Abstract: A method and system for auto safety verification of automatic guided vehicle (AGV) sensors is presented. An auto safety verification test can be performed autonomously by the AGV to ensure that sensors on the AGV are configured correctly and working properly. The auto safety verification test avoids human errors that exist in manual verification tests and significantly reduces the amount of time required to verify sensors on the AGV.

Abstract: This relates to an inexpensive blast wheel for applying abrasive particles to work pieces to be cleaned. The blast wheel provides a simple arrangement for supporting vanes in the form of a hub having a bowl shaped portion in which bases of vanes are seated with the bases being clamped in place by a plate portion of an impeller. Each vane includes a wide base connected to the vane by way of a spacer. The impeller plate has a notch for each vane with the notch receiving the spacer and overlying the base. The bowl portion of the hub includes a peripheral flange which engages an outer end of the vane base to restrain it against radial outwardly directed movement. The vanes may be changed by providing the hub flange with a notch through which a vane base may pass. By loosening the impeller plate relative to the hub, and aligning each vane in sequence with respect to the notch, the vane may be slid through the notch and removed from the hub.

Abstract: A method and apparatus for cleaning a succession of workpieces such as automobile engine blocks includes a first cleaning mechanism wherein cleaning media such as steel shot is directed against the workpieces. After being discharged from the first cleaning mechanism, the workpieces are inverted and passed through a second cleaning mechanism where cleaning media again is directed against the workpieces. In the second cleaning mechanism, the workpieces are separated so that the ends of the workpieces can be cleaned. The invention includes turning mechanisms for inverting the workpieces one-by-one, as well as devices for controlling the movement of the workpieces through the different cleaning and turning mechanisms.
