DISPERSIVE SUPPLY APPARATUS OF COMBINED WEIGHING APPARATUS

PURPOSE:To maintain an approximately constant quantity in each of the second trough at all times and to supply a uniformly dispersed quantity, by pointing a chute to the second trough having no material to be weighed in the neighborhood of an end part and providing a sensor for operating the first trough corresponding to the chute. CONSTITUTION:A material to be weighed is sent from a discharge cylinder 14 to a weighing part 4 through the first trough 27 constituting a supply apparatus 5, a chute 30 and the second trough 29 and is supplied to a pool hopper 21 and a weighing hopper 19. The quantity to be introduced from a storage hopper 9 to the first trough 27 is controlled and the material to be weighed in the two first troughs 27, 27 is held in comparatively small and approximately constant quantities and moreover, supplied through the chutes 30, 30 so as to disperse said material to the five second troughs 29-29. The second trough having no material to be weighed in the neighborhood of an end part 29a is pointed and also, only a vibration device of the first trough 27 corresponding to the chute 30 is operated. The material is supplied so as to replenish to the second trough having no material to be weighed.
