This cartoner is designed for the automatic erecting of double-wall cartons and their automatic bottom stapling. Double-wall cartons are stronger and can carry heavier weight and stapling them even more improves carton stackability and keeps better their shape.
The flat preformed cartons with joint side glued are loaded manually into the cartons magazine where they are automatically separated. The machine is designed to be adjustable for different carton sizes.
The carton is transferred into the erecting section of the machine using a wheel-pressing system. The carton is moved till it reaches the end position sensor, then the wheels stop rolling and the carton moves by inertia until it hits the stop plate.
With the help of the upper suction system, the flat carton is erected in an upright position. Under the carton, it is held by lower suction cups so that the carton retains its rectangular corners.
Using the flap closers, three bottom flaps are folded inwards. The fourth, upper, flap is closed when the stapling head is moving down toward the carton.
When the pneumatic stapling system moved at to the stapling position against the folded and closed carton flaps, it staples the carton bottom at two positions. The depth of the staple penetration and tightness of the staple clinch can be adjusted for different carton wall thicknesses.
The perfectly formed and stapled cartons with one side open are taken with the suction cups system ad moved to the output section of the machine where the vacuum is released and the carton is dropped.
Stapling of bottom flaps can be replaced by sealing with hot glue
