PRODUCTION LINE IN PLANT FACTORY

To provide a technique that efficiently perform work such as maintenance without stopping the operation of a production line.SOLUTION: A production line in a plant factory comprises: cultivation paths which are sequentially conveyed in a row direction in the state where a plurality of cultivation trays 130 holding plants to be cultivated are held are connected, and cultivate plants through a process of conveying the cultivation trays 130; functional trays 132,134,136,138 or the like which are assembled into the row of a plurality of the cultivation trays 130 connected in the cultivation paths, and function according to other objectives different from plant cultivation by being conveyed in the cultivation paths while substituting for the cultivation trays 130.SELECTED DRAWING: Figure 2 【課題】生産ラインの稼働を止めることなく保守等の作業を効率的に行う技術を提供する。【解決手段】植物工場内生産ラインは、栽培対象の植物が保持された栽培トレイ１３０を複数枚連ねた状態で列方向に順次搬送し、栽培トレイ１３０が搬送される過程を通じて植物を栽培する栽培経路と、栽培経路内で複数枚に連なる栽培トレイ１３０の列内に組み入れられ、栽培トレイ１３０に代替して栽培経路内を搬送されることにより、植物の栽培とは別の目的に応じた機能を果たす機能トレイ１３２，１３４，１３６，１３８等とを備える。【選択図】図２
