The N-3300 and
N-4600 Series Foam Dispensers have the following
common features:
- Positive
displacement, single acting, fixed ratio lance
piston meters ensure on ratio proportioning
and accurate shot delivery. Meter capacities
are sized for production requirements.
- Power
flow valves for both the inlet and outlet
of each meter ensure that fluids are displaced
to the gun accurately and on ratio.
- Metering
Unit is hydraulically powered with electronically
adjustable constant flow rate technology.
This provides a powerful and robust drive
package that maintains material flow rates
even against variable loads. Time required
to dispense a shot is always repeatable.
- Closed
loop feedback control of metering unit provides
a very high degree of shot size consistency.
- Flush
sensing, high accuracy pressure transducers
are used to monitor and control material pressures
at all times to ensure a stable process.
- Common
dual circuit Hydraulic Power Unit provides
all the power for both the Metering Unit and
Impingement Mix Gun. This helps conserve floor
space and reduces equipment costs.
- Impingement
Mix Gun is hydraulically powered to minimize
weight and size as well as to maximize operating
power and reliability of gun.
- Impingement
Mix Gun includes:
--Hardened and precision lapped Tool Steel
mix head components for reliably good mix
and long service life with minimum maintenance.
--Choice of pistol grip or parallel handle
trigger designs for optimized ergonomic manual
applications.
--Heated gun maintains temperature during
idle periods, thus requires no test shots
when production resumes.
--Gun Open and Closed position sensors for
proper sequencing with dispenser controls.
--Quick disconnects on all cables for ease
of service.
- Entire
system is heated as required from supply source
to dispense tip and controlled using PID temperature
controllers for each heated zone. Primary
heated zone utilizes fluid heaters and probe
type sensors inserted into the fluid stream
for high heating capacity and precise temperature
control.
- Each
heated zone includes a redundant over-temperature
controller complete with its own separate
temperature sensor for safety backup.
- Heated
Hose Bundle connects the dispenser to the
gun and is available in lengths to suit the
application. Designed to minimize size and
weight of the assembly in order to maximize
flexibility and ergonomics, yet is built with
components rated for continuous flexing in
order to maximize reliability and minimize
maintenance required.
- One
Heated Hose Bundle and Gun per system is standard.
A Dual Gun (DG) option is available for manual
dispensing applications. This option provides
online hot backup capability.
- Nema
12 rated PLC Control Panel built to “generic
automotive” (JIC) standards controls
all dispenser functions. Allen-Bradley SLC
500 Series PLC is standard. Other PLC’s
and custom panel designs available upon request.
- Door
mounted 10 1/2” Quickpanel Color TFT
Touchscreen is provided for HMI / MMI functionality.
The Touchscreen is also utilized for password
protected access to adjustable parameters
such as Shot Setups, Sequence Setups, etc.
An optional Remote Operator Station (ROS)
is available. Other brands and types of touchscreens
available upon request.
- 16
programmable shot sizes are available as standard.
Additional programmable shot sizes available
upon request.
- 4
programmable 12 step sequences are available
as standard. More and / or longer programmable
sequences are available upon request.
The N-3300 and
N-4600 Series Foam Dispensers are available
with many other optional features and hardware
packages that facilitates their integration
into a foam dispensing cell. Features such as:
- Tool
Tip Cleaners for cleaning the gun dispense
tip.
- Hose
Management Systems for suspending and retrieving
the Heated Hose Bundles improves the ergonomics
of a manual application as well as extends
the life of the bundle through proper routing
and retrieving of hoses in a manual or automated
application. Also provides a safety feature
to stop the conveyor if the hose is entangled
with a moving body.
- Material
Supply Packages such as; totes, pumps, pressure
pots, etc., for supplying the materials to
the dispensers.
- Networking
/ interfacing the dispensers to other controllers
such as; robots, cell controllers, automatic
vehicle identification systems, process verification
systems, factory information systems, etc.,
through many types of interfaces and networks
such as; discrete I/O, Remote I/O, Data Highway
Plus, DeviceNet, ControlNet, Ethernet, etc..
