Abstract

binding machine including a wire feeding unit configured to feed a wire, a cutting unit configured to cut the wire wound on an object, a binding unit configured to twist the wire wound on the object and cut by the cutting unit, at least one motor configured to drive one or more of the wire transfer unit, the cutting unit and the binding unit, and a control unit configured to limit a current flowing through the motor, in response to a battery voltage of a battery, in a section in which a large amount of current flows through the motor, as compared with a section in which a small amount of current flows through the motor, while the current flows from the battery to the motor. r unit, the cutting unit and the binding unit, and a control unit configured to limit a current flowing through the motor, in response to a battery voltage of a battery, in a section in which a large amount of current flows through the motor, as compared with a section in which a small amount of current flows through the motor, while the current flows from the battery to the motor.

Claims

1. A binding machine comprising: a wire feeding unit configured to feed a wire; 5 a cutting unit configured to cut the wire wound on an object; a binding unit configured to twist the wire wound on the object and cut by the cutting unit; at least one motor configured to drive one or more of the wire transfer unit, the cutting unit and the binding unit; and 10 a control unit configured to limit a current flowing through the motor, in response to a battery voltage of a battery, in a section in which a large amount of current flows through the motor, as compared with a section in which a small amount of current flows through the motor, while the current flows from the battery to the motor. 15

2. The binding machine according to Claim 1, wherein the control unit is configured to limit the current flowing through the motor by a control of starting rotation of the motor.

3. The binding machine according to Claim 1 or 2, wherein the control unit 20 is configured to limit the current flowing through the motor by a control of stopping rotation of the motor.

4. The binding machine according to any one of Claims 1 to 3, wherein the control unit is configured to limit the current flowing through the motor, in response to an 25 environmental temperature of the motor.

5. The binding machine according to any one of claims 1 to 4, wherein the control unit is configured to limit the current flowing through the motor, based on a magnitude between a motor current value flowing through the motor and a threshold value.

6. The binding machine according to Claim 5, wherein the motor current value flowing through the motor and the threshold value are made relatively variable.

7. The binding machine according to any one of Claims 1 to 6, wherein the binding unit comprises a locking member configured to lock the wire, a sleeve configured to actuate the locking member, and a rotary shaft configured to actuate the sleeve, wherein the rotary shaft comprises a feeding screw configured to convert rotation of 5 the rotary shaft into movement of the sleeve along an axis direction of the rotary shaft, and wherein a lead angle of the feeding screw is 8° or more and 15° or less.
