Description

{Yarn Winder}

The present invention relates to a winding apparatus, and more particularly, to a special yarn winding apparatus capable of quickly and accurately winding a special yarn such as a coating yarn or a spun yarn into a branch tube by finely controlling the tension of the yarn by electromagnetic means.

The yarn is wound on the core tube in a finished state through various processing processes such as spinning, coating, dyeing, and twisting, and then is input into the weaving process. However, the yarn can not be rolled into a state that can be immediately woven through the treatment process. In other words, winding the yarn on the branch tube also takes two steps.

The yarn that has undergone the final fabrication process is wound primarily parallel to the branch. Thereafter, the yarn is rewound in the oblique direction before being input into the weaving machine. This is because, in the state of being wound in parallel, the yarn breaks without being able to overcome the tension in weaving. The yarn must be wound in a diagonal direction on the branch tube in order to be fed to the weaving machine while being loosened.

The present invention relates to a winding apparatus for unwinding a yarn wound around a branch in parallel and transferring the yarn to another branch in a diagonal direction again.

The conventional winding apparatus uses a cam screw as a mechanical type. That is, in order to wind the yarn on the paper tube having a limited length, the drum having the guide groove sloped continuously in an oblique shape is axially rotated, and the guide ring threaded along the guide groove on the drum is continuously moved left and right So that the thread is evenly wound along the longitudinal direction of the branch tube.

In this type of method, the shape of the guide groove provided in the drum or the length of the drum is determined, so that the yarn can be wound on the branch tube in only one manner. Especially, the above-mentioned special yarn is very difficult to be wound by using the conventional mechanical method. Here, the special yarn refers to a yarn widely used in functional sneakers, leisure goods, or sportswear, because it has excellent warmth, excellent sweat releasing ability, and high elasticity. These yarns are easily broken when weaving using a general winding machine. If the yarn is broken well, the operation of the process should be stopped, and all of the materials that have been input during this time will be lost due to the waste and the length of the weaving fabric.

Meanwhile, in the related art, the special yarn is often made of a coating yarn wrapping around the examination and examination. However, when the conventional mechanical winding device is used, the yarn wound inward (that is, the yarn close to the branch tube) The phenomenon of decomposition often occurs. Then, the special company made up of the examination and coating company becomes unable to exert its own function, so that the defect is abused. This problem is caused by winding the yarn around the branch tube with a constant tension throughout. To alleviate this problem, if the tension is lowered a little, there is a problem that the winding thread breaks down if the branch tube is set up. As a result, conventional mechanical winding devices can not handle various kinds of special yarns which have been widely demanded in recent years.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. Reference will now be made basically to Figs. 1 and 2 and other drawings will be referred to as necessary.

The special yarn winding device of the present invention is specially designed for winding special yarn. However, it is needless to say that the scope of rights of the present invention is not limited to the recommendation of special history. Here, the term special yarn refers to spun yarn, coated yarn, and fine yarn.

A first paper tube seat (3) for seating a first paper tube (1) wrapped with a thread through a yarn manufacturing process is provided at the bottom of the winding device.

The second paper tube fixing table 7 for fixing the second paper tube 5 inserted into the weaving process and releasing the thread T of the first paper tube 1 and rewinding the second paper tube is installed on the upper side of the winding apparatus. The second paper tube fixing table 7 includes a paper tube shaft 9 into which the second paper tube 5 is inserted and a shaft housing 11 into which the paper tube shaft 9 is rotatably fitted via a bearing. The shaft housing 11 can be rotated in the direction of the arrow K about the hinge shaft 13 provided at the lower portion thereof in a direction perpendicular to the branch tube shaft 9 (see FIG. 3). The second paper tube fixing table 7 is a part that is similar to the conventional technology, and a detailed description thereof will be omitted.

The branch tube shaft 9 provided at the upper end of the shaft housing 11 is supported by the pressing drum 15 by the own weight of the shaft housing 11. The pressing drum 15 presses the yarn T to wind the yarn T so that the wound yarn is not loosened and assists the yarn T to tighten more tightly. The second branch tube (5) is fitted to the branch tube shaft (9) and then fixed by the nut cap (17).

And the second branch tube rotating part rotates the second branch tube 5. 3, the second branch pipe rotary part includes a drive motor 19 and a transmission belt 21 to a pulley 23 that transmit the rotational force of the drive motor 19 to the branch pipe shaft 9. [

The winding device of the present invention has a base plate (25) installed upright. On the one surface of the base plate 25, there is provided a coupling portion for coupling the thread of the first branch tube 1 to the second branch tube 5. The coupling portion includes a plurality of rollers (27, 29, 31, 33, 35, 37) mounted on the upright base plate (25). And a tension adjusting unit for adjusting the tension of the yarn T is provided at the connecting portion. The tension adjusting unit functions to keep the tensile force of the yarn fed to the second core tube (5) constant while being released from the first core tube (1). Conventionally, a weight corresponding to the weight of the weight has always been applied until it is wrapped around the second core tube 5 by using the weight.

