Below, with reference to accompanying drawing embodiments of the invention are described.
Fig. 1 and Fig. 2 are that expression is used in situation on the automatic bobbin winder suitably to the package quality control monitor unit of the 1st embodiment of the present invention.Automatic bobbin winder is that as shown in Figure 7 more than 1 in package device is set up in parallel.Quality inspection device is provided with the monitor control mechanism of the package p on every batch up gear 1 being monitored usefulness in batching forming process, this monitoring equipment is provided with yarn detecting sensor 22, and this sensor is whether the outside of the outermost layer 21 of the conical specification package of perception p has yarn.Package p is around the goods that batch on the spool B reel for yarn.What is called is batched forming process and is meant that a yarn y batches batching on the spool B (package p), making it grow into the process of full volume package p, carries out the stage that yarn y batches when also comprising joint.The outermost layer 21 of the package p of specification is meant that the axis c with package p is the center, is the outermost layer of the determined layer of circle of radius with this center to package p and the distance that drives the point of contact 25 of drum 8.Under the engagement of conical package p, because the axis c of package p is with respect to axially just different certainly along package p of package p and the radius of outermost layer 21 of tangent line, the package of bevelled, thereby specification vertically p that drives drum 8.Yarn detecting sensor 22 constitutes by the light-projecting component 23 of the laser beam that penetrate to detect usefulness etc. with its photo detector 24 vis-a-vis, be arranged near the point of contact 25 (tangent line) of detection light L by package p and driving drum (journey of traversing drum) 8 that light-projecting component 23 penetrates, driving drum 8 is to make package p rotating with wipe contact.In more detail, be yarn detecting sensor 22 be arranged to detect light L by specification package p outermost layer 21 and drive near the drum 8, and with the discontiguous position of side face of outermost layer 21 and driving drum 8.Even yarn detecting sensor 22 is arranged to detect light L by being to consider that the coil diameter of sending out package p increases near the point of contact 25, do not change with the position of outermost layer 21 corresponding detection light L yet.In the quality inspection device of present embodiment, yarn detecting sensor 22 is arranged to detect light L is directed to package p by yarn y a side (front face side of batch up gear).Like this, unusual (fragmentary yarn, hard waste, the float etc.) of package p can be easily detected, dual detection of looking for broken end or end face to come off can also be carried out.Though package p is bearing on the apron hack lever (package supporting device) 7, along with coil diameter increases, 25 positions, point of contact are stepped back a little, though preferably yes with apron hack lever 7 package p be supported to the coil diameter change, 25 positions, point of contact are also constant.The original purpose of monitor control mechanism is the surface (outermost layer) 21 of monitoring package p, on this meaning, make that to detect near the outermost layer 21 of light L by package p be important.Like this, detection light L and point of contact 25 (tangent line) that light-projecting component 23 penetrates act on abreast, when by the foreign matters such as yarn on the outside of outermost layer 21 detection light L being blocked, just form perception state (ON).Usually, while yarn y be guided the journey groove that traverses that drives drum 89 li Di to move back and forth, be wound onto on the package surface p.Therefore, light L is neighbouring by the side face that drives drum 8, yarn y can be by 22 perception of yarn detecting sensor yet even detect.
Light-projecting component 23 be installed in by support 26 batch up gear 1 this body frame 35 above, photo detector 24 is installed in by support 28 and drives on the set cover 27 of drum 8 front face side F.Cover 27 is made of the plate that section is circular arc, and this plate is provided with near the side face that drives drum 8, is used for preventing that end face from coming off.Being folded back along the peripheral part of the axial end that drives drum 8 than the end in distally from this body frame 35 of cover 27, support 28 is installed on this reflex part 29.And, at the rear side R of batch up gear 1 the centre of gyration point is arranged owing to supporting the apron hack lever 30 of package p, even it is big that coil diameter becomes, the position at point of contact 25 is constant substantially, near the position on the package surface the point of contact 25 can be not moving greatly, even thereby the position of yarn detecting sensor 22 is fixed, it also can often detect with identical condition and have or not foreign matter.That is, the child mechanism of Yarn senser 22 is just passable with the such structure of graphic open-and-shut support 26,28.But, when the surface of yarn detecting sensor 22 and package p excessively near the time because the problem of the young pilose antler of perception outermost layer 21 is arranged, thereby make the slight distance of leaving the surface regulation at least.
