Strapping device with an energy storage means

A mobile strapping device for strapping packaged goods with a loop of wrapping strap, comprising:

• a tensioner configured to apply a strap tension to the loop of wrapping strap;
• a connector configured to produce a friction weld connection at two areas of the loop of wrapping strap disposed one on top of the other by way of reciprocating movement of a friction welding element;
• a motor operatively coupled to the tensioner to drive the tensioner;
• a planetary gear system operatively coupled to the motor and the connector to transfer drive movements of the motor to the connector to cause the reciprocating movement of the friction welding element;
• a chargeable energy storage device configured to store energy that can power the motor;
• and
• an output device configured to output an indication when the energy stored by the energy storage device is no longer suitable to enable the connector to produce a friction weld of a designated quality.

A method, comprising:

• strapping a packaged good with a loop of wrapping strap utilizing a mobile storage battery-driven strapping device, including:
• placing the loop of wrapping strap around the packaged good;
• driving a motor, which is operatively connected to a tensioner of the strapping device, to cause the tensioner to apply a strap tension to the loop;
• and
• driving the motor, which is operatively connected to a connector of the strapping device via a planetary gear system, to cause the connector to form a connection at two areas of the loop of the wrapping strap disposed one on top of the other by way of reciprocating movement of a friction welding element, wherein the planetary gear system transfers drive movements of the motor to the connector to cause the reciprocating movement,
• wherein the strap tension is applied by the strapping device and the connection is established by the strapping device utilizing energy from a chargeable energy storage device;
• and
• when the energy stored by the energy storage device is no longer suitable to enable the connector to form a connection of a designated quality, outputting an indication.
