Description

  The present invention relates to a door panel transfer device, and more particularly, to a door panel transfer device used for a part assembly line of an automobile door panel.

  In general, in a part assembly line for an automobile door panel, the door panel unloaded from the accumulation line is sequentially transported to each assembly process by a door panel transport device. An example of such a door panel transfer device is described in Patent Document 1. The door panel transport device includes a hanger formed in a frame shape, and among the front and rear columns (columns on both front and rear sides of the door panel to be transported) constituting the hanger, one column has a fixed support member and the other A movable support member is provided on the column. In the door panel transport device, the movable support member is linearly moved toward the fixed support member, and the front and rear edges of the door panel carried in the interval between the fixed support member and the movable support member are gripped by the respective support members. Therefore, in the conventional door panel transport device, the movable support member only moves linearly toward the fixed support member. Therefore, when the door panel is moved in the front-rear direction of the door panel and carried in, the movable support member is the door panel. Always present in the carry-in route. For this reason, in the conventional door panel conveyance device, the door panel cannot be moved in the front-rear direction of the door panel and carried in, and in order to avoid interference between the door panel and the support member, the fixed support member and the movable support member It is necessary to carry in the door panel from the direction substantially orthogonal to the front-rear direction of the door panel.

As shown in FIG. 6, in the conventional door panel transfer apparatus 1, the door panels 3 are arranged in a vertical row and are transferred through the storage zone 17 of the accumulation line in the front-and-rear direction of the door panel (the front-rear direction in the paper view in FIG. 6). Even so, since the door panel carry-in route of the door panel transport device 1 cannot be set on the same straight line as the door panel carry-out route of the storage zone 17, the door panel 3 is moved in a direction different from the door panel carry-out direction, It is necessary to carry in at a distance from the movable support member. For this reason, in the conventional door panel transfer apparatus 1, it is necessary to interpose a door panel carrying-in apparatus such as a manipulator between the storage zone 17 and the door panel transfer apparatus 1, which increases the equipment cost and increases the storage zone 17 and the door panel. It takes time to deliver the door panel to and from the transfer device, and the production efficiency is lowered. Further, since the door panel carry-out path and the door panel carry-in direction cannot be set on the same straight line, the degree of freedom of the line layout is low and an inefficient line layout is forced.
