Binding machine
A binding machine includes a first guide having an introduction part into which the wire to be fed by the wire feeding unit is to be introduced, and configured to curl the wire introduced from the introduction part, a second guide configured to guide the wire delivered from the first guide toward the binding unit, a main body part having one end portion at which the first guide and the second guide are provided, and, an entry regulation part provided in the main body part, provided at one side of the introduction part of the first guide at a downstream side of the binding unit with respect to a feeding direction of the wire to be fed toward the first guide by the wire feeding unit, and configured to prevent the wire from entering into one side of the introduction part of the first guide.
1. A binding machine comprising:
a wire feeding unit configured to feed a wire to be wound on an object to be bound;
a binding unit configured to twist the wire wound on the object to be bound;
a first guide having an introduction part into which the wire to be fed by the wire feeding unit is to be introduced, and configured to curl the wire introduced from the introduction part;
a second guide configured to guide the wire delivered from the first guide toward the binding unit;
a main body part having one end portion at which the first guide and the second guide are provided; and
an entry regulation part provided in the main body part, provided at one side of the introduction part of the first guide at a downstream side of the binding unit with respect to a feeding direction of the wire to be fed toward the first guide by the wire feeding unit, and configured to prevent the wire from entering into one side of the introduction part of the first guide, wherein
the first guide comprises a guide member configured to curl the wire, and a retraction mechanism configured to retract the guide member,
the entry regulation part is provided at a position at which the wire is prevented from entering into a moveable area of the retraction mechanism,
the main body part includes a cutting unit configured to cut the wire wound on the reinforcing bars, and
the entry regulation part is arranged at a downstream side of the cutting unit with respect to the feeding direction of the wire to be fed toward the first guide by the wire feeding unit.
2. The binding machine according to claim 1 , wherein the entry regulation part has a discharge guide part configured to guide the wire in a discharge direction, and wherein the wire contacts the entry regulation part.
3. The binding machine according to claim 2 , wherein the discharge guide includes an inclined surface, and with respect to a wire discharge direction to an outside of the main body part a tip-end side of the inclined surface is inclined in a direction toward the wire feeding unit.
4. The binding machine according to claim 2 , further comprising:
an opening portion provided at a front end of the main body part and between the first guide and the second guide; and
an operation space in which a part of the binding unit operates inside the main body part,
wherein the discharge guide part is a surface extending in a direction from the operation space to the opening portion.
5. A binding machine comprising:
a wire feeding unit configured to feed a wire to be wound on an object to be bound;
a binding unit configured to twist the wire wound on the object to be bound;
a first guide having an introduction part into which the wire to be fed by the wire feeding unit is to be introduced, and configured to curl the wire introduced from the introduction part;
a second guide configured to guide the wire delivered from the first guide toward the binding unit;
a main body part having one end portion at which the first guide and the second guide are provided; and
an entry regulation part provided in the main body part, provided at one side of the introduction part of the first guide at a downstream side of the binding unit with respect to a feeding direction of the wire to be fed toward the first guide by the wire feeding unit, and configured to prevent the wire from entering into one side of the introduction part of the first guide, wherein
the first guide comprises a guide member configured to curl the wire, and a retraction mechanism configured to retract the guide member,
the entry regulation part is provided at a position at which the wire is prevented from entering into a moveable area of the retraction mechanism, and
the entry regulation part is a convex part protruding toward the retraction mechanism from a part, which is located at a side of the retraction mechanism, of an inner surface of a housing configuring an exterior package of the main body part.
6. The binding machine according to claim 5 , wherein a height of the convex part is set so as not to be in contact with the retraction mechanism when the retraction mechanism is retracted toward the entry regulation part.
