Description

TECHNICAL FIELD

The invention is related to a mechanism facilitating the separation of entanglement of the yarns more than one in form of bundle or clamp for the next process.
The invention is especially related to a yarn separating mechanism including a three dimensional flapping element providing more practically separation of the yarns in form of said bundles or clamps with three dimensional flapping effect, applied to a lot of textile machines working yarns in form of bundles and clamps and have to separate these again in the next step.

BACKGROUND

In today's textile industry, there are a lot of machines gathering more than one yarn together to form a bundle firstly, then subjecting them to many different yarn processes and then separating them again. For example, in yarn steaming or heat-set (machine of twist fixing by heat) applications, to keep the production high, lots of yarns are gathered together and passed through steam and/or heat tunnel. Then, in order to finalize the product (to wind on a coil or bobbin), this yarn bundle should be separated again.
When yarn bundles are subjected to yarn working process including heat, steam or both of them, yarns are partially deformed and intertwined. This situation complicates the yarn separation process.
In today's current applications for yarn separation, a yarn separating path with separator combs according to number of yarns to separated, found on this path is used. Generally high tension is applied for the functioning of the yarn separator combs on this path and for not breaking of the yarns by strolling. Yarn tension rollers are used to provide this tension.
These tension rollers rub while yarns passing over, therefore work with partial braking logic. Length of the friction zone, and yarn circulation angles determine the tension.
Another method is two dimensional polygonal rollers to be located on the separation line flapping effect is applied to whole yarn bundle strolling over these polygonal rollers in same directions and in equivalent time interval. This flapping effect provides disassociation of the coherent yarns.
In the yarn separating mechanisms used in the state of art, method of opening yarn entanglement is giving excessive tension to the yarns. Rollers are used to provide the tension. As the roller surfaces are continuously in contact with the yarns, yarns are heated and this affects negatively the yarn quality.
In the yarn parsing mechanisms used in the state of art, the yarn separating path requires highly long process. Consequently, it requires longer total machine installation length. This causes covering up too much space of the machine in production sites.
In the yarn separating mechanisms used in the prior art, more time is spent for separating the yarns as the separation period is long.
In the yarn separating mechanisms used in the prior art, more workmanship is needed for separating the yarns.
In the yarn separating mechanisms used in the prior art, production is less because of above mentioned problems.
New embodiments should be put forth in yarn separating mechanisms to solve above mentioned problems starting from this position of the technic. The invention is put forth to solve above mentioned problems.
As a result, yarn separating mechanisms are developed parallel to the developing technology in the yarn separating mechanisms; therefore, new embodiments are needed to eliminate above mentioned disadvantages and to find solutions for the current systems.

DETAILED DESCRIPTION OF THE INVENTION

In this detailed description, preferred embodiments of the yarn separating mechanism including a flapping element (20) are described only for better understanding of the subject without any limiting effects.
A multi bundle yarn (D) or clamp (A) coming from any yarn processing period, is firstly extruded from a yarn tension mechanism (10) to provide necessary tension for yarn opening and separating process. Rollers (11) are positioned on the yarn tension mechanism (10). For the rotating movement of the rollers (11) around their own axes, a shaft (13) is positioned in the middle part of the said rollers (11). A connection part (12) providing the interconnections of the rollers (11) at certain distance from the ground, and connected with the shafts (13), is positioned. There is a three-dimensional flapping element (20) according to the invention, which is mutually positioned against the yarn tension mechanism (10). In the middle of said flapping element (20), there is a bearing element (23) providing rotation of the flapping element (20) from outside or by the yarn actuation. There is a connection part (24) coupled to the flapping element (20) providing staying the flapping element (20) in a certain distance from the ground.
Then, the yarns (11) from tension rollers (11) are strolled over the three-dimensional flapping element (20) and finally the yarns are sent as separated for the next yarn process over yarn allocation comb (30). Because of this circular movement (F) and the structure of the three-dimensional flapping element (20), three-dimensional flapping effect is applied to the yarn bundle (B) between the three-dimensional flapping element (20) and the yarn tension mechanism (10). In the same way, the three-dimensional effect is applied to the yarn (C) between the yarn allocation comb (30) and the three-dimensional flapping element (20).
Three-dimensional flapping effect is obtained thanks to the polygonal rollers (26) located at variable angles (5 a, 5 b). As shown in FIG. 6, the yarns (10 a) in the polygonal roller (5 a) with 5 a angle are moved in Z direction and the yarns (10 b) in the polygonal roller (5 b) with 5 b angle are moved in X direction. By circular rotation (F) of the three-dimensional flapping element (20), position of the polygonal roller (5 a) with 5 a angle and the polygonal roller (5 b) with 5 b angle is changed. As a result of this, the yarns (10 a) moving to Z direction are moved to X direction, and yarns (10 b) on the X direction are moved in Z direction. In this period, three-dimensional effect is always provided by rotating of the three-dimensional flapping element (20).
This three-dimensional flapping effect provides easy separating of the yarns in the yarn bundle (A) coherent by the yarn allocation comb (30). Elements determining the flapping effect are the number of corners, diameter (M) and rotation speed of the polygonal roller (26). As shown in FIG. 6, while yarn is in contact with the corner, the angle between X plane and the yarn is α. The flapping effect is increased as the angle a gets bigger. Consequently, there is flapping effect with higher amplitude (flapping effect is higher) as the number of corners is decreased (FIG. 7) and there is flapping effect with lower amplitude flapping effect is lower as the number of corners is increased (FIG. 8).
The length (M) between the rotating axle and the corner of the flapping element (20) affects the flapping rate. Namely, flapping length gets longer as M gets bigger, flapping length gets shorter as M gets smaller.
Frequency of the flapping effect is determined by the speed of the polygonal roller (20). If desired, the yarn bundle (A) can be extruded strolling over the three-dimensional flapping element (20) and the rotation (F) of the three-dimensional flapping element (20) by effect of this can be provided. Optionally, the three-dimensional flapping element (20) can be rotated by any exterior actuator (40). Even speed of this actuator (40) is made variable by a suitable device (50) and variable flapping effect frequency can be obtained. Three-dimensional flapping element (20) thanks to its simple structure can be used in different working conditions and environments by manufacturing from aluminum, chrome or similar metallic or PVC, Bakelite, Teflon, wood or similar non-metallic materials.
The scope of protection of this invention is given in claims and can't be limited with the above mentioned description for sampling. It is clear that a person skilled in the art can implement the novelty put forth in the invention in other areas with similar purposes. Consequently it is obvious that such embodiments are lack of going beyond criteria of novelty and especially background art.
