专利汇可以提供Cup orienting and feeding device and method专利检索,专利查询,专利分析的服务。并且A cup orienting and feeding device is disclosed which employs a rotary conical feeder having a circular sidewall. The cups are engaged by a plow adjacent the periphery of the rotary feeder and delivered to a delivery chute and thereafter, in linear alignment with the delivery chute, is a tilting area in which the sidewalls flange outwardly and a ridge is provided in the base to tilt the cups in one direction or the other depending upon the orientation of the cup so that the open end is up. Thereafter the cups continue into a discharge chute which has an overlapping trap flange thus oriented in the open end up condition for delivery to automatic assembly equipment. The method recognizes that the center of gravity of a cup is closer to the top than it is to the open end and thus the tilting of the cup by engaging the skirt at a point closer between the open end than the top, but closer to the open end than the center of gravity, permits the cups to fall in the direction of the tops thus orienting them for delivery into the delivery chute.,下面是Cup orienting and feeding device and method专利的具体信息内容。

1. A cup feeding and orienting device for cups having a top, a skirt, and an open end comprising, in combination, a rotary feeder, tangential orienting means comprising a curved plow for rollingly presenting each cup within the rotary feeder to a discharge, a discharge chute for receiving the cups in rolling orientation with random open end and top orientation, tipping means for rollingly receiving the cups from the discharge chute having a width permitting the cups to tilt from their rolling orientation, pneumatic means for holding down and accelerating said cups positioned along the transition area from the discharge chute to the tipping means and aimed to engage a central portion of the skirt of the cups, ramp means positioned beneath the cups and within the tipping means for engaging the cup skirt at a point centrally of the cup''s center of gravity as the same proceeds through the tipping means thereby tipping the cups toward an open end up orientation, and a delivery chute confining the thus tipped cups in their open end up orientation.
2. In the cup feeding device of claim 1, said plow having a point oriented below the face of said conical rotary member, and a groove in said conical rotary member into which said plow point projects thereby presenting the upper portion of the plow to any cups passing by.
3. In the cup feeding device of claim 1, frame means, a tilt box within the frame means cradling the rotary feeder, and means for moving the tilt box to adjust the angle of the combined discharge chute, tipping means, and delivery chute.
4. In the cup feeding device of claim 1, said discharge chute, tilting means, and delivery chute having a common longitudinal axis lying in a plane parallel to the plane of rotation of the conical rotary member.
5. In the cup feeding device of claim 1, a deepened central portion of the bottom of said tipping means at the far end of the ramp means.
6. In the cup feeding device of claim 1, said tipping means comprising a track having walls which flare outwardly and then inwardly at the top thus permitting the cup top to tip over against the walls as it rolls down the ramp means.
7. In the cup feeding device of claim 1, a trap flange extending centrally of the upper portion of the side walls of the tipping means at a point near the end of the ramp means.
8. In the cup feeding device of claim 1, a ridge on said ramp means which becomes higher and then lower as the cup skirt rolls down the same and is tipped with the top toward the walls of the tipping means.
9. In the cup feeding device of claim 1, pneumatic means for holding down and accelerating said cups positioned along the transition area from the discharge chute to the tipping means and aimed to engage a central portion of the skirt of the cups.
10. In the cup feeding device of claim 1, pneumatic accelerating means directing an air jet against the cup oriented along the transition area from the tipping means to the delivery chute.
11. In the cup feeding device of claim 1, said rotary feeder having a central conical rotary member, and a circular side wall adjacent the periphery of said conical rotary member.
