PURPOSE:To perform automatic winding without overlapping fibriform samples, which are flowing out, by controlling the rotation of a winding drum in correspondence with the flowing-out speed of the samples. CONSTITUTION:A data processing device 1 obtains the value of the flow rate of a sample from the amount of displacement DELTAx of a plunger 3, which compresses the sample fluid in a cylinder 2. The number of rotation of a winding drum per unit time is computed based on the flow-rate value and the length of the outflow of the flowed-out sample 19. Then, a pulse generator 12 outputs the pulses corresponding to the computed number of rotation and imparts the output to a pulse driving circuit 13. A pulse motor 14, which is rotated in correspondence with the pulses, rotates the winding drum 18 and moves it in the direction of a rotary shaft back and forth. As a result, overlapping of the flowed-out samples 19 can be prevented, and the sample is uniformly wound-in around the outer surface of the drum 18. Thus the fibriform flowed-out samples can be automatically wound without overlapping. |
