Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a fly dust scattering prevention device for a winder.

[Conventional technology]

In winders, as a measure to remove cotton dust, a truck with a cleaning pipe consisting of a suction pipe or a blow-off pipe may be reciprocated along the ceiling rail above the winder, and
-By the air curtain as shown in 6779,
Various devices have been proposed.

[Problems to be solved by the invention]

In any of the above devices, it is difficult to completely remove the fly dust generated from the winder, and in the case of a moving cleaning tube, the winding unit is only intermittently cleaned, which is extremely insufficient. In the type such as an air curtain that intensively ejects a band-like air current from above the winder toward the front of the winding unit, the air pressure is diffused in the lower yarn feeding bobbin, that is, near the place where the cotton dust is most likely to occur.
A large amount of cotton dust generated from the yarn supply bobbin is scattered into the atmosphere, which is a major cause of polluting the air in the factory.

The present invention solves the above-mentioned problems and provides an apparatus capable of extremely effectively discharging cotton fly generated from a winder.

[Means for solving problems]

The present invention relates to a winder having a cotton wool suction means for sucking cotton wool generated by yarn unwinding from the yarn supplying bobbin, wherein the covers are opened and closed when the bobbin is taken in and discharged. And a cylindrical balloon guide for controlling ballooning of the loosened yarn is provided in the cover just above the bobbin, and the balloon guide is attached to one of the pair of covers. In addition, when the cover is opened / closed, the balloon guide moves in accordance with the opening / closing operation of one of the covers.

〔Example〕

FIG. 9 shows an example of the winding unit. The winding unit (1) is fixed in position by the support pipe (2) and the suction pipe (3), and the yarn (Y) drawn from the yarn supplying bobbin (4) that is positioned and fed to a predetermined position of the unit is a tenser (1). 7), the slab catcher (8) and the like are passed by guides (9), (10), (11) and (12) and the like, and wound by a traverse drum (13) into a winding package (14) that rotates. (15) is a yarn splicing device, (16) is a suction mouth that guides the package side yarn to the yarn splicing device (15), and (17) is a yarn feeding bobbin side yarn that is guided to the yarn splicing device (15). Each winding unit has the above-mentioned members, and a large number of such winding units (1) are arranged in parallel to constitute one automatic winder.

Although various methods are applied to supply the yarn supplying bobbins (4) to the predetermined positions of the winding unit (1), in the present embodiment, the yarn supplying bobbins (4) are individually provided in bobbin trays (18). ), The winder of the type that conveys and feeds to the winding unit, winds it, and discharges it from the unit. Of course, various winders are applied, such as one in which each unit has a magazine that stores multiple bobbins, or one in which each winding unit is not a fixed type as described above but moves cyclically along an elliptical orbit. It is possible.

Further, in FIG. 1, when a spinning bobbin after a ring spinning machine is used as the yarn supplying bobbin, the yarn is in contact with the yarn in the unraveling portion (A) or the tensor portion (B), or A large amount of cotton wool is generated due to the contact between the thread and the tensor part. Covers (19) and (20) are provided at the locations where the fly dust is generated to cover the locations.

Next, the cover for covering the periphery of the bobbin will be described with reference to FIGS.

In FIGS. 1 and 2, a bracket (22) is screwed (23) to the frame (21) of the winding unit,
A pair of covers (19a) that can be opened and closed on the bracket (22)
(19b) is pivotally supported on the shaft (24).

When the covers (19a) and (19b) are closed, the covers are in a substantially quadrangular shape in a plan view as shown in FIG. 2, and when the two-dot chain lines (19a1) and (19b1) are open, the bobbin of the winding unit is opened. It is separated from the passages (25) and (26), and there is no problem in discharging the bobbin from the winding position and taking in the new bobbin to the winding position (27). Further, since the bobbin covers (19a) and (19b) have a quadrangular cross-sectional shape as shown in FIG. 2, an ascending airflow is easily generated in the clearance space at each corner portion, and thus the ascending movement of the cotton wool is smooth. Become.

In addition, the contact of the ballooned yarn with the cover is less than that of the cover in the cylindrical shape, and the resistance and damage given to the yarn are less.

