Abstract
A tying machine may include a twisting mechanism configured to twist a tying string. The twisting mechanism may include a twisting motor. The tying machine may be configured to obtain torque acting on the twisting motor as a twisting torque value, and stop the twisting motor when a predetermined tying completion condition is satisfied. The tying completion condition may include that an elapsed time since a rise in the twisting torque value was detected reaches a first predetermined time.
Claims18
A tying machine comprising:
- a twisting mechanism configured to twist a tying string, wherein the twisting mechanism includes a twisting motor;
- and
- a processor that is configured to:
- obtain torque acting on the twisting motor as a twisting torque value;
- detect a rise of the twisting torque value;
- and
- stop the twisting motor when a predetermined tying completion condition is satisfied,
- wherein the tying completion condition includes when an elapsed time reaches a first predetermined time after the rise in the twisting torque value was detected, and
- when a predetermined cancellation condition is satisfied after the rise in the twisting torque value has been detected, the processor is configured to cancel detection of the rise in the twisting torque value and continue twisting of the tying string without stopping the twisting motor.
