    The device 1 can also be a device of any other already known construction. In addition, the device 1 must work with the packaging material in the form of a continuous tape 2, which is continuously transformed into the tube 7, after which the tube 7 is filled with the contents and subjected to molding.
    The front of the device 1 (Fig. 2) comprises a device for processing and shaping the tube 7, which passes vertically downwards through the device 1. In the lower part of the device t, an actuator 1A is installed, containing an electric motor and a gearbox and a main drive shaft 15 which rotates, which passes horizontally through device 1 and on which many radial cams are installed. For the proposed device, mainly the first radial cam 16 and the second radial cam 17 are important.
    Device 1 (Figures 2 and 3) contains left and right halves, which are identical to one another, but arranged so that they are a mirror image of one another. The opposite halves of the device 1 are designed and work in the same way. Thus, there are two pairs of cams 16 and 17, and the layout on both sides of the actuator 1A is such that the first cam 16 (FIG. 2) is located closest to the actuator 14, and the second cam 1, has a similarly shaped belt in turn, by means of another spring with another arm of the Rocker arm 28, With the aid of springs 29 and rocker arm 28, the toothed belt 25 creates, by means of pulleys on the upper arm 18 and fastening on the lower arm 19, the force of the strut 17 is referred further to the end of the arm a wand that does not have both levers in the flood shaft 15.
    one to the other, as a result of which they are constantly supported by cams 16 and 17, respectively. The various movements of the two levers 18 15 and 19 are perceived by the springs 29 and the bark1 ;; scrapping 28, which, due to the alternate operation of the two halves of the device-. station 1 makes a swinging movement. Toothed belt 25 together with shkivymi 26 and 27 forms a traction element.
    Above and below the cams 16 and 17 are installed driving levers 18 and 19, which are supported by means of follower rollers on the cams 16 and 17, respectively. The lever 18 is located above the cam 16 and is fixed at one end rotatably around an axis parallel to the main drive shaft 15. The free end of the lever 18 is connected by a lever transmission 20 to the first drive bar 21, which passes through the device 1 vertically it is in turn connected to a device 22 for forming transverse seams.
    The lever 19 resting on the cam 17, like the lever 18, is fixed at one end rotatably around an axis parallel to the main shaft 15, However, the lever 19 is located below the cam 17 on which it is supported with the possibility of free rotation. The front end (Fig, 2, left) of the lever 19, like the lever -18, is connected by a lever transmission 23 with

    1, there is a similar undersized belt, which in turn is connected via another spring to the other arm of the Rocker arm 28. With the help of springs 29 and the rocker arm 28, the toothed belt 25 creates a pulley on the upper arm 18 and the fastening on the lower arm 19 which is not both levers in
    one to the other, as a result of which they are constantly supported by cams 16 and 17, respectively. The various movements of the two levers 18 and 19 are perceived by the springs 29 and the bark1 ;; scrapping 28, which, due to the alternate operation of the two halves of the device 1, makes a swinging motion. Toothed belt 25 together with shkivymi 26 and 27 forms a traction element.
    The method of removing two levers 18 and 19 in contact with the cams 16 and 17, respectively, by means of spring-loaded elements 25, capable of absorbing effort, is very economical from the point of view of the occupied space and is safe in operation. In the immediate vicinity of the cams and drive is an element that takes tensile force, and the springs 29 can be placed in some other suitable place of the device 1; the two halves of the device 1, which work alternately, can be connected by means of toothed belts with the same spring assembly, if it is designed as a rocker arm 28, this
    , the second drive shaft 24, the passage - provides additional savings simple through the device 1 vertically.
    with the simultaneous use of springs to reduce the size of the spring 29 by about 50%, while due to the reduced length of the springs, their performance is improved,
    Tia a short distance from the front ends of the two levers 18 and 19 passes a toothed belt or some other element 25 capable of perceiving the tensile force between the fastening on the lower lever 19 and the tongue 26, fastening rotatably on the upper lever 18, From a pulley 26 serving as a guide pin for the toothed belt 25, the belt goes through the other: the pin 27 mounted on the upper arm 18 in the direction to one of the ends of the rocker arm 28, to which it is connected by means of the tension coil spring 29. On the opposite mirrored side, the additional savings are getting simple.

