Abstract
Description
- The present invention relates generally to a container for shipping and dispensing rolled material and, specifically, to a conveyor belt field splicing dispensing container.
- Conveyor belts are commonly used as a means to move material from one location to another. In large mining operations, the conveyor belt is generally formed of a rubber body embedded with steel cords or strands or textile reinforcement. A cover compound can be used at the surface wherein the material is to be conveyed. Generally the compound is abrasions and cut resistant and of sufficient thickness to prevent the rocks being conveyed from tearing the belt. A pulley compound can be used on the interior surface and is ideally suited for improved wear as the belt traverses over the pulleys used to drive the belt.
- The steel corded or stranded belts may extend several miles and cost millions of dollars to fabricate and install. The fabrication of such belts occurs initially at a factory wherein steel strands or cords are arranged in a coplanar relationship parallel to the surface of the belt so that the belt will exhibit uniform expansion and minimize weaving that can otherwise damage the belt as it traverses its designated route.
- The prior art method of fabricating belts requires the steps of vulcanizing the rubber belt and winding it onto large spools for shipping to the site. Once the spools of the belt are received at the site, the ends must be prepared for splicing by removing the vulcanized rubber from the strands over a distance determined to be sufficient to provide enough joint length to make a secure splice.
- Removal of the rubber can be a very time consuming and tedious task. Often time's piano wire is used to peel the vulcanized rubber from the strands. In large belts of several feet in width over a hundred strands must be exposed at each joint end. Once exposed, the strands had to be cleaned of as much of the vulcanized rubber as possible. Various alternative methods of splicing a conveyor belt have been proposed in order to expedite and simplify the process. U.S. Pat. No. 3,487,871 teaches a joining member having a plurality of strand receiving grooves. Such a method for effecting a splice, however, proved less than optimal because the number of grooves must equate with the number of strands in the belt. Since conveyor belts are of not standardized in width, a custom connector member must be used for each size belt.
- An improved method of effecting a splice between ends of a conveyor belt has been proposed comprising the steps: (a) removing a portion of the rubber from the belt ends to be joined exposing a plurality of strands; (b) providing at least two unvulcanized strips of rubber at least one strip being a bottom strip having a plurality of substantially parallel strand receiving grooves on an upper surface and the other strip being a top strip; (c) placing exposed strands of the belt ends being joined in the grooves of the bottom strip; (d) placing the top strip overlying the bottom strip and vulcanizing the strips together thereby forming the spliced joint. The strands may be at least partially sheathed in the vulcanized rubber.
- To utilize the foregoing method, a preform splice is used, consisting of a multiple (e.g. 21 inch) uncured insulation gum slabs each having longitudinal grooves formed on one side into which the splice cords are laid. The groove spacing and diameter are carefully controlled. The preform slab is fabricated into rolls that are shipped to an end user that removes the roll from shipping container. Once removed, the user unrolls a desired length of material and scores the material. The free end portion of material is then manipulated until breakage along the score line occurs. The remaining roll of the material is then stored until needed for the next splice.
- The quality of the resultant splice is influenced by a number of factors. First, the dimensional accuracy of the length of cut must be controlled for a high quality splice. Secondly, the dimensional and structural integrity of the roll must be protected and maintained. Damage to the roll can occur from handling during shipment, removal from its shipping container, during the cutting operation, or subsequent storage of the roll between repair occasions. Such damage to the roll can affect the structural integrity and performance the splice material removed therefrom and of the splice made therewith. A need, therefore, exists for an improved method for protecting the integrity of a roll of splice material from structural damage during its shipment to a field site, its use at the site, and in subsequent storage. The method should further accommodate convenient and accurate removal of desired lengths of splice material while protecting the material from damage. In addition, the method should facilitate easy and ergonomic transportation and dispensing of splice material from a roll source at a minimum cost.
- The present invention provides shipping and dispensing container for a roll of sheet material such as, but not limited to, a roll of material used in field splicing conveyor belt ends together. The container comprises a body reconfigurable between a shipping configuration in which the roll of material is enclosed and a dispensing configuration in which an access passageway is exposed. A free edge portion of the roll may be withdrawn through the passageway in the dispensing configuration. A container sidewall portion is pivotally attached to the container body and pivots to an open position to expose the passageway in the dispensing configuration and to a closed position in the shipping configuration to close off the passageway. Pursuant a further one aspect of the invention, the side wall portion enclosing the passageway is substantially horizontal in the open position and may be supported by at least one leg, whereby forming a worktable. The free end of the roll may be drawn across the worktable and scored at an appropriate location. The side wall portion and the support leg may be pivoted against the container in storage positions when the container is transported between fieldwork sites.
