    The invention relates to the field of packaging equipment.
    The purpose of the invention is to increase the operational reliability of the nozzle.
    Figure 1 shows the connection of the nozzle before engagement with the shutter of the container; Fig. 2 shows the connection during sterilization or cleaning, the closure being partially engaged with the packing by the filling head; in FIG. 3, the same, during the supply of the product, the closure being fully engaged with the filling head; figure 4 - clamping device, a detailed view in section.
    The plug connection, through which the container-container 1 can be filled with the product, has a bolt 2 for the container and nozzles (filling head) .3 with which the bolt engages.
    A shutter 2 is installed in the opening 4 in the wall 5 of the container in order to close the opening during transmission and the like. The container may be a container for liquid or semi-liquid food products (for example, peaches in a syrup) and be formed from an internal containing bag made of a flexible plastic sheet, the wall 5 and the outer coating (not shown) made of triple corrugated cardboard which provides support and protection to the bag.
    Upon closer examination, the shutter 2 comprises a housing 6 having a rod 7 protruding outward through the container wall and an installation flange 8 inside the container, a fastening ring 9 screwed onto the screw thread 10 of the rod 7, to secure the shutter on the container by tightly clamping the container wall 5 around the hole 4 at the flange 8, and the valve 11, which engages with a through bore hole in the housing 6 with an interacting screw. 12,
    The valve 13 is shown in FIG., In the position when it is completely screwed into the housing 6. In this position, it closes the bore hole in the housing from access of the product flow by engaging the sealing edge on the valve 13 with a smooth shchirshdrichesky surface 14, forming

    part of the bore hole of the housing.
    A sealing lip is formed on the mushroom head 15 of the valve. The valve is made of an elastic plastic material, for example nylon. on, and the ring 16 is installed in a groove in the mushroom head 15 to ensure hermetic engagement of the sealing edge with the surface 14, exerting a directed compressive force radially outward on the peripheral edge of the head where the sealing edge is located.
    The valve has a blind hole 17 that opens into the inside of the container, the outer end of which is closed by the mushroom head 15, and a through hole 18 passing transversely through the valve to allow the blind hole to communicate with the outer part of the valve behind the mushroom head.
    The outer surface 19 of the mushroom head 15 has a diagonal groove 20, which may include an additional chamfer 21 on the valve 22 of the filling head 3, in order to connect the mushroom head 15 and the valve 22 for joint rotation. By rotating in the appropriate direction of the valve 22 of the filling head, the valve of the valve 11 can be unscrewed from the closed position to the open position, in which the through hole 18 is released from the free end of the valve body 6 in order to pass the product into the container.
    The valve 22 of the filling head has a mushroom-shaped head 23, made with a chamfer 21, and a shaft 24, which is mounted to perform rotational and axial movement relative to the body 25. The head 23 is shown in FIG. 1 in the closed position, in which the sealing edge 26 of the head creates a sealed the engagement with the cylindrical surface 27 provided on the housing 25. The engagement of the edge 26 and the surface 27 is similar to the engagement of the edge 13 and the surface 14 of the bolt 2, and a ring is also provided to ensure tightness.
    The chamber 29 is formed in the housing 25 behind the mushroom-shaped head 23 and is closed by the head in the shown 3
    lying. Pipeline 30 connects the chamber to the food storage tank (not shown). In the open position of the valve 22, the head is retracted into the chamber 29 so that the product can flow out of the chamber and past the head 23 and exit the filling head in the nozzle 31 formed in the housing 25 .
    The dimensions of the nozzle 31 allow the protruding free end of the stem 7 of the bolt 2 to be received. It has a pair of axially spaced sealing rings 32 and 33 mounted in its wall and placed separately to provide a hermetic engagement with the cylindrical outer surface 34 represented by the stem 7 behind the 9 fastening ring,
    The inlet channel 35 for superheated steam passes through the housing to enter the nozzle 31 between the rings 32 and 33. The steam leaves the filling head through the outlet 36 of the nozzle 31 and the screw device 37 (FIG. 3) providing a tapered opening 38, whereby the vapor pressure is maintained above atmospheric. A temperature sensor 39 coupled to the fixture 37 provides an electrical output dependent on the temperature along lines 40 and / or to a visual display.
