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
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
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,
- Fully solid state thus making it a totally reliable.
- Immune to external light source, electrical interference.
- A selector switch provided to choose Dark switching or light
- High speed switching i.e. 2000 marks / min.
- Detection of different contrast sheds by means of sensitivity pot
Print Mark Sensors With Teach - In Function
|| 12 V DC
/ 24 V DC
|| 3 to 8 mm between
the scanning head and the film
|| High, Low, Open
|| 90 x 65 x 35 mm.
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 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)
Digital Forward / Reverse Logic Controllers are with
built in Production Counter & Speed Indicator makes these Digital Logic
Controllers most cost effective. Available with us is an extensive range of
Digital Forward/Reverse Controllers that are acknowledged for their
attributes of flawless advance design and perfection in functionality. These
qualitative forward controllers come with built in Production Counter &
Speed Indicator, that make these controllers cost effective.
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.
