The IMP.A.C. ROBOTEX 526 APR is an innovative fully automatic machine, complete with roller conveyors for moving empty and full pallets. This palletizer has been studied and designed to solve problems common to many users and precisely: 1. possibility of palletizing all types of tanks with different sizes and weights from 5 to 65 liters, using the same equipment. 2. Possibility of palletising and wrapping the pallet at the same time giving stability to the load and therefore the possibility of palletising unstable and slippery bags. 3. Possibility of installing this Palletizer in limited spaces as the overall dimensions are very small. It is a machine suitable for being inserted at the end of the line of fully automatic production plants where the presence of the operator is not required, for a maximum production of 450 tanks / h. The movement system is based on Cartesian axes and the positioning is controlled by an encoder. All the synchronisms of the movements are coordinated by a programmable modular system (PLC). The machine can be programmed to palletize bags of different sizes, formations and number of layers.
