Then, with reference to Fig. 3 to Fig. 6 the formation of apparatus for unwinding 12 and core pipe detecting sensor 81 is described.
As shown in Figures 1 and 2, the apparatus for unwinding 12 of present embodiment possesses fixed parts 75, propulsive effort switching mechanism 85, movable part 76, stepper motor (drive division) 79 and conical surface section detecting sensor 80 as main composition.In addition, as mentioned above, this apparatus for unwinding 12 possesses core pipe detecting sensor 81.
Fixed parts 75 is fixed on the unit framework 11.Be formed with for the contraction flow region of controlling air ring (omitting diagram) in the bottom of this fixed parts 75.From the yarn of pulling out for spool 21, be directed to tension applying device 13 through this contraction flow region.
Propulsive effort switching mechanism 85 is used for the power of the hand of rotation of stepper motor 79 is converted to the power of rectilinear direction, possesses lifting unit 78 and threaded shaft 77.Threaded shaft 77 disposes towards above-below direction (i.e. the direction parallel with the set length direction for spool 21), and is supported as rotating.In addition, during from top view, lifting unit 78 becomes the shape that approximate U word is turned upside down.This lifting unit 78 can keep forming the movable part (contact component) 76 of tubular.
This lifting unit 78 is supported by installing component 74.Have tapped bore at installing component 74, by screw togather threaded shaft 77 in this tapped bore, lifting unit 78 is installed on the threaded shaft 77 thus.Side end at threaded shaft 77 links the motor drive shaft that stepper motor 79 is arranged.In addition, limit above-mentioned lifting unit 78 to the movement of hand of rotation by suitable member, so that it does not rotate integratedly with threaded shaft 77.
In this consists of, when stepper motor 79 drives and during threaded shaft 77 rotation, lifting unit 78 along the axis direction of threaded shaft 77 and upward or the below move.New stepper motor 79 is suitably controlled during for spool 21 or when carrying out the joint operation arranging, and makes movable part 76 (lifting unit 78) for the position of readiness standby above the spool 21.In addition, situation about having finished for the setting of spool 21 or the joint end of job situation under, control step motor 79 is so that movable part 76 descends from above-mentioned position of readiness, and and for the position relationship of realizing between the conical surface section of spool 21 stipulating.In addition, so-called conical surface section, mean among for formed layer on the spool 21, be positioned at yarn 20 unwinding sides inclination the position.
Conical surface section detecting sensor (conical surface section test section) 80 is for detection of the conical surface section for spool 21.The conical surface section detecting sensor 80 of present embodiment constitutes the transmission-type photoelectric sensor with light-projecting portion 80a and light accepting part 80b.The detection signal that conical surface section detecting sensor 80 detects is input to unit controls section 50.
Core pipe detecting sensor 81 (core pipe test section) is for detection of the length of the core pipe 95 that supplies spool 21.Same with above-mentioned conical surface section detecting sensor 80, the core pipe detecting sensor 81 of present embodiment constitutes the transmission-type photoelectric sensor with light-projecting portion 81a and light accepting part 81b.This core pipe detecting sensor 81 is configured in the central authorities of lifting unit 78 when observing in the side, in order to can detect the center of core pipe 95.In addition, core pipe detecting sensor 81 and conical surface section detecting sensor 80 all are configured on the lifting unit 78, and 2 sensors move up and down simultaneously along with the lifting of lifting unit 78.The detection signal that core pipe detecting sensor 81 detects is input to unit controls section 50.
In addition, as shown in Figure 2, unit controls section 50 possesses handling part 84, and this handling part 84 carries out various processing according to the test section signal of core pipe detecting sensor 81.This handling part 84 has calculating part 87, renewal section 88 and judging part 89.In addition, unit controls section 50 possesses storage part 86, the core length of tube that 86 storages of this storage part calculate according to the detection signal of core pipe detecting sensor 81.
Calculating part 87 carries out the processing that the driving amount (amount of movement of the core pipe detecting sensor 81 that has moved by stepper motor 79) according to stepper motor 79 is calculated the core length of tube.More specifically, unit controls section 50 initial control step motors 79 make lifting unit 78 move to position of readiness.Afterwards, unit controls section 50 makes stepper motor 79 rotations and lifting unit 78 is descended with specified speed in the state of supervision core pipe detecting sensor 81.In addition, by suitable counting machine, to counting to the quantity of the drive pulse of stepper motor 79 transmissions this moment.
Then, when lifting unit 78 from above-mentioned position of readiness descended the moment of certain distance, when core pipe detecting sensor 81 detects the core pipe, above-mentioned calculating part 87 calculates the dropping distance (miles of relative movement) of core pipe detecting sensor 81 according to the count value (being the anglec of rotation of threaded shaft 77) of the drive pulse of stepper motor 79 and the pitch of threaded shaft 77.Then, calculating part 87 deducts resulting dropping distance from predetermined distance, obtains thus the core length of tube for spool 21.
In addition, unit controls section 50 goes back control step motor 79 after core pipe detecting sensor 81 detects the core pipe, so that lifting unit 78 continues to descend.Then, when lifting unit 78 from above-mentioned position of readiness descended the moment of certain distance, when conical surface section detecting sensor 80 detects conical surface section, calculating part 87 is obtained the position of conical surface section by the method almost identical with the situation of above-mentioned core pipe detecting sensor 81.
