Apparatus for grouping of packages

An apparatus for grouping packages, comprising:

• horizontal delivery means composed of upper and lower transfer belts for sequential high speed delivery of the packages;
• vertical conveyor means disposed for receiving the individual packages from said horizontal delivery means, conveying the individual packages vertically and arranging the individual packages in groups for transfer to a horizontal output device, wherein said vertical conveyor means comprise two parallel-extending endless belts and a plurality of parallel rows of brushes carried by each said belt and disposed for engaging each individual package received by said vertical conveyor means from below and supporting each individual package as it is being conveyed vertically;
• a horizontal bottom plate disposed at the lower end of said vertical conveyor means for receiving the individual packages conveyed by said conveyor means until successive packages are stacked to form one package group;
• a pusher displaceable parallel to the plane of said bottom plate and between said endless belts for transferring each package group to the horizontal output device, said pusher having a horizontally extending upper portion located above, and spaced vertically from said bottom plate for temporary storage and pre-grouping of packages conveyed by said vertical conveyor means;
• and a light barrier connected to control the operation of said pusher and disposed at a height above said bottom plate that corresponds to the desired height of one package group.
