Definitions

  • the present invention relates to a palletising system for use in the transport and handling of articles or groups of articles.
  • the end user must unload the load and its associated pallet from the road trailer or other transport means by which the load is supplied to the end user. Having unloaded the palletised load, the end user must then unpack the load from the pallet. Often, the end user has a large number of such palletised loads in his premises and each load results in an empty pallet which must be removed from the storage area so as not to act as an obstacle to free passage of workmen and machines in the storage area.
  • the end user must then return the empty pallet to the manufacturer or face a charge for the loss of that pallet.
  • the pallet is handled many times for each delivery of a load to the end user and return to the supplier. This causes wear and tear to the pallet as well as adding cost for the end user.
  • an end user can unload only the load and not the associated pallet from the flat bed of the road truck or other transport means bringing the load onto his premises. The end user thus does not remove the pallet from the truck, so that the pallet can be returned directly to the supplier without having to be handled on the end user's premises.
  • the end user can unload both the pallet and its associated load for storage on site by engaging the tines of the fork lift truck with those channels having a closed top. When the user requires to unpack the load, it can readily be lifted off the pallet and unpacked separately. The unloaded pallet can then be handled by a fork lift truck by inserting the tines of the fork lift truck into the passages which have closed tops.
  • the invention thus enables an end user to avoid the need to handle and store empty pallets on site and minimises handling of such pallets as may remain on site.
  • the close top channels have open bottoms. This permits access of fork lift tines from below as well as from one side, and reduces the weight of the pallet.
  • the pallet of the invention comprises a generally planar load bearing surface which is adapted to receive the load to be carried by the pallet.
  • the surface is preferably substantially flat and will typically have a square or rectangular plan shape to mimic the load bearing top surface of a conventional pallet.
  • the surface may be a continuous surface, except for the locations at which the open topped channels are positioned.
  • the load bearing surface is provided by a sheet of material which is corrugated to form a series of parallel open topped channels with intermediate channels which have an open base but a closed top.
  • such corrugations have a squared or tapered cross section to aid accurate location of the tine of the fork lift truck in the corrugations and to minimise excessive lateral movement of the tine within the channel.
  • the cross sectional size and shape of the corrugations and the location of the corrugations across the plan area of the load bearing surface can be selected according to the type of load to be carried and the spacing between the tines of the fork lift truck.
  • the load bearing surface may have a plurality of parallel corrugations at 10 to 15 cm spacing.
  • the load bearing surface may be provided with underlying support or bracing structures, for example transverse blocks or vertical webs between the side walls of adjacent open topped channels to enhance the strength and rigidity of the pallet.
  • underlying support or bracing structures for example transverse blocks or vertical webs between the side walls of adjacent open topped channels to enhance the strength and rigidity of the pallet.
  • a satisfactory pallet can be made from a simple corrugated sheet metal or plastic, notably one incorporating glass fibre or metal rod or other re-inforcement, since the tines of the fork lift truck or other lifting mechanism extend through the structure of the pallet and provide a measure of rigidity and support to the pallet.
  • the exact form and thickness of the sheet from which such a pallet is made will depend upon the load which the pallet is to carry. Typically, such a load will be at least 100 kg, usually 500 to 2000 kg, and the sheet can readily be selected from commercially available materials as is known in the industry having regard to the safety and other requirements for pallets to carry such a load.
  • load bearing is therefore used herein in respect of the pallet of the invention to denote that it can support a load of at least 100 kg, preferably at least 2000 kg.
  • the invention will be described hereinafter in terms of a preferred embodiment of the pallet which is a corrugated sheet to provide alternating closed top and open top channels.
  • Such a pallet can be readily made by rolling or otherwise corrugating a sheet metal of suitable thickness using conventional techniques and equipment.
  • a particularly preferred material for use in the manufacture of the pallet of the invention is a plastic or zinc coated corrugated sheet, for example of the type used to provide metal cladding sheets for buildings; or a moulded polyalkylene polymer sheet, notably a polyethylene or polypropylene sheet. Recycled plastics materials may be used form the pallet.
  • the invention has been described above in terms of a load bearing surface having open topped channels. However, it may be desired to provide such channels with hinged top members which pivot about their longitudinal edges to provide a closed top to the channel, but pivot upwardly to allow a tine located in the underlying channel to pivot the top members aside as the tine rises out of the channel.
  • the top member may be formed as two opposed half tops, each pivoted to an opposed edge of the lip of the channel to reduce the height of the flap which is formed as the top members are pivoted upwardly by the rising tine.
  • Such top members may be desirable where the pallet is to carry a fluent material contained within a flexible walled bag as opposed to a rigid container or series of rigid articles in a box or shrunk wrapped to form a unitary load.
  • the invention has also be described above in terms of a pallet into the passages of which the tines of a fork lift truck are inserted from one direction.
  • the invention may also be applied to a pallet where the tines can enter passages from all four directions. This is achieved by forming the pallet with two series of passages at right angles to one another so that the tines can enter passages either from either front or back or from either side.
  • Such passages can be formed at different levels in the pallet, for example by securing two corrugated sheets to each other with the line of the corrugations in one sheet at right angles to the line of corrugations in the other sheet.
