The group leader arrangement has the contents of 200 boxes of unprocessed material to be made and 200 boxes of material that has already been processed for the first process. First the system will continuously transport 20 non-finished bins from the warehouse for distribution. Each station is provided with a material box for processing, and then 20 material boxes are transported out to a cache area of the station, so that uninterrupted processing of the station is guaranteed. After a material case was processed to No. 1 sewing machine, reach the ejection of compact district after sweeping the sign indicating number on ejection of compact conveying line and through the ejection of compact, after the ejection of compact district accumulated a certain amount, the AGV dolly was pulled away together, increased efficiency. Then the material inlet is supplemented with a material box to flow to a No. 1 sewing machine. After the work station completes the task, the system can be informed of the next operation through a button arranged at the work station. Because of the different proficiency of workers, when the first process of the 2000 bi-needle machine is finished, the captain may schedule the second process to be performed by the production station. After the materials are scheduled, the material boxes grabbed by the AGV from the warehouse are the material boxes which have finished the first procedure, and are issued to the finished stations. When the first process on the production line is completed completely, that is, 2000 pairs of first processes are completed, the production line is completely filled with the materials of the second process. The following steps are analogized. The group leader may schedule and schedule production tasks at will.
