Definitions

  • the present invention relates to an improved packaging machine. More particularly, the invention pertains to an improved method and apparatus for continuously forming, filling and sealing packages while linked together to a continuous web of material.
  • packaging machines are categorized into horizontal and vertical machines depending on the general direction of movement of a continuous web of material.
  • the present invention relates to horizontal packaging machine and is designed to operate in a continuous manner.
  • the method and apparatus of the present invention differs from those previously proposed and employs a number of novel features that render it highly advantageous over the prior art.
  • the invention relates to horizontal packaging machine and is designed to operate in a continuous manner utilizing a continuous web of film material for automatically forming, filling and sealing packages.
  • Another object of this invention is to provide an improved method and apparatus for manufacture of filled packages from a polyethylene material to provide for especially inexpensive packaging costs.
  • Another object of this invention is to provide an improved method and apparatus for manufacture of filled packages having a pull-apart horizontal seal for easy opening of a filled package.
  • Another object of this invention is provide pouches that can be filled to a greater extent than traditional pouches so that the pouches are bulged in shape.
  • Still another object of this invention is to provide a new method and apparatus for forming vertical seals in the web to provide a series of pouches only partially severed by the vertical seals from one another preparatory to filling with only upper portions of each being connected with adjoining pouches during a filling operation.
  • Still another object of this invention is to provide a packaging machine for continuously forming filled pouches with a new and improved pouch opening station using suction applied to opposite outer surfaces of the opposed sidewalls of each pouch to open the sidewalls of the pouch to facilitate filling.
  • Still another object of this invention is to provide a new method and apparatus for holding open pouches in engagement with a filling funnel during filling.
  • Yet another object of this invention relates to new type of packaging machine for continuously forming filled pouches with a new type of trimming station whereby the filled and sealed pouches are severed from the web simultaneously as the upper portion of the web is cut away.
  • a method and apparatus of continuously forming, filling and sealing of packages with a continuous web of fusible film material includes the steps of folding the web to provide confronting sides joined along a bottom edge and sealing by training the web onto a vertical seal former having plurality of vertical sealers and progressively forming each vertical seal as the web is being continuously moved with the vertical sealer while at the same applying a low temperature sealing action to allow the area of the film being sealed to be progressively melted.
  • This process forms a series of horizontally disposed pouches severed by the vertical seals extending transversely of the web leaving sealed side edges of each pouch severed from one another with upper portions of each pouch being connected with adjoining pouches and having opposed sidewalls of each pouch unsealed along a top edge. Opened pouches are then filled prior to sealing a top portion of the opposed sidewalls of each pouch together to enclose the filled pouches. Upper portions are then trimmed from the web to simultaneously sever the filled and sealed pouches from the web.
  • the web has a surface coated with a peelable substance and the step of sealing the top edges of the opposed sidewalls of each pouch together to enclose the filled pouches provides for confronting sides coated with the peelable substance to remain separable after being sealed together.
  • the vertical seal former includes a sealing drum with a plurality of circumferentially spaced sealing wires.
  • the sealing wires electrically connected in series.
  • An electrical current being applied to the sealing drum to generate a first electrical path between a first set of sealing wires and a second electrical path between a second set of sealing wires.
  • Each sealing wire progressively moving through the first set and the second set as the sealing drum rotates.
  • pouches are opened by providing a rotating a pair of vacuum belts mounted adjacent to one another to provide an elongated channel therebetween.
  • the vacuum belts each having a plurality of equally spaced apart vacuum ports extending around an outer surface of each vacuum belt.
  • a suction force is applied through the vacuum ports of each vacuum belt when the vacuum belt travels through the elongated channel.
  • the web is then directed through the elongated channel so that each successive vacuum port is in approximate horizontal alignment with a center portion of a successive pouch to provide opening of the pouch as opposite outer surfaces of the opposed sidewalls of each pouch are progressively pulled apart by the suction force through the vacuum port.
  • the present machine 10 is horizontal type packaging machine and is capable of producing packages 12 at a high rate of production.
  • the packages 12 are produced from a continuous strip or web of film material 14 or from several continuous webs of film materials as desired.
  • the web is formed of polyethylene film material, which provides an inexpensive packaging material. Additionally, the web may be pre-printed.
  • polyethylene should also include any polyethylene type materials having similar properties and characteristics, which are known as fusible film material.
