Working of the automatic labelling system
The tubes are loaded manually in the rack in reference to Figure 1 depicting the 6 rows (1a-1f) designed as per the preferred embodiment of the present invention. The rows are configured to secure or load two types of tubes viz. Ø 13 X 75 mm and Ø13 X 100 mm long tubes for specific tests. Depending on the hospitals, the types of tubes used for specific test varies. In general, within these sizes there 10 different tubes. So a preferred embodiment of the present invention the automated labelling machine, termed herein as Mispa label, is constructed to assign a maximum of 6 specific tubes in 6 rows. Multiple rows for a specific tube can also be assigned as per the need. The rows 3 & 4 can be preloaded with tubes of length 75 mm and 100 mm whereas the rows 1, 2, 5, 6 can only be preloaded with 75 mm tube. An actuator for dropping the specific tubes from each row as required is mounted on each plate. The 75 mm long tubes can be loaded in all the 6 rows whereas the 100 mm long tubes can only be loaded in the topmost 4 rows. The rows 3 & 4 can be preloaded with tubes of length 75 mm and 100 mm whereas the rows 1, 2, 5, 6 can only be preloaded with 75 mm tube. An actuator for dropping the specific tubes from each row as required is mounted on each plate. Each row in the rack is assigned a specific tube depending on the colour of the cap and the tube used for specific tests as needed in the setting menu by means of a display. The equipment comprises of a storage apparatus for storing a correspondence relation between the type of the test tube and the color of the cover of the test tube. The equipment also comprises of a voice prompting apparatus for any error/warning/status of the labelling and printing etc is available.

The tubes are held in the rows by solenoids (2a, 2b, 2c, 2d, 2e, 2f, 9, 10). The equipment uses TCP/IP Protocol to read the data and Tube category to print from LIS in connection with network enabled device where the input data of the patient is entered. With respect to the category read, it decides the row (1) in which the corresponding tubes is filled and activates the solenoid (figure 2) to drop one tube at a time. The tube drops in to the tube vent (3), through the tube guide (4) and further to Labelling chamber (5). The falling is achieved by gravity because of the 22° angle on the rack. In the labelling chamber (5), the tube is held by an L angle (8) which is in turn mounted to a solenoid called as tube solenoid (9). A tube sensor (6) detects whether the tube is present in the labelling chamber (5). If the sensor detects the tube, label solenoid (10) is actuated and the idler assembly (11) which is connected to the label solenoid will press on the tube to hold it firmly while the tube is rotated to paste the label using the primary printer (12). A sensor named label sensor (7) is strategically placed to detect the edge of the existing label on the tubes. The tube is rotated for three complete rotations to identify the left edge of the tube. On the fourth rotation, the angle made by the circumference of the existing label is identified. Since different tubes have different label of circumference, a percentage of the angle is put as an offset to make sure that the label is pasted in such a way that there is always a visible area and the marking on the label is visible to identify the volume of blood to be drawn in the tube. Once the labelling is complete both the solenoids (9, 10) retracts to eject the tube from the labelling chamber and to the collection tray (13), when the sample is blood. Body samples like urine, sputum etc are collected in different tubes which cannot be printed using primary printer (12). There is an auxiliary printer (14) which can cut the labels into tickets by the inbuilt cutter and ejected to the collection tray (15) for auxiliary printer. These tickets can be manually pasted on the containers by the user. Both the primary printer (12) and the auxiliary printer (14) along with other parts are mounted on to a drawer assembly (16) and are mounted on the telescopic rail (17). The drawer assembly is then mounted on to the enclosure assembly (18). For non-blood samples the auxiliary printer [14] is actuated to print the label in the labelling apparatus and the inbuilt cutter of the printer cuts the labels, eject it via the ejection port [21] to the collection tray [15] for manual adhering to the respective tubes.

Another preferred embodiment of the present invention discloses a method of labelling of tubes by an automated labelling system, comprising of steps:
Determination of print label data based on test category provided as input in a network enabled device; Manual loading of the tubes in the rack (1);
selection of the tube from a respective row of rack (1) by actuation of the solenoid (2) on rack (1) to drop the tube to the labelling chamber (5) via the tube vent (3) through the tube guide (4);
