Abstract
A strapping apparatus for strapping articles with a strapping band having a tensioning device for imparting a band tension to a loop of the strapping band, the tensioning device including a driveable tensioning element provided for engaging the strapping band to impart a band tension. The strapping apparatus including a connecting device for generating a permanent connection, in particular a welded connection, at two regions, situated one above the other, of the loop of the strapping band. The strapping apparatus is configured to achieve the release of the tensioning element from the strapping band reliably to avoid or reduce adverse characteristics attributed to the release of the tensioning device from the band.
Claims29
A strapping device comprising:
- a base plate;
- a tensioning plate on the base plate;
- a rocker pivotable about a rocker axis from a first rocker position to a second rocker position;
- a tensioning wheel pivotable with the rocker such that movement of the rocker from the first rocker position to the second rocker position moves the tensioning wheel away from the tensioning plate and movement of the rocker from the second rocker position to the first rocker position moves the tensioning wheel toward the tensioning plate, wherein the tensioning wheel is rotatable about a tensioning-wheel axis in a tensioning direction and in a reverse direction opposite the tensioning direction;
- a blocking element indirectly connected to the tensioning wheel and rotatable about a blocking-element axis in a first rotational direction;
- a shaft having a shaft axis;
- a lever movable between a first lever position and a second lever position, wherein when the lever is in the first lever position, the blocking element is prevented from rotating in the first rotational direction such that, after the tensioning wheel tensions strap around an object, the blocking element prevents the tensioning wheel from rotating in the reverse direction, wherein when the lever is in the second lever position, the blocking element is rotatable in the first rotational direction to enable the tensioning wheel to rotate in the reverse direction;
- and
- a rotatable element rotatable about the shaft axis and configured to force the lever to move from the first lever position to the second lever position as the rotatable element rotates about the shaft axis.
