The present invention relates to a combined shipping and storage device for spooled wire, such as welding wire.
Individual spools of welding wire, which may be cored wire or solid wire, are typically packaged and shipped in cardboard boxes containing one spool of wire each. Spooled welding wire may also be shipped in multi-spool boxes, containing two or four spools per box, for example. Common spool diameter sizes include 4 inch spools, 8 inch spools, 12 in spools, and 16 inch spools, and the spools are typically made of plastic. Within the box, the spool of welding wire may further be sealed within a plastic or foil pouch or bag and/or capsule sealed by a form fitting plastic wrapping, to limit the exposure of the welding wire to humidity and other environmental contaminants.
A number of individually-boxed spools of welding wire can be shipped together to a customer. The boxes can be placed on a pallet so that they may be moved together by a forklift. The boxes are stacked on the pallet, and secured together and to the pallet, using strapping bands and stretch wrap for example. A common shipping configuration includes placing the boxes onto the pallet in layers of 9 boxes (3×3 array), up to a desired height (e.g., 5 boxes high, 6 boxes high, 7 boxes high, etc.). Thus, a pallet having layers of 9 boxes stacked 5 boxes high will support 45 boxes of welding wire for shipment.
For inventory control and quality control purposes, a customer receiving palletized welding wire may wish to inspect individual spools, and possibly every spool received. This is a very labor-intensive process and can require removal of the strapping and stretch wrap from the pallet, opening each cardboard box, opening (cutting, tearing, etc.) the plastic or foil bag, inspecting and possibly labeling the spool with inventory control information, and resealing the spool within the plastic or foil bag. The individual spools will then be taken to an appropriate storage area for later use.
A shipping device that allows for customer inspection and storage of individual spools of wire with reduced labor and material waste would be beneficial.

With reference to
The tray 10 supports a spool 14 of wire. The spool 14 can be enclosed in a pouch or bag (not shown) and/or partially enclosed by a capsule seal around the circumference of the spool, to limit the exposure of the wire to humidity and/or other environmental contaminants. The tray 10 is designed to store the spool 14 without a box, so that the wire can be quickly inspected and possibly tagged with inventory control information. Such inspection and tagging may require the spool 14 to be removed from the tray 10 and the pouch or bag opened and resealed. However, the person inspecting the wire will not have to open and handle a cardboard shipping box, and will not have to handle stretch wrapping or strapping or de-palletize/re-palletize the spools, as discussed further below.
The tray 10 can be formed from any suitable material, such as a plastic, metal, etc. However, it can be desirable to form the tray 10 from a resilient, elastomeric material (e.g., rubber, thermoplastic elastomer, etc.) to provide a degree of cushioning for the spool 14 and wire.
The tray 10 is designed to support the spool 14 mechanically, by gravity. The tray 10 includes a bottom shelf 16 onto which the spool 14 is placed. The tray 10 can be U-shaped having a U-shaped bottom shelf 16 as shown, or the tray can be semicircular, or have other shapes to adequately hold a spool of wire. The tray 10 includes a raised, U-shaped sidewall 18. The U-shaped sidewall 18 extends upward from the edge of the U-shaped bottom shelf 16. The U-shaped sidewall 18 limits the lateral movement of the spool 14 within the tray 10. The sidewall 18 can have a curved portion having a radius to closely fit the curve of the spool of wire. For example, the radius of the curved portion of the U-shaped sidewall 18 can be slightly larger than the radius of the spool 14. Extending forward from the curved portion of the tray 10 are straight portions, giving the tray its U-shape. The sidewall 18 can closely surround at least 50% of the perimeter of the spool 14. The tray 10 has an open front portion from which the sidewall 18 is omitted, to facilitate placement of the spool 14 in the tray and removal of the spool from the tray. The U-shaped bottom shelf 16 and the U-shaped sidewall 18 form the open front portion of the storage tray, extending between the terminal ends of the U-shaped sidewall. The bottom shelf 16 of the tray 10 can be U-shaped as shown, so as to include an open central portion 20 that extends inward from the open front portion of the tray toward the center of the bottom shelf surface. The open central portion 20 and the U-shaped bottom shelf 16 can allow access to a lower spool flange located in the tray. Such access to the lower spool flange can facilitate placement of the spool 14 into the tray 10 and removal of the spool from the tray. For example, the open central portion 20 in the bottom shelf 16 can provide hand/arm access to the lower spool flange, so that a person can lift the spool 14 off of the tray 10 through the open central portion 20, and pull the spool through the open front portion of the tray.
