This is the cause of needle damage and flaw.

Many inventions are known for removing this fibrils.

This type of device has an air ejecting plate having a tip opening at the position where fibrosis occurs. Usually, several air blowing pipes are used in one circular knitting machine, and they are used to blow fiber fibers wrapped in a specific part while rotating in the same direction or in the opposite direction to the rotating cylinder. As an example of such a prior art, invention of Unexamined-Japanese-Patent No. 52-33705 is mentioned. The present invention is to rotate the air ejection pipe and the rotating cylinder in the reverse direction, the tip opening of the air ejection pipe is the height of the knitting portion The invention is that the air ejection pipe and the rotation cylinder rotates in the reverse direction, the end opening of the air ejection pipe is knitted The negative direction is directed in the direction of the cylinder rotation, and the jet air is jetted in the same direction as the running direction.

In the prior art, since the directions of rotation of the air ejection pipe and the rotation cylinder are opposite, the air ejection pipe is rotated while blowing the knitting portion at an extraordinary speed. As a result, the jam at each site is inadequate. In the more general prior art, the air discharge pipe rotates at the same speed in the same direction as the rotary cylinder. Even in this prior art, when the high speed operation is performed, the rotational speed of the air jet pipe is somewhat overspeed. A further drawback of this prior art is that the air ejection pipe and the rotating cylinder are somewhat overspeed in the same direction. In addition, the drawback of this prior art is that since the air ejection pipe and the rotating cylinder rotate at the same speed in the same direction, only one place is damped against rotation with the cinder part, the cincher cap part, and other cylinders of the knitting part. It's useless.

The present invention has been made to solve the above drawbacks, and an object of the present invention is to provide a vibration damping device for a circular knitting machine having an excellent vibration damping effect.

It is a specific object of the present invention to provide a vibration damping device for a circular knitting machine equipped with means for rotating the air ejection pipe in the same direction as the rotational direction of the rotary cylinder.

The vibration suppression apparatus of the present invention which achieves the above object has at least one air ejection tube rotating in the same direction as the rotary cylinder and ejects the air from the front end of the air ejection tube. A deceleration means for slowing down the rotational speed is provided. Preferably, the deceleration means is a plurality of bevel gears.

EXAMPLE

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. In the circular knitting machine shown in FIG. 1, the knitting part 5 is provided above the bed 4 supported by the three legs 1, 2, and 3. As shown in FIG.

As shown in FIG. 2, the knitting part 5 is provided with the cylinder attachment 6 and the jumper part 7 with the yaw carrier part 8, as shown in FIG. In the cylinder needle portion 6, the needle needle is free to slide in the vertical direction along a plurality of needle grooves formed on the outer circumference of the rotary cylinder 15. The cylinder portion rotates at the same speed as the gearing (not shown) provided in the lower portion of the cylinder. In the shinker portion 7, the siker is a sliding material in the radial direction along a plurality of the siker grooves formed in the siker dial. A thinner cap constituting a part of the thinner portion 7 is supported by a lower support 9 supported on the bed 4. In the Ya'an Carrier section 8, the Ya'an Carrier must die suddenly. This yaan carrier part 8 is attached to the yaan carrier ring 11 via the yaan carrier ring support 10 supported on the said jumper part 7. In the center of the circular knitting machine, the first fixing plate 13 serving as one part of the air passage 12 is located. The air passage 12 is connected to a pressure side air source (not shown).

The upper end of the first fixing plate 13 is fixed to the joint 14. The lower end extends to the bearing housing 23 which will be described later. The vertical position of the bearing housing 23 is slightly above the upper end of the rotating cylinder 15 constituting the cylinder portion 6. The joint 14 is supported by three horizontal members 16, 17, 18 extending radially. These horizontal members 16, 17, 18 are connected to three posts 20, 21, 22 established on the bed 4 by different joints 19, 19. It is.

In addition, when only the air introduced from the air passage 12 in the fixed plate 13 is insufficient, the second fixing plate 13a can be provided for air supplement.

The second fixing plate 13a connects between the compressed air source (not shown) and the bearing housing. Under the bearing housing 23, the rotating shaft 24 engaged with it extends to the lower side of the bed 4. At the lower end of the rotating shaft 24, a weaving width adjusting section 26 for adjusting the weaving width of the cylindrical weaving 25 formed by the knitting section 5 is disposed. This knitting width adjusting section 26 is free to rotate at the same time as the bearing housing 23.

