RKZ-22
Automatic unit packaging machine in wrap around case. Cases are glued from flat cardboard blanks, then formed and wrapped around a group of products.
The purpose of the wrap-around case packaging system is to count the desired number of unit packages in a specific configuration and seal them in a case.
-
- Forming wrap-around cardboard and open tray from flat cardboard cuts
- wrap-around carton warehouse, for manual insertion of flat cardboard cuts – warehouse length ~800mm
- The time needed to change-over the machine to a different format is approximately 40-60 minutes
- The machine is adapted to the following types of master carton - wrap-around and open tray
- Index carton feeder with stations: feeding, filling, forming and closing the case
- Vacuum generator for feeding blanks from the carton magazine
- PLC control with a color touch panel on a rotating arm
- FESTO pneumatics
- SICK sensors
- Productivity up to 20 cartons/min.
Grouping system:
- A section of conveyors that shoot the product at the appropriate speed into the grouping system
- Grouping system: placing individual products vertically and counting them via an index conveyor
- Pushing the product from the index conveyor in the desired quantity and creating groups via the comb driver mechanism
- The comb driver mechanism is equipped with an anti-collision system based on FESTO pneumatics
Cartoning system:
- Feeding blanks from the carton magazine using an electric arm with vacuum suction cups
- Moving a group of products into a preformed case using a servo motor driven feed arm
- Feed arm equipped with a mechanism for squeezing a group of products using a FESTO pneumatic drive
- Applying a glue path to the upper flap of the box using an electric drive mechanism with a glue gun
- Applying a glue line to the side flaps while the cardboard is passing through
- Closing the walls of the box using the closing head
- Sealed gluing support system equipped with vacuum suction cups
- Discharging finished cases from the cartoning section onto a short outtake conveyor
- Sensors detecting the correct sealing of the carton (only lower side flaps), after detecting an unglued carton, the machine goes into auto stop, triggers a light and sound alarm and displays an appropriate message on the HMI panel
