Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for temporarily attaching a molded ceiling for an automobile when the molded ceiling for the automobile is mounted on a vehicle body roof panel in an automobile assembly line.

[0002]

2. Description of the Related Art Conventionally, in a car assembly line, a molded ceiling is mounted by a worker carrying the molded ceiling into a vehicle compartment through an opening in a front window (or a rear window), and then lifting it to a roof panel of a vehicle body. While pressing it, it was aligned to the regular position, and its peripheral edge was attached to the vehicle body roof panel with connecting parts such as clips. However, it is a particularly difficult task because it is a large part, it is a work to attach from bottom to top, and even if it is a part that is easily damaged, conversely, if it is damaged or soiled even a little, the product strength will be lost. And usually two people go as a group. Therefore, various methods have been proposed in order to rationalize this work, and all of the work of mounting the molded ceiling, that is, taking out the molded ceiling stored in a pallet, etc., carried it into the vehicle body, and put it in place. There is also proposed a method of automatically holding and fixing by a robot while using an industrial camera or a position sensor (see Japanese Patent Laid-Open No. 3-292276). However, in some cases, it may not be possible to automate all by a robot due to the shape of the vehicle body or the like.
The one disclosed in Japanese Patent No. 53 is an automated one up to the point where the molded ceiling is carried in and held in the vehicle compartment.

[0003]

The object of the present invention is the latter of the above, that is, the case where all the mounting work of the molded ceiling cannot be automatically performed by the robot. By the way, in Japanese Patent Laid-Open No. 63-48753, since the molding ceiling is automated to the place where it is carried in and held in the passenger compartment, it is difficult for workers to move large parts or hold them from bottom to top. In terms of openness, it greatly contributes to work improvement and rationalization. However, the worker does the next task, namely
The holding device remains in the vehicle compartment even when the positioning is performed and the molded ceiling is attached to the vehicle body roof panel with a clip or the like. Therefore, the holding device interferes with the work in the limited space inside the vehicle compartment, and interferes with the clip striking work and the movement. In addition, while the holding device is temporarily stopped during the work, the worker puts himself within the operating range, which is unsafe. Furthermore, such an attachment work is a cooperative work with the device, and the worker needs to move in accordance with the device in order to finish the work in the process, forcing the worker to increase the burden in that respect. As a result, work efficiency is reduced.

[0004]
