Outside the yarn feeding device 20, a blowing means 36, which is another feature of the present invention, is attached. FIG.
As shown in FIG. 7, the blower 36 includes a rotating ring 37, a motor fan 38 supported by the rotating ring 37, and a driving unit 39 for rotating the rotating ring 37.

In FIG. 4, a rotary ring 37 is disposed immediately below the tip of each horizontal member 16. The rotating ring 37 is supported so as to be rotatable on each of the support rollers 40 and 41. Each guide roller 42 on the rotating ring 37 regulates the vertical movement of the rotating ring 37. Each support roller 40 and each guide roller 42 are rotatably attached to respective brackets 43 and 44.
The brackets 43 and 44 are attached to the tip of each horizontal member 16. A geared motor 45 is attached to the bracket 43, and a support roller 40 is attached to the shaft of the geared motor 45 so as to penetrate the bracket 43. The drive of the geared motor 45 causes the rotation ring 37 to rotate due to friction with the support roller 40.

As shown in FIG. 5, the bracket 43 is provided with a limit switch 46 and a switch cam 47 which operates the limit switch and is movable along the rotating ring 37. A projecting member 48 for moving the switch cam 47 is attached to the rotating ring 37.

The outer peripheral side surface of the rotating ring 37 is shown in FIGS.
As shown in FIG. 2, at least one motor fan 38 is attached to face the yarn feeding device 20. The motor fan 38 is mounted on a bracket 50 via a vertical shaft 49 so as to be adjustable in the vertical direction. The bracket 50 is attached to the outer peripheral side surface of the rotating ring 37.

In the above-described configuration, the motor fan 38 of the air blowing means 36 moves together with the rotary ring 37. Alternatively, only the motor fan 38 can be moved. In this case, the rotating ring 37 for moving the motor fan 38 is fixed, and the geared motor 45 and the motor fan 38 are integrally attached. Then, the motor fan 38 together with the geared motor 45,
The fixed rotating ring 37 can be moved as a track.

Further, as another form of the blowing means 36,
Instead of the motor fan 38, it is also possible to use an air jet tube of Japanese Patent Publication No. 1-38999. This is at least one air ejection tube for ejecting air from the opening at the front end, in which a nozzle made of an elastic material is provided at the front end to perform a swing motion. Means for adjusting the swing angle of the swing motion may be provided. This air ejection pipe is connected to the yarn feeding device 20.
The air ejection pipe is attached to the rotating ring 37.
And the fiber waste generated in the yarn supplying device 20 is blown off.

As shown in FIGS. 8 and 9, a power supply method for causing the motor fan 38 installed on the rotating ring 37 to reciprocate includes a bearing housing 51, a hollow pipe 52, and a telescopic tube 53. Is done.

The bearing housing 51 is mounted via a shaft 54 mounted on the T-tube 25f. A pipe mounting member 55 is rotatably mounted on the bearing housing 51. A hollow pipe 52 is provided in the pipe mounting member 55 in the radial direction, and a vertical end of the hollow pipe 52 is suspended above the rotating ring 37. A vertical end of the hollow pipe 52 is
Is connected to one end. The other end of the telescopic tube 53 is a vertical axis 5
6 is attached to the upper part. The vertical shaft 56 is a bearing 57
And is attached to the side surface of the rotating ring 37 via a. Therefore, the wiring 58 to the motor fan 38 is guided from the upper center to the telescopic tube 53 via the hollow pipe 52, and then connected to the motor fan 38.

When the blower 36 is energized, the rotating ring 37 is rotated by the support roller 40 provided on the geared motor 45. When the rotation ring 37 makes one rotation, the projection member 48 comes into contact with the switch cam 47 to move it. The moved switch cam 47 activates the limit switch 46, whereby the geared motor 45 rotates in the reverse direction and rotates the rotating ring 37 in the reverse direction. Therefore, the motor fan 38 supported by the rotating ring 37 reciprocates in the circumferential direction as the rotating ring 37 rotates. At this time, the telescopic tube 53 and the hollow pipe 52 accommodating the wiring 58 around the bearing housing 51 follow the movement of the motor fan.

Since the motor fan blows fiber waste and the like generated from the yarn feeding device 20 toward the lower side of the filter 23, the fiber waste generated from the yarn feeding device 20 is applied to the filter 23 as shown in FIG. It is attracted and adheres to the inner wall of the filter.

FIGS. 10 and 11 are front views of a circular knitting machine provided with a device for collecting and removing fiber waste and the like according to the second and third embodiments of the present invention. Hereinafter, the second and third embodiments will be described, but the same components as those in the first embodiment will be denoted by the same reference numerals and description thereof will be omitted.

The second embodiment of the present invention shown in FIG. 10 is similar in overall configuration to the first embodiment. The second embodiment differs from the first embodiment in that the filter 60 rotates and that the tip opening 25a for sucking fiber waste and the like is fixed close to the inner wall of the filter 60. That is, the relationship between the filter 60 and the tip opening 25a is opposite to that of the first embodiment.

In the figure, the bottom of the filter 60 and the circular bottom plate 61 are separated, and the filter driving unit 2
6A allows the filter 60 to rotate.

When the motor fan 24 is energized, air is blown upward as in the first embodiment. As a result, the same effects as in the first embodiment can be obtained.

The third embodiment of the present invention shown in FIG. 11 differs from the second embodiment in that an intake / blowing means (for example, a motor fan 24) is housed in an intake cylinder 70 in the third embodiment. .

In the same figure, at the lower side of the filter 60, each stay 33 extending from the post 14 toward the machine center in such a direction as to blow the motor fan 24 in the direction of the arrow.
Supported by Outside the motor fan 24, there is provided an intake cylinder 70 that is suspended down to the top of the cylinder 7.

When the motor fan 24 is energized, air is blown upward as in the first and second embodiments. As a result, the same effects as those of the first and second embodiments can be obtained.

The above-described dust collecting / removing device is merely an example, and does not limit the present invention. Various changes, improvements, and modifications can be made within the scope of the claims. For example, the intake / blowing means may be housed in a filter, and the blowing direction may be downward. The suction nozzle is provided on the outer wall of the filter, and the fiber dust and the like accumulated on the outer wall are removed by a suction nozzle or the like.

[0051]

According to the present invention, the dust collecting device having the suction / blowing means 24 can quickly suck and remove fiber waste generated at the upper portion of the cylinder without scattering.

In a preferred embodiment, the rotating ring 3
By reciprocating 7, the blowing means 36 attached thereto blows fiber waste generated from the yarn feeding device toward the center of the machine while moving in the circumferential direction. Thus, the air flow in the vicinity of the intake / blowing means 24 attracts the air flow of the blowing means 36, so that dust such as fiber waste and dust can be efficiently collected.

Therefore, the present invention differs from the prior art,
A machine for collecting and collecting dust instead of simply blowing off fiber waste with a motor fan is provided in the knitting machine main body. This eliminates the need to individually shield the knitting machine body with a curtain-shaped one, and even if fiber waste etc. comes from an adjacent knitting machine or krill stand, the air of the air blowing means will not reach the knitting part until it reaches the knitting part. Since fiber waste and the like are collected along the flow, a high-quality knitted fabric can be obtained. In addition, since the number of stopped knitting machines is small, the operation rate is improved, and since there is no curtain-shaped shield, visibility in the knitting factory is improved and workability is improved. Furthermore, the amount of fiber debris floating in the air is reduced, and the environmental hygiene for the worker is kept good. Moreover, the structure is simple and inexpensive.
