This unit was developed to provide an alternative case packing of 4 liter milk bags into corrugated cases vs plastic dairy cases. The 4 liter milk filled bags are transported from the filling line by conveyor in single file orientation. The bags are diverted into 3 chambers of the case load station zone as they travel down the caser infeed roller chute. A corrugated dairy case is positioned under the load station for loading. A set of trap doors on the bottom of the load station opens to simultaneously drop all 3 bags into the case. These trap doors also act as case flap guides as they open up. The full case then exits and is push transferred 90 degrees for infeed to a case top closer unit.
