DETAILED DESCRIPTION OF pREFERED MDQDIUZNTS Figure 1 shows a typical use of layer pads interleaved between layers 13 of, in this example, beverage containers 11 loaded onto a pallet 12. Layer pads intended for re-use are typically formed of a generally square sheet of fairly rigid material such as for example polypropylene, adapted to fit within the surface area of a standard pallet such as commonly used in the food and beverage industry.
The layer pad may be solid or may be formed of a top and bottom sheet with an intermediate honeycomb or corrugated internal structure for example.
With reference to figure 2 a layer pad cleaning system according to a preferred embodiment of the invention includes a horizontally disposed conveyor system 21 adapted to support and convey a plurality of layer pads 22 through a number of operational zones 23, 24 and Layer pads 22 may be loaded onto conveyor system 21 manually but in at least one preferred embodiment are picked from a stack of layer pads 26 by a loading pick and place mechanism 27, raised vertically, translated over, and placed onto a first end 28 of conveyor system 21 as indicated by the sequence of arrows.
COMS 10 No: SMBI-00495966 Received by IP Australia: Time 21:30 Date 2003-11-14 14Nov, 2003 20:22 Wallington-Dummer Sydney N o- 33 66 P 12 8 Similarly, layer pads 22 after travelling the length of conveyor system 21 may be removed from it manually or allowed to drop to a stack, but in at least one preferred embodiment as shown In figure 2, layer pads 22 are automatically picked and lifted when reaching the second end 29 of conveyor system 21 by an unloading pick and placed mechanism 30, translated clear of the second end 29 of conveyor system 21 and placed on cleaned layer pad stack 31. Layer pads 22 thus are carried by chain or roller conveyor system 21 from first end 28 to second end 29 as indicated by the arrows placed along the upper strand 34 of the conveyor system as depicted in figure 2.
Both loading and unloading pick and place mechanisms 27 and 30 are preferably comprised of suitable guide means and actuators with pick-up heads 32 provided with an array of vacuum cups 33 adapted to adhere to the surface of a layer pad when brought into contact with the surface and applied with vacuum pressure.
A stack of layer pads on a pallet may thus be brought to first end 28 of conveyor system 21 by a fork lift truck (not shown) for example, and similarly removed by a fork lift truck, when a sufficient number of cleaned layer pads have been placed in a stack, also on a pallet.
Preferably, in at least one preferred embodiment, conveyor system 21 is a chain conveyor system includi.ng at least two spaced apart parallel chains 34 driven by an COMS ID No: SMBI-00495966 Received by IP Australia: Time 21:30 Date 2003-11-14 14.Nov. 2003 20:22 Wallinston-Dummer Sydney No.3366 P. 13 S9 electric motor (not shown). Chains 34 are provided with upwardly projecting dogs 35 spaced at intervals along the length of each chain adapted to push against the trailing edges of layer pads. Projecting dogs 35 are spaced so as to allow for a single layer pad to be positioned on the chains between successive dogs In an alternative preferred embodiment conveyor system 21 is in the form of a roller conveyor utilizing multiple spaced apart rollers. Rollers are preferably coated with a high friction material to ensure reliable drive of layer pads along the conveyor. As further assurance of positive drive through the operational zones, suitably spaced upper rollers may be used so as to drive pads between vertically opposed rollers.
Conveyor system 21 maybe urged into continuous motion by the electric drive motor or may be incremented by the motor so as to leave layer pads on the conveyor system stationary within each operational zone for a predetermined period.
The operational zones 23, 24 and 25 will now be described in more detail with reference to figures 3, 4 and With reference to figure 3, single layer pads 22 are conveyed to enter first operational zone 23. In this first zone liquid detergent 36 is applied to the upper and lower surfaces 37 and 38 respectively of the layer pad 22 through upper and lower arrays 39 and 40 of spray nozzles 41. In COMS ID No: SMBI-00495966 Received by IP Australia: Time 21:30 Date 2003-11-14 14.Nov. 2003 20:23 Wallington-Dummer Sydney N o. 33 66 P 14 10 the preferred embodiment of figure 3, the conveyor system moves layer pad 22 continuously through operational zone 23. Following the spraying stage the layer pad currently passing through this first operational zone passes between at least one pair of brushing rollers 42 and 43 disposed transversely above and below the path of the layer pad and extending across the width of the conveyor system so as to cover the full width of the layer pad.
As the layer pad leaves the first operational zone 23 it passes between a pair of air knives 44 and 45 disposed, like the brushing rollers, above and below the path of the layer pad and extending across the width of the conveyor system so as to cover the full width of the layer pad. The air knives supply air under pressure through a narrow slit opening directed at the surfaces of the layer pad to remove the bulk of the liquid detergent from the upper and lower surfaces of the pad. In at least one preferred embodiment the air knives are replaced or augmented by top and bottom surface wipers disposed across the width of the conveyor to wipe the bulk of moisture from the pad surfaces.
The layer pad now enters the second operational zone 24 as shown in figure 4. The layout of operational 24 is similar to that of operational zone 23, differing only in that there are no brushing rollers as shown in figure 4. In this zone, both upper and lower surfaces of the layer pad are rinsed with sanitized water applied through similar COMS ID No: SMBI-00495966 Received by IP Australia: Time 21:30 Date 2003-11-14 14Nov. 2003 20:23 Wallington-Dummer Sydney N o. 33 66 P 11 upper and lower arrays of spray nozzles. In a least one preferred embodiment of the invention, the water used is sanitized by an ultraviolet sterilization system or by a peroxyacid/organic acid sanitizing agent. At the exit of this second operational zone also, the layer pad passes between at least one pair of air knives and/or wipers which remove the bulk of the sanitized water from the upper and lower surfaces of the pad.
The layer pad now enters the third operational zone 25.. The layout of operational zone 25 is similar to that of operational zone 24 as shown in figure 5. In this zone both upper and lower surfaces of the layer pad are sprayed with a sanitizing anti-bacterial spray such as peroxyacid/organic acid agent applied through similar upper and lower arrays of spray nozzles. On leaving this third zone the layer pad passes between at least one pair of air knives which ensure that the pad arrives at the unload end of the conveyor system in a completely dry state.
In at least one preferred form of the invention layer pads may leave the third operational zone to enter a fourth operational zone adapted to further drying of the pads.
complete drying may be achieved by any one of, or a combination of air knives, squeegeeing rollers and wipers.
All stages of the above process take place at temperatures ranging from ambient to a moderate 60 degrees COMS ID No: SMBI-00495966 Received by IP Australia: Time 21:30 Date 2003-11-14 14.Nov. 2003 20:23 Wallinston-Dummer Sydney No.3366 P. 16 12 centigrade, thus layer pads are not subjected to potentially distorting high temperatures.
Each zone in at least one preferred embodiment of the invention is provided with suitable drainage means beneath the conveyor system adapted to recover as much as possible of the various liquids used for subsequent filtration and reconditioning for re-use.
In at least some embodiments of the invention cleaned layer pads are stacked onto a clean pallet at the unload end of the conveyor system by the unload pick and place system up to a predetermined level at which point the pallet and cleaned layer pad stack is transferred to an automatic shrink wrapping station so as to preserve the cleanliness of the stack during subsequent handling and transport to a point of use.
The above describes only some embodiments of the present invention and modifications, obvious to those skilled in the art, can be made thereto without departing from the scope and spirit of the present invention.
