A fixed quantity feed apparatus which includes a feeding device for shaping various kinds of articles such as bean sprouts, various cut vegetables, spaghetti and noodles, into the form of belt and conveying them, a weighing device for detecting that the articles which are being conveyed by the feeding device have reached a predetermined weight, and a dividing-feeding device for splitting up the belt-shaped articles when the weighing device has detected the predetermined weight, wherein the articles are divided by the fixed weight and fed to a packing device or the like, while they are continuously conveyed.

A feed control system for a plurality of packaging machines is provided wherein the overall supply to the machines is controlled in accordance with total demand. A pulse is produced by each machine after a filling and sealing operation is completed and a weight constant multiplier is employed to multiply this pulse by a weight constant associated with the package (the number of grams or ounces contained in the package). The outputs of all of the weight constant multipliers are connected to a parallel to series converter which produces a signal in the form of a pulse train representative of the total weight requirements of all packaging machines per unit time. This signal is converted into a corresponding voltage level which is utilized by a storage conveyor motor controller to control the overall feed rate to the machines.

Feed dispensing apparatus for delivering weighed amounts of feed to poultry and the like is disclosed, and an associated method of feed delivery is described. At a predesignated time, a time switch starts a filling operation by actuating a first conveyor, which transports feed from a bulk storage bin to a receiving hopper. A weighing device connected to the hopper weighs the feed being delivered, and when a predetermined weight of feed has been received in the hopper, the weighing device actuates an automatic valve to halt further feed delivery to the hopper. If a plurality of hoppers are used, the hoppers are filled in seriatim order, and filling the last hopper halts operation of the first conveyor. A switch is provided to insure that refilling of the hoppers does not occur until a second predetermined time is reached. After the hoppers are filled, the time switch starts a feeding operation by actuating a second conveyor to deliver feed from the weighing hopper or hoppers to poultry feeding stations. High feed level sensors are provided to halt operation of the second conveyor if a maximum level of feed is exceeded in the feeding stations. When the flock consumes feed to a level below the high feed level sensors, the second conveyor is reactuated, and more feed is delivered to the poultry feeding stations. A hopper low feed level sensor halts further operation of the second conveyor when a minimum level of feed is reached in the hopper. At the second predetermined time, the first conveyor is again actuated, and the filling and feeding cycle is repeated.
摘要:
An apparatus for charging a refrigeration system with a predetermined amount of refrigerant by weight. The apparatus includes a cylinder which is mounted on top of a strain gauge scale that is first filled from a source of refrigrant and then automatically discharged to fill a refrigeration system with a predetermined amount of refrigerant. The system includes solenoid operated valves which are automatically operated for loading the cylinder and charging the refrigeration system. A vacuum pump is also included in the circuit for placing the refrigeration system under a predetermined vacuum prior to the charging operation.
