Definitions

  • the invention relates to a filling device for metering liquid to slightly pasty filling material into cups of small dimensions which are formed on a film strand and arranged in a dense grid arrangement, according to the preamble of the main claim.
  • Such filling devices are well known and in use, so that no special printed evidence is required in this regard.
  • these are equipped with a large number of small filling pumps, the individual pistons of these filling pumps generally being actuated by a common drive.
  • Under the filling pump rows are each provided for a row of rotary valves with corresponding filling material guide channels, which are designed so that filling material can be sucked in from the respective piston on the one hand, and filling material can be dosed out after the rotary valve has been moved, by filling mouthpieces arranged under the valve block.
  • the invention is accordingly based on the object of improving a filling device, starting from the type mentioned at the outset, in such a way that, with the least possible equipment wall, ie with low manufacturing and assembly costs with high filling accuracy in a confined space and without filling pumps, the liquid to slightly pasty filling material can be metered into the cup.
  • the apparatus complexity of the device is reduced to essentially three parts, namely the reservoir, the valve block, which at the same time forms the bottom of the reservoir, and the control slide arranged in the valve block. Since there are no more filling pumps and the filling material flows directly to the control spool or the valve block, the control spool no longer requires complicated filling material channels. However, in order to ensure the filling accuracy, the prerequisite for this is that the same filling level is always guaranteed in the filling material storage container. For this reason, it is also essential that the storage container is equipped with a level probe, which is connected via a controller to the filling supply pump arranged at the filling supply connection of the storage container.
  • Level controls of this type are generally known (see, for example, US Pat. No. 4,437,497), but in the present context they serve for the most exact possible dosing, ie the level probe ensures a constant static pressure over all filling mouthpieces.
  • DE-A-38 03 677 it is known from DE-A-38 03 677 to arrange the mass supply directly via a valve block, namely in the form of a multiply structured screw housing with paired vertical screws and a horizontal distributor screw, with the aid of which the filling material is mechanically positively conveyed, the valve block and so that filling mouthpieces are fed. Similar conditions exist for a filling device according to US-A-3 658 212. With these known metering devices, a constant one plays Pressure above the filling openings does not matter, since the filling material is also forced out by mechanical means.
  • the filling material supply channels leading to the control slide are provided with funnel-shaped extensions towards the interior of the storage container, which are provided in particular when slightly pasty filling material is to be metered off with such a device. To be on the safe side and in consideration of the level of product to be maintained in the storage container, this can be provided with a product overflow at the specified level.
  • control slide The cyclic actuation of the control slide is carried out by small pneumatic or electromechanical drives, which are advantageously provided with an adjustable timer, so that the respective quantity of product can be metered in depending on the cup size only via a timed actuation of the control slide.
  • the control slides are advantageously designed in the simplest manner in the form of a rod with a circular cross section, the sections of the product passages being designed as sections with a reduced diameter.
  • the device Due to the simple design of the filling device, it is advantageously also readily possible to design the device such that the interior of the storage container is divided into at least two chambers or the storage container is formed at least in two parts, the associated control slide being divided accordingly and the control slide parts being attached to each Free side of the valve block arranged drives are provided.
  • the filling device consists of a valve block 2 arranged above the film passage with the grid arrangement of the cups 18 in the film band 19 corresponding arrangement of filling mouthpieces 17 and also of a filling material container 1 connected to the filling mouthpieces 17. It is essential for such a filling device, and how Fig. 2 shows that the filling supply port 8 provided filling Good storage container 1 is arranged directly on the valve block 2, which forms the bottom of the storage container 1, in which a pneumatically or electromechanically actuated control valve 5 provided with filling material passages 4 is mounted for the at least one filling nozzle row 3, and furthermore in the storage container 1 a level probe 6 is arranged, which is connected via a controller 7 to the filling supply pump 9 arranged on the filling supply connection 8.
  • the filling material feed channels 10 leading to the control slide 5 to the interior 11 of the storage container 1 are provided with funnel-shaped extensions 12.
  • the storage container 1 is equipped at a predetermined fill level with a filler overflow 13, which prevents with certainty that the fill can rise higher than desired above the fill level that must always be maintained, since the fill pressure which always has to be maintained depends on this fill level, which in turn is decisive is for the amount to be metered in, in the respective time period in which the product passages 4 are in the open position.
  • the drive 14 of the control slide 5 is provided with an adjustable timer 15.
  • the control slide 5 can either, as shown, be equipped with individual drives 14, but it is also possible to provide a drive 14 for a plurality of control slide 5, which actuates all the control slide 5 simultaneously via a traverse.
  • control slides are advantageous and in the simplest form in the form of a rod with a circular cross section, the sections of the product passages 4 being designed as sections with a reduced diameter, as can also be seen in FIG. 2.
  • FIGS. 3, 4 represent special embodiments insofar as the interior 11 of the storage container 1 according to FIG. 3 is divided into two chambers 16, with the associated control slide 5 being divided accordingly and the control slide parts 5 'with each free side the valve block 2 arranged drives 14 'are provided.
  • the storage container 2 is divided into four chambers 16 according to the same principle. Such an outline can be done either by installing appropriate partitions 18; but it is also possible to arrange two or four separate storage containers on the valve block 2. Such a design makes it possible to fill different products or quantities in a row or in different beaker fields.
