[Prior art]
In the conventional automobile manufacturing process, since the production instruction is one system, the members including the respective S / A parts are assembled in order according to the specification form of the same vehicle type, and a certain production amount is produced. When changing to production of a different vehicle type, it was necessary to assemble S / A parts according to the specification mode of the vehicle type.
[0003]
For this reason, since the manufacturing process is carried out as a single process for each same vehicle type, the daily production amount of S / A parts used for the vehicle type changes when the vehicle type to be manufactured changes. And since the jigs for assembling S / A parts also require different combinations of jigs for each vehicle type, it is necessary to prepare S / A component assembling jigs corresponding to the number of vehicle types.
[0004]
Conventional S / A component assembly jigs are stored in a flat jig stocker corresponding to one vehicle type, and each time the vehicle type changes, the jig placement location corresponding to that vehicle type is set. I had to move and work. For example, in the prior art shown in FIGS. 6 and 7, the jig set A for the vehicle type A, the jig set B for the vehicle type B, and the jig set C for the vehicle type C are in different locations. The car part W of A is performed by the jig set A, and each time the car type is changed, the S / A part is assembled.
[0005]
In addition, when there is a model change of the vehicle type or a change in the production amount for each vehicle type, it is necessary to change the jig arrangement location by examining the jig arrangement locations of several types that can be handled.
[0006]
[Problems to be solved by the present invention]
In the conventional jig placement place on a flat surface, there is a problem that the operator needs to move to a necessary jig set placement place every time the vehicle type changes. In addition, the jig set placement place occupies the factory with a planar area as many as the number of models, and if the number of models increases or changes, there is a problem that the installation space of the factory equipment increases accordingly, and the operating area is narrow There was a problem of becoming.
[0007]
Further, when the number of vehicles produced for each vehicle type is changed, there is a place where a jig is placed without a corresponding vehicle model and there is a problem that usage efficiency is poor.

[0015]
Each pallet 5 has a rectangular panel shape in plan view. In this embodiment, the length L5 is 3080 mm, and the width W5 is 650 mm. A mounting rail 50 is provided across the width direction at the center of the longitudinal surface of the pallet 5, and the component support members 4 are attached to the mounting rail 50 so as to be freely mounted.
[0016]
The component support member 4 includes two rail slide portions 40, an adjustment cylinder 41 provided to connect the two rail slide portions 40, a rotation fulcrum portion 42, and two receiving pieces 3. . Each of the two receiving pieces 3 has a piece cylinder 30 that can be opened and closed. The receiving piece 3 is opened and closed by expansion and contraction of the piece cylinder 30 so that an automobile part W such as a fender can be grasped and supported. One receiving piece 3a of the two receiving pieces is rotatably provided at the rotation fulcrum portion 42, and opens to the outside by extension of the adjusting cylinder 41 and rotates to be folded inward by shortening.
[0017]
The component support member 4 is slidably attached to the mounting rail 50 of the pallet 5 in the width direction W of the pallet 5 by the two rail slide portions 40. The two rail slide parts 40 can be slid independently of each other, and the distance between the two rail slide parts 40 is the maximum in the state where the automobile part W such as a fender is attached, and the rotating part 6 of the jig rotation switching device 1 is rotated.

[0018]
Next, the operation of the embodiment of the present invention will be described. In the embodiment shown in FIGS. 1 and 2, the automobile part W is set only on the part support member 4 of one pallet 5. As another embodiment, as shown in FIG. 5, three types of automobile parts W can be set on each part support member 4 of each of the three pallets 5 attached to the three pallet mounting surfaces 60.
[0019]
Each of the component support members 4 is slidable with respect to the width direction of the pallet 5 and the receiving piece 3 is provided so as to be foldable and rotatable. Therefore, the component support member 4 corresponds to the shape and length of the automobile component W of each vehicle type. Slide and rotate as appropriate.
[0020]
That is, when the automobile part W such as a fender of one vehicle type is attached to the receiving piece 3, the cylinder rod 410 of the adjustment cylinder 41 of the part support member 4 is extended in accordance with the size of the corresponding automobile part W, and two rail slides It is possible to set the interval between the receiving pieces 3a and 3b according to the size of the vehicle part W of the vehicle type by separating the interval of the portion 40 and opening the rotatable receiving piece 3a to the outside as appropriate. become. The receiving pieces 3 a and 3 b can fix and remove the automobile part W by extending and contracting the piece cylinders 30 and 30. Therefore, it is possible to cope with a plurality of vehicle parts W by adjusting the component support member 4.
