Box end labeling apparatus

Claim 1

A machine for simultaneously overlabeling both ends of a box of parallelipiped configuration, said machine comprising: a processing way having entrance and exit ends, means for conveying the box to be labeled longitudinally of said way including means for disposing the box to extend transversely of said way whereby the box ends project to either side of said conveying means, said way including a labeling station and a label folding station in spaced apart relation therealong, a label supply station for each box end and means for feeding a label from the respective label supply stations to said labeling station, said label supply stations and said label feeding means for each box end being located relative to said conveying means to dispose the labels for each box end to have one end of same projecting toward the way and underlying the path of movement that the box end to be labeled thereby has when the box is moved along said way by said conveying means, and to have the other end of same project laterally of said way and said path endwise of the box end and away from said way and beyond said path, whereby the labels for each box end extend transversely of said way, said labeling station including means for applying glue to the underside of the respective labels when received from said label supply station and means for rolling the respective said one ends of the respective labels onto the underside of the box at either end of same as the box is moved through said labeling station, said label folding station including means for consecutively wiping the respective labels flush against said box ends for adhering same thereto, and for wiping the labels flush against the top side of the box for adhering same thereto, said means for wiping the respective labels flush against said box ends comprising for each box end comprising: a vertically movable wiping member mounted for reciprocating movement between a retracted position below the level of said paths to an elevated position projecting above the level of said paths, said label folding station further including for each wiping member a generally planar pressure panel disposed vertically and paralleling said way, said panels being respectively mounted and positioned in vertical alignment with and beneath the respective paths of movement of the respective box ends and defining rectilinear top edges horizontally disposed and substantially aligned with the level of the underside of the box when the box is positioned at said label folding station between said panels, said wiping members each including a resiliently compressible pad defining a sliding wiping surface disposed to bear compressively against the respective panels when said wiping members are in their retracted positions, and to bear compressively against the respective box ends when said wiping members are in their elevated positions, means for moving said wiping members between their said positions for slide wiping the respective labels flush against said box ends when the box is at said label folding station, means for holding the box that is at said label folding station against vertical movement on movement of said wiping members to their said elevated positions, said means for wiping the respective labels flush against the top side of the respective boxes at said label folding station comprising for each box end to be labeled: a horizontally movable roller mounted for reciprocating movement in a plane level with the level of the top sides of the boxes, as they are disposed along the path of movement of the respective box ends, between a retracted position to one side of the way and an extended position overlying the way wherein said rollers ride on the top sides of the respective boxes when at said label folding station, and means for reciprocating said rollers between said positions for wiping the respective labels against the top sides of the respective boxes.
