As shown in detail in Fig. 5, the grippers 105 of the clamp 5 are rotated at the point 27 on these pairs of threaded sleeves 24 and their lower ends connected by links 28 with the working plate 29, which through its corresponding moving up and down creates a corresponding image of the desired self-centering movement of closing and opening the clamp jaw 5, as shown in solid lines and dotted lines, respectively in Fig. 5, this vertical movement plate 29 closed�captivity at the upper end of the rod 30, which passes with sufficient clearance and side closing element through the axial lumen of the shaft 126 and which, as shown in Fig. 3-6, emerges from the other end of the shaft for connection with the cylinder and piston element 31 located intermediate the overrunning clutch 32. The cylinders 9, 9' for raising and lowering the supporting structure 6 have the function of the introduction tank 1 in the phase of raising the sterilization chamber 10 and the connection of the movable flange 20 with the lower flange 310 of the camera, but they don't have the features of resistance to high pressures that develop in the chamber during the process of sterilization of the waste, since this function is performed by other means, which will now be disclosed with reference to Fig. 3, 4, 6 and 7. A pair of supports 17, 17' (Fig. 3-6 and 8) attached to the racks 142 of the frame 42 of the machine, is provided at two diametrically opposite regions of the flange 310 and at a short distance from the flange. On supports 17' at the points 33, 33' are slightly curved outward ends 134, 134' of seizures made by pairs of plates 34, 34', which in plan view have the shape of a sector of a circle a little less than 180 degrees, the opposite ends 234, 234' capture point outward and pressed to each other by at least one elastic means 35 attached to these seizures, while the housing of the hydraulic cylinder of the node 36 is installed on the rotary axis 136 OnEnd 234 capture 34, stock of this item installed on the rotary axis 236 at the opposite end 234 of the grip 34'. These pairs of plates forming the curved grippers 34, 34', are interconnected by crosspieces 334, 334', arranged at an angular interval of 90 degrees, the intermediate yoke deploy to the middle of the corresponding swinging arm 38, 38', which is also performed by a pair of parallel plates (Fig. 6 and 7) and that seems like a sector of a circle when viewed from above and has a ring amplitude of about ninety degrees. At the ends of these swinging of the lever by means of pins 39, 39' are rotated blocks 40, 40', resembling sectors of circles when viewed from above and having an essentially Y-shaped cross-section, each block has a groove with a profile of an isosceles trapezoid facing the sterilization chamber 10, the outer long, the base and inner shorter base of the trapezoid, having a size in the elevation, which, respectively, more and less than the sum of the thickness of the flange 310 and part 120 based together with this flange to flange 20. As shown in detail in Fig. 6 and 7, the blocks 40, 40' have sufficient degrees of freedom to oscillate at the corresponding pins 39, 39' to the entrance into contact with the respective plates of the supporting rocker arms 38, 38', and the ends of the pins 39, 39' are passed through the slits 37, 37' arranged in pairs of plates forming the grippers 34, 34', thus, Starachowice levers have ample oscillations around their middle nucleus 334, 334'. Curved grippers 34, 34' together with the corresponding pairs of blocks 40, 40' form a releasable clamp which encloses the node formed by the lower flange 310 of the sterilization chamber and the underlying flange 20 which rests upon him, and releasable clamp is a function of the interaction of floating centripetal manner with the stack formed by these flanges 310, 20, so exactly adapted to their round shape and provides the necessary axial support for keeping them closed against high pressure, which develops in the chamber 10 during the process of sterilization of the waste. Before tank 1 is inserted into the chamber 10, while the carriage 6 is still in the lower position, shown in Fig. 4, the piston rod of the cylinder node 36 continues to move the grippers 34, 34' from each other, resisting the action of the spring 35 until the ends 234, 234' is not summed for supporting the protruding lugs on the stops 41, 41' attached to the supports 17 (Fig. 3 and 6). In this state both of the gripper 34, 34' and the blocks 40, 40' are involved and suitably removed from the lower flange 310 of the sterilization chamber 10 for the purpose of no intersections with the flange 20 integral with the carriage 6 when the latter is raised for the introduction of the tank 1 into the chamber 10. Upon completion of injection, the piston-cylinder node 36 is provided � action to retract its piston rod and closing of the grippers 34, 34', by means of a spring 35, the respective blocks 40, 40', placed floating centripetal manner on the perimeter of the site of the flanges 310 and 20, as shown in Fig. 6 and 7, so that the interaction of the inclined planes of the grooves of the blocks on the upper and lower edges of these flanges node 310 and 20 causes the closing of a site and maintain it in the closed position with minimal force applied to the piston-cylinder node 36. The inclined surfaces of the chutes blocks 40, 40' have the function essentially reduce the effort of the cylinder node 36, as this force is proportional to the sine of the angle of the inclined planes of the mentioned trapezoidal troughs blocks.

