Device for stacking batches of flat objects in a vertical file

In a piling device for flat objects arranged batchwise, especially folded boxes of corrugated board or non-folded blanks of boxes arranged in successive layers on any sort of loading plane, said device including a frame containing infeed means for conveying the batches into the device on a conveying axis, means for carrying a layer of batches from the infeed means to a point above a vertically movable loading plane, means for retaining and then laying down the layer on top of said loading plane, means for laterally guiding of the layer as the layer is being laid down onto the loading plane, stop means for positioning a front edge of each layer in said means for carrying and means for vertically shifting said loading plane, the improvements comprising said infeed means for the batches being made up of a table having motor-driven rollers with axles, said rollers cooperating with a lateral baffle arranged at right angles to the axles of said motor-driven rollers, said means for carrying a layer of batches to a point above the vertical moving loading plane consisting of two rows of spaced apart motor-driven, vertically arranged rollers for engaging opposite sides of the layer to be carried forward, mounting means for adjustably positioning said two rows in said frame laterally to said conveying axis, said mounting means including two supporting bars being movable in the frame by a setting appliance, a longitudinal beam for mounting each row of rollers, each beam being connected by air cylinders to one of said supporting bars to move therewith, said means for retaining and then putting down said layer including a retaining appliance operating jointly with each vertically arranged roller and a support operating jointly with said two rows, said means for laterally guiding said layer consisting of vertical batch guides being mounted on said supporting bars to extend within spaces existing between the vertically arranged rollers of said rows, said stop means comprising a front stop plate having an adjustable size as required by the size of said batch, and said lateral baffle being secured to an extension of one of said rows situated on the side of the conveying axis.
