Definitions

  • the invention relates to a method for filling and closing a plastic sack, in particular a gusseted sack, with a dust-like or granular filling material, in which the opening edge of the flat sack, which is clamped in the side areas, is opened in a parallelogram shape, the parallelogram-shaped sack opening being given an essentially round shape, a ring zone of the inner surface of the sack adjacent to the opening edge is blocked off from the inside of the sack, the sack is filled with the filling material when the ring zone is blocked off, the filled sack is sealed between the ring zone and the filling surface and the sack is welded closed in the area of the ring zone.
  • the invention further relates to a device for performing this method, consisting of a filling station with a sack holder with two pairs of jaws and two suction cups, a pair of round spreading flaps, a filling member that can be lowered under the sack holder, a tubular body that surrounds the filling member and can be lowered independently of it, and an over the bag width-reaching pair of clamps and a welding station for the top seam.
  • an axially displaceable, rigid sleeve with an external blowing ring is provided on the filler neck for sealing the filler neck against the bag.
  • the blah ring only connects the cuff to the upper edge of the sack, so that the sack is sealed against the cuff, but no ring area of the inside of the sack that is sufficiently wide for a weld seam is kept free of dust.
  • the invention has for its object to provide a method and an apparatus for filling a plastic bag with subsequent head seam welding so that the dust-containing air displaced from the bag can not escape into the atmosphere.
  • a method and an associated device for carrying out the method are to be created in which the purity of the inner surface of the sack in the area of the head weld seam to be applied is achieved without using the previously only partially effective measures of blowing off, brushing off and neutralizing the electrostatically adhering dust.
  • This object is achieved according to the invention in the method mentioned at the outset by blocking the round ring zone from the bag interior in that an essentially cylindrical one
  • the tubular body made of flexible material is retracted into the ring zone and the sack in this ring zone is stretched out around the cylindrical tubular body by pulling the sack wall material outwards.
  • the closed ring zone is brought out of its round shape into a flat shape and the ring zone is only closed afterwards the sealing of the filled sack.
  • the ring zone can no longer be contaminated by dust deposits after its barrier has been released.
  • the top seam welding in the area of the ring zone is therefore no longer impaired by dust particles adhering to the inside of the sack wall.
  • the round ring zone is blocked off by driving an essentially cylindrical tubular body made of resilient material into the ring zone and stretching the sack in the ring zone by pulling sack material around the tubular body.
  • the cylindrical tubular body retracted into the ring zone is stabilized against deformation on the inside by tensioning the sack. This ensures that when clamping the tubular body is not deformed by the bag tension. Such a deformation would lead to contact between the filler neck and the pipe body when the filler neck was retracted and thus impair the weighing.
  • the filled sack is gripped in the two gusset areas and tightened between these areas. If the closed ring zone is brought into a flat shape after the bag has been filled, rounded areas remain towards the side folds because of the deformable tubular body stuck in the ring zone. The result of these rounded sack areas is that folds are also caught by these clamping jaws when sealing by means of two clamping jaws. As a result of these folds, small air channels can remain after the seal, through which dust-laden air can reach the ring zone, and the formation of the head seam is impaired.
  • the tightening according to the invention eliminates the wrinkles initially gathered during the sealing, so that complete tightness is ensured.
  • the sack material is preferably pulled diametrically outwards in the two gusset regions and the sack wall is thus placed tightly against the outside of the tubular body in the ring zone. Since the sack is already clamped in the side fold areas from its opening, it is advantageous to combine the clamping of the side fold areas with the diametrical pulling off of the bag material.
  • the closed ring zone of the sack is squeezed from the round to a flat shape which is thicker at the two ends adjacent to the sides or gussets than in the middle. Since the tubular body stuck in the ring zone of the sack is brought into the same flat shape, this shape results in a reduced material stress on the tubular body strongest bend in both places.
  • the blocking of the ring zone is expediently released by releasing the pinch of the sack and tubular body and then withdrawing the tubular body from the sack.
  • the tubular body then automatically returns to its cylindrical shape so that it can be retracted during the next filling process.
