Abstract
Abstract A mechanism to accept containerized product, particularly frozen potato products in flexible bags, in an unordered fashion, accumulate the product in vertical array and positively deposit the amassed array in a container. A slower conveyor presents bagged product to a faster pivotably mounted conveyor which deposits the product successively on vertically spaced accumulator plates that are moved toward each other to compact the array of product between adjacent plates; the compacted product is then moved horizontally into a pre-positioned container which is removed for closure and further processing.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
181 words
A product accumulator and boxer of the nature aforesaid including, in combination: an imput conveyor having associated means of product agitation to transport supported product to; an adjacent elongate accumulator conveyor pivotably mounted in its forward product receiving part on an accumulator frame for vertical motion of its rearward part, the accumulator conveyor having associated means of vertically moving its rearward part to plural, spaced, pre-determined positions; an accuMulator structure, supported by the accumulator frame, having plural vertically spaced accumulator plates immediately rearwardly adjacent the rearward part of the accumulator conveyor to receive product therefrom, each of the accumulator plates being carried by mechanical supported linkage by the accumulator frame each said linkage operable to move a plate relatively closer to an adjacent plate during vertical downward motion to compress product supported upon the plates; a pusher arm structure adapted to push product horizontally from the accumulator plates into a boxer structure defining a product channel to receive the vertically stacked product and move it horizontally into a prepositioned container for further processing; and motive means to activate the several members.
Claim 2
Dependent Claim
181 words
A product accumulator and boxer of the nature aforesaid including, in combination: an imput conveyor having associated means of product agitation to transport supported product to; an adjacent elongate accumulator conveyor pivotably mounted in its forward product receiving part on an accumulator frame for vertical motion of its rearward part, the accumulator conveyor having associated means of vertically moving its rearward part to plural, spaced, pre-determined positions; an accuMulator structure, supported by the accumulator frame, having plural vertically spaced accumulator plates immediately rearwardly adjacent the rearward part of the accumulator conveyor to receive product therefrom, each of the accumulator plates being carried by mechanical supported linkage by the accumulator frame each said linkage operable to move a plate relatively closer to an adjacent plate during vertical downward motion to compress product supported upon the plates; a pusher arm structure adapted to push product horizontally from the accumulator plates into a boxer structure defining a product channel to receive the vertically stacked product and move it horizontally into a prepositioned container for further processing; and motive means to activate the several members.
Claim 3
Dependent Claim
31 words
The invention of claim 1 wherein the accumulator conveyor has a greater conveyor speed than the imput conveyor to space product along the accumulator conveyor and prevent its accumulation or fouling.
Claim 4
Dependent Claim
105 words
The invention of claim 1 wherein the mechanical linkage communicating between the accumulator plates and the accumulator frame is further characterized by: plural vertically spaced conveyor arms extending perpendicularly from each accumulator plate to spaced pivotable mounting in the end parts upon an auxiliary frame supported by the principal accumulator frame, each accumulator plate having; a pivotably mounted cog in its proximate end part structurally carrying the associated accumulator plate with a chain communicating about the cog having each of its ends rigidly fastened at approximately the pivot point of said arm to allow the accumulator plates to move toward each other and remain parallel.
Claim 5
Dependent Claim
67 words
The invention of claim 3 further characterized by the accumulator plate end of the accumulator plate arms being supported upon plural rollers carried in vertically spaced array by an accumulator plate arm lever pivotably mounted in its lowermost portion upon the accumulator frame; and means of pivotably moving the accumulator plate arm lever away from the vertical to allow the accumulator plate arms to move closer together.
Claim 6
Dependent Claim
47 words
The invention of claim 1 wherein the accumulator conveyor is biased downwardly by hydraulic means communicating from the conveyor frame to the principal accumulator frame and is adjustably restrained from motion by pneumatic means extending between the same elements to provide fine control of accumulator conveyor motion.
