| An edge module for a modular plastic conveyor belt providing a self-closing retention system for retaining headless hinge rods in modular plastic conveyor belts. The edge module has a chamber in an outer edge portion of the module that slidably receives a rod retention member, such as a plug. The plug slides along the chamber from a closed position occluding a hinge rod passageway through interleaved hinges of consecutive rows of belt modules to an open, unoccluding position. A spring in the chamber urges the plug back toward the closed position. The plug is moved to the open position in two ways: by the force of a hinge rod against an oblique face during insertion of the rod into a belt; or manually by a tool engaging an easily accessible indentation in the plug. | ||||||

| 86 | Modular belt with tapered oblong hinge pins | US09701127 | 2000-11-21 | US06474464B1 | 2002-11-05 | Paul L. Horton; David W. Bogle; John C. Hawkins, Jr.; William R. Hartness, III; Mark W. Davidson |
| A modular conveyor belt (20) constructed of a series of rows (24, 25) of belt modules hingedly interlined by tapered oblong hinge pins (22) and suitable for following straight or curved conveyor paths. Aligned slots (30) formed in one set of hinge elements between successive rows are elongated in the direction of belt travel to allow the belt to fan out in turns. Fan-shaped apertures (38) formed in interleaved hinge elements of an adjacent row and aligned axially with the slots to admit a hinge pin (22) allow the belt to pivot at the hinge to articulate about a sprocket (181) or idler (186) or to enter and exit an incline. The oblong hinge pin has a first region at a first end (88) with a constant long axis to share the belt load among hinge elements encompassing the first region on straight runs. A second region of the hinge pin at an opposite second end (89) has a tapered oblong cross section, the long axis of which increases with distance from the second end to define a variable pitch and to spread the belt tension among the hinge elements at the outside of a turn encompassing the second region. Each belt row can be constructed of individual links stacked together on a support element (45) and retained by fasteners (52) or of integrally molded modules each comprising a transverse connecting member from which leading and trailing hinge elements extend. Accessory attachments, such as teeth (160) or sideguards (150), can be added to the belt. The belt can be driven by a cog, a roller chain, or other driving means driving lugs (172) extending from the bottom of the belt. The drive surfaces of the lugs can be obliquely arranged for better load sharing. | ||||||
| 87 | ROD RETENTION SYSTEM FOR MODULAR PLASTIC CONVEYOR BELT | US09185230 | 1998-11-03 | US20010042677A1 | 2001-11-22 | ERIC K. PALMAER |
| Rod retention systems are disclosed for modular plastic conveyor belts. In one embodiment the connecting rods, which pass through interdigited link ends of successive modules, each include a circumferential groove at one location, receiving a retaining clip at a position between adjacent interdigited link ends, snapped into position in the groove. The retaining clip provides easy assembly using existing tools, and a rod can easily be removed from the belt by applying sharp force on the end of the rod. In a second embodiment a rod retention system has blocking members at both ends of each module row, forming edges of the belt. A space about two or three link ends wide extends laterally from the blocking member to the first rod-encircling link end inboard of the blocking member; within the space the module is devoid of link end structure which would confine the rod from the bottom of the belt. The rod is forced into a bending configuration for insertion and removal from the bottom of the belt, and assumes a substantially straightened, normal configuration after insertion. In another embodiment the belt has an opening at the location of the blocking structure, aligned with the series of link end openings, but the rod end is preformed in a bent configuration. In a further embodiment the rods each have heads on one end, and the heads reside inboard of the blocking structure in the assembled belt. | ||||||

| A number of link plates molded of synthetic resin are pivotally connected together by connecting pins to form a molded conveyor particularly suitable for the conveyance of delicate or easy-to-break articles. Each link plate has a plurality of aligned bush holes formed at intervals along a trailing end edge of the link plate, and a plurality of aligned pin holes formed at intervals along a leading end edge of the link plate. Each of the connecting pins is inserted alternately into the pin holes in one link plate and the bush holes in the adjacent link plate to pivotally connect these two link plates. A locking projection formed on the connecting pin to lock the connecting pin in position against detachment is located closer to one end of said connecting pin than to a longitudinal central portion of said connecting pin. The locking projection thus arranged reduces a stroke of hammering required to drive the connecting pin into the pin and bush holes. The connecting pin further has a flange-like stopper serving to position the locking projection within one of the bush holes when the connecting pin is in its fully inserted position. | ||||||

| 91 | Shuttle plugs for retaining headless pivot rods in conveyor belts | US708753 | 1996-09-05 | US5904241A | 1999-05-18 | Christopher J. Verdigets; James O. Gundlach |
| A modular link of a conveyor belt is provided with belt edge structure for retaining in the belt so that it may not escape or protrude from a belt edge a headless pivot rod journalled in apertures in interdigitated link ends interconnecting adjacent links. The retention structure provides a shuttling plug movable into two bistable positions within a mating shuttle cavity having an open end and a blind end. The cavity extends transversely in the link between two link end pivot rod journalling apertures to intersect only one journalling aperture. The two bistable states for the shuttle plug respectively (1) lock the headless pivot rod in place in a stable pivot rod occluding position extending into said journalling aperture, and (2) permits the headless pivot rod to enter or leave the journalled position by movement of the shuttle plug out of the occluding position into a second stable position. The belt edge structure provides an adjoining link with a cavity closure surface which confines the open end of the mating shuttle cavity to occlude movement of the plug out of the mating shuttle cavity when the conveyor belt is operating. | ||||||
| 92 | Conveyor belt assembly with headed retention shaft | US755599 | 1996-11-25 | US5826705A | 1998-10-27 | Earl A. Ramsey; Jeffrey E. DeLair |
| The conveyor belt assembly includes links having forward and rearwardly laterally spaced projections with forward and rearward projections of adjacent links being interdigitated and coupled to one another by a shaft passing through the aligned openings of the link projections. The shaft includes a headed end having two retainer sections with projections extending in diametrically opposite directions outside of the peripheral confines of the shaft. Diametrically opposite inset portions at axially spaced locations are also provided. By inserting the non-headed end of the shaft through the aligned openings and pressing the headed end through the first opening, the headed end is deformed laterally, first in one direction and then in an opposite direction, in order to pass through the end opening into a lock cavity. The projections prevent axial movement of the shaft in respective opposite directions. | ||||||

| An improved adjustable conveyor belt has a plurality of modules having intermeshing link ends extending lengthwise. The modules are connected together by connecting pins extending widthwise through holes formed in the link ends. Each of the modules also has side edges and a slot adjacent to each of its side edges. Thus, slots are provided along the side edges of the belt regardless of the arrangement of the modules. A stop, removably fitted into slots located along the side edges of the belt, prevents widthwise movement of the connecting pins. The stop has a guide mechanism for guiding the stop into the slot, an end portion which extends into the pin insertion hole, an engaging portion which engages a tongue formed in the slot, and a protrusion which snaps into the pin insertion hole. This configuration makes it easy to assemble, add to, and dismantle the conveyor belt, without substantially increasing the size or weight of the assembly. | ||||||
