Title: Deciding method of life or death of shellfish
Inventor: MIYAMOTO NOBUYUKI
IPC: G01N29/12
Filed: 1984-08-25
Abstract: PURPOSE:To detect dead shellfishes among living shellfishes, and to save the labor for selecting dead shellfishes and to speed up the operation by checking the frequency distribution of an oscillation or impact sound due to a collision between a shellfish and a plate member. CONSTITUTION:Shellfishes 4 are guided by an oscillatory plate 5, which is fitted in an oscillatory state to a fixed base 7 through springs 15 and oscillated by an exciter 6. Then, its oscillation is detected by an oscillation sensor 8. A flow frequency range below a specific value is obtained for a living shellfish, but not obtained for a dead shellfish. A decision and control part 13 amplifies a signal from the oscillation sensor 8 by an amplifier 13a and sends only its low frequency component to a comparison part 13d through a low-pass filter 13b, and the comparison that 13d decides on the dead shellfish when the signal is lower than the given reference value of a setting part 13c and sends a signal to a timing circuit 13e. The timing circuit 13e outputs a control signal at the timing of the conveyance of the shellfish on the oscillatory plate 5 to a selecting damper 9, thereby operating a damper driving part 10. Consequently, the selecting damper 9 is driven to rotate as shown by an arrow B, and consequently the dead shellfish falls on a dead shellfish conveyor 12 and is conveyed.

The CPU 11 reads out a comparing instruction at the time of judging the contact point instruction is turned on by flag information stored in the memory 13. In this case the CPU 11 executes the comparing instruction described in the processing program based on comparing object input channel number, comparing value information showing the comparing value and outputting destination information showing the outputting destination to be outputted as the signal of ON/OFF of the contents of the comparing result. Thus, description of the program is facilitated.
