[0039] In various embodiments of the present invention, a trunk among parts of a vehicle will be illustrated as one example.
[0040] As illustrated in FIGS. 2 to 4, the multi-parts autotransferring apparatus according to various embodiments of the present invention is to transfer parts to an assembly line (not illustrated) to be mounted in a car body and includes a body 100 configured to be mounted to be spaced apart from a ground by a plurality of supports 110 and have the part 1 disposed at a lower portion thereof, a vertical moving part 200 configured to be mounted at the lower portion of the body 100 to descend toward the part 1, a horizontal moving part 300 configured to be mounted at a lower portion of the vertical moving part 200 to be advanced and retreated in a front and rear direction (longitudinal direction of a car body) of the part 1, front jig parts 400 configured to be each mounted at both sides of a front of the horizontal moving part 200 and hold both side portions of a front of the part 1, and rear jig parts 500 configured to be each mounted at both sides of a rear of the horizontal moving part 200 and hold both side portions of a rear of the part 1.
[0041] Referring to FIGS. 2 and 3, the body 100 has a rectangular plate and has at least four supports 110 disposed at each corner thereof and is fixed while being spaced apart from a ground, such that the part 1 moving to the assembly line is disposed at the lower portion of the body 100.
[0042] Further, each corner of an upper surface of the body 100 is provided with guide pieces 120 having a hollow which penetrates through each corner, in which the guide pieces 120 have guide bars 212 slidably inserted thereinto.
[0043] The vertical moving part 200 includes a vertical moving member 210 configured to be slidably mounted at the lower portion of the body 100 in a direction of the part 1 and a first motor 220 configured to move the vertical moving member 210 in the direction of the part 1.
[0044] The vertical moving member 210 includes a vertical moving piece 211 configured to be mounted at the lower portion of the body 100 and guide bars 212 configured to be disposed at each corner of the vertical moving pieces 211 and slidably inserted into the hollows of the guide pieces 120 which are disposed at each corner of the body 100.
[0045] The first motor 220 includes a first gear (not illustrated) disposed at a rotating shaft thereof, in which the first gear is meshed with a rack gear (not illustrated) which is vertically disposed at the vertical moving member 210.
[0046] That is, the first gear rotates at the time of a rotation of the first motor 220, the rack gear descends or ascends by the first gear, and the vertical moving member 210 moves vertically by the rack gear.
[0047] Therefore, in the vertical moving part 200, when the first motor 220 rotates, the vertical moving piece 211 of the vertical moving member 210 descends by the first motor 220. In this case, the vertical moving member 210 is disposed at the lower portion of the body 100 to be close to the moving part 1 while vertically descending by the guide piece 120 of the guide bar 212.
[0048] The horizontal moving part 300 includes a horizontal moving member 310 configured to be disposed at the lower portion of the vertical moving part 200 and disposed to be advanced or retreated in a front and rear direction (longitudinal direction of a car body) of the part 1 and a second motor 320 configured to advance or retreat the horizontal moving member 310 in a front and rear direction of the part 1.
[0049] In this configuration, the horizontal moving part 300 is provided with a screw shaft 330 configured to be disposed at the lower portion of the vertical moving part 200 in the front and rear direction of the part 1 and rotate by the second motor 320 and the horizontal moving member 310 is advanced or retreated along the screw shaft 330 at the time of a rotation of the screw shaft 330 while the horizontal moving member 310 being coupled with the screw shaft 330.

That is, the plurality of rear jigs 520 press and hold the rear side portion of the part 1 using the rear pressing piece having the clamp shape.
[0061] Therefore, in the rear jig part 500, when the part 1 moves to the lower portion of the body 100, the rear rotating member 510 rotates by driving the fourth motor 430, such that the rear jig 520 for a part meeting a car model among the plurality of rear jigs 520 having various sizes and lengths which are disposed at the side portion of the rear rotating member 510 is disposed to be toward the part 1. As the hydraulic cylinder 521 is actuated in this state to rotate the rear jig 520, both side portions of the rear of the part 1 are each held.
[0062] As illustrated in FIG. 8, the width moving part 600 includes rack gears 610 configured to be each disposed at the rear jig parts 500 which are each disposed at both side portions of the rear of the horizontal moving part 300 to correspond to each other, a pinion 620 configured to be meshed between the rack gears 610 which are each disposed at the rear jig part 500, and a fifth motor 630 configured to rotate the pinion 620.
[0063] That is, in the width moving part 600, when the pinion 620 rotates by the fifth motor 630, the rack gear 610 disposed at the rear jig parts 500 moves and the rear jig parts 500 move in a direction corresponding to each other, along with the rack gear 610.
[0064] According to the multi-parts autotransferring apparatus for a vehicle according to various embodiments of the present invention having the above configuration, as illustrated in FIG. 9, when the part 1 moves to the lower portion of the body 100, the front and rear jig parts 400 and 500 move to be disposed at the front and rear of the part 1 by the horizontal moving part 300 and a position of the rear jig part 500 moves to meet a rear width of the part 1 by the width moving part 600 and then the rear jig part 500 is disposed at the part 1 by descending the front and rear jig parts 400 and 500 by the vertical moving part 200.
[0065] Next, the front and rear jigs 420 and 520 rotate by the hydraulic cylinders 421 and 521 to hold the front and rear side portions of the part 1.
[0066] Therefore, the multi-parts autotransferring apparatus for a vehicle according to various embodiments of the present invention controls the front and rear jig parts 400 and 500 depending on the length, height, and width of the part to compatibly hold the part 1 having various sizes, thereby increasing the continuity and efficiency of work.
