Conveyor sensor arrangement
A conveyor sensor arrangement is disclosed. The conveyor sensor arrangement includes a conveyor configured to move a product from a first conveyor end to a second conveyor end in a conveying direction. A plurality of fingers are pivotally arranged on a support that is positioned above the conveyor and that is arranged perpendicular to the conveying direction. Each finger of the plurality of fingers includes a first finger end and a second finger end, and the first finger end extends toward a surface of the conveyor. A single sensor is arranged above the conveyor. Contact between a leading edge of a product moving along the conveyor and at least one of the first finger ends causes a corresponding one of the second finger ends to trigger the sensor.
1. A conveyor sensor arrangement comprising:
a conveyor having a plurality of sections, each section of the plurality of sections configured to move a product from a first conveyor end to a second conveyor end in a conveying direction such that a product can proceed along the conveyor at a plurality of lateral positions upon the conveyor;
a plurality of fingers pivotally arranged on a support positioned above the conveyor and arranged perpendicular to the conveying direction, each said finger of the plurality of fingers includes a first finger end and a second finger end, the first finger ends extending toward a surface of the conveyor; and
a single sensor arranged above the conveyor, wherein contact between a leading edge of a product moving along the conveyor in any of the plurality of lateral positions upon the conveyor and at least one of the first finger ends causes a corresponding one of the second finger ends to trigger the single sensor.
2. The conveyor sensor arrangement of claim 1 , wherein the conveyor includes a plurality of conveying bands extending between the first conveyor end and the second conveyor end, and collectively establishing the plurality of lateral positions upon the conveyor the plurality of conveying bands defining a plurality of gaps therebetween, and each first finger end of the plurality of first fingers extend into a respective one of the plurality of gaps defined between adjacent conveying bands.
3. The conveyor sensor arrangement of claim 1 , wherein the second finger ends are enlarged compared to the first finger ends.
4. The conveyor sensor arrangement of claim 1 , wherein the single sensor is a break beam sensor, and the break beam sensor extends in a direction perpendicular to the conveying direction.
5. The conveyor sensor arrangement of claim 1 , wherein the plurality of fingers includes at least two fingers.
6. The conveyor sensor arrangement of claim 1 , wherein the plurality of fingers each move independently from one another.
7. The conveyor sensor arrangement of claim 1 , wherein the plurality of fingers are laterally spaced from each other along the support.
8. The conveyor sensor arrangement of claim 1 , wherein the support is a bar.
9. The conveyor sensor arrangement of claim 1 , wherein the support includes a frame with two mounting brackets, a crossbar extending between the two mounting brackets, and a pivoting bar on which the plurality of fingers are mounted.
10. The conveyor sensor arrangement of claim 9 , wherein the support includes a height adjustment mechanism to adjust a height of the crossbar, the pivoting bar, and the plurality of fingers relative to the surface of the conveyor.
