Automatic Wire Coiler and Strapping System

The automatic wire coiler, also known as a winder, is a specialized device engineered for wrapping materials like wire onto spools or bobbins. When integrated with a strapping unit, it creates a complete automated system for coiling and securing wire.

This equipment is designed for high efficiency, streamlining the winding and strapping processes to significantly increase productivity, saving both time and labor.

SHJLPACK offers comprehensive solutions for the wire industry, focusing on automating post-production tasks. The development aims to address challenges such as labor shortages and inconsistencies in coil formation.

Technical Features

The automatic wire coiling and strapping machine system is built with advanced technology to meet industrial requirements.

• Suitable Wire Diameter: Customized to specific production needs.
• Maximum Speed: Capable of processing wire at speeds ranging from 200 to 800 meters per minute.
• Center Height: The machine's center is positioned 1000mm from the ground.
• Supply Voltage: Operates on 380/440 VCA, 60Hz.
• Coil Information: Adaptable to customized coil specifications.
• Production Speed: Achieves up to 40 coils per hour with a double-head setup, or 20 coils per hour with a single head.

System Components

The complete automated line typically comprises several integrated units:

Vertical Tension Wire Accumulator

This unit manages the wire tension before coiling, ensuring a smooth and consistent feed.

• Frame: Constructed from assembled and welded steel plate.
• Power: Driven by a reducing-speed motor.
• Tension Adjustment: Allows precise tension control for winding. Tension is regulated by a tension control cabinet (DC-24V power). A meter indicates the current tension level. A synchronous device automatically adjusts take-up speed to prevent wire overstretch or breakage.
• Accumulating Length: Stores 5m to 20m of wire.
• Safety Features: Equipped with limit switches at both ends. The machine stops automatically in case of wire breakage.
• Anti-collision: Utilizes a compression spring mechanism.

Automatic Coiling Machine

This is the core unit for forming the wire coils, such as the SH-PCL-W800 model.

Key Features:

• Features two coiling heads for continuous operation.
• Automates the wire feeding, winding, and cutting steps.
• PLC system allows storing and recalling wire coil specifications for quick changeovers.
• Includes an automatic alarm function to signal errors.
• Wire conveyance is managed by a clamp mechanism.
• Length control unit is accurate to 0.01m, automatically reducing speed as the target length is approached.
• Servo motor controls traverse movement, synchronized with the bobbin motion.
• Operator interface includes a touch screen, speed adjustment buttons, and an emergency stop switch.

Machine Details:

• Length Meter Counter: Features an adjustable encoder wheel for precise length measurement (to the centimeter). Wheels are made of durable, treated material (sprayed aluminum alloy/ceramic), with a PU-covered lower wheel to protect the wire. A single-direction bearing prevents wire inversion.
• Winder Head: Provides automatic wire infeed. A servo-controlled dispenser shapes the coil. The winder head starts and stops precisely for winding and strapping positioning. It automatically stops take-up when the pre-set length is reached, followed by the coiling head opening.
• Traverse: Moves the winder head under computer and servo motor control.
• Portal Cutter: Automatically cuts the wire when the pre-set length is reached. The cutter is made from special steel, vacuum-heated for high hardness and long lifespan.
• Control System: Operated via HMI and PLC. Winding parameters like length, coil width, alarms, and speed are set here. IOT features can provide monitoring capabilities. Operators can adjust wire length, diameter, and speed while the machine is running.

Automatic Coil Strapping Machine

This unit automatically applies and secures strapping around the finished coils.

The strapping machine dispenses, tensions, and seals polypropylene (PP) strap while the coil is in position. It uses a heat weld joint. The motor powers off automatically when the strap is inserted.

Key Features:

• Performs strapping through the coil's inner diameter (ID).
• Program control synchronizes both coiling and automatic strapping processes.
• Includes automatic positioning for different coil sizes.
• Strap tension is adjustable for varying coil requirements.
• Connects directly with the coiling machine.
• Features a taper roll with lifting and lowering function for coil handling.
• Capable of applying 3 to 6 straps per coil.

Technical Data:

Parameter	Specification
Strap Width	10mm
Strap Thickness	0.8mm
Type of Strap	PP
Strap Quality	Smooth / High-quality PP
Type of Joint	Friction - Vibration
Joint Location	Front part of the wire coil
Joint Efficiency	Approx. 75-80% of strap breaking load

Machine Details:

• Strapping Head: Designed for radial (ID) strapping of coils with PP belt, performing the entire process automatically after coil positioning. It is fixed in position, integrated with the coiling machine.
• Strap Belt Accumulator: Manages the PP belt unwinding from the pay-off stand, accumulating the belt. Movable wheels provide feedback on belt feeding speed to the pay-off stand.

Automatic Wire Coil Unloading Machine

This automated device removes the strapped wire coil from the coiling head and places it in a designated collection area.

Technical Data:

• Program-controlled automatic operation.
• Automatic positioning based on settings.
• Uses a crane and guide rail system for smooth movement.
