Pneumatic tube conveyor station

A pneumatic tube conveyor station for dispatching or receiving a conveying case of a predetermined length (L), comprising:

• a housing comprising an upper horizontal member having a first opening therein, a lower horizontal support member, and a vertical member having a second opening therein slightly larger than said predetermined length (L), said second opening defining an axis;
• a pneumatic conveyor tube connected to the upper surface of said upper horizontal member in alignment with said first opening;
• sealing means arranged around said first opening on the lower surface of said upper horizontal member;
• a displaceable tube section arranged adjacent said second opening and aligned underneath said first opening, said tube section comprising an upper end adapted for mating said sealing means;
• first displacing means for displacing said tube section along said axis, said tube section abutting said first opening and said upper end of said tube section mating with said sealing means when in a first operational position and said tube section being separated from said first opening by a distance greater than said predetermined length (L) when in second and third operational positions;
• axial stop means arranged coaxially with said axis for stopping an arriving conveying case in an axial position;
• second displacing means for displacing a conveying case in a direction perpendicular to said axis between a load position wherein said conveying case is located parallel to said axis and at a distance therefrom and a dispatch position wherein said conveying case is located coaxially to said axis, and between a receive position wherein said conveying case is located coaxially to said axis and an unload position wherein said conveying case is located parallel to said axis and at a distance therefrom.
