Definitions

  • This invention relates to pneumatic-tube systems, and more particularly to a system arrangement wherein carriers can be stored and the foremost of several stored carriers can be dispatched from storage upon request.
  • detour airline which is used in controlling the number of carriers stored in the drive tube of the arrangement, to decelerate received carriers, and to dispatch foremost carriers.
  • FIGURE 1 is a schematic drawing of one embodiment of the invention and FIGURE 2 is a schematic drawing of a modified version of the embodiment of FIGURE 1.
  • FIGURE 1 an input drive tube is shown, with three functional sections: 101, input section; 1b, storage section; and output section; and a detour airline 2 branching off therefrom and re-entering at point 3 near gate route or section 4.
  • the section 4 may be a receiver of the pneumatic-tube system, a code detector, a central station or another system which is pneumatically disconnected from the drive tube 1.
  • the use of a detour line as indicated 2 has the common purpose to reduce the speed of the carrier at the input section 111. If the carrier is moved slowly in said section, the detour airline 2 is not necessary.
  • the detour airline has valves 5 and 6 at either side of the connection G leading to a source of air suction G.
  • the drive tube 1 has a portion 7 which has a second detour airline 8 connected in parallel thereto. Said second airline Patented August 9,1965
  • a swivel-mounted, and thus retractable, stop 11 is inserted towards the output end of the drive tube portion 7.
  • a contact or switch 13 is positioned further back along the length of drive tube portion 7.
  • another contact or switch 15 is provided near the beginning of the drive tube section 7.
  • Each contact or switch 13, 14, or 15 is adapted to be actuated by a carrier in the tube adjacent thereto, and for this .purpose, such contact or switch may be provided with an operating arm extending into the tube so as to be mechanically actuated by a carrier.
  • a branch 12 is provided leading to the surrounding atmosphere via a controllable valve 16.
  • valve and the stop may be electrically operated and controlled from a central control station, which can be remotely located, this station being electrically connected to all contacts.
  • the central station controls these valves and the stop to provide the following operation:
  • stop 11 is first swivelled into the drive tube portion 7.
  • Valves 6 and 9 are open, and valve 5 is closed; thus air suction operates to feed carriers to drive tube 1.
  • Carriers arriving at tube portion 7 proceed down towards stop 11. Their travel is decelerated in that valve 9 is open and detour airline 3 shunts the air suction; a first carrier halts at stop 11, actuating switch (or contact) 13. Subsequent carriers are stored in line. As each a-ctuates contact 15, valve 9 is caused to close for a short time so as to shift all carriers against stop 11. When enough carriers are stored to hold contact 14 in the actuated position, dispatch of further carriers to storage is blocked. With the request of a foremost carrier, valve 16 is opened admitting air therethrough.
  • Valve 9 is closed, and stop 11 is retracted.
  • the admitted air operates mainly in the advancing direction, as the thick arrow indicates. A portion of the air impacts against the stored carriers to hold them in position. The foremost carrier is advanced and dispatched.
  • Contact 13 being released, stop 11 re-in-serts, valve 16 closes and valve 9 reopens.
  • valves 6 and 9 are closed and valve 5 is opened to shunt the air suction around drive tube 1, halting further feed of carriers beyond the input point.
  • a signal is conveyed to dispatching points, which signal blocks the dispatch of further carriers to storage.
  • stop 11 is swivelled out either by a central reporting point or by a station having requested the carrier.
  • Valve 5 is closed and valves 6 and 9 are opened. Open valves 6 and 9 cause the air suction to act on the foremost carrier just released and dispatch it along to and through gate route 4.
  • Contact 13, then, is released and upon its release it causes stop 11 to insert itself into the tube.
  • the last-stored carrier advances, with all stored carriers, down drive tube portion 7, releasing contact 14.
  • the blocking signal sent to dispatching points is halted; hence, at least one more carrier can be accepted for storage.
  • the advance of all carriers down drive tube portion 7 causes contact 13 to be actuated; this causes stop 11 to be inserted.
  • contact 14 is again actuated, closing valves 6 and 9 and opening valve 5. With the next request for a foremost carrier, the foregoing cycle is repeated.
  • FIGURE 2 shows a modification of the embodiment of FIGURE 1 wherein the branch outlet 12 is not used. Instead, the connecting points of the detour airlines 2 and 8 are shifted slightly.
  • Detour airline 2 is branched off downstream from detour airline 8, and detour airline 8 re-enters ahead of the stop 11.
  • valve 9 is closed and valve is open.
  • An arriving carrier is led towards stop 11, actuating contact 13.
  • Actuation of contact 13 causes valve 9 to open and valve 5 to close and simultaneously signals the availability of a carrier to a central reporting point or to other stations.
  • a subsequently received carrier actuates contact 15, which in turn closes valve 9 and opens valve 5.
  • the air suction impels said carrier forward and against the preceding carrier (which is halted at stop 11).
  • a timing circuit opens valve 9 again, closes valve 5 and retracts stop 11.
  • the foremost carrier is conveyed out of the drive-tube storage area.
  • the succeeding carriers do not travel behind the foremost carrier, as no air impacts on them.
  • the air is shunted around them via detour airline 8.
  • stop 11 is caused to re-insert, and valve 9 is closed again and valve 5 is opened.

  • a substantially horizontal drive tube said drive tube having input and output sections and a storage section therebetween;
  • a first means normally inoperative, including a first detour air line connected to said drive tube between a point adjacent to the juncture of said input section and said storage section and said output section, for halting input of carriers for storage;
  • a second means normally operative, including a second detour air line shunt-connected to said drive tube substantially across said storage section, for controlling the movement of carriers into storage;
