Contact site 64 from root 61 on left and right directions than beginning below installing plate 41 part a little in the outer part, extend with the direction of inclined plane 41a quadrature on the edge, the face of the downside of the incline direction of inclined plane 41a contacts with the ejection part 46a of rotatable parts 46.Thus, drawing roller unit 30a is balanced mechanism 43 along inclined plane 41a (with the opposite direction of moving direction under the deadweight effect) application of force upwards at contact site 64.So drawing roller unit 30a can be in the balance of the effect lower edge inclined plane 41a that conducts oneself with dignity to lower slider through being balanced mechanism's 43 application of forces acquisition.
In addition; As stated; 30a, 30b are not configured in and are limited parts 44a under the state on the 41a of inclined plane and limit it and move ejection part 46a in the drawing roller unit; Remain on the position shown in Fig. 6 (b), but be configured to inclined plane 41a when going up as drawing roller unit 30a, 30b, this position become can with contact site 64 position contacting (can ejection drawing roller unit 30a, 30b position).
Drawing roller unit 30b is the unit with structure identical with drawing roller unit 30a, and the ratio that is configured in inclined plane 41a has disposed the position of drawing roller unit 30a and leaned on the position in downstream.Wherein, drawing roller unit 30b uses the unit that forms with the parts of drawing roller unit 30a identical type, be configured on the 41a of inclined plane towards opposite with drawing roller unit 30a.
And in being configured in the drawing roller unit 30b of drawing roller unit 30a downside, bolt 71 runs through through hole 61a and the insertion of through hole 41d ground from through hole 61a one side.When tighting a bolt 71 the time, drawing roller unit 30b is fixed on the installing plate 41 (frame 40) through bolt 71 and nut 72.And when unclamping bolt 71, that removes drawing roller unit 30b pass through bolt 71 and nut 72 fixing on the installing plate 41, thereby drawing roller unit 30b can 41a moves along the inclined plane in through hole 61a and the opposed scope of through hole 41d.
As stated, because the length d 2 of through hole 41d is shorter than the length d 1 of through hole 41c, so the drawing roller unit 30b scope that can the move narrow range that can move than drawing roller unit 30a.
And in drawing roller unit 30b, the rotating shaft 12b1 through the 3rd bottom roller 12b inserts among the through hole 62b of the protuberance 62a that constitutes roller support 62, and the 3rd bottom roller 12b rotation freely is bearing on the roller support 62.
And, with drawing roller unit 30a in the drawing roller unit of opposite configuration 30b, the lug boss 63a of motor support 63 is opposite with drawing roller unit 30a, and is outstanding to the front lower place from root 61.Thus, the 30a protrusions 63a of portion is side-prominent to opposite with drawing roller unit 30b one on the incline direction of inclined plane 41a in the drawing roller unit.And the motor unit 52 that is bearing on the lug boss 63a also is configured in a side opposite with drawing roller unit 30b.On the other hand, in drawing roller unit 30b, lug boss 63a is side-prominent to opposite with drawing roller unit 30a one on the incline direction of inclined plane 41a.And the motor unit 52 that is bearing on the lug boss 63a also is configured in a side opposite with drawing roller unit 30a.Therefore, between drawing roller unit 30a and drawing roller unit 30b, do not have lug boss 63a or motor unit 52, can on the incline direction of inclined plane 41a, closely dispose rear winding drum 11b and the 3rd bottom roller 12b.
Here, in drafting system 3, for conveyance sliver S stably, the fibre length of sliver S is long more, just is necessary to increase back roller 11 and the interval of the 3rd roller 12 between the interval on the incline direction of inclined plane 41a and the 3rd roller 12 and intermediate calender rolls 13 more.In addition, because in the conveyance under of sliver S between intermediate calender rolls 13 and the preliminary roller 14,, need not change the interval of roller therefore regardless of the conveyance how stably of the length of the fiber of sliver S by the state of tengential belt 19a, 19b clamping.
