 Hereinafter, an embodiment of a component supporting device for an assembly line of the present invention will be described in detail with reference to the drawings. FIG. 1 is a front view of a component support device showing a main part of the present invention, FIG. 2 is a front view showing a state in which a motorcycle is assembled on an assembly line, and FIG. 3 is a perspective view of the component support device. In these drawings, reference numeral 1 is a component supporting device for supporting the engine 2. In this component support device, the engine 2 is supported while being transported on the transport path 3 that constitutes the assembly line, and the body frame 5 is attached to the supported engine 2 as shown in FIG. A front wheel 6 and a rear wheel 7 are attached to the wheel 5, respectively.

In the component support device 1, a support pedestal 10 is rotatably mounted on a conveyance path 3 in a horizontal direction, and left and right first support arms 11 and 11 erected on side portions of the support pedestal 10. In addition, a prism 12 placed horizontally is rotatably supported about its axis m. In this embodiment, the prism 12 is a pentagonal prism.

A lock mechanism 13 for stopping the prism 12 at a predetermined angle is provided on the first support arm 11. In the lock mechanism 13, the rod 13a penetrating the first support arm 11 is biased toward the prism 12 by a spring (not shown), and a side surface of the prism 12 has a groove (not shown) with which the tip of the rod 13a is engaged. It has a formed structure. The lock mechanism 13 stops the prism 12 at any of a plurality of rotation angle positions so that the outer peripheral surfaces 12a, 12b, ... 12e thereof face the component support position A above the prism 12. 12e are mounted on the outer peripheral surfaces 12a, ... 12e of the prisms so as to support different types of engines.

As shown in FIG. 5, one of the above-mentioned component support parts 14 a, ... 14 e is detachably attached to the outer peripheral surface 12 e of the prism 12 by the engine receiving member 15 being detachably attached. ing. That is, a dovetail 16 formed in a reverse taper shape is formed on the outer peripheral surface 12e of the prism, and a dovetail groove 17a that engages with the dovetail 16 is formed on the lower surface of the support base 17 to which the engine receiving member 15 is attached. Has been done. Although only one type of engine receiving member 15 is shown in FIG. 5, a plurality of types of removable engine receiving members 15 are prepared in advance, and one of them is selected to select the prism. It is removably attached to the outer peripheral surface 12e of 12.

A second support arm 19 is attached to the support base 10 at a position displaced by 90 degrees from the first support arm 11. A support member 21 for supporting the engine 2 is slidably attached to the tip of the second support arm 19 via a jig 20 for supporting the engine. One of the two second support arms 19 is rotatable about an axis orthogonal to the axis m of the prism and is also rotatable in the direction of approaching and separating from the engine 2. The position can be adjusted. Then, the one second support arm 19 is forcibly tilted to the engine 2 side by the tilting mechanism 22 using the cam, and the other side second support arm 19 and the component support on the prism 12 are supported. Together with the parts 14a, ... 14e, the engine 2 is firmly fixed in place.

Next, the operation of the component support device of the assembly line having the above configuration will be described. As shown in FIG. 2, the engine 2 is placed on the component support portion 14a of the prism 12 of the component support device 1, and the second support arm 19 is tilted to the engine side via the tilting mechanism 22. The engine 2 is firmly fixed to the component support position A. Then, in this component supporting device, the engine 2 is transferred while being supported and fixed on the transport path 3, and the body frame 5, the front wheels 6 and the rear wheels 7 are attached to the engine 2, respectively. As a result, the main components of the motorcycle are assembled.

Here, when the model of the motorcycle to be assembled is changed, the lock mechanism 13 is released. That is, the rod 13a is pulled toward the front side against the spring force (not shown), and the engagement with the prism 12 is released. Then, the prism 12 is rotated by a predetermined angle so that the component support portion that supports the component of the new model is opposed to the component support position A and is locked again by the lock mechanism 13. In this way, the model changeover setup is completed by a very simple work of simply rotating the prism 12 at an appropriate angle.

If the parts for supporting the components (engine) of the new model are not attached to the outer peripheral surfaces 12a, ... 12e of the prism 12, the engine receiving member 15 is removed from the outer peripheral surface 12e of the prism 12. , Install the receiving member that supports the new model engine using the dovetail groove. In this way, by constructing one component support portion on the outer peripheral surface of the prism 12 in a detachable manner, it is possible to mount more component support portions on the prism 12 than the number of peripheral surfaces of the prism. It can easily handle small-scale production.

It should be noted that the dimensions, materials, shapes, relative arrangements, and the like of the constituent parts described in the present embodiment are intended to limit the scope of the present invention to them unless otherwise specified. It's not an example, it's just an example. For example, in the above embodiment, the case where the support target is an engine has been described as an example, but the present invention is not limited to this, and the support target component may be another member such as a vehicle body frame. In addition, although a pentagonal prism is described as an example in this embodiment, a prism other than 5 such as a triangular prism or a quadrangular prism may be used. Further, in this embodiment, the rotation axis of the prism 12 is taken as the water level surface, but the invention is not limited to this, and the rotation axis may be taken along the vertical surface.
