PART FEEDERS FOR AUTOMATED ASSEMBLY

Introduction to part feeder:Part feeders are machine that orient parts so that robust or other automated processes can capture and use or package of parts and components.Parts feeders are important for automating the production line and assembly system, and are used by an overwhelming majority of manufacturers in automated industries.Parts Feeders are excellent at high speed feeding and, due to a unique horizontal vibration system and isolated bottom, are vibration resistant. A parts feeder has three major functions: storing, aligning and feeding.

Part FeEDER SELECTION GUIDE

Part Feeder Work piece Method of operationAdvantage Disadvantage

Vibratory Bowl Small engineered partsElectro-magnet induced vibrationMostly used in automated assembly linePassive orienting system and feed one part at a timeRotary FeederSmall engineered parts Uses bowl that spins and force outside of bowlFaster and less noisy than vibratory feeder Pneumatic FeederIdeally suited to convey closures toCapping machine, also handling of many small partsThe piston function via hydrullics or pneumatics motor to force parts through tubeLow capital cost ,reliable and minimal maintenance requiredHigh power consumption than mechanical feeder

Part FeederWork piece Method of operationAdvantageDisadvantage Magnetic Feeder Can be used for parts made ferromagnetic materialsMagnetic force to lift the partsEnvironmentallybengins,prevent contamination ,reliable and minimal maintenanceThe magnets should have hoilding capacity of 10 to 20 times more than partsProgramable FeederCan be used for parts more than one family partCombines traditional with part feeding technology with programmable tool modulesLess down time due to changeover from one part to next orient most of the parts High cost and complicated planning logarithm can lead to poor realibility

Applications of part feeder:1). Metallic parts: parts feeders can align and feed anything from general nuts and bolts to specific industrial metal parts. For feeding springs which are easily tangled, the parts feeder is provided with a special unraveling mechanism.

2). Foodstuffs: parts feeders can convey various foodstuffs, such as candies and crackers, products in cartons such as ice cream or dry soups, or other packaged goods. The parts feeders can accomodate the wide ranges of size, shape and weight.

3). Rubber parts: Rubber parts are soft and thought to be difficult to feed due to rubber's large coefficient of friction, parts feeders can align and feed rubber parts using technologies we have developed such as matching the vibration characteristics with the rubber's characteristics and a special-processing of the bowl.

4).Medical equipment:parts feeders are important contributors to the clean environments required in the manufacture of medications in pill or tablet form, as well as for medical equipment, such as syringes