- According to another aspect of the invention, the roll of material may optionally be dispensed from the top within the container or inverted and dispensed from the bottom. Appropriate guide rollers are provided to direct the free edge portion of the roll to the passageway in either roll orientation.
- Yet another aspect of the invention is to provide means for regulating the speed at which the roll material is withdrawn from its roll. The roll is provided with a pivot shaft having protruding opposite ends resident within a respective slot channel in opposite side panels. The speed regulation means in one embodiment represents a cable disposed to exert controlled pressure upon the roll of material to reduce the rate at which the material is withdrawn.
- Pursuant to yet a further aspect of the invention, a method of shipping and dispensing a roll of sheet material is provided, comprising the steps: rotatably seating the roll of sheet material within a container body, the body including a plurality of side panels defining therebetween an internal chamber dimensioned to receive the roll of sheet material; configuring the container body to substantially enclose the roll of sheet material in a shipping orientation; providing an access passageway through the container body through which a free edge portion of the roll of material may be withdrawn, the access passageway being enclosed by a side panel portion pivotal between a closed position substantially covering the passageway and an open position substantially exposing the passageway.
- The invention will be described by way of example and with reference to the accompanying drawings in which:
- FIG. 1 is an exploded perspective view of the subject container shown with the access door in the closed position;
- FIG. 2 is an exploded perspective view of a material roll and the subject container shown with the access door in the open, worktable orientation.
- FIG. 3 is a partially assembled perspective view thereof shown with the lid removed and in a dispensing configuration;
- FIG. 4 is a transverse section view through the center of the subject container;
- FIG. 5 is a longitudinal section view through the center of the container;
- FIG. 6 is a transverse section view of the container with the access door in a partially distended position.
- FIG. 7 is a longitudinal section view of the container with the free edge portion of the roll extended across the work surface provided by the access door.
- Referring initially to FIGS. 1 and 2, the subject container for transporting and dispensing roll material is shown at10. The
container 10 comprises an elongate quadrilateral body havingend panels side panels bottom floor panel 20. Alid 22 is provided to enclose aninternal compartment 23 of thecontainer 10 defined bysides floor panel 20. - A
reinforcement edge flange 24 is provided to extend upward from thefloor panel 20 along each corner of thecontainer 10. Threeelongate support flanges floor panel 20 and extend across thecontainer 10.Reinforcement panels 31 are affixed to the container against outward surfaces ofside panels side panel - Extending downward into the midsection of each
side panel narrow guide slots slots lower slot end 38. Mounted to the interior wall of eachpanel support rollers - A
door panel 50 is pivotally coupled to theforward end panel 12 athinge 52 and covers a generally rectangular through-passageway 54 that communicates with theinterior compartment 23. Mounted along opposite sides of thedoor panel 50 aresupport legs 56. While preferably twosupport legs 56 are utilized, more or fewer legs may be employed if desired. Thesupport legs 56 are elongate and hinge to upper corners of thedoor panel 50. In the storage, or shipping configuration, represented in FIG. 1, thelegs 56 collapse along thepanel 50 and align with the vertical reinforcement edges strips 24 extending along opposite sides of thepanel 12. Thedoor panel 50 pivots outward into generally a horizontal disposition as shown in FIGS. 2-7, representing a dispensing configuration. Eachleg 56 has anabutment shoulder flange 60 at a top end. In the dispensing configuration thelegs 56 are pivoted downward, theabutment flange 60 of each leg abuts an underside of thesupport panel 50. Thelegs 56 are thereby positioned to support thepanel 50 on a work surface in a horizontal attitude. Thepanel 50 thus becomes a work table positioned adjacent topassageway 54 andpassageway 54 provides an unobstructed access into thecompartment 23 - The
lid component 22, as best seen from FIG. 1, is generally rectangular comprising acentral panel 62 having peripheralreinforcement edge flanges 64 affixed to an upper surface. Extending transversely across an underside of thelid panel 62 areend reinforcement flanges 66. - As seen from FIGS.2-7, a
material roll 68 is intended for residence within theinternal compartment 23 ofcontainer 10. While various types of rolled materials may be utilized in accordance with the invention, the invention has particular utility in the shipping and dispensing splice material for field splicing a conveyor belt.Such material 70 is wound around an,axial spool 72 through which anaxial pivot shaft 74 extends. End portions of thespool 72 project outward a distance from edges of thematerial roll 70 andend portions pivot shaft 74 project outward a distance from the ends of thespool 72 as shown. Thepivot shaft 74 may be eliminated by using another method of winding such as surface winding. Thematerial 70 is formed of a non-vulcanized rubber compound and may have a liner formed from suitable material such as polycarbonate laminated to one or more surfaces. Thematerial 70 is intended to splice together ends of a belt such as a conveyor