Need

As speeds of machines go up, there is a need for the downstream to follow, reducing labour cost.
The main purpose of this machine is to place flat sheets and trays.

Using flat sheets (plastic or carton sheets) is still the easiest way to automate and reduce the operator intervention time. The DPP101 allows you to feed in a complete pallet of flat sheets or trays, which the outfeed conveyor feeds into the palletizer one by one. As a result, you can maximize the time spans between two interventions of the operator.

 

The machine

The DPP101 has one warehouse. The gripper grabs a flat sheet or tray from the warehouse, and places it on the outfeed conveyor towards the palletizer.

Moreover, this unit has an anti-sticking system to ensure feeding in one tray at a time only. It grabs and releases the sheet in a special way to ensure this. After all, sticking is a common problem when using flat sheets. This can have different reasons, like humidity from cleaning, dirt, static charges between the sheets…

Furthermore, the machine has a centering system as well. Misalignment is typically caused by sticking: when the vacuum gripper grabs a flat sheet and the next one is partially sucked along (due to adhesion forces). As a result, the sheet often falls back onto the stack, causing the sheets to be misaligned (not neatly stacked). As the suction cups are mostly towards the middle, the gripper would obviously not detect the misalignment, so the sheet would be placed anyway, not aligned. This is often the cause of fallen bottles on the edges (because there’s a gap) on pallets. Therefore, the centering system is very useful to avoid this!