  • the web to be use in the this packaging is coated with a peelable substance, such as ZEELON 318 which is a coextruded cast HDPE/LDPE/EVA film having gauge of 1.75 mil.
  • a peelable substance such as ZEELON 318 which is a coextruded cast HDPE/LDPE/EVA film having gauge of 1.75 mil.
  • the peelable substance When the peelable substance is used during in the sealing process it enables the laminations of the film to be peeled apart. The separation can involve the separation of one coating on one lamination from the other coating on a confronting lamination. With other types of peelable film, the film stock itself is severed so that the separation would not necessary occur strictly between confronting layers of peelable coating. Thus, the characteristics of the peeling action depend on the coating and material used. As will be later described, the use of peelable substance allows for the creation of a separable or pull-apart seal which is highly desirable for packages filled with powder or other materials to allow for easy opening.
  • a coiled roll of the continuous web 14 of film material is mounted for rotation on a frame 16.
  • a suitable strip plow 18 is connected to the frame 16 for folding the web 14 to provide confronting sides 20 joined along a bottom edge 22 (FIG. 1) of the web 14.
  • the web 14 is coated with the peelable substance as above-described.
  • a strip knife 24 of conventional type is connected to the plow 18 for severing the bottom edge 22 of the web 14 to produce two separate confronting sides 20 having confronting surfaces of coated substance.
  • the confronting sides 20 are then directed through a horizontal sealer 26, which is a hot bar heat sealer of conventional type.
  • a temperature of approximately 160° F. used with ZEELON 318 film having a gauge of 1.75 mil produces a low temperature or peel apart seal 28 sufficient for sealing the confronting sides along the bottom edge 22 so that the confronting sides coated with the peelable substance can be peeled apart, as illustrated in FIG. 15.
  • the use of a peel apart seal 28 along a bottom edge 22 is highly advantageous when packaging products such as food powders. During a later occurring filling process, the surfaces of the web 14 may become dusted with a thin layer of this product which would weaken the low temperature seal 28. However, when packaging products such as nuts or bolts, this peel apart seal 28 may be applied along a top edge 30. When a peel apart seal 28 is not desired, the above described strip knife 24 and horizontal sealer 26 are not needed and the originally formed V-shaped bottom edge 22 replaces the need for the seal 28.
  • a guide roller 32 directs the web onto a vertical seal former 34.
  • the vertical seal former 34 has a commutator or sealing drum 36 mounted for rotation to table 38.
  • the sealing drum 36 has a plurality of elongated circumferentially spaced vertical sealers 40 mounted to an outside surface of the sealing drum, as best illustrated in FIG. 5.
  • each vertical sealer 40 has a sealing wire 42 extending longitudinally and mounted to an outer sealer surface 44 of the vertical sealer 40. Each sealing wire 42 being in pressing engagement with the web 14 which extends around the sealing drum 36.
  • the sealing wires 42 are pressing against the web 14 to progressively form vertical seals 46 as the web 14 is being continuously moved with the vertical sealer 40 while at the same time applying a low temperature sealing action to allow the area of the film being sealed to be progressively formed or cooked.
  • the vertical seals are formed, the confronting sides 20 of the web 14 are melted together along the sealing wire 42, with the sealing wire then melting through the web 14 to have formed a vertical seal 46 along each adjacent side of the sealing wire 42.
  • a series of horizontally disposed pouches 48 have been produced. The pouches 48 are partially severed from one another by the vertical seals 46 extending transversely of the web 14.
  • each pouch 48 is severed from adjoining pouches with upper portions 52 of each pouch 48 being connected with adjoining pouches and having opposed sidewalls 54 of each pouch unsealed along a top edge 56.
  • the vertical seals 46 extend from a bottom edge 58 of the pouch 48 to the upper portion 52 of the pouch 48 and do not extend transversely across the entire web surface so that each pouch 48 will still be connected with adjoining pouches 48.
  • the vertical seal former 34 includes a circular inner contact wheel or ring 60 connected to the sealing drum 36 connected for rotation therewith.
  • the inner contact wheel 60 has a plurality of circumferentially spaced electrical contact points 62.
  • these points 62 are rectangularly shaped brass inserts that are mounted along a perimeter 66 of the contact wheel 60.
  • a pair of spaced apart electrical carbon contact brushes 68 of conventional design are mounted to a plate 70 which is connected to the table 38.
