SECTION B – PERFORMING OPERATIONS; TRANSPORTING

B 07

SEPARATING SOLIDS FROM SOLIDS; SORTING (separation in general B01D; wet separating processes, sorting by processes using fluent material in the same way as liquid B03; using liquids B03B, B03D; sorting by magnetic or electrostatic separation of solid materials from solid materials or fluids, separation by high voltage electric fields B03C; centrifuges or vortex apparatus for carrying out physical processes B04; sorting peculiar to particular materials or articles and provided for in other classes, see the relevant classes)

B 07 C

POSTAL SORTING; SORTING INDIVIDUAL ARTICLES, OR BULK MATERIAL FIT TO BE SORTED PIECE-MEAL, e.g. BY PICKING (specially adapted for a specific purpose covered by another class, see the relevant place, e.g. A43D 33/06, B23Q 7/12)

Note

This subclass covers sorting of materials or articles by hand or by devices actuated, manually or automatically, as a result of inspection or of detection or measurement of some feature of the material or articles.

Subclass Index

SORTING CHARACTERISED BY THE METHOD

B07C 5/00, B07C 7/00, B07C 9/00

SORTING ACCORDING TO DESTINATION

B07C 1/00, B07C 3/00

Postal sorting; Similar sorting of documents, e.g. cheques (tube mail systems B65G 51/04; sorting information records, e.g. punched cards, G06F 7/10)

Measures preceding sorting according to destination

Forming articles into a stream; Arranging articles in a stream, e.g. spacing, orientating

Forming a stream from a bulk; Regulating the stream, e.g. spacing the articles

Orientating; Aligning

Sorting according to size or flexibility

Separating letters from parcels

Sorting according to length or width

Sorting according to thickness or stiffness

Orientating articles other than in a stream

Sorting according to orientation, e.g. according to position of stamp

Sorting according to destination

Apparatus characterised by the means used for distribution

Drum-type sorting machines

Linear sorting machines in which articles are removed from a stream at selected points

using arrangements of conveyers

Apparatus characterised by the means used for detection of the destination (methods or arrangements for reading and recognising printed or written characters or geometric figures G06K 9/00)

using electric or electronic detecting means (B07C 3/14 takes precedence)

using light-responsive detecting means

using magnetic detecting means

Devices or arrangements for indicating destination, e.g. by code marks

Arrangements for facilitating the visual reading of addresses, e.g. display arrangements

Sorting according to a characteristic or feature of the articles or material being sorted, e.g. by control effected by devices which detect or measure such characteristic or feature; Sorting by manually actuated devices, e.g. switches (sorting by hand only B07C 7/00; separating solids from solids by sieving, screening, or sifting or by using gas currents or other separating by dry methods applicable to bulk material B07B; sorting of coins G07D) [3]

Measures preceding sorting, e.g. arranging articles in a stream, orientating

Sorting according to size

measured mechanically

by calipering using relatively moving article-engaging means, e.g. clamps [2]

measured electrically or electronically (B07C 5/10 takes precedence)

measured by light-responsive means

characterised by the application to particular articles, not otherwise provided for (sorting eggs A01K 43/00)

Sorting timber or logs

Sorting according to weight (sorting eggs A01K 43/00; weighing apparatus per se G01G)

using a single stationary weighing mechanism

for separating articles of less than a predetermined weight from those of more than that weight

using a plurality of stationary weighing mechanisms

using moving weighing mechanisms, e.g. moving along a circular path

wherein the counterbalancing effect of the weighing mechanisms is varied during such movement

using electrical control means

with associated counting means

with associated check-weighing means

Sorting according to other particular properties

342

according to optical properties, e.g. colour

344

according to electric or electromagnetic properties

346

according to radioactive properties

Sorting apparatus characterised by the means used for distribution

Collecting or arranging articles in groups

Sorting by hand only

Compartmented furniture, e.g. pigeon-holes (storage racks B65G)

Apparatus or accessories for hand picking

Sorting, with or without orientating, not otherwise provided for
