Vertical type of bag-making, filling and packaging apparatus and a packaging method thereof

A vertical packaging method, comprising:

• using a former to wind a film sheet around a vertical chute pipe, the former and the chute pipe being supported by support members, the support members being supported by at least one load cell at a position above said at least one load cell;
• joining the sides of the film sheet wound on the chute pipe to form a cylinder of the film sheet the cylinder being supported by the former;
• laterally sealing a bottom portion of the cylinder;
• placing goods in the cylinder with the laterally sealed bottom;
• using the at least one load cell to structurally support the support members at a position above the at least one load cell;
• using the at least one load cell to measure a total weight of the cylinder containing the goods for at least one bag, the former, the chute pipe and the support members;
• transmitting an electric signal of the total weight from the at least one load cell to a controller, the controller calculating a net weight of the goods in the cylinder and controlling a weighing unit to control the weight of the goods to be put in the bag to a predetermined value
• drawing the cylinder downward a predetermined distance with a vacuum draw-down device;
• sealing the top of the bag filled with goods;
• and
• separating the bag having its top sealed from the cylinder.

A method of packaging, comprising:

• using a former to wind a film sheet from a bobbin around a chute pipe that is coaxial with and vertical to the former, the former and the chute pipe being supported by support members and the support members being supported by at least one load cell at a position above said at least one load cell;
• joining the sides of the film sheet wound on the chute pipe with a vertical heat sealer to form a cylinder of the film sheet, the cylinder being supported by the former;
• using a lateral heat sealer to laterally seal a bottom portion of the cylinder protruding from the lower end of the chute pipe;
• placing goods in the cylinder with the laterally sealed bottom using the chute pipe as a conduit for the goods;
• using the at least one load cell to structurally support the support members at a position above the at least one load cell;
• using the at least one load cell to measure a total weight of the cylinder containing the goods for at least one bag, the former, the chute pipe and the support members;
• transmitting an electric signal of the total weight from the at least one load cell to a controller, the controller calculating a net weight of the goods in the cylinder and controlling a weighing unit to control the weight of the goods to be put in the bag to a predetermined value;
• drawing the cylinder downward a distance corresponding to one bag with a vacuum draw-down device;
• simultaneously sealing the top of the bag filled with goods and sealing the bottom of a subsequent bag;
• and
• separating the bag having its top sealed from the cylinder.