    The respective inlet and outlet connections for steam are attached to the housing, respectively, at the inlet port 35 and the tool 37. These connections may have a control valve.
    The shaft 24, sealed by rings 41, protrudes from the head 23 and through the housing 25 to the drive mechanism 42 The actuator has a cylindrical housing 43 mounted on the housing and with a water cap 44 which is located above the free end of the cylindrical housing. The free end of the shaft 24 protrudes through the base of the drive hood and is connected to the bell for rotation with the help of a pin 45, which passes transversely through the shaft, and its ends are placed in opposite grooves 46, which are reinforced. at the base of the cap.
    In order to eliminate the possibility of penetration of microorganisms or
    17
    other soils in chamber 29 along shaft 24, drive housing 43 is arranged so that it restricts cylindrical chamber 47 around shaft and inlet and outlet openings 48 and 49 are provided, thanks to which the chamber has the ability to be continuously cleaned with steam under pressure that is supplied by atmospheric, supplied and discharged through appropriate compounds. The pressure spring 50, located in the chamber 47, moves the filling head valve 22 down to the closed position.
    The plug connection and its components, 3 particularly the closure of the container 2 and the filling head 3, operate and are used as follows.
    Containers 1, intended for filling with products, arrive at the plant from gate 2, with closed valves 11. To avoid large contaminants during transportation, protruding free ends of gate rods 7 are protected with plastic caps (not shown). The caps are removed, after which the containers in turn are attached to the filling head 3 so that, as shown in Fig. 1, the nozzle 31 and the stem of the container 7 are aligned coaxially. At this time, the valve 22 of the filling head remains closed, and the product is therefore in the chamber 29 communicating with the storage tank through line 30. It is clear that the hydrostatic pressure of the product on the valve 22 keeps it in the closed position.
    Since the container must be aseptically filled with the product, the outer surfaces of the closure and filling head that may come in contact with the product are sterilized.
    For this purpose, the shutter 2 and the filling head 3 are compressed together until, as shown in Fig. 2, the rod partially enters the nozzle 31 to engage with the outer sealing ring 32, which accordingly forms a seal. Steam under pressure and at sterilization temperature is fed through channel 35 into the empty space.
    five
    51 (Fig. 2), which remains in the nozzle, between closed valve heads 15 and 23, whereby the open surfaces of the gate and the heads lying between the sealing edges 15 are sterilized.
    After the period required for complete sterilization, the container and filling head are again brought together in order to fully insert the stem of the valve into the nozzle, for example using the clamping device 52 shown in FIG. 4. Thereafter, the drive cover 44 can be rotated manually to turn the shaft 24, and thus, when the chamfer 21 enters the groove 20, as shown in FIG. 3, open both valves by screwing the valve 11 along the valve body 6. Fig. 3 shows the complex when the valves are completely open: the product can thus flow into the container from the storage tank.
    It is especially emphasized that the valve of the filling head 22 is operated under the influence of the valve 1I and can be opened only when the filling head is engaged with the gate 2, whereby its outlet opening is hermetically sealed. Because of this, there is very little risk of product loss from the filling head valve in case of operator error. Moreover, for the valve itself to operate, the valve of the filling head is required, therefore the possibility of operator error is reduced.
