Our range of checkweighers ensure consistent pack weight with a choice of reject mechanism for bags, cartons, boxes or sachets that fall out of the specified range / parameters. Bags of the wrong weight will be automatically rejected ensuring all the products supplied are of the correct weight.
All of our checkweighers use three belts (a chain belt system): The infeed belt is used to change the speed of the item in preparation for weighing, allowing a consistent space between products. This is followed by the load belt or weighing section which uses a torsion load cell to detect the weight of the item. The built-in computer takes many weight readings from the transducer over the time that the package is on the load belt to ensure an accurate weight reading.
The final belt is the reject belt where the item can be rejected by one of the various reject systems. An additional printer to print daily output report can also be added with this machine. Inline Checkweighers are sometimes referred to as conveyor checkweighers, belt weighers, in-motion scales, conveyor scales, in-line scales.
