Figure 1-2 Snugger Assembly
Each APC module consists of:
• Board Support and Snug Plate (fixed on the front rail)
• Mid Plate housed in the Machined Body.
• Over the Top Clamp
• Foil Assembly
NOTE
Only items detailed in the Replacement Procedures section of this Chapter are
user serviceable. Any attempt to disassemble parts invalidates all warranty
agreements. Modules must be serviced by a suitably qualified ASM trained
engineer.
Board Support and
Snug Plates
The board support, supports the product while it is in the tooling area of the
machine. The rear rail drives toward the front rail, enabling the rear snug plate
to “snug” the product. If a product is a shape that does not have parallel sides
the snug plate in the rear APC module pivots to accommodate it. On the front
rail this plate is fixed and does not move in the Y axis.
Mid Plate Two clamps (per module) hold the mid plate in place during printing. Print mass
up to 20kg or 200N can take place. The clamps are pneumatically actuated to
open and close.
Over the Top Clamp The over the top clamp provides the top clamping of the product. The top clamp
has a range of movements, up and down using double-acting pneumatic
cylinders and forward and back in the Y-axis using pneumatically actuated
double acting slide tables.

ALL PURPOSE CLAMPING (APC)
OVERVIEW
Chapter Issue 1 Nov 16 All Purpose Clamping (APC) Manual 1.5
The MTR system has a programmable width conveyor system, set by the board
width parameter, in the product file. The rails transport the board, using belts,
from the upline machine into the printer, where the board is transferred, using
the same belts, to the downline machine.
MTR offers system modularity; the centre section, which holds and locates the
product, can be removed to accomodate any future upgrades, without having
to replace the complete transport system.
The transport rails have three sections; end rails, mid rails and centre section.
End and Mid Rails In both end and mid sections, there are two screws under the board guide which
attach the rail body to the chassis. The chassis is attached to the rising tables
rail support by the transport legs.
During board transport the mid rail board guide lifts; for printing, the mid rail
board guide lowers. A pneumatically driven piston is used to lower the board
guides; the mid rail screws have an outer guide sleeve fitted to allow this
movement. Two springs raise the guides to the transport (up) position.
Centre Section The centre section is used for holding the product securely during printing. This
section is modular, and it is designed to allow for a variety of clamping arrange
-
ments. Currently, the centre section houses the APC arrangement.
