The patented bag closing system “Over Tape Bag Sealer” from STATEC BINDER seals woven polypropylene (PP) bags airtight. A woven PP tape is used for a reliable and secure closure. If necessary, the bags can also be sewn. Both pillow bags and gusset bags can be securely closed. This sealing technology facilitates the handling of dusty and odour-intensive products of the food and feed industry. During operation, the filled bags are transported to and from the bag closing system via a conveyor belt. A sensor detects the position of the bag and automatically puts it into the trimming area. After cutting the top edge of the bag a woven PP tape is applied over the open edge of the bag to seal it with hot air. The hot air to seal the bag airtight and odourless is produced by a heating unit in the machine.

igm gas nozzle searching - Tactile sensor for position detection This tactile sensor is used to determine the workpiece position or its components and individual parts by gauging the surface of the workpiece. In each case, the successional part of the program is shifted according to determined deviations. Sensor shifting may be applied for correction of an arbitrary amount of individual points, entire sections of a welding program or entire programs. Combination with arc seam sensing is feasible. The control system supports shifting, rotating, and tilting of a program, depending on position change. The gas nozzle itself is used as a sensor. This makes it possible - even on complicated workpieces and in confined spaces - to perform the required search steps on the reference surfaces of the workpiece, by which the position of the weld seams is determined. As soon as the gas nozzle gets into contact with the work piece, it is discharged and the robot stops immediately. This...