However, according to the present invention, the tension adjusting unit uses the main brake 39 made of an electromagnetic type. The main brake 39 is in the form of a motor having a rotating shaft, and a change in rotational resistance of the rotating shaft serves as a means for controlling the tension. A brake roll 29 is coupled to the rotor of the main brake 39. [ The user can arbitrarily adjust the torque of the rotor. In particular, the tension can be set depending on the characteristics of the yarn T, the degree of winding to some extent, and the like.

A guide portion (41) is provided between the linking portion and the second paper tube (5). The guide part 41 feeds the yarn T extending to the second branch tube 5 while moving the yarn T back and forth along the longitudinal direction of the second branch tube 5. According to the embodiment of the present invention, the guide part 41 includes a linear motor 45 (linear), which can adjust the slider 43 to linearly reciprocate at a desired speed in a desired section W, a guide ring 47 provided on the slider 43 and on which a thread T is threaded. This linear motor 45 makes it possible to freely set the distance and the speed of the conveying section of the slider 43. Therefore, regardless of the length of the branch pipe used, it is possible to set the feed interval according to the branch pipe. The shape of the yarn T wound on the branch tube can be freely set as shown in Figs. 8 (a), 8 (b) and (c). It is possible to determine, for example, whether the inclination of both ends of the wound thread is gentle or steep. In order to prevent the linear motor 45 from overheating, a cooling device 48 using a thermoelectric semiconductor may be installed so as to surround the main body of the linear motor 45 (see FIG. 4).

According to another aspect of the present invention, the apparatus further includes a softening agent application means 49 for the special yarn. The softening agent is a device for preventing breakage of the yarn when weaving, and is a device that can not be used in the conventional mechanical winding device because there is a problem that the yarn is loosened because the tension can not be controlled. However, since the winding device of the present invention can control the tension, the softening agent application means can be employed.

The softening agent application means 49 is provided in the middle of the linkage portion. The softening agent applying means 49 includes a softening agent chamber 53 capable of containing a liquid softening agent 51 and a softening agent agent 53 for guiding the chamber T to be immersed in the softening agent contained in the softening agent chamber 53 And a suction unit 55 installed at a rear end of the softener so as to remove excess softening agent from the chamber passing through the softening agent 51. [ The suction part 55 uses a sponge-type absorbent material. The softening agent may be supplied from the softening agent pack 51a installed so as to hang on the upper part of the apparatus.

The softening agent container 53 can be made of transparent acrylic and the softening agent supply part can automatically supply the softening agent by including an on-off valve connected to the sub tank 57 and the sub tank 57.

According to another embodiment of the present invention, the softening agent application means can be implemented through the softening agent dispensing portion 70 as shown in Figs. The injection of the softening agent using the injection nozzle 71 is installed on the upper part of the apparatus so that it can be directly sprayed onto the paper tube 5 to be wound. The spray nozzle 71 can be installed on the nozzle base 72 fixed on the nozzle seating plate 73 to spray the softening agent while moving left and right along the rail groove 74 as shown in Figure 7 (b) . However, as shown in FIG. 7 (a), it is also possible to inject the softening agent while spraying the injection nozzle 71 repeatedly at a constant angle like a wiper.

According to another embodiment of the present invention, when the yarn T wound on the first branch is completely wound or broken, a real yarn edge sensor 59 is provided on the top of the first branch yarn 1 and on the first roll 27 As shown in Fig. The real-feeling sensor 59 transmits a signal to the drive motor 19 and the linear motor 45 immediately after detecting the presence of an abnormality, thereby stopping the operation of the apparatus and giving a signal to the operator.

According to the embodiment of the present invention, it is possible to further include a damping lever 61 having the other end centered on one end and performing a pendulum motion within a constant interval such as a watch. A damping roll 35 is provided at the lower end of the damping lever 61, and the yarn passes through the damping roll 35. The damping lever 61 maintains the tension of the yarn constant while pendulum movement is performed at the same cycle as the slider 43 of the linear motor 45 about the shaft 63 provided at the upper portion of the damping lever 61. The damping lever 61 moves like a watch due to its own weight, and compensates for the difference in length between when the thread is wound around the edge of the core and when it is wound in the middle.

According to another embodiment of the present invention, the auxiliary braking device 80 may be installed as shown in Figs. 1 and 5. The operator can select the main brake 39 or the auxiliary brake 81 which is made of an electromagnetic type according to the characteristics of the yarn. The auxiliary brake 81 is also electromagnetically braked and selected to be able to wind the yarn with greater tension than the main brake 39. [

In particular, the auxiliary brake 81 is installed so as to be movable along the slot provided in the base plate 25 as shown in Fig. The auxiliary brake 81 is fixed to a bracket 84 that starts along a rail 86 provided on the rear surface of the base plate 25. [ And the piston 83 of the pneumatic cylinder 82 can be supported by the bracket 84 at a constant pressure. That is, when an excessive tension is applied during the winding, the pressure of the piston 83 is won and the auxiliary brake 81 is elastically moved to the left and right so that the yarn can be prevented from being broken.

The configuration shown and described above is merely a preferred embodiment based on the technical idea of the present invention. It will be understood by those skilled in the art that various changes and modifications may be made without departing from the scope of the present invention. All of the above embodiments may be used in any combination, and unexplained combinations are also included in the scope of the present invention.
