Abstract: A self-propelled robot transfer system and a transfer robot used in the system is provided with which, when a reinforcing bar binding self-propelled robot reaches near the end of a reinforcing bar while moving on the reinforcing bar as a track, an operator can move the self-propelled robot in the opposite direction using another reinforcing bar as a new track without having to lift the self-propelled robot by himself, as a result of which, turnaround working of the self-propelled robot can be easily achieved.

Abstract: A binding wire supply system for a reinforcing bar binding machine for supplying binding wire to a reinforcing bar binding machine from the outside of the reinforcing bar binding machine that binds intersections of reinforcing bars with the binding wire, wherein the binding wire supply system includes a reel mounting unit on which a binding wire supply reel, which is arranged close to the reinforcing bar binding machine and supplies the binding wire to the reinforcing bar binding machine, is mounted; a binding wire adapter for introducing the binding wire supplied from the binding wire supply reel into a binding wire accommodating magazine of the reinforcing bar binding machine; and a binding wire insertion guide into which the binding wire is inserted from the reel mounting unit to guide the binding wire to the binding wire adapter.

Abstract: A self-propelled robot for rebar binding including wheel units that travel on intersecting rebars; frame units mounted multiply aligned on right and left of the wheel units corresponding to an array interval of the rebars on which the wheel unit travels, binder holding units positioned between a front wheel and rear wheel of the wheel unit and by which rebar binders that bind intersecting rebars are detachably mounted per each wheel unit; driving units each having a binder driving portion that drives the binder holding unit up and down; and a control unit that controls travel motion of the wheel units and binding motion of the rebar binder. The driving units each include a trigger driving pin, and the control unit having a binding control portion that causes the trigger driving pins of the driving units to simultaneously and respectively press the triggers of the rebar binders.
