Abstract
Abstract A method and an apparatus for sorting fruits, vegetables or the like by weight. An electronic weighing device is used in combination with a basket conveyer system arranged by mounting evenly spaced receiving or weighing baskets on a chain conveyer. The basket are loosely mounted on the mounting metal members of the chain conveyer. Each time a basket is conveyed over a weighing stand of the weighing device, the basket is detached from the mounting member and is pushed so as to slide over a measuring rail by a freely rotatable pushing member which has small frictional resistance and is arranged to be in pushing contact with a vertical face of the basket.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
171 words
In an apparatus for sorting articles by weight, in which an article to be sorted is transported longitudinally in a basket along a chain conveyor to a weighing device for weighing the basket and article therein, the improvement wherein: the conveyor includes a mounting member fixed thereto and longitudinally movable therewith for attachment to said basket; said basket being loosely disengagably mountable on said mounting member so as to be vertically and longitudinally movable with respect thereto, said basket having a lower surface and a vertical abutting face; a rotatable pushing member mounted for longitudinal movement with said chain conveyor, abutting said vertical face for pushing said basket longitudinally along said conveyor; a weighing device disposed along said conveyor, for weighing said basket and the article therein, including a rail having means for slidably engaging said lower surface to raise said basket and concurrently disengaging said basket from said mounting member, without separating said pushing member from said vertical face, said basket being slidable onto said rail along said lower surface.
Claim 2
Dependent Claim
171 words
In an apparatus for sorting articles by weight, in which an article to be sorted is transported longitudinally in a basket along a chain conveyor to a weighing device for weighing the basket and article therein, the improvement wherein: the conveyor includes a mounting member fixed thereto and longitudinally movable therewith for attachment to said basket; said basket being loosely disengagably mountable on said mounting member so as to be vertically and longitudinally movable with respect thereto, said basket having a lower surface and a vertical abutting face; a rotatable pushing member mounted for longitudinal movement with said chain conveyor, abutting said vertical face for pushing said basket longitudinally along said conveyor; a weighing device disposed along said conveyor, for weighing said basket and the article therein, including a rail having means for slidably engaging said lower surface to raise said basket and concurrently disengaging said basket from said mounting member, without separating said pushing member from said vertical face, said basket being slidable onto said rail along said lower surface.
Claim 3
Dependent Claim
22 words
The improvement as in claim 1, wherein said apparatus includes a plurality of baskets and corresponding mounting members disposed along said conveyor.
Claim 4
Dependent Claim
64 words
The improvement as in claim 1, wherein said basket comprises spaced opposing sidewalls having spaced opposing openings therein, said mounting member comprises a shaft extending through said opposing openings so as to be engagable with the edges of said openings and being vertically and longitudinally movable therein, said means for slidably engaging said lower surface comprising means for disengaging said edges from said shaft.
Claim 5
Dependent Claim
74 words
The improvement as in claim 3, wherein said engaging means comprises a measuring rail and two guide rails located on longitudinally opposite sides of said measuring rail, said measuring rail being vertically movable relative to said two guide rails, said guide rails including ramps for respectively slidably raising and lowering said basket onto and from said measuring rail and respectively concurrently disengaging and engaging said shaft from and with said edges of said openings.
Claim 6
Dependent Claim
73 words
The improvement as in claim 1, wherein said engaging means comprises a measuring rail and two guide rails located on longitudinally opposite sides of said measuring rail, said measuring rail being vertically movable relative to said two guide rails, said two guide rails including ramps for respectively slidably raising and lowering said basket onto and from said measuring rail and respectively concurrently disengaging and engaging said basket from and with said mounting member.
Claim 7
Dependent Claim
171 words
In a method of sorting articles by weight in which an article to be weighed is transported longitudinally in a basket by a chain conveyor and slid onto and off of a weighing device along the conveyor for weighing the basket and article therein, the improvement wherein said method includes the steps of: (1) loosely mounting the basket on a mounting member of a chain conveyor for longitudinal movement therewith with the mounting member in contact therewith, (2) pushing the basket longitudinally at a vertical face thereof with a rotatable pushing member abutting the vertical surface, (3) measuring the weight of the article and the basket while pushing the basket with the pushing member such that the basket slides over a measuring rail over a weighing stand of the weighing device, (4) disengaging the mounting members form the basket so that the basket is disengaged from the mounting member and moved only by the pushing member during said measuring step; and (5) sorting the article by weight after said measuring step.
Claim 8
Dependent Claim
171 words
In a method of sorting articles by weight in which an article to be weighed is transported longitudinally in a basket by a chain conveyor and slid onto and off of a weighing device along the conveyor for weighing the basket and article therein, the improvement wherein said method includes the steps of: (1) loosely mounting the basket on a mounting member of a chain conveyor for longitudinal movement therewith with the mounting member in contact therewith, (2) pushing the basket longitudinally at a vertical face thereof with a rotatable pushing member abutting the vertical surface, (3) measuring the weight of the article and the basket while pushing the basket with the pushing member such that the basket slides over a measuring rail over a weighing stand of the weighing device, (4) disengaging the mounting members form the basket so that the basket is disengaged from the mounting member and moved only by the pushing member during said measuring step; and (5) sorting the article by weight after said measuring step.
Claim 9
Dependent Claim
22 words
The improvement as in claim 6, further including the step of reengaging the basket with the mounting member after said measuring step.
Claim 10
Dependent Claim
67 words
The improvement as in claim 7, wherein the step of disengaging includes the step of slidingly raising the basket on a first guide rail located along the conveyor on one longitudinal side of the measuring rail, and the step of reengaging includes the step of slidingly lowering the basket on a second guide rail located along the conveyor on the other longitudinal side of the measuring rail.
