DETECTION SYSTEM, DETECTION DEVICE, DETECTION METHOD, PROGRAM, AND LEARNED MODEL

To detect completion of a gate seal more accurately.SOLUTION: A detection system comprises: a molding apparatus that molds a molded product; and a detection device that detects a state of the molding apparatus. The molding apparatus includes: a die section in which a flow channel and a cavity communicating with the flow channel through a gate are formed; an injection section that performs a charging operation that charges a molding material in a molten state into the cavity from the flow channel, a pressure retaining operation that retains a pressure of the molding material charged into the cavity, and a pressure retaining release operation that releases the retention of the pressure of the molding material; and a pressure sensor that detects the pressure of the molding material in the flow channel. The detection device includes: a data acquiring section that acquires time series data on pressures detected by the pressure sensor; and a detection section that detects, after the pressure retaining operation, whether or not sealing of the gate is completed based on the time series data before the pressure retaining release operation.SELECTED DRAWING: Figure 1 【課題】より正確にゲートシールの完了を検出する。【解決手段】 成形品を成形する成形装置と、前記成形装置の状態を検出する検出装置と、を備える検出システムであって、前記成形装置は、流路と、ゲートを介して前記流路と連通されるキャビティと、が内部に形成された金型部と、前記流路から前記キャビティへ溶融状態の成形材料を充填する充填動作と、前記キャビティに充填された前記成形材料の圧力を保持する保圧動作と、前記成形材料の圧力の保持を解除する保圧解除動作と、を行う射出部と、前記流路における前記成形材料の圧力を検出する圧力センサと、を有し、前記検出装置は、前記圧力センサにより検出される圧力の時系列データを取得するデータ取得部と、前記保圧動作後、前記保圧解除動作前の前記時系列データに基づいて、前記ゲートのシールが完了したか否かを検出する検出部と、を有する、検出システム。【選択図】 図１
