SACK PACKER Russian patent published in 1995 - IPC

FIELD: packing facilities. SUBSTANCE: sacks are delivered by pusher to gate platform 5 where layer is formed. After collecting a layer, platform 5 starts moving rearwards. Support 11 can roll over main upper and additional lower branches of guide switch. With platform 5 moving backwards, support rolls over lower branch of switch and as a result, turning plate 13 lowers and roller 14, rolling on sacks placed below, eliminates deformation of sack caused by action of pusher. With gate platform 5 moving forward, support 11 rolls over upper branch of guide switch without engagement with sacks. EFFECT: enhanced reliability of operation. 6 dwg
