Abstract
A device for the automatic cleaning, testing, and sorting of discoidal, flat substrates (9, 9', . . . ) for example magnetic memory plates, having three support mandrels (12, 13, 23) for the substrates (9, 9', . . . ) to be treated, three magazines (6, 7, 8) to deposit the treated and the untreated substrates (9, 9', . . . ), and having a transporting device fixed to a machine frame (2) or a machine support with several transferring arms (14, 15, 16) which can be moved on several levels and which are equipped with gripping devices (20, 21, 22) is provided with a motor-driven first support mandrel (23) rotating round its longitudinal axis (r) and with a nozzle (25, 26) disposed directly adjacent to said support mandrel in order to apply a cleaning liquid onto the substrate (9, 9', . . . ) which is firmly held by the first support mandrel. Moreover, each of the two further support mandrels (12, 13) disposed next to the first support mandrel (23) are provided with a scanning and testing device (27); the first transferring arm (14, 14', . . . ) serves to transport the substrate (9, 9', . . . ) from the first magazine (6) to the first support mandrel (23) and the second transferring arm (15, 15', . . . ) serves to transport the substrate (9, 9', . . . ) from the first to the second support mandrel (12) and the third transferring arm transports the substrate (9, 9', . . . ) from the second to the third support mandrel and from the latter to a second or third magazine (7 or 8). An electrical circuit which is disposed in the machine frame interacts with the testing device (27), thus actuating the motors of the transferring arms (14, 15, 16).
