Patent number: 5483871Abstract: Described is an apparatus and method, particularly applicable to a brush bed conveyor system, by which objects, typically citrus fruit, are washed or sprayed. A moveable high pressure spray manifold is contained within a manifold carriage and is disposed within the conveyor chassis such that it is moved along above a brush bed by a conveyor chain. Separation bars extend from the conveyor chain to segregate the objects into queues retained within the spray pattern of the manifold. When the manifold reaches a predetermined end position, a release latch is decoupled from the separation bars to disconnect the separation bars and conveyor chain from the manifold carriage. The predetermined end position is sensed and the manifold carriage is quickly returned to its initial position by means of a selectively activated pneumatic piston assembly.Type: GrantFiled: February 24, 1994Date of Patent: January 16, 1996Assignee: Sunkist Growers, Inc.Inventors: William Kirk, Henry A.

Patent number: 5482154Abstract: 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.Type: GrantFiled: September 26, 1994Date of Patent: January 9, 1996Assignee: Sunkist Growers, Inc.Inventors: Henry A.

Patent number: 5457933Abstract: 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.Type: GrantFiled: February 24, 1994Date of Patent: October 17, 1995Assignee: Sunkist Growers, Inc.Inventors: Everett LaVars, Henry A.

Patent number: 5164795Abstract: A method and apparatus is disclosed for grading the surface of generally apherical fruit according to surface characteristics such as color and blemish. The fruit are moved in single file past a scanning camera while being rotated about a transverse horizontal axis. Reflectivity data in three separate wavelength bands is collected for a series of scans of each article of fruit, and this data is processed to eliminate all duplicative data arising from the fruit's rotation. Color ratio signals based on the remaining reflectivity data are then utilized to grade the fruit according to their surface color and degree of blemish.Type: GrantFiled: March 23, 1990Date of Patent: November 17, 1992Assignee: Sunkist Growers, Inc.Inventor: Tim D.

Patent number: 5148738Abstract: A method and apparatus are disclosed for treating fresh fruit to prevent and retard the growth of fungus. The techniques of the invention include simultaneously scrubbing the fresh fruit while drenching with a falling liquid containing a fungicide. Large volumes of liquid are used and the liquid can be recycled. The liquid also removes dirt and debris and, while containing a rather small amount of fungicide, such amount is present in a concentration sufficient to apply a coating to the fruit at the end of the scrubbing step given proper pH control. The pH of the solution is controlled. During the scrubbing step, the fruit is continuously rotated to provide even fungicidal deposit.Type: GrantFiled: October 11, 1991Date of Patent: September 22, 1992Assignee: Sunkist Growers, Inc.Inventors: Charles R.

Patent number: 5000967Abstract: An improved process for preparing individual fruit sections from fresh citrus fruit, with improved ease of peeling and sectioning and with reduced amounts of adhering albedo. The fresh citrus fruit are initially scored so as to penetrate the albedo layer, but not the underlying juice sections, and the scored fruit is then immersed in an aqueous solution of a pectinase enzyme. A series of positive pressure pulses is applied to the immersed fruit, to infuse the enzyme solution into the albedo and, after storing the infusion-treated fruit for a prescribed time period, the peel and other membrane material can be readily removed from the fruit and the individual fruit segments readily separated from each other. Infusing the pectinase enzyme solution under pressure, rather than vacuum, and maintaining the solution at approximately room temperature, rather than an elevated temperature, significantly improves the ease of peeling and sectioning and reduces the amount of adhering albedo.Type: GrantFiled: April 19, 1989Date of Patent: March 19, 1991Assignee: Sunkist Growers, Inc.Inventors: Bruce Adams, William Kirk
