Definitions

  • each partial route represents a pneumatic separate system, operated by pressing or suction air or by both types of operating air.
  • the invention relates to a pneumatic tube system for high speed of the dispatch carrier and a long driving route, subdivided pneumatically into individual partial routes, at the end of which the operating air is eifective, so that the air becomes solely or preferably effective in the respective partial route in which a dispatch carrier is at that moment. Thereby sluices and locking slides as well as other lockings of the drive tube should be avoided.
  • the invention consists in that the drive tube is connected to the operating air supply respectively to the surrounding atmosphere via valves, controlled by the moving dispatch carrier, so that the high speed is obtained only in that drive tube section in which the dispatch carrier is at the moment.
  • a common blower is suitably provided for the supply of operating air, which is connected with the valves, leading to the drive tube through separate tube lines or pipes.
  • This air is particularly suitable for systems to be newly installed, because the separate line can be installed. simultaneously with the drive tube.
  • the diameter of the tubes must be so large that the line represents only a negligible resistance for the operating air.
  • the blower can be a suction type or a compression type blower, it is also possible to use blowers of both kinds with a separate tube for each operating phase.
  • the drawing 1 represents the drive tube, in which the dispatch carrier is moved from left to right.
  • valves are controlled electro-magnetically by a system not shown on the drawing which system is again actuated by the indicators 13, 23, 33, 43, and 53.
  • the drive tube 1 further control valves 12, 22, 32, 42 are provided which lead to the surrounding atmosphere.
  • the system operates as follows: Both blowers operate and the air in the system is correspondingly pretensioned.
  • the valves 11, 21, 31, 41 are open, the valves 12, 22, 32, 42 are closed.
  • the dispatch carrier inserted into the drive tube on the left end is moved by the suction air in the direction of the arrow and bypasses at first the indicating device 13.
  • Now valve 11 is closed and valve 12 opens.
  • the suction air current enters essentially through the valve 12 and moves the carrier in the driving direction till it has reached the indicating device 23.
  • valve 21 closes and valve 22 opens so that the suction air current becomes elfective through said valve.
  • valve 31 is closed and valve 32 opens.
  • the system When passing through the indicating device 53 the system is switched back to the original condition, i.e. the valves 11, 21, 31, 41 open and the valves 12, 22, 32, 42 close and the system can be used to dispatch another carrier.
  • the first carrier enters into the braking section 2 equipped with the speed-stabilising blower 5 in which an essentially lower current speed prevails. It finally takes this speed and enters into the receiving station at a correspondingly reduced speed.
  • dispatching a carrier by a dispatching station not shown on the drawing, into the drive tube sections 8, 9, 10, or 14, the valves switch into the same condition as when the carrier would pass over the indicating devices 13, 23, 33 or 43, located in front of said respective section.
  • the indicating devices 13, 23, 33, 43, and 53 are simple drive tube contacts. Due to the high speed with which the system operates it is recommended to use devices which are not equipped with contacts to be mechanically actuated by the dispatch carrier. Such devices are for example light bars or magnetic indicators.
  • a pneumatic tube system comprising:
  • a source of operating air coupled to said drive tube, having air-moving power of a magnitude less than that required to said drive tube;
  • valves associated with each of said ports sequentially operable, to control passage of air through said ports
  • control means coupled to said valves to actuate said valves sequentially, said control means being responsive to the movement of said carrier along said drive tube.
  • a pneumatic tube system according to claim 1, wherein:
  • said drive tube is sectioned; said ports comprise a plurality of air pipes one each located at the end of each of said drive tube sections; said valves comprise a first plurality of air valves, one of each valve of said first plurality of valves being coupled to each said air pipe, and a second plurality of air valves interposed between said drive tube and said operating air source; and said control means comprises indicating devices, re-
  • a pneumatic tube system according to claim 1, wherein:
  • a pneumatic tube system according to claim 1, wherein:
  • said source of operating air is an air-vacuum device which extracts air from said drive tube.
  • a braking section connected to the terminal end of said drive tube, in which dispatch carrier speed is reduced.
  • said braking section includes an air line bridged across and through-connected with said drive tube having an air-impeller device coupled thereto.
