Bont disposes like this: to pass through dynamical axis 17 lifting/decline ring rails 18 and lappet positioning pins 19.Guide wire 19a is set on lappet positioning pin 19, passes guide wire 19a from the yarns Y of front roller 11 conveyings and be directed into bead coil 20, bead coil 20 moves with the rings 18a moving contact ground of ring rail 18.
Dynamical axis 17 is along the longitudinal direction setting of spinning machine, and a plurality of helical wheels 21 (helical wheel only is shown in accompanying drawing 2) are installed on the dynamical axis 17 with preset space length like this, and making can be with dynamical axis 17 rotation.Ring rail 18 supports through a plurality of ramuscule posts 22 (a little pillar only is shown in accompanying drawing 2).The frame (not shown) of each ramuscule post 22 through machine is supported for that make can vertical shifting, forms thread part 22a in the bottom of ramuscule post 22.Thread part 22a is screwed in the nut piece 23, and nut piece 23 rotatably is supported on the desired height position of frame.Nut piece 23 forms the helical wheel (not shown) on outline, this helical wheel and corresponding helical wheel 21 engagements.Similarly risings/following descending mechanism also be that lappet positioning pin 19 disposes, and makes lappet positioning pin 19 and ring rail 18 lifting/decline synchronously.
Dynamical axis 17 is connected through the gear cluster (not shown) with the axle drive shaft of the servomotor 24 that is used as motor.The driving of servomotor 24 is through servo-driver 26 controlled device 25 controls, and controller 25 is as control setup.Servomotor 24 is provided with a rotary encoder 27.Dynamical axis 17 is driven by servomotor 24, makes its rotative speed and hand of rotation freely to change.Dynamical axis 17, ramuscule post 22, nut piece 23, servomotor 24 and gear cluster have formed bont.The structure of above-mentioned bont and Japanese Unexamined Patent Publication No 7-300728 are basic identical.
Controller 25 comprises central processing unit (CPU) 29, program store (ROM) 30, working storage (RAM) 31, input equipment 32, input interface 33, output interface 34, main motor-drive circuit 35 and driven by servomotor circuit 36.CPU29 is connected with phase inverter 16 with main motor-drive circuit 35 through output interface 34.CPU29 is connected to servomotor 24 through output interface 34, driven by servomotor circuit 36 and servo-driver 26.
Counting machine 37 of controller 25 configurations.Counting machine 37 is connected with CPU29 electricity with rotary encoder 27.Counting machine 37 adopts up-down counter; Wherein when the output pulse from rotary encoder 27 is when servomotor 24 normally rotates, to import; Count value increases, and when the output pulse from rotary encoder 27 was to import during in servomotor 24 contrarotations, count value reduced.
CPU29 is based on the predefined routine data operation that is stored in the program store 30.Program store 30 is formed by read-only memory (ROM) (ROM), its storage said procedure data and the required various types of data of this routine data of execution.In the present embodiment, the program stored data are used for increasing in operating winding initial stage and latter stage winding quality.The number, spinning conditions that various types of data comprise spun yarn be spindle rotating speed in the spinning operation and type likelihood data for example, and related data, the for example number of times of the chase of ring rail 18 (chase) for full packages.
According to spinning conditions, program store 30 storage starts to the reference mode of the main motor M velocity variations that forms of stopping to doff from machine, and starts to the for example reverse position correspondence or the relational expression of the ring rail 18 that forms of stopping to doff from machine.In addition, the program store 30 storage cop inclined-plane hypotenuse length standard that carries out normal winding operation (winding quality does not increase) with cause calculates relational expression or the correspondence of the cop inclined-plane hypotenuse length L c that increases winding quality.Term " cop inclined-plane hypotenuse length " refers to the aviation value of the single rising/descending stroke of ring rail of the present invention.

CPU29 is connected with rotary encoder 27 with sensor S1 through input interface 33.CPU29 calculates spinning quality according to the output signal of sensor S1.The sense of motion of CPU29 identification ring rail 18 is promptly discerned the motion up or down of ring rail 18 according to the output signal of rotary encoder 27.In addition, CPU29 calculates the position of ring rail 18 according to the count value of counting machine 37.
Explanation now is according to the operation of the device of the description configuration of preceding text.At first, the number of spun yarn and spinning conditions data for example spindle rotating speed, spinning length, promote class likelihood data in length, benchmark cop inclined-plane hypotenuse length and the spinning operation through input equipment 32 inputs.Bont, drawing-off partial sum spindle drive system system are synchronously driven independently.