Therefore, drawing roller unit 30a, 30b can move along inclined plane 41a as stated in this example.That is, 41a moves along the inclined plane through making drawing roller unit 30a, 30b in this example, can change the interval of back roller 11 and the 3rd roller 12 and the interval of the 3rd roller 12 and intermediate calender rolls 13.
Under the short situation of the fibre length of sliver S, dwindle 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.Under the long situation of the fibre length of sliver S, 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, make the 3rd bottom roller 12b near middle bottom roller 13b move under the situation of drawing roller unit 30b, the 3rd bottom roller 12b moves to the direction of leaving rear winding drum 11b.Therefore, in order to make rear winding drum 11b, be necessary to move drawing roller unit 30a than drawing roller unit 30b the earth near the 3rd bottom roller 12b.
Otherwise, make the 3rd bottom roller 12b away from middle bottom roller 13b move under the situation of drawing roller unit 30b, the 3rd bottom roller 12b moves to the direction near rear winding drum 11b.In order to make rear winding drum 11b, be necessary to move drawing roller unit 30a than drawing roller unit 30b the earth away from the 3rd bottom roller 12b.
Know from above-mentioned, in the interval that changes above-mentioned roller, move rear winding drum 11b (drawing roller unit 30a) than the 3rd bottom roller 12b (drawing roller unit 30b) the earth.Therefore, grow the wide ranges that the scope that drawing roller unit 30a can be moved can move than drawing roller unit 30b through the length d 1 that as above-mentioned, makes through hole 41c than the length d 2 of through hole 41d in this example.
And 41a moves along the inclined plane if make drawing roller unit 30a, 30b like this, can change 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.But drawing roller unit 30a, 30b except possessing bottom roller 11b, 12b and supporting their support unit 51, also possess the motor unit 52 that is used for driving bottom roller 11b, 12b respectively in this example.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 example inclined plane 41a is inclined relative to horizontal about 60 °, and 41a tilt angle alpha with respect to the horizontal plane in inclined plane becomes big.
Therefore, when changing the interval of drawing roller, be necessary as above-mentioned, to make the drawing roller unit 30a of Heavy Weight, 30b to move along being inclined relative to horizontal the big inclined plane 41a of angle.Make drawing roller unit 30a, 30b along inclined plane 41a to above when moving, the operator applies big power and moves it for drawing roller unit 30a, 30b; When moving downwards, the limit moves it with big power support drawing roller unit 30a, 30b limit.As a result, make drawing roller unit 30a, 30b move difficulty.
Especially in this example because 41a tilt angle alpha with respect to the horizontal plane in inclined plane becomes big (about 60 °); If therefore there are not balanced controls 43; Then drawing roller unit 30a, 30b can slide downwards at the effect lower edge inclined plane 41a of deadweight, drawing roller unit 30a, 30b are moved become more difficult.
But, in this example since as above-mentioned drawing roller unit 30a, 30b be balanced mechanism 43 along the inclined plane 41a application of force that makes progress, so drawing roller unit 30a, 30b obtain not can be in deadweight effect lower edge inclined plane 41a to the balance of lower slider.
Therefore make in this example drawing roller unit 30a, 30b move needed power little the suitable part of the application of force that produces with balanced controls 43, drawing roller unit 30a, 30b are moved.
At this moment, preferably make rotatable parts 46 and torsionspring 47 grades in the balanced controls 43 41a make progress along the inclined plane that inclined plane 41a will be identical degree to the size of the power of lower slider in deadweight effect lower edge for size and drawing roller unit 30a, the 30b of the power that counter extensioin roller unit 30a, 30b apply.That is, preferably make the application of force that balanced controls 43 produce for the application of force of the gravitational equilibrium of drawing roller unit 30a, 30b.
If like this; The application of force balance that drawing roller unit 30a, the last power that acts on owing to conducting oneself with dignity of 30b and balanced controls 43 counter extensioin roller unit 30a, 30b apply, the power that operator and inclined plane 41a impose on drawing roller unit 30a, 30b abreast almost all is used for moving of drawing roller unit 30a, 30b.Therefore, the operator can easily move drawing roller unit 30a, 30b.And the operator is at mobile drawing roller unit 30a, 30b and after having determined the position, and 71 operations that are fixed on the installing plate 41 can easily tight a bolt.
