Stacker

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.

Options are:

CCTV Monitoring System

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.

Continuous Operation

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.

The Static Elimination System prevents attaching to conveyor and dispersion of finished goods

Collection Tray

The Natgraph Sheet Collection Trays have been designed to operate with all the Natgraph dryer sizes, as well as other makes of the dryer.

They are of steel construction, with a heavy-duty framework and fabricated sheet tray. The sheet tray has a moveable sheet stop to accept different paper sizes whilst the stand is adjustable both in height and angle. The tray can also be tilted to either side so the substrate will fall that way.

Options are:

Air Blower

An optional air blower tube can be fitted to aid in the delivery of larger or heavier substrates.

Vibrating Tray

A vibrating version is available which will ‘jog’ the substrate into a neat stack.

Conveyor systems

PTFE coated fibreglass – 4mm or 2mm
Solid weave for substrates prone to marking
Roller conveyor – glass/wood
Stainless steel ladder – automotive/hydrogen processing
Other conveyor systems are available on request

Vertical integration ensures we can produce bespoke equipment such as this reel-to-reel web dryer which uses Natgraph designed air floatation for minimal contact with the substrate.
