Many combination weighers can operate in a mode that allows the counting of pieces for those applications where the package is sold by count rather than weight. But traditional combination weighers have problems with speed, accuracy and efficiency when running low piece counts. Those systems must skip an entire packaging cycle to discharge the over-filled buckets down towards the packaging machine in order to reject it between the scale and bagger. This slows the packaging system, resulting in lower operating efficiencies.
Yamato’s patented Reject/Recirculation System solves that problem by rejecting over-counts at the weigh bucket without skipping a packaging cycle. The result? Faster speeds, better count accuracies, and higher efficiency.
The Reject/Recirculation system also includes an optional recirculation conveyor at the weigh bucket level to provide easy and immediate recirculation of product back into the infeed stream. And, it provides gentle handling of rejected product so the product is completely reusable.
Because the Reject/Recirculation System rejects at the weight bucket without affecting the weigher cycle, we can also solve counting applications that have target counts down to one piece. And, the system also allows us to increase count accuracy to virtually 100%.
The patented Yamato Reject/Recirculation System is available for all industries with both dry and washdown environments and can be used on a wide range of Yamato weighers for all applications.
