Definitions

  • This invention relates to pneumatic tube systems and more particularly to stations in systems which are able to receive carriers from either direction, dispense carriers in either direction, or let undesired carriers pass right through.
  • the opening is in the leading portion of the tube. This is undesirable as carriers which arrive at the intermediate station with a low kinetic energy (due to friction or low weight) may be stopped by the ejector and not ejected from the opening. If this occurs, an attendant must immediately remove the carrier in order to prevent a foul-up in the entire system.
  • Using an ejector also has the disadvantage that the opening of the tube must be very long and, consequently, very long cabinets and large spaces for the station are required.
  • An intermediate station according to my invention is disposed in an air-tight cabinet and comprises an opening in the forwarding tube for ejecting and inserting the carriers without the disadvantages of known arrangements.
  • the forwarding tube is equipped with a bent elbow in the forwarding tube between the entrance and exit of my station, an opening in the bent elbow, and a movable cover for the opening.
  • the curved elbow is designed in such a way that the recess of the curve leads to one side or to the bottom so that a carrier cannot remain in the recess but must fall out of the opening in the bottom or side of the recess if the cover is open.
  • the carrier passes through the station only when the cover is closed, because the tube elbow will deviate even a quickly moving carrier so that it will be forced towards the opening and cannot continue its run or drive in the following tube section.
  • the airtight case guarantees that the pneumatic conditions in the tube do not essentially change when a carrier is ejected, and that preceding carriers are not impaired in their run. The case will only be opened if a carrier is to be dispatched or received and this can be done quickly so that the pneumatic conditions in the system are not greatly affected.
  • FIGURE 1 is a cross-sectional view of an intermediate station according to my invention
  • FIGURE 2 is a side-elevational view of a tube section at the intermediate station.
  • FIGURE 3 is a cross-sectional view of a station in accordance with my invention.
  • FIG. 1 a for warding tube 1 enclosed in an air-tight case 2.
  • the entrance 3 and exit 4 are hermetically sealed at their junctions of tube 1.
  • various elements are omitted in drawings 1 and 2.
  • exit 4 is not shown in drawing 3 and either is the bent portion of tube 1 which leads to it.
  • the symmetrical curvature of tube 1 commences at entrance 3 and ends at exit 4.
  • the curvature of recess 5 is directed toward the bottom of case 2 and has an opening 6 disposed in its lowermost portion.
  • Cover 7 when covering aperture 6 provides an air-tight seal.
  • Cover 7 is mounted on a swivel arm 8 which is pivotally mounted in case 2 on bar 9.
  • the movement of arm 3 to bring cover 7 into and out of operative relationship with opening 6 is controlled by electromagnet 10 which moves the cover away from the opening in opposition to a spring (not shown) which tends to hold cover 7 over opening 6.
  • Door 11 provides access to case 2.
  • Sections or portions 12 and 13 represent those areas of the forwarding tube 1 which alter the axis of travel of the carrier; one of these portions alters the carrier travel from the received axis to another axis, and the other portion returns the carrier to the original (received) axis.
  • Portion 14 interconnects the two and provides the deposit or withdrawal opening 6.
  • the forwarding tube 1 can be mounted as shown in FIGURES 1 and 3, with the opening 6 at the bottom, or it can be rotated to present a side opening.
  • the objects of the invention are served, equally well, with the tube mounted either way. It is to be noted, that carriers may be received from either direction, may be dispensed in either direction, or may pass through the station without interference.
  • a pneumatic tube station for receiving carriers conveyed in either direction, for dispatching carriers in either direction, and for throughgoing passage of carriers in a forwarding tube system, comprising:
  • a forwarding tube for the reception and discharge of carriers, said tube having first and second portions which present, respectively, descending and ascending pathways, and a third portion interposed between said first and second portions having an opening along its lower wall portion, said opening being of a size to permit passage therethrough of said carriers;
  • a pneumatic tube station according to claim 1, wherein said first and second portions are each curved in an identical convex attitude and said third portion is curved in a concave attitude.
  • a pneumatic tube station according to claim 1, wherein said housing has an access door with means for opening and closing said door;
  • said cover moving means comprises an electromagnet
  • a pneumatic tube station according to claim 2
