Flex Inspection Machine (MODEL RIR - 1000)

GENERAL DESCRIPTION

This equipment has been specially designed to rewind printed / unprinted, substrate which has to be processed further invariably this further processing means "value addition" and therefore it is imperative that the printed /unprinted substrate should be subjected to through inspection and rejections, if any due to misregistration / pinholes, while printing / metallizing are removed prior to value addition.

The machine configuration has been depicted in the enclosed drawing and as obvious it essentially consists of:-
a) Floating Unwind Stand. (Half Turret)
b) Main Machine

1. FLOATING UNWIND
The unit consists of a precision machined base, on which are located hardened and ground bearing tracks. The floating platform fitted with four number of bearing can freely oscillate in the machine base. Two side frames are fixed onthe floating platform.

2. HALF TURRET.
A pivot shaft is mounted on bearing locks on top of side frames. An edge guide unit is provided to position the unwind stand as per the reel telescopy. Cast Iron fully machined rewind arms are accurately aligned and permanently fixed to the center pivot shaft, which acts as a fulcrum for unwind arm. A drive train from Powder Brake is housed on the drive side arm.

MAIN MACHINE

The entire machine consists of a fully machined cast iron side frame within which are located suitable number of web support rollers, the web viewing light source box and the rewind station.

Operator's/Inspector's convenience has been kept in mind while designing the web viewing area.

While the operators sits in front of the machine (close to floating unwind stand) the web travels upwards on an incline and the printed matter can be viewed without any strain. Diffused lighting is provided behind the incline in case transparent web is to be inspected.

The rewind shaft is powered through a gear train from a constant torque characteristics variable speed drive. The rewind tension can be controlled by adjusting the braking torque, controls for which are centrally located.
