A binding machine includes a curl guide configured to guide a wire in a loop shape around a binding target and a twisting part configured to bind the binding target by twisting the wire guided in the loop shape around the binding target. The curl guide has a tapered protrusion at a tip end-side.

A rebar tying tool may include a twisting mechanism, a body, a grip, and a control board. The twisting mechanism may include a twisting motor and a holder configured to twist a wire around rebus by operation of the twisting motor. The body may house the twisting mechanism. The grip may be disposed below the body and configured to be gripped by an operator. The control board may be configured to control the operation of the twisting motor. The control board may be disposed below a connection between the grip and the body.

A binding machine includes a feeding unit configured to feed a wire and pull back the wire after winding the wire around an object to be bound, a binding unit configured to grip and twist the wire wound around the object with the feeding unit, a motor configured to rotatively drive the feeding unit, and a binding machine main body configured to accommodate therein the binding unit and the motor. The motor is arranged such that at least a part of the motor overlaps the binding unit, as seen from a side of the binding machine main body.

A telescoping extendable boom and a foldable telescoping extendable boom for transporting an item, are disclosed. The foldable telescoping extendable boom having tubular elements (12) and (14) and (15, 17, 18, 19) and (20) each arranged with a longitudinally extending track (25, 29) inside the tubular element. Each longitudinally extending track (25, 29) supports a single shuttle (26) and (30) respectively, internally inside its tubular element (17) and (15), respectively, for movement therealong. Each shuttle (26) and (30) is equipped with a clamp (27) and (30) to selectively clamp the item (298). The longitudinally extending tracks (25, 29) of immediately connecting telescoping tubular elements (17) and (15) are located opposite each other. The inner tubular elements inside said telescoping extendable boom are arranged at their near ends to allow their shuttles to access shuttles of outer tubular elements to enable the clamps (27) and (31) thereof to transfer a said item (298) therebetween.

An apparatus or system for reinforcement bar (rebar) joint recognition using artificial intelligence vision includes a rebar tying tool attached to a micro manipulator; and a macro manipulator for moving the position of the micro manipulator; wherein the macro manipulator is adapted to move the micro manipulator on a first plane; the micro manipulator is adapted to move the rebar tying tool on a second plane parallel to the first plane and at a first axis vertical to the second plane.

A binding machine includes a curl guide configured to guide a wire in a loop shape around a binding target and a twisting part configured to bind the binding target by twisting the wire guided in the loop shape around the binding target. The curl guide has a tapered protrusion at a tip end-side.

It provides a reinforcing bar binding machine capable of surely wrapping and binding a wire to a binding object. The reinforcing bar binding machine (1A) includes a magazine (2A) in which two wires (W) are housed so as to be drawable, a curl guide unit (5A) which winds the arranged wires (W) around the reinforcing bar (S), by the operation of feeding the parallel wires (W) at the curl guide unit (5A) to wind around the reinforcing bar (S), a wire feeding unit (3A) which to wrap around the reinforcing bar (S) with the wires (W) wound around the reinforcing bar (S), and a binding unit (7A) which twists a intersecting portion between one end side and the other end side of the wire (W) wound around the reinforcing bar (S).

A rebar tying tool configured to tie plural rebars using a wire is disclosed herein. The rebar tying tool may include a reel supporting mechanism configured to switch between a first state of detachably supporting a reel on which the wire is wound and a second state of undetachably supporting the reel; a wire feeding mechanism configured to feed the wire from the reel; and an openable cover that at least partially covers at least one of the reel supporting mechanism and the wire feeding mechanism. The reel supporting mechanism may switch from the first state to the second state by a user operation of closing the cover, and/or may switch from the second state to the first state by a user operation of opening the cover.
