The
SCS Shuttle Car Distribution System provides the equipment and controls
to automatically deliver mixed sand batches from any batch or continuous
mixer to any core machine fed by the system.
The advantage to this system is reduced
maintenance and calibration since only one mixer is required to feed
multiple core machines.
The SCS is supplied as a complete system
including car, controls, track system, and festoon system.
Delivery Car
The
SCS car is a compact, easy access vehicle that travels on solid axle,
flanged wheels. The car
includes apolyethylene 60° hopper that allows the sand to slip out of
the car and into the core machine hopper. This replaceable hopper allows
minimal buildup and provides simple cleanup. A high frequency electric
vibrator aids in the removal of sand from the car, minimizing sand
buildup.
Included are safety rail bumpers on each end
of the car that will disable the system in the event that the car
encounters a person or object. A lighted beacon and warning buzzer are
mounted on the car to warn operators of impending motion.
Drive System
The
SCS car body travels on a set of four 8" diameter cast iron wheels. High
quality pillow block bearings support the 2" diameter axles for years of
trouble free service. The drive chain is #60 and is powered by a 1 HP
three phase motor. An in line brake is included as standard equipment
for safety reasons. Standard run rate is 100 feet/minute but this can be
increased on high speed systems
Door Assembly
The
SCS door assembly is built around the concept of rugged durability. The
door is driven by a high force linear actuator. The door is constructed
of ultra high molecular weight polyethylene and includes integral
wiping. The entire door hopper is lined with UHMWPE for reduced sand
sticking.
PLC Control System
This
system governs the operation of the SCS shuttle car and gives necessary
instructions to the mixing system being used. There are both manual and
automatic modes of operation for the mixer and SCS system, as well as
calibration and resin level selection.
The standard control system includes logic
for five core machines, one home position, and one cleanout position.
Additional logic can be added as an option.
Four batch recipes that can be assigned to
any of the core machines (zones) are standard. The mixer to be used with
the system must be capable of the quantity of resin levels to be used.
This allows for maximum flexibility of operation with the minimum of
complexity.
Included is a 3-button operator enclosure
for each core machine. These enclosures contain an emergency stop
switch, a lighted push button, and a HAND-OFF-AUTO switch. In OFF, the
core machine is de-activated from the system. In AUTO, the SCS will
deliver sand based on a level switch in the core machine hopper. In
HAND, the operator can manually call for a batch by pushing the lighted
push button.
On Board Controls
The SCS car has built in controls for the
primary function items located on the car body. Housed in this system
are the motor starters, door speed controllers, safety interlock
circuit, and minor logic circuitry. Location of these items in the car
greatly lessen the wiring requirements in the festoon cable system.
Track Festooning Cable
The SCS rail is ASCE 20-lb standard rail.
The rail is provided in sections that bolt together and attach to the
customer’s existing mezzanine or support device. Included are positive
stops for each end of the track that will activate the safety bumpers
and prevent the car from leaving the end of the track.
The festooning cable system that connects
the car to the PLC controls includes all support arms, festooning track,
and cable supports required for the specified length of the run.
Easy Access Panels
The sides of the car body are easily
removable to allow for cleaning and maintenance. The inside of the car
is roomy, allowing for quick and easy service. All primary operating
components are standard, off-the-shelf items that can be found at most
high quality industrial supply houses.
