OVERVIEW
Chapter Issue 3 Aug 14 Over the Top Snuggers (OTS) Manual 1.3
Each OTS rail consists of:
• Board Support and Snug Plate (fixed on the front rail)
• Mid Plate housed in the Machined Body it has a pneumatic manifold
located at the rear of the assembly.
• Over the Top Clamp, comprising; the Swivel Plate the Bearing Support
Plate and the Top Clamp Plate
• A Pneumatic Manifold
• Magnetic Tooling Pins
Board Support and
Snug Plates
The board support, supports the product while it is in the tooling area of the
machine. The snug plate moves in and out to snug the product; this movement
is provided by the snugger actuators and guides in the mid plate assembly. If a
product is a shape that does not have parallel sides the snug plate pivots to
accommodate it. On the front rail this plate is fixed and does not move in the Y
axis.
Mid Plate Sixteen brakes hold the mid plate in place during printing; they brake against
the flanges and the side wall of the machined body. Print pressure up to 20Kg
in can take place. To release the brakes, a vacuum ejector valve switches on;
this pulls the brakes away.
Over the Top Clamp This assembly comprises three plates: Swivel, Bearing Support and Top Clamp.
The swivel plate is mounted on the bearing support plate which has a central
bearing and linear guides at both sides. If a product is a shape which does not
have parallel sides, the clamps can pivot to accommodate the shape and align
with the snugger. On the rear clamp only, the top clamp plate slides over the
top of the product to give top clamping.
Modes of operation can be programmed via the software. The parameter, OTS
Retain Mode, if enabled, allows the board to be held during the unclamping
phase of the cycle (see Sequences later in this manual.) If disabled, the clamp
is retracted preventing the possibility of smudging the print.
A forward/back cylinder mounted in the centre front of the block is used to move
the over top clamp forward or backward. The combination of up or down and
forward and backward movements allows the over the top clamp to be moved.
This either clamps the product, or it comes to rest at the same height as the
product, where it is positioned behind the snug plate at the rear of the assembly.
Manifold The manifold delivers pneumatic air pressure through ‘O’ ring sealed ports to
the various actuators which drive the OTS movements.
