Abstract

A strapping tool configured to tension metal strap around a load and, after tensioning, attach overlapping portions of the strap to one another by cutting notches into a seal element positioned around the overlapping portions of the strap and into the overlapping portions of the strap themselves.

Claims (16)

1. A strapping tool comprising:

a support;

a sealing assembly comprising opposing movable jaws for cutting notches into a seal element;

a tensioning assembly mounted to the support and pivotable relative to the support about a tensioning-assembly-pivot axis between a strap-tensioning position and a strap-insertion position, wherein the tensioning assembly comprises a tension wheel and tensioning-assembly gearing operably connected to the tension wheel to rotate the tension wheel about a tension-wheel rotational axis that is spaced-apart from the tensioning-assembly-pivot axis;

intermediary gearing comprising an intermediary gear rotatable about the tensioning-assembly-pivot axis and operably connected to the tensioning-assembly gearing to drive the tensioning-assembly gearing; and

a motor operably connected to the intermediary gearing to rotate the intermediary gearing about the tensioning-assembly pivot axis,

wherein the motor comprises a motor output shaft operably connected to the intermediate gearing by a belt, and wherein a rotational axis of the motor output shaft and the tensioning-assembly-pivot axis are parallel.

2. The strapping tool of claim 1 , wherein the tension-wheel rotational axis and the tensioning-assembly pivot axis are parallel.

3. The strapping tool of claim 2 , wherein a distance between the tension-wheel rotational axis and the tensioning-assembly pivot axis remains the same as the tensioning assembly pivots between the strap-tensioning position and the strap-insertion position.

4. The strapping tool of claim 2 , wherein the tensioning-assembly gearing comprises a driven gear and wherein the intermediary gear is drivingly engaged to the driven gear.

5. The strapping tool of claim 4 , wherein the tensioning assembly is mounted to the support via a tensioning-assembly pivot shaft, and wherein the intermediary gear is mounted to the tensioning-assembly pivot shaft and rotatable relative to the tensioning-assembly pivot shaft.

6. The strapping tool of claim 5 , wherein a distance between the tension-wheel rotational axis and the tensioning-assembly pivot axis remains the same as the tensioning assembly pivots between the strap-tensioning position and the strap-insertion position.

7. The strapping tool of claim 5 , wherein the intermediary gear is a second intermediary gear, wherein the intermediary gearing further comprises a first intermediary gear, wherein the first and second intermediary gears rotate together about the tensioning-assembly pivot axis, wherein the motor is operably connected to the first intermediary gear to rotate the first and second intermediary gears about the tensioning-assembly pivot axis.

8. The strapping tool of claim 7 , wherein the motor is operably connected to the first intermediary gear via the belt.

9. The strapping tool of claim 6 , further comprising a freewheel mounted to the motor output shaft, wherein the belt operably connects the freewheel to the first intermediary gear to operably connect the motor to the first intermediary gear, wherein the freewheel rotates with the motor output shaft in a first rotational direction and does not rotate with the motor output shaft in a second rotational direction opposite the first rotational direction.

10. The strapping tool of claim 9 , wherein a distance between the tension-wheel rotational axis and the tensioning-assembly pivot axis remains the same as the tensioning assembly pivots between the strap-tensioning and strap-insertion positions.
