Pneumatic delivery system and methods for use

A method comprising:

• moving a canister through a tube comprising a tube wall and a channel extending within the tube wall;
• positioning the canister proximate a tube opening within the tube wall;
• engaging the canister with a first transfer arm and a second transfer arm when the canister is at a first position;
• moving the first transfer arm and the second transfer arm through the tube opening to position the canister external to the tube wall;
• rotating the first transfer arm and the second transfer arm to change an orientation of the canister from the first position to a second position;
• and
• removing the canister from the first transfer arm and the second transfer arm.

A system comprising:

• a tube comprising a tube wall and a channel extended within the tube wall, wherein the tube is configured to move a canister through the channel pneumatically;
• a tube opening within the tube wall;
• and
• a transfer mechanism comprising a shaft, a first transfer arm, and a second transfer arm, each of the first transfer arm and the second transfer arm comprising a first transfer arm end and a second transfer arm end, the first transfer arm end is pivotably coupled to the transfer shaft, the first transfer arm and the second transfer arm movable between an open position and a closed position, wherein:
• the transfer mechanism is configured to engage the canister via the first transfer arm and the second transfer arm while in a first transfer position, extend the transfer shaft to position the first transfer arm and the second transfer arm through the tube opening, and rotate about the transfer shaft to change an orientation of the canister from the first transfer position to a second transfer position, and
• the first transfer arm and the second transfer arm are configured such that as the canister moves in a direction away from the first transfer arm end and towards the second transfer arm end, the first transfer arm and the second transfer arm move from the closed position to the open position,
• thereby permitting the canister to be removed from the transfer mechanism.