  • the air displaced by the filling material during the filling is expediently drawn out of the bag between the filling material flow and the tubular body which has been moved into the ring zone. Since the filling material flows downward within a filling pipe, channels for the extraction of the displaced air can be provided between the filling pipe and the tubular body.
  • the inward side folds are placed against the bag wall when the bag opening is shaped round.
  • the gussets are so deep that they still protrude inwards after the sack has been opened in parallelogram form.
  • the inward side gussets are placed flat against the sack wall.
  • the above-mentioned device for performing the method according to the invention is characterized in that the tubular body made of an elastically deformable material can be lowered into the sack a bit below the round-spread opening edge, each jaw of the sack holder carries a movable clamping body and each clamping body has a displacement - And / or rotary drive is connected, through which the sack clamped between the clamping bodies can be pulled off the tubular body.
  • annular zone of the sack lies sealingly against the tubular body and thus blocks this annular zone from the sack interior filling with filling material, so that this zone is kept free of dust deposits.
  • a dimensionally stable support ring can be moved vertically between a raised position and a position lowered into the tubular body up to approximately on its lower edge. Due to the support ring that can be lowered into the tubular body, the tubular body is dimensionally stabilized in the region of the ring zone, so that it cannot deform when the sack wall material is pulled off and tensioned, which would interfere with the retracting of the filler neck through the tubular body.
  • the jaws of the pair of jaws each have two cheek parts arranged one behind the other in their longitudinal direction with rubber-coated engagement surfaces, and the cheek parts are attached so that they can be moved apart and moved together in the longitudinal direction.
  • the sack which is initially more or less wrinkled between the product surface and the flat-clamped ring zone, can be smoothed out without wrinkles, so that the subsequent head seam welding cannot be impaired by folding.
  • the clamping bodies expediently consist of an elastically deformable material, in particular rubber. Due to the deformability of the clamping bodies, it is possible to re-engage them with the sack during the removal of the sack material, i.e. "follow up".
  • the two clamping bodies of a pair of jaws are connected to a common displacement drive, preferably connected to a pneumatic piston / cylinder unit. Since the two clamping bodies can be pivoted according to the clamping jaws, the connection to the common displacement drive takes place via a linkage which does not hinder the pivoting of the clamping jaws or is designed such that the connection to the drive unit is only given when the clamping jaws are closed .
  • the clamping body is an elastically deformable band, the band being fastened on the one hand to a body rotatably mounted at the inner end of the clamping jaw and on the other hand to a displacement body connected to the displacement drive.
  • the clamping body is an elastic band which is mounted at a distance from its one end on a body rotatably mounted on the jaw of one pair of jaws and at a distance from its other end on a body rotatably mounted on the equilateral jaw of the other pair of jaws rests, and the length of the band between the rotating bodies so dimensioned that the band presses the bag tightly against the tubular body after tightening.
  • the clamping bodies with the clamped sack are pulled off against the force of tension springs, i.e. If the displacement or trigger drive is interrupted and / or the displacement body is connected to this drive, the elastic bands are automatically returned to their starting position, i.e. withdrawn their position at the beginning of the deduction process.
  • the distance of the support surface of the rotatable body carrying the elastic band from its axis of rotation increases towards the inner end of the band. This ensures that with the progressive withdrawal movement of the bag wall, the innermost clamping point of the clamping body even extends inwards, i.e. moves to the elastic tubular body. As a result, the seal is improved precisely at the critical, diametrically opposite positions in which the bag is clamped.
  • sealing lugs are arranged on the outside of the elastically deformable tubular body, at least in its region that can be lowered into the sack.
  • These sealing noses which are also made of an elastically deformable material, such as rubber, are located at the two diametrically opposite withdrawal positions of the sack. In cooperation with the clamping bodies designed as elastic bands, they ensure the sealing of the gusset between the tubular body and the sack walls lying on the curved regions of the elastic bands.
  • each suction cup is arranged in the middle of a crimping jaw and the crimping surface of at least one of the two crimping jaws is convexly curved.
