ABSTRACT:
An air conveyer receives an uppermost container group elevated by a lift device and transporting the container group horizontally. A pushing device is provided for pushing the uppermost container group onto the adjacent airflow conveyer by contacting the container group at one side thereof and moving horizontally toward the other side. A forward-fall preventive device is provided to be switchable between a closed state for lying forwardly in a pushing direction of the container group, as the pushing device moves horizontally, to be capable of preventing a forward fall of containers, and an open state for opening a forward position in the pushing direction of the container group when the container group rides the airflow conveyer to enable a discharge of the container group. A speed varying mechanism is provided for varying a relative speed between a transport speed of the airflow conveyer and a pushing speed of the pushing device.
