On the other hand, the twizzle parts 22 of above-mentioned Yarn relaxation removal device 7 are assembled independently with the rotary system of above-mentioned lax removal roller 21, so that it rotates freely alone.Particularly, above-mentioned twizzle parts 22 by be formed with via Bearning mechanism 43 relatively with one heart rotation be supported on flyer spindle axle 44 on the above-mentioned inboard pole piece 29 freely, be fixed in the flyer spindle 45 on the outer end 44a of this flyer spindle axle 44 and extend to the structure that above-mentioned magnetic field forms the endless member 46 that space 42 interior hysteresis materials constitute and constitute.
This flyer spindle 45 be engage (hook spinning yarn SY) with above-mentioned spinning yarn SY, with spinning yarn SY towards the suitably crooked shape of the outer peripheral face 33a of above-mentioned lax removal roller main body 33.
In structure as described above, these Yarn relaxation removal device 7 following such actions.By above-mentioned magnetic field being formed magnet exciting coil 35 energisings of mechanism 34, inboard pole piece 29 and outside pole piece 31 are by excitation.The magnetic field that forms between the outside magnetic pole 39 of the inboard magnetic pole 37 of above-mentioned inboard pole piece 29 and outside pole piece 31 forms in the space 42, and configuration is assembled in integratedly on the twizzle parts 22 so that its B-H loop parts 46 that intersect with magnetic field.Like this, by corresponding to the lax electromagnet of removing roller 21 with corresponding to the B-H loop parts of twizzle parts 22, can produce rotating torques this lax removal between roller 21 and the twizzle parts 22 that rotate freely.
Specific embodiment as shown in Figures 3 and 4 is such, makes magnet exciting coil 35 be stationary system, and inboard pole piece 29 and outside pole piece 31 are configured on this magnet exciting coil 35, and they and the lax roller 21 of removing are rotated integratedly.By such structure, if to magnet exciting coil 35 energisings, then magnetic field rotates with the lax roller 21 of removing.By will with twizzle parts 22 be the B-H loop component configuration of one in this magnetic field, the lax removal roller 21 with respect to rotation can obtain relative rotating torques in twizzle parts 22.
This rotating torques changes according to the size in magnetic field, so by voltage or electric current that magnet exciting coil 35 is applied are changed, can access rotating torques arbitrarily.As a result, by importing predefined controlling value, can be rotating torques arbitrarily by easy operating and setting.
In above-mentioned structure,, can change the torque of a plurality of spindles together by upper control device is set.And then, owing to can also in spinning, change rotating torques, so can also make tension variation midway energetically what batch.In addition, if the mechanism of measuring the yarn tension of reality when spinning is set, then can also carry out FEEDBACK CONTROL, so even make under the situation of tension variation in certain reason because of external interference etc. based on this signal, also can make changes of magnetic field in real time, and revert to tension force arbitrarily.
Below, the running of the spinning machine 1 of said structure is described.Each spinning unit U of spinning machine 1 sends into draw-gear 4 fibre bundle Y in spinning apparatus 5.Then, in spinning apparatus 5 by the spinning yarn SY that spins and generate by yarn feeding device 6 side feeding downstream, by cutter device 16, yarn clearer 17, via Yarn relaxation removal device 7, finally be transported to batching apparatus 8, and be used as coiling package WP and batched.
If the yarn clearer 17 of any spinning unit U detects the defective of spinning yarn SY, then the not shown cell controller of this spinning unit U cuts off spinning yarn SY by cutter device 16, therewith roughly simultaneously, the back roller that makes draw-gear 4 stops 10 rotation with the side roller 9.Fibre bundle Y, will attract remove by not shown attraction mechanism to 10 and continue intermediate calender rolls in the rotation and be cut off in the mode of tearing between to 12 at the side roller that stops than the spinning yarn SY of place of incision by the part in downstream.
The cell controller of spinning unit U sends to joint chassis 3 with the joint request signal, and the position that joint chassis 3 moves in the face of this spinning unit U stops.So, the be in due course rotation of lax removal roller 21 of beginning Yarn relaxation removal device 7 of cell controller.In addition, meanwhile, the upstream side guide 23 of Yarn relaxation removal device 7 is advanced by cylinder 24, keep the silk road so that next Fang Sha spinning yarn SY can not engage with the twizzle parts 22 of Yarn relaxation removal device 7 when not required.
Then,, then roughly synchronously begin the driving of draw-gear 4 and spinning apparatus 5, attract to catch from spinning apparatus 5 spun spinning yarn SY by above-mentioned suction tube 18 with it if the suction tube 18 of joint chassis 3 is rotated upward.In addition, simultaneously in batching apparatus 8 sides, the attraction mouth 19 of joint chassis 3 rotates downwards, and attraction is also caught the yarn ends that is wound on the coiling package WP.Then, suction tube 18 is directed to the yarn ends separately that attracts mouth 19 to be attracted and carries out joint in the piecing devices 20.
Then, before the joint operation in beginning piecing devices 20, cylinder 24 retreats in Yarn relaxation removal device 7, and makes upstream side guide 23 move to going-back position.So the silk road of spinning yarn SY is changed to, make it can be not overlapping with the rotational trajectory of the flyer spindle 45 of twizzle parts 22.As a result, spinning yarn SY is wound up on the outer peripheral face 33a of lax removal roller 21 by flyer spindle 45.
That is, from the continuation that spins of the spinning yarn SY of spinning apparatus 5, so keep such state upstream side at piecing devices 20, spinning yarn SY can be detained in large quantities during the joint operation in piecing devices 20.Yarn relaxation removal device 7 is wound up into lax the removal on the roller 21 with spinning yarn SY during by the joint operation in piecing devices 20, can prevent the lax of spinning yarn SY or is detained, and can realize that level and smooth joint operation and spinning restart operation.
As mentioned above, flyer spindle 45 and flyer spindle axle 44 can rotate independently with the lax roller 21 of removing, but by the above-mentioned mechanism that constitutes by electromagnet and B-H loop parts 46, a certain size above load (than the big load of hysteresis torque that acts on electromagnet and the B-H loop parts) of short of effect, flyer spindle 45 just rotate integratedly with the lax roller 21 of removing.When above-mentioned joint operation, because the downstream of spinning yarn SY stops, the load that is applied on the flyer spindle 45 is less, so flyer spindle 45 rotates with lax roller 21 one of removing, spinning yarn SY is wound up into the lax periphery of removing roller 21.
After the joint end of job of piecing devices 20, in coiler device 8, make coiling package WP rotation, and restart batching of spinning yarn SY by rolling tube.
As mentioned above, from spinning apparatus 5 spun spinning yarn SY from joint operation zero hour of piecing devices 20 to batch restart during, batched on the outer peripheral face 33a of the lax removal roller 21 that continues rotation.But, if restart the operation of batching of batching apparatus 8, then owing to be set with the ratio of output speed with the coiling speed of batching apparatus 8 of yarn feeding device 6, so that spinning yarn SY is applied suitable tension force, so compare with being wound up into the lax yarn speed of removing on the roller 21, the yarn speed of drawing from lax removal roller 21 is bigger.Therefore, the flyer spindle 45 of Yarn relaxation removal device 7 rotates independently with the lax removal roller 21 that continues rotation to take-up direction, batches and is stored in the lax spinning yarn SY that removes on the roller 21 and separated easypro gradually.In addition, the tension force that spinning yarn SY is at this moment applied is determined by twizzle parts 22 of the present invention and the lax relative rotating torques of removing between the roller 21.
