-steps A): when bobbin-winding machine was extracted the bobbin 2 of preparation on its plate, by opening block 18 and by load-transfer device 11 plate being left, workstation was open to this plate.Owing to there is not a bobbin, therefore electro-optical tubes 14 is not activated, and sends new pending bobbin and must introduce signal in this position.Block 18 is closed once more so that stop to arrive the new bobbin of handling.
-step B): have bobbin in holding fix, electro-optical tubes 13 is activated then; Block 1A is removed, and load-transfer device 11 is brought plate in the control position into its bobbin, replaces the bobbin that pre-processing is intact and be removed.
-step C): holding fix is idle now, and electro-optical tubes 13 is not activated, and administrative unit requires to have the new plate of pending bobbin and close block 1A: load-transfer device 11 brings new bobbin, and next step B is carried out in its exciting light fulgurite 13 and preparation.
-step D): in case pending new bobbin 2 enters control position, and in case locked against block 18, the electro-optical tubes 14 controlled pressure plates 17 of center roller 3A that is activated and dallies, with the motor-driven roller 3 of its backup, it is used for driving the bobbin rotation of processing.
-step e): controller 4a is axle 4 top near bobbins, so that with the vertical position that is centrally located in of bobbin 2.
-step F): throttle gate 8 is opened to the maximum flow of mouth 5.
-step G): roller 3 is activated, and makes bobbin 2 at the specific revolution of rotation in the yarn reserve unreeling direction of bobbin or the setting of its base.Because mouth 5 in-to-in strong pumping, slit 5A has the sizable swabbing action towards the reeled yarn end of handling middle bobbin yarn 16, with its inside from the suction nozzle 5 of bobbin own.The signal of sensor 7 sends the signal that has yarn 16 for awaiting orders, and it is in vibration of mouth 5 in-to-in tops and swing.
-step H): in case detect yarn, throttle gate 8 is closed once more, and the rotation of bobbin 2 is flowed and stopped to maintenance low discharge " closing "; By this operation, yarn 16 still is tightened up, the opening that it can leave slit 5A and enter scissors 15.
-step I): activate scissors 15 and be used to cut off the yarn 16 that is brought to the slit outside, wait for that selectively the yarn in the scissors 15 exists sensor 9 to send the acknowledge signal that has yarn.
-step J): carry out and cut off, yet the inner and stronger air-flow of bottom maintenance towards the pipe of bobbin, so that by means of the suction nozzle with battery unit 10 tractives reeled yarn end that cuts into required size wherein that is arranged on below the bobbin 2, suction nozzle with battery unit 10 attracts yarns to pass hole 20 and/or the Venturi nozzle 12 that is arranged on the axle 4.This Venturi nozzle provides pressurized air, and attracts air from the top of axle 4 towards the pipe inside of handling middle bobbin 2, brings the reeled yarn end that is cut into required size yarn 16 for this reason.According to a preferred embodiment of the present invention, the length of the cut-out reeled yarn end that will insert at the top of pipe, be conditioned by on support 15B, scissors 15 being set with the adjustable height in top with respect to the pipe of handling middle bobbin 2, for the purpose of simplifying, the control apparatus of support 15B does not illustrate in the accompanying drawings.

-step L: center roller 3A is controlled away from plate 17 in idle running, with its release.
-step M: bobbin 2 is prepared to be extracted by bobbin-winding machine.
When the difficult surface from bobbin itself of the yarn on the pending bobbin discharged, no matter whether because yarn " crinosity " and/or because its coiling has sizable tension force, the preferred circulation of carrying out correction and its were more reliable.In a such circulation, with respect to the circulation of earlier examples, inserting step E between aforementioned on-cycle step e and step F
*, this step e
*Use device 6A, it makes reeled yarn seek end hook 6 and presses bobbin 2.Device 6A makes reeled yarn seek end hook 6 towards bobbin 2, and its bus along bobbin itself is slided so that promote or remove the reeled yarn end of fastener 19, also may be that it is drawn back.For this purpose, the roller 3 that is used for rotation processing middle bobbin 2 can drive in cw and the anticlockwise direction at two hand of rotation.
Step e
*Execution as described below.At first carry out hook 6 at a slow speed, descending motion, simultaneously bobbin 2 rotates in its coiling direction, hook finds the coiling yarn on its top, and the main body of its reeled yarn end from bobbin 2 discharged.Perhaps, hook up if the reeled yarn end stops because it is maintained at the bottom of pipe, hook draws loose yarn.Still do not need to activate the maximum aspiration of mouth 5.In the ending stage of this decline, the separation of the administrative unit of pre-processing controller control bobbin 2 and the rising that reeled yarn is sought end hook 6.
