Abstract:
An article weighing machine having a turntable with fixed rakes for directing articles, i.e., fruits or vegetables, on the turntable along prescribed paths into side-by-side metering assemblies where successive articles are placed in successive pockets formed by opposed fingers on continuous chains, the fingers moving in linear parallel paths above cooperating parallel feed belts. Brushes over the entrance and exit of each assembly engages each article as it enters and leaves the fingers. The parallel belts receive the successive, equally spaced articles thereon and transport them successively to weighing cells where such articles are individually weighed and analog signals corresponding to the weight of the individual article are fed to a control logic which then converts such signals to digital form and transfers the logic output to a computer. The speed of the feed belt is also fed to the computer which signals as a function of the weight the opening of a selected air nozzle, of a series of longitudinally spaced air nozzles, when the individual article has been transported to the vicinity of such air nozzle, whereby the air blows the article laterally off of the belt and onto a discharge belt, feeding to a container positioned by a container conveyor to receive the articles. When the computer totals the appropriate weight for a given container, the conveyor is indexed.
Abstract:
A flow control or flow diverging gate assembly for a conveyor having a sidewall interrupted by an opening along its length, a flow diverting gate or shear being pivotably mounted in the opening and extendable and retractable in length, the unpivoted end of the gate being guided by track means including a first guide portion parallel with the sidewall and second guide portion traversing the conveyor, movement of the gate along the first guide portion providing a variable opening in the side wall to relieve overflow on the belt, movement of the gate along the second guide portion intercepting a portion of the flow path along the conveyor to selectively reduce the flow of articles therealong.
Abstract:
This invention relates to an apple orienting device suited to orient apples particularly those known as the Red Delicious variety and which are generally relatively long as compared to their diameter. The present orientor includes a pair of eccentrically mounted wheels, and represents an improvement over presently known devices. The orienter uses two eccentrically mounted wheels to aid in orienting the apples.
Abstract:
A bin filling mechanism comprising an inner frame mounted for oscillation about an intermediate frame and carrying a pivotally mounted product conveying means thereon. The intermediate frame is vertically adjustable with respect to a main frame to allow adaptation of the device to variously sized feed mechanisms. A sensing means of the bin end of the product conveying means initiates raising of the product conveying means as the bin is filled with product. A slotted disc and rod arrangement provides for oscillation of the whole inner frame structure to insure even distribution of product within the bin.
Abstract:
A high capacity device for reliably sorting pieces of fruit from a bulk supply into individual cups for processing. The fruit is received in bulk in a hopper, a side of which is open to a center hub of a connected pair of feed wheels revolving coaxially in spaced horizontal relation. Each feed wheel carries a plurality of radially-extending through passages about its periphery. Each passage carries at least two individual pieces of said fruit simultaneously. An outward, exit end of each passage is normally blocked by cammable gate fingers. The feed wheels are rotatably synchronized with a pair of chains engaged with sprockets attached to the feed wheels and carrying therebetween a conveyor carrying the fruit cups. The speed of revolution of the feed wheels is sufficient to keep an outermost one of the fruit pieces lodged adjacent the gate fingers. Fixed camming surfaces open the gate fingers of each feed passage at a tangential engagement point between the wheel sprockets and the drive chain of the conveyor, thereby to place the outermost fruit from each passage gently into the receiving cup.
Abstract:
A peduncled vegetable and fruit positioning device has an endless conveyorrain formed by pairs of rollers moving in the same direction, the rollers being axially parallelly arranged. One of the pairs of rollers has one or more peripheral canals and a radial blade while the other roller is hyperboloid or has a surface provided with one or various canals. The fruit coming from a feeder is deposited between each two rollers. A conveyor train has upper walls transverse to the displacement of the rollers, which walls separate each pair of rollers from the next, preventing the fruit from passing from one zone to the adjacent zone, so that the fruit deposited between two rollers turns due to contact therewith until the pedicle of the fruit is housed between the two rollers and extends in a vertical position between the rollers, so that the fruit finally rests on the outer surface of both rollers.
Abstract:
A continuously driven belt conveyor transports and accumulates articles supported thereon. Ways are positioned alongside the conveyor belt and are movable to vary the relative vertical position of the ways between an accumulation position wherein the support surface of the ways is above the conveyor belt causing the articles to accumulate and a drive position wherein the support surface of the ways is below the conveyor belt to permit movement of the articles therealong. Preferably, the ways are moved vertically by elongated inflatable tubes which lift the ways together with the articles above the moving conveyor surface.
Abstract:
A continuously running single-row conveyor delivers N number of objects in a time period T. A shuttle reciprocating at the rate of one reciprocation per T, accelerates in the direction of travel of the conveyor to drop a row of N objects onto the conveyor. The shuttle is reciprocated by a continuously driven epicyclic train that causes the shuttle to pause at its starting position. A cyclic loader replenishes the shuttle at the starting position and, in turn, is replenished by supply means that organizes a bulk supply of the objects into N parallel travelling rows with the objects in the parallel longitudinal rows forming transverse rows of N objects each. The supply means operates step by step to deliver the successive transverse rows of N objects to the cyclic loader.
Abstract:
A conveyor is disclosed which effects longitudinal separation of a single file of articles fed thereto in abutting relation. Separation is effected by providing conveyor sections comprising at least two non-powered rollers straddled by powered rollers rotating to retain the article on the non-powered rollers. The conveyor structure also lends itself to handle multiple files of articles, articles which vary in length, height and width, and articles which are fragile and easily damaged.
Abstract:
An unloading bin having an open top and front is rotatably supported about its center on a frame above an open topped hopper. The bin is rotatable about a horizontal axis centered with respect to the bin at selected rates from a ''''top-up'''' position to an inverted ''''bottom-up'''' position. An open-topped parts container is positionable in the bin through the open front and tilted rearwardly to empty the parts into the hopper by gradual rotation of the bin. Rods across the top of the bin prevent the container from falling out. In a preferred arrangement, the hopper is positioned above a conveyor which receives and removes the parts as they are fed through the hopper. A sensor associated with the conveyor controls the rate of tilt of the bin to control the rate of emptying.
