Definitions

  • the invention relates to a method for filling containers, in particular sacks, with pourable materials, wherein the container is attached to an opening with a filling device, the pourable material is fed from a reservoir of the filling device and is introduced therefrom into the container.
  • the invention relates to a system for filling containers, in particular valve bags, with pourable materials.
  • the system comprises at least one filling device with which the container, the pourable material is supplied and to which the container is received. Furthermore, a conveying member for transporting material through the filling device is provided in the container.
  • a removal device for removing the filled container from the filling device is provided. Furthermore, the removed container can be automatically transported to a further processing position.
  • Bulk materials such as u. a. Building materials or chemicals in granular or powder form are filled into containers in containers in the form of sacks, in particular in valve sacks. The sealed valve bags are then transported to the consumer.
  • the material is mixed with the filling of the valve bags in the air to give the material the necessary bulk or flowability.
  • venting devices are provided in order to allow a pressure reduction from a filled valve bag. These can be designed either in the form of evenly distributed or unevenly distributed over the outer surface or in particular in the seam region of the valve bag, only permeable to air outlet openings.
  • the pressure reduction is not fast enough, so that in the valve bag during filling itself and also after the end of the filling usually still there is an overpressure. This overpressure would result in the direct removal of the valve bag directly after the filling process to a significant leakage of the filled material from the bag, even if a self-closing valve bag is used, which automatically seals the valve by the material present in the interior substantially.
  • a significant leakage of material during the decrease has the consequence that the effective mass of the filled valve bag deviates from the nominal mass.
  • a material leakage can lead to a very significant contamination of the system and its surroundings.
  • a valve bag is left after completion of the filling process for a certain residence time at the filling pipe in the system.
  • the residence time is calculated so that at its end the pressure inside the valve bag has decreased so much that when removing the valve bag from the filling tube no material material leakage occurs more.
  • a disadvantage of the known method is that the throughput drops, as overfilling over the nominal weight and a subsequent venting takes place with material removal. Since the throughput of bags is a significant purchase criterion, the known device and its use leads only to low filling rates. If the suction of the additionally filled material is active on applying a negative pressure, also increase the cost of equipment and operating costs.
  • the invention solves this problem by controlling the pressure p prevailing in the container and, during the filling of the container, controlling at least one filling parameter as a function of the pressure p prevailing in the container in order to ensure effective processing of the container.
  • the method according to claim 1 is used for processing containers, in particular sacks and preferably valve sacks.
  • the container is attached to an opening with a filling device and filled with pourable materials.
  • the pourable material is supplied from a reservoir of the filling device and introduced by means of a conveying member into the container, while a representative measure of the pressure prevailing in the container is measured.
  • at least one filling parameter e.g. the air supply, controlled in response to the prevailing pressure in the container.
  • control device which detects the pressure prevailing in the container by means of a pressure sensor of a measuring device internal pressure and during the filling of the material in the container at least one filling parameter of the filling process, in particular the air supply, depending on the in the container prevailing pressure p or internal pressure controls.
  • the system according to the invention according to claim 14 is a system for processing containers, in particular valve bags.
  • the system contains a filling tube for receiving the container.
  • the container can be fixed with an opening on the filling tube and filled with pourable materials through the filling tube.
  • a conveying member is provided for transporting material through the filling tube into the container.
  • the system is characterized by a control device which detects by means of a pressure sensor of a measuring device the pressure prevailing in the container during filling internal pressure and the filling of the material in the container at least one filling parameter of the filling process, in particular the air supply, depending on the prevailing in the container Pressure p controls.
  • An advantage is the effective processing of the containers, which leads to a high clock rate.
  • By controlling one or more filling parameters as a function of the prevailing internal pressure a short filling time is achieved, while at the same time allowing a small waiting time until the container is taken off.
  • the filling parameters are controlled according to the invention such that both the actual filling process and the subsequent waiting time for the pressure reduction are optimized as a whole.
  • a bulk material which lasts for days or weeks in a silo, a lower proportion of air than freshly filled in the silo products.
