Deploy. According to the component mounting machine 1, it is possible to prevent the component P arranged on the tray from bouncing when the tray is transferred from the tray mounting unit to the component supply position during normal operation.
  • the control device 100 when performing the recovery operation, makes the conveying speed of the conveying belt 53 by the belt driving device 54 slower than that during the normal operation. Therefore, in the recovery operation, when the tray is transferred from the tray placing unit to the component supply position, it is possible to prevent the components P arranged on the tray from jumping. Further, the control device 100 reduces the transport speed of the transport belt 53 as a recovery operation when the supply tray Tp is not transported to the component supply position within a predetermined time. Therefore, compared with the case where the conveyance speed of the conveyance belt 53 during the normal operation is set to the same speed (low speed) as the recovery operation, the time required for conveying the supply tray Tp to the component supply position during the normal operation is reduced. Shortening can be achieved.
  • the component mounting machine 1 described above includes a first sensor 57 that detects that the tray has been transported from the tray mounting unit to the component supply position.
  • the control device 100 recovers when the first sensor 57 does not detect that the tray has been transported to the component supply position within a predetermined time after the transport from the tray placement unit to the component supply position. Perform the action.
  • the control device 100 can determine whether or not the tray has been transported to the component supply position. If the tray has not been transported to the component supply position within a predetermined time, recovery can be performed. Perform the action. Therefore, the component mounting machine 1 can efficiently carry the tray.
  • control device 100 performs the recovery operation when the empty tray Te as the tray is not conveyed from the component supply position to the empty tray holding unit 39 as the tray placing unit in the normal operation.
  • the relative height position of the upper surface of the conveyor belt 53 with respect to the upper surface of the empty tray holding unit 39 as the tray mounting unit is set higher than that in the normal operation.
  • the control device 100 when the tray is not transported from the component supply position to the tray mounting unit, the control device 100 performs a recovery operation so that the tray is transferred from the component supply position to the tray mounting unit. Transport is prompted. Therefore, the component mounting machine 1 can efficiently carry the tray.
  • the component mounting machine 1 described above includes a second sensor 58 that detects that the tray has been transported from the component supply position to the tray placement unit.
  • the control device 100 recovers when the second sensor does not detect that the tray has been transported to the tray mounting portion within a predetermined time after starting the transport from the component supply position to the tray mounting portion. Perform the action.
  • the control device 100 can determine whether or not the tray has been transported to the tray mounting unit, and when the tray has not been transported to the tray mounting unit within a predetermined time.
