Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a magazine cotton collection device, and more particularly to a magazine cotton collection device that collects fluff scattered from a bobbin during yarn feeding.

[Prior Art] Yarn produced in a spinning process is wound onto a single-strand bobbin. A winder is known as a device that rewinds yarn wound onto a package cage while splicing yarn wound around multiple bobbins.

This winder 1 is constructed as shown in FIG. As shown in the figure, a plurality of side frames 2 of the winder 1 are formed, and each of these side frames 2
A shaft or pipe 3 and a traction pipe 4 are interposed between them. A winding unit 5 is rotatably supported on the shaft 3. While the winder 1 is in operation, the winding unit 5 is also placed on the suction pipe 4 and is properly fixed. The inside of the syringe pipe 4 is constantly suctioned by a blower (not shown).
Bobbin 6 in the above winding unit 5
To unwind the thread 8 from the bobbin 6 to the package 7, the thread 8 is passed from the bobbin 6 on the peg 9 through the guide 10 and given appropriate tension by the tensor 11, and is used to detect and cut thread irregularities such as thread lumps and slabs, and to detect thread running. The package passes through a detection device 12 which also serves as a detector, and is wound onto a package 7 which is rotated by a winding drum.

Since the threads 8 of a plurality of bobbins 6 are wound back onto the package cage 7, some winders 1 have a magazine for smooth winding.

This magazine accommodates a plurality of bobbins 6, and in addition to the bobbin 6 that feeds yarn, a spare bobbin 6
FIG. 5 shows a three-ring type magazine 13. As shown in the figure, a peg 9 is provided on the table 14 of the magazine 13, and a bobbin 6 is attached to this peg 9. In the case of the three-ring type magazine 13, three pegs 9 are provided at 120° intervals, and three bobbins 6 are attached. These bobbins 6 are provided with a partition wall 15 between them. This partition wall 15 is fixed between the Y plate 16 and the table 14. A rotating shaft 17 is inserted through the center of the Y plate 16 and the table 14, and the magazine 13 is configured to rotate about this shaft by 120 degrees. One of these three bobbins 6 is located at a yarn feeding position 18, and the other two are located at a standby position 19. When the supply of yarn 8 to the bobbin 6 located at the yarn feeding position 18 is completed, the magazine 13 is rotated 120 degrees to position the bobbin 6 that was in the standby position 19 to the yarn feeding position 18, and the bobbin 6 after being fed is 6 is replaced with a new bobbin 6. This magazine 13 is specially designed for carpet yarns of 450~
This is used when rewinding a large bobbin 6 of 460 mm.

In addition, 20 in the figure is a guide plate for guiding the thread 8.

[Problems to be solved by the invention] By the way, this type of magazine has the following problems.

As mentioned above, the magazine 13 is used to rewind the large bobbin 6 for carpet yarn, but due to the nature of carpet yarn, the thread 8 is
A lot of fluff is generated when it is fed out. This fluff is supplied while the yarn 8 is directed upward to form a balloon, so that it rides on the rising air current and scatters. However, since the conventional magazine 13 is not equipped with any kind of cotton collection mechanism, the wander 1 of the type having this magazine 13 has been problematic as an apparatus in which a large amount of fluff is scattered.

In view of the above-mentioned problems, it is an object of the present invention to provide a carpet yarn winder with less scattering of fluff by providing a magazine capable of preventing the scattering of fluff.

[Means for Solving the Problems] In order to solve the problems in the prior art, the present invention provides a cover member to surround the bobbin located at the same position at the yarn feeding position of the magazine together with the partition wall of the magazine, A suction nozzle equipped with a suction means for suctioning fly fluff scattered within the portion is provided above the yarn feeding position covered by the partition wall and cover member.

[Operation] The bobbin located at the yarn supplying position of the magazine supplies yarn while forming a balloon upward so as to wind the yarn back to the package provided above. As a result, an upward air current is generated at the yarn feeding position. Riding this rising air current, the fluff generated from the yarn during feeding is scattered. However, in the present invention, since the cover member surrounds the bobbin located at the yarn feeding position, together with the partition wall of the magazine, the yarn does not scatter to the outside from the yarn feeding position. Since a suction nozzle equipped with a suction means is provided above the yarn feeding position covered by the partition wall and the cover member, the fluff rising from this yarn feeding position is sucked and cotton collection is performed. It is something.

[Embodiments] One embodiment of the magazine cotton collection device of the present invention will be described below in detail with reference to the accompanying drawings.
