Case Packer for Spouted Stand-Up Pouches - Complete Line

Calmus Machinery just built a from-unscrambling-to-palletizing complete case packing line for spouted stand-up pouches (doypacks), tailored for a large baby food manufacturer abroad. The packing line consists of two pouch unscramblers, a wrap-around case packer with two pouch collators, a palletizer, and connecting conveyors. The case packing speed is 15 cartons per minute, with each carton holding 10 or 12 pouches in a single row. It receives disordered pouches from upstream, unscrambles them into two separate piles with consistent face-up and head orientation, collates and packs the pouches into cartons, and finally palletizes the cartons.

Pouch Unscrambler

This automatic pouch unscrambler is designed for organizing disordered spouted stand-up pouches to meet the feeding requirements of the collator for doypack case packing. It collects spouted pouches from the upstream packaging line, arranges them into a single file, spaces out consecutive pouches, orients all pouch heads consistently with the help of a vision system, turns them face-up, and flattens the pouches. This flattening step prevents folded pouches from causing jams during case packing.

Wrap-Around Case Packer

This wrap-around case packer is a form-load-seal 3-in-1 monoblock cartoning machine, which integrates case forming, pouch loading, and case sealing into a single compact and efficient unit. It picks one-piece pre-creased cardboards from the magazine, folds them into a U-shape, and conveys the folded blanks to the pouch loading station. The case packer is combined with two pouch collators. The collators collect pouches into two separate rows, push them alternately into the central indexing station, where a pick-and-place unit picks the pouches by their spouts and loads them into the formed cartons. Finally, the loaded cartons are conveyed to the next stations to be closed at the top and sealed at the minor flaps with hot melt adhesive.

Palletizer

We originally planned to use our rotating joint palletizer BJP32 for this project, but we found that the cobot palletizer CP30 offers greater flexibility for different palletizing patterns, so we switched to the CP30.

Although the maximum payload of the CP30 is only 30 kg, it is sufficient for this stand-up pouch case packing project, as each box weighs less than 3 kg. The overall efficiency meets the target speed. More importantly, the cobot palletizer can handle all palletizing patterns with just one gripper.
