1. Technical Field
The present inventions relate to reels and, more particularly, relate to a material for wrapping around a payload carried on a reel.
2. Description of the Related Art
A wide variety of products are shipped and stored on a reel, also known as a spool or bobbin. Examples of such products include wire, cable, thermocouple, fiber optics, rope, cord, and other costly material.
When these reels are shipped, the product payload, such as the wire on the spool, became damaged, for example, by a forklift fork. Replacement of the damaged products caused economic repercussions.
Attempts have been made to protect the product payload on a reel during shipment. Nevertheless shipping material on reels and providing effective protection was not always feasible. Over protection of the product amounted to additional cost such as labor, packaging equipment, nails or screws, pallets/skids. This adds additional weight which increased shipping cost. For example see the heavy wood lagging used in U.S. Pat. No. 4,850,487.
Some attempts to protect the product payload on a reel required wooden reels. This was impractical because today plastic and steel reels are sometimes required for over sea shipments, were wooden spools are forbidden.
One effective protection approach applied lagging to a reel which needed a wooden reel and additional equipment such as a nail gun, nails, and air compressor, for instance. Wood lagging added weight, was labor intensive in application, and removal and was not an environment friendly application.
Another approach was to ship all reels strapped onto pallets. When a reel was on a pallet, a forklift would lift the pallet without touching the reel. Pallets, however, consumed more space in shipping compartments than bare reels. Often one pallet would contain multiple reels. Palleted reels were also more difficult to sort distribute when multiple reels are on a single pallet.
Other approached have been tried but were either unworkable to suffered form problems including those mentioned above.
As such, there is a need in the art for such a product that addresses the problem presented by the exposed payload product on a reel. Damage from forklifts is common and may go undetected until the product is subsequently used. Thus it's critical to minimize unintentional damage and concealed forklift damage during transportation and or storage.
The present invention is illustrated by way of example and is not limited by the accompanying figures, in which like references indicate similar elements. Elements in the figures are illustrated for simplicity and clarity and have not necessarily been drawn to scale.
The details of the preferred embodiments and objects and features of the inventions will be more readily understood from the following detailed description when read in conjunction with the accompanying drawings wherein:
Concealed damage has had a very large impact on not only cost but customer satisfaction. Typically concealed damage was never detected until after a number of workers and equipment such as trenching and pulling equipment and cranes and were at work on job site and the product was being unspooled for deployment. The late detection of damage on a customized wire for specialized applications, for example, caused not only spoiling of the wire, but interruption of a job when it can be least afforded. The number of workers would be out of work and the job significantly delayed for an extended time while a replacement wire spool of this customized wire was delivered.
A guard is provided for wrapping the payload on a reel to indicate damage in the inner corners according to an embodiment. In a further embodiment the guard provides educational and warning messages.
The guard of the present inventions can:
1) minimize concealed damage because it is disposed to indicate damage in the corners were concealed damage to a product payload is most likely—the inside corners where an outside layer of the payload meets an inside end of the reel also known as the flange; and
2) Educate shipping operators such as forklift drivers with a highly visible visual aids that can be seen as the operator performs his normal operational duties. Examples of the visual messages will be later explained with reference to
This guard is a material for wrapping around the payload on a reel to mitigate damage to the payload by offering detection, protection and education. In use, for example, a forklift operation will read a message on the guard to offer education. Then if the forklift operator incorrectly handles the reel during shipment, damage to a wire or other payload will be indicated by a scrape or other visual indication on the guard. Damage is no longer concealed beneath layers of a wire payload because the material offers ready detection. Such concealed damage is particularly mitigated were the payload comes in contact to a corner at an inside side flange of the reel.
While the coating can be an ink it can alternatively be a powder that easily flakes off upon scrape or puncture. One example of an alternative coating is disclosed in U.S. Pat. Nos. 5,188,371 and 5,580,063 by Birchwood Casey used on targets to easier spot bullet penetration.
The substrate has a flat shape with top and bottom elongated edges 221 and 223 and a plurality of breaks 230 along the top elongated edge 221 to facilitate bending around the payload on the reel. A distance between the breaks 230 should be more than about 1 inch (25 mm). A distance between the breaks 230 is a range of about 4 inches (10 cm) to about 8 inches (20 cm). A distance between the breaks is preferably about 6 inches (15 cm).
The breaks 230 are preferably v-shaped notches as illustrated in the embodiment of
The substrate has additional breaks 240 along a bottom elongated edge to create an octagon or “stop sign” shape in the embodiment of
A width of the substrate from top elongated edge 221 to bottom elongated edge 223 is approximately equal to the distance between the breaks 230.
The substrate in the embodiment of
An outer surface of the substrate 260 is a visually scratchable. This visually scratchable surface 260 can be accomplished by a coating of a kind capable of being scratched and visually indicate damage. A scratch can comprise both a scrape on the surface of the material and a puncture through the guard material. The guard material serves to identify damage. It is important that this surface is capable if indicating damage of the kind of force produced by a shipping tool such as a fork on a forklift truck. In a preferred embodiment the visually scratchable coating 260 comprises a water based ink which exhibits a contrasting color relative to a color of a surface of substrate such as an orange color on a white color beneath. Additionally the surface is of a kind where an abrasion from an object such as the iron of a fork of a forklift truck will mar the surface and leave some dark iron marks behind on the guard. Thus a color of the outer surface of the substrate should be contrasting in color with that of objects that are likely to hit reels.
