The Marchesini MA320 is an automatic continuous motion high speed horizontal cartoning machine. Cartoner suitable to pre‑break and to open either reverse or straight tuck-in three flap cartons, insert product, which has been delivered to infeed, close cartons and discharge.

Main Features

• This Cartoner is designed to satisfy high quality performance, and is built with new technologies and thorough experience in this field. It has the advantage of small space requirements and, at the same time, offers a strong basic structure and high safety performance.
• The basic machine includes the following items:
• In the machine design, GMP norms have been followed and the machine is delivered with the CE mark. The working area is a balcony type layout. A vertical steel panel divides the mechanical machine part, on the rear side, from the working area and carton-leaflet transport on the front (operator) side.
• The cartoning section is composed of two enclosed drive units for carton transport and closing movements, running in oil bath. One section is mounted fix and the other one adjustable and servo motor driven to suit the carton length (“h” dimension). Drive units are chain driven and bevel gears enclosed in boxes with lubrication from oil bath.
• The lower backside of the machine, in a dedicated compartment, encloses the main servo motor and the dry Type BECKER vacuums pump. Vacuum distributions achieved mechanically and locking solenoids. Vacuum for carton and a PIAB Venturi Type pump obtains eventually mounted leaflet pick-up.
• Specially designed sloping surfaces below carry any ejected items towards the operator, collecting them in proper bins. Easy cleaning. Easy clearance of packing residues.
• Leaflet feeding units, if included as optional equipment, are within the safety guard so reducing the noise.
• Easy size adjustments with hand wheel and digital indicators.

Product Feeding

• Product bucket infeed chain designed to be connected to various available automatic feeding units. Simultaneous adjustment of all infeed buckets (related to product width) includes hand wheel and digital indicators. Product bucket infeed chain designed to be connected to various available automatic feeding units. Infeed and discharge height is 860 +/- 50mm.

Cartoning Section

• High capacity carton magazine with pusher belt, standard length 1500 mm (59”), below the product bucket chain, on operator’s side, at 750 mm (29,5”) from floor level, with minimum load control.
• Arms with suction cups take the carton and insert it in an oscillating mechanism, which provides to open and prebreak it at 90 degrees. The squared open carton is transferred into the carton transport lug chain. Simple and adjustable settings of magazine guides and picking phase with digital indicators and millimeter scales.
• A set of shafts with suction cup terminals picks the carton from the drum and transfers it into the lug chain. Simultaneous adjustment of carton transport lug chain (carton width “a” dimension) including digital indicator). Independent tension adjustment for each chain.
• Product insertion into the carton, arriving in a previously loaded bucket chain, achieved with a set of pushers placed opposite the operator side following the continuous motion of the lug chain.
• Servo powered adjustment for change in carton length (“h” dimension).
• After closing, the lug chain transfers the carton to two lateral accelerating discharge belts.

Installed Safeties

• Safety Guard in Methacrylate transparent (see through) material with electric interlocks, safety micro switches and machine stop in emergency mode and release of air pressure.
• Electronic torque overload control on the main motor and immediate machine stop.
• Overload safety on product pushers and machine stop. After clearance, a reset is mandatory and pushers automatically return in working position.
• Machine stop after three consecutive errors.
• No product: no leaflet, no carton. The product presence releases carton and leaflet (if present) pick-up.
• If a missing carton is detected, the pusher is stopped and the product discharged from the bucket chain into a collation bin at machine front side, without machine stop.
• Expulsion of cartons with missing product (and/or leaflet and/or wrong code, if units are mounted) without machine stop.
• Carton expulsion control, checks if the reject was made. If not the machine stops and a reset is mandatory.

Machine complete with:

• Extended bucket infeed chain.
• Easy size adjustments with handwheel and digital indicators.
• Machine complete in all parts equipped to handle one size product and carton.