Because the duty cycle of the sterilization chamber 10 is the longest of all cycles of the various components of the machine, provided with a sterilization stations of the type described, the invention provides a machine with the scheme shown in Fig. 8, with the provision of two or more sterilization stations SS1, SS2, adjacent to each other on one side of the linear frame 42, and with the provision on the same side, at increasing distance from the first specified station SS1, station SC for filling tanks, 1 waste station and SSC for discharging the sterilized waste from the tanks coming from these stations SS1, SS2. On the same side of the frame 42, carrying the work�their station, provided with suitable automatic means of manipulation of tanks to move tanks in a closed cycle between the various above-mentioned stations. Satisfactory results in terms of reliability and reduced overall dimensions were achieved by using manipulative means SM running on at least two orthogonal axes, namely a longitudinal axis, indicated by the double arrow X to move from one station to another, and the transverse axis, indicated by the double arrow Y to move to and from the stations. As shown in Fig. 8 and 9, these funds include SM horizontal guide piece 43, parallel to the axis X and having a suitable length, which moves the slider (not shown) carrying orthogonal to the guide element, which moves the slider 44 that is parallel to the Y-axis, which supports the head portion 45 in the form of a box-shaped parallelepiped, with its greatest dimension, parallel to the guide element 43, the wall of the head portion facing the stations carrying two speakers adjacent self-centering clamping P1 and P2, each of which has a pair of flat grips in the shape of a sector of a circle to capture these base plates 2 tank top 1 trough 4, these grippers are attached to a movable drive elements 46 commercially available type, such as pneuma�quarter drives with electric sensors, which recognise open and closed state of the gripper, which is pushed into the closed position the respective springs 47. Clamp P2 is adapted to perform the opening and closing movement of only the corresponding capture and used to lift a full tank with filling station SC on sterilization stations SS1, SS2, while the clamp P1 also is adapted for opening and closing, as well as to rotate around an axis parallel to the axis Y, for example, by rotating ninety degrees, and is used for extraction tank 1 with sterilization stations SS1, SS2 and placing them at the discharge station SSC. This goal is achieved by raising the pneumatic actuator, which actuates the capture clip R1 on the shaft 48 (Fig. 9) rotatable support means integral with the head part 45, this shaft is provided with a knee 49, connected with the rod of the cylinder and piston node 50, the body of which rotate at the point 51 on the support in the head part 45. Rotating collectors, easily performed by specialists in this field and for this reason not shown, may be provided to allow opening and closing of the clamp P1 line delivery and unloading of the drive elements 46 and electrical circuits of the sensors to pass through the shaft 48. In a simpler alternative solution kasansaiskii and pneumatic circuits of the clamp P1 can be flexible can be directly connected with the driving elements 46 of the clamp and can climb in the flexible pipe, which passes through a hole in the head portion 45 for the connection of components located in the head part. All the contours and lines required for the operation of the moving parts of the station CM, can be connected to a fixed panel delivery and unloading through the contours and lines that are spaced crawler transmission medium 71, shown in Fig. 8. Grippers clip P1 are horizontal when he lifts tank from a self-centering clamp 5 rotatable plate 23 sterilization station and remains in this position until it reaches the unloading station SSC, where the clamp is rotated at 90 degrees to the horizontal location of the tank, as shown in Fig. 9, so that the clamp rests on the support arm affixed to and projecting from the head portion 45. In this state, the head portion 45 is moved horizontally along the X-axis to be placed in the tank 1 with the sterilized waste at the station SSC, which essentially consists of a horizontal screw having such a diameter that it can enter the tank 1 to empty, and the guide element 54 in the form of a spear, which prevents the rotation of the waste and ensures their transfer and discharge screw. The screw 53 has a length that is suitably larger than the height of the tank 1, and he raised�recover it on the outlet shaft of the motor 55 with gear, fixed to the arm 242 of the frame 42 of the machine (Fig. 8). Screw the node 53, 54 protected with sufficient clearance casing 56, open downward, and the lower part of which is connected by suitable means 57 for the Assembly discharged the waste or transfer to a distant position (Fig. 8). Fig. 10 shows that the screw shaft 53 is hollow along its axis and provided with a nozzle with a nozzle 58 for releasing the at least one fluid under pressure, such as air and/or water which is supplied to the rotating shaft through the connection 59 to ensure that the tank 1 is suitably cleaned inside to remove from the station SSC and the re-introduction of a new working cycle. After unloading and cleaning head portion 45 is pulled horizontally to remove the tank from the screw 53, and at the end of the retracting clamp P1 is rotated ninety degrees to return the tank to a vertical position, with the hole facing up, and in this position the tank is aligned and inserted manipulator in SM unloading station SC, having means to support the tank, which will be described later with reference to Fig. 11-13. Fig. 8 and 11 shows in greater detail how the tank 1, the emptied at an unloading station SSC, holding the bottom of the groove 4 by means of clamp P1 and is positioned vertically and follow the translational motion of the head portion 45 along the Y axis, this is the head part over open Sahu�Tami 105 self-centering clamp 5', similar to the clamp 5, which is a sterilization stations SS1, SS2, but which, unlike the last clip, is provided for the sole purpose of rotation, and not with the purpose of providing lifting and lowering movements, and is located in the lower part of the filling station SC. The bottom plate 25' is attached to the issuing of the motor shaft 26 with a gear casing attached to the frame 42 of the machine and is provided with, as shown in the arrangement of Fig. 4, in the lower part of the cylinder and piston hub 31' and an overrunning clutch 32' for actuating the working plate 29' which by means of links 28' takes the required swing of the grippers 105' for their opening and closing movements.
