Definitions

  • the present invention relates to a device for filling bulk goods into sacks and in particular for filling powdery foods into open-mouth sacks.
  • a device for filling bulk goods into sacks and in particular for filling powdery foods into open-mouth sacks.
  • Such a device can be designed as an FFS system (Form-Fill-Seal) and can include a bag production in order to produce the bags to be filled directly on the device from, for example, a tubular film.
  • FFS system Form-Fill-Seal
  • the invention is used in the filling of powdery foodstuffs or foodstuffs or other powdery products in which high hygienic standards must be observed.
  • Baby food or its ingredients such as in particular milk powder, dextrose, starch, etc., are preferably filled into open-mouth bags.
  • high and highest hygienic standards must be adhered to.
  • EHEDG European Hygienic Engineering and Design Group
  • the "European Hygienic Engineering and Design Group” is an amalgamation of various institutes, companies and facilities that discuss and publish guidelines for the production and packaging of food.
  • the lines on the machine should be easily accessible and individually attached next to one another to enable easy cleaning of the entire system.
  • This allows high hygienic Standards are adhered to, as any contamination on the system is easily accessible and therefore easy to remove. Nevertheless, the cleaning effort is relatively high.
  • Another disadvantage is that the built-in components have to meet the high hygienic standards, which increases manufacturing costs.
  • the cables and lines should be arranged openly next to one another in cable trays. This creates very wide cable and hose routes that make access to the machine more difficult.
  • DE2529859 A1 describes a crane with a cabin, wherein extracted cabin air can be used to supply various electrical components, such as switching devices, with pressure, which are located in the vicinity of the cabin. The overpressure prevents dirt from penetrating the components and the occurrence of functional errors is thus reduced.
  • a device according to the invention is used to fill bulk goods into sacks and, in particular, to fill powdery foods or the like in open sacks.
  • the device according to the invention comprises a support structure and at least one filler neck received on the support structure, to which a sack is hung for filling and held on the filler neck by means of at least one bag holder.
  • the support structure comprises at least one hollow profile with a control component at least partially accommodated therein and protected there from contamination.
  • An air outlet of a pneumatic component is provided for the hollow profile in order to place the hollow profile under a higher air pressure than the surroundings during operation.
  • at least one sensor device is arranged as a control component in the hollow profile.
  • a pressure sensor is arranged there, which detects a measure of the pressure prevailing in the hollow profile.
  • the support structure to which the sack is attached and held during filling comprises at least one hollow profile.
  • a control component is received on the hollow profile in such a way that it is protected from contamination. It is also possible for several control components to be received in a protected manner on and in particular in the hollow profile. Because the hollow profile surrounds the control component or the control components, no dirt particles can accumulate there on the control component. This makes cleaning considerably easier, since the control component itself does not have to be cleaned. It is sufficient to clean the hollow profile, which is particularly smooth-walled, from the outside.
  • connecting lines for air supply or electrical connecting lines or the like individually next to one another in order to enable them to be easily cleaned, rather a plurality of lines can be routed as a cable harness or the like within the hollow profile.
  • Each individual line can be viewed as a control component.
  • An air outlet in the interior of the hollow profile can be used to specifically generate overpressure in the hollow profile, so that the penetration of particles or dirt into the interior of the hollow profile can be largely avoided. This means that it is not necessary to clean the inside of the hollow profile.
  • the hollow profile or at least one hollow profile is sealed to the outside.
  • the hollow profile is used in the following, a plurality of hollow profiles can also be provided and meant, each of which comprises one or more control components inside.
  • the device is used to fill sacks of bulk goods.
  • the device for filling is particularly preferred powdery bulk goods and in particular food used in open-mouth sacks.
  • the open sacks are preferably at least partially made of film.
  • the sacks are made from a tubular film.
  • the sacks (the term sack is always understood to mean an open sack in the context of the present invention) are preferably two-ply and peelable, so that after the removal of an outer layer and possibly still containing dirt particles, the inner layer protects the inside of the filled sack free of dirt. This allows the outer layer to be removed after transport and before further processing.
  • the device according to the invention can also be suitable for filling valve bags.
  • the hollow profile is sealed off from the outside.
  • At least one, in particular pneumatic, control valve is preferably arranged as a control component in the hollow profile. It is also possible for 2 or 3 or more differently activated control valves to be arranged as control components in the hollow profile.
  • the hollow profile can, for example, comprise at least one valve island with several (pneumatic) control valves as control components. Because control valves are arranged in a protected manner inside the hollow profile, commercially available control valves can be used as control components. These control valves do not have to meet the increased hygienic standards that would have to be applied outside the hollow profile. This also reduces the (financial) outlay for producing a device according to the invention.
  • At least one control device is arranged or accommodated in the hollow profile.
  • at least one sensor device is arranged as a control component in the hollow profile.
  • one or more can also be in the hollow profile Be accommodated connecting cables.
  • Such a connection line can be designed electrically, pneumatically or hydraulically. It is also possible that electrical and pneumatic connection lines are housed inside the hollow profile.
  • At least one sensor line is arranged in the hollow profile.

  • the sensor line can be connected, for example, to a bag sensor, a pressure sensor, a position sensor, a position sensor or a filling level sensor.
  • At least one sensor is arranged within the hollow profile.
  • a pressure sensor is arranged there, which detects a measure for the pressure prevailing in the hollow profile. Then, controlled by the pressure sensor, air, for example, can be passed into the interior of the hollow profile so that the pressure level does not drop below a predetermined pressure level there. By maintaining a certain overpressure, the penetration of dust or dirt particles into the interior of the hollow profile can be prevented very reliably.
  • the bag holder is attached to the hollow profile or to at least one hollow profile.
  • several bag holders are attached to the hollow profile.
  • the connection and / or control lines of the sack holder can simply be fed through the interior of the profile, so that the number of surfaces that are susceptible to contamination decreases outside of the hollow profile. This reduces the cleaning effort.
  • the bag holder or at least one bag holder can be controlled via (at least) one pneumatic cylinder and / or electrically.

  • the exhaust air line of the pneumatic cylinder or at least one pneumatic cylinder opens into the interior of a hollow profile or of the hollow profile. It is also possible for the exhaust air line to have at least one outlet in at least one hollow profile.
  • Such a configuration offers considerable advantages, since the discharge of the air from the pneumatic cylinder into the interior of the hollow profile already ensures a certain air supply there, so that the required overpressure can possibly be provided by the exhaust air of the pneumatic cylinder alone.
