Definitions

  • the present invention relates to a process and apparatus for handling stackable bulk bins.
  • the present invention is particularly suited for preparing bulk bins that are moveable between an erect operative orientation and a collapsed orientation i.e., collapsible, and assemblage between collapsed and erect orientations.
  • the bins also have a lid that can be opened and closed.
  • Bulk bins typically have a capacity in the range of 0.5 to 3 cubic metres and can be used for carrying a range of different materials including agricultural produce, mining materials and feedstock of manufacturing processes.
  • the high value of bulk bins means that it is desirable on economic grounds to recycle the bulk bins between loading points and unloading points.
  • One type of bulk bin that has gained wide acceptance is the knock-down bin which can be reused.
  • a feature of the knock-down bin is that while in an erect orientation, the bin can be filled and transport items from a supplier to a consumer, and once the bin has been emptied by the consumer, the bin can be collapsed and transported back to the supplier in a space saving manner. The supplier is then responsible for erecting the bin and subsequent refilling.
  • Knock-down bulk bins are generally of significant monetary value and may or may not include a bag liner that is discarded after each use, or on an as needs basis.
  • the present invention relates to a process for handling stackable bulk bins that may be used for items including, but by no means limited to, plastic bottle preforms and bottle closures, wherein the bulk bins have at least one lid that can be opened and closed , a bag liner having an entrance that is covered by the lid when closed, and the bulk bins are moveable ( i.e. collapsible and assemblage) between an erected orientation and a collapsed orientation, and wherein the process includes the steps of:
  • step a) erecting the bulk bins from the collapsed orientation to an erect orientation after each respective bin has been de-stacked from the stack of bulk bins according to step a);
  • steps a) to c) opening a lid of the bulk bins to allow items to be loaded into the bag liner, wherein steps a) to c) are carried out by automated machinery without personnel handling the bulk bins. It is within the scope of the present invention that steps a) to c) may be carried out consecutively, simultaneously, or disjunctively. For example, the steps may be carried out consecutively on the same bin, or simultaneously on multiple bins.
  • any one of more of steps a) to c) is carried out at any time on one bulk bin only i.e., different bins.
  • step a) may be carried out using automated de-stacking machinery that de-stacks one bulk bin at a time from a stack.
  • step b) may be carried out using automated erecting machinery that erects one bulk bin at a time
  • step c) may be carried out using automated lid opening machinery that opens the lids of one bulk bin at a time.
  • automated machinery or components thereof such as automated de-stacking station and automated erecting station refers to machinery that can carried out a functional task with respect to the bulk bins without the steps being carried out manually or without the need for intervention or handling of the bin by personnel.
  • the automated de-stacking station and the automated erecting station can de-stack a stack of the bulk bins and erect bulk bins respectively without continuous monitoring, supervision or handling of the bins by operator personnel.
  • the stack of bulk bins de-stacked in step a) are in a collapsed orientation.
  • step a) includes separating the bulk bins from the bottom of the stack, and suitably separating the bottom bulk bin by lifting the second bottom bin (and any of the bulk bins stacked thereon) from the bottom bulk bin.
  • the bulk bins include a base that is configured for receiving forktines of a forklift, a collapsible mechanism interconnecting the base and an upper assembly including the lid, and wherein step b) includes lifting the upper assembly by a lifting arm that engages the upper assembly and are driven upwardly and downwardly to operate the collapsible mechanism and, thereby move the bulk bins from the collapsed orientation to the erect orientation.
  • step b) includes engaging the base using a retaining device that retains the base on a surface, such as a conveyor, while lifting the upper assembly.
  • the retaining device may engage sides of the base.
  • the base may be configured with a sub-member and the retaining device passes over the sub- member which prevents the base from lifting upwardly.
  • the sub-member may be an upper deck of the base of the bin, or part the lower deck of the base of the bin.
  • the collapsible mechanism includes collapsible posts, each post having two or more members that move relative to each other.
  • the member may move telescopically relative to each other, or slidingly over one another.
  • the collapsible mechanism of the bulk bins includes linkage members that are pivotally interconnected and collapse inwardly relative to an operative position of the linkage members when the bulk bins are in an erect orientation and, step b) includes driving the linkage members toward the operative position by lifting the upper assembly to an extended position beyond the operative position, and thereafter lower the upper assembly so that the linkage members are positioned into an operative erect orientation.
  • the bulk bins includes four pairs of linkage members, and the process includes driving each pair of linkage members toward, and into, the operative position by laterally moving members of the automated erecting station that move laterally to the direction of the movement of the linkage members. The process also includes preventing the linkage members from moving inwardly into a collapsing direction by the lateral moving member that can move laterally to the lifting arm.
  • the collapsible mechanism includes a releasable lock for retaining the bulk bins in an erected orientation.
  • the linkage members of the collapsible mechanism can be extended beyond their effective operative length and the releasable lock includes cooperating pairs of connector formations
  • step b) includes lifting the upper assembly so as to space the co-operating pairs of connector formations one above the other when the collapsible mechanism is in the extended position and, thereafter lowering the upper assembly to the erected orientation in which the connector formations engage.
  • the pairs of connector formations include co-operating male and female formations such as pins received within an opening or slot.
  • the bulk bin may have bag liner that is supported or attached to either one or a combination of: i) the upper assembly, ii) the collapsible mechanism, or iii) the base of the bin.
  • a suitably bulk bin is described in the Australian provisional applications 2010903949 and 201 1900160, the contents of which are hereby incorporated by express reference.
  • the bulk bag is suitably attached to the upper assembly, and remains attached to the upper assembly while the bin is moved from an erect orientation to a collapsed orientation, and vice versa.
  • the bulk bins include two lids having oppositely disposed hinges and step c) includes pivoting the lids in opposite directions from a closed position to an open position.

  • the process also includes disassembling (de-erecting) the bulk bins (step 9).
  • the disassembling step may essentially be a reverse of the erecting step described above.
  • the disassembly step may comprise, initially holding the base of the bulk bin and lifting the upper assembly of the bin so as to disengage the locking formations that hold the corner posts in a locked position. The posts can then be folded inwardly in to the position shown in Figures 3 and 4.

  • the stack When the stack has reached the necessary height (or number of bins), the stack can be conveyed out of the stacker by the conveyor.
  • the present invention requires the steps 2, 3 and 4 of the process be carried out using automated machinery without the need for direct personnel handling the bulk bins.
