提供することをその目的とする。(Problems to be solved by the invention) In the above method, the line must be stopped when replacing jigs, which poses a problem in terms of productivity improvement. is provided so that it can be freely reversed so that when -1 is in the welding position, the other is in the standby position, and when changing the model, the welding jig for the next machine that is in the standby position is reversed to the welding position and the line is stopped. It is also considered to be possible to replace the jig without changing the welding jig.However, when performing multi-machine welding of three or more types, it is necessary to replace the used welding jig that is turned over to the standby position. It is necessary to replace the welding jig with another welding jig, and in this case, to provide a stockyard for the welding jig on the side of the standby position, a large space for the stockyard in addition to the side panel processing line is required on both sides of the floor processing line. In factories with space constraints, it is necessary to secure a stockyard away from the assembly line, and changing jigs takes time. There is loss time due to jig replacement, and it is difficult to expect much improvement in productivity.In order to solve this problem, the present invention efficiently replaces jigs during line operation without increasing the line side space on both sides of the floor machining line. The object is to provide a device which allows for exchange.