  • the suction cups are used in a known manner to open the opening edge of the sack in the form of a parallelogram
  • the squeezing jaws have the task of closing off the closed ring zone of the sack located below the opening edge with the in the ring zone lowered tube body from the round into a flat shape. This is achieved by moving the two crimping jaws together. Since one pinch jaw, preferably both pinch jaws, are convexly curved, a larger jaw distance remains on both sides after moving together than in the middle.
  • the inner tube body is therefore less stressed on bending at the two outer bends than when the squeezing surfaces are flat.
  • two channels remain, through which air could possibly be sucked out of the sack.
  • annular channel connected to the space between the filling tube and the elastically deformable tubular body is expediently attached, which can be connected to a dedusting device and / or vacuum source.
  • the dust-containing displacement air rising between the filling pipe and the deformable pipe body enters the ring channel and is extracted from there or first fed to a dedusting device and then blown off into the ambient air.
  • the ring channel is kept under negative pressure, so that air can penetrate into the ring channel through the slot between the filling pipe and ring channel, but dust-containing air cannot get out of the ring channel through the slot.
  • the storage and actuation device of the expansion flaps is also combined with an internally open ring channel which can be connected to a vacuum source and / or a dedusting device.
  • This ring channel surrounds the deformable tubular body, which can be lifted so far that its lower edge region, which comes into contact with the ring zone of the sack to be kept clean, reaches this ring channel and can be cleaned there of any adhering dust. This ensures that dust particles do not come off the pipe during the next filling process be transferred to the ring zone to be kept clean below the upper edge of the bag.
  • the filling element is generally a tube with an internal, drivable screw and a closable discharge opening at the lower end of the tube.
  • the tube is expanded at the upper end to form a container through which the screw passes.
  • the container is also lowered when the filling element is lowered.
  • the tube of the filling element passes through a stationary container and is provided with an opening through which the tube interior is connected to the container when the tube is lowered into the filling position. In this embodiment, the container is no longer lowered and raised with the filling tube, which reduces the weight to be moved.
  • the connecting opening in the tube can be arranged such that the tube interior is connected to the container only when the tube is lowered into the filling position, so that filling material can enter the filling tube when off the tube withdrawn from the sack, however, this connection is interrupted.
  • the filling device shown for the bag 1 comprises in a known manner two diametrically opposed pairs of jaws 2, 3 and two kinematically coupled with the jaw pairs, arranged approximately in the same plane Nete, but offset by 90 ° squeeze jaws 4 and 5.
  • suction cups 6 and 7 are integrated in the center.
  • the bag which is initially in a flat position and is drawn into the filling position, is grasped in the side gusset area by the pairs of jaws 2 and 3 and is opened in a parallelogram shape by the suction pads 6 and 7, which lie opposite one another on the outside of the bag, just below the edge of the opening.
  • the device further comprises two vertically movable spreading flaps 8 and 9 which can be pivoted about the axes 10 and 11 at the same time and are shown in FIG. 1 in the pivoted-out position (spreading position).
  • the spreading flaps 8 and 9 with their actuating mechanism (not shown) are combined with an annular channel 12 which is open on the inside and can be connected to a vacuum generation system (not shown) and whose use is described in more detail below.
  • the device further comprises a vertically movable tubular body 13 made of an elastically deformable material, in particular rubber, which can be deformed, in particular flattened, under the action of sufficiently strong forces.
  • the tubular body 13 is detachably connected at its upper end to an annular channel 14 which consists of a dimensionally stable material.
  • the ring channel 14 can also be connected to a vacuum source or a cleaning system and serves to extract the dust-containing air displaced from the bag 1 during the filling process.
  • the filling element shown in the raised, closed state essentially comprises a filling tube 15 with an opening funnel 15 a at its lower end, a screw 16 driven by an electric motor (not shown) in the tube 15 and a cone 17 closing the opening of the filling tube 15 and 2 show the gusseted bag 1 held by the jaw pairs 2, 3, the opening of which has taken on an approximately circular shape through the immersed round expansion flaps 8, 9.
  • the pipe section 13 is also lowered so far that its lower end 13 a dips within the expansion flaps 8,9 in an upper ring zone 1 a of the bag 1.
  • FIGS. 3 and 4 show this device after the spreading flaps 8, 9 have been withdrawn again from the bag 1.
