Yarn winding machine and method for controlling position of it's robbin

The present invention relates to the control method of a kind of Yarn winding apparatus and position of it's robbin thereof.

As shown in Figure 7 and Figure 8, former Yarn winding apparatus has slotting two parallel seat of reel 2,3 of a plurality of bobbins (paper tube) 1, makes their high speed rotaries respectively with Spindle Motor 4,5.Seat of reel 2,3 is the center by supporting member 6 and bearing cartridge 7 with the axle 9 that is fixed on the up-coiler body 8, can turn round be supported movably.The motor 13 that turns round mobile usefulness is being connected with bearing cartridge 7 with chain 12 by sprocket wheel 10,11.

And, upper bobbin 1a, from the spun yarns Y of spinning machine (the figure do not have expression), through laterally being reeled behind the double action range device 14, when full packages, drive the driving of the motor 13 of usefulness by revolution, upper-lower position is exchanged, the bobbin 1a that forwards the next full packages yarn to doffs, and after forwarding upper bobbin 1b simultaneously to and hanging up yarn, proceeds to reel.And the revolution of reeling control is to go up the revolution of rotating contact roller 15 by detecting with the contact pressure of regulation at bobbin (thread layers 16), is undertaken by joystick (not having expression among the figure) controlled reset Spindle Motor 4,5.

But, because being the bare bobbin 1b with standby, the bobbin 1a of full packages yarn keep the phase places revolution of 180 degree to move, in this moving process, especially shown in the long and two-short dash line among Fig. 7, turned over for 1/4 when circle, the side face of thread layers 16 forms the state that exceeds more greatly in the horizontal.Therefore, exist the installing space of Yarn winding apparatus must be than the big problem of desired width (developed width of up-coiler) in reeling.

The present invention makes in order to address the above problem, and its objective is provides a kind of when bobbin replaces, and thread layers does not exceed the control method of the Yarn winding apparatus and the position of it's robbin thereof of up-coiler transverse width.

In order to achieve the above object, the invention provides a kind of Yarn winding apparatus, be provided with the seat of reel maintaining body, this bobbin maintaining body is when the exchange bobbin is with the spun yarn of coiling when full packages, a plurality of bobbins are suitably moved on the regulation path respectively independently, can maintain their seat of reel simultaneously.Above-mentioned regulation path is the central circular track with any preferably.The seat of reel maintaining body has and the corresponding independent driving mechanisms of each bobbin, perhaps makes the driver train that they move accordingly with each bobbin.

The control method of the position of it's robbin of the Yarn winding apparatus that said structure arranged of the present invention is to make the side face of the thread layers of the winding side bobbin that diameter increases be no more than the datum line that extends along the vertical direction, allow this seat of reel along the regulation path move, and make another side treat the bobbin of pusher side be positioned at the discontiguous position of winding side bobbin on.The path of afore mentioned rules is to be the central circular track with a bit, and datum line is the outer peripheral lines, the line that extends along the vertical direction of the full packages yarn of the lowest positions by circuit orbit preferably.The beginning winding position of winding side bobbin is to spend with interior position 90 with respect to the coiling end position.

With above-mentioned structure, each bobbin can freely change moving of mutual phase place, the bobbin when carrying out full packages alternately and spun reel for yarn around.The path that moves is circular track, is the center with a bit, reciprocally moves.

With above-mentioned method, the bobbin of winding side moves from the position that begins to reel to the inside then according to the increase of bobbin coil diameter, arrives the position of doffing after becoming full packages.The bobbin for the treatment of pusher side then with its concurrently, with batch side neck cotton sewing thread on cop layer and move to the position that begins to reel from the position of doffing non-contiguously.

With the present invention of said structure, can obtain following good effect.

transom

33,34, separate appropriate intervals ground and form bolt hole 49, it is to be used for the in addition bolt tightening of flange of a seat of reel 21,22.Also form the bolt hole 50 that a plurality of bolt ups are used to the up-coiler body 35 at the outer peripheral edges place of bracing frame 36.

Below, the embodiment of the position of it's robbin control method of spinning up-coiler of the present invention is described, and its effect as said structure.

As shown in Figure 1, it is at the center of up-coiler body 35 Widths that the bobbin 24a of full packages is in the position (P1) of doffing, and be decided to be turn round mobile path circular orbit 51 bottom.And the position (P2) of the yarns Y that formally begins to reel is decided to be from the position of doffing (P1), and inhour turns over the positions of about 55 degree.This position that begins to reel (P2) is equivalent to and the rotating contiguously lower position that contacts sieve position 27 of bobbin 24.On the other hand, the bobbin 25 for the treatment of pusher side is only just beginning to be in readiness for action from the positions (P3) that the position of doffing (P1) cw turns over about 95 degree.Therefore, beginning to calculate from the bobbin 24 of winding side, then is that cw changes about 150 degree.

