2. Description of the Related Art Conventionally, a work is directly placed on an automated guided vehicle to be carried on a work line, and work such as assembling, assembling and disassembling the work has been carried out in each process provided on the work line. That is, in the past, the automatic guided vehicle and the workbench were not separated, and the work was performed on the automatic guided vehicle regardless of the length of the working time in each work process.

Conventionally, however, when a certain work process is longer than the total production cycle time (tact time), a plurality of stations must be provided in the work process, but in this case, one work line is used. Therefore, there is a problem that the same number of automated guided vehicles as the plurality of stations are occupied in the working process, and a large number of automated guided vehicles are required. In addition, since the number of work lines is one, it is necessary to produce different models on the same line when performing simultaneous multi-model production.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the embodiments shown in the accompanying drawings. FIG. 1 shows a line configuration diagram of an embodiment of the present invention. In the line of FIG. 1, when the total production cycle time (tact time) is set to 100 seconds, the work time is 80 seconds for step 1, 90 seconds for step 2, and 100 hours for step 4. Seconds, so
Since the condition “working time in each process ≦ total production cycle time” is satisfied, the number of stations in each process may be one. However, in step 3,
Since the working time is 500 seconds, the number of stations must be 5 in order to satisfy the condition "working time in each process ≤ total production cycle time". Here, if the work 2 is directly placed on the automatic transport vehicle 3 and transported as in the conventional case, the number of the automated transport vehicles 3 in each of the steps 1, 2, and 4 may be one, but the step 3 Since only five stations have five stations, five automated guided vehicles 3 are required. Therefore, the present invention is characterized in that the automated guided vehicle 3 and the workbench 1 are freely connectable, separated in a process in which the work time is long, and connected in a process in which the work time is short.

More specifically, in the embodiment shown in FIG. 1, a detour route 22 is formed in addition to the step 3 on the way from the step 2 to the step 4 of the line, and the automatic guided vehicle 3 has the step 2.
