Guard apparatus for a conveyor system
Various embodiments are directed to a guard apparatus for a conveyor system. The conveyor system comprises a plurality of rollers rotatably disposed between a pair of side frames of the conveyor system. The guard apparatus comprises a top cover and a first flange. The top cover is disposed in a first gap formed between a first roller and a second roller of the plurality of rollers. The first flange extends from a first end of the top cover into a second gap formed between a first end face of the first roller, a second end face of the second roller and a corresponding side frame of the conveyor system.
1 . A guard apparatus for a conveyor system comprising a plurality of rollers rotatably disposed between a pair of side frames thereof, the guard apparatus comprising:
a top cover disposed in a first gap formed between a first roller and a second roller of the plurality of rollers; and
a first flange extending from a first end of the top cover into a second gap formed between a first end face of the first roller, a second end face of the second roller and a corresponding side frame of the conveyor system.
2 . The guard apparatus of claim 1 , wherein the first flange comprises:
a central arm extending from the first end of the top cover;
a first arm extending from the central arm in a first direction; and
a second arm extending from the central arm in a second direction, wherein the first direction is opposite to the second direction.
3 . The guard apparatus of claim 2 , wherein the first arm extends into the second gap between the first end face of the first roller and the corresponding side frame of the conveyor system, and wherein the second arm extend into the second gap between the second end face of the second roller and the corresponding side frame of the conveyor system.
4 . The guard apparatus of claim 2 , wherein the central arm, the first arm and the second arm form a T-shape.
5 . The guard apparatus of claim 1 , wherein the first flange is configured to secure the top cover between the first roller and the second roller.
6 . The guard apparatus of claim 1 , further comprising a driving member configured to:
connect the first roller with the second roller; and
transmit motion from the first roller to the second roller.
7 . The guard apparatus of claim 6 , wherein a top surface of the top cover is disposed below the driving member.
8 . The guard apparatus of claim 6 , wherein the driving member is a rigid belt.
9 . The guard assembly of claim 1 , wherein each of a first edge and a second edge opposite to the first edge of the top cover is tapered to conform with the first roller and the second roller, respectively.
10 . The guard apparatus of claim 1 , wherein the top cover defines a plurality of friction-reducing features proximal to at least one roller of the conveyor system.
11 . The guard apparatus of claim 1 , further comprising:
a second flange extending from a second end of the top cover; and
at least one support rib extending between the first flange and the second flange.
12 . The guard apparatus of claim 11 , wherein the second flange is configured to extend into the first gap formed between the first roller and the second roller of the plurality of rollers.
13 . The guard apparatus of claim 11 , wherein the second flange comprises a first arcuate side and a second arcuate side, each of the first arcuate side and the second arcuate side conforming with first roller and the second roller, respectively.
14 . The guard apparatus of claim 11 , wherein a first length of the first flange is more than a second length of the second flange.
15 . The guard apparatus of claim 11 , wherein the top cover, the first flange and the second flange are formed integrally as a single component.
