Cable unwinder for reels Ø 600 to 1200mm (max 220kg)

The RBEW14A1 is a cable unwinding machine designed to facilitate the automatic cable feeding process in production lines. It is designed to support heavy loads, reduce downtime, and ensure controlled and uniform feeding, especially in the initial stages of processing (before cutting, stripping, or crimping).

General Features and Functions

The RBEW14A1 serves as an intermediate feeding station.
Its purpose is to maintain stable tension, avoid unwanted twisting, prevent cable slippage, and synchronize output with the line speed.

The base structure is constructed of high-strength steel, providing rigidity and stability to the frame. The machine uses a three-phase motor coupled to a gearbox, with an inverter/speed regulator system that allows the unwinding speed to be adjusted according to line requirements. Tension adjustment is performed via a mechanical mechanism, allowing for fine control of cable tension during extraction.

Operation

1) Spool Loading
The cable spool is placed on the machine's central cylinder, within the diameter range (600 - 1200 mm). The system is designed to accommodate large and wide spools up to the specified size. The RBEW14A1 model, in particular, supports spools up to 680 mm high.

2) Start-up and Adjustments
Once started, the machine sets the base unwinding speed via the inverter/motor. The operator can adjust the cable tension and limit switches to prevent the cable from being overly tight or too loose. The counterweight or tensioning mechanisms help maintain consistent unwinding.

3) Cable Movement:
The machine pulls the cable from the spool smoothly. The motor and gear system provide controlled force, while sensors can detect speed variations or anomalies. If line demand increases, the system adjusts the unwinding speed; if it decreases, it slows down or keeps the wire on standby, preventing breakages or unwanted pulls.

4) Stop
When the reel runs out, sensors or limit switches signal the event, and the machine can automatically stop or switch to another reel. If any abnormalities occur (cable jam, overvoltage, etc.), the system automatically stops operation to prevent damage.
