Bending system, and divided tool arrangement method

A bending system comprising:

• a press brake in which a plurality of tools are arranged along a left-right direction in a tool holder provided to a table;
• a first moving body and a second moving body each including a tool retention member capable of being inserted into and removed from an insertion hole provided to the tool by moving forward and moving backward along a front-back direction, and provided on a rear surface side or a front surface side of the table so as to be movable in the left-right direction;
• and
• a control device configured to control each of the first and second moving bodies so as to perform a gathering operation of gathering the plurality of tools so that there are no gaps between the tools, wherein
• the gathering operation includes:
• a restraint operation of moving forward a first tool retention member of the first moving body so as to restrain a reference tool positioned at one end of the plurality of tools with the first tool retention member;
• an inserting operation of moving forward a second tool retention member of the second moving body so as to insert the second tool retention member into the insertion hole of a target tool selected from among remaining tools, which exclude the reference tool, of the plurality of tools;
• and
• an execution operation of moving the first and second moving bodies along the left-right direction so as to come close to each other so that the tools from the reference tool to the target tool are gathered, and
• the control device performs, when a failure of the inserting operation is determined, a retry operation of moving forward the second tool retention member again to insert the second tool retention member into the insertion hole of the target tool after moving backward the first tool retention member to release the restraint operation.