And; The adjustment of the position of drawing roller unit 30a, 30b is through clipping between 2 roots 61 of drawing roller unit 30a, 30b under the state that has with the liner of the corresponding length of kind of fiber constituting respectively, and 41a moves and carries out along the inclined plane to make drawing roller unit 30a, 30b.Because the operator can easily move drawing roller unit 30a, 30b under these circumstances, therefore can easily carry out the position adjustment of drawing roller unit 30a, 30b.
And; In this example, adopt rotatable parts 46 and to the torsionspring 47 of rotatable parts 46 application of forces, as being used for the structure of balanced controls 43 of counter extensioin roller unit 30a, the 30b application of force with ejection ejection part 46a on the contact site 64 of support unit 51.Utilize this structure, in this example, can more easily form balanced controls 43.
And 30a, 30b are not configured under the state on the 41a of inclined plane through ejection part 46a and are maintained at the top position contacting with limiting part 44a in the drawing roller unit by the rotatable parts 46 of torsionspring 47 application of forces, and restriction being moved further from this position.If rotatable parts 46 are positioned at this position, in the time of on drawing roller unit 30a, 30b being configured to inclined plane 41a, contact site 64 contacts with ejection part 46a.Therefore, before being configured to drawing roller unit 30a, 30b on the 41a of inclined plane, need not make rotatable parts 46 against the application of force of torsionspring 47 move to ejection part 46a can with contact site 64 position contacting.Thus, the operator becomes easy with the operation that drawing roller unit 30a, 30b are configured on the 41a of inclined plane.
In addition, though be necessary to change the position change of consistently carrying out top roller 11a, 12a with the position of bottom roller 11b, 12b, outer peripheral face is compared in light weight by the top roller that resin material constitutes with the bottom roller that is made up of metal material at least.And top roller is to be driven in the driven voller that the rotation of bottom roller is rotated, and not having does not in the drawings have supporting motor on the parts of supporting top roller of expression.Therefore, top roller is compared with bottom roller and can easily be carried out the change of its position.
Below, the variation that this example has been applied all changes is described.But,, suitably omit its explanation for the structure identical with this example.
Though in the above-mentioned example, drawing roller unit 30a, 30b possess bottom roller 11b, 12b and the motor unit 52 of 2 drafting systems 3 respectively, the quantity of the roller that drawing roller unit 30a, 30b are possessed is not limited thereto. Drawing roller unit 30a, 30b also can possess 1 perhaps bottom roller 11b, 12b and the motor unit 52 of the drafting system 3 more than 3 respectively.
And though drawing roller unit 30a, 30b possess the motor unit 52 that is used for driving bottom roller 11b, 12b respectively in the above-mentioned example, motor unit 52 also can be arranged with drawing roller unit 30a, 30b branch.
And though above-mentioned example medium dip face 41a tilt angle alpha with respect to the horizontal plane reaches about 60 °, the tilt angle alpha of inclined plane 41a is not limited thereto, as long as in the scope of 0 °＜α≤90 °, just can.And, compact on fore-and-aft direction in order to make drafting system 3, preferred about 45 °～80 ° of tilt angle alpha.
And inclined plane 41a this moment tilt angle alpha with respect to the horizontal plane is not limited under the situation that has not had balanced controls 43, be configured in the drawing roller unit 30a on the 41a of inclined plane, the angle that 30b slides at the effect lower edge inclined plane 41a of deadweight downwards.For example also can be that 41a tilt angle alpha with respect to the horizontal plane in inclined plane is drawing roller unit 30a, the skid-resistant angle of 30b.
