摘要:
A method of operating a plurality of machines. Each of the machines uses a servo motor and a motor drive coupled to the servo motor, and the motor drive incorporates a regenerative braking system. The method comprises synchronising the servo motors in order to achieve overlap of the acceleration phases of some machines with the deceleration phases of other machines and providing electrical power from the regenerative braking systems of machines in a deceleration phase to machines in an acceleration phase. A controller for a machine implementing the method, and a system comprising such a controller and a plurality of machines are also disclosed.

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.

摘要:
An apparatus is disclosed for the application of a polymer resin to a threaded fastener, where the fastener includes a cylindrical body and the threads of the fastener are formed in a bore extending diametrically across the body. The apparatus generally comprises a conveyor, a resin application station and a fastener orientation station. The conveyor carries the fasteners along a predetermined path of travel, and includes one or more fastener support members that permit the individual fasteners to rotate about the axes of their cylindrical bodies. The application station comprises a nozzle which directs a stream of the resin toward the travel path of the fasteners. The orientation station includes a guide member which operates to rotate each of the fasteners relative to the conveyor as they move toward the application station, and to thereby properly orient the fasteners so the threaded bore of each fastener will intersect the resin stream as the conveyor carries the fasteners along the travel path and through the spray station.
摘要:
A method and apparatus for applying coatings to a portion of the internal bore or threads of a fastener or similar article having an opening on at least one end is provided. A 360° coating with material is provided using centrifugal force to assist in direction the material to a desired surface, which does not require use of a pressurized air stream in order to propell the coating material toward the walls of the article desired to be coated.

摘要:
A mechanism and process for coating tapped holes in specialty articles having varying external configurations, such as metal stampings. The specialty article is positioned in a preselected orientation at a loading station, and is then engaged by a carriage assembly and moved from the loading station to a heating station, and then to a spray and discharge station. During movement between stations, the article is maintained in the preselected orientation to allow proper heating and spraying of the tapped holes.
摘要:
An apparatus for providing a barrier coating on a portion of discrete objects such as fasteners utilizing a liquid coating material is provided. The present invention introduces either a plurality of loose or interconnected parts onto a magnetized conveyor system and optically senses when parts are present. When parts are sensed, the sensor triggers a discrete shot of liquid coating material such as a fluorocarbon to be deposited onto a predetermined portion of each part. These parts can then be transferred to a second magnetized conveyor system that supports an opposite surface of the parts than the first conveyor. The invention can also remove excess coating material and also be provided with dryers or heaters to fix the coating material to the parts if necessary.
