Definitions

  • the present invention relates to a treatment device and a method for treating an open bag, in particular filled with a bulk material, wherein the bag is filled in particular with a pulverulent or powdery dusty product and is closed at a closing station.
  • Open sacks are often made of plastic film that protects the bag contents from moisture.
  • building materials such as cement are increasingly being filled into open sacks made of plastic film. These offer the considerable advantage that they do not usually have to be protected from rain on the construction site.
  • air channels are provided in the bag wall, through which part of the still contained air escapes at the applied pressing pressure. But through these channels not only air can escape from the interior of the bag to the outside, but in unfavorable cases it can also happen that moisture from the outside enters the bag, which can spoil the product. In addition, product can also escape.
  • a method for filling open sacks with powdery material has become known, after which the sack is first shaped and a first, lower end is closed. After filling and before closing the bag, a suction device is inserted at the top of a side end of the bag into the interior of the bag and there is sucked out excess air from the bag. In addition, a traveling cleaning device along the The top opening of the bag is reciprocated from one side to the other side to clean the inner top edge of the bag with an air jet during reciprocation with the cleaning device, thereby removing particles.
  • a disadvantage of this known state of the art is the considerable expense with the suction device dipping into the bag and the additional cleaning device. Both the suction device and the cleaning device must be moved to the bag in each case. In addition, the cleaning device still has to be automatically moved back and forth along the upper edge.
  • the object of the present invention to provide a treatment device and a closure station, as well as a method for treating a filled open bag, thus enabling effective venting and reliable closing of a filled open bag.