Cycle of treatment begins step F-M once more, and difference is, because step e
*, on the bus of bobbin 2, having the loose free yarn of screw type, this yarn is not limited by the base of bobbin or pipe.As described, during step F, the suction of mouth 5 is activated into maximum horizontal, and the yarn of drawing from bobbin enters mouth 5 and there are sensor 7 generation effects in the yarn mouth itself.The scopiform element 50 of seeking end hook 6 or Fig. 4 by the reeled yarn of Fig. 1 picks up the additional step E of bobbin 2 reeled yarn ends
*Can be to have ready conditions or unconditional mode is carried out.
In mode with good conditionsi, it can be programmed and be used for all pending yarn types, carry out above-mentioned basic cycle and finish up to step G, and if when described step G ending sensor 7 send signal and obtained the reeled yarn end by mouth 5, circulation continues normal operation and does not carry out described step e
*On the other hand, if sensor 7 does not send the reeled yarn end only by picked " successful result " signal of suction, bobbin pre-processing administrative unit is given an order and is interrupted carrying out to the basic cycle of step G, make it return step F and order then and begin to restart circulation, and continue to carry out additional step E from step F
*, be used for seeking and separation reeled yarn end by mechanical hook device 6 or brush device 50.
In unconditional mode,, in the administrative unit working cycle is programmed for before step F inserting step E unchangeably preferably when the yarn in the processing more when " difficulty "
*, avoid after step G, interrupting circulation and avoid returning after attempting only seeking end by the reeled yarn of mouth 5 suctions.
A kind of improvement embodiment according to apparatus of the present invention is described with reference to accompanying drawing 2-5 below; This device can be with the stability work of bigger output and Geng Gao.
In the prior art, utilize plate 17 as means of delivery and the support of handling middle bobbin, as in the present invention, the rotation of bobbin is also carried out by being rotated with described plate by roller 3: plate will rotatablely move by friction and pass to bobbin.The pin 21 of plate 17 must be made the internal diameter that diameter is slightly less than the pipe 23 of bobbin 2, so that allow easily respectively bobbin to be inserted on the plate 17 or slave plate 17 taking-ups.The transmission that rotatablely moves the therefore front friction between the upper annular surface of the flange 24 by pipe 23 circumference base edges and plate 17 takes place.
But in order to improve the transmitting torque between these two elements 23,24, improvement is the center improvement of system 4 and controller 4A thereof of the axle of bobbin 2, be used for approaching/away from the top of the pipe 23 of bobbin 2, therefore as shown in fig. 1, center bobbin 2 on plate 17 and press its flange 24 so that transferable torque is brought up to the level of expectation.
As shown in Figure 3, the axle 30 that centers of bobbin is separated by two and coaxial element 31 and 41 is made, be equipped be used for approaching/away from the device at pipe 23 tops of bobbin 2, abut against the top of pipe 23 up to them, described device also allows the mutual motion in axial direction between these two elements 31,41.
First element, 31 forms are the conical butt funnel, have side breach 32 and point to slit 5A so that allow to be entered by the yarn of mouth 5 suctions, also have narrow lateral opening 34, and it is in the side and moves therein facing to the hold-down arm of breach 32, the second elements 41.This element 41 is at cavity and the funnel internal motion of forming first element 31.
In order to obtain the transmission of torque in plate and pipe bracket expectation, the administrative unit at coiler pre-processing station can be preset as the compressed-air supply pressure control that will supply with these pneumatic pistons and change for the work of treatment of finishing with the need.
Therefore axle 30 is formed by two parts 31 and 41, realizes following function:
-pipe 23 tops are centered,
-will manage 23 to press against on the plate 17,
-catch preparation at the yarn of managing between top and the axle 30,
In-the reeled yarn end tubular stinger after will handling.
In Fig. 4, illustrate an embodiment according to apparatus of the present invention, wherein reeled yarn is sought end member spare and is realized that by brush 50 it supports by device 50A, described device 50A supports this brush by the arm 51 that can be parallel to bobbin 2 axial-movements, flexibly reeled yarn is sought end brush 50 and is pressed against on the bobbin 2.In order to pick up the reeled yarn end from bobbin, device 50A extension arm 51 also makes brush 50 against bobbin, and its bus along bobbin itself is slided so that promote the reeled yarn end of fastener 19.Seek end member spare 50 against bobbin between moving period at the scopiform reeled yarn, roller 3 rotates in the bobbin unreeling direction.
