Patent number: 11440055Abstract: Embodiments of the disclosure can relate to systems and methods for sorting balls. The systems and methods may involve the use of a ball-feeding mechanism for receiving one or more balls, and feeding the one or more balls to a projection element. The projection element may be located beneath the ball-feeding mechanism such that the balls drop from the ball-feeding mechanism to the projection element, and the balls then project from the projection element to a ball-sorting apparatus. The balls may then subsequently be sorted into a sorting container of one or more sorting containers based on the projected height of the ball.Type: GrantFiled: December 4, 2020Date of Patent: September 13, 2022Inventor: William Vaughn Jenkins

Patent number: 7975853Abstract: The invention relates to the high speed non-destructive sorting of small food items for softness. The food item is conveyed on a series of belts designed to accurately drop the food item onto a flexible surface at an oblique angle. Accelerometers mounted under the flexible surface generate impact waveforms, which are computer analysed to both detect the item landing position and enable comparison with an operator-selected softness threshold level. Within a few milliseconds of the food item contacting the flexible surface it continues to drop past a rejection point. If determined by analysis to be soft, it is ejected to a waste conveyor.Type: GrantFiled: July 3, 2006Date of Patent: July 12, 2011Inventor: Gregory William Furniss

Patent number: 5301816Abstract: A new separating method and a corresponding apparatus and the use of the apparatus for the environmentally sound separation of different material mixtures, are disclosed wherein, in addition to dynamic forces, the area pressure between the bodies to be sorted and an inwardly elastic sorting drum are made of use. Bodies which are heavy with respect to specific area pressure sink into the interior of the drum and are thrown out at a lower location. Parts which are light with respect to specific area pressure, on the other hand, are rejected from the surface of the drum and guided away separately. In so doing, the device achieves very efficient separation. The invention is particularly effective for the separation of reclaimable material mixtures, so-called "recyclables", particularly with respect to fractions such as liftings which are otherwise difficult to separate.Type: GrantFiled: August 17, 1992Date of Patent: April 12, 1994Assignee: Buehler AGInventors: Heinrich Weber, Falko Lehrmann, Clemens Weibel

Patent number: 4311241Abstract: Method for separating clods and the like from potatoes, which includes placing the clods and potatoes on a first belt for transporting the potatoes and clods toward a forward end and positioning a second belt spaced horizontally apart from and vertically lower than the end of the first belt such that potatoes leaving the end travel through the air and land on the second belt. The clods are detected by a detector that includes a magnet and a coil positioned in the field of the magnet. The clods are removed from the system by a normally flaccid inflatable finger positioned between the forward end of the first belt and the second belt. When the detector signals the presence of a clod, air is supplied to the finger causing the stiffening thereof, which deflects the trajectory of the clod causing it to fall between the forward end and the second belt.Type: GrantFiled: November 13, 1979Date of Patent: January 19, 1982Assignee: Lockwood CorporationInventors: F.

Patent number: 4281766Abstract: To sort first bodies from a mixture of first and second bodies in which the first bodies, for example potatoes or other root crop, are less dense than the second bodies, for example stones harvested simultaneously with the root crop, the mixture is dropped down a vertical pathway onto an energy absorber. This comprises spaced resilient strips disposed side by side in a common plane transverse to the vertical. The impact of the denser second bodies bends the strips down sufficiently to allow the second bodies to continue along the pathway past the energy absorber. But the less dense first bodies only bend the strips to a lesser extent and are halted thereby. On resiling the strips flick such halted first bodies from the pathway.Type: GrantFiled: December 3, 1979Date of Patent: August 4, 1981Inventor: Alan Constantine

Patent number: 4267930Abstract: A batch of raisins in which moldy raisins are mixed with sound ones is immersed in a hot water bath, causing the moldy raisins to assume a mushy and sticky texture while leaving the texture of the sound raisins substantially unaffected. The batch of raisins is then dropped onto a laterally inclined conveyor belt. The conveyor belt moves the raisins over a framework which is rapidly moved up and down to slap the underside of the belt, causing the raisins to bounce up and down on the continuously moving conveyor. The sound raisins, which have retained their firm texture, are bounced substantially higher than the moldy raisins, and thus, bounce down off the side of the conveyor as they move along the length of the conveyor. Because of their mushy texture, the moldy raisins do not bounce as high as the sound ones and therefore do not as readily bounce downward off the conveyor. Instead, they are carried along and off the end of the conveyor.Type: GrantFiled: February 28, 1979Date of Patent: May 19, 1981Assignees: Douglas H. Melkonian, Mark S. Melkonian, Dennis J.
