    A method and machine for the manufacture of packing containers of the type where a number of packing container blanks are successively converted to packing containers, open at the top, which are filled with contents, shaped and sealed. The packing container blanks are advanced intermittently during the processing and filling between the different stations, which means especially in packing machines with several conveying elements, that the driving unit of the machine will be unevenly loaded and that the working of the machine will be uneven and jerky. To overcome this it is proposed in accordance with the invention, that the driving of the different conveying elements should take place asynchronously in accordance with a similar but mutually offset pattern of movement. The one conveying element (6') will then be substantially at standstill during the advance of the second conveying element (6") and vice versa, as a result of which the driving unit obtains an appreciably more uniform torque curve so that uneven operation and consequent wear and noise can be prevented.

    The invention relates to a method of manufacturing, filling and sealing packages (containers) on two production lines, on each of which packaging containers are advanced intermittently using a single conveyor between different processing stations. The invention also relates to a packaging machine for carrying out this method.
    The purpose of the invention is to reduce energy consumption. cost and increase the reliability of the device.
    A method of manufacturing, filling the product and sealing packages of packaging material on two production lines is that along the devices for making, filling the product and sealing each production line, the packages are moved by means of an individual conveyor, and the movement of the packages by one conveyor (single line conveyor) carried out asynchronously with the movement of packets through another conveyor (conveyor of another line).

    The proposed method is carried out using a packaging machine.
    FIG. 1 shows a car, side view; in fig. 2 - the same, top view; 5 in FIG. 3 - packaging process - carried out on the proposed machine; in fig. And - the cogwheel, scheme.
    The machine consists of a frame 1, which Q contains a horizontal plate 2. Under the plate 2 is located the drive unit of the machine, its electrical system, lubrication system and other conventional
    V
    parts needed for work. Drive-5 Noah unit, in addition to the engine 3, contains a gear wheel 4, which, in addition to
    conversion of the continuous rotation of the engine 3, transmits the movement of the moving parts of the machine. Thus, the 20 gear wheel 4 is connected to a drive shaft 5 located in the center of the machine, which in turn drives two conveyors 6 that run parallel to and located 25 frames above plate 2 on the drive shaft 5. discs 7, from which, by means of a system of levers and tg (not shown), movement is transmitted to a number of processing stations located along each conveyor 6. A vertical transmission element (not shown) also departs from the gear wheel 4, which actuates several The wheels are 8, fixed 35 so that they can rotate on the frame, 1 machine. The drive unit, which for the most part is conventional, also contains additional power shafts for 40 lubrication of oil pumps, compressed air pumps, etc.
    The drive unit is generally located under the slab 2 frames 1 "
    Above the slab 2 of the frame 1 are located d5 transporting elements for blanks of packages (packaging containers) and a number of various devices for shaping, filling or otherwise processing individual packaging containers 5o.
    Packaging containers such as the so-called type of skate roof,
    include a carrier layer of paper, which is coated on both sides with thermoplastic and heat sealed sheets. The blanks are separated by bending lines into various panels for the container body,
    upper and lower parts and laid out flat.
    The machine contains two magazines 9 located outside the frame 1 and intended for receiving lots of several blanks 10 of packing containers (Fig. 3), which are manually or automatically installed in the magazine 9, from where they are successively moved to the lifting unit 11. The lifting unit 11 lifts the individual billet 10 of packaging containers lying flat so that they become tubular in shape and take on a generally square cross-section. With the help of feeding mechanisms 12, the tubular blanks 10 of the packaging containers are then transferred to the mandrels 13, which are currently in line with the feeding mechanisms 12, and the mandrels 13 are fixed on the wheels 8 intended for stepwise rotation. Each wheel 8 with mandrels 13 is usually dual and also interacts with dual feed mechanisms 12. All subsequent processing devices (for filling packages with product, sealing bags) are also dual. When the preform 10 of the packaging container is placed in a predetermined position on the mandrel 13, the wheel 8 rotates one step, with the result that the protruding end of the preform 10 is placed directly opposite the hot air blower 14, which heats the thermoplastic layer of the packaging material to softening temperature. Thereafter, the wheel 8 with the mandrels 13 is rotated one more step, and the heated protrusions of the base of the workpiece 10 are folded together and compressed with simultaneous cooling so that a tight container base is obtained. Upon further rotation of the wheel 8 with the mandrels 13, the packaging containers are placed vertically on top of one or the other of the two conveyors 6 and this completes the processing of the blank 10 for the packaging container in the first part of the machine.
    Two chain conveyors 6, each of which serves to connect all the corresponding devices of one production line, run in the longitudinal direction of the machine parallel to one another and the drive shaft 5 o Each
    The conveyor 6 comprises two endless conveyor chains, provided with carriers, between which there are cavities or compartments, the dimensions of which correspond to the dimensions of the packaging containers. The number of wheels 8 with mandrels 13 can vary as a function of machine dimensions, but each conveyor 6 is associated with one (dual) wheel 8 with mandrels 13 and runs at one end directly below the axis of rotation (parallel to it) of wheel 8 with mandrels 13. From each wheel 8 with mandrels 13, packing con-1 teiners are now transferred to the underlying conveyor 6 by moving vertically down into the free compartment of the conveyor. Immediately after placing the packaging containers in the correct position on the conveyor 6, they are intermittently moved through the flow lines, and the conveyors 6 move the packaging containers step by step to the devices (processing stations) that are located along each conveyor 6. After moving for a certain distance on the conveyor 6, the current packaging container opened in the upper part approaches the first processing station, which is the pre-bending device 15 rhney part, the purpose of which consists in prefolding the top panels of the packing container in the direction of the sealed end position, so that the material to crease lines situated between the panels, softens and facilitated the subsequent completion of the top. After pre-folding the top panel, the packaging containers are in a slightly folded position, but the packaging containers are still open when they approach the next station, which contains the filler 16 and the product tank 17. Fillers, like wheels 8 with mandrels 13, can be collapsed and contain two filling units, each with a metering pump 18 and a filling tube 19. The packaging container to be filled up is lifted up using a device that is not shown when it is located directly under the filling tube 19 until the lower end of the filling tube 19 is

