Patent ID: 7854245

Claim:
A packing bag forming device for forming a radio frequency identification (RFID) tag on a packing bag, comprising: a tag peeling mechanism comprising a plurality of rollers and a separation plate, wherein the rollers are used to guide a release film of a roll of tag web to a first side of the separation plate for moving the release film along a feeding direction of a packing material in the packing bag forming device, and to guide the release film to a second side of the separation plate when the release film approaches a side surface of the packing material, so as to move the release film along a reverse direction of the feeding direction of the packing material, thereby peeling RFID tags equidistantly and longitudinally arranged on the release film from the release film due to an abrupt change of a moving direction of the release film, while the peeled RFID tags continue to move along the feeding direction of the packing material; a tag transferring mechanism comprising a pressing roller and a driving element, wherein the pressing roller is disposed at a position adjacent to an end edge of the separation plate, and controlled by the driving element to regularly and intermittently move, and wherein the pressing roller can shift and abut against an upper surface of the RFID tags when the RFID tags are peeled from the release film, so that an adhesive layer on a lower surface of the RFID tags is attached to the side surface of the packing material due to a pressing force of the pressing roller; a tag fixing mechanism comprising a melting mold and a forming plate, wherein the melting mold is disposed at a position corresponding to the forming plate, for bonding a substrate portion of the RFID tags which is provided with neither an antenna nor a chip to the packing material with a melting technology when the RFID tags and the packing material are passed through between the melting mold and the forming plate, so as to secure and equidistantly and longitudinally arrange the RFID tags at predetermined positions on the side surface of the packing material; a folding mechanism for folding two opposite side edges of the packing material, so that the two opposite side edges overlap each other, and one of two side surfaces of the packing material that is attached with the RFID tags becomes, after being folded, an inner side surface of a packing bag; a sealing mechanism for sealing the two opposite side edges of the packing material with a melting technology, so as to continuously and longitudinally form a plurality of packing bags from the packing material, wherein each of the packing bags has an outer or inner side surface securely installed with one of the RFID tags at a predetermined position thereon; and a cutting mechanism for equidistantly and transversely cutting off, one by one, the packing bags which are longitudinally linked one after another, so as to complete the plurality of packing bags.
