Title:
BINDING MACHINE
Document Type and Number:
Japanese Patent JP2023064353
Kind Code:
A
Abstract:
To provide a binding machine capable of smoothing a time required for a binding operation while suppressing a load applied to a motor and heat generation of the motor.SOLUTION: A reinforcing bar binding machine includes a limiting circuit 100 that cuts off and restores energization to a motor 80 and a feed motor 31 in accordance with a battery voltage. The limiting circuit 100 includes: a current detection circuit 103 for detecting a current flowing through the motor 80 and the feed motor 31; a comparator unit 104 for outputting a cutoff signal Sg2 when a motor current value Va flowing through the motor 80 detected by the current detection circuit 103 or the motor current value Va flowing through the feed motor 31 becomes equal to or greater than a current limit threshold value Vr; and a gate driver 105 for cutting off a gate signal Sg1 output from a microcomputer 101 when a cutoff signal Sg2 is input from the comparator unit 104, wherein a current flowing from a battery 15 to the motor 80 and the feed motor 31 is cut off.SELECTED DRAWING: Figure 8B
