Abstract

Abstract A method for distributing objects or goods among a number of consecutively placed points of consumption or storage from a conveyor which is composed of several consecutively arranged belt, chain, rope or other conveyors on which the objects or goods have been arranged to be transported from one conveyor to the other and to be distributed among the points of consumption or storage through the spaces between conveyors. The invention is characterized in that the gaps between the conveyors are constantly kept open and filled with the material itself which is being handled.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 218 words
Apparatus for grinding logs, said apparatus comprising a plurality of horizontally disposed conveyors at substantially the same elevation, said conveyors being consecutively spaced from one another in the direction of conveyor feed, channel means defining a substantially vertical channel between successive spaced conveyors for receiving logs conveyed by said conveyors to contain the logs in a pile, grinding means at the bottom of each channel for grinding the logs conveyed into said channel means, said conveyors being operatively associated with said channel means and the piles of logs therein to form a continuous stream of logs extending from one conveyor to the next adjacent conveyor over the pile of logs disposed in the intermediate channel, said conveyors each comprising an endless belt, and a pair of spaced rollers for driving each said belt, belt drive units for driving said belts in either direction, said belts being spaced at a fixed distance from one another, the width of said channel means being substantially greater than the diameter of the logs such that at least two logs are contained in said channel means in a horizontal disposition at substantially the same elevation while the logs are stacked on the conveyors in irregular fashion, and a fixed end wall at the last channel means to block advance of the logs therebeyond.
Claim 2
Dependent Claim 218 words
Apparatus for grinding logs, said apparatus comprising a plurality of horizontally disposed conveyors at substantially the same elevation, said conveyors being consecutively spaced from one another in the direction of conveyor feed, channel means defining a substantially vertical channel between successive spaced conveyors for receiving logs conveyed by said conveyors to contain the logs in a pile, grinding means at the bottom of each channel for grinding the logs conveyed into said channel means, said conveyors being operatively associated with said channel means and the piles of logs therein to form a continuous stream of logs extending from one conveyor to the next adjacent conveyor over the pile of logs disposed in the intermediate channel, said conveyors each comprising an endless belt, and a pair of spaced rollers for driving each said belt, belt drive units for driving said belts in either direction, said belts being spaced at a fixed distance from one another, the width of said channel means being substantially greater than the diameter of the logs such that at least two logs are contained in said channel means in a horizontal disposition at substantially the same elevation while the logs are stacked on the conveyors in irregular fashion, and a fixed end wall at the last channel means to block advance of the logs therebeyond.
Claim 3
Dependent Claim 26 words
Apparatus as claimed in claim 1, wherein said vertical channel is open at the upper end thereof and communicates directly with the space between adjacent conveyors.
Claim 4
Dependent Claim 21 words
Apparatus as claimed in claim 2 wherein said conveyors occupy fixed positions above said grinding means in a common horizontal plane.
