Definitions

  • This invention relates to the filling of flexible sacks, bags and like containers made of non-woven sheet material, and has as its primary object to provide improved apparatus for handling sacks and bags during filling which apparatus requires only slight supervision and which is therefore economical in manpower.
  • the invention provides apparatus for use in the filling of flexible sacks or bags, such apparatus comprising lifting means operable to lift a sack or bag and to present the same to a filling spout, suction means operable to open the mouth of the sack or bag, and means operable to bring about relative movement between the open sack or bag and the filling spout to engage the sack or bag with the spout for filling.
  • the said suction means may conveniently comprise a pair of suction devices adapted to engage the sack or bag on opposite sides thereof in the region of its mouth and movable relatively to one another to draw the mouth open for engagement with the said filling spout.
  • the relative movement which is then brought about between the sack or bag and the filling spout may be by movement of either or both of such elements; in a preferred form of the invention the filling spout is mounted for movement into and out of the open mouth of the stationary sack or bag.
  • one of the said suction devices may be associated with the said means for lifting a sack or bag to present it to the filler spout, so as to constitute the means whereby the said lifting means grips the sack or bag to lift it.
  • the other suction device will then be mounted so as to be engageable with the sack or bag on the side thereof opposite from that where it is already gripped by the first-mentioned suction device, once the sack or bag has been lifted.
  • the sacks or bags are supplied to the lifting means in stacks on an endless conveyor and the lifting means comprises an arm carrying a suction device and swingable about a pivotal mounting to pick up sacks or bags one by one from the top of such a stack and lift them.
  • each of the said suction devices may comprise one or more suction cups, and the suction cups of the respective suction devices will preferably co-operate in one or more pairs of axially aligned suction cups so as to achieve a symmetrical opening of the mouth of the sack or bag.
  • each of said suction devices comprises a single suction cup, the arrangement being such that said cups are disposed on a common axis and positioned to engage the mouth of a sack or bag substantially centrally of its width when in their relative positions for opening the mouth of the sack or bag.
  • each of said suction devices comprises two or more suction cups, the arrangement being such that the cups of the two devices are disposed in axially aligned co-operating pairs when in their relative positions for opening the mouth of a sack or bag.
  • each of said suction devices comprises three suction cups, the central co-operating pair of cups being arranged to engage the mouth of a sack or bag substantially centrally of its width whilst the two outer co-operating pairs of cups are arranged to engage the mouth of a sack or bag one on each side of said central co-operating pair.
  • each of the suction devices comprises three suction cups as aforesaid it is desirable that the cups of each device should be movable relative to one another as the mouth of a sack or bag is opened thereby, so as to cause such mouth to be opened to a substantially circular or oval configuration rather than a rectangular one, it being understood that when they first engage the sack or bag mouth the suction cups of each device must have their mouths aligned in a common plane.
  • the two outer cups of each suction device are connected to the central cup thereof via flexible connections which connections may conveniently include one or more flexible mounting plates for the outer suction cups.
  • said flexible plate or plates extending outwardly beyond said outer suction cups and being engageable with stop members of the apparatus when the two suction devices are moved relative to one another to open the mouth of a sack or bag, so as by flexure of said mounting plates to cause the sack or bag mouth to be opened to a substantially circular or oval configuration.
  • the apparatus of the invention is intended to find particular utility in the filling of sacks or bags made of plastics sheet material, which is of course highly flexible and as a result diflicult to handle in some respects.
  • a guide shoe will be provided to receive the mouth of the sack or bag as it is lifted into the mouth opening region, such guide shoe being arranged to define the position of the mouth of the sack or bag for opening by the said suction means.
  • the apparatus includes a pair of mechanical gripper devices operable to grip the sack or bag adjacent its mouth at two substantially opposite regions thereof once the sack or bag has been lifted by said lifting means, such gripper devices being movable towards and away from one another so as, respectively,
  • the said filling spout may if desired be secured to or movably mounted on the outlet from a storage hopper for the commodity concerned, we prefer to provide the filling sput as part of the apparatus of the invention and in a preferred embodiment it is mounted in a common assembly with the above-mentioned gripper devices, the filling spout being movable relatively to the gripping devices so as to be insertable in and withdrawable from the open mouth of a sack or bag held by such devices.
  • the said filling spout and gripper devices are mounted on a carriage which is movable between a sack or bag receiving and opening station in which the sack or bag is received from the said lifting means, has its mouth opened by the said suction means, and is engaged with the said filling spout, but at which station the said spout is displaced from the outlet from a storage hopper or other container for the commodity concerned, and a sack or bag filling station in which the said filling spout is aligned with the outlet from such a hopper for the passage of material into the sack or bag via the spout.
