Abstract
A binding machine for reinforcing bars comprising a binding machine body, a bending guide arm, a feed adjustment mechanism, and a twisting mechanism. The bending guide arm is arranged at an end of the binding machine body. A binding wire is sent outside reinforcing bars from the bending guide arm and is formed into a loop, and then a portion of the loop is twisted by the twisting mechanism so as to bind the reinforcing bars. The feed adjustment mechanism adjusts a feed of the binding wire according to one of a diameter of the reinforcing bars and a diameter of the loop of the binding wire wound round the reinforcing bars.

A binding machine for reinforcing bars in which a binding wire is sent outside the reinforcing bars from a bending guide arm arranged at an end of a binding machine body so that the binding wire can be formed into a loop and then a portion of the loop is twisted so as to bind the reinforcing bars, said binding machine comprising a discriminating mechanism for discriminating the diameter of the reinforcing bars arranged at an end of the binding machine body, wherein a feed and a binding force of the wire is controlled according to a result of discrimination conducted by the discriminating mechanism.
A binding machine for reinforcing bars, comprising:
- a binding machine body;
- a bending guide arm arranged at an end of said binding machine body;
- a feed gear;
- a feed adjustment mechanism;
- and
- a twisting mechanism,
- wherein a binding wire is sent outside reinforcing bars from said bending guide arm and is formed into a loop, and then a portion of the loop is twisted by said twisting mechanism so as to bind the reinforcing bars, and
- wherein said feed adjustment mechanism adjusts a feed of the binding wire according to one of a diameter of the reinforcing bars and a diameter of the loop of the binding wire wound around the reinforcing bars by disengaging said feed gear from said binding wire.
A binding machine for reinforcing bars, comprising:
- a binding machine body;
- a bending guide arm arranged at an end of said binding machine body;
- a feed adjustment mechanism including:
- a motor,
- a first feed gear rotated by said motor,
- a second freed gear engageable with said first feed gear,
- a link connected to said second feed gear,
- an electromagnet;
- and
- a twisting mechanism,
- wherein a binding wire is sent outside reinforcing bars from said bending guide arm and is formed into a loop, and then a portion of the loop is twisted by said twisting mechanism so as to bind the reinforcing bars,
- wherein said feed adjustment mechanism adjusts a feed of the binding wire according to one of a diameter of the reinforcing bars and a diameter of the loop of the binding wire wound around the reinforcing bars,
- wherein said second feed gear is engaged with said first feed gear in order to feed the binding wire when said electromagnet is not electrified, and
- wherein said second feed gear is attracted by said electromagnet via said link and disengaged with said first feed gear in order to stop feeding the binding wire when said electromagnet is electrified.
A binding machine for reinforcing bars, comprising:
- a binding machine body;
- a bending guide arm arranged at an end of said binding machine body;
- a feed adjustment mechanism;
- and
- a twisting mechanism,
- wherein a binding wire is sent outside reinforcing bars from said bending guide arm and is formed into a loop, and then a portion of the loop is twisted by said twisting mechanism so as to bind the reinforcing bars,
- wherein said feed adjustment mechanism adjusts a feed of the binding wire according to one of a diameter of the reinforcing bars and a diameter of the loop of the binding wire wound around the reinforcing bars, and
- a discriminating mechanism discriminating the diameter of the reinforcing bars,
- wherein a feed and a binding force of the binding wire is controlled according to the diameter discriminated by said discriminating mechanism.
A binding machine for reinforcing bars, comprising:
- a binding machine body;
- a bending guide arm arranged at an end of said binding machine body;
- a feed adjustment mechanism;
- and
- a twisting mechanism,
- wherein a binding wire is sent outside reinforcing bars from said bending guide arm and is formed into a loop, and then a portion of the loop is twisted by said twisting mechanism so as to bind the reinforcing bars,
- wherein said feed adjustment mechanism adjusts a feed of the binding wire according to one of a diameter of the reinforcing bars and a diameter of the loop of the binding wire wound around the reinforcing bars, and
- an auxiliary arm opposite to said binding guide arm;
- two optical sensors respectively attached to said bending guide arm and said auxiliary arm, one of said optical sensors being a light emitting element and the other of said optical sensors being a light receiving element,
- wherein the diameter of the reinforcing bar is detected by a quantity of light detected by the light receiving element, the light being emitted from the light emitting element.
