Next, the operation of the workpiece suspending and conveying apparatus configured as described above will be described. In this embodiment, when a tailgate is suspended and conveyed as a work, the solid line in FIGS. 1 and 3 is the large tailgate A, and the double-dotted line is the small tailgate B. Is.

As described above, the work storage location 8 shown in FIG. 4 stores a plurality of types of tailgates A and B having different shapes and sizes in a mixed manner. Is specified, and the loading traverser mechanism 11 is input with vehicle type data according to the setup of the production line.

First, when the loading traverser mechanism 11 is in the raised position, the operator places the tailgate A on the work cradle 7 in an oblique state in the carrying-out order, and rotates the work cradle 7 in a horizontal state. Then, the loading traverser mechanism 11 descends.

The main hanger arm 31, the first to fourth hangers arms 21 to 24, and the fifth hanger arm 37 of the loading traverser mechanism 11 descend while being opened outward, and when descending to a predetermined position, the first hanger arm 31 and the fifth hanger arm 37 are moved to a predetermined position, and the The first to third cylinders 20, 28 and 35 are selectively activated.

That is, since the work set at the loading position 3 is the tailgate A 2, the first cylinder 20 and the second cylinder 28 are operated. Therefore, the interlocking member 17 is rotated by the first cylinder 20, and this rotation is converted into reciprocating motion by the interlocking member 17 and transmitted to the first and second connecting rods 18, 19.

Further, the reciprocating motions of the first and second connecting rods 18, 19 are converted into rotary motions by the brackets 14a, 15a, and the first and second rotary support shafts 14, 15 rotate (about 90 °).゜)

Although the first to fourth hanger arms 21 to 24 are simultaneously turned inward by the rotation of the first and second rotation support shafts 14 and 15, the dedicated hanger arm of the tailgate A is the first. Since it is the hanger arm 21, only the support receiving portion 21a enters the lower side of the outer peripheral edge portion of the tailgate A, and the remaining second to fourth hanger arms 22 to 24 are arranged and long enough not to interfere with the tailgate A. Therefore, even if they rotate inward at the same time, they will not swing and interfere with the tail gate A.

At the same time, the rod 29 of the second cylinder 28 is retracted and the protruding arm 27 is rotated downward, so that the third rotation support shaft 25 is rotated, and this rotation causes the main hanger arms 31, 31 to rotate. Inwardly, the support receiving portions 31a, 31a enter the lower side of the outer peripheral edge portion of the tailgate A.

Therefore, the tailgate A is suspended by the four main hanger arms 31, 31 and the two first hanger arms 21, 21 in total, and the loading traverser mechanism 11 rises. The tailgate A is transferred to the next process by being transferred to the work receiving jig 5 waiting at the transfer position 2.

Also, when the work placed on the work cradle 7 according to the unloading order is the tailgate B, similarly, the main hanger arm 31 and the first to fourth hanger arms 21 to 24 of the loading traverser mechanism 11 are similarly. And, the fifth hanger arm 37 descends in a state of being opened outward, and when descending to a predetermined position, the first to third cylinders 20, 28 and 35 are selectively operated according to the vehicle type data.

That is, since the work set at the loading position 3 is the tailgate B 3, the first cylinder 20 and the second cylinder 28 operate. Therefore, the first and second rotation support shafts 14 and 15 rotate (about 90 °) by the first cylinder 20, and the first to fourth hanger arms 21 to 24 simultaneously rotate inward. Since the exclusive hanger arm of the port B is the second hanger arm 22, only the support receiving portion 22a enters the lower side of the outer peripheral edge portion of the tailgate B, and the remaining first, third, and fourth hanger arms. Since 21, 23, and 24 are arranged and have a length that does not interfere with the tailgate B, even if they rotate inward at the same time, they do not interfere with the tailgate B and do not swing.

At the same time, the rod 29 of the second cylinder 28 is retracted and the protruding arm 27 is rotated downward, so that the third rotation support shaft 25 is rotated, and this rotation causes the main hanger arms 31, 31 to rotate. The support receiving portions 31a, 31a rotate inward and enter the lower side of the outer peripheral edge portion of the tailgate B.

Therefore, the tailgate B is suspended by the four main hanger arms 31, 31 and the two second hanger arms 22, 22 in total, and the loading traverser mechanism 11 rises. The tailgate B is transferred to the work receiving jig 5 waiting at the transfer position 2 and is conveyed to the next step.

Further, when the work set in the loading position 3 is the tailgate C, the first cylinder 20, the second cylinder 28, and the third cylinder 35 operate according to the vehicle type data. Therefore, the rotation of the first and second rotation support shafts 14 and 15 by the first cylinder 20 and the rotation of the third rotation support shaft 25 by the second cylinder 28 operate in the same manner as the tailgates A and B described above. However, the support receiving portion 23a of the third hanger arm 23 enters below the tailgate C. At the same time, the fourth rotation support shaft 32 is rotated by the operation of the third cylinder 35, the fifth hanger arms 37 and 37 are rotated inward, and the support receiving portion 37a is located below the tailgate C. enter in.

Therefore, the tailgate C is hung by a total of six hanger arms including the two main hanger arms 31 and 31, the two third hanger arms 23 and 23, and the two fifth hanger arms 37 and 37. Be held. That is, the main hanger arms 31 1 and 31 2 are common to the tailgates A, B, and C.

In addition, in the above-described embodiment, the case where three kinds of hanger arms dedicated to the tailgate are provided has been described, but four or more kinds of hanger arms dedicated to the tailgate may be provided, or the tailgate. Not limited to the above, it can be applied to suspending and transporting large parts such as a trunk lid and a hood.