  • the said suction means for opening the mouth of the sack or bag may then be permanently situated at the said sack or bag receiving and opening station, as once the mouth of the sack or bag has been gripped by the gripper devices, opened, and engaged with the filling spout, it will be held open for filling without any further assistance being required from said suction means.
  • the apparatus of the invention includes a vibratory posser situated so that the sack or bag will sit on a vibrating platform thereof whilst it is being filled.
  • a posser when such a posser is provided in the preferred form of the apparatus referred to above, such posser will be situated at the sack or bag filling station so that the sack or bag will sit thereon during filling.
  • the tendency will be for its breadth to expand and its depth to contract, and the posser will therefore be mounted for vertical movement so that it may be caused to rise and thus lift the bottom of the sack or bag during filling so as to accommodate such changes in the shape of the sack or bag.
  • a novel preferred feature of a posser which may advantageously be incorporated in apparatus of the invention is that its vibratory platform may take the form of an endless conveyor.
  • Such conveyor will not of course be operated whilst the sack or bag is being filled, but once filling is complete and the sack or bag is to be moved away from the filling station the conveyor will be operated to assist in such transfer.
  • the apparatus of the invention preferably includes means for sealing the mouth of the sack or bag once it has been filled, and such means may conveniently take the form of a sewing mechanism of conventional type, or a heat sealer in the case of sacks or bags of plastics sheet material.
  • the apparatus may, however, include novel and advantageous means for transferring the filled sack or bag to such mouth sealing means, in the form of a pair of endless chain drives arranged to co-operate to grip theclosed but unsealed mouth of the sack or bag therebetween to effect such transfer.
  • endless chains extend into the sack or bag filling station and are mounted for opening and closing movement relative to one another so as to be open during the filling step but to be closable together to grip the sack or bag mouth therebetween once it has been filled and to draw the sack or bag away for sealing thereof.
  • at least one further pair of endless chain drives are provided downstream of those already mentioned to take over the movement of the sack or bag through the mouth sealing means; such further chain drives need not, of course, be relatively openable and closeable.
  • endless conveyor means will be provided on which the sack or bag Will sit throughout its movement through the apparatus after filling; such conveyor means will receive the filled sack or bag from the conveyor associated with the posser where such is provided. It is indeed desirable that suitable underneath support should be provided for the sack or bag throughout its passage through the apparatus once filling has commenced, rather than permitting the sack or bag to be suspended from the aforementioned gripper devices or endless chain drives for example; this is of particular importance when the mouth of the sack or bag is to be sealed by sewing, as the position in which the mouth is presented to the sewing mechanism must then be accurately defined and this will be diflicult if the weight of the filled sack or bag has to be supported via its mouth as it is being transferred to the sewing mechanism.
  • the various elements of the apparatus of the invention may be powered in any suitable manner, e.g. electrically, hydraulically, pneumatically or mechanically.
  • the interrelation of the movements of such elements to carry a sack or bag through the apparatus may conveniently be achieved by means of micro-switches actuated by the movements of such elements and operative to initiate subsequent operations.
  • FIG. 1 is an end elevation of the apparatus, looking downstream relative to the direction of the movement of sacks or bags therethrough during filling;
  • FIG. 2 is a plan view of the apparatus with certain parts not shown for the sake of clarity;
  • FIG. 3 is a view similar to FIG. 2 but with certain parts in different positions and also showing the elements of a sewing mechanism;
  • FIG. 4 is a view in elevation looking upstream from the plane indicated at IVIV in FIG. 3;
  • FIG. 5 is a side elevation, again with certain parts removed for the sake of clarity, looking from the left hand side of the apparatus as seen in FIG. 1;
  • FIG. 6 is a plan view of an alternative arrangement of suction means for opening the mouth of a sack or bag for filling, with the parts in one position;
  • FIG. 7 is a view similar to FIG. 6 but with the parts in another position.
  • the apparatus includes sack or bag lifting means comprising a support structure 1 carrying a swinging arm 2 mounted at 3 for pivotal movement in a vertical plane at right angles to the length of the apparatus.
  • the arm 2 carries a pneumatic jack 4 whose rod carries a further pneumatic jack 5 whose rod in turn carries a suction device in the form of a rubber cup '6.
  • the arm 2 is swingable by means of a further jack 7 carried on the support structure 1 with its rod linked to the arm 2.
  • Sacks or bags for filling are delivered to the lifting means in successive stacks 8 on the canted surface of an endless conveyor 9.
  • the illustrated apparatus is particularly intended for use in the filling of paper sacks and the further description will therefore refer to sacks of this kind where appropriate.
