Description

[Detailed Description of the Invention] (Industrial Field of Application) This invention relates to a device that can adjust the innermost rotational position of a flyer presser to a constant position in a roving frame.

(Prior Art) Conventionally, in a roving frame, bobbin insertion after doffing has generally been performed manually. That is, as shown in FIG. 1, with the bobbin rail 5 raised to a position where the distance between the lower end of the spindle 2 of the flyer 1 and the bobbin receiving part of the bobbin wheel 3 is shorter than the bobbin length, first place the top of the bobbin on the spindle. 2, and then the lower end of the bobbin is placed on the bobbin wheel 3. As a result, the insertion bobbin is maintained slightly inserted into the lower end of the spindle 2. However, due to demands for automation of doffing work and bobbin insertion work, a bobbin 4 having a flange portion 4a formed at the top for easy handling is used, and as shown in FIG. 2, a bobbin wheel 3 is used. The bobbin insertion work has come to be automatically performed with a gap created between the top of the bobbin 4 inserted into the spindle 2 and the lower end of the spindle 2.

(Problem to be solved by the invention) However, when the bobbin 4 is automatically inserted into the bobbin wheel 3 as shown in FIG. There is a risk that the battledore section 9 at the tip of the arm section 8 of the presser 7 rotatably supported on one of the hollow legs 6 will hit the flange section 4a provided at the top of the bobbin 4, causing the arm section 8 of the presser 7 to break. In order to prevent this, the upper surface of the flange portion 4a is formed in an oblique shape that becomes lower toward the outside as shown in FIG. It was also considered to prevent the arm portion 8 from being damaged by being guided outward along the slanted portion, but even in this case, the battledore portion 9 is
When the presser hits the guide portion 10 that guides the spindle 2, it cannot escape to the outside and damage to the presser cannot be prevented.

The battledore part 9 starts winding, that is, the bobbin surface 4
When it comes into contact with the bobbin surface 4, a pressurizing force is generated by centrifugal force due to the rotation of the flyer.
It is necessary to be able to rotate further inward than the position where it abuts b. However, Pretusa 7
The innermost rotating position is hollow leg 6 and presser 7.
As mentioned above, the battledore part 9 was placed in the guide part 1 on the upper surface of the bobbin 4.
Some of them rotated to the position corresponding to 0, which sometimes caused damage as described above.

As a solution to this problem, there is a method described, for example, in Japanese Utility Model Application Publication No. 60-53760. However, this technology had the disadvantage of a complicated mechanism.

This invention was made to solve the above-mentioned conventional problems, and its purpose is to provide a flyer that can appropriately adjust the innermost rotational position of the presser rotatably attached to the flyer hollow leg. It's about doing.

(Means for Solving the Problems) In order to achieve the above object, this invention provides a flyer in which a presser is rotatably attached to a hollow leg having a roving passage. A contact surface is provided that is approximately parallel to the axis of the dynamic support shaft, and an adjustment bolt or the like that comes into contact with the contact surface to regulate the inner rotational position of the presser is provided on either the hollow leg or the presser. .

(Function) With the above-described structure, the inner rotation position of the pretusa battledore toward the roving bobbin is set at the optimum position by the contact between the adjustment bolt, etc. and the surface facing it, and the bobbin rail starts winding. Even if the battledore part comes into contact with the flange part when rising to the position, the arm part will not be damaged, and the next roving winding operation can be smoothly carried out.

(Example) An example embodying this invention will be described below with reference to FIGS. 4 to 7. As shown in FIG. 4, a presser 7 is mounted rotatably around support shafts 11, 11' mounted above and below the hollow leg 6 in the flyer body 1. The fryer body 1 is
The presser 7 has a support mechanism 12 at the upper end so as to rotate around the spindle 2, and the presser 7 is integrally formed with an arm part 8 extending in an arc shape from the lower end and having a battledore part 9 at the tip. Accordingly, it rotates from the winding start position to the winding end position in accordance with the amount of winding of the roving onto the bobbin.

The presser 7, which is rotatable relative to the hollow leg, has an abutment surface 13 formed approximately parallel to the axes of the pivot shafts 11, 11', while the hollow leg 6, located opposite the abutment surface 13, forming the seat 14;
A screw hole is provided in the seat 14, and an adjustment bolt 15 is inserted into it.
are screwed together. When determining the innermost rotational position of the battledore part 9, the bolts 15 are fixed at a position earlier than the maximum height position of the slanted part of the flange part 4a shown in FIG. The tip is brought into contact with the contact surface 13. In this way, the amount of protrusion of the adjustment bolt 15 from the hollow leg is determined, and it is fixed with the lock nut 16.

With this configuration, the battledore portion 9 is positioned inside the bobbin surface 4b at the innermost rotational position of the presser 7, as shown in FIG. 5, and the bobbin is inserted in the state shown in FIG. Then, when the bobbin rail 5 rises to the winding start position, even if the battledore part 9 is at the innermost position, it is guided by the oblique part of the flange part 4a at the tip of the bobbin and rotated away from the flange part 4a. Since the arm part 8 moves, there is no possibility that the arm part 8 will be damaged. As before, the outermost rotational position of the presser 7 is regulated by contact between the abutment portions formed on both the hollow legs 6 and the presser 7, and this state is shown in FIG. The battledore portion 9 is located further outside the roving surface 17.

This invention is not limited to the above-described embodiment; for example, as shown in FIG. 7, a spring pin 18 or the like may be used instead of the adjustment bolt.
Alternatively, an adjustment bolt or the like may be attached to the presser 7 side, and the contact surface may be formed on the hollow leg 6 side. Furthermore, the attachment position of the adjustment bolt etc. may be set at the lower part of the flyer, which is preferable because the abutment position will be near the arm part 8 and the inward rotating position can be ensured even if the entire presser is torsioned.

(Effects of the invention) As detailed above, according to this invention, the rotation range of the presser, which is rotatably attached to the hollow leg of the flyer, can be easily adjusted with a simple mechanism. The innermost rotational position of the part is regulated so that even if the battledore comes into contact with the flange of the bobbin when the bobbin rail is raised, the battledore will be guided outward along the slanted part of the flange. This has an excellent effect of reliably preventing damage to the presser.
