As shown in Figure 5, Figure 6, cutting yarn parts 9 is mainly made up of oscillating cylinder 9-1, cutter 9-2, Rodless cylinder body 9-3, stockless cylinder slipper 9-4, connecting plate 9-6.Rodless cylinder body 9-3 is assemblied on turnover board 5-6 bottom surface, stockless cylinder slipper 9-4 can slide along Rodless cylinder body 9-3, connecting plate 9-6 is connected on stockless cylinder slipper 9-4 by screw 9-5, it is upper that oscillating cylinder 9-1 is fixed on connecting plate 9-6, and cutter 9-2 is fixed on the rotating shaft of oscillating cylinder 9-1.The moving direction of cutter 9-2 is parallel to the spindle line of centres, and the pendulum angle of cutter is 0 °～90 °.Cut yarn action while starting, angle be 90 ° to launch cutter, when all the other states, be 0 °, to draw and to protect cutting edge in.

As a kind of improvement of the present utility model, Rodless cylinder body 9-3, slide block 9-4, can adopt the mechanisms such as electronic guide rail to replace.

As shown in Figure 9, moving horizontally parts 1 is made up of base plate 1-1, slide block combination 1-2, screw 1-3, flat-removing air cyclinder 1-4, optical axis 1-5, screw 1-6, optical axis seat 1-7.4 slide block combinations are enclosed within on two parallel optical axises, and optical axis is fixed on base plate by optical axis seat, screw 1-6.Chassis 5-3 is fixed on slide block by screw 4.Flat-removing air cyclinder 1-4 is fixed on base plate 1-1 by screw 1-3, win in succession one end of 3 is fixed on by screw 4 on the chassis 5-3 of Lift Part 5, the other end is fixed on the cylinder rod of flat-removing air cyclinder 1-4 by nut 2 and screw, thereby the cylinder rod of chassis and flat-removing air cyclinder is linked into an integrated entity.In the time that the cylinder rod of flat-removing air cyclinder 1-4 is made stretching motion, will drive Lift Part 5 to the motion of peri position or amphi position, with near or away from spindle: tube drawing is prepared the moment, moves horizontally parts and moves forward to peri position, near spindle position; After tube drawing and the inoperative moment, move horizontally parts and move to backward amphi position, away from spindle position, bump or interfere with headstock, the tailstock of fine spining machine avoiding.

Flat-removing air cyclinder 1-4 of the present utility model, can adopt the mechanical transmission mechanism that motor and leading screw form to replace, and its effect is the same.

As shown in figure 10, the utility model is preferably arranged on automatic doffing dolly, can realize multiple spot and work continuously.Described automatic doffing dolly is mainly made up of upper rail parts 11, lower guideway parts 12, lower guideway pulley part 13, yarn basket 14, dolly framework 15, driving mechanism 16, get on the right track rotor block 17, sensor element 18 etc.The automatic pulling attachment of ring spinning frame cop of the present utility model, driving mechanism 16, the rotor block 17 that gets on the right track, lower guideway pulley part 13 are installed on doffing cart framework 15; Upper rail parts 11, lower guideway parts 12 are arranged on fine spining machine 10; The rotor block 17 that gets on the right track hangs on the upper rail 11-2 of upper rail parts 11, and upper rail 11-2 is arranged on and gets on the right track on bracket 11-1; Lower guideway pulley part 13 leans against on lower guideway parts 12.In the time of the servomotor 16-1 of driving mechanism 16 rotation, be connected to the driven wheel 16-3 rotation on reductor 16-2 output shaft, driven wheel 16-3 engages with the tooth bar 11-3 of upper rail parts 11, dolly is along spindle 21 center line connecting direction walkings, sensor element 18 on dolly detects has walked after predefined ingot distance, servomotor 16-1 stops operating, and dolly stops.Now, the utility model starts action:

The utility model as shown in figure 10 course of work and the operation principle of embodiment is as follows:

1, while initialization, Pneumatic manipulator 7 is relaxation state, and amphi position in the horizontal direction---position is backward away from spindle direction; In the vertical direction upper---the upper end of position in Lift Part; Cutter 9-2 is in left position, and blade is 0 °, in contraction state;

2, after doffing cart is contained on fine spining machine, starting device, AC servo motor 16-1 rotation on trolley driving mechanism 16, the driven wheel 16-3 rotation coaxial with motor shaft, gear 16-3 engages with the tooth bar 11-3 below the upper rail 11-2 being fixed on fine spining machine, and dolly is along the route walking that is parallel to the fine spining machine spindle line of centres;

3, walked after predefined ingot distance when the sensor element 18 on dolly detects, motor 16-1 stops operating, and dolly stops, now, flat-removing air cyclinder 1-4 action of the present utility model, cylinder rod is retracted, Pneumatic manipulator 7 travels forward at horizontal level, arrives peri position, near spindle;

4, lift cylinder 5-1 action, cylinder rod is retracted, and as shown in figure 11, Pneumatic manipulator 7 moves downward in vertical direction to bottom position, arrives the next;

5, the piston rod of gas corpus unguis 7-1 inside moves backward, and Pneumatic manipulator changes clamped condition into, clamps the bottom of cop 20;

6, lift cylinder 5-1 moves again, and cylinder rod stretches out, and Pneumatic manipulator 7 is clamping cop 20 and pulling up vertically upward, as shown in figure 12, move up to upperly, the backing plate at turnover board 5-6 rear portion is contacted with spacing combination 5-11, turnover board overturns then;

7, in the time that cylinder rod extend out to terminal location, as shown in figure 13, Pneumatic manipulator 7 is clamping cop 20 and is turning over, and meanwhile, cuts the oscillating cylinder 9-1 action on yarn parts 9, and blade 9-2 swings 90 °, launches cutter;

8, stockless cylinder slipper 9-4 action, slide block moves to right-hand member from left end, and blade cuts off the tail yarn of cop; Then, slide block moves to left end from right-hand member, and the oscillating cylinder 9-1 cutting on yarn parts 9 moves again, and cutter is drawn in 90 ° of blade 9-2 backswing in;

9, the piston rod of gas corpus unguis 7-1 inside travels forward, and Pneumatic manipulator 7 is returned relaxation state, and as Figure 14, cop 20, in kuppe 5-12 falls into the yarn basket 14 of dolly, completes tube drawing program No. one time;

10, dolly walks on, when the sensor element 18 on dolly detects that after the ingot distance of the regulation of having walked, dolly stops again.Automatic tube drawing device of the present utility model repeats above-mentioned 3～9 action, until all cops of whole fine spining machine are chosen and collect.