CPU29 is according to controlling servomotor 24 and main motor M driven in synchronism through spinning conditions input equipment 32 inputs and that be stored in the working storage 31.When servomotor 24 was driven, dynamical axis 17 was through the gear cluster rotation, thus through helical wheel 21 swivel nut spares 23.The ramuscule post 22 that is screwed into nut piece 23 drives ring rail 18 and moves up or down.Ring rail 18 is upward movement when the normal rotation of servomotor 24, when servomotor 24 contrarotations, moves downward.Pass guide wire 19a and bead coil 20 from the yarns Y of front roller 11, reel to form cop 40 around bobbin B.
CPU29 lifting/decline ring rail 18, the remaining unchanged to top offset Dd of top reverse position PU that makes lifting and the transmission of decline process through ring rail 18 shown in accompanying drawing 1, arrives the upper limit position UL at operating winding initial stages up to ring rail 18.The upper limit position UL of ring rail 18 is confirmed by width in keeping bobbin B by the yarn gripper (spool stand) of the doffer (not shown) in the doffing operation.
Under the normal winding operational circumstances that winding quality does not increase; The driving of CPU29 control servomotor 24; Make when ring rail 18 move with the upward stroke of each cop inclined-plane hypotenuse length or descending stroke cooresponding apart from the time change the hand of rotation of servomotor 24, the bottom reverse position PL of ring rail 18 identical when cop inclined-plane hypotenuse length L c keeps constant like this to top offset Du maintenance.Therefore, under the normal winding operational circumstances, ring rail 18 rising/decline like this: make that the bottom reverse position PL's that shifts ring rail 18 is from the decline process to lifting process also keeps constant to top offset Du.
Simultaneously; When the bottom 40a of the cop 40 that increases at the operating winding initial stage at winding quality forms; Ring rail 18 is raised like this/descends: make the upward stroke and the descending stroke that begin ring rail 18 from operating winding increase gradually, up to reaching predetermined chase number of times.Because the remaining unchanged to top offset Dd of top reverse position PU, ring rail 18 is raised like this/descends, and makes the changing to top offset Du of bottom reverse position PL.In the present embodiment, ring rail 18 is raised like this/descends: make that the profile of bottom 40a is a curved surface, perhaps bottom reverse position PL's increases to top offset Du gradually.
When the top 40b (representing with long and two-short dash line) of the cop 40 that increases at operating winding winding quality in latter stage forms; Ring rail 18 is raised like this/descends: after making that operating winding passes through normal winding operation arrival upper limit position UL; Cop inclined-plane hypotenuse length L c reduces gradually, and the top reverse position PU of ring rail 18 reduces from upper limit position UL.The formation top 40b of the bottom reverse position PL of ring rail 18, promptly in the bobbin B upper area increase of winding quality to top offset Du, be set to the normal winding operational circumstances under identical to top offset Du.Therefore, cop 40 forms like this: the partial continuous of carrying out normal winding operation with same diameter of top 40b and cop 40.Shown in accompanying drawing 3A; By the surface of the top 40b that forms continuously with the bottom part of top 40b (top 40b have larger-diameter bottom part) and the angle θ 1 that forms with the vertical plane of axle of cop 40, with by the top (representing) of the cop that forms under operating in normal winding with solid line with equate with angle α that a vertical plane of cop 40 forms.
After top 40b is completed into, carry out the top and reel so that reel around bobbin B in the position yarns Y that is higher than upper limit position UL, form top 41 at the top of cop 40 like this.The revolution of reeling in the top is equal to or less than 3 times.Through carrying out above-mentioned operating winding, the rising of rings 18a/step-down operation scope is shown in accompanying drawing 1.More specifically; The top reverse position PU of rings 18a is moved to making and is arranged in the straight line; It is positive that the gradient of this straight line begins up to the moment of normal winding EO Te (full packages stops) from operating winding, is moved the position then and is arranged on slope in negative (downwards) straight line.On the other hand; Bottom reverse position PL is moved to being arranged on and stretches out downwards in the curve that forms bottom 40a; Be formed in the straight line of the centre portion (or carrying out the normal winding operation) between part 40a and the 40b, in the production that is used for the straight line above the centre portion that forms top 40b.
Shown in accompanying drawing 3B, form cop 40 by above-mentioned cop build method, this manufacturing process comprises the bottom 40a that is positioned on cop 40 downsides and is positioned at the top 40b on the upside.Therefore, the winding quality of cop is increased for the 40b of top.Although the thickness and the similar factor of length of bobbin, cop diameter (diameter of ring), spun yarn are depended in the increase of incidental looping quality, can estimate approximately to have increased by 5 to 15%.
