Abstract: An egg carrier including a gripper mechanism wherein the egg carrier is operative to grip and release an egg at a predetermined orientation. Accordingly, the egg carrier includes a mechanism whereby the gripper mechanism can be rotated whereby an egg can be released at an angle greater or less than 90°. The gripper mechanism capable of gripping an egg in one orientation and then pivoting or changing the orientation of the egg such that the egg is released at a predetermined angle.

Abstract: An egg orientation mechanism orients eggs within an egg handling machine including a plurality of randomly arranged eggs on a first egg conveying mechanism. A lifter mechanism located on the first egg conveying mechanism raises each egg away from the egg conveying mechanism to off balance and rotate the egg so that the egg is oriented to with larger end of egg leading as egg is released into a second egg conveying mechanism. A clamshell egg receiver includes a front wall, a rear wall and egg receiving space formed between front wall and the rear wall. Either one of front wall or rear wall pivots about a pivot point located below a centerline of the egg receiving space. A method of releasing an egg includes holding an egg by an egg holder, rotating the egg holder and releasing the egg at an angle greater or less than 90 degrees.

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.

Abstract: An egg packing apparatus includes an endless conveyor including a plurality of rotatable parallel rollers each provided with a plurality of abutments in the form of annular flanges. The flanges of any one roller are aligned with flanges on other rollers to form a plurality of transport channels or feed paths extending to respective guide chutes. The guide chutes are each defined by a pair of opposing side walls, a pivotably mounted plate member and an additional wall opposite the plate member 36, the additional wall being provided with a V-shaped portion extending inwardly towards the plate member so that the guide chute has a decreased width in a central region. Upon the deposition of an egg on the plate member with the narrow end of the egg is contact with one of the side walls of the guide chute, the plate member is pivoted and the large end of the egg is temporarily held between the additional wall and the plate member, allowing the narrow end of the egg to swing downwardly.

Abstract: An article coding and separating system such as for instance, in which articles or defective eggs which are randomly dispersed in a plurality of similar articles are coded and their location identified. An elongated pivotally mounted pointer is disposed so as to be pivotable over an inspection area in mutually orthogonal directions, parallel and transverse to the longitudinal axis of a conveyor, and axially movable towards and away from the articles being conveyed. 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: An apparatus for transferring individual trays of eggs from the top of adjacently spaced stacks onto a conveyor member. A lifting head is provided for each stack of egg trays and includes thereon vacuum cups which are engagable with each of the individual eggs in the uppermost tray. A vacuum actuated gripper is further provided with each lifting head assembly for engaging and lifting the uppermost tray away from the remainder of the stack. Each lifting head assembly is associated with a rotatable drive to effect rotation during transfer while also moving adjacently spaced lifting head assemblies with respect to one another in order to avoid contact during simultaneous rotation of adjacent lifting head assemblies. Relative movement between each head assembly and the respective support platform is also provided to accommodate variations in height between adjacent stacks to insure proper engagement with the uppermost tray to be transferred.

Abstract: A band saw machine is provided with a cutting head that carries the endless saw blade. The cutting head can be swung from a vertical cutting plane into a horizontal cutting plane. Limits can be made in the feeding stroke of the cut and the return travel. A workpiece feeding and clamping vice is rotated about a horizontal axis. The combined positioning capability of the band saw blade and the workpiece vice allows difficult compound angular cuts to be made in the workpiece. The endless run of the blade is angled upwardly and outwardly away from the workpiece to provide additional clearance for cutting deep workpieces. Powered feed rolls advance the workpiece against a gauging stop to determine a predetermined length to be cut. The vice is then closed to hold the workpiece during cutting. Supplemental supports hold the rearward end of the workpiece during feeding and cutting. Blade guides are spaced for accomodating both small and large width blades.
