Claims (12)

  1. A board work machine comprising: a backup plate having a first placement surface on which a backup member configured to support a board from below is placed; an accommodation section having an opening in the first placement surface, the accommodation section being configured to accommodate the backup member below the first placement surface; and a cover member provided to be openable and closable with respect to the opening of the accommodation section and having a second placement surface on which the backup member is placed in a closed state.
  2. The board work machine according to Claim 1, further comprising: a control device configured to perform arrangement change processing of moving each of multiple of the backup members from a current position to a target position, wherein, in the arrangement change processing, when an opening/closing operation of the cover member is required, the control device moves the backup member from the current position to a temporary placement position set on the first placement surface, and moves the backup member from the temporary placement position to the target position after the opening/closing operation of the cover member.
  3. The board work machine according to Claim 2, wherein when a current number of the backup members before processing is different from a required number of the backup members after processing, the control device determines that the opening/closing operation of the cover member is required to accommodate or take out the backup member.
  4. The board work machine according to Claim 2 or 3, wherein the control device sets the temporary placement position based on the current position and the target position of the backup member that is a movement target.
  5. The board work machine according to Claim 2 or 3, wherein the control device sets the temporary placement position based on a position of another backup member different from the backup member that is a movement target.
  6. The board work machine according to Claim 2 or 3, wherein the control device selects an empty section in which the backup member is not present among multiple sections formed by dividing the first placement surface, and sets a position corresponding to the empty section as the temporary placement position.
  7. The board work machine according to Claim 2 or 3, wherein the control device sets, as the temporary placement position, one candidate in which the backup member is not present among candidates of the temporary placement position set in advance on the first placement surface.
  8. The board work machine according to Claim 2 or 3, wherein in the arrangement change processing, when the opening/closing operation of the cover member is required, and when the current position of the backup member that is a movement target is on the second placement surface, and the target position is inside the accommodation section, the control device moves the backup member to the temporary placement position, sets the cover member to an open state, and then accommodates the backup member in the accommodation section.
  9. The board work machine according to Claim 2 or 3, wherein in the arrangement change processing, when the opening/closing operation of the cover member is required, and when the current position of the backup member that is a movement target is inside the accommodation section and the target position is on the second placement surface, the control device sets the cover member to an open state, moves the backup member to the temporary placement position, sets the cover member to a closed state, and then moves the backup member to the target position.
  10. The board work machine according to Claim 1 or 2, wherein the board work machine is a component mounter including a board conveyance device configured to convey the board to a predetermined position in the component mounter and to position the board by using the backup member, and a mounting head configured to mount a component on the positioned board.
  11. The board work machine according to Claim 10, wherein the mounting head is provided with a picker capable of holding the backup member, and moves the backup member by using the picker.
  12. A method for changing an arrangement of a backup member, the method to be applied to a board work machine configured to perform a predetermined board work on a board, the board work machine including a backup plate having a first placement surface on which the backup member configured to support the board from below is placed, an accommodation section having an opening in the first placement surface, the accommodation section being configured to accommodate the backup member below the first placement surface, a cover member provided to be openable and closable with respect to the opening of the accommodation section and having a second placement surface on which the backup member is placed in a closed state, and a control device configured to perform arrangement change processing of moving each of multiple of the backup members from a current position to a target position, the method comprising: a first step of moving the backup member from the current position to a temporary placement position set on the first placement surface in the arrangement change processing, when an opening/closing operation of the cover member is required; and a second step of moving the backup member from the temporary placement position to the target position after the opening/closing operation of the cover member.

Description

Technical Field The present invention relates to a board work machine and a method for changing an arrangement of a backup member. Background Art A board work machine is used for production of product boards. The board work machine includes a backup device that supports a board from below by a backup member arranged at a predetermined position inside the machine when a predetermined board work is performed. Patent Literature 1 discloses a component mounter that includes a backup device and mounts a component on a board as a board work. The number, type, arrangement position, and the like of a backup member are appropriately set according to a board work scheduled to be performed, the type of board, and a state of a bottom surface (a lower surface of a positioned board) of a board. Citation List Patent Literature Patent Literature 1: WO2004/103054A Summary of the Invention Technical Problem In a board work machine including a backup device, it is desired to increase the degree of freedom in arrangement of a backup member to more reliably support a board.
