![]() ![]() Some require an air-amplifier to blow small products off the belt, but heavier applications require a linear or radial actuator. A reject belt that provides a method of removing an out-of-tolerance package from the conveyor line.This may limit line speed and throughput. Some older machines may pause the weigh bed belt before taking the weight measurement. This is typically mounted on a weight transducer which can typically be a strain-gauge load cell or a servo-balance (also known as a force-balance), or sometimes known as a split-beam. It sometimes has special belts or chains to position the product for weighing. ![]() The infeed is also sometimes used as an indexer, which sets the gap between products to an optimal distance for weighing. An infeed belt that may change the speed of the package and to bring it up or down to a speed required for weighing.Typically, there are three belts or chain beds: In filler applications, they are known as check scales. These checkweighers are known also as belt weighers, in-motion scales, conveyor scales, dynamic scales, and in-line scales. An automatic checkweigher incorporates a series of conveyor belts. ![]()
