Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automobile body processing system.

The assembly of a car body is carried out by spot welding both sides of the car body as well as the front and rear parts. Conventionally, while the car body is being transported in the longitudinal direction on a vertical conveyor, automatic spot welding equipment is used to spot weld both sides of the car body, and the spot welding on the front and rear parts of the car body is transferred to another conveyor. Instead, the car body was turned 90 degrees, and the front and rear sides of the car body along the transport direction were spot welded using automatic spot welding equipment. Therefore, spot welding on both sides of the vehicle body, as well as on the front and rear parts, is not performed continuously, making it difficult to improve work efficiency.

The present invention automatically spot-welds the front and rear parts of the car body by changing only the transport direction without changing the orientation of the car body after spot welding both sides of the car body, and then automatically spot welding the front and rear parts of the car body while the car body is being transferred to the conveyor for the next process. , it is possible to continuously spot weld both sides as well as the front and rear parts, thereby providing a highly efficient processing system with no waste.

Embodiments of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a vertical conveyor for transporting the vehicle body W in the longitudinal direction, and automatic spot welding equipment 2 for spot welding both sides of the vehicle body W is installed on both sides of the conveyor. 3 is the vertical conveyor 1
This is a conveyor line for the next process, which is installed parallel to the conveyor line, and has a conveyor truck 4.

In the present invention, a transverse conveyor 5 for laterally transporting vehicle bodies W is installed between the terminal end of the vertical conveyor 1 and the transport conveyor line 3, and the vehicle bodies W are disposed on both sides of the transverse conveyor 5 along the transport direction. Automatic spot welding device 6 for spot welding the front and rear parts of
Set up. Further, between the terminal end of the vertical conveyor 1 and the start end of the horizontal conveyor 5, a roller conveyor 7 for transferring the vehicle body W and a push-out device 8 for the vehicle body W are provided.
A lifter 9 for raising the vehicle body W is installed at the end of the traverse conveyor 5. Further, a hanger 10 that travels on the ceiling is provided directly above the lifter 9, and the vehicle body W raised by the lifter 9 is suspended and carried onto the transport carriage 4 of the transport conveyor line 3.

Since the present invention is as described above, the vehicle body W transported in the longitudinal direction by the vertical conveyor 1
During the transportation process, both sides of the vehicle body W are spot welded by the automatic spot welding device 2. The vehicle body W with both sides spot welded is transferred from the end of the vertical conveyor 1 to the starting end of the horizontal conveyor 5 by the roller conveyor 7 and extrusion device 8, and the vehicle body W is transferred in a horizontal manner. During this transverse transfer process, the automatic spot welding device 6
The front and rear parts of the transverse conveyor 5 are spot welded.
is transferred to the end of the

At the end of the transverse conveyor 5, the vehicle body W is raised by the lifter 9, and the vehicle body W on the lifter 9 is grasped and suspended by the hanger 10 waiting just above it, and the vehicle body W is lifted on the conveyor line 3. The vehicle body W is transported onto a trolley 4 and transported to the next process by the transport vehicle 4.

As described above, according to the present invention, during the process of being transported by the vertical conveyor, the car body whose both sides are spot welded is subsequently transported horizontally, and the front and rear parts are spot welded during the process of horizontal transport, and then the car body is moved to the transport conveyor. Since the parts are transported to the next process by a conveyor, spot welding of both sides of the car body and the front and rear parts can be performed continuously without changing the direction of the car body, and the parts are immediately transferred to the next process by a conveyor. Therefore, spot welding work can be performed extremely efficiently.
