Abstract
A modular belt having a first belt module and a second belt module intercalated and locked into position by a pivot rod having a head at one end and a retaining ring disposed in spaced apart relation relative to the head along the longitudinal axis.
Description
- The present application is a continuation of U.S. patent application Ser. No. 10/891,807 filed on Jul. 15, 2004 which claims priority to U.S. Provisional Patent Application No. 60/489,824 filed Jul. 24, 2003, entitled “Rod Retaining Snap Rod with Enlarged Retaining Ring,” which is incorporated herein by reference.
- The present invention relates to modular conveying apparatus.
- Because they do not corrode, are light weight, and are easy to clean, unlike metal conveyor belts, plastic conveyor belts are used widely, especially in materials handling and conveying food products. Modular plastic conveyor belts are made up of molded plastic modular links, or belt modules, that can be arranged side by side in rows of selectable width. A series of spaced apart link ends extending from each side of the modules include aligned apertures to accommodate a pivot rod. The link ends along one end of a row of modules are interconnected with link ends of an adjacent row. A pivot rod journaled in the aligned apertures of the side-by-side and end-to-end connected modules forms a hinge between adjacent rows. Rows of belt modules are then connected together to form an endless conveyor belt capable of articulating about a drive sprocket.
- The retention of the pivot rod is an important feature of the modular plastic conveyor belts. Rod retention can be accomplished by enlarging the heads of the pivot rods at both ends but such would not allow for disassembly without destroying the rod head. Headless rods have been used for easier production and belt assembly. These type of rods must be blocked at both ends of the belt during use. In addition headless rods are often difficult to remove for disassembly.
- One approach to rod retention is to have a head at one end of a rod and a headless section at the opposite end. The headed rod is furnished with a rod retaining ring disposed on the shaft at a distance from the head portion of the rod. The rod is inserted through the pivot holes of the module links, which are all exactly the same diameter. The retaining ring is just a little bit larger in diameter than the pivot hole of the outermost link, such that the ring may be forced through the pivot hole of the outermost link end and is able to expand behind the link. In this arrangement the rod is kept firmly in position by the retaining ring. The system described above has the drawback that it requires tight tolerances of the hole diameter of the outermost link and the retaining ring diameter. In practice, there is a risk that the rod does not retain well enough or is retained tightly and cannot be easily disassembled. In addition, if the retaining ring is a little too large, it may be sheared off when inserted.
- What is needed is a device that makes the above-described tolerances less critical.
- The present invention meets the above-described need by providing a snap rod system such that the retaining ring can be made larger in order to increase the size of the shoulder which engages behind the link face. At the same time due to the larger ring diameter the bore of the outermost link needs to be enlarged accordingly in order to allow the larger retaining ring to be moved through the bore. Due to the larger difference between the retaining ring and the rod diameter, the tolerance becomes less critical. In one embodiment, the bore of the outermost link end is slightly eccentric in such a way that the enlarged shoulder of the retaining ring will be clearly overlapping the link face when assembled. When the belt is under tension the rod will be firmly forced into this retaining position, without losing the ability to transmit the belt pull.

FIG. 8 is a cross-sectional plan view of an alternate embodiment of the present invention. - In
FIGS. 1-4 , amodular belt 10 is formed from a plurality of belt modules as will be evident to those of ordinary skill in the art. InFIG. 1 , theoutermost modules belt 10 may be formed into varying widths in bricklayed fashion in a direction perpendicular to the direction ofbelt travel 34. - Each
module module body 20 with a first and second plurality oflink ends outer edge 12 shown at the top ofFIG. 1 . Each link end 22, - has opposed
side walls transverse thickness 21. The firsttransverse thickness 21 is connected to theintermediate section 26 of themodule body 20 at a firstproximal portion 27. The transverse thickness extends from theintermediate section 26 in a direction of belt travel to a firstdistal portion 29. - The link ends 22, 25 include
openings belt travel 34. Theopenings pivot rod 19 whenadjacent belt modules - The
pivot rod 19 is typically round and has adiameter 30 such that themodules pivot rod 19 has anend portion 46 with adiameter 47 that is greater than thediameter 30 of thepivot rod 19. Thepivot rod 19 also includes aretaining ring 60 spaced apart longitudinally from theend portion 46. Theretaining ring 60 has a diameter Dr that is larger than the diameter of thepivot rod 19 and may be formed with a chamfered orbeveled edge 63. -
Outermost link end 40 ofmodule 16 is disposed toward theedge 12 ofbelt 10. The outermost link end - has a
recessed portion 43 that is capable of receivingend portion 46 ofpivot rod 19. When thepivot rod 19 is installed in thebelt 10 in the direction indicated byarrow 49, theend portion 46 is received in therecessed portion 43 and abuts with the portion of the linkend surrounding aperture 52 as shown inFIG. 4 . -
