Abstract
Method and device for packing bags filled with product in a box. The bags are made gas-permeable and after the bags have been filled with product the residual volume of gas therein is removed by drawing off the gases present in the bag by means of suction. This is achieved by conveying the bags over a belt on which vacuum is acting. Prior to this step the bags can be subjected to a vibratory treatment in order to optimise the position of the product in the bags.
Claims12
Method for packing products, comprising introducing said products into a gas-permeable flexible packaging, closing said flexible packagings and placing a number of flexible packagings in an outer packaging, wherein, after closing said flexible packagings and before placing them in said outer packaging, the residual gas volume in said flexible packaging is reduced, wherein said flexible packagings are placed on a support and means generating a vacuum are placed on the gas-permeable part of said flexible packagings in order to reduce the volume of said flexible packagings.
Device for packing products, comprising a feed for products, a feed for gas-permeable film material, means for producing bags from said film material, filling means for introducing products from said feed into said bags, closing and separating means for closing and separating said bags, vibratory means for reducing the volume of said closed bags, vacuum-generating means for applying vacuum to said film material in order to reduce the volume of said closed bags, and placing means for placing a number of bags in an outer packaging.
