Abstract

A gathering operation includes a restraint operation of moving forward a left lower tool retention member so as to restrain a reference lower tool with the left lower tool retention member, an inserting operation of moving forward a right lower tool retention member so as to insert the right lower tool retention member into an insertion hole of a target lower tool, and an execution operation of moving the left and right lower tool retention members along a left-right direction so as to come close with each other. If a failure of the inserting operation is determined, a control device performs a retry operation of moving forward the right lower tool retention member again so as to insert the right lower tool retention member into the insertion hole (141) of the target lower tool after moving backward the left lower tool retention member.

Claims13

Dependent claims

A bending system comprising:

a press brake in which a plurality of tools is arranged along a left-right direction in a tool holder provided to a table;
a first moving body including a first tool retention member and a second moving body including a second tool retention member capable of being inserted into and removed from an insertion hole provided to a target tool of the plurality of tools 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 plurality of tools, wherein
the gathering operation includes:
a restraint operation of moving forward the 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 the second tool retention member of the second moving body so as to insert the second tool retention member into the insertion hole of the 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 tools of the plurality of tools, including the reference tool and the target tool, are gathered, and
a retry operation, performed by the control device when a failure of the inserting operation is determined, of moving the second tool retention member forward to insert the second tool retention member into the insertion hole of the target tool after moving the first tool retention member backward to release the restraint operation of the reference tool.

A method of arranging tools in a press brake, comprising:

providing a press brake including a plurality of tools, a first moving body having a first tool retention member, a second moving body having a second tool retention member, wherein the first moving body and the second moving body are provided to a rear surface side or a front surface side of a table of the press brake,
controlling, using a control device, movement of the first moving body and the second moving body in a left-right direction to arrange the plurality of tools along the left-right direction in a tool holder provided to the table, wherein
performing, using the control device, a gathering operation of gathering the plurality of tools so that there are no gaps between the plurality of tools arranged in the tool holder;
wherein
the gathering operation includes:
a restraint operation of moving the first tool retention member of the first moving body forward along a front-back direction so as to restrain a reference tool of the plurality of tools positioned at one end of the plurality of tools with the first tool retention member;
an inserting operation of moving the second tool retention member of the second moving body forward along the front-back direction so as to insert the second tool retention member into an insertion hole of a target tool selected from among remaining tools of the plurality of tools, which exclude the reference tool;
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 tools of the plurality of tools, from the reference tool to the target tool, are gathered, and
a retry operation, performed by the control device when a failure of the inserting operation is determined, of moving the second tool retention member forward to insert the second tool retention member into the insertion hole of the target tool after moving the first tool retention member backward to release the restraint operation.
