Claims
- 1. In a conveyor system wherein articles are placed upon the article-conveyor run of a conveyor belt and are moved along a path which extends past a plurality of discharge stations at which the articles are selectively discharged from the conveyor, article-discharging means at one of said stations comprising a diverter which is adapted to be moved between a retracted position adjacent one edge of but outside said path of said belt and an extended position wherein it presents an article-diverting surface extending across said path substantially between the side edges of said belt at an angle to the direction of belt movement whereby articles being carried by the belt along said path are diverted by said diverter from said belt beyond the other edge of said path, mounting means for said diverter and providing support for said diverter when moving between said retracted position and said extended position with the movement being pivotal with respect to a vertical axis which is between said side edges of said belt and spaced from said one edge of said belt and remote from the downstream end of said diverter, wherein said axis is positioned transversely of said run of said belt with respect to the upstream end of said diverter, a pivot arm rigidly fixed to said diverter adjacent said upstream end, and which includes a vertical shaft extending upward from said pivot arm and providing mounting means therefor, a support arm for said shaft fixed to the other end thereof and extending horizontally to said pivotal axis above said article-conveyor run and pivot means mounted at said pivot axis and providing pivotal support for said pivot arm.
- 2. Apparatus as described in claim 1, wherein said axis is positioned transversely of said belt with respect to the upstream end of said diverter, and which includes a pivot arm rigidly fixed to said diverter adjacent said upstream end.
- 3. Apparatus as described in claim 2, wherein said arm extends at substantially right angles to said article-diverting surface of said diverter.
- 4. Apparatus as described in claim 1, which includes an electric motor having a vertical axis, a crank arm assembly operatively connected to said motor, and means mechanically connecting said crank arm assembly to said mounting means for said diverter to transmit reciprocating movement from said crank arm assembly to said diverter.
- 5. Apparatus as described in claim 4, wherein said motor and crank arm assembly are mounted beneath said conveyor run, and wherein said diverter is supported by means extending upwardly adjacent said one edge of said belt.
- 6. Apparatus as described in claim 4, which includes pivot means beneath said conveyor run and providing said pivot axis, and a pivot arm extending horizontally from said pivot means beyond said one edge of said belt.
- 7. Apparatus as described in claim 2, wherein said pivot arm extends horizontally from said diverter at an angle which is less than ninety degrees from said edge of said belt.
- 8. Apparatus as described in claim 7, wherein said pivotal axis is upstream with respect to the juncture of said diverter and said pivot arm.
- 9. Apparatus as described in claim 7 wherein said pivotal axis is downstream with respect to the juncture of said diverter and said pivot arm.
- 10. Apparatus as described in claim 1 wherein said shaft extends vertically from said diverter with the upper end of said shaft being fixed to said diverter and with the other end thereof being fixed to said support arm, said support arm being mounted to swing through an angle .alpha. during said pivotal movement of said diverter between an upstream position in which said diverter is in said retracted position, and a downstream position in which said diverter is in said extended position, and wherein said angle A is bisected by a vertical plane through said axis which is transverse to the direction of movement of said belt.
- 11. Apparatus as described in claim 1 wherein said support arm extends beyond said one edge of said path of said belt and wherein it swings from a position in which it extends from said axis toward said one edge of said belt and upstream with respect to the movement of said belt to a position wherein it extends at an angle which is downstream with respect to said movement.
