Definitions

  • the invention relates to a machine for filling and closing of bags and a method for filling of plastic bags with filling material and for closing the filled bags.
  • Such a device is for example from the DE 93 01 355 U known.
  • a device for producing, filling and closing unilaterally open preferably provided with gusseted bags of thermoplastic described in which a first welding and separation station to form the bag with bottom seam, a filling station and a second welding station for closing the bag available.
  • these filling machines are classified in the FFS ( F orm F ill and S eal) category.
  • the filling of dusty goods according to the described known filling method usually leads to a significantly inflated product volume or to a significant reduction in bulk density, since the product accumulates heavily in the free fall with air. This in turn means that significantly more packaging material is needed to fill the product. In addition, the air must be able to escape from the bag again, otherwise it can not be stacked or stored.
  • the US 5,535,792 shows a machine for filling sacks. To bring the sack edges of the open bag tight to the filler neck, which reveals US 5,535,792 Grippers that grasp the corners of the open bag and are movable in the opposite direction. The US 5,535,792 does not disclose a spud and sealant.
  • the EP 0082955 A3 shows a device for filling bags with a side edge of the bags holding clamp.
  • expandable hopper halves are provided which press the bag walls in the region of the gripping means sealingly thereto.
  • the US 2,727,669 shows a weighing and filling device for bags.
  • the US 2,727,669 discloses a sealing ring with which the bag is fixed to the filler neck of the hopper.
  • the EP 1 018 469 A2 shows a filling device for filling sacks.
  • the opening of the filler neck is made of an elastic material and is compressed by means of a pressing device - before the introduction of the nozzle in the bag to be filled. Subsequently, the filler neck expands in the filling opening of the bag and thus seals the filling opening.
  • the EP 1 459 981 A1 suggests, therefore, to introduce the filler neck of a metering of an FFS machine in the opening of a bag.
  • the relative movement between the sack and the filler neck is accomplished by a movement of the sack.
  • the object of the present invention is to propose a machine in which the discharge of filling material proceeds with less dust.
  • the clamping means will comprise grippers or suckers which grasp or suck in parts of the bag material and pull them outwards, that is, away from the main axis of symmetry of the bag. In this way, the bag material is stretched and nestles in a better way to the connection piece and / or the metering tube. Therefore, the clamping means comprise, in addition to any gripping means actuators, so devices apply the force that pull the gripping means and the bag material in the manner described. Often, linear actuators or working pistons will be used for this purpose.
  • the surfaces in opposition are matched in shape to one another so that they interlock when the sealing elements are employed. This is easy if the elements are just pronounced on the surfaces where they touch the bag material.
  • the spigot should have at least two passages for elements that pass through it.
  • one or more vent tubes engage through the metering in the bag.
  • the venting of the bag during the filling process is of great advantage, since air, which can not escape at first, means overpressure. Such an overpressure may discharge to the outside during filling and may lead to dusty contents again.
  • the or the vent tubes can then be followed by filters that prevent leakage of Gugutstaub.
  • the vent pipes can be made of sintered material.
  • the connecting piece has at least one corner.
  • the tension member then pulls the bag material into a shape that spans the corner. If then - which is usually advantageous - the employment of the sealing elements takes place against the already tensioned or prestressed film, the film nestles very well on the sealing element.
  • the direction of action of the clamping element is the direction in which the sack material is actually pulled during the clamping movement. This direction can also be influenced by other additional machine elements such as the density elements - that is, deflected.
  • each one corner of the filler neck - which may have more corners - are assigned.
  • the metering is usually perform a further relative movement relative to the connecting piece to advance into the interior of the bag and here to fill the bag with filling. If a suitable pre-positioning between the bag and dosing, the two aforementioned relative movements can also coincide. In general, however, any possible sequence of these relative movements between the sack, the dosing member and the connecting piece is advantageous or encompassed by the present invention.
  • both types of gripping means will be adapted to grip the sack at its upper edges, not blocking the central area of the sack opening, since this central area is reserved for sack filling.
  • the gripping means are gripper pair.
  • opening means for the sack opening is advantageous. Often these are also assigned directly to the filling station. They often include suckers or other grippers. You should open the bag before the nozzle is inserted into the bag by a relative movement. Advantageously, then carried out the tensioning of the bag. It is also advantageous if the bag material is pressed with sealing means against the connecting piece. This is best done after tensioning the bag material.
  • a tubular film web 15 (see FIG. 1 ), preferably with inserted gussets, is first conveyed by a preferred roller system 9 in a horizontally movable transport, such as a pair of grippers 18.
  • the bottom welding takes place 13.
  • the filling station 60 takes over a further transport 4, which consists of 3,4,5, the bag section.
  • the empty bag is now opened with a suction system 16.
  • the gripper 4 is moved in the Z direction or in the -Z direction (inwardly).
  • the connecting piece of the transport system 3 is moved into the bag and protects the sack inner surfaces from contamination by possible product adherence to the metering tube 2,21.
