  • Patent number: 4258532
    Abstract: An arrangement for the feeding of objects to and grouping them on a base.In order to simplify handling and transport of milk packages it is frequent to use transport packages in the form of trays or the like, onto which a number of milk packages are placed in close stacking. For this purpose automatic machinery is used, which machinery automatically loads the milk packages on a transport package placed in position for loading. In order to avoid interruptions when an empty transport package has to be substituted for a filled one this invention suggests an arrangement according to which the milk packages are first collected in close stacking on a pre-loading surface. Thereafter, when the new transport package has been brought in correct position adjacent to the pre-loading surface, the collected milk packages are transferred onto the transport package.
