed. In addition, stable switching is now possible without being affected by changes in the surrounding conditions caused by dirt, which is currently the most problematic issue. Furthermore, the structure is simple, leading to cost reductions and maintenance work is also labor-saving.
