Next, the display processing unit 91c causes the management display unit 94 to display the product information Im and the operation status information Ir included in the production information Ip in the corresponding equipment information sections 111 and 111R as equipment information (ST5: equipment information display process).

Next, in the management display unit 94, the display processing unit 91c causes the lane information sections 114 and 114R to display the colors corresponding to the operation status of the transport lanes 5, 5F and 5R included in the operation status information Ir (ST6: lane color display). Process). Next, in the management display unit 94, the display processing unit 91c causes the warning information sections 112 and 112R to display the contents of the warning information Iw notified from the corresponding devices M1 to M10 (production equipment) in combination with figures and colors (ST7). : Warning display process).

In FIG. 6, the display processing unit 91c then causes the management display unit 94 to display the pointer 115 linked to the input device, and determines whether or not the pointer 115 is superimposed on the work information sections 113 and 113R (ST8). When the pointer 115 is superimposed on the work information compartments 113 and 113R (Yes in ST8), the display processing unit 91c is connected to the devices M1 to M10 (production equipment) corresponding to the work information compartments 113 and 113R in the management display unit 94. The board ID (identification information) of a certain board 4 (work) is displayed on the identification information frame 116 (ST9: identification information display step).

When the pointer 115 is not in the work information sections 113 and 113R (No in ST8), or after displaying the board ID (identification information) in the identification information display step (ST9), the display processing unit 91c then uses the management display unit 94. In, the pointer 115 linked to the input device is displayed, and it is determined whether or not the pointer 115 is superimposed on the equipment information sections 111 and 111R (ST10). When the pointer 115 is superimposed on the equipment information compartments 111 and 111R (Yes in ST10), the equipment information of the devices M1 to M10 (production equipment) corresponding to the equipment information compartments 111 and 111R is displayed in the equipment information frame 117. (ST11: Equipment information frame display process).

In the equipment information acquisition process (ST1), in each of the devices M1 to M10 of the component mounting line 1, the start / end of work on the board 4, the start / end of loading / unloading of the board 4, and the start / end of switching of work target products are performed. It is executed at the timing when the production information Ip is transmitted from the devices M1 to M10 due to changes in the production status such as the end, the occurrence / end of parts supply, and the occurrence / end of trouble stop. Alternatively, when a predetermined time has elapsed from the collection of the previous production information Ip, the equipment information acquisition unit 91a issues a transmission command to each of the devices M1 to M10 to acquire the production information Ip.

Then, when there is a change in the production status in the component mounting line 1 (production line), the load quantity display process (ST3), the work color display process (ST4), the equipment information display process (ST5), and the lane color display process (ST6) are performed. ), The warning display step (ST7) is executed according to the change in the production status. Alternatively, when the operator operates the input device and the pointer 115 is superimposed on the work information compartments 113, 113R or the equipment information compartments 111, 111R, the identification information display step (ST9) or the equipment information frame display step ( ST11) is executed.

As described above, the number of cargoes displayed (ST3), the work color display process (ST4), the equipment information display process (ST5), the lane color display process (ST6), the warning display process (ST7), and the identification information display process (ST9). ), The equipment information frame display process (ST11) is a display process for displaying the production status of the component mounting line 1 (production line) on the management display unit 94 (display unit).

As described above, the management computer 3 (equipment information acquisition unit) of the present embodiment has the equipment information acquisition unit 91a for acquiring production information Ip from individual production equipment (devices M1 to M10) and the production line (parts). Production that is equipped with a display unit (management display unit 94) that displays the production status of the mounting line 1), and works on the work (board 4) in order with a plurality of production facilities to produce a product (mounting board).
