More specifically, the completion time calculation unit 51e determines the remaining amount of cream solder P used in the printing machine M1 of the component mounting line 5 (or the remaining amount of adhesive used in the mounting machines M2 and M3). Based on the solder consumption rate Rc (or adhesive consumption rate) stored in the management storage unit 52, the preparation completion time Tr for completing the preparation of the replenishment cream solder P (or adhesive) is calculated. Alternatively, the completion time calculation unit 51e completes the preparation of the replenishment cream solder P (or adhesive) based on the number of produced sheets (number of printed sheets) and the solder consumption speed Rc (or adhesive consumption speed). Tr is calculated.

  The solder consumption rate Rc is the consumption amount of the cream solder P per unit time or per mounting board, and is obtained based on the past production results, the mask opening area, and the mask thickness. In other words, the completion time calculation unit 51e receives from the material storage 7 based on the number of produced mounting boards and the amount of material consumed per soldering board to be produced (solder consumption speed Rc). It becomes a preparation completion time calculation unit for calculating preparation completion time Tr for completing preparation for taking out the container (solder pot 13).

  Alternatively, the completion time calculation unit 51e sets the solder pot 13 in the printing machine M1 according to the past production results, or supplies the cream solder P accommodated in the solder pot 13 to the printing machine M1 until it is consumed. Is known, the preparation completion time Tr is calculated based on the production start time and the consumption time. The calculated preparation completion time Tr is stored in the management storage unit 52. When the preparation completion time Tr is calculated, the material preparation instruction unit 51d may instruct the preparation of the solder pot 13 (container) to be taken out to be completed before the preparation completion time Tr.
