Definitions

  • the invention relates to a bag filling machine with an electronic weighing device, which has a force transducer acted upon by a bag chair column, and with a bag chair guide, which consists of two upper and lower parallel bars, which are arranged on both sides of the bag chair column and whose two bearing points are designed as rod ends.
  • Such a bag filling machine is known from DE-PS 27 04 138.
  • links with rod ends for example self-aligning ball bearings
  • certain manufacturing tolerances in the manufacture of the links can be compensated.
  • D a for an electronic scale the displacement of the bag chair is only a few millimeters, is given a sufficiently good approximation to a vertical movement of the bag chair column.
  • wishbones are provided, which engage the sack chair column in the upper and lower area and prevent a possible tilting movement.
  • the wishbones Since the wishbones have a fixed length, they hinder somewhat the vertical movement of the sack chair column, as made possible by the parallel brackets. This can adversely affect the weighing process.
  • the invention is therefore based on the object of designing a sack filling machine of the type mentioned at the outset in such a way that a tilting movement of the sack chair column between the parallel cores is reliably prevented and yet there is no impairment of the vertical movement of the sack chair column.
  • Sack filling machines which are provided for filling valve sacks have a filling tube which can be inserted into the sack valve.
  • the filling tube is regularly inclined downwards, for example by 20 ° with respect to the horizontal. It has been shown that a measurement error occurs during the filling process, during which the weighing process takes place continuously. Studies have shown that this measurement error is due to the fact that the filling material coming from the filling tube hits the side wall of the sack at approximately the angle of the filling tube. This creates a vertical force component that falsifies the weighing result.
  • the parallel bars are ker parallel to an inclined filling tube.
  • the parallel links are also inclined downwards at an angle of 20 °.
  • the force transducer can still be aligned horizontally so that its measuring direction is aligned perpendicular.
  • the force transducer can also be oriented in such a way that its measuring direction is oriented perpendicular to the parallel core, so that in the example mentioned it is tilted 20 ° from the vertical. This leads to the sensor measuring only one weight component, namely the weight multiplied by cos 20 °. To get the exact measurement result, the electronics of the balance must multiply the measurement result by 1 / cos 20 °.
  • a fixed machine frame 1 is shown in broken lines. At the rear end of the machine frame 1 connected to pin 2 are formed as a spherical bearing G elenkkexcellent 3 of upper parallel links 4 and lower parallel links 5 is attached. The other ends of the parallel links are connected to an upper axle 6 or lower axle 7 via corresponding joint heads 3. In the middle of the axes 6, 7, sleeves 8 are arranged, which enclose a bag chair column 9 and hold it firmly.
  • the upper parallel link 4 are connected by a rigid coupling rod 10 and the lower parallel link 5 by a rigid coupling rod 11.
  • the coupling rod 10 or 11 thus forms a rigid frame with the associated parallel link core 4 or 5, which prevents the axes 6, 7 from tilting sideways out of the plane formed by the parallel link 4 or 5. This also prevents the bag chair column 9 from tilting.
  • the parallel links 4,5 are inclined 20 ° downward from the horizontal. This inclination corresponds to the inclination of the filling tube (not shown) of the bag filling machine.
  • this has a rectangular frame 12, the upper cross bar of which is connected to a force transducer 13.
  • the frame 12 is inclined forwards from the vertical by 20 ° so that it is perpendicular to the planes formed by the parallel links 4 and 5, respectively.
  • the force transducer 13 is oriented such that its effective measuring direction is oriented perpendicular to the links 4 and 5 - and thus also perpendicular to the upper crossbar of the frame 12.
  • the force transducer 13 is formed by a bending rod, which is attached to the machine frame 1 parallel to the parallel core 4 or 5.
  • the parallel links 4 and 5 are parallel to the filling tube of the bag filling machine and parallel to the longitudinal axis of the bending rod serving as a force transducer 13.
  • the force transducer 13 does not measure the weight G of the filled bag, but a weight component G cos 20 °.
  • the evaluation electronics is therefore set so that it multiplies the weight measured by the force transducer 13 by the constant factor 1 / cos 20 °. In this way, the correct absolute value is determined by the weighing device.
