US Patent:

8578878, Nov 12, 2013

Filed:

Apr 23, 2007

Appl. No.:

12/297677

Inventors:

James M. Khoury - Strongsville OH, US
Charles Nagy - North Ridgeville OH, US
Stephen G. Nemethy - Lakewood OH, US
Mark J. Ignatius - Lakewood OH, US

Assignee:

Nordson Corporation - Westlake OH

International Classification:

B05C 11/10

US Classification:

118668, 118692, 118712, 118665, 118681

Abstract:

A can coating machine control system includes a coating control signal that functions as a go/no-go signal based on a plurality of monitored conditions such as can in position, vacuum pressure, gun in position, guard in position and speed condition. Local pressure regulation of the coating material in the spray gun is provided along with optional control of the material temperature. Local pressure regulation allows for optional spray weight control based on a wrap number derived from speed and gun spray-durations. A CAN to CAN network buffer is provided as well for primary network isolation. A gun control circuit may be used to select specific gun drive signals and to adjust gun drive signals based on real-time feedback of the actual spray duration.

Assignee:

Nordson Corporation - Amherst OH

International Classification:

F25B 1300
G10M 1900
G05D 2300

US Classification:

364186

Abstract:

A method of checking to determine (a) whether the heating elements and temperature sensors of the various components of a hot melt heating and dipensing system, such as, hot melt dispensers, hoses, and associated reservoir and manifold, are connected in proper circuit configuration, (b) whether any of the heating circuits are in an open-circuit condition and/or their respectively associated signal-controlled switches which control energization of the heaters thereof are short circuited, and (c) whether any of the temperature sensors are open-circuited. The checking is performed by a microprocessor having multiple channels to different ones of which are connected the sensors and signal-controlled switches of the different system components.
