Articles are moved in closest packing formation through the staging area over a deadplate toward one of a plurality of containers moving in a generally linear direction parallel to a carton line. An angle of approximately 60° between the staging area and a container in position for receiving articles orients a row of articles in closest packing formation parallel with the open front end of that container. As articles enter the container, each row of articles rolls over the previous row, causing articles to be arranged in a rectangular array in the container. When the container is filled with articles, flow of articles stops and a bar is engaged to clamp a row of articles adjacent to the filled container between the bar and the deadplate. The back of the container is moved away from the articles therein to allow the last row of articles in the full container to pass by articles constrained by the bar without scratching or otherwise damaging the articles when the filled container is moved. The filled container is moved away from the clamped articles, an empty container is moved into position to receive articles, and the bar is disengaged to allow articles to flow into the container. Articles in the container are subsequently loaded into a carton on the carton line.Field of SearchHaving items discharged from plural distinct outlets into groupWith outlets longitudinally spaced along path of progressively formed group Superposes items within group By depositing items successively from one conveyor onto group conveyor By shifting group from row conveyor onto row conveyor By shifting group from row conveyor onto stream conveyor With means to supply successive receptacles Contents or receptacle transfer between conveyers By reciprocable pusher Stacking upon another before packaging Single layer forming Receptacle advances as row groups are deposited therein Forming single generally horizontal groups comprising plural rows and columns Stacking one article or group of articles upon another Horizontally loaded box or carton | |
