A new machine design for handling and collating small- to medium-sized pillow-style bags from one or several form-fill-sealers enables the combination weigher case packer to hit speeds of 300 bags per minute, which the packaging machine manufacturers says is the fastest system on the market. According to tna, the typical speed of existing case packers today for similar flexible packaging applications is about 120 bags per minute.
The combination weigher was introduced during interpack 2017 at a special off-site exhibit area large enough to accommodate the entire line (as well as other lines), which consists of a bag maker, a takeout conveyor, a case packer, a bag handler and collator, and case infeed and outfeed conveyors.
The servo-driven case packer’s innovation centers on continuous rotating shelves for weight checking machine that work independently from case loading to yield such high output. This patented semi-rotary bag stacking synchronizes seamlessly with the bag handling system, but these are two separate operations in the complete system.
