The issue:
creating a depalletising system for composite cans incorporating a high-speed palletising system for trays and trays with bundles. A complete end-of-line solution was also required, composed of: shrink wrapping machine, labelling machine and pallet stacking system.
For the depalletising system, the customer requested the ability to load the pallets of composite cans at ground level, and unload the stacks of empty pallets, the layer pads and top frames in the same area in order to facilitate the work of the forklift operators. The speed requested was around 900 cans/min.
As regards the palletisation, the main issue was the speed required: 100 cpm and 9 layers/min. Additionally, the instability of the product was another challenge to overcome.
The system developed by Clevertech:
an automatic depalletiser for composite cans, Model RAD 2 EC A I1 PV 01 TORPEDO, was used for the depalletising system. The main, innovative characteristic of the Torpedo system is that the palletisation is performed by a robotic pick-and-place system, which allows all the problems of traditional pushing devices to be avoided.
The use of a second, auxiliary robot for management of the layer pads, top frames and empty pallets allows them to be stacked for return to the composite can manufacturers.
The TORPEDO system allowed the customer’s requirements for high efficiency standards and improved logistics management to be met.
For the palletising system, Clevertech proposed a high-speed AC 620 M2 SS1 ROCKET model palletiser.
This is a very high speed palletiser with robotic preforming area, composed of two independent robots. The layer is transferred directly to the unloading area with dedicated lifting plate in order to satisfy the production speed required, 9 layers/min. In addition, the system is completely integrated with a pallet wrapping, labelling and stacking system, in accordance with Clevertech's integration philosophy.
Performance data: Depalletiser: 900 cpm, 5 layers/min. 20 pallets/hour. Efficiency: over 99%.
Palletiser: 100 cpm, 9 layers/min. 8 pallets/hour. Efficiency: 99%.
