At this time, the elevator 230 of the tray conveying member 200 ascends and sucks the lowermost tray 13 of the loading unit 101, and the sucked tray 13 moves to the lower end of the pick- The elevator 230 is lifted up again to mount the tray 13 on the pick-up part 102 and provide the insert part 11 to the first orthogonal robot 300 side.

Repeating this process causes the tray 13 of the pickup unit 102 to be provided with all of the insert components 11 to become the empty tray 13 and to provide the insert component 11 to the pickup unit 102 side The empty tray 13 is transferred to the discharging portion 103 side by the conveying plate 210 so that the empty tray 13 is mounted to the discharging portion 103 through the elevator 230, Respectively.

6, when the tray 13 is mounted on the pick-up unit 102 by the tray transfer member 200 to provide the insert part 11, the first picker 310 of the first orthogonal robot 300, The first picker 310 sucks the insert part 11 while moving to the position for picking up the insert part 11 through the second guide 320 and the third guide 330. The insert part 11 The first picker 310 sucking the first picker 310 moves toward the work table 120 through the second guide 320 and the third guide 330 to seat the insert part 11 on the work table 120.

At this time, the first picker 310 seats the insert parts 11 of a single or different material through the pair of suction tips 312 to be combined with the work table 120.

In this state, the second picker 410 of the second orthogonal robot 400 sucks the insert part 11 of a single or different material, which is seated on the workbench 120, 5 is guided to the injection molding position of the injection molding machine 10 through the guide 430 to feed the sucked insert parts 11 to the injection molding machine 10, The second picker 410 is sucked and then put on the work table 120.

The injection product 12 placed on the workbench 120 is delivered to the outside through the transfer unit 130 or selectively transferred to the cutting unit 140 to complete the injection molding.

As described above.
