Mobile Manipulator for handling sacks from warehouse to production line
15 June 2021
A large Italian manufacturer of plastic components for industry needed to improve safety and ergonomics for workers preparing pallets of polymer bags to be taken from the warehouse to the production line.
The work cycle includes:
– the formation of the pallet to be taken to the production line involves picking up sacks weighing 25 kg from several pallets
– carrying the formed pallet from the warehouse to the production line
– lifting each sack from the pallet and placing it on the hopper grid
– lifting and emptying the sack into the hopper.
For many years, employees used only a hand pallet truck to transport the pallet from the warehouse to the production line and took turns lifting bags while the pallet was being formed. Emptying the sack into the hopper was particularly tiring and in the case of workers with limitations, 2 men were needed.
Constant production was almost impossible, due to the objective difficulty for operators to maintain a constant production level of manual load handling operations.
INDEVA SOLUTION: a Liftronic Mobile manipulator
Scaglia INDEVA’s proposal to adopt a single solution for all phases of the above work cycle was immediately welcomed by the company managers with enthusiasm; after the implementation of a Liftronic Mobile unit the enthusiasm even grew because the expectations in terms of improved productivity, safety and ergonomics were exceeded by the facts.
A single man, even if with limitations for the manual handling of loads, can form the pallet in less time than before; then the same man transports the pallet from the warehouse to the line; when he reaches the first hopper he lifts the bag using the suction cup gripping system, and while the bag is suspended he empties it without touching it with his hands; he, then, in the same way, loads all the 8 hoppers of the line; the operator can carry out the whole cycle effortlessly while the production rhythm is kept constant during the whole working day. Absenteeism due to manual handling of loads is drastically reduced and the productivity of the entire production cycle is significantly increased.
INDEVA’s Liftronic Mobile is the modern solution with the fastest return on investment for eliminating health and productivity problems related to manual handling of loads in logistics processes in the warehouse and production area.
