Abstract
An automatic test tube recapper is presented that is capable of recapping thousands of test tubes per day. Specially designed caps are poured into an upper triangular shaped hopper. The randomly oriented caps are transported by a pair of belts to an upper slide. Misaligned caps are rejected and fall back into the hopper, while properly aligned caps slide down the slide to a cap catch, one at a time. A hammer shaft then drives the cap into the top of the test tube until the cap is firmly seated. The hammer shaft reverses, which withdraws the shaft upwards. As the hammer shaft moves upwards, it triggers a pair of arms that allows another cap to fall into the cap catch. A conveyor also automatically moves the next uncapped test tube under the cap. The cycle then repeats itself.