Brush 50 resilient mountings by arm 51 allow brushes itself to move along line 52, and are consistent with the profile of bobbin bus, also move along with the truncated cone part of end definitely.Brush 50 can be made by common natural or synthetic bristle, is made by little and thin natural or neoprene cylinder.
The treatment step and the motion of the axle of describing with reference to accompanying drawing 3,4 30 in the above described with reference to accompanying drawing 5A-5I below.
In Fig. 5 A, show that bobbin 2 is in the pre-processing position, its center shaft 30 still raises.In Fig. 5 B, shown the extension of piston 35, infundibulate element 31 descends and presses the top of pipe 23, so that pipe is centered and will manage the flange 24 of back up plate.The second axle element 41 keeps raising.
In Fig. 5 C, shown that piston 45 descends along with axle 41 and withdraws, in the top of the cone-shaped end part tubular stinger 23 of its center shaft 41.Because by piston 45 applied pressures, pipe is pressed against plate, so that the rotation of guaranteeing to act on onboard also is passed to bobbin 2 by the front friction.Promote infundibulate element 31 subsequently, withdrawal piston 35 also only stays axle 41 as centering and thrust component.
In the state shown in Fig. 5 C, carry out aforesaid bobbin pre-treatment step E-H, particularly, the step of bobbin rotation is carried out in the following manner, by possible step e
*Be used for seeking end brush 50 and remove the reeled yarn end, the suction of reeled yarn end is entered in the mouth 5, insert the reeled yarn end of yarn 16 in the scissors 15 and enter in the breach 32 of infundibulate element 31, as shown in the structure of Fig. 3 and 5D by means of the reeled yarn that the reeled yarn of Fig. 1 is sought end hook 6 or Fig. 4.
As shown in Fig. 5 E, axle 41 raises by the driven plunger 45 that makes progress.As shown in Fig. 5 F, the infundibulate element 31 of piston 35 elongation and axle 30 descends, and therefore catches at the lower frustoconical face 36 of funnel 31 and manages the reeled yarn end of the yarn 16 between 23 tops.Fig. 5 G has shown that by the cut-out of scissors to yarn 16, Fig. 5 H has shown the effect of the air of the axial pipe 46 in the axle 42 of blowing over element 41.The reeled yarn end that cuts off is inserted in the cavity of pipe 23: the amount in the yarn tubular stinger is controlled, because the extra yarn of being reeled by bobbin is stoped at the funnel 31 and the junction surface of managing the reeled yarn end between 23 tops.Fig. 5 I has shown the last lifting of funnel element 31, is used to discharge to the ready bobbin 2 of processing of reeling.
When being used for the yarn of extremely difficult unwinding, it need transmit even higher torque, the invention provides further improvement, is used to improve the friction between pipe 23 bottoms of the upper fringe surface of the flange 24 of plate 17 and bobbin 2.This friction improves as shown in Figure 2 by inserting ring liner 60 acquisitions, for example is fixed on the flange 24, and this liner 60 is made by the material that great friction coefficient is provided, for example soft rubber.As an alternative, for improve the top edge of two mating surfaces-flanges 24 and manage 23 bottom-between curable grip, one or two of these two surfaces can be processed make it more coarse, perhaps can add the coarse liner 60 of independent preparation thereon.
Compare with bobbin preprocessing system of the prior art, package bobbin pretreatment procedure of the present invention and device provide sizable advantage.A plurality of these advantages are worth briefly touching upon below.
Technical solution about current use, it has separated the operation between a plurality of workstations, all pre-processing operations all utilize the bobbin in same position to carry out, saved conveying space, and avoided constituting the repetition of the element of these workstations from a workstation to another workstation.Bobbin pre-processing on-cycle is finished by series of steps and is carried out, and wherein each subsequent step is all carried out on the basis of " successful result " signal of receiving previous step.The administrative unit of pretreating device allows to change circulation and can change its operation according to producing needs.The arbitrary steps that does not obtain good net result can repeat the number of times of predetermined number, even changes its parameter, so that obtain the circulation of bobbin pre-processing flexibly.
Bobbin pretreating device according to the present invention allows in addition along with the work bobbin changes the pre-processing operation, for example according to the type and the number of yarn, equally can be along with it is wound on the mode on the bobbin and change in its spinning step in front, fixing or insert replenish step E conditionally
