PROBLEM TO BE SOLVED: To provide a roll type automatic packaging machine capable of preventing powder biting failure in a lateral seal operation by preventing a powder stirring-up phenomenon generated in a conventional roll type automatic packaging machine.SOLUTION: This seal roll mechanism of a roll type automatic packaging machine comprises: a pocket seal roll device initially applying a pocket seal part to an overlaid packaging films; a longitudinal seal roll device applying a longitudinal seal part to the packaging films after powder raw material is charged into the pocket seal part; and a lateral seal roll device applying a lateral seal part to the packaging films to which the longitudinal seal part is applied to turn it into a sealed package. By receiving the powder raw material falling from a raw material supply device at the pocket seal part of the pocket seal roll device, the fall distance of the powder raw material is shortened to prevent the powder stirring-up phenomenon accompanying the powder raw material dropping operation. |