  • the opened bag is pulled by the transport system 3, 4, 5 on the metering tube 2,21 until the lower end of the bag is approximately equal to the Gregutaustrittsö réelle 31.
  • the bag bottom support device 32,33,34 is in the embodiment shown below the bag floor hazards. However, a bag bottom support device 32, 33, 34 is not absolutely necessary. Rather, the relative movement of the bag relative to the Be Stirllorgan 2,21 mainly caused by the fact that the frame 5 along the guide 6 moves. This is represented by the double arrow 35. In this embodiment of the invention, therefore, the bag is moved relative to the Be refhapllorgan 2,21.
  • the closure tube 21 is lifted and releases the product outlet opening 31.
  • the product / bulk material 24 is filled in the bag. Meanwhile, the transport system 3,4,5 lowers the bag in such a way that the product outlet opening 31 is always below the filling level. However, even before the end of the metering of the product / bulk material 24, the product outlet opening 31 may be located at least once above the filling level 38.
  • the closure tube 21 is lowered and closes the product outlet opening 31 by making contact with the closure 20.
  • the connecting piece is pulled out of the bag.
  • the gripper (s) 4 of the transport system 3, 4, 5 is now moved counter to the Z direction (out of the bag) and tightens the opening area at the upper edge 25 of the previously opened bag.
  • Another transport means 10 takes over the filled bag 8.
  • the closing device 14 By means of the closing device 14, the upper edge of the bag 25 is now closed. If necessary, it can be sucked out by the filter integrated in the closure tube 21 together with the dosing process. The required vacuum is introduced via the pipe 23.
  • the integration of the filter in the closure tube allows a very compact design, which makes it possible to fill even relatively small bags. The suction of the air leads to a certain extent a compression of the bulk material. As a result, a sack size appropriate to the product quantity can be selected.
  • vibration generators or beaters 29 This effect of product compaction can be further enhanced by the additional use of vibration generators or beaters 29. It is advantageous here to set the dosing tube 2, 21 in vibration by means of a vibration generator 29, since it is located within the product at least with parts of its lateral surface during filling. The vibrations are transmitted from the dosing 2.21 to the filling material 24, in which then takes place a compression. Another advantage of the "vibrating metering tube" 2.21 is that the formation of product adherence to the metering 2.21 is thereby largely avoided.
  • the vibrator 29 could also be arranged on the "bag bottom support device" 34.
  • a particularly advantageous embodiment of the carriage is to store the frame 5 together with the neck 3 and the transport 4 on sensors.
  • the sensors send their signal to a weighing electronics, which ultimately controls the dosing process.
  • the absorption 16 may also be mounted on the sensors, but should advantageously be stored elsewhere, since the suction 16 is usually no longer in contact with it during the filling of the bag 11.
  • the metering or pipe 2 In the metering or pipe 2 is a screw 7, can be promoted with the filling material 24 from the hopper 1 without much dust in the bag 8.
  • the various sensors 26 (in particular weighing sensors or load cells) indicate advantageous locations for attaching such sensors.
  • the conveyor belt 27 transports the filled bags (8). In the vicinity thereof, the checkweigher 30 and the vibration generator 29 are mounted.
  • FIGS. 3 to 8 show a plan view of the essential for the sack opening and bag filling elements of the filling station in a device for Forming, filling and closing sacks. This supervision is in FIG. 2 represented by the view III - III.
  • FIG. 3 shows a still unopened empty bag 11, which comprises two outer walls 102, 103.
  • a sack with gussets 104, 105 can be seen.
  • the empty bag 11 is in the region of its gussets 104, 105 of grippers 106 and 107 of the feed device 18, not shown here (see FIG. 1 ).
  • the grippers 106, 107 which are rotatably mounted in the holders 108, 109 in a manner not shown, hold the bag during the entire filling process.
  • the holders 108, 109 are based on the frame 5, which is likewise not shown here in detail, and are displaceable relative to this frame 5 in a manner described below.
  • FIG. 4 shows the same elements as the FIG. 3 However, opening means, which are formed in the present embodiment as a sucker 110, 111, employed from the outside to the bag walls 102, 103 and suck them.
  • opening means which are formed in the present embodiment as a sucker 110, 111, employed from the outside to the bag walls 102, 103 and suck them.
  • the FIG. 5 represents the opening process of the empty bag 11.
  • the sucker 110 in the direction Y and the sucker 111 in the direction -Y is moved.
  • the holders 108 and 109 are moved in directions Z and -Z, respectively, to compensate for the reduction of the lateral extent of the bag 11. In this way, a filling opening at the upper end of the bag 11 is formed. This situation is already in connection with the FIG. 2 been described.
  • FIG. 6 shows a similar situation as the FIG. 5 , Only a sealing element 112 was inserted into the interior of the bag 11.
  • the sealing member 112 is already above in connection with the FIGS. 1 and 2 and has been referred to in the introductory description as a connecting piece. In the context of this application, the words “sealing element” and “connecting piece” thus refer to the same element.
  • the contour of the sealing element 112 in the plan view is similar in this embodiment, the cross section of a Convex lens.
