Below we describe the logistics system phases needed to replace wooden pallet with a plastic pallet. Vice versa, operation can be managed via PLC with adequate programming.
1.The operator, equipped with a forklift, positions the wooden pallet with the product on the loading / unloading roller conveyor. The wooden pallet with the load crosses the muting safety barrier and is positioned on the roller conveyor.
2. The system conveys the wooden pallet with the load from the roller conveyor to the rotating table. The operator, thanks to the hydraulic fifth wheel placed under the rotary table, can change the orientation of the workstation from position to position.
The operator can also adjust the height of the workstation thanks to a system of hydraulic cylinders positioned under the rotary table. In this way the operator is able to perform the manually removing of the film from the product.
3. Once the film removal operations have been completed, the wooden pallet with the load crosses the muting safety barrier and is conveyed by the system from the position rotary table to the roller conveyor.
4. The separation door equipped on the spraying booth opens and the wooden pallet with the load is conveyed inside the spraying booth on the roller / chain exchange conveyor.
After closing the separation door, the spraying cycle takes place.
5. At the end of the spraying cycle, depending on the selected pallet, a plastic pallet is released from the pallet magazine or onto the catenary while the separation door positioned on the side of the spraying booth opens.
6. The plastic pallet passes through the separation door and is conveyed by the catenary inside the spray booth, onto the roller / chain exchange conveyor where it is aligned with the wooden pallet with the load stationed on the conveyor.
After closing the separation door, the pallet change cycle begins:
– The shutter low down and the Master Inverter pressers close in order to block the wooden pallet and the load.
– The conveyor is raised thanks to a hydraulic system in order to compensate for the difference in height between the wooden and plastic pallets.
– The Toppy Master Inverter transfers the load from the wooden pallet positioned on the conveyor to the plastic pallet positioned on the conveyor.
– The shutter is raised and the Toppy Master Inverter pressers open releasing the load on the plastic pallet while the conveyor is lowered.
7. The dedusting cabin’s door opens in order to let the plastic pallet be transported from the conveyor to the roller conveyor.
8. The separation door closes. The plastic pallet with the product crosses the muting safety barrier and is conveyed from the roller conveyor to the loading / unloading roller conveyor, waiting to be removed by an operator equipped with a forklift. At the same time, after the separation door is closed, the separation door positioned on the side of the pulverizing cabin opens, and the empty wooden pallet is transported by the roller / chain exchange conveyor to the catenary. Depending on the selected pallet, the empty wooden pallet is then stored inside the wooden pallet stacker or while the separation door closes.