  • the brushes 68 are in pressing electrical engagement with the inner contact wheel 60.
  • the brushes 68 are connected to a positive and negative terminals of a power supply (not shown) for producing an electrical current through the brushes 68.
  • the contact points 62 and sealing wires 42 are electrically wired in series with a plurality of wire leads 71 connected by conventional methods to provide a first electrical path between a first set 72 of sealing wires 42 and contact points 62 and a second electrical path between a second set 74 of sealing wires 42 and contact points 62.
  • each sealing wire 42 will progressively move through the first set 72 and then the second set 74 as the sealing drum 36 rotates. Furthermore, since the contact points 62 are contained in segments, the electrical circuits formed through the first and second electrical path will have pulsating effect as the brushes 68 cross over from one contact point 62 to another.
  • the first electrical path is an electrical path of least resistance and has a greater electrical current than the second electrical path. This is an important feature of allowing the vertical seals 46 to form slowly with progressively increased temperatures. Through experimentation, it has been found that an electrical current of approximately 35 volts works well.
  • the first electrical path will generally have an electrical current in the range of 2 to 5 amps, while the second electrical path will have an electrical current in the range of 0.5 to 1.5 amps.
  • the sealing wires 42 and contact points 62 are wired together. There is an equal number of contact points 62 with sealing wires 42. Therefore, by changing the wiring configuration, it is possible to disconnect certain sealing wires 42 so that the size of the pouch 48 can be adjusted.
  • FIG. 7 illustrates the general concept of wiring each sealing wire 42 to a contact point 62 so that each sealing wire 42 along the sealing drum 36 will be energized. Therefore, the width of a pouch 48 will be determined by the horizontal distance between sealing wires 42.
  • the wiring concept is provided for wiring every other sealing wire 42 so that width of the pouch 48 would be approximately double.
  • the circuitry to accomplish the electrical wiring and electrical features previously described will be clear to those skilled in the art from the present disclosure. Alternative methods could be used to heat the wires, if desired, instead of the preferred form as shown and described herein.
  • a TEFLON or elastic rubber coated belt 76 is guided and driven by rollers 78, 80, 82, and 84 for moving belt 76 in synchronized movement with the sealing drum 36 so that the belt 76 will press against the sealing drum 36 with the web 14 therebetween to provide support for the web 14 during the vertical sealing process.
  • a press roller 86 is mounted for rotation to the table 38 in pressing engagement against the belt 76 which is against the circumferential outer surface 88 of the sealing drum 36 to aid in the severance of the vertical seals 46.
  • roller 90 directs the web 14 from the vertical seal former 34 to a pouch opening station 92.
  • the pouch opening station 92 includes a rotating a pair of vacuum belts 94 extending between front rollers 96 and back rollers 98.
  • the front rollers 96 have annular channels 100 for fixed positioning of the vacuum belts 94.
  • a plurality of sprockets 102 are connected to the front rollers 96 within the channels 100 for engaging sprocket holes 104 contained in the vacuum belt 94 to prevent belt slippage, the importance of which will become clear from the following disclosures.
  • Confronting portions 106 of adjacent sections of the vacuum belts define an elongated channel 108.
  • the vacuum belts 94 each having a plurality of equally spaced apart vacuum ports 110 extending through an outer surface 113 of each vacuum belt 94.
  • a pair of vertically aligned vacuum ports 110 are provided in a horizontally spaced apart manner, as described later.
  • a pair of suction channels 112 are provided.
  • the channels extend between the front roller 96 and the back roller 98 and are adjacent to an inside surface 114 of the vacuum belt 94.
  • the channels 112 have a pair of parallel elongated slots 116.
  • the slots 116 correspond in vertical alignment with the vacuum ports 110 to allow air passage therethrough, as best shown in FIG. 3.
  • a vacuum hose 118 has a first end 120 in air flowing connection to each channel 112.
  • a second end 122 of the vacuum hose is connected to a vacuum device of conventional design (not shown) to produce suction forces.
  • a vacuum device of conventional design not shown
  • Preferably, 3.0 inches of Mercury (Hg) provides a suitable pressure.
  • Each channel 112 has a leading end portion 124 (FIG.
  • the leading end portions 124 contain the elongated slots 116 as well as a slot 126 for allowing the sprockets 102 to rotate without engagement with the leading end portion.
