Abstract
Abstract A conveyor system primarily for use in automatic sorting systems in which it is desired to transfer articles from a number of feeding stations to a common sorting conveyor with a well-defined transfer time, said conveyor system comprising at least a first and a second conveyor, a partial length of said first conveyor extending closely along a partial length of said second conveyor substantially parallely therewith, said conveyors being driven at equal velocities, and transfer means participating in the movement of the conveyors at least along said partial length and operable to laterally deplace an article from one of said conveyors to the other of said conveyors by a movement substantially perpendicular to the moving direction of the conveyors along said partial lengths thereof.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
198 words
An article sorter conveyor system comprising at least two conveyors of which at least one is a sorting conveyor provided with diverter means located at several places along said sorting conveyor and being operable to divert articles from said sorting conveyor in response to actuator means therefor being selectively operated, the other of said conveyors having a partial length thereof extending closely along a partial length of said sorting conveyor substantially parallel therewith, said conveyors being driven at equal velocities, article transfer means being provided adjacent said partial lengths and being operable to participate in the movement of the conveyors and to deplace articles from one conveyor to the other by a movement substantially perpendicular to the moving direction of the conveyors, said system including destination code register means operable to receive a destination code for each article fed to the first of said conveyors as seen in the direction of movement thereof, to advance said destination code in synchronism with the movement of the conveyors, and to operate said actuator means at a selected position along the sorting conveyor in response to the code of the article being advanced to a corresponding stage in said register means.
Claim 2
Dependent Claim
198 words
An article sorter conveyor system comprising at least two conveyors of which at least one is a sorting conveyor provided with diverter means located at several places along said sorting conveyor and being operable to divert articles from said sorting conveyor in response to actuator means therefor being selectively operated, the other of said conveyors having a partial length thereof extending closely along a partial length of said sorting conveyor substantially parallel therewith, said conveyors being driven at equal velocities, article transfer means being provided adjacent said partial lengths and being operable to participate in the movement of the conveyors and to deplace articles from one conveyor to the other by a movement substantially perpendicular to the moving direction of the conveyors, said system including destination code register means operable to receive a destination code for each article fed to the first of said conveyors as seen in the direction of movement thereof, to advance said destination code in synchronism with the movement of the conveyors, and to operate said actuator means at a selected position along the sorting conveyor in response to the code of the article being advanced to a corresponding stage in said register means.
Claim 3
Dependent Claim
23 words
A sorter conveyor system as claimed in claim 1, in which said diverter means and said article transfer means are of uniform design.
Claim 4
Dependent Claim
74 words
A sorter conveyor system as claimed in claim 1, in which one of said conveyors is a first feeding conveyor operable to receive articles fed thereto from a feeding station and to advance said articles to a transfer station adjacent said partial length of the conveyor, said transfer station having permanently operative actuator means for said article transfer means whereby all articles advanced to said transfer station are automatically transferred to said sorting conveyor.
Claim 5
Dependent Claim
32 words
A sorter conveyor system as claimed in claim 3, in which there is provided at least one additional feeding conveyor operable to convey articles to another transfer station adjacent said sorter conveyor.
Claim 6
Dependent Claim
87 words
A sorter conveyor system as claimed in claim 3, in which there is provided at least one further feeding conveyor operable to receive articles fed thereto from a further feeding station and to convey these articles to a further transfer station located adjacent said first feeding conveyor and having permanently operative actuator means for said article transfer means of said further feeding conveyor whereby all articles advanced to said further transfer station are automatically transferred to said first feeding conveyor and therefrom further to said sorting conveyor.
Claim 7
Dependent Claim
20 words
A sorter conveyor system as claimed in claim 1, in which said at least two conveyors comprise two sorting conveyors.
Claim 8
Dependent Claim
45 words
A sorter conveyor system as claimed in claim 1, in which at least a first conveyor is of the laterally tiltable slat-belt type and said partial length thereof is located in a level higher than that of the said partial length of a second conveyor.
Claim 9
Dependent Claim
63 words
A sorter conveyor system as claimed in claim 1, in which the conveyors are of the endless-belt type each passing around sprockets at the ends thereof and having an upper run and a lower run, said sprockets having their axes mutually inclined so as to provide for said upper runs running closely together and said lower runs being spaced laterally from each other.
Claim 10
Dependent Claim
109 words
A sorter conveyor system as claimed in claim 8, in which one of the conveyors is of the laterally tiltable slat-belt type, having a lower run located underneath and laterally offset from an upper run, and further having slat tilting conTrol means for controlling the lateral angular position of said slats at any place along the upper run, said tilting control means being operable to maintain said slats in a substantially horizontal position until the slats successively reach a position in which they are caused to respectively tilt in response to the operation of said actuator means upon reaching stationary means for effecting slat tilting for article transfer purposes.
