Abstract: An apparatus for conveying an article through a hot air chamber of a shrink packaging machine comprises a first conveyor and a second conveyor. Each conveyor includes a plurality of rollers. The rollers of the plurality are interconnected together to form an endless conveyor belt. The conveyor further includes a drive assembly for advancing the endless conveyor belt in a first direction, and a track member having a surface disposed in engagement with particular rollers of the endless conveyor belt. Each of the particular rollers of the endless conveyor belt rolls over the surface of the track member when advanced through the shrink packaging machine. The first conveyor is located over the second conveyor in opposing facing relation therewith such that a compressible item to be shrink wrapped may be compressed and conveyed through the shrink packaging machine between and by the first and second conveyors.

Abstract: A method for accommodating a greater height variance of articles in a shrink packaging machine includes: transporting on a conveyor into a hot air chamber an article covered in shrink film and engaging the article being transported on the conveyor with a first roller and a subsequent second roller. The article is engaged with the first roller at a first initial vertical height from the conveyor that is less than the initial vertical height of an axis of rotation of the first roller from the conveyor. The article is engaged with the second roller at a second initial vertical height from the conveyor that is less than the initial vertical height of an axis of rotation of the second roller from the conveyor, which in turn is less than the initial vertical height of the axis of rotation of the first roller from the conveyor.

Abstract: A shrink packaging machine for shrink wrapping an article with shrink film includes: a hot air chamber; a conveyor operable to transport the article covered by shrink film at least partially through the hot air chamber; a first roller disposed over the conveyor and configured to engage the article transported on the conveyor; and a plurality of additional rollers disposed over the conveyor. Each of the plurality of additional rollers is vertically displaceable relative to the conveyor independent of displacement of the other of the plurality of additional rollers. Furthermore, when each of the plurality of additional rollers is in a respective lowermost position relative to the conveyor, an axis of rotation of the first roller is disposed at a height from the conveyor that is greater than a respective height from the conveyor at which each axis of rotation of each of the plurality of additional rollers is disposed.

Abstract: An apparatus for use in a shrink packaging machine for accommodating a greater height variance of articles includes: rollers, each roller including a shaft and a cylinder on the shaft for rotation about an axis of the shaft; and a frame including a pair of parallel side members generally extending in a first, horizontal direction and defining slots receiving opposite ends of the shafts for mounting of the rollers there between. Each of the slots has a slot length that extends in horizontal and vertical directions, and the rollers each generally extends in a third direction orthogonal both to the horizontal and vertical directions. Furthermore, each of the rollers is received within a pair of the slots and is vertically and horizontally displaceable and, when each roller is disposed at its respective lowermost position, the axes of the rollers do not all lie within a horizontal plane.
