Operational approach
Fig. 9 illustrates the flow chart that destroys the method for entry needle by the breaking plant of Fig. 4, Figure 10 is illustrated in the sectional side view that drops into the state of useless syringe in the breaking plant of Fig. 4, Figure 11 is the sectional side view that after the useless syringe of input illustrating in Figure 10, driven gear is pushed to the state of rear side, Figure 12 is the sectional side view of the state of entry needle from the needle assembly of useless syringe separates that Figure 11 is shown, and Figure 13 illustrates the entry needle in useless syringe and the contrast axonometric chart of the entry needle that destroyed by the breaking plant of Fig. 4.
First, as shown in figure 10, while dropping into the entry needle 230 of useless syringe 200, intermeshing gear 120 rotates (S10).More specifically, while detection, apply power supply by power supply unit 118 to power part 117 after entry needle 230 is by input port 113 and guide member 113a by sensor 115, power part 117 moves, thus driven wheel 121 and driven gear 120 engagement rotations.
Then, as shown in figure 11, in the time that entry needle 230 enters in gear 120, driven gear 122 is urged and rearward moves (S20).Now, be pushed to rear together with 132 of driven gear 122 and press member 131 and lower limbs, elastomer 133 shrinks, to preserve stronger resilience force.
Afterwards, as shown in figure 12, entry needle 230 passes through gear 120, and separates from 220 of needle assembly 210.Now, enter between gear 120 and during moving down at entry needle 230, the needle stand 220 of needle assembly 210 contacts with guide member 113a, stops it to move down again, thereby entry needle 230 separates (S30) from needle stand 220., entry needle 230 is not destroyed fractures and a part remains on needle stand 220, but is intactly pulled out and separates.
Then, as shown in figure 13, in the time that entry needle 230 destroys and intactly discharges from gear 120 with waveform, driven gear 122 moves forward, and gets back to original position (S40).Now, the resilience force of elastomer 133 makes press member 131 get back to original position, and meanwhile, driven gear 122 is got back to original position together with lower limb 132.Now, as shown in figure 13, entry needle 230 destroys with waveform, and useless entry needle 119 drops in returnable 140.
Afterwards, gear 120 stop the rotation (S50).Now, in the time that useless entry needle 119 is intactly discharged from from gear 120, power supply unit 118 cuts off power supply, and power part 117 is out of service, gear 120 also stop the rotation (S50).
Finally, germicidal lamp 116 is lighted official hour, and the useless entry needle 119 that is housed in 140 li of returnable is carried out to sterilization processing (S60).Afterwards, in the time that returnable 140 is accommodated a large amount of useless entry needles 119, extract returnable 140 discarded from body 110.
