  • This invention relates generally to a device for automatically forming a pouch, filling and packaging the pouch by use of a heat sealable film as a pouch material in the state of the film being folded in half longitudinally thereof, the material to be filled being mainly powder, grain and tablets, and more particularly to a high speed packaging device designed to effect vertical sealing and filling of a large number of pouches made of the film at the highest speed possible within the function of the device, with no restriction being laid on the time required for sealing or for filling the pouch by the application of one sealing-filling device.
  • an automatic pouch forming, filling and packaging device of the type described above has been classified into two kinds in accordance with the type of sealing method, one kind being the method by which to continuously feed a heat sealable film and the other being the method by which to intermittently feed the film.
  • the former is a type wherein the film is intermittently supplied to a plate type sealing device placed in a specified position (a type of method in which the film folded in half longitudinally thereof is clamped and pressed into seal) and wherein supply of the film is stopped while the film is being sealed and wherein, upon completion of the sealing, a material to be filled is poured and, upon completion of the pouring, the film is further transferred.
  • the method described requires a very long time in the completion of one packaged pouch, because the time necessary for filling and packaging one pouch is a total of time for sealing, time for filling and time for feeding the film, while on the other hand the latter has recourse to the use of a rotary roll type sealing device, wherein the film can be supplied during the sealing thereof and a material can be filled even while the film is being sealed but wherein the film feed speed cannot be increased over the time which takes longer either in sealing or in filling. Namely, the feed speed of film is determined depending upon the time required either for sealing or for filling.
  • the former i.e. the plate type sealing device takes slightly more time than the latter i.e. the rotary roll type sealing device, but the former has the advantage that the pouches produced are free from defects such as pinholes.
  • the time required for forming and filling the pouch by the aforestated both methods is regulated either by the time for sealing or by the time for filling or by both ofthe time for sealing and filling, and unless the sealing time and filling time are reduced, production per unit time cannot be increased.
  • a primary object of this invention therefore is to provide a high speed packaging device that is excellent in productivity in that the device can effect high speed film feed with no restriction either in time required for sealing or in time required for filling.
  • Another object of the invention is to provide a high efficiency high speed packaging device that enables vertical sealing and filling ofa pouch with the material as aforedescribed at substantially the same time within a certain range of arc of one rotary drum by a rotary sealer and a rotary feeder (hereinafter called a rotary sealing-filling device) combined with one rotary drum.
  • Still another object of the invention is to provide a high speed packaging device that facilitates the production of a quality article free from defects such as pinholes in the vertical sealed portions in spite of high productivity of the device by the application of the platetype sealing device as the aforestated rotary type sealing device.
  • Still further object of the invention is to provide a high speed packaging device capable of effecting film feed, vertical sealing, filling of a material and top sealing on an all-automatic and continuous basis.
  • Yet further object of the invention is to provide a high speed packgaing device that enables precise filling operation and rarely makes wrong dropping of the material to be filled in filling a sealed pouch with the material through a filler spout.

  • the rotary sealing-filling device B vertically seals the film which has been previously folded in half longitudinally, at regular intervals and fills a pouch made of the thus folded and sealed film with a measured quantity of specified mate rial.
  • Means C horizontally seals the top edge of the filled pouch provided by the means B and may include. where necessary as a means added to the means C. a rotary cutting means D for cutting the vertically sealed portions of the filled pouches into individual pouches.
  • the numeral 1 designates a rotary shaft supported on a frame 2, the shaft being adapted to be continuously driven by a drive means not shown through a worm wheel 5 mounted on the lower portion of the shaft 1.
  • a rotary drum 4 On the top of the shaft 1 is fixed a rotary drum 4, on the circumference of which a plurality of plate type freely closable and openable sealers 6 (l6 sealers are present in the illustrated embodiment) are equally spaced.
  • Each of the sealers 6 comprises an L-shaped fixed piece 6b spaced along the entire circumference of the rotary drum 4, each movable piece 6a is pivotally mounted by a hinge 6c on the ends of the fixed piece 6b so that piece 6a can freely open and close, and heating plates 6h and 6h are disposed on the opposed surfaces of both pieces 6b and 6a.
  • Movable piece 60 is constructed in such a manner that when piece 6a travels along a rail 7, it stands up in closed relation with respect to the fixed piece 6b, but when the piece 6a is disengaged from the rail 7, it turns upside down into opened relation with respect to the fixed piece 6b.
  • sealers 6 are rotated together with rotary drum 4 and effect heat sealing in the range of about half of the locus of movement described by the rotation of drum 4 but do not seal beyond the range.
  • a rotary filler utilizing the rotary drum 4.
  • the rotary filler comprises a hopper 3 disposed immediately above the rotary drum 4 for supplying a measured quantity of the material with which the pouch is to be filled.
  • Spouts 13 are lowered into vertically sealed pouches to fill them with the material dropped from the openings 10 of hopper 3.
  • Hopper 3 supplies a measured quantity to each pouch. It is rotated by rotating shaft 19 independently of the rotating shaft 1 as shown in FIG. 2.
