Definitions

  • the invention relates to a method for filling sacks with a filling material, in which the filling material is filled into a feed trough which is arranged on a mobile platform.
  • plastic or jute sacks are filled with sand or another suitable bulk material. This filling is generally carried out in such a way that the sack to be filled is stopped by one person while the filling material is shoveled in by a second person. Such a procedure is time-consuming and personnel-intensive. Furthermore, shoveling the sand into the mostly small and narrow sacks poses an increased risk of injury to the person holding the sack at its opening.
  • the sandbags be filled by a single person using a special device, in order to shorten the filling process and considerably reduce the risk of injury, and to fill in the sand as far as possible without loss of material .
  • the empty sandbag is drawn onto a filling funnel in the vertical direction, the upper edge of the sack being tensioned or held with one hand on the filling funnel.
  • the lower part of the sack rests in a support cup to absorb the weight that occurs during filling.
  • the sack is filled by gravity, and the bulk material is dosed manually using a manually operated flat rotary valve.
  • this solution has a number of disadvantages.
  • the device must first be constructed in a complex manner before it can be used.
  • the sack on the downpipe can be filled by just one person, but permanent refilling of the feed hopper is required, with the height difference also having a negative impact here.
  • WO 01/36271 A shows a mobile bag filling system that can be operated largely automatically. After filling, however, the sacks must be closed in a separate operation, which means a corresponding effort. Further bag filling systems are described in DE 202 06 430 U and in US 5,437,318 A. However, bag filling systems of this type are not suitable for reliably and quickly filling a large number of bags in the event of a disaster on site under difficult conditions.
  • the object of the present invention is to provide a method with which it is possible to ensure an efficient filling process even under difficult conditions.
  • the filling process should be able to begin immediately and without extensive preparation work.
  • Another object of the invention is to provide an apparatus with which such a method can be carried out effectively.
  • the method according to the invention is characterized in that the sacks designed as valve sacks are unwound and separated from a sack roll mounted on the mobile platform and are successively filled with the filling material by gravity.
  • Safe operation can be ensured in that the filling material is conveyed from the feed trough, preferably into a feed chamber, by a screw conveyor.
  • a mechanically particularly favorable solution provides that the discharge of the conveyed material from the feed trough is regulated by a rocker arranged on the bottom.
  • a particularly advantageous variant of the method according to the invention is characterized in that the filling material is metered from a storage container, the filling material being brought from the storage trough via a screw conveyor designed as a distributor spiral into a metering storage chamber, the filling volume of which is infinitely variable, and then via a two-part filler neck is filled into the sacks, a movable tube engaging in the opening of the sack. This ensures that the bags are evenly filled.
  • the Sack tape as a sack roll is unrolled over the rolls and the pair of rolls so that the sack band is tensioned when a movable pipe is threaded into an opening of the sack band by means of a preferably pneumatic lowering device, so that the filling material is then filled into the sack by gravity, that Movable pipe pulls a short distance out of the filling opening of the sack and the filled sack is then separated from the sack belt, closed and transported out of the sack filling system via a conveyor.
  • a secure closure of the sacks is achieved if, after filling a sack designed as a valve sack, the movable tube withdraws a short distance from the filling opening of the sack and compressed air is then blown into the sack immediately via openings, whereby the valve sack closes automatically.
  • the present invention relates to a device for filling sacks with a filling material, with a mobile platform on which a feed trough is arranged, which is intended for receiving the filling material.
  • this device is characterized in that a bag roll is mounted on the mobile platform and that means are provided to unwind and separate the bags from the bag roll and to fill them with the contents by gravity.
  • a vehicle trailer can serve as a mobile platform, but also a self-propelled machine or, on the other hand, a container that can be brought to the place of use with the appropriate means of transport.
  • a mechanically simple and robust solution provides that the feed trough has a half-shell as a base element, in which there is an outlet opening, and in particular that a screw conveyor is located within the half-shell. As a result, the discharge medium can be reliably discharged from the supply trough.
  • the screw conveyor has a right-hand part and a left-hand part, which are preferably connected to one another via the outlet opening.
  • Blockages can be avoided in that there is a support preferably made of plastic or ceramic in the half-shell or that a wear protection layer is applied to the half-shell.
  • outlet opening can be closed by a rocker.
  • the material transport is particularly secured by the swing arm on their edges facing outward brushes for securely sealing the gap between the rocker and the inside of the half-shell in the region of the outlet opening.
  • a supply chamber which can be closed by a closure device, which is preferably designed as a slide, and that there is a filler neck opening below the closure device, which preferably consists of two tubes, and if a lower one Tube is preferably extendable pneumatically. The insertion of the tube into the sacks is facilitated in that the lower tube has a specially shaped trunk at its free end.
  • a holder for receiving a bag roll is provided, the rolls and a pair of rolls for guiding the bags forming a bag band are arranged downstream, a separation device being able to connect to the pair of rolls for further automation. It is particularly favorable if the pair of rollers is mounted so as to be resiliently movable about the axis of one of the rollers.
  • An alternative embodiment variant of the invention provides that a metering screw is provided in order to discharge filling material from the supply trough via an always open outlet opening.
  • a particularly precise metering of the filling material can be achieved in that it consists of an upper filling funnel and a lower filling funnel, as well as a flexible sleeve which surrounds the two filling funnels on the outside, and that one of the filling funnels is preferably held by a frame device. It is particularly advantageous if the upper hopper and the lower hopper are designed to be displaceable relative to one another in order to change the volume of the feed chamber.
  • the risk of blockages can be minimized in that the hopper is held by a linkage that has a vibrating device.
  • Automation can be particularly facilitated by providing sensors for determining the position of markers.
  • the present invention relates to a valve bag, made from a film or semi-tubular web with a valve tube piece which is tapered conically to the inside of the bag.

  • Such bags can be made of paper or plastic.
  • DE 28 20 956 describes a valve bag which is made from a plastic tube sheet and which has a piece of valve tube welded into the side wall. For the purpose of filling, this valve bag is pushed horizontally onto a filler neck of a filling device. So that the valve bag lies tightly against the filler neck, the valve hose piece is tapered towards the inside of the bag and has a diameter corresponding to the filler neck diameter at its inner opening in the expanded state.
  • valve side wall lies against the inner wall of the bag.
  • This application of the valve side wall to the inner wall of the bag is fixed by a certain contact pressure on the part of the filling material. The sack is thus protected against the contents from escaping.
  • valve bag is pushed onto the hopper.
  • preset tolerances of a plug-on device can be exceeded, as a result of which the valve bag is not fitted properly.
  • the result is that the valve bag slips during the filling process. This flow makes it necessary to interrupt the filling process.
  • Another object of the present invention is therefore to provide a valve bag which is filled purely by means of gravity and the use of which avoids the disadvantages mentioned.
  • valve bag is created, the bag valve of which is not arranged in a side wall as is conventional, but is located in the upper narrow side of the bag.
  • the bag valve forms the entire upper narrow side.
  • the sack according to the invention can consist both of plastic and of paper or of paper coated on the inside. In principle, its application is not limited to mobile bag filling systems and also not for use as flood protection.
  • the bag filling system according to the invention is characterized by its mobility and its fully automatic filling of specially developed bags supplied in rolls of, for example, 2,500 pieces, which are preferably used for the construction of walls and dams, for example in civil and military use, such as in disaster relief can come.
  • the system can be manufactured as a trailer body as well as a self-propelled body with or without its own energy supply.
