Two different types of filled crates are supplied that arrive on two different roller conveyors. The crates are placed in the correct formation on these roller conveyors so that they can be placed on the correct pallet. A stack of empty pallets can be placed with a forklift at the empty pallet position. Also, the robot is equipped with a gripper that can pick up the crates, but also the pallets.
When a layer of crates is ready on the supply roller conveyor, the robot will pick up these crates and place them on the correct pallet. As soon as a pallet is full, the pallet will be discharged and the robot will pick up a new pallet and place it in the filling position.
The pallet roller conveyors of the stacking positions consist of three roller conveyors. The robot will place an empty pallet on each of these roller conveyors, after which the robot will fill the pallets with full crates. When a pallet is, full it will roll away to the "traversewagen". The traversewagen rides back and forth, over a frame, between the different roller conveyors of the stacking positions. The top of the traversewagen is a roller conveyor on which the pallets can stand. When a pallet is full, the traversewagen will move towards this roller conveyor. After this, the pallet will roll onto the traversewagen and move to the top sheet layer. Now the full pallet will roll on the roller conveyor of the top sheet layer.
A layer of foil is placed over the pallet on the top sheet layer. After the top sheet has been laid, the pallet will be transported to the wrapper where the pallet will be wrapped in plastic.
The roller conveyor on which the pallet is placed rotates. At the same time, the wrapping unit will move up and down so that the pallet is neatly wrapped in plastic. When the roller conveyor is in the correct position, the pallet rolls from the roller conveyor onto the weighing roller conveyor where the pallet is weighed. When the pallet has been weighed, it will be provided with a sticker with the pertinent weight.
Now the pallet has been weighed and provided with a sticker, the pallet will be removed and the pallet can be picked up from the roller conveyor using a forklift or pallet truck.
The entire Crate Wrapper consists of:
- Supply roller conveyor
- Empty pallet position
- Pallet roller conveyors stacking positions
- Top sheet layer (Topvellegger)
- Weigh roller conveyor + printer
- Discharge roller conveyor