    with the simultaneous possibility of reducing (due to the alternate use of springs) the dimensions of the springs 29 by about 50%, while due to the reduced length of the springs, their performance is improved,
    Two levers 18 and 19 are connected with the help of lever gears 20 and 23, respectively, with vertical drive rods 21 and 24, respectively. The drive rods 21 and 24 are mounted with the possibility of moving in the vertical direction along the package T. In the slide bearings 30 fixed in the frame of the device 1, the lever gears 20 and 23 are adapted to transfer the movement of the levers 18 and 19 to the drive rods 21 without lateral action. and 24,
    This feature is provided by multi-swivel linkages.
    Two mirror-mounted and alternately devices: 22 for forming transverse seams of the device 1 contain welding jaws 8 and the supporting jaws 9 Each with method 22 for forming transverse seams contains about, 31, which on one side are fixed coeffix with the first drive gear. by barbell 21 i and can be moved by means of I of this bar in the upward direction and i SHHSs The second actuator bar 24 passes through the yoke 31 without being directly; its connection with that; and the other side of the driving rods 21, and 24 the yoke 31 has supported
    axes 32 for two welding X jaws 8,: Axes 32 are at right angles to: drive rods 21 and 24 parallel: main drive shaft 15 machines} Welding jaws 8 can rotate with a non-working diluted (unlocked) position and the working (closed) position, in which the jaws 8 run parallel to the driving rods 21 and 24 (Fig. "4"). The rotation of the welding jaws 8 located in the casing 31 directly opposite one another is carried out by means of a bracket 33. From the bracket 33, pull back down the 345 connecting rod from the bottom of the jaw jaw 8 to the side each other. As a result of this design, the welding jaws 8 remain immobile, while the first and second y and the rods 21 and 24, respectively, move in the same way, but in the case of how. the differences in the movement of the two driving rods 21 and 24, the bracket 33 is moved vertically up or down relative to the casing 31J, as a result of which the welding lips 8 rotate around the supporting axles 32 "
    On the upper parts of the two welding jaws 8, a side-by-side console 36, arranged directly against one another on both sides of the tube 7 of packaging material, passing in a vertical direction through the device 1, is provided opposite to one another on the side sides of the consoles 36 welding plugs .37 (Fig 4) 5 extending in relation to the tube 7 and the transverse direction
    and made with the possibility of squeezing the tube 7 in the transverse zone at the working position of the welding jaws 8. One of the two interacting welding tires 37 has two electrical conductors located at a small distance from each other, which provide heating of the thermoplastic layers of the packaging material tube welding in transverse zones located at some distance from one another Welding tires 37 are connected by a known
    5 with a suitable current source
    A cutting device (not shown) acts between the two conductors of the welding rail 37, which during welding cuts the tube 7 of the forging material between two transverse welds. The cutting device has a known construction and operates from a hydraulic drive (not shown). Besides,
    5 there are volume flaps (not shown) which have an influence on the formation of 13 n packages mechanically controlled by means of pushers installed in the welding jaws 8, which act through the control lever 38, the cam 39 fixed on the frame of the device 1, with vertical return -accessive movement of welding jaws about
    g On either side of the welding rails 37 of the welding jaws 8, hook-shaped elements 40 and 41 are mounted, which, in the working position of the welding jaws 8, are engaged with each other and
    0, the time for squeezing and welding the tube provides the necessary strong pressure of the welding rails 37 against each other. One welding sponge 8 has a fixedly attached hook-shaped element 40 extending from it at a right angle, and the opposite welding sponge 8 is equipped with a hook-shaped element 41, which can be rotated around an axis passing parallel to the main shaft 15 of the device 1 and in addition, a reciprocating motion can be communicated to it by means of a power cylinder 42 located in the welding sponge. The rotation of the hook element 41 in the vertical direction is provided by means of a cam 43 extending laterally from a bracket 33 mounted on a drive rod 24.
