Abstract
Abstract An article receiving and handling system includes a frame on which a conveyor belt is mounted to operate with the upper run of the conveyor belt disposed horizontally and traveling in one direction. Above the belt on the frame is a metering device including a rotor having spaced, radial vanes defining compartments and arranged to rotate about an axis parallel to the belt and extending in the same direction, the rotor being about as long as the upper run of the belt. On the belt are triggering devices spaced apart a predetermined distance and activating a responsive device on the frame to control the drive of the rotor. For each actuation, the rotor turns through a partial rotation to dump one compartment full of articles onto the belt. The articles, approximately of predetermined dimensions, are initially received in a hopper disposed above and converging downwardly toward the rotor. One of the hopper walls meets an arcuate housing concentric with the rotor and laterally enclosing but one of the compartments. The other hopper wall ends at a point approximately above the rotor axis and spaced above the rotor a distance equal to several times the predetermined article dimension. Articles resting on the rotor and extending up to the hopper have an unconfined side lying substantially at the natural angle of repose.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
182 words
An article receiving and handling system comprising: a. a frame; b. a conveyor belt on said frame; c. an article receiving hopper on said frame above said belt; d. a metering device interposed between said hopper and said belt, said metering device including a rotor having vanes dividing said rotor into compartments, and including an arcuate housing concentric with said rotor and having an arcuate extent to enclose only one of said compartments at a time; e. means for driving said metering device intermittently; f. means for advancing said belt; and, g. means dependent upon the relative advanced conveying position of said belt on said frame for controlling said driving means, said hopper being at least in part defined by a first wall extending to said rotor and by a second wall extending to and ending at a point above said rotor; an imaginary line from said point to the extremity of one of said vanes in a position remote from said first wall being substantially at the angle of repose of said articles in said hopper and resting on said rotor.
Claim 2
Dependent Claim
182 words
An article receiving and handling system comprising: a. a frame; b. a conveyor belt on said frame; c. an article receiving hopper on said frame above said belt; d. a metering device interposed between said hopper and said belt, said metering device including a rotor having vanes dividing said rotor into compartments, and including an arcuate housing concentric with said rotor and having an arcuate extent to enclose only one of said compartments at a time; e. means for driving said metering device intermittently; f. means for advancing said belt; and, g. means dependent upon the relative advanced conveying position of said belt on said frame for controlling said driving means, said hopper being at least in part defined by a first wall extending to said rotor and by a second wall extending to and ending at a point above said rotor; an imaginary line from said point to the extremity of one of said vanes in a position remote from said first wall being substantially at the angle of repose of said articles in said hopper and resting on said rotor.
Claim 3
Dependent Claim
28 words
A system as in claim 1 in which said articles have a predetermined dimension and said point is above said rotor a distance several times said predetermined dimension.
Claim 4
Dependent Claim
37 words
A system as in claim 1 including a triggering device on and traveling with said belt, means on said frame responsive to said triggering device, and means controlled by said responsive means for operating said driving means.
Claim 5
Dependent Claim
69 words
A system as in claim 1 in which said conveyor belt is disposed with an upper horizontal run, said metering device includes a rotor symmetrical about an axis parallel to and extending along said upper run, triggering devices are disposed on said belt at a predetermined distance apart, said rotor has a length of about said predetermined distance, and means responsive to said triggering devices control said driving means.
Claim 6
Dependent Claim
21 words
A system as in claim 1 including means for moving said second wall to shift said point relative to said rotor.
Claim 7
Dependent Claim
202 words
An article receiving and handling system comprising: a. a fRame; b. a conveyor belt on said frame; c. an article receiving hopper on said frame; d. a metering device interposed between said hopper and said belt, said metering device including a rotor having vanes dividing said rotor into compartments, said hopper being at least in part defined by a first wall extending into close juxtaposition to the extremity of the adjacent one of said vanes and by a second wall extending to and ending at a point above said rotor, an imaginary line from said point to the extremity of the next preceding one of said vanes in the direction of rotation of said rotor and remote from said first wall being substantially at the angle of repose of said articles in said hopper and resting on said rotor in the compartment defined by said one of said vanes and said next preceding one of said vanes; e. means for driving said metering device intermittently to advance only one of said compartments at a time; f. means for advancing said belt; and g. means dependent upon the relative advanced conveying position of said belt on said frame for controlling said driving means.
Claim 8
Dependent Claim
202 words
An article receiving and handling system comprising: a. a fRame; b. a conveyor belt on said frame; c. an article receiving hopper on said frame; d. a metering device interposed between said hopper and said belt, said metering device including a rotor having vanes dividing said rotor into compartments, said hopper being at least in part defined by a first wall extending into close juxtaposition to the extremity of the adjacent one of said vanes and by a second wall extending to and ending at a point above said rotor, an imaginary line from said point to the extremity of the next preceding one of said vanes in the direction of rotation of said rotor and remote from said first wall being substantially at the angle of repose of said articles in said hopper and resting on said rotor in the compartment defined by said one of said vanes and said next preceding one of said vanes; e. means for driving said metering device intermittently to advance only one of said compartments at a time; f. means for advancing said belt; and g. means dependent upon the relative advanced conveying position of said belt on said frame for controlling said driving means.
