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.

Pneumatic
Manifold and
Node 5
The pneumatic manifold assembly contains the module regulators, operational
valves and driver board for all APC pneumatic functions. See the APC Control
section for more detail.
Magnetic Tooling
Pins
Tooling pins used on modular transport rail (MTR) machines, have a lower
shoulder than standard tooling pins. Magnetic tooling pins (p/n 112069) must
not be used on machines fitted with MTR rail systems. The tooling pins used
for MTR systems (p/n 202582, 217328 or 217329) may be used on all transport
rail systems.
CAUTION
MAGNETIC TOOLING PINS. Clash damage may occur if the incorrect tooling
pins are used on modular transport rail (MTR) printers.

OPERATIONAL MODE SEQUENCES
Chapter Issue 1 Nov 16 All Purpose Clamping (APC) Manual 1.7
OPERATIONAL MODE SEQUENCES
The APC has three operational modes; Snug, Clamp and Snug and Clamp. The
following sections detail the movements and events that form the operational
mode sequence.
In the sequences that follow, the diagrams show the top clamp plate, the
snugger plate, Z clamp, mid plate, the board, the transport belt and the board
support. The top clamp is capable of two independent actions: in/out movement
and up/down movement (in tandem with the internal mid plate). The snugger
plate is part of the complete assembly that includes the mid plate and clamps.
Figure 1-3 Key to Operational Mode Sequence Diagrams
Snug Mode The Snug mode operational sequence is as follows:
1. The starting state of the APC module:
a. Top clamps are extended.
b. Mid plates are up.
c. Snug off
d. Z clamps off.
