Alumimium Foil Separator - General Description :
The Aluminium Foil separator machine is used to open/separate the paired foils into two rolls of maximum 600 mm diameter. A side slitting system is also to provided with the machine for final material at re-winder. The un-winder stand for particular length of the spool have two side pedestals, mounted on base plate grouted on the floor. Lateral movement of the pedestals is through operation of hydro motors. If needed, a pit can be incorporated for facilitating mounting of coil car. Hydraulic control is through hydro motors for clamping of the spools & centering of the coils.

The loading of the un-winder coil is generally done with the help of overhead crane. This process does not cause any loss in production since running time for light gauge foil (9 micron to 40 micron) with 1200 mm outside diameter is quite long. Maximum line speed of the Aluminium Foil separator is 400 mtr./minute. Therefore generally un-winder coil handling equipment is not provided. However as an option, hydro motor controlled coil car can be provided.

Siemens make Programmable Logic Control (PLC) is provided for the digital DC drives and auxiliary functions.

Roll weight
The maximum roll weight of the substrate roll will be as per input material specification.
( Typically 4000 kg for 1200 mm OD & 1500 mm width)
 
Web guiding unit
This unit ensures that the motorized unwind reel is guided in one operation. It will be designed for accuracy of + /- 100 mm.
 
Draw rollers
This unit will consist of one steel roller & one rubber roller arranged to give “S” wrap having 80 shore hardness. One hydraulically operated nip unit to be provided. The nip units will have independent dc drives.
 
Slitting Unit
This unit will consist of top cutter shaft with blade holders to be controlled manually with a provision for quick and easy change from one slit width to another. The drive to this unit will be common with the draw roller unit.
 
Trimming Unit
It will consist of ac blower having its control on the operator control unit with two flexible pipes to be provided on both sides of the material width and one trim collection unit. The maximum trim width will be 15 mm.
 
Rewind roll unit
It is of differential winding type. The rewinding will take place in controlled condition through individual dc drive. The spacers of different sizes will be provided along with the machine. The maximum diameter of the roll to be rewound and new roll to be spliced in, is 600 mm. The shaft fixing arrangement facilitates quick fixing and removal of the rewind reels.
 
Hydraulic unit
A high resolution hydraulic unit and proportionate control valve are supplied with the machine to control the roll with counter balance facilities, clamping & de-clamping of de-coiler spool as well as re-coiler spool, main nip function & braking system of welding support roll.
 
Rollers
All rollers of the machine is made from aluminium alloy tube duly machined, super finished, hard anodized and with pre & post dynamically balancing for finger touch effect for zero impact on light gauge foil.
 
Main frame work
All side walls and unwind traveling unit are made of fabricated MS plates (box fabrication to avoid vibration). The base frame for the unit is a complete fabrication with heavy duty prime material. All fabricated materials will be stress relieved after
pre machining / fabrication and final machining is done thereafter.
 
Special Features:-Aluminium Foil Separator
All hydraulic cylinders and power packs are housed in the machine above ground level. Therefore there is no need to have any pit arrangement.

Transmission is through timer belts.

Suitable separating angles to prevent web flutter on the rewind side.

Slitting head is located close to the middle drive rolls to prevent web weaving.

All idler rolls are of anodized aluminium and dynamically balanced. Ironing rolls are PU coated.

All motors are generally L&T make and drives are either Siemens or Parker make. PLCs are of Siemens make.

Web guide units are of BST or E+L make ensuring trouble free performance.

The trimmed edges of the re-wound coils are smooth and without any edge tear. The surface of each layer is crease free.

Build up is free of telescoping and creasing. Side weaving does not exceed 0.5 mm.

The good quality and defect free production is subject to entry material quality and availability of skilled & experienced manpower.
