Abstract

Energy regeneration in automated high bay warehouse with stacker cranes

Highlights

  • Automated high bay warehouses are one of the most popular choices for many types of warehousing purposes. They are typically high-rise storage units with a relatively small ground plan, using traditional Crane-Based Automated Storage and Retrieval System (CBAS/RS), which usually consist of conveyors, racks and automated Storage/Retrieval (S/R) machines [1]

  • For mini-load warehouses a Shuttle Based Storage and Retrieval System (SBS/RS) was developed, which is a branch of AVS/RS technology [3, 4]

  • The comparison of effectiveness of CBAS/RS and AVS/RS was studied by Sunderesh et al [14] and Ekren et al [15]

Summary

Introduction

Automated high bay warehouses are one of the most popular choices for many types of warehousing purposes. In recent time instead of CBAS/RS Autonomous Vehicle Storage and Retrieval Systems (AVS/RS) which is a relatively new technology for automated Unit-Load warehouses, has been implemented, mostly in Europe [2]. For mini-load warehouses a Shuttle Based Storage and Retrieval System (SBS/RS) was developed, which is a branch of AVS/RS technology [3, 4]. Performance evaluation and comparison of AVS/RS and CBAS/RS material handling systems of automated high bay warehouses is an actual research theme. For the purpose of storage of dairy products the warehouse is cooled to 5 °C It consists of 4 aisles with racks on both sides (Fig. 1). The load, which must be stored (the tote), is located on a cargo pallet (Fig. 4) and transferred to the corresponding stacker crane by means of an automated conveyor.
