PURPOSE:To make it possible to exactly operate a supply equipment in which a bellowslike chute is raised by stages as a storage in a container increases by constructing the equipment such that the chute is raised by the weight of the storage and a shutter is closed upon the completion of operation. CONSTITUTION:Fruit or the like is thrown into a hopper 9 from a supply stand through a conveyer. At this time, a framework 17 extends to its lowermost position in the container 38 on a balance 39 and the fruit slowly moves to the bottom in a zigzag direction through respective falling bags 19 to be stored in the container 38. When the weight of the storage reaches a given value, a switch in the balance 39 is closed to energize a motor 23, which operates a winch 22 to wind up a wire 20, rising the framework 17 for a given time. When a further given value of the weight is reached, similarly the framework 17 that has been stopped is raised again for a given time. These operations are repeated. After the storage is completed, a shutter 11 is closed to prevent an excessive loading. Thus, an exact operation is secured. |