When obtaining as described above the position of core length of tube and conical surface section, the winding yarn amount (leftover yarn amount) for spool 21 when 87 pairs of calculating parts begin to batch is calculated.By according to position, the use suitable function of conical surface section with respect to the core length of tube, can obtain this leftover yarn amount.
In addition, when obtaining the core length of tube by calculating part 87, the core length of tube that renewal section 88 usefulness calculate covers the processing of the core length of tube of storing in (renewal) storage part 86.Thus, when supplying with for spool 21 to winding unit main body 16, the core length of tube of this confession spool 21 is stored in the storage part 86 again.
Judging part 89 judges for spool 21 whether process from the judgement of setting position disengaging.The detailed content that the judgement of this judging part 89 is processed is with aftermentioned.
The processing of the unit controls section 50 when then, being set in the confession spool maintaining part 71 to confession spool 21 describes.As shown in Figure 4, in the moment being supplied with from bobbin magazine formula feedway 60 for spool 21 after tight being set to for spool maintaining part 71, movable part 76 is kept out of the way the position of readiness for spool 21 tops.And when finishing to the setting that supplies spool maintaining part 71 for spool 21, stepper motor 79 drives, and lifting unit 78 is mobile downwards thus.
And, in the moment that lifting unit 78 has moved certain distance downwards, as shown in Figure 5, 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 section 50 with the detection signal that expression detects core pipe 95.When unit controls section 50 received this detection signal, calculating part 87 calculated the core length of tube according to this detection signal.Then, by renewal section 88 the core length of tube that calculates is stored in the storage part 86.
Afterwards, lifting unit 78 continues to descend, and detects the conical surface section that supplies spool 21 by conical surface section detecting sensor 80 specifically.When unit controls section 50 receives the detection signal of conical surface section detecting sensor 80, the position that calculating part 87 calculates conical surface section, and the core length of tube according to storing in the position of resulting conical surface section and the storage part 86 calculates for the winding yarn amount of reeling on the spool 21.
In addition, to the amount of thread for spool 21 of supplying with for spool maintaining part 71, be not limited to all the time certain (full amount).For example, in following such situation, can think and supply with the half confession spool 21 of rolling up to winding unit main body 16.Namely, although successfully batch operation to what 16 supplies of winding unit main body were completely rolled up for spool 21 and till partwaying, but from begin midway because joint error becomes the reason such as take place frequently, sometimes may be at yarn by the stage before whole unwindings, be just discharged from winding unit main body 16 for spool 21.In this case, operating personal carries out the reason of joint error is removed the disposal that waits for spool 21 (half volume for spool) to what discharge, and should supply spool 21 again put in the bobbin magazine rotating disk 63.So, should can be fed into winding unit main body 16 by half spool 21 that supplies of rolling up.But according to the formation of present embodiment, the spool that supplies for this half volume by measuring practically the position of core length of tube and conical surface section, also can suitably calculate winding yarn amount (leftover yarn amount) thus.
After calculating as described above the winding yarn amount, carry out joint by 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 section 50 is according to the detection signal from 80 inputs of conical surface section detecting sensor, the control that the lifting unit 78 of apparatus for unwinding 12 is moved.More specifically, detect by the decline from the conical surface section that accompanies for the unwinding of spool 21 of 80 pairs of conical surface section detecting sensors and yarn, and drive accordingly stepper motor 79 therewith, and movable part 76 is descended.The size of the air ring that produces in the time of thus, can suitably being controlled at from confession spool 21 unwinding yarn.
When the unwinding for the yarn of reeling on the spool 21 all finished, what become bare bobbin supplied spool 21 from being discharged to suitable place for spool maintaining part 71.Then, import new confession spool 21 from bobbin magazine formula feedway 60.So unit controls section 50 processes with above-mentioned mensuration of similarly carrying out the core length of tube, and obtains the core length of tube for spool 21 of new supply, and begins to batch operation.In the tension force 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 the error that arranges judge to process and to describe.In the automatic bobbin winder of present embodiment, preset the shortest core length of tube (core length of tube lower limit) that can suitably batch operation in winder unit 10.Above-mentionedly error is set judges and to be treated to according to this shortest core length of tube, judge for spool 21 whether suitably be set on the setting position.
Below, be elaborated.In unit controls section 50 pre-stored have make core pipe detecting sensor 81 move to the driving amount of the required stepper motor 79 in the position corresponding with the shortest above-mentioned core length of tube from above-mentioned position of readiness.Then, even the above-mentioned driving amount of stepper motor 79 drivings (even namely core pipe detecting sensor 81 arrives detection position corresponding with the shortest core length of tube), this core pipe detecting sensor 81 are not being detected in the situation of core pipe 95 yet, judging part 89 is judged as to have produced error is set.
Thus, be provided with the core length of tube shorter than the shortest core length of tube in the situation of spool 21, can detect as unusually.In addition, even supply spool 21 not to be set in the situation on the tram in the error of throwing a spear for spool 21 owing to bobbin magazine formula feedway 60, also can error be set by this and judge that processing detects.
When being judged as by judging part 89 to have produced when error is set, unit controls section 50 shows these situations in the display frame 91 that body control setup 90 possesses, and the operation of batching of reeling end 17 is stopped.