    The connection between the rabbit 33 and the welding sponge 8 through t g 34 and consoles 35 provides such a transmission that the movement of the driving rod Vgi 24 upward relative to the yoke 31
     causes not only dilution of the welding jaws 8 from the working position to the non-working one, but also disengagement by means of the cam 43 of the hooked element or one from another by means of the moment 41 with interacting with it. pushes 46 for adjusting the volume of the hook-shaped element 40. When the drive rod 24 is moving relative to the yoke 31, a rotation takes place
    welding jaws 8 to the opposite device 15 1. From the roll, the tape 2 is pro-side, i.e. from the diluted position in a whole row of reversible and ki (figure 4), in a reduced or working position (figure 5). In this case, the cam 43 lifts the hook-shaped element 41, so that it can be a non-folding of the fold lines or imprinted and preventively linked to the hook-like pattern on the tape 2 by the relative element 40. After completion of the processing operations, the adhesion is carried out force action in the device 1. Part of the operations performed in the cylinder 42, as a result of which the hook device 1 operation is a traditionally shaped element 41, non-ony operations, such as installing a lot back, i.e. into the welding sponge of the devices for opening, printing-8, thereby providing the required force of compression between the two welding- ,. 37 tires. The action of forceful jaws 9 determines the shape of the finished bag 13 and, therefore, also its volume. Thus, the volume of the package keta 13 can be adjusted by lateral displacement of the cams 45, which are suspended from the frame of the device 1, can be rotated and can be moved towards each other.
    forging material supplied in the form of a roll, which is mounted on the roll holder 3 at the rear
    direction of the rollers 4 and through the device 5 for fixing the match, which ensures the correct singing of the date and the formation and length of the finished packaging containers. Reaching the front top of the device 1
    lindra 42 is maintained for all-30 (Fig. 1, right), tape 2 goes on
    vertically downward, while using the sleeve 6 it is turned into a tube 7 with overlapping longitudinal edges. Two longitudinal edges Tg are welded by means of a welding device located on the sleeve 6, as a result of which tube 7 is obtained with a completely impermeable for the fluid weld. The welding process cutting and cutting are only stopped immediately before starting the welding jaws 8 to the non-working position.
    Vppe welding tires 37 welding sponges 8 are located previously mentioned formazhie sponge 9. The cross section of the formwork dih sponges 9 has a U-shaped. form and together these sponges 9 form
    The rectangular channel, the inner stretched tube 7 then goes further, the measures of which correspond to the outer one downwards, to that part of the device 1, where the dimensions of the finished package 13. The two piping 7 are processed and prepared from the kneading jaws 9 are suspended with possible separate filled packing tyu rotations around the axis, located-capacity. Pass a pair of Bbmie interacting welding rails 37 of the guide rollers 47, which is located and runs parallel to them. On the ends of the forming jaws 9 that are at the same level with the surface of it, they protrude laterally to the axis with the direction of the rollers 44, which, when the holder 31 moves down, come into contact with the cam 45 attached to the frame of the device 1 and the forming jaws 9 while they do not abut one to the other on both sides of the tube 7, the Forming jaws 9 are equipped with springs pushing them towards the gg drive rod 21 to the position in the SRI from the tube 7, so that when returning is an upper dead center (fig.Z, left ), the movement of the cage 31 upwards will be in the given diluted Assumption. The mutual position of the molded liquid inside the tube 7, the tube 7 comes into contact with one of the two devices 22 to form transverse joints, which alternately process the tube. One of the devices 22 for forming the transverse seams, after it has been moved by the first
    squeezes the tube 7 in the transverse zone by means of welding tires 37 welding jaws 8. Moving welding

