Definitions

  • This invention relates to a method and apparatus for feeding empty flexible sacks or bags into an enclosure, for example into outer containers, or into the space between a plurality of vertical constraints (such as vertical settling boards, guide boards or vibrating plates or automatic packaging equipment) in circumstances where it is either impossible or inconvenient to introduce the empty, flexible sacks or bags into the space between the constraints from an open end or side of the machinery.
  • the invention relates in particular, to apparatus for feeding empty flexible sacks or bags into an outer container, for example an outer jute sack or bag, so as to produce a double package.
  • a method of feeding an empty flexible sack or bag into an enclosure comprises the steps of securing the open end of the sack or bag to a clamp or the like situated substantially directly above the enclosure, with the body of the sack or bag hanging outside the enclosure, supporting the body of the sack or bag at or near the top of the enclosure, and at least partially filling the sack or bag with the desired contents, whereby the weight of the contents causes the body of the sack or bag to slide over the top and into the enclosure.
  • the invention also provides apparatus for feeding empty flexible sacks or bags into an enclosure, comprising means situated substantially directly above the enclosure for clamping the open end of the sack or bag, with the body of the sack or bag hanging outside the enclosure, and means for filling the bag with the desired contents, one or more walls of the enclosure being formed or provided, at or near the top, with supporting and guiding means enabling the sack or bag to slide over the top and into the enclosure as filling proceeds.
  • said clamping means is movable from a first position substantially directly above the enclosure to a second position above and outside the enclosure, said clamping means being adapted to be moved to said second position for clamping the open end of the sack or bag and being adapted to be returned thereafter to said first position.
  • Said supporting and guiding means may comprise an outwardlly, preferably downwardly, extending lip formed or provided at or near the top of one wall of the enclosure.
  • the invention finds particular application in the lining of jute sacks with polythene liners during the filling operation.
  • the invention therefore provides apparatus comprising first means for clamping the open end of a first or outer sack (for example a jute sack), second means for clamping the open end of a second or inner sack (for example a polythene liner sack), said second means being movable from a first position substantially directly above said first clamping means to a second position above and to the side thereof, said first clamping means being formed or provided with an outwardly, preferably downwardly, extending guiding lip enabling said second sack to slide over the top of said first clamping means into the first sack when said second means is moved from its second to its first position.
  • a filling spout may be incorporated and movable with the second clamp, or a fixed filling spout may be provided substantially directly above said first clamping means.
  • FIG 1 illustrates the apparatus before filling of a double package is begun
  • FIG. 2 shows the inner sack of the double package just starting to fill
  • FIG. 3 shows the inner sack partially full
  • FIG. 4 shows the double package completely full.
  • a jute sack 1 is secured by its open end to a combined clamp and filling spout 2, hereinafter referred to as the jute-clamp.
  • a second combined clamp and filling spout 3 hereinafter referred to as the liner-clamp, which is pivotable from a position directly above the jute-clamp 2 (see FIG. 2) to a position above and to the side of it (see FIG. 1).
  • a polythene liner sack 4 is attached by its open end, in such a way as to allow air to escape, to the liner-clamp 3 which is then pivoted back to its centre-line position (FIG. 2).
  • the top of the jute-clamp 2, on that side to which the liner-clamp pivots, is formed or provided with an outwardly, preferably downwardly, extending plate or lip 5 which acts as a support and guide for the polythene liner sack 4 and enables it, when so required, to slide smoothly over the top of the jute clamp 2 into the jute sack 1.
  • the liner clamp 3 is pivoted to its outermost position (FIG. 1), and both the polythene liner sack 4 and the jute sack 1 are then applied to their respective clamps 3 and 2.
  • the liner-clamp 3 is then pivoted inwarly (FIG. 2), sliding the polythene liner sack 4 onto and partially over the plate or lip 5.
  • a pre-Weighed charge of material is released through the filling spout into the open mouth of the polythene liner sack 4, and the weight thereof drags the body of the sack 4 over the top of the jute-clamp 2 and into the open jute sack 1 (FIGS.
  • this pre-weighed material is discharged in two stages, the weight of the first stage being only sufficient to drag the liner into the jute sack without damaging it; the second stage of discharge takes place after the liner is correctly positioned inside the jute sack (FIG. 4). Correct relationship of the two combined clamps and filling spouts 2, 3, to one another, ensures that the full weight of the material is not taken by the thin polythene liner 4.
  • Both clamps are then released (the clamp 3 for the polythene liner 4 first), and the filled double package is allowed to fall sufficiently far to allow the polythene liner 4 to clear the jute-clamp 2.
  • Apparatus for feeding into a first sack and simultaneously filling an empty flexible second sack into said first sack comprising first means for clamping the open end of a first sack, second means for clamping the open end of a second sack, said second means being movable from a first position substantially directly above said first clamping means to a second position above and to the side thereof, filling means for filling the second sack with desired matter, and said first clamping means being provided with an outwardly extending guide enabling said second sack to slide over the top of said first clamping means into the first sack when said second means is moved from its second to its first position and when said second sack is filled from said filling means.
