n Lubrication Systems A Nordson dispensing gun, special timer, controller and low-flow rate nozzles comprise the can lubrication system. A patented gun incorporates an advanced design, eliminating dynamic seals to reduce wear. The gun operates at speeds up to 3,000 cycles per minute. Nordson nozzles provide fine atomization for even material distribution and a uniform spray pattern. n Ink-Dot Identification System n Inside Spray System Immediately identifies malfunctioning spray machines for reduced rejects and downtime, and significant labor and/or material savings. Applies a small dot of ink to the bottom of each can as it enters the spray machine. A different ink color is used for each spray machine, so if a problem occurs, the machine at fault can be fixed while all other machines continue running. Nordson inside spray systems provide fast, accurate application of waterborne or solventbased can lacquers. The systems are designed for consistent, repeatable material application at demanding line speeds. All inside spray systems include patented Nordson dispensing guns, pumps, fluid heaters, filters and nozzles, configured to best meet application requirements. The system easily applies colored and ultraviolet inks and can be configured to apply thermal sensitive inks to the outside of food cans. n Spray Pressure Control System n UV Curing System for Rim Coat An innovative UV lamp design cures can rims simply, quickly and efficiently. Nordson UV systems convert nearly 93 percent of the energy consumed into usable power, making the rim coat curing system 25 percent more efficient than competitive technologies. The system can be retrofit into existing lines for single-file applications or configured for mass conveyor applications. Maintains consistent inside spray coating weights for enhanced product quality and operating efficiency. The system provides hydraulic pressure control for every spray gun on the line, eliminating fluctuations caused by the pump and the operation of other guns. Coating weights can be accurately controlled to minimize variation. Lower spray pressures can be used for cleaner, more efficient operation. The increased efficiency results in significant coating material savings, lower VOC emissions and reduced clean-up and maintenance costs. n Temperature Control Unit Effectively monitors and maintains material temperature by heating or cooling during can coating operations. The TCU heats, cools and circulates the closed-loop conditioning water through heat exchangers and ancillary components to ensure proper temperature of the coating material throughout production. Cleans container-coating nozzles automatically, without stopping production. The system sprays a 300 psi, short-duration stream of water directly on the nozzle, washing away excess coating material between lacquer sprays. Nozzles stay free from coating build-up, so dried coating cannot detach from the nozzle and be deposited into the cans. Manual nozzle cleaning is reduced to once per shift, minimizing labor requirements and keeping the production line running cleaner, longer. Spray Monitor System Automatically monitors important operating parameters inside the spray gun. These include base pressure, spray pressure, actual timer duration, spray count, spray rate, gun open and close time, and actual gun spray time for each and every can. Products outside predetermined parameters are detected immediately at the spray machine, reducing scrap, improving quality and speeding productivity Apply a defined and controllable bead of wax or mineral oil lubricant to the open end of cans, assuring the precise amount of lubricant is on each can as it enters the necker. The systems provide accurate, adjustable control with varying line speeds up to 3,000 cans per minute, and automatically maintain the size and placement of the bead.
