Abstract
Description
- This application is a divisional of U.S. patent application Ser. No. 10/322,025 filed on Dec. 17, 2002.
- Not Applicable.
- The field of invention is conveyor systems, and more particularly, a method of forming return rollers used in endless chain or belt conveyor systems.
- An endless conveyor chain or modular belt passes over a conveyor frame from a frame tail to a frame head to convey a product, and returns to the frame head beneath the frame in an endless loop. When the conveyor chain or belt returns beneath the conveyor frame, the chain or belt must be supported to prevent the chain or belt from striking the ground or some other object beneath the conveyor frame.
- Unpowered return rollers are often used to support the return portion of the chain or belt. In many cases, the return rollers are special mechanical assemblies made by pressing bearings into the ends of a polyvinyl chloride (PVC) or steel pipe. These rollers often would not turn despite the bearings which resulted in the roller being unevenly worn down by the conveyor. In addition, a plain PVC pipe slide over a metal shaft without bearings is known.
- A known roller provided by Marbett Conveyor Components is coated with a high friction material, such as rubber, which engages the conveyor chain return to force the roller to rotate. This reduces the problem of uneven wear on the roller. Unfortunately, the Marbett rollers are injection molded which limits the roller length. As a result, multiple rollers are required to accommodate wide chains or belts.
- Another problem associated with the return rollers is debris and dust which can be caught between the return roller and belt or chain. The debris can become embedded in the roller, belt, or chain which can cause premature wear and failure. Therefore, a need exists for an improved return roller for use in belt or chain conveyor systems.
- The present invention provides a method of making a return roller for use in a conveyor system. The method includes extruding an elongated cylindrical core defining a radially outwardly facing surface, and coextruding a coating onto the at least a portion of the radially outwardly facing surface of the core. The coating is preferably coextruded with at least one discontinuity formed in the coating to provide debris relief and indicate wear of the coating.
- An objective of the present invention is to provide coated return roller which can be formed in any length. This objective is accomplished by coextruding at least the portion of the cylindrical core defining the radially outwardly facing surface with the coating.
- Another objective of the present invention is to provide a return roller which is not adversely affected by debris. This objective is accomplished by forming discontinuities in the coating to provide debris relief.
- The foregoing and other objectives and advantages of the invention will appear from the following description. In the description, reference is made to the accompanying drawings which form a part hereof, and in which there is shown by way of illustration a preferred embodiment of the invention.

FIG. 9 is a cross sectional view of another embodiment of a return roller incorporating the present invention. - As shown in
FIG. 1 , aconveyor drive system 10 includes anendless conveyor belt 12 driven by adrive sprocket 14 that is rotatably coupled to drive motor 16 by a drive belt 18. Theconveyor belt 12 travels over anupper support 20 between anidler sprocket 22 and the drive sprocket 14, and returns beneath theupper support 20 as it travels between thedrive sprocket 14 and the idler sprocket 22. Areturn roller 30 supports thereturn section 24 of thebelt 12 to support theconveyor belt 12 beneath theupper support 20 Although tworeturn rollers 30 are shown, one or more return rollers can be provided without departing from the scope of the invention. The term belt used herein shall be construed to include chains. - Referring to
FIGS. 2-4 , thereturn roller 30 includes anextruded roller core 32 on which acoating 34 is coextruded. Advantageously, by coextruding the coating over the cylindrical core, the roller can be formed having any length desired or formed having a standard length which can be cut to the desired length. In preferred embodiments described below, thecoating 34 includes at least onediscontinuity 36 which can provide debris relief or indicate wear that requiresroller 30 replacement. - The
roller core 32 shown inFIGS. 2-4 is formed from a rigid material, such as glass reinforced polypropylene, or other thermoplastic material including PVC, and includes an outercylindrical shell 38 joined to an innercylindrical shell 40 byspokes 42 extending radially between theshells cylindrical shell 38 defines a substantially continuous radially outwardly facingsurface 44. Although threespokes 42 is preferred to provide sufficient support for the outercylindrical shell 38 with a minimum use of material, any number of spokes can be provided without departing from the scope of the invention. In this embodiment, theroller core 32 is formed as a single piece, however, as described below, theroller core 32 can be an assembly formed from separately formed parts without departing from the scope of the invention. - The
coating 34 is coextruded onto the radially outwardly facingsurface 44 of the outercylindrical shell 38. Preferably, thecoating 34 is a thermoplastic rubber or urethane that has a high coefficient of friction compared to thecore 32, such that the interaction between thereturn section 24 and theroller 30 will cause the roller to spin and prevent uneven wear. In certain applications, however, it may be advantageous to use a hard, wear resistant material for thecoating 34, such as PVC, polyamide, acetal (POM), or polybutylene terephthalate (PBT) in abrasive environments. - Preferably, the