belt having longitudinal cords disposed therein. Lengths of material are removed from theroll 70 as needed in the creation of a splice preform consisting of a wide (e.g. 21 inch) uncured insulation gum slab having longitudinal grooves formed on one side into which the splice cords are laid. In order to function as intended, it is important to maintain the structural and geometric integrity of thematerial roll 70 during shipment to and from a field work site, while dispensing material, and during subsequent storage between splice jobs. Fully wound, the spool and material roll weigh a substantial amount. Should such weight be brought to bear upon the material surrounding the spool in a misdirected manner, a tearing, folding, or collapse of the material sheet could result. Making a high quality splice from material so damaged would, accordingly, be rendered more difficult or impossible altogether. - Referring to FIGS. 3, 4, and5, the
material roll 68 is inserted into theinternal compartment 23 of thecontainer 10 with thelid 22 removed therefrom. Theend portions slots spool 72 supportively engage therollers spool 72 in a centered location within thecompartment 23.Screws 80 are provided extending throughapertures 82 of theside panels - As will be noted, the
roll 68 may be positioned within thecompartment 23 uponrollers free edge portion 84 of the roll can be withdrawn from the top and unrolled in a forward direction. Preferably, however, theroll 68 is positioned as shown in the inverted position such that theedge portion 84 is withdrawn from the bottom. A bottom feed reduces the extraction force required to rotate the roll when the roll is full because the weight of the spool and the full roll is not bearing upon theedge portion 84. Thefree edge portion 84 may be drawn upward and fed through thepassageway 54 whereby exiting theinternal compartment 23. With thedoor panel 50 in the upright, or closed position, the container assumes a transportation configuration in which theroll 68 is centered, supported, and enclosed within thecompartment 23. Thematerial 70 is thereby protected from contact with surrounding structure and damage that may result therefrom during transit and storage. Bending, damage, or tearing of the material 70 that might otherwise occur is avoided and the quality of subsequent splices made from the material is not compromised. - The
door 50 is positioned in the table configuration shown in FIGS. 3-7 prior to withdrawal of theroll edge portion 84. So positioned, the container assumes a dispensing configuration in which theedge portion 84 may be withdrawn threw thepassageway 54 in a flat, undamaged condition and across thedoor panel 50 that is adjacent thereto. Thedoor panel 50 protects and supports the free edge portion during the withdrawal procedure. As the edge portion is drawn over thedoor panel 50, astraight edge 86 may be positioned transversely across theedge portion 84, a cut is made through the material. A score line is made thereafter along the straight edge through the liner material. Theedge portion 84 may thereafter be manually manipulated along the score line until a clean break results. - As more splices are made and the
roll 68 is diametrically reduced, the speed at which thematerial 70 is withdrawn may increase to an undesirable level. In order to place drag on the rotation of theroll 68, speed regulation means in the preferred form of an elastomeric cable orband 88 may be utilized. Theband 88 may be formed specifically for the application out of elastomeric material such as rubber or a commercially available band such as a “bunge” cord may be employed. Theband 88 is attached as shown in FIG. 7 atend tie downs end panels 12, 14 amidsection 94 is drawn across thespool 72. The force applied against the spool and the frictional drag resulting therefrom may be adjusted by an appropriate selection of band length. As thespool 72 rotates, theband 88 frictionally impedes rotation and slows the spool rotation to a desired level. - After a field splice has been completed, the
free edge portion 84 is placed inside thecompartment 23 and thedoor panel 50 is pivoted from the horizontal, dispensing orientation into the closed position shown in FIG. 1. A latch (not shown) may be employed in conventional manner to releasable lock the door in the closed position. The roll of material may thereafter be safely transported to another work site or stored within the container fully protected from damaging contact with surrounding objects. - From the foregoing, it will be appreciated that the subject container is economical to manufacture. The container may be formed from conventional materials such as wood, plastic, or metal by conventional means. The container further does not require a center shaft to support the roll of material therein, thereby reducing its weight and resultant cost of manufacture and shipping. Also, the container serves as both a shipping container and a dispensing container, fully protecting the roll during transit yet allowing for a protected withdrawal of material in the dispensing mode of operation. The door converts into a table surface as needed to support the material during the scoring and cutting operation. Maintaining the splice material in a flat, non-deformed condition assures that the grooves extending along the splice are maintained in a linear and uniform condition. The grooves thus are in condition to readily receive the belt cords therein and a high quality spice may be achieved. Finally, as discussed, the container functionally accommodates either an upright orientation of the roll therein for top withdrawal of material or an inverted orientation of the roll for a bottom feed of material.
