US 4,529,335 A · System for transferring carrier from one pneumatic carrier receiving/dispatching station to another

Abstract

A system for transferring pneumatic carriers from one pneumatic carrier receiving/dispatching station to another includes a first pneumatic carrier diverter, or a plurality of such first diverters, each with an inlet/outlet linked through pneumatically-sealed tubes to at least one such station, a multiplicity of outlets, and a device for shiftably linking the inlet/outlet of the diverter to any one of its multiple outlets; a second pneumatic carrier diverter, or a plurality of such second diverters, each with a multiplicity of inlets and a single outlet, and a mechanism for shiftably linking the multiplicity of inlets to the outlets; the system including either a plurality of such first diverters, or a plurality of such second diverters, or both; pneumatically-sealed tubes joining, in parallel, all the diverters of the first kind of all the diverters of the second kind; and a pressure/vacuum supply device joined to the outlet of one or more of the second kind.

Dependent claims

A system for transferring pneumatic carriers from one pneumatic carrier receiving/dispatching station to another comprising a first group of pneumatic carrier diverters, each with an inlet linked through pneumatically-sealed tubes to at least one of said stations, a multiplicity of outlet means, and means for shiftably linking said inlet means to any one of said outlet means;

a second group of said diverters, each with a multiplicity of inlet means and an outlet means, and means for shiftably linking said multiplicity of inlet means to said outlet means, said transferring system including a plurality of diverters of said first group and a plurality of diverters of said second group with at least three diverters and at least one of said first and said second groups of diverters;
pneumatically-sealed tubes joining in parallel, all the diverters of said first group to all the diverters of said second group;
and at least one means for supplying pressure and vacuum to said system, joined to the outlet means of a diverter of said second group.

A pneumatic tube system including:

(a) A system for transferring pneumatic carriers from one pneumatic carrier receiving/dispatching station to another comprising a first group of pneumatic carrier diverters, each with an inlet linked through pneumatically-sealed tubes to at least one of said stations, a multiplicity of outlet means, and means for shiftably linking said inlet means to any one of said outlet means;
a second group of said diverters, each with a multiplicity of inlet means and an outlet means, and means for shiftably linking said multiplicity of inlet means to said outlet means, said transferring system including a plurality of diverters of said first group, and a plurality of diverters of said second group with at least three diverters and at least one of said first and said second groups of diverters;
pneumatically-sealed tubes joining, in parallel, all the diverters of said first group to all the diverters of said second group;
and at least one means for supplying pressure and vacuum to said system, joined to the outlet means of a diverter of said second group;
and
(b) At least two separate groups of stations, each station group including a single inlet/outlet pneumatic tube joined to the inlet means of one, and only one diverter of said first group of diverters, wherein said pneumatic tube system permits transferring a pneumatic carrier from one station group to another station group with no more than one shift in each diverter through which said pneumatic carrier passes.