When reeling, make seat of reel 21 revolutions that are in winding side by the revolution of Spindle Motor 26, its bobbin 24 through reciprocating traverse devices 29 with contact the yarns Y that spins that roller 27 hangs down and wind up.By the revolution that is arranged on joystick (not having expression among the figure) the control Spindle Motor 26 on another body.The revolution signal of contact roller 27 is input to joystick, it is controlled to a/s circumferential velocity and bobbin cross angle according to the program of setting.Along with coil diameter increases, the seat of reel 21 that makes winding side bobbin 24 cw revolution gradually moves, and the outer circumference end of layer 16 is maintained in and is positioned at than up-coiler body 35 sides also on the inboard.In other words, in up-coiler body 35, make winding side bobbin 24 not exceed up and down the datum line L that extends, seat of reel is moved to doff position (P1).The seat of reel 21 of winding side is moved continuously, it is moved by stages.In addition,, lifting box 28 is risen, make the bobbin 22 for the treatment of pusher side move to final position of readiness (P4) by stages or quickly from beginning position of readiness (P3) along with coil diameter increases.This final position of readiness (P4) be with the position of doffing (P1) on the discontiguous position of layer 16a of full packages yarn, and be with rise in the discontiguous position of lifting box (28).At present embodiment is to be decided to be from beginning position of readiness (P3) cw to change about 40 degree, and standby is carried out in the position that turns over 135 degree from the position of doffing (P1) clws.

As shown in Figure 4, when the bobbin 24 of winding side when becoming full packages (a), makes its Spindle Motor 26 stop revolution at the position of doffing (P1), make simultaneously to be raised to upper limit position (b) on the lifting box 28.And make bobbin 25 75 degree that move of clockwise direction revolution individually for the treatment of pusher side, make it arrive the position of contact roller 27, hang yarn, simultaneously with the chassis that doffs (not having expression among the figure) etc. to the bobbin 24 of below doff (c).When the end of doffing, make lifting box 28 drop to the lower position quickly, make bobbin 25 revolutions of the bobbin that newly becomes winding side move about 95 degree simultaneously, formally begin reel (d) at beginning winding position (P2).Meanwhile, perhaps before and after this, make bobbin 24 revolutions that become bare bobbin move to beginning position of readiness (P3).

Like this, make two

bobbins

24,25 on circular orbit 51, distinguish the bobbin maintaining body 23 of mobile usefulness by oneself owing to set, make winding side bobbin 24 from beginning winding position (P2) gradually towards following and side shifting inwardly, standby side neck pipe 25 is turned round non-contiguously with winding side bobbin 24 and lifting box 28 to be moved, thereby begin winding position to the process of doffing from yarn, layer 16 can be not outstanding from the Width of up-coiler body 35, and installing space is dwindled.That is, can reduce the space that is provided with in the spinning unit.And the also desirable one-tenth of width of the up-coiler body 35 of formation actual installation spacing is than the bigger a little degree of diameter of the layer 16a of full spool.

Because in the present embodiment, the path that seat of

reel

21,22 is moved makes common circular orbit, thereby can also make the structure of bobbin maintaining body 23 quite simple again.

Because beginning winding position (P2) is fixed on from the position of doffing (P1) greatly about the below slightly of 90 degree relative positions a bit (promptly at 90 degree with interior position), can remain on contact roller 27 and layer 16 contacted points near the upper end of bobbin, thereby can maintain contact pressure in about certain scope.Promptly, also can consider to begin to reel from the upper limit position (position shown in Fig. 4 (c)) of contact roller 27, it is little by little descended, but like this, be envisioned that, except mobile path is become than the complexity, also there is bigger variation the position with respect to bobbin 24 of contact roller 27, and it is inhomogeneous to be easy to generate contact pressure.In addition, because in the present embodiment, only make lifting box 28 in winding process, just merely rise can, therefore make its lifting control also become simpler from the lower position.

In the above-described embodiments, the gyroscopic drive system of seat of reel maintaining body 23 has been omitted, but the motor that can make it on each

disk

31,32 or

transom

33,34, bearing portions is set and turn round mobile usefulness.For example shown in Figure 5, can constitute on the axle 61 in revolution axle center in reality, by bearing 64,65 two-fold

pipe

62,63 is set, respectively the front end of interior pipe 62 is fixed on the disk 31 of front side, fixing the disk 32 of the front end of outer tube 63 and rear side.And install

sprocket wheel

66,67 at the other end of inner and

outer pipes

62,63, they are connected by the sprocket wheels 72,73 of

chain

68,69 with the motor 70,71 of two mobile usefulness of revolution respectively.With this structure just can be by each being turned round mobile usefulness the drive controlling of motor 70,71, each seat of

reel

21,22 revolutions are moved.The control that this revolution is moved for example can be adopted the revolution according to contact roller 27, and instrumentation is extrapolated bobbin diameter, then according to the program that the relation of coil diameter and position of it's robbin is set, determines rotating time and revolution amount of movement.

Can also with the motor of pipe shown in Figure 5 and the mobile usefulness of revolution, disk on one side 31 revolutions be moved as illustrated in fig. 6, between the transom 34 of disk 31 on one side and another side, the rotary motion mechanism of driving device 81 as another side is set.That is,, in the about 45 degree scopes in both sides separately, move, thereby by making driving device 81 suitably flexible, just the position of it's robbin that can obtain stipulating because two seat of

reel

21,22 are the center with the phase bit positions that form 180 degree.Since use this structure, just much of that with the motor of the mobile usefulness of revolution, therefore can make integral structure simple.

In addition, also can be traversing triangle as the reciprocating traverse device, the paddle formula reciprocating traverse device that also can adopt the bar that makes rotation and yarn to traverse with engaging.In addition, in the above-described embodiment seat of reel is made two, also can make the structure more than two.The foregoing description represents that the present invention is applicable to the spinning machine of spindle driving type, and certainly, the present invention also can be applicable to the spinning machine of friction driving type.
