tna ropac 5 ultrahigh-speed case packer for flexible bags

The tna ropac 5 is an ultrahigh-speed case packer for flexible bags that is capable of speeds of up to 300 bags/min. Part of tna’s performance 5.0 packaging system, the product uses semi-rotary bag stacking technology to quickly and efficiently pack small to medium-sized pillow-style snack bags into secondary containers.

Using continuously revolving horizontal platforms that can accommodate multiple rows of bags, the system is able to quickly and efficiently form, lower and side-load vertical stacks of bags into a secondary container such as a box. The stacking system avoids bags being gripped and dropped by vacuum heads, minimising the risk of product breakage and missed bags.

The product features semiautomatic, tool-less changeovers that take less than 10 min to complete, offering manufacturers flexibility over bag and case size. The case packer features a low number of moving parts, ensuring that there is less wear and tear of the equipment’s components. The unit also requires minimal power and air due to the low amount of pneumatic actuators and the semi-rotary action that avoids reciprocating motion.

The compact side-loading case packer can be seamlessly integrated with any upstream and downstream equipment, including checkweighers, case erectors and top sealers. With a width of 1220 mm, it was built to work with a VFFS system, enabling manufacturers to place a case packer after every single bagger. It even allows for the installation of two case packers in twin configuration. The product only measures 2120 mm in height, opening up the possibility to add a case erector on a mezzanine floor level above the case packer.