    The jaws 9 determine the shape of the finished bag 13 and, therefore, also its volume. Thus, the volume of the package 13 can be adjusted by lateral displacement of the cams 45, which are suspended from the frame of the device 1 and can be rotated towards each other.
    or one from the other by means of handwheels 46 for adjusting the volume of the pack

    devices 1. From the roll, the tape 2 passes through a whole number of reversible and folding lines or printed patterns on the tape 2 with respect to the processing operations carried out in the device 1. Part of the operations performed in the device 1 is the traditional direction of the rollers 4 and through a device 5 for fixing a match, which ensures the correct peon operations, such as the installation of devices for opening, printing
    date and molding and cutting of finished packaging containers. Reaching the front top of the device 1
    The molded tube 7 then goes further down to that part of the device 1, where the tube 7 is processed and receive from it individual filled packaging containers. Pass a pair of interacting guide rollers 47 located flush with the surface of the drive rod 21 to the position at the top dead center (FIG. 3, left),
    A liquid column inside the tube 7, the tube 7 comes into contact with one of the two devices 22 to form transverse seams, which alternately process the tube. One of the devices 22 for forming the transverse seams, after it has been moved by the first
    The connected tube 7 then goes further down to that part of the device 1, where the cabin 7 is processed and obtained from its individual filled packaging containers. Pass a pair of interacting guide rollers 47, which are flush with the surface of the drive rod 21, to the position at the top dead center (FIG. 3, left),
    squeezes the tube 7 in the transverse zone by means of welding tires 37 welding jaws 8. Moving welding
    jaws 8 in the vertical direction are carried out using the first drive rod 21, which is rigidly connected to the yoke 31 and gives it a reciprocating movement in the vertical direction, which allows welding jaws B and other parts connected to the yoke 31 to move. 24 welding jaws 8 pivot the movement of the turn between their open (divorced) extreme position and collapsed working positions (Fig. 4), since the drive-15 does not. The rigid hooked force 24 is connected to the welding sponge ipi 8 by means of a bracket 33, tons of grams and consoles 35 extending from the spike. of the internal jaws 8, when the drive pulleys 21 and 24 move differently than the koBO, the transverse movement of the turn is reported to the welding jaws B. When a second driving rod 24 is received, a downwardly-rotated movement relative to 20
    The elements 40 and 41 are supported during the movement of the casing 31 downward so that the welding jaws 8 are pressed against each other with a predetermined contact pressure for a certain part of the time they are in the closed position. This ensures complete removal of the contents found in the weld zone, and at the same time promotes good contact between the welded surfaces of the laminate and satisfactory heat transfer.
    In the first drive rod 21, when the molding unit 22 is at the top dead center, the welding jaws 8 are moved from the idle position IB to the working one, while the rods 34 rotate the arms 35 in the downward direction until the welding tires 37 are both The sides of the tube 7 do not fit one another.
    The rotation of the welding jaws 8 is caused by the fact that the second drive rod 24 is connected to the welding jaws 8,

    drive rod 21, reciprocating movement, but the imposed and this movement is similar reciprocating 40 translational movement. The resulting difference in movement between the two driving rods 21 and 24 adjusts the lateral movement of the welding jaws 8 so that, in the continuation of most of their downward movement, they are in a reduced working position, and in the continuation of a larger part of their upward movement - in a diluted non-working position.
    When turning the welding jaws 8 into the working position, fixed on the bracket 33 to the cam 43 (described earlier) lifts the hook-shaped element 41, as a result of which, when the jaws are in the working position, it engages with the hook-like element 40. Immediately after adhesion by supplying hydraulic fluid at

    The power cylinder 42 is connected to the hook-like element 41, as a result of which the hook-like element 41 is pulled back, i.e. into the welding sponge 8, which ensures the creation of a predetermined exact contact pressure between the two welding tires 37. Thus,
    the relatively high pressure required is completely perceived by the hook-shaped elements 40 and 41, which greatly relieves the welding jaws 8 and their fastening elements. Hooverly force hook-shaped

