Flexibility that inspires - the "roboSTACK" from IEF-Werner is your new partner for adaptable production. This palletiser combines state-of-the-art robot technology with the ability to convert trays of any size in the shortest possible time. Whether small or large batch sizes, changing projects or new requirements - the "roboSTACK" is the answer to your production needs. Experience flexibility that makes your business more efficient and future-proof.

  • General details

    Based on the proven varioSTACK palletiser, IEF-Werner has developed a new, very flexible palletising system. The result: the roboSTACK Flex with maximum flexibility from product handling to tray handling.
    The flexibility starts with product handling. The 6-axis robot allows workpieces to be positioned and orientated freely. This means that the palletiser can be easily adapted to any existing production structure.

    The "Flex" extension stands for "consistently flexible". With this additional option, a wide variety of tray sizes can be processed. The entire handling section of the trays can be infinitely adjusted wider or narrower. From small trays in the 1/16 euro size to large trays in the 1/4 euro size. It is worth noting that the changeover takes just a few minutes!

    The roboSTACK Flex shows its strengths when it is necessary to retool different products and/or different trays. It is predestined for the alternating production of small batch sizes. It is equally suitable for use when new projects need to be realised several times with short run times. Changeover to a completely new, as yet unknown follow-up project is also no problem.

    The robot, including the controller, is placed directly on the frame and fitted with a compact housing. This saves valuable production space compared to an external robot.

    Expansion stage roboSTACK Flex

    Motion simulation of the roboSTACK robot palletiser in the Flex version with adjustable feed belts, electric lifting fork and electric table cover.

    The electric lifting fork can pick up different tray sizes with an increased closing force. At the same time, the chute cover can also be electrified so that the palletiser can operate completely without compressed air.
