The motor 70 causes the chain 67 to run at a pitch P corresponding to the loading width of one press part 2 on the pallet 5 each time the press parts 2 are loaded onto the pallet 5. Each time one pallet 5 becomes full, the next pallet 5 is rapidly transported to the loading position in conjunction with the operation of the feeding means B.

In the press parts loading device described above, each suction cup 1 of the unloader 14, the upright means 4, and the feeding means 6
7, 35, and 56 are all vacuumed and adsorbed to the press part 2.

Next, the operation of the press parts loading device will be explained.

In FIG. 2, each time press processing is performed by the press machine 1, the unloader 14 picks up the press part 2 in response to the upward movement of the upper mold 12, and the press part 2 is placed in a lying position on the fixed carrier 24 of the conveyor device 15. Give it as is. In response to this transfer, the conveyor device 15 operates, and the fixed carrier 2
4, the press part 2 is transported to the position of the lifter 28. At this time, the rotating carrier 25 also moves to the transport end of the conveyor device 15 at the same time.

The lifter 28 operates in response to the conveyance operation of the conveyor device 15, and lifts the press part 2 from the fixed carrier 24. Then, the quality (good or bad) of the press part 2 on this lifter 28 is inspected. On the other hand, when the press part 2 already conveyed to the conveying end by the revolving carrier 25 is held by the upright means 4, both carriers 24 and 25 remain empty, and the conveyor device 15 performs a return operation. The fixed carrier 24 is on the unloader 14 side, and the rotating carrier 25 is on the lifter 28 side.
Return to bottom. The lifter 28 descends in response to this return operation and transfers the press part 2 from the fixed carrier 24 to the rotating carrier 25.

When the rotating carrier 25 receives the pressed part 2 from the lifter 28, the rotating device 36 operates during the conveyance, and the rotating carrier 25 rotates 2θ degrees in the opposite direction depending on whether the press part 2 is a left or right 7-ender. Change the direction of 2 and send it to the conveyance end. This turning is an operation for making sure that the tire house side of both the left and right fenders is on top when the press parts 2 are loaded onto the pallet 5 by the feeding means 6.

In other words, in the pressed part 2, the tire houses of both the left and right fenders are oriented in the same direction (in the case of this example, the direction opposite to the conveyance means 3) due to the press work, but this Since the press part 2 is turned midway, when the press part 2 is raised in a direction perpendicular to the conveyance direction 10 by the upright means 4, the tire house faces upward in both the left and right fenders. Therefore, the pressed parts 2 can be fed as they are by the feeding means 6 in the same direction as the conveyance direction 10 and loaded onto the pallet 5.

The above is the operation of transporting the press part 2 by the four-way transport means 3.Next, the raising means 4 moves the press part 2 to the transport means 3.
It is activated when it is conveyed to the conveying end.

That is, when the pressed part 2 is a right fender, the suction cup 65, which is directed downward by the operation of the cylinder device 41 for raising and lowering, is lowered by the operation of the cylinder device 44 for raising and lowering, in the raising means 4 on the right side in FIG. It adsorbs to the press part 2 and then rises to hold the press part 2. If this press part 2 is defective, the upright means 4 is moved above the discharge conveyor 11 by the operation of the moving cylinder device 49 in the defective product removal means 9 on the right side, and is held by the suction cup 35 in the upright means 4. is released and is discharged as a defective pressed part 8.

Further, when there is no abnormality in the press part 2 held by the erecting means 4, the erecting cylinder device 41 operates to erect the press part 2. While the right-side upright means 4 and the defective product removal means 9 are in operation, the left-hand upright means 4 is in a retracted position where it is withdrawn from above the conveyance means 3 due to the operation of the defective product removal means 9 that supports it.

On the other hand, if the pressed part 2 is the left 7 ender, if it is a defective product, it will be ejected by the operation of the right-hand raising means 4 and the defective product removal means 9, but if there is no abnormality, then the left-hand raising means 4 will be ejected. operates to hold and raise the press part 2.

Next, the feeding means 6 is activated when the upright means 4 raises the press part 2. First, if the press part 2 is the right fender, the left arm 57 moves to the right in FIG. The suction cup 56 attracts the pressed part 2, and the pressed part 2 is passed from the upright means 4 to the feeding means 6. Then, this left arm 57 moves to the left until the press parts 2 are at a position corresponding to the loading position of the pallet 5, while the arm 57 of the upright means 4 is placed in a prone position. Then, the traveling body 61 supporting the arm 57 via the slider 54 travels to the pallet S side, loads the press parts 2 onto the pallet 5, the suction by the suction cup 56 is released, the slider 54 slides to the left, and the suction cup 56 leaves the press part 2, and the traveling body 61 returns to the conveyance means 3 side. Then, the pallet moving means 7 moves the pallet 5 every time the loading of the press parts 2 is completed.
Move / pitch.

In addition, in the above-mentioned feeding means 6, if the press part 2 is the left fender, the arm 57 on the right side in FIG. Become. In this case, the pitch feeding direction of the pallet 5 is opposite to that for the right fender.

In addition, when the discharge conveyor 11 is provided on the left side as shown by the chain line in FIG. 7, the defective product removal means 9 on the left side discharges the defective pressed parts 8 related to the left and right fenders.

(Effects of the Invention) According to the present invention, defective press parts are taken out to the discharge position by supporting and moving the entire press part raising means, so even if there is a defective product, there is no need to stop the press machine. , it is possible to sequentially transport press parts without any abnormality and load them onto the pallet in an upright state, and the above-mentioned raising means for raising good pressed parts also has the function of picking up defective products from the conveyance means, so it is possible to eliminate defective products. The means for this becomes simple.
