Robot Pallet Indexing

“S.A.M.” Quality You Can Count On

The “S.A.M.” equipment is designed and built to be used in a Class I, Group A through D; or Class II, Group E environment.

The machine is enclosed and insulated not only to protect the operators, but also to make the machine energy efficient.

The SAM robot pallet indexing spray machine is designed for spraying a multitude of parts positioned on a single flat pallet. The pallet is manually loaded and automatically transferred from station to station within the confines of the machine. The pallet is transferred from a pre-heat zone into an enclosed robot spray booth. Once the items are sprayed, the pallet is transferred into a cure and cooling zone. Upon curing and cooling, the pallet is escaped to the operator unload station.

The pallets are designed to facilitate quick changeover by simply replacing the part masks. This quick change tooling coupled with RsView interface minimizes downtime for part changeover.

Custom made part masks can be designed and manufactured to accommodate most any customer’s needs or requirements.

The part mask can be designed to either hold an individual single part or if the part configuration allows, multiple parts. This method of arranging similar shaped parts will also increase production output.

Touch Screen Control

Allen Bradley RsView – Operator interface – (touch screen)

The RsView is mounted at the rear of the machine in close proximity to the spray booth. This facilitates spray set-up in the spray booth.

The RsView touch screen controls all aspects of the machine by simply entering a part number or a “recipe.” The machine will automatically adjust to the requirements of a particular application.

The RsView controls the temperature of the pre-heat tunnel, cure tunnel, index and dwell times of the pallet, gun settings, etc.

Recipe Programmable

The RsView interface is capable of storing a multitude of recipes. Each recipe is specific to the part that is to be processed.

By simply entering the pre-programmed, stored recipe, the change over and production requirements are quick and simple to accomplish and maintain.

Pneumatic Transfer

The pallets are automatically transferred by pneumatic actuated components.

Once the pallet is placed at the load station, all operational sequences are automatic throughout the entire machine.

The pallet transfer is designed to provide a smooth transition from one station to the next.

Please note: as an option, the pneumatic transfer can be replaced with electrically actuated components. This option should only be considered if the application material process contains “NO” explosive or ignitable compounds.

Stainless Steel Booth

The spray booth at the rear of the machine is constructed from 304 stainless steel, fully welded to form an enclosure that can withstand the demanding requirements of solvent based sprays as well as water based sprays.

The spray booth also incorporates air impingers (diverters) that turn the air several times to eliminate heavy particulates prior to entering the filter media. Directly behind the impingers is the filter media. The filter area is approximately 720 sq. In.

This surface area can be increased if a pleated style filter is used.

Spray Booth Doors

The spray booth area is only accessible through the heavily constructed dual doors. The booth doors have tempered glass for viewing the spray cycle. The doors have a cam style door lock mechanism that secures both of the doors in the closed position.

Access to the spray booth is only attainable after the machine purges itself and the “VOC” laten air reaches safe levels; only then will it allow entry into the enclosed spray booth.

Electrical safety switches are also utilized should the pneumatic safety locks be overridden and the doors opened.

Activation of the electrical safety interlocks will cause the machine to immediately shut down.

Capture System 2000 CFM

Our patented air capture system provides a means to capture and contain VOC’s generated in the spraying and flashing off of materials being applied.

Through ductwork, dampers, filters, and blowers, the collecting and discharging of VOC’s is efficiently accomplished.

The VOC’s are in turn delivered to an oxidizer unit that destroys them to comply with EPA regulations.

The capture system is of a “Cascade” design. This simply means that the “VOC’s” generated through out the process is gathered from the least of the generated “VOC’s” to and through the more concentrated levels.

The capture system finally evacuates the “VOC”s” through duct work, filters and blowers to an oxidizer.

A magnehelic gage, transmitter, and a photohelic pressure switch/gage monitor the airflow through the filters and the discharge airflow to the thermal oxidizer.

These instruments have set points established to warn the operator of problems such as poor airflow and/or filter flow. The instrumentation is interfaced to the Allen Bradley PLC.

When the air flow drops below a certain set point and the problem is not addressed, the machine will automatically shut down. This instrumentation can also be provided to initiate visual warning lights and/or audible alarms.

Fanuc Paint Robot

To provide consistent repeatability, a Fanuc (6) axis robot is utilized.

Once the spray pattern is determined and stored, it is directly tied to the main “recipe” and accessed from the Allen-Bradley RsView touch screen.

The Robot is a Fanuc 6-Axis Robot with an air purge bag**for use in hazardous environments with an RJ3 controller.

** The purge bag has been replaced with a self-purged style robot.

Safety is Key

Several safeguards are an integral part of any of the SAM equipment.

Directly in front of the operator load/unload station is an “E” stop pull cable that is accessible from three (3) sides.

Safety interlocks at the rear in the spray booth provide an efficient means of ensuring that the spray booth remains closed during operation. This safety interlock is pneumatically actuated and remains engaged for a period of time while the machine purges to safe levels.

Electrical switches are also mounted at the rear on the spray booth doors. Should the door interlocks be manually overridden, activation of the switches by opening the doors will immediately shut the machine down.