  • the sealing element 112 only needs to be introduced into the interior of the bag 11 approximately so far that the surface of the sealing element lies on a plane or slightly below the upper edges of the walls 102 and 103 (see FIG FIG. 9 ).
  • the sealing element 112 After the introduction of the sealing element 112, the negative pressure, which is applied to the outer walls 102 and 103 via the suction cups 110 and 111, can be removed and the suction cups 110, 111 can be removed.
  • the sealing element 112 has at least two passage openings. In the present embodiment, three such openings can be seen. The largest opening represents the filling opening 113, which is preferably arranged centrally. Through this filling opening, the product can be filled into the interior of the bag 11. In a first embodiment, however, the sack is moved relative to a fixed in the device filling tube. In a second embodiment, the sack can be held immovable while the filling tube is moved into the interior of the sack 11 through the filling opening. A combination of both embodiments is, as described, conceivable.
  • the sealing member 112 surrounds the filling tube and closes the space between the filling tube and the walls 102 and 103.
  • the bag walls 102 and 103 are therefore not immediately adjacent to the filler neck.
  • the bag 11 is raised so far that the distance between the bottom of the bag 39 and the lower outlet end 31 of the filling tube 2 is very small.
  • the bag 11 is lowered continuously, so that the distance between the lower outlet end 31 of the filling tube 2 and the level of the contents 38 remains very small. The distance can assume a negative value. This means that the outlet end 31, as already described above, below the Gregutpegels 38 is located. In this way, a dust development during the filling process is avoided. It should be noted at this point that the filling takes place only after the in the FIG. 8 shown step has been performed.
  • the sealing element 112 further comprises two passages 114 through which, for example, suction nozzles are introduced into the interior of the bag 11 can be. With such suction can register the registered during the filling process air and compress the product in this way.
  • FIG. 7 now shows that the holders 108 are again moved outwards, in the directions -Z and Z.
  • the walls 102 and 103 lie partially outside from the outside to the edge of the sealing element 112. However, the space between the walls 102 and 103 and the sealing element 112 is not completely closed.
  • clamping elements 115 are made from the outside to the sealing element 112, so that the walls 102 and 103 are held by clamping between the sealing element 112 and clamping elements 115 or between two clamping elements 115. In the region of the sealing element 112, therefore, a single wall of the bag is respectively clamped between this and a clamping element. Between two clamping elements 115, however, both walls 102 and 103 are clamped lying on each other. Again FIG. 8 can be seen, the clamping elements 115 on two areas. A first area presses against the sealing element 112, so that a bag wall 102 or 103 is clamped.
  • a clamping element 115 presses against a second clamping element, which clamp the bag walls 102 and 103 between them. Since the bag walls are biased by the holder 108, results in an extremely high tightness of the bag interior with respect to the bag exterior. This applies even to the region 116 of the bag, in which neither a clamping element 115, nor the sealing element 112, nor the holder 108 attack. Due to the fact that not all areas of the bag wall must attack a device element in order to produce sufficient tightness, the format of the bags, in particular their width, can also be varied.
  • the contour of the clamping elements is adapted to the contour of the sealing element, so that no free space remains.
  • the holder 108 are thereby acted upon with an outward force, which is less than the force with which the walls 102 and 103 according to the FIG. 7 be applied to the sealing element 112.
  • This situation is in the FIG. 8 by compared to FIG. 7 shorter arrows Z and -Z symbolizes.
  • the holders 108 are moved by means of actuators, which may be arranged on the frame 5.
  • actuators may be, for example, linear motors.
  • pneumatic pistons are conceivable for this purpose.
  • the actuators are in the FIG.
  • the material of the bag 11 can be pressed against the sealing element 112 by the clamping elements 115, without being damaged by the holders 108 due to excessive tension. However, the force with which the holders 108 are acted upon is nevertheless so great that the regions 116 of the walls 102 and 103 abut one another without the clamping elements 115 exerting a force here. Even in such areas 116, the interior of the bag 11 is sufficiently sealed against the environment.
  • FIG. 9 shows the view IX - IX FIG. 7 , In this FIG. 9 In solid line, the sealing element 112 can be seen before it is introduced into the bag. After being displaced in the direction of the arrow X, the sealing element 112 is located inside the bag 11 just below the upper edge 117 of the bag 11. In this position, the sealing element 112 is shown with broken lines.
  • the target areas 118 can be seen, in which the grippers 106 and 107 engage.
  • the front grippers 106 and 107 can be seen, which engage the wall 103.
  • the rear grippers 106 and 107 grip the wall 102.
  • the target areas are far outward. For example, in a gusseted bag these outboard areas are the gusset areas.
  • the target area 118 is also arranged as close as possible to the sack top 25.
  • the bag 11 can only be filled to a region that lies well below the target area 118 in which the grippers 106 and 107 engage, any bag material that projects upwards beyond the grippers 106 and 107 is useless and should be saved become.
  • the target areas 118 are arranged in the right and left upper corner of the bag 11.
