Definitions

  • the invention relates to packaging technology and, in particular, to vertical automatic packaging machines with which, starting from a flat band wound on a spool, airtightly filled and sealed containers can be produced.
  • the flat band wound on a spool is first wound around a mandrel or hollow body and welded in the longitudinal direction, the overlapping edges being covered with a fine strip of thermo-weldable material and a tubular structure being created from the band .
  • the bag is filled with sterilized substances (for example UHT milk), the operation being carried out under conditions of complete sterility.
  • sterilized substances for example UHT milk
  • the inside of the bag is sterilized and all the processes of shaping, filling and sealing are carried out completely without contact with the ambient atmosphere, whereby packaging with absolute sterility and maximum guarantee for a long shelf life of the packaged goods is achieved.
  • This type of bag which is very common in the known art, has the disadvantage that it cannot be set up vertically for a single presentation to the consumer. There is currently a tendency to prefer stable packaging with a self-supporting structure. In fact, many flexible bags are equipped with small extra feet to make them stable.
  • filling machines for semi-solid cartons are known in practice and in the international patent specifications, into which sterile milk and other various beverages are introduced. With these horizontal machines, the box is already preformed and is taken from an adjacent storage facility, where it is in a folded and stacked state. In the case of the machines of this type, the carton is sterilized after removal and filled with sterile liquids and then further sealed under aseptic conditions.
  • the task to be solved is to carry out these operations at the same time in order to produce bags with a self-supporting, tensioned structure, starting from packaging material in the form of a flexible band.
  • the novel bag must have a flat bottom and at the same time have the ears which are turned over and fastened to the bottom or to the side parts.
  • the new machine alone must simultaneously produce a bag with a sharp-edged, flat bottom, which can also stand alone if it contains liquid substances, i.e. liquids.
  • the invention is based on a packaging machine which is capable of simultaneously producing bags that stand alone, even when they are empty.
  • the bag into which the goods to be packaged have already been entered (coffee in the present example).
  • the bag is reinforced on the bottom by the strip 4 and by the ears 3, which are each shown in broken lines, while the bag is shown in section.
  • the bag still has the shape of a parallelepiped and the sealing pliers, which are actuated by known devices, for example by parallelogram joints 7, approach the body of the bag, which consists of a flexible band, in a first phase.
  • a cutting tool 8 which will be effective later, is visible;
  • Fig. 21 shows the effect of the twin pliers, which are operated by the parallelogram 7, in the immediate vicinity of the lower end of the tubular part 5.
  • the special arrangement between the upper surface of the pliers 6 and the lower wall of the tubular part 5 leads to the simultaneous formation of the bag bottom and to Protruding ears of the strip 4. The ears 3 are not visible in this figure.
  • the parallelogram 7 is rotated here in such a way that the pliers 6 are shown in their position as close as possible to the lower part of the tubular part 5.
  • the lower bag has not yet fallen down because its upper strip 4 is clamped in the pliers 6.
  • the bag still held by the pliers 6 on the upper strip 4 has already been completed and has its typical wedge-shaped structure and the bottom reinforced by the ears 3 and the lower strip 4, these having already been folded over and applied to the stretched side surfaces of the bag ;
  • FIG. 22 shows the opening of the tongs 6 as a result of the withdrawal of the parallelogram 7, the tongs 6 simultaneously being lowered in order to enable the shaped spoon shown in the subsequent FIG. 23 to take effect.
  • the tense structure of the bag which sinks downwards, can also be seen here. This tension arises from the counterpressure between the upper strip of the bag and the base reinforced by the bending of the lower strip 4 and the ears 3 which have meanwhile been fastened to the side parts;
  • the shaped spoon 11 has a rounded tip 12 which initiates the folding of the strip 4; the strip 4, which rotates around the area with which it is firmly connected to the bottom of the bag, begins its folding rotation under the protection of the rounded tip 12.
  • the edges of the spoon abut 11 against the edges of the triangular ears and lift them off to also start bending the ears.
  • the pliers 6 have opened to rotate the legs of the parallelogram 7 and that the bottom 9 of the spoon does not touch the pliers 6;
  • the bottom and side surfaces of the bag are already fully aligned; the lateral ears 3 and the strip 4 are already prepared to reinforce the bottom and the side surfaces of the bag;
  • 29 further shows the action of the pushing tools 13, which are effective via known mechanisms and which serve to press the ears 3 against the two side parts of the bag.
  • the side ears 3 are firmly connected to the bag by means of gluing tools 13 via glue spots or by means of thermal welding, for example by means of hot air nozzles;
  • the tube part 5 is closed at the upper end in order to keep the sterile liquid in an aseptic state.
  • the liquid for example sterile milk or other liquid substances, is fed into the pipe part 5 via a feed pipe 19 with a liquid level control valve 18.
  • the inner region of the tube part 5 is connected to a container of sterile air via a tube 20.
  • the bag with the strip 4 and the side ears 3, which are already glued to the side of the bag, is inserted into a special hollow body 21 in a parallelepiped shape.
  • the pliers 6, which act against the lower end piece of the closed tubular part 5, let the tabs protrude laterally at the same time as the strip is formed.
  • the pliers 6 also let against the counteraction of the upper end of the body 21, the two other lateral ears analogous to the procedure in the be in the formation Remove the sensitive bag.
  • the bag located inside the hollow body 21 already has two lower ears attached to the side parts, as can be seen from the dashed lines.
  • twin tongs 6 move away after they have separated the two adjoining bags from one another, two identical shaped spoons with the same functions become effective as already described with reference to the preceding figures.
  • the closed and sealed pouch is completed simultaneously by bending and attaching the four ears, two on the side and two on the head;
  • FIG. 39 shows a bag with a tensioned structure and a parallelepiped-shaped design with four ears, which are all already attached to the body of the bag at the same time.
  • the ears are already attached to the side surfaces of the bag and also to the upper end wall.
  • the bag can be reversed and the top wall, i.e. the one with the ears bent upwards can form the floor, i.e. the support surface. It should be emphasized that all operations take place simultaneously at a single station on a single vertical machine;
  • Fig. 40 that it is readily possible to aseptically fill the bags without the use of the parallelepiped-shaped hollow body 21, which then results in a wedge-shaped packaging which, however, has ears which are already bent and attached to the body of the bag.
  • the bag with four ears i.e. the parallelepiped-shaped bag can also be filled with non-liquid substances under non-aseptic conditions and without vacuum.
  • the film or the flexible band can also already be sterilized or covered with a sterile skin to be removed from the packaging.
  • the film can also consist of several layers and also have aluminum foils which enable welding by induction, ultrasound, radio frequency, laser beams or laser plasma.
  • the bag sterilization systems can, of course, be various with or without the use of oxygenated water or ethyl alcohol, but others among the many known methods of sterilization and aseptic packaging can be used.
  • this allows the creation of a single synchronously operating machine which, for example, in a single station produces ten bags with a single elongated sealing pliers, a single elongated spoon with several pairs of folded edges, and the strips and ten pairs of ears in one movement bends and folds, then attaching them all against the bottom or against the side surfaces of the ten bags at the same time by pressure. For example, if the If the production speed were in the range of one working cycle per second, the output of a machine fed by ten bands of flexible material would reach the value of thirty-six thousand packages per hour.
