Un pallet è una struttura utilizzata per il trasporto di merci, disponendole su di esso in modo stabile. Questo permette la facile movimentazione sia in fase di sollevamento di un carrello elevatore, un martinetto, un caricatore frontale o un generico dispositivo di sollevamento. Un pallet è generalmente realizzato in legno, ma dal punto di vista dell’impatto ambientale, esso può essere riutilizzato più volte, ma il materiale non può essere riciclato. Al fine di superare il problema di cui sopra, tentiamo di utilizzare cartone per la realizzazione di pallet. Il cartone, infatti, assicura una maggior sostenibilità e riciclabilità. Rispetto ai pallet di legno. Questo tipo di pallet in pratica appartiene alla categoria di eco pallet. La trasformazione di lastre piane in strutture tridimensionali è molto in voga negli ultimi anni, in numerosi campi industriali. Le forme d'arte secolari di origami e kirigami potrebbero offrire soluzioni eleganti, che prevedono solo piegature e tagli per trasformare le elementi piani in complesse geometrie spaziali. Sebbene tali tecniche siano limitate da un vincolo inerente all'abilità di sviluppo, il design razionale dei motivi di piega e taglio consente lo spostamento della forma da superficie a spazio. In tal modo, combinando i benefici del kirigami e del nido d'ape, possiamo ottenere risultati e risultati essere verificato dal software di simulazione. In questa tesi realizziamo la struttura a nido d'ape usando il kirigami approccio per adattarsi all'applicazione di pallet.

Abstract
A pallet is a flat transport structure, which supports goods in a stable fashion while being lifted by a forklift, a pallet jack, a front loader, a jacking device, or an erect crane. A pallet is the structural foundation of a unit load which allows handling and storage efficiencies they are generally made from wooden logs, but from the environmental perspective it cannot be recycled. In order to overcome the above issue we attempt to use recyclable and reusable paper board which is more sustainable than the wooden logs. These kind of pallets basically belong to the category of ECO-PALLETS. Transforming flat sheets into three-dimensional structures has emerged as an exciting manufacturing paradigm on a broad range of length scales. Among other advantages, this technique permits the use of functionality inducing planar processes on flat starting materials, which after shape-shifting, result in a unique combination of macro-scale geometry and surface topography. The centuries old art forms of origami and kirigami could offer elegant solutions, involving only folding and cutting to transform flat papers into complex geometries. Although such techniques are limited by an inherent develop ability constraint, the rational design of the crease and cut patterns enables the shape-shifting of (nearly) inextensible sheets into geometries. Thereby combining the benefits of kirigami and honeycomb we can achieve results and can be verified by simulation software. We in this thesis make honeycomb structure using kirigami approach to fit in the application of pallets.File | Dimensione | Formato | |
