BOX MANUFACTURING METHOD AND BOX MANUFACTURING SYSTEM

To provide a box manufacturing method and a box manufacturing system which can reduce the rate of manufacturing defective products, improve manufacturing efficiency, and achieve cost reduction.SOLUTION: A box manufacturing method comprises: conveyance means 2 for conveying a sheet material 10; folding guide mechanisms 3, which are provided on both left and right sides along the conveyance means 2, for folding the sheet material 10 conveyed by the conveyance means 2 at predetermined positions; control means 4 for controlling the operation of the folding guide mechanisms 3; detection means 5 for detecting inclinations of left and right sheet end sides constituting joint parts 12 of a box body 11 formed of a sheet material, which has been folded by the folding guide mechanisms 3; and correction means 6 for correcting the shape of the box body formed by the folding guide mechanisms after the box body has been shaped. The control means 4 automatically adjusts the operation of at least one of the conveyance means 2 and the folding guide mechanisms by feedback control on the basis of the inclinations detected by the detection means 5.SELECTED DRAWING: Figure 1 【課題】不良品の発生率を低減でき、生産効率の向上、コスト低減を実現できる製函方法、製函システムを提供せんとする。【解決手段】シート材１０を搬送する搬送手段２と、搬送手段２に沿って左右両側に設けられ、該搬送手段２により搬送されるシート材１０を所定の位置で折り畳むための折り曲げ案内機構３と、折り曲げ案内機構３の動作を制御する制御手段４と、折り曲げ案内機構３により折り畳まれたシート材よりなる箱体１１の接合部１２を構成する左右のシート端辺の傾きを検出する検出手段５と、折り曲げ案内機構により形成された箱体の形状を形成後に矯正する矯正手段６とを備え、検出手段５により検出される傾きに基づき、制御手段４が搬送手段２及び折り曲げ案内機構３の少なくとも一方の動作をフィードバック制御で自動的に調整する。【選択図】図１
