The specific embodiment
As shown in Figure 1 and Figure 2, the present embodiment seamless underwear machine high speed needle selection control method is:
In needle selection control procedure, on the one hand because inner wear machine each circle that turns round all needs needle selection director data, the needle selection director data that reads in next circle one encloses in advance in the needle selection control centre of the present embodiment inner wear machine, retain three circle needle selection director datas simultaneously, comprise: a upper circle needle selection director data, current circle needle selection director data, next circle needle selection director data, and according to described needle selection director data, in each pin position, all shift to an earlier date n pin and calculate each slide cam selector (in this example, corresponding one group of slide cam selector, 16 pattern bits namely, be that slide cam selector section is 16, n gets 15) needle selection instruction, then in one group of pattern bit in advance, position (i.e. 15 pieces of needle gages) is farthest sent to corresponding slide cam selector by the needle selection instruction calculating, be that needle selection control centre is when controlling current pattern bit group D cutter position, send (D-1) cutter needle selection instruction (this group pattern bit D cutter is 15 pieces of needle gages apart from next group pattern bit (D-1) cutter) of next group pattern bit, when syringe forwards the position of current pattern bit group (D+1) blade to, needle selection control centre just sends next needle selection instruction of organizing this blade (D cutter) to corresponding with it slide cam selector.For example, when the 1st pin (corresponding to each slide cam selector) position, the needle selection instruction of the 16th pin of each slide cam selector is calculated by needle selection control centre, and this needle selection instruction is sent to corresponding slide cam selector; When the 2nd pin (corresponding to each slide cam selector) position, the needle selection instruction of the 17th pin of each slide cam selector is calculated by needle selection control centre, and this needle selection instruction is sent to corresponding slide cam selector; When x pin (corresponding to each slide cam selector) position, the needle selection instruction of (x+15) pin of each slide cam selector is calculated by needle selection control centre, and this needle selection instruction is sent to corresponding slide cam selector; According to above-mentioned rule, calculate on one side, sending on one side, constantly circulation, when (x+15) pin exceeds after total needle amount, since the 1st pin circulation, controls thereby realize needle selection.