  • both lines of corrugations can be formed in the same sheet of material to give a structure which comprises a sheet member having a series of upraised dimples extending normally to either side of the plane of the sheet, the dimples being laid out on a grid pattern similar to an egg crate design.
  • the dimples can be provided by metal or other blocks attached at the desired locations on both sides of a metal sheet, but are preferably formed by a suitable vacuum or other moulding technique in a sheet of plastic material. This structure allows the interlocking of pallets for stacking.
  • the movable tine or tines of the fork lift permit adjustment of the effective number of tines. For example, two tines can become one, or three tines can become one. This means that the fork lift truck can pick up pick up pallets of different sizes. In a preferred embodiment, adjacent tines may be interlocked together to form a single lifting structure.
  • the tines may be moved laterally by any suitable means, for example by means of hydraulics.
  • the tines of the fork lift may be provided as an attachment which is mounted on a suitable vehicle. Accordingly, another aspect of the invention provides an attachment for the rise and fall mechanism of a fork lift truck or the front end loader of a tractor as specified in claim 8.
  • the pallet shown in Figure 1 comprises a sheet member 1 which has been formed into corrugations 2, some of which have an open top 3, and intermediate ones which have a closed top but an open bottom face 4.
  • a sheet is made by casting a polyethylene resin about metal rod or glass fibre reinforcement.
  • the plan dimensions of the pallet are typically 0.5 to 1.5 metres wide and 1 to 2 metres front to back.
  • the pallet is typically from 5 to 10 cm deep vertically and the corrugations are typically from 4 to 9 cm deep and from 5 to 10 cm wide.
  • a load 5 is placed upon the top face of the pallet.
  • a pair of tines 10 of a fork lift truck are inserted into a pair of the closed top channels 4. When the tines are raised, they engage the closed top of the channel and lift the pallet and load with them. If the tines are placed in a pair of open topped channels 3 (as shown by 10') raising the tines brings them into direct contact with the base of the load 5 so as to lift the load without lifting the pallet.
  • the fork lift mechanism can have more than two tines, for example as many as seven or eight, so as to increase and spread the effective load bearing and stiffening surface of the tines. The user can thus handle the load and pallet together or can separate the load from the pallet.
  • the unloaded pallet can thus remain upon the flat bed of the road or rail truck in which it is supplied to the end user for return to the supplier without the need for the end user to handle the pallet. The wear and tear damage to the pallet during handling is thus minimised.
  • the pallet shown in Figures 2-4 comprises a sheet of reinforced plastic or metal 20 having a plurality of dimples 21, 22 formed therein on a grid pattern.
  • the dimples 21 extend above the plane of the sheet, and the dimples 22 extend below the plane of the sheet in the manner of an egg box.
  • the dimples provide crossing channels 3, 4 on each side of the sheet so that the tines of the fork lift truck can enter from any one of the four sides of the pallet.
  • the dimples on the underside of the sheet form channels with closed tops, those on the upper face of the sheet forming open topped channels. When a tine is inserted into the channel between dimples on the lower face of the sheet, it will raise both the sheet and any load carried on the upper ends of the dimples on the top face of the sheet.
  • tops of the upper dimples 21 form a generally planar load carrying surface which in this example has a greater area than the bottoms of the lower dimples 22.
  • the pallet has between three and ten channels, preferably in each direction.
  • FIG. 5 shows an attachment for the front end loader of a tractor or for fitting to the rise and fall mechanism of a fork lift truck.
  • This attachment comprises a support frame 30 which has mounting hooks 31 for mounting the attachment on a fork lift carriage.
  • the support frame 30 carries a series of laterally spaced apart projecting tines 10, the number and spacing of which can be selected to suit the spacing of the channels 3 and 4 in the pallet. Eight tines are illustrated, but the number is preferably between four and eight.
  • the two outermost tines 10 are mounted slidably to the frame 30 and can be moved laterally towards or away from their neighbouring tines by hydraulic rams. Each outermost tine can be brought up into contact with its neighbour so that they interlock to form a single load bearing member which can fit into a single channel 3, 4.
  • the effective number of tines can therefore be adjusted between 6, 7 and 8 depending on the number of channels in the pallet to be engaged.
  • Other tines could also be laterally movable to allow the attachment to accommodate different channel spacings and to square up the machine or a pallet mounted on the tines 10. Examples of tines which are engaged with each other are shown in Figure 8.
  • Figure 8a illustrates generally circular section tines 10a, 10b interlocking
  • Figures 8b and 8c illustrate interlocking of, respectively, three tines 10c, 10d, 10e and two tines 10f and 10g to form effectively single larger tines.
  • the frame 30 can carry a pusher mechanism 33 which is actuated by an hydraulic ram 32 or the like to engage with the load 5 on the pallet so that it can be pushed off the tines 10 when it has been raised off the pallet and onto a suitable storage or work surface, as illustrated in Figures 6 and 7.
  • the pusher mechanism 33 may be connected to the frame 30 by a straight linkage or a pivoted linkage 35, via a pivot point 40.
  • Figure 7 also shows an optional pallet engaging member 34 which can be used to grab an empty pallet and pull it onto the tines 10 of the fork lift.
  • the pallet engaging member 34 is a hook which held in place in a dimple 22 in the pallet by a releasable latch mechanism, for example hydraulic, mechanical or electronic.
  • the latch mechanism is provided by a spring and hydraulically activated pin.
