Abstract

Siding station for pneumatic postal tube systems operating in both directions with separate receiving and despatch pipes for each, emanating from the points leading to the despatch or receiving point selectively connected to the main arrival conveyor pipe by the points. The points have, in addition to the despatch and receiving pipes, at least one further, thrid outlet for an onward leading conveyor pipe, or alternatively two additional outlets for the receiving and despatch pipes of a further station. The siding station avoids the normally high technical expense needed to cope with the problem of two cartridges travelling at the same time i.e. by-pass for arriving cartridge and by-pass for oncoming cartridge. The minimum of two exists in the present invention offers a choice of travel to the main pipe.

Description

Designation: Pneumatic tube switch station for turning operation pneumatic tube stations, which are connected to the track with a switch need in the case of automatic Departure control ("send memory") extensive mechanical and electrical equipment, so that a can can get there even if another is at the same time The rifle is there in the retracted position. Occasionally, especially when connected on a turning operation system with a horizontally running Pahrrohr, this is Problem also solved by the fact that in addition to a switch for the incoming cans an additional switch is installed for the departing rifles.

The considerable technical effort and space required in both cases can be avoided if the station in question is given a tight (i.e. no tongue) Assigns switch with two or preferably more than two outputs. Then you can the main rail of the system via the switch, optionally with the receiving pipeline to the station for extending a bushing or to the transmission pipeline for driving off a can. That is the subject of the present invention.

Details can be found in the attached schematic drawings and from the following description: The illustration shows an excerpt from a Pneumatic tube system, whose main tube 1, which is intended to be extended to the left, leads to further ones Stations and the compressor device, which leads the system with propellant air provided. These components, like the electrical control devices, are Limit switches, etc. neither in the description nor in the drawings explained because they are known in principle and are not the subject of the registered property rights.

In the part of the pneumatic tube system shown in the drawing are on the main carriage 1 dense points 2 to 6 arranged, from which, among other things, secondary (branch) driving tubes 7, 8 and 9 are branched off. While the auxiliary travel tube 7 ends at the switch 10, are the auxiliary tubes 8 and 9 to further, not shown here, stations leading to think The flexible or pivotable switch tube 11 in switch 2, the shown in the drive-through position (connection to the main driving tube) is, can also optionally be in pos. 12 (to the auxiliary drive tube 7) or in pos. 13 (exit to send / receive station 15) or in pos. 14 (departure from station 15). For this purpose, switch 2 has 4 outputs.

A pneumatic tube carrier intended for station 15 must -possibly via reversal of direction - can be moved in such a way that it opens from the left in print mode the switch 2 closes and is passed via pos. 13 into the arrival pipe 16.

There it is stopped in the extension shoe 17 and into the collecting container 18 ejected.

An outgoing liner at station 15 is inserted into the open end 20 of the Transmitter tube 19 inserted and after switching the switch 2 in pos. 14 in suction mode gone.

In the examples shown are the receiving tubes of all stations shown with exit shoe. As far as the approach is from above (as with the stations 21, 24 and 25), no collecting container is required because the arrived Can stack the cans in the receiving tube until they are removed. Where the approach from below (Station i5,22,23) or horizontally (Station 26) are, however, collecting containers (like 18).

In the case of switch 3, the switch tube can optionally be set to five Set the starting positions, three of which lead to further travel pipe sections, two, however, as receiving or. Send pipe to station 22 belong.

At switch 4 it is shown how the stations 23 and 24 are both can be connected to the common switch 4 (four outputs), while the fifth Exit to the next driving tube.

At switch 5, the frequently occurring case is shown that a Station 25 is connected via its triple switch, the third output of which is to the continuing tube 1 goes.

At the end points of the main pipe line 1 and the secondary line 7 is shown at station 26 (switch 6) and station 21 (switch 10) that there in each case a double oak to connect the relevant transmitting and receiving tubes is sufficient.

Claims (4)

Pneumatic tube switch station for turning operation, characterized by a special one emanating from the switch and leading to the sending / receiving point Receiving tube and a transmitting tube that go through the switch with the incoming travel tube are optionally connected. 2. Pneumatic tube switch station according to claim 1, characterized in that that the switch in addition to the transmitting and receiving tubes at least one more (third) exit for a further driving tube. 3. Pneumatic tube switch station according to claim 1 or 2, characterized in that that they have at least two additional outputs for each a sending and receiving pipe another send / receive point. 4. Pneumatic tube switch station according to claim 1 or one of the following, characterized characterized that the switch has at least 2 additional outputs for further Owns driving tubes.
