Uncrating the System

The Ultra–Flo Shot Metering Dispenser was carefully
packaged for shipment by Graco. When the system
arrives, perform the following procedure to uncrate the
system.

WARNING

EQUIPMENT MOVING HAZARD

Removing the unit off the pallet without following
the uncrating procedure could cause personal
injury and possible damage to the equipment.

To uncrate the system, do the following:

1. Inspect the crate carefully for shipping damage.
Contact the carrier promptly if damage is discov­ered.

2. Remove the sides and top of the crate.

3. Inspect the contents carefully. There should not be

any loose or damaged parts.

4. Compare the packing slip against all items in­cluded in the crate. Report any shortages or other
inspection problems immediately.

5. Remove the band straps that hold the Ultra–Flo to
the pallet.

NOTE: The Ultra–Flo is ready for installation. Before
installing the system, read the “Overview” section on
page 5 to become familiar with the system components.

Overview

Metering and application system

The complete Ultra–Flo Shot Metering Dispenser (SMD) is comprised of three components; shot meter and drive
unit (with pressure and over travel sensing), inlet valve with air solenoid, and junction box, all assembled together
as a single package. The SMD can be mounted on top of a stand or nearly anywhere else. It’s connected by hoses
to a pneumatically operated dispensing assembly (not included), which can be adapted to mount on almost any ro­bot arm. The remaining two dispensing and control components and corresponding installation and operation
instructions are provided by other manufactures.

A typical robotic metering assembly consists of an Ultra–Flo 50 cu. in. Shot Metering Dispenser, and automatic dis­pense valve. The materials are dispensed from the meter through an automatic dispense gun. The location of the
Ultra–Flo should be as close to the dispensing area as possible or mounted directly to the robot frame.

Metering assembly operation

A user supplied servo motor transmits power to the
ball screw. A push block is attached to one end of the
ball screw. The push block presses against the piston
moving it into the cylinder and forcing the sealant or
mastic out.

Refill System operation

When the lead screw reaches its pre–determined ex­tension and the material is expended from the cylinder,
the motor reverses which retracts the ball screw and
push block. A fill valve which is threaded into the cylin­der wall is opened and the sealant or mastic is forced
into the cylinder through an annular passage between
the outside of the displacement rod and the inside of
the cylinder. With the refill cycle complete, the fill valve
is closed, and the system is ready to resume dispens­ing. Two proximity switches act as safety backups for
both fill and dispensing to shut the system down in the
event of displacement rod overtravel. End of travel,
and end stroke marks are provided on the tie rods for
reference.

Junction Box Panel

The junction box panel includes the necessary ter­mination points for communication back to the control­ler.

Required Air Supply

The system requires a 1/8” NPT(m) air line to the
Ultra–Flo meter. The air supply should be filtered, and
capable of maintaining a minimum of 60 PSI under all
operating conditions.

Required Electrical Supply

The electrical controls for the system are provided by
the Robot Manufacturer’s Control System.

Over Pressure Protection

A 5000 psi rupture disc is provided for over pressure
protection.

Temperature Conditioning

This unit includes a water jacket that encloses the fluid
cylinder. For temperature conditioning, 1/2 NPT(F) inlet
and outlet ports are provided to connect to a condi­tioned water supply and return. Maximum water pres­sure of this jacket is 100 psi.

309280 5
