Abstract
Various embodiments of the present disclosure provide a strapping tool including a tensioning assembly, a scaling assembly, a motor, and a transmission assembly. The transmission assembly operably connects the motor to the tensioning assembly and the sealing assembly. The motor can (via the transmission assembly) alternately drive the tensioning assembly to tension a loop of strap around a load and the sealing assembly to seal the strap to itself. The strapping tool also includes a locking assembly that prevents the motor from driving the sealing assembly via drag torque generated by the transmission assembly while the motor is driving the tensioning assembly.
Claims18
A strapping device comprising:
- a tensioning assembly comprising tensioning-assembly gearing operably connected to a tension wheel to rotate the tension wheel;
- a sealing assembly comprising sealing-assembly gearing;
- a motor operably connected to a drive gear to drive the drive gear in a first rotational direction and a second rotational direction opposite the first rotational direction;
- and
- a transmission assembly comprising:
- first gearing operably connecting the drive gear to the tensioning-assembly gearing such that rotation of the drive gear in the first rotational direction drives tensioning-assembly gearing to rotate the tension wheel in a tensioning rotational direction;
- and
- second gearing operably connecting the drive gear to the sealing-assembly gearing such that rotation of the drive gear in the second rotational direction drives the sealing-assembly gearing;
- and
- a locking assembly engaged to the second gearing to prevent the second gearing from driving the sealing-assembly gearing when the motor is driving the drive gear in the first rotational direction.
