Embodiment
Referring to Fig. 1, Fig. 2, this automatic coil winding machine is made up of main frame, wire-arranging mechanism, payingoff mechanism, computer control four parts.Main frame 1 adopts frequency control, simultaneously foot controller 17 is inserted frequency converters, changes the output frequency of frequency converter by the position of foot controller pedal, thus can utilize the foot controller main control system unlatching, stop and rotating speed.Control system adopts PLC or computer control, according to predefined coil data, and the real-time follow the mode that the action of main control system and winding displacement, payingoff mechanism move to main frame.Whole coiling process is all by computer control, and the operator changes threading speed with foot controller at any time as required or stops, opening.Wire-arranging mechanism is by servomotor 15, compositions such as ball wire bar pair 14, line slideway auxiliary 13, winding displacement dolly 6, winding displacement arm 3, guide wheel system.Guide wheel system is made up of separated time wheel 8, wire-crossing wheel 4, fabric wheel 5,7, glass pulley 2, and each position of taking turns is seen shown in Figure 1.Lead comes out from payingoff mechanism during coiling, earlier through separated time wheel 8 line is separately occurred intersecting when preventing at the same time around two lines, through wire-crossing wheel 4 lead is carried out Primary Location afterwards, again through glass pulley 2 accurately behind the location around to coil 16.The groove width of wire-crossing wheel 4 and glass pulley 2 is according to different adjustment of wind the line rule.Fabric wheel 5,7 lays respectively at wire-crossing wheel 4 and separated time is taken turns 8 oblique uppers, and its purpose is and guarantees the wire casing that line falling or anxious stopping time lead can not break away from guide wheel system.Above-mentioned guide wheel owner will act on and be to guarantee lead when coiling, and the location accurately and reliable and stable during particularly high speed winding.
Payingoff mechanism partly is made up of horizontal walking mechanism 12, tension control mechanism 10, line falling mechanism 11, damping 9 etc.
Glass pulley and wire-crossing wheel structure are adjusted groove width by fast pulley 21 and the helicitic texture that moves wheel 19 as shown in Figure 3, and be with locknut 18 fixing positions of moving wheel 19, locking with oblique outer ring 20.Tiltedly the structure of outer ring is seen Fig. 4, has the seam of a treaty 1mm on it, with bolt sealing is tightened during work, and oblique outer ring can't be rotated, thus when solving the big wire gauge of coiling well owing to nut relatively rotates the problem of becoming flexible.
Tension control mechanism is made up of pneumatic caliper brake 33 shown in Figure 6, ultrasonic sensor 34, cylinder 28, fork 30, guide wheel 31, pneumatic proportional valve etc.Ultrasonic sensor 34 is positioned at drum 32 belows, detected drum 32 actual storage wire diameters every 5 seconds, again by PLC control solenoid-operated proportional valve regulation output pressure, the frictional force that the pneumatic caliper brake 33 of corresponding change produces, thereby the substantially invariable purpose of realization wire tension.Lead with permanent tension force comes out from drum, arrive the wire-arranging mechanism of front behind the upper and lower guide wheel 31 of pile warp again, guide wheel 31 is installed on the axle of fork 30, fork is connected with cylinder 28 by connecting plate 29, when high speed winding or anxious stop, when opening, can produce bigger vibrations or impact to lead, these vibrations by guide wheel, fork, connecting plate pass at last cylinder spool on, cylinder axis changes according to pressure automatically and stretches, thereby realizes damping and keep lead cabling purpose stably.
Line falling mechanism is made up of magnetic powder cluth 35, synchronous belt 36, line falling motor 37 3 parts as shown in Figure 7, and magnetic powder cluth 35 1 brings out an installation shaft of connection drum 32, and other end shaft links to each other with the line falling motor by being with mechanism synchronously.Earlier sent to instruct to electromagnetically operated valve by PLC during line falling pneumatic caliper brake 33 is unclamped, line falling motor 37 starts subsequently, and magnetic powder cluth 35 energisings drive drum 32 revolutions, thereby realize the purpose of line falling.Because magnetic powder cluth has permanent torque and can slippage work, thereby the rotating speed of drum 32 can follow the rotating speed of main frame automatically and phenomenons such as loose ends or motor rotation blockage can not occur, solves multiple conducting wires preferably and falls around synchronous problem.
