Definitions

  • the invention relates to an apparatus and method for discharging of flour from a liner bag in a cargo container.
  • Liner bags are large flexible bags for lining the insides of cargo containers and containing liquid or powdered goods such as flour during transportation. At the destination, the liquid or powdered goods are then discharged from the liner bags into conveying pipelines or other transport systems and transported into the relevant storage bins/silos.
  • conventional methods of discharging powdered goods such as applying a tilt to the container to discharge the powdered goods by gravitational force does not work well with some type of flours. For example, the discharge of wheat flour using such a method may take up to 5 hours.
  • the present invention is an apparatus and method for discharging flour from liner bags in cargo containers as defined in the claims.
  • Figures 1a and 1b are perspective views of an apparatus for the discharge of flour from liner bags in cargo containers.
  • Figures 2a and 2b are perspective views of another apparatus for the discharge of flour from liner bags in cargo containers.
  • Figures 3a and 3b are perspective views of a further apparatus for the discharge of flour from liner bags in cargo containers.
  • Figure 3c is a sectional view of the apparatus for the discharge of flour from liner bags in cargo containers.
  • numeral 100 generally designates an apparatus for the discharge of flour from liner bags in cargo containers.
  • Apparatus 100 includes a sheath body 10 with an inlet 15 and outlet portions 19, formed of rigid or semi-rigid materials such as stainless steel or aluminium sheets.
  • the sheath body may be formed of other materials as long as the material is sufficiently rigid to allow the transmission of agitation action and energy such as vibration without loss.
  • the sheath body 10 is formed in the shape of a funnel with a wider inlet portion 15 of rectangular or generally rectangular shape which tapers down to a narrower outlet portion 19 of circular cross-section.
  • the rectangular shape of the funnel becomes generally octagonal defined by the edges 11a, 11b, 11c, 11d, (other edges not shown).
  • the surfaces between the edges 11 may be flat or somewhat rounded.
  • the shape of the outer surface of the sheath body 10 transforms to being of circular or generally circular cross- section.
  • other shapes of the sheath body 10 may be used as long as the sheath body 10 is able to receive and fit over a discharge outlet 16 of a liner bag 18 in a cargo container body 20 and the sheath body 10 is in contact with the discharge outlet 16 such that agitation action from the sheath body 10 may be provided to the discharge outlet 16.
  • the discharge outlet 16 of the liner bag 18 may also be fitted over the inlet portion 15 of the sheath body 10 as long as there is sufficient contact between the discharge outlet 16 and the sheath body 10 such that agitation action from the sheath body 10 may be provided to the discharge outlet 16.
  • Apparatus 100 also includes an agitator 12 for providing an agitation action to the sheath body 10.
  • the agitator 12 is a vibration motor mounted on the surface of the sheath body 10. When the vibration motor 12 is switched on, a vibrating action is provided from the vibration motor 12 to the sheath body 10 and the discharge outlet 16.

  • Retaining elements 14 such as steel cables or straps are further provided and attached to the sheath body 10 to hold the sheath body 10 in position over the cargo container opening, specifically over the discharge outlet 16.
  • Other known or obvious forms of retaining elements 14 may also be used to secure the sheath body 10 to ensure that the sheath body 10 remains in position over and in contact with the discharge outlet 16 during the operation of the apparatus 100.
  • the discharge outlet 16 of the liner bag 18 is inserted into the inlet portion 15 of the sheath body 10 and pulled through, perhaps as far as the outlet portion 19 of the sheath body 10 and folded over the outlet portion of the sheath body 10 but operation may still ensue as long as the discharge outlet 16 is received in the inlet 15 of the sheath body 10.
  • a flexible pipe 22 is then connected over the outlet portion 19 of the sheath body 10 on one end of the flexible pipe 22 and to a conveying pipeline/system (not shown) on the other end of the flexible pipeline 22.
  • an agitator 12 such as the vibration motor in the present apparatus is activated, agitation action in the form of vibration energy is transmitted from the agitator 12 to the sheath body 10 and the discharge outlet by contact.
  • the vibration energy assists to facilitate the flow of the flour in the discharge outlet into the flexible pipeline 22 for further processing or storage.
  • the agitator 12 need not be mounted directly on the sheath body 10, as long as the agitation action is transmitted to the sheath body 10.
  • numeral 200 generally designates another apparatus for aiding the discharge of flour from liner bags in cargo containers.
  • Apparatus 200 includes a support frame 30 for mounting over the opening of a cargo container (not shown).
  • frame securing elements 32 such as releasable clamps for mounting the support frame 30 over the opening of a cargo container (not shown).
  • Apparatus 200 further includes a sheath body 10 generally as described above with respect to figures 1a and 1b secured to the support frame 30 at a position where the sheath body 10 will be able to receive and fit over a discharge outlet (not shown) of a liner bag (not shown) in the cargo container (not shown) over which the support frame 30 is to be mounted.
  • Apparatus 200 further includes an agitator 12 for providing an agitation action to the sheath body 10.
  • the agitator 12 is a vibration motor mounted on the surface of the sheath body 10 although direct mounting on the sheath body is not required, as discussed above; for instance, the agitator 12 could be mounted on support frame 30 and the agitating action of the agitator 12 is transmitted to the sheath body 10 through the support frame 30, although this is not the most efficient technique.
  • the support frame 30 ensures that the sheath body is held securely in position over and in sufficient contact with the discharge outlet (not shown) of the liner bag (not shown) such that an agitation action from the sheath body 10 may be transmitted to the discharge outlet (not shown) of the liner bag (not shown).
  • Support frame 30 also provides support to the liner bags (not shown) and holds it in place in the cargo container (not shown) when the cargo container (not shown) is tilted at an angle during the discharging process.
  • the sheath bodylO may optionally be provided with retaining elements (not shown) such as steel cables or straps to further secure the sheath body 10 to the support frame 30 or the cargo container body (not shown).
  • a resilient element 34 is provided to prevent the agitation action from the agitator 12 from being absorbed and dissipated by the body of the support frame 30 .
  • One or more resilient elements 34 such as compression springs, compressible rubber or other devices such as hydraulic or pneumatic pistons may be provided on the support frame 30 for mounting the sheath body 10 onto the support frame 30. The compressive action of the compression springs, compressible rubber or the compressible fluid medium of the hydraulic or pneumatic pistons allow the sheath body 10 to vibrate without the vibration energy of the sheath body from being absorbed and dampened by the body of the support
  • the support frame 30 is first mounted over the opening of a cargo container (not shown) via releasable clamps 32.
  • the discharge outlet (not shown) of a liner bag (not shown) is inserted into the inlet portion 15 of the sheath body 10 and pulled through the outlet portion 19 of the sheath body 10 and folded over the outlet portion of the sheath body 10 although as noted above with regard to figures 1a and 1b, the apparatus may still function without pulling the discharge outlet (not shown) through the outlet portion 19 of the sheath body 10.
  • a flexible pipe 22 is then connected over the outlet portion 19 of the sheath body 10 on one end of the flexible pipe 22 and to a conveying pipeline/system (not shown) on the other end of the flexible pipeline 22.
  • an agitator 12 such as the vibration motor in the present apparatus
  • agitation action in the form of vibration energy is transmitted from the agitator 12 to the sheath body 10 and the discharge outlet by contact.
