Definitions

  • unitised loads of bagged product on pallets as well as pallet-less unitised loads of bagged product to lift and handle a plurality of filled bags at once is well known. It is commonly known that unitised loads of bagged product on pallets can be uncovered or covered for protection against rain and other environmental conditions.
  • To unitise a plurality of filled bags into a pallet-less multi-layer load typically comprises a bottom layer of reduced dimensions defining lateral spaces for gripping purposes. It is presently known to form pallet- less multi-layer loads from a plurality of filled bags stacked one layer onto the other so as to form a substantially parallel sided load assembly.
  • These filled bags which are not only, but typically bags filled with cement are grouped in superposed layers, each layer having a square or rectangular horizontal form.
  • a layer of reduced width is provided at the lower part of the load, during stacking, said "reduced layer” being constituted by fewer filled bags and defined by a smaller square or rectangular geometrical surface than the peripheral surface of the normal layers on top of that. Consequently, the reduced layer defines, with the normal layer under which it is formed, two lateral empty spaces parallel to each other and each in the form of a notch representing a right-angled dihedron.
  • the vertical side of each dihedron opening is constituted by a lateral face of the reduced layer, whilst the horizontal side of each dihedron opening is formed by the portion of horizontal surface of the adjacent normal layer above the reduced layer.
  • the lateral spaces thus defined by the reduced layer are used to enable the load to be lifted and handled by a fork lift truck or by slings.
  • This invention relates to a method of forming a transportable stack of bagged substance that is transportable in response to a lifting action involving laterally spaced lifting elements and to a bagged substance supporter for use in supporting a stack of such bagged substance. While not so limited the invention finds particular use in the non-pallet type transportation of stacked bagged substance by way of a forklift or slings. (4) PRIOR ART DESCRIPTION
  • Figure 1 shows one embodiment of a bagged substance stack supporter in the form of a slip limiting means incorporating sheet in three dimensional view
  • Figure 2 shows a variety of embodiments of the bagged substance stack supporter in the form of spaced lifting element accommodating and slip limiting means carrying sheets in side elevation
  • Figure 3 shows the bagged substance stack supporter of the figure 1 embodiment as underlying a multi layered stack of pre-filled bags at the ready to be engaged by laterally spaced lifting elements in side elevation
  • Figure 4 shows the bagged substance stack supporter in the form of a plain sheet of a size extending beyond the underside of a stack and enveloping stack layers along its lower reaches at the ready to be engaged by laterally spaced lifting elements, in side elevation,
  • Figure 5 shows the bagged substance stack supporter in its various figure 2 embodiments as underlying a multi layered stack of pre-filled bags at the ready to be engaged by laterally spaced lifting elements in side elevation
  • Figure 6 shows the bagged substance stack supporter of one of the figure 2 embodiments in its appropriate figure 5 stack underlying condition as engaged by laterally spaced lifting elements in the form of the engaging arms of a forklift rendering the stack at the ready to be lifted, in side elevation,
  • Figure 7 shows the bagged substance stack supporter of one of the figure 2 embodiments in it appropriate figure 5 stack underlying condition as engaged by laterally spaced lifting elements in the form of slings, in side elevation
  • Figure 8 shows the bagged substance stack supporter in the form of a stack lower reaches enveloping sheet corresponding to figure 4 as engaged by laterally spaced lifting elements in the form of the engaging arms of a forklift, in side elevation
  • a bagged substance stack supporter in the form of an at least one of spaced lifting element accommodating and slip limiting means associated bagged substance supporting sheet is generally indicated by reference numeral 10.
  • the stack supporter 10 comprises a supporter body in the form of a bagged substance supporting sheet 2 that is of flexible though non-stretchable material and of adequate strength to support a stack as constituted from a plurality of layers of bagged substance as overlappingly stacked in forming a unitised load, and at least one of spaced lifting element accommodating and slip limiting means as extending in appropriately spaced parallel relationship along the sheet 12, as discussed in detail below, in being snugly receivable along stack bottom region formed dihedral notches, also as discussed in detail below.
  • the latter in the form of parallel strips of non-slip type substance 14 that is either integrally formed with the sheet 12 or applied thereto and extending along opposite end regions 16 of the sheet 12. While not shown, at least part of the surface of the sheet 12 facing away from the strips 14 can carry a layer of adhesive substance to promote the securing of the stack supporter 10 to the bottom of a stack of in the process of forming a multi layered transportable stack of bagged substance. Typically the areas mirroring the strips 14 can thus carry adhesive.
  • Operative positioning of the sheet 12 to a multi layered stack of bagged items depends on its way of formation. Positioning can be done prior to engaging such stack with lifting means by for example, while still in an upside down positioning, positioning the sheet 12 along the notch presenting ends of the stack where after the stack, as thus holding the supporter 10, becomes inverted. The stack can even be constructed above the supporter 10 in the process positioning it above the lowermost layer as thus forming the relevant notches. When the sheet is formed with a layer of adhesive substance the operative positioning will involve its adhesive securing to the stack.
  • the multi layered stack of pre-filled bags can even be pre-strapped along its notches and opposite side regions for improved stack stability or straps or the like can be used to hold the supporter 10 in position prior to lateral lifting element engagement.
