Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a detachable flyer device used for unwinding a yarn from an H-shaped bobbin having a collar.

[0002]

[Prior art]

 A so-called H-shaped bobbin with a collar is often used as a winding core of a yarn because it does not easily collapse, and conventionally a relatively small bobbin whose collar diameter is not so large compared to the height of the bobbin is used. Was there. On the other hand, in recent years, in general, various attempts have been made to increase the size of the bobbin to improve the production efficiency. In the case of the H-shaped bobbin, increasing the size of the bobbin also increases the diameter of the collar. When the yarn is unwound in the direction of the collar using the H-shaped bobbin thus enlarged, when the unwinding progresses and reaches the inner layer portion, the unwound yarn rubs against the brim portion, and thread breakage occurs. . In such a case, conventionally, a waste yarn is wound around the inner layer portion in advance, and only the yarns in the front and middle layer portions are used for unwinding.

[0003]

[Problems to be solved by the device]

 However, the waste is extremely large in the method using the waste yarn as described above. Further, when unwinding fine-fineness yarns or strong-twisted yarns, there is a drawback in that unwinding failure or unwinding state occurs if slight contact or fluctuation in tension occurs due to interference at the collar portion. The present invention solves such a problem, and an object of the present invention is to provide a fryer device which can always perform a stable unwinding regardless of the shape of the H-shaped bobbin and the type of the wound yarn.

[0004]

[Means for Solving the Problems]

 The present invention relates to an insertion portion that is detachably inserted into an axial hole of an H-shaped bobbin, a spindle that is erected on the insertion portion and is located on the axis of the H-shaped bobbin at the time of insertion, and a spindle of the spindle. It consists of a rotating arm that rotates freely around the circumference and is longer than the diameter of the collar of the H-shaped bobbin, and a plurality of thread guides that are provided with guide parts sandwiching the rotating arm in the spindle axis direction. At this time, the H-type bobbin unwinding flyer has an angle θ of 5 to 45 degrees formed by the spindle and the guide portion A of one yarn guide and the guide portion B of the other yarn guide.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a front view of the fryer of the present invention. In the figure, 1 is an insertion portion, 2 is a spindle, 3 is a rotating arm, 4 is a thread guide A, and 5 is a thread guide B.

The insertion portion 1 has a cylindrical member 11 that fits into the shaft hole of the H-shaped bobbin and a pedestal 12 provided on the upper surface of the cylindrical member 11. A large number of notches 13, ... Which are stoppers for prevention are provided. The spindle 2 is erected on the pedestal 12, and is provided at the center of the insertion portion 1 so that the axis line of the H-shaped bobbin and the axis line of the spindle 2 coincide with each other at the time of insertion. The rotating arm 3 freely rotates around the spindle 2, and is preferably formed symmetrically with respect to the spindle 2 so as not to lose balance even at high speed rotation. Further, the length of the rotating arm 3 should be longer than the diameter of the collar of the H-shaped bobbin into which the main flyer is inserted so that the thread guide B5 described later can be located on the side surface of the H-shaped bobbin. .

Now, the rotation arm 3 is provided with thread guides A4 and B5. The yarn guides are provided in the axial direction of the spindle 2 such that guide portions A41 and B51 sandwich the rotary arm 3, and in the case of FIG. 1, the yarn guide A4 is provided above and the yarn guide A4 is provided below. There are two types of thread guide B5.

In the case of the present embodiment, these mechanisms are formed around the rotary arm 3 in which both ends of the piano wire are bent downward and the tip ends thereof are bent guide parts B51. Then, a thread guide A4 made of another piano wire is wound around the piano wire forming the rotary arm 3, and a guide portion A41 is formed by bending the tip of the thread guide A4. Since the rotating arm 3 and the yarn guides A4 and B5 are symmetrical with respect to the spindle 2, two sets are formed. However, instead of one set of yarn guides A4 and B5, a simple balancing load is provided. Is also good.

In addition, in the case of the present embodiment, the piano wire which is the rotating arm 3 has a center portion formed in a circular shape and is loosely inserted into the spindle 2, and the rotors 61 and 62 and the stopper 63 are provided above and below the spindle wire. The rotary arm 3 is rotatably stopped by these. Further, in the present invention, the guide portion A41 and the guide portion B51 need to be provided with an appropriate angle. That is, although FIG. 2 is a top view of the fryer, the angle θ formed by the spindle 2, the guide portion A41, and the guide portion B51 needs to be 5 to 45 degrees. If the angle θ is less than 5 degrees, a sufficient force for rotating the rotating arm 3 is not generated when unwinding using the fryer, and if the angle θ exceeds 45 degrees, the guide portion is unwound. The yarn may be rubbed by A41 and fluff may be generated.

Next, unwinding using the present fryer will be described. FIG. 3 is a perspective view showing a state in which the unwinding process is being performed. As shown in the figure, the unwinding is carried out by pulling out toward the flange 71 of the H-shaped bobbin 7 and inserting the flyer F into the shaft hole (not shown) of the H-shaped bobbin 7. First, the yarn Y drawn out from the H-shaped bobbin 7 passes through the guide portion B51 and the guide portion A41 in this order, and is taken out in a direction substantially directly above the spindle 2. At this time, the unwinding of the rotating arm 3 proceeds while rotating counterclockwise in the case of FIG. 3 due to the angle θ between the guide portion A41 and the guide portion B51.

When unwinding a normal yarn, the unwinding may be performed as shown in FIG. 3. However, when unwinding the strongly twisted yarn, it is preferable to provide a mechanism for preventing kinking. FIG. 4 is a front view showing the unwinding process using the anti-rattle mechanism together. In the same figure, after the collar 71 of the H-shaped bobbin 7 is covered with the anti-rattle cap 8, the flyer F is inserted into the shaft hole 72 of the H-shaped bobbin 7. An anti-raveling gut 81 circulates on the side surface of the anti-rapping cap 8, and the yarn Y drawn out from the H-shaped bobbin 7 passes through the guide part B51, the anti-raising gut 81, and the guide part A41 in this order, and then the spindle 2 It is taken in almost directly above.

[Effect of device]

 According to the present invention, a stable unwinding is always possible regardless of the shape of the H-shaped bobbin and the type of wound yarn. In addition, since this flyer is detachable, it can be unwound easily, and can be applied to hard twisted yarns and the like that require anti-rattle caps.
