Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a yarn guide device used when threading in a yarn winding machine.

[Conventional technology]

A so-called take-up device is known as a device for winding up yarn spun from a spinning beam.

In order to wind multiple yarns spun from a spinning beam with one device, this device inserts and supports multiple bobbins (paper tubes) into a horizontal rotating shaft. A thread hook is usually provided below the bobbin for threading.

The above thread hooks are arranged in the same number as the number of bobbins, and when starting work, the thread hooks are gathered in one place and each After hanging the thread on the thread hook,
The bobbins must be movable between positions where the bobbins are inserted and supported on the shaft and where they are spaced apart from each other.

[The problem that the idea aims to solve]

Various thread hooks have been proposed for the above purpose, but all of them have complicated structures and have many sliding parts and are prone to wear. In particular, it is difficult to process the members for regulating the thread hooks at predetermined intervals, which consist of metal rods that are passed between the thread hooks, and they tend to be bulky as a whole. Since there are many parts, it is easy for foreign matter such as dirt to get into the sliding parts, and in this case, the resistance during operation increases, making the work difficult.

In view of the above points, this invention aims to provide a novel thread guide device that has fewer sliding parts, has low resistance, operates smoothly, and can be made compact as a whole.

[Means to solve the problem]

The thread guide device according to this invention includes a rod that can move forward and backward along the bobbin arrangement direction of a yarn winding machine, a thread hook fixed to the tip of the rod, and a slide that is slidably attached to the middle of the rod. It consists of a flexible thread hook, the fixed thread hook, the slidable thread hook, and a belt body stretched between each thread hook between the proximal bearing portion of the rod. be.

〔Example〕

FIG. 4 is an overall view of a take-up device equipped with a thread guide device 1 according to this invention. A bobbin holder 4, a vertical switching device (not shown) for the bobbin holder 4, a lifting arm 5 that moves up and down with respect to the frame 3, and a traverse device that traverses the yarn on each bobbin B provided in the lifting arm 5. 6 and a friction roller 7 which rolls into contact with and rotates the package P wound on the bobbin B, and the bobbin holder 4
A thread guide device 1 used when threading the upper bobbins B all at once is disposed along and below the bobbin holder 4. 8 is the thread guide device 1
This is a thread transfer plate that introduces the thread into each slit S of the bobbin B in cooperation with the thread transfer plate 8. When the thread transfer plate 8 is tilted toward the bobbin, the thread guide piece 9 fixed to its upper side guides the thread into the bobbin. Guide to B.

Next, the thread guide device 1 according to this invention will be explained.

That is, as shown in FIGS. 1 to 3, the thread guide device 1 of this example includes a rod 11 that extends below the bobbin holder 4 and can move forward and backward along the bobbin arrangement direction, and a bearing portion of the rod 11 at one end. 12, a thread hook 14 fixed to the tip of the rod 11, and a plurality of thread hooks 15 attached to the middle of the rod 11 so as to be slidable with respect to the rod 11 (in this example, 4 pieces) and
The thread hook 16 fixed to the bearing part 12 of the housing 13 and all the thread hooks 14, 15, 1
Each thread hook 14,1
It consists of flexible belts 17 fixed every 5 and 16.

The thread hooks 14, 15, 16 are cylindrical members 14a, 1 whose diameter is smaller than the inner surface of the housing 13.
5a, 16a, and the cylindrical members 14a, 15a, 1
Pigtail-like thread hanging piece 14 protruding from 6a
b, 15b, 16b, but the trapezoidal parts 14c, 1 on the cylindrical members 14a, 15a, 16a
5c and 16c are fitted into slit openings 18 formed in the longitudinal direction of the housing 13 (FIG. 3), so that they slide relative to the housing 13 without rotation.

In addition, as mentioned above, the cylindrical member 14a is connected to the rod 11.
Each intermediate cylindrical member 15a is fixed to the tip.
is slidable with respect to the rod 11, and the cylindrical member 16a at the base end is slidable with respect to the rod 11 and fixed with respect to the bearing portion 12.

Each of the thread hooks 14, 15, and 16 is fixed to the belt 17 at regular intervals (corresponding to the interval between each bobbin B) by bolts 19 and retaining plates 21. Rod 11 is the first
When retracted into the housing 13 as shown in the figure, each thread hook 14, 15, 16 is attached to the bobbin B at regular intervals.
When the rods 11 are lined up in the lower part and pulled out from the housing 13, the belt 17 is bent and the thread hooks 14, 15, 16 are gathered at one place A on the front side as shown in the second figure. .

Note that the slit opening 18 of the housing 13
A slit opening 22 is also formed on the opposite side so that the belt 17 can freely extend and bend.

Further, in the above embodiment, the most proximal thread hook 16 is fixed to the housing 13, and the thread hook 16 is fixed to the housing 13.
The proximal end of the belt 17 is fixed at the most proximal end, and the thread hook 16 on the proximal end side is also slidable with respect to the rod 11 and also with respect to the housing 13. The belt 17 is extended to the right side of the housing 1, that is, to the bearing part 12, and the right end of the belt 17 is directly connected to the housing 1.
It may be fixed to 3.

Furthermore, instead of the cylindrical housing 13, another rail-shaped frame may be used that supports each thread hook 14, 15, 16 so as to be movable in the direction of the rod 11 but not rotatable. Cylindrical parts 14a, 15a, 16 of thread hooks 14, 15, 16
There may also be another shaft parallel to the rod 11 passing through a.

Next, a threading method using the thread guide device 1 will be explained.

That is, when threading, the operator first holds the grip 11a of the rod 11 and
Pull it out to the front and attach each thread hook 14, 15, 1.
Position A in front of the device, where it is easy to thread 6
(Figure 4). Then, by operating a suction device such as an air sucker that suctions a plurality of threads, each thread is hung one by one on the thread hooking pieces 14c, 15c, and 16c of the thread hooking devices 14, 15, and 16, respectively. Next, the rod 11 is pushed into the housing 13. Then, among the thread hooks 14, 15, 16, the leading thread hook 14 moves first, and then the middle thread hooks 15, 15... move in conjunction with each other one after another, and the thread hooks 14, 15, 16 move. Then, the thread passing plate 8 is tilted in the direction of the bobbin B to simultaneously guide the threads passing vertically to the bobbin B. Wrap it around.

When the above operation is completed, the yarn transfer plate 8 is returned to the upright position shown in FIG. 4.

It goes without saying that the thread hooking pieces 14b, 15b, and 16b can be changed to various other shapes instead of pigtail shapes.

[Effect of idea]

As described above, the thread guide device according to the invention has few sliding parts, moves easily, hardly requires replacement of parts due to wear, and can be constructed compactly as a whole.
