Operating Principal

  • The cartons are horizontally loaded in the magazine by the operator, pushed into the pick-up area by a pneumatic device. It is possible for the operator to load the magazine during the normal working cycle of the machine, in complete safety.
  • The cartons are picked up by vacuum sucker cups and deposited onto a trolley that brings it to the opening area where it is erected and its bottom flaps are folded by a levers system.
  • Then the carton is moved by two side belts and the glue is sprayed by the guns of the glue unit; a pressing device driven by pneumatic cylinder secures the perfect sticking of the carton bottom flaps.
  • It is possible to adjust the length of the sprays and gaps in between by means of the relevant electronic operator panel.
  • Once formed, the case is transferred by the discharge conveyor to the next station.
  • A maximum queue control photocell on transport conveyors controls the accumulation:when the photocell is engaged, the previous machine stops after a pre-determined time lapse and re-start as soon as the photocell gets free.
  • Tower light signaling the automatic / manual working cycles, the emergency, the machine status.
