专利汇可以提供Centrifugal parts feeder and method专利检索,专利查询,专利分析的服务。并且A centrifugal parts feeder having a conical central driven rotor surrounded by a circular bowl wall. Tooling is provided for the feeding of cylindrical parts particularly where the length exceeds the diameter. A bowl plow spaced from the bowl wall at a distance slightly greater than the diameter of the parts accomplishes the first alignment and then delivers the parts to an elevating plow and thereafter to a corner trap which diagonally engages the vertically oriented cylindrical parts and delivers the same to a reject discharge where the horizontal parts are dropped and recirculated. A turning chute is optionally provided where the parts are to be delivered with the axis horizontally oriented. A trip finger is provided at a point downstream from the bowl plow to orient parts which are tipped. The method contemplates the steps of confining the cylindrical parts for single file movement, positively confining the parts to be delivered, elevating the same, and then rejecting those parts which are not elevated and confined.,下面是Centrifugal parts feeder and method专利的具体信息内容。

1. A feeder for cylindrical parts comprising, in combination, a rotary conical drive member, a peripheral circular bowl wall surrounding said conical member to confiNe circulating parts, a bowl plow having a tapered end close to said rotary member spaced from said wall and concentric therewith for a sector of said wall at a spacing in excess of the diameter of a cylindrical part, an elevating plow adjacent said wall and downstream of said bowl plow tapered end and having a rail face to support and elevate a portion of a cylindrical part, a corner trap above and diagonally opposed to said elevating plow for engaging a portion of said cylindrical parts when the cylindrical axis is substantially parallel to the axis of rotation of the conical member, said bowl plow terminating at a point before the termination of the corner trap and elevating plow thereby defining a reject discharge for the cylindrical parts which are not oriented with their axis parallel with the axis of rotation of the conical member and diagonally retained by the elevating plow and corner trap.
2. In the feeder of claim 1, a trip finger positioned along the forward portion of the bowl plow to catch angled parts and deflect the same to a vertical orientation.
3. In the feeder of claim 2, a pile up tongue forward of the corner trap at an elevation above the top of a vertically oriented part.
4. In the feeder of claim 3, a pneumatic assist pile up remover above the top of a vertical part at a mid-point along the elevating plow.
5. In the feeder of claim 4, a pneumatic assist directed across the reject discharge above the mid point of a horizontally aligned part to assist in the discharge of the same.
6. In the feeder of claim 5, a turning chute for receiving said oriented parts to turn same 90* to a rolling orientation.
7. In the feeder of claim 6, a turning finger extension of said corner trap to deliver the parts to the turning chute.
8. In the feeder of claim 1, a pile of tongue forward of the corner trap at an elevation above the top of a vertically oriented part.
9. In the feeder of claim 1, a turning chute for receiving said oriented parts to turn the same 90* to a rolling orientation.
10. In the feeder of claim 1, a pneumatic assist directed across the reject discharge above the midpoint of a horizontally aligned part to assist in the discharge of the same.
11. In the feeder of claim 9, a turning finger extension of said corner trap to deliver the parts to the turning chute.
12. A method for feeding cylindrical parts comprising the steps of confining the cylindrical parts for single file movement, positioning all parts with the cylindrical axes either along the flow path or perpendicular thereto, elevating all parts whereby the parts with their axis perpendicular to the flow path rise above the parts with their axes parallel to the flow path, confining the higher parts diagonally across their corners, rejecting the parts with their axes parallel to the flow path by supporting at an unstable location away from the effective center of gravity thereby permitting the same to fall away while the other parts remain.
