[0028] As can be seen from the above description, the proximity sensor 13 is used to determine whether the workpiece placing tool 2 on the feeding end of the belt conveyor 1 is placed with a workpiece. If no workpiece is placed, the belt conveyor 1 will not perform the conveying operation, thereby ensuring the continuity of workpiece conveying. The presence / absence sensor 14 is used to determine whether the workpiece placing tool 2 on the discharging end of the belt conveyor 1 is placed with a workpiece. If no workpiece is placed, the workpiece taking equipment near the discharging end of the belt conveyor 1 will not operate, thereby ensuring the effectiveness of the workpiece taking equipment.

[0029] Please refer to Figure 1 , further, the discharging end of the belt conveyor 1 is provided with a position sensor 15, and the detection end of the position sensor 15 faces the workpiece placing tool 2.

[0030] As can be seen from the above description, the position sensor 15 is used to determine whether the workpiece placing tool 2 on the discharging end of the belt conveyor 1 is in place, thereby suspending the conveying operation of the belt conveyor 1, so that the workpiece taking equipment near the discharging end of the belt conveyor 1 takes away the workpiece on the workpiece placing tool 2.

[0031] Please refer to Figure 2 , further, the workpiece placing end of the workpiece placing tool 2 is provided with a detection protrusion 21 adapted to the detection end of the position sensor 15.

[0032] As can be seen from the above description, the position sensor 15 determines whether the workpiece placing tool 2 is in place by detecting the detection protrusion 21 on the workpiece placing tool 2.
