Binding machine

A binding machine comprising:

• a wire feeding unit configured to feed a wire;
• a curl guide arranged along a loop feeding path of the wire along which the wire fed in a first direction by the wire feeding unit is wound around an object;
• and
• a binding unit which includes a rotating shaft to twist the wire fed in the first direction by the wire feeding unit and wound on the object,
• wherein the wire feeding unit comprises a pair of feeding members and a feeding motor that drives the feeding members, the pair of feeding members having a cylindrical outer surfaces, being arranged such that the outer surfaces face each other with a feeding path of the wire being interposed therebetween, and being configured to rotate in mutually opposite directions so as to feed the wire sandwiched between the outer surfaces,
• wherein the binding machine further comprises a control circuit configured to control the wire feeding unit, and a sensor that detects movement due to rotation of the feeding members, and
• wherein the control circuit is configured to automatically rotate the feeding motor in a rotating direction in which the wire is fed in the first direction when the sensor detects movement due to the rotation of the feeding members in a state where the feeding motor is non-energized.

A binding machine comprising:

• a wire feeding unit configured to feed a wire;
• a curl guide arranged along a loop feeding path of the wire along which the wire fed in a first direction by the wire feeding unit is wound around an object;
• a cutter that cuts the wire wound around the object;
• and
• a binding unit which includes a rotating shaft to twist the wire fed in the first direction by the wire feeding unit and wound on the object,
• wherein the wire feeding unit comprises a pair of feeding members and a feeding motor that drives the feeding members, the pair of feeding members each having cylindrical outer surfaces, being arranged such that the outer surfaces face each other with a feeding path of the wire being interposed therebetween, and being configured to rotate in mutually opposite directions so as to feed the wire sandwiched between the outer surfaces,
• wherein the cutter is provided on the feeding path between the wire feeding unit and the binding unit and cut the wire to divide the wire into a part on a side near to the binding unit from the cutter and another part on a side near to the feeding unit from the cutter,
• wherein the binding machine further comprises a control circuit configured to control the wire feeding unit and the cutter,
• wherein the control circuit is configured to control the wire feeding unit to enable the another part of the wire cut by the cutter and sandwiched by the feeding members to be discharged from the feeding members,
• wherein the pair of feeding members has one feeding member and the other feeding member, at least the one feeding member being displaceable toward and away from the other feeding member,
• wherein the wire feeding unit comprises:
• an actuator that displaces at least the one feeding member, and
• wherein the control circuit is configured to control the actuator to displace one or both of the one feeding member and the other feeding member away from each other, thereby enabling the wire sandwiched by the one feeding member and the other feeding member to be discharged from between the one feeding member and the other feeding member.