Link end 40 has anopening 52 with a diameter D1 that is approximately equal to or slightly smaller than the diameter Dr of thering 60 but is larger than the diameter D2 ofopenings -
Belt module 13 also has a specially formedoutermost link end 55 having arecessed surface 56. - The central
longitudinal axis 65 ofaperture 52 is offset from the centrallongitudinal axis 67 ofopenings pivot rod 19 is bent as shown inFIG. 3 . Thepivot rod 19 is bent during insertion such that once thering 60 clearsaperture 52, the enlargedshoulder 75 overlaps the linkface surrounding aperture 52 as shown in the circledarea 76 inFIG. 4 . The axial misalignment between theapertures ring 60 does not exit from the alignedmodules -
FIGS. 2-4 illustrate the position of thepivot rod 19 and themodules pivot rod 19. InFIG. 2 , thepivot rod 19 is shown at the maximum insertion point prior to bending the body or shaft of thepivot rod 19. Therod 19 has been inserted in the direction ofarrow 49 until thebeveled edge 63 of the retainingring 60 engages with the edge of theopening 52 on the left hand side of the figure. - Turning to
FIG. 3 , deflection of thepivot rod 19 to the right side of opening 52 causes thepivot rod 19 to bend such that the retainingring 60 aligns with theopening 52. The retainingring 60 is sized to frictionally engage with the inside walls of opening 52 during insertion. Accordingly, the retaining ring may be roughly equal to or slightly larger in diameter Dr than the inside diameter D1 of opening 52. As shown, the left hand side of thebeveled edge 63 clears the opening inFIG. 3 so that the retainingring 60 may be passed through theopening 52. - In
FIG. 4 , thepivot rod 19 has been inserted such that the retainingring 60 has passed all the way through opening 52 and has “snapped” back to the left in the area shown incircle 76. Once the left edge of the retainingring 60 clears the end of theopening 52, thepivot rod 19 returns to its straight configuration. In this position, thebelt modules ring 60. - Turning to
FIG. 5 , an alternate embodiment of the modular belt of the present invention is shown. The overlappingarea 100 located between theoutermost link end 103 on thefirst belt module 104 and therod retaining ring 106 defines the locking behavior of the snap rod. The offset 107 between the pivotrod center axis 109 and thecentral axis 111 of opening 112 in theoutermost link end 103 for the retainingring 106 is a parameter that affects the locking behavior. This offset 107 can be increased by reducing the diameter D4 of therod 118 between thehead 121 and the retainingring 106. Theoutermost link end 103 has a recessedportion 122 that receives thehead 121. Theopening 112 in theoutermost link end 103 is larger than theopenings 127 in the plurality of link ends 130. - The
second belt module 133 also has anoutermost link end 136 having a recessedportion 139. The recessedportion 139 in thesecond belt module 133 receives the retainingring 106 when the first andsecond belt modules pivot rod 118. Theoutermost link end 136 on thesecond belt module 133 has a pivot rod opening 140 with adiameter 143 that is approximately equal to the diameter of theopenings 127 in thefirst belt module 104. - In
FIG. 6 , the offset 107 is shown from an end view of the intercalated belt modules. Thepivot rod axis 109 and thecentral axis 111 of theopening 112 are shown. - As shown in
FIG. 7 , thepivot rod 118 may be removed by use of ascrew driver 200. Thescrew driver 200 may be inserted under thehead 121 of thepivot rod 118 to provide leverage for bending therod 118 to align it with theopening 112 in theoutermost link end 103 in thefirst module 104. Once the retainingring 106 is aligned with theopening 112 thepivot rod 118 may be removed by sliding it outward in the direction indicated byarrow 203. - Turning to
FIG. 8 , an alternate embodiment of the present invention is shown. Abelt 300 is formed frommodules Link end 309 onmodule 306 has extra width to accommodate aninternal opening 315 for receiving retainingring 360 onpivot rod 319.Link end 312 onmodule 303 intercalates adjacent to linkend 309 as shown. Thelink end 309 also includes a recessedportion 318 for receivingend portion 346 ofpivot rod 319. -
Link end 309 also includes anopening 321 having the same diameter asopening 315.Openings ring 360. Thelink end 312 and the link ends disposed toward the middle of the belt have openings with a Diameter D2 that is smaller than D1. Thelongitudinal axis 325 ofopenings longitudinal axis 330 of the opening inlink end 312 and the openings toward the middle of the belt module. - Accordingly, during insertion of the
pivot rod 319, thepivot rod 319 has to be bent and once thering 360 clears theopening 315 it shifts to the left with respect toFIG. 8 such thatshoulder 375 engages the link surface aroundopening 315. - The embodiment of
FIG. 8 may also be provided with a pivot rod 118 (FIG. 5 ) having different diameters located above and below the retainingring 106. In the example shown, the diameter of the rod between the retaining ring and the head is smaller than the diameter of the rod between the retaining ring and the second end of the rod. - While the invention has been described in connection with certain embodiments, it is not intended to limit the scope of the invention to the particular forms set forth, but, on the contrary, it is intended to cover such alternatives, modifications, and equivalents as may be included within the spirit and scope of the invention as defined by the appended claims.
