Smart Inventory 4.0: Advanced version

The Authors of this paper had first conceptualized and then developed the automated picking plant described in the paper “A 4.0 Automated Warehouse Storage and Picking System for Order Fulfillment”, presented by the Authors to the WCE 2021 IAENG Congress and awarded with the “Best Paper Award of the 2021 International Conference of Manufacturing Engineering and Engineering Management”. In the perspective of the continuous improvement of Industry 4.0 they have brought to this first system the significant functional improvements object of this paper. In particular, having found that the loading of the goods in the individual boxes was carried out by the Operators in this factory by using ladders on which they climbed, without the necessary PPE and carrying the load manually, with the consequent risk of falling from such heights (3-6m) to cause even serious physical damage, the Authors first studied and then implemented an automatic loading system. A second problem was then highlighted for the storage of special products such as Food and Pharma, that, unlike what happens in the Beauty Sector (for which the plant was designed), need to remain in specific conditions of temperature and relative humidity. The paper describes how, in this new version, the two parameters are monitored in each single box by means of appropriate sensors that send alerts to the centralized control system when these parameters are outside the preset threshold. In this way, prompt remedial intervention is possible, avoiding the deterioration of the contents of the boxes and the consequent economic damage deriving from their alienation. All this is made possible at acceptable costs thanks to the technologies offered by Industry 4.0 such as modern robotics and Data Centralization via IIoT for monitoring and control.
