Abstract: An egg breaking knife used in an egg breaking device which increases the yield of the egg breaking device. The upper edge of the egg breaking knife is in a “V” shape. The “V” shape creates a lower drainage point to eliminate any “damming” of egg shell contents which may occur in the egg shell halves. The knife edge of the egg breaking knife of the present invention may also include a vertical slot or opening, preferably at the vertex or intersection point of the “V” shape, which assists in preventing “damming” of egg contents and enhances the drainage of egg contents from the egg shell halves. The lower edge of the egg breaking knife of the present invention may include a drip point, preferably located below the vertical slot, which serves to collect all egg content drippage at a single location, to ensure that a minimal amount of egg content drippage remain adhered to the egg breaking knife during egg content dumping.

Abstract: An apparatus for conveying, cleaning, drying, oiling, candling, grading and packing eggs and high speeds. A main conveyor assembly, which includes two or more conveyors, transfers eggs continuously in spaced-apart, aligned relationship to transfer at which eggs are packaged according to their previously-determined individual physical characteristics, such as weight, cracks, dirt, etc. The conveyors can run in the same direction, or may run in opposite directions. The transfers accommodate the at least two conveyors, and include a section which gathers ejected eggs and may convey them to a packing station in a manner which prevents egg collisions. The eject mechanism for ejecting eggs from the conveyors ensures proper distribution of the eggs across a transfer so as to prevent egg collisions and to ensure that the packers are filled equally across their widths.

Abstract: The invention relates to a multiple-row egg breaking and separating machine in which the egg contents and egg shells are passed adjacent one another through an inspection station at which the contents of the egg can be rejected because the shell or contents are contaminated, defective or abnormal. The present invention is particularly useful for high-speed breaking operations, yet still allows the inspector to view all the parts of the eggs for possible rejection of the egg contents. The present invention is particularly suited for automatic scanning of egg shells and contents, and eliminates possible U.S. Food and Drug Administration (FDA) objections to prior art multiple-row egg breaking machines.

Abstract: The present invention is a device for weighing and breaking eggs, and a method for weighing and breaking eggs. The eggs are conveyed on a conveyor to an egg-weighing station, at which each egg is individually weighed. The weight of each egg is sent to a storage and processing device, where the weight values are summed to arrive at a total value for all eggs passing through the egg-weighing station. The eggs are then conveyed to an egg-breaking machine, which may also separate the contents of the eggs broken in the egg-breaking machine. The data in the processor can be used to accurately calculate the weight of eggs processed by the egg-breaking machine. In addition, this data can be used to calculate the yield of the machine, by comparing it with data regarding the weight of the shells of the broken eggs and the weight of the egg contents from the broken eggs.

Abstract: An apparatus for transferring eggs continuously conveyed in spaced-apart, aligned relationship by a conveyor to a receiving station at which eggs are packaged according to their individual physical characteristics. A frame on which solenoid-actuated plungers are mounted is disposed adjacent the conveyor at the receiving station for releasing eggs having the same physical characteristics from the conveyor in a predetermined sequence at the receiving station. The frame is movable with respect to the receiving station according to the speed of the conveyor.

Abstract: An automatic article stacking system wherein a plurality of articles to be stacked are arranged in layers prior to being stacked. The layers are advantageously arranged horizontally orthogonal to one another so as to enhance the stability of the stack. A measurement system is provided for determining whether any of the articles exceeds a predetermined size limit. In one embodiment which is arranged for stacking egg cartons, a determination that the egg carton exceeds the predetermined size limit signifies that the egg carton is open and, therefore, not in a form suitable for stacking. The open egg carton is conveyed under an elevator which accumulates the articles to be stacked, and to a discharge area. Thus, closed egg cartons are accumulated in layers and stacked. Successive layers of articles are stacked under prior stacked layers.

The pointer generates signals for simultaneously indicating the position of articles on the conveyor within the inspection area, and the type of article being identified.

Abstract: A cage door construction, useful for poultry cages and the like which are stacked one above another, has a door opening framed in a wall of the cage by vertical and horizontal wires. The vertical wires extend beyond the upper horizontal wire of the door frame and are bent over to become part of the top of the cage where they serve as guide wires for sliding movement of the cage door. The case door is formed of a single piece of wire bent into a U-shaped with lateral arms extending outward from the open end therof. Each laterally extending arm is provided at its end with an eye which slidably engages one of the guide wires. Indentations, formed in the legs of the U-shaped door, can lock into place under the upper horizontal wire. When closed, a portion of the U-shaped door slides in front of and is then bent under a wire disposed below the door frame; it thus travels downward, being engaged in an entrapment below the door to restrict its sideward movement.
