Maintenance device

A maintenance device applied to a bulk feeder including

• a feeder main body section,
• a track member that includes a receiving region that is provided in the feeder main body section and receives a supply component which is a part of multiple supply components discharged from a component case in which the supply components are accommodated in a bulk state and supplied to a component mounter, a supply region where the component mounter can collect the supply component, and a conveyance path on which the supply component is conveyed between the receiving region and the supply region,
• a vibration device that is provided in the feeder main body section and vibrates the track member to convey the supply component on the conveyance path between the receiving region and the supply region, and
• a cavity group that is provided in the supply region and includes multiple cavities in which one component of the supply components conveyed from the receiving region to the supply region is to be accommodated,
• the maintenance device comprising:
• an initialization section configured to return the supply component existing in the cavity group toward the receiving region, and set the cavity group to an initialization state in which the supply component does not exist in the cavity group as much as possible every time use time of the bulk feeder elapses a predetermined time;
• and
• a vibration force control section configured to increase a vibration force to be applied to the track member by the vibration device in the initialization section compared with a case of returning the supply component from the supply region toward the receiving region in order to adjust a number of the supply components to be conveyed to the cavity group when a board product is produced.