  • a product that has already been filled in the storage container or in the silo for a certain supply air flow has optimum filling properties, while a product freshly filled into the silo requires less supply air for optimal filling.
  • Another filling parameter for setting and controlling the filling process is in particular the conveying speed of the conveying member. If the internal pressure in the container increases too much, the conveying speed of the conveying member can be reduced.
  • the current weight of the container to be filled or the already filled amount of material for controlling the filling process is preferably taken into account.
  • the processing of the container basically also includes the removal of the container from the filling device or the filling tube.
  • a closure of the container may be provided.
  • admixing air In a packing machine, there are several different locations for admixing air. In addition to the admixture of air on or before the conveying member and the admixture of air at or in the filling tube is common. In a further development, this proportion of air can be controlled as a function of the measured pressure p and / or of the current weight in order to obtain a good or even optimum flow behavior in the filling tube.
  • the conveying element is designed as a filling turbine or as a screw conveyor, its conveying speed is controlled in particular also in dependence on the pressure p measured in the container.
  • the conveying air is controlled in particular as a function of the measured pressure p.
  • a conveying member preferably also a pump is used, the pump stroke and / or pump frequency is controlled.
  • a control of the conveying member also takes place in dependence on the weight of the already filled into the container product.
  • a control of the metering position of a metering device takes place not only as a function of the product weight being filled, but also as a function of the pressure p measured or determined in the container.
  • the delivery of the conveying member can also be stopped when the pressure p in the container exceeds a predetermined level. After a corresponding pressure drop, the production is then increased again in stages or steplessly.
  • the preferably provided between the filling tube and container Blähmanschette is inflated only when the pressure p in the container exceeds a predetermined characteristic value. Before inflation, the air can escape through the gap, which already causes a lower overpressure during filling. However, if the overpressure exceeds a certain level, material filled in the container may also undesirably be discharged through the gap again. Preferably, the pressure in the Blähmanschette therefore only reduced when the pressure p in the container falls below a predetermined limit.
  • the waiting time is adapted to the prevailing pressure conditions and the container removed when the pressure prevailing in the container p falls below a predetermined limit.
  • One advantage is, for example, that the weight accuracy is increased at a high filling speed, since the removal of the bag does not result in any leakage of filling material caused by increased inner bag pressure.
  • Another advantage is that the filling time is optimized because the waiting time after completing the filling process is not unnecessarily long is selected.
  • the waiting time is adapted to the actual conditions and is therefore never too short and never too long.
  • the processing time is optimized, i. the sum of fill time and settling time.
  • the invention further brings, inter alia, the advantage that a leakage of the container for the material to be filled can be detected early, since an unexpected pressure drop is detectable. Then the further filling process is stopped.
  • the method according to the invention comprises, as further processing steps, removal of the container from the filling device and / or closing by e.g. a welding of the bag opening.
  • air may be added to the material to hold or transport the material. This can be controlled in dependence on the measured pressure p. Furthermore, a setting or control of the speed with which the material is introduced into the container, which preferably takes place as a function of the measured pressure p, is preferred.
  • the present invention avoids or flattenes any pressure spikes that may occur by reducing the filling rate when the pressure exceeds predetermined or selectable limits.
  • a very significant advantage is that due to high pressures caused destruction of bags with subsequent Contamination of the system can be avoided, for example by powdery fillers or their frequency can be largely reduced.
  • the control of the entire filling process is carried out in dependence on the pressure prevailing in the container, so that during the entire filling process, the pressure occurring is kept below the maximum permissible pressure.
  • the filling process can also be specifically controlled so that the maximum pressure is never reached or exceeded, but the pressure is controlled so that it runs as little as possible below the maximum permissible pressure during the entire filling process.
  • in addition to or in combination with a conventional control depending on the filling material and the pressure occurring can be taken into account. A redundancy is advantageous here.
  • the pressure-dependent control allows a faster response to errors in the filling process.
  • the measuring device is connected to a control unit controlling the filling process for exchanging data.
  • the measuring device can be assigned an evaluation unit, which can be connected to the control unit for exchanging data.
