    The invention relates to a device for feeding a product stream in a packaging machine, which performs filling, transverse sealing and separation of filled bags from a vertical sleeve from a flexible packaging bag. material into which the feeding pipe enters. -
    Disposable bags for milk, juice and other foods are made from flexible. a laminated packaging material consisting generally of layers of fibrous material, thermoplastic and metallic foil. Packaging machines that make bags of this type often use the principle of manufacture, which at the first stage involves the transformation of the web of packaging material into a sealed sleeve with a longitudinal seam that runs down through the machine and continuously, is filled with liquid contents (product) to a predetermined level . Below this level, the conversion of the filled sleeve is carried out using external sealing and shaping devices for a visually closed bag which is completely filled with product during the process. The product is fed into a sleeve of flexible packaging material through a feed tube, the passageway is terminally inside the sleeve and connected to the reservoir for the product installed above. At the lower end of the power

    The pipe is fitted with a valve connected through a mechanical / southern system with a float located around the supply pipe. When the product is fed into the supply pipe and reaches the poplan, the latter rises and closes the valve, causing the product to stop flowing.
    This design provides an inimitable control of the supply of most products using 1 & 1X with relatively good flowability, such as Milk, juice, wine, and
    Dr. five
    However, such a device cannot be used when filling packages with a product with high viscosity, such as cream, ice cream, or oil, since the product 20 cannot be fed into the supply pipe under the force of gravity, but must be injected, as a result of which it can enter for the float and jam it, and in addition, it creates difficulties in .25 cleaning,
    The aim of the invention is to expand. Technological capabilities by packaging highly viscous products .30
    FIG. Figure 1 shows schematically the trajectory of the packing material through the packaging machine during the conversion to filled and sealed bags; in fig. 2 - the device is used to deliver the product.
    Packing machine 1 (Fig. 1) is a conventional type machine in which a web of flexible packaging laminate 2 is fed from a reel to 3. The packaging laminate 2, consisting of layers of paper and thermoplastic and possibly aluminum foil, moves through a series of deflecting rollers 4 upward to the deflecting roller 5, 45 installed at the top of the machine AND. The web is then guided veftikalno downward with simultaneous preoy by expanding it into sleeve 6, which is formed by joining together two longitudinal edges of the web into a sealed npcv ROUTINE seam. Subsequently, the sleeve J3 is sealed into transverse narrow junction with simultaneous pressing of the product with the help of interacting sealing jaws 7, which are under-; one pipe to the other on the opposite side of the pipe and then compressed, as a result of which the internal plastic

    The layers are fused by the heat applied. The operation is carried out continuously with the help of two pairs of sealing jaws 7 (only one pair is shown), which alternately treat the sleeve 6 during its downward movement and release the sleeve 6 during their reverse upward movement. After sealing and separating the material of the sleeve 6 into filled and sealed bags 8, the latter are separated from one another by cuts in the compressed and sealed zones.
    Together with the transverse sealing of the sleeve 6, there is some change in its shape, with the result that the sleeve 6, having an initially circular shape in cross section, acquires a rectangular shape in a cross-section. This is achieved with the aid of the shaping jaws 9 connected together with the sealing lips 7 which compress the sleeve 6 from two sides. After separating the filled and sealed bags 8 from one another, another shaping process is carried out on the filled and sealed bags 8, as a result of which they acquire the desired shape, for example, a parallelepiped.
    In addition, the machine contains rollers and guides for guiding and forming sleeves of flexible packaging material, hot air nozzles for sealing the longitudinal seam, and feed lines and nozzles.
    Somewhat higher than the place where transverse welding is performed using sponges 7, primary converter 10 is located.
     A device for feeding the product includes series-connected primary converter 10, level controller 11 and secondary converter 12 mounted on the feed pipe 13 at some distance from its outlet opening, sealing device 14 and pump 15 with electric motor 16 for feeding the product into sleeve 6 .
    The primary converter 10 consists of a cylindrical sleeve 18 mounted on the supply pipe 13 and connected by a spring 17 to a sealing device 14, the side surface of which is made of metal.

    and two spiral windings 19, located one above the other outside the sleeve 6 of flexible packaging material coaxially with a cylindrical sleeve 18.
    The sealing device 14 and the primary converter 10 are mounted for movement between the upper 20 and lower 21 locking elements located on the supply pipe 13,
    The lower locking element 21 is located slightly above the outlet of the feed pipe 13, and the upper locking element 20 is slightly below the point where the longitudinal seam of the sleeve 6 from the packaging machine ends.


    The bulk of the i / -metal area will be surrounded by spiral windings 19, which, using two coils (not shown) mounted one above the other, adjust the position of sleeve 18 as the difference of signals, which

When the sleeve 18 reaches the setting, it is controlled electrically by means of the spiral windings 19 .. The sealing device 14 contains a disk 22, on the periphery of which there are 25 s directed, downwards the sealing lugs 23, pressed against the inner surface of the sleeve 6. Disk 22 has a central hole, the diameter of which.

    slightly larger than the outer diameter of the feed pipe 13, and the seal 24 is installed in the hole and rests on the outer surface of the feed pipe 13. The space in the sleeve 6 is divided by the sealing device 14 into the lower part, which is filled with product during operation of the machine and the upper part communicating with the ambient atmosphere through the open upper end of the sleeve 6 of the packaging material. .
    Two spiral windings 19, mounted one above the other, are connected to a level 11 regulator (level gauge) of the usual type, which, depending on the vertical position of the cylindrical sleeve 18, sends a signal to the secondary (frequency) converter 12, which regulates the rotation speed of the electric motor 16, connected JQ directly to a gear pump 15, with which the product is fed through a feed tube 13. A pump 15 is co-connected with a reservoir for contents (not shown), and its output line is connected to the upper end of the feed pipes 13.
    The device works as follows. at once.

    This upper end position, the gauge supplies through the secondary transducer 12 (the frequency signal to the motor 16 to reduce the speed of rotation of the pump 15, resulting in a decrease in the supply of product 25 through the feed pipe 13. The packaging machine continues to manufacture and separate the filled and sealed packages 8 the lower end of the sleeve 6, the sealing device 14, and with it the cylindrical sleeve 18 will smoothly move down in the sleeve 6 of the packaging material (partly depending on and between the protrusions 23 of the disk 22, the sleeve wall b, and partly depending on the weight), which leads to a change in the output signal from the spiral windings 19, which through the level gauge and the secondary converter 12 increases the speed of rotation of the electric motor 16, resulting in a flow of product 25 into the sleeve 6 through the feed pipe 13 is again increased, the sealing device 14 is raised and the process is repeated.
    If necessary, the two end positions can be adjusted. However, in order to prevent damage to the elements in the sleeve 6 due to excessive movement, for example due to increases in pressure in the product 25 due to compression and the formation of the lower end of the sleeve 6, the movement of the sealing device 14 and the cylindrical sleeve 18 is limited by two
    Product 25, for example, an oil (at a temperature of about, a discharge pressure of about 3 bar), is pumped from a reservoir 15 (not shown) through a feed pipe 13 to the lower end of sleeve 6 from packaging material, where it rises until it is will come into contact with the sealing device 14 and the latter will not start to rise. The cylindrical sleeve 18 also rises, as a result of which an ever-increasing part of the i / -metal area will be surrounded by spiral windings 19, which, using two coils (not shown) mounted one above the other, adjust the position of the sleeve 18 as the difference of signals