  • Hopper 3 is cylindrical in shape, has a bottom 31 (FIGS. 1 and 2) and is supported rotatably on a support shaft 21 connected to the frame 20. On the outer circumference of the hopper 3 is provided a gear 22, and a pinion 23 that meshes with the gear 22 mounted on the upper portion of the rotating shaft 19 which is connected by a chain to rotating shaft 1.
  • Hopper 3 is provided along the circumference thereof at the bottom 31 with openings 10 of a predetermined size that are opened on the side of sealers.
  • Blind plate 11 is independently and fixedly disposed on the underside of the bottom 31 of hopper 3.
  • the openings 10 are automatically opened and closed, and are adapted to be opened only when the openings 10 are positioned in the opened area of blind plate 11 during the cycle of operation during which the sealers 6 are closed.
  • a scraper 12 is fixed to the frame and extends into the hopper 3. Scraper 12 is designed to fill the openings 10 fully with a material by rotation of the hopper 3, while the openings 10 are moving from the position in which they are opened to the position in which they are closed.
  • the spouts 13 for filling sealed pouches with the material from the openings 10 are rotated and raised along the circumference of the rotary drum 4 in the following manner.
  • a plurality of spring seats 132 are spacedly and vertically fixed to the inside of the rotary drum 4, and shafts 133 are slidably and vertically inserted through the spring seats 132 and cam followers 15 are connected to the lower ends of the shafts 133.
  • the cam followers 15 may be integral with shafts 133.
  • Spring 16 is compressively loaded between each of the cam followers 15 and each of the spring seats 132 so as to constantly impart depressing force to the cam follower 15.
  • the cam follower 15 is caused to move on the end cam 14 fixed to the rotating shaft 1 so as to make it possible for the spout 13 to make circular and vertical movement. Furthermore, spout 13 is designed so that the folded film 82 nontangentially contacts spout 13 by swinging the spout outwardly from the locus of circular movement at its junction with film 82. Spout 13 is moved down from above the folded film to the upper open edges of the folded film before the folded film is fed tangentially from the rotary drum, is caught by the sealers and brought into a fully closed shape.
  • the spout is inserted into the interior of the film 82 so that the spouts may be moved linearly together with the film 82 to a point of contact between the film 82 and the rotary drum 4. Accordingly, there is no need to expand the edges of the opening of the folded film widely enough to permit the insertion of the spouts 13 into the opened edges by application of a suction nozzle or the like nor is there any possibility of the film 82 coming into collision with the spouts 13 at a junction between the two, with the result that the spouts 13 are allowed to be lowered inside the film 82 automatically and smoothly.
  • a deflection plate 136 fixed to the side of support shaft 21 as shown in FIG. 4 and disposed in opposed relation with the circle 0 of locus of movement of the hooked rod of the arm 134 of the spout.
  • Shaft 133 is twisted by the rod 135 bearing against the deflection plate 136 to cause the spout 13 to swing partially outwardly from its circle 0 of locus of movement so that film 82 joins nontangentially spout I3 and the end cam 14 is allowed to move down gently from such nontangential junction toward the position of point of contact.
  • top sealing members C have a variable speed gear (not shown) in order to provide the same peripheral speed between the top sealing member C and film 82.
  • the contoured height of cam 14 is a factor in determining the elevatable stroke of the spouts in combination with the rotational movement of spouts 13, but it is possible to make hopper 3 as close to rotary drum 4 as possible by positioning hopper 3 to make its measured supply of a material, in eccentric relation with respect to rotary drum 4.
  • the uppermost elevatable position of spouts 13 may be set on the side of hopper 3 but not below hopper 3 as shown in FIG. 2.
  • hopper 3 is a disk smaller in diameter than the rotary drum 4 (as shown in FIG. 1).
  • the axis of hopper 3 is eccentric with respect to rotary drum 4. In this eccentric relation between the two, material is dropped from the hopper within a certain range of rotational movement relative to spouts 13. As shown in FIG.
  • the locus of rotational movement 0 of openings generates an inscribed circle with respect to the locus of rotational movement 0 of spouts 13, and furthermore, the distance 1 between the respective centers of spouts 13 is so established as to be equal to the distance l between the respective centers of openings 10, with the result that when the rotation of rotary drum 4 and hopper 3 brings spouts 13 and openings 10 into the sector range R in FIG. 3, spouts 13 and openings 10 are brought into vertical alignment with each other within the range R and material drops from openings 10 into funnels 131 of spouts 13.
  • the heat sealable film that forms a pouch is folded longitudinally in half (into a V-shape) in such a manner that the opened edges of the folded film face upward.
  • a device A that feeds the heat sealable film thus folded from the direction of one tangent of rotary drum 4 is represented as a bugle-shaped folding guide 9 that gradually folds the heat sealable film 81 fed from a film roll 8 as shown in FIG. 1.