According to present embodiment, can obtain following advantageous effects.
(1) when carrying out the moulding of cop by the yarn winding shaping; Yarn through the normal winding operation is winding to upper limit position UL; This wherein ring rail 18 bottom reverse position PL keep identical to top offset Du, cop inclined-plane hypotenuse length L c keeps constant simultaneously, the yarn winding quality is increased by means of ring rail 18 rising/declines then; Make cop inclined-plane hypotenuse length L c reduce gradually, and the top reverse position PU of ring rail 18 reduce from upper limit position UL.Therefore, even the length of bobbin B is constant and what carry out is the operating winding of same pipe yarn diameter, it is also many than conventional cop that the winding quality of cop 40 increases.So bobbin change cps yarn production reduces, need not to increase the species number (bobbins that length is different) of bobbin B, this has shortened the time that spinning machine stops to spin.In addition, when yarn was recoiled on bobbin-winding machine, the tube changng frequency of Yarn connecting frequency and unit yarn production reduced, and had improved the capacity rating of bobbin-winding machine thus.
(2) form being set at and ring rail 18 identical under the normal winding operational circumstances of bottom reverse position PL of the ring rail 18 of top 40b to top offset Du.Therefore; Operating winding carries out like this: make lower part and the cop 40 of top 40b continuous with the diameter of same diameter normal winding operation winding part down, the situation winding quality increase that therefore diameter of the lower part of 40b reduces gradually than top.
(3) ring rail 18 is raised like this/descends: the top reverse position PU of the ring rail 18 of the feasible top 40b of formation keeps constant to bottom offset Dd.Therefore, the visual profile in cross section of cutting the top 40b of top 40b along the plane of the axle that comprises bobbin B is a rectilinear form, this than visual profile be curve shape situation more difficulty cause and take off yarn (sloughing).Term " takes off yarn " and refers to the phenomenon that yarn comes off from cop with horn when cop is recoiled in winding process.
(4) behind the formation top 40b, thereby reel in the position yarns Y that is higher than the upper limit position UL under the normal winding operational circumstances around bobbin B in the top.Therefore top 41 is used for preventing the anti-avulsion yarn, thereby than not carrying out the situation of reeling in the top, the quality of top 40b increases.
(5) since bont form like this: make motor special 24 along normal or inverse direction rotary power axle 17 with lifting/reduction ring rail 18; Be easy to change the reverse position of ring rail 18, to change the cop inclined-plane hypotenuse length L c that forms top 40b the latter stage at operating winding.
The invention is not restricted to the foregoing description, can also implement by following example.
When forming top 40b, only need lifting/reduction ring rail 18 like this: make cop inclined-plane hypotenuse length L c reduce gradually, and the top reverse position PU of ring rail 18 reduces from upper limit position UL.Allow lifting/reduction ring rail 18 like this: make no longer the keeping constant to bottom offset Dd but increase continuously of top reverse position PU of ring rail 18.In the case, the surface on the top of top 40b forms curved surface, and this curved surface radially outward expands, so the winding quality of top 40b increases.Also can allow such lifting/reduction ring rail 18: make ring rail 18 top reverse position PU be not to increase continuously but step wise increases to bottom offset Dd.
When forming top 40b, allow to promote like this/reduces ring rail 18: make ring rail 18 bottom reverse position PL to top offset Du, different with under the normal winding operational circumstances, but increase gradually to top offset Du.When promoting/be lowered into, ring rail 18 makes that the diameter of cop 40 reduces gradually when top offset Du increases gradually.Therefore, preferably be set to top offset Du identical with the normal winding operational circumstances, to increase winding quality.
Need not carry out the top reels.
The bont of lifting/decline ring rail 18 can form like this: make the rotating tee of front roller 11 cross gear cluster and be delivered to dynamical axis 17; As Japanese Unexamined Patent Publication No 2-277827 is disclosed, rather than by the servomotor that is used for bont 24 driving dynamical axiss 17.In the case, the switching of dynamical axis 17 between normal rotation and contrarotation carried out through the magnetic clutch that is arranged in the gear cluster.
The drive system of spindle 14 is not limited to belt-driving, and can be by usually said single ingot drive system, in this system each spindle is provided with a motor.Spindle 14 can drive with tangential belt, rather than uses rolling disk 15.
Therefore, this example and present embodiment should be counted as schematic and nonrestrictive, and the details that the invention is not restricted to here provide, but can in the scope of appending claims, modify.
