Component mounting system

A component mounting system configured to pick up a component supplied from a component supply device and to mount the component on a target object, the component mounting system comprising:

• multiple suction nozzles, each capable of picking up the component;
• a rotary head configured to hold the multiple suction nozzles in a circumferential direction, and to be capable of revolving each suction nozzle in the circumferential direction around a central axis of the rotary head and simultaneously spinning each suction nozzle around respective nozzle axes;
• a lifting and lowering device configured to lift and lower a suction nozzle at a predetermined revolving position, among the multiple suction nozzles;
• a storage device configured to store directionality information in association with identification information of the suction nozzles, the directionality information defining a nozzle angle of each of the suctions nozzles in which the component is able to be picked up, the directionality information including:
• no directionality in which the component supplied from the component supply device is able to be picked up at any nozzle angle;
• one direction in which the component supplied from the component supply device is able to be picked up only at one specific nozzle angle;
• two directions in which the component supplied from the component supply device is able to be picked up only at any one of two specific nozzle angles;
• and four directions in which the component supplied from the component supply device is able to be picked up only at any one of four specific nozzle angles, and
• a control device configured to acquire the identification information of a suction nozzle of the suction nozzles used in picking up the component, to acquire corresponding directionality information from the storage device based on the acquired identification information, and to control the head and the suction nozzle such that the component supplied from the component supply device is picked up at the nozzle angle in accordance with the acquired directionality information.
