Binding machine
A binding machine comprises a cutting portion which cuts the wire, a fixed blade in which a first wire passage through which the wire passes is formed; and a movable blade in which a second wire passage through which the wire passes is formed. The movable blade includes a blade portion provided on one side of the second wire passage and a passage forming member provided on the other side of the second wire passage, the second wire passage includes a guiding portion for guiding the wire after cutting in a movement when the movable blade moves from the movement finish position to the standby position, and the guiding portion is protrudes in a direction of the guide portion and blocks a portion between the movable blade and the guide portion in a non-wire-passing-through manner when the movable blade moves to the standby position.
1. A binding machine, comprising:
a wire feeding portion which feeds a wire;
a cutting portion which is provided on a downstream side of the wire feeding portion along a feeding direction of the wire fed by the wire feeding portion and cuts the wire; and
a guide portion which is provided on a downstream side of the cutting portion along the feeding direction of the wire and causes the wire to curl by regulating an advancing direction of the wire,
wherein the cutting portion includes:
a fixed blade in which a first wire passage through which the wire passes is formed;
a movable blade in which a second wire passage through which the wire passes is formed and which slides on an outer peripheral surface of the fixed blade and cuts the wire;
a driving member which is connected to the movable blade and drives the movable blade;
a driving portion which drives the driving member; and
a controller which controls the driving portion,
wherein the movable blade is driven by the driving member between a standby position where the first wire passage and the second wire passage communicate with each other and a movement finish position where the first wire passage and the second wire passage do not communicate with each other by sliding on the outer peripheral surface of the fixed blade, and
the controller is configured to control the driving portion, during a single binding operation, to move the driving member to cause the movable blade to move:
from the standby position to the movement finish position in a wire cutting direction to cut the wire, then
from the movement finish position to the standby position in a reverse direction that is opposite of the wire cutting direction, then
from the standby position towards the movement finish position by a predetermined amount in the wire cutting direction
return back to the standby position.
