PROBLEM TO BE SOLVED: To provide a bag manufacturing and packaging machine capable of suppressing an erroneous discrimination of meshing in a case where operation is interrupted and started again thereafter.SOLUTION: A bag manufacturing and packaging machine 10 comprises: a longitudinal seal device 24 which applies thermal seal processing to a molded film, thereby forming a first seal region; a lateral seal device 30 which holds the film with the first seal region formed thereon and applies seal processing to the film, thereby forming a second seal region; an encoder 32a and a control unit 50 for acquiring operation data relating to an operation amount during the holding operation of the lateral seal device 30; and the control unit 50 by which, in a case where the operation data are equal to or higher than a threshold, it is discriminated that an object is meshed in the second seal region. In a case where operation of the bag manufacturing and packaging machine 10 is interrupted and started again thereafter, the control unit 50 sets the threshold greater than that before the operation interruption.SELECTED DRAWING: Figure 4 【課題】運転中断の後に運転が再開された場合における噛込みの誤判定を抑制することができる製袋包装機を提供する。【解決手段】製袋包装機１０は、成形されたフィルムに熱シール処理を施して第１シール領域を形成する縦シール装置２４と、第１シール領域が形成されたフィルムを挟み込むと共に、当該フィルムにシール処理を施して第２シール領域を形成する横シール装置３０と、横シール装置３０の挟み込み動作時の動作量に関する動作データを取得するエンコーダ３２ａ及び制御部５０と、動作データが閾値以上の場合に、第２シール領域における物品の噛込みがあると判定する制御部５０と、を備える。制御部５０は、製袋包装機１０の運転中断の後に運転が再開された場合に、運転中断の前よりも閾値を大きく設定する。【選択図】図４
