The Natgraph Automatic Sheet Stackers are completely self-contained with their own drive motor, air blower and hoist.
Available in a variety of sizes, this unit is extremely efficient and versatile with special versions able to accept up to 8,000 sheets per hour. The hoist is chain operated with a reinforced steel base plate with a ramp front.
Fully integrated control to the dryer – remote start/stop, speed following, alarm reporting and stack full warning to control stop the press automatically.
A colour CCTV system can be fitted to all Natgraph dryers, this system includes a free-standing, post-mounted camera above the stacker and a dedicated TV monitor mounted on a fully adjustable stand above the infeed of the dryer. This allows the operator to see the stacker without leaving the printing machine, which is very important when operating long, high speed, fully automatic printing lines.
This feature allows a large or small pile of the printed substrate to be removed from the stacker without interrupting the printing cycle, therefore allowing continuous operation.
This consists of a pneumatically operated support ‘gate’ that provides temporary sheet support to approximately 60mm of substrate height whilst the stack below is unloaded.
