And, as shown in Figure 5 in the moment that lifting unit 78 has moved certain distance downwards, block to the upper end of the light core pipe 95 of light accepting part 81b from the light-projecting portion 81a of core pipe detecting sensor 81, and detect the upper end of knockout pipe 95.Core pipe detecting sensor 81 sends to unit controls portion 50 with the detection signal that expression detects core pipe 95.When unit controls portion 50 received this detection signal, calculating part 87 calculated the core length of tube according to this detection signal.Then, through update portion 88 the core length of tube that is calculated is stored in the storage part 86.
Afterwards, lifting unit 78 continues to descend, and detects the conical surface portion that supplies spool 21 through conical surface portion detecting sensor 80 specifically.When unit controls portion 50 receives the detection signal of conical surface portion detecting sensor 80; The position that calculating part 87 calculates conical surface portion; And, calculate and supply the coiling amount of thread of being reeled on the spool 21 according to the core length of tube of being stored in the position of resulting conical surface portion and the storage part 86.
In addition, to the amount of thread of the confession spool 21 that supplies spool maintaining part 71 to supply with, be not limited to certain all the time (full amount).For example, under the situation of following that kind, can think and supply with the partly confession spool 21 of volume to winding unit main body 16.Promptly; Though till winding unit main body 16 is supplied with the confession spool 21 of full volume and partwayed, successfully batch operation; But from begin midway because joint error becomes reason such as take place frequently, sometimes maybe yarn by the stage before whole unwindings, supply spool 21 just to be discharged from winding unit main body 16.In this case, operating personal carries out disposal that the reason of joint error is removed etc. to the confession spool 21 of being discharged (the confession spool of half volume), and should supply spool 21 to put into once more in the bobbin magazine rotating disk 63.So partly the confession spool 21 of volume can be fed into winding unit main body 16.But according to the formation of this embodiment, the confession spool for this half volume through measuring the position of core length of tube and conical surface portion practically, also can suitably calculate coiling amount of thread (leftover yarn amount) thus.
After as above-mentioned, calculating the coiling amount of thread, carry out joint through the yarn of 14 pairs of package 30 sides of piecing devices and the yarn of confession spool 21 sides, and begin to reel.Batch in the operation at this, unit controls portion 50 is according to the detection signal from 80 inputs of conical surface portion detecting sensor, the control that the lifting unit 78 of apparatus for unwinding 12 is moved.More specifically, detect through 80 pairs of conical surface portion detecting sensors and the decline of yarn, and drive stepper motor 79 accordingly therewith, and movable part 76 is descended from the conical surface portion that the unwinding that supplies spool 21 is accompanied.The size of the air ring that produces in the time of thus, can suitably being controlled at from confession spool 21 unwinding yarns.
Unit controls portion 50 is according to the coiling amount of thread of the confession spool 21 that is calculated by calculating part 87 and the amount of thread (batching amount of thread) of reeling to package 30 from this confession spool 21; Calculate current leftover yarn amount, and control tension applying device 13 according to resulting leftover yarn amount.Thus, control that the leftover yarn quantitative change tension force increase after a little while that supplies spool 21 is suppressed can be correctly carried out, therefore the quality of package 30 can be improved.
When the unwinding of the yarn of on supplying spool 21, being reeled was all over, the confession spool 21 that becomes bare bobbin was discharged to suitable place from supplying spool maintaining part 71.Then, import new confession spool 21 from bobbin magazine formula feedway 60.So unit controls portion 50 handles with above-mentioned mensuration of likewise carrying out the core length of tube, and obtains the core length of tube of the confession spool 21 of new supply, and begins to batch operation.In the Tension Control of carrying out at this moment, use the value of the core length of tube of newly obtaining.
Then, to judging part 89 begin to batch the time be provided with the error judgment processing describe.In the automatic bobbin winder of this embodiment, preestablish the shortest core length of tube (core length of tube lower limit) that can suitably batch operation in winder unit 10.The above-mentioned error judgment processing that is provided with is according to this shortest core length of tube, to judge that supplying spool 21 whether suitably to be set to is provided with on the position.
Below, be elaborated.In unit controls portion 50, store in advance and make core pipe detecting sensor 81 move to the drive amount with the required stepper motor 79 in the corresponding position of the shortest above-mentioned core length of tube from above-mentioned position of readiness.Then; Even the above-mentioned drive amount of stepper motor 79 drivings (even promptly core pipe detecting sensor 81 arrives and the corresponding detection positions of the shortest core length of tube), this core pipe detecting sensor 81 are not being detected under the situation of core pipe 95 yet, judging part 89 is judged as to have produced error is set.
Thus, under the situation of the confession spool 21 that is provided with the core length of tube shorter, can detect to unusually than the shortest core length of tube.In addition, even supplies spool 21 not to be set under the situation on the tram, also can the judgment processing of slipping up be set and detect through this in the error of throwing a spear owing to the confession spool 21 of bobbin magazine formula feedway 60.