coating 34 chemically bonds with theroller core 32 to fix thecoating 34 relative to thecore 32. Although chemically bonding thecoating 34 to theroller core 32 is preferred, materials can be used which do not chemically bond, or only form a weak chemical bond, without departing from the scope of the invention. If thecoating 34 does not chemically bond to theroller core 32, thecoating 34 can be fixed to theroller core 32 using a shrink fit, a mechanical bond, and other methods known in the art without departing from the scope of the invention. - The plurality of axially extending, radially spaced
discontinuities 36 are formed in thecoating 34 for debris relief. Thediscontinuities 36 provides a space for debris disposed between theroller 30 andconveyor belt 12, such that the debris is not pressed into theconveyor belt 12 orroller 30 and can fall harmlessly to the ground as theroller 30 rotates. Advantageously, thediscontinuities 36 can also function as wear indicators to provide maintenance personal with notice that theroller 30 needs replacement. Although a plurality ofdiscontinuities 36 is preferred, one ormore discontinuities 36 can be provided without departing from the scope of the invention. In the embodiment disclosed inFIGS. 2-4 , thediscontinuities 36 do not extend the entire depth of thecoating 34, however, as disclosed below, thediscontinuities 36 can be formed by applying the coating in axially extending strips on the radially outwardly facingsurface 44 of thecylindrical core 32 exposing portions of thecylindrical core 32. - The
roller 30 rotates on a shaft 46 (shown inFIG. 1 ) extending through the innercylindrical shell 40. Theshaft 46 can be fixed at both ends, such that it does not rotate. In this case, brass bushings (not shown) can be provided to increase wear resistance. The brass bushings can be provided at the ends of innercylindrical shell 40 or theroller core 32 can be extruded over a brass bushing extending the entire length of theinner surface 48 of the innercylindrical shell 40. Although a single shaft extending through the roller is preferred in certain application, short shafts inserted into each end of the roller may be preferred if the roller core is sufficiently rigid to support the load imposed on the roller by the return belt. - In applications where no relative movement between the
shaft 46 androller 30 is desired, theshaft 46 can be rotatably mounted using bearings (not shown), such that theroller 30 can rotate with theshaft 46. In this application, theroller 30 can be fixed to the rotating shaft using a key, square shaft in a square bore, or by bonding the roller to the shaft using adhesives, fasteners, and the like. - In an alternative embodiment disclosed in
FIGS. 5 , a return roller 50 includes aroller core 52 having an innercylindrical shell 54.Spokes 56 extending radially outwardly from the innercylindrical shell 54 have distal ends 58. The distal ends 58 define a discontinuous radially outwardly facingsurface 60. Acoating 62, a such as described above, is chemically bonded to the spoke distal ends 58 for engagement with thereturn belt 24.Discontinuities 64 in thecoating 62 are formed between thespokes 56, and correspond to discontinuities in the radially outwardly facingsurface 60, to provide debris relief. - In another alternative embodiment disclosed in
FIGS. 6 and 7 , areturn roller 70 includes anmultipart roller core 72. Theroller core 72 is an assembly having an innercylindrical shell 74 including radially outwardly extendingspokes 76 having distal ends 78. The spoke distal ends 78 are received ingrooves 80 formed in a radially inwardly facingsurface 82 of an extruded outercylindrical shell 84. Of course, thespokes 76 can be fixed to the outercylindrical shell 84 using methods known in the art, such as a friction fit, adhesives, and the like without departing from the scope of the invention. - A
coating 86, such as described above, is coextruded onto a radially outwardly facingsurface 88 of the outercylindrical shell 84 in the form of axially extending strips. Axially extendingdiscontinuities 90 formed between the strips ofcoating 86 expose the radially outwardly facingsurface 88 of the outercylindrical shell 84. - In yet another embodiment disclosed in
FIG. 8 , anend cap 92 is provided over eachend 94 of acylindrical core 96, such as described above, to prevent debris and dust from collecting between thespokes 98.Arms 100 extending axially from thecap 92 extend into thecylindrical core 96 to provide a snap fit that holds thecap 92 over thecore end 94. Of course, other methods for joining theend cap 92 to the cylindrical 96 core can be used, such as adhesives, fasteners, and the like, without departing from the scope of the invention. Advantageously, the end caps 92 can extend radially past the coating to form flanges which can act as guides to keep the belt in contact with the roller. - In yet another alternative embodiment disclosed in
FIG. 9 , thecylindrical core 102 has an inner cylindrical shell 104 formed with a radially inwardly facingsurface 106 having a square cross section. Advantageously, the non-circular cross section can be provided when no relative movement between the shaft and roller is desired. - While there have been shown and described what is at present considered the preferred embodiments of the invention, it will be obvious to those skilled in the art that various changes and modifications can be made therein without departing from the scope of the invention defined by the appended claims.
