Tool, a system and a method for manufacturing of a reinforcement bar structure

A method for transporting and attaching a reinforcement bar during manufacturing of a reinforcement bar structure using a tool comprising a main body, the method comprising

• gripping, by the tool, a reinforcement bar between a first peripheral end section of a first jaw and a second peripheral end section of a second jaw by using a jaw arrangement comprising the first jaw, partly placed in a first side section of the main body, and the second jaw, partly placed in a second side section of the main body, and a mechanical arrangement that moves the jaw arrangement, and
• tying together, by a tying device of the tool, placed in a mid-section of the main body, wherein the mid-section is situated between the first side section and the second side section, the reinforcement bar with another reinforcement bar, together forming a group of reinforcement bars, by
• looping a wire around the group of reinforcement bars while having the first peripheral end section and the second peripheral end section spaced apart,
• tightening the wire around the group of reinforcement bars,
• forming a knot, and
• cutting the wire,
• wherein gripping, by the tool, the reinforcement bar and tying together, by the tying device of the tool, the reinforcement bar with another reinforcement bar are made by using a first robot, and
• wherein tying together, by the tying device of the tool, the reinforcement bar with another reinforcement bar is preceded by
• gripping the reinforcement bar by using a second robot, and
• releasing the reinforcement bar with the first robot.

A tool for manufacturing of a reinforcement bar structure, wherein the tool comprises

• a main body,
• a jaw arrangement comprising a first jaw partly placed in a first side section of the main body and a second jaw partly placed in a second side section of the main body,
• a tying device placed in a mid-section of the main body, wherein the mid-section is situated between the first side section and the second side section,
• characterized in that
• the tool further comprises
• an arrangement configured for moving the jaw arrangement between a gripping state and a tying state,
• wherein, in the gripping state, the first jaw and the second jaw are leaning towards one another such that a reinforcement bar can be held between a first peripheral end section of the first jaw and a second peripheral end section of the second jaw,
• wherein, in the tying state, the first peripheral end section and the second peripheral end section are spaced apart such that a wire can be looped around a group of reinforcement bars placed between the first and second jaw, and
• wherein the tool further comprises a wire guiding arrangement comprising a first guider and a second guider, wherein the first guider is placed next to the first jaw and the second guider is placed next to the second jaw.
