Management device and management method, and work device

A management method for use in a component mounting system including a mounting line on which component mounting machines are arranged each of the component mounting machines including a supply target attachment section having multiple slots to which a feeder is attached, a buffer target attachment section having multiple slots to which the feeder is attached, and a mounting head configured to execute a mounting job of picking up and mounting a component supplied from a feeder attached in a slot in the supply target attachment section, and a work device configured to perform serving work and collecting work of the feeder for each of the component mounting machines on the mounting line including each slot in the supply target attachment section and each slot in the buffer target attachment section,

• the method comprising:
• determining, in a case where a target feeder to be used in a target job to be executed from a next time is pre-served in a target component mounting machine of the component mounting machines configured to execute the target job, a serving destination among empty slots of the target feeder in the supply target attachment section and empty slots in the buffer target attachment section of the target component mounting machine by giving priority to the empty slots in the buffer target attachment section, and causing the work device to pre-serve the target feeder in the determined serving destination of the target component mounting machine;
• and
• when there is no empty slot in either the supply target attachment section or the buffer target attachment section of the target component mounting machine, determining the serving destination to the supply target attachment section or the buffer target attachment section of an other component mounting machine that is different from the target component mounting machine among the component mounting machines, and cause the work device to pre-serve the target feeder in the determined serving destination of the other component mounting machine.

A work device for use in a component mounting system including a mounting line on which component mounting machines are arranged each of the component mounting machines including a supply target attachment section having multiple slots to which a feeder is attached, a buffer target attachment section having multiple slots to which the feeder is attached, and a mounting head configured to execute a mounting job of picking up and mounting a component supplied from a feeder attached in a slot in the supply target attachment section, and configured to perform serving work and collecting work of the feeder for each of the component mounting machines on the mounting line including each slot in the supply target attachment section and each slot in the buffer target attachment section,

• wherein, in a case where a target feeder to be used in a target job to be executed from a next time is pre-served in a target component mounting machine of the component mounting machines configured to execute the target job, among empty slots in the supply target attachment section and empty slots in the buffer target attachment section of the target component mounting machine, the work device pre-serves the target feeder in a serving destination in which the empty slots in the buffer target attachment section of the target component mounting machine are prioritized, and
• when there is no empty slot in either the supply target attachment section or the buffer target attachment section of the target component mounting machine, determine the serving destination to the supply target attachment section or the buffer target attachment section of an other component mounting machine that is different from the target component mounting machine among the component mounting machines, and cause the work device to pre-serve the target feeder in the determined serving destination of the other component mounting machine.
