BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a fly cleaning device incorporated in a spinning machine, and more particularly to a structure for mounting a front cover thereof.

[0002]

2. Description of the Related Art In general, in spinning machines such as a roving frame and a spinning frame, fly waste is generated from a roller part of a draft mechanism, and this deposits on members constituting the draft mechanism to form roving or yarn during spinning. There is a risk of being brought in and degrading quality. Therefore, as shown in FIG. 6, a duct 12 is provided below the draft mechanism along the longitudinal direction of the machine frame of the spinning machine, and a rotating impeller 13 is provided in the duct 12 over the entire length of the duct, and this is driven to rotate. As a result, a suction airflow is generated, and the openings 14, 24,
Through 25, the fly waste accumulated in each part of the machine and the fly waste generated during spinning are sucked into the duct 12 and removed by the filter 17 installed in the duct, so that the purified air is again removed. A method of returning to the room where the spinning machine is installed is adopted.

The front surface of the duct 12 is covered with a front cover 18 extending in the longitudinal direction of the machine frame having slits 15 and 16 as shown in FIG.
8 is fixed to upper and lower mounting plates 20 and 21 via brackets 19 arranged at appropriate intervals. Further, a top cover 22 is attached to the upper attachment plate 20, and forms the suction opening 14 in cooperation with an upper portion of the front cover 18.

[0004]

In this duct structure, since the bracket 19 is provided in the duct so as to cross the path of the fly waste from the opening 14 where the amount of fly waste to be sucked is particularly large, the fly waste is provided. But tended to get caught on the upper surface of this bracket, which gradually grew and eventually hindered the suction action.

SUMMARY OF THE INVENTION An object of the present invention is to solve the problems of the prior art and to provide a mounting structure for a front cover of a duct which has no undesired accumulation of fly waste in the duct.

[0006]

SUMMARY OF THE INVENTION An object of the present invention is to provide a spinning machine provided in a frame below a drafting mechanism of a spinning machine along a longitudinal direction of a machine frame and having a rotating impeller therein to perform a suction operation from a front surface. In the fly dust suction duct of the resulting cleaning device, a flow forming the front surface in the longitudinal direction of the duct.
The cover is provided on the frame of the spinning machine.
On the front of the roller stand provided at a fixed pitch
The end is screwed and fixed, and the lower part of the draft mechanism
This is achieved by a mounting structure of a front cover of a cleaning device in a spinning machine , wherein a suction opening is formed between the suction opening and the top cover .

[0007]

[Function] In the present invention, the wind sucked into the duct
In the suction path from the draft roller where the amount of cotton is particularly large
Since the bracket for mounting the front cover, which was conventionally used, was abolished and the front cover was screwed directly to the front of the roller stand to fix the position,
Obstacles that cross the suction path of fly waste from the draft roller section into the duct are eliminated, and a reduction in the suction cleaning effect due to the accumulation of fly waste is eliminated. Since the roller stand is located on the side of the draft roller, which is the path through which the fibers pass, it does not hinder the suction of fly waste.

Hereinafter, based on a preferred embodiment shown in the drawings,
The present invention will be described in more detail.

[0009]

1 is a side sectional view showing the structure of a first embodiment of the present invention applied to a ring spinning machine. A rotary impeller 1 is provided below the draft mechanism 11 along the longitudinal direction of the machine base.
3 is provided. The front cover 18 forming the duct 12 has slits 15 and 16 similar to those shown in FIG. The upper end of the front cover 18 is mounted on the roller stand 1 (FIG. 2) at a constant pitch to support the draft roller 11a of the draft mechanism.
) Is fixed by screws 2 as a receiving surface.

On the other hand, the lower end of the front cover 18 is fixed to a mounting plate 21 via a bracket 19 '. With this configuration , the top position of the top
Door formed by the head cover 22 and the front cover 18.
Conventionally, in the suction path from the raft roller portion, it is necessary to enter the duct 12 and
It is possible to omit the bracket 19 (FIG. 6) provided across the suction path of fly wool from, and it is possible to prevent the suction effect from being reduced due to the accumulation of fly wool.

FIG. 3 shows a second embodiment of the present invention. In this example, the shape of the lower part of the front cover 18 ′ is different from that of the first embodiment,
9 'is abolished and directly fixed to the lower mounting plate 21. Note that a horizontal slit is provided in the portion A of the front cover 18 ', through which fly cotton is sucked in by a suction airflow.

FIG. 4 shows a third embodiment of the present invention, in which a socket 3 as shown in FIG. 5 is mounted on the roller stand 1, and the upper portion of the front cover 18 "is fixed to the seat 3a of the socket 3 by screwing. Thereby, the position and posture of the opening 14 formed by the front cover 18 ″ and the top cover 22 can be adjusted to the optimum conditions for sucking fly waste.

[0013]

[Effect of the Invention] According to the present invention, a duct for cleaning fly waste is used .
Attaching the front cover that constitutes the suction opening in the longitudinal direction directly to the front of the roller stand of the draft roller
The amount of fly waste sucked into the duct is particularly large
The suction path from the draft roller unit, the path which interferes with the mounting bracket of the fly waste is omitted that enters into the duct
As a result, the effect of cleaning the duct due to the accumulation of fly waste on the bracket is prevented.
