Abstract

A machine for sorting objects of various destinations, particularly for bulky postal correspondence. A guide defines a path passing through at least one loading station and at least one sorting station. At least one succession of compartments for containing individual objects is moved along said guide. Each compartment is in the form of a narrow pigeon hole, which has its surface of maximum size perpendicular to the direction of movement of the compartment and is provided with an operable base wall.

Claims

1. A machine for sorting objects of various destinations, particularly suitable for bulky postal correspondence, comprising a guide defining a path of varying configuration and passing through at least one loading station including at least one loading position which is fed in succession with the objects to be sorted, and at least one sorting station including at least one succession of collection containers for objects of different destination, and at least one succession of compartments for containing individual objects, said compartments being in packs of single units independently movable one in respect of the others along said guide in order to convey the objects from said loading station to said sorting station, said compartments being in the form of narrow pigeon holes having their surface of maximum size perpendicular to the direction of movement, said pigeon holes being provided with base walls which can be opened on command in order to discharge the objects into said collection containers, said loading station providing for means for conveying said objects to said compartments, said conveying means comprising coupling means which can be operated in order to momentarily connect said conveying means to said compartments.

2. A machine as claimed in claim 1, wherein said narrow compartments are periodically interspersed with compartments of greater width.

3. A machine as claimed in claim 1, wherein said compartments are open upperly for loading the objects.

4. A machine as claimed in claim 1, wherein said single movable units include packs of mutually rigid compartments.

5. A machine as claimed in claim 4, wherein said packs of compartments are assembled in pairs to form carriages comprising one pack of compartments on each side of said guide, said sorting station including two successions of collection containers disposed likewise on the two sides of said guide.

6. A machine as claimed in claim 1, wherein said conveying means includes at least one chute for conveying the objects towards said compartments.

7. A machine as claimed in claim 6, wherein said chute can be rotated from a substantially horizontal position for receiving an object to be loaded, to a substantially vertical position for discharging the object into the relative compartment.

8. A machine as claimed in claim 1, wherein said guide is constituted by a rail arranged to support and guide self-driven carriages.

9. A machine as claimed in claim 1, wherein said guide is constituted by a support and guide rail, in which the carriages can be connected to and separated from a chain drive system.

10. A machine as claimed in claim 1, wherein said guide is for carriages on the ground, its purpose being to provide a fixed physical datum, but not necessarily by means of a mechanical connection, in order to be able to control any transverse motion of the carriages to the necessary extent.
