Abstract
On a back side of a table, moving bodies are provided being movable in a left-right direction. A bending system includes moving actuators to cause the moving bodies to move in the left-right direction relative to the table and position detectors to detect positions of the moving bodies in the left-right direction. The moving bodies are provided with hole detectors to detect the engagement holes of tools fitted to a tool holder. The bending system includes a hole position acquisition unit to acquire positions of the engagement holes of the tools in the left-right direction, based on positions of the moving bodies in the left-right direction at the time of the engagement holes of the tools being detected.
Claims6
A bending system comprising:
- a press brake including a table and a tool holder provided on the table, a plurality of tools being fitted to the tool holder;
- a tool changer provided on a back side or a front side of a table of the press brake so as to be movable in a left-right direction via a guide extending in the left-right direction;
- a moving actuator configured to cause the tool changer to move in the left-right direction relative to the table;
- a position detector configured to detect a position of the tool changer in the left-right direction;
- a hole detector configured to detect an engagement hole for causing a hook of the tool changer to be engaged and disengaged, the engagement hole being a part of a tool of the plurality of tools fitted to the tool holder provided on the table;
- and
- a control device including a memory and a CPU, wherein the CPU is configured to acquire a position of the engagement hole of the tool in the left-right direction, based on the position of the tool changer in the left-right direction at the time of the engagement hole of the tool being detected, wherein
- the hole detector is a photoelectric sensor that is provided on the tool changer, and the hole detector and the engagement hole of the tool are located at a same height as one another when the tool is fitted to the tool holder provided on the table, and
- the hole detector is configured, during a movement of the tool changer in the left-right direction, to emit an inspection beam to the engagement hole of the tool and to detect the engagement hole of the tool from a result of receiving a reflected beam of the inspection beam.
