Please with reference to Fig. 5 and Fig. 6, each detection agency 34 comprises a body of rod 342, a feeler 344, a spring 346 and a detected element 348.These bodies of rod 342 are rigid rod structure.The body of rod 342 of four detection agencies 34 of these upper plate 31 end faces is parallel to each other and is vertical with the direction of this chute 321.The middle part of these bodies of rod 342 is articulated on the fixed wall 316 of this upper plate 31 through a rotating shaft 3162.This feeler 344 is positioned at an end of this body of rod 342, and this spring 346 and this detected element 348 are positioned at the other end of this body of rod 342.Please with reference to Fig. 5, an end of this spring 346 is connected with this upper plate 31, and the other end is connected with the body of rod 342 of this detection agency 34, so that this body of rod 342 is applied elastic force.These feeler 344 1 ends are fixed on this body of rod 342, and the other end is provided with a probe 3442, and this probe 3442 is the rigid ball that separates with this feeler 344.During work, this four feelers 344 and popping one's head in 3442 are successively set in four through holes 318 of this upper plate 31; Each feeler 344 is replaced through this body of rod 342 by this spring 346 and the probe 3442 that it is corresponding flexibly is compressed on the chain tooth 74 of this chain belt 70 (like Fig. 8 and shown in Figure 9).This induction mechanism 36 is a magnetic inductor, and it is provided with detected element 348 that should four detection agencies 34, and is connected with this mark machine 50.This induction mechanism 36 is used for detecting simultaneously the motion of these detected element 348.When the motion of one of them detected element 348 occurs when unusual, this induction mechanism 36 sends control signal to this mark machine 50, and the strap 72 of 50 pairs of these chain belts 70 of this mark machine carries out mark.
Please with reference to Fig. 4, Fig. 7, Fig. 8 and Fig. 9; When these chain teeth detectors 30 work; This chain belt 70 is at the uniform velocity drawn passes the chute 321 on these chain teeth detectors 30 bases 32; Because the size of this chute 321 is identical with the xsect of this chain belt 70, so this chute 321 will position the chain belt 70 that linearity is moving.Probe 3442 in this detection agency 34 will slip over the surface (like Fig. 8 and shown in Figure 9) of these chain teeth 74 successively under the compacting of this spring 346 and feeler 344.Please with reference to Fig. 7 to Fig. 9, when being positioned at these chain tooth 74 surfaces when this probe 3442, its vertical position is the highest, and the vertical position of detected element 348 that is positioned at these body of rod 342 other ends accordingly is minimum, and this induction mechanism 36 sends normal judgement signal.Then, this chain belt 70 moves forward, and when this probe 3442 slided into the midway of two adjacent chain teeth 74, this probe 3442 received compressing of this spring 346, and its vertical position decline certain distance is so that obtain the support of this two adjacent chain tooth 74; The body of rod 342 that the decline of this probe 3442 drives this detection agency 34 rotates along this rotating shaft 3162; The feasible vertical position that is positioned at the detected element 348 of these body of rod 342 other ends raises: what the variation of this height reflected is normal gap between these chain teeth 74, so this induction mechanism 36 still sends normal judgement signal.That is to say that when the probe 3442 of this detection agency 34 slipped over the normal, chain tooth 74 of continuous arrangement, being judged as of this induction mechanism 36 was normal.
Please with reference to Fig. 7 to Fig. 9; This chain belt 70 moves forward; When the probe 3442 of this detection agency 34 slides into the position of half tooth 74a of this chain belt 70; Because this half tooth 74a do not have shank (as shown in Figure 7), can't support this probe 3442, this probe 3442 will be dropped to the strap 72 of this chain belt 70 by replacing of this spring 346 to contact.At this moment, this probe 3442 drops to its lowest position.This extreme lower position is lower than this probe 3442 residing position between two normal, chain teeth 74 time, and the detected element 348 that is synchronized with the movement with this probe 3442 also moves to the highest point of vertical position.This induction mechanism 36 detects the position of this detected element 348, and sends unusual judgement signal, and the strap 72 of controlling 50 pairs of these chain belts 70 of this mark machine carries out mark.Operating personnel can find the position of this half tooth 74a rapidly according to the mark of this mark, thereby with its removal.Understandable; As long as the distance that this probe 3442 descends surpasses its distance that between two adjacent normal, chain teeth 74, is descended; This induction mechanism 36 all should send unusual judgement signal, because this demonstrates the chain tooth 74 that this probe 3442 contacted tangible fault of construction is arranged.