And, yarn detecting sensor 22 is associated with bead scrubber 5 (referring to Fig. 1), if perceive foreign matter, by the cutter that is attached to the cutter on the bead scrubber 5 or be provided with yarn y is cut off with method for distinguishing at once, and shown in the equal sign a among Fig. 2, apron hack lever 30 is erected, thereby package p is left drive drum 8, add drg, the revolution of package p is stopped.And meanwhile, make the alert utmost point device (indicator lamp 31) of batch up gear 1 send the alert utmost point, and call operating personal, will begin in a minute resumes operation.
Like this, by making yarn detecting sensor 22 to batch beginning, to comprise that the joint time moves interiorly, just can be in whole coiling process, monitor package p always, batch interruption if find that defect such as surperficial confusion can make at once.Promptly, as shown in Figure 3, though under the situation of synthetic yarns, take place easily, but owing to reason such as the friction drag of yarn y is little, when the present invention's circular yarn beam 32 as shown in arrow 6 is displaced to the phenomenon (fragmentary yarn) of smaller diameter side from the larger diameter side of conical package p, because this yarn beam 32 is in the state that floats from the surface of package p, thereby the detection light L of light-projecting component 23 is blocked just this phenomenon generation of perception at once by yarn beam 32.In addition, those yarns that cut off by tension change, be wound onto the surface of package p, be that so-called tension force cuts off or floats, is phenomenon such as so-called float from package outermost layer 21, instantaneous the perceiving of same energy because of the relation of contact pressure and tension force makes yarn.
Again because yarn detecting sensor 22 is arranged on to import yarn under the side front face side of batch up gear 1 (the promptly) F of package p, thus just can easily detect package p unusually.This is to be formed by following reason, promptly, because it is that the outermost layer 21 of package p was pushed by drum 8 with the structure of installing 1 back side that the yarn detecting sensor is arranged on volume, be in the state that is crushed on package p outermost by the hard waste of generations such as fragmentary wire harness or float or tension force cut-out etc., thereby just difficult the unusual of package p that detect.But, in the time of on yarn detecting sensor 22 being arranged on front face side F, the centrifugal action that fragmentary yarn beam etc. form owing to the high speed rotary that is subjected to package, be in the state that flies out from the outermost layer 21 of package p, thereby it is unusual to detect package easily with yarn detecting sensor 22.And, when sensor 22 is arranged on front face side F, can also detect when knotting because of dual draw cause batch bad.Dual draw be shown in Fig. 4 (a), when knotting the yarn end catch mechanism's (pump orifice) 11 and draw 2 one threads (yarn y up to specification and batched thread segment 33 on package p) from package p, but when this 2 one thread is intactly supplied with knotting device b, knotting device b judges can not tie a knot (beginning to batch) with it as drawing mistakenly again.But, even drawn by dual, when needing only 1 velamen supply knotting device b wherein, knotting device b then carries out common knotting action, and when beginning to batch again, derivative another one thread part 33 is rolled in the package p, forms bad goods thus.Because at this moment indrawn thread segment 33 towards package p surface, thereby can be detected by yarn detecting sensor 22 horse backs as Fig. 4 (b) shown in, from batch up gear front face side F.And as shown in Figure 5, producing end face for some reason comes off, under the situation that yarn 34 that pump orifice 11 comes off this end face when knotting and yarn y up to specification draw together, also can detect the yarn 34 that this end face comes off by yarn detecting sensor 22 with dual drawing similarly.In addition, though, also have hard waste and be involved in, because yarn detecting sensor 22 these hard wastes of perception at once, thereby can prevent that hard waste from sneaking into package p along with the yarn y that carries out batching when beginning again.Set for when yarn is tied a knot, only (knotting has just finished the back) makes 22 actions of yarn detecting sensor when beginning again batching.That is, carry out yarn at pump orifice 11 and pick up action and the time do not detect, like this, can prevent by yarn detecting sensor 22 and perceive the misoperation that yarn y that the front end that is sucked mouthful or pump orifice 11 normally draw from package p causes.
Like this, monitor control mechanism of the present invention be the package in-to-in that only could find in subsequent handling before detecting definitely bad, also can prevent to cause these bad phenomenons, the eliminating of the yarn shortcoming of carrying out with bead scrubber 5 and batch after surface inspection combine, just can in the package production process, eliminate the generation of bad goods fully, can reach the purpose of the quality raising that makes package p.
Except the laser sensor that will utilize laser as the yarn detecting sensor 22, can also use optical sensor that light is dwindled through slit diaphragm etc.Can also not adopt light, as long as can detection line or the structure of shortcomings such as hard waste, whatsoever the sensor of sample can.Though be that yarn detecting sensor 22 is fixed near the front face side F at point of contact 25 in this embodiment, but also can make such structure, that is, be arranged on the top of package p or rear,, often monitor package p surface along with coil diameter increases and along the moving radially of package p.In addition, also be not limited to the yarn detecting sensor as yarn monitoring mechanism, for example usable image is often monitored package p, and package p also is not limited to taper shape, can also be cheese shape.
