Abstract
A grain cargo automatic metering and dispensing system, which utilizes microcomputers to register the data of the ingredients and quantity of a prescribed formula and simultaneously control the storage and the feeding of prescribed materials, the operation of a mechanical hand to take up and let off empty containers, the operation of a weighing system and the operation of a conveyer system. Therefore, material dispensing operation can be accurately and efficiently executed through computer control to eliminate any possible human error.
Claims7
A grain cargo automatic metering and dispensing system, including:
- a material suck-in and storage system including a plurality of closed independent storage tanks each equipped with a heavy-duty suction pump for taking up grained or powdered material for storage therein;
- a feeding system comprised of a variety of computer-controlled screw rods to respectively send the grained or powdered materials out of said storage tanks for dispensing;
- a conveyer system being computer-controlled to deliver empty containers and material stuffed containers;
- an empty container take-up and let-off system comprising a computer-controlled mechanical hand to take up and place empty containers on said conveyer system;
- a container shifting and weighing system comprising a programmable weighing system and a mechanical hand, said mechanical hand being capable of rotating on its own axis through an angle of 180.degree. so as to simultaneously take up a material stuffed container and an empty container for shifting, permitting said empty container to be placed on said weighing system and said material stuffed container to be placed on said conveyer system;
- a dispensing and inventory operation microcomputer system for the registration of prescribed formula and inventory data, having a printer for printing out the data stored therein;
- a metering control microcomputer system connected with said dispensing and inventory operation microcomputer system for on-line operation to fetch the data therefrom so as to control the operation of said mechanical hand and said weighing system;
- an electric engineering control unit controlled by said metering control microcomputer system to start, control and stop all operations of the system;
- a radio remote control system being an auxiliary signal input device to replace the key-in operation of the keyboards of the microcomputers of said metering control microcomputer system and said dispensing and inventory operation microcomputer system.
