Packaging Machinery Technicians

Packaging machinery technicians have many duties including building machinery, installing and setting up equipment, training operators to use the equipment, maintaining equipment, troubleshooting, and repairing machinery. Many of the machines today are computer-controlled and may include robotic or vision-guided applications.

Machinery builders, also called assemblers, assist engineers in the development and modification of new and existing machinery designs. They build different types of packaging machinery by following engineering blueprints, wiring schematics, pneumatic diagrams, and plant layouts. Beginning with a machine frame that has been welded in another department, they assemble electrical circuitry, mechanical components, and fabricated items that they may have made themselves in the plant's machine shop. They may also be responsible for bolting on additional elements of the machine to the frame. After the machinery is assembled, they perform a test run to make sure it is performing according to specifications.

Field service technicians, also called field service representatives, are employed by packaging machinery manufacturers. They do most of their work at the plants where the packaging machinery is being used. In some companies, assemblers may serve as field service technicians; in others, the field service representative is a technician other than the assembler. In either case, they install new machinery at customers' plants and train in-plant machine operators and maintenance personnel on its operation and maintenance.

When a new machine is delivered, the field service technicians level it and anchor it to the plant floor. Then, following engineering drawings, wiring plans, and plant layouts, they install the system's electrical and electromechanical components. They also regulate the controls and setup for the size, thickness, and type of material to be processed and ensure the correct sequence of processing stages. After installation, the technicians test-run the machinery and make any necessary adjustments. Then they teach machine operators the proper operating and maintenance procedures for that piece of equipment. The entire installation process, which may take a week, is carefully documented. Field service representatives may also help the plant's in-house mechanics troubleshoot equipment already in operation, including modifying equipment for greater efficiency and safety.

Automated packaging machine mechanics, also called maintenance technicians, perform scheduled preventive maintenance as well as diagnose machinery problems and make repairs. Preventive maintenance is done on a regular basis following the manufacturer's guidelines in the service manual. During routine maintenance, technicians change filters in vacuum pumps, grease fittings, change oil in gearboxes, and replace worn bushings, chains, and belts. When machines do break down, maintenance technicians must work quickly to fix them so that production can resume as soon as possible. The technician might be responsible for all the machinery in the plant, one or more packaging lines, or a single machine. In a small plant, a single technician may be responsible for all the duties required to keep a packaging line running, while in a large plant a team of technicians may divide the duties.