The embodiment of
When the guard indicates damage, the payload can be inspected for damage. A notation can be written on the guard next to the damage mark to indicate the payload has been confirmed as good despite the damage. With a wire or cable payload, for example, when damage is indicated on the guard, the wire or cable can be electrically tested form end to end.
My invention will aid forklift operator in proper handling of a reel, therefore reducing the risk of damage to the product. The unique design as described will be able to fit on as small a reel with a traverse length as small as about 4.5 inches (10 cm) and a flange diameter as small as about 9 inches (23 cm). This leaves a circumference of no more then about 24 inches (55 cm) for a product space leaving not less than about 1.5 inches (3.5 cm) from the most outer layer of product to the end of the flange for proper shipping and application. The unique design as described will also be able to fit on any larger reel.
Tools required for use of the guard are of the same standard supplies you will find in everyday distribution warehousing/shipping facility, such as clear tape, shrink wrap and or industrial packaging staples, making my invention less labor intensive (low cost) to apply and will add minimal additional weight. Staple lengths of about ⅜ inches (10 mm) to about ½ inches (12 mm) should do, though longer staples will work. Typically the thickness of the guard would be about ⅛ inches (3 mm), thus longer than ⅛ inches (3 mm) staples would be needed. This in turn will help reduce or keep shipping cost.
Breaks 440 along a top elongated edge of the guard 420 should be of a size and configuration to facilitate securing to inner flanges of the reel 410. A bent elongated edge of the guard 420 is secured against the inside surface of the flange of the reel 410. The staples penetrate through the material of the guard 420 towards the inside surface of the flange of the reel 410 and into the material of the reel 410. A wood or other relatively soft material is need in the flange for stapling.
When a reel has flanges made of a hard material, such as metal or hard plastic, stapling the guard 420 to the reel 410 is impractical. Besides stapling, the guard 420 can be secured or adhered to an inner flange of the reel 410 in other ways, such as taping with clear packing tape or plastic shrink wrapping. The embodiment of
A guard for plastic and steel reels in addition to wood reels is needed because sometimes on oversea shipments, were wooden spools are forbidden due to wood boring insects, for example.
For application, the product payload is placed on a reel 510. Then the payload is wrapped with shrink wrap. Thereafter the pre-fabricated guard 520 is bent at an approximately 90 degree angle, facing the visual aid out on the product. The guard 520 is then placed in the inside corner where the product edge meets with the inside flange covering the exposed product area. Then a reinforced packing tape, such as that manufactured by Inter Tape polymer group, commonly known as shrink wrap, is wrapped around the exposed product payload and an overlapping portion 531 of guard 520. The width of the overlapping portion 531 is dependent on visual aid messages. It is preferable that the wrap does not cover the visual aid warnings as illustrated in
In an alternative implementation, the guard 520 can be adhered to the inside flange of the reel 510 by clear adhesive packing tape 550 but without the shrink wrap 530. Or alternatively the guard 520 can be adhered to the inside flange of the reel 510 by clear the shrink wrap 530 but without the adhesive packing tape 550.
Assuming conventional protective wrapping methods were used such as shrink wrap, chip board, corrugated card board or any such product is applied between the reel flanges, there would be a small gap that was still exposed. This is where forks from forklift trucks do the most damage during moving and handling. The embodiments herein address and solve these and other problems caused by improper handling. The embodiments herein also can function as a highly visible warning and teaching message to illustrate proper handling procedure that can easily been seen by the folk lift operator during normal operation.

The octagon shape symbolizes a stop sign. This universal, visual precautionary shape is reminiscing to a halt/stop or caution sign, which is customary to everyone. The messages preferably contain an example of how to best carry a reel with a fork of a forklift and a ‘do not symbol’ icon overlay on a picture of how not to lift a reel with a forklift. The ‘do not symbol’ icon overlay is a circle with a diagonal line through it (running from top left to bottom right) surrounding a pictogram as specified by ISO 3864-1. It is also know as a prohibition sign, the no symbol, the prohibition sign, the circle-backslash symbol, or universal no.
Throughout where we refer to a reel we intend to also refer to alternate synonyms for a reel such as a spool and a bobbin.

The breaks 1030 along the top elongated edge 1021 are of a size and configuration to facilitate securing to an inner flange of the reel such as by stapling, taping or plastic shrink wrapping. A distance between the breaks 1030 should be more than about 1 inch (25 mm). A distance between the breaks 1030 is a range of about 4 inches (10 cm) to about 8 inches (20 cm). A distance between the breaks 1030 is preferably about 6 inches (15 cm). A depth or length of each of the breaks 1030 from the top elongated edge 1021 to a perforated fold line 1050 should be more than about ¼ inch (6 mm). A depth of each of the breaks 1030 is about 1.5 inches (38 mm). A depth of each of the breaks 1030 is preferably about ¼ inch (6 mm).
