PURPOSE: To reduce the time of processing and save a space for keeping by enabling devices whose processing times are different, to be incorporated into a line through the use of a carrying in, keeping, carrying out device.
CONSTITUTION: A carrying in, keeping, carrying out device 5 which is able to carry in a material out of a material supplier at a plate material processing line and keep it and conduct the carrying out of a component in a state in which a processor A2 and other devices downward are able to do processing, is provided, and the materials in the necessary processing number of plates are carried in and kept by means of this device 5 during the operation of the plate material processing line, and the materials are supplied from this device 5 to a pre-process processor 6 which is for processing a pre-process necessary for processing requiring a long time. After the completion of this pre-process processing, these materials are supplied to a processor D7 and processing is completed at this device and then, transport is made to this carrying in, keeping, carrying out device 5. Such an action is repeated as many as the necessary processing number of plates, and carrying out is made at a timepoint when the plate material processing line has come to the state of being able to process the component kept at this device 5.
