  • Patent number: 11331746
    Abstract: The invention relates to a device and a method for changing the welding direction of the welding shoulder of a system for a friction stir welding process virtually without delay when required by the geometric arrangement of the joint partners to be welded or by a material unevenness, having the following method features: a) a main part (1) with a horizontally movable bridge support (5) has a friction welding head (12) which can be vertically adjusted together therewith and which has a pin receiving area (13) for mounting and driving a welding pin tip (14), wherein the welding shoulder (18) has a welding shoulder receiving area (17) which is supported at multiple points, and b) the welding shoulder receiving area (17) can be adjusted to any angle of attack relative to the joint partners by means of different push-pull rods (16) during the welding process.

  • Patent number: 8870515
    Abstract: Disclosed are a device and a method for picking up glass plates from at least one production line in order to convey said glass plates on to a storage housing or a coating plant. An embodiment of the device includes: a) a linearly movable, vertically installed main lifting column with a lifting rake that can be vertically moved therealong; b) a horizontal drive unit for the lifting rake; c) at least one sensor which is mounted on a fork of the lifting rake and is used for detecting the availability of the targeted storage place of a glass plate; d) at least one sensor which is mounted on a fork of the lifting rake and is used for detecting if a glass plate is located on the lifting rake; e) at least one sensor that is mounted on a fork of the lifting rake and is used for detecting cracks in a glass plate.
