The one futtock spring 337 that sliding sleeve is slided backward combines.Brake 33 structures after the combination are shown in Fig. 9 A.Wherein, chute 3321 on the ram 332 can import for sliding sleeve 333, have a protrusion block 3322 before the chute and be used to stop spring 337, spring holds then contact at the rear wall of sliding sleeve 333 inside grooves 3331 in addition, to force sliding sleeve 333 to slide backwards, but be fixed on fixture block 334 before the sliding sleeve 333 after being subjected to the stopping of ram 332, sliding sleeve 333 can not be slided backward again, keep state shown in Fig. 9 A.Otherwise, if sliding sleeve 333 shown in Fig. 9 B to front slide, after then the microswitch S3 of rear side end and catch 335 touch the block 335 of front end, just make sliding sleeve 333 stop to move ahead, the induction point of microswitch S3 is pressed only at this moment, so can instruct the motor 61 of output device, main pneumatic cylinder C1, secondary pneumatic cylinder C2 to produce action, its course of action can further be subjoined by in follow-up.
Below introduce the course of action of positioner 30, as shown in figure 10, when zipper strip 80 turn right by the drawing left side enter positioner 30 after, sprocket 84 can be kept straight in the Ullage by 316 of two pressing plates, because (sprocket in this district is divested by stripping tooth machine all can to reserve one section no sprocket district 80A on the zipper strip 80, and the length in this district all is certain), so when following brace 3201 bottoms of inductor 320 touch no sprocket district 80A (as shown in figure 11), can there be sprocket 84 because of no sprocket district 80A, and make down brace 3201 under wind spring 321 effect and descend, relatively, with regard to being raised up, foot piece 3202 suppressing induction point S11 under the microswitch S1 of rear end, the main pneumatic cylinder C1 of this moment remains on the journey state (as shown in figure 12) that moves back, so with lifting plug 310 that piece 305 combines is that to be positioned at the valley 3091 of pushing block 309 the next, this can make brake 33 open-shaped (as shown in figure 13), if observe then as shown in figure 14 with three-dimensional section.
It is open-shaped disclosing braking group 33 in Figure 13, Figure 14, but the spacer block 3071 of this moment is to be hidden in the preceding breach 3148 of top pillow 314, and the plain block 3072 that combines with spacer block 3071 one is to be positioned at top pillow 314 times, so when zipper strip 80 advanced, chain cloth 83 and sprocket 84 can not be subjected to the influence of spacer block 3071 and plain block 3072.Cause in brake 33 and can open reason can join Figure 15 A, plug 310 in aforementioned Figure 12 is after moving behind the pushing block 309, can by valley 3091 upper move to the next, related making lifted also together decline of piece 305, this makes and lifts the also together decline of lateral mass 306 that piece 305 combines, so the matrix 331 of brake 33 can be axle center (axle bolt 322 is fixed with top pillow 314) with axle bolt 322, another bolt 323 descends with the decline of lateral mass 306, simultaneously also can be slotted hole groove 3062 in by outside mobile inwardly, owing to forcing matrix 331 and ram 332, moving of axle bolt 323 together upward deflect, so brake 33 is open-shaped.
Figure 15 B is the schematic diagram that expression act piece 305 and lateral mass 306 are formed in one, and this embodiment more can be convenient to assembling, makes assembling more simple and easy.
As shown in figure 16, because zipper strip 80 can continue to advance under the motor 61 of output device drives, can not pass through the contact of brace 3201 down so there is sprocket district 80A, the sprocket 84 that is 80A rear, no sprocket district with that contacts with following brace 3201, but when brace 3201 bottoms touch sprocket 84 or pull head 81 instantly, can be higher than chain cloth 83 because of sprocket 84 (as shown in figure 17) and pull head 81, so brace 3201 is risen, relatively, foot piece 3202 will descend and break away from induction point S11 under the microswitch S1, main pneumatic cylinder C1 can obtain signal and take process action this moment, had as shown in figure 18; After the bar axle of main pneumatic cylinder C1 is with pushing block 309 forward impelling, can make plug 310 extremely upper by the bottom offset of valley 3091, and the act piece 305 that combines with plug 310 promptly together rises, also can rise together with the lateral mass 306 that combines with act piece 305, the height 33A after the rising promptly equals the potential difference 33B of plug 310 in valley 3091; Owing to lift the rising of piece 305 and lateral mass 306, thus can interlock brake 33 and produce closed, as shown in figure 19; Cause in the three-dimensional cross-section structure of brake 33 and can know by shown in Figure 20.
Figure 20 is different with Figure 14, and to be in brake 33 be to be closed, and spacer block 2701 is to protrude on breach 3148 before the pillow 314 of top, after rising, can rest the head on 314 maintenance levels with the plain block 2702 of spacer block 2701 disjunctors again with the top, spacer block 2701 is that this described in detail in earlier figures 4A, Fig. 4 B before platform 270 was fixed on two act pieces 305 with the reason that plain block 2702 can rise; So lift piece 305 in case rise, platform 270 is promptly followed rising, in like manner, to lift piece 305 and descend, platform 270 also can be followed decline.
Secondly, the reason that brake 33 can seal as shown in figure 21, when the plug 310 of Figure 18 after pushing block 309 reaches, can be by valley 3091 the next mobile supreme positions, the related act piece 305 that makes together rises, this makes the lateral mass 306 that combines with act piece 305 also follow rising, so the matrix 331 of brake 33 can be axle center (axle bolt 322 is fixed with top pillow 314) with axle bolt 322,323 risings with lateral mass 306 of another bolt are risen, also can in slotted hole groove 3062, move outwardly simultaneously by interior, last and with axle bolt 322 maintenance levels, because matrix 331 is subjected to the interlock influence of a bolt 323, so can together deflect down with ram 332, so brake 33 is to be closed at last; When the ram in the brake 33 332 is the level of state, the lower dead center 3323 (as shown in Figure 8) on the inboard base of ram can suppressed sprocket 84, so sprocket 84 on the groove 3146 of top pillow 314 not only the right and left stopped by pressing plate 316, the top is then being suppressed by the lower dead center 3323 of ram 332, makes sprocket 84 be subjected to standard and follows route guidance to advance.
See also Figure 22, since about after two brakes 33 descend, two fixture blocks 334 of front end can be (shown in Figure 8 with folder mouth 3341, and be cover off with the lower dead center 3323 of ram 333) bite about two row's sprockets 84, two row's sprockets 84 make sprocket 84 can not pass through folder mouth 3341, so when zipper strip 80 advanced, can drag fixture block 334 and advance, therefore the sliding sleeve 333 that combines with fixture block 334 also can be gone together, and its state is as described above shown in Fig. 9 B.
Other consults Figure 23, when about after the reach of two sliding sleeves 333, be subjected to block 336 until catch 335 and stop with sliding sleeve 333 rear side end, sliding sleeve 333 is not readvanced; And fixture block 334 is when mobile because folder mouthfuls 3341 cooperates up and down with plain block 2702, so sprocket 84 meeting slippages on plain block 2702 advance, until fixture block 334 stop mobile till; At this moment the no sprocket district 80A of zipper strip 80 just in time is positioned at counterdie 41 tops, and about two refinings with an end inner side edge of 83 be positioned at cave 411,412 only directly over (shown in Figure 22), other holds inner side edge only then to be positioned at down directly over 413.
And then, when catch 335 was subjected to block 336 and stops, the microswitch S3 of sliding sleeve 333 rear side end induction contact S31 also can touch block 336, instructs following three parts to move simultaneously so can send signal, is respectively:
