Cell controller and production system for managing working situation of a plurality of manufacturing machines in manufacturing cell

A cell controller, which is communicably connected to a host computer having a database and which controls a manufacturing cell containing a plurality of manufacturing machines, the cell controller comprising:

• a plurality of sensors which detect a state of each of the plurality of manufacturing machines;
• a state storing unit which stores the state of each of the manufacturing machines detected by the sensors;
• a breakdown information acquiring unit which is configured to acquire breakdown information of each of the manufacturing machines, from state information of each of the manufacturing machines, which is stored in the state storing unit;
• an input unit which enables an input of recovery operation information to the cell controller when each of the manufacturing machines stops;
• a recovery operation information storing unit which stores the recovery operation information of each of the manufacturing machines, which is input by the input unit;
• a correlation data generating unit which is configured to
• for each of the manufacturing machines, generate correlation data obtained by correlating (i) the breakdown information acquired by the breakdown information acquiring unit with (ii) the recovery operation information stored by the recovery operation information storing unit, and
• transmit the generated correlation data to the database;
• and
• a data discriminating unit which is configured to compare the recovery operation information input from the input unit to the recovery operation information storing unit, with the plurality of correlation data accumulated in the database,
• wherein
• when the data discriminating unit finds out recovery operation information similar to the recovery operation information input to the recovery operation information storing unit, from among the plurality of correlation data accumulated in the database, the data discriminating unit is configured to send the similar recovery operation information and the breakdown information associated with the recovery operation information, to an output unit.
