Definitions

  • the invention relates both to the countries DE, FR, GB and IT and to the countries BE, CH, NL and SE according to the preamble of the associated claims 1 and 2, respectively, to a method and a device for the metered, weight-based filling of a predetermined amount of a flowable, Powdery or finely granulated filling goods in packaging containers, in particular in tubular bag packs or the like.
  • EP-A-0234605 (prior art according to Article 54 (3) and (4) for the countries DE, FR, GB and IT) is one of these Method known, wherein the filling material is introduced into the packaging container gravimetrically by the predetermined quantity of the filling material to be introduced into the packaging container from a first filling supply at intervals, controlled gravimetrically by means of a speed-controlled metering screw into the packaging container and then one of the filled quantity approximately corresponding to the quantity Bottled goods from a second bott llgutborrat is metered to the first bottled goods within a time corresponding to the downtime of the packaging machine, and a device with a speed-controlled, motor-driven discharge screw in a cladding tube, which is flanged to the outlet end of a container containing the bottled goods, the bottled goods container being mounted on load cells, An entry screw controlled in terms of the number of its revolutions is arranged above the filling goods container and the arrangement is assigned a control device, to which the measurement data of the weight load cells
  • the volumetric dosage has the disadvantage of being extremely imprecise, which results in considerable weight differences in the contents of the packs. Wherever greater accuracy is required when portioning the filling goods, it is common to use replenishment systems with a shut-off scale, which, however, cannot be used for tubular bag packaging machines because of the connection of the packaging container to the packaging machine. But even these devices, which are supposed to be able to achieve a relatively high level of accuracy, show that this is ultimately not sufficient in practice because the overfill required by the provisions of the prepackaging regulation reaches a level which leads to considerable losses for the bottler Operation leads. This fact is illustrated by the example given below.
  • the shortage due to filling must not be greater than 15 g. Since experience has shown that the filling device works with a tolerance of ⁇ 20 g, an average minimum weight of the filling quantity of 1,005 g is set for all packs. This means that the overfill is at least 5 g per pack. If, for example, 1.2 million packages are produced in one year, the overfill is at least 6,000 kg per year. If the kilogram is assumed to be DM 20, the overfilling of just 5 g with a 1,000 g package results in a loss of DM 120,000.
  • the invention is based on the object of designing the known method and the device in such a way that the use of load cells with a small measuring range is possible, and of course in compliance with the legal provisions of the prepackaging ordinance, in order to finally overfill the packages as a result of these provisions to reduce a minimum.
  • the drawing shows the device for carrying out the method designed according to the invention using a particularly preferred exemplary embodiment relating to both the device of the claims for the countries DE, FR, GB and IT and the device of the claim for the countries BE, CH, NL and SE .
  • a from a frame, not shown Carried frame 11 serves to support the container 12, which rests with its three claws 13 on load cells 14.
  • An entry screw 23 is arranged above the frame 11, the screw housing 24 of which has an outlet 25 projecting into the filling goods container 12 without any need for guidance.
  • the feed screw housing 24 is connected via a pipe socket 26 to a storage container 27 (not shown in detail) for the filling material.
  • the feed screw 23 is set in rotation by the drive motor 29 via the gear 28.
  • the device described above and shown in FIG. 1 is operated in the manner according to the invention described in more detail below.
  • the quantity of filling material held in the filling material container 12 is kept relatively small and constant so that the weights and weight differences of the device supported on the weight measuring boxes 14 are kept as small as possible. Due to the constant amount in the container 12, the static pressure prevailing at each point is approximately the same and is therefore subject to only minor, negligible fluctuations due to the system. In addition, in the selected embodiment, it can be achieved that external influences, such as e.g. Vibrations, largely suppressed, if not completely avoided. This also has a positive effect on the improvement of the dosing accuracy.
  • the vertical discharge screw 16 in the cladding tube 15 surrounding it is preferably driven by the drive motor 18 in the phase-gated electric motor, the speed of which can be set to a specific value between 0 and 1200 rpm, cyclically, as can be seen in particular from the graph in FIG. 2A is evident.
  • the discharge screw 16 conveys a predetermined quantity of the filling material into the packaging container 39 arranged under the lower mouth 38.
  • the control unit 32 switches off the drive motor 18 via the motor controller 34, as a result of which any further dispensing of filling material does not occur .
  • the drive motor 29 is switched on, as a result of which the feed screw 23 introduces approximately as much filling material into the filling material container 12 as was previously discharged from it.
  • the next quantity of filling material (G2) is now assumed, as can also be seen in a simple manner in FIG. 2A.
  • the discharge is expediently carried out by the discharge screw 16 in two stages. In a first stage, approximately 90 to 95% of the metered quantity of filling material to be dispensed is applied, and in the second stage, with the speed of the discharge screw 16 slowing down, the remaining amount, in order to improve the accuracy in the desired manner in this way as well.

Abstract

Un procédé et un dispositif servent à remplir des récipients d'emballage, en particulier des sachets tubulaires ou similaires, avec des doses à poids prédéterminé d'un matériau fluide, pulvérulent ou finement moulu. L'introduction du matériau de remplissage dans les récipients d'emballage se fait par gravité. A des intervalles, une vis sans fin de dosage (16) commandée par la vitesse de rotation transfère gravimétriquement une quantité prédéterminée du matériau de remplissage d'un premier réservoir (12) au récipient d'emballage (39). Finalement, une quantité de matériau de remplissage à peu près correspondante à la quantité distribuée est amenée d'un deuxième réservoir (27) au premier réservoir (12) de matériau de remplissage pendant une période de temps correspondant à la période d'arrêt de la machine d'emballage.
