Print Mark Sensor

Print Mark Sensor
This is designed for sensing Registration Mark. It continuously scans the presence of registration mark on the moving packaging film. The electronic circuitary is capable of detecting any colours on any background colour. The scanning rate is as high as 2000 packages / minute making it suitable for any type of packaging machine including candy packing machine.

Working Principle

A modulated, Green LED is focused on the moving packaging film. A highly sensitive Photo cell continuously accepts the reflections from the film (paper / plastic) and sends the signals to the electronic scanning circuit. On scanning the presence of Registration Mark; it gives transistorised output.

A logic controller or digital controllers is also provided which accepts signals from scanning head & other Proximity Sensors to keep correct pouch / bag length by driving correction motor (110V AC, 4 wire) or (230VAC, 3 wire).

Salient Features

Print Mark Sensors With Teach - In Function
Forward Controller

This is with micro controller based technology, wherein user has to press SCAN key (a feather touch key), keeping White spot light on Mark colour as well as on background colour and within 2-3 sec both colours will get registered in memory. The electronic scanning circuit then differentiate both colours and gives out put on detection of Registration Mark.

Forward Controller

Forward Logic Controllers are used in packaging machine along with Print Mark Sensors to control clutch break mechanism.

Forward / Reverse Logic Controllers or digital logic controllers - In most of the FFS (Form Fill Seal) machines, Forward/ Reverse Logic Controllers are used to keep correct pouch / bag length by driving correction motor (110 VAC, 4 wire) or (230 VAC, 3 wire)

FIBER OPTIC SENSOR

FIBER OPTIC SENSOR
Fiber Optic Sensor consist of Fiber optic cable with Amplifier. This is been usedwhere user wants to detect presence of small objects ( opaque / semitransparent ). It is also beneficial where mounting space is the constraint and standardphotoelectric sensors cannot be used. The output from fiber optic amplifier is PNP / NPN transistorized with loadlogic NO ( Light ON ) or NC ( Dark On ) selectable. The fiber optic cable connected to Amplifier can be used in Diffused orThrough Beam mode. The fiber optic amplifier comes in thin 10 mm width housing for mounting on standard 35 mm DIN-rail.
