According to Millsom Materials Handling , following the production and completion of different wooden parts and the packing of individual parts in a cardboard box, moving the cardboard box to the commissioning position and to place it on a pallet with other goods is difficult.
Since the cardboard box is generally large and its contents are heavy, the users have two options. The users can either employ at least two people to handle the box or purchase some type of device to do the job. The device must be capable of handling and palletising boxes with dimensions between 1500 x 300 x 200mm and 2900 x 300 x 300mm with weights between 20kg and 80kg, and should need one person to operate it. Millsom Materials Handling observe that the device should be easy to use, flexible and easily installed. The device must also be able to cover a large working area.
Schmalz, represented by Millsom Materials Handling in Australia and New Zealand, supplied devices that can handle cardboard boxes to one of the companies. The company’s cardboard boxes with heavy contents were sometimes deformed. The cardboard boxes were also not rigid, which made them difficult to grip and move. Schmalz were able to provide a solution for this combined material-flow and handling task and they were able to build it completely with components from their standard modular system for vacuum handling systems.
The device consisted of a vacuum tube lifter, JumboErgo 85, for a maximum load of 85kg, a double gripper with suction pads, which can be adjusted longitudinally, a blower to generate the vacuum and a slewing column crane, SKJ 110, capable of lifting loads of up to 110kg.
The SKJ 110 slewing column crane can either be screwed to the floor or mounted on a base plate (which permits mobile use) and carries the vacuum tube lifter, JumboErgo. With its 4m jib and a slewing angle of 270°, the SKJ 110 slewing column crane can move loads over a large working area. The double gripper of the JumboErgo 85 vacuum tube lifter is capable of lifting cardboard boxes of all shapes and sizes from the packing table, transporting them safely and positioning them precisely on the waiting pallet. The vacuum for gripping the boxes is provided by the blower, which means that the entire system needs only a mains voltage of 400V and no other connections are necessary.
The operator of the vacuum handling device was satisfied with this simple and economical solution. Two persons were normally needed in the past for the manual commissioning and palletising work, and their work was strenuous and presented a health hazard. One person can now do the work with the aid of the vacuum handling device. The handling device helped to result in less damage to the goods to be transported and the task of placing boxes on top of a stack on the pallet is made easy.
