The course of work is as follows:
During start, control system is controlled left density stepper motor 18, right density stepper motor 17, upper elevating cam control motor 20 and 19 runnings of lower elevating cam control motor, seek initial initial point, when arriving initial initial point, each origin position switch 27,28,29,30 is sent respectively the origin position signal, and head 53 was finished and resetted this moment; Right density stepper motor 17, left density stepper motor 18, lower elevating cam control motor 19 and upper elevating cam control motor 20 are regulated left density triangular 3 under the control of control system, upper elevating cam 7, lower elevating cam 8, right density triangular 10 enters the duty that the user sets, during normal operation by right density stepper motor 17, the density that left density triangular 3 and right density triangular 10 are controlled braided fabric is regulated in 18 controls of left density stepper motor, selected by slide cam selector 54 when having knitting needle to change duty, add workspace (or the district that deactivates), when detailed process is start, drive Timing Belt 45 promotion displacer assemblies 42 by stepper motor 44 and seek initial point by slide cam selector support 41 driving slide cam selectors 54 in slide rail 43 operations, send signal by the origin switch (not shown) after finding initial point, drive slide cam selector 54 by 44 runnings of system's control step motor again and arrive the wait work of first job position, when having new knitting needle to add work, by needle selection electromagnet 68 pulling driving levers 69 driving needle selection heads 61 knitting needle is pushed workspace (namely turning over the pin needle track) and work; When having knitting needle need to deactivate state, drive 67 runnings of linear stepping motor screw mandrel by linear stepping motor 65 runnings, linear stepping motor ring flange 66 is slided on linear stepping motor screw mandrel 67, thereby dragging withdraw of the needle hook part fills 71 and moves in slide cam selector section fills 74 rectangular open slot, withdraw of the needle hook part fills the 71 promotion withdraws of the needle and colludes trisquare 73 operations, when the withdraw of the needle projection 731 that colludes trisquare 73 when the withdraw of the needle runs to rear position push rod 64, because inclined-plane, push rod 64 upper end, rear position is withdraw of the needle projection 731 dorsad, rear position push rod 64 rotating shaft around oneself under the extruding of withdraw of the needle projection 731 is rotated, thereby the rectangular groove of retraction is interior so that trisquare 73 straight-line passes are colluded in the withdraw of the needle, when the withdraw of the needle projection 731 that colludes trisquare 73 when the withdraw of the needle runs to front position push rod 63, inclined-plane, 63 upper end is towards withdraw of the needle projection 731, because front position push rod 63 is propped up by the end wall of rectangular groove and can not rotate retraction, then continued operation by the inclined-plane jack-up of front position push rod 63 upper ends, drive the withdraws of the needle and collude 62 and skip to the knitting needle front from the knitting needle back of the state of will deactivating so that trisquare 73 is colluded in the withdraw of the needle, will the deactivate knitting needle of state of lower backward drive begins to return, when touching front position push rod 63 it is depressed, and continued operation by rear position push rod 64 jack-up, drive the withdraws of the needle and collude 62 and skip to the knitting needle back from the knitting needle front of the state of will deactivating so that trisquare 73 is colluded in the withdraw of the needle, lower backwardness comes off from the knitting needle of the state of deactivating and returns, and finishes a withdraw of the needle job.
The duty of then regulating upper elevating cam 7 and lower elevating cam 8 by upper elevating cam control motor 20 and lower elevating cam control motor 19 (namely goes up elevating cam 7, the distance of lower elevating cam 8 and needle-bar 52), be used for need selecting pin kind (the high pin pin of work, middle pin pin, low pin pin) enters knitting needle needle track 82 and participate in knitting, promote to turn over 23 controls of pin elevating cam guide pillar and turn over pin that pin elevating cam 14 turns over pin to needs and push and turn over pin needle track 81 by turning over pin elevating cam Self-retaining electromagnet 21 when turning over pin fully, when knitting needle passes through left depressing cam 2 or right depressing cam 13, knitting needle produces vibration and opens the knitting needle pin and be stamped the pin work of turning over that is beneficial to, and promotes depressing cam guide pillars 26 control depressing cams 6 by depressing cam Self-retaining electromagnet 22 and selects to turn over knitting needles in the pin needle track 81 work (shown in Fig. 7 a); Have and turn on a small quantity pin and by needle selection head 61 knitting needle that will change duty is pushed when (perhaps adding pin) and turn over pin needle track 81 workspaces and carry out and add pin or turn over pin work that (knitting needle of knitting needle needle track 82 is just selected by left needle selecting cam 1 or right needle selecting cam 11 as long as push 3MM by needle selection head 61, pushed and turned over pin needle track 81), the knitting needle that does not turn over pin passes through in connecing pin needle track 83, does not participate in knitting (shown in Fig. 7 b); Knitting needle is brought up to the coil molding that a unification highly is conducive to slide cam selector 54 needle selections and fabric to knitting needle during by left elevating cam 5 or right elevating cam 12.
This computer flat knitting machine has been realized separating of slide cam selector and head, make the mechanical structure of head more succinct, volume and quality have reduced more than 1/2, head is more light, operation inertia reduces, for the high-speed cruising of machinery and level and smooth reverse tune process provide condition, speed can reach 1.5 meter per seconds, and Acceleration and deceleration time is shorter when making head reverse.
Slide cam selector separates with head, also makes the stroke of head no longer need high accuracy, and driving can not used department to take control system and use variable frequency regulating speed control; Make needle plate that stitch need not be installed, the width of needle plate and common hand knitting machine needle plate width reduce integral mechanical structure always, have reduced the machinery production cost, make control system become more succinct.
This New-type computer straight-bar machines is novel turn over pin mechanism mainly by: density triangular, needle selecting cam and lower elevating cam form, and slide cam selector cooperates and turns over pin, turns over the pin needle track and separates with the knitting needle needle track, and structure is more simple.The function triangle all adopts step motor control, but triangle height Set arbitrarily, and support to use the extra-high-speed pin, need not mechanical adjustment.
Above disclosed only be a specific embodiment of the present invention, still, the present invention is not limited thereto, the changes that any person skilled in the art can think of all should fall into protection scope of the present invention.
