Abstract

The belt edge of a belt conveyor may wander off-line and foul a conveyor stool leg 10, thereby causing damage to the edge of the belt 3. In order to reduce the amount of such damage a belt-edge deflector 1 is 2 closely-associated with the end-portion of a conveyor roller 2 and separates that end portion from a stool leg. The surface of the defector onto which part of the belt can move when running off-line is so curved that the rigidity of that part of the belt is reduced below that rigidity which it had when flat and on-line. <IMAGE>

Description

SPECIFICATION Belt conveyor This invention relates to belt conveyors.
A considerable amount of damage occurs to the belts of conveyors when, for some reason or other, the belt wanders off-line and, in a horizontal flat attitude, fouls the stool legs. This fouling is largely confined to the return run of the conveyor.
It is an object of this invention to reduce the amount of damage which occurs to such a belt when it wanders off-line.
According to this invention there is provided a belt-edge deflector which, in use, is closely-associated with an end-portion of a conveyor roller and which has a surface so shaped that, if a belt wanders off-line onto that surface, the part of the belt on the surface is no longer flat and its rigidity, as a consequence, is reduced.
The belt-edge deflector may be made from polypropylene.
There is also provided by this invention a belt conveyor having associated with each end of some, at least, of its rollers, a belt-edge deflector in accordance with the invention.
A belt-edge deflector in accordance with one em bodiment of the invention is illustrated in the accompanying drawings of which Figure 1 is a view of the belt-edge deflector (in section) and an end-portion of an associated conveyor belt roller, Figure 2 is a section taken along the line ll-ll of Figure 1, and Figure 3 is a section taken along the line Ill-Ill of Figure 1.
Referring to the drawings, the belt-edge deflector 1 is associated with an end-portion of a conveyor belt roller 2 over which passes a conveyor belt 3.
The roller 2 has a spindle 4 supported in a bracket 5. The part of the belt on the roller 2, when the belt is running true or on-line, is flat.
The belt-edge deflector comprises a body portion 6 having two bifurcations 7, only one of which is visible in the drawings. The body portion 6 also has two pairs of legs 8, 8' and 9, 9' which straddle an appropriately-flattened part of the spindle 4.
The part of the body portion 6 between the two pairs of legs rests on the upper surface of the bracket 5.
The upper surface of the body portion is concave (as seen in Figure 1) and merges smoothly into the upper surfaces of the two bifurcations 7; at right angles thereto the surface is convex (see Figure 2).
When the belt-edge deflector 1 is supported by the spindle 4 and the bracket 5, it is closely-adjacent to the end-portion of the roller 2. One of the bifurcations 7 is disposed on one side of the roller and the other of the bifurcations is disposed on the other side of the roller. The free ends of the bifurcations are located at about one-quarter of the roller diameter below the upper edge of the roller.
The outermost edge of the body portion 1 terminates close to a stool leg 10. Thus the belt-edge deflector lies between the end of the roller and the stool leg.
In use, such a belt-edge deflector will be associated with each end-portion of a roller in a region of the conveyor where the belt is likely to wander offline. If the belt tends to wander off-line, a part will pass onto the concavo-convex surface of the beltedge deflector.
As a consequence that part of the belt will no longer be flat and its rigidity will be lower than the rigidity which it had when running flat and on-line.
Because of such reduction in its rigidity, the belt edge is less likely to suffer damage should it wander sufficiently off-line for the edge to foul a stool leg.
1. A belt-edge deflector which, in use, is closely-associated with an end-portion of a conveyor roller and which has a surface so shaped that, if a belt wanders off-line onto that surface, the part of the belt on the surface is no longer flat and its rigidity, as a consequence, is reduced.
2. A belt-edge deflector as claimed in Claim 1 in which the belt-engageable surface is concavo-convex.
3. A belt-edge deflector as claimed in Claim 1 or in Claim 2 which is made from polypropylene.
4. A belt conveyor having associated with each end of some, at least, of its rollers, a belt-edge deflector as claimed in any one of Claims 1 to 3.
5. A belt-edge deflector sector substantially as hereinbefore described and as illustrated in the accompanying drawings.
6. A belt conveyor having a belt-edge deflector substantially as hereinbefore described and as illustrated in the accompanying drawings.
