Checkweighers quickly and accurately measure the weight and corresponding packaging requirements of any product as it is moving across the belt in the production line. Items are classified by preset weight zones which are sorted or rejected based on the predetermined classifications. These systems ensure quality control and customer satisfaction by verifying that products meet the target weight while providing cost savings through minimizing giveaway.

Checkweighers provide compliance to government regulations and assist with product tracking. Data captured consists of production counts, batch tracking, total weights, good weights and rejected weights. A diverse range of industries incorporate checkweigh systems into the production process, which include food, pharmaceuticals, cosmetics, beverages, transportation, chemicals, automotive and metal manufacturing and fabrication.

Smaller Scale

Smaller scale drag chain style checkweighers are ideal for can, jar, small carton (coffee), canned food, pet food, nutraceutical, paint, adhesives, produce, candies, box, tub, carton and other rigid containers. The drag chain style checkweigher is equipped with two strands of flat-link chain to carry your rigid package across a fixed scale section. The standard conveyor length is 36”; weigh table lengths range from 3” to 14” long; and conveyor widths from 1” to 10”. Conveyor speeds are up to 400 fpm with performance rates as high as 350 packages per minute and accuracies as high as +/-0.5g for capacities up to 10 lbs.

Small belt conveyors are used extensively with rigid, semi-rigid and flexible packages for products such as produce, meat, poultry, ice cream, FFS bagged sauces, flow-wrapped baked goods, coffee, tea, small cartons and spices. Small belt conveyor lengths are available in 12”, 14”, 18”, 20”, 24” and 28” and belt widths from 4” to 18”. Conveyor speeds are up to 300 fpm with performance rates as high as 220 packages per minute and accuracies as high as +/-0.5g @ 2 Sigma with capacities up to 20 lbs.

Heavy Duty

Heavy duty checkweigh systems are standard for concrete, cement, salt, sand and earth products. Conveyor speeds are variable up to 250 fpm with performance rates up to 50 packages per minute and accuracies of up to +/-0.05 lbs. @ 2 Sigma for capacities up to 110 lbs. and repeatability as great as +/-0.03 lb. @ 2 Sigma.
