Abstract:
The conveyor system is comprised of a plurality of spools connected by chains at each end of the spool. The space between an adjacent pair of spools defines a pocket. An ejector is carried by the chain within each pocket to eject fruit from the pocket. The ejectors are selectively activated by solenoids lying underneath the chain and mounted on a conveyor channel across which the chain and spools are pulled. A photooptical detector is provided for detecting when an ejector is missing due to damage or other loss. A system control circuit detects the missing ejector and stops the conveyor at a predetermined position so that the missing ejector stops at a predetermined repair location on the conveyor system.
Abstract:
An apparatus for measuring and recording accelerations or other physical quantities experienced by easily damaged items of commerce such as fruit and electronic computers. A triaxial accelerometer or other suitable sensor produces signals which are sampled by a microprocessor operating according to a program stored in a read-only memory. When the sampled accelerations or other physical quantities exceed a predetermined threshold, samples are stored in a random access memory, along with their times of occurrence. The apparatus provides a serial port for reading out the recorded acceleration data. The data may then be subjected to further processing externally.
Abstract:
Fruit or other objects placed on the conveyor and spun by the conveyor are properly oriented on the conveyor by the method and apparatus of the invention by ejecting one or more adjacent touching objects or ejecting objects which form stacked triplets. An optical sensor determines when there is or is not a gap between objects and relates that gap detection to the position of the objects on the conveyor. Detection of a continuous signal through a controller circuit causes a downstream solenoid to be energized according to predetermined timing. The solenoid in turn, when energized, rotates a finger which is coupled to, carried with the conveyor system and situated underneath the pocket between adjacent spools. The finger rotates upwardly and ejects the objects sitting in the pocket, thereby removing the misplaced or touching objects on the conveyor belt.
Abstract:
The instant invention pertains to ascertaining the condition (i.e. texture, maturity and extent of damage (if any)) of an agricultural commodity by: (a) inputting band-limited vibrations (i.e. limited to a specific frequency band); (b) sensing vibrational characteristics (e.g. energy, resonance, absorption frequency characteristics) resulting from the input vibrations, and; (c) analyzing the vibrational characteristics.
Abstract:
The present invention relates to a melon cutting apparatus that cuts a melon portion or melon half. The apparatus cuts the melon pulp into sections, and removes the rind from the pulp. The apparatus includes a base having an opening; a cutting matrix that has a plurality of blades, wherein the cutting matrix communicates with the opening. The apparatus also includes a sweeping blade that is curved and positioned at or near the cutting matrix and is used to cut the rind from the melon pulp. The apparatus further includes an actuator that engages the sweeping blade. The apparatus embodies an arm attached to the apparatus, and a pressure cap that is mounted to the arm, opposite the cutting matrix. Additionally, the present invention pertains to systems and methods of using the apparatus.
Abstract:
The topographic surface features of a translucent object, such as a citrus fruit with a peel, are scanned and evaluated to permit the classification thereof according to its surface features. In the case of citrus fruit, the coarseness or pebbliness, puff and crease, ridge and valley, cuts, punctures, scrapes and splits, clear rot or sour rot of the peel is optically identified through digital analysis of the pixel scans and sorted based upon the peel surface quality. The object is classified by separating the scanned image of the fruit from the background image and removing the background image. A statistical evaluation of the image of the object as a whole, including both hemispheres of the object, is made to determine if there is any surface feature variation which might qualify as a defect or be a suitable basis upon which a classification judgment can be made. If there is, the object image is subject to high frequency or low pass filtering and thresholding of the pixel intensities to derive a refined image. The refined image is then tabulated or organized into neighborhoods contiguous to sharp transitions or gradual transitions to identify specific areas defined as blobs which, when compared against a given minimum area, shape requirement and/or width can be identified as one of the surface imperfections sought.
Abstract:
Application of wax to fruit, or groups of fruit in a conveyor system, can be controlled to optimize the protective and cosmetic effects of the wax application and to efficiently utilize the wax notwithstanding variations in size, texture, nature or number of the fruit, the type(s) of wax or the processing environment, by providing an intelligent wax controller. The wax controller has a camera which detects fruit passing through a field of view defined by an optical housing in which the camera is fixed. Particularly if the camera is a line-scan camera, two-dimensional pixel maps of the fruit passing through the viewing area are assembled and image processed to provide distinct pixel images even when the fruit are touching. The entire width of the conveyor belt is detected furing each detection time. The diameter of the fruit for each of the separated images is then determined, from which the total surface area of the fruit passing under the viewing area is computed. Based on this computation a plurality of variable stroke pujps and wax nozzles are each individually controlled at appropriate positions across the width of the conveyor system to apply the appropriate amount of wax to the fruit then passing under the wax applicator nozzles.
Abstract:
The conveyor system is made of a plurality of spools connected by chains at each end of the spool. The space between an adjacent pair of spools defines a pocket. An ejector is carried by the chain within each pocket to eject fruit from the pocket. The ejectors are selectively activated by solenoids lying underneath the chain and mounted on a conveyor channel across which the chain and spools are pulled. During operation, chain stretch is measured between two sensors at each end of the conveyor system. When the stretch has exceeded a predetermined limit, a warning signal is generated and the conveyor system can be stopped to allow appropriate repositioning of the solenoid assemblies for activating the ejectors or the timing of the firing of the ejectors automatically readjusted by software control.
Abstract:
An improved actuating system for a plurality of tucker plates used to compress and tuck arrays of fruit placed by an automated fruit handler into shipping cartons is described. The timing and motive force used for operation of the tucker plate is derived from motion of the fruit handler. Contact of the fruit and the fruit handler with an inclined tucker plate on each of four side is sufficient to cause tucker plates to rotate about a hinge assembly which couples the tucker plate to the packer table through which the fruit handler disposes the layers of fruit into the shipping cartons positioned on a conveyor underneath the packer table. Each tucker plate is provided with an upper finger which contacts the fruit handler as the fruit handler move upwardly thereby causing a torque to be applied to the tucker plate to reorient the tucker plate from the vertical packing position to an open tilted receiving position.
Abstract:
An automatic food product cutting apparatus is provided that employs a continuously rotating table arranged with multiple cutter cups, each cup being aligned with a plunger that rotates with the table. The plungers are driven to force fruit through the cup and to withdraw from the cup by cam following rollers that follow a generally elliptical cam track. The cam track is concentric to but does not rotate with the table. With this arrangement, a single drive motor is used to power both the rotation of the table and the plunging force to push the food product through the cutter cups, thereby achieving smooth, continuous operation.
