Abstract: A rebar tying tool may be configured to tie rebars with a wire. The rebar tying tool may include: a feeding unit configured to feed the wire; a guiding unit configured to guide the wire around the rebars; and a grasping unit configured to grasp the wire around the rebars. The grasping unit may include a wire tip guiding surface configured to contact a tip of the wire when the wire is guided around the rebars by the guiding unit. The wire tip guiding surface may be configured to guide the tip of the wire in a direction approaching the rebars when the wire tip guiding surface is in contact with the tip of the wire.

Abstract: A rebar tying machine may be configured to perform: a winding process in which a wire is fed around rebars, a vicinity of a distal end of the wire is grasped, the wire is pulled back, and the wire is cut; and a twisting process in which the wire is twisted. When instructed to tie the rebars by a user, the rebar tying machine may be configured capable of performing a multiple-winding tying operation in which the twisting process is performed. after the winding process has been performed multiple times.

Abstract: A rebar tying tool may include: a screw shaft configured to rotate; a sleeve through which the screw shaft is inserted, and configured to move in a front-rear direction and rotate; a fin member attached to the sleeve and configured to permit and prohibit rotation of the sleeve; a push member attached to the sleeve and configured to rotate about the sleeve, wherein the push member does not rotate along with the rotation of the sleeve; an operated unit having a longitudinal direction in the front-rear direction and configured to be operated by the push member when the sleeve moves in the front-rear direction; and a grasping unit protruding from a front part of the sleeve, configured to rotate with the sleeve, and configured to grasp the wire. The push member may be disposed on a front side relative to the fin member.

Abstract: The disclosure herein discloses a rebar tying machine. The rebar tying machine may include a feed motor, a current sensor configured to detect a current flowing through the feed motor, and a control unit configured to control an operation of the feed motor. The rebar tying machine may be configured to perform: a feeding-out process in which a wire is fed out around rebars by driving the feed motor, a gripping process in which a vicinity of a tip of the wire is gripped, a pulling-back process in which the wire is pulled back by driving the feed motor, a cutting process in which the wire is cut, and a twisting process in which the wire is twisted. The control unit may be configured to determine a diameter of the rebars based on a history of a current value flowing through the feed motor in the pulling-back process.

Abstract: A rebar tying tool ties together two or more rebars using a wire. The rebar tying tool may include: a reel comprising the wire wound on a bobbin; a reel-holding part configured to hold the reel in a rotatable manner; a feed part configured to advance the wire from the reel by a number of turns of the wire around the rebars; and a twisting part configured to twist the wire after the number of turns of the wire has been wound around the rebars. The wire preferably has a maximum tensile load of at least 700 N. Preferably, the wire after the number of turns of the wire has been wound around the rebars has an overall maximum tensile load of at least 1,050 N, which is calculated by multiplying the maximum tensile load of the wire by the number of turns of the wire around the rebars.

Abstract: A rebar tying tool may include a holder, a stopper, a driving roller, and a driven roller. The stopper may be configured to switch between a prohibiting state in which the stopper prohibits a reel from detaching from the holder and an allowing state in which the stopper allows the reel to detach from the holder. The driving roller may be configured to rotate. The driven roller may be configured to switch between a clamped state and a non-clamped state, the wire may be clamped between the driving roller and the driven roller when the driven roller is in the clamped state, and the wire may not be clamped between the driving roller and the driven roller when the driven roller is in the non-clamped state. The driven roller may be in the non-clamped state at all times while the stopper is in the allowing state.
