Abstract
A bag filling and packaging apparatus including hollow guide members that are disposed below ascending/descending hoppers and guide product dropping from hoppers into the interior of bags, the guide members being raised/lowered and moved together with the hoppers in a filling region. The guide members comprise a pair of opening and closing guide frames that are disposed to face each other; and when clogging is detected in a guide member, its guide frames are repeatedly opened and closed while moving through a non-filling region, thus promoting the dropping of product. Directly below the guide members is provided a receiving member that receives the product.
