Description

FIELD OF INVENTION

The present invention is related in general to pallets and, in particular, to a pallet designed for holding, storing and transporting sheets of steel and other materials.

BACKGROUND OF THE INVENTION

Traditional wooden and plastic pallets lack the durability and strength necessary for stacking metal sheeting. Currently, industry standards include banding stacks of metal sheets and inserting pieces of lumber between each banded stack to create a point of insertion for a forklift. The present methods lack uniformity and limit how high banded stacks can be built up and stacked. Further, current methods are wasteful in terms of space requirements and labor resources and they create workplace safety issues as a great deal of time and effort are spent manually transporting and handling steel sheets.

Based on the foregoing, there is a need for an improved system for stacking and storing metal sheeting. A system in which metal sheeting may be stacked uniformly by providing a structure that holds stacks of metal sheets and prevents shifting is needed. Such a system would allow the user to: easily transport and store metal sheeting; stack pallets of metal sheeting in a safe, uniform manner; and allow the sheeting to be loaded directly into an automation machine for laser cutting if desired. The present invention overcomes the prior art shortcomings by accomplishing these critical objectives.

SUMMARY OF THE DISCLOSURE

To minimize the limitations found in the prior art, and to minimize other limitations that will be apparent upon the reading of the specifications, the preferred embodiment of the present invention provides a system for stacking, storing, and loading metal sheets.

In accordance with a preferred embodiment, the present invention provides a pallet which includes multiple posts that allow alignment of sheets of material on the pallet. Preferably, the pallet further includes posts which include stacking bells which allow the pallets to stack together while preventing damage to loaded materials. In accordance with one preferred embodiment of the present invention, the pallets may be stored in a specially designed rack.

These and other advantages and features of the present invention are described with specificity so as to make the present invention understandable to one of ordinary skill in the art.

Further, the pallet 100 preferably includes a pallet end stop 135 and a rail end stop 130

With reference now to FIG. 2, a top view of the exemplary pallet will now be further discussed. As shown, the pallet 200 preferably includes a front rail 220, a back rail 225, a left support rail 210 and a right support rail 211. Preferably, fork pockets 215a-d are provided which run through the front rail 220 and the back rail 225. As shown, the exemplary pallet 200 further includes support posts 240a-f which are spaced around the outer rails of the pallet 200. As further shown, support posts 240a, 240c, 240d and 240f on the corners of the pallet 200 preferably further include respective stacking bells 242a, 242c, 242d and 242f to allow for the stacking of pallets as discussed further below. Additionally, pallet 200 preferably further includes a pallet end stop 235 and internal rails 227.

As further shown in FIG. 5A, the rack 500 further includes lateral shelving slots 556 for receiving multiple steel pallets which can slide into the shelving slots 556 from either side of the rack 500. According to a preferred embodiment, the lateral shelving slots 556 are preferably spaced such that any pallet being lifted and removed will not contact the pallet being stored above it. According to a further preferred embodiment, the height of the lateral shelving slots 556 may preferably be limited so that any pallet being removed will contact the top of the slot before the posts on the lifted pallet can contact the bell(s) of the pallet being stored above it. This spacing and height restriction may preferably be used to eliminate the safety risk of mistakenly removing two pallets at one time and overloading the forklift. According to a preferred embodiment, the lateral shelving slots 556 are preferably spaced such that any pallet being lifted and removed will not contact the pallet being stored above or below it.

With reference now to FIG. 8, an enlarged view of the area A shown in FIG. 7 will now be discussed. As shown in FIG. 8, the front rail 545 may be connected to vertical post 501c via a fastener 534. As further shown, the shelving slots 556 may be formed from L shaped lateral brackets.
