Automatic High Layer Stack Production
- Automatic sheet handling from cassettes
- Carrier palettes automatic loading / unloading
- Automatically remove carrier films before stacking
- Automatic vision alignment
- High force pre-lamination press included
- Suitable for high layer count stacks
The ST-series of Stackers were specifically developed for high layers count applications where up to 8
different patterns need to be stacked automatically. These stackers are available in automatic or manual
versions. On these machines the carrier film is removed first, then the sheet is pressed on to a previous one
using relatively low force. After the stack is built up, it moves to the pre-lamination press, where it is pressed
with a higher pressing force. The sheets are handled by a vacuum chuck, so these stackers are not suitable
for components with through-holes or cavities. Stacks up to 12 mm are normally built on a carrier block.
Higher stacks are built in a cavity which prevents the layers from becoming misaligned. Using this approach
stacks of up to 100 mm in height can be made. The stacks are built on a single carrier block.
Up to 20 carrier blocks can be processed from a cassette system. The carrier blocks are loaded automatically
from a cassette and placed back into the cassette after the stacking sequence is finished. On the fully
automatic units the sheets are loaded from sheet holders, aligned by the vision system, the carrier film is
removed and finally they are stacked. On the manual version, sheets are loaded by the operator.
The stacking sequence is fully programmable via a touch screen interface. Two high resolution cameras
controlled by a PC vision system detect the sheet position. A short cycle time and high stacking accuracy
make the ST stackers the best choice for high layer count individual sheet stacking machine available on the
market today.
