INDUSTRIAL CONTROL SYSTEMS
SPECIALTY CORE BATCH MIXING
Our engineering group provided the controls expertise necessary to automate a batching process for bowling ball cores at Ebonite International in Hopkinsville Kentucky. This was a Class I Division 1 location requiring explosion proof design considerations. Batching operation utilized the infeed control of (4) different powders and (3) different liquids in varying ratios and quantities. The batch quality criteria is judged on density with allowances of only 0.2%. Therefor accurate weigh-ins was an absolute must. The batch control system needed to be easy to use and very versatile since the core recipes changed on a shift-by-shift basis. Matrix engineers also performed intensive start-up, check out, and operator training.
Matrix Engineering provided electrical engineering necessary to design, specify as well as build and install a control system for an electro-static painting process. This system consisted of an Allen Bradley SLC 500, 7 slot rack, linear positioner, and AC & DC variable speed drives. The variable speed drives controlled the speed of the main overhead conveyor throughout the plant. We design the system so that the operators could easily change the paint system using the linear positioner to accommodate varying cylinder sizes. Matrix Engineering also performed intensive start-up and checkout, and operator training.
MONOCAL BLENDING & PACKAGING CONTROL
Matrix provided the electrical engineering necessary for designing integrating a control system into an existing blending and packaging system for a new product. To accomplish this we used an AB SLC 500 and a Panelview 1400 operator interface. We assumed control of an existing blending and pneumatic conveying system as well as a very complex dust collection arrangement. Essentially a new product was being produced and packaged with an existing system, however this same system needed the ability to blend and convey the old product while producing the new product without cross-contamination concerns. This resulted in a complex control scheme. We also tied this system in with their existing DCS system for monitoring and control purposes. Matrix provided the engineering for a new control system for the blending, conveying, packaging & dust control system. Matrix also provided total commissioning/start-up support for this system.
Provided electrical engineering necessary to specify as well as build and install Allen Bradley PLC’s to replace existing control systems on several production machines for manufacturing refrigerant cylinders. These machines included two pressure testers, two spud welders, hole punch, a convolute punch, and a valve crimper.
GIRTH WELDER SYSTEM
Matrix Engineering provided the controls expertise necessary to design a controller for Amtrol's cylinder girth welders. That system consisted of an AB PLC with Panelview operator interface and a servo-motor to control the speed of the rotating cylinder while being welded. The control system was programmed to accommodate many different cylinder diameters while maintaining a proper weld speed as well as determining the exact length for one cylinder revolution.
BOWLING BALL BALANCE SYSTEM CONTROLS
Matrix Engineering provided the low cost control system to locate and mark the “top weight” in a bowling ball which cannot be seen on the surface of the ball. This top weight directly affects the performance of the bowling ball and must be precisely located and marked so it may be drilled for use. The control system utilized a PLC, servo motor and drive, strain gauge, and a touch-screen operator interface. In addition to locating and marking the top weight, the control system produced the actual weight of the “top weight” in ounces as well as the total weight of the ball. The total system cycle time was kept between 20 and 30 seconds which was a key factor in production.
