The Marchesini MC820 is an automatic machine for collation and insertion of single and collated cartons into the case. Case closing with not overlapping adhesive tape.
Balcony design to improve accessibility, maintenance and cleaning operations;
Machine composed of three working sections: cartons collation, case feeding and closing;
Working area and case transport, separated from the mechanics placed on the rear;
Case changeover adjustments in “B” (width) and “H” (height) quotes, are made through servo motors with direct command from the operator panel;
“A” quote (length) automatically managed when setting of the format parameters is made from the PC.
Collation of cartons, coming from the upstream machine, on the infeed conveyor belt;
Pick & Place for the direct transfer of the cartons into the hopper, with vertical stacking from the bottom to the top;
Product pick up detected at each cycle of the collation, to assure that the defined number of products has been collated;
Machine stop in case of wrong pick up;
Product transfer into the case, at the end of the collation phase, by the mechanical command of pusher and hopper.
