Abstract
【解決手段】所定形状のセパレータ40を外周面311で保持して回転することで搬送する円柱状の搬送ドラム310,320と、前記セパレータ40と重なるように搬送ドラムの接線方向へ所定形状の正極22を搬送する電極搬送部200と、を有し、搬送ドラムの外周面に対応して、正極が投入される部位よりも搬送ドラムの回転方向上流側に非回転的に位置してセパレータを吸着する吸着領域A2と、正極が投入される部位よりも回転方向下流側に非回転的に位置してセパレータを離間させる非吸着領域A3とが区画され、外周面が吸着領域において吸着したセパレータを外周面の回転によって非吸着領域へ搬送して、外周面からセパレータを離間させて正極に受け渡すことで正極とセパレータを回転方向下流側から順次積層する積層装置である。
