Claim of US Patent No. 10,091,920

1. A board work device comprising:a conveyance section that conveys boards on which multiple board works are performed, the conveyance section including a first lane and a second lane in which the boards are conveyed;
a work section that performs the board works on the board, the work section including a head holding body that exchangeably holds multiple types of heads, the head holding body only holding one head at a time depending on the board work to be performed;
a moving device which moves the head holding body; and
a controller configured to
acquire a corresponding relationship between the types of heads and each of the multiple board works to be performed for each of the boards;
acquire a priority order between at least two of the board works from the multiple board works within the same board;
set one of the first lane and the second lane as a work lane; and
control the work section and the moving device,
wherein, when performing the board work based on the acquired corresponding relationship, in a case in which there is no board work capable of being performed on the board being conveyed in the work lane using the head currently being held by the head holding body while maintaining the priority order, and there is board work capable of being performed on the board being conveyed in the other lane using the head currently being held by the head holding body while maintaining the priority order, the controller is configured to set the other one of the first lane and the second lane as the work lane and perform the board work in the updated work lane without exchanging the head currently being held, and
wherein the board work is only performed in the work lane.
