Carton Erectors

Automatic carton erecting machine for American style cartons. Shapes the cartons and seals bottom of carton with hot glue.

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.
