摘要:
Device and method for operating a device, having a storage device, an evaluation device and a weighing unit. The weighing unit has a unique identification key. A corresponding characteristic pass code is stored in the storage device for the identification key of the weighing unit. The evaluation device derives a data record containing weighing data from the measured data determined with the weighing unit. The evaluation device checks the congruity between the pass code stored in the storage device and the identification key of the current weighing unit. The evaluation device determines a positive test status if the pass code stored in the storage device is found to be congruous with the identification key of the current weighing unit. The evaluation device determines a negative test status if no matching pass code is found in the storage device for the identification key of the current weighing unit. The data record is output as a calibrated data record if the test status is positive and a non-calibrated data record if the test status is negative.
摘要:
The invention relates to a device and to a method for fitting and filling valve bags (2), comprising a bag fitting device (10) for fitting the valve bags, a gripper device (4) and a fitting device (5), wherein the gripper device is provided for gripping an empty valve bag, and wherein the fitting device is suited for fitting a valve bag on a filling nozzle (27) of a rotating packing machine (1) equipped with a plurality of filling nozzles. A movement of the gripper device can be controlled by a rotatable eccentric device, and the eccentric device can be rotated using a motor in order to periodically receive valve bags and fit them by means of the fitting device.