  • a ring zone 1 a below the opening edge of the bag 1 is now on the inside of the lower end 13 a of the tubular body 13.
  • a support ring 35 is now inserted downward into the tubular body 13 approximately to its lower edge.
  • the outer diameter of the support ring 35 is only slightly smaller than the inside diameter of the tubular body 13, so that the lower region 13 a of the tubular body 13 is supported against deformation, in particular indentation.
  • the support ring 35 shows the support ring 35 in the raised position and dashed lines in the lowered position, in which it fulfills its support function for the tubular body 13.
  • the support ring 35 is moved by means of four arms 36 which are guided in a guide 37.
  • the support ring is raised and lowered pneumatically and is controlled centrally. The spaces between the arms 36 are required for the evacuation.
  • the filling member 15-17 is withdrawn from the bag 1, as shown in FIG. 5. Then the support ring 35 is lifted out of the tubular body 13. Now the two pinch jaws 4, 5 are moved together from the position shown in FIG. 4 to the position shown in FIG. 5, the ring zone 1 a of the sack 1 being pressed flat with the inner end 13 a of the tubular body 13, as shown in FIG. 5 and 7 can be seen and will be explained in more detail below.
  • FIG. 8 shows such a transport clamping jaw 18 in section.
  • the counter-jaw 19 is designed in the same way as the clamping jaw 18 shown.
  • Two jaw parts 39 and 40 are attached to the jaw body 38 in a longitudinally displaceable manner one behind the other in the longitudinal direction.
  • the longitudinal stroke of both jaw parts 39.40 is 10 mm, for example.
  • the jaw parts 39 and 40 are held in the position shown relative to one another by springs 41, 42. Due to external forces, the jaw parts 39 and 40 can simultaneously be displaced outward against the forces of the springs 41 and 42, ie they can be moved apart.
  • the external force is exerted by a Bowden cable 43, which acts on a two-armed lever 44 with pivot axis 45. Since the lever arm of the two-armed lever 44 lying opposite the attack of the Bowden cable rests against the inner end of the jaw part 40, the jaw part 40 is displaced outwards when the lever 44 is pivoted counterclockwise, ie to the right in FIG.
  • the lever 44 is connected to a second, two-armed lever 47, which is pivotable about the axis 46, by means of a joint 48.
  • the lever arm of the two-armed lever 47 opposite the joint 48 lies against the inner end of the jaw part 39.
  • the articulated coupling of the two levers 44 and 47 brings about a simultaneous scissor-like movement of their lower lever arms which abut the inner ends of the jaw parts 39, 40.
  • the Bowden cable 43 and the springs 41, 42 thus bring about a simultaneous outward or inward movement of the two jaw parts.
  • Both jaw members 39 and 40 have in their outer regions a coating of a harder rubber 49 and 50 and in their inner portions, a coating of soft rubber 51 or 52.
  • the transport clamping jaws 18 and 19 Since in, in one form of the flattened bag edge 1a according to Figure 7 due to the curvatures In the areas adjacent to the clamping jaws 2 and 3, the transport clamping jaws 18 and 19 would usually hold the sack in a wrinkled manner, the sack is tightened by the transport clamping jaws 18 and 19 when the jaw parts 39 and 40 move apart by the tightening stroke of, for example, 2 ⁇ 10 mm.
  • the sack is gripped in the side gusset areas by the harder rubber layers 49, 50 and smoothed at least in the area of the soft rubber layers 51, 52, so that the sack walls finally lie on one another without creases and the sack can be welded closed without interference.
  • the squeeze jaws 4, 5 and the pairs of clamping jaws 2, 3 open, so that the opening edge of the sack is released with a clean ring zone 1 a on the inside and the lower end 13 a of the tubular body 13 is no longer clamped.
  • the tubular body 13 again assumes its cylindrical shape and is raised, its lower end 13 a moving into the annular channel and being freed of any dust which may be adhering to it on the outside by the negative pressure prevailing there.
  • the sack 1 can now be moved into the welding station by means of the transport clamping jaws 18 and 19 and the bottom-side sack chair (not shown), where the head weld seam is applied in the area of the dust-free ring zone 1 a .
