Abstract

A pneumatic tube system, including at least one system control module for controlling delivery of a pneumatic carrier through pneumatic tubing. The system includes at least one pneumatic tube station having a sealer, the sealer includes a heating pad and a sealing strip, where the sealer automatically grips the open end within the heating pad and the sealing strip upon insertion of the bag into the system. In one example, the sealer creates a vacuum to extract air from an interior space of the bag. The sealer applies heat to the open end to seal the bag. The system includes at least one pneumatic tube station configured for sending at least one carrier, the at least one sending pneumatic tube station being in signal communication with the at least one system control module, where the at least one carrier is sent through the system by pneumatic tubing.

Claims

1. A system for transporting a sealed bag through pneumatic tubing, comprising:

at least one system control module comprising;

at least one database module; and

at least one computer control center module in signal communication with said database module;

a carrier bag having an open edge and three closed edges forming a cavity therein for receiving contents;

at least one pneumatic tube station having a sealer for vacuum sealing said carrier bag to encapsulate said contents within said carrier bag, and

at least one carrier to be routed from said pneumatic tube station to a destination;

wherein said sealer includes a vacuum device, a heating pad, a switch, and a sealing strip, wherein said bag automatically activates said switch upon insertion of said bag between said heating pad and said sealing strip,

wherein said sealing strip and said heating pad holds said bag therebetween in response to activation of said switch, and wherein said vacuum device evacuates air from said cavity prior to applying heat to the open end to seal said open end and form said sealed bag,

wherein said at least one carrier is adapted for receiving said sealed bag,

wherein said at least one pneumatic tube station is configured for sending at least one carrier to said destination, said at least one sending pneumatic tube station being in signal communication with said at least one system control module, wherein said at least one carrier is sent through said system by said pneumatic tubing,

wherein said at least one system control module receives tracking information associated with sending and receiving said at least one carrier,

wherein said at least one computer control center module is configured to receive delivery information relating to routing said carrier from said pneumatic tube station to said destination from said at least one pneumatic tube station,

wherein said at least one database module is configured to store said delivery information from said computer control center module, and

wherein said at least one computer control center module is further configured to interpret said delivery information and transmit said delivery information to said at least one pneumatic tube station to control routing of said at least one carrier from said pneumatic tube station to said destination in said pneumatic tubing.

2. The system of claim 1, further comprising a vacuum device for applying a vacuum to extract air from an interior space of said carrier bag.

3. The system of claim 2, wherein said sealer includes a compressor for creating a vacuum.

4. The system of claim 1, wherein said sealer comprises means for gripping said carrier bag between said heating pad and said sealing strip.

5. The system of claim 1, wherein said sealer applies heat to said carrier bag through said heating pad.

6. The system of claim 5, wherein said sealer is preprogrammed to apply heat to said carrier bag for a predetermined time.

7. The system of claim 4, wherein said gripping means comprises of a plurality of piston rods.

8. The system of claim 7, wherein said sealer comprises a compressor for applying a compressive force on said plurality of piston rods.

9. The system of claim 3, wherein said sealer comprises a first relay switch programmed for controlling said vacuum applied to said carrier bag.

10. The system of claim 2, wherein said sealer comprises a second relay switch programmed for controlling said heat applied to said carrier bag.

11. The system of claim 1, further comprising at least one slide plate disposed in said pneumatic tubing for holding said at least one carrier above said at least one pneumatic tube station, wherein said at least one side plate holding said at least one carrier until a user scans information regarding identification of said user by said at least one computer control center module.

12. The system of claim 1, further comprising at least one identifying tag reader configured for reading identifier tags associated with said at least one carrier.

13. The system of claim 12, wherein said identifier tags are one of an optically scannable identifier tag or a RFID tag.

14. he system of claim 12, wherein said at least one identifying tag reader is a handheld Personal Digital Assistant.