In addition, a winding portion 27 is disposed just below the knitting width adjusting portion 26 to wind up the texture to the required length. This winding 27 is rotatable via the connecting rod 28 by the gearing (not shown) slidably provided in the bed 4. As shown in FIG. 3, the bearing housing 23 has a fixed lid portion 23a and a bottom portion 23c rotatable in the same manner as the rotatable main body tube portion 23b. A connecting elbow 30 of the connecting plate 29 and the second fixing plate 13a connected to the lower end of the fixing plate 13 is respectively inserted into the lid portion 23a. At least one opening part is provided in the main body pipe part 23b. In this embodiment, two of the first opening 31 and the second opening 32 are provided. In the bottom part 23c, the upper end 33 of the rotating shaft 24 is penetrated. Air guided to the fixed plate 13 and the connecting pipe 29 flows into the lower annular air passage 34. At least one hole (three in the drawing) 35 is laid in the lower portion of the connection pipe 29 (see FIG. 5), and air passes through the hole 35. The energy flowing into the lower annular air passage 34 is ejected in the vicinity of the knitting portion 5 through the first opening 31 and the first air ejection pipe 36 connected to the first opening (FIG. 2).

Air guided to the second fixing plate 13a flows into the upper annular air passage 37 through the connecting elbow 30. Here again, the air is blown off the upper portion of the knitted portion through the second opening 32 and the second air blowing pipe 39 connected to the second opening via the elbow 38 (see FIG. 1).

In FIG. 1, the knitting injured portion is constituted by an IRO tape type positive feeding machine 40 and a thread cutting accident detection device 41.

On the other hand, the rotational force of the rotation shaft 24 rotates the first bevel gear 42 fixed to the rotation side upper end 33. However, because of the lower bearing 43 attached to the upper end of the rotary shaft 33, the rotational force does not rotate the main tube portion 23b of the bearing housing. The rotational force of the first bevel gear 42 is transmitted to the vertical second bevel gears 44 engaged with each other to rotate it. The second bevel gear 44 is attached to the main tube portion 23b with a rotating material. Since the third bevel gear 45 engaged with the second bevel gear 44 is stopped, the rotational force of the second bevel gear 44 rotates the main tube portion 23b.

The third bevel gear 45 is fixed to the lower end of the connecting pipe 29. These bevel gears 42, 44 and 45 serve as deceleration mechanisms by adjusting dimensions. It is preferable that the main body tube part 23b of the bearing housing is at a 1/2 speed in the same direction as the rotational direction of the rotation shaft 24. The rotational force of the main body tube portion 23b is not transmitted to the connecting section 29 and the lid portion 23a of the bearing housing due to the upper bearing 46 provided between the main body tube portion 23b and the connecting tube 29. . Therefore, these parts remain stationary. The damping by air can be performed not only from the center of the rotating cylinder toward the knitting portion and the upper portion of the knitting portion, but also from the outside of the rotating cylinder toward the knitting portion. 6 and 7 show the case of vibration damping toward the knitting portion from the outside of the rotation cylinder. In FIG. 6, the air guided through the third fixing plate 47 from the compressed air source (not shown) is ejected directly above the siker portion 7 via the third air ejecting plate 48.

In FIG. 7, the air guided through the fourth fixing tube 49 from the compressed air source (not shown) is ejected at an oblique upper side of the cinch section 7 via the fourth air ejecting tube 50. .

As described above, four air ejection pipes are used in this embodiment.

That is, two (first air ejection pipe 36 and second air ejection plate 39) from the center of the rotation cylinder toward the knitting portion and the upper portion of the rotation cylinder toward the knitting portion (third air A blowing pipe 48 and a fourth air blowing pipe 50). It is, of course, possible to increase or decrease the number of air ejection pipes. As in this embodiment, when the number of air ejection pipes is four, the air pressure is weakened, and the damping effect is impaired. In order to eliminate this drawback, the present embodiment uses a timer and a solenoid valve mechanism to intermittently supply air to each of the four air ejection pipes.

8 and 9 show a control panel 53 which is a timer 51 and a solenoid valve 52. The compressed air guided through the intake port 54 at the compressed air source (not shown) is intermittently allocated to the four fixed tubes by the solenoid valve 52 controlled by the timer 51. The timer 51 and the solenoid valve 52 can employ | adopt a well-known thing.

10 is an example of a solenoid valve mechanism. When energized by the timer 51, as shown in FIG. 10A, the spool valve 55 moves to the left, and the compressed air blown in by the intake port 54 is sent out to 13 which is one of the fixed plates. However, at the time of non-energization, as shown in FIG. 10B, the spool valve 55 moves to the right side, and compressed air is not sent to 13 which is one of the fixed plates. The same applies to the other three fixing plates 13a, 47, and 49.

According to the present invention, since the air ejection pipe rotates in the same direction as the rotation cylinder, the forward effect is superior to the prior art. In addition, the above description relates to an embodiment of the present invention, and various other improvements, modifications, and changes are possible within the scope of the claims.
