Description

Technical Field

[0001] This utility model relates to the field of warehousing equipment, specifically a three-dimensional circulating warehousing and transportation device. Background Technology

[0002] In modern industrial production, the demand for continuous automated storage and transportation of palletized materials is increasing. This is especially true in industries such as food processing, where efficient and precise material handling systems directly impact production efficiency and product quality. Taking bread production as an example, the proofing process is one of the key steps in bread making; the quality of proofing directly affects the taste and quality of the bread.

[0003] Traditional bread proofing systems often employ a manual pallet loading and unloading method using trolleys. In this system, workers manually move pallets containing bread dough onto trolleys, push the trolleys to the proofing area, and then manually unload the pallets for further processing after proofing. This manual operation method has several drawbacks. Firstly, manual pallet loading and unloading is labor-intensive and inefficient, severely limiting production capacity. With the increasing market demand for bread, this inefficient material handling method can no longer meet the needs of large-scale production. Secondly, manual operation makes it difficult to ensure consistent placement and force when loading and unloading pallets, easily leading to uneven compression or vibration of the bread dough during proofing, affecting the consistency of proofing results and consequently impacting product quality stability.

[0004] Furthermore, rising labor costs have placed a heavy economic burden on businesses. To address these issues, the industry urgently needs a warehousing and transportation system that can achieve automated continuous production, increase capacity, reduce labor costs, and ensure product quality stability.
