Daco HSI Slitting / Inspection Machine

  • Daco HSI Slitting / Inspection Machine

The Daco HSI slitting / inspection machine offers both flexibility and high performance. The inspection / slitting machine’s design includes a quick make ready rotary scissor slitting box and colour touch screen HMI operator interface for quick and easy job setup.

Both the rewind and unwind tensions are fully and independently adjustable and has taper tension control as standard. The unwind also has a programmable end of roll function, which allows the operator to select an end of roll diameter.

The slitting machines electronic web guidance system ensures that the finished rolls are perfectly wound, and an inspection table with adjustable splicing table (with pneumatic clamps) is also fitted as standard, enabling splices to be made both neatly and easily.

Pneumatic airshafts for both unwind and rewind means that changing the rolls could not be simpler, and a web advance system makes it easy to attach the web to the core when starting a new roll.

  • Web widths 410mm (16″) and 508mm (20″)

Standard Features of the Daco HSI Slitting / Inspection Machine

  • Unwind
    • Maximum unwind diameter: 1m (40″)
    • 76mm (3″) diameter air shaft
    • Safety chucks
    • Roll lift
    • Merobel electromagnetic particle brake
    • Automatic taper tension control
    • End of roll function – The user is able to program the roll end diameter – slowdown and/or stop – The system does not use any roll followers or external sensors that can be damaged at roll changes. The diameter is programmed from the touch screen operator interface.
    • Web up – the operator can, at the touch of a button on the touch screen operator interface, release the unwind brake to allow for easier webbing up of the machine.
  • Web guide
    • BST electronic web guide.
    • Ultrasonic sensor – enables guiding of opaque and clear materials.
    • Adjustable web guide sensor.
    • +/- 25mm (1″) correction.
    • Integral splice table with pneumatic interlocked web clamps.
  • Draw Head
    • Pneumatically operated silicone nip roller against a driven draw roller.
    • The silicone nip roller does not allow labels to attach themselves to it reducing down time.
    • Fully adjustable via a regulator and gauge.
    • On / off feature to allow for easy webbing up of the machine.
    • Interlocked so that the machine can not be started with the nip roller off.
    • The draw roller is driven by a 1.5Kw (2 hp) motor to isolate the unwind tension from the rewind.
  • Slitting
    • 3 rotary scissor slitting knives (shear knife).
    • Knife separation – Allows for easy setting of the knife and anvil with the web in place.
    • Minimum slit width: 13mm (0.51″)
    • Lateral knife adjustment: +/- 5mm (0.196″)
  • Rewind
    • 1 Product rewind
    • Maximum rewind diameter: 457mm (18″)
    • 76mm (3″) diameter with quick change air shaft
    • Automatic taper tension control
    • Merobel electromagnetic particle clutch
    • Labels in / labels out rewinding
    • The mandrels are quick change. The mandrel size is selected on the touch screen and is electronically compensated for, so there are no gears to change.
    • The rewind is driven by a 1.5Kw (2 hp) motor.
  • Programmable web advance system
    • The web advance delay time is programmable from the touch screen – enables easy attachment of the web to the core when starting a new roll.
  • Count Facility
    • Labels
    • Linear – metres & feet
    • Stop on diameter
    • Total count
    • Batch count
    • Auto calculation of slow down and stop irrelevant of web speed.
    • TLC – Total length count until reset by the operator.
  • Touch Screen Operator Interface
    • Shows machine status – system messages, interlocks not met etc
    • Quick and easy job set ups
    • Counting options
    • Tension settings
  • Speed – 300 metres / minute – 984 feet / minute – dependent on material
  • Run Hour Meter
  • Solid construction – built on a 3mm (0.118″) cabinet with a precision ground steel 16mm (0.62″) main plate.
  • Conforms to CE regulations and all circuits use dual channel safety switches, which are continuously monitored using a certified safety relay.

Optional Equipment

  • Closed loop tension control
  • Missing label detection – 6 or 12 lane
  • Single or double sided anti static bars
  • Twin product rewinds with independent tension control and 457mm (18″) diameter
  • Layon roller for twin product rewinds
  • Razor slitting with lateral adjustment
  • Air mandrels – 25 to 76mm (1 to 3″)
  • Differential rewind shafts
  • Additional rotary slitting knives