The tray 10 is shown as an open cup configuration lacking an upper ceiling surface to form a pocket for the spool 14. In other example embodiments, the tray 10 includes an upper surface that projects inward from sidewall and over the spool 14, to limit the upward movement of the spool within the tray. Such an upper surface can be a U-shaped strip that projects slightly inward from the sidewall 18, or it can extend from sidewall-to-sidewall to cover substantially the entire top surface of the spool 14 or some portion of the upper spool flange.
Atop the U-shaped sidewall 18 is an outwardly projecting lip 22. The tray 10 further includes a plurality of mounting tabs 24. The mounting tabs 24 are shown as extending outward from the lip 22, but the mounting tabs could also extend directly from the sidewall 18. The mounting tabs 24 allow the tray 10 to be mounted in a frame or rack. The frame or rack would have openings, and the mounting tabs 24 would engage the openings to fix the position of the tray 10 within the frame/rack. The lip 22 can further include openings or mounting tab recesses 26 adjacent the mounting tabs 24. It can be seen that the frontward/rearward placement of the mounting tab 24 and mounting tab recess 26 on opposite lateral sides of the tray 10 are reversed (e.g., on one side the mounting tab is located just behind the mounting tab recess, and on the opposite side the mounting tab is located just in front of the mounting tab recess). For example, a first mounting tab (right side in
In certain embodiments, the tray 10 can include a plurality of vertical buttresses 28 spaced around the U-shaped sidewall 18, to strengthen the sidewall against deformation due to outward thrusts imparted on the sidewall by the spool of wire (e.g., during shipping when the spool is subject to side-to-side movement within the tray). The buttresses 28 can be molded with the tray 10 so as to be integral with the tray, and can be located beneath the lip 22 of the tray.
The U-shaped bottom shelf 16 of the tray 10 can include curved openings 31 located just in front of the resilient spool retaining bulges 29 that extend for the length of the bulges. The curved openings 31 separate the resilient spool retaining bulges 29 from the bottom shelf 16, which allows the retaining bulges to deflect outward more freely as the spool 14 is inserted.
In certain embodiments, the resilient spool retaining bulges 29 engage the lower flange of the spool 14, but not the top flange, although the retaining bulges could engage both flanges if desired. The resilient spool retaining bulges 29 can have a slightly conical shape or upward taper, so that the lower portions of the bulges project inward into the tray 10 to a greater extent than the upper portions of the bulges. Alternatively, the resilient spool retaining bulges 29 could have no taper so that the upper portions of the bulges project inward to the same degree as the lower portions. Other configurations of resilient retaining bulges or projections will be apparent to those of ordinary skill in the art.
The cabinet 12 includes one or more doors 30 for providing access to the interior of the cabinet body. In
The cabinet 12 includes floor stands 32 that are attached to the cabinet body. To facilitate movement of the cabinet 12 using a forklift, the floor stands 32 can be mounted to a base located beneath the cabinet body, to support the cabinet body above the base. An example base for the cabinet 12 is a pallet 34. For strength and durability, the pallet 34 can be metallic, such as steel, rather than wooden. The floor stands 32 can be bolted or welded to the pallet 34, or secured in another suitable manner. The pallet 34 can include openings or fork channels 35 that are configured to receive the forks of a forklift. In certain embodiments, the cabinet 12 can include lifting eyes 36, to allow the cabinet to be moved using a crane.
One or more cabinets 12 can be mounted to the pallet 34. In
The cabinet 12 includes the trays 10 discussed above, mounted in the interior of the cabinet, and also on the interior surface of the doors 30. The trays 10 are mounted in vertical columns within a frame or rack system on the doors 30 and inside of the cabinet 12. The frame or rack system can include vertical members 38 having apertures for receiving the mounting tabs on the trays 10. The frame or rack system can also include horizontal supports 40 that support the weight of the tray and spool. In an example embodiment, the horizontal supports 40 are in the form of declined shelves that are oriented horizontally, but at a front-to-back decline, with the front edge of the shelves being higher than the rear edge of the shelves. Such shelves will support the trays from below at the proper declined angle. The horizontal supports 40 can have U-shaped openings or cut-outs corresponding to the open central portion 20 (
