Mobile strappiing device

摘要

Disclosed is a mobile strapping device for strapping packaged goods with wrap-around strap, including a tensioner for applying a strap tension to a loop of a wrapping strap, and a friction welder for producing a friction weld connection in two areas of the loop of the wrapping strap disposed one on top of the other, and a chargeable energy storage means for storing energy, in particular electrical, mechanical, elastic or potential energy, that can be released as drive energy at least for the friction welder for producing a friction weld connection. The strapping device is provided with a common drive for the tensioner for producing a tensioning motion, and for the friction welder for producing an oscillating friction welding motion and for a transitioning device for producing a transitioning motion of the friction welder from a rest position to a welding position.

主权项

1. A mobile strapping device for strapping packaged goods with a loop of wrapping strap, the mobile strapping device comprising:
a tensioner configured to apply a strap tension to the loop of wrapping strap; a friction welder configured to produce a friction weld connection by way of a friction welding element at two areas of the loop of wrapping strap disposed one on top of the other; a common drive for the tensioner for producing a tensioning movement, for the friction welder for producing an oscillating friction welding movement, and for a transitioning device for producing a transfer movement of the friction welder from a rest position into a welding position, wherein the common drive drives the tensioner when the common drive is rotated in a first direction and drives the friction welder and the transitioning device when the common drive is rotated in a second different direction; a chargeable energy storage device configured to store energy that can be released as drive energy for motorized drive motions of the common drive; and a planetary gear system configured to change and transfer a drive movement of the common drive to the transitioning device to produce the transfer movement.
