A hemming device includes an anvil for placing a work, a presser material handling portion, a conveyance robot, and a roller hemming robot. The anvil includes an anvil main body portion, a positioning device, a gripping device, and a device-side ATC device to be attached to and detached from a conveyance-robot side ATC device. The presser material handling portion includes a frame portion having a shape corresponding to a shape of the work, a positioning device, a gripping device, a presser provided to press the inner panel at a position at which the presser does not interfere with a final shape, and a device-side ATC device to be attached to and detached from the conveyance-robot side ATC device. With this configuration, processing time is reduced and replacement operation of the anvil is simplified, and therefore productivity is improved.

Hemming device and hemming method

Plural wok pairs composed of a plurality of works are stored in work storing means. A movable sensorfitted to a conveyance robotdetects the position of one of the work pairs in the work storing means, and the work gripping meanstakes out a plurality of works at one time from the work storing means. One of the plurality of works is held temporally by temporal work holding meansorwhile the other work is conveyed to a jig Y. In the course of conveyance, a fixed sensordetects the relative positional relationship between the work and the work gripping means. If the relative positional relationship deviates from the regular positional relationship, the movement of a robot armis corrected.