The one cover (19a) is fixed to a revolving structure (28) pivotally supported by a fixed shaft (24), and an operating rod (29) is connected to one end of the revolving structure (28), and similarly the other cover (19a). Cover (19
b) is also fixed to the revolving structure (30) pivotally supported by the shaft (24),
The rod (31) is connected. (32) is for each cover (19
a) A stopper that regulates the closed position of (19b).

Therefore, the rods (29) and (31) for opening and closing the covers (19a) and (19b) move in opposite directions. That is, as shown in FIG. 3, the rod (29) for the cover (19a) and the rod (31) for the cover (19b) are uniaxial (3
3) is connected to both ends of a lever (34) that swings about a fulcrum. The lever (34) operates as a rod (35) and a lever (36) that move in the direction of the arrow (35) in response to a bobbin change command. Exercise together. The spring (37) shown in FIG. 2 is for protection against breakage.

Next, the structure of the covers (19a) and (19b) will be described. The covers (19a) and (19b) have symmetrical shapes, and only one cover (19a) will be described.

In FIGS. 4 to 6, the cover body (19a) is integrally formed by, for example, aluminum die casting, and the central portion in the height direction has a substantially constant cross-sectional area. The central portion (38) covers the yarn layer surface of the yarn supplying bobbin in such a shape that it also decreases downward. A mounting portion (40) for mounting the balloon guide (39) disposed inside the cover is formed on one side surface of the cover (19a), and the other one side surface is mounted on the revolving structure (28). It is formed as (41).

The balloon guide (39) is shown in Figs.
As shown in FIG. 8, a part of the cylindrical body is cut, one semi-cylindrical body (42) is fixed to one cover (19a) of the cover to be opened and closed, and the other semi-cylindrical body (43) is fixed to the other half. The cylindrical body (44) is integrally formed on the semi-cylindrical body (43) so as to be fixed to the cover (19b), and the three blades (45) (46) (47) are oriented toward the center of the cylinder. It is fixed on the body (44). When the yarn runs, the balloon guide (39) passes through the gap (47) in the center of the winglet and serves as a squeezing part of the balloon. When the yarn end in the center hole of the bobbin is blown up, a large space (48) between the winglets is formed. )
It is formed so that the thread can easily pass through.

Further, in FIGS. 1, 2, and 4, the covers (19a) (19b)
(49) in the central part of the bobbin, that is, the part that covers the thread layer part of the bobbin
(50) is formed, the transparent portion is fixed to the window, and the state of the residual yarn during winding can be visually observed from the outside.

While the yarn is being wound by the above-mentioned device, the yarn to be unwound at high speed is in the covers (19a) and (19b) as shown in Figs. Without being scattered, as shown in FIG. 1, it is sucked and removed to the pipe (3) through the suction pipe (51) connected to the cover (20) covering the upper tensor portion. Further, when replacing the bobbin, the bobbins can be easily replaced by opening the covers (19a) and (19b) to the positions indicated by two-dot chain lines in FIG.

[Effect of device]

As described above, in the present invention, the cross-sectional area of the lower end opening of the cover formed by the covers (19a) and (19b) covering the periphery of the yarn supplying bobbin is made smaller than the cross-sectional area of the central portion of the cover, and the cover accompanying the yarn traveling is The inflow air from the bottom opening can be suppressed, and the inflow air into the cover can be efficiently sucked by the suction pipe without increasing the blower capacity of the suction pipe. Does not scatter. Furthermore, in the present invention, inside the cover,
Since a balloon guide that controls the balloon of the yarn unwound from the bobbin is attached, it is possible to suppress the increase in the unwinding tension of the yarn, and to prevent the fly cotton from scattering and the increase in the unwinding tension to be compact. Can be realized by various devices.

Further, the balloon guide (39) is covered with the covers (19a) (19
b) By being installed inside, the balloon of the yarn when being unwound from the yarn feeding bobbin does not randomly contact the inner wall of the cover, and the yarn is squeezed by the balloon guide (39) while traveling upward. Therefore, the cover can be prevented from scattering without disturbing the running and running of the yarn.