  • the lifting means is shown in its lowered position in full lines in FIG. 1 and in its raised position in dot and dash lines. It will be observed that the jack 4 is operable to extend the suction cup 6 to pick up a sack from the stack thereof. The jack on the other hand is operable to withdraw the suction cup when the mouth of the sack is to be opened as is explained below.
  • the lifting means is operative to lift a sack, in flat condition and with its mouth upwards, so that its mouth enters a guide shoe 10 (FIG. 1).
  • the guide shoe is stationarily mounted on a main support framework 11 of the apparatus, on which is also carried a second suction device in the form of a suction cup 12 similar to the cup 6.
  • the suction cup 12 is mounted on the rod of a pneumatic jack 13 so as to be movable towards and away from the guide shoe 10.
  • the two top horizontal members 14 of the supporting framework 11 are formed as runners and mount a carriage 15 for movement therealong lengthwise of the apparatus.
  • the carriage carries a filling spout 16 and two gripper devices each of which devices consists of a fixedly mounted gripper member 17 and a movable gripper member 18 (see FIG. 4 in particular).
  • the filling spout 16 is mounted for vertical axial movement in the carriage 15.
  • the spout is carried by a pair of pivotal arms 19 mounted on a side member of the carriage frame and such arms are pivotable by a pneumatic jack 20 on the carriage via a link 21 so as to raise and lower the filling spout as desired, the raised position 'being shown in dot and dash lines in FIG. 4.
  • the movable gripper members 18 are movable in concert by means of a pneumatic jack 22, to whose rod the grippers 18 are connected, so that the two gripper devices may be opened and closed simultaneously with each other. Moreover, the two gripper devices are mounted for pivotal movement towards and away from one another in directions lengthwise of the apparatus under the influence of a pneumatic jack 23 (FIG. 5) acting through a bellcrank lever 24 and links 25. It will be seen that expansion of the jack 23 will cause movement of the two gripper devices towards one another; contraction of the jack will move them away from each other.
  • the carriage 15 is movable along the runners 14 between a sack receiving station, which it is shown occupying in FIG. '2, and a sack filling station (FIGS. 3 and 5). Movement of the carriage is powered by a pneumatic jack 26 mounted on the apparatus frame and having its rod connected to the carriage 15 by lever arms 27 and 28 pivotally mounted at 29. In an alternative arrangement to that shown the jack 26 could be mounted at a lower level than the carriage 15, at the upstream end of the framework 11 and the lever assembly connecting the jack to the carriage arranged for movement in a vertical rather than a horizontal plane.
  • a posser 30 (FIG. 5) is situated immediately below the sack filling station and comprises a vibrator acting on a platform 31 formed by the upper run of an endless conveyor.
  • the level of the posser platform 31 is adjustable under the control of a pneumatic jack 32, between a lowered position shown in full lines in FIG. 5 and a raised position shown in dot and dash lines in which the platform surface is level with the surface of a further endless conveyor 33.
  • a pair of co-operating endless chains 34 and 35 are mounted in cantilever fashion so as to extend upstream into the sack filling station already referred to, and are drivable in unison in the direction of the arrows by an electric motor 36.
  • the supports 37 and 38 for the respective chains 34 and 35 are rotatably mounted on axes 39 and 40.
  • a lever 41 rotatable about axis 39 and secured to the mounting of endless chain 34 is pivotable about such axis by means of a pneumatic jack 42.
  • the free end of the lever 41 is formed as a toothed quadrant meshing with a similar quadrant 43 mounted for rotation about axis 40 and secured to the mounting of endless chain 35.
  • the endless chains 34 and 35 are thus movable in concert, by operation of the jack 42, between a mutually spaced condition shown in FIG. 2 and an engaged condition (FIG. 3) in which the chains co-operate to grip therebetween a sack along its top edge and to convey it downstream, i.e. from right to left as seen in FIGS. 2 and 3.
  • a further pair of co-operating endless chains is mounted immediately downstream of the chains 34 and 35 to take over the con veyance of sacks from the latter chains and to move them through a sewing mechanism indicated generally at 45 in FIGS. 3 and 5; the sewing mechanism is of conventional construction and will not be described.
  • the chains 44 are driven in unison by an electric motor 46.
  • the sequence of operations commences with the expansion of jack 4 to move the suction cup 6 downwardly from its position shown in full lines until the suction cup engages the topmost sack near to the mouth end thereof.
  • the suction is then immediately effective to grip the sack and the jack 4 contracts to return the suction cup 6 to its full line position, bringing the mouth end of the sack with it.
  • the jack 7 now expands to swing the arm 2 about its pivot 3 into the position shown in dot and dash lines in FIG. 1; the sack is thus lifted, mouth upwards, and its mouth end passes into the guide shoe 10 to be positively located thereby with the body of the sack hanging downwardly.
