Conveyor assembly

Claim 2

A conveyor assembly for articulated link conveyor, comprising: a stationary frame; an elongated guide ramp securely supported by said frame for guiding conveyor links of a slat type on an upper flight track of the conveyor assembly, said guide ramp having a generally horizontal leading section and a downwardly inclined trailing section, said guide ramp comprising: (a) an opposed pair of outer plates, each outer plate having a first horizontal side and a second side bent at substantially 90° wherein each second side is securely attached to a respective sidewall of said frame; (b) an opposed pair of central plates, each central plate having a first and a second side, said first side adjustably attached to the first side of an associated outer plate; and (c) an opposed pair of wear strips, each wear strip attached to the second side of the associated central plate whereby a clearance provided between said wear strips provides a guide path for said conveyor links; a sprocket mounted on said frame for driving the conveyor links, said sprocket having teeth such that the uppermost position of said teeth are at a location substantially lower than the horizontal surface of said leading section; a drive mechanism providing drive means for said sprocket; and protective and supporting means operably associatable with said guide ramp for preventing items being transported on the conveyor links from falling into said drive mechanism and for protecting the operator's hands and fingers.

Claim 3

The conveyor assembly as defined in claim 1, wherein the protective and supportive means includes a coverplate substantially on the same plane as the links being horizontally guided by the leading section of the guide ramp, said coverplate supported by the frame and separated from the conveyor links by a small clearance, at a point where the leading section meets the trailing section, so that when items descend from the horizontal leading section they are urged onto said coverplate.

Claim 4

The conveyor assembly as defined in claim 2, wherein each of said central plates includes a plurality of lateral slots for insertion of bolts for adjustably mounting each central plate to its associated outer plate.

Claim 5

The conveyor assembly as defined in claim 3, wherein said wear strips are of rectangular cross section and formed of ultra high molecular weight linear polypropylene.

Claim 6

The conveyor assembly as defined in claim 4, wherein the trailing section of said guide ramp is inclined downwardly approximately 15° from said horizontal leading section.

Claim 7

A conveyor assembly for articulated link conveyor, of the type having individual links with downwardly extending opposed feet, comprising: a stationary frame having substantially vertical side walls; an elongated guide ramp securely supported by said frame for guiding the links on an upper flight track of the conveyor assembly, said guide ramp comprising: (a) a pair of opposed laterally spaced elongated outer plates, each plate having a bend along its entire length such that one side of each outer plate fits essentially flush against a side wall of the frame and is mounted to said side wall, and a second side of each outer plate projects inwardly toward the opposing outer plate; (b) a pair of opposed laterally spaced elongated central plates, each plate of essentially the same length of the outer plates and each central plate adjustably mounted to said inwardly projecting second side of an associated outer plate such that each central plate projects inwardly toward the opposing central plate; (c) a pair of opposed laterally spaced elongated wear strips, each wear strip of essentially the same length of the central plates, and each wear strip securely attached to an associated central plate such that each wear strip projects inwardly toward the opposing wear strip whereby an appropriate clearance is provided between said opposing wear strips to provide a guide path for said links; and whereby each plate and wear strip has a horizontal leading section and a downwardly inclined trailing section; and protective and supportive means operably associatable with said guide ramp for preventing items being transported on said links from falling into a drive mechanism and for protecting the operator's hands and fingers, said protective and supportive means including a coverplate substantially on the same plane as the links being horizontally guided by the leading section of the guide ramp, said coverplate supported by the frame and separated from the conveyor links by a small clearance, at a point where the leading section meets the trailing section, so that when items descend from the horizontal leading section they are urged onto said coverplate.

Claim 8

A conveyor assembly for articulated link conveyor, of the type having individual links with downwardly extending opposed feet, comprising: a stationary frame having substantially vertical side walls; an elongated guide ramp securely supported by said frame for guiding the links on an upper flight track of the conveyor assembly, said guide ramp comprising: (a) a pair of opposed laterally spaced elongated outer plates, each plate having a bend along its entire length such that one side of each outer plate fits essentially flush against a side wall of the frame and is mounted to said side wall, and a second side of each outer plate projects inwardly toward the opposing outer plate; (b) a pair of opposed laterally spaced elongated central plates, each plate of essentially the same length of the outer plates and each central plate adjustably mounted to said inwardly projecting second side of an associated outer plate such that each central plate projects inwardly toward the opposing central plate; (c) a pair of opposed laterally spaced elongated wear strips, each wear strip of essentially the same length of the central plates, and each wear strip securely attached to an associated central plate such that each wear strip projects inwardly toward the opposing wear strip whereby an appropriate clearance is provided between said opposing wear strips to provide a guide path for said links; and whereby each plate and wear strip has a horizontal leading section and a downwardly inclined trailing section; and protective and supportive means operably associatable with said guide ramp for preventing items being transported on said links from falling into a drive mechanism and for protecting the operator's hands and fingers, said protective and supportive means including a coverplate substantially on the same plane as the links being horizontally guided by the leading section of the guide ramp, said coverplate supported by the frame and separated from the conveyor links by a small clearance, at a point where the leading section meets the trailing section, so that when items descend from the horizontal leading section they are urged onto said coverplate.

Claim 9

The conveyor assembly as defined in claim 6, wherein each of said central plates includes a plurality of lateral slots for insertion of bolts for adjustably mounting each central plate to its associated outer plate.

Claim 10

The conveyor assembly as defined in claim 7, wherein said wear strips are of rectangular cross section and formed of ultrahigh molecular weight linear polypropylene.

Claim 11

The conveyor assembly as defined in claim 8, wherein said drive mechanism includes a motor beneath a sprocket, which drives said links, driving said sprocket by a means of a drive train.
