Abstract

A transfer mechanism 10 is designed to transfer a test tube holder 11 from a magazine 12 to a position B beneath a vertically movable fiber optic probe 13, and then to return the holder to its position in the magazine. Magazine 12 contains a plurality of like holders, the magazine being moved linearly in a direction perpendicular to the drawing.

Transfer Mechanism

A transfer mechanism 10 is designed to transfer a test tube holder 11 from a magazine 12 to a position B beneath a vertically movable fiber optic probe 13, and then to return the holder to its position in the magazine. Magazine 12 contains a plurality of like holders, the magazine being moved linearly in a direction perpendicular to the drawing.

Magazine 12 and holders 11 are provided with notches 14 to receive a pin 15 mounted on a movable belt 16. Beneath bedplate 17, belt 16 is connected to a driving belt 18 by a pin 19. A reversible stepping motor 20 drives belt 18 which in turn moves belt 16 and pin 15.

The magazine 12 is movable so as to selectively position a desired holder 11 at an extraction station through which belt 16 extends. The extraction station is aligned with a trough 21 so that as a holder is extracted from magazine 12, it is moved through trough 21 to selectively position a test tube beneath probe 13. Belt 16 is in the form of a loop and rests on top of plate 17 and the bottom wall of trough 21. It may be of a chemically resistant material such as polytetrafluoroethylene.

As the belt 16 passes through bedplate 17, wipers 23 prevent any liquid from passing from on top of plate 17 to the mechanism beneath the plate. The advantage of this system is that should any spillage occur within trough 21, the spillage is substantially confined to the trough. In addition, any spillage is prevented from passing through the plate 17.
