4. Poor pan installation. Crooked or loose pans, or pans banging against other objects, can create additional operating stresses, leading to prema- ture bearing or motor failures. A solid installation can be achieved in several ways. Quick-release pan-mount brack- ets such as those offered by MPI offer a solution. These brackets lock down
the pan securely while also enabling quick and flexible changes in pan placement. Another tip: Crossbars to which the pans mount should not exceed the manufacturer’s maximum recommended length. Be sure to follow the stated length recommendations.
Advantages of
Electric Shaker Conveyors
Properly installed and maintained
electric shaker systems eliminate the common causes of operating failures noted above while providing years of trouble-free service. In addition, they also deliver significant performance and cost advantages over their pneu- matically driven counterparts. Advan- tages include the following:
1. Efficiency. Electric shaker con- veyors eliminate disruptions caused by maintenance and repairs frequently required by pneumatic shaker systems, thus providing immediate and signifi- cant boosts in shop-floor efficiency. Also eliminated: wasteful leaks in air tubing, which can run thousands of feet, along with the need for air compressors, thus freeing valuable floor space.
2. Reliability. Given the harsh oper- ating conditions encountered in metal stamping plants, electric shaker con- veyors are designed, engineered and built to be extremely reliable. Some systems, including MPI’s M-series models, for example, avoid using seals and damping components that require maintenance and repairs. More-com- plicated pneumatic models feature more parts and assemblies that can break down. Except for the need to clear infrequent jams, electric shaker systems can provide years of trouble- free service.
3. Simplicity. Pneumatic systems require compressed air from compres- sors, often located far from stamping presses. The compressors, tubing and connections required with these shak- ing systems constitute a complicated infrastructure that requires lubrication, plus periodic and as-needed mainte- nance and repair. Electric shaker sys- tems operate virtually maintenance- free with much longer service intervals and fewer required spare parts.
4. Energy savings. Electric shaker systems use 71 percent less energy as compared with 3.4-ft.3/min. pneumatic setups. Given the number of stamping presses in a plant and how long they run—assuming similar run times for their scrap handling systems—annual energy-cost savings from electric shak- er conveyors can total tens of thousands of dollars.
