Abstract
To improve welds implemented by a friction welding tool for a strapping apparatus, where said tool comprises a drive of which the output is convertible by means of a compliant mechanism into an oscillating motion of a welding shoe, the present invention proposes an approximately polygonal drive element (20) configured as seen in the direction of transmission of the drive motion, between the drive and the welding shoe (9), said element being fitted with a peripheral surface (24) that, in relation to an axis of rotation (18a) comprises at least three zones (30a, 30b, 30c) which from their periphery are more distant from the axis of rotation (18 than are other zones (31a, 31b, 31c) of said peripheral surface (24).
Claims (15)
1. A friction welding tool for a strapping apparatus, said tool being fitted with a drive of which the output motion is convertible by a gear unit into an oscillatory motion of a welding shoe, characterized by an approximately polygonal drive element (20) which is configured, as seen in the direction of transmission of the drive motion, between the drive and the welding shoe (9) and which is fitted with a peripheral surface (24) that comprises at least three zones (30a, 30b, 30c) which are configured about an axis of rotation (18a) and which are a greater distance to the axis of rotation (18a) from their periphery than other zones (31a, 31b, 31c) of said peripheral surface (24).
2. Friction welding tool as claimed in claim 1, characterized in that the drive element (2) comprises an odd number of zones (30a, 30b, 30c) being at a greater distance from the axis of rotation (18a).
3. Friction welding tool as claimed in one or both of the above claims, characterized in that at least one contacting element rests against the drive element (20), said contacting element itself carrying out a motion caused by the rotary motion of the drive element (20).
4. Friction welding element as claimed in claim 3, characterized in that the contacting element is operationally connected to a mechanism driven by the contacting elements, a translating reciprocating motion thereby being transmissible from the mechanism to the welding shoe (9).
5. Friction welding tool as claimed in claim 4, characterized in that the mechanism is a lever mechanism.
6. Friction welding tool as claimed in claim 5, characterized in that the compliant lever mechanism comprises parallelogrammatic lever linkages.
7. Friction welding tool as claimed in claim 6, characterized in that the minimum of one contacting element is mounted to a guide bracket (29) that is part of the parallelogrammatic linkage system.
8. Friction welding tool as claimed in at least one of the above claims, characterized in that the drive element (20) is configured between two contacting elements each of which is in contact with the peripheral surface (24) of the drive element (20).
9. Friction welding tool as claimed in claim 8, characterized in that the two contacting elements preferably are always moved synchronously by the drive element (20).
10. Friction welding tool as claimed in at least one of the above claims 8 and 9, characterized in that the distance between the two contacting elements is substantially constant during a rotation of the drive element (20).
11. Friction welding tool as claimed in at least one of claims 2 through 10, characterized in that at least one contacting element is displaceable along a straight path of displacement (25).
12. Friction welding tool as claimed in claim 11, characterized in that the minimum of one contacting element is displaceable along a path of translation,
13. Friction welding tool as claimed in at least one of the above claims, characterized in that a zone of larger distance from the axis of rotation always is diametrically opposite a zone of lesser distance from said axis of rotation.
14. Friction welding tool as claimed in at least one of the above claims, characterized in that a drive motion for the welding shoe may be generated manually.
15. Strapping apparatus, in particular a portable strapping apparatus, to strap an item to be packed with a plastic strap, comprising -- a tensioner to apply sufficient tension to a strap loop, -- a clamp allowing clamping the tensioned strap, and -- a friction welding tool to generate a weld connection at two mutually overlapping strap plies, characterized by a friction welding tool as claimed in at least one of the above claims 1 through 14.