    inside the packaging container and will not get close to its bottom. Then the metering pump 18 is turned on and the required volume of product is fed into the container simultaneously with its vertical movement down to its previous position on the conveyor-6 again. As a result, foam formation is prevented. After filling, the packaging container is moved further by means of a conveyor 6 to the next station, which includes an upper part heater 20, which heats the thermoplastic material of the protrusions of the upper part of the packaging container to weld them with hot air. After heating to the softening temperature of the thermoplastic layer, the packaging container is further moved to the next station, which includes a device 21 for sealing the upper part, which folds together and compresses the heated protrusions of the upper part, so that a tight seal is obtained. Upon completion of the sealing, the packaging container is transferred by means of the conveyor 6 to the dating device 22, which stamps on the top of the packaging container the required date and other markings. Thereafter, the packaging container is ready and can be unloaded from the conveyor 6 of the packaging machine using delivery devices that transfer packaging containers to a conveyor belt that is not shown.
    The machine is driven by a drive unit, the motor 3 of which drives the central drive shaft 5 through rotation of the gear wheel 4, which in turn drives the conveyors 6 and various processing stations. In order to solve problems (uneven torque change curve, jerk operation, jolts, shocks and noise) that negatively affect to a greater or lesser extent packaging machines of this type with several flow lines, various devices of the packaging machine in accordance with the invention is driven asynchronously. Thus, the intermittent advancement of the two conveyors 6 does not occur simultaneously, but in accordance with the shifted type of movement, which essentially means that the first conveyor 6 is in a state of rest when the second conveyor 6 is moving. This asynchronous actuation of the conveying elements 6 is caused automatically by the fact that the processing stations 15,16,20,21 and 22 of one production line are activated alternately with the processing stations 15, 16, 20, 21 and 22 of the second production line and in cycle with intermittent movement of the respective transporters 6. This alternate actuation of different processing stations means significant savings in power and energy, since, in principle, for each pair of processing stations (located one opposite each other) In the respective conveyors, energy can be continuously supplied, since energy is supplied alternately to each station of this pair.In known packaging machines, very large energy was required at each time point, since all stations on both (all) conveyors are activated simultaneously. At the same time, it is possible to significantly reduce the size of the energy source or the driving force, since the stations alternately use a common energy source of the drive. This advantage is particularly noticeable with respect to the upper part heaters 20, which previously required a large amount of hot air at every moment, which, due to the inertia of the system, is also produced between use intervals, and this means a net loss of energy. In the machine, hot air can be distributed alternately between the two heaters of the upper part, so that the energy loss due to the inactive heaters of the upper part can be practically eliminated. Likewise, it is possible to simplify the application
    In fillers 16 by alternately actuating them, so that feed pipe 19 can be used more efficiently and similarly pumps, valves and other parts are smaller.
    The intermittent actuation of the two conveying elements is carried out by means of a gear 4, which has two notches 23, the type of movement of which is similar, but mutually shifted by 180 °. This provides greater accuracy in the alternating movement of two conveyors 6. Two blocks of cams 7 receive through the drive shaft 5 a type of movement appropriately displaced, which by means of a drive through the drive shaft 5 is completely synchronized with the intermittent movement of the corresponding conveyor 6. Intermittent torsional movement of the two wheels 8 the mandrels 13 are also synchronized with the movement of the corresponding conveyor 6 so that, without difficulty, the blanks 10 for the packaging containers are transferred from the mandrels 13 on conveyors 6.
    Since the two conveyors and the elements associated with them are permanently connected to the common source of drive energy in the inactive as well as the active position, the load on the drive motor 3 is leveled, so that the visible peaks that take place on the moment diagram significantly decrease. machines with synchronously driven conveyors. Similarly, the total energy consumption is reduced, since the slowdown of one conveyor will contribute to the simultaneous acceleration of the other conveyor, as a result of which less drive unit with subsequent reduction in power consumption, noise, etc. In machines with two conveyors, the latter are connected to a drive power source with an offset of 180, whereas in the case of several conveyors they can be distributed in a different way.