Even in these cases; Also the same with above-mentioned example, make drawing roller unit 30a, 30b along inclined plane 41a move needed power little with balanced controls 43 along the inclined plane 41a suitable part of power that applies of (with drawing roller unit 30a, 30b mobile direction in the opposite direction under the deadweight effect) counter extensioin roller unit 30a, 30b upwards.Thus, the operator can easily carry out the position adjustment of drawing roller unit 30a, 30b.
And; In above-mentioned example; Being used for the balanced controls 43 of counter extensioin roller unit 30a, the 30b application of force is made up of rotatable parts 46 and torsionspring 47; And contact with limiting part 44a through ejection part 46a, drawing roller unit 30a, 30b be not configured under the state on the 41a of inclined plane rotatable parts 46 are remained on ejection part 46a can with contact site 64 position contacting of drawing roller unit 30a, 30b on.But the structure of the limiting mechanism that limit rotation parts 46 move is so long as the structure that can limit rotation parts 46 moves is not limited to be arranged on the limiting part 44a on the attaching parts 44 that connect 2 axle 42b.
And; Limiting part 44a can also be set; In this case; 30a, 30b are not configured under the state on the 41a of inclined plane in the drawing roller unit, ejection part 46a not can with contact site 64 position contacting, but can be just passable with contact site 64 position contacting etc. as long as make before 30a, 30b are about to be configured on the 41a of inclined plane rotatable parts 46 move to ejection part 46a in the drawing roller unit against the application of force of torsionspring 47.
And balanced controls 43 are not limited to the structure of rotatable parts 46 with torsionspring 47 formations.For example, balanced controls 43 compression spring that also can extend in parallel with the incline direction with inclined plane 41a and the ejection part of ejection on contact site 64 that be arranged on the upper end of compression spring constitute.And balanced controls are not limited to use spring and the structure that forms, also can be for example with formation such as cylinders.
And in above-mentioned example, balanced controls 43 are through counter extensioin roller unit 30a, the 30b application of force make drawing roller unit 30a, 30b can not obtain balance downwards slidably at the effect lower edge inclined plane 41a of deadweight from the below.But balanced controls 43 are not limited to the structure of counter extensioin roller unit 30a, the 30b application of force from the below.
In the variation, the balanced controls 80 that are provided with as shown in Figure 8 replace balanced controls 43 (with reference to Fig. 3).One end of the hawser 82 that 2 pulley 81a, the 81b that being suspended on of balanced controls 80 is supported on the frame 40 is last is being connected with drawing roller unit 30a, 30b.And the other end of the hawser 82 of balanced controls 80 is connecting weight and drawing roller unit 30a, the roughly the same counterweight 83 of 30b.And, thus drawing roller unit 30a, 30b be balanced hammer 83 through hawser 82 along upwards (with the effect opposite direction of moving direction down) pulling (application of force) of inclined plane 41a in deadweight.In this case, drawing roller unit 30a, 30b do not pull and can get access to balance downwards slidably at the effect lower edge inclined plane 41a of deadweight through being balanced mechanism 80.
And in the above-mentioned example, these 2 local stretching sliver S between back roller 11 and the 3rd roller 12 and between the 3rd roller 12 and the intermediate calender rolls 13 are necessary that the length according to the fiber of sliver S changes the interval of these drawing roller.Therefore, 2 the drawing roller unit 30a, the 30b that possess rear winding drum 11b and the 3rd bottom roller 12b respectively can be moved along inclined plane 41a, but the drawing process of sliver S is not limited thereto.
For example, only make under the situation of sliver S stretching, as long as it is just passable that a drawing roller unit can be moved along inclined plane 41a in a place.
Perhaps, be that the place more than 3 makes under the situation of sliver S stretching, the bottom roller more than 3 constitutes the drawing roller unit, and it is just passable that this drawing roller unit more than 3 can be moved along inclined plane 41a.
And,, be not limited thereto though the example that the utility model is used for the drafting system 3 that sliver S walks from the top downwards has been described in the above-mentioned example.For example, also can be opposite with above-mentioned example, the utility model is used for the drafting system of sliver S from the walking of lower direction top.