  • Such straps can naturally fulfill both functions. In whichever way formed the supporter 10 will at the latest on lifting elements commencing with the lifting of the stack as thus supported be at the ready to perform its supporting function.
  • the latter is in the form of stack extending notch snugly complementing spaced lifting element accommodating members 18 being able to take on a variety of forms.
  • at least part the surface of the sheet 12 facing away from the elements 18 can again carry a layer of adhesive substance to promote the securing of the stack supporter 10 to the bottom of a stack in the process of forming a multi layered stack of pre-filled bags, as becoming adhered to the stack as already discussed. But again, the use of such layer of adhesive substance is not imperative often depending on the way a stack is constructed.
  • the members 18 are in on embodiment the form of angle incorporating L-shaped formations 20 that are secured in parallel to one another along the opposite edge regions 16 of the sheet 12.
  • the formations 20 are suitably spaced apart to be snugly receivable along stack bottom region formed notches 22 as shown in figure 2(b).
  • the lifting element receiving faces 24 of the formations 20 are arranged against slippage of the lifting means thereto by being fitted with rubberised strips 26 as thus also incorporating the slippage limiting means.
  • the L shaped formations 20 can incorporate taperedly formed slippage limiting strip incorporating inner sections 28 of which the apexes 30 face away from one another. This promotes the pre-tightening of the stack supporter 10 once a stack as thus underlain by the supporter 10 of this embodiment is exposed to a lifting action.
  • the shape of the supporter 10 once fitting a stack is shown in figure 2(d).
  • the formations 20 can further be generally Z-shaped in also having lengths 32 extending some distance below the core supporting part of the stack once performing a stack supporting function, as shown in figure 2(f).
  • the free ends 34 of the formation can conveniently be in the form of eyes to limit the possibility of sheet puncturing.
  • the members 18 can even be of rectangular or square end profile forming enclosed lifting element channels of engagement. This is typically an arrangement where no layer of adhesive substance is required.
  • FIG. 1 While a variety of spaced lifting element accommodating member configurations are discussed in figures 1 and 2 it will be appreciated that it is not so limited.
  • the norm is its serving the objective of accommodating spaced lifting elements and preferably also limiting slip between a lifting element and the sheet 12 that may cause collapse of a multi layered transportable stack of bagged substance as supported by the stack supporter 10.
  • the objective of the supporter 10 is thus to underlie a multi layered transportable stack of bagged substance 36 in preventing its collapse on being transported in response to a lifting action by way of laterally spaced lifting elements such as the arms of a forklift or slings.
  • the bagged substance such as bagged cement 38 is conventionally overlappingly stacked while two opposing bottom edges 40 are formed defining the laterally extending notches 22. This is brought about by forming a bottom layer 44 along the stack 36 of reduced lateral dimensions.
  • a transportable multi layered stack of bagged substance is formed once the stack 36 is underlain by the supporter 10.
  • the step in getting the stack 36 to become so underlain can be achieved in a variety of ways. In whichever way formed the stack 36 must at any rate be properly underlain just prior to the performance of a stack lifting action. As shown in figure 3 the stack 36 is thus underlain by the supporter 10 of the figure 2(a)/2(b) configuration once its end regions 46 are located within the notches 22 while the spaced lifting element accommodating members 18 (of this
  • the layer of adhesive material can be dispensed with as the geometry of the members 8 already accommodates their maintenance within the notches 22.
  • Figure 5 shows the readying of the multi layered transportable stack of bagged substance 36 in being underlain by the supporter 12 as involving a variety of spaced lifting element
  • Figure 5(a) and 5(b) thus correspond with the spaced lifting element accommodating members 8 of figures 2(a) and 2(b), figures 5(c) and 5(d) with the members 18 of figures 2(c) and 2(d), figures 5(e) and 5(f) with the members 18 of figures 2(e) and 2(f) and figures 5(g) and 5(h) with the members 18 of figures 2(g) and 2(h).
  • the stack underlying action by means of the supporter 10 can also involve the wrapping of the sheet 12 about a number of bottom layers 50 along the multi layered stack of bagged substance 36.
  • the sheet 12 is naturally of appropriate size while its opposite end regions 52 are sandwiched between two layers 54 of bagged substance in the process enveloping the relevant bottom layers 50.
  • the sheet 12 is pinched up against the upper faces 48 of the notches 22 and the lifting means held against release via the strips of non-slip type substance 14 or the members 18, whichever the case, while in the case of enveloping the relevant bottom layers 50 the supporting action of the stack support is supplemented by a stack foundation forming effect. Owing to the strength of the sheet 12 and the pinching effect within the notches 22 the stack 36 as thus underlain is firmly held against any collapse for safe transportation.

Abstract

Un support de pile de substance ensachée 10 comprend un corps de support sous forme de feuille de support de substance ensachée 12 et des éléments logeant des éléments de levage espacés 18 sous forme de formations en L 20 qui sont fixées en parallèle les unes par rapport aux autres le long des régions de bord opposé 16 de la feuille 12. Les formations 20 sont espacées de manière appropriée pour permettre une réception ajustée le long des encoches formées dans la région inférieure de la pile 22. Lors de l'utilisation, le support 10 est sous-jacent à une pile 38 alors que les formations 20, logées à l'intérieur des encoches 22 sont pincées contre celles-ci une fois que la pile ainsi située en dessous est soulevée par une fourche par exemple. Comme la feuille 12 a une résistance adéquate, le support 10 est utilisé pour le transport d'une pile multicouche de substance ensachée.
