Mobile strappiing device

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 transitioning device operatively connected to the friction welder and configured to move the friction welder from a rest position into a welding position, the transitioning device including a toggle lever device having a first arm and a second arm connected to the first arm;
• and
• a chargeable energy storage device configured to store energy, which can be released as drive energy for motorized drive motions at least for the friction welder for producing a friction weld connection, characterized by a common drive for the tensioner for producing a tensioning movement, for the friction welder for producing an oscillating friction welding movement, and for the transitioning device for producing a transfer movement of the friction welder from the rest position into the welding position, wherein the common drive drives the tensioner when the common drive is rotated in a first direction and the common drive drives the friction welder and the transitioning device when the common drive is rotated in a second different direction,
• wherein the mobile strapping device is configured such that:
• (i) force from the common drive is transferred to the first arm of the toggle lever device, thereby imparting movement in one of a clockwise direction and a counterclockwise direction;
• and (ii) the movement of the first arm causes the second arm of the toggle lever device to move in the other of the clockwise direction and the counterclockwise direction, which movement of the second arm produces the transfer movement of the friction welder.

• a transitioning device operatively connected to the friction welder;
• a common drive for the friction welder for producing an oscillating friction welding movement, for the tensioner for producing a tensioning movement without producing the oscillating friction welding movement, and for the transitioning device for producing a transfer movement of the friction welder from a rest position into a welding position;
• and
• a planetary gear system operatively coupled to the common drive and the friction welder such that the planetary gear system can change and transfer a rotational speed of the common drive to the friction welder for producing the oscillating friction welding movement.
