 Hereinafter, the present invention will be described with reference to the illustrated embodiments. The present invention will be described by giving the same reference numerals to the same components as those of the above-described specific example. 1 to 5, reference numeral 1 is a knitting needle cylinder provided with a large number of cylinder needles 1a rotatably fitted in a machine frame (not shown) of a circular knitting machine. A dial yoke 2 is provided integrally with a cylindrical cylindrical body (holder) 3 on a machine frame (not shown) immediately above, and a disc-shaped dial is provided on a lower portion 3a of the cylindrical body 3. The cam plate 4 is mounted horizontally. A well-known yarn carrier 5 is provided on the outer peripheral portion 4a of the dial cam plate 4 so as to supply the knitting yarn Y to the cylinder needle 1a. Each of the dial cams 6a and 6b is provided so as to operate a dial needle 11, which will be described later. Further, a pair of upper and lower bearings 7 are provided on the upper and lower portions 3a and 3b of the cylindrical body 3, and a rotary cylinder 8 is rotated on both bearings 7 in synchronization with the knitting needle cylinder 1. It is rotatably mounted on the shaft. Further, a dial 10 integral with the dial plate 9 is horizontally provided on the lower portion 8a of the rotary cylinder 8 so as to be located below the dial cams 6a and 6b. Is provided so that a large number of dial needles 11 can slide back and forth in the radial direction by the dial cams 6a, 6b. Moreover, the dial needles 11 cooperate with the cylinder needles 1a to make a yarn carrier. The knitted fabric f is knitted with the knitting yarn Y from No. 5. A dial gear 12 is attached to the upper portion 8b of the rotary cylinder 8 so that the rotary gear 8 rotates in synchronization with the knitting needle cylinder 1.

As described above, the dial cams 6a and 6b, the dial plate 9, the integral dial 10, the large number of dial needles 11 and the like constitute the dial device I.

On the other hand, as shown in an enlarged view in FIGS. 1 and 3, a pair of support fittings 40 are vertically provided on the back surface of the flange portion 2b of the dial yoke 2. A fixed ring 41, which is divided into two, is provided around the dial yoke 2 so as to be disassembled by a pair of upper and lower connecting members 42a and 42b having an arc shape. A pair of upper and lower peripheral grooves are formed on the outer periphery of the fixing ring 41, and bearing seats 43 are attached to the peripheral grooves so as to reduce friction. Further, on the outer circumference of each of the bearing seats 43, a rotating ring 45 divided into two is provided so as to be disassembled by being located around the fixed ring 41 by a pair of upper and lower connecting members 46a and 46b having an arc shape. The rotating ring 45 is reciprocally fitted around the fixed ring 41 via the bearing sheets 43. Furthermore, a ring-shaped rack 47 is fixedly attached to the outer periphery of the rotating ring 45. This rack 47 mounts the rotating ring 45 on the fixing ring 41 via each bearing seat 43. It is provided so as to reciprocate around. A holding metal fitting 48 is vertically provided on the back surface of the flange portion 2b immediately above the rotating ring 45, and a driving motor 49 such as a pulse motor is directly attached to the holding metal fitting 48. It is installed horizontally so as to rotate in the opposite direction. Further, an output shaft 49a of the drive motor 49 is mounted with a pinion 50 so as to mesh with the rack 47, and the drive motor 49 passes through the pinion 50 and the rack 47 which meshes with the pinion 50. The rotating ring 45 is reciprocally rotated around the fixed ring 41.

On the other hand, a plurality of flexible air supply pipes 51 are connected to the rotating ring 45, for example, by nipples 52 according to the number of the yarn carriers 5 attached. The pipe 51 is connected to a supply source of compressed air (not shown). Further, jet nozzles 53 are connected to the rotary ring 45 by, for example, nipples 54 according to the number of the yarn carriers 5 attached, and the jet nozzles 53 are compressed from the air supply pipe 51. Air is blown onto the yarn carrier 5 so that it is bent so as to remove the cotton wool.

The operation of the present invention will be described below. Therefore, when the drive motor 49 is driven to rotate in the forward and reverse directions during knitting, the pinion 50 of the output shaft 49a fixes the rotating ring 45 via the rack 47 which meshes with the pinion 50 via the bearing seats 43. It reciprocates around the ring 41 at a desired speed.

On the other hand, the compressed air from the compressed air supply source is injected to the yarn carrier 5 through the air supply pipe 51 and the air injection nozzle 53, and the cotton wool adhering to the yarn carrier 5 is removed to thread the yarn. The operability is improved.

In this way, the present invention removes cotton wool from yarn carriers, dust, etc., generated in the yarn supplying section of the circular knitting machine from the yarn carrier 5 to prevent the cotton wool from accumulating around the device. We are trying to improve the sealing efficiency and operating efficiency.

Although the present invention has been described with respect to the structure in which the rotary ring 45 is reciprocally rotated by the rack 47 and the pinion 50, the crank mechanism and the cam, for example, may be used without departing from the scope of the present invention. The design can be freely changed so that the rotating ring 45 can be reciprocally rotated by the mechanism.

【The invention's effect】

 As described above, according to the present invention, the dial yoke of the dial device is provided with the fixing ring, the bearing seat is attached to the outer circumference of the fixing ring, and the turning ring can be reciprocally turned on the outer circumference of the bearing seat. Since the air supply pipe is connected to the rotating ring, the injection nozzle is connected to the rotating ring, and the compressed air from the air supply pipe is injected to the yarn carrier to remove the cotton wool. Not only can compressed air be prevented from leaking even if it is used for a long period of time, but it is also possible to reduce the amount of compressed air consumed by efficiently treating the fly and improve the sealing efficiency and operating efficiency. It has an excellent effect that it can be installed and used on a knitting machine as it is.