    The elements 40 and 41 are supported during the movement of the casing 31 downward so that the welding jaws 8 are pressed against each other with a predetermined contact pressure for a certain part of the time they are in the closed position. This ensures complete removal of the contents found in the weld zone, and at the same time promotes good contact between the welded surfaces of the laminate and satisfactory heat transfer.
    After the yoke 31 has left the top dead center, the forming jaws 9 with their guides to the cimi rollers 44 enter the cam 45, which causes the molding of the jaw 9 to move, overcoming the action of their rod, resulting in their fitting to one another and transforming the part of the sponge 7 between them in such a way that it takes a rectangular shape in cross section corresponding to the required cross section shape of the package 13. The position of the forming jaws 9 and the squeezing force can be adjusted by lateral displacement of the cups chkov 45, 45 is carried with emogo handwheel 46 to adjust the volume placed in the upper jaw 45 tsochke suspension.
    After the first actuating rod 21 moves the yoke 31 some distance down, the control lever 38 of the volumetric flap actuator (not shown) comes into contact with the cam 39 fixed on the frame, which causes the volumetric flap to move to the desired position . At the same time, the hydraulic cylinder of the cutting device is activated, which cuts the material in the compressed zone between the two welded

    weld seams obtained using welding tires 37.
    At the same time, the insertable fixture 22 for the formation of transverse .5 river seams moves downward,
    Forward and welding the tube 7, the same device 22, which is mirrored opposite to it, moves upwards. Due to the corresponding positional communication between the two driving rods 21 and 24, the welding jaws 8 are in the extended position, so that the arms 36 of the welding jaws 8 can freely pass from the outer side of the operating arms 36 in opposite device 22, which at this time is moving down.
    When the described tool 22 for forming cross seams comes to the bottom dead center, the flow of hydraulic fluid to the power cylinder 42 is stopped, resulting in the effect of the tension force of the hook-like element 41 and the squeezing force between the two welding tires 37 is reduced. As a result of driving the second driving rod 24 and moving it upwards relative to the first driving drive 21 of the bracket 33 and the cam 43 attached to it raise, which ensures the release of the hook-shaped s elements 40 and 41 with one another at the beginning of communication dilutions arched jaws 8 from the operating position to the inoperative. At the same time, the guide rollers 44 of the forming jaws 9 come off from the lower end of the cam 45, as a result of which the forming jaw 9 is moved by their springs to the extended position. After the welding sponges 8 have reached the diluted working position, the relative movement between the driving rods 2t and 24 stops and immediately begins to move them upwards, which causes the upward movement of the fixture 22 from the welded h with the sponges 8 in the diluted position. The consoles 36 can pass unimpeded by moving downwardly operating consoles 36 in the opposite molding station 22.

    In the course of the operation of the device 1, the described procedure is repeated continuously, with the result that the two molding units 22 are alternately processed
    and pull the tube 7 forward. When the welding jaws 8 at the end of the working stroke of the molding unit 22 crack and release the tube, the newly formed preform 10 of the packaging container under its own weight falls into the final bending device 11 where the corners of the pillow bent are bent , resulting in packages 13 in the form of a parallelepiped.
    The design of welding tires 37 can be changed depending on the type of packaging material used. Typically, a laminated packaging material is used that contains layers of fibrous material, usually paper, and thermoplastic outer layers. When using this material, the welding busbars 37 contain wires with high ohmic resistance, which during welding are connected to a current source. In the manufacture of aseptic packaging units, i.e. packaging containers for sterilized contents that are capable of long-term storage, use laminated packaging material, which in addition to layers of paper and thermoplastic also contains layers of metal foil. If such material is used, the welding busbars 37 may contain an electrical conductor in the working surface, which may be connected to an alternating current source. During welding, in the metal foil of the packaging laminate, a magnetic field is created directly opposite the welding bars. Due to losses in aluminum foil, this magnetic field heats the foil and the adjacent layer of thermoplastic, as a result of which they are welded to one another.
    The proposed device makes it possible to process within a very limited space the processing of a tube of packaging material filled with contents. Due to the absence of external links for the transfer of energy and movement to the device for the formation of cross seams, the design of this device can be made very compact.
    The absence of a complex lever mechanism in the formation zone is an additional important advantage, especially in aseptic machines5, since the necessary and frequent operations of washing and cleaning the device for the formation of transverse seams can be achieved without affecting the means of driving and under the horn bars and their lubrication points
    Since the entire drive is outside the so-called stripe area, this ensures a long service life of the drive and low consumption of lubricant.
    Due to the use of vertical drive rods, both for controlling the movement of the elements of the device for forming the transverse joints and as rods for transmitting movements, the design is particularly simple and safe to operate compared to known devices.
