Definitions

  • the present invention relates to a device for filling sacks with flowable or free-flowing, in particular dust-shaped filling material, for example for the fully automatic filling of flat and gusseted sacks made of paper, plastic or a combination of these materials, the sacks being used by means of clamping jaws to hold the lateral sack mouth areas transported to the filler neck and the bags are opened there by suction cups arranged between the jaws while simultaneously moving the jaws towards one another.
  • the ratio between the outside diameter of the sleeve and the inside diameter of the bag is determined by the inflating capacity of the sleeve. If the outer diameter of the sleeve is chosen to be only slightly smaller than the inner diameter of the sack, there is a risk of the sack edge turning over when the sack is automatically pushed onto the filler neck. The bags are therefore pushed on by hand. This would largely avoid the disadvantage of the bag edge turning over. that the outside diameter of the sleeve is chosen to be considerably smaller than the inside diameter of the sack.
  • From DE-OS 15 86 248 and DE-OS 24 18 228 devices are also known in which the sack is pivoted up for placement against the filler neck and the edge of the sack is held in place by expandable clamping jaws. A complete sealing of the edge of the bag is not guaranteed.
  • the object of the present invention is to avoid the disadvantages of the known devices and to provide a simple mechanical, preferably fully automatic device, in which a perfect seal is produced during the filling process, so that even when filling bags with dust, with protection gas-treated or odor-laden material can be safely avoided.
  • this is achieved in a device with devices for holding, transporting and opening the sack by means of expandable flaps which can be lowered into the area of the open sack edge and a telescopically displaceable surrounding the filler neck, arranged on the filler neck and sealed in the extended position, between the spreaders F ormklappen lowerable into the bag edge portion sealing pipe connection is provided at its lower end with an externally arranged Aufblähring.
  • the dimensionally stable molded flaps which are preferably made from optionally surface-treated sheet metal, plastic or the like, make it possible to make the outer dimensions of the sealing connector or the inflation ring arranged on it only slightly smaller than the internal dimensions of the expanded molded flaps or the sack, so that on the one hand the largest possible filling cross-section of the filling or sealing nozzle can be realized and on the other hand a secure seal is guaranteed.
  • sealing segments on the outside in the region of the sack edge, for example a firm and stable outer ring, against which the sack is pressed by the inflation ring after exposure to a pressure medium.
  • sealing segments instead of placing an inflatable cuff on the sealing socket, one could also be provided on the outer ring or both on the sealing socket and on the outer ring.
  • the sealing nozzle 2 which is telescopically displaceable via the actuator or the like 8, is arranged on the filling nozzle 1.
  • the elastic seal 3 is arranged on the lower end of the filler neck in the form of an annular collar, and the stop ring 4 is provided on the upper end of the sealing connector, which could also be designed as an elastic seal or instead of the seal 3.
  • the inflating ring which is arranged on the lower end of the sealing socket and is to be connected to a compressed air source, not shown, is designated by 5.
  • the pivoted flaps 6 are provided, which are actuated via the actuator or the like 7.
  • the sack 15 is held in the still closed state between the supports 14 made of elastic material which are arranged on the inner sides of the transport clamps 12 which preferably extend over most of the sack width and can be actuated by means of the actuators or the like 13.
  • 11 denotes the suction cups for opening the sack 15 and 9, the suction pipe 9 which is guided through the filler neck 1 and which can be lowered and raised by means of the actuator or the like 10.
  • the sack 15 clamped between the transport clamps 12 with a support 14 was here automatically transported to the filling device and in this position was transferred to the side clamps 17 (FIG. 7).
  • the suction devices 11 are placed on the side wall of the bag and, after the transport clamps 12 have been opened, the suction air is switched on via the actuators or the like 13.
  • An actuator or the like, not shown, moves the clamps 17 towards one another, while at the same time the suction cups 11 move away from one another and the bag 15 opens.
  • the form flaps 6 have been pivoted into the sack edge region and spread apart via the actuator 7, as shown in FIG. 2, so that the sack edge region has an opening cross section corresponding to the design of the form flaps.
  • the suction air for the suction cups 11 can be switched off and the sealing neck 2 can now be lowered into the area of the spread-out flaps 6, the stop ring 4 of the sealing neck 2 being pressed onto the elastic sealing ring 3 of the filler neck 1 in the lower end position and thereby filling neck 1 and sealing socket 2 are tightly connected.
  • the molded flaps 6 are then moved upwards in a spread position from the edge of the sack area which is still held by the side clamps 17 and thus prevented from collapsing.
  • the forming flaps emerge from the bag edge portion A is ufblähring 5 supplied with compressed air and thereby the bag 15 completely sealed from the inside.
  • the outer wall of the bag is pressed against the outer segments 16 (FIG. 7) and the bag is thus additionally kept tight from the outside.
  • the bag 15 is then filled with a predetermined quantity of filling material.
  • the suction pipe 9 is inserted via the actuator 10 into the position shown in FIG. 4, ie into the upper edge of the sack.
  • the sealing neck 2 is now raised and moved out of the bag edge area, tightened by moving apart the side clamps 17 of the bag edge area and by moving the transport clamps 12, the bag edge area of these clamped again, the elastic covering 14 of the transport clamps encloses the suction pipe 9 and hermetically seals it from the outside, so that no air can get into the sack from the outside (FIGS. 5 and 6).
  • the part of the suction tube 9 which dips into the edge of the bag is, as shown in FIG. 6, preferably of oval cross-section.
  • a flat, slit-shaped cross section could also be provided, or a larger number of correspondingly small, circular suction openings could be provided in the direction of the sack edge, whereby in any case overstretching of the sack material is avoided and a fold-free return of the sack edge area to an extended position is ensured.
  • the vacuum feed line is closed by means of a valve (not shown) before the suction pipe 9 moves out of the sack edge area and a short compressed air pulse is used to free the suction pipe mouth from any adhering contents sent the intake manifold.
  • the elastic material of the supports 14 seals the edge of the bag immediately behind the end of the suction pipe without creases, so that no air can reach the contents from the outside.
  • the flaps 6 are closed, covering the cross section of the filler neck 1 in a tightly fitting manner and thus preventing that possibly trickling filling material gets into the edge of the sack between the sack walls and thereby impair the subsequent closing of the sack in a subsequent closing station or by a closing device that can be moved up to it.
  • spreading elements such as wedges or the like, which can be inserted into the sack edge area above the transport clamps 12, by means of which this part of the sack edge area is spread apart and makes it possible, for example by blowing out by means of a strong compressed air pulse, to cover this area of approximately to free existing contents.
  • the suction pipe 9 does not necessarily have to be arranged passing through the filler neck 1; rather, this could also be provided in a subsequent position in order to increase the performance of the device.
  • the suction tube 9 can also be surrounded by a protective tube 18 which can be displaced by means of an actuator 19 and which prevents the filling material adhering to the filling material adhering to this, for example, from becoming dirty when the suction tube is pulled out, and the subsequent closing, for example by welding adversely affected.
  • the transport clamps 12 do not necessarily have to be continuous, as can be seen in particular from FIG. 7, but in many cases two clamps arranged only on the side are sufficient, which do not hold the bag in its full width during transport, but only at the ends.