  • the suction forces travel through the vacuum ports 110 of each vacuum belt 94 when the vacuum belt 94 travels through the elongated channel 108.
  • Confronting surfaces 130 of the vacuum belts 94 define a narrow channel 132 for first directing the web 14 through when entering the pouch opening station, as shown in FIG. 8.
  • each successive vacuum port 110 is in approximate horizontal alignment with a center portion of each successive pouch 48 to facilitate opening of the pouch 48 as opposite outer surfaces of the opposed sidewalls 54 of each pouch 48 are progressively pulled apart by the suction force being applied from the vacuum ports 110.
  • An air jet device 138 of conventional design is provided to aid in the separation of the opposed sidewalls of each pouch 48 by directing a stream of air at the upper portions 52 (FIG. 5) of the pouch 48 as the pouch is being first opened as passes though the narrow channel 132 (FIG. 8).
  • the distance between the vacuum belts has increased to correspond to the distance that opposed sidewalls are separated. It is important to note that the horizontal spacing between the vacuum ports will be a less amount than the width of the pouches to compensate the decreased width of a pouch 48 when the sidewalls are separated. For example, it has been found that 4.0 inch spacing between vacuum ports is required when the width of the pouches is 4.5 inches.
  • the sealed side edges 50 of each pouch 48 being severed from adjoining pouches 48 is an important improvement over the prior art, shown in FIG. 18, where the sealed side edges 50 are connected to adjoining pouches 48.
  • the pouches can filled to a greater extent allowing the pouches to take on bulged shape or appearance, as shown in FIG. 17. Since the pouches 48 may filled to this extent, the width between vertical seals during the sealing process must be larger than the size of package required by the end user because additional film material must be allowed to compensate for this bulging.
  • the pouch 48 is being shown full for illustrative purposes, recognizing that on the line 3-3 of FIG. 2 that pouch 48 would be empty.
  • an underlying conveyor 140 is provided for supporting a bottom portion 142 of the full pouch.
  • the conveyor 140 is conventional design and is timed for synchronized movement with the web 14.
  • the conveyor 140 is replaced with a bag shaking assembly 200.
  • the bag shaking assembly creates a vibratory action that engages against a bottom portion 202 of the pouch 48 to settle the product into the bottom of the pouch as the pouch is filled. Settling of the product allows for effective filing of the pouches 48, especially in the packaging of food powder.
  • the bag shaking assembly 200 includes a flat elongated member 204 that vibratorily engages against the pouches 48.
  • the elongated member 204 is connected to a pair of downwardly extending support arms 206,207 which are eccentrically mounted to a cam assembly 208,209 of conventional design.
  • the cam assembly 208,209 is rotationally driven by a drive assembly (not shown) of conventional design.
  • the drive assembly turns the cam assemblies 208,209 as a high rate of speed to transfer eccentric or reciprocating motion to the support arms 206,207, which in turns produces the vibratory type of the action needed to assist in settling the pouch 48 contents.
  • the bag shaking assembly 200 places additional strain on the forces required to support the pouches 48. Additional strain can also be created when filling pouches 48 with a heavy product. To compensate for this additional strain, a number of options are available. For example, a larger vacuum device having increased suction abilities could by used with the vacuum belt 94, as previously described, to support of the weight of the product during this bag settling process. Preferably, mechanical clips 212 are used to assist in supporting the pouches 48.
  • a filling station 144 is provided for filling the opened pouches 48.
  • a timed volumetric distribution of powder is conveyed to an underlying conveyor 146.
  • the speed of the conveyor can be automatically timed in proportion to the speed of moving pouches.

  • the clips 212 are shown to prevent the pouch, as it is being filled, from pulling away from the funnel to thereby insure proper filing of the pouch.
  • the clips 212 are pivotally mounted to both sides 214,215 (FIG. 3) of each funnel 150.
  • the clips 212 include a hinge assembly 213 for pivoting movement and are biased with a torsion spring 217.
  • a forward end 216 of the clip 212 has a clip pad 218 for pressingly engaging an upper portion 220 of each bag side 222,223 (FIG. 3) of the pouch 48 against a respective side 214,215 of the funnel 150.
  • Each clip 212 has a curved extending arm member 224 for actuating the clip 212 from a closed position to an open position.
  • each funnel 150 is inserted into an opened pouch 48
