Direction along the axially parallel with front bottom roller 28 in spinning machine 1 configures elongated axle 68.Each parts such as tension rail (omitting in drawing) that are used for producing tension force on bottom side tengential belt 27 are arranged on axle 68.Axle 68 is bearing in the framework 6 of spinning machine 1 mutually independently with fixed frame 67.
As shown in Figures 5 and 6, tengential belt fork (the apron fork) 99 as tengential belt position change parts is arranged on axle 68 via the frame 69 that traverses.Tengential belt fork 99 has 2 protuberances.Under the state inserting between these 2 protuberances at bottom side tengential belt 27, tengential belt fork 99 is fixed on and traverses on frame 69.The frame 69 that traverses can move by the length direction along this axle 68 with respect to axle 68, is connected on the drive unit that traverses (not shown).
By driving drive unit tengential belt fork 99 length directions along axle 68 that traverse, move back and forth ，Shi bottom side tengential belt 27 and traverse in the direction of the direction of principal axis almost parallel with middle bottom roller 26.，Shi bottom side tengential belt 27 always changes with the place that contacts of fibre bundle 8 thus, can prevent concentrated wear, the growth life expectancy of bottom side tengential belt 27.
Catch bar 31 is fixed on the supporting arm 29 that is disposed at drafting system 7 downstreams (downstream of the throughput direction of fibre bundle 8) as shown in Figure 3.Supporting arm 29 roughly configures towards above-below direction in the short transverse of board, open end spinning apparatus 9 portion fixed thereon.Supporting arm 29 can form rotationally centered by the fulcrum 30 that is configured in its bottom.By catch bar 31, follow the rotation of supporting arm 29 to move, can remove contacting of body flange 100 and front bottom roller 28.In addition, the details aftermentioned of action is removed in relevant this contact.
As shown in Figure 3, in the spinning operation of spinning machine 1, a plurality of drawing roller that comprise front bottom roller 28 are driven in rotation respectively, and stretching sliver 13 generates fibre bundle 8 and carries to open end spinning apparatus 9.When running well, by the transmission lever 71(bar contact site 96 of the elastic force application of force of the 1st torsionspring 94) make body flange 100 near front bottom roller 28 ground to flange bearing bar 70(flange side operand 98) application of force.As a result, flange bearing bar 70 and transmission lever 71 one rotations, the roller contact-making surface 101 that makes to be arranged on the body flange 100 on clamp support 72 contacts with the outer peripheral face of front bottom roller 28.Under this state, body flange 100 contacts with the outer peripheral face of front bottom roller 28 with roughly certain pressure, and the foreign matters such as cotton sugar, flyings and rubbish from sliver 13 grades are attached on bottom roller 28 are scraped down by body flange 100.
Then with reference to Fig. 6 and Fig. 7, the action contacting of removing body flange 100 and front bottom roller 28 is described.If produce broken yarn etc. in the running of spinning machine 1, the spinning that open end spinning apparatus 9 carries out is stopped, and the drawing-off that drafting system 7 carries out is also stopped.On the supporting arm 29 of each spinning unit 2, be connected with actuator (not shown), not shown control part makes the actuator action of the spinning unit 2 that meets.As a result, supporting arm 29 rotates centered by fulcrum 30 as Fig. 7.That is the direction that, supporting arm 29 leaves drafting system 7 along open end spinning apparatus 9 is rotated.Now, catch bar 31 leaves flange bearing mechanism 63 ground and supporting arm 29 one move.
Thus, catch bar 31 end contacts with transmission lever side operand 97, by this transmission lever side operand 97, gives transmission lever 71 effect extruding forces.Under this extruding force effect, transmission lever 71 is rotated along the direction that overcomes the elastic force of the 1st torsionspring 94.With the flange bearing bar 70 that the 2nd torsionspring 95 is connected with transmission lever 71, follow the rotation rotationally of transmission lever 71, body flange 100 in the past bottom roller 28 leaves.
Flange bearing bar 70 action such and catch bar 31 is rotated linkedly, and the moment of having rotated the angle of regulation at flange bearing bar 70 makes limiting part 74 upper end contact with flange bearing bar 70, stops further rotation.From this state, even if make transmission lever 71 along the direction rotation that body flange 100 is continued leave front bottom roller 28, the displacement of this transmission lever 71 is also absorbed by the strain of the 2nd torsionspring 95, and flange bearing bar 70 does not rotate.
This example forms as described above, and cleaning device 61 possesses the body flange 100 that can arrange contiguously with the outer peripheral face of front bottom roller 28.Due to 101 one-tenth shapes along the outer peripheral face of front bottom roller 28 of roller contact-making surface of body flange 100, so body flange 100 contacts with 28 of front bottom rollers.By body flange 100, contact with 28 of front bottom rollers, the power that body flange 100 is subject to when body flange 100 has been expressed to front bottom roller 28 is dispersed to whole roller contact-making surface 101.Thus, suppress 100 some concentrated wears of body flange, can improve the mar proof of body flange 100.
Roller contact-making surface 101 by body flange 100 is practised physiognomy and is contacted with the outer peripheral face of front bottom roller 28, the adding to shake and be not a little concentrated in a place and be dispersed of roller contact-making surface 101 when front bottom roller 28 has rotated, can reduce respectively to add the vibration at a place of shaking.Thus, can suppress the generation that body flange 100 vibrates the noise causing.
Even if make the thickness of body flange 100 for also can suppress the thickness of the vibration of body flange 100 in the situation that front bottom roller 28 has rotated.Thus, even in the situation that front bottom roller 28 has rotated, also can suppress the generation that body flange 100 vibrates the noise causing.
Can groove 102 on the roller contact-making surface 101 air escape place between the roller contact-making surface 101 of body flange 100 and the outer peripheral face of front bottom roller 28 will be arranged on.Thus, the pressure oscillation that enters the air between body flange 100 and front bottom roller 28 can be reduced, the generation that air pressure changes the noise causing can be reduced.
By confirming that the degree of depth of groove 102 can easily judge the state of wear of roller contact-making surface 101.Thus, can easily hold the replacing period of body flange 100.
Make groove 102 on roller contact-making surface 101, extend into V font, by the direction from closure one side of V font towards an open side shifting towards the outer peripheral face that becomes front bottom roller 28 of V font groove 102.According to this structure, when the air in groove 102 is followed front bottom roller 28 in rotary moving, air is not concentrated in the closed side part of V font in groove 102, can make air towards the end diffusion of the open sides of the V font in groove 102, air can be discharged to outside in the open sides end of V font from groove 102.Thus, can further reduce the generation of the noise that the pressure oscillation of air causes.
The drawing roller in a plurality of drawing roller Zhong， downstream in being arranged on drafting system 7 is than other drawing roller High Rotation Speed.Therefore,, by the body flange 100 of excelling in abrasion resistance and the front bottom roller 28 of High Rotation Speed are contacted, can reduce the frequency of safeguarding of drafting system 7.In the situation that body flange 100 is contacted with drawing roller, follow the increase noise of the rotating speed of drawing roller also to become large.Therefore,, by making to be provided with the body flange 100 of groove 102 and the front bottom roller 28 of High Rotation Speed contacts, can effectively suppress the noise that drafting system 7 produces.
