Vibratory feeders are self-contained systems each consisting of a bowl feeder that orients the parts and a vibrating drive unit, upon which the bowl feeder is mounted. The drive unit, equipped with a variable-amplitude controller, vibrates the bowl feeder, forcing the parts to move up a circular, inclined track. The track is designed to sort and orient the parts in consistent, repeatable positions, according to certain requirements. The bed length, width and depth of the vibratory feeder can be adjusted, and special bed liners can be installed if the material to be handled is abrasive. Dust-proof outlet covers can be attached to the inlet and discharge to reduce dusty material residue or a completely enclosed tube feeder can be specified. Vibratory feeder manufacturers can use stainless steel to meet sanitary requirements in food processing.
Vibratory feeder manufacturers equip their products with a variety of controls depending on type. Pneumatic feeder controls include a quick-acting valve, an air line filter, a pressure regulator gauge, a lubricator and a long air hose. A transformer-type device, available for electromagnetic vibratory feeders, adjusts the intensity of vibration by varying the applied voltage. Electromechanical feeders have a wall-mounted control box with an on/off button or switch and overload protection. Special controls for remote operation include two speed, maximum-to-minimum material flow controls for batch weighing and panel board controls for multiple feeder installation. An accelerometer can be attached to the drive unit to monitor the amplitude and to apply a correction to the feeder, which tends to vibrate more quickly as the material level drops.
Vibratory feeder manufacturers serve the pharmaceutical, automotive, chemical and mining industries. Other industries utilizing vibratory feeders include steel, glass, foundry, concrete, recycling, bakery, railroad unloading and plastics. Chemical plants typically use vibratory feeders to control the flow of ingredients to the mixing tanks. Foundries use vibratory feeders to add binders and carbons to sand reprocessing systems. The pulp and paper industry uses vibratory feeders for chemical additive feeding in the bleaching process, while the metal working industry uses vibratory feeders for feeding metal parts to heat treating furnaces. Vibratory feeders are also used by water and sewage treatment plants in chemical additive handling. Other materials that are separated by vibratory feeders include powder, plastic pellets, dry chemicals, coal, metals, ore, minerals, aluminum, mining and aggregates, grains, seed, dry detergents, ceramics, textiles, rubber, fibers, wood chips, salt, sugar and many, many more.
Parts feeders provide a cost-effective alternative to manual labor, saving manufacturers valuable time and labor costs. One operator can oversee a number of automated machines, as opposed to one worker hand loading one machine. Hand selecting and inspecting is also time consuming and labor intensive. The tediousness of the process can subject the workers to repetitive motion injuries. Using vibratory feeders typically results in a better product as well. When selecting a parts feeder, several factors must be taken into account, including the industry, application, material properties and product volume. (Less)
