Definitions

  • the invention relates to a device for the metered filling of liquid to pasty products and products with lumpy inclusions in packaging containers, with at least one mouthpiece having a filling channel, the outlet opening of which can be blocked by a closure element.
  • closure elements In practice, dosing devices with mouthpieces have become known in which the closure elements are designed in a wide variety of ways. Regardless of their design, these closure elements have the task of forming the lower end of the mouthpieces under which packaging containers, e.g. Cups to be passed on a conveyor belt of a filling machine in time. As soon as a packaging container has come to rest, the closure element releases the outlet opening of the mouthpiece, so that contents can enter the packaging container underneath. After the filling process has ended, the outlet opening is closed again by the closure element, and the conveyor belt advances by another cycle until the next empty packaging container.
  • packaging containers e.g. Cups to be passed on a conveyor belt of a filling machine in time.
  • Mouthpieces with so-called wire cutters are also known for filling very hard products. These wire cutters consist of a wire or a wire bracket that can be moved past below the outlet opening and thus cuts off a product strand. Apart from the fact that such wire cutters are damaged quite often and therefore have to be replaced, they also have the very considerable disadvantage that they only cut off the product stream, but cannot tension it.
  • the invention is based on the object of providing a device of the type mentioned at the outset which enables a precisely defined limitation of the quantity of product to be filled in and an exact closure of the outlet opening after the metering process, without thread or drop formation.
  • the closure element is formed by at least one cutting tape.
  • an exact cutting of product strands is achieved and also an exact shut-off of the outlet opening of the mouthpiece is ensured.
  • a cutting tape which is preferably flexible and is guided in a groove around the outlet opening of the mouthpiece, is characterized by simple and inexpensive production and assembly and also has a long service life. The closing by means of the cutting tape can be carried out so precisely that thread or drop formation is prevented in any case.
  • the groove is arranged in a peg-like and rounded outlet part of the mouthpiece in such a way that the cutting band in the region of the outlet opening of the mouthpiece can be displaced in and opposite to the transport direction of the packaging container of the filling machine.
  • the cutting tape can therefore be moved in the manner of a tongue into the area of the outlet opening, which then seals it off and moves it back again, which then releases the outlet opening.
  • a closure element enables the packaging containers to be filled properly.
  • the flexible cutting tape can be made of different materials, a steel tape has expediently proven to be particularly suitable.
  • Particularly suitable for driving the cutting band is a slide mounted on a slide on a guide of the mouthpiece and connected to the cutting band at its end facing away from the outlet opening.
  • the guide which is preferably designed as a T-slot, can be arranged in a support part of the mouthpiece which adjoins the peg-like outlet part.
  • the latter is made from a housing divided in the axis of symmetry of the T-groove, the two housing halves being detachably connected to one another by screws or the like are connected.
  • a cutting tape can also be provided, which is connected to a carriage at both its free ends and provided with at least one passage window in its central area assigned to the outlet opening is.
  • This passage window has approximately the same dimensions as the cross section of the filling channel, which can have an increasingly larger cross section for easier dispensing of the product to be filled over its length, starting from the inlet opening to the outlet opening of the mouthpiece.
  • a carriage can also be provided with its own cutting tape, which at its free end in the area of the outlet opening can either close or overlap and open the outlet opening.
  • the carriage or carriages can be mechanically driven and at least one can also be spring-loaded, so that if there are two carriages, they are moved alternately in one and the other direction, so that the discharge opening is released or closed by this movement via the cutting band can.
  • a common double-armed actuating lever can be provided for driving the sled, wherein the sled can expediently be provided with link recesses which are open on one side and the double-armed actuating lever can be provided with pins which engage in the link recesses.
  • the drive lever itself can be mounted on a central bearing shaft extending transversely to the direction of movement of the packaging container, at the ends of which a mouthpiece can be arranged, so that two mouthpieces can be opened or closed simultaneously by a common drive device and two cutting tapes.
  • the device suitable for the metered filling of liquid to pasty products and products with lumpy deposits in packaging containers essentially consists of a metering housing 1, which is only indicated by dash-dotted lines, and a mouthpiece 2 arranged below it 2 has a filling channel 3 which, as can be seen from FIG. 2, is rectangular in cross section.
  • the filling channel is at its Inlet opening 4 is made smaller in cross section than at its opposite outlet opening 5.
  • the mouthpiece is formed by two housing halves 6 and 7 which, as can be seen from FIGS.
  • the mouthpiece has an essentially cylindrical fastening part 11, which is followed by a substantially trapezoidal supporting part 12, which in turn merges into a conical, rounded outlet part 13.
  • the lower outlet opening 5 can be closed and released by a flexible cutting tape 14.
  • the cutting belt 14, which is designed, for example, as a steel belt, is provided with a passage window 15 which has essentially the same dimensions as the outlet opening 5.
  • the two free ends of the cutting tape 14 are attached to slides 16, 17 which can be moved up and down in T-grooves 18, 19 arranged in the support part 12.
  • the passage window 15 can be brought into the area of the outlet opening 5 so that the product can flow from the mouthpiece into the packaging container underneath, while in the other case the outlet opening 5 is blocked off by the cutting tape.
  • it is guided in grooves 20 which are arranged in the outlet part 13.
  • the T-grooves 18, 19 are arranged in the support part 12 at an angle of approximately 20 degrees to the filling axis.
  • a blind bore 21 is also provided in one housing half 7, the meaning of which is explained in more detail below.
  • FIGS. 4 to 6 show two mouthpieces 2 arranged parallel to one another and connected to one another via a common bearing shaft 22 are connected.
  • This bearing shaft is used to mount a double-armed actuating lever 23, each associated with a mouthpiece 2, one arm 24 of which is connected via a bolt 25 to a link recess 26 of one carriage 16 and the other arm 27 to a correspondingly configured pin 28 and a similar link recess 29 of the other Carriage 17 cooperates.
  • the carriages 16, 17 are moved back and forth in the T-slots 18, 19 via the bolts 25, 28, and the cutting band (not shown in FIG. 4) is thereby moved along the outlet opening 5 of the mouthpiece 2.
  • the bearing shaft 22 is mounted in the mutually facing housing halves 7 and 6 of one and the other mouthpiece 2. As can be seen in the right-hand mouthpiece 2 in FIG. 6, the bearing shaft 22 is mounted in a bushing 29 which in turn is seated in the blind bore 21 of the mouthpiece 2. The corresponding storage of the mouthpiece 2 shown on the left is not visible.
  • a locking lever 31 which can be screwed to the associated actuating lever 23, sits in the area of the other, i.e. the left mouthpiece 2, in the area of the actuating lever 23, a drive lever 32, which is also on the Bearing shaft 22 is held clamped and is provided with a pin 33 which is operatively connected to a slot guide 34 of a linkage 35.
  • the entire drive of the actuating mechanism can be carried out via this.
  • each sled 16, 17 its own cutting tape, which is located in the area of its free ends at the level of the outlet opening 5 and there either butt or meet overlapping, so that opening and closing of the outlet opening 5 is also possible in this way.
  • the cutting tape can also be equipped with two passage windows for a half-speed operation.
  • the cutting tape can also be made from a flexible plastic or from other suitable materials. In the case of a simple embodiment, it can also be considered in principle to provide only one slide with a tongue-like cutting band.
  • the housing does not need to consist of two housing halves; rather, a recess can be eroded into a one-piece housing, into which an insert left with a guide groove for the cutting tape can be inserted.
