Description

Automatic tape replacement device The present invention relates to an automatic tape replacement device, and more specifically, to an automatic tape replacement device in which a plurality of adhesive tapes are coupled to a plurality of rotating bars that are installed on a column of the main body of a box packaging device that attaches tape to a packaging box conveyed by a guide roller and rotated by a motor, and when the thickness of the existing adhesive tape in use falls below a certain level, the rotating bars rotate at a certain angle to bring the non-adhesive surface of a new adhesive tape into surface contact with the adhesive surface of the existing adhesive tape, thereby automatically replacing the adhesive tape. Generally, a packaging box is a standardized box structure in the shape of a rectangular prism designed to transport various contents placed inside; it is finished by sealing it with tape after filling it with contents. A box packaging taping machine is used to tape the open parts of the box while it is filled with contents. A taping machine for box packaging comprises a main body, a guide roller installed on the upper surface of the main body in the direction of box movement, a pair of transfer conveyor units installed facing each other to be positioned above the guide roller to forcibly move the packaging box, a support column erected above the main body, a lifting member installed on the support column, and a taping unit installed on the lifting member. Conventional box packaging taping machines are configured with only one taping unit in which a tape roll is installed. Therefore, when the tape on the tape roll is depleted, the taping machine must be stopped and a person must manually replace the tape roll to perform the work, which causes a problem of work delay due to tape replacement. To solve this problem, Korean Public Patent No. 10-2016-0146101, "Box Packaging Device Capable of Automatic Replacement of Adhesive Tape," was developed. The box packaging device capable of automatic replacement of adhesive tape comprises a lifting platform installed on a support mounted on a frame so as to be movable up and down, a plate fixed to the lifting platform and equipped with a guide rail on its front, a sliding panel that slides left and right along the plate, a plurality of adhesive tape applicators installed spaced apart from the sliding panel after attaching and cutting adhesive tape to the upper surface of the box, and a cylinder installed on the plate with a rod end fixed to the sliding panel. When the adhesive tape provided in any of the plurality of adhesive tape applicators is depleted, the rod of the cylinder is advanced or retracted to position the adhesive tape applicator with remaining adhesive tape above the adhesive position of the box, thereby allowing the adhesive tape attachment operation to be performed continuously without interruption. However, conventional box packaging devices capable of automatically replacing adhesive tapes had a problem in that they did not perform the operation of connecting the existing adhesive tape with the new adhesive tape, resulting in a decrease in adhesive strength at the connection point between the existing and new adhesive tapes and frequent adhesion failures.
