Definitions

  • the invention relates to a method for expelling separated in a film packaging system of film bags supernatants, in which the supernatants are separated in a separation welding device and discharged perpendicular to a transport plane T for the film bag down.
  • the invention further relates to a corresponding expulsion device for separated in a film packaging system of foil bags supernatants.
  • the foil bags enclose the packaged goods to be packed.
  • the expulsion devices mentioned here are used in particular for projections which, seen in the transport direction, have been separated from the film bags at the front or rear of the items to be packaged by means of cross-cut welding devices. In principle, however, their application is also possible in connection with projections which are laterally separated from the film bags with respect to the transport direction of the items to be packaged, the corresponding separating welding devices then being in the form of a longitudinal separation welding device.
  • the Trennabsch spaung takes place in both embodiments in standing Packgut Glaen means of upper and lower Trennsch dobalken, which are brought near the transport plane T for the film bag in contact.
  • the transport direction of an already sealed Packgut thoroughlyes is changed by 90 ° and separated the already closed film packaging with another transverse to the new transport direction separating welding immediately before or behind the Packgut cafe in a final separation process.
  • the separated supernatants are led out laterally out of the system transversely to the feed direction of the packaged product in the transport plane.
  • the invention has for its object to provide a method and an apparatus with which separated supernatants of foil bags, carried away in a space-economical manner from the plant, ie can be expelled. This should also be especially smaller, so after separation very narrow supernatants safely detected and removed.
  • the solution consists in a method for expelling separated in a film packaging system of film bags supernatants, in which the supernatants are separated in a separation welding device and discharged perpendicular to a transport plane for the foil bag down, the drive for expelling the supernatants down below the transport plane by means of at least one horizontally oriented drive roller, which is displaceable or pivotable between an insertion position for the projections and a Austreibposition for the supernatants.
  • the actively driving roller is designed to be movable in order to bring the line of detecting the projections closer to the transport plane.
  • the supernatants are introduced after fixing the film bag by the separating welding device in a feed slot below the transport plane between the drive roller in the insertion position and a counter-holder. This considerably simplifies the process without sacrificing operational safety.
  • the drive roller presses the supernatants each in the Austreibposition against the counter-holder, which is supported in particular resiliently. Furthermore, it is provided that the supernatants are discharged after the complete separation from the foil bag by the separating welding between then only driven drive roller and counter-holder bar down.
  • the drive roller is preferably displaceable or pivotable against a resilient counter-holder strip.
  • This counter-holder strip is preferably provided with a plastic coating and supported in a particularly favorable manner directly on the lower punch of the separating welding device.
  • the springs, with which the counter-holder strip is supported on the lower welding punch, can be integrated into this lower punch. Preference is given to a plurality of evenly distributed over the length of the lower punch compression springs, so that bending phenomena are avoided on the counter-holder strip.
  • the surface of the drive roller is knurled in a favorable configuration and / or formed with a plurality of circumferentially extending punctures. This ensures that the separated film parts do not wrap around the drive roller. At the same time, this ensures a safe transport of the separated film parts, whereby air pockets and wrinkles can be pushed away without the removal of the supernatant is impaired.
  • the drive roller is conveniently pivotable in pairs parallel pivot levers, especially in two-armed pivoting levers.
  • a driven gear can be rotatably connected directly to the drive roller, while a driving gear is arranged coaxially on a pivot axis of the pivot arms. This facilitates the entire configuration of the drive means.
  • the driving and the driven of said gears can be coupled together via a spur gear set or a chain or a toothed belt.
  • the drive means for the Niederdrückerance in particular an actuating cylinder used for this purpose, are preferably arranged on a cross-beam of the separation welding device, so that by lowering this cross-beam initially the film bag can be fixed in the supernatant of the Trennsch dipvorraum and only then by driving the actuating cylinder for the Niederdschreiberelf the supernatant is introduced into the feed slot, so that no distortion or displacement of the foil bag can result. Rather, the supernatant is threaded with uniform width in the intake slot. Thereafter, the drive roller is pivoted so that the intake slot is closed and the supernatant between the drive roller and the counter holder bar is fixed. After completion of complete supernatant suppression, the drive roller is set in motion. At the same time, due to the coupling with the drive of the transport roller conveyor, the package item is guided away from the separating welding apparatus in the reduced foil bag.
