[Example] Hereinafter, the present invention will be described in detail based on the accompanying drawings.

FIG. 1 is a front view showing a double knit circular knitting machine according to a first embodiment of the present invention. Reference numeral l indicates a bed, and a knitting section 2 is installed above the bed 1, and the cylindrical knitted fabric knitted by this knitting section 2 is wrapped around a winding Ha (not shown) below the knitting section 2.
It is rolled up into a flat shape. Bed 1 is supported by two legs 3.4. leg 3
, 4 are attached with gate members 5, 6.

A rectangular parallelepiped box 7 is attached to the side of the leg 3. As shown in FIG. 2, the box 7 is comprised of two chambers, a filter means accommodating section 8 and a preliminary filter accommodating section 9, which are separated from each other on the left and right sides. These housing portions 8 and 9 have double doors so that the front portions can be opened and closed.

A wire mesh 10, which occupies more than half of the filter means housing part 8, is attached to the filter means housing part 8. gold 1
The outside of the iQ10 is removably framed with a mesh-like fabric that serves as a filter 11, a W material 2 synthetic resin, and the like. The main purpose of providing the wire mesh 10 was to support the filter 11 and to prevent workers from getting close to the fan 12, which will be described later. You can also use For installation and removal of the filter 11, for example, Magic (trademark),
It is also possible to make it detachable by means of release means such as a button or a magnet. The mesh size of the filter 11 is preferably 1 to 3 mm.

In order to remove the fibrous debris etc. accumulated on the surface of the filter 11, it is possible to remove the framed filter 11 with the wire mesh attached, but it is more convenient to remove the filter 11 alone or the entire 10 frames of the filter support wire mesh. be.

Fiber waste can be removed by scraping it off by hand, rinsing it with water, or vacuuming it up. It is better to quantitatively replace the filter 11 with a new one.

A fan 12 is installed in the upper part of the filter means housing part 8, and as shown in FIG.
It is attached to the fan box 13. The fan box 13 is attached to the filter means housing part 8.

As shown in FIG. 5, the lower end of the fan box 13 is
It has an upwardly inclined portion 13a. An opening 13f can be provided in this inclined portion to adjust the air volume. By installing a slidable cover on the opening 13f,
Preferably, the size of the opening is adjustable.

There are two rectangular holes 13b on the upper side of the inclined part 13a for branching air into two directions, and two rectangular holes 13b on the upper surface of the 1000.
Holes 13d and 13e are bored at certain locations.

As shown in FIG. 3, each of the rectangular holes 13b and 13C communicates with a duct 14, 15, and their terminal ends are sealed by an obstruction.

However, it goes without saying that if there is no obstacle in front of the collecting end of the duct 14, 150, there is no problem in making it endless (see Fig. 11).

The ducts 14, 15 are installed directly below the bed l, and at least two holes 14a + 14b - 15a + 15b are bored in the upper surface of each duct 14, 15. As shown in FIG. 6, the holes 14a, 1
4b, 15a, 15b and the vertical pipe 17 in the hole of bed 1.
is inserted through the bed, and has a length such that its tip protrudes beyond the bed. The tip of the vertical tube 17 is bent in the direction of the knitting section 2, and the tip serves as an air outlet 18. Although the opening of the air outlet 18 is formed in a circular shape with the same diameter as the vertical pipe, it can also be formed into a flat-headed shape or have a smaller diameter than the vertical pipe.

According to this first embodiment, the air sent by the fan 12 passes through the vertical pipe 17 through the ducts 14 and 15 that are branched in two directions from the fan box 13, and enters the knitting section 2 from the air outlet 18. Air is blown towards the vicinity.

7 and 8 show a portion of a second embodiment of the present invention. Portions not shown are substantially the same as in FIG.

1 and 7, an outer cylinder support plate 23 is attached to the upper side of the bed 1 via three supports 20, 21, and 22. Outer cylinder support! 1123 includes a large gear 24 coaxially integrated with the machine shaft and an outer cylinder support plate 25 that supports the machine shaft.
is accommodated. Note that 26 is a top plate.

The difference between the second embodiment and the first embodiment shown in FIGS. 1 to 6 is that the air from the fan 12 is blown up from the fan box 13 and is sent to the bed and the outer cylinder support plate 2 through the bed l. Air is blown to the vicinity of the knitting section through a support 21 provided between the outer cylinder support plate 23 and from an air outlet 27 provided in the outer cylinder support plate 23. In this case, the air duct placed under the bed in the first embodiment of the invention is removed.

In order to improve the dust removal effect, the air outlet 27 is of a rotary type.

For this purpose, at least two ventilation ports 27 are attached to a rotary ring 28 on the lower surface of the outer cylinder support plate 23, as shown in FIG. 8, facing the knitting section 2. The rotating ring 28 connects the lower surface step of the outer cylinder support plate 23 and the outer cylinder support a1.
It is rotatably housed between plates 29 attached to 23. There are two rings 3 below the rotating ring 28.
0°31 is attached to the rotating ring 28. Inside ■
The rilling 30 is guided by a plurality of ball bearings 32 provided circumferentially. A roller chain 33 is attached to the outer diameter of the outer ring 31, and a sprocket wheel 3 meshes with the roller chain 33.
4 is attached to the motor 35. The motor 35 is attached to the outer diameter lower side of the outer cylinder support plate 23 via a motor support stand 36 .

According to this second embodiment, the air sent from the fan 12 is blown from the rotatable air outlet 27 installed in the outer cylinder support plate 23, and blows off fiber waste etc. that accumulate around the knitting part. be able to.

10 to 12 show a portion of a third embodiment of the present invention. Portions not shown are substantially the same as those in FIG. 8 or 9 of the second embodiment.

The difference between the third embodiment and the second embodiment shown in FIG. 8 or 9 is that the air outlet is not rotary, and an air duct 41 branched into two directions is arranged below the outer cylinder support plate 23. This air duct is provided with a rectangular air outlet 43.

In order to improve the dust removal effect, the direction of the air blowing port 43 can be adjusted artificially. For that purpose, a louver 44 is installed along each air outlet 43, as shown in FIG. In order to be able to adjust the wind direction, both ends of the louver 44 are equipped with bearings (such as spring parts) that also serve as locking means.
(not shown).

According to this third embodiment, the air sent by the fan 12 passes through the air ducts 41 and 42 provided below the outer cylinder support plate 23 via the support 40, and is provided at each air outlet. Air is blown by adjustable louvers,
It is possible to blow away fiber waste that accumulates around the knitting section.

In the first embodiment, the second embodiment, and the third embodiment, the fiber waste etc. blown away are removed from the filter means 11 either immediately or after drifting for a while on the air convection in the factory.
adsorbed and deposited on the outer surface of the

[Effect] According to the present invention, since the dust collector is attached to the knitting machine main body,
There is no need for a space to install the dust collector in a location separate from the knitting machine body as in the previous patent application, and since the dust collector is installed near where fiber waste is generated, it is possible to remove fiber waste, etc. Dust collection effect is improved.

Further, in the first embodiment of the present invention, fiber waste is blown away by blowing air blown by a fan to the knitting section through a duct, and in the second embodiment of the present invention, air blown by a fan is blown to support the knitting section. In the third embodiment of the present invention, air is blown from a rotatable air outlet placed on the outer cylinder support plate through the outer cylinder support plate and blows away fiber waste, etc. that accumulates around the knitting part. The air blown by the fan can be blown through the support and the air duct from the air outlet louver of the air duct to blow away fiber waste that accumulates around the knitting part, thereby achieving the Ishimishima effect.
