Abstract

This invention relates to an automated apparatus for subjecting samples to one or more selected test procedures at one or more test stations comprising a conveyor line for transporting samples contained in uniquely labeled containers, said line having at least two lanes for routing said containers to one or more selectable test stations, at least one of said lanes being a transport lane and at least one of said lanes being a queue lane, and having a container interface device for transferring containers to said testing device from the queue lane and back again onto said queue lane.

Claims

1. An automated apparatus for subjecting samples to one or more selected test procedures at respective test stations, said apparatus comprising;

a first conveyor line for transporting samples contained in uniquely labeled containers, said line having at least two lanes with means for routing containers between said lanes, at least one lane being a transport lane and at least one other lane being an accumulator lane,

loading means for loading said containers onto the apparatus,

electronic means for reading and recording the unique label information from said labels of containers,

data processing means for electronically recording, storing and processing said information,

electronic control means for routing and tracking said samples in response to said recorded information,

at least one interface means for routing containers from the first conveyor line to a spur conveyor line,

one or more spur conveyor lines for transporting said containers to one or more selectable test stations, said spur line(s) having at least two lanes, with means for routing containers between said lanes, at least one of said lanes being a transport lane and at least one of said lanes being a queue lane, and having a container interface device and a sample testing procedure located adjacent to said spur line(s),

selection means and routing means, controlled by said data processing means, for selecting containers for routing by the interface device from the first conveyor transport lane to the transport lane of a selected spur line,

selection means and routing means, controlled by said data processing means, for selecting containers and for routing selected containers from the spur transport lane to the queue lane adjacent to a selected test station,

a container interface device for presenting a container or sample from the container to a test procedure and capable of interacting with a container in the queue lane and the staging area of a test procedure,

test means for carrying out the test procedure,

means to record and store the results of the said test procedure,

means to route containers from the queue lane to the spur line transport lane,

at least one interface means for routing containers from the spur conveyor line to the first conveyor line,

off-loading means to off-load containers from the apparatus.

2. A device according to claim 1 wherein the data processing means can automatically reroutes a container by interposing a retest or new test based on data received from a testing device.

3. A device according to any one of claims 2 wherein said fast conveyor line has a decapping device for automatically decapping said containers.

4. A device according to any one of claims 3 wherein the interface means for routing containers from the first conveyor line to a spur line is an active gate controlled by the electronic control means which reads the unique label on a container just before the gate and causes a gate mechanism to redirect the container to another lane of the conveyor belt.

5. A device according to any one of claim 4 which has two lanes on the first line and two lanes on a spur line.
