The specific embodiment
By accompanying drawing Fig. 1, Fig. 2 and shown in Figure 3, a kind of automatic winding device of the multi-line cutting machine with swing mechanism comprises that line of cut 3 is around the home on actinobacillus wheel 1; Actinobacillus wheel 1 top is provided with guide roller 4; Line wheel 4 connects escapement 2 through line of cut 3, escapement 2 another guide roller 4 above line of cut 3 connects, and this guide roller 4 connects reels 12 through line of cut 3; Reel 12 belows are provided with bogie wheel 16, and line of cut 3 is connected slave operation roller 11 through reel 12 with bogie wheel 16; Slave operation roller 11 and two active working roll 9 triangular in shape vertically being arranged on the swing disk 10 all are provided with some ring-types coiling grooves 13 on the face of cylinder of slave operation roller 11 and active working roll 9; Escapement 2 connects forks 5, and fork 5 is vertically fixed on the output shaft of tension servo motor 6 forms swing mechanism; Tension servo motor 6 is provided with position control mode and the torque control model that can switch each other down in working order; Reel 12 connects ball-screw 14, and ball-screw 14 connects coiling electric motor 15.Be provided with near switch 17 near the swing disk 10, near switch 17 control swing disks 10, swing disk 10 rotates a week, and ball-screw 14 is done a batch (-type) feed motion with reel 12 in this cycle, and reel 12 advances once and winds the line once.In the coiling groove 13 a undercut secant 3 is set; Slave operation roller 11 is connected many horizontal cut line 3 with active working roll 9 through coiling grooves 13.Two of swing disk 10 is initiatively installed workpiece 8 between the working roll 9, workpiece 8 is fixing by anchor clamps 7.It is that the fulcrum rotation is floated with tension servo motor 6 that fork 5 drives escapement 2, and the compensation cutting machine switches to the error in length and the transformed error of compensation line of cut 3 between reel 12 and bogie wheel 16 of cut mode line of cut 3 from the automatic winding pattern.
The present invention adopts the controller programming, in man-machine interface, operates, and at first selects to press the automatic winding mode button, makes machine get into the automatic winding mode state.This moment, tension servo motor 6 duty was set to position control mode, and pendulum thick stick 5 moves to horizontal level automatically, and was initial point with this set positions.Select the fixing point of coiling electric motor 15 then; Making coiling electric motor 15 drive reel 12 through ball-screw 14 travels longitudinally; When reel 12 moves to slave operation roller 11 with initiatively during the parallel position of working roll 9 article one coiling groove 13; Start the motor of actinobacillus wheel 1, line of cut 3 outputs, as shown in Figure 1; Line of cut 3 is walked around first guide roller 4, escapement 2, second guide roller 4, reel 12 and bogie wheel 16 successively, at last line of cut 3 is wrapped on the first lap coiling groove 13 of the triangle falsework that slave operation roller 11 and working roll 9 initiatively on the swing disk 10 form.The end of a thread with line of cut 3 fixes then.At last, the duty of tension servo motor 6 is switched to the torque control model, and configure the required tension force of line of cut 3 cutting processing parts 8, beginning automatic winding.
Coiling electric motor 15 is triggering signal with what be contained in swing disk 10 next doors near switch; The time of rotating a week with swing disk 10 is one-period; Center line with the last coiling groove 13 is a terminal point; Drive ball-screw 14 and in this cycle, do a batch (-type) feed motion, the reel 12 of ball-screw 14 front ends advances once, and the forward travel distance of reel 12 is that coiling groove 13 slot pitches add 0.5 groove face distance.Then; Pendulum thick stick 5 drives escapement 2 and floats, and line of cut 3 breaks away from reel 12, on bogie wheel 16; Bogie wheel 16 traction lines of cut 3 are pressed on next by slave operation roller 11 with in the coiling groove 13 that initiatively working roll 9 is formed, and guarantee that wire jumper does not take place line of cut 3 and same groove repeats line ball.Reel 12 is retreated 0.5 groove face distance then, guarantees that the distance that ball-screw 14 advances in the one-period is the slot pitch of a coiling groove 13.
Constantly rotate when swinging disk 10, line of cut 3 can constantly be wrapped in the coiling groove 13 of slave operation roller 11 and two active working rolls 9, in all coiling grooves 13, is wound with a undercut secant 3.When debugging, guarantee that slave operation roller 11 and two active working roll 9 corresponding coiling grooves 13 on same horizontal plane, are the level of state to guarantee all lines of cut 3.Initiatively the total length of some coiling grooves 13 will be in the range of movement of ball-screw 14 on the working roll 9 for slave operation roller 11 and two, and the pitch error to ball-screw 14 compensates simultaneously.
After coiling finished, cutting machine switched to cut mode from the automatic winding pattern.Can switch smoothly in order to make automatic winding state and cut state; Line of cut 3 begins should be approximately equal to the length of the coiling that line of cut 3 rotates a circle to swing disk 10 through automatic winding wheel 12, the not poor 10mm that crosses of both errors to the length of swing disk 10 from actinobacillus wheel 1.This error can be eliminated through swing mechanism automatically.Removing method is: 1, tension servo motor 6 duties are set to position control mode, make pendulum thick stick 5 move to horizontal level, and are initial point with this set positions.2, line of cut 3 is enclosed through 12 pairs of slave operation rollers 11 of reel and two active working roll 9 coilings one.3, tension servo motor 6 is switched to the torque control model, the tension value of setting line of cut 3 is 30N.4, eliminate the error that switches to cut mode from the automatic winding pattern through the rotation of actinobacillus wheel 1.The computing formula of the angle that actinobacillus wheel 1 motor output shaft rotates is:
α=sgnxlxβ/2r
Wherein: α is an actinobacillus wheel motor rotational angle,
L is a tension force pendulum thick stick length,
β is a tension force pendulum thick stick deflection angle, reads from the absolute value encoder that the tension servo motor carries,
Sgn is a sign function; Control actinobacillus wheel rotation direction satisfies:
.
The present invention is drawn to swing disk 10 opposite sides with line of cut 3 after coiling is accomplished, line of cut 3 is through bogie wheel 16 outputs of this side.
