Abstract

An assembly work conveyor device has a work dolly and a movement driver. The work dolly includes a moving dolly including a plurality of moving portions movable on a movement surface and being movable along an elliptical movement path, and a work board mounted on the moving dolly in a state of extending further to an inner peripheral side of the elliptical movement path than the plurality of moving portions. The movement driver moves the work dolly along the elliptical movement path. An auxiliary support surface is provided on the inner peripheral side of the elliptical movement path along at least a portion thereof. An auxiliary support is provided in the work dolly, the auxiliary support being brought into contact with the auxiliary support surface further on the inner peripheral side of the elliptical movement path than the plurality of moving portions and supporting a gravity of the work board.

Claims

1. An assembly work conveyor device comprising:

a work dolly comprising;

a moving dolly comprising;

a plurality of moving portions movable on a movement surface,

the moving dolly being movable along an elliptical movement path; and

a work board mounted on the moving dolly in a condition extending further to an inner peripheral side of the elliptical movement path than the plurality of moving portions; and

a movement driver moving the work dolly along the elliptical movement path, wherein

an auxiliary support surface is provided on the inner peripheral side of the elliptical movement path along at least a portion of the elliptical movement path, and

an auxiliary support is provided in the work dolly, the auxiliary support being brought into contact with the auxiliary support surface further on the inner peripheral side of the elliptical movement path than the plurality of moving portions and supporting a weight of the work board.

2. The assembly work conveyor device according to claim 1, wherein the auxiliary support extends perpendicularly downward from the work dolly in a position further on the inner peripheral side of the elliptical movement path than the plurality of moving portions so as to be brought into contact with the auxiliary support surface.

3. The assembly work conveyor device according to claim 1, wherein the auxiliary support surface is provided in at least a curved portion of the elliptical movement path.

4. The assembly work conveyor device according to claim 3, wherein

a horizontal guide is provided in a linear portion of the elliptical movement path, and

a horizontal auxiliary guide is provided in the work dolly, the horizontal auxiliary guide extending to the inner peripheral side of the elliptical movement path and being movably brought into contact with the horizontal guide.

5. The assembly work conveyor device according to claim 1, wherein

the auxiliary support surface is provided in a portion of the elliptical movement path, and

a guide surface obliquely downward to an exterior is provided in the auxiliary support surface in an end portion on a side where the auxiliary support starts to be brought into contact.

6. The assembly work conveyor device according to claim 1, wherein a support frame stands within the elliptical movement path, the support frame standing alone on one support pillar from a longitudinal view of the elliptical movement path.

7. The assembly work conveyor device according to claim 1, further comprising:

a self-standing auxiliary leg provided in the moving dolly, the self-standing auxiliary leg extending to a side where the work board extends and configured to be provided in a condition contacting the movement surface.
