AUTOMATIC PLC COILING AND PACKING MACHINE
– Intelligent Coil Winding, Measuring, Cutting, and Film Wrapping System –
1. Functional Workflow
The machine performs the following operations in a continuous and automated cycle:
1.Cable Feeding
- Cable is fed from the take-up system or accumulator (synchronized with the extrusion line or offline pay-off).
2.Length Measuring
- Precision encoder or laser-based length counter ensures cutting accuracy (±0.2%).
3.Automatic Coiling
- Servo-controlled dual-flange winding table forms neat coils with adjustable ID, OD, and height.
4.Auto Cutting
- Pneumatic or hydraulic cutters make smooth and accurate cuts at the preset coil length (e.g., 100m, 50m, 25m).
5.Coil Taping / Film Wrapping (Optional)
- Applies plastic film, stretch film, or PVC shrink tape around the coil for dustproofing and transportation.
6.Labeling / Printing (Optional)
- Automatic label applicator or inkjet printer places product specs, barcodes, or customer branding.
7.Output & Transfer
- Coils are ejected onto a conveyor or stacked automatically for carton packing.