Fig. 6 represents the 2nd embodiment of the present invention.The package quality control monitor unit of this 2nd embodiment compares with the quality inspection device of above-mentioned the 1st embodiment, mainly following this some different.That is, it is the detection light L that makes yarn detecting sensor 122 from respect to driving the nearer position of drum 108 to tilting by ground configuration light-projecting component 124 and photo detector 123 than distant positions, by support 128 light-projecting component 124 and photo detector 123 being linked into an integrated entity, light-projecting component 124 is configured in conical package guest smaller diameter side and light-projecting component 124 is configured in free end one side that is supported to cantilever-shaped driving drum 108.Below, explain these differences.
The purpose of package quality control monitor unit of the present invention is the surface (outermost layer) 121 of monitoring package p, on this meaning, makes and detects light L from being important by this point near the outermost layer 121 of package p.Therefore, preferably parallel with tangent line 125 basically from the detection light L of light-projecting component 124 ejaculations, but owing to form outer stray light at the detection light of drum 108 surface reflection, thus just as illustrated in fig. 6, detection light L is configured to light-projecting component 124 than photo detector 123 more close drums 108 slightly obliquely with respect to tangent line 125.Promptly, yarn detecting sensor 122 is formed when detecting and just becomes perception state (ON) when light L is blocked by the foreign matters such as outside yarn of outermost layer 122, though light-projecting component 124 has directive property, but detection light L still spreads, when this detects light L and is not blocked and incide 123 li of photo detectors in the drum 108 smooth surfaces reflection that is made of metal by foreign matter, even have foreign matter to exist, can not become the perception state.Be in the present embodiment make light-projecting component 124 directive photo detectors 123 detection light L a little from drum 108 remotely with respect to tangent line 125 bevelled a little.
Light-projecting component 124 and photo detector 123 are linked into an integrated entity by support 128.Specifically, in the outside of the set cover of drum 108 front face side F (Fig. 1 27), the all-in-one-piece support 128 across drum 108 is installed on this body frame 135 of batch up gear 101 vertically, be installed at this support 128 on this body frame 135 of batch up gear 101, light-projecting component 124 and photo detector 123 be set dividually in the both sides of this mount 128.As shown in Figure 1, cover 27 is to be circular-arc plate by the section near the side face setting of drum 108 to constitute, and is to be used for preventing the member that end face comes off.Support 128 as illustrated in fig. 6, by along the lower edge ground of cover (27 among Fig. 1) across the connecting portion at the two ends of drum 108, the two ends that are arranged in drum 108 and the rising portions that erects along the plane of bending of cover (Fig. 1 27), the fixing base portion formation of light-projecting component 124 and photo detector 123 usefulness, by in advance light-projecting component 124 and photo detector 123 being fixed on this base portion and after linking into an integrated entity with imbedding, this support 128 being installed on this body frame 135 of batch up gear 101, installation exercise is simplified, and the optical axis after not installing is regulated.
Though from rectilinear propagation, the symmetry of light, light-projecting component 124 and photo detector 123 are configured in the arbitrary end at support two ends, but in the present embodiment, be the smaller diameter side that light projector part 124 is configured in package p.This is the particularly advantageous configuration of detection that the opposite end emaciated face falls.That is, utilized end face to come off easily character that smaller diameter side at package p takes place; With since the light beam of the detection light L that penetrates from light-projecting component 124 gradually diffusion thereby compare with position far away from light-projecting component 124 near positions, the former has the character higher to the sensitivity of yarn, light-projecting component 124 is configured in the smaller diameter side of batching p.Thus, do not adopt leakage with regard to not coming off end face.
And, in the present embodiment light-projecting component 124 is configured in the free end side of drum 108.That is, drum 108 is supported to cantilever,, light-projecting component 124 is configured on the opposite free end side at fixing distolateral configuration photo detector 123 by this body frame 135 of batch up gear 101.This be because as described above light-projecting component 124 near in the configurations of drum 108, allow the part of the body of light-projecting component 124 to be hidden in 108 li of drums, become obstacle at fixing distolateral, this body frame 135.This is owing to the member that does not have in free end side to disturb, and the configuration of light-projecting component 124 is just free, installation is just simpler.And if drum 108 fixing distolateral set for larger diameter side, the drum free end side is set for smaller diameter side, then the free end side of drum 108 must become the smaller diameter side of package p; Therefore can be configured in light-projecting component 124 smaller diameter side of package p, and on the free end side of drum 108.