  • the film 8 is folded successively longitudinally in half (in a V-shape) by bringing both side edges of film 81 into engagement with both outwardly folded rear edges 91-of guide 9 and transferring film 81 along the outside surface of the guide 9.
  • the film 81 is made either of heat sealable synthetic resin or of paper having the same type of synthetic resin layer formed over the inner surfaces thereof to be brought into abutting relation with each other when the paper is folded in half.
  • the folded film 82 is fed from the position in which the movable piece 6a of the sealer 6 is opened to the sealers 6 from the direction of one tangent of the rotary drum 4.
  • the filledpouches that have finished vertical sealing by the sealers 6 and pro portioning ofthe material by the spouts 13 immediately after the vertical sealing are pulled through top sealer C.
  • Top sealer C is a known type of heat sealer capable of adjusting a pair of upper and lower heating rolls 17 and 17' by a pressure regulator 171 so as to freely regulate rolling pressure.
  • the filled pouches 83 that have vertically sealings 84 are clamped between the rolls 17 and 17 on the upper open edges thereof thereby forming filled pouches 85 sealed on three sides.
  • the rolls 17 and 17' concurrently serve as take-up rolls for the folded film as previously described.

  • numeral 25 designates chain sprockets; 26 a bearing; and 38 designates a regulating means that regulates the maximum open position of the movable piece 6a.
  • the device according to the present invention operates as follows.
  • Film 81 unrolled from film roll 8 is folded longitudinally in half progressively by folding guide 9 and is fed along the outer surfaces of guide 9 from the direction of one tangent of rotary drum 4 to sealers 6.
  • Sealers 6 rotate while they are pressing and clamping folded film 82 so as to divide the film 82 at equal spaces at right angles with the longitudinal direction of the film 82 in accordance with rotation of drum 4 to produce vertical seals 84.
  • Spouts 13 are gradually moving down from above to the upper open edges of film 82 before the sealers 6 clamp and press film 82, and insert the lower ends thereof into film 82 by the operation of end cam 14.
  • Sealers 6 clamp film 82 on both sides of spouts 13, press and heat seal the film 82.
  • hopper 3 is mounted eccentrically with respect to rotary drum 4 and the locus of rotational movement 0 of the openings 10 is brought into the relation of inscribed circle with respect to the locus of rotational movement 0 of spouts 13, and both loci O and 0 include no such portion outside the sector range R as will bring the loci O, and 0 into alignment with each other. Accordingly, the path which permits elevation of spouts 13 is obtained on the lateral side of hopper 3 except for the portion wherein both loci O, and 0 are in the relation of an inscribed circle with each other as shown in FIG.
  • a chain of pouches 83 which are sealed on the two sides thereof and which are filled with material is transferred tangentially of the opposite side of rotary drum 4 and the upper opened edges of the film 82 are successively horizontally sealed by a roller type top sealing means 17 to thereby complete a chain of filled pouches 85 which are sealed on the three sides thereof. Thereafter, the continuous chain of formed, filled, and sealed pouches 85 is cut off by a rotary cutter into individual packages.
  • sealing of the film at a plurality of points and filling at a plurality of points are parallelly and simultaneously carried out by a plurality of sealers 6 and spouts l3 and accordingly, one rotation of rotating shaft produces 16 filled packages as illustrated in the drawings.
  • the device for producing formed, filled, and sealed pouches makes it possible to dispense with the time required for sealing by the sealers, effect filling and sealing simultaneously, make the time for sealing overlap the time for filling, and seal and fill the film while the film is being transferred; and because the present invention seals also other parts at the same time by the successive sealers while sealing one part of the film, the device of the present invention can carry out continuous film feed, filling, and packaging in spite of the fact that a sealing means like a plate type sealer which performs intermittent operation is used. Accordingly, film feed can be increased in speed regardless of the time required for sealing or the time for filling.
  • production of filled pouches per unit time depends upon the speed of the film feed, but the present device makes it possible not only to produce a large number of packages by one action even if film feed is constant, independently of the time for sealing and the time for filling which govern the feed speed, but also to increase the feed speed itself.
  • the production per unit time is far superior to that attained by the known types of devices.
  • a plate type sealer is used in combination with the rotary drum and because sealing is effected during rotation of the rotary drum more time can be spared for sealing notwithstanding'this high productivity, with the result that quality packages free from defects such as pinholes on the sealed portions can be obtained.
  • the distance between the hopper and the spouts can be reduced as much as possible, with the result that not only correct dropping of material from the hopper into the spouts is insured but also there is no loss in amount of material during supply nor adhesion of the split material to other members.
  • the respective numbers of rotations of the rotary drum and hopper can be increased to a high speed of 400 rpm/min at maximum which has never heretofore been attained.

  • Shaft 28 is caused to make circular movement, but roller 35 is caused to swing out slightly outwardly from the circular movement of shaft 28 in the area 361 in which cam 36 is caused to swing out as above, to thereby twist shaft 28 outwardly by 0 and thus cause spouts 13 to swing outwardly.
