PURPOSE:To sample automatically the heterologous tissue material existing in a lumped material without the aid of man power by sampling the heterologous tissue material in the fragments which are cut by a cutter and are transferred in accordance with the command from a discrimination device. CONSTITUTION:The lumped material 1 contg. the heterologrous tissue material 1A to be sampled is first cut by the cutter to the fragment 1' consisting essentially of the lumped material and the fragment 1A' consisting of the material 1A. These fragments 1', 1A' are transferred by a conveyor 3 and are charged into a pipeline 4. The fragments 1', 1A' fall and pass thereupon together with liquid W in the pipeline 4. A TV camera 10 photographs these fragments 1', 1A' in this stage and outputs the video thereof to a discrimination device 11. The device 11 measures the quantity of the light reflected from the fragments from the video signal of the camera 10 and outputs an open signal to a valve controller 8 when the measured value If is larger than a certain value If0 (the quantity of the light reflected from the fragment 1'). The valve 7 is opened and the fragments 1A' of the material 1A are thus captured in a vessel 5. |
