Is.

2. Description of the Related Art In a conventional yarn feeder, a large number of rods installed on the outer circumference are fixed between an upper member and a lower member and perpendicularly to those upper and lower members. Therefore, the outer peripheral portion of the yarn feeder has a linear tubular shape.
With such a structure, it is difficult to automatically and orderly arrange the yarn when the yarn is wound around the surface of the yarn by the feeder. For this reason, thread delivery and thread feed do not always go smoothly.

In this regard, as an example of a commonly used solution, for example, U.S. Pat. No. 3,827,645 has one slanted disc 6 fitted on the outer circumference of a yarn feeder. U.S. Pat. No. 4,138,866 has one pressure cam 15 on the side of the yarn feeder. In this way, the yarns that go around the outer circumference of the yarn feeder can be arranged in an orderly and orderly manner.

However, the installation of the inclined disc or the pressing cam as described above complicates the structure of the yarn feeder and makes maintenance troublesome.

In addition, the following can be listed as the biggest drawbacks. That is, when exercising or when the yarn is broken and the yarn is spliced again on the feeder, the disc or the pressing cam as described above becomes an obstacle on the feeder, which is considerably inconvenient. Further, when the bearing of the disc or the pressing cam fails and the feeder cannot be synchronized with the feeder, the yarns on the feeder become entangled, which requires a considerable amount of time for processing.

An object of the present invention is to improve the above-mentioned drawbacks of the conventional yarn feeder, and to provide a yarn feeder which has a simple structure, is easy to operate, and has few failures.

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention connects the upper end of each of a number of rods to a top member in a tiltable manner along the circumferential direction, and The lower end is connected to the lower member so as to be tiltable along the circumferential direction, and a large number of rods form a yarn feeding outer peripheral portion along the circumferential direction between the upper member and the lower member, and extend in the vertical direction. An upper member and a lower member are rotatably provided with respect to the main shaft, and at least one of the lower member and the upper member is rotated in an arbitrary direction of a clockwise direction and a counterclockwise direction so that a large number of rods can be properly tilted. It is possible to tilt along the circumferential direction in any direction of clockwise and counterclockwise so that it has an angle, and a column is provided on one of the upper member and the lower member and a hole is provided on the other. Depending on the number of upper and lower members If not, the relative rotation range of one side is restricted to limit the tilt angle of the rod, and the yarn that circulates around the surface of the thread feed outer peripheral portion within the range of the tilt angle of the rod thus limited is automatically SUMMARY OF THE INVENTION A gist of a rod-adjustable yarn feeder is characterized in that it is arranged in an orderly manner and is further axially moved upward or downward to smoothly wind and wind a yarn.

Function In the present invention, as a means for achieving the above-mentioned object, a large number of rods arranged on the outer peripheral portion of the yarn feeder can form an appropriate inclination angle along the circumferential direction.

With such a configuration, an axial propulsion force is generated during operation of the yarn feeder, and the introduced yarn spirally turns downward or upward around the outer peripheral portion of the feeder to wind the yarn, thereby stabilizing the yarn. You can perform smooth thread winding and thread feeding.

Similar to the above method, the peripheral portion of the lower member 21 is also provided with recesses (not shown) at equal intervals, similarly to the upper member 11.
The lower end hook 32 of the rod 30 is inserted into the recess of the lower member 21, leaving a considerable margin in the recess so that the lower end hook 32 of the rod 30 can be laterally eccentrically moved (rotatable). Configure.

In order to simplify the assembly work, an upper outer lid 12 and a lower outer lid 22 are attached to the outside of the upper and lower members 11 and 21, respectively.
It facilitates the installation work of the rod 30, and also ensures the eccentric movement of the rod 30.

As shown in FIG. 2, the upper and lower members 11 and 21 are integrated by combining them in a mutual insertion method. That is, the central convex portion 211 of the lower member 21 is inserted into the central concave portion 111 of the upper member 11. The bush 62 is put in the hole located inside the central convex portion 211 of the lower member 21, and the both are combined, and these are attached to the main shaft 60. Moreover, the washer 61 is laid under the bush 62 so that it can be firmly fixed under the pressure of the spring 72. Furthermore, both the upper and lower members 11 and 21 are allowed to rotate alternately within a certain angle range.

A large number of arc recessed holes 110 are provided on the outer periphery of the central convex portion 111 of the upper member 11, and the columns 210 installed on the outer periphery of the central convex portion 211 of the lower member 12 are inserted into those holes 110 to form the lower member. twenty one
