Corrugated cardboard sheet manufacturing system

A corrugated fiberboard sheet manufacturing system comprising:

• production state information acquisition means for acquiring production state information related to a production state of a corrugated fiberboard manufacturing device;
• a process controller including control value information acquisition means for acquiring control value information of a control element of the corrugated fiberboard manufacturing device which affects a warped amount of a manufactured corrugated fiberboard, and control means for feedforward-controlling the control element by using the initial control value;
• warping information acquisition means for acquiring warping information related to the warped amount of the corrugated fiberboard;
• storage means for storing a plurality of actual data sets including at least the production state information, the control value information, and the warping information;
• a pre-control table in which a standard control value of the control element is set according to the production state;
• a correction table for setting an initial control value by correcting the standard control value;
• and
• updating means for updating the correction table by extracting, when a certain amount of actual data sets is accumulated in the storage means, an actual data set including the warping information related to a minimum warping amount from the plurality of actual data sets stored in the storage means and reflecting the extracted actual data set in the correction table.