    After a certain amount of product has passed into the container, the drive cap 44 rotates in the direction opposite to the direction in which the opening takes place, thereby moving the valve 11 to its closed position and allowing the spring 50 and g to the prostatic pressure of the product At the same time, valve 2 is closed in the chamber 29. After that, the container towards the filling head is separated to partially the entangled position shown in Fig. 2, for example, by releasing the clamping device 52, which provides access to the newly formed vapor space 51 for cleaning the exposed surfaces of the shutter 2 and filling the go17S
    Dexterity 3 from product residue. Preferably, the vapor pressure in the channel 35 is maintained mainly during the entire filling operation, i.e. during the time when the stem rod 7 partially or completely enters the nipple 31, which allows the sterile barrier to be maintained. Although the indicated operation of sterilizing the surfaces of chamber 51 before filling may require several minutes, the cleaning operation can be performed more quickly, and the corresponding partially engaged position (Fig. 2) is instantaneous.
    After cleaning, the container and filling head are completely uncoupled from and the container is replaced with an empty container 2 for the subsequent filling operation. Next comes the sequence of operations.
    In order to reduce the force required to engage the screw thread. 12 when opening and closing valves 11 and 22, and helping valve 22 of the filling head to follow valve 11 when closing, the inner opening of the drive assembly can, as shown in FIG. 3, have a screw thread along its length 53. Engagement with an additional screw thread 54 on the free end of the actuator housing 43. The thread is designed in such a way that when the drive hood is rotated to open or close the valves 11 and 22, the hood moves. along the actuator in unison with the valve movement, exerting axial pressure on the shaft due to the friction engagement of the pin 45 from the wall 1 of the grooves 46. In order for the valve 22 of the filling head to open only together with the valve 11 of the valve, an annular socket 55 in which pin 45 can rotate.
    Thanks to this method, the axial position of the shaft is determined only by the axial position of the valve 11 in the gate 2, which uncouple the connection between the cap and the shaft.
    An additional feature of this option is a clamping device 52 (FIG. 4), having two
    opposite flat elements 56 with concave semi-circular free edges 57 that move horizontally in guides 58; to hook the ring 9 of the fastener in the groove 59. At a distance from their free edges 57, the flat elements are rotated 90 to form two mutually parallel arms 60. Two eccentric 61, pivotally mounted on horizontal pins 62, one on each side of the body of the filling head 25, have eccentric protrusions 63, on which the shoulders 60 separately rest and are held by special means. The flat elements 56 enter into the groove 59 when the filling head is in the position shown in FIG. 2. The handles 64 (Fig. 2), which are tightly connected to the protrusions 63, allow the eccentrics 61 to be manually rotated in order to bring the shutter and the filling 1 tin together by moving to a position above the center and clamping them firmly during filling. For clarity, the clamping device 52 is omitted in FIG.
    Although this plug-in connection is made for manual control, it is emphasized that it can be easily fully or partially automated, for example, if an electric or pneumatic actuator is provided for the driving cap 44, the device 52 is replaced with a pneumatic clamping device and the sequence control is automatically controlled.
    Various changes may be made to this design. The closure 2, for example, can be molded from plastic without an external screw thread 10, but with an annular groove, into which an additional flange on the fastening element can be firmly inserted, replacing the fastening ring 9. This fastening element may have vertical walls surrounding the closure 2 and serving to direct the filling head 3 to the engagement position with the closure. Clamping device 52. can be replaced with a set of vertical bars with horizontally extending supports and means for rotating the bars to draw them
    supports under the side flange on the side of the bolt 2, and for lifting the rods to bring the bolt and the filling head together. The valve 11 of the bolt may be provided with a dome-shaped head with protruding columns, which enter additional slots in the correspondingly concave head of the valve 22 of the filling head. The sealing lip 13 may be replaced by a pair of vertically spaced horizontal sealing lips, in which case the valve 11
    will be blocked for cleaning in a position in which the space, where the protrusions will be sterilized with steam, to remove any product residues.
    In practice, the joint is installed horizontally rather than vertically, so that the steam outlet is directed downwards to remove any condensate.
    In addition, although all of the foregoing relates to the aseptic filling of containers 1 from a storage tank, this compound can also be used to aseptically empty containers. The conduit 30 in this case is adapted to remove the product from the head 3, and not the dp of supplying the product to the head. Friends and words, tips and
    the sequence of operations remains unchanged.
