PURPOSE:To generate a classification signal without a supporting pin and simplify the control of the machine by holding the supporting pin so as to wait with a solenoid signal and restoring the wait status when the supporting pin passes through a classification rail. CONSTITUTION:A classification rail 21 changes over a supporting pin 15 on a carrying cup to an upper rail 17 or a lower rail 27 to guide the pin. The classification rail 21 is held horizontal by a holding device 28. When the holding status of the holding device 28 is released by a command from a weighting device and the supporting pin 15 is separated from the classification rail 21, the classification rail 21 is restored horizontally. |
