Coiler ( Takeup ) for Aluminium Rod and Flat

Application : For Compact tension controlled winding of Aluminium Rod or Flat on bobbins in synchronisation with the extruder press.Take up will be suitable for rod diameter 8 mm to 26mm and Flat width 10 mm to 30 mm. At the end of coiling it will be safe to handle the product without loosening of coil. Pressure roller is provided to hold the rod / Flat before cutting.

Machine Construction : Coiler will be fabricated construction of heavy design with reel Frame, Bobbin Shaft, drive arm, Traverse assembly, Drive Motor with gear box, Motorised loading and unloading etc. mounted on a common base frame.

We offer the coiler to suit customer requirement – Diameter range and weight of bobbin, Rod diameter, flat size and speed. Bobbin Dimension :

Flange diameter : 1500. (Maximum)
Weight : 1500 Kg.( Maximum)
Width : 1400 mm ( Maximum)
Bore : 100 mm
Material : Aluminium , Aluminium alloy
Rod Diameter: 8 mm to 26 mm
Flat width : 10mm to 30mm
Weight : 1500 Kg ( Maximum)
Line speed : 25 Meters/ Minute

Bobbin Loading : Shaft type with drive arm and pintle. Bobbin is loaded on the shaft and locked in position before loading on to the machine

Loading and Unloading : Motorizedwith AC geared motor and Torque limiter clutch. Proximity switches provided at end limits.

Drive : with suitable A C Motor andReduction gear box. AC variable frequency drive provided for tension control.

Drive Transmission : Chain drive.
Drive arm on reel shaft will be provided with backlash free operation to prevent loose winding.

Speed and Tension control : A C Variable frequency drive provided for automatic speed synchronization with the press speed. Bobbin speed will get reduced automatically during diameter build up. Winding tension can be very finely adjusted with potentiometer

Brake : Disc brake or Electromagnetic brake. Additionally Dynamic braking with DBR.

Traverse Assembly : With Rollring Traverse unit model 4RR60 suitable for 60 mm dia shaft. Pitch and traverse stroke length can be very finely adjusted. Traverse speed is synchronised with bobbin speed. Guide roller assembly with two set of vertical and horizontal rollers are supplied. Tensioning roller assembly with adjustable guide roller on top with handle is provided to hold the loose end of rod after cutting. Guide assembly mounted on a carrier with four number linear bearing LM 40 and two number 40 mm dia guide shaft and the guide carrier will be very sturdy.

Electromagnetic clutch is provided in the traverse shaft drive to disengage the drive and position guide roller assembly suitably for any corrections during winding by rotating the shaft freely with handle.

Control panel : Control panel with ABB, Siemens or reputed make AC Variable frequency drive and accessories will be supplied.

Operating Desk : Provided with Push buttons and potentiometer. Safety Guard: Provided for all drives.