Through shifting to install of these four detection agency 34 feelers 344, this chain teeth detectors 30 can detect the head of these chain belt 70 1 sides two row's chain teeth 74 and the structure of shank respectively, thereby realizes the complete detection to these chain tooth 74 profiles.Through another group detection agency 34 and induction mechanism 36 is set on these base 32 lower plates 33, this chain teeth detectors 30 can be realized the two-sided detection to the chain tooth 74 of this chain belt 70.
Can know by above narration,, make it possess the ability that the chain tooth 74 to injection mo(u)lding detects in real time because zipper injection machine 100 of the present invention used chain teeth detectors 30 of the present invention.When mass defect appearred in the chain tooth 74 on this chain belt 70, these chain teeth detectors 30 can mark near the strap 72 this chain tooth 74, had promoted the automaticity and the work efficiency of this zipper injection machine 100 effectively, had also reduced operating personnel's work.
Understandable; Because this chain teeth detectors 30 is after this chain belt 70 closes chain, its chain tooth 74 to be detected; Compare and do not close chain and detect, two row's chain teeth 74 of this chain belt 70 are realized mutual support owing to being meshing with each other, and one-piece construction is stablized; Can bear extruding and the distortion that is not shifted of the probe 3442 of these detection agencies 34, have the more accurate advantage of testing result.This probe 3442 also can adopt other line face slide constructions, the roller structure that for example is connected with this feeler 344 etc.The internal diameter of these through hole 318 epimeres is greater than hypomere, and the rotation of this feeler 344 provides and let bit space (as shown in Figure 9) when moving up and down for this probe 3442.This induction mechanism 36 also can adopt the inductor of other types, and for example photoelectric sensor, touch sensor etc. need only it and can detect the whether overshoot scope of motion of a plurality of detected element simultaneously.In addition; This detected element 348 arrives the distance of this rotating shaft 3162 to the distance of this rotating shaft 3162 greater than this feeler 344; Through lever principle, the small size motion of this feeler 344 is converted into the more significantly motion of this detected element 348, thereby improves the accuracy of detection of this induction mechanism 36.Certainly, consider that from saving ground, space angle this induction mechanism 36 also can directly detect the motion of this feeler 344, and the shape of judging chain tooth 74 according to this defectiveness whether.This induction mechanism 36 can not be connected with this mark machine 50 yet, directly sends alerting signal when unusual detecting, and causes that operating personnel note.
Please with reference to Figure 10; It is depicted as another kind of slide fastener chain belt 70a by the zipper injection machine injection mo(u)lding; The difference of this chain belt 70a and this chain belt 70 is; The chain tooth 74 of this chain belt 70a is not arranged on this strap 72 continuously, promptly forms a spacer section 721 but whenever be spaced a distance, and this spacer section 721 is used to install ending up and down (figure does not show) of chain belt 70.Because the existence of this spacer section 721, above-mentioned chain teeth detectors 30 can't be judged the fault of construction of the chain tooth 74 on this chain belt 70a.In addition, in the injection molding process of this chain belt 70a, produced small size depression 741 on the chain tooth 74b, and the degree of depth of this depression 741 is less than these probe 3442 decline degree of depth in two chain teeth, 74 middle.At this moment, above-mentioned chain teeth detectors 30 also can't be realized the detection to this chain tooth 74.