  • the pack 26 has expanded to move the carriage 15 upstream to the said receiving station, i.e. to its FIG. 2 position.
  • the jack 22 now expands to close the gripper devices 17-18, which grip the topmost corners of the sack in the region of its gussetts.
  • the jack 13 now expands and suction in the suction cup 12 is thereby automatically applied.
  • the suction cup 12 moves inwardly and engages and grips the sack wall near to its mouth immediately opposite the suction cup 6.
  • the sack now being gripped at two opposite points by the suction cups 6 and 12, as well as by the gripper devices 17-18, the jacks 5 and 13 now contract and the jack 23 simultaneously expands so that the suction cups move away from one another to draw the sack mouth open and the gripper devices simultaneously swing inwardly towards one another to accommodate such opening movement.
  • the jack 20 contracts to lower the filling spout into the sack mouth, and as soon as the sack and the filling spout are properly engaged with one another the suction in the cups 6 and 12 is automatically interrupted so that the sack is released therefrom.
  • the jack 26 now contracts to move the carriage 15, carrying the empty sack, downstream to the sack filling station where the filling spout 16 on the carriage becomes aligned beneath the outlet 48 of a hopper containing the commodity with which the sack is to be filled. At the same time the sack comes to rest immediately above the posser platform 31.
  • Material is now fed from the hopper into the sack via the filling spout 16 and at the same time the jack 32 graduallyexpands so as to raise the vibrating posser platform as the sack is filled.
  • the sack is thereby possed and at the same time the weight of its increasing contents is supported by the posser rather than by the gripper devices 17-18.
  • the jack and 7 contract to return the sack lifting means to its rest position.
  • the jack expands to raise the filling spout out of the bag mouth to its position shown in dot and dash lines in FIG. 4.
  • the jack 23 now contracts to spread the gripper devices 17-18 apart so as to extend, and thereby close, the mouth of the sack.
  • the jack 42 now expands so as to close together the endless chains 34 and to grip the sack therebetween just below the intended sewing adjacent its top edge.
  • the chains themselves are stationary at this time; as soon as they have come together, however, the jack 22 contracts to separate the gripper members 17 and 18 and thus release the top corners of the sack which is now held upright by the grip of endless chains 34 and 35.
  • Drive is now transmitted to the chains and at the same time drive is transmitted to the endless conveyor constituting the posser platform 31 so that the sack is conveyed downstream by the action of chains 34 and 35 and the posser conveyor. Conveyance of the sack is shortly taken over by the chains 44 and the endless conveyor 33 and it is moved through the sewing mechanism where its mouth is sealed, and thence out of the apparatus.
  • the jack 26 expands to withdraw the carriage 15 to the sack receiving station, the jack 32 contracts to lower the posser 30, and the jack 42 contracts to spread the endless chains 34- and 35; thus the apparatus is made ready to receive the next sack to be filled.
  • FIGS. 6 and 7 of the drawings in the modification illustrated therein the single pair of suction cups of the apparatus described above is replaced by two suction devices each comprising three suction cups, the cups to 52 replacing the cup 6 of the lifting device .and the cups 53 to '55 replacing the cup 12.
  • the cup 51 is connected to the jack 5 on the swinging arm 2 in a similar manner to the cup 6, whilst the cup 54 is connected to the jack 13 in the same way as the cup 12.
  • Flexible metal plates 56 and 57 inter-connect the cups of each group of three and thus serve to support the outer pairs of cups 50, 52 and 53, 55, which outer cups are con- 4 nected into the main vacuum lines by means of flexible tubes '58.
  • a sack 8 has been picked up from the top of the stack by the three suction cups 50 to '52 and lifted through the guide shoe 10 into the mouth opening position, where its top corners have been gripped by the gripper members 17-18 and the three suction cups 53 to 55 have moved in under the control of the jack 13 to engage the sack; it will be noted that in this relative position of the two suction devices the six suction cups are disposed in three axially aligned pairs.
  • the jacks 5 and 13 now contracts so as positively to draw the two central suction cups 51 and 54 apart and, via the latter and the flexible metal plates 56 and 57, similarly to withdraw the outer pairs of cups.
  • the two opposite sides of the mouth of the sack are drawn apart in parallelism, as the gripper members 17-18 move inwardly, until a point is reached at which the opposite ends of the plates 56 and 57 engage with respective stops 59 mounted on the main frame of the apparatus so that the flexible plates are urged into the curved configurations shown in FIG. 7 as the jacks 5 and 13 continue to contract.
  • FIG. 7 shows the final positions reached by the suction devices when the mouth of the sack has been opened to its desired extent, and it will be observed that the mouth is now held in an oval configuration for the entry of the filling spout thereinto.