  • Figure 6 shows a horizontal section along the line VI-VI of Figure 3, with the filling member is omitted. From Figure 6 it can be seen that the clamping jaws 2, 3 are covered with an elastic band 21 and the sack 1 is clamped between the clamping jaws in the opposite side gusset areas.
  • the bands 21 of a pair of jaws 2 or 3 are brought apart at their inner ends, so that there is good guidance of the bag material in the extraction areas between the tubular body 13 and the jaw pairs 2 and 3.
  • the crimping jaws 4 and 5 have a convexly crimping surface 4 a and 5 a .
  • the curvatures have the result that the pinched end 13 a of the tubular body 13 is not subjected to excessive bending stress when the pinch jaws 4 and 5 move together in the areas of greatest curvature, and the service life of the tube piece 13 is thereby extended.
  • small channels 22 remain in the loop areas, through which a probe for extracting air can optionally be inserted into the sack (FIG. 7).
  • FIG. 9 schematically shows a pair of jaws 2 or 3 on an enlarged scale.
  • Each jaw carries a clamping body 21 in the form of an elastic band.
  • the band 21 is fixed near its inner end, ie the end adjacent to the tubular body 13, on the surface 26 a of a rotating body 26, which is rotatably mounted about an axis 29. Near its outer end, the band 21 is selectively attached to the surface 27 a of a displacement body 27.
  • the tape 21 can be attached to the bodies 26 and 27, for example by vulcanizing, gluing or the like.
  • the rotating bodies 26 are held under the action of the tension springs 28 in a maximally pivoted position, which is not shown in FIG. 9.
  • the clamping jaws In this position of the body 26, the clamping jaws partially grasp the side folds 1 b of the sack when it is clamped.
  • the side gusset area 1 b partially pinching elastic bands 21 of both jaws 2 by a schematic only table shown displacement drive 25, in particular a pneumatic piston / cylinder unit, pulled radially outwards.
  • the displacement bodies 27 are displaceably mounted on guide rods 32 and connected to swivel rods 33, the ends of which are displaceably guided on two rods (not shown) and are moved simultaneously and in parallel by the drive unit 25 via the linkage 24.
  • the rotatable bodies 26 fastened to the inner ends of the belts 21 pivot counterclockwise (right) or clockwise (left), the side fold 1b of the sack being pulled off by the belts 21. Due to the shape of the rotatable body 26, the tapes 21 approach with increasing pivoting of the nose 13 b formed on the tubular body part 13 a , so that the gussets 23 , 24 are reduced and finally completely sealed.
  • the bag comes to the elastic tubular body part 13 a sealing contact.
  • the springs 28 pivot the rotary body 26 back into their starting position, the elastic bands 21 being moved inwards again, ie towards the tubular body 13 and the side fold of the sack is partially released.
  • This device thus causes the temporary tightening of the edge of the bag 1 a around the lower part 13 a of the tubular body 13.
  • the container 31 of the filling member is molded onto the upper end of the filling tube 15 and consequently has to be lowered and raised with the filling tube
  • the container 31 in the embodiment according to FIGS. 10 and 11 is stationary.
  • the filling pipe 15 with the screw 16 is vertically displaceable in a shaft 30 attached to the side of the container 31.
  • the shaft 30 is open in the lower region relative to the container 31, and the filling tube 15 has an opening 15 d in the upper region towards the container 31, through which the interior 15 c is connected to the interior of the container 31 when the filling element is lowered.
  • the advantage of this embodiment over the 5 is that the container 31 with its contents does not follow the vertical movements of the filling member 15-17.
  • the clamping bodies of the two equilateral clamping jaws of the two pairs of clamping jaws 2 and 3 are designed in the form of a single elastic band 21.
  • the straps 21 (not shown) initially only lie loosely subtracted from the scope and thus tightened.
  • the sack 1 is pressed tightly against the tubular body 13.
  • the course of the belts 21 when the rotating bodies 26 and 26 are in parallel is shown in dashed lines for one jaw of the jaw pairs 2 and 3.
  • the tapes have a cross section of 40 mm x 6 mm, for example, and are reinforced with fabric inserts.
