Packaging apparatus for packaging bags equipped with label printer

A packaging apparatus for packaging bags equipped with a label printer that automatically feeds bags manufactured in a pouch type with a half-cut top, opens tops of the bags, puts a product into the bags, packs the bags through sealing, and then discharges the bags, the packaging apparatus comprising:

• a frame equipped with components for operating and controlling the apparatus therein;
• a bag feeding unit automatically conveying and feeding half-cut and wound bags;
• a label attaching unit installed on the frame and printing and attaching a label to the bags that are conveyed;
• and
• an opening and sealing unit opening tops of the bags, putting a product into the bags, and then packing the bags through sealing,
• wherein a PC controlling operation of the apparatus, an electric part box keeping various electric parts for operating the apparatus, a compressor supplying air for opening tops of bags are installed inside the frame, and the PC and the compressor are spaced apart from each other such that the electric part box is disposed between the PC and the compressor,
• wherein the opening and sealing unit includes:
• a nozzle opening a top of a bag that is conveyed by instantaneously blowing air, which is supplied from the compressor, to a width-directional center portion of the bag;
• a pair of blowers installed at both sides of the nozzle, respectively, and keeping the bag with the top open by the nozzle inflated by blowing air to the top of the bag by rotating fans;
• and
• a sealing mean sealing the top of the bag after a product is put into the bag through the open top,
• wherein the sealing mean includes:
• a heating bar installed to be positioned in a portion where a slit, which is formed in a left-right direction on a front plate vertically installed on a front of the frame, is formed, and kept heated at a predetermined temperature for sealing;
• a supporting bar formed in a U-shape, installed in front of the heating bar, operated to move forward and backward, and pressing a top of a bag with a product therein into close contact with a portion right over the slit formed in the front plate of the frame;
• a pair of rotary cylinders installed on the front plate of the frame and having grippers bent in an L-shape at front ends and being rotated such that the bending portions are inserted into both ends of a bag with a product therein and grip the ends to straightly flatten the bag;
• and
• a pair of operation buttons applying a signal to operate the heating bar, the supporting bar, and the rotary cylinders, and
• wherein a heat-resistant sponge is attached to a surface of the supporting bar to prevent from transferring to the supporting bar even though the heating bar is heated.
