Here, in drafting system 3, in order to stably transport sliver S, the fibre length of sliver S is longer, is more necessary to increase rear roller 11 and the interval of the 3rd roller 12 on the incline direction of inclined plane 41a and the interval between the 3rd roller 12 and intermediate calender rolls 13.In addition, because between intermediate calender rolls 13 and preliminary roller 14, sliver S transports under the state clamped by tengential belt 19a, 19b, how the length therefore regardless of the fiber of sliver S can stably transport, and need not change the interval of roller.
Therefore, in this embodiment, drawing roller unit 30a, 30b described above can move along inclined plane 41a.That is, in this embodiment by making drawing roller unit 30a, 30b move along inclined plane 41a, the interval of rear roller 11 and the 3rd roller 12 and the interval of the 3rd roller 12 and intermediate calender rolls 13 can be changed.
When the fibre length of sliver S is short, reduce the interval of rear winding drum 11b and the 3rd bottom roller 12b and the interval of the 3rd bottom roller 12b and middle bottom roller 13b simultaneously.When the fibre length of sliver S is long, increase the interval of rear winding drum 11b and the 3rd bottom roller 12b and the interval of the 3rd bottom roller 12b and middle bottom roller 13b simultaneously.
On the other hand, when make the 3rd bottom roller 12b near middle bottom roller 13b mobile drawing roller unit 30b, the 3rd bottom roller 12b moves to the direction leaving rear winding drum 11b.Therefore, in order to make rear winding drum 11b near the 3rd bottom roller 12b, be necessary than the mobile drawing roller unit 30a of drawing roller unit 30b the earth.
Otherwise, when make the 3rd bottom roller 12b away from middle bottom roller 13b mobile drawing roller unit 30b, the 3rd bottom roller 12b moves near the direction of rear winding drum 11b.In order to make rear winding drum 11b away from the 3rd bottom roller 12b, be necessary than the mobile drawing roller unit 30a of drawing roller unit 30b the earth.
From the foregoing, when the interval changing above-mentioned roller, than the 3rd bottom roller 12b (drawing roller unit 30b) the mobile rear winding drum 11b of the earth (drawing roller unit 30a).Therefore, by making the length d1 of through hole 41c longer than the length d2 of through hole 41d as described above in this embodiment, can enable the scope of drawing roller unit 30a movement can the wide ranges of movement than drawing roller unit 30b.
Further, if make drawing roller unit 30a, 30b move along inclined plane 41a like this, the interval of rear winding drum 11b and the 3rd bottom roller 12b and the interval of the 3rd bottom roller 12b and middle bottom roller 13b can be changed.But in this embodiment, drawing roller unit 30a, 30b are respectively except possessing bottom roller 11b, 12b and supporting except their support unit 51, also possess the motor unit 52 for driving bottom roller 11b, 12b.Therefore the weight of drawing roller unit 30a, 30b becomes heavy.And drawing roller unit 30a, 30b possess bottom roller 11b, 12b and the motor unit 52 of 2 drafting systems 3 respectively.Therefore, the weight of drawing roller unit 30a, 30b becomes heavier.In addition, this embodiment inclined plane 41a is inclined relative to horizontal about 60 °, and inclined plane 41a tilt angle alpha with respect to the horizontal plane becomes large.
Therefore, when changing the interval of drawing roller, be necessary to make drawing roller unit 30a, 30b of Heavy Weight move along the inclined plane 41a being inclined relative to horizontal angle large as described above.When making drawing roller unit 30a, 30b be moved upward along inclined plane 41a, operator applies large power to drawing roller unit 30a, 30b and moves it; When moving downwards, move it while support drawing roller unit 30a, 30b limit by large power.As a result, drawing roller unit 30a, 30b is made to move difficulty.
Especially in this embodiment because inclined plane 41a tilt angle alpha with respect to the horizontal plane becomes large (about 60 °), if therefore there is no balanced controls 43, then drawing roller unit 30a, 30b can slide downwards along inclined plane 41a under the effect of deadweight, drawing roller unit 30a, 30b are moved and becomes more difficult.
But upwards exert a force along inclined plane 41a because drawing roller unit 30a, 30b are as described above balanced mechanism 43 in this embodiment, therefore obtain can not along the balance of inclined plane 41a slide downward under Gravitative Loads for drawing roller unit 30a, 30b.
Therefore make drawing roller unit 30a, 30b move the suitable part of the little force produced with balanced controls 43 of required power in this embodiment, can easily make drawing roller unit 30a, 30b move.
Now, rotatable parts 46 and torsionspring 47 etc. is preferably made under Gravitative Loads, to want the size of the power of slide downward to be identical degree along the inclined plane 41a size of power that upwards counter extensioin roller unit 30a, 30b apply along inclined plane 41a with drawing roller unit 30a, 30b in balanced controls 43.That is, the force preferably making balanced controls 43 produce is the force with the gravitational equilibrium of drawing roller unit 30a, 30b.
If like this, the power that drawing roller unit 30a, 30b be upper to be acted on due to deadweight and the force that balanced controls 43 counter extensioin roller unit 30a, 30b apply balance, and operator and inclined plane 41a are applied to the power of drawing roller unit 30a, 30b abreast almost all for the movement of drawing roller unit 30a, 30b.Therefore, operator easily can move drawing roller unit 30a, 30b.And operator is at mobile drawing roller unit 30a, 30b and after determining position, can easily carry out tighting a bolt 71 is fixed in operation on installing plate 41.