For solving above-mentioned two problems; Please with reference to Figure 11; The difference of chain teeth detectors second embodiment of the present invention and first embodiment is; The induction mechanism 36a of this chain teeth detectors 30a is an optical fibre displacement sensor, and this detected element 348a is to being provided with by induction mechanism 36a, and this induction mechanism 36a is connected with a Programmable Logic Controller 80 (Programmable Controller) through a data line.Be provided with a control program in this Programmable Logic Controller 80.This induction mechanism 36a is used to detect the displaced position of this detected element 348a, and testing result is passed to this Programmable Logic Controller 80.This Programmable Logic Controller 80 is used to judge the detected induced signal of this induction mechanism 36a.Please with reference to Fig. 9 to Figure 11; Because these spacer sections 721 are periodically to occur on this chain belt 70a; So; Can be with one section normal, chain tooth 74 and the one section spacer section 721 that is adjacent as one-period, the induced signal that motion produced of probe 3442 in this cycle of this detection agency 34 as the standard induced signal, is input in this Programmable Logic Controller 80 in advance.During detection, only need induced signals that control program through this Programmable Logic Controller 80 relatively should probe 3442 real-time generations whether to conform to and to accomplish detection this chain belt 70a cochain tooth 74 with this standard induced signal.Because this induction mechanism 36a is an optical fibre displacement sensor, can write down the whole process motion of this detected element 348a, go up the different various defectives of height so can detect this chain belt 70a through this Programmable Logic Controller 80.For the chain belt that does not have spacer section 721 70, only need that one section normal chain tooth 74 is continuously produced the standard induced signal as one-period and get final product.Certainly, this induction mechanism 36a also can adopt the displacement transducer of other kinds, for example the commonly used eddy current displacement sensor of industry, capacitive displacement transducer, magnetic displacement sensor etc.
Please with reference to Figure 12, it is depicted as the stereographic map of chain teeth detectors the 3rd embodiment of the present invention.The difference of the chain teeth detectors 30 of this chain teeth detectors 30b and first embodiment is that this chain teeth detectors 30b is arranged with two detection agency 34b respectively in the both sides up and down of base 32.Below be that example is introduced with two detection agency 34b that are positioned at these base 32 end faces.
Please with reference to Figure 12 to Figure 15, the end face of this base 32 upwards protrudes out and is provided with a fixed wall 329.Each detection agency 34b comprises a body of rod 341, a feeler 343, a spring 345, a motion enlarger 347 and a detected element 349 (shown in figure 14).The middle part of this two body of rod 341 is articulated on this fixed wall 329 through a rotating shaft 3292.This feeler 343 is positioned at an end of this body of rod 341, and this spring 345 is positioned at the other end of this body of rod 341.One end of this spring 345 is connected with this base 32, and the other end is connected with the body of rod 341 of this detection agency 34b, so that this body of rod 341 is applied elastic force (shown in figure 15).Please with reference to Figure 14, this motion enlarger 347 comprises that a driving gear 3472, a follower gear 3474 and amplify wheel 3476.This driving gear 3472 is fixedly connected on the middle part of this body of rod 341, and concentric with this rotating shaft 3292, and the rotation of this body of rod 341 will drive this driving gear 3472 and rotate around the center of circle.This follower gear 3474 is gear structure and its diameter diameter less than this driving gear 3472.One side of this follower gear 3474 is fixedly connected on the center of circle of this amplification wheel 3476, and this follower gear 3474 is articulated on the fixed wall 329 of this base 32 through rotating shaft 3294.This follower gear 3474 is driven rotation through tooth on its outer peripheral edges and 3472 engagements of this driving gear by this driving gear 3472, and the amplification wheel 3476 that is connected with this follower gear 3474 rotates (shown in figure 15) thereupon.This detected element 349 is fixed on the outer peripheral edges of amplification wheel of this motion enlarger 347, and 36 pairs of this induction mechanisms should the detected element setting.This feeler 343 is the rigidity body of rod, and this feeler 343 is provided with probe 3442, and this probe 3442 is a rigid ball.During work, this feeler 343 and popping one's head in 3442 is separately positioned in the through hole 318 of this base 32 (like Figure 12 and shown in Figure 15); Each feeler 343 is replaced through this body of rod 341 by this spring 345 and the probe 3442 that it is corresponding flexibly is compressed on the chain tooth 74 on this chain belt 70.
